    A 72 year old man developed acute organic brain syndrome associated with marked eosinophilia following self medication with a variety of drugs. Investigations revealed no other known causes of eosinophilia. Withdrawal of drugs resulted in dramatic drop in eosinophil count paralleled by clinical resolution of neurological problems. To our knowledge drug-induced eosinophilia has not previously been associated with acute organic brain syndrome.

    INTRODUCTION: Water-soluble, but not lipid-soluble, extract of Dicranopteris linearis leaves has been proven to possess hepatoprotective activity. The present study aimed to validate the hepatoprotective and antioxidant activities, and phytoconstituents of lipid-soluble (chloroform) extract of D. linearis leaves.

    METHODS: The extract of D. linearis leaves (CEDL; 50, 250 and 500 mg/kg) was orally administered to rats for 7 consecutive days followed by the oral administration of 3 g/kg PCM to induce liver injury. Blood was collected for liver function analysis while the liver was obtained for histopathological examination and endogenous antioxidant activity determination. The extract was also subjected to antioxidant evaluation and phytochemicals determination via phytochemical screening, HPLC and UPLC-HRMS analyses.

    RESULTS: CEDL exerted significant (p

    OBJECTIVE: Clinical guidelines recommend exercise as a core treatment for knee or hip osteoarthritis (OA). However, how its analgesic effect compares to analgesics, for example, oral non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol-the most commonly used analgesics for OA, remains unknown.

    DESIGN: Network meta-analysis.

    DATA SOURCES: PubMed, Embase, Scopus, Cochrane Library and Web of Science from database inception to January 2022.

    ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled trials (RCTs) comparing exercise therapy with oral NSAIDs and paracetamol directly or indirectly in knee or hip OA.

    RESULTS: A total of n=152 RCTs (17 431 participants) were included. For pain relief, there was no difference between exercise and oral NSAIDs and paracetamol at or nearest to 4 (standardised mean difference (SMD)=-0.12, 95% credibility interval (CrI) -1.74 to 1.50; n=47 RCTs), 8 (SMD=0.22, 95% CrI -0.05 to 0.49; n=2 RCTs) and 24 weeks (SMD=0.17, 95% CrI -0.77 to 1.12; n=9 RCTs). Similarly, there was no difference between exercise and oral NSAIDs and paracetamol in functional improvement at or nearest to 4 (SMD=0.09, 95% CrI -1.69 to 1.85; n=40 RCTs), 8 (SMD=0.06, 95% CrI -0.20 to 0.33; n=2 RCTs) and 24 weeks (SMD=0.05, 95% CrI -1.15 to 1.24; n=9 RCTs).

    CONCLUSIONS: Exercise has similar effects on pain and function to that of oral NSAIDs and paracetamol. Given its excellent safety profile, exercise should be given more prominence in clinical care, especially in older people with comorbidity or at higher risk of adverse events related to NSAIDs and paracetamol.CRD42019135166.

    Postoperative pain is generally a novel experience among paediatric patients. Topical anaesthetics, distraction procedures, and buffering of anaesthetic solutions have been used in reducing the postoperative pain. In this review, the authors assessed various modalities used to alleviate postoperative pain in children's dental treatment under general anaesthesia. Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol were strictly adhered to in this systematic review. Specific keywords including postoperative pain, general anaesthesia, children, and dental extraction were used in the search for relevant randomized control trial studies in Web of Science, Scopus and PubMed, and included articles published until June 2021. From a total of 191 abstracts, 21 were reviewed. From the six studies with the usage of non-steroidal anti-inflammatory drugs (NSAIDs) alone or in combination with paracetamol, four observed that the preoperative use of NSAIDs alone or in combination was better than paracetamol alone, one discovered preoperative intravenous paracetamol was better than postoperative intravenous paracetamol, and the remaining study found no difference among various groups. Of two studies comparing the usage of non-steroidal anti-inflammatory drugs with opioid analgesics, one stated intravenous fentanyl in combination was better, while the other study found no difference among groups. The results obtained in this review can be utilized by physicians to control postoperative pain in children undergoing dental treatment under general anaesthesia.

