Homozygosity of ACE gene deletion polymorphism is a risk factor for white matter lesions when it is associated with cerebral infarction. This suggests that it may be possible to identify subjects who are at greater risk of developing white matter lesions and are at risk of cognitive impairment and possibly dementia.
Sampling from the prostatic TZ by directed needle biopsies at repeated SPB was associated with a very low incidence of PCa (2.5%), especially if compared to TURP (19% detection rate), and could be omitted.
