    Three hundred and fifteen female workers with at least three months' employment history in a factory manufacturing disk drives were studied. Each worker completed a self-administered questionnaire on their personal particulars, hours of work, opinion on the work and the workplace and the presence and severity of aches/pains experienced over the past one month. One hundred and forty one (44.8%) of the workers had complaints of aches/pains. Of these, 81 (57.5%) reported an improvement in their symptoms during their off-days. 59 (41.8%) had symptoms affecting two or more sites. The most commonly affected sites were the hands and shoulders, followed by the head and back. There was no significant difference in the prevalence of symptoms between workers from the different work stations. Ninety four (66.7%) of these workers reported that the pains that were severe enough to affect their activities. 76 (53.9%) had to seek some form of medical treatment while 33 (23.4%) had to be on medical leave. However, the physical examinations of this group of workers were normal. The symptoms appeared to be influenced by their attitude towards work. A significantly higher number of workers with symptoms expressed dissatisfaction with work and had complaints of a noisy and cold environment. The study showed that workers' morale and the quality of the work environment may play an important role in improving their general well-being.

    Emulsifiable concentrates of DursbanR (chlorpyrifos) and Dowco 214 (chlorpyrifos-methyl) were tested as mosquito larvicides using Hudson knapsack sprayers on small plots of rice-fields on Penang Island. The mosquitoes found in these rice-fields are predominantly Anopheles campestris and Culex tritaeniorhynchus. At dosages of 14, 28 and 56 gm hectare-1, Dursban is effective in maintaining the rice-fields free of Anopheles larvae for at least 2, 3 and 7 days respectively. Dowco 214 at 56 gm hectare-1 is able to keep the fields free of all mosquito larvae for at least 2 days.

    This study was conducted as part of the Human Exposure Assessment Location (HEAL) Project which comes under the United Nations Environment Programme/World Health Organisation (UNEP/WHO) Global environmental Monitoring System (GEMS). The objective of the study was to evaluate workers' exposure to lead in industries with the highest exposure. All subjects were interviewed about their occupational and smoking histories, the use of personal protective equipment and personal hygiene. The contribution of a dietary source of lead intake from specified foods known to contain lead locally and personal air sampling for lead were assessed. A total of 61 workers from two PVC compounding and 50 workers from two lead acid battery manufacturing plants were studied together with 111 matched controls. In the PVC compounding plants the mean lead-in-air level was 0.0357 mg/m3, with the highest levels occurring during the pouring and mixing operations. This was lower than the mean lead-in-air level of 0.0886 mg/m3 in the lead battery manufacturing plants where the highest exposure was in the loading of lead ingots into milling machines. Workers in lead battery manufacturing had significantly higher mean blood lead than the PVC workers (means, 32.51 and 23.91 mcg/100 ml respectively), but there was poor correlation with lead-in-air levels. Among the lead workers, the Malays had significantly higher blood lead levels than the Chinese (mean blood levels were 33.03 and 25.35 mcg/100 ml respectively) although there was no significant difference between the two ethnic groups in the control group. There were no significant differences between the exposed and control group in terms of dietary intake of specified local foods known to contain lead. However, Malays consumed significantly more fish than the Chinese did. There were no ethnic differences in the hours of overtime work, number of years of exposure, usage of gloves and respirators and smoking habits. Among the Malays, 94.3% eat with their hands compared with 9.2% of the Chinese. Workers who ate with bare hands at least once a week had higher blood lead levels after adjusting for lead-in-air levels (mean blood lead was 30.2 and 26.4 mcg/100 ml respectively). The study indicated that the higher blood lead levels observed in the Malay workers might have been due to their higher exposure and eating with bare hands.

