A moose (Alces alces gigas) was inoculated with Brucella suis biovar 4 to better understand the effects of brucellosis in this species. Serum antibody titers increased rapidly and peaked within 21 to 56 days. Fever, leukocytosis, recumbency, anorexia and depression were observed starting 42 days post inoculation. Brucella suis biovar 4 was isolated from blood, lymph nodes, liver and spleen.

1. The authors review the literature describing acute symptomatology produced by the gradual or abrupt withdrawal of heterocyclic antidepressants, monoamine oxidase inhibitors (MAOI) and neuroleptics. 2. Withdrawal of heterocyclic antidepressants and antipsychotic agents causes similar symptomatology. Symptoms produced by the discontinuation of these drugs include nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgias, paresthesias, anxiety, agitation, restlessness, and insomnia. 3. Psychotic relapse is often presaged by anxiety, agitation, restlessness, and insomnia. Prodromal symptoms are distinguished from the effects of neuroleptic withdrawal by a temporal relationship of the latter to reductions in the dosage or discontinuation of antipsychotic agents. 4. Withdrawal of MAOIs can result in severe anxiety, agitation, pressured speech, sleeplessness or drowsiness, hallucinations, delirium, and paranoid psychosis. 5. MAOI withdrawal phenomena resemble the symptoms produced by the discontinuation of chronically administered psychostimulants. 6. The capacity of MAOIs to exert amphetamine-like effects presynaptically and the propensity of somatic treatments for depression to subsensitize presynaptic receptors regulating the release of catecholamines provide a basis for the development of psychotic symptoms upon the withdrawal of MAOI. Evidence for this hypothesis is reviewed.

Poisoning with the plant Lasiospermum bipinnatum was studied in 9 lambs. Intraruminal doses, varying from 1-12 g/kg/day of dried plant, were administered to 8 animals and 1 was fed 2.5 g/kg/day of the material mixed with maize meal for 13 days. Periodic serum analyses were done to monitor liver function. Lambs given 6-12 g/kg/day died or were killed in extremis. Clinical signs included progressive anorexia and depression in all these lambs and icterus in 2 animals. Lambs given 1-4 g/kg/day were sacrificed after about 2 weeks. Clinical signs in these animals were minimal or absent. Hepatosis was found in all the lambs, the severity of which correlated with levels of plant administered. Centrilobular necrosis and haemorrhage occurred in 2 of the 4 lambs given high doses; single cell necrosis of hepatocytes was observed with intermediate doses, and diffuse degeneration, which was more severe peripherally, was seen at various doses. In 1 lamb, degeneration was most severe midzonally. Bile ductule epithelial proliferation was observed in 7 of the 9 poisoned animals. Marked hypertrophy of hepatocellular smooth endoplasmic reticulum was seen in 3 lambs given low doses. The hepatic lesions were compared with those reported for poisoning by other hepatotoxic plants belonging to the family Asteraceae and found to be indistinguishable.

Within the health care of the elderly with prevention, diagnosis, therapy, rehabilitation, nursing care and social service, diagnostic procedures are of great importance to avoid under- and over-diagnosis. Many diagnostic difficulties exist in elderly patients such as changed reference values, changed normal values and changed signs and symptoms. Well-known examples of conditions which are likely to be under-diagnosed include depression and urinary incontinence. Examples are given from the cardiopulmonary field where e.g. dyspnoea showed to be very common, but in only 36% of males and 52% in females related to cardiac failure or pulmonary disease. The most common symptom of acute myocardial infarction in elderly patients was shown to be dyspnoea, whereas chest pain occurred in only one fifth of the cases. In another study of patients with ulcer disease loss of appetite and weight, nausea and anemia were more common than abdominal pain and heartburn. In peritonitis patients, abdominal pain was observed in only just more than half of the cases and guarding and/or abdominal rigidity in about one third. In patients with suspect age dementia a detailed investigation showed the prevalence of organic dementia to be 89% whereas 3% had treatable dementia and 8% non-dementia conditions. In geriatric long-term patients the mean hearing loss in the speech area was about 50 dB, in spite of the fact that only about 10% of the patients had hearing aids. The need for nursing diagnosis is also obvious. It is concluded that a detailed multidisciplinary diagnostic investigation procedure is very important in geriatric medicine.

The effect of thiamin supplementation on the health and general well-being of 80 randomly selected healthy elderly Irish women, from a population with marginal thiamin deficiency, was studied. Key variables affecting thiamin status were controlled. Weekly dietary intakes, subjective feelings, and activity assessments were measured during a 4-week baseline and 6-week double blind treatment period. Clinical assessments were performed during the last week of each period. For treatment, subjects were randomly assigned to either thiamin (10 mg daily) or placebo groups. Compared to baseline and placebo supplemented values, thiamin-supplemented women experienced significantly increased appetite, energy intake, body weight and general well-being, and decreased fatigue. Thiamin supplementation also tended to reduce daytime sleep time, improve sleep patterns, and increase activity. These data suggest that evaluation of thiamin status is indicated when nonspecific conditions such as anorexia, weight loss, fatigue, depression, and sleep disorders are present in elderly persons.

