INTRODUCTION: Spinal infarction accounts for 1% of all strokes. Cardioembolism is a rare cause. Common areas of ischemic spinal damage are watershed in the dorsal or lumbar regions; however cervical spinal cord infarction has been reported previously. CASE REPORT: We present a new case of a man-in-the-barrel syndrome produced by cardiac embolization associated with atrial fibrillation during an acute myocardial infarction, which caused cervical ischemic neuronopathy (infarction of the anterior horn)...

REVIEW
T Kuntzer
This review discusses and summarizes the concept of nodopathies, the diagnostic features, investigations, pathophysiology, and treatment options of chronic inflammatory demyelinating polyradiculoneuropathy, and gives updates on other inflammatory and dysimmune neuropathies such as Guillain-Barré syndrome, sensory neuronopathies, small-fiber-predominant ganglionitis, POEMS syndrome, neuropathies associated with IgM monoclonal gammopathy and multifocal motor neuropathy. This field of research has contributed to the antigenic characterization of the peripheral motor and sensory functional systems, as well as helping to define immune neuropathic syndromes with widely different clinical presentation, prognosis and response to therapy...

We present a patient with congenital spinal muscular atrophy associated with pain, subjective sensory loss, right talipes equinovarus, delayed walking, and progressive gait impairment. A sister and niece reportedly had Charcot-Marie-Tooth 1A, but the patient's electromyogram showed an axonal motor neuropathy or neuronopathy. We identified a c.806G>A TRPV4 gene mutation causing an Arg269His amino acid substitution. TRPV4 mutations cause variable phenotypes including axonal sensorimotor neuropathy and motor neuropathy or neuronopathy...

INTRODUCTION: We investigated whether MR diffusion tensor imaging (DTI) analysis of the cervical spinal cord could aid the (differential) diagnosis of sensory neuronopathies, an underdiagnosed group of diseases of the peripheral nervous system. METHODS: We obtained spinal cord DTI and T2WI at 3 T from 28 patients, 14 diabetic subjects with sensory-motor distal polyneuropathy, and 20 healthy controls. We quantified DTI-based parameters and looked at the hyperintense T2W signal at the spinal cord posterior columns...

Motor neuron diseases such as amyotrophic lateral sclerosis (ALS) are now recognized as multi-system disorders also involving various non-motor neuronal cell types. The precise extent and mechanistic basis of non-motor neuron damage in human ALS and ALS animal models remain however unclear. To address this, we here studied progressive motor neuronopathy (pmn) mice carrying a missense loss-of-function mutation in tubulin binding cofactor E (TBCE). These mice manifest a particularly aggressive form of motor axon dying back and display a microtubule loss, similar to that induced by human ALS-linked TUBA4A mutations...

The presence of P/Q type voltage gated calcium channel (VGCC) antibodies has been strongly correlated with Lambert Eaton Syndrome (LES), present in 90% of non-immunocompromised patients with LES. However, there have been case reports which have shown its association between paraneoplastic syndrome affecting both central nervous system and the peripheral nervous system causing encephalomyelitis and sensory neuronopathy/neuropathy. We present a case of a young man, who presented with encephalomyelitis, and was further noted to have superimposed cervical polyradiculopathy associated with P/Q type VGCC antibodies...

Facial onset sensory and motor neuronopathy (FOSMN) is a recently defined slowly progressive motor neuron disorder. It is characterized by facial onset sensory abnormalities which may spread to the scalp, neck, upper trunk and extremities, followed by lower motor neuron deficits. Bulbar symptoms, such as dysarthria and dysphagia, muscle weakness, cramps and fasciculations, can present later in the course of the disease. We search the PubMed database for articles published in English from 2006 to 2016 using the term of "Facial onset sensory and motor neuronopathy"...

INTRODUCTION: Chediak-Higashi disease (CHD) is a rare autosomal recessive disorder with hematologic, infectious, pigmentary, and neurologic manifestations. Classic CHD (C-CHD) presents in early childhood with severe infectious or hematologic complications unless treated with bone marrow transplantation (BMT). Atypical CHD (A-CHD) has less severe hematologic and infectious manifestations. Both C-CHD and A-CHD develop neurological problems. METHODS: Eighteen patients with CHD (9 A-CHD and 9 C-CHD) underwent electrodiagnostic studies as part of a natural history study (NCT00005917)...

