ner. Furthermore, IL-10 and TGF-β1 showed a synergic effect. Conclusion IL-10 and TGF-β1, the cytokines of regulatory T cells, suppress the formation and bone resorption function of the osteoclasts.

The dual energy CT (DECT) technology has been recently employed in the form of two X-ray sources of different energies to enhance the contrast between adjacent structures. Its use in the cardiac arena has been widely highlighted due to the higher temporal resolution. However, it may also be used in the craniocervical and peripheral vasculature for better differentiation between contrast-enhanced vascular lumina and calcified plaques, in the characterisation of ureteric stones, and in the evaluation of hepatic lesions. The objective of this paper is to revisit DECT physics, review the literature and discuss its use in CT neuroangiography with case illustrations from our institution, and impact on dose savings.

7.In vitro activities of antifungal drugs against yeasts isolated from blood cultures and moulds isolated from various clinically significant sites in Singapore.
Annals of the Academy of Medicine, Singapore 2008;37(10):841-846
INTRODUCTIONFungaemia carries with it high mortality rates and appropriate as well as timely antifungal therapy has been shown to be life saving.
MATERIALS AND METHODSWe studied the invitro activities of antifungal agents using the Etest method, against 100 Candida isolates from blood cultures, 10 Cryptococcus isolates from blood or cerebrospinal fluid and 50 mould isolates from various clinically significant sites of patients in Singapore General Hospital, from June 2004 to December 2006.
RESULTSOverall, the yeasts appeared to have low minimum inhibitory concentrations (MICs) for all the 5 antifungal drugs tested except for fluconazole. The overall high MIC90 values of the moulds against the azoles were largely attributed to the non-Aspergillus moulds. Posaconazole, itraconazole, voriconazole and caspofungin appear effective against local strains of Aspergillus species, although there are no interpretive breakpoints.
CONCLUSIONSThe results show that the local fungal strains studied appear to be susceptible to the usual antifungal drugs recommended in the literature.

The shoulder and axillary regions contain various complex anatomical structures in close proximity, many of which can give rise to neoplasms. Determining the origin and hence the exact diagnosis of advanced (diffuse) tumours in this region may become problematic. In view of the tumour morphology and the affected location in this case, we highlight the importance of Hodgkin lymphoma immunohistochemistry interpretation in a tumour which was initially suspected to be a soft tissue sarcoma.
9.Importance of data management with statistical analysis set division.

Testing of hypothesis was affected by statistical analysis set division which was an important data management work before data base lock-in. Objective division of statistical analysis set under blinding was the guarantee of scientific trial conclusion. All the subjects having accepted at least once trial treatment after randomization should be concluded in safety set. Full analysis set should be close to the intention-to-treat as far as possible. Per protocol set division was the most difficult to control in blinded examination because of more subjectivity than the other two. The objectivity of statistical analysis set division must be guaranteed by the accurate raw data, the comprehensive data check and the scientific discussion, all of which were the strict requirement of data management. Proper division of statistical analysis set objectively and scientifically is an important approach to improve the data management quality.

10.Prevention and handling of missing data in clinical trials.

Missing data is a common but unavoidable issue in clinical trials. It not only lowers the trial power, but brings the bias to the trial results. Therefore, on one hand, the missing data handling methods are employed in data analysis. On the other hand, it is vital to prevent the missing data in the trials. Prevention of missing data should take the first place. From the perspective of data, firstly, some measures should be taken at the stages of protocol design, data collection and data check to enhance the patients' compliance and reduce the unnecessary missing data. Secondly, the causes of confirmed missing data in the trials should be notified and recorded in detail, which are very important to determine the mechanism of missing data and choose the suitable missing data handling methods, e.g., last observation carried forward (LOCF); multiple imputation (MI); mixed-effect model repeated measure (MMRM), etc.