A herd of 15 mature riding horses with a history of anorexia, weight loss, and lethargy was examined. The animals had been fed a 50/50 mixture of commercial sweet feed and corn screenings contaminated with a heavy growth of Fusarium moniliforme. Thirteen of the horses had one or more neurologic signs. The most characteristic signs were profound depression and mild ataxia. Over the 19-day course of the epizootic, the horses had increasing severe neurologic deficits, including unilateral blindness and delirium. Despite the clinical appearance of dehydration, 12 horses had low PCV (16 to 27%), hematocrit (21.2 to 31.0%; determined by automated cell counter), and RBC counts (3.76 to 5.5 x 10(6) RBC/microliters). White blood cell counts were variable (4,900 to 17,000 WBC/microliters). Necropsy findings included diffuse malacia of the white matter of the frontal cortex and severe multifocal perivascular hemorrhage in the white matter of the temporal cortex, basal ganglia, anterior medulla, and pons. One horse had a hepatic lesion consisting of a mixed inflammatory cell infiltrate and bile duct proliferation. The attack rate of this epizootic was 100%. The course of disease was unusually long in some animals. In an experiment, the fusarium-infected corn screenings were fed to horses and did not cause clinical signs or alterations in blood or serum biochemical values.

A four year old Dutch warmblooded mare was born and raised in the province of North-Brabant, the Netherlands. On May 16, 1989, she showed signs of colic, anorexia, depression, ileus, severe dehydration and leukopenia. When the mare collapsed, euthanasia was carried out. Acute colitis and cytoplasmic inclusion bodies in macrophages were observed at autopsy. When an indirect immunofluorescence assay was performed, the Ehrlichia risticii titre of the serum was found to be 1:640.

Severe hypercalcemia is a medical emergency requiring urgent treatment. It most commonly is caused by malignant tumors, as in the case study, but can also be caused by advanced hyperparathyroidism or high serum levels of vitamin D. The patient described in the case study shows clinical evidence of volume contraction due to hypercalcemia-related anorexia and vomiting. His elevated serum concentrations of urea nitrogen and creatinine reflect intravascular volume depletion and hypercalcemia-induced reduction of renal perfusion. He is also likely to have irreversible renal damage as a result of nephrocalcinosis. His central nervous system depression is most likely a result of hypercalcemia, but other central nervous system disorders such as cerebral metastases should be considered. Appropriate treatment would include intravenous fluids to correct volume depletion, dilute extracellular fluid calcium, and promote renal calcium excretion. Before waiting for the effects of volume expansion, the first dose of an inhibitor of bone resorption should be given. The agent of choice now (this may change when second-generation bisphosphonates become available) is plicamycin. Etidronate is a reasonable second choice. Because both drugs require at least 48 hours before their hypocalcemic action is manifest, calcitonin could be used to accelerate the rate of decline of the serum calcium. As the patient becomes more alert, weight-bearing and ambulation should be encouraged. With this combination of therapeutic modalities, this patient's serum calcium level should be corrected within 3 to 5 days. Intermittent injections of mithramycin or etidronate could be given on an outpatient basis approximately once a week in order to maintain the serum calcium within the normal range. One of the most important aspects of treatment in hypercalcemic patients is eradication of the underlying disease, which usually calls for specific antitumor therapy, including chemotherapy, radiation therapy, or surgery. Most of the agents currently available for the correction of hypercalcemia have cumulative toxicities or are only transiently effective and, therefore, their use should be considered a temporizing measure until specific treatment directed at the primary disease takes effect.

A phase I clinical study of intravenous Tegafur was conducted in nineteen previously treated patients with primary lung cancer. The dose of Tegafur was elevated from 1.0 to 3.0 g/m2/day for five consecutive days to determine the maximum tolerated dose. The dose-limiting factors were gastrointestinal and neurological toxicity and fatigability observed with the dose level of 2.5 g/m2/day for 5 days. Hematologic, hepatic and renal toxicities were not observed. Gastrointestinal toxicity including nausea, vomiting, anorexia and diarrhea of over grade 2 were seen to result from the dose of 2.5 g/m2/day. Neurological toxicity consisted of headache, dizziness, anxiety and depression. At the dose level of 2.0 g/m2/day, one patient, who had epileptic seizures in the past, experienced a psychomotor seizure. Depression (Grade 2 CNS toxicity) was observed at the dose level of 3.0 g/m2/day. Dose limiting factors were neurological toxicities. The pharmacokinetics of tegafur and 5-FU (the active form of Tegafur) has been studied in all patients. Serum level of tegafur was measured by HPLC method, and serum level of 5-FU was analyzed by GC-MS method. At the dose level greater than 2.0 g/m2/day for 5 days, the mean serum 5-FU values appear over the therapeutic range (0.1 micrograms/ml). In conclusion, 2.5 g/m2/day for 5 days was considered to be MTD, and 2.0 g/m2/day for 5 days intravenous administration was recommended for the phase II trial of single agent chemotherapy.

Among 307 adults with OCD, early onset (age 5-15 years) was more common in men and later onset (age 26-35 years) in women. Early onset was associated with more checking, and late onset with more washing. More women than men had a history of treated depression; 12% of the women but none of the men had a history of anorexia. More women than men were married. Gender-divergent features may reflect differential aetiological factors. Our sample resembled others in the literature in its slight overall female preponderance, low rate of marriage and low fertility, onset mainly before age 35 years, chronicity, and common present and past depression.
