Chronic venous leg ulcers are the most common wounds seen in general practice. Their management can be both challenging and time-consuming. To produce a short practical guideline incorporating the TIME concept and A2BC2D approach to help general practitioners and their practice nurses in delivering evidence-based initial care to patients with chronic venous leg ulcers. Most chronic venous leg ulcers can be managed effectively in the general practice setting by following the simple, evidence-based approach described in this article. Figure 1 provides a flow chart to aid in this process. Figure 2 illustrates the principles of management in general practice. Effective management of chronic ulcers involves the assessment of both the ulcer and the patient. The essential requirements of management are to debride the ulcer with appropriate precautions, choose dressings that maintain adequate moisture balance, apply graduated compression bandage after evaluation of the arterial circulation and address the patient's concerns, such as pain and offensive wound discharge.

Full Text Available The venous ulcer is a skin lesion that affects the lower third of the legs. Is associated with chronic venous insufficiency, is the leading cause of ulcers of the lower limbs. Can interfere with the quality of life of patients, because it generates negative repercussions on social and economic sphere. The aim of this study was to identify self-care in the home environment of patients with venous ulcers, to assess the occurrence of alternative therapy use and verifythe involvement of domestic trauma. Methodologically, this study takes a quantitative and qualitative analytical cross-sectional held at the Clinical School of Physiotherapy, State University of Southwest Bahia / UESB / Jequié-BA, from January 2007 to September 2008. Data were collected through a questionnaire and semi-structured interviews. The results showed that 100% of the participants played self care of their injuries, including with respect to occlusion and bandages when needed. However, 6.25% said they had not received adequate information to perform self-care. Concluded that it is necessary to interact and produce a mechanism between education and health assistance for the development of the practice of self-care in family life at home.

This study set out to define realistic protocols of care for the treatment of chronic venous leg ulcers and pressure ulcers in France and, by developing cost-effectiveness models, to compare the different protocols of care for the two ulcer groups, enabling a calculation of direct medical costs per ulcer healed in a typical French health insurance plan. Clinical outcomes and some treatment patterns were obtained from published literature. Validations of different treatment patterns were developed using an expert consensus panel similar to the Delphi approach. Costs were calculated based on national averages and estimates from the UK and Germany. The models were used to measure costs per healed ulcer over a 12-week period. For both the pressure ulcer and venous leg ulcer models, three protocols of care were identified. For pressure ulcers and venous leg ulcers, the hydrocolloid DuoDERM (ConvaTec, also known as Granuflex in the UK and Varihesive in Germany) was most cost-effective in France. The combination of published data and expert consensus opinion is a valid technique, and in this case suggests that treating pressure ulcers and venous leg ulcers with hydrocolloid dressings is more cost-effective than treating them with saline gauze, in spite of the lower unit cost of the latter.

The causes of skin damage and leg ulceration in chronic venous disease.

Science.gov (United States)

Smith, Philip Coleridge

Chronic venous disease with skin changes of the leg is a common condition affecting up to 1 in 20 people in westernized countries. The causes of this problem are not fully understood, although research in recent years has revealed a number of important mechanisms that contribute to the disease process. Patients with chronic venous disease suffer persistently raised pressures in their deep and superficial veins in the lower limb. Leucocytes become "trapped" in the circulation of the leg during periods of venous hyper-tension produced by sitting or standing. Studies of the plasma levels of neutrophil granule enzymes shows that these are increased during periods of venous hypertension, suggesting that this causes activation of the neutrophils. Investigation of the leucocyte surface ligands CD11b and CD62L shows that the more activated neutrophils and monocytes are sequestered during venous hypertension. Measurement of plasma levels of the soluble parts of the endothelial adhesion molecules VCAM, ICAM, and ELAM show that these are all elevated in patients with chronic venous disease compared to controls. Following 30 minutes of venous hypertension produced by standing, these levels are further increased. These data suggest that venous hypertension causes neutrophil and monocyte activation, which in turn causes injury to the endothelium. Chronic injury to the endothelium leads to a chronic inflammatory condition of the skin that we know clinically as lipodermatosclerosis. This is mediated by perivascular inflammatory cells, principally macrophages, in the skin microcirculation. These stimulate fibroblasts in the skin leading to tissue remodeling and laying down of fibrous tissue. Vascular endothelial growth factor stimulates proliferation of capillaries within the skin. Skin in this state has the potential to ulcerate in response to minor injury.

Chronic venous leg ulcers – role of topical zinc

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.

Venous ulcers of the lower limb: Where do we stand?

Full Text Available 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.

To evaluate the effectiveness and safety of isolated saphenofemoral junction ligation for the treatment of chronic venous leg ulcer in comparison to traditional stripping procedure. 36 patients (28 men and 8 women) with mean age of 42.3+-8.7, presented with a venous leg ulcer. After taking the full history, they underwent examination for presence of edema, cellulitis or local ulcer infection. The site and size of ulceration were recorded and ankle-brachial pressure index (ABPI) was measured, Venous valvular incompetence was assessed using Valsalva testand calf compression. Patients were divided into 2 groups. Group I, (n=10) assigned for long saphenous stripping, while group II (n=26) assigned for saphenofemoral ligationan and divided combined with ligation of major tributaries under local infiltration anesthesia. Mean operative time, postoperative complications and hospital stay were recorded. The study was carried out in Benha University Hospital, Egypt and Armed Forces Hospital, Southern Region, Khamis Mushayt, Sadi Arabia between January 2000 and December 2001. The mean operative time and the hospital stay were significantly (p<0.05) reduced in group II compared to group I. The postoperative complications were signficantly (x=7.5, p<0.05) reduced in group II. Ulcer healing started after 3 months in group II and six months in group I, but by 12 month, group II had significant (x=6.7, p<0.05) number of healed ulcers (n=22, 84.6%), compared to group I (n=7, 70%). The isolated ligation of of saphenofemoral junction is a minimally invasive, safe and effective modality for treatment of chronic leg ulcer, and being easily performed under local anesthesia and considerd to be a satisfactory procedure for treatment of leg ulcer in patients who are unfit for general anesthesia.

Venous leg ulcers are the most frequent form of wounds seen in patients. This article presents an overview on some practical aspects concerning diagnosis, differential diagnosis and treatment. Duplex ultrasound investigations are essential to ascertain the diagnosis of the underlying venous pathology and to treat venous refluxes. Differential diagnosis includes mainly other vascular lesions (arterial, microcirculatory causes), hematologic and metabolic diseases, trauma, infection, malignancies. Patients with superficial venous incompetence may benefit from endovenous or surgical reflux abolition diagnosed by Duplex ultrasound. The most important basic component of the management is compression therapy, for which we prefer materials with low elasticity applied with high initial pressure (short-stretch bandages and Velcro-strap devices). Local treatment should be simple, absorbing and not sticky dressings keeping adequate moisture balance after debridement of necrotic tissue and biofilms are preferred. After the ulcer is healed compression therapy should be continued in order to prevent recurrence. PMID:26236636

Wund-D.A.CH. is the umbrella organization of the various wound care societies in German-speaking countries. The present consensus paper on practical aspects pertinent to compression therapy in patients with venous leg ulcers was developed by experts from Germany, Austria, and Switzerland. In Europe, venous leg ulcers rank among the most common causes of chronic wounds. Apart from conservative and interventional wound and vein treatment, compression therapy represents the basis of all other therapeutic strategies. To that end, there are currently a wide variety of materials and systems available. While especially short-stretch bandages or multicomponent systems should be used in the initial decongestion phase, ulcer stocking systems are recommended for the subsequent maintenance phase. Another - to date, far less common - alternative are adaptive Velcro bandage systems. Medical compression stockings have proven particularly beneficial in the prevention of ulcer recurrence. The large number of treatment options currently available enables therapists to develop therapeutic concepts geared towards their patients' individual needs and abilities, thus resulting in good acceptance and adherence. Compression therapy plays a crucial role in the treatment of patients with venous leg ulcers. In recent years, a number of different treatment options have become available, their use and application differing among German-speaking countries. The present expert consensus is therefore meant to outline concrete recommendations for routine implementation of compression therapy in patients with venous leg ulcers. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

