Background: No previous study has assessed the impact of childhood disability on parents and family in the context of Malaysia, and no instrument to measure this impact has previously been available. The objective of this cross-sectional study was to determine the reliability of a Malay version of the PedsQL™ Family Impact Module that measures the impact of children with disabilities (CWD) on their parents and family in a Malaysian context. Methods: The study was conducted in 2009. The questionnaire was translated forward and backward before it was administered to 44 caregivers of CWD to determine the internal consistency reliability. The test for Cronbach’s alpha was performed. Results: The internal consistency reliability was good. The Cronbach’s alpha for all domains was above 0.7, ranging from 0.73 to 0.895. Conclusion: The Malay version of the PedsQL™ Family Impact Module showed evidence of good internal consistency reliability. However, future studies with a larger sample size are necessary before the module can be recommended as a tool to measure the impact of disability on Malay-speaking Malaysian families.

BACKGROUND: Chronic rhinosinusitis (CRS) is one of the most common and complex chronic inflammatory disease of sinonasal mucosa. Even though the pathogenesis of CRS is multifactorial and still unclear, the role of cytokines especially interleukin-1 (IL-1) is being investigated worldwide in different population because of varying results obtained. OBJECTIVE: To study the association of IL-1 (A and B) gene polymorphisms with chronic rhinosinusitis with nasal polyp (CRSwNP) and without nasal polyp (CRSsNP), and other factors related. METHODS: This is a case-controlled study which include a total of 138 subjects recruited from Otorhinolaryngology-Head and Neck Surgery clinic in Hospital Universiti Sains Malaysia. Genotyping of the IL-1A (+4845G, +4845T) and IL-1B (−511C, −511T) were performed with restriction fragment length polymorphism analysis. RESULTS: There was a statistical significant association between IL-1B (−511C, −511T) polymorphism with CRSwNP and CRSsNP (p < 0.001). The CT genotype of IL-1B was markedly increased in CRSwNP subjects (52.2%). However, there was no significant association found between IL-1A (+4845G, +4845T) with CRSwNP and CRSsNP (p = 0.093). No association was found in factors related to CRS, which included asthma, atopy, allergy, aspirin sensitivity, and family history of nasal polyp (p value of 0.382, 0.382, 0.144, >0.95, and 0.254, respectively). CONCLUSION: This study indicates an association of IL-1B (−511C, −511T) polymorphism with CRSwNP and CRSsNP in our population, hence there is a possibility of IL-1B involvement in modulating pathogenesis of CRS. There was no significant association of IL-1A (+4845G, +4845T) polymorphism with CRSwNP and CRSsNP, and other factors related.

Objective: To investigate the antibacterial activities of green vegetables (pennywort, mint, garlic, parsley and celery) against four common enteric bacteria [Salmonella enterica (ATCC 25957) (S. enterica), Shigella flexneri (ATCC 12022) (S. flexneri), Escherichia coli (ATCC 43889) (E. coli) and Enterobacter cloacae (ATCC 13047) (E. cloacae)] as an alternative medicine for controlling food borne diarrhea disease and the synergistic effect of green vegetables against those bacteria. Methods: Five common vegetables (pennywort, mint, garlic, parsley and celery) were purchased and extracted. The antimicrobial activities of these extracts were tested against four common enteric bacteria (S. enterica, S. flexneri, E. coli and E. cloacae). Ten different concentrations of the extracts (from 640 to 1.25 mg/mL) were prepared and used for the study. The minimal inhibitory concentration (MIC) was determined by the broth dilution method. The antimicrobial activities were assessed by using both well diffusion and disc diffusion methods. Results: Garlic extract showed excellent inhibitory effects on all enteric bacteria. Other plants (parsley, celery, mint and pennywort) were not effective against enteric bacteria. The MIC of garlic against S. flexneri and E. cloacae was 40 mg/mL. The MIC of S. enterica and E. coli were 20 and 10 mg/mL, respectively. The performance of the well diffusion method was better than that of the disc diffusion method with clear and sharp inhibition zones of tested bacteria against plant extracts. Conclusions: Garlic had excellent antimicrobial effects against enteric bacteria and was recommended to be given to patients with gastroenteritis. The other vegetables (pennywort, mint, parsley and celery) showed no inhibitory effects on enteric bacteria but still can be used for its richness in vitamins and fibers. The performance of the well diffusion method was better than that of the disc diffusion method in detecting the antibacterial effects of green vegetables.

Introduction: Early studies have suggested the role of C-C chemokine receptor type 5 (CCR5) polymorphisms in influencing HIV pathogenesis and phenotypes, including the protection against HIV infection and delaying disease progression to AIDS. This study aimed to further determine the impact of CCR5 variants (CCR5-Δ32 and CCR5- R223Q) on HIV susceptibility, viral load suppression and CD4 recovery during highly active antiretroviral therapy (HAART) among Malaysian HIV patients. Methods: This cross-sectional study involved 182 HIV-infected who were recruited from three out-patient clinics, and 150 non-HIV subjects from Malay, Chinese and Indian ethnicities. CD4 count and viral load data at 4-6 months (t1) and 8-12 months (t2) after starting HAART were gathered from hospital records. Chi-square test was used to analyse the correlation between CCR5 variants with dependent variables. Results: Heterozygous CCR5-Δ32 and CCR5-R223Q occurred in a percentage of 0.5% (1/182) and 1.7% (3/182) among HIV patients respectively, while none of homozygous mutant for CCR5-Δ32 and CCR5-R223Q were found. CCR5-R223Q was found more frequently in non-HIV as compared to the HIV group (P=0.018). However, both polymorphisms were not found to be correlated with CD4 recovery to ≥500 cells/mm3 (P>0.05) and viral load suppression ≤50 copies/mL (P>0.05). Conclusion: CCR5-R223Q and CCR5-Δ32 alleles probably have no modifying effects on HIV susceptibility virological and immunological recoveries in the first 12 months of HAART, partially due to the low prevalence of these mutations in the studied population.
