Crossing the quality chasm: a requirement for successful cervical cancer prevention in developing countries.

Disease prevention requires sociopolitical change, which in turn requires the participation of those for whom the change is intended, including demographic groups at high risk for disease, appropriate governmental authorities, and essential health care personnel. Multiparous women of lowest socioeconomic status, the demographic group at highest risk for the development of cervical cancer, lack sociopolitical leverage almost by definition. Pap screening in developing countries is an idea whose time has come, but it is also an ethical imperative currently lacking a substantial sociopolitical constituency. Noncytologic screening methods currently benefit from sponsorship by corporate manufacturers and by donor organizations such as the Bill and Melinda Gates Foundation. Pap screening efforts in developing countries will benefit from the involvement of cytology organizations based in developed countries. Future assessments of the progress of cervical cancer prevention efforts in developing countries will benefit from additional examination of the interactions between quality and sociopolitical obstacles to change. Many of these obstacles will be elucidated by following the money, as well as the science, involved in cervical screening activities.

Population aging in developing countries.

Issues related to population aging--Social Security and pension reform, health care financing and provision, and long-term care--have long been the subject of public debate in the industrialized countries of Europe and North America. Economically less developed regions have been slower to adopt aging as a major public policy concern, despite the fact that older populations in many developing countries are growing more rapidly than are those of industrialized nations. Awareness of issues concerning older populations remains low in many nations, even as the absolute numbers of elderly persons double and even triple. This DataWatch considers trends in the basic demography of aging and mortality/health considerations for developing countries.

A model for establishment of educational programmes in developing countries: the nursing paradoxes in Kuwait.

While American nursing attempts to deal with the multitude of dilemmas that have been plaguing it for decades, many developing countries look to the USA for a nursing model to emulate, and then become lost in this confusion of its nursing profession. However, these countries continue to reach out and seek consultants with educational and practical experience in nursing in the USA, as well as in other developed countries. A paradigm is proposed for use by educators and consultants to help delineate the major issues a developing country has to confront in establishing a stable nursing service. This paradigm is explicated by applying it to the situation in Kuwait, a Fourth World country with many social paradoxes (e.g., rich in economic resources but poor in human resources). Four major paradoxes in nursing are identified by using the proposed paradigm. They are: 1 educational needs vs. educational reality; 2 locals vs. cosmopolitans; 3 role congruency vs. role incongruency; and finally 4 medical vs. nursing conceptual models. Although these paradoxes became manifest through work done by the author in Kuwait, any international health care professional will quickly realize that the prardoxes are not unique to Kuwait but have parallels in many other countries which are at different stages of development.

[Control of iron deficiency in developing countries].

Iron deficiency is the most prevalent nutritional disorder worldwide, especially in developing countries. It occurs when iron absorption cannot compensate iron requirements and losses. Requirements are especially high in pregnant women, infants, young children and adolescents who run a higher risk of being iron-deficient. In developing countries, the main cause of iron deficiency is the low iron bioavailability of the diet. The consequences of iron deficiency are many and serious, affecting not only individuals' health but also the development of societies and countries. The prevention and the control of iron deficiency and anemia in all groups of a population with different iron requirements imply to coordinate different interventions. Iron fortification of staple foods or condiments directed to the whole population is a sustainable and low cost-effective approach. However, at some periods of life, especially during pregnancy and in children from the age of 6 months, iron requirements are high. For pregnant women, the current approach favours the daily iron-folate supplementation during pregnancy but the results in terms of public health are disappointing. The preventive weekly iron-folate supplementation of women during their reproductive life, whose efficacy is recognized, offers a promising alternative; its impact in terms of public health is under current evaluation. For infants and young children, iron fortification of complementary food is effective but this food is generally imported and economically inaccessible to populations with limited resources. The production, by small private units from local products, of complementary foods of low viscosity, good nutritional quality, fortified with vitamins and minerals, and of low cost is at hand in several countries. When complementary foods are not available, the preventive iron supplementation from 6 to 18 months of age has to be advised. This approach should be strengthened by the advantages of the weekly approach. These interventions are more effective when they integrate other approaches like the improvement of the nutritional practices, infection control and the promotion of breast-feeding and when coupled with programs aiming to control other micronutrient deficiencies. The success of most interventions requires the active participation of the individuals. Information and education of the populations, especially through social mobilization campaigns, are essential because iron deficiency induces few visible symptoms, not easily recognizable by individuals. The implementation of national nutrition plans including the control of iron deficiency as one of the priorities and the participation of the public health and education sectors, food industries, the community and the media should contribute to the success of the interventions and to the control of iron deficiency.

