This study aimed to identify the learning requirements of nurses practicing diabetic foot care. Semi-constructive interviews were conducted with 15 nurses who had completed appropriate training in the teaching of diabetic foot lesion care and who were involved in the foot care of patients with diabetes at a medical institution. The obtained data were qualitatively and descriptively analyzed. Five categories of learning needs were generated: biomechanics-based foot care, assessment skills in foot care practice, techniques to facilitate multidisciplinary collaboration, direct foot care techniques performed on patients, and developing new educational tools to deepen learning. Our findings suggest learning needs that could not be fulfilled by conventional training programs alone. Thus, participants may feel a gap between the skills and abilities they acquired during training and those required in the field. Therefore, to address the complex and diverse needs of patients with diabetic foot lesions in the future, establishing an educational system that incorporates the perspectives of physical therapists, prosthetists, and other professionals, and also utilizes audiovisual aids and other educational materials is necessary.

　Lower extremity artery disease (LEAD) has been increasing in recent years. LEAD manifests as various symptoms depending on severity and multidisciplinary treatment is required. Successful revascularization is an important part of treatment for moderate and severe cases.
 Various methods are conventionally used to evaluate revascularization, but evaluating microvascular blood flow intraoperatively is difficult. Therefore, we attempted to use a laser Doppler flow meter to evaluate revascularization in a LEAD patient presenting with intermittent claudication. An increase in blood flow was observed intraoperatively, suggesting the usefulness of laser Doppler flow meter for evaluating microvascular blood flow during revascularization.

　This report describes progress in the use of OASIS^® extracellular matrix for chromic refractory leg ulcers. The subjects were four patients visiting our outpatient lower limb wound care clinic, who had intractable leg ulcers with different causes. The results showed good progress in two cases, but no improvement in the other two. In the autologous cases, the selection of appropriate secondary dressings and their appropriate replacement and debridement were important to ensure the effectiveness of OASIS^®. In addition, the control of exudate and infection influenced wound healing. The synergistic effects of OASIS^® and compression therapy promoted wound healing.
