Five cases of surgically treated unrestrainable pulmonary haemorrhage are described. The satisfactory results obtained show that pulmonary exeresis, in some cases of haemorrhages, is the only effective method for saving the patient's life and removing the anatomic cause of the haemorrhage.

The objective of this study was to compare the clinical and bacteriologic efficacy and safety of cefodizime 1 g intramuscularly (IM) once daily (group A) versus cefodizime 1 g IM twice daily (group B) and versus ceftriaxone 1 g IM once daily (group C) in patients with community-acquired pneumonia. A total of 298 patients, affected by bronchopneumonia or pneumonia with known or suspected bacterial cause, new focal signs on examination of chest, and radiographic evidence of a recent infiltrate, were randomized in three comparable groups. The infection was rated as mild, moderate, or severe. A total of 283 patients were assessable for efficacy: 95 in group A, 94 in group B, and 94 in group C. Mean (+/- SD) duration of treatment was 5.96 +/- 1.39 days in group A, 6.24 +/- 1.57 days in group B, and 6.66 +/- 1.95 days in group C. Symptoms such as purulent sputum, cough, and dyspnea improved significantly after treatment in all groups; temperature normalized by about day 3. Clinical efficacy was rated good in 94.74% of patients in group A, in 92.55% in group B, and in 87.23% in group C. Positive bacteriologic cultures were obtained before treatment from 144 patients: bacteriologic responses were rated good in 98.11%, 98.08%, and 92.80% in groups A, B, and C, respectively. No significant differences were found between the three treatment groups for any measures of clinical efficacy. No serious adverse event occurred in any of the groups. We conclude that cefodizime 1 g IM once daily is an effective dosing regimen in the treatment of patients with community-acquired pneumonia.

Postoperative thromboembolic complications do present an underestimated problem whenever their detection simply relies upon individual clinical judgement. Major abdominal operations are at increased risk of pulmonary embolism (PE) and deep vein thrombosis (DVT), mostly in advanced age, overweight subject, and in patients with cardiac or malignant diseases, or with previous venous diseases. Such patients may benefit from a peri- and postoperative prophylaxis with chemical or mechanical procedures, as a recent meta-analysis seems to suggest. In our experience, a randomized, multicentric clinical trial with defibrotide (DF) versus calcium-heparin (CH) was realized with the aim of evaluating their effectiveness and side effects in the prophylaxis of PE and DVT after major abdominal surgery; 1296 patients were randomly assigned to i.v. DF (400 mg.) or subcutaneous CH (0.2 ml. = 5000 U.I.) given one hour prior to operation and twice daily for seven days postoperatively. Definitive evaluation was carried out on 1212 patients (610 patients in DF and 602 in CH group, respectively) who completed the prophylaxis and monitoring schedule acceptably. One PE (0.16%) and 38 DVT (6.2%) were detected in DF group while 2 PE (0.33%) and 40 DVT (6.6%) were reported in CH treated patients. Post-operative blood loss was 578 +/- 150 cc. (median +/- S.E.M.) in DF group and 604 +/- 123 in CH group (p = n.s.). Wound hematoma was observed in 69 patients (5.7%): 20 (3.2%) in DF and 49 (8.1%) in CH group of patients (CHI-Square = 12.44; p = 0.0005); a significant post-operative decrease of RBC, WBC, Platelet count, and Fibrinogen was computed in both groups (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
The aim of the present study was to evaluate the gastro-duodenal motility coordination, both during the interdigestive phase and after antroduodenal volumetric stimulus. It has been proved that it is possible to evoke the peristaltic gastric activity by stretching the gastric walls. Thus, the Authors simulated the mechanical conditions of the meal by inflating air into the antrum. They studied 5 healthy volunteers, whose age averaged 43 +/- 22.85 years. A 120 cm probe provided with two balloons at 7 and 21 cm from the distal end, and with 7 open-tips for manometric recording, was positioned by endoscopic way. The Authors were able to evaluate the Motor Antral Threshold (i.e. minimum air volume able to evoke an antral motor reflex), obtained by means of the antral inflatable balloon. The average values of this threshold showed to be 35 +/- 5 ml of air. While keeping the duodenal balloon inflated, the repetition of volumetric antral stimulus did not show any Motor Antral Threshold. This threshold showed up again with similar volumes in every patient after deflating the duodenal balloon. The results obtained suggest the existence of a negative duodenal-antral feed-back control on gastric emptying.
The formation of multiple aneurysms in the midportion of Dacron grafts has been reported only twice in the surgical literature. In the present case, three aneurysmal dilatations developed 6 years following an orto-femoral Dacron graft implantation. Multiple structural defects in the Dacron prosthesis appear to be the most likely cause of the graft failure.
From 1977 through 1984, 58 arterial reconstructions using glutaraldehyde-tanned human umbilical vein (H.U.V.) grafts were carried out: 41 femoropopliteal, 4 composite aortopopliteal (a Dacron graft was inserted proximally), 5 femorotibial, 6 axillofemoral, 1 femorofemoral, and 1 iliofemoral bypass. Autogenous saphenous vein was absent or inadequate in all patients. Limb salvage was the primary indication for surgery (89.7%). Five and 8 years cumulative patency rates were 42.8% and 35.1% respectively for all H.U.V. by-passes and 52.4% and 41.9% respectively for femoropopliteal by-passes. Four out of the 5 femorotibial by-passes failed during the first month following surgery. Two of the 6 axillofemoral and 3 of the 4 composite aortopopliteal by-passes thrombosed within 1 and 3 years after surgery, respectively. Perioperative mortality was 5.1%, while overall mortality was 17.2%. The following conclusions can be drawn from these results: H.U.V. grafts did not achieve cumulative patency rates superior to those reported with autogenous saphenous vein, in limb salvage situations, when the saphenous vein is not available, the H.U.V. graft offers acceptable salvage rates, results from the 8-year follow-up period demonstrate the durability and long-term patency of H.U.V. grafts.
In order to investigate the morphological and functional changes produced in the colonic mucosa after prolonged exposure to gastric juices, 24 colonic patches were implanted on the gastric body and the gastric antrum. The specimens were removed, two, four or six months after surgery, and several morpho-functional changes were observed. These included a gastric-like transformation of the superficial epithelial cells, the presence, exclusively in the colonic patches implanted in the gastric body, of cells with large osmiophilic cytoplasmic granules and a progressive increase in sialomucin secretion with an almost complete disappearance of sulfomucins.

A rare case of acutely thrombosed atherosclerotic aneurysm of the deep femoral artery is herein described. A review of the literature revealed 12 other reported cases of deep femoral aneurysm. However none were treated by resection and replacement using a human umbilical vein graft which was chosen in the present case because the autogenous saphenous vein was not available.
The Authors, after synthetic outline of the new regulations concerning "the release on trust in social service", an alternative measure to that of imprisonment according to law no. 354 of 26 July 1975, take into consideration some of the problems and difficulties which have emerged in the first months of application of this law. This examination is followed by a review of the results of criminological research on the period of probation and of the present aims emerging with regard to this measure, in the countries where it has been tested for some time. The Authors conclude with a critical evaluation of the present regulations and a series of proposals aimed at improving the application of the probation system in social service.
