M. C. de Albuquerque Neto, Leslie Clifford Noronha Araujo, Thome Decio Pinheiro Barros Junior, Joao Luiz Amaro, Flavia Cristina Morone Pinto, Fabio de Oliveira Vilar, Salvador Vilar Correia Lima
Open Journal of Urology (OJU) , 2017, DOI: 10.4236/oju.2017.73008
Abstract: Aim: To determine whether bladder functions deteriorate with age. Methods: Data contained in electronic medical record (INFOMED?) were used in this institutional retrospective review. Analysis was done on the urodynamic studies in women over 18 years old conducted between May 2011 and November 2015. Patients with previous history of pelvic surgery or radiotherapy, neurological disease, vaginal prolapse greater than grade I, congenital urogenital malformations, urinary obstructive disease, diabetes, or the use of any medication that could interfere with bladder function were excluded from the analysis. The urodynamic parameters analyzed were the Maximum Cystometric Capacity (MCC), Voiding Volume (VV), Maximum Flow (Qmax), Bladder Compliance (BC), Detrusor Pressure at Maximum Flow (PdetQmax), Bladder Contractility Index (BCI), Bladder Voiding Efficiency (BVE) and Post-Void Residual Urine Volume (PVR). Patients were further stratified in five groups according to age (A—18 to 40; B—41 to 50; C—51 to 60; D—61 to 70; E—over 70 years old). Results: Out of 3103 urodynamic studies analyzed, 719 were eligible for the study. The average age of patients was 49.3 (+13.2) years old and in all evaluated parameters, statistically significant correlation between age and decline of bladder function was obtained (p < 0.05). Moreover, mathematical equations were presented to estimate the parameters values in relation to age. Conclusions: This study showed a decline in bladder storage function (reduction in MCC and BC) and in bladder emptying function (reduction in Qmax, PdetQmax, VV, BCI and BVE with an increase in PVR) with age.

Abstract: introduction: metabolic investigation in patients with urinary lithiasis is very important for preventing recurrence of disease. the objective of this work was to diagnose and to determine the prevalence of metabolic disorders, to assess the quality of the water consumed and volume of diuresis as potential risk factors for this pathology. patients and methods: we studied 182 patients older than 12 years. we included patients with history and/or imaging tests confirming at least 2 stones, with creatinine clearance > 60 ml/min and negative urine culture. the protocol consisted in the collection of 2, 24-hour urine samples, for dosing ca, p, uric acid, na, k, mg, ox and ci, glycemia and serum levels of ca, p, uric acid, na, k, cl, mg, u and cr, urinary ph and urinary acidification test. results: 158 patients fulfilled the inclusion criteria. among these, 151 (95.5%) presented metabolic changes, with 94 (62.2%) presenting isolated metabolic change and 57 (37.8%) had mixed changes. the main disorders detected were hypercalciuria (74%), hypocitraturia (37.3%), hyperoxaluria (24.1%), hypomagnesuria (21%), hyperuricosuria (20.2%), primary hyperparathyroidism (1.8%) secondary hyperparathyroidism (0.6%) and renal tubular acidosis (0.6). conclusion: metabolic change was diagnosed in 95.5% of patients. these results warrant the metabolic study and follow-up in patients with recurrent lithiasis in order to decrease the recurrence rate through specific treatments, modification in alimentary and behavioral habits.
An Application of Paraconsistent Annotated Logic for Design Software Testing Strategies  [PDF]
Marcos Ribeiro do Nascimento, Luiz Alberto Vieira Dias, Joao Inacio Da Silva Filho
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.75034
Abstract: Nowadays, application model systems for decision-making based on non-classical logic such as Paraconsistent Logic are used successfully in the treatment of uncertainties. The method presented in this paper is based on the fundamental concepts of Paraconsistent Annotated Logic with annotation of 2 values (PAL2v). In this study, two algorithms based on PAL2v are presented gradually, to extract the effects of the contradiction in signals of information from a database of uncertain knowledge. The Paraconsistent Extractors Algorithms of Contradiction Effect-Para Extrctr is applied to filters of networks of analyses (PANets) of signal information, where uncertain and contradictory signals may be found. Software test case scenarios are subordinated to an application model of Paraconsistent decision-making, which provides an analysis using Paraconsistent Logic in the treatment of uncertainties for design software testing strategies. This quality-quantity criterion to evaluate the software product quality is based on the characteristics of software testability analysis. The Para consistent reasoning application model system presented in this case study, reveals itself to be more efficient than the traditional methods because it has the potential to offer an appropriate treatment to different originally contradicting source information.

Abstract: objectives: the aim of this study was to evaluate the histopathological and immunohistochemical alterations induced by detrusor instability in the bladder of rabbits submitted to partial bladder outlet obstruction. materials and methods: thirty male norfolk rabbits were divided into 2 groups, a clinical control and a group with detrusor instability. urine culture, cystometric study, histopathological and immunohistochemical analysis were performed in all animals prior to surgery (m1) and 4 weeks after-surgery (m2). results: partial obstruction (g2) resulted in a 2.5 fold increment (p < 0.05) in bladder weight when compared to control (g1). four weeks after surgery, 93% of animals in g2 developed cystitis. partial obstruction resulted in detrusor instability at m2 and bladder capacity was significantly increased (p < 0.05) from m1 to m2. the incidence of mild to moderate mucosal and adventitious fibrosis at m2 was higher in g2 (p < 0.05) when compared to g1. inflammatory reaction at m2 was statistically higher (p < 0.05) in g2. there was no difference in muscular hypertrophy between m1 and m2 in g1. however, 67% of g2 bladders showed a moderate to intense muscular hypertrophy at m2. hyperplasia of the epithelium was also increased in g2 when m1 and m2 were compared (p < 0.05). conclusion: detrusor instability induced by partial bladder outlet obstruction caused significant histopathological and immunohistochemical alterations in the bladder of rabbits.

Abstract: objective: we evaluated clinical characteristics of primary vesicoureteral reflux (vur) in infants in a 30-year period in brazil with special reference to the relation of renal parenchymal damage to urinary tract infection and gender. materials and methods: from 1975 through 2005, 417 girls (81.6%) and 94 boys (18.4%) with all grades of reflux were retrospectively reviewed. patients were categorized by the worst grade of reflux, maintained on antibiotic prophylaxis and underwent yearly voiding cystourethrography until the reflux was resolved. vur was considered resolved when a follow-up cystogram demonstrated no reflux. surgical correction was recommended for those who fail medical therapy, severe renal scarring or persistent vur. results: grades i to v vur resolved in 87.5%, 77.6%, 52.8%, 12.2% and 4.3%, respectively. renal scars were present at presentation in 98 patients (19.2%). neither gender nor bilaterality versus unilaterality was a helpful predictor of resolution. the significant difference was found among the curves using the log rank (p < 0.001) or wilcoxon (p < 0.001) test. conclusion: despite the current use of screening prenatal ultrasound, many infants are still diagnosed as having vesicoureteral reflux only after the occurrence of urinary tract infection in our country. scarring may be associated to any reflux grade and it may be initially diagnosed at any age but half of the scars are noted with higher grades of reflux (iv and v). the incidence of reflux related morbidity in children has significantly diminished over the last three decades.
