Abstract
Amputation of the testis is very rare in clinical situations; therefore, most surgeons have no experience with an amputated testis. In this case, a 31-year-old male with schizophrenia amputated both testes due to self-mutilation. We performed replantation surgery via microscopy. On postoperative day 1, he removed his right testis by using his hand, even though his hands were restrained. The second attack disrupted the viability of the right testis. However, after proper management, we checked the normal sex hormone level by preserving the replanted left testis. We evaluated the viability of the replanted testis by performing five examinations, namely, intraoperative indocyanine green injection, testicular scan with technetium pertechnetate, contrast-enhanced computerized tomography, Doppler ultrasonography, and serum testosterone level. In this report, we aimed to describe our rare experience about management with replantation of the amputated testes and evaluation of their viability.

Abstract
BACKGROUND We aimed to assess the trends in urinary tract infections (UTIs) and prognosis of patients with prostate cancer after radical prostatectomy (RP) and radiation therapy (RT) as definitive treatment options. METHODS The data of patients diagnosed with prostate cancer between 2007 and 2016 were collected from the National Health Insurance Service database. The incidence of UTIs was evaluated in patients treated with RT, open/laparoscopic RP, and robot-assisted RP. The proportional hazard assumption test was performed using the scaled Schoenfeld residuals based on a multivariable Cox proportional hazard model. Kaplan-Meier analysis were performed to assess survival. RESULTS A total of 28,887 patients were treated with definitive treatment. In the acute phase (< 3 months), UTIs were more frequent in RP than in RT; in the chronic phase (> 12 months), UTIs were more frequent in RT than in RP. In the early follow-up period, the risk of UTIs was higher in the open/laparoscopic RP group (aHR, 1.63; 95% CI, 1.44-1.83; p < 0.001) and the robot-assisted RP group (aHR, 1.26; 95% CI, 1.11-1.43; p < 0.001), compared to the RT group. The robot-assisted RP group had a lower risk of UTIs than the open/laparoscopic RP group in the early (aHR, 0.77; 95% CI, 0.77-0.78; p < 0.001) and late (aHR, 0.90; 95% CI, 0.89-0.91; p < 0.001) follow-up periods. In patients with UTI, Charlson Comorbidity Index score, primary treatment, age at UTI diagnosis, type of UTI, hospitalization, and sepsis from UTI were risk factors for overall survival. CONCLUSIONS In patients treated with RP or RT, the incidence of UTIs was higher than that in the general population. RP posed a higher risk of UTIs than RT did in early follow-up period. Robot-assisted RP had a lower risk of UTIs than open/laparoscopic RP group in total period. UTI characteristics might be related to poor prognosis.

Abstract
This study assessed the trends in methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) and gemcitabine-cisplatin (GC) regimens in Korean patients with metastatic urothelial carcinoma (UC) and compared the side effects and overall survival (OS) rates of the two regimens using nationwide population-based data. The data of patients diagnosed with UC between 2004 and 2016 were collected using the National Health Insurance Service database. The overall treatment trends were assessed according to the chemotherapy regimens. The MVAC and GC groups were matched by propensity scores. Cox proportional hazard analysis and Kaplan-Meier analysis were performed to assess survival. Of 3108 patients with UC, 2,880 patients were treated with GC and 228 (7.3%) were treated with MVAC. The transfusion rate and volume were similar in both the groups, but the granulocyte colony-stimulating factor (G-CSF) usage rate and number were higher in the MVAC group than in the GC group. Both groups had similar OS. Multivariate analysis revealed that the chemotherapy regimen was not a significant factor for OS. Subgroup analysis revealed that a period of ≥ 3 months from diagnosis to systemic therapy enhanced the prognostic effects of the GC regimen. The GC regimen was widely used as the first-line chemotherapy in more than 90% of our study population with metastatic UC. The MVAC regimen showed similar OS to the GC regimen but needed greater use of G-CSF. The GC regimen could be a suitable treatment option for metastatic UC after ≥ 3 months from diagnosis.

Abstract
PURPOSE The best protocol of cytoreductive nephrectomy (CN) and systemic therapy (ST) in the treatment of metastatic renal cell carcinoma (mRCC) remains unclear. We sought to evaluate overall survival (OS) in patients with mRCC treated with ST with or without CN. METHODS We collected data from the National Health Insurance Service database. We excluded 2 years of washout period, 2 years of follow-up period, other cancer diagnoses within 2 years, and ≥4 months interval between ST and CN. The patients were divided into two groups according to whether CN was performed. Kaplan-Meier, propensity score matching, Cox regression model, and incremental survival analyses were conducted. Additionally, we performed subgroup analysis according to whether cytokine therapy or targeted therapy was used as first-line ST. RESULTS Of 6478 patients, 1707 (26.4%) underwent CN. The CN group showed significantly better OS than the no CN group (p < 0.001). In the cytokine therapy subgroup, patients who underwent CN had significantly higher OS than those who did not (p < 0.001). In the targeted therapy subgroup, no significant difference was found (p = 0.867). In multivariate analysis, CN was associated with better OS in the total cohort (hazard ratio 0.819, p < 0.001). The incremental OS benefit of CN ranged from +0.98 in patients who survived for <24 months to +2.13 in those who survived during all periods. CONCLUSION About a quarter patients with mRCC from a nationwide database were treated with CN and ST. CN was beneficial in specific patients with mRCC. Patient selection is crucial for obtaining the benefits of CN.

