6. Ion-exchange water softeners This was an observer-blind randomised trial involving 336 children (aged 6 months to 16 years) with moderate/severe atopic eczema randomised to either installation of an ion-exchange water softener plus usual eczema care, or usual eczema care alone The primary outcome was change in eczema severity (Six Area Six Sign Atopic Dermatitis Score, SASSAD) at 12 weeks The mean change in SASSAD at 12 weeks was -5.0 (20% improvement) for the water softener group and -5.7 (22% improvement) for the usual care group A randomised controlled trial of ion-exchange water softeners for the treatment of eczema in childrenThomas KS, Dean T, O'Leary C, Sach TH, Koller K, Frost A, Williams HC; SWET Trial Team.

Chinese Herbal medicine Four trials located The trials randomised 159 participants aged from 1 to 60 years Three trials were randomised placebo controlled, two-phase cross-over designs assessing the same Chinese herbal mixture, Zemaphyte In two of these three trials the reduction in erythema and surface damage was greater on Zemaphyte than on placebo, and participants slept better and expressed a preference for Zemaphyte Zemaphyte is no longer being manufactured.

9. What's new in atopic eczema? An analysis of systematic reviews published in 2009-2010 Shams K, Grindlay DJ, Williams HC. Clin Exp Dermatol. 2011 Aug;36(6):573-7; quiz 577-8 There was no good evidence on the possible benefit of organic food consumption and eczema An inverse relationship has been found between gliomas/acute lymphoblastic leukaemia and allergic disease/eczema The risk of eczema seems to be increased in urban compared with rural areas An updated Cochrane Review still found no evidence of a benefit from any form of antistaphylococcal treatment in managing clinically infected or uninfected eczema Attention deficit hyperactivity disorder does appear to be associated with eczema, but there is no evidence of a causal link
