A Rare Case of Peritoneal Dialysis-Associated Peritonitis with Sphingomonas koreensis.

Sphingomonas species are ubiquitous gram-negative, aerobic bacteria frequently found in aquatic environments such as drinking water and very seldom in hemodialysis fluids or supposedly sterile drug solutions. Human infections with the gram-negative Sphingomonas species are rare and peritonitis with these organisms even rarer. Here we report a case of polymicrobial peritonitis due to Sphingomonas koreensis and Escherichia coli in a patient undergoing peritoneal dialysis (PD).

Pulmonary infections diagnosed by BAL: a 12-year experience in 1066 immunocompromised patients.

Bronchoalveolar lavage (BAL) is a useful tool in the diagnosis of pulmonary infections in immunocompromised patients. We aimed to compare the spectrum of infectious pulmonary complications diagnosed using BAL in a large consecutive cohort of immunocompromised patients. The diagnostic yield of 1066 BAL specimens was analyzed in 4 different groups of immunocompromised patients (HIV; solid organ transplants; high-dose chemotherapy and/or stem cell transplants; other immunosuppressive therapy) suffering from fever, respiratory symptoms and/or infiltrates on chest X-ray.

Sedative drug requirements during flexible bronchoscopy.

Background: There is a paucity of data comparing doses of sedative medication during bronchoscopy in immunosuppressed and non-immunosuppressed patients.

Objectives: The aim of this study was to define the sedative medication doses used in specific patient groups during bronchoscopy.

Methods: Bronchoscopy was performed under local anesthesia, sedation with intermittent boluses of intravenous midazolam and intravenous hydrocodone 5 mg.
