RESUMO

BACKGROUND: Diabetic foot ulcers (DFUs) constitute a complication that occurs in 19% to 34% of patients with diabetes mellitus (DM). The aim of this study is to describe median days to healing, average velocity of wound closure, and percentage of wound surface closed at 3, 6, and 12 weeks through the use of homogenized and lyophilized amniotic membrane (hAMpe) dressings for the treatment of DFUs in ambulatory patients. METHODS: An observational, descriptive, longitudinal study was performed. Patients presenting with granulation-based DFU, after proper debridement, were included from August 19, 2021, until July 14, 2023. hAMpe dressings placed every 3 days were used for the treatment of these ulcers. RESULTS: Sixteen patients were included with a mean age of 52.38 (8.07) years. The analyzed lesions were postsurgical ulcers in 15 of the 16 included patients. Median ulcer size was 19.5 cm2 (6.12-36). The median ABI was 1.10 (1-1.14). The median days to healing was 96 (71-170). The median percentage closure of the wound at 3 weeks was 41% (28.9%-55.3%), at 6 weeks it was 68.2% (48.6%-74.2%), and at 12 weeks it was 100% (81%-100%). The average velocity closure was 1.04% per day (95% CI 0.71%-1.31%). It was higher during the closure of the first 50% of the ulcer, 2.12% per day (95% CI 0.16%-4.09%), and decreased from 50% to 25% of the ulcer size to 0.67% per day (95% CI 0.23%-1.10%) and from 25% to closure to 0.47% per day (95% CI 0.14%-0.80%), P < .001. CONCLUSION: These results are difficult to compare to other studies given the higher surface area of the ulcers included in our sample. The development of hAMpe dressings enables patients to apply them without requiring assistance from health care teams and was not associated with any recognized complications.

RESUMO

Diabetic foot (DF) is one of the most devastating complications of diabetes mellitus (DM). Infrared thermography has been studied for its potential in early diagnosis and preventive measures against DF ulcers, although its role in the management and prevention of DF complications remains uncertain. The objective of this study was to determine the average temperatures of different points of the plantar foot using infrared thermography in patients with DM and history of DF (DFa group, at the highest risk of developing foot ulcers) and compare them to people without DM (NoDM group). One hundred and twenty-three feet were included, 63 of them belonged to DFa Group and the other 60 to NoDM Group. The average temperature in the NoDM Group was 27.4 (26.3-28.5) versus 28.6 (26.8-30.3) in the DFa Group (p = .002). There were differences between both groups in temperatures at the metatarsal heads and heels, but not in the arch. Average foot temperatures did not relate to sex, ankle-brachial index, and age, and had a mild correlation with daily temperature (Spearman 0.51, p < .001). Data provided in our study could be useful in establishing a parameter of normal temperatures for high-risk patients. This could serve as a foundational framework for future research and provide reference values, not only for preventative purposes, as commonly addressed in most studies, but also to assess the applicability of thermography in clinical scenarios particularly when one foot cannot serve as a reference, suspected osteomyelitis of the remaining bone, or instances of increased temperature in specific areas which may necessitate adjustments to the insoles in secondary prevention.

RESUMO

Resumen Introducción : El pie diabético (PD) representa una complicación con elevada morbimortalidad. En Ar gentina, carecemos de datos acerca de tasas de am putación y mortalidad relacionada a esta enfermedad. El objetivo de este estudio fue describir las caracte rísticas de todos los pacientes adultos con diabetes que consultaron por PD durante 3 meses y evaluar su evolución a 6 meses. Métodos : Se realizó un estudio descriptivo longitudi nal con seguimiento a 6 meses. Resultados : Se estudiaron 312 pacientes de 15 cen tros de Argentina. Durante el estudio, el porcentaje de amputación mayor total fue de 8.3% (IC95; 5.5-11.9) (n = 26) y el de amputación menor de 29.17% (IC95%; 24.2-34.6) (n = 91). En el seguimiento a 6 meses, el por centaje de muerte fue de 4.49% (IC95%; 2.5-7.4) (n = 14), el 24.3% (IC95%; 19.6-29.5) presentaba la herida aún abierta (n = 76), el 58.0% (IC95%; 52.3-63.5) (n = 181) cicatrizó y 7.37% se perdió del seguimiento (n = 23). De los pacientes que sufrieron una amputación mayor antes de los 6 meses (n = 24), 5 fallecieron (20.8%) en contraste con el 3% de quienes no se amputaron (p = 0.001). La amputación mayor se relacionó con la edad, el índice tobillo brazo (ITB), la escala de San Elián, la de SINBAD y la clasificación de WIfI, la isquemia y con algunos aspectos de la herida. Discusión : El conocimiento de datos locales permitirá mejorar la toma de decisiones en cuanto a políticas de salud relacionadas a la prevención y el tratamiento de los pacientes con PD.

