National policy approaches to social care for elderly people in the United Kingdom and Singapore 1945-2002.

The authors compare policy approaches in the United Kingdom and Singapore on social care for older persons. The context of these approaches is discussed showing the development of policies, in each country from the aftermath of the Second World War to the present. Given that Singapore is a former British colony, it is of interest to scholars of social policy to examine its welfare approach as compared to the welfare state approach espoused by the United Kingdom. Both nations are faced with the challenges of an aging population, which necessitates handling similar problems with strategies that are in harmony with their respective economic, social, and cultural contexts. This paper considers their divergence of philosophies and policies, concluding with the recognition that the major difference lies in national and governmental expectations regarding the extent of the financial and regulatory responsibility for care for older people carried by the individual, the family, and the state.

Singapore experience in obesity surgery.

BACKGROUND: The outcome of bariatric surgery has been well documented in large series in the West. In Asia, where obesity has been less rampant, such surgery has been correspondingly less frequent, and there is a dearth of information on bariatric surgery on Asians. METHOD: The outcome of a personal series of 40 patients who underwent "gastric stapling" and banding from 1987 to 2003 in Singapore is analyzed. RESULTS: From 1987 to 1997, 26 patients underwent open bariatric surgery (Roux-en-Y gastric bypass 4, vertical banded gastroplasty 22). Initial mean BMI was 43.3 kg/m2. At 0.6, 1, 2, 4 and 8 years after surgery, mean BMI was 35.2, 31.9, 31.2, 31.1 and 34.1 kg/m2. Mean initial weight was 127.2 kg. %EWL was 42.2, 56.2, 56.9, 56.3 and 48.3%. From 1999 to 2003, 14 patients underwent adjustable gastric banding, 11 by laparoscopy. Initial mean BMI was 42.9 kg/m2. At 0.6, 1 and 2 years, mean BMI was 38.9, 36.6, and 32.6 kg/m2. Mean initial weight was 122.6 kg. %EWL was 26.6, 38.8 and 59.2%. One patient, following perigastric insertion of Lap-Band developed band slippage and gastric prolapse requiring removal. Since adopting the newer technique of combined pars flaccida and perigastric dissection in the last 6 patients, no band slippage has occurred. CONCLUSION: Our results of safety and low operative morbidity as well as the pattern and magnitude of weight loss following gastric stapling and banding for morbidly obese patients in Singapore appears to be similar to the Western experience.

Prevalence of ICA and GAD antibodies at initial presentation of type 1 diabetes mellitus in Singapore children.

OBJECTIVE: To determine the prevalence of islet cell antibodies (ICA) and antibodies to glutamic acid decarboxylase (GAD) in Asian children with diabetes mellitus (DM) at the time of diagnosis. PATIENTS AND METHODS: 41 children were studied at their initial presentation from 1993 to 2000. RESULTS: Mean age of onset (+/- SD) of DM was 7.6 (+/- 4.2) years. One or both of the two autoantibodies, ICA and anti-GAD, were present in 17 of the 41 children (41.5%) at the time of diagnosis. Comparing the group of children with autoantibodies and the group without detectable autoantibodies, there were no significant differences in body mass index (15.4 vs. 16.3 kg/m2), age of onset (7.4 vs. 7.8 years), random C-peptide levels (203 vs. 311 pmol/l), HbA1c levels (13.2 vs. 12.7%), and frequency of diabetic ketoacidosis at presentation (53.3 vs. 55%). CONCLUSION: Prevalence of antibodies at presentation of DM in Singapore (41.5%) is lower than in Caucasian populations (60-90%). Other autoantibodies yet to be identified may be contributory. Alternatively, non-immune mediated mechanisms may be responsible for a significant proportion of type 1 DM in Singapore children.

Epidemiology of 21-hydroxylase deficiency in Singapore.

We report the incidence and epidemiology of 21-hydroxylase deficiency in Singapore, based on a retrospective study of all known patients diagnosed with classical 21-hydroxylase deficiency in the past 21 years. The database was obtained from the case registry and questionnaire methodology, with 100% coverage of all practising pediatricians in Singapore. There were 42 patients affected with 21-hydroxylase deficiency in 964,558 live births over 21 years, comprising 64.3% salt wasters and 35.7% simple virilizers, of whom 50.0% were males and 50.0% females. The incidence of classical 21-hydroxylase deficiency is 4.5 per 100,000 live births, with a carrier frequency of 1:76, and a gene frequency of 0.0067. Although retrospective studies have inherent limitations, the gender and phenotype ratios suggest that the data provide a crude incidence level. This study underscores the necessity for prospective neonatal screening, so that the benefits of early diagnosis and treatment can be realized.

Biological monitoring of human exposure to environmental lead in Singapore.

