Muscle strain injuries of the hindlimb in eight horses: diagnostic imaging,management and outcomes     

EA Walmsley  CM Steel  JL Richardson  RC Whitton 《Australian veterinary journal》2010,88(8):313-321

Objective To describe the clinical presentation, ultrasound findings, management and outcome in horses with muscle tear injuries of the hindlimbs. Design Retrospective case series Procedure Medical records of eight horses were reviewed and information on signalment, history, presenting complaint, physical examination findings and further diagnostic tests were recorded. Diagnosis of muscle injury was determined by the presence of abnormal ultrasound findings, compared with the contralateral limb, and, when required, nuclear scintigraphy. Follow-up information was obtained via telephone interviews with owners, trainers and referring veterinarians. Results Muscle tears causing lameness were identified in the middle gluteal (3), semitendinosus (1), semimembranosus (2) and gracilis (2) muscles. Tears were classified by ultrasound imaging as partial (6) or complete (2). The degree of lameness did not appear to be indicative of the extent of injury or of completion of healing. Long-term follow-up was available for seven horses and the outcome was favourable in six cases. Conclusions and clinical relevance Ultrasonography is useful in the diagnosis and assessment of moderate to severe muscle strain injuries. The prognosis appears to be favourable in most cases, although recurrence of injury and lameness can delay the return to athletic activity and an inferior outcome with persistent gait abnormality may occur.  相似文献   

Enucleation in birds of prey     

C J Murphy  D E Brooks  T J Kern  K E Quesenberry  R C Riis 《Journal of the American Veterinary Medical Association》1983,183(11):1234-1237

Enucleation in birds requires special consideration. Two case reports are presented as examples of 2 techniques for enucleation in raptors. The first technique utilizes a transaural approach and is suitable only in owls that have extensive external ear openings. The major advantage of this technique is that it allows complete histologic examination of the globe. The second technique is a globe-collapsing procedure that is suitable for any avian species. This technique precludes complete histologic examination.  相似文献

Cardiorespiratory,sedative and antinociceptive effects of dexmedetomidine alone or in combination with methadone,morphine or tramadol in dogs     

Clarisse G Cardoso  Danilo RC Marques  Thiago HM da Silva  Ewaldo de Mattos‐Junior 《Veterinary anaesthesia and analgesia》2014,41(6):636-643

ObjectiveTo evaluate the cardiorespiratory, sedative and antinociceptive effects of dexmedetomidine alone or in combination with methadone, morphine or tramadol in dogs.Study designExperimental, blinded, randomized, crossover study.AnimalsSix mixed breed dogs (two males and four females) weighing 10 ± 4 kg.MethodsThe animals were randomly divided into four treatments: D (10 μg kg^?1 of dexmedetomidine), DM (dexmedetomidine 10 μg kg^?1 and methadone 0.5 mg kg^?1); DMO (dexmedetomidine 10 μg kg^?1 and morphine 0.5 mg kg^?1), and DT (dexmedetomidine 10 μg kg^?1 and tramadol 2 mg kg^?1). The combinations were administered intramuscularly in all treatments. The variables evaluated were heart rate (HR), respiratory rate (f_R), rectal temperature (RT), systolic arterial pressure (SAP), sedation scale and pedal withdrawal reflex. These variables were measured at T0 (immediately before the administration of the protocol) and every 15 minutes thereafter until T105.ResultsA decrease in HR and f_R occurred in all the treatments compared with T0, but no significant difference was observed between the treatments. The RT decreased from T45 onward in all the treatments. The SAP did not show a difference between the treatments, but in the DT treatment, the SAP was lower at T30 and T45 compared with T0. The D treatment had lower scores of sedation at T15 to T75 compared with the other treatments, and the DMO and DM treatments showed higher scores at T60 and T75 compared with DT.Conclusions and clinical relevanceThe treatments with morphine and methadone added to the dexmedetomidine showed higher sedation scores than the control treatment and the treatment with tramadol added to the dexmedetomidine showed no relevant differences in any of the variables evaluated in the study.  相似文献   

