Veno-venous bypass in experimental liver transplantation: portal-jugular versus caval-portal-jugular.

This study was undertaken to compare the changes in physiologic variables caused by the use of two different types of pump-assisted veno-venous bypass during experimental liver transplantation. The experiments, performed on female pigs weighing 30 +/- 2 kg, were divided into two groups depending on the bypass used. During the anhepatic phase a pump-assisted portal-jugular (PJ) bypass was used in Group 1 (n = 8) at a flow rate of 15 ml kg-1-min-1, while a pump-assisted caval-portal-jugular (CPJ) bypass was used in Group 2 (n = 8) at a flow rate of 20 ml kg-1-min-1. Intraoperative haemodynamics, pulmonary gas exchange, haematological and serum biochemical parameters were evaluated. Postoperative animal survival rate and complications associated with the bypass used were evaluated. Mean pulmonary artery pressure (Ppa) and pulmonary vascular resistance (Pvr) showed significantly different behaviour in the two groups, whereas the remaining parameters all showed the same trend. Thus an earlier and more substantial increase in Ppa and Pvr values was found in Group 1 when compared to Group 2 during the anhepatic phase. The different behaviour shown by Group 1 may depend on the release of circulating vasoactive substances generated following pelvic venous congestion caused by the temporary clamping of the inferior vena cava. In conclusion, this study indicates that the pump-assisted CPJ bypass is more suitable than the pump-assisted PJ bypass. Furthermore, in order to obtain better results it should be used routinely in porcine liver transplantation.

[Evaluation of the degree of maturation of the cervico-vaginal epithelium in normal, inflammatory and dysendocrine states]. / Sulla valutazione del grado di maturazione dell'epitelio cervico-vaginale negli stati normali, flogistici e disendocrini.

The AA. have determined the maximum percentage of the para-basal cells compatible with a phlogistic state resulting from the exam of 2400 cervical and vaginal smears from women of various ages that were not following therapies able to falsify the evaluations of the endocrine situations. At the objective exam the patients had no sure signs of erosions, thyroid illnesses, vitamin deficiency or cervical metaplasia. The aim of the research was to find a criteria of evaluation of the endocrine situations of the patients, that were not easily influenced by the variations of the karyopyknotic index and acidophilix that are met in the course of numerous illnesses.

[Vulvovaginal candidiasis in pregnancy and its treatment with clotrimazole]. / La candidosi vulvovaginale in gravidanza e il suo trattamento con clotrimazolo.

The Writers have carried out a study on 624 pregnant women pointing out that the incidence of vulvovaginal candidiasis is notably increased (35,5%) during pregnancy with a slight difference in the three three-monthly periods of pregnancy. Controls on 195 women after treatment with clotrimazole showed an average percentage of recovery of 83% with a maximum of 87% in the second three-monthly period.

[Statistical observations on the incidence of Trichomonas vaginalis in the female population of Terni from 1974 to 1978]. / Rilievi statistici sulla frequenza del Trichomonas vaginalis nella popolazione femminile in Terni dal 1974 al 1978.

The casuistics refers to 1646 cases equal to 20,5% of vaginal trichomoniasis in a total of 7996 pap tests examined in the service of Anatomy and Histology Pathology in the hospital of Terni. The exams of the incidences of trichomoniasis in the various age classes, reveals that the main frequency is found in the 2nd., 3rd., 4th decades of life, that is in the period of maximum sexual attivity. Vaginal Trichomonas is rarer before puberty and after the menopause.

[Association between Trichomonas vaginalis and some types of lesions of the uterine neck based on data collected in the quinquennium of 1974--1978]. / Considerazioni sull'associazione tra il Trichomonas vaginalis e alcuni tipi di lesione del collo uterino in base ai dati raccolti nel quinguennio 1974--1978.

In our statistic the number of cases of vaginal trichomoniasi in which discariosi, displasie, metaplasie are found are represented in about 40%. While 37,5% of women affected with neoplastic lesions had Trichomonas vaginalis. It is certain that in the presence of flogosi from Trichomonas vaginalis we meet more frequently than normal, atipie cellulars and that often an exact valutation of this lesion is put back to an exam after the recovery of the Trichomonas vaginalis, because fortunately, more than often these disturbances disappear.
