    Chromoblastomycosis is a chronic subcutaneous mycosis seen mainly in tropical regions. While malignant transformation rarely occurs, the present report describes a 69-year-old man with a 21-year history of chromoblastomycosis complicated by invasive squamous cell carcinoma requiring amputation of the affected limb. A review of previous reported cases shows malignancy arising after 20-30 years of infection in ≥60-year-old males who have received inadequate treatment of chromoblastomycosis and have had relapses. An immunocompromised state is not an associated feature of such cases. The extremities are commonly affected as carcinomas occur from the most chronic lesions which are generally found on these limbs.

    Hand hygiene is the topmost crucial procedure to prevent hospital-acquired infections. Choosing an effective hand disinfectant is necessary in enforcing good hand hygiene practice especially in hospital settings. The aim of the study was to investigate the efficacy of Aaride AGT-1 as a hand disinfectant for the inhibition of pathogenic microorganisms' transmission among both patients and personnel in the health care system compared to other commercially available disinfectants. In the present study, a new hand disinfectant Aaride AGT-1 was tested against several bacterial and viral pathogens to evaluate its antimicrobial activity profile. The results revealed that Aaride AGT-1 displayed the highest antibacterial activity against five pathogenic bacteria including MRSA when compared to other commercially available hand sanitizers. Aaride AGT-1 showed the lowest percentage needed to inhibit the growth of bacterial pathogens. In addition, results obtained from time killing assay revealed that Aaride AGT-1 demonstrated the best killing kinetics, by eradicating the bacterial cells rapidly within 0.5 min with 6 log reduction (>99.99% killing). Also, Aaride AGT1 was able to reduce 100% plaque formed by three viruses namely HSV-1, HSV-2 and EV-71. In conclusion, Aaride AGT-1 is capable of killing wide-spectrum of pathogens including bacteria and viruses compared to other common disinfectants used in hospital settings. Aaride AGT-1's ability to kill both bacteria and viruses contributes as valuable addition to the hand disinfection portfolio.

    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.

    Lack of parking space has become major contributing factor to traffic congestion
    which may affect the environmental condition due to incalculable amounts of wasted
    fuel and carbon emission. Congestion and parking are interrelated as looking for
    parking space may create additional delay and impair local circulation. The proposed
    automatic parking system which embedded with radio frequency identification (RFID)
    and internet of things (IoTs) module will introduce a monitoring platform for the
    parking space. This intelligent parking system makes it possible for the drivers to
    obtain information beforehand through their mobile hand phone application or any
    display available. This paper describes the mechanical design of automatic indoor
    parking space with the advancement of sensor networks application known as RFID.
    The design criterias were studied to develop a parking prototype which dealing with
    number of degree of freedom as well as movement mechanism. The result presented
    at the end of this paper was evaluated from the engineering analysis using the
    developed parking prototype to meet system performance as well as design safety
    factor.

    This paper presents an auto grasping algorithm of a proposed robotic gripper. The purpose is to enhance the grasping mechanism of the gripper. Earlier studies have introduced various methods to enhance the grasping mechanism, but most of the works have not looked at the weight measurement method. Thus, with this algorithm, the weight of the object is calculated based on modified Wheatstone Bridge Circuit (WBC) which is controlled by programmable interface controller (PIC) method. Having this approach introduces and improves the grasping mechanism through an auto grasping algorithm. Experimental results show that an auto grasping algorithm based on pressure sensor measurements leads to a more precise grasping measurement and consequently enhance the sensitivity measurement as well as accurate movement calibration. Furthermore, several different grasping objects based on the proposed method are examined to demonstrate the performance and robustness of our approach.

