The Authors make a list of 17 cases of elevation of total CPK (creatine phosphokinase) in subjects with vomiting of different cause, supposing the exclusion of more kinowed causes be able to stir up the enzyme increase. The Authors place the above mentioned elevation in relation to muscular or traumatism on musculature delegate physiologically to vomiting. It is never observed any relation with entity of vomiting and elevation of CPK. The causes of elevation represent the 40% of examined subjects.

Beagle dogs were allocated to 4 groups, each consisting of 3 males and 3 females, which received 0.055, 0.165 or 0.495 mg paraquat (PQ)/kg/day sc for 4 w to investigate subacute toxicity. Recovery 4 and 8 w postadministration was studied. In the early stage there was vomiting, decreased activity and undernourishment. Induration and ulcers at the injection sites were seen. The group receiving 0.495 mg PQ/kg had reduced food ingestion and occasional decreases in water consumption until the end of the 4-w injection period. Three animals in the 0.495 mg PQ/kg group were sacrificed in the moribund stage with marked decreases in body weight. Ophthalmologic examination at 4 w of recovery detected hemorrhage around the nasalis vein of the left fundus in 1 animal that received 0.495 mg PQ/kg. No abnormal changes in electrocardiography (ECG) were noted throughout the experimental period. Slightly increased urinary protein, reticulocyte counts, and fibrinogen were observed in a few animals in each group. A few animals that received 0.165 or 0.495 mg PQ/kg had increased phospholipid, blood urea nitrogen, and creatine phosphokinase. The lungs of the moribundly sacrificed animals had moderate atelectasis, localized atelectasis, moderate thickening of alveolar wall and pleura, proliferation of fibroblast-like cells, and abundant fibers in interstitium and alveoli. In the liver there was slight hemorrhage along the gallbladder. On electron microscopy of the lung, proliferation of fibroblasts, myofibroblasts and type II alveolar cells, and some mast cells were observed in thickened alveolar walls. Abundant collagen fibers, destroyed cell debris and mitotic figures of spindle-shaped fibroblasts were also observed in the dilated interstitium.(ABSTRACT TRUNCATED AT 250 WORDS)

Epidemic eosinophilia-myalgia syndrome (EMS) associated with excess L-tryptophan (Trp) consumption in humans has been declared a major public health problem. The EMS problem has not been observed in pigs, nor has comprehensive pathology associated with EMS in humans been described. Experiments were therefore conducted to evaluate the pathology and effects of excess dietary L-Trp for finishing (79 to 119 kg) pigs and to determine an LD50 of Trp for pigs. In Exp. 1, addition of .1 or 1% Trp to corn-soybean meal diets had no effect on growth performance or leukocyte and relative eosinophil counts or on plasma aspartate transferase, creatine phosphokinase, and lactate dehydrogenase activities. Likewise, untoward pathological effects of Trp feeding were not observed in the animals under study. In Exp. 2, supplementing the basal diet with 0, 2, and 4% Trp caused linear (P less than .05) decreases in weight gain, feed intake, and gain:feed ratio. Mortality could not be produced by acute oral dosing in the LD50 study (Exp. 3), wherein Trp doses between 2.00 and 5.71 g/kg of BW were administered by stomach tube. Vomiting occurred at oral doses greater than 5.71 g/kg of BW. These results suggest that oral ingestion of Trp in pigs is safe and that pigs can tolerate considerable excesses of Trp.

A 17-year-old boy who had mitochondrial encephalomyopathy with focal deficiency of cytochrome c oxidase (CCO) activity is described. He experienced 3 episodes of muscle weakness, fatigability, nausea, vomiting and concomitant increase of serum creatine kinase activity, at the age of 13, 15 and 17 years. During interval there was no muscle weakness and the serum creatine kinase activity was within normal range. Increased levels of lactic acid and pyruvic acid were observed in the blood and cerebrospinal fluid. After an aerobic exercise test, lactic acid and pyruvic acid in the blood increased to an abnormally high level, and the arterial blood became acidic (pH 7.297). On EEG, occasional intermittent irregular theta activities were observed in the anterior region, but there were no abnormalities on CT and MRI in the central nervous system. In the biopsied muscle, ragged-red fibers comprised 20% on modified Gomori-trichrome staining and a number of fibers with no CCO activity were scattered throughout. The CCO activity in the mitochondria isolated from the biopsied muscle was reduced to 49.2 nmol/min/mg protein (normal range 144.7-355.8), while other mitochondrial enzyme activities in the electron transport system were normal. From these data, the patient was considered to have a unique form of mitochondrial encephalomyopathy. By the administration of a large amount of coenzyme Q10, episodes of muscle weakness and nausea, and an increase of lactic acid and pyruvic acid in the blood after aerobic exercise test were no longer observed.

Patients may be intolerant of zidovudine for several reasons, the most prominent being hematologic toxicity. In vitro studies demonstrate that zidovudine is toxic to the myeloid and erythroid precursors in the bone marrow; at concentrations of zidovudine near those associated with the optimal antiviral effect in vitro, the proliferative capability of these progenitor cells is reduced 50%-70%. The clinical manifestations of anemia and leukopenia generally are time- and dose-dependent. Strategies for alleviating the hematologic toxicity of zidovudine include the use of hematopoietic growth factors, such as erythropoietin, granulocyte colony-stimulating factor, or granulocyte-macrophage colony-stimulating factor. Myopathy, a recently recognized toxic effect of zidovudine, also appears to be time-dependent. Patients often complain of muscle weakness and discomfort and exhibit an associated elevation in creatine phosphokinase level; dose reduction or discontinuation of therapy generally is required. Some patients have experienced high fever, nausea, and vomiting; however, these effects are unusual and of unclear etiology. The substantial proportion of patients with AIDS or AIDS-related complex receiving zidovudine who experience hematologic or muscular toxicity may benefit from treatment with new antiviral agents, such as dideoxyinosine, with toxicity profiles different from that of zidovudine.

