two studies, pneumococcal polysaccharide (Pnc PS) vaccine was given to more than 400 pregnant Papua New Guinean women. No deleterious effects were found. The vaccine prevented acute lower respiratory infection (ALRI) among offspring in utero or aged 1-17 months at the time of maternal immunisation, suggesting protection through breast feeding. Serum IgG antibody titres were higher in vaccinated than unvaccinated groups for 2-4 months after delivery and no immune suppression, evaluated by the response to subsequent Pnc PS vaccination, was detected. Breast milk IgA to four serotypes was 1.1-1.8 times higher in immunised than unimmunised women for 6 months postpartum. Given results from several developing countries, large-scale safety and efficacy trials are now justified. Postpartum maternal immunisation is another intervention under consideration.

OBJECTIVES Despite few data, the treatment of syphilis in pregnant women using a single dose of benzathine penicillin is the standard of care in many resource-poor settings. We examined the effect of various doses of benzathine penicillin on pregnancy loss among women with a positive Rapid Plasma Reagin (RPR) test result in a rural South African district. METHODS All pregnant women making their first antenatal care visit during pregnancy were screened for syphilis using the RPR test. Those testing positive were counselled to receive three weekly doses of benzathine penicillin, and received a partner notification card. Pregnancy outcomes were determined from facility records or home visits where necessary. RESULTS Of 8917 women screened, 1043 (12%) had reactive syphilis serology; of those with titre data available, 30% had titres of 1:8 or greater. While 41% (n = 430) of women received all three doses as counselled, 30% (n = 312) received only one dose, and 20% (n = 207) did not return to the clinic to receive treatment. Among the 947 women with pregnancy outcome data available, there were 17 miscarriages and 48 perinatal deaths observed. There was a strong trend towards reduced risk of pregnancy loss among women receiving multiple doses of penicillin (adjusted OR for perinatal mortality for each additional dose received, 0.63; 95% CI, 0.48-0.84). CONCLUSIONS While this association requires further investigation, these results suggest that there may be substantial benefit to providing multiple doses of benzathine penicillin to treat maternal syphilis in this setting.

We examine the newly developed international diversification instruments–iShares traded on the American Stock Exchange. Given the fact that iShares can be created and redeemed at will, the daily price of an iShare is expected to be equal to the daily portfolio value of the underlying assets in the home-country market. Therefore, theoretically, iShare pricing should be influenced by the risk from the iShare's home-country market and not the risk from the US market, per se. We evaluate the risk exposure of iShare prices to the US market (non-fundamental effect) as well as the home-country market (the fundamental effect). We find that most iShare returns are significantly influenced by and sensitive to the US market risk. Moreover, the US market appears to be the key permanent driving factor and the home-country market is a pronounced transitory driving force for iShare prices. These findings indicate the presence of limits of international arbitrage for iShares. As a result, the international diversification benefits of iShares become questionable.
