The diagnosis and treatment of nail conditions are necessary competencies for board-certified dermatologists, but appropriate education often is lacking.¹ The American Academy of Dermatology (AAD) annual meeting is one of the largest and most highly attended dermatology educational conferences worldwide. We sought to determine the number of hours dedicated to nail-related topics at the AAD annual meetings from 2013 to 2019.

We accessed programs from the AAD annual meetings archive online (https://www.aad.org/meetings/previous-meetings-archive), and we used hair and psoriasis content for comparison. Event titles and descriptions were searched for nail-related content (using search terms nail, onychia, and onycho), hair-related content (hair, alopecia, trichosis, hirsutism), and psoriasis content (psoriasis). Data acquired for each event included the date, hours, title, and event type (eg, forum, course, focus session, symposium, discussion group, workshop, plenary session).

The number of hours dedicated to nail education consistently lagged behind those related to hair and psoriasis content during the study period (Figure 1). According to the AAD, the conference runs Friday to Tuesday with higher attendance Friday to Sunday (Tim Moses, personal communication, July 9, 2019). Lectures during the weekend are likely to have a broader reach than lectures on Monday and Tuesday. The proportion of nail content during weekend prime time slots was similar to that of hair and psoriasis (Figure 2). Plenary sessions often are presented by renowned experts on hot topics in dermatology. Notably, hair (2014-2015) and psoriasis (2015-2017) content were represented in the plenary sessions during the study period, while nail content was not featured.

A limitation of this study was the lack of online data available for AAD annual meetings before 2013, so we were unable to characterize any long-term trends. Furthermore, we were unable to assess the educational reach of these sessions, as data on attendance are lacking.

This study demonstrates a paucity of nail-related content at the AAD annual meetings. The introduction of the “Hands-on: Nail Surgery” in 2015 is an important step forward to diminish the knowledge gap in the diagnosis of various nail diseases and malignancies. We recommend increasing the number of hours and overall content of didactic nail sessions at the AAD annual meeting to further the knowledge and procedural skills of dermatologists in caring for patients with nail disorders.

Male facial hair trends are continuously changing and are influenced by culture, geography, religion, and ethnicity.¹ Although the natural pattern of these hairs is largely androgen dependent, the phenotypic presentation often is a result of contemporary grooming practices that reflect prevailing trends.² Beards are common throughout adulthood, and thus, preserving this facial hair pattern is considered with reconstructive techniques.^3,4 Male facial skin physiology and beard hair biology are a dynamic interplay between both internal (eg, hormonal) and external (eg, shaving) variables. The density of beard hair follicles varies within different subunits, ranging between 20 and 80 follicles/cm². Macroscopically, hairs vary in length, diameter, color, and growth rate across individuals and ethnicities.^1,5

There is a paucity of literature assessing if male facial hair offers a protective role for external insults. One study utilized dosimetry to examine the effectiveness of facial hair on mannequins with varying lengths of hair in protecting against erythemal UV radiation (UVR). The authors concluded that, although facial hair provides protection from UVR, it is not significant.⁶ In a study of 200 male patients with actinic keratosis on the head and face, Liu et al⁷ demonstrated that sheltering mustaches, defined as greater than 9 mm in length, reduced the risk for developing an actinic keratosis on the lower lip by a factor of 16 (P=.0003).

We sought to determine if facial hair growth is implicated in the diagnosis and treatment of cutaneous malignancies. Specifically, we hypothesized that the presence of facial hair leads to a delay in diagnosis with increased subclinical growth given that tumors may be camouflaged and go undetected. Although there is a lack of literature, our anecdotal evidence suggests that male patients with facial hair have larger tumors compared to patients who do not regularly maintain any facial hair.

Methods

We performed a retrospective chart review following approval from the institutional review board at The University of North Carolina at Chapel Hill. We identified all male patients with a cutaneous malignancy located on the face who were treated from January 2015 to December 2018. Photographs were reviewed and patients with tumors located within the following facial hair-bearing anatomic subunits were included: lip, melolabial fold, chin, mandible, preauricular cheek, buccal cheek, and parotid-masseteric cheek. Tumors located within the medial cheek were excluded.

Facial hair growth was determined via image review. Because biopsy photographs were not uploaded into the health record for patients who were referred externally, we reviewed all historical photographs for patients who had undergone prior Mohs micrographic surgery at The University of North Carolina at Chapel Hill, preoperative photographs, and follow-up photographs as a proxy to determine facial hair status. Postoperative photographs taken within 2 weeks following surgery were not reviewed, as any facial hair growth was likely due to disinclination on behalf of the patient to shave near or over the incision. Age, number of days from biopsy to surgery, pathology, preoperative tumor size, number of Mohs layers, and defect size also were extrapolated from our chart review.

Statistical Analysis
Summary statistics were applied to describe demographic and clinical characteristics. An unpaired 2-tailed t test was utilized to test the null hypothesis that the mean difference was zero. The χ² test was used for categorical variables. Results achieving P<.05 were considered statistically significant.

Results

We reviewed medical records for 171 patients with facial hair and 336 patients without facial hair. The primary outcomes for this study assessed tumor and defect size in patients with facial hair compared to patients with no facial hair (Table 1). On average, patients who had facial hair were younger (67.5 years vs 74.0 years, P<.001). The median number of days from biopsy to surgery (43.0 vs 44.0 days) was comparable across both groups. The majority of patients (47%) exhibited a beard, while 30% had a mustache and 23% had a goatee. The most common tumor location was the preauricular cheek for both groups (29% and 28%, respectively). The mean preoperative tumor size in the facial hair cohort was 1.40 cm compared to 1.22 cm in the group with no facial hair (P=.03). The mean number of Mohs layers in the facial hair cohort was 1.53 compared to 1.33 in the group with no facial hair (P=.03). The facial hair cohort also had a larger mean postoperative defect size (2.18 cm) compared to the group with no facial hair (1.98 cm); however, this finding was not significant (P=.05).

We then stratified our data to analyze only lip tumors in patients with and without a mustache (Table 2). The mean preoperative tumor size in the mustache cohort was 1.10 cm compared to 0.82 cm in the group with no mustaches (P=.046). The mean number of Mohs layers in the mustache cohort was 1.57 compared to 1.42 in the group with no mustaches (P=.43). The mustache cohort also had a larger mean postoperative defect size (1.63 cm) compared to the group with no facial hair (1.33 cm), though this finding also did not reach significance (P=.13).

Comment

Our findings support anecdotal observations that tumors in men with facial hair are larger, require more Mohs layers, and result in larger defects compared with patients who are clean shaven. Similarly, in lip tumors, men with a mustache had a larger preoperative tumor size. Although these patients also required more Mohs layers to clear and a larger defect size, these parameters did not reach significance. These outcomes may, in part, be explained by a delay in diagnosis, as patients with facial hair may not notice any new suspicious lesions within the underlying skin as easily as patients with glabrous skin.

Although facial hair may shield skin from UVR, we agree with Parisi et al⁶ that this protection is marginal at best and that early persistent exposure to UVR plays a much more notable role in cutaneous carcinogenesis. As more men continue to grow facial hairstyles that emulate historical or contemporary trends, dermatologists should emphasize the risk for cutaneous malignancies within these sun-exposed areas of the face. Although some facial hair practices may reflect cultural or ethnic settings, the majority reflect a desired appearance that is achieved with grooming or otherwise.

Skin cancer screening in men with facial hair, particularly those with a strong history of UVR exposure and/or family history, should be discussed and encouraged to diagnose cutaneous tumors earlier. We encourage men with facial hair to be cognizant that cutaneous malignancies can arise within hair-bearing skin and to incorporate self–skin checks into grooming routines, which is particularly important in men with dense facial hair who forego regular self-care grooming or trim intermittently. Furthermore, we urge dermatologists to continue to thoroughly examine the underlying skin, especially in patients with full beards, during skin examinations. Diagnosing and treating cutaneous malignancies early is imperative to maximize ideal functional and cosmetic outcomes, particularly within perioral and lip subunits, where marginal millimeters can impact reconstructive complexity.

Conclusion

Men with facial hair who had cutaneous tumors in our study exhibited larger tumors, required more Mohs layers, and had a larger defect size compared to men without any facial hair growth. Similar findings also were noted when we stratified and compared lip tumors in patients with and without mustaches. Given these observations, patients and dermatologists should continue to have a high index of suspicion for any concerning lesion located within skin underlying facial hair. Regular screening in men with facial hair should be discussed and encouraged to diagnose and treat potential cutaneous tumors earlier.

To the Editor:

Ongoing concern about the high costs of dermatology residency interviews has led to several cost-saving proposals, as presented by Hussain¹ in the Cutis article, “Reducing the Cost of Dermatology Residency Applications: An Applicant’s Perspective.” Additional strategies to reduce applicant costs include eliminating travel costs through video or telephone interviews, interviewing students who are visiting during their away rotation, and developing and implementing a mechanism to exempt students from participating in the Electronic Residency Application Service (ERAS) and the National Resident Matching Program (NRMP).² A potential mechanism for the latter suggestion could be a binding early decision program for dermatology residency. Binding early decision has been successfully employed by medical schools for many years.³ Under this model for dermatology residency, applicants may apply to 1 dermatology residency program by the early deadline and the program would have the option of accepting as many of the early-decision applicants as the number of residency positions in their program permits, allowing nonadmitted and nonparticipating applicants time to apply through the usual ERAS/NRMP cycle. There are several potential advantages to this model that would decrease the number of applicants applying to all the available dermatology residency programs each cycle.

First, because applicants would be limited to 1 application to participate in the early decision program, they must realistically consider the strength of their application and weigh their chances for acceptance to that program. Programs could facilitate the process by becoming more transparent about the type of applicants that have previously matched in their program.² If an early-decision applicant successfully matches, that applicant would be prohibited from applying to additional dermatology residency programs through ERAS and NRMP during that application cycle.

Second, early-decision actions by programs—probably by August 1, a time when most third-year medical students have completed their academic year—would be determined before ERAS releases applications to residency programs. This timeline would remove successful applicants in the early decision program from going to additional interviews and incurring the associated travel costs.

Third, early decision could be potentially beneficial to applicants who are tied to a specific geographic region for training and to programs with specific program needs, such as expertise in specific areas of dermatology research or areas of clinical need (eg, adding a dermatopathologist, plastic surgeon, internist, or a pediatrician to the residency program who now wants dermatology training) or other program needs.

