Background: Hydrodissection is a minimally invasive procedure that consists of injecting fluid into an anatomical space to facilitate dissection during surgery. Although this procedure is employed in several areas of veterinary medicine, including ophthalmology, there are no reports of the use of this maneuver in conjunctival procedures in dogs. The use of this technique can facilitate the construction of conjunctival pedicle flaps, thereby improving the results. The purpose of this work was to evaluate the use of hydrodissection in the construction of conjunctival pedicle flaps in dogs. Materials, Methods & Results: The sample consisted of 20 eyes from 10 healthy dogs that had been subjected to elective surgical procedures of ovariohysterectomy and orchiectomy. The dogs were divided into 2 groups; the 1st group of 10 eyes underwent hydrodissection and the 2nd group of 10 eyes did not. All the patients underwent a complete ophthalmic examination and assessment of their systemic conditions. The patients were then anesthetized and the procedures were performed under a surgical microscope. In the group subjected to hydrodissection, the conjunctival flap was prepared by means of a previous subconjunctival injection of 0.7 mL of 0.9% sodium chloride, followed by preparation of the flap. In the group without hydrodissection, the flap was prepared by means of conventional divulsion using iris scissors. After producing the conjunctival flaps, a conjunctival fragment was collected from both groups for histological analysis and evaluation of the presence of the Tenon capsule. The operating time, degree of hemorrhage and ease of handling the conjunctiva in the intraoperative period were evaluated. Postoperative evaluations were performed at 1, 7 and 14 days after surgery and included: blepharospasm, conjunctival hyperemia and edema, which were classified as absent, mild, moderate or severe; tear production was evaluated using the Schirmer test, and the appearance of the conjunctival scar was assessed based on photographs taken in the postoperative period, and by a visual analogue scale, with healing classified as fair, good or excellent. The 2 groups showed no statistical difference in terms of operating time, bleeding, ease of handling and conjunctival divulsion. A volume of 0.48 ± 0.12 mL of 0.9% sodium chloride was administered to the conjunctiva. Postoperative assessments of hyperemia, blepharospasm, conjunctival edema, and tear production also did not differ statistically. Conjunctival scarring was considered optimal until the 14th postoperative day, with no statistically significant difference between the 2 groups. These results demonstrate that both maneuvers are effective in creating conjunctival flaps. The Tenon capsule could not be identified in histological stains. Discussion: The literature offers numerous descriptions of the use of hydrodissection in surgical procedures in humans in order to facilitate dissection and reduce surgical duration and handling, thereby improving the clinical recovery of patients. Conversely, this technique has not been described frequently in veterinary medicine, notably with respect to conjunctival procedures. In this study, we demonstrated that conjunctival hydrodissection was perfectly feasible, contributing to the divulsion and preparation of conjunctival flaps, thus proving to be a viable option for this type of procedure. The absence of the Tenon capsule in the evaluated samples demonstrates that, in both groups, the techniques were effective in separating them from the conjunctiva. It was therefore concluded that the hydrodissection technique is a feasible maneuver in the construction of conjunctival flaps, providing a new option for surgeons, especially for novice ophthalmologists.

The product quality is a competitive advantage that plays a differential role among companies. In the food industry, which is based on the Quality Management System, such as Good Manufacturing Practices (GMP), which cover the hygiene procedure, aiming at food safety. In view of the above, the aim of this study was to evaluate the hygienic-sanitary conditions of a selected dairy from the São Luís Island - MA. An application of the checklist was performed, swab collection from the hands of the manipulators and equipment and the collection of water and yogurt for microbiological analysis. After this step, a training was performed for food handlers and finally, new collections and microbiological analysis were performed. All the microbiological analysis performed were satisfactory, except for the water sample, one before and again for training. It can be verified that the hygienic-sanitary condition of the dairy was good. However, after a lecture and new microbiological analyzes, improvements were observed in the results.(AU)


A qualidade dos produtos é uma vantagem competitiva que desempenha um papel diferencial entre empresas. Na indústria alimentar, faz-se necessária a adoção do Sistema de Gestão de Qualidade, como as Boas Práticas de Fabricação (BPF), que abrangem os procedimentos essenciais de higiene, visando à segurança alimentar. Diante do exposto, objetivou-se avaliar as condições higiênico-sanitárias de um laticínio selecionado da ilha de São Luís, Maranhão. Foi realizado um checklist, coleta por swabs das mãos dos manipuladores e de equipamentos e coleta de água e iogurte para análises microbiológicas. Após essa etapa, foi executado um treinamento para os manipuladores de alimentos e, por fim, novas coletas e análises microbiológicas foram realizadas. Todas as análises microbiológicas realizadas mostraram-se satisfatórias, com exceção da amostra de água, uma antes e outra após o treinamento. Pode-se constatar que a condição higiênico-sanitária do laticínio era boa. Contudo, após uma palestra e a realização de novas análises microbiológicas, foram observadas melhorias nos resultados.(AU)

