Adequate nutrition is important for mothers and their offspring during and after birth. This cross sectional study was conducted to determine nutritional status and nutritional knowledge of pregnant women from two selected private hospitals in Klang Valley, Malaysia. A total of 236 Malay pregnant women aged between 20 to 45 years old (mean age 31+5 years) were recruited through convenient sampling method. Socio-demographic data, nutritional knowledge and a 24-hours diet recall were obtained through a self-administered questionnaire. Anthropometric and haemoglobin data were obtained from the antenatal records in the respective hospitals. The percentages of participants who were underweight, normal, overweight and obese before pregnancy were 12.7%, 55.1%, 25.0% and 7.2% respectively. Among those who were obese before pregnancy, a total of 59.7% had inadequate weight gain, 24.6% gained adequate weight and 15.7% gained excessive gestational weight. About 33.5% of subjects were anaemic (Hb < 11.0g/dL). The mean daily energy intake of the participants was 1748 ± 526 kcal which was 76% of RNI. Calcium (73% of RNI), folic acid (36% of RNI), niacin (89% of RNI) and vitamin D (40% of RNI). The nutritional knowledge level of subjects was moderate (51.9 ± 13.8%). Lower monthly household income (p < 0.001), educational level (p < 0.001) and gestational stage (p < 0.05) of participants were associated with a lower nutritional knowledge level. Nutritional knowledge score was positively correlated with gestational weight gain (r = 0.166, p < 0.05) and haemoglobin level (r = 0.200, p < 0.05). Subjects who claimed practising food taboos had higher nutritional knowledge score (54.9 ± 12.5%) than those who did not (49.9 ± 14.4%)(p < 0.05). A comprehensive nutrition education should be integrated in the antenatal classes to improve nutritional status of pregnant women.
This study was conducted to determine types of educational needs among stroke patients admitted to Hospital Universiti Sains Malaysia. Stroke patients (n = 41) were conveniently recruited from Medical and Surgical Ward between September to December 2012. Data were obtained using semi-guided administered questionnaires and from the medical reports. Patients were given adequate time to complete the lifestyle history and educational needs on stroke with researcher’s assistance. Instrument on the educational needs consisted of five themes including general information on stroke, management of risk factors, treatments of stroke, rehabilitation and post-stroke problems and post-stroke diet management. Findings indicated majority of the stroke patients were female (58.5%), between 56 to 65 years old (39.0%) and diagnosed with ischemic stroke (68.3%). Patients had history of hypertension (85.4%), diabetes (46.3%), hyperlipidemia (29.3%), ischemic heart disease (22.0%) and atrial fibrillation (2.4%). Eleven of them (26.9%) were ex-smokers and many practice unhealthy lifestyle such as lack of exercise (80.5%) and prefer fried foods (68.3%). Most patients were on multiple pharmacotherapies (92.7%) to treat their medical conditions. Educational needs rated highest need to know among stroke patients were on prevention (92.7%), fi rst aid management (85.4%), complications (85.4%) and recurrence (85.4%) of stroke in general. Other concerned were about possibility of cure with drug (92.7%), range of motion exercise (82.9%), fi sh intake (78.0%), fruit and vegetable consumption (78.0%) after stroke. Findings from this study provide a baseline information on types of educational needs among stroke patients. More patient educational intervention on primary and secondary stroke prevention should be structured in hospital and community settings in the future.

