Desvio angular tibial varo bilateral em dachshund: relato de caso / Angular deviation pes tibial varus in Dachshund: case report

Varos tibial é um desvio angular decorrente do fechamento precoce parcial da linha fisária de crescimento do osso, levando a um desalinhamento articular com apoio e sobrecarga anormais, causando, secundariamente, osteoartrite, claudicação, luxação de patela, dor e problemas articulares. Neste relato, uma cadela da raça dachshund foi diagnosticada com tal afecção bilateralmente. Foi observado um desvio de ambos os membros posteriores aos 6 meses de idade. A confirmação da deformidade varo foi feita por meio do exame radiográfico e, posteriormente, foi realizada a tomografia e estereolitografia para o planejamento da cirurgia para correção do desvio angular, utilizando a metodologia de correção para desvio angular, denominada de técnica do centro de rotação da angulação (CORA) fechada, removendo uma cunha do osso para a correção da deformidade. A cirurgia foi bem-sucedida, apresentando bons resultados conformacionais, evoluindo sem complicações.(AU)

Tibial pes varus is an angular deviation resulting from the early partial closure of the physeal line of bone growth, leading to joint misalignment with abnormal support and overload, secondarily causing osteoarthritis, claudication, patellar dislocation, pain, among other joint problems. In this report, a female Dachshund canine was diagnosed with this condition bilaterally in the tibias. It was observed a deviation of both hind limbs at 6 months of age. Confirmation of the varus deformity was made through radiographic examination, and later computed tomography and stereolithography were performed to plan the surgery to correct bilateral angular deviation of the tibia, using the angular deviation technique (CORA) closed, removing a wedge from the bone to correct the deviation angular. The surgery was successful, and the angular deviation was correctly corrected, presenting good results to the animal, without complications.(AU)

Surgical correction of metatarsal angular deviation in a Thoroughbred filly using wedge metatarsal ostectomy: a case report / Correção cirúrgica de desvio angular metatársico em uma potra Puro-Sangue utilizando ostectomia em cunha: um relato de caso

This study describes a corrective procedure for a metatarsal angular malformation using wedge ostectomy in a 41-day-old Thoroughbred filly. A 41.6 °angular malformation of the metatarsus was corrected with wedge ostectomy of the left hindlimb in association with a type II external fixator and methyl methacrylate resin. The animal was subjected to the surgical procedure under general anesthesia. The filly was placed in dorsal recumbency with the left hind limb free for manipulation. A bone saw was used for the wedge ostectomy, while the bars for external fixation were placed using a drill. A Kirschner pin and acrylic resin were then applied. Radiographic images obtained immediately after surgery confirmed a total malformation reduction of 32.6 (from 41.6° to 9°). With medication and a Robert Jones bandage, intensive postoperative care was instituted to ensure that the animal adapted properly to the linear external fixator without overloading the pins and connection bars. No postoperative complications were observed. On the day after surgery, the filly was standing and walking with no signs of pain. After 180 days, total osseous calcification was achieved, and the implants were removed during the second surgery. The filly demonstrated adequate locomotion, performed all the movements, and ran without any difficulty in the paddock. The remaining discrete angular deviations were partially corrected using hoof trimming.

O objetivo desse estudo é descrever o procedimento de correção da malformação de desvio angular metatársico, utilizando ostectomia em cunha, em uma potra puro-sangue de 41 dias de idade. Uma malformação metatársica angular de 41.6º foi corrigida com a técnica de ostectomia em cunha, em associação com fixador externo tipo II e resina de metilmetacrilato, no membro pélvico esquerdo. O animal foi submetido à cirurgia sob protocolo de anestesia geral. A potra foi posicionada em decúbito dorsal, com o membro pélvico esquerdo livre para manipulação. Para a realização da ostectomia em cunha, foi utilizada uma serra óssea. Para a instalação das barras do fixador externo, uma furadeira foi utilizada e, para fixá-los, pinos de Kirschner e resina acrílica foram aplicados. Logo após a cirurgia, imagens radiográficas foram obtidas para confirmar a redução total de 32,6º (de 41,6º para 9º) de angulação. Para garantir que o animal se adaptasse ao fixador externo linear e não sobrecarregasse os pinos e barras, foram instituídos cuidados pós-operatórios intensos, com medicações e bandagem de Robert Jones. Não houve complicações no pós-operatório. No dia seguinte à cirurgia, a potra estava em pé, caminhando e sem sinais de dor. Após 180 dias, alcançou total calcificação óssea e os implantes puderam ser removidos em um segundo tempo cirúrgico. A potra demonstrou locomoção adequada, realizando todos os movimentos normais e pôde correr pelo pasto sem dificuldades. Um discreto desvio angular remanescente foi parcialmente corrigido por casqueamento.

