PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Evaluation of congential toxoplasmosis control programs

The work by Avelino et al. describes the results of evaluation for a control program for congenital toxoplasmosis in Goiania (Brazil). Is difficult to understand some sentences and some of them seem incomplete. Besides language problems, important bias hampers to arrive to conclusions as stated by authors.

The case definitions are not evidence- based clinical or laboratory criteria. For example PCR in newborn sometimes can give to false positive results. Also, specific anti Toxoplasma IgM can give false positive results if taken before day ten of life. 

More surprising is the statement of 5% of congenital cases due to prenatal acquired infection. This merits a detailed description of mother´s and infants serological results including dates and tests that were used to arrive to so significant conclusion.
