Diagnosis and Management of Bullous Disease.

Bullous diseases are a group of dermatoses primarily characterized by the presence of vesicles (0.1-0.9 cm) or bullae (>1 cm). There are various categories of bullous disease: allergic, autoimmune, infectious, mechanical, and metabolic. These diseases affect individuals in all decades of life, but older adults, age 65 and older, are particularly susceptible to bullous diseases of all etiologies. The incidence of these disorders is expected to increase given the advancing age of the general population. In this comprehensive review, we will outline the common bullous diseases affecting older individuals and provide an approach to evaluation and management.

Eruptive Papules as a Cutaneous Manifestation of Metastatic Prostate Adenocarcinoma.

ABSTRACT: Cutaneous metastasis from prostate cancer is a rare manifestation, occurring in less than 1% of all cases of prostate cancer. Prostate cancer metastasis occurs most often in lymph nodes and bones. In this study, we present the case of a 55-year-old man with prostate adenocarcinoma and progressive papules on his left chest that developed shortly after androgen deprivation therapy was initiated. This case emphasizes the significance of considering cutaneous metastasis in the diagnostic differential when assessing patients with a history of cancer and the need to thoroughly evaluate these cases.

Minority hair tax: pricing bias in haircare products.

Background: Black haircare is an estimated $2.51-billion-dollar industry. Black women spend 9 times more on ethnic hair products than non-Black consumers. The haircare industry has adapted to these market trends by developing products catering to the needs of "natural hair," referring to curly to tightly coiled hair texture that has not been chemically straightened with a relaxer. Anecdotally, natural haircare products are relatively expensive. Objective: We aimed to investigate texture-based price differences for haircare products targeting coily/curly compared to straight hair types. Methods: Data were collected in August 2022 from 6 brands available on www.amazon.com. After stratifying the data by manufacturer, hair texture, and average price/oz, we used 2 sample t-test with equal variances to examine cost differences. Results: Overall, there was a significant difference in average price/oz between all coily/curly and straight hair products, with coily/curly hair products being more expensive. When stratified by manufacturer, one leading US manufacturer sold coily/curly hair products at a higher price ($0.66/oz ±$0.05) compared with straight hair products ($0.46/oz ±$0.04), t14 = 2.8967, P < 0.0134. Limitations: A small sample size of only shampoos and conditioners were analyzed, which may not represent the number of haircare products that consumers use. Conclusion: Pricing policies should ensure that all individuals have access to effective, affordable haircare products. Dermatologists should also be cognizant of pricing differences to direct patients with natural hair to fairly priced products.
