Diagnosis: Rosacea with Demodex mites

Under light microscopy, the scraping revealed Demodex mites (FIGURE 2). It has been proposed that these mites play a role in the inflammatory process seen in rosacea, although studies have yet to determine whether the inflammatory symptoms of rosacea cause the mites to proliferate or if the mites contribute to the initial inflammatory process.^1,2

Demodex folliculorum and D brevis are part of normal skin flora; they are found in about 12% of all follicles and most commonly involve the face.³ They often become abundant in the presence of numerous sebaceous glands. Men have more sebaceous glands than women do, and thus run a greater risk for infestation with mites. An abnormal proliferation of Demodex mites can lead to demodicosis.

A proliferation of Demodex is seen in almost all cases of papulopustular rosacea and more than 60% of cases of erythematotelangiectatic rosacea.

Demodex mites can be examined microscopically via the skin surface sampling technique known as scraping, which was done in this case. Samples taken from the papules and pustules utilizing a #15 blade are placed in immersion oil on a glass slide, cover-slipped, and examined by light microscopy.

Rosacea is thought to be an inflammatory disease in which the immune system is triggered by a variety of factors, including UV light, heat, stress, alcohol, hormonal influences, and microorganisms.^1,4 The disease is found in up to 10% of the population worldwide.¹

The diagnosis of rosacea requires at least 1 of the 2 “core features”—persistent central facial erythema or phymatous changes—or 2 of 4 “major features”: papules/pustules, ocular manifestation, flushing, and telangiectasias. There are 3 phenotypes: ocular, papulopustular, and erythematotelangiectatic.^5,6

The connection. Papulopustular and erythematotelangiectatic rosacea may be caused by a proliferation of Demodex mites and increased vascular endothelial growth factor production.² In fact, a proliferation of Demodex is seen in almost all cases of papulopustular rosacea and more than 60% of cases of erythematotelangiectatic rosacea.²

Patient age and distribution of lesions narrowed the differential

Acne vulgaris is an inflammatory disease of the pilosebaceous units caused by increased sebum production, inflammation, and bacterial colonization (Propionibacterium acnes) of hair follicles on the face, neck, chest, and other areas. Both inflammatory and noninflammatory lesions can be present, and in serious cases, scarring can result.⁷ The case patient’s age and accompanying broad erythema were more consistent with rosacea than acne vulgaris.

Seborrheic dermatitis is a common skin condition usually stemming from an inflammatory reaction to a common yeast. Classic symptoms include scaling and erythema of the scalp and central face, as well as pruritus. Topical antifungals such as ketoconazole 2% cream and 2% shampoo are the mainstay of treatment.⁸ The broad distribution and papulopustules in this patient argue against the diagnosis of seborrheic dermatitis.

Systemic lupus erythematosus is a systemic inflammatory disease that often has cutaneous manifestations. Acute lupus manifests as an erythematous “butterfly rash” across the face and cheeks. Chronic discoid lupus involves depigmented plaques, erythematous macules, telangiectasias, and scarring with loss of normal hair follicles. These findings classically are photodistributed.⁹ The classic broad erythema extending from the cheeks over the bridge of the nose was not present in this patient.

Treatment is primarily topical

Mild cases of rosacea often can be managed with topical antibiotic creams. More severe cases may require systemic antibiotics such as tetracycline or doxycycline, although these are used with caution due to the potential for antibiotic resistance.

Ivermectin 1% cream is a US Food and Drug Administration–approved medication that is applied once daily for up to a year to treat the inflammatory pustules associated with Demodex mites. Although it is costly, studies have shown better results with topical ivermectin than with other topical medications (eg, metronidazole 0.75% gel or cream). However, metronidazole 0.75% gel applied twice daily and oral tetracycline 250 mg or doxycycline 100 mg daily or twice daily for at least 2 months often are utilized when the cost of topical ivermectin is prohibitive.¹⁰

Our patient was treated with a combination of doxycycline 100 mg daily for 30 days and ivermectin 1% cream daily. He was also instructed to apply sunscreen daily. He improved rapidly, and the daily topical ivermectin was discontinued after 6 months.

Ruptured abdominal aortic aneurysms (AAAs) caused about 6000 deaths annually in the United States between 2014 and 2020¹ and are associated with a pooled mortality rate of 81%.² They result from a distinct degenerative process of the layers of the aortic wall.² An AAA is defined as an abdominal aorta whose dilation is > 50% normal (more commonly, a diameter > 3 cm).^3,4 The risk for rupture correlates closely with size; most ruptures occur in aneurysms > 5.5 cm^3,4 (TABLE 1⁵).

Most AAAs are asymptomatic and often go undetected until rupture, resulting in poor outcomes. Because of a low and declining prevalence of AAA and ruptured AAA in developed countries, screening recommendations target high-risk groups rather than the general population.^4,6-8 This review summarizes risk factors, prevalence, and current evidence-based screening and management recommendations for AAA.

Who’s at risk?

Age is the most significant nonmodifiable risk factor, with AAA rupture uncommon in patients younger than 55 years.⁹ One retrospective study found the odds ratio (OR) for diagnosing AAA was 9.41 in adults ages 65 to 69 years (95% CI, 8.76-10.12; P < .0001) and 14.46 (95% CI, 13.45-15.55; P < .0001) in adults ages 70 to 74 years, compared to adults younger than 55 years.¹⁰

Smoking is the most potent modifiable risk factor for AAA. Among patients with AAA, > 90% have a history of smoking.⁴ The association between smoking and AAA is dose dependent, with an OR of 2.61 (95% CI, 2.47-2.74) in patients with a pack-per-year history < 5 years and 12.13 (95% CI, 11.66-12.61) in patients with a pack-per-year history > 35 years, compared to nonsmokers.¹⁰ The risk for AAA increases with smoking duration but decreases with cessation duration.^4,10 Smoking cessation remains an important intervention, as active smokers have higher AAA rupture rates.¹¹

Other risk factors for AAA include concomitant cardiovascular disease (CVD) such as coronary artery disease (CAD), cerebrovascular disease, atherosclerosis, dyslipidemia, and hypertension.¹⁰ Factors associated with reduced risk for AAA include African American race, Hispanic ethnicity, Asian ethnicity, diabetes, smoking cessation, consuming fruits and vegetables > 3 times per week, and exercising more than once per week.^6,10

Prevalence declines but sex-based disparities in outcomes persist

The prevalence of AAA has declined in the United States and Europe in recent decades, correlating with declining rates of smoking.^4,12 Reports published between 2011 and 2019 estimate that AAA prevalence in men older than 60 years has declined over time, with a prevalence of 1.2% to 3.3%.⁶ The prevalence of AAA has also decreased in women,^6,13,14 estimated in 1 study to be as low as 0.74%.¹³ Similarly, deaths from ruptured AAA have declined markedly in the United States—by 70% between 1999 and 2016 according to 1 analysis.⁹

One striking difference in the male-female data is that although AAAs are more common in men, there is a 2- to 4-fold higher risk for rupture in women, who account for nearly half of all AAA-related deaths.^9,10,15-17 The reasons for this heightened risk to women despite lower prevalence are not fully understood but are likely multifactorial and related to a general lack of screening for AAA in women, tendency for AAA to rupture at smaller diameters in women, rupture at an older age in women, and a history of worse surgical outcomes in women than men (though the gap in surgical outcomes appears to be closing).^9,10,18

Continue to: While declines in AAA and AAA-related...

