The association between celebrity suicide and subsequent increase in suicide rates among the general population has been suggested. Previous studies primarily focused on celebrity suicides in the 2000s. To better understand the association, this study examined the impacts of celebrity suicides on subsequent suicide rates using the data of Korean celebrity suicides between 1990 and 2010. Nine celebrity suicides were selected by an investigation of media reports of suicide deaths published in three major newspapers in Korea between 1990 and 2010. Suicide mortality data were obtained from the National Statistical Office of Korea. Seasonal autoregressive integrated moving average models with intervention analysis were used to test the impacts of celebrity suicides, controlling for seasonality. Six of the 9 celebrity suicides had significant impacts on suicide rates both in the total population and in the same gender- or the same age-subgroups. The incident that occurred in the 1990s had no significant impact on the overall suicide rates, whereas the majority of the incidents in the 2000s had significant influences for 30 or 60 days following each incident. The influence of celebrity suicide was shown to reach its peak following the suicide death of a renowned actress in 2008. The findings may suggest a link between media coverage and the impact of celebrity suicide. Future studies should focus more on the underlying processes and confounding factors that may contribute to the impact of celebrity suicide on subsequent suicide rates.

PURPOSE: To evaluate the impact of photoselective vaporization of the prostate (PVP) with a 120-W GreenLight high-performance system on erectile function in a 2-year follow-up study. MATERIALS AND METHODS: One hundred seventy-seven patients who underwent PVP during 2008 to 2012 were analyzed retrospectively. The patients were divided into 5 groups according to their preoperative 5-item International Index of Erectile Function (IIEF-5) scores: Group I (IIEF-5: 5~7, n=28), II (IIEF-5: 8~11, n=47), III (IIEF-5: 12~16, n=43), IV (IIEF-5: 17~21, n=34), and V (IIEF-5: 22~25, n=25). The patients were assessed before surgery and 6, 12, and 24 months after the PVP. Their International Prostate Symptom Score/quality of life, maximum urinary flow rate/post-void residual urine volume, and IIEF-5 scores were measured at each visit. RESULTS: The mean age and presence of hypertension were significantly different among the 5 groups. Perioperative parameters and postoperative complication rates showed no statistical differences. After PVP, voiding parameters were significantly improved in all the groups and sustained during the 2-year follow-up. The postoperative IIEF-5 scores fell slightly overall, while group V showed the largest significant deterioration. In multivariate analysis, body mass index (BMI) was the only independent predictor of decreased erectile function after PVP. CONCLUSIONS: Erectile function declined in all the groups after PVP, with the most extensive deterioration observed in patients with normal erectile function preoperatively. Preoperative BMI was the only independent risk factor for a meaningful decrease in erectile function after PVP.

PURPOSE: To assess outcomes from patients who underwent radical prostatectomy and had their indwelling urinary catheter removed on postoperative day (POD) 4 or 7. MATERIALS AND METHODS: The medical records of 107 consecutive patients receiving radical prostatectomy (RP), were retrospectively reviewed. Patients were categorized into two groups according to length of catheterization. Group 1 (n=40) had the urethral catheter removed on postoperative day (POD) 4, and group 2 (n=67) had the catheter removed on POD7. Group 1 had urethral catheter removal following no leakage on intraoperative leak testing and POD4 cystography, whilst group 2 exhibited leakage at POD4 and instead had routine POD7 urethral catheter removal if there was evidence of no leakage of POD7 cystography. Incontinence was checked according to the use of protective pad. RESULTS: The mean age of the study population was 67.0 years. acute urinary retension (AUR) following catheter removal occurred in 6 of the cohort (5.6%); 3 patients (7.5%) from group 1 and 3 (4.5%) from group 2 (p=0.669). The overall continence rate was 39.3%, 68.2%, 80.4%, and 91.6% at 1, 3, 6, and 12 months respectively. Importantly, the incontinence recovery pace of group 1 was notably higher than that of group 2 (p=0.001). Neither group exhibited bladder neck contracture. Intraoperative factors influencing the decision to remove catheter at POD4 following RP, are bladder neck reconstruction (OR=3.792, p=0.010) and nerve sparing (OR=6.646, p=0.008). CONCLUSIONS: Selective early urethral catheter removal may shorten the length of incontinence recovery, without increasing the risk of AUR and bladder neck contracture.

Retrograde intrarenal surgery (RIRS) has been accepted as the first-line option for surgical treatment of upper urinary tract pathologies including stones and tumors. With the development of surgical instruments with improved deflection mechanisms, visualization, and durability, RIRS has taken on an expanding role in treating urinary calculi located in the upper urinary tract, as it compensates for the shortcomings of shockwave lithotripsy and percutaneous nephrolithotomy. RIRS can also be considered a conservative treatment option for upper urinary tract urothelial cancer or as a means of intensive postoperative surveillance after radical treatment of urinary tract urothelial cancer. RIRS has a steep learning curve and various surgical techniques can be utilized during operations. The use of particular surgical instruments should take into consideration of the gain in surgical efficiency, decrease in complications, and cost-benefit tradeoff.

