the health services of sri lanka present and future.1) sri lanka has achieved a high human development status; 2) the health sector, and particularly the government health sector, has played an important role in this achievement. 3) the health transition is going to increase the burden of disease and the demand for health services; 4) the government health services have been underfunded and the provincial health services have been more underfunded; 5) the most cost efficient health services, anywhere in the world, are government funded; 6) theref ...19958536324
common origin of human t-lymphotropic virus type-i from iran, kuwait, israel, and la réunion island.we found previously that kuwaiti htlv-i isolates had two nucleotide substitutions in the most frequently sequenced regions of htlv-i genome, namely: t-->c 4783 in the pol and t-->c 6569 the env genes. these substitutions were observed rarely in other htlv-i isolates and seemed to be good markers of the htlv-i lineage, the "epicentre" of which was located in mashhad, iran. to test this hypothesis we sequenced the fragments of htlv-i genome including sites 4783 and 6569 from seven isolates obtaine ...19979131461
influence of iron, growth temperature and plasmids on siderophore production in aeromonas hydrophila.aeromonas hydrophila strains obtained from diarrhoeal samples of human patients (19 isolates) and freshwater ponds (11 isolates) were analysed for siderophore production. both clinical and environmental isolates showed significantly increased siderophore production under iron-limiting conditions both at 28 degrees c and at 37 degrees c. clinical isolates consistently produced higher levels of siderophores than did the environmental isolates. the role of plasmids in moderating siderophore product ...19979364139
[current aspects of extrauterine pregnancy in nosy be (madagascar), from november 1993 to february 1995].we present the current aspects of ectopic pregnancies in nosy be, madagascar, and possible solutions. ectopic pregnancies are problems of public health here as in many developing countries. nosy be is a small island northwest of madagascar and is part of madagascar's territory. this was a prospective, continuous, nonrandom, open study of 27 ectopic pregnancies observed on this island; all were confirmed by laparotomy during 16 months from november 1993 to february 1995 in the department of gener ...19979172872
plague, a reemerging disease in madagascar.human cases of plague, which had virtually disappeared in madagascar after the 1930s, reappeared in 1990 with more than 200 confirmed or presumptive cases reported each year since. in the port of mahajanga, plague has been reintroduced, and epidemics occur every year. in antananarivo, the capital, the number of new cases has increased, and many rodents are infected with yersinia pestis. despite surveillance for the sensitivity of y. pestis and fleas to drugs and insecticides and control measures ...19989452403
[the development of public health education: the mauritius experience].a public course has been initiated in 1990 in mauritius for covering the national growing needs of public health specialists. this training course was organized jointly by the ministry of health, the university of bordeaux ii and the french cooperation. after 3 sessions dedicated specifically to the mauritian physicians, the course has been re-designed for the needs of the other countries of the region. a feasibility study performed in 1994 in the countries of the indian ocean region showed that ...19979172876

[malaria in mayotte: past, present and future].discovered as a form of intermittent fevers in 1852 and confirmed by blin in 1905, malaria has had a large impact on the mortality and the morbidity of the population living in mayotte until 1976. an evolutionary analysis of the disease shows two distinct periods. the first period between 1792 and 1974 concerns the date of introduction of malaria to the island and the limited actions of the fight against malaria led by different organizations. the second period from 1976, when the program was es ...19958784540
intra-household allocation of food and health care: current findings and understandings--introduction.this work offers an anthropological analysis of intra-household processes underlying gender- and age-specific differences in individual nutritional and health care allocations and outcomes in particular cultures. based on recent ethnographic studies in india, nepal, madagascar, mexico, and peru, correspondences are analyzed between local cultural ("emic") and scientist-policy maker practitioner ("etic") understandings of nutrition, health, and human development, and the relative "values" of fema ...19979178411
[vector control in the epidemics of the madagascar highlands].the plateau, or more precisely the highlands, cover most of the central part of madagascar with an altitude higher than 1,000 m. there the climate is tropical with a wet and hot season, from october through april coincident with further outbreaks of malaria. this alternates with a dry season from may through september when the temperature is not favorable to the development of the vectors and the extrinsic cycle of the parasite. the malaria is unstable. the short season of transmission is someti ...19958784547
[human diseases transmitted by culicidae in southwest indian ocean islands].south-west indian ocean islands were inhabited at the beginning and free from all kind of vector. in madagascar, mayotte, moheli and anjouan, malaria vectors were carried by the first settlements. according to epidemics, the anopheles arrived in 1867 in mauritius, 1869 in la reunion and 1920 in grande comore. rodrigues, saint-brandon and the seychelles are still free from malaria vectors in the coastal part of madagascarcar and in comores archipelago, malaria is stable with a permanent transmiss ...19989559180
