    Full Text Available Christopher A Latz,1 Kellie R Brown,2 Ruth L Bush11Texas A&M Health Science Center College of Medicine, Bryan, TX, USA; 2Medical College of Wisconsin, Milwaukee, WI, USAAbstract: Compression therapy has been the mainstay for the treatment of lower extremity edema, venous insufficiency, and particularly, venous ulcerative disease. Though modern surgical treatments exist, none are completely effective without good compressive options to allow for decreased swelling and better oxygenation of damaged tissues. This review article will describe the pathophysiology and presentation of lower extremity venous ulcerations, as well as current options for compression therapy. The benefits, along with the major pitfall of nonadherence, will also be discussed.Keywords: venous disease, chronic venous insufficiency, venous ulceration

    The aim of this study was to systematically review the current evidence and determine whether there is a clinical benefit for using pharmacological agents as adjunctive treatment for chronic venous ulcers. A systematic review of the MEDLINE and EMBASE (from 1 January 1947 through 15 August 2013) and Cochrane databases (from inception through 15 August 2013) was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Inclusion criteria were all randomised controlled trials investigating pharmacological adjuncts for the treatment of venous ulcers with a minimum sample size of 20 patients for each treatment arm. Ten relevant articles were identified; one pilot randomised controlled trial and four Cochrane reviews were included. Pentoxifylline, aspirin, sulodexide, mesoglycan, flavonoids, thromboxane A2 antagonist (ifetroban), zinc, prostaglandin and prostacyclin analogues were the drugs reviewed. Pentoxifylline was found to be more effective than placebo in terms of complete ulcer healing or in causing a significant improvement (greater than 60% reduction in ulcer size) (RR 1.70, 95% CI 1.30 to 2.24). Aspirin and flavonoids show potential to be effective adjuncts but methodological shortcomings and issues with bias limit the validity of results from trials involving each of these drugs, respectively. There was no significant difference between placebo and Ifetroban and likewise pooled results from trials investigating sulodexide and zinc showed no benefit in comparison to placebo. Many systemic pharmacological agents have been investigated as adjuncts to venous ulcer healing; however, pentoxifylline (400 mg, three times a day) is currently the only drug that has promising evidence to support its use. Other compounds are in early stage research. © The Author(s) 2015.

    Full Text Available Sara F Maher Physical Therapy Program, Department of Healthcare Sciences, Wayne State University, Detroit, MI, USA Abstract: Topical zinc has been used in the treatment of wounds for over 3,000 years, and is reported to have antiseptic, astringent, anti-inflammatory, antimicrobial, and wound healing properties. Fourteen studies were identified and reviewed, to assess the efficacy of this treatment modality as either a bandage or skin protectant in the treatment of venous ulcers. The authors of three studies reported improved healing time or success rate in wounds treated with zinc-based products. However, the authors of one study attributed the faster healing rate mainly to the extra compression (that improved venous blood return, delivered by the non-elastic paste bandage, and not by the zinc oxide alone. The quality of evidence is fair, as 50% of the studies were conducted prior to 2000 and 50% of the studies utilized fewer than 45 patients randomized to two or more groups. Other treatments have been reported to be more cost-effective than zinc, including hydrocolloids, four-layer compression systems, and CircAid Thera-boots. Finally, zinc was reported to be less comfortable, less easy to use, and caused increased pain, in comparison to other products on the market. This literature review, therefore, demonstrated that current evidence is insufficient to determine the effectiveness of zinc-based products in the treatment of venous wounds. Future research is needed focusing on larger, high-quality trials with an emphasis on quality of life issues and cost-effectiveness of treatment.

    Chronic venous leg ulcers (CVLU) are chronic wounds, associated with long-standing venous hypertension, which have a poor prognosis for healing. In the process of wound healing the first step is represented by platelet aggregation and subsequent release of growth factors and other mediators, which play a key role in the repair response. Platelet gel (PG), a hemocomponent obtained by mixing platelets, thrombin, and calcium, is able, when applied topically, to release platelet mediators that likely favor CVLU healing. However, unstandardized protocols have been described in studies utilizing PG for the regeneration of a number of tissues, including CVLU; the relative clinical outcomes were hence highly variable. In our experience the topical use of PG, together with the strict adherence to the principles of good wound care, quickly promoted increased granulation tissue, followed by a complete CVLU epithelization. Although further studies and trials are needed to establish the major outcome affecting rules for optimal indications, preparation, and use of PG for CVLU treatment, PG can be undoubtedly considered a useful tool, able to improve the management of CVLU.

    Aim of the present comparative clinical study was to demonstrate the efficacy of the topical application of mesoglycan, a profibrinolytic agent, for healing of leg ulcers in patients with chronic venous insufficiency. Forty patients, observed in our outpatients department, with venous leg ulcers have been randomized in two groups of twenty subjects, each treated with topical application of mesoglycan (1 or 2 vials/day) or vegetal stimulins and followed for two months, with controls after 15, 30 and 60 days. At the end of the observation period, ulcer healing rate was 95% in the mesoglycan group, while a lower healing rate was obtained in the stimulins group (80%). The present study confirms previous clinical experiences with mesoglycan and suggests its application in the topical treatment of venous ulcers.

    Venous disease is the most common cause of chronic leg ulceration and represents an advanced clinical manifestation of venous insufficiency. Due to their frequency and chronicity, venous ulcers have a high socioeconomic impact, with treatment costs accounting for 1% of the health care budget in Western countries. The evaluation of patients with venous ulcers should include a thorough medical history for prior deep venous thrombosis, assessment for an hypercoagulable state, and a physical examination. Use of the CEAP (clinical, etiology, anatomy, pathophysiology) Classification System and the revised Venous Clinical Severity Scoring System is strongly recommended to characterize disease severity and assess response to treatment. This venous condition requires lifestyle modification, with affected individuals performing daily intervals of leg elevation to control edema; use of elastic compression garments; and moderate physical activity, such as walking wearing below-knee elastic stockings. Meticulous skin care, treatment of dermatitis, and prompt treatment of cellulitis are important aspects of medical management. The pharmacology of chronic venous insufficiency and venous ulcers include essentially two medications: pentoxifylline and phlebotropic agents. The micronized purified flavonoid fraction is an effective adjunct to compression therapy in patients with large, chronic ulceration.

    To investigate the effectiveness of autologous bone marrow mononuclear cells transplantation on lower limb chronic venous ulcer. Between May 2009 and September 2010, 17 patients with lower limb chronic venous ulcer were treated with autologous bone marrow mononuclear cells transplantation (transplantation group) and 10 patients treated without cells transplantation served as control group. In the transplantation group, there were 9 males and 8 females with age of (33.3 +/- 6.1) years, including 11 cases of simple great saphenous vein varicosity and 6 cases of chronic venous insufficiency; the area of ulcer was (4.39 +/- 2.46) cm2; and the duration of ulcer ranged from 3 months to 6 years. In the control group, there were 4 males and 6 females with age of (39.2 +/- 10.3) years, including 7 cases of simple great saphenous vein varicosity and 3 cases of chronic venous insufficiency; and the area of ulcer was (5.51 +/- 2.63) cm2; and the duration of ulcer ranged from 3 months to 2 years. All patients in both groups were classified as C6 according to clinical etiology anatomy pathophysiology (CEAP) classification. No significant difference was found in the general data between 2 groups (P > 0.05). The healing process of ulcer was observed. The granulation tissue was harvested for HE staining before operation and at 3 days after operation in the transplantation group. The microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression of ulcer granulation tissue were observed. In the transplantation group, ulcer healing was accelerated; complete healing was observed in 15 cases, partial healing in 1 case, and no healing in 1 case with the median healing time of 22 days. However, in the control group, the healing process was slower; complete healing of ulcer was observed in 7 cases and no healing in 3 cases with the median healing time of 57.5 days. There was significant difference in the healing time between 2 groups (Z = 0.001 4, P = 0.0027). HE

    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. Two groups of patients were enrolled to evaluate the expression of MMPs in infected ulcers and the levels of inflammatory cytokines as well as their prevalence. Group I comprised 63 patients (36 females and 27 males with a median age of 68·7 years) with infected CVUs, and group II (control group) comprised 66 patients (38 females and 28 males with a median age of 61·2 years) with non-infected venous ulcers. MMP evaluation and dosage of inflammatory cytokines in plasma and wound fluid was performed by means of enzyme-linked immunosorbent assay test; protein extraction and immunoblot analysis were performed on biopsied wounds. The first three most common agents involved in CVUs were Staphylococcus aureus (38·09%), Corynebacterium striatum (19·05%) and Pseudomonas aeruginosa (12·7%). In this study, we documented overall higher levels of MMP-1 and MMP-8 in patients with infected ulcers compared to those with uninfected ulcers that showed higher levels of MMP-2 and MMP-9. We also documented higher levels of interleukin (IL)-1, IL-6, IL-8, vascular endothelial growth factor and tumour necrosis factor-alpha in patients with infected ulcers with respect to those with uninfected ulcers, documenting a possible association between infection, MMP activation, cytokine secretions and symptoms. The present results could represent the basis for further studies on drug use that mimic the action of tissue inhibitors of metalloproteinases in order to make infected CVU more manageable.

    Leg ulcers usually occur secondary to venous reflux or obstruction, but 20% of people with leg ulcers have arterial disease, with or without venous disorders. Between 1.5 and 3.0/1000 people have active leg ulcers. Prevalence increases with age to about 20/1000 in people aged over 80 years. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of standard treatments, adjuvant treatments, and organisational interventions for venous leg ulcers? What are the effects of advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 101 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: compression bandages and stockings, cultured allogenic (single or bilayer) skin replacement, debriding agents, dressings (cellulose, collagen, film, foam, hyaluronic acid-derived, semi-occlusive alginate), hydrocolloid (occlusive) dressings in the presence of compression, intermittent pneumatic compression, intravenous prostaglandin E1, larval therapy, laser treatment (low-level), leg ulcer clinics, multilayer elastic system, multilayer elastomeric (or non-elastomeric) high-compression regimens or bandages, oral treatments (aspirin, flavonoids, pentoxifylline, rutosides, stanozolol, sulodexide

    Chronic leg ulcers (CLUs) are a common occurrence in the western population and are associated with a negative impact on the quality of life of patients. They also cause a substantial burden on the health budget. The pathogenesis of leg ulceration is quite heterogeneous, and chronic venous ulceration (CVU) is the most common manifestation representing the main complication of chronic venous disease (CVD). Prevention strategies and early identification of the risk represent the best form of management. Fuzzy logic is a flexible mathematical system that has proved to be a powerful tool for decision-making systems and pattern classification systems in medicine. In this study, we have elaborated a computerised prediction system for chronic leg ulcers (PredyCLU) based on fuzzy logic, which was retrospectively applied on a multicentre population of 77 patients with CVD. This evaluation system produced reliable risk score patterns and served effectively as a stratification risk tool in patients with CVD who were at the risk of developing CVUs.

    The purpose of this cross-sectional descriptive pilot study was to describe daily intake of select nutrients important for efficient wound healing and general health in a sample of older adults (64.25 ± 9.49 years of age) with chronic venous leg ulcers (CVLUs; N = 12), compared to recommended dietary allowances (RDA). Anthropometric data were also collected. Compared to RDA, participants on average consumed lower vitamin C (60.03 ± 49.73 mg/d) and higher sodium (3197.07 ± 1455.04 mg/d), sugar (181.21 ± 115.45 g/d), and saturated fat (33.75 ± 1.06 g/d). They also demonstrated a relatively high plasma n-6/n-3 polyunsaturated fatty acid ratio, a biomarker of inflammation (11.25 ± 1.99). The mean body mass index indicated extreme obesity (41.48 ± 11.47). A multidisciplinary treatment approach that includes routine dietary assessments followed by tailored dietary interventions may improve wound healing and long-term health outcomes in this population.

    to assess the effect of treatment with mesoglycan, a sulphated polysaccharide compound, on the healing of venous ulcers. Design randomised, placebo-controlled, double-blind, multicentre trial. non-diabetic outpatients with chronic venous insufficiency confirmed by duplex ultrasound, normal ankle/arm pressure index and presence of a leg ulcer were eligible. Patients were randomised to mesoglycan, 30 mg/day intramuscularly for 3 weeks followed by 100 mg/day orally, or matching placebo, as an adjunct to compression therapy and topical wound care. Treatment and observation were continued until complete ulcer healing or for 24+/-1 weeks. Time to ulcer healing and healing rates were estimated with the Kaplan-Meier method. One hundred and eighty-three patients were randomised and included in the analysis (92 mesoglycan, 91 placebo). Median ulcer area upon inclusion was 3.6 cm(2)in the mesoglycan group and 3.9 cm(2)in the placebo group. The estimated time to heal 75% of the patients was 90 days on mesoglycan versus 136 days on placebo, while the cumulative rate of healing by the end of observation was 97% versus 82%, respectively. The difference in favour of mesoglycan was statistically significant (p mesoglycan was 1.48. The rate of adverse events was 7/92 on mesoglycan and 6/91 on placebo. treatment with mesoglycan in addition to established venous ulcer therapy resulted in a significantly faster and more frequent ulcer healing, and did not raise any safety concerns.

    In 2012 we reported promising results from a phase 2 clinical trial of HP802-247, a novel spray-applied investigational treatment for chronic venous leg ulcers consisting of human, allogeneic fibroblasts and keratinocytes. We now describe phase 3 clinical testing of HP802-247, its failure to detect efficacy, and subsequent investigation into the root causes of the failure. Two randomized, controlled trials enrolled a total of 673 adult outpatients at 96 centers in North America and Europe. The primary endpoint was the proportion of ulcers with confirmed closure at the end of 12 weeks of treatment. An investigation into the root cause for the failure of HP802-247 to show efficacy in these two phase 3 trials was initiated immediately following the initial review of the North American trial results. Four hundred twenty-one patients were enrolled in the North American (HP802-247, 211; Vehicle 210) and 252 in the European (HP802-247, 131; Vehicle 121) trials. No difference in proportion of closed ulcers at week 12 was observed between treatment groups for either the North American (HP802-247, 61.1%; Vehicle 60.0%; p = 0.5896) or the European (HP802-247, 47.0%; Vehicle 50.0%; p = 0.5348) trials. Thorough investigation found no likelihood that design or execution of the trials contributed to the failure. Variability over time during the trials in the clinical response implicated the quality of the cells comprising HP802-247. Concordance between the two separate, randomized, controlled trials with distinct, nonoverlapping investigative sites and independent monitoring teams renders the possibility of a Type II error vanishingly small and provides strong credibility for the unexpected lack of efficacy observed. The most likely causative factors for the efficacy failure in phase 3 was phenotypic change in the cells (primarily keratinocytes) leading to batch to batch variability due to the age of the cell banks.

    2005-11-01

    Recent histological and immunocytochemical analyses of venous leg ulcers suggest that lesions observed in the different stages of chronic venous insufficiency (CVI) may be related to an inflammatory process. This inflammatory process leads to fibrosclerotic remodeling of the skin and then to ulceration. The vascular network of the most superficial layers of the skin appears to be the target of the inflammatory reaction. Hemodynamic forces such as venous hypertension, circulatory stasis, and modified conditions of shear stress appear to play an important role in an inflammatory reaction accompanied by leukocyte activation which clinically leads to CVI: venous dermatitis and venous ulceration. The leukocyte activation is accompanied by the expression of integrins and by synthesis and release of many inflammatory molecules, including proteolytic enzymes, leukotrienes, prostaglandin, bradykinin, free oxygen radicals, cytokines, and possibly other classes of inflammatory mediators. The inflammatory reaction perpetuates itself, leading to liposclerotic skin and subcutaneous tissue remodeling. In light of the mechanisms of venous ulcer formation cited above, therapy in the future might be directed against leukocyte activation in order to diminish the magnitude of the inflammatory response. With this in mind, the attention of many investigators has been drawn to two different drugs with an anti-inflammatory effect: pentoxifylline and flavonoids.

    Sarcoidosis--a chronic, multisystem disease of unknown etiology characterized by noncaseating granulomas--may cause ulcerative lesions, particularly in African American women. A case of ulcerative sarcoidosis mimicking a venous ulcer is presented. The patient is a 44-year-old African American hypertensive, obese woman with a nonhealing medially based lower leg ulcer of 3 years' duration clinically consistent with a venous ulcer. The ulcer did not heal with compression therapy and pentoxifylline. Subsequent biopsies showed granulomatous inflammation consistent with sarcoidosis. When intralesional triamcinolone was added to compression therapy, the ulcer resolved after 3 months. Given its propensity toward formation on the lower extremities and ulcerative and atrophic appearance, ulcerative sarcoidosis should be considered in the differential diagnosis of a venous ulcer refractory to standard therapy, especially in African American women.

    The venous ulcer represents approximately 70% to 90% of inferior member ulcers, and the most common etiological factor is venous insufficiency, triggered by venous hypertension. Currently in Brazil there are several types of lasers used in physiotherapy, which benefit biological potential, emitting low power radiation, with anti-inflammatory, analgesic, healing and circulatory effects. This study aimed at the analysis of low level laser therapy effects (LLLT) on the process of tissue repair in chronic venous ulcers. We conducted a case study of a patient with a venous ulcer in the lateral region of the right inferior member. The patient underwent LLLT, which used a GaAlInP diode laser, with a wavelength of 660 nm and energy density of 4 J cm-2 applied punctually at the edges of the wound, with an average distance of 1 cm between the points with a pen-laser perpendicular wrapped in paper and a plastic wrap, keeping contact with the tissue. After four months of therapy and a total of 21 sessions, an improvement was noticeable in the gross appearance of the wound, but after a month and a half without therapy, the dimensions of the wound increased in length and width. Analyzing the results of this case study allows us to conclude that the LLLT GaAlInP (660 nm) with an energy density of 4 J cm-2, was not successful in the healing of venous ulcers.

    The revised guideline of 2013 is an update of the 2005 guideline "venous leg ulcer". In this special project four separate guidelines (venous leg ulcer, varicose veins, compression therapy and deep venous disorders) were revised and developed simultaneously. A meeting was held including representatives of any organisation involved in venous disease management including patient organizations and health insurance companies. Eighteen clinical questions where defined, and a new strategy was used to accelerate the process. This resulted in two new and two revised guidelines within one year. The guideline committee advises use of the C of the CEAP classification as well as the Venous Clinical Severity Score (VCSS) and a Quality of life (QoL) score in the assessment of clinical signs. These can provide insight into the burden of disease and the effects of treatment as experienced by the patient. A duplex ultrasound should be performed in every patient to establish the underlying aetiology and to evaluate the need for treatment (which is discussed in a separate guideline). The use of the TIME model for describing venous ulcers is recommended. There is no evidence for antiseptic or antibiotic wound care products except for a Cochrane review in which some evidence is presented for cadexomer iodine. Signs of infection are the main reason for the use of oral antibiotics. When the ulcer fails to heal the use of oral aspirin and pentoxifylline can be considered as an adjunct. For the individual patient, the following aspects should be considered: the appearance of the ulcer (amount of exudate) according to the TIME model, the influence of wound care products on moisturising the wound, frequency of changing compression bandages, pain and allergies. The cost of the dressings should also be considered. Education and training of patients t improves compliance with compression therapy but does not influence wound healing rates.

    2010-04-15

    Venous ulcer, also known as stasis ulcer, is the most common etiology of lower extremity ulceration, affecting approximately 1 percent of the U.S. population. Possible causes of venous ulcers include inflammatory processes resulting in leukocyte activation, endothelial damage, platelet aggregation, and intracellular edema. The primary risk factors for venous ulcer development are older age, obesity, previous leg injuries, deep venous thrombosis, and phlebitis. On physical examination, venous ulcers are generally irregular, shallow, and located over bony prominences. Granulation tissue and fibrin are typically present in the ulcer base. Associated findings include lower extremity varicosities, edema, venous dermatitis, and lipodermatosclerosis. Venous ulcers are usually recurrent, and an open ulcer can persist for weeks to many years. Severe complications include cellulitis, osteomyelitis, and malignant change. Poor prognostic factors include large ulcer size and prolonged duration. Evidence-based treatment options for venous ulcers include leg elevation, compression therapy, dressings, pentoxifylline, and aspirin therapy. Surgical management may be considered for ulcers that are large in size, of prolonged duration, or refractory to conservative measures.

    Venous ulcers are the most common ulcers of the lower limb. It has a high morbidity and results in economic strain both at a personal and at a state level. Chronic venous hypertension either due to primary or secondary venous disease with perforator paucity, destruction or incompetence resulting in reflux is the underlying pathology, but inflammatory reactions mediated through leucocytes, platelet adhesion, formation of pericapillary fibrin cuff, growth factors and macromolecules trapped in tissue result in tissue hypoxia, cell death and ulceration. Duplex scan with colour flow is the most useful investigation for venous disease supplying information about patency, reflux, effects of proximal and distal compression, Valsalva maneuver and effects of muscle contraction. Most venous disease can be managed conservatively by leg elevation and compression bandaging. Drugs of proven benefit in venous disease are pentoxifylline and aspirin, but they work best in conjunction with compression therapy. Once ulceration is chronic or the patient does not respond to or cannot maintain conservative regime, surgical intervention treating the underlying venous hypertension and cover for the ulcer is necessary. The different modalities like sclerotherapy, ligation and stripping of superficial varicose veins, endoscopic subfascial perforator ligation, endovenous laser or radiofrequency ablation have similar long-term results, although short-term recovery is best with radiofrequency and foam sclerotherapy. For deep venous reflux, surgical modalities include repair of incompetent venous valves or transplant or transposition of a competent vein segment with normal valves to replace a post-thrombotic destroyed portion of the deep vein.

    The aim of this study was to evaluate the cytotoxic effect of octenidine dihydrochloride/phenoxyethanol (OHP) found in vitro by conducting a randomized, double-blind controlled clinical study focusing on its safe and effective use in chronic venous leg ulcers. In total, 126 male and female patients were treated with either OHP (n = 60) or Ringer solution (n = 66). The treatment lasted over a period of maximum 12 weeks. For the assessment of the wound-healing process, clinical outcome parameters were employed, that is, time span until 100% epithelization, wound status and the wound surface area were analysed. Side effects were recorded during the study period. The median time to complete ulcer healing was comparable between the OHP and Ringer solution groups (92 versus 87 days; P = 0·952), without being influenced by wound size or duration of the target ulcer (P-values: 0·947/0·978). In patients treated with OHP, fewer adverse events (AEs) were observed compared with the Ringer group (17% versus 29% of patients reported 20 versus 38 AEs). OHP is well suitable for the treatment of chronic wounds without cytotoxic effects. Furthermore, OHP does not impair the wound healing in chronic venous ulcers. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

    Full Text Available BACKGROUND: Chronic ulcers affect roughly 60,000 Irish people, at a total cost of €600,000,000, or €10,000 per patient annually. By virtue of their chronicity, these ulcers also contribute a significant burden to tertiary outpatient vascular clinics. OBJECTIVE: We propose utilizing mobile phone technology to decentralise care from tertiary centres to the community, improving efficiency and patient satisfaction, while maintaining patient safety. METHODS: Bespoke mobile software was developed for Apples iPhone 4 platform. This allowed for the remote collection of patient images prospectively and their transmission with clinical queries, from the primary healthcare team to the tertiary centre. Training and iPhones were provided to five public health nurses in geographically remote areas of the region. Data were uploaded securely and user end software was developed allowing the review and manipulation of images, along with two way communication between the teams. Establishing reliability, patients were reviewed clinically as well as remotely, and concordance analysed. Qualitative data were collected through focus group discussion. RESULTS: From October to December 2011 eight patients (61-83 yrs, mean 75.3 yrs with chronic venous ulceration and their five public health nurses were recruited. Data were transmitted using 3 G, Edge, GPRS and WiFi, at a mean speed of 69.03 kps. Concordance was 100% for wound bed assessment, 80% for skin integrity/colour and 60% for exudate assessment. Focus group analysis explored the concept, practicalities and future applications of the system. CONCLUSIONS: With an evolving national data network, the secure transmission of clinical images is a safe alternative to regular clinic appointments for patients with chronic venous ulceration. With further development, and packaged as a freely downloadable application, this has the potential to support the community care of chronic wounds.

    Dormandy, J A

    In terms of prevalence, total cost and morbidity, venous leg ulcers are probably by far the most important type of ulcerations in the leg. The macrocirculatory defect leading to a raised ambulatory venous pressure is now accepted as a common initial pathologic pathway. Most current treatment modalities, such as surgery or external compression, are designed to control the macrovascular defect. However, it is the microcirculatory consequences of the venous hypertension that give rise to the trophic skin changes and ultimately to ulceration. At this microcirculatory level, pharmacotherapy may be a useful adjunct in the treatment of venous leg ulcers. The microcirculatory pathophysiologic changes include decreased fibrinolytic activity, elevated plasma fibrinogen, microcirculatory thrombi, and inappropriate activation of the white blood cells. The oxidative burst from the activated white cells probably plays a key role by releasing locally leukocyte-derived free radicals, proteolytic enzymes, cytokines, platelet-activating factor, and a number of other noxious mediators. An important additional component in recalcitrant venous ulcers is co-existing arterial disease, which is probably present in 15-20% of cases. Decreased arterial perfusion pressure will further aggravate the ischemic changes caused by the venous hypertension. Pentoxifylline downregulates leukocyte activation, reduces leukocyte adhesion, and also has fibrinolytic effects. A number of clinical studies have therefore been carried out to examine the clinical efficacy of pentoxifylline in treatment of venous leg ulcers. Probably the largest published placebo-controlled, double-blind randomized study was reported in 1990. In this study, 80 patients received either pentoxifylline 400 mg three times a day orally or matching placebo for 6 months or until their reference ulcer healed if this occurred sooner. Complete healing of the reference ulcer occurred in 23 of the 38 patients treated with pentoxifylline

    Venous ulceration is a complex and serious problem that affects 1-2% of the global elderly population (>65 years), and its incidence is constantly increasing. The population group with higher risk of development of venous ulceration is the elderly. These lesions have a significant negative impact on patients' quality of life. Our aim was to analyze the state of the art, starting with the medical literature review. The evidence supports that managing chronic wounds with a multidisciplinary wound care team significantly increases wound healing and reduces the severity of wound-associated pain and the required daily wound treatments compared with persons who are not managed by such a team.

    The aim of this study was to determine the efficacy, safety and cost-effectiveness of an octenidine-based wound gel in the treatment of chronic venous leg ulcers. For this purpose, 49 wounds were treated with either modern wound-phase-adapted dressings alone (treatment arm 1; n = 17), octenidine wound gel plus modern wound-phase-adapted dressings (treatment arm 2; n = 17) or octenidine wound gel alone (treatment arm 3; n = 15). During the study period of 42 days with dressing changes every 3-5 days, wound healing characteristics and treatment costs of different dressings were analysed. Wound size reduction was significantly better (P = 0·028) in both octenidine wound gel treatment arms compared to modern dressings alone with total reductions of 14·6%, 64·1% and 96·2% in treatment arms 1-3. Early wound healing was merely observed under octenidine wound gel treatment (n = 9), whereby lowest treatment costs were generated by octenidine wound gel alone (€20·34/dressing change). As a result, the octenidine wound gel is cost-effective and well suitable for the treatment of chronic venous leg ulcers, considering both safety and promotion of wound healing.

  5. Compression Stockings for Treating Venous Leg Ulcers

    Full Text Available Background. In order to treat venous leg ulcers, it is recommended to use high pressure compression (30–40 mmHg at the ankle. Compression stockings which are not operator dependant could be the best option because of their pressure control. However 30–40 mmHg compression stockings are often hard to put on. Putting two lower pressure compression stockings over each other could be a good therapeutic alternative. Objectives. To compare the in vitro pressures given by the manufacturers of 2 antiulcer kits with the in vivo interface pressures measured in healthy subjects and to evaluate the stiffness and friction indices from those kits based on the interface pressure in order to assess their clinical properties. Material and Methods. Using a Kikuhime pressure device, interface pressure was measured in 12 healthy subjects at the reference point B1. One stiffness index (Static Stiffness Index (SSI and a friction index have been calculated. Results. Mediven Ulcer kit gets the recommended pressures whereas Jobst’s Ulcer Care kit does not for treating a venous leg ulcer. Jobst’s Ulcer Care transmits entirely the pressure in relation to a friction index close to 1. Conclusion. This antiulcer kit study underlines that in vivo and in vitro pressures can be different (Jobst’s Ulcer Care kit and Mediven Ulcer kit. In order not to lose pressure, it is important to take into account the friction index when superimposing two stockings.

    Full Text Available BACKGROUND: The vegetal biomembrane has been used to treat cutaneous ulcers. OBJECTIVES: To assess the role of the vegetal biomembrane on the chronic venous ulcers treatment compared to treatment with collagenase cream. METHODS: Fourteen patients were selected to be treated with vegetal biomembrane and 7 with Fibrase®(CONTROL, followed clinically and photographically by the Wound Healing Index by ImageJ during 120 days and biopsied on the 1st and 30th days for histological examination. RESULTS: The vegetal biomembrane was better in promoting healing of the ulcers, especially on the inflammatory phase, confirmed by abundant exudation and wound debridement than the CONTROL group, on the 30th day. There was a greater tendency to angiogenesis followed by re-epithelialization with highest wound healing index on the 90th and 120th days. CONCLUSION: A combined analysis of clinical and histopathological findings suggests that the vegetal biomembrane acted as a factor inducing wound healing, especially on the inflammatory phase, confirmed by abundant exudation of the lesions promoting the transformation of the microenvironment of the chronic venous ulcers, and also stimulating angiogenesis and subsequent re-epithelialization.FUNDAMENTOS: A biomembrana vegetal tem sido usada para tratamento de úlceras cutâneas.

    Leg ulcerations are a common problem, with an estimated prevalence of 1% to 2% in the adult population. Venous leg ulcers are primarily treated in outpatient settings and often are managed by dermatologists. Recent advances in the diagnosis and treatment of leg ulcers combined with available evidence-based data will provide an update on this topic. A systematized approach and the judicious use of expensive advanced therapeutics are critical. Specialized arterial and venous studies are most commonly noninvasive. The ankle brachial pressure index can be performed with a handheld Doppler unit at the bedside by most clinicians. The vascular laboratory results and duplex Doppler findings are used to identify segmental defects and potential operative candidates. Studies of the venous system can also predict a subset of patients who may benefit from surgery. Successful leg ulcer management requires an interdisciplinary team to make the correct diagnosis, assess the vascular supply, and identify other modifiable factors to optimize healing. The aim of this continuing medical education article is to provide an update on the management of venous leg ulcers. Part I is focused on the approach to venous ulcer diagnostic testing.

    We report here two cases of men, aged 46 and 23 years, with refractory chronic venous leg ulcers in association with sex chromosome aberrations: one with a 47,XXY/48,XXXY karyotype (Klinefelter syndrome) and the other with a 47,XYY karyotype (Jacob syndrome). In both patients, the occurrence of leg ulcers was the reason for seeking medical care; their medical history was other-wise unremarkable. Chromosomal analyses were performed due to the unusually young age for development of venous leg ulcers. The pathophysiology behind the occurrence of venous leg ulcers in patients with numerical aberrations of the sex chromosomes is incompletely understood. Involvement of elevated plasminogen activator inhibitor-1 levels in the pathogenesis of venous leg ulcers has been reported in patients with Klinefelter syndrome. Notably, our patient with 47,XXY/48,XXXY presented with androgen deficiency but normal plasminogen activator inhibitor-1 activity.

    2015-01-01

    Significance: Chronic wounds represent a major burden on global healthcare systems and reduce the quality of life of those affected. Significant advances have been made in our understanding of the biochemistry of wound healing progression. However, knowledge regarding the specific molecular processes influencing chronic wound formation and persistence remains limited. Recent Advances: Generally, healing of acute wounds begins with hemostasis and the deposition of a plasma-derived provisional matrix into the wound. The deposition of plasma matrix proteins is known to occur around the microvasculature of the lower limb as a result of venous insufficiency. This appears to alter limb cutaneous tissue physiology and consequently drives the tissue into a ‘preconditioned’ state that negatively influences the response to wounding. Critical Issues: Processes, such as oxygen and nutrient suppression, edema, inflammatory cell trapping/extravasation, diffuse inflammation, and tissue necrosis are thought to contribute to the advent of a chronic wound. Healing of the wound then becomes difficult in the context of an internally injured limb. Thus, interventions and therapies for promoting healing of the limb is a growing area of interest. For venous ulcers, treatment using compression bandaging encourages venous return and improves healing processes within the limb, critically however, once treatment concludes ulcers often reoccur. Future Directions: Improved understanding of the composition and role of pericapillary matrix deposits in facilitating internal limb injury and subsequent development of chronic wounds will be critical for informing and enhancing current best practice therapies and preventative action in the wound care field.

    To gain insight into the experience of recurrent venous leg ulcers from the individual's perspective and provide knowledge on potential risks of recurrence not previously investigated. Venous leg ulcers are a consequence of chronic venous disease and frequently recur. They are costly and can impact on physical and psychological health. Despite research suggesting the risk can be reduced through compression and lifestyle changes, recurrence rates are often high. This study provides an insight into individual's perceptions of the cause of their ulcers and how they try to avoid them. A qualitative design guided by the Chronic Illness Trajectory Model and Social Cognitive Theory. A purposive sample of three males and four females were recruited from a community nursing clinic.Participants were ulcer free, had experienced at least two previous venous leg ulcers and could speak and comprehend English. An interpretive descriptive approach was taken using semi-structured interviews and thematic analysis. Three themes each containing three categories emerged: The Increasing Influence of the Recurring Wound on Mind and Body, Reflection on Past Experiences and Optimism in the Face of Adversity. Most participants reported traumatic injury and lower leg surgery triggered ulcer recurrence. Failure to replace compression stockings was also deemed a cause. Compression was reported essential but some participants were unaware of the level they were wearing and how often it should be replaced. Other preventive activities included avoiding injury and securing immediate assistance if wounding occurred. Clinicians need to be aware that lower leg surgery may trigger recurrent venous ulceration and that individuals require ongoing emotional, physical and financial support throughout the trajectory of venous disease. The continued use of old compression stockings should be avoided and recurrence prevented by adoption of evidence based practice rather than reflection on past experiences

    Full Text Available OBJECTIVE: to assess the clinical effect of topical treatment using Ulmo honey associated with oral ascorbic acid in patients with venous ulcers. METHOD: longitudinal and descriptive quantitative study. During one year, 18 patients were assessed who were clinically diagnosed with venous ulcer in different stages, male and female, adult, with a mean injury time of 13 months. Ulmo honey was topically applied daily. The dressing was applied in accordance with the technical standard for advanced dressings, combined with the daily oral consumptions of 500 mg of ascorbic acid. The monitoring instrument is the assessment table of venous ulcers. RESULTS: full healing was achieved in 100% of the venous ulcers. No signs of complications were observed, such as allergies or infection. CONCLUSION: the proposed treatment showed excellent clinical results for the healing of venous ulcers. The honey demonstrated debriding and non-adherent properties, was easy to apply and remove and was well accepted by the users. The described results generated a research line on chronic wound treatment.

    2014-09-01

    The aim of this study was to compare venous leg ulcer patients with and without ulcer pain to see whether ulcer pain affected the use of antibiotic treatment and compression therapy throughout healing. A total of 431 patients with venous leg ulcers were included during the study period. Every patient was registered in a national quality registry for patients with hard-to-heal leg, foot, and pressure ulcers. A high incidence of ulcer pain (57%) was found when the patients entered the study. Patients with ulcer pain had been treated more extensively with antibiotics both before and during the study period. Throughout healing there was a significant reduction of antibiotic use among patients in the 'no pain' group, from 44% to 23% (P=0.008). There was no significant difference between the two groups concerning compression therapy (85% vs. 88%), but 12% of patients in the 'pain' group did not get their prescribed compression compared with 6% of patients in the 'no pain' group. The groups did not differ significantly in terms of ulcer duration, ulcer size or healing time. This study shows a high incidence of ulcer pain, confirming that pain has a great impact on patients with venous leg ulcers. Results further suggest that the presence of ulcer pain increases the prescription of antibiotics but does not affect the use of compression therapy. Several advantages were found from using a national quality registry. The registry is a valuable clinical tool showing the importance of accurate diagnosis and effective treatment.

    This trial compared skin blood flow, temperature and incidence of venous leg ulcers in patients with chronic venous disease using compression wraps and elevation pillows. Patients with CEAP C4 skin damage and C5 history of ulcers were randomly assigned to a cryotherapy intervention (n = 138) or placebo cuff control (n = 138) applied to the lower legs over 9 months. The time the ulcers healed prior to enrollment in the study for the cryotherapy group ranged from 1 to 2218 days (n = 8, median = 32 days); for the control group, the range was 24 to 489 days (n = 6, median = 390 days). There were no statistically significant blood flow changes measured in perfusion units with a laser Doppler flowmetre within or between the groups; mean difference between the groups was 0·62, P = 0·619. No differences were noted in skin temperature measured with an infrared thermometer within and between the groups; mean difference between the groups was -0·17°C, P = 0·540. Cryotherapy did not improve skin blood flow or temperature and did not show efficacy in preventing ulcers. However, at least 30% of intervention and 50% of control participants were anticipated to develop an ulcer during the study; only ∼7% occurred. These findings suggest that strict adherence to standard of care decreases the incidence of leg ulcers and remains a best practice for leg ulcer prevention.

    Chronic non-healing venous ulcers are by their very nature colonized with bacteria. The amount and make up will vary based on many variables. The transition from colonization to contamination, critical colonization, and infection complicates the treatment of these ulcers. Silver has been shown to be an effective antimicrobial agent with a diverse antimicrobial footprint, minimal allergic reactions, and has been employed for over twenty-five years with little resistance being encountered. Based on these factors, this study was initiated to evaluate the impact of silver containing absorbent dressings on critically colonized venous leg ulcers.

    Full Text Available The ulcer of the lower extremity is a common chronic disease process in daily practice, in which there is wide variability in treatment. Venous ulcers account for 70% of all vascular ulcers. They occur mainly as there is a valve dysfunction as a result of venous incompetence in the lower limbs. Due to the impact they pose is necessary to apply a corrective treatment and also to demonstrate effectiveness in repairing these ulcers. Our goals are to unify and standardize criteria for action by nursing language records and all perform a standardization of care for these patients. This has been an analysis of the needs of care in patients with ulcers of the lower extremity venous etiology methodology by applying nurse. The patient assessment is made by functional health patterns of M. Gordon, for the diagnosis, interventions and outcome criteria necessary use the NNN taxonomy (NANDA-NIC-NOC. We obtained a total of 3 major diagnostic labels, encoded according to NANDA taxonomy for nursing care quality required 13 interventions. Plant 5 outcome criteria to evaluate the effectiveness and quality of nurse activity. Standardized care plans are a valuable tool. Its use ensures that share a common language, unified performance criteria, achieved quality care for our patients.

    The present review provides an update of the biological profile of Pycnogenol in the light of its use in the treatment of chronic venous insufficiency (CVI) and related venous disorders such as deep vein thrombosis (DVT), post-thrombotic syndrome, long haul air-travel-related leg oedema, venous ulcers and acute haemorrhoids. Pycnogenol is a French maritime pine bark extract produced from the outer bark of Pinus pinaster Ait. subsp. atlantica. Its strong antioxidant, anti-inflammatory and vasodilator activities, antithrombotic effects and collagen stabilizing properties make it uniquely able to target the multi facet pathophysiology of CVI and related venous disorders. Clinical studies have shown that it can reduce oedema of the legs in CVI, reduce the incidence of deep venous thrombosis during long haul flights and enhance the healing of venous ulcers and haemorrhoidal episodes by topical application and/or oral administration. This review highlights clinical research findings on the safety, compliance and efficacy of Pycnogenol, including its use in combination products.

    Full Text Available OBJECTIVE: The aim of this study is to study the response of venous ulcers to compressive therapy plus surgical treatment. STUDY DESIGN : Patients presenting to our hospital from the period March’ 2014 to December’ 2014 with venous ulcers were examined and investigated. Thirty patients who had findings of venous ulcers along with varicose veins were selected for the study. Patients were initially treated with elastic compression bandages to allow ulcer healing followed by surgical intervention of varicose veins and incompetent perforators. The response to treatment was evaluated in terms of symptomatic improvement and ulcer healing. RESULTS: Venous ulcers respond well to both conservative treatment and surgical intervention. Meticulous assessment of patients is necessary for successful treatment. In our study period, elastic compres sion bandages combined with surgical treatment was successful in improving symptoms of venous ulcer as well as ulcer healing in the patients. Patient education regarding compliance to treatment is paramount to ulcer healing and preventing recurrence.

    Executive Summary In April 2008, the Medical Advisory Secretariat began an evidence-based review of the literature concerning pressure ulcers. Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/tech/tech_mn.html to review these titles that are currently available within the Pressure Ulcers series. Pressure ulcer prevention: an evidence based analysis The cost-effectiveness of prevention strategies for pressure ulcers in long-term care homes in Ontario: projections of the Ontario Pressure Ulcer Model (field evaluation) Management of chronic pressure ulcers: an evidence-based analysis Objective The Medical Advisory Secretariat (MAS) conducted a systematic review on interventions used to treat pressure ulcers in order to answer the following questions: Do currently available interventions for the treatment of pressure ulcers increase the healing rate of pressure ulcers compared with standard care, a placebo, or other similar interventions? Within each category of intervention, which one is most effective in promoting the healing of existing pressure ulcers? Background A pressure ulcer is a localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in conjunction with shear and/or friction. Many areas of the body, especially the sacrum and the heel, are prone to the development of pressure ulcers. People with impaired mobility (e.g., stroke or spinal cord injury patients) are most vulnerable to pressure ulcers. Other factors that predispose people to pressure ulcer formation are poor nutrition, poor sensation, urinary and fecal incontinence, and poor overall physical and mental health. The prevalence of pressure ulcers in Ontario has been estimated to range from a median of 22.1% in community settings to a median of 29.9% in nonacute care facilities. Pressure ulcers have been shown to increase the risk of mortality among geriatric patients by

    Pannier, F; Rabe, E

    2013-03-01

    Leg and foot ulcers are symptoms of very different diseases. The aim of this paper is to demonstrate the differential diagnosis of leg ulcers. The majority of leg ulcers occur in the lower leg or foot. In non-venous ulcers the localization in the foot area is more frequent. The most frequent underlying disease is chronic venous disease. In 354 leg ulcers, Koerber found 75.25% venous leg ulcers, 3.66% arterial leg ulcers, 14.66% ulcers of mixed venous and arterial origin and 13.5% vasculitic ulcers. In the Swedish population of Skaraborg, Nelzen found a venous origin in 54% of the ulcer patients. Each leg ulcer needs a clinical and anamnestic evaluation. Duplex ultrasound is the basic diagnostic tool to exclude vascular anomalies especially chronic venous and arterial occlusive disease. Skin biopsies help to find a correct diagnosis in unclear or non-healing cases. In conclusion, chronic venous disease is the most frequent cause of leg ulcerations. Because 25% of the population have varicose veins or other chronic venous disease the coincidence of pathological venous findings and ulceration is very frequent even in non-venous ulcerations. Leg ulcers without the symptoms of chronic venous disease should be considered as non-venous.

    In spite of medical science development and initiation of new technologies in minimally invasive surgery, treatment of advanced chronic venous insufficiency at the 5(th) and 6(th) degree of CEAP classification is still a great clinical challenge. In case of no satisfactory results of non-surgical treatment of recurrent venous ulcers, scientists search for alternative therapeutic methods which could be more effective and lasting. Subfascial endoscopic perforator vein surgery (SEPS) as a method of reducing venous pressure in the superficial venous system could provide healing of the recurrent venous ulcer. In this study we present a review of contemporary opinions about the place and significance of subfascial endoscopic perforator vein surgery as a treatment of advanced chronic venous insufficiency.

