The use of fluoroquinolones in sexually transmitted diseases in Southeast Asia.

This paper reviews the use of the fluoroquinolone antibiotics in the management of sexually transmitted diseases (STD) in Southeast Asia. Numerous clinical trials performed in the region have shown that the quinolones are highly effective for treating uncomplicated gonorrhoea. Norfloxacin 800 mg, ofloxacin 400 mg, ciprofloxacin 250 mg, and pefloxacin 400 mg in single oral doses have yielded excellent clinical results. Overall cure rates were greater than 95%, with full eradication of penicillinase-producing Neisseria gonorrhoeae in all studies. Strains of gonococci resistant to the quinolones have already emerged and should be closely monitored. However, this has not become a serious problem to date, as large scale evaluation has shown that the quinolones remain highly efficacious for the treatment of gonorrhoea. These antibiotics in single doses are not effective for postgonococcal urethritis (PGU); therefore, concomitant use of an antichlamydial regimen for all patients with gonorrhoea is recommended. The quinolones are also highly effective for chancroid. Excellent results, with cure rates approaching 100%, were achieved with single oral doses of ciprofloxacin 500 mg, norfloxacin 800 mg, and ofloxacin 400 mg. Widespread use of these drugs in STD treatment regimens may be one of the main factors causing a dramatic decline in the number of cases of chancroid seen in recent years. Ofloxacin in variable dosages for a period of 10 to 21 days was found to be effective in nongonococcal urethritis (NGU). However, when compared with the tetracyclines, it is less cost effective and can thus be regarded as an alternative treatment for NGU.

Is the childhood asthma questionnaire a good measure of health-related quality of life of asthmatic children in Asia?: validation among paediatric patients with asthma in Singapore.

BACKGROUND: Health-related quality of life (HR-QOL) is an important outcome in the treatment of chronic childhood diseases such as asthma. However, this measure is rarely used in young children in Asia because of the difficulty of obtaining valid, reliable instruments that are developmentally and culturally suitable. OBJECTIVES: To select, culturally adapt and validate a disease-specific HR-QOL questionnaire (Childhood Asthma Questionnaire [CAQ]-B) for asthmatic children aged 7-11 years in Singapore, and to understand the relationship between patient-reported HR-QOL domains and physician- or caregiver-rated severity. METHODS: A literature review was conducted to shortlist questionnaires based on pre-specified criteria. A pre-test was conducted to assess suitability and relevance of the questionnaires in Singapore. The selected questionnaire (CAQ-B) was then adapted to more closely reflect the local culture, climate, school system and terminology. Cross-sectional validation was conducted. All asthmatic patients aged 7-11 years attending the respiratory clinic in a paediatric hospital, and without co-morbidities that could significantly affect their HR-QOL, were invited to participate. Patients and their parents or caregivers were asked to complete the relevant sections of the questionnaire before their medical consultation. The child's severity of asthma was rated by the attending physician according to guidelines from the Singapore Ministry of Health. Correlations between the child-reported CAQ-B outcomes and clinical ratings of severity by both parents and physicians were investigated. Internal reliability was tested with Cronbach's alpha, and the overall questionnaire structure was explored using principal axis analysis with oblimin rotation and extraction for factors with Eigen values >1.0. RESULTS: The adapted CAQ-B was validated in 96 patients (40 girls and 56 boys) with a mean age of 8.7 +/- 1.1 years (range 7-11). Most children had no difficulty understanding and completing the questionnaire. The median time taken to complete a questionnaire was 10 minutes. Internal consistency of the various scales ranged from 0.29 to 0.76 (Cronbach's alpha) when items were analysed according to the UK or Australian scale structure. This increased to 0.57-0.76 after item reduction. Physician-rated severity only correlated significantly with the Active Quality of Living (AQOL) domain (r = -0.29, p = 0.02). However, parent/caregiver-rated severity correlated with three of four patient-reported domains: AQOL (r = -0.359, p = 0.001), Passive Quality Of Living (PQOL) [r = -0.271, p < 0.01] and severity (r = 0.367, p < 0.001). The AQOL domain was significantly correlated with the PQOL domain (r = 0.513, p = 0.005). CONCLUSIONS: The children and parents/caregivers in this study found CAQ-B to be a simple and acceptable questionnaire with some evidence of content validity. While two of the domains did not meet internal consistency standards expected of HR-QOL instruments for adults (Cronbach's alpha = 0.70), they were acceptable for children of this age. The patterns of correlation also suggest that parent/caregivers' perception of the severity of a young child's asthma may be a better indicator of a child's HR-QOL than clinical diagnosis of severity. However, further investigation is recommended to improve and validate the internal structure of the scale.

