Background: The problem of image quality in a large number of upper airway obstructed patients is the superimposition of the airway over the bone of the spine on the AP view. This problem was resolved by increasing KVp to high KVp technique and adding extra radiographic filters (copper filter) to reduce the sharpness of the bone and increase the clarity of the airway. However, this raises a concern that patients might be receiving an unnecessarily higher dose of radiation, as well as the effectiveness of the invented filter compared to the traditional filter.

Background: Although plasma leakage is the major cause of mortality and morbidity in patients with dengue hemorrhagic fever (DHF), a detailed assessment of the natural course of this process is still lacking. We employed serial ultrasound examination to delineate the locations and the timing of plasma leakage and to evaluate the usefulness of ultrasound in detecting plasma leakage in DHF.

Method: Daily ultrasound examinations of the abdomen and right thorax were performed in 158 suspected dengue cases to detect ascites, thickened gall bladder wall and pleural effusions.
