Atherosclerosis was diagnosed on necropsy in 21 dogs in a 14-year period. Nine dogs died and 12 were euthanatized because of complications associated with the disease. The mean age was 8.5 +/- 0.5 years; 18 dogs were male. Three breeds (Miniature Schnauzer, Doberman Pinscher, and Labrador Retriever) had a higher prevalence of the disease than other breeds in the canine necropsy population of The Animal Medical Center. Most common clinical signs were lethargy, anorexia, weakness, dyspnea, collapse, and vomiting. Hypercholesterolemia, lipidemia, and hypothyroidism were common in affected dogs tested, and protein electrophoresis revealed high values for alpha 2 and beta fractions in all dogs tested. Electrocardiography indicated conduction abnormalities and myocardial infarction in 3 of 7 dogs. Necropsy revealed that affected arteries (including coronary, myocardial, renal, carotid, thyroidal, intestinal, pancreatic, splenic, gastric, prostatic, cerebral, and mesenteric) were yellow-white, thick and nodular, and had narrow lumens. Myocardial fibrosis and infarction also were observed in the myocardium. Histologically, affected arterial walls contained foamy cells or vacuoles, cystic spaces, mineralized material, debris with or without eroded intima, and degenerated muscle cells.

Sarcoidosis is a multisystem disease of unknown etiology characterized by non-caseating granulomatous inflammation of various organs, but most frequently involving the lungs of young adults. Sarcoidosis is rare in the pediatric age group, however numerous extensive reviews have been published. The most commonly seen initial manifestations in childhood are non-specific constitutional symptoms such as lethargy, fatigue and malaise, followed by cough, dyspnea, fever, weight loss, and lymphadenopathy in order of decreasing frequency. The diagnosis is one of exclusion and is established when clinical and radiological findings are supported by histological evidence of widespread non-caseating epithelial cell granulomas in more than one organ, or a positive Kveim test. Laryngeal involvement is usually part of the systemic disease, but isolated laryngeal sarcoidosis has been reported in adults. We report here a case of isolated laryngeal sarcoidosis in a 13 year old girl. The differential diagnosis and management are discussed.

A 64 year old man admitted to hospital with increasing effort dyspnoea and lethargy was found to have a thymoma and pure red cell aplasia. Lymphocytes accounted for 20-30% of marrow cells, and numbers of T8 suppressor/cytotoxic cells in peripheral blood were greatly increased. He remained anaemic after removal of the thymoma despite blood transfusions, and immunosuppression with prednisolone 60 mg and cyclophosphamide 50 mg daily was started. The dose of prednisolone was reduced to 15 mg owing to steroid myopathy and the risk of opportunistic infection. He went into remission, and the dose was further decreased to 10 mg daily.

Groups of 8 male crossbreed domestic goats were given 3 dosage levels of aflatoxin B1 [(AFB1) mg/kg of body weight/day] orally: 0.1 for 34 days; 0.2 for 18 days; or 0.4 for 10 days. Clinical condition, feed consumption, and selected blood values were determined. Clinical signs of toxicosis included decreased feed consumption, slight-to-moderate loss of body weight, mucopurulent nasal discharge, dyspnea, coughing, lethargy, icterus, diarrhea (4 goats), and subnormal body temperature 24 to 48 hours before death. Clinicopathologic changes included increases in total RBC count, PCV, hemoglobin concentration, serum bilirubin concentration, and serum activities of aspartate aminotransferase, isocitric dehydrogenase, and ornithine carbamyl transferase. Goats given the 2 smaller dosage levels of AFB1 had slight increases of serum total protein (TP) concentration compared with control goats, but goats given the larger dosage levels of AFB1 initially had a slight decrease in TP. Aflatoxin had little effect on total WBC count. Serum alanine aminotransferase (ALT) activities in goats given the 2 larger dosage levels of AFB1 were similar to those of control goats, but goats given the smallest dosage level of AFB1 had increased serum ALT activities. Aflatoxin did not produce consistent dose-related changes in serum alkaline phosphatase activities. Seemingly, goats are susceptible to aflatoxin. Onset of clinical signs was dose-related. Onset and magnitude of increases in PCV, hemoglobin concentration, serum bilirubin concentration, and activities of serum aspartate aminotransferase, ornithine carbamyl transferase, and isocitric dehydrogenase were dose-related. Changes in TP and activities of serum ALT and alkaline phosphatase were neither dose-related nor were they potentially useful indicators of toxicosis.