    Identifying indices of poor prognosis at first presentation after acetaminophen poisoning is the key to both improving clinical care and determining targets for intervention. This study intended to document the prevalence, clinical characteristics and predictors of vomiting and to investigate the relationship between episodes of vomiting at first hospital presentation and outcome in acetaminophen poisoning. This retrospective cohort study included patients who attended the emergency department and were admitted within 24 hr of acetaminophen ingestion. The study was conducted over a period of 5 years from 1 January 2004 to 31 December 2008. Parametric and non-parametric tests were used to test differences between groups depending on the normality of the data. SPSS 15 was used for data analysis. Data from 291 patients were included. Vomiting was present in 65.3% of patients with acetaminophen poisoning at the time of first presentation. Multiple logistic regression showed that significant risk factors for vomiting were present among patients who reported an ingested dose of acetaminophen ≥10 g (p < 0.001) and a latency time of more than 8 hr (p = 0.030). Overall, an increasing trend in prothrombin time (p = 0.03), serum bilirubin (p < 0.001), serum creatinine (p = 0.005), serum potassium (p < 0.001), length of hospital stay (p < 0.001) and the prevalence of patients who had a serum acetaminophen level above a 'possible toxicity' treatment line (p = 0.001) were associated with an increased number of episodes of vomiting. In conclusion, vomiting was common among patients with acetaminophen poisoning. This study suggests that an increase in episodes of vomiting at first presentation appears to be an important risk marker of subsequent nephrotoxicity and hepatotoxicity.

    Paracetamol (PCM)-loaded composite nanoparticles (NPs) composed of a biodegradable poly(d,l-lactide) (PLA) polymer matrix filled with organically modified montmorillonite (MMT) nanoparticles were fabricated by antisolvent nanoprecipitation in a microfluidic co-flow glass capillary device. The incorporation of MMT in the polymer improved both the drug encapsulation efficiency and the drug loading, and extended the rate of drug release in simulated intestinal fluid (pH 7.4). The particle size increased on increasing both the drug loading and the concentration of MMT in the polymer matrix, and decreased on increasing the aqueous to organic flow rate ratio. The drug encapsulation efficiency in the NPs was higher at higher aqueous to organic flow rate ratio due to faster formation of the NPs. The PCM-loaded PLA NPs containing 2 wt% MMT in PLA prepared at an aqueous to organic flow rate ratio of 10 with an orifice size of 200 μm exhibited a spherical shape with a mean size of 296 nm, a drug encapsulation efficiency of 38.5% and a drug loading of 5.4%. The encapsulation of MMT and PCM in the NPs was confirmed by transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis and attenuated total reflection-Fourier transform infrared spectroscopy.

    The data in this article provide information on spectroscopic and theoretical data for p-chlorocalix[4]arene when combined with selected drugs, such as paracetamol, ibuprofen, and cetirizine. The present spectroscopic data are generated from Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (1H NMR and 13C NMR), and Ultraviolet-Visible spectroscopy (UV-Vis) as the key tools for molecular characterization. The measurement of the optimization energy, interaction energy, and the band gap energy between the molecules was calculated by Gaussian 09 software. It is interesting to note that of the three titled drugs identified, p-chlorocalix[4]arene showed the highest interaction energy with paracetamol, followed by ibuprofen and cetirizine.

