Fulltext Proposal for a Radiological Classification System for Carpo-Metacarpal Joint Dislocations with or without Fractures

Pundkare GT, Deshpande SS

Malays Orthop J, 2018 Jul;12(2):42-46.
PMID: 30112128 DOI: 10.5704/MOJ.1807.008

Introduction: Though complex injuries like CarpoMetacarpal (CMC) Joint dislocations represent only 1% of all hand injuries, they have disabling impact on the functional status of patient. There are no reports in the literature classifying disabling complex injuries like CMC joint dislocations presumably because of low incidence. We propose a new classification through retrospective analysis of patients, along with literature search. Materials and Methods: A new classification system has been proposed and designed at our clinical unit and applied to eight patients with CMC joint dislocations. All patients were treated with open reduction with Kirschner wire fixation. At follow-up all these patients were analysed for radiographic assessments and functional scores. Results: The proposed classification identifies three types of dislocations and an additional complex category to supplement any basic type. The direction of dislocation describes the types as Type A: Dorsal, Type B: Volar and Type C: Divergent. Among the eight patients in our study, we had two of Type A, two Type B, three Type B.1, one Type C. 1. These patients had average follow-up of 18 months. The quick DASH score improved from 75.76 at 6 weeks to 1.9 at 18 months. We also did intra-observer and inter-observer reliability which scored 1. Conclusion: Our proposal is a reproducible, simple, comprehensive and practical classification, easily remembered and communicated among colleagues. It is clinically relevant as it helps us in planning surgical management and prognostic evaluation.

Abdul Rahman RA, Rafi F, Hanapiah FA, Nikmat AW, Ismail NA, Manaf H

Rehabil Res Pract, 2018;2018:2071726.
PMID: 30402290 DOI: 10.1155/2018/2071726

Background: Tasks requiring simultaneous mobility and cognition (dual tasks) have been associated with incidence of falls. Although these deficits have been documented in individuals with neurologic disorder, the effect of dual task in children with traumatic brain injury has not been fully explored.
Objective: To investigate the effect of dual-task (dual-motor and dual-cognitive task) conditions on spatiotemporal gait parameters during timed up and go test in children with traumatic brain injury.
Methods and Material: A total of 14 children with traumatic brain injury and 21 typically developing children participated in this case-control study. Functional balance was assessed before the actual testing to predict the risk of falls. Timed up and go test was performed under single-task and dual-task (dual-motor and dual-cognitive task) conditions. Spatiotemporal gait parameters were determined using the APDM Mobility Lab system. The descriptive statistics and t-test were used to analyze demographic characteristics and repeated measure ANOVA test was used to analyze the gait parameters.
Results: Under dual-task (dual-motor and dual-cognitive task) conditions during the timed up and go test, gait performance significantly deteriorated. Furthermore, the total time to complete the timed up and go test, stride velocity, cadence, and step time during turning were significantly different between children with traumatic brain injury and typically developing children.
Conclusions: These findings suggest that gait parameters were compromised under dual-task conditions in children with traumatic brain injury. Dual-task conditions may become a component of gait training to ensure a complete and comprehensive rehabilitation program.

Not all swellings are lymph nodes! A case of subcutaneous panniculitis-like T-cell lymphoma

Tee Evelyn Wy Yap CT, Evelyn Yap WY

Med J Malaysia, 2019 Oct;74(5):441-442.
PMID: 31649225

Subcutaneous Panniculitis-like T-cell Lymphoma (SPTL) is a rare cutaneous neoplasm of mature cytotoxic T cells, first described in 1991 by Gonzalez et al. The incidence of SPTL in Asian countries ranges from 2.3% to 3%. In Malaysia, only 5 cases were reported from 2001 to 2004 in Hospital Kuala Lumpur, Malaysia. SPTL typically presents as skincoloured or erythematous subcutaneous nodules, most often on the extremities and trunk, but it can also involve the face, back and neck. Diagnosis of SPTL is made based on correlation of clinical findings and subcutaneous tissue biopsy along with immunohistochemical staining patterns.