The molecular epidemiology of HIV-1 in South and East Asia.

Foremost amongst human pathogens, the human immunodeficiency virus (HIV) exhibits a great genetic variability. The resultant fluidity of HIV enzymatic proteins allows them to remain functional whilst simultaneously evading immune surrveillance and antiretroviral therapy. This very variability, however, has been turned to powerful advantage in the study of the movement and evolution of HIV strains within and between human populations. Molecular analyses that estimate the relatedness between viral isolates, conducted in tandem with epidemiological studies, provide a new clarity of insight into the modes and routes of HIV transmission and epidemic spread. In this paper the principles underlying the molecular study of HIV and the achievements of this new field of epidemiology in southern and eastern Asia are reviewed.

Respect for the elderly in Asia: stability and change.

This study analyzes data from seventy-nine focus groups conducted in the Philippines, Singapore, Taiwan, and Thailand. The research examined ways in which respect for the elderly is experienced in these four countries, the extent to which respect has changed over time, and the reasons for changes in respect for the elderly. Using qualitative analysis, five distinct dimensions of respect were identified: gestures and manners, tokens, customs and rituals, asking for advice, and obedience. Focus group discussions indicated that changes have occurred on most of these dimensions of respect. The changes were attributed to variations in family structure and function, education, income, and modernization. These findings are discussed in relation to changing definitions of respect and variations in the way in which respect for the elderly is expressed in Asia.

Professional ideology and the construction of western psychiatry in Southeast Asia.

This article provides a critical examination of the professional ideology associated with the expansion of psychiatric treatment in the ASEAN countries of Southeast Asia. Four components of professional ideology are identified: appeal to "modernization"; medicalization of social problems; integration of psychiatry with primary health care; and panhuman uniformity of mental illness. However, the adoption of psychiatric technology has been a significant factor in the erosion of indigenous systems of social and psychological support since the colonial period. Contemporary psychiatric practices are also shown to exacerbate social inequalities, enhance state control of the populace, and continue to operate without adequate validation of diagnoses and treatments.

Participatory approaches to improving safety and health under trade union initiative--experiences of POSITIVE training program in Asia.

The participatory, action-oriented training program in occupational safety and health named POSITIVE (Participation-Oriented Safety Improvements by Trade Union InitiatiVE) was established in Pakistan and extended to other countries in Asia. The steps taken in the development of the POSITIVE program included collecting local good examples in safety and health, developing an action-checklist, testing a participatory training program, and conducting follow-up activities to examine local achievements. Training manuals were compiled to provide workers with the practical, easy-to-understand information on safety and health improvements and on the positive roles of trade unions. Trade union trainers trained in the methodology conducted serial POSITIVE training workshops in Pakistan and then in Bangladesh, Mongolia, Nepal, the Philippines and Thailand and recently in China. These workshops resulted in many low-cost improvements at the workplace level. These improvements were carried out in the technical areas of materials handling, workstations, machine safety, physical environment, and welfare facilities. The trade union networks have been vital in reaching an increasing number of grass-root workplaces and in expanding the program to other countries. This included the visits to Mongolia and Thailand of Pakistani trade union trainers to demonstrate the POSITIVE training. The participatory training tools used in the POSITIVE program such as the action checklist and group discussion methods were commonly applied in different local situations. Participatory approaches adopted in the POSITIVE program have proven useful for providing practical problem-solving measures based on the local trade union initiative.

Serum antibody responses to bacterial enteropathogens in Swedish travelers to south-east Asia.

The possibility that serological analysis may be more sensitive than bacteriological examinations of stool samples to detect enteric infections was evaluated in 80 Swedish travellers to South-East Asia. Serum and faecal specimens were collected before, during and after their travel. Serological analyses of pre-travel and any later serum specimen identified infection with enterotoxinogenic Escherichia coli (ETEC), Salmonella or Campylobacter jejuni in 28% of the travellers. The seroconversion rate was 72% in travellers excreting the homologous pathogen in their stool; all symptomatic cases and half of those who had an asymptomatic infection seroconverted. Bacteriological examinations of stool samples collected repeatedly during travel identified an enteropathogen in 20% of the travellers. However, the isolation rate decreased to 11%, when only a single routine faecal specimen was examined. Our findings suggest that serological analyses of pre- and post-travel specimens are sufficiently specific and may be at least as sensitive as conventional bacteriology to identify infections with bacterial enteropathogens in travellers. However, reliable serodiagnosis requires collection of pre-travel sera and might therefore only be useful in prospective studies of travellers' diarrhoea.

