Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin-1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-alpha release from IL-2-activated T-cells. A 13-year-old male patient visited our hospital with abdominal pain. He was diagnosed with acute lymphoblastic leukemia(T cell type) by bone marrow study on his 2 nd day in hospital. On the 3 rd day of induction chemotherapy(prednisone, L-asparaginase, vincristine, intrathecal methotrexate), pulmonary edema and pleural effusion, ascites and generalized edema developed and lasted for 53 days without responding to supportive care. The laboratoy finding was that TNF-alpha was increased without evidence of infection and hypoalbuminemia was noted. It was suggested that the patient's clinical feature was induced by VLS.

PURPOSE: To recanalize the occlusive lesion of superficial femoral artery at origin site by retrograde approach via popliteal artery. MATERIALS AND METHODS: 15 patients, who were poor surgical candidates due to coronary artery disease and who had severe occlusive lesion of superficial femoral artery close to its origin with good distal runoffs to popliteal artery, were selected. Patients were all~men and range of age were from 53 years to 66 years (mean age:63 years). Range of lesion length were from 15cm to 30cm (mean length:22.4cm). Localization of popliteal artery was done with Doppler stethoscope or "road-map" DSA. The method of recanalization were transluminal endarterectomy catheter (TEC), TEC and angioplasty, thrombolysoangioplasty (TLA). RESULT: Retrograde puncture of popliteal artery were done in 15 patients successfully. TEC & PTA was performed in 9 patients, TEC only in 2 patients, and TLA & PTA in 2 patients. During the follow-up period of 5 months to 2 years reocclusion did not occurr in 10 patients except for 1 patient with poor cardiac output in whom it occured 1 day later. Remained 4 patients were lost in follow up. Any neurologic or vascular complication did not occur. CONCLUSION: Retrograde approach of superficial fernoral artery via popliteal artery in patients with difficult vascular intervention by common method provides a useful, alternative recanalization method.

In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

Percutaneous transluminal angioplasty(PTA) were performed in three patients with atherosclerotic stenosis of subclavian arteries. The arteries were successfully dilated without complications during the procedure. All patients were asymptomatic during follow-up periods ranging from eight months to fifteen months after PTA.
