[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: It is known that chronic kidney disease (CKD) is continuously increasing all over the world, but the available numbers of affected subjects are mostly collected from renal replacement therapy services and they correspond to individuals with end-stage renal disease. The aim of the present study was to diagnose CKD in its earliest stages in the general population based on detection of proteinuria.METHODS: In public prevention campaigns, from 2005 to 2010, 38 721 inhabitants were evaluated in the state of Sao Paulo (Brazil). Screening procedures included a dipstick test, blood pressure measurement and application of a medical questionnaire.RESULTS: In the whole population, urine samples of 37 771 individuals (mean age: 44.59 + 21.70, 55.74% females) were evaluated, 7.3% presented proteinuria (1+ or more) in the screening test and 85.5% of them had no previous knowledge of this urinary abnormality. Those individuals were referred for further clinical evaluation in order to confirm the detected alterations. Considering being diabetic and/or hypertensive as important risk factors for CKD, it was observed that they corresponded to 9.7 and 28.4% of the population screened for proteinuria, respectively. Newly detected cases of possible CKD, diabetes and hypertension corresponded to 6.2, 0.3 and 6.5%, respectively.CONCLUSIONS: This initiative provided information on proteinuria and possible cases of CKD based on a large sampling of the Brazilian population. Proteinuria was detected in 7.3% of these individuals, and such prevalence is similar to that previously described in developed countries.
[Show abstract][Hide abstract] ABSTRACT: Epilepsy is the most common acquired chronic neurological disorder; each year about 1 in a 1000 patients with chronic epilepsy die suddenly, unexpectedly, and without explanation, even with postmortem examination (SUDEP). Seizure incidence is approximately 10% in patients with chronic renal failure and hemodialysis-associated seizure has been considered to be a common complication of people on hemodialysis treatment. Considering this, we evaluated the incidence of seizures in 189 patients under dialytic treatment.

[Show abstract][Hide abstract] ABSTRACT: Of the many risk factors suggested for sudden unexpected death in epilepsy (SUDEP), higher frequency of seizures is a very consistent issue. Following this reasoning, it has been established that hemodialysis-associated seizure is a complication of dialysis procedure. Based on these facts, this study investigated a possible association between cardiovascular abnormalities and SUDEP among patients with chronic renal insufficiency in regular hemodialysis program. For that, a retrospective medical history of 209 patients was reviewed to investigate the occurrence of convulsive seizures and EKG abnormalities during dialytic program. Three patients presented generalized tonic-clonic seizures, one had partial seizure with secondary generalization, and one presented unclassified seizure. Any EKG abnormalities and SUDEP event were found in all patients evaluated. In conclusion, the present findings demonstrated uncommon the occurrence of seizures and also SUDEP. Probably, the main justification to not allow us to demonstrated a direct relation between SUDEP and cardiovascular diseases in hemodialysis are the reduced number of cases examined.

[Show abstract][Hide abstract] ABSTRACT: Hemodialysis-associated seizure is a complication of hemodialysis. This report describes the occurrence of seizures in patients with end stage renal disease on dialysis therapy at the Nephrology Institute of Mogi das Cruzes, São Paulo State, Brazil. A retrospective medical history of 189 patients was reviewed to investigate the occurrence of convulsive seizures during dialytic program. Seven patients with history of seizures were selected but five of them were included in our study. Three patients presented generalized tonic-clonic seizures, one had partial seizure with secondary generalization, and one presented unclassified seizure. Three patients presented seizure just during the dialysis (unique seizure) and one of them presented convulsive status epilepticus. The two other patients had already presented seizures prior the beginning of dialysis. We conclude that seizures in renal failure could be considered as occasional events that do not usually become chronic.
