    We have investigated the antinociceptive activity of zerumbone (1), a natural cyclic sesquiterpene isolated from Zingiber zerumbet Smith, in acetic acid-induced abdominal writhing test and hot plate test in mice. 1 given by intraperitoneal route produced significant dose-dependent antinociceptive effect in all the test models used. In addition, the antinociceptive effect of 1 in the hot plate test was reversed by the non-selective opioid receptor antagonist naloxone, suggesting that the opioid system is involved in its analgesic mechanism of action.

    The present study was carried out to evaluate the antinociceptive, anti-inflammatory and antipyretic effects of the aqueous extract of Solanum nigrum leaves using various animal models. The extract, at concentrations of 10, 50 and 100%, was prepared by soaking (1:20; w/v) air-dried powdered leaves (20 g) in distilled water (dH2O) for 72 h. The extract solutions were administered subcutaneously in mice/rats 30 min prior to the tests. The extract exhibited significant (P < 0.05) antinociceptive activity when assessed using the abdominal constriction, hot plate and formalin tests. The extract also produced significant (P < 0.05) anti-inflammatory and antipyretic activities when assessed using the carrageenan-induced paw edema and brewer's yeast-induced pyrexia tests, respectively. Overall, these activities occurred in a concentration-dependent manner, except for the 50% concentration of the extract, which was not effective in the abdominal constriction test. In conclusion, the present study demonstrated that S. nigrum leaves possessed antinociceptive, anti-inflammatory and antipyretic effects and thus supported traditional claims of its medicinal uses.

    We studied the effect of fentanyl pretreatment on alleviating pain during the injection of Propofol-Lipuro. One hundred and seventy patients were randomly allocated to receive either 100 mcg of intravenous fentanyl or normal saline (placebo) followed by intravenous Propofol-Lipuro premixed with 20 mg lignocaine. The incidence of injection pain was 32% and 13% in the placebo and fentanyl groups, respectively. We found a statistically significant reduction in incidence of injection pain in the fentanyl group when compared with the placebo group (p<0.003). The number needed to treat was 6 (3.2< 95% CI <15.1). In conclusion, fentanyl pretreatment is effective in alleviating pain during injection of Propofol-Lipuro.

    The aqueous extract of Ficus deltoidea leaves was evaluated for possible antinociceptive activity in three models of nociception, namely, acetic acid-induced abdominal writhing, formalin and hot plate test. The results of the present study showed that intraperitoneal administration of the F. deltoidea leaves aqueous extract at the dose of 1, 50 and 100 mg/kg, 30 min prior to pain induction produced significant dose-dependent antinociceptive effect in all the models used, which indicating the presence of both central and peripherally mediated activities. Furthermore, the antinociceptive effect of the extract in the formalin and hot plate test was reversed by the non-selective opioid receptor antagonist naloxone suggesting that the endogenous opioid system is involved in its analgesic mechanism of action. Thus, the present results demonstrated that F. deltoidea leaves aqueous extract contains pharmacologically active constituents which possess antinociceptive activity justifying its popular therapeutic use in treating conditions associated with the painful conditions.

    Anti-inflammatory and analgesic activities of a standardized Orthosiphon stamineus methanol:water (50:50 vol/vol) leaf extract (SEOS) were evaluated in animal models. Oral administration of SEOS at doses of 500 and 1,000 mg/kg significantly reduced the hind paw edema in rats at 3 and 5 hours after carrageenan administration (P < .01 and P < .01; P < .01 and P < .05, respectively). SEOS (1,000 mg/kg, p.o.) also produced significant (P < .05) analgesic activity in both the acetic acid-induced writhing test and the formalin-induced licking test (late phase) in mice and rats, respectively. However, SEOS showed no effect on the tail flick and hot plate tests in mice. The results of the present study support the proposal that O. stamineus has anti-inflammatory and non-narcotic analgesic activities. These findings justify the traditional use of the plant for treating pain and inflammation.

