“…Most commonly occurring foot patterns among diabetic patients are shown below in figures 2 to 5 [17]. The complete flow and occlusions in the Lateral Plantar Artery (LPA), Lateral Calcaneal Artery (LCA), Medial Plantar Artery (MPA), and Medial Calcaneal Artery (MCA) for different types of diabetic foot are represented here.…”

Thermographic images are widely used in diagnosing Diabetic foot (DF) infection and ulceration that are associated with neurological abnormalities. Thermographic images of various diabetic foot ulcerated conditions are collected from 60 patients. There are twenty different types of conceptual foot patterns occurring in diabetic patients, out of which most predominantly observed are type 3A, type 1D, type 3D, type 4D. This work proposes on developing an automatic algorithm to match these diabetic thermographic images of ulcerated foot with conceptual template rather than manually comparing it with the thermogram datasheet. A conceptual template is created using the thermogram datasheet for each of these twenty patterns by edge mapping and curvelet technique. About 60 thermographic images of diabetic foot that have the most predominant patterns are taken for study. These images are pre-processed and segmented for ulcerated region of interest. A pattern for these thermographic images is generated using edge mapping technique and Hough transform. The broken edges are joined by curvelet technique to form a pattern. Each of these patterns is compared with the twenty conceptual templates by template matching technique and an overall efficiency of about 95.27 percent is achieved. This automated algorithm helps the physicians in finding the accurate type of diabetic foot and it is possible to detect the pre-signs of ulcerations in foot.

“…33 Thermography and ultrasound techniques have been explored to assess differences in callus tissue. 34 Optical coherence tomography (OCT) and near-infrared (NIR) imaging were used to measure changes in optical depth and contrast (of diffuse reflectance) in callus tissue following dissolved keratin treatment. 35 In this study, NIR imaging is used to assess tissue oxygenation (TO) changes following SD in pre-ulcerative cases.…”

Background: Callus formation in the diabetic foot increases the risk of ulcer onset. It is standard procedure to remove these dead tissue layers to reduce rising pressures. In a surgical procedure known as scalpel debridement, or chiropody the callus tissue is removed up to the epidermal layer. Factors may influence the outcome of this surgical process such as clinician inexperience. In an effort to standardize the debridement process, tissue oxygenation (TO) measurements are obtained before and after to study the effect of debridement on callus tissue. Methods: Fifteen debridement cases were analyzed using near infrared (NIR) imaging to study changes in TO. The NIR-based device used in this study estimates effective changes in TO in terms of oxy-, deoxy-, total hemoglobin, and oxygen saturation. Weber contrasts between callus tissue and the surrounding normal tissue were compared following debridement for all TO parameters. In a secondary analysis, callus tissue was segmented into quadrants and a percent of significance (in terms of total TO change) was calculated using a t-test. Results: Results show majority of cases displayed greater than 80% as the significant change in TO following debridement, except in cases with the presence of blood clot (a common precursor for ulceration). In cases where incomplete debridement was suspected, a significant change in TO was still observed. Conclusions: With extensive systematic studies in the future, NIR imaging technique to measure changes in TO may be implemented as a low-cost hand-held imaging device useful for objectively assessing the effectiveness of the scalpel debridement process.

“…El pie diabético (PD) es definido como la infección, ulceración y/o destrucción de tejidos profundos asociado a alteraciones neurológicas y varios grados de enfermedad vascular periférica de miembros inferiores de pacientes con DM. Esta enfermedad relacionada a miembros pélvicos está dentro de las más serias y costosas complicaciones dentro del espectro de DM, que al estar presentes pueden resultar en la formación de ulceras y la subsecuente amputación de la extremidad inferior afectada (2).…”

Factores cardiovasculares asociados a Pie Diabético Introducción: El pie diabético una de las complicaciones más frecuentes de la Diabetes mellitus con impacto funcional, económico y elevada morbimortalidad, pudiendo ser evitado hasta en 75% de casos con modificación sus factores de riesgo; en la literatura mundial la frecuencia de los factores de riesgo cardiovascular en el Pie Diabético son referidos en pocas veces de manera individual, por lo que su correcta identificación daría una base más sistemática para su abordaje. Objetivo: Identificar los Factores cardiovasculares en pacientes con Diabetes mellitus que están asociados a pie diabético. Material y métodos: El estudio es observacional, analítico con diseño trasversal, en pacientes adultos en área de urgencias con diagnóstico de Diabetes mellitus. Se estudiaron las variables: presencia o ausencia de pie diabético, edad, género, hipertensión, sobrepeso, tabaquismo, Dislipidemia. Mediante R Studio 1.0.153, se determinó normalidad, se realizaron correlaciones y comparaciones entre variables. Análisis estadístico: Se obtuvieron 201 pacientes, media de edad: 59.4±15.3 años, 48.76% de género masculino y 51.24% femenino; prevalencia de pie Diabético de 31.34% (63 pacientes). Se analizó cada variable, siendo no estadísticamente significativas: edad (p=0.2172), Sexo (p= 0.8796), sobrepeso u Obesidad (p= 0.1423), Tabaquismo (p= 0.4993) y dislipidemia (p=0.8699). Existió una asociación estadísticamente significativa para hipertensión mediante Prueba Exacta de Fisher (p: 0.001156), con intervalo de confianza de 95% (1.556-9.603) y Odds Ratio de 3.6456. Conclusiones: De las variables señaladas como factores de riesgo cardiovascular solo la hipertensión arterial sistémica presento correlación estadísticamente significativa con el pie diabético.