    Post operative pain is an expected adverse outcome following surgery and it often delays mobilization and overall recovery. Acute post operative pain is subjective and cannot be measured directly. The objective of this study was to determine nurses’ knowledge and attitude towards post operative pain management. A cross sectional study was conducted in surgical wards and the Intensive Care Unit of Universiti Kebangsaan Malaysia Medical Centre from February to April 2008. A 28 item questionnaire which comprised of two domains: knowledge and attitude towards post operative pain management was used. Eighty four respondents successfully responded to the study. Twenty respondents (25%) possessed high level, 58 respondents (69%) possessed moderate level and 5 respondents (6%) had low knowledge level of post operative pain management. Positive attitude towards post operative pain management was reported by 66 respondents (78.5%). There was a significant relationship between nurses’ academic qualifications and attitude towards post operative pain management (χ² =29.96, p

    Surgical fixation of hip fractures in patients with below knee amputation is challenging due to the difficulty in obtaining optimal traction for reduction of the fracture. Surgeons may face difficulty in positioning such patients on the traction table due to the absence of the foot and distal lower limb. There are several techniques described to overcome this technical difficulty. In this case report, we present a case of a 64-year old gentleman with bilateral below knee amputation presenting with a comminuted right intertrochanteric fracture. We highlight a simple and effective method of applying skin traction to obtain adequate reduction for hip fracture fixation.

    BACKGROUND: Smoking has always been a huge problem in Malaysia and its surrounding nations. The purpose of this study was to determine the prevalence of cigarette smoking and to identify the influencing factors associated with smoking habits among adolescents.

    MATERIALS AND METHODS: This cross-sectional study was carried out on 226 respondents, using a questionnaire which had 4 sections: socio-demographic data, personal information, family information and social information. Data was analyzed using SPSS® version 16. For categorical variables, comparisons were made using Chi-square and for numerical variables a t-test was performed.

    RESULTS: The current smoker prevalence rate was 20.8% which showed a significant association between smoking and individual factors: level of knowledge on the effects of smoking (p < 0.05), significant association was seen between smoking and marital status of parents, smoking status of male siblings and various other aspects of the individuals themselves.

    CONCLUSIONS: Concerted efforts involving various parties should be taken to curb or prevent this problem or the number of teenage smokers in the country will increase. This in the long run will invite problems to the well being of the adolescents themselves, their families, community and the nation as a whole.

    Cement is a common cause of dermatitis. Workers affected are usually those in cement factories and at building construction sites. Cement dermatitis among port-workers is not so commonly reported. This paper describes an outbreak of dermatitis among stevodores at a port handling cement. The cement was imported in bags, and because of breakage, there was much spillage. It was also hot and dusty inside the hatch of the ship, and some of the stevodores worked bare-bodied. Cases of dermatitis began to appear in January 1983 and reached a peak in April 1983, gradually subsiding over the next few months to August 1983. This coincided with the increased tonnage of cement handled at the port. A total of 33 stevodores were reported as having dermatitis over this period. Of the 15 cases examined, 13 had eczema, and in 19 the hands and wrists were affected. However, most of the cases had multiple site involvement, including the arms, legs and abdomen.
    Samples of cement showed the presence of water-soluble chromium, varying from 9.9 to 17.8pg/g. As the stevodores were reluctant to go for skin patch-testing, only four were tested, but two did not return for the reading of the results. The other two were found to have a positive reaction to dichromates. The outbreak of dermatitis was probably due to several factors which are discussed.

    Catechin is astringent in taste, sparingly soluble in water and sensitive to oxygen, light and pH. These properties restrict its application in food products. The present study investigated the stability of inclusion complex (IC) and catechin in various food matrices and investigated in vitro recovery profile of catechin and IC in liquid, semi-solid and solid food matrices. Besides, the sensory profile of IC added yogurt was also determined. Results showed that IC and catechin was more stable in solid matrix compared to semi-solid and liquid matrices. IC added in milk and yogurt show the highest percentage recovery of catechin compared to IC added in cheese and catechin added in all the matrices in in vitro digestive system. Through IC, β-CD masked the bitterness of catechin. These results suggest that protection of antioxidant such as catechin by β-CD inclusion complex may have applications in functional foods and health supplements.

    INTRODUCTION: Shoulder injury related to vaccine administration (SIRVA) is a group of pathologies defined by pain and stiffness after intramuscular administration of vaccine to the upper arm and has been reported after COVID-19 vaccination. We aim to discuss its pathophysiology, clinical presentation, treatment and outcomes.

    MATERIALS AND METHODS: We retrospectively identified patients presenting with adhesive capsulitis within four weeks of administration of COVID-19 vaccine to the affected arm at our tertiary institution from March 2021 to December 2022.

