Encarceramento nefroesplênico de cólon ascendente esquerdo em equinos : revisão de literatura
(Fundação de Ensino Octávio Bastos, 2023-10-18) TAGLIAFERRO, Karoline Saturnino; OLIVEIRA, Braian Rombaldo de; RIBEIRO, Amanda
Colic syndrome in horses is characterized as pain of acute abdominal origin, which can originate from various diseases in abdominal organs, however, in the vast majority of cases, the origin of the pain is disorders in the gastrointestinal tract (GIT). Among these diseases of the GIT is the displacement of the left ascending colon and its incarceration over the nephrosplenic ligament. This displacement is characterized by the entrapment of the pelvic flexure in the nephrosplenic ligament, and the main predisposing factor for this to occur are the muscles themselves. anatomical characteristics of the region. This condition can lead to mild, moderate or severe pain, causing physical changes, mainly in heart rate, respiratory rate and intestinal motility pattern. Diagnostic methods for nephrosplenic incarceration include the association of findings on physical examination, transrectal palpation and transabdominal ultrasound examination. However, it is worth highlighting that, in certain cases, only the surgical procedure confirms the diagnosis. In the case of an established clinical diagnosis, the main drug therapy applied to these cases is the administration of epinephrine in the form of an infusion, in an attempt for this alpha-2 adrenergic agent to lead to splenic contraction, and the ascending colon to return to its normal anatomical position. . In some cases, this attempt at splenic contraction does not produce positive results, leaving the surgical procedure as the only treatment. The objective of this work is to address, through a literature review, the main aspects of the nephrosplenic entrapment in horses, through a clinical and surgical approach taking into account tells current literary data.
Enterectomia parcial de íleo secundária a hérnia inguinoescrotal em garanhão: relato de caso
(Fundação de Ensino Octávio Bastos, 2023-10-18) LINO, Estefany Zerbeto Basilio; MEGALE, Rafael dos Santos; RIBEIRO, Amanda
Inguinoscrotal hernias account for around 7% of cases of colic syndrome in stallions and are mainly associated with the passage of a segment of small intestine into the scrotum through the inguinal ring. The clinical signs resulting from inguinoscrotal hernias are signs of colic (acute pain of abdominal origin) and the degree of pain can vary from moderate to severe. Associated with intestinal injuries, there is testicular involvement, which is evidenced by the degree of pain upon palpation of the testicles, the decrease in local temperature and ultrasound findings. To make the diagnosis, it is essential to associate physical changes with ultrasound changes in the scrotal and abdominal region. Inguinoscrotal hernia in stallions is a surgical emergency, this is due to the vascular compromise that occurs in the herniated intestinal segment, which leads to a severe degree of hypoxia and organic dysfunction. of this segment. This results in the need to perform an enterectomy on the affected portion, which occurs via exploratory celiotomy. Associated with this procedure, orchiectomy and herniorrhaphy are performed as surgical treatment. The objective of this work is to report the case of a stallion undergoing exploratory celiotomy due to incarceration of the ileum resulting from an inguinoscrotal hernia. The animal was treated at the Vicente Borelli Veterinary Hospital - UNIFEOB, in São João da Boa Vista, where the orchiectomy, herniorrhaphy and subsequent partial enterectomy of the ileum and enteroanastomosis were performed.
Enucleação transpalpebral em equino submetido a anestesia total intravenosa: relato de caso
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2019-09-18) COSTA, Beatriz S.; ZOGBI, Thays C. S. Cruz; MELO, Victória de; RIBEIRO, Amanda; MARTINS FILHO, Luís Paulo
Horses are often affected by eye injuries that can compromise their vision to a greater or lesser extent. The ophthalmological pathologies that these animals present have different etiologies, which can be vascular, inflammatory, neoplastic or traumatic. The present report aims to describe the transpalpebral enucleation technique as a means of effective treatment based on a case report in a female horse, treated at the Veterinary Hospital of Fundação de Ensino Octávio Bastos, after traumatic evisceration of the eyeball.
