RESUMO
OBJECTIVE: The aim of this study was to perform gait analysis using a pressure-sensitive walkway in dogs submitted to high (total) or low amputation (partial) of one forelimb or hindlimb. STUDY DESIGN: A total of 39 dogs met the inclusion criteria. The reasons for the amputations were motor vehicle accidents in 38 dogs and possible limb malformation in 1 dog. The amputee dogs were divided into four groups: G1 (n = 10)-high forelimb; G2 (n = 10)-low forelimb; G3 (n = 9)-high hindlimb; and G4 (n = 10)-low hindlimb. For kinetic evaluation, the dogs were walked across a pressure-sensitive walkway. RESULTS: In dogs with forelimb amputation, the percentage of body weight (%BW) distribution on the contralateral forelimb was 50.7% in cases of high amputation and 55.5% in cases of low amputation, while the %BW distribution on the hindlimbs, mainly in the ipsilateral hindlimb, was 27.9% in cases of high amputation and 27.1% in cases of low amputation. In cases of high amputation of the hindlimb, the %BW distribution was 71.5% on the forelimbs and 29.7% on the contralateral hindlimb, while in cases of low amputation, the distribution was mainly for the contralateral hindlimb and ipsilateral forelimb. No statistical difference was noted between the amputation levels, except for the contralateral limb in cases of low and high amputation of the hindlimbs concerning the overload percentage and %BW distribution. CONCLUSION: The amputation level of one forelimb did not influence the %BW distribution; however, in the hindlimb, this was higher for the contralateral limb in dogs submitted to high amputation.

Descorna cirúrgica em bovinos é uma prática bastante realizada na medicina veterinária, com indicação principalmente para evitar acidentes com fraturas, trabalhadores e outros animais. O objetivo do presente relato seria ressaltar o uso de analgésicos e sedativos em bovinos submetidos a este procedimento cirúrgico, compartilhar técnica cirúrgica utilizada, informações de monitoramento de sinais vitais no trans cirúrgico e recomendações pré, trans e pós-cirúrgicas, assim como possíveis complicações. Foi atendido um bovino da raça Jersey, fêmea, 1 ano de idade, pesando cerca de 222kg, submetido a descorna bilateral devido ao comportamento agressivo. Contido em tronco de contenção e tranquilizado com acepromazina, recebeu meloxicam e associação de sulfa com trimetropim. Após tricotomia e antissepsia foi realizado bloqueio perineural do ramo cornual do nervo zigomático temporal e bloqueio infiltrativo ao contorno de cada corno com lidocaína sem vasoconstritor. Com os cornos insensíveis, se deu início ao procedimento de descorna cirúrgica pela associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber. Concluímos ser de extrema importância a execução da técnica cirúrgica por médico veterinário apto, realizando o procedimento de forma asséptica e com analgesia visando o bem estar do animal. No caso em questão, a associação das técnicas de serra de gigli com o alicate do tipo Dick Kaber foi parcialmente satisfatória, o animal apresentou boa margem de fechamento da sutura e sem deiscência dos pontos, porém houve dificuldades de retirada de margens ósseas pontiagudas após uso do alicate. A tranquilização associada ao bloqueio local foi efetiva para tal procedimento.(AU)
Surgical dehorning in cattle is widely performed practice in veterinary medicine, primarily indicated to prevent accidents involving workers, fights between animals, and skull fractures. This procedure involves the removal of the horns of the horns of cattle and should be performed using ethical methods by a qualified veterinarian. The objective of this case report is to highlight the use of analgesics and sedatives in cattle undergoing this surgical procedure, share the surgical technique employed, information on vital sign monitoring during the procedure, and pre-, intra-, and post-surgical recommendations, as well as potential complications. A Jersey cattle, female, 1 year old, weighing approximately 222kg, underwent bilateral dehorning due to aggressive behavior. Restrained in a cattle chute and tranquilized with acepromazine, she received meloxicam and a combination of sulfadiazine with trimethoprim. After trichotomy and antiseptic preparation, perineural blockade of cornual branch of the zygomatic temporal nerve was performed, follows by infiltrative blockade around each horn with lidocaine without vasoconstrictor. With the horns desensitized, the surgical dehorning procedure began using a combination of Gigli saw and Dick Kaber-type wire snare. In conclusion, it is of utmost importance for the surgical technique to be performed by a qualified veterinarian, ensuring aseptic procedure and correct analgesia for the well-being of the cattle. In this case, the combination of Gigli saw and Dick Kaber-type wire snare was partially satisfactory; the animal had a good suture closure margin and did not present suture dehiscence, but there were difficulties in we moving pointed bony margins after using the wire snare. Tranquilization combined with local blockade was effective for this procedure.(AU)
El descornado quirúrgico del ganado bovino es una práctica muy utilizada en medicina veterinaria, indicada principalmente para prevenir accidentes que involucren fracturas, trabajadores y otros animales. El objetivo de este informe sería resaltar el uso de analgésicos y sedantes en bovinos sometidos a este procedimiento quirúrgico, compartir la técnica quirúrgica utilizada, información sobre el monitoreo de signos vitales durante la cirugía y recomendaciones pre, trans y posquirúrgicas, así como posibles complicaciones. Se trata de una hembra bovina Jersey, de 1 año de edad, con un peso aproximado de 222 kg, siendo sometida a descornado bilateral por comportamiento agresivo. Se recibieron contenidos en un baúl de contención y tranquilizados con acepromacina, meloxicam y una combinación de sulfas y trimetopim. Mediante tricotomía y antisepsia se realizó bloqueo perineural de la rama cornual del nervio temporal cigomático y bloqueo infiltrativo en todo el contorno de cada miembro con lidocaína sin vasoconstrictor. Con cuerpos insensibles se inició el procedimiento de descornado quirúrgico, combinando técnicas de aserrado con alicates Dick Kaber. Concluimos que es de suma importancia realizar la técnica quirúrgica por un veterinario calificado, realizando el procedimiento de manera aséptica y con analgesia administrada para el bienestar del animal. En el caso que nos ocupa, la asociación de técnicas de la sierra con la pinza tipo Dick Kaber fue parcialmente satisfactoria, el animal presentó un buen margen de cierre de sutura y ninguna dehiscencia de los puntos, sin embargo, hubo dificultades para eliminar los márgenes óseos afilados después de usar alicates La tranquilidad asociada al bloqueo local fue eficaz para este procedimiento.(AU)

