STEPHEN D. GILSON DVM    DONALD L. PIERMATTEI DVM  PhD  DiplomateACVS  PETER D. SCHWARZ DVM  DiplomateACVS 《Veterinary surgery : VS》1989,18(2):114-122

Humeroulnar subluxation was treated surgically in 13 dogs with 18 affected elbows using a proximal osteotomy of the ulna that allowed the ulna to elongate dynamically. Distal humeroulnar subluxation was secondary to premature closure of the distal ulnar physis in 16 elbows. One distal subluxation was secondary to a radioulnar synostosis, and one proximal subluxation developed after premature closure of the distal radial physis. The mean follow-up time was 22 months. Twenty-eight percent of the elbows were judged to have excellent results, 22% good results, 50% fair results, and none was judged to have a poor outcome. The presenting lameness grade and the severity of preoperative and postoperative humeroulnar subluxation had significant correlations with the prognosis. Associated orthopedic abnormalities and complications of concurrent surgical procedures affected the outcome in several dogs. Overall, the dynamic proximal ulnar osteotomy was a simple and effective technique for the treatment of uncomplicated humeroulnar subluxation.  相似文献   

Clinical Evaluation of Three Surgical Methods for Treatment of Caudal Cervical Spondylomyelopathy of Dogs     

KENNETH A. BRUECKER DVM  MS    HOWARD B. SEIM III  DVM  DiplomateACVS STEPHEN J. WITHROW DVM  DiplomateACVS 《Veterinary surgery : VS》1989,18(3):197-203

Sixty-four dogs with caudal cervical spondylomyelopathy (CCSM) caused by chronic degenerative disc disease were treated with ventral decompression (n = 20), linear traction and interbody screw stabilization (n = 7), or linear traction and plastic plate stabilization (n = 37). Interbody screw stabilization was ineffective in treating CCSM because of an unacceptably high rate of implant failures. Ventral decompression or linear traction and plastic plate stabilization were effective in the treatment of most patients with mild to moderate neurologic deficits (neck pain, paraparesis, or ambulatory tetraparesis). Although these techniques were also used successfully in some patients with severe neurologic deficits (weakly ambulatory tetraparesis or nonambulatory tetraparesis), variable success rates and prolonged postoperative recovery periods were noted.  相似文献   

Surgical Management of Atlantoaxial Subluxation in 23 Dogs     

WILLIAM B. THOMAS DVM    DONALD C. SORJONEN DVM  MS  Diplomate ACVIM  STEPHEN T. SIMPSON DVM  MS  Diplomate ACVIM 《Veterinary surgery : VS》1991,20(6):409-412

Twenty-eight surgical procedures were performed in 23 dogs with atlantoaxial subluxation. Dorsal stabilization in seven dogs resulted in two recoveries and five failures of fixation. Ventral decompression and stabilization in 18 dogs resulted in eight recoveries and four failures of fixation. Six dogs died or were euthanatized within 7 days of ventral stabilization. Using either technique, four of seven nonambulatory dogs recovered.  相似文献   

Abdominal Wall Reconstruction with a Vascular External Abdominal Oblique Myofascial Flap     

LISA G. ALEXANDER DVM    MICHAEL M. PAVLETIC DVM  Dipiomate ACVS  STEPHEN J. ENGLER VMD 《Veterinary surgery : VS》1991,20(6):379-384

A myofascial island flap for abdominal wall reconstruction was based on the lumbar component of the external abdominal oblique muscle and supplied by a major neurovascular pedicle consisting of branches of the cranial abdominal artery, cranial hypogastric nerve, and a satellite vein. The flap was elevated and sutured into a 10 cm x 10 cm body wall defect in five dogs. The dogs were observed for 26 to 28 days. Abdominal wall contour and function were preserved. All dogs developed seromas, two of which became infected. One dog developed a hernia at the dorsal margin of the flap, which was repaired. At necropsy, there was no evidence of dehiscence in any of the dogs. Loose adhesions of omentum to the inner surface of the flap occurred in four dogs. Results of histologic examination confirmed the clinical impression of flap viability. The myofascial island flap has a wide range of mobility over the ventral and caudal areas of the abdomen and lateral thoracic wall. It has potential clinical use for reconstruction of defects within its arc of rotation.  相似文献   

Resident Dendritic Cells in the Epidermis: Langerhans Cells, Merkel Cells and Melanocytes     

