Leg ulcer and osteomyelitis due to methicillin-susceptible Staphylococcus aureus infection after fracture repair treatment: a case highlighting the p…

2015

Prostaglandins appear to reduce biofilm formation and chronicization of infections, and stimulate a rapid and effective clearance of infecting micro-organisms. We report a case of recovery from methicillin-susceptible Staphylococcus aureus (MSSA) osteomyelitis after multidisciplinary management with antibiotics, anti-thrombotics and prostaglandin E1 (PGE1) vasodilator, in a patient with tibial plateau fracture repaired with internal fixation devices. A 47-year-old HIV-negative male with chronic ulcer on the proximal third of the left leg was admitted to the Orthopaedic Unit of the Orestano Clinic in Palermo, Italy, for suspected osteomyelitis. A biopsy of the skin ulcer and blood cultures w…

The treatment of venous leg ulcers: a new therapeutic use of iloprost

2007

Background: We conducted a study using an intravenous (i.v.) infusion of iloprost in the treatment of venous ulcers to verify whether the association of i.v. iloprost + local therapy + elastic compression has a favorable effect when compared with traditional treatment with local therapy and elastic compression. Study Design: We evaluated the effects of iloprost in 98 consecutive patients with noncomplicated venous ulcers of lower limbs subdivided into 2 groups: the first group (48 patients) received iloprost in saline solution for 3 weeks and the second group (50 patients) received a venous infusion of a saline solution. The patients were examined at baseline time 0 (first visit) and then a…

Hypothetical molecular mechanisms by which local iron overload facilitates the development of venous leg ulcers and multiple sclerosis lesions.

2008

Summary This paper presents a hypothetical model of role for iron in the development of venous leg ulcers and multiple sclerosis. Elevated concentrations of iron were found in the skin affected by venous hypertension and also in the areas of brain with multiple sclerosis lesions. Individuals with hemochromatosis gene (HFE) mutations: C282Y and H63D, which result in a less efficient transport of iron by macrophages, are characterized by an increased risk for venous leg ulcer and multiple sclerosis. Multiple sclerosis is a T cell-mediated disease, and T cells probably participate in the development of venous ulcers. This deleterious role of ferric ions could be related to the regulation of T …

A potential role of interferon-gamma in the pathogenesis of venous leg ulcers.

2005

Venous leg ulcer is the most severe expression of chronic venous insufficiency. Venous ulcerations are always associated with venous ambulatory hypertension, but the exact mechanism leading from pathological hemodynamics in venous circulation to the necrotic lesions in the skin still remains undiscovered. It has been shown that tissue injury in venous ulcer patients was induced by leukocytes. However, though infiltrating leukocytes have at their disposal a powerfully cytotoxic arsenal, it has not been discovered which molecular mechanisms may contribute to the skin damage. The search for this hypothetical factor responsible for the development of ulceration should be focused on mechanisms l…

Behaviour of the plasma concentration of gelatinases and their tissue inhibitors in subjects with venous leg ulcers.

2015

Venous leg ulcers are common in subjects with chronic venous insufficiency. The increased intraluminal pressure causes alteration of the skin microcirculation, leukocyte activation and release of proteolytic enzymes leading to ulceration. An impaired expression and activity of matrix metalloproteases (MMPs) and their tissue inhibitors (TIMPs) might influence extracellular matrix degradation and deposition in chronic venous ulcers with the failure of the healing process. Our aim was to evaluate plasma concentration of gelatinases (MMP-2 and MMP-9) and their inhibitors (TIMP-1 and TIMP-2) in subjects with venous leg ulcers before and after the compression therapy. We enrolled 36 subjects (12 …

Owrzodzenie podudzia związane z niewydolnością żyły mięśnia brzuchatego łydki - opis przypadku

2008

Przedstawiono przypadek chorego z żylnymi owrzodzeniami goleni na tle niewydolności żyły mięśnia brzuchatego łydki z układem refleksowym typu „enigma of the gastrocnemius vein”. Operacja polegała na wybiórczym podwiązaniu niewydolnego perforatora łączącego żyłę mięśnia brzuchatego łydki z żyłą odstrzałkową. Po operacji owrzodzenia wygoiły się oraz ustąpił refluks w układzie żyły mięśnia brzuchatego łydki. Omówiono również taktykę operacji u chorych z żylakami towarzyszącymi niewydolności żyły mięśnia brzuchatego łydki.

Multicentre Study of Chronic Wounds Point Prevalence in Primary Health Care in the Southern Metropolitan Area of Barcelona

2021

Background: Chronic wounds give rise to major costs and resource consumption in health care systems, due to their protracted healing time. Incidence and prevalence data are scarce or nonexistent in community settings. Objective: The aim of the present epidemiological study was to analyse and determine the prevalence of chronic wounds in the community in the south of the province of Barcelona (Spain). Design: A cross-sectional, multicentre secondary data analysis study was conducted in the community (excluding nursing homes) in Barcelona between 16 April and 13 June 2013. It included 52 primary care centres that serve a total population of 1,217,564 inhabitants. Results: The observed prevale…

Sequential and combined treatment of prolidase deficiency leg ulcers

2010

Background The Authors report a case of chronic cutaneous lesions in a patient affected by prolidase deficiency, a rare disorder inherited through an autosomal recessive gene (50 cases reported ). The enzyme prolidase is widely distributed throughout the body and it is important in the recycling of proline and hydroxyproline. Among the clinical presentations, the most striking manifestation is the skin fragility with leg ulceration (see Table ​Table11) Table 1 Clinical signs of prolidase deficiency The deficiency of the enzyme prolidase is responsible for massive loss of proline in the urine which is estimated to be as high as 3 g/die. The diagnosis is ascertained by iminopeptiduria greater…

Clinical meaning of incompetent perforators in the setting of post-thrombotic syndrome commentary

2015

In this issue of Phlebological Review Zolotukhin et al. [1] present the results of their study on recurrence of venous leg ulcers in post-thrombotic patients after endovenous laser ablation of incompetent lower leg perforators. They have found that not only the recurrence rate of these perforators was very high, but also that the procedure did not reduce the ulcer recurrence. This lack of clinical efficacy in terms of recurrence was different from the results of the well-known ESCHAR study [2]. In the ESCHAR study surgical ablation of incompetent superficial veins resulted in less frequent recurrences. From a hemodynamic and pathophysiological point of view a thermal ablation (such as laser…
