연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Chae, Yee Soo,Kim, Jong Gwang,Sohn, Sang Kyun,Cho, Yoon Young,Moon, Joon Ho,Bae, Han-Ik,Park, Jae Yong,Lee, Myung-Hoon,Lee, Hyun-Chul,Chung, Ho Young,Yu, Wansik S. Karger AG 2007 Oncology Vol.71 No.3

<P><I>Objective:</I> Vascular endothelial growth factor (VEGF) is known to be a potent proangiogenic factor. This study evaluates the potential association of three VEGF gene polymorphisms (-460T > C, +405G > C, and 936C > T) with the susceptibility to and clinicopathologic characteristics of gastric cancer. <I>Methods:</I> The VEGF genotypes were determined using paraffin-embedded tissue from 413 patients who underwent a surgical resection and peripheral blood lymphocytes from 413 healthy controls by PCR-RFLP assay. <I>Results:</I> There was no difference in the allele frequency of -460T > C polymorphism. However, for the +405G > C polymorphism, the +405C allele was associated with a significantly decreased susceptibility to gastric cancer [odds ratio (OR) 0.686; 95% confidence interval (CI) 0.564-0.834]. Although there was no significant difference in the distribution of the 936C > T polymorphism between the two groups, the 936T allele was associated with a decreased susceptibility to gastric cancer (OR 0.757; 95% CI 0.591-0.970). In the haplotype analyses, the haplotype TCT (OR 0.405; 95% CI 0.263-0.624) was most closely associated with a decreased susceptibility to gastric cancer. However, no significant association was observed between the frequency of the genotypes or alleles and the clinicopathologic characteristics of gastric cancer. <I>Conclusion:</I> These observations imply that the VEGF gene polymorphisms may be associated with the susceptibility to gastric cancer. However, further studies of other VEGF sequence variants and their biological functions are needed to understand the role of the VEGF polymorphisms in determining the susceptibility to gastric cancer.</P><P>Copyright © 2006 S.

Temporal trends and in-hospital outcomes of primary percutaneous coronary intervention in nonagenarians with ST-segment elevation myocardial infarction

( Joon Young Kim ),( Myung Ho Jeong ),( Yong Woo Choi ),( Yong Keun Ahn ),( Shung Chull Chae ),( Seung Ho Hur ),( Taek Jong Hong ),( Young Jo Kim ),( In Whan Seong ),( In Ho Chae ),( Myeong Chan Cho ) 대한내과학회 2015 The Korean Journal of Internal Medicine Vol.30 No.6

Background/Aims: Data regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in nonagenarians are very limited. The aim of the present study was to evaluate the temporal trends and in-hospital outcomes of primary PCI in nonagenarian STEMI patients. Methods: We retrospectively reviewed data from the Korea Acute Myocardial Infarction Registry (KAMIR) from November 2005 to January 2008, and from the Korea Working Group on Myocardial Infarction (KorMI) from February 2008 to May 2010. Results: During this period, the proportion of nonagenarians among STEMI patients more than doubled (0.59% in KAMIR vs. 1.35% in KorMI), and the rate of use of primary PCI also increased (from 62.5% in KAMIR to 81.0% in KorMI). We identified 84 eligible study patients for which the overall in-hospital mortality rate was 21.4% (25.0% in KAMIR vs. 20.3% in KorMI, p = 0.919). Multivariate analysis identified two independent predictors of in-hospital mortality, namely a final Thrombolysis in Myocardial Infarction (TIMI) flow < 3 (odds ratio [OR], 13.7; 95% confidence interval [CI], 3.2 to 59.0; p < 0.001) and cardiogenic shock during hospitalization (OR, 6.7; 95% CI, 1.5 to 30.3; p = 0.013). Conclusions: The number of nonagenarian STEMI patients who have undergone primary PCI has increased. Although a final TIMI flow < 3 and cardiogenic shock are independent predictors of in-hospital mortality, primary PCI can be performed with a high success rate and an acceptable in-hospital mortality rate.

