Among active component service members in 2016, there were 525 incident diagnoses of rhabdomyolysis likely due to physical exertion and/or heat stress ("exertional rhabdomyolysis"). The crude incidence rate in 2016 was 40.7 cases per 100,000 person-years. Annual rates of incident diagnoses of exertional rhabdomyolysis increased 46.2% between 2013 and 2016, with the greatest percentage change occurring between 2014 and 2015. In 2016, relative to their respective counterparts, the highest incidence rates of exertional rhabdomyolysis affected service members who were male; younger than 20 years of age; and black, non-Hispanic...

Rhabdomyolysis is a disorder characterized by acute damage of the sarcolemma of the skeletal muscle leading to release of potentially toxic muscle cell components into the circulation, most notably creatine phosphokinase (CK) and myoglobulin, and is frequently accompanied by myoglobinuria. In the present work, we evaluated the toxicity of p-phenylenediamine (PPD), a main component of hair dyes which is reported to induce rhabdomyolysis. We studied the metabolic effect of this compound in vivo with Wistar rats and in vitro with C2C12 muscle cells...

Mitochondrial diseases exhibit significant clinical and genetic heterogeneity. Mitochondria are highly dynamic organelles that are the major contributor of adenosine triphosphate, through oxidative phosphorylation. These disorders may be developed at any age, with isolated or multiple system involvement, and in any pattern of inheritance. Defects in the mitochondrial respiratory chain impair energy production and almost invariably involve skeletal muscle and peripheral nerves, causing exercise intolerance, cramps, recurrent myoglobinuria, or fixed weakness, which often affects extraocular muscles and results in droopy eyelids (ptosis), progressive external ophthalmoplegia, peripheral ataxia, and peripheral polyneuropathy...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging febrile illness. While many kinds of severe complications including acute renal failure have been reported, rhabdomyolysis is rarely reported in association with SFTS. A 54-year-old female farmer was admitted with fever and diffuse myalgia. Laboratory finding showed thrombocytopenia, leukopenia, azotemia, extremely elevated muscle enzyme levels and myoglobinuria. We describe a fatal case of rhabdomyolysis with acute renal failure complicated by SFTS...

Thigh compartment syndrome (TCS) is a rare condition caused by high pressures within the fascial compartments of the thigh, impeding capillary flow and leading to decreased perfusion, tissue hypoxia, and necrosis. TCS is most frequently associated with trauma and anticoagulation but has also rarely been associated with exercise-related injury. We present the case of a 19-year-old female who reported painful swelling in her thighs and darkening of her urine after participating in a spinning class. On physical examination, the patient was found to have tight, painful thigh compartments with extreme tenderness on passive motion...

A primiparous pregnant woman in remission of myositis suffered very acute-onset ritodrine-induced rhabdomyolysis. At 29 gestational weeks, ritodrine was administered for threatened preterm labor. Just 3 h later, she complained of severe limb muscle pain, with serum creatinine phosphokinase elevated to 32 019 U/L and myoglobinuria. The muscle pain disappeared immediately after ceasing administration of ritodrine. At 31 weeks, premature rupture of the membranes occurred, necessitating cesarean section, yielding a baby with weak tonus, and the presence of infantile muscle diseases was suspected...

Exertional rhabdomyolysis is characterised by muscle breakdown associated with strenuous exercise or normal exercise under extreme circumstances. Key features are severe muscle pain and sudden transient elevation of serum creatine kinase (CK) levels with or without associated myoglobinuria. Mild cases may remain unnoticed or undiagnosed. Exertional rhabdomyolysis is well described among athletes and military personnel, but may occur in anybody exposed to unaccustomed exercise. In contrast, exertional rhabdomyolysis may be the first manifestation of a genetic muscle disease that lowers the exercise threshold for developing muscle breakdown...

INTRODUCTION: India is a land of culture and heritage always known for its rituals. The devotees offer their prayers in the form of fasting, sacrifices and many other difficult ways to please Almighty! While doing so they often endanger their lives. Rhabdomyolysis, in a particular group of devotees of Bihar/Jharkhand known as Dak-Bum, is a life-threatening clinical entity which occurs in these devotees who travel a long distance in a short period in a fasting state. Rhabdomyolysis detected by myoglobinuria can lead to acute kidney injury and mortality...

Malignant hyperthermia is a hypermetabolic syndrome that appears in susceptible patients after exposure to certain anaesthetic drugs (succinylcholine, inhalation anaesthetics). Its incidence in Spain is 1 in 40,000 adults, with a 10% mortality rate. It is induced by an abnormal regulation of the ryanodine receptors, producing a massive release of calcium from the sarcoplasmic reticulum in the striate muscle. Clinical manifestations include: CO2 increase, tachycardia, haemodynamic instability, metabolic and respiratory acidosis, profuse sweating, hyperpyrexia, CPK increase, myoglobinuria, kidney failure, disseminated intravascular coagulation (DIC), and ending in cardiac arrest...

Phosphoglycerate mutase enzyme deficiency in muscle causes a metabolic myopathy (glycogen storage disease X) characterized by exertional muscle contractures, weakness, hyperCKemia, and myoglobinuria. Six different autosomal recessive variants in PGAM-M have been described thus far (Salameh et al., 2013). In this case report, we report a novel disease-causing variant. A 52-year-old African-American woman presented with exertional muscle contractures, myalgias, and weakness since childhood including an episode of rhabdomyolysis...

BACKGROUND: Exertional rhabdomyolysis (ER) is the breakdown of skeletal muscle tissue following intense physical activity that results in impairment of the cell membrane, which allows intracellular contents to be released into the bloodstream. Signs and symptoms include myalgia, myoglobinuria and increased creatine kinase (CK) levels. Athletes are vulnerable to this condition due to their increased level of physical activity. The severity and effects of this condition vary between individuals; however, all athletes are at risk of significant muscle damage, renal failure and perhaps death if not recognized and treated quickly...

Heat strain is a potential risk factor for racing greyhounds in hot climates. However, there have been limited studies into the incidence of heat strain (when excess heat causes physiological or pathological effects) in racing greyhounds. The aim of this study was to determine if heat strain occurs in racing greyhounds, and, if so, whether environmental factors (e.g., ambient temperature and relative humidity) or dog-related factors (e.g., sex, bodyweight, color) are associated with the risk of heat strain...

INTRODUCTION: The sarcoglycanopathies are a heterogeneous group of autosomal recessive limb-girdle muscular dystrophies that cause varying degrees of progressive proximal muscle weakness. METHODS: We describe the case of a Caucasian girl who presented with exercise intolerance, myalgia, and dark urine. Onset of symptoms was at age 4, and she had myalgia with physical activity throughout childhood. Creatine kinase levels were as high as 18,000. RESULTS: Immunostaining of a muscle biopsy showed mildly diminished alpha sarcoglycan staining, and SGCA gene sequencing revealed n...

McArdle's disease is the most common metabolic myopathy of muscle carbohydrate metabolism, due to deficiency of myophosphorylase and alteration of glycogen breakdown in muscle. The clinical manifestations usually begin in young adulthood, with exercise intolerance, exercise-induced muscle cramps, pain and recurrent episodes of myoglobinuria. Many patients experience the second wind phenomenon, characterized by an improved tolerance for aerobic exercise approximately after eight minutes of motor activity, secondary to the increased availability of blood glucose and free fatty acids associated to an enhanced glucose uptake by muscle cells...