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. (paper)

Introduction 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. Methods and outcomes 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 interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2007 (BMJ 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). Results We found 80 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions 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, thromboxane alpha2 antagonists, zinc), peri-ulcer

Full Text Available Background and Design: Treatment of chronic venous ulcers of the lower extremity is still an important difficulty. The principal treatment of these ulcers includes compression therapy, local wound care and surgery. Unresponsiveness to these standard treatments is a frequent situation with negative effects on life quality and reductions in personal productivity. Therefore, there is a need for new applications to increase the effectiveness of treatment in treatment-resistant cases. In the present study, we retrospectively evaluated the results of topical application of amelogenin extracellular matrix protein in resistant venous ulcers. Materials and Methods: We analyzed the records of patients with treatment-resistant venous ulceration who were treated with amelogenin extracellular matrix protein between June 2011 and December 2012.. Results: 26 patients (21 male and 5 female with a total number of 28 ulcers (24 patients with 1 ulcer, 2 patients with two ulcers were evaluated. The patients were treated with topically applied amelogenin extracellular matrix protein and regional four bandage compression. Bandages were changed weekly. Each cure continued for six weeks. In fourteen patients (15 ulcers, we observed a complete healing by the end of the first cure. In another twelve cases (13 ulcers, the same period resulted with a reduction in wound diameter. We continued to the second cure for these patients. By the end of the second cure, complete healing was achieved in five cases (6 ulcers. Conclusion: Topical application of amelogenin extracellular matrix protein may be considered as an effective therapeutic choice for refractory venous ulcers.

To compare a four-layer bandage system with a two-layer system in the management of chronic venous leg ulceration, a prospective randomized open parallel groups trial was undertaken. In total, 112 patients newly presenting to leg ulcer services with chronic leg ulceration, screened to exclude the presence of arterial disease (ankle brachial pressure index ulceration other than venous disease, were entered into the trial. Patients were randomized to receive either four-layer (Profore) or two-layer (Surepress) high-compression elastic bandage systems. In all, 109 out of 112 patients had at least one follow-up. After 24 weeks, 50 out of 57 (88%) patients randomized to the four-layer bandage system with follow-up had ulcer closure (full epithelialization) compared with 40 out of 52 (77%) on the two-layer bandage, hazard ratio = 1.18 (95% confidence interval 0.69-2.02), p = 0.55. After 12 weeks, 40 out of 57 (70%) patients randomized to the four-layer bandage system with follow-up had ulcer closure compared with 30 out of 52 (58%) on the two-layer bandage, odds ratio = 4.23 (95% confidence interval 1.29-13.86), p = 0.02. Withdrawal rates were significantly greater on the two-layer bandage (30 out of 54; 56%) compared with the four-layer bandage system (8 out of 58; 14%), p bandaging system (15 out of 54; 28%) compared with four-layer bandaging (5 out of 54; 9%), p = 0.01. The higher mean cost of treatment in the two-layer bandaging system arm over 24 weeks ($1374 [ pound 916] vs. $1314 [ pound 876]) was explained by the increased mean number of bandage changes (1.5 vs. 1.1 per week) with the two-layer system. In conclusion, the four-layer bandage offers advantages over the two-layer bandage in terms of reduced withdrawal from treatment, fewer adverse incidents, and lower treatment cost.

The high incidence of venous leg ulcers and the difficult to give a complete healing involves in an increase of costs for National Health System. Main therapies to obtain a fast healing are compressive bandages, treatment of abnormal venous flow and in-situ-strategies of wound care. Negative pressure therapy does not conventionally used, because these systems not allow the use of compression bandages. Recently the development of ultraportable devices has improved the compliance and the results. Ten patients with venous chronic ulcer on the lower extremities were recruited for this study: all patients had venous leg ulcers from at least one year. We treated the patients with autologous partial thickness skin graft and subsequently we applied NANOVA device included in compressive bandage. We used NANOVA for fourteen days and after we made traditional medications. We submitted a questionnaire to evaluate the impact of dressing and NANOVA device in the quality of life of patients. The device contributed to the formation of granulation tissue and increased the success rate of autologous skin graft without limiting mobility of patient. In addition to this, we have been able to perform compression bandages thanks to small size of this device. Eight ulcers healed within 90 days of medication. We believe that ultraportable negative pressure systems are useful devices for treatment of venous leg ulcers because them allows to realize a compressive bandage without mobility limitations.

The prevalence of peripheral arterial disease in the general population is high, but the awareness of primary care providers of the disease process is low. The disease is not recognized by primary care providers. Early recognition and treatment of venous diseases that progress to postphlebotic syndrome, such as after a deep vein thrombosis, will prevent venous ulcers that add considerable expense to the health care system. Vascular assessment, including routine ABI measurement of patients who are in risk categories for vascular disease will identify those patients so that prevention programs can be put into place early. Major contributions to the understanding and management of leg ulcers and wound healing have been made in the last decade. However, there is still confusion as to the exact mechanism behind ulcer development and the best method to manage, cure,and prevent these ulcers has yet to be found.

History of venous leg ulcers.

To retrieve the history of venous ulcers and of skin lesions in general, we must go back to the appearance of human beings on earth. It is interesting to note that cutaneous injuries evolved parallel to human society. An essential first step in the pathogenesis of ulcers was represented by the transition of the quadruped man to Homo Erectus. This condition was characterized by a greater gravitational pressure on the lower limbs, with consequences on the peripheral venous system. Furthermore, human evolution was characterized by an increased risk of traumatic injuries, secondary to his natural need to create fire and hunt (e.g. stones, iron, fire, animal fighting). Humans then began to fight one another until they came to real wars, with increased frequency of wounds and infectious complications. The situation degraded with the introduction of horse riding, introduced by the Scites, who first tamed animals in the 7th century BC. This condition exhibited iliac veins at compression phenomena, favouring the venous stasis. With time, man continued to evolve until the modern age, which is characterized by increased risk factors for venous wounds such as poor physical activity and dietary errors (1, 2).

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.

2005-08-01

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.

However, compared with the NIVI group, the healing time for patients who actually received IVAS was marginally lower (5.8 ± 3.6 weeks, P = 0.075) and final VCCS was significantly lower (2.4 ± 2.9, P = 0.031). Veins that received IVI and IVAS remained patent and the associated ulcers were healed (100%). The small sample size and retrospective design limit the strength of the conclusions but the findings suggest that further studies are needed to define the exact role of IVI including angioplasty/stenting for patients with chronic venous ulcers.

