Erythema multiforme major and disseminated intravascular coagulation developed in a dog 24 hours after exposure to a d-limonene-based insecticidal dip. Clinical signs included severe lethargy and weakness, ulceration of the oral mucosa, and erythematous serpiginous, annular, and arciform lesions on the head, trunk, and limbs. Clinicopathologic abnormalities included leukocytosis with neutrophilia, normocytic normochromic anemia, thrombocytopenia, prolongation of prothrombin and partial thromboplastin times, increased fibrin degradation products, hypoproteinemia, hyponatremia, hypochloremia, azotemia, high serum alanine aminotransferase and alkaline phosphatase activities, and high serum bilirubin concentration. Despite intensive supportive care, the dog developed severe intrathoracic and abdominal hemorrhage and died. Necropsy revealed severe diffuse epidermal necrosis and widespread hemorrhage within organs. Insecticidal dips containing d-limonene have the potential to induce various toxic effects, including, possibly, erythema multiforme major, and should be used cautiously.

The pharmacokinetics and toxicity of intravenous lonidamine were investigated in dogs receiving four cycles of lonidamine (400 or 800 mg/m2) +/- whole-body hyperthermia (WBH). Clearance and volume of distribution in dogs receiving lonidamine during WBH increased 1.6-2.3 and 1.9-3.5-fold respectively, relative to dogs receiving lonidamine under euthermic conditions (p < 0.02). In dogs receiving lonidamine under euthermic conditions or 400 mg/m2 + WBH, the area under the lonidamine concentration versus time curve (AUC) measured during the fourth treatment was 21-58% lower than the first treatment AUC. However, in dogs receiving 800 mg/m2 + WBH, the fourth treatment AUC was four-fold higher than the first treatment AUC (p < 0.02). This suggests repeated exposure to 800 mg/m2 lonidamine and WBH impairs lonidamine metabolism. Weakness, hypoglycaemia, and elevations in amylase, alanine aminotransferase, alkaline phosphatase and bilirubin were more severe or occurred exclusively in dogs receiving 800 mg/m2 + WBH. Since these changes were attributable to marked AUC increases, which occurred secondary to repeated exposure to 800 mg/m2 lonidamine during WBH, 400 mg/m2 was identified as the maximum tolerable dose to be administered intravenously to dogs during WBH.

A patient with chronic inflammatory demyelinating polyneuropathy (CIDP) associated with type B and type C hepatitis virus infection is reported. A 54-year-old female who had a blood transfusion at the age of 31 years was diagnosed as a carrier of hepatitis B virus at the age of 43. Liver dysfunction was first noted in 1987 and gradually grew worse year by year. Beginning in early June 1992, the patients general fatigue became worse, her serum GOT and GPT levels became elevated, and she complained of a tingling sensation in her arms and legs. Neurological examination revealed moderate sensory disturbance of the glove-and-stocking type in all of her extremities. Deep tendon reflexes were all diminished. Hepatitis C antibody was detected in the serum at this time. On June 12, 1993, progression of her sensory disturbance was found to be associated with generalized muscle weakness. Cerebrospinal fluid studies showed increased protein without pleocytosis. Motor nerve conduction studies revealed marked prolongation of terminal latencies, reduction of conduction velocities, and abnormal temporal dispersion of the motor potentials. No sensory potentials could be evoked at any of the sites stimulated. Sural nerve biopsy showed segmental demyelination and severe loss of large myelinated fibers as well as some onion bulb formation. A diagnosis of CIDP was made. Treatment with corticosteroids was started, but there was little improvement in neurological function. The liver dysfunction progressed further and ultimately the patient died of hepatic failure. An autopsy demonstrated liver cirrhosis, but no malignant tumors were evident.(ABSTRACT TRUNCATED AT 250 WORDS)

Megaesophagus was diagnosed in 9 adult ferrets. Clinical history of the ferrets included regurgitation, difficulty in swallowing, partial anorexia, and lethargy. Cachexia, dehydration, weakness, and ptyalism were observed on physical examination. Radiography revealed the esophagus of each ferret to be dilated in the thoracic and cervical regions. Of 4 ferrets that had lymphocytopenia, 2 had concurrent leukopenia. Serum biochemical analysis revealed high activity of alanine transaminase (4 ferrets) and aspartate transaminase (3), and hypoglycemia (4). Treatment included administration of fluid, antibiotics, and agents directed against possible primary causes of megaesophagus. Treatments were ineffective, and all of the ferrets died or were euthanatized. All 6 ferrets that were submitted for necropsy had bronchopneumonia, hepatic lipidosis, mild esophagitis, and gastritis. The etiopathogenesis of megaesophagus in the ferrets was not determined.

