[Ab] Abstract:The first ferronickel manufacturing factory of the Republic of Korea was opened in Gwangyang City on October, 23rd, 2008. There has been public concern regarding heavy metal dust blown from the factory and slag disposal site. Therefore, we evaluated the health impact of the ferronickel factory on Gwangyang City residents by using interrupted time series analysis. We analyzed the monthly incidence patterns of asthma, allergic rhinitis, and dermatitis in Gwangyang City residents from 2004 to 2014. Data were gathered from the National Health Insurance Service database which covers all the hospital use data of entire city residents. Seasonality adjusted quasi-Poisson regression model was used to evaluate whether the operation of the ferronickel factory was associated with the immediate changes in the monthly disease incidence patterns. We set a control region, Yeosu City, near Gwangyang City to ensure that the changes in the disease incidence were specific to Gwangyang City. We conducted sub-regional level analysis to evaluate whether the disease incidence patterns were affected by the distance from the ferronickel factory. The risk estimates after operation of the ferronickel factory showed an abrupt increase in the monthly incidence of unspecified dermatitis [RR (95% CI), 1.75 (1.17-2.60)] and vasomotor and allergic rhinitis [RR (95% CI), 1.23 (1.08-1.39)] in men, and pruritus [RR (95% CI), 1.95 (1.51-2.52)], unspecified dermatitis [RR (95% CI), 1.65 (1.04-2.60)], and vasomotor and allergic rhinitis [RR (95% CI), 1.17 (1.04-1.31)] in women. These findings were significant even after accounting for the changes of the corresponding disease incidence of the comparison city, Yeosu. The effects were greater in young children (aged 0-9) and sub-regions near the ferronickel factory. Our study suggests possible association between the operation of the ferronickel factory and an abrupt increase of pruritus, unspecific dermatitis, and vasomotor and allergic rhinitis in Gwangyang City residents.

[Ab] Abstract:Purpose: Local anesthetic agents such as bupivacaine and lidocaine are commonly used after surgery for pain control. The aim of this prospective study was to evaluate the safety of a mixture of bupivacaine and lidocaine in children who underwent urologic inguinal and scrotal surgery. Materials and Methods: Fifty-five patients who underwent pediatric urologic outpatient surgeries, were prospectively enrolled in this study. The patients were divided into three groups according to age (group I: under 2 years, group II: between 3-4 years, and group III: 5 years and above). Patients were further sub-divided into unilateral and bilateral groups. All patients were injected with a mixture of 0.5% bupivacaine and 2% lidocaine (2:1 volume ratio) at the surgical site, just before the surgery ended. Hemodynamic and electrocardiographic parameters were measured before local anesthesia, 30 minutes after administration of local anesthesia, and 60 minutes after administration. Results: The patients' mean age was 40.5±39.9 months. All patients had normal hemodynamic and electrocardiographic parameters before local anesthesia, after 30 minutes, and after 60 minutes. Also, results of all intervals were within normal values, when analyzed by age and laterality. No mixture related adverse events (nausea, vomiting, pruritus, sedation, respiratory depression) or those related to electrocardiographic parameters (arrhythmias and asystole) were reported in any patients. Conclusions: A mixture of bupivacaine and lidocaine can be safely used in children undergoing urologic inguinal and scrotal surgery. An appropriate dose has no clinically significant hemodynamic or cardiac changes and adverse effects.

[Ab] Abstract:Purpose: This study aimed to evaluate the clinical outcomes and complications of transvaginal minimal mesh repair without using commercially available kits for treatment of pelvic organ prolapse (POP). Materials and Methods: This retrospective cohort study involved 91 women who underwent surgical management of POP with originally designed small mesh between July 2014 and August 2015. This mesh is 56% smaller than the mesh widely used in Japan, and it has only two arms delivered into each right and left sacrospinous ligament. The main study outcome was the anatomic cure rate defined as recurrence of POP quantification (POP-Q) stage II or more. We also assessed changes in the overactive bladder symptom score (OABSS) and prolapse quality of life questionnaire (P-QOL) and evaluated adverse events. Finally, we compared patient backgrounds between the patients with and without recurrence. Results: Prolapse recurred in 10 of 91 patients (11.0%), and all patients with recurrence were diagnosed as POP-Q stage II. As adverse events, only mesh erosion occurred in two (2.2%) and pelvic pain in one (1.1%) of the 91 patients. The OABSS and P-QOL were significantly improved by the operation. When we compared patient backgrounds between the patients with and without recurrence, body mass index was the only factor influencing affecting recurrence. Conclusions: Transvaginal minimal mesh repair resulted in successful outcomes with low mesh-related complications and anatomic recurrence at one year. Furthermore, significant improvement in QOL was offered by this procedure. Our minimal mesh technique should be considered as one treatment option for the management of POP.

