Abstract
AChR and MuSK double positive myasthenia gravis has been rarely reported. Generally, it occurs in children and adults after thymectomy or immunotherapy. Furthermore, in a few patients with bulbar or respiratory involvement, MuSK antibodies might be detected after clinical deterioration. We report a man with a very late onset myasthenia gravis (86-year-old) and the coexistence of both antibodies at the time of the diagnosis. Despite the presence of MuSK antibodies, he manifested no bulbar symptoms and had a favorable clinical outcome. However, side effects related to low dose pyridostigmine were evident. Hence, double positivity can also occur in elderly and in more benign forms of myasthenia gravis. Other cases of AChR and MuSK double positive myasthenia gravis could allow a better definition of this condition.

Abstract
miRNA expression profile and predicted pathways involved in selected limb-girdle muscular dystrophy (LGMD)2A/2B patients were investigated. A total of 187 miRNAs were dysregulated in all patients, with six miRNAs showing opposite regulation in LGMD2A versus LGMD2B patients. Silico analysis evidence: (1) a cluster of the dysregulated miRNAs resulted primarily involved in inflammation and calcium metabolism, and (2) two genes predicted as controlled by calcium-assigned miRNAs (Vitamin D Receptor gene and Guanine Nucleotide Binding protein beta polypeptide 1gene) showed an evident upregulation in LGMD2B patients, in accordance with miRNA levels. Our data support alterations in calcium pathway status in LGMD 2A/B, suggesting myofibre calcium imbalance as a potential therapeutic target. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
BACKGROUND Myosin heavy chain 7 (MYH7)-related myopathies are emerging as an important group of muscle diseases of childhood and adulthood, with variable clinical and histopathological expression depending on the type and location of the mutation. Mutations in the head and neck domains are a well-established cause of hypertrophic cardiomyopathy whereas mutation in the distal regions have been associated with a range of skeletal myopathies with or without cardiac involvement, including Laing distal myopathy and Myosin storage myopathy. Recently the spectrum of clinical phenotypes associated with mutations in MYH7 has increased, blurring this scheme and adding further phenotypes to the list. A broader disease spectrum could lead to misdiagnosis of different congenital myopathies, neurogenic atrophy and other neuromuscular conditions. RESULTS As a result of a multicenter Italian study we collected clinical, histopathological and imaging data from a population of 21 cases from 15 families, carrying reported or novel mutations in MYH7. Patients displayed a variable phenotype including atypical pictures, as dropped head and bent spine, which cannot be classified in previously described groups. Half of the patients showed congenital or early infantile weakness with predominant distal weakness. Conversely, patients with later onset present prevalent proximal weakness. Seven patients were also affected by cardiomyopathy mostly in the form of non-compacted left ventricle. Muscle biopsy was consistent with minicores myopathy in numerous cases. Muscle MRI was meaningful in delineating a shared pattern of selective involvement of tibialis anterior muscles, with relative sparing of quadriceps. CONCLUSION This work adds to the genotype-phenotype correlation of MYH7-relatedmyopathies confirming the complexity of the disorder.

Abstract
Scapuloperoneal spinal muscular atrophy (SPSMA) is a rare autosomal dominant disorder caused by heterozygous mutations in the transient receptor potential cation channel (TRPV4) gene, characterized by progressive scapuloperoneal atrophy and weakness. Additional features, such as vocal cord paralysis, scoliosis and/or arthrogryposis, are likely to occur. We report the first Italian family with SPSMA, harboring the c.806G>A mutation in TRPV4 gene (p. R269H). The pattern of expression was variable: the father showed a mild muscular involvement, while the son presented at birth skeletal dysplasia and a progressive course. We reinforce the concept that the disease can be more severe in the following generations. The disorder should be considered in scapuloperoneal syndromes with autosomal dominant inheritance and a neurogenic pattern. The presence of skeletal deformities strongly supports this suspicion. An early diagnosis of SPSMA may be crucial in order to prevent the more severe congenital form.

