Abstract
EUROCAT is a European network of population-based congenital anomaly (CA) registries. Twenty-one registries agreed to participate in the EUROlinkCAT study to determine if reliable information on the survival of children born with a major CA between 1995 and 2014 can be obtained through linkage to national vital statistics or mortality records. Live birth children with a CA could be linked using personal identifiers to either their national vital statistics (including birth records, death records, hospital records) or to mortality records only, depending on the data available within each region. In total, 18 of 21 registries with data on 192,862 children born with congenital anomalies participated in the study. One registry was unable to get ethical approval to participate and linkage was not possible for two registries due to local reasons. Eleven registries linked to vital statistics and seven registries linked to mortality records only; one of the latter only had identification numbers for 78% of cases, hence it was excluded from further analysis. For registries linking to vital statistics: six linked over 95% of their cases for all years and five were unable to link at least 85% of all live born CA children in the earlier years of the study. No estimate of linkage success could be calculated for registries linking to mortality records. Irrespective of linkage method, deaths that occurred during the first week of life were over three times less likely to be linked compared to deaths occurring after the first week of life. Linkage to vital statistics can provide accurate estimates of survival of children with CAs in some European countries. Bias arises when linkage is not successful, as early neonatal deaths were less likely to be linked. Linkage to mortality records only cannot be recommended, as linkage quality, and hence bias, cannot be assessed.

Abstract
OBJECTIVES Collection and assessment of data from the Emilia-Romagna Region on the occurrence of congenital heart defects in order to identify an homogeneous group of patients for further aetiologic and genetic studies. MATERIALS AND METHODS The present study is based on 1549 stillborn and live born babies affected by congenital heart defect out of 330,017 consecutive births (4.7 per 1000). RESULTS The frequency and type of congenital heart defects have been identified together with the sex ratio, associated extracardiac anomalies, chromosomal anomalies and the risk of precurrence in relatives. The impact of prenatal diagnosis on prevalence was low during the study period. CONCLUSIONS The study has provided epidemiological data for public health surveillance of congenital heart defects in the Emilia-Romagna region. The creation of a system for the nationwide recording of congenital heart defects designed with regard to the sources of ascertainment, the diagnostic criteria, and the system of classification is emphasised.

Abstract
In toxoplasmosis serodiagnosis the complement fixation reaction (CF) is barely sensitive and specific and supplies results below the general standard levels of this technique. The reasons for this deficiency are discussed and detected in the preparation modalities of the toxoplasma antigens. Two diagnostic antigens are prepared and evaluated; the former, a suspension of whole toxoplasma (WT) the latter a total extract of toxoplasma (TET). The antigens are characterized by the preparative process, culture host and the extractive technique with a modified ultrasonic disintegrator. The antigens are used in the CF reaction, performed with the modified LBCF method, with a 100% hemolysis reading (H 100). The LBCF-H 100 reaction with WT and TET antigens is evaluated parellely to the indirect immunofluorescence reaction (IF) and dye test (DT) on 2514 human sera from cases os suspected toxoplasmosis and pregnant women. The analysis of the serological results pointed out that the LBCF-H 100 reaction performed with WT antigen, shows a sensitivity and specificity equivalent to that of the DT. The LBCF-H 100 reaction with TET antigen extends the range of the antibodies detectable with WT antigen. The optimal serological combination to identify the highest number of seropositive cases of toxplasma infection is given by LBCF-TET and IF reactions.
