Our scientists and medical experts have made great strides in combating many diseases and ailments that afflict the human body.

But there are still mysteries in a large number of fields.

One such gap in our knowledge involves a genetic disorder called Epidermolysis Bullosa, which affects just 12-15 children every year.

The skin on those who suffer from it does not knit together properly, leading to severe blistering.

The parents of one victim, four-year-old Simon Tredwell, have to spend two hours a day bursting up to 150 blisters to keep the condition under control.

It causes Simon pain and discomfort, and severely disrupts family life.

With so few children suffering from the disorder, research into the cause and possible cure no doubt has a low priority.

But for those who suffer from it, it is a horrendous burden to carry.

The Tredwell family hope that by publicising their son's case, they will draw attention to a small charity called DebRA, which supports those with the condition and funds vital research. We wish them well.
