The aim of this study was to investigate the feasibility and effectiveness of endoscopic neurosurgery for patients with third ventricular colloid cysts but without ventriculomegaly. ⋯ Endoscopic resection of third ventricular colloid cyst in patients without hydrocephalus seems to be feasible, effective, and not contraindicated.

A hollow brain model was created using soft urethane. A tube passing through the hollow was attached for use as a water inlet and manometer. Water sufficient in quantity to realize the intended initial pressure was infused through the tube. ⋯ At the same time, the water column of the manometer was measured and the relationship with the force of the brain spatula was investigated. A positive correlation between the water column and local force was confirmed. This indicated that it was possible to use this model without a force sensor for the same training using water column measurements.

To report five patients who underwent lumbopleural (LPl) shunting for the treatment of idiopathic intracranial hypertension (IIH) and to describe the considerations, complications, and outcomes related to this rarely described procedure. ⋯ LPl shunting, though rarely used, is a viable option in the treatment of IIH refractory to standard peritoneal shunting. When pursuing this treatment, a valve and ASD are recommended to mitigate the risks of overdrainage and pleural effusion. Chest imaging should be obtained if the patient becomes symptomatic but can be deferred if the patient remains asymptomatic and is doing well.

Neuronavigation is an essential tool in cranial neurosurgery. Despite continuing improvements in the technologies used for neuronavigation, certain events can lead to unacceptable mismatches. To provide the best possible outcome for the patients, surgeons need to do everything possible to reduce mismatches. ⋯ Both techniques are easy to use, do not require expensive additional instruments, and are helpful in procedures involving neuronavigation.

The influence of cultured Schwann cells on injured spinal cord in rats is examined. ⋯ The data show that activated Schwann cells are able to induce the repair of injured spinal cord white matter. The route of application of cells via the cisterna magna seemed to be useful for their delivery in spinal cord injury therapy.
