AIM To describe the phenotype and genotype of pyruvate dehydrogenase complex (PDHc) deficiency. METHOD Twenty-two participants with enzymologically and genetically confirmed PDHc deficiency were analysed for clinical and imaging features over a 15-year period. RESULTS Four groups were identified: (1) those with neonatal encephalopathy with lactic(More)
OBJECTIVE Pyruvate carboxylase (PC) deficiency is a rare metabolic disease. Recently, therapeutic possibilities have been introduced. We aimed to report the largest series of the B type of PC deficiency, focusing on some neurological aspects that have not yet been documented. METHODS We retrospectively studied nine patients with the severe neonatal form(More)
INTRODUCTION Menkes disease is an X-linked inherited disorder of intestinal copper absorption resulting in copper deficiency. Cardinal features include hair abnormalities, facial dysmorphism, severe neurological impairment, hypothermia, arterial anomalies, bone abnormalities and a fatal outcome. CASE REPORT We present a case of Menkes disease complicated(More)
Glutaric aciduria type 1 (GA1) is an autosomal recessive neurometabolic disorder due to glutaryl CoA dehydrogenase deficiency. Comprehensive descriptions of GA1-associated movement disorders are rare. In order to refine the description of the motor phenotype, we prospectively studied 16 consecutive pediatric and adult GA1 patients, focusing on the movement(More)
Clinical history and inappropriate insulin secretion during hypoglycemic episodes permit the diagnosis of hyperinsulinism. We report 2 cases of factitious hyperinsulinism leading to partial pancreatectomy. Case 1 was an 8-year-old girl who presented with severe hypoglycemia and elevated insulin and C-peptide levels. Catheterization of pancreatic veins was(More)
This paper reviews the clinical presentation of 217 patients with urea cycle defects, including 121 patients with neonatal-onset forms and 96 patients with late-onset forms. Long-term outcome of these patients is also reported with the severity of the neonatal forms of these disorders, mostly for ornithine carbamoyltransferase-deficient males. Patients with(More)
AIM Having previously shown that comorbidity is a major determinant of neurological sequelae in hypoglycaemia, our aim was to describe the neuroimaging patterns of brain damage in different hypoglycaemic situations and to elucidate the factors that determine lesion topography. METHOD We reviewed 50 patients (31 females, 19 males) with symptomatic(More)
AIM To determine risk factors for neurological sequelae following hypoglycemia. METHOD We analysed the neurological outcome in 164 patients (mean age 10y 10mo, SD 5.9) following hypoglycemia due to three diseases with various metabolic contexts, different ages at onset, and combinations with comorbidity (fever/infection, hypoxia/ischemia): glycogen(More)
Infantile spasms (or West syndrome) occur occasionally in patients with branched-chain organic acidurias. We describe a patient diagnosed with methylmalonic aciduria at 4.5 months of age during an episode of metabolic decompensation. The child was developmentally delayed and hypotonic; his electroencephalography (EEG) showed hypsarrythmia and brain magnetic(More)
Propionic acidemia is an inborn deficiency of propionyl-coenzyme A (CoA) carboxylase activity, which leads to mitochondrial accumulation of propionyl-CoA and its by-products. Neurologic complications are frequent, but only a few cases presenting with psychiatric symptoms have been reported so far. We report 2 cases of children with chronic psychiatric(More)