Violence against pregnant women in developing countries: review of evidence.

Domestic violence among pregnant women is a global health issue. This study systemically reviews the literature to estimate the prevalence of violence against pregnant women in developing countries. Prevalence of violence among pregnant women in developing countries ranges from 4% to 29%. The main risk factors found for abuse during pregnancy were belonging to a low-income group, low education in both partners, and unplanned pregnancy. Low birth as a consequence of violence is observed. The vulnerability of pregnant women to violence, and to their consequences is an alarming public health issue in developing countries and calls for the design and implementation of better preventive strategies.

Approaches to prevent acute bacterial meningitis in developing countries.

Endemic acute bacterial meningitis of childhood appears to be neglected as a cause of morbidity and mortality in developing countries, probably because it has been overshadowed by the dramatic epidemics of meningococcal disease in sub-Saharan Africa. The available data based on reviews of hospitalized patients suggest that endemic meningitis is mostly a disease of young infants, Streptococcus pneumoniae and Haemophilus influenzae type b being the most important etiologic agents. The epidemiological pattern appears to be different in developing countries, compared with northern Europe or the USA, and closely resembles the early age of onset and high incidence of meningitis observed among the native American populations in Alaska. The mortality from meningitis appears to be much higher in developing countries than in industrialized countries. The availability of vaccines against the pneumococcus and haemophilus, particularly those in which the bacterial polysaccharide is conjugated to a protein, promises protection against systemic bacterial infection from these organisms. The assessment of the efficacy of such vaccines will have to include a close examination of meningitis as an outcome. It is suggested that before such vaccines become available careful clinical and epidemiological studies of meningitis will help both to define the impact of this disease and how to design an intervention strategy.

Clinical research and trials in developing countries.

Over 80 per cent of the global disease burden occurs in developing countries. Yet the proportion of research conducted in these countries is less than 10 per cent of the global research activity. This article emphasizes the need to conduct research in developing countries on locally relevant questions, provides general principles that may assist in establishing such studies, and describes some experiences in the cardiovascular area.

The biological sciences in nursing: a developing country perspective.

AIM: This paper reports a study to inform curriculum development by exploring the contribution of bioscience education programmes to nurses' clinical practice, their understanding of the rationale for practice, and their perceptions of their continuing professional development needs. BACKGROUND: The future of the health services worldwide depends on nurse education programmes equipping practitioners to deliver safe and effective patient care. In the developed world, the structure and indicative content of nursing curricula have been debated extensively. However, despite the rapid expansion in nursing roles brought about by social change, there is little information on the educational needs of nurses in developing countries. METHODS: This study was undertaken in government teaching hospitals in Cape Town, South Africa in 2003. A purposive sample of 54 nurses from a range of clinical settings completed questionnaires and described critical incidents where bioscience knowledge had directed practice. Questionnaires were analysed descriptively, in the main. Analysis of critical incident reports was based on Akinsanya's bionursing model. FINDINGS: Most nurses felt that their understanding of the biological, but not the physical sciences, was adequate or better: all felt confident with their knowledge of anatomy, compared with 57.4% (31/54) for microbiology. Respondents attributed the successes and failures of their education programmes to their teachers' delivery of content, ability to relate to practice and management of the process of learning. The biological, but not the physical, sciences were universally (96-100%) regarded as relevant to nursing. However, the critical incidents and nurses' own reports indicated a need for further education in pharmacology (40/54, 74.1%) and microbiology (29/54, 53.7%). CONCLUSION: To meet the needs of nurses in developing countries, and empower them to meet the increasingly complex demands of their expanding roles, nurse educators need to consider increasing the curriculum content in certain key areas, including pharmacology and microbiology.

Clinical trials in developing countries: a review of the moral issues.

Several ethicists have raised criticisms of various placebo-controlled clinical trials conducted in developing countries between 1995 and 1998. This essay reviews and rejects the arguments that these trials violated basic canons of medical ethics, or constituted exploitation by scientists in advanced countries of subjects in developing countries. A uniform international standard for the evaluation of such trials is proposed, replacing the old standard of voluntary and informed consent with a more focused standard of uncoerced and undeceived consent.

