(Press-News.org) Robust evidence exists for some wound care interventions, but there are still gaps in current knowledge requiring international consensus and further high-level clinical evidence, according to a paper published online by BJS, the British Journal of Surgery.
Researchers analysed the findings of 44 Cochrane Systematic Reviews (CSRs) published by the Cochrane Wounds and Peripheral Vascular Disease Groups up to June 2011. The reviews covered CSRs on acute wounds and chronic wounds such as venous, pressure, diabetic and arterial ulcers.
This enabled them to identify a number of findings that provide strong clinical evidence for treating specific wound issues.
"Acute and chronic wounds pose a substantial problem in different healthcare settings including emergency departments, nursing homes, home care and family doctor practices" says co-author Dr Dirk Ubbink, from the Academic Medical Centre in Amsterdam, The Netherlands.
"Because wounds have a considerable impact on patient health, death, daily functioning and quality of life, they deserve high-quality local and systemic treatment.
"Ideally wound treatment decisions should be based on the best available evidence, integrated with patients' concerns and priorities and fine-tuned by the local resources and skills. In reality, however, treatment decisions are generally based on the personal opinions, experiences and preferences of healthcare professionals, which can vary widely. This is partly due to the overwhelming amount of literature available, which often shows conflicting results.
"Our meta-review of the CSRs aims to help clinicians make evidence-based decisions by analysing studies of both local and systemic open wound care."
The meta-review covered 13 CSRs on venous ulcers, 12 on acute wounds, seven on pressure ulcers, six on diabetic ulcers, five on arterial ulcers and five on miscellaneous chronic wounds.
Findings were placed into five categories, based on strong evidence of effect/no effect, limited evidence of effect/no effect and no evidence either way.
Strong findings included:
Acute wounds
Using antibiotics to prevent infections after dog bites is ineffective unless the bites are on the hands.
Systemic treatment with therapeutic touch does not have any additional effect on wound healing compared to placebo or non-treatment after minor surgery.
Cleansing pin site wounds using saline, alcohol, hydrogen peroxide or antibacterial soap to prevent infections is no more effective than no cleansing.
Topical honey reduces wound healing time when compared to film or gauze-based dressings for burns.
Silver sulfadiazine should not be used for burns as trials show this can delay wound healing and increase pain and infection rates.
Drinking quality tap water is better for cleansing lacerations and acute soft tissue wounds than sterile saline solutions.
Chronic wounds
Systemic treatment of venous ulcers with pentoxyfylline increases complete wound healing and compression therapy, using high compression, multi-component systems or elastic bandages, is most effective.
Using hyperbaric oxygen therapy decreases major amputations in diabetic ulcers and local hydrogels should be used after debridement to promote wound healing.
Systemic prostanoids should be used to relieve rest pain and improve ulcer healing in patients with critical leg ischaemia and spinal cord stimulation improves limb salvage.
Using high-specification foam mattresses and low air loss mattresses can prevent pressure ulcers on the ward and pressure-relieving overlays are recommended on operation tables. Using local therapeutic ultrasound is not recommended for healing pressure ulcers.
"Our meta-review drew 33 conclusions with strong evidence and 18 conclusions with fairly strong evidence from the CSRs we studied" says lead author Dr Fleur Brölmann. "Evidence was not available or insufficient in the remaining 58."

Climate in northern Europe reconstructed for the past 2,000 years
2012-07-10
An international team that includes scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings. Professor Dr. Jan Esper's group at the Institute of Geography at JGU used tree-ring density measurements from sub-fossil pine trees originating from Finnish Lapland to produce a reconstruction reaching back to 138 BC. In so doing, the researchers have been able for the first time to precisely demonstrate that the long-term trend over the past ...
