The effect of environmental stimulation upon the stereotyped behavior of autistic children.

Two groups of three autistic children, equated for chronological age but differing in IQ and performance MA, were observed for 20-minute sessions. Total duration of time subjects engaged in stereotyped behavior was recorded for each minute. During minutes 6--15, subjects were provided with either minimal or high environmental stimulation. High environmental stimulation was found to increase the mean duration of time the low-IQ group engaged in stereotyped behavior but to decrease the duration for the high-IQ group. The theoretical implications are discussed.

Pneumomediastinum as a complication of extraperitoneal laparoscopic inguinal hernia repair.

A 52-year-old man with left indirect groin hernia was admitted for elective inguinal repair using the totally extraperitoneal (TEP) approach. After an uneventful intubation, TEP repair of the hernia was performed with three midline trocars. Immediately after extubation, the patient noted severe chest pain. There was a decrease in PaO2 saturation, and neck subcutaneous emphysema was detected. There was no emphysema of the abdomen or of the back. A chest film and thoracic computed tomographic (CT) scan confirmed the presence of pneumomediastinum without pneumothorax. The patient was discharged without complications.

Aging jejunal vascular ectasia as a cause of persistent intestinal bleeding.

Undiagnosed gastrointestinal bleeding is a major problem in medical practice. This paper describes a patient with vascular intestinal ectasia who had repeated severe intestinal hemorrhages for two years, and required surgery. Vascular intestinal ectasia was demonstrated radiologically, histologically and by electron microscopy in a 25 cm upper jejunum resection. The absence of ultrastructural alterations in intestinal vessels points out that the term "aging vascular ectasia" (Moore Type I) seems preferable, when Rendu Ossler, Von Willebrand and intestinal hemangioma are discarded.
