Uterine involution in mares treated with progesterone and estradiol-17 beta. Bacteriology, histology, and scanning electron microscopy were used to evaluate uterine involution in 27 mares treated with daily injections of 150 mg of progesterone and 10 mg of estradiol-17 beta, commencing within 18 hours of parturition. These findings were compared with those for 24 untreated mares at postpartum day 10 or 11. The treatment resulted in significantly (P less than 0.05) greater uterine gland proliferation. Gland density was significantly (P less than 0.05) greater in mares treated for 6 to 10 days than in those treated 2 to 5 days. The proportion of ciliated cells to secreto...
Axial sesamoid injuries associated with lateral condylar fractures in horses. Axial sesamoid injuries were found in 4 of 18 horses with lateral condylar fractures of the metacarpus or metatarsus. The injuries appeared as axial sesamoid fractures or progressive demineralization of the axial border of one of the sesamoids. None of the horses with axial sesamoid injuries returned to performance soundness. Axial sesamoid injury appeared to be an indication of severe fetlock trauma due to condylar fracture. Such injuries appeared to indicate a poor prognosis for return to performance soundness.
Nocardia asteroides infection in horses: a review. From 1965 to 1983, Nocardia asteroides infection was diagnosed in 16 horses at the Veterinary Medical Teaching Hospital, University of California, Davis. In 2 of the cases, the infection was traumatic in origin and local in extent; the horses recovered without relevant antimicrobial therapy. Fourteen horses had pulmonary or disseminated infections that ended fatally. All 14 had various degrees of immunosuppression. Of these, 8 were Arabian foals with combined immunodeficiency disease and 3 were aged horses with hyperadrenocorticism secondary to ACTH-secreting pituitary tumors. Of the other 3, ...
Exsanguination due to gastric ulceration in a foal. An Arabian foal with a congenital heart disease died due to hemorrhage secondary to a large gastric ulcer. Previously, death of foals with gastric ulcers has been due to diffuse peritonitis resulting from gastric ulcer perforation. The foal in this case report died due to hemorrhage secondary to a large gastric ulcer.
Evaluation of febantel used concurrently with piperazine citrate in horses. Fifty horses from a herd known to have benzimidazole-resistant small strongyles were treated with febantel (6 mg/kg), combinations of febantel (6 mg/kg) and piperazine citrate (25 or 55 mg base/kg), thiabendazole (44 mg/kg), or placebo (0.6 ml of water/kg). Pretreatment and 7-day posttreatment fecal examinations were done. Fecal cultures, strongyle egg per gram (epg) counts, sugar flotation fecal examinations, and in vitro testing for benzimidazole resistance were performed. Results of fecal examinations before treatment were similar in all horses, and results of testing were positive for benz...
Surgical management of perineal lacerations and rectovestibular fistulae in the mare: a retrospective study of 47 cases. The case records of 47 mares with third-degree perineal lacerations or rectovestibular fistulae were examined to evaluate their fertility following surgical repair. Of 32 mares bred, 24 became pregnant, suggesting that surgical repair is indicated in any mare with sufficient genetic potential. Perineal trauma after surgical repair was recorded in 3 of 20 mares at subsequent parturition.
Bilateral degenerative coxofemoral joint disease in a foal. Bilateral degenerative coxofemoral joint disease and noninflammatory osteonecrosis in the femoral heads were diagnosed in a 5-month-old Standardbred colt. Cytologic evaluation and bacterial cultures of coxofemoral synovial fluid, and radiographic and pathologic examination of the coxofemoral joints were conducted. The cause was not determined; however, a thrombus found in association with 1 focus of osteonecrosis was suspected as an etiologic factor.
Evaluation of fluorescein dye as an indicator of small intestinal viability in the horse. In 6 horses, 2 types of ischemic lesions were created in small intestinal segments by selective ligation of vessels and intestinal wall for 1, 2, or 3 hours. After confirming the ischemia by IV injection of sodium fluorescein, the ligatures were released. Five minutes later, the fluorescent patterns were documented photographically. Observed patterns ranged from normal (identical to that observed in unaffected bowel) to a patchy distribution of non-fluorescence (indicating incomplete perfusion). None of the experimental segments was normal when reevaluated 1 month later. The typical appearance...