Objectives: ：The purpose of this study was to quantitatively assess the degree of Graves’ Disease affecting mental health through the results of multiphasic military personality inventory (MPI) in 19-year-old men. Methods: ：We collected and analyzed the results of the MPI for 592 healthy subjects and 148 Graves’ disease patients among the 19-year-old men who visited the Military Manpower Administration from February 2008 to January 2010. Results: ：Among demographic characteristics, both Graves’ disease and control group are 19-year-old men. Educational level, socioeconomic status, parental relationship, and BMI were not statistically different between the two groups (χ2 =0.089, p=0.766; χ2 =5.090, p=0.278; χ 2 =5.988, p=0.112 ; t=-0.635, p=0.526). In the MPI, among validity scales, the score of the faking-good subscale was significantly lower in the Graves’ group (t=3.507, p<0.001), but in the faking-bad and infrequency subscales scores were not significantly different between two groups (t=-1.700, p=0.090; t=-0.519, p=0.604). Among the neurosis scale, anxiety, depression, somatization, and personality disor-der subscale scores were all significantly higher in Graves’ disease group (t=-3.323, p<0.001; t=-4.210, p<0.001; t=-6.202, p<0.001; t=-2.872, p<0.01). Among the psychopath scale, each score of schizophrenia and paranoia subscales were not statistically different between the two groups (t=-0.158, p=0.874; t=-0.846, p=0.398). Conclusions ：According to MPI result, we can confirm that Graves’ disease patients in 19-year-old-men may appear features such as anxiety, depression, somatization and personality tendency (introversion or impulsivity) than the control group.

Objectives: The Panbio COVID-19 Ag Rapid Test Device (Panbio COVID-19 Ag, Abbott Rapid Diagnostics) is a lateral flow immunochromatographic assay targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleoprotein in nasopharyngeal specimens for the diagnosis of coronavirus disease 2019 (COVID-19). This study aimed to verify the performance of the Panbio COVID-19 Ag for implementation in clinical laboratories. Methods: Sixty nasopharyngeal swab specimens (30 positive and 30 negative) dipped in transport medium, and COVID-19 was confirmed using real-time RT-PCR using Allplex SARS-CoV-2 assay (Seegene), were tested using the Panbio COVID-19 Ag. Reproducibility was evaluated using positive and negative control materials. Sensitivity and specificity were calculated based on the results of realtime RT-PCR as the standard test method. Results: Reproducibility was confirmed by the consistent results of repeated tests of the quality control materials. The overall sensitivity and specificity of Panbio COVID-19 Ag were 50.0% and 100.0%, respectively. Panbio COVID-19 Ag demonstrated high sensitivity (88.2%) in analyzing the detection limit cycle threshold (Ct) value of 26.67 provided by the manufacturer as a positive criterion, and the sensitivity was 100.0% for the positive criterion of Ct values <25, although it was less sensitive for Ct ≥ 25. Conclusion Considering the high sensitivity for positive samples with Ct values <25 and the rapid turnaround of results, Panbio COVID-19 Ag can be used in clinical laboratories to diagnose COVID-19 in limited settings.

PURPOSE: We evaluated the prognostic value of the 5-tiered grade group in Korean patients who underwent radical prostatectomy. MATERIALS AND METHODS: Between 1996 and 2016, a number of 2,883 consecutive patients who underwent radical prostatectomy were included for the analysis. The impacts of biopsy and pathologic grade group on predicting biochemical recurrence (BCR) were assessed using multivariate analysis. Median follow-up duration was 49.0 months. RESULTS: Mean age was 66.5 years and prostate-specific antigen (PSA) was 11.8 ng/mL. Prostate cancer was locally advanced on magnetic resonance imaging in 13.4%. Biopsy grade group was as follows: 1 (46.8%), 2 (19.8%), 3 (14.2%), 4 (14.1%), and 5 (5.1%). Pathology stage was ≤T2 in 63.6%, T3a in 26.0%, and T3b/T4 in 10.4% patients. Pathologic grade was as follows: 1 (31.3%), 2 (37.9%), 3 (20.2%), 4 (4.7%), and 5 (5.1%). In multivariate analysis using biopsy-related variables, biopsy grade group (1, reference; 2, hazard ratio [HR], 1.771; p=0.001; 3, HR, 2.736; p < 0.001; 4, HR, 2.966; p < 0.001; 5, HR, 3.707; p < 0.001) was associated with BCR-free survival, PSA level and % positive core. In multivariate analysis using pathologic outcomes, pathologic grade group (1, reference; 2, HR, 1.882; p < 0.001; 3, HR, 3.352; p < 0.001; 4, HR, 3.890; p < 0.001; 5, HR: 3.118, p < 0.001) was associated with BCR-free survival in addition to pathologic stage and positive surgical margin. CONCLUSIONS: New 5-tiered grading system could be useful for predicting oncological outcomes in Korean patients although its role for distinguishing outcomes between patients with grade groups 3–5 need to be validated before wide application of this grade system in Korea.

