Frequency of Hashimoto's thyroiditis in children with type 1 diabetes mellitus.

A total of 1419 children with type 1 diabetes mellitus was investigated in order to assess the true frequency of Hashimoto's thyroiditis (HT), diagnosed by microsomal and/or thyroglobulin autoantibodies, by ultrasound and in many cases also by fine needle biopsy. According to these criteria, 55 cases (3.9%) of HT were identified, a number significantly higher (P < 0.

Bone mineral density in children and adolescent females treated with high doses of L-thyroxine.

Single-photon absorptiometry was used to assess forearm bone mineral content (BMC) at a proximal site (PBMC) and at a more distal site (DBMC) of the non-dominant distal forearm in 20 children and adolescent females taking high doses of L-thyroxine (120 micrograms/m2/day) for a period of 6-96 months for endemic goiter, Hashimoto's thyroiditis or thyroid cancer. PBMC was significantly reduced compared to controls (p < 0.002).

Isolated dehydroepiandrosterone sulphate hypersecretion: a case report.

The case of a 17-year-old male with isolated hypersecretion of dehydroepiandrosterone sulphate (DHEAS) is described. Cushing syndrome, congenital adrenal hyperplasia due to 3 beta-hydroxysteroid dehydrogenase deficiency, an androgen producing adrenal tumour, and elevated plasma DHEAS due to an increased renal threshold were excluded. Selective renal vein catheterization confirmed bilateral, isolated adrenal DHEAS hypersecretion.
