Reducción de homicidios en Minas Gerais: un análisis del programa «Fica Vivo!»

Este artículo presenta los resultados de una investigación cualitativa sobre la contribución del programa «Fica Vivo!» al control y reducción de los homicidios en Minas Gerais (Brasil), según la percepción de los actores sociales e institucionales involucrados. La metodología se basó en entrevistas semiestructuradas y grupos focales con los gerentes y monitores de los talleres, líderes comunitarios y profesionales de la seguridad pública y la justicia penal. En estas conversaciones emergieron una serie de tensiones relacionadas con las funciones sociales de los actores del programa, es decir, el equipo técnico y los profesionales de seguridad pública. Así, entre los asuntos en disputa destacan las percepciones sobre los objetivos del programa y el flujo de información entre la comunidad y el equipo, en una dinámica que no siempre incluye a la Policía.Traductora: Ester Jiménez de Cisneros Puig

Primary Pulmonary Adenocarcinoma in a Cow

Background: Primary neoplasms of the respiratory tract are rare in cattle, and they present with nonspecific clinical signs and are usually found at post-mortem. Pulmonary adenocarcinoma of the acinar type is uncommon, and information about this neoplasm in cattle is scarce. This paper aims to describe the clinical, laboratory, and pathological findings in a cow with this neoplasm.Case: A 10-year-old, adult, mixed-breed Holstein cow weighing 300 kg was referred to the Garanhuns Cattle Clinic of the Campus of Federal Rural University of Pernambuco, Brazil, with a history of decreased appetite, tiredness, weight loss, and difficulty in breathing for two months. The animal had been treated at the farm of origin with enrofloxacin, florfenicol, and flunixin meglumine. The animal’s appetite improved, but no improvement in the respiratory symptoms was observed. On examination at our center, the cow was in an orthopedic position, with neck extension and elbow abduction; and it remained in a recumbent position. The cow had neutrophilia, normochromic normocytic anemia, and hyperfibrinogemia. The body condition score (BCS) was 1 (BCS ranges from 1 to 5), and the cow had moderate enophthalmia, serous secretions in nostrils, tachycardia, and tachypnea. It also had increased breathing intensity; increased breath sounds in the cranial regions of both lungs; areas of reduced breath sounds in the medial portions of the lungs; intermittent wheezing in the cranial region of the left lung medially and in the cranial region of the right lung medially; intermittent crepitations in the cranial region of the right lung medially; reduced thoracic expansion; and expiratory dyspnea. Pulmonary ultrasonography revealed hyperechogenic multifocal structures in both lungs. In view of the severe clinical condition and unfavorable prognosis, the owner opted for euthanasia. Necropsy revealed that there was a significant amount of yellow fluid in the thoracic cavity, and the cut surfaces of the lungs were covered with fibrin and pleural adhesions. The lungs had irregular surfaces with multifocal nodules of various sizes and firm consistency. The texture of the cut nodules was solid, and the nodules had a yellowish color. Histologically, the pulmonary nodules were composed of neoplastic cells. They were pleomorphic, infiltrative epithelial cells with little cytoplasm; large and spherical nuclei with abundant euchromatin; occasional anisokaryosis; visible nucleolus; and numerous mitotic figures. Results of anti-cytokeratin immunohistochemistry were strongly positive for cytokeratin in the lungs and lymph nodes. Discussion: The diagnosis of acinar pulmonary adenocarcinoma was based on clinical, laboratory, histopathological, and immunohistochemical findings. Clinical signs and lung ultrasound suggested a severe respiratory disease. Pulmonary tumors are usually solid, and they show areas of central necrosis that resemble granulomas. However, the histopathological findings in the current case were compatible with a primary pulmonary neoplasm. Primary pulmonary neoplasms, although rare, should be considered in the differential diagnosis of weight loss, cachexia, and respiratory symptoms in adult cattle. The morphological pattern and the strong immunoreactivity on immunohistochemical examination were conclusive for a diagnosis of a primary pulmonary adenocarcinoma of the acinar type because these tumors specifically contain cytokeratin

