Fatal traumatic injuries in free-living wild Passeriformes and Psittaciformes birds in Central Brazil, 2006-2018 / Injúrias traumáticas fatais em aves Passeriformes e Psittaciformes no Brasil Central, 2006-2018

Traumatic injuries are a significant cause of death for birds worldwide, as they are at an increased risk of collisions and other injuries due to man-made environments. This study examined the frequency and morphological characteristics of fatal traumatic injuries in endemic and migratory Passeriformes and Psittaciformes from the Cerrado Biome, a biodiverse but threatened area in Brazil. Results showed that fatal traumatic injuries were found in 21.8% of birds (285/1305), mainly in spring and summer, during the birds' reproductive period. The yellow-chevroned parakeet (Brotogeris chiriri) and Passeriformes from the Thraupidae family were the most affected. Nearly 70% of the fatal injuries observed were to the thoracic, pelvic limbs, and skull, and types of fractures and affected bones were thoroughly evaluated. Blunt traumas were one of the most frequent causes of injuries. Injuries affecting the appendicular skeleton and head represented significant causes of traumatic death for Passeriformes and Psittaciformes. The frequency of these fatal injuries has been increasing in recent years, which may be related to the remarkable environmental changes in the Cerrado Biome and jeopardize the survival of many bird species.

As lesões traumáticas são uma causa significativa de morte nas aves em todo o mundo, pois apresentam um risco maior de colisões e outras lesões devido aos ambientes degradados e criados pelo homem. Este estudo examinou a frequência e as características morfológicas das lesões traumáticas fatais em Passeriformes e Psittaciformes endêmicos e migratórios do Bioma Cerrado, uma área com rica biodiversidade, mas ameaçada no Brasil. Os resultados demostraram que as lesões traumáticas fatais foram observadas em 21,8% das aves (285/1305), principalmente na primavera e verão, durante a época reprodutiva das aves. O periquito-do-encontro-amarelo (Brotogeris chiriri) e Passeriformes da família Thraupidae foram as aves mais frequentemente acometidas. Por volta de 70% das lesões fatais observadas foram nos membros torácicos e pélvicos, e crânio, e os tipos de fraturas e ossos afetados foram minuciosamente avaliados. Os traumas contudentes foram as principais causas das lesões. As injúrias que afetaram o esqueleto apendicular e a cabeça representaram as mais importantes causas de morte traumática para Passeriformes e Psittaciformes. A frequência dessas lesões fatais vem aumentando nos últimos anos, o que pode estar relacionado às mudanças ambientais marcantes no Bioma Cerrado e colocar em risco a sobrevivência de muitas espécies de aves.

Tratamento de tromboembolismo e preparo para implantação de prótese osteointegrada com oxigenioterapia hiperbárica em uma gata / Treatment of tromboembolism and preparation for an osseointegrated prothesis fixation with hyperbaric oxygen therapy in a kitten

Background: Ischemic neuromyopathy is the most common reason for amputation in cats. In veterinary medicine, the use of prosthetic limbs is not widespread; therefore, in most cases total limb amputation is indicated. However, hyperbaric oxygen therapy (HBOT) is an alternative with several benefits for the treatment of vascular disorders with reperfusion, ischemia, and infection. Therefore, this study aimed to report the positive effects of HBOT on the treatment of ischemic neuromyopathy secondary to arterial thromboembolism on the patient's clinical improvement, and on the preparation of the patient for insertion of an osseointegrated prosthesis. Case: A 6-month-old mixed-breed kitten returned for treatment after undergoing surgery seven days earlier for reduction of traumatic diaphragmatic hernia, during which it suffered a cardiorespiratory arrest. The patient presented with acute pelvic limb paralysis with 24-h evolution, absent femoral pulse, plantar cushions and dorsal part of the limbs cold and pale. After supportive therapy and diagnosis of aortic thromboembolism by arterial Doppler, the patient started adjunctive treatment with HBOT from the first day of hospitalization. Sessions took place in an exclusive hyperbaric chamber for animals and lasted 60 min at a pressure of 2.5 absolute atmospheres and 100% oxygen, initially every 12 h. However, during the first 5 days of hospitalization, the distal region of both pelvic limbs began to show tissue devitalization and edema, and hematologic parameters showed changes on the 7th day. The right pelvic limb (RPL) showed more involvement of superficial tissues, extending to the tarsometatarsal joint region. After 8 days of hospitalization, the devitalized tissue was debrided. The RPL had an extensive devitalized area with exposed bone in the phalanges and necrosis in the pads. The left pelvic limb (LPL) suffered minor complications, with involvement of the phalangeal region. After 12 days, with HBOT every 48 h, exuberant granulation tissue was observed. After 17 days, the patient was discharged, and HBOT sessions were performed weekly. Gangrene of the midfoot and lack of proprioception were observed in RPL, while LPL showed bone divulsion of the 1st, 3rd, and 4th phalanges. Because of the poor prognosis for limb viability, the RPL was partially amputated, and a self-threaded intraosseous prosthesis was inserted. Discussion: The cardiorespiratory arrest that occurred during the surgical procedure to reduce the diaphragmatic hernia without thromboprophylaxis may have contributed to the peripheral ischemia. HBOT was proposed for the adjuvant treatment of ischemic injury because it is especially indicated for cases of ischemia-reperfusion injury. The main hematological parameters were evaluated at an average interval of 7 days. While the platelet count and hematocrit increased, the leukocytosis decreased. This demonstrates the benefit of oxygen therapy in the reported patient. The use of HBOT in orthopedic injuries is known to result mainly in stimulation of osteoblasts, promoting osseointegration of the prosthesis. We conclude that the adjuvant treatment with HBOT helped to preserve a large segment of both pelvic limbs, prevent the progression of necrosis, and provide a healthy bed for fixation of an osseointegrated prosthesis in the RPL, resulting in clinical improvement of the patient.

