OBJECTIVE: Increasingly it is being recognized that genetic factors play a significant role in causing malformation. There are many available prenatal diagnostic methods including cytogenetic karyotyping using amniocentesis and cordocentesis, fluorescence in situ hybridization(FISH), and primed in situ labelling(PRINS). Our purpose was to attempt to discuss the clinical use of cytogenetic karyotyping, FISH, and PRINS. METHODS: We conducted 222 cases of cytogenetic karyotyping using amniocentesis and cordocentesis, l0 cases of FISH, and 10 cases of PRINS from January 1996 to July 1998 at Ewha Womans University Mokdong Hospital. Age distribution, chromosomal abnormalities by age group, indication, karyotype, and baby outcomes were performed. RESULTS: Overall incidence of chromosomal abnormalities was 7.7%(17cases) and chromosomal abnormalities were most frequently noted in 30-34 year old women and 35-39 year old women(2.3%, respectively). Among 222 cases, 25-29 year old women were highest(30.2%). Chromosomal abnormalities among cytogenetic karyotyping cases were Down syndrome, Edward syndrome, Patau syndrome, Deletion(8), Inversion(9), etc. The 5 cases of healthy baby among chromosomal abnormalities were delevered. Among 213 cases of karyotyping using amniocentesis, abnormal karyotyping cases were 15 cases. Among 15 cases, 8 cases were terminated and 5 cases of healthy baby were delivered. Among 9 cases of karyotyping using cordocentesis, 2 cases of chromosomal abnormalities(Edward, Down syndrome) were found and 3 cases healthy baby were delivered. Among 10 cases of FISH results, 6 case of FISH results were the same with G-banding and were different from G-banding. Among 10 cases of PRINS results, we got the PRINS results from 7 cases. CONCLUSION: It is concluded that cytogenetic karyotyping, FISH, and PRINS are very useful to detect chromosomal abnormalities.

PURPOSE: The purpose of this study is to compare the growth pattern of breast fed and formula fed infants in the first 1 year of life. METHODS: Anthropometric data (weight, length, head circumference) of at birth, 1, 3, 6, 9 and 12 months were collected by chart review and characteristics of subjects were collected by questionnaires. Among 358 infants, breast fed infants were 161 (84 males, 77 females) and formula fed infants were 90 (42 males, 48 females). Neither group was given solid foods before 4 months. The weight for age, length for age and head circumference for age were calculated. Breast fed infants were separated into 2 groups (breast fed for 4-11 months and breast fed for more than 12 months). RESULTS: Characteristics of infants and mothers were similar in both groups except for maternal age. Mean weight of breast fed group was lower than that of formula fed group at 12 months of age (male: P=0.004, female: P=0.004). However, mean weight of 12 months breast fed group was below formula fed groups weight at 9 and 12 months (P< 0.05). Mean length and head circumference were similar between groups. CONCLUSION: The growth indices of breast fed and formula fed infants are similar at birth, but weight curves of two groups differ in the first 1 year.

PURPOSE: The aim of this study was to evaluate clinical differences by karyotype in Turner Syndrome. METHODS: We evaluated 66 patients with Turner syndrome diagnosed at Yonsei University College of medicine from Mar.1985 to Feb.1993. We divided subproups as pure 45,X groups, mosaisism groups and structural aberration groups. Clinical features, serum estrogen, LH, FSH, concentrations, gonadotropin release after GnRH administrarion and final adult height were compared between groups. RESULTS: 1) The karyotype showed. 45,X : 30 cases(45%), mosaicism : 20cases(30%), (X/Xi(Xq) : 15%, X/XX : 7.5%, X/XY : 3%, XXq- : 1.5%, X/Xr(Y) : 1.5%, X/XXX : 1.5%) structural aberration: 16 cases(24.5%)(X, i(Xq) : 2 0%, XXq- : 3.0%, XXp- : 1.5%) 2) Clinical features were milder in Turner varinats than classical 45,X. Birth weight, body m ass index, thyroid autoantibody titers, carbohydrate intolence, peak GH levels were not significantly different between two groups. 3) Height age delay was more sighificant in 45,X karyotype than in Turner variants. 4) Although 45,X karyotype showed lower Estrogen, higher LH, FSH level than Turner variants, there was no statistically significant difference between two groups. 5) When GnRH was administered to Turner syndrome gonadotropin release were exaggerated. 6) In 25 cases who achieved their final adult height without GH therapy, mean final adult height was 140.9cm and there was no significant difference between 45,X and Turner variants. CONCLUSIONS: In Turner variants, clinical features are milder than classical 45,X and hormone secretion capacity and final adult height is not significantly different between two groups.