Surgical techniques to address various components of chronic venous disease are rapidly evolving. Their efficacy and generally good results in treating superficial venous reflux (SVR) have been documented and compared in patients presenting with pain and swelling. A growing amount of literature is now available suggesting their efficacy in patients with venous leg ulcer (VLU). This review attempts to summarize the efficacy and limitations of commonly used venous interventions in the treatment of SVR and incompetent perforator veins (IPVs) in patients with VLU. A systematic review of the published literature was performed. Two different searches were conducted in MEDLINE, Embase, and EBSCOhost to identify studies that examined the efficacy of SVR ablation and IPV ablation on healing rate and recurrence rate of VLU. In the whole review, 1940 articles were screened. Of those, 45 were included in the SVR ablation review and 4 in the IPV ablation review. Data were too heterogeneous to perform an adequate meta-analysis. The quality of evidence assessed by the Grading of Recommendations Assessment, Development, and Evaluation for the two outcomes varied from very low to moderate. Ulcer healing rate and recurrence rate were between 70% and 100% and 0% and 49% in the SVR ablation review and between 59% and 93% and 4% and 33% in the IPV ablation review, respectively. To explain those variable results, limitations such as inadequate diagnostic techniques, saphenous size, concomitant calf pump dysfunction, and associated deep venous reflux are discussed. Currently available minimally invasive techniques correct most venous pathologic processes in chronic venous disease with a good sustainable healing rate. There are still specific diagnostic and efficacy limitations that mandate proper match of individual patients with the planned approach. Copyright © 2017 Society for Vascular Surgery.

Uwe Wollina

2011-01-01

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

The study was aimed at comparatively assessing the efficacy of treatment for venous trophic ulcers at stages II-III of the wound process using special compression knee-length socks of the ULCER X kit (Sigvaris AG, St. Gallen, Switzerland) and long-stretch bandages Lauma. Compression therapy was included into the programme of outpatient treatment of forty 31-to-74-year-old patients presenting with trophic ulcers (stage II-III of the wound process) with an average area of 5,36±1,1 cm2. The Study Group consisting of 20 patients used compression knitted fabrics in the form of knee-length socks ULCER X and the comparison group (n=20) used long-stretch bandages Lauma. The obtained findings (6 months) demonstrated that using compression therapy exerted a positive effect on the process of healing of venous trophic ulcers, also proving advantages of compression therapy with the knee-length socks ULCER X that create an adequate level of pressure on the crus and maintain it in long-term daily use, reliably accelerating the healing of venous trophic ulcers as compared with elastic long-stretch bandages. The use of long-stretch elastic bandages in treatment of venous trophic ulcers turned out to be not only ineffective but fraught with a possibility of the development of various complications. During 6 months of follow up the patients using the special knee-length socks ULCER X were found to have 80 % of ulcers healed (16 patients), mainly within the first 2 months, whereas using elastic bandages resulted in only 30 % of healing (6 patients) by the end of the study. Along with it, we documented a considerable decrease in the malleolar circumference in the study group patients (from 30,05±0,78 to 28,35±0,86 cm) and in the control group from 31,2±30,35 to 30,25±0,75 cm), accompanied and followed by more than a two-fold increase in quality of life of the patients along all the parameters in the study group and a 1.4-fold increase in the control group patients.

To compare the proportion and rate of healing, pain, and quality of life of low-strength medical compression stockings (MCS) with traditional bandages applied for the treatment of recalcitrant venous leg ulcers. A single-center, randomized, open-label study was performed with consecutive patients. Sigvaris prototype MCS providing 15 mm Hg-25 mm Hg at the ankle were compared with multi-layer short-stretch bandages. In both groups, pads were placed above incompetent perforating veins in the ulcer area. The initial static pressure between the dressing-covered ulcer and the pad was 29 mm Hg and 49 mm Hg with MCS and bandages, respectively. Dynamic pressure measurements showed no difference. Compression was maintained day and night and changed every week. The primary endpoint was healing within 90 days. Secondary endpoints were healing within 180 days, time to healing, pain (weekly Likert scales), and monthly quality of life (ChronIc Venous Insufficiency Quality of Life [CIVIQ] questionnaire). Of 74 patients screened, 60 fulfilled the selection criteria and 55 completed the study; 28 in the MCS and 27 in the bandage group. Ulcers were recurrent (48%), long lasting (mean, 27 months), and large (mean, 13 cm2). All but one patient had deep venous reflux and/or incompetent perforating veins in addition to trunk varices. Characteristics of patients and ulcers were evenly distributed (exception: more edema in the MCS group; P = .019). Healing within 90 days was observed in 36% with MCS and in 48% with bandages (P = .350). Healing within 180 days was documented in 50% with MCS and in 67% with bandages (P = .210). Time to healing was identical. Pain scored 44 and 46 initially (on a scale in which 100 referred to maximum and 0 to no pain) and decreased within the first week to 20 and 28 in the MCS and bandage groups, respectively (P ulcers only. Our study illustrates the difficulty of bringing large and long-standing venous ulcers to heal. The effect of compression with MCS was

Complementary and alternative medicine for older adults with venous leg ulcer pain.

Tobón, Jeniffer

2010-11-01

Chronic pain management is an important, and often under-addressed, component in the care of older adults with venous leg ulcers (VLUs). Clinicians caring for older adults with VLUs must consider and address both the physiological and psychosocial aspects of chronic pain. Traditional pharmacological approaches to pain management are only part of the solution. One strategy is to adopt a more holistic approach to chronic pain management that includes complementary and alternative medicine (CAM) therapies. Unfortunately, there is a paucity of CAM research that focuses on the pain management of older adults with VLUs. Despite these limitations, pain management that includes discussion of relevant CAM modalities must be a priority for clinicians caring for older adults living with VLUs.

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. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Laser Doppler Flowmetry (LDF) and transcutaneous oximetry (TcpO2) are established methods for investigating cutaneous perfusion. To date, no study previously performed has compared data obtained from these 2 methodologies in cases of chronic cutaneous ulcers. Laser Doppler Flowmetry and TcpO2 were performed in 25 consecutive outpatients with chronic lower limb ulcers (group A, experimental; 9 women and 16 men; mean age 67 years [range, 52-81 years]) and 25 age- and sex-matched healthy control subjects (group B, control) enrolled for the study. Ulcer aetiologies included 12 peripheral arterial occlusive disease, 9 chronic venous insufficiencies, and 4 pressure ulcers. Data were analyzed with Shapiro-Wilk and Wilcoxon-Mann-Whitney tests. A statistically significant difference (P < .05) was found between LDF values of the 2 groups. No statistically significant differences were found between the 2 groups regarding the TcpO2 measurements. The data confirmed the soundness of LDF while investigating local perfusion in patients with chronic cutaneous ulcers. The same diagnostic accuracy was not obtained by means of TcpO2.

For effective compression therapy in patients with venous leg ulcers, sufficient pressure is essential. In everyday life, it is often the patients themselves who apply the compression bandages. Many of these patients have restriction in their movement and had been rarely trained adequately. Hence, there was the question of how efficient are the autonomously applied compression bandages of those patients. In all, 100 consecutive patients with venous leg ulcer were asked to apply compression bandages on their own leg. We documented both the achieved compression and formal criteria of correct performance. A total of 59 women and 41 men with an average age of 70.3 years were included in the study. Overall 43 patients were not able to apply a compression bandage because of physical limitations. The measured pressure values in the remaining 57 patients ranged between 6 and 93 mm Hg (mean 28.3 mm Hg). Eleven patients reached the prescribed effective compression pressure. Of these, formal errors were found in 6 patients, so that only 5 patients had correctly applied the compression bandages. Our data show that most patients with venous leg ulcers are not able to apply effective compression therapy with short-stretch bandages to themselves. Multilayer systems, adaptive compression bandages, and ulcer stocking systems today are possibly easier and more effective therapy options. Alternatively short-stretch bandages could be applied by trained persons but only under the control with pressure measuring probes.

