During a 28 month period, 82 horses with clinical signs of abdominal pain were examined for left dorsal displacement of the large colon (LDDLC) using percutaneous ultrasound. Left dorsal displacement of the large colon was diagnosed when a gas echo dorsal to the spleen obliterated the dorsal splenic border, or when the colon was observed lateral to the spleen. In 42 horses, ultrasound confirmed a diagnosis of LDDLC and 40 horses had no evidence of LDDLC. There were five false negative results and no false positives. In four horses with LDDLC, the colon was displaced between the spleen and body wall; three of these colic episodes resolved with medical therapy and the fourth required a celiotomy to relieve a sand impaction. The remaining 38 horses had a renosplenic entrapment; surgical correction was elected in 4 horses, 21 horses were corrected by a nonsurgical rolling procedure, 12 were corrected at surgery after an unsuccessful rolling attempt, and one was corrected by rolling but required surgery later because of an additional lesion. Percutaneous abdominal ultrasound was a valuable aid in the diagnosis of LDDLC and in confirming correction of the displacement after a nonsurgical rolling procedure.  相似文献

Efficacy of metoclopramide for treatment of ileus in horses following small intestinal surgery: 70 cases (1989–1992)     

AJ DART  JR PEAUROI  DR HODGSON  JR PASCOE 《Australian veterinary journal》1996,74(4):280-284

Summary: In this retrospective study, postoperative ileus was studied in horses having resection of the small intestine followed by a jejunojejunal (n=35) or a jejunocaecal (n=35) anastomosis. Twenty-six horses received no metoclopramide, 27 received metoclopramide as an intermittent intravenous infusion and 17 horses received metoclopramide as a continuous intravenous infusion (0.04 mg/kg/hour). Horses receiving a continuous infusion of metoclopramide had a reduced total volume (P< 0.001), shorter duration (P< 0.001), and a slower rate (P< 0.001) of postoperative gastric reflux, and a shorter postoperative hospital stay (P< 0.01) when compared to horses receiving no metoclopramide and horses receiving metoclopramide as an intermittent infusion. Horses having jejunocaecostomy performed had a larger volume (P< 0.05), longer duration (P< 0.05), and a greater rate (P< 0.05) of postoperative gastric reflux, and a longer postoperative hospital stay (P< 0.001) than horses undergoing jejunojejunostomy. Horses that had an abdominal drain placed during surgery had a longer length of intestine resected (P< 0.05) and a longer postoperative hospital stay (P< 0.05) than horses without an abdominal drain. Horses that died or were euthanased during the postoperative period had a greater total volume (P< 0.05), longer duration (P< 0.05), and greater rate of postoperative gastric reflux (P< 0.01), a longer length of small intestine resected (P< 0.01), and a shorter postoperative hospital stay (P< 0.05) than horses that survived until discharge from the hospital. In a multivariate regression analysis the continuous infusion of metoclopramide was the only variable that contributed significantly to predicting the total volume (P< 0.001; r²= 0.24), duration (P< 0.001; r²= 0.24) and rate (P< 0.001; r²= 0.25) of postoperative gastric reflux. We concluded that metoclopramide given as a continuous intravenous infusion decreased the incidence and severity of ileus following small intestinal resection and anastomosis in horses.  相似文献   

