    The treatment of chronic myeloid leukaemia (CML) requires quantitative polymerase chain reaction (qPCR) to monitor BCR-ABL1 in International Scale (IS). Some normal subjects were found to harbour BCR-ABL1. We performed a systematic review on normal subjects harbouring BCR-ABL1. A literature search was done on July 16, 2017 using EBSCOhost Research Databases interface and Western Pacific Region Index Medicus. Two authors selected the studies, extracted the data, and evaluated the quality of studies using the modified Appraisal Tool for Cross-Sectional Studies independently. The outcomes were prevalence, level of BCR-ABL1IS, proportion, and time of progression to CML. The initial search returned 4,770 studies. Eleven studies, all having used convenient sampling, were included, with total of 1,360 subjects. Ten studies used qualitative PCR and one used qPCR (not IS). The mean prevalence of M-BCR was 5.9, 15.5, and 15.9% in cord blood/newborns/infants (CB/NB/I) (n = 170), children (n = 90), and adults (n = 454), respectively, while m-BCR was 15, 26.9, and 23.1% in CB/NB/I (n = 786), children (n = 67), and adults (n = 208), respectively. No study reported the proportion and time of progression to CML. Nine studies were graded as moderate quality, one study as poor quality, and one study as unacceptable. The result of the studies could neither be inferred to the general normal population nor compared. Follow-up data were scarce.

    Discoid meniscus is the commonest anatomical aberration of the knee joint, among rare cases such as bilateral separated lateral meniscus, accessory lateral meniscus, partial deficiency of the lateral meniscus and double-layered lateral meniscus. An 11-year-old girl presented with history of chronic pain in her right knee for the last 6 months. The problem disturbed her involvement in the sport activities at school. Clinical examination revealed a clicking sensation on knee extension with lateral joint line tenderness. Magnetic resonance imaging (MRI) of her right knee showed torn posterior horn of lateral meniscus. Arthroscopy examination revealed a discoid meniscus with absence posterior horn. Posterior horn deficient discoid meniscus is a rare form of a congenital meniscus anomaly. We as clinicians believe that the abnormal shaped meniscus may pose a diagnostic challenge clinically and radiologically. Presentation of this case may be beneficial for orthopaedicians in their daily clinical practice.

    INTRODUCTION: Cochlear implantation (CI) in cases with chronic otitis media (COM) was previously contraindicated but recent advances have made it possible.

    OBJECTIVE: To review surgical and audiological outcomes of COM patients that underwent CI.

    MATERIAL AND METHODS: Retrospective review of patients above 18 years old.

    RESULTS: Ten patients with complete data were included. Patients were aged 24-69 years old. Tympanoplasty and mastoidectomy were performed before CI. Imaging was performed to rule out ossifications. Eight patients underwent a standard canal wall up with either cochleostomy or round window approach. One patient had additional canalplasty and tympanoplasty and another one had blind sac procedure respectively. Analysis of the hearing aided level with CI and hearing aid showed significant benefit provided by the CI (Z = 2.803, p = .005).

    DISCUSSION: Creating a dry and safe ear is important prior to CI. Definite hearing improvement is seen in all our cases that helped them to become independent again in their daily life. Hearing aid usage pre-CI might not be important as the hearing aids may continue to cause discharging ears and the benefits of hearing aids in severe to profound hearing loss are very minimal.

    CONCLUSIONS: Cochlear implant is safe and effective in COM patients.

    Tocotrienol is a member of vitamin E family and is well-known for its antioxidant and anti-inflammatory properties. It is also a suppressor of mevalonate pathway responsible for cholesterol and prenylated protein synthesis. This review aimed to discuss the health beneficial effects of tocotrienol, specifically in preventing or treating hyperlipidaemia, diabetes mellitus, osteoporosis and cancer with respect to these properties. Evidence from in vitro, in vivo and human studies has been examined. It is revealed that tocotrienol shows promising effects in preventing or treating the health conditions previously mentioned in in vivo and in vitro models. In some cases, alpha-tocopherol attenuates the biological activity of tocotrienol. Except for its cholesterol-lowering effects, data on the health-promoting effects of tocotrienol in human are limited. As a conclusion, the encouraging results on the health beneficial effects of tocotrienol should motivate researchers to explore its potential use in human.