    Chronic venous insufficiency of the lower limbs is very prevalent. In recent decades, Doppler ultrasound has become the method of choice to study this condition, and it is considered essential when surgery is indicated. This article aims to establish a method for the examination, including venous mapping and preoperative marking. To this end, we review the venous anatomy of the lower limbs and the pathophysiology of chronic venous insufficiency and explain the basic hemodynamic concepts and the terminology required to elaborate a radiological report that will enable appropriate treatment planning and communication with other specialists. We briefly explain the CHIVA (the acronym for the French term "cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire"=conservative hemodynamic treatment for chronic venous insufficiency) strategy, a minimally invasive surgical strategy that aims to restore correct venous hemodynamics without resecting the saphenous vein.

  15. To what extent might deep venous thrombosis and chronic venous insufficiency share a common etiology?

    Science.gov (United States)

    Malone, P Colm; Agutter, P S

    2009-08-01

    According to the valve cusp hypoxia hypothesis (VCHH), deep venous thrombosis is caused by sustained non-pulsatile (streamline) venous blood flow. This leads to hypoxemia in the valve pockets; hypoxic injury to the inner (parietalis) endothelium of the cusp leaflets activates the elk-1/egr-1 pathway, leading to leukocyte and platelet swarming at the site of injury and, potentially, blood coagulation. Here, we propose an extension of the VCHH to account for chronic venous insufficiency. First, should the foregoing events not proceed to frank thrombogenesis, the valves may nevertheless be chronically injured and become incompetent. Serial incompetence in lower limb valves may then generate ''passive'' venous hypertension. Second, should ostial valve thrombosis obstruct venous return from muscles via tributaries draining into the femoral vein, as Virchow illustrated, ''active'' venous hypertension may supervene: muscle contraction would force the blood in the vessels behind the blocked ostial valves to re-route. Passive or active venous hypertension opposes return flow, leading to luminal hypoxemia and vein wall distension, which in turn may impair vasa venarum perfusion; the resulting mural endothelial hypoxia would lead to leukocyte invasion of the wall and remodelling of the media. We propose that varicose veins result if gross active hypertension stretches the valve ''rings'', rendering attached valves incompetent caudad to obstructed sites, replacing normal centripetal flow in perforating veins with centrifugal flow and over-distending those vessels. We also discuss how hypoxemia-related venous/capillary wall lesions may lead to accumulation of leukocytes, progressive blockage of capillary blood flow, lipodermosclerosis and skin ulceration.

    Full Text Available Aim: The aim was to evaluate the efficacy of platelet-rich plasma (PRP in the treatment of chronic nonhealing ulcers. Methods: A nonrandomized, uncontrolled study was performed on 24 patients with 33 nonhealing ulcers of various etiologies. All patients were treated with PRP at weekly intervals for a maximum of 6 treatments. At the end of the 6-week period, reduction in size of the ulcers (area and volume was assessed. Results: The mean age of the patients was 42.5 years (standard deviation [SD] 12.48. Of 33 ulcers, there were 19 venous ulcers, 7 traumatic ulcers, 2 ulcers secondary to pyoderma gangrenosum, 2 diabetic ulcers, 2 trophic ulcers, and 1 vasculitic ulcer. The mean duration of healing of the ulcers was 5.6 weeks (SD 3.23. The mean percentage of reduction in area and volume of the ulcers was 91.7% (SD 18.4% and 95% (SD 14%, respectively. About 100% resolution in the area was seen in 25 (76% of the ulcers and 100% reduction in volume was seen in 24 (73% of the ulcers at the end of the 6th treatment. Conclusion: Conventional therapies do not provide satisfactory healing for chronic nonhealing ulcers as they are not able to provide the necessary growth factors (GFs (platelet-derived GF, epidermal GF, vascular endothelial GF, etc. which are essential for the healing process.

    Full Text Available Abstract Background Oedema, commonly known as tissue swelling, occurs mainly on the leg and the arm. The condition may be associated with a range of causes such as venous diseases, trauma, infection, joint disease and orthopaedic surgery. Oedema is caused by both lymphatic and chronic venous insufficiency, which leads to pooling of blood and fluid in the extremities. This results in swelling, mild redness and scaling of the skin, all of which can culminate in ulceration. Methods We present a method to model a wide variety of geometries of limbs affected by oedema and venous ulcers. The shape modelling is based on the PDE method where a set of boundary curves are extracted from 3D scan data and are utilised as boundary conditions to solve a PDE, which provides the geometry of an affected limb. For this work we utilise a mixture of fourth order and sixth order PDEs, the solutions of which enable us to obtain a good representative shape of the limb and associated ulcers in question. Results A series of examples are discussed demonstrating the capability of the method to produce good representative shapes of limbs by utilising a series of curves extracted from the scan data. In particular we show how the method could be used to model the shape of an arm and a leg with an associated ulcer. Conclusion We show how PDE based shape modelling techniques can be utilised to generate a variety of limb shapes and associated ulcers by means of a series of curves extracted from scan data. We also discuss how the method could be used to manipulate a generic shape of a limb and an associated wound so that the model could be fine-tuned for a particular patient.

    Scope A systematic review of the clinical literature concerning medical management of chronic venous disease with the venoactive therapy Micronized Purified Flavonoid Fraction was conducted in addition to an investigation of the hemodynamics and mechanism of chronic venous disease. Methods The systematic review of the literature focused on the use of Micronized Purified Flavonoid Fraction (diosmin) which has recently become available in the US, in the management of chronic venous disease. The primary goal was to assess the level of evidence of the role of Micronized Purified Flavonoid Fraction in the healing of ulcers, and secondarily on the improvement of the symptoms of chronic venous disease such as edema. An initial search of Medline, Cochrane Database for Systematic Reviews and Google Scholar databases was conducted. The references of articles obtained in the primary search, including a Cochrane review of phlebotonics for venous insufficiency, were reviewed for additional studies. Studies were included if patients had a diagnosis of chronic venous disease documented with Doppler and Impedance Plethysmography. Studies excluded were those that had patients with arterial insufficiency (Ankle Brachial Index chronic venous disease patients because of its favorable safety profile. The Working Group for chronic venous disease concurs with previous guidance by the International European Society for Vascular Surgery in 2015 which recommended the use of Micronized Purified Flavonoid Fraction for the healing of venous ulcers, alone and adjunctive to compression therapy, and for the reduction in symptoms of chronic venous disease such as edema.

    Full Text Available Chronic venous insufficiency (CVI leads to skin changes with dermal hemosiderin deposition. We studied the presence of hemosiderin in the urine to assess if this could be used as a biochemical marker for CVI. Hereby we present a case control study conducted in a tertiary care centre in South India. There were 100 cases with evidence of advanced CVI (the Clinical-Etiology-Anatomy-Pathophysiology classification: C5, C6 confirmed by duplex scanning. Controls were 50 patients with leg ulcers due to other etiologies. All patients were subjected to urinary hemosiderin testing. In all 100 patients with CVI (C5 and C6 disease axial venous reflux was confirmed by duplex ultrasound. Superficial venous reflux was noted in 71% of patients and deep venous reflux in 54.%. Primary venous insufficiency was the etiology in 81% of patients. Only 4/100 patients had detectable amounts of hemosiderin in the urine. Urine hemosiderin testing to determine presence or absence of CVI yielded the following values: positive predictive value-80%; negative predictive value-33%; sensitivity-4% and specificity-98%. The test could not be recommended as a marker of CVI. In Indian patients urinary hemosiderin is not a useful screening test in CVI.

    The aim of this study was to understand the possible mechanisms by which deep venous insufficiency and venous hypertension are associated with trophic skin changes and ulceration and to explain the therapeutic effect of Pentoxifylline in patients with leg ulcers due to deep venous incompetence. Twenty patients were included in this pilot study. They were graded into two groups: group 1, included 10 patients (5 F and 5 M) with deep venous incompetence and normal arteries; group 2, included 10 patients (1 F and 9 M) with deep venous incompetence and moderate arterial disease. Skin and muscle biopsies were carried out before and after the oral administration of 1,200 mg of Pentoxifylline daily (400 mg t.d.s). The following parameters were investigated by means of light microscopy and immunofluorescence tests: engorgement of venous stroma; decrease of intimal elastica; hyaline degeneration; floccular degeneration; pericapillary fibrin deposits and fibrin degradation products; inflammation and fat necrosis; myofibril degeneration; fibrous scar; regeneration and reconstitution of muscle fibres. The results indicated that local inflammation at the ulcer's area cause accumulation of white blood cells in the capillaries and the interstitial fluid, where there is also accumulation of fibrinogen. These changes may lead to chronic tissue ischaemia and ulceration. The known favourable effect of Pentoxifylline on red cells and leucocyte function as well as its lowering effect on plasma fibrinogen level, may be responsible for the observed therapeutic effect of Pentoxifylline on venous leg ulcers.

    Full Text Available Background: Therapeutic low-frequency ultrasound (US has been used for many years to improve wound healing in chronic wounds like venous leg ulcers. No human data are available for the possible effects of single US applications on microcirculation and their frequency-dependency. Aims: To investigated the role of therapeutic low-frequency US on microcirculation of venous leg ulcers in vivo. Patients and Methods: This is a pilot study on an inpatient basis. We use a newly developed low-frequency continuous-wave US-equipment composed of a US transducer based on piezo-fiber composites that allow the change of frequency. In this study, we apply US of 34 kHz, 53.5 kHz, and 75 kHz respectively. Twelve patients with chronic venous leg ulcers are analyzed. As an adjunct to good ulcer care, therapeutic US is applied, non-contacting, once a day, in a subaqual position for 10 minutes. Microcirculation is assessed in the ulcers adjacent to skin before US-therapy, immediately after the treatment and 30 minutes later. We use a micro-light guide spectrophotometer (O2C, LEA Medizintechnik GmbH, Gieίen, Germany for calculation of blood flow velocity, hemoglobin oxygen saturation (SCO 2 and relative hemoglobin concentration (rHb in 2 and 8 mm depth. Contact-free remission spectroscopy (SkinREM3, Color Control Chemnitz GmbH, Chemnitz, Germany allows contact free measurements in the VIS-NIR range of the spectrum (400 ± 1600 nm. Results: It is seen that therapeutic US is well tolerated. One patient dropped out from a treatment series since he developed erysipelas responding to standard antibiotic. Effects were seen at 34 kHz only. The SO 2 values increased after single US application. The values for rHb were higher in the superficial layer of the wound bed (depth 2 mm compared to deeper parts (8 mm depth. US treatment did not result in significant changes of rHb and blood cell velocity. The data obtained by remission spectroscopy disclose an increase of oxygenized

    Chronic non-healing venous leg ulcers (VLUs) are widespread and debilitating, with high morbidity and associated costs; approximately $15 billion is spent annually on the care of VLUs in the US. Despite this, there is a paucity of treatments for VLUs, due to the lack of pathophysiologic insight into ulcer development as well as the lack of knowledge regarding biologic actions of existing VLU-targeted therapies. The bioengineered bilayered living cellular construct (BLCC) skin substitute is an FDA-approved biologic treatment for healing VLUs. To elucidate the mechanisms through which the BLCC promotes healing of chronic VLUs, we conducted a clinical trial (NCT01327937) in which patients with non-healing VLUs were treated with either standard care (compression therapy) or the BLCC together with standard care. Tissue was collected from the VLU edge before and 1 week after treatment, and samples underwent comprehensive microarray, mRNA, and protein analyses. Ulcers treated with the BLCC skin substitute displayed three distinct transcriptomic patterns, suggesting that BLCC induced a shift from a non-healing to a healing tissue response involving modulation of inflammatory and growth factor signaling, keratinocyte activation, and attenuation of Wnt/β-catenin signaling. In these ways, BLCC application orchestrated a shift from the chronic non-healing ulcer microenvironment to a distinctive healing milieu resembling that of an acute, healing wound. Our findings provide in vivo evidence in patient VLU biopsies of pathways that can be targeted in the design of new therapies to promote healing of chronic VLUs. PMID:28053158

    Leg ulcers are a chronic condition. Healing can be long for venous ulcers and the risk of complications is significant. Infection is the most severe complication and can occur in the form of easily diagnosed acute bacterial dermohypodermitis that generally responds well to antibiotic treatment if given at an appropriate dose or in the form of localized infection that is more difficult to diagnosis. Indeed, no consensus has been reached in the literature on the clinical criteria to retain for the diagnosis of localized infection. Similarly, the most appropriate treatment remains to be established. Local care would be a logical starting point, followed by systemic antibiotics if this approach is unsuccessful. Individual conditions also should be taken into consideration (immunodepression, severe arteriopathy warranting more rapid use of systemic antibiotics). The second most frequent complication is an allergic reaction to a topical agent used for wound care. The rate of sensitivization in patients with leg ulcers is high (60 %), although the rate is declining with modern dressings. No product can be considered perfectly safe for these polysensitized patients. Dermocorticoid therapy can be very effective. Allergology tests are needed. Certain leg ulcers require special care from diagnosis. An arterial origin must be suspected for deep, or necrotic ulcers. Arterial supply must be explored rapidly, followed by a revascularization procedure when necessary. Highly painful superficial extensive necrotic ulcers due to necrotic angiodermitis require hospital care for skin grafts that will control the antiodermitis and provide pain. Carcinoma should be suspected in cases of leg ulcers with an atypical localization exhibiting excessive budding. A biopsy is mandatory for leg ulcers with an unusual course (absence of healing despite well-conducted care).

    The pathogenesis of venous leg ulcers is based on the leakage of fibrinogen leading to a pericapillary fibrin cuff and plugging of capillaries by white blood cells. On the basis of a previous work, we had assumed that the key event in the pathogenesis of venous leg ulcers is related to inflammation generated by activated white blood cells that accumulate under unrelieved blood pressure, because in ulcer biopsies we had detected the presence of tumor necrosis factor-alpha (TNF-alpha) in intracapillary monocytes, elastase in the polymorphonuclear leukocytes near the vessels, and a pericapillary undegraded fibrin cuff causing a diffusion barrier to oxygen. This concept was developed because TNF-alpha synthesized by activated monocytes is responsible for many deleterious effects. It has a potent mitogenic effect on fibroblasts, leading to new collagen deposition and angiogenesis, it induces an increase in collagenase production, it acts through upregulation of an intracellular adhesion molecule (ICAM-1), leading to leukocyte sequestration and consequently a release of toxic metabolites by the polymorphonuclear cells, an early step in chronic inflammation, it activates the coagulation pathway via a marked increase in monocyte-associated tissue factor (TF) procoagulant activity, and it inhibits fibrinolysis by promoting the release of PAI-1, contributing to undegraded fibrin deposition. Therefore, we were interested in evaluating, in patients with venous leg ulcers, the effect of pentoxifylline administered at 1,200 mg daily (versus placebo) for 2-months, as this drug induces a decrease in TNF-alpha synthesis and also blocks its activity. This pilot assay was performed in blind. Evolution of several parameters in ulcer biopsies are analyzed: TNF-alpha, intact fibrin, fibrin degradation products, ICAM-1, TF, and elastase. Pentoxifylline administration induced a decrease of local elastase and of fibrin deposit. These results support the hypothesis that accumulation of

    Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenosies of the internal jugular and/or azygous veins (IJVs-AZ) with opening of collaterals and insufficient drainage proved by reduced cerebral blood flow and increased mean transit time in cerebral MRI perfusional study. The present review is aimed to give a comprehensive overview of the actual status of the art of the diagnosis and treatment of this condition. As far as the origin of venous narrowing is concerned, phlebographic studies of the IJVs and AZ systems demonstrated that venous stenoses were likely to be truncular venous malformations; mostly, they are intraluminal defects such as malformed valve, septa webs. CCSVI condition has been found to be strongly associated with multiple sclerosis (MS), a disabling neurodegenerative and demyelinating disease considered autoimmune in nature. In several epidemiological observations performed at different latitudes on patients with different genetic backgrounds, the prevalence of CCSVI in MS ranges from 56% to 100%. To the contrary, by using venous MR and/or different Doppler protocols, CCSVI was not detected with the same prevalence. Two pilot studies demonstrated the safety and feasibility in Day Surgery of the endovascular treatment of CCSVI by means of balloon angioplasty (PTA). It determines a significant reduction of postoperative venous pressure. Restenosis rate was found out elevated in the IJVs, but negligible in the AZ. However, PTA seems to positively influence clinical and QoL parameters of the associated MS and warrants further randomized control trials.

    Mixed arterial and venous ulcers of the lower limbs are present in around 15-30% of patients with chronic venous ulcers (CVUs) and are considered difficult-to-heal wounds. The aim of this study was to evaluate the results of the treatment of mixed arterial and venous ulcers of the lower limbs with prostaglandin E1 (PGE1) infusion. This study was carried out in 48 consecutive patients. Patients who showed intolerability to PGE1, and patients with peripheral neuropathy, blood or systemic diseases, malignancy and acute wound infections or necrotic tissue on the wound bed were excluded. The patients were separated at random into two main groups: group I (25 patients) received standard treatment and PGE1 infusion. Group II (23 patients) received only standard treatment. Pre-treatment data indicated the area of ulceration. The number of healed ulcers and the variation in the area of ulceration were considered as endpoints. The endpoints were noticed after 120 days from the beginning of treatment. Healing occurred in 80% of limbs of group I and in 52·2% of limbs of group II patients. The average reduction in area was 92% versus 60% in patients of group I and II, respectively. During the whole treatment period, the incidence of adverse events was 8% in group I: there was one case of headache and one case of headache and hypotension combined. No side effects were recorded in patients of group II. In conclusion, PGE1 infusion is a determinant in the reduction of the healing time of mixed ulcers of the lower limbs.

    Venous leg ulcer (VLU) is one of the most common lower extremity ulcerated wound, and is a significant healthcare problem with implications that affect social, economic, and the well-being of a patient. VLU can have debilitating related problems which require weekly medical care and may take months to years to heal. The pathophysiology of VLU is complex, and healing is delayed in many patients due to a persistent inflammatory condition. Patient genetic and environmental factors predispose individuals to chronic venous diseases including VLU. Changes in shear stress affecting the glycocalyx are likely initiating events, leading to activation of adhesion molecules on endothelial cells, and leukocyte activation with attachment and migration into vein wall, microcirculation, and in the interstitial space. Multiple chemokines, cytokines, growth factors, proteases and matrix metalloproteinases are produced. The pathology of VLU involves an imbalance of inflammation, inflammatory modulators, oxidative stress, and proteinase activity. Understanding the cellular and biochemical events that lead to the progression of VLU is critical. With further understanding of inflammatory pathways and potential mechanisms, certain biomarkers could be revealed and studied as both involvement in the pathophysiology of VLU but also as therapeutic targets for VLU healing.

    Full Text Available This review article is concentrating on the news in the pathophysiology of chronic venous insufficiency (CVD. Despite ongoing progress in understanding the molecular aspects of CVD the exact mechanism of its development remains unclear. Many different factors may play role in the pathogenesis of CVD, including changes in hydrostatic pressure, valvular incompetence, increased capillary permeability, endothelial dysfunction, activation of leukocytes, deep venous obstruction, capillary microthrombosis, ineffective function of calf muscle pump, biochemical and structural changes in the vessel wall, extracellular matrix alteration, and several other mechanisms. A better understanding of the pathophysiology is an important step in the finding of new potential treatment.

    Full Text Available Venous ulcers of the lower limbs complicated by infection or chronicity represent a serious public health problem. The elevated number of those afflicted burdens the health services, interferes in quality of life and causes absenteeism. Although there are 2,500 items on the market, ranging from the simplest dressing up to the most complex types of dressing, treatment remains a challenge. Among the substances used, fibrin sealant is the one that promotes diminution of bacterial colonization and of edema, controls hemorrhaging, alters the pain threshold by protecting the nerve endings, hydrates the wound bed and forms granulation tissue that favors healing. Its disadvantages include higher cost and utilization of human fibrinogen that can transmit infectious diseases. The Center for the Study of Venoms and Venomous Animals (CEVAP at São Paulo State University (UNESP developed a new sealant made up of fibrinogen extracted from large animals and from an enzyme obtained from snake venom. The present study, developed in the Health Education Clinic (CEPS of Sacred Heart University (USC aimed to evaluate the effect of the new sealant on the healing process of venous ulcers in 24 adult patients, seven of whom were male and 17 female. Two study groups were formed as follows: Group 1 (G1 - control group of 11 patients treated with essential fatty acid (EFA and Unna's boot, and Group 2 (G2 - 13 patients treated with essential fatty acid (EFA, fibrin sealant and Unna's boot. The follow-up lasted eight weeks and the sealant was applied at only the first and fourth weeks. The results showed that Group 2 presented worse lesion conditions as to healing, but, when comparing the two groups, it was noteworthy that the the sealant was effective in healing venous ulcers. There is evidence that the new sealant is recommended for leg ulcers with the following advantages: ease of application, preparation of the wound bed, diminution of pain and a higher number of

    Full Text Available Metalloproteinases play a role in repair of venous ulcers of the lower limbs. The great majority of studies of metalloproteinase enzyme activity conducted to date have employed material from biopsies of ulcers. We evaluated the viability of using zymography to measure the enzyme activity of metalloproteinases 2 and 9 in samples of venous ulcer exudate collected on swabs. The method chosen for processing the samples proved viable in terms of its ability to provide adequate protein concentrations for analysis. Using zymography, we observed that the parameters that provided the best results for analysis of gelatinolytic activity were 0.125 to 0.5 μg of total protein content in the gels and enzymatic activation time of 19 hours (at 37 °C. Collection of venous ulcer fluid using swabs proved to be a simple, rapid and effective method for obtaining samples for measurement of gelatinolytic activity with a minimum degree of invasivity.

    Although the treatment of venous ulcers requires a set of specific knowledge, non-specialist nurses are unaware of the appropriate therapy, which is a concern in the topical therapy for these skin lesions. This paper aims to present an expert system to support the nursing decision making process in the topical therapy of venous ulcers. It is a development research implemented in five stages: system modeling, knowledge acquisition, knowledge representation from production rules, and system implementation and evaluation. The production rules are presented as well as some cases to simulate the expert system behavior, demonstrating the viability of its usage in nurse's practice. The system may support the decision making about the topical therapy of venous ulcers. However, ulcer evaluation should be correctly made, so that the system provides appropriate suggestions, allowing better organization and planning assistance.

    The aim of this study was to investigate the clinical efficacy of oral Pycnogenol (Horphag Research Ltd, UK) in patients with severe chronic venous insufficiency. Patients with severe venous hypertension (chronic venous insufficiency, ankle swelling) and history of venous ulcerations were treated with Pycnogenol. Patients received oral Pycnogenol (50 mg capsules, 3 times daily for a total of 150 mg daily) for 8 weeks. A group of 21 patients was included in the treatment group and 18 equivalent patients were observed as controls (no treatment during the observation period). All 21 patients (age 53 years; range, 42-60 years; M:F=11:10) in the treatment group completed the 8-week study. Also the 18 controls completed the follow-up period. There were no drop-outs. The average ambulatory venous pressure was 59.3 (SD 7.2; range 50-68) with a refilling time shorter than 10 seconds (average 7.6; SD 3). There were no differences in ambulatory venous pressure or refilling time between the treatment and control patients. The duration of the disease-from the first signs/symptoms-was on average 5.7 years (SD 2.1). At 4 and 8 weeks, in all Pycnogenol-treated subjects, microcirculatory and clinical evaluations indicated a progressive decrease in skin flux, indicating an improvement in the level of microangiopathy; a significant decrease in capillary filtration; a significant improvement in the symptomatic score; and a reduction in edema. There were no visible effects in controls. In conclusion, this study confirms the fast clinical efficacy of Pycnogenol in patients with chronic venous insufficiency and venous microangiopathy. The study indicates the significant clinical role of Pycnogenol in the management, treatment and control of this common clinical problem. The treatment may be also useful to prevent ulcerations by controlling the level of venous microangiopathy.

    Proper level of pressure or compression generated by medical stocking or hosiery is the key element for successful treatment or management of chronic venous disorders such as oedema, leg ulcers, etc. However achieving the recommended compression level and, more importantly, sustaining it using stockings has been a major challenge to the health practitioners supervising the treatment. This work aims to investigate and design a smart compression stocking using shape-memory polymer that allows externally controlling the pressure level in the wrapped position on the leg. Based on thermodynamical rubber theories, we first derived several criteria that have to be satisfied simultaneously in order to achieve the controlled pressure adjustment using external heat stimuli. We then presented a case where such a stocking is developed using a blend yarn consists of selected shape-memory polyurethane and nylon filaments. Extensive experimental work has also been conducted to demonstrate the feasibility and explore the influencing factors involved.

    The Society for Vascular Surgery (SVS) and the American Venous Forum (AVF) published guidelines for the management of venous leg ulcers in August 2014. The goal of this article (Part 2) is to summarize the guidelines that address diagnosis and treatment recommendations published jointly by the SVS and AVF that may affect the nursing practice of vascular nurses. Specific sections include wound evaluation, therapies used on the wound bed itself, compression, and operative or endovascular management. Part 1, published elsewhere in this issue, addressed the epidemiology and financial impact of ulcers, venous anatomy, pathophysiology of venous leg ulcer development, clinical manifestations, and prevention of venous leg ulcers. These 2 parts together provide a comprehensive summary of the joint SVS and AVF guidelines for care of venous leg ulcers.

    2003-01-01

    Chronic venous ulcers are characterized by chronic inflammation. Heme and iron, originating from blood cell hemolysis as well as extravascular necrosis, have been implicated as important pathogenic factors due to their promotion of oxidative stress. It was recently reported that the plasma and tissue protein alpha1-microglobulin is involved in heme metabolism. The protein binds heme, and a carboxy-terminally processed form, truncated alpha1-microglobulin, also degrades heme. Here, we show the...

  8. Chronic Infection and Venous Thromboembolic Disease.

    2015-09-01

    Venous thromboembolic disease often arises as a complication of another pathological condition and/or triggering event. Infectious diseases result from both the direct action of the pathogens themselves and their effect on the immune system. The resulting inflammatory process and the coagulation and fibrinolysis processes share common pathways, explaining why infection is associated with thrombosis. In this brief overview, besides certain chronic infectious diseases, we also consider some acute infections, as the mechanisms are likely to be similar, particularly in the initial infective stage or the more acute episodes of a chronic infection. The infectious agent can be viral, bacterial, fungal, or parasitic. However, the literature on the link between infections and venous thromboembolism (VTE) is uneven, favoring infections that are found in more developed countries where physicians have access to VTE diagnostic tools. Thus, large epidemiological studies in this field are restricted to a limited number of the common chronic infectious diseases such as tuberculosis, while for other infections, particularly parasitic and fungal infections, the link with VTE is only evoked in a few scattered case reports.

    Retrospective analysis of mesoglycan therapeutic activity in venous disorders. The clinical data have been selected from the outpatient database of the Chair of Angiology of the University of Catania (from 1988 to 1997) through a cross survey between the prescription commercial name of mesoglycan and the key words varicose veins, deep venous thrombosis (DVT), chronic venous insufficiency (CVI), post-thrombotic syndrome (PTS), venous thrombosis, venous ulcer. Patients have been selected on the basis of definite data relative to principal diagnosis, clinical history, clinical and instrumental objective phlebological picture, posology and duration of treatment, follow-up visits in the first three years following the first observation. Group 1: 56 patients with first episode DVT; Group 2: 27 patients with recurrent DVT; Group 3: 182 patients with CVI (107 with primitive CVI and 75 with secondary CVI). The selected patients data have been included in new databases. DVT patients were evaluated for recurrence prevalence during the follow-up period (6, 12, 18, 24, 30 and 36 months). In Group 2 the recurrence prevalence in the normal follow-up period was evaluated and, in addition, the clinical chronology of the recurrence previous to observation was drawn, in order to find out the recurrence prevalence of the thrombotic episode preceding our observation. The two prevalence trends ( mesoglycan treatment and episode preceding our observation) have been compared with the Student t test. CVI patients (Group 3) were classified according to CEAP classification criteria. The effectiveness of treatment was assessed according to the changes in the scores of venous dysfunction of CEAP classification (disability score; pain; oedema; skin color change; cutaneous ulcer). The mean and standard deviation of the considered scores have been evaluated with the Student t test comparing each series with the immediately previous series and with the T0 series. The mean dose of mesoglycan was 50

    OBJECTIVE: Activation of proteolytic mechanisms at the cell surface through the activity of urokinase-type plasminogen activator (uPA) bound to its receptor, uPAR, is an important process in wound healing. The soluble forms of uPAR (suPAR and its fragments I, II, and III) have nonproteolytic...... functions that include chemotaxis, adhesion, and proliferation, which also have a role in wound healing. The aim of this study was to determine whether suPAR and its cleaved fragments are present in venous ulcers and whether their levels are associated with healing. METHODS: Ulcer exudates were collected...... from patients with venous leg ulcers (n = 30). Healing was defined as complete re-epithelialization within 6 months of compression therapy. Time-resolved fluorescence immunoassays were validated for quantification of suPAR and its fragments in ulcer exudates. The effect of exudates on keratinocyte...

  11. The controversy on chronic cerebrospinal venous insufficiency

    Full Text Available The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI and its association with both neurodegenerative disorders and multiple sclerosis (MS. We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. Studies of prevalence show a big variability in prevalence of CCSVI in MS patients assessed by established ultrasonographic criteria. This could be related to high operator dependency of ultrasound. However, 12 studies, by the means of more objective catheter venography, show a prevalence >90% of CCSVI in MS. Global hypo-hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Postmortem studies and histology corroborate the 2009 International Union of Phlebology (UIP Consensus decision to insert CCSVI among venous malformations. Finally, safety of balloon angioplasty of the extracranial veins was certainly demonstrated, while prospective data on the potential effectiveness of endovascular treatment of CCSVI support to increase the level of evidence by proceeding with a randomized control trial (RCT. Taking into account the current epidemiological data, including studies on catheter venography, the autoptic findings, and the relationship between CCSVI and both hypo-perfusion and cerebro-spinal fluid flow, we conclude that CCSVI can be definitively inserted among the medical entities. Research is still inconclusive in elucidating the CCSVI role in the pathogenesis of neurological disorders. The controversy between the vascular and the

    Men with and men without a history of peptic ulcers were compared using respiratory symptoms and spirographic measurements taken from data recorded in an epidemiologic study. Among the 1,049 men examined, 7% reported a history of peptic ulcer. A clear relationship appeared between bronchial hypersecretion and peptic ulcers. It persisted after adjustment for age, smoking habits, social class, and country of origin. Men with ulcers inhaled tobacco smoke more often. Ulcers, smoking, and chronic phlegm were independently related to a lower body build index. It seems that the relationship between smoking and ulcers was greater among men with chronic phlegm, and it is postulated that peptic ulcers and "chronic bronchitis" might be related to a "common secretory disorder." After adjustment for age, men with a history of peptic ulcers had, not a lower FEV1, but a higher vital capacity. A slightly lower FEV1/VC ratio cannot in such cases be considered as an index of chronic airflow limitation.

    Evolution and cost of three types of compression therapy (single layer, multilayer and Unna boot) in patients with venous ulceration were compared. The evaluation lasted two months and used photographic records and instrument based on pressure ulcer scale for healing (PUSH). Treatment with monolayer compression therapy presented the lowest cost and more efficacy of the three types, with 82% savings compared with the multilayer therapy. PMID:27579760

    Since systemic treatment of neuropathic plantar ulcers in diabetics (DNPU) has so far been rather ineffective, recent reports of successful management of DNPU by short-term retrograde transvenous leg perfusion (RVP) by South American angiologists encouraged us to apply this treatment method in diabetics suffering from chronic DNPU. Hence, in a prospective comparative clinical trial started in 1989 we have treated 45 male diabetics suffering from DNPU with the same daily doses of netilmycin, administered either in systemic venous infusions (SVI: n = 21, three times/day) or in RVP (n = 24, once/day). After 10 consecutive days of treatment, ulcers had closed in 8 of the 24 patients treated with RVP, as against 3 of the 21 treated with SVI. Diminution of the ulcer area by > 30% including full debridement was achieved in 10/24 of the RVP cases (SVI: 4/21). During 6 months of follow-up, amputation of toes or forefoot was necessary in only 1 patient in the RVP group, but in 4 in the SVI group. Partial restitution of osteolytic damage was observed in some cases after RVP. Our results show that regional netilmycin therapy given by the RVP procedure is clearly superior to equal netilmycin doses administered by SVI for the treatment of DNPU. RVP can be recommended in DNPU, particularly when the ulcers are complicated by infections.

  15. The role of perforators in chronic venous insufficiency.

    2010-02-01

    The treatment of incompetent calf perforating veins (ICPVs) has been ascribed an important role in the therapeutic strategy for reducing superficial venous hypertension in patients with advanced chronic venous insufficiency (C4-C6). Since the open approach to ligation of ICPVs was developed by Linton over 70 years ago, there has been an evolution toward less invasive techniques with lower morbidity. This paper will review the evidence for interruption of ICPVs through a series of systematic analyses of (1) subfascial endoscopic perforating surgery (SEPS) and (2) percutaneous thermal ablation techniques (PAPS). The effectiveness and morbidity of each approach will be discussed as well as the strength of evidence supporting that technique. While there are numerous case series that suggest that SEPS is beneficial for ulcer healing and for the prevention of ulcer recurrence, the sole two RCTs that have compared either open division or SEPS for ICPVs have failed to show a statistical advantage for ICPV ablation. The results of these studies are clouded by the inclusion of patients who received concomitant treatment of their great saphenous vein (GSV). The evidence for PAPS is based on a few (n = 5) case series in peer-reviewed journals, which are limited by small patient populations, limited follow-up, and a focus on surrogate outcomes (occlusion of the perforator) rather than clinical or functional outcomes. Moreover, most of these series were carried out in patients with mild disease. Sclerotherapy of ICPVs, by either liquid or foam, shows promise, but requires greater evidence. Our current approach for limbs with C4-C6 disease is to treat the GSV first and limit treatment of ICPVs to those with high volume flow and large-diameter ICPVs. [corrected

    Venous leg ulcers (VLUs) produce wound fluid (WF), as a result of inflammatory processes within the wound. It is unclear if WF from different healing phases of VLU has a peculiar biochemical profile and how VLU microenvironment affects the wound healing mechanisms. This study was conducted to evaluate the cytokine/chemokine profiles in WF from distinct VLU phases, in WF- and LPS-stimulated monocytes and treated with glycosaminoglycan Sulodexide, a therapeutic option for VLU healing. WF and plasma were collected from patients with VLU during active inflammatory (Infl) and granulating (Gran) phases. Demographics, clinical characteristics and pain measurements were evaluated. WF, plasma, and THP-1 supernatants were analyzed for 27 inflammatory mediators by multiplex immunoassay. Our results demonstrated that: 1) pain was significantly increased in patients with Infl compared to Gran VLU; 2) cytokine profile of Infl WF was found to be statistically different from that Gran WF, as well significantly increased respect to plasma; 3) LPS- and WF-stimulation of THP-1 cells significantly increased the expression of several cytokines compared to untreated cells; 4) Sulodexide treatment of both LPS- and WF-stimulated THP-1 monocytes was able to significantly down-regulate the release of peculiar inflammatory mediators. Our study highlighted the importance to understand biomolecular processes underlying CVI when providing treatment for chronic VLU. Identification of inflammatory biomarkers in leg ulcer microenvironment, may provide useful tools for predicting healing outcome and developing targeted therapies.

    Full Text Available BACKGROUND Venous ulcer is an under-recognized and under-treated disease and it affects quality of life. Chronicity and recurrence is disappointing finding, both for the patient and surgeon. AIM To study any surgically correctable factors in recurrent venous ulcers and clinical implications and to offer solutions that prevent or reduce failure rate of primary surgery in the management of venous ulcers. MATERIALS AND METHODS 12 patients with recurrent venous ulcers following previous procedures for varicose veins were enrolled in this study. Full detailed history, examination and investigations were done. RESULTS Out of 12 patients with recurrent venous ulcers, 10 (83% had undergone saphenofemoral junction ligation and stripping, 2 (16% had undergone laser ablation (Endovenous laser ablation, all had perforator ligation, 7 had undergone split skin grafting with ulcer recurrence, none had Saphenopopliteal junction ligation. When all patients were re-evaluated, we found that 5 patients had incompetent saphenofemoral junction, 2 of them in endovenous laser ablation group; 5 out of 12 had Saphenopopliteal junction incompetency. All 12 patients had incompetent perforators. All 12 of them underwent corrective surgery. All were followed up for 6 months to 36 months (Mean=25.5 months with ulcers showing complete healing with no further evidence of breakdown during follow-up. CONCLUSION Surgery is recommended for venous ulcer patients in all stages. Preventable surgical errors are to be excluded for recurrent venous ulcers. Careful evaluation and accurate preoperative mapping of venous pathology with the help of sonologist experienced in vascular study. Role of surgeon experienced with vascular surgery will prevent failure rate.

    Full Text Available Marian Simka Department of Nursing, College of Applied Sciences, Ruda Slaska, Poland Abstract: This review summarizes the research to date on chronic cerebrospinal venous insufficiency (CCSVI. CCSVI was initially defined as a clinical syndrome comprising stenoses of the internal jugular and/or azygos veins, characterized by collateral venous outflows and reduced cerebral blood flow, and was found primarily in patients with multiple sclerosis. However, the published evidence on CCSVI is very discordant. Catheter venography studies gave a regular picture, with the majority of patients with multiple sclerosis presenting with demonstrable outflow abnormalities in the veins draining the central nervous system. The prevalence of these lesions was over 50%, and even higher (about 90% when more liberal definition of an abnormality or intravascular sonography was used. Further, the results of magnetic resonance venography studies have been quite consistent, in that stenoses of the internal jugular veins have been found in 25%–70% of patients with multiple sclerosis. In contrast, Doppler sonography studies have revealed CCSVI in 0% to 100% of patients. The research is currently suggesting that CCSVI is not a single entity, but rather a group of different anatomic and functional venous abnormalities. Regarding venous outflow from the brain, a patient can present either with diminished inflow to the internal jugular veins resulting from decreased cerebral circulation or with externally compressed or hypoplastic internal jugular veins or stenotic jugular valves. Considering these many faces of CCSVI, it becomes more comprehensible as to why the results of the studies, especially those utilizing Doppler sonography, have been so discordant. Not only were investigators using different diagnostic modalities and distinct protocols, but they were not looking for the same pathology. Since these abnormalities were indeed differently prevalent in patients and

    Martínez Martínez, M L; Escario Travesedo, E; Jiménez Acosta, F

    Chronic venous leg ulcers are a major therapeutic challenge in clinical practice, and the search for new approaches to improve wound healing is essential. Many ulcers do not heal with traditional treatment using compression, debridement, and dressings. Skin-grafts variants, such as pinch grafts, punch grafts, split- or full-thickness skin grafts, and grafts derived from cells cultured in the laboratory, are among the most widely used options in ulcers that do not heal. In recent years, numerous studies have brought to our attention the important role of the hair follicle in the healing process of cutaneous wounds. Putting knowledge into practice, hair follicles from the scalp have been used in punch-type grafts transplanted to the base of chronic ulcers to stimulate healing. Results appear to be better than those with traditional hairless punch grafts, opening new lines of treatment for recalcitrant chronic venous ulcers. Copyright © 2017 AEDV.

    Amongst the various systemic complications of ulcerative colitis, cerebral venous thrombosis (CVT) is an uncommon and serious neurological complication mainly associated during episodes of relapse of ulcerative colitis. CVT is suspected to be a consequence of hypercoagulable state occurring during the disease in genetic predisposed persons. Most patients present with rapid neurological deterioration. This devastating intracranial complication requires immediate medical intervention to avoid potentially life threatening consequences. The outcome is good, provided the disease is diagnosed on time and the treatment is started early. The authors present a patient of CVT, a rare complication seen during relapse of ulcerative colitis.

    Full Text Available Objective: The purpose of this study was to determine the best physical therapy program to increase wound healing rates in patients suffering from venous leg ulcer. Methods: Forty patients who had venous leg ulcer for more than 4 weeks and not respondent well to medical treatment. Patients were classified into 4 equal groups 10 of each, Group (1: received 40 minute of monochromatic infrared energy (MIRE, Group (2: received 40 minutes of exercise program consisted of stretching and resisted exercise (RE, Group (3: received 20 minutes of exercise in addition to 20 minutes of resisted exercise (MIRE/RE, and group (4: control group which received conventional therapy of the ulcer. All groups received treatment 5days per week for 12days. Measurements of ulcer surface area and PUSH scale were conducted before treatment, post 6 days of treatment, and after 12 days of treatment. Results: The one way analysis of variance was used to compare ulcer surface area and PUSH score which revealed that both treatment groups (MIRE and RE had significant (P< 0.05 decrease in ulcer surface area and PUSH scale after 6 and 12days post application of treatment. On the other hand, the combination of MIRE and RE showed a highly significant decrease in ulcer surface area and PUSH score when compared with control or with individual treatment. Conclusion: The results of this study suggest that combination of MIRE to RE is more effective than individual treatment to enhance the healing rate of venous ulcer of the leg.

    Paroxysmal nocturnal hemoglobinuria is an acquired clonal expansion of bone marrow stem cells that are deficient in the decay-accelerating factor, which is a complement regulatory glycoprotein (CD55), as well as in the membrane inhibitor of reactive lysis (CD59) and the C8-binding protein. These proteins are deficient on the membranes of red blood cells, granulocytes, monocytes, and platelets. The disorder is associated with intermittent hemolytic anemia, hemoglobinuria, infection, a tendency toward bone marrow aplasia, and venous thromboses. The thromboses, on resolution, may give rise to endothelial proliferation that may cause ischemia and ulceration, or, alternatively, the thromboses may cause ulceration leading to a granulation tissue response with exaggerated endothelial proliferation. We report a second case of paroxysmal nocturnal hemoglobinuria that presented roentgenographically as an ulcerated circumferential duodenal mass secondary to venous thrombosis accompanied by florid papillary endothelial hyperplasia. We also review the literature concerning this phenomenon.

    ABSTRACT Objective: to compare the measurement area of venous ulcers using AutoCAD(r) and Image Tool software. Method: this was an assessment of reproducibility tests conducted in a angiology clinic of a university hospital. Data were collected from 21 patients with venous ulcers, in the period from March to July of 2015, using a collection form and photograph of wounds. Five nurses (evaluators) of the hospital skin wound study group participated. The wounds were measured using both software programs. Data were analyzed using intraclass correlation coefficient, concordance correlation coefficient and Bland-Altman analysis. The study met the ethical aspects in accordance with current legislation. Results: the size of ulcers varied widely, however, without significant difference between the measurements; an excellent intraclass and concordance correlation was found between both software programs, which seem to be more accurate when measuring a wound area >10 cm². Conclusion: the use of both software programs is appropriate for measurement of venous ulcers, appearing to be more accurate when used to measure a wound area > 10 cm². PMID:27992028

    PurposeDifferent techniques have been described for stenting of venous obstructions. We report our experience with two different confluence stenting techniques to treat chronic bi-iliocaval obstructions.Materials and MethodsBetween 11/2009 and 08/2014 we treated 40 patients for chronic total bi-iliocaval obstructions. Pre-operative magnetic resonance venography showed bilateral extensive post-thrombotic scarring in common and external iliac veins as well as obstruction of the inferior vena cava (IVC). Stenting of the IVC was performed with large self-expandable stents down to the level of the iliocaval confluence. To bridge the confluence, either self-expandable stents were placed inside the IVC stent (24 patients, SECS group) or high radial force balloon-expandable stents were placed at the same level (16 patients, BECS group). In both cases, bilateral iliac extensions were performed using nitinol stents.ResultsRecanalization was achieved for all patients. In 15 (38 %) patients, a hybrid procedure with endophlebectomy and arteriovenous fistula creation needed to be performed because of significant involvement of inflow vessels below the inguinal ligament. Mean follow-up was 443 ± 438 days (range 7–1683 days). For all patients, primary, assisted-primary, and secondary patency rate at 36 months were 70, 73, and 78 %, respectively. Twelve-month patency rates in the SECS group were 85, 85, and 95 % for primary, assisted-primary, and secondary patency. In the BECS group, primary patency was 100 % during a mean follow-up period of 134 ± 118 (range 29–337) days.ConclusionStenting of chronic bi-iliocaval obstruction shows relatively high patency rates at medium follow-up. Short-term patency seems to favor confluence stenting with balloon-expandable stents.

