Posterior fossa arteriovenous malformations

Neurosurgical Focus, 2009
Arteriovenous malformations (AVMs) of the posterior fossa are complex neurovascular lesions that are less common than their supratentorial counterparts, accounting for < 15% of all AVMs. The majority of patients with these lesions present with intracranial hemorrhage, a factor that has been consistently shown to increase one's risk for subsequent ...

Clinical and Molecular Characterization of 46 Patients With Beckwith–Wiedemann Spectrum and Uniparental Disomy of 11p15

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Beckwith–Wiedemann spectrum (BWSp) is an overgrowth disorder characterized by its main clinical features macrosomia, macroglossia, and abdominal wall defects. BWSp is caused by (epi)genetic chromosome 11p15 alterations with approximately 20%–27% of patients exhibiting mosaic paternal uniparental disomy of chromosome 11p15 (pUPD11p15).

Expanding the Phenotypic Spectrum of TXNDC15‐Related Ciliopathies to Include Joubert Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic loss‐of‐function variants in TXNDC15 are a known cause of the perinatally lethal ciliopathy Meckel syndrome (MKS). TXNDC15 encodes an endoplasmic reticulum (ER)‐resident thioredoxin‐domain protein required for ciliary transition zone integrity.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Trigeminal neuralgia and posterior fossa meningioma: case report and review of literature

Egyptian Journal of Neurosurgery, 2019
Trigeminal neuralgia may be idiopathic or may involve other causes. It can be secondary to posterior fossa tumors many times. In the present case, posterior fossa meningioma was detected with trigeminal neuralgia together. However, relevant meningioma is

Complications and Clinical Outcomes Following Modified Endoscopic Denker's With Pyriform Aperture Preservation: A Prospective Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The modified endoscopic Denker's (MED) approach provides access to all maxillary sinus (MS) walls for resection of various MS and retromaxillary pathologies, but the anteromedial maxilla has historically been resected. This study determined complication rates and outcomes following MED with pyriform aperture (PA) preservation ...

Nanofabricated Biomaterials Model Tumor Extracellular Matrix Topography

Advanced NanoBiomed Research, EarlyView.
The unique structure and composition of the tumor microenvironment and its associated extracellular matrix (ECM) exert profound effects on cancer cell behavior that are difficult to model in vitro. This perspective discusses the utility of nanofabricated biosubstrates, such as the novel collagen‐coated nanogrooved array, for recapitulating the ...
