3.Posterior Restoration Selection Among General Dental Practices in Malaysia: A Preliminary Study
The International Medical Journal Malaysia 2019;18(2):53-58
Introduction: Tooth restoration is a common, routine procedure among dentists but still has its own
difficulties especially for posterior teeth. As it is a straightforward procedure, some dentists are not aware of
the difficulties that may contribute in reducing the longevity of the filling. The aim of the study is to
determine the difficulties encountered during and after placement of restorative materials in deep cavities.
Materials and methods: Standardized questionnaires were divided randomly among general private
dental practitioners in Kuala Lumpur. Chi-square test was used to determine any significant factors
associated with difficulties of material placement. Results: This study showed that the most frequent
difficulties encountered among practitioners were to obtain good moisture control (39.0%). No significant
association was found between obtaining good moisture control and year of clinical experience (p= 0.286)
and also place of graduation with the manipulation of the materials (p= 0.542). Conclusion: Dental
practitioners claimed that it was difficult to obtain good moisture control in placement of posterior
restoration. Thus, it is an obligation of dental practitioners to practice proper isolation and good
manipulation of materials on posterior restoration.
4.A rare case of large sphenoethmoidal osteoma

The Medical Journal of Malaysia 2017;72(1):60-61
Osteoma is the most common benign tumour of the nose
and paranasal sinuses. However, involvement of the
sphenoid sinus by osteoma is rare. Most of the time,
patients with paranasal sinus osteoma are asymptomatic.
However, symptoms may present, depending on the location
and extension of the tumour. We report a case of a patient
with sphenoethmoidal osteoma found incidentally on
imaging, with evidence of impingement onto the optic nerve
at the optic canal. However, the patient was asymptomatic.
He was surgically treated using the endoscopic transnasal
approach.

5.Increased Biceps Translation: A Clinical Sign of Complete Distal Biceps Tendon Rupture.
Clinics in Shoulder and Elbow 2016;19(1):48-50
Various tests to help in the clinical diagnosis of distal biceps tendon ruptures have been described. In our experience these tests are painful in the acute setting. We suggest a simple alternative test wherein the biceps muscle belly is held by the examiner and translated medially and laterally. This is done with the forearm flexed to 90 degrees. It is first performed with the biceps relaxed and subsequently performed with the forearm flexed against resistance. In the relaxed forearm the biceps easily translates over 50% of its width. When placed under tension (by flexing against resistance) this translation is significantly reduced. In cases of complete distal biceps tendon rupture, the biceps still translates, even under resisted flexion of the forearm. This simple test is less painful than other described tests, is easy to perform, and aids in clinical diagnosis of distal biceps tendon ruptures.

6.Medical Ethics: What You Should Know?
International Journal of Public Health Research 2012;2(1):129-136
Medical ethics is a system of moral principles that apply values and judgments to the practice of medicine. As a scholarly discipline, medical ethics encompasses its practical application in clinical settings as well as work on its history, philosophy, theology, and sociology. The medical profession has long subscribed to a body of ethical statements developed primarily for the benefit of the patient. A physician must recognize responsibility to patients first and foremost, as well as to society, to other health professionals, and to self. This paper presents some information regarding medical ethics, including the values and principles of ethical conduct. Later the requirements of consent form is presented to guide the researchers before conducting a study.

Teachers face one of the highest demands of any professional group to use their voices at work. Thus, they are at
higher risk of developing voice disorder than the general population. The consequences of voice disorder may have
impact on teacher’s social and professional life as well as their mental, physical and emotional state and their
ability to communicate. Objectives of this study are to determine the prevalence of voice disorder and the
relationship between voice disorder with associated risk factors such as teaching activities and lifestyle factors
among primary school teachers in Bintulu, Sarawak. A cross sectional study was conducted based on random sample
of 4 primary schools in Bintulu, Sarawak between January-March 2014. A total of 100 full-time primary school
teachers were invited to participate in the study. Data were collected through a self-administered questionnaire
addressing the prevalence of voice disorder and potential risk factors. Descriptive analysis and chi-square test was
used to measure the relationship between voice disorder and associated risk factors. The response rate for this study
was 78% (78/100). The study found that the prevalence of voice disorder among primary school teachers in Bintulu,
Sarawak was 13%. Chi-square test results revealed that factors significantly associated with voice disorder (p<0.05)
were smoking (p=0.012), consuming alcohol beverages (p=0.012) for lifestyle factors while teaching session (p=0.049)
for teaching activities. A low prevalence of voice disorder exists among primary school teachers in Bintulu, Sarawak.
Smoking, consuming alcohol beverages and teaching session has proven to be significantly associated causing voice
disorder among them.
8.Adherence of Streptococcus pneumoniae and expression analysis of neuraminidase gene (NanA and NanB) after interaction of A549 human lung epithelial cells with pneumococcal strains of various serotypes
Malaysian Journal of Microbiology 2017;13(3):210-216
Aims: Streptococcus pneumoniae is the most common bacterial respiratory pathogen that can lead to invasive diseases
such as pneumonia, bacteremia, and meningitis. The interaction of S. pneumoniae with host respiratory epithelial cells is
crucial in the colonization of human respiratory tract and involve in the virulence. The aim of the study is to investigate
the adherence of S. pneumoniae and the effect of serotypic variation on neuraminidase genes (NanA and NanB) after
interaction of A549 human lung epithelial cells with S. pneumoniae serotypes.
Methodology and results: Six different serotypes of S. pneumoniae were used (1, 3, 5, 19F, 23F, and 14). A549
human lung epithelial cells were inoculated with pneumococcal strains of different serotype for 3 hours. The number of
adherent bacteria was determined by serial dilution followed by spread plate technique on tryptic soy agar supplemented
with 5% sheep blood. Bacterial RNA was harvested from the infected A549 cells. The differential expression level of
neuraminidases was observed by quantitative real-time PCR (qRT-PCR). Based on bacterial adherence assay, serotype
14 showed highest adherence, meanwhile, serotype 23F showed lowest adherence. This suggests that serotype 14 has
a better affinity to adhere to A549 cells as compared to serotype 23F. Higher NanA gene expression was observed in
serotype 5, 23F and 19F, while lower expression in serotype 14. In contrast, NanB gene shows low-level expression in
serotype 23F and 19F, while higher expression in serotype 14. This postulates that NanA and NanB gene may have
different functions in the pathogenesis of S. pneumoniae.
Conclusion, significance and impact of study: Our finding on differential expression of neuraminidase gene of S.
pneumoniae of various serotypes on A549 cells might give a better understanding of host pathogen interaction between
bacteria serotypes and host cell.
10.Villoglandular adenocarcinoma of cervix--a tumour with bland cytological features: report of a case missed on cytology.
The Malaysian journal of pathology 2003;25(2):139-43
The diagnosis of villoglandular adenocarcinoma of cervix on cytological smears is often missed due to the relatively bland cytological features of this tumour. A 45-year-old female with an exophytic cervical growth had three cervical smears reported as unsatisfactory. A cervical biopsy followed by Wertheim's hysterectomy showed a villoglandular adenocarcinoma (VGA) of cervix. Vaginal recurrence of VGA was again missed on the first post-operative vault smear. The second and third vault smears showed characteristic features of VGA that enabled correct identification. Review of some of the smears previously reported as unsatisfactory showed architectural features of VGA in the three dimensional (3-D) fragments that were previously considered to be benign.
