Review Case ReportsCavernous malformations isolated from cranial nerves: Unexpected diagnosis?
Cranial nerves (CN) cavernous malformations (CMs) are lesions that are isolated from the CNs. The authors present three cases of CN CMs, for which MR was demonstrated to be critical for management, and surgical resection produced good outcomes for the patients. Surgical removal is the recommended course of action to restore or preserve neurological function and to eliminate the risk of future haemorrhage. However, the anatomical location and the complexity of nearby neural structures can make these lesions difficult to access and remove. In this study, the authors review the literature of reported cases of CN CMs to analyse the clinical and radiographic presentations, surgical approaches and neurological outcomes. ⋯ CN CMs present with specific symptoms and require complex surgical techniques for resection. These lesions are frequently symptomatic, because of the complexity of the origin tissue. Symptomatic CN CMs should be resected microsurgically and completely when possible to prevent further losses of nerve function, improve function, avoid recurrence, and to eliminate the risk of future haemorrhages. The authors discuss the therapeutic options and the radiological features of these infrequent localisation of CMs. Specifically, the authors focus on the role of magnetic resonance imaging in the identification of these rare lesions.

Review Case ReportsTherapeutic hypothermia for status epilepticus: A report, historical perspective, and review.
Refractory status epilepticus is a disease associated with high morbidity and mortality, which does not always respond to standard treatments, and when they fail, alternative modalities become crucial. Therapeutic hypothermia slows nerve conduction in vitro, and has been shown to abort seizures in animal models. ⋯ We report a case of super-refractory status epilepticus successfully treated with therapeutic hypothermia, complimented by a historical and literature review of this modality. While there is limited evidence, and some risks associated with therapeutic hypothermia, it should be considered as a reasonable and potentially effective treatment option for refractory status epilepticus.

Evaluation of endoscopic dorsal ramus rhizotomy in managing facetogenic chronic low back pain.
To study the effectiveness of surgical dorsal endoscopic rhizotomy for the treatment of facetogenic chronic low back pain. ⋯ Dorsal endoscopic rhizotomy is safe and effective for the facetogenic CLBP, and can achieve better clinical outcome than the conservative treatment.

Long-term outcomes of bilateral pallidal stimulation for primary generalised dystonia.
Bilateral pallidal stimulation is an established surgical management for patients with primary generalised dystonia (PGD). The aim of this study was to present our long-term experience of bilateral pallidal stimulation in patients with PGD. ⋯ Our results indicate that bilateral pallidal stimulation is an effective treatment for patients with DYT-1 positive and DYT-1 negative PGD. The most common hardware-related complication (DBS lead breakage) in our series was associated with the slippage of the connector to the cervical area. To prevent this complication after changing the surgical technique (suturing and placing the connector in parietal region) we did not observe these complications. Unilateral IPG failure resulted in the development of severe status dystonicus.

Case ReportsTrue aneurysms of the superficial temporal artery: Diagnosis and treatment.
True aneurysms arising from the superficial temporal artery (STA) are quite uncommon. The present study reviews the surgical experience with true STA aneurysms to describe the clinical features and treatment options. ⋯ True STA aneurysms are usually discovered as a pulsating mass over the temple and their diagnosis could be done with ultrasonography, and computed tomography and magnetic resonance angiography. Simple ligation and resection of the aneurysm is safe and curative.
