Cost effectiveness of melanoma in situ resection and repair by dermatology compared to non-dermatology specialties at a single institution.

Melanoma-in-situ (MIS) is treated with surgical resection by many specialties. Dermatologists perform these procedures in outpatient settings while others often employ operating rooms and general anesthesia. We hypothesized that MIS managed by dermatology was less costly than that managed by other specialties. All cases of MIS treated at our institution over a 3-year period were evaluated retrospectively for demographic and clinical characteristics and categorized by treating specialty. Estimated cost information was determined using records of charges billed. The mean total cost for MIS treated with wide local excision (WLE) by dermatologists was $1089 (CI = $941-1237) versus all other specialties at $5172 (CI = $2419-7925) (p < 0.001). MIS treated with Mohs micrographic surgery and repaired by dermatology (mean = $2325, CI = $2241-2409) was also less expensive than MIS treated by other specialties with WLE (p < 0.001). The results suggest MIS is significantly less costly to patients and the health care system when treatment is performed by dermatologists compared to other surgical specialties. This is likely due to dermatologists performing the procedures in less expensive outpatient settings.

Sudden Conjunctivitis, Lymphopenia, and Rash Combined With Hemodynamic Changes (SCoRCH) After Trimethoprim-Sulfamethoxazole Use: A Case Series Study of a Hypersensitivity Reaction.

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.

A severe presentation of acute generalized exanthematous pustulosis with non-infectious circulatory shock in an adolescent.

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.
