Introduction: Fixed pigmented erythema (FPE) is a common toxidermia characterized by the appearance of one or more annular, erythematous and hyperpigmented spots, following the systemic administration of a drug. The main aim of this study was to describe the epidemiological and clinical aspects of fixed pigmented erythema at the Departmental University Hospital Center Borgou/Alibori (DUHC-B/A) from 2009 to 2022. Methods: This was a descriptive cross-sectional study with retrospective data collection, based on the records of patients seen in the Dermatology-Venerology Unit for FPE. Initially, all files bearing the diagnosis of toxidermia were identified; then, those with the diagnosis of FPE with usable data were retained. Data were entered using EpiData 3.1 and analyzed using EpiData Analysis. Results: Sixty-four patients were enrolled during the study period. The prevalence of FPE was 0.73%, with a male predominance. The most common drug identified was cotrimoxazole, followed by paracetamol and quinine. Over half of the patients (52.9%) were self-medicating. Conclusion: Although FPE occurs rarely, it remains the most frequent toxidermia at the DUHC-B/A. It can be severe in its generalized bullous form. Avoiding the practice of self-medication could help reduce its prevalence....
Background/Objectives: The rising incidence of skin cancer places a significant burden on Australia's health workforce. To support workforce planning, we estimated the supply of dermatologists and general practitioners (GP) working in skin cancer medicine, service demand and need across Queensland in 2023. Methods: We built a supply- , demand- and needs- based health workforce model using publicly available data. We collated data on the numbers of clinicians and clinical full- time equivalents (FTE), Medicare- reported skin cancer services and melanoma incidence. We quantified health workforce supply and clinical workload, clinical FTE per 100,000 population, number of Medicare claims for skin cancer services per clinical FTE and incident cases of melanoma per clinical FTE for all of Queensland and across 19 Level 4 Statistical Areas. Results: Queensland had 7179 GPs (852 adjusted FTE) and 124 (71 adjusted FTE) dermatologists servicing 5,527,369 residents, with an estimated 17 FTE skin cancer clinicians per 100,000 population. Ten (53%) SA4 areas had no dermatologists, with none residing in central or western Queensland. Seven of the nine SA4 levels with dermatologists were in southeast Queensland (78%), and 47% of all FTE dermatologists practised in Brisbane Inner City. GPs were well distributed relative to population size. Conclusions: Access to dermatology services is limited for Queensland residents living outside the southeast region, with few providers available within reasonable proximity. GPs are managing a growing skin cancer workload in Queensland. This could be eased by increased use of telemedicine, upskilling other health professionals in skin cancer medicine and improving care efficiency....
Background: Cutaneous wounds are common in outpatient care, but national patterns of who manages them and how antimicrobials are used remain unclear. Objectives: To characterize outpatient specialty involvement and antimicrobial use for acute and chronic cutaneous wound visits in the United States. Methods: We conducted a retrospective cross-sectional analysis of 2011–2019 National Ambulatory Medical Care Survey (NAMCS) data. Cutaneous wound visits were identified using prespecified ICD-9-CM and ICD- 10-CM codes and classified as acute (open or traumatic wounds and burns) or chronic (pressure injuries and lower-limb ulcers). Survey weights were applied to estimate national visit volumes, specialty shares, and antimicrobial utilization patterns. Results: We identified 45.1 million cutaneous wound visits, representing 0.8% of all outpatient visits, of which about two thirds were acute and one third chronic. Primary care physicians accounted for the largest share of wound visits, while dermatologists managed 3.9% of overall wound visits, 2.4% of acute visits, and 7.4% of chronic visits. Among 156.6 million medications recorded at wound visits, antimicrobials represented 13.1% overall, 14.9% in acute visits, and 10.2% in chronic visits. Cephalexin accounted for 32.1% of antimicrobial medications overall and 39.2% in acute visits, whereas chronic wound visits had a more heterogeneous antimicrobial profile that included topical mupirocin, cephalexin, trimethoprim–sulfamethoxazole, and topical nystatin. Conclusions: Outpatient cutaneous wound care in the United States is delivered predominantly by primary care clinicians and relies heavily on a small set of systemic and topical antimicrobials, highlighting opportunities to strengthen antimicrobial stewardship and expand dermatology’s role in chronic wound management....
