[Hysteroscopy as a diagnostic method in postmenopausal metrorrhagia]. / L'isteroscopia come metodica diagnostica nelle metrorragie della post-menopausa.

We performed 215 hysteroscopies for post-menopausal bleeding. The most common abnormalities found were endometrial hypoatrophy and low-risk hyperplasia, the less common high-risk hyperplasia and adenocarcinoma of the endometrium. The correlation between hysteroscopic view and endometrial sampling was always very high. Hysteroscopy seems to be a very accurate method for evaluating patients with post-menopausal bleeding especially if associated with endometrial sampling.

[Pregnancy and delivery after 40 years of age]. / La gravidanza ed il parto dopo i 40 anni.

BACKGROUND: In order to study the risks involved with advanced maternal age, pregnancy and delivery of all the women after forty (n = 551) who attended the Obstetrical and Gynecological Clinic of the Palermo University from January 1, 1981 to December 31, 1990 have been examined. MATERIALS AND METHODS: A control group, consisting of women aged 21 to 26 (n = 7980) who attended the Clinic during the same time period, was used for comparison. Each group was analysed for the following parameters: pregnancy complications, time and outcome of deliveries, rate and indications for cesarean section, neonatal outcomes. RESULTS AND CONCLUSIONS: The results show no significant differences in the factors analysed between the two groups observed, except for an increased rate of abortions and Cesarean sections in the study group and an increased rate of premature rupture of membranes in the control group.

[Pancreatic function after subdiaphragmatic vagotomy]. / La funzione pancreatica dopo intervento di vagotomia sottodiaframmatica

After brief mention of certain aspects of pancreatic secretion and having stressed the importance of nervous and humoral regulator systems, the results of a study of pancreatic secretion function in vagotomized patients are reported. It was shown that the majority of distribances occur at an early stage and tend to reduce as time goes on as a result of the compensation mechanisms which gradually set in. A small percentage of vagotomized patients remains, however, in whom slight disturbances continue. These are not enough to constitute a contraindication to the use of vagotomy as an alternative technique in the surgical treatment of gastroduodenal ulcer.

[Experimental evaluation of mesenteric flowmetric changes induced by eating and digestion under normal conditions and after vagotomy and gastric resection]. / Valutazione sperimentale delle modificazioni flussimetriche mesenteriche determinate dal pasto e dalla digestione in condizioni normali e dopo intervento di vagotomia o di resezione gastrica

Reference is made to recent data concerning the regulation of mesenteric haemodynamics by enteric hormones. Changes in mesenteric circulation in the course of altered intestinal hormonal secretion were examined. The results showed that a real connection exists between such secretion and the regulation of mesenteric haemodynamics, since flowmeter changes were noted after surgical operations performed on experimental animals.

[Flowmetric changes induced by glucagon in the mesenteric artery region during experimental hemorrhagic shock in dogs]. / Modificazioni flussimetriche indotte dal glucagone nel distretto arterioso mesenterico in corso di shock emorragico sperimentale nel cane

The pharmacological action of glucagon in the regulation of systemic and mesenteric district haemodynamics, in line with the approach that has come to the fore in recent years for treating haemorrhagic shock with vasodilators, suggested a study of the effects of glucagon on mesenteric haemodynamics during haemorhagic shock in dogs. It was shown that the infusion of glucagon increases mesenteric arterial flow and peripheral resistances are reduced without particular systemic modifications.

[Flowmeter changes induced by glucagon in hepato-portal hemodynamics in the course of hemorrhagic shock in dogs]. / Modificazioni flussimetriche indotte dal glucagone nell'emodinamica epato-portale in corso di shock emorragico nel cane

Anoxic lesion in haemorrhagic shock may result in exclusion of the capillary circulation to the point of stagnant hypoxia. Under normal conditions, glucagon regulates hepatoportal haemodynamics. Its experimentation in the correction of haemorrhagic shock in the dog showed that it increased hepatoportal flow towards normality by reducing local resistance. The consequences with respect to intestinal tissue metabolism make this finding of particular interest.

Mycoplasmas in pregnant women and in newborn infants.

Mycoplasmas were isolated from 96 of 143 vaginal swabs of pregnant women on their first visit at the Prenatal Center. Ureaplasmas alone were isolated in a higher percentage than M. hominis alone or combination with Ureaplasmas. The isolated cultures at 36 weeks of gestation show no significant difference with the first visit isolation. Colonization of mycoplasmas were found in a higher percentage (93.3%) in the abnormal deliveries than in normal ones. Mycoplasmas were isolated also from throat swabs of 19 out of 141 newborn infants: the proportion of mycoplasmas positive infants was higher in low birth, weight children.
