Dyskeratosis congenita (DKC) is a rare, inherited disorder classically known by the triad of nail dystrophy, mucosal leukoplakia, and lacy reticulated skin hyperpigmentation. Bone marrow failure is a prominent feature and accounts for most deaths in these patients. Genetic mutations resulting in shortened telomeres have been shown to cause DKC, which is the basis for categorizing it as a "premature aging syndrome". Different modes of inheritance have been identified with X-linked recessive as the most common...

The novel neurite outgrowth inhibitor B (Nogo‑B) receptor (NgBR) is specific for Nogo‑B, which is highly expressed in various human organs and cells, including the lung, liver, kidney, smooth muscle cells, blood vessel endothelial cells and inflammatory cells. Previous studies have indicated that NgBR directly interacts with Nogo‑B and is able to independently influence lipid and cholesterol homeostasis, angiogenesis, N‑glycosylation, the epithelial-mesenchymal transition, the chemotaxis of endothelial cells and cellular proliferation and apoptosis...

Primary brain tumors are a leading cause of cancer-related morbidity and mortality in children. Glioblastoma (GBM) is a high-grade astrocytoma that occurs in both children and adults and is associated with a poor prognosis. Despite extensive study in recent years, the clinical management of these tumors has remained largely unchanged, consisting of surgical resection, conventional chemotherapy, and radiotherapy. Although the etiology and genomic drivers in GBM are diverse, constitutional mismatch repair-deficiency (CMMRD) syndrome is a rare, recessively inherited disease with a predisposition to gliomagenesis...

BACKGROUND: Inflammatory response plays a vital role in the pathological mechanism of intracerebral hemorrhage. It has been recently reported that neutrophil to lymphocyte ratio (NLR) could represent a novel composite inflammatory marker for predicting the prognosis of intracranial hemorrhage (ICH). However, in considering that surgical evacuation effects on the initiation of inflammatory responses. Thus, the relationship between NLR and functional outcome of ICH patients after surgical treatment is still controversial...

BACKGROUND: Interleukin-33 (IL-33) is an inflammatory biomarker. We elucidated the relationship between serum IL-33 concentrations, severity and prognosis in aneurysmal subarachnoid hemorrhage (aSAH). METHODS: We prospectively recruited 175 controls and 175 aSAH patients. Serum IL-33 concentrations were gauged using an enzyme-linked immunosorbent assay. Clinical and radiological severity was assessed by World Federation of Neurological Surgeons (WFNS) scale and modified Fisher grading scale respectively...

To guide management of patients with acute spinal cord injuries, we developed intraspinal pressure monitoring from the injury site. Here, we examine the complex fluctuations in the intraspinal pressure signal using network theory. We analyzed 7,097 hours of intraspinal pressure data from 58 patients with severe cord injuries. Intraspinal pressure signals were split into hourly windows. Each window was mapped into a visibility graph as follows: Vertical bars were drawn at 0.1 Hz representing signal amplitudes...

Giant brain aneurysms account for approximately 5% of all intracranial aneurysms. Although treatment modalities can vary widely, none is ideal for every patient. Endovascular treatment is usually preferred, especially when the large size of the aneurysm limits visualization of the brain parenchyma and parent vessels that arise from the aneurysm, making surgical clip placement across the neck a difficult task. However, despite the higher chances of morbidity, microsurgery is an effective treatment modality due to lower recurrence rates...

Introduction: Obstructive sleep apnea (OSA) patients show hippocampal-related autonomic and neurological symptoms, including impaired memory and depression, which differ by sex, and are mediated in distinct hippocampal subfields. Determining sites and extent of hippocampal sub-regional injury in OSA could reveal localized structural damage linked with OSA symptoms. Methods: High-resolution T1-weighted images were collected from 66 newly-diagnosed, untreated OSA (mean age ± SD: 46...

Posterior inferior cerebellar artery (PICA) aneurysms account for 3% to 4% of all intracranial aneurysms with an unusually high predilection towards a nonsaccular morphology making microsurgical clipping or endovascular reconstruction of the parent artery difficult. The management of these complicated aneurysms may require revascularization procedures for flow preservation with aneurysm trapping. Recently, there is an increasing inclination towards intracranial-intracranial (IC-IC) bypasses over traditional extracranial donors...

Children with arteriovenous malformations (AVMs) are at cumulative, life-long risk of debilitating and fatal intracranial hemorrhage, especially with syndromes such as hereditary hemorrhagic telangiectasia. Cerebral angiography is the gold standard for diagnosis and allows simultaneous adjunctive embolization limiting radiation and contrast exposure and intraoperative blood loss, important in pediatric patients with low blood volume. Microsurgical resection of low-grade AVMs offers cure with minimal morbidity...

While revascularization of the acutely or chronically occluded internal carotid artery has become commonplace with modern endovascular techniques, revascularization of an acutely occluded common carotid artery (CCA) is a controversial procedure with unique challenges. These challenges can be related to the lack of observable markers for identifying vessels during navigation or for identifying the exact location and extent of occlusion within the CCA, in addition to wide-ranging treatment risks. In this video, we illustrate the controversial revascularization of a 68-yr-old woman with an acute CCA occlusion who presented with fluctuating neurological symptoms...