Antibiotic treatment for bacterial meningitis in children in developing countries.

Bacterial meningitis causes 125,000 deaths each year in infants and young children and 96% of these occur in less developed countries where up to 50% of children with this disease die and 25-50% of survivors have neurological sequelae. Although 3rd-generation cephalosporins are optimal empirical therapy for bacterial meningitis, they are unaffordable in many developing countries. The majority of children worldwide are currently treated with cheaper alternatives. This paper reviews the challenges facing clinicians treating bacterial meningitis in developing countries, highlighting the problem of changing patterns of antibiotic resistance. In particular, it details the evidence for the use of chloramphenicol and 3rd-generation cephalosporins.

Adolescent knowledge and use of injectable contraceptives in developing countries.

PURPOSE: To review recent survey data on knowledge and use of injectable contraceptives among adolescents and young women in developing countries. The proportion of adolescents who are aware of this method, who have ever used it, and who are currently using the method, are described. Use of the injection is compared to overall use of any method, as well as to use of two other specific methods, the contraceptive pill and the condom. METHODS: The data reported here come from a series of nationally representative surveys carried out in 25 developing countries, in the mid to late 1980s, as part of the Demographic and Health Surveys (DHS) project. These are surveys of 5,000-10,000 women aged 15-49 years that obtain information on whether women have heard about each specific method, as well as on ever-use and current use of contraception. The data presented here are compiled from published sources, and focus on currently married young women (15-24 year olds), and adolescents (15-19 year olds). RESULTS: Although the injection is recognized by a moderately high proportion of young women and adolescents (40-70% in most countries), use of this method is extremely low in almost all countries. The exceptions, based on DHS data, are 3 Asian countries (Indonesia, Sri Lanka and Thailand) and to a lesser extent, two Latin American countries (Colombia and Mexico). Other countries with moderately high levels of use of Depo-Provera, based on other sources, are China, Jamaica and New Zealand. However, apart from these few countries, when adolescents and young women do choose to use contraception, it is the pill that they are much more likely to choose. CONCLUSIONS: Problems of availability of supplies of the injection may explain some of the observed variation in levels of use of this method. Supplies are mostly provided by international donor agencies such as United Nations Fund for Population Activities and International Planned Parenthood Federation. The lack of approval of the method by the United States until recently also probably had a negative effect on the likelihood of some other governments approving this method or promoting it. Now, with the approval of the United States, supplies may become more available and there may be a greater willingness to use Depo-Provera and other injectables in the developing countries.

Estimates of acute pesticide poisoning in agricultural workers in less developed countries.

The benefits of crop protection products have to be balanced against the risks to farmers and other agricultural workers handling and applying them. The extent of acute pesticide poisoning in these workers, particularly in less developed countries, has often been based on inadequate information. A number of approaches have been taken by researchers to acquire information on pesticide poisoning. These have resulted in worldwide (global) estimates and regional, localised or field assessments. The methods include descriptive epidemiology, cross-sectional and case studies. Attempts to estimate global pesticide poisonings have often been based upon extrapolations and assumptions from chemical-related fatalities in a small number of countries; such estimates do not provide reliable data. Epidemiological studies, relying mainly on hospital and poison centre data, have been biased towards the more severe poisonings, whereas field studies indicate that occupational pesticide poisoning is associated with less severe and minor effects. Many reports do not adequately distinguish between intentional, accidental and occupational pesticide poisoning statistics or are dominated by cases of intentional (suicidal) poisoning which, by their nature, result in severe or fatal results. The majority of reports do not adequately describe whether individual cases are minor, moderate or severe poisonings. In order to assess information on acute pesticide poisoning in agricultural workers in less developed countries and to draw conclusions on the extent and severity of occupational poisoning, the most recent (post-1990) literature was reviewed. Data were also derived from the World Health Organization (WHO), United Nations Environment Programme (UNEP) and the International Labour Office (ILO). The collected information was analysed to assess the extent and severity of occupational acute pesticide poisoning in less developed countries. Occupational acute pesticide poisonings in these countries are a small proportion of overall reported poisoning and are associated with the more minor effects of pesticides. They are a small proportion (<1-4%) of the several million cases of occupational injuries and ill health in agricultural workers worldwide. However, improvements are required for the collection of acute pesticide poisoning data in less developed countries and in the verification of the circumstances of poisonings and their relative severity. There is the need to move away from further attempts to estimate global data and concentrate instead on obtaining reliable data from realistic crop protection activities.