Cardiovascular beriberi: rare cause of reversible pulmonary hypertension

Joon Hyuk Song,Sang Soo Cheon,Myung Hwan Bae,Jang Hoon Lee,Dong Heon Yang,Hun Sik Park,Yongkeun Cho,Shung Chull Chae 영남대학교 의과대학 2014 Yeungnam University Journal of Medicine Vol.31 No.1

Cardiovascular beriberi is caused by thiamine deficiency and usually presents as high cardiac output failure associated with predominantly right-sided heart failure and rapid recovery after treatment with thiamine. Because of its rarity in developed countries, the diagnosis can often be delayed and missed. We recently experienced a case of cardiovascular beriberi with pulmonary hypertension which successfully treated with thiamine infusion. A 50-year-old man with chronic heavy alcoholics was refered to our department for dyspnea with mental change. Echocardiography showed marked right ventricular (RV) dilatation and flattening of the interventricular septum with a D-shaped deformation of the left ventricle. Moderate tricuspid valve regurgitation was found and estimated RV systolic pressure was 52 mm Hg. Because of his confused mentality and history of chronic alcohol intake, neurological disorder due to thiamine deficiency was suspected and intravenous thiamine was administered and he continuously received a daily dose of 100 mg of thiamine. Follow up echocardiography showed marked reduction of RV dilatation and improvement of a D-shaped deformation of the left ventricle. He finally diagnosed as cardiovascular beriberi on the basis of dramatic response to intravenous thiamine. Thiamine deficiency can cause reversible pulmonary hypertension, and can still be encountered in the clinical setting. Thus high index of suspicion is critically needed for diagnosis.

( Young Joon Hong ),( Myung Ho Jeong ),( Jang Ho Bae ),( Seok Kyu Oh ),( Seung Woon Rha ),( Seung Ho Hur ),( Sung Yun Lee ),( Sang Wook Kim ),( Kwang Soo Cha ),( In Ho Chae ),( Tae Hoon Ahn ),( Kee Si 대한내과학회 2017 The Korean Journal of Internal Medicine Vol.32 No.4

Background/Aims: We evaluated the efficacy and safety and influence on glucose tolerance by different doses of pitavastatins in acute myocardial infarction (AMI) patients. Methods: Consecutive 1,101 AMI patients who were enrolled in Livalo in Acute Myocardial Infarction Study (LAMIS)-II were randomly assigned to receive either 2 mg of pitavastatin or 4 mg of pitavastatin orally per day. Primary efficacy endpoint was composite of cardiac death, nonfatal myocardial infarction, target-lesion revascularization, and hospitalization for unstable angina, heart failure or arrhythmic events at 12-month. Results: There was no significant difference in primary efficacy endpoint between 2 mg and 4 mg groups (9.07% vs. 9.13%, p = 0.976). The degree of the reduction of low density lipoprotein cholesterol (LDL-C) was significantly greater in 4 mg group compared to 2 mg group from baseline to follow-up (.42.05 ± 32.73 mg/dL vs. .34.23 ± 31.66 mg/dL, p = 0.002). Fasting plasma glucose level was reduced significantly in both groups (.20.16 ± 54.49 mg/dL in 4 mg group and .24.45 ± 63.88 mg/dL in 2 mg group, p < 0.001 and p < 0.001, respectively) and there was no significant change of glycated hemoglobin in two groups from baseline to follow-up (.0.13% ± 1.21% in 4 mg group and .0.04% ± 1.10% in 2 mg group, p = 0.256 and p = 0.671, respectively). Conclusions: Although LDL-C was reduced more significantly by using 4 mg of pitavastatin compared to 2 mg of pitavastatin, the event rate was comparable without adverse effects on glucose tolerance in both groups in AMI patients who were enrolled in LAMIS-II.

Campylobacterosis is the most common food borne bacterial disease in many countries. Food animals and animal products are considered to be the reservoir of the Campylobacter species. The aim of this study was to investigate the antimicrobial resistance of Campylobacter spp. from food animals and raw meats in slaughterhouses. A total of 90 Campylobacter jejuni (C. jejuni) and 127 Campylobacter coli (C. coli) were isolated, for which antimicrobial susceptibility was examined using broth dilution method. Resistance to macrolide antimicrobials was higher among C. coli isolates than among C. jejuni. Among both C. jejuni and C. coli isolates, the most frequently observed resistance was to nalidixic acid, ciprofloxacin, and tetracycline. No erythromycin resistance was observed among C. jejuni isolates from cattle, pig and beef. However, 28.3% (n=13) and 25% (n=3) of C. coli isolates from pigs and pork showed resistance to erythromycin, respectively. The predominant profile of multiple resistance among C. jejuni and C. coli isolates was ciprofloxacin/tetracycline/nalidixic acid resistance (46.7%) and ciprofloxacin/nalidixic acid resistance (31.5%), respectively. This finding has important implication for food safety and public health.