    BACKGROUND: Non-cardiac chest pain is an important disorder in Asia. The practice and views of gastroenterologists on non-cardiac chest pain in this region are not known.
    AIMS: To determine the current understanding, diagnostic practice and treatment strategies among gastroenterologists on the management of non-cardiac chest pain in Asia.
    METHODS: A 24-item questionnaire was sent to gastroenterologists in Mainland China, Hong Kong, Malaysia, Indonesia, Philippines, Singapore, Taiwan and Thailand.
    RESULTS: 186 gastroenterologists participated with a response rate of 74%. 98% of gastroenterologists managed patients with non-cardiac chest pain over the last 6 months. 64% felt that the number of non-cardiac chest pain patients was increasing and 85% believed that the most common cause of non-cardiac chest pain was GERD. 94% of the gastroenterologists believed that they should manage non-cardiac chest pain patients, but only 41% were comfortable in diagnosing non-cardiac chest pain. The average number of investigations performed was four in non-cardiac chest pain patients, and oesophago-gastro-duodenoscopy was the most commonly used initial test. A proton pump inhibitor was considered the first-line treatment in non-cardiac chest pain and was reported as the most effective treatment by the gastroenterologists.
    CONCLUSION: Most gastroenterologists were practicing evidence-based medicine, but frequent use of investigations and a lack of awareness of the role of visceral hypersensitivity in non-cardiac chest pain patients were noted.

    Post Arthroscopic intra-articular analgesia is a better method to avoid post-operative pain after arthroscopic surgery, thus avoiding the adverse effects of systemic analgesics. In this prospective randomized double blind study conducted on 90 patients, 30 patients in group A received 20 ml of intra-articular saline, 30 patients in Group B received 10 ml of intra-articular saline and 10 ml of 0.25% bupivacaine and 30 patients in Group C received 10 ml of 0.25% bupivacaine, 1 ml (30 mg) of ketorolac and 9 ml of saline intra-articularly. Ambulatory status, duration of analgesia and requirement for supplemented analgesia were compared in these three groups. Patients receiving this intra-articular analgesic combination of bupivacaine and ketorolac required significantly less supplemental postoperative analgesics. This combination significantly prolonged the duration of analgesia. Patients receiving this combination of drugs for intra-articular analgesia ambulated earlier.

    The aim of the study was to use data from an electronic medical record system (EMR) to look for factors that would help us diagnose acute myocardial infarction (AMI) with the ultimate aim of using these factors in a decision support system for chest pain. We extracted 887 records from the electronic medical record system (EMR) in Selayang Hospital, Malaysia. We cleaned the data, extracted 69 possible variables and performed univariate and multivariate analysis. From the univariate analysis we find that 22 variables are significantly associated with a diagnosis of AMI. However, multiple logistic regression reveals that only 9 of these 22 variables are significantly related to a diagnosis of AMI. Race (Indian), male sex, sudden onset of persistent crushing pain, associated sweating and a history of diabetes mellitus are significant predictors of AMI. Pain that is relieved by other means and history of heart disease on treatment are important predictors of a diagnosis other than AMI. The degree of accuracy is high at 80.5%. There are 13 factors that are significant in the univariate analysis but are not among the nine significant factors in the multivariate analysis. These are location of pain, associated palpitations, nausea and vomiting; pain relieved by rest, pain aggravated by posture, cough, inspiration and exertion; age more than 40, being a smoker and abnormal chest wall and face examination. We believe that these findings can have important applications in the design of an intelligent decision support system for use in medical care as the predictive capability can be further refined with the use of intelligent computational techniques.

    PURPOSE: Workstyle can be defined as an individual pattern of cognitions, behaviours and physiological reactivity that can occur while performing job tasks. Workstyle has been associated with the development of musculoskeletal disorders (MSDs) amongst office workers in developed countries. However, little is known about the contribution of workstyle on MSDs in developing countries such as Malaysia. The objective of this cross-sectional study was to examine the relationship between workstyle and musculoskeletal discomfort in a sample of office workers in Malaysia.

