Thyroidal disorders are found among the most common causes of patients
visits to internal medicine polyclinics. Most of them are probably related with
autoimmune thyroiditis (AT) and/or multinodular goiter (MNG) because micro-nodulation
is a common feature of AT. We have taken 430 consecutive patients applying for
check up procedure to detect prevalences of thyroidal disorder and operations.
Student t-test has been used as the method of statistical analysis. Thirteen
cases had been operated for MNG, one of female operated twice, one for papillary
carcinoma of thyroid and one for Graves disease. So operation rates for
MNG have been 5.26 (12/228) and 0.9% (2/202) among female and males, respectively.
When we compared these rates with the chance of having a thyroid cancer for
either sex, the difference in women has been found as statistically significant
(p<0.01), whereas not in men (p>0.05). Additionally 40 cases with abnormal
thyroid function tests have been detected. Thirty three of them have been diagnosed
as AT (82%) and 85% of the AT cases have been female. As a conclusion, AT and
MNG operations have high prevalences in women and most of the MNG are probably
related with AT. Whereas thyroid cancer is a rare event and it accounts for
rather few deaths. Thus thyroid nodules should be evaluated by experienced physicians
on gland. By this way, high prevalence of MNG operations and their costs and
complications can be reduced in women.
