Randomized Controlled Trial Comparative Study
Early versus delayed endoscopic surgery for carpal tunnel syndrome: prospective randomized study.
To compare the effects of early versus delayed endoscopic surgery in patients with moderately severe carpal tunnel syndrome (CTS). ⋯ On the basis of this study, early endoscopic surgery is proposed in patients with moderately severe CTS.

Comparative Study Controlled Clinical Trial
Acute normovolemic hemodilution is safe in neurosurgery.
To determine the safety of acute normovolemic hemodilution (ANH) for patients undergoing neurosurgical procedures. ⋯ ANH is a safe procedure for patients undergoing neurosurgical procedures. Further studies are necessary to confirm the improvement in brain oxygen extraction and the clinical impact. Nonetheless, patients undergoing aneurysm clipping with good clinical grades seem to profit from ANH.

Review
The nervus intermedius: a review of its anatomy, function, pathology, and role in neurosurgery.
Geniculate neuralgia, although uncommon, can be a debilitating pathology. Unfortunately, a thorough review of this pain syndrome and the clinical anatomy, function, and pathology of its most commonly associated nerve, the nervus intermedius, is lacking in the literature. Therefore, the present study aimed to further elucidate the diagnosis of this pain syndrome and its surgical treatment based on a review of the literature. ⋯ Neuralgia involving the nervus intermedius is uncommon, but when present, can be life altering. Microvascular decompression may be effective as a treatment. Along its cisternal course, the nerve may be difficult to distinguish from the facial nerve. Based on case reports and small series, long-term pain control can be seen after nerve sectioning or microvascular decompression, but no prospective studies exist. Such studies are now necessary to shed light on the efficacy of surgical treatment of nervus intermedius neuralgia.

Case Reports
Traumatic (type II) odontoid fracture with transverse atlantal ligament injury: a controversial event.
Traumatic (Type II) odontoid fractures are very common injuries. Nevertheless, their connection with transverse atlantal ligament injury is controversial and poorly defined. The aim of this study is to report a single case of traumatic (type II) odontoid fracture with transverse atlantal ligament injury and to critically analyze the role of ligaments and membranes together with neuroradiological tools in the management of craniovertebral junction-traumatized patients. ⋯ Traumatic (type II) odontoid fracture with transverse atlantal ligament avulsion can be considered an unusual event. It is our opinion that the routine use of MRI for all patients with type II odontoid fracture could be unjustified in clinical practice. Strict clinical surveillance of all patients managed conservatively and the use of MRI in selected cases could be a reasonable management option.

Case Reports
Multimodal treatment of hemorrhagic pituitary metastasis as first manifestation of renal cell carcinoma.
Metastatic tumors involving the pituitary gland are very rare, with only few cases reported so far in the literature. ⋯ This is the first report describing multimodality treatment of a patient with pituitary metastasis of unknown origin requiring presurgical embolization before successful tumor removal.