An ABO discrepancy was encountered in a 29-year-old woman with a pregnancy of 36 weeks. The patient's red cell was typed as group O and her serum had only anti-A antibody. Absence of B antigen on patient's RBC was confirmed by adsorption-elution test, B substance was not demonstrated in the saliva and serum. B-transferase activity was not detected in the serum. Patient's serum Ig level was within normal range. The patient's father and son had normal O phenotype and no additional abnormalities were detected among the family members studied.

The nm23 gene was originally identified by differential screening of a cDNA library with RNA from low and high metastatic clones of a murine melanoma cell line. And the nm23 gene has been represented as a metastasis suppressor gene. The product of nm23 gene is known to be identical to nucleoside diphosphate(NDP) kinase. The lack of expression of nm23 protein has been correlated with a poorer prognosis in some human tumors, among which are breast carcinoma, malignant melanoma, gastric carcinoma and hepatcelluar cacin-oma. However, in several types of malignant tumors such as colon carcinoma, neuroblastoma and pancreatic carcinoma, unexpected overexpression of nm23 protein was found as compared with normal tissues. Also in a few studies with cervical carcinoma, the expression of nm23 protein was found to be increased as compared with normal cervical tissue recently. Therefore, in this study, we analyzed the expression of nm23-H1 protein by immunohistochemistry method in a series of 40 cervical carcinomas, to determine whether the alterations in the expression of nm23-H1 protein occured in cervical carcinoma as compared with cervical intraepithelial neoplasia(CIN) and normal cervices, and also analyzed the possible association between nm23 protein expression and prognostic parameters of cervical carcinoma at Ewha Womans University Mokdong Hospital from September 1993 to March 1997. The results obtained were as follows; 1. The mean ages of normal control patients, CIN and cervical carcinomas were 42.9 (+/-5.1) years, 39.5(+/-7.7) years, and 49.3(+/-11.7) years respectively. All cases of cervical carcinoma were squamous cell carcinomas. And the number of each stages Ia, Ib, IIa, IIb, III and IV were 13 cases, 8 cases, 6 cases, 9 cases, 2 cases, and 2 cases respectively. 2. In cervical carcinoma, nm23-H1 protein expression was significantly increased as compared with CIN and normal cervical tissue(t=5.017>1.96). 3. In cervical carcinoma, the nm23-H1 protein expression was more increased in higher stages(p=0.021). But it had no significant correlations with primary tumor size, lymphovascular space invasion, parametrial invasion or lymph node metastasis. Our results on nm23-H1 protein expression in cervical carcinoma suggest that cervical carcinoma seems to belong to the group of tumors, like colon carcinoma and neuroblastoma, pancreatic carcinoma in which nm23-H1 overexpression is associated with a more malignant phenotype. In this study, nm23-H1 protein was more expressed in higher clinical stages of cervical carcinoma. Therefore the expression of nm23-H1 protein probably may have a prognostic significance in cervical carcinoma. But a further prospective study on a larger population is needed to establish the role of nm23 gene in this kind of tumor.

