ACTA ENDOCRINOLOGICA (BUC)

Background. Polycystic thyroid disease (PCTD) is a recently defined entity, and its clinical significance has yet to be clarified in children. We aimed to investigate clinical and laboratory associations of PCTD. Methods. This study included 72 consecutive children diagnosed with PCTD. Auxological measurements, additional clinical diagnoses, ultrasonographic results as thyroid volumes, associated parenchymal diseases and solid nodules, serum thyroid hormone, and autoantibody levels, along with urinary iodine levels, were recorded. Results. Thirty-two male (mean age: 8.10±4.99 years) and 40 female (mean age: 9.51±4.68 years) patients were evaluated. No significant difference was found among the mean ages of gender groups (p= 0.22). Mean total thyroid volume was 5.49±4.1 mL and the mean colloidal cyst diameter was 4.36±2.34 mm among all participants. Colloidal cysts were found commonly in both thyroid lobes (90.5%). Solid nodules were found in 11% of the patients without a depicted malignant one. Initial thyrotropin (TSH) values were elevated in 29% (mean:10.89±4.66 mIU/L) of the patients, and initial free thyroxine (fT4) levels were normal in all participants. 31.9% of the patients underwent thyroid hormone replacement therapy with a mean L-T4 dosage of 20.01±9.02 μg/day during the follow-up. Conclusion. PCTD is an increasingly recognized radiological entity that frequently correlates with subclinical hypothyroidism in the pediatric population.

Background and aims. There are numerous intrinsic and extrinsic factors associated with the pathophysiology of rosacea, including immune dysregulation. The aim of this study is to determine the relationship between rosacea and thyroid autoimmunity. Methods. Seventy-two patients with rosacea and 62 rosacea-free control subjects were included in the study. Serum free triiodothyronine (fT3), free thyroxine (fT4), thyrotropin releasing hormone (TSH), antithyroidperoxidase antibody (ATPO), antithyroglobulin (anti-Tg), prolactin, dehydroepiandrosterone sulfate (DHEAS), basal cortisol, serum CRP concentrations and erythrocyte sedimentation rate were measured. Results. The number of the cases with high levels of CRP, anti-M and prolactin in rosacea group were significantly higher than the controls (p<0.05), there was no significant difference according to other parameters in both groups (p>0.05). There was no significant difference according to the presence of a thyroid disease in both groups (p>0.05). The decrease in the CRP parameter in patients with the disease duration of 1-5 years was found to be statistically significant (βCRP=-0.251, pCRP<0.05). There was no statistically significant difference according to disease severity or disease duration (p>0.05). Conclusions. Rosacea may be associated with high thyroid autoantibodies, prolactin and CRP levels, in which immune-endocrine interactions are important.
