A 10-year-old Tennessee Walking Horse gelding was admitted to the veterinary teaching hospital for evaluation of intermittent fever, lethargy, and anorexia. Initial laboratory analyses revealed anemia and hyperfibrinogenemia. Abdominocentesis and thoracentesis yielded fluid samples with high nucleated cell counts and total protein concentrations. The tentative diagnosis was nonseptic peritonitis. The horse did not improve after 4 days of antimicrobial treatment, and pitting edema of the ventral midline developed. Thoracic radiography and ultrasonography revealed consolidation of the ventral aspect of the lung fields and pleural effusion. Pleuroscopy of the right hemithorax revealed pleural effusion and a soft-tissue mass in the caudal portion of the mediastinum. Findings on biopsy of the liver and mediastinal mass led to a presumptive diagnosis of metastatic cholangiocellular carcinoma. The horse was euthanatized, and the diagnosis was confirmed at necropsy.

The clinical syndrome of a new disease of pigs in four herds in the Humberside area is described. The first signs of the disease were anorexia, lethargy and pyrexia with up to 60 per cent of the dry sows affected. These signs were followed by an increased incidence of abortions which occurred in up to 3.3 per cent of sows, premature farrowings in up to 20.6 per cent of sows and stillbirths and late mummification which affected up to 26.0 and 18.8 per cent of fetuses, respectively. Mortality in neonatal and pre-weaning pigs reached up to 88 per cent and respiratory disease of high morbidity and low mortality occurred in fattening pigs. There were infertility problems in sows, with an increase in returns to service and a failure to show oestrus after weaning or aborting. The signs of the disease in boars were anorexia and malaise. Cyanosis of the extremities affected up to 2 per cent of the animals. The outbreak lasted 11 weeks in all the herds.

Medical records of 11 cats with lymphoma involving large granular lymphocytes were reviewed. All 9 cats tested were FeLV-negative. Ten cats had a history of anorexia, lethargy, vomiting, or diarrhea, and had lymphoma involving abdominal viscera. The most common site of tumor in these cats was the jejunum. One cat had cutaneous masses caused by dermal and epidermal infiltration with neoplastic large granular lymphocytes. The most common hematologic abnormality was leukocytosis, characterized by neutrophilia with a left shift (7 cats); 2 cats had a left shift without neutrophilia. None of the cats had lymphocytosis, but immature large granular lymphocytes were found in the blood of 4 cats. The most common serum biochemical abnormalities were hypoalbuminemia (10 cats), hypocalcemia (10 cats), hypoproteinemia (9 cats), high aspartate transaminase activity (9 cats), and hyperbilirubinemia (8 cats). Large granular lymphocytes were characterized by abundant cytoplasm containing distinct azurophilic granules that varied in size and number. The most common cytochemical staining pattern included detection of alpha-naphthyl butyrate esterase, acid phosphatase, and beta-glucuronidase activities. On examination of histologic sections, granules stained weakly eosinophilic with Giemsa and moderately with periodic acid-Schiff reaction. Ultrastructurally, the granules appeared membrane bound and contained an electron-dense matrix in 4 cats.

Symptomatic viral hepatitis A usually only requires supportive therapy and the majority of cases are managed in the community. The prodromal symptoms of nausea, anorexia and lethargy tend to improve with the onset of clinical jaundice. Fulminant hepatic failure is said to be an uncommon complication, occurring in only 0.14-0.35% of hospitalized cases. However, an increasing incidence has been documented in some northern European countries where up to 20% of cases of fulminant viral hepatitis is due to hepatitis A. This trend parallels the increasingly delayed exposure to hepatitis A and the increased severity of the illness when contracted in later life. The risk of developing fulminant hepatic failure is best monitored using coagulation factor assays, with the prothrombin time and factor V levels being the most favoured. The diagnosis is established with the onset of encephalopathy. Patients progressing to grade 4 encephalopathy have a reasonably good prognosis compared to other aetiologies and survival rates of up to 67% have been obtained with medical management, despite the co-existence of such complications as cerebral oedema, renal and respiratory failure and the metabolic sequelae of acute liver failure. Nevertheless, some patients require emergency liver transplantation and 10 such patients have been reported to date. Transplantation is especially required in older patients (> 40 years) and those who are jaundiced for > 7 days before the onset of encephalopathy. The serum bilirubin and the prothrombin time complement these parameters in the decision making process.

Severe renal oxalosis was diagnosed in 4 male and 1 female purebred Beefmaster calves from herds in southeastern and northwestern United States. Clinical signs included weakness, anorexia, lethargy, alopecia, dehydration, and diarrhea. Results of serum biochemical analysis for 2 calves were consistent with end-stage renal disease. Calves died 2 days to 6 weeks after birth. At necropsy, renal calyces were dilated and contained pale yellow granular calculi. Histologically, there was renal interstitial fibrosis, and cortical and medullary tubules were distended with calcium oxalate crystals. Oxalate crystals were also in the tracheal glands of 1 calf. Severe renal oxalosis in young purebred calves, on widely varied diets, with no known exposure to exogenous oxalates is suggestive of an inherited metabolic defect resulting in primary hyperoxaluria.