    METHODS: Office workers (N = 417; response rate 65.5 %) from four organisations completed a survey measuring physical and psychosocial hazards, job satisfaction, work-life balance, workstyle, and MSD discomfort levels. Hierarchical regression analyses were undertaken to examine predictors associated with self-reported musculoskeletal discomfort, and more specifically the relationship between workstyle and MSD discomfort.

    RESULTS: Musculoskeletal discomfort was significantly associated with working through pain, mental health, physical demands, gender and work-life balance (R (2) = 50.2, adjusted R (2) = 0.48; F (13, 324) = 25.09, p = 0.001). Working through pain is the strongest risk factor associated with MSD discomfort (ß = 0.49, p = 0.001) compared to other potential risk factors.

    CONCLUSIONS: Working through pain is influenced by work, social culture and religious beliefs. Workplace MSDs interventions that focus on the impact of physical and psychosocial hazards with emphasis on addressing adverse workstyles should take into account aspects related to work and social culture of the target population. Changes are recommended at both employee and management levels such as better communications and understanding concerning workplace problems with regards to minimizing MSDs at work.

    The study compared changes in blood biochemistry, hormonal and electroencephalographic indices associated with possible noxious stimuli following neck cut slaughter in conscious, non-anaesthetized versus minimally-anaesthetized goats. Ten male Boer crossbreed goats were assigned into two groups and subjected to either slaughter conscious without stunning (SWS) or slaughter following minimal anaesthesia (SMA). Hormonal responses and changes in electroencephalographic (EEG) parameters were not influenced by slaughter method. The SWS goats had higher glucose and lactate than did SMA goats. It can be concluded that the noxious stimulus from the neck cut is present in both conscious and minimally anaesthetized goats. The application of slaughter without stunning causes changes in the EEG activities that are consistent with the presence of post slaughter noxious sensory input associated with tissue damage and would be expected to be experienced as pain in goats.

    Noncardiac chest pain (NCCP) is common and has a significant impact on health care. Primary care physicians (PCPs)' attitudes, clinical approach, preference of diagnostic tests, referral patterns, and comfort in managing patients with NCCP in the Asia-Pacific region are not known. Consequently, we performed this survey in the Asia-Pacific region. The self-completed questionnaire was sent to PCPs in the Asia-Pacific region. A 28-item questionnaire contained questions on demographic information, characteristics of practice, preferences of diagnostic tests, referral patterns, treatment plans, and opinion on Helicobacter pylori and NCCP. A total of 108 (74%) PCPs returned the questionnaire. A mean of 18% of the patients were diagnosed with NCCP by PCPs in the past 6 months. Ninety-four percent of PCPs had treated NCCP patients in the last 6 months. Only 38% of the PCPs were comfortable in diagnosing NCCP but 85.2% believed that they should manage NCCP patients. PCPs in Malaysia and Philippines were more likely to refer patients to subspecialists. Fifty-seven and four-tenths percent of PCPs believed that H. pylori infection plays a role in the development of NCCP. The study demonstrates clearly that the understanding, diagnostic strategies, and treatment strategies of NCCP in the Asia-Pacific region are suboptimal and thus highlights the importance of educational and training programs tailored for PCPs in NCCP.

    BACKGROUND: Dienogest has been shown to substantially improve endometriosis-associated symptoms such as debilitating chronic pelvic pain, and in turn, health-related quality of life (HRQoL). To date, there is no data on patient-reported outcomes reflecting the real-world practice in Asia where endometriosis is a relevant health, social and economic burden. This non-interventional, multi-center, prospective study aims to investigate the influence of dienogest on HRQoL.

    METHODS: Asian women received dienogest (2 mg/daily) and were followed for 24 months. The effectiveness of dienogest to improve HRQoL and endometriosis-associated pelvic pain (EAPP) was assessed by patient-reported outcomes. HRQoL, especially the "pain" domain as primary endpoint, was evaluated with the Endometriosis Health Profile-30 (EHP-30) questionnaire. The numeric rating scale served to determine changes in the severity of EAPP. Within the presented interim analysis (data cut-off: 2017-11-27), the mean changes in EHP-30 and EAPP scores from baseline to 6 months upon availability of the data were evaluated. Treatment-emergent adverse events (TEAEs) and bleeding profiles were documented.

