Health profile of the ageing population: the Swedish experience.

Sweden is demographically one of the oldest countries in the world. The average life expectancy is comparatively high. However, the total number of physical and mental disorders, which may affect the elderly, seems to be increasing and becoming more and more complicated to prevent and treat.

Quantification of burn induced extravasation of Evans blue albumin based on digital image analysis.

The present study evaluated a non-invasive method based on digital image colour analysis that allows near-continuous quantification of extravasated Evans blue albumin after burn injury. A full-thickness burn was induced in the abdominal skin of rats, followed by injection of Evans blue dye. Tissue content of Evans blue were quantified using spectrophotometry, and compared with digital colour analysis.

[Supplementary insurance: yes or no? An investigation into the motives of patients].

Of the group of dentate adults taking part in the Public Health insurance scheme, 78% has opted for a supplementary insurance for dental care after the dental health care reform on January 1, 1995. For edentulous people this figure is 33%. Both for people who choose for a supplementary insurance and for those who did not, financial motives were most important.

Studies on human minor salivary gland secretions using the Periotron method.

Secretions from minor salivary glands were estimated in 127 individuals by the Periotron method of measuring fluid output from different mucosal sites, and outputs were related to different variables. Large intra- and interindividual variations in secretions (expressed as microliter/cm2 per min) were observed, with means of 0.9 for the palatal, 4.

Use of computer-assisted image analysis for noninvasive evaluation of oral lichenoid reactions and oral leukoplakia.

The objective of the present study was to elaborate and to evaluate a method in which the clinical appearance of a mucosal lesion could be expressed by means of color and morphologic features extracted from digitized images. The ability to express mucosal changes with image features was evaluated, as was the accuracy of a classification of the lesions on the basis of image feature analysis. Computer-assisted image analysis was performed on digitized color slides from 76 patients with lichenoid reactions that included both oral lichen planus and contact lesions and 20 patients with homogenous oral leukoplakia.
