Fetal damage due to maternal phenylketonuria: effects of dietary treatment and maternal phenylalanine concentrations around the time of conception (an interim report from the UK Phenylketonuria Register).

In 94 infants born to women with PKU, birth weight and head circumference were inversely and linearly related to the mothers' phenylalanine concentrations close to conception; with each 200 mumols/L rise in phenylalanine concentrations, birth weight fell by 98 g and head circumference by 0.46 cm. This relationship was highly significant and appeared to be the same whether or not the mother received a low phenylalanine diet. Even in the 28 infants whose mothers conceived on a strict low phenylalanine diet, birth weights and head circumferences, corrected for sex and gestation, were a little below the population norms (3421 g and 34.7 cm compared with 3600 g and 35.2 cm respectively) although the differences were not statistically significant. Optimal fetal growth occurred only in infants whose mothers had phenylalanine concentrations close to the normal range at conception. Dietary treatment started after conception did not appear to confer any benefit.

Early treated hypothyroidism: development at 3 years.

Eighty children from the North West and North East Thames Regional Health Authorities who had been identified as having congenital hypothyroidism either by neonatal screening (76 cases) or by clinical symptoms (four) were seen for psychological assessments at 1 (60 cases), 3 (58), and/or 5 (20) years of age. Almost all the children's scores were in the normal range, and comparisons with matched controls suggested that they were doing only slightly less well than normal children in overall development. They were significantly slower, however, on a motor skills task. Moreover, a low initial serum thyroxine and triiodothyronine value, considerable delay in initial bone age, and an absence of thyroid tissue on isotope scan seemed to be associated with a somewhat poorer prognosis.
