A 57-year-old female was admitted to our hospital with general lassitude, loss of appetite, nausea, upper abdominal pain, thirst, polydipsia and polyuria. On admission, she had an asymmetrical pear-shaped tumor in the right supraclavicular region and severe hypercalcemia. Plasma C-PTH was elevated to 22.72ng/ml. Plasma calcitonin was also elevated to 336 pg/ml. She died of respiratory and cardiac failure of two weeks after admission without any positive response to the treatment, including hemodialysis. Pathohistologically, the tumor was a parathyroid adenoma. The concentrations of C-PTH, intact PTH and calcitonin in the tumor tissue were markedly high: 4.56 micrograms/g wet, 13.9 ng/g wet and 50.7 ng/g wet, respectively. Immunohistologically, the tumor cells and the fibrous stroma were stained strongly positive to rabbit anti-human calcitonin antibody and rabbit anti-human N-PTH antibody by indirect immunoperoxidase staining. Calcitonin-producing tumors, except for medullary thyroid carcinoma are rarely reported. To our knowledge, this is the first report of such a calcitonin-producing parathyroid adenoma associated with primary hyperparathyroidism.

The medical records of 59 dogs with renal amyloidosis were reviewed. Most dogs with amyloidosis were greater than 6 years old, and females were affected more often than males. Beagles, Collies, and Walker Hounds were at increased risk, whereas German Shepherd Dogs and mixed-breed dogs were at decreased risk. Common historical findings were anorexia, polyuria, polydipsia, lethargy, vomiting, and weight loss. Common laboratory findings were leukocytosis, lymphopenia, nonregenerative anemia, hypercholesterolemia, azotemia, hyperphosphatemia, metabolic acidosis, isosthenuria, cylindruria, and proteinuria. Proteinuria was moderate to severe in most dogs, as assessed by qualitative determination of urine protein concentration, urine protein/urine creatinine ratio, and 24-hour urine protein excretion. Conservative medical management was of little value, and survival ranged from 3 to 20 months in 12 dogs for which this information was available. Moderate to severe diffuse global glomerular amyloidosis was detected in all dogs. Medullary amyloid deposition was multifocal and less severe, but was evident in most dogs. Secondary tubulointerstitial and glomerular lesions were mild or absent in most dogs. Thromboembolism was identified in approximately 14% of affected dogs, underlying inflammatory disease in 37%, and neoplasia in 20%. Laboratory indicators of renal function correlated poorly with histologic lesions, with the exception of glomerular amyloid deposition and "chronic renal disease" index with endogenous creatinine clearance.

Chronic renal failure was diagnosed in 15 Bull terrier dogs. The dogs ranged in age from one to 8 years. History and clinical findings typically included lethargy, anorexia, polyuria, polydipsia and weight loss. Affected dogs were azotaemic, had elevated serum phosphate and cholesterol, and proteinuria was apparent in all dogs tested (13/13). The concentration of urine was consistently in the nil to minimally concentrated range (specific gravities 1.011-1.017). In those dogs necropsied, both kidneys were approximately two-thirds normal size, tough in consistency, with a pale cortex and a finely nodular capsular surface. Histologically, there was marked nephron loss, diffuse interstitial fibrosis and focal dense radial fibrosis which was especially evident in the renal medulla. Tubular dilation was widespread with focal mineralisation of tubular epithelium and adjacent basement membranes. Glomeruli were often shrunken and segmentally fibrotic. Some Bowman's spaces were extremely dilated. Many less severely affected glomeruli had thickened basement membranes.

