...Elizabeth A. Korn; Gregory Gaich; Michael Brines; Thomas O. Carpenter A 13-year-old girl with poor weight gain and pubertal delay was referred for hyperthyroidism. Slightly elevated levels of circulating thyroid hormones failed to suppress circulating thyrotropin (TSH) levels. Despite appropriate...

The plasma levels of these hormones were evaluated after gonadotropin-releasing hormone (GnRH)/thyrotropin-releasing hormone (TRH) stimulation performed after placebo or after 30 mg DHAS i.v. administration. The half-life of DHAS was also calculated on two subjects; two main...
