    Sains Malaysiana, 2017;46:1679-1685.
    Acanthaceae merupakan famili tumbuhan angiosperma di bawah order Lamiales yang terdiri daripada sekurang-kurangnya 4000 spesies sama ada spesies tropika atau subtropika. Spesies daripada famili ini ditemui di pelbagai habitat dan mempunyai pelbagai morfologi serta corak taburan geografi. Walau bagaimanapun, maklumat mengenai ciri anatomi bagi Acanthaceae masih dangkal sehingga ke hari ini. Objektif kajian ini ialah untuk mengenal pasti jenis trikom yang hadir pada permukaan epidermis adaksial dan abaksial sepal dan juga petal bunga bagi beberapa spesies terpilih daripada Acanthaceae di Semenanjung Malaysia. Kajian ini melibatkan pengumpulan sampel di lapangan, penyediaan spesimen baucer, teknik kajian epidermis petal, cerapan di bawah mikroskop cahaya dan juga cerapan di bawah mikroskop imbasan elektron. Tiga puluh jenis trikom dicerap dalam kajian ini dan daripada jumlah tersebut, 23 jenis trikom dicerap hadir pada permukaan epidermis petal manakala 17 jenis trikom dicerap hadir pada permukaan epidermis sepal. Jenis trikom yang direkodkan ialah trikom ringkas unisel dan ringkas multisel, trikom kelenjar kapitat dan kelenjar peltat serta juga trikom berlengan. Keputusan kajian ini menunjukkan kehadiran dan jenis trikom pada permukaan sepal dan petal mempunyai nilai taksonomi yang berguna untuk tujuan pembezaan dan pengecaman spesies. Maklumat ciri morfologi trikom yang diperoleh daripada kajian ini merupakan maklumat baharu ciri anatomi bunga bagi Acanthaceae.

    Ainul Mardhiyah Mohd Razib, Goh TL, Nur Amanina Mazlan, Muhammad Fahmi Abdul Ghani, Tuan Rusli Tuan Mohamed, Abdul Ghani Rafek, et al.
    Sains Malaysiana, 2018;47:1413-1421.
    The stability of the limestone cliff at Gunung Kandu, Gopeng, Perak, Malaysia was assessed based on the Slope Mass
    Rating (SMR) system on 53 cross sections of the Gunung Kandu hill slopes. The slopes of Gunung Kandu were identified
    as class I (very good) to IV (poor). The kinematic analysis showed that 12 out of 53 hill slopes of Gunung Kandu were
    identified as having potential wedge, planar and toppling failures. The assessment showed that the stability of the western
    flanks can be classified as stable to unstable with the probability of failure from 0.2 to 0.6. The stability of the eastern and
    southern flanks range from very stable to partially stable with the probability of failure from 0.0 to 0.4. While the stability
    of northern flanks are from very stable to stable with the probability of failure of 0.0 - 0.2. This systematic approach
    offers a practical method especially for large area of rock slope stability assessment and the results from probability of
    failure values will help engineers to design adequate mitigation measures.

  7. Once-daily aminoglycoside dosing
    Riley PA
    JUMMEC, 1996;1:17-19.
    The conventional use of aminoglycoside antibiotics has several disadvantages including the need for regular pre- and post-dose assaying and the risks of toxicity. Achieving a therapeutic and non-toxic serum concentration may be difficult in many patients especially those with severe sepsis. Correct timing of doses and assays is essential, but this is often difficult to achieve. Many of these difficulties may be remedied by the use of once daily dosing. This dosing schedule appears to be equally effective as the conventional method and i s also less toxic. There are many other advantages including the need for less assays and venepuncture resulting in reduced costs. KEYWORDS: Aminoglycosides, antibiotic therapy, toxicity, therapeutic monitoring

  10. Investigation of a recurrent case of salmonellosis due to Salmonella bovismorbificans and Salmonella matopeni using pulsed-field gel electrophoresis analysis and antibiograms
    Thong KL, Puthucheary S, Boey CCM, Pang T
    JUMMEC, 1999;4:103-109.
    A restropective study on a case of recurent salmonellosis in a 3 month old child due to Salmonella bovismorbificans and Salmonella matopeni was carried out using pulsed field gel electrophoresis (PFGE) and antibiotic susceptibility analysis. PFGE clearly distinguished the two serovars and that the recurrent infection was shown to associated with variant forms of Salmonella bovismorbificans. The chromosomal changes detected among the seqential isolates of Salmonella bovismorbificans appeared to be associated with varing antibiogram patterns. The study also showed that the recurrent infection in the patient could be related to prolonged antibiotic therapy. KEYWORDS: Recurrent salmonellosis, PFGE typing, Antibiograms, Salmonella bovismorbificans.