  6. Plasma cholinesterase screening
    Goh CS
    Family Practitioner, 1986;9:40-42.
    The plasma cholinesterase baseline levels in Malaysian workers are within the guidelines used. There is a need to carry out close monitoring of workers handling organophosphate s even in a well-run, modern factory where there are no hazards in the plant operation. Abnormal results are mainly because many of our workers are unaware of the health hazards and do not follow orders properly, ie personal hygiene, such as washing of hands before eating, etc. The use of temporary workers should be discouraged because of poor compliance with rules and difficulty in follow up. Product stewardship and education of farmers, sprayers and end users are of paramount importance. Finally there is a great need for educaiton of everyone from factory workers, farmers, sprayers to the general public.

  7. Emerging and re-emerging diseases: The migrant factor. [Abstract]
    Khairul Anuar A
    JUMMEC, 2002;7:14-14.
    Many nation states, including Malaysia are undergoing development and modernization while modernization brings tremendous achievements related to social and economic wellbeing, on the other hand, it also brings along with it the various untoward effects on the nation. One of the main factors which have an impact on modernization seems to be the rapid changes in the demographic pattern. In the initial stage of modernization, mass migration of rural populations to the urban areas, has been on going in Malaysia since the seventies. In the early nineties, the robust economic development in Malaysia necessitated the import of foreign labour from the neighbouring countries in order to provide cheap labour in the labour intensive industries. This demographic changes, internal and foreign migration, parallels the economic progress of the host countries. According to the latest report from the Immigration Department, there are more than 1.2 million registered foreign workers (up to January 1998) in Malaysia. This figure may exceed 2 million if we take into consideration the illegal immigrants and this is a big proportion (about 10%) of foreign workers in which has Malaysia's population of approxiamtely 20 million. The presence of such a big number of foreign workers during less than a decade is not merely an immigration issue, but it is a major concern for the nation especially with respect to health care, housing and education. As the immigrant community is highly dynamic, the emerging and re-emerging infectious diseases are a great concern for Malaysia especially in formulating health policies for Malaysia currently and in the future.

  8. Osteoporosis in Parkinson's Disease: Relevance of Distal Radius Dual-Energy X-Ray Absorptiometry (DXA) and Sarcopenia
    Tan YJ, Lim SY, Yong VW, Choo XY, Ng YD, Sugumaran K, et al.
    J Clin Densitom, 2020 07 30;24(3):351-361.
    PMID: 32888777 DOI: 10.1016/j.jocd.2020.07.001
    Osteoporotic fractures are common in Parkinson's disease (PD). Standard dual-energy X-ray absorptiometry (DXA) measuring bone mineral density (BMD) at the femoral neck and lumbar spine (central sites) has suboptimal sensitivity in predicting fracture risk in the general population. An association between sarcopenia and osteoporosis in PD has not been studied. We compared BMD and osteoporosis prevalence in PD patients vs controls; determined the osteoporosis detection rates using central alone vs central plus distal radius DXA; and analyzed factors (in particular, sarcopenia) associated with osteoporosis. One hundred and fifty-six subjects (102 patients with PD, 54 spousal/sibling controls) underwent femoral neck-lumbar spine-distal radius DXA. Seventy-three patients and 46 controls were assessed for sarcopenia using whole-body DXA and handgrip strength. Patients underwent clinical and serum biochemical evaluations. PD patients had significantly lower body mass index compared to controls. After adjustment for possible confounders, distal radius BMD and T-scores were significantly lower in PD patients compared to controls, but not at the femoral neck/lumbar spine. With distal radius DXA, an additional 11.0% of patients were diagnosed with osteoporosis (32.0% to 43.0%), vs 3.7% in controls (33.3% to 37.0%) additionally diagnosed; this increase was largely driven by the markedly higher detection rate in female PD patients. Female gender (adjusted odds ratio [ORadjusted] = 11.3, 95% confidence interval [CI]: 2.6-48.6) and sarcopenia (ORadjusted = 8.4, 95% CI: 1.1-64.9) were independent predictors for osteoporosis in PD. Distal radius DXA increased osteoporosis detection, especially in female PD patients, suggesting that diagnostic protocols for osteoporosis in PD could be optimized. A close association between osteoporosis and sarcopenia was documented for the first time in PD, which has important implications for clinical management and future research.

