RESUMO
Tuberculosis (TB) is still considered a priority due to its high incidence rate in Brazil. In this context, we aimed to evaluate the flow of care between the municipalities of patients diagnosed with TB through notification forms of the Information System for Diseases and Notifications (SINAN) in a neglected region of Northern Brazil, Ilha do Marajó, state of Para. For this, we performed a descriptive, retrospective study on data obtained from the National Register of Health Establishments and SINAN from 2013 to 2018. We used Pearson's Chi-square and G Test with p-value < 0.05 for descriptive statistics and spatial analysis technique on flow network analysis. Of the 749 cases, 16.5% were notified in another municipality that was not the patient's residence. Regarding diagnostic methods, a positive bacterioscopy was adopted for 56% of the patients; culture was not performed for 82% of cases. Histopathological examination was not performed in 90% of the individuals. Rapid molecular test (RMT) was performed in only six (5%) cases. The region needs greater attention focused on diagnostic tests, suggesting that the introduction of RMT and culture by Ogawa-Kudoh could improve the region's health network to minimise patient displacement and thus avoid the increase in the transmission chain of TB.
RESUMO
INTRODUCTION: Cutaneous Leishmaniasis is a disease transmitted to men and animals by infected female phlebotomine sandflies and is considered a great environmental and public health problem in the Amazon region. Thus, the study aimed to analyze the spatial distribution of this disease in São Félix do Xingu, in the state of Pará, Brazil, and its relationship with epidemiological and environmental variables, in the period from 2012 to 2016. METHODOLOGY: The data used were from the Information System of the Pará State Secretariat of Health, the National Institute for Space Research and the Brazilian Institute of Geography and Statistics. The statistical and spatial analysis of the variables were done using non-parametric chi-square statistical test, kernel interpolation technique and the Bivariate Global Moran Index. RESULTS: The municipality had 183 confirmed cases, non-homogeneously distributed in 5 administrative districts. The individuals most affected were adult males with brown skin, an elementary level of education and rural area residents. In the case series, a direct relationship was observed between the increase of the number of cases and deforestation in the study area. The spatial analysis showed different types of land use and cover related to case clusters in the municipality. Additionally, there was a presence of cases in protected areas and a great epidemiological silence in indigenous lands. CONCLUSIONS: Thus, this disease is a large and complex public health problem in the municipality, related to social and environmental risk factors.

Tuberculosis (TB) is an infectious communicable disease, which despite global efforts, still needs special attention in regions with difficult access. This study aims to describe the spatial and epidemiological trends of TB incidences from 2013 to 2018 in Marajó Island, the Amazonian region, Pará, Brazil. We have obtained secondary data from the Brazilian TB databases and performed geospatial and statistical analyses on the data for new TB cases, relapses, and re-admissions. From 2013 to 2018, 749 new cases were reported, in which the diagnostics (culture) was not performed for 652 (87.2%) patient samples, the drug resistance test (DST) was performed for nine (1.2%) samples, and one (0.13%) was multidrug-resistant TB (MDR-TB). The rapid molecular testing (RMT) was performed on 40 (5.3%) patient samples, with results indicating that eight (20%) were susceptible to rifampicin and two (5%) were rifampicin resistant. Overall, the cure rate was 449 (66.7%), while relapses and re-admissions were 41 and 44, respectively. On the geospatial distribution, the municipality of Soure stands out with a high number of incidences, relapses, and re-admissions. Spatially, the eight MDR cases were randomly distributed. Our data highlight the urgent need for TB control measures in this region, by introducing the Xpert-Ultra® MTB/RIF (Cepheid, Sunnyvale, CA, USA) and Ogawa-Kudoh.
