In TPLO, the block commonly used is the sciatic nerve block associated with the femoral nerve block. In orthopedic surgeries in human medicine, the iPACK block associated with the adductor canal block has been used as alternatives that do not affect the strength of the quadriceps femoris muscle. The objective of this study was to evaluate the trans and postoperative analgesic effect of the association of iPACK block and adductor canal block, as well as to evaluate the patient’s motor recovery after surgery. Four patients were selected, without distinction of breed and gender, weighing more than 22lb, referred to TPLO. All patients underwent the combination of iPACK block and adductor canal block with 0.5% bupivacaine. The intraoperative evaluation was carried out by measuring mean arterial pressure, heart rate and respiratory rate, and all patients were stable during the procedure. The postoperative evaluation was carried out based on the assessment of pain using the modified Glasgow scale, in which all patients scored less than 05/24, and assessment of ambulation through videos using the adapted Muzzi scale, presenting ambulation between grade 1 and 2. No patient required intraoperative or postoperative analgesic rescue.</p> Desirée Santos da Rosa Isabele de Matos Oliveira Laryssa Reginaldo Ribeiro da Silva Yasmin Santos Kaulich de Souza Gustavo Nunes de Santana Castro Copyright (c) 2024 Desirée Santos da Rosa, Isabele de Matos Oliveira, Laryssa Reginaldo Ribeiro da Silva, Yasmin Santos Kaulich de Souza, Gustavo Nunes de Santana Castro 2024-06-05 2024-06-05 46 e002324 e002324 10.29374/2527-2179.bjvm002324 Granular cell tumor of the brachial nerve in a dog: A case report <p>Here, we describe the first case of a granular cell tumor (GCT) derived from the brachial nerve. Elevenyear-old neutered female Chihuahua presented to the hospital with a bulge from the left neck to the axilla. The dog had a spherical subcutaneous mass on the cervical subcutis, and cytology hinted at adenocarcinoma or neuroendocrine tumor. However, the origin of the tumor remains unknown. During resection of the mass, bleeding was difficult to control owing to the high blood flow, and tumor removal was extremely difficult. The caudal aspect of the mass was attached to the brachial nerve and had to be removed, along with parts of the nerve fibers. The patient’s postoperative course was fair, but it developed paralysis of the left thoracic limb. Pathology revealed that the mass was positive for S100 and vimentin, and GCT was diagnosed. Non-oral GCTs are extremely rare. The clinical diagnosis of GCT is difficult and is often confirmed histopathologically by excision. Although most cases of GCT are benign, they must be recognized as hemorrhagic, indistinct masses that mimic malignancy. Excision carries the risk of hemorrhage and damage to the surrounding tissues to secure margins.</p> Maeda Maeda Seiichi Wada Chiaki Shimaoka Satomi Iwai Shozo Okano Copyright (c) 2024 Maeda Maeda, Seiichi Wada, Chiaki Shimaoka, Satomi Iwai, Shozo Okano 2024-05-28 2024-05-28 46 e001424 e001424 10.29374/2527-2179.bjvm001424 Fasciolosis in ruminants in Brazil <p>This review aims to promote discussion about the situation of fasciolosis in ruminants in Brazil. The disease is still found more frequently in the South and Southeast regions, but reports outside these areas show the spread of the disease, including human cases. Many studies have been published on the diagnosis and control of fasciolosis, but development of field diagnosis methods and drugs that control all stages of the parasite is still a challenge. Studies should be carried out of new distribution areas and alternatives for control in Brazil, which depends on understanding the complex interactions between of the environment, ecosystems and hosts of this trematode.