OBJECTIVE To assess the diagnostic value of three vaginal markers-insulin-like growth factor binding protein 1 (= IGFBP1), diamine-oxidase (= DAO) and pH-for diagnosis of the premature rupture of membranes. STUDY One hundred pregnant women participated in the study. They were divided into three groups: group A (34 cases with intact membranes), group B (35(More)
Non immune hydramnios and fetal ascite are demonstrated at 31 weeks gestation. There is no familial story. All etiologic investigations (repeated ultrasonographic examinations, amniocentesis) are negative. The delivered girl has a normal development. She presents a congenital ascite and edema. The diagnosis of sialidosis (mucolipidosis type I) is supported(More)
The aim of this prospective study was to establish complementary data of uteri exposed to diethylstilbestrol (DES) in utero for transvaginal analysis and vascularity changes during the menstrual cycle. A total of 28 women with DES-exposed uteri were compared with 60 non-exposed women. Transvaginal ultrasound and colour Doppler imaging were performed on days(More)

Premature rupture of membranes (PROM) is sometimes difficult to diagnose. This report proposes the use of alpha-feto-protein (AFP) values in vaginal secretions for diagnostic tests. Our investigation took place in two separate phases. The first phase validated the AFP test using an immuno-enzymatic assay method and determined a threshold value from a sample(More)
We propose a clientele-based model of the yield curve and optimal maturity structure of government debt. Clienteles are generations of agents at different lifecycle stages in an overlapping-generations economy. An optimal maturity structure exists in the absence of distortionary taxes and induces efficient intergenerational risksharing. If agents are more(More)
BACKGROUND To study the comparative diagnostic value in premature rupture of membranes (PRM) of three amniotic components: fetal fibronectin (fFN), alphafetoprotein (AFP), diamino-oxydase (DAO). METHODS 131 pregnant women took part in our prospective study. Three samples were obtained successively for each patient in a random order. Two clinical(More)
Measurements are reported of NMR relaxation times (T2) on hydrogen in water of isotonic NaCl solutions and of normal human amniotic fluid in which known concentrations of meconium (fetal feces) were dissolved. Magnetic fields for resonance of 23.5 X 10(3) and 0.6 oersteds were used. From the measured T2 values, reliable estimates of meconium concentrations(More)
The goal of this paper is to analyze the extent of international risk sharing in the presence of trade costs and credit constraints, focusing on three issues : how the frictions play, how they interact and whether they can be disentangled empirically. I build a simple model of a two-country endowment economy featuring both shipping costs and non-enforceable(More)

Positive investment comovements across OECD economies as observed in the data are difficult to replicate in open-economy real business cycle models, but also vary substantially in degree for individual country-pairs. This paper shows that a two-country stochastic growth model that distinguishes sectors by factor intensity (capital-intensive vs.(More)
