Item Osteossarcoma em cães: revisão de literatura(Fundação de Ensino Octávio Bastos, 2023-10-18) HONÓRIO, Vinicius M.; CUSTÓDIO, Mariana M.; RODRIGUES, Rafaela F.; GONÇALVES, Brenna M.C. N.Osteosarcoma (OSA) is the most common malignant bone neoplasm found in small animal clinics, being locally invasive, rapidly metastatic and aggressive in nature. Histologically it is composed of anaplastic mesenchymal cells that produce osteoid. It generally affects the long bones found in the appendicular skeleton of large dogs.giant size, between 5 and 9 years old, but can also affect bones of the axial skeleton such as ribs, vertebrae, skull and jaw bones. The animal will present with acute or chronic pain, lameness and edema in the affected limb. Due to bone weakness, pathological fractures may occur during the development of the disease. Although the diagnosis of OSA is normally based on clinical history and radiographic findings, histopathological examination and cytology are necessary for more reliable confirmation. To prevent this neoplasm from reaching other regions, it is It is recommended to amputate the affected limb, with a safety margin, associated with chemotherapy or radiotherapy sessions, with the aim of prolonging the animal's life and well-being. To control pain, the use of analgesics and non-steroidal anti-inflammatory drugs can be essential, but in most cases it is necessary to use opioids. The prognosis is generally poor, but will depend on how the animal responds to treatment. The objective of this review is to report on neoplasia in issue, in order to allow you to provide quality of life for the affected dog.Item Microambiente tumoral angiogênese(Fundação de Ensino Octávio Bastos, 2023-10-18) FURLAN, Ana Paula; VARGAS, Thiago Henrique MoroniThe tumor microenvironment is a complex and dynamic environment that involves not only cancer cells, but also a variety of stromal cells, extracellular molecules and blood vessels. Among the many biological processes that occur in the tumor microenvironment, neovascularization, or the formation of new blood vessels, plays a fundamental role in cancer progression. Tumor angiogenesis is regulated by several soluble factors, including vascular endothelial growth factor (VEGF), which is produced by both cancer cells and surrounding stromal cells. These soluble factors stimulate the formation of new blood vessels in the tumor, providing nutrients and oxygen to cancer cells and allowing them to grow and spread to other parts of the body. The study of the tumor microenvironment and Angiogenesis has been the subject of much research, with the aim of developing new cancer therapies that target these biological processes and improve treatment efficacy.Item Manejo alimentar inadequado e sua relação com a lipidose hepática em psitácideos: revisão de literatura(Fundação de Ensino Octávio Bastos, 2023-10-18) FARIA, Alex Takahashi de; DOMENCIANO, Heloisa Helena Ferreira; AIUB, Plinio B.Currently, exotic and wild species have gained space as pets. Due to their behavior, psittaciformes or parrots (parrots, cockatiels, Australian parakeet, for example) example) are commonly found as pets and are consequently present in the routine of veterinarians specializing in unconventional pets. Factors such as The owner's inexperience, lack of veterinary monitoring and the inappropriate way of acquiring the animal result in errors in food management. Offering a diet rich in fatty seeds and lacking in nutrients is associated with the incidence of diseases arising from incorrect diet and among them, liver diseases, more precisely, hepatic lipidosis. This disease is characterized by excessive accumulation of fat in the liver, with different etiologies, with the individual being able to or not demonstrate clinical signs and biochemical changes.Item Métodos diagnósticos da endocardite bacteriana em cães: revisão de literatura(Fundação de Ensino Octávio Bastos, 2023-10-18) OLIVEIRA, Braian Rombaldo de; PELITEIRO, Lívia; ALBERTO, Maryna Lança ViliaBacterial endocarditis is an infectious process that affects the heart valves, most commonly, mitral and aortic located on the left side, or the endocardium itself. The animals The most affected are medium or large male dogs, due to the occurrence of prostatitis subacute or chronic bacterial infection, which can also affect small dogs, both males and females. In most cases, the clinical signs of the disease are not specific (such as hyperthermia, weight loss, loss of appetite, polydipsia, polyuria, tachypnea, dyspnea, and exercise intolerance), which makes early diagnosis even more difficult. Positive blood culture results are used as diagnostic methods, along with the relationship between the most involved microorganisms, as well as echocardiography, electrocardiogram, radiography, blood count and necropsy. Among the treatment methods, the recommended therapeutic protocol is the use of broad-spectrum antibiotics that penetrate fibrin, always maintaining them for long periods, and can be administered intravenously and orally, always following the results of the blood culture and antibiogram, without ever forget to periodically evaluate possible coexisting problems that may appear as a result of bacterial endocarditis. Therefore, the objective of this work is to compile data from the literature, highlighting the different methods for diagnosing bacterial endocarditis.Item Lúpus eritematoso discóide em cão: relato de caso(Fundação de Ensino Octávio Bastos, 2023-10-18) FELIX, Juliana Simões; PRATES, Rafaela Gonçalves; MARTINELLI, Paulo Edson BaptistaDiscoid Lupus Erythematosus (DLE) is one of the most common autoimmune skin diseases in small animal clinics, with a high prevalence, especially in dogs. Its etiology is not yet well defined, however it is possible to state that hormonal and genetic factors influence the onset of DLE, as well as sun exposure, especially in light areas of the body, as this disease results in depigmentation, peeling and erythema of the skin. The diagnosis is made based on anamnesis, physical and histopathological