Milk production and composition in Danish Holstein,Danish Red,and Danish Jersey cows supplemented with saturated or unsaturated fat

The aim of the experiment was to study the response in milk production and composition of substituting barley with either saturated or unsaturated fat in mixed rations (MR) for dairy cows. The experiment included 35 Danish Holstein (DH), 39 Danish Red (DR), and 31 Danish Jersey (DJ) cows from parturition until week 30 of lactation. Cows were ad libitum fed one of the three MR based on maize and grass/clover silage, barley, soybean meal, and dried sugar beet pulp. In the saturated ration (SFA), C16 rich fat substituted barley on dry matter (DM) basis; in the unsaturated ration (UFA), ground rape and linseed (0.74:0.26 ratio) substituted barley on DM basis; and in the control ration (CO), no barley was substituted. Concentrations of crude fat (CF) of total ration DM was 3.03% in CO, and in diets supplemented to intended similar fat levels 5.65% (SFA) and 5.81% (UFA), respectively. Statistical analyses were performed within breed and random regression was used to test for differences between treatment responses throughout lactations.  相似文献   

Osteochondral fragmentation of the plantar/palmar proximal aspect of the proximal phalanx in racing horses   总被引：1，自引：0，他引：1  

RC WHITTON  NJ KANNEGIETER 《Australian veterinary journal》1994,71(10):318-321

SUMMARY The clinical presentation and outcome of treatment is presented for 26 cases of osteochondral fragmentation of the plantar/palmar proximal aspect of the proximal phalanx. Twenty-three were racing Standardbreds and three were racing Thoroughbreds. The most common reason for presentation was an inability to run straight at high speed. Only eight horses presented for lameness, although on examination 19 were lame. A positive flexion test was recorded in 90% of affected fetlock joints and effusion in 48%. Arthroscopic fragment removal was performed on 23 occasions in 21 horses and arthrotomy in one horse. Of the 16 horses that had returned to racing, 12 had improved their performance, while three showed no improvement, and one was retired for other reasons. In three horses refragmentation occurred after surgery, two of which had improved after initial arthroscopic removal. Degenerative changes within the fetlock joint were detected at surgery in eight horses. Of the four horses treated conservatively, one returned to its previous level of performance temporarily after intra-articular medication, one showed no improvement and two were still resting. Plantar/palmar osteochondral fragmentation of the proximal aspect of the first phalanx is a common cause of low-grade lameness in racing horses, and arthroscopic removal results in improvement in race performance in a high percentage of cases.  相似文献   

Infiltrative corneal lesions resembling fibrous histiocytoma: clinical and pathologic findings in six dogs and one cat.     

J S Smith  S Bistner  R Riis 《Journal of the American Veterinary Medical Association》1976,169(7):722-726

Infiltrating corneal lesions developed in 6 dogs and 1 cat. In each case, the site of origin appeared to be the corneal limbus. The lesions were characterized by continuous growth, a benign appearance, and a tendency to recur following excision keratoplasty. Each lesion was of a proliferative, inflammatory nature, histologically resembling fibrous histiocytoma. Of the 6 dogs in the series, 4 were Collies.  相似文献   

Rearing performance of farmed fallow deer (Dania dama)     

RC MULLEY  AW ENGLISH  AC KIRBY† 《Australian veterinary journal》1990,67(12):454-456

The ability of fallow does to rear fawns to weaning age was examined in a group of 243 adult does of known age (Group 1) and 509 adult does of unknown age (Group 2). All does had between 1 and 8 opportunities to rear fawns. There was an increasing proportion of does that failed to rear a fawn to weaning age as the number of rearing opportunities increased, although most does (93.6%) only failed on one occasion. A small percentage of does in groups 1 and 2 failed repeatedly to rear fawns to weaning. At slaughter, the presumed causes of failure in chronic non-breeders included pyometron, cystic ovaries, cervical cysts, a vulval neoplasm and salpingitis. The overall rearing success of both groups of deer was 82.4% and there was no consistent pattern of rearing failure relating to parity or previous rearing history.  相似文献
