Survey of Integrative Veterinary Medicine Training in AVMA-Accredited Veterinary Colleges.

A survey approved by the Association of American Veterinary Medical Colleges was sent to the academic deans of all 49 accredited veterinary colleges to obtain information on educational programs offered in integrative veterinary medicine (IVM). Results were compared to a previous survey with a similar design performed 7 years earlier. Survey responses were received from 43 of 49 institutions (87.8%). Thirteen respondents (30.2%) reported offering a formal course in IVM, 33 (76.7%) offered some level of instruction in the curriculum, and 32 (74.4%) provided clinical services in IVM. The most common IVM topics covered in the curriculum were rehabilitation and acupuncture. Dedicated courses in IVM had decreased since the previous survey, although faculty trained in at least one aspect of IVM increased. Clinical services incorporating IVM were present in the majority of veterinary teaching hospitals. Further investigation is required to determine the effectiveness of current IVM training in preparing veterinary graduates to discuss or utilize IVM in practice.

Effects of laser power, wavelength, coat length, and coat color on tissue penetration using photobiomodulation in healthy dogs.

Photobiomodulation is an accepted regenerative medicine treatment modality used to stimulate tissue repair, mediate inflammation, and improve mobility in humans and animals. The objective of this study was to assess the influence of laser power and wavelength, coat length and color, and shaving on in-vivo photon delivery by therapeutic laser in dogs. Forty-seven dogs of various breeds and coat colors (17 black, 15 brown, and 15 white) and with varying coat lengths were assessed with 2 commercially available veterinary lasers. Photons were delivered to the lateral aspect of the inguinal fold and calcaneal tendon, with direct penetration through the dermis, as well as dermis and tendon, as measured with a thermopile laser sensor. Significant impacts on laser transmission were noted for laser power (P = 0.001), wavelength (P < 0.002), coat color (P < 0.001), and shaved coat (P < 0.001). Percent transmission was higher for a class IV 810/980 nm wavelength laser at 0.5 W than for a class IIIb 904 nm laser (P < 0.001). There was a significant difference between transmission of photons among white, brown, and black coats, with less transmission noted with increasing coat pigment (P < 0.001). Transmission was greater at higher power levels (3 W, 5 W) Results showed significant differences in laser transmission for all variables assessed, with the exception of coat length, which was not a significant predictor of laser transmission. As transmission was significantly reduced in darker and unshaved areas, higher power lasers may be necessary for darker pigmented dogs and shaving of hair is recommended before laser therapy.

La photobiomodulation est une modalité de traitement médical régénérateur acceptée utilisée pour stimuler la réparation tissulaire, diminuer l'inflammation et améliorer la mobilité chez les humains et les animaux. L'objectif de la présente étude était d'évaluer l'influence de la puissance et de la longueur d'ondes du laser, la couleur et la longueur du pelage, et le rasage sur la livraison in vivo de photons par un laser thérapeutique chez des chiens. Quarante-sept chiens de races diverses et de couleurs de pelage différentes (17 noirs, 15 bruns et 15 blancs) et avec des longueurs de pelage différentes furent évalués avec deux lasers vétérinaires disponibles commercialement. Les photons étaient délivrés sur l'aspect latéral du repli inguinal et sur le tendon calcanéen, avec pénétration directe à travers le derme, ainsi qu'à travers le derme et le tendon, tel que mesuré avec un capteur laser thermopile. Des impacts significatifs sur la transmission du laser furent notés pour la puissance du laser (P = 0,001), la longueur d'ondes (P < 0,002), la couleur du pelage (P < 0,001) et le rasage du poil (P < 0,001). Le pourcentage de transmission était plus élevé pour un laser de classe IV à longueur d'ondes 810/980 nm à 0,5 W que pour un laser de classe IIIb à longueur d'ondes de 904 nm (P < 0,001). Il y avait une différence significative entre la transmission des photons parmi les pelages blancs, bruns et noirs, avec moins de transmission notée avec une augmentation de la pigmentation du pelage (P < 0,001). La transmission était supérieure à des niveaux de puissance plus élevés (3 W, 5W). Les résultats montrent des différences significatives dans la transmission du laser pour toutes les variables mesurées, à l'exception de la longueur du pelage, qui n'était pas un prédicteur significatif de la transmission du laser. Étant donné que la transmission était réduite significativement dans les endroits plus foncés et non-rasés, des lasers de plus forte puissance pourraient être nécessaires pour des chiens à pigmentation plus foncée et le rasage des poils avant la thérapie au laser est recommandé.(Traduit par Docteur Serge Messier).

Internet Survey of Participant Demographics and Risk Factors for Injury in Flyball Dogs.

Background: Injury risk in canine sprinting sports, such as greyhound racing and agility, have been previously documented through various surveys. Flyball, another sprinting canine sport with similar athletic requirements to agility, has yet to be assessed for factors associated with injury. The aim of this study was to determine injury prevalence and assess for risk factors for injury in flyball dogs. Methods: Survey data from 375 flyball participants was collected and analyzed. Data collected included patient-specific variables, equipment use, training/competition practices, and injury occurrence and localization. Univariate analysis was utilized for all variables of interest, followed by backwards nominal logistic regression to identify variables associated with increased risk of injury, with a p < 0.05 defined as significant. Results: Thirty-nine percent of dogs incurred at least one injury with 172 injuries reported. Injuries to the limbs were common (30.8% affecting forelimbs, 25.6% affecting hindlimbs), with the paw or nail the most frequently reported injured area (19.2%). Only protective wrap use and age were significantly associated with injury in the final nominal regression model (p < 0.01). A biphasic injury rate with more injuries in younger dogs was observed, and injuries peaked by 6 years of age. Use of carpal wraps was positively associated with increased injury risk. Conclusions: These findings suggest an association between younger dogs and greater risk of injury, as well as identify a need to further investigate the utilization of wraps and potential association between injury risk among flyball participants.