Abstract Introduction : The diabetic foot (DF) is a complica tion with high rate of morbi-mortality. There are no data about amputation rates and mortality in Argentina related to this disease. The aim of this study was to de scribe clinical features of adult patients with diabetes that consulted for a foot ulcer in a 3 months' period and to evaluate outcomes six months later. Methods : This is a multicenter longitudinal study with six months follow up. Results : Three hundred and twelve patients from 15 health centers in Argentina were analyzed. During the follow up, the rate of major amputation was 8.3% (IC95; 5.5-11.9) (n = 26) and minor amputation 29.17% (IC95%; 24.2-34.6) (n = 91). After six months, the mortality rate was 4.49% (IC95%; 2.5-7.4) (n = 14), and 24.3% (IC95%; 19.6-29.5) remained with open wounds (n = 76) while 58.0% (IC95%; 52.3-66.5) (n = 181) healed and 7.37% be came lost to follow up (n = 23). From those who required a major amputation during the study (n = 24), 5 patients died (20.8%) and in patients without amputation, 3% died (p = 0.001). Major amputation was related to age, ankle brachial index (ABI), Saint Elian score (SEWSS), SINBAD, WIfI classification, ischemia and some aspects of the wound. Discussion : Knowledge about local data will enable better decisions on health policies related to prevention and treatment of diabetic foot patients.

RESUMO

Introducción: las clasificaciones de pie diabético (PD) son una herramienta que tienen el objetivo de mejorar la comunicación entre los profesionales, la referencia y contrarreferencia; proporcionar un pronóstico; ayudar en la valoración de las lesiones, y contribuir con fines estadísticos. Objetivos: describir las características de los pacientes que se presentaron al consultorio o a la guardia con un PD durante un período de 3 meses, determinar el riesgo según cinco clasificaciones (Texas, IDSA, San Elián, WIfI y SINBAD) y evaluar su evolución a 6 meses en relación con el grado de gravedad determinada por cada clasificación. Materiales y métodos: se analizaron 312 pacientes de 15 instituciones en Argentina. Para el análisis se utilizó la calculadora de clasificaciones de pie diabético/score de riesgo del Comité de Pie Diabético de la Sociedad Argentina de Diabetes. Resultados: el 43% de los pacientes (n=133) requirió internación al momento de la primera consulta y el 61% (n=189) había consultado previamente. El porcentaje de amputación mayor total fue de 8,33% (IC 95%; 5,5-11,9) (n=26) y el de amputación menor de 29,17% (IC 95%; 24,2-34,6) (n=91). A los 6 meses, el porcentaje de muerte fue de 4,49% (IC 95%; 2,5-7,4) (n=14), el 24,3% (IC 95%;19,6-29,5) presentaba la herida aún abierta (n=76), el 58,0% (IC 95%; 52,3-66,5) (n=181) cicatrizó y el 7,37% se perdió del seguimiento (n=23). Las clasificaciones de San Elián y WIfI se relacionaron con amputación mayor, cicatrización y muerte. En relación a la clasificación de Texas, el 49% de los pacientes presentó herida penetrante a hueso o articulación (Texas 3), con o sin infección. El 65,3% de las amputaciones mayores y el 78,6% de las muertes se produjeron en pacientes con isquemia. El punto de corte de San Elián para amputación mayor fue 20. Conclusiones: conocer los datos locales permite organizar los recursos para mejorar la atención de los pacientes.

Introduction: the classifications of diabetic foot (DF) are a tool that aims to improve communication between professionals, referral and counter-referral, provide a prognosis, help in the assessment of lesions, and contribute to statistical purposes. Objectives: to describe the characteristics of patients who presented to the clinic or emergency department with DF over a period of 3 months, determine the risk according to 5 classifications (Texas, IDSA, SEWSS, WIfI, and SINBAD), and evaluate their evolution at 6 months in relation to the severity degree determined by each classification. Materials and methods: 312 patients from 15 institutions in Argentina were analyzed. The Diabetic Foot Classification Calculator/Risk Score from the Diabetic Foot Committee of the Argentina Argentina Diabetes Society was used for the analysis. Results: 43% of patients (n=133) required hospitalization at the time of the first consultation and 61% (n=189) had previously consulted. The total major amputation percentage was 8.33% (95%CI; 5.5-11.9) (n=26), and the minor amputation percentage was 29.17% (95% CI; 24.2-34.6) (n=91). At 6 months, the death rate was 4.49% (95% CI; 2.5-7.4) (n=14), 24.3% (95% CI; 19.629.5) had an open wound (n=76), 58.0% (95% CI; 52.3-66.5) (n=181) had healed, and 7.37% were lost to follow-up (n=23). The SEWSS and WIfI classifications were related to major amputation, healing, and death. Regarding the Texas classification, 49% of patients had a penetrating wound to bone or joint (Texas 3), with or without infection. 65.3% of major amputations and 78.6% of deaths occurred in patients with ischemia. The SEWSS cut-off point for major amputation was 20. Conclusions: knowing local data allows organizing resources to improve patient care.

