BACKGROUND Idiopathic inflammatory myopathies are autoimmune disorders that can involve the skin, joints, muscles, and lungs. The most common of these disorders are dermatomyositis, polymyositis, overlap syndrome, and inclusion body myositis. Necrotizing autoimmune myopathy is an idiopathic inflammatory myopathy that is rarely associated with Sjögren's syndrome. The most common lung findings associated with anti-EJ antisynthetase syndrome are nonspecific interstitial pneumonia and usual interstitial pneumonia; this condition is rarely associated with fibrinous and organizing pneumonia...

Breast cancers are the most common cancers in women. However, breast cancer occurring in a pectoralis major myocutaneous flap is extremely rare. This article describes a case of breast cancer occurring in such a flap used for reconstruction of the tongue in a 72-year-old woman. Follow-up computed tomogram depicted a slowly growing mass in the flap. Thirty-nine months postoperatively, a fine-needle aspiration biopsy specimen taken from the lesion suggested glandular carcinoma. The patient was diagnosed with breast cancer in the neck area of the flap and tumor excision was performed...

Multiple acyl-CoA dehydrogenation deficiency is genetically heterogenous metabolic disease with mutations in genes involved in electron transfer to the mitochondrial respiratory chain. Disease symptoms vary from severe neonatal form to late-onset presentation with metabolic acidosis, lethargy, vomiting, muscle pain and weakness. Riboflavin therapy has been shown to ameliorate diseases symptoms in some of these patients. Recently, mutations in FAD synthase have been described to cause multiple acyl-CoA dehydrogenation deficiency...

BACKGROUND: Alpha tocopherol (α-TP) supplementation is recommended for the prevention of various equine neuromuscular disorders. Formulations available include RRR-α-TP acetate powder and a more expensive but rapidly water-dispersible liquid RRR-α-TP (WD α-TP). A cost-effective means to rapidly increase serum and CSF α-TP with WD-α-TP and then sustain concentrations with RRR-α-TP acetate has not been reported. OBJECTIVES: To evaluate serum, CSF and muscle α-TP concentrations in an 8-week dosing regimen where horses were transitioned from WD RRR-α-TP to RRR-α-TP acetate...

Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy...

Leigh syndrome (LS) is a progressive neurodegenerative disorder of infancy and early childhood. It is clinically diagnosed by typical manifestations and characteristic computed tomography (CT) or magnetic resonance imaging (MRI) studies. Unravelling mitochondrial respiratory chain (MRC) dysfunction behind LS is essential for deeper understanding of the disease, which may lead to the development of new therapies and cure. The aim of this study was to evaluate the clinical validity of various diagnostic tools in confirming MRC disorder in LS and Leigh-like syndrome (LL)...

BACKGROUND: It is known from clinical practice and observational studies that elderly patients with a diagnosis of inflammatory rheumatic diseases (IRD) bear a significantly increased risk for cardiovascular diseases such as coronary artery disease (CAD) and heart failure. The molecular mechanism, however, is still not known. Recently, high mobility group protein B1 (HMGB1), a ubiquitous, highly conserved single polypeptide expressed in all mammal eukaryotic cells, has been identified to mediate myocardial dysfunction in vitro once released from the nuclei of cardiomyocytes...

Statins are efficient cholesterol-lowering medicines utilized worldwide. However, 10% of patients suffer from adverse effects specially related to skeletal muscle function. Pro- or anti-oxidant effects of statins have been reported. Here we hypothesized that statins induce muscle mitochondrial oxidative stress leading to mitochondrial permeability transition (MPT) which may explain statin muscle toxicity. Thus, our aims were to investigate the effects of statin chronic treatment on muscle mitochondrial respiration rates, MPT and redox state indicators in the context of hypercholesterolemia...

Objective: Few methods enable molecular and cellular studies of vascular aging or type-2 diabetes (T2D). Here we report a new approach to studying human vascular smooth muscle cell (VSMC) pathophysiology by examining VSMCs differentiated from progenitors found in skin. Approach and Results: Skin-derived precursors (SKPs) were cultured from biopsies (N=164, ~1 cm(2)) taken from the edges of surgical incisions of older adults (N=158; males 72%; mean age 62.7±13 years) undergoing cardiothoracic surgery, and differentiated into VSMCs at high efficiency (>80% yield)...

Idiopathic Inflammatory Myopathy (IIM) is a common skeletal muscle disease that relates to weakness and inflammation of muscle. Early diagnosis and prognosis of different types of IIMs will guide the effective treatment. Interpretation of digitized images of the cross section muscle biopsy, which is currently done manually, provides the most reliable diagnostic information. With the increasing volume of images, the management and manual interpretation of the digitized muscle images suffer from low efficiency and high interobserver variabilities...

The present study aimed to analyze the association of transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF) expression levels in skeletal muscle with the clinical manifestation of Duchenne muscular dystrophy (DMD). A total of 18 cases of DMD, which were confirmed by routine pathological diagnosis were recruited into the present study, along with 8 subjects who suffered from acute trauma but did not present any neuromuscular diseases and were enrolled as the healthy controls. Immunohistochemical staining was used to detect the expression levels of CTGF and TGF-β1 in muscle biopsy specimens...

Inherited and acquired muscular weakness is caused by multiple conditions. While the inherited ones are mostly caused by mutations in genes coding for myopathic or neurogenic diseases, the acquired ones occur due to inflammatory, endocrine, or toxic etiologies. Precise diagnosis of a specific disease may be challenging and may require a multidisciplinary approach. What is the current place for a diagnostic biopsy of skeletal muscle? Diagnostic muscle biopsy lost in this context its first-tier place in the primary diagnostic workup for some diseases, but it is still mandatory for others...

Muscle mass in humans is inversely associated with circulating levels of inflammatory cytokines, but the interaction between ageing and training on muscle composition and the intra-muscular signalling behind inflammation and contractile protein synthesis and degradation is unknown. We studied 15 healthy life-long endurance runners, 12 age-matched untrained controls, 10 young trained and 12 young untrained individuals. Thigh muscle composition was investigated by magnetic resonance imaging (MRI), where non-contractile intramuscular tissue (NCIT) area (fat and connective tissue) was found to be greater in older but lower in trained individuals...

Alterations in mitochondrial respiration are an important hallmark of Huntington's disease (HD), one of the most common monogenetic causes of neurodegeneration. The ubiquitous expression of the disease causing mutant huntingtin gene raises the prospect that mitochondrial respiratory deficits can be detected in skeletal muscle. While this tissue is readily accessible in humans, transgenic animal models offer the opportunity to cross-validate findings and allow for comparisons across organs, including the brain...