</p> Isabella Vilhena Freire Martins Natânia do Carmo Sperandio Copyright (c) 2024 Isabella Vilhena Freire Martins , Natânia do Carmo Sperandio 2024-05-21 2024-05-21 46 e002924 e002924 10.29374/2527-2179.bjvm002924 Assessment of infection of Stomoxys calcitrans larvae by entomopathogenic nematodes Heterorhabditis amazonensis NEPT11 <p>This study aimed to evaluate the virulence of <em>Heterorhabditis amazonenses </em>NEPT11 against larvae of <em>Stomoxys calcitrans</em>. Groups of 10 third-instar fly larvae were deposited in Petri dishes, to which were added 50, 100 and 200 EPNs/larva in 4ml of distilled water. The volume of the control group was the same as the treated group, but without EPNs. Larval mortality was observed daily, until larvae died or adults emerged. The Petri dishes were kept on laboratory shelves at 27 <strong>± </strong>1 °C and 70 ± 10% RH. The experiment was replicated six times. A regression analysis revealed quadratic behavior with increasing concentrations, indicating that the concentration of 200 EPNs/larva (48%) was the most efficient among the tested concentrations, while concentrations of 50 and 100 EPNs/larva killed 26.6 and 40% of larvae, respectively. In general, none of the treatments resulted in a mortality rate of more than 50%, but all the treated groups exhibited a higher mortality than that of the control group. It is concluded that the EPN <em>H. amazonensis </em>NEPT11 shows a promising potential to control third-instar larvae of <em>S. calcitrans</em>. However, further studies are needed in different situations to better understand the activity of this organism against the immature stages of the stable</p> Américo de Castro Monteiro Sobrinho Ana Caroline Ferreira de Souza Danielle Pereira da Silva Gabriela Pereira Salça de Almeida Vinícius Teixeira de Souza João Luiz Lopes Monteiro Neto Melissa Carvalho Machado do Couto Chambarelli Copyright (c) 2024 Américo de Castro Monteiro Sobrinho, Ana Caroline Ferreira de Souza, Danielle Pereira da Silva, Gabriela Pereira Salça de Almeida, Vinícius Teixeira de Souza, João Luiz Lopes Monteiro Neto, Melissa Carvalho Machado do Couto Chambarelli 2024-04-05 2024-04-05 46 e000424 e000424 10.29374/2527-2179.bjvm000424 Description of the parasitic fauna of a specimen of Didelphis albiventris at Rio Grande do Sul <p><em>Didelphis albiventris </em>is considered the most common marsupial in Rio Grande do Sul. With omnivorous and synanthropic habits, it can serve as a host to various parasites, playing an important role in maintaining their biological cycle. Despite being a widespread and abundant species, it has a relatively little-known parasitic fauna. Therefore, the aim of this study was to report the diversity of parasites in a fecal sample from <em>D. albiventris </em>in Rio Grande do Sul, Southern Brazil. Modified Centrifugal-flotation and Spontaneous sedimentation techniques were used, revealing a high taxonomic diversity of parasites. Eggs of <em>Ancylostoma </em>spp., <em>Toxocara </em>spp., and Anoplocephalidae were reported for the first time in the host in the southern region of the country, along with the first report of pseudoparasitism by <em>Syphacia </em>spp. and <em>Monocystis </em>spp. in this animal species. The presence of different parasites in the feces of <em>D. albiventris </em>is of utmost importance, primarily for public health, but also for understanding the biodiversity of parasites present in wildlife, which has been poorly studied until now. This allows the implementation of effective strategies for controlling, preventing and treating these diseases.</p> Julia Somavilla Lignon Diego Moscarelli Pinto Silvia Gonzalez Monteiro Natália Soares Martins Julia Victória de Souza Giulia Ribeiro Meireles Tamires Silva dos Santos Felipe Geraldo Pappen Fábio Raphael Bruhn Copyright (c) 2024 Julia Somavilla Lignon, Diego Moscarelli Pinto, Silvia Gonzalez Monteiro, Natália Soares Martins, Julia Victória de Souza, Giulia Ribeiro Meireles, Tamires Silva dos Santos, Felipe Geraldo Pappen, Fábio Raphael Bruhn 2024-04-02 2024-04-02 46 e000524 e000524 10.29374/2527-2179.bjvm000524
