Purpose : Ureteral stent is commonly used after ureterscopic stone removal(URS). However, there is no definitive clinical criteria in inserting the ureteral stent after URS. Patients often complain of bladder irritative symptoms, hematuria. flank pain and additive endoscopic prodedure is neces-sary to remove the ureteral stent. Therefore, we studied the clinical epicacy of selective ureteral stenting only when it is required. Materials and Methods : Of the patients who was taken URS, the following patients were exclu-ded from stent insertion ; 1) Patients who have mild hydronephrosis or symptoms less than 1week. 2) Patients who were able to insert the ureteroscope through the ureteral orifice without difficulty. 3) Patients who hardly have ureteral mucosal damage seen through the ureteroscopic field after the removal of ureteral stone. 4) Patients who did not need the additional lithoclast during the remo-val of ureteral stone. Other than the above patients and those with stones above the mid-ureter, a 6Fr. ureteral stent was inserted and kept for 3weeks. There were 29 unstented patients and 38 stented patients. Results : The average age of the non-stenting and stenting group were 37.5years old and 39.7years old and the average stone size were 0.68cm and 0.80cm. The average operation time was 3 minutes in the non-stenting and 8minutes(including ureteral stent insertion time) in the stenting group. Hos-pital stay was 3days in both groups. Intermittent gross hematuria and irritative symptoms of the bladder was shown for 3weeks after operation in most of the patients(32cases, 84.2%) of the sten-ting group while those in the unstenting group, the symptoms were relieved after2days after operation. Although mild flank pain was shown in few patients(4cases, 13.8%) of the non-stenting group, severe pain requiring intravenous analgesics was not seen in both groups. There were no specific findings in the intravenous urography which was done at 6weeks after operation, and no hematuria and pyuria was found in both groups. Conclusion : The selective placement of ureteral stent following the ureteroscopic removal of stone did not bring specfic complications. We believe that ureteral stent insertion will minimize the inconvenience especially in patients who need to return to their everyday living immediately after operation. Thus ureteral stent insertion should be used in limited situations. 요관경하배석술 후 많은 경우에 있어서 요관부목을 유치하고 잇지만 선별적으로 판단하여 설치할 경우 특별한 문제점이 없었으며, 수술 수 바로 일상생활에 복귀하여야 하는 환자들의 불편함을 최소화할 수 잇을 것으로 생각되며, 요관부목 설치는 제한적인 상황하에서 시행되어야 할 것으로 사료된다.

Lee, Jin Woong,Chae, Sudong,Oh, Seoungbae,Kim, Si Hyun,Choi, Kyung Hwan,Meeseepong, Montri,Chang, Jongwha,Kim, Namsoo,Yong Ho Kim,,Lee, Nae-Eung,Lee, Jung Heon,Choi, Jae-Young American Chemical Society 2018 NANO LETTERS Vol.18 No.12

<P>In this study, Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> single-chain atomic crystals (SCACs) with atomically small chain diameters of ∼0.6 nm, large surface areas, and mechanical flexibility were synthesized and investigated as an extracellular matrix (ECM)-mimicking scaffold material for tissue engineering applications. The proliferation of L-929 and MC3T3-E1 cell lines increased up to 268.4 ± 24.4% and 396.2 ± 8.1%, respectively, after 48 h of culturing with Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> SCACs. More importantly, this extremely high proliferation was observed when the cells were treated with 200 μg mL<SUP>-1</SUP> of Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> SCACs, which is above the cytotoxic concentration of most nanomaterials reported earlier. An ECM-mimicking scaffold film prepared by coating Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> SCACs on a glass substrate enabled the cells to adhere to the surface in a highly stretched manner at the initial stage of cell adhesion. Most cells cultured on the ECM-mimicking scaffold film remained alive; in contrast, a substantial number of cells cultured on glass substrates without the Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> SCAC coating did not survive. This work not only proves the exceptional biocompatible and bioactive characteristics of the Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> SCACs but also suggests that, as an ECM-mimicking scaffold material, Mo<SUB>3</SUB>Se<SUB>3</SUB><SUP>-</SUP> SCACs can overcome several critical limitations of most other nanomaterials.</P> [FIG OMISSION]</BR>

Acquired cystic kidney disease (ACKD), a common complication in patients with end-stage renal disease, is characterized by more than three kidney cysts and normal or decreased sizes of both kidneys without any familial history of cystic kidney disease. In autosomal dominant polycystic kidney disease (ADPKD), however, both kidneys are usually enlarged. Extrarenal manifestations are common in ADPKD, including hepatic cysts, seminal vesicle cysts, mitral valve prolapse. A 40-year-old man presented to the emergency clinic at Inha University Hospital with severe abdominal pain, nausea, and vomiting for 3 days. He had been undergoing continuous ambulatory peritoneal dialysis (CAPD) for 15 years, but it was recently changed to hemodialysis owing to sclerosing encapsulating peritonitis (SEP). Radiologic imaging studies revealed bilateral enlarged kidneys with multiple eggshell calcified cysts and some hepatic cysts, which suggested ADPKD. He underwent left nephrectomy, and pathological tests revealed ACKD-associated renal cell carcinoma (RCC) confined to the resected kidney. He was treated with steroids for SEP, and the symptoms resolved. We herein report a case of ACKD—resembling ADPKD—that progressed to RCC in a patient with concurrent SEP who had been undergoing CAPD for 15 years.

