A surveillance system for diseases of companion animals in the Veneto region (Italy).

Experts and international public health organisations stress the lack of surveillance systems for companion animal diseases and the need to implement such surveillance as a priority of the 'One Health' perspective. This paper presents the features of a system for the collection, analysis, interpretation and dissemination of data regarding the health status of pets in the Veneto region (Italy). The system involved the construction of a Web-based database containing the diagnoses of transmissible and non-transmissible diseases of dogs and cats made by veterinarians in their practices, hospitals, kennels and catteries. Each diagnosis constitutes a single record, also containing data on the identification of the individual animal and on several characteristics of epidemiological relevance. The World Health Organization (WHO) 10th revision of the International Classification of Diseases (ICD-10) for human diseases has been adapted to canine and feline diseases to standardise the diagnostic nomenclature. Software has been specifically created for online data entry and data management. The first results show that the main disorders were digestive (21%), dermatological (18%) and cardiovascular (11%) among 1,087 diagnostic records in dogs, and digestive (23%), dermatological (15%) and urinary (14%) among 289 diagnostic records in cats. The main causes of death are represented by cardiovascular (21%) and gastrointestinal (21%) diseases in dogs and by urinary (31%) disorders in cats. At present, no institutional surveillance system for companion animal health exists in Italy, and veterinarians joining this project and sharing the outcomes of their clinical activity are acting on a voluntary basis.

Aussi bien les experts que les organisations internationales oeuvrant dans le domaine de la santé publique soulignent l'absence de systèmes de surveillance dédiés aux maladies des animaux de compagnie, alors que la mise en place de cette surveillance constitue une priorité dans une perspective « Une seule santé ¼. Les auteurs décrivent les caractéristiques d'un système introduit en Vénétie (Italie) pour collecter, analyser, interpréter et diffuser des données sur la situation sanitaire des animaux de compagnie. Le système repose sur une base de données en ligne alimentée par les rapports de diagnostic sur les maladies transmissibles et non transmissibles des chiens et des chats établis par les vétérinaires dans leur cabinet, à l'hôpital ou dans les élevages ou pensions pour chiens et chats. Chaque diagnostic fait l'objet d'une notification spécifique où sont également consignées les données d'identification individuelle de l'animal et les caractéristiques pertinentes au plan épidémiologique. La classification internationale statistique des maladies (ICD­10) de l'Organisation mondiale de la santé (OMS), qui concerne les maladies humaines, a été adaptée aux maladies des chiens et des chats afin d'utiliser une nomenclature standardisée des diagnostics. Un logiciel spécifique a été créé pour la saisie en ligne des données et leur gestion. D'après les premiers résultats, les principales affections diagnostiquées étaient, chez le chien (sur 1 087 rapports de diagnostic), des maladies digestives (21 %), dermatologiques (18 %) et cardio-vasculaires (11 %) et, chez le chat (sur 289 rapports de diagnostic), des maladies digestives (23 %), dermatologiques (15 %) et urinaires (14 %). Les principales causes de mortalité étaient respectivement les maladies cardio-vasculaires (21 %) et gastro-intestinales (21 %) chez le chien et les maladies du système urinaire (31 %) chez le chat. À l'heure actuelle, aucun système institutionnel de surveillance n'est en place en Italie pour les animaux de compagnie, de sorte que les vétérinaires qui participent à ce projet et partagent leurs résultats cliniques le font sur une base volontaire.

Tanto especialistas como organizaciones internacionales dedicadas a temas de salud pública hacen hincapié en la ausencia de sistemas de vigilancia de las enfermedades de los animales de compañía y en la necesidad de instaurar tal vigilancia como elemento prioritario de los planteamientos de «Una sola salud¼. Los autores presentan las características de un sistema destinado a reunir, analizar, interpretar y difundir datos sobre el estado de salud de los animales de compañía en la región italiana del Veneto. Para instituir ese sistema se creó una base de datos en línea que centraliza información sobre los diagnósticos de enfermedades transmisibles y no transmisibles de perros y gatos realizados por veterinarios en el ejercicio de su labor en consultorios, hospitales y residencias caninas y felinas. Cada diagnóstico constituye un registro único, que también contiene datos sobre la identidad del animal en cuestión y sobre una serie de aspectos de importancia epidemiológica. Con objeto de normalizar la nomenclatura de diagnóstico se adaptó a las enfermedades caninas y felinas la Clasificación Internacional de Enfermedades, décima revisión (CIE­10), de la Organización Mundial de la Salud (OMS), que se aplica a las enfermedades humanas. También se crearon programas informáticos destinados específicamente a la introducción de datos en línea y a su gestión. Los primeros resultados muestran que los principales trastornos en los perros, de los 1.087 diagnósticos registrados, fueron los digestivos (21%), seguidos de los dermatológicos (18%) y los cardiovasculares (11%). En el caso de los gatos, con 289 diagnósticos registrados, las dolencias más importantes fueron las digestivas (23%), las dermatológicas (15%) y las urinarias (14%). En el perro, las principales causas de mortalidad fueron las enfermedades cardiovasculares (21%) y gastrointestinales (21%), y en el gato las patologías urinarias (31%). Actualmente no existe en Italia ningún sistema institucional de vigilancia de la salud de los animales de compañía, y los veterinarios que participan en este proyecto y comparten los resultados de su praxis clínica lo hacen con carácter voluntario.

