The influence of contamination of culture medium with hepatitis B virus on the outcome of in vitro fertilization pregnancies

Article Abstract:

Hepatitis is an inflammation of the liver that can be caused by the hepatitis B virus. It is often transmitted by infected blood or contaminated medical instruments. Human blood serum is used in in vitro fertilization, whereby human eggs are fertilized in culture and then implanted in the female. An outbreak of hepatitis involving 79 women occurred in one clinic because cultures prepared for in vitro fertilization had been infected with hepatitis B. The effects that this contamination had on pregnancy outcome and the fetus were studied. Of the 79 women infected with hepatitis B, 24 became pregnant during infection. Five of these pregnancies were terminated and 19 continued to birth. Twenty-four children were born in the 19 pregnancies. When compared with outcomes of pregnancies where the mothers were not infected with hepatitis B, the percentages of immature, premature and term births were similar. No congenital malformations occurred in any of the children. These results indicate that hepatitis B virus infection during pregnancy does not appear to harm the fetus.

Trauma in pregnancy: Normal Revised Trauma Score in relation to other markers of maternofetal status - a preliminary study

Article Abstract:

The Revised Trauma Score (RTS) may not be useful in determining which injured pregnant women require more lengthy monitoring of their babies. Hospitals use the RTS to evaluate an injured person's condition. Researchers reviewed charts of 30 injured pregnant women who were more than 20 weeks pregnant. All but two had been injured in automobile accidents. All women received the highest RTS score, indicating no serious problems. Despite this, one woman's baby was delivered by emergency cesarean because the placenta had separated from the uterus. Surgery also revealed internal bleeding from a lacerated liver.
