Kawasaki disease is an acute febrile illness frequently developed in infants and children. This disease may involve coronary arteries in 15- 25% of the patients and may progress to coronary aneurysms, ischemic cardiac diseases, and sudden cardiac death. Recently we experienced successful balloon angioplasty followed by coronary stenting in a 15-year old boy with unstable angina and severe coronary arterial occlusive disease secondary to Kawasaki disease. He was diagnosed as unstable angina by 24 hours Holter monitoring, treadmill exercise stress test, echocardiography, and Dipyridamole 99mTc-sestamibi scan. And coronary angiogram revealed severe multiple stenosis and aneurysmal changes due to Kawasaki disease. We successfully performed a percutaneous transluminal coronary angioplasty with stent implantation at left circumflex arterial occlusive lesion.

Osteoma is a slow-growing benign tumor composed of mature bone. Osteoma of the nose and paranasal sinuses is usually asymptomatic and most commonly occurs in the frontal sinus, followed by the ethmoidal and maxillary sinus. The occurrence in the sphenoidal sinus and nasal cavity is very rare. We present a case report of a patient with an isolated osteoma in the right nasal cavity presenting with nasal obstruction.

OBJECTIVES: The purpose of this study was to examine the prevalence of allergic rhinitis between urban areas in the adjacent areas to a steel industrial complex and rural areas and the impact of pollutants in the industrialized city on allergic rhinitis. METHODS: From July 28 to August 9 of 2008, 1,043 residents of urban and rural areas in a local community had enrolled in health screening and questionnaire survey. One thousand thirty-three patients also underwent a skin prick test. Prevalence rates of allergic rhinitis were calculated according to residential areas, and the used statistical analysis were Fisher's exact test and chi-square test. RESULTS: In a survey, the fraction of adults, who complained of sneezing, nasal obstruction and rhinorrhea, during a recent 1 year period, showed the significant difference between urban (30.5%) and rural areas (22.4%). The fractions of positive skin prick tests were not different between two areas in each age group. The prevalence of allergic rhinitis was 8.4% in urban areas and 6.9% in rural areas. Considering the age groups, the adults group only showed the significantly higher prevalence of allergic rhinitis in urban areas (8.2% vs. 3.7%). CONCLUSIONS: Unlike the children and adolescents groups, the prevalence of allergic rhinitis in adults group was higher in the industrialized urban areas.

Rheumatoid arthritis (RA) is a multifactorial autoimmune disease whose etiopathogenesis is not well understood. Although soluble (s) forms of 4-1BB (s4-1BB) and 4-1BB legand (s4-1BBL) have been detected in the sera of RA patients, their significance is not known. We compared the serum levels of s4-1BB and s4-1BBL in RA patients with those in systemic lupus erythematosus (SLE) and Behcet's disease (BD) patients. Serum levels of s4-1BB and s4-1BBL were significantly higher in RA patients compared with healthy controls, SLE or BD patients, and the abundance was correlated with disease severity in patients with RA. The serum levels of s4-1BB in RA patients were inversely corroborated with 4-1BB expression levels on activated T lymphocytes. In addition, there was a correlation between serum levels of s4-1BB and s4-1BBL. The augmented secretion of s4-1BB and s4-1BBL levels into the serum may reflect the clinical symptoms of RA and levels of s4-1BB and s4-1BBL in sera at the time of diagnosis may be indicative of the severity and outcome of RA.

Bisphosphonates (BPs) are a class of agent used to treat patient with osteoporosis or malignant bone metastases. BPs can be categorized into 2 groups: nitrogen-containing and non-nitrogen containing. Nitrogen-containing BPs are considered to have more toxicity. Despite their clinical benefits, bisphosphonate-related osteonecrosis of jaw(BRONJ) is a significant complication to patients receveing these drugs. Since the first description of BRONJ in 2003 by Marx, the number of reports on BRONJ has been rapidly increasing. BRONJ is considered as an emerging problem in oral & maxillofacial surgery. Generally, osteonecrosis in the maxilla is rare, however BRONJ is found both in the maxilla and the mandible. This is an important feature of BRONJ compared to common infectious osteomyelitis of the jaw. Growing number of case reports, suggest that bisphosphonate therapy may cause exposed, necrotic bone. BRONJ has simillar features compared to IORN (infected osteoradionecrosis). BRONJ has meaningful features established through the interestigation on histopathologic and radiographic findings. These features have an impact on treatment plan and prognosis. This presentation contemplates on features of histopathologic and radiographic findings in bisphosphonate-related osteonecrosis of the jaw.

