    BACKGROUND: Patients with severe psoriasis, namely those requiring phototherapy or systemic treatment, have an increased risk of death. The aim of this study was to determine the prevalence, aetiology and risk factors for mortality among adult patients aged 18 years and above with psoriasis in Malaysia.

    METHODS: This was a retrospective study involving adult patients notified by dermatologists to the Malaysian Psoriasis Registry between July 2007 and December 2013. Data were cross-checked against the National Death Registry. Patients certified dead were identified and the cause of death was analysed. Multivariate analysis using multiple logistic regression were conducted on potential factors associated with higher risk of mortality.

    RESULTS: A total of 419 deaths were identified among the 9775 patients notified. There were four significant risk factors for higher mortality: age>40 years (age 41-60 years old, Odds Ratio (OR) 2.70, 95%CI 1.75, 4.18; age>60 years OR 7.46, 95%CI 4.62, 12.02), male gender (OR 1.72, 95%CI 1.33,2.22), severe psoriasis with body surface area (BSA) >10% (OR 1.52, 95%CI 1.19, 1.96) and presence of at least one cardiovascular co-morbidity (OR 1.67, 95% CI 1.30, 2.14). Among the 301 patients with verifiable causes of death, the leading causes were infection (33.9%), cardiovascular disease (33.6%) and malignancy (15.9%).

    CONCLUSION: Infection was the leading cause of death among psoriasis patients in Malaysia. Although cardiovascular diseases are well-known to cause significant morbidity and mortality among psoriasis patients, the role of infections and malignancy should not be overlooked.

    The incidence of premature multi-vessel coronary artery disease (CAD) is on the rise in Malaysia. The pathogenesis of coronary atherosclerosis is multi-factorial with dyslipidaemia being one such risk factor. Elevated total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglycerides (TG) levels are primarily responsible. We analysed the fasting pre-operative lipid profiles of coronary artery bypass graft (CABG) patients with symptomatic severe premature CAD. A majority of patients had an elevated LDL cholesterol level despite being on a statin. Similarly, no patient with an elevated TG level was prescribed a fibrate. Pre-operative control of known dyslipidaemia was suboptimal in young adults with angiographially proven severe symptomatic CAD. This is either due to subtherapeutic dose prescribing or failure to commence appropriate anti-lipid drugs. Collectively, general practitioners, cardiologists and cardiac surgeons must be more diligent in monitoring lipid profiles in such patients and be more meticulous in prescribing therapeutic doses to achieve target control.

    471 ovarian tumours were available for study from 1980 to 1987. Epidemiological breakdown by race, age and the histological type of the tumours was obtained. The diagnosis of the individual tumours was based on the World Health Organisation (WHO) histological classification of ovarian tumours. There were 324 (68.8%) benigh and 147 (31.2%) malignant tumours. 253 (53.7%) of the tumours were seen in the Malays. The third decade was the peak age for the benigh tumours, and for the malignant tumours, the fourth and fifth decades. 138 (42.6%) of the benign ovarian tumours were cystic teratomas and 45 (30.6%) of the malignant tumours were cystadenocarcinoma.

    A retrospective analysis of 49 patients with 55 liver abscesses evaluated by diagnostic ultrasonography was made. The sonographic appearances were varied and non-specific. 96% of the abscesses were in the right lobe of the liver. Sonographic features which were frequently observed include (a) predominantly hypoechoic internal echotexture (64%) (b) distal sonic enhancement (98%) (c) well-defined margin with an abrupt transition between normal liver parenchyma and lesion (96%) and (d) absence of wall echoes (89%). A combination of these features has considerable diagnostic value. Distal sonic enhancement is of particular diagnostic importance. In equivocal cases the diagnosis can be quickly determined by percutaneous needle aspiration under ultrasound guidance.

    The proliferation of home sharing in the extant marketing and tourism literature has only been accelerated in recent times due to the emergence of the sharing economy. This paper contends that it is now an opportune time to pursue a stock take of existing knowledge in order to guide future marketing and tourism research on home sharing. Therefore, the goal of this paper is to review and propose an agenda for home sharing from a marketing and tourism perspective. Through a framework-based systematic review, this paper offers an organized, retrospective view of the antecedents, decisions, and outcomes (ADO) of home sharing in marketing and tourism. The paper also provides a snapshot on the theories, contexts, and methods (TCM) employed to gain this understanding before concluding with a discussion on the extant knowledge gaps and the ways in which these gaps could be addressed through pertinent ideas for future marketing and tourism research on home sharing.

