The author experienced a case of autologous platelet-rich plasma (PRP) affecting the recovery of a chronic neuropathic diabetic foot ulcer combined with infection. A 65-year-aged male with uncontrolled diabetes presented with a Wagner grade 2 diabetic foot ulcer on his left forefoot of more than 2 weeks duration. Osteomyelitis, gangrene, and ischemia requiring acute intervention were absent. Although infection was controlled to a moderate degree, wound healing was unsatisfactory following surgical debridement and simple dressing. Therefore, intralesional autologous PRP injection was performed 5 times as an adjuvant regeneration therapy, and the recalcitrant ulcer healed in 3 months. Intralesional PRP injections are worthwhile as they promote wound regeneration, are evidence-based, safe, and can be easily performed in ambulatory care facilities.

Purpose: This study was conducted to evaluate the effects of foot care education program using foot-reflexo-massage in diabetic patients. Method: A convenience sample of non-equivalent control group time series design was used. It provided foot care education to diabetic patients through small book for both group. For the experimental group, foot-reflexo-massage was taught by a researcher and research assistants. Analysis was done by Repeated Measured ANOVA. Result: There was significant increase in foot care knowledge, self care behavior, between the experimental group and the control group over three different times. There was significant in skin temperature and pulse of foot over three different times and interaction by groups or over time, but there was no significant difference between groups. There was no significant difference in blood flow volume and capillary filling time over three different times, between groups, but there was interaction by groups or over time. But there was significant difference in discrimination in change of dosalis pedis artery blood flow. Conclusion: Findings indicate that this study may contribute to develop nursing intervention for foot care of diabetic patients.

Recently, the International Working Group on the Diabetic Foot and the Infectious Diseases Society of America divided diabetic foot disease into diabetic foot infection (DFI) and diabetic foot osteomyelitis (DFO). DFI is usually diagnosed clinically, while numerous methods exist to diagnose DFO. In this narrative review, the authors aim to summarize the updated data on the diagnosis of DFO. An extensive literature search using "diabetic foot [MeSH]" and "osteomyelitis [MeSH]" or "diagnosis" was performed using PubMed and Google Scholar in July 2023. The possibility of DFO is based on inflammatory clinical signs, including the probe-to-bone (PTB) test. Elevated inflammatory biochemical markers, especially erythrocyte sedimentation rate, are beneficial. Distinguishing abnormal findings of plain radiographs is also a first-line approach. Moreover, sophisticated modalities, including magnetic resonance imaging and nuclear medicine imaging, are helpful if doubt remains after a first-line diagnosis. Transcutaneous bone biopsy, which does not pass through the wound, is necessary to avoid contaminating the sample. This review focuses on the current diagnostic techniques for DFOs with an emphasis on the updates. To obtain the correct therapeutic results, selecting a proper option is necessary. Based on these numerous diagnosis modalities and indications, the proper choice of diagnostic tool can have favorable treatment outcomes.

Purpose: The purpose of this study was to examine the effects of diabetic foot care education for the older adults with low health literacy. Methods: A quasi-experimental design with a non-equivalent control group pretest-posttest was used. The participants who were diagnosed with diabetes, were adults over 65 years old at the welfare center of Y and B city. They were divided into the experimental group (n=32) and the control group (n=31). Inclusion criteria were a score of 5 or under on the Short form of Korean Functional Health Literacy Test and 24 or more on the Korean version of Mini-Mental State Examination. Foot care education was conducted in a small group for 40 minutes, once a week, for three weeks. The education materials are composed of an easy term, picture and photographs to understand easily. Results: The scores of diabetic foot care knowledge (t=4.57, p<.001), foot care self-efficacy (t=6.07, p<.001), and foot self-care behavior (t=4.18, p<.001) were significantly increased in the experimental group compared to the control group. Foot health status was not significantly improved. Conclusion: The findings indicate that this education program can be used as a nursing intervention improving foot care knowledge, foot care self-efficacy, and foot self-care behavior in order to prevent the diabetic foot problems of elderly diabetic persons with low health literacy.

In this study, we analyzed the plantar shear stress and normal pressure in lateral heel diabetic foot patients during walking by using in-shoe local shear stress and plantar pressure measurement systems. The shear force transducer based on the magnetic-resistive principle, was a rigid 3-layer circular disc. Shear transducers were mounted on the locations of four metatarsal heads and heel in the insole. Twelve normal subjects and three diabetic foot patients with diabetic neuropathy in the lateral heel participated in this study. The center of pressure in lateral heel diabetic foot patients moved more medially and directed toward the first, medial to the second metatarsal heads, and the hallux during late stance, making pressure at the medial heel and the second metatarsal head significantly larger than in the normal. Shear stress at the heel changed significantly in early stance and the magnitude of shear stresses in each metatarsal head also changed. Further studies would be very helpful to design foot orthoses in patients with diabetic neuropathy or other diseases.