Microenvironmental Interplay Predominated by Beneficial Aspergillus Abates Fungal Pathogen Incidence in Paddy Environment

Fan X, Matsumoto H, Wang Y, Hu Y, Liu Y, Fang H, et al.

Environ Sci Technol, 2019 Nov 19;53(22):13042-13052.
PMID: 31631659 DOI: 10.1021/acs.est.9b04616

Rice fungal pathogens, responsible for severe rice yield loss and biotoxin contamination, cause increasing concerns on environmental safety and public health. In the paddy environment, we observed that the asymptomatic rice phyllosphere microenvironment was dominated by an indigenous fungus, Aspergillus cvjetkovicii, which positively correlated with alleviated incidence of Magnaporthe oryzae, one of the most aggressive plant pathogens. Through the comparative metabolic profiling for the rice phyllosphere microenvironment, two metabolites were assigned as exclusively enriched metabolic markers in the asymptomatic phyllosphere and increased remarkably in a population-dependent manner with A. cvjetkovicii. These two metabolites evidenced to be produced by A. cvjetkovicii in either a phyllosphere microenvironment or artificial media were purified and identified as 2(3H)-benzofuranone and azulene, respectively, by gas chromatography coupled to triple quadrupole mass spectrometry and nuclear magnetic resonance analyses. Combining with bioassay analysis in vivo and in vitro, we found that 2(3H)-benzofuranone and azulene exerted dissimilar actions at the stage of infection-related development of M. oryzae. A. cvjetkovicii produced 2(3H)-benzofuranone at the early stage to suppress MoPer1 gene expression, leading to inhibited mycelial growth, while azulene produced lately was involved in blocking of appressorium formation by downregulation of MgRac1. More profoundly, the microenvironmental interplay dominated by A. cvjetkovicii significantly blocked M. oryzae epidemics in the paddy environment from 54.7 to 68.5% (p < 0.05). Our study first demonstrated implication of the microenvironmental interplay dominated by indigenous and beneficial fungus to ecological balance and safety of the paddy environment.

Fulltext The effectiveness of psychiatric therapy against Malaysian cancer patients with depressive disorders: a systematic review

Amir MC, Mousavi L, Shahizan H

Jurnal Psikologi Malaysia, 2016;31:57-66.

The aim of this study is to compare depression in terms of treatment between psychotherapy and medical approach or to combine these approaches among cancer patients in Malaysia with respect to the cancer categories. It also studies the major prevalence of depressive disorder in the group together with the specialized clinical connection to the health outcomes. The annual incidence of cancer cases in Malaysia is 30,000 at late stage of the disease. We found 17 eligible researches out of 142 articles which most were under designed of cross-sectional or prospective study, and contained 2,523 cancer patients. This study was conducted on systematic electronic review using the databases such as PubMed, Scopus, ScienceDirect, Google Scholar, Wiley Online Library were carried out from the period of time between 2006 and 2015. For data collection purposes, the study goes through the Malaysian articles in English language, in which some of the considered factors were general management principles, cancer level among the depressed patients, the selection of the psychological therapies and the use of antidepressant medication. However, the evidences are still not enough to present an effective diagnostic method for the depressive disorders in cancer patients, and to find a successful antidepressant drug and/or an appropriate psychotherapy in this group of patients. Hence, many different approaches could be presented for psychotherapy. In conclusion, we found increased hazard rates for the cancer death among psychiatric patients compared to the control group without a registered mental illness.

