    Many operations have been described for the correction of claw hands following involvement in leprosy, from Sir Harold Stiles (1922) of Edinburgh, through Bunnell, Brand and many others in India and USA. Some of these procedures are classified "static" and attempt mainly to correct hyper-extension at the metacarpo-phalangeal joint, while the "dynamic" procedures employ a variety of tendon graft operations to restore the function of the paralysed lumbrical muscles. This study is an analysis of the four-tailed tendon graft operation of Paul Brand, carried out in the National Leprosy Con. trol Centre, Sungei Buloh, Selangor, during the period 1965·175, by a host of surgeons, mainly by Dr M.K. Bhojwani, MRCP, FRCSEd, the Director of the Centre at that time. The analysis carried out during November. December 1976, was made on 36 hands in 33 patients; it revealed an average improvement in the metacarpo. Phalangeal joint flexion of nearly 90% and in the proximal interphalangeal joint extension in nearly 80%, and an improvement in the grafted lumbrical voluntary motor tone of nearly 70%.

    The provision of the most suitable rehabilitation treatment for stroke patient remains an ongoing challenge for clinicians. Fully understanding the pathomechanics of the upper limb will allow doctors to assist patients with physiotherapy treatment that will aid in full arm recovery. A biomechanical study was therefore conducted using the finite element (FE) method. A three-dimensional (3D) model of the human wrist was reconstructed using computed tomography (CT)-scanned images. A stroke model was constructed based on pathological problems, i.e. bone density reductions, cartilage wane, and spasticity. The cartilages were reconstructed as per the articulation shapes in the joint, while the ligaments were modelled using linear links. The hand grip condition was mimicked, and the resulting biomechanical characteristics of the stroke and healthy models were compared. Due to the lower thickness of the cartilages, the stroke model reported a higher contact pressure (305 MPa), specifically at the MC1-trapezium. Contrarily, a healthy model reported a contact pressure of 228 MPa. In the context of wrist extension and displacement, the stroke model (0.68° and 5.54 mm, respectively) reported a lower magnitude than the healthy model (0.98° and 9.43 mm, respectively), which agrees with previously reported works. It was therefore concluded that clinicians should take extra care in rehabilitation treatment of wrist movement in order to prevent the occurrence of other complications. Graphical abstract ᅟ.

    Skin detection has gained popularity and importance in the computer vision community. It is an essential step for important vision tasks such as the detection, tracking and recognition of face, segmentation of hand for gesture analysis, person identification, as well as video surveillance and filtering of objectionable web images. All these applications are based on the assumption that the regions of the human skin are already located. In the recent past, numerous techniques for skin colour modeling and recognition have been proposed. The aims of this paper are to compile the published pixel-based skin colour detection techniques to describe their key concepts and try to find out and summarize their advantages, disadvantages and characteristic features.

    Due to the outbreak of the COVID-19 pandemic, practicing personal hygiene such as frequent hand sanitising has become a norm. The making of effective hand sanitiser products should follow the recommended formulations, but the high demand worldwide for such affordable products could have made them a candidate for counterfeiting, thus deserving forensic determination and profiling for source determination or supply chain tracing. In this study, determination and discrimination of hand sanitisers was carried out by employing attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy combined with chemometrics. Fifty commercially available hand sanitisers were obtained from the market and analysed. ATR-FTIR profiles of each sanitiser were compared and decomposed by principal component analysis (PCA) followed by linear discriminant analysis (LDA). Physical observation enabled the discrimination of seven samples based on their respective colours, the presence of beads and their colours, and the physical forms of formulations. Subsequently, eight distinct patterns were observed through visual comparison of ATR-FTIR profiles of the remaining 43 samples. An initial unsupervised exploratory PCA model indicated the separation of two main groups with ATR-FTIR profiles similar to those of ethanol and isopropanol, respectively. The PCA score-LDA model provided good predictions, with a 100% correct classification into eight different groups. In conclusion, this study demonstrated a quick determination and discrimination of hand sanitiser samples, allowing screening for any restricted components and sample-to-sample comparison.

