Abstracts from The Cold Weather Operations Conference 2021
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-11)A common effort for both military and civil healthcare is to achieve knowledge-based health care in cold weather injuries and fatal accidents in harsh arctic environment. The Cold Weather Operations Conference in November 2021, having more than 300 participants from 20 countries, was addressing the prevention and treatment of injuries and trauma care in cold weather conditions and the challenges for ... -
Botulinum Toxin A in the treatment of frostbite sequelae–results from a blinded, early-phase, comparative trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-15)Introduction: Freezing Cold Injuries (FCI) have been associated with long-term sequelae including vasospasm. The aims of the pilot study are to explore the research methodology and investigate the tolerability and safety of treatment with Botulinum Toxin-A (BTX-A) in FCI Sequelae. Methodology: This pilot study tests the logistics, the treatment setting and the follow-up procedure in an early-phase, ... -
Evaluation of dynamic infrared thermography as an alternative to CT angiography for perforator mapping in breast reconstruction: A clinical study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-15)Background: The current gold standard for preoperative perforator mapping in breast reconstruction with a DIEP flap is CT angiography (CTA). Dynamic infrared thermography (DIRT) is an imaging method that does not require ionizing radiation or contrast injection. We evaluated if DIRT could be an alternative to CTA in perforator mapping. Methods: Twenty-five patients scheduled for secondary breast ... -
Health effects of voluntary exposure to cold water–a continuing subject of debate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-22)This review is based on a multiple database survey on published literature to determine the effects on health following voluntary exposure to cold-water immersion (CWI) in humans. After a filtering process 104 studies were regarded relevant. Many studies demonstrated significant effects of CWI on various physiological and biochemical parameters. Although some studies were based on established winter ... -
Heat for wounds - water filtered infrared-A for wound healing- a review.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-29)Background:<br>Water-filtered infrared-A (wIRA) is a special form of heat radiation with high tissue penetration and a low thermal load to the skin surface. wIRA corresponds to the major part of the sun’s heat radiation, which reaches the surface of the Earth in moderate climatic zones filtered by water and water vapour of the atmosphere. wIRA promotes healing of acute and chronic wounds both by ... -
Impact on Abdominal Skin Perfusion following Abdominoplasty
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-26)Background: Wound healing problems following abdominoplasty may be a result of impaired tissue perfusion. This study evaluated the impact a standard abdominoplasty may have on abdominal skin perfusion.<p> <p>Methods: A standard abdominoplasty was performed in 16 patients. Dynamic infrared thermography (DIRT) using a mild and a stronger cold challenge was performed pre-, intra-, and postoperatively ... -
Improvement of wound healing by water-filtered infrared-A (wIRA) in patients with chronic venous stasis ulcers of the lower legs including evaluation using infrared thermography

In vivo perforasome perfusion in hemi-DIEP flaps evaluated with indocyanine-green fluorescence angiography and infrared thermography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05)Background: There are no in vivo studies that evaluate the effect of perforator dissection on the perfusion territory of a perforator (perforasome). In this study, indocyanine green fluorescence angiography (ICG-FA) and infrared thermography (IRT) were used intraoperatively to evaluate perforasome perfusion in hemi-DIEP flaps.<p> <p>Methods: Patients selected for DIEP breast reconstruction were ... -
Light-curing units used in dentistry: Effect of their characteristics on temperature development in teeth
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-25)This study aimed to investigate pulp chamber and surface temperature development using different LED light curing units (LCUs). Eight brands of LED-LCUs were tested in a laboratory bench model. The pulp chamber and surface temperature were recorded with a type T thermocouple and infrared cameras, respectively. The highest pulp chamber and surface temperature increase was 6.1±0.3°C and 20.1±1.7°C, ... -
Light-curing units used in dentistry: factors associated with heat development – potential risk for patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-01)Objectives:<br>To investigate how heat development in the pulp chamber and coronal surface of natural teeth with and without cusps subjected to irradiance using light-emitting diode (LED)–light-curing units (LCUs) is associated with (i) irradiance, (ii) time, (iii) distance, and (iv) radiant exposure.<br> Materials and methods:<br>Three different LED-LCUs were used. Their irradiance was measured ... -
A new treatment for frostbite sequelae; Botulinum toxin
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-19)Frostbite sequelae are a relevant occupational injury outcome for soldiers in arctic environments. A Caucasian male soldier suffered frostbite to both hands during a military winter exercise. He developed sensory-motor disturbances and cold hypersensitivity. Angiography and thermography revealed impaired blood flow while Quantitative Sensory Testing indicated impaired somato-sensory nerve function. ... -
Perfusion dynamics in abdominal skin after free abdominal flap breast reconstruction using internal mammary vessels as recipient vessels. A clinical study using Dynamic Infrared Thermography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-28)Background: Wound healing problems at the donor site in free abdominal flap breast reconstruction cause significant morbidity to patients. No studies have investigated what impact the use of the internal mammary artery in free abdominal flap breast reconstruction has on abdominal skin perfusion. We hypothesized that harvesting the internal mammary vessels (IMV) has a negative effect on abdominal ... -

The value of dynamic infrared thermography in pedicled thoracodorsal artery perforator flap surgery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)<p><i>Background:</i> Dynamic infrared thermography (DIRT) is a noninvasive imaging technique that can provide indirect and real-time information on skin perfusion by measuring skin temperature. Although used in flap surgery, there are no reports on its value in procedures using a pedicled thoracodorsal artery perforator (TDAP) flap. The aim of this study was to assess the usefulness of DIRT in ... -
