OBJECTIVE The present study was undertaken to compare the predictive values of transcutaneous oxygen tension (TcPO2) and toe blood pressure (TBP) measurements for ulcer healing in patients with diabetes and chronic foot ulcers. RESEARCH DESIGN AND METHODS Investigated prospectively were 50 diabetic patients (37 men) with chronic foot ulcers. The age was(More)
BACKGROUND Preterm birth is a risk factor for blood pressure (BP) elevation already at young age. The mechanisms are unknown. Low skin capillary density and impaired endothelial function characterize adults with hypertension. OBJECTIVES To investigate the early relationships between BP, capillary density and endothelial function after very preterm birth.(More)
The aim of the present study was to investigate if diabetes negatively influences the skin microvascular reactivity in the toes of patients with peripheral vascular disease (PVD). Twenty healthy subjects, 20 diabetic, and 20 non-diabetic patients with PVD participated. One foot in each subject was investigated. The patient groups were matched for age, sex,(More)
BACKGROUND The cause of diabetic foot ulcers is multifactorial, e.g., neuropathy and angiopathy, leading to functional disturbances in the macrocirculation and skin microcirculation. Adequate tissue oxygen tension is an essential factor in infection control and wound healing. Hyperbaric oxygen (HBO) therapy, daily sessions of oxygen breathing at 2.5-bar(More)
We investigated the effects of statin treatment on platelet-derived microparticles (PMPs) and thrombin generation in atherothrombotic disease. Nineteen patients with peripheral arterial occlusive disease were randomised to eight weeks of treatment with atorvastatin or placebo in a cross-over fashion. Expression of GPIIIa (CD61), P-selectin (CD62P), tissue(More)
OBJECTIVE Chronic foot ulcers are a common, severe, and expensive complication threatening life and limb in patients with diabetes. The aim of the present study was to investigate the effect of dalteparin on ulcer outcome in patients with diabetes, peripheral arterial occlusive disease, and chronic foot ulcers. RESEARCH DESIGN AND METHODS A total of 87(More)
Ten diabetic patients with peripheral arterial occlusive disease, peripheral polyneuropathy and chronic foot ulcers were given 2500 U low molecular weight heparin (Fragmin, Kabi-Pharmacia AB, Sweden) subcutaneously once a day during 8 weeks. The mean age was 63 (47-80) years and the mean duration of foot ulcers 8 (4-12) months. All patients had previously(More)
INTRODUCTION Flow cytometry (FCM) is the most commonly used method for detection of platelet-derived microparticles (PDMPs), but it is poorly standardized and mainly used for "bedside" analyses in fresh samples. If PDMPs could be analyzed in previously frozen samples it would increase the usefulness of the method. However, cell membrane fragments from(More)
T he pathogenesis behind diabetic mi-croangiopathy is complex; both genetic (1–3) and metabolic factors (4 – 6) are clearly of importance. Recently, it has been demonstrated that not only patients with diabetes but also healthy individuals at risk for diabetes have functional vascular disturbances (7). These findings suggest that factors other than(More)
AIM Acute hemodynamic changes during hemodialysis may jeopardize the peripheral blood circulation in patients with end-stage renal disease (ESRD). The aim of the present study was to investigate the effects of three consecutive hemodialyses on peripheral micro- and macrocirculation in patients with ESRD. METHODS Twenty patients with ESRD were(More)
