Eight hours following tympanoplasty performed under general anaesthesia (sodium pentothal and trichloroethylene), a 30 year old male complained of muscular weakness and dark coloured urine. Urinalysis revealed myoglobin pigment. A rise in BUN (47mg%), serum creatinine (5.7mg%), creatinine phosphokinase (15,500 U/L) and CPK-MB fraction (4690 U/L) was noticed 36 hrs later. The patient developed acute renal failure, and recovered after haemodialysis. From a history of use of succinylcholine as a muscle relaxant during operation, myoglobinuria appears to be secondary to muscle damage caused by succinylcholine.

We reported two cases of acute alcoholic myopathy associated with rhabdomyolysis. The first case was 62 year-old man, who had been drinking every day for 40 years. Following diarrhea, he had psychic symptoms, and was admitted to our hospital. He was in a state of delirium. Tremor in extremities, dysarthria and weakness of lower extremities were observed. Neither swelling nor grasping pain were seen in any muscles. Laboratory data showed severe hypokalemia and high levels of serum muscle enzymes and myoglobin. An increase of lactate and pyruvate was not seen in ischemic exercise test performed at the acute or the recovery phase. It was suggested that glycolysis in muscles was suppressed in this case. The second case was 43 year-old man, who had been drinking every day for 27 years. Rapidly progressive weakness of both lower extremities was seen, and he was admitted to our hospital. Grasping pain of both legs and proximal muscle weakness of extremities were observed. Laboratory date showed normokalemia and high levels of serum muscle enzymes and myoglobin. Muscle biopsy showed no abnormal findings in histology and electron microscopy. Although the pathogenesis of acute alcoholic myopathy is unknown, suppression of muscle glycolysis enzyme caused by ethanol may play an important role in the first case.

A case of deletion of the short arm of chromosome 18 (18p- syndrome) associated with chronic polymyositis is described. The patient was a 37-year-old woman, who had psychomotor retardation in her early childhood. She started to notice a difficulty in raising both arms at 14 years of age and furthermore, she developed a gait disturbance due to weakness of the proximal muscles of the lower extremities from 34 years of age. Her parents were first cousins. On physical examination, she showed many dysmorphic features, such as short stature, round face, hypertelorism, low nasal bridge, small chin, high arched palate, abnormal dentition, short and webbed neck, and broad chest. Neurological examination revealed a low intelligence (IQ 47), severe proximal muscle weakness with moderate proximal muscle atrophy in all extremities, a waddling gait, and decreased or absent deep tendon reflexes of all extremities except for bilateral ankle jerks. Serum creatine kinase and myoglobin levels were slightly elevated. Needle EMG study showed fibrillation potentials at rest and polyphasic and low amplitude motor unit potentials of short duration on volitional activity in the affected muscles. Muscle biopsy demonstrated a variation in fiber size, necrotic fibers and mononuclear cell infiltration. These findings were compatible with those of chronic polymyositis. In addition, cytogenetic findings revealed 46.XX.18p- karyotype, although her parents had no chromosome abnormality. She had no immunological abnormality except for a positive rheumatoid factor and elevation of CD4/CD8 ratio on lymphocyte subset analysis in peripheral blood.(ABSTRACT TRUNCATED AT 250 WORDS)

Ten cases of acute renal failure (ARF) were seen in the period from July 1990 to August 1991 in the Nephrology Department of the SIMS Hospital, Srinagar. All were males in the age group of 18-28 years and in apparent good health when apprehended by the police. There was alleged history of physical torture of different types. All had been beaten on the buttocks, back and limbs; in addition, 2 cases had been given repeated electric shocks and 1 case put to 'sit-and-stand' exercise for about 3 h. The interval between the first day of torture till they came to our observation varied from 4 to 11 days. The main clinical features at the time of presentation were generalized aches and weakness (10), oligoanuria (9), vomiting (8), hypertension (6), acidosis (10), facial puffiness and pedal edema (6), fever and shivering (3), pulmonary edema (2), stupor (4), and hyperkalemia (5). All the cases had an established ARF (serum creatinine 668-1,997 mumol/l and serum urea 21.8-71.8 mmol/l) when first seen. Muscle enzymes, creatine phosphokinase, lactic dehydrogenase and serum glutamic oxaloacetic transaminase were all significantly raised indicating rhabdomyolysis. All showed evidence of myoglobin casts in urine. Nine had oliguric and 1 had nonoliguric ARF. All except the 1 case with nonoliguric ARF were managed with peritoneal dialysis and/or hemodialysis. All recovered. Early recognition of ARF is important since the main attention in such cases is directed towards the surgical aspect.

