Balance and motor skills are essential prerequisites for physical development of a child. The aims of this study were to measure anthropometrics, postural balance and motor skills; and examine their correlation among healthy preschool children. Forty nine healthy preschool children aged between 3 to 4 years old participated from PERMATA preschool organization. Pediatric Balance Scale and Peabody Development Motor Scale-2nd Edition (PDMS-2) were administered to measure balance skills for both fine and gross motor skills respectively. Mann-Whitney U test demonstrated that there was no significant difference in balance (p=0.72) and motor skill (p=0.33) between boys and girls. Spearman correlation coefficient demonstrated that there was significant correlation between balance skills with height (r=0.45, p=0.001) and body mass index(r=0.47, p=0.001). No significant correlation was found between balance skills and motor skills (r=0.11, p=0.44). The present study suggests that balance skills in healthy preschool children aged 3-4 years old are correlated with their physical growth such as height and weight but not motor skills.
Clubfoot is associated with leg length inequality, with the affected leg being shorter as a consequence of the hypoplasia. Early treatment of a minimally hypoplastic clubfoot usually allows catchup growth and both legs equalise in length after a few years. Late treatment however is associated with a shortening of the affected foot. A case is described where late treatment of a severe clubfoot is assocated with lengthening of the affected leg.
Living with borderline personality disorder (BPD) involves a lot of emotional suffering which may be hidden behind the complex and controversial nature of the condition and treatment. The condition is still largely under-diagnosed, undertreated and stigmatized. This paper described the emotional battle faced by a patient living with the disorder and the application of psychosocial treatments in helping her to recover.
This short report aims to describe the Circle of Care (COC) Project in Malaysia. This is an example of smart partnership between the Malaysian Psychiatric Association (MPA) and Johnson and Johnson which began in 2003. By means of philanthropic funds from an industrial company, many people have benefited in many different aspects through the project. It consists of three main psychosocial activities: education and support programme for carers and families of people with mental illness; psychosocial rehabilitation for patients with mental illness; and mass education for the people in promoting mental health and prevention of mental health problems and illness. To date, the project has either fully or partially funded hundreds of activities along the line of these three objectives. While there has been growth of psychosocial interventions in the country contributed by the project, it is faced with a few challenges which are becoming the next focus of actions of MPA.
This case series reports four patients who used religion and spirituality to relieve symptoms of post traumatic stress disorder (PTSD) following motor vehicle accidents. Their symptoms subsided after a few weeks and the recovery is sustained after one month. This demonstrates that in a country where psychological help is still scarce and religion is central to its culture, intervention based on spirituality and religion can be used as an alternative early intervention to relieve symptoms of PTSD and hence protects them from developing the condition.
In July 1997 at 7 pm , 49 members 0f the public complained of dizziness, sore throat, eyes irritation and tightness of chest after exposed to sulphur dioxide while traveling on the road about 100 meter 90m the sulphuric acid factory in Teluk Kalong Kemaman. The incident was caused by leaking sulfur dioxide from return pipe of scrubber circulation. tank in the factory. The problem had occurred due to carelessness of the operator to inspect the level of water in the scrubber circulation tank during the operation.
In recent years, there has been concern that non-smokers may also be at risk from secondhand smoke exposure, especially children. This study was done to determine the prevalence of secondhand smoke exposure at home and the association between secondhand smoke exposure and respiratory symptoms among primary schoolchildren in Kota Bharu, Kelantan. This was a comparative cross-sectional study involving children, aged 10·12 years. A structured questionnaire was used to obtain the information on sociodemographic, respiratory symptoms and smokers in the house. A random sample of 10 from 95 primary schools in Kota Bharu was included. Six classes were randomly selected from each school, two classes each from each school year of primary 4·6. A total of 795 children completed the questionnaire during September 2003 till March 2004. 386 of children (48.6%) were boys and 409 children (51.4%) were girls. Most of the children were Malay (99.9%). A total of 442 (55.6%) children lived with at least 1 smoker in the house mainly from the smoking fathers. Significantly increased odds ratios due to secondhand smoke exposure were observed for most of the respiratory symptoms. The odds ratios (95% confidence interval) were 1.67 (1.18, 2.39) for cough in the morning, 1.59 (1.10, 2.30) for cough at night, 1.76 (1.16, 2.65) for cough most days for the previous 3 months, 1.57 (1.14, 2.17) for phlegm in the morning, 1.49 (1.08, Z.07) for phlegm during daytime or at night, 1.38 (1.03, 1.86) for nose problems in the morning, 1.40 (1.03, 1.90) for nose problems at night and 1.78 (1.14, 2.78) for throat problems at night, 1.55 (1.06, 2.26) for ever wheeze or diagnosed asthma by doctor, 1.57 (1.05, 2.36) for throat problems in the morning and 1.81 (1.15, 2.85) for throat problems during daytime. The odds ratios increased with increasing number of smokers at home for cough in the morning, cough most days for the previous 3 months, phlegm in the morning, ever wheeze or diagnosed asthma by doctor, throat problems in the morning, throat problems during daytime and throat problems at night. In view of the significant health risks posed to children by secondhand smoke, public health policies are needed to protect this vulnerable population. The aim of such policies Ls to ensure the right of every child to grow up in an environment free of tobacco smoke.