Lesão na região metacarpiana do membro torácico esquerdo de bezerra Gir decorrente de contenção para pesagem / Injury in the metacarpinal region of the left thoracic limbs resulting from retention for weighing in a Gir calf

Fraturas ósseas e luxações são mais comuns em animais jovens e, na maioria das vezes, essas fraturas ocorrem devido ao manejo incorreto desses animais, podendo levar a uma queda de produção a curto ou longo prazo, gerando perdas econômicas e produtivas de animais de alto padrão genético. Nesse contexto, o objetivo deste trabalho foi relatar a ocorrência de uma fratura na região metacarpiana do membro torácico esquerdo de uma bezerra Gir de 12 dias de idade, causada por uma contenção ineficaz durante a pesagem. O animal proveniente de uma fazenda em Umirim/CE foi encaminhado ao Hospital Veterinário de Grandes Animais do Centro Universitário INTA em Sobral/CE. Ao passar pelo exame radiográfico, foi constatada a fratura na região metacarpiana do membro torácico esquerdo. O animal foi imobilizado de forma manual, seguindo-se métodos semiológicos para minimizar o estresse. Para a imobilização do membro, foi utilizada a muleta de Thomas modificada e bandagens, associadas ao controle da dor com as drogas Flunixin meglumine (1,1mg/kg) e Fenilbutazona (4,4mg/kg). Depois da imobilização, o animal seguiu internado no HOVET-GA e, após 18 dias, foi realizada uma nova radiografia para ver o progresso a partir do tratamento adotado. Constatou-se a formação de um calo ósseo, com a ossificação da fratura, não sendo necessário o encaminhamento cirúrgico do animal. Assim, o tratamento com muleta de Thomas modificada foi efetivo para a recuperação do membro fraturado, além de ser um tratamento de baixo custo e fácil aplicação, tendo o animal apresentado uma boa resposta ao tratamento terapêutico para controle da dor.

Bone fractures and dislocations are more common in young animals and mostly occur due to incorrect handling of these animals, which can lead to a short or long-term drop in production, generating economic and productive losses of animals of high genetic standard. This study aimed to report the occurrence of a fracture in the metacarpal region of the left thoracic limb of a 12-day-old Gir heifer, caused by an ineffective restraint during weighing. The animal from a farm in Umirim/CE was sent to the Veterinary Hospital of Large Animals of the University Center INTA in Sobral/CE. The radiographic examination found a fracture in the metacarpal region of the left thoracic limb. The animal was manually immobilized following semiological methods to minimize stress. For the limb immobilization, a modified Thomas crutch and bandages associated with pain control with the drugs Flunixin meglumine (1.1mg/kg) and Phenylbutazone (4.4mg/kg) were used. After immobilization, the animal remained hospitalized at HOVET-GA and after 18 days a new radiograph was performed to evaluate the progress achieved with the treatment adopted. It was found the formation of a bone callus with the ossification of the fracture, not requiring the surgical referral of the animal. Thus, the treatment with the modified Thomas crutch was effective for the recovery of the fractured limb, in addition to being a low-cost and easy-to-apply treatment. The animal showed a good response to the therapeutic treatment for pain control.

Curcumin alleviated oxidation stress injury by mediating osteopontin in nephrolithiasis rats

Purpose: To explore the role and mechanism of curcumin (Cur) in reducing oxidative stress damage in rats with nephrolithiasis induced by ethylene glycol (EG). Methods: Thirty male rats were divided into normal control, model, positive (10% potassium citrate), Cur-10 (10 mg/kg curcumin) and Cur-20 (20 mg/kg curcumin) groups. Results: The results of kidney tissue section stained by hematoxylin-eosin and von Kossa showed that curcumin treatment can inhibit the formation of kidney stones. The biochemical test results showed that the urea (Ur), creatinine (Cr), uric acid (UA), inorganic phosphorus and Ca2+ concentrations in urine decreased after being treated with curcumin. There were significant differences between different doses of curcumin (P < 0.05). Compared with the Cur-10 group, Cur-20 had a more significant inhibitory effect on malondialdehyde (MDA) (P < 0.05). In addition, reverse transcription polymerase chain reaction (PCR) detection and immunohistochemical results indicated that the osteopontin (OPN) in the kidney was significantly reduced after curcumin treatment. Conclusion: Curcumin could reduce the oxidative stress damage caused by EG-induced kidney stones.

