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.

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.

We performed twenty three cementless total hip arthroplasties(THA) on seventeen patients, all of whom were diagnosed with steroid-induced avascular necrosis of the hip (AVN). The average age of the patients was 41years, mean follow-up period was 41months (24-74months). The final average Harris hip score was 94 and overall results were excellent. On radiographic evaluation, 17 femoral components met the criteria for bone ingrowth(spot weld) but it was somewhat delayed. There was no evidence of loosening of the femoral and acetabular components. The results of this study suggest that long term steriod treatment does not prevent bone ingrowth. Cementless total hip arthroplasty appears to be a reasonable therapeutic option for steroid-induced avascular necrosis of the hip.

BACKGROUND: A and B transferase are glycosyltransferase that transfer N-acetylgalactosamine and D- galactose to H antigen, respectively and lead to the expression of A and B phenotypes in ABO blood group system. Reduced or no activities of serum A and B transferase were observed in some A and B subgroup individuals. Determining the activities of serum A and B transferase can be useful in discriminating rare A and B subgroups. MATERIALS AND METHODS: ABO typing, saliva test, adsorption elution test and serum transferase assay were performed on samples from 12 individuals showing ABO discrepancy or weakened cell typing reactions which were referred to the Seoul National University Hospital to confirm their ABO blood types. Serum transferase activity was assayed by determining the ability of serum to convert group 0 RBCs into A or B cells. RESULTS: Determination of serum ABO transferase activity was useful in the identification of Ael (3 cases), B. (2 cases), Bm (1 case), Am (1 case), Bx (1 case), 0 with weakened anti-A or anti-B (3 cases), and A without anti-B due to hypogammaglobulinemia (1 case). CONCLUSION: Determining serum A and B glycosyltransferase activity was proven to be a simple and useful tool for the classification of several ABO subgroups.(Korean J Blood Transfusion 10(1): 27-33, 1999)

BACKGROUND AND OBJECTIVES: Primary intervention by stent implantation during acute myocardial infarction is a novel strategy to provide better myocardial perfusion compared to thrombolysis or baloon angioplasty. We aimed to assess the reperfusion achieved by primary stenting, employing TIMI frame count for more objective and quantitative measurement. MATERIALS AND METHOD: Measurements for number of frames required to opacify standardized angiographic landmark branch(TIMI frame count) were determined for the coronary arteries of 77 normal controls and 65 patients with acute myocardial infarction who underwent primary stenting within 12 hours of symptom onset. RESULTS: In normal subjects, TIMI frame count for left anterior descending artery(LAD) was 1.3 times of mean count of right coronary artery(RCA) and left circumflex artery(LCx), and significant less than that of TIMI study(22.3+/-4.9 vs 36.2+/-2.6, p<0.05). TIMI frame count for RCA and LCx was similar to results of TIMI study. In infarct related arteries(IRA), corrected TIMI frame count(CTFC) after primary stenting was similar to those of normal control. Frame counts of RCA was larger compared to that of normal control, but statistically insignificant(23.0+/-7.5 vs 17.6+/-3.5, p>0.05). There was no difference of CTFC of non-infarct related arteries between patients and normal controls. CONCLUSION: The TIMI frame count of LAD artery in normal Korean subjects was significantly less than that of American counterpart. In patients with acute myocardial infarction, primary stenting appeared to provide improved coronary flow similar to that observed in normal subjects, as measured by TIMI frame counting.
