Purpose: The purpose of our study was to assess the clinical and radiological results of isolated acetabular revision and the differences in the results between monoblock and modular femoral stems. Materials and Methods: Between October 1991 and June 2002, 39 patients (39 hips) underwent isolated acetabular revisions with use of uncemented cups and bone grafts. The mean period of follow-up was 5 years 3 months (range, 2 years 1 month to 9 years 8 months). The mean age of the patients at the time of the surgery was 51 years old (range, 26 to 75 years old). The monoblock femoral stems were used in 19 hips and the modular femoral stems were used in 20 hips. The monoblock stems were retained without exchange provided that there was no gross scratch on the femoral head and the femoral stem was confirmed to be stable and fixed intraoperatively. In the modular stems, the femoral heads were always exchanged with new ones. Results: The mean Harris hip score improved from 57 to 87 points. Radiologically, all the stems retained at surgery remained well osseointegrated without osteolysis. Re-revisions of the acetabular components were performed in 5 hips using monoblock stems due to periacetabular osteolysis caused by excessive wear of polyethylene and subsequent loosening of the cups in 3 hips and mechanically unstable acetabular cups without osteolysis in 2 hips. The mean wear rate of polyethylene coupled with the monoblock stem was 0.27 mm/year which was greater than the 0.11 mm/year in the cases with modular stems. Conclusion: To prevent failure of acetabular cups that may occur later by excessive wear of polyethylene, we recommend revision of the well-fixed monoblock femoral stems even though there is no gross scratch on the femoral heads of the monoblock stems.

Turner syndrome with abnormalities of X chromosome is generally characterized by gonadal dysgenesis causing premature ovarian failure, primary and secondary amenorrhea. Premature ovarian failure is often caused by X chromosome aberrations. It has been shown that gross X chromosome abnormalities such as monosomy X usually result in primary amenorrhea and poor pubertal development, whereas mild X chromosome abnormalities such as partial X deletions usually lead to secondary amenorrhea and fairly good pubertal development. Fertility has been reported in several patients with relatively small Xq deletions before the onset of premature ovarian failure, and the X chromosome abnormality is often inherited by offspring. We describe a 46,X,del(X)(q26) female with normal pregnancy, in whom same karyotype was found in the fetus by amniocentesis. We report this case with brief review of related literatures.

BACKGROUND: We analyzed the changes in QT dispersion (QTd) in children with Kawasaki disease (KD), and determined the presence of repolarization abnormality in these children even in the absence of coronary artery abnormalities. METHODS: Ninety-one children with KD and 20 healthy controls were enrolled in this retrospective study. Serial echocardiographic and electrocardiographic (ECG) measurements in the beginning of treatment, 2nd month and 6th month after the diagnosis were compared. Fifty-one of 91 children had at least 2 serial ECG data. The number of patients who had 3 consecutive ECG data was 23. RESULTS: Among the 67 KD patients with no coronary artery changes, the consecutive mean QTd values were 41.86 ms, 37.84 ms, and 25.47 ms, respectively (26 ms for controls). In the analysis of changes among KD patients without coronary artery abnormalities, QTd showed a significant decrease with time (p=0.01). Especially, the 1st month and the 6th month QTd values were significantly different (p=0.028). The mean QTd values in KD patients with coronary artery changes were significantly higher than those in KD patients with no coronary artery changes at each time (1st, 2nd, and 6th month exam). CONCLUSION: QTd is significantly increased in children during the early stage of KD. Repolarization abnormality may exist during the acute stage of KD, regardless of the echocardiographic changes.

OBJECTIVES: To evaluate the patterns of changes in maternal weight and fetal weight discordance in twin pregnancies during consecutive gestational periods. METHODS: A retrospective chart review was done for a total of 148 twin pregnancies taken care of throughout pregnancies between February 2002 and May 2004. They were divided into two groups; group A consisting of 109 cases without postnatal complications and with no more than 25% twin weight discordance at birth, and group B consisting of 39 cases with more than 25% twin weight discordance. Both ultrasound examination and maternal weight measurement were conducted in the three gestational intervals; between prepregnant times to gestational age 18 weeks, between gestational ages 18 to 28 weeks, and from gestational age 28 weeks to delivery. RESULTS: Except for maternal weights, none of the pregnancy factors such as maternal age, parity, gravity, height, prepregnant weight, duration of pregnancy, natural or artificial pregnant status, gender and chorionicity showed any significant difference by means between the two groups. The maternal BMI of the group A vs. the group B at the first, the second, and the third period were 0.53+/-0.10% and 2.01+/-1.28%, 2.97+/-0.11% and 4.84+/-1.23%, and 3.29+/-0.16% and 2.15+/-0.63% respectively. Inter-twin weight discordances between the two groups were 8.29+/-0.67% vs. 11.26+/-1.25 %, 7.79+/-0.05% vs. 11.03+/-1.36%, and 9.07+/-0.55% vs. 32.79+/-1.13%, respectively. CONCLUSIONS: Although several factors that affect twin weight discordance may be considered, we showed that the pattern of maternal weight gain during the gestational period is associated with the estimated values of twin weight discordances in the first gestational period.

