Idiopathic inflammatory myopathies (IIMs) are heterogeneous disorders that affect the skeletal muscles. Polymyositis, dermatomyositis, and inclusion body myositis are major IIM subsets. Immune-mediated necrotizing myopathy became recognized as a potentially new IIM subset. Since the new classification criteria published by the International Myositis Classification Criteria Project have higher sensitivity and specificity for IIM classification and subclassification than the previous criteria, they should help precise diagnosis...

Focal myositis is a very rare form of inflammatory myopathy, with unknown etiology. We describe a 44-year-old previously healthy man who noticed a painless swelling on his left forearm, following trauma over the left cubital fossa. The swelling grew progressively over 2 years. He had otherwise no weakness complaints. Physical and neurological examinations were otherwise normal. Creatine kinase and aldolase levels were increased (1,009 U/L and 11.9 U/L, respectively); autoimmunity panel was negative. MRI showed diffuse edema and gadolinium enhancement of muscles innervated by the median nerve...

Immune-mediated necrotizing myopathies (IMNMs) are a group of acquired autoimmune muscle disorders that have been recently defined. They are characterized by proximal muscle weakness, high levels of creatinine kinase, and myopathic findings on electromyogram (EMG). Muscle biopsy in IMNM differentiates it from the other subgroups of idiopathic inflammatory myositis (IIM) by the presence of myofibre necrosis and prominent regeneration without substantial lymphocytic inflammatory infiltrates. Anti-signal recognition particle (SRP) and anti-3hydroxy-3 methylglutaryl-coenzyme A reductase (HMGCR) autoantibodies were found in two thirds of IMNM patients...

Idiopathic inflammatory myopathies form a heterogeneous group of acquired inflammatory diseases afflicting striated muscles. The disease is frequently accompanied by systemic and organ involvement. Dermatomyositis, polymyositis, cancer associated myositis, immune mediated necrotizing myopathy, myositis in overlap syndromes, juvenile myositis and inclusion body myositis are the most frequently encountered subtypes. The basic manifestation is usually painless muscle weakness brought about by inflammation and by other immune changes at the impacted muscles...

BACKGROUND: Dermatomyositis is a humoral-mediated inflammatory myopathy with symmetrical proximal muscle weakness and dermatological manifestations such as Gottron's papules, heliotrope rash, periungual abnormalities, and flagellate erythema. Erythroderma is a severe and potentially life-threatening dermatological condition with diffuse erythema and scaling involving more than 90% of the skin surface area. Poikiloderma vasculare atrophicans refers to mottled hyperpigmentation and hypopigmentation of the skin with in-between telangiectases and areas of atrophy and is considered a variant of mycosis fungoides...

The thalassemias are the most common single gene disorder in the world. Nowadays, the average life expectancy of patients in developed countries has increased significantly, while, there was an increase of complications. We aimed to investigate peripheral neuropathy and myopathy in this patient group using a neurophysiological study. We performed nerve conduction studies and electromyography of upper and lower extremities on 36 beta-thalassemia major (β-thal) patients. The electrophysiological findings were correlated with demographic data and laboratory parameters of the disease...

A 14-month-old female pitbull terrier mix was presented for evaluation of dysphagia of 8 months' duration secondary to intermittent dorsiflexion of the tongue apex. Physical and neurological examinations were unremarkable with the exception of the dorsiflexed tongue. Serum creatine kinase activity was increased (703 IU/L, reference interval: 55 to 257 IU/L), and electromyography of the tongue demonstrated areas of fibrillation potentials. Histopathology of the tongue showed myopathic changes with excessive variability in myofibre size and endomysial fibrosis...

INTRODUCTION: Polymyositis (PM) is a type of autoimmune, inflammatory myopathy. IgG4-related disease (IgG4-RD) is a recently recognized disease entity characterized by elevated serum IgG4 levels and IgG4 plasma-cell infiltration of various organs. However, several reports have described cases of other diseases that present with those features, suggesting the importance of careful differential diagnosis. Herein, we report the first case of PM with elevated serum IgG4 levels and IgG4 plasma cells in the muscles, mimicking IgG4-RD...

Multimodal intraoperative neurophysiologic monitoring is a reliable tool for detecting intraoperative spine injury and is recommended during surgery for degenerative cervical myopathy (DCM). Somatosensory evoked potential (SEP) can be used to monitor spine and peripheral nerve injury during positioning in surgery for DCM. Compensation technique for transcranial evoked muscle action potentials (tcMEPs) should be adopted in intraoperative monitoring during surgery for DCM. Free-running electromyography is a useful real-time monitoring add-on modality in addition to SEP and tcMEP...

INTRODUCTION: Steroid myopathy is a well-known sign of endogenous Cushing's syndrome as well as a side effect of glucocorticoid administration. The clinical finding of muscle weakness and the clinical inspection of the muscle size are the most commonly used diagnostic tools, sometimes in combination with needle electromyography, but there are no means to detect the myopathy before the appearance of clinical or electrodiagnostic signs. Until now, no guidelines have been produced for a disease-specific evaluation of muscle impairment in patients with Cushing's syndrome...

A 24-year-old woman visited our hospital with a complaint of walking disability. She had no family history of consanguineous marriage, and her developmental history was unremarkable, with good physical performance just before the onset. At the age of 13, she developed difficulty in walking and visited a pediatrician. Her serum CK level was 10,000 IU/l and she was diagnosed with muscular dystrophy by muscle biopsy. At the age of 16, she became wheelchair dependent and was admitted to our hospital. Physical examination revealed diffuse muscle atrophy and proximal weakness, with no calf hypertrophy or selectivity of muscle involvement...

Clevudine was approved as an antiviral agent for hepatitis B virus, which showed marked, rapid inhibition of virus replication without significant toxicity. However, several studies have reported myopathy associated with clevudine therapy. Also, we experienced seven patients who suffered from myopathy during clevudine therapy. To characterize clevudine-induced myopathy, we collected previously reported cases of clevudine myopathy and analyzed all the cases including our cases. We searched electronic databases that were published in English or Korean using PubMed and KoreaMed...

Congenital cataract (CC) is clinically and genetically highly heterogeneous. Here, we enrolled a consanguineous kindred (LUCC15) from Pakistan, with three affected individuals suffering with CC. Exome sequencing revealed a transition mutation [c.149T>C; p.(Ile50Thr)] in INPP5K. Inositol polyphosphate-5-phosphatase K, encoded by INPP5K, is involved in dephosphorylation of phosphatidylinositol (PtdIns) 4,5-bisphosphate, and PtdIns 3,4,5-trisphosphate. Recently, pathogenic variants in INPP5K have been reported in families with congenital muscular dystrophies, intellectual disability, and cataract...
