    The aim of this descriotive study is to determine the incidence of injuries among recreational badminton players. We evaluated 86 recreational badminton players in the city of Malacca; 35 were excluded for fitting the exclusion criteria. The average recreational badminton player was 36.13 years old and had been playing badminton for the past 17.84 years at a frequency of 2.11 times per week. 39.21% of the recreational badminton players complained of recent injuries in relation to playing badminton. Our data showed that the most common injury sustained by recreational badminton players was pain and stiffness at the shoulder joint. None of the injuries sustained by the players in our data were serious enough to warrant any form of surgical intervention. We conclude that badminton is a sport of relatively low risk and that the majority of related injuries were chronic overuse injuries.

    ‘Nasi kandar’ is defined as boiled white rice placed inside a wooden basket and carried on the shoulder using a pole. The rice is served with a variety of pairing dishes that are usually fried, curried or boiled. The tradition of carrying rice and pairing dishes on the shoulder began to die out in the 20th century as seller resorted to a more conventional way of selling ‘nasi kandar’. The ‘nasi kandar’ business in Malaysia has evolved from being sold as a street food into a multi-million dollar franchise business rivalling the fast food business. It is available 24 hours and enjoyed by Malaysians from all walks of life. This study aims to compare ‘nasi kandar’ eating pattern among patrons in the Klang Valley and Penang. Three hundred sets of questionnaires were answered and collected. Data from the questionnaires were analyzed in PASW 18.0 using descriptive statistics and chi-square test for association. Klang Valley patrons (72%) would consume ‘nasi kandar’ once a week. More than half (53.3%) of the patrons from Penang consumed ‘nasi kandar’ more than twice a week. A significant relationship exists between patron’s region and frequency of ‘nasi kandar’ consumption where p = <0.0001 and r = 0.277. A significant but moderate relationship between patron’s region and consumption of ‘nasi kandar’ during breakfast (p = <0.001, r = 0.250), lunch (p = <0.0001, r = 264) and dinner (p = <0.0001, r = 0.336). Patrons in Penang consumed ‘nasi kandar’ more often than their Klang Valley counterparts. Klang Valley patrons were more particular than Penang patrons when it comes to cleanliness, menu pricing, friendly service, air-condition and separate smoking area. Klang Valley patrons tend to consume more chicken based dishes while Penang patrons tend to consume more meat, fish, and squid based dishes.

    Working in a safe working posture is a necessity to enhance occupational health of industrial workers. Poor
    working posture may lead to injuries, discomfort and fatigue to the workers. The objective of this study is to survey the
    postures practised by the Malaysian industrial workers. A questionnaire survey was performed among 282 Malaysian
    industrial workers in 10 different industries. From the answered questionnaire, it was observed that shoulder at chest
    level (30.1%), back in a bent forward (33.3%) and lifting heavy load (44.7%) are the major work postures practised by
    most of industrial workers. This survey identifies that working with shoulder and hand at chest level and back region
    moderately bent forward is the main working posture practice by worker. Workers also reported lifting load below 5 kg
    at the workstation. This survey recommended for industrial workers to be aware of the comfortable working posture
    to avoid injury.

    Background: The study investigated the effects of isokinetic versus isotonic training among adolescent state-level weightlifters in terms of total leukocytes, total lymphocytes, and its subsets following 24 sessions of training program and a month following training program cessation.

    Methods: Nineteen adolescent state-level weightlifters were assigned into isokinetic or isotonic groups. All participants were recruited from a pool of weightlifters with standardized training program provided by their coach. Series of immunological tests were carried out before the commencement, immediately upon the completion, and a month after the cessation of the additional training program to evaluate total leukocytes and lymphocytes count.

    Results: The results revealed a significant time and group interaction and main effects of time on mean total leukocytes (P < 0.05). Mean total leukocytes count at posttest decreased in both groups. In isotonic group, it was further decreased following 1 month of training cessation (P < 0.05) but not in the isokinetic group. However, the decrement was not high and the values were in the normal range. No significant time and group interaction was observed in total lymphocytes and its subsets count.

    Conclusions: Eight weeks of isokinetic and isotonic additional training with emphasis on shoulder joint only affect mean total leukocytes count in state-level adolescent weightlifters.

