    Nasopharnygeal carcinoma is known to be the commonest tumour of the nasopharynx. However, the incidence of nasopharngeal carcinosarcoma is extremely rare. Carcinosarcoma has been reported to be aggressive in nature and therefore early diagnosis and prompt treatment is important. We report a young lady who was diagnosed with nasopharyngeal carcinosarcoma in our centre. She presented with only 2 weeks history of nose block and was noted to have a mass occupying the nasopharynx with neck metastasis. She underwent panendoscope and biopsy with radical radiotherapy.

    INTRODUCTION: The aim of this study was to analyse the clinical characteristics of patients with rheumatoid arthritis receiving biologics therapy and investigate the association between types of biologics and tuberculosis (TB) infections in 13 tertiary hospitals in Malaysia.

    MATERIALS AND METHODS: This was a retrospective study that included all RA patients receiving biologics therapy in 13 tertiary hospitals in Malaysia from January 2008 to December 2018.

    RESULTS: We had 735 RA patients who received biologics therapy. Twenty-one of the 735 patients were diagnosed with TB infection after treatment with biologics. The calculated prevalence of TB infection in RA patients treated with biologics was 2.9% (29 per 1000 patients). Four groups of biologics were used in our patient cohort: monoclonal TNF inhibitors, etanercept, tocilizumab, and rituximab, with monoclonal TNF inhibitors being the most commonly used biologic. The median duration of biologics therapy before the diagnosis of TB was 8 months. 75% of patients had at least one co-morbidity and all patients had at least one ongoing cDMARD therapy at the time of TB diagnosis. More than half of the patients were on steroid therapy with an average prednisolone dose of 5 mg daily.

    CONCLUSION: Although the study population and data were limited, this study illustrates the spectrum of TB infections in RA patients receiving biologics and potential risk factors associated with biologics therapy in Malaysia.

    In this paper we report results of skin prick tests (SPT) using pollen extracts on 200 patients with clinical symptoms of asthma, and results of a parallel study in which pollen was collected and classified over a period of 18 months. The patients were outpatients from the University Hospital in Kuala Lumpur, Malaysia, while the pollen grains were collected with a spore trap placed in the campus of the University of Malaya, approximately one kilometer from the University Hospital. Pollen extracts of 3 grasses (Bahia, Bermuda, rough pigweed) and 2 flowering trees, Acacia and Melaleuca, were used in the SPT. Of the 29.5% asthmatics with positive SPT reactions, 21.5% were to one or more of the grass pollens, 21.5% to Acacia and 7.5% to Melaleuca pollen. Acacia and Bermuda grass extracts were the most allergenic, which agreed with results of the pollen collection which showed grass and Acacia pollen grains to be the two most commonly found pollens.

    This study aims to evaluate the practice of adjuvant chemotherapy in colorectal cancer at the Institute of Radiotherapy and Oncology, Hospital Kuala Lumpur. A retrospective analysis of 320 patients' records from 1986 to 1994 was carried out. Adjuvant chemotherapy was given to 98 patients. Cancers of the rectum and sigmoid colon constituted over 60% of the patients. All the regimes used were 5-fluorouracil-based. The oral route was the most commonly used (55.1%). Toxicity was seldom the reason for stopping treatment (2%). The adjuvant treatment employed has been tolerable while the survival was comparable with other centres.

    Ambulatory or day care surgery is still in its infancy in this part of the world. Our newly built university affiliated hospital started its Day Surgery Centre in February 1998. It is the first multidisciplinary ambulatory surgery centre in a teaching hospital in the country. It caters for Orthopaedic surgery, Urology, Plastic surgery, Otorhinolaryngology, General surgery, Paediatric surgery and Ophthalmology. We have done 2,604 cases and our unanticipated admission rate is less than 2%. There has been no major morbidity or mortality. The problems of setting up a multidisciplinary ambulatory centre in a teaching hospital are discussed.

