Pleural effusion in 37 horses, including 15 acutely affected and 22 chronically affected, was found to be due to a variety of causes, including lymphocarcoma, pulmonary granulomas, coccidioidomycosis, equine infectious anemia, pulmonary abscesses, chronic pneumonia, and primary septic pleural effusion. Age, breed, or sex predilection was not found. Horses with chronic disease had weight loss, increased respiratory rate, dull respiratory sounds in the ventral portion of the thorax, and varying degrees of anorexia. Many horses were anemic. Those acutely affected had respiratory distress or signs of colic and many were anorectic. Most horses with acute primary disease had small volumes of pleural fluid. Culture and cytologic examination of pleural fluid and tracheal washings revealed the causative organism in some instances, but in a number of "primary" cases there were negative results on bacterial culture. The latter cases must be differentiated from other causes of chronic weight loss in the horse.

Eleven cases of sigmoid volvulus in patients aged 76 years in average, without visible signs of necrosis on endoscopy, are reported. All patients were treated within 6 to 48 hours by colic resection and immediate restoration of continuity with a mechanical anastomosis. Morbidity was low, including one case of evisceration and one of pneumonia, and there was no mortality after three months. Early resection seems to prevent the risks of necrosis and recurrence, and to have a good prognosis for survival.

Acute false colonic obstruction occurred in one female and nine male patients aged between 51 and 82 years. They had been admitted to an intensive care unit for respiratory failure (thoracic trauma, pneumonia, chronic or postoperative respiratory failure, or neurological disease). Three patients were in terminal multiple organ failure. There was an associated potassium deficiency in six of the patients. Mechanical ventilatory support was required in eight patients. Plain abdominal X-rays showed caccal diameters greater than 8 cm, confirming the diagnosis. All these patients were initially treated with nasogastric suction, intravenous fluids, potassium replacement, but without success, except in one patient. One spontaneous caecal perforation and a case of impending perforation were treated surgically without prior endoscopy. Nine colonoscopies were carried out with great difficulties. Immediate colic deflation was achieved, but the colic distension resumed 24 h later in six patients. Normal bowel function restarted after colonoscopy in one patient, whilst another one perforated. The air introduced during colonoscopy in the already distended bowel may have speeded up the perforation. Surgery (caecostomy or colostomy) was followed by a return to normal bowel function in seven out of eight patients. One patient died as a result of his spontaneous caecal perforation; the death of three other patients was due to the underlying disease. Ogilvie's syndrome occurring in intensive care patients requires colonic decompression to avoid perforation. Colonoscopy helps to rule out true anatomic occlusion and confirms the diagnosis. However, it is often difficult to carry out, poorly efficient and sometimes dangerous.(ABSTRACT TRUNCATED AT 250 WORDS)

Over a period of approx. 3 years, electrocardiograms (ECG) were recorded from 138 horses referred as patients to the Medical Clinic. Of these, 22 horses (approx. 16 per cent) has ECG alterations. The 22 ECG's revealed a total of 29 ECG abnormalities. The most frequent ECG alteration was incomplete AV block, that was seen in 9 horses (31 per cent of the ECG abnormalities). Abnormal (i.e. broad, tent-like and, sometimes, inverted) T waves and deviations of the ST segment were seen each in 5 ECG's from 7 horses, 3 of which had both abnormalities which were associated with severe underlying disease (colic, enteritis, pneumonia, strangles a.o.). Premature ventricular beats were seen in 3 horses, two of which had serious cardiovascular dysfunction whereas the third showed no signs of cardiac disease. Atrial fibrillation was observed in two horses. Both were treated with chinidine sulphate but a conversion to sinus rhythm was not achieved in either case. Other ECG abnormalities observed in the study were, parasystole (1 horse), sinus arrhythmia (2 horses), sinoatrial block (1 horse) and wandering pacemaker (1 horse). Each abnormality is discussed with regard to its clinical significance and diagnosis. Cardiac murmurs were detected on auscultation of 26 horses (approx. 19 per cent). The murmurs in 15 horses were short and faint sounds most of which were diastolic. They were considered of no importance. Eleven horses, on the other hand, had distinct, loud (grade 4 or 5), holosystolic or holodiastolic murmurs that were considered pathological. Eight of these horses had actual signs of cardiac disease. Cardiac vector distribution in patients with ECG abnormalities or murmurs showed no systematic differences from vectors in horses showing no cardiac abnormality.

Eighteen parasite-free pony foals were infected orally with 500 third stage larvae of Strongylus vulgaris. At 56 days after infection, six ponies were treated with intramuscular ivermectin (22, 23-dihydroavermectin B1); six were treated with oral ivermectin; and six were not treated. Necropsy was done 91 days after infection to study the pathologic effects of migrating S. vulgaris larvae and to determine the efficacy of ivermectin in attenuation of S. vulgaris-induced lesions. Larval migration induced eosinophilic inflammation of the liver, spleen, mesenteric, colic and cecal lymph nodes, and small and large intestine. Previously unreported parasitic lesions included eosinophilic pneumonia with eosinophilic granulomas and pulmonary lymphoid nodules. S. vulgaris larvae were observed in eosinophilic granulomas in the lung, epicardium, liver, and intestinal serosa. Injectable and oral ivermectin formulations were equally effective in reduction of these lesions.

