Objective —To describe the tenoscopic anatomy of the carpal sheath of the flexor tendons (carpal sheath) viewed from a lateral approach.
Study Design —Tenoscopic observation of structures within the carpal sheath subsequently confirmed by dissection.
Animals or Sample Population—12 equine cadaveric forelimbs.
Methods —The limbs were positioned lateral side up with the carpus slightly flexed. After distention of the carpal sheath, a portal for the arthroscope was made approximately 3 cm proximal to the distal radial physis and 2.5 cm caudal to the radius between the tendons of the ulnaris lateralis and lateral digital extensor muscles.
Results —A lateral tenoscopic approach was adequate to identify all structures within the carpal sheath. From proximal to distal, structures identified using this approach were the radial head of the deep digital flexor muscle, accessory ligament of the tendon of the superficial digital flexor muscle, distal radial physis, tendons of the superficial and deep digital flexor muscles, accessory carpal bone, antebrachiocarpal and middle carpal joints, and vincula of the tendon of the deep digital flexor muscle.
Conclusions —A lateral tenoscopic approach offered an easy, repeatable entry into the carpal sheath and allowed good observation of all structures within the sheath except for the medial borders of the tendons of the deep and superficial digital flexor muscles.
Clinical Relevance —Applications of a lateral tenoscopic approach to the carpal sheath include diagnostic procedures, lavage and synovial resection for septic tenosynovitis, desmotomy of the accessory ligament of the tendon of the superficial digital flexor muscle for flexural deformity or tendinitis, and removal of osteochondromas from the distal radial metaphysis. 相似文献

Magnetic resonance (MR) imaging is important in diagnosing musculoskeletal injuries in horses. However, there is still much to learn regarding the significance of lesions identified in equine MR images. Of particular importance is the clinical significance of signal change as a function of pulse sequence. We hypothesized that a resolution of tendon, ligament, and bone marrow lesions on short‐tau inversion recovery (STIR) images would be associated with a return to soundness, and that a persistence of tendon and ligament lesions on only T1‐weighted (T1w) gradient recalled echo (GRE) images would not be associated with persistent lameness. The medical records and MR images of 27 horses that had a hyperintense lesion in initial STIR MR images followed by a subsequent follow‐up MR imaging examination were reviewed. Horses whose tendon or ligament lesions had resolved on STIR images at the time of the recheck examination were significantly more likely to be sound than horses whose lesions persisted on STIR images (P=0.039). This association did not exist in horses with bone marrow lesions (P=1.00). Horses whose tendon or ligament lesions persisted only on T1w GRE images were no more likely to be sound than horses whose lesion persisted on at least one other sequence type (P=0.26). However, the low number of horses included in this analysis may have precluded identification of a significant difference in lameness status. Tendon or ligament lesions visualized on STIR images may represent active lesions that may contribute to lameness in the horse. 相似文献

Seventy-two hours after the administration of a single dose of high passage living attenuated feline panleucopaenia vaccine, cats were protected against experimental challenge and even at 48 hours the effects of challenge were reduced. The antibody response persisted at high titre for at least 23 months. Antibody titres following vaccination were better than those associated with virulent virus. The attenuation of virulent feline panleucopaenia virus by serial passage in feline embryonic cell culture has produced a living vaccine which is both antigenic and immunogenic. Résumé. Soixante-douze heures après l'administration d'une seule dose du vaccin pour maladie des jeunes chats, vaccin vivant atténué à passage élévé, les chats étaient protégés contre des tests expérimentaux et les effets des tests étaient même réduits à 48 heures. La réponse anticorps a persisté à titre élévé pendant au moins 23 mois. Des titres anticorps suivant la vaccination étaient meilleurs que ceux associés avec le virus virulent. L'atténuation du virus virulent pour la maladie des jeunes chats, par passage en série dans la culture des cellules embryonnaires chez les félins, a produit un vaccin vivant qui est à la fois antisomatogtne et immunogène. Zusammenfassung. Zweiundsiebzig Stunden nach der Darreichung von hoher Passage leben-derattenuierter Katzenfieber- (Agranulozytose) Vakzine waren Katzen gegen experimentale Immunitätsteste geschützt und selbst nach 48 Stunden waren die Auswirkungen des Immunitätsteste reduziert. Die Schutzstoffreaktion hielt bei hohem Titer für wenigstens 23 Monate an. Schutzstofftiter die einer Impfung folgten waren besser als jene die mit virulentem Virus verbunden sind. Die Verminderung von virulentem Katzenfieber- (Agranulozytose) Virus durch Reihenpassage in katzenembryonaler Zellenkultur hat eine lebende Vakzine produziert, die antigen sowohl wie immunisierend ist. 相似文献