examination, and its differentials include pemphigus foliaceus and actinic dermatitis. Being an autoimmune condition, there is no cure, however, the prognosis is favorable when the lesions are controlled through the use of corticosteroids, sun protection and vitamin E supplementation. The present work aims to describe a clinical case diagnosed as DLE in a two-year-old female dog.Item Intussuscepção em potra mangalarga: relato de caso(Fundação de Ensino Octávio Bastos, 2023-10-18) ALVES, Karolina Cupim Gonçalves; SCARPION, Lorena Bueno; PAIVA, Lívia Maria da Silva; CELOTTI, GustavoEquine intussusception is defined as intussusception that mainly affects foals up to three years old. The condition is invagination of the segment of one organ into another segment the same. Characterized by intense, acute and severe abdominal pain. The diagnosis can be made through complementary tests, such as collection of peritoneal fluid, rectal palpation (when possible) and mainly through ultrasound examination, which can observe the small intestine. Treatment is clinical and may be surgical, depending on the severity of the injury. In more serious cases, which present severe congestion due to strangulation of the loop, enterectomy and enteroanastomosis are necessary to remove the part of the segment without functionality and with circulatory unviability. Through this work, we propose to report a case of jejunojejunal intussusception in a filly, with surgical resolution, treated at the UNIFEOB Veterinary Hospital.Item Uso do plasma rico em plaquetas no tratamento da tendinite equina: revisão de literatura(Fundação de Ensino Octávio Bastos, 2023-10-18) SILVA, Laila M.; Flório, Naiara S.; PESSINATI, Bárbara D.Equine tendonitis is an important pathology, which mainly affects high-performance animals and is characterized by tendon inflammation. The clinical signs of the disease are classified as edema and increase in local temperature, pain on palpation of the affected region and lameness. Its definitive diagnosis is made through ultrasound, a complementary exam considered the most reliable for this disease. Treatments can be classified as conventional, through rest, use of anti-inflammatories, cryotherapy and bandages, and alternative, such as the use of Platelet Rich Plasma (PRP). PRP is a product derived from the animal's own blood, in which we find a high concentration of platelets, and when administered intralesionally, they degranulate, releasing growth factors that assist in cell differentiation, promoting increased production of type I collagen, providing better tendon repair, strength and elasticity. The objective of this work is a literature review on the use and effects of PRP in the treatment of tendon injuries in horses.Item Importância e métodos de conservação do axalote (Ambystoma mexicanum) in situ e ex situ : revisão de literatura(Fundação de Ensino Octávio Bastos, 2023-10-18) OLIVEIRA, Giovani Vinícius de; RODRIGUES, Paulo Daniel; AIUB, Plinio B.The axolotl is an aquatic amphibian native to Mexico, known for its ability to regenerate and its peculiar appearance. However, its wild population has been declining due to habitat loss, water pollution and illegal trapping. To ensure the survival of axolotls, in situ (in the natural environment) and ex situ (in captivity) conservation strategies are necessary. In situ conservation involves the protection and management of natural habitats, while ex situ conservation involves captive breeding and maintenance of populations. Both approaches play complementary roles in preserving the species, allowing the maintenance of genetic diversity, carrying out scientific research and developing reintroduction strategies into the wild.Item Vírus da influenza aviária e seus impactos socioeconômicos(Fundação de Ensino Octávio Bastos, 2023-10-18) CARVALHO, Bárbara; NUNES, Alanne TenórioAvian Influenza (AI) is characterized as a zoonosis and infectious disease of birds caused by the type A influenza virus. The high level of genetic recombination between members of the AI virus of this type allows gene permutations and causes the emergence of new virus strains. All types of H5N1 viruses have a row of basic amino acids at the hemagglutinin (HA) cleavage site and are fatal to chickens, generating systemic infections. Considering the relevance of this topic, the present work aimed to clarify the disease, its clinical signs, diagnosis and treatment, in addition to highlighting its economic repercussions. The results of the literature review demonstrate the need to employ biosafety measures in environments of poultry farms, so that Brazil maintains its status as an AI-free country for trade.Item Estudo morfológico dos dentes do puma concolor(Fundação de Ensino Octávio Bastos, 2023-10-18) LEITE, Debora Brenda Silva; CAROCI, Camila de Abreu; LUCA, Giovanna Matos de; BERALDI, Maria Vitória; MANÇANARES, Celina Almeida FurlanettoThe Puma concolor is a feline that lives solitary and has day and night habits. Classified as a species threatened with extinction in Brazil since 2014, the decline of the species could cause numerous changes to the ecosystem. This study seeks to identify the species' dental arch, as any problem in the oral cavity can lead to behavioral changes, systemic dysfunctions and compromising the animal's health. The study described the position and structure of the teeth in the dental arch, and to carry out macroscopic analyzes of the teeth, incisions were made in the skin, removing the facial muscles for exposure and for better clarity of photodocumentation. The teeth were extracted using surgical instruments. The identified dental formula was 2X (I 3/3, C 1/1, PM 3/2, M 1/1) = 30 teeth in the permanent dentition. It was observed that the second molar of the Puma concolor is located more medially compared to the domestic cat, although the anatomy of domestic and wild felines is similar. This study aims to compare some information with existing data, contributing to knowledge about the dental morphology of this species and providing material for future research.
