    BACKGROUND: Pain management can be challenging during root canal treatment of teeth with irreversible pulpitis.

    AIM: To identify whether articaine or lidocaine is the most appropriate local anaesthetic solution for teeth with irreversible pulpitis undergoing root canal treatment.

    DATA SOURCE: The protocol of this umbrella review is registered in the PROSPERO database (CRD42019137624). PubMed, EBSCHO host and Scopus databases were searched until June 2019.

    STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS: Systematic reviews published in English comparing the effectiveness of local anaesthesia following administration of articaine or lidocaine in patients undergoing root canal treatment of teeth diagnosed with irreversible pulpitis were included. Two independent reviewers selected the studies and carried out the data extraction and the appraisal of the included reviews. Disagreements were resolved in consultation with a third reviewer.

    STUDY APPRAISAL AND SYNTHESIS METHODS: The quality of the included reviews was appraised by two independent reviewers using the AMSTAR tool (a measurement tool to assess systematic reviews). Each of the 11 AMSTAR items was given a score of 1 if the specific criterion was met, or 0 if the criterion was not met or the information was unclear.

    RESULTS: Five systematic reviews with meta-analyses were included. The AMSTAR score for the reviews ranged from 8 to 11, out of a maximum score of 11, and all reviews were categorized as 'high' quality. Two reviews scored 0 for item 8 in AMSTAR because the scientific quality of the clinical trials included in these reviews was not used in the formulation of the conclusions.

    LIMITATIONS: Systematic reviews published only in the English language were included. Only a small number of studies were available to assess pain intensity during the injection phase, the time until the onset of anaesthesia and the occurrence of adverse events.

    CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Articaine is more effective than lidocaine for local anaesthesia of teeth with irreversible pulpitis undergoing root canal treatment. There is limited evidence that injection of articaine is less painful, has more rapid onset and has fewer adverse events compared with lidocaine.

    Soy-based products are one of famous raw ingredients used in the preparation of Asian cuisines. These soy-based products are good source of isoflavones. This study was carried out to observe the effects of different cooking methods on isoflavone content in soy-based products. A total of eight Malaysian dishes prepared using soy-based products with different cooking methods was selected as samples for this study. Daidzein and genestein contents in raw and cooked soy-based products were both quantified using high performance liquid chromatography (HPLC). The results showed that dishes containing tempe as ingredients had significantly higher (p<0.05) amount of isoflavone content, in both raw and cooked forms, as compared to those prepared from other types of soy-based products when based on dry and wet. In conclusion, the isoflavone content was significantly reduced (p<0.05) in some cooked soy-based products (tempe (TSS and ML), fu jook (ML) and firm tofu (FTC)) based on dry weight as compared with the raw ones. However, the correlations between isoflavone content with cooking methods, durations and temperatures were not significant (p>0.05) in this study.

    Kajian ini dijalankan untuk menentukan kesan perencatan fi tat terhadap bioavailabiliti kalsium (Ca), ferum (Fe) dan zink (Zn) dalam produk kacang soya tempatan terpilih. Fitat menyebabkan kesan perencatan terhadap penyerapan mineral seperti Ca, Fe dan Zn dengan membentuk kompleks yang tidak larut dan tidak dapat dicernakan. Kesan perencatan fi tat terhadap bioavailabiliti mineral seperti Ca, Fe dan Zn telah dianggarkan dengan nisbah molar fi tat kepada mineral. Kandungan fi tat ditentukan dengan menggunakan kaedah pertukaran anion dan kandungan mineral ditentukan dengan Spektrofotometer Serapan Atom (AAS). Produk kacang soya dibeli dari pasar malam dan gerai makanan yang terletak di Cheras dan Sri Rampai, Kuala Lumpur. Setiap sampel yang dibeli dari kedua- dua lokasi dianalisis secara duplikat. Kajian ini mendapati kek soya dan kesemua masakan yang mengandungi tempe tidak mempunyai kandungan fi tat. Ini mungkin disebabkan oleh kehadiran R. oligosporus yang menghasilkan fi tase lalu menghidrolisiskan kandungan fi tat semasa proses fermentasi tempe. Terdapat lima jenis sampel makanan yang mempunyai nisbah molar fi tat/Ca > 0.24, sepuluh jenis sampel makanan dengan nisbah molar fi tat/ Fe > 1, lapan jenis sampel makanan mempunyai nisbah molar fi tat/ Zn > 15 dan satu jenis sampel makanan mempunyai nisbah molar [fi tat x Ca]/ Zn > 200. Keputusan nisbah molar fi tat/ mineral dari kajian ini menganggarkan bioavailabiliti Ca, Fe dan Zn yang rendah. Kesimpulannya, kek soya dan masakan mengandungi tempe mempunyai bioavailabiliti mineral yang tinggi manakala tau-hoo pok bakar mempunyai bioavailabiliti mineral yang rendah.

