Re-induction chemotherapy regimens in patients with recurrent central nervous system mixed malignant germ cell tumors.

The lack of a standard treatment approach has contributed to poor outcomes of patients with recurrent central nervous system (CNS) mixed malignant germ cell tumors (MMGCT). There are no data in the literature supporting optimal re-induction chemotherapy regimens that should be used for patients with recurrent CNS MMGCT.


Radiotherapy for anal squamous cell carcinoma: must the upper pelvic nodes and the inguinal nodes be treated?

Loco-regional failure is the predominant cause of death in anal squamous cell carcinoma. We assessed patterns of loco-regional recurrence to determine the impact of radiotherapy (RT) volumes on patient outcome.

Role of endothelial-to-mesenchymal transition in the pathogenesis of central nervous system hemangioblastomas.

Hemangioblastomas (HBs) are benign vascular tumors of the central nervous system and histologically contain abundant microvessels. Therefore, they clinically exhibit vascular malformation-like characteristics. It has been described that endothelial-to-mesenchymal transition (EndMT) contributes to the pathogenesis of cerebral cavernous malformations. However, it remains unknown whether EndMT contributes to the pathogenesis of central nervous system HBs. The aim of our study was to investigate whether EndMT o...


Characterization of genomic alterations in primary central nervous system lymphomas.

Primary central nervous system lymphoma (PCNSL) is a non-Hodgkin lymphoma that affects the central nervous system (CNS). Although previous studies have reported the most common mutated genes in PCNSL, including MYD88 and CD79b, our understanding of genetic characterizations in primary CNS lymphomas is limited. The aim of this study was to perform a retrospective analysis investigating the most frequent mutation types, and their frequency, in PCNSL.

Primary central nervous system histiocytic sarcoma: A case report and review of literature.

Primary central nervous system histiocytic sarcoma (PCNSHS) is a rare lymphohematopoietic tumor with a histiocytic cell origin. To our knowledge, only 28 cases have been published in English and 2 cases in Chinese.

Intracranial immature teratoma invading the nasal cavity mimicking olfactory neuroblastoma: A case report.

Primary intracranial immature teratoma accounts for majority of congenital central nervous system germ-cell tumors, but it is extremely rare in patients older than 15 years.

Risk of central nervous system defects in offspring of women with and without mental illness.

We sought to determine the relationship between maternal mental illness and the risk of having an infant with a central nervous system defect. We analyzed a cohort of 654,882 women aged less than 20 years between 1989 and 2013 who later delivered a live born infant in any hospital in Quebec, Canada. The primary exposure was mental illness during pregnancy or hospitalization for mental illness before pregnancy. The outcomes were neural and non-neural tube defects of the central nervous system in any offspri...

Quantification of the Central Cardiovascular Network Applying the Normalized Short-time Partial Directed Coherence Approach in Healthy Subjects.

The central control of the autonomic nervous system (ANS) and the complex interplay of its components can be described by a functional integrated mode - the central autonomic network (CAN). CAN represents the integrated functioning and interaction between the central nervous system (CNS) and ANS (parasympathetic and sympathetic activity).

Molecular Architecture of the Mouse Nervous System.

The mammalian nervous system executes complex behaviors controlled by specialized, precisely positioned, and interacting cell types. Here, we used RNA sequencing of half a million single cells to create a detailed census of cell types in the mouse nervous system. We mapped cell types spatially and derived a hierarchical, data-driven taxonomy. Neurons were the most diverse and were grouped by developmental anatomical units and by the expression of neurotransmitters and neuropeptides. Neuronal diversity was d...

Central Nervous System Germinomas Express Programmed Death Ligand 1.

Immunomodulation and tumor-induced tolerance is one of the central mechanisms in the oncogenesis of malignant and benign neoplasms. While numerous pathways have been described, signaling through the programmed death receptor 1 (PD-1) on T lymphocytes, via activation through its ligand, programmed death ligand 1 (PD-L1) expressed on tumor cells is one of the central pathways involved in tumor-induced tolerance. While the neoplastic component of germinomas of the CNS is the germ cell, these tumors also exhibi...

Fatal central nervous system lymphocytic vasculitis after treatment for Burkitt lymphoma in a patient with a SH2D1A mutation.

Very rarely, patients with X-linked lymphoproliferative syndrome type 1 present central nervous system vasculitis. We report a patient carrying a SH2D1A mutation that, after treatment for lymphoma developed fatal CNS vasculitis. He lacked signs of ongoing EBV infection. We propose that impaired T cell homeostasis caused by SAP-deficiency facilitates aberrant CD8 T cell activation against vascular antigens promoting clinical manifestations.

Craniotomy and Survival for Primary Central Nervous System Lymphoma.

Cytoreductive surgery is considered controversial for primary central nervous system lymphoma (PCNSL).

Central Nervous System Myelomatosis Delineated by High-Resolution Brain Images From Fully Digital 18F-FDG PET.

Central nervous system myelomatosis is uncommon and is associated with a particularly poor prognosis. PET images, from a 53-year-old man referred to a fully digital F-FDG PET for relapsed multiple myeloma, revealed high F-FDG uptakes located in the cortex and sulci of the right central area and within the meningeal envelopes of the cerebellum, the trigeminal nerves, and on the spinal canal. These particular uptakes gave evidence of a central nervous system myelomatosis subsequently confirmed by plasma cells...

