The auditory brainstem implant (ABI) was first developed nearly 40 years ago and provides auditory rehabilitation to patients who are deaf and ineligible for cochlear implant surgery due to abnormalities of the cochlea and cochlear nerve. The aims of the following review are to describe the history of the ABI and innovations leading up to the modern ABI system, as well as highlight areas of future development in implant design.

Neurofibromatosis type 2 (NF-2) is an autosomal dominant inherited disease caused by heterozygous mutations in the NF-2 tumor suppressor gene. It is characterized by the development of multiple benign tumors in the central nervous system. A majority of these tumors can be treated with surgery or radiotherapy in the case of the symptomatic disease. Read More

Introduction: Pediatric schwannomas are rare, and most of them are associated with neurofibromatosis type 2 (NF2) and usually located in the vestibular nerve. Herein, we present the first pediatric case of intracranial schwannoma derived from the IX/X nerve complex unrelated to NF2.

Hypothesis: We hypothesize that genomic variants including deletions, insertions, inversions, and tandem duplications beyond the changes in tumor suppressor NF2 gene affect gene expression of tumor-specific pathways in vestibular schwannomas (VS) patients with Neurofibromatosis type 2 (NF2), thus contributing to their clinical behavior.

Background: Genomic variation could reconfigure transcription in NF2 transformation process. Therefore, genome-wide high-resolution characterization of structural variants (SV) landscapes in NF2 tumors can expand our understanding of the genes regulating the clinical phenotypes in NF2-associated VS.

Schwannomas are peripheral nerve sheath tumors associated with three genetically distinct disease entities, namely sporadic schwannoma, neurofibromatosis type-2, and schwannomatosis. Schwannomas are associated with severe disability and in cases lead to death. The primary treatment is operative resection that itself can cause neurologic damage and is at times contra-indicated due to tumor location. Read More

Background: Neurofibromatosis type 2 (NF2) is a genetic tumor-predisposition disorder caused by NF2/merlin tumor suppressor gene inactivation. The hallmark of NF2 is formation of bilateral vestibular schwannomas (VS). Because merlin modulates activity of the Ras/Raf/MEK/ERK pathway, we investigated repurposing drugs targeting MEK1/2 as a treatment for NF2-associated schwannomas. Read More

Purpose: We have evaluated deficiencies in existing diagnostic criteria for neurofibromatosis 2 (NF2).

Methods: Two large databases of individuals fulfilling NF2 criteria (n = 1361) and those tested for NF2 variants with criteria short of diagnosis (n = 1416) were interrogated. We assessed the proportions meeting each diagnostic criterion with constitutional or mosaic NF2 variants and the positive predictive value (PPV) with regard to definite diagnosis. Read More

Neurofibromatosis is a neurocutaneous, tumor predisposing, inheritable disorder characterized by tumors of the brain and spine and the presence of skin lesions. The most important tumors associated with neurofibromatosis are vestibular nerve schwannomas, with others being meningiomas and ependymomas. The cord is also affected by tumors, ependymoma being the commonest, besides meningiomas and schwannomas. Read More

Malignant peripheral nerve sheath tumor (MPNST) is a rare soft-tissue sarcoma with an unfavorable prognosis and limited therapeutic options. MPNSTs can be sporadic, but are often associated with neurofibromatosis (NF) 1 and usually arise from preexisting neurofibromas. MPNSTs in patients with NF2 have been reported in only exceedingly rare cases, and the mechanisms underlying transformation into an MPNST have not been fully elucidated. Read More

Current consensus on optimal treatment of vestibular schwannoma remains poorly established; treatment options include observation, stereotactic radiosurgery, microsurgical resection, medical therapy, or a combination of these. Treatment should be individualized and incorporate the multitude of patient- and tumor-specific characteristics known to affect outcome. Treatment paradigms for sporadic and neurofibromatosis type 2-related tumors are distinct and decision-making in neurofibromatosis type 2 is uniquely challenging. Read More

Schwannomas are common, highly morbid and medically untreatable tumors that can arise in patients with germ line as well as somatic mutations in neurofibromatosis type 2 (NF2). These mutations most commonly result in the loss of function of the NF2-encoded protein, Merlin. Little is known about how Merlin functions endogenously as a tumor suppressor and how its loss leads to oncogenic transformation in Schwann cells (SCs). Read More

Objectives/hypothesis: Unilateral vestibular schwannoma (VS) occurs with a lifetime risk of around 1 in 1,000 and is due to inactivation of the NF2 gene, either somatically or from a constitutional mutation. It has been postulated that familial occurrence of unilateral VS occurs more frequently than by chance, but no causal mechanism has been confirmed.

The main manifestation of neurofibromatosis type 2 (NF2) is the development of bilateral vestibular schwannomas (VS). Consequently, one of the most severe functional sequelae is bilateral sensorineural hearing loss, caused by spontaneous tumor progression and/or treatment-related damage (surgery or radiosurgery). Preserving or restoring hearing is still challenging in NF2 no matter the strategy applied to each individual based on the natural history of VS. Read More

Neurofibromatosis type 2 (NF-2) is associated with mainly three types of recurrent benign tumors restricted to the central nervous system: schwannoma, meningioma and ependymoma. The absence of the protein NF2/Merlin causes an uninterrupted cell proliferation cascade originating from an abnormal interaction between an extracellular mucopolysaccharide, hyaluronan (HA), and schwann cell surface CD44 receptor, which has been identified as one of the central causative factors for schwannoma. Most tumors in NF-2 have a predilection to originate from either arachnoid cap cells or schwann cells of the cisternal portion of nerve rootlets that share a continuous exposure to cerebrospinal fluid (CSF).

The architectural and biochemical features of the plasma membrane are governed by its intimate association with the underlying cortical cytoskeleton. The neurofibromatosis type 2 (NF2) tumor suppressor merlin and closely related membrane:cytoskeleton-linking protein ezrin organize the membrane:cytoskeleton interface, a critical cellular compartment that both regulates and is regulated by growth factor receptors. An example of this poorly understood interrelationship is macropinocytosis, an ancient process of nutrient uptake and membrane remodeling that can both be triggered by growth factors and manage receptor availability.

Neurofibromatosis type 2 (NF2) syndrome is a very rare human genetic disease, and there has been no proper treatment for it until now. In our recent study, it has been reported that the loss of NF2 activates MAPK signaling through reduction of RKIP in a mesothelioma model. Here, we show that loss of NF2 induces reduction of the TGFβ receptor 2 (TβR2) expression, and an overwhelming expression of TGFβ receptor 1 (TβR1) is activated by physical stimuli such as pressure or heavy materials.