Literature review suggests that polyphenols in particular flavonoids, are beneficial for mental health during aging process. This review examines the effect of consumption of all polyphenols groups on mental health and cognitive status during aging process. The keywords searched were “mental health,” “depression,” “anxiety,” “stress” and “cognitive” combined with “dietary,” and “polyphenols.” The databases including PubMed, Web of Science and CAB Abstracts were searched for a period of 10 years. A total of 11 studies were identifi ed to fulfi ll the inclusion criteria. From this review, polyphenols may confer beneficial effects towards mental health, in particular the decline in cognitive functions during aging process, however, some studies showed contradictory results. Polyphenols have been proven to improve language and verbal ability, which is among the main vulnerable aspects in cognitive decline in pathological brain aging. In contrast, polyphenols intake did not seem to affect executive functioning. The effects of polyphenols towards cognitive status were more prominent among the elderly as compared to young and middle-aged adults. This review also shows that flavonoids is the main type of polyphenols that confer positive effects towards cognitive status during aging. This review provides evidence that consumption of polyphenols may lead to cognitive and mental health benefits. Further clinical trials involving human subjects are required with carefully designed methodology to elucidate the potential mechanisms underlying the relationship between polyphenols consumption and improvement in cognitive and mental health status.
Kajian pengimejan resonans magnet kefungsian (fMRI) subjek tunggal ini menyelidiki kesan daya dan laju tepikan ke atas sifat pengaktifan korteks berkaitan motor semasa tepikan jari rentak sendiri secara bilateral. Subjek melakukan empat cara tepikan jari rentak sendiri iaitu sentuh-perlahan (SP), sentuh-laju (SL), tekan-perlahan (TP) dan tekan-laju (TL) dalam satu imbasan fMRI. Model linear am (GLM) digunakan dalam penjanaan pengaktifan otak. Pentaakulan statistik kemudiannya dibuat mengenai pengaktifan otak menggunakan teori medan rawak (RFT) Gaussian pada aras keertian diperbetulkan (α = 0.05), dengan andaian tiada pengaktifan berlaku. Keputusan mendapati otak mengkoordinasi tepikan jari bilateral rentak sendiri dengan penglibatan korteks berkaitan motor iaitu girus presentral (PCG) bilateral, serebelum bilateral dan juga kawasan motor tambahan (SMA). Peningkatan daya tepikan menonjolkan pengaktifan yang bererti (p < 0.05 diperbetulkan) pada PCG bilateral (Kawasan Brodmann (BA) 6) sejajar dengan fungsinya dalam mencetus tindakan motor seperti mengawal daya tepikan. Peningkatan laju tepikan pula menyebabkan peningkatan pengaktifan otak secara bererti (p < 0.05 diperbetulkan) hanya pada korteks kesatuan somatoderia iaitu pada lobus parietal superior (SPL) kanan atau BA7 kanan. Ini mencadangkan bahawa SPL memainkan peranan penting dalam mengkoordinasi pergerakan berkemahiran terancang.
Patients who lost their eyes as results of accidents or diseases (e.g. retinoblastoma) usually underwent enucleation or evisceration. They were then fi tted with ocular prosthesis to prevent collapse of the globe and also for cosmetic effects. Custom made ocular prosthesis is almost unheard of in this country for most hospitals supply ready-made (stock) prosthesis. The cosmetic results of stock prosthesis are often unsatisfactory. Besides being uncomfortable, stock prosthesis may also induce allergic reaction that may lead to papillary conjunctivitis. The Optometry Clinic at UKM started its custom made prosthetic service in 2010. We described here two cases of patients who complained of discomfort with their old stock prosthesis and re-fitted with custom made prosthesis. We also highlight the importance of proper hygiene and maintenance so that ocular prosthesis can be used for as long as possible. This article aims to create awareness among eye care practitioners and showcase the cosmetic benefi ts of custom made ocular prosthesis.

