- The regional cerebral blood flow, brain atrophy, white matter changes and neurophysiologic changes were evaluated in 28 patients with a clinical diagnosis of probable Alzheimer''s disease (AD) and in 8 patients with a clinical diagnosis of frontal lobe dementia (FLD) using single photon emission computed tomography, magnetic resonance imaging and electroencephalography (EEG). We found that FLD patients had more severe frontal blood flow reduction and less severe parietal blood flow reduction compared to AD patients. Among patients with mild dementia the EEG changes were less severe in the FLD group. No significant differences were found in white matter changes or in regional atrophy.

- Purpose: The purpose of this study was to evaluate air enema as a method of assessing acute colitis. Material and Methods: Twenty-seven patients with symptoms of acute colitis underwent plain abdominal radiography, air enema, and colonoscopy within 48 h. The films were evaluated by 3 observers with different levels of experience, both independently and together, and the results were then compared to the findings at endoscopy. Results: Air enema visualized a greater part of the colon than plain abdominal radiography. When air enema was compared to endoscopy as the reference, it showed good correlation, with a positive predictive value of 92% (sensitivity 62%, specificity 85%). Evaluation of the rectum was less accurate, a finding that emphasized the importance of rigid sigmoidoscopy. Conclusion: Air enema is a useful diagnostic method in acute colitis, it is easily performed and tolerated well with no observed complications. It is also easy to interpret, as shown by a high level of agreement (k=0.67) among the 3 independent observers with very different levels of experience.
