Long-term outcome of differentiated thyroid cancer in children and young adults: risk stratification by ATA criteria and assessment of pre-ablation stimulated thyroglobulin as predictors of disease persistence.

Purpose: Differentiated thyroid cancer (DTC) has an increasing incidence in childhood and adolescence but long-term outcome data are limited. We aimed to identify possible risk factors associated with disease persistence, with special focus on the usefulness of ATA risk stratification system and pre-ablation stimulated thyroglobulin (Tg) levels.

Methods: We retrospectively studied 103 patients, 79 females (76.

Unfavorable Hormonal and Psychologic Profile in Adult Women with a History of Premature Adrenarche and Pubarche, Compared to Women with Polycystic Ovary Syndrome.

If circulating adrenal androgens levels rise before the age of 8 years in girls, this phenomenon is termed premature adrenarche (PA), while the concomitant appearance of pubic hair is called premature pubarche (PP). Girls with PA-PP display an unfavorable hormonal profile compared to their normal peers and have an increased risk of developing polycystic ovary syndrome (PCOS) features peripubertally. However, the sequelae of premature adrenarche remains unclear.

Gender, age, puberty, and BMI related changes of TSH and thyroid hormones in schoolchildren living in a long-standing iodine replete area.

The aim of the work was to assess thyroid function in children and adolescents in an iodine replete area and to explore possible effects of age, gender, puberty, and adiposity. Thyrotropin (TSH), total triiodothyronine (T (3)), total thyroxine (T (4)), free thyroxine (FT (4)), and the T (4)/T (3) ratio were determined for 440 schoolchildren (200 boys and 240 girls), aged 5-18 years, living in an iodine replete region. Body Mass Index (BMI), BMI standard deviation score (BMI-SDS), and Body Surface Area (BSA) were calculated.

Thyroid autoimmunity in schoolchildren in an area with long-standing iodine sufficiency: correlation with gender, pubertal stage, and maternal thyroid autoimmunity.

Background: A strong genetic background and gender are believed to be involved in thyroid autoimmunity (TA). The age these factors become manifest is less clear, however. The objective of the present study was to determine the prevalence of TA in children and adolescents and to determine if there are relationships between the period of onset of TA and gender and between TA and maternal autoimmunity.
