Objectives:
Very limited previous research has investigated the utility weights of prostate-related diseases in the general population in Korea. The purpose of this study was to calculate the utility of prostate-related health states in the Korean general public using the standard gamble (SG) method.
Methods:
Seven health states for hypothetical prostate cancers, 1 for benign prostate hyperplasia, and 1 for erectile dysfunction were developed based on patient education material and previous publications. In total, 460 responses from the Korean general population were used to analyze the utility of prostate-related health states. Computer-assisted personal interviews were conducted, and utility values were measured using a visual analogue scale (VAS) and SG. Mean utility values were calculated for each prostate-related health state.
Results:
The mean utility values of prostate cancer derived from SG ranged from 0.281 (metastatic castration-refractory prostate cancer) to 0.779 (localized prostate cancer requiring prostatectomy). The utility value of benign prostate hyperplasia was 0.871, and that of erectile dysfunction was 0.812. The utility values obtained using the SG method in all conditions were higher than the values obtained by VAS. There were no significant demographic variables affecting utility values in multivariate analysis.
Conclusions
Our findings might be useful for economic evaluation and utility calculation of screening and interventions for prostate-related conditions in the general population.

We evaluated the long-term results of feminizing genital reconstruction in patients with genital ambiguity with high vaginal confluence. The medical records of 10 consecutive patients with ambiguous genitalia and high vaginal confluence who underwent feminizing genital reconstruction from 1996 to 2007 were reviewed. Seven patients had congenital adrenal hyperplasia, one had mixed gonadal dysgenesis, one had partial androgen insensitivity, and one had 5-alpha reductase deficiency syndrome. Median age at operation was 21 months (range, 2-47 months). Median follow up was 7.7 yr. Of the six patients who underwent feminizing genital reconstruction with the Gonzalez method, three had good results. Of the other three patients, one had a urethrovaginal fistula and underwent fistula repair 9 yr after, one had distal vaginal stenosis and underwent revision vaginoplasty 9 yr after, and one had a urethrovaginal fistula and urethral stricture. The patient with urogenital mobilization had persistent urogenital sinus. Feminizing genitoplasty using the Gonzalez method showed good long-term results in patients with ambiguous genitalia and Congenital adrenal hyperplasia. The procedure is less invasive than other approaches and results in excellent cosmetic outcomes; and complications can be corrected by relatively simple procedures.

Dysbiosis in gut microbiota is known to contribute to development of irritable bowel syndrome. We tried to investigate the effect of Bifidobacterium longum on repeated water avoidance stress (WAS) in a Wistar rat model. The three groups (no-stress, WAS, and WAS with B. longum) of rats were allocated to sham or WAS for 1 hour daily for 10 days, and B. longum was administered through gavage for 10 days. Fecal pellet numbers were counted at the end of each 1-hour session of WAS. After 10 days of repeated WAS, the rats were eutanized, and the feces were collected. WAS increased fecal pellet output (FPO) significantly in both sexes (P < 0.001), while the female B. longum group showed significantly decreased FPO (P = 0.005). However, there was no consistent change of myeloperoxidase activity and mRNA expression of interleukin-1ββ and TNF-αα. Mast cell infiltration at colonic submucosa increased in the female WAS group (P = 0.016). In terms of fecal microbiota, the repeated WAS groups in both sexes showed different beta-diversity compared to control and WAS with B. longum groups. WAS-induced mast cell infiltration was reduced by the administration of B. longum in female rats. Moreover, administration of B. longum relieved WAS-caused dysbiosis, especially in female rats. In conclusion, B. longum was beneficial for WAS-induced stress in rats, especially in females.

PURPOSE: The use of complementary and alternative medicine (CAM) is very common among patients with a urological malignancy. We assessed the prevalence and patterns of use of complementary therapies among patients with bladder, prostate and renal cancers. MATERIALS AND METHODS: Between May and July 2004, we conducted a survey to assess the use of CAM at 13 outpatient clinics in Korea. Seven hundred and eleven patients with bladder (269), prostate (300) or renal cancers (142) were selected to answer a self-administered questionnaire on CAM, which were then analyzed. RESULTS: Among 711 patients with urological malignancies, 279 (39.2%) had been treated with at least one type of CAM, in addition to conventional Western treatment. The cancer patients treated with radiation therapy or immunotherapy were more likely to employ CAM than those using other therapies. Age, gender, cancer type, occupations, religions, level of education and disease status (stable or progressive) were not associated with the prevalence of CAM. 44.3% of CAM users wanted to discuss CAM techniques with their doctors, but only 24.8% received an explanation of there use. CONCLUSIONS: CAM is used by a large number of patients with urological malignancies, particularly in those undergoing radiation therapy or immunotherapy. Urologists need to have an accurate knowledge and apprehension of CAM. The possible effects and side effects should be defined, with appropriate guidelines recommended for patients with a urological malignancy.

