PURPOSE: To describe soft-tissue radiographic and high-resolution CT findings of radiation-induced lung injury of rabbit over time and to correlate them with pathologic findings. MATERIALS AND METHODS: 15 rabbits were irradiated in the right lung with one fraction of 2000 cGy. After 4, 6, 12, 20, 24 weeks, 3 rabbits in each group were sacrificed and soft-tissue radiographs and high-resolution CT of their lung tissue were obtained. Radiological findings were correlated with pathologic findings. RESULTS: On soft- tissue radiogram, radiation pneumonitis shown as consolidation with air-bronchogram occurred in 3 cases after 6 weeks, and in 1 case after 12 weeks of irradiation. In addition, pneumonic consolidation with adjacent pleural contraction was seen in 2 cases after 12 weeks of irradiation. Fibrotic changes indicated by decreased volume occurred after 20 weeks and combined bronchiectatic change and bronchial wall thickening appeared after 20 weeks(N=1), and 24 weeks(N=3). HRCT findings of radiation pneumonitis were homogeneous, increased attenuation after 4 weeks(N=3), 6 and 12 weeks (each N=I), patchy consolidation after 6 and 12 weeks(each N=2), discrete consolidation after 12, 20 and 24 weeks(each N=I) and solid consolidation after 20 and 24 weeks(each N=2). Pathologically radiation pneumonitis and pulmonary congestion were seen after 4 and 6 weeks. After 6 weeks, collagen and reticulin fibers were detected along alveolar wall. Mixed radiation pneumonitis and fibrosis were detected after 12 weeks. 20 weeks after irradiation, fibrosis was well defined in interstitium and in 24 weeks, decreased number of alveoli and thickening of bronchial wall were defined. CONCLUSION: Radiation pneumonitis was provoked 4 weeks after irradiation on rabbit lung and progressed into radiation fibrosis 20 weeks after irradiation on soft-tissue radiographs and high-resolution CT. High-resolution CT is more precise in detecting early radiation pneumonitis and detailed pathologic findings.

Patients with atypical or incomplete Kawasaki disease are at same risk for development of coronary artery complications as typical Kawasaki disease. In this communication we report six patients with unusual presentation of Kawasaki disease complicated by coronary artery aneurysms, in whom correct diagnosis were not made in time for proper treatment. One of these patients died from massive myocardial ischemia due to giant aneurysms along the entire coronary artery system. These patients had either less than enough number of diagnostic criteria at initial presentation or diagnostic signs which occurred over an extended period of time, resulting in difficulty in diagnosis during the acute phase. As a result, none of these patients received intravenous gamma globulin treatment. Thus strict adherence to currently accepted criteria for diagnosis of Kawasaki disease may lead to failure to recognize atypical form of this illness with potential sequelae of myocardial ischemia or sudden death. We would like to emphasize from this experience that clinicians must be aware of the wide variations in clinical presentation of Kawasaki disease and take an aggressive approach in making correct diagnosis by obtaining early cardiac evaluation in order to initiate prompt treatment with intravenous gamma globulin.

PURPOSE: To verify the association between cigarette smoking and bladder cancer in the Korean population, as smoking is well known as a risk factor on bladder cancer. The risk of bladder cancer was compared among never-smokers, ex-smokers and current-smokers using a multivariate adjusted incidence rate and the mortality rate of bladder cancer of Koreans. MATERIALS AND METHODS: A total of 348,010 participants were enrolled in this prospective study between 1993 (to 1994) and 2002. All participants completed a self administered questionnaire on cancer risk factors, including smoking habit. Follow up for incident bladder cancer was established. We classified all participants into three categories: current-smoker, ex-smoker and never-smoker, on the basis of their smoking habits. We confirmed bladder cancer from the data of the Korea National Cancer Registry and National Health Insurance Corporation up to (December?) 2002. The multivariate adjusted incidence and the mortality due to bladder cancer were used for both genders for a statistical analysis using a Cox proportional hazards model. RESULTS: The incidence rate of bladder cancer per 100,000 persons in male never-smokers, ex-smokers and current-smokers were 27, 41 and 48, respectively, and the multivariate adjusted relative risks (RR) were 1.3 (95% confidence interval (CI), 0.9-2.0) and 1.7 (95% CI, 1.2-2.3) in ex- and current smokers, respectively. The incidence rate of bladder cancer in women was 4.7, 8.4 and 13, respectively. There was no significant association between the risk of bladder cancer and the amount and duration of smoking. CONCLUSIONS: We concluded that current smokers have an increased incidence and mortality rate of bladder cancer in both genders in the Korean population, but there was no significant difference in relation to the amount and duration of smoking.

BACKGROUND: Total intravenous anesthesia(TIVA) with various kinds of sedatives and synthetic analgesics has many advantages such as no air pollution, no hepatic or renal toxicity and good postoperative pain relief compared with inhalation anesthesia. METHODS: TIVA with fentanyl and propofol was applied to the 25 patients in ASA class I and II. The changes of hemodynamics, arterial blood gas, blood sugar level, hepatorenal function and complications were evaluated perioperatively. RESULTS: Systolic blood pressure and mean arterial pressure decreased after induction, but intraoperatively systolic blood pressure became preoperative value while mean arterial pressure increased compared with preoperative value. Heart rate increased after induction and intraoperatively. At recovery room there were no clinically significant changes in the data of arterial blood gas. The blood sugar level slightly increased during postoperative period. There were no clinically significant changes in hepatic or renal function test of postoperative 3rd day compared with preoperative one. The chief complications of TIVA during anesthesia were pain on injection site and slight movement, while nausea or vomiting, dizziness and urinary retention were the major complications at postoperative period. CONCLUSIONS: TIVA with fentanyl and propofol is considered to have good controllability and it can be applied as one of the general anesthesia methods in the case of contraindications to N2O and volatile anesthetics, but further study will be required to quantify the appropriate dosage of propofol or fentanyl to minimize perioperative hemodynamic change and respiratory depression.
