Semone B Myrie, Mark A Pinder
Skeletal muscle is critical for mobility and many metabolic functions integral to survival and long-term health. Alcohol can affect skeletal muscle physiology and metabolism, which will have immediate and long-term consequences on health. While skeletal muscle abnormalities, including morphological, biochemical and functional impairments are well documented in adults consuming excessive alcohol, there is a scarcity of information about skeletal muscle in the prenatal alcohol exposure (PAE) offspring. This review examines the available studies addressing skeletal muscle abnormalities due to PAE...

BACKGROUND: Systemic corticosteroids are often used to treat atopic dermatitis (AD). However, few studies assessed the safety and efficacy of systemic corticosteroids in AD. OBJECTIVE: To systematically review the literature on efficacy and safety of systemic corticosteroid use (oral, intramuscular, intravenous) in AD. METHODS: PubMed, Embase, Medline, Scopus, Web of Science, and Cochrane Library were searched. We included systematic reviews, guidelines and treatment reviews of systemic corticosteroid use among patients of all ages with a diagnosis of AD (52 reviews and 12 studies)...

REVIEW
M Leya, N J Stone
PURPOSE OF REVIEW: Our aim was to examine the current evidence behind prescribing statins to individuals over 65 years of age with emphasis on those older than 75. Individuals over 75 years of age may often have multiple comorbidities and take many medications. Additionally, they are often underrepresented in randomized controlled trials (RCTs) of statins in older populations. While results of RCTs demonstrate the benefit of statin therapy in both primary and secondary prevention patients, clinicians must more carefully consider adverse effects and drug-drug interactions before prescribing statin therapy as well as determining the intensity in older individuals...

BACKGROUND: Patients with diabetes mellitus (DM) are at risk of experiencing chronic complications such as retinopathy, nephropathy and myopathy. We aimed to evaluate the effects of L-carnitine on type II DM (T2DM)-induced biochemical, contractile and pathological changes in skeletal muscles of rats. METHODS: Thirty-two male Sprague Dawley rats were divided into the control, control+L-carnitine, T2DM and T2DM+L-carnitine groups. Plasma levels of glucose, insulin, malondialdehyde and antioxidants such as reduced glutathione, catalase and superoxide dismutase, haemoglobin A1c (HbA1c), insulin sensitivity index (ISI) as well as the contractile properties of the gastrocnemius muscle were measured...

PURPOSE: Dermatomyositis (DM) represents an auto-immune inflammatory myopathy. In this review, we analyzed the incidence of DM as a clinical manifestation highlighting the peculiar clinical and treatment characteristics of this disease when occurring in the context of different malignancies. METHODS: A systematic literature review was performed based on database search in PubMed/Medline and included English articles until December 2016. RESULTS: In up to 20% of cases DM appears as a paraneoplastic syndrome associated with multiple malignancies such as ovarian, breast, prostate, lung, nasopharyngeal and colorectal cancer, and non-Hodgkin lymphomas...

Wilson's disease is a well-characterized disorder known to cause liver and brain disease due to abnormal copper deposition. Data regarding copper infiltration of the heart is conflicting, and the risk of heart disease has not been well described. We aimed to determine whether Wilson's disease is associated with cardiac myopathy, clinically evident in the atria as atrial fibrillation (AF) and in the ventricles as heart failure (HF). We longitudinally assessed 14.3 million patients in the California Healthcare Cost and Utilization Project database from 2005 through 2009 for diagnoses of Wilson's disease, AF, HF, and covariates using International Classification of Diseases-9th Edition codes...

Pheochromocytomas in pregnancy are rare but potentially lethal. Even rarer is the combination of pheochromocytoma in pregnancy with subsequent development of ectopic Cushing's syndrome. We report a 36-year-old woman, previously diagnosed with essential hypertension, who developed severe hypertension in pregnancy complicated by insulin-dependent gestational diabetes. A cesarean section was performed at 32 weeks following a hypertensive crisis after routine administration of betamethasone. Postnatal persistence of signs and symptoms of catecholamine excess led to the diagnosis of a left adrenal pheochromocytoma...

A common comorbidity of diabetes is skeletal muscle dysfunction, which leads to compromised physical function. Previous studies of diabetes in skeletal muscle have shown alterations in excitation-contraction coupling (ECC)-the sequential link between action potentials (AP), intracellular Ca(2+) release, and the contractile machinery. Yet, little is known about the impact of acute elevated glucose on the temporal properties of AP-induced Ca(2+) transients and ionic underlying mechanisms that lead to muscle dysfunction...

