PURPOSE: This study prospectively assessed the functional results, particularly anal sphincter impairment, following transanal repair of rectocele for chronic intractable constipation. METHOD: Twenty-one consecutive women (mean age, 47.7 (standard error of the mean, 2.7) years) had the diagnosis of rectocele obstructing defecation made on synchronized anal manometry, electromyography, and cinedefecography. All underwent a standardized transanal repair with controlled anal stretching (maximum of 4 cm) from self-retaining anal retractors. The clinical function and anorectal manometry were assessed before surgery and were repeated six months later. RESULTS: All 21 patients were subjectively satisfied with the relief from constipation after surgery. There were significant improvements in the straining at defecation (before, n = 19; after, n = 3; P = 0.001), need to digitate per vagina (before, n = 16; after, n = 0; P = 0.001), stool frequency (before, 3.8 (0.7) times weekly; after, 8.6 (1.2); P = 0.004), and laxative requirements (before, n = 7; after, n = 0; P = 0.03). Although none were clinically incontinent, there was a mean 28 mmHg impairment in resting (P < 0.05) and 42.6 mmHg impairment in maximum squeeze anal pressures (P < 0.05) after operations. There was no other morbidity. CONCLUSION: Transanal rectocele repair effectively improves constipation problems, at the risk of impaired anal sphincter function. Although clinical incontinence was minimum, an alternative approach to rectocele repair should be considered when anal sphincters are lax.

Impulsive and compulsive self-injurious behavior in bulimia nervosa: prevalence and psychological correlates.

A specific link between self-injurious behavior and bulimia nervosa has been observed. In affective spectrum disorders, some authors propose a distinction between impulsive and compulsive self-injurious behavior. One of the aims of the present study is to examine how different kinds of self-injurious behavior, including purging behavior, may be classified in bulimia nervosa. The clinical impact of the different types of self-injury will be studied. The subjects of the study were 125 consecutive patients with bulimia nervosa, diagnosed by DSM-IV criteria. Subjects were evaluated by means of a semistructured interview and self-report questionnaires (Eating Disorders Inventory and Hopkins Symptom Checklist). In our sample, the distinction between compulsive and impulsive self-injurious behavior appeared to be confirmed by a principal component analysis. Self-induced vomiting loaded on the compulsive dimension and laxative abuse on the impulsive dimension. To study the clinical impact of the two kinds of behavior, bulimic subjects were divided according to their position in the two dimensions. The presence of impulsive self-injurious behavior is associated with a history of sexual abuse and with higher scores on the Symptom Checklist. The presence of both impulsive and compulsive behavior is associated with greater depression, whereas the presence of impulsive features in the absence of compulsive ones seems to be linked to a longer duration of illness and to a higher dropout rate. Both compulsive and impulsive self-injurious behaviors are associated with a greater lack of interoceptive awareness.

Recurrence of symptoms in Clostridium difficile infection--relapse or reinfection?

Wilcox MH, Fawley WN, Settle CD, Davidson A.

We have fingerprinted Clostridium difficile isolates from patients with symptomatic recurrences of infection, using random amplified polymorphic DNA (RAPD). The medical records of 55/79 patients were examined, from whom multiple C. difficile-positive faeces were received during hospitalization at least five days, but no more than two months, apart. In 20 of these cases symptoms either did not recur (i.e., absent for at least three days between episodes), or were explainable by other causes, such as laxative administration. Of the remaining 35 patients, 27 sets of C. difficile isolates (23 pairs and four triplicates) were available for RAPD fingerprinting. Differing C. difficile DNA fingerprints (at least three major bands difference) were obtained for 15/27 patients, and hence at least 56% of the clinical recurrences of infection were in fact due to re-infection as opposed to relapse. Since we found that an endemic C. difficile clone was present in 18 out of 27 patients (67%) and accounted for 53% (31/58) of all isolates, it is probable that the majority of symptomatic recurrences are in fact re-infections, with either a different or the same C. difficile strain. We conclude that more attention must be given to preventing the re-infection of C. difficile symptomatic patients. Isolation of symptomatic individuals is the preferred option for the protection of other patients, but measures must be taken to ensure that further strain acquisition by the index cases does not occur.