While declines in AAA and AAA-related death are largely attributed to lower smoking rates, other likely contributing factors include the implementation of screening programs, incidental detection during cross-sectional imaging, and improved surgical techniques and management of CV risk factors (eg, hypertension, hyperlipidemia).^9,10

The benefits of screening older men

Randomized controlled trials (RCTs) have demonstrated the benefits of AAA screening programs. A meta-analysis of 4 population­based RCTs of AAA screening in men ≥ 65 years demonstrated statistically significant reductions in AAA rupture (OR = 0.62; 95% CI, 0.55-0.70) and death from AAA (OR = 0.65; 95% CI, 0.57-0.74) over 12 to 15 years, with a number needed to screen (NNS) of 305 (95% CI, 248-411) to prevent 1 AAA-related death.¹⁸ The study also found screening decreases the rate of emergent surgeries for AAA (OR = 0.57; 95% CI, 0.48-0.68) while increasing the number of elective surgeries (OR = 1.44; 95% CI, 1.34-1.55) over 4 to 15 years.¹⁸

Only 1 study has demonstrated an improvement in all-cause mortality with screening programs, with a relatively small benefit (OR = 0.97; 95% CI, 0.94-0.99).¹⁹ Only 1 of the studies included women and, while underpowered, showed no difference in AAA-related death or rupture.²⁰ Guidelines and recommendations of various countries and professional societies focus screening on subgroups at highest risk for AAA.^4,6-8,18

Screening recommendations from USPSTF and others

The US Preventive Services Task Force ­(USPSTF) currently recommends one-time ultrasound screening for AAA in men ages 65 to 75 years who have ever smoked (commonly defined as having smoked > 100 cigarettes) in their lifetime.⁶ This grade “B” recommendation, initially made in 2005 and reaffirmed in the 2014 and 2019 ­USPSTF updates, recommends screening the ­highest-risk segment of the population (ie, older male smokers).⁶

In men ages 65 to 75 years with no smoking history, rather than routine screening, the USPSTF recommends selectively offering screening based on the patient’s medical history, family history, risk factors, and personal values (with a “C” grade).⁶ The USPSTF continues to recommend against screening for AAA in women with no smoking history and no family history of AAA.⁶ According to the USPSTF, the evidence is insufficient to recommend for or against screening women ages 65 to 75 years who have ever smoked or have a family history of AAA (“I” statement).⁶

Continue to: One critique of the USPSTF recommendations

One critique of the USPSTF recommendations is that they fail to detect a significant portion of patients with AAA and AAA rupture. For example, in a retrospective analysis of 55,197 patients undergoing AAA repair, only 33% would have been detected by the USPSTF grade “B” recommendation to screen male smokers ages 65 to 75 years, and an analysis of AAA-related fatalities found 43% would be missed by USPSTF criteria.^9,21

Screening guidelines from the Society for Vascular Surgery (SVS) are broader than those of the USPSTF, in an attempt to capture a larger percentage of the population at risk for AAA-related disease by extrapolating from epidemiologic data. The SVS guidelines include screening for women ages 65 to 75 years with a smoking history, screening men and women ages 65 to 75 years who have a first-degree relative with AAA, and consideration of screening patients older than 75 years if they are in good health and have a first-degree relative with AAA or a smoking history and have not been previously screened.⁴ However, these expanded recommendations are not supported by patient-oriented evidence.⁶

Attempts to broaden screening guidelines must be tempered by potential risks for harm, primarily overdiagnosis (ie, diagnosing AAAs that would not otherwise rise to clinical significance) and overtreatment (ie, resulting in unnecessary imaging, appointments, anxiety, or surgery). Negative psychological effects on quality of life after a diagnosis of AAA have not been shown to cause significant harm.^6,18

A recent UK analysis found that screening programs for AAA in women modeled after those in men are not cost effective, with an NNS to prevent 1 death of 3900 in women vs 700 in men.^15,18 Another recent trial of ultrasound screening in 5200 high-risk women ages 65 to 74 years found an AAA incidence of 0.29% (95% CI, 0.18%-0.48%) in which only 3 large aneurysms were identified.²²

Smoking is the most potent modifiable risk factor for abdominal aortic aneurysm.

In the United States, rates of screening for AAA remain low.²³ One study has shown electronic medical record–based reminders increased screening rates from 48% to 80%.²⁴ Point-of-care bedside ultrasound performed by clinicians also could improve screening rates. Multiple studies have demonstrated that screening and diagnosis of AAA can be performed safely and effectively at the bedside by nonradiologists such as family physicians and emergency physicians.^25-28 In 1 study, such exams added < 4 minutes to the patient encounter.²⁶ Follow-up surveillance schedules for those identified as having a AAA are summarized in TABLE 2.⁴

Continue to: Management options

Management options: Immediate repair or surveillance?

After diagnosing AAA, important decisions must be made regarding management, including indications for surgical repair, appropriate follow-up surveillance, and medications for secondary prevention and cardiovascular risk reduction.

EVAR vs open repair

The 2 main surgical strategies for aneurysm repair are open repair and endovascular repair (EVAR). In the United States, EVAR is becoming the more common approach and was used to repair asymptomatic aneurysms in > 80% of patients and ruptured aneurysms in 50% of patients.⁶ There have been multiple RCTs assessing EVAR and open repair for large and small aneurysms.^29-34 Findings across these studies consistently show EVAR is associated with lower immediate (ie, ­30-day) morbidity and mortality but no ­longer-term survival benefit compared to open repair.

EVAR procedures require ongoing long-term surveillance for endovascular leakage and other complications, resulting in an increased need for re-intervention.^31,33,35 For these reasons, the National Institute for Health and Care Excellence (NICE) guidelines suggest open repair as the preferred modality.⁷ However, SVS and the American College of Cardiology Foundation/American Heart Association guidance support either EVAR or open repair, noting that open repair may be preferable in patients unable to engage in long-term follow-up surveillance.³⁶

Indications for repair. In general, repair is indicated when an aneurysm reaches or exceeds 5.5 cm.^4,7 Both SVS and NICE also recommend clinicians consider surgical repair of smaller, rapidly expanding aneurysms (> 1 cm over a 1-year period).^4,7 Based on evidence suggesting a higher risk for rupture in women with smaller aneurysms,^14,37 SVS recommends clinicians consider surgical repair in women with an AAA ≥ 5.0 cm. Several RCTs evaluating the benefits of immediate repair for smaller-sized aneurysms (4.0-5.5 cm) favored surveillance.^38,39 Accepted indications for surgical repair are summarized in TABLE 3.^4,7,34Surgical repair recommendations also are based on aneurysm morphology, which can be fusiform or saccular (FIGURE). More than 90% of AAAs are fusiform.⁴⁰ Although saccular AAAs are less common, some studies suggest they are more prone to rupture than fusiform AAAs, and SVS guidelines suggest surgical repair of saccular aneurysms regardless of size.^4,41,42

Perioperative and long-term risks. Both EVAR and open repair of AAA carry a high perioperative and long-term risk for death, as patients often have multiple comorbidities. A 2019 trial comparing EVAR to open repair with 14 years of follow-up reported death in 68% of patients in the EVAR group and 70% in the open repair group. ³¹ Among these deaths, 2.7% in the EVAR group and 3.7% in the open repair group were aneurysm related.³¹ The study also found a second surgical intervention was required in 19.8% of patients in the open repair group and 26.7% in the EVAR group.³¹

Continue to: When assessing perioperative risk...

Although abdominal aortic aneurysms are more common in men, there is a 2- to 4-fold higher risk for rupture in women.

When assessing perioperative risk, SVS guidelines recommend clinicians employ a shared decision-making approach with patients that incorporates Vascular Quality Initiative (VQI) mortality risk score.⁴ (VQI risk calculators are available at https://qxmd.com/vascular-study-group-new-england-decision-support-tools.⁴³)

Medication management

Based on the close association of aortic aneurysm with atherosclerotic CVD (ASCVD), professional societies such as the European Society of Cardiology and European Atherosclerosis Society (ESC/EAS) have suggested aortic aneurysm is equivalent to ASCVD and should be managed medically in a similar manner to peripheral arterial disease.⁴⁴ Indeed, many patients with AAA may have concomitant CAD or other arterial vascular diseases (eg, carotid, lower extremity).

Statins. In its guidelines, the ESC/EAS consider patients with AAA at “very high risk” for adverse CV events and suggest pharmacotherapy with high-intensity statins, adding ezetimibe or proprotein convertase ­subtilisin/kexin type 9 (PCSK9) inhibitors if needed, to reduce low-density lipoprotein cholesterol ≥ 50% from baseline, with a goal of < 55 mg/dL.⁴⁴ Statin therapy additionally lowers all-cause postoperative mortality in patients undergoing AAA repair but does not affect the rate of aneurysm expansion.⁴⁵

Aspirin and other anticoagulants. Although aspirin therapy may be indicated for the secondary prevention of other cardiovascular events that may coexist with AAA, it does not appear to affect the rate of growth or prevent rupture of aneurysms.^46,47 In addition to aspirin, anticoagulants such as clopidogrel, enoxaparin, and warfarin are not recommended when the presence of AAA is the only indication.⁴

The USPSTF continues to recommend against screening in women with no smoking history and no family history of abdominal aortic aneurysm.