Primary abomasal impaction in 14 cattle from Pernambuco State, northeastern Brazil

Apesar de forragens grosseiras e secas serem empregadas comumente na alimentação de vacas em várias regiões, especialmente durante o período seco, a compactação primária do abomaso tem sido pouco relatada no Brasil, provavelmente pela dificuldade de diagnóstico dos veterinários de campo. Este trabalho objetivou realizar um estudo retrospectivo sobre a compactação primária do abomaso em 14 bovinos no Estado de Pernambuco. Oito casos considerados moderados, sem grave distensão abdominal e sem compactação do rúmen, foram tratados conservativamente e quatro casos graves, com severa distensão abdominal e compactação do rúmen, foram tratados cirurgicamente. Um touro foi encaminhado para abate e uma vaca morreu antes de receber qualquer tratamento. O maior número de casos de compactação do abomaso ocorreu em bovinos da raça Holandesa com seis casos (42,9%), seguido por animais mestiços com cinco casos (35,8%) e as raças Pardo-Suiça, Nelore e Marchigiana com um caso cada (21,3%). A composição da alimentação oferecida caracterizou-se por conter fibra de baixa qualidade e variou bastante dentre os casos. Os sinais clínicos mais frequentes foram comportamento apático, desidratação, timpanismo ruminal associado à hipomotilidade, distensão abdominal, hipomotilidade intestinal e fezes escassas ou ausentes com presença de muco. Os achados hematológicos revelaram, na maioria dos casos, leucocitose por neutrofilia e hiperfibrinogenemia. Na análise do fluido ruminal havia comprometimento da dinâmica da flora e fauna microbiana, e elevação no teor de cloreto. O índice de recuperação clínica (4/8) e cirúrgica (2/4) observado neste estudo foi de 50%. As condutas clínica e cirúrgica permanecem como opções viáveis para o tratamento das compactações leves e severas, entretanto o prognóstico é considerado reservado, principalmente quando associado à gestação avançada.Despite the frequent use of dry and fibrous roughage for feeding cows in many regions, especially during the dry season, impaction of the abomasum has been poorly reported in Brazil, probably because the condition is misdiagnosed by practitioners. The present paper aimed to accomplish a retrospective study on primary abomasal impaction in 14 cattle from Pernambuco State, northeastern Brazil. Eight moderate cases, without severe abdominal distention and with no rumen compaction, were treated conservatively, and four severe cases, with severe abdominal distention and rumen compaction, were treated surgically. One bull was slaughtered and one cow died without treatment. The greater number of abomasal impaction cases was in Holstein cows with six cases (42.9%), followed by crossbred cattle with five cases (35.8%), and the breeds Brown-Swiss, Nelore and Marchigiana, each with one case (21.3%). The food composition was characterized by low quality fibers and varied greatly among cases. Most frequent clinical signs were apathy, dehydration, hypomotility and ruminal bloat, intestinal hypomotility and scanty or absent feces with mucus. The hematological findings revealed leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. Ruminal fluid analysis showed compromised flora and fauna dynamics and increased chlorine ion concentration. Clinical (4/8) and chirurgical (2/4) recovery rate achieved 50%. The clinical and chirurgical methods remain as viable options for the treatment of light and severe impaction, but the prognosis is always reserved especially when associated to late pregnancy

FATORES DE RISCO RELACIONADOS À OCORRÊNCIA DO TIMPANISMO ESPUMOSO EM BOVINOS CRIADOS NA REGIÃO DO AGRESTE MERIDIONAL DO ESTADO DE PERNAMBUCO, BRASIL