Falha na trasferência de imunidade passiva em neonato equino: Relato de caso
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) SILVEIRA, Ana Claudia Cassiano; COELHO, Bruno Machioni; RIBEIRO, Amanda
Failure of passive transfer of immunity (FTIP) is a relatively common immune condition in equines, as the newborn needs maternal antibodies, originating from colostrum, to have immunological protection in the first weeks of life, which is called passive immunity. The antibodies present in colostrum are immunoglobulins and are transferred to the newborn only in the first hours of life through the ingestion of colostrum. This colostrum is formed approximately 30 days before parturition and is essential for the maintenance of the foals' lives, being able to maintain significant serum levels of immunoglobulins up to 90 days of life. In many cases, the newborn foal does not ingest colostrum or ingests a small volume, and this may be related to several factors, from difficulty in standing up, difficulty in suckling, pre-existing diseases from intrauterine life and even failure in the production of colostrum by the mare. Failure to ingest colostrum results in FTIP and can lead to dehydration, hypoglycemia and later to infections or even sepsis, in the first hours of life. In these cases, the foal may die if not treated quickly. Therefore, this study aims to report a case of FTIP in a newborn horse treated at the UNIFEOB Veterinary Center.
Síndrome da reabsorção odontoclástica e hipercementose equina: Revisão de literatura
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) TODERO, Larissa M.; RIBEIRO, Amanda
Equine odontoclastic resorption and hypercementosis syndrome (EOTRH) is a painful and progressive condition that affects the incisor and canine teeth of geriatric horses. Since its etiopathogenesis has not yet been fully resolved, this disease often ends up being underdiagnosed. Several theories of etiology have been considered for this disease, however, none of them have been fully accepted. Histologically, EOTRH presents with the resorption of tooth structures by odontoclasts, usually followed by the deposition of altered cementum, by odontoblasts, cementoblasts and fibroblasts. To diagnose this syndrome, a detailed clinical oral examination and the use of radiographic examination are necessary, since the signs may often not be visible at the beginning of the disease. Clinical signs are varied, and range from pain and lack of food apprehension with incisors, to more serious changes, such as changes in the angles of the incisors and tooth fractures. On radiographs, it is possible to observe resorption changes in the teeth, with lysis of the reserve crown and root and proliferative changes, such as deposition of cementum and expansion of the alveolar bone. In addition, alveolitis, osteomyelitis and periodontal changes are also found. There is no effective treatment for EOTRH, and extraction of the affected teeth is almost always indicated.
Torção de raiz do mesentério em equino isquemia e reperfusão: Revisão de literatura
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) OLIVEIRA, Braian Rombaldo de; GOBESSO, Gabrielle Bordonal; RIBEIRO, Amanda; BRITO, Pedro Henrique Salles
Mesenteric root torsion is a disease in which the mesentery root rotates. It can be explained by the large length of the horse's intestine, its anatomical positioning and variations in the intestinal lumen. It can even be correlated with the species' own intestinal anatomy and is characterized by the rapid formation of gases in the intestinal lumen (resulting from microorganisms present in the intestine and as a consequence of the ingestion of highly fermentable substances). Another important factor is the characteristic of its diet, with the fermentation process being an important part of its digestion, indirectly promoting the distension of intestinal loops. This condition can cause severe vascular impairment and lead to severe hypoxia, which can trigger cellular damage and consequent cell death and tissue necrosis. The tissue injury caused by torsion leads to compromise of the intestinal mucosa, favoring the inflammatory process and bacterial translocation, that is, favoring the migration of bacteria from the intestinal lumen to the circulation and even to the peritoneum, with the main complications being endotoxemia, Systemic Inflammatory Response Syndrome (SIRS) and sepsis. This study aims to conduct a survey of data from the literature on the effects of ischemia and intestinal reperfusion damage in the face of mesenteric root torsion in horses.