Other medications. Angiotensin-­converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, and antibiotics (eg, doxycycline) have been studied as a treatment for AAA. However, none has shown benefit in reducing aneurysm growth or rupture and they are not recommended for that sole purpose.^4,48

Metformin. There is a negative association between diabetes and AAA expansion and rupture. Several cohort studies have indicated that this may be an independent effect driven primarily by exposure to metformin. While it is not unreasonable to consider this another important indication for metformin use in patients with diabetes, RCT evidence has yet to establish a role for metformin in patients without diabetes who have AAA.^48,49

Randomized controlled trials (RCTs) have demonstrated the benefits of AAA screening programs. A meta-analysis of 4 population­based RCTs of AAA screening in men ≥ 65 years demonstrated statistically significant reductions in AAA rupture (OR = 0.62; 95% CI, 0.55-0.70) and death from AAA (OR = 0.65; 95% CI, 0.57-0.74) over 12 to 15 years, with a number needed to screen (NNS) of 305 (95% CI, 248-411) to prevent 1 AAA-related death.¹⁸ The study also found screening decreases the rate of emergent surgeries for AAA (OR = 0.57; 95% CI, 0.48-0.68) while increasing the number of elective surgeries (OR = 1.44; 95% CI, 1.34-1.55) over 4 to 15 years.¹⁸

Only 1 study has demonstrated an improvement in all-cause mortality with screening programs, with a relatively small benefit (OR = 0.97; 95% CI, 0.94-0.99).¹⁹ Only 1 of the studies included women and, while underpowered, showed no difference in AAA-related death or rupture.²⁰ Guidelines and recommendations of various countries and professional societies focus screening on subgroups at highest risk for AAA.^4,6-8,18

Screening recommendations from USPSTF and others

The US Preventive Services Task Force ­(USPSTF) currently recommends one-time ultrasound screening for AAA in men ages 65 to 75 years who have ever smoked (commonly defined as having smoked > 100 cigarettes) in their lifetime.⁶ This grade “B” recommendation, initially made in 2005 and reaffirmed in the 2014 and 2019 ­USPSTF updates, recommends screening the ­highest-risk segment of the population (ie, older male smokers).⁶

In men ages 65 to 75 years with no smoking history, rather than routine screening, the USPSTF recommends selectively offering screening based on the patient’s medical history, family history, risk factors, and personal values (with a “C” grade).⁶ The USPSTF continues to recommend against screening for AAA in women with no smoking history and no family history of AAA.⁶ According to the USPSTF, the evidence is insufficient to recommend for or against screening women ages 65 to 75 years who have ever smoked or have a family history of AAA (“I” statement).⁶

Continue to: One critique of the USPSTF recommendations

One critique of the USPSTF recommendations is that they fail to detect a significant portion of patients with AAA and AAA rupture. For example, in a retrospective analysis of 55,197 patients undergoing AAA repair, only 33% would have been detected by the USPSTF grade “B” recommendation to screen male smokers ages 65 to 75 years, and an analysis of AAA-related fatalities found 43% would be missed by USPSTF criteria.^9,21

Screening guidelines from the Society for Vascular Surgery (SVS) are broader than those of the USPSTF, in an attempt to capture a larger percentage of the population at risk for AAA-related disease by extrapolating from epidemiologic data. The SVS guidelines include screening for women ages 65 to 75 years with a smoking history, screening men and women ages 65 to 75 years who have a first-degree relative with AAA, and consideration of screening patients older than 75 years if they are in good health and have a first-degree relative with AAA or a smoking history and have not been previously screened.⁴ However, these expanded recommendations are not supported by patient-oriented evidence.⁶

Attempts to broaden screening guidelines must be tempered by potential risks for harm, primarily overdiagnosis (ie, diagnosing AAAs that would not otherwise rise to clinical significance) and overtreatment (ie, resulting in unnecessary imaging, appointments, anxiety, or surgery). Negative psychological effects on quality of life after a diagnosis of AAA have not been shown to cause significant harm.^6,18

A recent UK analysis found that screening programs for AAA in women modeled after those in men are not cost effective, with an NNS to prevent 1 death of 3900 in women vs 700 in men.^15,18 Another recent trial of ultrasound screening in 5200 high-risk women ages 65 to 74 years found an AAA incidence of 0.29% (95% CI, 0.18%-0.48%) in which only 3 large aneurysms were identified.²²

Smoking is the most potent modifiable risk factor for abdominal aortic aneurysm.

In the United States, rates of screening for AAA remain low.²³ One study has shown electronic medical record–based reminders increased screening rates from 48% to 80%.²⁴ Point-of-care bedside ultrasound performed by clinicians also could improve screening rates. Multiple studies have demonstrated that screening and diagnosis of AAA can be performed safely and effectively at the bedside by nonradiologists such as family physicians and emergency physicians.^25-28 In 1 study, such exams added < 4 minutes to the patient encounter.²⁶ Follow-up surveillance schedules for those identified as having a AAA are summarized in TABLE 2.⁴

Continue to: Management options

Management options: Immediate repair or surveillance?

After diagnosing AAA, important decisions must be made regarding management, including indications for surgical repair, appropriate follow-up surveillance, and medications for secondary prevention and cardiovascular risk reduction.

EVAR vs open repair

The 2 main surgical strategies for aneurysm repair are open repair and endovascular repair (EVAR). In the United States, EVAR is becoming the more common approach and was used to repair asymptomatic aneurysms in > 80% of patients and ruptured aneurysms in 50% of patients.⁶ There have been multiple RCTs assessing EVAR and open repair for large and small aneurysms.^29-34 Findings across these studies consistently show EVAR is associated with lower immediate (ie, ­30-day) morbidity and mortality but no ­longer-term survival benefit compared to open repair.

EVAR procedures require ongoing long-term surveillance for endovascular leakage and other complications, resulting in an increased need for re-intervention.^31,33,35 For these reasons, the National Institute for Health and Care Excellence (NICE) guidelines suggest open repair as the preferred modality.⁷ However, SVS and the American College of Cardiology Foundation/American Heart Association guidance support either EVAR or open repair, noting that open repair may be preferable in patients unable to engage in long-term follow-up surveillance.³⁶

Indications for repair. In general, repair is indicated when an aneurysm reaches or exceeds 5.5 cm.^4,7 Both SVS and NICE also recommend clinicians consider surgical repair of smaller, rapidly expanding aneurysms (> 1 cm over a 1-year period).^4,7 Based on evidence suggesting a higher risk for rupture in women with smaller aneurysms,^14,37 SVS recommends clinicians consider surgical repair in women with an AAA ≥ 5.0 cm. Several RCTs evaluating the benefits of immediate repair for smaller-sized aneurysms (4.0-5.5 cm) favored surveillance.^38,39 Accepted indications for surgical repair are summarized in TABLE 3.^4,7,34Surgical repair recommendations also are based on aneurysm morphology, which can be fusiform or saccular (FIGURE). More than 90% of AAAs are fusiform.⁴⁰ Although saccular AAAs are less common, some studies suggest they are more prone to rupture than fusiform AAAs, and SVS guidelines suggest surgical repair of saccular aneurysms regardless of size.^4,41,42

Perioperative and long-term risks. Both EVAR and open repair of AAA carry a high perioperative and long-term risk for death, as patients often have multiple comorbidities. A 2019 trial comparing EVAR to open repair with 14 years of follow-up reported death in 68% of patients in the EVAR group and 70% in the open repair group. ³¹ Among these deaths, 2.7% in the EVAR group and 3.7% in the open repair group were aneurysm related.³¹ The study also found a second surgical intervention was required in 19.8% of patients in the open repair group and 26.7% in the EVAR group.³¹

Continue to: When assessing perioperative risk...

Although abdominal aortic aneurysms are more common in men, there is a 2- to 4-fold higher risk for rupture in women.

When assessing perioperative risk, SVS guidelines recommend clinicians employ a shared decision-making approach with patients that incorporates Vascular Quality Initiative (VQI) mortality risk score.⁴ (VQI risk calculators are available at https://qxmd.com/vascular-study-group-new-england-decision-support-tools.⁴³)

Medication management

Based on the close association of aortic aneurysm with atherosclerotic CVD (ASCVD), professional societies such as the European Society of Cardiology and European Atherosclerosis Society (ESC/EAS) have suggested aortic aneurysm is equivalent to ASCVD and should be managed medically in a similar manner to peripheral arterial disease.⁴⁴ Indeed, many patients with AAA may have concomitant CAD or other arterial vascular diseases (eg, carotid, lower extremity).

