Abstract
Background Statin-related skeletal muscle disorders range from benign myalgias – such as non-specific muscle aches or joint pains without elevated serum creatinine kinase (CK) concentration – to true myositis with >10-fold elevation of serum CK, to rhabdomyolysis and myoglobinuria. The genetic basis of statin-related muscle disorders is largely unknown. Because mutations in the COQ2 gene are associated with severe inherited myopathy, we hypothesized that common, mild genetic variation in COQ2 would be associated with inter-individual variation in statin intolerance. We studied 133 subjects who developed myopathy on statin monotherapy and 158 matched controls who tolerated statins without incident or complaint. Results COQ2 genotypes, based on two single nucleotide polymorphisms (SNP1 and SNP2) and a 2-SNP haplotype, all showed significant associations with statin intolerance. Specifically, the odds ratios (with 95% confidence intervals) for increased risk of statin intolerance among homozygotes for the rare alleles were 2.42 (0.99 to 5.89), 2.33 (1.13 to 4.81) and 2.58 (1.26 to 5.28) for SNP1 and SNP2 genotypes, and the 2-SNP haplotype, respectively. Conclusion These preliminary pharmacogenetic results, if confirmed, are consistent with the idea that statin intolerance which is manifested primarily through muscle symptoms is associated with genomic variation in COQ2 and thus perhaps with the CoQ10 pathway.

Abstract
Drug-induced diseases constitute up to 5% of hospital admissions,a figure which almost certainly understates the total morbidity due to drugs1. Sever drug-induced myopathies are uncommon, but milder forms may be more prevalent than is generally appreciated, since skeletal muscle constitutes some 45% of total body-weight and has a major metabolic role in addition to its mechanical function2. Knowledge of possible effects of drugs on the neuromuscular system is of increasing importance both because the range of therapeutic agents continues to expand and because the resulting syndromes, through usually reversible at the outset, may progress and lead to grave consequences if the drug responsible is not stopped. Drug-induced neuropathies3 will not be considered here, but it will be appreciated that muscle weakness may also be feature of such disorders and that some drugs may cause both a neuropathy and a myopathy. The features of the main drug-induced syndromes are summarised in the table. To these one could justifiably add the unwanted effects of srugs given for the treatment of central-nervous-system or neuromuscular disorders per se-e.g., the cholinergic block which may be produced by anticholinesterases alone or with corticosteroids in the myasthenic,4 and the profound weakness which may supervene after relief of spasticity with dantrolene sodium5.

Abstract
UNLABELLED This study assessed the impacts of iron, heme oxygenase (HO), hydroxyl radical (.OH), and glutathione (GSH) on the initiation phase of myohemoglobinuric proximal tubular injury using a novel model system. Rhabdomyolysis was induced in rats by glycerol injection and four hours later proximal tubular segments (PTS) were isolated. They were incubated for 0 to 90 minutes either in the presence or absence of an iron chelator (deferoxamine; DFO), .OH scavengers, an .OH trapping agent (salicylate; to gauge .OH production), GSH, or catalase. In selected experiments, an HO inhibitor (Sn protoporphyrin) was given at the time of glycerol injection to assess HO's acute effects on the evolving injury. Cell death and lipid peroxidation were quantified by % LDH release and malondialdehyde (MDA) generation, respectively. PTS from normal rats served as controls. Post-glycerol PTS manifested progressive LDH release (47 +/- 2%) and 20-fold MDA increments during the incubations, whereas only 11 +/- 1% LDH release and no MDA generation was observed in the normal PTS. DFO completely prevented both parameters of glycerol-induced injury. HO inhibition exerted an acute protective effect, despite previous in vivo data suggesting that HO is a cytoprotectant. Neither .OH scavengers nor catalase mitigated post-glycerol injury, the latter correlating with reduced, not increased, .OH production. GSH slightly decreased LDH release while causing a paradoxical threefold MDA increment. The latter was iron dependent (blocked by DFO), was expressed in normal PTS, and it could be reproduced by equimolar cysteine. That GSH increased iron-dependent lipid peroxidation in a cell free system (exogenous phosphatidylcholine) indicated that GSH metabolism to cysteine was not a requirement for this reaction. IN CONCLUSION (1) chelatable iron can fully account for heme protein-triggered proximal tubular injury; (2) HO contributes to this injury, presumably by causing iron release; (3) the heme-induced injury appears to be mediated by non-.OH oxidizing intermediates; (4) GSH can exert both anti- and pro-oxidant effects; and (5) i.m. glycerol injection, followed by proximal tubular isolation, represents a new and highly useful model for studying direct determinants of heme protein cytotoxicity.

