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)
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)
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)
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)
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)
BACKGROUND The principal aim of this study was to investigate the long-term outcomes of a large cohort of patients with ornithine transcarbamylase deficiency (OTCD) who were followed up at a single medical center. METHODS We analyzed clinical, biochemical and genetic parameters of 90 patients (84 families, 48 males and 42 females) with OTCD between 1971(More)
BACKGROUND Classical organic acidurias including methylmalonic aciduria (MMA), propionic aciduria (PA) and isovaleric aciduria (IVA) are severe inborn errors of the catabolism of branched-chain amino acids and odd-numbered chain fatty acids, presenting with severe complications. METHODS This study investigated the long-term outcome of 80 patients with(More)