    C. pyloridis colonization was investigated in a selected group of 58 patients with upper gastrointestinal disorders submitted to endoscopy and biopsy. The following results were registered. C. pyloridis was isolated in 14 out of 18 cases of active chronic gastritis, in 15 out of 24 cases of non active chronic gastritis, and 7 out of 8 cases of antral ulceration. A negative finding was registered in 8 patients whose gastric mucosa was normal. Therefore, the Authors consider as valid the etiopathogenetic correlation between C. pyloridis and ulcerative or non-ulcerative chronic gastric diseases, suggested by others.

    Extracorporeal shock waves are defined as a sequence of sonic pulses characterized by high peak pressure over 100 MPa, fast pressure rise, and short lifecycle. In the 1980s extracorporeal shock wave lithotripsy (ESWL) was first used for the treatment of urolithiasis. Orthopedic surgeons use extracorporeal shock wave therapy (ESWT) to treat non-union fractures, tendinopathies and osteonecrosis. The first application of ESWT in dermatology was for recalcitrant skin ulcers. Several studies in the last 10 years have shown that ESWT promotes angiogenesis, increases perfusion in ischemic tissues, decreases inflammation, enhances cell differentiation and accelerates wound healing. We successfully treated a non-healing chronic venous leg ulcer with ESWT. Furthermore we observed an improvement of the lymphatic drainage after application of ESWT. We are confident that ESWT is a non-invasive, practical, safe and efficient physical treatment modality for recalcitrant leg ulcers.

    The paper presents a current understanding of chronic venous insufficiency that develops in venous forms of dysplasia. Management of venous dysplasia must be based on multidisciplinary approach including comprehensive diagnosis (predominantly noninvasive), integrative surgical and non-surgical treatment. Modern therapy must be complex and carried out in highly specialized facilities. Best functional and esthetic results can be achieved only through combined therapy. When surgical or non-surgical interventions are inappropriate or impossible, management focus must be placed on clinical control of vascular anomaly (follow-up and compression-based conservative treatment) aimed at minimization of its unfavorable impact on vital functions and at quality of life improvement.

    This study aims to determine health-related quality of life (HRQoL) in patients suffering with venous ulceration and to correlate wound's severity status with HRQoL loss as well as identify the aspects of HRQoL most negatively affected by the presence of venous ulcers. In this observational, cross-sectional, descriptive, analytical multi-centre study, data was compiled over a period of 3·5 months. Thrity-four patients with venous ulceration were recruited. The RESVECH 2·0 scale was used to monitor wounds. The MAID scale was used to measure wound's severity. The Charing Cross Venous Ulcer Questionnaire (CCVUQe) (Spanish version) was used to evaluate quality of life. The mean CCVUQe score was 60·58 ± 16·04. The HRQoL dimension most affected was 'Emotional state' (mean score = 77. 67 ± 17·34). The average RESVECH 2.0 score for the wounds was 13·15 ± 5·07. A statistically significant association between total CCVUQ-e score and total RESVECH 2.0 score was detected [Pearson correlation coefficient r = 0·546 (P ≤ 0·001)]. Venous ulcers affect patients' HRQoL, particularly their emotional status. There is a relationship between the severity of the wound and loss of HRQoL. The presence of non-viable tissue, poor exudate control and infection all determine loss of HRQoL. New studies are needed to confirm these findings.

    clinical and instrumental diagnosis of mixed ulcer. Results: Fifty-three patients of both sexes were enrolled and divided into two groups by means of randomization tables. Group A (treated group comprised 18 females and ten males (median age: 68.7 years treated with standard treatment (compression therapy and surgery + SDX (600 lipoprotein lipase-releasing units/day intramuscularly for 15 days followed by SDX 250 lipase-releasing units every 12 hours day orally for 6 months as adjunctive treatment. Group B (control group comprised 17 females and eight males (median age: 64.2 years treated with standard treatment only (compression therapy and surgery. The type of surgery was chosen according to anatomical level of vein incompetence: superficial venous open surgery and/or subfascial endoscopic perforating surgery. In all enrolled patients, blood samples were collected in order to evaluate the plasma levels of MMPs and NGAL through enzyme-linked immunosorbent assay. These results were compared to another control group (Group C of healthy individuals. Moreover, biopsies of ulcers were taken to evaluate the tissue expression of MMPs and NGAL through Western blot analysis. Our results revealed that SDX treatment is able to reduce both plasma levels and tissue expression of MMPs improving the clinical conditions in patients with mixed ulcers. Conclusion: Inhibition of MMPs could represent a possible therapeutic intervention to limit the progression of leg ulceration. In particular, our findings demonstrate the efficacy of SDX in patients with mixed arterial and venous chronic ulcers of the lower limbs.

    Full Text Available Objective. To evaluate the effectiveness of external application of traditional Chinese medicine (EA-TCM on venous ulcers. Methods. Seven databases were searched until April 2015 for randomized controlled trials (RCTs of EA-TCM for venous ulcers. Risk of bias was assessed using Cochrane Handbook guidelines. Study outcomes were presented as risk ratios (RRs for dichotomous data or mean differences (MDs for continuous data. Results. Sixteen of 193 potentially relevant trials met the inclusion criteria; however, their methodological qualities were low. Comparison of the same intervention strategies revealed significant differences in total effectiveness rates between EA-TCM and conventional therapy groups (RR = 1.22, 95% confidence interval [CI] = 1.16–1.29, and P<0.00001. Compared to conventional therapy, EA-TCM combined with conventional therapy had a superior total effectiveness rate (RR = 1.11, 95% CI = 1.04–1.19, and P=0.003. There were no significant differences in recurrence rates during followup and final pain measurements between the experimental and those in the control groups (RR = 0.86, 95% CI = 0.31–2.39, and P=0.85; MD −0.75, 95% CI = −2.15–0.65, and P=0.29. Conclusion. The evidence that EA-TCM is an effective treatment for venous ulcers is encouraging, but not conclusive due to the low methodological quality of the RCTs. Therefore, more high-quality RCTs with larger sample sizes are required.

    The Society for Vascular Surgery (SVS) and the American Venous Forum (AVF) have developed clinical practice guidelines for the care of patients with varicose veins of the lower limbs and pelvis. The document also includes recommendations on the management of superficial and perforating vein incompetence in patients with associated, more advanced chronic venous diseases (CVDs), including edema, skin changes, or venous ulcers. Recommendations of the Venous Guideline Committee are based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system as strong (GRADE 1) if the benefits clearly outweigh the risks, burden, and costs. The suggestions are weak (GRADE 2) if the benefits are closely balanced with risks and burden. The level of available evidence to support the evaluation or treatment can be of high (A), medium (B), or low or very low (C) quality. The key recommendations of these guidelines are: We recommend that in patients with varicose veins or more severe CVD, a complete history and detailed physical examination are complemented by duplex ultrasound scanning of the deep and superficial veins (GRADE 1A). We recommend that the CEAP classification is used for patients with CVD (GRADE 1A) and that the revised Venous Clinical Severity Score is used to assess treatment outcome (GRADE 1B). We suggest compression therapy for patients with symptomatic varicose veins (GRADE 2C) but recommend against compression therapy as the primary treatment if the patient is a candidate for saphenous vein ablation (GRADE 1B). We recommend compression therapy as the primary treatment to aid healing of venous ulceration (GRADE 1B). To decrease the recurrence of venous ulcers, we recommend ablation of the incompetent superficial veins in addition to compression therapy (GRADE 1A). For treatment of the incompetent great saphenous vein (GSV), we recommend endovenous thermal ablation (radiofrequency or laser) rather than high ligation and inversion stripping

    Retrograde venous perfusions (RVP) of antibiotics were proven to be therapeutically more effective than systemic venous infusions (SVI) in patients with infected diabetic neuropathic plantar ulcers (DNPU: no additional macronagiopathy of leg arteries). In order to study some pharmakokinetic features of RVP application paratibial tissue levels of Netilmycin (NL; from suction blister fluid) and cubital venous NL were compared under each SVI and RVP therapy in 8 patients with DNPU. Tissue (11.6 +/- 6.4 micrograms/l) were significantly higher (p ulcer transsudate (RVP only; n = 4) NL mounted to 36.4 +/- 11.6 microgram/ml. Peak and base NL in cubital blood were within the normal range for both SVI and RVP (no significant difference). The date indicate that RVP is superior to SVI application of Netilmycin (and probably other antibiotics) as surmounting the damaged microcirculation in DNPU to achieve effective drug levels in the target tissue.

    The variation in the management of venous leg ulceration in the UK is partly attributable to an uncertain clinical environment but the quality of judgements is influenced by the how well nurses' confidence and accuracy are aligned. To assess UK community nurses' confidence in the accuracy of their diagnostic judgements and treatment choices when managing venous leg ulceration. Judgement Analysis. UK community and primary care nursing services. 18 community non-specialist nurses working in district (home) nursing teams and general practitioner services and 18 community tissue viability specialist nurses. Using judgement analysis methods, 18 community non-specialist nurses and 18 community tissue viability specialist nurses made diagnoses and treatment judgements about compression therapy for 110 clinical scenarios and indicated their confidence for each judgement. An expert panel made consensus judgements for the same scenarios and these judgements were used as a standard against which to compare the participants. Confidence analysis was used to assess the nurses' confidence about their diagnostic judgements and treatment choices. Despite being very experienced, both non-specialist nurses' and specialist tissue viability nurses' levels of confidence were not well calibrated with their levels of accuracy. The results of this study are important as errors resulting from both over and under-confidence at the diagnostic phase of management may influence treatment choices, and thus increase the chances of treatment error.

  8. The incidence of postoperative venous thrombosis among patients with ulcerative colitis.

    LENUS (Irish Health Repository)

    O'Connor, O J

    2012-02-03

    BACKGROUND: Patients with Ulcerative Colitis (UC) have inherent prothrombotic tendencies. It is unknown whether this necessitates the use of additional perioperative anti-thrombotic prophylaxis when such patients require major surgery. METHODS: The postoperative courses of 79 patients with UC undergoing 180 major abdominal and pelvic operations were examined for clinical and radiological evidence of venous thrombosis. Eighteen patients with Familial Adenomatous Polyposis (FAP) having surgery (35 operations) of similar magnitude were also studied. Standard anti-thrombosis prophylaxis was utilised in all patients. RESULTS: Nine patients with UC were clinically suspected of developing postoperative venous thrombosis, but only three (3.8%) had their diagnosis confirmed radiologically (all had a pulmonary embolus). Therefore, the overall postoperative thrombosis rate, on an intention to treat basis, was 1.7% (3\\/180). No patient with FAP developed significant venous thrombosis. CONCLUSION: Standard perioperative antithrombotic modalities are sufficient to maintain any potential increase in postoperative thrombotic risk at an acceptable level in patients with UC undergoing operative intervention.

    Venous leg ulceration has a high recurrence rate. Patients with healed or frequently recurring venous ulceration are required to perform self-care behaviours to prevent recurrence or promote healing, but evidence suggests that many find these difficult to perform. Bandura's self-efficacy theory is a widely used and robust behaviour change model and underpins many interventions designed to promote self-care in a variety of chronic conditions. By identifying areas where patients may experience difficulty in performing self-care, interventions can be developed to strengthen their self-efficacy beliefs in performing these activities successfully. There are currently a variety of self-efficacy scales available to measure self-efficacy in a variety of conditions; but not a disease-specific scale for use with venous ulcer patients. The aim of this study, therefore, was to develop and validate a disease-specific, patient-focused self-efficacy scale for patients with healed venous leg ulceration. This scale will need further validation studies; however, it is ready for use in clinical practice and will enable practitioners to identify those patients who may need additional support in performing self-care activities to prevent recurrence.

    Primary care databases from the UK have been widely used to produce evidence on the epidemiology and health service usage of a wide range of conditions. To date there have been few evaluations of the comparability of estimates between different sources of these data. To estimate the comparability of two widely used primary care databases, the Health Improvement Network Database (THIN) and the General Practice Research Database (GPRD) using venous leg ulceration as an exemplar condition. Cross prospective cohort comparison. GPRD and the THIN databases using data from 1998 to 2006. A data set was extracted from both databases containing all cases of persons aged 20 years or greater with a database diagnosis of venous leg ulceration recorded in the databases for the period 1998-2006. Annual rates of incidence and prevalence of venous leg ulceration were calculated within each database and standardized to the European standard population and compared using standardized rate ratios. Comparable estimates of venous leg ulcer incidence from the GPRD and THIN databases could be obtained using data from 2000 to 2006 and of prevalence using data from 2001 to 2006. Recent data collected by these two databases are more likely to produce comparable results of the burden venous leg ulceration. These results require confirmation in other disease areas to enable researchers to have confidence in the comparability of findings from these two widely used primary care research resources. © The Author 2015.

    Venous leg ulcers constitute a chronic recurring complaint that affects 1.0-1.3% of the adult population at some time in life, and which corresponds to approximately 75% of all chronic ulcers of the leg. Multilayer compression bandaging is, at present, the only treatment that has been proved to be effective in treating this type of ulcer. There is no consensus, however, about the dressings that may be applied, beneath the compression, to promote the healing of this type of ulcer, as there does not seem to be any added benefit from using special dressings rather than simple, low-adherence ones. As well as analgesia, acupuncture provokes peripheral vasodilation, in skin and muscles - which has been demonstrated both experimentally and in clinical practice - probably due to the axon reflex, among other mechanisms. The aim of the present study is to measure the effectiveness and cost of compression treatment for venous leg ulcers combined with special dressings, in comparison with low-adherence ones and acupuncture. Cluster-randomized open-labeled trial, at 15 primary healthcare clinics in the Sevilla-Sur Healthcare District, with a control group treated with compression bandaging and low-adherence dressings; the experiment will consist, on the one hand, of the compression treatment applied in combination with special dressings (Treatment 1), and on the other, the compression treatment applied in association with low-adherence dressings, together with acupuncture (Treatment 2). The results will be measured and recorded in terms of the median time elapsed until complete healing of the ulcer, and the rate of complete healing at 3 months after beginning the treatment. An economic analysis will also be made. This study, carried out in the context of real clinical practice, will provide information for decision-taking concerning the effectiveness of special dressings. Moreover, for the first time a high-quality study will evaluate the effectiveness of acupuncture in the

    Gout is the most common form of inflammatory arthritis and it has an affliction to the foot. Foot involvement in gout has been linked to foot pain, impairment and disability. There has been limited research on the effect of ulceration on foot pain, impairment, disability and health-related quality of life in patients already living with gout. The aim of the study was to describe the wound characteristics and the effect on foot pain, disability and health-related quality of life in patients with foot ulceration associated with gout. Participants were recruited from rheumatology clinics in Auckland, New Zealand. All the current foot ulceration sites and wound characteristics were recorded using the TIME wound assessment tool. The outcome measures included general pain, patient global assessment scale, foot pain, disability and impairment. Participants completed the Cardiff Wound Impact Schedule to assess the effect of ulcers on health-related quality of life. Sensory loss, vibrational thresholds and ankle brachial pressure index were collated to assess for lower limb arterial disease. Six participants were predominantly older men with a long duration of gout, high rates of obesity and co-morbidities such as hypertension, hyperlipidaemia, diabetes and cardiovascular disease. The mean (SD) duration of the foot ulcers was 4 (2) months. The majority of foot ulcers observed were 0·5 cm(2) or smaller superficial thickness with surrounding callus. Partial thickness and full-thickness ulcers were also observed. Two patients presented with ulcers on multiple sites. There was only one case of infection. Gouty tophi were evident in most of the wounds. The dorsal aspect of the third toe was found to ulcerate in most cases. Moderate scores of foot pain, disability, impairment and health-related quality of life were observed. Most participants wore shoes deemed as poor. Foot ulceration in gout is chronic and multiple ulcers can occur with the potential of leading to delayed

    To compare data on time to healing from two separate cohorts: one treated with a new acellular synthetic matrix plus standard care (SC) and one matched from four large UK pragmatic, randomised controlled trials [venous leg ulcer (VLU) evidence network]. We introduce a new proof-of-concept strategy to a VLU clinical evidence network, propensity score matching and sensitivity analysis to predict the feasibility of the new acellular synthetic matrix plus SC for success in future randomised, controlled clinical trials. Prospective data on chronic VLUs from a safety and effectiveness study on an acellular synthetic matrix conducted in one wound centre in the UK (17 patients) and three wound centres in Australia (36 patients) were compared retrospectively to propensity score-matched data from patients with comparable leg ulcer disease aetiology, age, baseline ulcer area, ulcer duration, multi-layer compression bandaging and majority of care completed in specialist wound centres (average of 1 visit per week), with the outcome measures at comparable follow-up periods from patients enrolled in four prospective, multicentre, pragmatic, randomised studies of venous ulcers in the UK (the comparison group; VLU evidence network). Analysis using Kaplan-Meier survival curves showed a mean healing time of 73·1 days for ASM plus SC (ASM) treated ulcers in comparison with 83·5 days for comparison group ulcers treated with SC alone (Log rank test, χ(2) 5·779, P = 0·016) within 12 weeks. Sensitivity analysis indicates that an unobserved covariate would have to change the odds of healing for SC by a factor of 1·1 to impact the baseline results. Results from this study predict a significant effect on healing time when using a new ASM as an adjunct to SC in the treatment of non-healing venous ulcers in the UK, but results are sensitive to unobserved covariates that may be important in healing time comparison. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    To assess the relationship between sex, age, geographical region, lower limb symptoms and the presence of trunk varicose veins and venous incompetence. Cross-sectional population study in 24 cities in the North, centre and South of Italy. Five thousand two hundred and forty-seven people were selected during spring and summer 2003 by advertising on television, in newspapers, and by leaflets in 24 Italian cities. In all 5187 (4457 [85.9%] women and 730 men [14.1%]) volunteers were assessed. The median age was 54 (range: 18-90) years for the women and 61 (range: 18-89) years for the men. Self-administered questionnaire on subjective symptoms of chronic venous insufficiency (CVI) in the lower limbs, and clinical examination, including colour duplex ultrasonography to assess the presence and severity of varicose veins. Overall only 22.7% of the subjects examined were free of visible signs of venous disease, with approximately 53% of the population over 50 years of age showing some venous reflux. People living in Southern Italy were more severely affected than those living in the North. Varicosities and telangiectases were the most frequent objective signs in both sexes. Trunk varicosities (27%) and saphenous reflux (41%) increased with age and were more common in men; in contrast, minor objective symptoms such as telangiectases (70%), as well as subjective symptoms such as heavy (79%) and tired legs (78%), were more common in women and were not age-related. Venous disease is very common in Italy, in particular in people living in the South. A correlation between varicose veins and venous incompetence is more marked in men, while minor objective and subjective symptoms prevail in women. The findings from this non-random sample closely match results from previous studies, in which random sampling was used.

    Full Text Available Abstract Background Tissue engineering is an emerging field. Novel bioengineered skin substitutes and genetically derived growth factors offer innovative approaches to reduce the burden of diabetic foot and venous leg ulcers for both patients and health care systems. However, they frequently are very costly. Based on a systematic review of the literature, this study assesses the cost-effectiveness of these growth factors and tissue-engineered artificial skin for treating chronic wounds. Methods On the basis of an extensive explorative search, an appropriate algorithm for a systematic database search was developed. The following databases were searched: BIOSIS Previews, CRD databases, Cochrane Library, EconLit, Embase, Medline, and Web of Science. Only completed and published trial- or model-based studies which contained a full economic evaluation of growth factors and bioengineered skin substitutes for the treatment of chronic wounds were included. Two reviewers independently undertook the assessment of study quality. The relevant studies were assessed by a modified version of the Consensus on Health Economic Criteria (CHEC list and a published checklist for evaluating model-based economic evaluations. Results Eleven health economic evaluations were included. Three biotechnology products were identified for which topical growth factors or bioengineered skin substitutes for the treatment of chronic leg ulceration were economically assessed: (1 Apligraf®, a bilayered living human skin equivalent indicated for the treatment of diabetic foot and venous leg ulcers (five studies; (2 Dermagraft®, a human fibroblast-derived dermal substitute, which is indicated only for use in the treatment of full-thickness diabetic foot ulcers (one study; (3 REGRANEX® Gel, a human platelet-derived growth factor for the treatment of deep neuropathic diabetic foot ulcers (five studies.

    Compression is an effective and recommended treatment for venous leg ulcers. Although the four-layer bandage (4LB) is regarded as the gold standard compression system, it is recognised that the amount of compression delivered might be compromised by poor application technique. Also the bulky nature of the bandages might reduce ankle or leg mobility and make the wearing of shoes difficult. Two-layer compression hosiery systems are now available for the treatment of venous leg ulcers. Two-layer hosiery (HH) may be advantageous, as it has reduced bulk, which might enhance ankle or leg mobility and patient adherence. Some patients can also remove and reapply two-layer hosiery, which may encourage self-management and could reduce costs. However, little robust evidence exists about the effectiveness of two-layer hosiery for ulcer healing and no previous trials have compared two-layer hosiery delivering 'high' compression with the 4LB. Part I To compare the clinical effectiveness and cost-effectiveness of HH and 4LB in terms of time to complete healing of venous leg ulcers. Part II To synthesise the relative effectiveness evidence (for ulcer healing) of high-compression treatments for venous leg ulcers using a mixed-treatment comparison (MTC).

    Chronic cerebrospinal venous insufficiency (CCSVI) represents a recently described condition that may potentially contribute to the symptoms experienced by patients with multiple sclerosis. The evaluation of a prospective patient for CCSVI often involves an invasive evaluation with venography of the internal jugular and azygos veins. The purpose of this article is to review the normal anatomy of the internal jugular, vertebral, and azygos veins, as an understanding of these veins is necessary for appropriate interpretation of the venograms obtained to evaluate patients for CCSVI.

    Full Text Available Water-insoluble glucan was isolated from the baker’s yeast Saccharomyces cerevisiae. The yeast cells were treated with alkali and the residue then with acid. Chemical and NMR (1D and 2D analyses showed that a linear (1→3-β-glucan was purified that was not contaminated with other carbohydrates, proteins or phenolic compounds. The effects of the glucan on wound healing were assessed in human venous ulcers by histopathological analysis after 30 days of topical treatment. (1→3-β-glucan enhanced ulcer healing and increased epithelial hyperplasia, as well as increased inflammatory cells, angiogenesis and fibroblast proliferation. In one patient who had an ulcer that would not heal for over 15 years, glucan treatment caused a 67.8% decrease in the area of the ulcer. This is the first study to investigate the effects of (1→3-β-glucan on venous ulcer healing in humans; our findings suggest that this glucan is a potential natural biological response modifier in wound healing.

In the blinded Combined Transcranial (TCD and Extracranial Venous Doppler Evaluation (CTEVD study, we found that prevalence of CCSVI was significantly higher in multiple sclerosis (MS vs. healthy controls (HC (56.1% vs. 22.7%, p  The objective was to evaluate the clinical correlates of venous anomalies indicative of CCSVI in patients with MS. Methods The original study enrolled 499 subjects; 163 HC, 289 MS, 21 CIS and 26 subjects with other neurological disorders who underwent a clinical examination and a combined Doppler and TCD scan of the head and neck. This analysis was restricted to adult subjects with MS (RR-MS: n = 181, SP-MS: n = 80 and PP-MS: n = 12. Disability status was evaluated by using the Kurtzke Expanded Disability Status Scale (EDSS and MS severity scale (MSSS. Results Disability was not associated with the presence (≥2 venous hemodynamic criteria or the severity of CCSVI, as measured with venous hemodynamic insufficiency severity score (VHISS. However, the severity of CCSVI was associated with the increased brainstem functional EDSS sub-score (p = 0.002. In logistic regression analysis, progressive MS (SP-MS or PP-MS vs. non-progressive status (including RR-MS was associated with CCSVI diagnosis (p = 0.004, OR = 2.34, CI = 1.3–4.2. Conclusions The presence and severity of CCVSI in multiple sclerosis correlate with disease status but has no or very limited association with clinical disability.

    to evaluate pain in patients with lower limb venous ulcer who used non-adherent Ibuprofen foam dressing (IFD). we conducted a prospective study of patients with lower limb venous ulcers treated from April 2013 to August 2014. We used the Numerical Scale and McGill Pain Questionnaire, performing the assessments at the moment of inclusion of the patient in the study and every eight days thereafter, totaling five consultations. We divided the patients into two groups: 40 in the Study Group (SG), who were treated with IFD, and 40 in the Control Group (CG), treated with primary dressing, according to tissue type and exudate. at the first consultation, patients from both groups reported intense pain. On the fifth day, SG patients reported no pain and the majority of CG reported moderate pain. Regarding the McGill Pain Questionnaire, most patients of both groups reported sensations related to sensory, affective, evaluative and miscellaneous descriptors at the beginning of data collection; after the second assessment, there was slight improvement among the patients in the SG. After the third consultation, they no longer reported the mentioned descriptors. CG patients displayed all the sensations of these descriptors until the fifth visit. non-adherent Ibuprofen foam dressing is effective in reducing the pain of patients with venous ulcers. avaliar a dor em pacientes portadores de úlcera venosa de membros inferiores que utilizaram curativo de espuma não aderente com Ibuprofeno (CEI). estudo prospectivo de pacientes portadores de úlceras venosas de membros inferiores tratados no período de abril de 2013 a agosto de 2014.

    Full Text Available Herpes simplex virus infections in HIV-infected individuals can be clinically unusual and difficult to treat due to underlying problems with cell-mediated immunity and the occurrence of antiviral resistance. Additionally, partial or incomplete restoration of immune function may result in chronic ulcerations that require rotational treatments. In this report, we describe the case of a 38-year-old HIV-positive woman who developed the ulcerative form of chronic herpes simplex infection despite highly active antiretroviral therapy and valacyclovir prophylaxis. Repeated intravenous courses of foscarnet and topical cidofovir finally controlled her erosions as her cell-mediated immunity was slowly restored. This case highlights the challenges that still exist in diagnosing and managing this rare presentation of herpes simplex virus

    To assess the impact of a two-period treatment on the clinical condition, bacteriological changes and results of treatment of venous leg ulcers (VLU) using octenidine dihydrochloride. Patients with a VLU were recruited and treated with octenidine dihydrochloride for one month, after which they were randomised and treated with hydrocolloids or foam dressings. The wounds were clinically assessed for the amount of necrotic tissue, granulation tissue, epithelialisation, amount of exudate and pain level. During the first period, bacterial colonisation and antimicrobial efficacy of octenidine dihydrochloride were also evaluated. In the second period the efficacy of treatment, time of treatment and healing rate were investigated. In the group of 50 VLU patients, all wounds (100%) improved after the first treatment period. No clinical signs of infection were observed. Statistically significant changes were observed in all the clinical parameters studied in the treated groups of VLU patients, including reduction of necrotic tissue, the amount of exudate and of pain, as well as increased granulation and epithelialisation. In the second period including treatment with the two dressings, no differences were observed in treatment efficacy, time of treatment or healing rate. As used in this study, octenidine dihydrochloride proved to be effective and useful, changing the clinical condition of VLU, preparing the wound for future treatment with modern dressings. High microbicidal activity of octenidine was observed, both against Gram-negative and Gram-positive bacteria isolated from the ulcers. Octenidine dihydrochloride caused an eradication of multiresistant strains (88%) as well as of bacteria qualified as alert-pathogens (100%) in the treated wounds after four weeks. However, no differences in the effects, time or rate of healing of VLU with two dressings were found in the second period. No side effects or significant local intolerance reactions used for treatment were

    Multiple sclerosis (MS) is a disorder characterized by damage to the myelin sheath insulation of nerve cells of the brain and spinal cord affecting nerve impulses which can lead to numerous physical and cognitive disabilities. The disease, which affects over 500,000 people in the United States alone, is widely believed to be an autoimmune condition potentially triggered by an antecedant event such as a viral infection, environmental factors, a genetic defect or a combination of each. Chronic cerebrospinal venous insufficiency (CCSVI) is a condition characterized by abnormal venous drainage from the central nervous system that has been theorized to have a possible role in the pathogenesis and symptomatology of MS (1). A significant amount of attention has been given to this theory as a possible explanation for the etiology of symptoms related to MS patients suffering from this disease. The work of Dr. Zamboni, et al, who reported that treating the venous stenoses causing CCSVI with angioplasty resulting in significant improvement in the symptoms and quality of life of patients with MS (2) has led to further interest in this theory and potential treatment. The article presented describes endovascular techniques employed to diagnose and treat patients with MS and CCSVI.

    To assess self-esteem in patients with venous leg ulcers treated with Unna's boot. • A descriptive, analytic, clinical study was conducted from June 2010 to May 2011 in an outpatient wound care clinic in São Paulo, Brazil. Patients of both sexes, aged ≥18 years, who had had a venous leg ulcer for more than one year and a Doppler ankle brachial index ranging from 0.8-1.0 were consecutively selected for inclusion. Patients were treated with wound dressings and Unna's boot. Self-esteem was assessed using the Brazilian version of the Rosenberg Self-Esteem Scale (RSE) at inclusion (baseline) and after 4, 8, and 12 months of compression therapy using Unna's boot. The scale is reverse-scored; thus lower scores indicate higher levels of self-esteem. • The patients showed a slight but significant improvement in self-esteem after 4 months of treatment (mean RSE score=17.12) compared with baseline (mean RSE score=24.90). However, a marked and significant improvement in self-esteem was observed after 8 months (mean RSE score=7.40) and 12 months (mean RSE score=2.10) of compression therapy using Unna's boot. • Patients with venous leg ulcers treated with Unna's boot for 12 months showed a significant improvement in self-esteem • All authors declare that no competing financial interests exist. There was no external funding for this study.

De todos los métodos de control de la HTV, el sistema multicapa ha demostrado clínicamente que permite alcanzar un 80% de tasa de cicatrización de lesiones a las doce semanas de tratamiento, erigiéndose como el tratamiento más efectivo de los existentes hasta el momento. Por otro lado, a menudo, una compresión de 40 mm Hg en el tobillo no es bien tolerada por todas las personas afectadas de HTV crónica. Para esos casos rebeldes en los que debemos utilizar recursos alternativos, nosotros hemos utilizado la cromoterapia ya que ha demostrado, mediante varios estudios, ser útil en la curación de heridas consiguiendo, entre otros beneficios, estimular el aporte sanguíneo al lecho de la herida, favoreciendo así la oxigenación. En base a estos hechos, nos planteamos la aplicabilidad de la cromoterapia en la cura de las úlceras venosas, como tratamiento complementario a las curas habituales, cuando estos no son lo suficientemente efectivos o cuando el paciente no tolera el vendaje elástico multicapa.Venous ulcers are the most prevalent ulcers of the lower extremity. They account for 75%-80% of ulcers of the lower extremity. According to the evidence available, there are two main strands to therapy: treatment of the ulcer as a chronic wound, and management of venous hypertension (VHT, the prime cause of venous ulcers. VHT is managed using decreasing and sustained high-compression systems. According to the literature, the multilayer system has been

    Several small studies have indicated that the systemic administration of pentoxifylline may accelerate healing of venous leg ulcers. The goal of this study was to further evaluate these findings in a larger scale placebo controlled trial and to explore the effect of the dose of pentoxifylline on healing. The study used a prospective, randomized, double-blind, parallel group placebo controlled design in a multicenter outpatient setting. Patients with one or more venous ulcer were enrolled, with all patients receiving standardized compression bandaging for treatment for their ulcers. Patients were also randomized to receive either pentoxifylline 400 mg, pentoxifylline 800 mg (two 400 mg tablets), or placebo tablets three times a day for up to 24 weeks. The main outcome measure was time to complete healing of all leg ulcers, using life table analysis. The study was completed as planned in 131 patients. Patients receiving 800 mg three times a day of pentoxifylline healed faster than placebo (p = 0.043, Wilcoxon test). The median time to complete healing was 100, 83, and 71 days for placebo, pentoxifylline 400 mg, and pentoxifylline 800 mg three times a day, respectively. Over half of all patients were ulcer free at week 16 (placebo) and at week 12 in both pentoxifylline groups. Whereas the placebo group had only achieved complete healing in half of the cases by week 16, all of the subjects remaining in the group receiving the high dose of pentoxifylline had healed completely. Treatment with pentoxifylline was well tolerated with similar drop-out rates in all three treatment groups. Complete wound closure occurred at least 4 weeks earlier in the majority of patients treated with pentoxifylline by comparison to placebo. A higher dose of pentoxifylline (800 mg three times a day) was more effective than the lower dose. We conclude that pentoxifylline is effective in accelerating healing of leg ulcers.

    Full Text Available Diabetic ulcers and pressure ulcers represent a more frequent cause of chronic wounds in aging populations. It is estimated that approximately 15% of the diabetic population will develop diabetic ulcers during their life and over half of these patients develop an infection, often osteomyelitis, with 20% requiring amputation. The authors report a case of a 65-year-old woman affected by a post-traumatic loss of substance due to road accidents with soft tissue exposure (comprising muscle tendon of the left knee combined with the fracture of the right fibula previously subjected to surgery and reconstruction of muscle tendon. The patient was affected by diabetes type II, hypertension, and ischemic heart disease. In 2008, she underwent a double bypass surgery and coronary angioplasty. Initially, the patient was treated with cycles of advanced dressings, with fibrinolytic ointments, hydrocolloid, and subsequently, when the bottom began granulated with fibrinolytic and idrocellulosa, Hydrofibra-Ag, and Ag-alginate, three times a week for 30 days. In the second step, the authors decided to treat the ulcer with the MATRIDERM system and auto skin graft. Following the first treatment, 7 days after the procedure, the authors found the reduction of the loss of substance until its complete closure. The wound’s infection was evaluated by a buffer negative confirmation performed every 2 weeks four times. We obtained decrease of limb edema and full functional rehabilitation. The skin appeared renovated, with volume restoration and an improvement of the texture.

    Full Text Available There has been limited examination of the contribution of socio-economic factors to the development of leg ulcers, despite the social patterning of many underlying risk factors. No previous studies were found that examined social patterns in the quality of treatment received by patients with leg ulcers.Using The Health Improvement Network (THIN database we identified a cohort of over 14000 patients with a diagnosis of venous leg ulceration, prospectively recorded between the years 2001 and 2006, with linked area-level socio-economic information (Townsend deprivation quintile. We assessed socio-economic differences in the incidence and prevalence of leg ulcers using negative binomial regression. Socio-economic differences in two key areas of guideline recommended leg ulcer management, arterial Doppler assessment and compression bandaging, were assessed using multilevel regression.The risk of incident venous leg ulceration increased for patients living in areas of higher deprivation, even after adjustment for known risk factors age and gender. Overall reported rates of Doppler assessment and provision of compression therapy were low, with less than sixteen per cent of patients having a database record of receiving these recommended diagnostic and treatment options. Patients diagnosed with incident venous leg ulcers living in the most deprived areas were less likely to receive the recommended Doppler-aided assessment for peripheral vascular disease than patients living in the least deprived areas (odds ratio 0.43, 95% confidence interval 0.24-0.78. Documented provision of compression therapy did not vary with deprivation.A socio-economic gradient in venous leg ulcer disease was observed. The overall rates of people with venous leg ulcers who were documented as receiving guideline recommended care (2001-2006 were low. Reported use of Doppler ultrasound assessment was negatively associated with socio-economic status. These findings suggest that the

    This study evaluated the stretching and dilatation of venous segments ex vivo in subjects with primary varicose veins in comparison with comparable segments from subjects that used the supplement Pycnogenol (150 mg/d) for 3 months before surgery. Subjects with varicose veins and chronic venous insufficiency voluntarily used Pycnogenol for a period of at least 3 months. The segments of veins removed with surgery (in 30 subjects that had used Pycnogenol and in 10 comparable control subjects that had not used the supplement) were compared with normal, unused vein segments harvested for bypass grafting. The segments were suspended and a weight was attached to the distal part of the veins for 3 minutes and dilated with pressurized water. Digital images were recorded; the veins were measured before and after stretching to evaluate elongation. The manipulation of the vein segment was minimal. Tests were completed within 20 minutes after harvesting the veins. All segments were 4 cm long. The stretching test indicated a significantly higher level of passive elongation in control, varicose segments (2.29; 0.65 mm) in comparison with 1.39; 0.2 mm in vein segments from Pycnogenol-using patients. The dilation test showed an average higher dilation (2.19; 0.3 mm) in control varicose veins in comparison with varicose veins from Pycnogenol-using patients (1.32; 0.7 mm) (p Pycnogenol-using subjects (p Pycnogenol. Varicose segments had a more significant persistent dilatation and elongation in comparison with normal vein segments. Pycnogenol seems to decrease passive dilatation and stretching and gives vein walls a greater tonic recovery and elasticity that allows the vein to recover its original shape after dynamic stresses.

    As compression treatment offers moderate improvement, especially to recurrent venous leg ulcers (VLUs), several alternative therapies using cellular based and/or tissue-derived products (CTPs) have emerged from bovine, porcine, and equine sources. Our aim was to look at the effect of a CTP in 'real-life' VLUs. This study looked at complex patients with chronic, large wounds in a single-centre retrospective review. All patients were treated with fetal bovine acellular dermal matrix (FBADM) for VLUs at our outpatient urban wound care programme. A total of 40 wounds in 33 patients were analysed. At week four, 6% of wounds were closed; at week eight, 9% were closed; at week 12, 25% were closed; and at week 16, 38% of wounds were closed. The median time to wound closure was 67 days (range: 23-100 days) and the median percent wound closure through re-epithelialisation was 11% per week (range: 7-30% per week). At 4 weeks the median area reduction of all wounds was 23.5%, with 40% of VLUs having a ≥40% area reduction at the same point in time. There are limitations to any retrospective review; however; patients deemed to have a limited chance of closure at 4 months did better than expected, either healing or having a wound area reduction at 16 weeks, making their wound care much easier. Prospective studies should be conducted to optimise the treatment algorithm to determine if better clinical outcomes can be obtained for the 'real-life' VLU population.

    Genital ulcers are common manifestations of infectious disease. The incidence of genital ulcers featuring a chronic course has increased since the beginning of the AIDS epidemic. The purpose of this 18-month cross-sectional study was to determine the main infectious causes of chronic genital ulcers (CGU) and their correlation with HIV infection. A total of 29 patients with CGU defined as an ulcer showing no sign of healing after more than one month were studied. Mean age ranged from 24 to 54 years. The male-to-female sex ratio was 1:5. The etiology was herpes in 19 cases (65.5 p. 100), chancroid in 6 cases (20.6 p. 100), streptococcal infection in 2 cases (6.8 p. 100), Pseudomonas aeruginosa infection in 1 case (3.4 p. 100) and cutaneous amibiasis in 1 case (3.4 p. 100). Twenty-two patients (75.8 p. 100) presented HIV infection including 16 with HIV1 and 6 with HIV1 and HIV2. All patients with herpes were HIV-positive. Eighteen of these patients were in stage C3 of HIV infection. Genital herpes was the main etiology of UGC in patients with HIV infection (p < 0.001). Conversely chancroid was the main etiology in patients without HIV infection (p < 0.05). This finding suggests that herpetic CGU is highly suggestive of AIDS whereas chancroid CGU is not. Although syphilis is widespread in Africa, it was not a cause of CGU in this study. Search for herpes simplex virus or Haemophilus ducreyi in patients with CGU is an important criteria for presumptive diagnosis of AIDS in Africa.

    Full Text Available Úlceras venosas são comuns na população adulta, causando significante impacto social e econômico devido a sua natureza recorrente e ao longo tempo decorrido entre sua abertura e cicatrização. Quando não manejadas adequadamente, as úlceras venosas têm altas taxas de falha de cicatrização e recorrência. Apesar da elevada prevalência e da importância da úlcera venosa, ela é freqüentemente negligenciada e abordada de maneira inadequada. Esta revisão discute abordagem diagnóstica e terapêutica das úlceras venosas. O diagnóstico clínico baseia-se em história e exame físico, com ênfase nos sinais e sintomas associados e palpação dos pulsos dos membros inferiores. A ultra-sonografia Doppler deve ser utilizada para determinar o índice pressórico entre o tornozelo e o braço, e exames não invasivos, como o duplex scan, devem ser realizados para avaliar o sistema venoso superficial, profundo e perfurante. Para abordagem terapêutica são fundamentais os diagnósticos clínico e laboratorial corretos, além do diagnóstico e tratamento adequados das complicações das úlceras crônicas. Os esforços devem ser direcionados para a cicatrização da úlcera e, posteriormente, para evitar as recidivas. O grande avanço no conhecimento da fisiopatogenia das úlceras venosas tem permitido o desenvolvimento de novas modalidades de tratamento clínico e cirúrgico.Venous ulcers are common in adult population.

    The aim of this work was to study the safety and effectiveness of silver foam dressing (Contreet® Ag, Coloplast, Humlebaek, Denmark) in promoting the healing of infected venous ulcers over 9 weeks of treatment. Forty-two patients with infected venous ulcers were included and randomized into two groups. Group A had 21 patients (12 women and 9 men, mean age 61.2 years) who were treated with the silver foam for 9 weeks. Group B also had 21 patients (14 women and 7 men, mean age 58.7 years) who were treated with a nonadhesive foam (Biatain®, Coloplast, Humlebaek, Denmark) for 9 weeks. In both groups, ulcer size and depth, intensity of pain, wound exudation, bacterial load, side effects of both materials, and ulcer healing were documented and compared. There was no significant difference at the initial assessment in both groups regarding ulcer size, ulcer depth, grade of exudation, pain intensity, or bacterial load. However, group A ulcers had a significantly greater healing (P = 0.02) compared to group B. Pain intensity was significantly less in group A patients at several time points. After 9 weeks of treatment, the silver foam dressing was found to be a safe material that promotes rapid healing of venous ulcers and relieves pain. .

    The authors present the modern viewpoint concerning the problem of chronic venous insufficiency in the cases of venous forms of dysplasia. The treatment of patients with of venous forms of dysplasia should be based on the principles of interdisciplinary approach, which stipulates both the careful diagnosis on the basis of mainly non-invasive methods and integration of surgical and conservative treatment methods. Today such treatment should be combined and conducted within the multi-purpose highly specialized institution. Only the combination of all treatment methods will allow achieving the best functional and esthetic results. In the cases when indications are absent and conduction of surgical or any other treatment method is impossible it is necessary control the venous anomaly (dynamical follow-up, compression as a basic variant of conservative therapy). It will allow minimizing the unfavorable influence on vital functions and improving the patient's life quality.

