Resumo

Milk and its derivatives are rich in nutrients and widely consumed by the population. However, the presence of chemical residues is frequent in these products. This study aimed to carry out a diagnosis of the use of antibacterials and evaluate the knowledge about these drugs and behaviors adopted by dairy producers in Goiás, Brazil. A total of 286 dairy farms in 36 municipalities in the State were visited and interviews were conducted with the owner or auxiliary workforce. The questions addressed the production parameters of the property and the use of antibacterials. The answers were presented in percentages and graphs. Statistical analysis was performed using Pearson's chi-square test at a 5% significance level. Only 26.2% of the producers used antibacterials indicated by veterinarians and all producers (100%) disposed of milk with residues inappropriately. Tetracycline and penicillin were the most used among the 21 cited active principles. Enteritis (22.1%), cattle tick fever (21.1%), and mastitis (19.4%) were the main diseases treated with antibacterials. A total of 37.4% of respondents were unable to distinguish antibacterials from other drugs. Moreover, the more specialized the farm, the greater the veterinary assistance and the greater the care for antibacterial treatments. Most respondents (51.7%) had incomplete elementary education. These results provide important information about how rural producers in the State of Goiás use antibacterials and serve as a basis for future interventions. The need for greater access by producers to veterinary services in Goiás is evident to reduce the unnecessary and inappropriate use of antibacterials.(AU)


O leite e seus derivados são ricos em nutrientes e largamente consumidos pela população. Contudo, a presença de resíduos de substâncias químicas é frequente nesses produtos. Esse estudo objetivou realizar um diagnóstico sobre o uso de antibacterianos, avaliar o conhecimento sobre esses fármacos e condutas adotadas por produtores de leite em Goiás, Brasil. Foram visitadas 286 propriedades leiteiras em 36 municípios do estado, onde foram realizadas entrevistas com o proprietário ou mão de obra auxiliar. As perguntas abordavam parâmetros produtivos da propriedade e uso de antibacterianos. As respostas foram apresentadas em porcentagem e gráficos. A análise estatística foi realizada pelo teste de qui-quadrado de Pearson ao nível de significância de 5%. Apenas 26,2% dos produtores utilizavam antibacterianos indicados por veterinários e todos (100%) descartavam o leite com resíduos de forma inadequada. Dentre os 21 princípios ativos citados, os mais utilizados foram as tetraciclinas e penicilinas. As principais doenças tratadas com antibacterianos foram enterite (22,1%), tristeza parasitária bovina (21,1%) e mastite (19,4%). Observou-se que 37,4% dos entrevistados não souberam distinguir antibacterianos de outros medicamentos. Verificou-se que quanto mais especializada é a fazenda, maior é a assistência veterinária e maiores os cuidados para tratamentos com antibacterianos. A maioria dos entrevistados (51,7%) apresentava ensino fundamental incompleto. Esses resultados fornecem informações importantes sobre como os produtores rurais do estado de Goiás utilizam antibacterianos e servem como base para intervenções futuras. É evidente a necessidade de maior acesso dos produtores a serviços veterinários em Goiás, a fim de reduzir o uso desnecessário e inadequado de antibacterianos.(AU)

Background: Omphalophlebitis is characterized as an omphalopathy that affects the umbilical vein. In these cases, ultrasonography can help identify the severity of abdominal lesions and guide the choice of treatment. Marsupialization of the umbilical vein is a surgical procedure indicated in cases where this vessel presents with purulent secretion up to the liver parenchyma. This report describes a case of omphalophlebitis in a calf treated by marsupialization of the umbilical vein. The preoperative and postoperative sonographic findings are also described. Case: A 4-day-old Holstein calf was attended at the Veterinary Hospital (HV) of the Universidade Federal de Goiás (UFG), Goiânia, Brazil. On physical examination, the animal was found to be apathetic, with tachycardia, tachypnea, hyperthermia, hyperemic mucous membranes, and moderate dehydration. An increase in volume was observed in the umbilical region, with local hyperthermia, firm consistency, and sensitivity to palpation. On deep palpation of the abdomen, a mass originating in the umbilical region and extending cranially was observed, leading to the suspicion of omphalophlebitis. Abdominal ultrasonography revealed external umbilical abscess and omphalophlebitis. Initially, conservative treatment with antibacterial and anti-inflammatory drugs was performed; however, there was no improvement in the clinical picture. Therefore, exploratory celiotomy was performed to remove the umbilical infectious focus. During the procedure, it was verified that the umbilical vein was dilated with a thickened wall until its insertion in the hepatic parenchyma, hence removal of the infected region through a ligature was not possible. Thus, marsupialization of the umbilical vein was performed to create a cutaneous opening for drainage of the purulent contents. In the postoperative period, antibacterial, anti-inflammatory, and analgesic drugs were administered. Dressing of the surgical wound and of the umbilical vein lumen was performed with topical polyvidone at 0.2%. Removal of the stitches was done 14 days postoperatively. Weekly ultrasonographic examinations were performed, which showed a gradual reduction in the diameter of the umbilical vein throughout the postoperative period. Thirty days after the surgical procedure, no further drainage of the purulent content was observed from the umbilical vein, and healing of the stump was demonstrated. After 7 months, a repeat ultrasonography was performed, revealing normal echogenicity and echotexture of the hepatic parenchyma and complete atrophy of the umbilical vein. Discussion: Umbilical vein marsupialization is a surgery rarely described in the literature, and no report has followed the evolution of a case by ultrasonography. The ultrasound examination of the umbilical structures was essential for the definitive diagnosis and choice of surgical treatment. Marsupialization of the umbilical vein was chosen due to the impossibility of ligature of this vessel, which presented with thickened walls and lumen filled with purulent content until its insertion into the liver. Postoperative monitoring via serial ultrasonography examinations allowed follow up of the evolution of the case and animal recovery. At the sonographic reevaluation after 7 months, the findings were unremarkable, indicating complete recovery of the patient. Umbilical marsupialization is a surgical technique that allows complete recovery of calves with severe omphalophlebitis. Ultrasonography is fundamental for the diagnosis of omphalophlebitis and in determining the best therapeutic protocol. Sonographic evaluation during the postoperative period allows follow-up of the progression of lesions in abdominal structures and helps in defining the prognosis.
