A capricious case of thoracic osteomyelitis.

() is a gram positive, coagulase-negative (CoNS) that occurs as a commensal pathogen on the human skin. It recently has been recognized in causing nosocomial infections involving the bloodstream, urinary tract, heart, bone, and joints, particularly in immunosuppressed patients or individuals with prosthetic devices. Previously, was underreported as it was difficult to identify in the clinical microbiology laboratory; however, due to advances in molecular identification methods and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), more clinical cases are being identified in human isolates and appropriately treated.

A Case of Infective Endocarditis Caused by : Unraveling a Rare Pathogen and Dire Outcome.

(formerly classified as ) is a gram-negative bacillus (GNB) that occurs as an opportunistic pathogen in neonates and immunocompromised patients. species have been implicated in nosocomial settings leading to infections involving the urinary tract, respiratory tract, liver, biliary tract, meninges, and even in rarer conditions-blood stream infection and infective endocarditis (IE). Gram-negative bacilli are responsible for 3% to 4% of all IE cases and have been traditionally associated with intravenous drug users.

Disseminated nocardia cyriacigeorgica presenting as right lung abscess and skin nodule.

Nocardia species are ubiquitous in the environment and can be found worldwide. Direct inhalation remains the most commonly attributed route of infection with Nocardia asteroides complex, causing 50% of invasive infections. Improved molecular methods have identified a significant proportion of N.

Comparison of short-course (5 days) and standard (10 days) treatment for uncomplicated cellulitis.

Background: Cellulitis is a condition routinely encountered in the primary care setting. No previous study has compared a short (5 days) vs standard (10 days) course of therapy of the same antibiotic in patients with uncomplicated cellulitis.

Methods: We performed a randomized, double-blind, placebo-controlled trial to determine if 5 days of therapy has equal efficacy to 10 days of therapy for patients with cellulitis.

Esophageal ulceration due to cytomegalovirus infection in a patient with acute retroviral syndrome.

Opportunistic infections during primary infection with human immunodeficiency virus type 1 have occasionally been reported in the medical literature, and those caused by cytomegalovirus have tended to be severe and prolonged. We describe a 40-year-old man who had acute retroviral syndrome complicated by a severe cytomegalovirus-induced esophageal ulceration, which was successfully treated with total parenteral nutrition and ganciclovir in addition to highly active antiretroviral therapy.
