Images of cecal volvulus from a strangulating fallopian tube: a case report.

UNLABELLED: An unusual case of cecal volvulus arising from a strangulating fallopian tube is presented. The etiology, diagnosis, and management guidelines of this infrequent cause of large bowel obstruction are reviewed. Computed tomography images are included, which demonstrate key features that are pathognomonic for this condition. To our knowledge, this is the first report of gynecologic adnexa giving rise to cecal volvulus. KEYWORDS: Cecal volvulus; Gynecologic and general surgery; Intestinal obstruction.

The mortality rate from anorexia nervosa.

OBJECTIVE: We determined the standardized mortality ratio (SMR) in our anorexia nervosa (AN) patient population. METHOD: We used a cross-sectional design to study an inception cohort (1981-2000) drawn from the provincial tertiary care eating disorders program at St. Paul's Hospital (British Columbia, Canada). All patients who completed their initial assessment for an eating disorder were included in the study. Vital status, date and cause of death from British Columbia Vital Statistics Agency, date of assessment, date of birth, and diagnosis at the time of assessment were collected for each patient. RESULTS: Of 954 patients, 326 diagnosed with AN completed an assessment over the 20 years. The SMR was 10.5 (95% confidence interval [CI] = 5.5-15.5) for AN. DISCUSSION: Some studies in the literature report that AN has the highest mortality rate of any psychiatric disorder in young females. However, others dispute this fact and report an SMR lower than the normal population mortality (SMR = 0.71). Contrary to some reports in the literature, our study confirms a high mortality rate within the AN population.

Early emphysema in patients with anorexia nervosa.

Postmortem studies of patients who died in the Warsaw Ghetto during World War II suggested that death from starvation was associated with pulmonary emphysema. This study re-examines this hypothesis in patients who are chronically malnourished because of anorexia nervosa. Age, smoking history, body mass index, and pulmonary function were measured in 21 subjects with anorexia nervosa and 16 control subjects. Computed tomography (CT) scans were obtained from three regions of the lung (at the level of the aortic arch, the carina, and the posterior position of the eighth rib) using a multislice scanner. The CT measurements of lung density, emphysema, and surface area-to-volume ratio were obtained using the X-ray attenuation values. CT measurements of emphysema were greater in the group that was anorexic than in historical control subjects (p < 0.001). Furthermore, there were significant correlations between the body mass index and the CT measures of emphysema for all the patients and between diffusing capacity and the CT measurements in the patients who were anorexic. A multiple linear regression analysis showed the diffusing capacity was predicted best by the percentage of lung voxels within the large emphysematous changes category. These data demonstrate that emphysema-like changes are present in the lungs of patients who are chronically malnourished.