Fixed bilateral endo-exo prostheses in feline femur - case report / Endo-exoprótese bilateral fixa em fêmur de felino - relato de caso

The use of endo-exo prosthesis is an alternative to improve the quality of life of amputees, allowing correct distribution of body weight, reducing skin problems and pain related to the implant, and reducing lameness. The aim of this paper is to report the use of a fixed bilateral endo-exo femur prostheses in a cat with amputation prior to treatment. The endoprostheses were made with titanium and the exoprostheses were made with 3D printing technology. A longitudinal craniolateral surgical approach was used and the skin incision was made over the knee-joint, then fascia lata incision, followed by biceps femoris and vastus lateralis muscles retraction, incision through the joint capsule to expose the tibiofemoral joint, disarticulation, and tibia and fibula removal. Afterwards, a femoral leveling osteotomy and insertion of the implant in the medullary canal were performed, being attached in the cis and trans cortical bone. The patient was evaluated in the immediate post-operative and periodically thereafter, showing satisfactory results, without macroscopic signs of rejection, wound dehiscence or infection, fracture, or injury of limbs, and presented adapted walking. Furthermore, it was observed the return to common behaviors for the species.

O uso de endoexoprótese é uma alternativa para melhoria na qualidade de vida de pacientes amputados, permitindo distribuição correta do peso corporal, redução de problemas de pele e dor ligadas ao implante e redução da claudicação. Este trabalho objetivou relatar a utilização de endoexoprótese bilateral fixa em fêmur em felino com amputação prévia ao atendimento. Foram modeladas endopróteses em titânio e exopróteses projetadas e impressas em 3D. O acesso cirúrgico, em ambos os membros, foi realizado por incisão craniolateral transarticular da pele, incisão da fáscia lata, rebatimento dos músculos bíceps femoral e vasto lateral, incisão da cápsula articular para exposição da articulação femorotibial, desarticulação e remoção cirúrgica da tibia e da fibula. Em seguida, realizou-se osteotomia niveladora femoral e inserção do implante no canal medular, sendo esse fixo nas corticais cis e trans. O paciente foi avaliado no pós-cirúrgico imediato e posteriormente de forma periódica, demonstrando resultados satisfatórios, sem sinais macroscópicos de rejeição, deiscência ou infecção da ferida cirúrgica, fratura ou lesão de membros, e apresentava deambulação adaptada. Além disso, foi observado o retorno de comportamentos comuns da espécie.

O trauma é frequentemente relatado na rotina clínica de pequenos animais, podendo gerar fraturas de componentes ósseos e lesões de tecidos moles adjacentes. No presente trabalho, objetivou-se relatar o caso de um canino, macho, sem raça definida, de sete meses de idade, vítima de trauma craniomaxilofacial decorrente de mordedura, diagnosticado com fratura e deslocamento de osso zigomático, além de importante laceração de pele. O tratamento estabelecido baseou-se no debridamento da ferida, estabilização cirúrgica de arco zigomático com fios de Nylon e na sutura dos ferimentos de pele causados. Em um segundo tempo cirúrgico, foi realizada enucleação e recobrimento do defeito na órbita com malha cirúrgica de polipropileno, além de remoção de tecido exuberante e confecção de retalho subdérmico de avanço facial lateral para recobrimento do defeito cutâneo. A complicação evidenciada na primeira intervenção cirúrgica foi a deiscência das suturas de pele, enquanto no segundo tempo cirúrgico, não houve sinais de complicações. No pós-operatório, o paciente apresentou evolução clínica satisfatória, recebendo alta médica 21 dias após o segundo procedimento cirúrgico realizado. Tendo em vista a adequada evolução clínica, bem como os reduzidos efeitos colaterais, sugere-se que a conduta clínica e técnicas cirúrgicas adotadas para tratamento do paciente em questão foram efetivas.

Trauma is frequently reported in the small animal clinics, and can lead to fractures of cranial bone components and injuries to the adjacent soft tissues.

The complication observed in the first surgical intervention was dehiscence of the skin sutures, while in the second surgical procedure, there were no signs of complications. Postoperatively, the patient had a satisfactory clinical recovery, being discharged 21 days after the second surgical procedure. Considering the adequate clinical evolution and the reduced complications, it issuggestedthat the clinical conduct and surgical techniques adopted for the treatment of the patient in question were effective.

