Volumetric analysis of the terminal ductal lobular unit architecture and cell phenotypes in the human breast.

The major lactiferous ducts of the human breast branch out and end at terminal ductal lobular units (TDLUs). Despite their functional and clinical importance, the three-dimensional (3D) architecture of TDLUs has remained undetermined. Our quantitative and volumetric imaging of healthy human breast tissue demonstrates that highly branched TDLUs, which exhibit increased proliferation, are uncommon in the resting tissue regardless of donor age, parity, or hormonal contraception.

Missed Injuries in Polytrauma Patients after Trauma Tertiary Survey in Trauma Intensive Care Unit.

Background And Aims: Injuries are often missed during the primary and secondary surveys in trauma patients. Studies have suggested that a formal tertiary survey protocol lowers the number of missed injuries. Our aim was to determine the number, severity, and consequences of injuries missed by a non-formalized trauma tertiary survey, but detected within 3 months from the date of injury in trauma patients admitted to a trauma intensive care unit.
