Adaptive servoventilation for treatment of sleep-disordered breathing in heart failure: a systematic review and meta-analysis.

Background: Adaptive servoventilation (ASV) has demonstrated efficacy in treating sleep-disordered breathing (SDB) in patients with heart failure (HF), but large randomized trials are lacking. We, therefore, sought to perform a systematic review and meta-analysis of existing data.

Methods: A systematic search of the PubMed database was undertaken in March 2012.

A limited form of Churg-Strauss syndrome presenting without asthma and eosinophilia.

We report a young woman presenting with digital gangrene, paranasal sinusitis, mononeuritis multiplex, and rapidly progressive glomerulonephritis without asthma and eosinophilia - an extremely rare variant of this disease.
