BACKGROUND: Despite prophylactic preoperative managements, surgical site infection (SSI) still has a significant influence on the mortality and morbidity of surgical patients because of an increased number of immunocompromised patients, prolonged anesthesia or an increased use of various operative equipments. In the end, it leads to an increase in hospital days and medical expenses. Therefore, we tried to find out significant risk factors for SSI in a general hospital. METHODS: The study was carried out on the 1,239 patients who underwent a surgical operation in a general hospital, and the incidence rate and risk factors of SSI were analyzed. RESULTS: Among the 1,239 patients, 33 (2.7%) had SSI and the incidence rate was 26.6 per 1,000 person. Of these, 27 (81.8%) and 6 (18.2%) developed an infection before and after discharge, respectively. The influencing factors of SSI were the dirty wound, the frequency of re-operation, the duration of preoperative hospitalization, and the duration of the operation. The most common pathogen isolated from the surgical site was Staphylococcus aureus (27.2%). CONCLUSION: To prevent SSI, a professional group must be established to manage surgical sites and wounds, and the patients should be covered by strict standardized knowledge and guidance.

PURPOSE: The purpose of this study was to determine the impact of uncertainty and uncertainty appraisal on quality of life (QoL) among prostate cancer patients after prostatectomy. METHODS: A descriptive correlational study was conducted with 117 participants at a hospital in S city from October 1 to December 31, 2016. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression using the IBM SPSS/WIN 21.0 program. RESULTS: According to a multiple regression model of the factors affecting QoL among prostate cancer patients after the operation, 61% of variance (F=13.92, p<.001) was explained by metastasis, recurrence, monthly income, uncertainty, uncertainty danger appraisal, and uncertainty opportunity appraisal. And the most influential factor in the QoL was uncertainty danger appraisal (β=-.37, p<.001). CONCLUSION: This study demonstrated that QoL was influenced by uncertainty, uncertainty appraisal and personal characteristics. Prostate cancer patients following prostatectomy should be provided with tailored training to improve their uncertainty opportunity appraisal. Also the educational program for reducing their uncertainty should be developed and provided to patients.

PURPOSE: The purpose of this study was to determine the factors that influence healthcare providers' attitude towards end-of-life care (EOLC) in the emergency department (ED) in hospital settings. METHODS: From June 1 through June 30, 2014, a descriptive correlational study was performed with 41 doctors and 105 nurses stationed in the ED. RESULTS: According to a regression model on the factors affecting healthcare providers' professional attitude towards EOLC, 28.1% of variance (F=15.185, P=0.000) was explained by awareness of death, gender and personal attitude towards EOLC. And 34.1% of the healthcare providers' personal attitude was related with awareness of death, experience of hospice education, occupations and professional attitude towards EOLC. CONCLUSION: This study demonstrated that attitude towards EOLC was influenced by awareness of death and personal characteristics. Healthcare providers in the ED should be provided with tailored training to improve their understanding of death. Also an educational program should be developed and provided to ED healthcare providers to improve their awareness of death.

PURPOSE: Whole breast irradiation (WBI) after breast conserving surgery (BCS) is the standard treatment modality for controlling ipsilateral local recurrence of breast cancer. However, the WBI needs 5 to 6 weeks of the treatment period. Partial breast irradiation (PBI) has recently appeared as an alternative treatment to WBI in selected early breast cancer patients. This study was performed to evaluate the feasibility of PBI alone after BCS. METHODS: The brachy-catheters were inserted at the lumpectomy site after BCS. Six to nine days after the operation, the patients underwent fractionated PBI twice in a day with median dose of 3 Gy. The median value of the total dose was 3,120 cGy (28 to 34 Gy) given over 5 days. Forty-one patients who were proven as having a tumor-free margin by pathologic report were included in this study. Thirty-five patients had axillary lymph node-negative disease and thirty- six patients underwent concurrent adjuvant CMF chemotherapy. Follow-up ultrasono graphy was performed one month after the completion of PBI. RESULTS: The median post-operative hospital stay was 15 days (range: 12-17 days). Twenty-eight patients had seromas smaller than 1 cm in size and the 13 patients appeared to have 1~3 cm sized seromas on the follow-up ultrasonography. Long lasting (> 3 months) seromas were observed in 7 patients. None of the patients complained of tenderness or discomfort of the operation site and complications such as skin desquamation, pigmentation and wound contracture were not observed. Fat necrosis was observed in 1 patient. There was no case of local recurrence at the median follow-up period of 19 months (range: 15-41 months). CONCLUSION: PBI for early breast cancer using interstitial brachytherapy was a safe and effective alternative to WBI with excellent cosmetic results after BCS. The results of the current study prompts a multi-center clinical trial of PBI as an alternative to the WBI in early breast cancer to validate its feasibility in a selected patient population.