Fourth, application costs could potentially be lower for early-decision applicants than through the present application process if participating institutions waived application fees. Applicants would still be responsible for submitting requested academic transcripts, letters of recommendation, and travel expenses if an on-site interview is requested by the program.

Finally, highly desirable applicants who are offered a position through early decision would result in more opportunities for other applicants to interview for the remaining available residency positions through ERAS/NRMP.

Downsides to early decision for dermatology residency include the inability of applicants to compare programs to one another through their personal experiences, such as prior rotations or interviews, and for programs to compare applicants though the interview process and away rotations. In addition, US Medical Licensing Examination Step 2 scores and Alpha Omega Alpha honor medical society status and other academic honors may not be available to programs to consider at the time of early decision. Cooperation would be needed with ERAS and NRMP to create an early decision program for dermatology residency.

One other potential consequence of the early match could involve instances of strained relationships between research fellows and their sponsoring institution or dermatology program. Research fellows often match at their research institution, and failing to early match could potentially sour the relationship between the applicant and the program, thus leading to a less productive year. However, many programs participating in an early match will probably have additional residency positions remaining in the traditional match that would be still available to the fellows.

The concept of an early-binding residency match process has the potential to save both time and money for programs and applicants. Although an early-match process would have many positive effects, there also would be inherent downsides that accompany such a system. Nonetheless, an early-match process in dermatology has the prospect of efficiently pairing applicants and programs that feel strongly about each other while simplifying the match process and reducing costs for all parties involved.

Author’s Response

The early decision option for dermatology residency applications would be a welcomed addition to the process but may be complicated by 2 recent events: the coronavirus disease 2019 (COVID-19) pandemic and the change of US Medical Licensing Examination (USMLE) Step 1 score reporting to a pass/fail system.

The COVID-19 pandemic has caused remarkable economic distress and likely affects medical students more acutely given their high levels of debt. As Ryan and Wagner observed, one advantage of the early-decision option would be financial relief for certain students. If applicants successfully match during the early-decision phase, they will not need to apply to any additional dermatology programs and also can target their preliminary-year applications to the geographic region where they have already matched.

In addition, the COVID-19 pandemic may further reduce early applicants’ ability to visit programs in person. Various medical schools have curtailed away rotations, and programs may opt for virtual interviews in accordance with social distancing guidelines.¹ Thus, early applicants will have even fewer opportunities to compare programs before they must make a binding decision about their residency placement. Although away rotations and interview travel are some of the largest drivers of application cost,² reducing costs in this way might shortchange both students and programs.

Arguably, the change in USMLE Step 1 score reporting beginning in 2022 may impact residency selection for a longer period of time than the COVID-19 pandemic. Program directors cited USMLE Step 1 scores as one of the main factors determining which applicants may be invited to interview.³ The lack of numerical USMLE Step 1 scores may encourage programs to place more weight on other metrics such as USMLE Step 2 CK scores or Alpha Omega Alpha membership.⁴ However, as Ryan and Wagner point out, such metrics may not be available in time for early-decision applicants.

As such, future program directors will have precious little information to screen early-decision applicants and may need to conduct holistic application review. This would require increased time and manpower compared to screening based on traditional metrics but may lead to a better “fit” for an applicant with a residency.

In general, implementation of any early decision program would benefit dermatology applicants as a group by removing elite candidates from the applicant pool. According to National Resident Matching Program data, just 3% of dermatology applicants account for more than 12% of overall interviews.⁵ In other words, a small group of the strongest applicants receives a lion’s share of interviews, crowding out many other candidates. Removing these top-tier applicants likely would provide remaining applicants with a higher return on investment per application, and students may choose to save money by applying to fewer programs.

Adopting early-decision options within the dermatology match may be complicated given the COVID-19 pandemic and USMLE score changes but may spur positive changes in the process while also reducing the financial burden on applicants.

To the Editor:

Ongoing concern about the high costs of dermatology residency interviews has led to several cost-saving proposals, as presented by Hussain¹ in the Cutis article, “Reducing the Cost of Dermatology Residency Applications: An Applicant’s Perspective.” Additional strategies to reduce applicant costs include eliminating travel costs through video or telephone interviews, interviewing students who are visiting during their away rotation, and developing and implementing a mechanism to exempt students from participating in the Electronic Residency Application Service (ERAS) and the National Resident Matching Program (NRMP).² A potential mechanism for the latter suggestion could be a binding early decision program for dermatology residency. Binding early decision has been successfully employed by medical schools for many years.³ Under this model for dermatology residency, applicants may apply to 1 dermatology residency program by the early deadline and the program would have the option of accepting as many of the early-decision applicants as the number of residency positions in their program permits, allowing nonadmitted and nonparticipating applicants time to apply through the usual ERAS/NRMP cycle. There are several potential advantages to this model that would decrease the number of applicants applying to all the available dermatology residency programs each cycle.

First, because applicants would be limited to 1 application to participate in the early decision program, they must realistically consider the strength of their application and weigh their chances for acceptance to that program. Programs could facilitate the process by becoming more transparent about the type of applicants that have previously matched in their program.² If an early-decision applicant successfully matches, that applicant would be prohibited from applying to additional dermatology residency programs through ERAS and NRMP during that application cycle.

Second, early-decision actions by programs—probably by August 1, a time when most third-year medical students have completed their academic year—would be determined before ERAS releases applications to residency programs. This timeline would remove successful applicants in the early decision program from going to additional interviews and incurring the associated travel costs.

Third, early decision could be potentially beneficial to applicants who are tied to a specific geographic region for training and to programs with specific program needs, such as expertise in specific areas of dermatology research or areas of clinical need (eg, adding a dermatopathologist, plastic surgeon, internist, or a pediatrician to the residency program who now wants dermatology training) or other program needs.

Fourth, application costs could potentially be lower for early-decision applicants than through the present application process if participating institutions waived application fees. Applicants would still be responsible for submitting requested academic transcripts, letters of recommendation, and travel expenses if an on-site interview is requested by the program.

Finally, highly desirable applicants who are offered a position through early decision would result in more opportunities for other applicants to interview for the remaining available residency positions through ERAS/NRMP.

Downsides to early decision for dermatology residency include the inability of applicants to compare programs to one another through their personal experiences, such as prior rotations or interviews, and for programs to compare applicants though the interview process and away rotations. In addition, US Medical Licensing Examination Step 2 scores and Alpha Omega Alpha honor medical society status and other academic honors may not be available to programs to consider at the time of early decision. Cooperation would be needed with ERAS and NRMP to create an early decision program for dermatology residency.

One other potential consequence of the early match could involve instances of strained relationships between research fellows and their sponsoring institution or dermatology program. Research fellows often match at their research institution, and failing to early match could potentially sour the relationship between the applicant and the program, thus leading to a less productive year. However, many programs participating in an early match will probably have additional residency positions remaining in the traditional match that would be still available to the fellows.

The concept of an early-binding residency match process has the potential to save both time and money for programs and applicants. Although an early-match process would have many positive effects, there also would be inherent downsides that accompany such a system. Nonetheless, an early-match process in dermatology has the prospect of efficiently pairing applicants and programs that feel strongly about each other while simplifying the match process and reducing costs for all parties involved.

Author’s Response

The early decision option for dermatology residency applications would be a welcomed addition to the process but may be complicated by 2 recent events: the coronavirus disease 2019 (COVID-19) pandemic and the change of US Medical Licensing Examination (USMLE) Step 1 score reporting to a pass/fail system.

The COVID-19 pandemic has caused remarkable economic distress and likely affects medical students more acutely given their high levels of debt. As Ryan and Wagner observed, one advantage of the early-decision option would be financial relief for certain students. If applicants successfully match during the early-decision phase, they will not need to apply to any additional dermatology programs and also can target their preliminary-year applications to the geographic region where they have already matched.

In addition, the COVID-19 pandemic may further reduce early applicants’ ability to visit programs in person. Various medical schools have curtailed away rotations, and programs may opt for virtual interviews in accordance with social distancing guidelines.¹ Thus, early applicants will have even fewer opportunities to compare programs before they must make a binding decision about their residency placement. Although away rotations and interview travel are some of the largest drivers of application cost,² reducing costs in this way might shortchange both students and programs.

Chronic lymphocytic leukemia is characterized by significant immune perturbation, including significant impairment of natural killer (NK) cells, which leads to disease complications and reduced effectiveness of treatment.

However, the use of recombinant human interleukin-27 (IL-27) was able to increase cytotoxic effects of bone marrow natural killer cells in chronic lymphocytic leukemia (CLL), according to an in vitro study conducted by Maral Hemati, a student researcher at the Semnan (Iran) University of Medical Sciences, and colleagues.

Ms. Hemati and her colleagues obtained bone marrow aspirates (BM) and peripheral blood samples (PB) were from 12 untreated CLL patients (9 men and 3 women) with a median age of 61 years. The cells were cultured in vitro, according to their report in International Immunopharmacology.

The researchers found that the use of recombinant human interleukin-27 (IL-27) stimulated NK cells in the cultured BM and PB cells of CLL patients, based upon assessment using cell surface flow cytometry and a cytotoxicity assay.

Treatment with IL-27 also increased CD69 (a marker for NK cell activity) on NK cells both in BM and PB. In addition, BM-NK cells treated with IL-27 exhibited a significant increase in degranulation and NK cell–mediated cytotoxicity (P < .001) as compared with untreated NK cells, whereas it did not improve NK cell activity of PB, according to the researchers.

The research was supported by Semnan (Iran) University of Medical Sciences. The authors reported that they had no conflicts of interest.

To the Editor:

A thorough full-body skin examination (FBSE) is an integral component of a dermatologic encounter and helps identify potentially malignant and high-risk lesions, particularly in areas that are difficult for the patient to visualize.¹ Despite these benefits, many patients experience discomfort and anxiety about this examination because it involves sensitive anatomical areas. The true psychological impact of an FBSE is not clearly understood; however, research into improving patient comfort in these circumstances can have a broad positive impact.² The purpose of this pilot study was to establish patients’ willingness to complete a pre-encounter questionnaire that defines their FBSE preferences as well as to identify the anatomical areas that are of most concern.

This study was approved by the University of Kansas institutional review board as nonhuman subjects research. A pre-encounter questionnaire that included information about the benefits of FBSEs was administered to 34 patients, allowing them to identify anatomic locations that they wanted to exclude from the FBSE.

