Along with a development of medical technology, a variety of tests, such as laboratory tests, x-ray and endoscopies are being used in health screening tests. As the tests determine the quality of health screening, test items and methods should be carefully selected. This study was to get hold of the test items of major health screening programs in Korea Most of the health screening programmes focused upon detection of risk factors and diagnosis of life - style related diseases (diabetes, hypertension, cardiovascular diseases, hypercholesterolemia, overweight, drinking, smoking, cerebrovascular diseases, osteoporosis) ,cancers (stomach, cervix, lung, breast, liver, colon, prostate, ovary, pancreas, thyroid, esophagus) , infectious diseases (hepatitis, tuberculosis, sexually-transmitted diseases, parasites) , chronic obstructive respiratory diseases, chronic renal diseases (bacteriuria hematuria, proteinuria) , anemia, glaucoma, hearing loss, Alzheimer disease, stress, early psychiatric diseases. The health screening tests were basic physical examination, basic laboratory tests (CBC, urinalysis, liver function tests, lipid tests, glucose, HbAlc, uric acid, electrolytes, serological tests (HBsAg, HBs-Ab, HCV-Ab, HIV-Ab, VDRL) EKG, x-ray (chest PA, CT) , endoscopy (gastroscopy, colonoscopy) , sonography(abdomen, thyroid, pelvis, breast) ,cytology (cervix) , bone density, tumor markets (NMP22, alpha-FP, CEA, CA-19-9, CA12S, PSA) and eye tests. Advanced technologies, like CT, PET, MRI, MRT/Angio, molecular testings) were widely used in hospital health screening programmes .In summary, a variety of tests were utilized in health screening in Korea. Those tests were utilized by stages or according to sex and age in most of health screening programmes, however a few program used tests to excess disregarding health screening subjects.

From 1983, until June, 1990, 10 patients with various type of truncus arteriosus underwent total surgical correction including Rastelli procedure at Seoul National University Hospital. The age at operation ranged from 1 month to 9 years [mean 2.1 years]. Six patients had truncus type I, 3 patients had truncus type II, and one patients had truncus type IIIc. Right ventricular pulmonary artery continuity was established with a porcine valved conduit in 6 patients, mechanical valved conduit in 1 patient, and bovine pericardial conduit in 3 patients. The postoperative right ventricular /left ventricular pressure ratio ranged from 0.4 to 0.71 [mean 0.51${\pm}$0.14]. The lung histology revealed grade II pulmonary obstructive disease even at 4 month of age. Five patients were dead in hospital [50%], and they were less than 2 year of age. One patient, who had severs congestive heart failure preoperatively, died of low output syndrome and the other died of low output syndrome with postoperative bleeding. There were three death, because of a pulmonary hypertensive crisis that might have been prevented. Two of the five survivors had conduit failure over a mean follow up of 42 months [range 1 to 78 months]. Obstructed conduit was removed and a new conduit constructed using the conduit bed as the posterior wall and the patch of bovine pericardium and Dacron as patch the roof of the conduit. One patient died of acute cardiac failure during the operation. Although results in infants less than 2 years old have not been good, current improvement of intra-and postoperative care suggested that prompt repair is indicated for infants with truncus arteriosus.

Objective : The aim of this study was to investigate risk factor, precaution and treatment of aspirated foreign body during dental procedure. Material and Methods : Twenty cases of accidental aspiration of the foreign body, which removed by bronchoscopy at the Asan Medical Center between 2008 and 2012, were analyzed retrospectively. Results : Ten cases of accidental aspiration were occurred during dental procedure. Symtoms include cough(65%), dyspnea(50%), sputum(25%) and wheezing(25%). The most common location of foreign body was right bronchial tree(50%), left bronchial tree(45%) and carina(5%). Patients risk factors were chronic obstructive pulmonary disease, lung cancer, pulmonary tuberculosis, esophageal cancer and vegetative state. Conclusion : Accidental aspiration or swallowing of dental instrument or material is not uncommon accidents in dental practice. Most foreign bodies enter into gastrointestinal tract spontaneously. But aspiration into broncho-trachea can be more serious events and must be treated as an emergency situation. Prompt emergency treatment and removal of the foreign body is necessary to avoid complication. Dentists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental procedures.

