Studies show that the pH of the malaria parasite’s digestive vacuole (DV) plays a key role in the physiological functions of this organelle and antimalarial drug accumulation, and yet is technically difficult to measure. In this study, a flow cytometry-based technique was developed to measure the DV pH using a ratiometric pH indicator, FITC-dextran loaded into the DV of saponin-permeabilized parasites. To calculate the DV pH, a standard pH calibration curve was generated by incubating the saponin-permeabilized cells in buffers with different pH in the presence of an ionophore, CCCP. The measured average pH of the DV was 5.27 ± 0.03 that is approximately the same in the parasites observed microscopically by Hayward et al. (2006) (5.50 ± 0.14) using the same probe. The removal of glucose from the medium, causing a rapid depletion of parasite ATP, resulted in an alkalization of the DV. The DV was reacidified upon restoration of glucose to the medium. This technique provides a rapid, simple and quantitative measurement of the DV pH on a large number of cells. It will also be useful in future attempts to evaluate the effect of antimalarial drugs (i.e. chloroquineand artemisinin-based drugs) in pH changes of the DV.

Osteo-odontokeratoprosthesis (OOKP) surgery is a technique used to replace damaged cornea in blind patients for whom cadaveric transplantation is not feasible. OOKP surgery is a complex procedure requiring lifetime follow–up. The preservation of the osteo–odontolamina is the vital feature in maintaining the stability of the OOKP. Early detection of lamina resorption enables early prophylactic measures to be taken and prevent resorption-related complications. This case illustrates the radiological findings of the first OOKP surgery in Malaysia and the role of multidetector computed tomography (MDCT) in postoperative management of OOKP surgery.

OBJECTIVE: 1.To evaluates and recognizes findings in chest radiograph in patients with laboratory-confirmed S-OIV (H1N1) infection treated at UKMMC. 2. To evaluate whether the findings on initial chest radiographs of influenza A (H1N1) patients can help to predict the prognosis. MATERIAL AND METHODS: Total of 109 adult patients presenting to the Universiti Kebangsaan Malaysia Medical Centre (UKMMC) with flu-like symptoms who were positive for influenza A and these patients had underwent chest radiographs (CXR). The initial CXRs were evaluated for the pattern (consolidation, ground-glass, and reticulation), distribution, and extend of abnormality. The disease is classifies by the clinical severity (mild, moderate or severe illness) and adverse outcome (ventilated, death or recovered well). RESULTS: The initial CXRs were normal in 56% of cases. The predominant radiographic finding was consolidation, most commonly involving the middle and lower zones (35% of cases). There is no significant association between initial CXR findings with the patient clinical outcome either fully recovered or death/ ventilated. CONCLUSION: Normal chest radiographs is the most common radiographic finding in S-OIV (H1N1) infection and the most common abnormal lung finding is consolidation. Initial chest radiographs did not determine the patient clinical outcome and a normal initial radiograph could not exclude adverse outcome.

Food is closely related with emotion. It often provides comfort and satisfaction. Some individuals choose to turn to food to curb their negative emotion, resulting in disturbances in eating patterns, such as overeating which lead to obesity and severely controlling food intake, which culminate in eating disorders like anorexia nervosa, bulimia nervosa and binge eating. These disorders are not related to the eating problems per se but often due to underlying or complicated by psychological factors, namely depression, anxiety, impulse control problems and personality. The roles of psychological factors in eating disorders and obesity should therefore not be downplayed. These disorders should be managed comprehensively involving multiple approaches, including not only biological but also psychological interventions provided by a professional team comprising endocrinologists, psychiatrists, dietitians, exercise physicians and surgeons.
