A 14-year-old male is referred to the neurology clinic by his PCP with the complaint of bilateral hearing loss. Neurological examination shows a sensorineural hearing loss. Multiple hyperpigmented lesions on the chest and back were also appreciated. An MRI of the brain was ordered that showed bilateral posterior fossa lesions. Genetic testing would reveal a mutation on which chromosome?

After several months, she begins to experience paresthesias in her legs and has several falls. She is referred to a neurologist. On examination, she is noted to have non-length-dependent severe loss of vibration sensation in her legs, loss of pain and temperature distally in a length-dependent pattern, and spastic tone with hyperreflexia in her lower extremities. Additionally, her gait is wide-based and a Romberg’s sign is positive. Which of the following treatments is most likely to prevent further neurologic deterioration?

A 9-year-old boy with no significant past medical history was referred to get an EEG because of declining school performance and concern for staring vs. daydreaming episodes.
