OBJECTIVES: The objective of this study is to analyze 1,068 cases of prenatal genetic amniocentesis and to compare the results with reported studies. METHOD: We analyzed 1,068 cases of midtrimester prenatal genetic amniocenteses from September 1994 to February 1999, and investigated the fetal chromosomal abnormality, obstetric outcomes and complications by the indications of genetic amniocentesis and prophylactic antibiotic use at the Department of Obstetrics and Gynecology, Ajou University School of Medicine. RESULTS: Abnormal maternal serum markers were the most common indication of amniocentesis (57.7%) and the most common age distribution was 25-29 years (39.2%). One case of early amniocentesis (14 gestational weeks) was performed. The overall incidence of chromosomal aberration was 5.2% (56/1,068), of which there were 28 cases (50.0%; 28/56) of numerical aberrations and 28 cases (50.0%; 28/56) of structural aberrations. There were 50 cases (4.7%) of autosomal chromosomal aberrations and 6 cases (0.6%) of sex chromosomal aberrations. The pregnancy outcome was full-term delivery in 86.5%, preterm delivery in 7.6%, termination of pregnancy in 4.0%. There were no cases of serious complications including fetal death except for a case of self-limited amniotic fluid leakage(high leakage) in which the pregnancy was maintained. There were no significant differences between prophylactic antibiotics user group and non-user group in obstetric complications and outcomes. CONCLUSION: We could confirm that the trend in the indication of genetic amniocentesis had changed from advanced maternal age(35 year-old) toward abnormal maternal serum marker(triple test), and we recognized the importance of genetic amniocentesis according to the various antenatal screening tests of maternal serum marker, antenatal ultrasound, past history of fetal anomaly or family history of fetal chromosomal anomaly in the younger age groups(< 35 year-old) that are involved in more than half of the chromosomal anomaly. Further study will be needed to elucidate the efficacy of using prophylactic antibiotics in amniocentesis.

OBJECTIVE: It is known that mouse embryos before implantation develop in a low oxygen environment of 3- 8% concentration and with antioxidant materials such as vitamins, antioxidant enzymes, ferrous binding proteins, and albumin in follicular and tubal fluids. However, the 20% oxygen culture condition with chemically defined media might be produce an abundance of ROS, and leads to developmental delay or developmental block in vitro. In this study, we attempt to elucidate the relationship between intracellular H2O2 production and embryo development in different oxygen culture conditions of mouse embryos. METHODS: Prenuclear embryos from C57BL/CBA Fl hybrid and ICR mouse were cultured in incubators which provided 5% carbon dioxide, 20% oxygen and 5% carbon dioxide, 5% oxygen. Measurement of H2O2 level in a embryo was performed with DCHFDA(2, 7 -dichlorodihydroflourescein diacetate)and analyzed with Quanti-cell 700, and the number of blastomeres was counted with DAPI( 4, 6'-diamidino-2-phenylindole). RESULTS: Oxygen concentration of the culture medias was significantly higher in the 20% oxygen environment compared to that of 5% oxygen environment. Culture of mice embryos in high oxygen condition leads to high HO concentrations at 2 cell stage and developmental delay or ""2-cell block"" regardless of the strain. But in a 5% oxygen environment, which is similar to in-vivo conditions HO production was suppressed continuously through out culture and development of embryos was definitely improved. CONCLUSION: These results suggest that there is a difference in the production of ROS or protective mechanism according to the mouse strains and stage of development, and it is thought that in-vitro culture in 5% oxygen environment provides stable in vivo equilibrium but in a 20% oxygen environment there is production of ROS which overcome the protective mechanism which leads to cellular damage and embryo developmental delay.

PURPOSE: To investigate the effects of 0.15% brimonidine tartrate ophthalmic solution spray on the luminal changes in the nasolacrimal excretory system. METHODS: A prospective study was performed on 52 eyes in 26 patients complaining of epiphora in both eyes. The randomly-assigned 26 test eyes (cases) received spray of the solution through the nasal cavity, and the other 26 eyes (controls) were irrigated with the same drug through the inferior calnaliculus. Dacryocystography was then performed to observe the luminal changes jn the nasolacrimal excretory system, patient symptoms and physiologic drainage functions. RESULTS: The changes in lumen width of the nasolacrimal duct (NLD) were noted, and the changes in lumen width of the lacrimal sac were not significant in either mode. The upper and middle parts of the NLD were widened more in the irrigation group, and the lower part of the NLD was widened more in the spray group. Though there was no significant difference in the physiologic drainage functions, the patients in both groups reported reduced symptoms. CONCLUSIONS: Brimonidine tartrate spray altered the width of the NLD and improved the subjective symptoms of patients. Therefore, the spray can be applied in functional NLD obstruction patients before the surgical procedure.

Pseudocyst of the auricle presents as a non-inflammatory, fluctuant swelling on the upper half or third section of the ear, due to intracartilaginous accumulation of fluid. Histological examination shows an intracartilaginous cavity without an epithelial lining. The etilogy and pathogenesis of this disorder remains unknown, but the lesion is likely to be due to localized de-generation of cartilage. The degenerated cartilage is replaced by a vascular fibrous tissue from which there is serious exudation, and a clinical cystic swelling is formed. We describe in this report three cases of pseudocyst of the auricle, of which one was treated successfully by surgical excision and a pressure dressing, and the others by aspiration and steroid injection therapy. In all cases, the skin lesions had not recurred, and the patients were left with an excellent cosmetic result.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

Twin pregnancy is at increased risk for congenital anomalies. Although twins were relatively infrequent, they accaunted for a disproportionately large portion of adverse pregnancy outcome, primarily as a consequence of preterm delivery, gestational diabetes, and pregnancy induced hypertension. In case of twin pregnancy with a single anomalous fetus, the clinicians are faced with difficult decision-making processes regarding the route of delivery, when to deliver, how aggressively to attempt to prevent delivery. Twin pregnancy discordant for a fetal abnormality can be managed expectantly or by selective fetocide of abnormal twin. Recently we experienced two cases of twin pregnancy with a single anornalous fetus. We reported cases with concerned literatures.