This study was conducted to define bandage pressures that are safe and effective in treating leg ulcers of mixed arterial-venous etiology. In 25 patients with mixed-etiology leg ulcers who received inelastic bandages applied with pressures from 20 to 30, 31 to 40, and 41 to 50 mm Hg, the following measurements were performed before and after bandage application to ensure patient safety throughout the investigation: laser Doppler fluxmetry (LDF) close to the ulcer under the bandage and at the great toe, transcutaneous oxygen pressure (TcPo(2)) on the dorsum of the foot, and toe pressure. Ejection fraction (EF) of the venous pump was performed to assess efficacy on venous hemodynamics. LDF values under the bandages increased by 33% (95% confidence interval [CI], 17-48; P pressure ranges applied. At toe level, a significant decrease in flux of -20% (95% CI, -48 to 9; P bandage pressure >41 mm Hg. Toe pressure values and TcPo(2) showed a moderate increase, excluding a restriction to arterial perfusion induced by the bandages. Inelastic bandages were highly efficient in improving venous pumping function, increasing the reduced ejection fraction by 72% (95% CI, 50%-95%; P pressure of 21 to 30 mm Hg and by 103% (95% CI, 70%-128%; P ulceration, an ankle-brachial pressure index >0.5 and an absolute ankle pressure of >60 mm Hg, inelastic compression of up to 40 mm Hg does not impede arterial perfusion but may lead to a normalization of the highly reduced venous pumping function. Such bandages are therefore recommended in combination with walking exercises as the basic conservative management for patients with mixed leg ulcers. Copyright © 2012 Society for Vascular Surgery.

Despite the documented effect of compression therapy in clinical studies and its widespread prescription, treatment of venous leg ulcers is often prolonged and recurrence rates high. Data on provided compression therapy are limited. To assess whether home care nurses achieve adequate subbandage pressure when treating patients with venous leg ulcers and the factors that predict the ability to achieve optimal pressure. We performed a cross-sectional study from March 1, 2011, through March 31, 2012, in home care centers in 2 Danish municipalities. Sixty-eight home care nurses who managed wounds in their everyday practice were included. Participant-masked measurements of subbandage pressure achieved with an elastic, long-stretch, single-component bandage; an inelastic, short-stretch, single-component bandage; and a multilayer, 2-component bandage, as well as, association between achievement of optimal pressure and years in the profession, attendance at wound care educational programs, previous work experience, and confidence in bandaging ability. A substantial variation in the exerted pressure was found: subbandage pressures ranged from 11 mm Hg exerted by an inelastic bandage to 80 mm Hg exerted by a 2-component bandage. The optimal subbandage pressure range, defined as 30 to 50 mm Hg, was achieved by 39 of 62 nurses (63%) applying the 2-component bandage, 28 of 68 nurses (41%) applying the elastic bandage, and 27 of 68 nurses (40%) applying the inelastic bandage. More than half the nurses applying the inelastic (38 [56%]) and elastic (36 [53%]) bandages obtained pressures less than 30 mm Hg. At best, only 17 of 62 nurses (27%) using the 2-component bandage achieved subbandage pressure within the range they aimed for. In this study, none of the investigated factors was associated with the ability to apply a bandage with optimal pressure. This study demonstrates the difficulty of achieving the desired subbandage pressure and indicates that a substantial proportion of

Venous leg ulcers (VLU) are a prevalent and reoccurring type of complicated wound, turning as a considerable public healthcare issue, with critical social and economic concern. There are both medical and surgical therapies to treat venous leg ulcers; however, a cure does not yet exist. Mesenchymal stem cells (MSC) are capable and proved of accelerating wound healing in vivo and their study with human chronic wounds is currently awaited. MSCs are a promising source of adult progenitor cells for cellular therapy and have been demonstrated to differentiate into various mesenchymal cell lineages. They have a crucial and integral role in native wound healing by regulating immune response and inflammation. Improved understanding of the cellular and molecular mechanisms at work in delayed wound healing compels to the development of cellular therapy in VLU. This review focuses on the current treatment option of VLU and further emphasizing the role of MSCs in accelerating the healing process. With further understanding of the mechanism of action of these cells in wound improvement and, the involvement of cytokines can also be revealed that could be used for the therapeutic purpose for VLU healing. Clinical uses of MSCs have been started already, and induced MSCs are surely a promising tool or compelling therapy for VLU. Copyright © 2017 Tissue Viability Society. Published by Elsevier Ltd.

1991-01-01

The blood flow rate in subcutaneous adipose tissue was measured on the lower legs of 11 patients with chronic lower-leg venous insufficiency and ulceration and in eight age-matched control subjects for 12-20 h, under ambulatory conditions, using the 133Xe wash-out technique with portable Cadmium...... telluride (CdTe(Cl)) detectors. In both groups, the change from an upright to a supine position at the beginning of the night period elicited an instantaneous increment in the blood flow rate of 30-40% with a decrease in the central and local postural sympathetic vasoconstrictor activity. After...... approximately 1 h of sleep, a considerable increase in blood flow rate was seen in both patient and control groups which persisted for nearly 100 min. In the patient group, the mean increase was 137% compared to a mean increase of 68% in the control group (P less than 0.01). The blood flow then returned...

Compression bandaging is a major treatment of chronic venous ulcers. Its efficacy depends on the applied pressure, which is dependent on the skill of the individual applying the bandage. To improve the quality of bandaging by reducing the variability in compression bandage interface pressures, we changed elastic bandages into a customised version by marking them with circular ink stamps, applied when the stretch achieves an interface pressure between 35 and 45 mmHg. Repeated applications by 20 residents of the customised bandage and non-marked bandage to one smaller and one larger leg were evaluated by measuring the sub-bandage pressure. The results demonstrated that the target pressure range is more often attained with the customised bandage compared with the non-marked bandage. The customised bandage improved the efficacy of compression bandaging for venous ulcers, with optimal sub-bandage pressure. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Full Text Available Venous ulcers require complex treatment and are responsible for significant morbidity and mortality rates. This study aims at identifying aspects validated by the jury for the preparation of an assistance protocol for venous ulcer sufferers. It is a descriptive and quantitative research, with 39 professionals (30 nurses, 7 doctors and two physiotherapists, held at the Onofre Lopes University Hospital, between April and July/2010. Data collection began through a questionnaire checklist. Analysis was performed through Statistical Package for Social Science 15.0, assessing compliance with guidelines. Results were the compositional aspects of the protocol: assessment of patient and lesion history/documentation, wound care/perilesional skin, dressing suggestion, use of antibiotics and pain treatment, surgical treatment/medication, improving venous return and relapse prevention, patient referral, professional training and referral/counter-referral. It was concluded that to compose the protocol, aspects related to diagnosis, treatment and injury prevention must be considered.

The systemic host defence mechanisms, especially innate immunity, in venous leg ulcer patients are poorly investigated. The aim of the current study was to measure Candida albicans killing activity and gene expressions of pro- and anti-inflammatory cytokines and innate immune response regulators, TAM receptors and ligands of peripheral blood mononuclear cells separated from 69 venous leg ulcer patients and 42 control probands. Leg ulcer patients were stratified into responder and non-responder groups on the basis of wound healing properties. No statistical differences were found in Candida killing among controls, responders and non-responders. Circulating blood mononuclear cells of patients overexpress pro-inflammatory (IL-1α, TNFα, CXCL-8) and anti-inflammatory (IL-10) cytokines as well as TAM receptors (Tyro, Axl, MerTK) and their ligands Gas6 and Protein S compared with those of control individuals. IL-1α is notably overexpressed in venous leg ulcer treatment non-responders; in contrast, Axl gene expression is robustly stronger among responders. These markers may be considered as candidates for the prediction of treatment response among venous leg ulcer patients. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

In order to generate the subject matter of such information, a literature search and a secondary analysis of 27 transcripts of interviews, given by people living with chronic leg ulceration, were conducted. Both analyses show the complex impact of leg ulceration on every-day live. The dimensions competences in every-day live, knowledge, techniques and skills and the meaning of family were generated. The secondary analysis points out that family members are an important part of the supporting system and are concerned by effects of chronic disease as well. After long-lasting disease-experience people consider themselves as experts. They obtain special competences in dealing with their disease and judge their experience-based knowledge higher than the knowledge of healthcare professionals. The participants describe individual concepts about their disease. Medical knowledge constitutes just one source of knowledge among others. People know about alternative medicine and use it. They feel that the healthcare professionals do not take them seriously in most cases. Patient-centred information can be a guide to people suffering from venous leg ulceration and their family members, but also a support for healthcare professionals to reflect their professional behaviour and understanding.

