CASE STUDY MSUD

We present a neonate with the classic subtype of MSUD and its imaging features on magnetic resonance imaging. In addition, diffuse white matter abnormalities may be seen on T2-weighted sequences [ Figure 2 ]. A diet which restricts amino acids is necessary in treating the disease. There must be ways to screen for this disease as well. A homozygous dominant individual should have normal amino acid blood levels because they have to functional alleles in their genome. 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.

It has an annual incidence of 1 in , live births worldwide. MRI shows marked restricted diffusion, reflecting intracellular edema cytotoxic edema , involving the corticospinal tracts posterior limbs of the internal capsule , thalami, globus palladi, midbrain, dorsal brain stem, and cerebellar white matter [ Figure 1 ]. The patient’s newborn screenings were abnormal, showing elevated BCAAs. Neuropsychiatry, Neuropsychology and Behavioral Neurology. This case study describes the developmental history and behavioral and neuropsychological sequelae of maple syrup urine disease MSUD in an year-old male. Heterozygous carriers are not affected by MSUD, but only have one functional allele.

Leave this field empty. It has an annual incidence of 1 inlive births worldwide. There must be ways to screen for this disease as well. If untreated, the disease progresses to cause seizures, coma, and eventually, death. On physical examination, he was found to be normothermic, normotensive, and with stable vital signs.

Time of onset may vary stuxy on the amount of protein in the feeding regimen.

There had been no problems through pregnancy and birth, but once Matthew was born, he had failed to thrive. This case study also emphasizes the importance of cognitive and behavioral monitoring of metabolic changes in MSUD patients.

Onset of clinical symptoms and protein levels in the blood and urine may vary depending on the amount of protein in the atudy regimen. We present a neonate with the classic subtype of MSUD and its imaging features on magnetic resonance imaging.

Each of them can be distinguished from the other based on age of onset, severity of clinical symptoms, and response to thiamine. A 2-week-old male infant was born at term after an uneventful pregnancy and a normal vaginal delivery. Your email address will not be published.

Abnormal accumulation of these amino acids results in a variety of symptoms including lethargy, irritability, feeding problems, vomiting, and the characteristic maple-syrup odor of urine.

Management of MSUD involves two aspects: 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 ztudy. In addition, diffuse white matter abnormalities may be seen on T2-weighted sequences [ Figure 2 ].

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 presented with slight irritability and poor feeding in the second week of life. T2-weighted images show extensive edema involving the bilateral cerebellar white matter Abrain stem, Band posterior limbs of internal capsules arrows on C up to the centrum semiovale D.

The patient was thereafter admitted to our hospital where he exhibited irritability, hypertonicity, high-pitched cry, and sleepiness. It is characterized by accumulation of BCAAs and corresponding branched-chain keto acids of leucine, isoleucine, and valine in plasma, urine, and cerebrospinal fluid. Most patients treated within a few days from the onset of symptoms survive and may not develop any residual neurological deficits.

Imaging Findings in Maple Syrup Urine Disease: A Case Report

Intellectual outcome in children with maple syrup urine disease. Newborns are typically normal at birth, develop ketonuria within the first 48 hours of life, and present with irritability, poor feeding, vomiting, lethargy, and dystonia secondarily. A case study of maple syrup urine disease, dietary treatment and neuropsychological performance Eugene K.

Neuropsychiatry, Neuropsychology and Behavioral Neurology5 1 If untreated, sthdy neurological complications including seizures or coma may occur, as BCAAs, especially leucine, are cytotoxic to brain cells, leading to cytotoxic brain edema affecting the myelinated white matter as was seen in the diffusion-weighted imaging DWI of our patient.

What about supplementation of the BCKD protein complex to allow the body to digest the built up amino acids? Left untreated, the disease causes mental retardation, growth retardation, and eventual death.
