The physical findings, clinical signs, age, breed and sex distributions, and laboratory data of 117 dogs with untreated Cushing's syndrome were reviewed. Poodles, Dachshunds, and Boxers of all ages were found to be at increased risk, as were dogs of all breeds greater than or equal to 6 years old. Polydipsia, polyuria, progressive bilaterally symmetric alopecia, and abdominal distention were the most frequently observed clinical signs and physical findings. Lymphopenia, eosinopenia, above normal values of serum alkaline phosphatase, serum cholesterol, and sulfobromphthalein dye retention, and below normal urine specific gravity were the most frequent abnormalities found in the laboratory data. About 50% of the dogs had urinary tract infections. Final diagnosis was established on the basis of abnormally high plasma corticosteroid values in response to an intramuscular injection of adrenocorticotropic hormone.

The historical and clinical features and the haematological and biochemical changes in 126 cats with hyperthyroidism are described; 125 of the cats were domestic short- or longhaired, and one was a chinchilla. There were 62 males and 64 females with a mean age of 13.0 years. The duration of signs ranged from two days to two years with a mean of 5.4 months. The historical and clinical features were weight loss, polyphagia, polyuria/polydipsia, tachycardia, hyperactivity, diarrhoea, respiratory abnormalities, other cardiac abnormalities, skin lesions, vomiting, moderately raised temperature, decreased activity, decreased appetite, congestive cardiac failure, haematuria and intermittently decreased appetite. Goitre was palpable in 123 cats. The serum total thyroxine concentrations of the cats were more than three standard deviations above the mean of the reference range. Serum total tri-iodothyronine concentrations ranged from 0.78 to 14.96 nmol/litre and were within the reference range in 11 of the cats. Mild hyperthyroidism was a much commoner cause of high normal or marginally above normal thyroid hormone concentrations than severe, concurrent, non-thyroidal illness. Other common biochemical changes were increased of serum alanine aminotransferase, urea, aspartate aminotransferase, alkaline phosphatase and lactate dehydrogenase. There were minimal changes in the red cell parameters. Leucocyte changes showed two trends: a mature neutrophilia, either with or without an accompanying leucocytosis often in association with a lymphopenia, or an eosinophilia, either with or without a lymphocytosis.

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.

Naturally-occurring hyperadrenocorticism was diagnosed in an 11-year-old female Dachshund with signs of polydipsia, polyuria, pendulous abdomen, weakness, depression and lethargy, and laboratory test abnormalities comprising lymphocytopaenia, eosinopaenia, hypercholesterolaemia and increased plasma alkaline phosphatase concentration. While awaiting hormonal test results, an adrenocorticolytic drug (o,p'-DDD) was administered for 14 days, during which the patient deteriorated. Hormonal assays suggested a functioning adrenocortical tumour, but the poor condition of the patient precluded adrenalectomy. An adrenocortical carcinoma with hepatic metastases was found at necropsy.

Of cases of hyperadrenocorticism in small animals 80-85% are the result of adrenocortical hyperplasia. Middle-aged or older Poodles, Dachshunds, Boston Terriers and Boxers are most commonly affected, and cats rarely. Clinical signs include polydipsia, polyuria, alopecia, abdominal distension, lethargy, weakness, hepatomegaly, calcinosis cutis, testicular atrophy and anestrus. Hematologic and biochemical changes may include neutrophilia, lymphopenia, monocytosis, eosinopenia, increased blood levels of alkaline phosphatase, SGPT, cholesterol, Na and glucose, and decreased K and T4 levels. The high-dosage dexamethasone suppression test helps differentiate pituitary-dependent hyperadrenocorticism from that caused by adrenal tumors. The low-dosage dexamethasone suppression test, determination of plasma ACTH levels, and ACTH response test are additional diagnostic aids in the diagnosis of Cushing's disease. Medical treatment involves oral use of mitotane (o,p'-DDD) at 50 mg/kg/day for 7 days and prednisone or prednisolone at 0.05 mg/kg/day. Hypophysectomy has been used with only 5% mortality in cases of pituitary-dependent hyperadrenocorticism. Adrenalectomy is indicated in cases of adrenal neoplasia.

