The aim of the study was to evaluate the significance of unexplained elevated mater- nal serum alpha-fetoprotein in singleton pregnancies as a prediction of fetal risk. The inclusion criteria for patents with unexplained MSAFP elevations were a MSAFP level 2.0 or greater multiples of the median ( MoM ), a single gestation, a confirmed gestatio- nal age and no fetal malformation or death on ultrasonography. In this study, 991 woman who attended the antenatal clinic at Taejeon Eul Ji Hospital from March, 1996 to March, 1997 were reviewed and data from 79 women with elevated maternal serum alpha-fetoprotein levels were analysed. The 67 of 79 patients with elevated maternal serum alpha-fetoprotein levels had on unexplained elevated MSAFP level. 13 women could not follow up. 54 pregnant women with unexplained elevated MSAFP levels were classified as the index group of singleton pregn- ancy and were matched against a control group. 108 patients with MSAFP levels 0.5 to 2.0 MoM served as control group. The incidence of antepartum hemorrhage ( placental previa ), preterm labor, intrauterine growth retardation ( IUGR ), low birth weight and pregnancy induced hypertension ( PIH ) in two groups was analyzed and the results was subjected to Fisher's Exact Test. None of the patients in the index group had chromosomal abnormalites or birth defect. IUGR occurred in 7 ( 12.96% ) of the index group babies but in only 3 ( 2.78% ) in the control group ( p < 0.02 ). preterm labor occurred in 5 ( 9.26% ) in the index group compared with 2 ( 1.85% ) in the control group ( p < 0.05 ). low birth weight occurred in 3 ( 5.5% ) of the index group babies and in 1 ( 0.9% ) in the control group ( p < 0.1 ). This study suggests that patients with unexplained midtrimester elevations of MSAFP are increased risk for IUGR, preterm labor. But no significance differences were observed in the incidence of low birth weight, antepartum hemorrhage ( placental previa ), PIH.

BACKGROUND AND OBJECTIVES: The relationship of cold pressor, hyperventilation and exercise test responses to circadian patterns and types of angina in vasospastic angina have still not been known. The aim of this study was to identify subgoups of patients who have similar clinical features and provocation test response. MATERIALS AND METHODS: Twenty-one consecutive patients with pure vasospastic angina were studied. Six exercise tests were performed in the early morning, late morning, and late afternoon in consecutive days, and 2 hyperventilation tests and 2 cold pressor tests in the early morning. Circadian distribution and types of angina(at rest, on physical activity or both) were evaluated by clinical history, clinical records and ambulatory ECG recordings during admission and follow-up periods(mean 19+/-9 months). RESULTS: Three patterns of circadian distribution of anginal attacks were identified during all observation periods together(morning and night: MN n=, morning and afternoon or evening: M+/E n=, morning, night and afternoon and/or evening: MN+/E n=1). Exercise test was positive in 36%(40/111) without circadian variation, hyperventilation test in 66%(23/35) and cold pressor test in 6%(2/33). Neither hyperventilation test nor cold pressor test was related to circadian patterns, types or activity of angina, or numbers of spastic artery. But positive exercise test increased significantly in patients with angina on physical activity(43% vs 21%, p<0.05), high activity(57% vs 18%, p<0.01), multivessel spasm(50% vs 27%, p<0.05 ) and circadian patterns of M+/E and MN+/E(29%, 55% vs 4%, p<0.05, p<0.01). All patients with MN had rest angina and single vessel spasm. All 6 patients with M+/E had angina both at rest and on physical activity and 5 single vessel spasm. Eight of 11 patients with MN+/E had angina both at rest and on physical activity and 8 multivessel spasm. CONCLUSION: These findings suggest that hyperventilation test is highly sensitive in vasospastic angina without any relationship to clinical features, but exercise test response is related well to circadian patterns of angina attacks which are associated with characteristic clinical features.
