PURPOSE: Congenital anomalies are known as a major cause of neonatal death with prematurity and birth injuries. We surveyed the incidence of congenital anomalies among livebirths and stillbirths delivered at our hospital, and detected in neonatal and postneonatal period. METHODS: The statistical study was done about congenital anomalies among 9,569 deliveries (9,438 livebirths and 131 stillbirths) at Ulsan University Hospital during the periods of 5 years from Jan 1992 to Dec 1996. We reviewed delivery and newborn record, OPD chart, admission chart retrospectively. We investigated the incidence of congenital anomaly according to each year, period, outcome of delivery, sex, birth weight, gestational age, maternal age, Apgar score, multiple pregnancy, and each system. RESULTS: 1) The overall incidence of congenital anomalies was 5.0% (481 cases) among 9,569 deliveries. The annual incidence was 4.5% in 1992, 5.1% in 1993, 5.2% in 1994, 5.8% in 1995, 4.7% in 1996. 2) The incidence of congenital anomalies detected in neonatal period was 3.5% (333 cases) and 1.5% (148 cases) in postneonatal periods. 3) The incidence of congenital anomalies was 4.9% among live births and 9.2% among stillbirths. 4) The incidence of congenital anomalies was 5.3% in male and 4.7% in female. 5) The incidence of congenital anomalies among the babies, below 2,500g of birth weight was 7.7%, between 2,500g and 3,999g was 4.7%, and over 4,000g was 6.8N. 6) The incidence of congenital anomalies among the babies, below 32 weeks of gestational age was 12.9%, between 32 weeks and 36 weeks was 7.4%, between 37 weeks and 41 weeks was 4.7%, and over 42 weeks was 5.1%. 7) The babies born to mothers younger than 20 years of age have anomalies in 7.1%, mother between 20 years of age and 35 years of age in 5.0%, and older than 35 years of age in 6.5%. 8) The incidence of congenital anomalies according to Apgar score among live births between 0 and 3 was 9.8%, between 4 and 6 was 6.0%, and between 7 and 10 was 5.0%. 9) The incidence of congenital anomalies according to multiple pregnancy was 8.6%. 10)The systems of congenital anomalies in order of incidence were as follows; The digestive system (25.6%), the cardiovascular system (22.1%), the genitourinary system (18.9%), the musculoskeletal system (15.5%), the skin and soft tissue (11.7%), the central nervous system (1.6%), the respiratory system (l%), the others (3.6%). CONCLUSIONS: Regular examination and screening on congenital anomaly is required from newborn period to infant and childhood. In view of these considerations, the incidence of congenital anomaly may be increased more than the past reports because of development of recent diagnostic techniques.

BACKGROUND: Noninvasive measurements that relate to the extent and severity of coronary atherosclerosis have long been sought for clinical screening of patients with chest pain syndromes and for use in clinical trials. Intima-media thickeness (IMT) of the carotid artery has been suggested to be associated with coronary artery atherosclerosis. In this study, we tried to assess the relation of carotid artery atherosclerosis by B-mode ultrasonography with presence and severity of coronary artery disease. METHOD: We studied 57 patients (36 men, 21 women) with ischemic heart disease, mean age 65+/-8 yrs (48 to 83 yrs), who underwent both coronary angiography and carotid ultrasonography with 10 MHz transducer. The patients who had received revascularization procedure were excluded. We classified the patients into two groups, the control group without significant coronary stenosis (18 patients) and the coronary artery disease (CAD) group (39 patients) with significant luminal stenosis (> or =50%). The CAD group was divided into single vessel disease group (SVD, 19 patients) and multivessel disease group (MVD, 20 patients). IMT was measured in far wall of common carotid artery (CCA) at 10 mm proximal to carotid bulb and abnormal IMT was defined if the measurement was greater than mean IMT+2SD of control group. Serum total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), Lipoproteinp (a)(Lp(a)) were measured and history of hypertension, diabetes mellitus, and smoking were investigated. RESULTS: A significant difference in IMT of the CCA was found between control and CAD group (0.76+/-0.09 mm vs. 0.97+/-0.20 mm; p<0.0001). Also a significant difference in the number of atherosclerotic plaque was found between the two groups (control; 0.67+/-1.14 vs. CAD; 1.87+/-1.75; p<0.005). In the CAD group, both mean IMT and numbers of athero-sclerotic plaque tended to increase in MVD group compared with SVD group (1.03 mm vs. 0.91 mm; p=NS, 2.65 vs. 1.05; p<0.05). The sensitivity of IMT for prediction of significant CAD was 66.7%, the specificity 83.3%, the positive predictive value 89.7%, and the negative predictive value 53.6%. The sensitivity of plaque presence on the carotid artery for prediction of CAD was 71.8%, the specificity 61.3%, the positive predictive value 80.3% and the negative predictive value 50.5%. Among risk factor, diabetes mellitus and Lp (a) were correlated well with IMT of CCA, Hypertension was correlated with atherosclerotic plaque. History of smoking was correlated with coronary artery disease. CONCLUSION: Increases in IMT and plaque of the carotid artery, as measured noninvasively by ultrasonography, can be used as a predictor of significant coronary artery stenosis.

Vascular complications such as hematoma, pseudoaneurysm and arteriovenous fistula that occur after intracoronary or intracardiac procedures are responsible for considerable morbidity and some mortality. Iatrogenic aneurysms are usually postcatheterization pseudoaneurysms of the femoral artery. Nowadays, it is not uncommon as a consequence of more complex interventional procedures, larger catheters and prolonged anticoagulation treatment. Surgical repair has been mainstay of treatment for pseudoaneurysm. However, recently has it been shown that color Doppler ultrasound-guided direct, noninvasive compression of the pseudoaneurysm stops the blood flow in the communication and lead to pseudoaneurysm clotting and obliteration. We report a case of pseudoaneurysm in femoral artery, which was developed at the right inguinal puncture site in 74 year old male patient with myocardial infarction who had received continuous intravenous infusion of heparin and had undergone primary percutaneous coronary angioplasty and temporary pacemaker insertion treated successfully with color Doppler ultrasound guided direct compression.

An association study with Korean alcoholic patients(n=50) and normal controls(n=53) was performed to find the relationship between catechol-O-methyltransferase(COMT) gene polymorphism and alcoholism using polymerase chain reaction-restriction fragment length polymorphism. When we compared the allele and genotype frequencies of Nla III COMT gene polymorphism in alcoholism and normal controls, there was no significant difference between two groups. Our results do not support an association between the Nla III polymorphism of COMT gene and alcoholism.

Systemic amyloidosis is an uncommon disease characterized by deposits of fibrillar aggregates of monoclonal immunoglobuloin light chains in vital organs. This amyloid deposit cause cardiac or renal dysfunction and ultimately, death. Cardiac amyloidosis may be asymptomatic or important causes of progressive heart failure and refractory arrhythmia. Cardiac involvement from AL amyloidosis is rapidly fatal. The amyloidoses are classified according to the biochemical nature of the fibril-forming protein. Cardiac amyloidosis is common in primary (AL) and heterofamilial amyloidosis and very rare in the secondary (AA) form. As we experienced a case of systemic amyloidosis affected heart, liver and kidney, which was confirmed by histology. We present a 57-year-old female case with literature review.
