Neuroglycopenia in normoglycaemic patients, and the potential benefit of ketosisM A A P Willemsen
Department of Paediatric Neurology, University Medical Centre Nijmegen, Nijmegen, The Netherlands
Diabet Med 20:481-2. 2003..The potential benefit of ketosis in neuroglycopenia is discussed from the therapeutic concept of a ketogenic diet in GLUT1-deficiency syndrome...- Brain-Thyroid-Lung syndrome: a patient with a severe multi-system disorder due to a de novo mutation in the thyroid transcription factor 1 geneMichel A A P Willemsen

Eur J Pediatr 164:28-30. 2005..Introduction of a name for the disorder, e.g. Brain-Thyroid-Lung syndrome, would probably facilitate further recognition. Whether the TITF-1 gene mutation in this patient predisposed to the development of lung cancer remains speculative... - Methylsulfonylmethane (MSM) ingestion causes a significant resonance in proton magnetic resonance spectra of brain and cerebrospinal fluidM A A P Willemsen
Department of Pediatric Neurology, Radboud University Nijmegen Medical Centre, Nijmegen, The Netherlands
Neuropediatrics 37:312-4. 2006..Our findings illustrate that ingestion of exogenous compounds, e.g., in medication, food or "innocent" supplements, may lead to abnormal resonances in spectroscopy studies that might be difficult to assign... - Tyrosine hydroxylase deficiency: a treatable disorder of brain catecholamine biosynthesisMichel A Willemsen
Radboud University Nijmegen Medical Centre, Donders Institute for Brain, Cognition and Behaviour, Department of Paediatric Neurology 820 IKNC, PO Box 9101, 6500 HB Nijmegen, The Netherlands
Brain 133:1810-22. 2010..698G>A and c.707T>C mutations. Carriership of at least one promotor mutation, however, apparently predicts type A tyrosine hydroxylase deficiency. Most patients with tyrosine hydroxylase deficiency can be successfully treated with l-dopa... - Glucose transporter-1 deficiency syndrome: the expanding clinical and genetic spectrum of a treatable disorderWilhelmina G Leen
Department of Neurology, Radboud University Nijmegen Medical Centre, 935 Neurology, PO Box 9101, 6500 HB Nijmegen, The Netherlands
Brain 133:655-70. 2010..Our study demonstrates that a lumbar puncture provides the diagnostic clue to glucose transporter-1 deficiency syndrome and can thereby dramatically reduce diagnostic delay to allow early start of the ketogenic diet... - Rituximab and intravenous immunoglobulins for relapsing postinfectious opsoclonus-myoclonus syndromeWilhelmina G Leen
Department of Pediatric Neurology, Radboud University Nijmegen Medical Center, Nijmegen, The Netherlands
Pediatr Neurol 39:213-7. 2008..Treatment with rituximab in combination with intravenous immunoglobulin, however, resulted in significant longterm clinical improvement... - Two Greek siblings with sepiapterin reductase deficiencyMarcel M Verbeek

J Clin Endocrinol Metab 96:E189-98. 2011..Mutations in ANKH cause the highly divergent conditions familial chondrocalcinosis and craniometaphyseal dysplasia. The gene product ANK is supposed to regulate tissue mineralization by transporting pyrophosphate to the extracellular space... - New mitochondrial tRNA HIS mutation in a family with lactic acidosis and stroke-like episodes (MELAS)Maria Antonietta Calvaruso
