연구배경: 1978년 란셋 잡지에 보라색 소변에 대한 보고가 최초로 있은 이래, 이 현상에 대한 생화학적, 미생물학적, 임상적 규명이 있었다. 보라색 소변은 환자나 환자 가족에게 불편하거나 걱정스러운 질병이다. 그러나 대개의 경우 환자의 건강에 실제적인 위험이 되는 경우는 거의 없다. 심지어 보라색 소변은 열심히 치료할 필요가 없다고 주장하는 사람도 있다. 이에 대조군 연구를 통하여 보라색 소변의 위험요인과 임상적인 의미(심각성)에 대하여 평가를 하고자 한다. 방법: 2007년 2월부터 4월 사이에 인천은혜병원에 입원하고 있는 381명의 환자들 중 도뇨관을 삽입하고 있는 65명을 대상으로 하였다. 이 65명은 65세 이하이거나 1개월 이하동안 도뇨관을 갖고있는 환자는 제외한 숫자이다. 대상 환자는 모두 실리콘제의 폴리카테터와 일회용 소변주머니를 사용하였고 카테터의 교환주기는 특별한 경우 외에는 1개월마다 교환하였다. 대상환자 중 16명이 보라색 소변을 보여, 멸균생리식염수로 방광세척을 한 뒤 카테터와 소변 주머니를 소독된 새 것으로 무균적으로 교환한 뒤 소변배양을 실시하였다. 관련 환자와 대조군의 비교항목들을 통계처리하여 통계적인 유의성을 확인하였으며, 변수의 분석은 신뢰도 95%로(P value 0.05) 카이스퀘어 가설검정과 만-휘트니 U검사를 실시하였다. 결과: 보라색 소변을 보였던 환자들의 나이 평균은 80세였고 전원이 와상상태의 할머니였다. 대상환자의 진단명 중 가장 많은 것은 치매였다. 평균 도뇨기간은 22개월 이었다. 보라색소변을 보인환자군은 보이지 않은 환자들 보다 평균 도뇨기간이 길었으며, 변비가 더 심하였고 변비치료용 좌약 사용빈도가 높았다. 대조군에서는 조사기간 전 1개월 이내에 항생제를 사용한 빈도가 약간 더 높았으나 통계적인 의미는 확실하지 않았다. 결론: 보라색소변은 장기요양노인병원에서 흔히 발생하는 문제이다. 이전 연구들에서 없었던 보라색 소변과 항생제사용과의 관련성 및 변비치료제로 bisacodyl 좌약사용과의 관련성, 소변 카테터의 삽입기간 등에 대한 정보를 추가하여 얻을 수 있었다. Background: Since the first report of purple urine bag syndrome (PUBS) by Barlow and Dickson in 1978, many researchers have tried to reveal the clinical and bacteriological background of this phenomenon. To the best of our knowledge, most of them were case or case series reports and only three were case-control studies which compared the clinical, biochemical, or bacteriological background between patients with and without PUBS. It is certain that PUBS is an uncomfortable or troubling issue for some patients and their families. However, most of the patients who presented with PUBS were, largely, asymptomatic and it is apparent that PUBS is not a disease per se, nor does it appear to represent any real danger to patient's health, and some authors go so far as to even advocate that it is unnecessary to treat PUBS-affected patients aggressively. In this case-control study, we reviewed risk factors and clinical significance of PUBS in geriatric wards. Methods: Of the 381 hospitalized patients in a hospital specialized in the long term care of the elderly handicapped (Incheon Eun-Hye Hospital, Incheon, Korea), 65 patients who featured urinary catheterization during the period from February 2007 and April 2007 were enrolled in this study. Subjects who were younger than 65 or catheterized duration was less than one month were excluded. The same types of silicone Foley balloon catheter and disposable plastic urine bag were used for all patients. Routine Foley catheter change interval was one month. For the 16 patients who exhibits PUBS, bladder irrigation with normal saline and immediate change of urine bag and catheter were performed. And urine culture was done. Variables were statistically analyzed by chi square test or Mann-Whitney's U-test. P values less than 0.05 were considered statistically significant. Results: The PUBS patients mean age was 80, and bed ridden female. Most common diagnosis was dementia. Mean duration of the catheterization was 22 months. The PUBS patients were more constipated than non-PUBS control group and used more bisacodyl suppository. Antibiotics usage within one month before this survey in PUBS group is more frequent than control group with borderline statistical significance. Conclusion: PUBS is frequently occurring problem in long-term care geriatric wards. Causative factors are tryptophan putrefaction (decreased intestinal absorption, motility), alkaline urine, oxygen (air, Foley catheterization). All factors are bacterial infection related. Our results were the same as previous results. Relationship with antibiotics usage, bisacodyl suppository and constipation, long term usage of the Foley catheter notified also. Female predomination is related with easy, frequent urinary infection, and more population in old age.

