    This is a prospective randomized clinical trial to compare use of a combination of periarticular drug injection with patientcontrolled analgesia (PCA) to PCA alone in post-total knee arthroplasty (TKA). Thirty patients who were admitted for unilateral total knee arthroplasty were selected randomly into an Injection group or a Standard group. The periarticular injection contained Ropivacaine, Ketorolac and Adrenaline, given intra-operatively. The mean amount of opioid used was 22.87 mmol/L in the Injection group as compared to 39.78 mmol/L in the Standard group (p = 0.026). The Injection group had lower pain score at rest and during exercise (p=0.021, p=0.041, respectively), as well as better return to function (p=0.026) and shorter hospital stay (6.1 days, Injection; 7.5 days, Standard, p=0.027). Overall, the group receiving periarticular drugs injection had less pain, less narcotic usage, earlier return to function, similar experience of adverse effects and shorter hospital stays.

    The use of herbal preparations remained the main approach of folk medicine to the treatment of ailments and debilitating diseases. Initial intensive researches conducted on Lemongrass extracts (tea) may have showed conflicting evidences, however the resurgence in claims of folk medicine practitioners necessitated further inquiry into the efficacy of the tea. Lemongrass tea contains several biocompounds in its decoction, infusion and essential oil extracts. Anti-oxidant, anti-inflammatory, anti-bacterial, anti-obesity, antinociceptive, anxiolytic and antihypertensive evidences of lemongrass tea were clearly elucidated to support initial pharmacological claims. Lemongrass tea was non-toxic, non-mutagenic and receives wide acceptance among alternative medicine practitioners in several developing countries. This review therefore presents previous research activities, technologies and information surrounding bioactivities of lemongrass tea. Areas of future researches which may elucidate mechanisms of the biological properties of lemongrass extracts were highlighted.

    Chronic idiopathic facial pain is the diagnosis given to a group of orofacial pain of psychogenic origin which includes atypical facial pain, facial-arthromyalgia, atypical odontalgia and oral dysaesthesia. Despite various biochemical findings, the condition remains poorly understood, but we have begun to understand the nature of these patients. This review discusses the possible aetiology of the disease through various biochemical and clinical findings. The contribution of behavioural and psychological factors to the clinical course of the disease are described. The type of adverse life events that predispose people to the disease and their potency are briefly mentioned. The current diagnostic approach for the disease is also mentioned. Treatment includes antidepressant medication, physiotherapy, bite-guards and analgesics. The problems encountered in the long-term management and outcome studies of these patients include drop-outs, non-compliance and denial.

    Phantom limb pain may reduce ambulation and mobility in amputees, resulting in diminished quality of life. We conducted a prospective study to compare the perioperative analgesic use of intravenous morphine infusion in 27 patients(Group A) and intramuscular diclofenac sodium in 28 patients (Group B) in patients undergoing lower limb amputation. All patients underwent amputation under spinal anaesthesia and reported a Modified Verbal Numerical Pain Score of less than two prior to the procedure. Presence of phantom pain was assessed on the first, second, third and seventh day as well as at the third month and sixth month post-operatively. Twelve (44 %) patients from group A and 21 patients (75 %) from group B developed phantom limb pain following amputation, a statistically significant difference between groups (p

    It is important to provide effective postoperative analgesia following a Caesarean section because mothers wish to be pain-free, mobile and alert while caring for their babies. The role of regular oral diclofenac as postoperative analgesia was evaluated in a randomized controlled study and it was compared to the established method of parenteral pethidine. Forty healthy women scheduled for elective Caesarean section under spinal anaesthesia with 2-2.5 mg of heavy bupivacaine 0.5% were randomized to receive either 75 mg of oral diclofenac twice daily or 1 mg/kg of subcutaneous pethidine every 8 hourly. Efficacy of pain relief (visual analogue score), patients' satisfaction and side effects such as sedation, nausea and vomiting were recorded for three days. The demographic variables were similar in both groups. Pain relief was adequate and comparable in both groups with similar mean visual analogue score during the second and third day of the study period. However, on the first postoperative day, 60% of the diclofenac group population required rescuemedication consisting of subcutaneous pethidine in order to achieve the same pain scores as those in the pethidine group who did not require any rescue medications. Women who received oral diclofenac reported lower sedation and higher overall satisfaction. The incidence of nausea and vomiting was similar in both groups. This concluded that although oral diclofenac 75mg twice daily may not be superior to the traditional method of subcutaneous pethidine for pain relief following caesarean section, it can still be used alone as an alternative, as it has other benefits of a non-opioid analgesia.

