The purpose of the study was to explore the effect of 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hour on the frequency of "red man syndrome", phlebitis and length of peripheral catheter placement of infected patients, in order to provide safe infusion method for reducing vancomycin-induced RMS and phlebitis. The subjects of the study consisted of 16 hospitalized patients; 3 oncology and gastro-intestinal patients, 1 neurological patient, 6 thoracic surgical patients and 6 orthopedic patients, who had received vancomycin from July to October in 1999 at S-hospital. The dependent variables were the incidence of RMS, phlebitis and the length of peripheral catheter placement. The incidence of RMS was checked by an inspector at the first night whenever the infusion method of vancomycin was changed. RMS was observed every 15 minutes during an hour for symptoms of RMS such as itching, erythema, chest pain and systolic blood pressure. Incidence of phlebitis was assessed by inspector twice a day from the insertion of peripheral catheter to the removal of the catheter. The data were analyzed by percentage, mean, X2-test, t-test, repeated ANOVA, and logistic regression analysis using the SPSSWIN program. The results are summarized as follows; 1. No significant difference was identified in frequency of RMS between the experimental group and control group. 2. There was no significant difference in the change of systolic blood pressure as the time goes on between the experimental group and control group. 3. The incidence of phlebitis was significantly lower in the experimental group than in the control group. 4. The length of peripheral catheter placement was significantly longer in the experimental group than in the control group. 5. Other drugs administrated with vancomycin didn't influence the occurrence of phlebitis. However, the infusion method of vancomycin influenced the occurrence of phlebitis. The results suggest that 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hours may decrease the incidence of phlebitis and increase the length of peripheral catheter placement compared to 1 hour infusion of vancomycin(1g) in 100ml of isotonic saline every 12 hours. However, it does not reduce the incidence of RMS.

BACKGROUND: The characterization of normal coronary blood flow dynamics should provide crucial guidelines for the accurate functional assessment of diseased coronary artery. However, the regional characteristics of coronary blood flow dynamics in normal human coronary artery have not been fully evaluated. METHODS: We performed proximal and distal segment velocity measurement of angiographically normal left anterior descending(LAD) and right coronary artery(RCA) in 25 patients(14 males, 12 females, age 50+/-10 yesre) with atypical chest pain. Spectral flow velocity parameters including average peak velocity(APV), average diastolic peak velocity(ADPV), average systolic peak velocity(ASPV), and diastolic-to-systolic velocity ratio(DSVR) were measured using 0.014 inch 15MHz Doppler wire at baseline and intracoronary adenosine-induced maximal hyperemic state. Coronary flow reserve(CFR) was calculated from the ratio of hyperemia to baseline APV. RESULTS: Comparison between LAD with RCA. LAD showed significantly higher APV than RCA at baseline(proximal ; 18+/-6cm/s vs 14+/-4cm/s, p<.005, and distal ; 17+/-6 cm/s vs 12+/-4cm/s, p<.005. LAD showed significantly higher ADPV and lower ASPV than RCA, therefore significantly higher DSVR than RCA> CFR was significantly lower in LAD than in RCA(proximal ; 301+/-0.9 vs 3.8+/-1.0 , p<3001, and distal ; 3.1+/-0.7 vs 3.6+/-0.8, p<.05). Comparison between proximal with distal segment. There was significant reduction in APV and ASPV from proximal to distal segment in RCA, but not in LAD. There was significant increase in DSVR from proximal to distal segment in RCA, but not in LAD. There was no difference in CFR between proximal and distal segment in both coronary arteries. CONCLUSION: We measured coronary blood flow velocities in angiographically normal coronary artery to characterized normal coronary blood flow dynamics and provide the reference values for the assessment of coronary artery disease. Significant regional differences of coronary blood flow velocities should be considered when we assess the diseased coronary artery.

The effects of oral nicorandil were evaluated in 32 patients with angina pectoris who were diagnosed by typical chest pain and postitive treadmill exercise test from December 1986 throught May 1987. The effects were measured by clinical improvement rating at 4 and 8 weeks after administration of nicorandil, and by repeated treadmill exercise test in 16 patients. The results were as follow's: 1) Clinical improvement was observed in 23(71.5%) and 25(78%) of 32 patients at 4 and 8 weeks after oral nicorandil. 2) Repeated treadmill exercise test of 16 patients showed significant prolongation of exercise duration (464+/-148 seconds vs. 526+/-174, p<0.05). 3) Hemodynamic data like blood pressure or heart rate were independent of nicorandil administration. 4) Three patients complained of headache, and one of them discontinued nicorandil. Mild indigestion was also found in another one patient.

Spontaneous hemorrhage in the patients undergoing hemodialysis is the ralatively common problem, but spontaneous mediastinal hemorrhage in such patients reported only few cases. We experienced a case of spontaneous mediastinal hemorrhage in chronic hemodialysis patient who complained of continuous pleuritic chest pain and mild dyspnea. The diagnosis was made dy chest computed tomography,magnetic resonance imaging and percutaneous fine needle aspiration of liquified dark reddish old blood material guided by ultrasonography. Treatment is usually conservative, with blood volume replacement and intensive hemodialysis using regional heparinization. We report on a patient undergoing hemodialysis due to endstage renal disease who developed spontaneous mediastinal hemorrhage.