    BACKGROUND AND PURPOSE: This study aimed to evaluate an accelerated dispensing course for graduate entry (GE) pharmacy students with prior science-related degrees to join undergraduate (UG) students in year three of the Monash Pharmacy degree.

    EDUCATIONAL ACTIVITY AND SETTING: A one day accelerated dispensing course using MyDispense software was delivered to 59 GE students. The accelerated dispensing course was identical to the standard three-week dispensing course delivered to UG students. The same assessment of dispensing skills was conducted after course completion for both UG and GE students and included dispensing four prescriptions of varying difficulty. The assessment scores of the UG and GE students were compared. Perception data from the accelerated course were also collected.

    FINDINGS: The accelerated dispensing curriculum was well received by students. They found the simulation relevant to practice, easy to navigate, and helpful for preparing them for assessment. Overall, 5.1% of GE students failed the assessment, which was lower than the 32.6% failure rate in the UG cohort. Comparison of assessment grades between UG and GE students showed no notable disadvantage to attainment of learning outcomes with the accelerated curriculum. However, UG students were more likely to provide unsafe instructions compared to GE students in their labeling for three out of four prescriptions.

    SUMMARY: An accelerated dispensing curriculum can be effectively delivered to mature learners with a prior science-related degree as no notable deficiencies were identified when comparing the assessment results of GE students against UG students when both student cohorts undertook the same dispensing assessment.

    In Malaysia, it is a common belief among health care workers that females and Indians have lower pain threshold. This experience, although based on anecdotal experience in the healthcare setting, does not allow differentiation between pain tolerance, and pain expression. To determine whether there is a difference in the tolerance to pain between the three main ethnic groups, namely the Malays, Chinese and Indians as well as between males and females. This was a prospective study, using a laboratory pain model (ischaemic pain tolerance) to determine the pain tolerance of 152 IMU medical students. The mean age of the students was 21.8 years (range 18-29 years). All of them were unmarried. The median of ischaemic pain tolerance for Malays, Chinese and Indians were 639s, 695s and 613s respectively (p = 0.779). However, statistically significant difference in ischaemic pain tolerance for males and females Indian students were observed. Possible ethnic difference in pain tolerance in casual observation is not verified by this laboratory pain model. Difference in pain tolerance between genders is shown only for Indians.

    OBJECTIVES: To describe the implementation and assess whether an objective structured clinical examination (OSCE) is a viable assessment tool for testing Antimicrobial Stewardship (AMS) principles.

    METHODS: A three-station OSCE set in a hospital and community pharmacy was designed and mapped to the World Health Organisation's AMS intervention practical guide. This OSCE comprised 39 unique cases and was implemented across two campuses (Malaysia and Australia) at one institute. Stations were 8 min long and consisted of problem-solving and applying AMS principles to drug therapy management (Station 1), counselling on key antimicrobials (Station 2) or managing infectious diseases in primary care (Station 3). Primary outcome measure to assess viability was the proportion of students who were able to pass each case.

    KEY FINDINGS: Other than three cases with pass rates of 50, 52.8 and 66. 7%, all cases had pass rates of 75% or more. Students were most confident with referral to medical practitioner cases and switching from intravenous to oral or empirical to directed therapy.

    CONCLUSIONS: An AMS-based OSCE is a viable assessment tool in pharmacy education. Further research should explore whether similar assessments can help improve students' confidence at recognising opportunities for AMS intervention in the workplace.

    INTRODUCTION: Attitudes of speech-language pathologists (SLPs) toward stuttering play an important role in managing stuttering cases. Yet, such studies had not been studied in Malaysia, a country that is still developing the profession of speech-language pathology. This study aimed to explore the attitudes of Malaysian SLPs and speech-language pathology students toward stuttering.