Abstract
Lambert-Eaton myasthenic syndrome is a neuromuscular junction disorder characterized by proximal limb muscle weakness, fatigability, decreased deep-tendon reflexes, and autonomic symptoms. There are 2 forms of Lambert-Eaton myasthenic syndrome: one most frequently associated with small-cell lung cancer (P-Lambert-Eaton myasthenic syndrome) and the other that is a pure autoimmune form (NP-Lambert-Eaton myasthenic syndrome). Lambert-Eaton myasthenic syndrome is a very rare disorder in children younger than age 12 years. Herein, we report a 25-year-old man with NP-Lambert-Eaton myasthenic syndrome, which onset was at the age of 10 years. To date, this is the most long-term follow-up of NP-Lambert-Eaton myasthenic syndrome in childhood. In our patient, the only symptomatic treatment with 3,4-diaminopyridine phosphate has been sufficient to guarantee him a good quality of life. Our data remind physicians to keep in mind the diagnosis of Lambert-Eaton myasthenic syndrome in children with a proximal myopathic pattern and they confirm the specificity of compound muscle action potential incremental pattern after brief maximal effort in Lambert-Eaton myasthenic syndrome.

Abstract
The clinical approach to patients with amyotrophic lateral sclerosis (ALS) has been largely modified by the identification of novel genes, the detection of gene mutations in apparently sporadic patients, and the discovery of the strict genetic and clinical relation between ALS and frontotemporal dementia (FTD). As a consequence, clinicians are increasingly facing the dilemma on how to handle genetic counselling and testing both for ALS patients and their relatives. On the basis of existing literature on genetics of ALS and of other late-onset life-threatening disorders, we propose clinical suggestions to enable neurologists to provide optimal clinical and genetic counselling to patients and families. Genetic testing should be offered to ALS patients who have a first-degree or second-degree relative with ALS, FTD or both, and should be discussed with, but not offered to, all other ALS patients, with special emphasis on its major uncertainties. Presently, genetic testing should not be proposed to asymptomatic at-risk subjects, unless they request it or are enrolled in research programmes. Genetic counselling in ALS should take into account the uncertainties about the pathogenicity and penetrance of some genetic mutations; the possible presence of mutations of different genes in the same individual; the poor genotypic/phenotypic correlation in most ALS genes; and the phenotypic pleiotropy of some genes. Though psychological, social and ethical implications of genetic testing are still relatively unexplored in ALS, we recommend multidisciplinary counselling that addresses all relevant issues, including disclosure of tests results to family members and the risk for genetic discrimination.

Abstract
BACKGROUND Hereditary inclusion-body myopathy or distal myopathy with rimmed vacuoles (h-IBM/DMRV) is due to mutations of the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene, which codes for an enzyme of the sialic acid biosynthetic pathway. By Western blot (WB) analysis, we have previously shown that in h-IBM/DMRV muscle, the neural cell adhesion molecule (NCAM) has increased electrophoretic mobility that reflects reduced sialylation of the protein. OBJECTIVE To identify patients with h-IBM/DMRV with atypical clinical or pathologic phenotype using NCAM analysis and the possible cellular mechanism associated with the overall abnormal sialylation of NCAM observed in this disorder. METHODS WB analysis of NCAM was performed on muscle biopsies of 84 patients with an uncharacterized muscle disorder who were divided in the following 2 groups: 1) 46 patients with a proximal muscle weakness in whom the main limb-girdle muscular dystrophy syndromes had been ruled out; and 2) 38 patients with a distal distribution of weakness in whom a neurogenic affection had been excluded. Patients in whom a reduced sialylation of NCAM was suspected were studied for the presence of GNE mutations. RESULTS In 3 patients, we found that NCAM had increased electrophoretic mobility, thus suggesting an abnormal sialylation of the protein. The genetic study demonstrated that they all carried pathogenic GNE mutations. Further studies demonstrated that hyposialylated NCAM, showing increased electrophoretic mobility on WB, is expressed by nonregenerating fibers in h-IBM/DMRV muscle. CONCLUSIONS WB analysis of NCAM may be instrumental in the identification of h-IBM/DMRV with atypical clinical or pathologic features.