Abstract
Purpose This study aimed to evaluate the trend of adjuvant chemotherapy (AC) and neoadjuvant chemotherapy (NAC) in patients who underwent radical nephroureterectomy with bladder cuff excision (NUx) for upper tract urothelial carcinoma (UTUC) to compare the perioperative outcomes and overall survival (OS) between AC and NAC using nationwide population-based data. Materials and methods We collected data on patients diagnosed with UTUC and treated with NUx between 2004 and 2016 using the National Health Insurance Service database, and evaluated the overall treatment trends. The AC and NAC groups were propensity score-matched. Cox proportional hazard and Kaplan-Meier analyses were used to assess survival. Results Of the 8,705 enrolled patients, 6,627 underwent NUx only, 94 underwent NAC, and 1,984 underwent AC. The rate of NUx without perioperative chemotherapy increased from 70.8 to 78.2% (R2 = 0.632; p < 0.001). The rates of dialysis (p = 0.398), TUR-BT (p = 1.000), and radiotherapy (p = 0.497) after NUx were similar. In the Kaplan-Meier curve, the NAC and AC groups showed no significant difference (p = 0.480). In multivariate analysis, treatment with AC or NAC was not associated with OS (hazard ratio 0.83, 95% confidence interval 0.49–1.40, p = 0.477). Conclusion The use of NUx without perioperative chemotherapy has tended to increase in South Korea. Dialysis, TUR-BT, and radiotherapy rates after NUx were similar between the NAC and AC groups. There was no significant difference in OS between the NAC and AC groups. Proper perioperative chemotherapy according to patient and tumor conditions should be determined by obtaining more evidence of UTUC.

Abstract
Purpose Intravesical BCG (bacille Calmette–Guérin) instillation in patients with non-muscle-invasive bladder cancer decreases the risk for tumor recurrence and progression. After one BCG product was discontinued, a chronic global BCG shortage occurred. We focused on identifying a reduced dose of BCG that could maintain efficacy and reduce adverse effects. Materials and Methods We conducted a comprehensive literature search of PubMed, Embase, the Cochrane Library, CINAHL, Web of Science, and Scopus to identify randomized controlled trials through April 2021. The odds ratios (ORs) and 95% confidence intervals (CIs) for the low and standard doses in nine studies were compared. A low dose was defined as a low volume of BCG compared with the standard BCG dose (Armand Frappier, 120 mg; Connaught, 81 mg; Danish 1331, 120 mg; modified Danish 1331, 120 mg; Tokyo 172, 80 mg). Results The low-dose group experienced aggravated recurrence (OR, 1.45; 95% CI, 1.09–1.94; p=0.01) but similar progression (OR, 1.11; 95% CI, 0.76–1.62; p=0.59), similar cancer-specific survival (OR, 1.02; 95% CI, 0.60–1.75; p=0.93), similar overall survival (OR, 1.09; 95% CI, 0.76–1.56; p=0.65), favorable adverse effects (OR, 0.41; 95% CI, 0.28–0.62; p<0.0001), and favorable withdrawal (OR, 0.42; 95% CI, 0.25–0.71; p=0.001). Conclusions Low-dose BCG had more unfavorable outcomes than did standard-dose BCG in terms of recurrence. Tumor progression, cancer-specific survival, and overall survival were similar between the doses. Low-dose BCG improved adverse effects and withdrawal. In the setting of BCG shortage, low-dose BCG may have strong potential as an alternative.

Abstract
PURPOSE The aim of this study was to design a simple and convenient rat model with significant calcium oxalate crystal deposition in the kidney. MATERIALS AND METHODS Sprague-Dawley rats were divided into seven groups of 30 rats each. One group of rats was untreated to serve as controls. Two of the groups of rats were provided with drinking water supplemented with 1% ethylene glycol (EG), and of these two groups, one group was also administered vitamin D. Two groups of rats received intraperitoneal injections of EG, and of these two groups, one group also received vitamin D. Two groups of rats received intraperitoneal injections of glyoxylate, and of these two groups, one group also received vitamin D. We analyzed 24-hour urine samples for urinary constituents for all experimental groups, including calcium, oxalate, citrate, uric acid, pH, and urine volume. The kidneys were examined for crystal deposition using histologic examination and for osteopontin expression using immunohistochemical staining. RESULTS Calcium-oxalate crystals were found in all rats injected with glyoxylate after 1 week. The degree of crystal deposition in rats injected with glyoxylate for 1 week was significantly increased compared with rats fed EG for 4 weeks. CONCLUSIONS Intraperitoneal injection of glyoxylate is a faster, more exact, and more reliable method to produce calcium oxalate crystal deposition in the kidney than previous urolithiasis animal models.

