Endoscopic management of supratentorial ventricular neurocysticercosis: case series and review of the literature.

Objective: Despite the increasing popularity of neuroendoscopy, scarce documentation exists in the literature regarding successes and failures of this treatment modality for ventricular cysticercosis. Since July 2000, we instituted a specific endoscopic strategy for select patients with supratentorial ventricular disease. The goals of the strategy were to 1) remove ventricular cysts; 2) employ internal CSF diversion procedures for hydrocephalus to avoid shunting, and; 3) elude open surgical procedures.

Recurrent (nonfamilial) hemangioblastomas involving spinal nerve roots: case report.

Objective And Importance: Spinal nerve root hemangioblastomas are rare and are reported mainly in patients with von Hippel-Lindau (VHL) syndrome. The pathogenesis of so-called nonfamilial lesions is virtually unknown. We discuss, mainly from a molecular perspective, a unique patient with sporadic, recurrent hemangioblastomas restricted to spinal nerve roots.

The lack of effect of aerobic exercise training on propranolol pharmacokinetics in young and elderly adults.

The effects of exercise training on the pharmacokinetics of orally administered propranolol were studied in young and elderly healthy volunteers. Twenty-three young (30 +/- 5 years of age) and 20 elderly (67 +/- 5 years of age) adults were randomly assigned to endurance training (N = 12 young subjects, 10 elderly subjects) or nonexercising control (N = 11 young subjects, 10 elderly subjects) groups. Training consisted of treadmill walking, stair climbing, or both three times per week for 40 minutes at 70-85% of maximal heart rate reserve for 16 weeks.

Nasal mucociliary clearance after radiation therapy.

Irradiation has been demonstrated to cause decreased mucociliary clearance in animal models. We sought to verify this effect clinically by using the saccharin transport test to evaluate nasal mucociliary clearance in 9 patients previously treated with radiation therapy to the nasal cavity. The patients also completed a questionnaire examining the prevalence of nasal symptoms before and after radiation therapy.