    k-nearest neighbour (k-NN) has been shown to be an effective learning algorithm for classification and prediction. However, the application of k-NN for prediction and classification in specific sport is still in its infancy. The present study classified and predicted high and low potential archers from a set of physical fitness variables trained on a variation of k-NN algorithms and logistic regression. 50 youth archers with the mean age and standard deviation of (17.0 ± 0.56) years drawn from various archery programmes completed a one end archery shooting score test. Standard fitness measurements of the handgrip, vertical jump, standing broad jump, static balance, upper muscle strength and the core muscle strength were conducted. Multiple linear regression was utilised to ascertain the significant variables that affect the shooting score. It was demonstrated from the analysis that core muscle strength and vertical jump were statistically significant. Hierarchical agglomerative cluster analysis (HACA) was used to cluster the archers based on the significant variables identified. k-NN model variations, i.e., fine, medium, coarse, cosine, cubic and weighted functions as well as logistic regression, were trained based on the significant performance variables. The HACA clustered the archers into high potential archers (HPA) and low potential archers (LPA). The weighted k-NN outperformed all the tested models at itdemonstrated reasonably good classification on the evaluated indicators with an accuracy of 82.5 ± 4.75% for the prediction of the HPA and the LPA. Moreover, the performance of the classifiers was further investigated against fresh data, which also indicates the efficacy of the weighted k-NN model. These findings could be valuable to coaches and sports managers to recognise high potential archers from a combination of the selected few physical fitness performance indicators identified which would subsequently save cost, time and energy for a talent identification programme.

    Support Vector Machine (SVM) has been shown to be an effective learning algorithm for classification and prediction. However, the application of SVM for prediction and classification in specific sport has rarely been used to quantify/discriminate low and high-performance athletes. The present study classified and predicted high and low-potential archers from a set of fitness and motor ability variables trained on different SVMs kernel algorithms. 50 youth archers with the mean age and standard deviation of 17.0 ± 0.6 years drawn from various archery programmes completed a six arrows shooting score test. Standard fitness and ability measurements namely hand grip, vertical jump, standing broad jump, static balance, upper muscle strength and the core muscle strength were also recorded. Hierarchical agglomerative cluster analysis (HACA) was used to cluster the archers based on the performance variables tested. SVM models with linear, quadratic, cubic, fine RBF, medium RBF, as well as the coarse RBF kernel functions, were trained based on the measured performance variables. The HACA clustered the archers into high-potential archers (HPA) and low-potential archers (LPA), respectively. The linear, quadratic, cubic, as well as the medium RBF kernel functions models, demonstrated reasonably excellent classification accuracy of 97.5% and 2.5% error rate for the prediction of the HPA and the LPA. The findings of this investigation can be valuable to coaches and sports managers to recognise high potential athletes from a combination of the selected few measured fitness and motor ability performance variables examined which would consequently save cost, time and effort during talent identification programme.

    We have all heard the old aphorism, "Necessity is the mother of invention." While the provenance of the proverb is uncertain, its truth is not in doubt. This is true for the development of hand surgery in Malaysia. As part of the management for leprosy, patients with high ulnar nerve palsies were managed by the pioneers of hand surgery in Malaysia. They did tendon transfers to improve the quality of life of these patients. Since then, hand surgery in Malaysia have grown leaps and bounds. From a small humble beginning in the suburb of Sungai Buloh to organizing the 10th Congress of Asian Pacific Federation of Societies for Surgery of the Hand, hand surgery in Malaysia will only get better with time.

    We report a 21-year old female patient who presented with an 18-month history of a swelling in the distal phalanx of her right little finger. Although the history, clinical features and MRI were suggestive of a benign tumour or a tuberculous lesion, the histo-pathological examination of the swelling was reported as a conventional osteosarcoma. Osteosarcoma of the hand is very rare. This article highlights the possibility of a seemingly benign lesion seen in a routine clinic could well turn out to be malignant, and the need to maintain a high index of suspicion.

    Splinter or foreign body removal from the hand and foot is a common occurrence. Usually only the deep seated, broken or missed splinters are referred to the surgeon for removal. Unless the object is radio-opaque, plain radiograph will not give any useful information, hence removal can sometimes be very difficult and traumatic. We are reporting a case where a radiolucent splinter was removed with the aid of ultrasonography. This modality can help to localize a splinter at the pre and intra-operative period, minimizing amount of exploration and time of operation.