    ABSTRACT: Proximal humerus fracture is the second most common fracture of the upper extremity and presents several unique problems such as anatomical complexity, high risk of avascular necrosis, minimal bone stock for purchase, significant morbidity, and lack of a universally accepted treatment. Recent treatments for proximal humerus fractures include use of minimally invasive plate osteosynthysis (MIPO). The aim of this cross-sectional study was to evaluate the outcomes of our less invasive technique using a modified anterolateral approach for treatment of proximal humerus fractures. Ten such operative procedures were performed in patients of varying age and with varied mechanism of injury from 2002-2011. All cases were conducted in an acute setting. There were no cases of infection and the functional outcome scores were good. This approach represents an alternative treatment for closed proximal humerus fracture but more extensive studies are needed.

    KEY WORDS: Proximal humerus fracture, MIPO, less invasive,anterolateral approach.

    Validity test is important during the development of ergonomics measurement. Failure to conduct validity tests will result in the measurement method being developed to be incapable of providing reliable ergonomics measurements. The objective of this study is to conduct validity test on the simple method ergonomics measurement which was developed. The method named Simple Ergonomics Risks Assessment (SERA). Content validity test and criterion validity test were conducted. The content validity test consists of 6 ergonomics experts who actively provide inputs and positive feedbacks to improve the measurement method being developed. Meanwhile, the criterion validity test involves data collection of complaints on body parts among oil palm workers which were derived from Nordic Musculoskeletal Questionnaire (NMQ) and ergonomics risk assessment scores obtained from SERA. Both findings were tested with the Chi-square test to explore possible relations between the two findings. Results from the test conducted showed that there are significant relations in the scores of neck posture; hip, right and left shoulder, right and left wrists and the right hand associated with fresh fruit bunch (FFB) harvesting activities. In the loose fruits collection, the Chi-square test showed significant relations in the scores of neck posture, hip, right and left shoulders, right wrist, right arm and the left hand. However, there are body parts such as the legs which showed no significant relation. More tests should be conducted to further explore the validity of the method being developed. Findings from both validity tests show that SERA were verified by the experts and tested with validated method so that it is valid to be applied in the future.

    The case notes of 102 patients (117 shoulder dislocations) were reviewed retrospectively to improve the understanding of the epidemiology of this common injury. Eighty-one dislocations were primary and 36 dislocations were second or recurrent dislocations. The age distribution was characterized by a peak in male patients aged between 21-30 years. The mean age for males was 30.5 years and 47.7 years for females. The male:female ratio in first time dislocations was 5:2, while it was 5:1 in recurrent dislocations. Ninety-eight percent were anterior dislocations and 2% were posterior dislocations. Greater tuberosity fractures were found in 17 patients and almost half of these patients were aged between 41-50 years. The most common cause of first time dislocation was a direct blow or fall onto the shoulder, accounting for 42 patients (55%). The majority of these patients were aged 40 years and above. Next common cause was motor vehicle accident which occurred mostly in the younger age group. Dislocations due to sporting injuries accounted for only 5.3% of all first time dislocations. Nearly 97% were successfully reduced without a general anaesthesia. Seventy-seven percent of the patients had their shoulders immobilized after reduction, mostly with body strapping only. Fifteen patients (14.7%) were referred for physiotherapy for stiffness. Few operations were performed for recurrent dislocations but surgery does not appear to be well accepted as yet by our patients.

    A well-supported and well-resolved phylogeny based on a concatenated data set from one mitochondrial and two nuclear genes, six morphological characters, and nine color pattern characters for 44 of the 50 species of the Southeast Asian Rock Geckos (genus Cnemaspis Strauch, 1887) is consistent with the previous taxonomy of Cnemaspis based solely on morphology and color pattern. Cnemaspis is partitioned into four major clades that collectively contain six species groups. The monophyly of all clades and species groups is strongly supported and they are parapatrically distributed across well-established, biogeographical regions ranging from southern Vietnam westward through southern Indochina, southward through the Thai-Malay Peninsula, then eastward to Borneo. Eight new species (Cnemaspis omari sp. nov. from the Thai-Malaysian border; C. temiah sp. nov. from Cameron Highlands, Pahang, Malaysia; C. stongensis sp. nov. from Gunung Stong, Kelantan, Malaysia; C. hangus sp. nov. from Bukit Hangus, Pahang, Malaysia; C. sundagekko sp. nov. from Pulau Siantan, Indonesia; C. peninsularis sp. nov. from southern Peninsular Malaysia and Singapore, and C. mumpuniae sp. nov. and C. sundainsula sp. nov. from Pulau Natuna Besar, Indonesia) are described based on morphology and color pattern and all but C. sundagekko sp. nov. are included in the phylogenetic analyses. Cnemaspis kendallii is polyphyletic and a composite of six species. An updated taxonomy consistent with the phylogeny is proposed for all 50 species and is based on 25 morphological and 53 color pattern characters scored across 594 specimens. Cladogenetic events and biogeographical relationships within Cnemaspis were likely influenced by this group's low vagility and the cyclical patterns of geographical and environmental changes in Sundaland over the last 25 million years and especially within the last 2.5 million years. The phylogeny indicates that nocturnality, diurnality, substrate preferences, and the presence of ocelli in the shoulder regions have evolved independently multiple times.

