ABSTRACT
Resumo As úlceras de membros inferiores, secundárias à doença venosa crônica (DVC), constituem um problema significativo de saúde pública no Brasil e representam cerca de 70% do total dessas úlceras. Apesar dos recentes avanços tecnológicos e das diversas opções terapêuticas utilizadas para essas lesões crônicas, existem diversos fatores que podem estar implicados na resistência ao tratamento. A calcificação distrófica cutânea (CDC) é uma condição rara e frequentemente subdiagnosticada, que, quando associada à DVC, pode estar associada à refratariedade no processo cicatricial. Neste artigo, relatamos um caso de CDC em paciente portador de DVC e discutimos a sua etiologia, fisiopatologia e possíveis opções de tratamento.
Abstract Lower limb ulcers secondary to chronic venous disease (CVD) are a significant public health problem in Brazil and account for about 70% of these ulcers. Despite recent technological advances and the various therapeutic options for treatment of these chronic injuries, several factors may be involved in resistance to treatment. Dystrophic calcinosis cutis (DCC) is a rare and often underdiagnosed condition that, when in conjunction with CVD, may be associated with a refractory healing process. In this article, we report a case of DCC in a patient with CVD and discuss its etiology, pathophysiology and possible treatment options.

Resumo As úlceras de perna são as complicações cutâneas mais comuns em pacientes com anemia falciforme. Acometem principalmente indivíduos homozigotos e são lesões de difícil cicatrização e recidivantes, com impactos físicos, psicológicos e econômicos. Neste trabalho, discutimos a apresentação clínica, o diagnóstico, a fisiopatologia das úlceras falcêmicas e as suas implicações sobre a terapêutica.
Abstract Leg ulcers are the most common cutaneous complication of sickle cell disease. These lesions occur mainly in homozygous forms, are slow to heal and often relapse, causing negative physical, emotional, and economic impacts. In this paper, we discuss the clinical presentation, diagnosis, and pathophysiology of sickle cell leg ulcers and their implications for treatment.

BACKGROUND: Chronic leg ulcer may have an impact on patients' quality of life. OBJECTIVES: This study aimed to identify the impact of leg ulcers on patient's quality of life using the Dermatology Life Quality Index and to define the main factors correlated with this perception. METHOD: Cross-sectional, non-probabilistic sampling study. We included patients with chronic leg ulcers being treated for at least 3 months. A sociodemographic and clinical survey was conducted to assess the profile of the ulcers. We administered a screening for depressive symptoms and the Dermatology Life Quality Index. We performed a descriptive statistical analysis, chi-square test and Mann-Whitney test for categorical data, Pearson for numeric variables, and multiple regression for categorical data. RESULTS: Forty-one patients were assessed. Their mean age was 61.78 years. Venous ulcers (48.8%) were the most prevalent. Seventy-three percent of the sample perceived no impact/low impact on quality of life in the past week, and 26.8% perceived moderate/high impact. A multiple regression analysis identified the causes of lesion, pain related to the ulcers, time of onset, and severity of the depressive symptoms as the variables that had an influence on quality of life. CONCLUSIONS: The majority of the sample perceived low or no impact of the condition on the quality of the life. The variables etiology of the lesion (p<0.001), pain related to the ulcers (p=0.001), time of onset (p=0.006), and severity of the depressive symptoms (p<0.001) had an influence on the quality of life, suggesting the need for further studies with more robust designs to confirm the causal relationship between these characteristics and quality of life. .

A úlcera venosa crônica de membros inferiores é extremamente desgastante para o paciente e familiares, deteriorando a qualidade de vida e a produtividade das pessoas. Apesar de ser um problema comum nas unidades de saúde, as úlceras venosas não possuem tratamento adequado na maioria dos serviços devido principalmente ao desconhecimentode sua fisiopatologia e dos métodos terapêticos. Entre as medidas terapêuticas complexas descrita na literatura, a prevenção e o diagnóstico precoce são as etapas primordiais para o tratamento adequado desses pacientes, minimizando as sequelas físicas e psicológicas de uma lesão ulcerada em membros inferiores...
The lower limbs chronic venous ulcers are extremely stressful for patients and their families due to the physical limitation and the need of special care caused by that disease, which is responsible for the decrease of their life quality and productivity. Despite being a common problem in health care units,venous ulcers do not have adequate treatment in most of these specialized services mainly because of the ignorance of pathophysiology and therapists. Among the complex therapeutic measures described inthe literature, prevention and early diagnosis are the primary steps of a proper treatment; minimizing, thus,the physical and psychological consequences brought to lower limb ulcerations...

Las angiodermatitis necróticas se caracterizan por la aparición de úlceras en las piernas, dolorosas y rebeldes a los tratamientos en pacientes de edad avanzada e hipertensos. Presentamos un paciente masculino de 61 años de edad, con hipertensión arterial inestable de 11 años de evolución (220/120 mmHg), tratado con varias y múltiples drogas antihipertensivas por lo que frecuentemente tenía crisis de hipotensión. En los últimos 5 años desarrolló una lesión cutánea que consistía en una extensa placa eritematosa y numerosas ulceraciones, localizada en la cara externa de la pierna izquierda. Se ha propuesto que la causa principal reside en la microcirculación cutánea. La caída de la tensión arterial aumenta la hipoxia al disminuir el flujo de sangre con un aumento del oxígeno cuando ocurre la re-perfusión, resultando en una lesión por oxidación. En nuestro paciente, al controlar las crisis hipotensivas causadas por la medicación, mejoró la perfusión de la piel, con la cura de la lesión en aproximadamente un año