Statins. In its guidelines, the ESC/EAS consider patients with AAA at “very high risk” for adverse CV events and suggest pharmacotherapy with high-intensity statins, adding ezetimibe or proprotein convertase ­subtilisin/kexin type 9 (PCSK9) inhibitors if needed, to reduce low-density lipoprotein cholesterol ≥ 50% from baseline, with a goal of < 55 mg/dL.⁴⁴ Statin therapy additionally lowers all-cause postoperative mortality in patients undergoing AAA repair but does not affect the rate of aneurysm expansion.⁴⁵

Aspirin and other anticoagulants. Although aspirin therapy may be indicated for the secondary prevention of other cardiovascular events that may coexist with AAA, it does not appear to affect the rate of growth or prevent rupture of aneurysms.^46,47 In addition to aspirin, anticoagulants such as clopidogrel, enoxaparin, and warfarin are not recommended when the presence of AAA is the only indication.⁴

The USPSTF continues to recommend against screening in women with no smoking history and no family history of abdominal aortic aneurysm.

Other medications. Angiotensin-­converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, and antibiotics (eg, doxycycline) have been studied as a treatment for AAA. However, none has shown benefit in reducing aneurysm growth or rupture and they are not recommended for that sole purpose.^4,48

Metformin. There is a negative association between diabetes and AAA expansion and rupture. Several cohort studies have indicated that this may be an independent effect driven primarily by exposure to metformin. While it is not unreasonable to consider this another important indication for metformin use in patients with diabetes, RCT evidence has yet to establish a role for metformin in patients without diabetes who have AAA.^48,49

Ruptured abdominal aortic aneurysms (AAAs) caused about 6000 deaths annually in the United States between 2014 and 2020¹ and are associated with a pooled mortality rate of 81%.² They result from a distinct degenerative process of the layers of the aortic wall.² An AAA is defined as an abdominal aorta whose dilation is > 50% normal (more commonly, a diameter > 3 cm).^3,4 The risk for rupture correlates closely with size; most ruptures occur in aneurysms > 5.5 cm^3,4 (TABLE 1⁵).

Most AAAs are asymptomatic and often go undetected until rupture, resulting in poor outcomes. Because of a low and declining prevalence of AAA and ruptured AAA in developed countries, screening recommendations target high-risk groups rather than the general population.^4,6-8 This review summarizes risk factors, prevalence, and current evidence-based screening and management recommendations for AAA.

Who’s at risk?

Age is the most significant nonmodifiable risk factor, with AAA rupture uncommon in patients younger than 55 years.⁹ One retrospective study found the odds ratio (OR) for diagnosing AAA was 9.41 in adults ages 65 to 69 years (95% CI, 8.76-10.12; P < .0001) and 14.46 (95% CI, 13.45-15.55; P < .0001) in adults ages 70 to 74 years, compared to adults younger than 55 years.¹⁰

Smoking is the most potent modifiable risk factor for AAA. Among patients with AAA, > 90% have a history of smoking.⁴ The association between smoking and AAA is dose dependent, with an OR of 2.61 (95% CI, 2.47-2.74) in patients with a pack-per-year history < 5 years and 12.13 (95% CI, 11.66-12.61) in patients with a pack-per-year history > 35 years, compared to nonsmokers.¹⁰ The risk for AAA increases with smoking duration but decreases with cessation duration.^4,10 Smoking cessation remains an important intervention, as active smokers have higher AAA rupture rates.¹¹

Other risk factors for AAA include concomitant cardiovascular disease (CVD) such as coronary artery disease (CAD), cerebrovascular disease, atherosclerosis, dyslipidemia, and hypertension.¹⁰ Factors associated with reduced risk for AAA include African American race, Hispanic ethnicity, Asian ethnicity, diabetes, smoking cessation, consuming fruits and vegetables > 3 times per week, and exercising more than once per week.^6,10

Prevalence declines but sex-based disparities in outcomes persist

The prevalence of AAA has declined in the United States and Europe in recent decades, correlating with declining rates of smoking.^4,12 Reports published between 2011 and 2019 estimate that AAA prevalence in men older than 60 years has declined over time, with a prevalence of 1.2% to 3.3%.⁶ The prevalence of AAA has also decreased in women,^6,13,14 estimated in 1 study to be as low as 0.74%.¹³ Similarly, deaths from ruptured AAA have declined markedly in the United States—by 70% between 1999 and 2016 according to 1 analysis.⁹

One striking difference in the male-female data is that although AAAs are more common in men, there is a 2- to 4-fold higher risk for rupture in women, who account for nearly half of all AAA-related deaths.^9,10,15-17 The reasons for this heightened risk to women despite lower prevalence are not fully understood but are likely multifactorial and related to a general lack of screening for AAA in women, tendency for AAA to rupture at smaller diameters in women, rupture at an older age in women, and a history of worse surgical outcomes in women than men (though the gap in surgical outcomes appears to be closing).^9,10,18

CASE Sexually active woman asks about the HPV vaccine

A 26-year-old woman delivered her first child 4 weeks ago. She has had 3 lifetime sexual partners and is now in a mutually faithful monogamous relationship with her partner. She has no known history of sexually transmissible infections. She received only one Pap test 3 years ago, and the cytology showed no abnormal cells. This cervical specimen was not tested for human papillomavirus (HPV) DNA. At the time of her postpartum appointment, she inquires whether she is a candidate for the HPV vaccine.

What should be your response?
 

Genital HPV infection is the most common sexually transmissible infection in the United States. This virus is the cause of multiple genital malignancies, including cancers of the vagina, vulva, penis, anus, and cervix. The organism is also now the major cause of oropharyngeal cancer.

Of the more than 200 different HPV types that have been identified, 12 have been defined as oncogenic (high risk), and 8 to 12 types have been defined as possibly or probably oncogenic. The HPV strain with the highest risk of progression to cancer is HPV 16. The strains HPV 16 and 18 are responsible for approximately 70% of cases of cervical cancer. Each year in the United States, approximately 11,500 new cases of invasive cervical cancer occur. Unfortunately, this malignancy is responsible for about 4,000 deaths annually. Worldwide, HPV causes approximately 690,000 cancers each year.¹

To a large extent, most cases of HPV infection would be preventable if patients were to take advantage of the remarkably effective HPV vaccine that is now available. However, acceptance of the vaccine has been disappointing. In 2020, only about half of adolescents, age 13 to 15, had received the appropriate number of vaccine doses.¹

As ObGyn physicians, we can take several measures, in concert with our pediatrician colleagues, to improve HPV vaccination rates. In this article, I review the development of the HPV vaccine and describe the components, indications, dosing schedules, contraindications, adverse effects, and cost of the vaccine.

HPV vaccine development and expansion

The first HPV vaccine introduced in the United States was the recombinant quadrivalent vaccine (Gardasil; Merck); it was approved by the US Food and Drug Administration (FDA) in 2006. This vaccine is composed of viral-like particles unique to HPV 16 and 18 (the 2 most common causes of cervical, penile, anal, and oropharyngeal cancer) and HPV 6 and 11 (the 2 most common causes of genital warts). The formulation is prepared in baker’s yeast, and it elicits a robust production of neutralizing antibodies.²

In 2009, the FDA approved the bivalent vaccine (Cervarix; GlaxoSmithKline Biologicals). This vaccine contains viral-like particles unique to HPV 16 and 18, and it also induces a robust immune response. The vaccine is prepared in insect viral vectors.²

Both the quadrivalent and bivalent vaccines are no longer available in the United States. The only HPV vaccine currently marketed is the recombinant 9-valent vaccine (Gardasil 9; Merck), which was approved by the FDA in 2014. This newer vaccine targets the original 4 viral HPV strains in the quadrivalent vaccine (16, 18, 6, 11) plus 5 additional oncogenic strains: 31, 33, 45, 52, 58.^2-4 The HPV strains targeted by this vaccine are responsible for approximately 90% of all cancers caused by HPV.