    Chronic venous disorders (CVDs) subtend a spectrum of vascular abnormalities, including microcirculation and skin damages (as ulcers) in the lower limb. Mesoglycan has been established as an effective agent to improve microcirculation associated with CVDs. The aim of this study was to determine the beneficial function of mesoglycan on cutaneous blood flow measured by laser Doppler fluometry (LDF) before and after iontophoresis analysis using methacholine chloride (MCh) injection in a group of female patients in different stages of CVDs, according to the CEAP classification. Female patients with chronic venous disorders (CVD) were referred from primary care practices and vascular clinics. The study selected 75 women aged 45.5 ± 9.6 years (range, 30 to 60 years). And grading in CEAP classification. Eligible patients were allocated consecutively, according to entrance order, in an active treatment group and in a control group for 90 days. The active group (N. = 37) received mesoglycan 50 mg twice daily in adjunct to standard care. The primary outcome variable for the study was the measurement of skin microcirculation blood flow by LDF. Data obtained was transferred to a database (Excel) and analysed using statistical software (SPSS version 12, SPSS, USA). After 90 days of treatment, mesoglycan obtained a significative increase in peak flow at LDF of about 13% respect of baseline and standard care in the entire group of CVD treated women. In upper CEAP classes there was a trend for a more intense vasodilating activity of mesoglycan. The study shows improving in microvascular function induced by a 3-month mesoglycan treatment in patients classified by CEAP stages C1 and C4.

    Full Text Available The increasing pressure of modern social life intensifies the impact of stress on the development of cardiovascular diseases, which include deep venous thrombosis (DVT. Renal sympathetic denervation has been applied as one of the clinical approaches for the treatment of drug-resistant hypertension. In addition, the close relationship between oxidative stress and cardiovascular diseases has been well documented. The present study is designed to explore the mechanism by which the renal sympathetic nerve system and the oxidative stress affect the blood coagulation system in the development of DVT. Chronic foot shock model in rats was applied to mimic a state of physiological stress similar to humans. Our results showed that chronic foot shock procedure could promote DVT which may be through the activation of platelets aggregation. The aggravation of DVT and activation of platelets were alleviated by renal sympathetic denervation or antioxidant (Tempol treatment. Concurrently, the denervation treatment could also reduce the levels of circulating oxidation factors in rats. These results demonstrate that both the renal sympathetic nerve system and the oxidative stress contribute to the development of DVT in response to chronic stress, which may provide novel strategy for treatment of clinic DVT patients.

    It has been recognized for over 2000 years that ulceration of the leg may be associated with visible varices of the lower limb. More recent physiological investigation has shown that the pressure in the veins of the lower limb remains raised in patients with venous ulceration during ambulation, whereas in normal subjects the pressure in superficial veins falls to a low level. This elevated pressure appears to cause damage to the superficial capillaries in the skin culminating in the production of venous ulceration. Events in the dermal capillaries which result in skin destruction have yet to be fully defined. Pericapillary fibrin cuffs have been demonstrated histologically and suggested as a cause of diminished nutrition to the skin. White blood cells have been shown to accumulate in the lower limb of patients with venous disease and these accumulations are particularly located around the dermal capillaries. Activated white blood cells releasing free radicals and destructive enzymes may precipitate skin destruction. An understanding of these mechanisms may help to explain the efficacy of compression hosiery and bandaging as well as some of the new pharmacological agents which have been shown to influence venous ulcer healing.

    Venous leg ulcers (VLU) are characterized by sustained proteolytic microenvironment impairing the healing process. Wound fluid (WF) reflect the biomolecular activities occurring within the wound area; however, it is unclear if WF from different healing phases have different proteolytic profiles and how VLU microenvironment affects the wound healing mechanisms. We investigated the proteolytic network of WF from distinct VLU phases, and in WF- and LPS-stimulated THP-1 monocytes treated with glycosaminoglycan sulodexide, a well known therapeutic approach for VLU healing. WF were collected from patients with VLU during inflammatory (Infl) and granulating (Gran) phases. WF and THP-1 supernatants were analyzed for nine matrix metalloproteinases (MMP) and four tissue inhibitors of metalloproteinases (TIMP) by multiplex immunoassays. Our results demonstrated that: 1) WF from Infl VLU contained significantly increased concentrations of MMP-2, MMP-9, MMP-12, TIMP-1, and TIMP-2 compared to Gran WF; 2) WF from Gran VLU showed significantly increased levels of MMP-1, MMP-7, MMP-13, and TIMP-4 compared to Infl WF; 3) LPS- and WF-stimulation of THP-1 cells significantly increased the expression of several MMP compared to untreated cells; 4) Sulodexide treatment of both LPS- and WF-stimulated THP-1 significantly down-regulated the release of several MMPs. Our study provides evidence-based medicine during treatment of patients with VLU. WF from Infl and Gran VLU have different MMP and TIMP signatures, consistent with their clinical state. The modulation of proteolytic pathways in wound microenvironment by glycosaminoglycan sulodexide, provide insights for translating research into clinical practice during VLU therapy.

    Skin affected by a burn cancer is scarred, ulcerated, and often appears as erythema ab igne clinically in adjacent skin. The latent period in burn scar malignancy is much longer for SCC than BCC. Malignant melanoma and various sarcomas are reported to arise in burn scars, too. The other extreme on the temperature scale can less often result in enough permanent acral damage that poor wound healing may eventually result in cancer, usually SCC. About 1% of patients with chronic osteomyelitis develop cancer, usually SCC in sinus tracts. As with tumors arising in burn scars and chronic leg ulcers of varied etiology, black patients are disproportionately overrepresented in osteomyelitic malignancy. In nearly all of the patients with radiation-induced skin cancer, concomitant radiodermatitis is present. As with burn scar and osteomyelitic cancer, x-ray related cancer has a long latent period. Similar to burn scar cancer, SCC predominates in osteomyelitis and occurs on the extremities. BCC, when it arises, is more common on the face and neck in burn- and radiation-induced tumors. Multiple tumors are frequent as is recurrence in x-ray malignancy. Mortality is high: one out of three to four patients with burn scar, osteomyelitic, and radiation cancer die of dermatosis-related malignancy. Recently, radioactivity-contaminated gold rings have been implicated in causing SCC. Carcinoma tends to occur in irradiated benign dermatoses whereas sarcomas tend to complicate irradiated malignancies. Stasis ulceration and anogenital fistulae may rarely lead to cancer, SCC in the former and adenocarcinoma in the latter. SCC can rarely develop in four related conditions (acne conglobata, dissecting perifolliculitis of the scalp, hidradenitis suppurativa, and pilonidal sinus) after a lengthy latent period; prognosis is poor with a high metastatic rate. 147 references.

    The societal and individual burden caused by acute and chronic lower extremity venous disease is considerable. In the past several decades, minimally invasive endovascular interventions have been developed to reduce thrombus burden in the setting of acute deep venous thrombosis to prevent both short- and long-term morbidity and to recanalize chronically occluded or stenosed postthrombotic or nonthrombotic veins in symptomatic patients. This state-of-the-art review provides an overview of the techniques and challenges, rationale, patient selection criteria, complications, postinterventional care, and outcomes data for endovascular intervention in the setting of acute and chronic lower extremity deep venous disease.

    Full Text Available Objective: the mean platelet volume (MPV is a good indicator of platelet activity; it is reported to increase in diseases associated with inflammatory processes and in vascular diseases. This study investigated the importance of mean platelet volume in patients with chronic venous insufficiency (CVI and whether the MPV was likely to be a predictor of the CVI. Methods: 117 patients who were diagnosed as CVI by colored Doppler Ultrasound (CDU method and 49 healthy volunteers (forming the control group were en­rolled to this study, which was planned retrospectively. The patients’ blood count values taken within one month before and after the CDU evaluation were recorded by the hospital information system. The complete blood count, routine biochemical tests and thyroid function tests of the patients diagnosed with CVI were compared to the control group. Results: Significant differences were not detected be­tween the patients and the control group in terms of the levels of creatinine, aspartate aminotransferase, total cholesterol, LDL cholesterol, HDL cholesterol, triglycer­ides, erythrocyte, sedimentation speed, leukocyte, hae­moglobin and thrombocyte (p>0.05. The thyroid stimulat­ing hormone and the MPV levels were significantly lower in the control group (p<0.05. Conclusion: MPV levels as an easy, cheap and practi­cal data extracted from complete blood count, were found higher in patients diagnosed with CVI compared to the control group. This may be originated from endothelium changes as an answer to venous hypertension and dila­tation in CVI. MPV can be used as a follow-up marker in CVI patients. J Clin Exp Invest 2016; 7 (1: 73-77

  16. Effectiveness of acupuncture, special dressings and simple, low-adherence dressings for healing venous leg ulcers in primary healthcare: study protocol for a cluster-randomized open-labeled trial

    Full Text Available Abstract Background Venous leg ulcers constitute a chronic recurring complaint that affects 1.0–1.3% of the adult population at some time in life, and which corresponds to approximately 75% of all chronic ulcers of the leg. Multilayer compression bandaging is, at present, the only treatment that has been proved to be effective in treating this type of ulcer. There is no consensus, however, about the dressings that may be applied, beneath the compression, to promote the healing of this type of ulcer, as there does not seem to be any added benefit from using special dressings rather than simple, low-adherence ones. As well as analgesia, acupuncture provokes peripheral vasodilation, in skin and muscles – which has been demonstrated both experimentally and in clinical practice – probably due to the axon reflex, among other mechanisms. The aim of the present study is to measure the effectiveness and cost of compression treatment for venous leg ulcers combined with special dressings, in comparison with low-adherence ones and acupuncture. Methods/design Cluster-randomized open-labeled trial, at 15 primary healthcare clinics in the Sevilla-Sur Healthcare District, with a control group treated with compression bandaging and low-adherence dressings; the experiment will consist, on the one hand, of the compression treatment applied in combination with special dressings (Treatment 1, and on the other, the compression treatment applied in association with low-adherence dressings, together with acupuncture (Treatment 2. Discussion The results will be measured and recorded in terms of the median time elapsed until complete healing of the ulcer, and the rate of complete healing at 3 months after beginning the treatment. An economic analysis will also be made. This study, carried out in the context of real clinical practice, will provide information for decision-taking concerning the effectiveness of special dressings. Moreover, for the first time a high

The specific instruments that measure HRQL in These people are not available in Spanish. Therefore, it is need for such an instrument adapted and validated in Spanish. The aim of this study is the cultural adaptation to Spanish in one of these instruments, namely the Charing Cross Venous Ulcer Questionnaire (CCVUQ. Materials and methods: the original version of the questionnaire CCVUQ, which includes 20 questions, has been adapted into Spanish following the methodology of translation and back-translation and the establishment of cultural semantic equivalences. In the adaptation process has involved a group of experts in chronic wounds and a group of patients with these lesions. Results: we obtained a satisfactory version of the questionnaire translated and adapted culturally CCVUQ Spain, with the realization of "minor adjustments to the original questions, but necessary for the understanding of the local population in order to save the semantic and conceptual equivalence of the original version. Discussion and conclusions: the Spanish version of CCVUQ is semantically and culturally equivalent to the original English version. It is an instrument with simple questions during the process has been altered from the contributions and suggestions from experts and patients, which did not affect their essence, and that has ensured an adequate pre-test version, adapted to the Spanish language and Spanish culture. At a later stage will be carried out an investigation to validate and test the psychometric properties adapted to Spanish.

    The aim of this study was to confirm a fact known in the relevant literature that there is a correlation between static anomalies of the sole, and varicose veins, a consequence of the decreased quality of the conjunctive tissue. We cite genetic and dynamic factors by way of explanation. To confirm the fact that deformities of the sole of the foot are linked with chronic venous incompetence and influence the functional capacity of the muscular pump, the authors have analysed in young subjects the contractile capacity of the pump even when the index of reduction in the sole of the foot was quite low. The muscular pump in the calf is a compensatory system from the point of view of functional capacity. The authors noted that the velocimetric parameter of speed of flux in the femoral vein is a sensitive parameter and changes rapidly, rising with even minimal activity in the calf. The authors think that acquired deformities are one of the most frequent causes of the poor functioning of the muscular pump in the calf.

    Full Text Available Episodes of acute pancreatitis have been described during the course of ulcerative colitis and most of them are due to cholelithiasis or drugs. Idiopathic pancreatitis has rarely been associated with inflammatory bowel disease (IBD. We describe one such case. A 35-year-old male presented in 2001 with a ten year history of recurrent episodes of diarrhea without blood and mucus in the stools. Four years ago, he developed an episode of mild acute pancreatitis. At that time, the serum amylase level was three times the upper normal limit. He was treated conservatively. A month later, he was found to be diabetic and was put on insulin. He was non-alcoholic and there was no history of any chronic drug use. There was no similar family history.

    AIM: To investigate the occurrence of chromosome 3, 7,8, 9, and 17 aneuploidies, TP53 gene deletion and p53 protein expression in chronic gastritis, atrophic gastritis and gastric ulcer, and their association with H pylori infection.METHODS: Gastric biopsies from normal mucosa (NM,n = 10), chronic gastritis (CG,n =38), atrophic gastritis (CAG, n=13) and gastric ulcer (GU, n = 21) were studied using fluorescence in situ hybridization (FISH) and immunohistochemical assay. A modified Giemsa staining technique and PCR were used to detect H pylori. An association of the gastric pathologies and aneuploidies with H pylori infection was assessed.RESULTS: Aneuploidies were increasingly found from CG (21%) to CAG (31%) and to GU (62%), involving mainly monosomy and trisomy 7, trisomies 7 and 8, and trisornies 7, 8 and 17, respectively. A significant association was found between H pylori infection and aneuploidies in CAG (P= 0.0143) and GU (P= 0.0498). No TP53 deletion was found in these gastric lesions, but p53-positive immunoreactivity was detected in 45% (5/11) and 12% (2/17) of CG and GU cases, respectively. However, there was no significant association between p53 expression and H pylori infection.CONCLUSION: The occurrence of aneuploidies in benign lesions evidences chromosomal instability in early stages of gastric carcinogenesis associated with H pylori infection, which may confer proliferative advantage. The increase of p53 protein expression in CG and GU may be due to overproduction of the wild-type protein related to an inflammatory response in mucosa.

    Full Text Available Hitomi Sano,1 Sachio Kouraba,2 Rei Ogawa11Department of Plastic, Reconstructive, and Aesthetic Surgery, Nippon Medical School, Tokyo, Japan; 2Sapporo Wound Care and Anti-Aging Laboratory, Sapporo, JapanAbstract: Chronic leg ulcers are a significant health care concern. Although deep wounds are usually treated by flap transfers, the operation is invasive and associates with serious complications. Skin grafts may be a less invasive means of covering wounds. However, skin grafts cannot survive on deep defects unless high-quality granulation tissue can first be generated in the defects. Technologies that generate high-quality granulation tissue are needed. One possibility is to use wound care matrices, which are bioengineered skin and soft tissue substitutes. Because they all support the healing process by providing a premade extracellular matrix material, these matrices can be termed “extracellular matrix replacement therapies”. The matrix promotes wound healing by acting as a scaffold for regeneration, attracting host cytokines to the wound, stimulating wound epithelialization and angiogenesis, and providing the wound bed with bioactive components. This therapy has lasting benefits as it not only helps large skin defects to be closed with thin skin grafts or patch grafts but also restores cosmetic appearance and proper function. In particular, since it acts as a layer that slides over the subcutaneous fascia, it provides skin elasticity, tear resistance, and texture. Several therapies and products employing wound care matrices for wound management have been developed recently. Some of these can be applied in combination with negative pressure wound therapy or beneficial materials that promote wound healing and can be incorporated into the matrix. To date, the clinical studies on these approaches suggest that wound care matrices promote spontaneous wound healing or can be used to facilitate skin grafting, thereby avoiding the need to use

    The pattern of contact sensitization among patients with chronic leg ulcers depends on the local practice of wound treatment along with demographic and clinical confounders. The study was aimed at revealing the associations between chronic leg ulcers and contact sensitization. Between 2006 and 2008, 35 patients with chronic leg ulcers and surrounding dermatitis and 59 patients with contact dermatitis of the lower leg or foot were prospectively recruited at the Department of Skin and Venereal Diseases, Lithuanian University of Health Sciences. Demographic and clinical data were collected in accordance with the "minimal data set" of the European Surveillance System on Contact Allergy. Patch testing was performed with the allergens of the European baseline series. At least one positive patch test reaction was found in 28 (80%) of the patients with chronic leg ulcers and in 24 (41%) of the patients with dermatitis of the lower leg or foot (Pmethyldibromo glutaronitrile, was prevalent in both the groups of patients, whereas sensitization to benzocaine, p-phenylenediamine, and lanolin alcohol was associated with the presence of chronic leg ulcers. Benzocaine was found to be the leading allergen among patients with chronic leg ulcers (positive patch test reactions in 34.4% of the patients). Contact sensitization to benzocaine, p-phenylenediamine, and lanolin was found to be associated with the presence of chronic leg ulcers.

    AIM: To investigate EP4-selective agonist effect on indomethacin-induced gastric lesions and on the spontaneous healing of chronic gastric ulcers. METHODS: In a mouse model of gastric bleeding with high dose of indomethacin (20 mg/kg), an EP4-selective agonist was administered orally. Stomach lesions and gastric mucous regeneration were monitored. In a mouse model of chronic gastric ulcer induced by acetic acid, EP4 agonist effect on the healing of chronic gastric ulcer was evaluated in the presence or absence of low dose indomethacin (3 mg/kg). In cultured human gastric mucous cells, EP4 agonist effect on indomethacininduced apoptosis was assessed by flow cytometry. RESULTS: The EP4-selective agonist reduced high dose indomethacin-induced acute hemorrhagic damage and promoted mucous epithelial regeneration. Low-dose indomethacin aggravated ulcer bleeding and inflammation, and delayed the healing of the established chronic gastric ulcer. The EP4 agonist, when applied locally, not only offset indomethacin-induced gastric bleeding and inflammation, but also accelerated ulcer healing. In the absence of indomethacin, the EP4 agonist even accelerated chronic gastric ulcer healing and suppressed inflammatory cell infiltration in the granulation tissue. In vitro , the EP4 agonist protected human gastric mucous cells from indomethacin-induced apoptosis. CONCLUSION: EP4-selective agonist may prevent indomethacin-induced gastric lesions and promote healing of existing and indomethacin-aggravated gastric ulcers, via promoting proliferation and survival of mucous epithelial cells.

  9. Targeting Cx43 and N-cadherin, which are abnormally upregulated in venous leg ulcers, influences migration, adhesion and activation of Rho GTPases.

    Ariadna Mendoza-Naranjo

    Full Text Available BACKGROUND: Venous leg ulcers can be very hard to heal and represent a significant medical need with no effective therapeutic treatment currently available. PRINCIPAL FINDINGS: In wound edge biopsies from human venous leg ulcers we found a striking upregulation of dermal N-cadherin, Zonula Occludens-1 and the gap junction protein Connexin43 (Cx43 compared to intact skin, and in stark contrast to the down-regulation of Cx43 expression seen in acute, healing wounds. We targeted the expression of these proteins in 3T3 fibroblasts to evaluate their role in venous leg ulcers healing. Knockdown of Cx43 and N-cadherin, but not Zonula Occludens-1, accelerated cell migration in a scratch wound-healing assay. Reducing Cx43 increased Golgi reorientation, whilst decreasing cell adhesion and proliferation. Furthermore, Connexin43 and N-cadherin knockdown led to profound effects on fibroblast cytoskeletal dynamics after scratch-wounding. The cells exhibited longer lamelipodial protrusions lacking the F-actin belt seen at the leading edge in wounded control cells. This phenotype was accompanied by augmented activation of Rac-1 and RhoA GTPases, as revealed by Förster Resonance Energy Transfer and pull down experiments. CONCLUSIONS: Cx43 and N-cadherin are potential therapeutic targets in the promotion of healing of venous leg ulcers, by acting at least in part through distinct contributions of cell adhesion, migration, proliferation and cytoskeletal dynamics.

    Full Text Available Objective:Iliocaval obstruction is associated with venous hypertension symptoms and may predispose to deep venous thrombosis (DVT. Ultrasonography may fail to achieve noninvasive diagnosis of these obstructions. The possibility of using Computed Tomography Venography (CTV for these diagnoses is under investigation.Methods:Patients with CVI graded at CEAP clinical classes 3 to 6 and previous treatment failure underwent evaluation with CTV. Percentage obstruction was rated by two independent examiners. Obstruction prevalence and its associations with risk factors and CEAP classification were analyzed.Results:A total of 112 limbs were prospectively evaluated. Mean patient age was 55.8 years and 75.4% were women. Obstructions involved the left lower limb in 71.8% of cases and 35.8% of patients reported a medical history of deep venous thrombosis. Overall, 57.1% of imaging studies demonstrated venous obstruction of at least 50% and 10.7% showed obstruction of >80%. The only risk factor that was found to be independently associated with a significantly higher incidence of >50% venous obstruction was a medical history of DVT (p=0.035 (Fisher's exact test. There was a positive relationship between clinical classification (CEAP and degree of venous obstruction in the limbs studied (Chi-square test for linear trend; p=0.011.Conclusion:Patients with advanced CVI are often affected by obstructions in the iliocaval venous territory and CTV is able to diagnose the degree of obstruction. There is a positive association between degree of obstruction and both previous history of DVT and severity of symptoms of CVI.

    2012-10-01

    There is a strong body of circumstantial evidence which implicates genetics in the aetiology and pathology of varicose veins and venous ulcer disease. The aim of this review is to consider the current knowledge of the genetic associations and the ways in which new genetic technologies may be applied to advancing our understanding of the cause and progression of these venous diseases. A number of publications have used a candidate gene approach to identify genes implicated in venous disease. Although these studies have opened up important new insights, there has been a general failure to replicate results in an independent cohort of patients. With our limited knowledge of the biological pathways involved in the pathogenesis of venous disease we are not in a strong position to formulate truly erudite a priori candidate gene hypothesis-directed studies. A genome-wide association study should therefore be considered to help further our understanding of the genetic basis of venous disease. Due to the large sample sizes required for discovery and validation, using the new generations of molecular technologies, it will be necessary to form collaborating groups in order to successfully advance the field of venous disease genetics.

    To analyze the presence of chronic cerebrospinal venous insufficiency parameter and vascular abnormalities, in the internal jugular veins (IJVs) and/or vertebral veins in sitting and supine posture, in patients with Meniere's disease compared to healthy general population. A prospective study on 32 patients affected by definite Ménière was performed from February 2012 to January 2013. All subjects underwent an echo-color Doppler examination of the cerebrospinal venous flow. 21 of the 32 Menieric patients showed a statistically significant reflux in the intracranial veins versus healthy (65.6 vs 25%; P venous system present in patients affected by definite Meniere. This vascular impairment significantly affects the vascular areas more directly involved in the venous drainage of the inner ear. Thus venous stasis may be considered a further pathogenetic mechanism for development of Meniere's disease.

    The purpose of this study was to examine if there is a relation between the aldosterone escape phenomenon and venous capacitance of the upper and lower limbs in patients with long-term congestive heart failure (CHF) receiving chronic treatment with angiotensin-converting enzyme (ACE) inhibitors. The study group consisted of 16 subjects with ischemic CHF in New York Heart Association functional class II (age 59 +/-2 years, ejection fraction 24+/-4%), stabilized under a constant drug regimen comprising furosemide, captopril 50 mg 3 times daily, and digoxin for at least 3 months. Thirteen apparently healthy volunteers, aged 50+/-4 years acted as controls. Forearm and calf venous capacitances were measured simultaneously by venous occlusion plethysmography using mercury-in-silastic strain gauges. The equilibration technique was used to derive venous capacitance from the recorded pressure-volume curves. Active renin, angiotensin II, and aldosterone levels were determined on venous blood samples obtained in the supine position. Angiotensin II (paldosterone (paldosterone escape phenomenon). In CHF, forearm venous capacitance was 2.19+/-0.18 ml/100 ml; calf venous capacitance was 2.83+/-0.27 ml/100 ml. Aldosterone significantly and inversely correlated with venous capacitance in both upper (r = -0.586; p = 0.017) and lower (r = -0.625; p = 0.01) limbs. No correlations were found between forearm or calf venous capacitance and renin or angiotensin II. In patients with heart failure chronically treated with diuretics and full ACE inhibition, venous capacitance is inversely correlated with aldosterone through the mechanism of aldosterone escape, creating the potential for further deterioration of the CHF process.

    Two Scottish terrier dogs were presented for recurrent oral problems. They were diagnosed with refractory chronic ulcerative paradental stomatitis and necrosis of the incisive and maxillary bones. Both dogs were treated with a combination of bilateral rostral maxillectomy and tooth extractions. The ostectomy was performed with a specific cutting device using piezoelectric bone surgery technology. These two cases show that a precise evaluation of dogs is essential for the diagnose of chronic ulcerative paradental stomatitis and its differentiation from mucocutaneous autoimmune diseases.

    Full Text Available Varicose ulcers are wounds that are thought to occur due to improper functioning of venous valves usually of the legs. They are the major occurrence of chronic wounds occurring in 70 to 90 of leg ulcer cases. In Sushrut Samhita where get the most scientific description of wound and its management. Similarly Sushrut has given the almost importance to Bloodletting therapy and considered leech as the most unique and effective method of bloodletting even in infected wounds and abscesses. Aforesaid description let us to try leech therapy in venous ulcer was advised to continue weekly application of leech around the ulcer which was followed by dressing with Seethodaka oil and Dashanga lepa. This leech therapy proved very effective and the ulcer healed completely within 30 days. However further evaluation is required to be done by taking a large samples size to prove its significant in treating Venous ulcer.

    Chronic venous insufficiency (CVI) is the most advanced form of chronic venous disease (CVD), and is often associated with skin changes such as hyperpigmentation, eczema, lipodermatosclerosis and venous skin ulceration that cause discomfort, pain, sleep disturbances, absenteeism in the workplace, disability and deteriorated quality of life (QoL). The purpose of this study is to evaluate the prevalence of CVI and skin changes in patients who turn to Continuous Assistance Services due to the presence of disturbing symptoms of their condition. Data were evaluated by consulting the medical records, during a 16-month period, available with three Continuous Assistance Services of the Italian territory. The overall population of the referring centres consisted of 1186 patients [739 females (62·31%) and 447 males (37·69%)]. Seventy-nine patients (6·66%) consulted the emergency unit for venous symptoms related to CVD. Patients with more severe disease (CVI, categories C4-C6) represented the majority accounting for 60·75%, while patients with moderate disease (C3) accounted for 35·44% and patients with mild disease (C1-C2 stages) accounted for 3·79%. The main finding of this study is that despite CVI not being a disease that commonly requires medical emergency/urgency intervention, patients with CVI, especially in advanced stage with skin changes, may turn to Continuous Assistance Service for treating bothersome symptoms related to their condition.

    Between 1983 and 1994, 66 Senegalese leprosy patients were seen for cauliflower growths developed in chronic plantar ulcer (CPU), (2 patients had each 2 tumors). 68 biopsies for pathological examination were taken: the diagnosis of squamous cell carcinoma was effectively made in 39 cases (38 patients) and that of pseudo-epitheliomatous hyperplasia in the remaining 29 cases (28 patients). The mean annual frequency of cauliflower growths was 0.45 per 100 CPU. Among these tumors, the percentage of carcinoma was 57%. Of the 38 patients with a carcinoma, 5 refused amputation and all of them died. The 33 others were amputated and of these 8 died as a direct result of their carcinoma (24%). In the case of the 28 patients with hyperplasia, amputation was carried out on 18 patients and local excision on 10. In the months following the operation 8 recurrences were observed in 10 of the patients on whom excision had been carried out. These recurrences were treated by amputation. This gives a total of 93% of amputations in the cases of hyperplasia. These facts lead as to conclude that at least in countries where pathological examination is not available below knee amputation is the most reasonable action to take in the proliferative tumors developed on a CPU.

    Between 1988 and 1992, 21 biopsies for pathological examination were taken from 20 Senegalese leprosy patients suffering from chronic plantar ulcers (CPU) suspected of malignant transformation. The diagnosis of squamous cell carcinoma was effectively made in 13 cases and that of pseudoepitheliomatous hyperplasia in the remaining 8 cases. The mean period of time between the onset of CPU and that of malignant transformation was 10 years (range: 1 to 15 years); the mean annual frequency of the malignant transformation was 2 per 1,000 CPU. In countries where pathological examination is not available, below knee amputation could be considered whenever main clinical signs of malignant transformation are present. In countries where pathological examination is available, the therapeutic decision may differ according to the diagnosis: below knee amputation supplemented with block dissection of inguinal lymph nodes whenever possible in cases of carcinoma; below knee amputation depending on the function status of the foot and on the volume of tumor in case of pseudo-epitheliomatous hyperplasia.

    To assess the clinical effectiveness of weekly delivery of low dose, high frequency therapeutic ultrasound in conjunction with standard care for hard to heal venous leg ulcers. Multicentre, pragmatic, two arm randomised controlled trial. Community and district nurse led services, community leg ulcer clinics, and hospital outpatient leg ulcer clinics in 12 urban and rural settings (11 in the United Kingdom and one in the Republic of Ireland). 337 patients with at least one venous leg ulcer of >6 months' duration or >5 cm(2) area and an ankle brachial pressure index of ≥ 0.8. Weekly administration of low dose, high frequency ultrasound therapy (0.5 W/cm(2), 1 MHz, pulsed pattern of 1:4) for up to 12 weeks plus standard care compared with standard care alone. Primary outcome was time to healing of the largest eligible leg ulcer. Secondary outcomes were proportion of patients healed by 12 months, percentage and absolute change in ulcer size, proportion of time participants were ulcer-free, health related quality of life, and adverse events. The two groups showed no significant difference in the time to healing of the reference leg ulcer (log rank test, P=0.61). After adjustment for baseline ulcer area, baseline ulcer duration, use of compression bandaging, and study centre, there was still no evidence of a difference in time to healing (hazard ratio 0.99 (95% confidence interval 0.70 to 1.40), P=0.97). The median time to healing of the reference leg ulcer was inestimable. There was no significant difference between groups in the proportion of participants with all ulcers healed by 12 months (72/168 in ultrasound group v 78/169 in standard care group, P=0.39 for Fisher's exact test) nor in the change in ulcer size at four weeks by treatment group (model estimate 0.05 (95% CI -0.09 to 0.19)). There was no difference in time to complete healing of all ulcers (log rank test, P=0.61), with median time to healing of 328 days (95% CI 235 to inestimable) with standard care

    'Hard-to-heal' wounds are those which fail to heal with standard therapy in an orderly and timely manner and may warrant the use of advanced treatments such as non-contact low-frequency ultrasound (NLFU) therapy. This evaluator-blinded, single-site, randomised controlled trial, compared NLFU in addition to UK standard of care [SOC: (NLFU + SOC)] three times a week, with SOC alone at least once a week. Patients with chronic venous leg ulcers were eligible to participate. All 36 randomised patients completed treatment (17 NLFU + SOC, 19 SOC), and baseline demographics were comparable between groups. NLFU + SOC patients showed a -47% (SD: 38%) change in wound area; SOC, -39% (38%) change; and difference, -7·4% [95% confidence intervals (CIs) -33·4-18·6; P = 0·565]. The median number of infections per patient was two in both arms of the study and change in quality of life (QoL) scores was not significant (P = 0·490). NLFU + SOC patients reported a substantial mean (SD) reduction in pain score of -14·4 (14·9) points, SOC patients' pain scores reduced by -5·3 (14·8); the difference was -9·1 (P = 0·078). Results demonstrated the importance of high-quality wound care. Outcome measures favoured NLFU + SOC over SOC, but the differences were not statistically significant. A larger sample size and longer follow-up may reveal NLFU-related improvements not identified in this study.

Studies with periodontal fibroblasts indicate that attachment to these structures increases the endogenous secretion of multiple growth factors and cell proliferation. Pre-clinical and clinical studies indicate that cutaneous wounds benefit from treatment with amelogenins. A randomized controlled trial (RCT involving patients with hard-to-heal venous leg ulcers (VLUs (ie, ulcers with a surface area ≥10 cm2 and duration of ≥6 months showed that the application of amelogenin (Xelma®, Molnlycke Health Care, Gothenburg, Sweden as an adjunct treatment to compression results in significant reduction in ulcer size, improvement in the state of ulcers, reduced pain, and a larger proportion of ulcers with low levels of exudate, compared with treatment with compression alone. Amelogenin therapy was also shown to be safe to use in that there were no significant differences in adverse events noted between patients treated with amelogenin plus compression and those treated with compression alone. Case study evaluations indicate that the benefits of amelogenin therapy demonstrated in the RCT are being repeated in “real life” situations and that amelogenin therapy may also have a role to play in the treatment of other wound types such as diabetic foot ulcers.Keywords: extracellular matrix, amelogenin, venous leg ulcers, diabetic foot ulcers, pyoderma gangrenosum

    OBJECTIVE To discuss the influence of bacterial infections on the healing of venous leg ulcers so as to provide basis for the clinical treatment of venous leg ulcers. METHODS A total of 590 cases of venous leg ulcer patients were selected and their ulcer tissue samples were sampled before the treatment. The 398 patients whose venous leg ulcers were totally cured were set as the complete heal group, the others as the incomplete heal group. The tissue samples of two groups were studied for the bacteria species. A six-month follow-up was conducted after the treatment, then the influence of bacterial infection for the union of venous leg ulcers was discussed. RESULTS The pathogens were detected in all of the tissue samples of the two case groups. In the complete heal group , the positive rates of Staphylococcusaureus , Staphylococcus epidermidis , and Pseudomonas aeruginosa were 66.7%, 10. 3%, and 40. 45% , respectively , and the difference in the positive rate between the complete heal group and the incomplete heal group was not statistically significant. The total bacterial colony count was significantly less in the complete heal group than in the incomplete heal group. The difference was statistically significant (P<0. 05). CONCLUSION There is no direct relation between the content of the single species of bacteria and the venous leg ulcer , but the total content is closely related to the healing of the venous leg ulcer. We should strengthen the protection of the surface of venous leg ulcer so as to avoid the bacterial growth.%目的 探讨病原菌感染对下肢静脉溃疡愈合的影响,为临床治疗下肢静脉溃疡提供依据.方法 选择2009年1月-2012年1月590例下肢静脉溃疡患者,将下肢静脉溃疡完全愈合的398例患者为完全愈合组,未完全愈合的192例患者为未完全愈合组;治疗前获取其溃疡的组织样本,治疗后进行6个月随访,对两组患者的治疗前溃疡组织样品进行病原菌的检测,探讨

    Helicobacter pylori infection is involved in the formation of chronic peptic ulcer. However, a previously reported hypothesis concerning the involvement of central autonomic nervous disorder in this condition cannot be ruled out. To use spectrum analysis of heart rate viability to examine autonomic nervous activity before and after H. pylori eradication. Twenty patients with chronic duodenal ulcer (duodenal ulcer group) and 20 age-matched normal adults (N group). In both groups, 24-h Holter electrocardiograms (ECGs) were recorded and spectrum analysis of heartrate variability was performed. In the duodenal ulcer group, Holter ECG was recorded before and after H. pylori eradication. In the N group, analysis of heart rate variability showed that high frequency (HF) power, an index of parasympathetic activity, was high at night, while the low frequency (LF)/HF ratio, an index of sympathetic function, was high during the daytime. In the duodenal ulcer group, HF power was higher at night than during the daytime, showing a similar pattern to the N group, but the power value was higher than in the N group (P < 0.05). In the duodenal ulcer group, LF/HF at night was significantly higher than that of the N group. In addition, in the duodenal ulcer group, autonomic activity after H. pylori eradication did not differ significantly from that before H. pylori eradication. In patients with chronic peptic ulcer, both sympatheticotonia and parasympatheticotonia may occur at night, and this abnormality in autonomic nervous activity may cause increased gastric acid secretion and gastric mucosal vasoconstriction. Abnormalities in autonomic activity persist even after H. pylori eradication, suggesting that they may be an independent risk factor in the formation of chronic peptic ulcer in addition to H. pylori infection.

    Full Text Available Optical coherence tomography (OCT is a non-invasive method for the assessment of optic nerve fibers and retinal ganglion cells. This study was aimed at the assessment of retinal abnormalities in multiple sclerosis patients in the context of chronic cerebrospinal venous insufficiency using OCT of the retina and the optic nerve. We examined 239 multiple sclerosis (MS patients, including 220 patients with associated chronic cerebrospinal venous insufficiency and 19 MS patients without venous pathology. The following OCT parameters were assessed: average ganglion cell complex thickness, global loss volume, focal loss volume and average retinal nerve fibre layer thickness. Abnormalities in the azygous and internal jugular veins were evaluated using catheter venography. We found a higher prevalence of abnormal OCT parameters in the patients with previous history of optic neuritis, not only on the side of inflammatory event, but also in the contralateral eye, which is in line with already existing body of evidence. The new and intriguing discovery is that we found statistically significant higher prevalence of abnormal OCT values in multiple sclerosis patients with unilateral stenosis of internal jugular vein. Patients who were not found venous abnormalities, as well as those presenting with pathologic azygous or bilateral internal jugular venous outflows, did not demonstrate a changed frequency of abnormal OCT parameters. Potential association between venous malformations and eye manifestations of multiple sclerosis, as has been demonstrated in this report, justifies further studies on this topic.

    Full Text Available Abstract Background Implementation of lifestyle interventions in patient care is a major challenge. Understanding factors that influence implementation is a first step in programs to enhance uptake of these interventions. A lifestyle-counseling intervention, Lively Legs, delivered by trained nurses, can effectively improve the lifestyle in patients with venous leg ulcers. The aim of this study was to identify factors that hindered or facilitated implementation of this intervention in outpatient dermatology clinics and in home care. Methods A mixed-methods multiple case study in five purposefully selected healthcare settings in the Netherlands was conducted. Measurements to identify influencing factors before and after implementation of Lively Legs included interviews, focus groups, questionnaires, and nurses’ registration. Analyses focused on qualitative data as the main data source. All data were compared across multiple cases to draw conclusions from the study as a whole. Results A total of 53 patients enrolled in the Lively Legs program, which was delivered by 12 trained nurses. Barriers for implementation were mainly organizational. It was difficult to effectively organize reaching and recruiting patients for the program, especially in home care. Main barriers were a lack of a standardized healthcare delivery process, insufficient nursing time, and a lack of motivated nurses to deliver the program. Facilitating factors were nurse-driven coordination of care and a standardized care process to tie Lively Legs into, as this resulted in better patient recruitment and better program implementation. Conclusions This study identified a range of factors influencing the implementation of a lifestyle-counseling program, mainly related to the organization of healthcare. Using a case study method proved valuable in obtaining insight into influencing factors for implementation. This study also shed light on a more general issue, which is that leg ulcer

    2006-01-01

    Full Text Available Chronic leg ulcers are rare in young adults and generally indicate a vascular cause. We report a case of a 26-year-old man with leg ulcers of eight months duration. Doppler study indicated venous incompetence and a postphlebitic limb. However, as the distribution and number of ulcers was not consistent with stasis alone and no features of collagen vascular disease were noted, a hyperviscosity state was considered and confirmed with significantly elevated homocysteine level in the serum. Administration of vitamins B1, B2, B6 and B12, trimethyl-glycine, mecobalamine, folic acid and povidone iodine dressings with culture-directed antibiotic therapy led to a satisfactory healing of ulcers over a period of one month. Hyperhomocysteinemia must be considered in the differential diagnosis of leg ulcers in young individuals.

Fifty patients were randomized to receive one of the five investigational vehicles. Treatment was performed up to complete healing or to a maximum of 29 days. The wound size reduction from baseline was the primary efficacy variable, which was measured by means of a noninvasive laser scanner instrument for wound assessment. In all groups, apart from the foam group, a similar trend toward the reduction of the surface area was observed. The cream showed the greatest effect on the mean reduction of the lesion size. At last visit, six ulcers were healed: two in the cream group, three in the gauze group, and one in the dressing gel group. In the patients treated with the cream, the gauzes, the hydrogel, and the dressing gel, the reduction of lesion size was 40%–50%; the reduction was smaller in the foam group. No impact in terms of age on the healing process was found. The Total Symptoms Score decreased in all groups during the study; a greater efficacy in terms of signs/symptoms was observed in the patients treated with the gauzes. In the dressing gel group, one patient had an infection of the wound after 3 weeks of treatment and 2 of colonization, leading to a systemic antibiotic treatment. The events were judged as nonrelated to the device used. On the basis of the results, it could be argued that the medical device may be useful in the treatment of chronic venous ulcers.

    This paper reports the beneficial effects of ozone autohemotherapy (OHT) in 2 patients afflicted with painful, intractable leg ulcers. One patient had diabetes mellitus type II (DM), the other had vasculitis. Both patients had seen multiple specialists, including a dermatologist, an internist, and a vascular surgeon, but their clinical course continued to worsen. When the pain became intolerable, the patients came to our pain clinic. Chemical lumbar sympathectomy as well as epidural blockade with bupivacaine and morphine were moderately effective in reducing their pain but had no effect on the ulcers. Only after OHT treatments were performed for several months was satisfactory healing observed.

    Fifty patients suffering from chronic venous disease were treated for 30 days with heparan sulphate 100 mg per os, b.i.d., or mesoglycan 50 mg per os, t.i.d., in a single blind random study. Both therapies led to a marked improvement in comparison to basal clinical values, but patients treated with heparan sulphate showed the greatest and most rapid regression of symptoms, associated with a significant improvement in plethysmographic index of capacitance and venous flow. Patients treated with heparan sulphate also showed an increased fibrinolytic activity and a reduced antithrombin III consumption, both of which were statistically significant.

    Full Text Available ABSTRACTThe extract from horse chestnut seeds (Aesculus hippocastanumL., Sapindaceae, standardised for the content of aescin, is used as the treatment for chronic venous insufficiency. It has anti-inflammatory and anti-oedematous properties and indicates a positive effect on the venous tone, rheological properties, and blood coagulability. The mechanism of horse chestnut seed extract/aescin activity was proposed on the basis of in vitro and in vivo studies, and its effectiveness was documented with numerous randomised clinical trials. The results of the studies have proven that horse chestnut seed extract not only significantly improves subjective symptoms in patients with chronic venous insufficiency like calf spasm, leg pain, pruritus, fatigue, but it also reduced leg volume, the ankle and calf circumference. The preparations containing horse chestnut seed extract are very popular and they have similar effectiveness as compression therapy and a preparation with O-(β-hydroxyethyl-rutosides. Moreover, horse chestnut seed extract has been proven to be safe and very well tolerated. The study was to present the results of the studies that have been conducted so far and that have confirmed the effectiveness of use of horse chestnut seed extract or aescin as the treatment for chronic venous insufficiency.

    2013-07-01

    Full Text Available BackgroundIntractable chronic scalp ulcers with cranial bone exposure can occur along the incision after cranioplasty, posing challenges for clinicians. They occur as a result of severe scarring, poor blood circulation of the scalp, and focal osteomyelitis. We successfully repaired these scalp ulcers using a vascularized bipedicled pericranial flap after complete debridement.MethodsSix patients who underwent cranioplasty had chronic ulcers where the cranial bone, with or without the metal plate, was exposed along the incision line. After completely excising the ulcer and the adjacent scar tissue, subgaleal dissection was performed. We removed the osteomyelitic calvarial bone, the exposed metal plate, and granulation tissue. A bipedicled pericranial flap was elevated to cover the defect between the bone graft or prosthesis and the normal cranial bone. It was transposed to the defect site and fixed using an absorbable suture. Scalp flaps were bilaterally advanced after relaxation incisions on the galea, and were closed without tension.ResultsAll the surgical wounds were completely healed with an improved aesthetic outcome, and there were no notable complications during a mean follow-up period of seven months.ConclusionsA bipedicled pericranial flap is vascularized, prompting wound healing without donor site morbidity. This may be an effective modality for treating chronic scalp ulcer accompanied by the exposure of the cranial bone after cranioplasty.

