Infectious Diseases

More than half a million individuals are without housing (NWH) on any given night in the United States, as estimated by the US Department of Housing and Urban Development. ¹ Lack of hygiene, increased risk of infection and infestation due to living conditions, and barriers to health care put these individuals at increased risk for disease. ² Skin disease, including fungal infection and acne, are within the top 10 most prevalent diseases worldwide and can cause major psychologic impairment, yet dermatologic concerns and clinical outcomes in NWH patients have not been well characterized. ^2-5 Further, because this vulnerable demographic tends to be underinsured, they frequently present to the emergency department (ED) for management of disease. ^1,6 Survey of common concerns in NWH patients is of utility to consulting dermatologists and nondermatologist providers in the ED, who can familiarize themselves with management of diseases they are more likely to encounter. Few studies examine dermatologic conditions in the ED, and a thorough literature review indicates none have included homelessness as a variable. ^6,7 Additionally, comparison with a matched control group of patients with housing (WH) is limited. ^5,8 We present one of the largest comparisons of cutaneous disease in NWH vs WH patients in a single hospital system to elucidate the types of cutaneous disease that motivate patients to seek care, the location of skin disease, and differences in clinical care.

Methods

A retrospective medical record review of patients seen for an inclusive list of dermatologic diagnoses in the ED or while admitted at University Medical Center New Orleans, Louisiana (UMC), between January 1, 2018, and April 21, 2020, was conducted. This study was qualified as exempt from the institutional review board by Louisiana State University because it proposed zero risk to the patients and remained completely anonymous. Eight hundred forty-two total medical records were reviewed (NWH, 421; WH, 421)(Table 1). Patients with housing were matched based on self-identified race and ethnicity, sex, and age. Disease categories were constructed based on fundamental pathophysiology adapted from Dermatology⁹: infectious, noninfectious inflammatory, neoplasm, trauma and wounds, drug-related eruptions, vascular, pruritic, pigmented, bullous, neuropsychiatric, and other. Other included unspecified eruptions as well as miscellaneous lesions such as calluses. The current chief concern, anatomic location, and configuration were recorded, as well as biopsied lesions and outpatient referrals or inpatient consultations to dermatology or other specialties, including wound care, infectious disease, podiatry, and surgery. χ² analysis was used to analyze significance of cutaneous categories, body location, and referrals. Groups smaller than 5 defaulted to the Fisher exact test.

Results

The total diagnoses (including both chief concerns and secondary diagnoses) are shown in Table 2. Chief concerns were more frequently cutaneous or dermatologic for WH (NWH, 209; WH, 307; P<.001). In both groups, cutaneous infectious etiologies were more likely to be a patient’s presenting chief concern (58% NWH, P=.002; 42% WH, P<.001). Noninfectious inflammatory etiologies and pigmented lesions were more likely to be secondary diagnoses with an unrelated noncutaneous concern; noninfectious inflammatory etiologies were only 16% of the total cutaneous chief concerns (11% NWH, P=.04; 20% WH, P=.03), and no pigmented lesions were chief concerns.

Infection was the most common chief concern, though NWH patients presented with significantly more infectious concerns (NWH, 212; WH, 150; P<.001), particularly infestations (NWH, 33; WH, 8; P<.001) and bacterial etiologies (NWH, 127; WH, 100; P=.04). The majority of bacterial etiologies were either an abscess or cellulitis (NWH, 106; WH, 83), though infected chronic wounds were categorized as bacterial infection when treated definitively as such (eg, in the case of sacral ulcers causing osteomyelitis)(NWH, 21; WH, 17). Of note, infectious etiology was associated with intravenous drug use (IVDU) in both NWH and WH patients. Of 184 NWH who reported IVDU, 127 had an infectious diagnosis (P<.001). Similarly, 43 of 56 total WH patients who reported IVDU had an infectious diagnosis (P<.001). Infestation (within the infectious category) included scabies (NWH, 20; WH, 3) and insect or arthropod bites (NWH, 12; WH, 5). Two NWH patients also presented with swelling of the lower extremities and were subsequently diagnosed with maggot infestations. Fungal and viral etiologies were not significantly increased in either group; however, NWH did have a higher incidence of tinea pedis (NWH, 14; WH, 4; P=.03).

More neoplasms (NWH, 6; WH, 16; P=.03), noninfectious inflammatory eruptions (NWH, 48; WH, 85; P<.001), and cutaneous drug eruptions (NWH, 5; WH, 27; P<.001) were reported in WH patients. There was no significant difference in benign vs malignant neoplastic processes between groups. More noninfectious inflammatory eruptions in WH were specifically driven by a markedly increased incidence of follicular (NWH, 9; WH, 29; P<.001) and urticarial/erythematous (NWH, 3; WH, 13; P=.02) lesions. Follicular etiologies included acne (NWH, 1; WH, 6; P=.12), folliculitis (NWH, 5; WH, 2; P=.45), hidradenitis suppurativa (NWH, 2; WH, 11; P=.02), and pilonidal and sebaceous cysts (NWH, 1; WH, 10; P=.01). Allergic urticaria dominated the urticarial/erythematous category (NWH, 3; WH, 11; P=.06), though there were 2 WH presentations of diffuse erythema and skin peeling.

Another substantial proportion of cutaneous etiologies were due to trauma or chronic wounds. Significantly more traumatic injuries presented in NWH patients vs WH patients (36 vs 31; P=.04). Trauma included human or dog bites (NWH, 5; WH, 4), sunburns (NWH, 3; WH, 0), other burns (NWH, 11; WH, 13), abrasions and lacerations (NWH, 16; WH, 3; P=.004), and foreign bodies (NWH, 1; WH, 1). Wounds consisted of chronic wounds such as those due to diabetes mellitus (foot ulcers) or immobility (sacral ulcers); numbers were similar between groups.

Looking at location, NWH patients had more pathology on the feet (NWH, 62; WH, 39; P=.02), whereas WH patients had more disseminated multiregional concerns (NWH, 55; WH, 75; P=.05). No one body location was notably more likely to warrant a chief concern.

For clinical outcomes, more WH patients received a consultation of any kind (NWH, 171; WH, 217; P<.001), consultation to dermatology (NWH, 49; WH, 87; P<.001), and consultation to surgery (NWH, 64; WH, 110; P<.001)(Table 3 and Figure). More outpatient referrals to dermatology were made for WH patients (NWH, 61; WH, 82; P=.05). Notably, NWH patients presented for 80% fewer hospital follow-up appointments (NWH, 11; WH, 55; P<.001). It is essential to note that these findings were not affected by self-reported race or ethnicity. Results remained significant when broken into cohorts consisting of patients with and without skin of color.

Cutaneous Concerns in NWH Patients—Although cutaneous disease has been reported to disproportionately affect NWH patients,¹⁰ in our cohort, NWH patients had fewer cutaneous chief concerns than WH patients. However, without comparing with all patients entering the ED at UMC, we cannot make a statement on this claim. We do present a few reasons why NWH patients do not have more cutaneous concerns. First, they may wait to present with cutaneous disease until it becomes more severe (eg, until chronic wounds have progressed to infections). Second, as discussed in depth by Hollestein and Nijsten,³ dermatologic disease may be a major contributor to the overall count of disability-adjusted life years but may play a minor role in individual disability. Therefore, skin disease often is considered less important on an individual basis, despite substantial psychosocial burden, leading to further stigmatization of this vulnerable population and discouraged care-seeking behavior, particularly for noninfectious inflammatory eruptions, which were notably more present in WH individuals. Third, fewer dermatologic lesions were reported on NWH patients, which may explain why all 3 WH pigmented lesions were diagnosed after presentation with a noncutaneous concern (eg, headache, anemia, nausea).

Infectious Cutaneous Diagnoses—The increased presentation of infectious etiologies, especially bacterial, is linked to the increased numbers of IVDUs reported in NWH individuals as well as increased exposure and decreased access to basic hygienic supplies. Intravenous drug use acted as an effect modifier of infectious etiology diagnoses, playing a major role in both NWH and WH cohorts. Although Black and Hispanic individuals as well as individuals with low socioeconomic status have increased proportions of skin cancer, there are inadequate data on the prevalence in NWH individuals.⁴ We found no increase in malignant dermatologic processes in NWH individuals; however, this may be secondary to inadequate screening with a total body skin examination.

Clinical Workup of NWH Patients—Because most NWH individuals present to the ED to receive care, their care compared with WH patients should be considered. In this cohort, WH patients received a less extensive clinical workup. They received almost half as many dermatologic consultations and fewer outpatient referrals to dermatology. Major communication barriers may affect NWH presentation to follow-up, which was drastically lower than WH individuals, as scheduling typically occurs well after discharge from the ED or inpatient unit. We suggest a few alterations to improve dermatologic care for NWH individuals:

• Consider inpatient consultation for serious dermatologic conditions—even if chronic—to improve disease control, considering that many barriers inhibit follow-up in clinic.

• Involve outreach teams, such as the Assertive Community Treatment teams, that assist individuals by delivering medicine for psychiatric disorders, conducting total-body skin examinations, assisting with wound care, providing basic skin barrier creams or medicaments, and carrying information regarding outpatient follow-up.

