Is serum gentamicin level a good predictor of graft injury in intestinal transplantation?

INTRODUCTION: Following intestinal transplant (SBT), the early diagnosis and treatment of rejection is a major management aim. The diagnosis of rejection is based on histology of stomal biopsies. Oral gentamycin (2.5 mg/kg) was used for selective decontamination of the digestive system. Our hypothesis was that gentamycin might be absorbed in the presence of graft dysfunction. AIM: Our goal was to assess the correlation between serum gentamycin level and the health of the intestinal graft. SUBJECTS AND METHODS: Among 33 SBT performed from 1993 to 2005, serum gentamycin levels were performed once weekly or more often when there was a suspicion of rejection. All data were analyzed retrospectively. RESULTS: Adequate trough levels were achieved for only 23 patients, six of whom had histologically proven rejection and only one did not have a raised gentamycin content. Five patients with raised levels but no rejection included two with severe intestinal ischemia and three with bowel obstruction/ileus. Four of the five patients required laparotomies. CONCLUSION: We concluded that in our study raised serum gentamycin levels were a good predictor of rejection or significant injury to the graft.

Working alongside the general practitioner: a child psychiatric clinic in the general practice setting.

A monthly child psychiatric clinic was established in a primary health care centre in order to offer a more accessible service to patients, and to improve liaison with primary health care professionals. Compared with the base child guidance unit, at the health centre there was a better first attendance rate, a much higher proportion of referrals from health professionals especially general practitioners, and an increased proportion of younger children referred. If further follow-up was necessary at the child guidance unit the attendance rate was very good. The service provided, although not reducing the need for a main multidisciplinary base, offered an acceptable and accessible opportunity for children with psychological problems to be assessed and treated, and for the referring professionals to have easy communication with the child psychiatrist.

Intestinal crypt lesions associated with protein-losing enteropathy in the dog.

Six dogs were diagnosed with protein losing enteropathy (PLE). There was no evidence of inappropriate inflammatory infiltrates or lymphangiectasia in multiple mucosal biopsies of the small intestine of 4 of the dogs. The 5th and 6th dogs had obvious lymphangiectasia and a moderate infiltrate of inflammatory cells in the intestinal mucosa. All 6 dogs had a large number of dilated intestinal crypts that were filled with mucus, sloughed epithelial cells, and/or inflammatory cells. Whether PLE occurs in these dogs because of protein lost from the dilated crypts into the intestinal lumen or whether the dilated crypts are a mucosal reaction due to another undetermined lesion that is responsible for alimentary tract protein loss is unknown. However, when large numbers of dilated intestinal crypts are present, they appear to be associated with PLE even if there are no other remarkable lesions in the intestinal mucosa.