Abstract
Wound botulism is a rare infectious disease that is becoming a frequent complication of parental drug use. Diagnosis is often difficult and based on clinical suspicion. We report the first Italian case of wound botulism due to intramuscular heroin injection in a 48-year-old man with an acute onset of slurred speech and dysphagia. The most considerable finding of electrophysiological study was the reduction in amplitude of compound muscle action potential which should be considered a useful initial electrodiagnostic sign in the clinical context of botulism. Alerting clinicians to botulism is crucial for a rapid diagnosis and appropriate treatment and thus decreasing mortality and complications.

Abstract
Impaired muscle function may be a predominant aspect of hypothyroidism and is virtually present in all patients with overt thyroid failure. Less common is the onset of hypothyroidism with clinical features mimicking a polymyositis. We have observed 3 patients, whose age ranged 63-68 years, presenting with muscle aches, cramps, proximal weakness and stiffness. Two patients had dysphagia. Serum creatine kinase (CK) and electromyography (EMC) were altered in two patients. Muscle biopsy showed type II atrophy, sporadic type I and type II grouping, "core-like" areas, and some myopathic changes such as central nuclei and muscle necrosis. No inflammatory changes were present. Immunohistochemistry of several muscle cytoskeletal proteins revealed increased desmin in "corelike" areas. Detection of serum thyroid hormone levels revealed very low triiodo-L-thyronine (T3) and thyroxine (T4), whereas thyroid-stimulating hormone (TSH) was greatly increased as well as serum anti-thyroglobulin, anti-peroxidase and anti-microsome antibodies. The patients were diagnosed having a hypothyroid myopathy due to Hashimoto thyroiditis. L-thyroxine treatment normalized clinical and hormone levels, but serum antibodies remained elevated. Muscle biopsy was fundamental to establish the correct diagnosis in our patients. Presence of over-expression of desmin in cores, as described in target lesions in neurogenic diseases, may suggest a nerve-mediated pathogenesis of hypothyroid myopathy.

Abstract
OBJECTIVES To describe clinical, electrophysiological and genetic data of five unrelated Sicilian pedigrees harbouring a heterozygous Ser78Leu mutation in the myelin protein zero (MPZ) extracellular domain. MATERIALS AND METHODS Clinical, electrophysiological and genetic findings of 16 patients were reported. Polymorphic markers flanking the coding sequence of MPZ gene were also analysed. RESULTS A wide range of age at onset was observed in families 1 and 3, with a clinical heterogeneity, in terms of severity of the disease, within the same family (families 1 and 3), and among families. A markedly unsteady gait was a distinctive feature of many members of family 1. All patients in family 2 complained of severe cramps and painful paresthesia. Molecular genetic analysis showed that all affected subjects shared a common haplotype at three microsatellite loci D1S2858, D1S2624 and D1S484. CONCLUSIONS Our study provides further evidence that phenotypic features of MPZ mutations can vary within and among different families. High frequency of Ser78Leu mutation in Sicily as well as the results of haplotype analyses suggest that the mutation may have been inherited from a common ancestor.