Bovine xenograft application for treatment of a metatarsal nonunion fracture in an alpaca (Vicugna pacos).

CASE HISTORY: A 15-year-old female huacaya alpaca (Vicugna pacos) was referred because of a non-weight-bearing lameness (4/4) in the left pelvic limb caused by a grade three open metatarsal fracture. The referring veterinarian treated the fracture with conservative management using bandages, but it progressively evolved to a non-union. CLINICAL FINDINGS AND DIAGNOSIS: Clinical examination revealed external wounds on the medial and lateral surfaces of the metatarsus. Radiographs confirmed an open, nonarticular, displaced, diaphyseal fracture of the left metatarsus. TREATMENT AND OUTCOME: Cancellous bone was sourced from bovine proximal and distal femur epiphyses, followed by a thermal shock procedure to achieve decellularisation, to produce a xenograft. Open reduction and internal fixation of the fracture using locking plates was performed. Alignment of the fracture fragments was corrected and the xenograft was placed at the debrided fracture site to stimulate and harness osteogenesis in situ. Clinical and radiographic follow-up was performed up to 40 weeks postoperatively. Clinical evaluations revealed that the alpaca gradually increased weight bearing following bandage removal 10 days after surgery. Serial radiographs showed correct alignment of the left metatarsus, progressive bone modelling and, complete bone union at 12 weeks. Ten months postoperatively the alpaca showed no signs of lameness and resumed normal activity. CLINICAL RELEVANCE: For management of a metatarsal non-union, a combination of bovine xenograft application and angular stable internal fixation progressed toward an excellent long-term recovery.

Pharmacokinetics of gallium nitrate after oral administration in adult horses--pilot study.

Gallium (Ga), a metal in group IIIA of the periodic table, has shown a remarkable activity against bone resorption and could therefore possibly prove useful in the treatment of certain diseases in sport horses, for example navicular disease. The aim of this study was to gain more information concerning the kinetics of Ga after oral administration of gallium nitrate (GaN) in adult horses. Six horses received a single dose of 10 mg/kg of GaN mixed with the food ration. Absorption was slow (T(max) = 10 ± 3 h, T(½abs) = 2 ± 0.8 h), and a C(max) of 26 ± 11 µg/L was achieved. Excretion followed a one-phase elimination model, with a long half-life (T(½el) = 52 ± 14 h). By means of a mathematical model, we estimated that the plasmatic levels should reach 93 µg/L (1.33 µm) at steady state, following the repeated daily administration of 10 mg/kg of GaN. A three times lower concentration has been demonstrated as effective in inhibiting the osteolytic activity of osteoclasts in vitro. The results of this study suggest that the administration of oral GaN at a rate of 10 mg/kg per day may be considered for future clinical studies.

Nerve growth factor concentrations in the synovial fluid from healthy dogs and dogs with secondary osteoarthritis.

OBJECTIVE: To measure the concentrations of nerve growth factor (NGF) in the synovial fluid from normal dogs and dogs with osteoarthritis (OA) secondary to common joint disorders. METHODS: Nerve growth factor synovial concentrations were measured by ELISA assay in 50 dogs divided into three groups: 12 healthy, 16 affected by acute lameness within seven days before enrolment, and 22 with chronic lameness persisting by more than one month before enrolment and accompanied by radiological signs of OA. Both acute and chronic lameness were secondary to orthopaedic diseases involving the shoulder, elbow and stifle joints. Nerve growth factor synovial concentrations were compared between means for healthy and acute groups and between the three groups using an F-test. Significance level was set at p <0.05. RESULTS: Nerve growth factor was detected in all canine synovial fluid samples. However, the mean synovial NGF concentration of healthy dogs (3.65 ± 2.18 pg/ml) was not significantly different from the mean value in dogs with acute lameness (6.45 ± 2.45 pg/ml) (p = 0.79). Conversely, the mean synovial NGF concentration in dogs with chronic lameness (20.19 ± 17.51 pg/ml) was found to be significantly higher than that found in healthy dogs (p <0.01). CLINICAL SIGNIFICANCE: This study demonstrates for the first time the presence of NGF in canine synovial fluid and its increased concentrations in dogs with chronic lameness compared to healthy dogs and dogs with acute lameness. The association between chronic lameness and raised synovial concentrations may suggest an involvement of NGF in OA inflammation and chronic pain.

Dual-energy X-ray absorptiometry in canine legg-Calvé-Perthes disease.

Radiographic examination and subsequent dual-energy X-ray absorptiometry scans of the hips were performed in seven dogs with monolateral Legg-Perthes-Calvé disease to quantify bone changes produced by osteonecrosis in the proximal femur on the affected and unaffected side. All dogs were found to be affected with grade 2 and 3 of the radiographic classification proposed by Ljunggren. Bone mineral density (g/cm(2)) of the femoral neck and proximal femoral metaphysis were evaluated on the affected and unaffected side; we detected no differences in bone mineral density for both regions of interest within the population studied in relation to gender, body weight and side analysed nor between the affected and the unaffected limb. We therefore assume that radiographic areas of decreased density in the proximal femoral epiphysis during chronic stages of Legg-Calvé-Perthes disease do not alter the global mineral content of the scanned region.
