[Prevalence of toxoplasmosis in pregnant women of the province of La Habana]. / Prevalencia de infección toxoplásmica en gestantes de la provincia La Habana.

A seroepidemiological study of Toxoplasma gondii was carried out in four municipalities of Havana Province from October 1990 to April 1991 using a 10 microL ultra micro-ELISA. We tested 362 serum samples, from pregnant women, and 71% of toxoplasmic infection was found. Toxoplasmic infection was more frequent in women living in rural zones having domestic contacts with cats. The relationship of toxoplasmic infection and spontaneous abortion antecedent in this group was analyzed but no statistically significant differences were found.

The value of emergency angiography in the diagnosis and prognosis of acute mesenteric arterial insufficiency.

Selective angiography is the technic which provides a higher accuracy in diagnosing an acute mesenteric arterial insufficiency. If carried out at an early stage it surpasses any other technic. It permits not only obtaining topographic data to locate the occlusion but also the detection of aspects of the collateral circulation in the loops of the bowel, thus enabling us to determine the therapeutic procedure to follow. We have done selective angiography of the superior mesenteric artery in nine patients in all of whom we identified the embolic disease. In five of these patients the embolus was in the main trunk and in four it was in the distal branches. The mortality rate varied depending on the site of the embolus and the time elapsed in the process. In three of the patients with distal localization and in one with trunk localization and sufficient arterial permeation, a conservative therapy was used with good results in all of them.