Following the patient visit (in which the identified anatomical locations were excluded), patients were given a brief exit survey that asked about (1) their preference for a pre-encounter FBSE questionnaire and (2) the impact of the questionnaire on their anxiety level throughout the encounter. Preference for asking was surveyed using a 10-point scale (10=strong preference for the pre-encounter survey; 1=strong preference against the pre-encounter survey). Change in anxiety was surveyed using a 10-point scale (10=strong reduction in anxiety after the pre-encounter survey; 1=strong increase in anxiety after the pre-encounter survey). Statistical analysis was performed using 2-tailed unpaired t tests, with P<.05 considered statistically significant.

Twenty female and 14 male patients were enrolled (mean age, 53 years)(Table). The most commonly excluded anatomical location on the pre-encounter survey was the genitals, followed by the buttocks, breasts/chest, legs, feet, and abdomen (Table); 10 (71%) male and 13 (65%) female respondents did not exclude any component of the FBSE.

The small sample size was a limitation of this study. Future studies can assess with greater precision the clear benefits of a pre-encounter survey as well as the benefits or drawbacks of a survey compared to other modalities that are aimed at reducing patient anxiety about the FBSE, such as having the physician directly ask the patient about areas to avoid during the examination.

A pre-encounter survey about the FBSE can serve as an efficient means of determining patient preference and reducing self-reported anxiety about the visit.

Actinic keratosis (AK) is the most common cutaneous lesion and is regarded as a precursor to nonmelanoma skin cancer (NMSC), particularly squamous cell carcinoma (SCC).¹ Field cancerization refers to broad areas of chronically sun-exposed skin that show cumulative sun damage in the form of clinical and subclinical lesions. It is not feasible to treat large areas with multiple overt and subclinical lesions using surgical methods, and photodynamic therapy (PDT) has become a preferred method for treatment of field cancerization.² Topical PDT uses the heme biosynthesis pathway precursors aminolevulinic acid (ALA) or methyl ALA (MAL), which localizes in the treatment area and is metabolized to protoporphyrin IX.³ After an incubation period, activation by a light source results in the formation of cytotoxic oxygen species,⁴ with reports of efficacy over large areas and excellent cosmetic outcomes.²

Laser ablative fractional resurfacing (AFR) also has been investigated as a treatment of AKs; CO₂ laser AFR treatment resulted in a short-term reduction in the number of AK lesions and appeared to reduce the development of new lesions.⁵ However, case reports and small studies have indicated that pretreatment with laser AFR can increase the efficacy of PDT by creating microscopic vertical channels facilitating deeper penetration and uptake of the ALA.⁶ The use of erbium:YAG lasers in combination with PDT has demonstrated notable clinical and aesthetic improvements in treating basal cell carcinomas (BCCs)⁷ and AKs,⁸ with enhanced efficacy in moderate to thick AKs in particular. Hædersdal et al⁶ reported that CO₂ laser AFR facilitated delivery of MAL into porcine skin, with AFR appearing to bypass the stratum corneum and deliver the treatment to the deep dermis.

The combination of CO₂ laser AFR and PDT has shown statistically significant increases in efficacy for treatment of AKs compared to PDT alone (P<.001).⁹ In a small study, Alexiades¹⁰ reported a statistically significant improvement in AKs at 4 and 8 weeks posttreatment for 10 patients receiving CO₂ laser AFR-PDT vs conventional PDT (P<.05). Studies of organ transplant recipients—who are at higher risk for AK and NMSC development—demonstrated favorable results for combined CO₂ laser AFR and PDT vs either laser treatment¹¹ or PDT^9,12 alone, with significant reductions in the number of AKs (P=.002). Results were maintained for 3 to 4 months after treatment. Additional studies have shown that combining CO₂ laser AFR and PDT may reduce the PDT incubation time or number of treatments required to achieve a response over conventional PDT.^13,14

Our proof-of-concept study was designed to assess efficacy of CO₂ laser AFR to enhance an approved drug delivery system in the treatment of AK and NMSC. The objective was to compare effect and durability of AFR-PDT vs standard ALA-PDT in the treatment of AK and NMSCs in a split-sided study of various body locations.

Methods

This randomized, split-sided study compared CO₂ laser AFR-PDT to standard ALA-PDT for the treatment of AK and NMSC conducted at 1 site in Los Gatos, California. Patients who had a skin cancer screening and received a biopsy diagnosis of AK or NMSC were invited to attend an enrollment visit. Key inclusion criteria for enrollment were male or female patients aged 40 to 85 years with notable symmetrically comparable photodamage (at least 1 AK per square centimeter) in 1 or more skin areas—scalp, face, or distal extremities—with presence of clinically identifiable NMSCs proven by biopsy. Key exclusion criteria were patients who were pregnant; patients with epilepsy, seizures, or a photosensitive disorder; those taking photosensitizing medication (eg, doxycycline, hydrochlorothiazide); or immunocompromised patients. The study was approved by an institutional review board (Salus IRB [Austin, Texas]), and each participant underwent a complete and informed consent process.

Laterality for pretreatment with AFR followed by ALA-PDT vs ALA-PDT alone was determined at the time of treatment using a computer-based random number generator; even numbers resulted in pretreatment of the right side, and odd numbers resulted in pretreatment of the left side. Because of the difference in pretreatment methods for the 2 sides, it was not possible to perform the procedure under blinded conditions.

The treatment area was prepared by defatting the entire site with 70% isopropyl alcohol, followed by benzalkonium chloride antibacterial cleansing for the AFR pretreatment side. A 7% lidocaine/7% tetracaine ointment was applied under polyethylene wrap occlusion to the AFR pretreatment side for 20 minutes. Additionally, nerve blocks and field blocks with a mixture of 1.1% lidocaine with epinephrine/0.5% bupivacaine with epinephrine were performed wherever feasible. After 20 minutes, the lidocaine-tetracaine ointment was removed with isopropanol, and AFR treatment commenced immediately with the SmartXide DOT laser (DEKA)(1 pass of 25 W, 1200-microsecond duration at 500-µm spacing, 200-µm spot size, achieving 12% surface area ablation). Hyperkeratotic treated areas were debrided with saline and received a second pass with the laser. Aminolevulinic acid solution 20% (Levulan Kerastick; DUSA Pharmaceuticals, Inc)¹⁵ was applied to both sides of the treatment area and allowed to absorb for a 1-hour incubation period, which was followed by blue-light exposure at a power density of 10 mW/cm² for 16 minutes and 40 seconds using the BLU-U Photodynamic Therapy Illuminator (DUSA Pharmaceuticals, Inc). Areas treated with AFR were then covered with a layer of Aquaphor ointment (Beiersdorf, Inc) and an absorptive hydrogel dressing for48 to 96 hours, with continued application of the ointment until resolution of all crusting. After treatment, patients were instructed to avoid direct sun exposure, wear a hat or visor for the first 2 weeks posttreatment when outdoors, and apply sunscreen with a sun protection factor greater than 30 once skin had healed.

Results

Twenty-four potential participants experiencing AKs and/or NMSCs were screened for the study, with 19 meeting inclusion criteria. All participants were white, non-Hispanic, and had Fitzpatrick skin types I or II. Treated areas for all participants had field cancerization defined as at least 1 AK per square centimeter. All 19 participants enrolled in the study completed the posttreatment evaluations up to 6 months. All AFR-pretreated sites showed superior results in reduction in number, size, or hyperkeratosis of AKs at all follow-up visits, with a complete absence of new AK formation at the 6-month follow-up (Table). Conversely, sites treated with standard PDT only showed some recurrence of AKs at 6 months. Of the 3 participants who had biopsy-confirmed BCCs on the AFR-pretreated side, there were 3 persistent lesions after treatment at the 6-month visit. Two participants experienced persistence of a confirmed SCC in situ that was on the laser-pretreated side only (1 on the forehead and 1 on the hand), whereas 1 participant with an SCC on the leg at baseline had no recurrence at 6 months. A participant who received treatment on the lower lip had persistence of actinic cheilitis on both the AFR- and non–AFR-treated sides of the lip.

Scalp and facial sites healed fully in an average of 7 days, whereas upper extremities—forearm and hands—took approximately 14 days to heal completely. Lower extremity AFR-pretreated sites exhibited substantial weeping, resulting in prolonged healing of approximately 21 days for resolution of all scabbing. Pain during treatment was mild to moderate, as field blocks with local anesthesia and topical anesthetic were used prior to AFR treatment. No novel adverse events were reported in the combined use of laser AFR and PDT; all adverse events noted have been recorded in studies of the separate techniques.^16,17

Comment

In this split-sided study in patients with field cancerization, the use of CO₂ laser AFR before treatment with PDT increased AK lesion clearance compared to ALA-PDT alone. Prior studies of fractional laser–assisted drug delivery on porcine skin using topical MAL showed that laser channels approximately 3-mm apart were able to distribute protoporphyrin through the entire skin.⁶ The ablative nature of AFR theoretically provides deeper and more effusive penetration of the ALA solution than using conventional PDT or erbium:YAG lasers with PDT.^7,8 Helsing et al¹¹ applied CO₂ laser AFR MAL-PDT to AKs in organ transplant recipients and obtained complete responses in 73% of patients compared to a complete response of 31% for AFR alone. The results reported in our study are consistent with Helsing et al,¹¹ showing a complete clinical response for 14 of 19 patients (74%), of whom 4 (21%) had no recurrence of NMSC and 10 (53%) had no recurrence of AK on the AFR-PDT–treated side.

The pretreatment process required for the laser AFR added time to the initial visit compared to conventional PDT, which is balanced by a reduced PDT incubation time (1 hour vs the approved indication of 14–18 hours for face/scalp or 3 hours for upper extremities under occlusion). The use of microneedling as an alternative pretreatment procedure before PDT also has been investigated, with the aim of decreasing the optimum ALA absorption time. The mean reduction in AKs (89.3%) was significantly greater than for PDT alone (69.5%; P<.05) in a small study by Spencer and Freeman.¹⁸ Although microneedling is less time-intensive and labor-intensive than laser AFR, the photocoagulative effect and subsequent microhemorrhages resulting from AFR should result in much deeper penetration of ALA solution than for microneedling.