STEPHEN D. WHITE  JULIE A. YAGER† 《Veterinary dermatology》1995,6(1):1-8

Résumé— En plus des kératinocytes, l'épiderme contient des cellules résidentes de morphologie dendritique. Ce sont principalement la cellule de Langerhans, la cellule de Merkel et le mélanocyte. Ces cellules ont des fonctions diverses dans le tégument. Le mélanocyte assure la pigmentation cutanée et la protection contre les radiations U.V., et pourrait intervenir également dans la modulation de l'inflammation cutanée. La cellule de Langerhans intervient dans la surveillance immunologique des surfaces corporelles ecternes. La cellule de Merkel a des fonctions neuroendocrines. Cet article donne un aperçu de la structure et de la fonction de ces trois importantes populations cellulaires dans la peau. [Resident dentritic cells in the epidermis: Langerhans cells, Merkel cells and melanocytes (Cellules dentritiques résidentes de l'épiderme: cellules de Langerhans, cellules de Merkel et mélanocytes). Resumen— La epidermis contiene, además de los queratinocitos, células résidentes de morfologia dendria dendritica. Estas son principalmente las células de Langerhans, las células de Merkel y los melanocitos. Estas células tienen varias funciones en el integumento. Los melanocitos se encargan de la pigmentación y protección de la piel contra la radiación ultravioleta y tarrtbién participan en la regulación de la inflamación cutánea. Las células de Langerhans ayudan en la regulación inmunológica en la superficie externa. Las células de Merkel tienen funciones neuroendocrinas. Esta revisión da un repaso general a la estructura y función de tres importantes células de la piel. [Resident dendsuitic cells in the epidermis: Langerhans cells, Merkel cells and Melanocytes (Células résidentes en la epidermis: células de Langerhans, células de Merkel y melanocitos). Abstract— In addition to the keratinocytes, the epidermis contains resident cells of dendritic morphology. These are principally the Langerhans cell, Merkel cell and melanocyte. These cells have a number of different functions in the integument. The melanocyte is responsible for skin pigmentation and protection against UV radiation, and may also play a role in the modulation of cutaneous inflammation. The Langerhans cell aids in the immunological monitoring of the body's external surfaces. The Merkel cell has neuroendocrine functions. This review gives an overview of the structure and function of these three important cells of the skin.  相似文献   

Abdominal Crisis in the Horse: A Comparison of Pre-Surgical Evaluation With Surgical Findings and Results     

STEPHEN B. ADAMS D.V.M.  C. WAYNE McILWRAITH B.V.Sc  M.S.  M.R.C.V.S. 《Veterinary surgery : VS》1978,7(3):63-69

The results of preoperative examination, surgical intervention and the outcome of 50 cases of acute abdominal crisis in the horse are presented. Pre-surgical parameters discussed in this correlative study include duration of the condition prior to sergery, pulse rate, packed cell volume (PCV), abdominal distention, intestinal motility and tympany, rectal findings, reflux of fluid after passage of a nasogastric tube, and abdominal paracentesis. A retrospective study was performed to evaluate the usefulness of each clinical parameter in deciding that a case was surgical, arriving at a specific pre-surgical diagnosis, and in giving a prognosis. Rectal examination was the single most useful diagnostic tool. Reflux of gastric fluid through the nasogastric tube usually indicated obstruction of the small intestine.  相似文献   

A possible mechanism for the selective herbicidal activity of iodide in relation to thiocyanate content     

N. H. STEPHEN  G. T. COOK  H. J. DUNCAN 《Weed Research》1979,19(6):395-398

In an in vivo study, the rate of iodide oxidation by horseradish peroxidase was found to be reduced by the addition of ammonium thiocyanate to the system. The seleetive herbicidal activity of sodium iodide towards dwarf bean, pea, kale and cabbage was tested while the poicnlial ihioeyanale conteni of these platits was measured, A good relationship between inereasmg thiocyanale content and inereasing resistance to iodide was observed.  相似文献   

CARDIOVASCULAR AND GASTROINTESTINAL RADIOGRAPHIC CONTRAST STUDIES IN THE HORSESHOE CRAB (LIMULUS POLYPHEMUS)     

TIM SPOTSWOOD  STEPHEN A. SMITH 《Veterinary radiology & ultrasound》2007,48(1):14-20

Survey and contrast radiographic studies of the cardiovascular and gastrointestinal systems of the American horseshoe crab (Limulus polyphemus) were undertaken using conventional and flouroscopic techniques. Normal gastrointestinal and cardiovascular structures were difficult to resolve on survey radiographs, but were well visualized with gastrointestinal follow through studies and angiography, respectively. All three contrast agents (iohexol, Gastrografin, and barium sulfate) used for the gastrointestinal studies varied minimally in their radiographic quality and transit times, and all appeared to be safe for use in the horseshoe crab.  相似文献   

Limb Salvage Surgery for Osteosarcoma of the Proximal Humerus: Outcome in 17 Dogs   总被引：1，自引：0，他引：1  

CHARLES A. KUNTZ DVM  MS  DACVS    TONIA L. ASSELIN BS    WILLIAM S. DERNELL DVM  MS  DACVS    BARBARA E. POWERS DVM  PhD  DACVP    RODNEY C. STRAW BVSC  DACVS  STEPHEN J. WITHROW DVM  DACVS  DACVIM 《Veterinary surgery : VS》1998,27(5):417-422

Objective —To describe function and identify factors that affect outcome in dogs undergoing limb salvage surgery for osteosarcoma (OS) of the proximal humerus.
Study Design —A retrospective study of dogs in which OS of the proximal humerus was treated with limb salvage surgery.
Animals —17 client-owned dogs.
Methods: Records were analyzed for functional outcome, recurrence, metastasis, and survival.
Results —Outcome was good to excellent in 12% of dogs. Recurrence, metastasis, and survival were significantly affected by completeness of surgical margins. Double plating of the distal allograft-host junction significantly reduced frequency of biomechanical failure.
Conclusions —Limb salvage surgery for OS of the proximal humerus did not result in acceptable function and was fraught with postoperative complications. Outcome was significantly affected by completeness of surgical margins.
Clinical Relevance —Limb salvage surgery for OS of the proximal humerus in dogs cannot be recommended until improvement in functional outcome and reduction in postoperative complications can be achieved. The dependence of outcome on completeness of surgical margins supports aggressive en bloc resection and marking and evaluating surgical margins.  相似文献
