    Aspects related to the epidemiology of Diptera belonging to genus Chrysomya were studied in order to determine predisposing factors for their occurrence in commercial laying hens farms from the state of Minas Gerais, Brazil. An observational, analytical and sectional survey was conducted to verify the main epidemiological determinants of infestations by Chrysomya spp. Forty-three farms were visited in 2012 and these 13 (30,23%) were infested by Chrysomya putoria, 4 (9,30%) by Chrysomya megacephala and 2 (4,65%) by Chrysomya albiceps and in 2 farms (4,65%) was not possible to identify the species of Chrysomya. The epidemiological determinants for the occurrence of infestations by Chrysomya spp. were investigated using multiple logistic regression models. Housing clustering type and its conditions were important factors involved in epidemiology of these species (OR=5.05, 95% CI = 2.66 to 9.58, p = 0.000). It was also observed that the increase of the humidity of manure leads to increase chances of infestations (OR = 1.81, 95% CI = 1.36 to 2.40, p = 0.000). The presence of the beetle “lesser mealworm” (Alphitobius diaperinus) (OR = 0.15, 95% CI = 0.067 to 0.36, p = 0.000) was characterized as a protective factor against infestations, probably due to predation behavior of the beetle. Some regions of the state were characterized as lower risk areas for Chrysomya spp. infestation as compared to other regions. Management measures, such as constant monitoring of water leaks on manure, adequate composting of dead poultry and periodic removal of manure could assist in decreasing the presence of Chrysomya spp. inside the laying houses

    Aspects related to the epidemiology of Megninia ginglymura were studied, in order to determine predisposing factors for the ocurrence in layer chicken houses of commercial farms in the State of Minas Gerais, Brazil. An observational, cross-sectional, analytical survey was conducted for identifying major risks or protection factors for infestations. Four hundred thirty-one houses located in forty-three farms were visited in 2012. Regarding the farms, 17 (39.53%) had chickens infested by M. ginglymura and 1 (2.32%) presented Megninia cubitalis. The epidemiological aspects of the occurrence of M. ginglymura were investigated using multiple logistic regression models. The chicken house organization was an important protection factor involved in the occurrence of M. ginglymura (odds ratio [OR] = 0.85). The presence of subsistence breedings of poultry within the premises or at the proximity of a farm was characterized as a risk factor for the occurrence of infestations (OR = 3.92). The use of mineral oil (OR = 0.16) was considered protective against new infestations. Some regions of the state were characterized by a higher risk for mite infestation than others

    Tratamento endovascular da hemorragia digestiva aguda por volumoso pseudoaneurisma esplênico: relato de caso e revisão da literatura

    Full text link
    Resumo O pseudoaneurisma da artéria esplênica é uma entidade rara, com pouco mais de 150 casos descritos na literatura. A pancreatite é a etiologia mais comum, seguida do trauma. Em contraposição ao aneurisma verdadeiro, esse pseudoaneurisma é frequentemente sintomático, com risco de ruptura de 47% e mortalidade de 90%, quando não tratado. Descrevemos o caso de uma paciente de 48 anos que apresentou hemorragia gastrointestinal associada a pancreatite crônica agudizada. Durante investigação, a endoscopia evidenciou sinais de sangramento recente, e a angiorressonância de abdome observou volumoso pseudoaneurisma da artéria esplênica. Foi submetida a tratamento endovascular com embolização com micromolas, não apresentando novos episódios de sangramento. Atualmente, o tratamento endovascular é efetivo com baixa morbimortalidade e taxas de sucesso de 79-100%, sendo uma técnica viável para pacientes com processo inflamatório abdominal em franca atividade. Realizamos uma revisão das técnicas endovasculares e agentes embolizantes usados para o tratamento dessa patologia

    Synanthropic diptera affecting layer poultry farms: a review

    Full text link
    ABSTRACT: The poultry farm of posture is an economic activity of great relevance to Brazil. Health aspects of flocks of laying chickens, such as the occurrence of infestations by parasites and poultry pests, influence significantly the productivity indicators. In this context, the control of synanthropic diptera is one of the challenges of the poultry farmers and professionals of this area. In Brazil, the control of flies in poultry environments is based mainly on the use of pesticides, while other alternatives are less frequent. Among the flies’ species most regularly found in poultry farms are the Musca domestica, Chrysomya spp., Fannia spp., and others. This review aims at compiling the literature on the occurrence, impact on poultry systems, biology, epidemiology and control of the species of synanthropic flies considered important for the Brazilian poultry industry

    Endovascular treatment of acute gastrointestinal bleeding from a large splenic artery pseudoaneurysm: case report and literature review

    <p></p><p>Abstract Pseudoaneurysm of the splenic artery is a rare entity, with little more than 150 cases described in the literature. Pancreatitis is the most common etiology, followed by trauma. In contrast with true aneurysms, pseudoaneurysms are frequently symptomatic, with a 47% risk of rupture and 90% mortality if left untreated. We describe the case of a 48-year-old female patient who suffered a gastrointestinal hemorrhage associated with acute-on-chronic pancreatitis. During workup, endoscopy revealed signs of recent bleeding and magnetic resonance angiography of the abdomen showed a large pseudoaneurysm of the splenic artery. The patient underwent endovascular treatment with microcoil embolization and no further bleeding episodes occurred. Endovascular treatment is now an effective option with low morbidity and mortality and success rates in the range of 79-100%, making it a viable technique for patients with active abdominal inflammation. We conducted a review of endovascular techniques and embolization agents used to treat this pathology.</p><p></p

    Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

    Full text link
    The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications
