We investigated the relationship between sleep-disordered breathing (SDB) and Cheyne-Stokes respiration (CSR) while awake as well as mortality. Eighty-nine consecutive outpatients (29 females) with congestive heart failure (CHF; left ventricular ejection fraction, LVEF <45%) were prospectively evaluated. The presence of SDB and of CSR while awake before sleep onset was investigated by polysomnography. SDB prevalence was 81 and 56%, using apnea-hypopnea index cutoffs >5 and >15, respectively. CHF etiologies were similar according to the prevalence of SDB and sleep pattern...

A review of the epidemiology of scoliosis reveals that it is costly in human suffering and health care resources. The terminology is defined and classifications explained. The full geometric description of scoliosis includes the three-dimensional description of the vertebral column, as well as the rib cage. Stereoradiographic and stereophotogrammetric (Raster and Moire) techniques are introduced. The coupling in a kinematic sense between, for example, lateral bend and rotation is compared to the orientation coupling in scoliosis...
