Pediatric Status Dystonicus: A Single‐Center 10‐Year Retrospective Review
Bibliographic record
Abstract
BACKGROUND: Status dystonicus is a life-threatening movement disorder emergency characterized by frequent or prolonged severe episodes of generalized dystonia. The phenomenology, etiology, and outcome is heterogenous and poorly characterized, making implementation of a standardized management approach challenging. OBJECTIVES: We characterized demographics of children with status dystonicus in a tertiary children's hospital pediatric intensive care unit (PICU), management patterns, and outcomes. METHODS: Clinical records at our PICU were searched via ICD-10 codes, and we also searched the charts of those with severe dystonia known to our clinical service. We included cases admitted to PICU from 2014 to 2024 who had dystonia severity grade 3-5, those with dystonia worse than their baseline, and with age greater than 30 days old, corrected for gestational age. RESULTS: A total of 79 clinical records were screened; 41 admissions from 19 unique patients were included. Mean age was 7.6 ± 4.2 years; 53% were female. Most patients had a genetic etiology (n = 8, 42%). The presenting complaint per admission was often not dystonia (n = 24, 59%); infection was the most common trigger (n = 23, 56%) followed by pain (n = 6, 15%). Patients received several anti-dystonia medications (mean 6.9 ± 2.5), including clonidine, enteral or IV benzodiazepines, IV ketamine, and others. Median PICU stay was 7 days (interquartile range 3-14 days); 37% had multiple PICU admissions. Two patients (4.9%) died from status dystonicus complications. CONCLUSIONS: Status dystonicus is a life-threatening emergency commonly triggered by pain or infection in patients with dystonia. Given the considerable morbidity and mortality, multi-disciplinary teams should consider standardized treatment guidelines for these complex patients.

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.
