[Cephalic duodenopancreatectomy with preservation of the pylorus in treating a malignant tumor of Vater's ampulla].

The paper reports on the clinical observation of a patient with mechanical jaundice in which the biliary obstruction was caused by an ampulla of Vater. Cephalic duodenopancreatectomy with preservation of the pylorus was used. Distally the duodenum was excised to its intersection with the mesenteric vessels.

[The reinsertion of the duodenum into the digestive circuit. The indications and surgical technics in operated stomach syndromes].

The authors analyse, retrospectively, the experience of the Clinic of Surgery III. Cluj-Napoca, in the indications and surgical methods for reintroducing the duodenum in the digestive circuit in the syndromes of the stomach operated for benign affections. Between 1974 and 1987, the duodenum was reinstated in the digestive circuit in 37 patients, operated previously for duodenal ulcer (32 cases), gastric ulcer (3 cases), syndrome of mesenteric clip (2 cases).

[Acute transverse myelitis. Clinical and neuroradiological follow-up of a case in a child].

The case of a ten years old boy who presented a sudden onset of tetraplegia is discussed. The benign clinical evolution, under corticosteroid therapy, the negativity of biohumoral examinations of the cerebrospinal fluid and the improvement of the NMR pictures allow the diagnosis of acute spinal myelitis. In the paper are also presented the neuroradiological pictures of myeloCT and NMR; the last one can, for its sensibility, discover little variations in the water contents of the nervous tissue and for its harmlessness can be used for serial examinations.

Sphincteroplasty of the sphincter of Oddi in the treatment of benign distal obstructions of the bile duct. A prospective study of 70 cases managed by a original surgical technique.

Seventy patients in whom sphincteroplasty was performed by an original technique are presented. In 65 cases the indication was stenosis of the sphincter of oddi, associated or not with cholelithiasis or hepatic hydatid disease. There were relative indications in another 5 patients.

First evidence for polyamine conjugation mediated by an enzymic activity in plants.

An enzyme activity, found for the first time in plants, mainly located in the 22,000g supernatant of the crude extract of sprout apices of Helianthus tuberosus L. cv OB1 tubers, is able in vitro to covalently bind polyamines to endogenous substrates of different molecular weights. The major assay parameters, such as pH, dithiothreitol, and extract concentrations were optimized.

[Gadolinium DTPA in magnetic resonance. Clinical experience in intracranial pathology].

Sixty-seven patients with various intracranial pathologies were studied using Gd-DTPA as a contrast medium applied to MRI. This paramagnetic substance was well tolerated by all patients, and proved particularly useful in improving the diagnosis of extra-axial tumors, in which a rich enhancement was always present. Gd-DTPA allowed a better definition of the tumor outlines, as well as its differentiation from edema, and the demonstration of its relationship to brain parenchyma and cerebral vessels.

Effects of mesoglycan sulfate on the arterial elastic module.

Ten patients with peripheral obstructive arterial disease (POAD) in stages I and II according to Leriche-Fontaine, were subjected to therapy with mesoglycan sulfate (60 mg/day for twenty days), to evaluate the effect of the drug on the elastic module of the arterial wall. The wall elasticity was deduced from some Doppler velocitographic indices (arterial dynamics index, resistance index, perfusion pressure index, tibial distensibility index); from the analysis of systolic, protodiastolic, and end diastolic velocity variations; and from computerized analysis of the Doppler sound spectrum. The results show a significant improvement of arterial wall elasticity, which suggests a rational use for the drug in the initial stages of peripheral obstructive arterial disease.

Roux-en-Y gastrectomy: early and late results.

Results obtained in 16 patients by Roux-en-Y gastrectomy (Moskowicz procedure) are presented. According to Langhans a high gastrectomy ascending on the lesser curvature to 2 to 3 cm below the cardia and unaccompanied by a sectioning of the vagal branches was performed. The Roux-en-Y resection was used only in exceptional situations, being preferred to the standard Billroth II operation in order to avoid the biliopancreatic reflux into the gastric remnant.

A case of cortical blindness due to carbon monoxide poisoning.

We report a case of cortical blindness occurring 7 days after acute CO poisoning with no other neurological or psychic deficits apart from denial of the blindness with visual confabulation and slight loss of retentive memory. There was scant correlation between the course of the clinical pattern, which cleared completely within 6 days, and the electroencephalographic pattern with marked and diffuse slowing, which did not recede completely during 3 months observation. CT scanning of the skull, initially within normal limits, displayed 2 weeks later a faint but diffuse hypodensity of the white substance, more marked in the occipital region, which was no longer present 80 days after the first scan.

Choledochoduodenostomy in the treatment of benign biliary tract disease.

Of 3656 surgical interventions in benign biliary tract diseases performed over 8 years, 58 were choledochoduodenostomies. The assessment of the results reveals that after having performed the Finsterer procedure, 7 fistulae and two anastomotic stenoses have been encountered. The operative mortality was 6.

[Hemorheological changes during exercise].

It is now necessary to study the macro- and microcirculatory modifications of the organism following the stress. We have devoted our attention to the hemorheological parameters, which have been evaluated in a group of ten sedentary subjects, of fourteen athletes under twenty years of age, and of ten subjects whose age was over thirty, who carry on physical unbroken performance. We have evaluated the modifications of total blood viscosity and of red blood cell deformability after an ergometric test.
