Diversity of XMEN Disease: Description of 2 Novel Variants and Analysis of the Lymphocyte Phenotype.

Variants in MAGT1 have been identified as the cause of an immune deficiency termed X-linked immunodeficiency with magnesium defect, Epstein-Barr virus (EBV) infection and neoplasia (XMEN) disease. Here, we describe 2 cases of XMEN disease due to novel mutations in MAGT1, one of whom presented with classical features of XMEN disease and another who presented with a novel phenotype including probable CNS vasculitis, HHV-8 negative multicentric Castelman disease and severe molluscum contagiosum, thus highlighting the clinical diversity that may be seen in this condition. Peripheral blood immunophenotyping of these 2 patients, together with an additional 4 XMEN patients, revealed reduced NKG2D expression, impaired CD28 expression on CD8 T cells, CD4 T cell lymphopenia, an inverted CD4:CD8 ratio and decreased memory B cells.

Autoantibodies in interstitial lung diseases.

The role of autoantibody testing for patients with interstitial lung disease is an evolving area. Recent guidelines recommend routine anti-nuclear antibodies, rheumatoid factor, and anti-citrullinated cyclic peptide antibody testing for patients undergoing diagnostic evaluation for interstitial lung disease, with further autoantibody testing reserved for selected cases guided by rheumatological features. Even this approach may miss patients with clinically significant autoantibodies when interstitial lung disease is the dominant or first manifestation of autoimmune disease.

Adequacy of consent documentation in a specialty surgical unit: time for community debate?

Objective: To determine the adequacy of consent documentation related to descriptions of intended procedures, associated risks and treatment alternatives, and to analyse trends in the adequacy of consent documentation in a specialty surgical unit.

Design, Patients And Setting: Retrospective reviews of consent forms for all patients on the Urology Unit waiting list of the Repatriation General Hospital, Adelaide on three occasions. Reviews were undertaken during 2005, 2007 and 2008, with a minimum of 12 months between reviews.