Urografi intravena (IVU) dan tomografi berkomputer helikal tanpa kontras (UHCT) urografi adalah dua prosedur utama yang akan dijalankan semasa penyiasatan radiologi bagi pengesanan urolitiasis (batu karang) pada sistem genitourinari. Dedahan terhadap sinaran radiasi merupakan faktor kebimbangan utama dalam kedua-dua prosedur. Oleh itu, satu kajian perbandingan dos sinaran telah dijalankan antara prosedur IVU dan UHCT urografi di samping menentukan faktor dedahan optimum bagi kedua-dua prosedur tersebut. Kajian ini telah dijalankan ke atas fantom antropomorfik seluruh tubuh mengikut protokol sebenar bagi prosedur UHCT urografi dan penghasilan radiografi bersiri berserta dengan pemberian media berkontras bagi prosedur IVU. Sebanyak tiga parameter dedahan voltan tiub digunakan iaitu 75 kVp, 80 kVp dan 85 kVp bagi prosedur IVU dan 100 kVp, 120 kVp dan 140 kVp bagi prosedur UHCT urografi . Hasil dos sinaran bagi prosedur IVU yang diperolehi adalah 1.40 mSv, 2.10 mSv dan 2.79 mSv bagi 75 kVp, 80 kVp dan 85 kVp. Manakala bagi prosedur UHCT urografi , sebanyak 0.76 mSv, 1.32 mSv dan 1.82 mSv dos sinaran direkodkan bagi 100 kVp, 120 kVp dan 140 kVp. Hasil kualiti imej optimum adalah menggunakan dedahan sebanyak 85 kVp bagi prosedur IVU dan 120 kVp bagi prosedur UHCT urografi . Kesimpulannya, walaupun tidak terdapat perbezaan signifi kan, dos sinaran yang terhasil daripada prosedur IVU adalah kekal lebih tinggi daripada prosedur UHCT urografi .
Kromium merupakan mineral yang penting dan kofaktor insulin yang memainkan peranan penting sebagai hormon yang membantu dalam regulasi gula dalam darah. Penduduk Kelantan sering dikaitkan dengan pengambilan makanan berasaskan gula. Petani merupakan golongan yang berisiko tinggi kerana pendedahan terhadap pestisid dan pengambilan makanan bergula boleh mempengaruhi paras kromium. Objektif kajian ini adalah untuk mengetahui status paras kromium dalam kalangan petani yang terdedah kepada pestisid dan baja kimia di Kelantan. Kajian ini adalah kajian keratan rentas yang dilakukan di Bachok dan Pasir Puteh, Kelantan. Responden adalah seramai 113 petani yang terdedah kepada pestisid atau baja kimia tidak kurang daripada satu tahun. Subjek ditemu bual menggunakan soal selidik pengetahuan, sikap dan amalan (KAP) yang telah divalidasi untuk informasi berkaitan data demografi k. Sampel kuku dan rambut telah dianalisia dengan menggunakan kaedah pencernaan asid dan Inductively Coupled Plasma Mass Spectroscopy (ICPMS) untuk mendapatkan paras kromium. Hasil kajian menunjukkan 81.4% adalah petani lelaki dan 18.6% adalah perempuan. Paras kromium kuku (125.82 ± 47.81 μg/L) dan rambut (39.63 ± 5.70 μg/L) petani adalah lebih rendah berbanding julat piawai kuku (6200 μg/L) dan rambut (100-2500 μg/L). Tiada perbezaan paras kromium yang signifi kan (p > 0.05) menurut jantina, umur, glukosa darah, tempoh pendedahan pestisid dan pemakanan. Petani yang merokok menunjukkan paras kromium yang lebih rendah (p < 0.05) berbanding petani yang tidak merokok. Kesimpulannya, paras unsur kromium petani di Bachok dan Pasir Puteh adalah rendah berbanding julat normal dan petani harus berhenti merokok kerana merokok akan merendahkan paras kromium.
