Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM study on COVID-19.

Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens.

Postoperative Textiloma Mimicking Intracranial Rebleeding in a Patient with Spontaneous Hemorrhage: Case Report and Review of the Literature.

During craniotomy, hemostatic materials such as oxidized cellulose and cotton pads, commonly used to control bleeding, may cause a granulomatous reaction that may produce space-occupying mass lesions termed textiloma (or gossypiboma). We present a 46-year-old female who underwent a right frontotemporal craniotomy and surgical removal of intraparenchymal cerebral hemorrhage, and who developed a textiloma during the postoperative period causing seizures. Granulomatous reactions due to hemostatic agents have been reported experimentally, as well as after cranial and spinal operations.

Glioblastoma Multiforme and Genetic Mutations: The Issue Is Not Over Yet. An Overview of the Current Literature.

Background And Objective:  Glioblastoma multiforme (GBM) is still a deadly disease with a poor prognosis and high mortality, despite the discovery of new biomarkers and new innovative targeted therapies. The role of genetic mutations in GBM is still not at all clear; however, molecular markers are an integral part of tumor assessment in modern neuro-oncology.

Material And Methods:  We performed a Medline search for the key words "glioblastoma," "glioblastoma multiforme," and "genetic" or "genetics" from 1990 to the present, finding an exponential increase in the number of published articles, especially in the past 7 years.

The Y-shaped trabecular bone structure in the odontoid process of the axis: a CT scan study in 54 healthy subjects and biomechanical considerations.

Objective: Odontoid process fractures are very common in both young and geriatric patients. The axial trabecular architecture of the dens appears to be crucial for physiological and biomechanical function of the C1-2 joint. The aim of this study is to demonstrate the presence of a Y-shaped trabecular structure of the dens on axial CT and to describe its anatomical and biomechanical implications.

Falcine meningioma in Von Hippel-Lindau disease: An unusual association.

Background: Von Hippel-Lindau (VHL) disease is an autosomal dominant condition characterized by formation of multiple benign and malignant tumors. In this disease supratentorial lesions are rare and no falcine meningioma has been previously reported. Differential diagnosis is very difficult and the histopathological examination is the definitive method for diagnosis.

Surgical case series of multiple aneurysms: A single-centre experience of 16 years.

Introduction: Multiple aneurysms are present in 10% in patients with intracranial aneurysms. An analysis of the literature, focusing on the different treatments, and a description of our experience are performed.

Presentation Of Case Series: A surgical series with multiple intracranial aneurysms from 2000 to 2016, describing demographic, radiological and clinical features, is showed.

Acute onset of paraganglioma of filum terminale: A case report and surgical treatment.

Introduction: Paragangliomas of filum terminale are rare benign tumors, arising from the adrenal medulla or extra-adrenal paraganglia. These lesions usually present with chronic back pain and radiculopathy and only two cases of acute neurological deficit have been reported in literature.

Presentation Of Case: A case with an acute paraplegia and cauda equina syndrome due to an hemorrhagic paraganglioma of the filum terminale is described.
