The research quantified the probable monthly, quarterly, and annual precipitation height and analyzed the synoptic systems intervening over time for an important grain producing region located in the Brazilian legal Amazon. Through stochastic and geostatistical analysis, the study estimated the probable height of rain, showed its seasonality, its spatial behavior and the months with extreme rainfall. For stochastic modelling of rain, the gamma distribution, the maximum likelihood method was used to estimate the parameters, and the Kolmogorov-Smirnov test as an adhesion test. For spatialization of rain data, geostatistical modelling was performed using ordinary kriging as an interpolation method. We conclude that: there are two well-defined seasons in the middle north region of Mato Grosso (MNMT), a rainy one between October and April and a dry one between May and September; the months of April and October can be considered as months of transition between the two seasons; the months with the highest probable rainfall are December, January and February; the probable annual precipitation (PPA) in the MNMT region has an average value of 1622 mm, with a minimum of 1341 and a maximum of 1955 mm; the spatial distribution of rain is influenced by latitude and there is a tendency for the total to increase in the SE-NW direction. Finally, spatial analysis shows that the highest rainfall occurs in the north and northwest of the study area. The smallest, however, occur in the south and southeast of the area, mainly in the municipality of Nova Ubiratã. [ABSTRACT FROM AUTHOR]

Visceral Leishmaniasis (VL) is considered by the WHO as one of the most neglected diseases in the world. Therefore, we aim to describe a case of VL and its treatment in the city of Porto Franco, Maranhão, Brazil. The suspicion of VL in young people arises from the initiative of the person in charge of performing an ultrasound of the abdomen and complementary exams that found splenomegaly. The results were confirmed by the Leishmania reagent test, Donovani-IGM antibody. Treatment consisted of daily administration of three ampoules of Glucantime/20 days. Therefore, prior diagnosis, medical follow-up and adequate treatment are necessary for the non-clinical evolution of the disease. [ABSTRACT FROM AUTHOR]