BACKGROUND: The relationship between infection of microorganism and atherosclerosis has been studied because the pathophysiology after infection is similar to those of cell injury and/or lipid theory. Although there are many reports which described the relationships between the infection of chalamydia pneumoniae and the atherosclerosis. In Korea, even the prevalence of chlamydia infection has not been studied yet. This study was purposed on the prevalence of chlamydia infection and it's correlation to atherosclerosis. METHODS: 235 subjects were enrolled and age and sex adjusted subjects were divided into two groups, normal controls (n=43), atherosclerosis (AS, n=90) group:coronary artery disease (CAD, n=61) and cerebrovascular disease (CVD, n=29). Serum total cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDL-C) were measured, LDL-cholesterol (LDL-C) was calculated. Serum IgG chlamydia antibody were measured by ELISA method. RESULTS: TG was significantly higher in AS (162.51+/-100.04 mg/dL vs 122.91+/-63.31 mg/dL, mean+/-SD, p=0.019), and HDL-C was significantly higher in controls (47.30+/-9.88 mg/dL vs 39.38+/-8.29 mg/dL, p<0A65A>0.01). Levels of LDL-C and TC were not statistical significant. Serum IgG chlamydia antibody was positive in 29.8% (70/235), 30% (27/90) in AS group and 28% in controls and there was no statistical significance between groups (p=0.804). CONCLUSION: In conclusion, there was no significant differences in positivity of IgG chlamydia antibody in AS compared with that of controls. Overall positivity of chlamydia antibody was lower in Korea than in other country. It is still controversial whether Chlamydia pneumoniae is a primary etiologic agent of atherosclerosis or not. This study could not demonstrate the relationship between chlamydia infection and atherosclerosis in Korea. The effectiveness and indications of antichlamydial antibiotics for prevention of cardiovascular complications in atherosclerosis and overall chlamydia infection in general population will be needed in large scale trials.

PURPOSE: DiGeorge syndrome (chromosome 22q11.2 deletion syndrome) is a syndrome of multiple congenital anomalies characterized by hypoplasia or aplasia of the thymus and parathyroid, cardiovascular malformation, immune deficiency, cleft palate, characteristic facial features, and hypocalcemia. Ocular findings of DiGeorge syndrome are posterior embryotoxon, retinal vascular tortuosity, strabismus, ptosis, amblyopia and tilted optic disc. The authors present a case of DiGeorge syndrome with ocular manifestation not reported previously in Korea. Case summary: A six-year old female diagnosed with DiGeorge syndrome was referred to the authors' department within the hospital. The chief complaint was blurring vision in both eyes. Best corrected visual acuity of the right eye was 0.5 and of the left eye was 0.63. Cycloplegic refraction revealed high hyperopia and astigmatism in both eyes (OD: +7.25 Dsph; -2.5 Dcyl axis 180degrees, OS: +6.25 Dsph; -3.75 Dcyl axis 180degrees). In addition, hypertelorism, ptosis and tortuous retinal vessels during fundus examination were noted. CONCLUSIONS: Upon the initial diagnosis of DiGeorge syndrome in children, a comprehensive ocular examination is necessary because other ocular conditions may exist which can affect the visual development of the patient.

PURPOSE: To evaluate the efficacy, safety, and satisfaction of patients who underwent LASIK for presbyopia correction in myopic patients using aspheric micro-monovision. METHODS: LASIK for presbyopic correction using aspheric micro-monovision was performed in 18 patients between December 2010 and December 2011. Distance, intermediate, and near visual acuity, refractive change, and patient's satisfaction were evaluated for at least 12 months after the surgery. RESULTS: Among dominant eyes, 100% achieved uncorrected distance and intermediate visual acuity of 0.8 or better and 100% of the eyes achieved 0.8 or better binocularly. In the non-dominant eyes, 83% achieved uncorrected near visual acuity of J3 or better, and 94% of the eyes achieved J3 or better binocularly. Postoperatively, the mean manifest refraction spherical equivalent (MRSE) of the dominant eyes were -0.09 +/- 0.35D, -0.17 +/- 0.42D, and -0.17 +/- 0.47D at 1, 6 and 12 months, respectively. The MRSE of the non-dominant eyes were -0.94 +/- 0.53D, -1.03 +/- 0.56D, and -1.02 +/- 0.50D at postoperative 1, 6, and 12 months, respectively, without significant regression. After surgery, the patient's overall satisfaction score was good (4.2 out of 5). CONCLUSIONS: The aspheric micro-monovision protocol showed good distance, intermediate, and near visual outcomes, and was a well-tolerated, stable, and effective procedure for treating patients with myopic presbyopia.

