1.Qualitative Phytochemical Analysis and Antimicrobial Activity of Piper sarmentosum Leaves Extract against Selected Pathogens
Malaysian Journal of Health Sciences 2019;17(1):67-72
The controversial usage of antiseptic in treating wound infections had become a huge issue over the years due to its minimal effectiveness and high toxicity level that are harmful to humans. Hence, numerous studies had been carried out to determine other possible approaches including herbal remedies. The alarming situation had led us to study on Piper sarmentosum and its antimicrobial activity against selected pathogens. In present study, methanol extract of Piper sarmentosum leaves were prepared to investigate the presence of phytochemical compounds. The in vitro antimicrobial activity of crude methanolic extract was evaluated using disc diffusion and microdilution broth methods. The study demonstrated the antimicrobial activity of leaves extract against Staphylococcus aureus (7 mm) and Escherichia coli (6.5 mm). However, no zone of inhibition was observed against Pseudomonas aeruginosa. Meanwhile, the MIC values for Staphylococcus aureus was 6.25 mg/mL whilst Escherichia coli was 12.5 mg/mL. In addition, the phytochemical screening results revealed that the extract contained glycosides, flavonoids, terpenoids, alkaloids, and phenolics. In conclusion, methanolic extract of Piper sarmentosum leaves has the potential as a new, effective alternative towards current drugs that are available for skin-associated infection. The findings from this study are crucial in providing latest information of the plant’s additional values that can be incorporated as a baseline for current and future studies as well as in investigating other possible plants that are beneficial for health purposes, particularly for combating skin-associated infection.

3.Rapid onset of facial swelling - Answers.
Brunei International Medical Journal 2010;6(1):72-72
(Refer to page 51)
Answer: Spontaneous bilateral periorbital
haematoma associated with
acute promyelocytic leukemia
In this patient, the spontaneous bilateral periorbital
haematoma could be due to severe
thrombocytopenia. However the presence of
abnormal promyelocytes in the peripheral
blood smear (Panel, darkly stained cells
are promyelocytes) is suggestive of acute
promyelocytic leukemia (APL) which should
be confirmed with a bone marrow biopsy,
cytogenetic study for t(15;17) and molecular
study for PML-RARa oncogene fusion.
4.Prevalence of gastrointestinal nematodiasis and coccidiosis in goats from three selected farms in Terengganu, Malaysia
Asian Pacific Journal of Tropical Biomedicine 2016;6(9):735-739
Objective: To reveal the prevalence of gastrointestinal nematodiasis, Trichostrogylus, Haemonchus, Strongyloides and Trichuris and coccidiosis, mainly Eimeria in kids, yearlings and adult goats. Methods: A total of 287 goat faecal specimens were randomly collected from three farms in Kuala Terengganu, Setiu and Besut. Results: Prevalence of coccidiosis (89.2%) was significantly higher (P < 0.05) than gastrointestinal nematodiasis (52.3%). Gastrointestinal nematodes (GINs) were found in 37.0% kids, 63.5% yearlings and 53.3% adults. Identification of GINs revealed the predominance of Strongyloides (45.6%) followed by Trichostrogylus (12.9%), Hae-monchus (11.8%) and Trichuris (8.7%) in all groups whereby the adult goats recorded the highest infections of Trichostrogylus (20.5%), Haemonchus (10.6%), Strongyloides (51.5%) in all groups. The age-specific intensity for Eimeria was in following order:kids (92.6%), adults (86.6%) and yearlings (51.5%) and the difference was not significant (P > 0.05). The concurrent infections between GINs and Eimeria were 67.94% in all groups. Polyparasitisms of Trichostrongylus (17.4%), Haemonchus (15.15%) and Strongyloides (40.4%) with Eimeria had infected most adult goats. Dual infections of Trichostrongylus with Eimeria and Trichuris with Eimeria were significantly higher in adults than yearlings and kids (P<0.05). Conclusions: GINs and Eimeria were widely distributed in the goats leading to higher risk of morbidity and mortality.