    This study examined the mechanical (hardness, compressibility, adhesiveness, and cohesiveness) and rheological (zero-rate viscosity and thixotropy) properties of polyethylene glycol (PEG) gels that contain different ratios of Carbopol 934P (CP) and polyvinylpyrrolidone K90 (PVP). Mechanical properties were examined using a texture analyzer (TA-XT2), and rheological properties were examined using a rheometer (Rheomat 115A). In addition, lidocaine release from gels was evaluated using a release apparatus simulating the buccal condition. The results indicated that an increase in CP concentration significantly increased gel compressibility, hardness, and adhesiveness, factors that affect ease of gel removal from container, ease of gel application onto mucosal membrane, and gel bioadhesion. However, CP concentration was negatively correlated with gel cohesiveness, a factor representing structural reformation. In contrast, PVP concentration was negatively correlated with gel hardness and compressibility, but positively correlated with gel cohesiveness. All PEG gels exhibited pseudoplastic flow with thixotropy, indicating a general loss of consistency with increased shearing stress. Drug release T50% was affected by the flow rate of the simulated saliva solution. A reduction in the flow rate caused a slower drug release and hence a higher T50% value. In addition, drug release was significantly reduced as the concentrations of CP and PVP increased because of the increase in zero-rate viscosity of the gels. Response surfaces and contour plots of the dependent variables further substantiated that various combinations of CP and PVP in the PEG gels offered a wide range of mechanical, rheological, and drug-release characteristics. A combination of CP and PVP with complementary physical properties resulted in a prolonged buccal drug delivery.

    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.

    Selective cervical nerve root injection using a mixture of corticosteroid and lignocaine is a treatment option for managing cervical radiculopathic pain. The procedure is usually performed under image guided fluoroscopy or Computerized Tomograhy. Ultrasound-guided cervical nerve root block does not expose the patients and personnel to radiation. During injection, the fluid is mostly visualized in a real-time fashion. This retrospective study reviewed the effectiveness of ultrasound in guiding cervical peri-radicular injection for pain relief in patients with recalcitrant cervical radiculopathy. There were no complications reported in this series.

    Two recent cases of central retinal artery occlusion under otherwise uncomplicated sub-Tenon's block that resulted in significant visual loss after cataract surgery prompted us to undertake a literature review of such cases. We identified 97 cases of retinal artery occlusion after ophthalmic surgery under regional anaesthesia that had no immediate signs of block-related complications. These occurred after various intraocular (87%) and extraocular (13%) operations, across a wide range of ages (19-89 years) on patients with (59%) or without (39%) known risk factors. The anaesthetic techniques included 40 retrobulbar blocks, 36 peribulbar blocks, 19 sub-Tenon's blocks, one topical anaesthetic and one unspecified local anaesthetic. Different strengths of lidocaine, bupivacaine, mepivacaine and ropivacaine, either alone or in various combinations, were used. The details of the anaesthetic techniques were often incomplete in the reports, which made comparison and analysis difficult. Only nine cases had their cause (optic nerve sheath injury) identified, while the mechanism of injury was unclear in the remaining patients. Various mechanisms were postulated; however, the cause was likely to be multifactorial due to patient, surgical and anaesthetic risk factors, especially in those with compromised retinal circulation. As there were no definite risk factors identified, no specific recommendations could be made to avoid this devastating outcome. We have provided rationales for some general considerations, which may reduce this risk, and propose anaesthetic options for ophthalmic surgery on the fellow eye if required, based both on our literature review and our personal experience.