    RESULTS: Dienogest therapy decreased EHP-30 scores in all assessed domains (score 0-100, lower scores indicate better HRQoL). Primarily, the "pain" domain was improved in 78.4% of patients. EAPP was reduced (score 0-10, lower scores reflect less pain), highlighted by a mean reduction of the pain score by - 4.5 points. Patients with a higher EAPP score at baseline had an increased response to dienogest (- 6.2 points mean change) compared to patients with low baseline EAPP severity (- 1.4 points mean change). Both surgically and clinically diagnosed patients described comparable pain reduction, as well as women with or without prior treatment. Drug-related TEAEs were documented for 31.5% of patients, with amenorrhoea (5.9%) and metrorrhagia (5.1%) being the most common events. The bleeding pattern was changed upon dienogest, characterized by decreased normal bleeding (84.2 to 28.8%) and increased amenorrhea (3.2 to 42.9%) at 6 months.

    CONCLUSION: The data indicate an amelioration of HRQoL and EAPP upon dienogest therapy. No new safety signals were observed. Therefore, its use as first-line therapy for long-term management of debilitating and chronic endometriosis-associated pain represents an interesting option that remains to be further investigated.

    INTRODUCTION: This systematic review and meta-analysis aimed to assess whether machine-assisted agitation resulted in less postoperative pain (PP) compared with syringe irrigation with needle alone in adult patients undergoing root canal treatment.

    METHODS: A literature search was performed in 3 electronic databases for articles published before August 2018. Randomized clinical trials published in English that compared PP between machine-assisted agitation and syringe irrigation with needles as part of nonsurgical root canal treatment were included. Two authors were independently involved in the article selection process, data extraction, and assessment of the quality of included studies using the revised Cochrane risk of bias tool. The pooled effect estimates of the standardized mean difference (SMD) between machine-assisted agitation and syringe irrigation with needle was calculated by a random effects-modeled meta-analysis. A subgroup meta-analysis was performed. The quality of evidence was evaluated by the Grading of Recommendations, Assessment, Development and Evaluations approach.

    RESULTS: Six studies were included for systematic review. Meta-analysis was performed using 3 studies and showed that machine-assisted agitation resulted in less PP compared with syringe irrigation with needle at 24 hours (SMD = -0.73; 95% confidence interval, -1.04 to -0.42; I2 = 30.6%) and 48 hours (SMD = -0.60; 95% CI, -0.85 to -0.35; I2 = 0%). The quality of evidence by Grading of Recommendations, Assessment, Development and Evaluations for the PP outcomes (24 hours and 48 hours) was graded as "moderate" quality.

    CONCLUSIONS: Machine-assisted agitation reduced PP compared with syringe irrigation with needles in nonsurgical root canal treatment. Future clinical trials are needed to support the result of this review.

    The objective of the study is to determine the short- and long-term utility of the Chinese, Malay and English versions of the National Institutes of Health--Chronic Prostatitis Symptom Index (NIH-CPSI) in our ethnically diverse population. The NIH-CPSI was translated into Chinese and Malay, and then verified by back translation into English. Subjects included 100 new chronic prostatitis/chronic pelvic pain (CP/CPPS) patients, 71 new benign prostatic hyperplasia patients and 97 healthy individuals. Reliability was evaluated with test-retest reproducibility (TR) by calculating intraclass correlation coefficients (ICC). Internal consistency was evaluated by calculating Cronbach's alpha (alpha). Validity assessments included discriminant and construct validity. (Presented in the order of Chinese, Malay then English). ICC values for short-term (1 week) TR were 0.90, 0.80 and 0.89, while ICC values for long-term (14 weeks) TR were 0.54, 0.61 and 0.61. Cronbach's alpha values were 0.63, 0.62 and 0.57. The NIH-CPSI total score discriminated CP/CPPS patients (P<0.001) from the control groups with receiver operating curve values of 0.95, 0.98 and 0.94, respectively. Construct validity, reflected by the correlation coefficient values between the International Prostate Symptom Score and the NIH-CPSI of CP/CPPS patients were 0.72, 0.49 and 0.63 (all P<0.05). The Chinese, Malay and English versions of the NIH-CPSI each proved effective in our population. Short-term TR and discriminant validity were excellent for all three versions. However, long-term TR was only moderate, which might reflect variation in patients' perceptions of symptoms over time.

