Underestimation of snakebite mortality by hospital statistics in the Monaragala District of Sri Lanka

Estimates of snakebite mortality are mostly based on hospital data, although these may considerably underestimate the problem. In order to determine the accuracy of hospital-based statistics, data on snakebite mortality in all hospitals in the Monaragala District of Sri Lanka were compared to data on snakebite as the certified cause of death for the district, for the 5-year period between 1999 and 2003. Data were cross-checked in a sample of hospitals and divisional secretariats within the district. Hospital statistics did not report 45 (62.5%) of the true number of snakebite deaths in the Monaragala District. Twenty-six (36.1%) of the victims either did not seek, or had no access to, a hospital. Another 19 (26.4%) had arrived at hospital, but had done so too late to receive treatment. Our study confirms the limitations of official hospital-based mortality data on snakebite.     

New dengue virus type 1 genotype in Colombo, Sri Lanka

The number of cases and severity of disease associated with dengue infection in Sri Lanka has been increasing since 1989, when the first epidemic of dengue hemorrhagic fever was recorded. We identified a new dengue virus 1 strain circulating in Sri Lanka that coincided with the 2009 dengue epidemic.     

An analysis of interneship training in Sri Lanka

The interneship period is a critical phase in the continuum of training provided to medical students. An analysis was made of the tasks the interne medical officers in Sri Lanka are engaged in during their period of training in different clinical disciplines. Data was collected by direct observations by trained observers for a continuous period of 10 days and self-reporting by the internes at the two teaching hospitals and four of the provincial hospitals where internes are posted. The reliability of the data was high. The results indicated the wide differences in the learning experiences of the internes in important aspects of patient care in the different training situations. The non-availability of any guidelines to the consultants with respect to the training intended is another deficiency. The study shows an urgent need to implement a planned and monitored interneship programme in the country.

Incidence of Physical Injuries in a Rural Community in Sri Lanka: Results of the First Community Survey in Sri Lanka

Background:

Injuries account for approximately 11% of all hospital admissions in Sri Lanka. However, no published data are available with regard to the community incidence of injuries in Sri Lanka.

Objectives:

To determine the community incidence of major intentional and unintentional physical injuries in a rural community in Sri Lanka.

Materials and Methods:

A rural community consisting of 225 families with 1029 inhabitants was studied. Data on major injuries for a period of one year were collected retrospectively.

Results:

There were 85 major injuries in the community during the year of study. This gives a major injury incidence of 82.6 per 1000 person years. This is three times the incidence based on hospital-derived data. Animal bites being the most common cause of injury was noted in 2.3% of the population followed by falls in 1.6%, contact with objects in 1.5%, cut injuries in 1% and road trauma in 1%.

Conclusions:

This study shows a higher incidence of major physical injuries (both intentional and unintentional) in the community than figures derived from hospital data. The prevention of injuries in a community such as the one studied here should be aimed at animal bites, falls, contacts with objects, cut injuries and road trauma.     

Knowledge, attitudes, and practices survey of rabies in a community in Sri Lanka

Objectives The primary objective of this study was to determine the level of knowledge, attitudes and practices (KAP) of rabies management and control of a sample population. The secondary objective was to compare the KAP with respect to rabies management and control between urban and rural areas and between pet and non-pet owners. Methods This cross-sectional study was carried out by conducting face-to-face interviews using structured questionnaires among 1570 respondents from selected households in the Kandy District, Sri Landa. Results Approximately 58% of the sample population was pet owners. Among all the respondents, there was a high level of awareness (90%) that dogs are the most common rabies reservoir, that the disease is fatal (79%), and that rabies can be prevented by vaccination (88%). Most of the subjects (96%) would seek treatment from a doctor or a hospital after being bitten by a dog. Although 76% of the respondents said that their pet dogs were vaccinated, only one-half were able to present a vaccination certificate upon request. The subjects from the urban areas would submit the head of an animal for rabies evaluation (69%) compared with those from the rural areas (57%). Pet owners (93%) are more aware that dog rabies vaccines are available from authorized offices than non-pet owners (87%). Conclusions The level of awareness of rabies and the level of receptiveness to rabies control measures are high. There is a difference in the attitudes and pet care practices relevant to rabies control between urban and rural areas. Pet owners tend to be more cooperative to rabies control activities. The attitudes and practices of the respondents may reflect the inaccessibility of facilities and the lack of services that would enable community participation in rabies control.     