Abstract
Five patients who had injected intravenous (i.v.) phenmetrazine or methamphetamine developed marked prostration resembling septic shock, disseminated intravascular coagulation, rhabdomyolysis with myoglobinuria, and azotemia. Soon after injection, four noted chills, fever, sweats, nausea, and abdominal cramps. Within hours, they developed vomiting, myalgias, paresthesias, headache, and orthostasis. Cardiorespiratory arrest, accelerated bleeding, and noncardiac pulmonary edema were observed in one patient. From 4 to 11 litres of saline were required in the first 24 h to maintain blood pressure and urine output, suggesting that shock resulted from massive loss of intravascular volume into necrotic muscle. Recognition of this syndrome and treatment by aggressive volume replacement led to the recovery of all five patients.

Abstract
Strychnine poisoning results in a predictable and treatable sequence of events involving blockade of the inhibitory neurotransmitter, extensor muscle spasms, seizures, and respiratory paralysis. These spasms may lead to hyperthermia, profound lactic acidosis, and rhabdomyolysis. Acidosis is primarily attributable to lactate, as indicated by the correlation between arterial pH and log of lactic acid concentration (r = -0.878). Interruption of the strychnine blockade is the primary therapy for strychnine poisoning. Phenobarbital in moderate doses should be the first intervention and anesthetic doses should be used if necessary. Suppression of convulsions will permit successful management of the complications of strychnine poisoning. Our patient survived, even though at one point he had a pH of 6.55, a lactate level of 32 mM/liter, a temperature of 43 degrees C, and rhabdomyolysis with an increased creatine phosphokinase level of 359,000 mU/ml (5,983 mumol/s/liter).

Abstract
This paper systematically reviews the clinical evidence relating to the safety of extracts of the herbal anxiolytic kava (Piper methysticum). Literature searches were conducted in four electronic databases and the reference lists of all papers located were checked for further relevant publications. Information was also sought from the spontaneous reporting schemes of the WHO and national drug safety bodies and ten manufacturers of kava preparations were contacted. Data from short-term post-marketing surveillance studies and clinical trials suggest that adverse events are, in general, rare, mild and reversible. However, published case reports indicate that serious adverse events are possible including dermatological reactions, neurological complications and, of greatest concern, liver damage. Spontaneous reporting schemes also suggest that the most common adverse events are mild, but that serious ones occur. Controlled trials suggest that kava extracts do not impair cognitive performance and vigilance or potentiate the effects of central nervous system depressants. However, a possible interaction with benzodiazepines has been reported. It is concluded that when taken as a short-term monotherapy at recommended doses, kava extracts appear to be well tolerated by most users. Serious adverse events have been reported and further research is required to determine the nature and frequency of such events.

Abstract
Phencyclidine (PCP) is a dissociative veterinary anesthetic and tranquilizer that at present is being abused as a psychedelic and hallucinogenic agent with increasing frequency. The cases of two young patients suffering from phencyclidine toxicity are reported. In each, central nervous system depression was accompanied by an acute dystonic motor reaction resulting in acute rhabdomyolysis and myoglobinuria. Skeletal muscle injury was felt to be the result of excessive involuntary isometrimc motor activity rather than a direct effect of phencyclidine on skeletal muscle. Patients suffering from phencyclidine intoxication should be screened for acute rhabdomyolysis. Phencyclidine intoxication should be included in the differential of nontraumatic rhabdomyolysis and should be considered among the potential causes of acute myoglobinuric renal failure.

