The isolation of fetal cells from maternal circulation has the potential to allow relativelyself prenatal diagosis for all pregnant women. The present technology, however, has notreached the accuracy required for clinical diagnosis because of maternal cell contaminationSo we published a new method for enrichment of nRBC in a fetal cell isolation(1996).In this study, attempted to FISH analysis of nRBC which was isolated by our ownmethods. We evaluated the efficiency of FISH.As the results, we have successfully used FISH on enriched nRBC.We were able to identified 2 abnormal fetus which were confirmed by conventionalcytogenentic study as Down syndrome(Fig.1) and Klinefeltre syndrome(Fig.2). And thesensitivity and specificity for FISH was 86%(49/57) and 92.3%(36/39), respectively.According to our results, fetal cell analysis by FISH can be reliable used for prenatalaneuploidy diagnosis. However, the problems of enrichment of the fetal cell and FISH probeor condition should be over come before analyze.

BACKGROUND/AIMS: The increase of colonoscopy procedures has led to an increase in the diagnosis of carcinoid tumors in the lower gastrointestinal tract. The purpose of this study was to identify the clinical and pathological characteristics that affect the treatment and recurrence of carcinoid tumors of the lower gastrointestinal tract. METHODS: A 10-year (1999-2009) retrospective analysis of 41 patients with carcinoid tumors of the lower gastrointestinal tract at the Chungbuk National University Hospital was conducted. Patient and tumor characteristics, treatment and recurrence were analyzed. RESULTS: The mean age was 47.4+/-12.4 (range, 22-79 years) and the male to female ratio was 1:0.64. The mean tumor size was 9.4+/-4.8 (3-20) mm. In the lower gastrointestinal tract, the rectum was the most frequent location of the lower gastrointestinal carcinoid tumors (92.7%). Twenty-nine out of 41 patients were treated by endoscopy (mean size of tumor: 8.0+/-3.4 mm) and 12 were treated by surgery (mean size of tumor: 13.8+/-5.8 mm)(P=0.011). Among the patients treated by endoscopy, only one patient had a complete resection. However, the histology showed that 10 patients treated by endoscopy had positive resection margins; all 10 cases (35.7%) had a polypectomy (P=0.013). The mean follow-up duration was 19.2+/-14.5 months, and there were two recurrences of rectal carcinoid tumors. CONCLUSIONS: Both endoscopic and surgical resections were effective methods for the treatment of lower gastrointestinal carcinoid tumors. However, endoscopic polypectomy should be carefully considered because of the possibility of more frequent incomplete histological resections. Moreover, even for small rectal carcinoid tumors, follow-up examination should be performed to evaluate for tumor recurrence.

PURPOSE: We retrospectively investigated to find out the equation of calculating the probability of minimal change nephrotic syndrome (MCNS) using clinical parameters. We prospectively investigated to determine the usefulness of the mathematical model. METHODS: We retrospectively examined 56 patients with nephrotic syndrome (NS) (30 MCNS and 26 non-MCNS) diagnosed by kidney biopsy. A mathematical model for calculating the probability of MCNS was obtained through multiple logistic analysis in SAS statistics package. In addition, we prospectively studied 28 patients with NS. Clinical MCNS and non-MCNS were classified according to the probability of 85% in the mathematical model. Kidney biopsy was performed, and serum albumin and urinalysis were measured after 2 weeks of steroid treatment. RESULTS: In the retrospective study, the mathematical model was P=ea/(1+ea), a=17.2507 - 5.5777xON - 4.2256xALB-0.000579x24PROT - 1.2569xUBL+2.1703xUAL. The mode of onset (ON), 24 hours urine protein (24PROT), serum albumin concentration (ALB), the grade of hematuria (UBL) and proteinuria (UAL) were included as clinical parameters. At the probability of 85%, the sensitivity and specificity for predicting MCNS was 73.3% and 100% respectively. In the prospective study, the result of kidney biopsy was consistent with clinical MCNS and non-MCNS according to a mathematical model. All clinical MCNS showed negative proteinuria on urinalysis and a significant increase in serum albumin after 2 weeks treatment (1.85+/-0.30 g/dL to 2.88+/-0.26 g/dL, p<0.05). CONCLUSION: We conclude that the mathematical model for predicting the probability of MCNS may be useful in diagnosis of the MCNS.

Terlipressin has splanchnic vasoconstrictive effects, and is generally used for the management of gastroesophageal variceal bleeding secondary to liver cirrhosis. Terlipressin is a synthetic arginine vasopressin (AVP) analog containing a nonapeptide sequence. Terlipressin has increased selectivity for the V1 receptor, compared with AVP; hence, it is considered to be a safe vasoconstrictor. However, side effects such as hyponatremia and seizure, although very rare, have been reported. Hyponatremia related to terlipressin may be caused by the syndrome of inappropriate antidiuresis (SIAD), which is a disorder of sodium and water balance characterized by hypotonic hyponatremia without elevation of the antidiuretic hormone level. Here, we report a case of hyponatremic seizure induced by an infusion of terlipressin in a 52-year-old female who had isolated gastric variceal bleeding secondary to alcoholic liver cirrhosis.