    METHODS: A total of 50 SLPs and 67 speech-language pathology students completed the Clinician Attitudes Towards Stuttering (CATS) inventory. There were eight domains of attitudes toward stuttering: (a) etiology, (b) early intervention, (c) therapeutic efficacy, (d) personalities of PWS, (e) clinician expertise and roles, (f) teacher/counsellor roles and client/public reactions, (g) therapy strategies, and (h) parent attitudes. Descriptive data were presented and Multivariate Analysis of Variance was conducted to examine the effects of clinical certification on the eight domains of attitudes toward stuttering.

    RESULTS: Participants who possessed a clinical certification were more accepting toward the personalities of people who stutter (PWS) and therapy strategies. On the other hand, participants without a clinical certification were more accepting toward clinician expertise and roles.

    CONCLUSIONS: Current curriculum and professional training should be re-evaluated to remediate less accepting stereotypes held by SLPs and students toward PWS and to enhance essential skills such as counselling.

    In Southeast Asia, cervical cancer is the second most common cancer in women. Low coverage for cervical cancer screening (CCS) becomes a roadblock to disease detection and treatment. Existing reviews on CCS have limited insights into the barriers and facilitators for SEA. Hence, this study aims to identify key barriers and facilitators among women living in SEA. A systematic literature review was conducted on Pubmed, Embase, PsycINFO, CINAHL, and SCOPUS. Primary qualitative and quantitative studies published in English that reported barriers and facilitators to CCS were included. The Mix Methods Appraisal Tool was used for the quality assessment of the included studies. Among the 93 included studies, pap smears (73.1%) were the most common screening modality. A majority of the studies were from Malaysia (35.5%). No studies were from Timor-Leste and the Philippines. The most common barriers were embarrassment (number of articles, n = 33), time constraints (n = 27), and poor knowledge of screening (n = 27). The most common facilitators were related to age (n = 21), receiving advice from healthcare workers (n = 17), and education status (n = 11). Findings from this review may inform health policy makers in developing effective cervical cancer screening programs in SEA countries.

    AIM: This study is conducted to compare the pharmacokinetic profiles of two fixed dose combination of metformin/glibenclamide tablets (500mg/5 mg per tablet).

    MATERIALS AND METHODS: This is a single-center, single-dose, open-label, randomized, 2-treatment, 2-sequence and 2- period crossover study with a washout period of 7 days. All 28 adult male subjects were required to fast for at least 10 hours prior to drug administration and they were given access to water ad libitum during this period. Thirty minutes prior to dosing, all subjects were served with a standardized high-fat and high-calorie breakfast with a total calorie of 1000 kcal which was in accordance to the EMA Guideline on the Investigation of Bioequivalence. Subsequently, subjects were administered either the test or reference preparation with 240mL of plain water in the first trial period. During the second trial period, they received the alternate preparation. Plasma levels of glibenclamide and metformin were analysed separately using two different high performance liquid chromatography methods.

    RESULTS: The 90% confidence interval (CI) for the ratio of the AUC0-t, AUC0-∞, and Cmax of the test preparation over those of the reference preparation were 0.9693-1.0739, 0.9598- 1.0561 and 0.9220 - 1.0642 respectively. Throughout the study period, no serious drug reaction was observed. However, a total of 26 adverse events (AE)/side effects were reported, including 24 that were definitely related to the study drugs, namely giddiness (n=17), while diarrheoa (n=3), headache (n=2) and excessive hunger (n=2) were less commonly reported by the subjects.

    CONCLUSION: It can be concluded that the test preparation is bioequivalent to the reference preparation.

    Brain size varies greatly at all taxonomic levels. Feeding ecology, life history and sexual selection have been proposed as key components in generating contemporary diversity in brain size across vertebrates. Analyses of brain size evolution have, however, been limited to lineages where males predominantly compete for mating and females choose mates. Here, we present the first original data set of brain sizes in pipefishes and seahorses (Syngnathidae) a group in which intense female mating competition occurs in many species. After controlling for the effect of shared ancestry and overall body size, brain size was positively correlated with relative snout length. Moreover, we found that females, on average, had 4.3% heavier brains than males and that polyandrous species demonstrated more pronounced (11.7%) female-biased brain size dimorphism. Our results suggest that adaptations for feeding on mobile prey items and sexual selection in females are important factors in brain size evolution of pipefishes and seahorses. Most importantly, our study supports the idea that sexual selection plays a major role in brain size evolution, regardless of on which sex sexual selection acts stronger.