A 19-year-old male ostrich (Struthio camelus) was referred to a veterinary teaching hospital (São Paulo State University, Botucatu, Brazil) due to a 6-month history of recurrent prolapse of the phallus. On physical examination, 2 ulcerative wounds were present on the phallus, as well as caseous plaques and myiasis. Conservative treatment resulted in improvement but prolapse of the phallus remained. Thus, a decision was made to perform a partial phallectomy. The surgery was successful and no postoperative complications occurred. When the ostrich was reexamined 6 months postsurgery, the ostrich was alert, in good health, and the surgical site completely healed. The owner verbally reported no recurrence of the phallus prolapse 1 year after surgery.

OBJECTIVE: To describe the clinical characteristics, procedural techniques, complications, and outcomes of dogs and cats undergoing any of the following modified hemipelvectomy techniques: concurrent partial sacrectomy and/or partial vertebrectomy, osseous excision crossing midline, and reconstruction without the use of local musculature. ANIMALS: 23 client-owned animals (20 dogs and 3 cats) that underwent modified hemipelvectomy techniques. Animals that underwent traditional (nonmodified) hemipelvectomy techniques were excluded. PROCEDURES: The medical records of 3 academic institutions were reviewed, and data were recorded and analyzed. RESULTS: Modified hemipelvectomy was performed with partial sacrectomy and/or vertebrectomy in 11 dogs, excision crossing pelvic midline with concurrent limb amputation in 5 dogs and 2 cats, and closure without use of native muscle or mesh in 4 dogs and 1 cat. Surgery was performed for tumor excision in all cases. Excision was reported as complete in 16 of 23, incomplete in 6 of 23, and not recorded in 1 of 23 animals. All animals survived to discharge. Only animals undergoing partial sacrectomy/vertebrectomy (4/11) experienced postoperative mobility concerns. Major intra- or post-operative complications (grades 3 and 4) occurred in 2 dogs that underwent partial sacrectomy/vertebrectomy, and 1 of these animals experienced a complication that resulted in death. The median time to death or last follow-up was 251 days (range, 3 to 1,642). CLINICAL RELEVANCE: The modified hemipelvectomy techniques reported in this cohort were overall well tolerated with good functional outcomes. These findings support the use of these modified hemipelvectomy techniques in dogs and cats, and previous notions regarding tolerable hemipelvectomy procedures should be reconsidered. However, additional studies with larger numbers of patients undergoing modified hemipelvectomy techniques are needed to gain more information.

