Hemophilia C: A Case Report With Updates on Diagnosis and Management of a Rare Bleeding Disorder
Bibliographic record
Abstract
Hemophilia C or factor XI deficiency is a rare clotting disorder with prevalence of only 1 per 1 million. A 24-year-old male with multiple abdominal surgeries complicated by wound infections and poor healing was admitted to plastic surgery service for an elective abdominoplasty. Hematology was consulted for increased intraoperative and postoperative bleeding. Laboratory workup showed high-normal activated plasma thromboplastin time of 31 s (reference: 23 - 34 s), prothrombin time (PT) of 15 s (reference: 11.8 - 14.3 s) and internationalized normal ratio (INR) of 1.2. Patient had normal factors VIII, IX, XIII levels and normal von Willebrand's factor level. The factor XI level came back at 0.28 (0.44 - 1.43 U/mL) diagnostic for intermediate factor XI deficiency. Factor XI is responsible for thrombin generation after clotting is initiated as well as clot stabilization. The confirmatory test is factor XI assay. The management of factor-XI deficiency is based on history of bleeding and nature of the procedure.

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.