Effects of Pollution on Health of Residents in an Industrial Area in Sri Lanka

The authors conducted a cross-sectional comparative prevalence study to evaluate the effect of pollution on individuals who lived in an industrial zone in Sri Lanka. In this study, 81 male and female children who were 1-12 yr of age and 158 adults (51 males, 107 females) in the industrial zone were matched with 73 children (32 males, 41 females) and 146 adults (58 males, 88 females), respectively, who lived in a nonindustrialized area and whose ages were similar to those of the exposed individuals. The authors used a pretested questionnaire and a detailed clinical examination, including peak expiratory flow rate measurements, to assess the prevalence of illness. Children in the industrial area were 2.3 times more likely to have unexplained episodic cough (95% confidence interval [Cl] = 0.98, 10.3) and 2.8 times more likely to have rhinitis (95% Cl = 1.1, 7.1). The adult population was 2.1 times more likely to have unexplained episodic cough (95% Cl = 1.13, 7.09), 3.7 times more likely to have unexplained headaches (95% Cl = 2.2, 6.3), and adults had a significantly greater reduction in expiratory flow (peak expiratory flow rate = 446 - 92x [industrial area] + 91 x [male] - 0.8x [years lived in the area]).     

Cognitive performance at school entry of children living in malaria-endemic areas of Sri Lanka

In a cross-sectional study, carried out in January 1997 at the beginning of the school year, the impact of repeated attacks of malarial infection on the cognitive performance of children at school entry in moderate malaria-endemic areas of Sri Lanka was investigated. The cognitive performance of 325 schoolchildren in grade 1 (mostly aged 5-6 years) in 2 districts of Sri Lanka which are endemic for malaria (Anuradhapura and Moneragala) was assessed by an entry performance test developed by the National Institute of Education, Sri Lanka. The indices assessed included writing, language and mathematical skills. There was no difference in any of the cognitive performance indices between children from Anuradhapura and Moneragala districts. The scores of most of the indices decreased as the number of malaria infections experienced by a child increased and the ability to identify letters was significantly impaired by the number of malaria infections a child had experienced after controlling for socio-economic and nutritional status. These findings suggests that repeated attacks of malaria in children can have an adverse impact on their development.     

Chronic kidney disease of unknown etiology in Sri Lanka

Introduction: In the last two decades, chronic kidney disease of unknown etiology (CKDu) has emerged as a significant contributor to the burden of chronic kidney disease (CKD) in rural Sri Lanka. It is characterized by the absence of identified causes for CKD. The prevalence of CKDu is 15.1–22.9% in some Sri Lankan districts, and previous research has found an association with farming occupations.

Methods: A systematic literature review in Pubmed, Embase, Scopus, and Lilacs databases identified 46 eligible peer-reviewed articles and one conference abstract.

Results: Geographical mapping indicates a relationship between CKDu and agricultural irrigation water sources. Health mapping studies, human biological studies, and environment-based studies have explored possible causative agents. Most studies focused on likely causative agents related to agricultural practices, geographical distribution based on the prevalence and incidence of CKDu, and contaminants identified in drinking water. Nonetheless, the link between agrochemicals or heavy metals and CKDu remains to be established. No definitive cause for CKDu has been identified.

Discussion: Evidence to date suggests that the disease is related to one or more environmental agents, however pinpointing a definite cause for CKDu is challenging. It is plausible that CKDu is multifactorial. No specific guidelines or recommendations exist for treatment of CKDu, and standard management protocols for CKD apply. Changes in agricultural practices, provision of safe drinking water, and occupational safety precautions are recommended by the World Health Organization.     

Cardiac complications of a dengue fever outbreak in Sri Lanka, 2005

A high incidence of cardiac complications was observed in an outbreak of dengue fever at General Hospital, Peradeniya, Sri Lanka, in 2005. This report describes 120 serologically confirmed dengue fever patients who presented during the outbreak. Seventy-five (62.5%) of these patients had electrocardiogram changes (T inversion, ST depression, bundle branch blocks) and were assigned to the 'cardiac group' (50 females, 25 males; median age 34 years, range 13-76). These patients were more susceptible to fatigue, dyspnoea, low peripheral oxygen saturation in room air (P=0.001), chest pain (P=0.001) and flushing of skin (P=0.05) than 45 (37.5%) patients who had normal electrocardiograms and made up the 'non-cardiac group'. In the cardiac group there were 31 primary and 44 secondary dengue patients. In the cardiac group, 17 (23%) patients had hypotension and 58 (77%) developed tachycardia and bradycardia (P<0.001) compared to four (9%) in the non-cardiac group, suggestive of significant cardiac dysfunction. There was no correlation between pulse rate and body temperature: cardiac group (r=0.05; P=0.63); non-cardiac group (r=0.11, P=0.46). RT-PCR detected DEN-3 in three cardiac patients.     