    Full Text Available Stress contributes to a variety of diseases and disorders such as depression and peptic ulcer. The present study aimed to investigate the correlation between stress ulcer and depression in pathogenesis and treatment by using chronic stress depression (CSD, chronic psychological stress ulcer (CPSU and water immersion restrain stress models in rats. Our data showed that the ulcer index of the animals after CSD exposure was significantly higher than that of controls. Depression-like behaviors were observed in rat after CPSU exposure. Fluoxetine hydrochloride significantly reduced the ulcer index of rats exposed to CPSU stress, while ranitidine inhibited depression-like behavior of the animals in CSD group. The ulcer index of rats administered with mifepristone after CPSU stress was markedly reduced compared to CPSU group, although there was no significant difference in the depression-like behavior between mifepristone-treated CSD group and naive controls. We also found that the rats exposed to CPSU or CSD stress displayed a lower level of corticosterone than naive controls, however, the acute stress (AS group showed an opposite result. Additionally, in order to study the relevance of H(2 receptors and depression, we treated the CSD group with cimetidine and famotidine respectively. The data showed that cimetidine inhibited depression-like behavior in CSD rats, and famotidine had no impact on depression. Overall our data suggested that the hypothalamic-pituitary-adrenal (HPA axis dysfunction may be the key role in triggering depression and stress ulcer. Acid-suppressing drugs and antidepressants could be used for treatment of depression and stress ulcer respectively. The occurrence of depression might be inhibited by blocking the central H(2 receptors.

    Full Text Available Abstract Background The potential pathogenesis between the presence and severity of chronic cerebrospinal venous insufficiency (CCSVI and its relation to clinical and imaging outcomes in brain parenchyma of multiple sclerosis (MS patients has not yet been elucidated. The aim of the study was to investigate the relationship between CCSVI, and altered brain parenchyma venous vasculature visibility (VVV on susceptibility-weighted imaging (SWI in patients with MS and in sex- and age-matched healthy controls (HC. Methods 59 MS patients, 41 relapsing-remitting and 18 secondary-progressive, and 33 HC were imaged on a 3T GE scanner using pre- and post-contrast SWI venography. The presence and severity of CCSVI was determined using extra-cranial and trans-cranial Doppler criteria. Apparent total venous volume (ATVV, venous intracranial fraction (VIF and average distance-from-vein (DFV were calculated for various vein mean diameter categories: .9 mm. Results CCSVI criteria were fulfilled in 79.7% of MS patients and 18.2% of HC (p Conclusions MS patients with higher number of venous stenoses, indicative of CCSVI severity, showed significantly decreased venous vasculature in the brain parenchyma. The pathogenesis of these findings has to be further investigated, but they suggest that reduced metabolism and morphological changes of venous vasculature may be taking place in patients with MS.

    Foreign bodies like residues of suture or mesh may lead to a foreign body reaction, cavity formation and continuous secretion and perhaps ulceration. We present a more than 9 years long medical record of a 49 year old man after a simple surgical procedure. The background was a sinus formation gen...... in these cases. The knowledge of the foreign body reaction in tissue continuously needs to be reestablished in the health care system especially in areas, where implantation of foreign material is used....

A total of 75 patients with venous leg ulcers extensively covered with fibrin and necrotic tissue were randomized to a PA-containing hydrogel or an amorphous hydrogel. Wounds were treated for 14 days and costs were estimated from the German payer's perspective. Medical costs included study treatment, wound treatment supply, and labor time. The clinical benefit was expressed as the number of patients with wounds >50% covered with granulation tissue within 14 days. The incremental cost-effectiveness ratio (ICER was expressed as the additional cost spent with >50% granulation tissue per day per patient within 14 days of leg ulcer care.Results: Because of individual pricing of wound dressings in hospitals, cost data were derived from the outpatient sector. A total of 33 patients were treated using the PA-based hydrogel and 37 patients using the amorphous hydrogel. The estimated total direct costs per patient and per 14 days of therapy were €306 for both treatment groups. However, with the PA-based hydrogel, 2.5 additional days with wounds covered >50% with granulation tissues were gained within 14 days of leg ulcer care compared to the comparator. The ICER was €0 per additional day spent with >50% granulation tissue.Conclusion: Although there were a greater number of dressing changes in the PA-based hydrogel treatment, the total treatment cost for 14 days of leg ulcer care was the same for both

    Full Text Available We report a case of chronic herpes simplex in a 27 year old lady presenting with a history of persistent verrucous ulcer in the natal cleft of nine months duration. The patient was diagnosed and treated initially as a case of Tuberculosis Verrucosa Cutis (TVC based on the chronicity of the ulcer, negative HIV serological tests and histopathological findings. The diagnosis had to be revised as the lesion was increasing in size and the patient was not responding to treatment even after completing antituberculous treatment for six months. Repeat histopathological examination and immunohistochemistry showed DNA of herpes simplex. Based on this finding a repeat HIV serology was sent which was positive. The ulcer healed after a course of acyclovir. The case is being reported to highlight the importance of considering chronic herpes simplex infection in a case of chronic genital ulcer. In addition this case reminds us the nature of HIV infection to mislead the diagnosis by altering the natural course of the disease process.

    OBJECTIVE To determine the microbiological profile of diabetes-related foot infections (DRFIs) and the impact of wound duration, inpatient treatment, and chronic kidney disease (CKD). RESEARCH DESIGN AND METHODS Postdebridement microbiological samples were collected from individuals presenting with DRFIs from 1 January 2005 to 31 December 2007. RESULTS A total of 653 specimens were collected from 379 individuals with 36% identifying only one isolate. Of the total isolates, 77% were gram-positive bacteria (staphylococci 43%, streptococci 13%). Methicillin-resistant Staphylococcus aureus (MRSA) was isolated from 23%; risk factors for MRSA included prolonged wound duration (odds ratio 2.31), inpatient management (2.19), and CKD (OR 1.49). Gram-negative infections were more prevalent with inpatient management (P = 0.002) and prolonged wound duration (P < 0.001). Pseudomonal isolates were more common in chronic wounds (P < 0.001). CONCLUSIONS DRFIs are predominantly due to gram-positive aerobes but are usually polymicrobial and increase in complexity with inpatient care and ulcer duration. In the presence of prolonged duration, inpatient management, or CKD, empiric MRSA antibiotic cover should be considered. PMID:19587371

    Solcoseryl, a deproteinized extract of calf blood, protects the gastric mucosa against various topical irritants and enhances the healing of chronic gastric ulcerations but the mechanisms of these effects have been little studied. This study was designed to elucidate the active principle in Solcoseryl and to determine the role of prostaglandins (PG) and polyamines in the antiulcer properties of this agent. Using both, the radioimmunoassay and radioreceptor assay, EGF-like material was detected in Solcoseryl preparation. Solcoseryl given s.c. prevented the formation of stress-induced gastric lesions and this was accompanied by an increase in the generation of PGE2 in the gastric mucosa. Similar effects were obtained with EGF. Pretreatment with indomethacin, to suppress mucosal generation of prostaglandins (PG), greatly augmented stress-induced gastric ulcerations and antagonized the protection exerted by both Solcoseryl and EGF. Solcoseryl, like EGF, enhanced the healing of chronic gastro-duodenal ulcerations. This effect was abolished by the pretreatment with difluoromethylornithine, an inhibitor of ornithine decarboxylase, the key enzyme in the biosynthesis of polyamines. The healing effects of Solcoseryl and EGF was also reduced by prednisolone which decreased the angiogenesis in the granulation tissue in the ulcer area. These results indicate that Solcoseryl 1. contains EGF-like material, 2. displays the protective and ulcer healing effects similar to those of EGF and involving both PG and polyamines and 3. acts via similar mechanism as does EGF.

    We report an unusual case. Our patient had vitiligo, ulcerative colitis, hepatic fibrosis, hypoalbuminemia, bone marrow mastocytosis, a circulating heparinoid and chronic leg ulcers. The relationship between some of the components of this constellation seems logical. This is the case with bone marrow mastocytosis and circulating heparinoid. Also, between hypoalbuminemia and colitis and liver disfunction. On the other hand, the relationship between other features does not seem clear in the light of current knowledge.

    2009-07-01

    We report two patients with chronic tongue ulceration who were successfully treated using sulpiride. The clinical diagnosis was oral candidiasis related to long-term steroid treatment. The results of the culture test and cytological examination supported this diagnosis, but antifungal treatment was ineffective and the tongue pain in these patients became more severe. Furthermore, the pain could not be relieved by nonsteroidal anti-inflammatory drugs (NSAIDs). We therefore prescribed sulpiride in addition to NSAIDs to reduce the tongue pain. A consequent improvement in both pain severity and ulceration was observed 2-3 weeks after sulpiride administration.

    Full Text Available Objective: BIONs™ (BIOnic Neurons are injectable, wireless microstimulators that make chronic BION Active Seating (BAS possible for pressure ulcer prevention (PUP. Neuromuscular electrical stimulation (NMES produces skeletal motion and activates trophic factors, counteracting three major etiological mechanisms leading to pressure ulcers (PUs: immobility, soft-tissue atrophy, and ischemia. Companion papers I and II reviewed prior experience with NMES for PUP, and analyzed the biomechanical considerations, respectively. This paper presents a treatment strategy derived from this analysis, and the clinical results of the first three cases.

    Venous disease of the lower extremities is common but is often misunderstood. It seems that the focus is on the exciting world of arterial anatomy and pathology, while the topic of venous anatomy and pathology comes in second place. However, venous diseases such as chronic venous insufficiency, leg ulcers, and varicose veins affect much of the population and may lead to disability and death. Nurses are often required to answer complex questions from the patients and his or her family about the patient's disease. Patients depend on nurses to provide accurate information in terms they can understand. Therefore it is important to have an understanding of the normal venous system of the legs before one can understand the complexities of venous diseases and treatments. This presents an overview of normal venous anatomy and physiology.

    Social and psychological factors have long been proposed as being of importance in a sizeable subgroup of women complaining of unexplained chronic pelvic pain (CPP). The aim of this study was to examine this in two subgroups of CPP patients, thereby eliminating pain alone as the determining variable. Consecutive attenders at a clinic for CPP were assessed on a range of somatic, historical, social, and psychological variables using detailed interviews and questionnaires. They were subsequently allocated to one of two groups, based on the presence or absence of pelvic venous congestion (PVC). Significant associations emerged between some social arrangements, paternal parenting, and patterns of hostility in the group with pelvic venous congestion. The groups also differed in patterns of family illness, and the congested group tended to report more childhood sexual abuse (CSA). Clear case definition in CPP is important. In the subgroup with pelvic venous congestion early social experience may play an important role. Father-daughter relationships may be particularly relevant. Hostility patterns may influence the development of the condition. CSA does not appear to play a specific role in all unexplained CPP cases, but may have relevance for the subgroup with pelvic venous congestion.

    A randomized controlled trial of Solcoseryl, DuoDerm and conventional conservative therapy with Eusol has been performed in 32 patients with homozygous sickle-cell (SS) disease. After 12 weeks' baseline observation, patients were randomized to one of three therapies and monitored for a further 12 weeks. Of 44 ulcerated legs, 20 received control treatment, 12 Solcoseryl and 12 DuoDerm. DuoDerm was generally unacceptable, and two-thirds of the patients defaulted from this treatment. Solcoseryl increased ulcer healing compared to the controls but the difference was not significant. Solcoseryl was well tolerated and may have a role in the treatment of chronic leg ulcers of sickle-cell disease.

    Histologic, ultrastructural, chemical, and statistical methods were used to study liver biopsy and autopsy specimens from 43 patients who had primary sclerosing cholangitis (PSC), with or without chronic ulcerative colitis (CUC), and from 19 patients who had CUC without PSC. In all study groups, essentially the same abnormalities were found in the hepatic parenchyma outside the major bile ducts, although nondiagnostic tissue samples were observed also. Specimens from patients with extrahepatic PSC were indistinguishable from those patients with combined extra- and intrahepatic PSC. Common findings included periductal fibrosis and inflammation, portal edema and fibrosis, focal proliferation of bile ducts and ductules, focal bile duct obliteration and loss of bile ducts, copper deposition, and cholestasis. Proliferation of bile ducts in some portal tracts and obliteration or absence of bile duct in others were the most characteristic changes. In most specimens, inflammatory changes appeared mild, yet biliary cirrhosis had developed in 34% of the patients. Specimens from patients with PSC, with or without CUC, more often contained bile and strikingly increased stainable copper (Grades 2 and 3) than did specimens from patients with CUC without PSC. Hepatic copper contents, measured by atomic absorption spectrophotometry, also were higher in specimens from patients with PSC. Study of PCS specimens by transmission electron microscopy and by energy-dispersive X-ray microanalysis revealed that most copper was sequestered in lipolysosomes. The recognition of strikingly similar morphologic features in many liver specimens from patients with either PSC or CUC or both suggests that the causes of these conditions are closely related.

    Full Text Available BACKGROUND : Perforator incompetence is an important part of assessment of chronic venous insufficiency ( CVI, but the criteria for perforator incompetence and the relationship with clinical severity is not well established. AIM: To study whether measurement of diameter of perforator correlates with clinical severity of venous insufficiency. MATERIALS AND METHODS: One hundred and forty five consecutive patients ( 168 limbs with varicose veins were evaluated with Doppler study of lower limb veins. Clinical severity and diameter of perforators were assessed. RESULTS: 23% of patients with clinically mild disease had perforator diameter of 3mm or more , whereas , 62% of moderate and severe disease patients had incompetent perforator. Average diameter of perforator in CVI class 1 & 2 patients was 1.44mm whereas , in class 3 & 4 patients , it was 3.31mm and 3.58mm in class 5 & 6 patients. CONCLUSION : Diameter of perforator compare favourably with clinical severity of chronic venous insufficiency. This study may help to evolve patient management guidelines in perforator incompetence treatment

    2017-02-01

    Full Text Available Background/Aims: Chronic leg ulcers (CLUs are globally a major cause of morbidity and mortality with increasing prevalence. Their treatment is highly challenging, and many conservative, surgical or advanced therapies have been suggested, but with little overall efficacy. Since the 1980s extracorporal shock wave therapy (ESWT has gained interest as treatment for specific indications. Here, we report that patients with CLU showed wound healing after ESWT and investigated the underlying molecular mechanisms. Methods: We performed cell proliferation and migration assays, FACS- and Western blot analyses, RT-PCR, and Affymetrix gene expression analyses on human keratinocytes and fibroblasts, and a tube formation assay on human microvascular endothelial cells to assess the impact of shock waves in vitro. In vivo, chronic therapy-refractory leg ulcers were treated with ESWT, and wound healing was assessed. Results: Upon ESWT, we observed morphological changes and increased cell migration of keratinocytes. Cell-cycle regulatory genes were upregulated, and proliferation induced in fibroblasts. This was accompanied by secretion of pro-inflammatory cytokines from keratinocytes, which are known to drive wound healing, and a pro-angiogenic activity of endothelial cells. These observations were transferred “from bench to bedside”, and 60 consecutive patients with 75 CLUs with different pathophysiologies (e.g. venous, mixed arterial-venous, arterial were treated with ESWT. In this setting, 41% of ESWT-treated CLUs showed complete healing, 16% significant improvement, 35% improvement, and 8% of the ulcers did not respond to ESWT. The induction of healing was independent of patient age, duration or size of the ulcer, and the underlying pathophysiology. Conclusions: The efficacy of ESWT needs to be confirmed in controlled trials to implement ESWT as an adjunct to standard therapy or as a stand-alone treatment. Our results suggest that EWST may advance the

  2. Ganoderma Lucidum Pharmacopuncture for Teating Ethanol-induced Chronic Gastric Ulcers in Rats

    2015-03-01

    Full Text Available Objectives: The stomach is a sensitive digestive organ that is susceptible to exogenous pathogens from the diet. In response to such pathogens, the stomach induces oxidative stress, which might be related to the development of both gastric organic disorders such as gastritis, gastric ulcers, and gastric cancer, and functional disorders such as functional dyspepsia. This study was accomplished to investigate the effect of Ganoderma lucidum pharmacopuncture (GLP on chronic gastric ulcers in rats. Methods: The rats were divided into 4 groups of 8 animals each: the normal, the control, the normal saline (NP and the GLP groups. In this study, the modified ethanol gastritis model was used. The rats were administrated 56% ethanol orally every other day. The dose of ethanol was 8 g/kg body weight. The normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated with injection of saline and GLP respectively. The control group received no treatment. Two local acupoints CV12 (中脘 and ST36 (足三里 were used. All laboratory rats underwent treatment for 15 days. On last day, the rats were sacrificed and their stomachs were immediately excised. Results: Ulcers of the gastric mucosa appeared as elongated bands of hemorrhagic lesions parallel to the long axis of the stomach. In the NP and GLP groups, the injuries to the gastric mucosal injuries were not as severe as they were in the control group. Wound healings of the chronic gastric ulcers was promoted by using GLP and significant alterations of the indices in the gastric mucosa were observed. Such protection was demonstrated by gross appearance, histology and immunehistochemistry staining for Bcl-2-associated X (BAX, B-cell lymphoma 2 (Bcl-2 and Transforming growth factor-beta 1 (TGF-β1. Conclusion: These results suggest that GLP at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol induced chronic gastric ulcer.

    Full Text Available BACKGROUND: The role of intra- and extra-cranial venous system impairment in the pathogenesis of various vascular, inflammatory and neurodegenerative neurological disorders, as well as in aging, has not been studied in detail. Nor have risk factors been determined for increased susceptibility of venous pathology in the intra-cranial and extra-cranial veins. The aim of this study was to investigate the association between presence of a newly proposed vascular condition called chronic cerebrospinal venous insufficiency (CCSVI and environmental factors in a large volunteer control group without known central nervous system pathology. METHODS AND FINDINGS: The data were collected in a prospective study from 252 subjects who were screened for medical history as part of the entry criteria and participated in the case-control study of CCSVI prevalence in multiple sclerosis (MS patients, and then were analyzed post-hoc. All participants underwent physical and Doppler sonography examinations, and were assessed with a structured environmental questionnaire. Fullfilment of ≥ 2 positive venous hemodynamic (VH criteria on Doppler sonography was considered indicative of CCSVI diagnosis. Risk and protective factors associated with CCSVI were analyzed using logistic regression analysis. Seventy (27.8% subjects presented with CCSVI diagnosis and 153 (60.7% presented with one or more VH criteria. The presence of heart disease (p = .001, especially heart murmurs (p = .007, a history of infectious mononucleosis (p = .002, and irritable bowel syndrome (p = .005 were associated with more frequent CCSVI diagnosis. Current or previous smoking (p = .029 showed a trend for association with more frequent CCSVI diagnosis, while use of dietary supplements (p = .018 showed a trend for association with less frequent CCSVI diagnosis. CONCLUSIONS: Risk factors for CCSVI differ from established risk factors for peripheral venous diseases. Vascular

  4. Matrix Metalloproteinases as Regulators of Vein Structure and Function: Implications in Chronic Venous Disease.

    Science.gov (United States)

    MacColl, Elisabeth; Khalil, Raouf A

    2015-12-01

    Lower-extremity veins have efficient wall structure and function and competent valves that permit upward movement of deoxygenated blood toward the heart against hydrostatic venous pressure. Matrix metalloproteinases (MMPs) play an important role in maintaining vein wall structure and function. MMPs are zinc-binding endopeptidases secreted as inactive pro-MMPs by fibroblasts, vascular smooth muscle (VSM), and leukocytes. Pro-MMPs are activated by various activators including other MMPs and proteinases. MMPs cause degradation of extracellular matrix (ECM) proteins such as collagen and elastin, and could have additional effects on the endothelium, as well as VSM cell migration, proliferation, Ca(2+) signaling, and contraction. Increased lower-extremity hydrostatic venous pressure is thought to induce hypoxia-inducible factors and other MMP inducers/activators such as extracellular matrix metalloproteinase inducer, prostanoids, chymase, and hormones, leading to increased MMP expression/activity, ECM degradation, VSM relaxation, and venous dilation. Leukocyte infiltration and inflammation of the vein wall cause further increases in MMPs, vein wall dilation, valve degradation, and different clinical stages of chronic venous disease (CVD), including varicose veins (VVs). VVs are characterized by ECM imbalance, incompetent valves, venous reflux, wall dilation, and tortuosity. VVs often show increased MMP levels, but may show no change or decreased levels, depending on the VV region (atrophic regions with little ECM versus hypertrophic regions with abundant ECM) and MMP form (inactive pro-MMP versus active MMP). Management of VVs includes compression stockings, venotonics, and surgical obliteration or removal. Because these approaches do not treat the causes of VVs, alternative methods are being developed. In addition to endogenous tissue inhibitors of MMPs, synthetic MMP inhibitors have been developed, and their effects in the treatment of VVs need to be examined.

  5. Is chronic ulcerative stomatitis a variant of lichen planus, or a distinct disease?

    2017-02-10

    Chronic ulcerative stomatitis is an immune-mediated mucocutaneous disorder characterized clinically by erosions or ulcers. Most cases are limited to the mouth. The histopathological features are non-specific or mimic those of oral lichen planus, and studies by immunoflorescent microscopy are essential for definitive diagnosis. The defining immunopathogenic mechanism is the binding of IgG to the nuclear protein deltaNp63alpha of keratinocytes in the basal and parabasal cell layers of the oral stratified epithelium. DeltaNp63alpha functions as a regulator of epithelial stem cell activity and as an anti-apoptotic agent, and regulates the expression of cell-to-cell and cell-to-basement membrane adhesion molecules. The autoimmune IgG-deltaNp63alpha interaction is thought to result in damage to the structural attachment of keratinocytes to one another and to the epithelial basement membrane zone, and in dysregulation of the cell cycle and apoptosis of basal keratinocytes with the development of erosions or ulcers. The aims of treatment are to suppress the pathogenic immuno-inflammatory responses, to prevent local infection and to promote healing. The purpose of this article is to provide a succinct review of the diagnostic, clinical and aetiopathogenic features of, and treatment guidelines for chronic ulcerative stomatitis, and to argue that this disease should be regarded as a variant of oral lichen planus, rather than as a distinct entity.

    Carrasco, Omar F; Ranero, Alejandra; Hong, Enrique; Vidrio, Horacio

    In segments of human varicose veins, endothelial function was assessed by measuring relaxation induced by acetylcholine in noradrenaline-precontracted preparations. In addition, concentration-response curves to acetylcholine were obtained before and after incubation with the arterial endothelium protectant agents captopril, losartan, troglitazone, pravastatin, or simvastatin. The antivaricose agent escin was also tested. Mean acetylcholine-induced relaxation of varicose venous rings was about 13%, approximately one third of that reported for control saphenous veins. Concentration-response curves to acetylcholine were ''u'' shaped, the result of endothelium-mediated relaxation at low concentrations, superseded by subsequent smooth muscle contractile responses. Relaxation was enhanced by the endothelium-protecting agents and by escin, troglitazone being the least, and simvastatin the most effective. It was concluded that endothelial dysfunction is present in varicose veins, that this anomaly can be reverted by cardiovascular protecting agents, and that it can play a role in the pathogenesis and treatment of chronic venous insufficiency.

    Objective This study was planned and implemented to evaluate the effect of socio-demographic characteristics and clinical findings on the quality of life of patients with chronic venous insufficiency. Methods The sample of this cross-sectional study consisted of 163 patients that presented with the diagnosis of chronic venous insufficiency to the cardiovascular surgery clinic of an education and research hospital in the west of Turkey. The data were collected during face-to-face interviews using a personal information form, clinical, etiology, anatomy, pathophysiology classification, venous insufficiency epidemiological and economic study-quality of life/symptoms scales and the Short Form-36. Descriptive statistics as well as univariate and multivariate analyses were used to analyze the data. Results The chronic venous insufficiency patients were found to have a low quality of life. Advanced age, higher body mass index, longer working times, being on regular medication, hypertension and presence of pigmentation according to the clinical, etiology, anatomy, pathophysiology classification were found to be associated with a reduced physical score in SF-36. Furthermore, longer weekly working hours and presence of pigmentation reduced the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms scores. Undertaking physical exercise at twice and more than twice a week increased the overall physical scores in SF-36. Conclusions The results of the study showed that the quality of life of chronic venous insufficiency patients are affected by not only physical characteristics, working hours and physical activity but also presence of edema and pigmentation.

    Full Text Available We report here a case of Marjolin’s ulcer developing in a long-standing, inadequately treated, chronic ringworm infestation of the lower limb. A 35-year-old female patient with a ten-year history of a chronic ringworm infest­ation had developed a non-healing ulcer in an area of infestation on the right leg. A biopsy revealed well-differentiated squamous cell carcinoma associated with the ringworm infection. A below-knee amputation followedby an inguinal block dissection was performed. We conclude that proper and timely treatment of fungal infections of the skin is needed to allow for healing of dermal infections and thus the prevention of the disastrous consequences. Recurrent mechanical trauma from scratching of the affected area, leading to occult malignancy, may occur in a small number of patients.

    The aim of this study was to evaluate the pharmacodynamics and pharmacokinetics of a single oral dose of Veliten in 12 patients affected by chronic venous insufficiency. In particular, the pharmacokinetics of two components of Veliten, namely rutine and alpha-tocopherol, were considered, while with respect to pharmacodynamics, studies were made of venous function, haemocoagulative and fibrinolytic balance, and haemorheological parameters. Correlation between such changes and plasma drug levels was also evaluated. We found a significant increase of venous tone, venous capacity and venous distension after drug intake, as well as a significant activation of fibrinolysis (globally evaluated with euglobulin lysis time), related to a slight increase of plasminogen tissue activator. These changes appeared concomitantly with maximal plasma levels of rutine. We did not find any modifications of coagulative and haemorheological parameters.

Methods: the questionnaire was translated by a professional translator and two dermatologists specialized in the area of venous ulcers (VU, reformulated in a meeting of the three translators. The construct (VLU-QoL-Br was submitted to pre-interviews with ten VU patients for adaptation of the language. Subsequently, it was applied to patients at the HC-Unesp, and for test-retest reliability for verification of its reproducibility. Results: 82 patients were evaluated, with 56 (68% women. The age average was 67.3 years. The questionnaire was translated, adapted and applied to the patients. The construct presented high internal consistency (alpha = 0.94 and adequate item-total correlation. When the 32 retests were evaluated, an intra-class correlation was noted for concordance of 0.78 (p<0.01, indicating good reproducibility of the construct. The confirmatory factor analysis corroborated the dimensions of the original questionnaire: activities, psychologies, and symptoms. VLU-QoL-Br scores were associated, independently, to the total area of the ulcers and a lower education level of the subjects (p<0.01. Conclusion: the translation, adaptation and validation of the VLU-QoL-Br questionnaire were concluded, demonstrating good psychometric performance, and enabling its clinical use in Brazil. It is important to evaluate its performance in other regions and different samples of individuals.

    Van den Berg, P J; Visser, L H

    2012-03-01

    A new venous disorder, chronic cerebrospinal venous insufficiency (CCSVI), has been proposed in patients with multiple sclerosis (MS). It is a vascular condition characterized by an impaired cerebrospinal venous drainage due to obstructions in the main extracranial cerebrovenous outflow routes (i.e. internal jugular veins [IJV] and/or azygos veins). In this review, the studies which assessed the prevalence of CCSVI in MS by echo colour Doppler (ECD) will be discussed. The technical aspects of determination of the five CCSVI criteria: (1) reflux in the IJV and/or vertebral veins in supine and upright position, (2) reflux in the deep cerebral veins, (3) high-resolution B-mode proximal IJV stenosis, (4) flow not Doppler detectable in IJVs and/or vertebral veins (VVs) and (5) reverted postural control of the main cerebrovenous outflow pathway are described in detail. We conclude that so far there are many studies with contradictory results, and as yet a strong scientific base to support the evidence for a causative relationship of CCSVI and MS is lacking. Recent studies call into question the validity of using ECD as a proper and reliable test for the diagnosis of CCSVI. One explanation for the variety in interpretation of the individual CCSVI criteria, with the wide-ranging percentages CCSVI, could be the different methods by using ECD to determine various criteria.

    Varicose veins are treated at multiple clinical departments, but as patients often visit the dermatology clinic first due to leg ulcers, the present Guidelines for the Management of Lower Leg Ulcers/Varicose Veins were prepared in consideration of the importance of the dermatologist's role. Also, the disease concept of chronic venous insufficiency or chronic venous disorders and the CEAP classification of these disorders are presented. The objective of the present guidelines is to properly guide the diagnosis and treatment of lower leg ulcers/varicose veins by systematically presenting evidence-based recommendations that support clinical decisions.

  15. Biochemical association of metabolic profile and microbiome in chronic pressure ulcer wounds.

    Directory of Open Access Journals (Sweden)

    Mary Cloud B Ammons

    Full Text Available Chronic, non-healing wounds contribute significantly to the suffering of patients with co-morbidities in the clinical population with mild to severely compromised immune systems. Normal wound healing proceeds through a well-described process. However, in chronic wounds this process seems to become dysregulated at the transition between resolution of inflammation and re-epithelialization. Bioburden in the form of colonizing bacteria is a major contributor to the delayed headlining in chronic wounds such as pressure ulcers. However how the microbiome influences the wound metabolic landscape is unknown. Here, we have used a Systems Biology approach to determine the biochemical associations between the taxonomic and metabolomic profiles of wounds colonized by bacteria. Pressure ulcer biopsies were harvested from primary chronic wounds and bisected into top and bottom sections prior to analysis of microbiome by pyrosequencing and analysis of metabolome using 1H nuclear magnetic resonance (NMR spectroscopy. Bacterial taxonomy revealed that wounds were colonized predominantly by three main phyla, but differed significantly at the genus level. While taxonomic profiles demonstrated significant variability between wounds, metabolic profiles shared significant similarity based on the depth of the wound biopsy. Biochemical association between taxonomy and metabolic landscape indicated significant wound-to-wound similarity in metabolite enrichment sets and metabolic pathway impacts, especially with regard to amino acid metabolism. To our knowledge, this is the first demonstration of a statistically robust correlation between bacterial colonization and metabolic landscape within the chronic wound environment.

    Infection with the human immunodeficiency virus (HIV) is still a major health problem world-wide. HIV infection has changed into a chronic infection with the chance of developing long-term complications. Vascular complications are frequently reported in the current literature. HIV and treatment by highly active antiretroviral therapy (HAART) are associated with many cardiovascular risk factors. An increased risk of arterial cardiovascular complications was found in a number of studies. However, data about the risk of venous thrombotic disease (VTE), including potentially fatal conditions as pulmonary embolism, were limited. In a systematic review of the literature, ten relevant epidemiological studies were identified that investigated the risk of venous thrombotic disease in HIV-infected patients. The incidence was increased two- to tenfold in comparison with a healthy population of the same age. However, these studies were mainly retrospective cohort studies that were prone to selection bias, confounding factors were not always mentioned and in all but three control populations were missing. An increased risk of venous thrombotic disease in HIV-infected patients could be explained by the presence of a hypercoagulable state, characterised by an increase in procoagulant factors, such as endothelial TF expression and thrombogenic properties of microparticles, and a decrease in anticoagulant factors, including AT III, HC II and the protein C pathway. Furthermore, the risk of VTE was associated with an increased risk of infections and autoimmune haemolytic anaemia, and was weakly associated with HAART. All together, quite some evidence pointed towards a relationship between HIV infection and venous thrombotic disease, but the association still needs to be established in properly designed epidemiological studies.

    This study was designed to identify the impact chronic ulcerative colitis (UC) has on the lives of patients compared to other chronic conditions. Overall, 451 patients with UC, 309 with rheumatoid arthritis, 305 with asthma, and 305 with migraine headaches were recruited in an Internet survey designed to assess a variety of disease-impact indices. Patients with UC reported a mean of eight (self-defined) flare-ups in the previous 12 months. Significantly more patients with UC (81%) believed that the quantity of flare-ups they experienced was 'normal', compared to patients with migraine headaches (64%) or asthma (75%). Patients with UC also reported significantly more worry about disease complications (84%), depression (62%), and embarrassment (70%) than patients with the other chronic conditions. Compared to patients with other chronic conditions, patients with UC perceive substantially more negative impact upon their lives, especially with regard to the psychological burden.

  19. Bridging the gap between chronic cerebrospinal venous insufficiency and Ménière disease

    Full Text Available Ménière disease (MD is a chronic illness of the inner ear that affects a substantial number of patients every year worldwide. Because of a dearth of well-controlled studies, the medical and surgical management of MD remains quite empirical. The main reason is that it is very difficult to investigate patients affected with Certain MD due to the post-mortem criterion necessary for this diagnostic grade. Although endolymphatic hydrops (EH is the worldwideaccepted mechanism of MD, the causes that induce it are still not clear. In fact MD has been correlated mostly to a wide and different disturbances ranging from trauma to sleep disorders. It is nowadays sufficiently demonstrated that chronic cerebrospinal venous insufficiency (CCSVI is very frequent in MD. Even if CCSVI may potentially induce EH through a pure hydraulic mechanism CCSVI, per se does not explain how the various disorders correlated with MD may interact with CCSVI and provoke EH. The aim of this review is an attempt to approach MD into the context of the more recent findings about the global brain waste clearance system, to which inner ear is anatomically and functionally connected, in order to build a reasonable model of MD pathogenesis. The major part of the diseases correlated to MD may act on the inner ear disturbing the glymphatic (GS and/or brain lymphatic system (BLS activity. The venous system interplays with GS and BLS. In this model CCSVI is considered more than a direct cause of MD rather the anatomical predisposition to develop the disease. In this model EH, and then MD, is the consequence of a failure of the compensation of the congenital venous abnormalities, anatomical compensation as collateral pathways and/or functional compensation as GS and BLS. In this model the major part of the disturbances correlated to MD and the various treatment proposed find their appropriate placement.

    Treatment of chronic diseases in children is a special medical problem. Maintaining constant access to the central vascular system is necessary for long-term hemato-oncological and nephrological therapies as well as parenteral nutrition. Providing such access enables chemotherapic treatment, complete parenteral nutrition, long-term antibiotic therapy, hemodialysis, treatment of intensive care unit patients, monitoring blood pressure in the pulmonary artery and stimulation of heart rate in emergency situations as well as treatment of patients suffering from complications, especially when chances of access into peripheral veins are exhausted. Continuous access to the central vascular system is desirable in the treatment of chronically ill children. Insertion of a central venous catheter line eliminates the unnecessary pain and stress to a child patient accompanying injection into peripheral vessels. In order to gain long-term and secure access to the central venous system, respecting the guidelines of the Center for Disease Control and Prevention contained in the updated 'Guidelines for the Prevention of Intravascular Catheter-Related Infections' is necessary.

Participants VU+ were 36.8% slower on completion of the TUG test (P = .012) and 26.5% slower on completion of the FTSTS test (P = .081). Five-Times-Sit-to-Stand and TUG were strongly correlated with each other, r = 0.93, 0.87, P time to complete FTSTS and TUG increased as a function of comorbidities in the VU+ group; the correlations in the VU- group were not significantly different from zero. The VU+ group exhibited poorer physical performance than the VU- group. The high correlation between FTSTS and TUG and the similarity of correlations with other variables suggest that these physical performance measures may be interchangeable in their ability to predict physical functioning in these clinical groups despite differences in test demands. Clinicians need easy-to-perform reliable clinical tests such as FTSTS and TUG to assess mobility of aging injection users with venous ulcers.

    Full Text Available Venous ulcers (stasis ulcers, varicose ulcers are the wounds occurring due to inappropriate functioning of venous valves, usually of the legs. It is one of the most serious chronic venous insufficiency complications. The overall incidence rate is 0.76% in men and 1.42% in women. When a venous valve gets damaged, it prevents the backflow of blood, which causes pressure in the veins that leads to hypertension and, in turn, venous ulcers. These are mostly along the medial distal leg, which is often very painful, can bleed, and get infected. Treating varicose ulcers is a difficult task to the physician and a nightmare to the suffering patients, though a good number of the treatment principles are mentioned and practiced in allied sciences. In Ayurveda, this condition is considered as dus.t.a vran.a. It can be managed with the specific s′odhana therapy. So, the same treatment protocol was used to treat the case discussed here, i.e. with Nitya virecana and by Basti karma. The wound was successfully treated and, therefore, is discussed in detail.

  5. Cardiovascular and Interventional Radiological Society of Europe commentary on the treatment of chronic cerebrospinal venous insufficiency.

    LENUS (Irish Health Repository)

    Reekers, J A

    2011-02-01

    Chronic cerebrospinal venous insufficiency (CCSVI) is a putative new theory that has been suggested by some to have a direct causative relation with the symptomatology associated with multiple sclerosis (MS) [1]. The core foundation of this theory is that there is abnormal venous drainage from the brain due to outflow obstruction in the draining jugular vein and\\/or azygos veins. This abnormal venous drainage, which is characterised by special ultrasound criteria, called the "venous hemodynamic insufficiency severity score" (VHISS), is said to cause intracerebral flow disturbance or outflow problems that lead to periventricular deposits [2]. In the CCSVI theory, these deposits have a great similarity to the iron deposits seen around the veins in the legs in patients with chronic deep vein thrombosis. Zamboni, who first described this new theory, has promoted balloon dilatation to treat the outflow problems, thereby curing CCSVI and by the same token alleviating MS complaints. However, this theory does not fit into the existing bulk of scientific data concerning the pathophysiology of MS. In contrast, there is increasing worldwide acceptance of CCSVI and the associated balloon dilatation treatment, even though there is no supporting scientific evidence. Furthermore, most of the information we have comes from one source only. The treatment is called "liberation treatment," and the results of the treatment can be watched on YouTube. There are well-documented testimonies by MS patients who have gained improvement in their personal quality of life (QOL) after treatment. However, there are no data available from patients who underwent unsuccessful treatments with which to obtain a more balanced view. The current forum for the reporting of success in treating CCSVI and thus MS seems to be the Internet. At the CIRCE office and the MS Centre in Amsterdam, we receive approximately 10 to 20 inquiries a month about this treatment. In addition, many interventional radiologists

Assessments at wk 6 and during follow-up until 4 mo comprised clinical (CAI) and endoscopic (EI) activity index, histology, quality of life(IBDQ), and laboratory tests.RESULTS: Thirty-five out of thirty-nine patients were qualified for intent-to-treat analysis. After the apheresis treatment at wk 6, 13/35 (37.1%) patients achieved clinical remission and 10/35 (28.6%) patients had endoscopic remission (CAI<4, EI<4). Quality of life (IBDQ) increased significantly (24 points, P<0.01)at wk 6. Apheresis could be performed in all but one patient. Aphereses were well tolerated, only one patient experienced anemia.CONCLUSION: In patients with steroid refractory ulcerative colitis, five aphereses with a granulocyte/monocyte depleting filter show potential short-term efficacy. Tolerability and technical feasibility of the procedure are excellent.

    Necrobiosis lipoidica is a rare granulomatous disorder of the skin. In up to 30% of the affected patients it can lead to ulcerations, which can impair the quality of life and are also very difficult to treat. Its pathogenesis is not fully understood. Only few studies focussing on necrobiosis lipoidica can be found, but none of them focus on ulcerated necrobiosis lipoidica. Therefore, we collected demographic data and comorbidities and assessed treatment options for patients with ulcerated necrobiosis lipoidica. Data of patients who were treated in the wound care centre of the University Hospital of Essen for ulcerated necrobiosis lipoidica over the past 10 years were retrospectively analysed. Hence, data of altogether ten patients (nine women and one man) with ulcerated necrobiosis lipoidica were collected. Of these, 70% of the patients had diabetes mellitus of which 30% had type I diabetes and 40% had type II diabetes; 60% of the patients suffered from arterial hypertension, obesity and hypercholesterolaemia; 40% of the patients suffered from psychiatric disorders such as depression and borderline disorder. Our clinical data demonstrate an association of ulcerated necrobiosis lipoidica and aspects of metabolic syndrome. This leads to a conclusion that ulcerating necrobiosis lipoidica can be seen as part of a generalised inflammatory reaction similar to the inflammatory reaction already known in the pathophysiology of rheumatoid diseases or psoriasis. In patients with clinical atypical painful ulcerations, necrobiosis lipoidica should be considered as a possible differential diagnosis. Therapists should be aware of associated aspects in patients with ulcerated necrobiosis lipoidica who besides diabetes often suffer from other aspects of a metabolic syndrome with increased cardiovascular risk factors. Therefore, these related comorbidities should also be diagnosed and treated.

    Full Text Available Abstract Background Chronic cerebrospinal venous insufficiency (CCSVI has recently been reported to be associated with multiple sclerosis (MS. However, its actual prevalence, possible association with specific MS phenotypes, and potential pathophysiological role are debated. Method We analysed the clinical data of 710 MS patients attending six centres (five Italian and one Canadian. All were submitted to venous Doppler sonography and diagnosed as having or not having CCSVI according to the criteria of Zamboni et al. Results Overall, CCSVI was diagnosed in 86% of the patients, but the frequency varied greatly between the centres. Even greater differences were found when considering singly the five diagnostic criteria proposed by Zamboni et al. Despite these differences, significant associations with clinical data were found, the most striking being age at disease onset (about five years greater in CCSVI-positive patients and clinical severity (mean EDSS score about one point higher in CCSVI-positive patients. Patients with progressive MS were more likely to have CCSVI than those with relapsing-remitting MS. Conclusion The methods for diagnosing CCSVI need to be refined, as the between-centre differences, particularly in single criteria, were excessively high. Despite these discrepancies, the strong associations between CCSVI and MS phenotype suggest that the presence of CCSVI may favour a later development of MS in patients with a lower susceptibility to autoimmune diseases and may increase its severity.

    This 8-week registry study was a comparative evaluation of Pycnogenol (French Maritime Pine Bark extract; Horphag Research, Geneva) and Antistax (grape leaf extract [GLE, Boehringer Ingelheim, Germany]) in controlling symptoms of chronic venous insufficiency (CVI). "Standard management" for CVI is compression; a group of comparable subjects was monitored to evaluate the effects of stockings. The registry included 183 patients (166 completing). Supplementation with Antistax (two tablets of 360 mg/d) or Pycnogenol (100 mg/d) was used. The groups were comparable for age, symptoms, venous incompetence, and microcirculation (with increased capillary filtration and skin flux) at inclusion. At 8 weeks, the rate of swelling (p Pycnogenol (p Pycnogenol (p Pycnogenol. An analog scale quantified symptoms. At 8 weeks, pain and edema were decreased with Pycnogenol and elastic compression (p Pycnogenol (p Pycnogenol was decreased by 40%. Induration was reduced only in the Pycnogenol group (p Pycnogenol were lower (96; 3.3 Euros) in comparison with the other groups (132;1.4 Euros for GLE and 149; 2.2 Euros for compression).

    The Internet is being seen as a growing resource for health-related information for a large number of patients. It is undeniable that its widespread presence has led to the growth of awareness that chronic cerebrospinal venous insufficiency (CCSVI) as an entity that may contribute to the symptoms experienced by patients with multiple sclerosis (MS). Social networking and file-sharing Web sites have brought patients with MS together from all over the world and have facilitated the distribution of personal experiences and information derived from medical research as it relates to CCSVI. As a result, there has been an accelerated growth in the number of patients seeking treatment for this syndrome in light of the possibility that it may improve their present condition. This article will review this phenomenon, the Internet-based resources available to MS patients seeking information about CCSVI, and the responsibilities of physicians as they participate in these online discussions.

    Aescin + essential phospholipids (AEPL) topical gels are used for local treatment of venous and microcirculatory alterations (varicose veins, chronic venous insufficiency). Bruises, swelling, thrombophlebitis, and contusions are effectively treated with AEPL. Active ingredients are escinate and essential phospholipids (EPL). The aim of this new study was the evaluation of the efficacy of the effects of AEPL gel on the microcirculation in subjects with chronic venous insufficiency, venous hypertension (CVH), and venous microangiopathy. Patients were assessed measuring skin flux with laser-Doppler flowmetry (LDF). After 2 weeks of local treatment, all individual values (100%) were significantly decreased (p < 0.05), indicating an improvement in the microcirculation. In all treated patients, flux decreased at least 30% (indicating a decrease in the level of venous microangiopathy) (p < 0.05). Considering these observations, topical treatment with AEPL in areas of venous microangiopathy is beneficial, can prevent ulceration, and improves the skin healing processes.