Pancreaticothoracic Fistula Presenting with Hemoptysis and Pneumothorax in a Chronic Alcoholic Patient

Pancreaticothoracic fistula is a rare complication of acute or chronic alcoholic pancreatitis. It may present with various symptoms, like dyspnea, abdominal pain, cough, chest pain, fever, back pain, hemoptysis, fatigue, or orthopnea. Pancreaticothoracic fistula can be detected by magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), or computed tomography. MRCP has high sensitivity and fewer side effects, and thus it has recently been recommended as the first choice for the detection of pancreaticothoracic fistula. On the other hand, ERCP enables the detection and treatment of pancreaticothoracic fistula and allows for stent insertion; for this reason it is a commonly used modality in pancreaticothoracic fistula cases. Herein, the authors describe a case of pancreaticothoracic fistula detected by ERCP and MRCP that manifested only respiratory symptoms, namely hemoptysis and pneumothorax without abdominal pain, which commonly accompanies pancreatitis.

SNS 이용자들의 온라인 구전(eWOM) 행동에 영향을 미치는 요인에 관한연구

이시내(Si Nae Lee),이경렬(Kyung Yul Lee) 한국광고홍보학회 2013 한국광고홍보학보 Vol.15 No.4

본 연구는 SNS상에서 발생하는 온라인 구전의 영향력이 커짐에 따라 SNS 이용자들의 온라인 구전행동에 영향을 미치는 요인들을 규명하고자 하였다. 연구결과 SNS 이용자들은 의견 추구, 의견 제공, 그리고 의견 전달의 세 가지 온라인 구전 유형들 중 의견 전달을 가장 많이 하는 것으로 나타났으며, 그 다음 의견 추구와 의견 제공을 많이 하는 것으로 나타났다. 또한 페이스북 이용자들보다 트위터 이용자들이 온라인 구전행동을 더 적극적으로 취하고 있는 것으로 나타났다. 온라인 구전의 세 가지 유형들 중 의견 전달이 두드러지게 나타난 이유는 트위터처럼 이질적인 배경을 가진 개인 간의 네트워크를 통한 커뮤니케이션이 활발하게 이루어지는 SNS의 특성을 반영한 것으로 보인다. SNS 이용자의 온라인 구전행동에 영향을 미치는 요인들을 살펴본 결과 SNS 이용자들의 온라인 구전행동에 영향을 미치는 요인들은 혁신성, 신뢰성, 규범적 영향, 연결적 사회 자본, 그리고 결속적 사회 자본의 5개의 요인들로 나타났으며, 이들 중 연결적 사회 자본의 영향력이 가장 큰 것으로 나타났다. 또한 페이스북에서는 규범적 영향이 SNS 이용자들의 온라인 구전행동에 가장 큰 영향을 미치는 것으로 나타난 반면에 트위터의 경우 연결적 사회자본이 SNS 이용자들의 온라인 구전행동에 가장 큰 영향을 미치는 것으로 나타났다. 이는 페이스북이 규범적 영향을 많이 받는 친구나 가까운 지인 위주의 동질적 공동체의 유대 형태를 가지고 있는 반면에 트위터는 이질적인 배경을 가진 사람들로 구성된 공동체의 특성을 지니고 있기 때문으로 보인다. The main purpose of this study is to examine the determinants of eWOM behavior of SNS users such as opinion seeking, opinion giving, and opinion passing. The predicting variables include nine factors which are categorized into 4 groups including personal characteristics(innovation, conformity), SNS traits(tie, strength, homophily, trust), interpersonal influence(normative influence, informative influence) and social capital(bridging social capital, bonding social capital) while dependant variable is eWOM behavior of SNS users composed of opinion seeking, opinion giving, and opinion passing. A survey of 400 SNS users was conducted to gather data needed to test research questions. The results of multiple regression analysis showed that 5 predictors out of 9 predictors including innovation, trust, normative influence, bridging social capital, and bonding social capital were statistically related to eWOM such as opinion seeking, opinion giving, and opinion passing. Among those, it turned out that bridging social capital was the best predictor of eWOM behaviors of SNS users, followed by normative influence, bonding social capital, innovation, and trust. The implication of this study is to strengthen these five factors such as bridging social capital, normative influence, bonding social capital, innovation, and trust to activate eWOM of SNS users.
