[Analysis of present diagnostic methods of intrapartum fetal hypoxia].

Objective: To evaluate specificity of present diagnostic methods of intrapartal fetal hypoxia (cardiotocography--CTG, fetal pulse oxymetry--FpO2, ST-ECG analysis).

Design: A prospective study.

Setting: Gynecology-Obstetrics Clinic, 1st Medical Faculty and General Faculty Hospital in Prague.

Does a relationship exist between ioduria, magnesiuria and calciuria?

We investigated the mutual relations between ioduria in the one hand, and calciuria, magnesiuria, and creatininuria, on the other hand in a randomly selected group of the population of the Czech Republic. The individual parameters were always determined in the sample of monitoring urine after night fasting, concentration according to the WHO/ICCIDD, we observed a parallel increase of calciuria, magnesiuria and creatininuria. The values of calciuria, magnesiuria and creatininuria correlated positively with ioduria both in children and in adults aged 6-93 years without any statistical effect of sex.

Status of magnesium, selenium and iodine saturation in the population of seven regions in the Czech Republic.

In seven regions of the Czech Republic the magnesiuria and calciuria were determined photometrically using the apparatus Merck Vitalab Eclipse, the selenuria fluorimetrically and the ioduria photometrically after alkaline mineralization in the morning sample of urine (after night fasting) in subjects aged 6-65 years (3,587 probands) selected at random. The lowest magnesiuria was found in children in Klatovy district (5.36 nmol/l +/- 0.

[The effect of age on levels of magnesium and creatinine in the urine].

Background: The concentration of magnesium in urine reflects its intake from food resources. The main regulatory mechanism of magnesium homeostasis is the kidney filtration-absorption process. So far the reference values are not known of the magnesium concentration in urine in dependence on age and sex for the normal population.

[Ultrasound densitometry of the heel bone in a random sample of the adult Czech population].

To assess the state of the skeleton of 870 subjects selected at random the authors used ultrasound densitometry of the talus. The assessment was made using a Cuba Clinical apparatus (McCue Ultrasonic Ltd.UK).