Mental health in policing has been widely studied but incidence of mental health illnesses among them keep increasing. This study aimed to analyse generic and specific work stressors among police officers and their differences between urban and sub-urban police population. Methods: This was a cross-sectional study conducted in Kuala Lumpur and in nine sub-urban provinces in Pahang and Negeri Sembilan which involved 328 traffic police officers recruited by universal sampling. Data was collected by using self-administered questionnaire consisted of Police Stress Questionnaire (PSQ), the Job Content Questionnaire (JCQ), the Work Family Conflicts (WFC), the International Union against Tuberculosis and Lung Disease (IUATLD), and the General Health Questionnaire (GHQ-12). Results: The response rate was 71.30%. Majority of respondents were male (86.59%) with average age of 38.84 years old. The prevalence of probable mental health illnesses was 29.80% in sub-urban and 44.30% in urban. Job demand, role ambiguity, family to work conflicts and almost all specific works stressors were significantly higher among urban respondents. For urban, results showed that the most significant stressor was perceived air pollution (p

The potential of endophytic bacteria as a biological control agent for ganoderma disease In oil palm

Nur Rashyeda Ramli, Maizatul Suriza Mohamed, Idris Abu Seman, Madihah Ahmad Zairun, Nasyaruddin Mohamad

Sains Malaysiana, 2016;45:401-409.

This study was conducted to screen the endophytic bacteria as a biological control agent (BCA) against Ganoderma boninense. A total of 581 endophytic bacteria were successfully isolated from symptomless oil palm root tissues at Teluk Intan, Perak, Malaysia. Three endophytic bacteria, Pseudomonas aeruginosa GanoEB1, Burkholderia cepacia GanoEB2, and Pseudomonas syringae GanoEB3 were found to have a potential as BCA based on their percentage inhibition of radial growth (PIRG) in dual culture and culture filtrate tests. Two nursery trials were conducted to evaluate the capability of these bacteria to suppress Ganoderma disease in oil palm seedlings that were artificially infected with G. boninense using rubber wood block (RWB) sitting technique. The percentage of disease incidence (DI), severity of foliar symptoms (SFS) and dead seedlings were used as the assessment tools. As a result, DI and SFS have developed much slower in the seedlings that were pre-treated with bacteria compared to untreated seedlings. After 6 months of inoculation, Ganoderma disease incidence was reduced from 62-75% in the seedlings treated with P. aeruginosa GanoEB1, followed by B. cepacia GanoEB2 (31-59%) and P. syringae GanoEB3 (30-31%). Among these three endophytic bacteria, P. aeruginosa GanoEB1 was the most effective in controlling Ganoderma disease and the dead seedlings were in the range of 13.3-26.7%, followed by B. cepacia GanoEB2 (33.3% for both trials) and P. syringae GanoEB3 (33.3-40.0%) compared to untreated seedlings at 60% for both trials. A field study needs to be conducted to verify their effectiveness in controlling Ganoderma in oil palm.

Incidence of escherichia coli O157:H7 in Thailand

Pharanai Sukhumungoon

Sains Malaysiana, 2015;44:261-267.

Enterohemorrhagic Escherichia coli (EHEC) especially serotype O157:H7 is one of the important food-borne pathogens because it is able to produce crucial toxins Shiga. However, the outbreak of this organism in Thailand has not been reported. Antibody to O157 antigen was detected in some Thai populations and Shiga toxin-producing E. coli were detected in low numbers of clinical specimens. Interestingly, some E. coli that showed positive to O157 fimbriae probe and lack of virulence gene were isolated from certain patients and one isolate of E. coli O157:H7 which possessed stx1, stx2v was detected in a normal child. In addition, the incidence of E. coli O157:H7 strains were monitored by the samples from cattle and retail beef in Thailand although their inability to produce toxins or produce in a low concentration was demonstrated. This review discusses the incidences of E. coli O157 in clinical and environmental samples of Thailand including the transmission possibility of this bacterium across the Thai border through food trade.

Fulltext Impact of population aging on the presentation of out-of-hospital cardiac arrest in the Pan Asian Resuscitation Outcomes Study

Tagami T, Tanaka H, Shin SD, Ma MH, Ko PC, Karim S, et al.