Background: The maned wolf (Chrysocyon brachyurus) is the largest canid in South America and the only representative of its genus. The scientific literature presents studies referring to the management and anaesthesia of the species but is scarce in case of emergency procedures, and to date, there are no reports of anaesthesia for emergency procedures in a neonatal maned wolf. Thus, this study aimed to report xenotransfusion and emergency anaesthesia for thoracic limb amputation in an approximately 8-days-old maned wolf pup. Case: A maned wolf pup, approximately 8-day-old, with a history of an accident with an agricultural machine, was referred to the Veterinary Hospital of the Federal University of Paraná - Palotina Sector (HVP - UFPR) with a grade III open fracture of left radius and ulna. At the physical evaluation, bullous rales were observed in the right caudal lobe on pulmonary auscultation, hypoglycemia and severe dehydration, the latter being determined by the occurrence of enophthalmos, increased capillary refill time and skin turgor (3 s). The hemogram revealed regenerative hypochromic macrocytic anaemia, thrombocytopenia and leukopenia, and the chest radiograph showed alveolar pattern opacification, associated with the presence of air bronchograms in the caudal lobes, more evident on the right side, suggestive of pulmonary contusion. Considering the laboratory alterations and the need for amputation of the thoracic limb, xenotransfusion was chosen before the anaesthetic procedure. The animal was pre-medicated with methadone 0.2 mg/kg and anaesthetic induction was performed with propofol titrated to effect, requiring 10 mg/kg. This was followed by endotracheal intubation and anaesthetic maintenance using the partial intravenous technique with an infusion of 5 µg/kg/h of remifentanil and Isoflurane vaporised through a non-rebreathing system in oxygen at 0.6. Anaesthetic monitoring included heart rate and electrocardiogram tracing, respiratory rate, oxyhemoglobin saturation, end-tidal partial pressure of carbon dioxide, systemic blood pressure by the oscillometric method, and oesophageal body temperature. Although the blood tests after the transfusion showed an increase in hematocrit, changes suggestive of a delayed hemolytic reaction because of the transfusion were also noticed. Discussion: Preanesthetic stabilisation is critical, as anaesthesia of unstable patients may result in a higher risk of anaesthetic complications. Critically ill patients may present systemic imbalances that can trigger pharmacokinetic and pharmacodynamic changes of anaesthetics and analgesics. Neonates have several marked physiological differences, since some organs are still immature, have a high body volume of water, and present a reduced amount of total fat and concentrations of circulating proteins, making it necessary to adjust protocols and doses used for these patients. Blood transfusion between the same species is always the best option, though xenotransfusion becomes an option when there is no homologous donor available. However, it can present a great risk to life, as there is a lack of studies regarding the blood typing of the species and blood compatibility tests. We concluded that there was an increase in hematocrit after 24 h of xenotransfusion and, even with signs of delayed hemolytic reaction observed in the blood test, the patient did not show specific clinical signs of transfusion reaction. The pup was sensitive to methadone but required a high dose of propofol for anaesthetic induction. The use of methadone as a pre-anaesthetic agent and the infusion of remifentanil provided adequate analgesia based on the parameters evaluated.

