Meningitis is a potentially fatal inflammation of the meninges, the thin, membranous covering of the brain and the spinal cord. Meningitis is most commonly caused by infection (by bacteria, viruses, or fungi), although it can also be caused by bleeding into the meninges, cancer, diseases of the immune system, and an inflammatory response to certain types of chemotherapy or other chemical agents.
Pneumococcal vaccine offers protection to HIV-infected African adults in clinical trial – A clinical trial of a vaccine against a major cause of pneumonia and meningitis has shown that it can prevent three out of four cases of re-infection in HIV-infected adults in Africa.
Lyme disease is spreading in Canada, and physicians are crucial in helping minimize its impact – Lyme disease is emerging in Canada, and is expected to increase with climate change, but effective, enhanced surveillance and clinician awareness will be key to minimizing the impact of the disease, write researchers in a review in CMAJ (Canadian Medical Association Journal).
AIDS patients with serious complications benefit from early retroviral use, Stanford study shows – HIV-positive patients who don’t seek medical attention until they have a serious AIDS-related condition can reduce their risk of death or other complications by half if they get antiretroviral treatment early on, according to a new multicenter trial led by researchers at the Stanford University School of Medicine.
Meningitis bacteria dress up as human cells to evade our immune system – The way in which bacteria that cause bacterial meningitis mimic human cells to evade the body’s innate immune system has been revealed by researchers at the University of Oxford and Imperial College London.
Results published in New England Journal of Medicine resolve questions about pediatric vaccine’s efficacy in preventing spread of the pneumococcal meningitis disease to adults. – A standard pediatric vaccine used to prevent several common types of life-threatening infections also effectively reduced the rates of another disease, pneumococcal meningitis, in children and adults, according to a multi-center study led by the University of Pittsburgh School of Medicine.
US FDA Approves Updated Labeling for Psoriasis Drug Raptiva by Genentech; Safety concerns drove labeling changes. – The U.S. Food and Drug Administration announced labeling changes, including a Boxed Warning, to highlight the risks of life-threatening infections, including progressive multifocal leukoencephalopathy (PML), with the use of Raptiva (efalizumab).
A study published in PLoS Medicine this week suggests that of women who die during pregnancy and childbirth in sub-Saharan Africa, more may die from treatable infectious diseases than from conditions directly linked to pregnancy. – Women who die during pregnancy and childbirth in sub-Saharan Africa, more may die from treatable infectious diseases than from conditions directly linked to pregnancy, revealed by researchers.
DNA sequencing establishes high throughput genetic sequencing as powerful tool for pathogen discovery; technology enables improvements in screening for transplant safety. – In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, link the discovery of a new arenavirus to the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia in April 2007.
Professor John Kappelman of The University of Texas at Austin reveals the most ancient evidence of the tuberculosis disease has been found in a 500,000-year-old human fossil from Turkey.
– Although most scientists believe tuberculosis emerged only several thousand years ago, new research from The University of Texas at Austin reveals the most ancient evidence of the disease has been found in a 500,000-year-old human fossil from Turkey.
