A 6-month-old girl developed intermittent dystonic posture of the legs and eczematous dermatitis without ataxia. Qualitative and quantitative urine amino acid testing confirmed the diagnosis of Hartnup disease. Cranial computed tomography, electroencephalogram, electromyogram/nerve conduction study, posterior tibial somatosensory evoked potentials, 24-hour electroencephalographic telemetry, and metrizamide myelogram were normal. Spinal fluid hydroxy-indoleacetic acid concentration was less than… Expand
Update on pediatric dystonias: etiology, epidemiology, and management.
TLDR
Dystonia is a movement disorder characterized by sustained muscle contractions producing twisting, repetitive, and patterned movements or abnormal postures that can be secondary to virtually any pathological process that affects the motor system, and particularly the basal ganglia. Expand

Spontaneous Scalp Arteriovenous Fistula in a Child with Hartnup Disease
TLDR
The endovascular treatment of a spontaneous scalp arteriovenous fistula (AVF) in a child with Hartnup disease is reported, indicating that scalp AVFs may progress in size, causing significantly disabling symptoms, particularly in children. Expand
Nonprimary dystonias.
TLDR
The most effective treatment for focal and segmental dystonias is local botulinum toxin injections and deep brain stimulation of the globus pallidus internus is effective for generalized dystonia. Expand
Episodic ataxia and channelopathies
TLDR
The possible role of the channelopathies in the causation of some periodic neurological disorders is considered, and the treatment of the episodic ataxias with acetazolamide can sometimes have a dramatic effect. Expand
Further evidence for allelic heterogeneity in Hartnup disorder
TLDR
It is demonstrated that Hartnup disorder is allelically heterogeneous with two mutated SLC6A19 alleles, whether identical or not, necessary for manifestation of the characteristic aminoaciduria in affected individuals. Expand
Treatable inborn errors of metabolism presenting as cerebral palsy mimics: systematic literature review
TLDR
A surprisingly large number of IEMs can present with CP symptoms, as ‘CP mimics’, and a large proportion of these diseases are treatable such that neurological damage can either be reversed or prevented. Expand
Inherited Metabolic Disorders with Associated Movement Abnormalities
TLDR
In this chapter, the metabolic abnormality, clinical presentation, diagnosis, and treatment for various conditions are presented in a disorder-based framework. Expand
Transport Defects of Amino Acids at the Cell Membrane: Cystinuria, Hartnup Disease, and Lysinuric Protein Intolerance
Inherited defects in amino acid transport at the cell membrane are usually expressed as selective renal aminoaciduria, i.e., the concentration of affected amino acids is high in the urine, but normalExpand

Background  Hartnup disease is a rare autosomal‐recessive abnormality of renal and gastrointestinal neutral amino acid transport associated with neurologic, psychiatric, and dermatologic symptoms.Expand

Hartnup disease. Clinical, pathological, and biochemical observations.
TLDR
In vivo and in vitro studies of intestinal amino acid transport in the surviving sibling indicated a partial defect in the transport of several neutral amino acids with normal transport of otherneutral amino acids. Expand
Lisuride in dystonia
TLDR
Lisuride hydrogen maleate was given orally to 42 subjects with various types of dystonia and improved some patients, but had no effect on other, apparently identical, patients. Expand
High dosage anticholinergic therapy in dystonia
TLDR
Twenty-three children and 52 adults with torsion dystonia of various etiologies and distribution patterns of the involuntary movements were treated in an open-label study with anticholinergic medication, and significant benefit occurred in 61% of children and in 38% of adults. Expand
Cerebrospinal fluid neurotransmitter metabolites in neurologically normal infants and children.
TLDR
This study demonstrates a previously undetected age effect on CSF MHPG concentration during the neonatal period and provides valuable normal data that are necessary for the interpretation of CSF monoamine metabolites in infants and children with hyperphenylalaninemia and other neurologic disease involving monoamine neurotransmitters. Expand
Acute Changes in Brain Tryptophan and Serotonin After Carbohydrate or Protein Ingestion by Diabetic Rats
TLDR
The diabetic rat's inability to experience normal carbohydrate-induced increments in brain serotonin suggests that brain functions, normally dependent on such neurochemical signals, may be abnormal. Expand
NEUTRAL AMINO ACIDS IN THE BRAIN: CHANGES IN RESPONSE TO FOOD INGESTION 1
TLDR
The diet‐induced changes in the brain level of each of the amino acids also correlate surprisingly well with the calculated rate of brain influx for each amino acid. Expand
Brain Serotonin Content: Physiological Regulation by Plasma Neutral Amino Acids
TLDR
The main determinant of brain tryPTophan and serotonin concentrations does not appear to be plasma tryptophan alone, but the ratio of this amino acid to other plasma neutral amino acids that compete with it for uptake into the brain. Expand
