Groups of six male and six female Beagle dogs were fed diets containing 0, 250, 500, or 1000 ppm fenvalerate for a period of 6 months. Prominent in-life observations related to treatment were emesis, head shaking, biting of the extremities, ataxia, and tremors. One high-dose male dog was sacrificed in extremis during the study period. Mean body weights of 1000-ppm female dogs were significantly lower than those of controls. Red blood cell counts and hematocrit and hemoglobin values in high-dose male and female dogs were significantly lower than those of controls at most sampling intervals. Serum cholesterol and alkaline phosphatase levels were also increased primarily in the high-dose group. Ophthalmic examination revealed changes in retinal vessel tortuosity in some mid- and high-dose dogs. Hepatic multifocal microgranulomata were observed in control and treated dogs microscopically. These changes increased in incidence and severity with dose and were considered to be related to treatment. Histiocytic cell infiltrate in mesenteric lymph nodes in some 500- and 1000-ppm female and 1000-ppm male dogs was the only other treatment-related microscopic effect.

Strychnine toxicosis is characterized by inducible tetanic seizures and metaldehyde poisoning by fine fasciculations progressing to generalized tremors and seizures. Intoxication with 1080 causes seizures, random running movements, vomiting, defecation, urination, acidosis and hyperglycemia. Intoxication with rodenticides causing coagulopathy is characterized by hemorrhage into body cavities but not necessarily external hemorrhage. Anticholinesterase insecticides cause salivation, urination and defecation, while chlorinated hydrocarbon insecticides cause CNS disturbances. Ethylene glycol intoxication results in ataxia, depression, coma, vomiting and tachypnea, followed by acute renal failure. Urea poisoning causes bloat and CNS signs in cattle. Monensin intoxication in horses lasts several days and causes stiffness, colic, uneasiness and recumbency. Salt poisoning results in depression, seizures and hypernatremia. Lead poisoning is associated with central and peripheral nervous system signs, as well as increased numbers of nucleated RBC and basophilic stippling of RBC. Arsenic poisoning results in GI pain, diarrhea, weakness and death. Copper toxicosis in sheep is manifested by hemolytic anemia, hemoglobinemia and hemoglobinuria. Plants that may intoxicate domestic animals include sorghum, greasewood, halogeton, water hemlock, Japanese yew, larkspur, lupine, milk-weed, philodendron, oleander, castor bean and precatory bean.

Snake bite was diagnosed in 125 dogs and 115 cats over 10 years. Young sporting dogs and young cats were mainly affected. More dogs (48%) were seen in contact with tiger snakes than cats (7%). One hundred and four (84%) dogs and 89 (76%) cats were bitten in the warmer months of the year (October to March). As the incidence rose in September/October, dogs were bitten on days when the temperature was near 20 degrees C or over. The commonest presenting signs were dilated pupils and absences of pupillary light reflex. Dyspnoea, hypothermia, hindleg ataxia and glycosuria were common features in cats. Vomiting, tachypnoea, hyperthermia and complete flaccid paralysis were often seen in dogs. The overall recovery rate after administering antivenene was 90% for cats and 83% for dogs. Death from anaphylaxis as a result of giving antivenene occurred in 3 cats and one dog. Dogs treated soon after being bitten recovered more rapidly. There was no correlation between the bite-to-treatment period and the treatment-to-recovery period for cats.

The effects of body temperature and behavior of 2,4-dinitrophenol injected into the cerebral ventricles of the cat was investigated in these experiments. Infused in a volume of 0.1-0.2 ml, 2,4-dinitrophenol produced a dose-dependent fall in body temperature, the duration of which was also dose-dependent. Apart from hypothermia, 2,4-dinitrophenol evoked mydriasis, respiratory irregularities, urination, vomiting, ataxia, muscular weakness, sedation and occasional clonic-tonic convulsions. Of all the autonomic effects, the most consistent was the effect on thermoregulation. The possible mechanisms of action in the brain of 2,4-dinitrophenol on the thermoregulatory mechanisms are discussed.