    A fast and simple capillary zone electrophoresis method was developed and validated for the determination of lidocaine in skin using tape samples. Separation was performed in a 350 mm (265 mm to window) x 50 microm i.d. fused silica capillary using a background electrolyte of phosphoric acid-Tris pH 2.5. The extraction of lidocaine from tape samples was achieved using methanol, which was diluted to 50% with water before injection. Procaine was the internal standard. The migration times for procaine and lidocaine were 2.9 and 3.2 min, respectively. The limit of quantification for lidocaine was 50 microg, with signal to noise ratio greater than 10. The calibration curve was linear from 50 to 1000 microg with r(2) greater than 0.99. The CV for both within- and between-assay imprecision and the percentage of inaccuracy for the quality control samples including lower and upper limits of quantitation were 97%. The accuracy and selectivity of this method allowed the measurement of lidocaine in tape samples obtained from a skin tape stripping study of local anesthetics in healthy subjects.

    Lignocaine spray for anaesthetising the nasal mucosa for fibreoptic bronchoscopy often causes discomfort to the patient. We compared two techniques of applying nasal topical anaesthesia using either lignocaine spray (group A: 25 patients) or gel (group B: 30 patients) to assess patients' tolerance to the procedure. Both groups received 100 mg of lignocaine in the nostril, 40-50 mg to oropharynx, 120 mg to vocal cords and 40-100 mg to trachea and bronchi. Throat anaesthesia was the most common unpleasant part experienced by both groups of patients (34.5%), followed by examination of bronchi (30.6%) and nasal anaesthesia (21.8%). Significantly more patients in group A experienced discomfort or pain during nasal anaesthesia as compared to group B (p < 0.001). Patients' tolerance to the bronchoscopy was similar in both groups and the examination was performed satisfactorily in all patients. Thus, lignocaine gel is a simple technique, effective and less irritating as compared to lignocaine spray for topical nasal anaesthesia.

    Effects of ketamine and lidocaine on electroencephalographic (EEG) changes were evaluated in minimally anaesthetized dogs, subjected to electric stimulus. Six dogs were subjected to six treatments in a crossover design with a washout period of one week. Dogs were subjected to intravenous boluses of lidocaine 2 mg/kg, ketamine 3 mg/kg, meloxicam 0.2 mg/kg, morphine 0.2 mg/kg and loading doses of lidocaine 2 mg/kg followed by continuous rate infusion (CRI) of 50 and 100 mcg/kg/min, and ketamine 3 mg/kg followed by CRI of 10 and 50 mcg/kg/min. Electroencephalogram was recorded during electrical stimulation prior to any drug treatment (before treatment) and during electrical stimulation following treatment with the drugs (after treatment) under anaesthesia. Anaesthesia was induced with propofol and maintained with halothane at a stable concentration between 0.85 and 0.95%. Pretreatment median frequency was evidently increased (P < 0.05) for all treatment groups. Lidocaine, ketamine, and morphine depressed the median frequency resulting from the posttreatment stimulation. The depression of median frequency suggested evident antinociceptive effects of these treatments in dogs. It is therefore concluded that lidocaine and ketamine can be used in the analgesic protocol for the postoperative pain management in dogs.

    Fractures of the distal radius are one of the most common types of injuries encountered in hand surgery. Plate osteosynthesis is recommended for unstable fractures. Because distal radius fracture fixation is usually performed under general or regional anesthesia with the use of a tourniquet, this exposes patients, especially elderly people with extensive comorbidities, to adverse effects commonly associated with these forms of anesthesia. As such, many of these patients are unable to undergo surgery in a timely manner until they are deemed medically fit for surgery or anesthesia, and some may still be treated nonsurgically. Injecting local anesthetic of lidocaine and epinephrine into the surgical field and without using a tourniquet is known to be advantageous for various surgical procedures of the hand. However, this approach, also known as wide-awake local anesthesia no tourniquet (WALANT), has not been used in the fixation of fractures beyond the wrist. Using the WALANT approach as an alternative anesthetic for plating of distal radius fractures may enable patients who are normally denied surgery owing to their age or medical comorbidities to undergo plate fixation for the fractures. This article outlines the WALANT approach used for a single case of fixation of distal end radius fracture with a detailed description of the technique of administering local anesthesia.

