Blindness, deafness, quadriparesis, and a retinal malformation: the ravages of neurofibromatosis 2.
Advances in molecular biology have established that the diseases once collectively referred to as neurofibromatosis are actually genetically distinct and clinically heterogenous conditions. This realization has led to separate definitions for neurofibromatosis (NF) type 1 and 2. Although ophthalmologic manifestations of NF1 have long been recognized, the distinguishing ocular features of NF2 have only recently received attention. We describe an inferior retinopapillary malformation with an overlying glial hamartoma in a deaf, quadriparetic patient with NF2. Magnetic resonance (MR) imaging initially showed bilateral vestibular schwannomas and a large cervical ependymoma. Over six years of follow-up, the patient developed multiple intracranial meningiomas.

Status dystonicus and Hallervorden-Spatz disease: treatment with intrathecal baclofen and pallidotomy.
Severe dystonia or status dystonicus is a life threatening disorder that develops in patients with both primary and secondary dystonia. We present the case of a 9-year-old boy with Hallervorden-Spatz disease (HVS) who developed status dystonicus, failing to respond to high dose oral therapy with multiple antidystonic agents. High dose intravenous sedating agents combined with endotracheal intubation and mechanical ventilation were required to control the spasms. Alleviation of the spasms was achieved by a combination of temporary intrathecal baclofen infusions and bilateral pallidotomy. Although it could be argued this is a situation where only palliative measures should be used, we believe a relatively aggressive approach was justified. It relieved the intense pain associated with the spasms and allowed the child to be discharged home without the prolonged stay in intensive care, morbidity and mortality, which characterize status dystonicus.
