Endocrine abnormalities in cardiofaciocutaneous syndrome: a case of precocious puberty, hyperprolactinemia and diabetes insipidus
Bibliographic record
Abstract
A 7-year-8-month-old boy with cardiofaciocutaneous syndrome caused by the D638E mutation of the B-Raf proto-oncogene (BRAF) presented with new-onset seizures. He was incidentally found to have advanced Tanner staging on physical examination. Hormonal testing revealed pubertal levels of gonadotropins and sex steroid hormones. On brain imaging, a lack of visualisation of the posterior pituitary bright spot was observed, in addition to mild thinning of the corpus callosum and the lateral gyri of the cerebellar hemispheres. A diagnosis of idiopathic central precocious puberty was made and the patient was started on leuprolide depot treatment. Pituitary hormone testing revealed hyperprolactinemia for which the patient did not receive treatment as he was asymptomatic. During a subsequent hospital admission for seizures, the patient was diagnosed with transient central diabetes insipidus for which he required treatment with a desmopressin infusion.

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.