Inflammation reduction potential of nanostructured lipid carriers encapsulated with rat's bone marrow cells' lysate / Potencial de redução da inflamação de carreadores lipídicos nanoestruturados encapsulados com lisado de células de medula óssea de ratos

Bone marrow-derived mesenchymal stromal cells (BMSCs) have been used for treating inflammatory disorders. Due to the large size of BMSCs compared to nanoparticles, BMSCs cannot be loaded into the nanoparticles. It is hypothesized that BMSCs lysate loading into the nanocarriers will effectively deliver cellular contents and regulatory elements of BMSCs at the injury site. This study aimed to investigate nanostructured lipid carriers (NLC) loading with BMSCs lysate through basic characterization and morphological analysis. Moreover, this study was mainly designed to investigate the role of NLC loaded BMSCs lysate in reducing inflammation via in-vitro and in-vivoassays. The in-vitro study involves cell viability assays, p53, annexin V and VEGF expression through ELISA and immunocytochemistry, real-time BAX, caspase-3, IL-6, IL-8, TOP2A, PCNA, and Ki-67 gene expression analysis. Additionally, to evaluate in-vivo anti-inflammatory activity, the carrageenan-induced rat paw oedema model was used. In-vitro results showed that NLC loaded BMSCs lysate increased cell viability, decreased apoptosis and pro-inflammatory genes expression and up-regulated angiogenesis and proliferation in H2O2 pre-stimulated cells. Findings of the in-vivo assay also indicated a reduction in rat's paw oedema volume in NLC-loaded BMSCs lysate, and downregulation of BAX, Caspase-3, IL-6, and IL-8 was observed. Enhanced expressions of TOP2A, PCNA, and Ki-67 were obtained. Concluding the results of this study, NLC-loaded BMSCs lysate could reduce inflammation and possibly regenerate damaged tissue mainly via increasing cell viability, angiogenesis and proliferation, and reducing apoptosis and pro-inflammatory cytokines.

Células estromais mesenquimais derivadas da medula óssea (BMSCs) têm sido utilizadas para o tratamento de distúrbios inflamatórios. Devido ao grande tamanho das BMSCs em comparação com as nanopartículas, as BMSCs não podem ser carregadas nas nanopartículas. Supõe-se que o carregamento de lisado de BMSCs no nanocarriers será eficaz na entrega de conteúdos celulares e elementos reguladores de BMSCs no local da lesão. Este estudo teve como objetivo investigar a carga de carreador lipídico nanoestruturado (NLC) com lisado de BMSCs através de caracterização básica e análise morfológica. Além disso, este trabalho foi projetado, principalmente, para investigar o papel do lisado de BMSCs carregado com NLC na redução da inflamação por meio de ensaios anti-inflamatórios in vitro e in vivo. O estudo in vitro envolve ensaios de viabilidade celular, expressão de p53, anexina V e VEGF por ELISA e imunocitoquímica e expressão gênica em tempo real de BAX, caspase-3, IL-6, IL-8, TOP2A, PCNA e Ki-67 . Além disso, para avaliar a atividade anti-inflamatória in vivo,o modelo de edema de pata de rato induzido por carragenina foi utilizado. Os resultados in vitro mostraram que o lisado de BMSCs carregadas com NLC aumentou a viabilidade celular, diminuiu a apoptose e a expressão de genes pró-inflamatórios e aumentou a angiogênese e proliferação em células pré-estimuladas com H2O2. Os achados do ensaio in vivo também indicaram uma redução no volume do edema da pata de rato no lisado de BMSCs carregado com NLC, entretando, foi observada a regulação negativa de BAX, Caspase-3, IL-6 e IL-8. Expressões aumentadas de TOP2A, PCNA e Ki-67 foram obtidas. Assim, concluindo os resultados do estudo, é possível afirmar que o lisado de BMSCs carregado com NLC pode reduzir a inflamação e possivelmente regenerar o tecido danificado principalmente por meio do aumento da viabilidade celular, angiogênese e proliferação e redução da apoptose e citocinas pró-inflamatórias.

Pneumocephalus and suppurative meningoencephalitis in a dog after craniofacial trauma