Background: Fibrosarcomas are malignant neoplasms originating from fibroblasts that are normally located in the skin, subcutaneous tissue and adjacent to bones. The main treatment for fibrosarcoma is surgery. The removal of large neoplasms from dogs’ limbs usually leads to the formation of large skin defects, often preventing primary occlusion and thus requiring reconstructive surgery to close the wound. This paper reports on the surgical procedure and postoperative complications pursuant to the excision of a fibrosarcoma in the right forelimb and reconstruction with a full-thickness autologous graft in a dog. Case: A 12-year-old Brazilian mastiff presenting a nodule located in the distal segment of the right forelimb, which had grown over a 2-year period, was referred for clinical evaluation. Blood and imaging tests were performed, which showed no changes and excluded the possibility of metastasis. The cytological examination was suggestive of a mesenchymal neoplasm. The patient underwent tumor excision surgery followed by reconstructive surgery with a full-thickness autologous graft to close the defect. The neoplasm was excised by means of a circular geometric figure incision using a 3 cm margin. The defect resulting from removal of the tumor was kept constantly moistened and wrapped in surgical compresses until grafting was performed. The graft was harvested from the region of the right flank based on a surgical field mold taken from the recipient bed. After harvesting the graft, all the subcutaneous tissue was removed until the hair follicles were visible. Fenestrations were then made throughout the entire graft and it was placed in the recipient bed and...

A identificação das condições higiênico-sanitárias do pescado é de suma importância para a promoção da saúde e a qualidade de vida da população. Dessa forma, o presente trabalho teve como objetivo avaliar a qualidade microbiológica e verificar o perfil de susceptibilidade a antimicrobianos das cepas isoladas de amostras de tambaqui (C. macropomum) comercializadas na cidade de São Luís, Maranhão. As 60 amostras de tambaqui, obtidas de supermercados e feiras livres, foram analisadas quanto à determinação do Número Mais Provável (NMP) de coliformes totais e termotolerantes; pesquisa de Escherichia coli; pesquisa de Aeromonas spp., e perfil de resistência antimicrobiana. Foi detectada uma elevada contagem de coliformes totais e termotolerantes, além de bactérias patogênicas, tais como: Aeromonas spp. em 56 (93,3%) e E. coli, em 13 (43,3%) das amostras analisadas. Em relação ao perfil de resistência antimicrobiana, os isolados de E. coli demonstraram baixos percentuais de resistência e as cepas de Aeromonas apresentaram elevados níveis de resistência aos antimicrobianos testados. Pode-se concluir que o tambaqui comercializado em São Luís − MA apresenta condições higiênico-sanitárias inadequadas para o consumo.

Background: Encephalitis is common in most inflammatory and infectious diseases of the central nervous system, andbacterial and viral pathogens, protozoa, fungi, and erythematous parasites are recognized as etiological agents. Clinicalsigns vary according to the anatomical location and severity of the inflammation. Some parasites may undergo aberrantmigration into the brain of dogs and cats, which is are considered a rare clinical phenomenon. This case report describesthe occurrence of parasitic encephalitis in a mixed breed bitch about 4 year-old.Case: A mixed breed bitch, about 4 year-old, rescued from the street with weakness of the pelvic limbs, was treated at theVeterinary Hospital of the Federal University of Piauí - UFPI. After A clinical and neurological examination, the patientwas hospitalized for diagnosis, treatment, confirmation and follow-up of her clinical evolution. Complementary tests wereperformed to evaluate her general condition, given her unknown history because she was a rescue dog. Complete blood count(CBC), hemoparasite screening, biochemical function (urea, creatinine, ALT, alkaline phosphatase, total protein, albuminand globulin), abdominal and pelvic ultrasound, serological and parasitological tests for leishmaniasis, distemper antigenand ehrlichiosis antibody detection tests were performed, and cerebrospinal fluid (CSF) was collected for analysis. TheCBC revealed normocytic hypochromic anemia and thrombocytopenia. Biochemical functions were within normal limits,except for alanine aminotransferase (ALT), which was slightly low. The ultrasound examination showed splenomegaly.The canine distemper, ehrlichiosis and leishmaniasis tests were negative. The results of the CSF analysis revealed the presence of spherical structures compatible with parasitic cysts, suggestive of Echinococcus granulosus. After the laboratorydiagnosis of parasitic encephalitis, the animal was treated with prednisolone...
