Key result
Initial classification using diagnostic criteria for acute flaccid myelitis was retained in 7 of 9 definite cases, but many probable (3/11) and possible (3/14) cases had alternative diagnoses.
Why the study?
Differentiation between acute flaccid myelitis and other causes of acute flaccid paralysis can be difficult, particularly at disease onset.
How well do current diagnostic criteria for acute flaccid myelitis perform in differentiating it from other causes of acute flaccid paralysis in children?
Cohort (n=141)
How well do current diagnostic criteria for acute flaccid myelitis perform in differentiating it from other causes of acute flaccid paralysis in children?
Current diagnostic criteria for AFM perform well for definite cases, but additional clinical and diagnostic features are often required to distinguish probable or possible AFM from other conditions like transverse myelitis or Guillain-Barré syndrome.
No takes yet. Share an insight, caveat, or question.
Definite AFM labels show high retention; supports refining criteria for probable/possible cases to better exclude mimics.
Helfferich et al. (2023) conducted a cohort in Acute flaccid paralysis (AFP) / Acute flaccid myelitis (AFM) (n=141). Diagnostic criteria for acute flaccid myelitis vs. Alternative diagnoses was evaluated on Retention of initial AFM classification after expert review and application of alternative diagnostic features. Initial classification using diagnostic criteria for acute flaccid myelitis was retained in 7 of 9 definite cases, but many probable (3/11) and possible (3/14) cases had alternative diagnoses.