Abstract
A 56-yr-old man with lung adenocarcinoma presented with subsegmental pulmonary thrombosis. Platelet count on presentation was 531 x 10(9)/L. The patient was anticoagulated with subcutaneous low molecular weight heparin (LMWH). Next day, oral anticoagulation was initiated with 5 mg of warfarin once daily with LMWH and LMWH was discontinued at third hospital day. On the third day of oral anticoagulation therapy, he complained of left leg swelling and prolonged painful penile erection of 24 hr-duration. His platelet count reached a nadir 164 x 10(9)/L at that time, and the patient had a deficiency of protein C and S, with an activity level of 16% and 20% of normal value. Warfarin was stopped and he underwent penile aspiration. The next day, left leg edema and penile erection was disappeared, but penile and glans penis necrosis was started. This case illustrates that processes underlying heparin-induced thrombocytopenia (HIT) may also underlie warfarin-induced skin necrosis.

Abstract
The aim of this study was to determine the impact that age and comorbidity status have on both overall and bladder cancer-specific survival of bladder cancer patients. We obtained medical information pertaining to a population of 528 patients with newly diagnosed bladder cancer from Chung-Ang University Hospital cancer registry. The Adult Comorbidity Evaluation-27 (ACE-27) test, which has been previously validated in adult cancer patients, was used to assess comorbidity. We evaluated differences in the demographic and clinical characteristics of included patients, as well as differences in the treatments they received after categorizing them by age. The median age at the time of bladder cancer diagnosis of the entire cohort was 63 years, and the median follow-up time was 97 months. Of the 528 patients who were included in our study, 303 had at least one comorbid condition and 249 died during the follow-up period. When patients were stratified by age, we found that older patients had a higher proportion of severe comorbidities (P < 0.01) than younger patients, and that a lower proportion of them underwent radical cystectomy for invasive bladder cancer (IBC) (P < 0.01). By multivariate analysis, we found that older age was predictive of lower overall survival (OS) and bladder cancer-specific survival (BCSS) rates among patients with superficial bladder cancer (SBC) and of lower OS rates among patients with IBC. We also found that moderate-severe comorbidity status and treatment through a bladder-conserving approach were predictive of lower OS and cancer-specific survival rates among patients with IBC. The disparity between overall deaths and bladder cancer deaths was shown in SBC and increased along with age and higher comorbidity. Age and comorbidity were found to be independent predictive factors of OS and BCSS among bladder cancer patients, and explained the disparity that we observed between overall bladder cancer-specific mortality rates.

Abstract
Expression of alkaline phosphatase(ALP)activity represents a key event during the differentiation processes of osteoblasts, and the level of ALP activity has been routinely used as a relative measure of differentiation stages of osteoblasts. In human osteoblasts, we showed that vitamin D3 analogue, 1,25(OH)2D3, had a stimulatory effect on ALP activity after 3 days, compared with control. The treatment of PD098059, an ERK MAP Kinase inhibitor, had a reducing effect on ALP activity, a differentiation marker in 1,25(OH)2D3-treated primary human osteoblasts. However, SB203580, a potent p38 MAP Kinase inhibitor, had no effect on the differentiation in this system. This indicates that ERK, not p38, is directly related to 1,25(OH)2D3-stimulated ALP activity in primary human osteoblasts. These results also show that the vitamin D3 analogue stimulates ERK1 activation in primary human osteoblasts. This finding provides one of signaling pathways for differentiation in primary human osteoblasts.

Abstract
The present study was undertaken to examine the role of reactive oxygen species (ROS) and glutathione (GSH) in glia cells using human glioma cell line A172 cells. HgCl2 caused the loss of cell viability in a dose-dependent manner. HgCl2-induced loss of cell viability was not affected by H2O2 scavengers catalase and pyruvate, a superoxide scavenger superoxide dismutase, a peroxynitrite scavenger uric acid, and an inhibitor of nitric oxide N(G)-nitro-arginine Methyl ester. HgCl2 did not cause changes in DCF fluorescence, an H2O2-sensitive fluorescent dye. The loss of cell viability was significantly prevented by the hydroxyl radical scavengers dimethylthiourea and thiourea, but it was not affected by antioxidants DPPD and Trlox. HgCl2-induced loss of cell viability was accompanied by a significant reduction in GSH content. The GSH depletion was almost completely prevented by thiols dithiothreitol and GSH, whereas the loss of viability was partially prevented by these agents. Incubation of cells with 0.2 mM buthionine sulfoximine for 24 hr, a selective inhibitor of gamma-glutamylcysteine synthetase, resulted in 56% reduction in GSH content without any change in cell viability. HgCl2 resulted in 34% reduction in GSH content, which was accompanied by 59% loss of cell viability. These results suggest that HgCl2-induced cell death is not associated with generation of H2O2 and ROS-induced lipid peroxidation. In addition, these data suggest that the depletion of endogenous GSH itself may not play a critical role in the HgCl2-induced cytotoxicity in human glioma cells.

