    BACKGROUND: Musculoskeletal pain is common among teachers. Work-related psychosocial factors are found to be associated with the development of musculoskeletal pain, however psychological distress may also play an important role.

    OBJECTIVES: To assess the prevalence of self-reported low back pain (LBP), and neck and/or shoulder pain (NSP) among secondary school teachers; and to evaluate the association of LBP and NSP with psychological distress and work-related psychosocial factors.

    METHODS: This was a cross-sectional study conducted among teachers in the state of Penang, Malaysia. The participants were recruited via a two stage sampling method. Information on demographic, psychological distress, work-related psychosocial factors, and musculoskeletal pain (LBP and NSP) in the past 12 months was collected using a self-administered questionnaire. Poisson regression was used to estimate the prevalence ratio (PR) for the associations between psychological distress and work-related psychosocial factors with LBP and NSP.

    RESULTS: The prevalence of self-reported LBP and NSP among 1482 teachers in the past 12 months was 48.0% (95% Confidence Interval (CI) 45.2%, 50.9%) and 60.1% (95% CI 57.4%, 62.9%) respectively. From the multivariate analysis, self-reported LBP was associated with teachers who reported severe to extremely severe depression (PR: 1.71, 95% CI 1.25, 2.32), severe to extremely severe anxiety (1.46, 95% CI 1.22, 1.75), high psychological job demand (1.29, 95% CI 1.06, 1.57), low skill discretion (1.28, 95% CI 1.13, 1.47) and poorer mental health (0.98, 95% CI 0.97, 0.99). Self-reported NSP was associated with mild to moderate anxiety (1.18, 95% CI 1.06, 1.33), severe to extremely severe anxiety (1.25, 95% CI 1.09, 1.43), low supervisory support (1.13, 95% CI 1.03, 1.25) and poorer mental health (0.98, 95% CI 0.97, 0.99).

    CONCLUSIONS: Self-reported LBP and NSP were common among secondary school teachers. Interventions targeting psychological distress and work-related psychosocial characteristics may reduce musculoskeletal pain among school teachers.

    Radiosynovectomy is a novel method of treatment for several acute and chronic inflammatory joint disorders. A small amount of a beta-emitting radionuclide is injected into the affected joint delivering a radiation dose of 70 to 100 Gy to the synovia. The proliferative tissue is destroyed, secretion of fluid and accumulation of inflammation causing cellular compounds stops and the joint surfaces become fibrosed, providing long term symptom relief. The radionuclides are injected in colloidal form so that they remain in the synovium and are not transported by lymphatic vessels causing radiation exposure to other organs. Complete reduction of knee joint swelling has been seen in above 40% and pain relief in 88% of patients. Wrist, elbow, shoulder, ankle and hip joints showed significant improvement in 50-60% and restoration of normal function and long term pain relief has been achieved in about 70% of small finger joints. In hemophilic arthropathies complete cessation of bleeding in about 60% and improved mobility in 75% of patients has been reported.

    Multiple myeloma (MM) is characterized by progressive proliferation of malignant plasma cells, usually initiating in the bone marrow. MM can affect any organ; a total of 7 - 18% of patients with MM demonstrate extramedullary involvement at diagnosis. Non-secretory multiple myeloma (NSMM) is a rare variant that accounts for 1 - 5% of all cases of multiple myeloma. The disease is characterized by the absence of monoclonal gammopathy in serum and urine electrophoresis. Our case report highlights the diagnostic challenge of a case of NSMM with extensive extramedullary involvement in a young female patient who initially presented with right shoulder pain and bilateral breasts lumps. Skeletal survey showed multiple lytic bony lesions. The initial diagnosis was primary breast carcinoma with osseous metastases. No monoclonal gammopathy was found in the serum or urine electrophoresis. Bone marrow and breast biopsies revealed marked plasmacytosis. The diagnosis was delayed for a month in view of the lack of clinical suspicion of multiple myeloma in a young patient and scant biochemical expression of non-secretory type of multiple myeloma.