The effect of i.v. administration of ionophores on metabolism in ruminants was investigated in two experiments. In Exp. 1, four Angus heifers were assigned randomly to receive i.v. monensin (18 mg, n = 2) or vehicle (control, n = 2). Samples were collected from indwelling vena cava cannulas from -60 to 240 min. Concentrations of K, Mg (P less than .05) and P (P less than .10) were lower and glucose (GLU) and free fatty acids (FFA) were higher (P less than .05) in monensin-treated than in control heifers. Serum insulin (INS) initially declined and subsequently increased (P less than .05) following monensin administration. A second experiment was conducted to determine the effect of a higher dose of monensin and the effect of lasalocid on minerals and metabolites. Angus (n = 3) and Hereford (n = 3) steers were randomly assigned to treatments in two 3 x 3 latin square designs. Treatments were i.v. administration of monensin, lasalocid or vehicle (ethanol) administered on three consecutive days. Administration of monensin, but not vehicle or lasalocid, resulted in ataxia, hypernea, polyuria and anorexia for approximately 2 h. Plasma concentrations of K, P and Mg were suppressed (P less than .05) by monensin, but not by vehicle or lasalocid administration. The decrease in K was preceded by a transient increase in K 15 min after administering monensin. Concentrations of GLU and FFA increased (P less than .05) following monensin administration. Concentrations of INS were lower from 60 to 120 min and greater at 180 and 240 min compared with -60 to 0 min from monensin administration (P less than .05). These results provide first evidence of an effect of monensin on metabolism in ruminants independent of alterations in ruminal microbial metabolism.

The medical records of 14 hyperthyroid cats with thyroid carcinoma were analyzed retrospectively regarding historical, physical, laboratory, and thyroid scintiscan findings, treatment, and treatment outcome. Breed predilection was not detected, and older castrated male cats were most commonly affected. The most common clinical signs detected by owners were weight loss, polydipsia, polyuria, polyphagia, hyperactivity, and anorexia. Physical examination findings included tachycardia, palpable cervical mass, hyperactivity, cardiac murmur, and abnormal coat. Common abnormal laboratory findings were high serum thyroxine and triiodo-thyronine concentrations and high serum alanine transaminase, alkaline phosphatase, and aspartate transaminase activities. Azotemia, hyperphosphatemia, and hyperglycemia were noticed less frequently. The most common thyroid scintiscan findings were multiple nodular areas of high radionuclide uptake in the cervical region, thoracic inlet, and cranial mediastinum. The most common morphologic diagnosis was mixed compact and follicular carcinoma, with follicular and papillary carcinomas being less common. Most cats responded well to treatment of the thyroid tumor, with rapid resolution of the historical and physical examination findings. The most common necropsy findings were local tumor invasion, regional lymph node metastases, cardiomyopathy, and interstitial nephritis.

Alkalemia (pH greater than 7.50) was measured in 20 dogs admitted over a 3-year period for various clinical disorders. Alkalemia was detected in only 2.08% of all dogs in which blood pH and blood-gas estimations were made. Thirteen dogs had metabolic alkalosis (HCO3- greater than 24 mEq/L, PCO2 greater than 30 mm of Hg), of which 8 had uncompensated metabolic alkalosis, and of which 5 had partially compensated metabolic alkalosis. Seven dogs had respiratory alkalosis (PCO2 less than 30 mm of Hg, HCO3- less than 24 mEq/L); 4 of these had uncompensated respiratory alkalosis and 3 had partially compensated respiratory alkalosis. Ten dogs had double or triple acid-base abnormalities. Dogs with metabolic alkalosis had a preponderance of clinical signs associated with gastrointestinal disorders (10 dogs). Overzealous administration of sodium bicarbonate or diuretics, in addition to anorexia, polyuria, or hyperbilirubinemia may have contributed to metabolic alkalosis in 8 of the dogs. Most of the dogs in this group had low serum K+ and Cl- values. Two dogs with metabolic alkalosis had PCO2 values greater than 60 mm of Hg, and 1 of these had arterial hypoxemia (PaO2 less than 80 mm of Hg). Treatments included replacement of fluid and electrolytes (Na+, K+, and Cl-), and surgery as indicated (8 dogs). Six dogs with respiratory alkalosis had a variety of airway, pulmonary, or cardiac disorders, and 3 of these had arterial hypoxemia. Two other dogs were excessively ventilated during surgery, and 1 dog had apparent postoperative pain that may have contributed to the respiratory alkalosis.(ABSTRACT TRUNCATED AT 250 WORDS)

