Laboratory versus portable sleep studies: a meta-analysis.

Objective: The objective of this meta-analysis study was to compare the accuracy of home sleep studies with laboratory polysomnography in the diagnosis of obstructive sleep apnea (OSA).

Methods: Eligible studies included prospective cohort studies of portable and in-laboratory sleep studies performed on the same groups of patients. A comparison of respiratory disturbance index (RDI), mean low oxygen saturation levels, sleep time, rate of inadequate studies, and average cost per examination was made between portable and in-laboratory sleep studies.

Orbital volumetric analysis of allergic fungal sinusitis patients with proptosis before and after endoscopic sinus surgery.

Background: The aim of this study was to examine the changes of orbital volumes in allergic fungal sinusitis (AFS) patients with proptosis who undergo endoscopic sinus surgery.

Methods: A retrospective study of operative patients with proptosis due to AFS was performed. Normative data were obtained using patients with chronic sinusitis without orbital involvement.
