title: Infantile tremor syndrome: Role of Vitamin B12 revisited.
abstract: OBJECTIVE
  To study the role of Vitamin B12 as an etiological factor in patients of infantile tremor syndrome (ITS).
  
  
  METHODS
  Twelve consecutive admissions of children diagnosed clinically as ITS were assessed. Assessment was done using a predefined pro forma to document patient demographic factors, general examination, systemic examination as well as relevant hematological and biochemical investigations.
  
  
  RESULTS
  Out of the 12 cases of ITS, 6 were males and 6 were females. Two cases had serum B12 levels below reference values, five had levels in low normal range, and remaining five had normal values.
  
  
  CONCLUSIONS
  Role of Vitamin B12 deficiency as an etiological factor in the patients of ITS is inconclusive.