    Rice starch is a promising biomaterial for thin film development in buccal drug delivery, but the plasticisation and antiplasticisation phenomena from both plasticisers and drugs on the performance of rice starch films are not well understood. This study aims to elucidate the competing effects of sorbitol (plasticiser) and drug (antiplasticiser) on the physicochemical characteristics of rice starch films containing low paracetamol content. Rice starch films were prepared with different sorbitol (10, 20 and 30% w/w) and paracetamol contents (0, 1 and 2% w/w) using the film casting method and were characterised especially for drug release, swelling and mechanical properties. Sorbitol showed a typical plasticising effect on the control rice starch films by increasing film flexibility and by reducing swelling behaviour. The presence of drugs, however, modified both the mechanical and swelling properties by exerting an antiplasticisation effect. This antiplasticisation action was found to be significant at a low sorbitol level or a high drug content. FTIR investigations supported the antiplasticisation action of paracetamol through the disturbance of sorbitol-starch interactions. Despite this difference, an immediate drug release was generally obtained. This study highlights the interplay between plasticiser and drug in influencing the mechanical and swelling characteristics of rice starch films at varying concentrations.

    Introduction: National Pharmaceutical Regulatory Agency, Ministry of Health Malaysia has received 1018 adverse drug reaction reports related to paracetamol with 1972 adverse events from the year 2000 to February 2015. Serious skin reactions including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis, and acute generalized exanthematous pustulosis may develop as a result of allergic reactions of paracetamol. This study aimed to develop and validate a questionnaire regarding Knowledge, Attitude, and Perception towards Allergic Reactions of Paracetamol (KAP-ARP) among the general population.

    Materials and Methods: Content and face validity of the KAP-ARP were determined by four experts and 20 respondents, respectively. A questionnaire with 36 items, consisting of 16 Knowledge, 9 Attitude, and 11 Perception items, was distributed to 177 respondents. Exploratory factor analysis (EFA) was performed for construct validity. Cronbach's alpha was used to determine the reliability of the questionnaire.

    Results: EFA constructed 13 Knowledge, 8 Attitude, and 8 Perception items. The final KAP-ARP questionnaire is reliable based on its internal consistency reliability (Knowledge: α = 0.78; Attitude: α = 0.63; Perception: α = 0.70).

    Conclusion: A valid and reliable questionnaire that is useful for measuring KAP-ARP among the general population has been developed.

    Objectives: This study was conducted to assess the effect of microwave heating on the preparation of paracetamol cross-linked gelatin matrices by using the design of experiment (DoE) approach and explore the influence of the duration of microwave irradiation, the concentrations of crosslinker, and the amount of sodium bicarbonate (salt) on paracetamol release. These parameters were also compared with those of the matrices prepared via conventional heating.

    Materials and Methods: Twenty gel matrices were prepared with different durations of microwave irradiation, amounts of maize, and concentrations of sodium bicarbonate as suggested by Design Expert (DX®). The percentage drug release, the coefficient of variance (CV) in release, and the mean dissolution time (MDT) were the properties explored in the designed experimentation.

    Results: Target responses were dependent on microwave irradiation time, cross-linker amount, and salt concentration. Classical and microwave heating did not demonstrate statistically significant difference in modifying the percentage of drug released from the matrices. However, the CVs of microwave-assisted formulations were lower than those of the gel matrices prepared via classical heating. Thus, microwave heating produced lesser variations in drug release. The optimized gel matrices demonstrated that the observed percentage of drug release, CV, and MDT were within the prediction interval generated by DX®. The release mechanism of the matrix formulations followed the Peppas-Korsmeyer anomalous transport model.

    Conclusion: The DoE-supported microwave-assisted approach could be applied to optimize the critical factors of drug release with less variation.

    Non-steroidal anti-inflammatory drug, Diclofenac, targeting COX have shown promise in the treatment of Acanthamoeba keratitis, but the underlying mechanisms remain unknown. Using various NSAIDs, Diclofenac sodium, Indomethacin, and Acetaminophen, here we determined the effects of NSAIDs on the biological properties of Acanthamoeba castellanii belonging to the T4 genotype. Using amoebicidal assays, the results revealed that Diclofenac sodium, and Indomethacin affected growth of A. castellanii. In contrast, none of the compounds tested had any effect on the viability of A. castellanii. Importantly, all NSAIDs tested abolished A. castellanii encystation. This is a significant finding as the ability of amoebae to transform into the dormant cyst form presents a significant challenge in the successful treatment of infection. The NSAIDs inhibit production of cyclo-oxegenase, which regulates the synthesis of prostaglandins suggesting that cyclooxygenases (COX-1 and COX-2) and prostaglandins play significant role(s) in Acanthamoeba biology. As NSAIDs are routinely used in the clinical practice, these findings may help design improved preventative strategies and/or of therapeutic value to improve prognosis, when used in combination with other anti-amoebic drugs.

