458 female workers working in the small and medium scaled industries in Inchon area were surveyed to study their general characteristics, health behavior, working and environmental conditions, current health status etc. Self-administered questionnaire was developed by authors and distributed to the female workers with the explanation by trained interviewer on the purpose of survey and the method how to answer. The results were as follows: t. General characteristics showed that most(75.3%) of workers were living in their own home, and their age distribution was relatively even from teenagers to the forties. The level of education was high school graduate(including drop-out) in 69.4%, suggesting that the education level of female workers was increasing gradually. The marrital status was 69% in unmarried, and 31% in married state. 2. Survey on their health status showed that more than 20% of female workers complained that they have some kind of disease and most of them complained that they have chronic symptoms more than three kinds. Also, they complained at least two or three symptoms in physical, mental or sensoryneural symptoms respectively. But their medical care utility rate was only 22%. 3. There were no significantly correlated variables between health status and general characteristics(by x2-test). Among the variables on the health behavior, only alcohol drinking was significant to health status. Perceived health status related to the working environment was significantly different to the degree of work satisfaction and awareness for the exposure to harzadous materials. 4. Multivariable analysis showed that work satisfaction, awareness for the exposure to harzadous materials, alcohol drinking, type of employment were significantly related to the physical or mental health index, and also marrital status was to the physical health index. Work satisfaction, awareness for the exposure to harzadous materials, marrital status were related to the sensoryneural health index. Alcohol drinking, work satisfaction, awareness for the exposure to harzadous materials, marrital status were significantly related to the number of complained chronic symptoms. In summary, this study showed that inspite of wide and various range of the general characteristics of female industrial workers in Korea comparing to the past, there was high prevalence of disease due to the poor working conditions and low work satisfaction etc. Therefore, more detailed disease preventive policies or improvement of the work environment, and systematic management to raise the work satisfaction of female workers are urgently needed. And also, occupational health policies increasing the access to health care to provide the adequate health service for the workers who have perceived need are necessary.

Objective: Cerebral white matter changes (WMCs) and silent brain infarcts (SBIs) are common radiological findings in neurologically asymptomatic elderly people. Their presence is associated with an increased risk of stroke or dementia. Homocysteine (Hcy) can cause atherosclerosis and may thus act as a useful marker of stroke prior to symptom onset. This study aimed to evaluate the utility of Hcy as a surrogate marker for early intervention for stroke in community-dwelling healthy elderly persons with cerebrovascular lesions such as WMCs and SBIs. Methods: We assessed the relationship between the Hcy level and presence of WMCs/SBIs on brain computed tomography (CT) in 554 elderly individuals aged ≥65 years with no history of stroke or dementia. Results: The mean age of the participants was 74.43±7.32 years. Of the 554 patients, 106 (19.1%) had WMCs and/or SBI findings on brain CT. The mean Hcy level was higher in participants with WMCs/SBIs (P=0.001). The WMCs/SBIs group had a significantly greater number of participants with high Hcy levels than the non-WMCs/SBIs group (P<0.001). High Hcy levels (≥12.3 μmol/L) was significantly associated with WMCs and SBIs even after adjusting for age, Korean Mini Mental Status Examination score, education level, and vascular risk factors such as hypertension, diabetes, hyperlipidemia and smoking status. Conclusion: The result of our study suggests that regular monitoring of homocysteine level as a modifiable risk factor may be helpful for predicting the association of cerebrovascular lesions such as WMCs and SBIs for the prevention of future ischemic stroke and cognitive impairment.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.

OBJECTIVE: We analyzed the clinical features of amniotic fluid embolism confirmed by autopsy or clinical dicision for making a plan of rapid diagnosis and intensive emergency care. STUDY DESIGN: We experienced 2 clincal cases in Ewha Mokdong Hospital and Severance Hospital at 1995, and reviewed the medical record & autopsy report of 15 cases in National Institute of Scientific Investigation from Jan, 1991 to Dec, 1995. RESULTS: The mean maternal age was 31+/-3 years. The mean gestational age was 40+/-1 weeks. The number of delivery were 1.4+/-0.8. The number of abortion history. were 2.6+/-2. The sexuality of fetus were six males (35 %), five females (29%), and unknown six cases (35 %) and the fetal mortality rate was 29 % (5 cases). The initial clinical symptoms and signs were hypotension (12 patients, 71%), vaginal bleeding(ll patients, 65%), cardiac arrest (6 patients, 35 %), dyspnea (5 patients, 29 %), and seizure (2 patients, 12%). In the case of normal spontaneous vaginal delivary (NSVD), the symptoms occurred during induction in 3 (18%), during delivery in 1 (6%), and after delivery in 9 (53%). In the case of Cesarean section, the symptoms occurred during section in 2 (12%), and after section in 1 (6%). There are one case whose symptoms occurred during 3rd gestational period. CONCLUSIONS: We should alert for the amniotic fluid embolism in the clinical findings of acute collapse and vaginal bleeding, respiratory symptoms, and seizure at any peripartum. With eary suspicion of this disease and aggressive intensive care we can reduce amniotic fluid embolism mortality rate and it's legal problem.

A 26-year-old man with a one-year history of asthma and sinusitis presented with bilateral pleural effusions, patch basilar infiltrates on a chest x-ray and a pericardial effusion on an echocardiogram. The peripheral blood showed marked eosinophilia. An obstructive pattern was also observed during the pulmonary fuction test, which was responsive to bronchodilator inhalation. Nerve conduction studies showed right sural neuropathy. Thoracentesis yielded an acidotic exudative effusion with low glucose, low C3 and eosinophilia. An open lung biopsy revealed an eosinophilic interstitial pneumonitis associated with a necrotizing eosinophilic vasculitis, and granulomatous inflammation foci. In the literature, pleural effusions were reported in 29 percent of Churg-Strauss patients, but the number of effusions was low and their characteristics have not been well described. This report describes the characteristic findings of pleural fluid and its histologic features in a case of classical Churg-Strauss syndrome.
