Human infection due to Bacillus pumilus is exceptional. We report 3 cases of cutaneous infection caused by B. pumilus that occurred in 3 shepherds, 2 of whom were members of the same family. The lesions appeared to have a morphology similar to that of cutaneous anthrax lesions. Two patients were cured after treatment with amoxicillin-clavulanate, and the third patient was cured after prolonged treatment with ciprofloxacin. To our knowledge, primary cutaneous infection due to B. pumilus has not been reported. B. pumilus should be considered in patients who develop lesions suggestive of cutaneous anthrax.

Background: While invasive fusariosis and lomentosporiosis are known to be associated with fungemia, overall data on mold-related fungemia are limited, hampering early management. This study aimed to describe the epidemiology of mold-positive blood cultures.
Methods: Epidemiological and clinical data on mold-positive blood cultures from 2012 to 2022 were obtained from the RESSIF database.

Objectives: The purpose of this study was to determine reference points for thermal perception in cutaneous lesions of leprosy, a disease caused by Mycobacterium leprae characterised by hypoesthesia in skin lesions due to nerve and Schwann cell infection. Early diagnosis is essential to control transmission and effectively treat the disease.
Methods: Quantitative thermal testing (QTT) has been proposed as a valuable tool for early detection of the disease, initiation of treatment, and monitoring of nerve damage.

Inpatient consultative dermatologists play a critical role in the care of hospitalized patients with skin disease. Our review of the 2023-2024 dermatology literature identified several areas of active investigation relevant to inpatient dermatology. In this article, we highlight advances in the understanding of severe cutaneous adverse drug reactions, diagnosis and prevention of skin and soft tissue infections, and management of autoimmune blistering diseases (AIBDs).

Hookworm infection represents a major global disease burden, in terms of both morbidity and economic impact, and there has been a resurgence of hookworms in developed nations where these parasites were once thought to be eradicated. Hookworms can infest humans or other mammals as their primary hosts depending on the species. The 2 most common species that seek human hosts-Necator americanus and Ancylostoma duodenale-enter the body through the epidermis, and hookworm infection may manifest as a pruritic and papular inflammatory reaction know as ground itch.
