Extracellular matrix assessment of infected chronic venous leg ulcers: role of metalloproteinases and inflammatory cytokines.

Chronic venous ulcer (CVU) represents a dreaded complication of chronic venous disease (CVD). The onset of infection may further delay the already precarious healing process in such lesions. Some evidences have shown that matrix metalloproteinases (MMPs) are involved and play a central role in both CVUs and infectious diseases.

Fatal early peripheral post-reperfusion syndrome and the role of cutaneous signs.

The purpose of this report is to present the case of a 75-year-old male affected by right common femoral artery and abdominal aortic aneurysms. His clinical history was also characterised by post-ischaemic cardiomyopathy, arterial hypertension, chronic respiratory disease and peripheral arterial disease. We performed two surgical procedures: right femoral aneurysmectomy and femoro-femoral bypass and subsequently a femoro-femoral crossover bypass plus right femoro-popliteal bypass below the knee.

Male breast cancer manifesting as cephalic vein thrombosis.

Male breast cancer is an uncommon disease with a low annual prevalence in Western countries. Venous thromboembolism may be associated during malignancy of the breast. We report a 70-year-old man who presented with superficial vein thrombosis of right upper limb that predicted the diagnosis of breast invasive ductal carcinoma.

Cilostazol prevents foot ulcers in diabetic patients with peripheral vascular disease.

Diabetic patients are at high risk of foot ulcerations that may lead to limb amputations with important socio-economic impact. Peripheral vascular disease may be frequently associated in diabetes mellitus type II with its main symptom, intermittent claudication. Many studies reported the known efficacy of cilostazol in treating vascular claudication.

Chronic venous leg ulcers are associated with high levels of metalloproteinases-9 and neutrophil gelatinase-associated lipocalin.

Venous ulcers are related to dysfunctions in extracellular matrix. Both matrix metalloproteinases (MMP) and neutrophil gelatinase-associated lipocalin (NGAL) could play a role in the healing process in patients with chronic venous ulcers. We evaluated the role of MMP-9 and NGAL in the healing process in venous ulceration.

Low molecular weight heparin improves healing of chronic venous ulcers especially in the elderly.

Venous ulcers are common, especially in the elderly, accounting for more than 50% of all lower extremity ulcers with important socioeconomic problems. Improving extracellular matrix functioning, by heparin administration, seems to be a way to support wound healing. A total of 284 patients with venous ulcers were recruited in a 4-year period.

Specific personality traits and coping styles predict affective symptoms in early post acute coronary syndrome inpatients.

Objective: Affective symptoms have adverse effects in hospital and long-term cardiac outcomes of post Acute Coronary Syndrome (ACS) patients. This study aims to identify personality traits and maladaptive coping strategies that could predict affective symptoms in early post-ACS patients.

Methods: Seventy patients undergoing revascularization procedures were examined within a week after their admission by means of the Hospital Anxiety-Depression Scale.

Semantic similarity analysis of protein data: assessment with biological features and issues.

The integration of proteomics data with biological knowledge is a recent trend in bioinformatics. A lot of biological information is available and is spread on different sources and encoded in different ontologies (e.g.

The optimal dose of ribavirin for chronic hepatitis C: From literature evidence to clinical practice: The optimal dose of ribavirin for chronic hepatitis C.

Approximately 170 million people worldwide are chronically infected by hepatitis C virus (HCV), which can result in progressive hepatic injury and fibrosis, culminating in cirrhosis and end-stage liver disease. The benchmark therapy for untreated HCV patients is a combination of pegylated interferon-alpha (PEG-IFN) and ribavirin (RBV). Several studies have suggested several potential new approaches to improve HCV therapy-optimization of the dose and duration of RBV therapy, accompanied by careful clinical management, is crucial in ensuring the greatest likelihood of a long response to therapy.