1. GR95030X, a potent inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, was administered daily to marmosets by gavage. In a Maximum Repeatable Dose (MRD) study, doses of up to 30 mg kg-1 day-1 were administered for 49 days. In a chronic study, animals received dosages equivalent to 0, 1, 2.5, 7.5 and 20 mg kg-1 day-1 for 204 or 205 days. Some animals were maintained without treatment for a recovery period of 29 or 30 days. 2. Clinical signs included poor coat condition, weakness with impaired coordination, lethargy and other behavioural changes. There was also alimentary disturbance, and some deaths occurred at doses of 20 mg kg-1 day-1 and above. 3. Adverse effects upon body weight were seen although some recovery was apparent after the cessation of treatment. 4. Serum cholesterol concentrations were reduced. Very large increases in serum ALT, AST and CK activities were recorded with CK-MM isoenzymes accounting for 80% or more of the total CK enzyme activity. 5. Treatment was associated with muscle fibre atrophy and a sarcolemmal response with little evidence of regeneration. Histological examination revealed vascular changes, glial proliferation and cell death in the brain, with no consistent distribution. Alveolar capillary congestion and alveolar proteinosis indicated that there may have been a reduction in cardiac function. 6. HMG-CoA reductase inhibitors have evident potential to cause myopathy in marmosets. This is believed to be the first report of such an effect.

The physical, clinicopathologic, and survival rates of 77 cats with severe spontaneous hepatic lipidosis are detailed in this report. Cats were subdivided into groups designated as idiopathic lipidosis if no other disease process was recognized, or secondary lipidosis if another disease process was diagnosed. Cats were also subdivided into groups designated as survivors or nonsurvivors on the basis of successful recuperation at 4 months after initial diagnosis. Differences between disease and survival groups were evaluated for significance. Overall, more female cats and middle-aged cats were affected. Presenting complaints of vomiting, anorexia, weakness, and weight loss were common. Physical assessment of most cats showed obvious hepatomegaly, jaundice, dehydration, and a weight loss > or = 25% of usual body weight. Neurobehavioral signs indicative of hepatic encephalopathy, other than ptyalism and depression, were rare. Clinicopathologic features are characterized by hyperbilirubinemia and increased activities of serum ALT, AST, and ALP, with only small if any increase in gamma GT activity. Clinical features distinguishing cats with hepatic lipidosis from those with other serious cholestatic disorders include absence of hyperglobulinemia and low gamma GT activity relative to ALP activity. Although coagulation tests were abnormal in 45% of cats tested (n = 44), few cats showed clinical bleeding tendencies. Most cats received prophylactic vitamin K1 therapy. Forty two cats received aggressive nutritional and supportive care and of these 55% survived. Cats with idiopathic disease were significantly younger, had significantly higher ALP activity and bilirubin concentration, and had a slightly better survival rate than cats with secondary lipidosis. Low PCV, hypokalemia, and an older age were significantly related to nonsurvival. Because of the variety of diets and food supplements used in case management, the influence of nutritional factors on survival could not be evaluated.

Two cases of alcoholic cerebellar degeneration with pyramidal sign were reported. Patient 1 with alcohol dependence syndrome was a 46-year-old woman. After the alcohol abuse of about eight years, she complained of gait disturbance. The gait disturbance progressively worsened in about two months and she could not ambulate freely by herself. Neurological examination revealed nystagmus, ataxic and spastic gait, slight weakness and spasticity of the lower extremities, hyperreflexia of the extremities, bilateral Babinski's signs, and incoordination of the lower extremities. Examination of liver function and serum B12 was normal. Cranial CT scan and MRI revealed atrophy of the cerebellar vermis and dorsal part of the cerebellum. Though neurological signs slightly improved after the admission to our hospital and the abstinence from alcohol abuse, ataxic gait and hyperreflexia of the extremities have continued. Patient 2 was a 58-year-old man. He was a heavy drinker, but was not a patient with alcohol dependence syndrome. After the heavy drinking of about 40 years, he complained of gait disturbance. The gait disturbance had progressively worsened in about four months. Neurological examination revealed ataxic gait, hyperreflexia of the lower extremities, and bilateral Babinski's signs. Laboratory examination revealed slight liver dysfunction with minimal GPT and moderate gamma-GTP elevation. Examination of serum B12 was normal. Cranial CT scan and MRI revealed atrophy of the cerebellar vermis. Though bilateral Babinski's signs disappeared after the abstinence from heavy drinking, ataxic gait and hyperreflexia of the lower extremities have continued. Alcoholic myelopathy without hepatic cirrhosis was rarely reported. In the relation of alcoholic cerebellar degeneration to alcoholic myelopathy, our cases are interesting and important.