A 55-year-old man with a subacute onset of slurred speech, ataxia, nystagmus, extrapyramidal rigidity, decreased tendon reflexes, vomiting, bilateral optic atrophy, and clonic jerks died of bronchopneumonia and respiratory failure. Neuropathological examination showed lesions characteristic of subacute necrotizing encephalopathy. Clinicopathological observations of reported cases of Leigh's syndrome in the adult are reviewed.

An acute episode of encephalopathy after the infusion of 16 g methotrexate is reported in a 12-year-old girl with osteogenic sarcoma. The complication occurred during the 11th treatment course, when severe vomiting and diarrhea were followed by a low urine output with consecutive toxic concentrations of methotrexate in serum and cerebrospinal fluid leading to severe systemic and central nervous system toxicity. The onset of the central nervous system toxicity was acute with slurred speech, paresis of the external rectus eye muscles, ataxia, and hemiparesis, and symptoms resolved completely after 30 hours by treatment with calcium leucovorin and forced diuresis. After management of the cerebral and systemic toxicity, high-dose methotrexate treatment could be reinstituted, and was followed by no further complications. In contrast to the transient cerebral dysfunctions, probably caused by embolization of tumor tissue in the early course of high-dose methotrexate treatment, the acute neurologic syndrome observed in the current case after the prolonged use of methotrexate seemed to be related to direct central nervous system toxicity of the drug.

A variant form of maple syrup urine disease (grade II) in a twelve year old boy is reported. The clinical picture was characterized by seizure-like episodes of confusion and intermittent ataxia. The diagnosis was made by showing an increased excretion of branched-chain alpha-hydroxy acids as well as evaluated plasma concentrations of the branched-chain aminoacids and alpha-ketoacids. There was a decrease of leucine degradation in cultured fibroblasts to 5 to 6% of normal. The treatment with thiamine-hydrochlorid remained without any clinical or biochemical effect in our patient. Further neurologic symptoms during acute episodes of vomiting could be avoided by dietary protein restriction and early parenteral glucose supplementation.

We report four cases of carbamazepine toxicity in children associated with the concurrent administration of erythromycin. They all developed clinical toxicity (ataxia, dizziness, nausea, and vomiting) when erythromycin administration was begun; symptoms disappeared after erythromycin was discontinued. Serum carbamazepine levels were measured before, during, and, in most cases, after the toxic episodes. In all cases, there was a sharp increase in carbamazepine concentration after erythromycin therapy was begun and a rapid fall once erythromycin was discontinued. Our data support the previous suggestion that erythromycin interferes with the liver microsomal metabolism of carbamazepine with a subsequent increase in blood levels of the drug.

A 9-year-old boy developed ataxia, right transient hemiparesis, left transient hemichorea, dysarthria and swallowing difficulties with left velar paralysis following two transient episodes of vomiting, headache and dizziness. Angiography demonstrated an occlusion of the distal part of the basilar artery. Thirty-six previously reported cases of vertebro-basilar arterial occlusion in children were reviewed, with particular regard to possible etiologies.

Clinicopathologic findings were retrospectively evaluated in 26 cats and 24 dogs with ethylene glycol intoxication. Common clinical signs were ataxia, depression, vomiting, and hypothermia. Characteristic alterations in the hemogram and serum chemical profile included neutrophilia, lymphopenia, azotemia, hyperphosphatemia, hypocalcemia, hyperglycemia, and decreased whole blood bicarbonate. Common urinalysis findings included isosthenuria, proteinuria, glucosuria, hematuria, calcium oxalate and hippurate crystalluria, and the presence of renal epithelial cells, white blood cells, and granular and cellular casts in the urine sediment. The high death rate (78%) was attributed to delays in presentation, diagnosis, and therapy.
