Materials and Methods: A total of 298 toilet trained children with primary vesicoureteral reflux underwent urodynamic evaluation. Urodynamic parameters were reviewed and correlated with age, gender, presence of lower urinary tract symptoms and reflux severity.

Results: Symptomatic lower urinary tract symptoms were MK 2206 present in 111

children (37.2%, group 1). Children with lower urinary tract symptoms had significantly decreased severity of vesicoureteral reflux compared to children without these symptoms (187 patients, group 2). The majority of the patients had normal early bladder compliance regardless of presence of lower urinary tract symptoms or reflux grade. On the other hand, decreased late bladder compliance was more common in group 1 vs group 2. Ratio of cystometric bladder capacity to expected bladder capacity was higher in group 2. Detrusor overactivity was observed in 28.5% of LY3009104 ic50 the children, and the incidence was significantly higher in group 1 vs group 2, and in mild vs moderate or severe reflux. Dysfunctional voiding from bladder sphincter dyscoordination was seen in 32% of children 2.5 to 4 years old with vesicoureteral reflux and lower urinary tract symptoms, compared to 8% in children 5 to 16 years old.

Conclusions: The presence of lower urinary tract symptoms in children with

vesicoureteral reflux correlated well with some urodynamic findings suggestive of overactive bladder and negatively correlated with reflux severity. In contrast, dysfunctional voiding was more common in younger children with reflux and lower urinary tract this website symptoms. These findings suggest that treatment of voiding dysfunction should be directed

toward the specific type of abnormality in children with vesicoureteral reflux.”
“The ‘thermal grill illusion’ refers to paradoxical sensations of heat and pain, resulting from simultaneous application of interlaced warm and cold stimuli to the skin. It provides an interesting model of integrative mechanisms in the nervous system, supposed to be relevant in explaining the hypersensitivity found in chronic pain of unclear etiology. The aim of this study is to investigate the perceptual qualities elicited by a reconstruction of the original grill stimulator and to compare these qualities with those elicited by a single temperature thermode of identical dimensions. Healthy participants performed these comparisons by choosing adjectives describing the perceived sensory qualities. We hypothesized that the thermal grill would be perceived as different from a single temperature hot stimulus near pain threshold because of varying sensory qualities. Moreover, the qualities elicited by the grill were expected to be different from the qualities elicited by its single component temperatures. The thermal grill elicited a complex percept, which was distinguished almost perfect from a hot stimulus.
