Serologic tests for syphilis including VDRL and TPHA tests were carried out in 5,413 VISA applicants for emigration, from January, 1981 to December, l984 The results are summarized as follows: 1. In 5,413 VISA applicants, the reactive rate of VDRL test was 2,0% totally. The reactive rate of VDRL test of male was 2. 6%, and that of female was 1. 6% 2. The reactive rate of 1983 was 1.4% and that was the lowest in annual incidence, but there was no statistically significant differences in comparing the annual incidences. 3. The reactive rate increased with age, and males above the 5 th decade revealed an especially high reactive rate. 4. The biologic false positive rate of VDRL teet was 16. 5%, in gl VDRL reactive persons, using TPHA as standard. 5. The quantitative test of VDRL showed low titer below 1: 4 in 88. 4%, and high titer above 1: 8 in 11. 6% of the applicants.

Eccrine angiomatous hamartoma is a distinct developmental anomaly showing, histologically, hyperplasia of eccrine sweat apparatus and of vascular elementa in the same lesion, and clinically, the angiomatous lesions with occasional tenderness and profuse local sweating. Recently, we examined an 18-year-old, otherwise healthy girl having, on the anterior aspect of the right leg, an extensive, irregularly marginated and somewhat bluish, tender, firm subcutaneous mass. The mass was studded with several overlying macular, verrucous or nodular angiomatous patches which showed conspicuous hyperhidrosie. Histological examination revealed marked hyperplasia, hypertrophy and cystic dilatations of eccrine sweat apparatus accompanied by proliferation of the capillary hemangiomatous component and ectopic, thick smooth muscle bundles in the deep dermis and subcutaneous tissue.

BACKGROUND AND OBJECTIVES: Aortic stiffness is believed to be an important risk factor of coronary artery atherosclerosis (CAA), as it directly affects coronary perfusion. The following aspects of the invasively measured aortic pulse wave velocity (PWV) were assessed in relation to CAA: The effect of cardiovascular risk factors on PWV, the effect of PWV on the severity of CAA and on the development of the restenosis after drug-eluting stent (DES) implantation. SUBJECTS AND METHODS: 371 subjects who had undergone coronary angiography were enrolled, with all undergoing an invasive aortic PWV measurement also. 112 patients, who had undergone a DES implantation, were prospectively investigated for the effect of PWV in relation to the subsequent risk of major adverse cardiac events (MACE). RESULTS: Among the conventional cardiovascular risk factors, an age >60 (10.79+/-4.92 vs. 8.35+/-4.02, p=0.0006), diabetes (10.97+/-4.66 vs. 9.26+/-4.70 m/sec, p=0.0118) and dyslipidemia (10.38+/-4.97 vs. 9.47+/-4.55m/sec, p=0.0421) were significantly associated with an increased PWV, but sex, smoking and hypertension were not associated with an increased PWV. The PWV was shown to be significantly associated with the severity of CAD. The odds ratio (OR) of 1m/sec increment in the PWV for an increased vessel score was 1.08 (95% confidence interval (CI): 1.03-1.13, p=0.0017). There were no differences in the incidence of MACE and the changes in the angiographic parameters between the high (>10 m/sec) and low PWV groups. CONCLUSION: The invasively measured aortic PWV was affected by age (>60), diabetes and dyslipidemia, and also showed a strong association with the severity of CAD. The aortic PWV was not a significant risk factor for restenosis following a DES implantation.

BACKGROUND: Measurement of the maximum oxygen uptake in patients with chronic obstructive pulmonary disease (COPD) has been used to determine the intensity of exercise and to estimate the patient's response to treatment during pulmonary rehabilitation. However, cardiopulmonary exercise testing is not widely available in Korea. The 6-minute walk test (6MWT) is a simple method of measuring the exercise capacity of a patient. It also provides high reliability data and it reflects the fluctuation in one's exercise capacity relatively well with using the standardized protocol. The prime objective of the present study is to develop a regression equation for estimating the peak oxygen uptake (VO2) for men with moderate to very severe COPD from the results of a 6MWT. METHODS: A total of 33 male patients with moderate to very severe COPD agreed to participate in this study. Pulmonary function testing, cardiopulmonary exercise testing and a 6MWT were performed on their first visits. The index of work (6Mwork, 6-minute walk distance [6MWD]xbody weight) was calculated for each patient. Those variables that were closely related to the peak VO2 were identified through correlation analysis. With including such variables, the equation to predict the peak VO2 was generated by the multiple linear regression method. RESULTS: The peak VO2 averaged 1,015+/-392 ml/min, and the mean 6MWD was 516+/-195 meters. The 6Mwork (r=.597) was better correlated to the peak VO2 than the 6MWD (r=.415). The other variables highly correlated with the peak VO2 were the FEV1 (r=.742), DLco (r=.734) and FVC (r=.679). The derived prediction equation was VO2 (ml/min)=(274.306xFEV1)+(36.242xDLco)+(0.007x6Mwork)-84.867. CONCLUSION: Under the circumstances when measurement of the peak VO2 is not possible, we consider the 6MWT to be a simple alternative to measuring the peak VO2. Of course, it is necessary to perform a trial on much larger scale to validate our prediction equation.

