[Heterotopic hepatic transplantation in fulminating hepatitis].

Based on a rare case of heterotopic hepatic transplantation (HHT) carried out in a 24 year old woman for fulminant hepatitis of viral origin, the authors present the technique used and the principal post-operative events (rejection, resistant large volume ascites and the clinical course for the liver itself). They discuss the rarity of success in this type of graft, where the causes of failure in man have not been entirely elucidated: the venous pre-existing portal hypertension is probably a very unfavorable factor. The place of this particular type of HHT in cases of acute severe hepatic failure is then proposed: this may produce a smaller operative insult than orthotopic transplantation and, in this respect, deserves consideration when advanced hepatic encephalopathy is present, notably due to delay in finding a suitable graft.

[Campylobacter pylori: diagnostic value of the urease test during endoscopy].

The aims of this prospective study were a) to evaluate the diagnostic value of the urease test for the detection of C. pylori in gastric biopsy specimens, b) to specify the prevalence of C. pylori in a sample of 74 patients from the Grenoble area undergoing upper gastrointestinal endoscopy, c) to analyze the density of bacteria according to the biopsy site (antrum, body, edges of ulcer), d) to demonstrate any possible correlation between the histologic state of the antral and body mucosa and the presence of C. pylori. An antral biopsy was taken for the urease test during endoscopy. Biopsies were also taken from the body, the antrum and the edges of gastric or duodenal ulcers for bacterial and histologic studies, and urease test in the bacterial laboratory. The sensitivity and the specificity of the urease test during endoscopy varied according to the delay in observation of the color change. They were 0.81 and 0.84, respectively, at 2 h 30. The sensitivity and specificity of the urease test in the bacterial laboratory were 0.67 and 0.95, respectively, for the same delay. The global prevalence of C. pylori was 51 p. 100: it was 42 p. 100 in the absence of ulcer, 67 p. 100 in the presence of gastric ulcer, and 71 p. 100 in the presence of duodenal ulcer (p less than 0.05 compared to the group without ulcer).(ABSTRACT TRUNCATED AT 250 WORDS)

[Diagnostic value of gastric pHmetry in duodenogastric reflux].

Several studies have been performed to examine the problem of diagnosing gastroduodenal reflux (GDR). No single method is widely accepted. The aim of this work was to evaluate the diagnostic value of gastric pHmetry in this regard. A gastric aspiration probe attached to a combined glass electrode was placed in the stomach of 24 patients, with its distal tip located between 9 and 12 cm below the cardia. One ml samples of gastric juice were taken from 8 of the patients every 30 min for 15 h and as well as, every time a spontaneous alkalinization (SA) (defined by a pH greater than or equal to 4 for at least 1 min) was observed. The pH of each sample was measured by colorimetry whereas the concentration of total biliary acids (CTBA) was evaluated by the fluorimetric method (Kit Sterognost 3 alpha Flu); pH value measured via the intragastric electrode during aspiration was also recorded (protocol A). Continuous gastric aspiration was carried out in the remaining 16 patients for the entire duration of the test (6 h) which was divided into periods of 20 min. Apart from the parameters evaluated during protocol A, the percentage of time during which the stomach had a pH greater than or equal to 4 was recorded, as well as the quantity of total biliary acids collected over the 20 min periods (protocol B). Correlation studies were carried out using the Kendall tau and Spearman tests. Percentages were compared using the chi 2 test.(ABSTRACT TRUNCATED AT 250 WORDS)

[Changes in blood zinc and serum zinc distribution after surgical intervention].

It is well established that blood zinc concentrations fall postoperatively but documented data does not exist proving a direct relation between the fall in levels and the serious or otherwise nature of surgery performed. This relation was investigated in 25 patients, distributed into three groups as a function of severity of operation, by determining total serum zinc and also its distribution amongst vector proteins and amino acids. Findings indicated that minor procedures such as leg varicose vein stripping failed to affect blood zinc whereas major surgery (extracorporeal circulation) provoked a fall of 47% in blood zinc levels. In addition, this reduction affected only the exchangeable fraction (which is therefore the only one biologically active) of serum zinc. This suggests the need for zinc supplementation to assist healing and re-establish immunity phenomena after major surgery.

[National survey of radiodiagnosis. Methodological aspects (1)].

A national sample of 386 radiological departments and offices representative of a total set of approximately 5 000 have been involved in a statistical survey during the years 81-82. This survey was first directed to the analysis of the production factors related to radiology (number and characteristics of facilities and equipment; medical and paramedical personnel, ...). The radiological activity has then been observed during one week (in June 82) through systematic questionnaires. The information collected on about 13 000 X-Ray examinations consists in characteristics of the population examined, the aims and results of examination, a technical description of procedures (number and size of films; projection; physical parameters, ...). This survey has excluded X-Ray routine examinations (occupational and others); dental examinations, isolated fluoroscopy and ultrasound practiced by physicians.

[National survey on radiodiagnosis. Personnel and equipment (2)].

The total projected number of units (including tables and potters) has been estimated at 16 325 in 1982, at the exclusion of radiological dental systems and unit exclusively devoted to mass X-Ray examinations. Almost half of this total equipment is located in public hospitals (including University hospitals), where the departments have a mean size which is markedly greater than the private sector (clinics and physicians' offices). One of the main feature of the French equipment is the high rate of remote controlled machines (almost 40%). The total labor forces involved directly in this activity has been estimated to 46 000; of which 14 580 are physicians (radiologists or not) and 18 680 are radiographers. The mean productivity, computed in annual mean number of examinations per person (medical and para-medical) is estimated at 1 000. These results are examined and compared throughout the different sectors (public and private; hospital, clinic and ambulatory care).

[National survey on radiodiagnosis. Comparative analysis of the activity of different sectors (3)].

The survey has estimated the global annual production of radiological procedures in France (1982) at 45,4 millions. The large public hospitals (including University hospitals) produce up to 42% of the total; the mean number of annual procedures by X-Ray unit being 4 000, in this sector. The private sector (including clinics and offices) has a production ratio between 2 350 and 2 800 annual procedures by X-Ray Unit; some type of examinations are over represented as compared with the public sector for example lumbar and dorsal spine and digestive. Specialized procedures such as vascular and neuro-radiological represent a quasi monopoly of the public sector. In term of economic behavior, some differences appear between the public and private sectors in the way to account for the procedures to the Social Security System. These are partly due to differences in the complexity of the procedures (for example in the case of abdomen, stomach and upper G.I., the latter being more often performed in hospitals) and to different medical practices (number of films; utilisation of divided films, etc.). The share of procedures executed under the responsibility of a radiologist yields 88% of the total.

[Wirsungorrhage by chronic pancreatitis. About one case (author's transl)].

Studying a case of wirsungorrhage on a 62 years, alcoholic patient, the authors emphasize the difficulty of diagnosis of this upper digestive hemorrhage and the interest of fibroscopy and arteriography during hemorrhagic period. Pancreatectomy is not always possible and an hemostatic intervention is often indicated in emergency cases.
