Excessive sweating of the face has a strong negative impact on the quality of life for many persons. We have experienced 10 patients with facial hyperhidrosis among the 150 essential hyperhidrosis patients They were 9 male and 1 fatale patients and their age range was 20 to 47 years(mean age 33.8 years). All patients, except one, received bilateral thoracic sympathectomy via VATS. One patient was done via minithoracotomy due to severe pleural adhesion. During the followup period, there was no recurence of facial sweating. Hone of the patients showed Horne 's syndrome.

뇌졸중, 심근경색 등의 심혈관질환은 암과 더불어 우리나라의 주요 사망원인이다. 2002년 통계청이 발표한 2001년 사망원인통계를 보면 인구 10만명 당 암이 123.5명으로 1위, 뇌졸중 등 뇌혈관 질환이 73.8명으로 2위, 심장질환(허혈성 심장질환과 기타 심장질환 포함)이 34.2명으로 3위였다. 이러한 심혈관질환의 예방을 위해서는 평소 뇌혈관질환을 일으킬 수 있는 위험인자들을 잘 관리할 필요가 있다. 사망률이 높은 심혈관질환의 주요 위험요인은 성별, 연령 등 선천적으로 타고나는 고정요인과 흡연, 비만 등 본인의 노력에 따라 생활습관을 바꿔 위험을 낮출 수 있는 변동요인으로 나눌 수 있다. 성별, 연령은 바꿀수 없지만 생활습관은 바꿀 수 있다. 심혈관 질환 예방에 있어서 가장 중요한 것은 기본적인 건강관리 수칙인 금연, 과음하지 않기, 균형있는 올바른 식생활, 규칙적인 운동, 표준체중 유지하기, 정기검진 등이다.특히 심혈관 질환은 채소류와 식물성 단백질, 식물성 지방 등을 위주로 한 식이요법이 도움을 줄 수 있고 튼튼한 혈관을 가지기 위해서 질 좋은 단백질과 비타민ㆍ무기질을 충분히 섭취해야 하며 콜레스테롤의 배설을 돕기 위해 섬유소가 충분한 식사를 한다. 갑자기 추워진 날씨로 생명을 다투는 뇌졸중이나 협심증, 심근경색 등 심혈관 관련 질병이 발생하기 쉬운 겨울철이다. 행사가 많은 연말에 과음을 삼가며 금연하고, 평소 담백한 한식 위주의 식사, 꾸준한 운동 등으로 건강관리에 힘써서 치명적인 심혈관 질환에 미리미리 대비하도록 한다.

From September 1989 to March 1996, 13 patients with prosthetic valve thrombosis underwent reoperdtion on 16 occasions. The mean interval between implantation and reoperation was 27.8 months. The anticoagulation status was inadequate in 44% of th Instances. The majority(75%) were in NYHA functional class IV, 6 of them being in shock. Reoperation was performed for valve replacement(15 of 16 occasions) or thrombectomy(1 of 16 occasions) within 3 to 192 hours(mean 33.5 hours). Operative mortality at reoperation was 25%(4 patients). Re-thrombosis occurred In 3 patients. Long-term outcome was satisfactory in all survivors with a mean follow-up of 30.B months. The present results indicate that an early diagnosis and prompt surgical intervention is needed to decrease operative mortality.

The carotid intima-media thickness (IMT) is an early structural marker of the atherosclerotic process and is the only non-invasive test that is currently recommended by the American Heart Association for evaluation of the risk. However, use of this parameter has a limitation because it assumes uniform thickness throughout the blood vessel, whereas atherosclerosis is a focal phenomenon that is confined to intima. In fact, plaque can be found along the atherosclerotic blood vessels even though its value is unknown. The aim of this study is to analyze the carotid plaque and IMT in the stroke patients. We investigated the patients with ischemic stroke, who were admitted to the department of neurology at the Stroke Special Hospital from January to March 2008. After the carotid IMT and plaque were assessed by B-mode ultrasonography, IMT and carotid plaque to risk variables (age, sex) were analyzed. The distribution of CCA IMT was significantly different in terms of age (p = 0.004). Likewise, the distribution of carotid plaque was also significantly different in terms of age (p = 0.006). Carotid plaque was 69 and 92% in normal and abnormal CCA IMTs respectively. The results showed that the CCA IMT was closely associated with carotid plaque.

