“…Analysis of the results also shows a relation between the presence of infection and foot temperature in participants aged 18-31 years with asymptomatic or incipient onychomycosis, revealing a lower temperature by almost 2 • C in positive cases of onychomycosis due to dermatophyte fungi, both in men and women, partially agreeing with the findings of Villaseñor-Mora et al (2013) [36] and Miura et al (2014) [39]. The former reported a lower temperature in nails infected by onychomycosis when the causal agent is a dermatophyte fungus in patients aged 30-75 years with type II diabetes.…”

Onychomycosis is usually diagnosed symptomatically due to the very clear signs caused by the fungus on the nail surface and structure, although the growth of the infecting agent must also be verified by culture in an enriched medium. This procedure is normally lengthy (four weeks), and samples can be contaminated, delaying the prescription of appropriate and effective treatment. Only one previous study has addressed the possibility of using thermography as a diagnostic method for onychomycosis in older people (31–70 years). The present study confirms this use but in individuals aged 18–31 years with incipient mycosis and no pathological signs. Using an FLIR E60 BX camera in a study with 214 samples, we found that men had more onychomycosis than women. We observed a relation between the presence of infection and nail temperature, with a higher temperature in yeast infections (+1 °C) and a lower temperature in dermatophyte infections (−2 °C). A higher temperature by almost 1 °C was also observed in older participants. Thermography can be viewed as a new diagnostic method in asymptomatic or incipient onychomycosis, providing the thermographic camera is sufficiently sensitive and the appropriate procedure is followed, although fungal culture is always necessary to confirm recovery after treatment.

“…The low prevalence in our study may be the result of studying a young, similarly aged university population with no symptoms. Miura et al (2014) [39] did not report a significant correlation between temperature and age. Our study, however, showed a higher temperature in older participants without infection (25-30 years) by almost 1 • C.…”

“…Miura et al 35 evaluated older adults who had subungual hyperkeratosis with and without nail dermatophytosis. They observed that the average temperature of the first toe of patients with onychomycosis was significantly lower (30.2 ± 2.6°C) than the temperature of patients who did not have this condition (32.8 ± 3.2°C, p = 0.001).…”

Introduction:The use of thermography in the medical field has been experiencing a renaissance due to advances in the infrared thermographic imaging technology, which improves thermographic equipment and promises cost saving and increased safety.Dermatology is one of the most promising fields of application among the medical areas with potential for the use of thermography.Objective: To review the findings on this subject and to describe the use of such technique for dermatology and aesthetic applications.Methods: A bibliographic survey was carried out, selecting relevant publications and guidelines, focused on monitoring medical diagnostic applications and benefits of thermography for dermatology, inflammatory skin diseases, and aesthetic applications.Results: Inflammatory skin diseases lead to changes of the IRT image. A quantification of treatment effects and monitoring changes on skin can be possible by repeated measurements over time. Conclusion:Infrared imaging is a noninvasive, powerful tool in the diagnosis and clinical management of skin conditions and monitoring of aesthetic procedures.