The discovery of moist environment dressings as alternatives to the traditional treatments based on exposing wounds to air, opened new expectations for the care and treatment of chronic wounds. Over the years, these expectations have led to the availability of new moist environment dressings which have made it possible to improve the care provided to patients suffering this kind of wounds, as well as providing important reasons to weigh in terms of cost-benefit-effectiveness at the time of selecting which type of treatment should be employed. The lack of comparative analysis among traditional treatments and moist environment treatments for chronic wounds among patients receiving primary health care led the authors to perform an analysis comparing these aforementioned options of treatment on patients suffering venous leg ulcers or pressure ulcers. The authors designed a Randomized Clinical Trial involving patients receiving ambulatory care in order to compare the effectiveness and cost-benefit of traditional versus moist environment dressing during the treatment of patients suffering stage II or III pressure ulcers or venous leg ulcers. In this trial, variables related to effectiveness of both treatments, as well as their costs were analyzed. 70 wounds were included in this Randomized Clinical Trial, 41 were venous leg ulcers of which 21 received a moist environment treatment while 20 received traditional cure, the other 29 wounds were pressure ulcers of which 15 received moist environment dressings treatment and 14 received traditional dressings. No statistically significant differences were found among the defining variables for these lesions in either group under treatment. In the venous leg ulcer study group, the authors conclusions were an average of 18.13 days, 16.33 treatment sessions and a cost of 10,616 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with traditional treatment compared to an average of 18

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

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 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.

This case study describes treatment for a 52-year-old man with a recurrent venous leg ulcer using a collagen dressing with extracellular matrix. The patient was admitted to the wound care service for a 3-week-old recurrent venous ulcer. Treatment included application of a collagen dressing with extracellular matrix twice weekly or as needed by the patient; application of a secondary dressing (4 × 4 gauze); and coverage with an expandable netting or gauze using a conforming stretch gauze bandage and latex-free dressing retention tape. The initial venous leg ulcer in this patient required 10 weeks to achieve closure. Ninety-eight percent resolution of the recurrent ulcer had occurred within 4 weeks of treatment, with complete closure at 7 weeks. The average healing time for recurrent venous ulcers is reported in the literature to be longer than initial venous ulcers. In the case provided, collagen ECM dressings promoted complete wound healing in 49 days.

Full Text Available Evaluating tetanus immune status is not yet the usual clinical practice regarding patients with chronic ulcers or myasis. However, of 858 tetanus patients at Hospital Couto Maia (Salvador, Bahia, Brazil aged 1 year or above, 2 had pressure ulcers and 17 had chronic ulceration of the lower limbs where these skin lesions were the ports of entry for Clostridium tetani. In these 19 cases, the following predisposing factors were described: venous insufficiency (n=6, sickle cell anemia (n=2, Hansen's disease (n=1, malnutrition (n=1, diabetes mellitus (n=1, trauma (n=1 and unknown factors (n=7. In 6 other cases, in addition to the Hansen's disease patient, the port of entry for tetanus was the site of extraction of Tunga penetrans larvae. In these 25 cases, the majority of patients (68% were over 40 years old (17/25 and all of these patients stated that they had either not followed a tetanus toxoid vaccination regimen (19/25, or had partially completed such a regimen, or did not give precise information (6/25. Among the same series studied, over half (52% of the patients died (13/25. We conclude that tetanus prevention must be included in the treatment of chronic skin ulcer patients, vaccination coverage should be increased among older people, and strategies aimed at improving coverage for all age groups must be reviewed.

Can Wound Exudate from Venous Leg Ulcers Measure Wound Pain Status?: A Pilot Study.

Directory of Open Access Journals (Sweden)

Taichi Goto

Full Text Available We investigated the associations between the self-evaluated pain status and two pain biomarker candidates, nerve growth factor and S100A8/A9, in exudate from venous leg ulcer to finally develop an objective pain evaluation method. Patients with venous leg ulcer participated in this cross-sectional observational study conducted between April and October 2014 at two medical facilities. During routine wound care, each participant self-evaluated their pain status at each examination using the 10-point numerical rating scale (present pain intensity and the short-form McGill Pain Questionnaire 2 (continuous pain, intermittent pain, neuropathic pain, affective descriptors, and total score. Venous leg ulcer exudate sample was collected after wound cleansing. The nerve growth factor and S100A8/A9 concentrations in the venous leg ulcer exudate were measured by enzyme-linked immunosorbent assay and standardized according to the wound area. The association between each pain status and the two standardized protein concentrations was evaluated using Spearman's correlation coefficient. In 30 sample collected from 13 participants, the standardized nerve growth factor concentration was negatively correlated with continuous pain (ρ = -0.47, P = 0.01, intermittent pain (ρ = -0.48, P = 0.01, neuropathic pain (ρ = -0.51, P = 0.01, and total score (ρ = -0.46, P = 0.01. The standardized S100A8/A9 concentration was positively correlated with present pain intensity (ρ = 0.46, P = 0.03 and continuous pain (ρ = 0.48, P = 0.03. Thus, these two proteins may be useful for objective evaluation of wound pain in venous leg ulcer patients.

This study aimed to develop an alternative graduated compression bandage for the treatment of venous leg ulcers. Alternative bandage components were identified and assessed for optimal performance as a graduated multi-layer compression bandage. Subsequently the physical characteristics and clinical efficacy of the optimal bandage combination was prospectively examined. Ten healthy limbs were used to develop the optimal combination and 20 limbs with venous ulceration to compare the physical properties of the two bandage types. Subsequently 42 consecutive ulcerated limbs were prospectively treated to examine the efficacy of the new bandage combination. The new combination produced graduated median (range) sub-bandage pressures (mmHg) as follows: ankle 59 (42-100), calf 36 (27-67) and knee 35 (16-67). Over a seven-day period this combination maintained a comparable level of compression with the Charing Cross system, and achieved an overall healing rate at one year of 88%. The described combination should be brought to the attention of healthcare professionals treating venous ulcers as a possible alternative to other forms of multi-layer graduated compression bandages pending prospective, randomised clinical trials.

