    A series of preliminary studies was carried out to evaluate the antinociceptive (pain relief) activity of the aqueous extract of Corchorus olitorius L. leaves (COAE) and to determine the influence of temperature and opioid receptors on COAE activity using the abdominal constriction and hot plate tests in mice. COAE, at concentrations of 10, 25, 50, 75, and 100%, showed both peripheral and central antinociception that are non-concentration- and concentration-dependent respectively. The peripheral activity was clearly observed at a concentration of 25% and diminished at a concentration of 100%, while the central activity was observed at all the concentrations of COAE used. Furthermore, the insignificant results obtained indicated that this peripheral activity (at concentrations of 25 and 50%) was comparable to that of morphine (0.8 mg/kg). Pre-heating COAE at a temperature of 80 degrees C and 100 degrees C, or 60 degrees C and 80 degrees C was found to enhance its peripheral and central antinociception respectively. Pre-treatment with naloxone (10 mg/kg), a general opioid receptor antagonist, for 5 min, followed by COAE, was found to completely block its peripheral, but not central, antinociceptive activity. Based on this observation, we conclude that the antinociceptive activity exhibited by C. olitorius is enhanced by the increase in temperature and may be mediated peripherally, but not centrally, at least in part, via an opioid receptor.

    It is still uncertain as to which form of anaesthesia is the optimum. We conducted a study to identify the best location and optimum volume of anaesthetic agent in order to achieve best pain relief and cooperation from our patients. We also assessed the need for local anaesthetic gel for probe lubrication and if the number of cores during biopsy makes a difference in the pain score.

    BACKGROUND: Previous research support the claim that people who work in offices and sit for a long time are particularly prone to musculoskeletal disorders.

    OBJECTIVE: The main objective of this paper is to introduce an exercise training program designed to decrease muscle stiffness and pain that can be performed in the office setting.

    METHODS: Forty healthy office workers (age: 28±5.3 years old; body mass: 87.2±10.2 kg; height: 1.79±0.15 m) apart from suffering from any sub-clinical symptoms of muscle and joint stiffness, and who had at least two years of experience in office work were chosen and randomly assigned to either an experimental group (n = 20) or a control group (n = 20). The experimental group performed the exercise training program three times a week for 11 weeks. The Cornell Musculoskeletal Discomfort Questionnaire was used to measure the pain levels in the neck, shoulders, and lower back areas. The Borg CR-10 Scale was used to measure their perceived exertion when doing the exercises, and a goniometer was used to measure the changes in range of motion (ROM) of the neck, hips, knees, and shoulders.

    RESULTS: The overall results indicated that the exercise program could significantly (p pains of the participants in the exercise group while those in the control group showed no improvement in those pains. There were significant (p pains, but also can improve the ROM or flexibility of the office workers.

    The present study was carried out to investigate on the possible involvement of L-arginine/nitric oxide/cyclic guanosine monophosphate (L-arginine/NO/cGMP) pathway in the aqueous extract of Muntingia calabura (AEMC) leaves antinociception in mice assessed by abdominal constriction test. The AEMC, obtained by soaking the dried leaves in distilled water (DH(2)O) (1 : 2; w/v) for 24 h, was prepared in concentrations of 10%, 50% and 100% that were approximately equivalent to doses of 27, 135 and 270 mg/kg, and administered subcutaneously (s.c.) 5 min after pre-treatment (s.c.) of mice with DH(2)O, L-arginine (20 mg/kg), N(G)-monomethyl-L-arginine acetate (L-NMMA; 20 mg/kg), N(G)-nitro-L-arginine methyl esters (L-NAME; 20 mg/kg), methylene blue (MB) (20 mg/kg), respectively. The AEMC was found to exhibit a concentration-dependent antinociception after pre-challenge with DH(2)O. Interestingly, pre-treatment with L-arginine was found to block significantly (P < 0.05) the AEMC antinociception but only at the highest concentration (100%) of AEMC used. On the other hand, pre-treatment with L-NAME was found to significantly (P < 0.05) enhance the low concentration but inhibit the high concentration AEMC antinociception. MB was found to significantly (P < 0.05) enhance AEMC antinociception at all concentrations used. Except for the higher concentration of AEMC used, co-treatment with L-NAME was found to insignificantly and significantly (P < 0.05) reverse the L-arginine effect when given alone or with low concentration AEMC, respectively. In addition, co-treatment with MB significantly (P < 0.05) reversed the L-arginine effect when given alone or with 10% concentration AEMC but failed to affect the activity of the rest of concentrations used. As a conclusion, this study has demonstrated the involvement of L-arginine/NO/cGMP pathway in AEMC antinociception.

