Fulltext Absence of Apo B R3500Q Mutation among Kelantanese Malays with Hyperlipidaemia

Kyi WM, Isa MN, Rashid FA, Osman JM, Mansur MA

Malays J Med Sci, 2000 Jan;7(1):16-21.

Familial defective apolipoprotein B-100 (FDB) is an autosomal dominant genetic disorder associated with hypercholesterolaemia and premature coronary heart disease. FDB is caused by mutations in and around the codon 3500 of the apolipoprotein B (apo B) gene. Apo B R3500Q mutation is the first apo B mutation known to be associated with FDB and it is the most frequently reported apo B mutation in several different populations. The objective of the present study was to determine the association of apo B R3500Q mutation with elevated plasma cholesterol concentration in Kelantanese population in which both hypercholesterolaemia and coronary heart disease are common. Sixty-two Malay subjects with hyperlipidaemia, attending the lipid clinic at Hospital Universiti Sains Malaysia, Kelantan, were selected for this study. The DNA samples were analysed for the presence of apo B R3500Q mutation by polymerase chain reaction-based restriction fragment analysis method using mutagenic primers. This mutation was not detected in the subjects selected for this study. Apo B R3500Q mutation does not appear to be a common cause of hypercholesterolaemia in Kelantanese Malays.

In direct age-adjustment, a common age-structured population is used as standard. This population may actually exist (e.g., United States population, 1999) or may be fictitious (e.g., two populations may be combined to create a standard). In indirect age-adjustment, a common set of age-specific rates is applied to the populations whose rates are to be standardized. The simplest and most useful form of indirect adjustment is the standardized mortality ratio (SMR) (5).

Fulltext The pilot study of whoqol-100 (malay version)

Hasanah CI, Razali MS

Malays J Med Sci, 1999 Jul;6(2):21-5.

PMID: 22589685 MyJurnal

In confronting the advances in the new treatment for incurable illnesses there is an increasing need for doctors to be aware of their patients' cognition and feeling related to their quality of life (QOL). Recognizing this need the authors translated and pilot tested the WHOQOL-100, a genuinely international measure of QOL by the World Health Organization (quality of life group). The WHOQOL-100 Malay version was pilot tested on 50 healthy controls and 250 ill subjects, suffering from hypertension, diabetes mellitus, those suffering from both hypertension and ischaemic heart disease, epilepsy and schizophrenia. The results showed several unique features of the QOL, which were influenced by different types of illnesses. The information obtained is different and probably not observable from clinical consultations. This study will be an impetus for further studies using the WHOQOL-100 assessment tool in the local population.

Fulltext The use of electronic sensor in hormone analysis

Muda NE, Abu Bakar MA, Majlis BY

PMID: 22589683 MyJurnal

The development of antibody-based biosensor has grown steadily during recent years, and their use as a routine instrument in clinical application is not far from reality. This study has demonstrated the capability of conductometric sensor to quantitate human Follicle Stimulating Hormone (hFSH) from urine samples. The principles are adopted from Enzyme Linked Immunosorbent Assay (ELISA) technique. Self fabricated gold coated electrode was dipped in the microtiter well containing antibody-antigen complex. Substrate was added to the system to initiate a secondary reaction, which produced electroactive species and change the conductivity of the solution. The changes were proportional with the concentration of the hormone present. The results obtained correlate well with the conventional ELISA technique. Inter and intra assay variation (%CV) were under 6% and the lowest detection limit is 0.75 mIU/ml which was well under the physiological range of the hormone. This system offered advantages such as simplicity, reliability, minimal addition of reagents, freedom from turbidity and color problem, probability of miniaturizing the electrode thus minimizing the sample volume and the ability of on line data analysis. This study proved that Antigen-Antibody reaction via EIA could be detected electronically and it has a potential to be used as one of the measuring mode in clinical analysis.

Cystic Meningioma Masquerading as a Metastatic Tumor: A Case Report

Ramanathan N, Kamaruddin KA, Othman A, Mustafa F, Awang MS

Malays J Med Sci, 2016 May;23(3):92-4.

PMID: 27418876 MyJurnal

Cystic meningioma is a rare form of intracranial meningioma. Meningiomas are typically solid tumors but may rarely have cystic components. The diagnosis of cystic meningioma is clinically challenging as the finding of multiple intra-axial tumors, including metastatic tumors, is relatively common. We report a case of cystic meningioma initially diagnosed as a metastatic tumor from a recurrence of acute lymphoid leukemia. However, postoperative histopathological examination demonstrated an atypical meningioma.

