Beta-Thalassemia Presenting as an Acute Neurological Complication: A Case Report
Bibliographic record
Abstract
Beta-thalassemia is an inherited defect in the rate of synthesis of one or more beta-globin chains of hemoglobin resulting in anemia, hemolysis and ineffective erythropoeisis. Extramedullary hematopoietic tumors may develop in extreme cases of dyserythropoiesis. Acute neurological complications in patients with beta-thalassemia have been reported in association with cerebral ischemia, spinal cord fractures and compression from extramedullary hematopoietic tumors. However extramedullary hematopeietic tumors in the setting of acute blood loss leading to neurological complications have never been reported. We report this case of a 27-year-old woman with beta-thalassemia who presented with acute neurological deficit during immediate postoperative period of cesarean section associated with significant drop in hemoglobin. The Magnetic Resonance Imaging of the thoracic and lumbosacral spine revealed compressive intra-spinal and para-spinal extra-medullary hematopoietic tissue. Patient’s symptoms improved dramatically with conservative management. doi:10.4021/jmc133w

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.