Epidemiology and prospects for prevention of disease due to Haemophilus influenzae in developing countries.

Haemophilus influenzae is an important cause of meningitis and severe cases of lower respiratory infection (LRI) in children in developing countries. In children with meningitis, H. influenzae type b organisms are the most frequently encountered serotype, but in some countries type a strains are also implicated. In children with LRI, type b organisms are also important, but the proportion of organisms with other serotypes and non-typable strains is greater than that associated with cases of meningitis. In developing countries, nearly all cases of H. influenzae meningitis and a substantial fraction of cases of LRI occur in children younger than one year of age. This age distribution is younger than that seen in the continental United States, where more than one-half of the cases of invasive H. influenzae disease are in children older than one year of age. New type b polysaccharide-protein conjugate vaccines are immunogenic in infants as young as two months of age and offer the promise of preventing H. influenzae type b disease in infants younger than one year of age. However, for developing countries, more complete data defining the populations at risk, the immunogenicity of candidate vaccines in children in different geographic regions, and the serotypes of the infecting organisms will be needed before successful cost-effective vaccination strategies can be devised and implemented.

Behavioral and psychological symptoms of dementia in developing countries.

BACKGROUND: Little is known about the prevalence of, or associations with behavioral and psychological symptoms of dementia (BPSD) in developing countries. METHODS: Individuals diagnosed as having dementia according to DSM-IV criteria (mild and moderate cases as defined by the Clinical Dementia Rating scale only), together with their main caregiver, were recruited from 21 centers in 17 developing countries. People with dementia were directly assessed with the Community Screening Interview for Dementia and the Geriatric Mental State Schedule (GMS); GMS data were processed by the AGECAT computer program to yield diagnostic information on 8 psychiatric syndromes. Caregivers answered direct questions about behavioral symptoms of dementia (BSD) and completed the Zarit Burden Inventory. RESULTS: At least one BSD was reported in 70.9% of the 555 participants. At least one case-level AGECAT psychiatric syndrome (not including the organic syndrome) was exhibited by 49.5% of people with dementia. Depression syndromes (43.8%) were most common followed by anxiety neurosis (14.2%) and schizophreniform/paranoid psychosis (10.9%). Caregivers were more likely to report BSD in people with dementia who were married, younger and better educated. More advanced dementia, poorer functioning and the presence of depression or anxiety were each associated with BSD. BSD, and psychiatric syndromes (anxiety neurosis and schizophreniform/paranoid psychosis) predicted caregiver strain after controlling for cognitive impairment. BPSD are poorly understood, leading to shame and blame. CONCLUSIONS: BPSD are common among people with dementia in developing countries, though we found marked regional variations. Representative population studies are needed to clarify prevalence and impact, but our research suggests considerable unmet need, with much scope for intervention. Raising awareness of the problem should be the first step.

Radiation-sparing managements for cervical cancer: a developing countries perspective.

Cervical cancer is the seventh most frequent cancer worldwide but more than 80% of cases occur in developing countries. Till date, radiation therapy with external beam and brachytherapy remains as the core treatment for most stages of cervical cancer. However, radiation treatment protocols and equipment modelled on the best developed countries can be seldom applied directly to developing countries owing to financial constraints and lack of qualified personnel, thus, a substantial proportion of patients do not have access to even palliative radiation therapy. Treatment options when the standard therapy is either not available or difficult to reproduce in particular settings is highly desirable with the potential to save lives that otherwise could be lost by the lack of adequate treatment. These options of treatment ideally had to have show, 1) that these are not inferior to the "standard" in terms of either survival or quality of life; 2) that these can be delivered in settings were the "standard" is not available or if available its quality is poor; and 3) that the treatment option be accepted by the population to be treated. Based on these considerations, it is obvious that cervical cancer patients, particularly those who live in countries with limited resources and therefore may not have sufficient radiation therapy resources are in need of newer therapeutical options. There is now a considerable amount of information emanating from clinical studies where surgery has a major role in treating this disease. These forms of "radiation-sparing" treatments include total mesometrial resection that could make unnecessary the use of adjuvant radiation; neoadjuvant chemotherapy that could avoid the use of adjuvant radiation in around 85% of patients and preoperative chemoradiation that could make brachytherapy dispensable. The feasibility and therapeutical value of these potential forms of management need to be prospectively evaluated.

