Mpox (Monkeypox) On Board a Naval Warship.

We report a case of mpox in an active duty male on board a naval warship, who presented with a chancre-like penile lesion and ulcerating lymphadenopathy in the setting of a nonreactive treponemal test. Despite empirical therapy for sexually transmitted infections, he developed a fever and a generalized pustular rash. The patient was placed in isolation, and contact tracing was performed.

A sex-based analysis of complete blood count features during acute, untreated Lyme disease.

Introduction: Although lymphopenia has been described in acute Lyme disease (LD), the complete blood count (CBC) has not been comprehensively examined, nor have sex-based analyses been conducted. We analyzed CBC values and identified sex-based trends among patients with early LD by comparing both to controls without a history of LD and to patients' pre-morbid values.

Methods: We enrolled participants from the Mid-Atlantic US with diagnostic erythema migrans and controls with no history of LD.

Randomized Multicenter Trial for the Validation of an Easy-to-Administer Algorithm to Define Penicillin Allergy Status in Sexually Transmitted Infection Clinic Outpatients.

Background: Approximately 15% of patients in sexually transmitted infection (STI) clinics report penicillin allergies, complicating treatment for syphilis and gonorrhea. Nonetheless, >90% do not have a penicillin allergy when evaluated. We developed and validated an algorithm to define which patients reporting penicillin allergy can be safely treated at STI clinics with these drugs.
