RESUMO
Thermography detects the infrared radiation emanated from bodies and transduces it in electrical analog signal. It has application as a complementary exam in several medical segments, including the reheating study to detect diseases like Raynaud's Phenomenon (RP). In this way, the aim of this study is to compare the heating behavior of the RP women and not diagnosed (ND) women for selection of diagnosis criteria. This retrospective study was undertaken in the city of Curitiba, Brazil. For the study, twenty-four volunteer women, with the age range of 30-70 years, were taken to participate of a survey, 12 of them have the clinical diagnostic of Secondary Raynauld's Phenomenon, and twelve women were not diagnosed. Volunteers answered an anamnesis and had the central body temperature measured. They were oriented to keep the hands free and to do not touch anything during 15 minutes for acclimatization. Then, the hands were immersed for 60 seconds in a container with water at 10 °C. New pictures were taken every five minutes during twenty minutes after the immersion. The heating curve of the right hand shows that RP women's hands are colder than ND women and are slower to reheat the temperature after cold stress. The ring (fourth finger) has a linear behavior in both hands. It was the coldest one and the slowest to reheat. Statistical difference was observed in critical times of reheating at 15 and 20 minutes after the cold stress. These results show that this finger could become a reference in studies to determine cutting points and to facilitate the clinical diagnosis of RP.

The objective of this study was to compare and correlate the Portable Ultra Sound (US) measuring technique to the skinfold measuring technique (SF) to estimate body fat percentage (%F) in young adults. Sixty military were evaluated, all males, divided in two groups: Group 1 (normal) composed by 30 military with Body Mass Index (BMI) until 24.99 kg/m(2) and Group 2 (overweight) composed by 30 military with BMI > 25 kg/m(2). Weight, height, skinfolds and ultrasound were measured in 9 points (triceps, subscapular, biceps, chest, medium axillary, abdominal, suprailiac, thigh and calf). Body fat average values obtained by skinfold thickness and ultrasound measurements were 13.25 ± 6.32 % and 12.73 ± 5.95 % respectively. Despite significant differences in measurements of each anatomical site, it was possible to verify that the total final body fat percentage calculated by both techniques did not present significant differences and that overweight group presented greater similarity between the values obtained using caliper and ultrasound equipment.

This study aimed to test a protocol of measurements based on Biophotogrammetry to Analysis of Respiratory Mechanics (BARM) in healthy children. Seventeen normal spirometric children (six male and 11 female) were tested. Their performed maneuvers of forced inspiratory vital capacity were recorded in the supine position. The images were acquired by a digital camera, laterally placed to the trunk. Surface markers allowed that the files, exported to CorelDraw® software, were processed by irregular trapezoids paths. Compartments were defined in the thoracic (TX), abdominal (AB) and the chest wall (CW). They were defined at the end of an inspiration and expiration, both maximum, controlled by a digital spirometer. The result showed that the measured areas at the inspiratory and expiratory periods were statistically different (p<0.05). It reflects the mobility of CW and compartments. In conclusion, the proposed method can identify the breathing pattern of the measured subject using images in two dimensions (2D).
