A 30 year old male presented with insidious onset of painless swellings in tendons over 20 years, with learning difficulty, tremors, progressive instability of gait and frequent falls. There was no similar illness in family. On examination, there was firm, non tender, nodular swelling Achilles, patellar and tricep tendon, clubbing of fingers. The Mini Mental Status Examination score was 16/30. Plantar response was extensor. There was cerebellar signs with nystagmus, truncal titubation, ataxic gait and intentional tremors. Cranial MRI showed bilateral hyperintensities in dentate nucleus, globus pallidus, periventricular white matter on FLAIR/T2 sequences, and diffuse cerebral and cerebellar atrophy. The patient was diagnosed as having cerebrotendinous xanthomatosis based on the clinical and radiological features. As cerebrotendinous xanthomatosis benefit from therapy and progress of the disease is preventable, the case illustrates the need for early diagnosis.

Aims: Camellia sinensis ( green t ea) is known for its therapeutic properties (anti - inflammatory, anti - oxidative and anti - ageing). The aim of this study was to determine the in vitro inhibitory activity of gree n tea extract on some odorous skin commensal bacteria. Methodology and results: Tea leaves were collected from MARDI Agro Technology Park, Cameron Highlands. A standardised protocol was used to obtain green tea extract. Aqueous green tea extracts were tes ted for antibacterial activity by well diffusion method. Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) assays were performed by broth microdilution assays using green tea extract concen trations from 16 to 0.0313 mg/ mL . Green tea extract showed antibacterial activity against skin microbiota. The high antimicrobial effect was achieved against Micrococcus luteus with MIC and MBC of 0.125 and 0.25 mg/μL respectively, followed by Staphylococcus epidermidis with MIC and MBC o f 0.25 and 0.25 mg/μL respectively, Bacillus subtilis with MIC and MBC of 0.5 and 0.5 mg/μL respectively and lastly, Corynebacterium xerosis with MIC and MBC of 0.5 and 1.0 mg/μL respectively. Conclusion, significance and impact of study: The results obta ined from the study confirm the in vitro anti - microbial activity of green tea extracts against skin microbiota. The antibacterial effects of green tea against skin bacteria with its anti - oxidant and anti - aging properties will help in keeping skin healthy, fresh and reducing unpleasant odo rs .
Camellia sinensis

Diarrhoea is a leading killer of children, accounting for 9% of all deaths among children under age 5 worldwide and 3% in Malaysia in 2015. A large proportion of diarrhoea illnesses among children in developing countries are ascribed to an unknown etiology because microscopic examination was the only available technique which has low detection limits. The proposed study aimed to evaluate a new quadriplex PCR assay to detect parasitic pathogens namely E. histolytica, G. lamblia and C. parvum which considered responsible for the majority of human infections. Three set of specific primer pairs were designed for detection of parasitic pathogens. Quadriplex PCR assay was optimized and an internal amplification control was incorporated to check for PCR inhibitors in samples. The PCR assay was evaluated using spiked stool samples. Specific primer pairs were successfully designed and simultaneously amplified the targeted genes. The analytical sensitivity of the quadriplex PCR at the DNA level was found to be 50 ng DNA. The analytical specificity was evaluated with 11 reference protozoal and bacterial strains and was found to be 100%. We concluded that the developed quadriplex PCR assay was rapid and gave results within 5 hours which is essential for the identification of parasitic pathogen and might be useful as an additional diagnostic tool whenever time is important in the diagnosis of parasite that cause diarrhoea.