We surveyed 586 patients who had been examined CCTA. Out of those patients, 299 (52%) has stenosis of coronary arteries; 166 males (28%) and 133 females (23%). Among them 246 stenosis patients (82.6%) are in 50's to 70's. The number of patients with 50% or more stenosis in more than 1 coronary artery is 299 including 43 males (33.9%) in their 60's and 39 females (37.5%) in their 70's. When a vessel score is higher than 2 points, 70 patients (50.1%) among 139 have 70% or more stenosis; 32 males (39.5%) in their 60's and 27 females (46.6%) in their 70's. It is noted that 14 patients in their 70's show more cases compared to other ages up to 2 or even 5 times when a vessel score is 3 points. LAD shows 77.6% of stenosis, LCX 47.5% and RCA 60.5%. Frequency of a triple vessel disease is high for patients in their 70's; 15 males (36.6%) and 13 females (56.5%) for both. 196 people (33.4%) in the group with stenosis have calcification, while only 40 (6.8%) in the group without stenosis have it. It means that calcification has a significant, if not absolute, correlation with stenosis of coronary arteries.

From February 1980 to September 1995, 31 children between 2 months and 15 years of age with mitral valve disease have undergone mitral valve replacement(MVR) at Yonsei Cardiovascular Center and com- plete follow-up has been obtained on 28 patients. There were 10 males and 18 females whose weight ranged from 4.9kg to 56kg. Two patients died early postopeiatively and the overall hospital mortality rate was 7.1%. These two were infants but there were no statistically significant difference in overall mortality among the age groups(p=0.13). The valve related complication rate was 57.1% in children younger than 5 years of age, which showed higher complication rate compared to older patients(p< 0.05). The bioprosthetic valve have been applied in 7 patients, and its 5-year valve failure-free survival rate was 50% . No mechanical valve failu e had occurred in 21 patients. In considering high re-replacement rate of bioprosthetic valve, mechanical valve is recommended despite its possibility of bleeding and thromboembolic complications. However, the consequences of increasing body size and long-term interposition of a rigid prosthesis in a growing heart will require second valve replacement. En conclusion, mitral valve replacement can be performed tilth satisfactory long-term survival in children, although younger mean age of the children has an important influence on early mortality and com- plication rate. And therefore mitral valve replacement in children younger than 5 years of age needs special consideration.

Background: About 30% to 40% of the patients with pathologic stage I non-small cell lung cancer (NSCLC) die within 5 years after complete resection. The identification of poor prognostic factors and the application of additional treatment are very important to improve the survival rate in resected stage I NSCLC. Materials and methods: Sixty-eight(68) patients who had been diagnosed postoperatively between Janury 1989 and December 1995 as having stage I non-small cell lung cancer according to the TNM classification were studied. The postoperative 5-year survival rate was calculated with the Kaplan-Meier method, and clinico- histopathologic factors including age, sex, operative method, type of tumor cell, T factor, grade of the differentiation in a squamous cell carcinoma, invasion of blood vessel and expression of the nm23-H1 protein were investigated and analyzed. Results: The median survival of the entire group of patients was 58$\pm$3 months, with a 5-year survival of 58.9%. In univariate analysis, invasion of blood vessel and poor differentiation of the tumor cell in a squamous cell carcinoma significantly worsened the survival. In multivariate analysis, invasion of blood vessel and grade of the differentiation of the tumor cells in a squamous cell carcinoma remained independent prognostic factors. High expression of the nm23-H1 protein was related to a high postoperative 5-year survival in comparision with low expression of the nm23-H1 pretein (73.0% vs 50.7%), but there was no statistical significance. Conclusions: These results highlight the negative prognostic value of poor differentiation of tumor cells in a squamous cell carcinoma and invasion of blood vessel in stage I non-small cell lung cancer. Also, further studies are necessary to be determined prognostic value of the T factor and expression of the nm23 protein in non-small cell lung cancer.

