[Epidemiological study on the incidence of chronic lymphocytic thyroiditis in childhood (author's transl)].

An epidemiological survey on the incidence of chronic lymphocytic thyroiditis in childhood was performed in 11,353 apparently healthy school children in Chiba prefecture, Japan. The present study included 9,416 school children (4,401 boys and 5,015 girls, ages 6--18 yrs) in Chiba City and 1,937 children (744 boys and 1,193 girls, ages 16-18 yrs) in Tateyama City. The first group was selected as a representative of urban area, and the second group was selected as that of seaside area. Children having goiter were selected for testing antihyroblobulin and antimicrosomal antibodies in sera. Final diagnosis of chronic lymphocytic thyroiditis was based on histological specimens obtained by needle biopsies on the antithyroid antibody positive subjects. The overall incidence of chronic lymphocytic thyroiditis in these children with 1.7 per 1,000 children. There was a considerable sex difference in the prevalence. None of the patients were boys. In girls the incidence increased with age: ages 6-12 0.9, ages 13-15 4.6 and ages 16-18 3.1-4.2 per 1,000, respectively. The incidence in the seaside area, 2.6 per 1,000 was not significantly higher than that in the urban area, 1.8 per 1,000. Histologically, all cases were classified as focal thyroiditis.

Familial thyroxine-binding globulin deficiency in a patient with congenital hypothyroidism.

A kindred with deficiency of thyroxine binding globulin (TBG) was presented. The propositus, a 1-year old female also had congenital hypothyroidism with ectopic (sublingual) thyroid. Decrease in TBG-binding capacity (TBG) values ranging from 1.2-10.2 mug/100 ml) was detected in the seven relatives on the maternal side. Of these subject 2 were male and 5 female; the males had the lowest binding capacities. But six members of paternal relatives were entirely normal in this respect. The mode of inheritance of the abnormality in this family was compatible with the presumption of Nikolai et al. and Shishiba et al., indicating that the inheritance was an X-linked semi-dominant trait. The kinetics of thyroxine (T4) was investigated in a case of partial TBG deficiency with congenital hypothroidism (propositus). The half-life of T4 was shortened, turnover rate increased, extrathyroidal organic iodine and degradetion rate of T4 decreased compared to normal values.
