Questionnaires and blood pressure measurements were administered to 279 medical school undergraduates in 1987 to investigate the relationship between psychosocial factors and blood pressure as well as reliability and validity of the Framingham Type A Behavior Scale(FTA). The reliability coefficients of SCL-90-R and FTA measured by Spearman-Brown haves split test were 0.57-0.91, The factors of FTA extracted by principal component analysis were hard-driving competitiveness factor and impatience factor(2-factor solution). The total score of FTA was positively correlated with relative weight and place raised but the correlations were insignificant, and had significantly positive but weak correlations with depression, anxiety hostility, paranoid, and psychoticism subscales of SCL-90-R. In the univariate analysis of blood pressures, relative weight and family history were significant in systolic pressure in males and economic status was significant in blood pressures in both sexes. For diastolic pressure, relative weight and frequency of alcohol intake were significant in males and relative weight was in females. After controlling relative weight, the frequency of alcohol intake for diastolic pressure and economic status for systolic pressure were significant in males. The important variables selected by stepwise regression analysis were relative weight and economic status for systolic pressure of males and relative weight and the frequency of alcohol to the model, changing coefficient of determination 0.206 to 0.217. In females, economic status and relative weight were selected for systolic pressure and for diastolic pressure body mass index alone, but the model of blood pressure for females was considered to be unstable due to small sample size(56). FTA was unrelated to the blood pressures in both sexes.

BACKGROUND: Intracoronary stent with various designs have been developed to treat dissections or acute closure after angioplasty. The efficacy of flexible coil stent as a bail-out device has been reported. However, the restenosis after stenting still remained as a main limitation like other devices. This study reports on the angiographic follow-up after successful intracoronary stenting with flexible coil stent. METHOD: From April 1993 through July 1994, coronary stenting was tried in 21 patients by a single operator for various indications(acute or threatened closure, suboptimal result after balloon angioplasty). The nineteen(95%) out of 20 patients in whom stent was successfully deployed underwent follow-up coronary angiography 7.6+/-3.0 months after coronary stenting. RESULT: Mean age was 54.7+/-11.3(33-73) years and 16 parients were men. Clinical diagnosis of patients were as follows : stable angina 7, unstable angina 6, old myocardial infarction with stable angina 6 and acute myocardial infarction in 1 patient, respectively. Stents were implanted at left anterior descending artery in 9, left circumflex artery in 5 and right coronary artery in 8. Ten out of 21 stents(47.6%) were found to be renarrowed more than 50% at follow-up coronary angiography. There was no significant difference in clinical and angiographic variables between restenosis group and no-restenosis group. Coronary artery bypass graft surgery was performed in 1 patient for the treatment of restenosis after stenting. Repeat PTCA was performed in 3 patients and remaining 5 patients were followed medically. CONCLUSION: Flexible coil(Gianturco-Roubin) coronary stent is a useful adjunct percutaneous intervention to prevent or minimize complicatioms associated with dissections. Despite favorable initial angiographic and clinical results, 47.6% of stents were found to be renarrowed significantly at follow-up coronary angiography. New techniques or more optimal characters of stents would be desired.

BACKGROUND: The purpose of this research was to compare one hospital family practise residents' diagnostic and therapeutic behavior with a Dupont et al described Guidelines on acute infectious diarrhea in adults and HARRISON'S PRINCIPLES OF INTERNAL MEDICINE 15th edition's algorithm for the management of acute diarrheal patients. METHODS: From March 1, 2003 to April 30, 2003, we reviewed 82 acute diarrheal patients (3.19% of the total patients) who had visited one hospital's emergency room which was located in Jeonju district. Doctor's diagnostic and therapeutic approaches were reviewed on the basis of history and physical exam. Then we compared with the standard algorithm referred above. RESULTS: Inpatients were 36.6% (30 patients) among the total of 82 and 63.4% (52 patients) returned home after symptomatic treatment. Among the 52 return home patients, doctors did not entirely conduct stool exam. Among the 30 hospitalized patients, doctors conducted stool exam in 25% among 4 of 16 high fever patients, in 25% among 2 of 8 moderately dehydrated who had diarrhea more than 10 times per day, and in 60% among 6 of 10 patients whose symptom duration was more than 48 hours. Doctors did not use antibiotics in 76.9% (40 patients) of 52 return home patients. Quinolone and Augmentin tablets were administered to each 6 patients of 12 return home patients. Among the 30 inpatients, Augmentin injection were given to 80% (24 patients) and second-generation cephalosporin with aminoglycoside combination injection to 13.3% (4 patients) and quinolone injection to 6.7% (2 patients). CONCLUSION: Compared with standard algorithm, doctors neglected testing stool examination that may be the most important way to diagnose the specific etiology of acute diarrhea. If we actively utilize the stool exam, it may help in providing the correct diagnosis and suitable treatment.

PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.

BACKGROUND: Total occlusion of the infrarenal abdominal aorta is a very rare disease in clinical practice. The clinical outcome may be poor unless management is attempted promptly. Surgical bypass has been recommended as the treatment of choice for these lesions. However, there was relatively high surgical mortality and morbidity associad with aorto-bifemoral bypass graft in patients with other systemic disease, especially coronary artery disease. As a result, the use of, thrombolysis with percutaneous transluminal angioplasty (PTA) has recently been extended to this disease as an alternative method to surgery. PTA is technically simpler with less morbidity and mortality than surgery.We report our experience with thrombolysis and balloon angioplasty of total aortic occlusion in 14 patients between March 1991 and December 1996. METHODS: Fourteen patients, whose mean age was 59+/-13 years (11 male, 3 female), serve as the study's patients. Aortography was introduced via transbrachial artery. The end hole multipurpose catheter with guidewire was introduced into the thrombotic portion of the total occlusion. Urokinase was infused into the thrombus through the catheter if there were no contraindications. in sysremic thrombolysis. Thrombolytic therapy was continued until the thrombi was resolved and flow was restored. Balloon dilatation was followed in residual stenotic lesions. Stents were implanted in case of suboptimal results after ballooning. RESULTS: Clinical findings were resting leg pain in 6 patients, gangrene in 5 patients, and claudication in 3 patients. The causes of aortic occlusion were thromboembolism in 4 patients and thrombosis of an atherosclerotic aorta in 10 patients. Location of obstruction was below the renal artery in all cases. The clinical outcome of interventional therapy was successful in all cases except one patients. Operative treatment was undertaken in 2 cases because they could not received thrombolytic therapy due to contraindication and complication of thrombolytic therapy (gastrointestinal bleeding). Near normal revascularization was achieved in 3 patients by thrombolytic therapy only. PTA was performed at the stenotic after thrombolytic therapy in 4 patients. Stenting were performed at the stenotic sites after balloon dilatation in another 4 patients. There was bleeding complication in one case. CONCLUSIONS: Interventional therapy such as thrombolytic therapy with PTA is an effective and safe treatment modality for abdominal aortic total occlusion in selected cases. These techniques were very useful in some high risk patients who received surgical bypass procedures.

Aneurysms of the coronary arteries are rare. They may be due to atheroselerosis, mucocutaneous lymph node syndrome, mycotic emboli, syphilis or trauma and occasionally they are congenital. The prognosis appears to be poor and death can occur suddenly from rupture of the aneurysm, peripheral coronary embolism or bacterial endocarditis. Recently surgical treatment has been successful. In a 5 year old patient with ventricular septal defect, two aneurysmal sacs located at the cardiac crux and just posterior to it was proved by coronary angiography and MRI, and successfully excised at operation.

PURPOSE: To describe radiologic findings of burn-associated persistent candidemia of the thorax. MATERIALS AND METHODS: This study included 42 patients with major burns in whom blood culture had shown the presence for more than 24 hours of persistent candidemia. The duration of positive culture for candidiasis ranged from two to 67 days(mean, 15 days). Radiographic(n=42) and thin-section CT findings(n=13) were retrospectively analyzed. The onset, pattern, size, distribution and persistence of parenchymal abnormalities as well as the presence or absence of pleural effusions, mediastinal lymphadenopathy and cardiomegaly were assessed. RESULTS: On chest radiographs, positive findings were noticed in 61.9%(26/42) and on thin-section CT, in 76.9%(10/13). The most frequent radiographic finding was pulmonary nodule(s), observed in 14 patients(33.3%). in 13, these were bilateral. Bronchovascular bundle thickening(n=6, 14.3%), consolidation(n=4, 9.5%), cardiomegaly(n=6, 14.3%) and pleural effusion(n=4, 9.5%) were also observed. Those lesions appeared eight to 129 days(mean, 33days) after the burn. Radiographic abnormalities persisted for seven to 115 (mean, 35) days, regardless of the treatment. Thin-section CT showed parenchymal abnormalities in 10/13 patients(76.9%) and subpleural nodules of less than 1cm in diameter and without halo in all patients. Cardiomegaly, pleural effusion and mediastinal adenopathy were observed on CT in 5(38.5%), 4(30.8%) and 2(15.4%) of the 13 patients, respectively. CONCLUSION: In a high proportion of patients with burn-associated candidemia, chest radiograph and thin-section CT findings were positive. The most frequent radiographic parenchymal abnormality was multiple bilateral nodules.