BACKGROUND: It has been known that most of thyroid stimulating antibodies (TSAbs) may interact with epitopes near N-terminal, and thyroid stimulation blocking antibodies (TSBAbs) near C-terminal on the extracellular domain of TSH receptor. However, many authors have reported different results about epitopes reacting with TSH receptor autoantibody (TRAb). TSBAbs inhibit thyroid stimulation of TSH and TSAbs at the receptor level. However, it has been reported that there are some TSBAbs which bind to the other sites, not TSH receptor, or block post-reeeptor process. These findings raise the possibility that TRAbs may be heterogeneous according to the mechanism of action. In order to investigate the heterogeneity of TRAb, we undertook immuno-precipitation using synthetic peptides of TSH receptor and measured TRAb activities by FRTL-5 cells and chimeric CHO cells. METHODS: We studied 102 patients with autoimmune thyroid disease (Graves disease 32, Hashimotos thyroiditis 29, atrophic thyroiditis 41) and 35 healthy persons. Three synthetic peptide fragments of TSH receptor were used to perform immunoprecipitation with serum or IgG of patients and healthy persons, TSAb and TSBAb activities were measured by FRTL-5 cells and CHO cells transfected with wild-type and 2 mutant TSH receptor cDNA (Mc2, Mc1+2). Mc2 and Mcl+2 were rnade to substitute amino acid residues of 90-165, 8-165 of the TSH receptor with corresponding residues of LH/CG receptor, respectively. RESULTS: Two out of 10 IgGs extracted from Graves disease and 2 out of 9 IgGs from atrophic thyroiditis had specific bidings over 0.84% in immunoprecipitation with peptide I (amino acid residue 35-50). Four out of 18 IgGs from Graves disease, 9 out of 41 IgGs from atrophic thyroiditis, and 6 out of 14 IgGs from Hashimotos thyroiditis had specific bidings over 0.84% in immunoprecipitation with peptide II (amino acid residue 317-332). Only 2 out of 10 IgGs from Graves disease had specific bidings over 0.84% in immunoprecipitation with peptide III (amino acid residue 341-358). When 10 IgGs extracted from Graves disease were reacted with wild-type, Mc2, and Mcl+2 CHO cells, 7 IgGs in wild-type and 4 IgGs in Mc2 had positive for TSAb activities. In 10 IgGs from atrophic thyroiditis, 5 in wild-type, 5 in Mc2, and 3 in Mcl+2 CHO cells had positive for TSBAb activities. In Hashimoto's thyroiditis, only 1 with hyperthyroidism had positive for TSAb activity in wild-type and 1 with hypothyroidism had positive for TSBAb activities in both of wild-type and Mc2 CHO cells. Therefore, patients with Graves disease were divided into at least 3 groups according to the TSAb activities measured by wild-type, Mc2, Mcl+ 2 CHO cells and TBII activities. And patients with atrophic thyroiditis were divided into at least 4 groups according to the TBII activities, TSBAb activities by wild-type, Mc2, Mcl+2 CHO cells and FRTL-5 cells. CONCLUSION: From these results, epitopes of TSH receptor reacting with TSAb or TSBAb in autoimmune thyroid disease may be scattered in the TSH receptor, although epitopes of TSAb tend to be near N-terminal and those of TSBAb near C-terminal. Graves disease or atrophic thyroiditis were divided into 3 or 4 groups according to the TBII and TRAb activities. Therefore, TRAb detected in autoimmune thyroid disease may be heterogenous.

PURPOSE: A tumor and mature ovarian cystic teratoma rarely coexist, but since it may affect treatment andprognosis, appropriate pre-surgical diagnosis is important. The purpose of this study was to evaluate thedifference in CT findings between a tumor coexisting with a mature ovarian cystic teratoma and a simple matureovarian cystic teratoma. MATERIALS AND METHODS: CT scans of seven cases of tumor coexisting with mature ovariancystic teratoma were reviewed. In each case, size, margin, nature, septation, solid portion, ascites, invasion,and metastasis were analysed. RESULTS: Coexistent tumors were histopathologically diagnosed as squamous cellcarcinoma in three patients, carcinoid in three, and fibrothecoma in one. In contrast with a simple matureteratoma, a tumor coexisting with a mature cystic teratoma developed in older patients and had a more solidportion, which showed contrast enhancement but did not show calcification or a fat component. Where a tumor andmature cystic teratoma coexisted, ascites and the invasion of adjacent structures were also common. CONCLUSION: If, in an older patient, CT scanning reveals an ovarian cystic tumor with a large solid portion but nocalcification or fat, coexistent tumor should be suspected.