BACKGROUND AND OBJECTIVES: We sought to determine whether an elevated homocysteine (Hcy) level is associated with a worse prognosis in Korean patients with coronary artery disease (CAD). SUBJECTS AND METHODS: A total of 5839 patients (60.4% male, mean age 61.3±11.2 years) with CAD were enrolled from 2000 to 2010 at Gangnam Severance Hospital. CAD was diagnosed by invasive coronary angiography. Laboratory values including Hcy level were obtained on the day of coronary angiography and analyses were performed shortly after sampling. Patients were divided into two groups according to their Hcy levels. Baseline risk factors, coronary angiographic findings, length of follow-up, and composite endpoints including cardiac death (CD) and non-fatal myocardial infarction (NFMI) were recorded. 1:1 propensity score matched analysis was also performed. RESULTS: Over a mean follow-up period of 4.4±2.5 years, there were 132 composite endpoints (75 CD and 57 NFMI) with an event rate of 2.3%. Mean Hcy level was 9.9±4.3 µmol/L (normal Hcy 7.9±1.5 µmol/L and elevated Hcy 13.9±5.1 µmol/L). Kaplan-Meier survival analysis showed an association of elevated Hcy level with worse prognosis (p<0.0001). In addition, a multivariate Cox regression analysis showed an association of elevated Hcy level with worse prognosis for both the entire cohort (hazard ratio [HR] 2.077, 95% confidence interval [CI] 1.467-2.941, p<0.0001) and the propensity score matched cohort (HR 1.982, 95% CI 1.305-3.009, p=0.001). CONCLUSION: Elevated Hcy level is associated with worse outcomes in Korean patients with CAD.

With the object of providing a temporary artificial periodonal ligament-like membrane around the dental implant, 10 Branemark type implants were coated with commercially available chitosan(Fluka Co., Buchs, Switzerland) which has a molecular weight of 70,000 and 80% deacetylation degree. Once this bioactive hydrophillic polymer(chitosan) contacts with blood or wound fluids, it becomes swollen and penetrates into the adjacent cancellous bone. Thus the interface between implant and surrounding bone is completely filled with chitosan. This tight junction in early healing phase enhances primary stability. The chitosan coated dental implants were implanted into the fresh patella bones from porcine knees, since the thickness of cortical bone is relatively even and their cancellous structure is homogenous. To test the shock absorbing effect, 1mm delta-rogette strain gage was installed behind the implant. The results showed 1. the principal strain peak value directed to the impact of coated implant was 0.064 0.018(p<0.05) and that of uncoated implant was 0.095(0.032 p<0.05). 2. the peak time delay of coated implant was 0.056sec(0.011 p<0.05) and that of uncoated implant was 0.024sec(0.009 p<0.05). It can be reasoned from this results that the chitosan coating has a shock absorbing effect comparable with a temporary artificial periodontal ligament.

BACKGROUND: There were debates on the relationship between peak expiratory flow (PEF) and oil spill cleanup activity. The aim of this study was to compare the distinction of PEF among pre-works and post-works in Hebei Spirit oil. METHODS: The study subjects were participators of cleanup works. The questionaire on symptoms was done. And PEF was measured. The subjects were sampled on random basis. We then used a logistic regression analysis to evaluate the effects of cleanup works on PEF. RESULTS: Only 66 (35.3%) participants versus 121 showed with low values in PEF before cleanup works. But, 78 (80.1%) participants versus 20 significantly showed with low values in PEF after cleanup works (P = 0.002). On our analysis, measuring their own PEF after cleanup works (Odds ratio [OR], 2.328; 95% confidence interval [CI], 1.218 to 6.624), female gender (OR, 5.841; 95% CI, 3.571 to 9.557), the number of working days on cleanup activities (OR, 2.760; 95% CI, 1.364 to 7.900), and residents (OR, 4.610; 95% CI, 2.488 to 8.544) were shown to be significant risk factors for low value of peak expiratory flow. CONCLUSION: Our results suggest that exposure to petroleum in cleanup works are associated with a significant low value in PEF. But, the heterogeneity of pre-works and post-works groups is a limitation of the study.

BACKGROUND AND OBJECTIVES: We investigated in patients with coronary vasospastic angina whether the exercise ECG test results are influenced by the different modes of exercise load and compared the clinical characteristics including coronary risk factors between patients with positive and negative exercise tests. MATERIALS AND METHODS: This study comprised 34 patients with documented coronary artery spasm without significant stenosis (coronary artery luminal diameter narrowing <70%) and treadmill exercise test. Treadmill exercise ECG test was performed based on Bruce's protocol (graded exercise test, GET) and sudden rapid exercise protocol (non-graded exercise test, NGET) in the morning of the same day. RESULTS: 1) Of 29 patients who underwent both GET and NGET, 19 patients manifested positive result by NGET, whereas only 11 patients did by GET (66 vs. 38%, P=0.04). All patients with positive GET had positive NGET and 8 of 18 patients with negative GET had positive NGET. 2) Of 34 patients who underwent GET, there was no significant difference in frequency of hypertension, diabetes, current smoking, presence of effort chest pain by history, mixed disease (fixed stenosis >50%, <70% of luminal diameter) or total cholesterol level between patients with positive and negative results. In 18 typical variant angina patients by clinical history, 8 of 10 patients with high disease activity (5 times or more attack per week) manifested positive result by GET or NGET, whereas 4 of 8 patients with low disease activity (80 vs. 50%, P=NS). CONCLUSION: In patients with coronary vasospastic angina, sudden rapid exercise could induce more frequently coronary artery spasm than multistage exercise. The result of an exercise test may not be correlated with coronary risk factors, coronary anatomy, effort chest pain, and the disease activity.
