TL;DR: Model fitting indicated that there is a powerful role of the environment in shaping women's attitude towards weight, shape, eating and food, and it seems likely that environmental manipulation can be effective in the prevention of bulimia nervosa.
Abstract: Background. This study seeks to identify the genetic and environmental risk factors for the overvalued ideas that are characteristic of bulimia nervosa, using a biometrical model fitting approach with twin data. Methods. The Eating Disorder Examination (EDE), which can be used to gain continuous measures of dietary restraint, eating concern, weight concern and shape concern, was administered to 325 female twins, both monozygotic (MZ) and dizygotic (DZ). For each subscale, questions were asked concerning the month prior to interview and lifetime prevalence ('ever'). Results. Model fitting indicated that there is a powerful role of the environment in shaping women's attitude towards weight, shape, eating and food, ranging from 38% to 100% of the variance. For all subscales, with the exception of weight concern, the best explanation for individual variation was one that incorporated additive genetic and non-shared environmental influences. In contrast, model fitting indicated that non-shared and shared environmental influences best explained the variance of weight concern. Conclusions. With the exception of the Shape Concern subscale, environmental factors make a greater contribution than genetic factors to the development of the overvalued ideas that are seen to be one of the triggers for the development of bulimia nervosa. Given this substantial role of the environment influences, it seems likely that environmental manipulation can be effective in the prevention of bulimia nervosa.

TL;DR: In this paper, case reports of two subjects who developed anorexia nervosa following gastric reduction surgery for morbid obesity are described. And the implications for the selection of subjects for gastric reductions surgery and management after surgery are discussed.
Abstract: Anorexia nervosa and morbid obesity are popularly considered to be opposite ends of the eating disorder spectrum. Research and clinical experience, however, suggest common psychological factors in a subgroup of obese people. This paper details case reports of two subjects who developed anorexia nervosa following gastric reduction surgery for morbid obesity. Clinical profiles, treatment, and outcome are reported. Psychological similarities between morbid obesity and anorexia nervosa in these subjects are explored. Implications for the selection of subjects for gastric reduction surgery and management after surgery are discussed.

TL;DR: Examination of treatment issues relating to a woman diagnosed with both IBS and PD (with agoraphobia), where therapy for PD was disrupted by IBS symptoms, finds group therapy was initiated for IBS, and this was associated with a large decrease in general anxiety and depression, and an increase in confidence concerning management of the pain caused by the IBS.
Abstract: Evidence suggests that cognitive behaviour therapy is the treatment of choice for both irritable bowel syndrome (IBS) and panic disorder (PD). The present study examines the treatment issues relating to a woman diagnosed with both IBS and PD (with agoraphobia), where therapy for PD was disrupted by IBS symptoms. Group therapy was then initiated for IBS, and this was associated with a large decrease in general anxiety and depression, and an increase in confidence concerning management of the pain caused by the IBS. This finding is discussed with respect to its possible implications for the treatment of people suffering both IBS and PD.
