    BACKGROUND: Acute pain assessment in the emergency department (ED) is important in particular during the triage process. Early pain assessment and management improve outcome. The objective of this study was to determine the effects of documentation and display of patient's self-assessment of pain using numerical rating scale (NRS) on analgesic use among adult trauma patients in ED.
    METHODS: A randomized control trial was conducted recruiting 216 trauma patients who presented to ED of two tertiary centers. Pain score was done using NRS for all patients. They were randomized into pain score display group or not displayed in the control. The outcome measured were proportion of patients receiving analgesics and timing from triage to analgesic administration.
    RESULTS: The proportion of patients who received analgesics when pain score was displayed was 6.5% more than when pain score was not displayed. This difference was however not statistically significant. However, stratified categorical analysis using chi-square showed that the displayed severe pain group was 1.3 times more likely to receive analgesics compared to the non-displayed group. The mean timing to analgesic administration for the displayed and non-displayed groups were 81.3 ± 41.2 (95% C.I 65.9, 96.7) and 88.7 ± 45.4 (95% C.I 69.0, 108.3), respectively (p > 0.05).
    CONCLUSIONS: The proportion of patients who received analgesics increased when NRS was displayed. However, the pain display has no significant effect on the timing of analgesics.

    Haruan, Channa striatus, is a snakehead fish consumed in many parts of the southeast Asian region. It is believed to promote wound healing, as well as reduce post-operative pain. In an attempt to establish the scientific basis for the alleged pain-relieving benefits of this fish, we studied the antinociceptive effects of whole fillet and mucus extracts from haruan in the mouse using the abdominal constriction and tail flick tests. In the abdominal constriction test, the 30 min fillet extract exhibited concentration-dependent inhibition of the writhing response in the 10-50% concentration range, with 20% as the IC50 value. This activity was not dependent on the duration of extraction, with no significant differences among the extracts obtained at durations of 10, 20, 30, 60, 90 and 120 min (range between 45-54% inhibition at 20% concentration). The mucus extract also showed concentration-dependent inhibition of the abdominal constriction response-at the highest concentration used the average inhibition was 68.9%, while IC50 value was 25%. Neither the fillet extract (30 min, 20%) nor the mucus extract (25%) had any demonstrable effect on the tail flick latency on their own, but significantly enhanced the antinociceptive activity of morphine in this assay. Similarly, low concentrations of the mucus and fillet extract enhanced the effects of morphine in the abdominal constriction test. Collectively, these results suggest a scientific basis for the folklore practice of eating haruan fish in the post-operative period for pain relief: Haruan extracts have antinociceptive activity and enhance the activity of other antinociceptive agents.

    Objective: The main objective of this study was to determine the predictors of frequent oral analgesic use among Rheumatoid Arthritis (RA) patients who were prescribed with the above medication on an ‘as needed’ basis.
    Methods: Patients with RA were recruited consecutively from the Rheumatology outpatient clinics in this cross-sectional study. The sociodemographic data, frequency of oral analgesic intake, Patient Global Assessment (PGA) scores and HAQ (Health Assessment Questionnaire) scores were determined by interviewing the subjects. Subjects were divided into 2 groups; frequent users (3 days and above in a week) and less frequent users (less than 3 days in a week).
    Results: In a total of 112 subjects, 39 (34.8%) were frequent analgesic users. Both the HAQ and PGA scores were significantly higher among the frequent users (p < 0.05). Using multivariate analysis, the HAQ scores (p=0.015, odds ratio 3.161 [95% confidence interval of 1.246-8.015]) and PGA scores (p=0.039 odds ratio 1.291 [95% confidence interval of 1.012-1.646]) were found to be independent predictors of frequent analgesic use.
    Conclusions: Our study confirms that the frequency of analgesic intake in Rheumatoid Arthritis has a significant relationship with patient-reported functional capacity and well being.

    The leaves of a tropical plant, Mitragyna speciosa Korth. (Rubiaceae), have been traditionally used as a substitute for opium. By phytochemical studies on the constituents of the plant growing in Thailand as well as in Malaysia, several 9-methoxy-Corynanthe-type monoterpenoid indole alkaloids including new natural products were isolated. The structures of these new compounds were elucidated by the modern spectroscopic methods and/or chiral-total syntheses. The chiral total synthesis of (-)-mitragynine, a major component of this plant, was achieved. Potent opioid agonistic properties of mitragynine, which acts on mu- and delta-opioid subtype receptors, and of mitragynine pseudoindoxyl, whose analgesic activity is more potent than that of morphine, were clarified in in vitro experiments. The essential structural features in mitragynine for revealing the analgesic activity were elucidated by pharmacological evaluation of the natural and synthetic mitragynine derivatives.

    Opioids are opium-like drugs which are commonly used as analgesics to treat moderate to severe pain. Apoptosis is a type of programmed cell death to remove unnecessary or damaged cells in an organism. Recently, the ability of opioids to induce apoptosis especially in cancer cell lines hasgained the interest of many researchers. This fascinating finding hasled to more testing of different kindsof opioids against different kindsof cancer cell lines in the course to search for the potential anticancer drugs. This review provides current information about opioids and apoptosis, and more importantly the compilations of researches over the years on how opioids are related to apoptotic cells death.