Acute medicine & surgery, 2019 05 22;7(1):e430.
PMID: 31988755 DOI: 10.1002/ams2.430

Aim: As a population ages, it can impact on the characteristics and outcomes of cardiogenic out-of-hospital cardiac arrest (OHCA) patients. This study aimed to evaluate the relationship between the age incidence of cardiogenic OHCA and population aging.
Methods: This was a post-hoc analysis of the Pan Asian Resuscitation Outcomes Study (PAROS) database. Data on the population old-age dependency ratio (i.e. elderly/non-elderly) were extracted from publicly accessible sources (United Nations and World Health Organization).
Results: We analyzed 40,872 OHCA cases from seven PAROS countries over the period 2009 to 2013. We found significant correlation between the population old-age dependency ratio and elderly/non-elderly ratio in OHCA patients (r = 0.92, P = 0.003). There was a significant correlation between the population old-age dependency ratio and risk differences of 30-day survival rates for non-elderly and elderly OHCA patients (r = 0.89, P = 0.007).
Conclusions: Our findings suggest that the proportion of elderly among OHCA patients will increase, and outcomes could increasingly differ between elderly and non-elderly as a society ages progressively. This has implications for planning and delivery of emergency services as a society ages.

Fulltext Bilateral Asymmetrical Fracture Dislocation of Shoulder with Rare Combination of Injuries after Epileptic Seizure: A Case Report

Sharma A, Jindal S, Narula MS, Garg S, Sethi A

Malays Orthop J, 2017 Mar;11(1):74-76.
PMID: 28435581 DOI: 10.5704/MOJ.1703.011

The incidence of bilateral gleno-humeral joint dislocation is rare, is almost always posterior and is usually caused by sports injuries, epileptic seizures, electrical shock, or electroconvulsive therapy. Bilateral fracture-dislocation is even rarer, with a few cases reported in the literature. We report an unusual case with dislocation of the both glenohumeral joints in opposite direction after a seizure episode, with fracture of greater tuberosity on one side and of the lesser tuberosity on the contralateral side. Although there have been a few reports of bilateral asymmetric fracture dislocations of the shoulder in the past, an injury pattern resembling our case has, to the best of our knowledge, not been described in the literature so far. This report includes a detailed discussion regarding the mechanism of injury in a case of asymmetrical dislocation following a seizure episode. At final follow-up, the patient had healed fractures, painless near normal range of motion with no redislocations.

Fulltext Curcumin Nanoformulations for Colorectal Cancer: A Review

Wong KE, Ngai SC, Chan KG, Lee LH, Goh BH, Chuah LH

Front Pharmacol, 2019;10:152.
PMID: 30890933 DOI: 10.3389/fphar.2019.00152

Colorectal cancer (CRC) is the third most prevalent form of cancer, after lung cancer and breast cancer, with the second highest death incidence. Over the years, natural compounds have been explored as an alternative to conventional cancer therapies such as surgery, radiotherapy, and chemotherapy. Curcumin, an active constituent of turmeric has been associated with various health benefits. It has gained much attention as an anticancer agent due to its ability to regulate multiple cell signaling pathways, including NF-κB, STAT3, activated protein-1 (AP-1), epidermal growth response-1 (Egr-1), and p53, which are crucial in cancer development and progression. Nevertheless, the clinical application of curcumin is greatly restricted because of its low water solubility, poor oral absorption, and rapid metabolism. These issues have led to the development of curcumin nanoformulations to overcome the limitations of the compound. Nanotechnology-based delivery systems have been widely used in improving the delivery of poorly-water soluble drugs. Besides, these systems also come with the added benefits of possible cellular targeting and improvement in cellular uptake. An ideal improved formulation should display a greater anticancer activity compared to free curcumin, and at the same time be non-toxic to the normal cells. In this review, we focus on the design and development of various nanoformulations to deliver curcumin for use in CRC such as liposomes, micelles, polymer nanoparticles, nanogels, cyclodextrin complexes, solid lipid nanoparticles (SLN), phytosomes, and gold nanoparticles. We also discuss the current pre-clinical and clinical evidences of curcumin nanoformulations in CRC therapy, analyse the research gap, and address the future direction of this research area.

