    Notizen: Abstract Tetrahydrobiopterin (BH4) deficiency is a rare cause of hyperphenylalaninaemia (HPA) and usually leads to progressive neurological deterioration despite early dietary control of plasma phenylalanine concentrations. Dihydropteridine reductase (DHPR) deficiency is the most severe cause with respect to a fatal outcome. We report a 7-year-old girl with HPA diagnosed on neonatal Guthrie screening who at the age of 6 months had cytotoxic therapy for an adrenal neuroblastoma which secreted catecholamines. When 4 years old she was found to have DHPR deficiency. Although developmentally retarded and microcephalic she has failed to develop the florid neurological features often associated with the condition.

    Notizen: Abstract Trabecular bone mineral content was assessed by quantitative computed tomography in eleven young adults with phenylketonuria who had been treated from early childhood with a diet restricted in natural protein and supplemented with amino acids, minerals and vitamins. There was a significant reduction in the bone mineral content of patients compared with the normal population. Prospective studies are indicated in younger patients to ensure optimum bone mineralisation is achieved by adulthood.

    Notizen: Abstract A radiograph of the left hand and wrist was taken in 141 children and young adults with phenylketonuria and hyperphenylalaninaemia. Ten (7.1%) had a bony abnormality and, of these, six (4.3%) showed evidence of reduced bone density. Only one patient had evidence of spiculation of the lower ulnar metaphysis previously described in phenylketonuria. Bone maturity was also assessed in 130 patients by the Tanner-Whitehouse (TW2) method. In 28 patients (21.5%) bone age was less than chronological age by 1 year or more. Bone age delay was greater in younger children on a more restricted diet with a lower intake of natural protein.
