MEDICAL ANIMATION TRANSCRIPT: Influenza, or the flu, is a contagious viral infection that attacks your nose, throat, and lungs. It can cause fever, chills, runny nose, sore throat, cough, muscle aches, and fatigue. The flu virus is extremely small and only visible through electron microscopes. Inside the virus, genetic material contains the information to make more copies of the same virus. A protein shell provides a hard, protective enclosure for the genetic material as the virus travels between the people or animals it infects. An outer envelope allows the virus to infect cells by merging with the cell's outer membrane. Projecting from the envelope are spikes of protein molecules. The flu virus uses its H spikes like a key to get inside your cells. N spikes allow copies of the virus to break away from your infected cells to infect more cells. There are 17 known types of H spikes and nine types of N spikes that scientists use to name different flu viruses, such as the virus H5N1. You get the flu by touching an object that has the flu virus on it or through exposure to body fluids from people or animals infected with the virus. When an infected person talks, coughs, or sneezes, droplets carrying the influenza virus may land in your mouth or nose and then move into your lungs. Once inside your body, the influenza virus comes into contact with cells in your nose, throat, or lungs. The H spike on the virus inserts into a receptor molecule on your healthy cell membrane, like a key in a lock. This action allows the virus to get inside your cell. Next, the virus travels inside a sack made from your cell membrane to your cell's nucleus. Then the viral envelope and cell membrane sack combine, allowing the viral genetic material to leave the sack and enter the nucleus. The viral genetic material hijacks the energy and materials in your cell's nucleus to make thousands of copies of itself. Some of the genetic material moves out of the nucleus, then attaches to ribosomes, which are the protein building parts of your cell. Ribosomes use information from the genetic material to make other viral proteins, such as the H and N spikes. A packaging structure in your cell, called the Golgi apparatus, carries the H and N spikes in vesicles which merge with your cell's membrane. All the parts needed to create a new virus gather just beneath your cell's membrane. Then a new virus begins to bud off from the cell's membrane. During this process, the newly created virus gets stuck on your cell's membrane when a viral H spike locks onto membrane receptors. However, the virus has a way to get around this problem. The viral N spike frees the virus by cutting it away from the receptor. New influenza viruses are now free to infect more of your cells and cause you to develop the flu. If you have the flu, your doctor may prescribe Oseltamivir, which you would take orally, or Zanamivir, which you would take using an inhaler, to help speed your recovery or reduce your risk for complications. These anti-viral drugs stop the influenza virus by blocking the viral N spike from freeing the virus. This causes the new viruses to stick to the surface of your cell, so they cannot escape and infect more of your cells. The best way to protect yourself from the flu is to get the flu vaccine every year. You may receive the vaccine as a shot, which contains dead versions of several types of the virus, or you may receive it as a nasal spray, which contains several types of live, but very weak, forms of the virus. The vaccine exposes your body to several types of the influenza virus that are too weak to cause infection but just strong enough to stimulate an immune response. Within two weeks, cells in your immune system make markers called antibodies, which are specific for only the types of flu you were exposed to. The antibodies attach to each flu virus and prevent it from attaching to your cells. Antibodies are also able to attach to more than one flu virus, which causes viruses to clump together. Your immune system responds to signals from the antibodies by engulfing and destroying the clumps of viruses. Later, if you are exposed to these types of flu again, your body recognizes and destroys them, so you will not develop the flu from these same viruses. For continued protection against new flu viruses, you will need to get a flu vaccine every year.
"I wanted to thank you for the terrific job you did illustrating my client's
injuries. The case was settled at the pre-suit mediation, and I believe a
good part of the success we had was due to the medical legal art you
prepared.
Your work received the ultimate compliment at the conclusion of the mediation. The hospital risk manager took the exhibit with them at the
conclusion of mediation, and will be using it to train nurses on how to
prevent bed sores..."

"I just wanted to let you know that after several days on trial, I settled
[my client's] construction accident case for $4.5 million. Immediately after
the jury was discharged, I spoke with several jurors who told me that they
really appreciated the medical illustrations for their clarity in dealing
with [my client's] devastating injuries. They also expressed their gratitude
in being able to read from a distance all of the notations without
difficulty. Obviously, the boards were visually persuasive. I am certain
that this contributed to our successful result."

"At 3 PM it hit me--I needed exhibits of a tracheostomy, a coronary artery
bypass and a deep vein thrombosis--all in time for a for-trial video
deposition the next day. The Doe Report had each exhibit on line. In
addition, I ran across an exhibit I hadn't even thought of: reduced ejection
fraction after a heart attack. Because this was a video deposition, I could
use the e-mail version of the medical exhibit, print it on my color copier,
and let the camera zoom in. For $400, less than one blow-up by one of The
Doe Report's competitors, I got four first-rate exhibits in less than a day.
The Doe Report saved me time and money."
"It is with great enthusiasm that I recommend Medical Legal Art. We have
used their services for three years and always found their professionalism,
quality of work, and timely attention to detail to exceed our expectations.
We recently settled two complicated catastrophic injury cases. One medical
malpractice case involving a spinal abscess settled for 3.75 million and the
other involving injuries related to a motor vehicle accident settled for 6.9
million. We consider the artwork provided by MLA to have been invaluable in
helping us to successfully conclude these cases.
I highly recommend MLA to anyone seeking high quality, detailed medical
legal artwork."
