Thermography study of skin response due to whole‐body cryotherapy

Purpose: Thermography and contact thermometry were used to study the influence of body mass index (BMI) on the lowering of skin temperature caused by whole‐body cryotherapy.

Monitoring of whole body cryotherapy effects by thermal imaging: preliminary report

In whole body cryotherapy the whole human body is exposed to low temperature below -100 degrees C in a special room called cryogenic chamber for a very short period of time (2-3 minutes). The impact of cold can cause many different biochemical and physiological reactions of the organism. The skin temperature response due to whole body cryotherapy was studied by means of infrared measurements. The thermograms of chosen body parts of patients suffering from low back pain were performed before and after whole body cooling on the 1(st), 5(th) and the last (10(th)) day of medical treatment. Infrared imaging performed after cold impact owing to the enhancement of the skin temperature profile may reveal a slight decrease of the inflammatory states as a result of the 10 sessions of cryotherapy.

May thermal imaging be useful in cyclist endurance tests

Thermovision is a completely non-invasive and easy-to-perform method of imaging, and it is becoming useful not only in different modalities of clinical medicine, but also in sports medicine. However, it seems that thermal imaging may also find some use in training. That is why the aim of these studies is to compare temperature parameters with data obtained from specialist equipment, which uses monitoring to choose organism parameters during the endurance test and also to determine the efficiency level. In this study, we also try to estimate body metabolism, using a modified formula of Kleiber’s law. We describe how metabolism changes during efficiency tests and compare these changes with parameters checked by an ergospirometer. All studies were performed by thermovision camera (Flir Systems E60). Results of the study showed that thermal imaging may be useful in sports medicine as a helpful method in efficiency evaluation. We obtained a high correlation between the standard parameters used in efficiency tests and the parameters derived from thermal imaging, which may suggest the possibility of using thermovision as an additional method in the planning of training cycles, and its effects.

Does the temperature gradient correlate with the photodynamic diagnosis parameter numerical colour value (NCV)

BACKGROUND Photodynamic diagnosis (PDD) as well as thermovision belong to the category of non-invasive optical diagnosis techniques. Among many different skin cancer diseases, basal cell carcinoma (BCC) is the most frequently occurring one (almost 95% of all skin tumours). In contrast, seborrhoeic keratosis represents almost 70% of benign skin tumours. In this paper we present infrared thermography as an additional method, combined with PDD, to show the differentiation between these two skin mutations. METHODS The photodynamic diagnosis studies were performed by using the autofluorescence diagnosis system Xillix Onco. As an additional non-invasive diagnosis technique, thermovision studies were performed. Thermal imaging was done by using a Thermovision Camera A40M with a sensitivity of 0.07K. The thermograms of the chosen areas were performed in a special room with a temperature of 22.5±1°C. All patients were treated in the Chair and Clinic of Internal Diseases, Angiology and Physical Medicine in Bytom. Thirteen skin lesions were studied: 9 diagnosed as basal cell carcinoma and 4 as seborrhoeic keratosis. All skin lesions were confirmed in histopathological examinations. RESULTS AND CONCLUSIONS The results of the studies revealed significant differences in skin thermal mapping between patients suffering from basal cell carcinoma and seborrhoeic keratosis. It appears that benign skin lesions are characterised by a lower mean temperature than the surrounding healthy skin. To the contrary, cancerous skin mutations appeared on the thermal map at a higher mean temperature. Thermal images for the chosen skin lesions and temperature parameters derived from the thermograms are contiguous with the photodynamic diagnosis results and may give some additional diagnostic information.

Can Whole-Body Cryotherapy with Subsequent Kinesiotherapy Procedures in Closed Type Cryogenic Chamber Improve BASDAI, BASFI, and Some Spine Mobility Parameters and Decrease Pain Intensity in Patients with Ankylosing Spondylitis?

The present study investigated whether whole-body cryotherapy (WBC) procedures could potentially have more beneficial effects on index of BASDAI and BASFI, pain intensity, and spine mobility parameters: Ott test, modified Schober test, chest expansion in ankylosing spondylitis (AS) patients, than kinesiotherapy procedures used separately. AS patients were exposed to a cycle of WBC procedures lasting 3 minutes a day, with a subsequent 60 minutes of kinesiotherapy or 60 minutes of kinesiotherapy only, for 10 consecutive days excluding weekend. After the completion of the cycle of WBC procedures with subsequent kinesiotherapy in the AS patients, BASDAI index decreased about 40% in comparison with the input value, whereas in the group of patients who received only kinesiotherapy it decreased only about 15% in comparison with the input value. After the completion of the treatment in the WBC group, BASFI index decreased about 30% in comparison with the input value, whereas in the kinesiotherapy group it only decreased about 16% in comparison with the input value. The important conclusion was that, in WBC group with subsequent kinesiotherapy, we observed on average about twice better results than in the group treated only by kinesiotherapy.

Increased Levels of Oxidative Stress Markers, Soluble CD40 Ligand, and Carotid Intima-Media Thickness Reflect Acceleration of Atherosclerosis in Male Patients with Ankylosing Spondylitis in Active Phase and without the Classical Cardiovascular Risk Factors

Objective The primary aim of the study was to assess levels of oxidative stress markers, soluble CD40 ligand (sCD40L), serum pregnancy-associated plasma protein-A (PAPP-A), and placental growth factor (PlGF) as well as carotid intima-media thickness (IMT) in patients with ankylosing spondylitis (AS) with active phase without concomitant classical cardiovascular risk factors. Material and methods The observational study involved 96 male subjects: 48 AS patients and 48 healthy ones, who did not differ significantly regarding age, BMI, comorbid disorders, and distribution of classical cardiovascular risk factors. In both groups, we estimated levels of oxidative stress markers, lipid profile, and inflammation parameters as well as sCD40L, serum PAPP-A, and PlGF. In addition, we estimated carotid IMT in each subject. Results The study showed that markers of oxidative stress, lipid profile, and inflammation, as well as sCD40L, PlGF, and IMT, were significantly higher in the AS group compared to the healthy group. Conclusion Our results demonstrate that ankylosing spondylitis may be associated with increased risk for atherosclerosis.

