[Low anterior resection of the rectum using mechanical anastomosis in intestinal endometriosis]. / Resezione anteriore bassa del retto con anastomosi meccanica per endometriosi intestinale.

A case of sigmoid-rectal endometriosis prompted the authors to focus attention on the question of indications for surgery and operative tactics in intestinal endometriosis. In this case, the presence of a pelvic mass which could not be cut away from the intestinal wall without the risk of perforation led to the performance of a low anterior resection of the rectum with mechanical stapler, a choice which was certainly radical but necessary in view of the impossibility of excluding the malignant nature of the mass either macroscopically or extemporaneously.

A simplified method of pig islet isolation.

This study reports a simplified, low-cost, easily performed chemico-mechanical isolation method of the islets of Langerhans. The experimental study was carried out on 15 adult pigs. Our method used collagenase and a digestion chamber for islet isolation and yielded 2,240 +/- 613 islets per g treated pancreas after purification. This demonstrates that the method is reliable and can give satisfactory results.

[Oxiracetam treatment of exogenous post-concussion syndrome. Statistical evaluation of results]. / Trattamento con oxiracetam della sindrome post-commotiva esogena. Valutazione statistica dei risultati.

The aim of the study was to evaluate the clinical use of a GABOB by-product in the treatment of exogenous post-concussion syndrome. Thirty-six patients affected by this syndrome were included in the study and divided into two groups. Patients in the first group were treated with the drug, while patients in the second group were not treated. Variations in the average time taken for symptoms to disappear in both groups showed a statistically significant difference in favour of the drug-treated group of patients. Following an analysis of the results it was possible to affirm that the drug had a statistically significant effect in patients affected by medium-severe symptomatology.
