CASE STUDY MSUD

Diagnosis and treatment of maple syrup disease: A homozygous dominant individual should have normal amino acid blood levels because they have to functional alleles in their genome. Computed tomography in maple syrup urine disease. Branched-chain amino acids , magnetic resonance imaging , maple syrup urine disease , myelinated white matter , restricted diffusion. Its name is derived from the smell of the urine of the affected infant.

Heterozygous carriers are not affected by MSUD, but only have one functional allele. Most patients treated within a few days from the onset of symptoms survive and may not develop any residual neurological deficits. Keywords Diet Maple syrup urine disease Neuropsychological. Conflicts of interest There are no conflicts of interest. Leucine is toxic to brain cells, leading to cytotoxic edema affecting the myelinated white matter, and involving the corticospinal tracts, thalami, globus palladi, midbrain, dorsal brain stem, and cerebellum. A homozygous recessive individual is affected by MSUD and will have high amio acid blood levels because they lack a functional allele to produce proper proteins. Chuang D, Shih V.

Maple syrup urine disease: report of two cases.

A 2-week-old male infant was born at term after an uneventful pregnancy and a normal vaginal delivery. Journal List J Pediatr Neurosci v. Computed tomography in maple syrup urine disease.

Maple-syrup odor usually occurs late, during the crisis stage, and may be difficult to identify in the first few days of life.

The patient was thereafter admitted to our hospital where he exhibited irritability, hypertonicity, high-pitched cry, and sleepiness. Onset of clinical symptoms and protein levels in the blood and urine may vary depending on the amount of protein in the feeding regimen.

A homozygous dominant individual should have normal amino acid blood levels because they have to functional alleles in their genome. Neuropsychiatry, Neuropsychology and Behavioral NeurologyVol. Matthew was placed on a strict low protein diet.

On physical examination, he was found to be normothermic, normotensive, and with stable vital signs. Link to citation list in Scopus.

Imaging Findings in Maple Syrup Urine Disease: A Case Report

Time of onset may vary depending on the amount of protein in the feeding regimen. Open in a separate window. This case study describes the developmental history and behavioral and neuropsychological sequelae of maple syrup urine disease MSUD in an year-old male.

The patient’s newborn screenings were abnormal, showing elevated BCAAs. Left untreated, the disease causes mental retardation, growth retardation, and eventual death. Selected tests of neuropsychological and cognitive functioning, administered before dietary treatment and immediately following metabolic stabilization and at 5-week follow-up, indicated considerable clinical improvement.

DWI top row and corresponding apparent diffusion coefficient bottom row demonstrate marked restricted diffusion because of cytotoxic edema involving the cerebellar white matter, dorsal brain stem, thalami, globus palladi, and internal capsules. It is characterized by accumulation of BCAAs and corresponding branched-chain keto acids of leucine, sfudy, and valine in plasma, urine, and cerebrospinal fluid.

These abnormalities resolve promptly after treatment. I understand that a liver transplant could be more effective because then the body is able to synthesize its own enzyme rather than the patient relying on getting regular supplements.

This case study also emphasizes the importance of cognitive and behavioral monitoring of metabolic changes in MSUD patients. Abstract This case study describes the developmental history and casee and neuropsychological sequelae of maple syrup urine disease MSUD in an year-old male.
