    Among 2,055 cases of abnormal findings detected by prenatal ultrasonography at Yonsei University College of Medicine from January 1996 to June 2002, the incidence and the site of cystic hygroma were evaluated. The clinical courses and postnatal prognosis were studied in four cases with cystic hygroma developed in unusual sites. Among 2,055 cases of abnormal ultrasonographic findings, 76 cases (3.70๏ผ…) were diagnosed as cystic hygroma. Among 76 cases of cystic hygroma, 4 cases (5.3๏ผ…) were detected in unusual sites; 1 case in mediastinum, 1 right axillary area, and 2 in anterolateral portion of neck. In cystic hygroma, prenatal accurate ultrasonographic findings including size and site of mass are important. Cystic hygroma developed in unusual sites are associated with perinatal complications including airway obstruction and compression of the surrounding organs. In giant cystic hygroma, cesarean section should be considered to avoid trauma and birth injury. After delivery, close observation and proper management are required.ope

    Objective : Ultrasonography is screening modality of choice and plays an important role in prenatal diagnosis of various diseases and neoplasm of fetus. Recently, Magnetic Resonance Imaging was used as a diagnosis tool to fetal disease. We would like to evaluate efficacy of ultrasonography and magnetic resonance imaging for the diagnosis of fetal abdominal solid tumor. Methods : Among 2,055 cases of abnormal ultrasonography findings detected by prenatal ultrasonography from January 1996 and June 2002, a comparison between the diagnosis made by prenatal ultrasonography, fetal magnetic resonance imaging (MRI), postnatal radiological studies and histopathologic studies was made in four cases with fetal abdominal solid tumor. Results : The first case was diagnosed as adrenal tumor or hepatic tumor by US, hemangioedothelioma of liver by fetal MRI, and confirmed as hemangioedothelioma postnatally. The second case showed concordance with mesoblastic nephroma among the diagnosis made by US, fetal MRI, and postnatal histopathologic studies. The third case was diagnosed as extrathoracic pulmonary sequestration by US and MRI, and the same diagnosis was made by postnatal histopathologic studies. The fourth case was suspected as kidney tumor by US and was diagnosed as adrenal as adrenal neuroblastoma postoperatively. Conclusion : Fetal solid tumor is not a common disorder, but the location, size and orgin of tumor plays important role in the prognosis of neonatal period; additional workup by fetal MRI would improve the diagnosis of such tumors.ope

[์˜๋ฌธ] Objective : This study was designed for determination of the additional effect of alendronate to ongoing hormone replacement therapy in postmenopausal women. Methods : Alendronate (10mg/day, orally) was added in 66 postmenopausal women with estrogen replacement therapy who were taken HRT more than 2 years previously. The patients were followed up for 1 year thereafter. We measured bone mineral density and bone turnover markers(osteocalcin, ALP, Dpd/Cr) at that time prior to HRT, 1 year, 2 year after HRT and 1 year after combination of alendronate therapy. Results : The BMD(g/cm2) of L2-4 were 0.77ยฑ0.08(t-score -2.86ยฑ0.69) prior to HRT, 0.82ยฑ0.07(t-score -2.53ยฑ0.49) 1yr after HRT, 0.80ยฑ0.11(t-score -2.61ยฑ0.92) 2yr after HRT, and 0.88ยฑ0.08(t-score -2.05ยฑ0.70) after combination therapy. Serum osteocalcin(ng/ml) level were 30.3ยฑ14.8, 21.09ยฑ14.09, 17.31ยฑ8.46, and 10.85ยฑ9.09 respectively. Dpd/Cr(nmole/mmole) were 7.0ยฑ4.5, 5.82ยฑ0.91, 5.29ยฑ2.15, and 4.22ยฑ0.61. From these results, we can observe more significant increase of BMD and decrease of bone turnover rate following combined therapy rather than HRT only. Conclusion : This study shows that the addition of alendronate is beneficial in postmenopausal women with ongoing estrogen replacement therapy by preventing or treatment of osteoporosis.ope

[์˜๋ฌธ]Endometriosis, a common gynecologic disorder responsible for severe dysmenorrhea, chronic pelvic pain, dyspareunia and infertility, is defined as the presence of endometrial gland and stroma outside the uterus.Although endometriosis is a pathologically benign disease, the endometrial tissue has the ability to attach and invade to other tissue like a carcinoma.Despite of extensive studies, its etiology and pathogenesis are not fully understood. There is an increasing evidence showing endometriosis is a pollygenically inherited disease of complex multi-factoreal etiology, and recent studies have suggested that abnormalities in the regulation of specific genes are involved in the development of endometriosis.In the past, the investigation of gene expression was limited by the inability to study more than one gene at a time. The introduction of DNA microarray technology has made it possible to examine the expression of thousands of genes at a time. Using a cDNA microarray consisting of 23,920 genes, we analyzed gene expression profiles of ovarian endometrial cysts from 4 patients. By comparing expression patterns in endometrial tissue and normal ovarian tissue of the study group and normal ovarian tissue of control group. Validation of results of several up- and down-regulated genes was performed by reverse transcription-polymerase chain reaction(RT- PCR)We identified 401 genes that were up-regulated by a twofold in the endometrial cyst. 62 of 401 genes were up-regulated by a threefold.98 genes were down-regulated by two fold in the endometrial cyst. 39 of 93 genes were down-regulated by a threefold.Endometrial cysts and normal ovarian tissue in the study group 13 genes were up-regulated and 4 genes were down-regulated.Our data showed that expression of those genes regulated cell structure, cell cycle and adhesionas(ex. COL8A1, CALD1, ACTG2, PCOLCE, COL16A1, SPON2) were observed up-regulated in endometrial cyst of the study group.Genes related to protein metabolism and modification(ex. MMP11, AEBP1, ECEL1, TPSB1, MMP2) were also up-regulated.Genes related to steroid and lipid metabolism (ex. CYP11A1, HSD3B2, APOC1, TM7SF2, SCD, HMGCR, CYP51A1) and genes related to immunity and cell protection (ex. GSTA1, GSTA3, GSTA5) were down-regulated.There were significant difference in gene expression for PLAU, MOXD1, PACAP, C4A, FAP, C4B, CSPG2, IGJ, MMP11, LOC374572, COMP between endometrial cysts and normal ovarian tissue in patients, but not so between normal tissue in patients and control group. RT-PCR revealed different expression in MOXD1 and CSPG2. Our study indicated that ectopic imolantation and growth of endometrial cells may be explained by up-regulated of those specific genes that are involved in cell cycle, protein cell structure, cell adhesion and differentiation in advanced endometriosis.ope