    Since antiquity, ginger or Zingiber officinale, has been used by humans for medicinal purposes and as spice condiments to enhance flavor in cooking. Ginger contains many phenolic compounds such as gingerol, shogaol and paradol that exhibit antioxidant, anti-tumor and anti-inflammatory properties. The role of ginger and its constituents in ameliorating diseases has been the focus of study in the past two decades by many researchers who provide strong scientific evidence of its health benefit. This review discusses research findings and works devoted to gingerols, the major pungent constituent of ginger, in modulating and targeting signaling pathways with subsequent changes that ameliorate, reverse or prevent chronic diseases in human studies and animal models. The physical, chemical and biological properties of gingerols are also described. The use of ginger and especially gingerols as medicinal food derivative appears to be safe in treating or preventing chronic diseases which will benefit the common population, clinicians, patients, researchers, students and industrialists.

    Biofilms are a natural part of the ecology of the earth. Many biofilms are quite harmful and must be treated or controlled. Other biofilms are beneficial and can be used to help fix serious problems. Biofilms can grow on many different surfaces, including rocks in water, foods, teeth, and various biomedical implants. This bacterial colonization may present the need for additional operations, amputation, or it may even lead to death. The fundamental principles of bacterial cell attachment and biofilm formation are discussed. Biofilms represents a new, wide-open field practice and research that is only going to get hotter with time. Functional organic plasma polymerized coatings are also discussed for their potential as bio-sensitive interfaces, connecting metallic electronic devices with their physiological environments.

    OBJECTIVES: To describe the epidemiology and outcomes of non-traumatic dyspnoea in patients aged 75 years or older presenting to emergency departments (EDs) in the Asia-Pacific region.

    METHODS: A substudy of a prospective interrupted time series cohort study conducted at three time points in EDs in Australia, New Zealand, Singapore, Hong Kong and Malaysia of patients presenting to the ED with dyspnoea as a main symptom. Data were collected over three 72-h periods and included demographics, co-morbidities, mode of arrival, usual medications, ED investigations and treatment, ED diagnosis and disposition, and outcome. The primary outcomes of interest are the epidemiology and outcome of patients aged 75 years or older presenting to the ED with dyspnoea.

    RESULTS: 1097 patients were included. Older patients with dyspnoea made up 1.8% [95% confidence interval (CI) 1.7-1.9%] of ED presentations. The most common diagnoses were heart failure (25.3%), lower respiratory tract infection (25.2%) and chronic obstructive pulmonary disease (17.6%). Hospital ward admission was required for 82.6% (95% CI 80.2-84.7%), with 2.5% (95% CI 1.7-3.6%) requiring intensive care unit (ICU) admission. In-hospital mortality was 7.9% (95% CI 6.3-9.7%). Median length of stay was 5 days (interquartile range 2-8 days).

    CONCLUSION: Older patients with dyspnoea make up a significant proportion of ED case load, and have a high admission rate and significant mortality. Exacerbations or worsening of pre-existing chronic disease account for a large proportion of cases which may be amenable to improved chronic disease management.

    Objectives: The Brief Ageing Perceptions Questionnaire (B-APQ) has five domains that explore views about own ageing. The aim of this study was to validate the B-APQ for use among older adults in Malaysia and to explore socio-demographic variations in ageing self-perceptions.Method: Older adults aged 50 years and above were randomly selected to complete a set of questionnaires. Cronbach's α was used to measure internal consistency, while corrected item-total correlations and correlation with DASS-21 and the CASP-19 scores were employed to assess convergent and discriminant validity. Confirmatory Factor Analysis (CFA) was conducted to confirm the factorial structure of the B-APQ. Difference in self-perceptions of ageing across socio-demographic variables was assessed.Results: Internal consistency for each of the domains was good. Item-total correlations within each domain were strong (>0.6) or very strong (>0.8). Convergent and discriminant validity were supported by significant correlations with DASS-21 depression and CASP-19 scores. CFA results indicated good model fit with the original B-APQ model. Presence of chronic illness also has a significant impact on B-APQ domain scores.Conclusion: The B-APQ is a valid and reliable instrument which can be used to assess self-perceptions of ageing among older Malaysian adults.