    CONTEXT: Breast cancer is the most prevalent cancer amongst women but it has the highest survival rates amongst all cancer. Rehabilitation therapy of post-treatment effects from cancer and its treatment is needed to improve functioning and quality of life. This review investigated the range of methods for improving physical, psychosocial, occupational, and social wellbeing in women with breast cancer after receiving breast cancer surgery.
    METHOD: A search for articles published in English between the years 2009 and 2014 was carried out using The Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects, PubMed, and ScienceDirect. Search terms included: 'breast cancer', 'breast carcinoma', 'surgery', 'mastectomy', 'lumpectomy', 'breast conservation', 'axillary lymph node dissection', 'rehabilitation', 'therapy', 'physiotherapy', 'occupational therapy', 'psychological', 'psychosocial', 'psychotherapy', 'exercise', 'physical activity', 'cognitive', 'occupational', 'alternative', 'complementary', and 'systematic review'.
    STUDY SELECTION: Systematic reviews on the effectiveness of rehabilitation methods in improving post-operative physical, and psychological outcomes for breast cancer were selected. Sixteen articles met all the eligibility criteria and were included in the review.
    DATA EXTRACTION: Included review year, study aim, total number of participants included, and results.
    DATA SYNTHESIS: Evidence for exercise rehabilitation is predominantly in the improvement of shoulder mobility and limb strength. Inconclusive results exist for a range of rehabilitation methods (physical, psycho-education, nutritional, alternative-complementary methods) for addressing the domains of psychosocial, cognitive, and occupational outcomes.
    CONCLUSION: There is good evidence for narrowly-focused exercise rehabilitation in improving physical outcome particularly for shoulder mobility and lymphedema. There were inconclusive results for methods to improve psychosocial, cognitive, and occupational outcomes. There were no reviews on broader performance areas and lifestyle factors to enable effective living after treatment. The review suggests that comprehensiveness and effectiveness of post-operative breast cancer rehabilitation should consider patients' self-management approaches towards lifestyle redesign, and incorporate health promotion aspects, in light of the fact that breast cancer is now taking the form of a chronic illness with longer survivorship years.

    The aim of the study was to assess the outcomes of grandmultiparous women receiving the current obstetric care in Maternity Hospital Kuala Lumpur. Recent data regarding some of the complications are conflicting and the significance of grandmultiparity is now in question. Therefore, a retrospective cohort study of 237 grandmultiparous and 254 multiparous women were undertaken. Chi-squared and t test were used (P<0.05) where appropriate. The results revealed that grandmultiparous women tend to be Malays, age above 35, have late antenatal booking and suffered from anemia and non-proteinuric hypertension. There was no significant difference in diabetes and glucose intolerance, ante partum and post partum hemorrhage. There was a significantly lower risk of first and second-degree perineal tear, and prolonged first stage of labor. There was a significant increased in induction of labor but there was no uterine rupture and no increased in Cesarean Section. There was an increased in meconium stain liquor but there was no increased risk of fetal distress. The fetal outcome was good and there was no tendency to macrosomic infants or shoulder dystocia. With adequate care, the maternal fetal outcome of grandmutiparous women is good and comparable to the multiparous women. Anemia is still common and patient education is important to overcome this problem.

    Studies have identified working postures as a major risk factors associated with Work-related musculoskeletal disorders (WMSD) in industries. This study investigated the prevalence of WMSD among assembly workers in Malaysia and how psychosocial factors such as personal values and workers relationship with family and superior are associated with discomfort and pain. A survey was conducted among 127 workers at assembly process in the manufacturing industry. The workers were aged 28.74±6.74 years and 64.6% of them were males. Analysis of Variance (ANOVA) was used to determine the effect of workplace factors on WMSD at different body regions. Spearman’s rank correlation was used to investigate association between psychosocial factors and occurrence of discomfort and pain. Only occupation and job activities revealed any significant different with WMSD in the major body regions while there was no significant difference in gender, age and work duration classifications. Shoulder painis the most prevalent in terms of frequency and intensity of occurrence. Psychosocial issues that have to do with person values, effect of job on family relationship and workers rapport with superiors are all found to be associated with the discomfort and pain among the occupational group. Employers and concerned government agencies need to take more proactive steps in tackling the problem as the occurrence of WMSD will have a significant effect on the overall wellbeing of the working population.

