Although the operation for the ventral lesion of craniovrtebral junction and atlantoaxial area is considered difficult to perform, the transoral approach made it safer and easier. The authors report 10 cases(9 patients) treated by the transoral approach for the lesion of craniovertebral junction over the past 13 years at the Ajou University Hospital and the Presbyterian Medical Center. Of these 10 cases, there were 4 odontoid type II fractures, 1 atlantoaxial dislocation, 1 os odontoideum, 1 chordoma at lower clival area, 1 rheumatoid arthritis, 1 epidural abscess and 1 wound revision due to slippage of grafted bone after clivoaxial fusion. The surgical methods included 4 cases of anterior decompression and clivoaxial fusion, 2 cases of anterior decompression and C1-2 interarticular joint fusion, 1 case of anterior decompression and clivoaxial fusion followed by posterior fusion, and 3 cases of anterior decompression and posterior fusion. In nonreducible atlantoaxial dislocation or ventral cord compression le sion, if the clivoaxial angle was less than 120 degree, the transoral approach was selected. The appropriate surgical approach must be selected according to the degree of compression of the neural tissue involving the craniovertebral junction and atlantoaxial dislocation.

In order to evaluate the genotoxic hazard among workers potentially exposed to low level petrochemical substances, the analyses of micronuclei (MN) and sister chromatid exchanges (SCEs) in lymphocytes were performed in 46 male workers (as exposed group) and 46 nonexposed subjects (as control group). Mean frequencies of MN and SCEs (respectively, 12.9/1000 cells and 6.5/cell) in exposed group were very significantly higher than those (10.2/1000 cells and 5.4/cell) in control group. And there were also significant differences in mean frequencies of MN and SCEs adjusted for age, employment duration, smoking, and drinking between two groups. Median frequencies of MN and SCEs in exposed group were very significantly higher than those in control group. Frequencies of SCEs were higher in smokers than in non-smoker. Frequencies of MN in smokers, however, were similiar to those of non-smoker. Interaction between exposure and smoking on MN and SCEs induction was not observed. The results suggest that there is genotoxic hazard in high risk group like workers handling carcinogens in petrochemical plants and the analyses of MN and SCEs are useful biomarkers for the exposure to hazard substances even at the level below the exposure limit.

BACKGROUND: This study was carried out to evaluate the efficacy of desferrioxamine as a chelating agent in iron overloaded patients with severe aplastic anemia due to multiple transfusion. METHODS AND MATERIALS: From Oct. 1995 to Aug. 1996, 15 patients with aplastic anemia, diagnosed from May 1995 to Jan. 1996 at St. Mary's Hospital, who had a transfusional hemosiderosis were included in this study. They received 19 courses of high-dose desfer-rioxamine therapy for 6 days(20 to 30 mg/kg daily as a 24-hour intravenous infusion) . Before and after treatment, we measured serum ferritin, iron, TIBC, 24-hour urinary excretion of iron. RESULTS: 1) The range of iron load before treatment was between 4.5 and 20.0 gram. 2) Because of limit of detection(1,800 microgram/L), it was difficult to compare the changes of serum ferritin level after therapy to those of before therapy. 3) There was no significant differences between the levels of serum iron before and after therapy(214.3+/-62.8 vs 220.0+/-53.3). And there was no significant differences between TIBC before and after therapy(235.8+/-64.6 vs 259.4+/-60.1). 4) Iron/TIBC ratios were significantly deceased after desferrioxamine treatment compared to those of before therapy(0.90+/-0.04 vs 0.85+/-0.04, P<0.001) and mean urinary excretions of iron were increased by high-dose desferrioxamine compared to those by test dose(6.5+/-7.6 vs 29.1+/-14.3, P<0.001) CONCLUSION: High-dose desferrioxamine therapy is very effective for chelating and excretion of iron in iron overloaded patients with severe aplastic anemia due to multiple transfusion. A repeat administration of desferrioxamine is necessary for the iron overloaded patient to eliminate the risk of a transfusional hemosidersis.