    A gel including aescin, essential phospholipids (EPL), and heparin (EG) has been used for many years for local treatment of venous, microcirculatory alterations (varicose veins, chronic venous insufficiency). Bruises, swelling, thrombophlebitis, and contusions are effectively treated with this compound. The aim of this study was the evaluation of the efficacy of the effects of an AEPL (aescin+EPL) gel on the microcirculation in subjects with chronic venous insufficiency, venous hypertension (CVH), and venous microangiopathy. Transcutaneous PO(2) was measured at the perimalleolar region. After 2 weeks of treatment, all individual values (100%) were significantly increased (p < 0.05). In all patients, PO(2) increased, indicating a decrease in level of venous microangiopathy. Considering transcutaneous skin PO(2), treatment with AEPL in areas of venous microangiopathy is beneficial in the prevention of ulceration and improves skin healing.

    Background Despite the low incidence of deep vein thrombosis (DVT) in foot and ankle surgery, some authors report a high incidence of symptomatic DVT following Achilles tendon rupture. The purpose of this study was to identify DVT risk factors inherent to Achilles tendon repair to determine which patients may benefit from prophylaxis. Methods One hundred and thirteen patient charts were reviewed following elective and nonelective Achilles tendon repair. For elective repair of insertional or noninsertional Achilles tendinopathy, parameters examined included lateral versus prone positioning and the presence versus absence of a flexor hallucis longus transfer. For nonelective repair, acute Achilles tendon ruptures were compared to chronic Achilles tendon ruptures. Results Of 113 Achilles tendon repairs, 3 venous thromboembolism (VTE) events (2.65%) occurred including 2 pulmonary emboli (1.77%). Seventeen of these repairs were chronic Achilles tendon ruptures, and all 3 VTE events (17.6%) occurred within this subgroup. Elevated body mass index was associated with VTE in patients with chronic Achilles ruptures although this did not reach significance (P = .064). No VTE events were reported after repair of 28 acute tendon ruptures or after 68 elective repairs of tendinopathy. Two patients with misdiagnosed partial Achilles tendon tears were excluded because they experienced a VTE event 3 weeks and 5 weeks after injury, prior to surgery. Conclusion In our retrospective review, chronic Achilles ruptures had a statistically significant higher incidence of VTE compared with acute Achilles ruptures (P = .048) or elective repair (P = .0069). Pharmaceutical anticoagulation may be considered for repair of chronic ruptures. Repair of acute ruptures and elective repair may not warrant routine prophylaxis due to a lower incidence of VTE.

    Arterial blood gas (ABG) analyses have an important role in the assessment and monitoring of the metabolic and oxygen status of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Arterial puncture could have a lot of adverse effects, while sampling of venous blood is simpler and is not so invasive. The aim of this study was to evaluate whether venous blood gas (VBG) values of pH, partial pressure of carbon dioxide (PCO2), partial oxygen pressure (PO2), bicarbonate (HCO3), and venous and arterial blood oxygen saturation (SO2) can reliably predict ABG levels in patients with acute exacerbation of COPD. Forty-seven patients with a prior diagnosis of COPD were included in this prospective study. The patients with acute exacerbation of this disease were examined at the General Hospital EMS Department in Prijepolje. ABG samples were taken immediately after venous sampling, and both were analyzed. The Pearson correlation coefficients between arterial and venous parameters were 0.828, 0.877, 0.599, 0.896 and 0.312 for pH, PCO2, PO2, HCO3 and SO2, respectively. The statistically significant correlation between arterial and venous pH, PCO2 and HCO3, values was found in patients with acute exacerbation of COPD (parterial blood for analysis, venous values of the pH, Pv,CO2 and HCO3 parameters can be an alternative to their arterial equivalents in the interpretation of the metabolic status in patients with acute exacerbation of COPD, while the values of venous Pv,O, and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

    2012-01-01

    Full Text Available The pathophysiology of chronic diabetic ulcers is complex and still incompletely understood, both micro- and macroangiopathy strongly contribute to the development and delayed healing of diabetic wounds, through an impaired tissue feeding and response to ischemia. With adequate treatment, some ulcers may last only weeks; however, many ulcers are difficult to treat and may last months, in certain cases years; 19–35% of ulcers are reported as nonhealing. As no efficient therapy is available, it is a high priority to develop new strategies for treatment of this devastating complication. Because experimental and pathological studies suggest that incretin hormone glucagon-like peptide-1 may improves VEGF generation and promote the upregulation of HIF-1α through a reduction of oxidative stress, the study evaluated the effect of the augmentation of GLP-1, by inhibitors of the dipeptidyl peptidase-4, such as vildagliptin, on angiogenesis process and wound healing in diabetic chronic ulcers. Although elucidation of the pathophysiologic importance of these aspects awaits further confirmations, the present study evidences an additional aspect of how DPP-4 inhibition might contribute to improved ulcer outcome.

    Cardiac tamponade is a rare complication of coronary intervention to chronic total occlusions (CTO PCI). We report a case of persistent bleeding from a venous source following successful anterograde dissection-reentry (ADR) CTO PCI. Pericardiocentesis was performed 1 h post-procedure for tamponade. Persistent bleeding was investigated with contrast transesophageal echocardiography, pericardial manometry and blood analysis. Coronary venography revealed subtle extravasation from a cardiac vein adjacent to the site of luminal re-entry. Coronary venous perforation using ADR CTO PCI has not previously been described; however, the volume of blood loss may be significant and surgical exploration may be appropriate.

    The effect of omeprazole and cimetidine on healing of chronic gastric ulcers and gastric acid secretion was investigated in rats. The effect of three doses of omeprazole given orally once daily for 25 days was investigated. In controls median ulcer healing was 19.6% after 25 days. Omeprazole...... increased median ulcer healing from 36% at 145 mumole/kg/day to 80% at 580 mumole/kg/day. Basal and pentagastrin stimulated gastric acid secretion decreased dose-dependently by nearly 90% at a dose of 580 mumole/kg/day 22-24 hr after the last dose of omeprazole. Cimetidine given twice daily, in a dose...... that initially inhibits gastric acid secretion by 95%, reduced acid secretion by only 50% 11 hr after the last dose. Median ulcer healing after treatment with cimetidine for 25 days was 41%. This study demonstrates that omeprazole has a more long-acting inhibitory effect on gastric acid secretion compared...

    2013-01-01

    Full Text Available Thromboangiitis obliterans (TAO or Buerger's disease is associated with both distal ulcers in the extremities and the possibility of amputation. The only treatment that has been shown to be effective in TAO is complete abstention from smoking. In spite of this, the disease progresses in up to 30 percent of cases and finally results in limb amputation. Only a few pharmacological and surgical options are available to date to improve healing ulcers in TAO. The efficacy of prostaglandin analogues is controversial. This paper summarizes the current evidence for medical treatment with bosentan in chronic ulcers in TAO patients. These available data up to date allow us to conclude that the beneficial effects of bosentan on improving endothelial function, inflammatory processes, and selective vasodilatation of damaged vessels result in a clinical enhancement regarding healing and preventive digital ulcers in such patients. In any case, these promising findings have to be confirmed with larger randomised trials.

    Injection drug users are at high risk for chronic venous disorders (CVD), a condition resulting in a progressive deterioration of venous function of the legs. However, the effects of CVD on walking mobility in this population have not been studied. We examined a causal model of the relationship between injection drug use, CVD, and Walking Mobility. The validity of the Tinetti Balance and Gait scales and walk speed as a composite measure of Walking Mobility was also explored. The participants were 104 men and women from a methadone maintenance treatment center. Drug use included 18 persons who injected drugs only in the hands, arms, and above the waist; 70 who injected all over the body including the lower extremities; and 16 who never injected drugs but used illegal substances by other routes. Forty-nine percent of participants had moderate to severe CVD. Participants were classified into 2 groups according to their history of injection drug use: (a) those who injected in the lower extremities (n = 70) and (b) those who injected in the arms plus those who did not inject (n = 34). All measurements were obtained at baseline and again approximately 6.5 weeks later. Structural equation modeling was used to examine the causal effect of CVD on Walking Mobility. The validity of the Balance and Gait scales and the walk time variable as measures of a Walking Mobility factor was examined using a second-order confirmatory factor analysis. Questionnaires included the Demographic and Health History and Drug History. The lower extremities were evaluated with the clinical portion of the Clinical-Etiology-Anatomy-Pathophysiology classification. Participants completed the Tinetti Balance and Gait test. A timed 6-m walk at the person's normal pace was used to calculate walk speed. Test-retest reliability of the Tinetti Balance and Gait test and walk speed ranged from 0.79 to 0.86. Balance and gait scores were skewed toward the high end of the scale. Walking speed was slow. The leg

    Background Acute exacerbation of chronic obstructive pulmonary disease (COPD) is always associated with a high incidence and mortality. Because of the presence of some concomitant risk factors such as immobilization, bronchial superinfection, patients who are admitted for acute exacerbations of COPD are generally considered to be at moderate risk for the development of venous thromboembolism. In this study, we investigated the prevalence and the clinical manifestations of deep venous thrombosis (DVT) in patients with acute exacerbation of COPD.Methods From March 2007 to March 2009, 520 consecutive patients were included in this study. On admission, color Doppler ultrasound of lower extremities in all cases was performed for diagnosing DVT. Patients with DVT were compared with those without DVT from such aspects as demographics, symptoms, physical signs and risk factors.Results Among the 520 patients, DVT was found in 46 cases (9.7%). In patients with DVT, the duration of hospitalization was longer (P=0.01), and the mechanical ventilation requirement increased (P <0.001). Other indicators for patients with more possibility of DVT were immobility exceeding 3 days (P <0.001); pneumonia as concomitance (P=0.01); respiratory failure type Ⅱ (P=0.013); current smoking (P=0.001). Lower extremity pain was more common in DVT cases in comparison to those without DVT (34.8% vs. 15.2%, P=0.01 ).Conclusions The acute exacerbation of COPD patients, who were immobilized for over 3 days, complicated by pneumonia and had respiratory failure type Ⅱ, had a higher risk of DVT. In addition, DVT detection awareness should be increased in cases that had a lower extremity pain.

    A Marjolin's ulcer refers to malignancies that developed in chronic venous ulcers, scars, or sinuses. We report three-dimensional computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)-CT findings in a patient who developed skin cancer from a chronic leg ulcer. Although rare, on MR, a Marjolin's ulcer should be considered when a well-enhanced soft-tissue mass with a broad based skin ulcer shows a mass effect and invasion of the adjacent bone. CT angiography and PET-CT complement MRI for evaluating the nature of Marjolin's ulcers and may provide essential anatomical information, enabling the physician to design the optimal surgical approach or determining cancer staging.

    The purpose of this study was to investigate the clinical correlation between arterial and venous blood gas (VBG) values in patients presenting to the emergency department (ED) with acute exacerbation of chronic obstructive pulmonary disease. A prospective study of patients with chronic obstructive pulmonary disease presenting to the ED with acute ventilatory compromise was done. Patients were included if their attending physician considered arterial blood gas sampling important in their initial assessment. Data from arterial and venous samples were compared using Spearman correlation and bias plot (Bland-Altman) methods. Ninety-four patients were enrolled in the study. Eighty-nine patients had complete data sets for analysis. Arterial hypercarbia was present in 30 patients (33.7%; range, 51-140.19 mm Hg). All cases of arterial hypercarbia were detected using VBG sampling when a screening cutoff of 45 mm Hg was applied (sensitivity, 100%; 95% confidence interval, 88.7%-100% and specificity, 34%; 95% confidence interval, 23.1%-46.6%). Bias plot revealed moderate agreement between arterial and venous Pco(2) with an average difference of 8.6 mm Hg and 95% limits of agreement of -7.84 to 25.05 mm Hg. For pH, mean difference between each group was 0.039 (range, -0.12 to 0.03). Linear regression analysis for pH demonstrated very close equivalence with a regression coefficient of 0.955, and Spearman correlation showed significant correlation of 0.826 (P = .001). Venous pH and HCO(3) values show excellent correlation with arterial values. Using a previously validated screening cutoff of 45 mm Hg, venous CO(2) has 100% sensitivity in detecting arterial hypercarbia. There is insufficient agreement between venous and arterial CO(2) for VBG to replace arterial blood gas in determining the degree of hypercarbia. Copyright © 2012 Elsevier Inc. All rights reserved.

    O-(beta-hydroxyethyl)-rutosides (HR) is used to treat chronic venous disease and signs and symptoms of chronic venous insufficiency (CVI), varicose veins, and deep venous disease. This independent prospective controlled trial (a registry study) evaluates how the efficacy of HR at the local level (perimalleolar region) can be increased by the administration of a topical HR gel. The study is based on evaluation of microcirculatory variables in patients with severe CVI (ambulatory venous pressure, > 56 mm Hg) and venous microangiopathy. Patients are treated using 1 of the following 3 regimens: oral treatment with 1 g sachets of HR (2 g/d total) plus topical HR 2% gel applied 3 times daily at the internal perimalleolar region; oral treatment only (same dosage), or light elastic compression stockings. Laser Doppler skin flux at rest, skin flux at the perimalleolar region, and transcutaneous PO2 and PCO2 are measured at baseline and at the end of the treatment period. A comparable group of healthy individuals without treatment is observed for 8 weeks. In the treatment groups, flux is increased, PO2 is decreased, and PCO2 is increased compared with normal skin. At 4 and 8 weeks, the improvement in skin flux (which is decreased by all measurements), the increase in PO2, and the decrease in PCO2 (indicating microcirculatory improvement) are statistically significantly greater in the combined oral plus topical treatment group (P < .05). No adverse effects, tolerability problems, or compliance issues are noted. These results indicate an important role of HR in the treatment and control of CVI and venous microangiopathy.

    The aim of the study was to assess the efficacy and safety of opioids in the management of pain in those patients with chronic cutaneous ulcers and breakthrough/incidental pain. An open-label, multicentre, prospective, uncontrolled study was conducted in the pain and ulcer units of 5 hospitals across the Comunidad Valenciana. Eligibility criteria were baseline pain 4 in the visual analogue scale or breakthrough procedural pain 4. Exclusion criteria were cognitive impairment, opioid intolerance, or patient refusal to provide informed consent. The protocol scheduled 5 controls: baseline (enrolment), 15 days, one month, 2 months, and 3 months. The main outcome measure of the study was the visual analogue scale score during rest, movement and procedures. Opioids were administered for release of the baseline pain, and sublingual fentanyl for breakthrough pain. A total of 32 patients (86.5%) completed the study. Baseline pain achieved a mean improvement of 3.6 visual analogue scale points (SD 2.3), movement pain improved by 3.9 points (SD 2.5) and procedural pain improved by 4.5 points (SD 2.8), and the mean pain intensity improvement was statistically significant from the first control and at all controls thereafter (PDolor.

    Full Text Available Helicobacter pylori, the most important cause of gastritis and peptic ulcer, has recently been associated with several extradigestive diseases. The aim of this study was to assess the prevalence of Helicobacter pylori infection and effects of bacterium eradication in 50 patients affected by idiopathic chronic urticaria. Helicobacter pylori was assessed by serology or biopsy and urease test or 13C urea breath test. Amoxicillin, bismuth subcitrate (Denol, metronidazole and cimetidine were given to infected patients for 2 weeks. The results of therapy were assessed by urea breath test six weeks after therapy. In response to treatment urticaria clinically regressed in 16 out of 24 patients (66.6%. Thus bacterium eradication was associated with a remission of urticaria symptoms, suggesting a possible role in the pathogenesis of this disorder.

    The production and implementation of clinical practice guidelines is currently a high political priority and a rapidly developing field within healthcare in the United Kingdom (UK). Their purpose is to provide clinicians with a synthesis of the best available external evidence and operationalize the implementation of evidence-based practice. Despite indications that clinical guidelines can make a difference to the quality of patient care, there is some evidence that practitioners struggle with their application. The aim of this paper is to report one element of a trial undertaken by three collaborating universities in the Northern and Yorkshire Region of the UK health service during 1997-1998. The objective was to understand what makes guidelines acceptable and usable, or otherwise, to health professionals. The findings reported in this paper describe the process of care in those general practices that elected to implement guidelines for the management of patients with venous leg ulcers. We conclude that planning for training, resource and quality improvement processes must be built into a team's guidelines implementation procedures. A preliminary needs analysis of the contextual 'hurdles and levers' within each primary healthcare team is also necessary to identify individual issues that must be addressed if the process is to succeed. These findings provide some lessons for successful implementation of clinical guidelines in general. Recommendations for nursing policy makers, managers, practitioners and researchers are included.

    Full Text Available BACKGROUND This study evaluates the advantage of Negative Pressure Wound Therapy-Vacuum Assisted Closure over Conventional Dressing in the management of chronic non-healing ulcers. METHODS From June 2014 to June 2015, 50 patients were selected (25 cases and 25 controls. After wound debridement, VAC dressing is applied. Pre VAC and post VAC culture and sensitivity is taken. Dressing is given for 72 hours and intermittent suction is given for 10 mins. in an hour, daily for 12 hours with negative pressure ranging from 100 to 125 mmHg. Rest of the time drain of the VAC dressing is connected to the Romovac suction drain. Doppler study to assess the vascularity of the limb before the procedure and X-ray is taken to rule out osteomyelitis. Control group patients are given conventional dressings. RESULTS The gender, age and ulcer distributions were almost equal in the case and control groups and were found to be statistically insignificant. Duration of hospital stay in days was found to be statistically significant between groups. Majority (52% of cases left hospital within 3 weeks’ time, while a major chunk (88% of control population stayed more than 3 weeks. VAC dressing shows better results in patients with normal Doppler study. VAC dressing have better results in patients with 48% undergoing split skin grafting and less rate (8% of amputation as against none undergoing split skin grafting and 24% needing amputation in the control group. Patients with sterile pre-VAC culture were not turning unsterile after VAC, but 90% unsterile turns sterile after VAC. CONCLUSION NPWT is a novel technique for managing an open wound by submitting the wound either to intermittent or continuous subatmospheric pressure. Here, we did a study to study the advantage of vacuum assisted closure over conventional dressing in the management of chronic non-healing ulcers and concluded that VAC decreases hospital stay, improves pus culture sterility, has better result in

    Chronic venous insufficiency (CVI) is a common disease associated with poor quality of life. Genetic polymorphisms causing coagulation abnormalities may account for some of the CVI pathogenesis. Type I plasminogen activator inhibitor (PAI-1) is responsible for fibrinolytic system regulation, and plasma levels of PAI-1 are strongly correlated with PAI-1 4G/5G gene polymorphism. The association between PAI-1 4G/5G gene polymorphism and CVI was investigated. In 34 consecutive patients with clinically overt CVI, the PAI-1 4G/4G polymorphism was detected in three cases (8.8%); the 4G/5G polymorphism was detected in 28 (82.4%). In 34 age- and sex-matched controls, the PAI-1 4G/4G polymorphism was detected in one case (2.9%) and the 4G/5G polymorphism was detected in 14 cases (41.2%). The PAI-1 4G allele was found significantly more frequently in CVI patients than in controls. The 4G allele was associated with a 3.25-fold increase in CVI risk. Thus, a relationship between CVI and the PAI-1 4G allele is apparent.

    Prescription of thromboprophylaxis is not a common practice in pediatric intensive care units. Most thrombi are catheter-related and asymptomatic, without causing acute complications. However, chronic complications of these (a)symptomatic catheter-related thrombi, that is, postthrombotic syndrome (PTS) and residual thrombosis have not been studied. To investigate these complications, critically ill children of 1 tertiary center with percutaneous inserted femoral central venous catheters (FCVCs) were prospectively followed. Symptomatic FCVC-thrombosis occurred in 10 of the 134 children (7.5%; 95% confidence interval [CI], 2.4-9.5). Only FCVC-infection appeared to be independently associated (P=0.001) with FCVC-thrombosis. At follow-up 2 of the 5 survivors diagnosed with symptomatic thrombosis developed mild PTS; one of them had an occluded vein on ultrasonography. A survivor without PTS had a partial occluded vein at follow-up. Asymptomatic FCVC-thrombosis occurred in 3 of the 42 children (7.1%; 95% CI, 0.0-16.7) screened by ultrasonography within 72 hours after catheter removal. At follow-up, mild PTS was present in 6 of the 33 (18.2%; 95% CI, 6.1-30.3) screened children. Partial and total vein occlusion was present in 1 (3%) and 4 (12%) children, respectively. In conclusion, children on pediatric intensive care units are at risk for (a)symptomatic FCVC-thrombosis, especially children with FCVC-infection. Chronic complications of FCVC-thrombosis are common. Therefore, thromboprophylaxis guidelines are warranted in pediatric intensive care units to minimize morbidity as a result of FCVC-thrombosis.

    The recognition of lower extremity venous disease as a significant cause of morbidity and lower quality of life, afflicting up to 25 % of Western populations, has led to rapid and drastic improvements in treatment options as well as an increasing awareness of the disease. Superficial venous disease, a frequent medical problem encountered in clinical practices, is now a common reason for referral to providers offering a spectrum of interventions. Venous guidelines have been set forth by the American Venous Forum and Society for Vascular Surgery covering simple spider veins to chronic venous ulcerations. (Gloviczki et al. J Vas Surg 53:2S-48S, 2011) This review provides an overview of the modern management of varicose veins and venous insufficiency.

  19. Polymicrobial nature of chronic diabetic foot ulcer biofilm infections determined using bacterial tag encoded FLX amplicon pyrosequencing (bTEFAP.

    Scot E Dowd

    Full Text Available BACKGROUND: Diabetic extremity ulcers are associated with chronic infections. Such ulcer infections are too often followed by amputation because there is little or no understanding of the ecology of such infections or how to control or eliminate this type of chronic infection. A primary impediment to the healing of chronic wounds is biofilm phenotype infections. Diabetic foot ulcers are the most common, disabling, and costly complications of diabetes. Here we seek to derive a better understanding of the polymicrobial nature of chronic diabetic extremity ulcer infections. METHODS AND FINDINGS: Using a new bacterial tag encoded FLX amplicon pyrosequencing (bTEFAP approach we have evaluated the bacterial diversity of 40 chronic diabetic foot ulcers from different patients. The most prevalent bacterial genus associated with diabetic chronic wounds was Corynebacterium spp. Findings also show that obligate anaerobes including Bacteroides, Peptoniphilus, Fingoldia, Anaerococcus, and Peptostreptococcus spp. are ubiquitous in diabetic ulcers, comprising a significant portion of the wound biofilm communities. Other major components of the bacterial communities included commonly cultured genera such as Streptococcus, Serratia, Staphylococcus and Enterococcus spp. CONCLUSIONS: In this article, we highlight the patterns of population diversity observed in the samples and introduce preliminary evidence to support the concept of functional equivalent pathogroups (FEP. Here we introduce FEP as consortia of genotypically distinct bacteria that symbiotically produce a pathogenic community. According to this hypothesis, individual members of these communities when they occur alone may not cause disease but when they coaggregate or consort together into a FEP the synergistic effect provides the functional equivalence of well-known pathogens, such as Staphylococcus aureus, giving the biofilm community the factors necessary to maintain chronic biofilm infections

    Determine the qualitative and quantitative composition of the mucosal microflora of oesophagogastroduodenal zone to determine the location of Helicobocter pylori and its place in normomicrobiocenosis and dysbacteriosis in cases of peptic ulcer, chronic gastritis and oesophagitis. Clinical and microbiological studies were conducted in 30 healthy individuals-volunteers, 130 patients with peptic ulcer, 36--chronic gastritis and 24--chronic esophagitis. Helicobacter pylori in 33% of cases included in normomicrobiocenosis of mucosal microflora oesophagogastroduodenal zone, which consists of 12 genera of microorganisms and carries out all protection functions. The recurrence of peptic ulcer disease, exacerbation of chronic active gastritis and oesophagitis are accompanied by a dysbacteriosis of mucosal microflora with overgrowth of typical and atypical microorganisms for normal biotope with reduced occurrenceof Helicobocter pylori. Helicobacter pylori in the biocenosis of mucosal microflora of oesophagogastroduodenal zone is not an infection, has no independent significance in the development of peptic ulcer, chronic gastritis and esophagitis, does not require eradication.

    A 71year old female Caucasian farmer without any known immunosuppression presented with a painful ulcer of her right lower leg after a trauma caused by a wood billet. There was no response to empirical antibacterial treatment. An ulcer biopsy showed an invasive Candida infection of the soft tissue and leucocytoclastic vasculitis. Voriconazole treatment was followed by wound healing. Invasive Candida infection and localized Candida vasculitis represent a rare cause of persisting leg ulcers. The similar clinical picture of chronic venous leg ulcers might blur the true cause and refractory cases should therefore promptly be processed by histopathological diagnostics.

    Background Reducing social distance between hospital staff and patients and establishing clear lines of communication is a major challenge when providing in-patient care for people afflicted by Buruli ulcer (BU) and chronic ulcers. Research on hospitals as therapeutic communities is virtually non-existent in Africa and is currently being called for by medical anthropologists working in the field of health service and policy planning. This paper describes a pioneering attempt to establish a therapeutic community for patients suffering from BU and other chronic ulcers requiring long term hospital care in Benin. Methods A six-month pilot project was undertaken with the objectives of establishing a therapeutic community and evaluating its impact on practitioner and patient relations. The project was designed and implemented by a team of social scientists working in concert with the current and previous director of a hospital serving patients suffering from advanced stage BU and other chronic ulcers. Qualitative research initially investigated patients’ understanding of their illness and its treatment, identified questions patients had about their hospitalization, and ascertained their level of social support. Newly designed question–answer health education sessions were developed. Following these hospital wide education sessions, open forums were held each week to provide an opportunity for patients and hospital staff to express concerns and render sources of discontent transparent. Patient group representatives then met with hospital staff to problem solve issues in a non-confrontational manner. Psychosocial support for individual patients was provided in a second intervention which took the form of drop-in counseling sessions with social scientists trained to serve as therapy facilitators and culture brokers. Results Interviews with patients revealed that most patients had very little information about the identity of their illness and the duration of their

    Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenoses of the internal jugular veins (IJVs) and/or azygos veins and formation of collateral venous channels. A case of a 57-year-old patient with CCSVI in whom the venous outflow from the left IJV to the right atrium occurred through a venous anomaly, the persistent left superior vena cava (PLSVC), is reported. PLSVC is caused by persistence of the left anterior cardinal vein that drains blood from the limb effluent from the left and the left side of head and neck into coronary sinus (Type a), or in the left atrium (Type b). PLSVC can be associated either with innominate vein hypoplasia or other congenital heart abnormalities. Because of evidence of left innominate vein hypoplasia, angioplasty was not performed using the ordinary route but passing with the balloon directly through the PLSVC up to the left IJV. Finally, angioplasty was carried out in a standard manner in the right IJV as well as in the azygous vein. Confirmation angiogram revealed complete reopening of all treated vessels with no evidence of peri- and postoperative complications. The patient was discharged home the following day in good general conditions. PLSVC is a rare congenital vein anomaly but in case of concomitant innominate vein hypoplasia may prove to be a valuable alternative to treat patients with IJV diseases.

    Full Text Available Twenty patients affected by chronic venous disease (CVD in tertiary venous network and/or saphenous vein were analyzed before surgical ablation by echo-color-doppler for the hemodynamic parameters reflux time (RT and resistance index (RI, a negative and a positive prognostic factor, respectively. RT and RI were next correlated with relevant in vitro parameters of venous endothelial cells (VEC obtained from surgical specimens, such as cell migration in response to serum gradient, proliferation index, intercellular adhesion molecule (ICAM-1 and vascular cell adhesion molecule (VCAM-1 expression, as well as cytokines release. Of interest, ICAM-1 expression in patient-derived VEC cultures correlated positively with RT and negatively with RI. Moreover, RT showed a positive correlation with the baseline osteoprotegerin (OPG expression by VEC and an inverse correlation with VEC proliferation index. On the other hand, RI correlated positively with TNF-related apoptosis inducing ligand (TRAIL expression. Among the cytokines released by VEC, GM-CSF showed a positive correlation with VEC proliferation and TRAIL expression and a negative correlation with OPG, ICAM-1 and VCAM-1 expression. Since in vitro recombinant GM-CSF induced VEC proliferation and counteracted the induction of ICAM-1, VCAM-1 and OPG upon exposure to TNF-α, our data suggest an anti-inflammatory activity of GM-CSF on venous endothelial cells.

    Full Text Available Chronic wounds are an economic burden to the patient as they put him out of work and consume quality working days. Local insulin therapy is an innovative method in wound care which accelerates wound healing by increasing angiogenesis and granulation tissue formation. This study aims to evaluate its efficacy. OBJECTIVES: To study the efficacy of topical use of insulin in terms of (1 Rate of wound healing (2 Hospital stay. MATERIALS AND METHODS: This is a prospective study carried out in a tertiary health care center in 46 patients after taking informed and written consent. All patients who were satisfying inclusion and exclusion criteria were randomised into two groups A and B. Local insulin therapy was given to group A and normal saline dressing were done to group B. Size and depth were recorded at the start of the treatment and every week thereafter during the period of study. Strict glycemic control was maintained. Results were compared at complete wound healing or at the end of 8 weeks which was earlier. RESULTS: Improvement of the wound in the form of diameter and depth is seen. Significantly increased proliferation of granulation tissue is noticed in most of the patients belonging to group A, that is who received local insulin therapy. CONCLUSION: Local insulin therapy appears to be an efficacious method in the treatment of chronic diabetic foot ulcers and is safe and effective without any systemic side effects. It significantly reduces the hospital stay

    The Chronic Venous Insufficiency (CVI) of inferior limbs is a widespread disease, with an increasing incidence as a consequence of longer life expectance, life-style, obesity, smoking, use of drugs as oestrogens and progestins and working conditions. Medical therapy is still lacking for evidence of efficacy, and compression therapy is useful only in preventing a worsening of this condition. Surgical treatment is the only radical therapy effective for the advanced phases of the disease. In this context spa balneotherapy can be considered as a possible chance to improve some subjective and objective symptoms of CVI of inferior limbs, and to prevent worsening of this condition. The authors performed a review of the relevant scientific literature concerning the treatment of CVI of inferior limbs with mineral water balneotherapy, in order to evaluate its effects on objective and subjective symptoms and its effectiveness to prevent further worsening. We searched the PubMed/Medline, Cochrane Library, Embase, Web of Science databases for articles published between 1990 and 2011 on this topic. To this end, the authors selected few clinical-controlled and case-controlled studies; patients affected from CVI of inferior limbs were treated with balneotherapy at health spas with sulphureous, sulphate, salsojodic or salsobromojodic mineral waters. Baths in mineral waters were often associated with idromassotherapy and vascular pathway. Effects of spa balneotherapy are related to some aspecific properties, like hydrostatic pressure, osmotic pressure and water temperature, partly related with specific chemico-physical properties of the adopted mineral water. The controlled clinical studies on spa therapy showed significant improvement of subjective (such as itch, paresthesias, pain, heaviness) and objective symptoms (namely edema and skin discromias). These studies suggest that spa balneotherapy may give a good chance of secondary prevention and effective therapy of CVI of inferior

We report three male cousins with chronic foot ulcers, all were affected with late-onset HSAN type 2 (HSAN2). In view of the history of consanguinity and male sex, X-linked recessive transmission was likely in our patients. According to the authors' knowledge this is the first report of HSAN2 from Iran.

    Wound pain is a serious problem for elderly patients suffering from chronic leg ulcers, and it may lead to reduced wound healing rates and reduced quality of life. Biatain-Ibu Non-adhesive (Coloplast A/S), a new pain-reducing moist wound healing dressing containing ibuprofen was tested for pain reduction, safety, and efficacy on 10+2 patients in a single-blinded crossover study against Biatain Non-adhesive (Coloplast A/S). Pain was measured with a Numeric Box Scale before, during, and after dressing change. Quality of life was measured using the World Health Organization-5 Well-Being Index. Dressing moist wound healing properties such as absorption capacity and leakage were tested together with assessment of wound exudate and blood plasma content of ibuprofen. Use of the Biatain-Ibu foam dressing correlated with a decrease in pain intensity scores from 7 in the run-in period to approximately 2.5 in the Biatain-Ibu treatment phase. Quality of life measures were improved which together with the reduced pain could contribute to faster wound healing. The moist wound healing properties of Biatain-Ibu were similar to that of the Biatain Non-adhesive and ulcer size was reduced by 24% during the treatment period. Neither side effects nor systemic plasma concentrations of ibuprofen were observed. These data indicate that Biatain-Ibu could reduce persistent and temporary wound pain, increase Quality of life, was found safe to use, and had excellent moist wound healing properties.

    The association of Helicobacter pylori eradication with the occurrence of renal dysfunction in patients with peptic ulcer diseases is still unclear. This study aimed to clarify the relevance of H. pylori eradication to the occurrence of chronic kidney diseases in patients with peptic ulcer diseases. Data that were available from 2000–2011 were extracted from the National Health Insurance Research Database in Taiwan, and all patients with peptic ulcer diseases (n = 208 196) were screened for eligibility. We divided randomly selected patients into an H. pylori eradication cohort (cohort A, n = 3593) and matched them by age and sex to a without H. pylori eradication cohort (cohort B, n = 3593). Subgroup analysis was further performed for H. pylori eradication within ≤ 90 days of the diagnosis date (early eradication, n = 2837) and within 91–365 days (non-early eradication, n = 756). Cox proportional hazards regression analysis was used to estimate the association of H. pylori eradication with the risk of developing chronic kidney diseases and mortality. We observed that there were more patients suffering from chronic kidney disease in cohort B than in the early eradication subgroup of cohort A (8.49% vs. 6.70%, respectively, p = 0.0075); the mortality rate was also higher in cohort B (4.76% vs. 3.70%, respectively, p = 0.0376). Old age, pulmonary disease, connective tissue disorders, and diabetes were risk factors for chronic kidney diseases but early H. pylori eradication was a protective factor against chronic kidney diseases (hazard ratio: 0.68, 95% confidence interval: 0.52–0.88, p = 0.0030), and death (hazard ratio: 0.69, 95% confidence interval: 0.49–0.96, p = 0.0297). In conclusion, our findings have important implications suggesting that early H. pylori eradication is mandatory since it is associated with a protective role against the occurrence of chronic kidney diseases.

    The present paper presents a hypothesis aimed at explaining why venous leg ulcers, pressure ulcers, and diabetic foot ulcers develop into a chronic state. We propose that the lack of proper wound healing is at least in part caused by inefficient eradication of infecting, opportunistic pathogens......, a situation reminiscent of chronic Pseudomonas aeruginosa infections found in patients suffering from cystic fibrosis (CF). We have analyzed sections from chronic wounds by fluorescence in situ hybridization and found distinct microcolonies-the basal structures of bacterial biofilms. Several researchers have...

  15. Helicobacter pylori virulence factors in duodenal ulceration: A primary cause or a secondary infection causing chronicity

    Reports from countries with a high prevalence of Helicobacter pylori (H pylori) infection do not show a proportionately high prevalence of duodenal ulceration,suggesting the possibility that H pylori cannot be a primary cause of duodenal ulceration. It has been mooted that this discrepancy might be explained by variations in the prevalence of virulence factors in different populations. The aim of this paper is to determine whether the published literature gives support to this possibility. The relevant literature was reviewed and analyzed separately for countries with a high and low prevalence of H pylori infection and virulence factors. Although virulent strains of H pylori were significantly more often present in patients with duodenal ulcer than without the disease in countries with a low prevalence of H pyloriinfection in the population, there was no difference in the prevalence of virulence factors between duodenal ulcer, non- ulcer dyspepsia or normal subjects in many countries, where the prevalence of both H pylori infection and of virulence factors was high.In these countries, the presence of virulence factors was not predictive the clinical outcome. To explain the association between virulence factors and duodenal ulcer in countries where H pylori prevalence is low,only two papers were found that give little support to the usual model proposed, namely that organisms with the virulence factors are more likely than those without them to initiate a duodenal ulcer. We offer an alternative hypothesis that suggests virulence factors are more likely to interfere with the healing of a previously produced ulcer. The presence of virulence factors only correlates with the prevalence of duodenal ulcer in countries where the prevalence of H pylori is low. There is very little evidence that virulence factors initiate duodenal ulceration, but they may be related to failure of the ulcer to heal.

    Chronic cerebrospinal venous insufficiency (CCSVI) is a vascular condition characterized by morphologic alterations involving efferent cerebral vascular paths. CCSVI has been implicated as a contributing factor to multiple sclerosis (MS) but this theory is highly controversial. We report 3 cases of CCSVI patients with MS who had undergone internal jugular veins (IJVs) angioplasty to restore vessels patency. All patients reported significant symptomatic improvement after angioplasty until symptoms recurred after restenosis of the treated IJVs. Surgical IJVs reconstruction was performed. Patients' symptoms gradually improved and the benefits were maintained at the 1-year follow-up.

    Although it is debated whether chronic cerebro-spinal venous insufficiency (CCSVI) plays a role in multiple sclerosis (MS) development, many patients undergo endovascular treatment (ET) of CCSVI. A study is ongoing in Italy to evaluate the clinical outcome of ET. Severe adverse events (AEs) occurred in 15/462 subjects at a variable interval after ET: jugular thrombosis in seven patients, tetraventricular hydrocephalus, stroke, paroxysmal atrial fibrillation, status epilepticus, aspiration pneumonia, hypertension with tachicardia, or bleeding of bedsore in the remaining seven cases. One patient died because of myocardial infarction 10 weeks after ET. The risk of severe AEs related to ET for CCSVI must be carefully considered.

    In the age of multiresistant microbes and the increasing lack of efficient antibiotics, conventional antiseptics play a critical role in the prevention and therapy of wound infections. Recent studies have demonstrated the antiseptic effects of cold atmospheric pressure plasma (APP). In this pilot, study we investigate the overall suitability of one of the first APP sources for wound treatment focusing on its potential antimicrobial effects. The wound closure rate and the bacterial colonisation of the wounds were investigated. Patients suffering from chronic leg ulcers were treated in a clinical controlled monocentric trial with either APP or octenidine (OCT). In patients who presented with more than one ulceration in different locations, one was treated with APP and the other one with OCT. Each group was treated three times a week over a period of two weeks. The antimicrobial efficacy was evaluated immediately after and following two weeks of treatment. Wounds treated with OCT showed a significantly higher microbial reduction (64%) compared to wounds treated with APP (47%) immediately after the treatment. Over two weeks of antiseptic treatment the bacterial density was reduced within the OCT group (-35%) compared to a slight increase in bacterial density in the APP-treated group (+12%). Clinically, there were no signs of delayed wound healing observed in either group and both treatments were well tolerated. The immediate antimicrobial effects of the APP prototype source were almost comparable to OCT without any signs of cytotoxicity. This pilot study is limited by current configurations of the plasma source, where the narrow plasma beam made it difficult to cover larger wound surface areas and in order to avoid untreated areas of the wound bed, smaller wounds were assigned to the APP-treatment group. This limits the significance of AAP-related effects on the wound healing dynamics, as smaller wounds tend to heal faster than larger wounds. However, clinical wound

    Background The influence of inflammatory processes has been one of the hot topics in discussions of the etiology of chronic venous insufficiency(CVI).Erythrocytes are very important in controlling inflammatory immunity and innate immune reactions.The purpose of this study was to analyze the correlation between the development of CVI and the change of CD35,Fy6 on erythrocytes,and interleukin-8(IL-8) levels.Methods A group of 43 patients with CVI were studied in parallel with 8 healthy individuals serving as centrol subjects.Control subjects were those with normal findings on lower extremity duplex examinations.We used an erythrocyte flow cytometer to examine the expression of both CD35 and Fy6 on red blood cells,and an enzyme-linked immunosorbent assay analysis method to measure plasma IL-8 levels.We also analyzed the change of IL-8 levels under the influence of erythrocytes using a modified method of the hemaimmune reaction.Results Compared with normal centrol subjects,CD35 expression increased significantly among patients with CVI classified as C4 without lipodermatosclerosis,but tended to decrease and reach the lowest level among patients classified as C5-C6.Fy6 expression increased significantly among patients in the early stages of CVI,but tended to decrease remarkably among patients classified as C5-C6.The inflammatory response intensified at the C5-C6 classification,where high levels of IL-8 coexisted with a low expression of Fy6.The increase in IL-8 in the CVI group was higher than in the control group in association with the complete blood cells,regardless of the presence of erythrocytes,when inactive tumour cells were added,whereas the level of IL-8 in the CVI group was significantly lower than in the control group.Conclusions Abnormalities of erythrocyte innate immunity represents a fundamental derangement in CVI.These inadequate inflammatory responses may lead to local tissue and microvascular damage of the lower extremity.

    Vascular leg ulcers remain a challenge for the modern health care, and a systematic pathological study on this kind of lesions has not been reported so far. A total of 293 consecutive white patients with chronic leg ulcers (present for a minimum of 6 months and up to several years) referred to the Wound Care Unit (Dermatology, University of Bologna) between March 2008 and June 2011. Thirty-four patients affected by other than vascular ulcers, neoplastic or inflammatory conditions, were excluded. The remaining 259 patients affected by vascular leg ulcers were enrolled in this study. Assessment of the patients general health, skin biopsy, and vascular Doppler of the lower limbs were performed to determine the etiology and to formulate an appropriate management plan, whereas 2 punch biopsies of 3 mm were performed on the border and on the bed of each ulcer. Doppler evaluation showed the presence of vascular hemodynamic impairment in 259 patients. Of these, 181 (69.9%) patients were affected by venous insufficiency, 58 (22.4%) by venous and arterial insufficiency, and 20 (7.7%) by arterial insufficiency. Histopathologic features revealed significant differences, thus, reflecting the clinicopathologic correlation with the underlying hemodynamic impairments. In conclusion, histopathologic and hemodynamic data correlation could provide the basis for future analysis of leg ulcers pathogenesis and may improve treatment protocols. We should underline that this observational study represents a single-institute experience and that larger series are needed to confirm our observations.

Methods Twenty-eight patients (16 women, 12 men, aged 31-89 years) whose venous ulcers had healed and scars formed were included in this study. The echogenicities of scars were measured with a 20 MHz high-frequency ultrasound Dermascan. The thickness of epidermis and dermis was assessed and the number of low echogenic pixels (LEPs) in the papillary dermis and reticular dermis were counted using image analysis software.Results The average epidermal thickness of the scars after 1 week to 20 years of healing was significantly increased compared to those of the control (P<0.01), whereas the average dermal thickness of scars after healing was significantly decreased compared to the control (P<0.01). The numbers of LEPs and the distributions of LEPs between scars and controls had no statistically significant differences. There were no correlations among scar echogenicities, age of healed venous ulcers, initial ulcer areas, age of venous ulcers or age of patients. In the control skin samples, the young group aged 31-69 years had fewer LEPs than did the elderly group aged 70-89 years.Conclusion Our study demonstrates that after the healing of venous leg ulcers

    Complex pressure ulcer wound sites often present with a wide scope of barriers to healing ranging from high colonization of multi-drug-resistant pathogens to tortuous internal anatomy which make the wound recalcitrant to traditional wound care including standard negative pressure wound therapy (NPWT). Negative pressure wound therapy with instillation (NPWTi-d) provides an opportunity to manage and heal wounds with indications not met by standard NPWT such as cavitating wounds with complex undermining and tunneling. In this clinical case report, a patient who presented with a chronic, non-healing Stage IV pressure ulcer underwent a tensor fascia lata flap reconstruction that was complicated by a partial flap-tip nonadherence with associated partial dehiscence of the flap incision that proved unresolvable until application of adjunctive NPWTi-d which allowed the wound to experience a robust rate of granulation, contraction, and closure.

