Two methods of preparation of urine for cytology were compared retrospectively. In method 1 cells in the urine were fixed after the preparation of the smear; in method 2 the cells were fixed before smear preparation. Urine cytology reports were correlated with subsequent histological analysis. The specificities of urine cytology using both methods were high (99%). The sensitivity using method 1...

AIM To analyse the effect of mechanical bowel preparation vs no mechanical bowel preparation on outcome in patients undergoing elective colorectal surgery. METHODS Meta-analysis of randomised controlled trials and observational studies comparing adult patients receiving mechanical bowel preparation with those receiving no mechanical bowel preparation, subdivided into those receiving a single ...

BACKGROUND AND AIM Adequate bowel preparation is important for safe and effective colonoscopy. Quality indicators (QI) for colonoscopy include achieving at least 95% completion rate and an adenoma detection rate (ADR) of at least 25% in average-risk men and 15% in average-risk women aged over 50. Our aim was to investigate the impact of bowel preparation on ADR and colonoscopy completion rates....

BACKGROUND & AIMS A number of factors have been identified that influence the yield of screening colonoscopy. The perceived tolerability of bowel preparation has not been studied as a predictor of quality outcomes in colonoscopy. We aimed to characterize the association between patient-perceived tolerability of bowel preparation and polyp detection during colonoscopy. METHODS We performed a c...

Adopting a mixed response strategy in competitive situations can prevent opponents from exploiting predictable play. What drives stochastic action selection is unclear given that choice patterns suggest that, on average, players are indifferent to available options during mixed-strategy equilibria. To gain insight into this stochastic selection process, we examined how motor preparation was all...

BACKGROUND Inadequate colonoscopy bowel preparation can lead to increased procedural time, decreased diagnostic yield, and an increased complication rate. Little is known about which patient characteristics may predict poor bowel preparation for routine, average-risk colonoscopy evaluation. METHODS 300 consecutive patients who underwent routine, average risk outpatient screening colonoscopy d...

In everyday behavior, two of the most common visually guided actions-eye and hand movements-can be performed independently, but are often synergistically coupled. In this study, we examine whether the same visual representation is used for different stages of saccades and pointing, namely movement preparation and execution, and whether this usage is consistent between independent and naturalist...

Background: The touch preparation technique is an accurate and rapid method, and when used as intraoperative consultation examination technique it preserves a good amount of tissue for paraffin embedded sections. This study aimed at examining the accuracy of the touch preparation technique by comparing its diagnosis with that of final pathological diagnosis made by microscopic examinations. ...

sena-graph syrup has recently been formulated by an iranian pharmaceutical company for being used in bowel evacuation before radiography, colonoscopy and surgery. this study compares the efficacy, adverse effects and patient compliance of two bowel preparation regimens with castor oil and sena-graph syrup in of outpatients for intravenous urography (ivu). one hundred and fourteen consecutive ou...

BACKGROUND Mechanical bowel preparation is used routinely before colorectal surgery, but some randomized clinical trials have suggested that it is of no benefit. This study assesses whether such bowel preparation may safely be omitted before elective colorectal surgery. METHODS A search of the literature was performed; the inclusion criteria were randomized clinical trials comparing bowel pre...
