Incidence of parvovirus B19 infection among an unselected population of pregnant women in the Netherlands: A prospective study.

Objective: To evaluate seroprevalence of anti-parvovirus B19 IgG immunoglobulins and the rate of seroconversion in seronegative pregnant women.

Design: Prospective assessment of anti-parvovirus B19 IgG immunoglobulins in an unselected population of pregnant women booked for antenatal care from 1998 to 2000.

Setting: Maternity departments of an academic hospital and four affiliated teaching hospitals in the Netherlands.

Rate of fall-applied liquid swine manure: effects on runoff transport of sediment and phosphorus.

Reducing the delivery of phosphorus (P) from land-applied manure to surface water is a priority in many watersheds. Manure application rate can be controlled to manage the risk of water quality degradation. The objective of this study was to evaluate how application rate of liquid swine manure affects the transport of sediment and P in runoff.

[Parvovirus B19 infection in pregnancy: a cause of non-immune hydrops fetalis].

Four pregnancies, in two women aged 39 and two women aged 34 years respectively, were complicated by foetal parvovirus B19 infection. First-trimester intrauterine death resulting from multiple congenital anomalies was diagnosed in one patient with proven foetal parvovirus B19 infection. In three patients foetal hydrops was found in the second trimester with variable clinical course.

The effect of white light exposure on the rabbit eye lens as measured by fluorophotometry and spectrophotometry.

Fluorophotometry and spectrophotometry of the rabbit lens were performed after white light exposure to detect possible changes in the lens before damage could be seen by biomicroscopic slit lamp examination. In nine rabbits the lens of one eye was exposed to white light and that of the fellow eye was used as a control. The incident light power was 240 mW for 90 min on a lenticular area of 3 mm2.
