Pyruvate dehydrogenase and pyruvate carboxylase deficiency are the most common disorders in pyruvate metabolism. Diagnosis is made by enzymatic and DNA analysis after basic biochemical tests in plasma, urine, and CSF. Pyruvate dehydrogenase has three main subunits, an additional E3-binding protein and two complex regulatory enzymes. Most frequent are deficiencies in PDH-E1α. There is a spectrum of clinical presentations in E1α deficiency, ranging in boys from severe neonatal lactic acidosis, Leigh encephalopathy, to later onset of neurological disease such as intermittent ataxia or dystonia. Females tend to have a more uniform presentation resembling nonprogressive cerebral palsy. Neuroradiological abnormalities such as corpus callosum agenesis are seen more frequently in girls, basal ganglia and midbrain disturbances in boys. Deficiencies in the other subunits have also been described, but in a smaller number of patients. Pyruvate carboxylase deficiency has three clinical phenotypes. The infantile type is characterized mainly by severe developmental delay, failure to thrive, and seizures. The second type is characterized by neonatal onset of severe lactic acidosis with rigidity and hypokinesia. A third form is rarer with intermittent episodes of lactic acidosis and ketoacidosis. Neuroradiological findings such as cystic periventricular leukomalacia have been described.

This Atlas covers the entire spectrum of brain disease as studied with ultrasound, illustrated throughout with superb-quality images. It is aimed at neonatologists and radiologists confronted with everyday clinical questions on the neonatal ward. Most newborn brain disorders can be identified with ultrasound; this book will therefore be particularly useful in settings with limited MRI facilities. Prenatal ultrasound specialists will also find it valuable as a postnatal reference in their field of interest. Suggestions for differential diagnosis accompany all the sonographic findings, guiding the clinician in proceeding from an abnormal image to a diagnosis. This second edition of the Atlas has been brought up to date to include the many advances in technique and interpretation that have been made in the past decade. The images have been replaced with new ones of higher quality, and all the line artwork has been standardised and improved. Readership Neonatologists, radiologists, neuroradiologists with an interest in neonatal ultrasound From reviews of the first edition: "This is the most challenging and comprehensive book on this theme, and is an essential reference for clinicians to make a correct diagnosis." —Satoshi Takada, Brain and Development "This can be little doubt that this title represents the definitive work on neonatal cranial ultrasound. The authors have had extensive experience in the use of ultrasound scanning the neonatal brain for almost as long as ultrasound has been used to investigate intracranial pathology on the neonatal unit. Their combined experience is most impressive." —Malcolm Leven, Archives of Disease in Childhood
