The accumulation of tear film proteins as well as microbes colonization onto worn contact lenses can be eliminated conventionally by mechanical rubbing during the cleaning process. Lens2® functions in rotation manner to loosen the deposits on the contact lens and has antimicrobial coating to keep lenses away from contamination. The objective of this study was to determine the efficiency of Lens2® to remove deposited protein and reduce microbial contamination compared to conventional method. Twenty-eight subjects each wore a pair of contact lens FDA Group 1 (Polymacon, SoftLens®38, Bausch & Lomb) for one month and cleaned them using multipurpose solution (COMPLETE® MoisturePLUSTM, Advanced Medical Optics) separately using two different methods. The right lens was cleaned conventionally while the left lens were cleaned using the Lens2®. The control group of thirteen subjects each wore a pair of contact lens for the same period and cleaned both conventionally. These lenses and its cases were then analyzed for protein deposition using Bichinchoninic Acid Assay (BCA) Kit (Sigma, USA) in 96-well plate. Microbial contamination was determined by culturing the samples on nutrient agar for bacteria and fungi and non-nutrient agar for amoeba isolation. The mean of total protein on control lenses (17.014 ± 13.246 μg/mL) was not significantly different from those on the Lens2® (21.623 ± 19.127 μg/mL). There were also low growth numbers of amoeba in each group of samples. Interestingly, there were no growths of amoeba from all Lens2® samples collected. There was also low growth numbers of bacteria in each sample group whereby Lens2® had the lowest growth of bacteria. No growth of fungi was obtained from all samples. The automatic lens cleaner, Lens2® was found to be as efficient as the conventional cleaning method. However, the Lens2® has additional advantage because of its antimicrobial material and need shorter time in the cleaning process as well as easy and effective.

The detection rate of thyroid incidentalomas is increasing; in fact, as many as 2.3% of patients undergoing FDG PET-CT for other indications have been found to have thyroid incidentalomas. The risk of malignancy in these thyroid incidentalomas can be as high as 47%. The increased uptake and the focal uptake pattern of F-18 fluorodeoxyglucose (FDG) in the thyroid during positron emission tomography (PET)-computed tomography (CT), and the calcification of the thyroid incidentaloma, are associated with even higher risk of malignancy. We report a case of a lady undergoing FDG PET-CT for breast cancer staging but noted to have a calcified thyroid incidentaloma, which was proven to be follicular thyroid carcinoma.

Introduction: Child malnutrition continues to be a major public health problem in developing countries. This study aims to determine the current nutritional status of Malaysian school children using the anthropometric indicators of weight for age (WAZ), height for age (HAZ), and body mass index for age (BAZ). Methods: A nationwide school-based survey was undertaken in all Malaysian states and territories, which included 18,078 children aged 8-10 years attending 445 primary schools. The software WHO AnthroPlus was used to calculate zscores for the nutritional status (WAZ, HAZ and BAZ) of the target population relative to the World Health Organization (WHO) 2007 reference. Results: The national prevalence of underweight among school children was 13.6% and in rural areas, this rate was nearly double that of urban areas. The national prevalence rate for stunting was 10.9%, double among rural school children compared to their urban counterparts. As for thinness, the national prevalence was 6.5%. Using the WAZ indicator, we found that the national prevalence of overweight children was 7.6%. Additionally, we found that urban areas showed a higher prevalence of overweight children (8.8%) than rural areas (5.9%). Conclusion: The findings of this study indicate that Malaysian school children face the burden of malnutrition, suffering from both undernourishment and overweight. Malaysia must make a concerted effort to overcome the problems of malnutrition among children.

Cronkhite-Canada Syndrome (CCS) is a syndrome characterised by a constellation of signs including but not limited to onychodystrophy of the finger and toe nails, skin hyperpigmentation and alopecia. Endoscopic features showed hamartomatous polyps involving all segments of the gastrointestinal tract with the characteristic exception of being oesophageal sparring. These polyps show confirmation by the presence of eosinophils and mast cells at the lamina propria upon histological studies.

Objectives: Diabetes mellitus is associated with a greater likelihood of developing certain oral mucosal disorders. This study was aimed at assessing the prevalence of oral mucosal lesions (OMLs) in patients with type 2 diabetes (DM2) and to investigate the association of such lesions with metabolic control of the disease. Methods: This cross-sectional study involved 391 patients with DM2 and 391 non-diabetic control subjects. Demographic information and data on the duration and type of diabetes, glycosylated hemoglobin (HbA1c) values, medical history, and current use of medication were obtained from medical records. Detailed oral examination was performed in accordance with international criteria. Results: The prevalence of OMLs was significantly higher among diabetic patients (45.5%) than among control subjects (38.4%) (P = 0.042). Patients with diabetes had a higher prevalence of geographic tongue (GT) (P = 0.017), denture stomatitis (P = 0.018), and angular cheilitis (P = 0.006) than controls. Overall, diabetic patients with poor metabolic control had a significantly higher prevalence of OMLs and xerostomia than patients with moderately and well-controlled disease (P < 0.05). Conclusions: The prevalence of OMLs was significantly higher in diabetic patients than in control subjects. Higher occurrence of OMLs was significantly associated with poor metabolic control.