    INTRODUCTION: Chronic, nonspecific low back pain is a difficult ailment to treat and poses an economic burden in terms of medical expenses and productivity loss. The aim of this study was to determine the efficacy and safety of intramuscular metylcobalamin in the treatment of chronic nonspecific low back pain.
    METHODS: This was a double-blinded, randomised, controlled experimental study. 60 patients were assigned to either the methylcobalamin group or the placebo group. The former received intramuscular injections of 500 mcg parenteral methylcobalamin in 1 ml solution three times a week for two weeks, and the placebo group received 1 ml normal saline. Patients were assessed with Oswestry Disability Index questionnaire Version 2.0 and Visual Analogue Scale pain score. They were scored before commencement of the injections and at two months interval.
    RESULTS: Of the 60 patients, 27 received the placebo injections and 33 were given methylcobalamin injections. A total of 58 patients were available for review at two months (placebo: n is 26; methylcobalamin: n is 32). There was a significant improvement in the Oswestry Disability Index and Visual Analogue Scale pain scores in the methylcobalamin group as compared with the placebo group (p-value less than 0.05). Only minor adverse reactions such as pain and haematoma at the injection sites were reported by some patients.
    CONCLUSION: Intramuscular methylcobalamin is both an effective and safe method of treatment for patients with nonspecific low back pain, both singly or in combination with other forms of treatment.

    Effective cancer pain management is influenced by the attitudes and knowledge of treating physicians. A survey was conducted among the total population of government hospital doctors of Sarawak to study the barriers to cancer pain management. Two hundred and fifty-three respondents (83%) completed the survey. The study results highlight that knowledge about cancer pain management was low and barriers to morphine prescription were high. A majority of doctors were deterred from using morphine because of fear of addiction (36.5%) and respiratory depression (53.1%). Only 16.2% of the doctors chose the oral mode of administration to treat pain, furthermore 25% prescribed morphine on "PRN" basis. Doctors with undergraduate study in oncology consistently answered better suggesting that the situation can be improved by education. This study showed that barriers to morphine prescription and knowledge deficit amongst government doctors in Sarawak are strong but similar to those reported in western countries few years ago.

    Objective. To assess the nature and extent of rheumatic complaints in a semirural area in a multiracial (Malay, Indian, Chinese) community in Malaysia using the Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) protocol initiated by ILAR and the WHO.
    Methods. All members of a community of 2700 persons over the age of 15 years were offered a questionnaire based interview in Phase 1 of the study. Those with rheumatic complaints (pain in the last 1 week) were invited for a physical examination by a rheumatologist in Phase 2.
    Results. In total, 2594 (96%) persons agreed to a questionnaire based interview. Of those interviewed, 21.1% had a current rheumatic complaint. The pain rate was higher in women (23.8%) than in men (17.8%). Chinese men had the lowest age-standardized pain rate (9.9%), while Indian women had the highest rate (28.4%). In the study population, 14.4% complained of pain in the joints and/or musculoskeletal pain and 11.6% had low back pain. The knee was responsible for 64.8% of all complaints pertaining to the joints, and more than half those examined with knee pain had clinical evidence of osteoarthritis (OA). The complaint rate increased with age, up to 53.4% in the group age > 65 years. The major disability encountered was the inability to squat (3.1%). Fibromyalgia, soft tissue lesions, and localized OA of the knees were the main clinical diagnoses. Inflammatory arthritis was uncommon. Both Western and traditional sources of healthcare were used, often together. Self-medication was common (58.8%).
    Conclusion. Knee and back pain are the main rheumatic complaints in Malaysia, with complaint rates differing according to race and gender.
