[Knowledge about PSA among primary care physicians].

Objective: The use of prostate-specific antigen as a tumor marker has led to an important advancement in the diagnosis of prostate cancer. Primary care physicians have started to request this test over the last 5 or 6 years. However, an inadequate use of this tumor marker has been observed.

Oral surgery in patients undergoing oral anticoagulant therapy.

Unlabelled: There is an evident need for procedural protocol for oral surgery patients who undergo oral anticoagulant treatment (OAT) because of: 1) the possible severity of complications and 2) the growing demand for OAT, which in some cases may be as much as 8% of the oral surgery patients that are referred to the hospital from primary care centers. In this study, the authors define the parameters for creating a proto- col applicable to this group of patients. The conclusion is that it is not necessary to suspend OAT before surgery; rather, these procedures should be performed under multidisciplinary medical control.
