Introduction: Visceral leishmaniasis (VL) stands out as a zoonosis observed on four continents and also in urban expansion zones in several regions of Brazil. Methods: A cross-sectional epidemiological study of VL cases in children under 15 years of age in the period from 2007 to 2012. Clinical data were gathered from medical reports; meteorological data were obtained at the Meteorological Measurement Department of UFT. Environmental variables were divided into two periods, rainy and dry. Results: The study revealed no difference by gender (p=0.67) among the 821 patients. However, the most affected age group was between one and fi ve years of age (58.6%; p<0.01); the highest prevalence of the disease (99.03%; p<0.01) occurred in urban zones; and the most affected ethnic group (85.5%; p<0.01) was mixed race. The highest incidence coeffi cients in this population occurred in 2007 and 2008 (578.39/100,000 inhabitants; 18.5/100,000 inhabitants, respectively), whereas the highest lethality coeffi cients occurred in 2008 and 2011 (0.85/100 deaths). There was no signifi cant correlation between average rainfall and the number of VL cases. The correlation between temperature and number of VL cases was negative (r = -0.4039; p<0.01). Conclusions: In Araguaína, visceral leishmaniasis in children under 15 years is an urban-based endemic disease distributed across all districts of the city wherein temperature as an environmental factor, a higher prevalence in mixed race children between one and fi ve years of age, and a high incidence coeffi cient all strongly contribute to child mortality. © 2014 Sociedade Brasileira de Medicina Tropical.

Introduction: The prevalence of infection by Toxoplasma gondii and associated risk factors in pregnant women in Tocantins, Northern Brazil were assessed. Methods: Serological analysis was performed in 338 serum samples and an oral questionnaire was utilized to identify potential risk factors. Results: Anti-IgG antibodies against T. gondii were detected in 71% (240/338) of the pregnant women. Prior contact with cats and meat handling were found to be associated with T. gondii infection. Conclusions: A considerable percentage (29%) of women living in the Tocantins area remain susceptible to infection by the T. gondii protozoon, representing a serious public health risk. © 2015, Sociedade Brasileira de Medicina Tropical.

Crop-livestock integration is an alternative method of rehabilitating degraded pastures. The goal of the present study was to evaluate the initial responses of morphostructural characteristics of two different Urochloa brizantha cultivars grown in monocropping or intercropping systems over two agricultural years. U. brizantha cultivars Marandu and Piatã were grown as monocrops or intercropped with corn or sorghum. A randomized block experimental design with a triple factorial scheme, two additional treatments (2x2x2+2) and four replicates was used. The following factors were tested: two U. brizantha cultivars (Marandu or Piatã), two intercropping combinations (with corn or sorghum), and two agricultural years (2010/2011 and 2011/2012). An additional treatment included U. brizantha cultivars grown as monocrops. The morphogenic and structural characteristics and forage gross production rates were evaluated in the different cropping systems. Intercropping with grain crops had a negative effect on the initial productivity of U. brizantha, and areas with intercropping presented higher tiller density, lower rates of leaf emergence and elongation and lower forage gross production rates relative to the monocropping systems. However, intercropping is a viable alternative to conventional monocropping systems, which was indicated by the land equivalent ratio. Source

Case report of a female patient, 44 years-old, victim of cervical trauma in a traffic accident, who had painful cervical mass, associated with hoarseness and dysphagia three weeks after trauma. Additional tests identified the pseudoaneurysm of common carotid artery in zone II. We opted for treatment through the open conventional surgery with excellent immediate result. Control examination was performed seven months after surgery, and the results confirmed the therapeutic success. Source

This report describes the case of a patient with acute Chagas disease in Tocantins, Brazil, who was unaware of her pregnancy during benznidazole treatment. She presented with impaired cardiac function during the acute phase (pericarditis and incomplete right bundle-branch block) that resolved favorably after benznidazole therapy. Serological results also became negative, as determined by hemagglutination assays, enzyme-linked immunosorbent assays, and immunofl uorescence assays. The child was born without sequelae and showed no evidence of congenital Trypanosoma cruzi infection at birth or 24 days later. Source
