Nail bed malignancies are rare entities. Most nail bed malignancies are squamous cell carcinoma (SCC)s. Less than 10% of subungual SCCs occur in the foot. Fifty percent occurred on the hallux and approximately 25% on both the fourth and fifth digits. The correct diagnosis is often delayed because nail bed malignancies are frequently mistaken for benign or infectious processes. SCC on extremities is hard to distinguish from the benign lesion like chronic ulcer, fistula caused by chronic osteomyelitis, and abscess fistula. Attention should especially be paid in diagnosing the subungual lesion because paronychia is a common disease. SCC is the most common carcinoma second to malignant melanoma as a soft tissue malignant tumor in the West, and it involves mainly the head, neck and upper extremities but rarely involves lower extremities, particularly the toes. The authors emphasize the importance of a biopsy for chronic nonhealing lesions by presenting this case.

Background Some diabetic feet heal without complication, but others undergo amputation due to progressive wounds. This study investigates the risk factors for amputation of diabetic feet. Methods A total of 55 patients who visited our institution from 2008 to 2012 were included in the study. The patients with abnormal fasting blood sugar levels, lower leg vascularity, and poor nutrition were excluded from the study group, and the wound states were unified. The patients were categorized into a treatment success group (n=47) and a treatment failure group (n=8), and their hemoglobin A1C (HgA1C), C-reactive protein (CRP), white blood cell count (WBC), and serum creatinine levels were analyzed. Results The initial CRP, WBC, and serum creatinine levels in the treatment failure group were significantly higher than that of the treatment success group, and the initial HgA1C level was significantly higher in the treatment success group. The CRP and WBC levels of both groups changed significantly as time passed, but their serum creatinine levels did not. Conclusions The initial CRP, WBC, and serum creatinine levels were considered to be risk factors for amputation. Among them, the serum creatinine level was found to be the most important predictive risk factor. Because serum creatinine represents the renal function, thorough care is needed for the feet of diabetic patients with renal impairment.
Purpose: Adequate tissue oxygenation is considered as an essential factor for wound healing. In the non-diabetic population, an uncompromised macrocirculation generally leads to adequate tissue oxygenation. On the contrary, the macrocirculation in diabetic patients may not correlate with tissue oxygenation because of structural changes in the capillary basement membrane. Nevertheless, many medical professionals in Korea rely on macrocirculation evaluation when predicting wound healing potential of the diabetic ulcers. The purpose of this study is to compare reliability of two common macrocirculation assessment methods, Doppler probing and CT angiography, on tissue oxygenation in diabetic foot patients. Methods: Doppler and CT angiography scores were given according to the patency of the anterior and posterior tibial arteries. Tissue oxygenation was measured by transcutaneous partial oxygen tension($TcpO_2$). Doppler and CT angiography scores were statistically analyzed against $TcpO_2$ values. Sixty-eight diabetic foot ulcer patients were included in this study. Results: The test was carried out on Doppler score and $TcpO_2$ variables displayed a p-value of 0.0202, and concluded that the two variables were statistically dependent. The test used to determine for linear trends between Doppler scores and $TcpO_2$ variables displayed a p-value of 0.0149, displaying statistical linear trend between the two variables. On the contrary, the tests between CT angiography scores and $TcpO_2$ variables showed p-values of 0.1242 and 0.6590, that means no correlation between CT angiography and $TcpO_2$ scores. Conclusion: Doppler probing is more reliable than CT angiography in predicting tissue oxygenation of diabetic foot ulcers.
Many clinical trials have shown the effectiveness of the platelet releasate or the platelet gel on chronic wounds. However, the patient's own blood had to be aspirated and processed to make the platelet releasate or a platelet gel. The purpose of this study was to assess the effects of platelet concentrates from the blood bank for the treatment of diabetic foot ulcers. To obtain the basic data of the PDGF-BB content in platelet concentrates supplied from the blood bank, enzyme-linked immunosorbent assay quantification was performed. On average, 8.5 pg of the PDGF-BB was released per 1 million platelets. Sixteen patients with diabetic foot ulcers ranging from 1.0 to $18.0cm^2$(mean, $6.1cm^2$) in size were treated. The platelet concentrates was centrifuged and the precipitantte was mixed with 1 ml of fibrinogen. The platelets and fibrinogen mixture was dispersed on to the ulcer lesions. The liquid platelet and fibrinogen mixture was then sealed using 0.3-1.0 ml of thrombin and moisture dressing was performed. The procedure was repeated every one or two weeks until wound closure. Time required for complete healing ranged from 3 to 12 weeks after treatment (mean, 7.3 weeks). Patient satisfaction was also very positive. In this study, the use of platelet concentrates from the blood bank was found to be effective in treating diabetic foot ulcers.
