Dermovilite exsudativa vegetante crônica em equino - relato de caso / Chronic equine proliferative pododermatitis - case report

A dermovilite exsudativa vegetante crônica (DEVC) é uma afecção que acomete os cascos de equinos, comprometendo seu bem-estar e que ainda é subdiagnosticada devido à similaridade com outras doenças. O presente trabalho relata o diagnóstico clínico da DEVC em um paciente equino atendido no Ambulatório de Grandes Animais do Hospital Veterinário da Universidade Federal Rural de Pernambuco. O paciente de doze anos de idade, 386 kg e sem raça definida apresentava histórico de crescimento irregular dos cascos, com odor fétido, presença de tecido esponjoso nas ranilhas e claudicação. Foi realizado o debridamento das lesões, antissepsia dos cascos, colocação de bandagens acolchoadas e impermeabilização, além de administração de penicilina benzatina e flunixina meglumina. Apesar das lesões patognomônicas possibilitarem o diagnóstico clínico de DEVC, ainda é necessária a ampliação dos conhecimentos a seu respeito para possibilitar a sua prevenção e diagnóstico.

Chronic equine proliferative pododermatitis is a condition that affects the horse hooves, compromising their welfare. Despite its clinical importance, it is still underdiagnosed due to its similarity to other diseases. Therefore, the present study aimed to report the clinical diagnosis of this disease in an equine patient seen at the Ambulatory of Large Animals of the Veterinary Hospital of the UFRPE. The twelve-year-old patient, 386 kg body weight and mixed-race, presented a history of hooves with irregular growth and malodorous odor, presence of spongy tissue in the frogs and lameness. Initial treatment consisted of debridement of the lesions, antisepsis of the hooves, the placement of padded bandages, waterproofing, and the administration of Benzathine penicillin and flunixin meglumine. Despite the pathognomonic lesions making possible the clinical diagnosis of this disease, it is still necessary to expand knowledge about it, for the improvement of its prevention and diagnosis

Biochemical profile and productive performance in dairy cows with lameness during postpartum period

Background: Lameness in dairy cows is classified as a gait change caused by multifactorial process. The phase of theperipartum causes intense physiological changes for the adaptation of late gestation and onset of lactation. The aim of thisstudy was to characterize the changes in the biochemical profile and productive performance in dairy cows with lamenessduring postpartum period.Materials, Methods & Results: This study was conducted at the University of São Paulo farm, in Pirassununga, São PauloState, Brazil, from January to March 2017. A total, of 48 multiparous (2 to 3 lactations and 3-4 years old) dairy cows,that had the milk production of 9,200 kg/ dairy cow in a period of 305 days in the previous lactation, were included in thestudy. All cows were managed under the same conditions and nutritional regimen. Evaluation of body condition score wasperformed by a single person on -18, -12, -8, -5, and -2 days before parturition, at parturition, and on days 1, 7, 14, 21,30, 45 and 60 after parturition. Milk production was recorded on days 7, 14, 21, 30, 45 and 60 after parturition and savedin the software program. Blood samples were performed on -18, -12, -8, -5, and -2 days before parturition, at parturition,and on days 1, 7, 14, 21, 30, 45 and 60 after parturition. Blood samples were assayed for albumin, calcium, cholesterol,triglycerides, non-esterified fatty acids, β-hydroxybutyrate, urea, creatinine, gamma-glutamil-transferase and total proteinconcentrations. Dairy cows were divided into a lame group (11) and normal group (37) based on locomotion score fromparturition to seven days postpartum. Lame cows was classified if their score was > 2, and normal cows was classified iftheir score was ≤ 2 and free of any disease. Dairy cows that suffer by any health disorder other than lameness were excludedfrom this study. Cow diagnosed with lameness outside the diagnostic period were excluded from this study...

Comparison of thermographic imaging and other diagnostic techniques in diagnosis of cattle with laminitis

Background: Lameness results in major economic losses on dairy farms. The proportion of lameness in cows are between 4-55%, the origin of 90% lameness are caused by foot diseases. Hoof abnormalities such as laminitis are major contributors to lameness. Aim of the study, compared with thermographic imaging (IRT) and radiographic, magnetic resonans (MR), computer tomography (CT), histopathological analysis on the diagnosis of laminitis.Materials, Methods & Results: Preliminary, the animals (20 Holstein-Fresian) were selected by lameness examination for evaluation of the for any obvious signs of disease. The animals were examined when rising and walking of the free stalls. Walking was very painful and clinical symptoms of general distress become present for laminitic group. The cows were scored on a 1 to 5 scale for their locomotion (1 = normal locomotion; 5 = severely lame). Thermographic examinations were performed the all animals after the routine clinical examination methods. The infrared images were taken from the dorsal view of all hoovesto monitor the temperature of coronary band. All images were scanned using a hand-held portable infrared camera (Wahl, Thermal Imager HSI3000 Series), which was calibrated to ambient temperature and absorptive conditions. Incentives radiological examinations, dorso-palmar and latero-medial shooting was done for using of (Regius Model 110 Konica, Minolta) 70 kV and 30 mAs for each claws. MRI images of all isolated digits were performed at the Department of Radiology, by using Siemens Symphony Erlangen, Germany. Continuous series of transversal, sagital and dorsoplantar scan were obtained from all digit. Computer tomography (CT), isolated digits were performed at the Imaging Department of Radiology, by using Siemens Symphony Erlangen, Germany.[...]

