Purpose: To analyze the degree of psychological distress experienced pre- and postoperatively in patients who underwent radical prostatectomy after being diagnosed with prostate cancer. Materials and Methods: Patients diagnosed with prostate cancer who underwent radical prostatectomy without history of psychiatric disorders were included in this study. The degree of psychological distress was evaluated using hospital anxiety and depression scale (HADS) and distress thermometer (DT) questionnaires preoperatively and at 1, 3, 6, and 12 months postoperatively. Results: Distress was high preoperatively and decreased over the entire period. In addition, HADS-anxiety and HADS-depression scores showed an improved severity, shifting from an abnormal state to a borderline state in some patients. However, the DT score, including emotional problems, spiritual concerns, physical problems, family problems, and practical problems, was slightly higher at 1 month postoperatively compared to preoperatively. Furthermore, even at 12 months postoperatively, about one fifth of patients surveyed had a DT score of 4 or higher, requiring psychiatric intervention. Conclusions Before and after radical prostatectomy, a significant number of patients complained of distress such as anxiety, depression, and insomnia, and they needed help from a specialist because of psychological distress even 12 months postoperatively.Therefore, a close evaluation of the patient’s psychological distress and supportive treatment are needed during the entire pre- and postoperative period.

Background: There is no clear consensus on the optimal treatment with curative intent for patients with positive surgical margins (PSMs) following radical prostatectomy (RP). The aim of this study was to investigate the perceptions and treatment patterns of Korean urologists regarding the resection margin after RP. Methods: A preliminary questionnaire was prepared by analyzing various studies on resection margins after RP. Eight experienced urologists finalized the 10-item questionnaire.In July 2019, the final questionnaire was delivered via e-mail to 105 urologists in Korea who specialize in urinary cancers. Results: We received replies from 91 of the 105 urologists (86.7%) in our sample population.Among them, 41 respondents (45.1%) had performed more than 300 RPs and 22 (24.2%) had completed 500 or more RPs. In the question about whether they usually performed an additional biopsy beyond the main specimen, to get information about surgical margin invasion during surgery, the main opinion was that if no residual cancer was suspected, it was not performed (74.7%). For PSMs, the Gleason score of the positive site (49.5%) was judged to be a more important prognostic factor than the margin location (18.7%), multifocality (14.3%), or margin length (17.6%). In cases with PSMs after surgery, the prevailing opinion on follow-up was to measure and monitor prostate-specific antigen (PSA) levels rather than to begin immediate treatment (68.1%). Many respondents said that they considered postoperative radiologic examinations when PSA was elevated (72.2%), rather than regularly (24.4%). When patients had PSMs without extracapsular extension (pT2R1) or a negative surgical margin with extracapsular extension (pT3aR0), the response ‘does not make a difference in treatment policy’ prevailed at 65.9%. Even in patients at high risk of PSMs on preoperative radiologic screening, 84.6% of the respondents said that they did not perform neoadjuvant androgen deprivation therapy. Most respondents (75.8%) indicated that they avoided nerve-sparing RP in cases with a high risk of PSMs, but 25.7% said that they had tried nerve-sparing surgery. Additional analyses showed that urologists who had performed 300 or more prostatectomies tended to attempt more nerve-sparing procedures in patients with a high risk of PSMs than less experienced surgeons (36.6% vs. 14.0%; P = 0.012). Conclusion The most common response was to monitor PSA levels without recommending any additional treatment when PSMs were found after RP. Through this questionnaire, we found that the perceptions and treatment patterns of Korean urologists differed considerably according to RP resection margin status. Refined research and standard practice guidelines are needed.

