A MACHINE used to rid hospitals of bad smells could help beat so-called superbugs.
Wigan-based firm Scent Technologies has discovered that its ST-PRO deodorising machine not only issues a pleasant aroma, but proves highly effective in killing airborne bacteria associated with MRSA and Clostridium difficile.
The discovery was made almost by chance at a hospital in Whiston, St Helens, three years ago. And following seven months of clinical trials in the burns unit at Wythenshawe Hospital, Manchester, the product is to be developed and produced by Hull company Bonus Electrical.
Prof Valerie Edwards-Jones, a microbiologist at Manchester Metropolitan University, said: "We found in the burns unit that it reduced airborne counts by 90 per cent. What surprised us was in the control room, where we didn't have any vapours, the counts were down there."
He said the results were "very encouraging."
The machine, which has also been trialled at Airedale Hospital, works by releasing an invisible vapour containing essential oils into the air.
Scent Technologies director Roy Jackson said the machine could also be used in offices and adapted for use in aircraft.

TROOPS BRING BUG TO CANADA
Hospitals Warned; Drug-resistant bacterium coming from Afghanistan
Tom Blackwell, National Post
Published: Thursday, December 13, 2007
Federal authorities are warning hospitals across the country to beware a highly drug-resistant bacterium that wounded troops are bringing back from Afghanistan -- and which could inadvertently be spread to civilian patients.
The threat posed by the resistant strain of acinetobacter underlines the health care system's general lack of readiness for such emerging infections as they arrive in the country, said a senior Public Health Agency of Canada official.
Several soldiers being treated in civilian hospitals here have already developed pneumonia from the drug-resistant strain of the bacterium, which scientists say likely originated in the Canadian-led trauma centre at Kandahar Air Field.
Hospitals are being advised by the agency to screen injured soldiers for the bug, and take infection-control precautions if they test positive.
No transmission to nonmilitary patients has yet been detected, and the bug is not seen as much of a danger to healthy people outside of hospital. The fear, however, is that the resistant strain could genetically combine with more easily treatable versions of the bacterium that are more common in Canadian intensive-care units, said Shirley Paton of the public health agency.
"We're seeing a new organism being introduced into the Canadian swamp of organisms, this one being highly resistant," she said. "If we get someone with this highly resistant strain, are the two bugs going to get together into one? ... We're quite concerned that this will start spreading and become the acinetobacter of choice in the ICUs. We're really worried about that kind of transmission."
Outbreaks that may have originated in soldiers coming from Iraq or Afghanistan have already occurred in U.S. and British hospitals.
It is "critical" that hospital infection-control officers here are aware of the issue and respond appropriately, says a recent article in the Canadian Journal of Infection Control by agency officials and outside experts.
"Ultimately, there is the risk that you end up with a brand of organism that is invulnerable to antibiotics. There is little treatment available," said Dr. Andrew Simor of Toronto's Sunnybrook Health Sciences Centre, one of the country's leading infectious-disease experts. "We have to take that seriously."
The public health agency is planning a meeting for February or March involving the Department of National Defence, provincial public health departments and major hospitals to discuss the acinetobacter problem, and newly emerged pathogens generally, Ms. Paton said.
"How do we respond to something that is just arriving? Can we track it, can we stop it? Can we hold it?" she asked. "I don't think we have the processes in place yet to really respond in a nice, efficient, everybody-knows-what-they're-doing kind of manner."
Drug-resistant microbes, sometimes called superbugs, have become an increasing cause for anxiety in Canadian hospitals, with the most common of them, Methicillin-resistant staphylococcus aureus (MRSA) being blamed for thousands of deaths a year.
Often found in soil, acinetobacter is a danger to the old and seriously ill, particularly those on breathing machines, causing wound and blood infections and pneumonia. It was detected in many American casualties of the Vietnam war, then arose again in 2003 when U.S. and British
doctors started finding it in soldiers returning injured from Iraq and Afghanistan. At least four U.S. troops have died from the infection since then.
Canadian soldiers started testing positive for the bug after their mission in southern Afghanistan began last year. The most seriously wounded are sent to civilian hospitals here for further treatment.
At least 10 with acinetobacter have shown up in ICUs, Ms. Paton said. There have been an unknown number of other "walking wounded" troops with the bug, who have not been admitted to hospitals but might have visited family physicians or military doctors, she said.
A paper published in the journal BMC Infectious Diseases in August documents the cases of four Canadian soldiers, injured by roadside bombs and other means, who ended up on ventilators in 2006. All developed a pneumonia caused by acinetobacter that was resistant even to the carbapenem class of antibiotics, virtually the last line of defence against the microbe.
Although the paper does not mention the outcomes of their cases, Dr. Simor, a co-author of the paper, said he is unaware of any deaths from acinetobacter infection of Canadian combatants.
An investigation by the Defence Department found an identical strain of the bacteria in a ventilator used at the Canadian-managed trauma hospital on Kandahar Air Field, a NATO base, suggesting that is where it originated. Measures have since been taken to try to clear the field hospital of acinetobacter, Dr. Simor said.
Meanwhile, the Forces' health services department has advised families of some returning soldiers to avoid unprotected contact with the soldier until he or she has been screened for acinetobacter, according to an article by three military doctors in a recent issue of Wound Care Canada.

