Authors summarized the etiology of convulsions in neonatal period and infancy (hypoxia, intracranial hemorrhage, infections of central nervous system, metabolic background, chromosomal abnormalities, brain developmental abnormalities, benign neonatal convulsions, benign neonatal familial
N-carbamylglutamate (NCG) has been reported to decrease ammonia levels in patients with propionic aciduria (PA) and methylmalonic aciduria (MMA), but reports on clinical outcomes remain scant. Here, we report a retrospective series of four patients with neonatal PA treated with NCG at presentation.
Non-ketotic hyperglycinemia (NKH) has been diagnosed in two sibs. At the age 2:5 years and 1:3 years respectively only moderate psycho-motor retardation and muscular hypotonia were seen in the elderly child while no psycho-neurological symptoms were seen in the younger sib. Neither of the children
BACKGROUND
Organic acidurias have long been known to cause neurological problems, such as convulsions, stupor, coma, and psychomotor and mental retardation. The organic acidurias include propionic aciduria, methylmalonic aciduria (MMA), isovaleric acidemia, lactic acidemia and glutaric acidemia type
BACKGROUND
Patients with propionic acidemia usually present in the neonatal period with life-threatening ketoacidosis, often complicated by hyperammonemia. It was thought that the neurologic abnormalities seen in this disease were exclusively the consequences of these acute crises. Experience with 2
Oxidative stress contributes to the pathogenesis of propionic acidemia (PA), a life threatening disease caused by the deficiency of propionyl CoA-carboxylase, in the catabolic pathway of branched-chain amino acids, odd-number chain fatty acids and cholesterol. Patients develop multisystemic
A 12-month-old boy diagnosed with propionic acidemia underwent gastrostomy. The patient's general state was good and he was alert, but with reduced muscular tone (unstable when seated with support, floppy head) and with dystonic movements in all extremities. An electroencephalogram showed slightly
Propionic acidemia is a relatively rare inborn error of metabolism. Individuals with propionic acidemia often have life-threatening episodes of hyperammonemia and metabolic acidosis, as well as intellectual disability. There are many reports of additional problems, including poor growth, stroke-like
A case of propionic acidemia is reported. The main features of this patient were recurrent vomiting, ketosis and occasional episodes of seizure. Serum concentrations of propionic acid and glycine were within the normal range. Blood ammonia was slightly elevated. Characteristic organic acids were
Propionic acidemia (PA) is an autosomal recessively inherited defect of propionyl-CoA carboxylase with an incidence of approximately 1:50 000. There are few reports on the occurrence of EEG findings and development of epilepsy in patients with PA. Retrospectively, the data of 17 patients with PA
Propionic acidemia (PA) is a rare organic acidemia resulting from a deficiency of the mitochondrial enzyme propionyl-coenzyme A carboxylase. Most cases are diagnosed after the detection of metabolic abnormalities-such as hyperammonemia, metabolic acidosis, and ketosis-associated with complaints of
Propionic acidemia is an inborn error of metabolism that is inherited in an autosomal recessive manner. It is characterized by a deficient propionyl-CoA carboxylase due to mutations in either of its beta or alpha subunits. In the literature, there is a clear association between propionic acidemia
Propionic acidemia is a metabolic disorder (OMIM 606054) caused by deficiency of the propionyl-coenzyme A (CoA) carboxylase, which subsequently results in accumulation of propionic acid. Patients may initially present with poor feeding, vomiting, loss of appetite, hypotonia, and lethargy. Later,
Propionic acidemia (PA) is an organic acidemia which has a broad range of neurological complications, including developmental delay, intellectual disability, structural abnormalities, metabolic stroke-like episodes, seizures, optic neuropathy, and cranial nerve abnormalities. As the PA consensus