Relato de caso: tratamento de ferida perfurante no dígito de equino / Case report: treatment of a perforating wound in the equine digit / Caso clínico: tratamiento de una herida perforante en el dedo equino

Apesar dos avanços na medicina equina, certas condições de claudicação ainda representam um desafio significativo para os clínicos veterinários, especialmente quando se trata de afecções distais, como feridas perfurantes no casco do equino. Essas lesões podem afetar estruturas vitais, incluindo a articulação interfalângica distal, o osso navicular, a bolsa do osso navicular, o tendão flexor digital profundo, a bainha sinovial e a terceira falange. O presente estudo tem como objetivo esclarecer que um diagnóstico mais rápido e preciso das estruturas afetadas e do grau de lesões resultantes leva a um tratamento mais eficaz. Além disso, foi demonstrado que o tratamento convencional com antibióticos e anti-inflamatórios não esteroides sistêmicos -AINEs,em combinação com terapias alternativas, como campo magnético pulsado, laser classe III e Ozonioterapia, apresentou um efeito sinérgico com resultados excelentes.(AU)

Despite advances in equine medicine, certain claudication conditions still pose a significant challenge to veterinary clinicians, especially when it comes to distal affections such as puncture wounds on the equine hoof. These injuries can affect vital structures, including the distal interphalangeal joint, navicular bone, navicular bone pouch, deep digital flexor tendon, synovial sheath, and third phalanx. The present study aims to clarify that a more rapid and accurate diagnosis of the affected structures and the resulting degree of injury leads to more effective treatment. Furthermore, it was shown that conventional treatment with antibiotics and systemic non-steroidal anti-inflammatory drugs -NSAIDs, in combination with alternative therapies, such as pulsed magnetic field, class III laser and ozone therapy, presented a synergistic effect with excellent results.(AU)

Occurrence of clinical laminitis after adaptation to confinement: effects on morphology, density, and mineral composition of the hoof of Nellore cattle after finishing / Ocorrência de laminite clínica após adaptação ao confinamento: efeitos na morfologia, densidade e composição mineral do casco de bovinos Nelore após terminação

Laminitis is a disease that affects the dermis and epidermis of the bovine hoof, generating changes in the hoof capsule. This study evaluated the effects of clinical laminitis diagnosed after the adaptation phase to confinement on the morphology, density, and mineral composition of the hoof of Nellore cattle after finishing. The animals were separated in the first weeks of confinement into a sick group (SG), with clinical laminitis, and a healthy group (HG). SG animals had higher heel length, dorsal wall length, toe height, and diagonal hoof length (p<0.05) than healthy animals. The dermal laminae had similar measurements for thickness, length, and spacing between them between SG and HG. Animals with laminitis showed congestion, hemorrhage, and basement membrane irregularities on histology. Computed microtomography (µCT) revealed that the hoof density of sick animals is lower than healthy ones. According to the mineral composition by energy-dispersive X-ray fluorescence (ED-XRF) spectrometry, the hooves of animals with laminitis (SG) and healthy ones (HG) were not biochemically different. Therefore, the occurrence of clinical laminitis in Nellore cattle in the first weeks of confinement causes an increase in the morphometric parameters of the hoof capsule and a reduction in the density of the abaxial hoof wall evaluated after the finishing period. This disease does not promote changes in the histomorphometric parameters of the dermal laminae and the percentage of minerals in the abaxial hoof wall.

A laminite é uma doença que afeta a derme e epiderme do casco de bovinos gerando alterações no estojo córneo. O estudo avaliou os efeitos da laminite clínica diagnosticada após a fase de adaptação ao confinamento na morfologia, densidade e composição mineral do casco de bovinos da raça Nelore após terminação. Nas primeiras semanas de confinamento, os animais foram separados em um grupo doente (GD) com laminite clínica e em um grupo saudável (GS). Os animais do GD apresentaram maior comprimento de talão, comprimento da parede dorsal, altura da pinça e comprimento diagonal do casco (p<0,05) do que os saudáveis. As lâminas dérmicas tiveram medidas semelhantes para espessura, comprimento e espaçamento entre elas entre GD e GS. Animais doentes apresentaram congestão, hemorragia e irregularidades da membrana basal na histologia. A microtomografia computadorizada (µCT) revelou que a densidade do casco de animais doentes é menor do que o saudável. Para a composição mineral por meio da espectrometria de fluorescência de raio-X por dispersão de energia (ED-XRF), o casco dos animais doentes (GD) e dos saudáveis (GS), não se mostraram diferentes bioquimicamente. Conclui-se que a ocorrência de laminite clínica em bovinos da raça Nelore nas primeiras semanas de confinamento ocasiona aumento de parâmetros morfométricos do estojo córneo e redução da densidade da parede abaxial do casco, avaliados após o período de terminação. Essa enfermidade não promove modificações nos parâmetros histomorfométricos das lâminas dérmicas e na porcentagem de minerais da parede abaxial do casco.

