[The role of prophylactic examinations in detecting thyroid disorders. Preliminary results]

Nonpalpable nodules in the thyroid are frequent and estimated to be found in 50% of people above 50 year of age when goiter in adult population is found in 4-10%. Thyroid nodules in 5% are of neoplastic character and their diligent investigation is necessary with USG, FNA and certain biochemical factors evaluation. Screening is an important part of diagnosing thyroid gland.

Prophylactic examination donated by Krakow's City Government was performed in 140 persons aged 18-71 among whom 93.3% were women. Clinical examination, USG, FNA (when it was necessary), and TSH serum level evaluation were conducted in these patients.

In 42.2% (group I) no abnormalities were detected. In 28.5% (group II) USG revealed thyroid nodules when clinical examination was negative. In 29.3% (group III) the presence of palpable nodules was confirmed by USG. In consecutive groups I-III following factors were presented: mean age, frequency of performed FNA's and thyroids volume.

USG is an efficient method in prophylaxis of thyroid disorders.
