Ultrasonography-guided oocyte recovery in owl monkeys (aotus azarai infulatus).

The study evaluated an echo-guided oocyte recovery technique in owl monkeys. Twelve females were selected for the transabdominal ovum retrieval technique. This procedure collected twenty-six follicles, of which nine oocytes were recovered, without harm to the animals. The technique is feasible and is a minimally invasive protocol for neotropical primates.

Gastroesophageal foreign bodies in dogs - endoscopy and surgical removal

Background: Gastroesophageal foreign bodies (GFD) are commonly diagnosed in dogs and are considered an endoscopic emergency that, although not resulting in serious clinical sequelae or mortality, can compromise the health and well-being of the patient. The use of the digestive endoscopy for the diagnosis and treatment of GFD can be a valuable and viable alternative. There are cases of GFD in dogs for which the indicated treatment is surgery, which can be performed using minimally invasive or conventional techniques, associated or not with flexible endoscopy. The objective of this work is to describe 16 cases of GFD removal in dogs demonstrating the efficiency of upper digestive endoscopy. Cases: Of the 16 GFD cases, 63% (10/16) were male and 37% (6/16) female. Most aged under 1 year (63%), puppies (5/16) and juveniles (5/16). The patient with the lowest body weight was a miniature pinscher weighing 0.8 kg (Case 14) and the heaviest was an American Pit Bull Terrier weighing 28 kg (Case 11), the mean body weight of patients diagnosed with GFD was 10.2 ± 6.7 kg. Small and medium breeds were more affected, 44.7% (7/16) and 44.7% (7/16), respectively, and large breeds (Golden Retrievier and Bull Terrier), from cases 1 and 4, the least affected, 12.6% (2/16) of the cases. The 16 patients underwent a 12 h food fast and a 4 h water fast, as gastrointestinal emptying in these cases of GFD can be influenced by these foreign bodies. All underwent general inhalation anesthesia with monitoring of physiological parameters (temperature, heart rate, respiratory rate, oxygen saturation and blood pressure) before, during and after EGD, being positioned in left lateral decubitus. The 16 canine patients with suspected GFD underwent EGD for diagnostic confirmation and removal of foreign bodies. Five esophageal FB were diagnosed, 31% (5/16), and 11 gastric FB, 69% (11/16). The most frequently diagnosed foreign bodies were bone and tissue, 37.5% (6/16) and 31% (5/16). Other foreign bodies were materials such as plastics, metals, rubber, foam and stone. Of the 16 cases of GFD, EGD efficiently treated 88% (14/16) without the need for hospitalization, with only supportive treatment for the remission of complications caused by the presence of foreign bodies in the gastroesophageal tract. The main complications related to the presence of GFD were esophagitis in 25% (4/16) of cases, gastritis in 38% (6/16) and both alterations in 13% (2/16). Discussion: In this work, we can observe that more than a third of the clinical cases of treated dogs were diagnosed with GFD, demonstrating that these cases are common in the veterinary clinic. Most of these animals were males less than 1 year old. The improvement of learning in this category can lead these animals to exacerbated oral exploration of new objects. Most FBs were found in the stomach because they were of adequate size, consistency and shape for their passage through the esophagus, whereas esophageal FBs were all bone fragments of rigid consistency with diameters and sizes larger than the esophageal lumen. The interval between the ingestion of the object and the veterinary care can be decisive for the removal of the FB in the esophagus or stomach. Most gastric FBs removed were fabrics and plastics, flexible objects that can pass through the esophageal lumen more easily. Removal of GFD by endoscopy was performed with a high success rate, with only 2 cases being resolved by esophagostomy and gastrotomy. Flexible endoscopy proved to be an efficient technique for removing treated GFD, which can help remove FB during esophagotomy and be associated with rigid endoscopy. Patients recovered quickly and without complications, but it is important to emphasize that inadequate maneuvers and conducts can determine other outcomes. The use of endoscopy for GFD removal needs to be more popularized, as it can ensure better results for dogs treated with GFD.

Subcutaneous advancement flap for snout reconstruction after traumatic injury in a dog: case report / Retalho em avanço de padrão subdérmico para reconstrução de focinho após lesão traumática em canino: relato de caso

Reconstructive plastic surgery in companion animals is increasing in surgical blocks. Pedicle skin flaps on the face of dogs and cats are of difficult execution, making it challenging for the surgeon. The objective of this work is to report a skin reconstruction of a dog's face after trauma. A male dog of unknown breed, presenting trauma of unknown cause with total loss of snout and part of incisive bone, was attended at the Veterinary Hospital of the Federal University of Pará, Brazil. Emergency care was performed and the animal was referred for surgical debridement of the lesion and posterior plastic correction. A subcutaneous facial advancement flap was used to cover the wound, demonstrating that this is a good option in this region due to the low elasticity of the skin. There were no intercurrences in the postoperative period and the animal presented good functional and cosmetic results.(AU)

A cirurgia plástica reconstrutiva em animais de companhia vem cada vez mais tomando espaço dentro do bloco cirúrgico. Retalhos pediculados de pele em face de cão e gato são de difícil execução tornando-se desafiador para o cirurgião. O objetivo deste trabalho é relatar a reconstrução cutânea de face de um cão após trauma. Foi atendido no Hospital Veterinário da Universidade Federal do Pará um cão, macho, sem raça definida, apresentando trauma de causa desconhecida com perda total de focinho e parte de osso incisivo. Foi realizado o atendimento emergencial e encaminhado para desbridamento cirúrgico da lesão e posterior correção plástica. Foi realizado um retalho de padrão subdérmico de avanço facial para cobertura da ferida, demonstrando este ser uma boa opção nessa região devido à pouca elasticidade da pele. Não houve intercorrências no pós-operatório e o animal apresentou bons resultados funcionais e cosméticos.(AU)
