Aortopulmonary fistula is an exceedingly rare vascular malformation. It is commonly derived after chest injuly or from complication of chest operation and aortic dissection and congenital aortopulmonary fistula is only several cases combined with Tetralogy of Fallot or aortic stenosis. But a congenital aortopulmonary fistula without any hemodynamic abnormalities was not reported. A 56-year old man with exertional dyspnea was admitted. In an examination on admission, there were no abnomalities. Aortography showed an aortopulmonary fistula that branches from the ascending aorta adjacent to the right coronary artery, running to the main pulmonary artery. Transcatheter coil embolization was performed and he was discharged 7 day after embolization without complication. Exertional dyspnea disappeared and careful follow up has be performed periodically.

We evaluated the renal function could be estimated by the visual analysis of the perfusion images of Tc-99m DTPA renal scan. Renal scan, creatinine clearance(CCr) and serum creatinine(s-Cr) were obtained in 105 patients. Intensity of renal activity(RA) at 6 sec perfusion image after the first visualization of abdominal aortic activity(A or A) was considered as the parameter for estimating renal function. Intensity of RA was scored from grade(Gr.) 1 to 3(Gr. 1: RAsplenic activity(SA), Gr. 2: RA A or A, Gr. 3: RA60 mL/min. The P.P.V. of Gr. 2 RA was 92% for s-Cr from 1.5 to less than 3.5mg/dL and 83% for CCr value from 20 to less than 60mL/min. The P.P.V. of Gr. 3 RA was 95% for s-Cr3.5mg/dL and 95% for CCr<20mL/min. As the intensity of RA of perfusion images decreased, renal function more decreased. We could detect renal dysfunction by visual analysis of perfusion images of renal scan.

One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.

It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

The concept of workers' participation in occupational health was introduced to Korea recently in relation to primary health care in occupational health. But there is confusion and debate about workers' participation concept. The purpose of this study was to review the concepts of workers' participation and to conduct evaluation the workers' participation status in occupational health and safety. 394 workers and 54 employers (5.6%) in north area of Kyunggi-Do, were selected and interviewed with a questionnaire by a trained interviewer from August to September 1990. In general, the concept of workers' participation is based on industrial democratization and Declaration of Human Rights which had been powerful ideologies in labor movement. Contrary to workers' participation, community participation is rooted in the Health Rights. So, it is necessary to consider concept of workers' participation to improve participation. The results of survey were as follows: 1. Most of companies (71.75) carried out occupational health education to workers in study area. 2. The Occupational Safety and Health Committee (OSHC) were set up in 24.1% among the study companies, and 72.7% of workers among respondents thought that OSHC was helpful to workers health. 3. The workers signed his name to personal health report in 43.1% and the rate of participation in occupational environment examination was 54.9%. 4. The workers prefer the OSHC (39.3%), owner (35.1%) and union (25.8%) as a occupation health organization, but owners prefer OSHC (54.5%), manager (43.2%) and union (2.3%). 5. Among the factors of the general characteristics, the existence of labor union was a major determinant of workers' attitude and level of workers' participation. As we have seen, most levels of workers' participation are low in occupational health. The variable of existence of labor union among the factors was a major determinant of workers attitude and level of workers' participation. Therefore, in order to promote workers health, it is necessary to ponder long deeply on occupational health care system under the viewpoint of workers' participation.