Utilização de filamentos de ouro em pontos de acupuntura em lobo-guará (Chrysocyon brachyurus) com espondilose / Use of gold filaments in acupuncture points in maned wolf (Chrysocyon brachyurus) with spondylosis / Implantación de filamentos de oro en puntos de acupuntura en aguará guazú (Chrysocyon brachyurus) com espondilosis

Um lobo-guará (Chrysocyon brachyurus) macho com 15 anos de idade apresentou dificuldade ao se levantar e deitar, relutância ao caminhar e aspecto arqueado da coluna vertebral. Após contenção química, o paciente foi examinado e submetido a exames radiográficos e colheita de material biológico para análises laboratoriais. Os resultados dos exames apontaram um animal saudável, porém visualizaram-se espondiloses em coluna vertebral na região cervical e torácica. Foi iniciado protocolo para controle de dor, inflamação e uso de regenerador articular, a fim de estabilizar o quadro do paciente. Novo manejo foi agendado para implante de filamentos de ouro em pontos de acupuntura. Após essa terapia, o paciente foi acompanhado pela equipe veterinária, e alguns dias após o tratamento houve melhora do quadro clínico o animal deixou de apresentar dificuldade para caminhar, deitar, levantar e ficar em estação. O paciente retornou ao recinto, dividindo o local com a fêmea, e até o momento está assintomático.(AU)

A 15-year-old male maned wolf (Chrysocyon brachyurus) showed difficulty getting up and lying down, reluctance to walk and an arched aspect of the spine. After chemical containment, the patient underwent physical examination and was submitted to radiographic examens and collection of biological material for laboratory analysis. The test results indicated a healthy animal, but spondylosis was seen in the cervical and thoracic spine. A protocol was started to pain control, inflammation, and use of condroprotective to stabilize the patient's condition. A new management was scheduled for the implantation of gold filaments in acupuncture points. After this therapy, the patient was followed up by the veterinary team, and days after the treatment, there was an improvement in the clinical condition- the animal had no more difficulty walking, lying down, getting up and standing still. The patient returned to the enclosure, sharing the place with the female, and so far, the clinical signs presented are absent and/or reduced.(AU)

Un aguará guazú (Chrysocyon brachyurus) macho de 15 años mostró dificultad para levantarse y acostarse, renuencia a caminar y un aspecto arqueado de la columna vertebral. Después de la contención química, el paciente fue examinado y sometido a exámenes radiográficos y recolección de material biológico para análisis de laboratorio. Los resultados de la prueba indicaron un animal sano, pero se observó espondilosis en la columna cervical y torácica. Se inició protocolo de control del dolor, inflamación y uso de protectores articulares, con el fin de estabilizar el estado del paciente. Con el objetivo de brindar una mejor calidad de vida, ya que se trata de un animal salvaje, incapaz de realizar ordinariamente terapias invasivas, se implantaron filamentos de oro en puntos de acupuntura. Posteriormente a esta terapia, el paciente fue acompañado por el equipo veterinario, y dias después del tratamiento hubo una mejoría en el estado clínico - el animal no tuvo dificultad para caminar, acostarse, levantarse y estar de pie. El paciente regresó al recinto, compartiendo el lugar con una hembra, y hasta el momento los signos clínicos anteriormente presentados están ausentes y/o reducidos.(AU)

Laminite crônica em equino - tratamento com uso de ferradura com travessa horizontal e massa epóxi / Chronic laminitis in a horse - treatment with use of horseshoe with horizontal cross and epoxy putty

Background: Laminitis is characterized by an inflammation of the laminar structures of the hoof, which results in lamellar degradation of the suspensory apparatus of the distal phalanx. Despite being a common disease in the equine clinic, it is a medical emergency, which can lead the affected animals not return to sports activities. Due to the severity of laminitis and the poor prognosis, the objective was to report the case of a horse with chronic laminitis with sole perforation in all limbs treated with therapeutic shoeing using a type of horseshoe that has a horizontal crossbar and is filled with mass. Fast-drying epoxy, which has its use little described in the literature Case: A 4-year-old Crioula horse, weighing 325 kg, used in long noose competitions, was referred to the Veterinary Hospital of UFPR with chronic laminitis. The animal had reluctance to move, walk on a trestle position, grade V lameness and phalanx rotation of all limbs. The treatment of laminitis was carried out in the field, for two months, which consisted of trimming and shoeing with a horseshoe in the shape of a heart, and due to the failure of the treatment instituted, the patient presented clinical worsening. The treatment in the HV consisted of cleaning the perforated region of the sole with hydrogen peroxide and 10% iodine and dressing with cotton boots with EVA rubber on the sole to provide comfort. Corrective trimming was performed in order to remove excess forceps, lower the heel, and align the distal phalanx with the hoof wall, using a rasp. Orthopedic shoeing was performed with a normal horseshoe with a horizontal crossbar in the central region. The sole was filled with a quick-drying epoxy putty (Poxilina®), with the aim of preventing sole movement, blocking the rotation of the phalanges and improving the concavity of the hoof. Discussion: In chronic laminitis, the signs observed are claudication and deformation of the hoof, flat sole, enlargement of the white line, uneven growth of the hoof wall, hemorrhage in the abaxial white line, cracks in the hoof wall, which are observed parallel to the coronary band, in addition to phalanx rotation; in this clinical case, all these signs were observed. The trimming of horses with laminitis consists of removing the heels and decreasing the dorsal wall of the hoof, in this case, the trimming performed improved the clinical improvement of the animal five days after the procedure. The horseshoe used in the treatment of this animal has the objective of creating a weight-bearing surface on the middle of the sole, close to the tip of the frog, in this way the weight is not on the supporting edge of the clamp and, in this way, it reduces the pressure. over the most affected area. Despite the scarcity of reports on the use of this type of horseshoe, in this case it played a fundamental role in the treatment of laminitis. In this way, it is an alternative that must be taken into account when choosing the treatment, in view of its effectiveness and lower cost when compared to other methods. This case demonstrates the severity of laminitis in all limbs, especially as it presents a perforation of the sole. It is important to highlight that trimming and shoeing performed at the recommended interval (30-45 days) contributes a lot to the success of the treatment and the return of the animal to sports practice. The horseshoe with a horizontal crossbar was effective in the treatment of chronic laminitis of the forelimbs and pelvic limbs in the reported animal, with progressive improvement of the patient who returned to normal daily activities, without the presence of signs of pain or signs of laminitis after treatment.

