Diffusion tensor magnetic resonance imaging for predicting the consistency of intracranial meningiomas.
The ability of preoperative MRI-sequences to predict the consistency of intracranial meningiomas has not yet been clearly defined. We aim to demonstrate that diffusion tensor imaging (DTI) improves the prediction of intracranial meningiomas consistency. ⋯ FA value and MD and FA maps are useful for prediction of meningioma consistency and, therefore, may be considered in the preoperative routine MRI examination of all patients with intracranial meningiomas.

Peripheral nerve stimulation by 'sandwich' paddle leads: technical note.
Recently, there has been a burgeoning interest in the utility of peripheral nerve stimulation (PNS) for a variety of chronic focal neuropathic, musculoskeletal and visceral pain conditions. If the source of pain is directly related to a single peripheral nerve, surgical exposure and placing a paddle lead on the nerve are most effective. ⋯ In selected cases where an open surgical PNS lead needs to be placed, the 'sandwich' technique can be used to augment the stimulation without additional morbidity. Although occasionally used in practice, this technique is still unreported.

Extended endoscopic endonasal approach for recurrent or residual adult craniopharyngiomas.
The aim of this study was to evaluate the effectiveness of the extended endoscopic endonasal transsphenoidal approach (TSA) for recurrent or residual craniopharyngiomas, focusing on the extent of tumor resection and complications resulting from surgery at a single institution. ⋯ The extended endoscopic endonasal transsphenoidal approach is an effective and safe surgical approach for treating recurrent or residual craniopharyngioma.

Neurolysis for secondary sciatic nerve entrapment: evaluation of surgical feasibility and functional outcome.
The study included 11 patients; seven males and four females with mean age of 68.3 ±11 years. All patients had sciatic nerve entrapment: three had a penetrating injury, three suffered postoperative trauma, two had a crush injury, two had inadvertent injections and one was trapped in a machine belt. Clinical examination included: an evaluation of the extent of motor and sensory impacts according to the British Medical Research Council (BMRC) scale and the Semmes-Weinstein monofilament test; assessment of pain sensation using the visual analogue scale (VAS); electromyography; and nerve conduction velocitiey determination. The applied operative procedure for sciatic neurolysis was modulated according to the suspected site of sciatic nerve entrapment. At 6 and 12 months after surgery all patients were evaluated for recovery of motor and sensory function. ⋯ Surgical exploration and neurolysis of cases with sciatic nerve entrapment is a safe and effective therapeutic modality with significant improvement of both motor and sensory functions without risk of additional deficit secondary to neurolysis.