Background: The medical science of birds, with the exception of aviculture, has a very short history compared to other subdisciplines of veterinary medicine. With this in mind, the current work aims to report the case of a buff-necked ibis with an open fracture of the left humerus, presenting the surgical treatment and anesthetic protocol used, in order to contribute to the avian medical literature. Case: An adult buff-necked ibis (Theristicus caudatus) was referred to the University Veterinary Hospital with an open fracture of the left humeral shaft, 7 days after rescue. During the physical examination, a skin lesion was identified in the fracture area, with signs of low vascularization, devitalization, necrotic tissues, and purulent secretions being noted. On radiographic examination, the fracture was classified as comminuted, with exposure of the left humeral shaft. After evaluating the limb, it was decided to amputate the wing, and 24 h later, the patient was referred to the operating room after fasting for 4 h. As pre-anesthetic medication, ketamine (20 mg/kg) and midazolam (1 mg/kg) were administered, both intramuscularly. Orotracheal intubation was performed, after which the tracheal tube was connected to a Baraka-type gas-free system and the supply of isoflurane was started through a universal vaporizer, diluted in 100% oxygen. For transoperative analgesia, brachial plexus block was performed using 2% lidocaine (2 mg/kg). During the surgical procedure, an incision was made in the skin and subcutaneous tissue in the middle third of the left humerus, and detachment of the greater deltoid muscle was performed with a periosteal elevator, followed by excision of the tensor propatagialis. In the ventrodorsal region, circular ligation of the brachial vein, ulnar vein and artery, and median-ulnar nerve was carried out, and disarticulation of the scapulacoracoid-humeral region. Subsequently, abolition of dead space and a myorrhaphy were performed, followed by demorrhaphy. In the immediate post-operative period, morphine (5 mg/kg), meloxicam (0.1 mg/kg), and enrofloxacin (10 mg/kg) were administered intramuscularly. The patient was discharged from the hospital 6 h after the end of the surgical procedure. Discussion: Interest in the conservation of wild birds is one of the causes of the increased demand for anesthetic and surgical procedures in these species. However, it is a challenge for professionals in the field. The use of analgesics is recommended for reasons of well-being, but also because of the possibility of reducing the concentration of inhalational anesthetics in surgical procedures. Ketamine associated with midazolam promotes sufficient sedation and muscle relaxation in the patient, enabling safe preoperative management, in addition to reducing the amount of inhaled anesthetics used during the transoperative period. Isofluorane promotes safe general anesthesia for birds and has an advantage over injectable drugs, as it provides better dynamic control of anesthetic depth in these species. The brachial plexus block performed is a simple procedure that promotes quality anesthesia and analgesia in the perioperative period. The choice for amputation was due to the absence of musculature for closure, severe skin, muscle, and bone devitalization, and the infectious process in the region, factors that would prevent osteosynthesis. Although amputation through the bone is preferable, the disarticulation technique was used due to the absence of a healthy proximal humeral fragment. The patient's death can be explained by the poor nutritional status the bird was in, as it presented an open fracture with severe contamination, a concomitant injury that occurred during the possible trauma, and the excessive time between the day of the trauma and the day of medical attendance. However, the surgical and anesthetic procedures were adequate and satisfactory for the patient. The importance of identifying and treating diseases secondary to contaminated fractures in these species is emphasized.

Background: The Coragyps atratus flies long distances in search of food and has a marked behaviour of food competition. Since they are frequently found in areas of recent human occupation, they are subject to trauma, which may require surgical interventions. Locoregional blocks are used as part of a balanced-anaesthesia protocol and are currently being evaluated in birds, with brachial plexus block being the main technique described in the literature. However, to our knowledge, this is the first description of intravenous regional anaesthesia (Bier's block) in a vulture. Thus, we aim to report the use of Bier's block with 1% lidocaine, in a black-headed vulture submitted to digit amputation. Case: A black-headed vulture (Coragyps atratus), weighing 2 kg, was rescued and referred to the Veterinary Hospital due to its inability to fly. Physical examination revealed a swollen digit in the right pelvic limb. Radiographic examination confirmed the intermediate phalanx fracture of the 4th digit of the right pelvic limb with signs suggestive of advanced osteomyelitis. The animal was referred to surgery for amputation of the affected digit. Before surgery, water and food were withdrawn for 12 h. Pre-anaesthetic medication consisted of 1 mg/kg midazolam and 0.5 mg/kg morphine intramuscularly (IM). Anaesthetic induction was performed through face mask with isoflurane, followed by orotracheal intubation with a 3 mm-endotracheal tube. Anaesthesia was maintained with isoflurane through a non-rebreathing circuit in 100% oxygen. Using a multiparametric monitor, heart rate (HR), respiratory rate (RR), end-tidal CO2 (EtCO2 ), oxyhemoglobin saturation (SpO2 ), electrocardiography (ECG), systolic blood pressure (SBP) and core temperature (CT) were evaluated. Antisepsis of the right pelvic limb was performed and an elastic band was applied around the distal region of the affected tibia to serve as a tourniquet. A scalp vein set was used to access the lateral saphenous vein in the region distal to the tourniquet, and 5 mg/ kg lidocaine 1% was injected intravenously. The patient remained stable during the procedure, with no need for analgesic rescue. The tourniquet was gradually released 40 min past its application, being completely removed after 45 min of surgery. The anaesthetic supply was interrupted, with extubation after 4 min; the patient had satisfactory anaesthetic recovery. Discussion: The present report describes the success in using the technique of intravenous regional anaesthesia with 1% lidocaine for digit amputation performed on a specimen of black-headed vulture. The pre-anaesthetic medication provided analgesia, satisfactory sedation for venoclysis, and anaesthetic induction without complications. Anaesthetic induction and maintenance in birds are preferably performed with inhaled anaesthetics, thus the choice of mask induction. Despite the reduction in RR soon after induction, the patient remained on spontaneous ventilation. Bier's block using 5 mg/kg lidocaine showed to be an easy and safe technique in vultures, but doses up to 6 mg/kg lidocaine are not associated with adverse effects in birds. The intravenous regional anaesthesia technique described in this manuscript promoted adequate analgesia for the digit amputation procedure in black-headed vultures and allowed hemodynamic stability without significant anaesthetic complications. Thus, the present report points to the potential use of this locoregional block in other birds.