An epidemiological survey was conducted in 1990-91 to determine the personal and environmental factors in Singapore which may affect blood lead levels. A total of 1,408 children and adults aged from 6 months to over 50 years were interviewed and their blood samples obtained for analysis using atomic absorption spectroscopy. Overall, the geometric mean blood lead level of the population surveyed was 76.6 micrograms/l. Multivariate analyses revealed that significant variations in blood lead concentrations were related, in decreasing order of importance, to: sex, age, active and passive smoking, exposure to traffic, and exposure to recent paintwork. The consumption of alcohol and traditional medicines were found not to be significant determinants. To reduce the environmental lead problem in Singapore, unleaded petrol has been introduced and control of lead additive in paints is being considered. The national anti-smoking programme should further contribute to an overall reduction in the blood lead level of the population.

HIV in Singapore--past, present, and future.

The first case of HIV infection in Singapore was reported in 1985. Between 1991 and 1998, the number of reported cases of HIV and AIDS increased rapidly before stabilizing from 1999. The epidemiology of the AIDS epidemic in Singapore is characterized by a predominance of male cases (seven to one) and heterosexual transmission. A multipronged control program comprising public education and education of high-risk groups, legislation, protection of the national blood supply, management of cases, and epidemiological surveillance has been put in place. The promotion of condom use among local sex workers has been fairly successful, with very low rates of HIV and other sexually transmitted infections (STIs). However, freelance and potential indirect sex workers such as masseuses and lounge hostesses are a concern in view of their higher prevalence of HIV and STIs. Another concern is the high proportion of cases who are diagnosed only when they develop AIDS. A better understanding of sexual networks among men who have sex with men will enable more effective intervention programs for this group. Fresh innovative approaches are needed to encourage safe sex practices and early screening.

The application of satellite remote sensing to coastal management in Singapore.

This paper reviews the application of satellite remote sensing to management of Singapore's coastal environment. Remotely sensed data have been used for marine habitat mapping, water quality monitoring, ship and ship-wake detection, oil spill detection, red tide monitoring, and mapping of reclamation activities. While these applications clearly cover most of the range of opportunities for use of remotely sensed data in the coastal zone, there is still a need for more complete baseline studies of natural resources and habitats, and monitoring of the impacts of development on the coastal and marine environment. There is also a requirement for more management-oriented research and continued development and revision of the available datasets. Integration and exchange of information between management agencies and research groups is also an important aspect of sustainable management of Singapore's coastal environment and marine resources.

Chinese proprietary medicine in Singapore: regulatory control of toxic heavy metals and undeclared drugs.

Traditional Chinese medicine (TCM) is gaining popularity as a form of complementary and alternative medicine. Reports of efficacy of TCM are increasing in numbers. TCM includes both crude Chinese medicinal materials (plants, animal parts and minerals) and Chinese proprietary medicine (CPM) [final dosage forms]. Despite the belief that CPM and herbal remedies are of natural origin, unlike Western medicine, and are hence safe and without many adverse effects, there have been numerous reports of adverse effects associated with herbal remedies. Factors affecting the safety of herbal medicines include intrinsic toxicity, adulteration, substitution, contamination, misidentification, lack of standardisation, incorrect preparation and/or dosage and inappropriate labelling and/or advertising. Hence, new regulations on the control of CPM were enforced in Singapore with effect from 1 September 1999. These include licensing and labelling requirements, as well as control of microbial contamination. This article also reviews reports of excessive toxic heavy metals and undeclared drugs in CPM in Singapore between 1990 and 1997. The names, uses, toxic heavy metal or drug detected and the year of detection are tabulated. Information on the brand or manufacturer's name are provided whenever available. The public and healthcare professionals should be better informed of the basic concept of TCM and its usefulness, as well as the potential adverse effects associated with its use. Greater control over the safety and quality of CPM could be achieved through good manufacturing practice, regulatory control, research, education, reporting usage of Chinese medicine (as in drug history) as well as reporting of adverse events.

Clinicopathologic study of odontogenic keratocysts in Singapore and Malaysia.

This was a retrospective study of odontogenic keratocysts in people from the Singapore-Malaysian region. The purpose of this study was to present the clinicopathologic features of odontogenic keratocysts in the Oriental population and to compare these data with those from other reported studies. Biopsy records from 1981 to 1992 of 61 cases of odontogenic keratocysts from patients in Malaysia and Singapore showed that 42.6% of patients were female and 57.4% of patients were male. Among patients with cysts, 75.4% were Chinese, 6.6% were Malays, 9.8% were Indians and 8.2% were other ethnic groups. The mean age of these patients was 26.98 +/- 15.38 years with a peak incidence occurring in the second to fourth decades. The location of the lesions was more often in the mandible (65.5%) than the maxilla (31.0%). There was a marked predilection for lesions to occur in the posterior mandible. Histologically, 90.2% of the cysts were lined with a para-keratinized stratified squamous epithelium while only 3.3% of the cysts were lined with orthokeratinized stratified squamous epithelium. Mixed para-keratinized and orthokeratinized epithelial linings were observed in 4 cases (6.5%). The cyst linings were mainly uninflamed (95.1%). Inflammation of the cyst wall was found in 42 cases (68.8%). Twelve (19.7%) cases contained keratin in the lumen. A satellite cyst was observed in only 6 cases (9.8%). In conclusion, most clinical and histological features seen in this study were similar to those found for Caucasians. The only clinical feature that was different was the peak age incidence, that ranged from the second to fourth decades, with an absence of a second peak. Odontogenic keratocysts presenting at the site of the dentigerous cyst were observed in 7 cases (11.5%).