The limitations of this proof-of-concept study arose from the small sample size of 19 participants and the short follow-up period of 6 months. Furthermore, the unblinded nature of the study could create selection, detection, or reporting bias. Further follow-up appointments would aid in determining the longevity of results, which may encourage future use of this technique, despite the time-consuming preparation. A larger study with follow-up greater than 1 year would be beneficial, particularly for monitoring remission from SCCs and BCCs.

Conclusion

Pretreatment with CO₂ laser AFR before ALA-PDT provided superior clearance of AKs and thin NMSCs at 6 months compared to ALA-PDT alone (Figure). Additionally, the incubation period for ALA absorption can be reduced before PDT, leading to a shorter treatment time overall. The benefits of AFR pretreatment on AK clearance demonstrated in this study warrant further investigation in a larger trial with a longer follow-up period to monitor maintenance of response.

As COVID-19 case levels plateau in some regions, 16 North American cardiovascular societies have released a framework for reintroducing cardiovascular services disrupted by the pandemic.

The consensus document outlines a phased approach to restarting invasive cardiovascular (CV) procedures and diagnostic tests that aims to reduce patient and health care provider exposure to the coronavirus and still provide essential care. It also emphasizes some of the ethical considerations in patient selection and the need for a collaborative approach.

“The key message in our document is we need a new unprecedented collaboration with public health officials so that we can carefully monitor the situation and we’re aware of what’s happening with the penetrance of the pandemic in the community, but they’re aware of the morbidity and mortality that’s occurring on our ever-growing waiting list,” lead author David A. Wood, MD, told theheart.org | Medscape Cardiology.

The recommendations were jointly published May 4 in the Canadian Journal of Cardiology , the Journal of the American College of Cardiology, and The Annals of Thoracic Surgery, and are endorsed by, among others, the American Heart Association, American College of Cardiology (ACC), and Canadian Cardiovascular Society.

The guidance comes as hospitals are facing revenue shortfalls because of canceled elective procedures and resource-intensive COVID-19 cases, prompting some healthcare systems to furlough, lay off, or even fire staff.

“It’s obvious that volumes are down between 40% and 60%,” said Wood, director of the cardiac catheterization laboratory at Vancouver General Hospital and professor of medicine at the University of British Columbia, Canada. “Part of that is that some areas have restricted case volumes totally appropriately and it’s partly because patients are very afraid of coming to the hospital and, unfortunately, are having bad events at home. And some are dying.”

The new report features a detailed table outlining three different response levels: reintroduction of some services (level 2); reintroduction of most services (level 1); and regular services (level 0). It covers a range of services from transthoracic echocardiography and exercise testing with imaging to care for acute coronary syndrome and ST-segment elevation myocardial infarction.

“We’ve learned that we can very quickly turn off the tap and go to doing only 10% of our normal volumes, whether that’s surgery, cath lab, EP, diagnostic tests,” Wood said. “It’s much more difficult to thoughtfully turn the tap part way back on or restart the engine … you don’t just go from 0 to 100 [mph]. You go from 0 to 30 to 60 then maybe to 80 [mph].”

The document also includes eight guiding principles such as:
 

• The expectation that response levels will be different between regions, and even within a given region.
• A “transparent collaborative plan” for COVID-19 testing and personal protective equipment (PPE) must be in place before restarting cases.
• A less invasive test or alternate imaging modality should be considered, if both tests have similar efficacy.
• In general, a minimally invasive procedure with a shorter length of stay is preferable, if both strategies have similar efficacy and safety.

Although previous reports on cath lab considerations during the pandemic or restarting elective surgeries peg various actions to specific thresholds or time intervals, the language here is noticeably and intentionally broad.

Instead of stating when cardiovascular services should resume, for example, the experts say it’s appropriate to put the guidance document into place if there’s a “sustained reduction” in the rate of new COVID-19 admissions and deaths in the relevant geographic region for a “prespecified time interval.”

As for when or how frequently patients and healthcare providers should be tested for COVID-19, the document encourages “routine screening of all patients prior to any cardiovascular procedure or test.”

Overly prescriptive language in previous documents wasn’t felt to be that helpful, whereas language like “selective” cases and “some” or “most” cardiovascular procedures gives clinicians, health systems, and policy makers flexibility when moving between response levels, Wood explained.

“Different regions might be at different levels based on principles of public health as far as the penetrance of the pandemic in that community, as well as how can you actually do the physical distancing in your hospital or ambulatory clinic. Because, I tell you, that is the Achilles heel,” he said. “Our run rates are going to be determined by testing, the availability of PPE, but also how we’re going to use our existing infrastructure and maintain physical distancing.”

That may mean using telehealth for initial visits, having clinics open earlier in the morning or on weekends, or doing partial volumes for surgery or in the cath lab so patients can be staggered and recover at different times and in different areas of the hospital. “These are very granular, specific infrastructure things that we’ve never really had to consider before,” Wood observed.

The document also had to be flexible and nimble enough to respond to a potential rebound of COVID-19 cases, which in newly released models are projected to rise sharply to 200,000 cases a day and be accompanied by some 3,000 deaths each day by June 1.

“This is my own personal opinion but I think it’s foolish to think that we are going to be able to come back to 100% of the cases we were doing before, even with testing, PPE, and all of that until we have a vaccine,” he said.

Similar to decisions made in preparation for the initial COVID-19 surge, the consensus document outlines the need for ethical considerations when turning the tap back on. This means prioritizing procedures and tests that are likely to benefit more people and to a greater degree, and ensuring that patients are treated fairly and consistently, regardless of their ethnicity, perceived social worth, or ability to pay, said coauthor and ACC President Athena Poppas, MD, Brown University School of Medicine, Providence, Rhode Island.

“It’s an ethical tenet that exists in a lot of places but it’s usually not overtly called out,” Poppas told theheart.org | Medscape Cardiology. “It’s not rationing care; I think people jump to that but it’s actually the opposite of rationing care. It’s about being thoughtful about prioritizing patients.”

“There’s a variety of data that should help in the prioritization, not only how much hospital resources are utilized, that’s on one side, but there’s also the patient risk of delaying or doing a procedure, and then the societal risk,” she said.

Susheel Kodali, MD, of New York–Presbyterian Hospital/Columbia University Irving Medical Center, who recently published recommendations on restructuring structural heart disease practice during the pandemic, said the document is timely as centers, including his own, are trying to restart some outpatient visits, as early as next week.

“They made a point about talking about cohesive partnerships with regional public health officials and I think that’s great. The question is how does that happen,” he told theheart.org | Medscape Cardiology. “In New York, we’re not allowed to do elective cases but what’s considered elective is not so clearly defined. An AS [aortic stenosis] patient that had a syncopal episode 2 weeks ago, is that considered elective or is that semi-urgent? I think that’s one of the challenges and that’s where these partnerships would be useful.”

Other challenges include the need for regional partnerships to better align hospitals, which in the New York area means half a dozen large healthcare systems, and to coordinate care between hospital departments – all of which will be scheduling imaging and OR time for their own backlog of hernia, knee, or hip surgeries.

Finally, there’s the need for a lot of conversation with the patient and their family about returning to a hospital amid a deadly pandemic.

“I had a patient today and the daughter was very concerned about bringing her in,” Kodali said. “She’s in class IV heart failure but her [daughter’s] big concern was: who is she going to be exposed to when she gets the echo? What kind of protection is there for her? Is the tech wearing a mask?

“It’s not just the health care providers that have to have the comfort, but it’s the patients and their families who have to feel comfortable bringing their loved ones here for treatment,” he said. “Because everyone is concerned about the environment.”

As COVID-19 case levels plateau in some regions, 16 North American cardiovascular societies have released a framework for reintroducing cardiovascular services disrupted by the pandemic.

The consensus document outlines a phased approach to restarting invasive cardiovascular (CV) procedures and diagnostic tests that aims to reduce patient and health care provider exposure to the coronavirus and still provide essential care. It also emphasizes some of the ethical considerations in patient selection and the need for a collaborative approach.

“The key message in our document is we need a new unprecedented collaboration with public health officials so that we can carefully monitor the situation and we’re aware of what’s happening with the penetrance of the pandemic in the community, but they’re aware of the morbidity and mortality that’s occurring on our ever-growing waiting list,” lead author David A. Wood, MD, told theheart.org | Medscape Cardiology.

The recommendations were jointly published May 4 in the Canadian Journal of Cardiology , the Journal of the American College of Cardiology, and The Annals of Thoracic Surgery, and are endorsed by, among others, the American Heart Association, American College of Cardiology (ACC), and Canadian Cardiovascular Society.

The guidance comes as hospitals are facing revenue shortfalls because of canceled elective procedures and resource-intensive COVID-19 cases, prompting some healthcare systems to furlough, lay off, or even fire staff.

“It’s obvious that volumes are down between 40% and 60%,” said Wood, director of the cardiac catheterization laboratory at Vancouver General Hospital and professor of medicine at the University of British Columbia, Canada. “Part of that is that some areas have restricted case volumes totally appropriately and it’s partly because patients are very afraid of coming to the hospital and, unfortunately, are having bad events at home. And some are dying.”

The new report features a detailed table outlining three different response levels: reintroduction of some services (level 2); reintroduction of most services (level 1); and regular services (level 0). It covers a range of services from transthoracic echocardiography and exercise testing with imaging to care for acute coronary syndrome and ST-segment elevation myocardial infarction.

“We’ve learned that we can very quickly turn off the tap and go to doing only 10% of our normal volumes, whether that’s surgery, cath lab, EP, diagnostic tests,” Wood said. “It’s much more difficult to thoughtfully turn the tap part way back on or restart the engine … you don’t just go from 0 to 100 [mph]. You go from 0 to 30 to 60 then maybe to 80 [mph].”

The document also includes eight guiding principles such as:
 

• The expectation that response levels will be different between regions, and even within a given region.
• A “transparent collaborative plan” for COVID-19 testing and personal protective equipment (PPE) must be in place before restarting cases.
• A less invasive test or alternate imaging modality should be considered, if both tests have similar efficacy.
• In general, a minimally invasive procedure with a shorter length of stay is preferable, if both strategies have similar efficacy and safety.

Although previous reports on cath lab considerations during the pandemic or restarting elective surgeries peg various actions to specific thresholds or time intervals, the language here is noticeably and intentionally broad.

Instead of stating when cardiovascular services should resume, for example, the experts say it’s appropriate to put the guidance document into place if there’s a “sustained reduction” in the rate of new COVID-19 admissions and deaths in the relevant geographic region for a “prespecified time interval.”