Prevalence of occupational injury and its contributing factors among rubber tappers in Galle,Sri Lanka

Background: Rubber tapping involves carrying heavy loads, navigating rough terrain, and using sharp tools. However, little is known about occupational injury among this vulnerable working population.

Objective: To assesses the prevalence, severity, and contributing factors associated with occupational injury among Sri Lankan rubber tappers and to identify possible interventions to improve occupational safety.

Methods: A questionnaire was administered to 300 Sri Lankan rubber tappers. The associations between tapper characteristics and injury within the last year were examined using log-binomial regression models. Short response answers were analyzed using qualitative content analysis.

Results: 300 tappers reported 594 injuries in the previous 12 months, and missed 1,080 days of work. The prevalence of one or more injuries was 49%. Factors associated with injury were being female, working an additional job, tapping with a two-handed approach, and depressive symptomology. Qualitative findings suggest three interventions to address injuries: (1) landscaping, (2) personal protective equipment, and (3) provision of eyeglasses.

Conclusions: Work-related injuries are common among Sri Lankan rubber tappers. These results highlight the importance of working with and including informal workers in the creation of Sri Lankan occupational health and safety regulations. We believe that the three interventions identified by respondents could help to reduce the risk of occupational injury among rubber tappers.     

Sri Lanka and the possibilities of achieving universal health coverage in a poor country

Sri Lanka has been lauded for providing good health coverage at a low cost despite having a modest per capita income. This article identifies the unique historical factors that enabled Sri Lanka to achieve near universal coverage, but it also discusses how this achievement is now being undermined by inadequate government investment in health services, the burdens of non-communicable diseases, and the growing privatisation of health services. In doing so, the article highlights the challenges of achieving and maintaining universal health coverage in a relatively low income country with a health system designed to treat infectious diseases and provide child and maternal health services as the country undergoes an epidemiological transition from infectious to non-communicable diseases. Using updated information on developments in the Sri Lankan health system, this article argues, in contrast with earlier publications, that Sri Lanka is no longer providing good health at a low cost. It shows that Sri Lanka’s low investment in health is detrimental and not an asset to achieving good health. The article also questions the possibilities of providing coverage for noncommunicable diseases at a low cost. The article has four main sections. The first details Sri Lanka’s accomplishments in moving toward universal health coverage. The second identifies the factors enabling Sri Lanka to do so. The third describes the equity and access challenges the health system now confronts. The fourth assesses what the Sri Lankan experience suggests about the requirements for universal health coverage when providing health services for treating non-communicable diseases becomes an important consideration.     

Career preferences of the 1984 medical graduates of Sri Lanka

A total of 196 graduates from the four medical schools in Sri Lanka responded to a postal questionnaire on their career preferences and factors influencing the choice of specialty. Medicine (38%), surgery (21%), paediatrics (15%) and obstetrics (12%) were the most popular choices. 'Service' specialties such as anaesthesia (1.5%), pathology (1.5%) and radiology (1%) were strikingly less attractive. Community medicine (2%) and general practice (2%) were similarly unattractive; medical administration (0.5%) was the least popular choice. In the choice of a career, opportunity for direct contact with patients (59%) was the most important determinant when compared to financial reward (12%), social prestige (10%) and fixed hours of work (12%). Research prospects (6%) and teaching opportunity (5%) were relatively unimportant considerations. The graduates preferred employment in the state health service (65%) to teaching in the clinical departments of medical schools (26%) and full-time private practice (7%). Pre- and paraclinical departments of medical schools attracted only 2% of the graduates. A total of 80% of the graduates wished to practise in the capital city or a major provincial city, while 10% chose to seek employment overseas. These results will be useful in planning undergraduate and postgraduate education, and in designing policies to attract manpower to the scarcity and high priority disciplines, so that the imbalances encountered would be minimal in the future.     

