Thermal imaging and planimetry evaluation of the results of chronic wounds treatment with hyperbaric oxygen therapy.

BACKGROUND: One of the methods to treat chronic wounds is the use of hyperbaric oxygen (HBO). Objective measurement of the wound surface is an important element in the process of monitoring and predicting the progress of treatment. OBJECTIVES: The aim of the study was to evaluate the effect of hyperbaric oxygen therapy (HBOT) on ulcer wound healing in patients with chronic venous insufficiency ulcers and diabetic foot syndrome using thermal imaging and computerized planimetry. MATERIAL AND METHODS: During a 3-year period, 284 digital computer planimetry measurements were gathered from 142 patients treated for leg ulcers caused by chronic venous insufficiency and ulcers from diabetic foot syndrome at HBOT Unit of the Dr Stanislaw Sakiel Centre for Burns Treatment in Siemianowice Slaskie (Poland). Each patient took 30 HBOT sessions using a Haux multiplace HBO chamber at a pressure of 2.5 atmospheres absolute (ATA). The results of the treatment were monitored by thermovision and computerassisted planimetry measurements performed before and after HBOT. RESULTS: Both groups of patients exhibited a reduction in the surface and perimeter of the wound after HBOT. The treatment effects were also confirmed by thermal imaging. The areas calculated from thermal imaging and planimetry are different but correlated. CONCLUSIONS: It seems that a combination of thermal imaging and planimetry may enhance the diagnosis as well as provide the physician with more information about therapy effects.

A 2000 patient retrospective assessment of a new strategy for burn wound management in view of infection prevention and treatment.

Infections in burn patients are still the principal cause of complications in burn injuries. The aim of this study is to assess a new strategy for burn wound management in view of infection prevention and treatment in the experience of the Burn Treatment Center in Siemianowice Slaskie. The applied methodology involved the analysis of patient records describing the hospital's epidemiological situation between 2014 and 2016. The analysis also included the use and cost of antibiotics, silver-containing dressings, and other antiseptics relative to the number of sepsis cases, including those caused by Pseudomonas aeruginosa, as well as the mortality ratio. The total costs of prevention and treatment of infections were reduced, while the use of silver-containing dressings and antiseptics increased. The number of patients with sepsis decreased, including cases caused by P. aeruginosa, and the mortality ratio was reduced. Introducing a strategy for burn wound-oriented infection prevention and treatment in burn patients provides a number of benefits. It is also cost-effective. Using locally applied active dressings and antiseptics can be a welcome choice for often-unnecessary antibiotic therapy of a suspected or existing burn wound infection.

Different Impacts of Luminosity on Contrast Vision in Eyes with Transparent Optic Media and with Cataract Simulation.

OBJECTIVE: To evaluate the effect of luminous intensity on contrast vision under different ocular conditions. MATERIALS AND METHODS: Ninety eyes of 45 persons were included in this study as follows: 30 healthy eyes, 30 eyes with cataract simulation (using translucent glasses), and 30 myopic eyes. Contrast sensitivity was examined using 5 spatial frequencies (1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree) of sine wave contrast test optotypes for 4 light intensities (34, 68, 154, and 240 cd/m2). RESULTS: The mean linear contrast sensitivities averaged over the frequencies for each of the 4 light intensities were: healthy eyes: 59 ± 11, 72 ± 16, 79 ± 23, and 80 ± 19; myopic eyes: 52 ± 13, 67 ± 15, 73 ± 21, and 75 ± 18, and cataract simulation eyes: 15 ± 7, 21 ± 8.6, 28.7 ± 13, and 28.6 ± 13, respectively. The linear contrast sensitivities averaged over the light intensities for each of the 5 spatial frequencies were: healthy eyes: 78, 87, 117, 59, and 21; myopic eyes: 65, 84, 109, 54, and 29, and cataract simulation eyes: 37, 41, 28, 8, and 2. CONCLUSIONS: The light intensity level had a positive effect on the contrast sensitivity of the examined eyes, except for eyes with cataract simulation, where even the maximum light intensity did not improve the contrast vision. This indicates that patients with cataracts require increased contrast of text rather than brighter illumination to improve the quality of their vision.

The efficiency of burn wounds debridement with use of hydrosurgery--our experiences.

UNLABELLED: The aim of the study was to present experience of doctors from the Center for Burns Treatment in Siemianowice Slaskie who use a Versajet system. MATERIAL AND METHODS: Debridement with the use of a water jet was applied in 70 patients with IIb° /III° thermal burns in the period between 2009-2013. The corresponding evaluation involved duration of operation, locations, wound surfaces and technique of debridement after operation. Microbiological tests were also performed before and after debridement. RESULTS AND CONCLUSIONS: In the paper, its authors draw attention to the short time of debridement. The application of a water jet allows precise debridement, particularly in hardly accessible places, preparation of wounds to be covered with autologous split thickness skin graft, protection of healthy tissues.