Choi IY

Plant Dis, 2011 Feb;95(2):227.
PMID: 30743439 DOI: 10.1094/PDIS-05-10-0371

This study was conducted to identify the causal organism of bark dieback disease of highbush blueberry (Vaccinium corymbosum L.) observed in Korea. Blueberry, a woody plant that is native to North America, belongs to the family Ericaceae and genus Vaccinium. Of the 400 species of blueberry in the world, most are distributed in the tropics of Malaysia and Southeast Asia. Highbush blueberry is abundantly grown in Canada and the United States and has become a popular commercial crop in Korea for products such as jam, wine, and sauce. Bark dieback disease of blueberry was found in Sunchang (<5% incidence), Jeollabuk-do, Korea in July 2009. Typical symptoms of the disease were blight and dieback on the stems with lesions extending along entire branches. Morphological examination revealed that the perithecia were of the globose type with a nipple, 155 to 490 (374.6) μm, and brown on the dead bark. Asci were bitunicate and clavate or cylindrical with dimensions of 63 to 125 × 16 to 20 μm and containing eight ascospores. Ascospores were of the long ovoid type with dimensions of 13.2 to 23.7 (17.98) × 25.4 to 41.1 (33.21) μm. From extracted genomic DNA, the internal transcribed spacer (ITS)-5.8S ribosomal DNA region was amplified with universal primers ITS1 (5'-TCCGTAGGTGAACCTGCGG-3') and ITS4 (5'-TCCTCCGCTTATTGATATGC-3'). A BLAST search of GenBank with the ITS sequence revealed that the Sunchang isolate (GenBank Accession No. HQ384217) had 99 to 100% sequence identity with the following Botryosphaeria dothidea accessions: FJ517657, AJ938005, FJ478129, FJ171723, and AJ938004. Phylogenetic analysis with the Sunchang isolate, B. dothidea strains, and related species revealed that the B. dothidea isolate and strains comprised a monophyletic group distinguished from other Botryosphaeria spp. including B. ribis, B. parva, B. protearum, B. lutea, B. australis, B. rhodina, B. obtuse, and B. stevensii (2). On the basis of morphological and molecular results, the isolate was identified as B. dothidea (Moug.) Ces. & De Not. A culture of B. dothidea isolate was grown on potato dextrose agar (PDA) for 10 days. A 5-mm plug was inoculated into stem wounds created with a No. 2 cork borer in 20 2-year-old disease-free blueberry plants grown in a greenhouse. Six plants inoculated with only PDA plugs served as noninoculated controls. The wounds were covered with Parafilm. After 3 months, the Parafilm was removed and black lesions were observed at the fungal inoculation sites, while no lesion was observed on the control plants. To complete Koch's postulates, the fungus was reisolated from the lesions and confirmed to be B. Dothidea (1). There is an urgent need to determine the spread of this disease in Korea, estimate the losses, and develop methods for reducing damage through biological and eco-friendly cultural control methods.

Colorectal cancer (CRC) is a cancer of the large intestine with high mortality and morbidity rate. According to
the Malaysian National Cancer Registry Report, CRC was reported as the second most frequent cancer after
breast cancer. This study was conducted to evaluate the knowledge and perception of IIUM Kuantan Campus
students regarding CRC. Currently, there is no national screening program conducted by the Ministry of
Health Malaysia for CRC as an early prevention in Malaysia. Despite the increase in incidence and mortality
rates of CRC, emphasis on creating awareness regarding CRC among Malaysian is still lacking. Using
convenience sampling method and adapted self-administered questionnaires, this cross-sectional study was
conducted among the undergraduate students of International Islamic University Malaysia, Kuantan Campus.
Overall, more than half of the respondents have a moderate level of knowledge and perceptions regarding
CRC. Moreover, there was a significant difference between male and female respondents in terms of