Media pendidikan bercetak merupakan saluran komunikasi yang utama dalam pendidikan kesihatan awam. Namun, kajian tempatan yang menilai penerimaan media pendidikan bercetak masih terhad di Malaysia. Maka, kajian ini dilakukan untuk menilai media pendidikan bercetak sedia ada yang mensasarkan obesiti di kalangan kanak-kanak untuk kegunaan dalam program pendidikan atau promosi pemakanan. Kajian ini melibatkan dua peringkat. Peringkat pertama merupakan tinjauan keperluan iaitu tinjauan terhadap media pendidikan bercetak sedia ada yang mensasarkan kanak kanak yang mengalami masalah berlebihan berat badan dan obes dan kajian rintis terhadap borang soal selidik yang dibentuk. Manakala peringkat kedua adalah penilaian penerimaan subjek kajian terhadap media pendidikan bercetak dan perubahan tahap pengetahuan mereka selepas membaca media pendidikan bercetak yang diberikan. Skala Likertn digunakan dalam penilaian ini iaitu daripada 1 (sangat tidak memuaskan) hingga 5 (sangat memuaskan). Jumlah subjek dalam kajian ini adalah seramai 67 orang yang terdiri daripada golongan profesional dalam bidang pendidikan dan kesihatan (n = 7), subjek dewasa (n = 30) dan subjek kanak-kanak (n = 30). Di dalam kajian ini, subjek dewasa diberi satu buku kecil yang mengandungi maklumat berkenaan pencegahan dan pengurusan masalah obesiti di kalangan kanak-kanak seperti komplikasi masalah obesiti dan penyediaan makanan. Subjek kanak-kanak pula menerima satu buku kecil yang mengandungi maklumat berkenaan piramid makanan, kepentingan sarapan, aktiviti fi zikal dan sebagainya di samping satu poster yang mengandungi maklumat berkenaan pemilihan makanan sihat. Manakala golongan profesional menerima semua media pendidikan bercetak ini. Kajian ini mendapati penerimaan subjek terhadap isi kandungan, gambar, jadual dan rajah, warna, susun atur gambar, susun atur kandungan, bahasa dan saiz huruf bagi ketiga-tiga media pendidikan bercetak adalah pelbagai, iaitu daripada sangat tidak memuaskan hingga sangat memuaskan. Min skor penilaian keseluruhan terhadap buku kecil yang mensasarkan populasi dewasa adalah 3.9 ± 0.5 manakala min skor penilaian keseluruhan terhadap buku kecil yang mensasarkan populasi kanak-kanak adalah 4.3 ± 0.4 dan poster adalah 3.9 ± 0.9. Skor pengetahuan pemakanan golongan profesional meningkat dari 88.6 ± 11.2% kepada 95.5 ± 3.2% selepas membaca media tersebut. Skor pengetahuan pemakanan subjek dewasa juga meningkat secara signifi kan (p < 0.001)daripada 67.7 ± 13.6% kepada 84.8 ± 15.9%; bagi subjek kanak-kanak, skor pengetahuan pemakanan juga meningkat secara signifi kan (p < 0.001) daripada 65.3 ± 14.4% kepada 84.0 ± 11.4%. Kesimpulannya, media pendidikan bercetak sedia ada mendapat penerimaan yang baik dan dapat meningkatkan tahap pengetahuan kumpulan sasaran. Oleh itu, media pendidikan bercetak tersebut sesuai digunakan dalam mana-mana program pendidikan pemakanan yang berkaitan dengan obesiti kanak-kanak.
