Central nervous system tumors are relatively common in the United States, with more than 40,000 cases annually. Although more than half of these tumors are benign, they can cause substantial morbidity. Malignant primary brain tumors are the leading cause of death from solid tumors in children and the third leading cause of death from cancer in adolescents and adults aged 15 to 34 years. Common ...

Lipoprotein and cholesterol metabolism in the brain involves metabolic pathways that are regulated independently of those in the peripheral circulation and tissues. The blood–brain barrier (BBB) restricts plasma lipids, including cholesterol and plasma lipoproteins, from entering or leaving the central nervous system (CNS). In the CNS, cholesterol is synthesized by astrocytes, oligodendrocytes,...

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 ...

, SlR,—We read with interest the article by Dr Nesbit and others (June 27, p. 1386) on isolated central nervous system acute lymphocytic leukaemia in children. In this very helpful article Nesbit et aL state that "CNS relapse rates are lower in patients receiving effective treatment before CNS symptoms arise, but the bone marrow relapse rate was not significantly affected by prophylactic ...

Degenerative diseases of the nervous system in children are acknowledged to be chronic (usually) and destructive (invariably), and for the biochemically oriented clinician they provide a challenging interest because most are genetically, and probably, therefore, chemically determined. Individually relatively rare, most of them are inherited as autosomal recessive conditions, and by implication ...

Tuberculosis (TB) has shown a resurgence in nonendemic populations in recent years and accounts for 8 million deaths annually in the world. Central nervous system involvement is one of the most serious forms of this infection, acting as a prominent cause of morbidity and mortality in developing countries. The rising number of cases in developed countries is mostly attributed to factors such as ...

Systemic Lupus Erythematosus (SLE) is a complex clinical syndrome which its components are less clearly recognized and includes heterogeneous demonstrations engaging both central and peripheral nervous system along with disabling effects. This disease is called "thousand faces" due to these heterogeneous demonstrations. This gap exists while 75% of adults and children with SLE may dea...

Involvement of the central nervous system (CNS) by Mycobacterium tuberculosis, particularly meningitis, is the most severe form of tuberculous infection. Parenchymal CNS involvement can occur in the form of tuberculoma or, more rarely, abscess. Although surgery was initially advocated as the mainstay of therapy, more recent evidence suggests that parenchymal forms of CNS tuberculosis can be cur...