Background: Pneumocephalus is characterized by the presence of gas in the intracranial compartment, and it can be developed by trauma, craniofacial surgery or spontaneously. Clinical signs start within days or months after the injury and vary according to the site of involvement. Computed tomography is the ideal diagnostic tool, however skull radiography can also be used. Treatment varies according to the severity of the case, and it can be conservative or associated with surgical intervention in the most severe cases. The purpose of this report is to describe the case of a dog that developed pneumocephalus and suppurative meningoencephalitis after head trauma caused by a bite from another dog. Case: A 2-month-old bitch, mixed breed, with 3.2 kg, was referred to the Veterinary Hospital because it had been bitten on the head by another dog. Shortly after the incident, the animal showed no clinical signs. However, 2 days later, the bitch became depressed and in persistent lateral decubitus. A lesion with a crust of approximately 0.5 cm was found close to the occipital region, with bone irregularity on palpation. The animal was in lateral decubitus with muscular hypotonia, bilateral mydriasis unresponsive to light and stupor. Radiographic images showed parietal fracture and pneumocephalus. Based on the findings of physical and laboratorial exams, diagnosis of suppurative meningoencephalitis and pneumocephalus secondary to craniofacial trauma was established. Empirical broad-spectrum antimicrobial therapy was started in addition to mannitol, corticoids, and analgesics. The animal was referred for surgical debridement by trepanation, when samples were collected to bacterial culture, which was negative. Despites the care, the animal died 14 h after the surgical procedure. Histopathological examination of the frontal cortex was performed, being the histological changes compatible with suppurative meningoencephalitis. Discussion: Dog bites on the head and neck are particularly severe, and can create intracranial bleeding, disfigurement of the face, damage to peripheral structures or cranial fractures. In this report, through radiographic images, it was found that the patient had an intracerebral aerocele, since there was presence of gas in the intracranial compartment. This alteration should always be considered in animals with neurological alterations and a history of craniofacial trauma. The main neurological changes observed in the reported case were unresponsive to mydriasis and altered mental status 2 days after the trauma, and this delay in the onset of clinical signs is frequently reported in cases of pneumocephalus. Neutrophilia and leukocytosis observed can be justified by the suppurative meningoencephalitis, confirmed by the histopathological exam. Antimicrobial therapy should be started as soon as possible, and the choice must be based on their capacity to cross the blood-brain barrier and the broad spectrum. The administration of antibiotics before collecting the material for bacterial culture may explain the negative result of this test, so that it is not possible to determine whether the intracranial gas observed on the radiograph may have developed from the trauma or because of gas-producing bacteria. Head trauma can induce suppurative meningoencephalitis and pneumocephalus even in the absence of perforating wounds at the time of the consultation. The neurological signs can start days after the trauma. Besides the clinical and surgical treatments, the prognosis of any bacterial infection of the central nervous system is poor.

Eletrocussão em Preguiça-real (Choloepus didactylus) - abordagem clínica e cirúrgica / Electrocution in a sloth (Choloepus didactylus) - clinical and surgical approach

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.

Peixes peçonhentos do baixo Tietê / Venomous fish from baixo Tietê / Pescado venenoso del bajo Tietê

O rio Tietê faz parte de uma das principais hidrovias do Brasil, a hidrovia Paraná ­ Tietê, sendo grande fonte de subsistência para os pescadores que possuem risco na atividade devido peixes que podem causar acidentes traumatizantes e envenenamento por inoculação de veneno por meio de algum aparato ósseo, como ferrão. A arraia fluvial possui ferrão na cauda e causa ferimento de grande importância podendo afastar o pescador de suas atividades por um longo período, devido à demora da cicatrização do ferimento.

The Tietê River is part of one of the main waterways in Brazil, the Paraná ­ Tietê waterway, being a great source of livelihood for fishermen who are at risk in the activity due to fishes that can cause traumatizing accidents and poisoning by inoculation of poison through some bone apparatus, like stinger. The river stingray has a stinger in its tail and causes an injury of great importance, which can keep the fisherman away from his activities for a long period, due to the delay in healing the wound.

El río Tietê forma parte de una de las principales vías fluviales de Brasil, la vía fluvial Paraná - Tietê, una gran fuente de sustento para los pescadores que se encuentran en riesgo en la actividad debido a pescados que pueden causar accidentes traumatizantes y envenenamiento por inoculación de veneno a través de algún aparato óseo, como aguijón. La mantarraya del río tiene un aguijón en la cola y provoca una lesión de gran importancia, que puede alejar al pescador de sus actividades por un largo período, debido al retraso en la cicatrización de la herida.

Expression of TGF-ß/Smads in Cecum and Spleen of Chicken Infected with E. Tenella

Chicken coccidiosis is a common and severe parasitic disease caused by infection from Eimeria spp., which affects the integrity of the intestinal mucosa. TGF-ß has been shown to play an important role in the healing of intestinal mucosas, immunity, and the maintenance of bowel mucosa integrity. Very little is known about the presence of the components of TGF-ß/Smads signaling pathway of chicken at different times following coccidian infection. In the present study, we measured the levels of TGF-ß2, 3, 4, receptor TßRI, II, down-stream Smad 2, 3, 7 in cecum and spleen of chicken at different times after inoculation with Eimeria tenella using quantitative real-time PCR. The results showed that the TGF-ß/Smads signaling pathway was not activated in cecum in the early stage of infection. However, on the 8th day, the expression of TGF-ß2, 4, down-stream protein Smad 2, 7 were significant up-regulated in the spleen, which indicated that the TGF-ß/Smads signaling was changed in the E. tenella infection and was differentially expressed in various tissues in the early stages of infection.(AU)

Fratura de úmero em uma curicaca (Theristicus caudatus) - manejo anestésico e cirúrgico / Humerus fracture in a buff-necked ibis (Theristicus caudatus) - anesthesia and surgical procedures

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.