    INTRODUCTION: There has been an observed number of readmissions after an index COVID-19 admission, including admissions after an initial home quarantine. The purpose of this study was to identify the clinical characteristics and outcomes of COVID-19 patients who were readmitted or admitted after an initial home quarantine between 21 and 90 days of illness.

    MATERIALS AND METHODS: This was a single-centre retrospective cohort study comprising patients admitted to a state hospital in Selangor, Malaysia, between August and October 2021. The demographic data, clinical characteristics, presenting complaints, laboratory tests, organ dysfunction, use of invasive ventilation, intensive care unit (ICU) admissions, length of hospitalisation and mortality were collected and analysed.

    RESULTS: The analysis involved a total of 195 cases. More than a quarter of the cases (52 [26.7%]) were related to the initial COVID-19 infection. Nine cases (4.6%) required mechanical ventilation, while eight cases (4.1%) were admitted to the ICU. The overall mortality was 17 cases (8.7%). Surviving patients were younger (49.5 vs. 58.4 years), less likely to have diabetes mellitus (48.3% vs. 82.4%), or chronic kidney disease (12.9% vs. 41.2%); had higher levels of admission haemoglobin (12.6 vs. 9.1g/dL) and albumin (33.0 vs. 21.0g/L); lower white blood cells (10.2 vs. 13.0 × 109/L), creatinine (81.2 vs. 151.9μmol/L) and C-reactive protein (18.2 vs. 135.0mg/L) at admission; less likely to have MI (6.7% vs. 23.5%), sepsis (3.4% vs. 47.1%), or acute kidney injury (3.4% vs. 17.6%) and organ dysfunction (25.3% vs. 94.1%).

    CONCLUSION: Approximately a quarter of patients were admitted or readmitted due to direct COVID-19 complications between 21 and 90 days of illness. The baseline oxygen requirements at admission were independently associated with mortality, invasive mechanical ventilation and ICU admissions. Further research is needed to establish a risk model for patients returning to a hospital to predict their risk of post-COVID complications.

    BACKGROUND: Chikungunya is an arboviral disease transmitted by Aedes aegypti and Aedes albopictus mosquitoes with a growing global burden linked to climate change and globalisation. We aimed to estimate chikungunya seroprevalence, force of infection (FOI), and prevalence of related chronic disability and hospital admissions in endemic and epidemic settings.

    METHODS: In this systematic review, meta-analysis, and modelling study, we searched PubMed, Ovid, and Web of Science for articles published from database inception until Sept 26, 2022, for prospective and retrospective cross-sectional studies that addressed serological chikungunya virus infection in any geographical region, age group, and population subgroup and for longitudinal prospective and retrospective cohort studies with data on chronic chikungunya or hospital admissions in people with chikungunya. We did a systematic review of studies on chikungunya seroprevalence and fitted catalytic models to each survey to estimate location-specific FOI (ie, the rate at which susceptible individuals acquire chikungunya infection). We performed a meta-analysis to estimate the proportion of symptomatic patients with laboratory-confirmed chikungunya who had chronic chikungunya or were admitted to hospital following infection. We used a random-effects model to assess the relationship between chronic sequelae and follow-up length using linear regression. The systematic review protocol is registered online on PROSPERO, CRD42022363102.

