[A statistical approach to pruritus senilis].
The purpose of this study is to analyse the cause of itching and explore the relationships between pruritus senilis and various stimuli. Sample of 132 men and 238 women with ages ranging from 60 to 96 years were used in our study. Pruritus senilis is not significantly related to cosmetics and soap. Nevertheless, statistically significant correlations were found between pruritus senilis and physical stimuli (e. g., warmth, coldness, dryness). These observations could suggest that pruritus senilis is caused by changes of temperature.
