Introducing evidence-based family assessment and therapy in child and youth mental health services: Applying systemic principles to maintain, sustain and build capacity

The purpose of this article is to overview the context of the mental health service in which we work, and family therapy's status prior to and after the impact of changes wrought by the introduction of the National Mental Health Policy. We then explore some key issues that we think contribute to the persistence of the occlusion of family therapy in child psychiatric services; and the strategies that we developed and are continuing to develop to support change, finally, we describe the use of a family assessment instrument that we believe is central to our change strategy.

8-Hydroxydeoxyguanosine. A marker of oxidative DNA damage in systemic lupus erythematosus

8-Hydroxydeoxyguanosine (80HDG) is a specific marker of oxidative damage to DNA. We have observed that patients with SLE (systemic lupus erythematosus), have undetectable levels of urinary 80HDG by HPLC. Further analysis by GC-MS confirmed that levels of 80HDG in SLE urine were 10(3)-fold lower than in an age- and sex-matched control group. Experiments utilising cultures of SLE and normal lymphocytes exposed to H2O2 confirmed the impaired ability of SLE lymphocytes to repair 80HDG. We subsequently observed in SLE patients that 80HDG had accumulated in low molecular weight DNA associated with circulating immune complexes. We suggest that oxygen radicals may induce pathology in SLE by maintaining the presence of an antigenic form of DNA in the circulation.