Abstract
Two paediatric cases are reported in which unexpected, life-threatening arrhythmias occurred. Routine induction of general anaesthesia with thiopentone, 5 mg.kg-1, in one and with halothane in the other, and succinylcholine 1.25-1.5 mg.kg-1 i.v. was followed by the development of wide complex tachyarrhythmia with hypotension in the first case and asystole in the second case despite pre-treatment with atropine in both cases. The first patient was resuscitated with tracheal intubation, 100% oxygen, manual ventilation and intravenous lidocaine and bicarbonate. The second patient required intubation, manual ventilation, 12 min of CPR and i.v. calcium, epinephrine and bicarbonate, as well as DC counter shock. Neither patient received dantrolene. Early recovery in both patients was uneventful with no neurological sequelae. Subsequent investigations revealed the presence of a dystrophin-deficient muscular dystrophy, Duchenne muscular dystrophy and Becker muscular dystrophy respectively, previously unsuspected, in both patients. The aetiology of the observed arrhythmias was presumably hyperkalaemia, secondary to succinylcholine-induced rhabdomyolysis. It is suggested that when faced with sudden, life-threatening arrhythmias following succinylcholine at induction of anaesthesia for paediatric patients, clinicians should include occult myopathy in the differential diagnosis, and thus consider the aggressive management of hyperkalaemia in addition to basic resuscitative efforts.

Abstract
Acute tubular cell injury is accompanied by plasma membrane phospholipid breakdown. Although cholesterol is a dominant membrane lipid which interdigitates with, and impacts, phospholipid homeostasis, its fate during the induction and recovery phases of acute renal failure (ARF) has remained ill defined. The present study was performed to ascertain whether altered cholesterol expression is a hallmark of evolving tubular damage. Using gas chromatographic analysis, free cholesterol (FC) and esterified cholesterol (CE) were quantified in: 1) isolated mouse proximal tubule segments (PTS) after 30 minutes of hypoxic or oxidant (ferrous ammonium sulfate) injury; 2) cultured proximal tubule (HK-2) cells after 4 or 18 hours of either ATP depletion/Ca(2+) ionophore- or ferrous ammonium sulfate-mediated injury; and 3) in renal cortex 18 hours after induction of glycerol-induced myoglobinuric ARF, a time corresponding to the so-called "acquired cytoresistance" state (ie, resistance to further renal damage). Hypoxic and oxidant injury each induced approximately 33% decrements in CE (but not FC) levels in PTS, corresponding with lethal cell injury ( approximately 50 to 60% LDH release). When comparable CE declines were induced in normal PTS by exogenous cholesterol esterase treatment, proportionate lethal cell injury resulted. During models of slowly evolving HK-2 cell injury, progressive CE increments occurred: these were first noted at 4 hours, and reached approximately 600% by 18 hours. In vivo myoglobinuric ARF produced comparable renal cortical CE (and to a lesser extent FC) increments. Renal CE accumulation strikingly correlated with the severity of ARF (eg, blood urea nitrogen versus CE; r, 0.84). Mevastatin blocked cholesterol accumulation in injured HK-2 cells, indicating de novo synthesis was responsible. Acute tubule injury first lowers, then raises, tubule cholesterol content. Based on previous observations that cholesterol has cytoprotectant properties, the present findings have potential relevance for both the induction and maintenance phases of ARF.

