Despite evidence to suggest a relationship between time of year and hidradenitis suppurativa (HS) flaring, no studies have been conducted to date to establish a relationship directly between temperature and flaring. In this study, we aim to validate a classification approach based on administrative data for identifying medical encounters that likely represent HS flares in patient with a known diagnosis of HS within the Mass General Brigham Health System (MGB) and examine the relationship between average daily temperatures and HS disease flaring among patients in Boston. This is a retrospective cohort study. Participants were individuals with HS presenting to emergency departments or dermatology outpatient clinics with disease flares between January 2017 and January 2022. The average number of encounters for HS flares was compared with the temperature for that day and the 3- and 7-day periods prior. There were 2567 patient encounters for HS flares included in the study. Of the total identified HS flares, 75.6% occurred in females and 39.1% occurred in patients who identified as Black. Uniformly small but statistically significant relationships were noted between increased temperature and presentations for hidradenitis suppurativa flare with the highest correlation coefficient (0.0768) noted with a 3-day lag time between the heat experienced and day of presentation for flare. Increased temperature is associated with a small, but statistically significant increase in HS disease flaring. As such, HS disease flaring may rise as global temperatures do, suggesting an increase in the global burden of HS as climate change persists., (© 2023.

Ecthyma gangrenosum is an uncommon cutaneous eruption that can initially present with painless macules, which rapidly evolve into necrotic ulcers. This study sought to characterize clinicopathologic features of ecthyma gangrenosum from a single integrated health system. Our cohort consisted of 82 individuals diagnosed with ecthyma gangrenosum. Lesions were most commonly found in the lower extremities (55%) and the truncal region (20%). A wide variety of fungal and bacterial etiologies were found among our cohort. The majority of patients with EG were immunocompromised (79%) and 38% of patients also experienced sepsis. The mortality rate seen in our cohort was approximately 34%. No statistical differences in mortality outcome due to EG related complications were seen between pathogen etiology, and distribution or location of lesions. Patients who were septic or immunocompromised died more frequently than non-septic or immunocompetent patients, suggesting poorer prognosis., (© 2023.

Full body skin exams and self-skin exams are screening methods associated with reduced skin cancer incidence due to earlier detection and treatment of lesions. We performed a retrospective analysis on skin cancer screening and risk factors from the Health Information National Trends Survey (HINTS). The study cohort comprised a weighted population of 478,008,736 respondents, of whom 26,727,370 were patients with disabilities. Respondents with disabilities reported a lower frequency of full body skin exams (OR 0.74; CI 95% 0.69-0.79; P < 0.001) and self-skin exams (OR 0.85; CI 95% 0.78-0.91; P < 0.001), compared to respondents without disabilities. Lower rates of self-guided and clinician-guided screening may adversely affect skin cancer-related morbidity and mortality in persons with disabilities. Future research is needed to identify barriers to self-skin exams and full body skin exams in this population., (© 2023.

A recent mandate by the Centers for Medicare and Medicaid Services (CMS) required hospitals to publish prices online. This study examined the utility of CMS-mandated price estimators for dermatology procedures. Chargemasters and price-estimator tools from the five largest hospitals in each state (n = 250) were reviewed for accessibility. Price estimators were also searched for the presence of dermatologic procedures and their estimated prices. Of the 250 hospitals included, 89.6% of chargemasters and 92.8% of price estimators were accessible. Of the available chargemasters and price estimators, 98.7% and 63.8% contained pricing data on dermatologic procedures, respectively. The most common dermatology procedures listed were debridement of subcutaneous tissue (CPT 11042) with a median price of $1,135.50 (IQR $577-$3533.67; n = 80), followed by simple incision and drainage of skin abscess (CPT 10060) with a median price of $956.00 (IQR $465.50-$6506.00, n = 79), and single punch biopsy of skin (CPT 11104) with a median price of $506.06 (IQR $356.50-$922.08, n = 29). Although price estimator tools are widely available in patient-friendly and searchable formats, they are not optimized for shoppable dermatologic services. Adding more dermatologic procedures to patient-friendly price-estimator tools can help patients directly realize savings from price shopping., (© 2023.