Hereditary disease as a cause of childhood blindness: regional variation. Results of blind school studies undertaken in countries of Latin America, Asia and Africa.

There is evidence from developed countries that genetic disease is the major cause of childhood blindness. Little data are available from most developing and newly industrialised countries concerning the relative importance of hereditary diseases as a cause of childhood blindness. Children in schools for the blind in 13 countries of Africa, Latin America and Asia were examined between 1990 and 1994 using a standardised method The anatomical site of abnormality and underlying aetiology were analysed for children with a corrected acuity in the better eye of less than 6/60 (severe visual impairment and blindness, svi/BL). In these countries II-39% of svi/BL was attributed to genetic disease. Genetic diseases were responsible for a higher proportion of childhood visual loss in countries with higher levels of socio-economic development. An autosomal recessive mode of inheritance was reported in 22-52% of children with genetic disease. Retinal dystrophies were the commonest form of genetic eye disease (49-80%) in all countries apart from Thailand and the Philippines where cataract was the commonest (43.9%). The role of consanguinity, and opportunities for further research are discussed.

Reduced fluoroquinolone susceptibility in Salmonella enterica serotypes in travelers returning from Southeast Asia.

During 1995 to 1999, we collected 1,210 Salmonella isolates; 629 were from Finnish travelers returning from abroad. These isolates were tested for susceptibility by determining MICs to ciprofloxacin, nalidixic acid, and seven additional antimicrobial agents. From 1995 to 1999, the annual proportion of reduced ciprofloxacin susceptibility (MIC > 0.125 microg/mL) among all travelers' isolates increased from 3.9% to 23.5% (p<0.001). The increasing trend was outstanding among the isolates from Southeast Asia; isolates from Thailand alone increased from 5.6% to 50.0% (p<0.001). The reduced fluoroquinolone susceptibility was nonclonal in character and significantly associated with multidrug resistance. A point mutation in the quinolone resistance-determining region of gyrA was present in all isolates with reduced susceptibility. These data provide further evidence for the rapid spread of multidrug-resistant pathogens from one continent to another.

Emerging viral diseases of Southeast Asia and the Western Pacific.

Over the past 6 years, a number of zoonotic and vectorborne viral diseases have emerged in Southeast Asia and the Western Pacific. Vectorborne disease agents discussed in this article include Japanese encephalitis, Barmah Forest, Ross River, and Chikungunya viruses. However, most emerging viruses have been zoonotic, with fruit bats, including flying fox species as the probable wildlife hosts, and these will be discussed as well. The first of these disease agents to emerge was Hendra virus, formerly called equine morbillivirus. This was followed by outbreaks caused by a rabies-related virus, Australian bat lyssavirus, and a virus associated with porcine stillbirths and malformations, Menangle virus. Nipah virus caused an outbreak of fatal pneumonia in pigs and encephalitis in humans in the Malay Peninsula. Most recently, Tioman virus has been isolated from flying foxes, but it has not yet been associated with animal or human disease. Of nonzoonotic viruses, the most important regionally have been enterovirus 71 and HIV.

Coltiviruses and seadornaviruses in North America, Europe, and Asia.

Coltiviruses are tickborne viruses of the genus Coltivirus. The type species, Colorado tick fever virus (from North America), has been isolated from patients with flulike syndromes, meningitis, encephalitis, and other severe complications. Another coltivirus, Eyach virus, has been isolated from ticks in France and Germany and incriminated in febrile illnesses and neurologic syndromes. Seadornaviruses are endemic in Southeast Asia, particularly Indonesia and China. The prototype virus of the genus, Banna virus (BAV), has been isolated from many mosquito species, humans with encephalitis, pigs, and cattle. Two other seadornaviruses, Kadipiro and Liao Ning, were isolated only from mosquitoes. The epidemiology of seadornaviruses remains poorly documented. Evidence suggests that BAV is responsible for encephalitis in humans. Infection with BAV may be underreported because it circulates in regions with a high incidence of Japanese encephalitis and could be misdiagnosed as this disease.

