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 Lanka.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.
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.
Mortality following OP poisoning remains high despite adequate respiratory support, intensive care, and specific therapy with atropine and oximes. One-third of the subjects needing mechanical ventilation and reaching intensive care units die within the first 72 h of poisoning. Systolic blood pressure of less than 100 mmHg and the necessity of a FiO2>40% to maintain adequate oxygenation are predictors of poor outcome in patients mechanically ventilated in the ICU.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