Chronic frontal sinusitis in 12 dairy cattle most often was associated with a history of dehorning, in which the sinus was entered (67%), or with respiratory tract disease (25%). The most common organisms isolated were Actinomyces pyogenes and Pasteurella multocida. Signs of infection did not develop for months in some cattle and were often intermittent. The most common clinical signs included anorexia, lethargy, fever, frontal bone distortion, exophthalmos, abnormal posture, nasal discharge, and neurologic abnormalities. Treatment consisted of trephination at 2 sites, drainage and lavage of the sinus cavity, and administration of antibiotics and analgesics. Eight cattle responded well to treatment and were discharged, but 4 others had signs of CNS involvement and died or were euthanatized. Trephination of the frontal sinus cavity at carefully chosen sites and antibiotic treatment are indicated when sinusitis is suspected. Drainage of the sinus cavity is imperative to avoid extension of the infection into the CNS.

Therapeutic use of the anticonvulsant valproate (VPA) has been associated with a rare, but severe and often fatal hepatotoxicity. Cases usually present with lethargy, anorexia, and vomiting with rapid progression to coma. Liver histopathology is characterized by steatosis with and without necrosis. In some instances only necrosis was present. Several hypotheses of pathogenesis have been postulated. These deal mainly with biochemical systems that are known to be affected by VPA, or with the possible idiosyncratic production of toxic VPA metabolites, especially delta 4-VPA. At present, no hypothesis entirely explains the diverse characteristics of the disorder.

Renal amyloidosis was confirmed in 6 related male and female Beagles, ranging in age from 5 to 11 years. The most commonly reported signs of illness included lethargy, anorexia, vomiting, and weight loss. Common clinicopathologic abnormalities were normocytic, normochromic anemia; hypoalbuminemia; azotemia; hypercholesterolemia; proteinuria; and urine specific gravity values below the normal range. Histologic examination of renal tissue from the 6 Beagles revealed moderate to severe glomerular amyloidosis with inconsistently observed mild medullary interstitial amyloidosis. Congo red-stained kidney sections from 4 of 4 affected dogs were potassium permanganate-sensitive, suggestive of reactive amyloidosis. Hereditary predisposition for renal amyloidosis was suspected in these Beagles.

A 10-year-old cat that was kept on a diet consisting largely of raw liver was evaluated because of lethargy, partial anorexia, and weight loss of several months' duration. The cat's head and neck were rigidly extended, and a hard mass was palpable in the ventral cervical region. Cervical and thoracic radiography revealed proliferative bony lesions of the cervical and thoracic vertebrae as well as of the sternum and costal cartilages. Serum vitamin A concentration was 4 times normal. For reasons unrelated to hypervitaminosis A, euthanasia and necropsy were performed 6 months after evaluation. The skull and the cervical and first few thoracic vertebrae were rigidly fused, and the vertebral architecture was altered by deposition of new bone. The sternum and costal cartilages were similarly affected. The historical, physical, radiographic, laboratory, and postmortem findings were consistent with the diagnosis of hypervitaminosis A. On the basis of findings in this cat, hypervitaminosis A should be suspected in any sick cat fed a diet consisting partly or completely of raw liver.

Case records of 32 neonatal calves with the antemortem diagnosis of meningitis were reviewed. Mean age at admission was 6 days (range, 11 hours to 30 days), and the most common concurrent clinical problem was diarrhea (16/32). Twenty-seven of the calves were available for necropsy. At postmortem, there was evidence of septicemia in 22 (81%) of these calves. Escherichia coli was the organism most frequently isolated (11/16; 69%) from the CNS. The major clinical signs of CNS disturbance observed over the course of hospitalization were lethargy, recumbency, anorexia, loss of suckle reflex, and coma. Leukocytosis and a left shift was evident in 11 of 15 (73%) calves. Concurrent metabolic problems that could have aggravated the CNS disturbance included hyperkalemia and respiratory acidosis. Analysis cerebrospinal of fluid from 22 of the calves, revealed pleocytosis, xanthochromia, turbidity, and high total protein concentration. Cytologically, neutrophils predominated in the CSF in calves with acute disease. Mononuclear cells dominated in calves with chronic disease. Microscopically, bacteria were evident in 10 of 22 (45%) of the antemortem CSF samples and bacteria were isolated from slightly more than half (11/19) of the specimens subjected to microbial culturing. Escherichia coli was the agent most frequently isolated from the CSF. Two of the 9 E coli isolates were resistant to trimethoprim potentiated sulfonamide drugs and all (4/4) of the CSF E coli isolates tested for susceptibility to triple-sulfonamide drugs were resistant. Twenty-seven of the 32 calves died or were euthanatized within 2.43 days after hospitalization.(ABSTRACT TRUNCATED AT 250 WORDS)