The 9-valent HPV vaccine, like the other 2, is highly effective in preventing cancers of the cervix, vagina, vulva, anus, penis; oropharyngeal cancers; and precancerous lesions such as genital warts.^2-5 It will not, however, prevent the progression of preexisting infection or clear an infection that is already present at the time of vaccination.¹

Although the original protocol for administration of the vaccine provided for 3 doses, recent studies indicate that 2 doses may be as effective as 3 in eliciting a favorable antibody response.⁶ There also is evidence that even a single dose of the vaccine can elicit a protective immune response.⁷ This encouraging finding is particularly important to public health officials responsible for developing HPV vaccination programs in low- and middle-resource countries.

Continue to: Target groups for the HPV vaccine...

Target groups for the HPV vaccine

The primary target group for the HPV vaccine is girls and boys who are aged 11 to 12 years. The key strategy is to immunize these individuals before they become sexually active. The vaccine also should be offered to children who are aged 9 to 10 years of age if they are judged to be at unusual risk, such as because of concern about sexual molestation. Children in these 2 age groups should receive 2 doses of the vaccine, with the second dose administered 6 to 12 months after the first dose.

The second target group for vaccination is individuals who are aged 13 to 26 years who have never been vaccinated. They should be offered catch-up vaccination. If older than age 15, they should receive 3 doses of the vaccine, with the second dose administered 1 to 2 months after the first dose and the third dose administered 6 months after the first dose.¹

A third target group is individuals who are aged 27 to 45 years and who, in their own opinion or in the opinion of their physician, are at new or increased risk for HPV infection. These individuals should receive the 3-dose vaccine series as outlined above.¹

Patients in any age range who are immunocompromised, for example, due to HIV infection, should receive the 3-dose series.¹

The approximate retail cost of a single 0.5-mL intramuscular dose of the 9-valent vaccine is $240 (www.goodrx.com).

Vaccine adverse effects

The most common reactions to the HPV vaccine are inflammation at the site of injection, fatigue, headache, fever, gastrointestinal upset, vertigo, cough, and oropharyngeal discomfort. The most serious reaction—which fortunately is very rare—is anaphylaxis.¹

Contraindications to the vaccine

The HPV vaccine should not be used in any patient who is hypersensitive to any component of the vaccine, including yeast. It should not be given to a patient who is moderately or severely ill at the time of the scheduled administration. Because of an abundance of caution, the manufacturer also recommends that the vaccine not be given to pregnant women even though the agent does not contain live virus.¹

Of note, a study by Scheller and colleagues was very reassuring about the lack of adverse effects of HPV vaccine administration in pregnancy.⁸ The authors evaluated a large cohort of pregnant women in Demark and found that exposure to the vaccine was not associated with an increase in the frequency of major birth defects, spontaneous abortion, preterm delivery, low birthweight, fetal growth restriction, or stillbirth.⁸

Barriers to vaccination

One important barrier to HPV vaccination is patient apprehension that the vaccine may cause genital tract or oropharyngeal cancer. The patient should be reassured that the vaccine does not contain infectious viral particles and does not transmit infection. Rather, it builds robust immunity to infection.

Another important barrier is the misconception that the vaccine will promote sexual promiscuity in preteenagers and teenagers. Absolutely no evidence supports this belief. Multiple studies have demonstrated that teenagers do not engage in more high-risk sexual behavior following vaccination.

A specific barrier related to vaccination of young boys is the philosophical viewpoint that, “Why should my young male child be vaccinated to protect against a disease (specifically cervical cancer) that occurs only in girls and women?” The appropriate answer to this question is that the vaccine also protects against penile cancer, anal cancer, oropharyngeal cancer, and genital warts. While penile and anal cancers are rare, the other 2 conditions are not. In fact, oropharyngeal cancer is significantly more common in males than females.

A final important barrier to HPV vaccination is cost. The new evidence that demonstrated the effectiveness of a 2-dose vaccine series, and even single-dose vaccination, is of great importance in minimizing cost of the HPV vaccine series, in the absence of full reimbursement by public and private insurance agencies.

Creating an effective vaccination program

The following commonsense guidelines, which we have implemented at our medical center, should be helpful in organizing an effective HPV vaccination program for your office or department^4,9,10:

• One clinician in the department or practice should be designated the “vaccination champion.” This individual should provide colleagues with periodic updates, emphasizing the importance of the HPV vaccine and other vaccines, such as Tdap (tetanus, diphtheria, pertussis), influenza, COVID, pneumococcal, hepatitis B, herpes zoster (shingles), and RSV (respiratory syncytial virus).
• One staff member in the practice or department should be designated as the go-to person for all logistical matters related to vaccines. This individual should be responsible for estimating usage, ordering vaccines, and storing them properly. He or she also should be knowledgeable about the cost of the vaccines and insurance reimbursement for the vaccines.
• Signs and educational materials should be posted in strategic locations in the office, advising patients of the importance of timely vaccination for themselves and their adolescent children.
• At every encounter, patients should be encouraged to receive the HPV vaccine series if they are in the appropriate age range and social situation for vaccination. They should not be required to have HPV testing before vaccine administration.
• Key leaders in the department or practice should lobby effectively with their pediatrician colleagues and with public and private insurance companies to encourage timely administration and proper coverage of this important immunization.

Other measures to reduce the risk of HPV-mediated malignancies

Practitioners should advise their patients to:

• Be circumspect in selection of sexual partners.
• Use male or female condoms when engaging in vaginal, anal, and/or oral sex with multiple partners, particularly those who may have genital or oral condylomas.
• Have regular Pap tests, every 3 to 5 years, depending upon age. More frequent testing may be indicated if there is a history of previous abnormal testing.
• Seek prompt medical or surgical treatment for genital or oral condylomas.

CASE Resolved with HPV vaccination

This patient is an excellent candidate for catch-up vaccination. She should receive the first dose of the 9-valent HPV vaccine at the time of her postpartum appointment. The second dose should be administered 1 to 2 months later. The third dose should be administered 6 months after the first dose. She also should have a Pap test, either cytology alone or cytology plus HPV screening. If the latter test is chosen and is reassuring, she will not need retesting for 5 years. If the former test is chosen, she should have a repeat test in 3 years. ●

CASE Sexually active woman asks about the HPV vaccine

A 26-year-old woman delivered her first child 4 weeks ago. She has had 3 lifetime sexual partners and is now in a mutually faithful monogamous relationship with her partner. She has no known history of sexually transmissible infections. She received only one Pap test 3 years ago, and the cytology showed no abnormal cells. This cervical specimen was not tested for human papillomavirus (HPV) DNA. At the time of her postpartum appointment, she inquires whether she is a candidate for the HPV vaccine.

What should be your response?
 

Genital HPV infection is the most common sexually transmissible infection in the United States. This virus is the cause of multiple genital malignancies, including cancers of the vagina, vulva, penis, anus, and cervix. The organism is also now the major cause of oropharyngeal cancer.

Of the more than 200 different HPV types that have been identified, 12 have been defined as oncogenic (high risk), and 8 to 12 types have been defined as possibly or probably oncogenic. The HPV strain with the highest risk of progression to cancer is HPV 16. The strains HPV 16 and 18 are responsible for approximately 70% of cases of cervical cancer. Each year in the United States, approximately 11,500 new cases of invasive cervical cancer occur. Unfortunately, this malignancy is responsible for about 4,000 deaths annually. Worldwide, HPV causes approximately 690,000 cancers each year.¹

To a large extent, most cases of HPV infection would be preventable if patients were to take advantage of the remarkably effective HPV vaccine that is now available. However, acceptance of the vaccine has been disappointing. In 2020, only about half of adolescents, age 13 to 15, had received the appropriate number of vaccine doses.¹

As ObGyn physicians, we can take several measures, in concert with our pediatrician colleagues, to improve HPV vaccination rates. In this article, I review the development of the HPV vaccine and describe the components, indications, dosing schedules, contraindications, adverse effects, and cost of the vaccine.

