Ventriculoperitoneal shunt placement for the treatment of hydrocephalus is one of the most common pediatric neurosurgical procedures. Complications, including infections, catheter obstruction, shunt breakdown, and hemorrhage, have been described in the literature.

New proteins configure a brain drug resistance map in tuberous sclerosis.

Epileptogenic cortical tubers, characterized by dysplastic neurons and balloon cells, is a frequent feature of tuberous sclerosis. In severe tuberous sclerosis-affected individuals, seizures are refractory to medication. Multidrug resistance proteins (multidrug resistance protein-1 [MDR-1] and multidrug resistance-associated protein-1 [MRP-1]) have been found to be highly expressed in epileptogenic cortical tubers.