    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.

    Unintended intravascular injection from inferior alveolar nerve blocks can result in frustrating distant complications affecting such structures as the middle ear and eyes. Possible complications affecting the eyes include blurring of vision, diplopia, mydriasis, palpebral ptosis and amaurosis (temporary or permanent). In this article, we present a complication that has been reported only rarely. Two patients developed transient loss of power of accommodation of the eye resulting in blurred vision after routine inferior alveolar nerve blocks on the ipsilateral side. Clear vision returned within 10-15 minutes after completion of the blocks. The possible explanation for this phenomenon is accidental injection into the neurovascular bundle of local anesthetic agents, which were carried via the blood to the orbital region. This resulted in paralysis of a branch of cranial nerve III, the short ciliary nerves that innervate the ciliary muscle, which controls accommodation.

    We compared the efficacy of IV fentanyl with IV lidocaine as pretreatment for the prevention of withdrawal response after rocuronium injection. For this prospective, randomized, placebo-controlled, double-blind study we recruited 90 patients aged between 18 and 65 yr, ASA physical status I or II, who had undergone elective surgery requiring general anesthesia and positive pressure ventilation. Patients were randomly allocated to 1 of 3 groups: group F received 2 mL IV fentanyl 50 microg/mL (100 microg), group L received 2 mL of preservative-free lidocaine 2% (40 mg), and group P (placebo) received 2 mL of normal saline. The incidence of withdrawal response after rocuronium was 57%, 30%, and 7% in the placebo, lidocaine, and fentanyl groups, respectively. We found a significant reduction in incidence of withdrawal response in both the fentanyl and lidocaine groups when compared with the placebo group (P < 0.05), with the fentanyl group being most effective (P < 0.05). In conclusion, both fentanyl and lidocaine are effective clinical treatments to alleviate the withdrawal response associated with rocuronium injection, with fentanyl being more effective.

    The management of pain during root canal treatment is important. The aim of this systematic review and network meta-analysis was to identify the anaesthetic solution that would provide the best pulpal anaesthesia for inferior alveolar nerve blocks (IANB) treating mandibular teeth with irreversible pulpitis. Two electronic databases (PubMed and Scopus) were searched to identify studies up to October 2018. Randomized clinical trials comparing at least two anaesthetic solutions (lidocaine (lignocaine), articaine, bupivacaine, prilocaine or mepivacaine) used for IANB for treatment of irreversible pulpitis were included. The revised Cochrane risk of bias tool for randomized trials was used to assess the quality of the included studies. Pairwise meta-analysis, network meta-analysis using a random-effects model, and SUCRA ranking were performed. The network meta-analysis estimated the probability of each treatment performing best. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations approach. In total, 11 studies (n = 750) were included in the meta-analysis. The network meta-analysis revealed that only mepivacaine significantly increased the success rate of IANB compared to lidocaine (RR, 1.42 [95% CI 1.04-1.95]). However, no significant differences in the success rate of IANB were observed between mepivacaine and other anaesthetic agents (articaine and bupivacaine). Of all anaesthetic agents, mepivacaine (SUCRA = 0.81) ranked first in increasing the success rate of IANB, followed by prilocaine (SUCRA = 0.62), articaine (SUCRA = 0.54), bupivacaine (SUCRA = 0.41) and lidocaine (SUCRA = 0.13). The overall quality of evidence was very low to moderate. In conclusion, based on the evidence from the randomized clinical trials included in this review, mepivacaine with epinephrine demonstrated the highest probability of providing effective pulpal anaesthesia using IANB for teeth with irreversible pulpitis compared to prilocaine, articaine, bupivacaine and lidocaine. Further, high-quality clinical trials are needed to support the conclusion of this review.
