Association between Obstructive Sleep Apnea and Acute Kidney Injury in Critically Ill Patients: A Propensity-Matched Study.

Background/aims: Obstructive sleep apnea (OSA) is a known risk factor for chronic kidney disease (CKD); however, its association with acute kidney injury (AKI) is not well documented. We aimed to study whether OSA is associated with the risk of AKI in the intensive care unit (ICU) setting.

Methods: All consecutive adult Olmsted County, MN residents who were admitted in Mayo Clinic ICUs from January 1, 2010 to December 31, 2010 were screened.

Lesson of the month 1: Lobar pulmonary consolidation in an immunocompromised host.

A 19-year-old male with a history of idiopathic panuveitis, currently taking methotrexate and infliximab, presented to our institution with 6 weeks of cough, dyspnoea and fevers. He had failed outpatient antimicrobial therapy. Computerised tomography (CT) of the chest revealed the presence of a lobar pneumonia and he was treated with broad spectrum antibiotics, which did not improve his symptoms.