Roseburia faecis, a butyrate-producing, gram-positive anaerobic bacterium, was evaluated for its usefulness against repeated water avoidance stress (WAS)-induced irritable bowel syndrome (IBS) in a rat model, and the underlying mechanism was explored.We divided the subjects into three groups: one without stress exposure, another subjected to daily 1-hour WAS for 10 days, and a third exposed to the same WAS regimen while also receiving two different R. faecis strains (BBH024 or R22-12-24) via oral gavage for the same 10-day duration. Fecal pellet output (FPO), a toluidine blue assay for mast cell infiltration, and fecal microbiota analyses were conducted using 16S rRNA metagenomic sequencing. Predictive functional profiling of microbial communities in metabolism was also conducted. FPO and colonic mucosal mast cell counts were significantly higher in the WAS group than in the control group (male, P = 0.004; female, P = 0.027). The administration of both BBH024 (male, P = 0.015; female, P = 0.022) and R22-12-24 (male, P = 0.003; female, P = 0.040) significantly reduced FPO. Submucosal mast cell infiltration in the colon showed a similar pattern in males. In case of fecal microbiota, the WAS with R. faecis group showed increased abundance of the Roseburia genus compared to WAS alone. Moreover, the expression of a gene encoding a D-methionine transport system substrate-binding protein was significantly elevated in the WAS with R. faecis group compared to that in the WAS (male, P = 0.028; female, P = 0.025) group. These results indicate that R. faecis is a useful probiotic for treating IBS and colonic microinflammation.

We investigated the efficacy and tolerability of various anticholinergics in Korean children with non-neurogenic overactive bladder (OAB). A total of 326 children (males:females= 157:169) aged under 18 yr (mean age 7.3+/-2.6 yr) who were diagnosed with OAB from 2008 to 2011 were retrospectively reviewed. The mean duration of OAB symptoms before anticholinergic treatment was 16.9+/-19.0 months. The mean duration of medication was 5.6+/-7.3 months. Urgency urinary incontinence episodes per week decreased from 1.9+/-3.1 to 0.4+/-1.5 times (P<0.001). The median voiding frequency during daytime was decreased from 9.2+/-5.4 to 6.3+/-4.2 times (P<0.001). According to 3-day voiding diaries, the maximum and average bladder capacity were increased from 145.5+/-66.9 to 196.8+/-80.3 mL and from 80.8+/-39.6 to 121.8+/-56.5 mL, respectively (P<0.001). On uroflowmetry, maximum flow rate was increased from 17.6+/-8.4 to 20.5+/-8.2 mL/sec (P<0.001). Adverse effects were reported in 14 (4.3%) children and six children (1.8%) discontinued medication due to adverse effects. Our results indicate that anticholinergics are effective to improve OAB symptoms and tolerability was acceptable without severe complications in children.

Purpose:
This study aimed to compare the short-term outcomes and safety profiles of androgen-deprivation therapy (ADT)+abiraterone/prednisone with those of ADT+docetaxel in patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC).
Materials and Methods:
A web-based database system was established to collect prospective cohort data for patients with mHSPC in Korea. From May 2019 to November 2022, 928 patients with mHSPC from 15 institutions were enrolled. Among these patients, data from 122 patients who received ADT+abiraterone/prednisone or ADT+docetaxel as the primary systemic treatment for mHSPC were collected. The patients were divided into two groups: ADT+abiraterone/prednisone group (n=102) and ADT+docetaxel group (n=20). We compared the demographic characteristics, medical histories, baseline cancer status, initial laboratory tests, metastatic burden, oncological outcomes for mHSPC, progression after mHSPC treatment, adverse effects, follow-up, and survival data between the two groups.
Results:
No significant differences in the demographic characteristics, medical histories, metastatic burden, and baseline cancer status were observed between the two groups. The ADT+abiraterone/prednisone group had a lower prostate-specific antigen (PSA) progression rate (7.8% vs. 30.0%; p=0.011) and lower systemic treatment discontinuation rate (22.5% vs. 45.0%; p=0.037). No significant differences in adverse effects, oncological outcomes, and total follow-up period were observed between the two groups.
Conclusions
ADT+abiraterone/prednisone had lower PSA progression and systemic treatment discontinuation rates than ADT+docetaxel. In conclusion, further studies involving larger, double-blinded randomized trials with extended follow-up periods are necessary.
