    Upon reviewing the literature, the prevalence of many systemic conditions such as diabetes,
    hypertension, asthma and rheumatoid arthritis were reported to be high in Saudi Arabia. The relationship of these
    conditions with tooth loss among Saudi population was not investigated. Therefore, the aim of the present study
    is to explore the relationship between tooth loss and most common medical conditions among Saudi dental
    patient. The study participants were 250 patients who were randomly selected from the College of Dentistry
    database of King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in Riyadh, Saudi Arabia.
    Participants were requested to answer self-administered questionnaires related to their demographic as well as
    general health questions concerned to the presence of systemic medical conditions. Missing teeth were
    determined after examining the orthopantogram radiographs and reviewing the Romexis and SALUD databases.
    Descriptive statistics, independent t-test and linear multiple regression model were performed using SPSS
    software. The mean number of missing teeth among the study population was 5.8 teeth per person. The mean
    number of missing teeth was higher among subjects with diabetes, hypertension, rheumatoid arthritis,
    cardiovascular diseases, or osteoporosis compared to healthy individuals. A multiple linear regression analysis
    model revealed that diabetes, hypertension and rheumatoid were significant predictors of missing teeth among
    Saudi population. These results highlight the importance of the effect of medical conditions on oral health.

    Pes anserine syndrome is a cause of inferomedial knee pain. It occurs in patients with diabetes mellitus, osteoarthritis, rheumatoid arthritis and in overweight patients. It is a challenge to identify the causes of knee pain following knee replacement surgery. We present a case report of pes anserine syndrome in a 79-year-old female who had undergone knee arthroplasty 13 years prior. She was pain free until one year ago when her knee pain resurfaced without any symptoms of infection or history of trauma. She was successfully treated with a combination of stretching exercise and steroid local steroid injection. We want to highlight that such common condition as pes anserine syndrome, could occur in total knee arthroplasty, and should be considered as one of the possible diagnosis.

    Family Physician, 2003;12(1):33-34.
    Musculoskeletal complaints are one of the most common presenting symptoms to primary care physicians. However, in Malaysia, there has been no prospective survey to look at this problem. This was a descriptive study to look at the prevalence of non-traumatic musculoskeletal complaints presenting to the primary care clinic at University Malaya Medical Center, Kuala Lumpur. Over a 3-week period, there were 408/4201 patients (9.7%) with non-traumatic musculoskeletal disorders. The most common regional problem was backache and the most commonly made diagnosis was non-specific musculoskeletal pain. In conclusion, musculoskeletal disorders form a significant proportion of primary care consultations and thus should be included in the curriculum for the primary care physician training. Keywords: musculoskeletal disorders, arthritis, primary care

    Malays Fam Physician, 2020;15(1):30-38.
    PMID: 32284802
    Objective: To assess the prevalence and social and health correlates of falls and fall risk in a sample of community-dwelling and institutionalized older Indonesians.

    Methods: This cross-sectional study was conducted July-August 2018 in three regions in Indonesia. Adults aged 60 years and above (n=427) were recruited via random sampling from community clinics and public and private elderly homes. They responded to interview-administered questions and provided measurements on sociodemographics and various health variables, including falls and fall risk. Fall risk was assessed with the STEADI (Stopping Elderly Accidents, Deaths, & Injuries) screen. Multivariable logistic regression was conducted to estimate associations with fall and fall risk.

    Results: In the year immediately preceding the study, 29.0% of participants had suffered a fall. Approximately one-third of women (31.1%) and one-fifth of men (20.4%) reported a fall in the past year, and 25.4% of community dwellers and 32.7% of institutionalized older adults had fallen. The overall proportion of fall risk was 45.4%, 49.0% among women, 38.0% among men, 50.5% in the institutionalized setting, and 40.4% in the community setting. In adjusted logistic regression analysis, older age (OR: 1.89, CI: 1.06, 3.37), private elderly home setting (OR:2.04, CI: 1.10, 3.78), and being female (OR: 0.49, CI: 0.30, 0.82) were associated with falls in the preceding 12 months. Older age (80-102 years) (OR: 2.55, CI: 1.46, 4.46), private elderly home residence (OR: 2.24, CI: 1.19, 4.21), lack of education (OR: 0.51, CI: 0.28, 0.93), memory problems (OR: 1.81, CI: 1.09, 2.99), and arthritis (OR: 2.97, CI: 1.26, 7.00) were associated with fall risk by the STEADI screen. In stratified analysis by setting, being female (OR: 0.49, CI: 0.25, 0.95) and living in urban areas (OR: 1.97, CI: 1.03, 3.76) were associated with falls in the institutionalized setting, and having near vision problems (OR: 2.32, CI: 1.09, 4.93) was associated with falls in the community setting. Older age (OR: 2.87, CI: 1.36, 6.07) was associated with fall risk in the institutionalized setting, and rural residence (OR: 0.37, CI: 0.15, 0.93) and having a joint disorder or arthritis (OR: 4.82, CI: 1.28, 16.61) were associated with fall risk in the community setting.