    Aims: The purpose of this study was to evaluate web-based Knowledge, Attitude and Practice (KAP) intervention on office ergonomics - a unique method for prevention of musculoskeletal discomfort (MSD) - in corporate offices that influences behavior modification.

    Background: With the increasing use of computers, laptops and hand-held communication devices globally among office employees, creating awareness on office ergonomics has become a top priority. Emphasis needs to be given on maintaining ideal work postures, ergonomic arrangement of workstations, optimizing chair functions, as well as performing desk stretches to reduce MSD arising from the use of these equipment, thereby promoting safe work practices at offices and home, as in the current scenario many employees work from home with flexible work hours. Hence, this justifies the importance of our study.

    Objective: To promote safe working by exploring cost-effective communication methods to achieve behavior change at distant sites when an on-site visit may not be feasible.

    Materials and Methods: An invitation was sent by the Medical and Occupational Health Team of a multinational corporation to all employees at their offices in Sri Lanka, Singapore, and Malaysia to take up an online Nordic questionnaire, a screening tool for musculoskeletal symptoms, shared in local languages on two occasions - baseline evaluation (n = 240) and a follow-up evaluation after 3 months (n = 203). After completing the baseline questionnaire, employees were immediately trained on correct postures and office ergonomics with animation graphics. The same questionnaire was sent again after a 12-week gap only to those employees who responded to the baseline questionnaire on initial assessment.

    Statistical Analysis Used: Data collected were analyzed using the Statistical Package for the Social Sciences (SPSS) version 20.0 software and variables were compared using odds ratio as well as Chi-square test.

    Results: Of the 203 employees who responded, 47.35% had some musculoskeletal symptoms. Among them 58.7% had lower back pain, 46.9% had upper back pain, 44.1% had wrist pain, 39.5% had shoulder pain, and 37% had knee pain. The percentages are high as some participants had multiple complaints i.e. 2 or 3 complaints. However, only 40% of these employees had ongoing symptoms at the time of evaluation (past 7 days). A subsequent 3-month evaluation after web-based intervention showed a significant 41-50% decline in ongoing symptoms.

    Conclusions: We conclude that newer technology using web-based animation graphics is a highly efficient technique to create office ergonomics awareness and has the potential to become a best practice in countries where language is a communication barrier and an on-site visit may not be feasible due to meagre resources.

    Aims: The aim of this study is to compare obstetric outcomes between overweight and class 1 obesity among pregnant women in their first pregnancy based on WHO's BMI cut-offs and the potential public health action points identified by WHO expert consultations specific for high-risk population such as Asians.

    Methods: This is a retrospective cohort review of data obtained from the Malaysian National Obstetrics and Gynaecology Registry between the year 2010 and year 2012. All women in their first pregnancy with a booking BMI in their first trimester were included in this study. The association between BMI classifications as defined by the WHO cut-offs and the potential public health action points identified by WHO expert consultations towards adverse obstetric outcomes was compared.

    Results: A total of 88,837 pregnant women were included in this study. We noted that the risk of adverse obstetric outcomes was significantly higher using the public health action points identified by WHO expert consultations even among the overweight group as the risk of stillbirths was (OR 1.2; 95% CI 1.0,1.4), shoulder dystocia (OR 1.9; 95% CI 1.2,2.9), foetal macrosomia (OR 1.8; 95% CI 1.6,2.0), caesarean section (OR 1.9; 95% CI 1.8,2.0) and assisted conception (OR 1.9; 95% CI 1.6,2.1).

    Conclusion: A specifically lower BMI references based on the potential public health action points for BMI classifications were a more sensitive predictor of adverse obstetric outcomes, and we recommend the use of these references in pregnancy especially among Asian population.

    Introduction: The purpose of this study is to identify the incidence of clavicle fractures in newborn
    associated with fetal, maternal and process of deliveries in Kuantan General Hospital from June 2012 until
    January 2014. This study is to determine epidemiological data of clavicle fractures, maternal and baby risk
    factors associated with clavicle fractures of newborn and its’ outcome.