A 73-year-old man with alcoholic liver cirrhosis was admitted to our hospital because of massive hematemesis. He was treated with continuous intravenous infusion of vasopressin of 0.2 U/min. 22 hours after the infusion, he complained of myalgia, muscle weakness and skin mottling in the extremities. The skin lesion extended to the back. The serum CK and myoglobin levels were elevated to 52,280 IU/L and 84,400 ng/ml respectively. The urinary myoglobin level was elevated to 732,000 ng/ml. On the fifth hospital, he died of bleeding from the esophageal varices. Autopsy examination demonstrated necrosis of the skeletal muscle cells and myoglobin casts in the renal tubules. Our patient was probably hypersensitive to vasopressin because of underlying liver dysfunction. The massive myonecrosis might be induced from the following conditions; overreactive vasopressin-induced vasoconstriction resulted in ischemic muscle damage, and hypersensitive sarcoplasmic reticulum released excessive Ca2+ followed by muscle hypercontraction as seen in malignant syndrome or malignant hyperthermia.

A case is described in which, after administration of diclofenac for 13 days for arthritis attributed to gout, the patient experienced erythema multiforme followed by muscle weakness, elevation of serum creatine phosphokinase (CPK) level from 101 to 83,770 U/L, 100% muscle isoenzyme, blood urea nitrogen (BUN) level from 15 to 87 mg/dL, creatinine level from 1.0 to 2.1 mg/dL and urine myoglobin level to 1,190 micrograms/dL (N < 1.2). The diagnosis was rhabdomyolysis due to diclofenac, with myoglobinuria resulting in mild renal failure. Treatment consisted of discontinuing diclofenac and administering sufficient fluids to prevent progression of myoglobinuric renal failure. Serum CPK level gradually returned to normal by day 50, BUN and creatinine levels by day 28, and muscle strength between day 90 and 180. Rhabdomyolysis due to diclofenac or to other nonsteroidal antiinflammatory drugs has not been reported.

We report a case of dermatomyositis (DM) in a 15-year-old female with toxoplasmosis after ingestion of raw bovine liver. Facial erythema and cervical lymphadenopathy preceded myalgia and muscle weakness of the extremities. The diagnostic criteria of DM was fulfilled because of symmetrical and proximal dominant muscle weakness, elevation of myogenic enzyme (CPK, GOT, LDH, myoglobin, aldorase), myogenic pattern of electromyogram, skeletal muscle biopsy showing interstitial myositis with mild destruction of muscle fiber, and facial erythema. Immunological findings showed IgG anti-toxoplasma antibody to be 1340 IU/ml and IgM to be 7.0 (Cut off index 0.7), suggesting acute toxoplasmosis. Treatment with prednisolone for DM and acetylspiramycin for toxoplasmosis was successful. Toxoplasmosis should be considered as a possibility in patients with myositis.

Oral L-carnitine has been reported to lower the elevated serum myoglobin of renal failure in chronic peritoneal dialysis patients, and intravenous L-carnitine can improve muscle fatigue and cramps in chronic hemodialysis patients. In this study oral L-carnitine, 1.98 g/day, was administered to 6 chronic hemodialysis patients for 8 weeks. Serum levels of myoglobin, creatine kinase, and aldolase, as well as skeletal muscle symptoms (cramps during dialysis, fatigue, and weakness) were monitored biweekly for 12 weeks. Mean baseline serum myoglobin level was 337 +/- 34 ng/mL. By 6 and 8 weeks mean serum myoglobin was 234 +/- 39 and 233 +/- 40 ng/mL, significantly lower by the Friedman test (p < 0.05). Four weeks after carnitine was discontinued, mean serum myoglobin had risen to 320 +/- 118 ng/mL. Serum creatine kinase and aldolase levels were normal throughout the study. All 6 patients noted improvement in muscular symptoms, with maximal effect at 8 weeks, although 2 patients did not improve until 2 to 4 weeks after carnitine was stopped. We conclude that oral L-carnitine may lower serum myoglobin and improve muscle cramps and weakness in hemodialysis patients. The maximal effect of carnitine on myoglobin occurs 2 weeks before the maximal improvement in muscular symptoms.

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 38-year-old Japanese male who had traveled in China from September 13 to October 5, 1997, developed fever and severe conjunctivitis from October 20. After he was hospitalized in Kyoto City Hospital for persistent high fever on October 29, he developed muscular weakness and dysphagia which continued for two weeks. An electromyogram showed a myogenic pattern, and laboratory findings showed significant elevation of serum enzyme levels of muscle origin: CPK, 3,095 IU/l; aldorase, 195 IU/l; myoglobin, 7,570 ng/ml, and myoglobinuria, 94,700 ng/ml. The WBC was 10,800/microliter with 45% eosinophils. Muscular biopsy showed degeneration of muscle fibers with infiltration of macrophages and lymphocytes. On further inquiry, it was revealed that the patient had eaten smoked bear meat in China on September 30, three weeks prior to the onset of symptoms. A dot-ELISA serologic test for parasites was positive for Trichinella. Further, a coiled 1.2 mm long Trichinella larve was recovered from approximately 100 mg of frozen biopsied muscle by an enzyme digestion method. Mebendazole was given to the patient at a dosage of 200 mg/day for seven days. CPK levels were normalized within 3 days of the beginning of the treatment, and he was discharged without any symptoms. Physicians must be aware of trichinellosis and should include it in their differential diagnosis when examining patients with myositis and eosinophilia of unknown origin.
