Intramedullary spinal cord metastases (ISCM) account for only 3.4% of symptomatic metastases to the spinal cord. The survival of patients with ISCM is characteristically short, often no longer than 2 months, due to a rapid neurologic deterioration and the presence of widespread metastases, including metastases to the brain. We report two cases of ISCM arising from primary sphenoid sinus carcinoma and primary lung cancer along with a review of the literature. The case of ISCM from the primary sphenoid sinus is the third case of secondary syringomyelia due to ISCM in the world literature, and ISCM from the primary lung cancer is the first case reported in Korea. One case showed a slow progression of symptoms and a longer survival (26 months after the radiotherapy to the spine), and the other showed a rapid deterioration of symptoms with a shorter survival. More effective palliation can be achieved if the disease is diagnosed at an early stage when the neurologic deficits are still reversible.

OBJECTIVE: To evaluate the maternal complications and perinatal outcomes in twin pre-gnancies with one fetal demise PATIENTS: From January 1990 to December 1996, 20 twin pregnancies with single fetal death were observed in Seoul National University Hospital : in 6 cases(group 1) between 20 ~26 weeks and in 14 cases(group 2) after 26 weeks gestation by gestational age of fetal death ; in 7 cases of monochorionic and in 13 cases of dichorionic placentation. RESULTS: The incidence of one fetal death was 5.4% in twin pregnancy. Diagnosis-to- delivery interval of group 1 was longer than group 2(61.0 days : 8.9 days). So it was thou- ght that the gestational age of delivery in group 1 was not always earlier than in group 2. And other parameters(chorionicity, preterm delivery, cesarean section, coagulopathy, IUGR, perinatal mortality, neurologic sequelae, IVH) didn't show the statistical differences between group 1 and group 2. According to chorionicity, it seemed that the perinatal mortality rate of monochorionic group was higher than dichorionic(86% : 62%) and that cesarean section rate was higher in dichorionic group(54% : 14%). But there were no statistical significances between two gruops. All other parameters also didn't show differences statistically. CONCLUSION: We fail to demonstrate that monochorionic placentation is associated with increased risks for the survivor in twin pregnancies of single fetal demise. It may be part- ially explained due to small numbers of cases in this study.

Nickel is widely known as a common source of contact dermatitis and nickel sensitivity amounts to nearly 10 percent of allergic contact dermatitis patients. Common sources of nickel dermatitis are well known as necklaces, watches, rings, hooks, earrings and spectacle frames. Recently, we have seen five cases of nickel dermatitis the suspected sources of which were metal spectacle frames. The interim patch test result in our occupational and environmental clinic suggests that the metal spectacle frame is one of the most common sources of nickel dermatitis. Out of 84 medical students 27 wore metal spectacle frames. We have done a dimethylglyoxime spot test to the metal spectacle frames and got a positive result in 12 out of 27(44.4%). We conclude that metal spectacle frame seems to be one of the dominant causes of nickel dermatitis and it will be an increasing problem in our society.

This study was undertaken to observe the difference of patch test and prick test positive reactions in three groups, 20 atopic dermatitis patients, 20 chronic urticaria patients, and 20 normal controls, Twenty commercial antigens (ToriiCo.) and twenty three frozen and boiled antigens of fishes and shellfishes were used as test materials. The results were as follows: 1. No positive reaction was observed in all sixty subjects in patch test. 2 In prick test, difference in reactivity was observed among atopic dermatitis (14. 7%), chronic urticaria (8.7%), and normal control(1. 5%) 3. There was significant difference in reactivity between Torii and frozen antigens in atopic dermatitis group, but no significance in chronic urticaria and control groups. 4. Boiling altered the reactivity in tested materials in all three groups of subjects singificantly. 5. Patients with past or family history of allergic diseases showed double fold higher reactivity tban patients without any history.

The pinch graft is one type of skin graft and is indicated in small, chronic stubborn wounds or ulcers where cosmetic results are not paramount. It is a common procedure for the rapid healing of leg ulcers in countries where these are very common, such as in western society. However, it is an unfamiliar procedure to dermatologists in Korea where leg ulcers are quite rare. We treated a case of leg ulcer in systemic sclerosis using pinch grafts with satisfactory results. The pinch graft may be a useful treatment method for skin ulcers in dermatologic surgery under adverse conditions.

Low back pain patients an controls of shipyard workers were surveyed between June 1995 and september 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

Recent development in thepolymerase chain reaction (PCR) has brought an extraordinary opportunity for the rapid detection of M. tuberculosis in clinical specimens for the diagnosis of tuberculosis. Pneumoconiosis is a sort of pulmonary fibrosis consequent to inhalation of the respirable dust. The association between pulmonary tuberculosis and pneumoconiosis is well recognized. There is a 10-fold increase in the tuberculosis risk among the workers who have pneumoconiosis demonstrated by chest roentgenogram. The physicians managing the patients with pneumoconiosis have to maintain a high index of suspicion for the development of mycobacterial infection, since the diagnosis of tuberculosis is often difficult. Mycobacterium tuberculosis is a very slow growing organism and acid-fast bacillus (AFB) staining frequently shows false negative results, and therefore PCR would be a very rapid, easy and sensitive diagnostic method for the diagnosis of Mycobacterium tuberculosis in pneumoconiotic patients. To compare the PCR method with the conventional methods in diagnosing Mycobacterium tuberculosis in sputum, we used the sputa of 115 pneumoconiosis patients in Munkyeong Cheil Hospital. Of 32 pulmonary tuberculosis in the pneumoconiosis patients, 29 were PCR positive and were higher than 28, 20 positive by culture and AFB stain. Overall sensitivity, specificity, and which were 90.6, 91.5 % respectively for the PCR assay, 87.5, 100 % for the culture method ; 62.5, 98.7 % for the AFB stain. The PCR assay is a rapid, efficient, sensitive method which can detect M. tuberculosis directly in pneumoconiosis patients, and further study should be followed for the development of the easier method.
