An outbreak of chronic liver disease was investigated in a kennel of dogs. Anorexia, depression, polyuria, polydipsia, icterus and a terminal hemorrhagic diathesis were noted in clinically affected dogs. Thrombocytopenia, hypofibrinogenemia, elevated fibrinogen degradation products and prolonged activated partial thrombosplastin times (PTT) and one-stage prothrombin times (PT) were associated with the hemorrhagic crisis. Aflatoxicosis was confirmed by the presence of significant levels of aflatoxicosis was confirmed by the presence of significant levels of aflatoxin B in the commercial dog food being fed. A subacute hepatitis was found on necropsy. Disseminated intravascular coagulation was suspected as the cause of the hemorrhage in these cases and treatment was instituted.

The hypothalamus, in addition to regulating the anterior and posterior pituitary, controls water balance through thirst, regulates food ingestion and body temperature, influences consciousness, sleep, emotion and other behaviors. Much has been learned of these effects in human disease through the clinical manifestations that occur with hypothalamic lesions. This study reviews the clinical pathologic correlations that have been made in recent years showing that regions of the hypothalamus exert functions in humans that are similar to those identified in experimental animals. Clinical pathologic correlations have not always provided precise analysis of hypothalamic function. The hypothalamus is small and often lesions that come to clinical attention achieve considerable size before their recognition, making local anatomic dissections of the effects of the lesions difficult. Nevertheless, the use of modern non-invasive techniques including CT scans and magnetic resonance imaging (MRI) have provided new information not previously available. This paper reviews several cases of hypothalamic disorder recognized recently. (1) A 33-year-old black man with hypothalamic sarcoidosis. Manifestations of hypothalamic dysfunction included panhypopituitarism, aggressive hyperphagia, polydipsia (partially due to hyperglycemia secondary to diabetes mellitus), drowsiness, depression, and irritability. (2) A 37-year-old woman with a large intrahypothalamic tumor (biopsy showed pituitary adenoma), with drowsiness, poikilothermia, lack of satiety, confusion, and memory loss. She becomes depressed when she is transiently more alert (as after hypertonic contrast-dye infusion). (3) A 60-year-old man with hypothalamic compression by a pituitary tumor, associated with syndrome of inappropriate ADH (SIADH), severe anorexia, memory loss, but preserved thirst. After surgical decompression of the tumor his appetite acutely recovered, but he developed severe hypo(poikilo)thermia. (4) A 45-year-old woman with a suprasellar craniopharyngioma presented with severe drowsiness, hyperphagia, depression, and memory loss post-operatively, which responded to antidepressants (except for the memory loss). She had extremely labile blood pressures and serum Na for about 1 week post-operatively.

Epidemiological, clinical, necropsy and histopathological data were accumulated during the study of 15 outbreaks of Senecio spp poisoning in cattle occurring during the last 3 y in the State of Rio Grande do Sul, Brazil. Morbidity averaged 17% and mortality was virtually 100%. The peak mortality occurred during spring and early summer. The most constant clinical signs included anorexia, depression, tenesmus often followed by rectal prolapse, and rough hair coat. Affected animals remained apart from the rest of the herd, lost weight, presented ascites, and had signs of digestive and neurological disturbances. Icterus, photodermatitis, polydipsia, and dependent subcutaneous edema were occasionally noticed. Two main clinical courses could be distinguished. In the protracted form, progressive weight loss terminated with death within many weeks or months. Alternatively, an acute or subacute course led to death in a few days. In both forms, necropsy and histopathological findings included diffuse fibrosis of the liver, hepatomegalocytosis, and biliary hyperplasia. Extrahepatic lesions included gastrointestinal and mesenteric edema, distension, edema and adenomatoid hyperplasia of the gallbladder, and spongy degeneration of the cerebral white matter. S brasiliensis and S oxyphyllus were the species involved in the field outbreaks.

Drinking is an activity determined partly by oropharyngeal stimulation and gastrointestinal sensations as well as biochemical changes, and thirst need not be involved. It is sometimes disturbed in mania or depression. Overdrinking (polydipsia) is common in long-stay in-patients, but only gives rise to water intoxication when there is a variable functional renal abnormality such as SIADH causing water retention. In contrast, in affective disorders, disturbance of sodium retention may be seen, possibly representing failure of nervous vascular control as part of the mental illness.

Li inhibition of noradrenergic adenylate cyclase may be due to inhibition by Li of agonist-induced increases in GTP binding to G-protein. Such inhibition by Li of G-protein function could have effects on phosphatidyl-inositol-mediated second messenger systems as well as on cyclic AMP-mediated systems. However, Sherman, Berridge and others have proposed that Li affects phosphatidylinositol metabolism by inhibiting inositol-1-phosphatase. We recently have been able to measure inositol-1-phosphatase in human red blood cells. Preliminary data on patients treated with Li compared with controls suggests that the enzyme is indeed inhibited in vivo in patients undergoing Li treatment. However, a series of experiments in rats on addition of inositol to Li treatment did not find that inositol could reverse Li effects. Chronic oral high dose inositol does not reverse Li-induced polyuria (measured by polydipsia), Li-induced weight loss or Li-induced depression of exploratory behavior. These results suggest that Li inhibition of inositol-1-phosphatase indeed occurs in vivo. However, the physiological significance of inositol-1-phosphatase inhibition is not yet established.