• Educate ED providers on the most common skin concerns, especially those that fall within the noninfectious inflammatory category, such as hidradenitis suppurativa, which could easily be misdiagnosed as an abscess.

Future Directions—Owing to limitations of a retrospective cohort study, we present several opportunities for further research on this vulnerable population. The severity of disease, especially infectious etiologies, should be graded to determine if NWH patients truly present later in the disease course. The duration and quality of housing for NWH patients could be categorized based on living conditions (eg, on the street vs in a shelter). Although the findings of our NWH cohort presenting to the ED at UMC provide helpful insight into dermatologic disease, these findings may be disparate from those conducted at other locations in the United States. University Medical Center provides care to mostly subsidized insurance plans in a racially diverse community. Improved outcomes for the NWH individuals living in New Orleans start with obtaining a greater understanding of their diseases and where disparities exist that can be bridged with better care.

Dedicator of cytokinesis 8 (DOCK8 ) deficiency is the major cause of autosomal-recessive hyper-IgEsyndrome. ¹ Characteristic clinical features including eosinophilia, eczema, and recurrent Staphylococcus aureus cutaneous and respiratory tract infections are common in DOCK8 deficiency, similar to the autosomal-dominant form of hyper-IgE syndrome that is due to defi c iency of signal transducer and activation of transcription 3 (STAT-3 ). ¹ In addition, patients with DOCK8 deficiency are particularly susceptible to asthma; food allergies; lymphomas; and severe cutaneous viral infections, including herpes simplex virus (HSV), molluscum contagiosum, varicella-zoster virus, and human papillomavirus. Since the discovery of the DOCK8 gene in 2009, various studies have sought to elucidate the mechanistic contribution of DOCK8 to the dermatologic immune environment. ² Although cutaneous viral infections such as those caused by HSV typically are short lived and self-limiting in immunocompetent hosts, they have proven to be severe and recalcitrant in the setting of DOCK8 deficiency. ¹ Herein, we report the case of a 32-month-old girl with homozygous DOCK8 deficiency who developed acyclovir-resistant cutaneous HSV. 

Case Report

A 32-month-old girl presented with an approximately 2-cm linear erosion along the left posterior auricular sulcus at month 9 of a hospital stay for recurrent infections. Her medical history was notable for multiple upper respiratory tract infections, diffuse eczema, and food allergies. She had presented to an outside hospital at 14 months of age with herpetic gingivostomatitis and eczema herpeticum that was successfully treated with acyclovir. She was readmitted at 20 months of age due to Pneumocystis jiroveci pneumonia, pancytopenia, and disseminated histoplasmosis. Prophylactic oral acyclovir (20 mg/kg twice daily) was started, given her history of HSV infection. Because of recurrent infections, she underwent an immunodeficiency workup. Whole exome sequencing analysis revealed a homozygous deletion c.(528+1_529−1)_(1516+1_1517−1)del in DOCK8 gene–affecting exons 5 to 13. The patient was transferred to our hospital for continued care and as a potential candidate for bone marrow transplant following resolution of the disseminated histoplasmosis infection.

During her hospitalization at the current presentation, she was noted to have a 2-cm linear erosion along the left posterior auricular sulcus. Initial wound care with bacitracin ointment was applied to the area while specimens were obtained and empiric oral acyclovir therapy was initiated (20 mg/kg 4 times daily [QID]), given a clinical impression consistent with cutaneous HSV infection despite acyclovir prophylaxis. Direct immunofluorescence and viral cultures were positive for HSV-1, while bacterial cultures grew methicillin-susceptible S aureus. Cephalexin and mupirocin ointment were started, and acyclovir was continued. After 2 weeks of therapy, there was no visible change in the wound; cultures were repeated, again showing the wound contained HSV. Bacterial cultures this time grew Pseudomonas putida, and the antibiotic regimen was transitioned to cefepime.

After no response to the continued course of therapeutic acyclovir, HSV cultures were sent to the Centers for Disease Control and Prevention for resistance testing, and biopsy of the lesion was performed by the otolaryngology service to rule out malignancy and potential alternative diagnoses. Histopathology showed only reactive inflammation without visible microorganisms on tissue HSV-1/HSV-2 immunostain; however, tissue viral culture was positive for HSV-1. The patient was transitioned back to acyclovir (intravenous [IV] 20 mg/kg QID) with the addition of empiric foscarnet (IV 40 mg/kg 3 times daily) given the worsening appearance of the lesion.  The HSV acyclovir resistance test results from the Centers for Disease Control and Prevention returned soon after and were positive for resistance (median infectious dose, 3.29 µg/L [reference interval, sensitive <2.00 µg/L; resistant >1.90 µg/L]). The patient completed a 21-day course of combination foscarnet and acyclovir therapy, during which time the lesion showed notable improvement and healing. The patient was continued on prophylactic acyclovir (IV 20 mg/kg QID). Unfortunately, the patient eventually died due to complications related to pneumonia.

Comment

Infection in Patients With DOCK8 Deficiency—The gene DOCK8 has emerged as playing a central role in both innate and adaptive immunity, as it is expressed primarily in immune cells and serves as a mediator of numerous processes, including immune synapse formation, cell signaling and trafficking, antibody and cytokine production, and lymphocyte memory.³ Cells that are critical for combating cutaneous viral infections, including skin-resident memory T cells and natural killer cells, are defective, which leads to a severely immunocompromised state in DOCK8-deficient patients with a particular susceptibility to infectious and inflammatory dermatologic disease.⁴ 

Herpes simplex virus infection commonly is seen in DOCK8 deficiency, with retrospective analysis of a DOCK8-deficient cohort revealing HSV infection in approximately 38% of patients.⁵ Prophylactic acyclovir is essential for DOCK8-deficient individuals with a history of HSV infection given the tendency of the virus to reactivate.⁶ However, despite prophylaxis, our patient developed an HSV-positive posterior auricular erosion that continued to progress even after increase of the acyclovir dose. Acyclovir resistance testing of the HSV isolated from the wound was positive, confirming the clinical suspicion of the presence of acyclovir-resistant HSV infection.

Acyclovir-Resistant HSV—Acyclovir-resistant HSV in immunosuppressed individuals was first noted in 1982, and most cases since then have occurred in the setting of AIDS and in organ transplant recipients.⁶ Few reports of acyclovir-resistant HSV in DOCK8 deficiency exist, and to our knowledge, our patient is the youngest DOCK8-deficient individual to be documented with acyclovir-resistant HSV infection.^1,7-15 We identified relevant cases from the PubMed and EMBASE databases using the search terms DOCK8 deficiency and acyclovir and DOCK8 deficiency and herpes. The eTable lists other reported cases of acyclovir-resistant HSV in DOCK8-deficient patients. The majority of cases involved school-aged females. Lesion types varied and included herpes labialis, eczema herpeticum, and blepharoconjunctivitis. Escalation of therapy and resolution of the lesion was seen in some cases with administration of subcutaneous pegylated interferon alfa-2b.

Treatment Alternatives—Acyclovir competitively inhibits viral DNA polymerase by incorporating into elongating viral DNA strands and halting chain synthesis. Acyclovir requires triphosphorylation for activation, and viral thymidine kinase is responsible for the first phosphorylation event. Ninety-five percent of cases of acyclovir resistance are secondary to mutations in viral thymidine kinase. Foscarnet also inhibits viral DNA polymerase but does so directly without the need to be phosphorylated first.⁶ For this reason, foscarnet often is the drug of choice in the treatment of acyclovir-resistant HSV, as evidenced in our patient. However, foscarnet-resistant HSV strains may develop from mutations in the DNA polymerase gene.

Cidofovir is a nucleotide analogue that requires phosphorylation by host, as opposed to viral, kinases for antiviral activity. Intravenous and topical formulations of cidofovir have proven effective in the treatment of acyclovir- and foscarnet-resistant HSV lesions.⁶ Cidofovir also can be applied intralesionally, a method that provides targeted therapy and minimizes cidofovir-associated nephrotoxicity.¹² Reports of systemic interferon alfa therapy for acyclovir-resistant HSV also exist. A study found IFN-⍺ production by peripheral blood mononuclear cells in DOCK8-deficient individuals to be significantly reduced relative to controls (P<.05).⁷ There has been complete resolution of acyclovir-resistant HSV lesions with subcutaneous pegylated interferon alfa-2b injections in several DOCK8-deficient patients.^7-9

The need for escalating therapy in DOCK8-deficient individuals with acyclovir-resistant HSV infection underscores the essential role of DOCK8 in dermatologic immunity. Our case demonstrates that a high degree of suspicion for cutaneous HSV infection should be adopted in DOCK8-deficient patients of any age, regardless of acyclovir prophylaxis. Viral culture in addition to bacterial cultures should be performed early in patients with cutaneous erosions, and the threshold for HSV resistance testing should be low to minimize morbidity associated with these infections. Early resistance testing in our case could have prevented prolongation of infection and likely eliminated the need for a biopsy.

Conclusion

DOCK8 deficiency presents a unique challenge to dermatologists and other health care providers given the susceptibility of affected individuals to developing a reservoir of severe and potentially resistant viral cutaneous infections. Prophylactic acyclovir may not be sufficient for HSV suppression, even in the youngest of patients, and suspicion for resistance should be high to avoid delays in adequate treatment.

