1.  Contrast-induced acute kidney injury following iodine opacification other than by intravascular injection 
Clinical Kidney Journal  2012;5(5):456-458.
Contrast-induced acute kidney injury (CI-AKI) classically occurs following the intravascular administration of iodinated contrast medium (CM). However, some cases of iodine-induced nephrotoxicity have been reported in patients who did not receive intravascular CM, as a consequence of iodine absorption through mucosae, burned skin or interstitial tissues. Recently, we observed the first case of CI-AKI occurring after an enteroclysis without any direct intravascular injection of CM. Here, we report this case, and review other clinical situations in which renal toxicity has been reported following the non-intravascular use of iodinated compounds.

2.  Aorto-venous fistula between an abdominal aortic aneurysm and an aberrant renal vein: a case report 
Introduction
The potential complications of an abdominal aortic aneurysm include rupture, compression of surrounding structures, thrombo-embolic events and fistula. The most common site of arterio-venous fistula is the inferior vena cava. Fistula involving a renal vein is particularly uncommon.
Case presentation
This report describes a 54-year-old Caucasian woman who was admitted to the emergency department with fatigue, severe dyspnea and bilateral lower limb edema. In the first instance this anamnesis suggested possible heart failure. In fact, our patient presented with multi-organ system failure due to a fistula between an infra-renal aortic aneurysm and an aberrant retro-aortic renal vein.
Conclusions
To our knowledge, this is the first report of a woman with a fistula between an infra-renal aortic aneurysm and an aberrant retro-aortic left renal vein. Aorto-venous fistulas may be asymptomatic or may present with symptoms characteristic of arterio-venous shunting and/or aneurysm rupture. This type of fistula is a rare cause of heart failure. Clinical examination and imaging are essential for detection.