    Medicine is an essential need for many people to treat their illness. Creating awareness among general public regarding medicines use and common illnesses can promote healthy lifestyles among them. The objectives of this study are to determine public knowledge and perception of medicines use and; to explore the pattern of medicines used in the past 3 months. A cross‐sectional survey was carried out among the general public in Pulau Pinang. People who were using medications during the time of the survey or in the last 3 months were invited to participate in the study. Only Malaysians ≥18 years were selected by convenient sampling to participate in the survey. The results of this study showed that most of the respondents were using some sort of medications during the last 3 months. Around 30% did not read the label of the medicines before use. Furthermore, participants had low awareness towards some aspects of medicines use such as the name of generic and brand medicines, overuse of paracetamol or vitamins and their side effects, discontinuation of antibiotics, storing ointments and syrups in refrigerator, and the side effects of medicines registered in Malaysia. Efforts are still needed to increase the awareness of medicines use among the general public. More quantitative studies are needed to understand the factors that may influence public knowledge and perceptions on the use of medicines.

    The protective effect of the ethanol extract of the rhizome of Zingiber officinale Roscoe on acute hepatotoxicity induced by paracetamol (1000 mg/kg) was studied in plasma and hepatic tissue samples obtained from male Sprague-Dawley rats. The ethanol extract was given in oral doses of 200 mg/kg and 300 mg/kg to the rats at 0, 4 and 8 hrs after paracetamol was given orally. The plasma and liver of the rats were subjected to biochemical analysis 24 hrs after hepatotoxicity was induced to determine the levels of superoxide dismutase(SOD), malonaldehyde (MDA) and aspartate transaminase (AST). The results were compared to the rats which were given the antidote N-acetylcysteine (NAC) (500 mg/kg) at 0, 4 and 8 hrs after the paracetamol dose. The results showed that at 200 mg/kg the extract reduced the plasma levels of SOD significantly (p < 0.05) while at a higher dose of 300 mg/kg it reduced plasma SOD, hepatic MDA, serum AST and increased the levels of plasma proteins significantly (p < 0.05). In conclusion, the ethanol extract of Z. officinale showed protective effect against paracetamol induced hepatotoxicity at both dose levels and the protective effect was better at the higher dose.

    This study was carried out to determine the physicochemical properties of carboxymethyl cellulose (CMC) derived from cellulose of palm oil empty fruit bunch (EFB) and its use asa film-coating agent. Samples were prepared at various concentrations and then their physicochemical properties were studied including the viscosity, pH, tensile strength of films, surface properties of the films and dissolution studies on coated tablets. CMC EFB showed lower viscosity than commercial CMC product at the concentration of 1%, 2% and 3% with the values of 44.0cp, 299.9cp, 358.9cp and 90.0cp, 689.9cp, 5569.0cp respectively. The tensile strength of the films for CMC EFB were 7.85MPa, 14.79MPa, 10.36MPa while the commercial CMC exhibited higher values of 21.72MPa, 35.14MPa and 26.9MPa at similar concentration. The scanning electron microscope showed different surface properties of the films for both of them where the commercial CMC is smoother in texture and very transparent unlike its counterpart. However, dissolution studies on paracetamol tablets coated using the samples showed no significant difference (p>0.05) in drug release profile between the two materials. Hence, CMC EFB has a greater potential to be developed as a competitive tablet-coating agent despite the differences in its physicochemical properties.