Fulltext Glycaemic control of type 2 diabetic patients on follow up at Hospital Universiti Sains Malaysia

Eid M, Mafauzy M, Faridah A

Malays J Med Sci, 2003 Jul;10(2):40-9.

PMID: 23386796 MyJurnal

Two hundred and eleven (211) patients with type 2 diabetes mellitus who were on treatment and monitored for complications at the Outpatient Diabetes Clinic in Hospital Universiti Sains Malaysia, Kubang Kerian between 2001 - 2002 were selected for the study. A structured questionnaire was administered to obtain their medical and family history. Physical examination was performed and fasting venous blood sample was collected for plasma glucose and A1C analysis. Of the total 211 patients, only 4 % were on diet treatment alone, 37 % of them were on mono therapy while 59 % were on combination of therapies. Fasting plasma glucose (FPG) > 7.2 mmol/L and glycated hemoglobin (A1C) levels ≥ 7 % were observed in 60 % and 73 % of type 2 diabetic patients, respectively. Glycated hemoglobin level of 28 % of the subjects were < 7 %; 36 % were between 7 - 9 % and 36 % were more than 9 %. The worst glycaemic control was observed in Malay patients. A1C of Malay and non-Malay subjects were 8.7 ± 2.3 % and 7.7 ± 1.7 %, respectively. Younger patients (age group < 50 years) had significantly higher mean A1C than elderly patients. Duration of diabetes had a clear influence on glycaemic level. Patients with recently diagnosed diabetes (duration of disease < 5 years) had the best glycaemic control. In this study a large proportion of the patients had poor glycaemic control. The variables with significant effects on glycaemic control were ethnicity, age and duration of diabetes mellitus. Better treatment strategies and methods should be used to improve diabetes control and to reduce long-term complications of diabetes.

Chen AH, Aziz A

Malays J Med Sci, 2003 Jan;10(1):90-4.

PMID: 23365507

The purpose of this study was to investigate the relationship between heterophoria and refractive error. Thirty-six subjects (11 myopes, 25 emmetropes) participated in this study. Heterophoria was measured with the Free-Space Phoria Card at five different viewing distances (25cm, 33cm, 50cm, 100cm and 300cm). Regardless of the types of heterophoria, the amount of heterophoria reduced towards orthophoric position with increasing viewing distance. Emmetropes and myopes did not show any significant difference in the degree of heterophoria at different viewing distances (F = 0.30, p>0.05) or in the type of heterophoria (χ(2) = 2, p>0.05).

PMID: 23365506 MyJurnal

From 1996 to 2001, 393 thyroidectomies were performed and 25 (6.4%) patients underwent reoperative thyroid surgery at Hospital Universiti Sains Malaysia. All reoperated patients had undergone one prior thyroid operation. All were females with an average age of 39.1 years (18-61 years). The most frequent indication for reoperation was cancer in resected specimen of an originally misdiagnosed carcinoma treated by partial thyroid resection. Final histological diagnosis of 25 reoperations showed thyroid carcinoma in 22 (88%) cases and multinodular goiter in 3 cases. The overall interval between the initial and the reoperative procedures ranged from 3 weeks to 15 years. There was no post-operative mortality after reoperation. Post-operative complications were discovered in 5 patients, as 3 (12%) of whom had transient hypocalcaemia, one (4%) had wound breakdown and one (4%) had permanent recurrent laryngeal nerve palsy. Reoperative thyroid surgery is an uncommon operation with high complication rate.

Abdullah J, Abdullah MR

Malays J Med Sci, 2003 Jan;10(1):74-7.

PMID: 23365504 MyJurnal

There is no report in the English literature on the criteria for neuroablation or neuroaugmentation for the treatment of Parkinson's disease in a developing country like Malaysia. A prospective study of patients with Parkinson's disease from the north-eastern peninsular Malaysia was done to assess their suitability of surgery. Age, race, duration of illness and dementia were considered important factors towards the success of such surgical procedures. A mathematical model is suggested for future cases deemed to be suitable for neuroaugmentative or ablative surgery.

PMID: 23365502 MyJurnal

Tuberculosis is the top agenda among opportunistic diseases and the most leading cause of death in HIV/AIDS patients. A total of 406 AIDS patients were recruited in this retrospective and descriptive study. 123/406 (30.3%) were diagnosed as AIDS-related tuberculosis (TB). Their age range from 17 to 69 years with a mean (±SD) of 37.2 (±9.51. There were significant association between occupation, or mode of HIV transmission and tuberculosis infection (p< 0.05). Pulmonary tuberculosis 104/123 (84.6%) was the most common disease location among TB patients. We found the significant association between the clinical presentations i.e. fever, cough, sputum or hemoptysis and TB patients (p<0.05), moreover, the level of CD4 cell count plays a significant role in association with the disease (p<0.05) in this study.

