[Use of a new long acting local anesthetic, etidocaine in anesthesia-resuscitation (Duranest)].

Our experiment covered 123 patients who were given this new preparation with long action for various types of local and regional anesthesia. In 9 cases of peridural administration for several days, the total doses were very high and tolerance excellent. Results were good for all local and regional anesthesia for which this product was used: - Good local and general tolerance - Short latency period - Duration constantly and regularly prolonged: an average of 3 hours for non-adrenalin forms and 5 hours for adrenalin forms.

[Surgically curable hypertension (author's transl)].

A case of hypertension was cured by simultaneous surgical treatment of an obstructive urolithiasis associated with a pheochromocytoma. Primary devascularization of the adrenal tumor, reducing blood pressure and cardiac rhythm variations was allowed by preoperative arteriography.

Comparison of four fixatives for routine splenic histology and immunohistochemical staining for group II avian adenovirus.

Four different fixatives, A, B, C, and D, were compared for use in routine histology of splenic tissue and for immunohistochemical staining to detect group II avian adenoviral antigen. Sixteen pheasants were experimentally infected with type II adenovirus; spleens from each bird were harvested, divided, and treated with each of the four fixatives. All four fixatives were adequate for routine histology. Fixative B was significantly more sensitive for immunohistochemistry than the three other fixatives, and it also detected the viral antigens at the highest dilutions of the primary antibody.

[Pseudomembranous colitis caused by antibiotic therapy. Results of a survey of the patient material from the praxis of 900 gastroenterologists].

A retrospective study conducted by interviewing French gastroenterologists was performed with the objective of evaluating the incidence and etiology of pseudomembranous colitis in cases where the diagnosis has been confirmed by coloscopy. This study allowed to collect data on 878 pseudomembranous colitis observed by 438 gastroenterologists within 6 months. It shows evidence of the importance of various antibiotics in the etiology of pseudomembranous colitis (89% of the identified cases). The following is the list of antibiotics or antibiotic classes, in increasing order of their association with the development of pseudomembranous colitis: macrolides which are very rarely associated, a group represented by cefaclor, cefuroxime axetil and cyclins, which are rarely associated, a third group constituted by amoxicillin, ofloxacin and trimethoprim-sulfamethoxazole which appears to be 2 to 3 times more frequently associated than the previous group, and a fourth group of antibiotics, represented by cefixime and the association amoxicillin-clavulanic acid, which is 7 times more frequently associated than antibiotics of the second group.

[Quality of life and migraine. Validation of the QVM questionnaire in hospital consultation and in general medicine].

The feasibility, the validity and reliability of the questionnaire "Qualité de Vie et Migraine" (QVM) were assessed during a study performed on 107 patients recruited either in neurological departments in hospitals (N = 58) or by G.P. (N = 49). The study was designed as a Test-Retest, the self-questionnaire being filled twice at an interval of one week. The filling-in time was an average 7 min in hospital and 11 min for G.P.'s patients. The missing values were quite rare, between 1% and 2%. The items were assessed "very interesting" or "interesting" by 94% of the patients, and "easy" or "fairly easy to understand" by 96%. The principal component analysis performed on the whole sample allowed the extraction of 4 meaningful factors which were in agreement with the pre-defined structure of the questionnaire QVM. The 1st axis was a factor of psychological repercussion, the 2nd axis was a factor of functional and somatic repercussion, the 3rd axis was a factor of social repercussion and the 4th one was a factor of disturbance generated by the treatment. The QVM questionnaire allowed the calculation of a global index of quality of life and indexes according to the multifactorial structure. The global index was significantly higher for the most severe patients recruited in hospital, which means that the repercussion of migraine on quality of life was greater than for G.P.'s patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Variations in response of four lines of ring-necked pheasants to infection with marble spleen disease virus.

This study evaluated the response and susceptibility of four lines of ring-necked pheasants to infection with marble spleen disease (MSD) virus. Fifteen birds of the following lines were used: the standard ring-necked gamebird, the highly inbred jumbo white, the Sichuan, and the first-generation cross of the Sichuan and the standard gamebird. Baseline immune responses were assessed at 6 weeks of age by lymphoblastogenesis assays. All birds were orally challenged at 7 weeks of age with cell -culture-propagated MSD virus. Eight birds of each group were necropsied at 6-7 days post-inoculation (PI), and gross splenic lesions were recorded. Appropriate tissue sections were collected, fixed in 10% buffered formalin, and routinely processed for microscopic evaluation. The remaining birds were bled weekly from week 2 through week 8 Pl. Serum was tested for antibodies to MSD virus using a commercial enzyme-linked immunosorbent assay kit. Results of the lymphoblastogenesis assays and the gross and microscopic lesion incidences indicated that variations did exist between several lines evaluated. The jumbo white pheasant had significantly higher lymphoblastogenesis stimulation index and was more resistant to developing gross and histologic lesions than was the standard ring-necked gamebird.

[Transverse laparotomy by supre-pubic detachment of the recti muscles in gynecologic surgery. Apropos of 266 cases].

The authors have studied 266 case histories where supra-pubic detachment of rectus muscles was used according to Cherny's method. This allowed aseptic gynaecological surgery to be carried out in all its forms by a true transverse incision. The advantages are great : it is aesthetic and the incision can be enlarged if necessary indefinitely. This means that surgery can be carried out easily and explains the great rarity of intra-abdominal complications. On the other hand two relatively rare complications do occur with this incision : peritoneal haematomata and lateral herniations. Details have been given of the methods necessary to avoid these complications.