As for when or how frequently patients and healthcare providers should be tested for COVID-19, the document encourages “routine screening of all patients prior to any cardiovascular procedure or test.”

Overly prescriptive language in previous documents wasn’t felt to be that helpful, whereas language like “selective” cases and “some” or “most” cardiovascular procedures gives clinicians, health systems, and policy makers flexibility when moving between response levels, Wood explained.

“Different regions might be at different levels based on principles of public health as far as the penetrance of the pandemic in that community, as well as how can you actually do the physical distancing in your hospital or ambulatory clinic.

Squamous cell carcinoma (SCC) has an estimated incidence of more than 2.5 million cases per year in the United States.¹ Its precursor lesion, actinic keratosis (AK), had an estimated prevalence of 39.5 million cases in the United States in 2004.² The dermatology clinic at the Providence VA Medical Center in Rhode Island exerts consistent efforts to treat both SCC and AK by prescribing topical 5-fluorouracil (5-FU) and lifestyle changes that include avoiding sun exposure, wearing protective clothing, and using effective sunscreen.³ A single course of topical 5-FU in veterans has been shown to decrease the risk for SCC by 74% during the year after treatment and also improve AK clearance rates.^4,5

Effectiveness of 5-FU for secondary prevention can be decreased by patient misunderstandings, such as applying 5-FU for too short a time or using the corticosteroid cream prematurely, as well as patient nonadherence due to expected adverse skin reactions to 5-FU.⁶ Education and reassurance before and during therapy maximize patient compliance but can be difficult to accomplish in clinics when time is in short supply. During standard 5-FU treatment at the Providence VA Medical Center, the provider prescribes 5-FU and posttherapy corticosteroid cream at a clinic visit after an informed consent process that includes reviewing with the patient a color handout depicting the expected adverse skin reaction. Patients who later experience severe inflammation and anxiety call the clinic and are overbooked as needed.

To address the practical obstacles to the patient experience with topical 5-FU therapy, we developed a group chemoprevention clinic based on the shared medical appointment (SMA) model. Shared medical appointments, during which multiple patients are scheduled at the same visit with 1 or more health care providers, promote patient risk reduction and guideline adherence in complex diseases, such as chronic heart failure and diabetes mellitus, through efficient resource use, improvement of access to care, and promotion of behavioral changes through group support.^7-13 To increase efficiency in the group chemoprevention clinic, we integrated dermatology nurses and nurse practitioners from the chronic care model into the group medical visits, which ran from September 2016 through March 2017. Because veterans could interact with peers undergoing the same treatment, we hypothesized that use of the cream in a group setting would provide positive reinforcement during the course of therapy, resulting in a positive treatment experience. We conducted a retrospective review of medical records of the patients involved in this pilot study to evaluate this model.

Methods

Institutional review board approval was obtained from the Providence VA Medical Center. Informed consent was waived because this study was a retrospective review of medical records.

Study Population
We offered participation in a group chemoprevention clinic based on the SMA model for patients of the dermatology clinic at the Providence VA Medical Center who were planning to start 5-FU in the fall of 2016. Patients were asked if they were interested in participating in a group clinic to receive their 5-FU treatment. Patients who were established dermatology patients within the Veterans Affairs system and had scheduled annual full-body skin examinations were included; patients were not excluded if they had a prior diagnosis of AK but had not been previously treated with 5-FU.

Design
Each SMA group consisted of 3 to 4 patients who met initially to receive the 5-FU medication and attend a 10-minute live presentation that included information on the dangers and causes of SCC and AK, treatment options, directions for using 5-FU, expected spectrum of side effects, and how to minimize the discomfort of treatment side effects. Patients had field treatment limited to areas with clinically apparent AKs on the face and ears. They were prescribed 5-FU cream 5% twice daily.

One physician, one nurse practitioner, and one registered nurse were present at each 1-hour clinic. Patients arrived and were checked in individually by the providers. At check-in, the provider handed the patient a printout of his/her current medication list and a pen to make any necessary corrections. This list was reviewed privately with the patient so the provider could reconcile the medication list and review the patient’s medical history and so the patient could provide informed consent. After, the patient had the opportunity to select a seat from chairs arranged in a circle. There was a live PowerPoint presentation given at the beginning of the clinic with a question-and-answer session immediately following that contained information about the disease and medication process. Clinicians assisted the patients with the initial application of 5-FU in the large group room, and each patient received a handout with information about AKs and a 40-g tube of the 5-FU cream.

This same group then met again 2 weeks later, at which time most patients were experiencing expected adverse skin reactions. At that time, there was a 10-minute live presentation that congratulated the patients on their success in the treatment process, reviewed what to expect in the following weeks, and reinforced the importance of future sun-protective practices. At each visit, photographs and feedback about the group setting were obtained in the large group room. After photographing and rating each patient’s skin reaction severity, the clinicians advised each patient either to continue the 5-FU medication for another week or to discontinue it and apply the triamcinolone cream 0.1% up to 4 times daily as needed for up to 7 days. Each patient received the prescription corticosteroid cream and a gift, courtesy of the VA Voluntary Service Program, of a 360-degree brimmed hat and sunscreen. Time for questions or concerns was available at both sessions.

Data Collection
We reviewed medical records via the Computerized Patient Record System, a nationally accessible electronic health record system, for all patients who participated in the SMA visits from September 2016 through March 2017. Any patient who attended the initial visit but declined therapy at that time was excluded.

Outcomes included attendance at both appointments, stated completion of 14 days of 5-FU treatment, and evidence of 5-FU use according to a validated numeric scale of skin reaction severity.¹⁴ We recorded telephone calls and other dermatology clinic and teledermatology appointments during the 3 weeks after the first appointment and the number of dermatology clinic appointments 6 months before and after the SMA for side effects related to 5-FU treatment. Feedback about treatment in the group setting was obtained at both visits.

Results

A total of 16 male patients attended the SMAs, and 14 attended both sessions. Of the 2 patients who were excluded from the study, 1 declined to be scheduled for the second group appointment, and the other was scheduled and confirmed but did not come for his appointment. The mean age was 72 years.

Of the 14 study patients who attended both sessions of the group clinic, 10 stated that they completed 2 weeks of 5-FU therapy, and the other 4 stated that they completed at least 11 days. Results of the validated scale used by clinicians during the second visit to grade the patients’ 5-FU reactions showed that all 14 patients demonstrated at least some expected adverse reactions (eTable). Eleven of 14 patients showed crusting and erosion; 13 showed grade 2 or higher erythema severity. One patient who stopped treatment after 11 days telephoned the dermatology clinic within 1 week of his second SMA. Another patient who stopped treatment after 11 days had a separate dermatology surgery clinic appointment within the 3-week period after starting 5-FU for a recent basal cell carcinoma excision. None of the 14 patients had a dermatology appointment scheduled within 6 months before or after for a 5-FU adverse reaction. One patient who completed the 14-day course was referred to teledermatology for insect bites within that period.

The verbal feedback about the group setting from patients who completed both appointments was uniformly positive, with specific appreciation for the normalization of the treatment process and opportunity to ask questions with their peers. At the conclusion of the second appointment, all of the patients reported an increased understanding of their condition and the importance of future sun-protective behaviors.

Comment

Shared medical appointments promote treatment adherence in patients with chronic heart failure and diabetes mellitus through efficient resource use, improvement of access to care, and promotion of behavioral change through group support.^7-13 Within the dermatology literature, SMAs are more profitable than regular clinic appointments.¹⁵ In SMAs designed to improve patient education for preoperative consultations for Mohs micrographic surgery, patient satisfaction reported in postvisit surveys was high, with 84.7% of 149 patients reporting they found the session useful, highlighting how SMAs have potential as practical alternatives to regular medical appointments.¹⁶ Similarly, the feedback about the group setting from our patients who completed both appointments was uniformly positive, with specific appreciation for the normalization of the treatment process and opportunity to ask questions with their peers.

The group setting—where patients were interacting with peers undergoing the same treatment—provided an encouraging environment during the course of 5-FU therapy, resulting in a positive treatment experience. Additionally, at the conclusion of the second visit, patients reported an increased understanding of their condition and the importance of future sun-protective behaviors, further demonstrating the impact of this pilot initiative.

The Veterans Affairs’ Current Procedural Terminology code for a group clinic is 99078. Veterans Affairs medical centers and private practices have different approaches to billing and compensation. As more accountable care organizations are formed, there may be a different mixture of ways for handling these SMAs.

Limitations
Our study is limited by the small sample size, selection bias, and self-reported measure of adherence. Adherence to 5-FU is excellent without group support, and without a control group, it is unclear how beneficial the group setting was for adherence.¹⁷ The presence of the expected skin reactions at the 2-week return visit cannot account for adherence during the interval between the visits, and this close follow-up may be responsible for the high adherence in this group setting. The major side effects with 5-FU are short-term. Nonetheless, longer-term follow-up would be helpful and a worthy future endeavor.

Veterans share a common bond of military service that may not be shared in a typical private practice setting, which may have facilitated success of this pilot study. We recommend group clinics be evaluated independently in private practices and other systems. However, despite these limitations, the patients in the SMAs demonstrated positive reactions to 5-FU therapy, suggesting the potential for utilizing group clinics as a practical alternative to regular medical appointments.

Conclusion

Our pilot group clinics for AK treatment and chemoprevention of SCC with 5-FU suggest that this model is well received. The group format, which demonstrated uniformly positive reactions to 5-FU therapy, shows promise in battling an epidemic of skin cancer that demands cost-effective interventions.

Squamous cell carcinoma (SCC) has an estimated incidence of more than 2.5 million cases per year in the United States.¹ Its precursor lesion, actinic keratosis (AK), had an estimated prevalence of 39.5 million cases in the United States in 2004.² The dermatology clinic at the Providence VA Medical Center in Rhode Island exerts consistent efforts to treat both SCC and AK by prescribing topical 5-fluorouracil (5-FU) and lifestyle changes that include avoiding sun exposure, wearing protective clothing, and using effective sunscreen.³ A single course of topical 5-FU in veterans has been shown to decrease the risk for SCC by 74% during the year after treatment and also improve AK clearance rates.^4,5

Effectiveness of 5-FU for secondary prevention can be decreased by patient misunderstandings, such as applying 5-FU for too short a time or using the corticosteroid cream prematurely, as well as patient nonadherence due to expected adverse skin reactions to 5-FU.⁶ Education and reassurance before and during therapy maximize patient compliance but can be difficult to accomplish in clinics when time is in short supply. During standard 5-FU treatment at the Providence VA Medical Center, the provider prescribes 5-FU and posttherapy corticosteroid cream at a clinic visit after an informed consent process that includes reviewing with the patient a color handout depicting the expected adverse skin reaction. Patients who later experience severe inflammation and anxiety call the clinic and are overbooked as needed.

