The objective of this study is to report a Brazilian patient and his family with inclusion body myopathy associated with Paget's disease of bone and frontotemporal dementia (IBMPFD). A systematic review of the literature on the valosin-containing protein (VCP) mutation was also performed. The proband (patient) was initially treated as a case of possible refractory polymyositis with Paget's disease and later as an inclusion body myopathy. However, after admission to our service, and considering his personal and familial antecedents, whole exome sequencing was performed revealing valosin-containing protein (VCP) c...

Dermatomyositis (DM) is an idiopathic inflammatory myopathy characterized by the presence of skin lesions and inflammation of skeletal muscles; however, this feature may be absent in amyopathic DM. DM is a rare disease, occurring at any age, and has two peaks of incidence: one in childhood between 5 and 15 years of age and one in adulthood between 40 and 60 years, with a female preponderance. DM has been associated with malignancy; therefore, every newly diagnosed patient should undergo screening investigations, but evidence-based guidelines on their extension are lacking...

The goal of this paper was to evaluate the possibility of bi-component T1ρ and T2 relaxation mapping of human skeletal muscle at 3 T in clinically feasible scan times. T1ρ- and T2-weighted images of calf muscle were acquired using a modified 3D-SPGR sequence on a standard 3 T clinical MRI scanner. The mono- and biexponential models were fitted pixel-wise to the series of T1ρ and T2 weighted images. The biexponential decay of T1ρ and T2 relaxations was detected in ~30% and ~40% of the pixels across all volunteers, respectively...

Dermatomyositis is a rare connective tissue disease of unknown origin, including inflammatory myopathy and cutaneous manifestations. Several pulmonary complications associated to dermatomyositis were described; especially interstitial lung disease. Some rare and particular pulmonary complications were reported in the literature such as pneumodiastinum and pneumothorax. We are describing here, a case report about a female patient, who presented with dermatomyositis associated to pneumomediastinum as a severe and lethal complication without pneumothorax...

Recent studies have revealed the clinical, histological, and pathophysiological characteristics in a group of inflammatory myopathies with selected autoantibodies. We retrospectively compared the clinical manifestations and histological features between 8 anti-mitochondrial (anti-M2) antibody-positive and 33 antibody-negative patients. Patients with anti-M2 antibodies have been previously reported to have delayed diagnostic confirmation and frequent cardiopulmonary complications in comparison to those without the antibodies...

CLINICAL ISSUE: Neurogenic myopathies are primary diseases of the nervous system, which secondarily result in denervation of the target musculature. The spectrum of potential causes is manifold ranging from acute traumatic injuries and chronic compression to neurodegenerative, inflammatory, metabolic and neoplastic processes. STANDARD DIAGNOSTIC METHODS: The medical history, clinical neurological examination, and electrophysiological tests including electromyography and nerve conduction studies are crucial in diagnosing neuropathic myopathies...

Single-nucleotide polymorphisms (SNPs) in the ETS1 gene are associated with several auto-inflammatory diseases. In this study, we determined whether ETS1 gene polymorphisms confer susceptibility to idiopathic inflammatory myopathies (IIMs) in a northern Chinese Han population. DNA samples were collected from 1017 IIM patients: 363 PM cases and 654 DM cases. The results were compared with those of 1280 healthy controls. Five SNPs in the ETS1 region (rs7117932, rs6590330, rs4937362, rs10893845 and rs1128334) were assessed and genotyped using the Sequenom platform...

Lipid-lowering agent-triggered dermatomyositis (DM) or polymyositis (PM) is a rare event. Therefore, the aim of the present study was to describe a series of such cases. A retrospective cohort study of 5 DM and 4 PM cases triggered by prior exposure to lipid-lowering agents between 2001 and 2017 was carried out. All patients, except for two cases, had muscle biopsy compatible with inflammatory myopathy and no serum autoantibodies positive for anti-SRP or anti-HMGCoAR. Median age of the patients at time of diagnosis was 68 years...

Patients presenting with a chin-on-chest deformity, or dropped head syndrome, may have a diagnosis of isolated neck extensor myopathy (INEM). INEM is a diagnosis of exclusion occurring primarily in elderly patients. INEM usually has a benign progression, which may involve the shoulder girdle but does not advance to other muscle groups. Patients without an inflammatory etiology typically experience minimal or no recovery of their symptoms. Dropped head syndrome has various implications on a patient's quality of life and activities of daily living...

After the advances created by the use of cryostat sections and histochemistry 60 years ago, muscle histopathology is now living a real renaissance. In the field of genetic neuromuscular disorders, muscle biopsy analysis is fundamental to address questions about pathogenicity and protein expression when new genes are discovered through next-generation sequencing approaches. Moreover, the identification of the same gene mutated in previously considered distinct histopathologic entities imposes a constant reassessment of morphologic boundaries in several groups of disorders...

BACKGROUND: Patients with suspected idiopathic inflammatory myopathies (IIM) are commonly tested for the presence of anti-nuclear antibodies (ANA) by indirect immunofluorescence (IIF) on HEp-2 cell substrates. However, ANA-IIF false negative tests may occur in IIM because some antigens, such as Jo1 and Ro52, may be scarcely expressed on HEp-2 cells. In addition, cytoplasmic staining is often not appropriately investigated by a specific antibody assay, leading to decreased clinical sensitivity of the ANA test...
