Ann Acad Med Singap, 1986 Jan;15(1):118-21.

Drug eruptions from indeginous medicine is often difficult to diagnosis and confirm. It is known that a number of these now supplied by bomohs and Chinese sinsehs contain known drugs and are dispensed as tablets and capsules. We report 3 cases of adverse drug eruption to "Jamu", a Malay herb. A particular brand, "Jamu Indonesia, Toko Air Pancur", from Johor Bahru, Malaysia, is especially recommended for "sakit pinggang" or backache. The cases occurred between January and February 1985, and all had taken brown kidney shaped tablets. The adverse reactions were moderately severe. Two had erythroderma with hepatitis, and one, Steven Johnson Syndrome. Analysis of this jamu for analgesics led to the discovery of adulteration with phenylbutazone and diazepam. Records from local cases from 1974-1984 showed that 8 other patients, all Chinese had adverse cutaneous eruptions from phenylbutazone, oxybutazone and propyphenazone. The skin manifestations were erythroderma (2 cases), vasculitis (2 cases) and toxic epidermal necrolysis (4 cases). Those with toxic epidermal necrolysis had 100% mortality.

Microalgal carbohydrate is considered one of the potential feedstock for biofuel produced via the bioconversion process. However, the current cultivation process using commercial medium exhibited low biomass production and its carbohydrate productivity which become a bottleneck for sustainable microalgal-carbohydrate-based biofuel production. Thus, the objective of this study is to assess the utilization of industrial waste including molasses and glycerol on the Halochlorella rubescens and Tetraselmis suecica growth as well as its carbohydrate content under different cultivation modes such as autotrophic, heterotrophic and photoheterotrophic conditions. From this study, the highest maximum biomass of H. rubenscens and T. suecica of 0.653 ± 0.009 and 0.669 ± 0.01gL-1 were obtained when the cultivation was performed under photoheterotrophic using molasses. High carbohydrate content of H. rubescens and T. seucica of 56.81 ± 0.39% and 71.52 ± 0.03% with glucose represent the dominant sugar was observed under this condition. The growth kinetic model of the analysis indicated that Huang and Gompertz Models described well the growth of H. rubescens and T. suecica under photoheteroptroph condition with a high significant R2 of 0.99. The information generated could be beneficial for the future development of low-cost microalgal cultivation media formulation for future microalgal carbohydrate-based products such as bioethanol.

The incidence of neurenteric cyst (NC) is rare amongst spine tumors. It is most often asymptomatic but may present
with sensory and motor symptoms. When associated with thoracic vertebra fusion it is not reported before, this complicates the placement of pedicle screw during posterior instrumentation. Herein, we report a case of thoracic spinal
neurenteric cyst in a 40-year-old man that presents with chronic back pain, left lower limb weakness and numbness.
Elective excision of NC over T6-T7 with laminectomy and multilevel posterior instrumentation was successfully
performed with significant improvement of the symptoms. Neurenteric cyst is a rare spinal cord lesion which may
cause permanent neurological sequalae. Complete surgical excision with spine fixation in this case provides good
long-term outcome.

Mushroom cultivation along with the palm oil industry in Malaysia have contributed to large volumes of accumulated lignocellulosic residues that cause serious environmental pollution when these agroresidues are burned. In this study, we illustrated the utilization of lignocellulolytic enzymes from the spent mushroom substrate of Pleurotus pulmonarius for the hydrolysis of palm oil mill effluent (POME). The hydrolysate was used for the production of biohydrogen gas and enzyme assays were carried out to determine the productivities/activities of lignin peroxidase, laccase, xylanase, endoglucanase and β-glucosidase in spent mushroom substrate. Further, the enzyme cocktails were concentrated for the hydrolysis of POME. Central composite design of response surface methodology was performed to examine the effects of enzyme loading, incubation time and pH on the reducing sugar yield. Productivities of the enzymes for xylanase, laccase, endoglucanase, lignin peroxidase and β-glucosidase were 2.3, 4.1, 14.6, 214.1, and 915.4 U g-1, respectively. A maximum of 3.75 g/l of reducing sugar was obtained under optimized conditions of 15 h incubation time with 10% enzyme loading (v/v) at a pH of 4.8, which was consistent with the predicted reducing sugar concentration (3.76 g/l). The biohydrogen cumulative volume (302.78 ml H2.L-1 POME) and 83.52% biohydrogen gas were recorded using batch fermentation which indicated that the enzymes of spent mushroom substrate can be utilized for hydrolysis of POME.

