BACKGROUND: High plasma levels of coagulation factor VII (FVII) are associated with a risk of coronary artery disease (CAD). Plasma FVII levels are influenced by environmental and genetic factors. We investigated whether the risk of CAD is associated with R353Q polymorphism and whether this polymorphism is associated with factor VII activity METHODS: We analysed plasma levels of FVII:C and FVII genotype for R353Q polymorphism in 85 CAD patients, 63 healthy controls, and 27 patient controls. And total cholesterol, HDL-cholesterol and triglyceride were measured in the same study populations. RESULTS: There was no difference among CAD patients, healthy controls, and patient controls in plasma levels of FVII:C. Allele Q of the R353Q polymorphism was less frequent in CAD patients (11.8%) than healthy controls (17.5%), although the difference was not statistically significant. Patients with the RQ genotype had a decreased risk of CAD (odds ratio, 0.29). There was no association between R353Q polymorphism and plasma levels of FVII:C. Plasma levels of FVII:C were positively correlated with total cholesterol and triglyceride. CONCLUSIONS: Our findings suggest that R353Q polymorphism may confer significant protection from CAD and that plasma levels of FVII:C may influenced by total cholesterol and triglyceride.

The new onset of acanthosis nigricans in an adult-especially when the lesions appear on mucosal membranes such as the lips, periocular areas, and anus-may be indicative of an underlying tumor. Adenocarcinoma of the gastrointestinal tract is the most common malignancy-most often cancer of the stomach. A 72 years old female had disseminated, symmetrically distributed, brownish black pigmentation and papillary hypertrophy on the intertriginous and flexural areas for 12 months, and gastric adenocarcinoma was confirmed during the evaluation of internal malignancy. The cutaneous finding of acanthosis nigricans was a significant cutaneous marker of internal malignancy in this case.

PURPOSE: Transplant patients under immunosuppression are susceptible to mycobacterium tuberculosis infection. We analyzed renal transplant recipients, to evaluate the risk factors, clinical characteristics, and long-term outcomes of post- transplant tuberculosis (TB). METHODS: This study is based on the records of renal allograft recipients from October 1991 to June 2006 in two transplant centers in Korea. The demographic data, clinical manifestations, and long-term outcomes of this cohort of patients were retrospectively analyzed. RESULTS: Total 617 patients were enrolled in this study. Eighteen cases of TB (2.92%) occurred with a mean interval from transplant to diagnosis of TB of 33.1 (range: 1~121) months. Most of post-transplant TB were pulmonary TB (including pleural) (13/18), and extrapulmonary TB occurred in 5/18. There was no difference in the prevalence of diabetes mellitus, hepatitis B or C, and immunosuppressive agents between the patients who had developed post- transplant TB and who had not. However, there was higher incidence of acute rejection in post-transplant TB group (0.9+/-1.1 vs. 0.4+/-0.6, P=0.043), and post-transplant TB group had a tendency toward more past history of TB infection (P=0.096). Thirteen patients were successfully treated, 2 patients have been under treatment and 3 patients died. The patient survival was significantly reduced by post- transplant TB in multivariate analysis (relative risk=3.355, P=0.038). CONCLUSION: Post-transplant TB is a serious problem, which is associated with poor outcomes in renal transplant patients. Therefore, high index of suspicion is warranted to ensure early diagnosis and prompt initiation of treatment.

PURPOSE: The purpose of this study was to identify the factors that influence the functional status of patients with heart failure. METHOD: A descriptive, correlational study design was used. The participants in this study were 260 patients with heart failure who were admitted at Y University and U University in Seoul, Korea. Between September 2005 and December 2005 data was collected by an interview using a questionnaire and from medical records. The Functional status was measured with KASI. Physical factors (dyspnea, ankle edema, chest pain, fatigue, and sleep dysfunction), psychological factors (anxiety and depression), and situational factors (self-management compliance and family support) were examined. RESULT: In general, the functional status, anxiety, depression, self-management compliance, and family support was relatively not good. The level of fatigue was highest and the level of ankle edema was lowest for physical symptom experiences. In regression analysis, functional status was significantly influenced by dyspnea(23%), age(13%), monthly income(7%), fatigue(3%), ankle edema(2%), depression(1%), and length of stay in the hospital(1%). These factors explained 50% of the variables in the functional status. CONCLUSION: These results suggest that psycho-physiological symptoms management should be a focus to improve the functional status in patients with heart failure.

