Treatment with Methimazole in a 3-Year-Old Male with Thyroid Hormone Resistance
Bibliographic record
Abstract
BACKGROUND: Thyroid hormone resistance syndromes are disorders in which there is decreased end-organ responsiveness to thyroid hormone. Patients typically present with elevated levels of thyroxine and triiodothyronine with a normal or increased serum thyroid-stimulating hormone concentration. Clinical features are variable, and there are no guidelines regarding treatment. PATIENT: The patient was noted to have tachycardia at 6 months of age. He had persistently elevated free thyroxine and normal/mildly elevated thyroid-stimulating hormone for the first 2 years of life. At age 2 years, he was noted to have sinus tachycardia, a mildly enlarged thyroid, hyperactive behavior, subtle developmental delay, and poor weight gain. The patient has a previously described de novo mutation in the thyroid hormone receptor-β gene. INTERVENTION AND OUTCOMES: He was started on methimazole (0.3-0.5 mg/kg/day) at age 3 years to treat his symptoms. With medication, weight gain, sleep, behavior, and tachycardia improved. Linear growth has remained appropriate for age. Heart rate is in the upper normal range and his thyroid has become more enlarged. CONCLUSIONS: Methimazole has improved thyrotoxic symptoms in a 3-year-old male with thyroid hormone resistance. The use of methimazole should be considered in certain patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
