Safety, clinical outcome, and fracture rate of femoropopliteal stenting using a 4F compatible delivery system.

Objective: To determine the safety, clinical outcome, and fracture rate of femoropopliteal interventions using 4F stents.

Methods: Between January 2010 and December 2011, 112 symptomatic patients were treated by stent implantation. Ten patients were lost to follow up; therefore, 102 patients (62 men; mean age 66.

The effect of age and body size on the urinary excretion of C-peptide from birth to 14 years of age.

The daily excretion of C-peptide in the urine was measured in 105 healthy infants and children from birth to 14 years of age. For technical reasons no studies were performed from 1-3 years of age. The excretion of C-peptide showed a close positive correlation with age and weight.