Fulltext Psychosocial factors, depression, and musculoskeletal disorders among teachers

Ng YM, Voo P, Maakip I

BMC Public Health, 2019 Feb 26;19(1):234.
PMID: 30808335 DOI: 10.1186/s12889-019-6553-3

BACKGROUND: One of the occupations that suffer from musculoskeletal disorders (MSD) is the teaching profession. Although teachers are known to have a variety of health and safety issues, few studies have actually been published that relate to somatic health problems of teachers, especially studies conducted in Malaysia. From this viewpoint, it is clearly important to investigate psychosocial factors, and MSD with depression as mediator among school teachers.
METHODS: The study aimed to determine the incidence of MSD for school teachers in 15 primary schools in Kuala Lumpur during a 6-month period. Secondly, the study also sought to examine the relationships between psychosocial factors, depression and MSD among teachers. Thirdly, the study aimed to explore depression as mediator. The hypothesis addressed by this cross-sectional study was that depression would prove to be a mediator for the psychosocial factors affecting MSD.
RESULTS: The incidence of MSD during the previous 6 months was 80.1% (95% CI: 75.8-84.2%), with 80.5% of female and 77.5% of male teachers reporting symptomatic pain during that period. There were significant relationships between psychosocial factors, depression, and MSD. The results indicated that in relation to psychosocial factors, depression (r = - 0.25, p

Knowledge and practice concerning some aspects of diarrhoeal disease among Orang Asli children 0-5 years, Kuala Langat District

Yahya B, Md Naim AK

Family Physician, 1992;4:17-19.

A cross-sectional study was conducted in four Orang Asli settlements, in the district of Kuala Langat, to determine the knowledge and practice associated with diarrhoeal disease among the Orang asli children (0-5 years). It was seen that the social and environmental factors of the settlements were poor. Only 26% of the households had sanitary latrines and 36% had access to safer water supplies. Ninety-five percent of them had monthly income below the national poverty line. The diarrhoeal incidence was high, ie 240/1000 and the most affected were the older children in the age group of 49 - 60 months. Knowledge of diarrhoeal disease was poor. But the majority (84.2%) knew that breast feeding is the best milk for the child in order to avoid diarrhoeal disease.

First Report of Gray Leaf Spot on Pepper Caused by Stemphylium solani in Malaysia

Nasehi A, Kadir JB, Abidin MAZ, Wong MY, Ashtiani FA

Plant Dis, 2012 Aug;96(8):1227.
PMID: 30727084 DOI: 10.1094/PDIS-03-12-0262-PDN

Symptoms of gray leaf spot were first observed in June 2011 on pepper (Capsicum annuum) plants cultivated in the Cameron Highlands and Johor State, the two main regions of pepper production in Malaysia (about 1,000 ha). Disease incidence exceeded 70% in severely infected fields and greenhouses. Symptoms initially appeared as tiny (average 1.3 mm in diameter), round, orange-brown spots on the leaves, with the center of each spot turning gray to white as the disease developed, and the margin of each spot remaining dark brown. A fungus was isolated consistently from the lesions using sections of symptomatic leaf tissue surface-sterilized in 1% NaOCl for 2 min, rinsed in sterile water, dried, and plated onto PDA and V8 agar media (3). After 7 days, the fungal colonies were gray, dematiaceous conidia had formed at the end of long conidiophores (19.2 to 33.6 × 12.0 to 21.6 μm), and the conidia typically had two to six transverse and one to four longitudinal septa. Fifteen isolates were identified as Stemphylium solani on the basis of morphological criteria described by Kim et al. (3). The universal primers ITS5 and ITS4 were used to amplify the internal transcribed spacer region (ITS1, 5.8, and ITS2) of ribosomal DNA (rDNA) of a representative isolate (2). A 570 bp fragment was amplified, purified, sequenced, and identified as S. solani using a BLAST search with 100% identity to the published ITS sequence of an S. solani isolate in GenBank (1). The sequence was deposited in GenBank (Accession No. JQ736024). Pathogenicity of the fungal isolate was tested by inoculating healthy pepper leaves of cv. 152177-A. A 20-μl drop of conidial suspension (105 spores/ml) was used to inoculate each of four detached, 45-day-old pepper leaves placed on moist filter papers in petri dishes (4). Four control leaves were inoculated similarly with sterilized, distilled water. The leaves were incubated at 25°C at 95% relative humidity for 7 days. Gray leaf spot symptoms similar to those observed on the original pepper plants began to develop on leaves inoculated with the fungus after 3 days, and S. solani was consistently reisolated from the leaves. Control leaves did not develop symptoms and the fungus was not reisolated from these leaves. Pathogenicity testing was repeated with the same results. To our knowledge, this is the first report of S. solani causing gray leaf spot on pepper in Malaysia. References: (1) S. F. Altschul et al. Nucleic Acids Res. 25:3389, 1997. (2) M. P. S.