Fear of antibiotic overuse and frustration with physicians who prescribe them too freely are key sentiments expressed by women with recurrent urinary tract infections (rUTIs), according to findings from a study involving six focus groups.

“Here in our female pelvic medicine reconstructive urology clinic at Cedars-Sinai and at UCLA, we see many women who are referred for evaluation of rUTIs who are very frustrated with their care,” Victoria Scott, MD, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

“So with these focus groups, we saw an opportunity to explore why women are so frustrated and to try and improve the care delivered,” she added.

Findings from the study were published online Sept. 1 in The Journal of Urology.

“There is a need for physicians to modify management strategies ... and to devote more research efforts to improving nonantibiotic options for the prevention and treatment of recurrent urinary tract infections, as well as management strategies that better empower patients,” the authors wrote.
 

Six focus groups

Four or five participants were included in each of the six focus groups – a total of 29 women. All participants reported a history of symptomatic, culture-proven UTI episodes. They had experienced two or more infections in 6 months or three or more infections within 1 year. Women were predominantly White. Most were employed part- or full-time and held a college degree.

From a qualitative analysis of all focus group transcripts, two main themes emerged:

• The negative impact of taking antibiotics for the prevention and treatment of rUTIs.
• Resentment of the medical profession for the way it managed rUTIs.

The researchers found that participants had a good understanding of the deleterious effects from inappropriate antibiotic use, largely gleaned from media sources and the Internet. “Numerous women stated that they had reached such a level of concern about antibiotics that they would resist taking them for prevention or treatment of infections,” Dr. Scott and colleagues pointed out.

These concerns centered around the risk of developing resistance to antibiotics and the ill effects that antibiotics can have on the gastrointestinal and genitourinary microbiomes. Several women reported that they had developed Clostridium difficile infections after taking antibiotics; one of the patients required hospitalization for the infection.

Women also reported concerns that they had been given an antibiotic needlessly for symptoms that might have been caused by a genitourinary condition other than a UTI. They also reported feeling resentful toward practitioners, particularly if they felt the practitioner was overprescribing antibiotics. Some had resorted to consultations with alternative practitioners, such as herbalists. “A second concern discussed by participants was the feeling of being ignored by physicians,” the authors observed.

In this regard, the women felt that their physicians underestimated the burden that rUTIs had on their lives and the detrimental effect that repeated infections had on their relationships, work, and overall quality of life. “These perceptions led to a prevalent mistrust of physicians,” the investigators wrote. This prompted many women to insist that the medical community devote more effort to the development of nonantibiotic options for the prevention and treatment of UTIs.
 

Improved management strategies

Asked how physicians might improve their management of rUTIs, Dr. Scott shared a number of suggestions. Cardinal rule No. 1: Have the patient undergo a urinalysis to make sure she does have a UTI. “There is a subset of patients among women with rUTIs who come in with a diagnosis of an rUTI but who really have not had documentation of more than one positive urine culture,” Dr. Scott noted. Such a history suggests that they do not have an rUTI.

It’s imperative that physicians rule out commonly misdiagnosed disorders, such as overactive bladder, as a cause of the patient’s symptoms. Symptoms of overactive bladder and rUTIs often overlap. While waiting for results from the urinalysis to confirm or rule out a UTI, young and healthy women may be prescribed a nonsteroidal anti-inflammatory drug (NSAID), such as naproxen, which can help ameliorate symptoms.

Because UTIs are frequently self-limiting, Dr. Scott and others have found that for young, otherwise healthy women, NSAIDs alone can often resolve symptoms of the UTI without use of an antibiotic. For relatively severe symptoms, a urinary analgesic, such as phenazopyridine (Pyridium), may soothe the lining of the urinary tract and relieve pain. Cystex is an over-the-counter urinary analgesic that women can procure themselves, Dr. Scott added.

If an antibiotic is indicated, those most commonly prescribed for a single episode of acute cystitis are nitrofurantoin and sulfamethoxazole plus trimethoprim (Bactrim). For recurrent UTIs, “patients are a bit more complicated,” Dr. Scott admitted. “I think the best practice is to look back at a woman’s prior urine culture and select an antibiotic that showed good sensitivity in the last positive urine test,” she said.

Prevention starts with behavioral strategies, such as voiding after sexual intercourse and wiping from front to back following urination to avoid introducing fecal bacteria into the urethra. Evidence suggests that premenopausal women who drink at least 1.5 L of water a day have significantly fewer UTI episodes, Dr. Scott noted. There is also “pretty good” evidence that cranberry supplements (not juice) can prevent rUTIs. Use of cranberry supplements is supported by the American Urological Association (conditional recommendation; evidence level of grade C).

For peri- and postmenopausal women, vaginal estrogen may be effective. It’s use for UTI prevention is well supported by the literature. Although not as well supported by evidence, some women find that a supplement such as D-mannose may prevent or treat UTIs by causing bacteria to bind to it rather than to the bladder wall. Probiotics are another possibility, she noted. Empathy can’t hurt, she added.

“A common theme among satisfied women was the sentiment that their physicians understood their problems and had a system in place to allow rapid diagnosis and treatment for UTI episodes,” the authors emphasized.

“[Such attitudes] highlight the need to investigate each patient’s experience and perceptions to allow for shared decision making regarding the management of rUTIs,” they wrote.
 

Further commentary

Asked to comment on the findings, editorialist Michelle Van Kuiken, MD, assistant professor of urology, University of California, San Francisco, acknowledged that there is not a lot of good evidence to support many of the strategies recommended by the American Urological Association to prevent and treat rUTIs, but she often follows these recommendations anyway. “The one statement in the guidelines that is the most supported by evidence is the use of cranberry supplements, and I do routinely recommended daily use of some form of concentrated cranberry supplements for all of my patients with rUTIs,” she said in an interview.

Dr. Van Kuiken said that vaginal estrogen is a very good option for all postmenopausal women who suffer from rUTIs and that there is growing acceptance of its use for this and other indications. There is some evidence to support D-mannose as well, although it’s not that robust, she acknowledged.

She said the evidence supporting the use of probiotics for this indication is very thin. She does not routinely recommend them for rUTIs, although they are not inherently harmful. “I think for a lot of women who have rUTIs, it can be pretty debilitating and upsetting for them – it can impact travel plans, work, and social events,” Dr. Van Kuiken said.

“Until we develop better diagnostic and therapeutic strategies, validating women’s experiences and concerns with rUTI while limiting unnecessary antibiotics remains our best option,” she wrote.

Dr. Scott and Dr. Van Kuiken have disclosed no relevant financial relationships.

The researchers found that participants had a good understanding of the deleterious effects from inappropriate antibiotic use, largely gleaned from media sources and the Internet. “Numerous women stated that they had reached such a level of concern about antibiotics that they would resist taking them for prevention or treatment of infections,” Dr. Scott and colleagues pointed out.

These concerns centered around the risk of developing resistance to antibiotics and the ill effects that antibiotics can have on the gastrointestinal and genitourinary microbiomes. Several women reported that they had developed Clostridium difficile infections after taking antibiotics; one of the patients required hospitalization for the infection.

Women also reported concerns that they had been given an antibiotic needlessly for symptoms that might have been caused by a genitourinary condition other than a UTI. They also reported feeling resentful toward practitioners, particularly if they felt the practitioner was overprescribing antibiotics. Some had resorted to consultations with alternative practitioners, such as herbalists. “A second concern discussed by participants was the feeling of being ignored by physicians,” the authors observed.

In this regard, the women felt that their physicians underestimated the burden that rUTIs had on their lives and the detrimental effect that repeated infections had on their relationships, work, and overall quality of life. “These perceptions led to a prevalent mistrust of physicians,” the investigators wrote. This prompted many women to insist that the medical community devote more effort to the development of nonantibiotic options for the prevention and treatment of UTIs.
 

Improved management strategies

Asked how physicians might improve their management of rUTIs, Dr. Scott shared a number of suggestions. Cardinal rule No. 1: Have the patient undergo a urinalysis to make sure she does have a UTI. “There is a subset of patients among women with rUTIs who come in with a diagnosis of an rUTI but who really have not had documentation of more than one positive urine culture,” Dr. Scott noted. Such a history suggests that they do not have an rUTI.

It’s imperative that physicians rule out commonly misdiagnosed disorders, such as overactive bladder, as a cause of the patient’s symptoms. Symptoms of overactive bladder and rUTIs often overlap. While waiting for results from the urinalysis to confirm or rule out a UTI, young and healthy women may be prescribed a nonsteroidal anti-inflammatory drug (NSAID), such as naproxen, which can help ameliorate symptoms.

Because UTIs are frequently self-limiting, Dr. Scott and others have found that for young, otherwise healthy women, NSAIDs alone can often resolve symptoms of the UTI without use of an antibiotic. For relatively severe symptoms, a urinary analgesic, such as phenazopyridine (Pyridium), may soothe the lining of the urinary tract and relieve pain. Cystex is an over-the-counter urinary analgesic that women can procure themselves, Dr. Scott added.

If an antibiotic is indicated, those most commonly prescribed for a single episode of acute cystitis are nitrofurantoin and sulfamethoxazole plus trimethoprim (Bactrim). For recurrent UTIs, “patients are a bit more complicated,” Dr. Scott admitted. “I think the best practice is to look back at a woman’s prior urine culture and select an antibiotic that showed good sensitivity in the last positive urine test,” she said.

