Article Synopsis
- * The study employed a SEIR model to analyze transmission dynamics and found that MSM with high sexual activity contributed significantly more to mpox spread than those with low sexual activity, but vaccinated individuals were less likely to spread the virus.
- * Findings suggest that ongoing vaccination efforts, increased awareness in at-risk communities, and regular genomic surveillance are essential for managing future mpox outbreaks and potential threats from new viral clades.
Article Synopsis
- Lymphogranuloma venereum (LGV) is a sexually transmitted infection that primarily affects the anogenital area but can occasionally manifest in extragenital locations, like the neck.
- A case study highlights a young man with HIV who experienced painful swelling in his neck, leading to a challenging diagnosis that required various medical tests.
- The patient's diagnosis of LGV was confirmed via genotyping, and he was effectively treated with doxycycline and surgical drainage, underscoring the need for thorough testing in patients with unexplained neck swelling, especially those with a history of unprotected oral sex.
Article Synopsis
- * By sequencing 52% of confirmed cases, researchers uncovered key sublineages of the mpox virus and found evidence of early emergence and spread in Portugal, particularly among men who have sex with men.
- * The findings emphasize the importance of sexual networks and events like saunas in the virus's spread, showcasing genomic epidemiology as a valuable tool for monitoring and controlling mpox outbreaks and informing vaccine strategies.
Cutaneous and systemic plasmacytosis is a rare disorder characterized by cutaneous polyclonal plasma cell infiltration frequently associated with polyclonal hypergammaglobulinemia and lymphadenopathy. We report a case of a 67-year-old woman with an inflammatory ulcerated plaque in the left masseter region. A skin biopsy showed dense perivascular infiltrate of mature plasma cells in the dermis without atypia and immunoglobulin light chain restriction.

When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala.

In the last decade this genus has been reported as the third most common cause of bacteremia. We present the case of a 78-year-old female who was admitted to the emergency room because of nausea, lipothymia, and weakness.
View Article and Find Full Text PDFSeveral variants of dermatofibroma have been described. They are essentially distinguished by their clinical and histopathological features. To review the mainfeaturesof these variants, a retrospective study of skin biopsies and tissue excisions of dermatofibromasperformed in the dermatology and venereology service at the Hospital Garcia de Orta between May 2007 and April 2012 was carried out.
