Viral Meningitis - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: Viral meningitis is an infection occurring mostly in children under age five. It happens when certain viruses invade the meninges, which are the tissues that cover and protect the brain and spinal cord. The meninges are arranged in three layers. The layer that actually touches the brain and spinal cord is called the pia mater. The spider web-like middle layer is called the arachnoid mater. The outermost and toughest layer is called the dura mater. Cerebrospinal fluid, which also protects the brain and spinal cord, flows between the meninges and over the surface of the brain. The most common cause of viral meningitis is a type of virus called enterovirus. Other viruses that can cause meningitis include the mumps virus, the measles virus, herpes viruses, and a variety of viruses spread by blood-feeding insects, such as mosquitoes and ticks. Viruses that cause meningitis may be spread through the bite of an infected insect. However, the two most common ways the virus is spread are through fecal contamination, which can happen when hands are not washed after using the toilet or changing a diaper, and through contact with the body fluids from an infected person, such as through sneezing or coughing. Once inside the body, the viruses make copies of themselves and enter the bloodstream. Viruses travel through the bloodstream to the brain, where they cross the border between the blood stream and the brain into the cerebrospinal fluid. The viruses spread throughout the cerebrospinal fluid and infect the cells of the meninges. The meninges become inflamed as the immune system begins to fight off the infection. Symptoms of viral meningitis in infants and young children include fever, irritability, loss of appetite, and trouble waking up. Symptoms in older children and adults include fever, headache, stiff neck, sensitivity to light, sleepiness, trouble waking up, nausea, vomiting, and loss of appetite. The symptoms of viral meningitis are similar to those of bacterial meningitis but are usually less severe. Doctors may recommend acetaminophen or other non-steroidal anti-inflammatory drugs for fever and headache. For meningitis caused by a type of herpes virus, doctors may prescribe an anti-viral medication, such as acyclovir. There is no treatment for most viruses that cause meningitis, though most people recover on their own within two weeks.

What attorneys say about MLA and The Doe Report:
"I would like to thank all of you at Medical Legal Art for all the assistance you provided. It was a result of the excellent, timely work that we were able to conclude the case successfully.

I feel very confident that our paths will cross again."

"I wanted to take some time out to let you know what a wonderful job you did with the 'collapsed lung/fractured rib' illustrations. They were both detailed and accurate. My medical expert was comfortable working with them and he spent at least an hour explaining to the jury the anatomy of the lungs, the ribs and the injuries depicted in the illustrations. Needless to say, the jury was riveted to the doctor during his testimony.

The jury returned a verdict for $800,000.00 and I'm sure we would not have done so well if not for the visualizations we were able to put forth with your assistance. Lastly, my special thanks to Alice [Senior Medical Illustrator] who stayed late on Friday night and patiently dealt with my last minute revisions."

"Your firm is great to work with and, most importantly for me, you get the job done on time and with the utmost professionalism. You should be proud of all those you employ, from KJ to Ben B. I've been especially pleased over the years with the work of Brian and Alice, both of whom seem to tolerate my idiosycratic compulsion to edit, but I've not found a bad apple in the bunch (and, as you know, I've used your firm a bunch!). I look forward to our continued professional relationship."

"We got a defense verdict yesterday! Your exhibit was extremely helpful in showing the jury how unlikely it is to damage all four of the nerve branches which control the sense of taste."