Drawbacks exist with the standard treatment (four-layer compression bandages) for venous leg ulcers. We have therefore compared the clinical effectiveness and cost-effectiveness of two-layer compression hosiery with the four-layer bandage for the treatment of such ulcers. We undertook this pragmatic, open, randomised controlled trial with two parallel groups in 34 centres in England and Northern Ireland. The centres were community nurse teams or services, family doctor practices, leg ulcer clinics, tissue viability clinics or services, and wound clinics. Participants were aged 18 years or older with a venous leg ulcer and an ankle brachial pressure index of at least 0·8, and were tolerant of high compression. We randomly allocated participants (1:1) to receive two-layer compression hosiery or a four-layer bandage, using a remote randomisation service and prevalidated computer randomisation program. Participants were stratified by ulcer duration and ulcer area with permuted blocks (block sizes four and six). The primary endpoint was time to ulcer healing, with a maximum follow-up of 12 months. Although participants and health-care providers were not masked to treatment allocation, the primary endpoint was measured by masked assessment of photographs. Primary analysis was intention to treat with Cox regression, with adjustment for ulcer area, ulcer duration, physical mobility, and centre. This trial is registered with the ISRCTN register, number ISRCTN49373072. We randomly allocated 457 participants to the two treatment groups: 230 to two-layer hosiery and 227 to the four-layer bandage, of whom 453 (230 hosiery and 223 bandage) contributed data for analysis. Median time to ulcer healing was 99 days (95% CI 84-126) in the hosiery group and 98 days (85-112) in the bandage group, and the proportion of ulcers healing was much the same in the two groups (70·9% hosiery and 70·4% bandage). More hosiery participants changed their allocated treatment (38·3% hosiery vs 27�

People with chronic venous disease are at high risk for developing venous leg ulcers. Inflammation is posited as a pathological factor for this chronic condition as evidenced by persistently elevated skin temperature. As part of a larger trial to test the effects of a cooling regimen on leg ulcer prevention, the objective of this preliminary study was to evaluate the first 30 days of intense daily cooling. Compared to a placebo control cuff, a gel cuff applied to the most severely affected lower leg skin for 30 min daily showed no statistically significant differences between temperatures taken in the home at baseline compared to those measured at the 1 month follow up visit. There were also no differences in temperatures noted between the two groups, although the temperatures in the treatment group were lower 30 min after treatment, an indication of adherence. There was no discernable decrease or increase in temperature at a given time point during the 30 day treatment period compared to the control group. It may be better to have patients monitor skin temperature on a daily basis and then apply the cuff as necessary, rather than requiring daily cooling based on baseline measurement. This "prn" approach may provide a sufficient cooling milieu to prevent escalation of inflammation and thwart ulcer occurrence or recurrence. Clinical trials registration #NCT01509599.

Aim This randomized clinical trial was conducted 2008 – 2009 to investigate a cryotherapy (cooling) gel wrap applied to lower leg skin affected by chronic venous disorders to determine whether therapeutic cooling improves skin microcirculation. Impaired skin microcirculation contributes to venous leg ulcer development, thus new prevention therapies should address the microcirculation to prevent venous leg ulcers. Data Sources Sixty participants (n = 30 per group) were randomized to receive one of two daily 30-minute interventions for four weeks. The treatment group applied the cryotherapy gel wrap around the affected lower leg skin, or compression and elevated the legs on a special pillow each evening at bedtime. The standard care group wore compression and elevated the legs only. Laboratory pre- and post-measures included microcirculation measures of skin temperature with a thermistor, blood flow with a laser Doppler flowmeter, and venous refill time with a photoplethysmograph. Review methods Data were analysed using descriptive statistics, paired t-tests or Wilcoxon signed ranks tests, logistic regression analyses, and mixed model analyses. Results Fifty-seven participants (treatment = 28; standard care = 29) completed the study. The mean age was 62 years, 70% female, 50% African American. In the final adjusted model, there was a statistically significant decrease in blood flow between the two groups (−6.2[−11.8; −0.6], P = 0.03). No statistically significant differences were noted in temperature or venous refill time. Conclusion Study findings suggest that cryotherapy improves blood flow by slowing movement within the microcirculation and thus might potentially provide a therapeutic benefit to prevent leg ulcers.

A number of leg ulcer specialist/tissue viability specialists from across the UK were invited to evaluate PICO (Smith and Nephew, Hull) as a treatment for venous leg ulcers also in conjunction with a variety of compression bandages and garments. Patients across 5 sites had PICO applied in conjunction with compression therapy. This group of treating clinicians were then asked to give feedback on the outcome of the patients on whom they had used the new device. All feedback was recorded at a meeting and this was used to create a guideline for use.

Apart from compression therapy, physical therapy has scarcely been evaluated in the treatment of chronic venous disorders (CVDs). Spa treatment is a popular way to administer physical therapy for CVDs in France, but its efficacy has not yet been assessed in a large trial. The objective was to assess the efficacy of spa therapy for patients with advanced CVD (CEAP clinical classes C4-C5). This was a single-blind (treatment concealed to the investigators) randomized, multicenter, controlled trial (French spa resorts). Inclusion criteria were primary or post-thrombotic CVD with skin changes but no active ulcer (C4a, C4b, or C5). The treated group had the usual 3-week spa treatment course soon after randomization; the control group had spa treatment after the 1-year comparison period. All patients continued their usual medical care including wearing compression stockings. Treatment consisted of four balneotherapy sessions per day for 6 days a week. Follow-up was performed at 6, 12 and 18 months by independent blinded investigators. The main outcome criterion was the incidence of leg ulcers at 12 months. Secondary criteria were a modified version of the Venous Clinical Severity Score, a visual analog scale for leg symptoms, and the Chronic Venous Insufficiency Questionnaire 2 and EuroQol 5D quality-of-life autoquestionnaires. Four hundred twenty-five subjects were enrolled: 214 in the treatment group (Spa) and 211 in the control group (Ctr); they were similar at baseline regarding their demographic characteristics, the severity of the CVD, and the outcome variables. At 1 year, the incidence of leg ulcers was not statistically different (Spa: +9.3%; 95% confidence interval [CI], +5.6 - +14.3; Ctr: +6.1%; 95% CI, +3.2 - +10.4), whereas the Venous Clinical Severity Score improved significantly in the treatment group (Spa: -1.2; 95% CI, -1.6 - -0.8; Ctr: -0.6; 95% CI, -1.0 - -0.2; P = .04). A significant difference favoring spa treatment was found regarding symptoms after 1

To describe the study protocol for a study of the effectiveness of an internet-based learning program on venous leg ulcer nursing care (eVLU) in home health care. The prevalence of venous leg ulcers is increasing as population age. The majority of these patients are treated in a municipal home healthcare setting. However, studies show nurses' lack of knowledge of ulcer nursing care. Quasi-experimental study with pre- and postmeasurements and non-equivalent intervention and comparison groups. During the study, nurses taking care of patients with a chronic leg ulcer in home health care in one Finnish municipality will use the eVLU. Nurses working in home health care in another Finnish municipality will not use it providing standard care. Nurses will complete three questionnaires during the study and they will also be observed three times at patients' homes. Nurses' perceived and theoretical knowledge is the primary outcome of the study. Funding for this study was received from the Finnish Foundation for Nursing Education in 2014. Data from this study will provide information about the effectiveness of an internet-based educational program. After completing the program nurses will be accustomed to using internet-based resources that can aid them in the nursing care of patients with a VLU. Nurses will also have better knowledge of VLU nursing care. This study is registered with the International Clinical Trials Registry, identifier NCT02224300. © 2015 John Wiley & Sons Ltd.

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.