    Methods: This is a prospective
    study. 13 patients were identified to fulfill the inclusion criteria of the study. The data of
    sociodemographic, associated fetal and maternal risk factors and the outcomes were recorded using
    proforma. The statistical data analysis was done using SPSS 12.0.

    Results: Out of 20,257 live births at our
    centre during the study period, 13 infants were diagnosed to have clavicle fractures, giving an incidence of
    0.64 per 1000 live births. There were 5 (38.5%) left, 7 (53.8%) right and one (7.7%) bilateral fracture. All
    fractures located at the mid shaft of the clavicle and none have associated brachial plexus injuries. All
    infants were delivered through vaginal delivery (61.5%); five through assisted delivery (instrumental); 2
    (15.4%) forcep and 3 (23.1%) vacuum. Two of the babies developed shoulder dystocia. The average birth
    weight was 3371 grams (SD 0.269) and mean gestational age was 38.7 weeks (SD 1.16). Five of the mothers
    (38.5%) were primigravida and eight (61.5%) were multigravida in which,7 (53.8%)were healthy without
    other co-morbidty, 5 (38.5%) having gestational diabetis and one (7.7%) hypertension. The average maternal
    weight was 62.0 kg and height 1.58 metres with average BMI of 24.16 (3.29SD). All eventually had a
    complete recovery at 6 weeks with clinical and radiological evident of fracture union.

    Conclusions: In
    conclusion, all patients with clavicle fractures were found following vaginal delivery. There were no
    associations between neonatal clavicle fractures with maternal or baby risk factors. All fractures healed
    without any complications.

    BACKGROUND: Despite evidence of physical (illness) and mental (stress) health problems, there appears to be a lack of studies or concern regarding occupational safety and health among educators in Malaysia.

    OBJECTIVE: To review the prevalence of illness, stress, and corresponding risk factors among educators in Malaysia.

    METHOD: Scopus, ProQuest, PubMed, ScienceDirect, CAB, and other computerized databases were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies published between January 2013 and April 2019 on the prevalence and associated risk factors of illness and stress among educators (S1 Checklist). The keywords used included educator, teacher, lecturer, academic staff, teaching profession, university staff, academician, faculty, illness, injury, disease, pain, WMSD, dysphonia, hoarseness, stress, mental health, strain, health problem, disorder, and/or Malaysia. Selected studies were evaluated by quality assessment.

    RESULTS: Twenty-two articles fulfilled the eligibility criteria. The prevalence of illness and stress was determined for low back pain (33.3-72.9%); upper back pain (33.33-56.4%); neck/shoulder pain (40.4-80.1%); upper arm discomfort (91.3%); forearm pain (89.6%); wrist pain (16.7-93.2%); hip pain (13.2-40.9%); thigh discomfort (91.8%); lower leg discomfort (90.5%); knee pain (23.7-88.0%); ankle/feet pain (19.3-87.7%); elbow pain (3.5-13.0%); voice disorder (10.4-13.0%) and stress (5.5-25.9%). Sex, education level, teaching experience, quality of life, anxiety, depression, coping styles, and others were reported as associated risk factors across the studies.

    CONCLUSIONS: There appears to be a cause for concern regarding musculoskeletal disorders, voice disorder, and stress reported among educators in Malaysia. While most risk factors matched those reported in studies elsewhere, others such as school characteristics (school level, government or private school, and location [rural/urban]) have not been investigated.