Osong Public Health Res Perspect, 2021 May;12(3):196-199.

PMID: 34102050 DOI: 10.24171/j.phrp.2021.0053

Objective: This cross-sectional study aimed to investigate the eating behaviour of Malaysian children aged 2 to 11 years old during the Movement Control Order (MCO) due to the coronavirus disease 2019 pandemic.

Methods: A total of 204 Malaysian parents of children aged 2 to 11 years old were recruited for this study using a combination of purposive and snowball sampling approaches. Parents were required to fill an online questionnaire hosted on Google Forms, which consisted of socio-demographic characteristics (including child's gender, age, and ethnicity, as well as parental income during the MCO) and a 35-item list from the Children's Eating Behaviour Questionnaire (CEBQ). Data analysis was conducted by further stratifying the children's eating behaviour according to socio-demographic characteristics.

Results: No significant differences were observed in the eating behaviour of the children across age and parental income groups during the MCO. Malaysian Indian children had significantly lower mean scores for the food responsiveness (2.50±0.64) and emotional over-eating (2.13±0.72) subscales than Malaysian Chinese children. Girls had a significantly higher mean score for the slowness in eating subscale during the MCO than boys.

Conclusion: Children's eating behaviour were comparable across socio-demographic characteristics. Nonetheless, the findings of the current study provide an overview of Malaysian children's eating behaviour during the MCO.

Does clinical experience help oncology nursing staff to deal with patient pain better than nurses from other displines? Knowledge and attitudes survey amongst nurses in a tertiary care in Malaysia

Yaakup H, Eng TC, Shah SA

Asian Pac J Cancer Prev, 2014;15(12):4885-91.

PMID: 24998558

BACKGROUND: Successful implementation of pain management procedures and guidelines in an institution depends very much on the acceptance of many levels of healthcare providers.

AIM: The main purpose of this study was to determine the level of knowledge and attitudes regarding pain among nurses working in tertiary care in a local setting and the factors that may be associated with this.

MATERIALS AND METHODS: This cross-sectional research study used a modified version of the Nurses' Knowledge and Attitudes Survey (NKAS) regarding pain. Basic demographic data were obtained for further correlation with the level of pain knowledge.

RESULTS: A total of 566 nurses, 34 male and 532 female, volunteered to participate in this study. The response rate (RR) was 76%, with an overall mean percentage score of 42.7±10.9 (range: 5-92.5). The majority of participants were younger nurses below 40 years of age and more than 70% had worked for less than 10 years (6.6±4.45). Up to 92% had never had any formal education in pain management in general. The total mean score of correct answers was 58.6±9.58, with oncology nursing staff scoring a higher percentage when compared with nurses from other general and critical care wards (63.52±9.27, p<0.045). Only 2.5% out of all participants obtained a score of 80% or greater. The majority of the oncology nurses achieved the expected competency level (p<0.03).

CONCLUSIONS: The present findings give further support for the universal concern about poor knowledge and attitudes among nurses related to the optimal management of pain. The results indicated that neither number of years working nor age influenced the level of knowledge or attitudes of the practising nurses. Oncology nursing staff consistently scored better than the rest of the cohort. This reflects that clinical experience helps to improve attitudes and knowledge concerning better pain management.

PMID: 25279062 MyJurnal DOI: 10.5704/MOJ.1207.009

Total talus dislocation is a rare injury and is commonly accompanied by associated fractures. Common worrisome sequelae are infection, avascular necrosis and post-traumatic arthritis. We report here on a patient who sustained an open total talus dislocation with an ipsilateral medial malleolus fracture. Following early debridement, reduction and a combination of internal and external fixations, early recovery was good with no evidence of avascular necrosis.