Hyperthyroidism was diagnosed in 131 cats during a 3 1/2-year period. The cats ranged in age from 6 to 20 years; there was no breed or sex predilection. The most frequent clinical signs included weight loss, polyphagia, increased activity, polydipsia, polyuria, and vomiting. Common serum biochemical abnormalities included high values for alkaline phosphatase activity (75%), lactate dehydrogenase activity (66%), aspartate transaminase activity (66%), and alanine transaminase activity (54%). Electrocardiographic changes included tachycardia (greater than or equal to 240 beats/min) and increased R-wave amplitude in lead II (greater than or equal to 0.9 mV) in 66% and 29% of the 131 cats, respectively. Thoracic radiography in 82 cats revealed cardiomegaly in 40 (49%) of these cats; 16 cats with congestive heart failure also had pulmonary edema or pleural effusion. In 5 cats with markedly increased fecal volume, mean 48-hour fecal fat content was significantly greater than normal, with daily fat excretion 2 to 15 times the upper limit of normal. Base-line serum thyroxine concentrations were increased above normal range in all cats, whereas triiodothyronine concentrations were increased in 127 (97%) of the 131 cats. In 11 cats tested, mean thyroxine concentration did not increase significantly after thyroid-stimulating hormone administration. Mean 24-hour percentage of thyroid radioiodine uptake in 32 hyperthyroid cats was significantly higher (39.1%) than normal (9.2%). Thyroid scans, performed on 126 cats, showed enlargement and increased radionuclide accumulation in 1 thyroid lobe in 36 (29%) and both lobes in 90 (71%) of the cats.

A six-month-old, female German shepherd dog was presented because of depression, anorexia, vomiting, polyuria, and polydipsia of approximately 10 days' duration. The puppy was depressed, and pain could be elicited on palpation of both shoulders and hips. The most significant results of serum chemistries and hematology were hypercalcemia; increased blood urea nitrogen, creatinine, and alkaline phosphatase; and leukocytosis with neutrophilia. Thoracic radiographs revealed a large thymic mass, diagnosed on histological examination as a thymic lymphoma. Radiographs of the shoulders revealed destructive bone lesions involving the proximal metaphyses of the humeri, causing slipped epiphyses. Bone lesions were found at necropsy on the proximal and distal aspects of both humeri and femurs. Bone resorption was due to local neoplastic infiltration and presumed humoral factors secreted locally and systemically by neoplastic thymic lymphocytes.