Penanda kadar pusing ganti tulang (PPT) adalah berguna dalam penilaian status kesihatan tulang. Namun, pengaruh umur, kumpulan etnik dan antropometri badan terhadap aras PPT dalam kalangan lelaki masih belum jelas. Kajian ini bertujuan untuk menentukan pengaruh faktor-faktor tersebut terhadap aras PPT, iaitu aras osteokalsin (OC) dan telopeptida terminal-C kolagen jenis 1 (CTX-1) dalam kalangan lelaki Cina dan Melayu berumur 20 tahun dan ke atas (N = 407) di Lembah Klang. Subjek dikumpulkan melalui kaedah persampelan bertujuan. Ketinggian, berat badan dan indeks jisim badan subjek telah diukur. Darah mereka diambil pada waktu pagi untuk analisis aras OC dan CTX-1 serum dengan asai imunoserap terangkai enzim. Hasil kajian menunjukkan aras OC dan CTX-1 adalah lebih tinggi secara signifi kan dalam kalangan lelaki Melayu berbanding dengan lelaki Cina (p < 0.05). Aras OC dan CTX-1 adalah paling tinggi dalam kalangan lelaki berumur 20-29 tahun, dan kemudiannya menurun secara signifi kan berbanding dengan dekad sebelumnya dalam kalangan lelaki berumur 30-39 tahun (p < 0.005). Perbezaan aras kedua-dua PPT ini adalah tidak signifi kan di antara lelaki berusia 30-39 tahun dengan lelaki yang lebih tua (> 40 tahun dan ke atas) (p > 0.005). Aras OC berkorelasi secara signifi kan dan negatif dengan berat dan indeks jisim tubuh subjek dan korelasi ini adalah signifi kan untuk lelaki 20-39 tahun sahaja (p < 0.05). Aras CTX-1 tidak berkorelasi dengan antropometri badan subjek (p > 0.05). Secara kesimpulannya, aras PPT dalam kalangan lelaki di Malaysia boleh dipengaruhi oleh faktor umur, kumpulan etnik dan antropometri badan. Faktor-faktor ini seharusnya diambil kira dalam penilaian status kesihatan tulang lelaki berdasarkan aras PPT.
Polyphenol is a non-nutrient phytochemical compound existed abundantly in plant-based diet which has the properties to prevent age related oxidative damage induced diseases. However, there are difficulties in quantifying its intake and local food frequency questionnaire (FFQ) for the assessment is not available. Therefore, this study aimed to develop and validate FFQ for estimation of dietary polyphenol intake among 93 individuals aged 60 years and above recruited from several senior citizen clubs in Klang Valley. Phase I of the study involved the development of FFQ consisted of 117 items under 9 categories and formation of the database extracted from PHENOL-EXPLORER. In Phase II, the intake of polyphenol estimated using FFQ was compared with reference method consisted of 2-day diet records and diet history questionnaire (DHQ). The mean dietary polyphenol intake estimated from FFQ and the reference method was 2770.7 ± 1552.4 mg/d and 2171.4 ± 898.8 mg/d, respectively. Spearman’s rho and Kendall’s tau-b analysis indicated that there was a significant positive correlation between polyphenol intake estimated from FFQ and reference method (r = 0.41, p < 0.001; r = 0.28, p < 0.001). For Bland-Altman plot, 95.7% of scattered plot fell within ± 1.96 SD limits of agreement revealed that there was good agreement between the two methods used. Cross-classifi cation analysis showed that 36.6% was categorized in the same quartile, 78.5% in identical and contiguous quartiles, with only 3.2% in the opposite quartiles. Regression analysis showed that all categories in FFQ signifi cantly account for the inter-variance for dietary polyphenol intake after controlling for the other variables (R2 = 1.000, p < 0.001). In conclusion, the newly developed FFQ is considered valid and has the potential to be used as a tool to estimate polyphenol intake among elderly individuals in Malaysia.
There has been a significant increase in research on probiotics-associated health benefits in the last 20 years. Many studies carried out in vitro and clinically show that consumption of probiotics inhibits the growth of pathogenic microorganisms. Furthermore, the consumption of probiotics also enhances the host immune response and decreases the levels of carcinogenesis-inducing enzymes. These positive outcomes have led to the use of probiotics in prevention and treatment of infectious diseases like bacterial or antibiotic associated diarrhea, chronic inflammatory bowel diseases and colon cancer. This review summarises literature pertaining to mechanistic actions of probiotics in improving the well-being of hosts.
Kualiti merupakan elemen terpenting dalam proses pengeluaran atau perkhidmatan yang dihasilkan oleh sesebuah organisasi kepada pelanggan.

