Results: Strange But True Part 5

Imagine being pregnant and suddenly noticing every surface you touch turning blue -- your sheets, your clothes and even the toilet seat. It turns out that Keisha Sethi was diagnosed with chromhidrosis, a very rare condition, not with an unusual pregnancy symptom. The main symptom of chromhidrosis, according to Medical News Today, is colored sweat; it could be blue, green, yellow or another color. An increase in sweating might cause the condition to become more noticeable during pregnancy even though the condition is not caused by pregnancy. Have you ever heard of this rare condition?

Do you ever feel "weak in the knees" around someone you were attracted to? Chances are, Kirsty Brown from England has felt it even worse. Kirsty has a rare brain condition that causes her to collapse whenever she sees someone she's attracted to. You can imagine how that makes outings even more difficult. The disease is called cataplexy, and Kirsty has had up to five attacks per day. But sometimes it can get out of control. Bad days often include 50 attacks. That means that it's hard for her to get outside and live a normal life. This sudden loss of muscle tone leads to weakness and a loss of voluntary muscle control. It is often triggered by sudden, strong emotions such as laughter, fear, anger, stress, or excitement. Cataplexy is tied into narcolepsy, which is a chronic sleep disorder.

As a child, Neena Nizar baffled her parents and doctors. Her bones seemed unable to bear her own weight. When she didn't walk on time, doctors suspected polio or rickets. It took more than three decades to solve the mystery. In 2010 Nizar, along with her two sons, was finally diagnosed with Jansen's metaphyseal chondrodysplasia, which causes abnormal bone growth. Jansens' is caused by mutation on a gene that regulates bone growth, and as a result bones in the arms, legs and spine become deformed. It affects less than 10 people in the U.S. — and Neena hopes to be the first human participant in a drug trial this year. Have you ever heard of this condition?