Prevention starts with behavioral strategies, such as voiding after sexual intercourse and wiping from front to back following urination to avoid introducing fecal bacteria into the urethra. Evidence suggests that premenopausal women who drink at least 1.5 L of water a day have significantly fewer UTI episodes, Dr. Scott noted. There is also “pretty good” evidence that cranberry supplements (not juice) can prevent rUTIs. Use of cranberry supplements is supported by the American Urological Association (conditional recommendation; evidence level of grade C).

For peri- and postmenopausal women, vaginal estrogen may be effective. It’s use for UTI prevention is well supported by the literature. Although not as well supported by evidence, some women find that a supplement such as D-mannose may prevent or treat UTIs by causing bacteria to bind to it rather than to the bladder wall. Probiotics are another possibility, she noted. Empathy can’t hurt, she added.

“A common theme among satisfied women was the sentiment that their physicians understood their problems and had a system in place to allow rapid diagnosis and treatment for UTI episodes,” the authors emphasized.

“[Such attitudes] highlight the need to investigate each patient’s experience and perceptions to allow for shared decision making regarding the management of rUTIs,” they wrote.
 

Further commentary

Asked to comment on the findings, editorialist Michelle Van Kuiken, MD, assistant professor of urology, University of California, San Francisco, acknowledged that there is not a lot of good evidence to support many of the strategies recommended by the American Urological Association to prevent and treat rUTIs, but she often follows these recommendations anyway. “The one statement in the guidelines that is the most supported by evidence is the use of cranberry supplements, and I do routinely recommended daily use of some form of concentrated cranberry supplements for all of my patients with rUTIs,” she said in an interview.

Dr. Van Kuiken said that vaginal estrogen is a very good option for all postmenopausal women who suffer from rUTIs and that there is growing acceptance of its use for this and other indications. There is some evidence to support D-mannose as well, although it’s not that robust, she acknowledged.

She said the evidence supporting the use of probiotics for this indication is very thin. She does not routinely recommend them for rUTIs, although they are not inherently harmful. “I think for a lot of women who have rUTIs, it can be pretty debilitating and upsetting for them – it can impact travel plans, work, and social events,” Dr. Van Kuiken said.

“Until we develop better diagnostic and therapeutic strategies, validating women’s experiences and concerns with rUTI while limiting unnecessary antibiotics remains our best option,” she wrote.

Dr. Scott and Dr. Van Kuiken have disclosed no relevant financial relationships.

Fear of antibiotic overuse and frustration with physicians who prescribe them too freely are key sentiments expressed by women with recurrent urinary tract infections (rUTIs), according to findings from a study involving six focus groups.

“Here in our female pelvic medicine reconstructive urology clinic at Cedars-Sinai and at UCLA, we see many women who are referred for evaluation of rUTIs who are very frustrated with their care,” Victoria Scott, MD, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

“So with these focus groups, we saw an opportunity to explore why women are so frustrated and to try and improve the care delivered,” she added.

Findings from the study were published online Sept. 1 in The Journal of Urology.

“There is a need for physicians to modify management strategies ... and to devote more research efforts to improving nonantibiotic options for the prevention and treatment of recurrent urinary tract infections, as well as management strategies that better empower patients,” the authors wrote.
 

Six focus groups

Four or five participants were included in each of the six focus groups – a total of 29 women. All participants reported a history of symptomatic, culture-proven UTI episodes. They had experienced two or more infections in 6 months or three or more infections within 1 year. Women were predominantly White. Most were employed part- or full-time and held a college degree.

From a qualitative analysis of all focus group transcripts, two main themes emerged:

• The negative impact of taking antibiotics for the prevention and treatment of rUTIs.
• Resentment of the medical profession for the way it managed rUTIs.

The researchers found that participants had a good understanding of the deleterious effects from inappropriate antibiotic use, largely gleaned from media sources and the Internet. “Numerous women stated that they had reached such a level of concern about antibiotics that they would resist taking them for prevention or treatment of infections,” Dr. Scott and colleagues pointed out.

A secondary consequence of public health measures to prevent the spread of SARS-CoV-2 included a concurrent reduction in risk for children to acquire and spread other respiratory viral infectious diseases. In the Rochester, N.Y., area, we had an ongoing prospective study in primary care pediatric practices that afforded an opportunity to assess the effect of the pandemic control measures on all infectious disease illness visits in young children. Specifically, in children aged 6-36 months old, our study was in place when the pandemic began with a primary objective to evaluate the changing epidemiology of acute otitis media (AOM) and nasopharyngeal colonization by potential bacterial respiratory pathogens in community-based primary care pediatric practices. As the public health measures mandated by New York State Department of Health were implemented, we prospectively quantified their effect on physician-diagnosed infectious disease illness visits. The incidence of infectious disease visits by a cohort of young children during the COVID-19 pandemic period March 15, 2020, through Dec. 31, 2020, was compared with the same time frame in the preceding year, 2019.¹

Recommendations of the New York State Department of Health for public health, changes in school and day care attendance, and clinical practice during the study time frame

On March 7, 2020, a state of emergency was declared in New York because of the COVID-19 pandemic. All schools were required to close. A mandated order for public use of masks in adults and children more than 2 years of age was enacted. In the Finger Lakes region of Upstate New York, where the two primary care pediatric practices reside, complete lockdown was partially lifted on May 15, 2020, and further lifted on June 26, 2020. Almost all regional school districts opened to at least hybrid learning models for all students starting Sept. 8, 2020. On March 6, 2020, video telehealth and telephone call visits were introduced as routine practice. Well-child visits were limited to those less than 2 years of age, then gradually expanded to all ages by late May 2020. During the “stay at home” phase of the New York State lockdown, day care services were considered an essential business. Day care child density was limited. All children less than 2 years old were required to wear a mask while in the facility. Upon arrival, children with any respiratory symptoms or fever were excluded. For the school year commencing September 2020, almost all regional school districts opened to virtual, hybrid, or in-person learning models. Exclusion occurred similar to that of the day care facilities.

Incidence of respiratory infectious disease illnesses

Clinical diagnoses and healthy visits of 144 children from March 15 to Dec. 31, 2020 (beginning of the pandemic) were compared to 215 children during the same months in 2019 (prepandemic). Pediatric SARS-CoV-2 positivity rates trended up alongside community spread. Pediatric practice positivity rates rose from 1.9% in October 2020 to 19% in December 2020.

The table shows the incidence of significantly different infectious disease illness visits in the two study cohorts.

Change in care practices

In the prepandemic period, virtual visits, leading to a diagnosis and treatment and referring children to an urgent care or hospital emergency department during regular office hours were rare. During the pandemic, this changed. Significantly increased use of telemedicine visits (P < .0001) and significantly decreased office and urgent care visits (P < .0001) occurred during the pandemic. Telehealth visits peaked the week of April 12, 2020, at 45% of all pediatric visits. In-person illness visits gradually returned to year-to-year volumes in August-September 2020 with school opening. Early in the pandemic, both pediatric offices limited patient encounters to well-child visits in the first 2 years of life to not miss opportunities for childhood vaccinations. However, some parents were reluctant to bring their children to those visits. There was no significant change in frequency of healthy child visits during the pandemic.

To our knowledge, this was the first study from primary care pediatric practices in the United States to analyze the effect on infectious diseases during the first 9 months of the pandemic, including the 6-month time period after the reopening from the first 3 months of lockdown. One prior study from a primary care network in Massachusetts reported significant decreases in respiratory infectious diseases for children aged 0-17 years during the first months of the pandemic during lockdown.² A study in Tennessee that included hospital emergency department, urgent care, primary care, and retail health clinics also reported respiratory infection diagnoses as well as antibiotic prescription were reduced in the early months of the pandemic.³

Our study shows an overall reduction in frequency of respiratory illness visits in children 6-36 months old during the first 9 months of the COVID-19 pandemic. We learned the value of using technology in the form of virtual visits to render care. Perhaps as the pandemic subsides, many of the hand-washing and sanitizing practices will remain in place and lead to less frequent illness in children in the future. However, there may be temporary negative consequences from the “immune debt” that has occurred from a prolonged time span when children were not becoming infected with respiratory pathogens.⁴ We will see what unfolds in the future.

High-efficiency particulate air (HEPA) filters and ultraviolet (UV) light sterilization effectively remove SARS-CoV-2 particles from the air — the first such evidence in a real-world test, researchers report in the preprint server medRxiv.

The journal Nature reported Oct. 6 that the research, which has not been peer-reviewed, suggests the filters may help reduce the risk of hospital-acquired SARS-CoV-2.

Researchers, led by intensivist Andrew Conway-Morris, MBChB, PhD, with the division of anaesthesia in the school of clinical medicine at University of Cambridge, United Kingdom, write that earlier experiments assessed air filters’ ability to remove inactive particles in carefully controlled environments, but it was unknown how they would work in a real-world setting.

Co-author Vilas Navapurkar, MBChB, an ICU physician at Addenbrooke’s Hospital in Cambridge, United Kingdom, said that hospitals have used portable air filters when their isolation facilities are full, but evidence was needed as to whether such filters are effective or whether they provide a false sense of security.

