Application of a Hook Plate for Management of Equine Ulnar Fractures   总被引：1，自引：0，他引：1  

RACHEL C. MURRAY VetMB  MS  Diplomate ACVS    RICHARD M. DEBOWES DVM  MS  Diplomate ACVS    EARL M. GAUGHAN DVM  Diplomate ACVS  LAWRENCE R. BRAMLAGE DVM  MS  Diplomate ACVS 《Veterinary surgery : VS》1996,25(3):207-212

Closed fractures of the proximal aspect of the ulna were repaired in 10 horses younger than or equal to 6 months of age by application of a hook plate using a tension band principle. Ulnar fractures were classified as type 1A (2 horses), type 1B (4 horses), type 2 (1 horse), type 3 (1 horse), and type 4 (2 horses); all fractures had displacement of a proximal fragment. Complications were implant deformation (4 horses), screw pullout (1 horse), osseous sequestration (1 horse), ulnar fracture through a hole used to apply a tension device (1 horse), and metacarpophalangeal deformity associated with a displaced anconeal fragment (1 horse). Hook deformation was likely associated with failure to insert screws in all of the proximal holes of the plate and also in two horses, possibly with difficult recovery from anesthesia. Seven horses were discharged from the hospital and were being used for athletic activities. Insertion of the hook through the tendon of the triceps muscle and incorporation of the fragment within the hook can be used to effectively reduce and stabilize a fragment that might otherwise not hold screws.  相似文献   

Chlorhexidine Gluconate Versus Chloroxylenol for Preoperative Skin Preparation in Dogs     

W. PRESTON STUBBS DVM    JAMIE R. BELLAH DVM  Dipiomate ACVS    DONNA VERMAAS-HEKMAN BS    BARBARA PURICH MS  PAUL S. KUBILIS MS 《Veterinary surgery : VS》1996,25(6):487-494

The efficacy of 3% chloroxylenol (PCMX) or 4% chlorhexidine gluconate (CG) for preoperative skin preparation was assessed in 100 dogs undergoing clean or clean-contaminated surgical procedures. Replication Organism Detection and Counting (RODAC) plates were used to quantify skin bacteria colony forming units (CFU) at the operative site before and after skin preparation and immediately postoperatively. Reduction of CFU after skin preparation and immediately postoperatively was significant for each agent. However, CFU levels were significantly lower in the CG group than in the PCMX group after surgical preparation, regardless of initial CFU numbers. No significant difference in CFU counts was observed between antiseptic groups postoperatively. Within-group comparisons showed PCMX to be significantly less efficacious when the prescrub CFU number was greater than 1,000. Bacterial reduction was similar in the CG group regardless of prescrub CFU levels. The number of negative cultures after skin preparation was significantly greater with CG than with PCMX. Chlorhexidine gluconate also had fewer cultures with heavy bacterial growth (>5 CFUs) after surgical preparation. There was no significant difference between antiseptics in the number of negative cultures or cultures with more than 5 CFUs immediately after surgery. The number of skin reactions and postoperative wound infections that occurred with each technique were similar. Three percent PCMX, as used in this study, was less effective than 4% CG in its immediate antimicrobial activity, however, this difference was not associated with an increased wound infection rate.  相似文献   

Adaptation to a Fat-Supplemented Diet by Cutting Horses     

T.R. Julen MS  G.D. Potter PhD  L.W. Greene PhD  G.G. Stott DVM  PhD 《Journal of Equine Veterinary Science》1995,15(10)

In a crossover experiment, eight mature Quarter Horses were exercised by simulated cutting-horse training and fed either a control concentrate (C) or a 10% fat-supplemented concentrate (F) with Bermuda grass hay in a 60:40 ratio. The experiment consisted of two 28-day experimental periods with a 28-day standardization period between treatments. Digestion trials and standardized exercise tests (SET) were conducted every 7 days during experimental periods. Dietary fat had no detrimental effect on digestion of diet constituents, and all digestion coefficients were within expected ranges. Likewise, there was no significant difference in heart rates between treatments or SET days. Plasma lactic acid concentrations did not differ (P > .05) between treatments, however, there was a decline (P < .05) with advancing SET day. When horses were fed fat, there was an increase (P < .05) in muscle glycogen storage from days 0 to 28, but there was no increase (P > .05) in muscle glycogen over time when horses were fed C. On days 7, 14, and 28, muscle glycogen utilization increased (P < .05) from day 0 when horses were fed fat but not C. Pre-exercise data were normalized such that day 0 values equaled zero, due to higher (P < .05) glycogen concentrations for C than F on day 0. Subsequently, muscle glycogen concentrations on day 28 before exercise were higher (P < .05) when horses were fed F than C. The results of this study indicate that Quarter Horses in simulated cutting-horse training can adapt to digestion of a fat-supplemented diet by day 14. However, it may take up to 28 days of adaptation to a fat-supplemented diet to observe increases in glycogen storage and use.  相似文献   