Four month-old foals were infected orally with 75 mL of a suspension of 5.0 x 10(8)Corynebacterium equi per mL. Two foals were killed after ten days and had scanty number of C. equi in the caeco-colic lymph nodes. No C. equi were recovered from the other two foals, killed 20 days after infection. No gross pathological change was detected in these four foals, although mild microscopic lesions were seen in the ileum of one foal. Results of lymphocyte blastogenesis using peripheral blood lymphocytes and C. equi antigens showed, however, that lymphocytes became sensitized to C. equi following this challenge. In a second experiment four month-old foals were given orally the same dose of organisms but on five consecutive days. Two foals were killed ten days after infection and showed mild histological changes in the large bowel mucosa and C. equi could be recovered from all intestinal lymph nodes cultured. In one of these foals moderate numbers of C. equi were present in the bronchial lymph node. Of the other two foals, one died after 22 days with severe ulcerative enterocolitis and intestinal lymphadenitis. Only one small pulmonary abscess was detected despite large numbers of C. equi in the lungs. The other foal developed similar intestinal changes and was euthanized 25 days after infection. No C. equi were detected in the lungs or bronchial lymph node. Lymphocyte blastogenesis in these animals showed a rapid rise in response to C. equi antigens. These studies suggest that C. equi pneumonia in foals does not always arise from an intestinal infection, that minor intestinal infection causes a cellular immune response and that massive exposure of the bowel over a sustained period is necessary to induce intestinal lesions.

An outbreak of equine herpesvirus-1 (EHV-1) occurred on a large stud farm with 133 mares, 54 foals and four stallions, and at least 85 mares, 22 foals and three stallions were infected. Clinical disease was observed in 16 mares, two stallions and 13 foals and the predominant clinical signs were scrotal oedema, ataxia and loss of libido in the stallions, ataxia and recumbency in the mares and uveitis and nasal discharge in the foals, although pneumonia and colic with intussusception were also recorded at autopsy. Neurological disease was more common in the mares nursing foals (12 of 38 infected) than in barren mares (one of 46 infected). Three mares died during the outbreak and no mares that had been recumbent bred again. Control procedures were based on virological and serological testing and stringent management practices to limit the spread of infection between groups of mares and foals and away from the stud farm. There were marked antibody responses in the adult horses, but they were generally poor in the foals; three of the nine viraemic foals did not develop significant increases in the levels of circulating antibody. Recommendations are made for the management of future outbreaks.

The distributions of the incubation periods for infectious and neoplastic diseases originating from point-source exposures, and for genetic diseases, follow a lognormal distribution (Sartwell's model). Conversely, incubation periods in propagated outbreaks and diseases with strong environmental components do not follow a lognormal distribution. In this study Sartwell's model was applied to the age at onset and age at death of foals with Rhodococcus equi pneumonia. The age at onset of clinical signs and age at death were compiled for 107 foals that had been diagnosed with R. equi pneumonia at breeding farms in Argentina and Japan. For each outcome (disease and death), these data followed a lognormal distribution. A group of 115 foals with colic from the University of California were used as a comparison group. The age at onset of clinical signs for these foals did not follow a lognormal distribution. These results were consistent with the hypothesis that foals are infected with R. equi during the 1st several days of life, similar to a point-source exposure.

The present study was planned to investigate the ethnoveterinary methods practiced by the owners of pneumatic-cart pulling camels in Faisalabad Metropolis (Pakistan). During a 7-year-period (November 1992-November 1999), 200 owners of draught camels working in the city were interviewed. Information concerning the ethnoveterinary practices for the treatment of common disorders of digestive tract (indigestion, colic and diarrhea), respiratory tract (cold/rhinitis, pneumonia), skin problems (mange, ulceration of nostrils with or without nasal myiasis, ticks and lice, harness sores), systemic states (fever, ze/rba/d, anhidrosis) and preventive therapy of indigestion and halitosis was collected through interviews and collated with those documented for the treatment of desert-dwelling camels. Familiarity of owners with two traditional methods of surra (trypanosomiasis) diagnosis ('Sand-ball test' and 'Hair-stick test') known to pastorilists was also probed. In addition, the dose and frequency of use of common salt was investigated. Traditional inputs utilized by the camel owners included various plant products, insecticides, sulphur, sump oil, common salt, aspirin, naphthalene balls and milk fat. Different owners used different combinations of traditional drugs for the treatment of disorders/conditions investigated. None of the camel owners was found familiar with the 'Sand-ball test' or 'Hair-stick test' of trypanosomiasis diagnosis. For the prevention of indigestion and halitosis all camel owners had practiced administration of 'massaulas' (physic drench/balls) along with common salt (average 250 g) on weekly basis. Firing had not been used by any owner. In general, the ethnoveterinary treatment practices used by the owners of city-dwelling camels appear to be different from those documented for the treatment of diseases of desert-dwelling camels.