    Traditionally, picture-based password systems employ password objects (pictures/icons/symbols) as input during an authentication session, thus making them vulnerable to "shoulder-surfing" attack because the visual interface by function is easily observed by others. Recent software-based approaches attempt to minimize this threat by requiring users to enter their passwords indirectly by performing certain mental tasks to derive the indirect password, thus concealing the user's actual password. However, weaknesses in the positioning of distracter and password objects introduce usability and security issues. In this paper, a new method, which conceals information about the password objects as much as possible, is proposed. Besides concealing the password objects and the number of password objects, the proposed method allows both password and distracter objects to be used as the challenge set's input. The correctly entered password appears to be random and can only be derived with the knowledge of the full set of password objects. Therefore, it would be difficult for a shoulder-surfing adversary to identify the user's actual password. Simulation results indicate that the correct input object and its location are random for each challenge set, thus preventing frequency of occurrence analysis attack. User study results show that the proposed method is able to prevent shoulder-surfing attack.

    HyperDSC™(fast scan rate) was used to study the melting behavior of canola (CLO), sunflower (SFO), palm olein (PO), rice bran oils (RBO), and cocoa butter (CB), and was compared to the melting behaviors using conventional DSC. There was an increase in sensitivity with increase in scan rate. Slow scan rate (5 to 20C/min) gave low sensitivity, which increased when the scan rates were increased to 50, 100 and 200C/min. Peak resolution was affected by scan rate depending on the sample weight. Increase in the size of sample coupled with the use of fast scan rate decreased the peak resolution. Generally small sample sizes gave better peak resolution. Results of the effect of scan rate on glass transition (Tg) shows that Tg, which is a weak transition especially in crystalline and low amorphous materials was not detected using conventional scan rates (5 to 20oC/min). It was however detected using of hyperDSC™ scan rates (100 to 200oC/min). Increasing the scan rate resulted in an increase in the peak temperature and the elimination of shoulder peaks, which were caused due to the polymorphic behavior of the triacylglycerols in the oils. The increase in peak temperature caused a shift in the peak position towards a higher temperature value. There is a positive correlation between the peak temperature and scan rate. The correlation coefficients (r) for CLO, SFO, PO, RBO and CB were 0.96, 0.95, 0.97, 0.96 and 0.96 respectively.

    It is very rare indeed in the practice of children's orthopaedics today in Malaysia that the natural history of long bone osteomyelitis is seen. A case is presented where a shoulder abscess in a 3-year-old child developed into septic arthritis of the shoulder and subsequently chronic osteomyelitis of the adjacent humerus. The parents refused active surgical debridement and sequestrectomies. Three years later the child had regenerated a new humerus over the sequestra. Radiographs are presented illustrating the entire natural history of osteomyelitis with the regeneration of a new humerus.

    Introductions: Call center has been defined as a working environment in which uses telephone and computer for the purpose of marketing and manage communication with prospect clients or existing clients (Rocha, Glina, Morinho and Nakasato, 2005; Sprigg, Smith and Jackson, 2003).
    Methodology: The study was conducted via observation of working condition and face to face interview with call center operators. Measurement of anthropometrics was also conducted.
    Results: Ergonomics issues found at call center were inappropriate work condition and workstation which lead to awkward sitting posture (sitting with forward leaning posture, raised shoulder, feet not supported on floor). Besides that organizational policy which required high job demand and subsequently lead to prolonged sitting and static posture (very minimal posture changes). Combination all these factors lead to musculoskeletal symptoms and the operators reported of having neck, shoulder, upper back and lower back pain compared to other body parts.
    Conclusion: The management should embark on organization wide ergonomics management program and should review the current policy and create safe and healthy working environment by providing suitable workstation for the operators in order to prevent musculoskeletal.