Abstract
1. Muscle injury (rhabdomyolysis) is one of the causes of acute renal failure (ARF). Iron, free radicals and nitric oxide (NO) play a critical role in the pathogenesis of glycerol-induced myoglobinuric ARF. L-Carnitine is an anti-oxidant and prevents the accumulation of end-products of lipid peroxidation. Therefore, the aim of the present study was to investigate the effects of L-carnitine on myoglobinuric ARF induced by intramuscular (i.m.) hypertonic glycerol injection. 2. Sprague-Dawley rats were divided into three groups. Rats in group 1 (n = 8) were given saline, whereas those in groups 2 (n = 10) and 3 (n = 10) were injected with glycerol (10 mL/kg, i.m.). Concomitant with and 24 h after glycerol injection, L-carnitine (200 mg/kg, i.p.) was administered to group 3 rats. Forty-eight hours after glycerol injection, blood samples and kidney tissues were taken from anaesthetised rats. 3. Plasma creatine kinase (CK) activity, urea, creatinine and NO levels, as well as kidney tissue superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) enzyme activity and malondialdehyde (MDA) and glutathione (GSH) levels, were determined. In the kidney tissue, histopathological changes and iron accumulation in the tubular epithelium were also investigated. 4. Glycerol treatment caused severe ARF: a marked renal oxidative stress, significantly increased CK activity, urea and creatinine levels and decreased plasma NO levels. Histopathological findings in group 2 rats confirmed that there was renal impairment by cast formation and tubular necrosis and a marked increase in iron accumulation in the tubular epithelium. All these factors were significantly improved by L-carnitine supplementation. 5. These results may indicate that L-carnitine treatment protects against functional, biochemical and morphological damage and iron accumulation in glycerol-induced myoglobinuric ARF in rats. In this model, the protective effect of L-carnitine treatment may provide a new insight into the treatment of rhabdomyolysis-related ARF.

Abstract
We report a patient with Duchenne muscular dystrophy who developed malignant hyperpyrexia during general anaesthesia. During anaesthesia bradycardia was followed by ventricular fibrillation, on which ventricular flutter supervened and a body temperature rise of 0.6 degrees C for 15 minutes, myoglobinuria and elevation of CPK level were observed. The caffeine sensitivity test of biopsied muscle fibers revealed an increase in sensitivity, although there was no sign of muscle rigidity during or after anaesthesia. Diagnosis of Duchenne muscular dystrophy was first established after the development of malignant hyperpyrexia in the present case as well as in previously reported cases. Determination of serum CPK is very important before general anaesthesia.

Abstract
Renal cortical blood flow of rats with postischemic, myohemoglobinuric, and mercury-induced acute renal failure was measured by the hydrogen washout technique using implanted platinum electrodes. Total renal blood flow was determined by venous cannulation in separate series of rats. The values obtained with the two methods were in excellent qualitative agreement (r=0.99, P less than 0.001), although venous cannulation gave values that were constantly lower than those calculated for whole kidney from the cortical flow rate and assumed cortical mass. Myohemoglobinuria produced by glycerol injection caused cortical blood flow to fall from a control value of 7.37+/-0.23 (SEM) ml/min X g of cortex to approximately one-half that value for four hours after injection (P less than 0.001). Flow rates 12 and 24 hr after glycerol injection were 85% (P less than 0.001) and 90% (P less than 0.05) of control, respectively. Cortical flow was reduced to 5.49+/-0.39 (SEM) ml/min X g of cortex four hours after release of one hour's total bilateral renal arterial occlusion (P less than 0.001), but rose to normal within 24 hr. Poisoning with 4.7 mg/kg of body wt of mercuric chloride produced a cortical blood flow value that was 30% higher than control 24 hr after injection (P less than 0.01), while a 12 mg/kg of body wt dose gave a normal flow value. Inulin clearance was severely depressed in all models at all study times. Thus, in contrast to human acute renal failure, marked renal cortical ischemia is not an essential feature of these different forms of murine acute renal failure.