    Conclusion: A high proportion of older adults in community and institutional care in Indonesia have fallen or were at risk of falling in the preceding 12 months. Health variables for fall and fall risk were identified for the population overall and for specific populations in the home care and community setting that could help in designing fall-prevention strategies.

  6. Fulltext Chronic Inflammatory Diseases at Secondary Sites Ensuing Urogenital or Pulmonary Chlamydia Infections
    Cheok YY, Lee CYQ, Cheong HC, Looi CY, Wong WF
    Microorganisms, 2020 Jan 17;8(1).
    PMID: 31963395 DOI: 10.3390/microorganisms8010127
    Chlamydia trachomatis and C. pneumoniae are members of the Chlamydiaceae family of obligate intracellular bacteria. The former causes diseases predominantly at the mucosal epithelial layer of the urogenital or eye, leading to pelvic inflammatory diseases or blindness; while the latter is a major causative agent for pulmonary infection. On top of these well-described diseases at the respective primary infection sites, Chlamydia are notoriously known to migrate and cause pathologies at remote sites of a host. One such example is the sexually acquired reactive arthritis that often occurs at few weeks after genital C. trachomatis infection. C. pneumoniae, on the other hand, has been implicated in an extensive list of chronic inflammatory diseases which include atherosclerosis, multiple sclerosis, Alzheimer's disease, asthma, and primary biliary cirrhosis. This review summarizes the Chlamydia infection associated diseases at the secondary sites of infection, and describes the potential mechanisms involved in the disease migration and pathogenesis.

    Chan EWC, Wong SK, Chan HT
    J Integr Med, 2018 05;16(3):147-152.
    PMID: 29559215 DOI: 10.1016/j.joim.2018.03.001
    This short review provides an update of the anticancer and anti-inflammatory properties of casticin from Vitex species. Casticin is a polymethylflavone with three rings, an orthocatechol moiety, a double bond, two hydroxyl groups and four methoxyl groups. Casticin has been isolated from various tissues of plants in the Vitex genus: fruits and leaves of V. trifolia, aerial parts and seeds of V. agnus-castus and leaves of V. negundo. Studies have reported the antiproliferative and apoptotic activities of casticin from Vitex species. The compound is effective against many cancer cell lines via different molecular mechanisms. Studies have also affirmed the anti-inflammatory properties of casticin, with several molecular mechanisms identified. Other pharmacological properties include anti-asthmatic, tracheospasmolytic, analgesic, antihyperprolactinemia, immunomodulatory, opioidergic, oestrogenic, anti-angiogenic, antiglioma, lung injury protection, rheumatoid arthritis amelioration and liver fibrosis attenuation activities. Clinical trials and commercial use of the casticin-rich fruit extract of V. agnus-castus among women with premenstrual syndrome were briefly discussed.

    PMID: 23634174 DOI: 10.1155/2013/846740
    Andrographis paniculata (Burm. F) Nees, generally known as "king of bitters," is an herbaceous plant in the family Acanthaceae. In China, India, Thailand, and Malaysia, this plant has been widely used for treating sore throat, flu, and upper respiratory tract infections. Andrographolide, a major bioactive chemical constituent of the plant, has shown anticancer potential in various investigations. Andrographolide and its derivatives have anti-inflammatory effects in experimental models asthma, stroke, and arthritis. In recent years, pharmaceutical chemists have synthesized numerous andrographolide derivatives, which exhibit essential pharmacological activities such as those that are anti-inflammatory, antibacterial, antitumor, antidiabetic, anti-HIV, antifeedant, and antiviral. However, what is noteworthy about this paper is summarizing the effects of andrographolide against cardiovascular disease, platelet activation, infertility, and NF- κ B activation. Therefore, this paper is intended to provide evidence reported in relevant literature on qualitative research to assist scientists in isolating and characterizing bioactive compounds.