Management of children with prolonged fever of unknown origin and difficulties in the management of fever of unknown origin in children in developing countries.

This is Part II of a 2-part paper on fever of unknown origin (FUO) in children. It examines the aetiology and management of prolonged FUO in children and the difficulties in the management of FUO in children in developing countries. Part I of this paper discussed acute FUO in children and was published in the March 2001 issue of Paediatric Drugs. Prolonged FUO is documented fever of more than 7 to 10 days which has no apparent source and no apparent diagnosis after 1 week of clinical investigations. About 34% of cases of prolonged FUO are caused by infections, with bacterial meningitis and urinary tract infection accounting for about 6.5 and 11.4%, respectively, of cases attributable to infections. Chronic infections, particularly tuberculosis and 'old' disorders such as Kawasaki disease, cat-scratch disease and Epstein-Barr virus infection presenting with 'new' manifestations, collagen-vascular diseases and neoplastic disorders are the other issues of major concern in prolonged FUO. Overall, however, there is a trend towards an increased number of undiagnosed cases. This is due to advancements in diagnostic techniques, such that illnesses which were previously common among the causes of prolonged FUO are now diagnosed earlier, before the presentation becomes that of prolonged FUO. Clinical examination supplemented with laboratory tests to screen for serious bacterial infections should be the mainstay of initial evaluation of children with prolonged FUO. Use of scanning techniques (such as computerised tomography and ultrasound) as additional supplements to this clinical examination may allow for the earlier diagnosis of causes of prolonged FUO in children such as 'occult' abdominal tumours. A common error in management of children with prolonged FUO is the failure to perform a complete history and physical examination; repeated clinical examination and continued observation are of paramount importance in the diagnosis of difficult cases. Major difficulties in the management of FUO in children in developing countries include constraints in the availability and reliability of laboratory tests, cost, misuse of antibiotics and difficulties encountered in the diagnosis of malaria and typhoid fever. Malaria and typhoid fever are major aetiological considerations in both acute and prolonged FUO in children in developing countries. The newer quinolones may hold great promise for the treatment of serious bacterial infections, including meningitis, which are associated with prolonged FUO in developing countries.

Technology and neurosurgery in developing countries: experience and present situation in Morocco.

OBJECTIVE: The high cost of technology is considered to be the determining factor slowing the expansion of modern neurosurgery in many developing countries. The literature dedicated to this topic rarely proposes internal solutions whereby affected countries can overcome this economic impediment. Certain articles cite inevitable obstacles, and the neurosurgeons of these countries can become disheartened when these articles conclude with calls for foreign help as the only approach to the development of neurosurgery. METHODS: Morocco is presented as an example of a developing country in which neurosurgery has become well established in the past 30 years, using a program based on four guidelines, as follows: 1) encouraging the local training of young neurosurgeons, 2) organizing and promoting neurosurgery, 3) integrating the development of neurosurgery into the health care pyramid system, and 4) stimulating research on local pathological conditions. RESULTS: Because of the internal planning efforts stimulated by the first national neurosurgeons, Morocco has progressed from 2 underequipped neurosurgical services and 5 neurosurgeons in 1968 to 12 well-equipped services and 80 neurosurgeons in 1998. The main benefits of this progress are discussed. CONCLUSION: Neurosurgery in developing countries can be promoted if the first working neurosurgeons take up their responsibilities as pioneers. This role requires that they initiate the training of young neurosurgeons as soon as possible and that they find in the local conditions the necessary factors to promote neurosurgery and to integrate it into the health care development of their country.

Hematologic disorders of children in developing countries.

This article outlines a few of the hematologic problems that are particular to developing countries, particularly those of the tropics. Because of globalization and the increasing movement of populations, hematologists in wealthier countries must be aware of the general patterns of hematologic change in the important infectious diseases that are common in developing countries. Their manifestations are protean, and any of these diseases, malaria in particular, may present in ways that are atypical from the standard textbook descriptions. In short, the handling of hematologic disorders in developing or tropical countries is no longer confined to the physicians who work in these countries; these diseases are now part of the work of every hematologist.
