Rhabdomyolysis is a condition affecting body homeostasis that results from impaired supply of muscles with energy, nutritional factors and blood. Complex pathophysiological mechanism causes that extended myolysis may complicate different clinical conditions, such as: crush syndrome, excessive physical effort (work, seizures), toxic effect of drugs and toxins, water-electrolyte disturbances, congenital enzymatic deficiencies etc. It seems that on the cellular level, essential role is played by excessively high intracytoplasmatic calcium level, which affects metabolic processes. So high calcium level is a consequence of muscular cell injury irrespective to its reason. It manifests clinically as muscular weakness, pal and oedema and laboratory tests reveal elevated CK, GOT, GPT, aldolase and LDH levels as well as dark brown urine colour. Demonstration of elevated serum myoglobin level or its presence in urine directly confirms development of rhabdomyolysis. In unfavorable conditions, rhabdomyolysis may result in acute renal failure. Appropriately early and adequate water supply and alkalization plays an essential role in prevention of impairment in renal function. In advanced phase of renal failure, hemodialysis is a standard treatment.

A 64-year-old woman was admitted to our hospital because of muscle weakness and atrophy in the extremities. Four years before admission, he was noticed to have elevated creatine kinase (CK) level, but had no further evaluation. Two years later, she became difficult in standing up and needed a wheelchair. Six months before admission, she noticed muscle wasting in the buttock, thigh, bilateral forearms, and weakness in the upper limbs. On neurologic examination, she had weakness in sternocleidomastoid and all limb muscles, predominantly in the distal portion of the upper extremities. Laboratory study revealed elevated CK, LDH, and aldolase levels, and myogenic change with fibrillation on needle EMG. Muscle biopsy showed myopathic changes with infiltration of mononuclear cells and rimmed vacuoles. The clinical manifestations as well as poor response to corticosteroids therapy were supportive of the diagnosis of inclusion body myositis. However, the distribution of muscle weakness in her wrist, weaker in the extensors than in the flexors, was not characteristic to IBM. This problem was solved by the right forearm MRI which showed a high signal intensity area in flexor muscles, but not in extensors on T1 and T2 weighted images. Accordingly, the muscle MRI of forearm was a diagnostic aid of IBM in this patient.

Juvenile dermatomyositis (JDM) is characterized by microvasculopathy of the striated muscle, which indicates different etiology, clinical manifestation and prognosis from the adult-onset dermatomyositis. We experienced 10 cases of JDM and 1 case of juvenile polymyositis (JPM) in the recent 14 years, and analyzed clinical manifestation, laboratory findings, treatment anrognosis. The cases were 9 girls and 2 boys. The onset of the disease was 2 years of age in 2 patients, and 9 to 13 years of age in 9 patients. During the follow-up courses, no cases were dead or complicated with neoplasm. Skin rash was the most frequent manifestation at the onset, and facial erythema was common. Muscle weakness was observed only in 4 cases at the onset, and in all cases muscle enzymes including creatine kinase and aldolase were elevated. The clinical course was classified into three groups; monocyclic (5 cases), chronic and recurrent (4 cases), and fulminant (2 cases). Prognosis depended not on the degree of the elevated serum muscle enzymes, but on the initial therapy employed at the onset of the disease. Five cases including 2 cases of fulminant type were initially treated with methylprednisolon pulse therapy, and all of these had no recurrence. On the other hand, 6 cases were started the therapy with p.o. prednisolone. Four of them had frequent recurrences in accordance with tapering of prednisolone. These cases were effectively treated with the combination with immunosuppressants. In previous reports, JDM and JPM were reported to be a disorder which had relatively favorable prognosis. But we found that one third of the cases had chronic and recurrent courses. Methylprednisolone pulses as initial therapy may be effective in preventing the chronicity and recurrence of the disease.

A 22-year-old male with juvenile dermatomyositis presented with fever up to 40 degrees C and acute pain in his right thigh accompanied by muscle weakness, a skin rash and a tender swelling. Serum aspartate aminotransferase (AST) and aldolase were mildly elevated. C-reactive protein (CRP) and fibrinogen were markedly increased. The differential white blood cell count revealed relative lymphopenia. Radiography showed diffuse calcifications particularly around the thighs and knees of both legs. Magnetic resonance imaging (MRI) demonstrated inflammatory infiltrates in the right thigh. The lesions were identified as phlegmone by immunoszintigraphy with 99mTc-labelled antigranulocyte antibodies. On the 10th day of treatment Staphylococcus aureus was cultured from blood. Patients with juvenile dermatomyositis and calcinosis may develop bacterial infections of soft tissue which sometimes mimic a disease flare. For differential diagnosis plain radiographs, CT scans and MRI are of limited value. Immunoszintigraphy is able to differentiate between infiltrates caused by granulocytes and lymphocytes.

