Measurements of the viscosity of blood serum reported by clinical observers have in many cases shown results that are seemingly paradoxical, as for example a small effect of high dilution on serum viscosity in nephrosis; a low serum viscosity in pernicious anemia, and a high one in icterus, though they are both characterized by a high bilirubin content of the blood; a low serum viscosity in man...

OBJECTIVES Barrett oesophagus is replacement of squamous epithelium to specialised intestinal metaplasia. It is associated with an increased risk for adenocarcinoma which develops through dysplasia. The aim of this retrospective study was to determine the relative age of occurrence and incidence of dysplasia in this part of our country. METHODS Between January 1999 and June 2002 we diagnosed ...

The testicular changes in pneumonia are without clinical manifestations, are non-specific, focal in character, independent of the infecting organisms or the antecedent disease, and vary in severity directly with the total length of the illness. The process is a continuous one, divisible into stages in which the following features are recognizable: (1) cessation of spermatogenesis; (2) degenerat...

Over the last two decades, age-related anatomical and functional brain changes have been characterized by evidence acquired primarily by means of non-invasive functional neuroimaging. These functional changes are believed to favor positive reorganization driven by adaptations to system changes as compensation for cognitive decline. These functional modifications have been linked to residual bra...

OBJECTIVE The aim of this study was to identify the prevalence of pathological changes in the pericoronal tissue of asymptomatic impacted lower third molars and to assess the correlation between pathological changes and patient demographic, radiographic and morphological characteristics. STUDY DESIGN Follicles associated with fully impacted lower third molars were submitted for histological e...

background: the internet addiction, also described as pathological internet use (piu), is conceptualized by an individual's in­ability to control his or her use of the internet, which eventually causes marked distress and/or functional impairment. the aim of the present study was to investigate the prevalence of the piu among adolescence, in relation to different internet ac­tivities, and to ex...