The major aneuploidies diagnosed prenatally involve the autosomes 13, 18, 21, and sex chromosomes X and Y. Fluorescence in situ hybridization (FISH) allows rapid analysis of chromosome copy number in interphase cells. We retrospectively reviewed 130 amniotic fluid interphase FISH analyses from January 1997 to December 2001. The review was done in order to assess the role of interphase FISH among the patients who were at the risk of fetal aneuploidies. The sample was considered to be aneuploid when 70% of or more than the total number of hybridized nuclei displayed the same abnormal hybridization pattern for a specific probe. All of 130 cases but one met the criteria. The results were considered as informative and they were obtained in 24-48 hr. The overall detection rate for aneuploidies was 100% (2 cases of trisomy 21, 2 cases of trisomy 18, and 1 case of Turner syndrome). In comparison to cytogenetics, the rates of both sensitivity and specificity were 100%. The experiment demonstrates that FISH can provide a rapid and accurate clinical method for prenatal identification of chromosome aneuploidies. The experiment can also serve as an adjunctive test to help cytogenetics to reduce significant amount of emotional stress of patients and physicians through early decision making process.

Primary mediastinal nonseminomatous germ cell tumor is extremely rare. Apart from rarity and large size, mediastinal germ cell tumors show striking similarity to testicular tumors in age, incidence, and tumor type. The symptoms associated with these tumors are related mainly to size, invasion of neighboring structures, and distant metastases. Tissue diagnosis is obtained by biopsy of the primary lesion or by biopsy of metastatic sites. Tumors often present with advanced bulky disease, which are unresectable. So these tumors require an aggressive multidisciplinary approach to management. Optimal management includes aggressive surgical debulking and early use of cisplatin-bleomycin-based combination chemotherapy. Serial biomarker measurements permit early recognition of recurrence and improved timing of surgical intervention. The prognosis for mediastinal germ cell tumors is poor, not only because they are far advanced at the time of diagnosis but also because some of the tumors-such as embryonal carcinomas, choriocarcinomas, and endodermal sinus tumors-are very aggressive. In these cases, we present three young male patients with large mass on anterior mediastinum. Tissue diagnosis was obtained by primary lesion biopsy. All patients received surgical debulking and combination chemotherapy and experienced a brief response and eventually had relapses. We report these cases with a review of literatures.

OBJECTIVE: To evaluate planned pregnancy rate and associated factors related planned pregnancy. METHODS: We surveyed 1,396 cases from May 2002 to December 2002. The cases were derived from the Maternity school. They filled out questionnaire including planned pregnancy, medico-social-economic status. Then, we assessed the planned pregnancy rate with associated medico-social-economic state, through the prospective study. RESULTS: The planned pregnancy rate is 51.4%. The major factor which affected the planned pregnancy rate is the income of the family. The association with the planned pregnancy rate and the parity, age, and educational attainment of the women are not statistically significant. In unplanned group, exposure to alcohol, X-ray and medication is significantly increased in early pregnancy. CONCLUSION: The planned pregnancy can prevent induced abortion and reduce the birth defects due to early exposure to teratogen. Therefore it is important to make an effort to raise the planned pregnancy rate.

BACKGROUND: Obstructive airway disease patients with increased variability of airflow and incompletely reversible airflow obstruction are often categorized as having asthma–chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS). ACOS is heterogeneous with two sub-phenotypes: asthma-ACOS and COPD-ACOS. The objective of this study was to determine the difference in risk of exacerbation between the two sub-phenotypes of ACOS. METHODS: A total of 223 patients exhibiting incompletely reversible airflow obstruction with increased variability (spirometrically defined ACOS) were enrolled. These patients were divided into asthma-ACOS and COPD-ACOS according to their physician's diagnosis and smoking history of 10 pack-years. Within-group comparisons were made for asthma-ACOS versus COPD-ACOS and light smokers versus heavy smokers. RESULTS: Compared to patients with COPD-ACOS, patients with asthma-ACOS experienced exacerbation more often despite their younger age, history of light smoking, and better lung function. While the light-smoking group showed better lung function, they made unscheduled outpatient clinic visits more frequently. On multivariate analysis, asthma-ACOS and poor inhaler compliance were significantly associated with more than two unscheduled clinic visits during the previous year. CONCLUSION: Spirometrically defined ACOS includes heterogeneous subgroups with different clinical features. Phenotyping of ACOS by physician's diagnosis could be significant in predicting future risk of exacerbation.

The aim of this study was to establish a multi-center birth defects monitoring system to evaluate the prevalence and the serial occurrence of birth defects in Korea. Ten medical centers participated in this program. A trained nurse collected relevant records from delivery units and pediatric clinics in participating hospitals on a monthly basis. We observed 1,537 cases of birth defects among 86,622 deliveries, which included live births and stillbirths. The prevalence of birth defects was 1.8%, and the sex distribution of the birth defect cases was 55.2% male and 41.6% female. The highest proportion of birth defects was in the cardiovascular system (17.5%), followed by birth defects involving in the genitourinary system (15.6%). Chromosomal anomalies were detected 30.0 per 10,000 births. Of these chromosomal anomalies, Down syndrome was most frequently observed. This study led to an establishment of a multi-center active monitoring system for birth defects. To better understand the serial occurrence of birth defects in Korea, it is necessary to increase the number of participating hospitals and to launch on a nation-wide multi-center study.