RESUMO

Diabetic foot osteomyelitis (OM) requires a longer duration of therapy, a greater need for surgery and implies a higher rate of recidivism, a higher amputation risk, and lower treatment success. But do all bone infections behave the same way, require the same treatment, or imply the same prognosis? Actually, in clinical practice we can verify there are different clinical presentations of OM. The first one is that associated with the infected diabetic foot attack. It requires urgent surgery and debridement since "time is tissue." Clinical features and radiographs are enough for the diagnosis, and treatment should not be delayed. The second one is related to a sausage toe. It affects phalanges and it can be treated with a 6- or 8-week antibiotic course with a high rate of success. Clinical features and radiographs are sufficient for the diagnosis in this case. The third presentation is OM superimposed to Charcot's neuroarthropathy, which mainly comprises midfoot or hindfoot. It starts with a plantar ulcer in a foot that has developed a deformity. The treatment is based on an accurate diagnosis that often includes magnetic resonance, and requires a complex surgery to preserve the midfoot and to avoid recurrent ulcers or foot instability. The final presentation is that of an OM without large soft tissue compromise secondary to a chronic ulcer or a previous unsuccessful surgery secondary to minor amputation or debridement. There is often a small ulcer with a positive probe to bone test over a bony prominence. Diagnosis is made by clinical features, radiographs, and laboratory tests. Treatment includes antibiotic therapy guided by surgical or transcutaneous biopsy, but this presentation often requires surgery. Different presentations of OM mentioned above need to be recognized because the diagnosis, type of culture, antibiotic treatment, surgical treatment, and prognosis are different upon the presentation.

RESUMO

INTRODUCTION: Different COVID-19 vaccines were developed in a short time after the beginning of pandemics, reducing mortality, especially in high risk population. This was demonstrated in several studies, mostly retrospective or based in mathematical models. The objective was to compare mortality in inpatients with COVID-19 related to vaccination. METHODS: Longitudinal, prospective, comparative, observational study. Inpatients with COVID-19 diagnosis were included between 17/12/2021 and 23/02/22, in Hospital Nacional Prof. A Posadas and Hospital Interzonal General de Agudos Eva Perón. RESULTS: Inpatients (245) were analyzed, finding an overall mortality of 25.3%, 16.8% in fully vaccinated patients (two or more doses with less than 150 days since the last dose until the COVID-19 test) and 31.9% in those with incomplete vaccination (unvaccinated, one dose or two or more doses with more than 150 days since the last dose) (p = 0.007), OR 2.31 (IC95; 1.25-4.28) for incomplete vaccination. Mortality was 32.2% in patients who developed pneumonia, 22.2% for fully vaccinated and 38% for incompletely vaccinated (p = 0.048), OR 2.15(IC95; 1.01-4.58). Mortality was associated with older age (70 vs. 59 years; p < 0.001), female sex (54.8% vs. 37.7%; p < 0.02) and oncologic disease (27.4 vs. 14.8%; p = 0.02). PESI score was higher in incompletely vaccinated (102.5 vs. 93, p = 0.05) and SOFA score was lower (2 vs. 3, p = 0.01). The necessary number to treat (NNT) to prevent one death was 7 patients for the overall sample (IC95;4-22) and 6 (IC95;3-106) for pneumonia. DISCUSSION: This study constitutes a starting point for developing other investigations and raising awareness of medical community and people about the beneficial effects of vaccination.

Introducción: Luego del inicio de la pandemia por COVID-19, se desarrollaron diferentes vacunas, disminuyendo la mortalidad según estudios retrospectivos o con modelos de cálculo. El objetivo fue comparar la mortalidad de pacientes internados con diagnóstico de COVID-19 según su vacunación. Métodos: Estudio comparativo observacional longitudinal. Se incluyeron pacientes internados con COVID-19 del 17/12/21 al 23/02/2022 en el Hospital Nacional Prof. A Posadas y en el Hospital Interzonal General de Agudos Eva Perón. Resultados: Se analizaron 245 pacientes hallando una mortalidad total del 25.3%, 16.8% en aquellos con vacunación completa (2 dosis o más y menos de 150 días desde la última) y 31.9% con vacunación incompleta (no vacunados, 1 o 2 dosis y más de 150 días desde la última) (p = 0.007), OR 2.31(IC95; 1.25-4.28). En aquellos con neumonía, la mortalidad fue del 32.2%, 22.2% con vacunación completa y 38% con vacunación incompleta (p = 0.048), OR 2.15(IC95; 1.01-4.58. La mortalidad se asoció a mayor edad (70 vs. 59 años; p < 0.001), sexo femenino (54.8% vs. 37.7%; p < 0.02) y enfermedad oncológica (27.4 vs. 14.8%; p = 0.02). El PESI score fue mayor en aquellos con vacunación incompleta (102.5 vs. 93, p = 0.05) y el SOFA score fue menor (2 vs. 3, p = 0.01). El número necesario a tratar (NNT) para evitar una muerte fue de 7 pacientes para el total de la muestra (IC95; 4-22) y 6 (IC95;3-106) para aquellos con neumonía. Discusión: Este trabajo constituye un punto de partida de nuevas investigaciones, contribuyendo a la concientización acerca de los efectos beneficiosos de la vacunación en profesionales y pacientes.