Abstract
OBJECTIVES Idiopathic inflammatory myopathies (IIM), including dermatomyositis (DM), polymyositis (PM), sporadic inclusion-body myositis (s-IBM) and focal myositis (FM) are a heterogeneous group of autoimmune disorders of skeletal muscle. An increased transglutaminase 2 (TG2) expression has been found in DM, PM and s-IBM. The aim of our study was to investigate TG2 expression in FM in comparison with other IIM. MATERIALS AND METHODS We re-examined tissue material we have gathered in the course of our previous studies on IIM, investigating muscle expression of TG2 in patients with FM in comparison with DM, PM and s-IBM using immunocytochemistry and real-time RT-PCR. RESULTS Immunocytochemistry revealed an increased TG2 signal in endomysial vessels, in atrophic and degenerating/regenerating muscle fibres in PM, DM, s-IBM and FM; in s-IBM, some vacuoles were immunostained too. Real-time RT-PCR study confirmed a significantly increased expression of TG2 in all IIM muscles examined. CONCLUSIONS Our study demonstrates the presence of TG2 in FM muscles. The study suggests that TG2 expression does not represent a distinctive marker to differentiate FM from generalized IIM. TG2 over-expression in inflamed skeletal muscle does not seem have a pathogenetic role in such a disease, but it could represent a way to contain the inflammatory process.

Abstract
BACKGROUND Mutations in the LMNA gene, encoding human lamin A/C, have been associated with an increasing number of disorders often involving skeletal and cardiac muscle, but no clear genotype/phenotype correlation could be established to date. METHODS We analyzed the LMNA gene in a large cohort of patients mainly affected by neuromuscular or cardiac disease and clustered mutated patients in two groups to unravel possible correlations. RESULTS We identified 28 variants, 9 of which reported for the first time. The two groups of patients were characterized by clinical and genetic differences: 1) patients with childhood onset displayed skeletal muscle involvement with predominant scapuloperoneal and facial weakness associated with missense mutations; 2) patients with adult onset mainly showed cardiac disorders or myopathy with limb girdle distribution, often associated with frameshift mutations presumably leading to a truncated protein. CONCLUSIONS Our findings, supported by meta-analysis of previous literature, suggest the presence of two different pathogenetic mechanisms: late onset phenotypes may arise through loss of function secondary to haploinsufficiency, while dominant negative or toxic gain of function mechanisms may explain the severity of early phenotypes. This model of patient stratification may help patient management and facilitate future studies aimed at deciphering lamin A/C pathogenesis.

Abstract
OBJECTIVES An increased expression of adenine nucleotide translocator (ANT1), found in facioscapulohumeral muscular dystrophy (FSHD), is known to lead to a decrease in nuclear factor-kappaB (NF-kappaB) DNA binding and to sensitize muscle cells to oxidative stress and apoptosis. Receptor for advanced glycation end products (RAGE) mediated by NF-kappaB activation is involved in proinflammatory pathomechanism and in muscle fiber regeneration in inflammatory myopathies and in limb girdle muscular dystrophy. Oxidative stress can stimulate RAGE- NF-kappaB pathway. Our purpose was to verify if oxidative stress may induce RAGE- NF-kappaB pathway activation in FSHD, contributing to the pathogenesis of such a disease. MATERIALS AND METHODS On muscle samples of eight patients with FSHD, eight patients with Duchenne muscular dystrophy and eight normal controls the following studies were carried out: immunocytochemistry for activated NF-kappaB; electrophoretic mobility shift assay of NF-kappaB DNA binding activity; Western blot studies of RAGE and ANT1; hydrogen peroxide (HP), peroxidase and glutathione peroxidase (GPx) assays. RESULTS An increased RAGE and ANT1 expression in FSHD with moderate increase of NF-kappaB DNA binding activity was found together with an increased production of HP and a reduced activity of peroxidase and GPx. CONCLUSIONS Our data confirm that response to oxidative stress and ANT1 increased activity are early events in FSHD muscle. The study also reveals that the RAGE- NF-kappaB pathway, induced by oxidative stress, is activated independently of the presence of a clear histochemical evidence of muscle damage in FSHD.

Abstract
At age of 57 years, a man experienced an episode of rhabdomyolysis. On that occasion muscle biopsy was not performed, however monoclonal gammopathy of undetermined significance (MGUS) was diagnosed. Further he developed a moderate proximal muscle weakness with CK level persistently elevated (1000-1200U/l). When he came to our observation, at age 67, a muscle biopsy revealed an amyloid myopathy and multiple myeloma was at the same time disclosed. Terminal complement complex C5b9 (membrane attack complex) deposits were found in the vessel walls and muscle fibers surface depicted by amyloid. Our case suggests to keep in mind the possibility that amyloid myopathy may begin as an isolate episode of rhabdomyolysis. The detection of complement complex C5b9 suggests that complement cascade is implicated in the muscular damage of amyloid myopathy.

