[Gastrointestinal amyloidosis in a patient with multiple myeloma].

Background: Gastrointestinal amyloidosis is characterized by deposition of amyloid in the gastrointestinal mucosa. This can cause an increased risk of malabsorption, obstruction, gastrointestinal bleeding and perforations.

Case Description: A 52-year-old male presented with rectal bleeding.

Increased carotid and femoral intima-media thickness in patients after repair of aortic coarctation: influence of early repair.

Background: In patients, after repair of aortic coarctation, abnormal function of the proximal precoarctation arterial conduits has been demonstrated, but data on arterial wall structure of proximal and distal arteries in patients are scarce. The aim of our study is to compare intima-media thickness (IMT) of the carotid and femoral arteries in controls and patients after coarctation repair and to identify independent predictors of carotid and femoral IMT.

Methods: A total of 137 patients after repair of aortic coarctation (89 male, median age 29.