    AIM: To describe the prevalence and changes in treatment patterns of ranibizumab and photodynamic therapy (PDT) among retinal disease patients who attended the Ophthalmology Clinic in the tertiary care Hospital Selayang from 2010 to 2014.

    METHODS: Study subjects were recruited retrospectively using the Electronic Medical Record (EMR) database software in Hospital Selayang. Demographic data, medical history, diagnostic procedure, treatments and diagnosis of patients were recorded.

    RESULTS: The five-year analysis included 821 patients with a mean age of 65.9±11.73y. Overall, there were a higher number of males (63.1%) and a higher number of Chinese (47.4%) patients. Among the 821 patients, 62.9% received ranibizumab injection followed by 19.2% PDT therapy and 17.9% had ranibizumab combined with PDT therapy. Age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) were the most common retinal eye diseases reported, recording prevalence of 25.0% and 45.6%, respectively. The trend in ranibizumab treatment was reported to increase while PDT showed a decrease in trend from year 2010 to 2014. In terms of treatment, following multiple logistic regression, AMD was associated with the subjects being more likely to have received ranibizumab monotherapy (P<0.001) while PCV was associated with more likely to have received PDT (P<0.001) and PDT combined with ranibizumab therapy (P<0.001).

    CONCLUSION: The tertiary care setting in Malaysia is consistent with management of patients from other countries whereby ranibizumab is the most common treatment given to patients with AMD, while PCV patients most commonly receive PDT and ranibizumab combined with PDT therapy.

    Popliteal artery injury is the most disastrous intraoperative complication during total knee replacement. This study aims to determine the mean distance between the popliteal artery (PA) and the tibial plateau in normal and osteoarthritic patients who underwent Dual Energy CT Angiography (CTA) of the lower limb.
    Materials and Methods: All CTA lower limb examinations from January 2013 to October 2014 were retrospectively reviewed. The distance between the PA the tibial plateau distance and the thickness of popliteus muscle were electronically measured. We used modified Kellgren and Lawrence’s Classification to grade the osteoarthritis in patients who underwent CT examinations regardless of symptoms.
    Results: There were a total of 126 patients who underwent CTA (93 males and 33 females). 54 of them were Malays, 47 Indians, and 24 Chinese. The mean age of patients was 58 years (range 16 to 92). The mean PA-totibial plateau distance was 9.9 mm for the right lower limb (range 2.5 mm to 17.2 mm) and 10.24 mm for the left (range 5.5 mm to 15.4 mm). There were no significant correlations between PA-to-tibial plateau distance with osteoarthritis grade, age, gender, and racial origin (P > 0.05); however, there was a positive
    correlation between PA-to-tibial plateau distances with popliteus muscle thickness (P = 0.000).
    Conclusion: Osteoarthritic condition in the knee does not reduce the popliteal artery to the tibial plateau distance. Hence, a higher osteoarthritic grade does not impose additional risks with regards to popliteal artery to tibial plateau distance, with relatively similar arterial injury risks compared to normal knees.

    INTRODUCTION: The purposes of this review were to appraise the level of evidence of the existing regenerative endodontic therapy (RET) publications, perform a meta-analysis on the survival and healing rates of necrotic immature permanent teeth treated with RET, and run a meta-analysis on the quantitative assessment of the root development of those teeth.

    METHODS: Electronic searches were performed in Web of Science, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane Library databases. Two authors independently screened the titles and abstracts for eligibility. The analyses were performed on the clinical outcomes (ie, survival, healing, and root development) of the procedure.

    RESULTS: Eleven articles were included in the qualitative and quantitative syntheses. Three studies were randomized controlled trials, 6 were prospective cohort studies, and 2 were retrospective cohort studies. The pooled survival and healing rates were 97.3% and 93.0%, respectively. The pooled rates of root lengthening, root thickening, and apical closure were 77.3%, 90.6%, and 79.1%, respectively. However, if 20% radiographic changes were used as a cutoff point, there were only 16.1% root lengthening and 39.8% root thickening.

    CONCLUSIONS: Within the limitations of the present study, it can be concluded that RET yielded high survival and healing rates with a good root development rate. However, clinical meaningful root development after RET was unpredictable.