    From July through December 1997, 11 previously healthy children in Peninsular Malaysia succumbed to an illness clinically characterised by an acute severe refractory left-ventricular failure, following a brief prodromal illness, in the midst of an outbreak of hand, foot and mouth disease (HFMD), similar to the reported experience in Sarawak and Taiwan. Retrospective reviews of the clinical features and results of laboratory, pathological and virological investigations of cases were conducted. The median age of the 11 case-patients was 31 months (range, 13 to 49 months); 6 were males. A brief prodromal illness of 3 days (range, 2 to 5 days) was characterised by fever (axillary temperature > 38 degrees C) (100%), oral ulcers (72%), extremity rashes (45%) and significant vomiting (55%). Upon hospitalisation, 7 of 11 case-patients had features suggestive of cardiogenic shock, while 4 of 11 case-patients developed shock during hospitalisation as evidenced by marked sustained tachycardia (heart rate > or = 180 beats per minute), poor peripheral pulses and peripheral perfusion, mottled extremities, pulmonary oedema (haemorrhagic pulmonary secretions in 8 of 11 cases during tracheal intubation, often precipitated by conservative crystalloid boluses, and radiographic evidence of acute pulmonary oedema in 5 of 7 cases) and markedly impaired left ventricular function on echocardiographic examination (7 of 7 cases). Three of 4 case-patients had aseptic meningitis while one case-patient also had an acute flaccid paraparesis. Despite supportive therapy, death occurred within a median of 13.4 hours following hospitalization. Post-mortem findings (all 8 specimens examined) consistently demonstrated brain-stem encephalitis with foci of neuronal necrosis and micro-abscesses. None of the 11 specimens examined revealed histological evidence of myocarditis. Enterovirus 71 (EV71) was detected in 10 of 11 case-patients, many (7) from various sterile tissue sites (5 from central nervous tissues). No other viruses were isolated or identified. Clinical features and pathological studies closely paralleled the reported experience in Sarawak and Taiwan. The uniform necropsy findings of necrotizing brain-stem encephalitis coupled with essentially normal myocardial histology, in concert with the concurrent and consistent detection of EV71 points to a primary EV71 encephalitis; as yet unclear neurogenic mechanisms may account for the cardiovascular manifestations.

    BACKGROUND: Brain plasticity is an important factor in prosthesis usage. This plasticity helps with brain adaptation to learn new movement and coordination patterns needed to control a prosthetic hand. It can be achieved through repetitive muscle training that is usually very exhausting and often results in considerable reduction in patient motivation. Previous studies have shown that a playful concept in rehabilitation can increase patient engagement and perseverance.

    OBJECTIVE: This study investigated whether the inclusion of video games in the upper limb amputee rehabilitation protocol could have a beneficial impact for muscle preparation, coordination, and patient motivation among individuals who have undergone transradial upper limb amputation.

    METHODS: Ten participants, including five amputee participants and five able-bodied participants, were enrolled in 10 1-hour sessions within a 4-week rehabilitation program. In order to investigate the effects of the rehabilitation protocol used in this study, virtual reality box and block tests and electromyography (EMG) assessments were performed. Maximum voluntary contraction was measured before, immediately after, and 2 days after interacting with four different EMG-controlled video games. Participant motivation was assessed with the Intrinsic Motivation Inventory (IMI) questionnaire and user evaluation survey.

    RESULTS: Survey analysis showed that muscle strength and coordination increased at the end of training for all the participants. The results of Pearson correlation analysis indicated that there was a significant positive association between the training period and the box and block test score (r8=0.95, P

    Hand, foot and mouth disease (HFMD) is a common illness of infants and young children <10 years of age. It is characterized by fever, ulcers in the oral cavity, and rashes with blisters that appear on the palm and sole. The most common causal agents of HFMD are coxsackievirus A16 (CV-A16) and human enterovirus 71 (HEV71), but other enteroviruses, including CV-A5 and CV-A10, can also cause it. When caused by CV-A16 infection, it is usually a mild disease, and patients normally recover without requiring any special medical attention.

    INTRODUCTION: Hospital-acquired infection is still one of the health problems in the world that require infection control and prevention efforts, especially nurses' hand washing compliance. Various strategies and efforts to improve handwashing compliance include educational approaches, motivation and improvement of the health care system, one of which is through the use of The Theory Of Planned Behaviour application in solving handwashing compliance.

    MATERIALS AND METHODS: Quantitative research with a survey approach and observation of hand washing compliance of all nurses N = 321 with a sample of n = 178 nurses. The research variables studied consisted of intention, discipline, self-assessment, opportunity compliance and implementation of the nurse's hand washing. Nurse handwashing compliance observations were made by Infection Prevention Control Link Nurse (IPCN) committee. Data analysis using structural equation modelling (SEM) with smart partial least square (SmartPLS 3.0) application.

