Fish skin cheaper, less painful in treating burns than bandages

Using fish skin to heal burns can be cheaper and less painful than bandages, says a scientist. Using the skin of Tilapia -- a freshwater fish -- on burns could be effective since it is rich in moisture and collagen proteins, a neurologist was quoted as saying.

Tilapia skin contains a type of collagen that is similar to the protein found in human skin. This is thought to interact with a patient's immune system to speed up healing. 

More than 300 patients worldwide have had the unusual therapy, which shows up as a fishy pattern even after it has been sterilised and the scales removed.

Although many patients can be reluctant to have fish skin wrapped around their burns, a growing number of children are actually arriving at hospital requesting the "bandage", the report said.

"The major concerns were whether the skins would subsequently come off, if the fish odour would remain," the Dr. was quoted as saying.

"With the passage of time and the success of the research, patients will arrive at the hospital wanting the treatment with the skin of the Tilapia. 

"In relation to children, the skin ends up being kind of playful, like: 'Gaining a skin and looking like a superhero'," the Dr. said.

Once sterilised, Tilapia skin undergoes radiation therapy to kill any lingering viruses. It can then be stored for up to two years if refrigerated, before simply being cut to size and placed over a burn instead of a bandage.

The skin is then removed after around one week, with no need for daily dressing changes, the report noted. 

Tilapia skin has been shown to be more resistant than the previously used pig skin, which enables it to withstand stretching.

Wounds may also close faster, with patients reporting less pain when treated with fish skin over the traditional silver sulfadiazine, according to various research.

Less painful' treatment for enlarged prostates

Men with enlarged prostates can avail of a new, "less painful" treatment, research led by an Indian-origin physician has found.

The researchers treated men with benign prostatic hyperplasia (BPH), a condition in which the prostate is enlarged but not cancerous.

The new interventional radiology treatment known as prostate artery embolisation (PAE) improved patient symptoms, regardless of the size of BPH, researchers found in a retrospective study.

"This innovative treatment offers less risk, less pain and less recovery time than traditional surgery, and we are hopeful that further research will confirm it to be an effective therapy for BPH," said lead researcher Sandeep Bagla, interventional radiologist at the Inova Alexandria Hospital in the US.

Bagla and his team examined the cases of 78 patients, who underwent prostate artery embolisation (a way of blocking abnormal blood vessels) for BPH as part of the clinicians' routine practice.

Patients were categorised into three different analysis groups based on the size of the enlarged prostate: less than 50 cubic centimetres, between 50-80 cubic centimetres and greater than 80 cubic centimetres.

The researchers evaluated the effectiveness of PAE in these patients at one, three and six months post treatment.

Ninety-six percent of cases (75 of 78) were considered technically successful, with both blood vessels leading to the enlarged prostate blocked by PAE treatment.

The researchers found improvement in symptoms and quality of life, as measured by the American Urological Association Symptom Index, in all three patient groups.

The findings were presented at the ongoing Society of Interventional Radiology's 40th Annual Scientific Meeting at the Georgia World Congress Center in Atlanta.
