Effectiveness of lumbar zygapophysial joint blockage for low back pain.
Zygapophysial joints have been a well-recognized source of low back pain. This paper compares the efficacy of lumbar zygapophysial joints blockage and medical therapy in terms of pain relief, loss of working days and recurrence of pain in a population with mechanical low back pain. ⋯ Blockage of the lumbar facet joints is a rapid and effective way to reduce pain originating from lumbar facet joints.

Clinical Trial
Correlation of pulsatility index with intracranial pressure in traumatic brain injury.
In traumatic brain injury (TBI) patients, it is desired to monitor the intracranial pressure (ICP) to assess the cerebral haemodynamics and guide the therapy. The study was designed to see if the pulsatility index (PI) measured by transcranial Doppler ultrasonography (TCD) predicts information about ICP values. ⋯ The strong correlation observed between ICP and PI through the management period of TBI patients can lead us to use TCD ultrasonography-derived PI as a guide if invasive monitoring is not available.

The sitting position is routinely used in many centers, although its use remains controversial and appears to be diminishing because of the risk of venous air embolism (VAE). ⋯ The study provides a significant body of data on neuroanesthesia for the sitting position and our results suggest that if the sitting position is a neurosurgical necessity it can be used with vigilant follow up throughout the procedure to detect any occurrence of VAE by ETCO2 monitoring if you do not have the chance to use more sensitive tools.

To assess the long-term outcomes of percutaneous retrogasserian glycerol rhizotomy (PRGR) in patients with medically unresponsive idiopathic trigeminal neuralgia. ⋯ PRGR is a minimally invasive and simple procedure yielding a favorable outcome for trigeminal neuralgia. The major complications of this procedure are reversible within various time intervals. It may serve as a first-line surgical modality for patients unresponsive to pharmacotherapy.

Medulloblastoma is the most common malignant tumor of childhood and usually arises from the cerebellar vermis. Several histological types of medulloblastoma have been described. Myogenic and melanotic differentiated medulloblastoma are seldom seen. ⋯ According to our knowledge there are six cases reported in the literature so far. Oncogenic factors in medulloblastoma development are controversial. Presence of multiple differentiation patterns supports a pluripotent origin for these tumors.
