Introduction: Embolisation has long been used as an adjunct to surgical resection in the treatment of brain arteriovenous malformation (bAVM). The most commonly used embolic material, n-butylcyanoacrylate glue, requires experience and skill to handle its quick and unpredictable flow and polymerisation. A new liquid embolic agent, ethylene vinyl alcohol copolymer (Onyx), is less adhesive and polymerises slowly, which provides better control for radiologists performing embolisation. Objective: To report our experience in embolisation using Onyx alone or in combination with histoacryl for bAVM embolisation in our tertiary referral centre. Methods: We retrospectively reviewed the anatomy, technical conditions, complications and clinical outcome of all bAVM patients embolised at our centre using Onyx alone or in combination with n-butylcyanoacrylate glue. Results: Between 2010 and 2013, 13 patients [6 (46.2%) male; 7 (53.8%) female; aged, 14– 57 years] were included, and a total of 31 embolisations were performed. Clinical presentation included hemorrhage [9 (69.2%)], seizures [2 (15.4%)], and headache [2 (15.4%)]. Most AVMs were located in the brain hemispheres [12 (92.3%)] and measured <3 cm [7 (53.8%]. Complete occlusion of the AVM was obtained in 2 (15.4%) patients; 11 (84.6%) patients had partial occlusion [6 (54.5%) had <50% nidus occlusion]. Complications occurred in four procedures involving 3 patients (morbidity, 23.1%). This resulted in the death of 1 patient (mortality, 7.7%) and complete recovery with no disability in 2 patients. Conclusion: The total nidal occlusion achieved herein is comparable to other similar studies. Our morbidity and mortality were higher compared to other studies which may be attributed to the small number of patients. More data is being collected which may better reflect on our experience.

Clival chordoma is a rare primary bone tumour that arises from the remnant of the notochord and typically occurs in older adults. Upon imaging, the tumour can be seen arising from the clivus and causes clival destruction. This usually provides insight for a diagnosis. Here we present a case of a non-enhancing, pre-pontine mass that was hypointense on T1W and hyperintense on T2W in an adolescent. No clival bone erosion was observed. Based on the age group, imaging findings, and lack of clival erosion, a provisional diagnosis of epidermoid cyst was made and the tumour was resected. This patient was eventually diagnosed with a clival chordoma based on histopathological examination.

Introduction: Iontophoresis of vasoactive substances such as acetylcholine (ACh) and sodium nitroprusside (SNP) combined with Laser Doppler fluximetry (LDF) is a non-invasive tool used to determine microvascular endothelial function. This study aims to test the effect of sodium chloride on non-specific vasodilatation when used as a vehicle in the process of iontophoresis. This study also aims to define the number of current pulses needed to get the maximum effect during iontophoresis with ACh and SNP using low current strength. Methods: The experiment was conducted in five healthy females. Baseline skin perfusion was taken before administration of seven current pulses. Current strength of 0.007 mA and current density of 0.01 mA/cm2 were used. Acetylcholine was used to assess endothelial dependent vasodilatation, while SNP was used to assess endothelial independent vasodilatation. The mean skin perfusion (AU) responses to the iontophoresis of ACh at the anodal and SNP at the cathode leads were recorded. Sodium chloride (0.9%) was used as a vehicle to obtain concentration of 1% for both ACh and SNP. Iontophoresis of pure vehicle (NaCl) was conducted on a separate day to observe the effect of vehicle only on the iontophoresis process at both anode and cathode. Results: Iontophoresis of NaCl showed no significant increase in perfusion compared to baseline at both anode and cathode. Significant increases in skin perfusion were observed with SNP and ACh; a plateau of ACh was reached from the 3rd pulse onwards; while the plateau of SNP was reached from the 4th pulse onwards. Conclusion: NaCl could be used as a vehicle for Ach and SNP during iontophoresis as it did not cause non-specific vasodilatation. Using five current pulses are adequate for iontophoresis of ACh and SNP to assess microvascular endothelial function.

Aims: The aquaculture industry has been identified as one of the sources for the emergence of antimicrobial resistant bacteria. This study aimed to determine the level of bacterial contamination from selected catfish pond farming at Jasin, Melaka and its susceptibility to antimicrobial agents. The correlation between the sampling points’ Water Quality Index and the level of bacterial contamination was also determined. Methodology and results : Sampling was carried out at six sampling points of the river as well as selected catfish pond farming. Microbial counts were assessed using the membrane filtration and isolates were further identified by using the polymerase chain reaction (PCR) method. Antimicrobial susceptibility tests were carried out using the disk diffusion method. Results showed that the total bacterial count obtained was not significantly different (P>0.05) between sampling points with an average of 4.47 ± 0.41 log CFU/mL. A total of 27 different bacterial species were identified where 63% were identified as Gram-negative bacteria. A medium negative correlation (r=-6.16, P<0.01) was found between the sampling points’ Water Quality Index and the level of bacterial contamination. Among bacterial species identified, 18 species are pathogenic strains. Conclusion, significance and impact of study Antibiotic susceptibility test indicated that only 4 isolates showed resistance to antimicrobials tested and the study shows the potential cross contamination between fishponds and Kesang River, Melaka. Thus, public health concerns are tangible, and prevention of the cross contamination is crucial for the farm.

Objectives: Body weight perception may determine the practice of proper weight management. The objective of this study was to measure the agreement between body weight perception and actual body weight status and its associated factors among late adolescents in Kuantan, Malaysia. Methods: A cross-sectional study was conducted from April to October 2018 among 479 adolescents aged 17-19 years old from seven institutions of higher learning in Kuantan. Body weight status was described as body mass index (BMI). Weight and height were measured, and BMI was calculated. Validated, self-administered Figure Rating Scale (FRS) questionnaires were used. Agreement between BMI and body weight perception was calculated using Kappa statistics. Logistic regression was employed to examine the association between body weight perception and sociodemographic variables. Results: More than one-third (35.3%) of the respondents misjudged their own body weight. More than one third of the respondents (38.7%) who were underweight, misperceived themselves as having normal weight whilst 31.7% of obese respondents identified themselves as overweight. The agreement between body weight perception and body mass index was moderate (k0.46, p<0.01). Conclusion: Body weight perception was in moderate agreement with actual weight in late adolescents. Accurate body weight perception is an important factor in late adolescent’s weight management behaviour. Hence, health education related to body weight management should be emphasized among this age group.

Background: Menopause signifies the beginning of a non-reproductive phase from the reproductive period. Although it is considered a natural life transition, recent studies have indicated that a woman’s menopausal experience may impact her quality of life. While studies have examined Malaysian women’s knowledge and awareness of menopause, they have focused on the prevalence of menopausal symptoms and sociocultural aspects. These investigations also used a quantitative design that may have limited the information regarding the nature and experience of menopause. Objectives: This study explores women’s perceptions and understanding of their menopausal experience. Methods: A total of 20 menopausal women were recruited using purposive sampling through social media in the state of Pahang, Malaysia. In-depth semi-structured interviews were used to explore how they perceived their menopausal experience. The data were then analyzed using thematic analysis. Results: Three themes that emerged from the findings included perceptions of menopause, biopsychosocial changes and help-seeking behavior. For many Muslim women, menopause was perceived as a time for them to engage in religious commitment more than they had before. Conclusion: The study findings uncovered a knowledge gap and a lack of support for women impacted by menopause. Muslim women regarded their menopause phase as a time for them to engage in religious duty fully. These results indicate the need for a psychosocial intervention and educational program to ensure women a better transition throughout their menopausal phase