BACKGROUND: Recently, G1 cells, characterized by distinctive doughnut-like shape with blebs have been reported as a reliable marker for glomerular hematuria. We investigated the validity of the urinary G1 cells in distingushing glomerular from non-glomerular hematuria. In addition, we evaluate the influence of urine osmolality, pH and proteinuria on dysmorphic erythrocytes and G1 cells. METHODS: One hundred and twenty patients with hematuria including 60 glomerular (GH) and 60 non- glomerular hematuria (NGH) were examined. The percentage of urinary dysmorphic erythrocytes and G1 cells using phase-contrast microscopy was determined. Urine osmolality, pH, and spot urine protein/ creatinine ratio were examined. RESULTS: The proportion of G1 cells differed significantly between the two group (7.8+/-16.0% in GH vs. 0% in NGH, p<0.05). At the cut-off value of 50 % dysmorphic erythrocytes, the sensitivity and specificity for the detection of GH was 88.3% and 93.3%, respectively. At the cut-off value of 1% G1 cells, sensitivity and specificity were 60.0% and 100%, respectively. When both of 50% dysmorphic erythrocytes and 1% G1 cells were considered as the cut-off value, the sensitivity and specificity were 91.0% and 100%, respectively. There was a significant difference in the percentage of dysmorphic erythrocytes and G1 cells at different urine pH. There was a significant correlation between urine osmolality and dysmorphic erythrocytes (r=0.41, p< 0.05), but not for G1 cells. No significant correlations were observed between G1 cells and proteinuria or pH. CONCLUSION: Evaluation of both urinary G1 cell and dysmorphic erythrocytes at the same time could improve the diagnostic value for differentiating glomerular hematuria.

Primary epiploic appendagitis (PEA) occurs due to inflammation of an epiploic appendage, which is a peritoneal pouch that arises from the serosal surface of the colon. PEA is often associated with infarction caused by torsion or spontaneous venous thrombosis. PEA is a self-limited disease with a course of approximately 10 days, and it requires only symptomatic management for pain. But it clinically manifests with localized abdominal pain that is often mistaken for appendicitis, diverticulitis, or cholangitis. Therefore, PEA had been diagnosed at surgery for the past few decades. Making the preoperative diagnosis of PEA through ultrasound and computed tomography (CT) has recently become possible. We report here on four cases of PEA that were diagnosed and treated by symptomatic management.

Objectives ; This study was conducted to reveal the health effects of aircraft noise on the residents live near the military airport. METHODS: We sampled systematically 87 residents as the high exposed group, 58 residents as the low exposed group according to the geographical distance from the airport. We also sampled 67 residents as the control group lived far from the airport. Noise levels were measured for conform the exposures. Self-administered questionnaires for symptoms, air conduction hearing threshold level, blood pressure blood cholesterol with health examinations, and SCL-90-R were introduced to get the data from the residents. RESULTS: The Ld/n at the area near the airport was 72.4 dB, however that of control area was 67. 7 dB. The value of pure tone average, high pure tone average, and threshold of 4,000 Hz were decreased with exposure level significantly. Linear regression analysis showed that the noise exposure level of the airport was related to the hearing threshold at pure tone average, threshold of 4,000 Hz, and high pure tone average. The systemic and diastolic blood pressure showed dose-response relationship with noise exposure. The prevalence of hypertension was higher in exposed group, but not statistically significant. In linear regression, noise level was related to systolic and diastolic blood pressure with other variables such as age, sex, BMI (Body Mass Index), and family history of hypertension. SCL-90-R showed that exposed group had higher score significantly in neurotic and psychologic variable and felt the various somatic symptoms. CONCLUSIONS: These results suggest that aircraft noise would influence hearing loss at low frequencies as well as 4,000 Hz and higher frequencies, systolic and diastolic blood pressure, and psychological response.

Appendiceal intussusception is a rare disease with variable clinical findings, ranging from acute appendicitis to chronic recurrent abdominal pain or rectal bleeding. Occasionally, it is incidentally discovered with no symptoms. Because a preoperative diagnosis is difficult, it can be diagnosed either after surgery, in the case of acute appendicitis, or after a polypectomy, based on being mistaken for a polyp. During a colonoscopy, an appendiceal intussusception should be suspected if the appendiceal orifice is not observed at the cecum and there is a polypoid lesion at the location where the appendiceal orifice is expected. Treatments are usually determined according to preceding diseases. It is important that the colonoscopist avoid careless endoscopic removal by mistaking the intussusception for a polyp.