    Biomed Pharmacother, 2014 Sep;68(7):881-5.
    PMID: 25194446 DOI: 10.1016/j.biopha.2014.07.017
    Rheumatoid arthritis in HIV patients undergoing HAART is associated with increased risk of side effect. Elevation of uric acid (UA) is important in tissue damage, deposition of crystal in joints leads to the development of rheumatoid arthritis in the HAART complaint group. This study was carried out to investigate the relationship of uric acid, RA factor, ANA, ESR, cystatin C, urea and creatinine in the HAART complaint group. Moreover; the ratio of uric acid/cystatin C, uric acid/urea and uric acid/creatinine were also studied. To analyze the progression of HIV, the immunological parameters were correlated with uric acid. Our result showed a statistically high significant increase in uric acid, RA factor, ANA, ESR, cystatin C, urea and creatinine in the HAART complaint group when compared to HAART non-complaint group, early stage and control. The ratio of uric acid/cystatin C, uric acid/urea, uric acid/creatinine were significantly increased in the HAART complaint group. Statistically significant positive correlation was observed between uric acid and cystatin C, urea, creatinine, absolute CD4 and CD8 count. The increased level of uric acid, RA factor, ANA, ESR, cystatin C and increased ratio of uric acid/cystatin C in the HAART complaint group might conclude the mechanism underlying the increased risk for rheumatoid arthritis in the HAART complaint group which may relate to the combined effects of low-grade inflammation and renal dysfunction.

    PMID: 25114906 DOI: 10.1155/2014/539540
    Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory disease primarily involving inflammation of the joints. Although the management of the disease has advanced significantly in the past three decades, there is still no cure for RA. The aim of this study was to determine the therapeutic efficacy of δ-tocotrienol, in the rat model of collagen-induced arthritis (CIA). Arthritis was induced by intradermal injection of collagen type II emulsified in complete Freund's adjuvant. CIA rats were orally treated with δ-tocotrienol (10 mg/kg) or glucosamine hydrochloride (300 mg/kg) from day 25 to 50. Efficacy was assessed based on the ability to reduce paw edema, histopathological changes, suppression of collagen-specific T-cells, and a reduction in C-reactive protein (CRP) levels. It was established that δ-tocotrienol had the most significant impact in lowering paw edema when compared to glucosamine treatment. Paw edema changes correlated well with histopathological analysis where there was a significant reversal of changes in groups treated with δ-tocotrienol. The results suggest that δ-tocotrienol is efficient in amelioration of collagen-induced arthritis. Vitamin E delta-tocotrienol may be of therapeutic value against rheumatoid arthritis.

    ScientificWorldJournal, 2014;2014:823763.
    PMID: 24971392 DOI: 10.1155/2014/823763
    BACKGROUND: The aim of this study was to determine the risk factors of MTX-associated nonalcoholic fatty liver disease (NAFLD) with transaminitis in a cohort of rheumatoid arthritis (RA) patients from Singapore.
    METHODS: Patients who developed ultrasound proven NAFLD with transaminitis while on MTX therapy were identified. The demographic and clinical characteristics of the above patients (cases) were compiled and compared with age- and gender-matched controls who were RA patients on long standing MTX therapy without any episode of transaminitis.
    RESULTS: Among the 978 patients who had received MTX, the prevalence of MTX-associated NAFLD was 4.7% (46 patients). Compared to the controls, the cases had significantly higher mean cumulative dose of MTX (4.03 ± 2.25 g versus 10.04 ± 9.94 g, P ≤ 0.05), weekly dose of MTX (11.3 ± 4.8 mg versus 13.1 ± 4.4 mg weekly, P = 0.033), and fasting blood glucose (P = 0.029). Following multivariate regression analysis, only cumulative dose of MTX remained significant (P = 0.015). Among the cases, the cumulative dose of MTX was found to have a significant positive correlation with the alanine transaminase (ALT) level (P < 0.05, standardised beta coefficient 0.512).
    CONCLUSION: The cumulative dose of MTX was the only independent predictor of MTX-associated NAFLD with transaminitis.

