Complete displaced lateral condylar fractures of the metacarpus with triangular osteochondral fragments at the palmar articular surface occurred in two Thoroughbred horses. The condylar fractures were repaired with cortical bone screws following removal of the osetochondral fragments via a dorsal arthrotomy and distraction of the condyles. One horse raced successfully after surgery, and the other is being used successfully as an English pleasure mount. 相似文献

Fractures of the distal radius in two horses were repaired by open reduction and interfragmentary compression using screws placed in a lag fashion. One horse had a complete oblique fracture of the medial aspect of the epiphysis of the distal radius and was sound for riding 32 months after surgery. The other horse had an open spiral comminuted fracture with medial displacement of the distal radial fragment. Laminitis developed in the contralateral limb and this horse was euthanatized 5 weeks after surgery. © Copyright 1994 by The American College of Veterinary Surgeons 相似文献

Objective- This clinical report describes surgical correction of diaphragmatic hernia in three young horses.
Study Design- Retrospective investigation of medical records and subsequent racing performance.
Animals- Three young horses with diaphragmatic hernia.
Results- Three young horses with signs of abdominal pain had diaphragmatic hernia causing small intestinal strangulation. The strangulated small intestine was resected and an end-to-end jejuno-jejunal (two horses) or a side-to-side jejuno-cecal anastomosis (one horse) was performed. Diaphragmatic hernias were closed with a continuous suture pattern. All horses recovered and raced. No difference in race records was found between the subject horses and their siblings. One subject horse died of colic at 5 years of age, but the cause of the colic was undetermined. The remaining two horses are in use as broodmares and have produced multiple foals without recurrence of signs of diaphragmatic hernia
Conclusions- Diaphragmatic hernias can be repaired in horses. These horses can achieve race records similar to their siblings and can produce foals without recurrence of signs of diaphragmatic hernia. 相似文献

Abstract— Anagen defluxion is an unusual cause of non-pruritic alopecia in many species. Two cases are described in horses, the onset coinciding with upper respiratory disease associated with pyrexia. Skin biopsies showed typical changes with follicles containing broken hairs of irregular shaft diameter. The alopecia resolved slowly without therapy. Résumé— L'effluvium anagène est une cause rare d'alopécie non prurigineuse dans de nombreuses espèces. Deux cas ont été obserés chez des chevaux. Le début a coincidé avec une atteinte des voies respiratoires supérieures associées à une fièvre. Les biopsies cutanées ont révélé des lésions caractéristiques: follicules contenant des poils cassés de diamètre iérrgulier. L'alopécie s'est progressivement résorbée sans traitement. Zusammenfassung— Anagen-Deflux ist eine ungewöhnliche Ursache für eine nicht pruritische Alopezie bei vielen Spezies. Beim Pferd werden zwei Fälle beschrieben, wobei der Beginn mit einer fieberhaften Erkrankung der oberen Atemwege zusammenfällt. Hautbiopsien zeigten typische Veränderungen mit Follikeln, die abgebrochene Haare mit unregelmäßigem Schaftdurchmesser enthielten. Die Alopezie heilte langsam ohne Therapie ab. Resumen La defluxión de la fase anagenica del pelo es una rara causa de alopecia de tipo no pruriginoso en una variedad de especies. En este artículo se describe el caso de dos caballos, en los cuales el punto más agudo de la enfermedad coincide con afeccion de las vías respiratorias altas acompañada de fiebre. Las biopsias cutáneas demostraron la presencia de cambios típicos en los folículos pilosos que contenían pelos rotos o de diámetro irregular. La alopecia se resolvió de manera lenta sin ningun tipo de terapia. 相似文献

The case histories of 2 horses that required surgery within the orbit are described. In 1 horse, severely comminuted fractures of the left facial area and orbit were repaired in 2 stages, the first consisting of elevation and wiring of the depressed fractures. In the second stage, an autogenous tendon graft from the lateral digital extensor tendon of the left front leg was used to reconstruct the orbital floor and elevate the globe in the orbit. In the second horse, a retrobulbar tumor causing exophthalmos and prolapse of the nictitans was removed by creating a bone flap of the zygomatic process of the frontal bone for exposure. 相似文献

Four horses, 2 to 17 years old, were treated for unilateral avulsion fractures of the tibial tuberosity. Two horses were treated successfully with tension band wiring or plating in combination with lag screw fixation. One horse was euthanatized because of implant failure during recovery and one was euthanatized on day 11 because a longitudinal fracture of the tibial tuberosity occurred through the plane of the screws used for stabilization. 相似文献

Two phenotypically female Warmblood horses were presented at the Clinic for Horses owing to stallion-like behavior. One mare had an enlarged clitoris, whereas the other one showed no signs of ambiguous external genitalia. In both cases, intra-abdominal testicles were removed by laparoscopy. Hormone status, cytogenetic evaluation, and histopathological examination of the gonads were performed. One animal was diagnosed as having XX disorder of sexual development; the other one, as male pseudohermaphrodite. 相似文献