Hip dislocation in a calf - treatment with iliofemoral suture

Background: Coxofemoral dislocation is uncommon in large animals, due to anatomical particularities that provide greater stability to this joint. The most common causes of hip dislocation in large animals are related to hypocalcemia, mount trauma, sudden falls on hard surfaces or dystocia. Treatment can be performed by closed reduction, but the reported results are not satisfactory with complications. Several surgical techniques have already been described and successfully used in small animals in the treatment of hip dislocation. The present work aims to describe the technique and the result of the iliofemoral suture in the treatment of hip dislocation in a Girolando heifer. Case: A heifer was attended with a history of difficulty in getting up. According to the owner, the clinical manifestation was sudden, after remaining in a paddock with other animals of different age groups. The calf had reduced skin sensitivity on the croup, and it was impossible to remain in the quadrupedal position, often remaining in sternal recumbency with the left pelvic limb in extension. From the clinical examination, spinal cord injury was suspected and clinical treatment was instituted with dexamethasone, vitamins B1, B12 and dimethylsulfoxide. At the end of the clinical treatment, the animal did not show a favorable evolution, so radiographic examination of the coxofemoral region was performed, revealing dislocation of the left femoral head, indicating surgical correction. Xylazine was administered as pre-anesthetic medication, followed by anesthetic induction with midazolam associated with ketamine, followed by orotracheal intubation. Anesthetic maintenance was instituted with isoflurane and monitoring was performed with a multiparameter monitor. An epidural block was performed with bupivacaine and morphine. A craniolateral approach to the left hip joint was performed. After the dislocation was reduced, sutures were used to better stabilize the joint in question. Following the evolution of the surgical procedure, it was possible to confirm that the femoral head remained in place. After 15 days, the skin stitches were removed and the animal was discharged from the hospital and returned to its original property. The calf was asked to remain in the stall for at least 60 days, gradually releasing it into larger spaces and only after 120 days could it remain in the paddock with other animals. During three months, the tutor was consulted about the evolution of the condition, reporting that the animal was clinically well, being able to get up and walk without difficulty and with a mild degree of lameness, thus suggesting the success of the surgical procedure. Discussion: There are few studies of successful surgical treatments of hip dislocation in large animals, and that number is even smaller when considering cattle alone. It is believed that this is due to difficulties related to the surgical technique and to postoperative handling, given the animal's weight. The iliofemoral suture technique performed on the animal in the present study is commonly employed in small animals, and excellent results have been observed. However, reports on the use of this technique in large animals have not been found. The iliofemoral suture technique has advantages over other reported surgical techniques in cattle. When compared to the femoral head and neck resection, the iliofemoral suture has several advantages, as it allows preservation of the joint and achievement of superior biomechanical results. When compared to the technique of reinforcement of the joint capsule with synthetic material, also reported in cattle, the iliofemoral suture appears to be faster, simpler and more economic, and provides similar stability. We conclude that the iliofemoral suture proved to be a satisfactory alternative for the treatment of hip dislocations in young cattle.

Enostose múltipla em equino puro sangue de corrida / Enostosis-like lesion in thoroughbred horse

Background: Enostosis like lesions are characterized by areas of intramedullary sclerosis affecting the long bones andtheir presence in any cases may be not associated with lameness. It has a migratory characteristic and, therefore there isthe occurrence of lameness at different sites from the initial lesion. Its etiology is speculative and has been attributed tointraosseous increased pressure, of Havers’ canals compression, stimulation of unmyelinated fibers and circulating plateletaggregates. Diagnosis is made through nuclear scintigraphy and associated with radiographic examination. This paperaims to report a clinical case on the use of scintigraphy for the reference diagnosis of enostosis-type injury and treatmentthrough surgical bone decompression.Case: A 2-year-old thoroughbred mare, weighing 483 kg, with a history of acute lameness of the left pelvic limb associatedwith the no previous signs of trauma and no noteworthy changes in radiographic and ultrasound images, was referred to theHorse Center Veterinary Clinic. In the examination of the locomotor system, the animal presented a 2/5 degree lamenessin a straight line, with accentuated exacerbation of the same after flexion of the left femoro-tibio-patellar joint. In addition,presented a reduction in the caudal phase of the stride and croup asymmetry associated with mild myopenia. The findingsof the scintigraphic exam characterized by intense focal area of hyperconcentration of medullary radiopharmaceutical inthe proximal third of the right third metatarsal, and multiple areas of hyperconcentration in the aspect proximal to thedistal third of the left tibia. In the radiographic images, multifocal radiopaque regions that coincided with the areas ofradiopharmaceutical hyperconcentration were observed. The initial treatment was based on rest, use of non-steroidal antiinflammatory drugs and acetylsalicylic acid. In the 60 days...