[Ab] Abstract:Purpose: To assess the utility of the Manufacturer And User Facility Device Experience (MAUDE) database in objectively capturing adverse events for transvaginal mesh in the United States. Materials and Methods: We reviewed 1,103 individual medical device reports submitted to the MAUDE database that inspired the United States (US) Food and Drug Administration's 2008 Public Health Notification. Entries were compiled into a categorical database that reported manufacturer, brand, reporter type, report source, and type of adverse event. Results: There were numerous examples of missing, duplicated, and non-standardized entries. Analysis revealed 64 reports with duplicated information, and six reports representing multiple patients. Forty-seven percent of medical device reports did not identify a reporter source. At least 28% of reported devices are no longer on the US market. There was wide variability in the quality and completeness of submitted reports and true adverse event rates could not be accurately calculated because the number of total cases was unknown. Conclusions: The MAUDE database was limited in its ability to collect, quantify, and standardize real-life adverse events related to transvaginal mesh. While it functions to collect information related to isolated adverse events, systematic limitations of the MAUDE database, that no doubt extend to other medical devices, necessitate the development of new reporting systems. Alternatives are under development, which may allow regulators to more accurately scrutinize the safety profiles of specific medical devices.

[Ab] Abstract:Purpose: Placement of pre-operative ureteral catheters for colorectal surgery can aid in the identification of ureteral injuries. This study investigates whether simultaneous ureteral catheterization with surgery skin preparation can minimize operating room times without increasing post-operative complications. Materials and Methods: Patients undergoing simultaneous colorectal surgery skin preparation and placement of pre-operative ureteral catheters (n=21) were compared to those who underwent these events sequentially (n=28). Operative time-points of anesthesia ready (AR), surgery procedure start (PS), dorsal lithotomy and catheter insertion (CI) times were compared to assess for differences between groups. Complications were compared between groups. Results: There were no differences in age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA), comorbidities, current procedure terminology (CPT) or International Classification of Diseases, 9th revision (ICD-9) codes between groups. Simultaneous catheterization saved 11.82 minutes of operative time between CI to PS (p=0.005, t-test). There was a significant difference in mean time between CI to PS (11.82 minutes, p=0.008) between simultaneous and sequential ureteral catheterization groups in a linear regression multivariate analysis controlling for age, BMI, CPT and ICD-9 codes. There were 4 complications in the simultaneous (19%) and 3 in the sequential group (11%) (p=0.68). Conclusions: Ureteral catheterization and colorectal surgery skin preparation in a simultaneous fashion decreases the time between CI and PS without significant increase in complications. Mean time saved with simultaneous ureteral catheterization was 11.82 minutes per case. Simultaneous ureteral catheterization may be an option in colorectal surgery and may result in cost savings without additional complications.

[Ab] Abstract:Purpose: This study aims to assess the predictive factors and treatment outcomes of Steinstrasse formation following shock wave lithotripsy (SWL) for ureter stone. Materials and Methods: The medical records of 1,418 ureter stone patients who underwent one-session SWL from November 2005 to May 2013 at our medical institute were retrospectively reviewed. Finally, 551 patients met inclusion criteria. Maximal length and location of stone, stone attenuation (Hounsfield units), and skin-to-stone distance (SSD) were determined on pretreatment non-contrast computed tomography. Results: Of 551 patients, 12 patients (2.2% of total cohort) developed Steinstrasse after one-session SWL. The Steinstrasse incidence was significantly associated with stone size, stone attenuation value, and SSD. Prophylactic ureter stenting was not a statistically significant predictor of Steinstrasse formation. After propensity-score matching, Steinstrasse group showed a significant shorter SSD compare to non-Steinstrasse group. Multivariate logistic regression and Bayesian analysis revealed that stone size, stone attenuation and SSD were significant predictor of Steinstrasse formation following SWL for ureter stone. The Steinstrasse resolved spontaneously in six patients and remaining six patients were treated by additional SWL. None of patients with Steinstrasse required ureteral stenting, percutaneous drainage, or consequent surgical intervention. Conclusions: Steinstrasse formation following SWL for ureter stone was rare event but nonnegligible. Large stone size, high stone attenuation and short SSD were significant predictors of Steinstrasse formation following SWL for ureter stone. Majority of patients with Steinstrasse formation could be treated conservatively in this clinical scenario.

