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.

A 59-year-old woman presented with a two-week history of spontaneous gum bleeding and easy bruising. Her full blood count on admission showed pancytopenia with haemoglobin of 96 gm/L, total white cell count of 1.6 x 109/L (absolute neutrophil count of 0.26 x 109/L) and platelet count of 17.0 x 109/L. Peripheral blood film showed a few abnormal hypergranular promyelocytes present. Five days later she developed the above signs. What is the diagnosis? Answer: refer to page 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.

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.

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.

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.

Entamoeba histolytica infection is widespread worldwide and higher prevalence is usually seen among the indigenous under priviledged people living in the tropics and subtropics. Seventy one Orang Asli children from Pos Lenjang, Pahang participated in this study and were grouped according to age and gender. Faecal samples were collected and examined for the presence of Entamoeba histolytica using 3 different diagnostic techniques namely the direct faecal smear, formalin ether concentration and trichrome staining.The prevalence of Entamoeba histolytica infection among the Orang Asli children at Pos Lenjang, Pahang was high at 22.5%. According to gender, female children showed higher prevalence (32.5%) compared to male at only 9.7%. Infection was also apparently higher among the school going children at 32.4% compared to preschool children (11.8%). The high prevalence of Entamoeba histolytica infection amongst the Orang Asli children at Pos Lenjang is related to several factors including low socioeconomic status, lack of basic amenities, culture, and poor knowledge on healthy life practice.