Amputation of the front medial digit of a Holstein cow - successful parturition and milk production

Background: Diseases of the bovine digit and hoof remain major problems in dairy farming and the beef cow industry. Severe claudication accompanying swelling and pain at the lesion is often observed in deep digital sepsis, septic arthritis, severe sole ulcers, and chronic interdigital phlegmon. In addition, digital amputation is often performed in cases of white line disease or severe trauma, such as bone fractures. There are few reports of amputation of the medial digit of the bovine front hoof. In this case, amputation of the medial digit of the front leg of a pregnant cow was performed; its hospitalization and return to productivity is reported. Case: The bovine was a 9-year-old Holstein cow in the 6th month of pregnancy, weighing 671 kg. Upon admission, the cow could not bear weight on its right front leg, and swelling and a purulent discharge were observed in the coronary area of the medial digit. X-ray examination results indicated a periosteal reaction centered on the 3rd phalanx of the medial digit of its right front leg hoof and slight periosteal reactions at the adaxial sides of the middle and proximal phalanges, strongly suggestive of septic arthritis caused by infection. According to the X-ray examination results, no abnormalities of the lateral digit of the front right hoof were observed; thus, it was estimated that the post-amputation hoof would be able to bear weight. Therefore, a decision was made to perform immediate amputation of the medial digit of the right front leg hoof to reduce pain for improved delivery of the offspring and improved milk production during the lactation period, rather than allowing the lesion progress until the dry period or the expected date of delivery. According to the X-ray examination results, amputation of the 1st phalanx alone was expected to suffice for removal of the cause of the pain; thus, a decision was made to perform amputation at the edge adjacent to the 2nd phalanx. The right front medial digit was prepared for aseptic surgery, and infiltration anesthesia was performed. An incision was made with a surgical knife at the interdigit of the right front limb. A wire saw was inserted into the site to cut the 2nd phalanx in the anti-axial direction down to the skin to resect the lesion. White viscous pus was discharged at the resection site; therefore, the wound was lavaged with tap water and packed with povidone iodine-impregnated gauze. The wound was also covered with a diaper and dressed with non-elastic and elastic bandages. The dressing was changed daily to aid wound healing. No problems were observed in the standing-up motion or other relevant movements immediately after the surgery. Granulation tissue formed rapidly, approximately 2 weeks after the surgery, and the lesion dried gradually. Approximately one month after the surgery, the subject exhibited little difficulty in both standing up and walking. The subject successfully delivered its 7th offspring at the farm on postoperative day 93. Discussion: The animal of this study was a 9-year-old, pregnant cow, and although amputation of the front medial digit is a relatively rare procedure, the cow was able to deliver and return to production, owing to sufficient postoperative treatment and care. The case also demonstrated the advantage of X-ray examination in bovine hoof diseases for accurate diagnosis, precise operation, and prognostic assessment.

Occurrence of foot diseases in cattle attended at the Clínica de Bovinos de Garanhuns: Epidemiological, clinical, therapeutic and economic aspects / Ocorrência de afecções podais em bovinos atendidos pela Clínica de Bovinos de Garanhuns: aspectos epidemiológicos, clínicos, terapêuticos e econômicos

The objective was to study the occurrence of foot disorders in cattle treated at the Clínica de Bovinos de Garanhuns, campus of the Universidade Federal Rural de Pernambuco from 1999 to 2021. A retrospective study of the medical records was carried out, with a total of 334 cases, in which 613 lesions were diagnosed. A frequency distribution, with simple mean and standard deviation was performed to evaluate the data. Interdigital dermatitis was more frequent in 12.4% (76/613), double sole in 9.79% (60/613), chronic laminitis in 8.81% (54/613), sole ulcer in 7.83% (48 /613), and interdigital hyperplasia in 7.24% (45/613). Laminitis and its consequences accounted for 45% of the total injuries identified, followed by 36% of injuries of secondary or uncertain cause, and 19% from infectious diseases. The distribution of lesions between the limbs was 68% in the pelvic and 32% in the thoracic limbs. Females, raised in a semi-intensive system, Holstein, with a body score of III, and large size were more affected. Lameness was present in 78% (260/334), while 10% (33/334) did not present lameness. The case fatality and recovery rates were 9% (31/334) and 73% (243/334), respectively. In total, 51% of cases occurred in the rainy season and 49% in the dry season. The main cities of origin were Bom Conselho 22.75% (76/334), Garanhuns 18.86% (63/334), and Brejão 12.57% (42/334). The estimated cost of treatment was US$ 150.13/case. Diseases are probably directly linked to management failure on the property due to the nature of the diagnosed diseases, in addition to the significant cost of the treatment of these animals, with the need for prophylactic measures in order to avoid the economic losses associated with foot diseases.

