ologists, and at least three subspecialty surgeons, so attesting to the interdisciplinary nature of sleep apnea syndromes. Sleep apnea syndromes are of two types, the so-called central apneas and those arising from partial or complete obstruction in the upper airway. This volume focusses heavily on the latter variety and clearly indicates the diagnostic requirements and the multiple functional and anatomic causes for this disease. The assessment of sleep derangements, the techniques of polysomnography, the physiology of the disorder, and specific technical requirements of both tracheostomy and diaphragm pacing are presented by a series of authorities. The book is well produced, clearly illustrated, and is strongly recommended for workers in the field and for those who wish to understand the relation between sleep, breathing, cardiac, cerebral, hormonal, and psycho-social functions in their patients. This book should result in an awareness of these diseases, and is essential for general internists since the manifestations of the syndromes include cardiac arrhythmias, obesity, cardiorespiratory failure, and neuropsychiatric dysfunction.