The clinicopathological and immunohistochemical features of two vascular tumors in two young horses are described in the present work. These animals were referred to the Veterinary Teaching Hospital of the University of Córdoba because of the presence of hyperpigmented plaques located in the medial aspect of the left leg and also around the hock (case 1) and in the right front leg (case 2). Some of the lesions showed deep ulceration and severe protrusion with abundant bleeding. The histopathological study revealed that lesions were composed of nonencapsulated, proliferated, closely packed small blood vessels, some of which showed irregular shape, whereas others were similar to capillaries, arterioles, and venules. Neoplastic cells expressed vimentin and factor VIIIar, suggesting their endothelial nature, whereas in the wall of some proliferated vessels, some cells expressed vimentin, α-smooth muscle actin and desmin, an immunophenotype consistent with pericytes, and small muscle cells. These features agree with those reported in human juvenile hemangioma rather than with hemangioma in adult horses. 相似文献

The objective of this retrospective study is to describe a surgical technique to correct large, recurrent, incisional hernias in horses using a polypropylene mesh. The study sample included 15 horses with large hernias (range, 16−43 cm in length) developed after failure of previous abdominal closure. A double-layer polypropylene mesh was inserted between the internal rectus abdominis muscle sheath and peritoneum. Wound healing was assessed using clinical and ultrasonographic examinations. During a follow-up period of 6 months, no major complications related to the surgical procedure were observed. Subfascial retroperitoneal insertion of a double-layer polypropylene mesh is a valuable treatment option in cases of large and complicated incisional hernias in horses. 相似文献

The aim of the present study was to evaluate acellular dermal matrix (ADM) of rat origin for the repair of ventral hernia in horses. The skin from rats, to be used as a graft, was de-epithelialized using hypertonic solution and further decellularized with 0.5% sodium dodecyl sulfate and 0.25% tri-(n-butyl)-phosphate. Under general anesthesia, the hernial ring was exposed and repaired with the ADM graft using inlay graft technique. Blood samples were collected at postimplantation days 0, 15, and 30 and were used for sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis to assess the serum protein concentration of the animals, as well as for gelatin zymography for the identification of matrix metalloproteinases. All animals had an uneventful recovery without clinical signs of wound dehiscence, infection, or recurrence of hernias during 6-month follow-up period. Sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis of concentration of the serum proteins revealed that this was increased at day 15 and had decreased again at day 30. Gelatin zymography showed only one major band of 92 kDa in the serum of all the horses with the implant, but the relative amount of 92 kDa was higher at day 15 as compared with day 0 and day 30. It may be concluded that ADM of rat origin can be used safely in horses for repair of ventral hernia. 相似文献

Resumen— Dos caballos adultos manifestaron un cuadro prurítico y de dolor asociado con una dermatitis generalizada de evolución rápida y consistente en la presencia de pápulas, pústulas y costras. El examen microscópico de extensiones citológicas a partir del exudado purulento reveló la presencia de numerosos queratinocitos acantoliticos, neutrófilos no degenerados y ausencia de microorganismos, lo que sugirió un diagnóstico de pénfigo foliáceo. Las biopsias de piel mostraron dermatofitosis, marcada acantolisis y creció Trichophyton equinum en cultivos fúngicos. Las lesiones en ambos animales se resolvieron tras administrar una terapia tópica con sulfuro de cal. Postulamos que los encimas proteoliticos liberados por las cepas de Trichophyton equinum aisladas fueron los responsables del alto grado de acantolisis detectada citológica e histológicamente.

Marked acantholysis associated with dermatophytosis due to Trichophyton equinum in two horses (Acantolisis marcade en associación con dermatofitosis por Trichophyton equinum en dos caballos).
Abstract— Two adult horses developed a rapidly progressive, generalized, painful, pruritic, papular, pustular, and crusting dermatitis. Microscopic examination of direct smears made from purulent exudate revealed numerous acantholytic keratinocytes, nondegenerate neutrophils, and no microorganisms, suggesting a diagnosis of pemphigus foliaceus. Skin biopsies revealed dermatophytosis with prominent acantholysis, and fungal cultures were positive for Trichophyton equinum. The lesions in both horses resolved in association with topical applications of lime sulfur. It is hypothesized that proteolytic enzymes produced by the strains of T. equinum isolated were responsible for the prominent acantholysis seen cytologically and histologically. 相似文献