Purpose: The present study aimed to develop guidelines regarding initial choice of antibiotics for diabetic foot ulcers (DFU) by investigating bacterial isolates. Materials and Methods: This study included 223 DFU patients that visited a single tertiary hospital and underwent bacterial culture between January 2016 and February 2020. The study was conducted in two parts: 1) to compare bacterial isolates and wound healing according to comorbidities such as chronic kidney disease (CKD) and peripheral artery disease (PAD), and 2) to compare bacterial isolates according to wound depth using the Wagner classification. Results: Of the 223 patients, 43 had CKD (group A), 56 had PAD (group B), 30 had CKD and PAD (group C), and 94 had none of these comorbidities (group D). The isolation rate for multidrug-resistant gram-negative bacteria (MRGNB) and gram-negative to gram-positive bacteria ratio were highest in group C (p=0.018, p=0.038), and the proportion that achieved wound healing was lowest in group C (p<0.001). In the second part of the study, subjects were classified into 5 grades by wound depth using the Wagner classification; 13 grade I, 62 grade II, 60 grade III, 70 grade IV, and 17 grade V. No significant difference was observed between these grades in terms of isolation rates or gram-negative to gram-positive bacteria ratios. Conclusion: This study suggests antibiotics that cover gram-negative bacteria including MRGNB produces better results in the presence of CKD and PAD and that initial antibiotic choice should be based on the presence of CKD and PAD rather than wound depth.
1. Objectives Besides Diabetes Mellitus, its complications are matter of concerns as well. Its following complications are cardiovascular disease, glomerulopathy, retinopathy, neuropathy and diabetic gangrene. These complications can cause overall damage in major organs. In traditional oriental medicine it has been perceived that gangrene is mainly caused by "hwa(火)" but under sasang constitutional medicine its has been diagnosed as Taeumin superficial-disease(太陰人 表病) and Taeumin Jowiseungchung-tang(調胃升淸湯) was prescribed. As a result, significal improvments was noted and thefore we report the outcome. 2. Methods We have given Taeumin Jowiseungchung-tang(太陰人 調胃升淸湯) to a patient for treating diabetes complications. 3. Results This patient was treated with Sasang Constitional Medicine and acupuncture for about three weeks. After treatment, ulcer and whole body edema were improved considerbly. 4. Conclusions We have dianosed the patient as Taeumin superficial-disease(太陰人 表病) by undergoing several diagnostic method used in sasang constutional medicine. Therefore we have given Taeumin Jowiseungchung-tang(太陰人 調胃升淸湯) to the patient and has obtained satisfactory results in curing several diabetic complications especially ulcer due to diabetes.

This study proposes an alternative approach for the use of chitosan silver-based dressing for the control of foot infection with multidrug-resistant bacteria. Sixty-five bacterial isolates were isolated from 40 diabetic patients. Staphylococcus aureus (37%) and Pseudomonas aeruginosa (18.5%) were the predominant isolates in the ulcer samples. Ten antibiotics were in vitro tested against diabetic foot clinical bacterial isolates. The most resistant S. aureus and P. aeruginosa isolates were then selected for further study. Three chitosan sources were tested individually for chelating silver nanoparticles. Squilla chitosan silver nanoparticles (Sq. Cs-Ag0) showed the maximum activity against the resistant bacteria when mixed with amikacin that showed the maximum synergetic index. This, in turn, resulted in the reduction of the amikacin MIC value by 95%. For evaluation of the effectiveness of the prepared dressing using Artemia salina as the toxicity biomarker, the LC50 was found to be 549.5, 18,000, and 10,000 μg/ml for amikacin, Sq. Cs-Ag0, and dressing matrix, respectively. Loading the formula onto chitosan hydrogel dressing showed promising antibacterial activities, with responsive healing properties for the wounds in normal rats of those diabetic rats (polymicrobial infection). It is quite interesting to note that no emergence of any side effect on either kidney or liver biomedical functions was noticed.

