Comparison of some different methods for analysis of thyroid autoantibodies: importance of thyroglobulin autoantibodies.

Blood samples from 141 children and adolescents were used to evaluate differences between commercial kits and radioimmunoassay (RIA) methods for detecting thyroid autoantibodies. Thyroglobulin autoantibodies (Tg-Ab) were analyzed with a hemagglutination kit and a RIA; thyroid peroxidase autoantibodies (TPO-Ab) were measured with a gelagglutination assay and a RIA. The results of the antibody tests were compared with thyroid function tests (triiodothyronine [T3], thyroxine [T4], thyrotropin [TSH]) and with the results of ultrasound of the thyroid in antibody-positive patients.

The coexistence of thyroid autoimmunity in children and adolescents with various allergic diseases.

The aim of our study was to investigate the coexistence of thyroid autoimmunity and allergic diseases. The prevalence of thyroid autoantibodies was studied in sera from 140 children with different kinds of allergic diseases, 370 11-13-y-old schoolchildren without allergic diseases serving as controls. The prevalence of thyroid peroxidase autoantibodies was found to be higher among the patients than in the control group, 11.

A comparison of terbutaline inhaled by Turbuhaler and by a chlorofluorocarbon (CFC) inhaler in children with exercise-induced asthma.

The present study compared the bronchodilating effect of inhalation from the Turbuhaler (0.5 mg terbutaline x 2) with the effect of inhalation from the chlorofluorocarbon (CFC) inhaler (0.25 mg terbutaline x 4) in children aged 9-17 years with reproducible, exercise-induced asthma (EIA).
