Bulimia nervosa with and without a history of anorexia nervosa.

This study compared two subgroups of women of normal weight with bulimia nervosa: those with a history of anorexia nervosa and those without such a history. Those with a history of anorexia nervosa indicated a desired body weight significantly lower than those without the history. Those with a history of anorexia nervosa were more likely to abuse laxatives and less likely to self-induce vomiting. Both groups reported feeling fat and worrying a great deal about weight and shape issues.

Shoplifting in bulimia nervosa.

This study compared the shoplifting patterns of 27 bulimic and 25 nonbulimic shoplifters. Bulimic shoplifters often stole food, but usually also stole other items. Nonbulimic shoplifters reported starting to steal at an earlier age, weighed more than bulimic shoplifters, and were more likely to endorse antisocial reasons for shoplifting.

Anatomic models and phantoms for diagnostic ultrasound instruction.

The preparation and application of anatomic models and phantoms to facilitate learning diagnostic ultrasound is described. Imaging with diagnostic ultrasound requires mastery of many skills, along with knowledge of sound-tissue interactions which contribute to the formation of diagnostic images and artifacts. Understanding the genesis of artifacts encountered during ultrasound scanning can avoid misinterpretation and aid diagnosis. In addition, development of machine related knowledge and skills, including manipulation of the transducer and the selection of correct settings for variables such as gain, power, time-gain compensation, and transducer type, is dependent on an understanding of how these factors affect the image. The normal appearance of an organ relates to both its echogenicity and morphologic characteristics, and confirmation of the nature of an abnormality often requires ultrasound guided biopsy. The use of anatomic models and phantoms in ultrasound instruction allows principles to be demonstrated, knowledge acquired, and biopsy procedures practiced and mastered in a controlled setting. This can minimize live animal use, and enhance the knowledge base and skills of the clinician prior to applying this diagnostic technique to the clinical patient.

The epidemiology of eating disorders.

Further clarification of the epidemiology of eating disorders is essential. The high prevalence of these disorders, which appears to be increasing in women, indicates that high priority should be placed on the effective use of treatment resources through knowledge of the risk factors and clinical course of these illnesses. It seems clear that sociocultural emphasis on thinness in our society contributes to the risk factors of sex, age and social class. Prospective studies following a large number of subjects at high risk will be necessary to define more specific risk factors for the development of these disorders.
