AIMS/BACKGROUND Recently a commercially available scanning laser Doppler flowmeter has been produced, which provides two dimensional maps of the retinal perfusion. The aim of the present study was to investigate the reproducibility and the sensitivity of these measurements. METHODS 16 healthy subjects were randomised to inhale different gas mixtures of oxygen and nitrogen in a double blind cr...

introduction: some studies have suggested correlation between mpv index and inflammatory diseases such as rheumatoid arthritis in adults. though bronchopulmonary dysplasia is also an inflammatory disease which develops in preterm neonates with respiratory distress syndrome, we decided to study the possible correlation between the mean platelet volume (mpv) and the occurrence of bronchopulmonary...

The chief complaint of many patients with chronic obstructive pulmonary disease (COPD) is that they are no longer able to carry out or maintain an activity of which they were previously capable [1, 2]. The mechanism of activity limitation is now felt to be multifactorial, related to muscle dysfunction as well as to pulmonary factors. A key concept is that activity limitation (or exercise intole...

BACKGROUND Idiopathic stabbing headache, which is a brief, sharp, severe jabbing pain that is confined to the head, responds well to treatment with indomethacin sodium. It may occur as a primary entity but more likely is associated with other types of headache, including migraine. SETTING Emergency department of a teaching hospital. PATIENT A 27-year-old man presented to the emergency depar...

Background: Occupational noise-induced hearing loss (ONIHL) is a hearing disorder that affects workers all over the world. Preconditioning with several mild or less potent stressors will effectively prevent the development of noise-induced hearing loss. This study investigated the possible preventive effects of normobaric hyperoxia preconditioning on preventing the noise-induced hearing impairm...

Despite providing symptomatic relief in patients with congestive heart failure (CHF), supplemental oxygen (O(2)) has been demonstrated to increase total peripheral resistance. The present study investigated the possibility that O(2) inhalation reduces nitric oxide (NO) bioavailability, using endothelium-dependent (acetylcholine) and -independent (phentolamine) vasodilators, and the antioxidant ...