  14. Fulltext The potential of intra-articular injection of chondrogenic-induced bone marrow stem cells to retard the progression of osteoarthritis in a sheep model
    Al Faqeh H, Nor Hamdan BM, Chen HC, Aminuddin BS, Ruszymah BH
    Exp Gerontol, 2012 Jun;47(6):458-64.
    PMID: 22759409 DOI: 10.1016/j.exger.2012.03.018
    In recent years, the use of bone marrow mesenchymal stem cell (BMSC) implantation has provided an alternative treatment for osteoarthritis. The objective of this study is to determine whether or not an intra-articular injection of a single dose of autologous chondrogenic induced BMSC could retard the progressive destruction of cartilage in a surgically induced osteoarthritis in sheep. Sheep BMSCs were isolated and divided into two groups. One group was cultured in chondrogenic media containing (Ham's F12:DMEM, 1:1) FD+1% FBS+5 ng/ml TGFβ3+50 ng/ml IGF-1 (CM), and the other group was cultured in the basal media, FD+10% FBS (BM). The procedure for surgically induced osteoarthritis was performed on the donor sheep 6 weeks prior to intra-articular injection into the knee joint of a single dose of BMSC from either group, suspended in 5 ml FD at density of 2 million cells/ml. The control groups were injected with basal media, without cells. Six weeks after injection, gross evidence of retardation of cartilage destruction was seen in the osteoarthritic knee joints treated with CM as well as BM. No significant ICRS (International Cartilage Repair Society) scoring was detected between the two groups with cells. However macroscopically, meniscus repair was observed in the knee joint treated with CM. Severe osteoarthritis and meniscal injury was observed in the control group. Interestingly, histologically the CM group demonstrated good cartilage histoarchitecture, thickness and quality, comparable to normal knee joint cartilage. As a conclusion, intra-articular injection of a single dose of BMSC either chondrogenically induced or not, could retard the progression of osteoarthritis (OA) in a sheep model, but the induced cells indicated better results especially in meniscus regeneration.

    Int J Rheum Dis, 2012 Oct;15(5):468-77.
    PMID: 23083037 DOI: 10.1111/j.1756-185X.2012.01753.x
    AIM: To determine the prevalence of sexual dysfunction (FSD) among women with rheumatoid arthritis attending the Rheumatology Clinic in Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and Hospital Putrajaya, Malaysia, and to determine its associations with potential clinical and disease activity factors.
    METHOD: This was a cross-sectional study involving women with rheumatoid arthritis between the ages of 20 and 60 years. A validated Malay Version Female Sexual Function Index (MVFSFI) was administered to diagnose FSD. Sociodemographic and disease activity profiles were obtained and those who had and did not have FSD were compared.
    RESULTS: Among 63 respondents, 51 patients were included in the analysis for FSD. The prevalence of FSD in women with rheumatoid arthritis attending UKMMC and Hospital Putrajaya Rheumatology Clinic was 29.4%. Erythrocyte sedimentation rate (ESR) and Disease Activity Score in 28 joints (DAS28-ESR) correlates with MVFSFI score with r=-0.364 (P=0.009) and r=-0.268 (P=0.057), respectively. Sociodemographic factors that correlate with MVFSFI score were: patient's age (r=0.520, P<0.001); duration of marriage (r=-0.355, P=0.001); husband's age (r=-0.460, P=0.001); age of oldest child (r=-0.449, P=0.001); and age of youngest child (r=-0.627, P<0.001).
    CONCLUSION: We found in this study that the prevalence of FSD in rheumatoid arthritis in our centers was 29.4%. Age and family dynamics appear to be more important predictors compared to disease activity.