    RESULTS: The nurse's intention to apply the theory of planned behaviour has no significant effect on the implementation of hand washing with path coefficients of 0.104 and p-value 0.221 > 0.05. The effect of nurses' intentions on the implementation of nurse hand washing through discipline is significant with a value of variance accounted for (VAF) 0.8043 or 80.43 % of nurse discipline is a complete mediation variable.

    CONCLUSION: Discipline as a complete meditation variable in the application of the theory of planned behaviour in the compliance of nurses' hand washing five moments six steps. Nurses are expected to continuously improve their discipline independently or be assisted by training activities facilitated by the hospital.

    Exercise has been suggested as the best and the most affordable way for managing blood pressure. The insertion/ deletion of angiotensin I-converting enzyme (ACE) I/D gene polymorphism had been reported to be linked with sev- eral diseases such as hypertension and diabetic nephropathy. Several studies showed that blood pressure response to exercise training for health management also vary among individuals with different genotypes of ACE I/D gene poly- morphism. A study of 9 months of endurance exercise training at 75 to 85 % of VO2max showed that the decrease of resting blood pressure in I allele carriers wass greater than D allele carriers. In contrast, other study discovered that adult women with D allele had greater reduction in resting blood pressure than those with I allele, following a 12-week combined aerobic and resistance exercise training. Despite the inconsistencies of some findings, it has remained unknown if the ACE I/D gene polymorphism would also influence blood pressure response to isometric handgrip training that had been found to be superior to the dynamic resistance exercise training in controlling and preventing high blood pressure. Thus, this article was to review the literature on ACE I/D gene polymorphism and blood pressure response to exercise training that could serve as the basis for future research to identify individuals who will lower resting blood pressure the most with exercise training program for health management.

    The purpose of this study was to investigate the relationship between anthropometric and motor performance and to determine the contribution of combined anthropometric dimensions on motor performance. A total of 225 male (n = 138) and female (n = 87) Malaysian university athletes aged
    between 18 and 28 years (M = 22.1, SD = 1.8) from 18 different team related sports and individual sports participated in this study. The subjects underwent anthropometric measurements (height, weight, BMI,% body fat, waist-hip ratio) and motor performance tests (grip strength - GS, back
    strength - BS, 7 level sit-up - SU7, 10m sprint - S10, 30m sprint - S30, sit and reach - SR, trunk extension test - TE, SEMO agility test - SEMO, vertical jump - VJ, standing long jump - SLJ, reaction time (audio) - RTa, reaction time (visual) - RTv, bleep test - Bleep, leg strength - LS, stork test– ST, and push-ups - PU). Descriptive analysis showed that anthropometric and performance difference between sports reflected the needs and requirements of the sports. Multivariate Analysis of Covariance (MANCOVA) and multiple regression analysis showed that height, weight, BMI, % body fat, waist-hip ratio contributed positively or negatively on specific components of motor performance. Among male athletes, all anthropometric were found to be a significant contributor to strength, vertical jump, cardiovascular endurance, while among females, only % body fat and WHR contributed significantly to abdominal strength, vertical jump and trunk extension. Findings of the study suggested that anthropometric characteristics that contributed to motor performance should provide a scientific rationale in selecting and training of athletes.

    Introduction: Microsurgery is a subspecialised field which requires high technical skill. Laboratory training offers good opportunity for novice surgeons to learn and repetitively practise their skills prior to hands-on clinical practice. Commonly, the training programme consists of models in a stepwise increase in fidelity: from latex sheet to anaesthetised rat. We introduce microgrids model as a daily warm up procedure in a 5-day basic microsurgery course. The purpose of this study is to evaluate the correlation between microgrids colouring under magnification with microsuturing proficiency among novice surgeons. Materials and Methods: Participants were required to fill in microgrids under magnification everyday during their 5-day training as a starter test. The number of completely filled in microgrids in 20 seconds was recorded. A simulated cut on latex sheet was sutured and the time taken to apply five sutures was recorded. The sutures were evaluated with modified Global Rating Scale (GRS). Data was analysed with SPSS. Results: There was a statistically significant correlation between the number of microgrids coloured and the time taken to apply five sutures (p<0.01). An increase in number of microgrids coloured was significantly associated with the increase in quality of the suturing technique (p< 0.01). During the 5-day basic microsurgery skills training for novice surgeons, microsuturing skill improvement correlated with microgrid colouring. Conclusion: Microgrids colouring reflected microsuturing proficiency. It is an inexpensive, readily available, and simple model of 'warm up' for hand dexterity. The microgrids model can function as a starter test for initial training and a quick screening measure to assess microsurgical skill.