    RESULT: Based on the above criteria, we identified seven cases of adhesive capsulitis, comprising one male and six female patients, with average age of 60 years. We present initial symptoms, signs and the duration from when the vaccine was administered. We have highlighted our treatment strategies as well as the clinical and functional outcomes reported by these patients after treatment. We have reported improvement in both Visual Analogue Scale (VAS) and range of motion (ROM) in all our patients after non-surgical management which included physiotherapy and, in some cases, hydrodilatation.

    CONCLUSION: SIRVA related adhesive capsulitis is rare and under-reported with limited information in current literature. This study highlights that adhesive capsulitis is a potential complication arising from improper COVID-19 vaccine administration and reinforces traditional wisdom of administering vaccinations on the non-dominant arm. Conservative treatment strategies appear to be effective, particularly hydrodilatation combined with physiotherapy, and patients are expected to have a good return of function.

    AIMS: The objective of the study was to examine the quality of life amongst the end stage renal disease (ESRD) haemodialysis patients in Malaysia.

    MATERIALS AND METHODS: A cross sectional descriptive study was conducted on 72 ESRD patients at a Dialysis Centre in Malaysia. The modified KDQOL-SF™ subscales, kidney disease-targeted scale and 36 item health survey scale questionnaires were used.

    RESULTS: The overall health rating was 66.73 ± 11.670 indicating good quality of life. There was no significant difference between quality of life for the different domains according to gender (p >0.05). However, there were significant differences between quality of life in the domain of burden of kidney disease. Physical functioning deteriorated significantly with age (p=0.012) while social functioning was lowest in the 50-65 years age group (p=0.037). Those who had no morbidities had significantly better scores on the effects of kidney (p=0.036), burden of kidney disease (p=0.011) and physical functioning (p=0.025).

    CONCLUSIONS: Patients undergoing haemodialysis have been found to have good quality of life despite having ESRD. It is therefore of paramount importance to constantly monitor the standard of care for these patients to enable them to live their life to the fullest.

    BACKGROUND AND AIMS: Nurses play a pivotal role in pain management. Unrelieved pain significantly interferes with patient's quality of life and is of great concern to nurses. The aim of this study was to determine the knowledge level and attitudes of nurses related to pain management.
    MATERIALS AND METHODS: This descriptive study was conducted in an urban hospital. A total of 84 registered nurses were recruited using a modified version of questionnaire of Knowledge and Attitudes Survey Regarding Pain.
    RESULTS: The findings showed that respondents possessed good knowledge (99.12±14.810) and attitude (66.00 ±10.415) towards pain management. Fifty five respondents (66%) responded as positive to cultural beliefs affecting their pain management and 65 respondents (77%) viewed that their personal experiences had influenced their practice in pain management. Another 45 respondents (54%) reported they have attended pain course. There was no significant difference in pain management between respondents' year of service, cultural belief and personal experiences (p=>0.05). In terms of knowledge towards to pain management, respondents' age groups of more than 40 years were noted to possess better knowledge (p=0.046), unmarried respondents (p=0.018), and attended pain course (p=0.001) were significant. Attitude towards to pain management was not significant (p≤0.05).
    CONCLUSION: Nurses' knowledge and attitudes scores were impressive but there is room for further improvement to pain management. Continuing education organized by the hospital had significant impact on the nurses. However, this education course has to be reinforced from time to time in order to improve patients' pain experiences.

    BACKGROUND AND AIMS. The experience in intensive care unit (ICU) has created an intense emotional situation both to patients and their family members. The aim of this study was to determine the family members information needs of critically ill patients in ICU.

    MATERIALS AND METHODS:
    A descriptive cross-sectional study was conducted on 200 family members of patients admitted in ICU. A face to face interview was conducted and a self-report questionnaire of the Critical Care Family Needs Inventory (CCFNI) was used.

    RESULTS:
    Findings reported CCFNI five sub-attributes that ranked from highest to lowest included: support (mean 39.13 ± 6.189); proximity (mean 27.17 ± 3.384); information (mean 24.25 ± 3.093); assurance (mean 22.67 ± 1.862) and comfort (mean 16.24 ± 2.776). There were no significant differences in needs between family members with different gender (p >0.05). However, there were significant differences in support needs between family members with admission to ICU with (t=-2.111; p <0.05). There were significant differences in assurance needs (F=3.542; p <0.05) and information needs (F=3.681; p <0.05) between family members with age. There were no significant differences in needs between family members with different education level (p >0.05) whereas assurance needs were significant differences with education level of (F=3.542; p <0.05).