The biology and taxonomy of rust fungi associated with the neotropical vine Mikania micrantha, a major invasive weed in Asia.

Three microcyclic rust species were collected during surveys of the perennial asteraceous vine Mikania micrantha (Eupatorieae: Asteraceae) throughout its native range in the Neotropics but were absent in its invasive range in Asia. The commonest species, Puccinia spegazzinii with brown telioid telia, occurred wherever M. micrantha was found in South and Central America including the Caribbean island of Trinidad. Dietelia portoricensis, with occasional vestigial spermogonia and grayish-white to pale yellow columnar aecioid telia, was collected only in Costa Rica; while D. mesoamericana sp. nov., apparently restricted to Mesoamerica, can be distinguished by its abundant, yellowish-orange, fertile spermogonia, yellow to pale brown telial columns, larger teliospores, and 4-spored rather than 2-spored metabasidia. The fact that all three species share a fundamentally similar symptomatology suggests a common origin.

Persecution and martyrdom of nurses in selected regions of Asia during the period 1900-1978--Part 2.

The persecution and martyrdom of nurses identified in selected regions in Asia since the beginning of the twentieth century is discussed. Many missionary workers lost their lives in China during the Boxer rebellion in 1900. The persecution and martyrdom suffered by nurses working in China at the time is described followed by an account of the events which led to the deaths of nurses working in Korea, Thailand, Vietnam, Laos and East Pakistan during the early and latter half of the twentieth century.

Nutrition and health in South-East Asia.

Poor nutrition remains a significant contributor to morbidity and mortality in South-East Asia. Manifestations of this include protein-energy malnutrition, iodine deficiency diseases, vitamin A deficiency, iron deficiency and some non-communicable diseases of adults. The extent of these diseases, and their interactions with infection, make nutrition the single most important modifiable host factor underlying health status in the region. It is vital that long-term sustainable programs for the control of nutrition problems are accorded a high priority within the health sector.

HIV/AIDS in the transitional countries of Eastern Europe and Central Asia.

In the 1990s, HIV/AIDS became a major threat to health, economic stability and human development in countries in eastern Europe and central Asia. Social, political and economic transition exacerbated the structural conditions that allowed HIV/AIDS to flourish as dramatic changes led to increasing drug injection, economic decline and failing health and healthcare systems. There is a need to address the professional and ideological opposition - even in countries considered to be fully functioning democracies - to evidence-based public health interventions like harm reduction, coupled with treating HIV/AIDS for all those in need, if countries are to provide a more effective response.

Road traffic injuries in South Asia: national and organisational policy responses.

Increasing motorization leads to bleak projections for the future of road safety in many low- and middle-income countries. World Bank extrapolations suggest that between 2000 and 2020, road traffic deaths will decline by nearly 30% in high-income countries but will increase by upto 87% in low- and middle-income countries. The World report on road traffic injury prevention aims to raise awareness about the issue of road safety, and contribute to a shift in thinking about the nature of the problem of road traffic injury prevention, and appreciate the importance of road traffic injuries as a public health issue. South Asia currently faces an enormous challenge in this regard. However, Asian governments and stakeholders are now taking positive steps as they are aware that urgent action is needed. The responsibility for this problem needs to be shared among sectors, with public health taking an active role to end the carnage. The time for action is now. Partnerships and a systematic approach to this problem will save lives.

The millennium development goals and road traffic injuries: exploring the linkages in South Asia.

In a major summit of the members of the United Nations (UN) in 2000, a Millennium Declaration was adopted which called for making the elimination of poverty and promotion of sustainable development a global priority. A road map was agreed upon to operationalize the declaration, and the Millennium Development Goals (MDG) were integrated within the document. The MDGs are now increasingly being used to assess the performance of countries, institutions and the global community. WHO declares that the MDGs provide "a set of outcomes that are relevant to the development of national health policy frameworks". It also states that although MDGs do not cover all the components of public health, when broadly interpreted "the goals provide an opportunity to address important cross-cutting issues and key constraints to health". Consistent with WHO's call for a broad interpretation of the MDGs, and building on the health linkages identified by WHO, this paper explores the linkages between the MDGs and the impact of road traffic injuries (RTI). This is done in the context of South Asia, one of the poorest and populated regions of the developing world.
