The iodine is indispensable element for life that is also fundamental substract for thyroid hormone synthesis which make very important influence on protein's lipid's, carbohydrate's and highly caloric substances metabolism and are a requisite of proper man development. The pregnant women are one of population group which is the most sensitive on iodine's deficiency. The results of researches indicate on insufficient iodine intake in pregnant women diet, whose take food even according to diet's recommendation given by physician. The wide iodine's prophylaxis which was provided as yet is insufficient in case of pregnant and nursing women. It is confirmed the necessity of additional iodine supplementation. A set of control tests should be done in requires cases that inform physician about changes in function and size of thyroid gland and make possible the individualization of treatment. The supplementation doses of iodine about 150 micrograms are safe and there was not observed any side effects during their taking.

[Delivery in adolescence]. / Poród u mlodocianych.

We analysed structure of age within 16,602 deliveries between 1947 and 1977 and data collected from 17,056 deliveries between 1989 and 1992 in Institute of Obstetrics and Gynaecology in Poznan. Percent of women under age 18 deliveries increased from 0.58% in 1947 to 1.3% in the last years. We observed a significant difference in group of teenage mothers: the higher risk of prematurity, lower average birth weight of neonates, lower frequency of cesarean section and higher frequency of surgical assisted vaginal deliveries. There was no significant differences in the frequency of birth weight under 2500 g.

Reduced erythropoietin levels as a cause of anaemia in patients with lung cancer.

Measurements of erythropoietin (Ep) levels in patients with the anaemia of chronic disorders due to malignant disease have given variable results. This variation may be due to the wide range of malignancies studied and the assay method (whole animal) used. In this study Ep levels were measured, using the foetal mouse liver assay, in 39 patients with lung cancer and 19 controls. Twelve patients had reduced haemoglobin levels (Hb less than 11.5 g/dl for males and 11 g/dl for females) and the features of the anaemia of chronic disorders. Their mean Ep level was 0.21 iu/ml. This was significantly lower than for the normal controls, whose mean value was 0.31 iu/ml (P less than 0.02). This data supports the concept that lack of an appropriate Ep response to anaemia is one factor in the genesis of anaemia in malignancy.