HPV vaccine development and expansion

The first HPV vaccine introduced in the United States was the recombinant quadrivalent vaccine (Gardasil; Merck); it was approved by the US Food and Drug Administration (FDA) in 2006. This vaccine is composed of viral-like particles unique to HPV 16 and 18 (the 2 most common causes of cervical, penile, anal, and oropharyngeal cancer) and HPV 6 and 11 (the 2 most common causes of genital warts). The formulation is prepared in baker’s yeast, and it elicits a robust production of neutralizing antibodies.²

In 2009, the FDA approved the bivalent vaccine (Cervarix; GlaxoSmithKline Biologicals). This vaccine contains viral-like particles unique to HPV 16 and 18, and it also induces a robust immune response. The vaccine is prepared in insect viral vectors.²

Both the quadrivalent and bivalent vaccines are no longer available in the United States. The only HPV vaccine currently marketed is the recombinant 9-valent vaccine (Gardasil 9; Merck), which was approved by the FDA in 2014. This newer vaccine targets the original 4 viral HPV strains in the quadrivalent vaccine (16, 18, 6, 11) plus 5 additional oncogenic strains: 31, 33, 45, 52, 58.^2-4 The HPV strains targeted by this vaccine are responsible for approximately 90% of all cancers caused by HPV.

The 9-valent HPV vaccine, like the other 2, is highly effective in preventing cancers of the cervix, vagina, vulva, anus, penis; oropharyngeal cancers; and precancerous lesions such as genital warts.^2-5 It will not, however, prevent the progression of preexisting infection or clear an infection that is already present at the time of vaccination.¹

Although the original protocol for administration of the vaccine provided for 3 doses, recent studies indicate that 2 doses may be as effective as 3 in eliciting a favorable antibody response.⁶ There also is evidence that even a single dose of the vaccine can elicit a protective immune response.⁷ This encouraging finding is particularly important to public health officials responsible for developing HPV vaccination programs in low- and middle-resource countries.

Continue to: Target groups for the HPV vaccine...

Target groups for the HPV vaccine

The primary target group for the HPV vaccine is girls and boys who are aged 11 to 12 years. The key strategy is to immunize these individuals before they become sexually active. The vaccine also should be offered to children who are aged 9 to 10 years of age if they are judged to be at unusual risk, such as because of concern about sexual molestation. Children in these 2 age groups should receive 2 doses of the vaccine, with the second dose administered 6 to 12 months after the first dose.

The second target group for vaccination is individuals who are aged 13 to 26 years who have never been vaccinated. They should be offered catch-up vaccination. If older than age 15, they should receive 3 doses of the vaccine, with the second dose administered 1 to 2 months after the first dose and the third dose administered 6 months after the first dose.¹

A third target group is individuals who are aged 27 to 45 years and who, in their own opinion or in the opinion of their physician, are at new or increased risk for HPV infection. These individuals should receive the 3-dose vaccine series as outlined above.¹

Patients in any age range who are immunocompromised, for example, due to HIV infection, should receive the 3-dose series.¹

The approximate retail cost of a single 0.5-mL intramuscular dose of the 9-valent vaccine is $240 (www.goodrx.com).

Vaccine adverse effects

The most common reactions to the HPV vaccine are inflammation at the site of injection, fatigue, headache, fever, gastrointestinal upset, vertigo, cough, and oropharyngeal discomfort. The most serious reaction—which fortunately is very rare—is anaphylaxis.¹

Contraindications to the vaccine

The HPV vaccine should not be used in any patient who is hypersensitive to any component of the vaccine, including yeast. It should not be given to a patient who is moderately or severely ill at the time of the scheduled administration. Because of an abundance of caution, the manufacturer also recommends that the vaccine not be given to pregnant women even though the agent does not contain live virus.¹

Of note, a study by Scheller and colleagues was very reassuring about the lack of adverse effects of HPV vaccine administration in pregnancy.⁸ The authors evaluated a large cohort of pregnant women in Demark and found that exposure to the vaccine was not associated with an increase in the frequency of major birth defects, spontaneous abortion, preterm delivery, low birthweight, fetal growth restriction, or stillbirth.⁸

Barriers to vaccination

One important barrier to HPV vaccination is patient apprehension that the vaccine may cause genital tract or oropharyngeal cancer. The patient should be reassured that the vaccine does not contain infectious viral particles and does not transmit infection. Rather, it builds robust immunity to infection.

Another important barrier is the misconception that the vaccine will promote sexual promiscuity in preteenagers and teenagers. Absolutely no evidence supports this belief. Multiple studies have demonstrated that teenagers do not engage in more high-risk sexual behavior following vaccination.

TOPLINE:

Direct health care costs for patients with vitiligo eclipse those of matched control persons.

METHODOLOGY:

• No published studies have quantified the medical costs and health care resource utilization (HCRU) among patients with vitiligo in the United States, compared with the general population.
• Drawing from the Merative MarketScan Commercial Claims and Encounters database, researchers reviewed the records of 49,512 patients diagnosed with vitiligo between Jan. 1, 2008, and Dec. 31, 2020, and those of 99,024 matched control persons who did not have vitiligo.
• Costs were in 2021 dollars during a 1-year postindex period. The student t test and chi square analysis were used to determine P values.

TAKEAWAY:

• In both cohorts, the median age of patients was 43 years, 79.2% were female, and most (39%) were from the southern region of the United States.
• All-cause total health care costs for patients with vitiligo were significantly higher than those of matched controls ($15,551 vs. $7,735; P < .0001).
• Similarly, medical costs for patients with vitiligo were significantly higher than those of control persons ($11,953 vs. $5,722), as were pharmacy costs ($3,598 vs. $2,014; P < .001 for both associations).
• A significantly greater proportion of patients with vitiligo had higher all-cause HCRU, compared with matched control persons. That included at least one ED visit (17.5% vs 13.4%), at least one inpatient visit (12.9% vs 6.8%), and at least one outpatient visit (99.8% vs. 88.3%; P < .0001 for all associations).

IN PRACTICE:

“These findings reveal an unmet need for cost-effective treatments and highlight the importance of fully identifying the drivers of economic burden for patients with vitiligo,” the authors concluded.

SOURCE:

Khaled Ezzedine, MD, PhD, of the department of dermatology at the Henri Mondor University Hospital, Créteil, France, led the study, which was published in the Journal of Investigative Dermatology.

LIMITATIONS:

The investigators did not evaluate indirect medical costs of vitiligo, such as work productivity, early retirement, and lost opportunities. Also, the results may not be generalizable to populations outside of the United States.

DISCLOSURES:

Dr. Ezzedine has received honoraria as a consultant for AbbVie, Incyte, La Roche–Posay, Pfizer, Pierre Fabre, Sanofi, and Viela Bio. One author is an investigator for Incyte and is a consultant for several pharmaceutical companies. Three authors are AbbVie employees.

TOPLINE:

Among pediatric patients with psoriasis, Black children and male children are significantly more likely to have palmoplantar psoriasis.

METHODOLOGY:

• Researchers reviewed data on 330 children and youths aged 0-18 years who had received a primary psoriasis diagnosis and who were seen at an academic pediatric dermatology clinic from 2012 to 2022. Among these patients, 50 cases of palmoplantar psoriasis (PP) were identified by pediatric dermatologists.
• The study population was stratified by race/ethnicity on the basis of self-identification. The cohort included White, Black, and Hispanic/Latino patients, as well as patients who identified as other; 71.5% were White persons, 59.1% were female patients.
• The researchers used a regression analysis to investigate the association between race/ethnicity and PP after controlling for multiple confounding variables, including age and gender.

TAKEAWAY:

• Black children were significantly more likely to have PP than White children (adjusted odds ratio, 6.386; P < .0001). PP was diagnosed in 41.9%, 11.5%, and 8.9% of Black, Hispanic/Latino, and White children, respectively.
• Male gender was also identified as an independent risk factor for PP (aOR, 2.241).
• Nail involvement occurred in significantly more Black and Hispanic/Latino patients than in White patients (53.2%, 50.0%, and 33.9%, respectively).
• Black patients had significantly more palm and sole involvement, compared with the other groups (P < .0001 for both); however, White children had significantly more scalp involvement, compared with the other groups (P = .04).

IN PRACTICE:

“Further research is warranted to better understand the degree to which these associations are affected by racial disparities and environmental factors,” as well as potential genetic associations, the researchers noted.

SOURCE:

The corresponding author on the study was Amy Theos, MD, of the department of dermatology at the University of Alabama, Birmingham. The study was published online in Pediatric Dermatology.

LIMITATIONS:

The findings were limited by the small sample size and incomplete data for some patients.