Objetivou-se estudar a ocorrência das afecções podais em bovinos atendidos na Clínica de Bovinos de Garanhuns, Campus da Universidade Federal Rural de Pernambuco, no intervalo de 1999 a 2021. Realizou-se estudo retrospectivo dos prontuários, com total 334 casos, dos quais foram diagnosticadas 613 lesões digitais. Foi realizada a distribuição de frequência, média simples e desvio padrão para avaliação dos dados. A dermatite interdigital foi a mais frequente, sendo observada em 12,4% (76/613) dos casos, seguida por sola dupla 9,79% (60/613), laminite crônica 8,81% (54/613), úlcera de sola 7,83% (48/613) e a hiperplasia interdigital 7,24% (45/613). A laminite e suas consequências representaram 45% do total de lesões identificadas, acompanhadas por 36% das injúrias de causa secundárias ou incertas e de doenças infecciosas com 19%. A distribuição das lesões entre os membros foi de 68% nos pélvicos e 32% nos torácicos. As fêmeas criadas em sistema semi-intensivo, holandesas, com escore corporal III e porte grande eram mais acometidas. A claudicação estava presente em 78% dos animais, enquanto 10% não claudicavam. As taxas de letalidade e recuperação foram de 9% (31/334) e 73 % (243/334), respectivamente. No período chuvoso foram 51% dos casos e 49% na época seca. Os principais municípios de origem foram Bom Conselho 22,75% (76/334), Garanhuns 18, 86% (63/334) e Brejão 12,57% (42/334). O custo estimado com tratamento foi de US$ 150,13/caso. Provavelmente falhas de manejo nas propriedades foram importantes fatores de risco para as doenças. Sugere-se a implementação de medidas profiláticas para evitar as perdas econômicas associadas às enfermidades podais.

Characterization and frequency of foot injuries and foot-related lameness in a sheep herd with prophylactic measures for foot-related diseases / Caracterização e frequência de lesões podais e da claudicação em rebanho ovino com medidas profiláticas de doenças podais

Foot lesions in sheep herds are responsible for great economic losses, because pain during locomotion interferes with feeding and behavior, leading productivity losses. The objective of this work was to describe the main foot disease found in sheep herd that uses prophylactic measures against foot diseases. A total of 346 ewes of different ages, with or without lameness, were assessed for the presence of foot lesions in all limbs, digits and adjacent structures. Among all the 2768 digits evaluated, 103 (29.76%) had lesions, representing 1.04 lesion per animal. 41.75% (43/103) had only one lesion, 39.81% (41/103) had two lesions, 16 (15.53%) had three lesions, and only 2.91% (3/103) had four or more lesions. Hind limbs were the most affected and the most frequent diseases were white line disease (40.05%), interdigital dermatitis (33.70%) and footrot (12.15%). It was concluded that foot disease in sheep is frequent and constitute a health problem for herds, even on farms that use strategies to prevent it. Therefore, it is essential to classify the lesions, as well as the adoption of effective prophylactic and therapeutic measures.

Lesões podais em ovinos são responsáveis por grandes perdas econômicas, pois a dor durante a locomoção interfere na alimentação e no comportamento, levando à perda de produtividade. O objetivo deste trabalho foi descrever as principais doenças podais encontradas em rebanho ovino, que utiliza medidas profiláticas contra as doenças podais. Foram examinadas 346 ovelhas quanto à presença de lesões podais em todos os membros, dígitos e estruturas adjacentes. Entre os 2.768 dígitos avaliados, 103 (29,76%) apresentavam lesões, representando 1,04 lesões por animal. 41,75% (43/103) apresentavam apenas uma lesão, 39,81% (41/103) tinham duas lesões, 16 (15,53%) tinham três lesões, e apenas três animais apresentavam quatro ou mais lesões. Os membros posteriores foram os mais afetados e as doenças mais frequentes foram a doença da linha branca (40,05%), dermatite interdigital (33,70%) e footrot (12,15%). Pode-se concluir que as lesões podais em ovinos são frequentes e constituem um problema sanitário para os rebanhos, mesmo em propriedade que realiza medidas profiláticas. Portanto, é fundamental classificar as lesões, assim como adotar as medidas profiláticas e terapêuticas eficazes.

