[Occlusion caused by colo-rectal carcinoma: personal experience].

In the last 12 years 25 patients affected with obstruction from colorectal carcinoma were treated. Mortality following simple colostomy was not different from that of surgical resections (25% vs. 14% in Authors' experience).

[Local recurrence after mastectomy by the Patey technique. Analysis of a personal caseload and characterization of risk factors].

The Authors report the incidence of local relapsing in a group of 362 patients who underwent Patey's mastectomy from 1974 to 1985. The overall incidence was 9.6%.

A safe and rapid esophagojejunoduodenostomy after total gastrectomy.

Some modifications to the technique of Longmire-Mouchet after total gastrectomy are proposed. They permit a more rapid and safe surgical treatment.

Chronic atrophic gastritis and risk of N-nitroso compounds carcinogenesis.

Chronic atrophic gastritis is considered a precancerous condition for carcinoma of the stomach. To evaluate the correlation between progressive alterations in the mucosa and gastric juice microenvironmental factors, retained involved on N-nitroso compounds carcinogenesis, detailed analyses of biochemical and microbiological parameters such as pH, total viable counts (TVC), nitrate reductase positive bacterial counts (NRPBC), nitrite (NO2-) and thiocyanate (SNC-) levels, were carried out on 56 fasting gastric juices samples obtained at endoscopy from 28 patients with chronic atrophic gastritis (CAG), 14 with gastric cancers (GC), and 14 normal controls (NC). The mean values of pH, nitrite, TVC, and NRPBC were significantly lower in the juices of NC than in those of CAG and GC patients.

The microflora of the gastric juice after Billroth I and Billroth II partial gastrectomy.

Detailed analyses of biochemical and microbiological variables such as pH, nitrite concentration, total viable counts (TVC), nitrate reductase-positive bacterial counts (NRPBC), and identification of microorganisms were carried out on 76 fasting gastric juice samples obtained at endoscopy from 64 patients previously submitted to partial gastrectomy (22 end-to-end Billroth I, 42 Billroth II/Reichel-Polya) and from 12 normal controls. Samples from normal controls were sterile, but bacteria were detected in the juice from all the operated patients. Significantly higher mean pH values and nitrite levels (p less than 0.

The management of infancy and childhood intussusception in a department of general surgery.

The experience with 24 intussusceptions observed in a Department of General Surgery has been reviewed. The delay between onset of symptoms and hospitalization was less than 24 hours in 58% of cases, from 24 to 48 hours in 28%, and more than 48 hours in 14% of children. 23 patients were submitted to barium enema.

Evaluation of carcinoembryonic antigen levels in gastric juice, stomach mucosa and plasma in high-risk and gastric cancer patients.

The aim of this study is to compare the levels of carcinoembryonic antigen (CEA) in the gastric juice, stomach mucosa and plasma of gastrectomy patients at risk of developing cancer with those in normal controls and gastric cancer subjects. Blood samples, gastric juices and biopsy material were taken from 52 patients (8 normal, 10 gastric carcinomas, 24 gastroresected according to Billroth II and 10 according to Billroth I). No significant correlation was found between age, sex or smoking habits and CEA levels in plasma, gastric juice or stomach mucosa.

The role of presynaptic beta-receptors in Raynaud's disease.

This report concerns the results of a study carried out to show the presence of presynaptic Beta adrenergic receptor supersensitivity in RD patients and the possibility to prevent or at least decrease this supersensitivity with Beta-blocker treatment. It is shown that the paradoxical vasoconstriction response to ISP infusion can be prevented in RD patients by the acute administration of Beta-blocker, such as Atenolol or DL Propranolol. Moreover, chronic treatment with the correct Beta-blocker was seen to prevent angiospastic crisis in these patients.