Towards a unified program of rehabilitation for those with psychiatric disabilities in Singapore.

This paper sets out in detail how the Singapore Anglican Welfare Council (SAWC) has worked from its charter vision to a number of interlocking strategies and programs in the rehabilitation of those with psychiatric disabilities in Singapore. While the pathway toward a holistic and integrated model of rehabilitation may seem, in the body of this paper, to be almost rational-comprehensive in formulation, it has emerged from ongoing diagnosis and assessment of societal needs, and of the needs of those with psychiatric disabilities. It began simply from a compassionate vision but enlarged significantly as the writer continued in a doctor of business and administration program, to sharpen perceptions, purpose change within, and to collaborate with other agencies, both government and private. To facilitate the journey through this paper, the writer speaks of various continua of education and training, of growing the needed employment opportunities for the disabled, and of offering graduated housing and living skills opportunities. In reality, each initiative generated another and fed off one another. But the goal of all the activities described in this paper seems to have emerged as offering a graduated independence to those with psychiatric disabilities at their own choice and pace. They have taught the writer to listen, consult and to act in concert with them.

Beverage alcohol spending in Singapore: an empirical update.

Data on Singapore suggest strongly that consumer spending on imported and locally produced beverage alcohol was on the rise from 1986 through 1991 just as it had been from 1978 through 1986. Although not alarming in contrast to countries such as South Korea, the rise could signal an emerging problem with both public health and economic growth implications. In terms of economic growth, Singapore's continued economic success and its future plans require a highly skilled labor force, but skilled local workers are in very short supply. Continued rises in spending on beverage alcohol could pose a potential constraint to labor availability and therefore continued material progress. On the public health side, a rise in spending on beverage alcohol could lead to illness and accidents that cause chronic absenteeism, decrease on-the-job productivity, and lead to the permanent loss of valuable workers through alcohol-related motor car and other fatal accidents. A minimalist intervention strategy featuring education and rehabilitation might therefore be a reasonable policy option for government to consider pursuing, both on economic development and public health grounds.

Crisis prevention and management during SARS outbreak, Singapore.

We discuss crisis prevention and management during the first 3 months of the severe acute respiratory syndrome (SARS) outbreak in Singapore. Four public health issues were considered: prevention measures, self-health evaluation, SARS knowledge, and appraisal of crisis management. We conducted telephone interviews with a representative sample of 1,201 adults, > or = 21 years of age. We found that sex, age, and attitude (anxiety and perception of open communication with authorities) were associated with practicing preventive measures. Analysis of Singapore's outbreak improves our understanding of the social dimensions of infectious disease outbreaks.

Economics of neuraminidase inhibitor stock piling for pandemic influenza, Singapore.

We compared strategies for stock piling neuraminidase inhibitors to treat and prevent influenza in Singapore. Cost-benefit and cost-effectiveness analyses, with Monte Carlo simulations, were used to determine economic outcomes. A pandemic in a population of 4.2 million would result in an estimated 525-1,775 deaths, 10,700-38,600 hospitalization days, and economic costs of 0.7 dollars to 2.2 billion Singapore dollars. The treatment-only strategy had optimal economic benefits: stock piles of antiviral agents for 40% of the population would save an estimated 418 lives and 414 million dollars, at a cost of 52.6 million dollars per shelf-life cycle of the stock pile. Prophylaxis was economically beneficial in high-risk subpopulations, which account for 78% of deaths, and in pandemics in which the death rate was >0.6%. Prophylaxis for pandemics with a 5% case-fatality rate would save 50,000 lives and 81 billion dollars. These models can help policymakers weigh the options for pandemic planning.

Nurses' attitudes toward people with mental illnesses in a psychiatric hospital in Singapore.