Purpose: To investigate whether estramustine phosphate (EMP) monotherapy is applicable to castration-resistantprostate cancer (CRPC) patients who cannot receive cytotoxic chemotherapy. Materials and Methods: This retrospective single-arm study was conducted in CRPC patients who had notexperienced cytotoxic chemotherapy and received EMP monotherapy (560 mg/day) at 2 institutions from 2008to 2017. We analyzed prostate-specific antigen (PSA) responses, overall survival, and adverse effects of EMPtreatment. Results: A total of 28 patients were analyzed. A reduction in serum PSA was observed in 11 patients (39.3%).Seven cases (25.9%) achieved more than 25% reduction of PSA, and 5 of them (18.5%) experienced more than50% reduction. Median overall survival was 23 months (interquartile range, 10–60 months). Multivariable analysesdemonstrated that low level of PSA at diagnosis of CRPC and long duration of prior androgen deprivation therapywere independent favorable factors predicting long-term overall survival. Adverse effects were edema (n=2; grade2), nausea/vomiting (n=1; grade 2), gynecomastia (n=1; grade 2), and dyspnea (n=1; grade 1). Neither thromboembolicevent nor grade 3–5 toxicity was observed. There was no discontinuation caused by side effects ofEMP. Conclusions EMP monotherapy could be considered as a safe treatment option with some effectiveness for CRPCpatients who did not undergo cytotoxic chemotherapy. EMP is not generally recommended anticancer drug in thecurrent guidelines for CRPC, but EMP monotherapy is thought to have an alternative role when a standard treatmentcannot be selected due to patient's age, health condition, or comorbidity.

OBJECTIVE: Pralidoxime is widely used for the treatment of organophosphate poisoning. Multiple studies have reported its vasoconstrictive property, which may facilitate the restoration of spontaneous circulation (ROSC) after cardiac arrest by increasing the coronary perfusion pressure (CPP). 2,3-Butanedione monoxime, which belongs to the same oxime family, has been shown to facilitate ROSC by reducing left ventricular ischemic contracture. Because pralidoxime and 2,3-butanedione monoxime have several common mechanisms of action, both drugs may have similar effects on ischemic contracture. Thus, we investigated the effects of pralidoxime administration during cardiopulmonary resuscitation in a pig model with a focus on ischemic contracture and CPP.METHODS: After 14 minutes of untreated ventricular fibrillation, followed by 8 minutes of basic life support, 16 pigs randomly received either 80 mg/kg of pralidoxime (pralidoxime group) or an equivalent volume of saline (control group) during advanced cardiovascular life support (ACLS).RESULTS: Mixed-model analyses of left ventricular wall thickness and chamber area during ACLS revealed no significant group effects or group-time interactions, whereas a mixed-model analysis of the CPP during ACLS revealed a significant group effect (P=0.038) and group-time interaction (P<0.001). Post-hoc analyses revealed significant increases in CPP in the pralidoxime group, starting at 5 minutes after pralidoxime administration. No animal, except one in the pralidoxime group, achieved ROSC; thus, the rate of ROSC did not differ between the two groups.CONCLUSION: In a pig model of cardiac arrest, pralidoxime administered during cardiopulmonary resuscitation did not reduce ischemic contracture; however, it significantly improved CPP.

PURPOSE: Overcrowding in urban emergency departments (EDs) while a decline in rural EDs due to mismatch of supply and demand of emergency medical resources are still issues to date. Therefore, this study analyzed the current characteristics and reality of bed utilization in the EDs of Korea. METHODS: Real-time availability of bed information was obtained from the emergency medical resource information system. The data were extracted for 4 weeks every 3 months, from April 2014 to January 2015. We analyzed the emergency department utilization (EDU) rate of emergency medical centers and hospitals based in 16 provinces in Korea. RESULTS: A total of 14,889,750 data were included. The total EDU rate was 20.0% (9.1-43.9%). The EDU rate was 66.7% (40.0-95.0%) for regional emergency medical centers (REMC), 33.3% (15.0-63.3%) for local emergency medical centers (LEMC), 11.1% (0.0-30.0%) for local emergency medical agencies (LEMA). The EDU rate was 71.4.0% (50.0.0-96.7.0%) for tertiary general hospitals (TGH), 20.0% (10.0-36.8%) for general hospitals (GH), and 10.0% (0-20.0%) for hospital & medical centers (HMC). The REMC EDU rate was high in Seoul and Jeonbuk, and low in Jeonnam and Gyeongbuk. The LEMC utilization rate was high in Daegu and Jeonbuk. The LEMA utilization rate was high in Daegu and Ulsan. Moreover, despite the same ED type, the EDU rate of high degree hospitals was higher. CONCLUSION: The EDU rate differed by region, emergency medical center, and hospital type. We should consider investing in appropriate personnel and emergency medical resources in places with suboptimal EDU rate.

