Post-diphtheritic neuropathy: a clinical study in paediatric intensive care unit of a developing country.

A retrospective study was done on 48 consecutive patients with clinical diagnosis of post-diphtheritic neuropathy admitted to the paediatric intensive care unit of tertiary care hospital in North India between January 2008 and December 2010 to study the clinical profile of post-diphtheritic neuropathy in children. The case records were reviewed and information regarding personal details, clinical features, recovery parameters and outcome was recorded using a predesigned proforma. Median age was 4.25 years. All cases were unimmunized. Median latency period was 15 days. Of the children, 52% had palatal palsy whereas 48% had limb weakness initially. Median duration of progression of weakness was five days. Limb muscle weakness was present in 94%. Respiratory muscles were involved in 85.4% cases and 60.4% required mechanical ventilation, while 14.6% had fatal outcome and 10.4% had hypoxic neurological injury. Boys were affected more. Median duration of latency was shorter; muscle weakness, progression and recovery were faster as compared with observational studies in adults.
