    Notes: Abstract PURPOSE: This study was designed to analyze critically the short-term and long-term outcome of sphincteroplasty and to identify high-risk factors. METHODS: Eighty-six patients with fecal incontinence associated with an ultrasound defect of the external anal sphincter were treated by anal sphincteroplasty. Clinical and physiologic assessment was made before surgery, and clinical evaluation was made three months and an average of 40 months after surgery. RESULTS: The evaluation of 86 patients three months after surgery showed that 42 patients were totally continent (49 percent), 28 were incontinent for gas (33 percent), and 16 still had fecal incontinence (19 percent). Seventy-four patients (86 percent) were contacted 40 months after surgery. Twenty-one patients (28 percent) were totally continent, 17 were incontinent to gas (23 percent), and 36 were incontinent to feces (49 percent). Forty-six percent of patients felt they were clearly improved after surgery. Poor results were associated with an internal anal sphincter defect. CONCLUSIONS: Our study suggests that in the long term, one-third of patients are totally continent after sphincteroplasty. One-half of patients are satisfied, but only if their incontinence to feces has totally disappeared. Results of sphincteroplasty deteriorate with time. One factor in poor prognosis is the presence of an associated defect of the internal anal sphincter.

    Notes: Résumé Les études de liaison aux récepteurs dopaminergiques ont révélé la présence de deux types de récepteurs, D1 et D2, dans la rétine. Des micro-autoradiographies de rétines humaines ont confirmé la répartition des récepteurs dopaminergiques dans les couches plexiformes. Le piribédil, agoniste dopaminergique, se lie aux récepteurs D2 tandis que son métabolite (S584) déplace préférentiellement les radio-ligands spécifiques des récepteurs D1. Ces résultats démontrent que le profil pharmacocinétique du piribédil est voisin de celui de la dopamine, avec notamment une action directe sur les récepteurs de cette substance. Instillé dans l'œl de lapin, le piribédil pénètre rapidement dans les structures oculaires, s'accumule dans les épithéliums pigmentés (iris-corps ciliaire et choriorétine), puis est rapidement éliminé. Des autoradiographies de l'œil entier ont confirmé cette distribution et ont montré que les concentrations atteintes étaient compatibles avec l'affinité du piribédil pour les récepteurs dopaminergiques rétiniens.

    Notes: Abstract Chronic anoperineal pain without any apparent etiology may be caused by compression of the pudendal nerve. This presentation illustrates the course of the pudendal nerve and the technique of computed tomography-guided infiltration of the nerve.