Prathibha B, Reddy PP, Anjum MS, Monica M, Praveen BH

Dent Res J (Isfahan), 2019 2 13;16(1):36-41.
PMID: 30745917

Background: The aim of this study is comparing the retention and caries preventive effect of the glass-ionomer fissure sealant and resin-based fissure sealant.
Materials and Methods: A randomized-controlled split-mouth study was conducted to compare the retention and the caries preventive effect of light-cured resin-based sealant (3M ESPE) and glass ionomer sealant (Fuji VII). The sealants were applied to either the right or the left lower mandibular molars (7-9 yrs of age) in 120 school children, based on the randomization process. They were recalled for assessment of clinical retention at intervals of 3, 6, and 12 months. The caries-preventive effect between the two materials was tested statistically by the McNemar's test for matched pairs, and the differences observed with regard to the retention of the materials was tested by Chi-square tests. The level of significance was set to be at P < 0.05.
Results: At the end of 12th month, sealant retention is found to be higher in the resin-based sealant group compared to the glass ionomer group. In the glass ionomer sealants placed, 101 (91%) were caries-free and 10 (9%) had caries. In the resin-based sealant, 105 (94.60%) had sound teeth and 6 (5.4%) had dental caries (P = 0.34).
Conclusion: The glass ionomer sealant was less retentive when compared to resin sealants. The caries incidence between the glass ionomer and resin-based sealants was not statistically significant.

The prevalence and incidence rate of hypertension among Orang Asli had been increasing due to
modernization and assimilation of outside practices such as intake of high cholesterol food, alcohol, and
smoking. Orang Asli utilize their herbs or plants to treat some illness due to the factor of logistics and the
knowledge on these nature resources since decades ago that is carried out from their ancestors. In this review
paper, hypertension genes of Orang Asli in Peninsular Malaysia and the utilization of ethno-medicinal plants
in reducing the clinical manifestation in hypertension were deliberated. There are quite a number of related
hypertensive genes particularly in renin-angiotensin-aldosterone system (RAAS) playing a pivotal role in
pathogenesis of hypertension. A genome-wide association studies showed potential candidate genes in
hypertension among Orang Asli in Peninsular Malaysia. However there is yet molecular study on these genes
among Orang Asli with their unique genetic profile. Noteworthy information on mechanism of ethnomedicine in treating hypertension are scarce, even the efficacy of modern medicine in treating hypertension
on Orang Asli are rare. Therefore, study on efficacy of ethno-medicine plant by Orang Asli and the
regulation effect on hypertension genes are needed to be further explored and elucidated.

