[Neonatal screening of congenital hypothyroidism with TSH measurement in dried blood spots on filter paper. A two years experience (author's transl)].

Systematic screening for congenital hypothyroidism was started in Lyon in september 1976. This screening was coupled with PKU, using the same dried blood samples on filter paper obtained on the 5th day of life. TSH levels were determined by radioimmunoassay adapted for dried blood samples (Kit Abbott). In 24 months, 56 176 samples were analyzed. The critical level calling for control was successively raised from from 20 to 30, now 40 microUI/ml of serum. A high level of TSH was found in 307 children (0,55%). Pathological deliveries were found in most of these infants (neonatal injury, cesarean, section forceps or ocytocic perfusion, neonatal icterus) and a second or a third measurement showed normal TSH level. Congenital hypothyroidism, was found detected in 18 infants: 12 ectopic gland, 5 athyreosis and 1 dyshormonogenesis. Treatment was begun at a mean age of 38 days (29 to 50 days).

[Neonatal screening for congenital hypothyroidism by measuring TSH in dried blood samples. Two years experience in the method (author's transl)].

Systematic screening for congenital hypothyroidism was started in Lyon in September 1976. This screening was coupled with PKU screening, using the same dried blood samples in filter paper obtained on the 5 th day of life. TSH levels were determined by radioimmunoassay adapted for dried blood samples (Kit Abbott). In 24 months, 56 176 samples were analyzed. The critical level calling for control was successively raised from 20 to 30 now 40 muUl/ml of serum. A high level of TSH was found in 307 children (0.55 p. 100). Pathological deliveries were found in most of these infants (neonatal injury, cesarean section, forceps or ocytocic perfusion, neonatal icterus) and a second or a third measurement showed normal TSH level. Congenital hypothyroidism, was detected in 18 infants: 12 ectopic gland, 5 athyreosis and 1 dyshormonogenesis. Treatment was begun at a mean age of 38 days (29 to 50 days). Despite a short follow-up the psychomotor development of the infants seems to be normal in all cases but one (one athyreosis with a neonatal injury and a malformative syndrome).

[Clinical significance of plasma renin, testosterone, 17-alpha-hydroxyprogesterone and ACTH activities in the treatment of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. A review of 31 cases].

Measurements of urinary steroids do not allow a precise supervision of the evolution and treatment of congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Thirty-one cases with a 2 year follow-up allowed a trial of estimation of the progress that could be obtained with plasmatic dosages of renine, testosterone, A.C.T.H. and 17-hydroxyprogesterone (17-O.H.P.) activities. The best way for reaching diagnosis is presently 17-O.H.P. However, the amplitude and variability of nyctemeral changes of 17-O.H.P. as well as A.C.T.H. activities do not allow to use these two dosages for a precise supervision of therapeutic effects. On the contrary, the dosage of testosterone allows the appreciation of the risk of virilization and its reliability gives a precise control of the effects of steroid therapy. The dosage of the renine activity disclosed unknown or not well controlled sodium-losses, and allowed to adjust the dosage of 9-alpha-fluorohydro-cortisone, while limiting glucocorticosteroids. It gave also evidence of the usefulness of prolonged steroid therapy until the end of the growth period.