Clinical and immunologic responses of sheep to vaccination and subsequent bluetongue virus (BTV) challenge exposure were studied and compared with those of non-vaccinated sheep. Sheep were vaccinated with inactivated BTV administered with aluminum hydroxide and cimetidine or levamisole. After sheep were vaccinated, precipitating group-specific antibodies to BTV were detected, but serotype-specific neutralizing antibodies were not detected. Cellular immune responses (lymphocyte blastogenesis) to BTV were not detected. After virulent BTV challenge exposure, vaccinated and nonvaccinated sheep developed acute clinical disease of similar severity. Clinical signs included hyperemia and petechiae of oral mucosa and coronary bands of the feet, excess salivation, nasal discharge with crusting, ulceration of the muzzle, and edema of lips and intermandibular space. Marked increases in serum creatine kinase activity were associated with stiff gait, reluctance to move, and vomiting. Fever and leukopenia were detected in most of the challenge-exposed sheep. Viremia and neutralizing antibodies were detected in vaccinated and nonvaccinated sheep after challenge exposure. Bluetongue virus-specific reaginic antibodies were not detected in sera from any of the sheep when the passive cutaneous anaphylaxis test was used.

A 74-year-old woman with refractory congestive heart failure due to long-standing calcific mitral stenosis who refused surgical intervention was treated with percutaneous balloon valvuloplasty. After an uneventful procedure, hemodynamic results were satisfactory with an increase in the mitral valve area from 0.4 to 1.1 cm2. Five hours after the procedure, the patient had a bout of vomiting followed by pulmonary aspiration. Electrocardiography, and in the further course, creatine kinase MB elevation, showed anterior myocardial infarction. Necropsy disclosed embolic material in the mid left anterior descending artery which unequivocally consisted of valvular material. This case demonstrates embolism of valvular debris as a life-threatening, procedure-related complication of percutaneous valvuloplasty of calcific mitral stenosis.

Nausea and vomiting occurring during myocardial ischemia is believed to be associated with inferior wall infarction. However, data supporting such an association are limited, and an alternative hypothesis that cardiac vomiting is related to infarct size has also been advanced. The 2 hypotheses were tested in a cross-sectional study of 265 patients consecutively admitted to the coronary care unit. Nausea or vomiting was a good predictor of myocardial infarction (p less than 0.0001). The odds of having an infarction was 3.14 times greater for patients with nausea or vomiting than for those without these symptoms. Nausea was not a good predictor for inferior wall infarction (p = 0.14): 51% of patients with inferior infarcts had nausea or vomiting and 66% with anterior infarcts had these symptoms. Using peak serum creatine kinase level as an index of infarct size, nausea or vomiting was a good predictor of larger infarction. While 55% of all patients with infarction had nausea or vomiting, for patients with infarctions that produced a peak creatine kinase level of more 1,000 IU/liters, 78% had nausea or vomiting. Sex was a marginally important variable. After adjusting for sex, the presence of nausea or vomiting still predicted infarct size (p less than 0.001). Thus, cardiogenic nausea and vomiting are associated with larger myocardial infarctions but do not suggest infarcts in a particular location.

Tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide, TCAR, Riboxamide, NSC 286193) is a novel C-nucleoside with antitumor activity against several murine tumor models, including Lewis lung carcinoma. The mechanism whereby this compound exerts its antineoplastic effects is most likely related to a state of guanine nucleotide depletion whereby the anabolite, thiazole-4-carboxamide adenine dinucleotide, potently inhibits inosine-5'-monophosphate dehydrogenase. This Phase I study was designed to determine the maximally tolerated dose of Tiazofurin administered on a 5-day, every-28-day schedule. Tiazofurin levels were measured using a high-pressure liquid chromatography assay, and pharmacokinetic studies were performed in patients treated at each dose level. Nineteen patients received a total of 24 courses of the drug in doses ranging from 550 to 2200 mg/sq m. The dose-limiting toxicities were pleuropericarditis and a general illness best described as a "viral-like" syndrome (manifested by severe malaise, headaches, myalgias, fever, nausea, vomiting, and diarrhea). Other toxicity included myelosuppression, hyperuricemia, elevated serum creatine phosphokinase and serum glutamic oxaloacetic transaminase, conjunctivitis, mucositis, and desquamation of the palms of the hands. Plasma clearance of Tiazofurin followed a biexponential pattern with a harmonic mean terminal half-life of 7.6 h. The mean volume of distribution at steady state was 30 liters/sq m, and the mean plasma clearance was 3 liters/h/sq m. The total cumulative urinary excretion ranged from 15 to 49%. The maximally tolerated dose of Tiazofurin on a 5-day schedule was 1650 mg/sq m. The recommended dose for Phase II evaluations is 1100 mg/sq m for 5 days. However, exploration of other schedules which might allow administration of more Tiazofurin combined with biochemical studies including thiazole-4-carboxamide adenine dinucleotide measurements would be desirable.

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.
