Pediatric Hereditary Neuralgic Amyotrophy
نویسندگان
چکیده
Hereditary neuralgic amyotrophy is a rare disorder characterized by the sudden onset of recurrent episodes of painful brachial plexus neuropathies, followed by atrophy within a few weeks. The authors present the case of a 5-year-old boy who developed hereditary neuralgic amyotrophy in the right upper limb after a gastroenteritis illness. He made a full and rapid recovery with the use of intravenous immunoglobulin. A subsequent episode in the left upper limb during the course of intravenous immunoglobulin was significantly attenuated. A de novo c.262C>T mutation in exon 2 of the SEPT9 gene was identified. To our knowledge, he is the first pediatric patient with SEPT9 hereditary neuralgic amyotrophy to be treated with intravenous immunoglobulin. The authors hypothesize that the c.262C>T mutation in exon 2 of the SEPT9 gene generates pathology via the numerous isoforms under specific conditions and that intravenous immunoglobulin can play a role at the epigenetic level of improving dysfunctional SEPT9 expression.

Hereditary neuralgic amyotrophy associated with a relapsing multifocal sensory neuropathy.
A family with neuralgic amyotrophy (idiopathic brachial plexus neuropathy) associated with a multifocal sensory neuropathy is described. Four members over two generations were affected by neuralgic amyotrophy, inherited as an apparent autosomal dominant trait; two also had a multifocal relapsing sensory neuropathy with the clinical features of Wartenberg's migrant neuropathy.

We report the findings in five muscle and three sural nerve biopsies, and in one postmortem plexus specimen, from six patients with hereditary neuralgic amyotrophy (HNA). We found that the sensory nerves are definitely involved in HNA despite the mainly motor symptoms, and that lesions in nerves and muscles are more widespread throughout the peripheral nervous system than clinically presumed, b...

Neuralgic amyotrophy is a well recognised condition of unknown aetiology with characteristic clinical features.' These include severe pain in the shoulder region, followed within hours or weeks by motor or sensory abnormalities, or both, in the distribution of the cervical roots or nerves. Unilateral disease is more common clinically but if electromyographic (EMG) studies are performed bilatera...