The researchers installed the filters in two fully occupied COVID-19 wards — a general ward and an ICU. They chose HEPA filters because they can catch extremely small particles.

The team collected air samples from the wards during a week when the air filters were on and 2 weeks when they were turned off, then compared results.

According to the study, “airborne SARS-CoV-2 was detected in the ward on all five days before activation of air/UV filtration, but on none of the five days when the air/UV filter was operational; SARS-CoV-2 was again detected on four out of five days when the filter was off.”

Airborne SARS-CoV-2 was not frequently detected in the ICU, even when the filters were off.

Cheap and easy

According to the Nature article, the authors suggest several potential explanations for this, “including slower viral replication at later stages of the disease.” Therefore, the authors say, filtering the virus from the air might be more important in general wards than in ICUs.

The filters significantly reduced the other microbial bioaerosols in both the ward (48 pathogens detected before filtration, 2 after, P = .05) and the ICU (45 pathogens detected before filtration, 5 after P = .05).

National Institute for Occupational Safety and Health (NIOSH) cyclonic aerosol samplers and PCR tests were used to detect airborne SARS-CoV-2 and other microbial bioaerosol.

David Fisman, MD, an epidemiologist at the University of Toronto, who was not involved in the research, said in the Nature article, “This study suggests that HEPA air cleaners, which remain little-used in Canadian hospitals, are a cheap and easy way to reduce risk from airborne pathogens.”This work was supported by a Wellcome senior research fellowship to co-author Stephen Baker.

The journal Nature reported Oct. 6 that the research, which has not been peer-reviewed, suggests the filters may help reduce the risk of hospital-acquired SARS-CoV-2.

Researchers, led by intensivist Andrew Conway-Morris, MBChB, PhD, with the division of anaesthesia in the school of clinical medicine at University of Cambridge, United Kingdom, write that earlier experiments assessed air filters’ ability to remove inactive particles in carefully controlled environments, but it was unknown how they would work in a real-world setting.

Co-author Vilas Navapurkar, MBChB, an ICU physician at Addenbrooke’s Hospital in Cambridge, United Kingdom, said that hospitals have used portable air filters when their isolation facilities are full, but evidence was needed as to whether such filters are effective or whether they provide a false sense of security.

The researchers installed the filters in two fully occupied COVID-19 wards — a general ward and an ICU. They chose HEPA filters because they can catch extremely small particles.

The team collected air samples from the wards during a week when the air filters were on and 2 weeks when they were turned off, then compared results.

According to the study, “airborne SARS-CoV-2 was detected in the ward on all five days before activation of air/UV filtration, but on none of the five days when the air/UV filter was operational; SARS-CoV-2 was again detected on four out of five days when the filter was off.”

Airborne SARS-CoV-2 was not frequently detected in the ICU, even when the filters were off.

Cheap and easy

According to the Nature article, the authors suggest several potential explanations for this, “including slower viral replication at later stages of the disease.” Therefore, the authors say, filtering the virus from the air might be more important in general wards than in ICUs.

The filters significantly reduced the other microbial bioaerosols in both the ward (48 pathogens detected before filtration, 2 after, P = .05) and the ICU (45 pathogens detected before filtration, 5 after P = .05).

National Institute for Occupational Safety and Health (NIOSH) cyclonic aerosol samplers and PCR tests were used to detect airborne SARS-CoV-2 and other microbial bioaerosol.

David Fisman, MD, an epidemiologist at the University of Toronto, who was not involved in the research, said in the Nature article, “This study suggests that HEPA air cleaners, which remain little-used in Canadian hospitals, are a cheap and easy way to reduce risk from airborne pathogens.”This work was supported by a Wellcome senior research fellowship to co-author Stephen Baker.

The common-cold viruses rhinovirus (RV) and enterovirus (EV) continued to circulate among children during the COVID-19 pandemic while there were sharp declines in influenza, respiratory syncytial virus (RSV), and other respiratory viruses, new data indicate.

Researchers used data from the Centers for Disease Control and Prevention’s New Vaccine Surveillance Network. The cases involved 37,676 children in seven geographically diverse U.S. medical centers between December 2016 and January 2021. Patients presented to emergency departments or were hospitalized with RV, EV, and other acute respiratory viruses.

The investigators found that the percentage of children in whom RV/EV was detected from March 2020 to January 2021 was similar to the percentage during the same months in 2017-2018 and 2019-2020. However, the proportion of children infected with influenza, RSV, and other respiratory viruses combined dropped significantly in comparison to the three prior seasons.

Dermatology is an often-underutilized resource in the hospital setting. As the health care landscape has evolved, so has the role of the inpatient dermatologist.^1-3 Structural changes in the health system and advances in therapies have shifted dermatology from an admitting service to an almost exclusively outpatient practice. Improved treatment modalities led to decreases in the number of patients requiring admission for chronic dermatoses, and outpatient clinics began offering therapies once limited to hospitals.^1,4 Inpatient dermatology consultations emerged and continue to have profound effects on hospitalized patients regardless of their reason for admission.^1-11

Inpatient dermatologists supply knowledge in areas primary medical teams lack, and there is evidence that dermatology consultations improve the quality of care while decreasing cost.^2,5-7 Establishing correct diagnoses, preventing exposure to unnecessary medications, and reducing hospitalization duration and readmission rates are a few ways dermatology consultations positively impact hospitalized patients.^2,5-7,9,10 This study highlights the role of the dermatologist in the care of hospitalized patients at a large academic medical center in an urban setting and reveals how consultation supports the efficiency and efficacy of other services.

Materials and Methods

Study Design—This single-institution, cross-sectional retrospective study included all hospitalized patients at the Thomas Jefferson University Hospital (Philadelphia, Pennsylvania), who received an inpatient dermatology consultation completed by physicians of Jefferson Dermatology Associates between January 1, 2019, and December 31, 2019. The institutional review board at Thomas Jefferson University approved this study.

Data Collection—A list of all inpatient dermatology consultations in 2019 was provided by Jefferson Dermatology Associates. Through a retrospective chart review, data regarding the consultations were collected from the electronic medical record (Epic Systems) and recorded into the Research Electronic Data Capture system. Data on patient demographics, the primary medical team, the dermatology evaluation, and the hospital course of the patient were collected.

Results

Patient Characteristics—Dermatology received 253 inpatient consultation requests during this time period; 53% of patients were female and 47% were male, with a mean age of 55 years. Most patients were White (57%), while 34% were Black. Five percent and 4% of patients were Asian and Hispanic or Latino, respectively (Table 1). The mean duration of hospitalization for all patients was 15 days, and the average number of days to discharge following the first encounter with dermatology was 10 days.

Requesting Team and Reason for Consultation—Internal medicine consulted dermatology most frequently (34% of all consultations), followed by emergency medicine (14%) and a variety of other services (Table 1). Most dermatology consultations were placed to assist in achieving a diagnosis of a cutaneous condition (77%), while a minority were to assist in the management of a previously diagnosed disease (22%). A small fraction of consultations (5%) were to complete full-body skin examinations (FBSEs) to rule out infection or malignancy in candidates for organ transplantation, left ventricular assist devices, or certain chemotherapies. One FBSE was conducted to search for a primary tumor in a patient diagnosed with metastatic melanoma.

Most Common Final Diagnoses and Consultation Impact—Table 2 lists the most common final diagnosis categories, as well as the effects of the consultation on diagnosis, management, biopsies, hospitalization, and clinical improvement as documented by the primary medical provider. The most common final diagnoses were inflammatory and autoimmune (39%), such as contact dermatitis and seborrheic dermatitis; infectious (23%), such as varicella (primary or zoster) and bacterial furunculosis; drug reactions (20%), such as morbilliform drug eruptions; vascular (8%), such as vasculitis and calciphylaxis; neoplastic (7%), such as keratinocyte carcinomas and leukemia cutis; and other (15%), such as xerosis, keratosis pilaris, and miliaria rubra.

Impact on Diagnosis—Fifty-six percent of all consultations resulted in a change in diagnosis. When dermatology was consulted specifically to assist in the diagnosis of a patient (195 consultations), the working diagnosis of the primary team was changed 69% of the time. Thirty-five of these consultation requests had no preliminary diagnosis, and the primary team listed the working diagnosis as either rash or a morphologic description of the lesion(s). Sixty-three percent of suspected drug eruptions ended with a diagnosis of a form of drug eruption, while 20% of consultations for suspected cellulitis or bacterial infections were confirmed to be cellulitis or soft tissue infections.

Impact on Management—Regardless of the reason for the consultation, most consultations (86%) resulted in a change in management. The remaining 14% consisted of FBSEs with benign findings; cases of cutaneous metastases and leukemia cutis managed by oncology; as well as select cases of purpura fulminans, postfebrile desquamation, and postinflammatory hyperpigmentation.

Changes in management included alterations in medications, requests for additional laboratory work or imaging, additional consultation requests, biopsies, or specific wound care instructions. Seventy-five percent of all consultations were given specific medication recommendations by dermatology. Most (61%) were recommended to be given a topical steroid, antibiotic, or both. However, 45% of all consultations were recommended to initiate a systemic medication, most commonly antihistamines, antibiotics, steroids, antivirals, or immunomodulators. Dermatology recommended discontinuing specific medications in 16% of all consultations, with antibiotics being the most frequent culprit (17 antibiotics discontinued), owing to drug eruptions or misdiagnosed infections. Vancomycin, piperacillin-tazobactam, and trimethoprim-sulfamethoxazole were the most frequently discontinued antibiotics.

