Purpose:
We investigated the effects of economic status (classified based on insurance type and residential area) on oncological outcomes of prostate cancer using a nationwide database. We additionally investigated oncological outcomes based on economic status and residential area in patients who underwent surgical treatment.
Materials and Methods:
The study included 75,518 men with newly diagnosed prostate cancer between 2009 and 2018 in whom oncological outcomes were investigated based on economic status and residential area. Among the 75,518 men with prostate cancer, the data of 29,973 men who underwent radical prostatectomy were further analyzed. Multivariate analysis was performed to determine the effects of economic status and residential area on postoperative oncological outcomes.
Results:
Among the 75,518 patients with prostate cancer, 3,254 (4.31%) were medical aid beneficiaries. The 5-year overall survival rates were 81.2% and 64.8% in the health insurance and medical aid groups, respectively. Radical prostatectomy was more common in the health insurance group, and surgical intervention was significantly affected by the residential area. Among patients who underwent surgery, 5-year androgen deprivation therapy–free and overall survival were better in the health insurance group. Multivariate analysis showed that insurance type and residential area were significantly associated with the androgen deprivation therapy–free and overall survival after adjustment for other variables.
Conclusion
Economic status and residential area were shown to affect not only treatment patterns but also post-diagnosis and postoperative oncological outcomes. Political support for early diagnosis and appropriate treatment of prostate cancer is warranted for medically vulnerable populations.

Objectives:
We evaluated the efficacy of a medial arthroscopic approach to the coxofemoral joint of dogs by analyzing the joint visible area and performing a safety analysis.
Methods:
Arthroscopic approaches to the coxofemoral joint were made in five cadavers using a traditional (dorsal) and novel (medial) approach. Three observers scored the visible area of images and videos of the acetabulum and femur. A safety analysis was performed via dissection of the medial hind limb. The distance between neurovascular structures and arthroscopic portals was measured.
Results:
The acetabulum was more visible in the dorsal than in the medial approach, with mean visualization scores of 16 ± 0.00 and 11.83 ± 1.26, respectively. The medioventral side of the femur was significantly more visible in the medial than in the dorsal approach, with mean visualization scores of 3.9 ± 0.99 and 6.93 ± 0.58, respectively. Safety analysis confirmed the medial portal site was safe, provided that the surgeon has comprehensive knowledge of the joint. The minimum distance from the arthroscopic medial portals to the nearest neurovascular structures was 2.5 mm.
Conclusions
A medial arthroscopic approach to the canine coxofemoral joint has potential clinical application. Dorsal and medial approaches differ significantly and have distinct purposes. The medial approach is useful to access the ventromedial joint, making it an eligible diagnostic method for an arthroscopic evaluation of this area.

Purpose:
We assessed the effects of preoperative bladder compliance on the long-term functional outcomes, especially focused on postoperative storage symptom changes, after laser prostatectomy.
Materials and Methods:
From January 2008 to March 2014, 1,608 men who underwent laser prostatectomy, including holmium laser enucleation or photo-vaporization of the prostate, were included in the analysis. We divided patients into 3 groups according to bladder compliance on a baseline urodynamic study: <12.5, 12.5–25, ≥25 mL/cmH2O. A multivariable analysis was performed to determine the impact of bladder compliance on changes in long-term functional outcomes after laser prostatectomy.
Results:
Bladder compliance was less than 12.5 mL/cmH2O in 50 (3.1%), 12.5–25 mL/cmH2O in 232 (14.4%) patients. As bladder compliance decreased, the baseline International Prostate Symptom (IPSS) total score and storage sub-score were increased; the voiding sub-score remain unchanged. At postoperative 12 and 36 months, absolute improvements in the IPSS total score and storage sub-score were higher in <12.5 mL/cmH2O group compared to other groups, although those were equivalent at postoperative 1 months. On the multivariable analysis, decreased bladder compliance <12.5 mL/cmH2O was significantly associated with superior improvement in storage sub-score at postoperative 36 months, although it was not associated with voiding sub-score.
Conclusions
In patients with preoperative bladder compliance <12.5 mL/cmH2O, storage symptoms could be further improved at 36 months after laser prostatectomy compared to others. Thus, laser prostatectomy could be a considerable treatment option for patients with severely decreased bladder compliance.

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.

Background:
Several cases of pediatric acute hepatitis of unknown etiology related to adenoviral infections have been reported in Europe since January 2022. The aim of this study was to compare the incidence, severity, possible etiology, and prognosis of the disease with those in the past in Korea.
Methods:
The surveillance group collected data between May and November 2022 using a surveillance system. Acute hepatitis of unknown etiology was defined in patients aged < 16 years with a serum transaminase level > 500 IU/L, not due to hepatitis A-E or other underlying causes. For comparison, data from 18 university hospitals were retrospectively collected as a control group between January 2021 and April 2022.
Results:
We enrolled 270 patients (mean age, 5 years). The most common symptom was fever. However, the incidence was similar between 2021 and 2022. Liver function test results, number of patients with acute liver failure (ALF), liver transplantation (LT), death, and adenovirus detection rates did not differ between the two groups. None of the adenoviruspositive patients in either group experienced ALF, LT, or death. In the surveillance group, adenovirus-associated virus-2 was detected in four patients, one of whom underwent LT. Patients with an unknown etiology showed significantly higher bilirubin levels, a lower platelet count, and a higher LT rate than patients with a possible etiology.
Conclusion
The incidence of pediatric acute hepatitis of unknown etiology and adenovirus detection rate have not increased in Korea.