Abstract
Rhabdomyolysis occurred in 25 of 1,000 patients (2.5%) with phencyclidine (PCP) intoxication. 10 of these 25 patients (40%) developed acute renal failure and another 7 had mild impairment in renal function. Marked hyperuricemia was present in all 17 patients, and marked hyperphosphatemia and hypocalcemia were noted in the 10 patients with acute renal failure; 3 of the latter developed hypercalcemia during the diuretic phase of the illness. Fever, tachycardia and hypertension were frequent findings among the 25 patients with rhabdomyolysis and all had leukocytosis. The data show that rhabdomyolysis with and without acute renal failure is not infrequent among abusers of PCP.

Abstract
A 74-year-old male was admitted to hospital with acute rhabdomyolysis and myoglobinuria due to hypokalemia. The hypokalemia resulted from diuretic treatment. He had no family history of myopathy, and no diarrhea and vomiting. The neurological examination revealed painful quadriplegia. The blood pressure was 160/74 mm Hg. Laboratory examination showed hypokalemic and hypochloremic metabolic alkalosis (serum K 1.5 mEq/l, serum Cl 89 mEq/l, base excess + 20.9, HCO3- 44.9 mmol/l, pH 7.563) and marked elevations of serum CPK, LDH, GOT, GPT and myoglobin. Endocrinological and renal functions were normal. Muscle biopsy revealed marked necrosis with remarkable phagocytosis and vacuolar degeneration. The cessation of diuretics and intravenous infusion of potassium chloride resulted in a marked improvement in clinical and laboratory findings. The diuretics-induced hypokalemic myopathy is rare in the literature.

Abstract
PURPOSE To present a case of rhabdomyolysis which developed in a child with a known history of Duchenne's muscular dystrophy, following an anesthetic which included sevoflurane. CLINICAL FEATURES An 11 yr old boy with a known history of Duchenne's muscular dystrophy underwent anesthesia for strabismus repair. The anesthetic consisted of sevoflurane and nitrous oxide without the use of a muscle relaxant. His postoperative course was complicated by a complaint of heel pain and the development of myoglobinuria. He was treated with dantrolene sodium and discharged home after two days, without further complication. CONCLUSION Sevoflurane anesthesia has not been shown previously to be associated with the development of acute rhabdomyolysis in a child with a history of Duchenne's muscular dystrophy. As with halothane and isoflurane, the continued use of sevoflurane in the presence of Duchenne's muscular dystrophy should be questioned.

Abstract
A number of studies support, and others fail to support, the concept that the renin-angiotensin system plays a key role in the pathogenesis of acute renal failure. This study, employing active and passive immunization against angiotensin II, was designed to examine the primacy of circulating angiotensin as a mediator of this syndrome. Neither mode of immunization significantly affected the degree of azotemia or the marked reduction of inulin clearance expected in rats subjected to glycerol-induced myohemoglobinuria. Twenty-four hours after challenge, inulin clearance (Cin) in actively immunized rats fell to 3.2% of control and that of unimmunized rats given the same dose of glycerol was 2.5% of control. Although there was some variation among groups of passively immunized rats, Cin of one group being 18% of control, Cin of the other groups was less than 3% of control. The dose and binding capacity of the immune globulin used here were essentially the same as those reported in another study in which immunization was thought to be of prophylactic value in rats subjected to s.c. administered glycerol injections. Technologic differences unrelated to immunization are suggested to have caused the difference in results in the two studies, and it seems doubtful that circulating angiotensin plays a key role in the pathogenesis of myohemoglobinuric acute renal failure in the rat.

Abstract
A patient had hyperthermia, rhabdomyolysis, and myoglobinuric renal failure after the recreational use of cocaine. We attribute this to the pyrogenic properties of cocaine and environmental factors. The use of cocaine during summer months or in areas with high ambient temperatures should alert physicians to the development of hyperthermia with or without seizures. Prompt recognition of the ensuing complications including mixed metabolic acidosis, rhabdomyolysis, and renal failure can result in appropriate and effective treatment.