Abstract
Glycogenosis type III (Cori disease) is an autosomal recessive disorder caused by the deficiency of the glycogen debranching enzyme, encoded by the AGL gene, and existing in six isoforms alternately spliced in a tissue-specific way. Generally, disease onset occurs early on starting from the first year of life, with hepatomegaly, hypoglycemia, hyperlipidemia, increased CK levels, and, in some cases, short stature and slight mental retardation. Frequently, hepatomegaly tends to resolve spontaneously and inexplicably during childhood, when myopathy, often associated with cardiomyopathy, arises. This disease is known to lack almost invariably clear links between the genotype and clinical phenotype. We describe nine new mutations in Italian patients: four nonsense (p.Arg285X, p.Lys422X, p.Arg910X, p.Arg977X), three frameshift (c.442delA, c.753_756delGACA, c.3963delG), and two missense (p.Ala1120Pro, p.Arg524His). Particularly, the nonsense p.Arg285X is linked to an exonic splicing enhancer and it was found to produce two species of transcripts at the same time. Moreover, we discuss a subgroup of subjects carrying c.2681+1G>A, which has proven to be the most frequent mutation among our patients. The previously described c.664+3A>G was also detected in two patients, both homozygous. The present work is yet another confirmation that the individual genetic background plays a pivotal role in influencing the phenotypes, as occurs in other metabolic diseases.

Abstract
The objective was to report a clinical, pathological and muscle magnetic resonance (MR) study of an Italian family with an autosomal dominant inclusion body myopathy (AD-IBM). Eight subjects (age range 20-56 years; 5 females and 3 males) belonging to four generations were studied. Onset of disturbances (distal weakness at lower limbs) ranged from 20 to 28 years. CK levels were increased to five times. Only in an early stage oedema of involved muscles has been demonstrated by muscle MR. Quadriceps femoris was characteristically spared; in the last phases a mild involvement of the vasti became evident with persistent sparing of the rectus femori. Rimmed vacuoles and hyperphosphorylated tau filaments were evident at muscle biopsy. Linkage analysis excluded the association of the disease to chromosome loci 14q11, 17p13.1, 2p13, 19p13. The study suggests that quadriceps sparing is a characteristic feature also of AD-IBM. This finding could represent a muscle-image hallmark helpful in diagnosis of autosomal dominant muscular disorders.

Abstract
Limb-girdle myasthenia is a rare disorder which includes familial and autoimmune forms. Myasthenia gravis is an uncommon disease in children and its diagnosis may be difficult. We report here five cases of autoimmune juvenile LGM starting before the age of 16 years with attention to clinical diagnostic difficulties, evolution, laboratory and instrumental data as well as response to treatment. Diagnosis of limb-girdle myasthenia requires a strong index of suspicion also in childhood. We suggest that this form be suspected in children with unclassifiable myopathy, mostly affecting deltoid muscles and lower extremities.

Abstract
OBJECTIVES The aim of our study was to investigate immunoexpression of matrix metalloproteinases MMP2, MMP7 and MMP9 in muscle specimens from patients with focal myositis (FM) vs polymyositis (PM) and dermatomyositis. MATERIALS AND METHODS We studied muscle biopsy samples from seven patients affected by FM; samples from five patients each with PM and dermatomyositis were studied as disease controls. RESULTS MMP2 immunoreactivity was present in PM and dermatomyositis, MMP7 only in PM, and MMP9 in PM, dermatomyositis and FM. CONCLUSIONS Our results confirm that increased MMP9 immunoreactivity in muscle fibres is a common feature of all inflammatory myopathies and suggest that MMP2 and MMP7 cannot be implicated in the inflammatory events of FM.