    CONCLUSION:
    The results suggest that family members perceived support and proximity as the most crucial need. Comfort need was viewed as least important. Although this study was conducted in a tertiary hospital, the findings could still provide insight for nurses to improve the delivery of care to patients and family members.

    Antimicrobial resistance to the extended-spectrum cephalosporins is increasingly reported worldwide. In the local setting, nosocomial infections with multi-resistant Gram-negative bacilli are not uncommon and are a growing concern. However, there is limited data on the carriage rates of such organisms in the local setting. In May 2001, a prospective study was carried out to determine the enteric carriage rates of ceftazidime-resistant Gram negative bacilli (CAZ-R GNB) among residents of nursing homes and from in-patients of the geriatric and adult haematology wards of University Malaya Medical Centre. Ceftazidime-resistant Gram-negative bacilli (CAZ-R GNB) were detected in 25 samples (30%), out of which 6 were from nursing home residents, 5 from geriatric in-patients and 14 from the haematology unit. A total of 28 CAZ-R GNB were isolated and Escherichia coli (10) and Klebsiella pneumoniae (7) were the predominant organisms. Resistance to ceftazidime in E. coli and Klebsiella was mediated by extended-spectrum beta-lactamases (ESBLs). Although the majority of the CAZ-R GNB were from patients in the haematology ward, the six nursing home residents with CAZ-R GNB were enteric carriers of ESBL-producing coliforms. Prior exposure to antibiotics was associated with carriage of ESBL organisms and to a lesser extent, the presence of urinary catheters.

    BACKGROUND AND OBJECTIVE: Physical and behavioural problems from extended usage of electronic devices are issues among primary school children. This study is aimed to investigate the prevalence of physical and behavioural complaints arising from the electronic device usage and to identify the potential factors that predicted the complaints.

    METHODS: This was a primary school-based cross-sectional study using multistage cluster sampling, conducted at Bau district in Sarawak, Malaysia in 40 primary schools. A questionnaire was used to collect information of usage pattern in insufficient lighting, timing and position. The physical and behavioural complaints were traced. Data analysis was performed using SPSS version 22. A p-value < 0.05 with 95% CI was considered as statistically significant.

    RESULTS: About 52.8% of the 569 students used digital devices in a bright room, 69.8% in the day time and 54.4% in sitting position. The physical complaints were headache (32.9%), neck, shoulder and back pain (32.9%) followed by by eye strain (31.8%). Regarding behavioural problems, 25.7% of the students had loss of interest in study and outdoor activities (20.7%), skipped meals (19.0%) and arguments/disagreements with parents (17.9%). After logistic regression analysis, the lying position (OR=1.71, 95% CI: 1.096, 2.688) and darkroom lighting (OR=2.323 95% CI: 1.138, 4.744) appeared to be potential predictors of the complaint.

    CONCLUSION: One-quarter of the students studied experienced physical complaints, and one-fifth had behavioural problems associated with the use of electronic devices. Lying position and darkroom lighting are the potential predictors of complaints. Therefore, we suggest that the children should use electronic devices in the sitting position with adequate room lighting.

    The aim of this work was to recover the cellulose fibers from EFB using low-transition-temperature-mixtures (LTTMs) as a green delignification approach. The hydrogen bonding of LTTMs observed in 1H NMR tends to disrupt the three-dimensional structure of lignin and further remove the lignin from EFB. Delignification process of EFB strands and EFB powder were performed using standard l-malic acid and cactus malic acid-LTTMs. The recovered cactus malic acid-LTTMs showed higher glucose concentration of 8.07 mg/mL than the recovered l-malic acid LTTMs (4.15 mg/mL). This implies that cactus malic acid-LTTMs had higher delignification efficiency which led to higher amount of cellulose hydrolyzed into glucose. The cactus malic acid-LTTMs-delignified EFB was the most feasible fibers for making paper due to its lowest kappa number of 69.84. The LTTMs-delignified EFB has great potential to be used for making specialty papers in pulp and paper industry.