    Introduction and Objectives: The intensive care unit (ICU) is an uncomfortable and stressful environment for patients. The use of adequate sedation and analgesia is important to reduce stress to patients. The aim of this study was to compare a relatively new sedative agent, dexmedetomidine to current sedative agent used, propofol in the provision of sedation and analgesia, their effects on haemodynamic and respiratory parameters and cost involved on post open heart surgery patients. Materials and Methods: A prospective, randomized single-blinded trial was conducted on post open heart surgery patients in the ICU of the Hospital Universiti Sains Malaysia (HUSM). Thirty two patients were randomized to dexmedetomidine or propofol groups. Analgesic requirement, haemodynamic and respiratory parameters, and extubation time were measured and compared. Mean rate of infusion to achieve adequate sedation were used to calculate the cost involved in the use of these two agents. Results: Patients sedated with dexmedetomidine required significantly lower dose of morphine compared to propofol [mean (sd): 12.80 (2.61) versus 15.86 (1.87) mg/kg/min, p=0.00]. Mean heart rate was also significantly lower in dexmedetomidine group compared to propofol group [mean (CI): 74.48 (70.38,78.59) versus 83.85 (79.61,88.09) per minutes, p=0.00]. However there were no significant differences in the other parameters between the two groups. Cost involved the use of dexmedetomidine was slightly higher compared to propofol (RM 9.57 versus RM8.94 per hour). Discussion and Conclusions: Dexmedetomidine is comparable to propofol in the provision of sedation, and its effect on haemodynamic and respiratory parameters. However it has added advantages in the provision of analgesia, and caused a significant reduction in heart rate. This is beneficial in these patients by reducing myocardial oxygen demand, and hence subsequent ischaemia and infarction. However, further larger studies are needed to evaluate the effect of dexmedetomidine on perioperative cardiac morbidity and mortality.

    Objective: This study was conducted to assess the effects of Methadone Maintenance Therapy (MMT) and buprenorphine-naloxone Maintenance Therapy (BNX) on the Quality of life (QoL) of opiate abusers. Methods: The QoL status of opioid-dependent patients was assessed using the WHOQOL-BREF questionnaire. It is a cross-sectional study involving a total of 108 patients who received MMT or BNX therapy in Malaysia from May 2011 to September 2011. Results: A statistically significant difference in the overall QoL and psychological aspect among patients on MMT was observed. On the contrary, the scores of overall QoL and quality of social relationship for BNX group were higher in patients with lower dosage. Conclusion: The comparison between patients on high dose MMT and high dose BNX exhibited significant difference in the overall QoL especially in psychological, social relationship and environment domains, with the high dose MMT group having better mean score.

    MRI can be a distressing and traumatic experience in many patients, especially in those with underlying anxiety and/or claustrophobia. We conducted a study to determine if dexmedetomidine as a sedative agent can alleviate these symptoms. Dexmedetomidine is a potent and highly selective α-2 adrenergic receptor agonist which has sedative and analgesic properties. Eleven adult patients (n=11) with a histroy of anxiety and/or claustrophobia undergoing MRI who expressed their desire for sedation were recruited. Dexmedetomidine was infused at 0.5 to 1.0 μg/kg over 10 minutes prior to scanning. Eight patients (n=8) were able to complete the MRI scan comfortably. The findings suggest that dexmedetomidine provides adequate sedation that can allow patients with anxiety and/or claustrophobia to undergo MRI scanning succesfully in a large poproption of the population with anxiety. This result however is still preliminary and will need to be validated in a more robust clinical study.