    Full Text Available The aim of the study was to collect results from 366 chronic cerebrospinal venous insufficiency (CCSVI affected patients that were regularly Duplex controlled after having received vein angioplasty following diagnosis for CCSVI. The procedures were all performed in the same Centre and same equipment. The patients were divided into three groups according to the attributed severity of the associated multiple sclerosis: 264 relapse-remitting (RR (72%: 179 females (67.8% and 85 (32.2% males; 62 secondary progressive (17%: 37 (59.7% females and 25 (40.3% males; 40 primary progressive (11%: 22 (55% females and 18 (45% males. A data base revealed eleven most frequent disturbs and symptoms, together with working capacities, and was kept up-todate at every Duplex control aiming to establish a novel rapid CCSVI symptoms questionnaire assessment in 4 years follow up. The symptoms were: diplopia, fatigue, headache, upper limb numbness/mobility, lower limb numbness/mobility, thermic sensibility, bladder control, balance coordination, quality of sleep, vertigo, mind concentration. Results, as follows, appear to be significantly good in the RR group, also the biggest one. Diplopia improved in 262/264 patients (99.2% (P<0.0001; fatigue in 260/264 (98.5% (P<0.0001; headache in 205/208 (98.6% (P<0.0001; balance coordination in 23/26 (88.5% (P<0.0001; quality of sleep in 55/59 (93.2% (P<0.0001; vertigo in 30/33 (90.9% (P<0.0001; mind concentration in 142/144 (98.6% (P<0.0001.

    Eighteen patients with femoral and iliofemoral venous thrombosis were treated surgically. Five of the patients had a moderate degree of venous congestion and were classified as having phlegmasia alba dolens and 13 patients had phlegmasia cerulea dolens. The mean age was 39 years, range 18-60 years; 6 were men and 12 women. Thrombectomy was performed with a Fogarty venous thrombectomy catheter. In all cases the thrombosis was verified by phlebography. Pre- and postoperative phlebography was used in all cases to show the patency of the femoral and iliofemoral segment. There was no operative pulmonary embolism or mortality. Heparin infusion was continued in the thrombectomized segment for 10 days followed by phenprocumone treatment. The patients were followed from 6 to 8 months, postoperatively. The operation was performed in the acute stage and the late results are as follows: 4 limbs good, 6 limbs fair and 8 limbs poor. The best results were obtained when the latency period was 24 to 72 hours. Postthrombotic sequelae could not be prevented in about 44% of all patients despite venous thrombectomy.

    Results: Utilization of laser dosage (energy density of 40 J/cm2 and 1.6 w/cm2 power density of the wavelength 820 nm and 30 J/cm2 energy density and power density of 0.24 w/cm2 of 780 nm wavelength, in addition to energy density of 8 J/cm2 and power density of 0.24 w/cm2 and 0.40 w/cm2 and energy density of 1.6 J/cm2 for the 675 wavelength was applied. In this study, we used the bio-stimulation effect of LLLT to enhance healing through immune modulation. However, the application of low level diode laser in the treatment of diabetic wounds can be accompanied by low energy density and short wavelength to give better results in a short time and a good diagnostic accuracy for its potentiality in the field. Conclusions: Consequently, the brown skins in Sub-Saharan region for different tissues of Sudanese diabetic patients of chronic skin ulcer can be treated with different wavelengths and energy relative to tissues softening and laser parameters of that optimum values were obtained. The assessment of skin regeneration using laser therapy expose that the quality of growth, the reasonable period of healing and decreases the risk skin infection were achieved. The process of diabetic wounds curing and de-pigmentation, potential resident of decreasing pain and an efficient adjunct to a standard wound management was obtained.

    Full Text Available Efraim Jaul Skilled Geriatric Nursing Department, Herzog Memorial Hospital, Affiliated to the Hebrew University Hadassah Medical School, Jerusalem, Israel Abstract: The occurrence of pressure ulcers (PUs is common and poses serious problems for the frail elderly, with implications for functional disability and reduced quality of life. PUs are preventable in a majority of cases. The increase in PU occurrence, however, appears regardless of higher awareness in prevention and improvement through utilization of pressure relieving devices. Multiple changes in the elderly body systems occur over time including aging, multiple chronic conditions, and functional impairment, potentially culminating in the final pathways of geriatric syndrome, unless awareness to the development of PUs is reversible and prevented. The assumption is that the development of PUs is based on multifactorial causes (extrinsic and intrinsic factors; thus, the optimal management for elderly patients requires a comprehensive approach in all medical settings (community, hospital, and at the long term care [LTC] level. Comprehensiveness signifies looking beyond the wounds, assisting the patient through both local (wound and systemic (medical condition treatment, using a strategy of prevention and supporting quality of life. Within the multidisciplinary involvement team approach, each professional discipline contributes its own task in coordination with other disciplines to address PU prevention, assessment, and treatment. The entire medical staff and the multidisciplinary team work together and communicate frequently in order to prevent, halt at an early stage, and provide healing in a timely fashion. Limiting the formation of PUs is facilitated through early identification, treating contributing causes, eliminating all unnecessary medications, instituting supportive interventions which include the family.

    Full Text Available Background:Venous insufficiency is a very prevalent disease. Some decades ago a group of patients was identified that had symptoms of venous insufficiency, but no visible anatomic abnormalities. Studies showed that this subset had reduced venous tone, and their condition became known as hypotonic phlebopathy.Objective:To investigate prevalence, age group and variations in body mass index (BMI among patients with hypotonic phlebopathy.Methodology:A total of 1,960 limbs were examined in 1,017 patients who had been referred for complaints compatible with venous insufficiency. Patients with BMI ≥ 30 were defined as obese. The patients were examined using color Doppler ultrasonography to detect presence or absence of reflux in veins of the lower limbs and were then distributed into two groups as follows: patients with CEAP ≤ 1 and no reflux, diagnosed with hypotonic phlebopathy; or patients with CEAP ≥ 2 and reflux.Results:The study sample comprised 89.7% women and 10.3% men with a mean age of 44.9 years. Hypotonic phlebopathy was more common among the women (p = 0.0001. Obese women were more likely than women who were not obese to have venous symptom etiology involving trunk lesions (p = 0.0017. Among the men, obesity was unrelated to etiology of symptoms (p = 0.5991. Symptomology was more likely to be related to trunk vein damage among older age groups than among younger age groups (p-valor <0.0001.Conclusions:Hypotonic phlebopathy was very prevalent, particularly among young women who were not obese.

    Chronic venous disease, reviewed herein, is manifested by a spectrum of signs and symptoms, including cosmetic spider veins, asymptomatic varicosities, large painful varicose veins, edema, hyperpigmentation and lipodermatosclerosis of skin, and ulceration. However, there is no definitive stepwise progression from spider veins to ulcers and, in fact, severe skin complications of varicose veins, even when extensive, are not guaranteed. Treatment options range from conservative (eg, medications, compression stockings, lifestyle changes) to minimally invasive (eg, sclerotherapy or endoluminal ablation), invasive (surgical techniques), and hybrid (combination of ≥1 therapies). Ms L, a 68-year-old woman with varicose veins, is presented. She has had vein problems over the course of her life. Her varicose veins recurred after initial treatment, and she is now seeking guidance regarding her current treatment options.

The MS duration values stratified by EDSS grouped values in CCSVItype- 1 and CCSVI-type-3 patients shows that the differences were statistical significant by Kruskal-Wallis test: H=44.2829; degree of freedom= 1 for CCSVI-type-1 (P<0.001; and H=37.3036; degree of freedom=1 for CCSVItype- 3 (P<0.001. The present study confirmed and completed scientific literature about relation between CCSVI and MS. On the same time, we found a strong correlation between MS illness duration and severity of EDSS score. In fact there is a clinical severity worsening after 11 years of illness in MS patients with CCSVI type-1 or type-3 (P<0.001. These data may suggest the influence of chronic vascular disease on MS. Further searches need in order to learn more about this new aspect in

    Patients with postthrombotic syndrome due to previous femoral-popliteal deep venous thrombosis often experience lifestyle-limiting lower-extremity pain and swelling. Conservative treatment options include compression stockings and lymphedema massage, but in many cases these treatments only temporarily and partially improve symptoms. Ultrasound and venography in patients with postthrombotic syndrome often show only partial recanalization of the femoral vein with significant collateral vein formation. These abnormal veins are insufficient for adequate venous drainage from the lower extremity as evidenced by the patient's continued symptoms. Recanalization of the occluded or partially occluded femoral vein using prolonged venoplasty, with or without chemical thrombolysis, combined with optimizing anticoagulation and conservative treatment measures, results in lasting improvement in symptoms for a high percentage of patients.

    Thymol, a monoterpene phenol derivative of cymene, is found in abundance in the essential oils of Thymus, Origanum, and Lippia species. The present study investigated the gastroprotective actions of thymol (10, 30, and 100 mg/kg, p.o.) in the acute (ethanol- and nonsteroidal anti-inflammatory drug-induced ulcers) and chronic (acetic acid-induced ulcers) ulcer models in rats. Some of the mechanisms underlying to the gastroprotective effect of thymol were investigated in the ethanol-induced ulcer model. Gastric secretion parameters (volume, pH, and total acidity) were also evaluated by the pylorus ligature model, and the mucus in the gastric content was determined. The anti-Helicobacter pylori activity of thymol was performed using the agar-well diffusion method. Thymol (10, 30, and 100 mg/kg) produced dose dependent reduction (P ulcer model. The gastroprotective response caused by thymol (30 mg/kg) was significantly attenuated (P ulcer index (P ulcer models, respectively. In the model pylorus ligature, the treatment with thymol failed to significantly change the gastric secretion parameters. However, after treatment with thymol (30 and 100 mg/kg), there was a significant increase (P ulcer models through mechanisms that involve increased in the amount of mucus, prostaglandins, and ATP-sensitive K(+) channels.

    The aim of this study was to describe the epidemiology of chronic wounds in a large cohort of patients from a tertiary hospital out-patient clinic, and examine the significance of serum mannan-binding lectin for the occurrence and clinical presentation of such wounds. The study comprised 489...... consecutive patients with chronic foot and leg ulcers. A clinical classification of wound- aetiology was performed, and mannan-binding lectin was measured in the sera of patients and healthy controls. The patients presented with 639 wounds altogether; diabetic foot ulcers (309), venous leg ulcers (188......), arterial ulcers (109), and vasculitis (33). The mannan-binding lectin levels of patients with venous leg ulcer, alone or in combination with other types of wounds, differed significantly from the control group, and the frequency of values

    AIM: To compare Helicobacter pyloriinfection and gastric mucosal histological features of gastric ulcer patients with chronic gastritis patients in different age groups and from different biopsy sites.METHODS: The biopsy specimens were taken from the antrum, corpus and upper angulus of gastric ulcer and chronic gastritis patients. Giemsa staining, improved Toluidine-blue staining and H pylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylineosin staining was used for the histological diagnosis of activity of H pylori infection, mucosal inflammation,glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney System.RESULTS: Total rate of H pylori infection, mucosal inflammation, activity of H pylori infection, glandular atrophy and intestinal metaplasia in 3 839 gastric ulcer patients (78.5%, 97.4%, 82.1%, 61.1% and 64.2%,respectively) were significantly higher than those in 4 102chronic gastritis patients (55.0%, 90.3%, 56.2%, 36.8%,and 37.0%, respectively, P<0.05). The rate of H pylori colonization of chronic gastritis in <30 years, 31-40 years,41-50 years, 51-60 years, 61-70 years and >70 years age groups in antrum was 33.3%, 41.7%, 53.6%, 57.3%,50.7%, 43.5%, respectively; in corpus, it was 32.6%,41.9%, 53.8%, 60.2%, 58.0%, 54.8%, respectively; in angulus, it was 32.4%, 42.1%, 51.6%, 54.5%, 49.7%,43.5%, respectively. The rate of Hpyloricolonization of gastric ulcer in <30 years, 31-40 years, 41-50 years,51-60 years, 61-70 years and >70 years age groups in antrum was 60.5%, 79.9%, 80.9%, 66.8%, 59.6%, 45.6%,respectively; in corpus, it was 59.7%, 79.6%, 83.6%,80.1%, 70.6%, 59.1%, respectively; in angulus, it was61.3%, 77.8%, 75.3%, 68.8%, 59.7%, 45.8%,respectively. The rate of H pylori colonization at antrum was similar to corpus and angulus in patients, below50 years, with chronic gastritis and in patients, below40 years, with

    AIM:Pouchitis develops in ileoanal pouches in up to 50% of patients with ulcerative colitis during the first 10years after pouch surgery while being rare in patients after proctocolectomy for familial adenomatous polyposis coii (FAP) syndrome. Defensins are major components of the innate immune system and play a significant role in gastrointestinal microbial homeostasis. Pouch defensin and cytokine expression were correlated with states of pouch inflammation to study their role in pouchitis.METHODS:Patients with ulcerative colitis and FAP syndrome were stratified into groups with pouches after surgery, pouches without or with pouchitis. Biopsies from terminal ileum from a healthy intestine or from normal terminal ileum of patients with ulcerative colitis served as controls, mRNA from pouches and controls was analysed for defensin and cytokine expression.RESULTS: Expression of defensins was increased in all pouches immediately after surgery, compared to ileum of controls. Initially, pouches in ulcerative colitis revealed higher defensin expression than FAP pouches. Defensin expression declined in both patient groups and increased again slightly in pouchitis in patients with ulcerative colitis. FAP pouches without pouchitis had strong expression of β-defensin hBD-1, while all other defensins remained at low levels. Cytokine expression in ulcerative colitis pouches was high, while FAP pouches showed moderately elevated cytokines only after surgery.CONCLUSION: Development of pouchitis correlates with decreased defensin expression in ulcerative colitis in addition to high expression of cytokines. The low incidence of pouchitis in FAP pouches correlates with increased expression of hBD-1 β- defensin in association with low cytokine levels.

    Chronic atrophic gastritis (CAG) is closely correlated with gastric cancer and is predominant in Japan. Epidemiologically, food habits are the primary factor in both CAG and gastric cancer. Two potential serum markers for CAG have recently been investigated, i.e., the concentration of serum pepsinogen (PG) and the presence of serum antibodies against Helicobacter pylori. Serum PG I and II and the PG I:PG II ratio have been reported to be useful as indicators of recurrent peptic ulcer and for screening of patients at risk from gastric cancer. In this study, we examined PG I and II in serum from 483 patients by RIA (DAINABOT), and endoscopic examination performed in the same patients before serological assay revealed CAG in 68, peptic ulcer in 91, and gastric cancer in 48. Analysis of the mean values according to patients age showed that CAG patients in their forties to eighties had low ( or = 70 ng/ml) levels, except for those in their seventies, and gastric cancer patients in their twenties to sixties had low (< 3.0) PG I:PG II ratios, except for those in their sixties. Thus serum PG assay has potential utility for detection of CAG, peptic ulcer, and gastric cancer.

    BACKGROUND: The aim of our study was to quantitatively compare the changes and correlations between pulmonary venous flow variables and mean left atrial pressure (mLAP) under different loading conditions in animals with chronic mitral regurgitation (MR) and without MR. METHODS: A total of 85 hemodynamic conditions were studied in 22 sheep, 12 without MR as control (NO-MR group) and 10 with MR (MR group). We obtained pulmonary venous flow systolic velocity (Sv) and diastolic velocity (Dv), Sv and Dv time integrals, their ratios (Sv/Dv and Sv/Dv time integral), mLAP, left ventricular end-diastolic pressure, and MR stroke volume. We also measured left atrial a, x, v, and y pressures and calculated the difference between v and y pressures. RESULTS: Average MR stroke volume was 10.6 +/- 4.3 mL/beat. There were good correlations between Sv (r = -0.64 and r = -0.59, P pressure in the MR and NO-MR groups. In velocity variables, Sv (r = -0.79, P <.001) was the best predictor of mLAP in both groups. The sensitivity and specificity of Sv = 0 in predicting mLAP 15 mm Hg or greater were 86% and 85%, respectively. CONCLUSION: Pulmonary venous flow variables correlated well with mLAP under altered loading conditions in the MR and NO-MR groups. They may be applied clinically as substitutes for invasively acquired indexes of mLAP to assess left atrial and left ventricular functional status.

    Full Text Available Introduction: Diabetic foot ulcers accounts for many hospital admissions and it is also a major cause of amputations. More importantly it is preventable by effective identification, education and preventive foot care practice. Therefore, lifestyle modification remains a cornerstone of management.Objective: Determine the level of knowledge and practice of foot care among patients with chronic diabetic foot ulcers.Methodology: Individuals having diagnosed diabetic foot ulcers (n=110 were selected from National Hospital of Sri Lanka(NHSL for this descriptive cross sectional study. They were given an interviewer administered, pre tested questionnaire following informed consent. Patient perceptions of foot care were inquired. A scoring system ranging from 0-10 was employed to analyze the responses given for level of knowledge and practice of diabetic foot care. The study was approved by the Ethics Review Committees of Faculty of Medicine, Colombo.Results: Mean age was 58.4 years( SD ±8.6 and 57.3% were males. Non healing ulcers were present among 82.7% and amputations amounted to 38.2%. The control of diabetes was poor in 60%. Regarding foot care knowledge, the mean score was 8.37, 75.5% had scored above mean and 52.7% were aware of all principles of foot care. Regarding foot care practices, the mean score was 4.55, 47.3% participants had scored below mean and 22.7% did not practice any foot care principle and hence scored 0. A Statistically significant difference exists between the foot care knowledge and practice scores (p<0.001, z= -8.151. In the study sample 51% were not educated prior to occurrence of complications.Conclusion: Results demonstrate a satisfactory knowledge on diabetic foot disease, however their practices of preventive techniques were unsatisfactory. Implementation of a national policy on diabetic foot management and good patient follow-up to increase compliance would help to improve this situation.

    The aim of the study is to evaluate the clinical and X-ray results of the Upper Cervical Chiropractic care through the specific adjustments (corrections) of C1-C2 on patients with chronic venous cerebral-spinal insufficiency (CCSVI) and multiple sclerosis (MS). We studied a sample of 77 patients before and after the Upper Cervical Chiropractic care, and we analyzed: A) The change of the X-ray parameters; B) The clinical results using a new set of questions. The protocol of the C1- C2 upper Cervical Chiropractic treatment, specific for these patients, lasts four months. From a haemodynamic point of view we divided the patients in 3 types: Type 1 - purely vascular with intravenous alterations; Type 2 - "mechanical" with of external venous compressions; Type 3 - mixed. We found an improvement in all kinds of subluxations after the treatment with respect to the pre-treatment X-ray evaluation, with a significant statistical difference. The differences between the clinical symptoms before and after the specific treatment of C1-C2 are statistically significant with pcerebro-spinal fluid.

    Full Text Available Graduated compression devices are considered the standard care for management of venous and lymphatic disorders. Recently compression devices exerting a pressure over the calf higher than over the ankle have been proved to be more effective than traditional graduated devices in increasing the impaired ejection fraction (EF from the lower leg in patients with venous disease. Aim of this work is presenting an overview of the new concept on progressive compression, its potential benefits and limits. In different series of tests, the EF from the lower leg was assessed in 70 patients with severe reflux in the great saphenous vein (GSV. EF was measured by strain gauge plethysmography, in baseline conditions and after applying graduated compression devices or the new inversely graduated or progressive compression (PC devices. The interface pressure was recorded, simultaneously with the EF, both in the gaiter area (B1 point and at the calf (C point in order to assess the compression pressure profile. EF, severely impaired in patients with GSV reflux, was increased by compression. So called PC devices (both PC elastic stocking and PC inelastic bandages were significantly more effective than graduated compression in increasing the ejection fraction. The higher the pressure on the calf the higher the EF improvement. Maintaining the same strong pressure over the calf by means of two progressive stockings and increasing the pressure only over the calf to restore a graduated compression didn’t improve the EF. To improve venous pumping function in the ambulant patient stronger compression of the calf is more effective than graduated compression. This can be explained by the higher amount of blood volume pooled in the calf veins.

    Venous leg ulceration represents a global health problem affecting predominantly elderly women. Traditionally, functional problems in this group of patients have attracted modest attention from wound care providers and physiotherapists. The aim of the present study was to describe and quantify disease consequences in female leg ulcer patients as a background for future physiotherapy interventions, using the nomenclature of the WHO International Classification of Functioning, Disability and Health (ICF). A prospective study was conducted in 34 women aged 60-85 years with current or previous venous leg ulcer as compared to 27 age-matched non-ulcer subjects. The outcome variables were pain, ankle range of motion, walking speed, walking endurance, self-perceived exertion, mobility, activities of daily living (ADL), physical activity, general health, life satisfaction and use of walking aids and community services. Established instruments were utilized and categorized within ICF domains to provide a conceptual framework and basis for physiotherapeutic research. Leg ulcer patients showed significantly reduced values of ankle range of motion, walking speed and endurance, self-perceived exertion, mobility, ADL and physical activity level as compared to control subjects. Patients suffering from active ulceration were more negatively affected, and more of them had pain than post-ulcer fellows. By contrast, general health and life satisfaction were similarly rated by the two study groups. Elderly females in our study with chronic leg ulcer of venous aetiology had significant mobility impairments, but the reasons and consequences of these impairments remain to be elucidated. The potential of preventive measures and physical rehabilitation to aid functioning and prospects of leg ulcer repair need to be investigated in future studies.

    Several studies have demonstrated the effective antithrombotic action of mesoglycan to treat chronic venous disease (CVD). The study aimed to assess clinical and quality of life (QoL) (CIVIQ 20 questionnaire) improvements in mesoglycan-treated patients with clinical, etiological, anatomical and pathophysiological (CEAP) stages 2 and 3. The open, multicentre, uncontrolled, observational, prospective study involved treating patients with 50 mg x 2/day mesoglycan for 2 months and measuring improvement to lower-limb edema and QoL in the Global, Physical, Pain, Psychological, and Social Dimensions of the Chronic Venous Disease Quality-of-Life Questionnaire (CIVIQ 20) at the first, baseline visit (V1), at the end of treatment (V2) and 2 (V3) and 4 months after treatment completion (V4). At the last visit (V4), patient disease status was assessed objectively (by the treating physician) and subjectively (by the patient). The study population was divided into three groups: 1) patients with only varicose veins; 2) patients with only lower-limb edema; 3) patients with varicose veins and edema (ITT population). Seventy-five centers enrolled 1066 patients (ITT population); 914 patients completed the study. Mesoglycan treatment produced significant improvement of edema and lower-limb circumference at every visit, in both patients with edema alone and those with edema and varicose veins (paired sample t-test Pmesoglycan treatment to improve QoL significantly in patients with CVD as measured by a specific questionnaire like the CIVIQ 20. The extent of average edema reduction observed at the last visit (4 months after the end of drug treatment), suggests mesoglycan might have an etiological role, modifying the physiological factors underlying CVD and not just affording temporary improvement of symptoms.

    Introduction Lower limb venous disease affects up to one half, and obesity up to one quarter, of the adult population. Many people are therefore affected by, and present to health services for the treatment of both conditions. This article reviews the available evidence of pathophysiological and clinical relationship between obesity and varicose veins, chronic venous insufficiency and ulceration and deep vein thrombosis. Methods A literature search of PubMed and Cochrane libraries was performed in accordance with PRISMA statement from 1946 to 2015, with further article identification from following cited references for articles examining the relationship between obesity and venous disease. Search terms included obesity, overweight, thrombosis, varicose veins, CEAP, chronic venous insufficiency, treatment, endovenous, endothermal, sclerotherapy, bariatric surgery and deep vein thrombosis. Results The proportion of the population suffering from lower limb venous disease and obesity is increasing. Obesity is an important risk factor for all types of lower limb venous disease, and obese patients with lower limb venous disease are more likely to be symptomatic as a result of their lower limb venous disease. The clinical diagnosis, investigation, imaging and treatment of lower limb venous disease in obese people present a number of challenges. The evidence base underpinning medical, surgical and endovenous management of lower limb venous disease in obese people is limited and such treatment may be associated with worse outcomes and increased risks when compared to patients with a normal body mass index. Conclusion Lower limb venous disease and obesity are both increasingly common. As such, phlebologists will be treating ever greater numbers of obese patients with lower limb venous disease, and clinicians in many other specialties are going to be treating a wide range of obesity-related health problems in people with or at risk of lower limb venous disease.

    Chronic wounds including diabetic foot ulcers, pressure ulcers, and venous leg ulcers are a worldwide health problem. It has been speculated that bacteria colonizing chronic wounds exist as highly persistent biofilm communities. This research examined chronic and acute wounds for biofilms and characterized microorganisms inhabiting these wounds. Chronic wound specimens were obtained from 77 subjects and acute wound specimens were obtained from 16 subjects. Culture data were collected using standard clinical techniques. Light and scanning electron microscopy techniques were used to analyze 50 of the chronic wound specimens and the 16 acute wound specimens. Molecular analyses were performed on the remaining 27 chronic wound specimens using denaturing gradient gel electrophoresis and sequence analysis. Of the 50 chronic wound specimens evaluated by microscopy, 30 were characterized as containing biofilm (60%), whereas only one of the 16 acute wound specimens was characterized as containing biofilm (6%). This was a statistically significant difference (p<0.001). Molecular analyses of chronic wound specimens revealed diverse polymicrobial communities and the presence of bacteria, including strictly anaerobic bacteria, not revealed by culture. Bacterial biofilm prevalence in specimens from chronic wounds relative to acute wounds observed in this study provides evidence that biofilms may be abundant in chronic wounds.

    Non-healing chronic wounds present a major biological, psychological, social, and financial burden on both individual patients and the broader health system. Pathologically extensive inflammation plays a major role in the disruption of the normal healing cascade. The causes of chronic wounds (venous, arterial, pressure, and diabetic ulcers) can be examined through a juxtaposition of normal healing and the rogue inflammatory response created by the common components within chronic wounds (ageing, hypoxia, ischaemia-reperfusion injury, and bacterial colonisation). Wound bed care through debridement, dressings, and antibiotics currently form the basic mode of treatment. Despite recent setbacks, pharmaceutical adjuncts form an interesting area of research.

    Under the auspices of the International Society for Neurovascular Disease (ISNVD), four expert panel committees were created from the ISNVD membership between 2011 and 2012 to determine and standardize noninvasive and invasive imaging protocols for detection of extracranial venous abnormalities indicative of chronic cerebrospinal venous insufficiency (CCSVI). The committees created working groups on color Doppler ultrasound (US), magnetic resonance (MR) imaging, catheter venography (CV), and intravascular US. Each group organized a workshop focused on its assigned imaging modality. Non-ISNVD members from other societies were invited to contribute to the various workshops. More than 60 neurology, radiology, vascular surgery, and interventional radiology experts participated in these workshops and contributed to the development of standardized noninvasive and invasive imaging protocols for the detection of extracranial venous abnormalities indicative of CCSVI. This ISNVD position statement presents the MR imaging and intravascular US protocols for the first time and describes refined color Doppler US and CV protocols. It also emphasizes the need for the use of for noninvasive and invasive multimodal imaging to diagnose adequately and monitor extracranial venous abnormalities indicative of CCSVI for open-label or double-blinded, randomized, controlled studies.

    The prevalence and the incidence of chronic and acute venous vascular disease has been shown to be globally very high, in both industrialized and developing countries. Chronic venous diseases of lower extremities are being an integral part of the third millennium's deadly angiopandemy, at the present time. The rate of the most severe cases with advanced stage of venous failure is approximately twice as high in the population (2.1 %) as has been assumed so far. Among venoactive drugs (VAD), micronized purified flavonoid fraction (MPFF) of diosmin hesperidin remains the agent with the highest degree of recommendation and it also indicated to pharmacotherapeutical support of leg ulcer healing, along with sulodexide and pentoxifylline. Compressive sclerotherapy, liquid or foam, is a safe and effective invasive method to treat telangiectasias, reticular varicose veins and subcutaneous varicose veins. Direct oral anticoagulants (DOAC) represent one of the therapeutic and preventive options of deep venous thrombosis (DVT) and of venous thromboembolism (VTE) with a limitation in patients with malignant conditions and in pregnancy. The most effective is triple simultaneous pharmaco-kinezio-mechano-phlebothromboemboloprophylaxis. Superficial vein thromboses longer than 5 cm are indicated to anticoagulant therapy too.

    Full Text Available Despite the high morbidity and mortality associated with venous thromboembolism in hospitalized medical patients with a number of risk factors, and large evidence that prophylaxis is effective, prophylaxis rates remain elusive in medically ill patients. Furthermore, in patients with renal failure, prophylaxis often is omitted or sub-optimal, due to fear of provoking hemorrhage. Patients with end-stage renal disease often have platelet deficits. Low molecular weight heparin (LMWH therapy may also be difficult to manage in these cases because LMWH clearance is largely dependent on the kidneys. Administration of LMWH to patients with some degree of renal failure may lead to bioaccumulation of anti-Xa activity with an increased risk of bleeding. In recent years, LMWH has largely replaced unfractionated heparin (UFH for the treatment and prophylaxis of thromboembolic disease. LMWHs have been shown to be superior to UFH in the prevention of venous thromboembolism. They are also easier to administer and do not require laboratory monitoring. However, several case reports and a metaanalysis indicate that the use of LMWHs at therapeutic doses in patients with advanced renal failure can be associated with major bleeding with serious adverse effects. In this paper, we review recent evidence supporting the safety of LMWHs at prophylactic doses in patients with mild or moderate renal disease. Current evidence suggests that bioaccumulation of enoxaparin (the most widely used LMWH can occur when the drug is used at standard therapeutic doses in patients with severely impaired renal function. This risk can be reduced by empiric dose reduction or monitoring of anti-Xa heparin levels.

    Lower limb deep vein thrombosis (DVT) is a common cause of significant morbidity and mortality. Systemic anticoagulation therapy is the mainstay of conventional treatment instituted by most physicians for the management of DVT. This has proven efficacy in the prevention of thrombus extension and reduction in the incidence of pulmonary embolism and rethrombosis. Unfortunately, especially in patients with severe and extensive iliofemoral DVT, standard treatment may not be entirely adequate. This is because a considerable proportion of these patients eventually develops postthrombotic syndrome. This is characterized by chronic extremity pain and trophic skin changes, edema, ulceration, and venous claudication. Recent interest in endovascular technologies has led to the development of an assortment of minimally invasive, catheter-based strategies to deal with venous thrombus. These comprise catheter-directed thrombolysis, percutaneous mechanical thrombectomy devices, adjuvant venous angioplasty and stenting, and inferior vena cava filters. This article reviews these technologies and discusses their current role as percutaneous treatment strategies for venous thrombotic conditions.

    Full Text Available Abstract Background and methods We report two clinical studies, one already published, performed in patients with early and advanced chronic venous insufficiency (CVI. In both, compression therapy and oral therapy with horse-chestnut seeds extracts (HCSE were compared to placebo. Results The published study in early CVI (Grade I showed HCSE and compression to be superior to placebo and to be equivalent to each other in reducing lower leg volume, a measure for oedema. In the study, in advanced CVI (Grade II and IIIa, compression appeared to be superior to placebo, whereas HCSE was not. HCSE fared better in Grade II than in Grade IIIa patients. These results are discussed in the light of data from an in vitro model, where HCSE has been able to close the intercellular gaps in the venular endothelium. Not fully specified factors lead to an opening of these gaps, resulting in oedema as well as in local coagulation and thrombosis. The subsequent inflammation keeps these gaps open and initiates and maintains a chronic disease process, which may be the starting point of CVI. Conclusion Due to its ability to close the venular endothelial gaps, HCSE seems to be a suitable and protecting therapy during the early stages of CVI. In later more severe stages compression therapy is indicated. Taking into account the observed negative impact of compression on quality of life, pharmacological CVI therapy should start early to avoid progress and to spare patients compression therapy.

    Full Text Available Abstract Introduction Gout is a common inflammatory arthritis caused by articular precipitation of monosodium urate crystals. It usually affects the first metatarsophalangeal joint of the foot and less commonly other joints, such as wrists, elbows, knees and ankles. Case presentation We report the case of a 75-year-old Caucasian man with tophaceous multiarticular gout, soft-tissue involvement and ulcerated tophi on the first metatarsophalangeal joint of the left foot, on the first interphalangeal joint of the right foot and on the left thumb. Conclusion Ulcers due to tophaceous gout are currently uncommon considering the positive effect of pharmaceutical treatment in controlling hyperuricemia. Surgical treatment is seldom required for gout and is usually reserved for cases of recurrent attacks with deformities, severe pain, infection and joint destruction.

    Sumi Surendran

    Full Text Available Chronic venous disease (CVD is one of the most prevalent yet underrated disorders worldwide. High heritability estimates of CVD indicate prominent genetic components in its etiology and pathology. Mutations in human forkhead box C2 (FoxC2 gene are strongly associated with valve failure in saphenous and deep veins of lower extremities. We explored the association of genetic variants of FoxC2 as well as FoxC2 mRNA and protein expression levels with CVD of lower limbs. We systematically sequenced the single coding exon, 5' and 3' flanking regions of FoxC2 gene in 754 study subjects which includes 382 patients with CVD and 372 healthy subjects. Four novel and three reported polymorphisms were identified in our cohort. Three variants in 5' flanking region and one in 3' flanking region of FoxC2 gene were significantly associated with CVD risk. FoxC2 mRNA in vein tissues from 22 patients was 4±1.42 fold increased compared to saphenous veins from 20 normal subjects (pT (rs34221221: C>T variant which is located in the FoxC2 putative promoter region was further analyzed. Functional analysis of c.-512C>T revealed increased mRNA and protein expression in patients with homozygous TT genotype compared to heterozygous CT and wild CC genotypes. Luciferase assay indicated higher transcriptional activity of mutant compared to wild genotype of this variant. These findings suggested that c.-512C>T variant of FoxC2 was strongly associated with susceptibility to CVD and also that this variant resulted in FoxC2 overexpression. To obtain a mechanistic insight into the role of upregulated FoxC2 in varicosities, we overexpressed FoxC2 in venous endothelial cells and observed elevated expression of arterial markers Dll4 and Hey2 and downregulation of venous marker COUP-TFII. Our study indicates altered FoxC2-Notch signaling in saphenous vein wall remodeling in patients with varicose veins.

    Full Text Available Abstract Background The association between proinflammatory cytokine gene polymorphisms and gastric diseases related to Helicobacter pylori varies by population and geographic area. Our objective was to determine if the IL-1B -511 T>C and -31 C>T polymorphisms and H. pylori vacA genotypes are associated with risk of chronic gastritis and gastric ulcer in a Mexican population. Methods We conducted endoscopic studies in 128 patients with symptoms of dyspepsia. We took two biopsies from the body, antrum, or ulcer edge from each patient, and classified our histopathological findings according to the Sydney System. H. pylori infection and vacA genotyping were accomplished via PCR from total DNA of the gastric biopsies. We confirmed the presence of anti-H. pylori serum IgG and IgM in 102 control subjects. In both case subjects and control subjects, the IL-1B -511 T>C polymorphism was genotyped by PCR-RFLPs and the IL-1B -31 C>T polymorphism was genotyped by pyrosequencing. Results Sixty-two point seven (62.7% of the 102 control subjects were H. pylori-seropositive. Among the case subjects, 100 were diagnosed with chronic gastritis and 28 with gastric ulcer. We found that 77% of the patients with chronic gastritis and 85.7% of the patients with gastric ulcer were H. pylori-positive. The predominant H. pylori genotype was vacA s1m1 (58.4% and the most frequent subtype was vacA s1. The -511 TC, (rs16944 -511 T>C genotype and the -511C allele were associated with chronic gastritis (OR = 3.1, 95% CI = 1.4-6.8 and OR = 3.0, 95% CI = 1.4-6.0, respectively. The subjects carrying -31T (rs1143627 -31 C>T were found to be at a higher risk of having chronic gastritis (OR = 2.8, 95% CI = 1.3-5.8. The IL-1B -511C/-31T haplotype was associated with chronic gastritis (OR = 2.1, 95% CI = 1.2-3.8 but not with gastric ulcer. Conclusions The H. pylori vacA genotypes identified herein were similar to those reported for other regions of Mexico. The vacA s1m1 genotype was

    Green tea is an infusion of unfermented leaves of Camellia sinensis (L.) Kuntze (Theaceae), traditionally used for the treatment of obesity, hypercholesterolemia, and gastric complaints. This study evaluated the mechanisms involved in the gastric ulcer healing of the hydroalcoholic extract from green tea (GEt), its ethyl acetate fraction, (GEAc) and epigallocatechin gallate (EGCG) using the model of acetic acid-induced gastric ulcer in rats. The chronic gastric ulcer was induced by application of 80 % acetic acid on serosal mucosa of rats. After 7 days of oral treatment with GEt and GEAc, the ulcer area, mucin content, inflammatory parameters (MPO and NAG), and antioxidant system (GSH and LOOH levels, SOD and GST activities) were evaluated. In vitro, the scavenging activity of GEt and GEAc were also measured. The antisecretory action was studied on the pylorus ligature method in rats. Oral treatment with GEt and GEAc reduced significantly the gastric ulcer area induced by acetic acid. The gastric ulcer healing was accompanied by increasing of mucin content, restoration of GSH levels and SOD activity, and reduction of MPO and LOOH levels. In addition, GEt and GEAc reduced the DPPH free radicals in vitro. Furthermore, the oral treatment of animals with GEt and GEAc did not alter the gastric acid secretion or cause signs of toxicity. Collectively, these results showed that GEt had a pronounced antiulcer effect, possibly through maintenance of mucin content and reduction of inflammation and oxidative stress. In addition, the compounds present in its ethyl acetate fraction could be responsible for the extract activity.

    Forty-six patients suffering from chronic duodenal ulcer, proven endoscopically, were treated in a randomized double-blind cross-over trial with either tri-potassium di-citrato bismuthate (De-Nol) or placebo for four weeks and assessed symptomatically and endoscopically. Those patients who failed to heal after treatment with either agent were crossed over to the alternative preparation and reassessed after a further 28 days. Forty-two patients completed the study involving 57 patient treatments. A highly significant improvement in both symptomatic response (P less than 0.01) and endoscopic healing (P less than 0.01) was seen in those patients receiving tri-potassium di-citrato bismuthate (De-Nol) as against placebo therapy.

    Full Text Available Thrombophilia is a rare but potentially catastrophic phenomenon occurring in patients having tendency of thrombosis. It may lead to serious complications. The etiology of thrombophilia is thought to be multifactorial and related to both acquired and inherited factors. Inflammatory bowel disease is an acquired cause of thrombophilia. Thromboembolic events are seen during inflammatory bowel disease, especially during the active period of the disease. In inflammatory bowel disease, thrombus formation in portal, splenic and mesenteric veins are not common. Besides, the association of genetic disorders related to metabolism of homocysteine with inflammatory bowel disease has been evidenced, especially in Crohn disease and rarely in ulcerative colitis. We present a rare case of ulcerative colitis in association with combined portal, splenic and mesenteric vein thrombosis. The patient was recently diagnosed with the disease which was in the inactive period. Interestingly, our patient was also heterozygous for the mutation in methylenetetrahydrofolate reductase (MTHFR gene.

    AIM: To determine the biological activity of Helicobacter pylori (Hpylori) lipopolysaccharide (H-LPS) and understand pathological correlation between H-LPS and human chronic gastritis and peptic ulcer.METHODS: H-LPS of a clinical Hpylori strain and LPS of Escherichia coli strain O55:B5 (E-LPS) were extracted by phenol-water method. Biological activities of H-LPS and E-LPS were detected by limulus lysate assay, pyrogen assay,blood pressure test and PBMC induction test in rabbits,cytotoxicity test in NIH 3T3 fibroblast cells and lethality test in NIH mice. By using self-prepared rabbit anti-H-LPS serum as the first antibody and commercial HRP-labeled sheep anti-rabbit sera as the second antibody, H-LPS in biopsy specimens from 126 patients with chronic gastritis (68 cases) or gastric ulcer (58 cases) were examined by immunohistochemistry.RESULTS: Fibroblast cytotoxicity and mouse lethality of H-LPS were weaker than those of E-LPS. But the ability of coagulating limulus lysate of the two LPSs was similar (+/0.5 ng/mL). At 0.5 h after H-LPS injection, the blood pressures of the 3 rabbits rapidly declined. At 1.0 h after H-LPS injection, the blood pressures in 2 of the 3 rabbits fell to zero causing death of the 2 animals. For the other one rabbit in the same group, its blood pressure gradually elevated. At 0.5 h after E-LPS injection, the blood pressures of the three rabbits also quickly declined and then maintained at low level for approximately 1.0 h. At 0.5 h after injection with H-LPS or E-LPS, PBMC numbers of the rabbits showed a remarkable increase. The total positivity rate of H-LPS from 126 biopsy specimens was 60.3%(76/126). H-LPS positivity rate in the biopsy specimens from chronic gastritis (50/68, 73.5%) was significantly higher than that from gastric ulcer (26/58, 44.8%) (X2=10.77,P<0.01). H-LPS positivity rates in biopsy specimens from chronic superficial gastritis (38/48, 79.2%) and chronic active gastritis (9/10, 90.0%) were significantly higher than

    Full Text Available The ulcerative haemosiderinic dyschromia of chronic venous insufficiency is difficult to heal and presents a high accumulation of iron. Lactoferrin, a potent natural iron chelator, could help to scar this ulcerative haemosi - derinic dyschromia. The objective of this study was to determine whether the topical application of a liposomal gel with Lactoferrin favors scarring/degradation of the brown colored spot typical of ulcerative haemosiderinic dyschromia. Nine patients with severe chronic venous insufficiency and ulcerative haemosiderinic dyschromia (CEAP-C6, with a natural evolution of over 12 months, were included in the study. Hemo chromatosis gene mutations were investigated. The levels of serum ferritin, transferrin saturation and blood cell counts were analyzed. The presence of hemosiderin was investigated through periulcerous and ulcer fundus biopsies carried out at baseline and 30 days after treatment with Lactoferrin. The severity of the injuries (CEAP classification was evaluated at the beginning of and throughout the whole 3-month treatment period. No patient had received compression treatment during the three months previous to this therapy. Significant improvement in these injuries, with a reduction in the dimensions of the brown spot (9 of 9 at Day 90, and complete scarring with a closure time ranging from 15 to 180 days (7 of 9 were observed. The use of topical lactoferrin is a non-invasive therapeutic tool that favors clearance of hemosiderinic dyschromia and scarring of the ulcer. The success of this study was not influenced either by the hemochromatosis genetics or the iron metabolism profile observed.

    Full Text Available Hypoxia causes remodeling and contractile responses in both pulmonary artery (PA and pulmonary vein (PV. Here we explore the effect of hypoxia on PV and pulmonary venous smooth muscle cells (PVSMCs.Chronic hypoxic pulmonary hypertension (CHPH model was established by exposing rats to 10% O2 for 21 days. Rat distal PVSMCs were isolated and cultured for in vitro experiments. The fura-2 based fluorescence calcium imaging was used to measure the basal intracellular Ca2+ concentration ([Ca2+]i and store-operated Ca2+ entry (SOCE. Quantitative RT-PCR and western blotting were performed to measure the expression of mRNA and levels of canonical transient receptor potential (TRPC protein respectively.Hypoxia increased the basal [Ca2+]i and SOCE in both freshly dissociated and serum cultured distal PVSMCs. Moreover, hypoxia increased TRPC6 expression at mRNA and protein levels in both cultured PVSMCs exposed to prolonged hypoxia (4% O2, 60 h and distal PV isolated from CHPH rats. Hypoxia also enhanced proliferation and migration of rat distal PVSMCs.Hypoxia induces elevation of SOCE in distal PVSMCs, leading to enhancement of basal [Ca2+]i in PVSMCs. This enhancement is potentially correlated with the increased expression of TRPC6. Hypoxia triggered intracellular calcium contributes to promoted proliferation and migration of PVSMCs.

