2.Dosimetry and MIRD for Re-188 Liquid Balloons.
Korean Journal of Nuclear Medicine 1999;33(2):222-227
Re-188 is suitable for endovascular liquid-balloon brachytherapy for the prevention of restenosis after angioplasty. Re-188 was concentrated to 3700 MBq/ml and labeled with DTPA. According to dosimetric calculation, it took 420 seconds using Re-188 solution with concentration of 3700 MBq/ml to irradiate 17.6 Gy to the target at 1 mm from the balloon surface. Software was made to estimate the irradiation time. MIRD calculation with dynamic bladder model yielded the whole body dose of Re-188-DTPA as 0.005mGy/MBq in case of balloon rupture and release of the whole amount into the blood.

INTRODUCTION: REM sleep which shows characteristic muscle atonia and increased resistance of upper respiratory track is known to be vulnerable to sleep apnea. Previous studies reported that REM sleep-dependent (or related) obstructive sleep apnea syndrome (REM-dependent OSA) could be one of sleep disordered breathing. The present study aimed to investigate clinical findings and polysomnographic variables of REM-dependent OSA. METHODS: Fifty-six patients diagnosed with mild to moderate obstructive sleep apnea by overnight polysomnography (5

4.A Study on Subtypes of Thyroid Disorders Detected by Neonatal Screening Test.
Journal of Korean Society of Pediatric Endocrinology 1997;2(1):81-100
PURPOSE:The project of the neonatal mass screening test for inborn errors of metabolism are just at the beginning in Korea and there was a few reports about the overall incidence and subtypes of congenital hypothyroidism. METHODS:In this study, we analysed the 97 cases of newborns with hyperthyrotropinemia who were detected by neonatal screening test to identify the incidence and early clinical manifestations of each subtypes of congenital hypothyroidism. Thyroid function were measured by thyrotropin(TSH) level, T4, T3, Free T4, Free T3, thyroglobulin, T3 resin uptake, TBII, TBG in serum, thyroid ultrasonography and 99mTc thyroid scan. We reanalysed the thyroid functions 1 week after discontinuance of L-thyroxine treatment for 1 year. RESULTS: 1) The time of neonatal screening test were between 3 and 7 days after birth in 46 cases(47.4%) and 8 and 14 days after birth in 35 cases(36.1%). Two cases (2.1%) were done neonatal screening test at the age of 2 days old. 2) The major cause of thyroid disorders were primary hypothyroidism in 45 cases of the total due to thyroid aplasia(7 cases), thyroid hypoplasia(17 cases), ectopic thyroid gland(12 cases) and dyshormonogenesis(9 cases). Other causes of thyroid disorders were TBG deficiency(11 cases), TBG dysfuction(1 case), transient hyperthyrotropinemia(28 cases) and transient hypothyroidism(12 cases). 3) Serum level of thyrotropin(TSH) at diagnosis were 223.5+/-229.6microU/ml in thyroid aplasia, 41.6+/-42.9microU/ml in thyroid hypoplasia, 52.4+/-55.6microU/ml in ectopic thyroid gland. TSH levels were significantly high in thyroid aplasia. T4 levels in thyroid aplasia are 1.7+/-2.0microg/dl and this is significantly lower than other types of thyroid disorders. T3 levels were within normal range except in thyroid aplasia and TBG deficiency. 4) Prolongation of physiologic jaundice was the most common clinical manifestation(33.3%) in patients with primary hypothyroidism and macroglossia, hypothermia, umbilical hernia and cold skin were the next commom clinical manifestations in order to present. 5) Osseous development was normal in 57 cases(82.6%) out of 69 cases who accomplished roentgenographic examination of knees. Only 12 cases(17.4%) showed retardation of osseous development, but there was no significant differences between types of thyroid disorders. 6) Most of the newborn(93.3%) with primary hypothyroidism started to treatment within 8 weeks of age. 7) Initial dosage of L-thyroxine was 10microg/kg/day and decreased 6 to 12 months after treatment. 8) There was significantly decreased thyroid uptake of 99mTc after 1 year follow-up in 5 cases of dyshormonogenesis. 9) The serum TSH levels returned to normal ranges within 6 month after treatment in transient hypothyroidism and transient hyperthyrotropinemia. CONCLUSIONS:Special attention should be paid to transient hyperthyrotropinemia and transient hypothyroidism because many of the congenital thyroid disorders showed transient type and it is necessary to establish the diagnostic guideline to early detect these transient types of congenital thyroid disorders.

