Hepatitis E virus (HEV) infection is an emerging disease in developed countries with a broad clinical spectrum. In the absence of immunodeficiency or pregnancy, it is a mild and almost asymptomatic condition in most cases. However, extrahepatic manifestations, including neurological conditions, are common and may occasionally lead to permanent neurological sequelae. Herein, we report the case of an immunocompetent patient who was admitted to our hospital with paresthesia and weakness in both the upper extremities associated with anicteric-elevated transaminases...

I read with interest the work by Drave et al on the replication of hepatitis E virus (HEV) in neuronal cell lines (1). HEV is increasingly associated with a range of neurological manifestations including Guillain Barre Syndrome, neuralgic amyotrophy and encephalitis (2). Therefore, in-vitro work on this subject is timely and important. This article is protected by copyright. All rights reserved.

PURPOSE OF REVIEW: Hereditary myelopathies are very diverse genetic disorders, and many of them represent a widespread neurodegenerative process rather than isolated spinal cord dysfunction. This article reviews various types of inherited myelopathies, with emphasis on hereditary spastic paraplegias and spastic ataxias. RECENT FINDINGS: The ever-growing number of myelopathy-causing genes and broadening of phenotype-genotype correlations makes the molecular diagnosis of inherited myelopathies a daunting task...

There is growing evidence that hepatitis E virus (HEV) infection can present with extrahepatic manifestations including neurological disorders. Among these, neuralgic amyotrophy (NA) has been reported to occur in some industrialized countries. We investigated 35 patients with NA and a control group for markers of HEV infection. Acute HEV infection was found in NA patients only and was associated with an inflammatory response in the central nervous system. Shedding of HEV RNA into the cerebrospinal fluid and intrathecal production of anti-HEV IgM occurred in one patient suggesting that HEV is neurotropic...

Hepatitis E virus (HEV) is the most common cause of viral hepatitis worldwide. Genotypes 1 and 2 (GT1 and GT2) are mainly present in developing countries, while GT3 and GT4 are prevalent in developed and high-income countries. In the majority of cases, HEV causes a self-limiting hepatitis. GT3 and GT4 can be responsible for a chronic hepatitis that can lead to cirrhosis in immunocompromized patients, i.e. solid-organ- and stem-cell-transplant-patients, human immunodeficiency virus-infected patients, and patients receiving chemotherapy or immunotherapy...

BACKGROUND: Spinocerebellar ataxia type 2 (SCA2) affects several neurological structures, giving rise to multiple symptoms. However, only the natural history of ataxia is well known, as measured during the study duration. We aimed to describe the progression rate of ataxia, by the Scale for the Assessment and Rating of Ataxia (SARA), as well as the progression rate of the overall neurological picture, by the Neurological Examination Score for Spinocerebellar Ataxias (NESSCA), and not only during the study duration but also in a disease duration model...

Neuralgic amyotrophy (NA) is a neurologic syndrome of unknown etiology primarily affecting the brachial plexus. We are reporting an unusual case of acute bilateral NA that was possibly secondary to Lyme disease. The patient demonstrated significant functional gains and was discharged home after 2 weeks of inpatient rehabilitation, supporting the role of inpatient rehabilitation in acute NA. In this report, we discuss the diagnosis, electrodiagnostic progression, pain management, goals for inpatient rehabilitation, and overall prognosis of NA...

Neuralgic amyotrophy of the shoulder (Parsonage-Turner syndrome) is a rare condition of unknown aetiology which manifests as acute neuropathy of the brachial plexus. Diagnosis is based on typical symptoms and physical examination. In addition, magnetic resonance imaging of the affected shoulder and the cervical spine is advisable, in order to distinguish this syndrome from other conditions with similar symptoms. There is no specific treatment for neuralgic amyotrophy, but in about 50 - 67% of cases complete recovery occurs within two to three years, depending on the severity of the symptoms when they first appear...

BACKGROUND: Spinocerebellar ataxia type 2 (SCA2) is due to a CAG expansion (CAGexp) at ATXN2. SCA2 presents great clinical variability, alongside characteristic ataxia with saccadic slowness. AIMS: To study parkinsonism, dementia, dystonia, and amyotrophy as subphenotypes of SCA2, and to explore the effect of CAG repeats at different loci and of mitochondrial polymorphism A10398G as modifiers of phenotype. METHODS: Symptomatic subjects were classified by presence/absence of neurological signs mentioned above; SARA and NESSCA scores were obtained...

Hepatitis E is the most common cause of hepatitis worldwide. While originally considered a disease of developing countries, it is increasingly recognised in developed countries, probably related to contaminated pork meat, and where infection is often asymptomatic. However, several non-liver manifestations have become apparent, the most important of which are neurological, including Guillain-Barré syndrome (acute inflammatory demyelinating polyradiculoneuropathy (AIDP)), neuralgic amyotrophy and meningoencephalitis...

Hirayama disease (HD) is a rare motor neuron disorder that involves a single upper extremity. It is clinically characterized by weakness and atrophy of the muscles of the hand and forearm. This article presents a 19-year-old woman who visited the orthopedics outpatient clinic with weakness and atrophy in her right hand and was clinically diagnosed with advanced stage carpal tunnel syndrome and scheduled for surgical intervention; she was later diagnosed with HD by an electrophysiological study. As a result, it has been found that a careful electrophysiological study and neurological examination can be used to diagnose HD...

Nonsystemic vasculitic neuropathy (NSVN) is an under-recognized single-organ vasculitis of peripheral nerves that can only be diagnosed with a nerve biopsy. A Peripheral Nerve Society guideline group published consensus recommendations on the classification, diagnosis and treatment of NSVN in 2010, and new diagnostic criteria for vasculitic neuropathy were developed by the Brighton Collaboration in 2015. In this Review, we provide an update on the classification, diagnosis and treatment of NSVN. NSVN subtypes include Wartenberg migratory sensory neuropathy and postsurgical inflammatory neuropathy...

Neuralgic Amyotrophy (NA) or Parsonage-Turner syndrome is an idiopathic neuropathy commonly affecting the brachial plexus. Associated phrenic nerve involvement, though recognised, is thought to be very rare. We present a case series of four patients (all male, mean age 53) presenting with dyspnoea preceded by severe self-limiting upper limb and shoulder pain, with an elevated hemi-diaphragm on clinical examination and chest X-ray. Neurological examination of the upper limb at the time of presentation was normal...

Metastasis of breast cancer is often detected through a long-term course and difficult to diagnose. We report a case of brachial plexopathy suspected to be the initial lesion of breast cancer metastasis, which was only detected by magnetic resonance (MR) neurography. A 61-year-old woman was admitted to our hospital within 2 years after operation for breast cancer because of progressive dysesthesia and motor weakness initially in the upper limb on the affected side and subsequently on the contralateral side...

BACKGROUND: Hirayama's disease (HD), is a benign, self-limited, motor neuron disease, characterized by asymmetric weakness and atrophy of one or both distal upper extremities. In the present study we report the clinical, electrophysiological and MRI features of a group of Italian patients, with review of the literature. Moreover we propose an optimized MRI protocol for patients with suspected or diagnosed HD in order to make an early diagnosis and a standardized follow up. METHODS: Eight patients with clinical suspicion of Hirayama disease underwent evaluation between January 2007 and November 2013...
