2007 Jun 19

New search has been performed

Updated July 2007
In this update, the search for the primary studies up to June 2007 was conducted. Minor changes were made to update the search stragegy. One randomised double‐blind study related to the study topic was found (Paz 2006) but this study was excluded because it assessed the persistence of choreic movements after treatment with prednisone in patients with the diagnosis of Sydenham's Chorea.

The study conclusions have not changed.

2005 May 02

New search has been performed

Updated May 2005
In this update we reran the search for the primary studies up to April 2005. Four potential new studies were found and all were excluded from this review. One study was a review (Naik 2002), one was not a randomised trial (Narin 2003) and while the remaining two trials were randomised clinical trials their outcomes were not relevant. One study had arthritis as the outcome (Hashkes 2003), while the other assessed their patients four weeks after treatment (Camara 2002).

The study conclusions have not been amended. Minor changes have been made to the background. No changes have been made to the methodology. The search strategies are unchanged.