    Background: Subjective memory complaints (SMC) are common in the elderly and have been suggested as the first subtle sign of decline which can predict dementia. Cognitive decline is thought to be related to inflammatory processes similarly found in other chronic diseases and conditions such as stroke, heart disease and arthritis. This study aimed to examine the association of SMC with chronic diseases and the profile of these health conditions reported by a group of older adults.Methods: Data from a cross-sectional survey conducted from August 2013 and March 2014 was drawn from 6179 individuals aged 56 years and above. Multivariable logistic regression analyses were used to examine SMC's relationship with individual chronic diseases (asthma, kidney disease, heart disease, stroke, arthritis, hypertension and diabetes) and multimorbidity. Latent class analysis (LCA) was used to identify the profile of health conditions. The effect of SMC was estimated in a multinomial logistic regression as part of the latent class model.Results: SMC was statistically significant in its association with asthma, stroke, heart disease, arthritis and multimorbidity in the fully controlled multivariable logistic regression models. Three health profiles were identified: low comorbidity (n = 4136, low rates in all health conditions), arthritis group (n = 860) and diabetes and hypertension group (n = 1183). SMC was associated with arthritis group (OR = 2.04, 95% CI = 1.51-2.75) and diabetes and hypertension group (OR = 1.22, 95% CI = 1.03-1.46).Conclusion: Adapting a combination of analytical approaches allows a better understanding in the assessment of SMC's relationship with chronic diseases and the patterns of distribution of these health conditions.

    BACKGROUND: Older people use many medications, but combinations of medications used among the oldest old (≥ 80 years) are not commonly reported.

    AIMS: This study aimed to determine common combinations of medications used among women aged 77-96 years and to describe characteristics associated with these combinations.

    METHODS: A cohort study of older women enroled in the Australian Longitudinal Study on Women's Health over a 15-year period was used to determine combinations of medications using latent class analysis. Multinomial logistic regression was used to determine characteristics associated with these combinations.

    RESULTS: The highest medication users during the study were for the cardiovascular (2003: 80.28%; 2017: 85.63%) and nervous (2003: 66.03%; 2017: 75.41%) systems. A 3-class latent model described medication use combinations: class 1: 'Cardiovascular & neurology anatomical group' (27.25%) included participants using medications of the cardiovascular and nervous systems in their later years; class 2: 'Multiple anatomical group' (16.49%) and class 3: 'Antiinfectives & multiple anatomical group' (56.27%). When compared to the reference class (class 1), the risk of participants being in class 3 was slightly higher than being in class 2 if they had > 4 general practitioner visits (RRR 2.37; 95% CI 2.08, 2.71), Department of Veterans Affairs' coverage (RRR 1.59; 95% CI 1.36, 1.86), ≥ 4 chronic diseases (RRR 3.16; 95% CI 2.56, 3.90) and were frail (RRR 1.47; 95% CI 1.27, 1.69).

    CONCLUSION: Identification of combinations of medication use may provide opportunities to develop multimorbidity guidelines and target medication reviews, and may help reduce medication load for older individuals.

    BACKGROUND: A cross-sectional study was carried out to determine the prevalence of complementary and alternative medicine (CAM) use by breast cancer survivors.
    METHODS: A descriptive survey design was developed. Information on socio-demographic characteristics, cancer clinical treatment history, and use of CAM were obtained through a modified self-administered questionnaire from 116 Malay breast cancer survivors aged 21 to 67 years who were 2 years postdiagnosis and currently undergoing follow-up treatment at breast cancer clinics at Hospital Kuala Lumpur and Universiti Kebangsaan Malaysia Medical Centre.
    RESULTS: Data suggest that 64% of the participants were identified as CAM users; dietary supplements were the most common form used, followed by prayer and Malay traditional medicine. Within the wide range of dietary supplements, multivitamins were most often taken followed by spirulina, vitamin C, evening primrose oil, and herbal products. Contrary to other findings, the CAM users were found to be older, had secondary education levels, and were from middle-income households. However, there was no significant difference between CAM users and nonusers in this study. Family members played an important role as the main source of information along with doctors/health care providers, friends, and printed materials/mass media. The reasons participants gave for using CAM were mainly to assist in healing the body's inner strength, to cure cancer, and to reduce stress. Only half of the participants consulted with their physicians regarding the safety of CAM use. The participants began to use CAM while undergoing clinical treatments. Most of the participants used CAM for more than a year. About RM100 to RM149 (31.88 USD to 47.50 USD at press time) were spent monthly on CAM by 32% of the participants. The CAM use was found to be effective and beneficial for patients' disease states, and they were contented with the usage of the CAM therapies. Multivariate analysis revealed that thedecision to use or not to use CAM was not dependent on sociodemographic background or cancer clinical treatment history.
    CONCLUSIONS: CAM was commonly used by breast cancer survivors as a coping mechanism to battle the disease.

