Venous leg ulcer

María-Luisa Martínez, Eduardo Escario, Enrique Poblet, David Sánchez, Fernando-Francisco Buchón, Ander Izeta, Francisco Jimenez
BACKGROUND: A prominent role of hair follicle-derived cells in epidermal wound closure is now well established but clinical translation of basic research findings is scarce. Although skin punch grafts have been used as a therapeutic intervention to improve healing of chronic leg ulcers, they are normally harvested from nonhairy areas, thus not taking advantage of the reported role of the hair follicle as a wound-healing promoter. OBJECTIVE: We sought to substantiate the role of hair follicles in venous leg ulcer healing by transplanting hair follicle-containing versus nonhairy punch grafts...

A wound is damage of a tissue usually caused by laceration of a membrane, generally the skin. Wound healing is accomplished in three stages in healthy individuals, including inflammatory, proliferative, and remodeling stages. Healing of wounds normally starts from the inflammatory phase and ends up in the remodeling phase, but chronic wounds remain in an inflammatory stage and do not show progression due to some specific reasons. Chronic wounds are classified in different categories, such as diabetic foot ulcer (DFU), venous leg ulcers (VLU) and pressure ulcer (PU), surgical site infection (SSI), abscess, or trauma ulcers...

Depression slows wound healing in patients with chronic wounds. The prevalence of depressive symptoms differs in the literature and the current understandings of factors related to depression in patients with wounds have been limited. To investigate the prevalence of depressive symptoms and the associated factors in patients with wounds, we performed this retrospective study in which depressive symptoms were evaluated with the Patient Health Questionnaire 9-item (PHQ-9). Valid PHQ-9 scores were collected from 222 patients (112 males and 110 females; age: 64...

We report a case of pulsatile varicose veins successfully managed by endovenous laser treatment (EVLT) of the great saphenous vein (GSV). A 77-year-old woman taking an anticoagulant was transferred to our hospital for pulsatile varicose veins complicated with repeated venous bleeding from an ulcer of her left lower leg. Doppler echocardiography showed severe tricuspid regurgitation, and duplex ultrasonography revealed an arterial-like pulsating flow in the saphenofemoral junction and along the GSV, but an arteriovenous fistula, obstruction of the deep veins, and the distal incompetent perforators were not detected...

Human cathelicidin, LL-37, is small antimicrobial peptide, which reveals also some immunomodulatory and proangiogenic properties and, therefore, may promote wound healing. The expression of LL-37 is controlled by various factors, including vitamin D. Thus, any disturbances in vitamin D level may influence LL-37 production and, possibly, affect wound healing. Since deficiency of vitamin D was identified as a common problem in the population, this proof of concept study aimed to verify the relationship between serum levels of LL-37, vitamin D, and healing rate of venous leg ulcers...

INTRODUCTION AND OBJECTIVES: The benefits of using amniotic tissue in skin regeneration are well documented. Today, cryopreservation technology allows for better availability and maintenance of mesenchymal stem cells. This is of particular interest in treating the diabetic foot ulcer as this population has fewer mesenchymal stem cells. The objective of this case series investigation was to compare the efficacy of cryopreserved human amniotic stem cells in treating foot wounds of different etiologies...

UNLABELLED: Lower leg ulcers are characterized by a chronic and recurrent course, being considered as a difficult therapeutic problem. Based on epidemiological data chronic ulcers concern 0.2 to 2% of the Western European population. The above-mentioned problem affects women more often than men, and increases with age. Treatment and recurrence prevention methods remain under discussion and research. The aim of the study was to evaluate the early surgical treatment results of venous leg ulcers at the Department of Traumatology and Emergency Medicine, Medical University of Lublin...

Objective: Ulceration of free flaps in patients with venous insufficiency and/or lymphedema is an uncommon but challenging problem. We hypothesized that dehydrated human amnion/chorion membrane (Epifix) grafts would accelerate healing of these challenging ulcers. Methods: Retrospective analysis of prospectively acquired data identified 8 lower extremity free flaps with ulcerations in the context of venous insufficiency and/or lymphedema. The first 4 were flaps that had been treated with conservative wound care to healing...

BACKGROUND: The risk of deep venous thrombosis is elevated during pregnancy and the puerperium. Therapy is usually limited to conservative measures as invasive thrombus removal is feared because of possible complications. However, leg- or life-threatening situations require fast thrombus removal, and the long-term rate of post-thrombotic syndrome (PTS) may be reduced by venous recanalization. Our center's experience may give support to surgical venous thrombectomy (VT). METHODS: Between 1996 and 2016, all women who received VT for pregnancy-related deep venous thrombosis in our department were included...

Cytokines play important roles in the wound healing process through various signalling pathways. The JAK-STAT pathway is utilised by most cytokines for signal transduction and is regulated by a variety of molecules, including suppressor of cytokine signalling (SOCS) proteins. SOCS are associated with inflammatory diseases and have an impact on cytokines, growth factors and key cell types involved in the wound‑healing process. SOCS, a negative regulator of cytokine signalling, may hold the potential to regulate cytokine‑induced signalling in the chronic wound‑healing process...

Leg ulcers are a chronic condition. Healing can be long for venous ulcers and the risk of complications is significant. Infection is the most severe complication and can occur in the form of easily diagnosed acute bacterial dermohypodermitis that generally responds well to antibiotic treatment if given at an appropriate dose or in the form of localized infection that is more difficult to diagnosis. Indeed, no consensus has been reached in the literature on the clinical criteria to retain for the diagnosis of localized infection...
