Myocardial bridging is defined as segmental engulfment of a major epicardial coronary artery by myocardial fibers, causing a systolic narrowing or milking effect of the coronary arterial segment. During systole, the intramuscular part of coronary artery is compressed by contraction of overbridging ventricular muscle, therefore blood flow distal to the lesion is impaired and angina pectoris or acute myocardial infarction may occur. We experienced a case of Non-Q myocardial infarction in a 42 years-old female patient with myocardial bridge at the proximal and middle part of left anterior descending coronary artery.

Exercise is one of the most ubiquitous triggers of acute bouts of asthma. Late asthmatic responses(LARs) have been described following strenuous exercise, as in allergen-induced asthma. However, most studies have reported that airway responsiveness is not increased after exercise, even in subjects with LAR to exercise. This suggests that LAR after exercise may not be associated with inflammatory changes in the airways. We have frequently seen asthmatic children whose complaint is that symptoms are exacerbated at night after strenuous daytime exercise. Furthermore, airway responsiveness to allergen was reported to increase after LAR to exercise. Therefore, it is crucial to know whether exercise can induce airway inflammation, as in allergen-induced asthma. As an indirect measure to investigate it, we measured the activation status of eosinophil granulocyte in the peripheral blood during the early and late phase of exercise- or allergen-induced asthma. Eight subjects who showed early asthmatic response(EAR) and LAR(group 1), or EAR only (group 2) to allergen (Dermatophagoides pteronyssinus) challenge were selected. Similarly eight subjects who showed EAR and LAR(group 3), or EAR only (group 4) to exercise were selected. Blood samples were drawn at baseline, the early phase, the late phase, and 24 hours after each stimuli. Eosinofphil cationic protein (ECP) was measured in the serum. Eosinophil granulocytes were separated and the production of leukotriene C4 (LTC4) from purified eosinophfis was measured after stimulation with the calciumionophore. Serum levels of ECP were unchanged at EAR after allergen or exercise challenge. In the dual responder to allergen (group 1), serum ECP level was elevated at LAR and 24 hours after allergen challenge, as compared with the baseline level. On the other hand, in the dual responder to exercise (group 3), it remained unaltered up to 24 hours after exercise challenge. Eosinophils at EAR after allergen or exercise challenge in each group generated the similar amounts of LTC4 as baseline values. In group 1, the production of LTC4 was slightly increased though not significantly at LAR, and significantly increased 24 hours after allergen challenge. In group 3, it was increased significantly at LAR, but restored to the baseline values at 24 hours after exercise challenge. These results indicate that not only allergen but also exercise can activate eosinophils in accordance with LAR. The present findings suggest that LAR to exercise may also have the potential to induce airway eosinophilic inflammation although its duration may be shorter than that of LAR to allergen. Therefore exercise should be understood not only as a triggering factor of bronchoconstriction but also as one that incites or deteriorates airway inflammation.

Crohn's disease is an acute or chronic inflammatory disorder, characteristically non- specific granuloxaatous neerotiziag, cicatrical low grade inflammation, occuring in various portions of the entire oro-gastraintestinal tract. The etiology is not clearly defined and rather uncertain. The disease is a heterogenous & dubious entity with multiple systemic manifestations. The incidence of the disease is geographically unequal in world wide distrihution. And male and female are equally involve. In June, 1985, a case of 17-year-old female patient, who was diagnosed by clinico-micro- scopic examination at Han Yang Univ. hospital. And then, we report with a review of world literatare.

To evaluate the associations between cyberbullying behaviors and problematic internet use, and to compare psychopathologic symptoms in victims, perpetrators, and victims-perpetrators of cyberbullying to those in youths who were not involved in cyberbullying. A total of 4531 youths (11-14 years of age) were recruited from elementary and middle schools. Among 4531 youths, 9.7% were involved in cyberbullying; 3.3% were only victims; 3.4% were only perpetrators; and 3.0% were victims-perpetrators. Cyberbullying behaviors were associated with problematic internet use as well as various psychopathologic symptoms. Depressive symptoms were associated with cyberbullying victimization, and rule-breaking behaviors and aggressive behaviors have relevance to cyberbullying perpetration. Greater attention needs to be paid to identify youths earlier who are involved in cyberbullying and prevent serious adverse consequences in them.

