Primary Presentation of Pulmonary Hypertension in the Peripartum: Preparing for Patients With Eisenmenger Physiology.

A Bosnian woman at 20 weeks' gestation presented with dyspnea and hypoxia. She was diagnosed with Eisenmenger physiology with severe pulmonary hypertension, ventricular septal defect, and patent ductus arteriosus. Given high maternal mortality, coordination of care with a multidisciplinary team approach may allow for best possible outcomes. (Level of Difficulty: Intermediate.).

Explanations of the fertility crisis in modern societies: a search for commonalities.

Near-global fertility decline began in the 1960s, and from the 1980s an increasing number of European countries and some Asian ones achieved very low fertility (total fertility below 1.5) with little likelihood of completed cohort fertility reaching replacement level. Earlier theory aiming at explaining this phenomenon stressed the incompatibility between post-industrial society and behaviour necessary for population replacement. Recent theory has been more specific, often concentrating on the current Italian or Spanish situations or on the contrast between them and the situation in either Scandinavia or the English-speaking countries, or both. Such an approach ignores important evidence, especially that from German-speaking populations. The models available concentrate on welfare systems and family expenses, omitting circumstances that may be unique to individual countries or longer-term factors that may be common to all.

Transesophageal echocardiography-guided placement of internal jugular percutaneous venovenous bypass cannula in orthotopic liver transplantation.

Venovenous bypass has improved patient survival and decreased morbidity and mortality in the field of orthotopic liver transplantation. The standard at many transplant centers is the use of the internal jugular percutaneous venovenous bypass cannulae (PVVBC) for venous return to the patient. Placement of these large (18F) PVVBC may lead to several complications and requires confirmation before use. Use of transesophageal echocardiography, an effective and rapid method to guide placement of the PVVBC and minimize potential complications associated with insertion of the device, is described.

Searching for an optimum solution to the Bangladesh arsenic crisis.

Searching for an optimum solution to the Bangladesh arsenic crisis: Thirty years ago Bangladesh experienced very high levels of infant and child mortality, much of it due to water-borne disease in deltaic conditions where surface water was highly polluted. In what appeared to be one of the great public health achievements, 95% of the population were converted to drinking bacteria-free tubewell water from underground aquifers. Recently, it has been shown that perhaps 20% of this water is arsenic contaminated and alternatives to tubewell water have been sought. This paper reports on two national surveys collaboratively carried out in 2000 by the Health Transition Centre, Australian National University and Mitra and Associates, Dhaka: A census of tubewells and a household survey of tubewell use and arseniosis. The study found that the tubewell revolution has been promoted not only by health considerations but also by the demand for a household water facility and the desire by women to reduce workloads associated with using surface water. Because of this, and because the population had absorbed the message about safe tubewell water, it is argued that the movement away from the use of tubewell water should be as limited as possible, even if this means using safe tubewells which are often found in the neighbourhood. To enable such a move the most urgent need is not changing the source of water but comprehensive national water testing providing essential information to households about which wells are safe and which are not.

AIDS in Papua New Guinea: situation in the Pacific.

There has long been reason to anticipate a major heterosexual epidemic of acquired immunodeficiency syndrome (AIDS) in Papua New Guinea (PNG) and probably in the rest of Melanesia. From the social and behavioural perspectives, Melanesia is strikingly similar to other areas of the world with serious epidemics of AIDS. High levels of other sexually transmitted infections indicate behaviour patterns that would also facilitate transmission of human immunodeficiency virus (HIV) and presence of cofactors for HIV infection. Low levels of male circumcision parallel the situation in other epidemic areas. Near-parity by sex in cases reported so far in PNG is evidence that primary infection is largely heterosexual. The late start of a major epidemic in PNG can probably be attributed to: (a) the relatively small aggregation of people in urban centres (even Port Moresby has only one-quarter of a million people); (b) a highway system that does not network across the whole country; (c) limited size of the organized commercial sex sector; and (d) possibly low level of chancroid to act as a cofactor. The situation is now changing. Over the last seven years, HIV infection, probably the highest in Port Moresby and mostly measured there, has been rising by about 60% per annum. This rise is genuine and, if sustained, would infect 10% of the adult population of PNG in little more than 12 years. Some countries of sub-Saharan Africa have witnessed such exponential rises.

The future of family planning programs.

National family planning programs have been an important instrument in accelerating global fertility decline and in restricting ultimate world population to a level probably below ten billion. They began to come into being after 1950 and will probably go out of existence in most of the world's regions by 2050. The archetypal programs were instituted in Asia and North Africa. The end of the twentieth century is an appropriate half-way mark at which to evaluate the twentieth-century programs and to assess what changes in them will be needed for the twenty-first century. Some changes are necessary because dramatic events have occurred: (1) long-term replacement-level fertility has been attained in most of East Asia and some of Southeast Asia, and accordingly, some programs there are being phased out; (2) mainland South Asian fertility has been slower to decline; (3) international donor funding is diminishing and may not be significant during much of the twenty-first century; (4) the 1994 International Conference on Population and Development held in Cairo called for a radical change in programs away from demographic aims and toward reproductive health and the improvement of the situation of women; and (5) the future family planning frontier will be sub-Saharan Africa, for which radically new types of programs may have to be developed. These issues were discussed in January 2000 at a conference held in Dhaka, Bangladesh. A selection of contributions to the conference is published here. This article provides an overview of the issues based partly on this selection and partly on the discussions that took place at the conference.

Africa: the new family planning frontier.

Sub-Saharan Africa will be the family planning frontier of the twenty-first century. Fertility levels and population growth rates are still high, and family planning programs suited to the region are still being developed. Nevertheless, by the end of the twentieth century, fertility transition was under way in Southern Africa and a few countries elsewhere. Successful regional family planning in the twenty-first century will depend upon stronger political leadership, the development of family planning programs that meet the needs of all segments of society and not only currently married women, assistance to the market, and a recognition of the central importance of hormonal methods, especially injectables. Problems include stagnation in economic growth and in child mortality decline, as well as the persistence of the AIDS epidemic.
