12、 but has limited diagnostic evaluation.However, rare localizations of peripheral neuropathy often require more extensivediagnostic testing and different treatments.OBJECTIVE: To describe rare localizations of peripheral neuropathy, including theappropriate diagnostic evaluation and available treatme
13、nts.EVIDENCE REVIEW: References were identified from PubMed searches conducted on May29, 2015, with an emphasis on systematic reviews and randomized clinical trials. Articles were also identified through the use of the authors own files. Searchterms included common rare neuropathy localizations and
14、their causes, as well as epidemiology, pathophysiology, diagnosis, and treatment.FINDINGS: Diffuse, nonlength-dependent neuropathies, multiple mononeuropathies,polyradiculopathies, plexopathies, and radiculoplexus neuropathies are rareperipheral neuropathy localizations that often require extensive
15、diagnostictesting. Atypical neuropathy features, such as acute/subacute onset, asymmetry,and/or motor predominant signs, are frequently present. The most common diffuse, nonlength-dependent neuropathies are Guillain-Barr syndrome, chronicinflammatory demyelinating polyneuropathy, multifocal motor ne
16、uropathy, andamyotrophic lateral sclerosis. Effective disease-modifying therapies exist formany diffuse, nonlength-dependent neuropathies including Guillain-Barr syndrome,chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy,and some paraprotein-associated demyelinating neur
17、opathies. Vasculitic neuropathy(multiple mononeuropathy) also has efficacious treatment options, but definitive evidence of a treatment effect for IgM anti-MAG neuropathy and diabeticamyotrophy (radiculoplexus neuropathy) is lacking.CONCLUSIONS AND RELEVANCE: Recognition of rare localizations of per
18、ipheralneuropathy is essential given the implications for diagnostic testing andtreatment. Electrodiagnostic studies are an important early step in thediagnostic evaluation and provide information on the localization andpathophysiology of nerve injury.PMID: 26437251 PubMed - in process4.

29、(MDs) and fasciculation potentials (FPs) in motorneuron disease (MND).METHODS: Patients were eligible when they had MND in their differential diagnosisand were referred for electromyogram (EMG). Stimulated high-density surface EMGof the thenar muscles was performed on the same day as standard EMG ex
30、amination. High-density recordings were analysed for presence of MDs and needle EMG of anymuscle investigated in the cervical region for presence of FPs.RESULTS: Of the 61 patients enrolled in this diagnostic study, 24 patients wereclinically diagnosed with amyotrophic lateral sclerosis (ALS) and 11
31、 patientswith progressive muscular atrophy (PMA). Another diagnosis was made in 26patients. Sixteen patients in whom MDs were detected were diagnosed with eitherALS (n=11) or PMA (n=5; sensitivity=47.1%, PPV=94.1%). MDs were detected in only one patient initially diagnosed with PMA, but in whom late
32、r on, multifocal motor neuropathy could not be excluded (specificity=96.2%). Electrically elicited MDshad a higher specificity than FPs (96.2% vs 53.9%, p0.001, n=26) and lowersensitivity (47.1% vs 85.3%, p=0.002, n=34). When considering presence of MDs in MND as neurogenic EMG abnormality, lower mo
33、tor neuron involvement of 1 EMGregion increased from 50% to 73.5% (p=0.008, n=34).CONCLUSIONS: Electrically evoked MDs are highly specific for ALS and PMA and are an early sign of lower motor neuron dysfunction.Published by the BMJ Publishing Group Limited.

37、ological dysfunction has not been elucidated. Twopatients diagnosed with multifocal acquired demyelinating sensory and motorneuropathy were evaluated with nerve conduction studies, including short segment nerve conduction studies to precisely localise motor conduction block, andultrasound studies of
38、 corresponding nerve trunks. Motor conduction block wasidentified in each patient (upper limb nerves in two patients), superimposed onadditional demyelinating neurophysiological features. Upper limb ultrasoundstudies demonstrated focal nerve enlargement that precisely correlated withneurophysiologic
39、al conduction block. The results of this study suggest thatfactors contributing to focal structural abnormalities in multifocal acquireddemyelinating sensory and motor neuropathy are also those that produce conductionblock.Copyright 2015 Elsevier B.V.

49、cInstitute for Rare Diseases (IPER), Hospital Sant Joan de Du, P Sant Joan deDu no. 2, 08950 Barcelona, Spain.Charcot-Marie-Tooth disease (CMT) is a complex disorder with wide geneticheterogeneity. Here we present a new axonal Charcot-Marie-Tooth disease form,associated with the gene microrchidia fa
50、mily CW-type zinc finger 2 (MORC2).Whole-exome sequencing in a family with autosomal dominant segregation identifiedthe novel MORC2 p.R190W change in four patients. Further mutational screening in our axonal Charcot-Marie-Tooth disease clinical series detected two additionalsporadic cases, one patie
51、nt who also carried the same MORC2 p.R190W mutation and another patient that harboured a MORC2 p.S25L mutation. Genetic and in silicostudies strongly supported the pathogenicity of these sequence variants. Thephenotype was variable and included patients with congenital or infantile onset, as well as
52、 others whose symptoms started in the second decade. The patients with early onset developed a spinal muscular atrophy-like picture, whereas in thelater onset cases, the initial symptoms were cramps, distal weakness and sensory impairment. Weakness and atrophy progressed in a random and asymmetric f
53、ashionand involved limb girdle muscles, leading to a severe incapacity in adulthood.Sensory loss was always prominent and proportional to disease severity.Electrophysiological studies were consistent with an asymmetric axonal motor and sensory neuropathy, while fasciculations and myokymia were recor
54、ded ratherfrequently by needle electromyography. Sural nerve biopsy revealed pronouncedmultifocal depletion of myelinated fibres with some regenerative clusters andoccasional small onion bulbs. Morc2 is expressed in both axons and Schwann cells of mouse peripheral nerve. Different roles in biologica
55、l processes have beendescribed for MORC2. As the silencing of Charcot-Marie-Tooth disease genes havebeen associated with DNA damage response, it is tempting to speculate that aderegulation of this pathway may be linked to the axonal degeneration observed inMORC2 neuropathy, thus adding a new pathoge