Kajian ini bertujuan untuk mengenal pasti kualiti perkhidmatan kesihatan awam yang dapat diakses oleh buruh asing. Pengukuran kualiti perkhidmatan kesihatan dalam kajian ini dapat dibahagikan kepada tiga aspek iaitu keadaan perkhidmatan kesihatan, tempoh masa menunggu dan layanan kakitangan hospital terhadap buruh asing. Dapatan kajian menunjukkan sebilangan besar buruh asing berpuas hati dengan kualiti perkhidmatan kesihatan yang diterima oleh mereka.
Pelbagai usaha dan kempen telah dijalankan oleh kerajaan untuk meningkatkan penerimaan orang ramai terhadap pengambilan ikan air tawar sebagai menu harian. Objektif kajian ini adalah untuk menilai penerimaan terhadap sajian ikan air tawar serta menentukan faktor-faktor yang mempengaruhi pengambilannya dalam kalangan pelajar Universiti Kebangsaan Malaysia (UKM). Seramai 232 pelajar dipilih secara rawak daripada pelbagai fakulti di UKM (kampus Bangi). Di samping pelajar, pengendali makanan di kafeteria UKM turut terlibat dalam kajian ini. Soal selidik digunakan bagi menentukan tahap kefahaman dan penerimaan pelajar terhadap ikan air tawar, kekerapan pengambilan sajian ikan air tawar serta faktor-faktor yang mempengaruhi pengambilannya. Kebolehdapatan dan kepelbagaian menu sajian ikan air tawar dikenal pasti melalui tinjauan di kafeteria UKM terpilih. Majoriti responden (95.7%) mengetahui ikan air tawar secara umum tetapi hanya 55.6% responden yang mengetahui jenis atau spesies ikan air tawar. Kebanyakan responden (63.3%) memilih ikan air tawar sebagai sajian. Ujian Khi Kuasa Dua menunjukkan terdapat perkaitan yang signifikan antara agama dan bangsa dengan pemilihan ikan air tawar sebagai sajian (p < 0.05). Ikan Keli merupakan ikan yang paling digemari oleh sejumlah 51.9% responden. Sajian yang paling digemari oleh majoriti responden (36.2%) ialah sajian ikan goreng. Bagi kebanyakan responden (43.2%), sajian ikan air tawar diambil atas faktor rasanya yang sedap. Kebanyakan kafeteria di UKM yang dikaji menjual sajian ikan air tawar dan hal ini didorong terutamanya oleh faktor mempelbagaikan menu di kafeteria mereka. Sejumlah 69.2% kafeteria melaporkan bahawa pelajar dapat menerima dengan baik sajian ikan air tawar yang disediakan tetapi hanya bagi jenis sajian ikan air tawar terpilih. Hasil kajian ini dapat memberi maklumat kepada kerajaan berkenaan penerimaan dan kesedaran pelajar universiti terhadapikan air tawar serta membantu pihak-pihak tertentu khususnya pengendali makanan di kafeteria UKM dalam menyediakan sajian ikan air tawar yang bersesuaian dengan kegemaran pelajar.
Antineutrophil cytoplasmic antibodies (ANCA) are autoantibodies directed against primary granules of neutrophils and monocytes' lysosomes. In general, c-ANCA is strongly associated with vasculitic disorders mainly in ANCA-associated systemic vasculitis (AASV). p-ANCA have been identified in several diseases such as primary (AASV) and secondary vasculitis such as collagen vascular diseases, rheumatoid arthritis and inflammatory bowel diseases given the term 'ANCA-associated disease.' The objective of this study was to determine the rate of ANCA positivity by indirect immunofluorescent (IF) and enzyme linked immunosorbent assay (ELISA) and its association with AASV and ANCA associated diseases. Serum from patients with history suspicion of systemic vasculitis were tested for ANCA by IF. Those samples positive for ANCA by IF were further tested for antibodies against myeloperoxidase (MPO) and proteinase 3 (PR3) using the ELISA. Clinical data from medical records were obtained and analyzed. Of 468 samples, a total of 110 were positive for ANCA by IF. IF results showed a p-ANCA pattern in 96 patients and c-ANCA in 14. Of 110 IF positive ANCA, 45 patients were positive by ELISA. Seventeen were positive for MPO-ANCA, 9 were PR3-ANCA positive and 19 were both MPO and PR3 positive. Only 2 patients were classified AASV ie Wegener granulomatosis and the other with microscopic polyangiitis. The remaining patients (n = 108) may be classified as ANCA associated diseases. Our study showed that pANCA (87.3%) was the more common ANCA pattern and 40.9% of IF positive samples were positive for PR3- and MPOANCA.