M. pneumoniae is a common cause of pneumonia. The diagnosis is suspected when the patient presents with symptoms suggesting primary atypical pneumonia including cough, fever, chills, headache, and malaise in association with a segmental or subsegmental pulmonary infiltrate(s), the white blood cell count is normal or only slightly elevated, and the Gram stain of the sputum (if any can be obtained) reveals polymorphonuclear leukocytes and few bacteria. The diagnosis is more difficult when the patient presents with symptoms not suggestive of pneumonia including lethargy, dyspnea, and a 1- to 4-week history of shortness of breath without cough or fever in association with diffuse reticulonodular or interstitial pulmonary infiltrates. The disease in the previously healthy host is usually benign and self-limiting. However, the course is shortened by the administration of tetracycline derivatives or erythromycin. M. pneumoniae pneumonia can occur in association with other diseases including sickle cell anemia, sarcoidosis, systemic lupus erythematosus, Hodgkin's disease, and various other immunodeficiency states. In these patients mycoplasma pneumonia can be very serious. Although there is no pathognomonic clinical or radiographic presentation, careful consideration of epidemiologic, clinical, laboratory, and radiographic data are usually sufficient to suggest the diagnosis in most patients.

Fatal Yersinia pseudotuberculosis infection was diagnosed in 3 bushbabies (Galago crassicaudatus) in a large prosimian colony. The clinical signs were diarrhea, dyspnea, hyperthermia, dehydration, and lethargy. Histologically, the disease was characterized by lesions of ulcerative enterocolitis, necrotizing hepatitis, splenitis, lymphadenitis, and nonsuppurative pneumonitis.

Copper deficiency was produced in weanling C57BL/6J and Hap:(ICR) mice that were fed a milk-sucrose based diet supplemented with appropriate vitamins, minerals, and amino acids. Growth retardation, decreased hematocrit, lethargy, dyspnea, achromotrichia, and high mortality (in ICR mice) were apparent in copper-deficient mice. Cardiac enlargement, hemopericardium, hemothorax, and pleural effusion were observed at necropsy. Thrombosis of the atria, myocardial degeneration and necrosis, and sites of myocardial rupture were observed at histopathologic examination.

Bleeding gastric ulcers were a major cause of morbidity and mortality in young swine subjected to surgery, chronic catheterization, and daily experimental manipulation. Some of the animals died suddenly due to exsanguination into the gastrointestinal tract, while others survived for several days following the onset of clinical signs. These signs included dark, tarry stools, lethargy, pale mucous membranes, decreased appetite, and dyspnea. Abnormal clinical laboratory findings included decreased hematocrit, hemoglobin and erythrocyte counts indicative of chronic blood loss anemia. On postmortem examination, single or multiple ulcers of variable sizes were found in the nonglandular cardiac portion of the stomach, and the gastrointestinal tract often contained blood. Histologically, the ulcers had a base of granulation tissue with surface suppuration. Prophylactic treatment of these ulcers was initiated using cimetidine, a histamine II blocker. The drug was administered via the drinking water at 15 mg/kg body weight/day. Fourteen of 62 (22.5%) pigs that did not receive cimetidine developed bleeding ulcers. Of 45 animals given daily prophylactic doses of cimetidine, none manifested clinical signs indicative of a bleeding ulcer. These results indicated that cimetidine was effective in preventing morbidity and mortality due to bleeding gastric ulcers in young swine used in chronic laboratory experiments.

A 5-year-old spayed female Doberman Pinscher was referred for clinical evaluation following two acute episodes of lameness, lethargy, and respiratory dyspnea. The femoral pulse had a bounding "water-hammer" quality. Arterial blood pressures were 280 mm of Hg to greater than 300 mm of Hg during systole and approximately 40 mm of Hg during diastole. Systolic blood pressure was lowered to 210 mm of Hg, using prazosin. Radiography revealed extensive pulmonary interstitial markings and smooth subperiosteal expansions of the long bones indicative of hypertrophic pulmonary osteopathy. Despite symptomatic treatment, the dog's health gradually deteriorated, and it died 9 days after referral. Necropsy revealed vegetative endocarditis of the aortic valve. Insufficiency of the aortic valve was believed to be responsible for the systolic hypertension and the hypertrophic pulmonary osteopathy.

Single-treatment schedules in mice and dogs and multiple-treatment schedules in dogs and monkeys were used to evaluate the toxicity of 2,3-dihydro-1H-imidazo[1,2-b]pyrazole. The LD50 of the iv single dose in male and female mice collectively was 993 mg/kg (2980 mg/m2). The major target organs in mice, dogs, and monkeys were the bone marrow, lymphoid tissue, and gastrointestinal tract. Clinical signs at lethal and high toxic doses were weight loss, diarrhea, hematochezia, emesis, anorexia, mydriasis, dyspnea, lethargy, and stupor. The immediate toxic effect on blood cells was a depression of rbcs with suppression of lymphoid elements occurring later. In dogs, the most toxic schedule was single bolus injections. Attenuation of toxic responses occurred if rest periods were introduced between single or repeated daily dose schedules. The monkeys were more sensitive than the dogs to the high toxic dose on a milligram per meter squared basis, with similar sensitivity to the low toxic dose in the repeated daily injections.
