Removal of Koos IV acoustic neuroma and auditory brainstem implant in NF2 patient.

The authors present the case of removal of a Koos grade IV right acoustic neuroma in a neurofibromatosis type 2 (NF2) patient, already operated on for left cerebellopontine angle meningioma at 7 years of age and a left acoustic neuroma at 16 years of age. A transpetrosal approach allowed cochlear sensor implantation to detect residual hearing. An enlarged retrosigmoid approach then allowed subtotal microsurgical removal of the lesion; consequently, the authors illustrate the technical nuances of an auditory brainstem implant (ABI).

Accurate Energy Modeling and Characterization of IEEE 802.11ah RAW and TWT.

Minimizing the energy consumption is one of the main challenges in iot networks. Recently, the IEEE 802.11ah standard has been released as a new low-power Wi-Fi solution.

Surgical treatment of thalamic tumors in children.

OBJECTIVE In the past, the outcome of surgical treatment for thalamic tumor was poor. These lesions were often considered inoperable. However, contemporary microsurgical techniques, together with improvements in neuroimaging that enable accurate presurgical planning, allow resection to be accomplished in a safer way.

A new schedule of fotemustine in temozolomide-pretreated patients with relapsing glioblastoma.

In the present study we investigated the feasibility and effectiveness of a new biweekly schedule of fotemustine (FTM) in patients with recurrent glioblastoma, after at least one previous treatment. The primary endpoint was progression-free survival at 6 months; secondary objectives were clinical response, overall survival, disease-free survival, and toxicity. Forty patients (median age 52.
