SynopsisA survey of 355 college students was carried out to determine the prevalence of the psychiatric disorder bulimia (the binge-eating syndrome). Results of the survey indicate that, within the normal college population, 13% experienced all of the major symptoms of bulimia as outlined in the DSM-III. Within the bulimic population, 87% were females (19% of the female population) and 13% were males (5% of the male population). Although self-induced vomiting may accompany other symptoms of bulimia, the results suggest that self-induced vomiting is not a necessary symptom for diagnosis. A significant relationship between laxative use and self-induced vomiting was detected. These forms of behaviour, termed purging behaviour, occurred in an average of 10% of the students. Individuals who experienced the symptoms of bulimia had a history of being overweight or tended to be in the upper portion of their normal weight range (age, sex, and weight corrected) when compared with those individuals who had not experienced the symptoms of bulimia. No significant weight history differences were detected between vomiters and non-vomiters.

SUMMARYThe authors describe relationships between age and ratings of signs and symptoms in 40 manic inpatients. Soon after admission, some psychopathologic features were less prominent in older patients. In older patients, after two weeks of treatment with lithium and neuroleptics, there was greater residual total psychopathology, higher ratings of some clinical features, and less change in total psychopathology and some clinical features. Older patients were hospitalized longer. Ageing may alter manic psychopathology and treatment response. The authors emphasize the need for prospective studies that include geriatric patients.

A variety of physiological abnormalities are associated with the disorder, anorexia nervosa. In this study 40 anorexia patients were studied for hematological, electrolyte, lipid, and serum enzyme aberrations when they entered a treatment study in the emaciated state and again after nutritional rehabilitation. This article discusses all those metabolic aberrations which revert to normal with nutritional rehabilitation and those aberrations which occur in the course of weight gain.