BACKGROUND: Progressive ataxia and palatal tremor (PAPT) can be observed in both acquired brainstem or cerebellar lesions and genetic disorders. PHENOMENOLOGY SHOWN: PAPT due to mutation in POLG, the gene encoding the mitochondrial DNA polymerase. EDUCATIONAL VALUE: POLG mutation should be considered in patients with PAPT, particularly when additional clues such as a sensory neuronopathy or an ophthalmoplegia are present.

Sensory neuronopathy is a well-established presentation in paraneoplastic neurological syndromes that is mostly associated with small cell lung cancer and anti-Hu antibodies. Motor neuronopathy, on the other hand, is an extremely rare observation in this syndrome. A 56-year-old man presented with asymmetric brachial diparesis and sensory ataxia. Electrophysiological studies revealed sensory ganglionopathy and progressive anterior horn degeneration in cervical segments. Small cell lung carcinoma with associated anti-Hu antibodies was later diagnosed...

Primary Sjögren syndrome (SS) is an autoimmune disease mainly affecting the exocrine glands causing a sicca syndrome. Neurological manifestations are rarely seen in SS although they are debilitating. Peripheral neuropathies namely sensory axonal neuropathy and painful small fiber neuropathy are the most frequent neurological manifestations. Sensory neuronopathy (SN) is less frequently seen although leading to more severe handicap.The aim of the study was to analyze the clinical presentation and treatment efficacy in a series of SS-related SN...

Prostate cancer is the most common cancer among American and European men. Nervous system affection caused by local tumor growth or osseous metastases are the main causes of neurological symptoms in prostate cancer patients. Prostate cancer is rarely reported in association with paraneoplastic neurological syndromes (PNS). We have, therefore, studied clinical and paraclinical findings of a series of patients with prostate cancer and PNS, and reviewed cases reported in the literature. Case histories of 14 patients with definite PNS from the PNS Euronetwork database and from the authors' databases were reviewed...

OBJECTIVES: CMT is a group of heterogeneous motor and sensory neuropathies divided into demyelinating (CMT1) and axonal forms (CMT2). Distal Hereditary Motor Neuropathy (dHMN) is a motor neuropathy/neuronopathy which resembles CMT. Final genetic diagnosis is poor in CMT2 and in dHMN when compared with CMT1. Our aim is to report clinical, neurophysiological and genetic findings in a cohort of patients with axonal inherited neuropathies. PATIENTS AND METHODS: We report clinical, neurophysiological and genetic findings from 45 patients with CMT2 or dHMN, coming from 39 unrelated families, observed in our Institute of Neurology over a 20-year period...

BACKGROUND: Patients with inflammatory sensory neuronopathy (SNN) may benefit from immunomodulatory or immunosuppressant treatments if administered timely. Knowing the temporal profile of neuronal loss in dorsal root ganglia will help to ascertain whether a final diagnosis may be reached before the occurrence of irreversible neuronal injuries. Thus, we addressed the evolution of neuronal loss in SNN by using sensory nerve action potentials (SNAPs) as a surrogate marker of neuron degeneration...

BACKGROUND AND PURPOSE: Our aim was to address the correlation between small fiber loss and amyotrophic lateral sclerosis (ALS) for disease onset, phenotype, genotype, duration, severity and sensory findings. METHODS: Consecutive patients referred for suspected ALS were screened. Exclusion criteria were possible ALS and previous diagnosis or known risk factors for small fiber neuropathies. A sural nerve conduction study (NCS) was bilaterally recorded. The ALS functional rating scale revised was administered and loss of functions were calculated using the Milano-Torino staging (MITOS) system...

Peripheral neuropathy is frequent in spinocerebellar ataxia type 2 (SCA2), but the pattern and characteristics of nerve involvement are still an unsettled issue. This study aimed to evaluate the prevalence, extent, and distribution of nerve involvement in SCA2 patients through neurophysiological studies. Thirty-one SCA2 patients and 20 control subjects were enrolled in this study. All subjects were prospectively evaluated through electromyography, including nerve conduction, needle electromyography in proximal and distal muscles of the upper and lower limbs, and sural radial amplitude ratio (SRAR)...