Seventy-six cases of acute viral hepatitis in the elderly (65 years old or older) were reviewed. Their clinical symptoms, biochemical pictures and clinical courses were compared with patients less than 40 years old (young) and those 40-64 years old (middle-aged). There were 51 men and 25 women with the mean age of 69 years (range 65 to 78 years). The most common etiology of acute viral hepatitis in the elderly is acute non-A, non-B hepatitis (48.7%), followed by acute hepatitis in HBsAg carrier (44.7%) and acute type B hepatitis (7.9%). Acute hepatitis in HBsAg carrier is the most common etiology in the young and middle-aged patients. Gastric flu, deep or tea colored urine and fatigue-weakness are the common clinical presentations. In conventional liver function tests, serum levels of GPT and albumin tended to be lower in the elderly patients. Overall, 25% of acute viral hepatitis in the elderly were complicated with fulminant hepatic failure or subacute hepatic failure and 18.4% died. The prevalence of fulminant or subacute hepatic failure and the mortality in the elderly were significantly higher than those in the younger patients.

We report a unique case of KAS syndrome presenting as hypersexuality and elevated serum creatine kinase (CK). None of the other members of the patient's family had KAS. The patient had engaged in sexual behavior 4 approximately 5 times a week since his marriage. He did not have gynecomastia or hepatomegaly. Neurological examination revealed facial twitching and tongue atrophy and fasciculations. Mild to moderate muscular atrophy and weakness were evident in the proximal portion of the upper and the distal portion of the lower extremities. Deep tendon reflexes were absent, as were sensory disturbance and sphincter dysfunction. Laboratory data showed mild elevation of transaminase (GOT 113 U/L, GPT 69 U/L) and extreme elevation of CK (4,600 U/L) in serum. Electromyography and muscle biopsy from the left biceps showed chronic neurogenic atrophy. Genetic analysis showed increased expansion of a CAG repeat (44 repeats) in exon 1 of the androgen receptor gene. We diagnosed KAS syndrome based on the genetic analysis. This case is important in illustrating the clinical varieties of KAS syndrome, as well as the importance of genetic analysis in KAS syndrome cases presenting with atypical manifestations and without a family history.

The acute, subchronic and chronic toxicities of 2,4-dichlorophenoxyacetic acid (2,4-D) were studied ir rats. Animals were exposed acutely (600 mg/kg), subchronically (200 ppm for 30 d) and chronically (200 ppm for 180 d) to 2,4-D by the oral route. Clinical, laboratory and histopathological methods were used as indicators of toxicity. After acute exposure, the herbicide decreased locomotor activity and induced ataxia, sedation, muscular weakness (mainly of the hind quarters) and gasping for breath; increased aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (AP), amylase activities and creatinine levels; decreased total protein (TP) and glucose levels; and increased hematocrit values. Subchronic and chronic 2,4-D exposures did not induce overt clinical signs or symptoms of intoxication. However, subchronic herbicide exposure increased AST activity and albumin and hematocrit values, and chronic exposure increased AST, AP and LDH activities, decreased amylase and glucose levels, but did not change hematocrit values. Chromatographic analysis of the serum of chronically exposed rats showed the presence of the herbicide; the amount found (3.76 +/- 1.16 micrograms/ml) suggested the absence of 2,4-D accumulation within the body. Although macroscopic or histopathological lesions were not observed in acutely, subchronically or chronically 2,4-D exposed rats, the laboratory data obtained suggest tissue injuries after dosing, since the results are considered early indicators of primarily hepatic and muscle tissue damage.