Purpose: This study aimed to provide basic data for the development of an education program on diabetic foot prevention care for care helpers in long term care facilities. Additionally, it sought to determine care helpers' knowledge and practice regarding diabetic foot prevention care, and to identify the correlation between such knowledge and practice. Methods: This cross-sectional study employed a structured questionnaire. Participants consisted of 90 care helpers who were working in three long term care facilities in Jeju city. Data collection was conducted from September to November 2016. Results: The mean knowledge and practice scores were 8.77±1.28 (range 0~10) and 28.17±2.44 (range 10~30), respectively. Practice regarding diabetic foot prevention care was significantly different by care helpers' gender (t=-2.28, p=.024), period of career in the long term care facility (F=3.29, p=.025), and received education on diabetic foot prevention care (t=3.08, p=.005). A positive correlation was observed between knowledge and practice (r=.35, p<.001). Conclusion: To improve the practice of diabetic foot prevention care, specialized education programs that consider gender and period of career in the long term care facility as well as the improvement of the level of knowledge of care helpers on diabetic foot prevention care are needed.

Purpose: To evaluate the results of anterolateral thigh perforator free flap for reconstruction of foot and ankle in old diabetic patients. Materials and Methods: Fifteen diabetic foot ulcer patients over the age of 55 were operated with anterolateral thigh perforator free flap. Hematological, hemodynamic, diabetic, bacteriologic and radiologic tests were checked with examination of blood vessel state in both the donor site and the recipient site. After surgery, serial check-up was performed at 6 week, 6 month, and 1 year postoperatively on the survival of transplantation tissue, condition of foot, and condition of walking. Results: There are one case of transplantation failure and four cases of partial tissue-necrosis. Delayed wound-healing was observed both recipient and donor tissue sites. At the final follow up, three cases of small ulcer were found at junction of flap and recipient tissue in plantar area. Fourteen out of fifteen patients could walk without any brace or walking aids. Conclusion: Reconstruction of foot and ankle region in old diabetic patients with the anterolateral thigh perforator free flap is a useful method which can prevent the amputation of foot and ankle.

Purpose: Microcirculation of diabetic patients is commonly comporomised, regardless of the condition of the macrocirculation. Therefore, direct tissue oxygenation measurement is recommended in determining tissue viability and predicting wound healing potential. This study was designed to determine cut-off value of the tissue oxygenation in predicting wound healing in diabetic foot patients. Methods: This study included 41 feet of 41 diabetic foot patients who were treated in the Diabetic Wound Center of author's institution between January and June, 2009. Main inclusion criteria were type 1 or 2 diabetes and a foot ulcer (duration > 3 weeks) and ulcer area (from 1 $cm^2$ to 4 $cm^2$). Measurements of the area of diabetic foot ulcer were carried out before treatment. Transcutaneous oxygen pressure ($TcpO_2$) was measured at adjacent site of ulcer. The healing wound was defined as complete wound closure within 12 weeks. Results: Average diabetic foot ulcer areas with healing and nonhealing wounds were $2.67{\pm}0.76$ and $2.59{\pm}0.75\;cm^2$, respectively. There was no significant difference in the wound area between the groups. Average foot $TcpO_2$ in healing and nonhealing wounds were $68.56{\pm}23.07$ and $30.98{\pm}16.66$ mmHg, respectively ($p$ <0.01). The rate of healing wound increased as $TcpO_2$ increased. In particular, $TcpO_2$ lower than 40 mmHg and higher than 40 mmHg showed the most significant difference (wound healing rates of 25% and 71%, respectively). Conclusion: Based on the results of the study, the minimal $TcpO_2$ value thought to be required for adequate wound healing in diabetic wounds (cut-off value) is 40 mmHg.

Of 16 million diabetic patients in the USA, 2.4 millions have experienced diabetic foot ulcer and 67,000 have amputations every year. For treatment of diabetic foot ulcer, Americans spend more than $1 billion each year, including $36,000 per patient for complete treatment and $60,000 for each amputation. Neuropathy and ischemia, two common complications of diabetes mellitus, are the primary underlying risk factors for development of diabetic foot ulcers. Ischemic ulcers develop as a result of low perfusion pressure in the foot with inadequate blood supply, whereas neuropathic ulcers develop from loss of protective sensation. In addition, diabetes also increases the risk of infection by impairing the body's ability to eliminate bacteria. From these circumstances, results are chronic wounds with impaired healing ability.
