Critical limb ischemia (CLI) is the presentation of end stage peripheral arterial disease and typically presents with rest pain, ulceration and gangrene. The outcome of conservative treatment is poor and often leads to amputations. Arterial revascularization plays an important role in amputation prevention. Unfortunately, a significant percentage of CLI patients cannot be revascularized and subsequently end up with a palliative amputation. This has led to the need and exploration of new treatment options in this no option subgroup of CLI...

BACKGROUND: Liver cirrhosis is associated with increased intrahepatic resistance due to hepatic fibrosis and exaggerated vasoconstriction. Recent studies have indicated that proton pump inhibitors (PPIs), in addition to acid suppression, modulate vasoactive substances and vasoresponsiveness. PPIs are frequently prescribed in patients with cirrhosis due to a higher prevalence of peptic ulcers, however other impacts are unknown. METHODS: Liver cirrhosis was induced in Sprague-Dawley rats with common bile duct ligation (BDL)...

INTRODUCTION: Ingenol mebutate is an actinic keratosis treatment, which has a dual action mechanism. It allows a rapid cellular death and a severe inflammation. OBSERVATION: We report the case of a 75 years old patient with a rapidly growing tumor 5 weeks after application of ingenol mebutate on typical actinic keratosis. Histological analysis after surgical excision showed an invasive squamous cell carcinoma (SCC); with aggressiveness signs: perineural infiltration and vascular permeation...

Identifying sickle cell disease patients at high risk of complications could lead to personalized treatment and better prognosis but despite many advances prediction of the clinical course of these patients remains elusive. We propose a system-type approach to discover profiles of multiple, common biomarkers that correlate with morbidity and mortality in sickle cell disease. We used cluster analysis to discover 17 signatures of 17 common circulating biomarkers in 2320 participants of the Cooperative Study of Sickle Cell Disease, and evaluated the association of these signatures with risk for stroke, pain, leg ulceration, acute chest syndrome, avascular necrosis, seizure, death, and trend of fetal hemoglobin and hemolysis using longitudinally collected data...

Mechanical thrombectomy (MT) is the gold standard treatment for large vessel occlusion (LVO) stroke of the anterior circulation. Whether MT can also be effectively and safely performed in early recurrent LVO is largely unclear. We present the case of a middle-aged patient who was successfully treated by MT for right proximal middle cerebral artery (MCA) occlusion with excellent outcome. One day after discharge (9 days after the first MT), the patient was readmitted with wake-up stroke. MRI again revealed right proximal MCA occlusion with severe diffusion-perfusion mismatch...

Reactive species of oxygen (ROS), responsible for oxidative stress, accumulate in various tissues damaged by burns, decubitus ulcers, and vascular lesions. Antioxidants play an important and well-documented role in healing of chronic and acute wounds. Rigenase® , a specific extract of Triticum vulgare manufactured by Farmaceutici Damor, is employed in products used for the regeneration of tissue injuries. In this work, we show that Rigenase® exhibits a scavenging effect toward free radicals, thus pointing to its relevant antioxidant activity...

Purpose: This study investigated the validity of the Charlson comorbidity index (CCI) as a predictor of periodontal disease (PD) over a 12-year period. Methods: Nationwide representative samples of 149,785 adults aged ≥60 years with PD (International Classification of Disease, 10th revision [ICD-10], K052-K056) were derived from the National Health Insurance Service-Elderly Cohort during 2002-2013. The degree of comorbidity was measured using the CCI (grade 0-6), including 17 diseases weighted on the basis of their association with mortality, and data were analyzed using multivariate Cox proportional-hazards regression in order to investigate the associations of comorbid diseases (CDs) with PD...

Penetrating aortic ulcer (PAU) is an acute aortic syndrome that can proceed to life-threatening aortic dissection or even aortic rupture. Isolated iliac aneurysms are relatively rare and often asymptomatic due to their deep pelvic location but are frequently associated with high mortality with rupture. We report a case of a 68-year-old man with a symptomatic penetrating ulcer in the descending aorta and an asymptomatic right iliac aneurysm involving the common and internal iliac arteries. The patient was successfully treated by endovascular repair in a single-stage manner using stent grafts in the descending aorta and right common iliac artery after coil embolization of the right internal iliac artery...

Introduction: Anti-endothelial cell antibodies (AECA) recognize endothelial cell proteins and are thought to play an important role in vascular damage observed in systemic scleroderma (SSc) and many other autoimmune diseases. In SSc, AECA were found to be more common in patients with pulmonary hypertension, digital ulcers and nailfold capillaroscopic changes. Until now, there have been no studies examining the association between AECA positivity with the activity and duration of the disease...

BACKGROUND: Single photon emission computed tomography (SPECT)/computed tomography (CT) imaging allows for assessment of skeletal muscle microvascular perfusion but has not been quantitatively assessed in angiosomes, or 3-dimensional vascular territories, of the foot. This study assessed and compared resting angiosome foot perfusion between healthy subjects and diabetic patients with critical limb ischemia (CLI). Additionally, the relationship between SPECT/CT imaging and the ankle-brachial index-a standard tool for evaluating peripheral artery disease-was assessed...

An organized series of complicated biological and molecular phenomena is required for normal skin wound healing. These processes depend on normal cellular responses to cytokines, growth factors, and other mediators, such as clotting factors, prostaglandins, free radicals, and nitric oxide. In diabetic ulcers, impaired responses to these molecules lead to abnormalities in vascularization, innervation, matrix reconstruction, and reepithelialization of wounds. keratinocyte migration and proliferation on an extracellular matrix is critical in reepithelialization, but the response to growth factors is blunted in diabetes, including the insulin/IGF-1signaling axis...

Bechet's Disease is an inflammatory disease characterized by recurrent oral ulcers (OU), genital ulcers (GU) and uveitis which can develop a neurobehavioral syndrome, also defined as 'neuro-psycho- BS'. Depending on vascular or parenchymal lesions, the presentations could be varied. Due to sparse literature, there is no consensus on management of psychiatric illness comorbid with Bechet's disease. Bipolar disorder in Bechet's disease is extremely rare. Here, we are presenting a case of episodic exaggeration of Bipolar disorder along with Bechet's disease which imposed both clinical and management challenges...

We describe the case of a Type I diabetic patient with a refractory foot ulcer that remained unhealed for 2 years despite conventional therapy. Autologous adipose-derived stromal vascular fraction suspended in autologous platelet-rich plasma was applied to the wound, which completely healed within 1 month. The wound remained closed with no complications for a 2-year follow-up. Reporting of this and similar cases may lead to larger clinical trials that will prove the efficacy of this therapy that may offer accelerated healing and lessen the financial burden of more expensive therapeutic modalities...
