Eradicating Polio – The Final Inch

Wednesday, November 19th, 2008

Poliomyelitis is a deadly disease which may affect the central nervous system leading to irreversible flaccid paralysis of the legs. Since it strikes children at a very young age, affected children are paralyzed for their entire life.

Google’s philanthropic arm – Google.org is about to release a movie titled “The Final Inch” to document the historic effort to eradicate this disease from the planet. Once we succeed this will be second disease after small pox to be found only in history books (and/or some covert lab, somewhere in the world).

The Final Inch is a 38-minute film about the historic global effort to eradicate polio. Here, the story told is as much about the messengers as the message. You’ll meet Munzareen Fatima, one of the thousands of community “foot soldiers” across India working to sway reluctant families to vaccinate their children, and Dr. Ashfaq Bhat, who travels into the backwaters of India’s Ganges Basin by boat and foot to detect emerging cases of polio. Martha Mason and Mikail Davenport bring us into their lives and describe the paralyzing challenges of childhood polio, reminding us how endemic polio once was in the United States.

Filmed in high-definition (HD) in cinematic style — wide open shots to give a strong sense of place — The Final Inch captures their stories, and we hope it is both a tribute and an inspiration of hope. With a final push, this is a disease that can, and should, be eradicated finally.

The movie airs on HBO in 2009. Check out the film trailer:

AIDS: Mortality in numbers and pictures

Sunday, October 26th, 2008

Acquired Immuno-deficiency Syndrome (AIDS) is potentially fatal disease caused by HIV virus. AIDS renders our body defenseless against any and every infection in the world by killing the immune system.

The currently available treatment – highly active anti-retroviral treatment (HAART) is very effective in giving people a few more decades to live. However, HAART has 2 major problems:

  1. It is not a cure and the medications have to be taken lifelong
  2. The side effects of treatment at times may be as bad as cancer chemotherapy

Therefore, it is of imperative importance that we find a cure for this deadly disease which is safer (ideally without side effects) and does not need to be taken over a protracted period of time.

Anemia – NY Times Health

Saturday, July 19th, 2008

New York Times has an excellent in depth review of anemia which everyone should read.

Thanks to advertisements for the once-popular tonic Geritol, most people of a certain age know about “tired blood,” a disorder more accurately called anemia, involving a shortage of healthy red blood cells to carry oxygen to body tissues and cleanse them of carbon dioxide.

The red blood cells of a person suffering from anemia (right) are a very light pink when stained, and they are often less round and full when viewed under a microscope. The round, plump bodies of normal red blood cells (left), when stained, are a bright pinkish-red. Hemoglobin is the substance that gives normal cells their bright color.
