How people perceive risk influences their behaviour towards these risks. We do not know how workers perceive risk of dying from diseases or accidents. This study was conducted among 198 workers of a security company in Malaysia. The workers were asked to score on a Likert scale of 1 to 5 the perceived risk of death of Malaysians from selected causes of death. The highest perceived risks of death were, in order of ranking, motor vehicle accidents, cancer and diabetes mellitus whereas according to the certified causes of death in Malaysia the highest risks of death among the selected items were cardiovascular disease, cancer and stroke. The difference in perception and mortality data needs be addressed.
Population norms for Health Related Quality of Life using SF-36 are described. A national sample was canvassed in 2000 using a self-administered SF-36 in Bahasa Malaysia and English. Response rate was 30.6%, with 3072 usable data. Male: Female ratio was 1.04 and mean age was 39.8 years. Quality of life was affected by age and sex. Older population and women had a poorer quality of life. Population norms for Malaysia differed from those of US, Canada and Australia. The malaysian general population norm described is useful as reference point for studies in Malaysia. Variability in scores by age and sex emphasize the need to use appropriate age- or sex-specific normative data.
This is a preliminary report on the use of the modified Airway Management Device in 50 spontaneously breathing patients undergoing elective day care surgery. We were successful in establishing a clear airway in all 50 patients, 46 of these patients had a patient airway on the first attempt. All patients were successfully managed with the Airway Management Device throughout the surgery. Partial airway obstruction during maintenance of anaesthesia occurred in three cases requiring only minor manipulations. Our result showed that the Airway Management Device may be used as an alternative airway management in anaesthesia.
This report describes inquiries relating to poisoning cases which were received by the National Poison Centre of Malaysia from the years 1996 to 2000. The study utilized data from the NPC report forms. Only data relating to patient contact with a poison or chemical were included in the analysis. The poison centre received an average of 186 poisoning inquiries per year. Doctors remained the highest group of caller to the poison centre throughout the five-year period. Nearly 50% of all inquiries was regarding pesticide poisoning and this trend remained constant during the five-year period. Overall, the findings showed that poisoning inquiries relating to patient care were lower than in Japan and the United States.
Between 1st January 1999 and 31st December 2000, 152 patients (156 eyes) with open-globe injuries were treated in the Department of Ophthalmology, Hospital Sultanah Aminah, Johor Bahru. The majority were male (88.2%), Malay (63.2%), from the Johor Bahru district (51.3%) and aged between 21 and 30 years (23.7%). Most injuries were workplace-related (41.4%). Lens injury, retinal detachment, endophthalmitis, intraocular foreign bodies and phthisis occurred in 40.4%, 15.4%, 14.7%, 12.2% and 11.5% of eyes respectively. A favourable visual outcome occurred in 55.4% of eyes. Prognostic factors for visual outcome include presenting visual acuity, relative afferent pupillary defect, wound location, lens injury, retinal detachment and endophthalmitis.
Antrochoanal polyps are a rare clinical entity. In this review of patients treated between January 1996 and September 2002, there were 18 cases of antrochoanal polyps. The mean age of patients was 20 years. Nasal obstruction was the most common symptom (17 cases, 94%), followed by rhinorrhoea (44%), epistaxis (33%), postnasal drip (28%), and snoring (22%). Chronic sinus was the most common associated rhinological finding (50%). Various surgical approaches were used: endoscopic polypectomy and middle meatal antrostomy in seven patients (38.9%), endoscopic polypectomy and inferior meatal antrostomy in three patients (16.7%) and Caldwell-Luc surgery in one patient (5.6%). No complications were noted in patients treated with powered instrumentation, including the three patients in whom combined transcanine approaches were used. We concluded that powered endoscopic polypectomy was safe and effective. It allowed a more complete dissection and may diminish the chance of recurrence.
Imperforate hymen is an uncommon obstructive anomaly of the female reproductive tract, which usually presents with intermittent and cyclical abdominal pain. Although it is usually sporadic, four cases of familial occurrence of imperforate hymen have been reported so far. Imperforate hymen is seldom associated with complications if it is detected early. In view of the possible familial occurrence, it is important to have a high index of suspicion in women who present with imperforate hymen. A detailed menstrual history of other female family members is necessary to enable early detection.
Knowledge of the position of the mental foramen is important both when administering regional anesthesia and performing periapical surgery in the mental region of the mandible. This study determines the position of the mental foramen in a selected Malay population. One hundred and sixty nine panoramic radiographs of Malay patients retrieved from a minor oral surgery waiting list were selected to identify the normal range for the position of the mental foramen. The foramen was not included in the study if there was any mandibular tooth missing between the lower left and right first molars (36-46). The findings indicated the most common position for the mental foramen was in line with the longitudinal axis of the second premolar (69.2%) followed by a location between the first and second premolar (19.6%). The right and left foramina were bilaterally symmetrical in three of six recorded positions in 67.7% patients. The mental foramen was most often in line with the second premolar.