BACKGROUND: The purpose of this study was to evaluate the toxicity and efficacy of high-dose chemotherapy with busulfan, thiotepa and melphalan (BTM) as a myeloablative regimen in allogeneic bone marrow transplantation (allo-BMT) for patients with acute myelogenous leukemia (AML). METHODS: Twenty-seven patients with AML were enrolled; Sixteen patients had standard risk (SR) diseases (first complete remission (CR1) and de novo AML) and eleven patients had high risk (HR) diseases (second, or subsequent remission, secondary AML, relapsed, or refractory AML, CR marrow with persisting extramedullary manifestation (chloroma), or hypoplastic acute leukemia). The conditioning regimen included busulfan 4 mg/kg/day for a total dose of 12 mg/kg; thiotepa 250 mg/m2/day for a total dose of 500 mg/m2; and melphalan 50 mg/m2/day for a total dose of 100 mg/m2. Cyclosporine A and short-course methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. RESULTS: The median time to recovery a granulocyte count of 0.5 x 109/L was 14 days (range 10~25 days) and platelet transfusion independence was 30 days (range 12~49 days). The major regimen-related toxicities were gastrointestinal-related symptoms including oral mucositis, nausea, vomiting, and diarrhea. All patients experienced oral mucositis (> or = grade 1) and the patients with oral mucositis of equal and greater than grade 3 were 44% in SR and 45% in HR. The toxicities associated with lung, skin, heart and brain were minimal. Three (11%) patients had severe or fatal veno-occlusive disease (VOD). There were five treatment-related death (19%) (hepatic VOD with multiorgan failure (n=3), pneumonia and ARDS (n=2)) within the first 100 days after allo-BMT. There was not a significant difference between SR and HR group (p=0.167). The incidence of acute GVHD equal or greater than grade II was less than 10%. The actual survival at 2 year was 70.4%(95% confidence interval (CI), 54.7%~86.1%)(SR; 81.3% (95% CI; 63.4~99.1%) vs HR; 54.6% (95% CI; 28.7~80.4%), p=0.154). After a median follow-up of 630 days, 18 of 27 (67%, 355~1062 days) patients are alive without evidence of disease. Three of the 27 patients relapsed (SR; 0% vs HR; 55.6% (95% CI; 19.6~71.3%), p=0.004). CONCLUSION: The BTM regimen followed by allo-BMT is associated with acceptable toxicity and appears to have significant activity in patients with AML. It should be used with caution in patients with prior hepatopathy or refractory state who have an increased risk of severe VOD. Busulfan, thiotepa, and melphalan is an effective and alternative myeloablative regimen for patients with AML.

BACKGROUND: Although several hospital-based stroke studies were published, there has not been any reliable data representing the clinical characteristics of stroke in Korea. We analyzed the clinical characteristics of patients with ischemic stroke registered in the Korean Stroke Registry (KSR), which is the largest prospective hospital-based nation-wide stroke registry in Korea. METHODS: The KSR provided standardized protocols for collecting data, which includes the data of demographics, subtypes of stroke, risk factors, and neurological outcome at discharge. The brain imaging studies, including CT or MRI, were performed in all cases. RESULTS: KSR registered 10,811 patients of acute ischemic stroke between Nov. 2002 and Jun. 2004. The large-artery atherosclerosis was the most common subtype (37.3%), followed by small vessel occlusion (30.8%). Hypertension (65.4%) was the most common risk factor, followed by smoking (34.5%) and diabetes (28.3%). Although most of the hypertensive and diabetic patients had been diagnosed before the stroke, less than 45.4% and 32.5% of them were under regular control. The steno-occlusive lesion of extracranial carotid artery was only 29.3% and the ratio of intra- to extracranial artery disease was more than 2 in KSR. Only 20.5% of patients were admitted within 3 hours after stroke onset and 2.1% were treated with intravenous thrombolysis. In-hospital case-fatality was 5.2%, which is relatively comparable to those of previous studies. CONCLUSIONS: The KSR provided informative data in understanding the clinical characteristics of ischemic stroke in Korea. Further analysis of KSR will facilitate clinical trials and development of guidelines for the management of stroke patients.
