Increased thyroid volume and frequency of thyroid disorders signs in schoolchildren from nitrate polluted area.

Thyroid volume (ThV) and echogenicity by ultrasound were estimated in 324 schoolchildren (aged between 10 and 13-years) from high nitrate area (HNA) located in agricultural lowland with high nitrate drinking water supply (51-274 mg/l) from shallow wells. The data were compared to children of the same age from low nitrate area (LNA) consisting of 168 children from the neighboring area with very low nitrate (< 2 mg/l) drinking water and of 596 children from the city of Kosice located in a vicinity of LNA and also supplied by low nitrate water. Blood samples were obtained from 315 willing children from HNA and 109 children from LNA and the levels of thyrotropin (TSH), total thyroxine (TT4), free triiodothyronine (FT3) and thyroperoxidase antibodies (anti-TPO) in serum were determined.

[Nitrate contaminated drinking water from private wells has an impact on the size and functional state of the thyroid gland in schoolchildren].

Unlabelled: The authors compared the size of the thyroid gland, assessed by ultrasonographic examination of its volume and the functional state of the thyroid by examination of the serum level of TSH and anti-TPO antibodies in 492 pupils aged 10 and 13 years in two close agricultural areas. The areas differed above all as to the nitrate content of drinking water. In communities where the source of drinking water were private wells (nitrate area), as much as 68.

[Therapy of Helicobacter pylori infection using Lactobacillus acidophilus].

Introduction: In vitro experiments with Lactobacillus acidophilus have revealed its inhibitory effect on Helicobacter pylori and its application in treatment of Helicobacter pylori positive gastritis was examined.

Material And Methods: 15 patients have undergone gastroscopy with biopsy and by histopathological examination. Helicobacter pylori positive gastritis was detected.

[Diseases of the upper segment of the gastrointestinal tract and Helicobacter pylori infection].

Helicobacter pylori infection is the most frequent infection in humans. It is assumed that over 50% of total world population suffer from this infection. Chronic gastritis is the most usual consequence of this infection.

[The postoperative status of the gastroduodenum--clinical and endoscopic analysis of 2 years' of hospital data].

In 72 patients operated on for gastric ulcer, hospitalized at the Clinic of Gastroenterology and Hepatology in Novi Sad within two years (1989, 1990) we analyzed clinical disorders, biochemical status and endoscopic findings. 75% of the patients were males and 25% females, mean age being 49 years. In 70.