    2013-01-01

    Full Text Available We aimed to assess the efficacy of Centella asiatica for improvement of the signs and symptoms of chronic venous insufficiency (CVI. We searched 13 electronic databases including the Cochrane Central Register of Controlled Trials for randomised controlled trials assessing the efficacy of Centella asiatica for CVI. Two review authors independently selected studies, assessed the risks of bias of included studies and extracted data. The treatment effects of similar studies were pooled whenever appropriate. Eight studies met the inclusion criteria. The pooling of data of similar studies showed that Centella asiatica significantly improved microcirculatory parameters such as transcutaneous partial pressure of CO2 and O2, rate of ankle swelling and venoarteriolar response. Three out of the eight studies did not provide quantitative data. However, these studies reported that patients treated with Centella asiatica showed significant improvement in CVI signs such as leg heaviness, pain and oedema. Our results show that Centella asiatica may be beneficial for improving signs and symptoms of CVI but this conclusion needs to be interpreted with caution as most of the studies were characterised by inadequate reporting and thus had unclear risks of bias, which may threaten the validity of the conclusions.

    Hemodialysis has been described as an important risk factor for the development of candidemia in patients suffering from chronic renal failure. The aim of this study was to evaluate the epidemiology of candidemia in outpatients with renal replacement therapy (RRT) by hemodialysis where the fungemia clearly represents a healthcare-associated infection. We retrospectively collected clinical and laboratory data from patients undergoing at least 3 months of RRT by hemodialysis who developed candidemia within 48h of hospital admission. We identified 14 patients with candidemia with central venous catheters (CVC) in place for 11-277 days before developing fungemia. Deep-seated infection was documented in 6 out of 14 candidiasis cases (43%), including 5 cases of endocarditis (36%).

    Background In the chronic stage of cerebral venous sinus thrombosis (CVST), recanalization can result in disparate MR appearances. We aimed to prospectively investigate the diagnostic accuracy of magnetic resonance venography (MRV) in the evaluation of the recanalization of CVST.Methods This study prospectively evaluated the diagnostic performance of 2-dimensional time-of-flight (2D-TOF) MRV in thirty-two consecutive patients during a three- to six-month follow-up for CVST. Both 2D-TOF MRV and digital substraction angiography (DSA) were undertaken. Diagnostic accuracy of 2D-TOF MRV in the detection of recanalized thrombus was evaluated using DSA as the reference standard.Results MRV and DSA were completed without complications in all 32 patients. The sensitivity, specificity, positive predictive value, and negative predictive value of 2D-TOF MRV for the detection of recanalization on a segmental basis were 91% (62/68), 93% (37/40), 95% (62/65), and 86% (37/43) respectively.Conclusion 2D-TOF MRV provides high sensitivity and specificity for the diagnosis of recanalized CVST segments.

    Chronic infusion of prostacyclin (PGI2) via a Broviac central venous line (CVL) is attended by risk of CVL-related complications, but we know of only one report regarding CVL-associated bloodstream infection (BSI) with PGI2 in children and none regarding other complications. We conducted a retrospective cohort study involving pediatric patients with pulmonary hypertension treated with chronic intravenous infusion of PGI2 at Boston Children's Hospital and determined the rate (per 1,000 line-days) of various CVL-related complications. We also determined how often complications necessitated line replacement and hospitalization, time to replacement of CVLs, and interpatient variability in the incidence of complications. From 1999 until 2014, 26 patients meeting follow-up criteria had PGI2 infusion, representing 43,855 line-days; mean follow-up was 56 months (range, 1.4-161 months). The CVL complication rates (per 1,000 line-days) were as follows: CVL-BSI, 0.25; superficial line infection, 0.48; impaired integrity, 0.59; occlusion, 0.09; and malposition, 0.32. The total complication rate was 1.73 cases per 1,000 line-days. All CVL-BSI and malposition cases were treated with CVL removal and replacement. Of CVLs with impaired integrity, 23 could be repaired and 3 required replacement. Six of 21 superficial CVL infections required replacement of the CVL. Three of 4 occluded CVLs were replaced. CVL complications occasioned 65 hospitalizations. There was marked interpatient variability in the rate of complications, much but not all of which appeared to be related to duration of CVL placement. We conclude that non-BSI complications are very significant and that efforts to teach and emphasize other aspects of line care are therefore very important.

    In patients with ulcerative colitis (UC), alterations of the intestinal microbiota, termed dysbiosis, have been postulated to contribute to intestinal inflammation. Fecal microbiota transplantation (FMT) has been used as effective therapy for recurrent Clostridium difficile colitis also caused by dysbiosis. The aims of the present study were to investigate if patients with UC benefit from FMT and if dysbiosis can be reversed. Six patients with chronic active UC nonresponsive to standard medical therapy were treated with FMT by colonoscopic administration. Changes in the colonic microbiota were assessed by 16S rDNA-based microbial community profiling using high-throughput pyrosequencing from mucosal and stool samples. All patients experienced short-term clinical improvement within the first 2 weeks after FMT. However, none of the patients achieved clinical remission. Microbiota profiling showed differences in the modification of the intestinal microbiota between individual patients after FMT. In 3 patients, the colonic microbiota changed toward the donor microbiota; however, this did not correlate with clinical response. On phylum level, there was a significant reduction of Proteobacteria and an increase in Bacteroidetes after FMT. FMT by a single colonoscopic donor stool application is not effective in inducing remission in chronic active therapy-refractory UC. Changes in the composition of the intestinal microbiota were significant and resulted in a partial improvement of UC-associated dysbiosis. The results suggest that dysbiosis in UC is at least in part a secondary phenomenon induced by inflammation and diarrhea rather than being causative for inflammation in this disease.

    Chronic impaired venous outflow from the central nervous system has recently been claimed to be associated with multiple sclerosis (MS) pathology. This resulted in the term chronic cerebrospinal venous insufficiency (CCSVI) in MS. The concept of CCSVI is based on sonography studies showing that impaired venous outflow leading to pathological reflux is almost exclusively present in MS patients but not in healthy controls. Based on these findings, a new pathophysiological concept has been introduced suggesting that chronic venous outflow obstruction and venous reflux in the CNS result in pathological iron depositions leading to inflammation and neurodegeneration. The theory of CCSVI in MS has rapidly generated tremendous interest in the media and among patients and the scientific community. In particular, the potential shift in treatment concepts possibly leading to an interventional treatment approach including balloon angioplasty and venous stent placement is currently being debated. However, results from recent studies involving several imaging modalities have raised substantial concerns regarding the CCSVI concept in MS. In this review article, we explain the concept of CCSVI in MS and discuss this hypothesis in the context of MS pathophysiology and imaging studies which have tried to reproduce or refute this theory. In addition, we draw some major conclusions focusing in particular on the crucial question as to whether interventional treatment options are expedient. In conclusion, the present conclusive data confuting the theory of CCSVI in MS should lead to reluctance with respect to the interventional treatment of possible venous anomalies in MS patients.

    Full Text Available Repetitive administration of medication or contrast agents is frequently performed in mice. The introduction of vascular access mini-ports (VAMP for mice allows long-term vascular catheterization, hereby eliminating the need for repeated vessel puncture. With catheter occlusion being the most commonly reported complication of chronic jugular vein catheterization, we tested whether digital subtraction angiography (DSA can be utilized to evaluate VAMP patency in mice.Twenty-three mice underwent catheterization of the jugular vein and subcutaneous implantation of a VAMP. The VAMP was flushed every second day with 50 μL of heparinized saline solution (25 IU/ml. DSA was performed during injection of 100 μL of an iodine based contrast agent using an industrial X-ray inspection system intraoperatively, as well as 7±2 and 14±2 days post implantation.DSA allowed localization of catheter tip position, to rule out dislocation, kinking or occlusion of a microcatheter, and to evaluate parent vessel patency. In addition, we observed different ante- and retrograde collateral flow patterns in case of jugular vein occlusion. More exactly, 30% of animals showed parent vessel occlusion after 7±2 days in our setting. At this time point, nevertheless, all VAMPs verified intravascular contrast administration. After 14±2 days, intravascular contrast injection was verified in 70% of the implanted VAMPs, whereas at this point of time 5 animals had died or were sacrificed and in 2 mice parent vessel occlusion hampered intravascular contrast injection. Notably, no occlusion of the catheter itself was observed.From our observations we conclude DSA to be a fast and valuable minimally invasive tool for investigation of catheter and parent vessel patency and for anatomical studies of collateral blood flow in animals as small as mice.

    Full Text Available Large vein endothelium plays important roles in clinical diseases such as chronic venous disease (CVD and thrombosis; thus to characterize CVD vein endothelial cells (VEC has a strategic role in identifying specific therapeutic targets. On these bases we evaluated the effect of the natural anti-inflammatory compounds α-Lipoic acid and Ginkgoselect phytosome on cytokines/chemokines released by CVD patient-derived VEC. For this purpose, we characterized the levels of a panel of cytokines/chemokines (n=31 in CVD patients’ plasma compared to healthy controls and their release by VEC purified from the same patients, in unstimulated and TNF-α stimulated conditions. Among the cytokines/chemokines released by VEC, which recapitulated the systemic profile (IL-8, TNF-α, GM-CSF, INF-α2, G-CSF, MIP-1β, VEGF, EGF, Eotaxin, MCP-1, CXCL10, PDGF, and RANTES, we identified those targeted by ex vivo treatment with α-Lipoic acid and/or Ginkgoselect phytosome (GM-CSF, G-CSF, CXCL10, PDGF, and RANTES. Finally, by investigating the intracellular pathways involved in promoting the VEC release of cytokines/chemokines, which are targeted by natural anti-inflammatory compounds, we documented that α-Lipoic acid significantly counteracted TNF-α-induced NF-κB and p38/MAPK activation while the effects of Ginkgo biloba appeared to be predominantly mediated by Akt. Our data provide new insights into the molecular mechanisms of CVD pathogenesis, highlighting new potential therapeutic targets.

    Arterial blood gas (ABG) analysis has an important role in the clinical assessment of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, arterial puncture or insertion of an arterial catheter has many drawbacks. The aim of this study was to evaluate whether venous blood gas (VBG) values of pH, partial pressure of carbon dioxide (PCO(2)) and oxygen (PO(2)), bicarbonate (HCO(3)), and oxygen saturation (SO(2)) can reliably predict ABG levels in patients with AECOPD. One hundred and thirty-two patients with a prior diagnosis of COPD presenting with acute exacerbation according to AECOPD criteria were included in this prospective study. AECOPD is defined as a recent increase in cough, wheezing, the volume and purulence of sputum or shortness of breath necessitating a change in regular medication, including corticosteroids or antibiotics. ABG samples were taken immediately after venous sampling, and both were analyzed. Linear regression analysis was performed and equations were established for the estimation of arterial values. The Pearson correlation coefficients for pH, PCO(2), HCO(3), PO(2), and SO(2) were 0.934, 0.908, 0.927, 0.252, and 0.296, respectively. There was a significant correlation between ABG and VBG values of pH, PCO(2), and HCO(3) (p arterial pH = 1.004 x venous pH; arterial PCO(2) = 0.873 x venous PCO(2); and arterial HCO(3) = 0.951 x venous HCO(3). VBG analysis can reliably predict the ABG values of pH, PCO(2) and HCO(3) in patients with AECOPD.

    Following the initial reports of Chronic Cerebrospinal Venous Insufficiency (CCSVI) and the purported curative potential of venoplasty, (coined the 'liberation' procedure) Canadians living with multiple sclerosis (MS) began to travel abroad to receive the unregulated procedure, often placing them at odds with their health providers. The purpose of this study was to determine the factors influencing older MS patients' decision to undergo the procedure in order to develop more specific and targeted health information. We performed secondary analysis of data collected as part of the 'Canadian Survey of Health Lifestyle and Aging with MS' from people over the age of 55 years with MS symptoms for 20 or more years. The survey consisted of self-reported information on impairments, disability, participation, demographics, personal and environmental factors. In order to compare respondents who underwent the procedure to those who did not and to develop a predictive model, we created a comparison group using a case-control algorithm, controlling for age, gender and education, and matching procedure cases to controls 1:3. We used multivariate stepwise least likelihood regression of 'a priori' variables to determine predictive factors. The prevalence of the 'liberation' procedure in our sample was 12.8% (95/743), substantially lower than reported in previous studies of complementary/alternative treatments in MS. The predictive model contained five factors; living alone (Odds ratio 0.24, 95%CI 0.09-0.63), diagnosis of anxiety (Odds ratio 0.29, 95%CI 0.10 - 0.84), rating of neurologist's helpfulness (Odds ratio 0.56, 95%CI 0.44 -0 .71), Body Mass Index (Odds ratio 0.93, 95%CI, 0.89 - 0.98) and perceived physical impact of MS (Odds ratio 1.02, 95%CI 1.01 - 1.04). Predictive factors differed from previous studies of complementary/alternative treatment use likely due to both the invasiveness of the procedure and the advanced age of our study cohort. Our findings suggest that

    Abductor hallucis (AH) is an intrinsic muscle of sole of the foot. It is commonly used in the coverage of ankle and heel defects and chronic nonhealing ulcers of the foot; its use is reported to have a favorable long-term outcome. The muscle's apt bulk and size, its simple surgical isolation, absence of donor-site defect, unvaried anatomy, and long neurovascular pedicle are some of the advantages that make it a promising muscle flap. During routine cadaver dissection in the Department of Anatomy of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, India, we identified an anatomical variation in AH in both feet of a 45-year-old embalmed male Indian cadaver. The variant muscle had innumerable proximal attachments, a majority of them arising atypically in the form of tough tendinous slips from the medial intermuscular septum at the junction of central and tibial components of plantar aponeurosis, the medial surface of first metatarsal and the intermuscular septum separating AH from the flexor hallucis brevis. The tendon: muscle ratio was 1.76, higher than the normal reported ratio of 0.56±0.07. This article highlights the variation noted and its implication for clinicians. On Internet search, we did not come across the variations described in our article. Findings of the anatomical variation reported in this article could benefit surgeons who decide to use AH flaps in the future. PMID:26634184

    Corticosteroids and 5-aminosalicylic acid are the primary standard therapy for inflammatory bowel disease. Recent immunologic data implicate an involvement of mast cell activation followed by increased histamine secretion and elevated tissue concentrations of histamine in the pathogenesis of ulcerative colitis. In the present case, the clinical course of a 35-year-old man with steroid-dependent chronic active ulcerative colitis, who did not respond to high-dose steroids, antibiotics, or azathioprine during 3 years, is reported. Clinical disease activity and established serological markers were recorded during 6 weeks of unsuccessful therapy and during the next 6 weeks, as a new nonsedative antihistaminergic drug, a mast cell stabilizer, and an hypoallergenic diet were implemented in addition to conventional therapy. Induction of remission was achieved within 2 weeks after treatment with fexofenadine, disodium cromoglycate, and an amino acid-based formula. Clinical disease activity, stool frequency, leukocytes, c-reactive protein, and orosomucoid levels in serum decreased rapidly. Daily steroid administration could be gradually reduced along with 6 weeks of this treatment. This report suggests that histamine and mast cell activity may be important pathophysiological factors responsible for persistent clinical and mucosal inflammatory activity in ulcerative colitis despite the use of steroids. In ulcerative colitis, patients unresponsive to conventional treatment, therapeutic considerations should also include an antiallergic approach when further signs of atopy or intestinal hypersensitivity are present.

    Intestinal inflammation induced with dextran sodium sulfate (DSS) is used to study acute or chronic ulcerative colitis in animal models. Decreased gut tissue anti-inflammatory cytokine IL-10 concentration and mRNA abundance are associated with the development of chronic bowel inflammation. Twelve piglets of 3 days old were fitted with an intragastric catheter and randomly allocated into control and DSS groups by administrating either sterile saline or 1.25 g of DSS/kg body weight (BW) in saline per day, respectively, for 10 days. Growth rate and food conversion efficiency were reduced (p<0.05) in the DSS piglets compared with the control group. Quantitative histopathological grading of inflammation in the jejunum and colon collectively showed that the DSS treatment resulted in 12 fold greater (p<0.05) inflammation severity scoring in the colon than in the jejunum, indicative of chronic ulcerative colitis in the colon. Upper gut permeability endpoint was 27.4 fold higher (p<0.05) in the DSS group compared with the control group. The DSS group had higher concentrations and mRNA abundances (p<0.05) of TNF-alpha and IL-6 in the jejunal and colonic tissues compared with the control group. Colonic concentration and mRNA abundance of IL-10 were reduced (p<0.05), however, jejunal IL-10 mRNA abundance was increased (p<0.05) in the DSS group compared with the control group. In conclusion, administration of DSS at 1.25 g/kg BW for 10 days respectively induced acute inflammation in the jejunum and chronic inflammation and ulcerative colitis in the colon with substantially decreased colonic concentration and mRNA abundance of IL-10 in the young pigs, mimicking the IL-10 expression pattern in humans Associated with chronic bowel inflammation.

    Zinc has been reported to exert a gastroprotective action against various experimental gastric lesions suggesting that this trace element is involved in the integrity of the gastric mucosa. Compounds containing zinc, such as polaprezinc, were developed in Japan and used as an antiulcer drugs in the treatment of human peptic ulcer disease. However, the precise mechanism of Zn(2+) containing compounds and their effects on mucosal integrity, gastroprotection and ulcer healing remain unclear. We have determined the efficacy of zinc hydroaspartate, a compound containing Zn(2+), in the mechanism of gastric secretion and ulcer healing in rats with chronic gastric ulcers induced by acetic acid (initial ulcer area = 28 mm(2)). Rats with gastric ulcers were randomized into two groups: A) with gastric fistulas (GF) and B) without gastric fistulas and received a daily treatment with zinc hydroaspartate (32-130 mg/kg-d i.g.) for 3, 7 and 14 days. At the termination of each treatment, the area of gastric ulcers were examined by planimetry, the gastric blood flow (GBF) at ulcer margin was assessed by laser Doppler flowmetry and H(2)-gas clearance methods. The venous blood was withdrawn for a measurement of plasma gastrin levels by radioimmunoassay (RIA). The concentration of Zn(2+) in the gastric juice and mucosa at the ulcer margin were determined by differential pulse anodic stripping voltammetry (DPASV) and flame atomic absorption spectrometry (FAAS) methods and the gastric biopsy samples were taken for histopathological assessment of the quality of ulcer healing. The ulcers healed gradually, with the ulcer area in the vehicle control rats being diminished by 15%, 48% and 78% upon ulcer induction at 3, 7 and 14 days, respectively. Zinc hydroaspartate dose-dependently inhibited the area of gastric ulcer, the dose reducing this area by 50% (ID(50)) being about 60 mg/kg-d. The mucosal concentration of Zn(2+) significantly was unchanged from the baseline immediately after ulcer

    Full Text Available Abstract Background Several studies have reported hypoperfusion of the brain parenchyma in multiple sclerosis (MS patients. We hypothesized a possible relationship between abnormal perfusion in MS and hampered venous outflow at the extracranial level, a condition possibly associated with MS and known as chronic cerebrospinal venous insufficiency (CCSVI. Methods We investigated the relationship between CCSVI and cerebral perfusion in 16 CCSVI MS patients and 8 age- and sex-matched healthy controls. Subjects were scanned in a 3-T scanner using dynamic susceptibility, contrast-enhanced, perfusion-weighted imaging. Cerebral blood flow (CBF, cerebral blood volume (CBV and mean transit time (MTT were measured in the gray matter (GM, white matter (WM and the subcortical GM (SGM. The severity of CCSVI was assessed according to the venous hemodynamic insufficiency severity score (VHISS on the basis of the number of venous segments exhibiting flow abnormalities. Results There was a significant association between increased VHISS and decreased CBF in the majority of examined regions of the brain parenchyma in MS patients. The most robust correlations were observed for GM and WM (r = -0.70 to -0.71, P P corrected = 0.022, and for the putamen, thalamus, pulvinar nucleus of thalamus, globus pallidus and hippocampus (r = -0.59 to -0.71, P P corrected Conclusions This pilot study is the first to report a significant relationship between the severity of CCSVI and hypoperfusion in the brain parenchyma. These preliminary findings should be confirmed in a larger cohort of MS patients to ensure that they generalize to the MS population as a whole. Reduced perfusion could contribute to the known mechanisms of virtual hypoxia in degenerated axons.

    Background Chronic dermal ulcers are also referred to as refractory ulcers, This study was conducted to elucidate the therapeutic effect of laser on chronic dermal ulcers and the induced expression of heat shock factor 1 (HSF1) and heat shock protein 70 (HSP70) in wound tissues.Methods Sixty patients with 84 chronic dermal ulcers were randomly divided into traditional therapy and laser therapy groups. Laser treatment was performed in addition to traditional therapy in the laser therapy group. The treatment efficacy was evaluated after three weeks. Five tissue sections of healing wounds were randomly collected along with five normal skin sections as controls. HSP70-positive cells from HSP70 immunohistochemical staining were counted and the gray scale of positive cells was measured for statistical analysis. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were performed to determine the mRNA and protein expressions of HSF1 and HSP70.Results The cure rate of the wounds and the total efficacy in the laser therapy group were significantly higher than those in the traditional therapy group (P<0.05, P<0.01, respectively). Immunohistochemical staining revealed that the HSP70-positive cell count was significantly higher in laser therapy group than those in the traditional therapy group and controls (P<0.01), and the gray scale of the cell signal was obviously lower than traditional therapy group and controls (P <0.05). By contrast, the traditional therapy group and the control group were not significantly different. The RNA levels of HSF1 and HSP70 were higher in the laser therapy group by RT-PCR, but very low in normal skin and the traditional therapy group. The analysis on the gray scale of the Western blot bands indicated that the expression of HSF1 and HSP70 in the laser therapy group was significantly higher than in the traditional therapy group and the control group (P <0.01), and the expression in the traditional therapy group was also

    Solcoseryl, a deproteinized extract of calf blood, and EGF, produced by salivary glands, have been shown to enhance the healing of peptic ulcerations, but the mechanism of this effect is unknown. Since both solcoseryl and EGF have been reported to stimulate cell proliferation, we designed the study to compare the ulcer healing and growth promoting actions of these two agents in the same animals. Gastric and duodenal ulcerations were produced by serosal application of 100% acetic acid on an area of 13.8 mm2 of gastric and duodenal wall, respectively. In the control animals, 7 days after ulcer induction, the mean ulcer area was reduced to 7.1 +/- 1.2 mm2 in the stomach, and to 6.1 +/- 0.8 mm2 in the duodenum. After 14 days all ulcers were healed, both in the stomach and duodenum. Oral administration of solcoseryl (10 ml/kg-day) or EGF (30 micrograms/kg-day) for 7 days after ulcer induction resulted in a significant reduction in the ulcer area in the stomach, and to a greater extent in the duodenum. This enhancement of ulcer healing by solcoseryl was accompanied by a significant increase in the weight of the duodenal mucosa and the total contents of DNA and RNA after 7 days of treatment, and in the weight and nucleic acid contents in both the gastric and duodenal mucosa after 14 days of treatment. EGF also increased the weights and the nucleic acid contents in gastric and duodenal mucosa, but this was significant only after 14 days of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

    The objective of this study was to evaluate the level of healing of chronic neuropathic plantar ulcers, using an irremovable windowed fibreglass cast boot, which is only opened after healing. A single-centre prospective study of a cohort of 177 diabetic patients with chronic neuropathic plantar ulcers was carried out. The duration of neuropathic plantar ulcers was 604 ± 808 days, with a mean surface area of 4.6 ± 6.5 cm(2) , a mean depth of 1.04 ± 1.08 cm and a mean volume of 5.9 ± 17.7 cm(3) . After a mean of 96 days of wearing a windowed fibreglass cast boot (min 9 days, max 664 days and median 68 days), the level of healing reached 83.6%, although 29 patients did not heal (16.4%). The compliance was at 95%. NPUs with bigger volumes (p = 0.037) and those located at the heels ( p = 0.004) had significantly lower healing levels. Twenty-one patients had moderate peripheral arterial disease (12%), and 24 patients were ostectomized for underlying osteomyelitis (14%), before inclusion. Moderate peripheral arterial disease (p = 0.970) or operated osteomyelitis (p = 0.128) did not modify the level of healing significantly, which were of 81% and 70.8%, respectively. Complications include 12 ulcers due to the windowed fibreglass cast boot (i.e. 7%) and two other ulcers being moderately infected, resulting in 2% of toe amputation, but there was no major amputation or phlebitis. The treatment of old and deep NPUs of the diabetic foot by wearing a windowed fibreglass cast boot without opening the boot prior to healing offers very high ulcer recovery levels. Windowed fibreglass cast boots were changed in only 26 cases (14.6%). In addition, compliance was excellent and of the order of 95%. Furthermore, moderate peripheral arterial disease or a recent ostectomy did not affect the efficacy of windowed fibreglass cast boot.

  20. [Innovative therapy for leg ulcers: Electrostimulation].

    Maillard, H

    2015-01-01

    Chronic wounds can take a long time to heal despite appropriate therapy based upon aetiology and use of suitable dressings. The success of electrostimulation is based upon the existence within the skin of the endogenous currents involved in the wound healing process. Where skin continuity is broken by a wound, these electrical potentials are short-circuited, resulting in leakage of electrical current. Woundel(®) therapy is the only such treatment currently available in France and is based on the use of continuous pulsed current that generates an electrical field near the endogenous electrical fields. It utilises a console to deliver the electrical impulses, a dressing electrode and a dispersion electrode. The electrode dressing is left on the wound for 3 days, and venous compression bandaging may be applied to the leg, taking care to leave the connector free. Negative polarity stimulates migration of fibroblasts, resulting in elimination of fibrin. Positive polarity causes keratinocyte migration, which in turn leads to epidermisation. Electrostimulation is of recognised utility in the healing of chronic wounds: it has been assigned a high-level recommendation in the European and American guidelines for the treatment of venous ulcers and bedsores with proof level of A. Further, the analgesic effect of electrostimulation has been demonstrated in several studies. Electrostimulation is already well developed in France among wound specialists, but prospective studies are planned so that it may be used at patients' homes.

Using EchoColorDoppler (ECD to assess chronic CCSVI is a very difficult and long examination. It takes about an hour even for an expert sonographer. Methods: Hemodynamic morphological map (MEM-Net is a program that works on the Internet. All the morphological and hemodynamic data of the patient can be entered into the program’s anatomical scheme to create a map of the ECD report. The program also allows us to collect all the data during the ECD assessment and, using its algorithm, make the report uniform. Conclusion: Reporting on the map by using MEM-net shortens the time of ECD written reporting that is done automatically. The program also makes a blind control of the report and enables the use of it for scientific research. We hope that in the future everyone will use this data collection tool for all scientific work on this topic. Keywords: CCSVI, ECD, Map, cerebral venous system, sonography

    Introduction Peripherally inserted central venous catheters (PICCs) may adversely impact future successful arteriovenous fistulae (AVF). As part of a quality improvement project, the performance of tunneled small bore tunneled central venous catheters (TSB-CVCs), as alternatives to PICCs, was evaluated. Methods A retrospective observational study, involving individuals ≥18 years of age who underwent TSB-CVC placement by Interventional Radiology at Mayo Clinic, Rochester, MN between 1/1/2010 and 8/30/2013. Findings The study cohort included 92 patients with a median age of 55 (46-67) years, who underwent 108 TSB-CVC placements. Baseline renal disease was present in 71% (77/108). Most TSB-CVCs were placed in hospitalized patients (94%; 102/108); five French in diameter (61%; 66/108) and located in an internal jugular vein (84%; 91/108). Median catheter indwelling time was 20 (11-43) days (n = 84). TSB-CVC-related bloodstream infection, deep venous thrombosis (DVT), and superficial venous thrombosis (SpVT) rates per line were 0.009 (1/108), 0.018 (2/108), and 0.009 (1/108), respectively. Venous outcomes in a subgroup of 54 patients, who had documented PICC placements (n = 161) in addition to TSB-CVC (n = 58) were compared. TSB-CVC-DVT rate was lower than the PICC-DVT rate (0.017 [1/58] vs. 0.106 per line [17/161]; P = 0.04). The TSB-CVC-SpVT rate was not different from the PICC-SpVT rate (0 [0/58] vs. 0.037 [6/161] per line; P = 0.14). Discussion TSB-CVCs demonstrated an excellent safety profile in our study. These catheters should be preferentially utilized for arm vein preservation in advanced kidney disease. Their impact on future AVF success needs further evaluation.

    Ethanol is a psychoactive substance highly consumed around the world whose health problems include gastric lesions. Baccharis trimera is used in folk medicine for the treatment of gastrointestinal disorders. However, few studies have evaluated its biological and toxic effects. To validate the popular use of B. trimera and elucidate its possible antiulcerogenic and cytotoxic mechanisms, a hydroethanolic extract of B. trimera (HEBT) was evaluated in models of gastric lesions. Rats and mice were used to evaluate the protective and antiulcerogenic effects of HEBT on gastric lesions induced by ethanol, acetic acid, and chronic ethanol consumption. The effects of HEBT were also evaluated in a pylorus ligature model and on gastrointestinal motility. The LD50 of HEBT in mice was additionally estimated. HEBT was analyzed by nuclear magnetic resonance, and a high-performance liquid chromatography fingerprint analysis was performed. Oral HEBT administration significantly reduced the lesion area and the oxidative stress induced by acute and chronic ethanol consumption. However, HEBT did not protect against gastric wall mucus depletion and did not alter gastric secretory volume, pH, or total acidity in the pylorus ligature model. Histologically, HEBT accelerated the healing of chronic gastric ulcers in rats, reflected by contractions of the ulcer base. Flavonoids and caffeoylquinic acids were detected in HEBT, which likely contributed to the therapeutic efficacy of HEBT, preventing or reversing ethanol- and acetic acid-induced ulcers, respectively. HEBT antiulcerogenic activity may be partially attributable to the inhibition of free radical generation and subsequent prevention of lipid peroxidation. Our results indicate that HEBT has both gastroprotective and curative activity in animal models, with no toxicity.

    Hyaluronic acid (HA) and its derivatives are used for chronic wounds, but evidence of their effectiveness remains unclear. The aim of this study was to provide more updated evidence for the effectiveness of HA (or its derivatives) compared with placebo or other agents for promoting healing in chronic wounds. The Cochrane Central Register of Controlled Trials, MEDLINE via Ovid Online, CINAHL and the EMBASE via EBSCO host databases were searched. Drug companies and experts in wounds were also contacted. Randomised controlled trials of HA (or its derivatives) compared with control were eligible for inclusion. We identified nine randomised controlled trials involving 865 participants with chronic wounds were included in the review. The reporting for mixed arterial and venous ulcers seems to be better quality than that for venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). Studies provided little evidence regarding the claimed effects of HA or its derivaties on healing of chronic wounds. However, there is some evidence on their effectiveness for reducing pain intensity for mixed arterial and venous ulcers, which involved 255 patients (MD=-6.78 [95% CI: -11.10 to -2.46]). Evidence to guide decisions regarding the use of HA or its derivatives to promote wound healing is still limited. More good-quality randomised controlled trials are warranted.

    Ughi, Nicola; Crotti, Chiara; Ingegnoli, Francesca

    2016-01-01

    Digital ulcers (DUs) are a severe and frequent clinical feature of patients with systemic sclerosis (SSc). The presence of DUs may cause severe pain and often lead to impairment of patient's functional activities and health-related quality of life. Moreover, poor patient cooperation during the wound care procedure due to pain may be associated with a negative outcome of DU healing. Therefore, pain management has a key role in patients with SSc. These two case reports describe the effectiveness and safety of oxycodone/naloxone in patients with SSc complicated by painful chronic DUs. Such a therapy has provided pain relief and consequently an increased compliance during redressing wounds.

    Association between chronic venous disease and obesity has recently been studied, with indications that it may worsen in obese patients. The aim of study was to correlate clinical classes of chronic venous disease according to Clinical Etiology Anatomy Pathophysiology (CEAP) classification and body mass index, as well as to compare the severity of chronic venous disease in obese and nonobese patients. This retrospective cross-sectional prevalence study was conducted at the Maringá State University and Belczak Vascular Center along a period of 2 years, consisting of a random sample of 482 patients with complaints compatible with chronic venous disease. Data obtained from patient's files included gender, age, weight and height (for calculating body mass index), and clinical class (C) of chronic venous disease according to CEAP classification. Statistical analysis included Spearman's correlation coefficient, Chi-square test (for comparing frequencies), and Student's t-test (for comparing means). Significant positive correlation between body mass index and clinical classes was established for women (0.43), but not for men (0.07). Obesity (body mass index  : ≥  : 30.0) was significantly more frequent in patients with chronic venous disease in clinical classes 3 (p venous disease in clinical class 1 (p venous disease in women, but not in men. It also corroborated the negative impact of obesity on the clinical severity of chronic venous disease.

    2010-01-01

    Full Text Available The present study was designed to investigate whether Cissus quandrangularis extract (CQE had healing effects on gastric ulcer, through modulation of polyamines and proliferating cell nuclear antigen (PCNA in rats. Administration of acetic acid (AA was accompanied by reduced PCNA which was determined by immunohistochemical staining, 3 H-thymidine incorporation using liquid scintillation spectrometry, mitochondrial marker enzymes, polyamine contents and transforming growth factor-alpha (TGF-a expression in gastric mucosa of rats. Administration of CQE after the application of AA to the stomach enhanced the reduction of ulcer area in a dose-dependent manner which was confirmed by histoarchitecture. Moreover, CQE significantly increased the 3 H-thymidine incorporation and the levels of polyamines such as putrescine, spermine and spermidine in ulcerated rats. In addition, the extract offers gastroprotection in the ulcerated area by increased expression of TGF-a and also reversed the changes in the gastric mucosa of ulcerated rats with significant elevation in mitochondrial tricarboxylic acid (TCA cycle enzymes and PCNA levels. Based on these results, the healing effect of CQE on AA induced gastric mucosal injury in rats may be attributed to its growth promoting and cytoprotective actions, possibly involving an increase in tissue polyamine contents and cell proliferation.

    1988-01-01

    A new system to study capillary permeability, the VSC (vacuum suction chamber) device has been developed to evaluate the variations of capillary permeability in postphlebitic limbs. The VSC device produces by negative pressure [obtained in a plastic chamber applied to the skin at the perimalleolar region] a wheal which disappears in normals in less than one hour. In twelve patients with moderate [superficial] venous hypertension and in twelve patients with postphlebitic limbs the time of disappearance of the wheals was significantly longer in comparison with ten normal limbs. There was also a significantly increased time of disappearance of the wheals in postphlebitic legs in comparison with those with superficial incompetence. The validation of the VSC technique with venous occlusion plethysmography (VOP) showed that the increase of time of disappearance of the wheals is well correlated with the increase of capillary permeability demonstrated by VOP. After 2 weeks treatment with Venoruton (at the dosage of 1000 mg t.i.d.) the time of disappearance of the wheal was significantly reduced in both groups of patients (while it was unchanged in normals). Laser-Doppler parameters used together with the VSC device to evaluate the microcirculatory changes associated with an altered capillary permeability also showed a significant improvement of the laser-Doppler parameters after treatment. In conclusion there is evidence by the VSC device that capillary permeability [which is abnormally increased] in chronic venous hypertension is improved [decreased] after treatment for two weeks with Venoruton. This study demonstrated also the efficacy of the VSC device to study capillary permeability and the effects of drugs active on capillary permeability.

    Full Text Available Objective: Pressure ulcer is a chronic wound. It reduces the quality of life of the elderly and individuals with restricted range of motion. It prolongs hospital stay and increases the risk of complications. The cost is quite high. Preventive actions for the prevention of pressure ulcers should be developed. Planning protocols and standards of care are among the main targets. Material and Method: Research was conducted in one-year period between 2012 May and 2013 May on patients who were followed up in Akdeniz University Hospital clinics and intensive care unit with pressure ulcers. The research population consisted of 569 patients. Patient data were recorded in SPSS 16 for Windows program. Statistical analyzes were performed with retrospective methods. The demographic characteristics of patients with pressure ulcers were analyzed as frequency and descriptive statistics. Prevalence and incidence of one year were calculated. Results: Of the patients, 58% were males, 42% were females. Of the patients, 36% were in the age range of 61-80 years, and their average length of stay was 42,9 days. Of the patients, 70% were at stage 2 and 3. In 15% of patients pressure ulcers occurred on the first day of hospitalization. Pressure ulcers were developed between days 2 and 10 in 59% of the patients. Prevalence rate was 2.5%, the incidence was 1.9%, the prevalence rate was 5.9% in the intensive care unit. Conclusion: It is easier to prevent pressure ulcers than treating.

    We performed a monocentric observational prospective study to evaluate coagulation activation and endothelial dysfunction parameters in patients with multiple sclerosis undergoing endovascular treatment for cerebro-spinal-venous insufficiency. Between February 2011 and July 2012, 144 endovascular procedures in 110 patients with multiple sclerosis and chronical cerebro-spinal venous insufficiency were performed and they were prospectively analyzed. Each patient was included in the study according to previously published criteria, assessed by the investigators before enrollment. Endothelial dysfunction and coagulation activation parameters were determined before the procedure and during follow-up at 1, 3, 6, 9, 12, 15 and 18 months after treatment, respectively. After the endovascular procedure, patients were treated with standard therapies, with the addition of mesoglycan. Fifty-five percent of patients experienced a favorable outcome of multiple sclerosis within 1 month after treatment, 25% regressed in the following 3 months, 24.9% did not experience any benefit. In only 0.1% patients, acute recurrence was observed and it was treated with high-dose immunosuppressive therapy. No major complications were observed. Coagulation activation and endothelial dysfunction parameters were shown to be reduced at 1 month and stable up to 12-month follow-up, and they were furthermore associated with a good clinical outcome. Endovascular procedures performed by a qualified staff are well tolerated; they can be associated with other currently adopted treatments. Correlations between inflammation, coagulation activation and neurodegenerative disorders are here supported by the observed variations in plasma levels of markers of coagulation activation and endothelial dysfunction.

    Presented herein is the authors' experience in endovascular laser obliteration of the major trunks of the grate saphenous vein (GSV) with a wide ostial segment (measuring from 15 to 34 mm) in patients presenting with chronic venous insufficiency. Group One patients (n=32) underwent crossectomy followed by endovasal laser obliteration (EVLO) of the GSV's trunk on the femur. Group Two patients (n=46) were not subjected to crossectomy, whereas obliteration of the GSV's trunk was carried out immediately from the ostium. In Group One we managed to achieve obliteration of the GSV's trunk in 32 patients (100%) with no additional interventions, and in Group Two this was achieved in 42 (91.3%) patients. Four patients (8.7%) required performing a secondary procedure of EVLO after which obliteration of the trunk was achieved in all patients of Group Two. There was no evidence of deep-vein thrombosis.

    The aim of this study was to evaluate the prevalence, clinical characteristics and management of chronic venous disease (CVD) in patients seen at primary care clinics This cross-sectional study was carried-out in Spain by 999 primary care physicians. They recruited 20 consecutive patients who were attending their clinics for any reason except for a medical emergency. The following Information was collected: demographic data, CVD risk factors, physical examination, clinical characteristics of the CVD and how it was managed. 19,800 patients were included, predominantly women (63%), with a mean age of 53.7 ± 20 years. The prevalence of CVD (CEAP categories C1 to C6) was 48.5% (95% CI, 47.8 to 49.2), significantly higher in women (58.5%; 95% CI, 57.6 to 59.4) than in men (32.1%; 95% CI, 31.0 to 33.1). The greater the age the higher the prevalence and the more advanced the CVD. Ninety-nine percent of the patients required some form of treatment, with a greater proportion among women (72% vs. 39%, P<.0001). Sclerotherapy, endothermal ablation or surgery was required by 4% of the patients. Referral to the specialist was considered for 7% of the patients. Chronic venous disease is highly prevalent among patients seen at primary care clinics in Spain, especially in women and elderly patients. Referral to a specialist and/or the use of the more invasive treatment procedures is uncommon. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    Venous infarction in the cerebellum has been reported only rarely, probably because of the abundant venous collateral drainage in this region. Bilateral occipital infarction is a rare cause of visual loss in cerebral venous thrombosis. We describe a 50-year-old woman with a history of ulcerative colitis who developed acute cerebellar ataxia and cortical blindness. She had bilateral cerebellar and occipital lesions related to sigmoid venous thrombosis and achieved complete recovery with anticoagulation therapy. Cerebral venous thrombosis should be considered in cases of simultaneous cerebellar and occipital vascular lesions.

    BACKGROUND: Arterial blood gases (ABGs) are often sampled incorrectly, leading to a \\'mixed\\' or venous sample. Delays in analysis and air contamination are common. OBJECTIVES: We measured the effects of these errors in patients with chronic obstructive pulmonary disease (COPD) exacerbations and controls. METHODS: Arterial and venous samples were analyzed from 30 patients with COPD exacerbation and 30 controls. Venous samples were analysed immediately and arterial samples separated into non-air-contaminated and air-contaminated specimens and analysed at 0, 30, 60, 90 and 180 min. RESULTS: Mean venous pH was 7.371 and arterial pH was 7.407 (p < 0.0001). There was a correlation between venous and arterial pH (r = 0.5347, p < 0.0001). The regression equation to predict arterial pH was: arterial pH = 4.2289 + 0.43113 . venous pH. There were no clinically significant differences in arterial PO associated with analysis delay. A statistically significant decline in pH was detected at 30 min in patients with COPD exacerbation (p = 0.0042) and 90 min in controls (p < 0.0001). A clinically significant decline in pH emerged at 73 min in patients with COPD exacerbation and 87 min in controls. Air contamination was associated with a clinically significant increase in PO in all samples, including those that were immediately analyzed. CONCLUSIONS: Arterial and venous pH differ significantly. Venous pH cannot accurately replace arterial pH. Temporal delays in ABG analysis result in a significant decline in measured pH. ABGs should be analysed within 30 min. Air contamination leads to an immediate increase in measured PO, indicating that air-contaminated ABGs should be discarded.

    Full Text Available Background: Incidences of side effects and relapses are very common in chronic ulcerative colitis patients after termination of the treatment. Aims and Objectives: This study aims to compare the treatment with monoherbal formulation of Holarrhena antidysenterica with Mesalamine in chronic ulcerative colitis patients with special emphasis to side effects and relapse. Settings and Design: Patients were enrolled from an Ayurveda Hospital and a private Hospital, Gujarat. The study was randomized, parallel group and single blind design. Materials and Methods: The protocol was approved by Institutional Human Research Ethics Committee of Anand Pharmacy College on 23rd Jan 2013. Three groups (n = 10 were treated with drug Mesalamine (Group I, monoherbal tablet (Group II and combination of both (Group III respectively. Baseline characteristics, factors affecting quality of life, chronicity of disease, signs and symptoms, body weight and laboratory investigations were recorded. Side effects and complications developed, if any were recorded during and after the study. Statistical Analysis Used: Results were expressed as mean ± SEM. Data was statistically evaluated using t-test, Wilcoxon test, Mann Whitney U test, Kruskal Wallis test and ANOVA, wherever applicable, using GraphPad Prism 6. Results: All the groups responded positively to the treatments. All the patients were positive for occult blood in stool which reversed significantly after treatment along with rise in hemoglobin. Patients treated with herbal tablets alone showed maximal reduction in abdominal pain, diarrhea, and bowel frequency and stool consistency scores than Mesalamine treated patients. Treatment with herbal tablet alone and in combination with Mesalamine significantly reduced the stool infection. Patients treated with herbal drug alone and in combination did not report any side effects, relapse or complications while 50% patients treated with Mesalamine exhibited the relapse with
