Classic pulmonary blastoma is a variant of carcinosarcoma which is seen almost exclusively in adults. By contrast, most cases of pulmonary blastoma in children have been described as having an exclusive mesenchymal composition, which was proposed as pleuropulmonary blastoma. Recently we experienced a case of pleuropulmonary blastoma, type 1. This 27-month-old male baby was transferred to our hospital due to the left tension pneumothorax. Chest CT revealed a subpleural pulmonary cystic lesion on the left upper lung and an open cystectomy was performed. Histologically the lesion was composed of variable-sized cystic structures lined with a single layer of respiratory-type epithelium. the underlying stroma was composed of sheets of small, round to oval, primitive tumor cells. Some of them had eccentric, eosinophilic cytoplasm, suggestive of rhabdomyoblastic differentiation. These rhabdomyoblastic cells were fuchsinophilic and positive with desmin and vimentin on immunohistochemistry.

BACKGROUND: Hepatitis B vaccination schedule commonly used in Korea is divided largely into 0, 1, 2 month scheduled vaccination group(0, 1, 2 group) and 0, 1, 6 month scheduled vaccination gorup(0, 1, 6 group). The only difference bet.ween two groups is the interval from 2nd dose to 3rd dose. This st,udy had been carried out, to find whether t.he difference of vaccination interval influence the vaccination complet,ion rate or not. METHODS: Study objects are 135 persons over 20 years old who had heptitis B vaccination more than once in injection room of Dongkuk University Kyong-ju Hospital from Jan. 1st in 1996 to Dec. 31th in 1996. Data about vaccination completion were gathered from record book of injection room and telephone interview. RESULTS: Hepatitis B vaccination completion rate is 73.8% in 0, 1, 2 group and 72.5% in 0, 1, 6 group. The reasons for incomplete vaccination are forgetting vaccinat.ion date(36.4% in 0, 1, 2 group and 50% in 0, 1, 6 group), having no time to spare for vaccination(54.5% in 0, 1, 2 group and 43% in 0, 1, 6 group) and knowing positive HBsAb before completion of scheduled vaccination(9.1% in 0, 1, 2 group and 7% in 0, 1, 6 group). CONCLUSIONS: There is no difference in Hepatitis B vaccination complet,ion rate bet.ween 0, 1, 2 group and 0, 1, 6 group.

PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

PURPOSE: Nutritional as well as genetic and hormonal factors play an important role in the bone mineralization during childhood and adolescence. There are several physical and metabolic changes in obese children, and these changes may influence on the mineralization of the skeleton. The studies about bone mineralization of obese children are rare and contradictory. This study was performed to evaluate the influence of childhood obesity on bone mineral density(BMD). METHODS: The BMD of 49 obese and 41 non-obese children were measured at lumbar spines(L2-L4) using dual energy X-ray bone absorptiometry. Then, the results were assessed and compared according to the degree of obesity and pubertal sex maturation. RESULTS: There were no significant differences in BMD between obese children and non-obese children(0.87+/-.19 g/cm2 vs 0.81+/-.13 g/cm2). BMD increased according to the Tanner' pubertal staging, and the most marked increment was observed at overt puberty. No sex difference in BMD was seen in both obese and non-obese children. BMD was highly correlated with age, height, weight and body mass index(BMI), but there was no significant correlation between BMD and osteocalcin. CONCLUSION: BMD of obese children was not significantly different from that of non-obese children, and BMD also was not changed according to the degree of obesity. These findings suggest that BMD is not influenced by obesity in children.

BACKGROUND: Coronary artery diseases (CAD) are increasing in recent years among Korean due to change of socioeconomic status. Even though death rates due to CAD has increased in Korea, few epidemiologic studies have been done about risk factors of CAD. We conducted a case-control study to analyze risk factors for CAD among Korean. METHODS: The case series comprised 166 patients with angiographically confirmed CAD, who were admitted to Division of Cardiology in Asan Medical Center. The controls were 137 persons composed of patients with normal coronary arteriogram or patients with normal myocardial SPECT for chest pain. We surveyed life style habits, measured anthropometric variables, and analyzed biochemical markers among CAD patients and controls. RESULTS: In univariate analysis adjusted for age and body mass index (BMI), age, obesity, abdominal obesity, hypertension, low HDL-cholesterol, low apolipoprotein A1, and high lipoprotein (a) were associated with CAD in men and women. Smoking, diabetes, and hypercholesterolemia were associated with in men only. Exercise and high HDL-cholesterol were inversely associated with CAD both in men and women. In multivariate logistic regression analysis, smoking, abdominal obesity, low apolipoprotein A1, and high lipoprotein (a) were found as independent risk factors of CAD among men. Abdominal obesity, low apolipoprotein A1, and high lipoprotein (a) were found as independent risk factors among women. CONCLUSION: These finding suggest cessation of smoking and weight control for abdominal obesity are important for prevention of CAD among Korean. The detection of low apolipoprotein A1 and high lipoprotein (a) could be useful for prevention of CAD.

PURPOSE: Nasal stuffness is one of most common symptom in children who suffer from rhinitis although there is still debates at to the best measurable device. The aim of the study was to evaluate the sniff nasal inspiratory pressure (SNIP) with respiratory pressure meter and compare this with the clinical status of patients. METHODS: We enrolled 57 rhinitis patients who visited our hospital during June 2005 to July 2006. They were treated with intranasal steroid spray (mometasone furoate) for first 2 weeks. To evaluate the outcome of treatment, we used symptom score (SS) and measured the SNIP with respiratory pressure meter (Micro RPM, Micro Medical, Rochester, UK) and also measured peak nasal inspiratory flow (PNIF) with peak nasal inspiratory flow meter (Youlten peak flow meter, Clement Clarke Int., London, UK) before and after the therapy. Skin prick test was performed to all patient to classify the atopic (AR) and non-atopic rhinitis (NAR). RESULTS: Among 57 identified patients (median age, 7 years 9 months), 40 AR and 17 NAR were studied. Most patient showed clinically improvement with 2 weeks intranasal steroid therapy (0 wk SS=4.9, 2 wk SS=1.7 in AR; 0 wk SS=4.5, 2 wk SS=1.5 in NAR, P< 0.01). The SNIP of AR group was increased after intranasal therapy (0 wk SNIP=58.5 cm H2O, 2 wk SNIP=76.2 cmH2O; P<0.01). There was also significant improvement in terms of SNIP in NAR group (0 wk SNIP=51.7 cmH2O, 2 wk SNIP=62.9 cmH2O, P<0.01). However, we could not find any correlation between SS and SNIP. Although there was the improvement of symptoms scores, there was no significant difference of peak flow between before and after treatment (71.9-->77.6 L/min, P>0.05). And there was no correlation between SNIP and PNIF measurement. CONCLUSION: The respiratory pressure meter is a useful device to evaluate the therapeutic effectiveness and clinical improvement in pediatric rhinitis patients.
