A 18-year-old female complained of a dyspneic sensation and involuntary movements in the epigastrium. On physical examination, fine rhythmic movements in the epigastrium were observed on each inspiration with a rate of 5-10 per breath. Arterial blood gas analysis was normal. ⋯ In two of them, the spontaneous respiration was superimposed on a high-frequency wave throughout the whole respiratory cycle while in one case the high-frequency wave developed only in the inspiratory phase of spontaneous respiration. In the present case the respiratory flow pattern was similar to the last mentioned and the EMG-analysis of respiratory muscles confirmed that the flutter waves were driven by intercostal muscles and diaphragm. Furthermore, synchronization of activities of the two respiratory muscles suggests that the syndrome is of central origin.

Case Reports[A case of obstructive sleep apnea syndrome remarkably improved by gastric restriction surgery].
A 23-year-man with morbid obesity and obstructive sleep apnea syndrome (OSAS) was admitted. He was 170 cm in height and 170 kg in weight. He underwent dietary treatment several times, but his weight returned to its original level, or even higher, within a short period. ⋯ The postoperative findings revealed a dramatic body weight reduction. At the same time, the results of apnea and oxygen desaturation were remarkably improved too. These results indicate that weight reduction surgery is a definitely effective treatment for morbid obesity associated with OSAS.