DISCLOSURES:

The study received no outside funding. The researchers had no financial conflicts to disclose.

TOPLINE:

Among pediatric patients with psoriasis, Black children and male children are significantly more likely to have palmoplantar psoriasis.

METHODOLOGY:

• Researchers reviewed data on 330 children and youths aged 0-18 years who had received a primary psoriasis diagnosis and who were seen at an academic pediatric dermatology clinic from 2012 to 2022. Among these patients, 50 cases of palmoplantar psoriasis (PP) were identified by pediatric dermatologists.
• The study population was stratified by race/ethnicity on the basis of self-identification. The cohort included White, Black, and Hispanic/Latino patients, as well as patients who identified as other; 71.5% were White persons, 59.1% were female patients.
• The researchers used a regression analysis to investigate the association between race/ethnicity and PP after controlling for multiple confounding variables, including age and gender.

TAKEAWAY:

• Black children were significantly more likely to have PP than White children (adjusted odds ratio, 6.386; P < .0001). PP was diagnosed in 41.9%, 11.5%, and 8.9% of Black, Hispanic/Latino, and White children, respectively.
• Male gender was also identified as an independent risk factor for PP (aOR, 2.241).
• Nail involvement occurred in significantly more Black and Hispanic/Latino patients than in White patients (53.2%, 50.0%, and 33.9%, respectively).
• Black patients had significantly more palm and sole involvement, compared with the other groups (P < .0001 for both); however, White children had significantly more scalp involvement, compared with the other groups (P = .04).

IN PRACTICE:

“Further research is warranted to better understand the degree to which these associations are affected by racial disparities and environmental factors,” as well as potential genetic associations, the researchers noted.

A 16-year-old female presents for a self-identified concern around the possibility that she is experiencing an autism spectrum disorder. She relays to the developmental pediatrician that she has been learning a lot about autism on TikTok and through other social media sites, and has become strongly convinced that she meets medical criteria for this disorder.

Oregon Health &amp; Science University (OHSU)

A careful developmental history via a detailed interview with the mother reveals normal acquisition of early developmental milestones in addition to long-standing well-modulated eye contact felt to be paired fluidly with directed affect and gestures. The teen is described as having been an engaging toddler and preschooler, without restricted interests or repetitive behaviors, and having had no major challenges in grade school with behaviors, friendships, or academics.

During the pandemic, however, the teen became quite isolated. She developed anxiety with depression, and then started having some new repetitive arm movements within the last 12-18 months. In clinic, the teen makes robustly effortful arm-waving movements, which are noted to wane when she becomes more animated and excited during conversation, and to increase when she is less distracted by conversation and more focused on the movements.

She directs affect nicely toward her mother, while avoiding looking in the direction of the examiner until later in the evaluation when she becomes more relaxed. Prosody of speech and intonation are typical, and she describes having a close group of friends with whom she spends quite a bit of time.

The Autism Diagnostic Observation Schedule (ADOS-2 module 3) is used to gather structured observations, and these social presses yield flowing social engagement with the examiner, good understanding of humor, and overall excellent verbal and nonverbal communication skills. The teen describes hypervigilance around the emotions of others, a natural ease in understanding the perspectives of others, and a quick ability to read the energy of a room. She does have some interest in some more obscure online game forums, but her friends do as well, and she otherwise does not have a history of intrusive fixations. A social history reveals past significant verbal abuse in the home by means of her father during her first 11 years of life, which is described as quite traumatic.

After careful and thoughtful consideration (recognizing the known statistics around girls assigned female at birth, as well as nonbinary individuals and minoritized groups being underdiagnosed with autism), the history and observations are not felt to be consistent with autism, but with anxiety within the context of a trauma and stressor-related disorder. Even when accounting for the possibility of “masking,” the teen still does not meet criteria for autism based on history and presentation. The habit movements are not typical of usual stereotypies or of tics (which tend to increase with excitement and tend to have a more effortless quality), and are felt to possibly be functional in origin. Upon gently sharing these conclusions with the teen, she bursts into tears, stating her friends may now accuse her of lying, as she has already been claiming to have autism online and in person at school.
 

Countering social media diagnoses

This type of scenario is becoming increasingly common, with teens turning online primarily to social media accounts to gain knowledge around various neurologic and mental health conditions. Greater normalization of neurodiversity and greater access to high-quality information about neurodevelopmental differences is certainly progress, though unfortunately some online depictions of these conditions are simply not accurate. Many adolescents are keenly searching for both their personal identity and also a community through which they might feel wholly accepted, after experiencing some level of isolation during the pandemic followed by increased social discomfort in attempting to reintegrate into school life and society. It is important to take time to understand the drive behind an adolescent’s apparent desire for a specific diagnosis, particularly if that diagnosis is not felt to be an accurate conceptualization of the teen’s presentation by a skilled professional. Connecting the teen with a good-fit therapist and working to replace excessive screen time with exercise, outdoor activities, and in-person engagement with friends and family are also crucial interventions, though they can be incredibly difficult for families to achieve given various patient-specific and societal barriers. The overlap in symptomatology among anxiety, attention-deficit/hyperactivity disorder, and autism spectrum disorders is expansive, making it understandable that young people might misjudge their personal experience of life for a neurodevelopmental disorder for which they do not truly meet criteria. Increasing access to therapists well versed in trauma-informed care is a frequently referenced need, highlighted in this case.

Another case

In contrast to the case scenario above is that of a 19-year-old female presenting for a formal autism evaluation at the urging of her father, who has had concerns around her severe “shyness” throughout her life. He is concerned that she was not able to obtain a high school diploma despite appearing to have adequate cognitive skills, is currently quite isolated, and does not appear equipped to hold a job at this time. He describes her as having been a very quiet and self-directed young child who greatly benefited from the communication and social scaffolding provided by her slightly older and neurotypical sister. She has generally not had true friends, though she had no behavioral or academic difficulties in school other than seeming aloof and unusually quiet. Atypical social approaches have become more apparent over time, as relationship navigation has become more complex with age. She is noted to have frequent stereotyped hand-to-face movements throughout the evaluation, as well as a flat affect and unusual voice quality. She speaks slowly and softly, and while she does make eye contact, it is less well modulated than would be expected. She is very focused on her cat and online interests during conversation, and tends to give stilted answers to open-ended questions. During the interview portion of the ADOS, she demonstrates little insight into friendships and reports feeling very content on her own, though is open to the idea of relationships in the future and would like to learn how to achieve connections with others. Her father reports she tends to be generally quite blunt and has difficulty understanding humor and others’ perspectives. An autism diagnosis is made with the recommendation of application to Developmental Disability Services, given impaired adaptive skills, as a means of utilizing community-based supports to facilitate eventually obtaining a high school equivalency credential, a job, healthier living habits, and comfortable social outlets.

Discussion

It is crucial for providers to be aware of nuanced presentations of autism spectrum disorders that may have been missed in early childhood when social demands are less complicated, particularly in persons identified as female at birth, nonbinary individuals, and those belonging to minority groups. It is also important to address the widely acknowledged trend of adolescents turning to social media influencers for information around neurodevelopmental conditions, at a time in their lives when social anxiety and self-awareness are generally heightened. For an adolescent, a young social media influencer may feel like a more salient and reliable source of information than an adult with various letters after their name. A respectful relationship between a teen and a thoughtful primary care provider can help gain trust to foster open conversations around their concerns, which can further help determine if a referral to a psychologist or developmental pediatrician for a formal autism assessment is truly warranted, highlighting the need for increased diagnostic capacity for such. While it is certainly important for providers to keep an open mind and to have continued awareness around the concept of late autism diagnoses, it is wise to also be aware of this recent trend among adolescents as providers seek to guide youth toward appropriate therapies and services.

A fixed drug eruption (FDE) is a rare cutaneous and/or mucosal reaction caused by ingestion of a drug. This is a delayed hypersensitivity reaction in which lesions present in the same location upon repeated intake of the offending drug. The lesions typically present within 30 minutes to 8 hours of administration of the drug. These reactions can be considered allergic or pseudo-allergic, in which case, there is no notable adaptive immune response. CD8+ T cells appear to play a role in the epidermal injury via release of interferons and interactions with other inflammatory cells.

There are numerous drugs that can precipitate these findings. NSAIDs; antibiotics, such as tetracyclines, sulfonamides; and phenytoin are common offenders. In the case of our patient, naproxen was the offending medication.