Compressive lesions in the central nervous system of cattle: a retrospective study of 50 cases in the Amazon biome / Lesões compressivas no sistema nervoso central de bovinos: um estudo retrospectivo de 50 casos no bioma amazônico

The present study gathered epidemiological and clinical-pathological information about cattle with compressive lesions in the central nervous system (CNS). The retrospective study included observations made in 50 cattle from 1998 to 2021 by reviewing the clinical records of animals with compressive lesions in the CNS treated at the Veterinary Hospital of the Veterinary Medicine Institute of the Federal University of Pará. The animals had clinical signs and were subjected to general and specific clinical examination of the nervous system. Blood samples were collected from 13 animals for complete blood counts, and cerebrospinal fluid (CSF) samples were collected from four animals for physical evaluation. Twenty-nine cattle underwent necropsy. The most affected sites were the T3-L3 (46%, 23/50), C1-C5 (22%, 11/50), C6-T2 (14%, 7/50), sacrococcygeal vertebrae, (4%, 2/50), L4-S2 (2%, 1/50), brain (8%, 4/50) and cerebellum (4%, 2/50). The age of the affected cattle ranged from 20 days to 16 years, with a higher occurrence in animals younger than 12 months (56%, 28/50). More Females were affected (58%, 29/50) than males (42%, 21/50). The clinical signs varied according to the location of the lesion and were mainly represented by ataxia, paresis or paralysis of the limbs, inability to stand and walk, postural changes, hyperesthesia in the extremities, and loss of skin sensitivity at the location of the lesion. The necropsy findings revealed changes such as abscesses in the vertebral body; intervertebral space in the medullary canal, pituitary and cerebellum; granuloma in the arch of the vertebra; fractures of the body of the vertebrae; subarachnoid haematoma; congenital bone alteration causing spinal cord compression; and spondylitis. Detailed anamnesis and clinical examination of the CNS, associated with necropsy findings, were important to determine the cause of the disease, correlate with the clinical picture and locate the affected segments of the CNS in the cattle. It is important to include these diseases in the list of differential diagnoses in cattle with nervous symptoms.

O estudo retrospectivo compreendeu as observações realizadas em 50 bovinos durante os anos de 1998 a 2021, por meio da revisão dos arquivos de fichas clínicas de animais com lesões compressivas no SNC atendidos pelo Hospital Veterinário do Instituto de Medicina Veterinária da Universidade Federal do Pará. Os animais atendidos com sinais clínicos foram submetidos a exame clínico geral e específico do sistema nervoso. Foram coletadas amostras de sangue de 13 animais para realização de hemograma e amostras de líquido cefalorraquidiano de quatro animais para avaliação física. Foram submetidos à necropsia 29 bovinos. Os locais mais acometidos foram as vértebras T3-L3 (46%, 23/50), C1-C5 (22%, 11/50), C6-T2 (14%, 7/50), sacrococcígea (4%, 2/50) e L4-S2 (2%, 1/50); cérebro (8%, 4/50) e cerebelo (4%, 2/50). A idade dos bovinos afetados variou de 20 dias a 16 anos, com maior ocorrência em animais com menos de 12 meses (56%, 28/50). As fêmeas foram mais acometidas (58%, 29/50) do que os machos (42%, 21/50). Os sinais clínicos variaram de acordo com a localização da lesão e foram representados principalmente por ataxia, paresia ou paralisia dos membros, incapacidade de se levantar e de ficar em estação, alterações posturais, hiperestesia nas extremidades, além de perda da sensibilidade cutânea relacionada com a localização da lesão. Os achados de necropsia revelaram alterações como abscessos no corpo vertebral, no espaço intervertebral, no canal medular, para-hipofisário e no cerebelo; granuloma no arco da vértebra, fraturas do corpo das vértebras; hematoma subaracnoide; alteração óssea congênita causando compressão medular e espondilite. Anamnese detalhada e exame clínico do SNC, associados aos achados de necropsia foram importantes para determinar a causa da doença, correlacionar com o quadro clínico e localizar os segmentos acometidos do SNC dos bovinos. Torna-se importante incluir estas enfermidades na lista de diagnósticos diferenciais em bovinos que apresentem sintomatologia nervosa.

Avaliação da eficácia do sistema rigeneracon no tratamento de lesões de calvária em ratos / [Evaluation of the efficacy of the rigeneracon system in the treatment of calvary injuries in rats]