Ten male and 4 female dogs with chronic hypertrophic pyloric gastropathy were seen at the Sydney Veterinary Teaching Hospital in the period 1982-88. The most commonly affected breeds were the Shihtzu and Maltese. The mean age was 8.2 yr and the mean body weight 6.5 kg. The most common clinical signs were vomiting, weight loss, polydipsia and depression. Hypokalaemia was present in 11 of 12 dogs examined and hypochloraemia in 10 of 11 dogs examined. Five of the six dogs that had blood gases measured were found to have a metabolic alkalosis. Surgery was performed on 13 dogs; pyloromyotomy 7, pyloroplasty 4, gastroduodenostomy 2. There was a recurrence of symptoms in one pyloromyotomy dog, and fatal ulceration and perforation of the cardia occurred in one pyloroplasty case. The remaining 11 dogs had a mean known symptom-free survival time of 20 mo. This study confirms the preponderance of affected males, identifies electrolyte and blood gas disturbances as significant complication of chronic hypertrophic pyloric gastropathy, and suggests that relatively minor surgery (pyloromyotomy) may have a place in the treatment of a selected subgroup of cases.

A patient referred to the authors for evaluation and treatment of depression, behavioral dyscontrol syndrome, and polydipsia is described. The authors reviewed his medical status and, finding damage to his right temporal lobe, conceptualized his symptom constellation as representing interictal syndrome and treated him with carbamazepine. His affective symptoms, but not the polydipsia, improved following treatment with carbamazepine.

The effects of rolipram, a new generation antidepressant which is a selective inhibitor of phosphodiesterase, on the selectively bred Flinders Sensitive Line (FSL) of rats, a genetic animal model of depression, was studied. Acutely, rolipram produced comparable decreases in temperature and activity in the FSL and the Flinders Resistant Line (FRL) rats. Upon chronic treatment there was a trend for rolipram to counteract the shock-induced suppression of activity in the FSL rats, suggesting an antidepressant-like effect. However, both groups gained a significant amount of weight, which appeared to be associated with polydipsia and polyuria. In addition, both groups were significantly more affected by the muscarinic agonist, oxotremorine, than their vehicle-treated counterparts. Thus, the FSL rats, which are genetically supersensitive to cholinergic agonists, are even more sensitive following chronic treatment with rolipram. These unexpected findings suggest that rolipram may not be appropriate as an antidepressant for humans because of undesirable side effects.

Reversal of myocardial biochemical changes with insulin treatment (4 and 8 wk) was studied in 8 and 12 wk streptozotocin (STZ)-diabetic rats. STZ-induced diabetes was characterized by elevations in blood glucose, serum cholesterol, and triglycerides and depressed serum insulin levels. Insulin treatment for 4 and 8 wk completely restored the serum alterations to control values. The polyuria, polydipsia, and polyphagia were also markedly diminished by the insulin treatment. Diabetic rats had pronounced decreases in body, heart, and left ventricular weights, all of which were completely reversed by the insulin treatment. Hydroxyproline accumulation in diabetic rat hearts was only reversed by the 8-wk and not by the 4-wk insulin treatment. STZ produced a significant depletion of left ventricular magnesium content as well as depression of K+-stimulated sarcoplasmic reticulum and myofibrillar ATPase activities. Both the 4- and 8-wk insulin treatment produced a complete recovery of the myocardial magnesium content. No significant changes in sarcolemmal Na+-K+-ATPase and K+-stimulated p-nitrophenyl phosphatase activities were observed in diabetic animals compared with control. The decreased latency of the lysosomal hydrolase, N-acetyl-beta-glucosaminidase, and the increased collagen deposition observed in the diabetic hearts were only partially reversed by the 4-wk insulin treatment, but completely reversed by the 8-wk treatment period.

Ingestion of ethylene glycol was responsible for severe azotemia, acidosis, and abnormal anionic gap value in a pygmy goat. Clinical signs consisted of ataxia, polydipsia, decreased rumen motility, and constipation. Nervous signs included depression, absence of menace response, vertical nystagmus, and terminal convulsions. Four days after onset of clinical signs, antidotal treatment was ineffective. Lesions and oxalate crystals in the kidney were typical of ethylene glycol or plant oxalate toxicosis in other species. Toxicologic analysis revealed ethylene glycol in the rumen content and glycolic acid in urine and ocular fluid.