    A 28-year-old man presented with a chief complaint of rashes all over his body. He had a history of a trip to Langkawi Island, a famous island resort off the west coast of Malaysia, over the Chinese New Year’s weekend. According to him, he had a lot of fun with a group of friends at the sunny beach and the beautiful sea. There were no untoward incidents and they were perfectly well when they returned home after a 2-day trip. On the evening of the second day after his return, he noticed rashes appearing over his body, notably on shoulders and trunk. These rashes were little painful in nature.

    Reported is the first case of syringomyelia and syringobulbia associated with Arnold Chiari I malformation in a Malaysian child. The initial complaint was that of unilateral anhidrosis of the face. The chief presenting features were dissociated sensory loss, asymmetrical weakness of the left upper limb associated with subluxation of left shoulder and signs of upper motor neurone lesion in the left lower limb. One unusual feature was the presence of vesiculation followed by ulceration of the pinnae of both ears. Magnetic resonance imaging (MRI) of the posterior fossa and cervical and thoracic cord facilitated the diagnosis and was the most useful diagnostic procedure in this child.

    This study was conducted to investigate i) while the shoulder was in 180° of flexion and the elbow extended, which of the forearm position (supination, pronation and neutral) can generate the greatest handgrip strength, ii) is there any correlation of the handgrip strength between the dominant hand (right hand) and non-dominant hand (left hand) in each forearm position, and iii) will the dominant hand possessed 10% higher handgrip strength than the non-dominant hand. 100 right handed sedentary active students age 22.20 years old (± 1.03), height 172.83 cm (± 6.37), body mass 68.87 (± 11.52) and grip position 3.77 (± 0.77) were recruited in this study. The result indicated that for both the dominant and non-dominant hand, when the shoulder is in 180˚ flexion of the body with the elbow extended, the greatest grip strength was obtained when the forearm was in neutral position followed by pronation and supination position. Post Hoc analysis showed that for both dominant hand and non-dominant hand, pronation and supination forearm position produced greater strength score compared to supination forearm position (p0.05). In all forearm position, participants were shown to produced significantly greater strength in their dominant hand and all the scores were more than 10% greater compared to when using non-dominant hand. Positive relationships were also found for the strength score between dominant hand and non-dominant hand. As the conclusion, different shoulder, elbow and forearm position can affect handgrip strength.

    The management of post-radiation wound breakdown over the posterior cervico thoracic region can be a challenging task for a surgeon. The aim of the treatment is to produce a well vascularized and a low tensile flap which will close a large defect. We describe the use of the lower trapezius flap to reconstruct the wound breakdown and to obtain stable tissue coverage in a patient with post- radiation necrosis. This flap minimizes the disruption of the scapula-thoracic function while preserving the range of movement over the shoulder. From the literature review, it was noted that the dorsal scapular artery (DSA) and transverse cervical artery (TCA) aid in the blood supply to the trapezius muscle and prevent local necrosis during rotation of the flap. The trapezius flap is widely accepted because of the minor donor site morbidity, large arc of rotation and adequate blood supply.

    We report a case of a broken K-wire migrating to the cervical spine from the right clavicle in a 9-year-old child. The initial diagnosis, fracture of the clavicle with an acromioclavicular joint dislocation, was treated by open reduction and K-wiring. One K-wire broke and migrated to the neck, posterolateral to the C6 vertebra. The K-wire was removed percutaneously under image intensification. Acromioclavicular joint dislocation in children is rare since the distal clavicle does not ossify until the age of 18 or 19 years meaning that almost all closed fractures of the clavicle in children can be treated nonoperatively.

    Post-stroke shoulder pain is associated with either a peripheral or central pathology. However, most of the time, it is challenging to establish a cause-and-effect relationship between the suggested pathology and shoulder pain reported. We report a 66 year-old man who developed a right hemiplegic shoulder pain two months post stroke with initial investigations suggestive of peripheral pathologies. Pharmacological and non-pharmacological treatment did not improve his shoulder pain. Later he developed complex regional pain syndrome (CRPS) of the right hand and the initial shoulder pain subsequently relieved following resolution of the CRPS.