    Subcutaneous (SC) administration of tramadol was compared with intravenous (IV) administration to evaluate analgesia following canine ovariohysterectomy (OHE). Healthy female dogs (n = 12) between 1 and 3 years of age (1.95 ± 0.65 years), weighing between 10.5 and 17.1 kg (13.12 ± 1.95 kg), were used. Pain was assessed at baseline before surgery and then hourly for 8 hr after surgery. Tramadol was administered both SC and IV at a dose of 3 mg/kg and provided significant postoperative analgesia, as indicated by analgesiometry, β-endorphin levels, and interleukin 6 (IL-6) levels. The respiratory rates and rectal temperatures remained normal and were not significantly different between or within the groups. A significant increase in heart rate was observed at 4 hr for dogs in both groups relative to the baseline, but there was no significant difference in heart rates between the groups at any time point. A significant decrease in mechanical pain threshold was observed within each group after surgery, but both groups responded similarly, suggesting that SC administration of tramadol is as effective as IV administration. Increased serum levels of both IL-6 and β-endorphin 3 hr postoperatively further indicate that both routes of administration achieve similar pain control. Thus, the relative analgesic efficacy of SC tramadol is comparable to that of IV administration and can be used to achieve similar effects for postsurgical pain management in dogs undergoing OHE.

    OBJECTIVES: To compare the efficacy of orally administered 10% dextrose, breast milk and sterile water on pain prevention during screening examination for Retinopathy of prematurity (ROP) in preterm neonates as measured by Premature infant pain profile (PIPP).

    METHODS: A three-limbed double-blinded randomized control trial was conducted in a Level 3 neonatal intensive care unit. Forty five preterm neonates undergoing ROP screening were included. Eligible babies were randomly assigned to one of the three groups that orally received either expressed breast milk (n = 14), 10% dextrose solution (n = 14) or sterile water (n = 17), one minute before eye examination. The outcome measure was PIPP score.

    RESULTS: All 3 groups were similar in baseline characteristics. The mean PIPP scores were comparable (p = 0.18) in the three groups (11.8 ± 2.8 vs. 9.8 ± 3.3 vs. 10.2 ± 2.9). The behavioral and physiological variables were also similar across all three groups.

    CONCLUSIONS: Expressed breast milk, 10% dextrose or sterile water administered orally before ROP screening in preterm neonates have similar analgesic effects and do not significantly alleviate pain during the procedure.

    BACKGROUND: Fixation of clavicle fractures has now become a more popular option as it provides better outcome compared with conservative management. Wide-awake local anesthesia no tourniquet (WALANT) has been effectively used in plating of distal radius and olecranon fractures. This paper expands the usage of WALANT into the shoulder girdle, namely plating of the clavicle that has not been described. The operation is typically performed under general anesthesia.

    METHODS: We report a case series of 16 patients who successfully underwent fixation of the clavicle under the wide-awake technique. The clavicle fractures were grouped under the AO Fracture Classification. The WALANT solution comprised 1% lidocaine, 1:100,000 epinephrine, and 10:1 sodium bicarbonate. A total of 40 mL was injected in each patient with 10 mL subcutaneously along the clavicle followed by 30 mL subperiosteally at multiple intervals and directions.