Purpose: Diabetic foot wound (DFW) is known as a major contributor of nontraumatic lower extremity amputation. We aimed to evaluate overall amputation rates and risk factors for amputation in patients with DFW. Materials and Methods: From January 2014 to December 2017, 141 patients with DFW were enrolled. We determined rates and risk factors of major amputation in DFW and in DFW with peripheral arterial occlusive disease (PAOD). In addition, we investigated rates and predictors for amputation in diabetic foot ulcer (DFU). Results: The overall rate of major amputation was 26.2% in patients with DFW. Among 141 DFWs, 76 patients (53.9%) had PAOD and 29 patients (38.2%) of 76 DFWs with PAOD underwent major amputation. Wound state according to Wagner classification, congestive heart failure, leukocytosis, dementia, and PAOD were the significant risk factors for major amputation. In DFW with PAOD, Wagner classification grades and leukocytosis were the predictors for major amputation. In addition, amputation was performed for 28 patients (38.4%) while major amputation was performed for 5 patients (6.8%) of 73 DFUs. Only the presence of osteomyelitis (OM) showed significant difference for amputation in DFU. Conclusion: This study represented that approximately a quarter of DFWs underwent major amputation. Moreover, over half of DFW patients had PAOD and about 38.2% of them underwent major amputation. Wound state and PAOD was major predictors for major amputation in DFW. Systemic factors, such as CHF, leukocytosis, and dementia were identified as risk factors for major amputation. In terms of DFU, 38.4% underwent amputation and the presence of OM was a determinant for amputation.
Purpose: This study analyzed the clinical and radiological results of Reudi-Allgower type II and III open tibia pilon fracture patients who underwent plate fixation after the recovery of a soft tissue injury after external fixation. Materials and Methods: From 2010 to 2015, this study analyzed 14 patients who were treated for open tibial pilon fractures and could be followed up at least one year. The mean age was 49 years and the average follow-up period was 19 months. An emergency operation was performed for external fixation and open wounds, and secondary surgery was performed for definitive fixation using a plate. The radiological and clinical evaluations were analyzed retrospectively. Complications, such as post-traumatic osteoarthritis and wound infections were also analyzed. Results: The mean duration between two-staged surgery was 21 days and the mean bone union time was 9.2 months. Three cases of delayed union and one case of nonunion were reported. The malunion did not occur in all cases. The average American Orthopaedic Foot and Ankle Society (AOFAS) score was 68 points. A limitation of the ankle motion occurred in all cases. In four cases, wound infections due to initial open wounds occurred; one patient underwent a below the knee amputation due to chronic osteomyelitis. Post-traumatic arthritis occurred in 10 cases. Conclusion: Severe comminuted tibial plateau open fractures of Reudi-Allgower type II and III, which are high-energy injuries that result in extensive soft tissue damage, have a higher incidence of complications, such as ulcer problems and osteomyelitis, than closed tibia plateau fractures. Post-traumatic arthritis is the most common complication of tibia plateau open fractures, and staged surgery is recommended because of the relatively satisfactory clinical results.
Purpose: Anatomically, the foot is provided with insufficient blood supply and is relatively vulnerable to venous congestion compared to other parts of the body. Soft tissue defects are more difficult to manage and palliative treatments can cause hyperkeratosis or ulcer formation, which subsequently requires repeated surgeries. For weight bearing area such as the heel, not only is it important to provide wound coverage but also to restore the protective senses. In these cases, application of flaps for hind foot reconstruction is widely recognized as an effective treatment. In this study, we report the cases of soft tissue reconstruction for which various types of flaps were used to produce good results in both functional and cosmetic aspects. Methods: Data from 37 cases of hind foot operation utilizing flaps performed between from June 2000 to June 2008 were analyzed. Results: Burn related factors were the most common cause of defects, accounting for 19 cases. In addition, chronic ulceration was responsible for 8 cases and so forth. Types of flaps used for the operations, listed in descending order are radial forearm free flap (18), medial plantar island flap (6), rotation flap (5), sural island flap (3), anterolateral thigh free flap (2), lattisimus dorsi muscular flap (2), and contra lateral medial plantar free flap (1). 37 cases were successful, but 8 cases required skin graft due to partial necrosis in small areas. Conclusion : Hind foot reconstruction surgeries that utilize flaps are advantageous in protecting the internal structure, restoring functions, and achieving proper contour aesthetically. Generally, medial plantar skin is preferred because of the anatomical characteristics of the foot (e.g. fibrous septa, soft tissue for cushion). However alternative methods must be applied for defects larger than medial plantar skin and cases in which injuries exist in the flap donor / recipient site (scars in the vicinity of the wound, combined vascular injury). We used various types of flaps including radial forearm neurosensory free flap in order to reconstruct hind foot defects, and report good results in both functional and cosmetic aspects.
