목 적 : 뇌실 복강간 단락술 부전의 기여인자를 조사 및 분석하여 뇌실 복강간 단락술의 합병증 및 재수술의 가능성을 줄이는 데에 목적이 있다. 대상 및 방법 : 1995년 1월부터 1998년 12월까지 본원에서 뇌실 복강간 단락술을 시행 받은 237명의 수두증 환자를 후향적 방법으로 고찰하여 뇌실 복강간 단락 부전의 기여인자 및 단락기 생존율을 통계학적으로 분석하였다. 결 과 : 수두증의 원인은 종양, 출혈, 감염, 선천성 기형, 정상 뇌압 수두증, 외상 등이었다. 68명의 환자에서 109회의 재수술이 이루어졌다. 재수술의 이유는 폐색, 근위부 카세타의 위치이상, 감염 등이었다. 단락기 생존율은 1년, 2년, 3년에 각각 77.1%, 75.4%, 74.1%이었다. 10세 이하의 환자에서 재수술의 빈도가 통계학적으로 의의 있게 높았다. 그리고 수두증의 원인에 따라서 통계학적으로 의의 있게 재수술의 빈도 차이가 있었다. 결 론 : 대부분의 뇌실 복강간 단락 부전은 술후 1년내에 발생하였다. 환자의 나이 및 수두증의 원인이 뇌실 복 강간 단락 부전의 주요 기여인자였다. To investigate contributory factors of CSF shunt failure, 237 patients, who underwent shunt placement from January 1995 to December 1998 at our hospital, were reviewed retrospectively. The causes of the hydrocephalus were tumor, hemorrhage, infection, congenital anomaly, normal pressure hydrocephalus, trauma and others. One hundred nine revisions of CSF shunting were done during follow up periods. The causes of shunt revisions were mechanical obstruction, malposition, infection and others. The contributory factors of CSF shunt failure and shunt survival rate were analyzed using SPSS. The shunt survival rate at 1, 2 and 3 years after procedure was 77.1%, 75.4%, 74.1% respectively. In the young age group below 10 years old, postinfectous hydrocephalus was the most common high risk factor for shunt revision. In conclusion, the most shunt failures developed in the first year after surgery and the age and causes of the hydrocephalus were major determinant factors of shunt revision.

Background/Aims: Hepatocellular carcinoma (HCC) is common cause of liver related death in Korea, and the importance of alcohol as an etiology of chronic liver disease including cirrhosis is emphasized recently. We investigated the epidemiologic changes of HCC during last 10 years in single tertiary center in Gangneung, Korea. Methods: We retrospectively reviewed the medical records of admitted patients diagnosed as HCC in year 2002 and 2012 respectively, and their clinical characteristics were compared. Results: A total of 214 patients were enrolled. Mean age was 60.1 years and 179 (83.6%) was male. Number of patient with cirrhosis was 160 (74.8%) and with viral hepatitis was 164 (74.8%). Chronic hepatitis B (CHB) was the most common cause of HCC patients with liver cirrhosis (61.9%), and alcohol was 14.4%. The possible curative group (by BCLC stage 0 or A) was only 36.4% (n=78), and had not decreased during the study periods (36.3 % vs. 36.6%, P=0.144), and other clinical variables also had no statistical differences. Conclusions: The clinical characteristics of HCC including clinical stage at the time of diagnosis were not changed over the last 10 year period, and CHB was still the most common etiology of HCC in Gangneung, Korea.

1. CONTENTS<BR> (1) RESEARCH OBJECTIVES<BR> The purpose of this study is to explore the impact of the affordability of ubiquitous home on the satisfaction of the elderly for their lifestyle based on quantitative statistical numerical values.<BR> (2) RESEARCH METHOD<BR> This study analyzes the introduction of the ubiquitous technology to the residential sphere by limiting its focus on the elderly population, which constitutes a group alienated from utilization of information pertaining to livelihood. The study will also pay close attention to the kind of impact such a technology has on the tenants and to the equipment that belongs to the priority application sector. Moreover, to analyze the impact of affordability on the lifestyle satisfaction level, the present study has adopted the multiple regression analysis.<BR> (3) RESEARCH RESULTS<BR> Since the ubiquitous is a technology that has been recently developed and applied, there is a limitation associated with the examination of the satisfaction level of the elderly. It is believed that a sample can be collected from the actual experience of living in a ubiquitous common home after several years from now, and the sample can then be analyzed for a more practical and efficient study,<BR> 2. RESULTS<BR> The study has found that the residential affordability of the ubiquitous for the elderly, who are alienated in terms of the physical and psychological, exerts a notable influence on the lifestyle of the elderly in 6 support areas including convenience, safety, health, sociability, agreeability, and thriftiness but excluding information availability linked with their unfamiliarity with digital devices. Such residential affordability is seen as a positive social change in terms of responding to an aging society.

Increasing antiviral drug resistance, especially multi-drug resistance (MDR) is one of the main problem in the management of chronic viral hepatitis B (CHB). To prevent or treatment of antiviral drug resistance, it should be based on the precise clinical and regular virologic monitoring as well as an early change or add on with drug with higher genetic barrier without sharing cross resistance profile. This topic review will summarize the clinical issues related to antiviral resistance of hepatitis B, including mechanism of resistance, treatment, and prevention strategy.

Positive pressure ventilation (PPV) is one of the most commonly used treatment modalities in the field of neonatology to achieve adequate gas exchange for infants with respiratory difficulties. However, mechanical ventilation may cause lung injury through various mechanisms, including high airway pressure and high tidal volume, leading to acute respiratory distress syndrome, bronchopulmonary dysplasia or multiple organ failure. To prevent these injuries, clinicians, especially neonatologists, treating premature infants with respiratory distress syndrome, should be familiar with ventilator-induced lung injury and its preventive strategies. In this review, the mechanisms of lung injury, the effects of mechanical ventilation on pulmonary microvascular endothelium, extracelluar matrix and alveolar epithelium, and lung protective strategies of conventional ventilation are introduced. Several forms of conventional ventilation for preterm infants are also described.