    BACKGROUND: Antiphospholipid syndrome (APS) is an autoimmune disorder characterised by thrombosis and/or pregnancy morbidity in the presence of antiphospholipid antibodies (aPLs) based on the Sydney criteria. We aimed to explore the clinico-laboratory features and treatment strategies of APS patients retrospectively.
    METHODOLOGY: The medical records of APS patients registered under Hospital Universiti Sains Malaysia (Kelantan state) between 2000 and 2015 were reviewed.
    RESULTS: A total of 17 APS subjects (age 40.7 ± 12.8 years) including 11 primary (64.7%) and six secondary APS (35.3%) patients were identified. The follow-up period was 9.5 ± 6.7 years with male:female ratio of 1.0:4.7. Pregnancy morbidity was the most common clinical manifestation (11/14; 78.6%) followed by recurrent venous thrombosis (10/17; 58.8%). For other clinical features, menorrhagia was the most frequently observed manifestation (4/14; 28.6%) followed by aPLs-associated thrombocytopenia (4/17; 23.5%) and ovarian cyst (3/14; 21.4%). LA and aCL were positive in 94.1% (16/17) and 81.8% (9/11) of the patients, respectively. APTT value (76.7 ± 17.0 sec) was significantly high (p < 0.05). Low intensity warfarin alone was successful to maintain target INR (2.0 - 3.0) and prevent recurrence of thrombosis.
    CONCLUSION: The tendency of pregnancy morbidity in this cohort of Malaysian Kelantanese APS patients was high compared to other previously reported APS cohorts. Low intensity warfarin was successful in preventing recurrence of thrombosis, however, APS women receiving long-term anticoagulants should be monitored for possible occurrence of menorrhagia and ovarian cysts.

    The purpose of this study is to retrospectively report the results of scoliosis patients who underwent chiropractic therapy and to evaluate their outcome by looking at the potential to alter the natural progression of scoliosis after therapy.
    Methods: Retrospective data collection was conducted at a private chiropractic centre in Kuala Lumpur. The data was collected from patients between the ages of 16 to 19 years old. A total of eight patients with 14 scoliotic curvatures (six thoracic, six lumbar and two thoracolumbar), who met the inclusion criteria, were selected as subjects for this study. All subjects received the same chiropractic therapy program. The outcome of the therapy was assessed by measuring the Cobb’s angle on the erect spine as captured on an x-ray. The Cobb’s angle was measured at the first presentation (to establish a baseline) after 6 and 24 months of therapy.
    Results: The mean baseline Cobb’s angle for thoracic, lumbar and thoracolumbar scoliosis were 30.70 ± 19.40, 31.70 ± 12.30 and 25.00 ± 18.40 respectively. After 24 months of chiropractic therapy, there was no discernible effect on the magnitude of the Cobb’s angles on the subjects overall.
    Conclusion: Our study showed no significant reduction in spine curvature in patients with scoliosis using chiropractic therapy after 24 months.

    Objective: To examine the clinical utility of tumor markers in dermatomyositis/polymyositis patients in Taiwan.

    Method: Data were collected retrospectively from the database of Taichung Veterans General Hospital in Taiwan from 1998 to 2014. Patients who fulfilled Bohan and Peter criteria of dermatomyositis/polymyositis were recruited. Serum level of tumor markers including carcinoembryonic antigen, alpha-fetoprotein, carbohydrate antigen 125, carbohydrate antigen 19-9 and carbohydrate antigen 15-3 were measured. The occurrence of malignancies and interstitial lung disease was identified. The association of tumor markers with malignancies and interstitial lung disease was examined using Chi-square test or Fisher's exact test.

    Results: Among the enrolled 151 patients, 98 (64.9%) dermatomyositis and 53 (35.1%) polymyositis, a total of 15 malignancies were detected: breast ductal carcinoma (n = 4), bladder transitional cell carcinoma (n = 2), lung adenocarcinoma (n = 2), cervical intraepithelial neoplasia 3 and papillary squamous cell carcinoma (n = 2), colorectal (colon and rectal adenocarcinoma) (n = 2), uterine adenocarcinoma (n = 1), nasopharyngeal carcinoma (n = 1) and hematological malignancy (myelodysplastic with excess blast cells) (n = 1). Among the patients with malignancies, 13 (86.7%) had dermatomyositis, 2 (13.3%) polymyositis and 3 (20%) interstitial lung disease. The mean duration from dermatomyositis/polymyositis diagnosis to the occurrence of malignancies was 6.05 ± 5.69 years. There was no significant association of raised tumor markers with the occurrence of malignancies (p > 0.085), while a significant association was observed between the elevated levels of carbohydrate antigen 15-3 and the presence of interstitial lung disease (p = 0.006).

    Conclusion: Tumor markers were not useful in malignancy screening or dermatomyositis/polymyositis patients in this tertiary center. The evaluation of the occurrence of malignancy in dermatomyositis/polymyositis patient should include a multidimensional approach. A raised level of carbohydrate antigen 15-3 may be a potential indicator of the presence of interstitial lung disease in dermatomyositis/polymyositis patients.