Background: Large language models (LLMs) have shown considerable promise in supporting clinical decision‐making. However, their adoption and evaluation in dermatology remains limited. This study aimed to explore the preferences of Chinese dermatologists regarding LLM‐generated responses in clinical psoriasis scenarios and to assess how they prioritize key quality dimensions, including accuracy, traceability, and logicality. Methods: A cross‐sectional, web‐based survey was conducted between December 25, 2024, and January 22, 2025, following the Checklist for Reporting Results of Internet E‐Surveys guidelines. A total of 1247 valid responses were collected from practicing dermatologists across 33 of China's provincial‐level administrative divisions. Participants evaluated responses to five categories of clinical questions (etiology, clinical presentation, differential diagnosis, treatment, and case study) generated by five LLMs: ChatGPT‐4o, Kimi.ai, Doubao, ZuoYiGPT, and Lingyi‐agent. Statistical associations between participant characteristics and model preferences were examined using chi‐square tests. Results: ChatGPT‐4o (Model 1) emerged as the most preferred model across all clinical tasks, consistently receiving the highest number of votes in case study (n = 740), clinical presentation (n = 666), differential diagnosis (n = 707), etiology (n = 602), and treatment (n = 656). Significant variation in model preference by professional title was observed only for the differential diagnosis task ( χ2 = 21.13, df = 12, p = 0.0485), while no significant differences were found across hospital tiers (p > 0.05). In terms of evaluation dimensions, accuracy was most frequently rated as “very important” (n = 635). A significant association existed between hospital tier and the most valued dimension ( χ2 = 27.667, df = 9, p = 0.0011), with dermatologists in primary hospitals prioritizing traceability more than their peers in higher‐tier hospitals. No significant associations were found across professional titles (p = 0.127). Conclusions: Chinese dermatologists suggest a strong preference for ChatGPT‐4o over domestic LLMs in psoriasis‐related clinical tasks. While accuracy remains the primary criterion, traceability and logicality are also critical, particularly for clinicians in lower‐tier hospitals. These findings suggest that future clinical LLMs should prioritize not only content accuracy but also source transparency and structural clarity to meet the diverse needs of different clinical settings....
Background: Primary cutaneous B-cell lymphomas (CBCLs) are a rare and heterogeneous group of lymphomas, among which the anaplastic variant of diffuse large B-cell lymphoma (A-DLBCL) represents an exceptionally rare entity. Although they typically present as painless and non-ulcerated skin lesions, rare variants may exhibit atypical clinical features. Pyoderma gangrenosum (PG) is a rare inflammatory ulcerative disease that may overlap clinically with other ulcerative dermatoses and pose diagnostic challenges due to the absence of standardized differential algorithms. Methods: An 85-year-old male presented with multiple rapidly progressive, painful, ulcerative lesions, initially misdiagnosed as PG and treated with oral cyclosporine with no clinical response. Skin biopsy specimens underwent detailed histopathological and immunohistochemical evaluation. Results: The analyses revealed dense infiltration of atypical large lymphoid cells, with CD20, CD45, and CD30 positivity, and a Ki-67 proliferation index of approximately 90%, consistent with primary cutaneous A-DLBCL. Owing to the delayed correct diagnosis, the patient’s condition deteriorated rapidly, leading to his death before appropriate therapy could be initiated. Conclusions: The case documents an exceptionally rare cutaneous presentation of A-DLBCL, expanding the extremely limited literature on this enigmatic entity. Furthermore, it underscores the fundamental role of early skin biopsy in the differential diagnosis of non-specific ulcerative lesions, which is critical for ensuring appropriate treatment administration within the therapeutic window in cases of malignancy....
Background: Dermatologic conditions are a significant reason for pediatric hospitalizations in the United States. A prior analysis of the 2012 Kids' Inpatient Database (KID) established a national benchmark for this burden, but changes in medical coding, healthcare delivery, and demographics necessitate an updated assessment. This study aimed to quantify the current inpatient burden of pediatric dermatology and to identify associated demographic risk factors, financial costs, and mortality using a recent, nationally representative database. Methods: A cross- sectional study was conducted using the 2022 KID. Pediatric hospitalizations with a primary dermatology diagnosis (ICD- 10- CM) were identified. Survey weights were used to generate national estimates of admission counts, costs, and mortality. Multivariable logistic regression was used to identify independent risk factors for a primary dermatology hospitalization. Results: In 2022, there were an estimated 29,766 pediatric dermatology hospitalizations, representing 2.3% of all pediatric admissions and a decline from 4.2% in 2012. These admissions generated a total national cost of $449.3 million. After adjusting for covariates, factors associated with higher odds of a dermatology admission included age 2–5 years (OR: 1.35; 95% CI: 1.21–1.52), Asian/Pacific Islander race (OR: 1.49; 95% CI: 1.32–1.69), Native American race (OR: 1.17; 95% CI: 1.00–1.36), Hispanic ethnicity (OR: 1.07; 95% CI: 1.01–1.14), lowest income quartile (OR: 1.06; 95% CI: 1.01–1.12), and Medicaid coverage (OR: 1.09; 95% CI: 1.04–1.14). Female sex was associated with lower odds (OR: 0.95; 95% CI: 0.92–0.98). In- hospital mortality was 0.1%. Conclusion: The national burden of inpatient pediatric dermatology has decreased over the past decade. However, significant disparities related to socioeconomic status and race/ethnicity persist and have evolved. These findings underscore the continued need for interventions aimed at improving access to outpatient dermatologic care for underserved pediatric populations....
