Croatia has reached iodine sufficiency.

This study was performed in 2002, 6 yr after the introduction of a new regulation on salt iodination with 25 mg KI/kg of salt. The aim of the study was to evaluate whether further significant positive results of improved iodine intake could be observed among schoolchildren in Croatia. A total of 927 schoolchildren of both sexes, aged 6-12 yr, were included in the study.

[Endemic goiter in Croatia].

In the early nineties, 40 years after the introduction of iodine prophylaxis in Croatia (10 mg KI/kg salt), a nationwide study was initiated with the aim to determine the real prevalence of goiter in the country. A total of 2436 schoolchildren of both sexes, aged 7-15 years, were included in the study. Investigations were designed in a way to cover most of geographical regions in Croatia and subjects were randomly selected.

Current status of endemic goiter in Croatia: the results of a nationwide study (1995).

In the beginning of the nineties, 40 years after introduction of iodine prophylaxis in Croatia, on a basis of a frequent reports coming from general practitioners about the presence of a rather high prevalence of goiter among schoolchildren, a nationwide study was initiated with the aim to determine the real prevalence of goiter in the country. A total of 2856 schoolchildren of both sexes, aged 7-15 years, were included into the study. Investigations were designed in a way to cover most of geographical regions in Croatia and subjects were randomly selected.

Morphologic diagnosis of Hürthle cell tumors of the thyroid gland.

Despite difficulties in differential diagnosis, aspiration cytology offers unique advantages in the preoperative diagnosis of Hürthle cell (HC) tumors of the thyroid gland over immunocytochemistry and micromorphometry, which have not achieved the anticipated success in the diagnosis of HC tumors. Aspiration cytology is comparable, in terms of speed and accuracy, to microspectrometry of DNA content in HC tumors, a technique that is not convenient for routine use. Detailed morphologic analysis of 19 characteristics of the smears and of the cells revealed five parameters adding to the sensitivity, specificity and reliability of routine diagnosis: HC collection in the form of nests, marked or at least moderate anisocytosis and anisokaryosis, multinucleation and emphasized nucleoli.
