Status Dystonicus in Children with Secondary Dystonia: Reporting 3 Cases of Cerebral Palsy, Leigh Disease and Molybodynum Co Factor Deficiency

Abstract

Objective: Patients with primary and secondary dystonic syndromes occasionally develop severe episodes of generalized dystonia and rigidity which is known as status dystonicus (SD) or dystonic storm. This is a frightening hyperkinetic movement disorder and it is an emergency. Marked,                rapid exacerbation of dystonia requires prompt intervention and admission in the hospital. It is critical to recognize early and differentiate dystonic storm from other hyperkinetic movement disorder as it may lead to metabolic complications such as rhabdomyolysis, leading to acute            renal failure. This paper has been written to describe three cases of SD, all having secondary dystonia with different etiologies to highlight the mode of presentation, diagnosis, treatment and outcome. Methodology: We report 3 cases of severe secondary dystonia culminating in SD necessitating management in hospital setting. All the three cases were admitted in a tertiary care hospital and evaluated. Results: One patient was treated in intensive care unit. In brief 1st case was a 5 year boy with dyskinetic CP who was treated with trihexiphenidyl (THP), baclofen and midazolam infusion. Second case was a 15 month old boy, diagnosed case of mitochondrial encephalopathy (Leigh disease) who was treated with THP, baclofen, haloperidol, clonazepam and infusion midazolam. The third case was a 13 month old boy, diagnosed case of Molybdenum Cofactor deficiency who was treated with THP, tizanidine but they refused to take midazolam. Conclusion: In this case series, three cases with SD with different etiology have been described with clinical features, modalities of treatment and outcome.