Defeitos ósseos constituem um problema de saúde global. O sistema Rigenera permite a extração de microenxertos ricos em células-tronco mesenquimais (CTMs). Objetivou-se avaliar o processo de regeneração óssea por enxertos obtidos pelo sistema Rigenera em defeitos críticos na calvária de ratos. Foram utilizados 18 ratos Wistar, machos, pesando 285±29g, distribuídos em três grupos (n=6), sendo cada animal controle de si mesmo, denominados G15-Controle e G15-Tratado (15 dias); G30-Controle e G30-Tratado (30 dias) e G60-Controle e G60-Tratado (60 dias). Foram realizadas duas lesões de 5mm de diâmetro em cada antímero da calvária. Nos grupos tratados, foram utilizados microenxertos autólogos de cartilagem xifoide, obtidos pelo sistema Rigenera. O defeito contralateral serviu como controle em todos os animais. Os animais foram eutanasiados aos 15, 30 e 60 dias após a cirurgia, e as amostras foram processadas para a histoquímica. Nos grupos controle, não foram observados sinais de regeneração óssea, enquanto nos grupos tratamento foram verificadas áreas de formação óssea e tecido mesenquimal ativado. O sistema Rigenera foi eficiente na obtenção de microenxertos autólogos, para terapia celular em defeito crítico de calvária de ratos. Com o aprimoramento do protocolo, o sistema Rigenera poderá ser amplamente utilizado no tratamento de lesões ósseas.(AU)

Bone defects are a global health problem. The Rigenera system allows the extraction of micro grafts rich in mesenchymal stem cells (MSCs). The objective of this study was to evaluate the bone regeneration process by grafts obtained by the Rigenera system in defects in the rats calvarian. Eighteen male Wistar rats were used, weighing 285 ± 29g, distributed in three groups (n = 6), where each animal was treatment and control, called G15-Control and G15-Treated (15 days); G30-Control and G30-Treated (30 days) and G60-Control and G60-Treated (60 days). Two 5mm diameter lesions were performed on each calvaria side. In the treated groups, autologous micrograft from xiphoid cartilage, obtained by the Rigenera system, were used. The other defect served as a control in all animals. The animals were euthanized at 15, 30 and 60 days after the surgery and the samples were processed for histochemistry. In the control groups, no signs of bone regeneration were observed, while in the treatment groups, areas of bone formation and activated mesenchymal tissue were verified. The Rigenera system was efficient in obtaining autologous micrograft for cell therapy in a critical calvaria defect in rats. Rigenera system can be widely used in the treatment of bone injuries.(AU)

Cervical ventral slot in rabbits (Oryctolagus cuniculus). Piezosurgery versus conventional technique

ABSTRACT Purpose To investigate the applicability of piezosurgery for cervical ventral slot (CVS), comparing it with the conventional technique of using high-speed burs for bone wear. Methods Thirty rabbits (Oryctolagus cuniculus) were divided into two treatment groups (T1 and T2) corresponding to CVS between C3-C4. In T1, the surgery was performed with piezoelectric apparatus, and in T2 with high-speed burs. The evaluated parameters were: duration of each stage of surgery, temperature variations during CVS, visibility of the surgical field, intra and postoperative complications, and anesthetic monitoring. At 14, 28, and 56 postoperative days, five animals from each treatment group were submitted for histopathological study of the surgical site. Results Compared with T2, T1 had more precise bone cut, and better visibility of the operative field, although it required longer total surgical time (p = 0.02) and triggered a greater number of intraoperative complications (p < 0.01), microscopic lesions in the spinal cord (p < 0.05), and transient neurological deficits in the postoperatively (p < 0.05). Conclusions It is necessary to perform surgical planning and have several tips of the piezoelectric instrument available for the safe use of the piezoelectric device in neurosurgery.

BM-MSC-derived small extracellular vesicles (sEV) from trained animals presented nephroprotective potential in unilateralureteral obstruction model

Background: The efficacy of bone marrow mesenchymal stromal cells (BM-MSC) and its extracellular vesicles has been demonstrated for a broad spectrum of indications, including kidney diseases. However, BM-MSC donor characteristics and their potential are not usually considered. Therefore, the present work aims to evaluate the nephroprotective capacity of sEV secreted by BM-MSC from trained rats inunilateral ureteral obstruction (UUO) model. Methods: BM-MSC was characterized by their differentiation potential and immunophenotypic markers. The sEV were isolated by ultracentrifugation and characterized by nanoparticle tracking analysis and western blot. Its miRNA cargo was examined by quantitative PCR analysis for miR-26a, 126a, and 296. Wistar rats were submitted to UUO procedure and concomitantly treated with sEV secreted by BM-MSC from the untrained andtrained rats. The kidney tissue from all groups was evaluated for fibrosis mediators (transforming growth factor beta1 and collagen), CD34-angiogenesis marker, and hypoxia-inducible factor 1 alpha (HIF-1α). Results: Treadmill training stimulated in BM-MSC the production of sEV loaded with pro-angiogenic miR-296. The treatment with this sEVin UUO-rats was able to attenuate collagen accumulation and increase CD34 and HIF-1α in the kidney tissue when compared to untrained ones. Tubular proximal cells under hypoxia and exposed to BM-MSC sEV demonstrate accumulation in HIF-1α and NFR-2 (nuclear factor erythroid 2-related factor 2), possibly to mediate the response to hypoxia and oxidative stress, under these conditions. Conclusion: The BM-MSC sEV from trained animals presented an increased nephroprotective potential compared to untrained vesicles by carrying 296-angiomiR and contributing to angiogenesis in UUO model.(AU)
