Acute and chronic corticosteroid treatment of ten patients with paralytic form of Sydenham's chorea.

Aims: To determine efficacy and safety of corticosteroid treatment in patients with severe Sydenham's chorea paralytic form.

Methods: This is a 4 years observational study on ten patient with severe paralytic form of Sydenham's chorea unresponsive to neuroleptics and antiepileptics agents, treated with intravenous methylprednisolone followed by oral deflazacort therapy. Chorea paralytica patients were bedridden, unable to take independent steps, showed severe generalized hypotonia and were hospitalized for 3-4 weeks.

The homozygous ganglioside-induced differentiation-associated protein 1 mutation c.373C > T causes a very early-onset neuropathy: case report and literature review.

Mutations in the ganglioside-induced differentiation-associated protein 1 (GDAP1) gene may cause severe early-onset inherited neuropathies. Here, the authors report a clinical and neurophysiological follow-up of a Pakistani child with a very early-onset neuropathy carrying a novel homozygous mutation in the GDAP1gene. They discuss the relationship between the several forms of Charcot-Marie-Tooth disease presenting in the first months of life and focus on the literature of GDAP1-associated early-onset neuropathy.

Early onset methylmalonic aciduria and homocystinuria cblC type with demyelinating neuropathy.

Methylmalonic aciduria and homocystinuria, cblC type, is the most common inborn error of vitamin B(12) (cobalamin) metabolism. The recent cloning of the disease gene, MMACHC, has permitted genotype-phenotype correlation. In a 1-year-old girl, compound heterozygous c.
