Introduction: It is still a challenge that the dissecting room has a place in learning gross anatomy. Understanding the students’ preference of learning tools is important to devise alternative teaching aids for improvement in learning anatomy. This study was conducted to assess student’s preference of learning tools available in the anatomy laboratory of an integrated curriculum.Methods: A cross-sectional comparative study was carried out for 4 weeks among 741 medical and dental students of International Islamic University Malaysia (IIUM), Universiti Teknologi MARA (UiTM), University Sabah Malaysia (UMS) and University Malaysia Sarawak (UNIMAS). Pre-tested, semi-structured, self-administrated questionnaires including open-ended questions were distributed. The data were analyzed by using SPSS 17.Results: Most of the participants were Malays (86%) and female (67%). The students from IIUM, UiTM, UMS and UNIMAS preferred the plastic model in terms of handability and application in examination (OSPE). It was statistically significant (p<0.05). In terms of understanding and information, the students of IIUM, UiTM and UMS preferred the plastic model while UNIMAS students preferred the prosected wet specimen over the plastic models. In terms of overall preference, students of IIUM and UiTM preferred the plastic model (85.8% and 44.1% respectively). In UNIMAS, their preference for the prosected wet specimen (90.7%) was slightly higher than for the plastic model (87.8%). UMS students preferred both cadaver (51.9%) and plastic model (50%). Conclusion: Most of the students preferred the plastic model as the best learning tool in studying gross anatomy. This study suggests that plastic model may hold a role in enhancing students’ learning of gross anatomy in an integrated curriculum.

Objective: Rheumatoid arthritis (RA) is a chronic inflammatory condition that can be associated with abnormal bone turnover and hence osteoporosis. Osteocalcin (OC) levels are increased in conditions with high bone turnover, including high RA disease activity. Thus, OC levels could possibly be used as a marker to assess bone health and disease activity in RA patients. As there have been no previous studies looking at serum OC levels in Malaysian RA patients, this study was performed to examine possible correlations between OC, bone mineral density (BMD) and disease activity in this population.Methods: A cross-sectional study of 75 female RA patients and 29 healthy controls was performed. Serum OC was measured using a Quantikine® ELISA kit. Dual-energy x-ray absorptiometry (DXA) was used to assess BMD.Results: Serum OC levels were not significantly different between RA patients (median 14.44 ng/mL, interquartile range [IQR 12.99]) compared to healthy controls (median 11.04 ng/mL IQR 12.29) (p=0.198). Serum OC increased with age (Spearman’s rho r=0.230, p=0.047). There was no significant correlation between serum OC and body mass index (BMI), menopause status, BMD, DAS28, swollen or tender joint counts. Overall, there were 11 (14.7%) patients with osteoporosis and 27 (36.0%) with osteopenia. Menopause status was significantly associated with BMD at all sites (lumbar spine p=0.002, femoral neck p=0.004, total hip p=0.002). Conclusions: Serum OC were similar in RA patients compared to healthy controls. In RA patients, serum OC did not correlate with RA disease activity or BMD. Menopause status remains an important influence on BMD. Thus, measuring serum OC levels in Malaysian RA patients was not useful in identifying those at risk of low BMD.

Tumoral calcinosis is an uncommon condition which has been described to exist in primary and secondary forms. A lack of awareness of this entity can lead to unnecessary procedures and incorrect management. We report a case of a patient on peritoneal dialysis who presented with multiple painful joint swellings to the orthopaedic department. An initial diagnosis of septic arthritis was made, then revised to chronic tophaceous gout and referred to the rheumatology unit.

ervical spine injury is commonly associated with road-traffic accidents. The true incidence of cervical spine injuries is unknown due to under-reporting of such injuries. Cervical spine injury is associated with high morbidity and mortality if it is missed. With the advancement of imaging modalities, the number of missed cervical injuries has reduced. Nevertheless, some clinicians are dependent solely on imaging tools to rule out cervical spine injury in a trauma victim. We report two cases of “near miss” C6 fracture to highlight the importance of a detailed clinical history and clinical examination with imaging as an adjunct to rule out cervical injury.
5.Amoebic colitis with liver abscess
International e-Journal of Science, Medicine and Education 2018;12(1):27-31
moebiasis is a parasitic infection caused by the intestinal protozoan Entamoeba histolytica, most prevalent in developing countries. It results in 40,000 to 100,000 deaths each year from amoebic colitis and extra intestinal infections. Amoebic liver abscess (ALA) is the most common extra intestinal site of infection with an incidence of between 3% and 9% of all cases of amoebiasis. Ultrasound which has a sensitivity of more than 90% for detecting ALA is highly recommended as an initial investigation followed by serological demonstration of circulating antibodies specific to Entamoeba histolytica.

Background: The importance of tooth sectioning
is realized in disasters such as earthquake, airplane
crash investigation, terror, micro leakage studies, age
estimation etc. The objective of this study was to develop
a simple method to make thin sections (approximately
100 mm) from freshly extracted teeth.
Methods: One hundred and twenty human premolars
recently extracted for orthodontic purpose were used for
this study. The teeth were stored in 0.5% chorlaramine
for 2 weeks and were not allowed to dry at any stage
of the experiment. The teeth were thoroughly washed
in distilled water teeth and then were sectioned
buccolingually from crown to the root portion.
Results: A detailed embedding-cutting-mounting
procedure is described. The prepared thin ground
sections were then examined under a Polarised light
microscope for the enamel and the dentine, as well as
the caries lesions can clearly be distinguished.
Conclusion: This is an effective and efficient method
for preparation of ground sections in which the hard
tissue details are preserved.