    RESULTS: The Numerical Pain Rating Score was 0 during WALANT injection and during surgery except for 2 patients with Numerical Pain Rating Scores of 1 and 2, respectively, during reduction.

    CONCLUSION: We conclude that clavicle plating under WALANT is a good alternative option of anesthesia.

    BACKGROUND: The success rate of peritoneal dialysis (PD) catheter insertion is known to vary among different operators and may be influenced by many factors such as patient and various situational factors. Traditionally, surgeons have inserted Tenckhoff catheters by mini-laparotomy or an open technique. However, with recent advances in endoscopic instrumentation and video capabilities, peritoneoscope Tenckhoff catheter insertion has become a viable approach in interventional nephrologist-initiated PD access programmes.

    SUMMARY: Nephrologist-initiated peritoneoscopic PD access programs have had a positive impact on PD penetration. The technique has been associated with a better primary success rate, superior catheter survival, less postoperative pain, shorter hospital stay, and shorter catheter break-in time compared with the conventional surgical technique. The role of interventional nephrologists in peritoneoscope Tenckhoff catheter placement is still perceived to be a relatively new advance, investigational by some, and many nephrologists and surgeons alike remain sceptical of the value of this recent option. Crucial questions often raised are how many procedures one needs to perform before being considered competent and who should be credentialed to perform the procedure or supervise trainees performing it. The evaluation of technical proficiency in a specific operation is difficult and complex. Cumulative summation (CUSUM) analysis is one option for tracking the success and failure of technical skill and examining trends over time. Key Messages: The author's facility has had good outcomes with a nephrologist-initiated peritoneoscopic PD access programme. Quality control of PD catheter insertion can be performed using CUSUM charting to monitor for primary catheter dysfunction, primary leak, and primary peritonitis.

    Low back pain is a common musculoskeletal symptom in pregnancy that can present as lumbar pain or pelvic girdle pain, with significant physical and psychosocial implications. Pelvic girdle pain is more prevalent and results in greater disability than lumbar pain. It is possible to distinguish between these two conditions from a detailed history based on the site of the pain, its intensity, disability and pain provocation tests. Management of low back pain in pregnancy is conservative, with physical exercise for lumbar pain and minimising activities that exacerbate pain, analgesics and bed rest for pelvic girdle pain, as well as avoiding abduction beyond the pain-free zone in labour. There is evidence that stabilising exercises in patients with pelvic girdle pain postpartum have a beneficial effect. Other treatment modalities that have been shown to be safe and effective include pelvic belts, transcutaneous electrical nerve stimulation, spinal manipulative therapy, acupuncture and complementary therapy with yoga. Other orthopaedic complications in pregnancy such as carpal tunnel syndrome, pubic symphysis rupture, transient osteoporosis and osteonecrosis are usually self-limiting with a satisfactory outcome. However, a lack of awareness and failure to recognise these complications can result in long-term morbidity. Knowledge of the preoperative diagnostic investigations, surgical approaches and intraoperative positioning of the mother to avoid gravid uterus compression is vital in orthopaedic emergencies such as lumbar disc herniation, cauda equina syndrome, fractures and acute compartment syndrome of the lower limb to ensure a safe maternal and fetal outcome and to prevent serious disability. Pregnancy is not contraindicated in women with pre-existing orthopaedic complications such as kyphoscoliosis and total hip arthroplasty as there is no evidence to suggest increased maternal or fetal risks.

    AIMS: Magnetic resonance guided focused ultrasound (MRgFUS) is a new modality in the management of primary and secondary bone tumors. We aimed to investigate the safety, efficacy, and feasibility of using MRgFUS for the treatment of (1) benign bone tumors with the intent of complete tumor ablation, (2) primary malignant bone tumors with the intent to assess its effectiveness in causing tumor necrosis, and (3) metastatic bone disease with the intent of pain relief.