OBJECTIVE: To define whether lactase-deficient subjects are intolerable to even a pack of milk(200ml) and whether milk intolerance in the patients with IBD is only due to lactose malabsorption, we performed this study. METHODS: We evaluated 32 healthy adults and 12 patients with active stage of inflammatory bowel disease(IBD) who had not received antibiotics therapy within the previous 3 weeks. Thirty-two healthy adults underwent H2-breath test with 200, 400, 600 and 800ml of milk at 1st, 2nd, 3rd and 4th day of study, respectively. We measured their end-expiratory hydrogen concentrations and asked them to record the gastrointestinal symptoms. Twelve patients with IBD were tested only with 200ml of milk. Lactose malabsorption was defined as the increase of 20ppm over basal H2 concentration and lactose intolerance as having two or more of the following symptoms; abdominal pain, diarrhea, borborygmus and flatus. RESULTS: The prevalence of lactase deficiency was 72%(23 of 32 subjects) at 800ml of milk(lactose 40g). Among the lactase-deficient subjects, lactose intolerance at 200ml of milk(lactose 10g) was noticed only in 13%(3 of 23 subjects). In the patients with active stage of IBD, the frequency of milk intolerance at 200ml of milk was 50%(6 of 12 subjects), which was higher than in the healthy adults(9%). But the prevalence of lactose malabsorber in the patients with IBD at 200ml of milk(17%) was not higher than in the healthy adults(16%). CONCLUSION: Most of lactase-deficient subjects(87%) can ingest one pack of milk without lactose intolerance. The increased prevalence of lactose intolerance in the patients with IBD at 200ml of milk is not originated from lactose malabsorption, but probably from incomplete colonic compensation salvage.

BACKGROUND: Most breast carcinomas are easily categorized as ductal or lobular. However, in some cases the distinction can be difficult since some tumors may have intermediate features of these two. Prior studies suggest that E-cadherin is useful to classify tumors as ductal or lobular, as it is lost in lobular but not in ductal carcinomas. METHODS: We studied the histologic features and E-cadherin expression by immunohistochemistry in 57 cases of breast carcinomas, which were divided into three groups based on histology. Group 1 included 4 cases of infiltrating lobular carcinoma (IFL) and 1 case of lobular carcinoma in situ (LCIS) (n=5). Group 2 included infiltrating ductal carcinoma (IFD) with some features of IFL (n=48). Group 3 included a solid type of intraductal carcinoma (DCIS) (n=4). E-cadherin staining was scored as negative or positive. RESULTS: All 5 cases from group 1 were E-cadherin negative, and all 4 DCIS cases were positive. Only 2 (0.04%) of the 48 cases from group 2 were E-cadherin negative. CONCLUSIONS: Our findings suggest that the majority of cases with morphologically IFD with some IFL features are ductal. E-cadherin immunostaining is of value in helping to characterize breast carcinomas with indeterminate morphologic features.

Traditionally, total parenteral nutrition(TPN) has been used when patients with hypaemesis gravidarum failed to respond to conservative management, but now many physicians attempt to enteral feeding via nasogastric tube because TPN is expensive and has many complications. Recently, we experienced 2 cases of hyperemesis gravidarum successfully managed by enteral feeding via nasogastric tube, therefore we think that this method may be carefully considered to the patients with hyperemesis gravidarum failed to respond to conservative management. So we report them with brief review of the literatures.

Conventional angiography still remains the procedure of choice in evaluation of cerebral aneurysm. However, MRI and MR angiography can play different roles in vizualizing cerebral aneurysm. A 43-year-old male was evaluated for recurrent seizure attacks. The brain MRI showed non-enhancing iso-signal mass on T1WI, signal voiding mass with stalk-like structure on coronal T2WI in the right temporal region. MRA also revealed dark round signal. However, the conventional cerebral angiography failed to visualize it. Finally, the mass was confirmed as a huge aneurysm filled with intraluminal thrombus on operation. It should seem that contrast media could not fill the aneurysmal sac because of intraluminal thrombus in conventional angiography. But aneurysmal sac seemed to be visible on MRA as paramagnetic artifact of thrombus. So, it can be assumed that MRA is superior to the conventional angiography in some cases of cerebral aneurysm, especially when it is associated with intraluminal thrombus.