This study investigated the functional specialisation characteristics of brain in multiple right-hand dominant subjects pertaining to the activation of the cerebral motor cortices evoked by unilateral finger tapping, especially in primary motor (M1) and supplementary motor (SMA) areas. This multiple-subject study used unilateral (UNIright and UNIleft) selfpaced tapping of hand fingers to activate the M1 and SMA. Brain activation characteristics were analysed using statistical parametric mapping (SPM). Activation for UNIright and UNIleft showed the involvement of contralateral and ipsilateral M1 and SMA. A larger activation area but with a lower percentage of signal change (PSC) were observed in the left M1 due to the control on UNIright (4164 voxels at a = 0.001, PSC = 1.650) as compared to the right M1 due to the control on UNIleft (2012 voxels at a = 0.001, PSC = 2.377). This is due to the influence of the tapping rate effects which is greater than what could be produced by the average effects of the dominant and sub-dominant hands. The significantly higher PSC value observed in the right M1 (p < 0.05) is due to a higher control demand used by the brain in coordinating the tapping of the sub-dominant fingers. The findings obtained from this study showed strong evidence of the existence of brain functional specialisation and could be used as baseline references in determining the most probable motor pathways in a sample of subjects.
A cross-sectional study was conducted among 200 Malays in Kuala Pilah, Tampin, Bahau, Gemencheh and Seremban towards food allergy in Negeri Sembilan. Questionnaire were used to determine demographic data, allergy symptom, practice and knowledge of respondents towards food allergy. Majority of the respondents that have food allergy were children 44% and shrimp was the most common allergen among children (25%). Family history is found to be associated with the age group and place of residents (p < 0.05). Common symptom that manisfested by respondents includes rashes (35%). Furthermore, the study showed that the respondents were concerned about their food allergy and 96% of the respondents reduced the intake of food that caused allergy. The level of knowledge related to food allergy was found to be associated with age group (p < 0.05). In conclusion, the study found that shrimp is the most common food allergy for all age group. Response towards food allergy is that they reduce the intake of food that cause allergy and the knowledge
towards food allergy is associated with age group. Therefore, early screening should be conducted to identify types of alergy so that appropriate treatment can be given to the patients. Health education on allergy is also important to improve knowledge and patients’ compliance towards treatment.

