Objective: Advancements in microsurgical technique and technology continue to improve outcomes in patients with skull base tumor. The primary cranial nerve eight monitoring systems used in hearing preservation surgery for vestibular schwannomas (VSs) are direct cranial nerve eight monitoring (DCNEM) and auditory brainstem response (ABR), although current guidelines are unable to definitively recommend one over the other due to limited literature on the topic. Thus, further research is needed to determine the utility of DCNEM and ABR.

Study Design: This study is retrospective prospective. Qualifying patients were identified and administered Penn Acoustic Neuroma Quality-of-Life (PANQOL) Scale.
Background: Intrathecal baclofen (ITB) is a treatment modality used to improve the quality of life of patients with intractable spasticity and dystonia. Although it is an effective solution in patients failing oral interventions, it is associated with potential infectious complications. It is known that pediatric patients with ITB have significantly higher infection rates compared with adult patients.

Currently, there are limited evidences to show an increased risk of infection or increased mortality among pregnant women than the general population. On the 13th of March 2020, Ethiopian government reported the first case of COVID-19.

We aimed to test the feasibility of hypermethylated () detected in circulating cell-free DNA as a non-invasive diagnostic marker of testicular germ cell tumors, combined with miR-371a-3p.

We describe geographic origins and characteristics associated with successful match into US neurosurgery training programs.
Methods: Retrospective review of AANS membership data (2007-2017).
Posterior vault distraction osteogenesis (DO) is an emerging treatment option for craniosynostosis. Operative nuances detailing surgical management are being described with increasing use and experience. In this article, we discuss the surgical management of an 8-month-old male with a ventriculoperitoneal shunt (VPS) diagnosed with bilateral lambdoid craniosynostosis and Chiari I malformation.
View Article and Find Full Text PDFTenosynovial giant cell tumor (TGCT) is a rare entity that is not well described in the neurosurgical literature. We present a case of a 37-year-old woman with a diffuse subtype TGCT of the cervical spine, affecting the left cervical 6-7 facet joint, with co-incidental cervical trauma. Initial management consisted of subtotal resection and cervical stabilization with cervical 6 to 7 laminectomy, and cervical 4 to thoracic 2 posterior instrumented fusion.

We present a predictive model that uses the clival length and ethmoidal width to predict the size and surgical freedom (SF) of these corridors. Adult facial computed tomography scans were reviewed.

We report a case of a patient with PAI-1 deficiency who presented with delayed spontaneous recurrence of an acute subdural hematoma (aSDH) after evacuation.
Case Description: A 29-year-old male presented with altered mental status (AMS) after a fall at a construction site with Glasgow Coma Scale (GCS 4T).
Glycerol rhizotomy was originally described as an initial surgical treatment for trigeminal neuralgia after the failure of medical therapy. Here we describe its use as a salvage procedure, typically after failure of multiple other modalities including microvascular decompression, stereotactic radiosurgery, and/or other percutaneous procedures. Foramen ovale cannulation as a "salvage procedure" may be complicated by lack of cerebrospinal fluid (CSF) return despite adequate cannulation of the foramen ovale, making conventional fluoroscopic confirmation of adequate needle placement less certain.

In this case report the authors report on the management of a giant PE extending through the floor of the middle fossa.An 8-month-old boy presented to the authors' service with a large PE projecting into his neck through a missing left middle fossa floor; the lesion was causing significant meta-, dys-, and hypoplasia of the structures of the anterolateral neck on that side.

Excessive consumption of such food often exceeds the normal requirement of the methionine in our body; which found to be related to the development of neurodegenerative disorders. However, the mechanistic pathways of methionine's influence on the brain are unclear.

Recent studies report Hcy to be a newly recognized risk factor for osteoporosis. Elevated Hcy levels are known to modulate osteoclastgenesis by causing detrimental effects on bone via oxidative stress induced metalloproteinase-mediated extracellular matrix degradation and decrease in bone blood flow.

Low birth weight (LBW) babies are significantly at risk of death, contributing to the high perinatal morbidity and mortality in developing countries. Hence, this study aims to assess the incidence and associated factors of low birth weight (LBW) in Gondar University Hospital deliveries.
