Thermoregulation disorders are associated with Body temperature fluctuation. Both hyper- and hypothermia are evidence of an ongoing pathological process. Contralateral symmetry in the Body heat spread is considered normal, while asymmetry, if above a certain level, implies an underlying pathology. Infrared thermography (IRT) is employed in many medical fields including ophthalmology. The earliest attempts of eye surface temperature evaluation were made in the 19 century. Over the last 50 years, different authors have been using this method to assess ocular adnexa, however, the technique remains insufficiently studied. The reported IRT data is often contradictory, which may be due to heterogeneity (in terms of severity) of patient groups and disparities between research parameters.
Infrared thermography is one of the widely used non-invasive diagnostic methods. While the procedure is mainly used for early malignant tumor diagnostics, a potential application for thermography was proposed in cardiovascular, skin, autoimmune diseases, arthritis, Reynaud's syndrome, burns, surgery and therapeutic treatment monitoring. The method of thermographic evaluation has not changed significantly since the end of 20th century. In this study we attempted to characterize the influence of skin capillary blood flow on surface temperature recuperation following local hypothermia. To improve sensitivity and standardize the procedure we developed a study protocol that involves minimizing or excluding the influence of external factors on study results. An original applicator was used to apply dosed hypothermia. Massive porcine tissue block was chosen as a passive model without active heat and mass transfer but with heat capacity, structure and heat dissipation characteristics similar to human tissues. 51 healthy volunteers were assigned to control group, while 16 patients with diabetes mellitus constituted the main study group. Cumulative temperature difference was calculated in all cases. It was 121,8 ± 70,8 °С×s in the control group, 95,6 ± 54,4 °С×s in the main study group and 307,2 ± 43,4 °С×s in the passive model. Based on the study results, we made the following conclusions: absence of heat and mass transfer in the passive model complicates heat balance recuperation due to layered structure of the skin; heat balance recuperation curve is an individual parameter and is not influenced by age or gender. РезюмеМетод дистанционной инфракрасной термографии -один из неинвазивных диагностических методов, широко применяемых в медицине. Помимо применения для ранней диагностики злокачественных новообразований было предложено его использование при сосудистых заболеваниях, кожных болезнях, ревматических заболеваниях, артритах, синдроме Рейно, ожогах, хирургии, мониторинге эффективности терапевтического лечения и др. Необходимо отметить, что с конца прошлого столетия технический уровень выполнения тестов существенно не менялся. В своей работе мы попытались охарактеризовать вклад капилляров системы кровоснабжения кожи в динамику восстановления температуры поверхности после локальной гипотермии. Для повышения чувствительности и стандартизации метода мы разработали протокол исследования, предполагающий максимальную стандартизацию условий внешней среды или исключение их влияния. Для дозированной локальной холодовой нагрузки использовали оригинальный аппликатор. В качестве пассивной тепловой модели с отсутствием активного тепломассопереноса, но с близкими к человеческим тканям свойствами теплоемкости, структурой и характером кондуктивного перераспределения тепла, была выбрана модель на основе массивного блока тканей свиньи. Группу контроля составили условно здоровые добровольцы. В группу контроля вошли 51 человека, в группу больных диабетом II типа -16 человек. Нами получены показатели интегральной разницы температур.
