RESUMEN

Studies of archaeological and palaeontological bone assemblages increasingly show that the historical distributions of many mammal species are unrepresentative of their longer-term geographical ranges in the Quaternary. Consequently, the geographical and ecological scope of potential conservation efforts may be inappropriately narrow. Here, we consider a case-in-point, the water deer Hydropotes inermis, which has historical native distributions in eastern China and the Korean peninsula. We present morphological and metric criteria for the taxonomic diagnosis of mandibles and maxillary canine fragments from Hang Thung Binh 1 cave in Tràng An World Heritage Site, which confirm the prehistoric presence of water deer in Vietnam. Dated to between 13 000 and 16 000 years before the present, the specimens are further evidence of a wider Quaternary distribution for these Vulnerable cervids, are valuable additions to a sparse Pleistocene fossil record and confirm water deer as a component of the Upper Pleistocene fauna of northern Vietnam. Palaeoenvironmental proxies suggest that the Tràng An water deer occupied cooler, but not necessarily drier, conditions than today. We consider if the specimens represent extirpated Pleistocene populations or indicate a previously unrecognized, longer-standing southerly distribution with possible implications for the conservation of the species in the future.

RESUMEN

Described at the end of the twentieth century, the large-antlered or giant muntjac, Muntiacus gigas (syn. vuquangensis), is a Critically Endangered species currently restricted to the Annamite region in Southeast Asia. Here we report subfossil evidence of giant muntjac, a mandible fragment dated between 11.1 and 11.4 thousand years before present, from northern Vietnam. We describe morphological and metric criteria for diagnosis and consider the specimen in the context of regional archaeological and palaeontological records of Muntiacus. We then consider the palaeoenvironmental context of the specimen and the implications for habitat requirements for extant populations. The new specimen extends the known spatial and temporal range of giant muntjacs in Vietnam and is further evidence that this species was more widely distributed in the Holocene than current records indicate. While regional proxy evidence indicates a drier climate and more open woodland habitats at the onset of the Holocene, contextual evidence indicates that the specimen derived from an animal inhabiting limestone karst forest. This record also supports the assertion that remnant populations are in a refugial state, as a result of anthropogenic pressures, rather than representing a centre of endemism. These facts underscore the urgent need for the conservation of remaining populations.

RESUMEN

OBJECTIVE: To compare women's acceptance of misoprostol-only medical termination of pregnancy (TOP) with surgical TOP. DESIGN: Prospective cohort study. SETTING: Termination of pregnancy clinics in New Delhi, Mumbai, Hanoi, Tbilisi, Trivandrum and Yerevan. POPULATION: Women requesting TOP, at 63 days of gestation or less, at study sites where both medical and surgical methods were available. METHODS: Serial surveys eliciting measures of women's satisfaction and acceptance of TOP method were administered. Data were analysed using cross-tabulation and logistic regression to determine if TOP method was predictive of acceptability. MAIN OUTCOME MEASURES: Patient acceptance. RESULTS: High acceptability of both surgical and misoprostol-only TOP. CONCLUSIONS: Where medical TOP with mifepristone is not available, misoprostol-only medical TOP is acceptable to women who have the choice between medical or surgical techniques.

RESUMEN

OBJECTIVE: To compare 400 and 800 microg sublingual or vaginal misoprostol 24 hours after 200 mg mifepristone for noninferiority regarding efficacy in achieving complete abortion for pregnancy termination up to 63 days of gestation. DESIGN: Placebo-controlled, randomised, noninferiority factorial trial, stratified by centre and length of gestation. Misoprostol 400 or 800 microg, administered either sublingually or vaginally, with follow up after 2 and 6 weeks. SETTING: Fifteen obstetrics/gynaecology departments in ten countries. POPULATION: Pregnant women (n = 3005) up to 63 days of gestation requesting medical abortion. METHODS: Two-sided 95% CI for differences in failure of complete abortion and continuing pregnancy, with a 3% noninferiority margin, were calculated. Proportions of women with adverse effects were recorded. OUTCOME MEASURES: Complete abortion without surgical intervention (main); continuing live pregnancies, induction-to-abortion interval, adverse effects, women's perceptions (secondary). RESULTS: Efficacy outcomes analysed for 2962 women (98.6%): 90.5% had complete abortion after 400 microg misoprostol, 94.2% after 800 microg. Noninferiority of 400 microg misoprostol was not demonstrated for failure of complete abortion (difference: 3.7%; 95% CI 1.8-5.6%). The 400-microg dose showed higher risk of incomplete abortion (P < 0.01) and continuing pregnancy (P < 0.01) than 800 microg. Vaginal and sublingual routes had similar risks of failure to achieve complete abortion (P = 0.47, difference in sublingual minus vaginal -0.7%, 95% CI -2.6-1.2%). A similar pattern was observed for continuing pregnancies (P = 0.21). Fewer women reported adverse effects with vaginal than sublingual administration and with the 400-microg dose than the 800-microg dose. Of the women, 94% were satisfied or highly satisfied with the regimens, 53% preferred the sublingual route and 47% preferred the vaginal route. CONCLUSIONS: A 400-microg dose of misoprostol should not replace the 800-microg dose when administered 24 hours after 200 mg mifepristone for inducing abortion in pregnancies up to 63 days. Sublingual and vaginal misoprostol have similar efficacy, but vaginal administration is associated with a lower frequency of adverse effects.

RESUMEN

This paper begins with an observation that during the past two decades HIV/AIDS has emerged as a new public health priority in Vietnam and has commanded increasing attention and resources from both the government and the donor community. By juxtaposing HIV/AIDS with family planning, another social and health priority that preceded, and overlapped with, HIV/AIDS for a large part of the 1990s, we show two major gaps that have undermined both programmes. One is the lack of a strong civil society, that could have served as advocates for change, especially outside the government and the donor community. The other is the desire for control of women's bodies and sexuality that has been driven by the ever shifting project of nation building. We argue that these two major gaps represent more continuity than discontinuity in the way sexual and reproductive health issues are approached in Vietnam despite the seeming shift in priority that the emergence of HIV/AIDS suggests.