Dermatology was consulted for assistance in management of previously diagnosed cutaneous conditions 56 times (22% of all consultations), often regarding complicated cases of hidradenitis suppurativa (9 cases), pyoderma gangrenosum (5 cases), bullous pemphigoid (4 cases), or erythroderma (4 cases). Most of these cases required a single dermatology encounter to provide recommendations (71%), and 21% required 1 additional follow-up. Sixty-three percent of patients consulted for management assistance were noted to have improvement in their cutaneous condition by time of discharge, as documented by the primary provider in the medical record.

Twenty-eight percent of all consultations required at least 1 biopsy. Seventy-two percent of all biopsies were consistent with the dermatologist’s working diagnosis or highest-ranked differential diagnosis, and 16% of biopsy results were consistent with the second- or third-ranked diagnosis. The primary teams requested a biopsy 38 times to assist in diagnosis, as documented in the progress note or consultation request. Only 21 of these consultations (55% of requests) received at least 1 biopsy, as the remaining consultations did not require a biopsy to establish a diagnosis. The most common final diagnoses of consultations receiving biopsies included drug eruptions (5), leukemia cutis (4), vasculopathies (4), vasculitis (4), and calciphylaxis (3).

Impact on Hospitalization and Efficacy—Dermatology performed 217 consultations regarding patients already admitted to the hospital, and 92% remained hospitalized either due to comorbidities or complicated cutaneous conditions following the consultation. The remaining 8% were cleared for discharge. Dermatology received 36 consultation requests from emergency medicine physicians. Fifty-three percent of these patients were admitted, while the remaining 47% were discharged from the emergency department or its observation unit following evaluation.

Fifty-one percent of all consultations were noted to have improvement in their cutaneous condition by the time of discharge, as noted in the physical examination, progress note, or discharge summary of the primary team. Thirty percent of cases remained stable, where improvement was not noted in in the medical record. Most of these cases involved keratinocyte carcinomas scheduled for outpatient excision, benign melanocytic nevi found on FBSE, and benign etiologies that led to immediate discharge following consultation. Three percent of all consultations were noted to have worsened following consultation, including cases of calciphylaxis, vasculopathies, and purpura fulminans, as well as patients who elected for palliative care and hospice. The cutaneous condition by the time of discharge could not be determined from the medical record in 16% of all consultations.

Eighty-five percent of all consultations required a single encounter with dermatology. An additional 10% required a single follow-up with dermatology, while only 5% of patients required 3 or more encounters. Notably, these cases included patients with 1 or more severe cutaneous diseases, such as Sweet syndrome, calciphylaxis, Stevens-Johnson syndrome/toxic epidermal necrolysis, and hidradenitis suppurativa.

Comment

Although dermatology often is viewed as an outpatient specialty, this study provides a glimpse into the ways inpatient dermatology consultations optimize the care of hospitalized patients. Most consultations involved assistance in diagnosing an unknown condition, but several regarded pre-existing skin disorders requiring management aid. As a variety of medical specialties requested consultations, dermatology was able to provide care to a diverse group of patients with conditions varying in complexity and severity. Several specialties benefited from niche dermatologic expertise: hematology and oncology frequently requested dermatology to assist in diagnosis and management of the toxic effects of chemotherapy, cutaneous metastasis, or suspected cutaneous infections in immunocompromised patients. Cardiology patients were frequently evaluated for potential malignancy or infection prior to heart transplantation and initiation of antirejection immunosuppressants. Dermatology was consulted to differentiate cutaneous manifestations of critical illness from underlying systemic disease in the intensive care unit, and patients presenting to the emergency department often were examined to determine if hospital admission was necessary, with 47% of these consultations resulting in a discharge following evaluation by a dermatologist.

Our results were consistent with prior studies^1,5,6 that have reported frequent changes in final diagnosis following dermatology consultation, with 69% of working diagnoses changed in this study when consultation was requested for diagnostic assistance. When dermatology was consulted for diagnostic assistance, several of these cases lacked a preliminary differential diagnosis. Although the absence of a documented differential diagnosis may not necessarily reflect a lack of suspicion for a particular etiology, 86% of all consultations included a ranked differential or working diagnosis either in the consultation request or progress note prior to consultation. The final diagnoses of consultations without a preliminary diagnosis varied from the mild and localized to systemic and severe, further suggesting these cases reflected knowledge gaps of the primary medical team.

Integration of dermatology into the care of hospitalized patients could provide an opportunity for education of primary medical teams. With frequent consultation, primary medical teams may become more comfortable diagnosing and managing common cutaneous conditions specific to their specialty or extended hospitalizations.

Several consultations were requested to aid in management of cases of hidradenitis suppurativa, pyoderma gangrenosum, or bullous pemphigoid that either failed outpatient therapy or were complicated by superinfections. Despite the ranges in complexity, the majority of all consultations required a single encounter and led to improvement by the time of discharge, demonstrating the efficacy and efficiency of inpatient dermatologists.

Dermatology consultations often led to changes in management involving medications and additional workup. Changes in management also extended to specific wound care instructions provided by dermatology, as expected for cases of Stevens-Johnson syndrome/toxic epidermal necrolysis, Sweet syndrome, hidradenitis suppurativa, and pyoderma gangrenosum. However, patients with the sequelae of extended hospitalizations, such as chronic wounds, pressure ulcers, and edema bullae, also benefited from this expertise.

When patients required a biopsy, the final diagnoses were consistent with the dermatologist’s number one differential diagnosis or top 3 differential diagnoses 72% and 88% of the time, respectively. Only 55% of cases where the primary team requested a biopsy ultimately required a biopsy, as many involved clinical diagnoses such as urticaria. Not only was dermatology accurate in their preliminary diagnoses, but they decreased cost and morbidity by avoiding unnecessary procedures.

This study provided additional evidence to support the integration of dermatology into the hospital setting for the benefit of patients, primary medical teams, and hospital systems. Dermatology offers high-value care through the efficient diagnosis and management of hospitalized patients, which contributes to decreased cost and improved outcomes.^2,5-7,9,10 This study highlighted lesser-known areas of impact, such as the various specialty-specific services dermatology provides as well as the high rates of reported improvement following consultation. Future studies should continue to explore the field’s unique impact on hospitalized medicine as well as other avenues of care delivery, such as telemedicine, that may encourage dermatologists to participate in consultations and increase the volume of patients who may benefit from their care.

Data Collection—A list of all inpatient dermatology consultations in 2019 was provided by Jefferson Dermatology Associates. Through a retrospective chart review, data regarding the consultations were collected from the electronic medical record (Epic Systems) and recorded into the Research Electronic Data Capture system. Data on patient demographics, the primary medical team, the dermatology evaluation, and the hospital course of the patient were collected.

Results

Patient Characteristics—Dermatology received 253 inpatient consultation requests during this time period; 53% of patients were female and 47% were male, with a mean age of 55 years. Most patients were White (57%), while 34% were Black. Five percent and 4% of patients were Asian and Hispanic or Latino, respectively (Table 1). The mean duration of hospitalization for all patients was 15 days, and the average number of days to discharge following the first encounter with dermatology was 10 days.

Requesting Team and Reason for Consultation—Internal medicine consulted dermatology most frequently (34% of all consultations), followed by emergency medicine (14%) and a variety of other services (Table 1). Most dermatology consultations were placed to assist in achieving a diagnosis of a cutaneous condition (77%), while a minority were to assist in the management of a previously diagnosed disease (22%). A small fraction of consultations (5%) were to complete full-body skin examinations (FBSEs) to rule out infection or malignancy in candidates for organ transplantation, left ventricular assist devices, or certain chemotherapies. One FBSE was conducted to search for a primary tumor in a patient diagnosed with metastatic melanoma.

Most Common Final Diagnoses and Consultation Impact—Table 2 lists the most common final diagnosis categories, as well as the effects of the consultation on diagnosis, management, biopsies, hospitalization, and clinical improvement as documented by the primary medical provider. The most common final diagnoses were inflammatory and autoimmune (39%), such as contact dermatitis and seborrheic dermatitis; infectious (23%), such as varicella (primary or zoster) and bacterial furunculosis; drug reactions (20%), such as morbilliform drug eruptions; vascular (8%), such as vasculitis and calciphylaxis; neoplastic (7%), such as keratinocyte carcinomas and leukemia cutis; and other (15%), such as xerosis, keratosis pilaris, and miliaria rubra.

Impact on Diagnosis—Fifty-six percent of all consultations resulted in a change in diagnosis. When dermatology was consulted specifically to assist in the diagnosis of a patient (195 consultations), the working diagnosis of the primary team was changed 69% of the time. Thirty-five of these consultation requests had no preliminary diagnosis, and the primary team listed the working diagnosis as either rash or a morphologic description of the lesion(s). Sixty-three percent of suspected drug eruptions ended with a diagnosis of a form of drug eruption, while 20% of consultations for suspected cellulitis or bacterial infections were confirmed to be cellulitis or soft tissue infections.