PURPOSE: Peritoneal dialysis (PD) catheter removal is regarded as an important index of patient morbidity. The aim of this study was to evaluate factors influencing catheter loss following peritonitis in PD patients. METHODS: We retrospectively reviewed 917 episodes of peritonitis in 621 new CAPD patients from Jan 2001 to Feb. 2009 in Dongsan Medical center. Episodes requiring PD catheter removal were compared by both univariate and multivariate analyses with those in which PD catheters were preserved. RESULTS: When peritonitis episodes requiring PD catheter removal (n=80) were compared to catheter preserved peritonitis episodes (n=837), the incidence of PD catheter loss increased as the duration on PD preceding the peritonitis were longer (p<0.000). Also, PD catheter removal was more likely to occur after peritonitis episodes with low serum albumin level (p=0.009) and high serum CRP level (p<0.000), those with long duration of PD effluent leukocyte count remaining above 100/mm3 (p<0.000), those with concomitant exit site/tunnel infection (p=0.043), and those with presence of abdominal pathology (p<0.000). The microbiological determinants of PD catheter loss included two or more bacteria cultured (p=0.002) and fungi (p<0.000). In multivariate analysis, the duration of PD effluent leukocyte count remaining above 100/mL and the number of organism cultured were independent risk factors of PD catheter removal in peritonitis episodes. CONCLUSION: Duration of PD effluent leukocyte count remaining above 100/mm3, and the number of organisms cultured were independent risk factors for catheter removal following peritonitis.

Objective: We aimed to compare the aortic valve area (AVA) calculated using fast high-resolution three-dimensional (3D) magnetic resonance (MR) image acquisition with that of the conventional two-dimensional (2D) cine MR technique. Materials and Methods: We included 139 consecutive patients (mean age ± standard deviation [SD], 68.5 ± 9.4 years) with aortic valvular stenosis (AS) and 21 asymptomatic controls (52.3 ± 14.2 years). High-resolution T2-prepared 3D steady-state free precession (SSFP) images (2.0 mm slice thickness, 10 contiguous slices) for 3D planimetry (3DP) were acquired with a single breath hold during mid-systole. 2D SSFP cine MR images (6.0 mm slice thickness) for 2D planimetry (2DP) were also obtained at three aortic valve levels. The calculations for the effective AVA based on the MR images were compared with the transthoracic echocardiographic (TTE) measurements using the continuity equation. Results: The mean AVA ± SD derived by 3DP, 2DP, and TTE in the AS group were 0.81 ± 0.26 cm2 , 0.82 ± 0.34 cm2 , and 0.80 ± 0.26 cm2 , respectively (p = 0.366). The intra-observer agreement was higher for 3DP than 2DP in one observer: intraclass correlation coefficient (ICC) of 0.95 (95% confidence interval [CI], 0.94–0.97) and 0.87 (95% CI, 0.82–0.91), respectively, for observer 1 and 0.97 (95% CI, 0.96–0.98) and 0.98 (95% CI, 0.97–0.99), respectively, for observer 2. Inter-observer agreement was similar between 3DP and 2DP, with the ICC of 0.92 (95% CI, 0.89–0.94) and 0.91 (95% CI, 0.88–0.93), respectively. 3DP-derived AVA showed a slightly higher agreement with AVA measured by TTE than the 2DP-derived AVA, with the ICC of 0.87 (95% CI, 0.82–0.91) vs. 0.85 (95% CI, 0.79–0.89). Conclusion High-resolution 3D MR image acquisition, with single-breath-hold SSFP sequences, gave AVA measurement with low observer variability that correlated highly with those obtained by TTE.

BACKGROUND/AIMS: Several studies have suggested that surgical resection (SR) can provide a survival benefit over transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) at the intermediate stage according to the Barcelona Clinic Liver Cancer (BCLC) staging system. However, the criteria for SR remain to be determined. This study compared the long-term outcome of intermediate-stage HCC patients treated by either TACE or SR as a primary treatment modality, with the aim of identifying the patient subgroup that gained a survival benefit by either modality. METHODS: In total, 277 BCLC intermediate-stage HCC patients treated by either TACE (N=225) or SR (N=52) were analyzed. RESULTS: The overall median survival time was significantly better for SR than TACE (61 vs. 30 months, P=0.002). Decision-tree analysis divided patients into seven nodes based on tumor size and number, serum alpha-fetoprotein (AFP) level, and Child-Pugh score, and these were then simplified into four subgroups (B1-B4) based on similarities in the overall hazard rate. SR provided a significant survival benefit in subgroup B2, characterized by ‘oligo' (2-4) nodules of intermediate size (5-10 cm) when the AFP levels was <400 ng/ml, or ‘oligo' (2-4) nodules of small to intermediate size (<10 cm) plus a Child-Pugh score of 5 when the AFP level was ≥400 ng/mL (median survival 73 vs. 28 months for SR vs. TACE respectively; P=0.014). The survival rate did not differ significantly between SR and TACE in the other subgroups (B1 and B3). CONCLUSIONS: SR provided a survival benefit over TACE in intermediate-stage HCC, especially for patients meeting certain criteria. Re-establishing the criteria for optimal treatment modalities in this stage of HCC is needed to improve survival rates.