[Ab] Abstract:Purpose: Dietary factors are one of the main causes of urolithiasis. However, little research has evaluated dietary factors related to urolithiasis in Korea. We investigated the various dietary risk factors for urinary stone formation in Korean people. Materials and Methods: We conducted a prospective case-control pilot study. A total of 27 patients newly diagnosed with urolithiasis and 20 applicants without urolithiasis were designated as the patients and the control group, respectively. A face-to-face survey was carried out using a food-frequency questionnaire. After adjustment for physical activity level and total energy intake, multivariate logistic regression models were applied to search for risk factors for urolithiasis. Results: There were no significant differences between the two groups in gender, age, body mass index, family history, or total energy intake. The physical activity level of the control group was significantly higher than that of the patients (p=0.012). The results of the multivariate logistic regression model demonstrated that intake of carbohydrate (odds ratio [OR], 1.055; 95% confidence interval [CI], 1.012-1.099), protein (OR, 1.101; 95% CI, 1.001-1.211), and cereals (OR, 1.012; 95% CI, 1.002-1.023) could increase the risk for urolithiasis. Conclusions: A higher intake of carbohydrate, protein, and cereal may increase the risk of urinary stone formation among Korean people.

[Ab] Abstract:Purpose: The purpose of this study was to evaluate the efficacy of narrow-band imaging (NBI) as a diagnostic tool for detecting bladder tumors during cystoscopy compared with white light cystoscopy (WLC). Materials and Methods: From December 2013 to June 2017, a randomized prospective study was conducted on 198 patients underwent transurethral resection of bladder tumor by a single surgeon. The patients were divided into two groups according to diagnostic method. In Group I, WLC only was performed. In Group II, NBI was additionally performed after WLC. We analyzed the rate of detection of bladder tumors as a primary endpoint. In addition, we evaluated rates of recurrence in each group. Results: There were no significant differences between the two groups in characteristics except hypertension. In the analysis of rates of detection, the probability of diagnosing cancer was 80.9% (114/141) in the WLC group, and the probability of diagnosing cancer using WLC in the NBI group was 85.5% (159/186). After switching from WLC to NBI for second-look cystoscopy in the NBI group, NBI was shown to detect additional tumors with a detection rate of 35.1% (13/37) from the perspective of the patients and 42.2% (27/64) from the perspective of the tumors. The 1-year recurrence-free rate was 72.2% in the WLC group and 85.2% in the NBI group (p=0.3). Conclusions: NBI had benefits for detecting tumors overlooked by WLC. Although the difference in the 1-year recurrence-free rate was not statistically significant, our results showed a trend for higher recurrence in the NBI group.

[Ab] Abstract:Precision medicine is designed to tailor treatments for individual patients by factoring in each person's specific biology and mechanism of disease. This paradigm shifted from a "one size fits all" approach to "personalized and precision care" requires multiple layers of molecular profiling of biomarkers for accurate diagnosis and prediction of treatment responses. Intensive studies are also being performed to understand the complex and dynamic molecular profiles of bladder cancer. These efforts involve looking bladder cancer mechanism at the multiple levels of the genome, epigenome, transcriptome, proteome, lipidome, metabolome etc. The aim of this short review is to outline the current technologies being used to investigate molecular profiles and discuss biomarker candidates that have been investigated as possible diagnostic and prognostic indicators of bladder cancer.

[Ab] Abstract:Purpose: Smoking represents a primary risk factor for the development of urothelial carcinoma (UC) and a relevant factor impacting UC-specific prognosis. Data on the accordant knowledge of UC-patients in this regard and the significance of physicians in the education of UC-patients is limited. Materials and Methods: Eighty-eight UC-patients were enrolled in a 23-items-survey-study aimed to analyse patient knowledge and awareness of their tumor disease with smoking along with physician smoking cessation counselling. Results: The median age of the study patients was 69 years; 26.1% (n=23), 46.6% (n=41), and 27.3% (n=24), respectively, were non-smokers, previous, and active smokers. Exactly 50% of active smokers reported a previous communication with a physician about the association of smoking and their tumor disease; however, only 25.0% were aware of smoking as main risk factor for UC development. Merely 33% of the active smokers had been prompted directly by their physicians to quit smoking. About 42% of active smokers had received the information that maintaining smoking could result in a tumor-specific impairment of their prognosis. Closely 29% of active and about 5% of previous smokers (during the time-period of active smoking) had been offered support from physicians for smoking cessation. No association was found between smoking anamnesis (p=0.574) and pack-years (p=0.912), respectively, and tumor stage of UC. Conclusions: The results of this study suggest that the medical conversation of physicians with UC-patients about the adverse significance of smoking is limited. Implementation of structured educational programs for smoking cessation may be an opportunity to further enhance comprehensive cancer care.