Purpose To evaluate the circuit patency after nitinol bare-metal stent (BMS) placement according to the type of access and location of the stent in dysfunctional hemodialysis access. Materials and Methods Between January 2017 and December 2019, 159 patients (mean age, 64.1 ± 13.2 years) underwent nitinol BMS placement for dysfunctional access. The location of stents was as follows: 18 brachiocephalic vein, 51 cephalic arch, 40 upper arm vein, 10 juxta-anastomotic vein, 7 arteriovenous (AV) anastomosis, and 33 graft-vein (GV) anastomosis. Circuit patency was evaluated by the Kaplan-Meier method, and cox regression model. Results A total of 159 stents were successfully deployed in 103 AV fistula (AVF) and 56 AV graft (AVG). AVG showed lower primary and secondary patency at 12-months compared with AVF (primary patency; 25.0% vs. 44.7%; p = 0.005, secondary patency; 76.8% vs. 92.2%; p = 0.014). Cox regression model demonstrated poorer primary patency at 12 months after stenting in the cephalic arch and GV anastomosis compared with the other sites. Conclusion AVF showed better primary and secondary circuit patency at 12 months following the placement of BMS compared with AVG. Stents in the cephalic arch and GV anastomosis were associated with poorer primary patency at 12 months compared to those in other locations.

Between April, 1984 and September, 1988, 459 patients underwent cardiovascular surgery at the Yeungnam University Hospital. Of these, 355 cases were open heart surgeries and 104 cases were non-open heart surgeries. There were 237 patients of acyanotic congenital cardiac anomalies, 40 patients of cyanotic congenital cardiac anomalies, and 85 patients of acquired heart diseases. The sex ratio of cardiovascular diseases was represented as 1:1.3 in male and female. The age distribution was ranged from 1 day to 65 years old. The common congenital cardiovascular anomalies were ventricular septal defect(38.7%), patent ductus arteriosus(25.5%), atrial septal defect(20.7%), Tetralogy of Fallot(8.3%), and pulmonary stenosis(2.4%) in order of frequency. Among 87 acquired cardiovascular diseases, 81 patients underwent operation for cardiac valvular lesions. 51 patients had mitral valve replacement and 13 patients had aortic valve replacement and 17 patients had double valve replacement. The overall mortality of cardiovascular surgery was 3.3% and mortality of open heart surgery was 3.9%.

당뇨병환자의 자가혈당조절에 있어서의 기준이 되는 혈당측정에 있어서 하나의 지침을 제공하기 위해 본 연구는 말초혈관과 상완정맥에서의 혈액을 채취하여 이들 검사물들의 혈당치를 직접적으로 비교했다. 30명의 건강한 한국인 성인 남자(연령 : 평균=30세)로부터, 공복시의 혈액을 세가지의 서로 다른 방법들(우선 손가락 끝에 말초혈관을 울혈이 되도록 한 뒤에, 이후 같은 편의 팔의 상완정맥에서, 마지막으로 다시 처음 검채를 시행했던 바로 그 말초의 천자부위에서 혈액을 짜내는 방법으로.)로 각각의 대상에서 검채하였다. 검사물들의 혈당치는 간편측정용 혈당측정기(Glucocard, KDK Corp., Japan. 1995)로 측정한 결과 상완정맥에서 채취한 혈액의 혈당치(107.58$\pm$21.03mg/dl)가 말초에서 채취한 혈액(울혈 후 : 100.21$\pm$24.03mg/dl, .짜낸 경우 : 97.84$\pm$22.45mg/dl)들 보다 높았다(T=2.86. p=.0081 : T=3.084. p=.0055). 그러나 이 결과는 기타의 연구들에서의 결과와는 일치하지 않았다. 이러한 불일치는 자가혈당측정기가 인슐린 의존형 당뇨환자는 물론이고 비의존성 당뇨환자들의 자가관리에 결정적인 지침이 된다는 점을 고려할 때, 좀 더 통제된 상황에서 더욱 많은 사람을 대상으로 한 임상시험을 통해 자가 혈당측정치에 있어서 기계요인에 대한분석이 이루워질 필요를 시사하고 있다. 또한 동일한 부위에서 서로 다른 방법들(혈관을 울혈을 시킨 천자하여 얻은 경우와 천자 후 그 부위를 짜서 검사물을 얻는 방법)에 의해서 얻어진 혈액의 헐당치 측정 결과 간에 차이가 없는 것으로 나타나서(t=0.72, p=.4791), 일반적으로 혈당치의 측정 시 검채한 양이 부족할 때, 새로이 천자하여 검사를 시행하는 것을 원칙으로 인식하고 있으나 본 연구결과를 볼 때, 이러한 채혈의 방식에 의한 차이는 환자의 안녕의 차원에서 고려하여 필요하다면 간과될 수도 있음을 의미하고 있다.
