The aim of this study was to compare morphological aspects of basal cell carcinoma (BCC) as assessed by two different imaging methods: in vivo reflectance confocal microscopy (RCM) and multiphoton tomography with fluorescence lifetime imaging implementation (MPT-FLIM). ⋯ According to our data, both methods are suitable to image BCC's features. The concordance between MPT-FLIM and RCM is high, with some limitations due to the technical differences between the two devices. The hardest difficulty when comparing the images generated by the two imaging modalities is represented by their different field of view.

Deep burn assessment made by clinical evaluation has an accuracy varying between 60% and 80% and will determine if a burn injury will need tangential excision and skin grafting or if it will be able to heal spontaneously. Laser Doppler Imaging (LDI) techniques allow an improved burn depth assessment but their use is limited by the time-consuming image acquisition which may take up to 6 min per image. ⋯ Technological improvements of LDI technology leading to a decreased image acquisition time and reliable burn depth assessment allow the routine use of such devices in the acute setting of burn care without interfering with the patient's treatment. Rapid and reliable LDI technology may assist clinicians in burn depth assessment and may limit the morbidity of burn patients through a minimization of the area of surgical debridement. Future technological improvements allowing the miniaturization of the device will further ease its clinical application.

Comparative Study
A comparison between laser-doppler imaging and colorimetry in the assessment of scarring: "a pilot study".
This cross-sectional pilot-study investigated the reproducibility of the LDI (Moor-LDI-B2; Moor Instruments) and the chromameter (Minolta chromameter CR-300) when used in scar assessment. ⋯ This pilot-study with a limited number of measurements shows a moderate reproducibility of the LDI compared to the chromameter measurements, in the assessment of respectively flux and redness in scars.

Acne is a skin disease which accompanies pathological and morphological changes. Although acne severity is scored by clinicians based on pathological status, aesthetic aspect of acne symptom is also concerned by patients. This study was conducted to examine the usefulness of a 3D image analysis method for the cosmetic efficacy evaluation of an anti-acne cream. ⋯ The current study demonstrated that the 3D image-based analysis of the skin may be useful for the quantification of acne symptoms of cosmetic relevance.

Infrared thermal images in patients suffering from herpes zoster (HZ) may exhibit thermal asymmetry due to the unilateral distribution of HZ lesions. This study examined the usefulness of infrared thermography in acute HZ as a predictor for the development of postherpetic neuralgia (PHN). ⋯ Temperatures of the lesions were found to be warmer than the control side in most patients with acute HZ. We compared the patient group who developed PHN with those who did not. In univariate analysis, patients with PHN were older (P=0.004), had a higher VAS score for pain (P<0.001), higher ΔT (P<0.001) and larger BSA (P=0.001). In logistic regression analysis to identify independent risk factors of PHN, older age (>60 years old) and ΔT more than 0.5 °C were found to be statistically significant.