PURPOSE: Endoscopic thyroidectomy using a cervico-axillary approach (CAA) provides optimal visualization with a smaller dissection plane. Despite the excellent cosmetic results and high patient satisfaction, the surgical and oncologic safety of CAA endoscopic surgery has not been fully established. The present study evaluated the feasibility, safety, and surgical outcomes of CAA endoscopic thyroidectomy. METHODS: From October 2009 to April 2012, 100 patients with papillary thyroid cancer underwent CAA endoscopic thyroidectomy. Patient demographics, pathologic features, and surgical outcomes including complications and recurrence were collected. RESULTS: CAA endoscopic thyroidectomy was successful in all patients, and none required conversion to open thyroidectomy. All patients underwent ipsilateral thyroid lobectomy with or without central compartment neck dissection. The mean tumor size was 1.0±0.6 cm (range, 0.5~1.6), and 35.0% of tumors showed extrathyroidal extension. The mean number of harvested lymph nodes was 4.1±4.4, and metastasis was found in 12.0% of patients. The mean surgical time was 175.2±50.4 min, mean intraoperative blood loss was 42.5±69.2 ml, and the mean hospital stay was 3.3±0.6 days. There were five cases of postoperative transient hypocalcemia and eight cases of vocal cord palsy. No permanent complication or postoperative bleeding was observed. Patients continued to be seen for a median period of 63.7 months, and no recurrence of thyroid cancer was seen. CONCLUSION: CAA endoscopic thyroidectomy is a feasible and safe procedure for low-risk thyroid cancer, with excellent cosmesis. It can be recommended as an alternative option for selected patients with low-risk thyroid cancer.

Background and Objectives: To analyze mapping changes in dynamic range (DR) and neural response threshold (NRT) as prognostic factors for cochlear implant (CI). To analyze whether postoperative speech perception performance could be predicted using DR change and initial NRT. Subjects and Methods: The speech comprehension data of 33 patients with CI were retrospectively analyzed after 1, 3, 6, and 12 months of device use. All subjects were adult, postlingually hearing-impaired, and Cochlear Nucleus CI users. Speech perception performance was evaluated using aided pure tone audiometry, consonant, vowel, one-word, two-word, and sentence tests. Results: The averages of initial NRT and DR changes were 197.8±25.9 CU (104–236) and 22.2±18.4 CU (-15–79), respectively. The initial DR was 40.8±16.6 CU. The postoperative DR was 50.3±16.4 CU at 3 months, 58±12.3 CU at 6 months, and 62.9±10.4 CU at 12 months. A gradual increase of DR was observed during the first year of CI. Compared with the initial DR, significant increases in DR were observed at 3 (p<0.05), 6 (p<0.001), and 12 (p<0.001) months. Compared with initial speech performance outcomes, a significant gain in all performance outcomes was achieved at 12 months (p<0.001). Conclusions Patients with low NRT after CI surgery could initially set DR to a wider range and had better final speech perception outcomes. Conversely, patients with high NRT after CI surgery had to set up a gradual increase in DR while adjusting the T-C level, and the final speech perception outcomes were worse. DR and NRT, the main CI mapping variables, can help predict prognosis related to speech perception outcomes after CI surgery. In conclusion, the post-CI speech perception is better with a lower initial NRT, wider final DR, or younger age.

PURPOSE: Although the prevalence of erectile dysfunction (ED) can be affected by social changes, this association has not been well evaluated. We aimed to evaluate the prevalence and risk factors of ED through a 10-year-interval web-based survey using the previous database of same group of panels, with same methodology. MATERIALS AND METHODS: We sent e-mails and surveyed the panels registered in the Internet survey agency. RESULTS: In total, 900 participants were recruited in 2016. The age-adjusted overall prevalences of self-reported ED (self-ED) and International Index of Erectile Function-5-assessed ED (IIEF-5-ED; score ≤21) in the 2016 study were 3.2% and 44.8%, respectively, which were lower than the prevalences of 8.1% (p=0.036) and 51.4% (p=0.323), respectively, in the 2006 study. The risk factors of IIEF-5-ED in their 20s and 30s in 2016 were psycho-social factors such as depression, low frequency of conversation about sex with sexual partner. The risk factors of IIEF-5-ED in their 40s to 60s in 2016 were organic factors, such as hypertension, diabetes mellitus, smoking, alcohol use, and self-reported premature ejaculation. CONCLUSIONS: Although the age-adjusted overall prevalence of self-ED has decreased during a decade, there was no difference in the age-adjusted overall prevalence of IIEF-5-ED. Psycho-social support may be important for young men with ED and overall healthcare can be helpful for elderly men with ED.
