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.

Background: Depression is well known to be associated with nicotine dependence. Recent studies reported higher depressive score is associated with use of e-cigarettes, however, little study showed the association between depression and both cigarette dual use. The purpose of this study is to evaluate the association between depressive mood and conventional and electronic cigarette dual use among male adults. Methods: Data of 7,459 male adults from sixth and seventh Korea National Health and Nutrition Examination Survey (2014, 2016, and 2018) were analyzed. Patient Health Questionnaire-9 (PHQ-9), current smoking status, and electronic cigarette use status were evaluated among them. The association between depressive mood and electronic cigarette use were assessed after adjusting age, education, income, alcohol, and perceived stress level using multivariate logistic regression analysis. The risk of depressive mood for dual users were also assessed. STATA 11.0 (Stata Corp., College Station, TX, USA) were used. Results: The both group of e-cigarette current user or ex-user reported higher depressive scores (PHQ-9) than never-user group (never-user group 1.94±0.05, ex-user group 2.57±0.13, current user group 2.69±0.22, P<0.001). In the multivariate logistic analysis, 1 point increase of depressive mood score was associated with risk of e-cigarette current use (odds ratio [OR], 1.062; 95% confidence interval [CI], 1.021-1.105) among total male adult group or conventional & electronic tobacco dual use (OR, 1.054; 95% CI, 1.012-1.098) among current smokers. Conclusions Depressive scores were positively associated with e-cigarette use or both conventional or e-cigarette use. It is necessary to evaluate and treat smoker’s depressive mood for tobacco control.

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 evaluate the prevalence and the patterns of sterile gas shown at computed tomography(CT) after transarterial embolization(TAE) for primary hepatic tumor. MATERIALS AND METHODS: Among 102 patients who performed TAE for hepatoma, thirty-four in whom follow-up CTwas underwent constituted the basis of our study. At CT, we evaluated the patterns and locations of intratumoral gas. We also reviewed the clinical data to exclude an infectious origin of intratumoral gas. RESULTS: Of 34 patients, intratumoral gas was detected in 11 patients(32%), in all of whom Gelfoam was used as an embolic material. The initial tumor size measured at pre-TAE CT was larger in patients with intratumoral gas than in patients without it(p < 0.005). No specific patterns or locations of intratumoral gas were noted on CT scans. No patients had clinical signs and symptoms that suggested infection. CONCLUSION: Intratumoral gas formation without clinical evidence of infection is not an infrequent finding after TAE for hepatoma, especially when Gelfoam is used and when the tumor is large in size. This finding may be a part of postinfarction syndrome and should not be misinterpreted as an postprocedural abscess formation.

STATEMENT OF PROBLEM: Several domestic dental implants have been developed since dental treatment being implants are increasing and popularized. However, they have not been used in domestic market like imported goods. MATERIAL AND METHODS: This study was carried out to compare domestic and imported implants in aspect of fitness, dental implant fixture and abutment screw using scanning electron microscope. All experiments were performed under dry condition. RESULTS: 1. Only in aspect of relation of dental implant fixture and abutment screw, except only one group with point contact, good fitness was existed. 2. Home products must presevere in their efforts, so as excellent to fit.