Impact on Management—Regardless of the reason for the consultation, most consultations (86%) resulted in a change in management. The remaining 14% consisted of FBSEs with benign findings; cases of cutaneous metastases and leukemia cutis managed by oncology; as well as select cases of purpura fulminans, postfebrile desquamation, and postinflammatory hyperpigmentation.

Changes in management included alterations in medications, requests for additional laboratory work or imaging, additional consultation requests, biopsies, or specific wound care instructions. Seventy-five percent of all consultations were given specific medication recommendations by dermatology. Most (61%) were recommended to be given a topical steroid, antibiotic, or both. However, 45% of all consultations were recommended to initiate a systemic medication, most commonly antihistamines, antibiotics, steroids, antivirals, or immunomodulators. Dermatology recommended discontinuing specific medications in 16% of all consultations, with antibiotics being the most frequent culprit (17 antibiotics discontinued), owing to drug eruptions or misdiagnosed infections. Vancomycin, piperacillin-tazobactam, and trimethoprim-sulfamethoxazole were the most frequently discontinued antibiotics.

Dermatology was consulted for assistance in management of previously diagnosed cutaneous conditions 56 times (22% of all consultations), often regarding complicated cases of hidradenitis suppurativa (9 cases), pyoderma gangrenosum (5 cases), bullous pemphigoid (4 cases), or erythroderma (4 cases). Most of these cases required a single dermatology encounter to provide recommendations (71%), and 21% required 1 additional follow-up. Sixty-three percent of patients consulted for management assistance were noted to have improvement in their cutaneous condition by time of discharge, as documented by the primary provider in the medical record.

Twenty-eight percent of all consultations required at least 1 biopsy. Seventy-two percent of all biopsies were consistent with the dermatologist’s working diagnosis or highest-ranked differential diagnosis, and 16% of biopsy results were consistent with the second- or third-ranked diagnosis. The primary teams requested a biopsy 38 times to assist in diagnosis, as documented in the progress note or consultation request. Only 21 of these consultations (55% of requests) received at least 1 biopsy, as the remaining consultations did not require a biopsy to establish a diagnosis. The most common final diagnoses of consultations receiving biopsies included drug eruptions (5), leukemia cutis (4), vasculopathies (4), vasculitis (4), and calciphylaxis (3).

Impact on Hospitalization and Efficacy—Dermatology performed 217 consultations regarding patients already admitted to the hospital, and 92% remained hospitalized either due to comorbidities or complicated cutaneous conditions following the consultation. The remaining 8% were cleared for discharge. Dermatology received 36 consultation requests from emergency medicine physicians. Fifty-three percent of these patients were admitted, while the remaining 47% were discharged from the emergency department or its observation unit following evaluation.

Fifty-one percent of all consultations were noted to have improvement in their cutaneous condition by the time of discharge, as noted in the physical examination, progress note, or discharge summary of the primary team. Thirty percent of cases remained stable, where improvement was not noted in in the medical record. Most of these cases involved keratinocyte carcinomas scheduled for outpatient excision, benign melanocytic nevi found on FBSE, and benign etiologies that led to immediate discharge following consultation. Three percent of all consultations were noted to have worsened following consultation, including cases of calciphylaxis, vasculopathies, and purpura fulminans, as well as patients who elected for palliative care and hospice. The cutaneous condition by the time of discharge could not be determined from the medical record in 16% of all consultations.

Eighty-five percent of all consultations required a single encounter with dermatology. An additional 10% required a single follow-up with dermatology, while only 5% of patients required 3 or more encounters. Notably, these cases included patients with 1 or more severe cutaneous diseases, such as Sweet syndrome, calciphylaxis, Stevens-Johnson syndrome/toxic epidermal necrolysis, and hidradenitis suppurativa.

Comment

Although dermatology often is viewed as an outpatient specialty, this study provides a glimpse into the ways inpatient dermatology consultations optimize the care of hospitalized patients. Most consultations involved assistance in diagnosing an unknown condition, but several regarded pre-existing skin disorders requiring management aid. As a variety of medical specialties requested consultations, dermatology was able to provide care to a diverse group of patients with conditions varying in complexity and severity. Several specialties benefited from niche dermatologic expertise: hematology and oncology frequently requested dermatology to assist in diagnosis and management of the toxic effects of chemotherapy, cutaneous metastasis, or suspected cutaneous infections in immunocompromised patients. Cardiology patients were frequently evaluated for potential malignancy or infection prior to heart transplantation and initiation of antirejection immunosuppressants. Dermatology was consulted to differentiate cutaneous manifestations of critical illness from underlying systemic disease in the intensive care unit, and patients presenting to the emergency department often were examined to determine if hospital admission was necessary, with 47% of these consultations resulting in a discharge following evaluation by a dermatologist.

Our results were consistent with prior studies^1,5,6 that have reported frequent changes in final diagnosis following dermatology consultation, with 69% of working diagnoses changed in this study when consultation was requested for diagnostic assistance. When dermatology was consulted for diagnostic assistance, several of these cases lacked a preliminary differential diagnosis. Although the absence of a documented differential diagnosis may not necessarily reflect a lack of suspicion for a particular etiology, 86% of all consultations included a ranked differential or working diagnosis either in the consultation request or progress note prior to consultation. The final diagnoses of consultations without a preliminary diagnosis varied from the mild and localized to systemic and severe, further suggesting these cases reflected knowledge gaps of the primary medical team.

Integration of dermatology into the care of hospitalized patients could provide an opportunity for education of primary medical teams. With frequent consultation, primary medical teams may become more comfortable diagnosing and managing common cutaneous conditions specific to their specialty or extended hospitalizations.

Several consultations were requested to aid in management of cases of hidradenitis suppurativa, pyoderma gangrenosum, or bullous pemphigoid that either failed outpatient therapy or were complicated by superinfections. Despite the ranges in complexity, the majority of all consultations required a single encounter and led to improvement by the time of discharge, demonstrating the efficacy and efficiency of inpatient dermatologists.

Dermatology consultations often led to changes in management involving medications and additional workup. Changes in management also extended to specific wound care instructions provided by dermatology, as expected for cases of Stevens-Johnson syndrome/toxic epidermal necrolysis, Sweet syndrome, hidradenitis suppurativa, and pyoderma gangrenosum. However, patients with the sequelae of extended hospitalizations, such as chronic wounds, pressure ulcers, and edema bullae, also benefited from this expertise.

When patients required a biopsy, the final diagnoses were consistent with the dermatologist’s number one differential diagnosis or top 3 differential diagnoses 72% and 88% of the time, respectively. Only 55% of cases where the primary team requested a biopsy ultimately required a biopsy, as many involved clinical diagnoses such as urticaria. Not only was dermatology accurate in their preliminary diagnoses, but they decreased cost and morbidity by avoiding unnecessary procedures.

This study provided additional evidence to support the integration of dermatology into the hospital setting for the benefit of patients, primary medical teams, and hospital systems. Dermatology offers high-value care through the efficient diagnosis and management of hospitalized patients, which contributes to decreased cost and improved outcomes.^2,5-7,9,10 This study highlighted lesser-known areas of impact, such as the various specialty-specific services dermatology provides as well as the high rates of reported improvement following consultation. Future studies should continue to explore the field’s unique impact on hospitalized medicine as well as other avenues of care delivery, such as telemedicine, that may encourage dermatologists to participate in consultations and increase the volume of patients who may benefit from their care.

The continuing decline in COVID-19 incidence suggests the latest surge has peaked as new cases in children dropped for the 4th consecutive week, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.

Preliminary data from the Centers for Disease Control and Prevention, however, show an uptick in new cases in late September, largely among younger children, that may indicate otherwise. Those data have a potential 2-week reporting delay, the CDC said on its COVID Data Tracker, so the most recent points on the graph (see above) could still go up.

The AAP and the CHA said that 173,000 new cases were reported for the week of Sept. 24-30, down 16% from the week before and 31% from the peak in early September. Those new cases made up almost 27% of all cases for the week, and the nearly 5.9 million child cases that have been reported since the start of the pandemic represent 16.2% of cases among Americans of all ages, the two groups said in their weekly COVID-19 report.

The CDC data on new cases by age group suggest that younger children have borne a heavier burden in the summer surge of COVID than they did last winter. The rate of new cases was not as high for 16- and 17-year-olds in the summer, but the other age groups all reached higher peaks than in the winter, including the 12- to 15-year-olds, who have been getting vaccinated since May, according to the COVID Data Tracker.

With vaccination approval getting closer for children under age 12 years, initiation in those already eligible continues to slide. Those aged 12-15 made up just 6.9% of new vaccinations during the 2 weeks from Sept. 21 to Oct. 4, and that figure has been dropping since July 13-26, when it was 14.1%. Vaccine initiation among 16- and 17-year-olds over that time has dropped by almost half, from 5.4% to 2.9%, the CDC data show.

All the vaccinations so far add up to this: Almost 55% of those aged 12-15 have gotten at least one dose of COVID vaccine, as have over 62% of those aged 16-17, and 52% of the older group is fully vaccinated, as is 44% of the younger group. Altogether, 10.8 million children were fully vaccinated as of Oct. 4, including those under 12 who may be participating in clinical trials or had a birth date entered incorrectly, the CDC said.

