[Diagnostic value of the Doppler ultrasound of kidney vessels in pregnancy complicated with preeclampsia].

Preeclampsia (PE) is a complication of the second half of the pregnancy whose clinical course is hypertension and proteinuria with or without edema. Its pathogenesis is characterized with generalized vasoconstriction and endothelial dysfunction. The aim of this study is to evaluate the diagnostic value of the Doppler ultrasound examination of the renal interlobar vessels in pregnancy complicated with preeclampsia in the context of the theory of the increased vessel resistance in this pregnancy disorder.

[Lipid metabolism and its changes in pregnancy].

A survey is made on physiology of lipid metabolism and its variations during pregnancy. The mechanisms leading to an increase in triglycerides and cholesterol during pregnancy are explained. These changes induce increased aterogenic risk, higher risk for developing pathologic 1 changes in blood vessels on microcirculation level on the basis of endothelial disfunction.

Clinical significance of antinuclear antibodies, anti-neutrophil cytoplasmic antibodies and anticardiolipin antibodies in heroin abusers.

Background: Different autoantibodies and immunologic abnormalities have been described in heroin abusers positive for human immunodeficiency virus, hepatitis B surface antigen, or hepatitis C virus, as well as in addicts with negative viral markers.

Objectives: To investigate the prevalence of different autoantibodies in heroin addicts.

Methods: We studied 10 heroin addicts (8 males and 2 females aged 18-30 years) with a mean duration of heroin abuse of 46.

[Acute renal insufficiency during pregnancy with acute pancreatitis].

According to current data the incidence of acute pancreatitis is from 1:1000 to 1:5000. Symptoms vary a lot, one of rare but most severe complications being acute renal failure. The case is a 24-year-old pregnant patients--30-th gestational week with symptoms of acute pancreatitis based most probably on hereditary hypertriglyceridemia and hypercholesterolemia.