To describe a quick and simple diagnostic approach to monocular diplopia. Diplopia is a common visual complain in casualty departments, general practice clinics, neurologic clinics as well as ophthalmic clinics. Monocular diplopia, however, is uncommon. Many well established clinical examination methods are available to address diplopia. Some require special equipments which are not easily available or unfamiliar outside of ophthalmic clinic. We describe a simple two-minute diagnostic approach to monocular diplopia. Basic knowledge and understanding of simple clinical examination techniques enhances diagnostic skill and allow proper localization of underlying disorders.
Introduction: A prebiotic such as inulin is a well-known functional plant food ingredient. It is capable of stimulating growth of beneficial bifidobacteria in the intestine thus protecting against intestinal infections, preventing constipation, increasing mineral absorption, reducing the incidence of colon cancer, and producing B vitamins. Inulin added to food therefore has to be stable during food processing especially against heat treatment, low pH and Maillard reaction. Methods: Newly developed dark chocolate, DC-1, containing inulin (replacing sugar component) as an added value, was stored at 18oC, 60% relative humidity and 25oC, 80% relative humidity (RH) to determine shelf life stability compared to control dark chocolate, DC-0 (with high content of sugar). Sensory evaluation (quantitative descriptive analysis), water activity (aw), microbiological content and presence of inulin after storage of the prebiotic chocolate under both conditions were evaluated to determine shelf life. Results: The DC-1 chocolate had at least 12 months of shelf life at 18oC, 60% RH with better acceptance than DC-0; moreover, it did not experience microbiological and inulin content changes. At 25oC, 80% RH, the growth of Aspergillus sp. was observed on the surface of both DC-0 and DC-1 with aw >0.50 after a 2-month storage. Conclusion: Shelf life stability of DC-1 is almost similar to DC-0.
A longitudinal study was conducted to relate basal metabolic rate (BMR) with growth during adolescence. Subjects comprise 70 boys and 69 girls aged between ten and thirteen years at the time of recruitment. Parameters studied include anthropometric measurements and BMR, which was measured by indirect calorimetry using the Deltatrac metabolic monitor. Measurements were carried out serially once every six months, with a total of 713 BMR data points collected over three years. Mean BMR of boys aged 11, 12, 13 and 14 years were 4.96 ± 0.63 MJ/day, 5.28 ± 0.71 MJ/day, 5.73 ± 0.68 MJ/day and 5.92 ± 0.63 MJ/day, respectively; while mean BMR of girls in the 10, 11, 12 and 13 year age groups were 4.96 ± 0.63 MJ/day, 4.85 ± 0.63 MJ/day, 5.05 ± 0.55 MJ/day and 4.94 ± 0.51 MJ/day, respectively. Comparison of measured BMR with BMR values predicted from the FAO/WHO/UNU (1985) equations shows that the predictive equations overestimated the BMR of Malaysian boys by 3% and that of girls by 5%. The Henry & Rees (1991) equations for populations in the tropics underestimated BMR of boys and girls by 1% and 2%, respectively. Linear regression equations to predict BMR based on body weight were derived according to sex and age groups. It is recommended that these predictive equations be used for the estimation of BMR of Malaysian adolescents.
Although lipoma is common in the upper limbs, it rarely occurs in the palm, and usually does not compress the surrounding structures. Here, we report a patient presenting with compressive neuropathy of the ulna and median nerves secondary to a palmar lipoma. Surgical excision led to full neurological recovery.
