RESUMO
In the current mpox outbreak, infections are usually self-limited. We describe 3 patients with uncontrolled HIV and mpox infections lasting months, causing debilitating lesions, complications, and death, despite initiating anti-mpox and antiretroviral therapy. Delayed treatment of mpox with antiviral agents may contribute to poor outcomes in severely immunocompromised patients.

BACKGROUND: Latin American patients in the United States experience significant health disparities. Community health workers (promotoras de salud) reduce disparities by providing culturally appropriate education. While educational interventions have been studied in atopic dermatitis (AD), a chronic dermatologic condition affecting children, none have evaluated the use of promotoras in Spanish-speaking pediatric patients in the United States. OBJECTIVE: To create and evaluate a promotora-led education program for Spanish-speaking caregivers of Latin American, pediatric patients with AD through a randomized, controlled, evaluator-blinded study. METHODS: Children with moderate/severe AD (n = 48) were recruited from the pediatric dermatology clinic at Children's Healthâ in Dallas, TX and randomized to receive clinic education (n = 26) or clinic education plus promotora home visits (n = 22). The primary outcome was overall adherence to topical emollients over the 12-week study, quantified by MEMSCap™ devices; several secondary endpoints were evaluated. RESULTS: Intention-to-treat analysis revealed a trend toward increased overall adherence to emollients over the 12-week study period in promotora (median [interquartile range, IQR]: 43% [26%-61%]) versus non-promotora (median [IQR]: 20% [11%-49%]) (p = .09) groups. SCORAD, AD knowledge, and Spanish-language Parental Quality of Life Questionnaire for AD (Sp-PIQoL-AD) improved in both groups, although there was no statistically significant difference between groups. There was a trend toward increased AD knowledge at Week 4 (p = .06) in the promotora group. CONCLUSIONS: A promotora-led educational intervention is a promising approach in increasing caregiver medication adherence in pediatric, Latin American patients with AD in the United States. Further research using creative and culturally appropriate strategies to increase medication adherence is necessary to reduce health disparities in other racial and ethnic minority populations in the United States.

PURPOSE: To determine the rate of positivity of immunofluorescence studies in buccal biopsies in patients with cicatrizing conjunctivitis undergoing workup for ocular mucous membrane pemphigoid (MMP)/ocular cicatricial pemphigoid (OCP). DESIGN: Retrospective cohort review. PARTICIPANTS: Forty-one patients with cicatrizing conjunctivitis undergoing workup for OCP. METHODS: A retrospective chart review of direct immunofluorescence (DIF) studies in buccal mucosal biopsies was performed. MAIN OUTCOME MEASURES: The primary outcome measure was the rate of positivity of direct and indirect immunofluorescence studies on buccal mucosal biopsies. RESULTS: Twenty-two patients (54%) had a positive buccal mucosal biopsy; 64% of patients (14/22) demonstrated +DIF on initial biopsy and an additional 36% of patients (8/22) on the second biopsy. Eighteen patients underwent conjunctival biopsy. In the 6 patients with a negative conjunctival biopsy, 4 (67%) had a positive buccal biopsy. CONCLUSIONS: Buccal mucosal immunofluorescence studies may be positive in patients with OCP even in the absence of extraocular disease. Buccal mucosal biopsy may be considered as an alternative to or attempted before conjunctival biopsy for the diagnosis of OCP, particularly in patients in whom conjunctival biopsy may be difficult or imminently visually threatening.

INTRODUCTION: Community health workers (CHWs), or promotora de salud, have an important role in healthcare education and advocacy in the Latin American community. We aimed to determine the impact of a promotora de salud program on attitudes and beliefs regarding AD management among Latin American caregivers of pediatric patients with atopic dermatitis. METHODS: This is a sub-study of an ongoing randomized, investigator-blinded, placebo-controlled trial. Mann-Whitney U tests compared questionnaire responses in the standard education group to the promotora group. RESULTS: Caregivers in the promotora group were more likely to state that they knew how to apply wet wraps and use bleach (sodium hypochlorite) baths at 1 month (wet wraps p = .027, bleach baths p = .005) and 3 months (wet wraps p = .005, bleach baths p < .001) demonstrating greater self-efficacy, defined as an individual's belief in their capacity to execute a certain behavior to achieve a desired outcome, compared with the standard education group. CONCLUSIONS: Culturally competent and language concordant educational interventions may improve confidence in utilizing wet wraps and bleach baths among Latin-American caregivers of children with atopic dermatitis, which may improve AD outcomes in the Latin-American community.

We present a severe case of acute generalized exanthematous pustulosis (AGEP) secondary to trimethoprim-sulfamethoxazole complicated by non-infectious circulatory shock in a 16-year-old boy. Hemodynamic instability has been reported as a complication of AGEP in adults, but is rarely observed in pediatric patients. The patient we present demonstrated characteristic cutaneous findings of AGEP including isolated non-follicular, sterile pustules on a background of erythema with involvement at intertriginous areas and subsequently developed non-infectious circulatory shock. This case expands the spectrum of possible clinical presentations for AGEP in pediatric patients.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening conditions with high morbidity and mortality. Supportive care management of SJS/TEN is highly variable. A systematic review of the literature was performed by dermatologists, ophthalmologists, intensivists, and gynecologists with expertise in SJS/TEN to generate statements for supportive care guideline development. Members of the Society of Dermatology Hospitalists with expertise in SJS/TEN were invited to participate in a modified, online Delphi-consensus. Participants were administered 9-point Likert scale questionnaires regarding 135 statements. The RAND/UCLA Appropriateness Method was used to evaluate and select proposed statements for guideline inclusion; statements with median ratings of 6.5 to 9 and a disagreement index of ≤1 were included in the guideline. For the final round, the guidelines were appraised by all of the participants. Included are an evidence-based discussion and recommendations for hospital setting and care team, wound care, ocular care, oral care, urogenital care, pain management, infection surveillance, fluid and electrolyte management, nutrition and stress ulcer prophylaxis, airway management, and anticoagulation in adult patients with SJS/TEN.