5.THE NEW CRUSH MODEL AND ITS PATENCY RATE ON THE RAT FEMORAL VESSELS.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1997;24(2):257-263
A new crush anastomosis model which can be evaluated as crush energy was established on the femoral artery and vein of the rats weighing 250g on the average. The degrees of vessel injury were evaluated as crush energy. The arteries underwent the crush injury with the energy of 0.3J, 0.4J, 0.5J, while the reins were crushed with the energy of 0.2J, 0.3J, 0.4J respectively then the vessels in each group were divided and anastomoses by a standard microsurgical technique. Saline and heparin were used as a luminal topical agent and systemic one, which allowed contact with the damaged endothelium. The heparin treated group had a patency rate of 95%(0.3J), 87.5%(0.4J), 40%(0.5J) vs. 55%(0.3J), 15%(0.4J), 10%(0.5J) in the saline irrigated group in the femoral arteries, which had the patency rate of 82.5%(0.2J), 72.5%(0.3J), 42.5%(0.4J) vs. 35%(0.2J), 12.5%(0.3J), 7.5%(0.4J) in the saline irrigated group in the femoral vein at 1 day. There was a energy-related decrease in patency rate. These findings indicate that the crush model of 0.4J in the rat femoral artery, 0.3J in the rat femoral vein is a reliable and reproducible thrombosis model. The model described in this study is to be used to evaluate and assess the ability of antithrombotic agent in preventing thrombosis at the anastomotic site.

Fracture of intercondylar eminerce of the tibia indicate probable alteration of the cruciate ligament stability in the knee and occur from hyperextension injury of the knee and violent internal rotation of the tibia. Fracture of intercondylar eminence of the tibia has been classified by Meyer and Mckeever(1959, 1970) according to the degree of displacment and this classification is important as it pertains to the proper selection of treatment. The author studied 24 cases in 24 patients of fracture of the intercondylar eminerce of the tibia at the Department of Orthopedic Surgery of Severance Hospital during a 10 year period from Januaary, 1975 until December, 1984. The aim of this study was to find out incidence, cause and associated injury of the fracture of the intercondylar eminece of the tibia and was to asses the comparative results of the conservative and surgical treatment. The result of this study ase as follows ; 1. There is a predisposition for make in a ration of 3:1 and there is no age preponderance in occurance. 2.Majority of cause of injury was traffic accident(62.5%). 3.Isolated fracture of intercondylar eminence of the tibia was 15 cases (62.5%) associated knee joint injury shows 9 cases (37.5%). Among the associated knee joint injury, rupure of medial collateral ligament was 4 cases(44.4%), rupture of medial meniscus was 3 cases(33.3%) and rupture of lateral colateral ligament was 2 cases (22.2%). 4.By Meyer and Mckeever's classification, Type 2(41.7%) fracture of intercondylar eminence of the tibia was most common, and then Type 1(37.5%) and Type 3(20.8%) occured in order of frequency. 5. Type 1 and Type 2 fracture of the intercondylar eminence of the tibia resulted in good prognosis with only conservative treatment, and open reduction is not indicated. 6. Type 3 fracture of the intercondylar eminence of the tibia can be treated with conservative treatment if there is no associated injury of the knee joint.

8.Salmonella Osteomyelitis of the patella: A Case Report
The Journal of the Korean Orthopaedic Association 1990;25(5):1572-1575
A 48 years old male was visited with complaining of painful swelling of the left knee joint for 2 weeks duration. On radiological finding of the patella, there was found local rarefaction and osteolytic change in the inferior pole. It was diagnosed as Salmonella osteomyelitis of the patella and was confirmed by bacteriological study. Osteomyelitis of the patella caused by Salmonella group C as an etiological factor has not been reported. It was treated by conservative method with satisfactory result.
