in which the body cannot properly turn food into energy. The disorders are usually caused by defects in specific proteins (enzymes) that help break down (metabolize) parts inborn errors of metabolism ppt of food. A food product that is not broken down into energy can build up in the body and cause a wide range of symptoms. Several inborn errors of metabolism cause developmental delays or other medical problems if they are not controlled. There are many different types of inborn errors of metabolism. A few of them inborn errors of metabolism screening tests are:Fructose intoleranceGalactosemiaMaple sugar urine disease (MSUD)Phenylketonuria (PKU) Newborn screening tests can identify some of these disorders.Registered dietitians and other health care providers can help create a diet that is right for each specific disorder.Alternative Names Metabolism - inborn errors ofImages Galactosemia References Bodamer OA.

Next Emergency Department Care Delay in recognition and treatment may result in long-term neurologic impairment or death. Initiate treatment as quickly as possible. Initial ED treatment does not require knowledge of the http://emedicine.medscape.com/article/804757-treatment specific metabolic disease or even disease category (see Emergent treatment below).[6] In any critically ill child, airway, breathing, and circulation must be established first. Hypoglycemia, acidosis, and hyperammonemia must be corrected. Consider antibiotics in any child who may be septic. Goals of treatment Goals of treatment for patients with an inborn error of metabolism (IEM) are prevention of further accumulation of harmful substances, correction of metabolic abnormalities, and elimination of toxic metabolites. Even the apparently stable patient with mild symptoms may deteriorate rapidly with progression to death within hours. With appropriate therapy, patients may completely recover without sequelae. Start empiric treatment for a potential inborn error of metabolism as soon as the diagnosis is considered. Treatment of patients with a known inborn error of metabolism should be disease and patient specific. Families may have treatment protocols with them developed by an IEM specialist. They may also have instructions for what resuscitation measures should be given if resuscitation is necessary. Protocols for acute illness are available on the New England Consortium of Metabolic Programs.[2] Emergent
D008661 [edit on Wikidata] Inborn errors of metabolism form a large class of genetic diseases involving congenital disorders of metabolism. The majority are due to defects of single genes that code for https://en.wikipedia.org/wiki/Inborn_error_of_metabolism enzymes that facilitate conversion of various substances (substrates) into others (products). In http://www.medicinenet.com/script/main/art.asp?articlekey=3951 most of the disorders, problems arise due to accumulation of substances which are toxic or interfere with normal function, or to the effects of reduced ability to synthesize essential compounds. Inborn errors of metabolism are now often referred to as congenital metabolic diseases or inherited metabolic diseases. The term inborn inborn error error of metabolism was coined by a British physician, Archibald Garrod (1857–1936), in 1908. He is known for work that prefigured the "one gene-one enzyme" hypothesis, based on his studies on the nature and inheritance of alkaptonuria. His seminal text, Inborn Errors of Metabolism was published in 1923.[1] Contents 1 Classification 2 Signs and symptoms 3 Diagnosis 4 Treatment 5 Epidemiology 6 inborn errors of References 7 External links Classification[edit] Traditionally the inherited metabolic diseases were classified as disorders of carbohydrate metabolism, amino acid metabolism, organic acid metabolism, or lysosomal storage diseases. In recent decades, hundreds of new inherited disorders of metabolism have been discovered and the categories have proliferated. Following are some of the major classes of congenital metabolic diseases, with prominent examples of each class. Many others do not fall into these categories. Disorders of carbohydrate metabolism E.g., glycogen storage disease Disorders of amino acid metabolism E.g., phenylketonuria, maple syrup urine disease, glutaric acidemia type 1 Urea Cycle Disorder or Urea Cycle Defects E.g., Carbamoyl phosphate synthetase I deficiency Disorders of organic acid metabolism (organic acidurias) E.g., alcaptonuria, 2-hydroxyglutaric acidurias Disorders of fatty acid oxidation and mitochondrial metabolism E.g., Medium-chain acyl-coenzyme A dehydrogenase deficiency (often shortened to MCADD.) Disorders of porphyrin metabolism E.g., acute intermittent porphyria Disorders of purine or pyrimidine metabolism E.g., Lesch-Nyhan syndrome Disorders of steroid metabolism E.g., lipoid congenital adrenal hyperplasia, congenital adrenal hyperplasia Disorders of mitochondrial function E.g., Kearns-Sayre syndrome Disorders of peroxisomal function E.g., Zellweger syndrome Lysosomal storage disorders E.g., Gaucher's di