A 66-year-old female was admitted to our hospital in January, 1998, complaining of low grade fever and muscle weakness of her legs. Physical examination revealed muscle weakness of her neck (4/5) and proximal skeletal muscles of her bilateral legs (3/5-4/5). She showed proteinuria and microhematuria. Her serum levels of ureanitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, creatinekinase, aldolase and myoglobin were all within the normal ranges. Antinuclear antibodies were negative, but her serum levels of pANCA (743 EU) and C reactive protein (18.0 mg/dl) were elevated. Neuroconduction velocity of her left common peroneal nerve was decreased to 40.8 m/sec and electric myograph showed neurogenic changes. Magnetic resonance images (MRI) of her bilateral thigh depicted high signal intensity in quadriceps by T 2 weighed images, but the signals were not enhanced by gadolinium injection. Muscle and renal biopsies revealed necrotizing vasculitis of the small arteries. Crescentic glomerulonephritis was also observed by renal biopsy. These findings supported the diagnosis of microscopic PN. On 16 th admission day, she developed acute cardiac and respiratory failures due to cardiac and respiratory muscle involvements with PN, and was assisted by mechanical ventilation. She was treated with methylprednisolone pulse therapy (500 mg/day, three consecutive days) on 18 th admission day, followed by 40 mg of oral prednisolone daily. However, her symptoms deteriorated, and herserum creatinine levels increased to 2.4 mg/dl. On 24 th admission day, intravenous cyclophosphamide pulse therapy (500 mg/day) was instituted. Her cardiac wall motion on echocardiography and serum creatinine levels gradually improved, but her skeletal and respiratory muscle weakness did not improve. On 38 th admission day, she was complicated with respiratory infection by methicillin resistant Staphylococcus aures. On 62 th admission day, she died of endotoxic shock. This is the first report describing respiratory muscle involvement with PN, and the second report describing MRI findings of muscle involvement by PN. Therefore, our case provides important clinical information for the diagnosis and treatment of the disease.

Dermatomyositis (DM) is a rare inflammatory disorder of the skin and muscles associated with an increased incidence of malignancy. We describe herein the case of a 59-year-old woman with DM accompanied by rectal cancer. Following excision of the rectal cancer, the characteristic features of the skin rash such as the heliotrope eyelid rash and Gottron's papules, and proximal muscle weakness, improved. Moreover, the elevated preoperative serum levels of muscle-associated enzymes, including aspartate transaminase, creatine phosphokinase, lactate dehydrogenase, and aldolase, decreased from 38 to 16 (IU/1), 138 to 42 (IU/1), 672 to 515 (IU/1), and 32.2 to 4.3 (IU/1), respectively. The current concepts of the correlation between DM and malignancy are discussed with regard to the present case.

A 29-year-old male who had a past history of mild ECG abnormality of arrhythmia at the age of 14 years, was referred to our hospital because of elevated serum creatine kinase (CK) level. He had never been aware of muscular weakness nor cardiac symptoms. Neurological examination revealed normal muscle strength of all extremities except marked back muscle weakness. He had normal intelligence. On laboratory examination, serum AST, ALT, LDH, aldolase, CK and myoglobin levels were elevated. Both lactate and pyruvate levels were normally responded after an ischemic exercises test. Acid maltase activity was normal in white blood cells. A muscle biopsy obtained from rectus femoris muscle revealed vacuolar myopathy with mildly increased PAS positive material. On electron microscopy, there were autophagic vacuoles scavenging glycogen particles and cytoplasmic debris, and sarcolemmal indentation, compatible with the findings of lysosomal glycogen storage disease with normal acid maltase. This patient had unusual clinical features of absent mental retardation and no apparent cardiomyopathy. Accordingly, mental retardation is probably not necessary to see later onset of cardiac muscle involvement.

A 53-year-old female suffered from joint pain and muscle weakness in all extremities in 1991. Laboratory data showed increased creatine phosphokinase (CK) and aldolase. Liver dysfunction and weakness of proximal muscles also appeared and polymyositis (PM) was suspected. Two years later, she was diagnosed with dermatomyositis (DM) through skin and muscle biopsy. Because elevation of biliary enzymes and transaminases were continued, liver biopsy was performed in 1997. Histopathological findings of her liver were compatible with primary biliary cirrhosis (PBC). Similar conditions were noticed in her identical twin as well. DM associated with PBC is unusual and cases of monozygotic twins with both conditions are very rare. The difference between PBC and autoimmune cholangitis (AIC) which has recently reported and the genetic influence on the pathogenesis of DM and AIC are also discussed.

We report a 55-year-old woman with typical clinical, biochemical and radiological features of Cushing's disease, who developed a severe respiratory insufficiency as the main symptom. She also complained of proximal muscle weakness over the last year and progressive dyspnea over the last four months. Bronchospasm, respiratory infection or cardiologic dysfunction were excluded. Arterial blood gas analysis showed severe respiratory insufficiency with hypoxemia and hypercapnia, respiratory acidosis and a normal alveolar-arterial oxygen gradient. Spirometry and plethysmography showed a restrictive ventilatory failure and maximum inspiratory and expiratory pressures were reduced. These findings were strongly suggestive of neuromuscular disease. Serum creatine kinase, aldolase, sodium, potassium and thyroid function tests were normal. An electromyogram and a muscle biopsy confirmed myopathic disease. Ketoconazole therapy improved her symptoms and respiratory function tests. In conclusion although proximal myopathy is a frequent presenting symptom of Cushing's syndrome, involvement of respiratory muscles with severe restrictive ventilatory dysfunction has not been previously reported as the main initial feature of Cushing's disease. Medical treatment of hypercortisolism improves muscle strength and resolves the respiratory insufficiency.

Graft-versus-host disease (GVHD) remains a major complication of allogeneic hematopoietic stem cell transplantation. Polymyositis can occur in association with chronic GVHD and mimics the idiopathic form of the disease. We report two cases of chronic GVHD-associated polymyositis and review the published literature. The two patients presented 13 and 19 months after allogeneic transplantation with characteristic features of muscular hypotrophy, proximal muscle weakness, pain, elevated creatine phosphokinase (CPK), aldolase and SGPT. Interestingly, both patients had HLA DR52 genes, which is frequently reported in association with idiopathic polymyositis. Electromyogram (EMG) and muscle biopsy confirmed the diagnosis. Treatment with cyclosporine or tacrolimus resulted in complete and sustained remission of polymyositis in both cases. A review of the literature shows cyclosporine and steroids are well-described treatment options for patients with myositis in post transplant, as well as idiopathic cases. The duration of immunosuppressive treatment has varied in different reports, and there is a risk of recurrence when immunosuppression is tapered.
