Growth indicated a bacterial meningitis, while no growth indicated another cause denoted "aseptic" meningitis. [1] The most common form of this is viral meningitis. [1] Recent medical advances allows rapid polymerase chain reaction (PCR) testing that analyzes the CSF for DNA or RNA. This can quickly determine if there are bacterial or viral ...
The term aseptic meningitis refers to cases of meningitis in which no bacterial infection can be demonstrated. This type of meningitis is usually caused by viruses, but it may be due to bacterial infection that has already been partially treated, when bacteria disappear from the meninges, or when pathogens infect a space adjacent to the ...
Viral meningitis, also known as aseptic meningitis, is a type of meningitis due to a viral infection. It results in inflammation of the meninges (the membranes covering the brain and spinal cord). Symptoms commonly include headache, fever, sensitivity to light and neck stiffness. [1] Viruses are the most common cause of aseptic meningitis.
Some of the possible symptoms of chronic meningitis (due to any cause) include headache, nausea and vomiting, fever, and visual impairment. Nuchal rigidity (or neck stiffness with discomfort in trying to move the neck), a classic symptom in acute meningitis, was seen in only 45% of cases of chronic meningitis with the sign being even more rare in non-infectious causes.
Meningococcal disease describes infections caused by the bacterium Neisseria meningitidis (also termed meningococcus). [1] It has a high mortality rate if untreated but is vaccine-preventable. [2] While best known as a cause of meningitis, it can also result in sepsis, which is an even more damaging
Additionally, the probability of developing aseptic meningitis increases when patients have a case of mumps or herpes. [2] Symptoms of meningitis caused by an acute viral infection last between one and two weeks. When aseptic meningitis is caused by cytomegalovirus 20 percent of individuals face mortality or morbidity. If left untreated it can ...
[6] [7] Suspicion of meningitis is a medical emergency and immediate medical assessment is recommended. Current guidance in the United Kingdom is that if a case of meningococcal meningitis or septicaemia (infection of the blood) is suspected, intravenous antibiotics should be given and the ill person admitted to the hospital.

Design features of an operating microscope are: magnification typically in the range from 4x-40x, components that are easy to sterilize or disinfect in order to ensure cross-infection control. There is often a prism that allows splitting of the light beam in order that assistants may also visualize the procedure or to allow photography or video ...
