Stuttering priapism in a patient with sickle cell trait treated with automated red cell exchange transfusion
Bibliographic record
Abstract
Sickle cell trait (SCT) is typically an asymptomatic carrier state, but sickling complications can occur under extreme conditions. Priapism is known to be associated with sickle cell disease (SCD); The link with SCT is less well established. We report the case of a 19-year-old man with SCT presenting with prolonged priapism and a refractory, stuttering course requiring multiple invasive procedures over a 5-day period with no clear alternative triggers. In light of ongoing, stuttering priapism, he underwent red blood cell (RBC) exchange transfusion with decrease of hemoglobin S from 45.8% to 11.7%. This was followed by immediate and sustained cessation of stuttering priapism, with no further episodes at 5 months. Multiple cases of priapism associated with SCT have been reported in the literature. In most cases invasive interventions were required but RBC exchange was not attempted. RBC exchange has been reported in 2 people with exertional rhabdomyolysis in the context of SCT, with improvement in 1 case. In patients with SCT and priapism, conservative measures are used to treat brief episodes, but invasive management is required for persistent or prolonged episodes. RBC exchange transfusion may be considered for treatment of refractory, stuttering priapism in individuals with SCT.

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.