First Report of Curvularia lunata on Red-Fleshed Dragon Fruit (Hylocereus polyrhizus) in Malaysia

Hawa MM, Salleh B, Latiffah Z

Plant Dis, 2009 Sep;93(9):971.
PMID: 30754569 DOI: 10.1094/PDIS-93-9-0971C

Red-fleshed dragon fruit (Hylocereus polyrhizus [Weber] Britton & Rose) is a newly introduced and potential crop in the Malaysian fruit industry. Besides its nutritious value, the fruit is being promoted as a health crop throughout Southeast Asia. In April of 2007, a new disease was observed in major plantations of H. polyrhizus throughout five states (Kelantan, Melaka, Negeri Sembilan, Penang, and Perak) in Malaysia with 41 and 25% disease incidence and severity, respectively. Stems of H. polyrhizus showed spots or small, circular, faint pink-to-beige necrotic lesions that generally coalesced as symptoms progressed. Symptom margins of diseased stem samples were surface sterilized with a 70% alcohol swab, cut into small blocks (1.5 × 1.5 × 1.5 cm), soaked in 1% sodium hypochlorite (NaOCI) for 3 min, and rinsed in several changes of sterile distilled water (each 1 min). The surface-sterilized tissues were placed onto potato dextrose agar (PDA) and incubated under alternating 12-h daylight and black light for 7 days. A fungus was consistently isolated from the stems of symptomatic H. polyrhizus and identified as Curvularia lunata (Wakker) Beodijn (1-3) that showed pale brown multicelled conidia (phragmoconidia; three to five celled) that formed apically through a pore (poroconidia) in sympodially, elongating, geniculated conidiophores. Conidia are relatively fusiform, cylindrical, or slightly curved, with one of the central cells being larger and darker (26.15 ± 0.05 μm). All 25 isolates of C. lunata obtained from diseased H. polyrhizus are deposited at the Culture Collection Unit, Universiti Sains Malaysia and available on request. Isolates were tested for pathogenicity by injecting conidial suspensions (1 × 106 conidia/ml) and pricking colonized toothpicks on 25 healthy H. polyrhizus stems. Controls were treated with sterile distilled water and noncolonized toothpicks. All inoculated plants and controls were placed in a greenhouse with day and night temperatures of 30 to 35°C and 23 to 30°C, respectively. Development of external symptoms on inoculated plants was observed continuously every 2 days for 2 weeks. Two weeks after inoculation, all plants inoculated with all isolates of C. lunata developed stem lesions similar to those observed in the field. No symptoms were observed on the control plants and all remained healthy. C. lunata was reisolated from 88% of the inoculated stems, completing Koch's postulates. The pathogenicity test was repeated with the same results. To our knowledge, this is the first report of C. lunata causing a disease on H. polyrhizus. References: (1) M. B. Ellis.

INTRODUCTION: In this era of globalization, urbanization, and rapidly expanding unhygienic food corners across the globe, the incidence of food poisoning is very common nowadays.
AIM: The aim of our study was to investigate the perceptions and readiness of schoolteachers to accept notifications on food poisoning as a part of education to the students.
METHODOLOGY: A descriptive cross-sectional study was carried out with the help of a validated questionnaire for data collection. Our research involved schoolteachers from both primary and secondary schools in Muar. The questionnaire was pretested among the eligible trainee teachers and yielded an internal consistency reliability coefficient (c = Cronbach's alpha) of 0.082. This study was conducted from October 29, 2017, to December 14, 2018, in Muar. Our sample size was 259. Ethical consent was obtained from the Institution Ethical Committee.
RESULTS: A total of 259 schoolteachers from both primary and secondary schools in Muar were included in this study. In our study, 81.1% of the teachers responded that they can easily educate their students about food poisoning. Most of them (93.1%) were ready to receive notifications on food poisoning in any mode, and about 72% of the teachers preferred WhatsApp as their mode of receiving notification. The least (1.2%) preferred mode of notification was LINE (a social app). Teachers' willingness to disseminate the information regarding food poisoning was also higher (98.5%).
CONCLUSIONS: We concluded that majority of the schoolteachers had a good perception and were ready to receive the notifications on food poisoning through WhatsApp as a part of education to the students.