    Introduction: Total knee arthroplasty (TKA) is associated with intense postoperative pain for which effective analgesia is essential to facilitate early postoperative recovery. Adductor canal block (ACB) and local infiltration analgesia (LIA) have become increasingly involved in postoperative pain management after TKA. We aimed to compare their efficacy and outcomes in patients undergoing TKA. Materials and Methods: Sixty patients undergoing unilateral TKA were randomized to receive either postoperative single-injection ACB (Group A) or LIA (Group L) during the operation. All patients received spinal anaesthesia. Primary outcome was total morphine consumption over postoperative 24 hours. Visual analog pain scale, time to first and total dosage of rescue analgesia, performance-based evaluations [timed-up and go (TUG) test, quadriceps strength], side-effects, length of hospital stay and patient satisfaction were measured. Results: Fifty-seven patients were available for analysis. Median total morphine consumption over 24 and 48 postoperative hours of Group A were significantly less than Group L (6/10 mg vs 13/25 mg, p, 0.008 and 0.001, respectively). Similarly, Group A had significantly lower VAS at postoperative 6, 12 and 18 hours, VAS at ambulation on postoperative (POD) 1-3, better TUG tests on POD 2 and during POD 3 than those of Group L. However, quadriceps strength and patient satisfaction were not different between both groups. Conclusion: Patients undergoing TKA with single-injection ACB required less postoperative opioids than those with LIA. Furthermore, multimodal analgesia using ACB provided better postoperative analgesia, as well as performance-based activities, than those with LIA.

    PURPOSE OF REVIEW: To describe models of integrated and co-located care for opioid use disorder (OUD), hepatitis C (HCV), and HIV.

    RECENT FINDINGS: The design and scale-up of multidisciplinary care models that engage, retain, and treat individuals with HIV, HCV, and OUD are critical to preventing continued spread of HIV and HCV. We identified 17 models within primary care (N = 3), HIV specialty care (N = 5), opioid treatment programs (N = 6), transitional clinics (N = 2), and community-based harm reduction programs (N = 1), as well as two emerging models. Key components of such models are the provision of (1) medication-assisted treatment for OUD, (2) HIV and HCV treatment, (3) HIV pre-exposure prophylaxis, and (4) behavioral health services. Research is needed to understand differences in effectiveness between co-located and fully integrated care, combat the deleterious racial and ethnic legacies of the "War on Drugs," and inform the delivery of psychiatric care. Increased access to harm reduction services is crucial.

    Mitragyna speciosa is a psychoactive plant known as "ketum" in Malaysia and "kratom" in Thailand. This plant is distinctly known to produce two important alkaloids, namely mitragynine (MG) and 7-hydroxymitragynine (7-OH-MG) that can bind to opioid receptors [1]. MG was reported to exhibit antidepressant properties in animal studies [2]. These compounds were also proposed to have the potential to replace opioid analgesics with much lower risks of side effects [3]. To date, there are only over 40 metabolites identified in M. speciosa [4,5]. To obtain a more complete profile of secondary metabolites in ketum, we performed metabolomics study using mature leaves of the green M. speciosa variety. The leaf samples were extracted using methanol prior to liquid chromatography-electrospray ionization-time of flight-mass spectrometry (LC-ESI-TOF-MS) analysis. This data can be useful to for the identification of unknown metabolites that are associated with alkaloid biosynthesis pathway in M. speciosa.

    BACKGROUND: Low frequency sound wave stimulation therapy has become increasingly popular in the rehabilitation fields, due to its ease, less fatiguing and time efficient application.

    OBJECTIVE: This 12-week pilot study examines the efficacy of applying low frequency sound wave stimulation (between 16-160 Hz) through both hands and feet on relieving pain and improving functional ability in patients with chronic back pain.

    METHODS: Twenty-three participants with chronic shoulder (eleven participants) or low back pain (twelve participants) underwent a 12-week vibration therapy program of three sessions per week. A low frequency sound wave device comprising four piezoelectric vibration-type tactile tranducers enclosed in separate 5-cm diameter circular plates, which generate sinusoidal vibratory stimuli at a frequency of 16-160 Hz, was used in this study. Primary outcome measure was pain sensation measured using the Visual Analogue Scale (P-VAS). The secondary outcome measures were pain-related disability measured using the pain disability index (PDI) and quality of life measured using the SF-12.

    RESULTS: At week 12, significant reductions in pain sensation and pain-related disability were observed, with mean reductions of 3.5 points in P-VAS and 13.5 points in the PDI scores. Sixty-five percent of the participants had a reduction of at least 3 points on the P-VAS score, while 52% participants showed a decrease of at least 10 points in the PDI score. Significant improvement was observed in the SF-12 physical composite score but not the mental composite score.

