Background: The purpose of this study was to determine the benefit of tertiary cytoreductive surgery (TC) for secondary recurrent epithelial ovarian cancer (EOC), focusing on whether optimal cytoreduction has an impact on disease-free survival, and whether certain patient characteristics could identify ideal candidates for TC. Materials and Methods: Retrospective analysis of secondary recurrent EOC patients undergoing TC at three Turkish tertiary institutions from May 1997 to July 2014 was performed. All patients had previously received primary cytoreduction followed by intravenous platinum-based chemotherapy and secondary cytoreduction for first recurrence. Clinical and pathological data were obtained from the patients' medical records. Survival analysis was caried out using the Kaplan Meier method. Actuarial curves were compared by the two tailed Logrank test with a statistical significance level of 0.05. Results: Median age of the patients was 49.6 years (range, 30-67) and thirty-eight (72%) had stage III-IV disease at initial diagnosis. Twenty six (49%) had optimal and 27 (51%) suboptimal cytoreduction during tertiary debulking surgery. Optimal initial cytoreduction, time to first recurrence, optimal secondary cytoreduction, time interval between secondary cytoreduction and secondary recurrence, size of recurrence, disease status at last follow-up were found to be significant risk factors to predict optimal TC. Optimal cytoreduction in initial and tertiary surgery and serum CA-125 level prior to TC were independent prognostic factors on univariate analysis. Conclusions: Our results and a literature review clearly showed that maximal surgical effort should be made in TC, since patients undergoing optimal TC have a better survival. Thus, patients with secondary recurrent EOC in whom optimal cytoreduction can be achieved should be actively selected.

Objective: We evaluated the clinical characteristics and prognoses of patients with septic shock who transferred to the emergency department (ED) in a tertiary referral center. Methods: This study was performed using a prospective, multi-center registry of septic shock, with the participation of 11 tertiary referral centers in the Korean Shock Society between October 2015 and February 2017. We classified the patients as a transferred group who transferred from other hospitals after meeting the inclusion criteria upon ED arrival and a non-transferred group who presented directly to the ED. Primary outcome was hospital mortality. We conducted multiple logistic regression analysis to assess variables related to in-hospital mortality. Results: A total of 2,098 patients were included, and we assigned 717 patients to the transferred group and 1,381 patients to the non-transferred group. The initial Sequential Organ Failure Assessment score was higher in the transferred group than the non-transferred group (6; interquartile range [IQR], 4-9 vs. 6; IQR, 4-8; P<0.001). Mechanical ventilator (29% vs. 21%, P<0.001) and renal replacement therapy (12% vs. 9%, P=0.034) within 24 hours after ED arrival were more frequently applied in the transferred group than the non-transferred group. Overall hospital mortality was 22% and there was no significant difference between transferred and non-transferred groups (23% vs. 22%, P=0.820). Multivariable analysis showed an odds ratio for in-hospital mortality of 1.00 (95% confidence interval, 0.78-1.28; P=0.999) for the transferred group compared with the non-transferred group. Conclusion: The transferred group showed higher severity and needed more organ support procedures than the non-transferred group. However, inter-hospital transfer did not affect in-hospital mortality.

목적: 최근 미숙아에서 동맥관 결찰 술 후 설명할 수 없는 혈역동학적 불안정성에 대한 보고가 되고 있어 극소저체중아에서 동맥관 결찰술 후 발생하는 혈역동학적 불안정성의 위험 요인 및 임상 양상에 대해 알아보고자 하였다. 방법: 2002년 1월부터 2008년 12월까지 고려대학교 의료원내 3개 병원의 신생아 중환자실에서 치료 받은 재태 32주 미만의 극소저체중출생아에서 동맥관 결찰술을 시행 받은 환아 18명을 대상으로 하여 의무기록을 후향적으로 조사, 분석하였다. 수술 중 또는 수술 후 문제로 인한 혈역동학적 불안정성 이외에 설명할 수 없는 심폐 기능의 저하로 인공 호흡기 의존도의 증가와 혈압의 하강 등이 관찰된 환자를 혈역동학적 불안정군(hemodynamic instability group, HI)으로 정의하였다. 결과: 연구에 참여한 18명의 환아들의 재태 주수는 $27^{+6}{\pm}1^{+6}$주, 평균 출생 체중은 951${\pm}$245 g이었다. HI군은 7명(7/18, 39%)이었으며 혈역동학적 안정군(hemodynamic stability group, HS)은 11명(11/18, 61%)이었다. HS군에 비해 HI군은 출생 체중(1,033${\pm}$285 g vs. 821${\pm}$126 g, P=0.048)과 수술 시 체중(1,195${\pm}$404 g vs. 893${\pm}$151 g, P=0.042)이 작았으며, 재원기간이 길었고 (105${\pm}$29 vs. 141${\pm}$39, P=0.038) 심한 기관지 폐 이형성증의 빈도가 높았고(no/mild/moderate/severe, 2/5/2/2 vs. 0/1/2/4, P=0.038) 수술 전 $FiO_2$의 농도가 높았다(0.29${\pm}$0.06 vs. 0.38${\pm}$ 0.09, P=0.02). 18명 중 HS군에서 1명의 환아가 동맥관 결찰술 후 94일 째 패혈증으로 사망하였다. 결론: 극소저체중아에서 동맥관 결찰술 후 혈역동학적 불안 정성이 발생한 경우는 약 39%였다. 작은 출생 체중과 수술 시 체중, 수술 전 높은 산소 분압의 산소 투여가 동맥관 결찰술 후 혈역동학적 불안정성 발생의 위험인자가 될 수 있으며 아울러 혈역동학적 불안정성은 기관지 폐 이형성증의 유병률 및 중증도와 재원기간을 증가시킬 수 있음을 확인하였다.