To address the practical obstacles to the patient experience with topical 5-FU therapy, we developed a group chemoprevention clinic based on the shared medical appointment (SMA) model. Shared medical appointments, during which multiple patients are scheduled at the same visit with 1 or more health care providers, promote patient risk reduction and guideline adherence in complex diseases, such as chronic heart failure and diabetes mellitus, through efficient resource use, improvement of access to care, and promotion of behavioral changes through group support.^7-13 To increase efficiency in the group chemoprevention clinic, we integrated dermatology nurses and nurse practitioners from the chronic care model into the group medical visits, which ran from September 2016 through March 2017.

At check-in, the provider handed the patient a printout of his/her current medication list and a pen to make any necessary corrections. This list was reviewed privately with the patient so the provider could reconcile the medication list and review the patient’s medical history and so the patient could provide informed consent. After, the patient had the opportunity to select a seat from chairs arranged in a circle. There was a live PowerPoint presentation given at the beginning of the clinic with a question-and-answer session immediately following that contained information about the disease and medication process. Clinicians assisted the patients with the initial application of 5-FU in the large group room, and each patient received a handout with information about AKs and a 40-g tube of the 5-FU cream.

This same group then met again 2 weeks later, at which time most patients were experiencing expected adverse skin reactions. At that time, there was a 10-minute live presentation that congratulated the patients on their success in the treatment process, reviewed what to expect in the following weeks, and reinforced the importance of future sun-protective practices. At each visit, photographs and feedback about the group setting were obtained in the large group room. After photographing and rating each patient’s skin reaction severity, the clinicians advised each patient either to continue the 5-FU medication for another week or to discontinue it and apply the triamcinolone cream 0.1% up to 4 times daily as needed for up to 7 days. Each patient received the prescription corticosteroid cream and a gift, courtesy of the VA Voluntary Service Program, of a 360-degree brimmed hat and sunscreen. Time for questions or concerns was available at both sessions.

Data Collection
We reviewed medical records via the Computerized Patient Record System, a nationally accessible electronic health record system, for all patients who participated in the SMA visits from September 2016 through March 2017. Any patient who attended the initial visit but declined therapy at that time was excluded.

Outcomes included attendance at both appointments, stated completion of 14 days of 5-FU treatment, and evidence of 5-FU use according to a validated numeric scale of skin reaction severity.¹⁴ We recorded telephone calls and other dermatology clinic and teledermatology appointments during the 3 weeks after the first appointment and the number of dermatology clinic appointments 6 months before and after the SMA for side effects related to 5-FU treatment. Feedback about treatment in the group setting was obtained at both visits.

Results

A total of 16 male patients attended the SMAs, and 14 attended both sessions. Of the 2 patients who were excluded from the study, 1 declined to be scheduled for the second group appointment, and the other was scheduled and confirmed but did not come for his appointment. The mean age was 72 years.

Of the 14 study patients who attended both sessions of the group clinic, 10 stated that they completed 2 weeks of 5-FU therapy, and the other 4 stated that they completed at least 11 days. Results of the validated scale used by clinicians during the second visit to grade the patients’ 5-FU reactions showed that all 14 patients demonstrated at least some expected adverse reactions (eTable). Eleven of 14 patients showed crusting and erosion; 13 showed grade 2 or higher erythema severity. One patient who stopped treatment after 11 days telephoned the dermatology clinic within 1 week of his second SMA. Another patient who stopped treatment after 11 days had a separate dermatology surgery clinic appointment within the 3-week period after starting 5-FU for a recent basal cell carcinoma excision. None of the 14 patients had a dermatology appointment scheduled within 6 months before or after for a 5-FU adverse reaction. One patient who completed the 14-day course was referred to teledermatology for insect bites within that period.

The verbal feedback about the group setting from patients who completed both appointments was uniformly positive, with specific appreciation for the normalization of the treatment process and opportunity to ask questions with their peers. At the conclusion of the second appointment, all of the patients reported an increased understanding of their condition and the importance of future sun-protective behaviors.

Comment

Shared medical appointments promote treatment adherence in patients with chronic heart failure and diabetes mellitus through efficient resource use, improvement of access to care, and promotion of behavioral change through group support.^7-13 Within the dermatology literature, SMAs are more profitable than regular clinic appointments.¹⁵ In SMAs designed to improve patient education for preoperative consultations for Mohs micrographic surgery, patient satisfaction reported in postvisit surveys was high, with 84.7% of 149 patients reporting they found the session useful, highlighting how SMAs have potential as practical alternatives to regular medical appointments.¹⁶ Similarly, the feedback about the group setting from our patients who completed both appointments was uniformly positive, with specific appreciation for the normalization of the treatment process and opportunity to ask questions with their peers.

The group setting—where patients were interacting with peers undergoing the same treatment—provided an encouraging environment during the course of 5-FU therapy, resulting in a positive treatment experience. Additionally, at the conclusion of the second visit, patients reported an increased understanding of their condition and the importance of future sun-protective behaviors, further demonstrating the impact of this pilot initiative.

The Veterans Affairs’ Current Procedural Terminology code for a group clinic is 99078. Veterans Affairs medical centers and private practices have different approaches to billing and compensation. As more accountable care organizations are formed, there may be a different mixture of ways for handling these SMAs.

Limitations
Our study is limited by the small sample size, selection bias, and self-reported measure of adherence. Adherence to 5-FU is excellent without group support, and without a control group, it is unclear how beneficial the group setting was for adherence.¹⁷ The presence of the expected skin reactions at the 2-week return visit cannot account for adherence during the interval between the visits, and this close follow-up may be responsible for the high adherence in this group setting. The major side effects with 5-FU are short-term. Nonetheless, longer-term follow-up would be helpful and a worthy future endeavor.

Veterans share a common bond of military service that may not be shared in a typical private practice setting, which may have facilitated success of this pilot study. We recommend group clinics be evaluated independently in private practices and other systems. However, despite these limitations, the patients in the SMAs demonstrated positive reactions to 5-FU therapy, suggesting the potential for utilizing group clinics as a practical alternative to regular medical appointments.

Conclusion

Our pilot group clinics for AK treatment and chemoprevention of SCC with 5-FU suggest that this model is well received. The group format, which demonstrated uniformly positive reactions to 5-FU therapy, shows promise in battling an epidemic of skin cancer that demands cost-effective interventions.

Squamous cell carcinoma (SCC) has an estimated incidence of more than 2.5 million cases per year in the United States.¹ Its precursor lesion, actinic keratosis (AK), had an estimated prevalence of 39.5 million cases in the United States in 2004.² The dermatology clinic at the Providence VA Medical Center in Rhode Island exerts consistent efforts to treat both SCC and AK by prescribing topical 5-fluorouracil (5-FU) and lifestyle changes that include avoiding sun exposure, wearing protective clothing, and using effective sunscreen.³ A single course of topical 5-FU in veterans has been shown to decrease the risk for SCC by 74% during the year after treatment and also improve AK clearance rates.^4,5

Effectiveness of 5-FU for secondary prevention can be decreased by patient misunderstandings, such as applying 5-FU for too short a time or using the corticosteroid cream prematurely, as well as patient nonadherence due to expected adverse skin reactions to 5-FU.⁶ Education and reassurance before and during therapy maximize patient compliance but can be difficult to accomplish in clinics when time is in short supply. During standard 5-FU treatment at the Providence VA Medical Center, the provider prescribes 5-FU and posttherapy corticosteroid cream at a clinic visit after an informed consent process that includes reviewing with the patient a color handout depicting the expected adverse skin reaction. Patients who later experience severe inflammation and anxiety call the clinic and are overbooked as needed.

To address the practical obstacles to the patient experience with topical 5-FU therapy, we developed a group chemoprevention clinic based on the shared medical appointment (SMA) model. Shared medical appointments, during which multiple patients are scheduled at the same visit with 1 or more health care providers, promote patient risk reduction and guideline adherence in complex diseases, such as chronic heart failure and diabetes mellitus, through efficient resource use, improvement of access to care, and promotion of behavioral changes through group support.^7-13 To increase efficiency in the group chemoprevention clinic, we integrated dermatology nurses and nurse practitioners from the chronic care model into the group medical visits, which ran from September 2016 through March 2017. Because veterans could interact with peers undergoing the same treatment, we hypothesized that use of the cream in a group setting would provide positive reinforcement during the course of therapy, resulting in a positive treatment experience. We conducted a retrospective review of medical records of the patients involved in this pilot study to evaluate this model.

Methods

Institutional review board approval was obtained from the Providence VA Medical Center. Informed consent was waived because this study was a retrospective review of medical records.

Study Population
We offered participation in a group chemoprevention clinic based on the SMA model for patients of the dermatology clinic at the Providence VA Medical Center who were planning to start 5-FU in the fall of 2016. Patients were asked if they were interested in participating in a group clinic to receive their 5-FU treatment. Patients who were established dermatology patients within the Veterans Affairs system and had scheduled annual full-body skin examinations were included; patients were not excluded if they had a prior diagnosis of AK but had not been previously treated with 5-FU.

Design
Each SMA group consisted of 3 to 4 patients who met initially to receive the 5-FU medication and attend a 10-minute live presentation that included information on the dangers and causes of SCC and AK, treatment options, directions for using 5-FU, expected spectrum of side effects, and how to minimize the discomfort of treatment side effects. Patients had field treatment limited to areas with clinically apparent AKs on the face and ears. They were prescribed 5-FU cream 5% twice daily.

One physician, one nurse practitioner, and one registered nurse were present at each 1-hour clinic. Patients arrived and were checked in individually by the providers. At check-in, the provider handed the patient a printout of his/her current medication list and a pen to make any necessary corrections. This list was reviewed privately with the patient so the provider could reconcile the medication list and review the patient’s medical history and so the patient could provide informed consent. After, the patient had the opportunity to select a seat from chairs arranged in a circle. There was a live PowerPoint presentation given at the beginning of the clinic with a question-and-answer session immediately following that contained information about the disease and medication process. Clinicians assisted the patients with the initial application of 5-FU in the large group room, and each patient received a handout with information about AKs and a 40-g tube of the 5-FU cream.