[entomological surveillance in mauritius].the entomological surveillance is an essential link in the fight against malaria in mauritius. because of the large number of malaria-infected travellers in mauritius and the presence of the vector anopheles arabiensis, the risk of local transmission is very real. the medical entomology division together with the malaria control unit and the health appointees exert a rigorous entomological surveillance of malaria. field agents make entomological investigations of pilot villages and around the ha ...19958784549
epidemiology of end-stage renal failure in reunion island (results from the registry of the indian ocean society of nephrology).end-stage renal disease (esrd) on long-term dialysis is a substantial problem in reunion because of the high incidence and prevalence of this disease due to non-insulin-dependent diabetes mellitus (niddm) and systemic arterial hypertension.19989623542
organophosphorus insecticide poisoning.organophosphorus insecticides (opi) are the commonest cause of poisoning in sri lanka. being inhibitors of esterases, opi cause an acute cholinergic crisis as the initial phase of neurotoxicity. the intermediate syndrome (ims) which develops 24 to 96 hours after poisoning, and the delayed polyneuropathy (opidp) which manifests several weeks later, suggest a triphasic effect of op intoxication. opi may also cause extrapyramidal manifestations. chronic neurobehavioural effects of longterm exposure ...19989624840
[malaria: research perspectives in medical entomology in madagascar].the entomological studies on malaria in madagascar had especially concerned the behavior of vectors in relation to insecticides. the cessation of spraying within the homes and the absence of chloroquine allowed a re-emergence of malaria on the plateau in the 1980's. this phenomenon pointed out the heterogeneity of the transmission on the island. it was necessary to define the entomological characteristics of the four principal facies of transmission in madagascar. these studies provided the serv ...19958784550
evolution of malaria in africa for the past 40 years: impact of climatic and human factors.different malarial situations in africa within the past 40 years are discussed in order to evaluate the impact of climatic and human factors on the disease. north of the equator, more droughts and lower rainfall have been recorded since 1972; and in eastern and southern africa, there have been alternating dry and wet periods in relation to el niño. since 1955, the increase in human population from 125 to 450 million has resulted in both expansion of land cultivation and urbanization. in stable m ...19989673911

serologic evidence for an epizootic dengue virus infecting toque macaques (macaca sinica) at polonnaruwa, sri lanka.dengue is one of the most rapidly emerging diseases in the tropics. humans are the principal reservoir of dengue viruses. it is unclear if nonhuman primates also serve as a reservoir of human dengue viruses under certain conditions. in this study, a cross-sectional serologic survey was carried out to characterize the pattern of transmission of a recently identified dengue virus among toque macaques in sri lanka. the results indicated that an epizootic dengue virus was active among the macaques. ...199910072155
maternal exposure to influenza and cold in pregnancy and electrodermal activity in offspring: the mauritius study.data are in conflict concerning whether a mother's exposure to influenza in pregnancy gives rise to an increased probability that her offspring will develop schizophrenia. in northern hemisphere studies, exposure to influenza and cold tend to be confounded. the present study, carried out in mauritius, examines the effect of maternal exposure to the virus and separately to cold on aspects of electrodermal activity that have been shown in other studies to be related to schizophrenia. the findings ...19979260495
health care auxiliaries in the detection and prevention of oral cancer.oral cancer is one among the few human cancers with a vast potential for prevention. one of the operational strategies considered to translate preventive measures into practice in developing countries has been the use of community health workers and other health auxiliaries of the primary health care system to disseminate anti-tobacco health education messages and to provide mouth examinations in high-risk individuals during their routine home visits and community meetings. studies conducted in ...19979307722
[seroepidemiologic study of human plague in madagascar].an igg anti-f1 enzyme linked immunosorbent assay (elisa) has been developed for plague diagnosis in the malagasy republic. the sensitivity of the test was 91.4% and the specificity 98.5%. this technique is cheap and the cross reaction with other infections diseases prevalent in madagascar is very limited. during the urban plague outbreak (mahajanga city, 1995), the positive predictive value and the negative predictive value were 95.2% and 97% respectively. during this outbreak, the usefulness of ...19979309233
effects of prenatal methylmercury exposure from a high fish diet on developmental milestones in the seychelles child development study.mercury is widespread in the environment and exists in several physical and chemical forms. prenatal exposure to methylmercury disrupts brain development. the most common mode of prenatal methylmercury exposure is maternal fish consumption. studies of human prenatal exposure in iraq following maternal ingestion of methylmercury treated grain suggested that maternal hair mercury concentrations above 10 ppm may be related to delayed developmental milestones and neurological abnormalities. this lev ...19979339828
an analysis of autopsy brain tissue from infants prenatally exposed to methymercury.brains from 32 neonatal autopsies from the seychelles were examined histologically and analyzed for mercury levels. six brain regions were sampled: frontal and occipital cortex, temporal cortex with hippocampus, basal ganglia with thalamus, cerebellum, and pons with medulla. tissue blocks for histology and mercury analysis were taken from opposing faces to provide for correlation of findings. similar studies were performed on 12 reference neonatal brains from rochester, new york. no clear-cut de ...19958714873
