PMID: 15689100

Studies have shown that smokers rationalize smoking by self-exempting beliefs. This study explored lay beliefs about smoking in Kelantan, Malaysia, using focus groups among outpatients, medical students and staff, and a questionnaire survey of 193 male smokers. In focus groups, patients said they could do something to make smoking safe. When asked, 'Do you think there are any safe ways to smoke?' 132/193 (68%) male smokers described at least one way. The commonest were 'drink water' (69/193, 36%), 'use a filter' (60/193, 31%), 'smoke after food' (27/193, 14%), and 'take sour fruit' (21/193, 11%). At three- or six-month follow-up, numbers agreeing with these beliefs were: for 'drink water' 67/115 (58%), for 'take sour fruit' 61/115 (53%), and for 'smoke after food' 38/115 (33%), with 88/115 (77%) supporting at least one. The main explanations for water were that it cleaned or moistened the lungs or throat. Sour fruit was described as cleaning, and sometimes as 'sharp', able to scrape out the essence of cigarettes. The conclusion is that self-exempting false beliefs about smoking are widespread, and here they probably represent an extension of the traditional humoral system. Anti-smoking campaigns and health workers in smoking cessation services should address these beliefs.

Fulltext Retrospective review of dot enzyme immunoassay test for typhoid fever in an endemic area

Typhoid fever remains a common problem in Malaysia, but for its diagnosis both blood culture and the Widal test have drawbacks. A dot enzyme immunoassay (EIA) has been developed which detects IgM and IgG antibodies to a specific 50 kDa outer membrane protein on Salmonella typhi. This study was performed among outpatients attending the university hospital in Kelantan, a state on the east coast of Peninsular Malaysia where typhoid is endemic. The dot EIA was done on 149 outpatients of all ages in whom typhoid was suspected. Of these, 60 were not analysable due to insufficient data. The other 89 were retrospectively classed as typhoid (total = 21), or not typhoid (total = 68). The criteria for diagnosis of typhoid was either, blood culture was positive, or with blood culture negative, temperature was at least 38 degrees C and Widal O and/or H titer greater than or equal to 1/160. We then compared the diagnosis with the EIA result. For the result where either IgM or IgG was positive, sensitivity was 90%, specificity 91% and negative predictive value 97%. For IgM positive, specificity was 100%. But the specificity of IgG positive alone was reduced by six false positives, which were probably due to persistence of IgG after acute infection. Other cases were found where IgG positive alone appeared in the first week of typhoid fever, probably due to rapid response in a second or subsequent infection. We also found that IgM-producing patients were significantly younger than those showing IgG alone positive.

Fulltext Beliefs and behavior of deceivers in a randomized, controlled trial of anti-smoking advice at a primary care clinic in Kelantan, Malaysia

Smoking deception is often ignored, but is important in health care. In this trial it was assessed at both study entry and outcome. At study entry, 1,044 males at a primary care clinic were asked smoking status and tested for breath carbon monoxide (CO). Of self-reported non-smokers, 57/402 (14%) were actually smokers, as were 59/251 (24%) of self-reported ex-smokers. The self-reported smokers (n=387) entered a randomized, controlled trial where the intervention comprised four questions on knowledge and beliefs about smoking, standardized verbal advice against smoking, and a leaflet. At follow-up, subjects were also questioned about beliefs. Follow-up was difficult, but 191/387 (49%) attended at three or six months. Of 27 who claimed to have quit, 6 (22%) were deceivers and 21 were confirmed quitters. Cessation did not differ between intervention and control groups. Overall confirmed cessation at six months was 16/387 (4.1 %). Confirmed quitters were significantly lighter smokers than deceivers and still smokers. There were non-significant trends between the outcome groups whereby deceivers had least knowledge and most lay beliefs, and quitters had most knowledge and fewest lay beliefs. The lay beliefs may prevent some smokers from quitting.

Fulltext Pitfalls in diagnosis and management of suspected urinary tract infection in an urban tropical primary care setting

Jackson AA, Lai PSM, Alias AM, Atiya N, Ramdzan SN, Abdul Malik TF, et al.

INTRODUCTION: Diagnosis and management of urinary tract infection (UTI) are complex, and do not always follow guidelines. The aim of this study was to determine adherence to the 2014 Malaysian Ministry of Health guidelines for managing suspected UTI in a Malaysian primary care setting.
METHODOLOGY: We retrospectively reviewed computerized medical records of adults with suspected UTI between July-December 2016. Excluded were consultations misclassified by the search engine, duplicated records of the same patient, consultations for follow-up of suspected UTI, patients who were pregnant, catheterised, or who had a renal transplant. Records were reviewed by two primary care physicians and a clinical microbiologist.
RESULTS: From 852 records, 366 consultations were a fresh episode of possible UTI. Most subjects were female (78.2%) with median age of 61.5 years. The major co-morbidities were hypertension (37.1%), prostatic enlargement in males (35.5%) and impaired renal function (31.1%). Symptoms were reported in 349 (95.4%) consultations. Antibiotics were prescribed in 307 (83.9%) consultations, which was appropriate in 227/307 (73.9%), where the subject had at least one symptom, and leucocytes were raised in urine full examination and microscopic examination (UFEME). In 73 (23.8%) consultations antibiotics were prescribed inappropriately, as the subjects were asymptomatic (14,4.6%), urine was clear (17,5.5%), or UFEME did not show raised leucocytes (42,13.7%). In 7 (2.3%) consultations appropriateness of antibiotics could not be determined as UFEME was not available.
CONCLUSION: Several pitfalls contributed to suboptimal adherence to guidelines for diagnosis and management of suspected UTI. This illustrates the complexity of managing suspected UTI in older subjects with multiple co-morbidities.
