A decrease in blood pressure following pyelolithotomy but not extracorporeal lithotripsy.

Our aim was to evaluate the hypothesis that relief of renal obstruction lowers the arterial blood pressure if the procedure of stone removal does not injure the kidney itself. Sixty patients with unilateral renal stone were evaluated at baseline and 3 months after electrical shockwave lithotripsy (ESWL, n=30) or Gil-Vernet intrasinus pyelolithotomy (n=30). Blood pressures were measured noninvasively and renal vascular resistances were obtained from radionuclide measurements of renal blood flow.

Symptom presentation of acute myocardial infarction: influence of sex, age, and risk factors.

Objectives: The purpose of this study was to examine the symptomatology of onset of acute myocardial infarction (AMI) in patients according to sex, age, and existence of conventional risk factors.

Background: Some studies have suggested that sex and other patient characteristics may influence symptoms in AMI, but data were limited and conflicting.

Methods: This was a prospective, observational study of a large number of symptoms in 1996 patients admitted to Clinical Hospital Split between January 1990 and July 1995 as the result of a first AMI.

Blood gases and sex hormones in women with and without genital descensus.

Background: Abnormalities in connective tissue and spirometric disorders have previously been found in women with genital descensus.

Objective: To evaluate the association of descensus and respiratory function.

Methods: The blood gases and sex hormones were measured in 130 women scheduled for surgical correction of descensus and 60 matched women without descensus.

An increase in micropulmonary red cell mass in hyperlipidaemic patients.

It is known that pulmonary microcirculation rheology is partly affected by plasma levels of lipoproteins, but only a few data are available for humans. Therefore, in a sample of 30 normal volunteers and 90 patients with various types of primary hyperlipoproteinaemia, the plasma levels of total cholesterol (Chol), low density cholesterol (LDL), the high density cholesterol (HDL), triglyceride (Tg) and fibrinogen (Fib) were measured in conjunction with determinations of plasma viscosity (PV) and the pulmonary capillary red cell volume (RCVc). RCVc was estimated from measurements of the vascular component of the single-breath-diffusing lung capacity for carbon monoxide, using our own modification of the Roughton-Forster's method.
