BACKGROUND: Epilepsy affects adults at productive age and interferes with their ability to work. However, the granting of social security benefits to these patients has not received sufficient attention. This article aims to provide a profile of individuals with a previous diagnosis of epilepsy that file claims for social security benefits and a profile of the medical advisory decisions that support the concession of these benefits. PARTICIPANTS: A sample of thirty individuals with illness-related problems due to epilepsy was selected from the claimants that receive Social Security Incapacity/Sickness benefits. METHODS: An exploratory data analysis of the 188 Social Security medical files of the thirty claimants was performed using the clinical and epidemiological information and the medical advisory criteria. RESULTS: The mean age of the claimants was 39 years and most of them were males in jobs that do not require a lot of schooling. The first claim was filed within an average of four years of employment. On average, each worker files a claim every three months, which entitles him/her to receive incapacity/sickness benefits for seventeen months. The frequency of seizures and the medications used by the claimants were registered in 60% of the medical files. In addition, the description of the physical and neurological exam was incomplete in 50% of the files. Furthermore, 60% of the files did not include the argument or the clinical evidence that was used to justify the concession of a benefit. CONCLUSION: The medical advisory decisions on epileptic workers tend to be inconsistent, overly lenient and generally lacking in clinical evidence. The disparities among the granted benefits indicate the need for the National Social Security System to review and draft specific guidelines for epilepsy. © 2013 - IOS Press and the authors.

A long-term study (monthly sampling, 1992 to 2007) was conducted in the surf zone of Cassino Beach, Southern Brazil, in order to detect possible natural and/or anthropogenic disturbances. Surface water temperature (6-29°C) was the only parameter with predictable seasonal variation; salinity (14-38) was inversely related to rainfall (3.1-485.2 mm month -1) and low values followed extreme precipitation periods in 1997/1998 and 2002/2003 (El Niño years). Asterionellopsis glacialis and chlorophyll a presented high concentrations and peak frequency until 1998, when an intense mud deposition occurred with concomitant extreme rainfall. It affected the surf zone and beach, changing the hydrology and dissolved inorganic nutrient availability. Six phytoplankton species groups were recognized with distinct responses to this mud deposition. We conclude that large-scale climatic changes, like El Niño Southern Oscillation, in conjunction with human activities significantly altered the phytoplankton ecology of the highly dynamic Cassino Beach surf zone. © Coastal and Estuarine Research Federation 2009.

Movement understanding frequently requires further information and knowledge than what can be obtained from bare spatio-temporal traces. Despite recent progress in trajectory data management, there is still a gap between the spatio-temporal aspects and the semantics involved. This gap hinders trajectory analysis benefiting from growing collections of linked data, with well-defined and widely agreed semantics, already available on the Web. This article introduces Baquara, an ontology with rich constructs, associated with a system architecture and an approach to narrow this gap. The Baquara ontology functions as a conceptual framework for semantic enrichment of movement data with annotations based on linked data. The proposed architecture and approach reveal new possibilities for trajectory analysis, using database management systems and triple stores extended with spatial data and operators. The viability of the proposal and the expressiveness of the Baquara ontology and enabled queries are investigated in a case study using real sets of trajectories and linked data. © Springer-Verlag 2013.

The current work describes the use of multidimensional Euclidean geometric distance (EGD) and Bayesian methods to characterize and classify the sky and cloud patterns present in image pixels. From specific images and using visualization tools, it was noticed that sky and cloud patterns occupy a typical locus on the red-green-blue (RGB) color space. These two patterns were linearly distributed parallel to the RGB cube's main diagonal at distinct distances. A characterization of the cloud and sky patterns EGD was done by supervision to eliminate errors due to outlier patterns in the analysis. The exploratory data analysis of EGD for sky and cloud patterns showed a Gaussian distribution, allowing generalizations based on the central limit theorem. An intensity scale of brightness is proposed from the Euclidean geometric projection (EGP) on the RGB cube's main diagonal. An EGD-based classification method was adapted to be properly compared with existing ones found in related literature, because they restrict the examined color-space domain. Elimination of this limitation was considered a sufficient criterion for a classification system that has resource restrictions. The EGD-adapted results showed a correlation of 97.9% for clouds and 98.4% for sky when compared to established classification methods. It was also observed that EGD was able to classify cloud and sky patterns invariant to their brightness attributes and with reduced variability because of the sun zenith angle changes. In addition, it was observed that Mie scattering could be noticed and eliminated (together with the reflector's dust) as an outlier during the analysis. Although Mie scattering could be classified with additional analysis, this is left as a suggestion for future work. © 2010 American Meteorological Society. Source

Background and Purpose: Renal cysts are the most common form of renal mass with a prevalence of 35% in people older than 50 years. Several techniques are used to manage symptomatics cysts, from sclerotherapy to open surgery. We present a safe and minimally invasive therapeutic alternative: Percutaneous endocystolysis (PE). Patients and Methods: Between 1995 and 2008, 32 patients were treated for large symptomatic Bosniak type I and II renal cysts with the PE technique. Percutaneous access was obtained by direct puncture guided by fluoroscopy or ultrasonography, percutaneous dilation, and placement of a 28F Amplatz sheath; then a 26F resectoscope with a rollerball electrode was introduced into the interior of the cyst and the whole internal surface was inspected and cauterized. After cauterization, a 20F Foley catheter was placed inside the cyst. Patients were discharged the next day, and the catheter was removed in the outpatient facility after 7 to 10 postoperative days. The variables of age, cyst volume, operative time, and length of hospital stay were statistically analyzed using the Pearson linear correlation coefficient. Results: Clinical follow-up ranged from 4 to 162 months (mean 76 mos). Percutaneous access to the cyst was obtained by blind puncture in 7 (21.8%) patients, aided by fluoroscopy in 12 (37.5%) patients, and guided by ultrasonography in 13 (40.7%) patients. Clinical improvement was observed in all patients with a success rate of 100%. The length of hospital stay was 21.7 ± 8.5 hours (range 9-48 h). The operative time was 41.8 ± 19.7 minutes (range 12-94 min). There was a low complication rate associated with the transparenchymatous PE procedure. Conclusion: PE is a safe, minimally invasive, and effective technique for the management of large symptomatic renal cysts and is associated with high success rates and low complication rates in long-term follow-up. © 2010, Mary Ann Liebert, Inc.
