Introduction: Benefit of general screening for concomitant autoimunne diseases in patients with chronic autoimunne thyroiditis (AIT) is serious problem from medical, even from economic point of view. Some authors advice for screening, some advert to mass occurence of AIT and warn about huge expenses. Situation vary from one country (region) to another.Aim: To assess incidence of celiac disease in patients with chronic autoimunne thyroiditis and find any ...

Familial medullary thyroid carcinoma (FMTC) is an autosomal dominant inherited disease, characterized by germ-line mutations in the RET proto-oncogene, mainly in exons 10 and 11, but also in exons 13, 14 and 15. Recently, there were described also mutations in exon 8 and 16 associated with FMTC. In our laboratory the screening of six risk exons of the RET proto-oncogene in 141 families with MTC was performed. 10 families were classified as clinically FMTC. In 4 of them mutatio...

Introduction: Activating point mutations in the RAS genes (H-RAS, K-RAS, N-RAS) are reported in thyroid tumors. The aim of this study was to determine the frequency of RAS mutations in 98 patients with thyroid tumors.Methods: DNA was extracted from 72 fresh frozen thyroid samples and 26 paraffin-embedded formalin-fixed samples. The cohort contained 83 PTCs (56 FVPTCs, 14 mixed follicular-classical types, 11 classical variants and two other rare variants)...
