Clinical electroencephalogram (EEG) evaluation is improved by the amplitude asymmetry index

Arq. neuropsiquiatr; 74 (7), 2016
ABSTRACT Cerebral hemispheres, although similar, are neither completely symmetrical in structure nor equivalent in function. EEG asymmetry studies have been directed more to frequency than to amplitude analysis. Objective Better definition of normal amplitude asymmetry values on the classical EEG frequ...

Temporal profile of intestinal tissue expression of intestinal fatty acid-binding protein in a rat model of necrotizing enterocolitis

Clinics; 71 (7), 2016
OBJECTIVES: Necrotizing enterocolitis is a severe multifactorial intestinal disorder that primarily affects preterm newborns, causing 20-40% mortality and morbidity. Intestinal fatty acid-binding protein has been reported to be a biomarker for the detection of intestinal injuries. Our aim was to assess i...

Are patients with lichen planus really prone to urolithiasis? Lichen planus and urolithiasis

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Purpose to investigate whether patients with lichen planus (LP) are really prone to urolithiasis or not. Patients and Methods We performed a prospective analysis of 40 patients diagnosed with lichen planus (LP) (group I), and 40 volunteers did not have LP before (group II). Participants were...

Nitric oxide and asymmetric dimethyl arginine (ADMA) levels in an experimental hydronephrotic kidney caused by unilateral partial ureteral obstruction

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Aim Our aim is to measure asymmetric dimethyl arginine and nitric oxide levels in rats with induced unilateral acute ureteral obstruction to research the effects on the kidney. Material and Methods The study included 21 adolescent (average age 6 weeks) Sprague-Dawley male rats weighing betwe...

Can intraurethral stimulation inhibit micturition reflex in normal female rats?

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Objective The study was designed to determine the effect of low frequency (2.5Hz) intraurethral electrical stimulation on bladder capacity and maximum voiding pressures. Materials and Methods The experiments were conducted in 15 virgin female Sprague-Dawley rats (220–250g). The animals...

The influence of distal colon irritation on the changes of cystometry parameters to esophagus and colon distentions

Int. braz. j. urol; 42 (3), 2016
ABSTRACT The co-occurrence of multiple pathologies in the pelvic viscera in the same patient, such as, irritable bowel syndrome and interstitial cystitis, indicates the complexity of viscero-visceral interactions and the necessity to study these interactions under multiple pathological conditions. In the...

Dipstick spot urine pH does not accurately represent 24 hour urine PH measured by an electrode

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Objectives To determine whether spot urine pH measured by dipstick is an accurate representation of 24 hours urine pH measured by an electrode. Materials and Methods We retrospectively reviewed urine pH results of patients who presented to the urology stone clinic. For each patient we record...

Evaluation of PCA3 and multiparametric MRI's: collective benefits before deciding initial prostate biopsy for patients with PSA level between 3-10ng/mL

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Objective To analyze the contribution of multiparametric MRI and PCA3 assay, pre- decision of initial biopsy in PSA level between 3-10 ng/mL patients with normal digital rectal examination(DRE). Materials and Methods PSA level 3-10 ng/mL ,patients, with normal DRE results and no previous pro...

Effect of ejaculation on serum prostate-specific antigen concentration

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Abstract Purpose:To evaluate the effect of ejaculation on serum prostate-specific antigen (PSA) concentrations in patients with lower urinary tract symptom (LUTS). Materials and Methods Our study includes 98 men (62 study and 36 control). After three days of sexual abstinence, blood samples ...

Auditory evoked potential P300 in adults: reference values

Einstein (Säo Paulo); 14 (2), 2016
ABSTRACT Objective To establish reference intervals for cognitive potential P300 latency using tone burst stimuli. Methods This study involved 28 participants aged between 18 and 59 years. P300 recordings were performed using a two-channel device (Masbe, Contronic). Electrode placement was as follows...
