The CNS (central nervous system) is unquestionably the central organ that regulates directly or indirectly all physiological systems in the mammalian body. Yet, when considering the defence of the CNS from pathogens, the CNS has often been considered passive and subservient to the pro-inflammatory responses of the immune system. In this view, neuroinflammatory disorders are examples of when the...

Background: Tumors of the central nervous system (CNS) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of CNS. Objectives: Determining the relative frequency of different types of CNS tumors in different ages, sex and CNS anatomical locations. Materials and Methods: This retrospective study was performed using pathological repor...

Background: Central Nervous System (CNS) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, Intrathecal chemotherapy and cranial irradiation. The purpose of this study was to compare the effectiveness of intrathecal (IT) CNS chemotherapy alone versus combination of IT chemotherapy with cranial irradiation for prevention of CNS rel...

Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...

Alzheimer’s disease (AD) is a neurodegenerative disease that is the most common type of dementia.AD includes 60_80% of dementia and most people with AD have more than 65 years old.AD causes losing neuronal activity by abnormal proteins. Plaques of beta-amyloid and tangles of “tau” protein can lead to AD. Recently evidence has found that AD may come from outside of central nerv...

Tuberculosis is a formidable disease worldwide because of its highly infectious nature and propensity for latency. The increasing prevalence of tuberculosis in both immunocompetent and immunocompromised individuals in recent years makes this disease a topic of universal concern. The disease has insidious onset and can affect virtually any organ system in the body, including the central nervous ...

Viruses invade susceptible cells through a complex mechanism before injecting their genetic material into them. This causes direct damage to the host cell, as well resulting in disease corresponding system. Echovirus type 30 (E30) is member of Enterovirus B group and has recently been reported cause central nervous system (CNS) disorders, leading viral encephalitis meningitis children. In this ...

CNS: central nervous system CSF: cerebrospinal fluid PCMZL: primary cutaneous marginal zone lymphoma WBC: white blood cells BACKGROUND Primary cutaneous marginal zone lymphoma (PCMZL) is an indolent B-cell lymphoma, typically characterized by frequent cutaneous recurrences and rare systemic involvement. Lymph nodes, bone, and bone marrow are commonly affected sites in rare cases of extracutaneo...

Primary dural lymphoma (PDL) is a subtype of primary central nervous system (CNS) (PCNSL) with only an extra-axial location. It accounts for less than 1% all CNS lymphomas. PDL sporadic tumor, and in the preoperative period, because imaging characteristics, it usually mimicking meningioma. Usually, low-grade B-cell relatively good response to surgical resection or without radiotherapy. Here we ...

We reported two cases of the central nervous system (CNS) multiple myeloma (MM) with unusual presentation sixth nerve palsy. The first patient developed in setting newly diagnosed MM and second relapsed refractory setting. One underwent surgery, other received radiation. Both patients systemic chemotherapy noted improvement. also performed a comprehensive literature review previously published ...
