Rhabdomyolysis is a process of muscle destruction that can present with varying clinical manifestations. In pediatric patients, its main etiology is infectious diseases. We present a previously healthy adolescent who was admitted to our emergency department with a four-day history of myalgia, muscle weakness and dark urine. At presentation, she was dehydrated. Blood analysis revealed acute rena...

Hypercatabolic syndrome (HS) is a biochemical state characterized by increased circulating catabolic hormones (eg, cortisol, catecholamines) and inflammatory cytokines (eg, tumor necrosis factors, interleukin-1beta), and decreased anabolic insulin effects with consequent insulin resistance. The most important metabolic consequence of HS is the skeletal and cardiac muscle protein breakdown that ...

Antisense oligonucleotide-mediated exon skipping is able to correct out-of-frame mutations in Duchenne muscular dystrophy and restore truncated yet functional dystrophins. However, its application is limited by low potency and inefficiency in systemic delivery, especially failure to restore dystrophin in heart. Here, we conjugate a phosphorodiamidate morpholino oligomer with a designed cell-pen...

This paper describes the case of a young man with progressive muscular dystrophy who had supraventricular arrhythmias and intractable congestive failure. Hemodynamic studies and left cineventriculographic findings were compatible with a diagnosis of severe left ventricular failure. Coronary cinearteriography showed an abrupt ending of the artery to the sino-atrial node. At necropsy, a noninflam...

We describe an infant with prenatally diagnosed muscular ventricular septal defect (VSD) and dilated cardiomyopathy with clinical deterioration despite escalating medical therapy in whom successful transcatheter muscular VSD closure was achieved eliminating need to pursue cardiac transplantation.

Mutations in several members of the dystrophin glycoprotein complex lead to skeletal and cardiomyopathies. Cardiac care for these muscular dystrophies consists of management of symptoms with standard heart medications after detection of reduced whole heart function. Recent evidence from both Duchenne muscular dystrophy patients and animal models suggests that myocardial dysfunction is present b...

This paper describes a neonate with type II Gaucher disease. The phenotype was unusually severe with congenital ichthyosis, hepatosplenomegaly, muscular hypotonia, myoclonus and respiratory failure. Electron microscopy of the skin revealed lamellar body contents in the stratum corneum interstices, appearances considered to be typical of type II Gaucher disease. The baby died from respiratory fa...

We present an adolescent with McArdle disease and recurrent acute kidney failure due to rhabdomyolysis. The patient was admitted with acute kidney failure for 3 times and due to a history of proximal weakness, fatigue, and muscular cramps after physical activities a glycogen-storage disease was suspected. Serum creatine phosphokinase and urine myoglobin were found to be elevated. McArdle diseas...
