OBJECT The incidence of syringomyelia in patients with Chiari I malformation is reported to be between 20 and 75%. In the series reported herein 10.6% of patients with both clinical entities have continued to have a significant syrinx following their first decompressive procedure. All but one patient had resolution of their syrinx after a second posterior(More)
OBJECTIVE Some have proposed that the calvarial thickening seen in patients with rickets results in an increased rate of Chiari I malformation (CIM) in these patients. The present study measures the posterior fossa volume in children with rickets to verify previous case reports indicting a small posterior fossa as the cause for an increased rate of CIM in(More)
OBJECTIVE AND IMPORTANCE The expected time interval for resolution of hydromyelia after Chiari I decompression is lacking in the literature. This case report highlights one instance of delayed resolution of Chiari-induced hydromyelia. CLINICAL PRESENTATION We report an adolescent girl with a Chiari I malformation and hydromyelia. INTERVENTION A(More)
OBJECT The authors hypothesized that children with preoperative Chiari I malformation and an absent gag reflex may harbor pharyngeal musculature atrophy identifiable on magnetic resonance (MR) imaging. METHODS Thirty patients with preoperative Chiari I malformation and a functioning gag reflex, five patients with preoperative Chiari I malformation and(More)
1. The bipyridilium herbicides, particularly paraquat, have chemical and toxicological features in common with the bi-quaternary ammonium ganglion blockers. 2. Paraquat and diquat were tested for ganglion blocking activity. Rabbit cervical ganglia were superfused with both agents and subsequently with hexamethonium to confirm susceptibility to ganglion(More)