Prostate cancer is the most common type of male cancer worldwide. Although radical prostatectomy (RP) is advised for prostate cancer in patients with a life expectancy of more than 10 years by various guidelines, most elderly men still do not undergo the procedure regardless of increasing life expectancy. This study aimed to determine whether RP is suitable for patients with prostate cancer aged 75 years or older. A retrospective study of patients who underwent RP at 6 institutions between 2005 and 2012 was conducted. Patients were divided into 2 groups at the time of surgery: 65-69 years (younger group) and 75 years or older (older group). We compared clinical characteristics, pathological results, complication rates, and recurrence-free survival between the two groups. Compared with the younger group, the older group had significantly higher preoperative serum prostate-specific antigen level, pre- and postoperative Eastern Cooperative Oncology Group (ECOG) performance status grade, hypertension prevalence, and Gleason score at biopsy and RP. However, except urinary incontinence, there were no statistically significant differences in the peri- and post-operative complications. After median follow-up periods of 36 months (younger group) and 40 months (older group), the biochemical recurrence-free survival rates were not significantly different (P = 0.581). Although the urinary incontinence rate was higher in the older group, RP was a suitable option for selected Korean men aged 75 years or older with limited complication rates and excellent outcomes similar to those for patients aged 65-69 years.

PURPOSE: Climacturia is involuntary loss of urine during orgasm. The mechanism of climacturia in men who undergo radical prostatectomy (RP) is not fully understood, while deficiency in bladder neck coaptation during orgasm may be the cause. We evaluated the prevalence and risk factors of climacturia after RP. MATERIALS AND METHODS: We retrospectively reviewed the medical records of prostate cancer patients who underwent RP from 2002 to 2013 and was able to have a vaginal intercourse postoperatively. RP was conducted using open or robot-assisted approach. We analysed the symptoms of climacturia, relationship between climacturia and several clinical factors. Also, we tried to find factors to predict the presence of climacturia. RESULTS: Total of 123 patients were analyzed in this study. The median age of the men was 65 year and postoperative follow-up period for the interview was 37 months. Of the total 123 patients, 29 (23.6%) complained of the climacturia. In climacturia group, robot-assisted RP (p=0.018), nerve-sparing (p=0.046) and penile rehabilitation (p=0.012) were significantly less frequent, and more pad were comsumed (p=0.001) compared to non-climacturia group. On multivariable analysis, post-prostatectomy incontinence (PPI) (OR 6.49, p=0.004) and penile rehabilitation (OR 0.22, p=0.036) were significant factors to predict the presence of climacturia. CONCLUSIONS: Climacturia occurs in more than 20% patients who were potent enough after RP in our study. PPI and penile rehabilitation were positive and negative factor to predict an occurrence of climacturia, respectively. Therefore, in addition to PPI and erectile dysfunction, patients must be informed of this complication before undergoing RP.

PURPOSE: Studies to determine the relation between oxygen tension and outcome in cardiac arrest survivors treated with therapeutic hypothermia (TH) are lacking. We investigated the relation of time-weighted mean oxygen tension (TWMO2) and outcome in cardiac arrest survivors treated with TH. METHODS: This was a retrospective observational study including 177 out-of-hospital cardiac arrest (OHCA) survivors. The patients were divided into four categories according to quartile values of TWMO2. The primary outcome was neurologic outcome at discharge and the secondary outcome was all cause in-hospital mortality. We assessed neurologic outcome using the Cerebral Performance Categories (CPC) at hospital discharge. Neurologic outcome was dichotomised as either good neurologic outcome (CPC1 and CPC2) or poor neurologic outcome (CPC 3 to 5). The odds ratio with 95% confidence interval (CI) was estimated. RESULTS: The median value of PaO2 was 139(104.5-170.0) mmHg. Among a total of 1,239 PaO2 values, 22(1.8%) values were hypoxia (<60 mmHg) and 16(1.3%) values were hyperoxia (>300 mmHg). Results of univariate logistic regression analysis showed a significantly low odds ratio for poor neurologic outcome [0.353(95% CI, 0.133-0.938) and 0.321(95% CI, 0.121-0.850), respectively] and for in-hospital mortality [0.338(95% CI, 0.132-0.870) and 0.387(95% CI, 0.154-0.975), respectively] for the third quartile and the fourth quartile. However, results of multivariate logistic regression analysis showed no significant relation between TWMO2 and outcomes. CONCLUSION: In OHCA survivors treated with TH, time-weighted oxygen tension did not show an association with neurologic outcome and in-hospital mortality.