  11. A case of chronic fatigue syndrome in Malaysia
    Zainal NZ
    JUMMEC, 2000;5:103-104.
    A case of chronic fatigue syndrome (CFS) like illness was identified recently. Diagnosis CFS is commonly used in the western countries but not in Malaysia or other parts of Asia. It is probably because the diagnosis of neurasthenia has gradually disappeared especially in the United States and United Kingdom. Neurasthenia is dropped in the DSM-111 and DSM-1V but is still retained in the 10th International Classification of Disease. This paper is reporting the case and discussing the definition of chronic fatigue syndrome. (JUMMEC 2000; 2:103-104).

  12. Anticholinergic exacerbation of psychotic symptoms: a case report
    Gill JS, Jambunathan ST, Muhsin M, Abdul Rashid R
    JUMMEC, 2005;8:61-62.
    A common practice in psychiatry when treating patients is the concurrent administration of anticholinergics along with antipsychotics, either to prevent or treat extrapyramidal syndrome reactions from occurring. However, most antipsychotics have inherent anticholinergic properties themselves. Therefore, this subtype of these patients have a higher than usual risk of developing anticholinergic side-effects, of which the central nervous manifestations can mimic psychosis, and may cloud judgement on patients’ progress towards their treatment.

  13. A prospective audit of Desflurane anaesthesia in the University of Malaya Medical Centre Day Surgery Unit
    Chiu CL, Mansor M, Wang CY
    JUMMEC, 2005;8:45-49.
    We evaluated the use of Desflurane anaesthesia in this prospective observational audit in the University of Malaya Medical Centre Day Surgery Unit. Fifty ASA I-II unpremedicated day surgery patients received fentanyl and propofol induction after preoxygenation. Desflurane was introduced initially at 2% and the concentration was increased gradually to 4%, then 6%, 8% and 10% in nitrous oxide and oxygen. Patients breathed spontaneously throughout the surgery. Desflurane was switched off at the end of surgery and patients breathed 100% oxygen. The haemodynamic effect, perioperative complications and recovery profiles were recorded. Systolic arterial pressure and heart rate decreased after induction of anaesthesia but returned to baseline value at discharge. Adverse airway event such as coughing and postoperative nausea and vomiting are two unwanted complications. KEYWORDS: Desflurane, day surgery, propofol induction

  14. Sexual health of male migrant workers
    Siti Norazah Z
    JUMMEC, 2002;1:52-58.
    Sexual health is defined as part of reproductive health and includes healthy sexual development; equitable and responsible relationships and sexual fulfillment; and freedom from illness, disease, disability, violence and other harmful practices related to sexuality. For this project on Health Problems of Migrant Workers, a section on sexual health was incorporated based on a special concern over sexually transmitted diseases (STDs), and high-risk behaviours. Access to healthcare is recognised to be a problem with minority or marginalised groups, including adolescents and migrant populations, especially undocumented migrants. This exacerbates the issue of control and management of STDs. The Sexual Health section covered experience with sexual interourse, and a limited number of questions related to sex partners and condom use among those who are sexually experienced.

  15. Fulltext The effects of virgin coconut oil on postmenopausal osteoporotic bone: analyses on osteoblastogenesis and antioxidant genes. [Tindakan minyak kelapa dara terhadap tulang osteoporosis pascamenopaus: analisis gen osteoblastogenesis dan antioksidan]
    Shidqiyyah Abdul-Hamid, Norliza Muhammad, Isa Naina Mohamed
    Sains Malaysiana, 2016;45(12):1815-1822.
    Postmenopausal osteoporosis is one of the main health problems in aging women. It was due to several factors including oxidative stress, which can be controlled through intake of antioxidants from food sources. Virgin coconut oil (VCO) is one of the natural product rich in antioxidants and has been proven to protect osteoporotic bone. This study was conducted to gain in-depth understanding on virgin coconut oil’s activity on osteoporosis at molecular level. Thirty two female Sprague-Dawley rats were divided into four groups, namely Sham operated group, ovariectomized control group (Ovx+Ctrl), ovariectomized with VCO treatment (Ovx+VCO), and ovariectomized with estrogen treatment (Ovx+E). All treatments were administered orally for ten weeks. Bone samples were obtained to examine changes on expression of superoxide dismutase (SOD), glutathione peroxidase (GPX), osteocalcin and runt-related transcription factor 2 (Runx2) genes. The results indicated that rats receiving VCO treatment had experienced significant increments in SOD, GPX and osteocalcin gene expressions compared to the ovariectomized control group, besides the gene expressions of Runx2 which also showed an increment pattern. In conclusion, VCO helps to protect bone in osteoporotic rat model by increasing the expressions of antioxidant genes and genes which increase the osteoblast acitivities.

