title: Early birth order in Briquet's syndrome.
abstract: Birth order in 90 female patients with Briquet's syndrome was significantly earlier than the theoretical mean for a normally distributed population. In contrast, the birth order of 78 women with primary alcoholism did not differ from this mean. These results suggest an early environmental influence in the development of Briquet's syndrome in women.
