Lymphoedema in breast cancer patients

Re: "Lymphoedema in breast cancer patients", the letter to the editor by Graeme N Brodie in the 3 March issue of the Journal (Med J Aust 2003; 178: 244), in which washing soda, used in a simple dialysis treatment for lymphoedema, was mistakenly called crystalline calcium carbonate. Washing soda is, in fact, sodium carbonate. The web version of the article was corrected on 4 March 2003.