This same group then met again 2 weeks later, at which time most patients were experiencing expected adverse skin reactions. At that time, there was a 10-minute live presentation that congratulated the patients on their success in the treatment process, reviewed what to expect in the following weeks, and reinforced the importance of future sun-protective practices. At each visit, photographs and feedback about the group setting were obtained in the large group room. After photographing and rating each patient’s skin reaction severity, the clinicians advised each patient either to continue the 5-FU medication for another week or to discontinue it and apply the triamcinolone cream 0.1% up to 4 times daily as needed for up to 7 days. Each patient received the prescription corticosteroid cream and a gift, courtesy of the VA Voluntary Service Program, of a 360-degree brimmed hat and sunscreen. Time for questions or concerns was available at both sessions.

Data Collection
We reviewed medical records via the Computerized Patient Record System, a nationally accessible electronic health record system, for all patients who participated in the SMA visits from September 2016 through March 2017. Any patient who attended the initial visit but declined therapy at that time was excluded.

Outcomes included attendance at both appointments, stated completion of 14 days of 5-FU treatment, and evidence of 5-FU use according to a validated numeric scale of skin reaction severity.¹⁴ We recorded telephone calls and other dermatology clinic and teledermatology appointments during the 3 weeks after the first appointment and the number of dermatology clinic appointments 6 months before and after the SMA for side effects related to 5-FU treatment. Feedback about treatment in the group setting was obtained at both visits.

Results

A total of 16 male patients attended the SMAs, and 14 attended both sessions. Of the 2 patients who were excluded from the study, 1 declined to be scheduled for the second group appointment, and the other was scheduled and confirmed but did not come for his appointment. The mean age was 72 years.

Of the 14 study patients who attended both sessions of the group clinic, 10 stated that they completed 2 weeks of 5-FU therapy, and the other 4 stated that they completed at least 11 days. Results of the validated scale used by clinicians during the second visit to grade the patients’ 5-FU reactions showed that all 14 patients demonstrated at least some expected adverse reactions (eTable). Eleven of 14 patients showed crusting and erosion; 13 showed grade 2 or higher erythema severity. One patient who stopped treatment after 11 days telephoned the dermatology clinic within 1 week of his second SMA. Another patient who stopped treatment after 11 days had a separate dermatology surgery clinic appointment within the 3-week period after starting 5-FU for a recent basal cell carcinoma excision. None of the 14 patients had a dermatology appointment scheduled within 6 months before or after for a 5-FU adverse reaction. One patient who completed the 14-day course was referred to teledermatology for insect bites within that period.

The verbal feedback about the group setting from patients who completed both appointments was uniformly positive, with specific appreciation for the normalization of the treatment process and opportunity to ask questions with their peers. At the conclusion of the second appointment, all of the patients reported an increased understanding of their condition and the importance of future sun-protective behaviors.

Epidemiology and Identification

Centruroides is a common genus of bark scorpions in the United States with at least 21 species considered to be medically important, including the closely related Centruroides exilicauda and Centruroides sculpturatus.¹ Scorpions can be recognized by a bulbous sac and pointed stinger at the end of a tail-like abdomen. They also have long lobsterlike pedipalps (pincers) for grasping their prey. Identifying characteristics for C exilicauda and C sculpturatus include a small, slender, yellow to light brown or tan body typically measuring 1.3 to 7.6 cm in length with a subaculear tooth or tubercle at the base of the stinger, a characteristic that is common to all Centruroides species (Figure).² Some variability in size has been shown, with smaller scorpions found in increased elevations and cooler temperatures.^1,3 Both C exilicauda and C sculpturatus are found in northern Mexico as well as the southwestern United States (eg, Arizona, New Mexico, Texas, California, Nevada).¹ They have a preference for residing in or around trees and often are found on the underside of bark, stones, or tables as well as inside shoes or small cracks and crevices. Scorpions typically sting in self-defense, and stings commonly occur when humans attempt to move tables, put on shoes, or walk barefoot in scorpion-infested areas. Most stings occur from the end of spring through the end summer, but many may go unreported.^1,4

The venom of the Centruroides genus includes peptides and proteins that play a fundamental role in toxic activity by impairing potassium, sodium, and calcium ion channels.^1,3 Toxins have been shown to be species specific, functioning either in capturing prey or deterring predators. Intraspecies variability in toxins has been demonstrated, which may complicate the production of adequate antivenin.³ Many have thought that C exilicauda Wood and C sculpturatus Ewing are the same species, and the names have been used synonymously in the past; however, genetic and biochemical studies of their venom components have shown that they are distinct species and that C sculpturatus is the more dangerous of the two.⁵ The median lethal dose 50% of C sculpturatus was found to be 22.7 μg in CD1 mice.⁶

Envenomation and Clinical Manifestations

Stings from C exilicauda and C sculpturatus have been shown to cause fatality in children more often than in adults.⁷ In the United States, Arizona has the highest frequency of serious symptoms of envenomation as well as the highest hospital and intensive care unit admission rates.⁶ Envenomation results in an immediate sharp burning pain followed by numbness.⁴ Wounds can produce some regional lymph node swelling, ecchymosis, paresthesia, and lymphangitis. More often than not, however, wounds have little to no inflammation and are characterized only by pain.⁴ The puncture wound is too small to be seen, and C exilicauda and C sculpturatus venom do not cause local tissue destruction, an important factor in distinguishing it from other scorpion envenomations.

More severe complications that may follow are caused by the neurotoxin released by Centruroides stings. The toxin components can increase the duration and amplitude of the neuronal action potential and enhance the release of neurotransmitters such as acetylcholine and norepinephrine.⁸ Stings can lead to cranial nerve dysfunction and somatic skeletal neuromuscular dysfunction as well as autonomic dysfunction, specifically salivation, fever, tongue and muscle fasciculations, opsoclonus, vomiting, bronchoconstriction, diaphoresis, nystagmus, blurred vision, slurred speech, hypertension, rhabdomyolysis, stridor, wheezing, aspiration, anaphylaxis, and tachycardia, leading to cardiac and respiratory compromise.^4,8 Some patients have experienced a decreased sense of smell or hearing and decreased fine motor movements.⁷ Although pancreatitis may occur with scorpion stings, it is not common for C exilicauda.⁹ Comorbidities such as cardiac disease and substance use disorders contribute to prolonged length of hospital stay and poor outcome.⁸

Treatment

Most Centruroides stings can be managed at home, but patients with more serious symptoms and children younger than 2 years should be taken to a hospital for treatment.⁷ If a patient reports only pain but shows no other signs of neurotoxicity, observation and pain relief with rest, ice, and elevation is appropriate management. Patients with severe manifestations have been treated with various combinations of lorazepam, glycopyrrolate, ipratropium bromide, and ondansetron, but the only treatment definitively shown to decrease time to symptom abatement is antivenin.⁷ It has been demonstrated that C exilicauda and C sculpturatus antivenin is relatively safe.⁷ Most patients, especially adults, do not die from C exilicauda and C sculpturatus stings; therefore, antivenin more commonly is symptom abating than it is lifesaving.¹⁰ In children, time to symptom resolution was decreased to fewer than 4 hours with antivenin, and there is a lower rate of inpatient admission when antivenin is administered.^4,10,11 There is a low incidence of anaphylactic reaction after antivenin, but there have been reported cases of self-limited serum sickness after antivenin use that generally can be managed with antihistamines and corticosteroids.^4,7

Acne keloidalis nuchae (AKN) is a chronic inflammatory disorder most commonly involving the occipital scalp and posterior neck characterized by the development of keloidlike papules, pustules, and plaques. If left untreated, this condition may progress to scarring alopecia. It primarily affects males of African descent, but it also may occur in females and in other ethnic groups. Although the exact underlying pathogenesis is unclear, close haircuts and chronic mechanical irritation to the posterior neck and scalp are known inciting factors. For this reason, AKN disproportionately affects active-duty military servicemembers who are held to strict grooming standards. The US Military maintains these grooming standards to ensure uniformity, self-discipline, and serviceability in operational settings.¹ Regulations dictate short tapered hair, particularly on the back of the neck, which can require weekly to biweekly haircuts to maintain.^1-5

First-line treatment of AKN is prevention by avoiding short haircuts and other forms of mechanical irritation.^1,6,7 However, there are considerable barriers to this strategy within the military due to uniform regulations as well as personal appearance and grooming standards. Early identification and treatment are of utmost importance in managing AKN in the military population to ensure reduction of morbidity, prevention of late-stage disease, and continued fitness for duty. This article reviews the clinical features, epidemiology, and treatments available for management of AKN, with a special focus on the active-duty military population.

Clinical Features and Epidemiology

Acne keloidalis nuchae is a chronic inflammatory disorder characterized by the development of keloidlike papules, pustules, and plaques on the posterior neck and occipital scalp.⁶ Also known as folliculitis keloidalis nuchae, AKN is seen primarily in men of African descent, though cases also have been reported in females and in a few other ethnic groups.^6,7 In black males, the AKN prevalence worldwide ranges from 0.5% to 13.6%. The male to female ratio is 20 to 1.⁷ Although the exact cause is unknown, AKN appears to develop from chronic irritation and inflammation following localized skin injury and/or trauma. Chronic irritation from close-shaved haircuts, tight-fitting shirt collars, caps, and helmets have all been implicated as considerable risk factors.^6-8

Symptoms generally develop hours to days following a close haircut and begin with the early formation of inflamed irritated papules and notable erythema.^6,7 These papules may become secondarily infected and develop into pustules and/or abscesses, especially in cases in which the affected individual continues to have the hair shaved. Continued use of shared razors increases the risk for secondary infection and also raises the concern for transmission of blood-borne pathogens, as AKN lesions are quick to bleed with minor trauma.⁷

Over time, chronic inflammation and continued trauma of the AKN papules leads to widespread fibrosis and scar formation, as the papules coalesce into larger plaques and nodules. If left untreated, these later stages of disease can progress to chronic scarring alopecia.⁶

Prevention

In the general population, first-line therapy of AKN is preventative. The goal is to break the cycle of chronic inflammation, thereby preventing the development of additional lesions and subsequent scarring.⁷ Patients should be encouraged to avoid frequent haircuts, close shaves, hats, helmets, and tight shirt collars.^6-8

A 2017 cross-sectional study by Adotama et al⁹ investigated recognition and management of AKN in predominantly black barbershops in an urban setting. Fifty barbers from barbershops in Oklahoma City, Oklahoma, were enrolled and interviewed for the study. Of these barbers, only 44% (22/50) were able to properly identify AKN from a photograph. Although the vast majority (94% [47/50]) were aware that razor use would aggravate the condition, only 46% (23/50) reported avoidance of cutting hair for clients with active AKN.⁹ This study, while limited by its small sample size, showed that many barbers may be unaware of AKN and therefore unknowingly contribute to the disease process by performing haircuts on actively inflamed scalps. For this reason, it is important to educate patients about their condition and strongly recommend lifestyle and hairstyle modifications in the management of their disease.