Abstract
Reactive oxygen species (ROS) have been implicated in the pathogenesis of a number of neurodegenerative disorders. However, the underlying mechanism of ROS-induced cell injury remains to be defined. This study was undertaken to examine the role of lipid peroxidation and poly (ADP-ribose) polymerase (PARP) activation in H2O2-induced cell death in A172 cells, a human glioma cell line. H2O2 induced a dose- and time-dependent cell death. The cell death was prevented by thiols (dithiothreitol and glutathione), iron chelators (deferoxamine and phenanthroline), H2O2 scavengers (catalase and pyruvate), and a hydroxyl radical scavenger (dimethylthiourea). Antioxidants N,N'-diphenyl-p-phenylenediamine (DPPD) and Trolox had no effect on the H2O2-induced cell death. Lipid peroxidation did not increase in human glioma cells exposed to H2O2. The PARP inhibitor 3-aminobenzamide prevented the cell death induced by H2O2. The PARP activity was increased by H2O2 and the H2O2 effect was prevented by 3-aminobenzamide, dithiothreitol, and phenanthroline. The ATP depletion induced by H2O2 was prevented by catalase, dithiothreitol, phenanthroline, and 3-aminobenzamide, but not by DPPD. These results indicate that the H2O2-induced cell death is mediated by PARP activation but not by lipid peroxidation in human glioma cells.

Abstract
Nitric oxide (NO) and tumor necrosis factor-alpha (TNF-alpha) have been suggested to play an important role in endotoxin-mediated shock and inflammation. In this study, we investigated the effect of aqueous extract of Dichroa febrifuga Lour. (Saxifragaceae) roots, a traditional antimalarial drug, on the production of NO and TNF-alpha. The aqueous extract of D. febrifuga roots (AEDF) inhibited the secretion of NO and TNF-alpha in lipopolysaccharide (LPS) and/or interferon-gamma (IFN-gamma)-stimulated mouse peritoneal macrophages, without affecting cell viability. The protein level of inducible nitric oxide synthase (iNOS) in peritoneal macrophages was also decreased by AEDF. In addition, the serum level of NO was reduced by i.p. administration of AEDF. These results suggest that AEDF suppresses the endotoxin-induced inflammatory responses through inhibiting the production of NO and TNF-alpha, and could be used as an anti-inflammatory drug.

Abstract
BACKGROUND The purpose of this study was to compare the 2-hr excess postexercise oxygen consumption (EPOC), respiratory exchange ratio (RER), and rectal temperature (RT) after four-exercise bouts of varying intensity and duration, with and without glucose in milk (GM) ingestion. METHODS EXPERIMENTAL DESIGN subjects completed the exercise tests in random order 4 times on the same weekday. The four experimental exercise conditions were low intensity, long duration with GM (LL & GM), low intensity, long duration without GM (LL & NGM), high intensity, short duration with GM (HS & GM), and high intensity, short duration without GM (HS & NGM). PARTICIPANTS ten male college students (20.8 +/- 0.6) yrs participated voluntarily. Measures. Two-way repeated measures ANOVA (exercise condition x time) was used to compare the variables. RESULTS Mean EPOC for the 2-hr postexercise period for HS & GM (211.5 ml O2/kg) was significantly greater than EPOC for HS & NGM (154.8 ml O2/kg), LL & GM (140.4 ml O2/kg) and LL & NGM (125.2 ml O2/kg). Mean recovery oxygen uptakes were 6.4, 5.7, 4.5, and 4.2 ml/min/kg with HS & GM, HS & NGM, LL & GM and LL & NGM, respectively. Mean RERs for high intensity exercises were significantly lower than RERs for low intensity exercises during the recovery period. Mean RT for HS & GM (37.60 degrees C) and HS & NGM (37.43 degrees C) were significantly higher than RT for LL & GM (37.19 degrees C) and LL & NGM (37.15 degrees C) during the recovery period. CONCLUSION These results suggest that preexercise intake of GM increases EPOC above that observed in the fasting condition, and high intensity short duration exercise increases fat oxidation during recovery period more than low intensity long duration exercise.