Cytologic identification of fungal arthritis in a Labrador Retriever with disseminated Talaromyces helicus infection.

An 8-year-old, neutered male Labrador Retriever presented with acute forelimb lameness. Clinical signs progressed over one week. On physical examination, right cubital joint effusion and bilateral axillary lymphadenomegaly were noted, and severe internal lymphadenomegaly was observed ultrasonographically. Granulomatous lymphadenitis with intralesional fungi was noted cytologically, and the dog was ultimately diagnosed with disseminated Talaromyces helicus infection via PCR of a pure isolate. Extensive medical therapy was pursued, and months later, an arthrocentesis was performed due to continued lameness and severe cubital joint effusion. The synovial fluid contained increased numbers of neutrophils, macrophages, and multinucleated giant cells. Frequent fungal hyphae were found both intracellularly and extracellularly. These basophilic organisms were 2-4 µm in width with internal eosinophilic granules, roughly parallel walls, and occasional to frequent septa. Round to oval yeast-like forms with thin, clear halos were also occasionally identified. Due to the severity of clinical signs, the right thoracic limb was amputated. Histologic examination of the cubital joint revealed marked granulomatous synovitis, fasciitis, panniculitis, and osteomyelitis, all with intralesional fungi. Talaromyces helicus is a very rare cause of disease, reported only in one other dog. Granulomatous lymphadenitis appears to be a feature of this disease, but this report is the first to describe a significant synovial component.

Biomechanical comparison of a modified three-loop pulley technique and a three-level self-locking technique for repair of patellar tendon rupture in dogs.

OBJECTIVE: To compare use of a 3-level self-locking suture (3LSLS) technique with use of a previously described modified 3-loop pulley (M3LP) technique to repair rupture of the proximal aspect of patellar tendons in limbs from canine cadavers. SAMPLE: Paired hind limbs of 6 adult mixed-breed dogs. PROCEDURES: A limb from each pair was randomly assigned to be repaired by the 3LSLS technique or M3LP technique with size-2 ultrahigh-molecular-weight polyethylene and size-0 monofilament polypropylene suture, respectively. Limbs were prepared, and each patellar tendon was transected at a site chosen to simulate rupture at the proximal aspect. Tendons were repaired with the assigned techniques and mechanically tested with a biaxial servohydraulic test system; the clamp was distracted until the repair failed. Force at 1 -mm gap formation, 3-mm gap formation, and repair failure and gap size at failure were measured and compared between methods. Mode of failure was recorded. RESULTS: There was no significant difference between methods for the force required to produce a 1 - or 3-mm gap in the repair. The 3LSLS technique required a significantly higher load for complete failure; gap formation immediately before failure was significantly greater for this method than for the M3LP technique. Four of 6 repairs with the M3LP technique and 0 of 6 repairs with the 3LSLS technique failed by suture breakage. CONCLUSIONS AND CLINICAL RELEVANCE: The 3LSLS technique with size-2 ultrahigh-molecular-weight polyethylene suture was as effective at resistance to 1 - and 3-mm gap formation as the M3LP with size-0 monofilament polypropylene suture.

Comparison of pentobarbital-phenytoin alone vs propofol prior to pentobarbital-phenytoin for euthanasia in 436 client-owned dogs.

OBJECTIVE: To report the incidence of adverse events during euthanasia of client-owned dogs administered either intravenous pentobarbital/phenytoin (PP) or PP after propofol delivery. DESIGN/SETTING: Prospective, observational, multi-site study. ANIMALS: Four hundred thirty-six dogs undergoing client-elected euthanasia over a 1-year period. INTERVENTIONS: Interventions included placement of an IV catheter and delivery of euthanasia agents (PP for the PP group, propofol followed by PP for the propofol group). Seven pre-determined adverse events were recorded: agonal breaths, urination, defecation, vocalization, muscle activity, dysphoria, and catheter complications. Euthanasia scores for each patient were defined as the sum of all adverse events (0-7) the patient exhibited. MEASUREMENTS AND MAIN RESULTS: Two hundred thirty-six dogs were in the PP group and 200 dogs were in the propofol group. No significant differences were detected in the dose of PP administered (166.9 ± 105.6 mg/kg for PP group, 182.6 ± 109.8 mg/kg for propofol group). Propofol dogs received 4.5 ± 2.9 mg/kg propofol. The incidence of ≥ 1 adverse event was 35.2% in the PP group and 26.5% in the propofol group (P = 0.052). Mean euthanasia scores (0.47 PP group, 0.32 propofol group) were not significantly different (P = 0.08). Propofol significantly reduced the incidence of muscle activity (6% vs. 14%, odds ratio 0.39; P = 0.0079). CONCLUSIONS: There was no difference in the likelihood of the studied adverse events during client-elected euthanasia in dogs when propofol was used prior to PP. There was a significant reduction in perimortem muscle activity if propofol was given prior to PP.

Obesity, Exercise and Orthopedic Disease.

Osteoarthritis is common among aging canine and feline patients. The incidence and severity of clinical lameness are closely correlated to body condition in overweight and obese patients. Excessive adiposity may result in incongruous and excessive mechanical loading that worsens clinical signs in affected patients. Data suggest a potential link between adipokines, obesity-related inflammation, and a worsening of the underlying pathology. Similarly, abnormal physical stress and generalized systemic inflammation propagated by obesity contribute to neurologic signs associated with intervertebral disc disease. Weight loss and exercise are critical to ameliorating the pain and impaired mobility of affected animals.
