“…These findings expand on previous studies that have used objective thermal measurements to identify skin infections (Fujita et al, 2013;Montalto et al, 2013;Romanò et al, 2012). This study adds to existing data on thermal imaging for skin infections with the characterization of skin temperature for patients with both cellulitis and pseudocellulitis.…”

Warmth is a characteristic but nondiagnostic feature of cellulitis. We assessed the diagnostic utility of skin surface temperature in differentiating cellulitis from pseudocellulitis. Adult patients presenting to the emergency department of a large urban hospital with presumed cellulitis were enrolled. Patients were randomized to dermatology consultation (n = 40) versus standard of care (n = 32). Thermal images of affected and unaffected skin were obtained for each patient. Analysis was performed on dermatology consultation patients to establish a predictive model for cellulitis, which was then validated in the other cohort. Of those evaluated by dermatology consultation, pseudocellulitis was diagnosed in 28%. Cellulitis patients had an average maximum affected skin temperature of 34.1°C, which was 3.7°C warmer than the corresponding unaffected area (95% confidence interval = 2.7-4.8°C, P < 0.00001). Pseudocellulitis patients had an average maximum affected temperature of 31.5°C, which was 0.2°C warmer than the corresponding unaffected area (95% confidence interval = -1.1 to 1.5°C, P = 0.44). Temperature differences between sites were greater in cellulitis patients than in pseudocellulitis patients (3.7 vs. 0.2°C, P = 0.002). A logistic regression model showed that a temperature difference of 0.47°C or greater conferred a 96.6% sensitivity, 45.5% specificity, 82.4% positive predictive value, and 83.3% negative predictive value for cellulitis diagnosis. When validated in the other cohort, this model gave the correct diagnosis for 100% of patients with cellulitis and 50% of those with pseudocellulitis. A difference threshold of 0.47°C or greater between affected and unaffected skin showed an 87.5% accuracy in cellulitis diagnosis.

Background. Appendicitis is the most frequent acute abdominal disease and there are actual effective diagnostic tools for its detection. Objectives. The objective of this study was to determine whether a thermal imaging camera is a useful tool for diagnosing acute appendicitis on the basis of abdominal skin surface temperature changes which reflect intra-abdominal inflammation. Material and methods. The prospective data consisting of surgical and pathological findings of 51 patients who had undergone appendectomy between January 2013 and December 2014 with the diagnosis of acute appendicitis was collected, as well as thermal imaging camera recordings. A handheld infrared (IR) thermal imaging camera (ITIC) was used to take measurements. Results. Of the 51 patients studied, 30 were male and 21 were female. Of these, 12 had their highest temperature measurement in the epigastric and 17 in the umbilical areas. These 2 groups constituted 56.9% of the patients. Regarding the lowest temperature measurement, 10 patients had the lowest temperature in the right inguinal and 15 in the hypogastric area. These 2 numbers constituted 49% of the patients. Conclusions. This is the first report concerning the use of a thermal camera as a diagnostic tool for the evaluation of acute abdominal illness. Considering the results of our study, ITIC is not feasible as a new diagnostic tool for acute appendicitis. It may be suitable for determining superficial inflammation; however, it is not suitable for determining deep inflammation.

“…IR is able to detect skin temperature differences as low as 0.1 • C [18]. These properties were applied in several medical cases as control of postsurgical infection [19], total knee replacement [20] and dermatological treatments [21,22].…”

Setting: The infection with Mycobacterium tuberculosis gives a delayed immune response, measured by the tuberculine skin test. We present a new technique for evaluation based on automatic detection and measurement of skin infrared emission. Design: 21 subjects (57.0±17.8 yr), (7/14, M/F) with suspected tuberculosis contact were examined with an IR thermal camera, 48 hours after skin injection. Results: In 15 subjects, IR analysis was positive for tuberculine test. Mean temperature of injection area was higher, around 1 ºC, for the positive group (36.0± 0.3 ºC positive group; 35.2±1.7 ºC negative group, p<0.001, Non parametric U Mann-Whitney Test). Conclusion: IR may represent an improved estimation of tuberculosis infection, given that it does not depend on reader variability and measures the increase of heat irradiation produced by the allergic tuberculine response.
