Association between Washing Residue on the Feet and Tinea Pedis in Diabetic Patients

Figure 1

Representative images of patients’ feet from both study groups under ultraviolet light before and after foot washing. The blue-white fluorescent areas indicate the presence of fluorescence from the residual cream, and the bluish-black areas represent the absence of fluorescence. (a) The soles of the participant’s feet are infected with tinea pedis (TP) before foot washing. (b) The soles of the same participant’s feet after foot washing. The fluorescence intensity reduction rate (FIRR) is 34.9%. (c) The soles of the participant’s feet do not show TP infection before foot washing. (d) The soles of the same participant’s feet after foot washing. The FIRR is 88.6%. (e) Areas between the toes of a participant with TP before foot washing. (f) Areas between the toes of the same participant after foot washing. This participant has residual cream. (g) Areas between the toes of a participant without TP infection before foot washing. (h) Areas between the toes of the same participant after foot washing. This participant has no residual cream. The nails are showing autofluorescence.