A diabetic cat with hyperadrenocorticism had polydipsia, polyuria, ventral abdominal alopecia, thin dry skin, and a pendulous abdomen. Results of laboratory testing indicated persistent resting hypercortisolemia, hyperresponsiveness of the adrenal glands (increased cortisol concentration) to ACTH gel, and no suppression of cortisol concentrations after administration of dexamethasone at 0.01 or 1.0 mg/kg of body weight. Necropsy revealed a pituitary gland tumor, bilateral adrenal hyperplasia, hepatic neoplasia, and demodicosis. Adrenal gland function was concurrently assessed in 2 cats with diabetes mellitus. One cat had resting hypercortisolemia, and both had hyperresponsiveness to ACTH gel (increased cortisol concentration) at one hour. After administration of dexamethasone (0.01 and 1.0 mg/kg), the diabetic cats appeared to have normal suppression of cortisol concentrations. The effects of mitotane were investigated in 4 clinically normal cats. Adrenocortical suppression of cortisol production occurred in 2 of 4 cats after dosages of 25, 37, and 50 mg/kg. Three cats remained clinically normal throughout the study. One cat experienced vomiting, diarrhea, and anorexia.

A 29-year-old nullipara was admitted at 31 weeks' gestation because of toxemia. She noted gradually polyuria, severe thirst, malaise, nausea and anorexia. A water-deprivation test and administration of aqueous vasopressin confirmed the diagnosis of nephrogenic diabetes insipidus. At 33 weeks' gestation, blood chemistry studies revealed moderately elevated transaminase levels and hyperuricemia. Male twins were delivered by vacuum extraction at 35 weeks' gestation. After delivery, she became drousy and icterus appeared. Acute hepatic failure with marked hyperuricemia was diagnosed. She was treated with glucose solution with glucagon and soluble insulin, branched chain amino acids, gabexate mesilate, lactulose and famotidine. Her consciousness cleared rapidly and all laboratory data became normal by 15 days postpartum. The urine volume was about 5 liters per day from the first to sixth postpartum day. The diuresis decreased after the eighth postpartum day. Rare pregnancy complicated by transient nephrogenic diabetes insipidus and acute hepatic failure is discussed.

Chronic active hepatitis with increased hepatic copper concentration was diagnosed in 25 female and 1 male Doberman Pinscher dogs. Common clinical signs included polyuria/polydipsia, weight loss, anorexia, icterus, and ascites. Increased liver enzyme activities and abnormal liver function test results were the most consistent clinicopathologic changes. The dogs were assigned to 3 groups on the basis of clinical course of the disease. Group 1 dogs (n = 12) had clinical signs of advanced liver failure and died within one week. Group 2 dogs (n = 7) had less severe clinical signs of liver disease and died within one month. Group 3 dogs (n = 5) did not have clinical signs of illness or had mild clinical signs of liver disease and died 1 to 42 months after initial evaluation. One dog could not be reevaluated and another dog was alive 3 months after initial examination. Treatments consisted of supportive care for dogs in group 1, and dietary manipulations and corticosteroids for dogs in groups 2 and 3. The association of increased liver copper concentration and chronic active hepatitis is not known.

Infectious bursal disease in 35-day-old specific-pathogen-free (SPF) chickens was characterized clinically by its acute onset and brief duration. Clinical signs included depression, anorexia, diarrhea, and polyuria. A detectable precipitin antibody response occurred between 3 and 5 days postinoculation. Evaluation of pooled serum samples obtained from infectious bursal disease virus (IBDV)-infected chickens revealed transient changes in potassium, cholesterol, uric acid, lactate dehydrogenase, serum glutamic-oxalic transaminase, and serum proteins. Individual serum samples analyzed for uric acid concentration indicated that several IBDV-infected chickens had serum uric acid concentrations above the normal comparison range. Histopathologic examination of lymphoid and nonlymphoid tissues from IBDV-infected SPF chickens affirmed that the predominant lesion was lymphoid necrosis in the bursa of Fabricius. Other lymphoid organs were much less severely affected and possessed greater regenerative potential. Nonspecific and relatively mild changes were found in the liver and kidney: hepatic lipidosis and necrosis, renal intratubular crystalline deposits (probably urates), and increased ectopic lymphoid foci. There was no evidence of immune-complex-mediated arteritis/vasculitis in the sartorius muscle or any other tissue examined. Histopathologic and ultrastructural evidence of glomerulonephritis was rare but compatible with acute immune complexemia.