    PMID: 34857224 DOI: 10.1016/j.clnesp.2021.08.039
    BACKGROUND & AIMS: Sarcopenia has been shown associated with functional decline, disability, poorer quality of life and mortality. However, there are limited studies among hospitalised cardiac patients in Malaysia. This study aimed to identify the association of sarcopenia and type 2 diabetes mellitus (T2DM) with clinical outcomes among hospitalised cardiac patients.

    METHODS: This prospective observational study assessed 100 patients who were admitted to the general wards at the National Heart Institute. We measured handgrip strength, body composition using bioelectrical impedance analysis (BIA) and recorded the length of stay (LOS), unplanned readmission and incidence of infection within 90 days after discharge.

    PMID: 24763843
    Melorheostosis is a rare, progressive bone disease accompanied by hyperostosis and soft tissue fibrosis. While affected adults present with contracture and pain, children present with limb length discrepancy and deformity. We report the case of a 20-year-old woman with melorheostosis since childhood who presented with right hand deformity and numbness. Radiographs showed not only a combination of dense sclerosis and opacities, but also the classic 'flowing candle wax' appearance. Radiography can be used to identify melorheostosis, thus preventing unnecessary bone biopsies. Carpal tunnel release revealed the presence of a thickened flexor retinaculum and a degenerated median nerve distal to the retinaculum, but did not show hyperostosis. This case highlights the role of nerve decompression in melorheostosis and the importance of early identification of the disease to prevent unnecessary bone biopsies.

    INTRODUCTION: Hand strength is a good indicator of physical fitness and frailty among the elderly. However, there are no published hand strength references for Malaysians aged > 65 years. This study aimed to establish normative data for hand grip strength (HGS) and key pinch strength (KPS) for Malaysians aged ≥ 60 years, and explore the relationship between hand strength and physical ability.

    METHODS: Healthy participants aged ≥ 60 years with no neurological conditions were recruited from rural and urban locations in Malaysia. HGS and KPS were measured using hand grip and key pinch dynamometers. Basic demographic data, anthropometric measures, modified Barthel Index scores and results of the Functional Reach Test (FRT), Timed Up and Go (TUG) test and Jebsen-Taylor Hand Function Test (JTHFT) were recorded.

    RESULTS: 362 subjects aged 60-93 years were recruited. The men were significantly stronger than the women in both HGS and KPS (p < 0.001). The hand strength of the study cohort was lower than that of elderly Western populations. Significant correlations were observed between hand strength, and residential area (p < 0.001), FRT (r = 0.236, p = 0.028), TUG (r = -0.227, p = 0.009) and JTHFT (r = -0.927, p < 0.001).

    CONCLUSION: This study established reference ranges for the HGS and KPS of rural and urban elderly Malaysian subpopulations. These will aid the use of hand strength as a screening tool for frailty among elderly persons in Malaysia. Future studies are required to determine the modifiable factors for poor hand strength.

    PMID: 35062533 DOI: 10.3390/s22020574
    A real-time Bangla Sign Language interpreter can enable more than 200 k hearing and speech-impaired people to the mainstream workforce in Bangladesh. Bangla Sign Language (BdSL) recognition and detection is a challenging topic in computer vision and deep learning research because sign language recognition accuracy may vary on the skin tone, hand orientation, and background. This research has used deep machine learning models for accurate and reliable BdSL Alphabets and Numerals using two well-suited and robust datasets. The dataset prepared in this study comprises of the largest image database for BdSL Alphabets and Numerals in order to reduce inter-class similarity while dealing with diverse image data, which comprises various backgrounds and skin tones. The papers compared classification with and without background images to determine the best working model for BdSL Alphabets and Numerals interpretation. The CNN model trained with the images that had a background was found to be more effective than without background. The hand detection portion in the segmentation approach must be more accurate in the hand detection process to boost the overall accuracy in the sign recognition. It was found that ResNet18 performed best with 99.99% accuracy, precision, F1 score, sensitivity, and 100% specificity, which outperforms the works in the literature for BdSL Alphabets and Numerals recognition. This dataset is made publicly available for researchers to support and encourage further research on Bangla Sign Language Interpretation so that the hearing and speech-impaired individuals can benefit from this research.

