67 obstetrical and gynecological physicians and 102 professional staff members of family planning clinics (FPCs) in the Pittsburgh, Pennsylvania, area returned questionnaires relating to knowledge of basic genetic principles and attitudes towards genetic screening and genetic counseling. The best understood genetic risk was Down's syndrome in children born to mothers over 40 years of age. Nearly 90% of physicians and 85% of FPC staff knew this but only 12% of physicians and 30% of FPC staff knew it is caused by chromosomal aberration. Next best understood defect is sickle cell anemia. In overall knowledge the physicians had a mean score of 4.45 of 7 genetic questions, FPC staff, 3.32. However, FPC workers who had received in-service genetic training scored 4.42 (p less than .001). Knowledge of the 2 genetic clinics in the area and acceptance of the principles of genetic screening were associated with the individual's acceptance of sterilization as a method of birth control and acceptance of abortion if the fetus had significant risk of being born deformed. Both of these associations were at the significant level for both physicians and FPC workers. Both physicians and FPC workers who have themselves had genetic counseling or who have family members who have had such counseling show higher acceptance levels. An association was also found between acceptance and genetic educational background. About 92% of respondents who had read articles or textbooks pertaining to genetics during the preceding year approved of including genetic information as part of maternal and child health projects compared with 82% of those who had not (p less than .02). Among the physicians 36% felt it should be required, 34% voluntary, and 30% did not know; for FPC workers, 59, 27, and 14%, respectively. Protestants and Jews tended to favor required premarital screening while Catholics tended to oppose it (p less than .007). It is disconcerting that over 50% of the physicians did not know the recurrence risk of PKU and over 20% did not know the gene is the basic unit of inheritance. While it is true that over 1/2 completed basic professional education more than 20 years ago when genetics was not part of the medical school curriculums this basic knowledge needs to have been acquired during continuing medical education. In this study more than 1/3 of the FPC staff indicated they had been asked to provide genetic counseling or had referred clients. This points up the importance of such workers in a comprehensive genetic counseling service.

France has decided to add to the national neonatal screening program (Phenylketonuria, Hypothyroidism, Congenital Adrenal Hyperplasia, Sickle cell disease) the screening of cystic fibrosis (CF). The screening of CF will be implemented in all regions of France by the end of 2002 and will cover all newborn (near 800,000/year). Based on the recommendation of the French Screening Foundation, the project has been approved by the Health Ministry and will be financed by the social security. CF neonatal screening is now technically feasible and reliable. The proposed methodology includes: immunoreactive trypsin (IRT) dosage on all newborns at day 3 (by radioimmunology "Cis Bio" or immunofluorescence "Delfia") followed by genotype CFTR analysis if IRT level is above 60 micrograms/L. Screening for 29 mutations is planned. If genotype is negative, control of IRT at day 21 will be obtained. Several requirements are included in the program: a protocol of care for the newly diagnosed CF in a specialised CF center; information to all parents of newborns; results of CFTR genotype has to be given during a clinical visit, even if negative. This screening program should allow to screen 98% of the cystic fibrosis patients before the age of 1 month. In order to ensure perfect efficacy, the CF screening program will be evaluated and modified if necessary.

Timely recognition of clinical signs and symptoms of sickle cell disease remains of great importance because the neonatal PKU screening program in The Netherlands that was introduced in January 1st 2007 will not reach all children with this disease. Of children that have been diagnosed in the Emma Children's Hospital AMC, Amsterdam, 20% would not have been reached by this new program: immigrant's children born abroad and adopted children. It goes without saying that also in children that have been born in the Netherlands before January 1st 2007 the diagnosis sickle cell disease should be considered in cases of disease-specific clinical symptoms. The initial clinical manifestation of sickle cell disease in children born in the Netherlands is potentially life-threatening in 8% (7/88), e.g. a pneumococcal infection or an acute splenic sequestration. Painful crisis, paleness and jaundice are the most common presenting symptoms. The median age at diagnosis of the group of Amsterdam children was 25 months. In view of the potential health benefit it is advised to test children from populations at risk, that are under the medical attention of a hospital for any reason, for the presence of sickle cell disease. This applies especially to children with a pneumococcal infection.
