Exploring the potential of rapid evaporative ionization mass spectrometry (Intelligent Knife) for point-of-care testing in aortic surgery.

Eur J Cardiothorac Surg 2021 Apr 11. Epub 2021 Apr 11.

Liverpool Centre for Cardiovascular Science, Liverpool, UK.

Objectives: Many intraoperative decisions regarding the extent of thoracic aortic surgery are subjective and are based on the appearance of the aorta, perceived surgical risks and likelihood of early recurrent disease. Our objective in this work was to carry out a cross-sectional study to demonstrate that rapid evaporative ionization mass spectrometry (REIMS) of electrosurgical aerosol is able to empirically discriminate ex vivo aneurysmal human thoracic aorta from normal aorta, thus providing supportive evidence for the development of the technique as a point-of-care test guiding intraoperative surgical decision-making.

Methods: Human aortic tissue was obtained from patients undergoing surgery for thoracic aortic aneurysms (n = 44). Read More

Clinoptilolite augmented electrocoagulation process for the reduction of high-strength ammonia and color from stabilized landfill leachate.

Water Environ Res 2021 Apr 19;93(4):596-607. Epub 2020 Oct 19.

School of Materials and Mineral Resources Engineering, Universiti Sains Malaysia, Nibong Tebal, Malaysia.

The high-strength leachate produced from sanitary landfill is a serious issue around the world as it poses adverse effects on aquatic life and human health. Physio-chemical technology is one of the promising options as the leachate normally presents in stabilized form and not fully amendable by biological treatment. In this research, the effectiveness of natural zeolite (clinoptilolite) augmented electrocoagulation process (hybrid system) for removing high-strength ammonia (3,442 mg/L) and color (8,427 Pt-Co) from naturally saline (15 ppt) local landfill leachate was investigated.

Novel Energy Devices in Head and Neck Robotic Surgery - A Narrative Review.

Robot Surg 2020 23;7:25-39. Epub 2020 Apr 23.

Faculty of Medicine, Imperial College London, London, UK.

The advent of trans-oral robotic surgery (TORS) has facilitated removal of tumors previously deemed unresectable, by providing access to the deep structures of the head and neck. Despite this, the wider dissemination of TORS has been restricted due to issues with line of access, as the da Vinci robot was never designed with head and neck surgery in mind. Flexible instruments and novel energy delivery devices offer great potential in overcoming some of the existing challenges surrounding TORS. Read More

Breast reconstruction in a patient with an implanted deep brain stimulator.

JPRAS Open 2020 Jun 11;24:56-59. Epub 2020 Apr 11.

Department of Plastic and Reconstructive Surgery, Nagoya City University Graduate School of Medical Sciences and medical School, Nagoya, Japan.

Deep brain stimulators (DBSs) are sometimes used to treat refractory movement disorders such as Parkinson's disease. When DBSs are implanted in a subcutaneous pocket in the chest region, breast reconstruction becomes a challenge because monopolar electrocautery can lead to DBS dysfunction or brain tissue damage caused by heat. We report a patient with a DBS who underwent one-stage implant-based breast reconstruction. Read More
