Maple Syrup Urine Disease Medicine & … HHS The classic presentation occurs in the neonatal period with developmental delay, failure to thrive, feeding difficulties, and maple syrup odor in the cerumen and urine, and can lead to irreversible neurological complications, including stereotypical movements, metabolic decompensation, and death if left untreated. These crises occur during the initial neonatal episode, during which most patients receive their diagnosis, and later following dietary indiscretion, surgery, injury, or, most often, intercurrent infection. This can help slow down breakdown of protein from the body. Clues and challenges in the diagnosis of intermittent maple syrup urine disease. Treatment consists of dietary restriction of BCAAs and close metabolic monitoring. Metabolic disorders are conditions in which your body can’t function normally because it can’t properly convert food to energy to keep your body healthy. We review this disorder including its presentation, screening and clinical diagnosis, treatment, and other relevant aspects pertaining to the care of patients. Maple syrup urine disease (MSUD) is a life-threatening metabolic disorder.