PURPOSE: Therapeutic hypothermia (TH) improves the probability of survival and neurologic recovery after resuscitation from out-of-hospital cardiac arrest (OHCA). However, the best time to initiate TH after the return of spontaneous circulation (ROSC) remains unknown. METHODS: The aim of this study was to evaluate the correlation between TH initiation time after ROSC and the resulting neurological outcome. Methods: A retrospective analysis was performed on 122 OHCA patients enrolled between January 2008 and December 2011. Therapeutic hypothermia (32~34degrees C) was induced immediately after ROSC. The primary measure of outcome was neurological function at hospital discharge, as determined by a cerebral performance category (CPC) scale. RESULTS: Out of the 122 patients, 34 patients (27.9%) had a good neurological outcome at hospital discharge. The initiation time following ROSC was shorter, although not statistically significant, in patients with good neurological outcomes compared to those with poor outcomes. Based on subgroup analysis, only the shockable rhythm group showed a significant difference, in the time after ROSC to TH initiation, between good and poor neurological outcome groups. Receiver operator characteristic analysis suggested that an initiation time of 250 min after ROSC was most predictive of CPC 1-2 outcomes compared to other time points. Furthermore, the 250 min initiation time after ROSC correlated with neurological outcome in patients with OHCA undergoing TH treatment. CONCLUSION: Compared to late initiation, early initiation (within 250 min) with TH had neurologic benefits for patients with OHCA.

PURPOSE: The association of serial serum cholinesterase (SChE) activity and the occurrence of intermediate syndrome (IMS) in patients orally poisoned with organophosphate (OP) were investigated. In addition, other clinical and laboratory factors were assessed for their ability to predict the subsequent development of IMS. METHODS: A total of 114 patients presented to our emergency department with acute OP ingestion between 2007 and 2012 were enrolled in this prospective study. Of these patients, 67 who needed mechanical ventilation (MV) over five days were divided into the IMS group. The 47 patients weaned from MV within four days after admission, or who did not receive the assistance of MV, were placed in the non-IMS group. The level of SChE at admission, 48 hours, and 96 hours, at discharge after admission were checked. The APACHE II (Acute Physiology, Age, Chronic Health Evaluation II) score, the amount ingested, exposure route, gender, age, and the laboratory test results were collected. All statistical analyses were performed using the Statistical Package for the Social Sciences (version 20.0). RESULTS: The mean age of total enrolled patients was 53.7+/-17.9 years and 73 patients (64.0% of total patients) were male. There were 102(89.5%) patients who intentionally ingested the OP and the mean amount ingested was 102.5+/-64.9 mL. The mean time after patients sought medical care was 5.4+/-10.5 hours after ingestion. The level of SChE at admission was 1,586+/-796 U/L and the APACHE II score was 28.81+/-19.7. The arterial pH, bicarbonate and carbon dioxide pressure, and serum protein and albumin were significantly lower in the IMS group than the non-IMS group (p<0.001). In contrast, the serum amylase, lipase, and glucose were higher in the IMS group. The APACHE II score, serum albumin and amylase, arterial bicarbonate, and the SChE at 48 and 96 hours after ingestion were independent factors that predicted the occurrence of IMS in patients with OP poisoning. The rate of recovery was 86.6% in the IMS group and 100% in the non-IMS group (p<0.001). CONCLUSION: Patients with a higher APACHE II score and levels of serum amylase, and lower levels of serum albumin and arterial bicarbonate, may be associated with the occurrence of IMS. Furthermore, when SChE levels after 48 hours and 96 hours did not increase, compared with the level of SChE at admission, patients tended to show IMS.
