New tool could aid breast cancer surgery

December 5, 2016

ADELAIDE, Australia: Australian researchers have developed an optical fibre probe that can distinguish between breast cancer tissue and normal tissue — potentially allowing surgeons to be much more precise when removing cancerous tissue. The device could help prevent follow-up surgery, currently required by 15 to 20 per cent of breast cancer surgery patients, when all the cancer is not removed.

Interview: “Antibiotic resistance is a serious health issue”

November 28, 2016

The use of antibiotics is essential in modern medical treatments, yet frequent misuse has reduced their effectiveness. This year’s World Antibiotic Awareness Week (WAAW), held from 14 to 20 November, sought to increase public understanding of the issue. DT Online spoke with Dr Paul Sambrook, Chairman of the Dental Therapeutics Committee of the Australian Dental Association (ADA), about WAAW’s purpose and what dental professionals can do to combat antimicrobial resistance.

Barriers to cleft lip and palate surgery persist in Vietnam

November 10, 2016

LOS ANGELES, USA: Charitable organisations perform more than 80 per cent of cleft lip and cleft palate surgeries in Vietnam, a new study by US researchers has found. According to the scientists, this reflects the complex and persistent barriers to surgical care in low- to middle-income countries (LMICs) and shows that charitable missions remain a critical source of access to surgical care for these states.

Sedative may prevent delirium after surgery

October 25, 2016

BEIJING, China/LONDON, UK: A mild sedative could greatly reduce the risk of people experiencing delirium after an operation and help the brain recover and reset, according to new research findings. A study conducted by scientists at Imperial College London and Peking University First Hospital has suggested that sedating patients after they have undergone an operation may reduce the risk of postoperative delirium by up to 65 per cent.

New device improves surgeon’s sensitivity during operations

September 5, 2016

HIROSHIMA, Japan: A small vibrating device added to surgical tools could improve surgeons’ sensitivity to different tissue shapes and textures in their patients’ bodies. Japanese researchers have designed the PZT Actuator to attach to any existing hand-held surgical tool for immediate use, without doctors requiring extra training.

Frequent dental scaling might reduce infection risk after knee replacement

August 5, 2016

TAINAN, Taiwan: Oral bacteria that enter and spread through the bloodstream have been found to cause about 10 per cent of peri-prosthetic joint infections after total knee arthroplasty (TKA). Therefore, TKA patients are often advised to pay special attention to their oral health. A team of Asian researchers has now found that frequent dental scaling might reduce the risk of infection after TKA.

Researchers develop handheld surgical pen that prints human stem cells

April 18, 2016

MELBOURNE, Australia: 3-D bioprinters that can be used to print cells layer by layer to build up artificial tissue for implantation are currently revolutionising tissue engineering. In a landmark proof of concept experiment, Australian researchers have used a handheld 3-D printing pen to draw human stem cells in freeform patterns with extremely high survival rates. The BioPen is designed to allow surgeons to sculpt customised cartilage implants during surgery.

Australian researchers to start trials of fully implantable bionic eye

February 5, 2016

SYDNEY, Australia: A team of researchers at the University of New South Wales (UNSW) in Sydney has developed the first fully implantable bionic eye, Phoenix99, which is expected to restore vision far more effectively than do current vision restoration devices. After successfully testing the technology in preclinical work and receiving substantial funding from the National Health and Medical Research Council, the scientists are now ready to begin trials in human implantation.

Aussie scientists develop new coating to improve implants

November 27, 2015

MELBOURNE, Australia: Prebiotic compounds, whose origin can be traced back billions of years, have been studied intensively since their discovery several years ago.

Less-invasive surgery may not be best option for rectal cancer

October 8, 2015

SYDNEY, Australia: A new study by Australian researchers has compared open surgery and laparoscope-assisted keyhole surgery in order to assess which procedure is more successful in the removal of rectal tumours. According to the researchers, concerns remain about the applicability of minimally invasive surgery to rectal cancer and more research is needed to establish the case for the routine use of laparoscopic surgery in this area.
