1.Effects of Smoking Status on Chronic Obstructive Pulmonary Disease Prevalence in Males 40 years and Older: Findings from the Korean National Health and Nutrition Examination Survey.
Korean Journal of Health Promotion 2014;14(4):155-161
BACKGROUND: This is a study of the prevalence of chronic obstructive pulmonary disease (COPD), which shows high mortality worldwide, and the effects of smoking on COPD by using data from the Korea National Health and Nutrition Examination Survey V. METHODS: FEV1/FEV6<0.73 was used as a diagnostic criterion of COPD. Frequency analysis for prevalence, descriptive statistics for general characteristics and ventilation rate according to age-specifications, and complex sample logistic regression analysis for the effect of smoking on COPD prevalence were used. IBM SPSS Statistics 21 Standard, Complex Samples for Medical Science(Windows) was used for data analysis(alpha=0.05). RESULTS: Prevalence of COPD was 11.6+/-0.5% of Koreans in their forties or over, and 17.5+/-0.8% in males, and 6.2+/-0.5% in females. There was significant increase of COPD prevalence with age increment. Before adjusting for age and smoking index(SI), the COPD possibilities of past and current-smokers compared with non-smoking males were (odds ratio [OR] 2.112 [95% confidence interval [CI] 1.551-2.875]) and (OR 1.834 [95% CI 1.319-2.551]) respectively. After adjustments with age and SI, the COPD possibility of current-smoking was 2.099 (1.382-3.188) times higher and for past-smoking was 1.463 (1.012-2.115) times higher than non-smoking. The P-value of each group was significant. The regression coefficients (B) of current-smoking and past-smoking were 0.741 and 0.380 respectively. The prevalence of COPD increased 1.102 (1.090-1.115) times for every 1 year of age increase, and 1.012 (1.007-1.018) times for every 1 SI increase (P<0.001). CONCLUSIONS: After adjusting for age and SI, the prevalence of COPD in smokers was higher than non-smokers. And current-smoking had a higher OR and higher B than past-smoking.

Tailgut cyst is a rare congenital anomaly arising in the retrorectal space. Malignancy arising from the tailgut cyst is very rare. We experienced a case of adenocarcinoma arising from the tailgut cyst. The findings of this rare tumor are bony destruction of the sacrum on plain radiograph, a cystic mass on ultrasound, a low attenuation mass with calcification and enhancement on CT, and a multiseptated cystic mass containing solid component on MRI.

Clear cell hidradenoma is a much less common primary cutaneous tumor originated from sweat gland. Clinically this tumor occurs more frequently in female than in male and in patients of any age although there is a predilection for the middle and older age groups. The lesion is solitary and represents a cutaneous nodular and cystic mass of slow expansible growth. By light microscopy the lesion has been characterized as a solid cataneous tumor composed of clear epithelial cells which are focally arranged in glandular and cystic patterns. We observed a 37-year-old housewife who had suffered from a tumor on her back for 3 years. The tumor was a pedunculated, soft, fixed mass and 3. 5 * 3 * 1. 5 cm in size. Histopathologic finding showed the tumor to be composed of two main types of cells, fusiform and clear cells.

5.Ependymoma Containing Cartilage: A case report.
Korean Journal of Pathology 1990;24(1):77-81
The presence of cartilage in a glial tumor is exceptional. It frequently occurs in ependymoma of midline location in young child nuder 5 years of age. The mechanism of cartilage and bone formation in ependymoma is thought to be either metaplastic transformation from mesenchymal tissue or direct transformation from the neoplastic glial cells. A case of ependymoma containing cartilage and bone is reported. The patient is a 4 year-old girl, having calcified mass in the 4the ventricle and cerebellar vermis. The pathogenesis of cartilage formation in this ependymoma is more likely to support the mataplastic theory.

8.Significance of End-Tidal Carbon Dioxide Monitoring As a Prognostic Factor of ROSC During Cardiopulmonary Resuscitation.
Journal of the Korean Society of Emergency Medicine 1998;9(4):551-559
BACKGROUND: It is difficult to evaluate the effectiveness of ongoing cardiopulmonary resuscitation(CPR). Recent studies suggest that continuous end-tidal carbon dioxide(ETC02) monitoring may be useful non-invasive indicator of CPR. The purpose of this study is to determine whether ETC02 monitoring during CPR could be used as a prognostic indicator of resuscitation and survival. METHOD: A prospective, clinical study was performed from May 1997 to April 1998 at the department of emergency medicine, Ewha Womans University Mokdong hospital. All patients were immediately connected to mainstream capnometer sensor between the tube and the bag after endotracheal intubation using infrared capnometer. RESULT: The study included 70 patients (39 were men) with a mean age of 55+/-16 years. 37 patients with return of spontaneous circulation(ROSC) had higher maximal ETCO2 during CPR than 33 Patients without ROSC (26.9+/-19.4 vs 10.2+/- 9.0mmHg, p=0.0001). The ETCO2 was not significantly different in relation to age, gender, initial rhythm, and survival time after ROSC. But there was significant difference in immediate cause of arrest in ROSC group (P=0.0016). When maximal ETC02 was less than 10mmHg, we observed sensitivity of 83.8%, specificity of 54.5% in predicting ROSC. There were 6 patients with ROSC in spite of maximal ETCO2 was less than 10mmHg. CONCLUSION: Continuous ETCOB monitoring during CPR may be useful, noninvasive, and valuable predictor of successful resuscitation and survival from cardiac arrest. But ETCO2 should lot be used as a single indicator for the withdrawal of CPR.

10.Drug Interactions between Cardiovascular Agents and Psychotropic Drugs.
Korean Journal of Psychosomatic Medicine 2011;19(2):57-65
There are numerous drug interactions related to many psychotropic and cardiovascular medications. Firstly, the principles in predicting drug interactions are discussed. Cytochrome P (CYP) 450 plays a significant role in the metabolism of these drugs that are substrates, inhibitors, or inducers of CYP450 enzymes. The two most significant enzymes are CYP2D6 and CYP3A4. The ability of psychotropic drugs to act as inhibitors for the enzymes may lead to altered efficacy or toxicity of co-administered cardiovascular agents as a substrate for the enzymes. The following is also a review of the known interactions between many commonly prescribed cardiovascular agents and psychotropic drugs. Most beta blockers are metabolized by CYP2D6, which may lead to drug toxicity when they use in combination with potent CYP2D6 inhibitors including bupropion, chlorpromazine, haloperidol, selective serotonin reuptake inhibitors, and quinidine. Concomitant administration of lithium with angiotensin converting enzyme inhibitors, angiotensin receptor blockers, and diuretics may increase serum lithium concentrations and toxicity. Calcium channel blockers and cholesterol lowering agents are subject to interactions with potent inhibitors of CYP3A4, such as amiodarone, diltiazem, fluvoxamine, nefazodone, and verapamil. Prescribing antiarrhythmic drugs in conjunction with medications are known to prolong QT interval and/or inhibitors on a relevant CYP450 enzyme is generally not recommended, or needs watchful monitoring. Digoxin and warfarin also have warrant careful monitoring if co-administered with psychotropic drugs.
