Identifying metabolic shifts in Crohn's disease using' omics-driven contextualized computational metabolic network models.

Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. A clear gap in our existing CD diagnostics and current disease management approaches is the lack of highly specific biomarkers that can be used to streamline or personalize disease management. Comprehensive profiling of metabolites holds promise; however, these high-dimensional profiles need to be reduced to have relevance in the context of CD.

Hannover Classification of Vestibular Schwannomas: A Reliability Study.

Background: The Hannover classification of vestibular schwannomas is designed to stratify tumors based on extrameatal extension and compression of the brainstem. We have previously reported the reliability of the Koos system, but to date, no study has assessed the reliability of the similar Hannover classification.

Objective: We present an assessment of the intrarater and interrater reliability of the Hannover classification system.

Characterization of kindled VGAT-Cre mice as a new animal model of temporal lobe epilepsy.

Objective: Development of novel therapies for temporal lobe epilepsy is hindered by a lack of models suitable for drug screening. While testing the hypothesis that "inhibiting inhibitory neurons" was sufficient to induce seizures, it was discovered that a mild electrical kindling protocol of VGAT-Cre mice led to spontaneous motor and electrographic seizures. This study characterizes these seizures and investigates the mechanism.

Angiosarcoma of the Temporal Bone: Case Report and Review of the Literature.

Background: Angiosarcomas are rare malignant tumors of endothelial origin. Nearly one half of all angiosarcomas occur in the head and neck. Temporal bone angiosarcomas are extremely uncommon.

Chondroblastoma-like mass of the temporal bone, secondary aneurysmal bone cyst, and intracerebral hemorrhage in a patient with cardiofaciocutaneous syndrome: case report.

Cardiofaciocutaneous syndrome (CFCS) is a rare developmental disorder that is phenotypically similar to Noonan syndrome and is associated with mutations in BRAF, MEK1, MEK2, and KRAS. The relationship between malignancy risk and CFCS is unclear with few cases published in the literature. The purpose of this paper is to describe the case of a patient with CFCS presenting in extremis as a result of a large intracerebral hemorrhage arising from a temporal bone mass with histopathology most consistent with chondroblastoma and secondary aneurysmal bone cyst.