Follicular Dysplasia of the Portuguese Water Dog     

WILLIAM H. MILLER JR.  DANNY W. SCOTT 《Veterinary dermatology》1995,6(2):67-74

Résumé— Une étude clinique et histologique a été conduite chez 27 chiens d'eau portugais présentant des dépilations cycliques, focales et non inflammatoires. Les observations histologiques ont été comparées aux biopsies réalisées sur 6 adultes normaux et 25 chiots normaux de la même race, sans histoire familiale de dépilations. La chute du poil chez les chiens alopéciques est dûe à une dysplacie folliculaire avec mélanisation anormale des unités pilo-sébacées. Les observations histopathologiques particulières consistent en une apoptose proéminente des kératinocytes des gaines épithéliales internes et externes, et une dissolution de la matrice pilaire des follicules anagènes. L'observation d'une tendance familiale avec apparition précoce suggère un mécanisme héréditaire pour cette dysplasie. [Miller, W.H., Jr., Scott, D.W. Follicular dysplasia of the Portuguese Water Dog (Displasie folliculaire du chien d'eau portugais). Resumen— Se llevó a cabo un estudio en 27 Perros de Agua Portugués con pérdida de pelo ciclica, no-inflamatoria y regionalizada. Los hallazgos histológicos se compararon con biopsias de 6 adultos normales y de 25 carchorros de la misma raza sin antecedentes familiares de pérdida de pelo. La pérdida de pelo en el grupo de animales alopécicos era debida a una displasia folicular con melanización anormal de los complejos pilosebáceos. Como hallazgos histológicos únicos cabe destacar la presencia de un notable número de queratinocitos apoptóticos en la vaina folicular interna y externa asi como la disolución de la matriz del pelo en los foliculos en anagen. Se detectó una tendencia familiar la aparición de esta displasia a temprana edad, lo que sugiere una base herediteria. [Miller, W.H., Jr., Scott, D.W. Follicular dysplasia of the Portuguese Water Dog (Displasia folicular en el Perro de Aguas Portugués). Abstract— A clinical and histologic study was conducted on 27 Portuguese water dogs with non-inflammatory, regionalized, cyclic hair loss. Histologic findings were compared with biopsies from six normal adult and 25 normal puppy Portuguese water dogs with no known relatives with hair loss. The hair loss in the alopecic dogs was due to a follicular dysplasia with abnormal melanization of the pilosebaceous units. Unique histopathologic findings included prominent apoptosis of keratinocytes in the inner and outer root sheath, and dissolution of the hair matrix of anagen hair follicles. A familial tendency with an early age at onset was noted, suggesting an inherited basis for the dysplasia.  相似文献

Seroprevalence of equine herpesvirus 1 in Thoroughbred foals before and after weaning     

JR GILKERSON  DN LOVE  HE DRUMMER  MJ STUDDERT  JM WHALLEY 《Australian veterinary journal》1998,76(10):677-682

Objective To investigate the seroprevalence of equine herpesvirus 1 in foals around weaning and after weaning on two large Thoroughbred farms using a type-specific enzyme-linked immunosorbent assay to determine exposure to infection.
Design A longitudinal population study in groups of Thoroughbred weanling foals.
Study population Two hundred weanling Thoroughbred foals from a population of about 380 foals were enrolled on two adjacent stud farms in the Hunter Valley of New South Wales. Foals on both farms were weaned from February to May 1995 into randomly selected groups of 10 to 15 foals. Farms were selected because of their willingness to cooperate in the survey and because their detailed records of foals and their movements. They were representative of well-managed large Thoroughbred stud farms in New South Wales. Both studs had upper respiratory tract disease among weanling foals around weaning each year although the sero-prevalence of viral respiratory disease on either farm was not known before the study.
Procedure Serum was collected from foals within each group at fortnightly intervals from 9th February until 1st June 1995, and at a single follow-up period in August 1995. Each sample was tested in triplicate using an antibody-detection ELISA which is type-specific for EHV-1 and EHV-4 antibodies.
Results and conclusions There was serological evidence of EHV-1 infection both before and after weaning. The prevalence of EHV-1 antibody in the sample population increased during the study and individual cases of EHV-1 infection were identified. The increase was caused both by the seroconversion of foals within the groups and by the recruitment into the study of foals with pre-existing EHV-1 antibody. Evidence of EHV-1 infection in Thoroughbred foals after weaning has not been reported previously in Australia and this has implications for vaccination regimens.  相似文献   

Detection of EHV-1 and EHV-4 DNA in unweaned Thoroughbred foals from vaccinated mares on a large stud farm     

Foote CE  Love DN  Gilkerson JR  Whalley JM 《Equine veterinary journal》2004,36(4):341-345

REASONS FOR PERFORMING STUDY: A silent cycle of equine herpesvirus 1 infection has been described following epidemiological studies in unvaccinated mares and foals. In 1997, an inactivated whole virus EHV-1 and EHV-4 vaccine was released commercially in Australia and used on many stud farms. However, it was not known what effect vaccination might have on the cycle of infection of EHV-1. OBJECTIVE: To investigate whether EHV-1 and EHV-4 could be detected in young foals from vaccinated mares. METHODS: Nasal and blood samples were tested by PCR and ELISA after collection from 237 unvaccinated, unweaned foals and vaccinated and nonvaccinated mares during the breeding season of 2000. RESULTS: EHV-1 and EHV-4 DNA was detected in nasal swab samples from foals as young as age 11 days. CONCLUSIONS: These results confirm that EHV-1 and EHV-4 circulate in vaccinated populations of mares and their unweaned, unvaccinated foals. POTENTIAL RELEVANCE: The evidence that the cycle of EHV-1 and EHV-4 infection is continuing and that very young foals are becoming infected should assist stud farms in their management of the threat posed by these viruses.  相似文献