The object of this study was to evaluate the single dose toxicity of Yukmijihwangtanggamibang (YMJHTGMB), a polyherbal formula have been traditionally used as prevention or treatment agent for various lung diseases including chronic obstructive pulmonary disease (COPD), in male and female mice. Aqueous extracts of YMJHTGMB (Yield = 16.33%) wasadministered to female and male ICR mice as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy; organ weight and histopathology of 12 principle organs were examined. As results, we could not find any mortality, clinical signs, and changesin the body and organ weight except for soft feces restricted to YMJHTGMB 2,000 mg/kg treated two male mice (2/5; 40%) at 1 day after administration. In addition, no YMJHTGMB-treatment related abnormal gross findings and changes in histopathology of principle organs were detected except for some sporadic accidental findings. The results obtained in this study suggest that the 50% lethal dose and approximate lethal dose of YMJHTGMB aqueous extracts in both female and male mice were considered as over 2,000 mg/kg, the limited highest dosage recommended by KFDA Guidelines.

Particulate matter (PM) is suspended dust that has a diameter of <10 ㎛ and can be inhaled by humans and deposited in the lungs, particularly the alveoli. Recent studies have shown that PM has an adverse effect on respiratory diseases. The aim of this article is to review respiratory diseases associated with PM. According to existing studies, PM is associated with chronic obstructive pulmonary disease, bronchial asthma, and several other respiratory diseases and increases the mortality rates of these diseases. Moreover, increased exposure in the high concentration of atmospheric PM is associated with the development of lung cancer. The most simple and common way to protect an individual from airborne PM is to wear a face mask that filters out PM. In areas of high concentration PM, it is recommended to wear a face mask to minimize the exposure to PM. However, the use of N95 or KF94 masks can interfere with respiration in patients with chronic respiratory diseases who exhibit low pulmonary function, leading to an increased risk of respiratory failure. Conclusionally, reduction of the total amount of PM is considered to be important factor and strengthening the national warning notification system to vulnerable patients and proper early management of exacerbated patients will be needed in the future.

We have observed 501 cases of spontaneous pneumothorax from January 1981 to June 1989 at the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital. Of these, 57 patients have undergone thoracotomy to treat the pneumothorax after closed thoracostomy. These 57 patients were based on this retrospective clinical analysis, and the results were as follows: The ratio of male to female was 4.2:1 in male predominance and the old aged patients, over 50 years old, occupied 47.3% of all patients. Primary spontaneous pneumothorax was 19 cases and secondary spontaneous pneumothorax was 38 cases. The underlying pathology in secondary spontaneous pneumothorax was tuberculosis emphysema and chronic obstructive pulmonary disease in 35 cases. The indications of thoracotomy were persistent air leakage in 23 cases recurrent pneumothorax in 21 cases, inadequate expansion in 13 cases. Rupture of bullae or blebs were most frequent operative and pathologic findings in persistent air leakage group and recurrent pneumothorax group. In inadequate expansion group, predominant finding was destructive lung lesion. Bullectomy and/or bullae ligation was most effective procedures in 36 cases [63%] for operative management of spontaneous pneumothorax. Duration of preoperative and postoperative chest tube indwelling day was 13.35 days and 8.05 days in persistent pneumothorax group, 8.92 days and 7.77 days in recurrent pneumothorax group, 13.23 days and 10.21 days in inadequate expansion group.

목적 만성폐쇄성폐질환의 CT에서 자동 정량 측정된 체성분과 폐기능 또는 정량적 변수들 사이의 연관성을 알아보고자 하였다. 대상과 방법 총 290명의 만성폐쇄성폐질환 환자를 대상으로 연구하였다. 흉부 CT에서 근육 및 피하지방 부피, T12 레벨에서 근육 및 피하지방 면적 및 골 감쇠를 딥러닝 기반 분할 알고리즘을 사용하여 획득하였다. Parametric response mapping-derived emphysema (이하 PRM^emph), PRM-derived functional small airway disease (이하 PRM^fSAD) 및 기도 벽 두께(airway wall thickness; 이하 AWT)-Pi10을 정량적으로 평가하였다. Pearson 상관 분석을 사용하여 체성분과 결과 간의 연관성을 평가하였다. 결과 근육과 피하지방의 부피와 면적은 PRM^emph와 PRM^fSAD와 음의 상관관계를 보였다(p < 0.05). T12에서의 골밀도는 PRM^emph와 음의 상관관계를 보였다(r = -0.1828, p = 0.002). 피하지방의 부피와 면적과 T12에서의 골밀도는 AWT-Pi10과 양의 상관관계를 보였다(r = 0.1287, p = 0.030; r = 0.1668, p = 0.005; r = 0.1279, p = 0.031). 반면에 근육 부피는 AWT-Pi10과 음의 상관관계를 보였다(r = -0.1966, p = 0.001). 근육 부피는 폐기능과 의미 있는 연과성을 보였다(p < 0.001). 결론 흉부 CT에서 정량적으로 평가된 체성분은 만성폐쇄성폐질환의 표현형 또는 중증도와 연관성을 보인다.
