BACKGROUND AIMS Mesenchymal stromal cells (MSCs) have been reported to be a promising cell source in cell therapy, and large amounts of MSCs can easily be isolated from human amnion. Therapeutic irradiation for intra-pelvic cancer often causes radiation proctitis; however, there is currently no effective treatment. We therefore investigated the effect of transplantation of human amnion-derived ...

Ulcerative proctitis (UP) is a common condition in adult patients and can be very difficult to treat. This review considers critically the definition of this entity, its epidemiology and course, and the modes of therapy currently available. Therapies currently in development are considered as well.

One hundreds seventy-one homosexual men, 96 of whom had symptoms suggestive of proctitis and 75 of whom had no such symptoms, were consecutively enrolled in a study of the prevalence, clinical spectrum, and histopathology of Chlamydia trachomatis rectal infections. C. trachomatis was isolated from the rectums of 14 men. Three of the isolates, which had lymphogranuloma venereum (LGV) immunotypes...

The clinical and pathological findings in a group of 260 homosexual men comprising 10% of a private proctologic practice are reviewed. A clinical pattern of anorectal and colon diseases encountered with unusual frequency in these homosexual patients is termed the gay bowel syndrome. The clinical diagnoses in decreasing order of frequency include condyloma acuminata, hemorrhoids, nonspecific pro...

BACKGROUND/AIMS It is known that ulcerative proctitis might show extension, but in practice, patients with proctitis are not considered as important with regard to regular follow-up and treatment. The aim of this study was to evaluate the extension of ulcerative colitis cases limited to the rectum and compare them with the patients with rectosigmoid and left colonic ulcerative colitis for their...

To study the effect and mechanism of Baitouweng decoction, mesalamine its combination with an enema in treatment ulcerative proctitis rats is objective study. The were divided into seven groups: Control (Normal), model (ulcerative proctitis), mesalamine, lowdose decoction combined medium-dose high-dose group. Except for control group, all induced a 5 % acetic acid solution proctitis. severity w...

Radiation proctitis, an inflammation and damage to the lower part of colon, is a common adverse event of the radiotherapy of tumors in the abdominal and pelvic region (colon, prostate, cervical). Several Mn(III) porphyrin-based superoxide dismutase mimics have been synthesized and successfully evaluated in preclinical models as radioprotectants. Here we report for the first time the remarkable ...

BACKGROUND AND PURPOSE Radiation proctitis is a potential complication following pelvic radiation therapy. There are no standard treatments and treatment outcomes are unpredictable. We report our experience with the use of hyperbaric oxygen treatment (HBOT) for radiation proctitis cases refractory to standard medical or laser therapy. PATIENTS AND METHODS During the period 2000-2004, 10 patie...
