RESUMO

A barium enema is a diagnostic and therapeutic procedure commonly used for colon and rectum problems. Rectal perforation with extensive intra- and/or extraperitoneal spillage of barium is a devastating complication of a barium enema that leads to a significant increase in patient mortality. Due to the low number of reported cases in recent scientific literature and the lack of experience with the management of these cases, we would like to present our treatment approach to a rare case of retroperitoneal contamination with barium, followed by its intraperitoneal involvement during a diagnostic barium enema. Our experience with long-term management of the patient and the good outcome will be depicted in this paper.

RESUMO

Wound healing has always been among important and crucial subjects in medicine. Morphine dependency has also been a social and health problem in the Middle East. This study was aimed to investigate the effects of morphine dependency on pro-inflammatory and fibroblast cell recruitment, as well as reepithelialization and the revascularization processes involved in secondary intention wound healing in rats. A full-thickness wound [2×2 cm in diameters] was created on the dorsum of two groups of rats, a control group and a second group consisted of morphine dependent rats. During the first 14 days of post wounding the wound was excised consecutively at priorly planned days with peripheral margins of normal skin. The specimens were evaluated by two pathologists, who were blind to the study design, and the cellular population, re-epithelialization and revascularization were reported by them. Histological examination of the wound tissue showed evidence of increased population of fibroblasts and a plateau or decreased recruitment of macrophage and neutrophile cells. In the dependent group re-epithelialization was observed to be enhanced significantly in comparison to the control group while having an inhibitory effect on revascularization. The present study demonstrates that morphine dependency enhances re-epithelialization as well as tissue recruitment of fibroblasts; thereby probably enhancing secondary intention wound healing