Persistent hypercalcemia attributable to parathyroid gland hyperplasia was identified in 6 dogs with primary hyperparathyroidism. Clinical signs included polydipsia (n = 4), polyuria (n = 4), and signs caused by cystic calculi (n = 3). Abnormal clinical pathologic findings included hypercalcemia (mean, 13.6 mg/dl; range, 12.6 to 14.7 mg/dl; n = 6), hypophosphatemia (mean, 2.2 mg/dl; range, 1.4 to 2.9 mg/dl; n = 6), high serum alkaline phosphatase activity (mean, 222 IU/L; range, 161 to 286 IU/L; n = 3), and isosthenuria (mean, 1.012; range, 1.006 to 1.017; n = 6). Serum parathyroid hormone concentration was within the reference range or high (mean, 23 pmol/L; range, 7 to 119 pmol/L; reference range, 1.5 to 13 pmol/L) in all dogs. At surgery, the number of large parathyroid glands was variable, being limited to 1 gland in 3 dogs, 2 glands in 2 dogs, and 4 glands in 1 dog. All visibly large parathyroid glands were surgically removed from each dog. Serum calcium concentration decreased into or below the reference range within 72 hours of surgery in all dogs, confirming the diagnosis of primary parathyroid disease. Multiple nodules of adenomatous hyperplasia were identified in each dog. All 6 dogs were treated with vitamin D and calcium carbonate following surgery. The dog from which all 4 parathyroid glands were removed has remained eucalcemic for more than 1 year with vitamin D supplementation. Vitamin D and calcium administration was discontinued within 4 to 12 weeks of surgery in the remaining 5 dogs. These dogs remained eucalcemic without vitamin D supplementation.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this retrospective study was to determine measurements of adrenal glands from longitudinal sonograms, in a large population of dogs and to correlate these measurements to age, sex and descriptors of body size. Dogs were selected from the clinic population presented for routine abdominal ultrasonography between September, 1991 and March, 1994. Dogs with elevated serum cholesterol or alkaline phosphatase levels, polyuria/polydipsia, and/or clinical diagnoses of adrenal pathology were excluded. Dogs with ultrasound-documented abnormalities (mass lesions, abnormal architecture) of either adrenal were not considered. Age, sex, weight and breed were recorded, and the body surface area of each dog was calculated. Adrenal length and caudal polar width were determined from longitudinal, two-dimensional ultrasound images. Adrenal measurements were compared with body size measurements and age using least squares linear regression analysis and the correlation coefficient (r) and coefficient of determination (r2) calculated. One hundred and ninety three dogs were included in the study, with a weight and body surface area range of 1.8-72 kg and 0.2-1.8 m2, respectively. The left adrenal gland (n = 182) length range was from 10.7 to 50.2 mm, and the range of the caudal polar widths was 1.9 to 12.4 mm. Right adrenal gland (n = 85) length range was from 10 to 39.3 mm, and the range of the caudal polar widths was from 3.1 to 12 mm. In dogs where both adrenal gland lengths were measured (n = 74), the right adrenal gland length was less than that of the left in 46 dogs, equal to the left in one dog, and greater than the length of the left in 27 dogs. The strongest linear association was noted between the left adrenal gland length and body weight (kg, r = 0.71, p < 0.0001) or body surface area (m2, r = 0.71, p < 0.0001). Similar significant association was noted between the right adrenal gland length and body weight (kg, r = 0.69, p < 0.0001). A significant positive association was also noted between age and left adrenal gland length, (r = 0.25, p = 0.009). The summation of all four adrenal measurement values (left length and width, right length and width) did slightly improve the correlation (r = 0.74, p < 0.0001) when compared with body weight (kg). There was not a significant difference in the adrenal measurements with regard to sex. With regard to the correlation coefficient values, there was no advantage noted to calculating the body surface area from body weight. The causes for the low degrees of the correlation between adrenal size and the variables investigated in this study are unknown; measurement error, effects of non-adrenal illness on adrenal size, and a non-linear or complex linear relationship between adrenal gland size (as measured by longitudinal parameters) and descriptors of body size are among possible explanations.

As with most liver diseases, the symptoms of hepatitis in dogs are nearly always aspecific: the dogs eat less, are apathetic, sometimes have polyuria/polydipsia, and sometimes have diarrhoea. Hepatoencephalopathy and ascites only occur with these symptoms in very advanced stages of chronic hepatitis. Only a part of the dogs have jaundice. Because of these aspecific symptoms, the diagnosis hepatitis is often not taken into consideration, even though the presence of a liver disease can be easily detected by measuring plasma concentrations of alkaline phosphatase and bile acids, one or both of which are elevated. The diagnosis is confirmed by histological examination of a liver biopsy sample. The most common forms of hepatitis are non-specific reactive hepatitis, acute hepatitis, and chronic hepatitis. Non-specific reactive hepatitis is a reaction against endotoxin as a result of sepsis or an increased gastrointestinal absorption. Treatment is directed to the primary process. Leptospirosis also causes non-specific reactive hepatitis, but then renal insufficiency is the most prominent feature. The diagnosis is made not on the basis of a liver biopsy but on the basis of increased IgM titres against Leptospira. Immediate treatment with antibiotics and infusions at the first signs (jaundice and uraemia) can save the animal's life. Acute hepatitis can develop as a result of infection, toxins, or liver hypoxia. There is no specific treatment, but adequate recovery often occurs with supportive treatment. Corticosteroids are contraindicated. Chronic hepatitis, which can lead to cirrhosis, is the most common form of hepatitis. It is an autoimmune inflammatory reaction that is usually caused by a virus infection but sometimes by poisoning (intoxication). Long treatment with prednisolone or azathioprine is usually successful, but early recognition of the disease increases the likelihood of success. Nowadays, chronic hepatitis due to hepatic copper accumulation in Beddlington terriers can be detected by DNA tests. Such tests make it possible to distinguish between carriers and non-carriers. Affected animals can be kept symptom-free by life-long treatment with zinc gluconate or penicillamine.