Intramural hematoma of the esophagus is a rare cause of chest pain. Varying degrees of submucosal dissection and rupture of the esophagus can induce intramural hematoma of the esophagus. It is viewed as a complication of endoscopic sclerotherapy of esophageal varices, and is likely caused by an elevation in intraesophageal pressure due to factors such as blood coagulation abnormality, drugs, trauma or vomiting. We describe one case of pill-induced spontaneous intramural hematoma that was successfully managed by conservative treatment and discuss the case with a review of the literature.

BACKGROUND: To evaluate the safety and effectiveness of rosiglitazone/metformin in patients with type 2 (non-insulin-dependent) diabetes. METHODS: A total of 982 patients were enrolled by 19 physicians from November 2003 to November 2010. Patients treated with rosiglitazone/metformin at least once, were included in safety assessment. The incidences of adverse events (AEs) and serious adverse events (SAEs) were estimated. The effectiveness of rosiglitazone/metformin was evaluated through change in fasting blood glucose (FBG), 2-hour postprandial glucose (2hr PPG), Hemoglobin A1c (HbA1c). RESULTS: Of the 982 patients, 713 patients with the mean age of 56.4 +/- 11.5 years were included in the safety assessment. A total of 130 AEs were reported from 110 patients (15.4 %). The most frequent AEs were upper respiratory infection (2.4 %), oedema (2.2 %), gastritis (1.3 %), and weight increase (1.1 %). The incidence of unexpected AEs was 5.9 % (42/713, 47 AEs). Three SAEs such as bacterial pneumonia, hyperglycaemia, chest pain were reported in 2 patients. As it is about effectiveness, patients showed statistically significant reductions after treatment of rosiglitazone/metformin in FBG, 2hr PPG, and HbA1c (P<0.001 by paired t-test, for all). CONCLUSION: Our data suggest that rosiglitazone/metformin is well tolerated and effective in Korean patients with type 2 (non-insulin-dependent) diabetes.

BACKGROUND: The interest of patients with chest pain and normal coronary arteries has been increased since 1960. From the year 1973, the syndrome representing these characteristics has been classified as syndrome X. Treadmill test and exercise TI-201 SPECT are important in the diagnosis of syndrome X. This study was designed to evaluate the clinical value of exercise TI-201 SPECT and the difference of clinical characteristics between exercise TI-201 SPECT positive(Group A) and negative (Group B) in patients with chest pain and normal coronary angiogram. METHODS: Twenty seven patients with chest pain and normal coronary angiogram underwent echocardiogram and exercise TI-201 SPECT. Patients received 2 mCi of thallium intravenously during exercise, redistribution images were performed 4 hour later and second dose of 1 mCi of thallium was injected at rest immediately thereafter. These three sets of image(stress, redistribution and reinjection) were analyzed. RESULTS: 1) 12 of 16 patients in Group A, none of 11 patients were positive on exercise treadmill test(p<0.005). 2) The incidence of systemic hypertension in Group A was significant greater than Group B(p<0.05). 3) The left ventricular end diastolic pressure was significantly higher in Group A than in Group B (p<0.05). CONCLUSION: The exercise TI-201 SPECT is a useful method to evaluate the patients with chest pain and normal coronary angiogram and the reversible perfusion defects on the exercise TI-201 SPECT might be related to systemic hypertension and elevated left ventricular end diastolic pressure.

BACKGROUND: Hypertension is a major and growing public health problem and it calls for life-long management. The antihypertensive agents are still playing major roles in the management of hypertension. We studied the effect of the long-term therapy with a new calcium channel blocker, felodipine in patients with essential hypertension. METHODS: We recruited 31 patients with mild to moderate essential hypertention and gave them 5mg (1 tablet) of felodipine(Munobal(R)) once daily for 12 months. We measured the blood pressure and the heart rate every month and tried to detect any untoward symptoms and signs during the whole observation period. Baseline work-up for the hypertensive patients were done as usual before and after the study. RESULTS: The average systolic and diastolic blood pressures were 162.7+/-9.7/99.6+/-7.4mmHg respectively before the administration and they came down to the level of 139.7+/-15.0/87.3+/-8.6mmHg respectively at the end of the 1st month (p<0.05). This trend was maintained during the whole observation period, so they were 141.2+/-11.0/85.6+/-8.2mmHg respectively at the end of the study (p<0.05). Untoward drug reactions such as gastrointestinal troubles, facial edema, leg edema, chest pain and headache were present in 11 patients (35%) but they were not serious. There was no case in which the drug was withdrawn. There was one case in which the level of the serum triglyceride increased after the administration of the drug. CONCLUSION: Felodipine has good and persistent hypotensive effect and it is safe and easy to use.