    CONCLUSIONS: The preliminary findings showed that passive application of low frequency sound wave stimulation therapy through both hands and feet was effective in alleviating pain and improving functional ability in patients with chronic back pain.

    Limited data are available on the adherence to opioid therapy and the influence of different patient groups on adherence. This study examined the patterns of adherence in opioid naïve and opioid existing patients with varying age and gender. This retrospective cohort study was conducted using the prescription databases in tertiary hospital settings in Malaysia from 2010 to 2016. Adult patients aged ≥18 years, receiving at least two opioid prescriptions, were included and stratified into the opioid naïve and existing patient groups. Adherence to opioid therapy was measured using the proportion of days covered (PDC), which was derived by dividing the total number of days covered with any opioids by the number of days in the follow-up period. Generalized linear modeling was used to assess factors associated with PDC. A total of 10,569 patients with 36,650 prescription episodes were included in the study. Of these, 91.7% (n = 9,696) were opioid naïve patients and 8.3% (n = 873) were opioid existing patients. The median PDC was 35.5% (interquartile range (IQR) 10.3-78.7%) and 26.8% (IQR 8.8-69.5%) for opioid naïve and opioid existing patients, respectively. A higher opioid daily dose (coefficient 0.010, confidence interval (CI) 0.009, 0.012 p < 0.0001) and increasing age (coefficient 0.002, CI 0.001, 0.003 p < 0.0001) were associated with higher levels of PDC, while lower PDC values were associated with male subjects (coefficient -0.0041, CI -0.072, -0.010 p = 0.009) and existing opioid patients (coefficient -0.134, CI -0.191, -0.077 p < 0.0001). The suboptimal adherence to opioid medications was commonly observed among patients with non-cancer pain, and the opioid existing patients were less adherent compared to opioid naïve patients. Increasing age and a higher daily opioid dose were factors associated with higher levels of adherence, while male and opioid existing patients were potential determinants for lower levels of adherence to opioid medications.

    Introduction: Substance abuse is both a social and public health problem with a substantial burden to society. Opioid dependence results in unemployment, crimes, family disruption, and transmission of diseases. In Malaysia, methadone maintenance therapy (MMT) has been introduced as a harm reduction method. However, relapse during treatment remains an issue to be resolved that hinders successful outcome in the therapy. Spirituality in the treatment of substance abuse disorders has yet to be fully explored. This study aims to examine how MMT clients who relapsed perceive spiritual deficits as an influence and association of spiritual practice with relapse. Methods: This is a cross-sectional study done from June-July 2016. All MMT clients undergoing therapy at 3 treatment centers in Terengganu, Malaysia who fulfilled the inclusion and exclusion criteria and consented were included in the study. A semi-structured questionnaire was filled via face to face interview and spiritual practice was assessed using Hatta Islamic Religiosity Scale. 121 questionnaires were assessed and data was analyzed using SPSS version 22 for quantitative data. Results: All respondents were males of Malay race and Islamic religion. Current relapse, defined as any episode of intake of opioid for the past one month after a period of abstinence was 34%. Only three out of 42 clients who relapsed had some spirituality theme in their perceived cause of their relapse. However, a significant majority of those relapsed had a spiritual practice score of less than the mean practice score. Conclusion: Relapse in opioid addiction remains high in those receiving MMT in Terengganu, Malaysia. Spirituality may have a subconscious influence towards relapse in addiction in MMT clients. Further effort should be taken to inculcate spirituality intervention effective to prevent relapse which may contribute towards achieving a more successful therapy outcomes.

    The main objectives in this study were to determine the percentage of psychiatric comorbidity among treatment seeking opioid dependents in Klang Valley. A cross sectional study of opioid dependence patients was conducted between December 2007 and May 2008 at ten community-based drug substitution therapy clinics in Klang Valley. A total of 204 opioid dependence patients participated in the study using the structured clinical interview for DSM-IV Axis I disorders
    (SCID-I) as its instruments. The percentage of psychiatric comorbidity among opioid dependents was 43.6%. Major depressive disorder had the highest prevalence at 32.6%, followed by dysthymia at 23.6% and Panic disorder at 14.6%. Psychiatric comorbidity were found to have significant differences (p<0.05) in connection with history of polysubstance abuse, previous history of court sentences (legal status) and family history of psychiatric illnesses. This study showed that the percentage of psychiatric comorbidity is high among the opioid dependents. It highlights the urgent need for the psychiatric comorbidity to be assessed and early intervention is important for this group of patients.