Two Quarter Horse mares with hereditary equine regional dermal asthenia (HERDA) were diagnosed with metastatic squamous cell carcinoma (SCC) associated with chronic nonhealing wounds. The lesions were similar to the development of SCC from chronic nonhealing ulcers, known as Marjolin’s ulcers in humans. The horses showed recurrent skin wounds in the saddle and paralumbar regions and were confirmed by molecular techniques as having HERDA. Both horses were maintained as research animals for prolonged periods and received regular veterinary care and wound treatment. Both horses were ultimately euthanized because of their chronic progressive wounds, coupled with declining health. At necropsy, the nonhealing wounds were found to be complicated by infiltrative SCC; both horses had metastasis to lungs. Chronically inflamed, recurrent skin wounds that heal slowly and incompletely as a consequence of HERDA are proposed as a major pathogenetic factor in tumorigenesis. Consistent findings with respect to proliferation index (Ki-67) and mutations of p53 tumor suppressor gene were confirmed by immunohistochemistry in one horse. SCC consistent with Marjolin’s ulcer has been previously suggested in association with chronic ulcers or burn scars in horses, but this is the first report of an association with chronic poor healing wounds in HERDA horses. 相似文献

Objective —To present an alternative surgical technique for the repair of soft palate defects in dogs.
Animal Population —Three Foxhound cross dogs.
Methods —Bilateral buccal mucosal flaps, based at the palatoglossal arches, were raised. One flap was rotated so that the mucosal side created the floor of the nasopharynx. The second flap was rotated so that the mucosal side formed the roof of the oropharynx. The mucosa of the remnant of the soft palate and the pharyngeal walls was incised and the flaps sutured to these free mucosal edges. The caudal ends of the two flaps were sutured to each other.
Results —Complete closure of the soft palate defect was obtained in all three dogs. The dogs were monitored for between 1.5 and 3 years postoperatively, and no long-term problems were encountered.
Conclusions —This surgical technique resulted in an excellent functional separation of the oropharynx and nasopharynx and allowed reconstruction of a large bilateral soft palate defect.
Clinical Relevance —By using the buccal mucosal flaps, as described in this report, a tension-free closure of large soft palate defects can be obtained, thereby eliminating a major cause of failure of this type of reconstructive surgery. 相似文献

An enzyme-linked immunosorbent assay (ELISA) was developed for use in horses to determine serum titers of antibodies of the immunoglobulin classes IgA, IgG, and IgM to Streptococcus equi M-like protein and culture supernatant protein antigens. Serum antibodies were determined in 28 adult horses, including 9 horses with recent S. equi infections, 17 horses without known exposure to S. equi, but without a history of respiratory disease in the preceding 4 months, and 2 horses with clinical purpura hemorrhagica. Serum IgA titers to culture supernatant protein antigen were highest in recently infected horses (P less than 0.001). Serial determinations of antibody titers in the horses with purpura showed that IgG antibodies to both S. equi M-like protein and culture supernatant protein antigens were undetectable initially, but later rose coincidental with clinical recovery from the disease. Possible mechanisms for these findings are discussed. 相似文献

A cranial approach to the humerus was developed for application of a compression plate for repair of comminuted humeral fractures in a weanling foal, a calf, a heifer, and a mature cow. An incision was made from the cranial portion of the greater tubercle of the humerus to the radius. The cranial aspect of the humerus was exposed by retraction of the brachiocephalicus muscle and blunt dissection between the biceps brachii and brachialis muscles. A second plate was applied laterally in the heifer and cow by retraction of the brachialis muscle and elevation of the extensor carpi radialis muscle. Successful fracture reduction, alignment, and stabilization were achieved in all four animals. 相似文献

Objective— To describe the characteristics of unilateral mid‐body proximal sesamoid bone (PSB) fractures, to determine factors associated with the outcome of horses after surgical repair, and to describe a technique for arthroscopically assisted screw fixation in lag fashion. Study Design— Retrospective case series. Animals— Horses (n=25) with unilateral mid‐body PSB fracture. Methods— Medical records (1996–2006), radiographs, and arthroscopic videos of horses with surgically repaired unilateral mid‐body PSB fractures were reviewed. Retrieved data included signalment, affected limb and PSB, fracture characteristics, and surgical technique. Outcome was established by radiographic assessment of healing and race records; categorical data were analyzed using Fisher's Exact test. Results— Medial forelimb PSBs were most commonly affected (80%). Surgical technique and degree of reduction were significantly associated with outcome; 44% of horses with screw repair and none of the horses with wire fixation raced (P=.047). Factors that may have influenced this outcome were differences in fracture reduction (improved reduction in 22% wire repairs and 88% screw repairs, P=.002) and use of external coaptation (22% wire repair and 88% lag screw repair, P=.002). None of the horses with unimproved reduction raced after surgery. Conclusions— Only 28% of horses with mid‐body PSB fractures raced after surgery. Compared with wire fixation, screw fixation in lag fashion resulted in good reduction and is seemingly a superior repair technique. Clinical Relevance— For mid‐body PSB fractures, arthroscopically assisted screw fixation in lag fashion and external coaptation for anesthesia recovery and initial support provides the best likelihood of return to athletic use. 相似文献