Introduction: Chronic Respiratory Questionnaire (CRQ) is one of the disease-specific questionnaires to assess health related quality of life (HRQoL) among chronic obstructive pulmonary disease (COPD) patients. Objectives: This study investigate the validity and reliability of Malay version CRQ among COPD patients. Methods: The CRQ was administered twice to 46 patients with COPD (mean FEV1 44% predicted, FEV1/ IVC 37% predicted) from Medical Center of University Kebangsaan Malaysia (PPUKM).Test-retest reliability was assessed using intra-class correlation coefficients (ICC). Internal consistency was determined using Crohnbach’s alpha coefficients (α = 0.7). Spearman’s correlation coefficient was done among the scores of CRQ, St George Respiratory Questionnaire (SGRQ) and sixminute walking test (6MWT) to examine the concurrent validity of the CRQ (p<0.05). Results: High internal consistency (α > 0.70) was observed for 3 domains of CRQ with exception of dyspnoea domain (α = -0.631). Test retest reliability demonstrated strong correlation (ICC >0.80). Concurrent validity of CRQ, showed significant correlations observed between domain of SGRQ’s symptom, impact and total scores of SGRQ with CRQ’s dyspnoea and emotional function (-0.3< r < -0.4; p<0.05). Significant correlation was observed between 6MWT and CRQ’s fatigue domain (r= 0.390; p=0.007). Conclusions: The Malay version of CRQ is a reliable instrument for measuring health status of patients among chronic respiratory disease especially COPD. Items of fatigue, emotion, and mastery domain of the CRQ are reliable and valid and can be used to assess quality of life in patients with severe airways obstruction. Items of the dyspnoea dimension are less reliable and should not be included in the overall score of the CRQ in comparative research.

Background: This study aims to examine various solvent extracts of Cyphomandra betacea (tamarillo) also known as the tree tomato, for their bioactive constituents and antioxidant activity. The study also aims to examine its effect on cancer cell death using two types of cancer cell lines (liver and breast cancer cell). Methods: The first part of the study evaluates the nutritional composition of tamarillo. Then, phytochemical profiling using GC-MS analysis in ethanolic tamarillo extract was conducted. Different fractions of n-butanol, ethyl acetate and aqueous fractions were obtained from the ethanolic extract of tamarillo. Then, the fractions were subjected to the quantification of total phenol (TPC) and flavonoid contents (TFC), free radical scavenging activity (SA) and also antioxidant activity (AOX) assayed by beta-carotene bleaching (BCB) assay. Finally, the capability of the ethanolic extract of tamarillo and different fractions were evaluated for their anticancer properties. Results: Findings from this study revealed that the nutritional composition (ash, protein, carbohydrate and total dietary fiber), and mineral levels (calcium, magnesium, potassium and iron) of tamarillo were moderate. The crude ethanol extract of tamarillo contained the highest phenolic and total flavonoid content. FT-IR analysis revealed the presence of alkanes, carboxylic acid, phenol, alkanes, carboxylic acids, aromatics and nitro compounds. Twelve bioactive constituents in tamarillo have been identified through GC-MS analysis. Cytotoxic activity suggests the potential of ethanolic extracts of tamarillo having a chemopreventive effect on breast and liver cancer cells. Conclusion: This study reveals that tamarillo has substantial antioxidant activity as well as anticancer properties.

Background: Positron Emission Tomography and Computed Tomography (PET-CT) imaging is shown to influence a decision change in managing non-small cell lung carcinoma (NSCLC). The introduction of such a facility in Malaysia is relatively recent, and its impact from its utility is currently being assessed. Aim: In a tertiary referral centre possessing the only PET-CT facility in northern Peninsular Malaysia, we evaluated the potential roles of PET-CT in referred patients with non-small cell lung carcinoma. Methodology: Sixty eligible adult cases with NSCLC, between September 2005 and December 2007, were retrospectively reviewed. Relevant data was collected using standard questionnaire for indications, staging of disease, and outcomes in terms of recurrence and response to prescribed cancer-specific therapy. Results: The indications for PET-CT were: staging of a newly diagnosed non-small cell lung carcinoma (25.0%); post-operative restaging (21.7%); exclusion of recurrence or metastasis (18.3%); establishing diagnosis of carcinoma (13.3%); assessment of response to treatment (11.7%), and for surveillance (10.0%). The use of PET-CT was shown to induce a change in the staging, compared with non-PET conventional means in 69.2% of patients with newly diagnosed lung carcinoma (upstaged in 55.5%; downstaged in 44.5%) and in 65.0% of patients who underwent cancer-specific treatments (upstaged in 38.5%; downstaged in 61.5%). PET-CT detected recurrence in 62.5% who underwent the imaging to exclude a recurrence or metastasis. Conclusion: PET-CT has affected the staging of a large proportion of our local Malaysian patients. Like elsewhere, the availability of such a facility is likely to have important influence in overall management of NSCLC in Malaysia.

Percutaneous Endoscopic Gastrostomy (PEG) tubes were often offered to patients requiring long term enteral feeding. Even though the procedure is relatively safe, it is associated with various complications such as peritonitis or even death. 1 We presented a case of a 54-year-old gentleman with underlying ischemic stroke and pus discharges from a recently inserted PEG tube. Computed Topography (CT) scan confirmed abdominal wall necrotising fasciitis complicated with hyperosmolar hyperglycaemia state (HHS) and later succumbed after 48 hours of admission. Our case illustrated the rare complication related to the insertion of PEG tube; abdominal wall necrotising fasciitis that was associated with mortality.
