Myeloperoxidase-positive ANCA-associated vasculitis presenting as myalgia, proximal weakness and a normal CK.

We describe an unusual presentation of myeloperoxidase positive antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis managed by a multidisciplinary approach. A 75-year-old man gave a 3-week history of proximal lower limb weakness and exertional myalgia. His serum creatine kinase was normal and many of his non-specific symptoms suggested small vessel vasculitis.

Assessment of living kidney donors and adherence to national live donor guidelines in the UK.

Background: As in most industrialized countries, living kidney donation has increased considerably in the UK and now amounts to 38% of the total UK kidney transplant activity. Living kidney donation guidelines have been formulated by the relevant national societies. We were interested to study whether or not renal units across the UK adhere to those guidelines and to delineate areas of inconsistency and controversy.