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.

Background: High voltage electric shock causes serious injury to the body, which can lead to a fatal condition. Sloths are commonly the target of this type of accident and factors such as the degree of tissue impairment and late medical care can contribute to the death of the animal or the indication of euthanasia. In this way, the present study aims to describe the treatment strategies in Choloepus didactylus victim of high voltage electrocution. Case: A female sloth weighing 6.15 kg was treated at the Wild Animals Sector of the Veterinary Hospital (HV-SAS) of the Federal University of Pará (UFPA) victim of high voltage electric shock with burn on the right side face, stomatitis, glossitis, lesions extensive and bullous lesions in the thoracic and pelvic limbs, in addition to an open fracture in the radioulnar joint of the left limb with signs of necrosis. After patient stabilization (fluid therapy, antibiotic therapy, pain control, cleaning and wound dressing), the patient was transfered to the impatient room. The main treatment strategies adopted were surgery, drug therapy, food and occupational therapy. The day after the patient's arrival, the amputation of the left thoracic limb was performed. On the third day of hospitalization, the right thoracic and pelvic limbs were also amputated, and on the tenth day, debridement of the right lateral face was performed. As for drug therapy, the following drugs were used postoperatively: ceftriaxone (40 mg/kg, BID, for 47 days), dexamethasone (0.5 mg/kg, BID, for 4 days), silymarin (15 mg/kg, BID, for 30 days), morphine (0.4 mg/kg, BID, for 14 days; 0.8 mg/kg, SID, for 22 days) and dressing wounds on the lateral face and surgical stumps with ointment of collagenase with chloramphenicol. In food management, the animal had good acceptance of a mixture of fruits, vegetables and animal protein in a pasty presentation. The treatment by occupational therapy included basic care such as exercising, sunbathing, and desensitizing the surgical stumps (massage therapy). In conclusion, after five months, the therapeutic protocol implemented resulted in the clinical improvement of the animal, as it allowed the complete healing of the lesions on the face and surgical stumps. In addition, the care taken with the surgical stumps allowed the animal to use them as support for its locomotion. Discussion: Amputation and debridement surgeries were effective in treating electrocuted patients and should be considered when tissue is compromised, which justifies the surgical protocol adopted in this study. They were based on reports in humans, since in wild animals, although many are victims of this type of trauma, little is known about the appropriate therapeutic approach for each species. Surgical interventions associated with the antibiotic ceftriaxone were efficient for controlling the infection, since this antibiotic has a broad spectrum of activity, being used mainly in skin and soft tissue and/or bone infections, which justified its use in that patient. As for nutritional therapy, supplementation with animal protein may have contributed to the clinical improvement of the animal, since they are excellent components for tissue recovery in patients who suffered losses from burns caused by electric shocks. Stump desensitization is indicated as a treatment for neuropathic pain in amputees, and in the present study, it was essential for the animal to use the limb for locomotion. The exercises in a grassy area associated with sunbathing added as a stimulus to the patient's movement.