A positive attitude toward people with mental illnesses is a necessary dimension of psychiatric nursing practice. Although studies have been conducted in Israel and Australia to examine the attitudes of nurses toward people with mental illnesses, no such study had been conducted in Singapore. This study explored the factors influencing nurses' attitudes toward and their involvement in caring for people with mental illnesses, and sought to establish the relevance and effects of mental health training on enhancing the nurses' positive attitudes. The study used a descriptive, self-administered questionnaire, which contained 24 statements scored on a Likert scale. Factors related to attitudes toward people with mental illnesses included age, professional qualification, years of psychiatric nursing experience, type of ward, and designation (i.e., position within the institution). The questionnaires were given to all of the local nurses working in a psychiatric hospital in Singapore, and 96% returned the questionnaires. Results showed that nurses with any of the following characteristics had a more positive attitude: age group of 31 to 50; professional qualification of advanced diploma in mental health nursing, nursing degree, or post-basic certificate; or more than 10 years of psychiatric nursing experience. In addition, nursing officers had a more positive attitude than staff nurses or assistant nurses, and nurses working in the short-stay wards had more positive attitudes than those working in the long-stay wards.

Stomach cancer incidence in a cohort of fishermen in Singapore.

A retrospective cohort study of 279 Chinese fishermen in Singapore was undertaken to examine the possibility of an elevated incidence of stomach cancer. The fishermen as a group had a greater than twofold excess in stomach cancer relative to Chinese men of similar age and over the same calendar years in Singapore, but the difference was not statistically significant. On further examination it was revealed that the four stomach cancer cases were observed among the subgroup of divers. The standardized incidence ratio for the divers was 4.3, which was significantly greater than unity. There was no evidence of an increased risk for cancer of any other site (lung, nasopharynx and liver) in this cohort. Dietary factors are suggested as a possible explanation for the observation of an increased risk for stomach cancer among fishermen, but larger studies are required to test this hypothesis.

Glaucoma pattern amongst the elderly Chinese in Singapore.

Glaucoma is a major blinding condition and is more prevalent amongst the elderly. A population study of 479 elderly Chinese aged 60 years and older, and residing in Singapore was carried out to determine the prevalence of glaucoma. The overall glaucoma prevalence was 4.8% with normal tension glaucoma (61%) and primary angle closure glaucoma (26%) being the most prevalent forms of glaucoma. All cases were silent in presentation with 97% of cases previously undiagnosed. With the greying population in Singapore, the issue of screening the elderly for glaucoma should be considered.

A randomized trial of the use of print material and personal contact to improve mammography uptake among screening non-attenders in Singapore.

The Singapore Breast Screening Project was a nationwide study inviting a random sample of women between the ages of 50 and 64 years for mammography at one of two hospital-based screening centres over two years. The current study was undertaken to determine if (1) mailed health educational material alone, or (2) the same material delivered during a home visit made to the subject and her family would increase the uptake among Singapore women who had not responded to two previous invitations for mammographic screening as part of the Project. This randomized trial employed a standard second reminder letter (R), the same letter packaged with health education material designed for the project (RP) and the addition of a home visit to make contact with the woman and her family (RV). The outcome measure of interest was the proportion of women in each group subsequently attending for screening. The study population comprised 1500 non-attenders whose names appeared consecutively in the database of the larger screening centre in this Project. These were randomized into three groups of 500 each. In total, they broadly resembled the national population in ethnic composition (72.3% Chinese, 17.8% Malays, 9.0% Indians and 0.8% Others). By the end of the project, 7.0% of women in group R and 7.6% in group RP responded to the invitation. In group RV, 428 homes were visited at least once and contact was made with the subject and her family member in 306 (71.5%) cases. Subsequently, 13.3% of the women visited attended for screening. The rate ratio for attendance in group RP compared with group R was 1.09 (95% CI 0.70 to 1.70) and for group RV compared with R, 1.90 (1.27 to 2.84). When analyzed by groups originally assigned to, women in group RV remained significantly more likely to attend than those in groups R or RP. The marginal cost of a home visit, based on this study, was $25.04 per additional woman screened. Our results suggest that the response to a second reminder is generally low and that additional print material does not improve screening attendance in this group of initial non-attenders. Personal contact with the family through a home visit appears to increase uptake, and may be helpful particularly among women who have less frequent contact with the health care system.

Stroke in Singapore--an overview.

Stroke is Singapore's third leading cause of death. The number of deaths and admissions to Singapore hospitals for stroke has been rising; when standardised for age, however, mortality rates for stroke for both genders have fallen. There has been a fall in the prevalence of hypertension, smoking and hyperlipidemia in the general population, with a rise in the prevalence of diabetes mellitus. The frequency of haemorrhagic stroke is higher than among Caucasian populations. While stroke patients tend to arrive to hospital early, the level of stroke awareness among stroke patients is poor. Inpatient and outpatient rehabilitation services are available. Many stroke patients are still disabled after their stroke. A national-level support group has been established. Over the years, the number of stroke victims and disabled stroke survivors will continue to rise. There is a need to persist with public education programs and risk factor screening, and to further develop hospital and community resources to meet this challenge.
