Long‐Term Cochlear Implant Sensitivity in Patients With Far Advanced Otosclerosis

The Laryngoscope, EarlyView.
This study aimed to evaluate mid‐ and long‐term cochlear implant fitting in otosclerosis patients compared to a control group. It suggested significant tissue remodeling at the cochlear apex in otosclerosis patients, likely increasing resistance to electrical currents delivered by the implant.

Koos Classification of Vestibular Schwannoma via Image Translation-Based Unsupervised Cross-Modality Domain Adaptation [PDF]

arXiv, 2023
The Koos grading scale is a classification system for vestibular schwannoma (VS) used to characterize the tumor and its effects on adjacent brain structures. The Koos classification captures many of the characteristics of treatment deci-sions and is often used to determine treatment plans.

Malignant Rhabdoid Tumors of Cranial Nerves—A Clinically Distinct Group With Characteristic Neuroradiological, Histopathological, and Molecular Features

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Malignant rhabdoid tumors occasionally develop along cranial nerves, but clinical, histopathological, and molecular features have not been examined in larger series. Procedure We retrospectively interrogated data from the European Rhabdoid Registry, EU‐RHAB, to identify malignant rhabdoid tumors affecting cranial nerves.

Retroperitoneal schwannoma [PDF]

Journal of Surgical Case Reports, 2011
Retroperitoneal schwannomas are rare tumors and a correct pre-operative diagnosis is often not possible. They are usually identified incidentally via cross-sectional imaging. Diagnosis is based on histopathologic examination and immunohistochemistry. A 57-year-old man with a retroperitoneal schwannoma, as an unusual localisation, is presented.

MS-MT: Multi-Scale Mean Teacher with Contrastive Unpaired Translation for Cross-Modality Vestibular Schwannoma and Cochlea Segmentation [PDF]

arXiv, 2023
Domain shift has been a long-standing issue for medical image segmentation. Recently, unsupervised domain adaptation (UDA) methods have achieved promising cross-modality segmentation performance by distilling knowledge from a label-rich source domain to a target domain without labels.

Smart Temperature‐Sensitive Injectable Methylcellulose‐Based Hydrogels: Design and Optimization for Sustained Drug Release

VIEW, EarlyView.
MC‐based thermoreversible hydrogels were prepared and characterized. The MC/PEG hydrogel demonstrated sustained release of Dox, with rapid gelation time and the feasibility of controlling the drug release rate with temperature changes. Wide‐spectrum biocompatibility of the MC/PEG hydrogel was demonstrated, along with its ability to significantly reduce

Schwannoma of the tongue [PDF]

BMJ Case Reports, 2016
Schwannoma, neurilemmoma or neurinoma is a rare, benign nerve sheath neoplasm composed of Schwann cells. It is usually solitary, slow growing and asymptomatic. Approximately 1–12% of the tumours occur intraorally with the tongue being the most common location. We report a rare case of lingual schwannoma in a 20-year-old female patient involving the tip

Biphenotypic Sinonasal Sarcoma-Case Report and Review of Clinicopathological Features and Diagnostic Modalities. [PDF]

, 2019
Background Biphenotypic sinonasal sarcoma is a recently described malignancy showing dual differentiation with both myogenic and neural elements. Due to its histologic similarities to other sinonasal malignancies, it is a diagnostic challenge.

A Solitary Malignant Schwannoma in the Choana and Nasal Septum

Case Reports in Otolaryngology, 2014
Malignant schwannoma is an extremely rare tumor and the risk of malignant schwannoma increases in patients with von Recklinghausen’s disease. Recently, we encountered a case of solitary malignant schwannoma in the choana and posterior nasal septum ...

Unusually large quiescent ancient schwannoma of hypoglossal nerve

Indian Journal of Dental Research, 2013
Ancient schwannoma is considered as a variant of schwannoma, comprising about 10% of all schwanommas. Schwannoma is a benign neoplasm derived from the nerve sheath of peripheral motor, sensory and sympathetic nerves and from the cranial nerve pairs.