Hospital 'dealing with' super bug
SERVICES at a major Brisbane hospital with an outbreak of a "super bug" will not be disrupted despite two wards being closed, its clinical chief says.
The Royal Brisbane and Women's Hospital clinical chief executive officer, Professor Keith McNeil, said staff were working to eradicate vancomycin resistant enterococcus (VRE), which is resistant to antibiotics.
On Friday, the hospital closed two 30-bed wards to new admissions when 21 patients tested positive to the bug, caused by an enterococcus bacteria which normally lives safely in the bowel.
The medical wards are being disinfected and patients are being screened as they leave.
Prof McNeil said staff had been put on extra shifts to carry out the "labour-intensive" cleaning, but said hospital was not under unusual strain.
"Bed pressures are ever present every day," he said.
"We run a balance between the number of people that are coming in and the number of people who (we) are able to discharge, so we have to put in strategies to try and maintain that throughput of patients.
"At this point in time we are not having any difficulties."
Most patients who tested positive to the bug were not sick, Prof McNeil said.
However, people with low immunity - including those with chronic disease, organ transplant recipients, diabetics and elderly people - can suffer severe infection, which is difficult to treat because of the bug's resistance.
Prof McNeil said some patients receiving dialysis had tested positive but had not come down with "overwhelming illness" as yet.
He said dealing with super bugs was now part of the day-to-day management of all hospitals.
"That's part of being a big teaching hospital," he said.
"We're not unique in this - this happens all around Australia and all around the developed world."

Key move in the war on superbugs
Michelle Fiddler,
Liverpool Echo
The Royal Liverpool and Broadgreen University Hospitals NHS trust will become one of the first in the country to use equipment with timing devices to warn staff when keyboards need cleaning.
Research into killer hospital bugs such as MRSA has found they can be spread by staff using dirty computer equipment.
The new keyboards will be used for all computers in ward areas.
Diane Wake, director of infection prevention and control, said: “The keyboards will be an additional safety measure to ensure a clean and secure, health care environment.
“These innovative products will be a great help to staff in our hospitals in the battle against infections.
“We are committed to doing everything we can no matter how small, innovative or unique it may be.”
The keyboards are completely flat, making them easier to clean, and they have hidden sensors so a red light flashes when surfaces have not been cleaned thoroughly enough.
Ms Wake said: “Good, but basic, routine clinical practices will secure victory against infections. Doing simple things well, and doing them all the time, is the guaranteed recipe for success.
“With the increasing computerisation of the NHS, the keyboards will ensure that bugs are less likely to spread when doctors and nurses move between computers and patients.
“Plus, the keyboards will be a steady reminder to keep things as clean as can be.”
The keyboards were thought up at University College London Hospitals. Research by microbiologists suggests that bacteria levels on keyboards fall by 70% if they are cleaned every 12 hours.
Keyboard covers last for two to three months. They can be a haven for bacteria as they are often difficult to clean.
