The Social and Economic Burden of Venous Leg Ulcers : Focus on the Role of Micronized Purified Flavonoid Fraction Adjuvant Therapy

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 …

Stress Echocardiography and Strain in Aortic Regurgitation (SESAR protocol): Left ventricular contractile reserve and myocardial work in asymptomatic…

2020

Objectives: To analyze left ventricular (LV) myocardial deformation and contractile reserve (CR) in asymptomatic patients with severe aortic regurgitation (AR) at rest and during exercise, and their correlation with functional capacity. Background: The natural history of chronic AR is characterized by a prolonged silent phase before onset of symptoms and overt LV dysfunction. Assessment of LV systolic function and contractile reserve has an important role in the decision-making of AR asymptomatic patients. Methods: Standard echo, lung ultrasound, and LV 2D speckle tracking strain were performed at rest and during exercise in asymptomatic patients with severe AR and in age- and sex-comparabl…

Obstructive Malformations of the Internal Jugular Vein

2021

Obstructive malformations of the internal jugular veins represent a relatively new clinical problem, which as of yet has not been fully understood. In normal subjects, the internal jugular vein is valveless, except for a single valve, situated just above the junction of this vein with the brachiocephalic vein. Usually, normal jugular valves exhibit a two-leaflet structure. Stenotic lesions of these veins were described for the first time in 2009 in a group of multiple sclerosis patients. The most common obstructive malformation of the internal jugular vein is a stenotic valve. There are several morphological types of such aberrant valves, comprising annular stenoses, valves with fused, reve…

An overview of randomized controlled trials on endovascular treatment for chronic cerebrospinal venous insufficiency in multiple sclerosis patients

2021

About ten years ago it was hoped that venous angioplasty for abnormal veins, primarily the internal jugular veins, will be a much awaited treatment for multiple sclerosis. Yet, a majority of randomized clinical trials on endovascular treatment for chronic cerebrospinal venous insufficiency did not reveal clinical efficacy of these procedures in multiple sclerosis patients. Still, a detailed analysis of these trials suggests that they were poorly designed, underpowered and endovascular techniques used were often far from being optimal. Nonetheless, even considering weak points of these trials, it can be concluded that venous angioplasty should not be used as a routine treatment modality in m…

Influence of chronic renal insufficiency on left ventricular diastolic function in hypertensives without left ventricular hypertrophy

Serum inhibin A, inhibin B, pro-alphaC, and activin A levels in women with idiopathic premature ovarian failure.

2003

Serum inhibin A, inhibin B, pro-alphaC, and activin A levels in 30 women with idiopathic premature ovarian failure (POF), 30 postmenopausal women, and 30 age-matched fertile women were determined. Women with POF showed low levels of inhibin A and inhibin B, but not of activin A, whereas the levels of pro-alphaC were significantly higher than in postmenopausal women. Thus, the circulating level of pro-alphaC could be a marker for assessing residual ovarian function in women with POF.

Endovascular treatment for chronic cerebrospinal venous insufficiency: is the procedure safe?

2010

Objectives The aim of this report is to assess the safety of endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI). Although balloon angioplasty and stenting seem to be safe procedures, there are currently no data on the treatment of a large group of patients with this vascular pathology. Methods A total of 564 endovascular procedures (balloon angioplasty or, if this procedure failed, stenting) were performed during 344 interventions in 331 CCSVI patients with associated multiple sclerosis. Results Balloon angioplasty alone was performed in 192 cases (55.8%), whereas the stenting of at least one vein was required in the remaining 152 cases (44.2%). There were no majo…

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.