O lipoma infiltrativo é uma neoplasia benigna rara que acomete os adipócitos. Apresenta etiologia desconhecida, sem raça predisponente. É altamente agressivo, não metastático e com índices de recidivas significativos. Um cão da raça Shih Tzu, macho, castrado e com 7 anos e 7 meses foi atendido na clínica veterinária da Universidade Salvador, com queixa de tumoração em membro torácico esquerdo, presente já há 5 anos. Exames de imagem, histopatológico e cirurgia confirmaram o diagnóstico de lipoma infiltrativo em tórax e membro torácico esquerdo. O tratamento preconizado foi amputação do membro devido a magnitude da infiltração. Para o pós-operatório foi realizada fisioterapia e acompanhamento. A recidiva, em região dorsal, se deu após 82 dias de cirurgia e novamente se optou pelo procedimento cirúrgico.

Surgical pathology of the musculoskeletal system, and in particular the diseases of the limb distal segment in pigs are quite common. Their significant spread leads to economic losses due to culling, compulsory slaughter, short-received pig production and pig crop. The purpose of this work was to reveal clinical and morphological features of limb distal segment diseases in pigs and to study the possibility of preserving their health and productivity. The conservative treatment of purulonecrotic lesions in the deep structures of the limb distal segment in pigs is not promising. It is shown that the best way to treat a given pathology is amputation of a sick limb. The technique of carrying out exarticulation of talus shin consists in separation of soft tissues, capsule and ligaments, ligation of vessels, formation of stump. The postoperative recovery period of the animal body is 25 days.(AU)
A patologia cirúrgica do sistema musculoesquelético e, em particular, as doenças do segmento distal dos membros em suínos são bastante comuns. A sua propagação significativa leva a perdas econômicas devido ao abate seletivo, abate obrigatório, produção de suínos pouco recebida e colheita de suínos. O objetivo deste trabalho foi revelar características clínicas e morfológicas das doenças do segmento distal de membros em suínos e estudar a possibilidade de preservar sua saúde e produtividade. O tratamento conservador das lesões purulonecróticas nas estruturas profundas do segmento distal do membro em porcos não é promissor. Fica estabelecido que a melhor forma de tratar uma determinada patologia é a amputação de um membro doente. A técnica de realizar a exarticulação da canela do talos consiste na separação dos tecidos moles, cápsula e ligamentos, ligadura dos vasos, formação do coto. O período de recuperação pós-operatória do corpo do animal é de 25 dias.(AU)

The purpose of this study was to evaluate infrared beak trimming versus hot-blade beak trimming on performance, organ and bone development of laying pullets, using 240 birds, at 0-16 weeks of age, from two strains (white layer - Hy-Line W36 and brown layer - Hy-Line Brown). Infrared debeaking was performed on the first day of life in the hatchery, whereas hot-blade beak trimming was performed at eight days of age. Zootechnical performance at 6, 9, 12 and 15 weeks of age was analyzed. At the end of the trial, one Bird per experimental unit was euthanized for liver, gizzard, proventriculus, heart and small intestine relative weight evaluation. Both tibiotarsus were collected to measure bone breaking resistance, bone mineral content and bone densitometry. There was higher body weight and feed intake in both bird strains submitted to infrared beak trimming. Additionally, hot-blade white layers presented lower body development and feed intake. The debeaking methods did not influence relative organ weights or tibiotarsus parameters evaluated. We conclude that the infrared beak trimming method promotes better pullet body development than the conventional hot-blade method, improving feed intake, without compromising organ and bone development, being a more adequate debeaking method to be used in layer production.(AU)
Para avaliar a debicagem infravermelha versus a debicagem pelo método da lâmina quente no desempenho, no desenvolvimento de órgãos e na qualidade óssea de poedeiras em recria, foram utilizadas 240 aves, entre zero e 16 semanas de idade, em duas linhagens (branca - Hy-Line W36 e vermelha - Hy-Line Brown). A debicagem por infravermelho foi realizada no primeiro dia de vida no incubatório, enquanto a debicagem com lâmina quente foi realizada aos oito dias de idade. Analisou-se o desempenho zootécnico na sexta, nona, 12ª e 15ª semanas de idade. No final do estudo, uma ave por unidade experimental foi eutanasiada para avaliação do peso relativo do fígado, da moela, do proventrículo, do coração e do intestino delgado, e ossos do tibiotarso foram coletados para avaliação da resistência à ruptura, do conteúdo mineral e da densitometria óssea. Houve maior peso corporal e consumo alimentar nas aves pertencentes às duas linhagens quando submetidas à debicagem por infravermelho, sem haver influência sobre o peso relativo dos órgãos e a qualidade óssea. Conclui-se que o método de debicagem por radiação infravermelha promove melhor desenvolvimento corporal das frangas em relação à debicagem por lâmina quente, melhorando consumo de ração, sem comprometer o desenvolvimento de órgãos e ossos, sendo mais adequada para utilização na avicultura de postura comercial.(AU)

