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.

The PFC (Press Fit Condylar) knee was first implanted clinically in 1984 with retention of posterior cruciate ligament. Thereafter PFC modular version had been developed at 1988 with option of posterior cruciate ligament substitution and minor design changes. We classified the 170 patients, 252 knees which underwent the PFC total knee arthroplasty in the period from January 1988 to May 1995 into three groups. In group I, 62 patient. Had 93 total knee arthroplasties with insertion of the original PFC total knee prosthesis with retention of posterior cruciate ligament from January 1988 to October 1991. In group Iia, 51 patients had 74 total knee arthroplasties with insertion of the modular PFC total knee prosthesis with retention of posterior cruciate ligawient from November 1991 to May 1995. In group III, 57 patients had 85 total knee arthroplasties with insert.ion of the modular PFC total knee prosthesis with substitution of posterior cruciate ligament from November 1991 to May l995. Average follow-up periods were 7 years 5 months in group I and 3 years 2 months in group Iia and Ilb. Clinical and radiographic results were similar among the group I, Iia and llb except slight better scores in group Iia and Iib than group I, even though group IlI and IlI had short follow-up periods, Postoperative implant wear was developed at 5 knees in group I, 1 knee in group Iia and not developed in group Ilb. Implant loosening was developed at 1 knee only in group 1. Revisional arthroplasty was performed to 7 knees in group I, 1 knee in group Iia and not in group 1Ib. In conclusion, posterior cruciate ligament substitution group had no difference in functional results with the retention group. In the problem of implant wear, posterior cruciate ligament substitution group was superior to the retention group but similar in loosening.

The incidence of uterine prolapse during pregnancy is rare. A 34-year-old G3P1 was initially presented at 16 weeks 5days of gestation with a prolapse of the uterine cervix. The cervix was edematous and protruding beyond introitus. Management included bed rest, and the patient was discharged after several days with a vaginal pessary to help maintain cervical placement. At 35 weeks of gestation, the patient did not experience any further prolapse after the removal of the pessary. Pregnancy progressed to term with no further prolapse. She was readmitted at 38weeks 5days of gestation with spontaneous labor. She delivered a 3.36kg male with an Apgar score at 1 minute and at 5 minutes of 7 and 8 respectively. The patient's cervix remained prolapsed in the early postpartum period; however it was easily reduced prior to discharge. After puerperium, the patient's cervix remained prolapsed. She was fitted with a vaginal pessary for uterine support. We reported this case with related literature.

A 65 year-old male had chest pain which was diagnosed as unstable angina needing urgent coronary artery bypass surgery. Physical examination demonstrated signs of severe anemia and hemoglobin level was 5.7 g/dL. Gastrofiberscopy showed a 4 cm sized fungating mass at the lesser curvature with active bleeding. The mass was adenocarcinoma by pathologic examination. Simultaneous coronary artery bypass surgery and total gastrectomy were planned due to bleeding of the mass. Off-pump coronary bypass grafting was done first, followed by total gastrectomy. The postoperative course was smooth. He was discharged from the hospital after 12 days and was on surveillance for 9 months. We report a rare case of simultaneous surgery for angina and gastric cancer.

BACKGROUND: Although the effect of clonidine, an alpha2 adrenoreceptor agonist, is well established, there is no study to evaluate the effects of addition of clonidine to ldegrees Cal anesthetics in elderly hypertensive patients. The aim of this study is to evaluate the effects of addition of clonidine to ldegrees Cal anesthetics in elderly hypertensive patients undergoing senile cataract surgery. METHODS: Forty elderly hypertensive patients who scheduled for elective senile cataract surgery were divided into two groups. The control group (n=20) received oral diazepam 0.1 mg/kg 60 min before surgery and the clonidine group (n=20) did not received premedication. A mixture of 2% liddegrees Caine and 0.5% bupivacaine with normal saline 0.7 ml (control group) or clonidine 100 ug (clonidine group) was used as a ldegrees Cal anesthetics. Perioperative blood pressure, heart rate, sedation score, and intradegrees Cular pressure were measured. RESULTS: After anesthesia, there was a significant fall in blood pressure and intradegrees Cular pressure in clonidine group, and increase in sedation score in clonidine group than control group. There was no difference in the perioperative heart rate between the two groups. CONCLUSIONS: The above results show that addition of clonidine to ldegrees Cal anesthetics in elderly hypertensive patients undergoing senile cataract surgery produced reduction in blood pressure, intradegrees Cular pressure and produced intraoperative sedation.

PURPOSE: The aim of this study was to evaluate growth status using the insulin-like growth factor-I (IGF-I) and IGF-binding protein-3 (IGFBP-3) concentrations in children with subclinical hypothyroidism (SCH). METHODS: The study included 93 SCH patients (33 males and 60 females, age 8.1+/-1.9 years) and 94 healthy control subjects (31 males and 63 females, age 8.0+/-0.7 years). Patients' height and weight were measured, and their body mass index (BMI) and Z-scores were calculated. The relationship between growth parameters, including IGF-I and IGFBP-3 concentrations and thyroid functions (thyroid-stimulating hormone (TSH) and free thyroxine 4 (fT4) was explored. RESULTS: Although weight and BMI were greater in SCH patients, the Z-score of height, weight and BMI, and serum IGF-I and IGFBP-3 levels in SCH children were not significantly different compared to the control. In SCH patients, TSH showed a negative correlation with weight Z-scores (r=-0.23, P=0.028) and BMI Z-scores (r=-0.21, P=0.048). FT4 showed a positive correlation with IGFBP-3. CONCLUSION: The positive correlation of fT4 and IGFBP-3 and the negative relationship between TSH and weight and BMI Z-scores in SCH children suggest that subnormal thyroid functions could be related to growth impairment.

White pupil is one of the most disturbing problems in the pediatric age group and many conditions can cause white pupil, but the differential diagnosis between the retinoblastoma and other conditions simulating it, is the prime importance in the evaluation of the white pupil. The ophthalmoscopy is the most accurate diagnostic method for evaluating intraocular diseases because it is able to see directly. However, its usefulness seems to be limited in the case of extreme lens opacity or vitreous opacity and in the evaluation of orbital diseases extending outside of the globe. Recent advances of high resolution computed tomography(CT), the axial tomographic images of the orbit were markedly improved and represented good anatomic details of the orbit and the topographic relationship with surrounding structures. We reviewed CT findings of 15 children who presented white pupil and had results demonstrating specific findings in the cases of retinoblastoma, persistent hyperplastic primary vitreous and vitreous opacity due to retinal detachment and retrolental fibroplasia. The CT findings of each disease are discussed with detail.