The consequence of postoperative infections associated with orthopaedic or biomaterial-associated implants is devastating to both the patients and the surgeons. Bacterial microcolonies adhere to the surface of implants, forming biofilms and then detaching part of itself into free-floating planktonic forms may be the cause of recurrent and persistent infections. These bacteria are very resistant towards antibiotics and require a higher drug concentration than usual in order to eradicate them. Quorem-sensing is regarded as one mechanism of communication or integration between these microorganisms in the biofilm and may even be in the transfer of resistant genes. Disruption of this pathway is regarded as one method of inhibiting its growth and formation. Implant design, technique and stability of fixation as well as the surface characteristics, the material and its biocompatibility may also influence bacterial adhesion. It has been suggested that multi-prong strategies such as prevention and disruption of biofilm formation, parenteral antibiotics, use of antibiotic-impregnated construction materials and altering the intrinsic properties of the implant surface may help to eradicate this menace.
The term Developing Nations has to be used with caution as it had traditionally included a wide array of countries outside the developed world of North America, Western Europe and Japan (and a few other countries such as Australia and South Africa). The characteristics which defined these “emerging markets” were a Gross National Product (GNP) per capita which was below that of the developed economies, the potential for market growth and an environment with continued economic and political instability. However, as many of these countries have grown at different rates and have economic and other drivers which are very different and disparate, definitions of this sector have become more fragmented.

Villoglandular papillary adenocarcinoma was first described by Young and Scully in 1989 as a distinct entity with the histological features of exophytic growth proliferation, villous and papillary architecture and mild to moderate nuclear atypia. We report one case of villoglandular papillary adenocarcinoma (VGPA) of the uterine cervix with lymph node metastasis and reviewed the clinicopathological features of six other cases reported in the literature. Our patient is the seventh similar reported cases. They ranged in age from 29 to 54 (mean, 41) years. Five had lymphovascular invasion. All except our patient were treated with radical hysterectomy and radiotherapy. She was followed-up for 7 months and unfortunately died due to chest infection.
Amitraz poisoning is rare and there has been no reported cases in the Malaysian literature. Ingestion of this compound carries many life threatening side effects. We describe a case of Amitraz poisoning in an 18 years old young adult. He developed hypotension, required ventilatory support and a day of intensive care unit stay. He had a quick recovery after he was treated symptomatically and was discharged well after 3 days.
The Malaysian skincare industry is growing rapidly with a vast number of new sunscreens being produced annually. Inadequate skincare regulations and lack of enforcement have resulted in the overrating of sunscreens’ quality. The objectives of this study were to evaluate the efficacy and safety of the local and international sunscreens and to determine the effects of adding concentrated antioxidants into them. Three local and three internationally manufactured sunscreens were tested for the in vitro Ultraviolet A protection factor (UVAPF), Sun Protection Factor (SPF) and photostability. The creams were spread onto roughened polymethylmethacrylate plates where the absorbance was measured using a spectrophotometer before and after two hours of sunlight irradiation. The procedure was repeated combining available concentrated vitamin C and E creams. International sunscreens were found to have more accurate SPF labels (p=0.009) while local sunscreens were found to be more photostable (p=0.003). However, both sunscreens had inadequate UVAPF (p=0.471). Vitamin C enhanced the SPF values (p= 0.04) of both groups of sunscreens while vitamin E enhanced their photostability (p=0.000). Interestingly, combining vitamins C and E rich creams with the sunscreens had no effect on the SPF and UVAPF values as compared to the use of a single vitamin. More importantly, the combination of vitamins decreased the photostability (p=0.002) of sunscreens as compared to the addition of vitamin E alone. In conclusion, photoprotection is best achieved when sunscreens are used together with creams containing either vitamin C or E alone.