  16. Fulltext Landslide factors and susceptibility mapping on natural and artificial slopes in Kundasang, Sabah
    Sharir K, Roslee R, Lee KE, Simon N
    Sains Malaysiana, 2017;46:1521-1540.
    This study was carried out on the hilly topographic area in Kundasang, Sabah. This area is known to be extremely prone to landslides that occurred either naturally or by human interference to natural slopes. Aerial photographs interpretation was conducted in order to identify landslide distributions across three assessment years (2012, 2009 and 1984). These datasets were classified into two landslides groups based on their occurrences; natural and artificial. A total of 362 naturally occurring landslides were identified and another 133 are artificial slope landslides. Physical parameters which include lithology, slope angle, slope aspect and soil series were analyzed with each landslide group to examine the different influence of these parameters on each of the group. From the analysis, the landslide density for the natural landslide group shows that more than 35° slope angle and slope aspect facing east and southwest are prone to landslides. In terms of geological materials, high landslide density is recorded in the phyllite, shale, siltstone and sandstone lithologies group and the Pinosuk, Kepayan and Trusmadi soil series. In contrast, for the artificial
    slope landslide, high landslide density is observed in the 25°-35° slope angle and similar density in every slope aspect classes. The geological materials however have similar landslide density across their factors’ classes. The landslide density technique was also used to generate the landslide susceptibility maps for both landslide conditions. Validation of the maps shows acceptable accuracy of 71% and 74%, respectively, for both natural and artificial slope landslide susceptibility maps and this shows that these maps can be used for future land use planning.

    Raja Lexshimi R, Siti Mariam B, Rohaizak M, Subahan M, Nabishah M
    Malaysian Journal of Public Health Medicine, 2017;17(1):14-23.
    The type of specific learning needs of women with breast cancer using the Information Needs Questionnaire (INQ) had been identified prior to developing a breast cancer education package. It is also important to determine the types of patient factors such as demographic and clinical factors that influence women’s specific learning needs on breast cancer. This study thus reports the findings on what type of patient factors influence women’s specific learning needs related to the types of INQ. A total of 140 women with breast cancer who sought treatment at Universiti Kebangsaan Malaysia Medical Centre participated in this cross sectional study. Age showed a significant relationship with specific learning needs on sexual attractiveness (p=0.001) and self-care (p=0.048). Duration of illness was related to information on spread of breast cancer (p=0.040) and self-care (p=0.047). Education level showed a significant relationship with cure (p=0.001), sexual attractiveness (p=0.007) and spread of breast cancer (p=0.003). Occupation showed a significant relationship with specific learning needs on sexual attractiveness (p=0.005), chemotherapy (p=0.043), radiotherapy (p=0.039) and hormonal therapy (p=0.043). On treatment received, a significant relationship was noted with sexual attractiveness (p=0.009), radiotherapy (p=0.029), hormonal therapy (p=0.038) and targeted therapy (p=0.047). Ethnicity and Marital status showed no significant relationship with all the specific learning needs. Findings of this study concluded that certain patient factors had significant relationship with certain specific learning needs. All the patient factors studied and their influence on the specific learning needs were taken into consideration prior to developing the breast cancer education package.

  18. Fulltext Dengue Infection Complicated by Hemophagocytic Lymphohistiocytosis: Experiences From 180 Patients With Severe Dengue
    Kan FK, Tan CC, Von Bahr Greenwood T, Khalid KE, Supramaniam P, Hed Myrberg I, et al.
    Clin Infect Dis, 2020 05 23;70(11):2247-2255.
    PMID: 31188423 DOI: 10.1093/cid/ciz499
    BACKGROUND: Globally, ~500 000 people with severe dengue (SD) require hospitalization yearly; ~12 500 (2.5%) die. Secondary hemophagocytic lymphohistiocytosis (sHLH) is a potentially fatal hyperinflammatory condition for which HLH-directed therapy (as etoposide and dexamethasone) can be life-saving. Prompted by the high mortality in SD and the increasing awareness that patients with SD may develop sHLH, our objectives were to (1) determine the frequency of dengue-HLH in SD, (2) describe clinical features of dengue-HLH, (3) assess mortality rate in SD and dengue-HLH, and (4) identify mortality-associated risk factors in SD.