Antibiotic Resistance in Staphylococcus intermedius Isolated from Cases of Pyoderma in the Dog 总被引：1，自引：0，他引：1
Abstract— A study was made of the microbial flora of pyoderma in dogs to determine microbial species and, for staphylococci, the antibiotic resistance patterns in relation to therapy. Samples from 120 cases of canine pyoderma yielded 96 isolates of Staphylococcus intermedius, 17 samples yielded only Gram-negative bacilli and seven gave no aerobic bacterial growth. Multiresistant staphylococci and Gram-negative bacilli were more common in samples from referred cases than from primary consultations and from deep rather than from superficial lesions. Prior antibiotic therapy had been more extensive in animals from which multi-resistant staphylococci or Gram-negative bacteria were recovered. Few plasmids mediating antibiotic resistance were carried by the S. intermedius isolates suggesting that resistance is chromosomally located. Résumé— Une étude de la flore microbienne des pyodermites chez la chien a éte entreprise pour déterminer les espèces microbiennes présentes et, pour les Staphylocoques, l'antibiorésistance en fonction des traitements. Les échantillons provenants de 120 cas de pyodermites canines ont permis d'isoler 96 fois un Staphylococcus intermedius, 17 fois uniquement des Gram négatifs en 7 fois aucune bactérie aérobie. Les staphylocoques multirésistants et les bacilles Gram négatifs étaient plus fréquents dan les cas référés que dans les cas vus pour la premiére fois et plus souvent lors de pyodermite profande que lors de pyodermite superficielle. L'antibiothérapie avait été plus importante chez les animaux chez lesquels des bactéries Gram négatives et des Staphylocoques multirésistants ont été isolées. Quelques plasmides médiateurs d'une antibiorésistance ont été isolés, suggérant que celle-ci est d'origine chromosomique. Zausammenfassung— Bei 120 Proben von kaniner Pyodermie wurde in 96 Fällen Staphylococcus intermedius und in 17 Fällen ausschließlich Gram-negative Bacillus-Arten isoliert. Bei 7 Proben trat kein Wachstum aerober Bakterien ein. Multiresistente Staphylokokken und Gram-negative Bacillus-Arten waren in den Proben von öberweisungsfällen häufiger als in denen von Erstkonsultationen, ebenso kamen sie in tiefen Läsionen öfter vor als in oberflächlichen. Tiere, bei denen multiresistente Staphylokokken oder Gram-negative Bakterien entdeckt wurden, hatten eine umfassendere vorausgegangene antibiotische Therapie erhalten. Da Isolate von S. intermedius einige Plasmide enthielten, die die Antibiotikaresistenz übermitteln, ist anzunehmen, daß die Resistenz in den Chromsomen lokalisiert ist. Resumen Un estudio de la flora microbiana del pioderma canino fué llevado a cabo para determinar las especies microbianas, y la resistencia a antibióticos de los stafilococos en relación con la terapia utilizada. En 120 muestras de pioderma canino se aislaron 96 Staphylococcus intermedius; en 17 muestras, solamente bacilos gran negativos; y en 7, no se logró el cultivo de bacterias aeróbicas. También se observó que los stafilococos multiresistentes y los bacilos gram negativos eran mucho más comunes en muestras de casos referidos, que aquellos procedentes de primera consulta, y también más frecuentemente de lesiones profundas, que de lesiones superficiales. La terapia con antibióticos instaurada previamente había sido más extensiva en muestras de donde se aislaron stafilococos con multiresistencia o bacilos gram negativos. Los S. intermedius aislados contenían unos plásmidos mediadores de resistencia, lo cual sugirió la posibilidad de la ubicación cromosómica de la resistencia bacteriana. 相似文献