Frankincense as a medicine
2012-07-10
Jena (Germany) It was one of the gifts of the Magi – in addition to myrrh and gold they offered frankincense to the newly born baby Jesus. Since the ancient world the aromatic fragrance of burning Boswellia resin has been part of many religious ceremonies and is still used as a means to indicate special festive atmosphere in the church today. But frankincense can do much more: "The resin from the trunk of Boswellia trees contains anti-inflammatory substances," Professor Dr. Oliver Werz of the Friedrich Schiller University Jena (Germany) says. The chair of Pharmaceutical ...
America's poorly-educated spend less time-off with family or friends, study finds
2012-07-10
Despite having more leisure time overall, stressed-out Americans report having less 'quality time' to enjoy themselves, particularly those with little or no education.
This is according to the findings of a new paper entitled Leisure Inequality in the US: 1965-2003, from Queen Mary, University of London, the University of Oxford and the University of Zaragoza.
The research offers insights on how leisure inequality across educational groups has evolved in the last four decades in the United States in contrast with the inequality in wages and expenditure over the same ...
Europe clears the air
2012-07-10
Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade. More than 15 years of atmospheric observations have revealed trends in air quality.
As the world's population increases, economies in many countries are also growing and populations are concentrating in large cities. With the use of fossil fuels still on the rise, pollution in large cities is also increasing.
Nitrogen dioxide is an important pollutant in the troposphere, the lowest portion of our atmosphere.
Satellite observations ...
A new species of wirerush from the wetlands in northern New Zealand
2012-07-10
The northern part of the North Island of New Zealand is marked at approximately 38° S latitude by a distinct ecological boundary known as the "kauri line". This region forms the southern distributional limit of many plants and is the warmest part of New Zealand. A number of endemic plants are found there. Ecologists have recently discovered a new species of wirerush from peatlands north of the "kauri line".
Wetlands serve vital ecological functions by providing wildlife habitat, carbon storage, nutrient regulation and water balance. New Zealand has a number of wetland ...
Sounds of northern lights are born close to ground
2012-07-10
For the first time, researchers at Aalto University in Finland have located where the sounds associated with the northern lights are created. The auroral sounds that have been described in folktales and by wilderness wanderers are formed about 70 meters above the ground level in the measured case.
Researchers located the sound sources by installing three separate microphones in an observation site where the auroral sounds were recorded. They then compared sounds captured by the microphones and determined the location of the sound source. The aurora borealis was seen at ...

Lipid helps cells find their way by keeping their 'antennae' up
2012-07-10
AUGUSTA, Ga. – A lipid that helps lotion soften the skin also helps cells find and stay in the right location in the body by ensuring they keep their "antennae" up, scientists report.
Each cell has an antenna, or cilium, that senses the environment then determines where to go and what to do when it arrives, said Dr. Erhard Bieberich, biochemist at the Medical College of Georgia at Georgia Health Sciences University.
"A cell is blind; it does not see, it does not feel; it doesn't know where it is," Bieberich said. "It needs to have an organelle that senses where it ...
Handlebar level can affect sexual health of female cyclists
2012-07-10
A new study published in The Journal of Sexual Medicine reveals that handlebar position is associated with changes in genital sensation in female cyclists.
Led by Marsha K. Guess, MD, MS, of Yale University School of Medicine, researchers evaluated bicycle set-up in terms of the relationship between the seat and the handlebars. 48 competitive women cyclists were studied.
Researchers measured saddle pressures and sensation in the genital region to see if placing handlebars in different positions affects pressure and sensation in the genital region. Results showed that ...
Lower iron levels seen in newborns of obese mothers
2012-07-10
BOSTON (July 9, 2012) -- A growing number of studies imply that children born to obese mothers face health problems stemming from the womb.
New research from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University and The Mother Infant Research Institute at Tufts Medical Center suggests that low iron status is among these health problems, according to an analysis of maternal hepcidin, a hormone that is key in keeping iron levels balanced.
The study enrolled 15 obese pregnant women with body mass index (BMI) greater than 30 and 15 healthy weight ...