Failure in achieving abstinence in methamphetamine dependence population is a common scenario.
The use of methamphetamine in pregnancy however, was not so often brought to attention. This report
highlights the challenges and issues encountered in the management of a pregnant lady with the problem
of methamphetamine dependence, who presented with psychosis. Among the areas outlined were issues
in commencing treatment for methamphetamine psychosis, presence of psychosocial conditions that
impeded total abstinence and the risks of methamphetamine use during pregnancy.

6.Nutrition-Related Factors and Binge Eating Behaviour in a Sample of Malaysian University Students
Malaysian Journal of Health Sciences 2019;17(1):57-65
Binge eating (BE) behaviour is associated with obesity and eating disorders. This cross-sectional study investigates BE behaviour and its relationship with nutrition-related factors among university students. A total of 170 (69% females) university students in Malaysia aged 19 to 24 years participated in this study. BE behaviour was assessed with the use of Binge Eating Scale (BES) questionnaire. Socio-demographic background and nutritional status (anthropometric measurements, body mass index (BMI) and dietary intake) were also measured. BE behaviour reported by 10% percent of the participants. BE behaviour was associated with increased energy intake, elevated BMI and sex (Adjusted R2 = 0.116, p < 0.001). Differences in sex-specific factors in predicting the risk of BE behaviour were evident. In male participants, an increased in energy intake, elevated BMI and had a higher waist circumference associated with the risk of BE behaviour (Adjusted R2 = 0.411, p < 0.001). In female participants, only a higher waist circumference associated with BE behaviour (Adjusted R2 = 0.028, p < 0.05). The finding suggests that understanding sex-specific factors are necessary to prevent BE. These are the potential targets for tailored eating behaviour intervention among university students.

·AIM: To present a case of Coats' disease in adult and to illustrate the retinal findings.·METHODS: A case report.·RESULTS: A 63 years old Malay man, a known case of diabetes mellitus, presented with one year history of painless and progressive reduced vision in the right eye. Right eye visual acuity was counting finger 2 feet while left eye best corrected visual acuity was 6/12. Right fundus showed presence of extensive subretinal exudates at the temporal part of the posterior pole involving the macular area and nasal to the optic disc. It was associated with multiple areas of abnormal blood vessels temporal to the macula with attenuated vessels. Fundus fluorescein angiography(FFA) showed presence of telangiectatic vessels at the area of subretinal exudates and leakage of fluorescein from the telangiectatic vessels. The left eye was normal. Based on clinical and FFA findings, he was diagnosed to have adult Coats' disease. The right eye was treated with argon laser photocoagulation. Six months post laser, his visual acuity remained at 6/120 and there was minimal regression of the disease seen in the retina. ·CONCLUSION: The clinical and angiographic findings are important in diagnosing retinal telangiectasia. Treatment by laser photocoagulation in area of leakages may be beneficial in preventing visual loss.

Dengue virus infection has been posing alarming economic and social burden on
affected nations. It is estimated that 50-100 million dengue infections occur annually with
over 2.5 billion people at risk for endemic transmission. In the effort to develop effective
antiviral agents, we previously reported potential antiviral activities from selected array of
natural products and compounds against dengue virus serotype 2 (DV2). In this study, we
report the synthesis of two efficacious novel compounds, YK51 and YK73, and their activities
against DV2 replication. Both compounds were chemically synthesised from nicotinic acid
using a modified method for the synthesis of dihydropyridine. The products were tested with
cell-based assays against DV2 followed by a serine protease assay. As a result, both YK51 and
YK73 exhibited intriguing antiviral properties with EC50 of 3.2 and 2.4 µM, respectively. In
addition, YK51 and YK73 were found to attenuate the synthesis of intracellular viral RNA and
protect the switching of non-classic mechanism of protein translation. These compounds
demonstrated inhibitory properties toward the activity of DV2 serine protease in a dose
dependent manner. These findings demonstrate that both YK51 and YK73 serve as DV2 serine
protease inhibitors that abrogate viral RNA synthesis and translation. Further investigation
on these compounds to corroborate its therapeutic properties towards dengue is warranted.
