[Revascularization of the corpora cavernosa in vasculogenic impotence].

The vasculogenic erectile impotence, caused by occlusion and/or stenosis of arteries supplying the penis, is the most common cause of erectile failure in men over 40 years. The vasculogenic impotence is more found by peripheral vasculopathies like diabetes mellitus and nicotine abuse. It is important that the precise site of vascular lesion is established with selective arteriography of the hypogastric-internal pudendal axis.

[Dysphagia associated with aorto-cardiac compression on the distal esophagus: a rare event but not exceptional in the elderly].

Among the pathologies responsible for dysphagia in the elderly, the aortic compression on the distal oesophagus awakens a certain clinical interest. Cipho-lordosis, which is often present in aged females, worsens the effects of this compression causing other kinkings on the oesophagus already hypokinetic because of the age (presbyoesophagus). This illness often shows scare symptoms, but sometimes requires a pneumatic dilation to allow normal food assumption of the patient.

[An anatomicoclinical case of lipoma of the sigmoid].

The authors describe a case of a submucosal lipoma of the large intestine. Family, physiological, and remote anamnesis of the patient was negative to inflammatory or neoplastic intestinal diseases. The symptomatology was not characteristic like the several cases reported in the literature, by abdominal cramps, subocclusion or total occlusion crisis and rectal bleeding.

Arterial repair after microvascular anastomosis. Scanning and transmission electron microscopy study.

In order to study the morphological aspects of endothelial regeneration and vascular wall reaction after microvascular anastomosis, rat femoral arteries were sectioned and successively sutured (end-to-end anastomosis) with microsurgical techniques. Control arteries and anastomosed vessels (recovered after 1, 4, 7, 14, 21, 30, 60, 120, 180 and 360 days) were studied by means of scanning (SEM) and transmission electron microscopy (TEM). The reendothelialization phenomena started after 7 days and were mainly evident at 21 days.

[Preparation of the colon for endoscopic examinations. A clinical study].

The paper gives a short critical bibliographic review of colonic preparation for endoscopy, focusing on the out-patient use of gastrointestinal endoscopy. A method of preparation based on dietary restrictions plus cathartics is proposed that allows the number of enemas used to be reduced to a minimum. The results obtained in 265 out-patients undergoing colonoscopy confirm the efficacy, practicality and tolerability of the method.
