We report 4 cases of osteitis with extensive necrosis of the maxillofacial bone due to actinomycosis. Histological study showed soft tissue necrosis with bone involvement, suppuration and granulomatous inflammation. At contact with bone destruction, numerous Gram and PAS positive bacteria with branched filaments, inconsistently associated with granules, were noted. Cultures were negative. Ultrastructural study showed in two cases, some elongated bacteria, variable in size, less to one micron in diameter, associated with ossein destruction. Actinomycetes usually represented in the normal oral flora, may become pathogenic in debilited host. Histologic study is necessary for the diagnosis allowing to confirm the tissue invasion by the bacteria.

Introduction: Assessing gender disparity in surgical trainees' operative opportunities and experience quantifies implicit gender bias and reflects a summation of many smaller biased interactions within the operating room environment. Highlighting gender disparity in surgery informs a platform for advocacy.
Methods: A systematic literature search was performed using Medline, Web of Science, OpenMD and Science Direct consistent with the Preferred Reporting Items for Systematic Reviews and Metanalysis guidelines.

Objective: Authors characterized all published adult cases of cutaneous, intertriginous Langerhans cell histiocytosis (LCH) to bring this clinical presentation to the attention of clinicians. We emphasize the morphology, histopathology, immunohistochemical profiles, and genetic mutations associated with these cases.
Materials And Methods: A systematic review of the National Center for Biotechnology Information's PubMed was conducted, utilizing the following specific key words to identify all adult LCH patients with cutaneous intertriginous involvement: "Intertriginous Langerhans," "Vulvar Langerhans," "Genital Langerhans," "Perineal Langerhans," "Perianal Langerhans," "Intergluteal Langerhans," "Inguinal Langerhans," "Axillary Langerhans," and "Inframammary Langerhans.

Purpose: To identify optical coherence tomography (OCT)-based imaging biomarkers that can localize focal leakage points without fluorescein angiography in central serous chorioretinopathy (CSC).
Methods: This retrospective case-control study analyzed 119 consecutive patients (123 eyes) with CSC between April 2018 and February 2024, comprising 66 eyes with focal-leakage type and 57 eyes with diffuse-leakage type. We assessed leakage sites using OCT, and the proportions of OCT findings were compared between focal- and diffuse-leakage types.

Hourglass fascicular constrictions have been reported in fewer than 100 cases globally and only in the upper limb. The etiology remains unknown. Patients often present with self-limiting pain in the affected limb followed by flaccid paralysis.