Fulltext Chronic osteomyelitis secondary to human bite: a case report

Malays Orthop J, 2012 Nov;6(3):40-1.

PMID: 25279055 MyJurnal DOI: 10.5704/MOJ.1207.003

We report a case of a human bite that was initially inadequately treated and progressed to chronic osteomyelitis, finally resulting in digital amputation. Human bites are seemingly innocuous, but if neglected, may lead to subsequent infection and morbidity. Persistence of symptoms should alert the practitioner to the possibility of infection extending to the soft tissue or bone. Bacteriological studies commonly yield mixed aerobic and anaerobic flora. Early debridement and antibiotic treatment may prevent development of severe soft tissue or bone infection.

Liver isolation in abdominal MRI

Rajasvaran L, Haw TW, Sarker SZ

J Med Syst, 2008 Aug;32(4):259-68.

PMID: 18619090

This work presents a method for liver isolation in magnetic resonance imaging (MRI) abdomen images. It is based on a priori statistical information about the shape of the liver obtained from a training set using the segmentation approach. Morphological watershed algorithm is used as a key technique as it is a simple and intuitive method, producing a complete division of the image in separated regions even if the contrast is poor, and it is fast, with possibility for parallel implementation. To overcome the over-segmentation problem of the watershed process, image preprocessing and postprocessing are applied. Morphological smoothing, Gaussian smoothing, intensity thresholding, gradient computation and gradient thresholding are proposed for preprocessing with morphological and graph based region adjacent list constructed for region merging. A new integrated region similarity function is also defined for region merging control. The proposed method produces good isolation of liver in axial MRI images of the abdomen, as is shown in this paper.

The role of wrist anthropometric measurement in idiopathic carpal tunnel syndrome

Lim PG, Tan S, Ahmad TS

J Hand Surg Eur Vol, 2008 Oct;33(5):645-7.

PMID: 18662961 DOI: 10.1177/1753193408093326

Anthropometric wrist measurement ratios were examined for an association with idiopathic carpal tunnel syndrome (CTS). Wrist measurements were recorded in 67 patients with CTS and in a matched control group of 67 healthy volunteers. The Wrist Ratio (WR) (wrist anterior to posterior dimension/wrist medial-lateral dimension) and the Wrist Palm Ratio (wrist anterior to posterior dimension/palm length) were calculated for each case. We found that a WR of > or =0.70 and a Wrist Palm Ratio of >0.342 were significantly associated with idiopathic CTS.

Bee YT, Haresh KK, Rajibans S

Malays J Nutr, 2008 Mar;14(1):65-77.

PMID: 22691765 MyJurnal

The World Health Organization (WHO), National Cholesterol Education Program Adults Treatment Panel III (NCEP ATP III) and International Diabetes Federation (IDF) have proposed different criteria to diagnose metabolic syndrome (MetS). However, there is no single definition to accurately diagnose MetS. The objective of this study is to estimate the prevalence of MetS using WHO, NCEP ATP III and IDF in the Malaysian community, and to determine the concordance between these definitions for MetS. 109 men and women aged > 30 years participated in the study, and the prevalence of MetS was determined according to the three definitions. Weight, height, body mass index (BMI), waist-hip circumference, blood pressure, blood lipid profile and plasma fasting glucose were measured. In order to determine the concordance between IDF and the other two definitions, the kappa index (κ-test) was used. The prevalence of MetS (95% confidence interval) was 22.9% (22.8-23.1) by IDF definition, 16.5% (16.3-16.9) by NCEP ATP III definition and 6.4% (6.2-6.6) by modified WHO definition. The sensitivity and specificity of IDF against NCEP ATP III were 88.9% and 90.1% respectively, IDF against WHO definition were 85.7% and 81.4%. The κ statistics for the agreement of the IDF definition was 68.3 ± 0.1 with the NCEP ATP III, and 30.5 ± 0.1 with the modified WHO definition. The prevalence of the MetS among respondents using the IDF definition was highest, followed by NCEP ATP III, and finally modified WHO definition. There was a good concordance between the IDF and NCEP ATP III definitions, and a low concordance between IDF and modified WHO definitions.