    This position development conference (PDC) Task Force examined the assessment of bone status in orthopedic surgery patients. Key questions included which orthopedic surgery patients should be evaluated for poor bone health prior to surgery and which subsets of patients are at high risk for poor bone health and adverse outcomes. Second, the reliability and validity of using bone densitometry techniques and measurement of specific geometries around the hip and knee before and after arthroplasty was determined. Finally, the use of computed tomography (CT) attenuation coefficients (Hounsfield units) to estimate bone quality at anatomic locations where orthopedic surgery is performed including femur, tibia, shoulder, wrist, and ankle were reviewed. The literature review identified 665 articles of which 198 met inclusion exclusion criteria and were selected based on reporting of methodology, reliability, or validity results. We recommend that the orthopedic surgeon be aware of established ISCD guidelines for determining who should have additional screening for osteoporosis. Patients with inflammatory arthritis, chronic corticosteroid use, chronic renal disease, and those with history of fracture after age 50 are at high risk of osteoporosis and adverse events from surgery and should have dual energy X-ray absorptiometry (DXA) screening before surgery. In addition to standard DXA, bone mineral density (BMD) measurement along the femur and proximal tibia is reliable and valid around implants and can provide valuable information regarding bone remodeling and identification of loosening. Attention to positioning, selection of regions of interest, and use of special techniques and software is required. Plain radiographs and CT provide simple, reliable methods to classify the shape of the proximal femur and to predict osteoporosis; these include the Dorr Classification, Cortical Index, and critical thickness. Correlation of these indices to central BMD is moderate to good. Many patients undergoing orthopedic surgery have had preoperative CT which can be utilized to assess regional quality of bone. The simplest method available on most picture archiving and communications systems is to simply measure a regions of interest and determine the mean Hounsfield units. This method has excellent reliability throughout the skeleton and has moderate correlation to DXA based on BMD. The prediction of outcome and correlation to mechanical strength of fixation of a screw or implant is unknown.

    OBJECTIVE: The main aim of the study was to analyze the outcomes of clavicle fractures in adults treated non-surgically and to evaluate the clinical effects of displacement, fracture patterns, fracture location, fracture comminution, shortening and fracture union on shoulder function.

    METHODS: Seventy clavicle fractures were non-surgically treated in the Orthopedics Department at the Tuanku Ja'afar General Hospital, a tertiary care hospital in Seremban, Malaysia, an average of six months after injury. The clavicle fractures were treated conservatively with an arm sling and a figure-eight splint for three weeks. No attempt was made to reduce displaced fractures, and the patients were allowed immediate free-shoulder mobilization, as tolerated. They were prospectively evaluated clinically and radiographically. Shoulder function was evaluated using the Constant scoring technique.

    RESULTS: There were statistically significant functional outcome impairments in non-surgically treated clavicle fractures that correlated with the fracture type (comminution), the fracture displacement (21 mm or more), shortening (15 mm or more) and the fracture union (malunion).

    CONCLUSION: This article reveals the need for surgical intervention to treat clavicle fractures and improve shoulder functional outcomes.

    The computer is well known as one of the important tools in the office that gives a lot of benefits but silently leads to musculoskeletal pain. There are many different kinds of musculoskeletal complaints pain but the most common seen among computer users in developed countries is the complaint of arm, neck and shoulder (CANS). Despite this, definite factors that can be associated with the prevalence of CANS have not been established. This study was conducted to identify the prevalence and factors associated with work-related complaints of arm, neck and shoulder (CANS) among office workers in Selangor and Kuala Lumpur. A survey study design was conducted where 110 (n=110) office workers were recruited from around the Selangor and Kuala Lumpur area for 5 months periods. Participants were required to answer the Maastricht Upper Extremity Questionnaire (MUEQ) and the Level of Ergonomic Knowledge Questionnaire. The study showed the highest percentage of CANS reported was at neck region (53.6% of participants), followed by shoulders with 53.0%. The majority of participants have low level of computer ergonomic awareness where only 19.09% (n=21) from government sector and 10% (n=11) office workers from private sector reported knowledge of ergonomics. Majority of the participants did not have the know-how in implementing correct computer ergonomics. However there was a weak association (r=

    Introduction: This is a cross-sectional study of 37 patients with AO type C (complete intra-articular) fractures of the distal radius, evaluating the functional, anatomical, and patient rated outcomes one year after primary fixation with a volar locking plate.

    Methods: Functional outcomes were assessed based on the grip strength, and the range of motion of forearm and wrist. Anatomical outcomes were assessed based on the radial inclination, radial height, volar tilt, and articular step or gap. Patient rated outcome was measured with a Disability of arm, shoulder and hand (DASH) questionnaire.