Com o objetivo de se analisar os principais fatores de riscos associados à ocorrência do timpanismo espumoso em bovinos, foi realizado um estudo retrospectivo de 60 casos clínicos da enfermidade, diagnosticados em bovinos atendidos na Clínica de Bovinos, Campus Garanhuns da Universidade Federal Rural de Pernambuco, no período entre janeiro de 1989 a dezembro de 2007. Analisaram-se 60 fichas clínicas das quais foram resgatadas informações como alimentação, sistema de criação, época do ano, período de lactação, sexo e idade dos animais. Constatou-se que, dos 60 animais acometidos, 54 (90%) recebiam dietas com alto teor de concentrados e 41 (68,33%) possuíam a palma como um dos ingredientes alimentares. Para 48 (80%) animais, o sistema de criação verificado era de semi-intensivo a intensivo. A maioria dos animais acometidos era fêmea (57/60 – 95%); desses, 44 (84,08%) encontravam-se em lactação. A maior ocorrência (62%) dos casos de timpanismo espumoso foi registrada no período do verão. O fluido ruminal desses animais tinha o valor de pH que oscilava ente 7 e 8, a consistência era espumosa e havia comprometimento da fauna. Conclui-se que a associação de fatores como a oferta de dietas ricas em concentrados, durante o período de verão, para vacas nos dois primeiros trimestres de lactação, criadas num sistema semi-intensivo a intensivo de produção, devem ser considerados na etiopatogenia do timpanismo espumoso em bovinos na região do Agreste Meridional do Estado de Pernambuco – Brasil.

Ultrasonographic Diagnosis of Ileal Intussusception in Calf

Background: Intussusception, characterized by invagination of an intestinal segment into the lumen of the adjacent segment, is one of the main causes of intestinal obstruction in cattle, and occurs more frequently in calves. The diagnosis of the disease is based on the history, clinical examination, and complementary exams, which are a challenge in this species, especially in calves, in which transrectal palpation is limited. As it is a non-invasive, effective, and low-cost test, ultrasonography could be an important tool in the diagnosis of intestinal obstructions, in which time is essential for the prognosis. Therefore, the objective was to report a case of intussusception in a calf diagnosed by ultrasound.Case: A 4-month-old calf, weaned at 3 months and raised intensively, was treated at the Clínica de Bovinos de Garanhuns, campus of the Universidade Federal Rural de Pernambuco (CBG/UFRPE), with a history of apathy, anorexia, and dyschezia for 3 days. On physical examination, fever, moderate dehydration, tachycardia, tachypnea with polypnea, bilaterally bulging abdomen, sound of fluid on ballottement, ruminal and intestinal hypomotility, and melena were observed. The hematological findings revealed leukocytosis due to neutrophilia (degenerate neutrophils), hypoproteinemia, and hyperfibrinogenemia. The analysis of the ruminal fluid showed compromised microbiota and increased chloride content. The transabdominal ultrasonography demonstrated, in the right ventral region, hypermotile and full small bowel loops and an increase in the volume of the peritoneal fluid. In addition, there was a segment of the small intestine which, in cross-section, showed multiple concentric rings (“onion rings”, “target pattern”, or “bull’s eye”) and adherence to adjacent loops, compatible with intestinal obstruction due to intussusception. Due to the seriousness of the clinical condition and the ultrasound findings, the animal was euthanized and the necropsy revealed focal fibrinous peritonitis and intestinal obstruction due to intussusception in ileum intestinal segments.Discussion: Intussusception has previously been reported in calves, however this is the first report of ultrasound diagnosis of the disease in Brazil. Although the etiology is rarely confirmed, the age group and recent changes in diet (weaning) were predisposing factors. The history, clinical signs, and laboratory tests were similar to those described in cattle with intussusception, however they may be present in other gastrointestinal illnesses. Other authors have also reported that the nonspecificity of the signs and the impossibility of performing transrectal palpation made it difficult to diagnose intestinal obstruction in calves without the use of other diagnostic tools. As it is a non-invasive and accurate technique, ultrasound has been used in ruminants for diagnostic purposes, including intestinal obstructions. In the present case, the main findings are described as the presence of a lesion with the appearance of multiple concentric rings, hypermotile, dilated, and full intestinal loops. The pathological findings were compatible with the ultrasound images and similar to those described by other authors, confirming the diagnosis. The use of ultrasonography as a diagnostic tool in cattle should be expanded, aiming at the early determination of diagnosis and prognosis, to reduce producer costs and animal discomfort. In cases of intussusception, late diagnosis makes treatment unfeasible
