Milk represents an important source of iodine in schoolchildren of the Veneto region, Italy.

The aim of the present study is to evaluate the relationships between urinary iodine concentration (UIC) and the intake of milk and other foods, in a group of school children of the Veneto region, in North East Italy. A questionnaire, concerning the daily intake of milk, yoghurt, cheese and other animal foodstuffs, was distributed to 233 schoolchildren aged between 11 and 15 yr. The use of iodized salt was also investigated.

Normal values for thyroid ultrasonography, goiter prevalence and urinary iodine concentration in schoolchildren of the Veneto Region, Italy.

Goiter prevalence in school-age children and median urinary iodine concentration (UIC) are the main indicators of iodine deficiency in a population. In areas of mild iodine deficiency, where goiters are small, ultrasound is preferable to physical examination to estimate goiter prevalence. The World Health Organization (WHO) has adopted thyroid volume ultrasonography results from a survey of European schoolchildren as an international reference, but these values have recently been questioned.

"Hot" carcinoma of the thyroid. Case reports and comments on the literature.

It seems somewhat difficult to exactly define the real number of case reports concerning the association of hyperfunctioning thyroid node and carcinoma; the overall incidence of this condition seems, however, to be very rare. Different inclusion criteria are probably a fairly relevant cause of variability in the number of cases reported during the years. A basic classification scheme, as the one here reported, may be of help in characterizing the different possible conditions: 1.

Thyroid nodules and Doppler ultrasonography. A new element for an old puzzle?

Background: Whether Doppler ultrasonography (DU) may be of help in characterizing thyroid nodes is still under debate: both good and unsatisfactory results have been claimed, either in evaluating the presence of malignancy or in identifying hyperfunctional structures.

Methods: In this paper, the scintigraphic and Doppler patterns of 80 thyroid nodes have been compared, in the hypothesis that there may be some correlation between functional status and vascularity of the node; a small group of cyto-histological information were considered too.

Results: Perilesional flux seems to be, in general, somewhat more frequent than intranodal or mixed patterns: this is, however, true for all the groups of nodular functional conditions studied (peripheric flux was found in 70.

Appearance of Graves'-like disease following regression of autonomously functioning thyroid nodules. Two case reports.

Two cases are reported in which a rare hyperthyroidism appeared: in a female after radioiodine therapy for toxic multinodular goiter and in a male after spontaneous regression of a toxic adenoma. Both subjects showed a relapse of hyperthyroidism after a period of well-being lasting almost eight months in the first and three years in the second. Thyroid scans were consistent with an immunogenic hyper-thyroidism because there was a diffuse trapping of 131I in the thyroids while the previous autonomously functioning nodules became "cold".
