Compound heterozygous congenital protein C deficiency: a challenging management with recurrent purpura fulminans treated with protein C concentrations
Bibliographic record
Abstract
A female newborn was transferred to the hospital due to progressive necrotic skin lesions. She was born full-term with an average birth weight and no prenatal or perinatal problems. She developed the first purplish skin lesion on her left buttock since postnatal day 1. She was initially treated with antibiotics under the impression of early-onset neonatal sepsis; however, her lesions worsened and rapidly progressed. The protein C chromogenic activity was remarkably decreased at below 10%, similar to a protein C antigen level below 1%, highly suggestive of severe congenital protein C deficiency. Molecular analysis revealed compound heterozygous likely pathogenic variants in the protein C gene. After the diagnosis, fresh frozen plasma (FFP) transfusions every 8 hours until the patient was stabilized and therapeutic low-molecular-weight heparin was started. She developed complications related to FFP administration, such as acute kidney injury, hypertension and proteinuria, during the interim period, awaiting the initiation of protein C concentrate replacement therapy.

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.