Abstract
A 40-yr-old male was admitted to the intensive care unit following blunt chest trauma. He had multiple rib fractures, bilateral pneumothoraces, and acute respiratory failure requiring mechanical ventilation. Sedation was achieved with midazolam and morphine, and later with propofol. The patient was paralysed with a continuous infusion of cisatracurium 1.42-5.75 micro g kg(-1) min(-1). Methylprednisolone 125 mg i.v. every 12 h was also started. After discontinuation of the cisatracurium infusion 7 days later, the patient manifested a flaccid quadriplegia with absence of deep-tendon reflexes. No sensory deficits were observed. Electromyography (EMG), repetitive nerve stimulation testing, and single fibre EMG (SFEMG) were performed at regular intervals after stopping cisatracurium. Clinical symptoms and electrophysiological examinations supported the diagnosis of acute motor axonal polyneuropathy related to concomitant administration of cisatracurium and corticosteroid therapy.

Abstract
Dysferlin, the protein product of the dysferlin gene (DYSF), has been shown to have a role in calcium-induced membrane fusion and repair. Dysferlin is absent or drastically reduced in patients with the following autosomal recessive disorders: limb-girdle muscular dystrophy type 2B (LGMD-2B), Miyoshi myopathy (MM) and distal anterior compartment myopathy. To date, less than 45 mutations have been described in DYSF and a wide inter- and intra-familial variation in clinical phenotype has been associated with the same mutation. This observation underlines the relevance of any new report describing genotype/phenotype correlations in dysferlinopathic patient and families. Here we present the results of clinical, biochemical and genetic analysis performed on one MM and three LGMD Italian families. By screening the entire coding region of DYSF, we identified three novel mutations (two missense substitutions and one frame shift microdeletion). The possible existence of a founder effect for the Arg959Trp mutation in the Italian population is discussed.

Abstract
Limb-girdle myasthenia is an uncommon disease and includes familial and autoimmune forms. Patients present proximal muscle weakness and wasting, and sometimes fatigability, without cranial nerve involvement and fluctuations. We observed, during a 15-year period, nine subjects with limb-girdle myasthenia, (24-55 years; 8 males, 1 female) who constituted 3.2% of 281 myasthenic patients attending our department. All had previously received a diagnosis different from myasthenia. Diagnosis of limb-girdle myasthenia was established by clinical, muscle biopsy and electrophysiological assessment including repetitive nerve stimulation and single fiber electromyography. Five patients had the familial form with tubular aggregates in skeletal muscle; four patients had the autoimmune form. Patients with the familial form had a good response to acetylcholinesterase inhibitors, and the patients with the autoimmune form responded to immunotherapy. Our findings reinforce the opportunity to suspect limb-girdle myasthenia in unclassifiable proximal myopathies and to differentiate familial from autoimmune cases, especially for therapeutic implications.

Abstract
Although autonomic symptoms are not prominent in dystrophinopathies, a reduced vagal activity and an enhanced sympathetic tone have been found in Duchenne muscular dystrophy. Twenty patients with Becker muscular dystrophy (BMD) were investigated by a battery of six cardiovascular autonomic tests (beat-to-beat variability during quiet breathing and deep breathing, heart rate responses to Valsalva maneuver and standing, blood pressure responses to standing and sustained handgrip) and power spectral analysis (PSA) of heart rate variability. Although 11 patients revealed abnormal findings at some cardiovascular tests, none of them had a definite autonomic damage, as indicated by two or more abnormal tests. The mean results of the single tests did not differ from normal controls, except for the beat-to-beat variability during quiet breathing, which was significantly higher in BMD (p<0.05). Such finding was confirmed by a significantly higher total variance (p<0.05), indicating an increased parasympathetic activity. Spectral components were not significantly different from normal controls. PSA values were not influenced by age, functional ability score or presence of heart abnormalities. Our data suggest that autonomic involvement does not represent a major finding in BMD.