Acne keloidalis nuchae that is severe enough to interfere with the proper use and wear of military equipment (eg, Kevlar helmets) or maintenance of regulation grooming standards does not meet military admission standards.^10,11 However, mild undiagnosed cases may be overlooked during entrance physical examinations, while many servicemembers develop AKN after entering the military.¹⁰ For these individuals, long-term avoidance of haircuts is not a realistic or obtainable therapeutic option.

Treatment

Topical Therapy
Early mild to moderate cases of AKN—papules less than 3 mm, no nodules present—may be treated with potent topical steroids. Studies have shown 2-week alternating cycles of high-potency topical steroids (2 weeks of twice-daily application followed by 2 weeks without application) for 8 to 12 weeks to be effective in reducing AKN lesions.^8,12 Topical clindamycin also may be added and has demonstrated efficacy particularly when pustules are present.^7,8

Intralesional Steroids
For moderate cases of AKN—papules more than 3 mm, plaques, and nodules—intralesional steroid injections may be considered. Triamcinolone may be used at a dose of 5 to 40 mg/mL administered at 4-week intervals.⁷ More concentrated doses will produce faster responses but also carry the known risk of side effects such as hypopigmentation in darker-skinned individuals and skin atrophy.

Systemic Therapy
Systemic therapy with oral antibiotics may be warranted as an adjunct to mild to moderate cases of AKN or in cases with clear evidence of secondary infection. Long-term tetracycline antibiotics, such as minocycline and doxycycline, may be used concurrently with topical and/or intralesional steroids.^6,7 Their antibacterial and anti-inflammatory effects are useful in controlling secondary infections and reducing overall chronic inflammation.

When selecting an appropriate antibiotic for long-term use in active-duty military patients, it is important to consider their effects on duty status. Doxycycline is preferred for active-duty servicemembers because it is not duty limiting or medically disqualifying.^10,13-15 However, minocycline, is restricted for use in aviators and aircrew members due to the risk for central nervous system side effects, which may include light-headedness, dizziness, and vertigo.

UV Light Therapy
UV radiation has known anti-inflammatory, immunosuppressive, and antifibrotic effects and commonly is used in the treatment of many dermatologic conditions.¹⁶ Within the last decade, targeted UVB (tUVB) radiation has shown promise as an effective alternative therapy for AKN. In 2014, Okoye et al¹⁶ conducted a prospective, randomized, split-scalp study in 11 patients with AKN. Each patient underwent treatment with a tUVB device (with peaks at 303 and 313 nm) to a randomly selected side of the scalp 3 times weekly for 16 weeks. Significant reductions in lesion count were seen on the treated side after 8 (P=.03) and 16 weeks (P=.04), with no change noted on the control side. Aside from objective lesion counts, patients completed questionnaires (n=6) regarding their treatment outcomes. Notably, 83.3% (5/6) reported marked improvement in their condition. Aside from mild transient burning and erythema of the treated area, no serious side effects were reported.¹⁶

Targeted UVB phototherapy has limited utility in an operational setting due to accessibility and operational tempo. Phototherapy units typically are available only at commands in close proximity to large medical treatment facilities. Further, the vast majority of servicemembers have duty hours that are not amenable to multiple treatment sessions per week for several months. For servicemembers in administrative roles or serving in garrison or shore billets, tUVB or narrowband UV phototherapy may be viable treatment options.

Laser Therapy
Various lasers have been used to treat AKN, including the CO₂ laser, pulsed dye laser, 810-nm diode laser, and 1064-nm Nd:YAG laser.⁶ Kantor et al¹⁷ utilized a CO₂ laser with a focused beam for surgical excision of a late-stage AKN case as early as 1986. In these patients, it was demonstrated that focused CO₂ laser could be used to remove fibrotic lesions in an outpatient setting with only local anesthesia. Although only 8 patients were treated in this report, no relapses occurred.¹⁷

CO₂ laser evaporation using the unfocused beam setting with 130 to 150 J/cm² has been less successful, with relapses reported in multiple cases.⁶ Dragoni et al¹⁸ attempted treatment with a 595-nm pulsed dye laser with 6.5-J/cm² fluence and 0.5-millisecond pulse but faced similar results, with lesions returning within 1 month.

There have been numerous reports of clinical improvement of AKN with the use of the 1064-nm Nd:YAG laser.^6,19 Esmat et al¹⁹ treated 16 patients with a fluence of 35 to 45 J/cm² and pulse duration of 10 to 30 milliseconds adjusted to skin type and hair thickness. An overall 82% reduction in lesion count was observed after 5 treatment sessions. Biopsies following the treatment course demonstrated a significant reduction in papule and plaque count (P=.001 and P=.011, respectively), and no clinical recurrences were noted at 12 months posttreatment.¹⁹ Similarly, Woo et al²⁰ conducted a single-blinded, randomized, controlled trial to assess the efficacy of the Nd:YAG laser in combination with topical corticosteroid therapy vs topical corticosteroid monotherapy. Of the 20 patients treated, there was a statistically significant improvement in patients with papule-only AKN who received the laser and topical combination treatment (P=.031).²⁰

Laser therapy may be an available treatment option for military servicemembers stationed within close proximity to military treatment facilities, with the Nd:YAG laser typically having the widest availability. Although laser therapy may be effective in early stages of disease, servicemembers would have to be amenable to limitation of future hair growth in the treated areas.

Surgical Excision
Surgical excision may be considered for large, extensive, disfiguring, and/or refractory lesions. Excision is a safe and effective method to remove tender, inflamed, keloidlike masses. Techniques for excision include electrosurgical excision with secondary intention healing, excision of a horizontal ellipse involving the posterior hairline with either primary closure or secondary intention healing, and use of a semilunar tissue expander prior to excision and closure.⁶ Regardless of the technique, it is important to ensure that affected tissue is excised at a depth that includes the base of the hair follicles to prevent recurrence.²¹

Final Thoughts

Acne keloidalis nuchae is a chronic inflammatory disease that causes considerable morbidity and can lead to chronic infection, alopecia, and disfigurement of the occipital scalp and posterior neck. Although easily preventable through the avoidance of mechanical trauma, irritation, and frequent short haircuts, the active-duty military population is restricted in their preventive measures due to current grooming and uniform standards. In this population, early identification and treatment are necessary to manage the disease to reduce patient morbidity and ensure continued operational and medical readiness. Topical and intralesional steroids may be used in mild to moderate cases. Topical and/or systemic antibiotics may be added to the treatment regimen in cases of secondary bacterial infection. For more severe refractory cases, laser therapy or complete surgical excision may be warranted.

Acne keloidalis nuchae (AKN) is a chronic inflammatory disorder most commonly involving the occipital scalp and posterior neck characterized by the development of keloidlike papules, pustules, and plaques. If left untreated, this condition may progress to scarring alopecia. It primarily affects males of African descent, but it also may occur in females and in other ethnic groups. Although the exact underlying pathogenesis is unclear, close haircuts and chronic mechanical irritation to the posterior neck and scalp are known inciting factors. For this reason, AKN disproportionately affects active-duty military servicemembers who are held to strict grooming standards. The US Military maintains these grooming standards to ensure uniformity, self-discipline, and serviceability in operational settings.¹ Regulations dictate short tapered hair, particularly on the back of the neck, which can require weekly to biweekly haircuts to maintain.^1-5

First-line treatment of AKN is prevention by avoiding short haircuts and other forms of mechanical irritation.^1,6,7 However, there are considerable barriers to this strategy within the military due to uniform regulations as well as personal appearance and grooming standards. Early identification and treatment are of utmost importance in managing AKN in the military population to ensure reduction of morbidity, prevention of late-stage disease, and continued fitness for duty. This article reviews the clinical features, epidemiology, and treatments available for management of AKN, with a special focus on the active-duty military population.

Clinical Features and Epidemiology

Acne keloidalis nuchae is a chronic inflammatory disorder characterized by the development of keloidlike papules, pustules, and plaques on the posterior neck and occipital scalp.⁶ Also known as folliculitis keloidalis nuchae, AKN is seen primarily in men of African descent, though cases also have been reported in females and in a few other ethnic groups.^6,7 In black males, the AKN prevalence worldwide ranges from 0.5% to 13.6%. The male to female ratio is 20 to 1.⁷ Although the exact cause is unknown, AKN appears to develop from chronic irritation and inflammation following localized skin injury and/or trauma. Chronic irritation from close-shaved haircuts, tight-fitting shirt collars, caps, and helmets have all been implicated as considerable risk factors.^6-8

Symptoms generally develop hours to days following a close haircut and begin with the early formation of inflamed irritated papules and notable erythema.^6,7 These papules may become secondarily infected and develop into pustules and/or abscesses, especially in cases in which the affected individual continues to have the hair shaved. Continued use of shared razors increases the risk for secondary infection and also raises the concern for transmission of blood-borne pathogens, as AKN lesions are quick to bleed with minor trauma.⁷

Over time, chronic inflammation and continued trauma of the AKN papules leads to widespread fibrosis and scar formation, as the papules coalesce into larger plaques and nodules. If left untreated, these later stages of disease can progress to chronic scarring alopecia.⁶

Prevention

In the general population, first-line therapy of AKN is preventative. The goal is to break the cycle of chronic inflammation, thereby preventing the development of additional lesions and subsequent scarring.⁷ Patients should be encouraged to avoid frequent haircuts, close shaves, hats, helmets, and tight shirt collars.^6-8
