Postoperative CT follow-up of aortic dissection.

Computed tomography with contrast enhancement permits noninvasive follow-up of patients treated for aortic dissection. We used CT to examine 52 patients with aortic dissections for up to 14 years postoperatively. The mean interval between surgery and CT was 32 months. Computed tomography demonstrated the aortic graft in 45 patients. Persistent patency of a false lumen was observed in 40 cases. In one case, CT demonstrated extension of the dissection. No rupture or thoracic pseudoaneurysm was noted in our series.

Sequential mammary artery grafts in one hundred and twenty consecutive patients: indications, operative technique, 6 months postoperative functional and angiographic controls.

In the hope of establishing the internal mammary artery (IMA) as a true but superior substitute for the saphenous vein (SV) we reviewed our initial experience in complex IMA grafting. The first 120 consecutive patients, having received at least one sequential IMA graft were analyzed. The length of the IMA pedicle was the only limitation imposed on its use. Technical artifices enhancing the versatility of the IMA are described. The significant peri-operative myocardial infarction rate was 3.3%. There was no cardiac operative mortality, and 1 late mortality (0.8%). Excellent functional results were illustrated by a 2.5% rate of residual angina and dyspnoea. Six months postoperative angiographic controls could be performed in 70% of the patients: all of the sequential mammary conduits were patent, as were 95% of the anastomoses. By contrast 87.2% of the concomitant venous anastomoses were still functioning. With the expanding utilization of the free graft, IMA is expected to become a true, better and all round substitute for the saphenous vein.

[False reactions in hydatic serology in order to improve its value (author's transl)].

We have studied false reactions in hydatic serology in order to improve its value. We have found false positive reactions in two cases of tumor (hepatic sclerocholangiomatosis and pleural mesothelioma) and among children showing cor's milk protein intolerance when serum is tested with an antigen extracted from ox's lung. As for false negative reactions, they are scarcely due to circulating antigens. We have found, for 34 falsely negative serums, IgG, IgM and above all IgE levels lower than the levels of patients showing a positive serology.

[Clinical study of a population of patients hospitalized for eating disorders. Discussion of DSM III-R diagnostic criteria].

Patients consecutively referred for a clinical diagnosis of eating disorders to the Unit for Addictive Disorders at the University Hospital of Nantes were included in the study. The sample contained 95 patients (94 females, 1 male; mean age +/- SD: 24.1 +/- 6.5). All the patients were evaluated with the Computerized Multiple Diagnostic Instrument for Eating Disorders, which assesses diagnostic criteria for eating disorders from different international diagnostic classifications. Seven (7%) patients fulfilled the DSM III-R criteria for anorexia nervosa (AN) and 42 (44%) the DSM III-R criteria for bulimia nervosa. Two subgroups of bulimic patients were distinguished according to Body Mass Index [anorexia-bulimia (AB) if BMI was < 18 (n = 11, 12%) and normal weight bulimia (NWB) if BMI was > 18 (n = 31, 33%)]. Most patients (n = 46, 48%) did not fulfill DSM III-R criteria for AN or bulimia, and were given the residual DSM III-R diagnosis of eating disorder not otherwise specified (EDNOS). A comparison was made of the frequencies of the different weight control strategies displayed by the patients of the 4 subgroups. Vigorous exercise was more frequently used by AN patients than by patients of the 3 other subgroups. Vomiting was more frequent in bulimic patients, although this symptom was displayed by 29% of the AN patients and 24% of the EDNOS. Abuse of laxatives or diuretics was similar in the four subgroups. Use of diuretics was infrequent in the total sample of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Aminopyrine breath test: development of a 13C-breath test for quantitative assessment of liver function in humans.

BACKGROUND/AIM: 14C-aminopyrine breath test (ABT) has been shown to be well correlated to the severity of liver diseases, but its use is limited in countries where radioactive isotopes are severely controlled. The goal of this study was to develop a 13C-ABT based on a highly sensitive method to measure 13CO2 in breath samples. MATERIALS AND METHODS: The relevant parameters were studied in 26 controls and 27 patients: the 13CO2 enrichment of expired breath between t-10 and t+60 minutes was determined as the most simple and clinically useful parameter. The 13C-ABT was then prospectively compared to clinico-biological data and the galactose elimination capacity (GEC) in 82 patients. RESULTS: The 13C-ABT was well correlated to: i) the Child-Pugh classification; ii) GEC results; iii) the hepatic volume. The presence of ascites or alcoholic consumption did not alter significantly the results of the test. 13C-ABT appeared more sensitive than GEC to evaluate minor liver dysfunctions. CONCLUSIONS: The 13C-ABT is a simple and sensitive test to measure liver function. The use of the stable isotope 13C ensures the harmlessness of the test and the possibility to repeat it in a given patient.