    METHODS: A 5-year retrospective single-center study in all adult patients with SD admitted to a tertiary intensive care unit in Malaysia.

    RESULTS: Thirty-nine of 180 (22%) patients with SD died. Twenty-one of 180 (12%) had HLH defined as an HLH probability ≥70% according to histo score (HScore); 9 (43%) died. Similarly, 12 of 31 (39%) fulfilling ≥4 and 7 of 9 (78%) fulfilling ≥5 HLH-2004 diagnostic criteria died. Peak values of aspartate aminotransferase (AST), alanine aminotransferase, lactate dehydrogenase, and creatinine correlated to fatality (odds ratios [ORs], 2.9, 3.4, 5.8, and 31.9; all P < .0001), as did peak ferritin (OR, 2.5; P = .0028), nadir platelets (OR, 1.9; P = .00068), hepatomegaly (OR, 2.9; P = .012), and increasing age (OR, 1.2; P = .0043). Multivariable logistic regression revealed peak AST (OR, 2.8; P = .0019), peak creatinine (OR, 7.3; P = .0065), and SOFA (Sequential Organ Failure Assessment) score (OR, 1.4; P = .0051) as independent risk factors of death.

    CONCLUSIONS: Be observant of dengue-HLH due to its high mortality. A prospective study is suggested on prompt HLH-directed therapy in SD patients with hyperinflammation and evolving multiorgan failure at risk of developing dengue-HLH.

  19. Drivers of food waste generation: Case study of island-based hotels in Langkawi, Malaysia
    Kasavan S, Mohamed AF, Abdul Halim S
    Waste Manag, 2019 May 15;91:72-79.
    PMID: 31203944 DOI: 10.1016/j.wasman.2019.04.055
    Food waste (FW) generation from hotel operations have a significant negative impact on the environment, society and economy. Hence, the urgent need to introduce sustainable food management to reduce both FW and operational costs in hotels. The aim of this paper is to identify the drivers of FW generation and barriers to sustainable food waste management (SFWM) in island based hotels. The data were collected using in-depth interview coupled with the observations conducted at 23 selected hoteliers in Langkawi Island, Malaysia. Based on the analysis, using qualitative content analysis (QCA), eight FW drivers were identified and the drivers were classified into three categories of factors, mainly internal, external and intermediate influence. There are four FW drivers identified as internal factors that influenced the implementation of food waste management namely (1) poor hotel management and policies, (2) lack of skills in food preparation, (3) lack of facilities and FW technology and (4) non-implementation of waste audit and waste separation. For external factors, there are two FW drivers, including (5) unsustainable food consumption patterns of the customers and (6) risk of food ingredients spoilage. As for intermediate factors, two FW drivers were identified, which are (7) ineffective communication and (8) inadequate education and awareness. Findings from this study contribute towards a better understanding on the complexity of FW issues, particularly for island-based hotel sector. It was also suggested that a holistic approach with multi-stakeholders is crucial to reduce food wastage towards achieving SFWM.

  20. The Patient's Charter - Validating actual services provided to the outpatient
    Khoo CM, Lim YL, Abdul H, Zaharudin R, Sharipah A, Azirawati J, et al.
    JUMMEC, 1997;2:107-110.
    The Patient's Charter tells about the rights and standard of service a patient can expect. However, little information is available to gauge the reality of the charter in real practice. This survey was performed to determine the validity of the charter to the services provided and to identify areas of improvement if the charter is to be revised. A questionnaire-based survey was used to seek information from 196 patients who attended the Outpatient Department in Banting District Hospital over a period of four days. The overall waiting time for registration, to be seen by a doctor and for medication were 17.4 ± 2.0 minutes, 25.3 ± 2.6 minutes and 15.8 ± 1.3 minutes respectively. The overall waiting time for the whole consultation was 61.4 ± 4.9 minutes. Only 30.8% respondents knew about the Patient's Charter. The Patient's Charter appears to be valid for the actual services provided. There have to be measures to increase the awareness of the charter to the public perhaps via pamphlets and to provide a multi-linguistic charter.
