Background: Classification of symptomatic dengue according to current World Health Organization (WHO) criteria is not straightforward. In this prospective study of dengue infection during an epidemic in India in 2004, we applied the WHO classification of dengue to assess its usefulness for our patients. Methodology: The study included 145 clinically suspected cases of dengue infection of all ages. Dengue was confirmed by serological methods (IgM ELISA and HI test). WHO criteria were applied to classify dengue positive patients into Dengue Fever (DF), Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Clinical and laboratory parameters were compared between dengue patients with bleeding and those without bleeding. Results: Out of the 50 serologically positive cases of dengue enrolled in the study, only 3 met the WHO criteria for DHF and 1 met the criteria for DSS; however, 21 (42%) cases had one or more bleeding manifestations. Conclusion: By using WHO criteria of DHF on Indian patients, all severe cases of dengue cannot be correctly classified. A new definition of DHF that considers geographic and age-related variations in laboratory and clinical parameters is urgently required.

A brief description is given of the efforts of the World Health Organization to facilitate international communication and comparability of data in oncology by developing uniform classifications and nomenclatures for the microscopic definition of tumours. This has involved the collaboration of over 200 pathologists in 46 countries, in a network of 19 International Reference Centres. Ten of these Centres have already completed their work. Reports have begun to appear in the literature of studies based on the classifications they have prepared.

AbstractIraq currently undergoing the problem of water shortage, although Iraq has two Rivers (Euphrates and Tigris) pass throughout most of its areas, and they have represented a major source of water supply. In the current research, to evaluate the quality of the Euphrates river in Iraq based on the values of total dissolved salts (TDS), the TDS concentrations were collected from sixteen sections along the river in the three succeeding years (2011, 2012, and 2013). The evaluation of the river was done depending on the classification of (W.H.O. (World Health Organization). (2003). Total Dissolved Salts in Drinking-water: Background document for development of W.H.O. Guidelines for Drinking-water Quality. World Health Organization, 20 Avenue Appia, 1211 Geneva 27, Switzerland). of rivers for drinking uses. Inverse Distance Weighting Technique (IDWT) as a tool in the GIS was employed to establish the maps of the river that using interpolation/prediction for the TDS concentrations to each selected year and the average values of TDS for these 3 years. Based on the five categories of rivers’ classification of the TDS concentrations according to the (W.H.O. (World Health Organization). (2003). Total Dissolved Salts in Drinking-water: Background document for development of W.H.O. Guidelines for Drinking-water Quality. World Health Organization, 20 Avenue Appia, 1211 Geneva 27, Switzerland), the Euphrates river was classified, and the maps of classification for the years 2011, 2012 and 2013 and the average values for 3 years were created. The average values for 3 years of TDS along the Euphrates river indicated that the sections from SC-1 to SC-4 as moderate-water-quality-Category-3, the sections from SC-5 to SC-10 as poor-water-quality-Category-4, while the sections between SC-11 to SC-16 as very poor-water-quality-Category-5. The interpolation maps showed that the Euphrates river in Iraq was ranged from moderate water quality (Category-3) to very poor water quality (Category-5).
