[Bilateral hypothenar hammer syndrome].

Hypothenar hammer syndrome is caused by ulnar artery occlusion subsequent to repeated blunt trauma such as by using the hypothenar as a hammer during work. Allen's test permits the detection of this frequent and often overlooked cause of hand pain and ischaemia. The four bilateral hypothenar hammer syndromes described in this case report occurred after several years of occupational exposure to hard shocks/impacts to the hypothenar from workpieces, which were held with a firm grip.

Surgical complications and graft survival in pediatric kidney transplant recipients treated with a steroid-free protocol: experiences from a Danish university hospital.

Background: The outcome of pediatric kidney transplantation depends on several factors, among these are the complications, which occur in relation to the surgical procedure. In this study, we present our experience with pediatric kidney transplantation in a steroid-free immunosuppression regimen, from a surgical point of view.

Methods: Patient charts of pediatric kidney transplantations in the period 1998-2011 were reviewed.

[Rupture risk of abdominal aortic aneurysms].

Abdominal aortic aneurysm (AAA) rupture causes 2% of all deaths among men aged 65 years or more. Since aneurysmectomy is associated with an operative mortality reaching 5%, the risk of rupture determines whether prophylactic surgery should be performed or not. Many studies have been carried out to estimate the risk of rupture, but the results vary greatly.
