The Editorial Executive Committee welcomes letters, which should be less than 250 words. Before a decision to publish is made, letters which refer to a published article may be sent to the author for a response. Any letter may be sent to an expert for comment. When letters are published, they are usually accompanied in the same issue by their responses or comments. The Committee screens out discourteous, inaccurate or libellous statements. The letters are sub-edited before publication. Authors are required to declare any conflicts of interest. The Committee's decision on publication is final.

Letter to the editor

Editor, – In the article 'Treatment of ocular toxoplasmosis' (Aust Prescr 2002;25:88-90) sulfadiazine is described as a sulfur analogue. It is, however, a sulfa analogue as sulfur is the element and sulfa, or sulfonamide, is the class of antimicrobial having the chemical group -SO2NHR in its structure.