Irish dermatologists are reporting two more cases of a rare skin ulcer known as reactive infectious mucocutaneous eruption (RIME) in teenage males who were infected with COVID-19. A similar case in an adolescent, also with ulcers affecting the mouth and penis, was reported earlier in 2021 in the United States.

“Our cases show that a swab for COVID-19 can be added to the list of investigations for mucosal and cutaneous rashes in children and probably adults,” said dermatologist Stephanie Bowe, MD, of South Infirmary-Victoria University Hospital in Cork, Ireland, in an interview. “Our patients seemed to improve with IV steroids, but there is not enough data to recommend them to all patients or for use in the different cutaneous presentations associated with COVID-19.”

The new case reports were presented at the 2021 meeting of the World Congress of Pediatric Dermatology and published in Pediatric Dermatology.

Researchers have noted that skin disorders linked to COVID-19 infection are different than those in adults. In children, the conditions include morbilliform rash, pernio-like acral lesions, urticaria, macular erythema, vesicular eruption, papulosquamous eruption, and retiform purpura. “The pathogenesis of each is not fully understood but likely related to the inflammatory response to COVID-19 and the various pathways within the body, which become activated,” Dr. Bowe said.

The first patient, a 17-year-old boy, presented at clinic 6 days after he’d been confirmed to be infected with COVID-19 and 8 days after developing fever and cough. “He had a 2-day history of conjunctivitis and ulceration of his oral mucosa, erythematous circumferential erosions of the glans penis with no other cutaneous findings,” the authors write in the report.

The boy “was distressed and embarrassed about his genital ulceration and also found eating very painful due to his oral ulceration,” Dr. Bowe said.

The second patient, a 14-year-old boy, was hospitalized 7 days after a positive COVID-19 test and 9 days after developing cough and fever. “He had a 5-day history of ulceration of the oral mucosa with mild conjunctivitis,” the authors wrote. “Ulceration of the glans penis developed on day 2 of admission.”

The 14-year-old was sicker than the 17-year-old boy, Dr. Bowe said. “He was unable to tolerate an oral diet for several days and had exquisite pain and vomiting with his coughing fits.”

This patient had a history of recurrent herpes labialis, but it’s unclear whether herpes simplex virus (HSV) played a role in the COVID-19–related case. “There is a possibility that the patient was more susceptible to viral cutaneous reactions during COVID-19 infection, but we didn’t have any definite history of HSV infection at the time of mucositis,” Dr. Bowe said. “We also didn’t have any swabs positive for HSV even though several were done at the time.”

Both patients received IV steroids – hydrocortisone at 100 mg 3 times daily for 3 days. This treatment was used “because of deterioration in symptoms and COVID-19 infection,” Dr. Bowe said. “IV steroids were used for respiratory symptoms of COVID-19, so we felt these cutaneous symptoms may have also been caused by an inflammatory response and might benefit from steroids. There was very little literature about this specific situation, though.”

She added that intravenous steroids wouldn’t be appropriate for most pediatric patients, and noted that “their use is controversial in the literature for erythema multiforme and RIME.”

In addition, the patients received betamethasone valerate 0.1% ointment once daily, hydrocortisone 2.5 mg buccal tablets 4 times daily, analgesia with acetaminophen and ibuprofen, and intravenous hydration. The first patient also received prednisolone 1% eye drops, while the second patient was given lidocaine hydrochloride mouthwash and total parenteral nutrition for 5 days.

The patients were discharged after 4 and 14 days, respectively.

Dermatologists in Massachusetts reported a similar case earlier in 2021 in a 17-year-old boy who was positive for COVID-19 and presented with “shallow erosions of the vermilion lips and hard palate, circumferential erythematous erosions of the periurethral glans penis, and five small vesicles on the trunk and upper extremities.”

The patient received betamethasone valerate 0.1% ointment for the lips and penis, intraoral dexamethasone solution, viscous lidocaine, acetaminophen, and ibuprofen. He also received oral prednisone at approximately 1 mg/kg daily for 4 consecutive days after worsening oral pain. A recurrence of oral pain 3 months later was resolved with a higher and longer treatment with oral prednisone.

Dermatologists have also reported cases of erythema multiforme lesions of the mucosa in adults with COVID-19. One case was reported in Iran, and the other in France.

The authors report no study funding and disclosed no relevant financial relationships.

A phase 3, randomized, double-blind, controlled trial has shown that oteseconazole (Mycovia Pharmaceuticals), an oral antifungal agent, is safe and effective in treating acute and recurrent yeast infections (vulvovaginal candidiasis [VVC]) and in preventing  recurrence of acute VVC episodes.

Findings of the ultraVIOLET trial, which compared oteseconazole with the standard fluconazole, were presented at IDWeek 2021, an annual scientific meeting on infectious diseases, by lead author Mark G. Martens, MD, a professor in the department of obstetrics and gynecology at Drexel University College of Medicine in Philadelphia.

About 75% of all women will have a yeast infection in their lifetime, Dr. Martens noted. About 138 million women worldwide have recurring episodes (at least three acute episodes in the last year) of the debilitating condition.

“Recurrent vulvovaginal candidiasis typically requires treatment of the acute episode followed by long-term suppressive therapy with either weekly or biweekly fluconazole,” Dr. Martens said. However, when therapy stops, more than 50% of patients with recurrent VVC experience an infection within the next 6 months, which takes a significant toll on daily life.

Additionally, fluconazole has been linked with safety issues concerning chronic dosing, he said, citing liver toxicity, drug-drug interactions and “increased risk of miscarriage and birth defects when used during pregnancy.”

Topical treatments have been associated with messy application and burning, he noted.

For this study, researchers enrolled 219 women with a history of recurrent VVC at 51 U.S. sites. Participants were randomized either to 600 mg oteseconazole on day 1, 450 mg oteseconazole on day 2 or placebo capsules; or three sequential 150 mg doses (every 72 hours) of fluconazole together with matching placebo capsules.

In the maintenance phase, 185 women with resolved acute VVC (clinical signs and symptoms were scored below 3) on day 14 received 150 mg oteseconazole or placebo weekly for 11 weeks.

Oteseconazole was superior to fluconazole/placebo in the proportion of subjects with at least one culture-verified acute VVC episode through week 50 in the intent-to-treat population (P < .001) which included subjects who failed to clear their infection in the induction phase.

The average percentage of participants with at least one culture-verified acute VVC episode through week 50 was lower in the oteseconazole group (5.1%), compared with the fluconazole/placebo group (42.2%).

Oteseconazole was noninferior to fluconazole in the proportion of subjects with resolved acute VVC infections at day 14 – 93.2% for the oteseconazole group vs. 95.8% for the fluconazole/placebo group.

The percentages of women who had at least one treatment-emergent adverse event (TEAE) were similar – 54% in the oteseconazole group and 64% in the fluconazole/placebo group.  Most TEAEs were mild or moderate and there were no drug-related SAEs or adverse effects on liver function.

“There was no difference in the two groups in he baseline characteristics of age, race, and history of diabetes,” he said.

Oluwatosin Goje, MD, an ob.gyn. with the Cleveland Clinic told this news organization that the drug may offer another option for women who don’t respond to azoles.

“The CDC guidelines say, and I agree, that most episodes of recurrent VVC that are caused by Candida albicans will respond to topical azoles, to oral azoles, to the known drugs that are available. You just may have to use them for a prolonged period of time,” Dr. Goje said. But some patients won’t respond to azoles, the currently available drugs, and topical treatments – so new options are welcome for them, she noted.

She pointed out that the U.S. Food and Drug Administration in June approved ibrexafungerp (Brexafemme), the first oral nonazole treatment for vaginal yeast infections. It was the first approved medicine in a novel antifungal class in more than 2 decades.

Dr. Goje, who runs a large clinic with substantial numbers of women with recurrent yeast infections, said the psychosocial problems women with recurrent yeast infections face – and the time off work and money spent trying to get temporary relief from over-the-counter medications – is underestimated.

“Women have long suffered vaginitis. It can be a lot of social and economic burden. So anything in the toolbox to help women is welcome,” Dr. Goje said.

A phase 3, randomized, double-blind, controlled trial has shown that oteseconazole (Mycovia Pharmaceuticals), an oral antifungal agent, is safe and effective in treating acute and recurrent yeast infections (vulvovaginal candidiasis [VVC]) and in preventing  recurrence of acute VVC episodes.

Findings of the ultraVIOLET trial, which compared oteseconazole with the standard fluconazole, were presented at IDWeek 2021, an annual scientific meeting on infectious diseases, by lead author Mark G. Martens, MD, a professor in the department of obstetrics and gynecology at Drexel University College of Medicine in Philadelphia.

About 75% of all women will have a yeast infection in their lifetime, Dr. Martens noted. About 138 million women worldwide have recurring episodes (at least three acute episodes in the last year) of the debilitating condition.

“Recurrent vulvovaginal candidiasis typically requires treatment of the acute episode followed by long-term suppressive therapy with either weekly or biweekly fluconazole,” Dr. Martens said. However, when therapy stops, more than 50% of patients with recurrent VVC experience an infection within the next 6 months, which takes a significant toll on daily life.

Additionally, fluconazole has been linked with safety issues concerning chronic dosing, he said, citing liver toxicity, drug-drug interactions and “increased risk of miscarriage and birth defects when used during pregnancy.”

Topical treatments have been associated with messy application and burning, he noted.