Fulltext Test ordering pattern at the chemical pathology laboratory, hospital universiti sains malaysia

Al-Joudi FS, Wahab NA, Nordin H

Malays J Med Sci, 2003 Jan;10(1):46-51.

PMID: 23365500 MyJurnal

The utilization of the chemical laboratory resources at the Hospital Sains Malaysia was evaluated. More than 100,000 test requests received and performed over a 12-month period, were analyzed retrospectively. The analysis conducted included the abnormal results obtained, the degree of duplication of tests, and the extent of test-panel ordering. It was found that a relatively moderate degree of over-ordering was evident. The findings suggested that the main reasons for over-ordering were the use of panel tests of ordering, in addition to a small, yet significant degree of duplication. Strategies for cutting down the test ordering have been reviewed and discussed.

D'Souza UJ

Malays J Med Sci, 2003 Jan;10(1):43-5.

PMID: 23365499 MyJurnal

The antimetabolite, 5-fluorouracil is widely used in the treatment of cancers. Although its toxic effects on testis causing germinal epithelial sloughing, tubular atrophy and generation of multinucleated cells were reported, its effect on spermatogenesis has not been studied. Hence the present study was conducted to evaluate the effects of 5-fluorouracil on epididymal sperm count. Male Wistar rats were employed in the study (n=5 per group). The animals were injected (i.p) with five consecutive doses of 5-fluorouracil (10, 20, 30mg/kg b.w) at an interval of 24h and the control with 0.1ml-distilled water. Samples were obtained at 14, 35, 42 and 70 days after injection. Rats were sacrificed, a laparatomy was performed and epididymes were collected in 1ml phosphate buffered saline (pH 7.2), minced, filtered and stained with 1% aqueous eosin Y. An aliquot was taken in leucocyte pipette, diluted with phosphate buffered saline and sperm count was done as per the standard procedure. Data were analyzed by Mann Whitney U test. The results of this study revealed that 5 - fluorouracil significantly decreased the sperm count in a dose- and time-dependent manner.

PMID: 23365498 MyJurnal

This study was done compare the accuracy of non-contrast enhanced 3D time of flight magnetic resonance angiography (3D TOF MRA) with intraarterial digital subtraction angiography (IADSA) in depicting the arterial segments of the circle of Willis. 398 arterial segments were analysed from 38 patients who underwent both non-contrast enhanced 3D TOF MRA and IADSA examinations in Hospital Universiti Sains Malaysia from November 1998 to December 2000. Two observers performed blinded retrospective analysis of the IADSA images and Maximum Intensity Projection display of the 3D TOF MRA of the circle of Willis on separate sessions. Non-contrast enhanced 3D TOF MRA was sensitive and specific in depicting the A1, A2, M1, P1 and Anterior Communicating segments of the circle of Willis with a sensitivity ranging from 94.5% to 100% and specificity ranging from 90.5% to 100%. However it was poor in depicting the Posterior Communicating segments with a sensitivity of 21.4%. MIP display of the non-contrast enhanced 3D TOF MRA is sensitive in depicting the anatomy of the circle of Willis except for the PCOM segment. It is thus a reliable method for screening of this arterial circle.

Malays J Med Sci, 2003 Jan;10(1):13-26.

PMID: 23365496 MyJurnal

Cancer of the cervix has the potential to be eradicated since the initiating cause is known. There was not much known about this cancer until the time of the Renaissance. In Malaysia, it is the second most common cancer among females after breast cancer. The strategies on prevention in this country are still not optimal. This article highlights the problems and also discusses the pathogenesis of this disease. The key to prevention is screening and the future is the era of molecular pap smear.

PMID: 23365495

Newcastle disease virus (NDV) is one of the most economically important avian virus which affects the poultry industry worldwide. Although NDV is being very actively studied in Malaysia, there are still no studies on its potential as an anticancer agent, a new approach to treating cancer known as virotherapy. Currently, a collaborative research is being undertaken between Universiti Putra Malaysia (UPM), Universiti Sains Malaysia (USM) and Majlis Kanser Nasional (MAKNA) in characterising various local NDV isolates as anticancer agent. This paper describes an overview of the research that have been carried out worldwide in the use of NDV for cancer treatment and also some of our findings in characterising local NDVs with oncolytic properties.