Background: The maned wolf (Chrysocyon brachyurus) is the largest south american canid and deemed a near threatenedspecies according to the International Union for Conservation of Nature (IUCN). Typically found in Brazilian Cerrado, it isoften a victim of animal trappings and vehicular accidents, where it may get deeply injured or end up fractured, demandingorthopedic procedures. Even though maned wolves are similar to the domestic dog, little is described regarding generalanesthesia and its complications for major procedures in ill patients in the scientific database. This case report describesa successful blood transfusion and anesthetic management of a critically ill C. brachyurus.Case: An adult female maned wolf was rescued after getting steel-jaw trapped. After chemical restraint with intramuscular(IM) ketamine (12 mg/kg), midazolam (0.3 mg/kg) and methadone (0.3 mg/kg), physical examination showed exposedbones to the distal end of the right hind limb, pronounced dehydration and moderate anemia and thrombocytopenia according to blood count. Radiographic images enlightened multiple right tarsus fractures. As the wound was highly infected,which made the osteosynthesis procedure impossible, it was decided to amputate the limb on the following day. Subcutaneous (SC) lactated Ringers solution (250 mL), IM meloxicam (0.2 mg/kg) and IM enrofloxacin (10 mg/kg) were alsoadministered at first. On the following day, after aforementioned chemical immobilization, anesthesia was induced withdose-effect intravenous (IV) propofol (2 mg/kg) until orotracheal intubation was possible, and general anesthesia wasmaintained with isoflurane diluted in oxygen. Lumbosacral epidural anesthesia was obtained with 0.5% bupivacaine (0.25mL/kg) and morphine (0.1 mg/kg) to provide analgesia and to reduce inhalant agent...(AU)

Neuropathic pain occurs when there is a lesion or a dysfunction of the nervous system. Humans and veterinary patients may develop neuropathic pain, but in veterinary it is not often reported probably because of its mistaken diagnosis. A canine patient was admitted to the Veterinary Hospital of UNESP-Jaboticabal-SP, Brazil with a nodule on the left thoracic limb. The nodule was surgically removed, and histopathological analysis demonstrated the tumor was a soft tissue sarcoma (STS) and the margins were not clean. Based on the patient's health condition and the lack of suitable equipment, the next procedure was limb amputation. The patient received analgesic medication in the post-surgery period; nevertheless, clinical signs of neuropathic pain were present, such as compulsive licking and other behavioral disorders. Medications were administered for forty days, but clinical signs ceased only when replaced with a tryciclic antidepressant drug, Amitriptyline. Therapeutic management of the patient in this report can be considered effective, since five years after the end of the treatment there was no recurrence or presence of metastasis.(AU)
A dor neuropática ocorre quando há uma lesão ou disfunção do sistema nervoso. Tanto pacientes humanos quanto veterinários podem desenvolver a dor neuropática, mas na medicina veterinária ela é pouco relatada provavelmente por não ser corretamente diagnosticada. Um paciente canino foi atendido no Hospital Veterinário da Unesp-Jaboticabal, SP, Brasil, com um nódulo em membro torácico esquerdo. O nódulo foi removido cirurgicamente, e o exame histopatológico evidenciou a presença de sarcoma de tecidos moles (STM) e de margens comprometidas. Baseando-se nas condições de saúde do paciente e na ausência de equipamentos adequados, o próximo procedimento foi a amputação do membro. No pós-cirúrgico, o animal recebeu medicações analgésicas, todavia, mesmo assim, apresentava sinais de dor neuropática, como lambedura compulsiva e outros distúrbios comportamentais. O tratamento para dor aguda se estendeu por 40 dias; no entanto, os sinais clínicos cessaram apenas quando os analgésicos comuns foram substituídos por um medicamento antidepressivo tricíclico, a amitriptilina. O manejo terapêutico do paciente do presente relato pode ser considerado satisfatório, uma vez que, após cinco anos do término do tratamento, não houve recidiva nem presença de metástase.(AU)

