The disappearing bandage that fights infections and saves lives

A bandage that gradually releases infection-fighting drugs and then dissolves once the wound has healed could help thousands of burns victims.

The high-tech dressing, pioneered at Tel Aviv University in Israel, is designed to combat the high rate of infections among burns patients.

It's estimated that as many as 70 per cent of patients with very severe burns die from infections that penetrate the body through damaged skin and wounds.

Standard care involves regular cleaning and changing of bandages, which can disrupt the healing process.

One of the major problems doctors face is that if these kinds of wounds are too dry, they won't heal fully; if they are too moist, there is a high risk of contamination by bacteria.

To get round this, Israeli scientists have developed special fibres that are woven in such a way that they can 'store' significant quantities of antibiotic drugs.

These fibres are used to make a dressing that sits on top of a burn and allows the medicine to seep slowly into the wound. 

The fibres are also biodegradable, which means that after a few days they dissolve harmlessly, removing the need to change the bandage constantly and expose the wound.

Tests show the experimental dressing can wipe out dangerous bacteria within days.

'We've developed the first wound dressing that releases antibiotics and biodegrades in a controlled manner,' says Professor Meital Zilberman, who is a member of the research team.

''Dynamic Indian of the millenium"

As Member Secretary of CLINICOM, I am so thrilled to post this information here:
''Dynamic Indian of the millenium" award conferred

Coimbatore, Jul 4 (PTI) City-based K G Foundation today conferred the 'Dynamic Indian of the Millennium' award on Arun Madhavan, a former member of Prime Minister's special committee for model village development programme under the 20-point programme.


The award, carrying a citation, was given for his 'distinguished achievements and contribution to society over the years', the foundation chairman G Bhakthavatsalam, said at a function got up as part of the celebrations of World Doctors' Day, here.

Besides being conferred a global recognition for his 'project gateway' for promoting India as an investment destination, Arun had delivered a speech at the United Nationas, Geneva, on 'A New dimension to healthcare,' in 1996, he said. The first recipient of this award was the former president, A P J Abdul K…

Isotretinoin in India: A tragedy in the offing

Isotretinoin in India: A tragedy in the offing

Isotretinoin is the drug of choice for severe calcitrant cystic acne vulgaris, which often causes scarring and depression from disfigurement. Isotretinoin has been called "the greatest medical advance of the 1980's." A majority of patients with acne are permanently cleared after a four to five months course of treatment. It has also been used off-label for a variety of oncology uses including: cervical cancer, head and neck cancer, squamous cell cancer of the skin, juvenile chronic myelogenous leukemia (CML), and neuroblastoma. However, the drug is a proved teratogen and carries a significant risk of birth defects, if it taken during pregnancy. Birth defects, which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. There is an increased risk …

An important discovery

"Gene therapy strategies will come in with a major cost advantage since DNA interference technology will act at the DNA level at lower doses, reduce toxicity and only one or two copies of the DNA"- Dr Ramanand Nadig

Genes are segments of DNA present in the chromosomes in the nucleus of every cell. Genes carry instructions for making proteins, which are then copied by special enzymes into many copies of messenger RNA (mRNA). The mRNA then comes out of the nucleus, into the body of the cell; where it goes on to create the proteins needed for everyday life. Faulty or mutated genes lead to malfunctioning proteins that cause disease. Gene expression can be blocked by restricting the ability of chromosomal DNA to be copied into RNA and made into proteins. This research has given the lead wherein the ways to correct genetic disease by changing mutant gene sequences to its normal has been …
