Purpose: To determine whether listening to music during cystoscopy decreases anxiety, pain, and dissatisfaction among patients and results in a more comfortable and better-tolerated procedure. Materials and Methods: Seventy male patients who underwent rigid cystoscopy between May 2011 and December 2011 were randomized into the following: no music (Group I, n = 35) or classical music during procedure (Group II, n = 35). Before cystoscopy, lidocaine gel was instilled in the urethra, and both groups viewed their procedures on a video monitor. Anxiety levels were quantified according to the State-Trait Anxiety Inventory. A visual analog scale (0-10) was used for a self-assessment of satisfaction, discomfort, and willingness among patients to repeat the cystoscopy. Results: Demographic characteristics, mean age, procedure duration, and procedure indications were statistically similar between the two groups. The mean anxiety level and mean pain score of Group II were significantly lower than those of Group I ( p < 0.001 for both). Group II also carried a significant greater mean satisfaction score compared with Group I ( p < 0.001). Statistically significant differences were detected between groups in the postprocedural pulse rate and the systolic blood pressure ( p = 0.012 and p = 0.008, respectively), whereas preprocedure pulse rate and systolic blood pressure were similar. Conclusions: Listening to music during rigid cystoscopy significantly reduces feelings of pain, discomfort, and dissatisfaction. Music can serve as a simple, inexpensive, and effective adjunct to sedation during cystoscopy. We recommend the application of music during rigid cystoscopy for clinical use.

BackgroundThe purpose of this study was to investigate the association between the ionotropic and glutamate receptors, N-methyl D-asparate 2A (GRIN2A) and 2B (GRIN2B), and the metabotropic glutamate receptor mGluR7 (GRM7) gene polymorphisms and attention-deficit hyperactivity disorder (ADHD) in Korean population.MethodsWe conducted a case–control analysis of 202 ADHD subjects and 159 controls, performed a transmission disequilibrium test (TDT) on 149 trios, and compared scores from the continuous performance test (CPT), the Children’s Depression Inventory (CDI), and the State-Trait Anxiety Inventory for Children (STAIC) according to the genotype of the glutamate receptor genes.ResultsThere were no significant differences in the genotype or allele frequencies of the GRIN2A rs8049651, GRIN2B rs2284411, or GRM7 rs37952452 polymorphisms between the ADHD and control groups. For 148 ADHD trios, the TDT analysis also showed no preferential transmission of the GRIN2A rs8049651 or GRIN2B rs2284411 polymorphisms. However, the TDT analysis of the GRM7 rs3792452 polymorphism showed biased transmission of the G allele (χ2 = 4.67, p = 0.031). In the ADHD probands, the subjects with GG genotype in the GRM7 rs37952452 polymorphism had higher mean T-scores for omission errors on the CPT than did those with the GA or AA genotype (t = 3.38, p = 0.001). In addition, the ADHD subjects who were homozygous for the G allele in the GRM7 rs37952452 polymorphism had higher STAIC-T (t = 5.52, p < 0.001) and STAIC-S (t = 2.74, p = 0.007) scores than did those with the GA or AA genotype.ConclusionsThese results provide preliminary evidence of an association between the GRM7 rs37952452 polymorphism and selective attention deficit and anxiety found within the Korean ADHD population.

Previous studies have demonstrated that the MspI and DraI polymorphisms at the alpha-2A-adrenergic receptor gene (ADRA2A) are associated with ADHD. However, few studies have been designed to ascertain the association between the ADRA2A genotypes and the performance on neurocognitive measures in ADHD. The aims of this study were to examine the association of the ADRA2A MspI and DraI polymorphisms with ADHD in Korean subjects, and to determine the relationship between the genotypes of these two polymorphisms and the candidate endophenotypes, as measured by the continuous performance test (CPT). In a case-control study, we assessed 186 ADHD probands and 150 normal controls. One hundred eight trios were studied in a family based association analysis. The transmission disequilibrium test (TDT) analysis showed preferential transmission of the C allele of the DraI polymorphism (chi(2) = 5.88, P = 0.015). In the haplotype analyses, a trend of over-transmission of haplotype C/C was observed (chi(2) = 3.80, P = 0.051). The homozygous subjects for the C allele (C/C genotype) at the DraI polymorphism showed a trend toward a higher mean T-score with respect to the response time variability profiles of the CPT than did those with the other genotypes (C/T + T/T genotypes; P = 0.042). The homozygous subjects for the G allele (G/G genotype) at the MspI polymorphism showed a tendency to have a lower mean T-score with respect to the response time variability profiles of the CPT (P = 0.068). The results of this study provide important evidence for the involvement of the ADRA2A MspI and DraI polymorphisms in the etiology of ADHD in Korean subjects. In addition, our results provide evidence for the possible role of these two polymorphisms in ADHD symptom expression, such as increased response time variability.