Bunga rafflesia cantleyi Solms-Laubach merupakan salah satu jenis tumbuhan liar boleh ditemui di hutan tanah rendah di Semenanjung Malaysia dan digunakan secara meluas dalam ubatan tradisional. Objektif utama dalam kajian ini adalah untuk menguji keberkesanan ekstrak tumbuhan ini sebagai agen aktiviti antibakteria. rafflesia cantleyi Solms-Laubach diesktrak dengan menggunakan tiga kaedah pengekstrakkan berperingkat iaitu petroleum eter (PE) diikuti dengan etil asetat (EA) dan berakhir dengan etanol. Kesemua ekstrak ini kemudiannya diuji terhadap beberapa bakteria ujian iaitu Staphylococcus aureus ATCC 25923, Staphylococcus epidermidis, Escherichia coli ATCC 25922 dan Salmonella typhimurium dengan menggunakan kaedah resapan telaga. Hasil keputusan menunjukkan ekstrak etil asetat dan etanol mempunyai kesan perencatan bakteria yang baik, manakala ekstrak petroleum eter langsung tidak menunjukkan sebarang aktiviti antibakteria. Hasil kajian juga mendapati bahawa ekstrak etil asetat lebih ketara merencat kesemua bakteria yang diuji berbanding dengan ekstrak ethanol. Dua ujian lain yang dijalankan iaitu ujian penentuan nilai kepekatan perencatan minimum (MIC) dan nilai kepekatan minimum bakterisidal (MBC) didapati menyokong keputusan ujian kaedah resapan telaga di mana nilai MIC yang diperoleh bagi ekstrak etil asetat adalah lebih rendah iaitu dalam julat 6.25 hingga 12.5 mg/ml dan nilai MBC pula dalam julat 25.0 hingga 50.0 mg/ml berbanding ekstrak etanol dengan nilai MIC yang lebih besar iaitu dalam julat 25.0 hingga 50.0 mg/ml dan nilai MBCnya adalah 100.0 mg/ml.
Acanthamoeba is a free living protozoa that can cause keratitis and granulomatous amoebic encephalitis. Physiological characteristics of this amoeba are found to have a medical importance in which it can be related to the pathogenicity potential of the organism. This study was carried out to investigate the physiological characteristics of survivability during axenization. Six Acanthamoeba strains from three clinical isolates (HSB 1, HKL 48 and HKL 95) and three environmental isolates (PHS 2, PHS 11 and PHS 15) were used in this study. Axenization test was done by treating cysts with hydrochloric acid (3%) and Page saline containing Gentamicin (100 µg/ml). Cysts were then cultured into PYG enrich media, incubated at 30oC and the presence and proliferation of trophozoites of Acanthamoeba were observed. This study showed that PHS 15, HSB 1, HKL 48 and HKL 95 could be axenized but they have poor proliferation rate in PYG enrich media. The result showed that the difference between both clinical and environmental isolates was observed in two strains; PHS 2 and PHS 11. This indicates that there is a possibility that the physiological traits of strains from both isolates are the same and strains from the environment are able to show the pathogenic potential and capable of causing infection to human.
The present study was carried out to determine the concentrations of selected metal elements (lead, copper, manganese, zinc and iron) in 51 samples of commercial drinking water and tap water available in Malaysia. The results indicated that low metal elements were found in the studied water samples. Lead, manganese, zinc and iron were not detected in some of the studied samples, except copper. The concentrations of the metal elements in the studied samples were well below the maximum permitted concentrations as recommended. Therefore these drinking water are safe for consumption and do not pose adverse effect to the health of consumers due to metal toxicity.
This survey was carried out to examine the habits of practising optometrists in private practice around Kuala Lumpur and the Klang Valley. A questionnaire survey was prepared that encompassed questions on ophthalmic intruments and appliances, services offered, eye examinatians carried aut and patient management, failure ta carry out comprehensive eye examination, community engagements and their opinion on optometrists as primary eyecare practitioners. The questionnaire was sent to 100 registered optometrists practising in Kuala Lumpur and the Klang Valley. About 64 optometrists responded and returned the questionnaire, but 3 of them were excluded because they were incomplete. The results showed almast all aptornetric practice has all the equipment related to optometry practice except for tonometer and visual field measurement. F orty~four percent ( 44%) of aptometrists undertook comprehensive eye examinatians and necessary referred patients far further examinations. Optometrists who did not perform comprehensive eye examinations give reasons of inadequate equipment and clients who want a quick examination. ln conclusion optometric practice provide almost all the equipments required for optometrists to practice as primary health care practioners but only 44% of optometrists carriedout comprehensive eye examinations. Optometrists in private practice need to practice all the skills they learned and play important roles in educating the public in an effort to improve the primary eyecare of society.