Morning surge in blood pressure is an
independent cardiovascular risk factor in the middleaged
and the elderly. Whether such a surge occurs in
young subjects is not known. Eighty normotensive
subjects (age: 21.8 ± 1.3 yr) measured their own blood
pressure (BP) using an automatic device (Omron
HEM-7080,) on going to bed and on waking up, for 2
consecutive days. In contrast to large morning BP surges
reported for older age groups, there was much smaller
but significant (P<0.002) rise only in the DBP (1.9 ±
5 mm Hg) on waking up on day 2 in young subjects.
The duration of sleep and the time the subjects slept
influence the sleep-wake BP change.

Background: Clinical clerkship in a busy hospital
environment forms an important part of undergraduate
medical training. Regular objective assessment of this
activity with feedback would be expected to improve
outcome.
Methods: We implemented fortnightly clinical
assessments using modified OSLER (Objective
Structured Long Examination Record), and over a
6-week clinical rotation. Modifications included
provision of individualized feedback. The assessment
process was evaluated by both students and teachers
via a questionnaire measuring their perceived
educational impact, feasibility and acceptability.
Results: Students agreed that the patient spectrum was
appropriate and fair, resulting in improved history taking
and presentation skills (96.6%), clinical examination
skills (89%) and clinical reasoning skills (90.7%).
It was graded to have helped learning “tremendously”
and “moderately” by 64.7% and 32.8% of students
respectively. Perceived improvement was attributable
mainly to the repetitive nature of the assessments since
only 63% of students were provided with feedback.
96.6% of students and 94.1% of assessors perceived
the format created a stressful but positive learning
environment. 52.9% of assessors agreed that the exercise
consumed significant time and resources but 88.2% rated
it as manageable and supported its continuation.
Conclusion: Frequent and regular in-course clinical
assessments with emphasis on individual feedback
is feasible, acceptable and has significant positive
educational impact.

Background: Database on hospital records like discharge
data, birth and death certificates are widely used for
epidemiological and research studies. However there are
a very few validation studies on these data. The aim of
this study was to validate and assess the accuracy of the
ICD 10 database on congenital anomalies in the state of
Penang. This study was carried out for three years, from
2002 to 2004.
Methods: The list of cases coded under the general coding
“Q” was extracted and approximately 30% of cases were
randomly selected from the list. Medical records for the
selected cases were checked and discrepancies for the
diagnoses between the medical records and the ICD 10
data base were recorded for three years. Verification was
done for basic demographic variables and the coding of
the diseases. Discrepancies, sensitivity and specificity
were calculated.
Results: The ICD 10 database for congenital anomalies
are classified into two types: Type 1 and Type 2.
Discrepancies on demographic information were found
among the age of patients (babies with congenital
anomalies). In Type 1, there was a discrepancy of about
0.02 % to 0.05% probability that a congenital anomaly
case can be recorded as non congenital anomaly in
the ICD 10. In Type 2 there was a discrepancy that a
non-congenital anomaly was classified as congenital
anomaly and this ranged from 26.7% to 50.0%. The
sensitivity ranged from 96.85% to 97.98%, thus it can
be concluded the ICD 10 database is highly sensitive
while the specificity ranged from 50.00% to 78.57 %. In
other words the ICD 10 is not accurate when classifying
the non- congenital anomaly cases. A fair percentage of
non-congenital anomaly cases were classified as CA in
the ICD 10 database.
Conclusion: Even though hospital databases are
used as a baseline data for a number of research and
epidemiological studies it cannot be used at face
value. Validation of these data is necessary before any
conclusions can be drawn or intervention measures are
undertaken.

Ramon Chin Beng Ong ; Patricia Kim Chooi Lim ; Joon Wah Mak
International e-Journal of Science, Medicine and Education 2011;5(2):18-28
Background: Many proteins released by cells to the
blood and other fluids are glycoproteins. One set of
glycoproteins carry the ABO blood group determinants
and glycoproteins have been shown to be vital in
determining the structure and organization of plasma
membranes. There is evidence suggesting their important
role in cell-to-cell contact, adhesion, hormone
interaction and vital transformation. Differences in
proteins and glycoproteins in the different human
blood groups may influence the invasion process of
Plasmodium falciparum. The objectives of the study were
to determine whether there are any changes in proteins
and glycoproteins of red blood cells upon infection by
P. falciparum and whether these protein and glycoprotein
changes differ in the various ABO blood groups.
Methods: A Malaysian strain of P. falciparum was cultured
in vitro in red blood cells from A, B, O and AB blood
groups. Protein and glycoprotein profiles of uninfected
and P. falciparum- infected red blood cells from the
different human ABO blood groups were analyzed by
SDS-PAGE. For protein bands, the gels were stained
with Coomassie blue while glycoproteins were visualized
following staining of gels using GelCode® Glycoprotein
Staining Kit.
Results: Cell membranes of P. falciparum infected
erythrocytes from different ABO blood groups have
different glycoprotein profiles compared to uninfected
cells. All the infected samples showed a prominent
protein band of molecular weight 99 kDa which was
not present in any of the uninfected samples while a
48 kDa band was seen in four out of the seven infected
samples. The erythrocyte cell membranes of A and AB
blood groups showed different glycoprotein profiles upon
infection with P. falciparum when compared to those
from blood groups B and O.
Conclusion: The two glycoproteins of molecular
weights 99 kDa and 48 kDa should be further studied to
determine their roles in the pathogenesis of malaria and
as potential targets for drug and vaccine development