    Child abuse is as age-old problem which involves physical, emotional and sexual abuse and also the unauthorised administration of drugs to children. The problem does not arise from just a single cause or factor but is multifactorial. One big area is the presence of social situational stresses prior to or during the episodes of abuse. The author has carried out a retrospective study of twenty cases of child abuse investigated by the Department of Social Welfare, Kuala Lumpur from December 1979 to January 1980. This paper describes part of the findings, namely the social situational stresses. The findings are found to be similar to those of other studies, both local and abroad.

    Since the theory of planned behavior (TPB) was proposed by Ajzen in 1985, it has attracted extensive interest and been widely applied worldwide. Although an increasing number of studies have employed the TPB in the domain of environmental science, there have been no attempts to retrospectively analyze existing articles. The current study aimed to holistically understand the application status of the TPB in environmental science from a knowledge domain visualization perspective. A total of 531 journal articles were obtained through the Scopus database to perform a bibliometric analysis and content analysis. The results showed that waste management, green consumption, climate and environment, saving and conservation, and sustainable transportation are the primary research topics; the United States (U.S.), Mainland China, the United Kingdom (UK), and Malaysia are the most productive countries/regions. Moreover, the cross-disciplinary situations, main source journals, and key articles were revealed. Furthermore, the extended factors, integrated theories, major methods, specific groups, and control variables of environmental science research using the TPB were elaborated and integrated into a comprehensive application framework. Constructive criticisms were ultimately discussed. The findings contribute in several ways to help relevant researchers learn about the application of TPB to environmental science and provide new insights and holistic references for further research on environment-related behavior.

    Background: Radial endobronchial ultrasound (R-EBUS) is an effective technique in the diagnosis of peripheral pulmonary lesions (PPL). However, lesion orientation with regards to the radial probe remains an important factor for effective biopsy. "Within" orientation was associated with significantly higher diagnostic yield. Cryobiopsy is a novel technique in obtaining larger tissue samples with the frozen tip allowing biopsy in a 360° direction, thus potentially achieving more effective biopsy in eccentrically and adjacently orientated lesions. We aimed to evaluate the performance and safety of transbronchial cryobiopsy versus forceps biopsy in eccentrically and adjacently orientated R-EBUS lesions.

    Methods: Retrospective review of R-EBUS transbronchial biopsy for PPL over 17 months.

    Results: 114 R-EBUS scans were included for analysis during the study period. Forceps biopsy was performed in 76 (66.7%) cases and cryobiopsy in 38 (33.3%) cases. Baseline demographics and lesion characteristics did not differ between the two groups. Median (interquartile range) lesion size was 3.48 (2.63-4.51) cm. Overall, 41.2% of lesions were of eccentric orientation and 15.8% adjacent orientation; only 43% were concentric in orientation. Overall diagnostic yield was 67.5% (77 out of 114). Orientation remained an important factor affecting diagnostic yield. Transbronchial cryobiopsy significantly increased the diagnostic yield in eccentrically and adjacently orientated lesions to 75.0% (18 out of 24), compared to 48.8% (20 out of 41) obtained via forceps biopsy (p<0.05); but not in concentric lesions. Cryobiopsy was associated with more mild and moderate bleeding complications compared to the forceps biopsy group.

    Conclusions: Transbronchial cryobiopsy under R-EBUS guidance is a safe procedure which potentially increases diagnostic yield in eccentrically and adjacently orientated PPLs.

    The purpose of this study was to assess the tissue
    response of Type 2 diabetic subjects towards non surgical
    periodontal therapy as compared with matched, nondiabetic
    subjects. This was a retrospective, comparative
    study using periodontal case notes of 40 subjects attending
    undergraduates’ periodontal clinics (20 diabetics, 20 nondiabetics),
    who were selected based on the inclusion
    and exclusion criteria. Response towards non surgical
    periodontal therapy was assessed through three clinical
    periodontal parameters, namely plaque score, gingivitis
    score and number of periodontal pocket ≥5mm at the
    baseline and after initial non surgical periodontal therapy.
    Data obtained was then analyzed by SPSS Version 12.
    Both diabetic and non-diabetic subjects showed significant
    improvements (p-value = 0.021; 0.000; 0.001 and 0.010;
    0.014; 0.001) in all three parameters after the therapy.
    However, when comparison was made between the two
    groups, there was no significant difference (p-value = 0.913;
    0.892 and 0.903) in any of the parameters. Periodontal
    conditions improved clinically in both diabetic and nondiabetic
    subjects after non-surgical periodontal therapy.
    Therefore, both groups responded similarly towards the
    therapy and thus it can be postulated that well-controlled
    diabetic status does not have a significant effect on the
    outcome of periodontal therapy.