Metabolic imbalances, hoof injuries, and metabolic profile of high-producing Holstein × Gir cowsshowing lameness / Desequilíbrios metabólicos, lesões nos cascos e perfil metabólico de vacas Holandesa × Gir de alta produção apresentando claudicação

This study attempted to determine the associations between metabolic imbalances and lameness or hoof injuries in high-producing Holstein × Gir cows, and to determine whether the metabolic profile affects the occurrence of lameness. Eighty cows were followed from -60 to 60 days relative to calving and hoof injuries were reported on days -60, 7 and 60. Locomotion score (LS), body condition score (BCS), the concentrations of non-esterified fatty acids, ß-hydroxybutyrate, glucose, cholesterol, albumin, total protein, blood urea nitrogen (BUN), calcium, phosphorus, and magnesium, and the activity of aspartate aminotransferase were determined at days -42, -21, -7, 0, 7, 21 and 42. The McNemar and Chi-square tests were used to compare frequencies of lameness and hoof injuries over time and to verify the associations between lameness, BCS, hoof injuries, and metabolic disorders. Two-way repeated measures ANOVA was used considering groups (non-lame × lame cows) and variations of BCS and metabolites over time. Lameness and hoof injuries increased between days -60 (20% and 66.3%) and 60 (44.7% and 98.6%). Excessive postpartum loss of BCS (P=0.017) and subclinical hypocalcemia (P=0.012) were associated with lameness on day 60. In general, the metabolic profile did not differ between lame and non-lame cows but cholesterol, albumin, BUN and magnesium concentrations were higher in non-lame cows. The postpartum decrease in BCS can affect the occurrence of lameness, and the metabolic profile of lame cows shows little difference from that of non-lame cows.

Este estudo objetivou verificar as associações entre desequilíbrios metabólicos e claudicação ou lesões nos cascos em vacas mestiças Holandesa × Gir de alta produção e determinar se o perfil metabólico afeta a ocorrência de claudicação. Oitenta vacas foram acompanhadas de -60 a 60 dias em relação ao parto e as lesões nos cascos foram avaliadas nos dias -60, 7 e 60. O escore de locomoção (EL), o escore de condição corporal (ECC), as concentrações de ácidos graxos não esterificados, ß-hidroxibutirato, glicose, colesterol, albumina, proteína total, nitrogênio ureico no sangue (BUN), cálcio, fósforo e magnésio e a atividade da aspartato aminotransferase foram determinados nos dias -42, -21, -7, 0, 7, 21 e 42. Os testes de McNemar e de Qui-quadrado foram empregados para comparar as frequências de claudicação e de lesões nos cascos ao longo do tempo e para verificar as associações entre claudicação, ECC, lesões nos cascos e distúrbios metabólicos. A análise de variâncias de medidas repetidas bifatorial foi usada considerando-se grupos (vacas com claudicação × vacas sem claudicação) e variações de BCS e de metabólitos ao longo do tempo. A claudicação e as lesões nos cascos aumentaram entre os dias -60 (20% e 66,3%) e 60 (44,7% e 98,6%). A perda excessiva de ECC no pós-parto (P=0,017) e a hipocalcemia subclínica ao parto (P=0,012) foram associadas com claudicação no dia 60. Em geral, o perfil metabólico não diferiu entre vacas com e sem claudicação, mas as concentrações de colesterol, albumina, BUN e magnésio foram maiores em vacas sem claudicação. A redução do ECC no periodo pós-parto pode afetar a ocorrência de claudicação, e o perfil metabólico das vacas claudicantes apresenta pouca diferença em relação ao das vacas não claudicantes.

Use of aerobic treadmill exercises on nerve regeneration after sciatic nerve injury in spontaneously hypertensive rats

Purpose: Various postoperative protocols have been proposed to improve outcomes and accelerate nerve regeneration. Recently, the use of physical exercise in a post-surgical neurorraphy procedure has shown good results when started early. We experimentally investigated the hypothesis that post-operative exercise speeds up results and improves clinical and morphologic parameters. Methods: Isogenic rats were randomly divided into four groups: 1 SHAM; 2 SHAM submitted to the exercise protocol (EP); 3 Grafting of the sciatic nerve; and 4 Grafting of the sciatic nerve associated with the EP. The EP was based on aerobic activities with a treadmill, with a progressive increase in time and intensity during 6 weeks. The results were evaluated by the sciatic functional index (SFI), morphometric and morphologic analysis of nerve distal to the lesion, and the number of spinal cord motor neurons, positive to the marker Fluoro-Gold (FG), captured retrogradely through neurorraphy. Results: Functional analysis (SFI) did not show a statistical difference between the group grafted with (­50.94) and without exercise (-65.79) after 90 days. The motoneurons count (Spinal cord histology) also showed no diference between these groups (834.5 × 833 respectively). Although functionally there is no difference between these groups, morphometric study showed a greater density (53.62) and larger fibers (7.762) in GRAFT group. When comparing both operated groups with both SHAM groups, all values were much lower. Conclusions: The experimental model that this aerobic treadmill exercises protocol did not modify nerve regeneration after sciatic nerve injury and repair with nerve graft.