Objective —To report a ventral abdominal approach and a ligating loop technique for laparoscopic cryptorchidectomy in horses.
Study Design —Prospective.
Sample Population—Six horses, aged 1 to 5 years, with retained testes.
Methods —One laparoscopic portal and three to four instrument portals were used for ventral abdominal laparoscopic cryptorchidectomy. Laparoscopic instruments were used to maneuver and secure the testis through a ligating loop (modified Roeder knot) that was secured from outside the abdominal cavity. Only minimal enlargement of one instrument portal was used to remove the testicle.
Results —Three horses were bilateral cryptorchids, and three were unilateral (left side, two; right side, one) cryptorchids. Operative time, defined as the time from laparoscope insertion to removal, ranged from 20 to 25 minutes for unilateral cryptorchids and from 40 to 50 minutes for bilateral cryptorchids.
Conclusions —The reported technique allowed decreased tension on the tissues during ligation and removal of the testis from the peritoneal cavity. Improved observation of the abdominal cavity, ligation security, shortened patient confinement time, and minimally invasive technique are all considered to be benefits of laparoscopic cryptorchidectomy.
Clinical Relevance —Direct observation of retained testes and intraabdominal castration are distinct advantages of the use of laparoscopy in horses that have had previous unsuccessful surgical attempts, horses with unknown histories that have retained testicular tissue, or bilateral abdominal cryptorchids. 相似文献

The objective was to characterize ultrasonographic changes in bowel wall thickness, contractility, degree of distension, luminal contents, and peritoneal fluid associated with exploratory celiotomy in normal ponies. Gastrointestinal ultrasonographic examination was performed in 14 ponies on days 1, 3, 5, and 7 after an exploratory celiotomy. Wall thickness, contractility, degree of distension, and luminal contents were recorded for the duodenum and jejunum. Stomach wall thickness and location, cecal wall thickness, and peritoneal fluid location and character were recorded. Peritoneal fluid was identified most frequently on day 1 (P=0.0005). Duodenal wall thickness was significantly decreased on day 7 compared with days 1, 3, and 5 suggesting inflammatory thickening postoperatively (P=0.005). Stomach wall thickness was decreased on day 1 compared with days 3, 5, and 7 (P=0.03). All measurements, however, were within normal limits. Hypocontractile segments of jejunum were most frequently identified on day 1 (P=0.02) and hypoechoic contents were identified most frequently in the jejunum on day 1 and the duodenum on day 3, suggesting mild functional ileus or enteritis in the early postoperative period. Our findings support that bowel handling during abdominal exploration causes minimal changes in bowel wall thickness, contractility, degree of distension, luminal contents, and peritoneal fluid. This study was performed in ponies without gastrointestinal disease and further studies are necessary in patients. 相似文献

Objective— To report a case of multiple acquired jejunal pseudodiverticula managed successfully by resection and jejunojejunostomy.
Study Design— Clinical report.
Animals— Arabian filly.
Methods— The filly was referred for signs of acute colic of several hours duration and had a 2-week history of inappetence and weight loss. Three meters of thickened, edematous, and dilated jejunum removed during exploratory celiotomy had an intussusception and numerous diverticula; jejunojejunostomy performed. The pathoanatomic diagnosis was proliferative enteropathy with pseudodiverticula formation and jejunal muscular hypertrophy and diverticulosis. The diverticula appeared to be acquired; however, the exact cause was not determined.
Results— There were no postoperative gastrointestinal complications and 1 year later, the filly was doing well.
Conclusion— Multiple acquired jejunal pseudodiverticula not associated with classic muscular hypertrophy can occur in young horses. Long-term prognosis seemingly can be excellent after resection and jejunojejunostomy.
Clinical Relevance— Compared with other reports of small intestinal diverticula in horses, this case is unique because it was not congenital or associated with classic muscular hypertrophy. 相似文献

The frequency of communication between the tarsometatarsal and distal intertarsal joints was investigated in 27 horses and 12 ponies. After the injection of diluted latex into the tarsometatarsal joints using the plantarolateral approach, the horses and ponies were walked for 200 meters. Latex was found in the distal intertarsal joints of 19 of 73 tarsi (26% communication) at necropsy. In 3 tarsi, latex was also found in the proximal intertarsal and tar-socrural joints. 相似文献