  16. Fulltext Diagnostic value of anti-modified citrullinated vimentin in rheumatoid arthritis
    Maraina CH, Nurdayana AK, Rusni D, Azwany Y
    Int J Rheum Dis, 2010 Oct;13(4):335-9.
    PMID: 21199468 DOI: 10.1111/j.1756-185X.2010.01552.x
    BACKGROUND: Rheumatoid factors (RF) are currently used in the diagnosis of rheumatoid arthritis (RA). Several other autoantibodies found in RA are directed to epitopes in citrullinated proteins such as anti-cyclic citrullinated and recently anti-modified citrullinated vimentin (MCV).
    OBJECTIVE: In this study we determined the sensitivity and specificity of anti-MCV in comparison with anti-cyclic citrullinated peptide (CCP) antibodies and RF in RA patients and in a control group using the American College of Rheumatology (ACR) criteria as the gold standard.
    MATERIALS AND METHODS: A cross sectional study was conducted from January to December 2008 on 100 patients with RA and 153 patients with arthritis or arthralgia but not fulfilling ACR criteria for RA. Serum from each subject was tested for anti-MCV, anti-CCP antibodies and immunoglobulin G (IgG) RF by enzyme-linked immunosorbent assay. Sensitivity and specificity of the tests were evaluated using the ACR criteria as the gold standard.
    RESULTS: The sensitivity of RF was 85% with 74.5% specificity. For anti-CCP antibodies the sensitivity was 71% and the specificity was 94.8%. The sensitivity of anti-MCV antibodies was 80% with 59.5% specificity. The area under the curve for RF was 0.759, for anti-CCP antibodies was 0.866 and for anti-MCV antibodies was 0.681, while for at least one positive test it was 0.691.
    CONCLUSION: Anti-CCP antibodies have higher diagnostic specificity and positive predictive value than RF and anti-MCV antibodies. RF has the highest sensitivity when compared to anti-CCP and anti-MCV antibodies. Thus anti-MCV antibody is not a better marker when compared to RF or anti-MCV antibody in the diagnosis of RA patients.

    PMID: 21303477 DOI: 10.1111/j.1756-185X.2010.01573.x
    AIM: The purpose of this study is to compare the prevalence of rheumatoid factor (RF) isotypes and second generation anti-cyclic citrullinated peptides (anti-CCP) in Malaysian rheumatoid arthritis (RA) patients.
    METHODS: In this cross-sectional study, 147 established RA patients from three ethnic groups were recruited from a major rheumatology clinic in Malaysia. Enzyme-linked immunosorbent assays (ELISA) for serum RF isotypes IgA, IgG and IgM as well as second-generation anti-CCP were performed and the prevalence of each auto-antibody was compared in the three ethnic groups.
    RESULTS: The anti-CCP was the most prevalent auto-antibody in each of the ethnic groups, followed closely by RF IgM and RF IgG. Rheumatoid factor IgA was the least prevalent across all three ethnic groups. The anti-CCP-RF IgM combination provided the best test sensitivity. Seroprevalence of anti-CCP was strongly associated with the presence of each of the RF isotypes. The seroprevalence of RF and anti-CCP did not increase or decrease with advancing age, age at onset and disease duration.
    CONCLUSION: When used alone, anti-CCP provides a diagnostic advantage over RF IgM on the basis of test sensitivity. Considering the high cost of the anti-CCP assay, step-wise serum testing with IgM RF followed by anti-CCP may provide a more economically sensible option to optimize test sensitivity for RA.

    The effect of water extracts of Euphorbia hirta on the histological features and expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in the rat articular cartilage was investigated. Arthritis was induced in rats using Freund's Complete Adjuvant containing heat-killed M. tuberculosis, and treated with water extracts of E. hirta. Paraffin tissue sections of the arthritic joints were evaluated. The extent of cartilage degeneration was found to be greatest in rats treated with the highest dosage of E. hirta, followed by rats in the untreated group. Rats treated with the intermediary and low dosages of Euphorbia hirta showed improved histology. MMP-13 levels were found to be decreased with decreasing dosages of E. hirta. TIMP-1 levels were found to increase with decreasing dosages of E. hirta. MMP-3 levels fluctuated without any appreciable pattern. Low dosages of E. hirta seem to be beneficial in reducing cartilage degeneration in cases of arthritis.

    Rituximab is a B-cell-depleting monoclonal anti-CD20 antibody. It is widely used in haematology and rheumatology. However, usage of rituximab in immunosupressed patient has been associated with various opportunistic infections. The authors reported a case of refractory rheumatoid arthritis treated with rituximab, which later presented with non-resolving pneumonia with pulmonary nodule.