Eficácia in sílico do florfenicol no tratamento de pododermatite infecciosa por Fusobacterium necrophorum em ovelhas / In sílico efficacy of florfenicol in the treatment of Fusobacterium necrophorum infectious pododermatitis in sheep

Objetivou-se comparar o efeito in silico do florfenicol nas doses de 20 e 30 mg/Kg em ovinos pelas vias intravenosa (IV) e intramuscular (IM), usando a modelagem PK/PD. Realizou-se uma simulação de Monte Carlo com base nos dados de concentração plasmática de um estudo publicado anteriormente. Calculou-se a área sob a curva (ASC) e as taxas de eficácia do florfenicol para os efeitos bacteriostático, bactericida e de erradicação bacteriológica. A dose de 20 mg/Kg IV demonstrou efeitos de erradicação de 100, 93 e 0% para CIM de 0,5, 1 e acima, respectivamente. O efeito bacteriostático foi de 99 e 90% para CIM de 4 e 2 µg/ml, enquanto o bactericida foi de 14% para CIM de 2 µg/ml. A dose de 30 mg/Kg IV apresentou 100% de erradicação para CIM de 1 µg/mL e 100% de efeito bactericida para CIM de 2 µg/mL. Há 100% de efeito bacteriostático em CIM de 4 µg/ml. As doses de 20 e 30 mg/Kg IM mostraram 100% de erradicação para CIM até 1 µg/mL e 0% para CIM maiores. O efeito bacteriostático foi mantido em 100% para uma CIM de 4 µg/mL em ambas as doses. Este estudo mostra o efeito de erradicação bacteriológica do florfenicol nas doses de 20 e 30 mg/Kg, IV e IM. Recomenda-se que seja feito um estudo de eficácia in vivo com a dose de 30mg/Kg IM em ovinos infectados por F. necrophorum com MIC superior a 2 µg/mL.

We aimed to compare the in silico effect of florfenicol at doses of 20 and 30 mg/Kg in sheep by intravenous (IV) and intramuscular (IM) routes, using PK/PD modeling. We performed a Monte Carlo simulation based on plasma concentration data from a previously published study. We calculated the area under the curve (AUC) and the efficacy rates of florfenicol to bacteriostatic, bactericidal, and bacteriological eradication effects. The dose of 20 mg/Kg IV demonstrated 100, 93, and 0% eradication effects for MICs of 0.5, 1, and above, respectively. The bacteriostatic effect was 99 and 90% for MIC of 4 and 2 µg/ml, while the bactericide was 14% for MIC of 2 µg/ml. The 30 mg/Kg IV dose showed 100% eradication for MIC of 1 µg/mL and 100% bactericidal effect for MIC of 2 µg/mL. There is a 100% of bacteriostatic effect at MIC of 4 µg/ml. Doses of 20 and 30 mg/Kg IM showed 100% eradication for MIC up to 1 µg/mL and 0% for MIC above. The bacteriostatic effect was maintained at 100% for a MIC of 4 µg/mL at both doses. This study shows the bacteriological eradication effect of florfenicol at doses of 20 and 30 mg/Kg, IV, and IM. Therefore, we recommend an in vivo efficacy study with a dose of 30mg/Kg IM in sheep infected with F. necrophorum with MIC greater than two µg/mL.

Plasma rico em plaquetas e células tronco no tratamento de desmopatia dos ligamentos colaterais distais em equino / Platelet-rich plasma and stem cells in the treatment of desmopathy of the distal collateral ligaments in equine

Os equinos são animais muito utilizados em eventos esportivos, sendo, desta forma, propensos a sofrer acidentes que podem levar a lesões articulares e ósseas. Na rotina clínica, artifícios como o uso de raio X e ultrassonografia são de grande importância para que o correto diagnóstico seja feito e a conduta clínica possa ser melhor planejada. Além disso, alguns biomateriais, como o plasma rico em plaquetas (PRP) e células-tronco mesenquimais (CTMs), têm se inserido nos protocolos terapêuticos, demonstrando grande efetividade no tratamento desse tipo de lesão, devido à grande quantidade de fatores de crescimento presentes em ambos os biomateriais. O PRP é um derivado sanguíneo, caracterizado pela alta concentração plaquetária. Foi produzido a partir de duas centrifugações, a primeira para separar o plasma das hemácias e a segunda para concentrar as plaquetas. As CTMs foram isoladas de tecido adiposo, cultivadas, transportadas e aplicadas de forma autóloga, assim como o PRP. No presente relato, um equino, fêmea, Brasileiro de Hipismo com 8 anos, foi diagnosticado com desmopatia nos ligamentos colaterais da articulação interfalângica distal e foi tratado com PRP e CTMs, de forma associada e sequencial. Foi encontrada uma melhora do quadro clínico, significativa, em comparação aos dados encontrados na literatura, demonstrando grande potencialidade do uso associado de PRP e CTMs no tratamento de lesões ligamentares.