BACKGROUND: In women, the prevalence of depression is known to be more than twice as high as in men. Because many depressive women complain of their somatic symptoms instead of neurovegetative ones, many cases of depression have been misdiagnosed. Women also tend to use medicine more frequently than men do to manage depression. So we investigated the relationship between somatic symptoms and drug use in housewives for better management. METHODS: From 1st. March to 31st. March in 1996, the prepared questionnaires were presented to housewives living in the area of Kyung-ju city, who responded the questionnaires under direct interview. The questionnaire was composed of two parts. One part included demographic data, somatic complaints, drug use, places of drug purchase, current diseases that had been diagnosed by doctors. The other included Korean standard Beck Depression Inventory-questionnaire. The subjects were divided into two groups by BDI score(21 point), which was the cut-off point for depression in Korea. The relationships of somatic symptoms and drug use between the two groups were analyzed. RESULTS: There were 110 housewives who had depressive trends among 569 respondents. In general characteristics, there was significant difference between the two groups except the item of religion. In the items of somatic symptoms, there were more somatic symptoms in the group of high BDI score(>_21) except fatigue(P<0.01). More drug users were found in the group of high BDI score(>_21) (P<0.05). In the group of high BDI score(>_21), there was definite correlation between the items of somatic symptoms and drug use. There was no difference between the two groups in the item of drug purchase site. The most common site of drug purchase was the drug store in both groups. CONCLUSIONS: Depressive housewives complained of more somatic symptoms and more often used drugs as well.

OBJECTIVE: For the treatment of carotid cavernous fistula(CCF), transarterial detachable balloon occlusion(DBO) is the method of choice. When it has failed to occlude the fistula, various embolization methods are used to treat the fistula. Transvenous embolization through the superior ophthalmic vein(SOV) is another method of treatment. The venous approach through the SOV after surgical dissection and exposure of this vein has been recommended by some delete, but(here) delete delete(an) alternative treatment method by percutaneous puncture of the SOV without surgical dissection(is described). METHODS: A 19-year-old woman admitted to our hospital two months after accident, presented with proptosis, chemosis, occulomotor and abducens nerve palsies, and bruit of the right eye. The authors tried DBO via transarterial route in initial treatment and the fistula was occluded with subsequent disapearance of bruit. However, 2 weeks later, she complained of recurence of bruit. Transarterial approach was attempted again, but the fistula hole was too small for this approach. The venous approach via SOV by percutaneous puncture was then tried. Puncture was made at the medial one third of the superior orbital rim and the fistula was embolized with Guglielmi detachable coils (GDCs). RESULTS: The fistula was completely occluded and no early and late complications noted. The patient's clinical symptoms were improved within a few days. CONCLUSION: Treatment of CCF by percutaneous puncture of the SOV is an alternative and effective method when other approaches are not feasible.

The aim of this study was to compare optic disc size obtained using the two methods Color polaroid photographs of optic disc of 130 normal subjects and 174 patients with glaucoma were evaluated by means of computeraided morphometry. In the first method, the optic disc size were calculated by applying the modified formula of an ellipse, where area=pi/4xthe horizontal diameterxthe vertical diameter. In the second method, we obtained optic disc size [] using the twelve radii that were measured every 30 degrees. Magnification effects of the eye and camera were corrected in the two methods. The measurements of the optic disc area(2.49mm2), cup area(1.01mm2) and neuroretinal rim area (1.49mm2) by the first method were significantly(P<0.003, Wilcoxon signed -rank test) different from the measurements by the second method(2.48mm2, 1.03mm2, 1.45mm2, respectively) (the average difference; 0.05+/-0.05mm2, 0.05+/-0.05mm2, 0.07+/-0.06mm2,respectively). The mean error for the neuroretinal rim area was 4.2+/-3.3% in the normal group and 7.5+/-8.5% in the glaucoma group(P=0.005). It increased with decreasing neuroretinal rim area and increasing visual field defects. Thus the magnification corrected measurements of the horizontal and vertical diameters and the modified formula of an ellipse can be used for a quick approximate estimation of the optic disc size, but cannot replace more accurate method of optic disc measurements using twelve radii.
