Despite the availability of several guidelines on the diagnosis and treatment of antineutrophil cytoplasmic antibody-associated vasculitis (AAV), clinical routine practice will only improve when an implementation strategy is in place to support clinical decision making and adequate implementation of guidelines. We describe here an initiative to establish national and multidisciplinary consensus on broad aspects of the diagnosis and treatment of AAV relevant to daily clinical practice in the Netherlands. ⋯ We present a national, multidisciplinary consensus on a diagnostic strategy and treatment algorithm for AAV patients as part of the implementation of (inter)national guideline-derived recommendations in the Netherlands. Future studies will focus on evaluating local implementation of treatment protocols for AAV, and assessments of current and future clinical practice variation in the care for AAV patients in the Netherlands.

Decreased bone mineral density (BMD) in oestrogendeficient states has long been thought to be a direct outcome of the reduction in oestrogen. In physiologic and many pathologic hypo-oestrogenic states, oestrogen supplementation improves BMD. However, the relationship between oestrogen replacement and BMD is less clear in the case of reproductive axis dysfunction secondary to decreased caloric intake or increased energy expenditure, such as in female athletes or anorexia nervosa. ⋯ This suggests that the decrease in BMD in these states is not driven solely by low oestrogen. Cortisol and other markers of inflammation may play a role in BMD reduction but further research is needed. What is clear is that increased caloric consumption and restoration of menses and the reproductive axis are essential to improving BMD, while pharmacologic therapy, including oestrogen replacement through hormone therapy or contraceptives, does not provide conclusive benefit.

Hyperactive thyroid nodules (HTN) are usually treated with radioactive iodine (RAI). However, as RAI is associated with a 30-60% long-term risk of permanent hypothyroidism, radiofrequency ablation (RFA) may be a good alternative. Primary aim of this study was to assess the percentage of patients achieving euthyroidism after RFA. ⋯ These data suggest that RFA is a safe and promising treatment for symptomatic hyperactive thyroid nodules, with a low risk of permanent hypothyroidism. Long-term studies are needed to identify the recurrence risk of hyperthyroidism.