    Background Eosinophilic chronic rhinosinusitis (eCRS) is linked with skewed T-helper 2 or immunoglobulin E (IgE)-mediated allergic responses, with differing diagnosis, prognosis, and management to non-eCRS. Objective The association between biomarkers and eCRS was investigated to assess the predictors of eCRS. Methods A cross-sectional study of adult patients with chronic rhinosinusitis (CRS) undergoing endoscopic sinus surgery was conducted. eCRS was defined by histopathological assessment showing >10 eosinophils/high-power field on sinus mucosal biopsy. Blood tests were performed preoperatively and assessed for a full blood count including eosinophils and a white cell count (WCC) as well as biochemical markers of inflammation and atopy including Immunoglobulin E (IgE), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and ImmunoCAP testing for serum-specific IgE. Comparisons between eCRS and non-eCRS patients were performed. Results 345 patients (48.1% female, age 48.72 ± 15.06 years) were recruited, with 206 (59.7%) identified as eCRS, 41% with asthma and 47% CRS with nasal polyps. eCRS patients were more likely to have asthma ( P 0.24 × 109/L), eosinophil ratio (>4.27% of total WCC), and lower ESR when compared with non-eCRS.

    PURPOSE: To evaluate a patient-report instrument for identifying adverse drug events (ADEs) in older populations with multimorbidity in the community setting.

    METHODS: This was a retrospective cohort study of 859 community-dwelling patients aged ≥70 years treated at 15 primary care practices. Patients were asked if they had experienced any of a list of 74 symptoms classified by physiologic system in the previous 6 months and if (1) they believed the symptom to be related to their medication, (2) the symptom had bothered them, (3) they had discussed it with their family physician, and (4) they required hospital care due to the symptom. Self-reported symptoms were independently reviewed by 2 clinicians who determined the likelihood that the symptom was an ADE. Family physician medical records were also reviewed for any report of an ADE.

    RESULTS: The ADE instrument had an accuracy of 75% (95% CI, 77%-79%), a sensitivity of 29% (95% CI, 27%-31%), and a specificity of 93% (95% CI, 92%-94%). Older people who reported a symptom had an increased likelihood of an ADE (positive likelihood ratio [LR+]: 4.22; 95% CI, 3.78-4.72). Antithrombotic agents were the drugs most commonly associated with ADEs. Patients were most bothered by muscle pain or weakness (75%), dizziness or lightheadedness (61%), cough (53%), and unsteadiness while standing (52%). On average, patients reported 39% of ADEs to their physician. Twenty-six (3%) patients attended a hospital outpatient clinic, and 32 (4%) attended an emergency department due to ADEs.

    CONCLUSION: Older community-dwelling patients were often not correct in recognizing ADEs. The ADE instrument demonstrated good predictive value and could be used to differentiate between symptoms of ADEs and chronic disease in the community setting.

    One of the most important drug-related problems in patients with chronic kidney disease (CKD) is medication dosing errors. Many medications and their metabolites are eliminated through the kidney. Thus, adequate renal function is important to avoid toxicity. Patients with renal impairment often have alterations in their pharmacokinetic and pharmacodynamic parameters. The clearance of drugs eliminated primarily by renal filtration is decreased by renal disease. Therefore, special consideration should be taken when these drugs are prescribed to patients with impaired renal function. Despite the importance of dosage adjustment in patients with CKD, such adjustments are sometimes ignored. Physicians and pharmacists can work together to accomplish safe drug prescribing. This task can be complex and require a stepwise approach to ensure effectiveness, minimise further damage and prevent drug nephrotoxicity.

    INTRODUCTION: This article reviews published literature on the usefulness of population-based urinary screening in the Asian paediatric population.

    METHODS: Articles were found in the Medline database using the key words "paediatrics", "urine screening", "proteinuria", "haematuria" and "population". The Asian countries which had carried out population-based urinary screening of the paediatric population included Taiwan, Japan and Korea. One study was found on urinary screening in a select population in Malaysia. Preliminary results of the urinary screening of school children in Singapore are presented and compared with the results found in the above-mentioned countries.

    RESULTS: Overall, the proportion of children found to have urinary abnormalities ranged from less than 0.1% of the population screened to almost 50% of a select cohort referred from the screening programmes for the evaluation of urinary abnormalities. In the pilot Singapore school screening programme, the prevalence of clinically significant proteinuria was 1.25 per 1000 children screened. Multivariate analysis showed that low body weight was associated with a 1.8-fold greater risk for proteinuria. The major cause of haematuria and proteinuria in those studies where renal biopsies were performed was glomerulonephritis. The Taiwanese experience also showed a reduction in the incidence of end-stage renal failure diagnosed in children after the onset of urine screening.

    CONCLUSION: These studies showed that urinary screening programmes in school children allow the early detection of disease. The cost-benefit ratio for specific populations should be determined before the implementation of such programmes.