Horses are animals widely used in sporting events and are therefore prone to accidents that can lead to joint and bone injuries. In the clinical routine, devices such as the use of X-ray and ultrasound are of great importance for the correct diagnosis to be made and the clinical conduct can be better planned. In addition, some biomaterials such as platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) have been included in the therapeutic protocols, demonstrating great effectiveness in the treatment of this type of injury due to the large amount of growth factors present in both biomaterials. PRP is a blood derivative, characterized by high platelet concentration. It is produced from two centrifugations, the first to separate plasma from red blood cells and the second to concentrate platelets. MSCs were isolated from adipose tissue, cultured, transported and applied autologously, as well as PRP. In the present report, an 8-year-old female Brazilian equestrian horse was diagnosed with desmopathy in the collateral ligaments of the distal interphalangeal joint and was treated with PRP and MSCs in an associated and sequential manner. A significant improvement in the clinical picture was found in comparison to the data found in the literature, demonstrating great potential of the associated use of PRP and MSCs in the treatment of ligament injuries.

Absorption and mobility of radio-labelled calcium in chili pepper plants and sweet cherry trees

Calcium (Ca) is often supplied to crop species to prevent the occurrence of Carelated disorders. Mechanisms of Ca absorption and transport are not fully understood and the effectiveness of root and/or foliar Ca fertilization may be variable. To characterize the rate of Ca absorption and transport, trials were developed with chili pepper and sweet cherry plants, using 45CaCl2 as a tracer. The Ca treatments supplied were: (1) No 45Ca (control); (2) 45Ca soil application; (3) 45Ca supply to basal leaves, and (4) 45Ca application to apical leaves. After two months, plants were harvested for biomass and Ca content determination. The recovery of 45Ca in different plant parts was measured with a liquid scintillation counter and leaf traits were observed by scanning electronic microscopy. In general, the highest 45Ca concentrations were recovered in treated organs, while root applications led to highest 45Ca translocation rates, which varied between chili pepper and cherry plants. For chili pepper, 45Ca applied to the soil was detected mainly in roots (44 %) followed by leaves (36.6 %) stems (17.4 %) and fruits (2 %). In sweet cherry trees, soilapplied 45Ca was principally recovered in roots (45.3 %), shoots (28.5 %), leaves (14.3 %) and trunks (11.9 %). The results provide evidence of increased absorption of rootapplied Ca, as well as different degrees of Ca mobility between species. Foliar application led to major Ca increases in treated leaves, with Ca transported to other plant organs after apical leaf Ca supply chiefly in cherry trees.(AU)

Avaliação hematológica e hepática de ovinos sob tratamento com torta de neem (Azadirachta indica) / Hematological and liver evaluation of sheep under treatment with neem pie (Azadirachta indica)

Devido aos altos índices de resistência dos parasitas aos diferentes princípios ativos comerciais, novas alternativas de controle vêm sendo estudadas, entre elas a fitoterapia. Essas medidas visam a busca de métodos auxiliares no controle das parasitoses, entretanto, muitos produtos estão disponíveis no mercado e não têm comprovação científica de sua eficácia ou de possíveis efeitos colaterais. O objetivo deste estudo foi avaliar os efeitos hematológicos e hepáticos após a administração de torta de Neem (Azadirachta indica) em ovinos. Foram testadas três dosagens da torta de Neem adicionada ao sal mineral (1, 2 e 4%), administradas por 126 dias para 32 ovinos da raça Lacaune, divididos em quatro grupos sendo três grupos para os diferentes tratamentos e um controle, o qual recebeu somente sal mineral. Amostras de sangue foram colhidas a cada 21 dias para realização do hemograma completo, dosagem de proteína plasmática total e fibrinogênio e avaliação da bioquímica clínica hepática. Nestas mesmas ocasiões, amostras de fezes foram coletadas para a quantificação de ovos por grama de fezes (OPG). Foram observadas diferenças estatísticas entre momentos e grupos para diversas variáveis, porém sem estarem relacionadas à administração de torta de Neem. Os resultados obtidos de hemograma completo, dosagem de proteína plasmática total, fibrinogênio e de bioquímica clínica hepática indica(AU)

Due to high levels of parasite resistance to different commercial active ingredients, new control alternatives are being studied, including the phytotherapy. These measures aim to search for auxiliary methods in the control of parasitic diseases. However, there are many products available in the market and there are no scientific proof of its efficacy. The objective of this study was to evaluate the hematological and hepatic effects following administration of Neem pie (Azadirachta indica) in sheep. Three concentrations of Neem cake was added to the mineral salt (1, 2 and 4 %) and administered during 126 days to 32 Lacaune breed sheeps, divided into four groups: three groups for different treatments and a and a control were tested, the ladder receiving only mineral salt. Blood samples were taken every 21 days to perform the complete blood count, serum total plasma protein and fibrinogen and liver biochemical evaluation. In those same times, fecal samples were collected for quantification of eggs per gram of feces (EPG). Statistical differences between times and groups for several variables were observed, but without being related to the administration of Neem pie. The results of complete blood count, measurement of total plasma protein, fibrinogen and hepatic clinical biochemistry indicated that administration of Neem pie at concentrations of 1, 2 and 4%, does not interfere in hematological values, or on the integrity and liver function Lacaune sheep breed.(AU)