Background: Insufficient physical activity is a major risk factor for cardiovascular disease, and some studies report relationship between physical activityand hearing. We aimed to analyze association between hearing loss and physical activity level in Korean adults. Methods: We used data from the 6th Korea National Health and Nutrition Examination Survey. Insufficient physical activity was defined as a combinedphysical activity of less than 150 minutes per week.. Hearing loss was identified when the audible threshold decreased more than 40 dB. Weperformed multiple logistic regression analysis of major covariates and stratified the participants by age (≥60 versus <60). Results: We analyzed 3,237 participants for whom no values were missing. In the final multivariate logistic analysis, the odds ratio of hearing loss was1.227 (95% confidence interval [CI], 1.008–1.494) in the all frequency group and 1.361 (95% CI, 1.073–1.727) in the low frequency group. The resultfor the high frequency group was not statistically significant. In the group aged ≥60 years, the odds ratio of hearing loss in the all, low, and highfrequency groups were 1.277 (95% CI, 1.011–1.613), 1.405 (95% CI, 1.074–1.839), and 1.298 (95% CI, 1.013–1.662), respectively. Conclusion In this study, insufficient physical activity was associated with hearing loss in Korean adults. This result was more significant in the groupaged ≥60 years. Further studies should aim to validate these results and determine the causal relationship between physical inactivity and hearingloss.

An alveolar soft part sarcoma(ASPS) is a rare malignant soft tissue tumor, which metastasizes to the lung, bone and brain. Recently, we encountered an unusual case of a metastatic ASPS to the bilateral breasts in a 27-year-old woman. She had undergone surgery for an ASPS in her right thigh two years ago, which metastasized to the breast on three occasions, 15 months, 20 months and two years after surgery.

Objective: This study aimed to analyze the correlation of horizontal and sagittal planes used in two-dimensional diagnosis with lip canting by using threedimensional (3D) analysis. Methods: Fifty-two patients (25 men, 27 women; average age: 24 years) undergoing treatment for dentofacial deformity were enrolled. Computed tomography images were acquired, and digital imaging and communication in medicine files were reconstructed into a 3D virtual model wherein horizontal and sagittal craniofacial planes were measured. Subsequently, the correlations of lip canting with these horizontal and sagittal planes were investigated. Results: The mandibular symmetry plane, the occlusal plane, Camper’s plane, the mandibular plane, Broadbent’s plane, and the nasal axis plane were correlated with the amount of lip canting (Pearson’s correlation coefficients: 0.761, 0.648, 0.556, 0.526, 0.438, and 0.406, respectively). Planes associated with the lower part of the face showed the strongest correlations; the strength of the correlations decreased in the midfacial and cranial regions. None of the planes showed statistically significant differences between patients with clinical lip canting (> 3°) and those without prominent lip canting. Conclusions The findings of this study suggest that lip canting is strongly correlated with the mandibular symmetry plane, which includes menton deviation. This finding may have clinical implications with regard to the treatment of patients requiring correction of lip canting. Further studies are necessary for evaluating changes in lip canting after orthognathic surgery.

Dissection of the interventricular septum by aneurysm of sinus of Valsalva is a rare lesion and has poor prognosis. However, it can be diagnosed noninvasively with echocardiography and managed well by surgical repair. A 55 year old female was readmitted due to aggravated exertional dyspnea. She was implanted with permanent pace-maker due to complete atrioventricular (AV) block of recent onset at a community hospital. Previous diastolic murmur near aortic area was changed to a new continuous murmur. The diagnosis of an aneurysm of sinus of Valsalva dissected into the interventricular septum was confirmed by routine two-dimensional echocardiography. The neck of the aneurysm was closed primarily with patch and aortic valve replacement was done. The pro-gnosis was good. The finding of AV block of recent onset and obscure origin in a young patient should alert the physician to the possibility of an aneurysm of sinus of Valsalva and warrants systematic echocardiography.

OBJECTIVE: The purpose of this study was to compare the efficacy and the safety of two different dose regimens of intravaginal misoprostol for labor induction. METHODS: Sixty-seven consenting women with maternal or fetal indication for labor and no prior cesarean delivery were randomly assigned to receive either vaginal misoprostol 100 microgram or 50 microgram every 4 hours with maximum 6 doses. Uterine contraction, abnormal fetal heart rate pattern, mean time from induction to vaginal delivery, apgar score, and meconium staining were compaired. RESULTS: In two groups, dermographic characteristics and the average number of doses of misoprostol used were simliar. The group who were administered 100 ug misprostol showed shorter average time interval from induction to delivery. Both groups showed similiar result in terms of tachysystole, abnormal fetal heart rate tracing, meconium passage, fetal weight, low 1-min and 5-min Apgar scores, and admission to the neonatal intensive care unit. CONCLUSION: The optimal misoprostol dose to induce labor in term pregnant women has not been established. We also could not find any difference between two groups (100 microgram or 50 microgram every 4 hours) in time interval from induction to delivery and neonatal outcomes.