    PMID: 24893027
    Hand, foot and mouth disease (HFMD) is endemic in Sarawak, Malaysia. In this study, a geographical information system (GIS) was used to investigate the relationship between the reported HFMD cases and the spatial patterns in 11 districts of Sarawak from 2006 to 2012. Within this 7-years period, the highest number of reported HFMD cases occurred in 2006, followed by 2012, 2008, 2009, 2007, 2010 and 2011, in descending order. However, while there was no significant distribution pattern or clustering in the first part of the study period (2006 to 2011) based on Moran's I statistic, spatial autocorrelation (P = 0.068) was observed in 2012.

    Oral-facial-digital syndrome type 1 (OMIM #311200) is an X-linked dominant, developmental disorder. Among the 13 described clinical variants of oral-facial-digital syndrome, oral-facial-digital syndrome type 1 is of significance to dermatologists due to presence of congenital milia and hypotrichosis, not described in other variants. Since oral-facial-digital syndrome type 1 is genetically a distinct entity, awareness of these features help to clinically delineate this from other variants.

    Grip strength is an important measure used to monitor the progression of a condition, and to evaluate outcomes of treatment. We assessed how various physical and social factors predict normal grip strength in an adult Malaysian population of mixed Asian ethnicity (254 men, 246 women). Grip strength was recorded using the Jamar dynamometer. The mean grip strength for the dominant hand was 29.8 kg for men and 17.6 kg for women. Multiple regression analysis demonstrated that the dominant hand grip strength was positively associated with height and body mass index, and negatively associated with age for both sexes. Dominant hand grip strength was related to work status for men (p

    Electrocution is one of the rarest modes of suicide. In this case, one school going adolescent committed suicide by electrocution using bare electric wire. This is a rare case of suicidal death by applying live wires around the wrists, simulating the act of judicial electrocution. He positioned himself on armed chair and placed the nude wire loops from a cable around both wrists and switched on the current by plugging in to nearest socket by foot. There were linear electric contact wounds completely encircling around the both wrists. In addition to these linear electric burns all around wrists, there were electrical burns over both hands. This death highlights the need of supervision and close watch on children for self-destructing activities and behavior. This case also highlights unusual method adopted by adolescent to end his life.

    J Cachexia Sarcopenia Muscle, 2016 12;7(5):535-546.
    PMID: 27104109
    BACKGROUND: The measurement of handgrip strength (HGS) has prognostic value with respect to all-cause mortality, cardiovascular mortality and cardiovascular disease, and is an important part of the evaluation of frailty. Published reference ranges for HGS are mostly derived from Caucasian populations in high-income countries. There is a paucity of information on normative HGS values in non-Caucasian populations from low- or middle-income countries. The objective of this study was to develop reference HGS ranges for healthy adults from a broad range of ethnicities and socioeconomically diverse geographic regions.

    METHODS: HGS was measured using a Jamar dynamometer in 125,462 healthy adults aged 35-70 years from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study.

    RESULTS: HGS values differed among individuals from different geographic regions. HGS values were highest among those from Europe/North America, lowest among those from South Asia, South East Asia and Africa, and intermediate among those from China, South America, and the Middle East. Reference ranges stratified by geographic region, age, and sex are presented. These ranges varied from a median (25th-75th percentile) 50 kg (43-56 kg) in men <40 years from Europe/North America to 18 kg (14-20 kg) in women >60 years from South East Asia. Reference ranges by ethnicity and body-mass index are also reported.

    CONCLUSIONS: Individual HGS measurements should be interpreted using region/ethnic-specific reference ranges.