Background/Aims: The aim of this study was to analyze the trend of the prevalences of atrophic gastritis (AG) and intestinal metaplasia (IM) from 2011 to 2016~2017 in Korea. And, the risk factors of AG and IM were compared between 2011 and 2016~2017. Materials and Methods: A total of 4,023 subjects in 2011 and 2,506 subjects in 2016~2017 were enrolled. AG and IM were diagnosed on the basis of endoscopic findings. Multivariate analysis was performed for risk factors of AG and IM. Seventeen factors were analyzed. Results: The seroprevalence of Helicobacter pylori decreased from 2011 (59.8%; 2,407/4,023) to 2016~2017 (51.6%; 1,293/2,506; P<0.001). The prevalence of AG decreased from 2011 to 2016~2017 (P=0.018), but that of IM increased (P<0.001). The risk factors of AG in 2011 were male sex, old age, H. pylori immuoglobulin G (IgG) positivity, family history of gastric cancer (GC), and high-salt diet. For IM in 2011, the risk factors were male sex, old age, H. pylori IgG positivity, and family history of GC. Risk factors of AG in 2016~2017 were old age, H. pylori IgG positivity, and country of residence. For IM in 2016~2017, the risk factors were male sex, old age, family history of GC, high fasting glucose level (${\geq}126mg/dL$), H. pylori IgG positivity, and low income level. Conclusions: The difference in prevalence trends of AG and IM between 2016~2017 and 2011 could be the result of the different risk factors of AG and IM, such as decreased prevalence of H. pylori infection.

목적: 고령 환자의 흉요추부 유합에서 척추경 나사못과 함께 사용된 원위부 갈고리의 임상적 결과를 알아보고자 하였다. 대상 및 방법: 본 연구는 다기관 후향적 연구로, 2008년부터 2015년까지 65세 이상 환자에서 흉요추부 병변으로 전방 지지와 함께 장분절의 후방 유합을 시행한 20명을 대상으로 하였다. 이 중에서 척추경 나사못 및 원위부 갈고리를 이용한 10명을 갈고리 군으로, 원위부 나사못 없이 척추경 나사못만을 이용한 10명을 나사못 군으로 나누어 술 후 1년째 원위부 나사못의 뽑힘 및 후방 이탈의 정도를 비교하였다. 결과: 환자들의 평균 나이는 72.4세(65-83세), 유합 분절은 평균 4.6분절(3-6분절)이었다. 두 군 간의 비교에서 나이, 성별, 원인 질환, 요추 및 근위 대퇴골 골밀도, 골다공증 유무, 유합 분절 수는 두 군 간에 유의한 차이가 없었다(p≥0.05). 술 후 1년 사이에서 발생한 원위부 나사못의 후방 이탈을 평가한 지표는 두 군 간에 유의한 차이가 있었다(p<0.05). 원위부 나사못의 후방 이탈은 총 6명에서 발견되었으며, 이는 모두 원위부 갈고리를 보강하지 않은 나사못 군에서만(60%, 6/10) 관찰되었고 갈고리 군에서는 없었다. 결론: 고령 환자의 흉요추부 장분절 유합에서 원위부 갈고리의 사용은 나사못의 후방 이탈과 관련된 합병증을 막을 수 있는 유용한 술식이다.
