phenylketonurias/seizures

Serial EEC investigations were carried out in 30 children with phenylketonuria aged 8 months to 4 years at the time of dietary treatment. All children had seizures. The results of EEG investigations in this group of children were compared with a preciously observed analogous of 35 children without

This report describes the morphological changes observed in the brain of an untreated 27-year-old man with phenylketonuria, cortical blindness, and seizures. Golgi-Kopsch silver, cresyl violet, and hematoxylin and eosin stains were used to study cell structure and organization of the cerebellum, the

In a group of 90 children with phenylketonuria diagnosed and treated late the authors studied the problem of seizures. They occurred in over 50% of children, in most of them they had the character of salaam seizures (72%). They were statistically significantly more frequent in children with more

Phenylketonuria (PKU) is one of the most common inherited metabolic disorders, which is characterized by excessive accumulation of phenylalanine (Phe) in tissues. Generalized seizures occur in 25% of the patients. Little is known about seizures and their treatment in adult PKU patients, and

We assessed the clinical characteristics and efficacy of neurotransmitters and levetiracetam in a patient with hyperphenylalaninemia due to dihydropteridine reductase (DHPR) deficiency who developed epileptic seizures. A boy with DHPR deficiency, who had been successfully treated with

We report our experience with the deficiency of 6-pyruvoyltetrahydropterin synthase, the most common form of tetrahydrobiopterin deficiency. We investigated 5200 patients suspected of having some inborn error of metabolism in a 10-year period, and detected 30 cases (from 28 sibships) of

This study evaluated the newborn screening program for phenylketonuria (PKU) in Thailand from 1996 to 2006. During the study period, 5,243,841 newborns were screened, of which 16 were confirmed to have PKU. The phenylalanine levels ranged from 20.30-30.68 mg/dl (mean 25.82 mg/dl). All the patients

OBJECTIVE Severe and progressive neurologic disease remains a problem for patients with hyperphenylalaninemia due to a deficiency of tetrahydrobiopterin (BH4), even with early diagnosis and despite treatment with BH4 and neurotransmitter precursors. Few reports have included the associated imaging

Hyperphenylalaninemia in infants and children may be caused by a deficiency of dihydropteridine reductase (DHPR). Recommended therapy includes folinic acid as a source of tetrahydrofolate, a phenylalanine-restricted diet, and both dopamine and serotonin precursors. We report a child with progressive

Phenylketonuria (PKU), is an autosomal recessive condition affecting the amino acid metabolism. The UK National newborn screening programme was commenced in 1969 and PKU is one among the five conditions included in the screening programme. We present the case history of two siblings of a family with

OBJECTIVE To explore the incidence and clinical characteristics of West syndrome associated with phenylketonuria (WS-PKU) and significance of early combination therapy of low phenylalanine (PHE) diet and anticonvulsants (antiepileptic drugs, AEDs) in WS-PKU. METHODS Sixty-two WS-PKU patients (41
