[The effect of estrogens in the etiopathogenesis of endometrial adenocarcinoma].

Recent data suggesting that oestrogens also encourage the onset of adenocarcinoma of the endometrium in man are reviewed. Emphasis is placed on the fact that this is most likely to occur when prolonged oestrogeni stimulation is not suitably opposed by progesterone. It is felt that the latter, or its synthetic homologues, should be employed in all long-standing cases of exogenous or endogenous hyperoestrogenism.

[Cardiac rhythm disorder in infection caused by cytomegalovirus in patients with kidney transplant].

A higher incidence of arrhythmias was observed in 16 renal allograft recipients infected with Cytomegalovirus (CMV), as compared to 26 patients who were transplanted during the same period and did not contract the infection (43.7% vs. 3.8%; p less than 0.01). There was a highly significant difference in the incidence of sinus tachycardia (37.5% infected vs. 0% not infected; p less than 0.005), while the incidences of atrial fibrillation and ventricular ectopic beats were not significantly different. The arrhythmias always appeared in the early phases of the infection and disappeared after a certain period, lasting from one week to months. It is proposed that arrhythmias arising during CMV infection may be due to a myocardial CMV involvement.

[Dynamics of food transit in gastrectomized patients with and without dumping syndrome studied with the gamma camera and a marked meal].

Scintigraphy was performed on a group of patients following the administration of a solid radiolabelled meal. As a tracer, human albumin microspheres were used with 99mTc, mixed with fresh scrambled eggs, eaten as a sandwich in two slices of white bread. The analysis of transit and emptying-rate of the radiolabelled meal in the gastric or derivative loop areas was performed by means of a medium field (300 mm) gamma camera interfaced with a digital computer; the data were collected at 15" frames for 90'-120'. Twenty-nine patients were examined who had undergone sub-total gastrectomy: 11 of them were "dumpers" and 18 "non-dumpers"; moreover, 9 volunteers without any history of gastrointestinal diseases and 11 patients with different gastric disorders were checked. In the first group of gastrectomized patients the half-emptying time (T50) was significantly shorter than in the 11 people being checked (Md = 27.5 +/- 10.8 versus 69.6 +/- 19 minutes); in "non-dumpers" T50 was even shorter (Md = 24.2 +/- 13 min). There was no significant statistical difference between the two classes of gastroresected patients in both T50 and emptying-rate of the radioactive solid food, which excludes the accelerated transit as a factor in the functional post-prandial symptoms of the dumping syndrome. On the contrary, the dynamic selective analysis of the radiolabelled food transit through derivative afferent and efferent loops showed different patterns in the two groups of gastroresected patients: the progression of the propulsive wave was very irregular and constantly hyperperistaltic only in the dumpers.
