Field theory in two-time physics with N=1 supersymmetry.

We construct N=1 supersymmetric (SUSY) field theory in 4+2 dimensions compatible with the theoretical framework of two-time (2T) physics and its gauge symmetries. The fields are arranged into 4+2 dimensional chiral and vector supermultiplets, and their interactions are uniquely fixed by SUSY and 2T physics gauge symmetries. In a particular gauge the 4+2 theory reduces to ordinary supersymmetric field theory in 3+1 dimensions without any Kaluza-Klein remnants, but with some additional constraints in 3+1 dimensions of interesting phenomenological relevance.

[Transperineal repair of rectocele with prosthetic mesh. A prospective study].

Purpose: To assess the long term results of a transperineal repair of rectocele with a prosthetic mesh and the criteria for selecting the patients.

Methods: Twenty-five consecutive patients (median age: 60 years) with a symptom-giving rectocele have been operated upon. Indication for surgery was: an obstructed defecation (N = 22); a fecal incontinence (N = 1); a pelvic heaviness with dyspareunia (N = 1) or a severe rectal syndrome (N = 1).

Prosthetic rectopexy to the pelvic floor and sigmoidectomy for rectal prolapse.

Background: Full thickness rectal prolapse in young adults with normal pelvic floor is a disease in which the rectum is exceedingly long and mobile. Surgical treatment should correct both anatomical defects by combined rectopexy and colonic resection, which is expected to be less constipating than rectopexy alone. The aim of this study was to describe an original procedure of rectopexy to the pelvic floor with prosthetic material combined with sigmoid resection, and to evaluate prospectively anatomical and functional results.
