- Research shows medical students lack training on skin conditions for people of color, which negatively impacts healthcare outcomes.
- To address this, a one-hour virtual lecture was created to teach common skin diseases across all skin types, particularly those relevant for licensing exams.
- Results from a questionnaire indicated significant improvement in recognizing conditions like rosacea, psoriasis, and basal cell carcinoma in skin of color after the module, suggesting that targeted education can enhance diagnostic skills.
Article Synopsis
- Keratinocyte carcinoma (KC) is the most common type of skin cancer, but its effects on survival aren't well understood.
- This study looked at how two types of KC, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), affect survival in people from Iceland.
- The results showed that BCC usually doesn't affect survival much, but SCC can be more dangerous, especially for younger people under 50.
This study investigated the outcomes and follow-up behaviors of participants from two free skin cancer screening events in the United States. This survey, with 296 participants and a 31% response rate, gathered information on participant demographics, personal history of skin cancer, knowledge of skin screening practices, and follow-up behaviors. There was a high follow-up rate of 92.

View Article and Find Full Text PDFBackground: Patients with alopecia areata (AA) may access a wide range of sources for information about AA, including the recently developed ChatGPT. Assessing the quality of health information provided by these sources is crucial, as patients are utilizing them in increasing numbers.
Objectives: The aim of the study was to evaluate appropriateness and accuracy of responses to common patient questions about AA generated by ChatGPT.
Background: A growing body of evidence suggests that several inflammatory skin diseases (ISDs) are associated with systemic inflammation and cardiovascular disease (CVDs).
Methods: We used the TriNetX analytics platform to conduct a retrospective, cross-sectional, single-center study in the Mount Sinai Health System network. Cases (all patients ≥18 years of age with a diagnosis of 1 of the 4 ISDs studied) were compared with matched controls (no history of any of these ISDs) to evaluate odds ratios for being diagnosed with CVD.
Article Synopsis
- Policymakers are reassessing temporary telehealth policies from the COVID-19 era, which will affect future teledermatology use.* -
- Key changes included payment parity, relaxed site and licensure requirements, but waivers will end after 151 days post-public health emergency, and asynchronous telehealth remains unreimbursed.* -
- Dermatologists need to keep updated on policy changes, provide evidence of teledermatology's value, and advocate for long-term accessibility for patients.*
Diphencyprone (DPCP), a topical contact sensitizer, has shown efficacy in treating cutaneous melanoma metastases, including at times beyond the directly treated sites, but biomarkers indicative of treatment response have not been characterized. Thus, we performed a proteomic analysis of the skin and serum of five patients with cutaneous melanoma metastases treated with DPCP on days 0, 63, and 112 of the treatment course. In the serum, we found a significant upregulation ( < 0.

Topical immunomodulators such as diphencyprone (DPCP) also have clinical use in advanced melanoma, particularly in the treatment of cutaneous metastases. In a previous report, we characterized the enhanced clinical response to dual agent immunotherapy with pembrolizumab and DPCP in a patient with cutaneous melanoma metastases.

Acute radiation dermatitis (RD) is one of the most common adverse effects of RT and may lead to secondary infection, disfigurement, and discontinuation of therapy. The authors report the efficacy of a multidisciplinary collaboration between radiation oncology, dermatology, and wound care teams in the management of severe, acute RD.

- Erythropoietic protoporphyria and X-linked protoporphyria are rare genetic skin disorders that are often misdiagnosed due to lack of physician knowledge.
- The text presents evidence-based consensus guidelines created by expert committees to improve diagnosis, monitoring, and management strategies for these conditions.
- Key elements of the guidelines include appropriate testing, symptom prevention, management of complications, and ongoing monitoring for related health issues, emphasizing the need for early diagnosis to take advantage of new therapies.
Background: Despite increasing cross-collaboration between providers who perform cutaneous surgery, a disparity still exists in the current practices regarding perioperative management. This could lead to treatment delays, patient confusion, and increased morbidity, such as clotting, infection, and discomfort of patients.
Objective: To characterize the management practices of different providers in regards to perioperative anticoagulation and antiplatelet therapy for cutaneous surgery.