    Introduction: Non-pharmacological interventions are considered as successful adjuncts to manage pain. We are studying the comparative effects of listening to prayer recitation and music therapy intraoperatively as non-pharmacological interventions on postoperative pain and intraoperative haemodynamics. Materials and Methods: Seventy two muslim patients with acute appendicitis requiring open, emergency appendicectomies under general anaesthesia were recruited and randomised into three groups: Group A: patients who listened to prayer recitation, Group B: patients who listened to music, Group C: control group - patients who did not listen to any prayer or music. Intraoperative blood pressure, heart rate and postoperative pain scores were monitored. Results: The demographic data, pre- and post-headphones application haemodynamics were compared. There were significantly lower heart rates at 10, 20, 30, 40, 50, 60 minutes for Group A and at 50 and 60 minutes for Group B patients when compared to Group C. Significant reduction in postoperative pain scores were seen in Group A patients at 30 minutes and 8 hours as compared to Group C patients. No significant differences in pain scores were seen between Group B and C patients. No significant differences in additional analgesic requirements postoperatively were seen in all three groups. Conclusion: Listening to prayer recitation or music intraoperatively significantly lowered intraoperative heart rates, however only prayer recitation significantly reduced postoperative pain scores as compared to the control group.

    Southeast Asian countries including Malaysia play a major role in global drug trade and abuse. Use of amphetamine-type stimulants has increased in the past decade in Malaysia. This study aimed to apply wastewater-based epidemiology for the first time in Kuala Lumpur, Malaysia, to estimate the consumption of common illicit drugs in urban population. Influent wastewater samples were collected from two wastewater treatment plants in Kuala Lumpur in the summer of 2017. Concentrations of twenty-four drug biomarkers were analyzed for estimating drug consumption. Fourteen drug residues were detected with concentrations of up to 1640 ng/L. Among the monitored illicit drugs, 3,4-methylenedioxy-methamphetamine (MDMA) or ecstasy had the highest estimated per capita consumptions. Consumption and dose of amphetamine-type stimulants (methamphetamine and MDMA) were both an order of magnitude higher than those of opioids (heroin and codeine, methadone and tramadol). Amphetamine-type stimulants were the most prevalent drugs, replacing opioids in the drug market. The prevalence trend measured by wastewater-based epidemiology data reflected the shift to amphetamine-type stimulants as reported by the Association of Southeast Asian Nations Narcotics Cooperation Center. Most of the undetected drug residues were new psychoactive substances (NPSs), suggesting a low prevalence of NPSs in the drug market.

    Background and Aim: Laboratory mice are widely used as a research model to provide insights into toxicological studies of various xenobiotic. Acetaminophen (APAP) is an antipyretic and analgesic drug that is commonly known as paracetamol, an ideal hepatotoxicant to exhibit centrilobular necrosis in laboratory mice to resemble humans. However, assessment of histopathological changes between mouse strains is important to decide the optimal mouse model used in APAP toxicity study. Therefore, we aim to assess the histomorphological features of APAP-induced liver injury (AILI) in BALB/C and Institute of Cancer Research (ICR) mice.

    Materials and Methods: Twenty-five ICR mice and 20 BALB/C mice were used where five animals as control and the rest were randomly divided into four time points at 5, 10, 24 and 48 hours post-dosing (hpd). They were induced with 500 mg/kg APAP intraperitoneally. Liver sections were processed for hematoxylin-eosin staining and histopathological changes were scored based on grading methods.

    Results: Intense centrilobular damage was observed as early as 5 hpd in BALB/C as compared to ICR mice, which was observed at 10 hpd. The difference of liver injury between ICR and BALB/C mice is due to dissimilarity in the genetic line-up that related to different elimination pathways of APAP toxicity. However, at 24 hpd, the damage was markedly subsided and liver regeneration had taken place for both ICR and BALB/C groups with evidence of mitotic figures. This study showed that normal liver architecture was restored after the clearance of toxic insult.

    Conclusion: AILI was exhibited earlier in BALB/C than ICR mice but both underwent liver recovery at later time points.