Introduction The aim of the research was to compare the dynamics of venous ulcer healing when treated with the use of compression stockings as well as original two- and four-layer bandage systems. Material and methods A group of 46 patients suffering from venous ulcers was studied. This group consisted of 36 (78.3%) women and 10 (21.70%) men aged between 41 and 88 years (the average age was 66.6 years and the median was 67). Patients were randomized into three groups, for treatment with the ProGuide two-layer system, Profore four-layer compression, and with the use of compression stockings class II. In the case of multi-layer compression, compression ensuring 40 mmHg blood pressure at ankle level was used. Results In all patients, independently of the type of compression therapy, a few significant statistical changes of ulceration area in time were observed (Student’s t test for matched pairs, p ulceration area in each of the successive measurements was observed in patients treated with the four-layer system – on average 0.63 cm2/per week. The smallest loss of ulceration area was observed in patients using compression stockings – on average 0.44 cm2/per week. However, the observed differences were not statistically significant (Kruskal-Wallis test H = 4.45, p > 0.05). Conclusions A systematic compression therapy, applied with preliminary blood pressure of 40 mmHg, is an effective method of conservative treatment of venous ulcers. Compression stockings and prepared systems of multi-layer compression were characterized by similar clinical effectiveness. PMID:22419941

Full Text Available A 75-year-old woman was admitted to our outpatient clinic with a three-year history of a painless, nonhealing ulcer located on the left lower leg. She had no response to previous therapy with local wound care. Skin examination revealed an ulcer 2.7 x 3.7 cm in size, and the surrounding skin showed minimal erythema. The surface of the ulcer demonstrated shiny granulation tissue. Biopsy of the ulcer edge and base showed basal cell carcinoma. Venous Doppler ultrasonography and dermatological examination did not reveal chronic venous insufficiency. Basal cell carcinomas rarely arise from previous long-term ulcers or developing de novo. We suggest that patients who develop non-healing leg ulcers, should be examined for basal cell carcinoma.

 The present study sought to estimate the hemodynamic effects inside wounds after applying infrared thermography. Clinical results were analyzed to evaluate any correspondence with hemodynamic events occurring inside the wounds. Group 1 consisted of 20 patients with venous leg ulcers (12 women, 8 men). Patients from group 1 received 1 high-voltage stimulation (HVS) procedure. Group 2 consisted of 23 patients (16 women, 7 men). Patients from group 2 received 1 ultrasound (US) procedure. Group 3 consisted of 21 patients (13 women, 8 men). Patients from group 3 received 1 low-level laser therapy (LLLT) procedure. Group 4 consisted of 23 patients (15 women, 8 men). Patients from group 4 received 1 compression therapy (CT) procedure. Group 5 consisted of 19 patients (11 women, 8 men). Patients from group 5 received 1 quasi-CT procedure. Infrared thermography was used to monitor arterial hemodynamic effects for each ulcer. Infrared thermography, based on analysis of wound surface temperatures, was used to reflect normal or abnormal arterial circulation in capillaries. The average and maximal temperatures before and after each physical procedure were measured 5, 10, 15, and 30 minutes afterward. The application of HVS and LLLT did not change the temperature inside the wounds. A significant temperature increase was noted after application of US and CT. The quasi-CT induced a thermal effect (only for a few minutes), but was not as intense as the effect of the compression stockings. The measurements showed a prolonged and steady thermal effect. The hemodynamic effect (improvement of arterial microcirculation inside the venous leg ulcer) is one of the most significant biophysical mechanisms of healing after clinically efficient compression therapy. Hemodynamic reactions are not basic mechanisms of high voltage stimulation and ultrasound therapy during the healing of venous leg ulcers. Computed thermography is a simple and useful tool to measure hemodynamic

Leg ulcers are a burden to patients, their families and society. The second most common cause of chronic leg ulcers is the mixed arterio-venous type. An 80-year-old female patient presented to our department due to painful enlarging chronic leg ulcer of mixed arteriovenous origin on her left lower leg. She suffered from peripheral arterial occlusive disease stage I and chronic venous insufficiency Widmer grade IIIa, and a number of comorbidities. The aim of our ulcer treatment was a complete and stable wound closure that was hampered by arterial occlusion, exposed tendon, and renal insiffuciency. To improve the prognosis for ulcer surgery, we performed percutaneous transluminal angioplasty, transcutaneous CO 2 and deep ulcer shaving. The wound was closed by sandwich transplantation using elastin-collagen dermal template and meshed split skin graft. She had a 100% graft take with rapid reduction of severe wound pain. Complex approaches are necessary, to gain optimum results in leg ulcer therapy in mixed leg ulcers. Therapeutic nihilism should be abandonend.

Compression for the management of venous leg ulcers: which material do we have?

Science.gov (United States)

Partsch, Hugo

2014-05-01

Compression therapy is the most important basic treatment modality in venous leg ulcers. The review focusses on the materials which are used: 1. Compression bandages, 2. Compression stockings, 3. Self-adjustable Velcro-devices, 4. Compression pumps, 5. Hybrid devices. Compression bandages, usually applied by trained staff, provide a wide spectrum of materials with different elastic properties. To make bandaging easier, safer and more effective, most modern bandages combine different material components. Self-management of venous ulcers has become feasible by introducing double compression stockings ("ulcer kits") and self-adjustable Velcro devices. Compression pumps can be used as adjunctive measures, especially for patients with restricted mobility. The combination of sustained and intermittent compression ("hybrid device") is a promising new tool. The interface pressure corresponding to the dosage of compression therapy determines the hemodynamic efficacy of each device. In order to reduce ambulatory venous hypertension compression pressures of more than 50 mm Hg in the upright position are desirable. At the same time pressure should be lower in the resting position in order to be tolerated. This prerequisite may be fulfilled by using inelastic, short stretch material including multicomponent bandages and cohesive surfaces, all characterized by high stiffness. Such materials do not give way when calf muscles contract during walking which leads to high peaks of interface pressure ("massaging effect"). © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Ultrasonography of Skin Changes in Legs with Chronic Venous Disease.

Science.gov (United States)

Caggiati, A

2016-10-01

In daily practice, ultrasonography (US) is used only to designate the location and pattern of venous lesions. Skin US is not performed between routine venous investigations. Skin morphology is evaluated by the same probes used for routine Duplex evaluation of superficial veins. US findings from evident skin lesions are comparatively evaluated with those from the surrounding apparently normal skin and from the contralateral leg. Inflammation and dermal edema can be found in the apparently normal skin of C2 legs. Swollen legs show thickening of the subcutaneous layer as a result of diffuse soaking or anechoic cavities, with or without dermal edema. Chronic hypodermitis is characterized by inflammatory edema in initial phases, and by liposclerosis in advanced cases. Recrudescence of inflammation provokes focal rarefactions of the subcutaneous layer, possibly related to ulcer opening. In legs with venous disorders, sonography refines clinical evaluation of the skin and may reveal changes not highlighted by inspection. Some of these changes could require further investigation because they have not yet been explained or described. Skin sonography should improve knowledge of the natural history of skin changes, as well as contribute to a better grading of venous diseases severity In particular, US evidence of cutaneous and subcutaneous changes in C2 legs should be considered to stratify the treatment in C2 legs, by identifying those in which varicose veins are not simply a cosmetic problem.

Efficacy and safety of the use of platelet-rich plasma to manage venous ulcers.

Science.gov (United States)

Escamilla Cardeñosa, Manuel; Domínguez-Maldonado, Gabriel; Córdoba-Fernández, Antonio

2017-05-01

The aim of this study was to analyse the efficacy and safety of using platelet rich in growth factor (PRGF) as a local treatment for venous ulcers. In a clinical trial 102 venous ulcers (58 patients) were randomly assigned to the study group (application of PRGF) or the control group (standard cure with saline). For both groups the healed area was calculated before and after the follow up period (twenty-four weeks). The Kundin method was used to calculate the healed area (Area = Length × Width × 0.785). Pain was measured at the start and end of treatment as a secondary variable for each group by record obtained by means of self-evaluation visual analogue scale. The average percentage healed area in the platelet rich plasma group was 67.7 ± 41.54 compared to 11.17 ± 24.4 in the control group (P = 0.001). Similarly, in the experimental group a significant reduction in pain occurred on the scale (P = 0.001). No adverse effects were observed in either of the two treatment groups. The study results reveal that application of plasma rich in platelets is an effective and safe method to speed up healing and reduce pain in venous ulcers. Copyright © 2016 Tissue Viability Society.

