Background: Gastropexy is used to correct gastric dilatation volvulus, a disease that usually affects large and giant dogs and leads to death in 23.4 - 43% of patients. This study aimed to evaluate the biomechanical traction of 2 gastropexy techniques, incisional gastropexy and scarified gastropexy, in 10 dog cadavers. Incisional gastropexy comprises a single incision in the abdominal wall and another incision in the stomach wall in the pyloric region followed by simple continuous sutures. The scarification technique creates scarification along the stomach borders of the pexy. Thereby, knowing that both techniques are successful, the biomechanical traction of each technique was compared. Materials, Methods & Results: A total of 10 animals without defined breed weighing from 6.4 - 43.0 kg were allocated into 2 equal groups (GE [scarified gastropexy] and GI [incisional gastropexy]). Incisional gastropexy was performed with a simple continuous suture pattern in the GI group and scarified gastropexy with an interrupted simple suture pattern was performed in the GE group. Absorbable 2-0 monofilament yarn (polygllecaprone 25) was used for sutures in both groups. Rectangular segments of the gastric antrum were collected from the right abdominal wall and from the bottom of the stomach at the left abdominal wall, which were subjected to a traction test. The scarification technique was easier, faster, and used less surgical sutures than the incisional technique. Both techniques were effective regardless of the site applied, with no significant differences. There was a difference in stretching depending on location. Discussion: The pathogenesis of gastric dilatation volvulus (GDV) is unknown. However, gas accumulation inside the gastric chamber may lead to organ dilation and consequently cause torsion of the cardia region and pyloric antrum, resulting in strangulation of blood vessels and nerves. This torsion could cause stomach ischemia followed by organ necrosis if early emergency care is not provided. In addition, vessel strangulation my lead to a systemic syndrome resulting in shock. The disease presents acute and non-specific clinical signs such as weight loss, vomiting, and abdominal intumescence. Patients with risk factors such as reduced gastric motility, delayed stomach replenishment, lower weight, advanced age, or presence of a foreign body may present with poor prognosis. Once GDV becomes an emergency, surgical correction with the most efficient surgical techniques and procedures is necessary to guarantee patient survival. Based on the results obtained, both the scarified and incisional gastropexy techniques are more efficient than other techniques. In addition, the scarified technique with interrupted simple stitches stood out when compared to the incisional technique with a continuous simple suture pattern as it was faster and used less suture thread. The incisional technique, on the other hand, provides good juxtaposition of the edges of the wounds, avoiding the exposure of muscle tissue, as well as adhesions from other organs. The knowledge of those factors promotes positive effects on the effectiveness of an emergency surgical approach for patients with GDV, since it allows less surgical time, as well as less anesthetic time. Based on the results obtained during the biomechanical traction tests of the study, it was concluded that both scarified gastropexy with interrupted single stitches and incisional gastropexy with a continuous single stitch may be efficient. The scarified technique stood out when compared to the incisional technique as it required less time and used less sutures. [ABSTRACT FROM AUTHOR]

In the skin, when healing by first intention is not possible due to excess tissue tension, the best option becomes the use of reconstructive surgical techniques such as flaps and grafts. The use of grafts or flaps, greatly reduces the healing time of the lesions, in addition to minimizing the risks of possible infections. In addition, due to the great frequency of multiple traumatic, cutaneous and bone injuries that occur in small animals after running over and their innumerable treatment options, which makes it sometimes difficult to choose the best behavior for these patients, the objective was to describe the treatment of a traumatic wound, using modified Robert Jones' sugar, followed by total thickness mesh cutaneous graft, in a dog that had an extensive infected cutaneous wound and open metatarsophalangeal luxation, emphasizing the functional return of the limb. The canine patient, was submitted to the second intention treatment of the wound until it was able to receive cutaneous grafting. The results were satisfactory, with complete wound healing and functional limb reestablishment with 120 days of treatment. It is concluded that the combination of conservative and surgical treatments can be an efficient alternative to limb amputation in the treatment of infected lacerated wound associated with complete joint dislocation, generating satisfactory functional and aesthetic results.

The celiac, cranial mesenteric and celiacomesenteric ganglia of the paca (Cuniculus paca) were found between the celiac and cranial mesenteric arteries. Two predominant patterns were found: isolated celiac and cranial mesenteric ganglion and the celiacomesenteric ganglion. At the microscopic level, the ganglia are constituted by an agglomeration of neurons surrounded by capsule of connective tissue. Most of these neurons had a single eccentric nucleus. Satellite cells and mast cells were found around the soma. The mast cells were also found ar ound blood vessels and in the capsule of the ganglia. [ABSTRACT FROM AUTHOR]

The study reported the influence of the high and acute dose of Letrozole on the testis morphology in paca (Cuniculus paca), an aromatase inhibitor that reduces the endogenous estrogen, the essential hormone for spermatogenesis. Morphological changes were observed in seminiferous epithelium with germ cells with apoptotic characteristics and presence of vacuoles and nuclei in pycnose. [ABSTRACT FROM AUTHOR]