Thermal imaging application in chronic venous disease

Thermal imaging was used for the estimation of lower-limb primary chronic venous diseases connected with an insufficiency of superficial veins. The current study was performed by means of a Thermovision A40 camera. The curves of the chosen regions of interest were performed in a research room with a stabilized temperature. Curves of the lower extremities showed that the patients suffered from a venous insufficiency characterized by a higher skin temperature connected with pathological changes in the veins. Changes seen in the lower extremities skin thermal map may be associated with blood stasis, inflammatory states and swelling. The differences in temperature distribution are due to a correlation between the medical diagnosis and the parameters obtained from duplex scanning. The results of the thermal imaging showed differences between patients’ health may suggest that a thermovision of lower extremities venous diseases can be very useful in medical diagnosis. The correlation was obtained from temperature parameters and duplex scanning. The parameters may suggest that thermovision diagnostics may be useful as a complementary method in the diagnosis of chronic venous diseases in the lower extremities.

Whole-Body Cryotherapy Decreases the Levels of Inflammatory, Oxidative Stress, and Atherosclerosis Plaque Markers in Male Patients with Active-Phase Ankylosing Spondylitis in the Absence of Classical Cardiovascular Risk Factors

Objective The aim of the study was to estimate the impact of whole-body cryotherapy (WBC) on cardiovascular risk factors in patients with ankylosing spondylitis (AS). Material and Methods We investigated the effect of WBC with subsequent kinesiotherapy on markers of inflammation, oxidative stress, lipid profile, and atherosclerosis plaque in male AS patients (WBC group). To assess the disease activity, the BASDAI and BASFI were also calculated. The results from the WBC group were compared with results from the kinesiotherapy (KT) group. Results The results showed that in the WBC group, the plasma hsCRP level decreased without change to the IL-6 level. The ICAM-1 level showed a decreasing tendency. The CER concentration, as well as the BASDAI and BASFI, decreased in both groups, but the index changes of disease activity were higher in the WBC than KT patients. Additionally, in the WBC group, we observed a decrease in oxidative stress markers, changes in the activity of some antioxidant enzymes and nonenzymatic antioxidant parameters. In both groups, the total cholesterol and LDL cholesterol, triglycerides, sCD40L, PAPP-A, and PLGF levels decreased, but the parameter changes were higher in the WBC group. Conclusion WBC appears to be a useful method of atherosclerosis prevention in AS patients.

Proposal of thermal imaging application in photodynamic therapy—Preliminary report

There are many different skin lesions that manifest a skin temperature gradient. Basal cell carcinoma (BCC) is the most frequently occurring type of malignant skin lesion (almost 95% of all skin tumors). BCC is sometimes treated by using photodynamic therapy which is very well tolerated by patients and provides good results, especially in superficial skin layer lesions. The results of our studies showed significant changes in the area of temperature gradient due to photodynamic therapy. It seems that the ability to acquire knowledge of such area changes may provide additional useful information to physicians. The increase of observed isotherm area in comparison to lesion size on the skin was a few times higher. It may suggest the range of areas where the metabolism processes take place. Due to the accumulation of photosensitivity only in tumor cells, we theorize that such a large region of increased metabolism observed during therapy may be connected with a larger range of tumor cells than was previously predicted through diagnosis. However, it should be noted that the region can be much bigger due to the existing heat transfer. The results obtained have a potential meaning in describing the range of chemical and physiological processes occurring during photodynamic therapy.

Whole-Body Cryostimulation as an Effective Method of Reducing Oxidative Stress in Healthy Men

BACKGROUND Whole-body cryostimulation (WBC) is the therapeutic exposure of the total human body (without underwear) to a very low temperature (below -100°C) for 120-180 s. Currently, WBC is used more frequently not only in the treatment of patients suffering from various diseases, but also by healthy people as a wellness method. OBJECTIVES The aim of this research is to evaluate the impact of WBC procedures on oxidative stress parameters in healthy men. MATERIAL AND METHODS The study involved 32 healthy male subjects who were randomly divided into 2 groups: 16 men exposed to WBC procedures with subsequent kinesiotherapy (WBC group) and 16 men exposed only to kinesiotherapy procedures (KT group). Depending on the group, the subjects were exposed to 10 daily WBC procedures lasting 3 min, with a subsequent 60-min of kinesiotherapy, or exclusively to kinesiotherapy. In subjects from both groups, a day before the beginning of a cycle of treatment and a day after its completion, the level of selected indicators of oxidative stress and non-enzymatic antioxidants, as well as the activity of antioxidant enzymes in serum, plasma and erythrocyte lysates were determined. RESULTS In the WBC group subjects, we recorded a statistically significant decrease in the concentrations of most of the parameters of oxidative stress with an accompanying increase in plasma concentrations of non-enzymatic antioxidants (total antioxidant status and uric acid). We recorded no significant changes in the activities of antioxidant enzymes (plasma total superoxide dismutase (SOD) and its isoenzymes SOD-Mn and SOD-ZnCu, erythrocyte catalase, glutathione peroxidase and glutathione reductase). CONCLUSIONS The results we obtained confirmed that WBC decreases oxidative stress in healthy men.
