Johanson-Blizzard Syndrome: Autopsy Findings with Special Emphasis on Hypopituitarism and Review of the Literature
Bibliographic record
Abstract
We present the 1st autopsy findings of a child who had Johanson-Blizzard syndrome (JBS) and hypopituitarism. The patient died of acute bronchopneumonia at the age of 4 years. The autopsy revealed a small undescended pituitary that contained a glial hamartoma and a small rim of adenohypopysial cells, which were minimally reactive immunohistologically only for growth hormone. We review the literature with regard to other cases of JBS and hypopituitarism and pituitary function. The need for evaluating pituitary function in all patients with JBS is stressed. At the time of his death, our patient had no clinical evidence of pancreatic exocrine deficiency, and the histology of the pancreas revealed a normal number of acini; however, the acinar cells had an immature appearance. The microlobules were separated by loose fibrous tissue, and there was extensive periductal fibrosis. The spectrum of the pathognomic feature of congenital pancreatic exocrine insufficiency in JBS is discussed.

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.