Neurectomia digital palmar em equinos / Digital palmar neurectomy in horses / Neurectomia digital palmar en caballos

A neurectomia digital palmar é utilizada em animais que apresentam dor devido às doenças degenerativas podais que não respondem ao tratamento conservativo. Diversas técnicas de neurectomia foram desenvolvidas com objetivo de obter menor trauma cirúrgico, evitando o desenvolvimento de neuroma doloroso,considerado uma das principais complicações da secção nervosa. Para os animais atletas registrado sem associações de criadores, a neurectomia é considerada doping por não tratar a doença de base da claudicação,impedindo-o de participar de eventos esportivos. A presente revisão bibliográfica abrange estudos das diferentes técnicas de neurectomia, avaliando suas indicações, vantagens e desvantagens. As técnicas relatadas apresentam diferentes resultados quando comparadas em relação ao tempo e taxa de formação do neuroma, podendo este ser doloroso ou não.

Palmar digital neurectomy is utilized in horses suffering from degenerative and painful conditionslocalized in the foot, unresponsive to medical and conservative forms of therapy. Different techniques of palmar digital neurectomy were developed in order to minimize surgical trauma and avoid the most commoncomplication associated with nerve transection, that is painful neuroma. Neurectomy is considered doping inanimais registered in breeders' associations, once it does not represent a treatment for the underlying condition,and horses that have had surgery are not allowed to compete. This literature review describes different neurectomy techniques, evaluating their indications, advantages and complications. Presented techniques vary in results when rate and time to neuroma formation are considered, be it painful or not.

Ativação de plaquetas de eqüinos com laminite induzida e tratados com ketoprofeno, fenilbutazona e flunixin meglumina / Platelets activation in equine with induced laminitis and treated with ketoprophen, phenylbutazone and flunixin meglumin

Avaliou-se a ativação de plaquetas em 20 eqüinos com laminite induzida, tratados com ketoprofeno, fenilbutazona e flunixin meglumina. As alterações de plaquetas incluíram mudança de forma, alteração da relação entre os eixos maior e menor, aumento de perímetro, emissão de pseudópodes, aumento no número de alfa-grânulos e de grânulos de glicogênio e redução no número de gama-grânulos. As plaquetas de eqüinos, quando ativadas, apresentaram perfil de organela diferente de plaquetas normais, e as drogas antiinflamatórias, não-esteroidais, demonstraram atividade na ativação plaquetária de eqüinos in vivo. O flunixin meglumina apresentou melhor atividade em modular a ativação plaquetária de eqüinos in vivo do que a fenilbutazona e o ketoprofeno.(AU)

The platelets activation from 20 equines submitted to laminitis induction and treated with ketoprophen, phenylbutazone and flunixin meglumin, was evaluated. The platelets changes included shape change, altered relations between axis, increased perimeter, pseudopodia, increased alpha-granules and glycogen-granules, and decreased in gamma-granules. Platelets when activated present a different organelle profile than normal ones. Equine activated platelets had different organelles profile than normal ones, and anti-inflammatory drugs can modulate the platelet activation, being the flunixin meglumin better than phenylbutazone and ketoprophen.(AU)

Perdas econômicas ocasionadas pelas enfermidades podais em vacas leiteiras confinadas em sistema free stall / Economic losses caused by sequels of lameness in free-stall-housed dairy cows

Avaliaram-se 55 casos clínicos de manqueira em um rebanho de 100 vacas em lactação confinadas em sistema de free stall, durante um ano. As afecções mais observadas foram abscessos de sola e talão, úlcera de sola e dermatite digital que representaram 87,3% (48/55) das ocorrências. O tratamento empregado mostrou-se satisfatório com recuperação de todos os animais tratados com 24,5 dias, em média, sem ocorrência de descarte. O custo com tratamento e redução na produção de leite foi de US$95.80/vaca, o que representou US$52.69 por vaca alojada/ano. Quando se computaram as perdas reprodutivas e com mastite, obtiveram-se US$227.94 adicionais em vaca com problema de manqueira. O custo adicional anual total no rebanho decorrente de seqüelas de manqueira foi de US$12,536.70, que representou US$125.36 por vaca alojada/ano. O período de serviço e o número de serviços por concepção em vacas com problemas de manqueira e normais foram 266 e 200,5 dias e 4,3 e 3,3 serviços, respectivamente. As incidências de mastite e metrite na mesma ordem de citação anterior foram 60% e 25% e 29% e 12,5%.(AU)

Fifty-five clinical cases of lameness were evaluated in 100 lactating cows housed in a free-stall system during one year. The most observed affections were sole and heel abscesses, sole ulcers and digital dermatitis that accounted for 87.3% (48/55) of the occurrences. The treated cows showed satisfactory recovery (24.5 average days) without culling. The total individual cost including treatment and reduction of milk production was US$95.80/cow or US$52.69 per housed cow/year. When reproductive losses and mastitis were considered an additional cost of US$227.94 per lameness cow was estimated. The total additional annual cost from sequels of lameness was US$12.536.70 or US$152.36 per housed cow/year. The number of days open and the number of services per conception in lameness and normal cows were, respectively, 266 and 200.5 days and 4.3 and 3.3 services. Mastitis and metritis incidences, regarding the same animals, were, respectively, 60% and 25% and 29% and 12.5%.(AU)
