Acute hemorrhagic leukoencephalitis
MONDO:0011716Acute hemorrhagic leukoencephalitis(AHL) is a veryrareform of acute disseminated encephalomyelitis that usuallyresults indeath. It is characterized by a brief but intense attack of inflammation in the brain and spinal cord that damages the myelin -- the protective covering of the nerve fibers. It may also cause bleeding in the brain, leading to damage of the white matter. Symptoms usually come on quickly, beginning with symptoms such as fever, neck stiffness, fatigue, headache, nausea vomiting,seizures, and coma.AHL has a very poor prognosis, with rapid deterioration and death usually occurring within days to one week after onset of symptoms because of severe inflammation in the brain. Although the exact cause is unclear,AHL usually followsaviral infection, or less often, vaccination for measles, mumps, or rubella. Some researchers think that an infection or vaccination can initiate an autoimmune process in the body thus leading to AHL.

Which antibiotic combo is safer for your kidneys? new trial aims to find out
Disease control Not yet recruitingThis study compares two common antibiotic combinations—vancomycin with piperacillin/tazobactam versus vancomycin with meropenem—to see which is less harmful to the kidneys. About 852 hospitalized adults with serious infections will be randomly assigned to one of the two combos. T…

Can the Body's own 'Off Switch' for inflammation predict who survives severe infection?
Knowledge-focused Not yet recruitingThis study will follow 300 adults with severe infections in the ICU to see how levels of specialized pro-resolving mediators (SPMs)—natural molecules that help stop inflammation—change over time. Researchers will use blood samples already collected during routine care, so no extr…