HIV neuropathology.

Primary human immunodeficiency virus (HIV) neuropathologies can affect all levels of the neuraxis and occur in all stages of natural history disease. Some, like HIV encephalitis, HIV myelitis, and diffuse infiltrative lymphocytosis of peripheral nerve, reflect productive infection of the nervous system; others, like vacuolar myelopathy, distal symmetric polyneuropathy, and central and peripheral nervous system demyelination, are not clearly related to regional viral replication, and reflect more complex cas...

Viruses have multiple paths to central nervous system pathology.

Although viral infections of the central nervous system (CNS) are known to acutely cause pathology in the form of cytokine-mediated neural tissue damage and inflammation, the pathophysiology of neurologic sequelae after viral clearance is incompletely understood.

Neuroinflammation and Central Sensitization in Chronic and Widespread Pain.

Chronic pain is maintained in part by central sensitization, a phenomenon of synaptic plasticity, and increased neuronal responsiveness in central pain pathways after painful insults. Accumulating evidence suggests that central sensitization is also driven by neuroinflammation in the peripheral and central nervous system. A characteristic feature of neuroinflammation is the activation of glial cells, such as microglia and astrocytes, in the spinal cord and brain, leading to the release of proinflammatory cy...

Diffusion and perfusion MR patterns of central nervous system lymphomas.

Central nervous system lymphomas (CNSLs) are rare tumors which may show variable appearance in standard magnetic resonance imaging (MRI) depending on their origin (primary or secondary) or patients' immunological status.

Outcomes of Pediatric Central Nervous System Tuberculosis in California, 1993-2011.

Our goal was to describe the characteristics and posttreatment outcomes of pediatric patients with central nervous system (CNS) tuberculosis (TB) and to identify factors associated with poor outcome.

Axon Regeneration in the Central Nervous System: Facing the Challenges from the Inside.

After an injury in the adult mammalian CNS (central nervous system), lesioned axons fail to regenerate. This failure to regenerate contrasts with axons' remarkable potential to grow during embryonic development and after an injury in the PNS (peripheral nervous system). Several intracellular mechanisms-including cytoskeletal dynamics, axonal transport and trafficking, signaling and transcription of regenerative programs, and epigenetic modifications-control axon regeneration. In this review, we describe how...

A brain within the heart: A review on the intracardiac nervous system.

Cardiac function is under the control of the autonomic nervous system, composed by the parasympathetic and sympathetic divisions, which are finely tuned at different hierarchical levels. While a complex regulation occurs in the central nervous system involving the insular cortex, the amygdala and the hypothalamus, a local cardiac regulation also takes place within the heart, driven by an intracardiac nervous system. This complex system consists of a network of ganglionic plexuses and interconnecting ganglio...

Termination of pregnancy following prenatally diagnosed central nervous system malformations.

To analyze fetal cerebral malformations with late termination of pregnancy (TOP) and to evaluate the rate of cases that could have been detected earlier using international recommended requirements of sonographic examination of the fetal central nervous system (CNS).

Immune cell profiling in the cerebrospinal fluid of patients with primary angiitis of the central nervous system reflects the heterogeneity of the disease.

Primary angiitis of the central nervous system (PACNS) is a rare and heterogeneous inflammatory disease of the CNS vasculature with poorly understood pathophysiology. Comprehensive immune-cell phenotyping revealed increased frequencies of leukocytes in the cerebrospinal fluid (CSF) of PACNS patients compared to patients with multiple sclerosis, ischemic stroke, and somatoform disorders (n = 18 per group). Changes in the intrathecal immune-cell profile were heterogeneous in PACNS. While proportions of T-...

Premature Mortality Due to Malignancies of the Central Nervous System in Canada, 1980-2010.

In this study, we investigated whether there has been an improvement in premature mortality due to central nervous system (CNS) cancers among the Canadian population from 1980 through 2010.

Glia-neuron energy metabolism in health and diseases: New insights into the role of nervous system metabolic transporters.

The brain is, by weight, only 2% the volume of the body and yet it consumes about 20% of the total glucose, suggesting that the energy requirements of the brain are high and that glucose is the primary energy source for the nervous system. Due to this dependence on glucose, brain physiology critically depends on the tight regulation of glucose transport and its metabolism. Glucose transporters ensure efficient glucose uptake by neural cells and contribute to the physiology and pathology of the nervous syste...

Impact of remnant vital tissue after locoregional treatment and liver transplant in hepatocellular cancer patients, a multi centre cohort study.

The role of pathological findings after loco-regional treatments as predictors of hepatocellular cancer recurrence after liver transplantation has been poorly addressed. The aim of the study was to identify the role of remnant vital tissue (RVT) of the target lesion in predicting hepatocellular cancer recurrence. Two hundred seventy six patients firstly undergoing loco regional treatment and then transplanted between Jan2010-Dec2015 in four European Transplant Centres (i.e., Rome Tor Vergata, Birmingham, Br...
