Significado da presença de esquizócitos no sangue periférico de gestantes com pré-eclâmpsia

PURPOSE: to evaluate the significance of schizocytes presence in peripheral blood smear of pregnant women with pre-eclampsia, identifying and correlating them with other markers of hemolysis and of the disease severity. METHODS: Seventh six glass slides of peripheral blood smear of pregnant women with pre-eclampsia have been evaluated. After the smear, the slides have been stained with Leishman's dye and stored till they were examined with a Leica, model DLMB microscope, provided with the Qwin Lite 2.5 software that made it possible to record the images of selected fields in CD-ROM. Ten fields with approximately 100 erythrocytes were counted in each glass slide. Schizocytes (irregular fragment or helmet-shaped, bite-shaped or triangular) were considered as present, when their percentage was equal or higher than 0.2%, their presence being correlated with other hemolysis markers (hemoglobin, total bilirubin, lactic desidrogenasis and reticulocytes), pre-eclampsia markers (proteinuria and platelet number). The Statistical Package in Social Science for Windows (SPSS), 10.0 version has been used for statistical analysis, at p<0.05. RESULTS: schizocytes have been present in 31.6% of the pregnant women with pre-eclampsia. In most (75%) of the blood smears there have been three or four schizocytes. There has been no correlation between schizocyte presence and any other hemolysis marker, any pre-eclampsia marker or disease severity. CONCLUSIONS: schizocytes have been identified in a small number and in less than a third of the pregnant women with pre-eclampsia. There has been no correlation with other hemolysis marker parameters or with the disease severity. This way, the presence of schizocytes is not a marker of the clinical evolution of pre-eclampsia.

Modelagem em escala regional da erosão relacionada com a evolução da cobertura do solo: Um estudo de caso no sudeste do Brasil

Accelerated soil erosion is, at present, one of the most widespread environmental problems in the world. Geographic Information Systems (GIS) have become an essential tool in soil erosion studies and consequently in the development of appropriate soil conservation strategies. The objective of this paper was to assess the degree of soil erosion associated with land cover dynamics through GIS analysis and to validate the modeling with indicators of soil erosion. Universal Soil Loss Equation (USLE) model, GIS technology and ground-truth dataset (erosion indicators) were employed to elaborate the soil loss maps for four dates at Sorocaba Municipality (SP, Brazil). It was verified that, although the predicted soil loss rate is normally small along the study area, such rate is significantly greater than the soil formation rate. This shows a non-sustainable situation of soil and land cover management. Unplanned urban expansion seems be the main driving force that acts in increasing the erosion risk/occurrence along the study area.

Escala de ansiedade odontológica: Reprodutibilidade das respostas dadas em entrevistas telefônicas e pessoais

Objective: To estimate the intra-examiner reproducibility of the Dental Anxiety Scale (DAS) when applied by phone and personal interviews and to evaluate the association between the level of anxiety and the factors of interest. Method: The participants were 50 individuals (n=38 females) with mean age of 23.9±8.9 years, living in the city of Araraquara, SP, Brazil. The volunteers answered the DAS by means of two phone interviews with one-week interval between them. After 30 days, the DAS was applied to the same participants by means of personal interviews at two moments with one-week interval between them. Intra-examiner reproducibility was determined using Kappa (K) statistics by point and by confidence interval. Results: The intra-examiner agreement for the level of anxiety was 0.82 (0.75-0.90) for the phone interview and 0.69 (0.60-0.79) for the personal interview. Two of the DAS questions presented statistically significant difference in the intra-examiner reproducibility, with better agreement for the answers given by the participants during phone calls. The prevalence of dental anxiety in the sample was 92.0%, in such a way that 70.0%, 18.0% and 4.0% of them presented low, moderate and exacerbated anxiety. Conclusion: The classification of the individuals according to the anxiety level performed by means of phone and personal interviews presented statistically similar agreement. However, there was better agreement with phone calls for the questions referring to anxiety in the dental office's waiting room and during preparation of the motor for use in the dental treatment.