Background: Locoregional anesthesia techniques enable the performance of procedures in the distal portion of the limbs,through the parenteral administration of local anesthetic nerve block. There are devices that can increase the effectivenessof these blocks by accurately locating the nerves. These devices include peripheral nerve stimulators, which enable anesthetic to be injected near the plexus, thus reducing the volume of anesthetic required and allowing for the specific blockadeof a nerve branch by desensitizing exclusively the area of interest. This paper describes the use of nerve stimulator in thebrachial plexus block (BPB) of a calf subjected to amputation of the left foreleg.Case: A newborn calf weighing 30 kg, with a history of injury to the left foreleg, was treated at the Veterinary Hospital ofthe Federal Rural University of the Semi-Arid Region. Clinical and X-ray examinations revealed a fracture in the medialportion of the metacarpus and radiographic alterations indicative of osteomyelitis, so amputation of the affected limb wasrecommended. Prior the beginning, during and after the surgical procedure, the animal was submitted to the evaluation ofits physiological parameters (heart and respiratory rate, capillary refill time, diastolic, systolic and mean blood pressure andrectal temperature). Because it is a newborn animal, it was decided not to pre-operatively fast. After applying preanestheticmedication (xylazine 0.01 mg/kg IV), anesthesia was induced with ketamine (2 mg/kg IV) and midazolam (0.3 mg/kg IV)and maintained with isoflurane. For the brachial plexus block, 0.4 mL/kg (1.5 mg/kg) of 0.375% bupivacaine was usedand aided by a peripheral nerve stimulator to generate 10 mA current, 1 HZ frequency and 100 μs pulse duration, coupledto a nerve stimulation needle, it was possible to observe flexion movements...(AU)

A 10-year-old female American Pit Bull dog was diagnosed with metastatic undifferentiated carcinoma of the scapula. Immunohistochemistry showed positive immunoexpression for cytokeratins (AE1/AE3, 34BE12, CK7) and vimentin, confirming squamous cell carcinoma. No evidence of nodules was found in the complete physical examination and imaging procedures conducted. The patient was diagnosed with carcinoma of unknown primary origin. Amputation and adjuvant chemotherapy with doxorubicin and piroxicam were performed, but the patient died of respiratory failure after 737 days of diagnosis. Necropsy confirmed undifferentiated carcinoma infiltrating the lungs and kidneys, and showing the same immunoexpression as the tumor in the scapula. Amputation associated with chemotherapy extended the overall survival time of this patient.

Background: Limb amputation may be a life-saving procedure for animals and minimally impact their comfort and qualityof life, as previously reported in pets. This procedure is an appropriate alternative to euthanasia when catastrophic injury toa limb prevents its successful restoration. In horses, limb amputation has been performed for the past 40 years. Althoughin the reviewed literature there are no scientific reports of limb amputation in donkeys. This paper aimed to report a successful forelimb amputation and long-term follow-up in a female donkey.Case: A 10-month-old and 95 kg female Nordestino donkey was evaluated for a wound with bone exposition on the leftforelimb. Physical examination revealed that the donkey was alert with moderate body condition score, tachycardia, tachypnea, and a medial wound revealing the necrotic aspect of the left radius. Radiographic examination presented Salter-Harristype 1 exposed radius fracture. Hematology revealed normocytic and normochromic anemia, and hyperfibrinogenemia.Due to the catastrophic injury and no forecast for building a prosthesis, the donkey underwent general anesthesia for leftforelimb amputation through the midhumerus diaphysis. A fish-mouth skin incision was performed on the midhumerus,the underlying musculature was dissected and the vessels ligated until the bone could be accessed. Then, a sterile sawwire was used to transect it, and bone edges were rounded. Muscle and fascia were harvested with the skin to provideadditional padding at the end of the stump. Postoperatively, the donkey was submitted to broad spectrum antibiotic, antiinflammatory and analgesic therapy, and tetanus prophylaxis. Preventative treatment for overload laminitis included frogsupport pads and resting leagues on all three legs. No short-term complications were observed and the donkey made a fullrecovery. Long-term complications included fistula formation on the stump, and distal interphalangeal joint...(AU)