Peripheral neuropathy is one of the most common complications of diabetic hyperglycaemia. Insulin-induced hypoglycaemia (IIH) might potentially exacerbate or contribute to neuropathy as hypoglycaemia also causes peripheral neuropathy. In rats, IIH induces neuropathy associated with skeletal muscle changes. Aims of the present study were to investigate the progression and sequence of histopathologic changes caused by chronic IIH in rat peripheral nerves and skeletal muscle, and whether such changes were reversible...

BACKGROUND: Statins are a class of therapeutics used to regulate serum cholesterol and reduce the risk of heart disease. Although statins are highly effective in removing cholesterol from the blood, their consumption has been linked to potential adverse effects in some individuals. The most common events associated with statin intolerance are myopathy and increased risk of developing type 2 diabetes mellitus. However, the pathological mechanism through which statins cause these adverse effects is not well understood...

Lipodystrophy is a heterogeneous group of disorders characterized by loss of adipose tissue. Here, we report on clinical spectra of neuromuscular manifestations of Turkish patients with lipodystrophy. Seventy-four patients with lipodystrophy and 20 healthy controls were included. Peripheral sensorimotor neuropathy was a common finding (67.4%) in lipodystrophic patients with diabetes. Neuropathic foot ulcers were observed in 4 patients. Drop foot developed in 1 patient with congenital generalized lipodystrophy type 1...

Methylglyoxal (MG) is a reactive dicarbonyl intermediate and a precursor of advanced glycation end products (AGEs). The authors investigated the role played by AGEs in muscle myopathy and the amelioration of its effects by curcumin and gingerol. In addition to producing phenotypical changes, MG increased oxidative stress and reduced myotube formation in C2C12 cells. RAGE (receptor for AGEs) expression was up-regulated and MYOD and myogenin (MYOG) expressions were concomitantly down-regulated in MG-treated cells...

PURPOSE OF REVIEW: Here we summarize the evidence from human studies of the impairments to the structural, functional, and metabolic capacities in skeletal muscle in those with type 1 diabetes (T1D) - a condition known as diabetic myopathy. Given the importance of skeletal muscle for blood lipid and glucose management, the development and progression of diabetic myopathy would not only lead to increased insulin resistance, but also impact the ability to mitigate dysglycemic/dyslipidemic burdens...

PURPOSE: Increased oxidative stress and impaired antioxidant defense are important mechanisms in the pathogenesis of diabetic myopathy. Since diabetes mellitus type 1 decreases muscle regeneration capacity the present study was designed to determine the influence of alpha-lipoic acid (ALA), a potent biological antioxidant, on the process of regeneration of diabetic rat skeletal muscles. METHODS: 40 Wistar rats were divided into three groups: control (n = 8), untreated diabetic group (n = 16) and ALA treated diabetic group (n = 16)...

Cichoric acid (CA), extracted from edible plants and vegetables, is a potential natural nutraceutical, with antioxidant and hypoglycaemic biological functions. The objective of this study was to explore the potential underlying molecular mechanisms involved in normalizing diabetes-related changes in hyperglycaemia via pancreas apoptosis and muscle injury induced by multiple low-dose STZ (MLD-STZ) injection in response to dietary supplementation with CA. To induce the MLD-STZ diabetic mice, the C57BL/6J mice were intraperitoneally injected with STZ (50 mg/kg body weight) for consecutive five days...

Proteinuric renal disease is prevalent in congenital or acquired forms of generalized lipodystrophy. In contrast, an association between familial partial lipodystrophy (FPLD) and renal disease has been documented in very few cases. A 22-year-old female patient presented with impaired glucose tolerance, hyperinsulinemia, hirsutism and oligomenorrhea. On examination, there was partial loss of subcutaneous adipose tissue in the face, upper and lower limbs, bird-like facies with micrognathia and low set ears and mild acanthosis nigricans...

Mitochondrial dysfunction is associated with several clinical manifestations including diabetes mellitus (DM), neurological disorders, renal and hepatic diseases, and myopathy. Although mitochondrial dysfunction is associated with increased bone resorption and decreased bone formation in mouse models, effects of alterations in mitochondrial function on bone remodeling and mass have not been investigated in humans. We recruited 45 carriers (29 females, 16 males) with the m.3243A>G mutation and healthy controls matched for gender, age, height, and menopausal status...