    METHOD: Twenty-four patients with benign bone tumors, primary malignant bone tumors, and metastatic bone disease were treated with one session of MRgFUS. Contrast-enhanced (CE) magnetic resonance imaging (MRI) was carried out post-procedure to assess and quantify the area of ablation. Those with malignant primary tumors had the tumors resected 2 weeks after the treatment and the ablated areas were examined histopathologically (HPE). The other patients were followed up for 3 months to assess for the side effects and pain scores.

    RESULTS: Significant volume of ablation was noted on CE MRI after the treatment. Benign bone tumors were ablated with minimal adverse effects. Metastatic bone disease was successfully treated with significant decrease in pain scores. Ablated primary malignant tumors showed significant coagulative necrosis on MRI and the HPE showed 100% necrosis. Pain scores significantly decreased 3 months after the procedure. Only two patients had superficial skin blistering and three patients had increase in pain scores immediately after treatment.

    CONCLUSION: MRgFUS is effective, safe, and noninvasive procedure that can be an adjunct in the management of primary and metastatic bone tumors.

    The study compared the effectiveness of ketamine and midazolam/fentanyl as procedural sedation and analgesia agents for reduction of fractures and dislocated joints. Forty-one adult patients were enrolled by convenience sampling. They were randomized to receive ketamine or midazolam/fentanyl. Depth of sedation, pain score, procedural outcome and memory of the procedure were documented. The ketamine group had deeper sedation, but there was no statistical difference in other variables between the two groups. Three patients in the midazolam/fentanyl group had oxygen desaturation. More adverse effects were associated with ketamine. Intravenous ketamine is as effective as midazolam/fentanyl for procedural sedation.

    The prevalence of low back pain (LBP) among nurses is high. The main aim of this study was to evaluate the effectiveness of an interactive LBP module based on the Back School Program in improving Oswestry Disability Scores (ODSs) among nurses in government hospitals in Penang, Malaysia. A cluster-randomized experimental study was conducted within four public hospitals. These hospitals were randomized to intervention and control groups. A total of 284 nurses from the selected hospitals were randomly selected (142 in each group). An interactive LBP intervention module based on the Back School Program was designed and prescribed. Both the intervention and control groups were assessed using the Oswestry Disability Questionnaire at baseline and at the end of the third and sixth weeks. Out of 284 participants, 281 completed this study. A between-group comparison revealed that ODSs were significantly lower in the intervention group than in the control group at the ends of the third (p = 0.006) and sixth weeks (p < 0.001). Within-group changes revealed a significant reduction in ODSs within the intervention group from baseline to the third (p < 0.001) and sixth weeks (p < 0.001) of the intervention. This simple interactive LBP module was effective in reducing symptoms of LBP among nurses as early as three weeks, and this effect was sustained until the sixth week of the intervention.

    Within Malaysia's otherwise highly accessible public healthcare system, palliative medicine is still an underdeveloped discipline. Government surveys have shown that opioid consumption in Malaysia is dramatically lower than the global average, indicating a failure to meet the need for adequate pain control in terminally ill patients. Indeed, based on daily defined doses, only 24% of patients suffering from cancer pain receive regular opioid analgesia. The main barriers to effective pain control in Malaysia relate to physicians' and patients' attitudes towards the use of opioids. In one survey of physicians, 46% felt they lacked knowledge to manage patients with severe cancer pain, and 64% feared effects such as respiratory depression. Fear of addiction is common amongst patients, as is confusion regarding the legality of opioids. Additional barriers include the fact that no training in palliative care is given to medical students, and that smaller clinics often lack facilities to prepare and stock cheap oral morphine. A number of initiatives aim to improve the situation, including the establishment of palliative care departments in hospitals and implementation of post-graduate training programmes. Campaigns to raise public awareness are expected to increase patient demand for adequate cancer pain relief as part of good care.

    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.
