h i g h l i g h t sStandardizing the acclimatization time is crucial for a right T SK assessment by IRT. Time for reaching T SK balance in rest is different for young men and women. 10 min is enough for acclimatization when the external temperatures are not extreme. a r t i c l e i n f oArticle history: Received 6 November 2012 Available online 3 March 2014Keywords: Thermoregulation Thermography Thermal imaging Temperature a b s t r a c t Thermography for scientific research and practical purposes requires a series of procedures to obtain images that should be standardized; one of the most important is the time required for acclimatization in the controlled environment. Thus, the objective of this study was to identify the appropriate acclimatization time in rest to reach a thermal balance on young people skin. Forty-four subjects participated in the study, 18 men (22.3 ± 3.1 years) and 26 women (21.7 ± 2.5 years). Thermographic images were collected using a thermal imager (Fluke Ò ), totaling 44 images over a period of 20 min. The skin temperature (T SK ) was measured at the point of examination which included the 0 min, 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20. The body regions of interest (ROI) analyzed included the hands, forearms, arms, thighs, legs, chest and abdomen. We used the Friedman test with post hoc Dunn's in order to establish the time at rest required to obtain a T SK balance and the Mann-Whitney test was used to compare age, BMI, body fat percentage and temperature variations between men and women, considering always a significance level of p < 0.05. Results showed that women had significantly higher temperature variations than men (p < 0.01) along the time. In men, only the body region of the abdomen obtained a significant variance (p < 0.05) on the analyzed period, both in the anterior and posterior part. In women, the anterior abdomen and thighs, and the posterior part of the hands, forearms and abdomen showed significant differences (p < 0.05). Based on our results, it can be concluded that the time in rest condition required reaching a T SK balance in young men and women is variable, but for whole body analysis it is recommended at least 10 min for both sexes.

“…It has been reported that PpIX metabolism is faster at higher temperatures 31,32 . Skin temperature varies at different body sites and can be displayed with infrared imaging cameras 33 [http://www.rnhrd.nhs.uk/page/92]. Typical temperatures of the head and the neck have found to be 35-37°C 34,35 , the lower leg and the "edge" areas of the feet and the hands have lower temperatures of 30-33°C.…”

3 HighlightsWe developed a handheld device and a time course method for fluorescence imagingThe device can be used to study PpIX formation in healthy and diseased skin PpIX fluorescence grows throughout the 3 hours prior to treatmentThe fluorescence intensity varies between diagnoses and individuals The fluorescence depends on the body site, possibly due to differences in temperature 4 Abstract Background

“…4,18 Some studies have shown the significance of thermography in the estimation of some painful conditions, including radiculopathy. 4,8,10,[18][19][20] Contrary to the methods that estimate radiculopathy on the basis of structural changes in the spine or changes in spinal nerve root function, IRT assesses radiculopathy based on a vasomotor dysfunction. Its advantage in comparison with other methods is its non-invasive, painless nature that does not expose the patient to ionising radiation and is also easy to use.…”