    FINDINGS: We identified 60 studies with data on seroprevalence and chronic chikungunya symptoms done across 76 locations in 38 countries, and classified 17 (22%) of 76 locations as endemic settings and 59 (78%) as epidemic settings. The global long-term median annual FOI was 0·007 (95% uncertainty interval [UI] 0·003-0·010) and varied from 0·0001 (0·00004-0·0002) to 0·113 (0·07-0·20). The highest estimated median seroprevalence at age 10 years was in south Asia (8·0% [95% UI 6·5-9·6]), followed by Latin America and the Caribbean (7·8% [4·9-14·6]), whereas median seroprevalence was lowest in the Middle East (1·0% [0·5-1·9]). We estimated that 51% (95% CI 45-58) of people with laboratory-confirmed symptomatic chikungunya had chronic disability after infection and 4% (3-5) were admitted to hospital following infection.

    INTERPRETATION: We inferred subnational heterogeneity in long-term average annual FOI and transmission dynamics and identified both endemic and epidemic settings across different countries. Brazil, Ethiopia, Malaysia, and India included both endemic and epidemic settings. Long-term average annual FOI was higher in epidemic settings than endemic settings. However, long-term cumulative incidence of chikungunya can be similar between large outbreaks in epidemic settings with a high FOI and endemic settings with a relatively low FOI.

    BACKGROUND: The utilization of vitamins and dietary supplements (DSs) among consumers in Malaysia has seen a notable increase. However, there is limited research available on how pharmacists in Eastern countries manage the provision of these products.

    OBJECTIVE: This study aims to assess the knowledge, attitudes, and practices of community pharmacists in Malaysia regarding the provision of counselling services on vitamins and DSs. The findings will inform education strategies in this area.

    METHODS: A cross-sectional quantitative study was conducted from February to April 2022 using a validated online-based questionnaire. The survey was distributed to community pharmacists across Malaysia through social media channels. t-test and ANOVA test were used for data analysis.

    RESULTS: Among the 260 participants, 73.5% were categorized as having average product knowledge. Key concerns included a lack of knowledge about the indications of new products and when to discontinue their use. Regarding dosing in specific patient groups, 33.5% of pharmacists only occasionally consulted references and primarily relied on product labels. Furthermore, 29% of pharmacists believed it was unnecessary to refer patients to doctors when they experienced ongoing symptoms while taking vitamins or DSs. Interestingly, 44.6% of pharmacists believed there was a correlation between the efficacy of vitamins and their price, often recommending more expensive brands despite similar content.

    CONCLUSION: There is an opportunity to enhance the knowledge of pharmacists in Malaysia regarding vitamins and DSs. Education interventions should focus on areas such as dosing for specific patient groups, when to discontinue products, understanding new products, evidence-based efficacy of products for specific conditions, and providing a framework for appropriate referral to support pharmacists in their practice.

    Hydroxychloroquine (HCQ) is the first-line systemic treatment for cutaneous lupus erythematosus (CLE). Whole blood HCQ concentration (WBHCQ) was found to correlate with CLE severity among Caucasians. However, studies on Asians are scarce. We aim to explore the relationship of WBHCQ with CLE disease activity among multi-racial Malaysians and the factors associated with WBHCQ. A cross-sectional study targeting patients with CLE was conducted from 1 June till 30 November 2019. Disease activity was assessed using Cutaneous Lupus Erythematosus Disease Area and Severity Index - Activity Score (CLASI-AS). Blood was analyzed for WBHCQ concentration using a high-performance liquid chromatography technique. Statistical analysis was done using R studio version 1.2.1335. A total of 88 subjects (male : female, 4.5:1) with a median age of 41 years old were recruited. The median duration CLE was 5 years. The majority had acute cutaneous lupus (n = 45, 51.1%). The median WBHCQ was 946.8 ng/mL. Indians were found to have the highest WBHCQ (median ± interquartile range [IQR], 1515.4 ± 1494.8 ng/mL). Males had a lower WBHCQ (median ± IQR, 733.5 ± 573.8 ng/mL) than females (995.5 ± 925.1 ng/mL). However, no statistically significant association between race and sex with WBHCQ was demonstrable (p = 0.247, p = 0.066). No correlation was demonstrated between WBHCQ and CLASI-AS (r = -0.02, p = 0.851). A positive correlation was found between HCQ dosage (ideal bodyweight) and WBHCQ (r = 0.24, p = 0.027). No other factors were found associated with WBHCQ. Indians and females were observed to have higher WBCHQ; however, no significant correlation was identified. Further study is required to confirm the finding.

