Toxo-net is a regional program of survey on congenital toxoplasmosis which has two aims: 1) to estimate the incidence of gestational and congenital toxoplasmosis in our Region (Piemonte); 2) to assess the compliance to our diagnostic, therapeutic and follow-up protocols which are thoroughly described. Thirty-two obstetrical, neonatal and laboratory units of Piemonte Region have been involved. During 18 months (January 1997-June 1998) 365 pregnant women were studied because of suspected seroconversion: in 129 patients infection was confirmed. Amniocentesis for prenatal diagnosis was carried on 11 patients; two fetuses were affected. 35% of the mothers were untreated or inadequately treated. Hydrocephaly was observed in two fetuses. Neonatal follow-up at 12 months is available for 68 of the 129 infected mothers. Four babies (5.8%) were infected, three of them being symptomatic; their mothers had not been treated. It is concluded that the implementation of a screening program for toxoplasmosis during pregnancy seems to be beneficial. However an effort to improve the surveillance system and the education of the gynecologists, general practitioners and of the patients is needed, and economic evaluations are warranted.

Abstract
Toxo-net is a regional program of survey on congenital toxoplasmosis which has two aims: 1) to estimate the incidence of gestational and congenital toxoplasmosis in our Region (Piemonte); 2) to assess the compliance to our diagnostic, therapeutic and follow-up protocols which are thoroughly described. Thirty-two obstetrical, neonatal and laboratory units of Piemonte Region have been involved. During 18 months (January 1997-June 1998) 365 pregnant women were studied because of suspected seroconversion: in 129 patients infection was confirmed. Amniocentesis for prenatal diagnosis was carried on 11 patients; two fetuses were affected. 35% of the mothers were untreated or inadequately treated. Hydrocephaly was observed in two fetuses. Neonatal follow-up at 12 months is available for 68 of the 129 infected mothers. Four babies (5.8%) were infected, three of them being symptomatic; their mothers had not been treated. It is concluded that the implementation of a screening program for toxoplasmosis during pregnancy seems to be beneficial.