Short-term impact of an acute attack of malaria on the cognitive performance of schoolchildren living in a malaria-endemic area of Sri Lanka

A prospective study was conducted from January 1998 to November 1999 in a malaria-endemic area of Sri Lanka to determine the short-term impact of an acute attack of malaria on the cognitive performance of 648 schoolchildren attending grades 1 to 5 (mostly aged 6-11 years) in 4 schools. Three groups were studied comprising children with malaria, children with non-malarial fever, and healthy controls. Cognitive performance in language and mathematics at the time of presentation and 2 weeks later was assessed. At the time of presentation, children with malaria scored significantly less in both mathematics and language than children with non-malarial fever and healthy controls. Two weeks later, the mathematics and language scores of children with malaria improved but the scores were significantly lower than the scores of children with non-malarial fever (P < 0.001) and controls (P < 0.001). Having malaria was a significant predictor of cognitive performance after controlling for other confounding factors. These findings suggest that an acute attack of uncomplicated malaria causes significant short-term impairment of cognitive performance. The impairment persists for more than 2 weeks and appears to be cumulative with repeated attacks of malaria.     

Teaching of medical ethics in Sri Lanka

Medical ethics as taught by members of the Department of Forensic Medicine in three of five medical colleges in Sri Lanka is a 'rule ethic' ('normative ethic') based on 'traditional' or 'classical' ethics. Instruction includes the teaching of moral principles, illustrated with examples. Also included are aspects concerning the functions of the Sri Lanka Medical Council. The topic is evaluated in the essay, multiple choice question and oral components of the third MBBS (Part II) examination (end of fourth year). As presently taught the syllabus is thoroughly inadequate for dealing with modern (medical) ethical issues. The shortcomings and limitations in the present programme are pointed out and requisite improvements suggested. A case is made for an eclectic view of ethics, in which a 'situation ethic' would play a part. Finally, the training of a highly moral responsible medical professional is emphasized.     

Molecular epidemiology of human rabies viruses in Sri Lanka

Rabies is a lethal zoonotic disease caused by the rabies virus, which is transmitted by rabid animals to humans. Rabies is prevalent in all continents, with over 60% of human deaths occurring in Asia. Sri Lanka is a rabies-endemic country. This study shows that rabies afflicted more older individuals than children in Sri Lanka between 2008 and 2010. This novel finding indicates that older people in Sri Lanka should be more aware of the risk of rabies. Phylogenetic analyses of the rabies N and G genes showed that the Sri Lankan rabies viruses are distinct and probably originated from a single clone. The G–L noncoding region is highly diverse, and is suitable for the analysis of virus evolution within a country. A phylogenetic analysis of this region showed high diversity in the currently circulating Sri Lankan rabies viruses, which can be divided into seven clades. Some clades are unique to a specific geographic region, whereas others occur at multiple locations. This indicates that the movement of dogs, the main rabies-transmitting animal in Sri Lanka, is restricted in some areas but less limited in others. These data may help to formulate a more efficient rabies control program in Sri Lanka.     

A study of tuberculosis, malnutrition and gender in Sri Lanka

This study assesses the nutritional status of tuberculosis (TB) patients in Sri Lanka and differences in the nutritional presentation between males and females. In May-June 2002, cases from Colombo hospitals and controls from both the Sri Lankan Air Force Base and audience members at a 'better health' presentation in Colombo were assessed for nutritional status using a modified Standard Global Assessment. Fifty cases and 49 controls were recruited. Nutritional examinations revealed the cases to have significantly lower nutritional values than the controls (body mass index 16.2 vs. 24.0 kg/m(2); arm circumference 20.7 vs. 28.4 cm; muscle wasting [temple 56% vs. 0%; shoulder 46% vs. 0%]). The nutritional history revealed the cases to have higher levels of anorexia, vomiting, nausea and diarrhoea within the preceding fortnight. Differences between the genders were minimal other than an increase of 23 and 19% in the frequency of female cases having suffered with vomiting and nausea respectively. Consequently, both male and female TB patients in Sri Lanka are significantly malnourished. It is recommended that patients receive nutritional support during their treatment, with studies of the exact nutritional deficiencies at the micronutrient level and their effect on the immune system being required.
