Occurrence of Slipped Capital Femoral Epiphysis in Children Undergoing Gonadotropin-Releasing Hormone Agonist Therapy for the Treatment of Central Precocious Puberty
Bibliographic record
Abstract
BACKGROUND: Obesity, age and hormone imbalances including hypothyroidism and growth hormone deficiency and therapy, but not gonadotropin-releasing hormone agonist (GnRHa) therapy, have been identified as risk factors for slipped capital femoral epiphysis (SCFE). Five of 7 reported cases describe SCFE in children shortly after GnRHa therapy cessation. METHODS: We report 3 cases of SCFE that occurred in children on GnRHa therapy for the treatment of central precocious puberty (CPP) and discuss possible promoting factors. RESULTS: An otherwise healthy 8.75-year-old girl [body mass index (BMI) Z score +1.75] developed SCFE 6.75 years into GnRHa therapy for idiopathic CPP. A second girl (with a history of acute lymphoblastic leukemia requiring total body irradiation) was 10.6 years old (BMI Z score +1.06) when she developed SCFE 3.3 years into GnRHa therapy. The third case was an 8.75-year-old female with CPP secondary to a hypothalamic hamartoma (BMI Z score +1.65) who developed bilateral SCFE 5.6 years into therapy. CONCLUSION: Increasing evidence suggests an association between GnRHa therapy for CPP and the occurrence of SCFE. We suggest that a lack of adequate sex hormone exposure at a 'critical period' of bone formation may result in a weakened epiphysis that becomes susceptible to slipping. © 2013 S. Karger AG, Basel.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