The classic presentation of FDE features annular, erythematous to violaceous macules on the skin or mucosa that can be asymptomatic or can produce burning, pain, or pruritus. The most common locations include the trunk and extremities, but the palms, soles, face, scalp, and mucosa can also be impacted. The oral mucosa seems to be the most common mucosal location. Intravenous administration of a drug is associated with more severe symptoms. Systemic symptoms are typically absent, and the eruption may initially be in one location, but may appear elsewhere upon repeated exposure to the offending medication.

The differential diagnosis includes arthropod bite reactions, urticaria, and erythema multiforme. Although FDEs are typically a clinical diagnosis, the histopathology will commonly show a vacuolar interface dermatitis. Furthermore, a variety of immune cells can be found, including neutrophilic, eosinophilic, and lymphocytic infiltrate. A combination of two or more histological patterns often favors the diagnosis of FDE.

Steroid creams can be prescribed to decrease the inflammatory reaction and improve symptoms; however, the definitive treatment of this condition is cessation of the offending agent. Postinflammatory hyperpigmentation is a common symptom after resolution of the condition, and it may take months to fade away. Further darkening can be prevented by practicing sun safety measures such as wearing sunblock, covering the affected areas, and avoiding prolonged sun exposure.

They estimated that, among 50-year-olds, life expectancy of those diagnosed with type 2 diabetes at age 30 is 14 years shorter than that of their peers without diabetes. Among those diagnosed at age 50, life expectancy is 6 years shorter.

The study was recently published in The Lancet – Diabetes and Endocrinology.

The team analyzed data from the Emerging Risk Factors Collaboration and the UK Biobank. The data were from 97 long-term, prospective cohorts and involved 1.5 million participants who were followed for 23.1 million person-years.

“The strongest associations with earlier age at diagnosis of diabetes were for vascular (for example, myocardial infarction and stroke) and other causes of death – mainly respiratory, neurological, and infectious diseases and external causes,” they reported.

Their findings are consistent with previous studies that suggested that younger individuals who develop type 2 diabetes might have higher body mass index (BMI), blood pressure, and lipid levels and that they might experience faster deterioration in glycemic control than individuals who develop diabetes later, potentially leading to premature mortality.

Asked to comment, Anne Peters, MD, director of clinical diabetes programs at the University of Southern California, Los Angeles, who was not involved with this study, said: “We’ve long known that diabetes reduces life expectancy, and the younger you get it the more years you lose. However, this study was from a broader and larger population base than prior studies.

“In this study, the major reason for death was vascular disease, and undertreatment of cardiovascular risk factors may have occurred in the younger individuals. We also don’t know about glucose control.

“I personally think the findings show that we should treat cardiovascular risk factors more aggressively in people diagnosed with [type 2] diabetes in their 30s and 40s,” urged Dr. Peters.
 

High priority should be given to prevention globally

“Type 2 diabetes used to be seen as a disease that affected older adults, but we’re increasingly seeing people diagnosed earlier in life,” senior author Emanuele Di Angelantonio, MD, PhD, from the University of Cambridge (England), explained in a press release. “As we’ve shown, this means they are at risk of a much shorter life expectancy than they would otherwise have.”

The findings suggest that “high priority should be given to developing and implementing interventions that prevent or delay the onset of [type 2 diabetes], especially as its prevalence among younger age groups is increasing globally,” the study authors wrote.

The results “support the idea that the younger an individual is when they develop type 2 diabetes, the more damage their body accumulates from its impaired metabolism,” added co–senior author Naveed Sattar, MD, PhD, of the University of Glasgow,

Dr. Peters agreed: “People who develop type 2 diabetes at a younger age might have a different, potentially more aggressive type of type 2 diabetes and perhaps need treatment targets that are lower than people who develop type 2 diabetes when they are older.”

“The findings ... suggest that early detection of diabetes by screening followed by intensive glucose management could help prevent long-term complications from the condition,” Dr. Sattar said.

Dr. Peters added: “An issue for some is pregnancy. ... Many of the medications taken for management of CVD [cardiovascular disease] risk factors are contraindicated in pregnancy (as are many of the medications [for treating type 2 diabetes]).

“We need to be careful to risk reduce but take care of the ‘whole person,’ and if of childbearing age, consider the safest approaches to healthy management,” she emphasized.
 

Study results: Type 2 diabetes diagnosed at age 30, 40, and 50

Previous studies estimated that adults with type 2 diabetes die 6 years earlier on average in comparison with their counterparts who do not have diabetes, but it was not known how diabetes duration affects life span.

To investigate this, the team analyzed individual records from the Emerging Risk Factors Collaboration and the UK Biobank. The primary outcome was all-cause mortality. Other outcomes were deaths from CVD, cancer, and other causes.

Over a median follow-up of 12.5 years, there were 246,670 deaths: 84,443 from cardiovascular causes, 150, 972 from noncardiovascular causes, and 11,255 from unknown/ill-defined causes.

Compared with participants who did not have a history of type 2 diabetes, the hazard ratios for all-cause mortality, adjusted for age and sex, were 2.69 for participants diagnosed at age 30-39, 2.26 for those diagnosed aged 40-49, 1.84 aged 50-59, 1.57 for those aged 60-69, and 1.39 for those diagnosed 70 and older.

These hazard ratios were similar after adjusting for BMI, systolic blood pressure, and total cholesterol, but they were substantially attenuated after further adjusting for fasting glucose or hemoglobin A1c level.

Similar patterns were observed for cause-specific mortality.

“Every decade of earlier diagnosis of diabetes was associated with about 3-4 years of lower life expectancy, highlighting the need to develop and implement interventions that prevent or delay the onset of diabetes and to intensify the treatment of risk factors among young adults diagnosed with diabetes,” the researchers wrote.

The study was funded the British Heart Foundation, the Medical Research Council, the National Institute for Health and Care Research, and Health Data Research UK. Dr. Peters is on advisory boards for Vertex, Eli Lilly, and Medscape, receives research funding from Abbott Diabetes Care and Insulet, and has stock options for Omada Health.

This transcript has been edited for clarity.

The other day, I received a flowery, elaborate email from none other than a physician recruiter: “Beautiful parks, hiking, great schools, blah blah blah, worked RVU production bonus on top of base pay.”

That last part – RVUs. I’m lost. I hear mixed reviews from physicians who work in RVU-based systems. The entire thing seems overly complex and confusing, so let’s clear it up. I did my research, and I’m going to explain RVUs.
 

Types of RVUs

RVUs, or relative value units, are a standard set by Medicare, used to measure physician productivity and ultimately determine compensation. There are three types:

• Work RVUs (basically everything that happens during a patient encounter).
• Practice expense RVUs.
• Professional liability insurance RVUs.

Now, envision this equation. All three of those RVUs are each multiplied by a geographic practice cost index to come up with a total number, and then that is multiplied by the Medicare conversion factor, which right now is around $33 to $34, to come up with a total dollar amount.

Work RVUs make up the bulk of total RVUs and they get their value from CPT codes. That value is determined by CMS. The AMA’s Relative Value Scale Update Committee, or RUC, which is made up of 32 people from various medical and surgical subspecialties, regularly meets and makes recommendations on the value of various CPT codes.
 

Is specialty representation fair and balanced?

CMS historically has accepted a high percentage of RUC’s recommendations, so this is a very influential committee. This is also why RUC has led to some controversy, with some stating that there is a lack of primary care representation, and perhaps this is why CPT codes related to procedures tend to reimburse higher.

How does one weigh the value of an hour-long palliative conversation against the quick removal of a benign skin lesion? That’s a loaded question.

Knowing the ins and outs of RVUs can help you understand how your productivity is being measured. This is especially important if your salary, or at least part of it, is determined by total RVUs. You want to have a sense of the pros and cons of working in an RVU system and how this relates to your specialty, your practice, and your schedule.

An RVU-based system provides an objective measure on complex patient encounters, volume, and procedures, and it’s a somewhat unified measure. The cons are pretty clear because these models favor you seeing many patients and billing a lot, and often this favors employers over physicians.

Dr. Patel is a clinical instructor, department of pediatrics, at Columbia University, New York, and a pediatric hospitalist at Morgan Stanley Children’s Hospital of New York–Presbyterian. He reported a conflict of interest with Medumo.
