Assessment of depression in Alzheimer's disease: symptoms, syndrome, and computed tomography findings.

The Hamilton Rating Scale for Depression (HAM-D) and DSM-III-R criteria were simultaneously employed to assess the prevalence of depression in 26 outpatients with dementia of the Alzheimer type and 26 age-matched normal control subjects. Both assessment methods evidenced a higher frequency of depression during the severe stages of Alzheimer's disease. Among the Alzheimer patients, the prevalence rate of depression produced by the HAM-D (38%) was higher than the rate produced by DSM-III-R criteria (23%).

A modified bladder washout test to improve diagnostic results in chronic urinary tract infections.

Bladder washout (BWO) and antibody-coated bacteria (ACB) tests were performed on 25 patients with radiological and/or clinical evidence of chronic upper urinary tract infection (UTI) and 12 patients with asymptomatic bacteriuria. Using a traditional single-washout procedure, the BWO test gave equivocal results in many cases of chronic pyelonephritis; this seemed mainly due to the lack of complete bladder sterilization. A modified procedure, including double sterilization and irrigation, biochemical typing of isolated bacteria, and evaluation of temporal pattern of bacteriuria recurrence, was then introduced.
