Severe burn injuries often result in significant long-term physical complications with scarring and contractures, but cancers associated with chronic burn scars are relatively rare. We report a case of a 58-year-old man with skin cancer arising from a healed burn scar. He initially suffered from an extensive fire burn on both lower limbs as a child. The burn scars extended from his upper thighs to his toes bilaterally and caused severe contractures which immobilized the ankles in plantar flexion. Two years ago, he noticed a small ulcerated lesion on the right heel and self-treated it with topical ointments. However, the ulcer increased in size and became malodorous. He presented to a clinic with a large, ulcerated, tumorous lesion, and histology proved it to be squamous cell carcinoma. He subsequently underwent a right below-the-knee amputation, and the previous scars presented on the stump. Thus the patient received a total surface bearing prosthesis with an Icelandic roll-on silicone socket system, which is ideal for patients with extensive scarring at the stump because it may reduce prosthesis-induced stump injuries by evenly distributing the patient's weight in the socket. After he left the hospital, he walked so far with the prosthesis every day that small ulcers often developed at the right popliteal fossa. However, he did not take care to treat these lesions properly, so we had to educate him on how to treat them. Patients such as these will often require education for self-management, family involvement and regular follow-up to monitor scar ulceration and watch out for any malignant transformation.

This cross-sectional study examines the association between coping with past ankle sprain, and current physical activity levels and sedentary times. It included a total of 1,464 male soccer players, who participated in the 6th Senior Soccer Festival in Shizuoka in 2017. A self-administered questionnaire was conducted on the day of the festival and 567 subjects responded (38.7% response rate). Participants answered questions regarding the coping with past ankle sprain, such as whether they had first aid treatment (yes/no), the type of initial treatment facilities (6 categories), and their most frequented facilities (5 categories). Additionally, the International Physical Activity Questionnaire Short Form was used to obtain information on current physical activity level and sedentary time. We compared the mean values of physical activity levels and sedentary times with the first aid treatment, initial treatment facilities and most frequented facilities answers, respectively. The mean age was 64.7 years. Physical activity level was associated with first aid treatment (yes: 3860.3 Metabolic equivalents (METs)/min/week; no: 3082.0 METs/min/week) (p=0.033). Sedentary time was also associated with first aid treatment (yes: 265.4 min/day; no: 321.3 min/day) (p=0.014). Initial treatment facilities and most frequented facilities were not associated with physical activity levels or sedentary times. Our study showed that those who had received first aid treatment had high physical activity levels and low sedentary time.