Severe group A streptococcus (GAS) infections, particularly necrotizing soft tissue infections (NSTIs), have been associated with the development of streptococcal toxic-shock syndrome (STSS), a systemic illness caused by GAS-derived toxins. Traditional physical examination findings in NSTIs include skin necrosis, crepitus, and hemorrhagic bullae. However, these findings are limited in sensitivity and additional clinical markers may aid in making an early diagnosis of NSTI. We present a case of a superficial infection, specifically GAS necrotizing cellulitis, complicated by STSS in a healthy boy with an associated skin finding of retiform purpura that aided in early diagnosis of a NSTI.

In addition to aiding the diagnosis of viral, bacterial, and fungal diseases, mineral oil preparation, Tzanck smear, and other techniques can be used to diagnose parasitic infections, neonatal pustular dermatoses, blistering diseases, Stevens-Johnson syndrome, and a plethora of other benign and malignant conditions, including granulomatous diseases and tumors. In many cases, these techniques are specific, reliable, and easy to perform and interpret. In others, a certain amount of training and expertise are required. In the proper clinical scenario, these tests are rapid, economical, and compare favorably with other diagnostic methods.

Viral, bacterial, and fungal infections are frequently encountered in clinical practice, resulting in numerous cutaneous manifestations. Although diagnosis of these infections has changed over time because of technological advancements, such as polymerase chain reaction, bedside diagnostic techniques still play an important role in diagnosis and management, enabling rapid and low-cost diagnosis and implementation of appropriate therapies. This 2-part article will review both common and infrequent uses of bedside diagnostic techniques that dermatologists can incorporate into daily practice. This article examines the utility of bedside tests for the diagnosis of viral, bacterial, and fungal infections. The second article in this series reviews the use of bedside diagnostics for parasitic and noninfectious disorders.

BACKGROUND: Recently, isolated reports of pyoderma gangrenosum (PG) secondary to levamisole-contaminated cocaine have been described, with similar serologic findings to the vasculopathic presentation. OBJECTIVE: We sought to describe clinical, histopathological, and serologic findings in 8 patients with PG associated with levamisole-contaminated cocaine. METHODS: Eight consecutive patients presenting with this disease spanning the period from 2011 to 2015 were included for the cohort. Observed variables included: lesion distribution, morphology, serologic titers, and histopathologic evaluation for vasculitis and vasculopathy. RESULTS: All patients reported cocaine exposure prior to the onset of lesions resembling PG. Lesions appeared primarily on the upper (6 of 8 patients) and lower (all 8 patients) extremities. Most patients demonstrated elevated titers for p-ANCA and antiphospholipid antibodies, and a diffuse dermal infiltrate dominated by neutrophils was seen in all biopsy specimens. Lesions improved or remained stable with conservative management or short courses of steroids, and recurrence was only noted on re-exposure to adulterated cocaine. LIMITATIONS: The study is limited by sample size. CONCLUSIONS: PG may occur after exposure to levamisole-adulterated cocaine. Clinical and histopathological findings resemble those seen in conventional forms of PG, whereas serologic findings mirror those seen in other levamisole-associated vasculopathic or vasculitic eruptions. Cocaine avoidance represents a cornerstone of management in these patients.

Importance: Trimethoprim-sulfamethoxazole (TMP-SMX) hypersensitivity reaction, ranging from circulatory shock to aseptic meningitis and respiratory failure, is a potentially life-threatening condition with dermatologic relevance. Objective: To describe the mucocutaneous findings and clinical features of TMP-SMX hypersensitivity reaction. Design, Setting, and Participants: This was a retrospective case series study of 7 patients who developed a characteristic rash, hemodynamic changes, and end-organ dysfunction after treatment with TMP-SMX at a large university hospital system during January 2013 to March 2022. Exposures: Treatment with TMP-SMX within 2 weeks of the reaction. Main Outcome and Measures: Descriptions of the condition, including the demographic information of the affected population, the reaction timeline, and mucocutaneous and clinical features. Results: The cohort comprised 7 patients (median [range] age, 20 [15-66] years; 4 female and 3 male). The most common mucocutaneous findings were generalized sunburn-like erythema without scale, conjunctivitis, and mild facial and acral edema. Three patients had previous exposure to TMP-SMX and developed symptoms in 1 day or less, while those without prior exposure presented from 4 to 11 days after drug initiation. Among the 7 patients, 6 had fever, 7 had hypotension, and 7 had tachycardia. All patients had lymphopenia and evidence of end-organ dysfunction with either kidney or liver involvement. Median (range) time to resolution was 72 (48-96) hours. Conclusions and Relevance: This retrospective case series indicates that SCoRCH (sudden conjunctivitis, lymphopenia, and rash combined with hemodynamic changes) should be considered in the differential diagnosis of patients presenting with acute generalized sunburn-like erythema, conjunctivitis, systemic symptoms, and hemodynamic changes in the setting of recent TMP-SMX use.