Septic arthritis of the distal interphalangeal joint after neurectomy in a mare. Fracture of the lateral wing of the third phalanx with secondary infection of the distal interphalangeal joint occurred in a neurectomized mare. Puncture of the sole may have been the inciting cause, emphasizing the need for careful daily foot care in neurectomized horses.
Suspected tremetol poisoning in horses. Of 10 horses in a heavily overgrazed pasture, 4 died within 1 week. Clinical signs included muscle tremors, ataxia, reluctance to walk, heavy sweating, and myoglobinuria. Serum creatine kinase, aspartate transaminase, and alkaline phosphatase activities were high. Histopathologic findings were nonspecific. On the basis of clinical signs, clinicopathologic findings, nonspecific histopathologic findings, the condition of the pasture, the identification of numerous white snakeroot plants from which trematone was extracted, and evidence that these plants had been heavily browsed, it was believed t...
Eosinophilic myeloproliferative disorder in a horse. An eosinophilic myeloproliferative disorder resulted in edema and hemorrhagic diathesis in a 10-month-old Standardbred colt. Laboratory abnormalities included severe thrombocytopenia, anemia, mild hypoproteinemia, and marked eosinophilia. Circulating eosinophils were immature or atypical with variation in granule size, disproportionate nuclear to cytoplasmic maturation, and abnormal nuclear size and shape. Bone marrow aspirate had mainly atypical eosinophil precursors, few erythroid precursors, and no megakaryocytes. A blood transfusion and dexamethasone therapy resulted in some improvement; h...
Isolation of Actinobacillus lignieresii from enlarged tongue of a horse. In the horse described herein, Actinobacillus lignieresii was associated with a syndrome identical to wooden tongue in cattle. It responded rapidly to systemic sodium iodide and antibiotic therapy. The definitive diagnosis was based on cytologic examination and culture. If actinobacillosis is suspected, immediate treatment with sodium iodide should be instituted along with supportive therapy.
Equine plasma banking: collection by exsanguination. A procedure was developed for the collection, preparation, storage, and administration of equine plasma. The technique involved exsanguination of anesthetized donor horses via carotid artery catheterization with a large-bore cannula. Blood was collected into plastic bags, allowed to settle by gravity, then transferred into storage bags and frozen. These were quickly thawed when needed.
Medical management of esophageal stricture in seven horses. Esophageal strictures developed in 7 horses that were treated for esophageal obstruction. A soft diet was fed to all horses, with intermittent nasogastric tube feeding in one, and medication included nonsteroidal anti-inflammatory drugs. Maximal reduction in esophageal lumen diameter was evident by 30 days following circumferential esophageal ulceration, after which lumen diameter increased rapidly. Five horses were clinically normal by 60 days after the esophageal injury. Two horses were euthanatized at the owner's request, 16 and 17 days after the original insult.
External lipomas in three horses. Lipomas involving the musculoskeletal system were seen in 3 horses. The lipomas were on the thorax of 2 horses and the stifle of the third horse. The thoracic lipomas were surgically removed. No recurrence has been noted by 8 months in either case. The lipoma on the stifle had invaded the surrounding tissue and the horse was euthanatized. Unlike mesenteric lipomas, which occur in older horses, these lipomas all occurred in horses less than 2 years of age.
Medial condylar fractures of the third metatarsal bone in horses. Fifteen longitudinal fractures involving the medial condyle of the third metatarsal bone were diagnosed in racing Thoroughbreds and Standardbreds. Twelve were repaired surgically with lag screws placed through stab incisions. Two of the horses suffered catastrophic fracture of the third metatarsal bone during recovery from anesthesia, and 3 more sustained complete fractures within 4 days of the repair. Of 3 horses with fractures treated without surgery, 2 healed without complication. Preoperative radiography did not demonstrate a nonlongitudinal fracture component in any of the horses that sus...
Protozoal myeloencephalitis in horses in California. Three cases of equine protozoal myeloencephalitis were diagnosed over a 12-month period in horses that had never left the state of California. These cases suggest that the disease is enzootic in California.