Xylenol Orange as a Vital Stain to Determine the Viability of Skin Flaps in Dogs     

J. R. BELLAH DVM  D. J. KRAHWINKEL Jr.  DVM  MS  Diplomate ACVS 《Veterinary surgery : VS》1985,14(2):124-126

Intravenous injection of xylenol orange results in generalized violet staining of vascularized skin. The precision of xylenol orange vital staining was compared to fluorescein sodium vital staining and to assessment of skin flap viability by visual observation (color). Skin flaps in the experimental dogs were evaluated by each method at 0, 24, 72, and 120 hours after surgery and subsequently compared to the length of skin flap that remained viable at 216 hours. No significant differences between methods were found at any time interval; however, assessment of skin flap viability was significantly more precise at 24,72, and 120 hours in comparison to the 0 hour assessments. The use of xylenol orange to assess vascular integrity of skin is precise, but no advantage over fluorescein sodium vital staining or assessment by visual observation was noted.  相似文献   

Epidemiologic study of toxoplasmosis on a sheep ranch     

D E Behymer  R Ruppanner  E W Davis  C E Franti  C M Les 《American journal of veterinary research》1985,46(5):1141-1144

An epidemiologic study was done on a ranch in northern California on a flock of ewes that had a history of abortions, mummified fetuses, weak or stillborn lambs, and failure to conceive. Of 56 ewes tested, 33 (59%) had serum agglutinating antibodies against Toxoplasma gondii, with an unusually high proportion of high titers. Over a 2-year-period, reproductive problems were higher (39% to 42%) among the seropositive ewes than among the seronegative ewes (9% to 33%). Of 89 sera received from persons and 7 species of animals on the ranch, 44 (49%) were found to be seropositive to T gondii, including seropositive members of a family of 6. The rancher's wife and teenage daughter, both of whom were involved with lambing, had serum titers exceeding 4,096. Other members of the family not involved with lambing were seronegative by the indirect hemagglutination test. The 2 infected persons are known to have come in contact with placentas, birth fluids, fetuses, and colostrums from these infected ewes.  相似文献   

Strains of Escherichia coli associated with urogenital disease in dogs and cats     

R A Wilson  T J Keefe  M A Davis  M T Browning  K Ondrusek 《American journal of veterinary research》1988,49(6):743-746

Selected strains of Escherichia coli associated with urogenital disease in dogs and cats were evaluated for 3 virulence factors associated with human uropathogenic strains. Urogenital strains of E coli from dogs and cats had high prevalence of alpha hemolysin and were clustered in 5 to 10 somatic serogroups, attributes also shared by human uropathogenic strains. However, the canine and feline urogenital strains failed to have increased prevalence of mannose-resistant hemagglutination, as has been reported for human uropathogenic strains.  相似文献   

Crosspin Fixation of Fractures of the Proximal Tibia in Three Foals     

J. P. WATKINS dvm  MS  J. A. AUER DrMedVet  MS  DiplomateACVS  T. S. TAYLOR dvm  MS 《Veterinary surgery : VS》1985,14(2):153-159

Three foals, each less than 1 month of age, were presented with Salter Type II fractures of the proximal tibial physis. Reduction of the fractures was accomplished manually and maintained by crosspin fixation. Fracture healing in two of the foals was uncomplicated. The third foal developed an infection around the implants, which responded to periodic local antiseptic flushing and administration of penicillin and gentamicin. Follow-up information ranging from 11 to 22 months after surgery revealed satisfactory results in two of three foals; premature closure of the proximal tibial physis was found in the other foal, resulting in the development of an angular limb deformity.  相似文献   

Clinical Feline Toxoplasmosis   总被引：4，自引：0，他引：4  

Michael R. Lappin DVM  PhD    Craig E. Greene DVM  MS    Susan Winston DVM    Sharon L. Toll VMD  Mark E. Epstein DVM 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1989,3(3):139-143

Clinical toxoplasmosis was diagnosed in 15 cats by correlating serologic evidence of infection and clinical signs to either response to therapy or histopathologic demonstration of the organism. Ophthalmic manifestations, primarily involving the anterior segment, were common. Other common physical examination abnormalities included muscle hyperesthesia, fever, and weight loss. Response to therapy was variable, but administration of clindamycin hydrochloride resulted in resolution of all clinical signs not involving the eyes in surviving animals. This drug, alone or in combination with corticosteroids, led to total resolution of clinical signs in four of four cats with active retinochoroiditis and in six of nine cats with anterior uveitis. Four of the 15 cats had concurrent infection with feline immunodeficiency virus (FIV). Feline leukemia virus antigen or antibodies to feline infectious peritonitis virus were not detected.  相似文献