Malays J Med Sci, 2000 Jan;7(1):27-32.

PMID: 22844212 MyJurnal

Experience of acute medical, surgical conditions, and clinical procedures of undergraduate students were assessed via a questionnaire survey during the final week of the 1993/1998 programme at the School of Medical Sciences, Univestiti Sains Malaysia. Individual performances were assessed by a scoring system. One hundred and twenty four students responded, (response rate 97%). More than 90% had seen myocardial infarction, cerebrovascular accident, pneumonia, respiratory distress, gastroenteritis, coma, and snake bite. Less than 33% had witnessed acute psychosis, diabetic ketoacidosis, acute hepatic failure, status epilepticus, near drowning, hypertensive encephalopathy, acute haemolysis or child abuse.Acute surgical/obstetrics cases, seen by >90% students, included fracture of long bones, head injury, acute abdominal pain, malpresentation and foetal distress. Less than 33% had observed epistaxis, sudden loss of vision, peritonitis or burns. Among operations only herniorrhaphy, Caesarian section, internal fixation of fracture and cataract extraction were seen by >80% students. The main deficits in clinical procedures are in rectal and vaginal examinations, urine collection and microscopic examinations. The performance of individual students, assessed by a scoring system, showed 15 students had unacceptably low scores (<149/230, 50%), 37 had good scores (>181.4/230, 70%) and 5 had superior scores (197.6/230, 80%).

Fulltext Helicobacter pylori related functional dyspepsia in a defined Malaysian population

Nafeeza MI, Isa MR, Kudva MV, Ishak MS, Mazlam MZ, Haron A, et al.

Malays J Med Sci, 2000 Jan;7(1):22-6.

PMID: 22844211 MyJurnal

The objective of the study was to determine the prevalence of H. pylori in functional dyspepsia among the three main races in Malaysia. Gastric antral biopsies from 233 (98 males, 135 females; age range: 17-75 years, mean age 39.5 years) patients attending the Universiti Kebangsaan Malaysia (UKM) gastroenterology clinic were assessed for the presence of H. pylori by culture and histology. About a third of the cases (79 of 233 (34%); 34 males, 45 females; mean age 42.6 yrs) were positive for H. pylori. The presence of H. pylori was always associated with antral gastritis. Malay patients were least likely to be positive for H. pylori (10 of 88 (11.4%); 5 males, 5 females; mean age 35.7 yrs) compared to the Chinese (43 of 95 (45%); 19 males; 24 females; mean age 40.2 yrs) and Indian patients (23 of 41 (56%); 10 males, 13 females; mean age 48.1 yrs). We found that H. pylori were most common among Chinese followed by Indians. However, the relative risk for the Indians was 8.58 and 6.29 for the Chinese compared to Malays. We conclude that the prevalence of H. pylori in patients with functional dyspepsia differs considerably with respect to ethnic groups.

An Innovation-Driven Approach to Specific Language Impairment Diagnosis

Ch'ng YH, Osman MA, Jong HY

Malays J Med Sci, 2021 Apr;28(2):161-170.

PMID: 33958970 DOI: 10.21315/mjms2021.28.2.15

Background: Specific language impairment (SLI) diagnosis is inconvenient due to manual procedures and hardware cost. Computer-aided SLI diagnosis has been proposed to counter these inconveniences. This study focuses on evaluating the feasibility of computer systems used to diagnose SLI.

Methods: The accuracy of Webgazer.js for software-based gaze tracking is tested under different lighting conditions. Predefined time delays of a prototype diagnosis task automation script are contrasted against with manual delays based on human time estimation to understand how automation influences diagnosis accuracy. SLI diagnosis binary classifier was built and tested based on randomised parameters. The obtained results were cross-compared to Singlims_ES.exe for equality.

Results: Webgazer.js achieved an average accuracy of 88.755% under global lighting conditions, 61.379% under low lighting conditions and 52.7% under face-focused lighting conditions. The diagnosis task automation script found to execute with actual time delays with a deviation percentage no more than 0.04%, while manually executing time delays based on human time estimation resulted in a deviation percentage of not more than 3.37%. One-tailed test probability value produced by both the newly built classifier and Singlims_ES were observed to be similar up to three decimal places.

Conclusion: The results obtained should serve as a foundation for further evaluation of computer tools to help speech language pathologists diagnose SLI.