Background/Aims: Trends in successful eradication of Helicobacter pylori using first-line triple therapy, consisting of a proton pump inhibitor, amoxicillin, and clarithromycin, have been understudied. We evaluated H. pylori eradication rates at a single center over the last 10 years and identified risk factors related to eradication failure. Methods: This study included 1,413 patients who were diagnosed with H. pylori infection and received 7 days of triple therapy between January 2003 and December 2012. We investigated H. pylori eradication rates retrospectively with respect to the year of therapy, as well as demographic and clinical factors. H. pylori eradication was confirmed by a 13C-urea breath test or a rapid urease test at least 4 weeks after the completion of triple therapy. Results: The overall H. pylori eradication rate was 84.9%. Annual eradication rates from 2003 to 2012 were 93.5%, 80.0%, 87.2%, 88.5%, 92.0%, 88.3%, 85.7%, 84.1%, 83.7%, and 78.8%, respectively, by per-protocol analysis. The eradication rate with first-line triple therapy decreased during the last 10 years (p = 0.015). Multivariate analysis showed that female gender (odds ratio [OR], 1.69; 95% confidence interval [CI], 1.12 to 2.55) and smoking (OR, 1.61; 95% CI, 1.05 to 2.47) were associated with the failure of H. pylori eradication therapy. Conclusions: The efficacy of first-line triple therapy for H. pylori infection has decreased over the last 10 years, suggesting an increase in antibiotic-resistant H. pylori strains. Thus, other first-line therapies may be necessary for H. pylori eradication in the near future.

Purpose: To investigate the clinical outcome of proton therapy (PT) in patients with chordoma. Materials and Methods: Fifty-eight patients with chordoma treated with PT between June 2007 and December 2015 at the National Cancer Center, Korea, were retrospectively analyzed. The median total dose was 69.6 cobalt gray equivalent (CGE; range, 64.8 to 79.2 CGE). Local progression-free survival (LPFS), distant metastasis-free survival (DMFS), overall survival (OS), and diseasespecific survival (DSS) rates were calculated by the Kaplan - Meier method. Results: With the median follow-up of 42.8 months (range, 4 to 174 months), the 5-year LPFS, DMFS, OS, and DSS rates were 87.9%, 86.7%, 88.3%, and 92.9%, respectively. The tumor location was associated with the patterns of failure: the LPFS rates were lower for cervical tumors (57.1%) than for non-cervical tumors (93.1%) (p = 0.02), and the DMFS rates were lower for sacral tumors (53.5%) than for non-sacral tumors (100%) (p = 0.001). The total dose was associated with both the LPFS rate and DMFS rate. The initial tumor size was associated with the DMFS rate, but was not associated with the LPFS rate. Three patients had grade 3 late toxicity with none ≥grade 4. Conclusion: PT is an effective and safe treatment in patients with chordomas. The tumor location was associated with the patterns of failure: local failure was common in cervical tumors, and distant failure was common in sacral tumors. Further refinement of PT, such as the utilization of intensity modulated PT for cervical tumors, is warranted to improve the outcome.

A benign pulmonary metastasizing leiomyoma is a recognized clinical entity that has been infrequently reported in the medical literature. We report two cases of a benign pulmonary metastasizing leiomyoma. A 35-year-old woman who underwent myomectomy and a cesarean section approximately 6 years earlier visited our hospital for further evaluation of incidentally revealed multiple lung nodules. A diagnostic percutaneuous biopsy was performed. Finally she was diagnosed with a benign metastasizing leiomyoma. The patient then received LH-RH and has been followed up since. The other 44-year-old woman presented after an initial radiology evaluation revealed the presence of multiple, small-sized lung nodules. She underwent a right middle lung wedge resection to confirm the diagnosis. Finally she diagnosed with a benign metastasizing leiomyoma. The multiple lung nodules have been followed up closely.

<P><B>Abstract</B></P>Objective: To investigate the neonatal outcomes of twin pregnancies delivered at late-preterm versus term gestation based on chorionicity and indication for delivery.Study Design: This is a retrospective cohort study of women with twin pregnancies delivered at ≥34 weeks of gestation from 1995 to 2014. Subjects were categorized into two groups according to gestational age at delivery: late-preterm group (34–36 weeks) and term group (≥37 weeks). Neonatal outcome measures including neonatal intensive care unit (NICU) admission, mechanical ventilator support, and respiratory distress syndrome (RDS) were compared between the late-preterm and term group based on chorionicity (monochorionic or dichorionic) and delivery indication (elective or non-elective).Results: A total of 1198 twin pregnancies were included in the study: 679 in the late-preterm group and 519 in the term group. Late-preterm twin infants had higher rates of NICU admission, mechanical ventilator support, and RDS than did term twin infants, regardless of the chorionicity and indication for delivery. In the multivariable analysis, late-preterm birth, monochorionicity, and non-elective delivery were independently associated with a significantly higher risk of NICU admission and mechanical ventilator support.Conclusion: The late-preterm birth was associated with a higher risk of adverse neonatal outcome regardless of chorionicity and indication for delivery, and showed significantly increased risk by monochorionicity and non-elective delivery.
