Article Type: Case Report | First Published: April 10, 2020
Pilocytic astrocytomas are tumors of the central nervous system mostly during the first two decades of life. Although they are mostly common in the midline structures of children, pilocytic astrocytoma within the ventricular system of an adult is rare. To our knowledge, only one single histologically and molecularly confirmed case was documented in the literature up to this time. We report a case of a 38-yearold woman with obstructive hydrocephalus secondary to a brain tumor within the third ven...

Pneumocephalus or air within the cranial vault is usually associated with a series of symptoms caused by head trauma, the presence of neoplasms or after craniofacial surgical interventions or other causes. We report a case report of an elderly patient who presented with postural instability with an anamnestic history that didn’t talk about traumatic events. We review briefly the literature for nontraumatic causes causes of pneumocephalus, its symptoms and clinical manifestations and finally th...

Prolyl oligopeptidase (POP) is a cytosolic serine protease with prominent expression in the brain. Inhibition of this enzyme leads to cognition-enhancing and neuroprotective effects in animal models with cognitive deficits. However, the biological function of POP remains unknown. Although in the past it was though that its catalytic activity was responsible for its physiological role, lately it has been hypothesized that POP is involved in the inositol pathway and that it interacts with several ...

complex relationship exists between mood and pain, which is supported by different pain tolerance in clinically depressed patients compared to healthy people. In the present study we aimed to investigate pressure pain threshold (PPT) in unipolar and bipolar depressed patients and assess any differences between these two diagnoses. This study included 40 patients diagnosed with unipolar depression and 89 patients diagnosed with bipolar depression according to DSM-IV criteria, also 40 healthy, age...

Brain radiation necrosis (BRN) is a side effect of radiotherapy (RT), affecting mainly the white matter and can appear from a few weeks to several years after RT. It's incidence of 3-9% is increasing as survival increases. Histopathology (HP) shows avascular damage, demyelination and direct necrosis. Brain radiation radionecrosis and the tumor progression are difficult to differentiate as both entities are presented with similar radiological and clinical characteristics, such as neurological def...