The beneficial impact of the differential biofeedback intervention technique on modification in autonomic competence, as well as the ultimate impact on bilateral shooting ability, were studied on young and competitive male soccer players. A total of 45 young high-performing soccer players in the age range of 18 to 24 years were recruited. At first, the players were subjected to baseline evaluation of psychomotor (i.e., reaction time - RT), physiological (viz. resting heart-rate; VO2Max, electrical muscle potentiality, etc.), and psychobiological indices (such as skin conductance components - latency, amplitude and recovery time). Thereafter, they were equally categorized into: Control Group, Experimental Group I [who received skin conductance (Sc) biofeedback training], and Experimental Group II [who received electromyography (EMG) biofeedback intervention training]. Participants of the experimental groups were subjected to their respective interventions (Sc & EMG biofeedback intervention training), which were imparted for 24 sessions (15 mins/day; 2 days/week for 12 weeks). After six weeks of intervention, mid-term evaluation of all of the aforementioned parameters (assessed during baseline evaluation) was performed. Thereafter, intervention sessions continued following the identical protocol for six weeks. At the end of the 12th week, a post-intervention assessment on all of the psychological, psychomotor and psychobiological variables was carried out on all of the participants to verify the effect of training on dependent measures. Post-intervention analyses revealed improvements in physiological, psychobiological and performance parameters, which could be rationally attributed to the differential biofeedback therapeutic interventions introduced to the experimental groups. The outcome suggested that both interventions facilitated improvement in bilateral shooting ability, while indepth analyses clarified that a higher extent of autonomic recovery emerged as the most significant factor facilitating shooting ability in the experimental groups.
The exponential fed-batch cultivation of Bacillus sphaericus UPMB10 in 2 l stirred tank fermenter was performed by feeding the initial batch culture with 14 g l-1 of glycerol according to the algorithm aimed at controlling the specific growth rate (μ) of the bacterium. Very high viable cell count (1.14 x 1010 cfu ml-1), which was four times higher as compared to batch cultivation, was achieved in the fed-batch with a controlled μ at 0.4 h-1. In repeated exponential fed-batch cultivation, consisting of four cycles of harvesting and recharging, a final cell concentration of 1.9 x 1011 cfu ml-1 was obtained at the end of the fourth cycle (46 h). Meanwhile, acetylene reduction of cell samples collected from repeated fed-batch cultivation remained unchanged and was maintained at around 20 nmol C2H2 h-1 ml-1 after prolonged cultivation period, and was comparable to those obtained in batch and exponential fed-batch cultivation. Glycerol could be used as a carbon source for high performance cultivation of B. sphaericus, a nitrogen fixing bacterium, in repeated fed-batch cultivation with high cell yield and cell productivity. The productivity (0.68 g l-1 h-1) for repeated fed-batch cultivation increased about 6 times compared to that obtained in conventional batch cultivation (0.11 g l1 h-1). A innovative method in utilizing glycerol for efficient cultivation of nitrogen fixing bacterium could be beneficial to get more understanding and reference in manipulating the integrated plans for sustainable and profitable biodiesel industry.
The process of etching is the most crucial part of the work of manufacturing printed circuit boards (PCB). In the etching process by nitric acid, a spent etching waste solution of composition 250 g/L HNO3, 30-40 g/L Cu, 30-40 g/L Sn, 30-40 g/L Pb and 20-25 g/L Fe is produced. High metal concentrations in the spent etching waste solution make it a viable candidate for the recovery of metals. Recovery of metals from spent etching waste solution is a significant concern as the recent growth in production of printed circuit boards has generated a drastic increase of spent etching waste solution each year. This study concerns itself with the recovery of metals from spent etching waste. In this study a dilution was made in order to increase the pH of the solution as spent etching waste solution has high acidity, and the electrowinning method was performed to recover metals from the spent etching waste solution. Glassy carbon and platinum were used as cathode and anode in order to investigate the electrodeposition of metals and cyclic voltammetry investigation suggests that the deposition of metals on glassy carbon electrodes occurs at four different overpotentials mainly at -0.15 V, -0.35 V, -0.45 V and -0.75 V. Microscopy observation demonstrates that there is a deposition of metals by applying the potentials in a set of current-time transient study for a duration of 60 seconds and the metals recovered formed as aggregates.
This paper presents investigations into the development of control schemes for end-point vibration
suppression and input tracking of a flexible manipulator. A constrained planar single-link flexible manipulator is considered and the dynamic model of the system is derived using the assumed mode method. To study the effectiveness of the controllers, a Linear Quadratic Regulator (LQR) was initially developed for control of rigid body motion. This is then extended to incorporate a noncollocated PID controller and a feedforward controller based on input shaping techniques to control vibration (flexible motion) of the system. For feedforward controller, positive and modified specified negative amplitude (SNA) input shapers are proposed and designed based on the properties of the system. Results from the simulation of the manipulator responses with the controllers are presented in time and frequency domains. The performances of the control schemes are assessed in terms of level of vibration reduction, input tracking capability and time response specifications. Finally, a comparative assessment of the control techniques is presented and discussed.