    Results: One year after surgery, 24 (64%) patients achieved good and excellent anatomical results, and DASH scores were acceptable in 73% of patients. Most of the patients had achieved 80% of their grip strength. The mean DASH score of 12.3 was comparable with other studies. Grip strength, radial inclination and volar tilt had a significant correlation with the DASH score.

    Conclusion: Volar locking plates can be used to achieve optimal reduction in all three parameters in the treatment of AO type C fractures of the distal radius. Versatile fracture fragment reduction and angular stability enable rehabilitation hence obtaining good functional outcomes.

    Chondrosarcoma is the third most common primary tumour of the bone, after myeloma and osteosarcoma. Most of the chondrosarcoma grow slowly and rarely metastasize, and they have an excellent prognosis after adequate surgery. However most of them are chemo or radio-resistant. We report a case of primary chondrosarcoma of proximal humerus in a 36-year-old female who presented with a six years history of left shoulder swelling and restricted range of motion. Trucut biopsy showed a well-differentiated chondrosarcoma. The patient underwent forequarter amputation of left upper limb and was started on chemotherapy following operation.

    Differential scanning calorimetry (DSC) is developed and used for detection of butter adulteration with lard. Butter has the similar characteristics to lard makes lard a desirable adulterant in butter. DSC provides unique thermal profiling for lard and butter. In the heating thermogram of the mixture, there was one major endothermic peak (peak A) with a smaller shoulder peak embedded in the major peak that gradually smoothed out to the major peak as the lard percent increased. In the cooling thermogram, there were one minor peak (peak B) and two major exothermic peaks, peak C which increased as lard percent increased and peak D which decreased in size as the lard percent increased. From Stepwise Multiple Linear Regression (SMLR) analysis, two independent variables were found to be able to predict lard percent adulteration in butter with R2 (adjusted) of 95.82. The SMLR equation of lard percent adulteration in butter is 293.1 - 11.36 (Te A) - 2.17 (Tr D); where Te A is the endset of peak A and Tr D is the range of thermal transition for peak D. These parameters can serve as a good measurement parameter in detecting lard adulteration in butter. DSC is a very useful means for halal screening technique to enhance the authenticity of Halal process.

    Elderly are exposed to physical impairment. This has a strong impact on their daily activities including
    frying, which is one of the most popular cuisine preparations. The stove height and work envelope
    are two major ergonomic issues in performing cooking task. There has been little research focusing
    on Malaysian elderly task performing in addressing these issues. The objectives of this study were to
    identify the acceptable stove height and depth and to determine the working envelope among Malaysian
    elderly using anthropometric data. A total of 55 Malaysian elderly (25 male and 30 female) aged between
    60 to 85 years participated in this study. Five body measurements were taken from each subject using
    an anthropometer. The measurements are stature height, shoulder height, arm span, arm reach forward
    and waist height. Apart from these anthropometric measurements, their present stove height was also
    measured. The acquisition of stove height dimensions was performed through a series of door to door
    visit of the elderly homes in Kg. Sg. Merab. These variables were used to estimate the elderly working
    envelope and determine the stove height, width and depth. Data were analysed using SPSS software. The
    waist height dimension was to estimate the stove height, the arm reach forward for the depth and the arm
    span for the length of the table-top where the stove was placed. Meanwhile the stature and shoulder height
    were used for estimating the position of the overhead compartment or placement of cooking utensils.

    percentile was also applied for the setting
    of the working envelope so as to provide better
    reaching tolerances. Meanwhile, standard was used
    to compare the present state of the studied kitchen
    setting. The results show that 56.4% of the elderly
    waist height is lower than the standard table-top
    height which is 36 inches (91.4cm) and 36.4% of the stove height was found higher than that of the standard. This could apparently cause fatigue and
    discomfort to shoulders, the neck, the arm and the back of the user. Anthropometrics measurements can
    be used for estimating the stove height, length and depth. These could also calculate a space taken for
    certain physical activities, such as frying task envelope. Providing a good combination of stove height,
    length, depth and ergonomic working envelope could hopefully improve the elderly cooking task and
    increase their quality of life.