    The displaced supracondylar fracture of the humerus in children (Gartland type 3) is a most challenging injury to treat. There is controversy regarding the initial treatment either closed manipulation and splint immobilization or open reduction and internal fixation. This is a retrospective study comparing two groups of patients with displaced supracondylar fracture of the humerus (Gattland 3) treated in the Orthopaedic Unit, Universiti Kebangsaan Malaysia. The first group, 13 patients treated with closed reduction and splint immobilization and a second group, 15 patients treated with open reduction and internal fixation as initial definitive treatment. The results showed a high failure rate of closed reduction and splint immobilization. This was due to difficulty in reduction, loss of reduction post operatively or during follow-up. Open reduction and internal fixation was more advantages with reduced hospitalization time, fewer complications, more stable fixation and better anatomical reduction with minimal complications for type 3 supracondylar fracture of humerus. We would recommend that all Gartland 3 supracondylar fracture of the humerus be treated with open reduction and two K-wire fixation.

    Drug eruptions from indeginous medicine is often difficult to diagnosis and confirm. It is known that a number of these now supplied by bomohs and Chinese sinsehs contain known drugs and are dispensed as tablets and capsules. We report 3 cases of adverse drug eruption to "Jamu", a Malay herb. A particular brand, "Jamu Indonesia, Toko Air Pancur", from Johor Bahru, Malaysia, is especially recommended for "sakit pinggang" or backache. The cases occurred between January and February 1985, and all had taken brown kidney shaped tablets. The adverse reactions were moderately severe. Two had erythroderma with hepatitis, and one, Steven Johnson Syndrome. Analysis of this jamu for analgesics led to the discovery of adulteration with phenylbutazone and diazepam. Records from local cases from 1974-1984 showed that 8 other patients, all Chinese had adverse cutaneous eruptions from phenylbutazone, oxybutazone and propyphenazone. The skin manifestations were erythroderma (2 cases), vasculitis (2 cases) and toxic epidermal necrolysis (4 cases). Those with toxic epidermal necrolysis had 100% mortality.

    Local Thai and imported Malaysian beef in southern Thailand area carry
    several Shiga toxin-producing Escherichia coli (STEC) serotypes. STEC O104 is an
    important pathogen capable of causing outbreaks with considerable morbidity
    and mortality. This study investigated the presence of E. coli O104 from local Thai
    and imported Malaysian beef obtained from markets in Hat Yai City, Songkhla
    Province during August 2015 - February 2016. Thirty-one E. coli O104 strains
    were isolated from 12 beef samples (16% and 23% Thai and imported Malaysian,
    respectively). Thirty strains possessed aggA (coding for a major component of
    AAF/I fimbriae), a gene associated with enteroaggregative E. coli (EAEC) pathotype,
    and all strains carried fimH (encoding Type 1 fimbriae). Thirty strains
    belonged to phylogenetic group B1 and one strain (from Malaysian beef) to group
    A. Agglutination of yeast cells was observed among 29 E. coli O104 strains. Investigation
    of stx2 phage occupancy loci demonstrated that sbcB was occupied in 12
    strains. Antimicrobial susceptibility assay revealed that 7 strains were resistant
    to at least one antimicrobial agent and two were multi-drug resistant. One strain
    carried extended spectrum β-lactamase gene blaCTX-M and three carried blaTEM. PFGE-generated DNA profiling showed identical DNA pattern between that of
    one EAEC O104 strain from Thai beef and another from Malaysian beef, indicating
    that these two strains originated from the same clone. This is the first report
    in Thailand describing the presence of EAEC O104 from both Thai and imported
    Malaysian beef and their transfer between both countries. Thorough surveillance
    of this pathogen in fresh meats and vegetables should help to prevent any possible
    outbreak of E. coli O104.
