Long-term clinical outcomes of spinal accessory nerve transfer to the suprascapular nerve in patients with brachial plexus palsy.
For the reconstruction of brachial plexus lesions, restoration of elbow flexion and shoulder function is fundamental and is achieved by dual nerve transfers. Shoulder stabilization and movement are crucial in freedom of motion of the upper extremity. In patients with C5-C6 brachial plexus injury, spinal accessory nerve transfer to the suprascapular nerve and a fascicle of ulnar nerve to musculocutaneous nerve (dual nerve transfer) are carried out for restoration of shoulder abduction and elbow flexion, respectively. In the present study, we evaluated the long-term clinical outcomes of spinal accessory nerve transfer to the suprascapular nerve for restoration of shoulder abduction in patients with brachial plexus palsy undergoing a dual nerve transfer. ⋯ The evidence from the present study suggests that transferring spinal accessory nerve to the suprascapular nerve for restoring shoulder abduction is an effective and reliable treatment with high success rate in patients with brachial plexus palsy, especially in young patients.

Risk factors for post-operative respiratory failure among 94,621 neurosurgical patients from 2006 to 2013: a NSQIP analysis.
Post-operative respiratory failure can occur after neurosurgical operations. Identification of risk factors for respiratory failure after neurosurgery may help guide clinical decision-making, decrease length of stay, improve patient outcomes, and lower costs. ⋯ Based on the NSQIP database, risk factors for respiratory failure after neurosurgery include pre-operative ventilator dependence, alcohol use, functional dependence prior to surgery, stroke, and recent operation. The overall rate of respiratory failure decreased from 4.1 % in 2006 to 2.1 % in 2013 according to these data.

Subcutaneous trigeminal nerve field stimulation for refractory trigeminal pain: a cohort analysis.
Neurosurgical pain management of drug-resistant trigeminal neuralgia (TN) is highly challenging. Microvascular decompression is a first-line neurosurgical approach for classical TN with neurovascular conflict, but can show clinical relapse despite proper decompression. Second-line destructive techniques like radiofrequency thermocoagulation have become reluctantly used due to their potential for irreversible side effects. Subcutaneous peripheral nerve field stimulation (sPNFS) is a minimally invasive neuromodulatory technique which has been shown to be effective for chronic localised pain conditions. Reports on sPNFS for the treatment of trigeminal pain (sTNFS) are still sparse and primarily focused on pain intensity as outcome measure. Detailed data on the impact of sTNFS on attack frequency are currently not available. ⋯ Treatment by sTNFS is a beneficial option for patients with refractory trigeminal pain. Prospective randomised trials are required to systematically evaluate efficacy rates and safety of this low-invasive neurosurgical technique.

Case ReportsRadiosurgery for infundibulum adenoma: stalk dose implications.
Treating pituitary adenomas in the infundibulum with stereotactic radiosurgery (SRS), achieving tumor volume control while preserving pituitary endocrine function and visual function, is challenging. We present a case of a recurrent remnant infundibular lesion treated with Gamma Knife surgery (GKS). ⋯ Five years after GKS, tumor regression persists without visual dysfunction or hypopituitarism. Radiosurgical doses of 30 Gy to the pituitary stalk may be tolerated by patients while maintaining endocrine function.

The role of ICP monitoring in patients with persistent cerebrospinal fluid leak following spinal surgery: a case series.
Cerebrospinal fluid (CSF) leak following spinal surgery is a relatively common surgical complication. A disturbance in the underlying CSF dynamics could be the causative factor in a small group of patients with refractory CSF leaks that require multiple surgical repairs and prolonged hospital admission. ⋯ Abnormal cerebrospinal fluid dynamics could be the underlying factor in patients with a persistent and treatment-refractory CSF leak post spinal surgery. Treatments aimed at lowering ICP may be beneficial in this group of patients. Whether abnormal pressure and dynamics represent a pre-existing abnormality or is induced by spinal surgery should be a subject of further study.