    An HPLC system using a simple liquid-liquid extraction and HPLC with UV detection has been validated to determine tramadol concentration in human plasma. The method developed was selective and linear for concentrations ranging from 10 to 2000 ng/ml with average recovery of 98.63%. The limit of quantitation (LOQ) was 10 ng/ml and the percentage recovery of the internal standard phenacetin was 76.51%. The intra-day accuracy ranged from 87.55 to 105.99% and the inter-day accuracy, 93.44 to 98.43% for tramadol. Good precision (5.32 and 6.67% for intra- and inter-day, respectively) was obtained at LOQ. The method has been applied to determine tramadol concentrations in human plasma samples for a pharmacokinetic study.

    In the management of chronic pain, stepwise oral analgesics of graded strength are
    considered as first-line therapy. Minimally invasive interventional procedures remain an
    option for its treatment when pharmacological therapy fails to control the pain. We
    reported three classical cases of chronic trigeminal neuralgia that were managed with
    two types of pain intervention approaches after failing conservative management. (Copied from article).

    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.

    Pain management in Malaysian Emergency Departments has not been studied well. Convenience sampling was used to recruit 402 patients who presented with acute pain over a 2-week period. The 11-point Numerical Rating Scale was used to quantify pain. Pain relieving medications were prescribed to 178 patients (44.3%) in the Emergency Department. These patients had a median pain score of 7 on arrival. Nonsteroidal anti inflammatory drugs were the most commonly prescribed class of analgesic. Pain was found to be inadequately treated.

    We sought to review the current practice of sedation and analgesia in intensive care units (ICUs) in Malaysian public hospitals. A questionnaire survey was designed and sent by mail to 40 public hospitals with ICU facility in Malaysia. The anaesthesiologists in charge of ICU were asked to complete the questionnaire. Thirty seven questionnaires were returned (92.5% response rate). Only 35% respondents routinely assess the degree of sedation. The Ramsay scale was used prevalently. A written protocol for sedation was available in only 14 centers (38%). Although 36 centers (95%) routinely adjust the degree of sedation according to patient's clinical progress, only 10 centers (14%) interrupt sedation on a daily basis. Most respondents agreed that the selection of agents for sedation depends on familiarity (97%), pharmacology (97%), the expected duration for sedation (92%), patient's clinical diagnosis (89%) and cost (73%). Midazolam (89%) and morphine (86%) were the most commonly used agents for sedation and analgesia, respectively. Only 14% respondents still frequently use neuromuscular blocking agents, mostly in head injury patients. Our survey showed similarity in the choice of sedative and analgesic agents in ICUs in Malaysian public hospitals comparable to international practice. Nevertheless, the standard of practice could still be improved by implementing the practice of sedation score assessment and daily interruption of sedative infusion as well as having a written protocol for sedation and analgesia.

    The present study was carried out to establish the antinociceptive, anti-inflammatory, and antipyretic properties of the aqueous extract of Melastoma malabathricum leaves in experimental animals. The antinociceptive activity was measured using abdominal constriction, hot-plate, and formalin tests, whereas the anti-inflammatory and antipyretic activities were measured using carrageenan-induced paw edema and brewer's yeast-induced pyrexia tests, respectively. The extract, which was obtained after soaking the air-dried leaves in distilled water for 72 h and then preparing in concentrations of 10%, 50%, and 100% (v/v), was administered subcutaneously 30 min prior to subjection to the above mentioned assays. At all concentrations tested, the extract was found to exhibit significant (P < 0.05) antinociceptive, anti-inflammatory, and antipyretic activities in a concentration-independent manner. Our findings that the aqueous extract of M. malabathricum possesses antinociceptive, anti-inflammatory, and antipyretic activities supports previous claims on its traditional uses to treat various ailments.

    A small survey in Peninsular Malaysia indicates a marked tendency among the general population to treat minor ailments by self-medication with over-the-counter drugs and/or traditional medicines. The use of over-the-counter drugs appears to be favoured for skin conditions, general health care, aches and pains, and problems affecting the eyes, ears, mouth, gastrointestinal tract and respiratory tract. A doctor is usually consulted if self-medication fails.

    594 intravenous urograms done at the General Hospital, Ipoh, from January 1981 to March 1985 were reviewed for renal papillary necrosis (RPN). 11 cases (1.8%) of RPN were detected. Of these three were due to diabetes mellitus;eight were due to analgesic nephropathy. There was an equal incidence
    in males and females, contrary to the experience in the West and Australia. RPN was observed mainly in the older age groups. Five of the 11 cases of RPN presented as renal colic.

    A survey was conducted on three different groups of population viz. inpatients in the medical wards of General Hospital, Kuala Lumpur, the people of Kampong Pandan and two rubber estates as to their analgesic consuming habits. It is found that 0.5 to 2.0% of the people surveyed had consumed more than 2 kg of analgesics and 4.6 to 9.6% of the people surveyed had consumed more than 250g of analgesics. The commonest analgesic consumed is paracetamol followed by Chap Kaki Tiga and Chap Harimau. The commonest reason for consuming analgesic is headache. The implications of the above findings are discussed.