[Surgical treatment of varices at the stage of trophic disorders in chronic venous insufficiency].

Science.gov (United States)

Ludin, A; Ammann, J

1991-01-01

Most ulcers of the lower limbs are caused by existing chronic venous insufficiency. Later on, true social and professional problems will arise, with serious economic and psychological consequences not only for the patient himself, but for the community as well, such as huge medical costs--hence the importance of prevention and treatment, which must in no case be purely symptomatic. The ligation of the arch and of the perforating veins and stripping of the affected vein are part of the classical management of varices. These procedures can may prove to be virtually impossible in case of chronic venous insufficiency, if the patient also presents with subcutaneous liposclerosis or atrophy in an already pregangrenous skin. This preulcerous stage can be aggravated later on if the requirements for surgical repair are not met. Necrosis can then occur, if too aggressive surgery directly or indirectly injures the microcirculatory system of the damaged skin. Omitted or undesirable acts are dangerous at the stage of trophic disorders and surgery may fail to reach its aim, which of course would be to definitively and quickly eliminate the varicose disease.

To compare the clinical and cost-effectiveness of two different compression bandages for the healing of venous leg ulcers. A pragmatic, randomised controlled trial with an economic evaluation. Community, district nurse-led services; community leg ulcer clinics; hospital leg ulcer clinics with community outreach. A range of urban and rural settings in England and Scotland. Patients with a venous leg ulcer of at least 1-week's duration, at least 1 cm in length or width and an ankle:brachial pressure index of at least 0.8. The four-layer bandage (4LB) (which is multilayer elastic compression) compared with the short-stretch bandage (SSB) (multilayer, inelastic compression). The primary end-point was complete healing of all the ulcers on the trial leg. Secondary outcomes were the proportion of patients healed at 12 and 24 weeks, rate of recurrence, costs of leg ulcer treatment and quality of life. Between April 1999 and December 2000 the trial recruited 387 people aged from 23 to 97 years at trial entry. The majority of patients in this trial (82%; 316/387) had a reference ulcer of area bandage groups, the distribution of the cumulative times to healing of individuals in the two trial groups was compared using the log-rank test. The difference in the distribution of cumulative healing times between the individuals in the two groups was not statistically significant at the 5% level. Adjusting for the effects of variables which may influence healing (centre, baseline ulcer area, duration, episodes, ankle mobility, weight) in a Cox proportional hazards model, a statistically significant treatment effect in favour of the 4LB was identified. At any point in time, the probability of healing for individuals in the SSB treatment arm is significantly lower than that for people treated with the 4LB. Our base case economic analysis showed that the 4LB is the dominant strategy, that is, it is associated with a greater health benefit and lower costs than the SSB, although the

Etiological diagnosis of leg ulcers must be the first step of treatment, even if we know that veinous disease is often present. We can build a clinical decisional diagram, which helps us to understand and not forget the other causes of chronic wounds and choose some basic examination, like ultrasound and histological findings. This diagnosis helps to choose the right treatment in order to cure even the oldest venous ulcers. Educational programs should be improved to prevent recurrence.

Impact of non-adherent Ibuprofen foam dressing in the lives of patients with venous ulcers

Directory of Open Access Journals (Sweden)

GERALDO MAGELA SALOMÉ

Full Text Available ABSTRACT Objective : to evaluate pain in patients with lower limb venous ulcer who used non-adherent Ibuprofen foam dressing (IFD. Methods : 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. Results : 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. Conclusion : non-adherent Ibuprofen foam dressing is effective in reducing the pain of patients with venous ulcers.

A novel, non-invasive diagnostic clinical procedure for the determination of an oxygenation status of chronic lower leg ulcers using peri-ulceral transcutaneous oxygen partial pressure measurements: results of its application in chronic venous insufficiency (CVI).

Science.gov (United States)

Barnikol, Wolfgang K R; Pötzschke, Harald

2012-01-01

The basis for the new procedure is the simultaneous transcutaneous measurement of the peri-ulceral oxygen partial pressure (tcPO(2)), using a minimum of 4 electrodes which are placed as close to the wound margin as possible, additionally, as a challenge the patient inhales pure oxygen for approximately 15 minutes. In order to evaluate the measurement data and to characterise the wounds, two new oxygen parameters were defined: (1) the oxygen characteristic (K-PO(2)), and (2) the oxygen inhomogeneity (I-PO(2)) of a chronic wound. The first of these is the arithmetic mean of the two lowest tcPO(2) measurement values, and the second is the variation coefficient of the four measurement values. Using the K-PO(2) parameter, a grading of wound hypoxia can be obtained. To begin with, the physiologically regulated (and still compensated) hypoxia with K-PO(2) values of between 35 and 40 mmHg is distinguished from the pathological decompensated hypoxia with K-PO(2) values of between 0 and 35 mmHg; the first of these still stimulates self-healing (within the limits of the oxygen balance). The decompensated hypoxia can be (arbitrarily) divided into "simple" hypoxia (Grade I), intense hypoxia (Grade II) and extreme hypoxia (Grade III), with the possibility of intermediate grades (I/II and II/III).Measurements were carried out using the new procedure on the skin of the right inner ankle of 21 healthy volunteers of various ages, and in 17 CVI (chronic venous insufficiency) wounds. Sixteen of the 17 CVI wounds (i.e., 94%) were found to be pathologically hypoxic, a state which was not found in any of the healthy volunteers. The oxygen inhomogeneity (I-PO(2)) of the individual chronic wounds increased exponentially as a function of the hypoxia grading (K-PO(2)), with a 10-fold increase with extreme hypoxia in contrast to a constant value of approximately 14% in the healthy volunteers. This pronounced oxygen inhomogeneity explains inhomogeneous wound healing, resulting in the so

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. The studies considered in this review were of varying and partly low

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.

An increasing numbers of physical treatment options are available for chronic leg ulcer. In this review article, compression therapy, therapeutic ultrasound, negative pressure therapy, extracorporeal shock wave therapy, electrostimulation therapy, electromagnetic therapy, photodynamic therapy, water-filtered infrared-A-radiation and hydrotherapy are discussed in terms of their practical applications and the underlying evidence. With the exception of compression therapy for most of these treatments, good scientific data are not available. However this is a widespread problem in the treatment of chronic wounds. Nevertheless, several of the described methods such as negative pressure therapy represent one of the gold standards in practical treatment of patients with chronic leg ulcers. Although the use of physical treatment modalities may improve healing in patients with chronic leg ulcers, the diagnosis and treatment of the underlying causes are essential for long-lasting success.

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.

Leg ulcers due to hyperhomocysteinemia

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.

Marjolin’s ulcer in chronic wounds – review of available literature

Directory of Open Access Journals (Sweden)

Dariusz Bazaliński

2017-09-01

Full Text Available Marjolin’s ulcer is a rare, aggressive skin cancer developing in scar tissue, chronic ulcers and areas affected by inflammations. Its incidence is estimated to range from 1% to 2% of all burn scars. It most frequently takes the form of squamous cell carcinoma which sometimes is diagnosed during examination of lesions developing in scars and hard-to-heal chronic wounds (pressure sores, leg ulcers. Therapeutic management of Marjolin’s ulcer requires well-designed treatment plan to ensure optimal medical care and good quality of life for the patient. The high risk of metastases and damage to the structure of vitally important organs determines the need for early diagnosis and prompt surgical intervention with supplementary therapy. The purpose of the study was to examine etiopathogenesis of Marjolin’s ulcer and principles of its treatment. The authors focused on the aspect of malignant degeneration in chronic wounds (leg ulcers, pressure sores as a very rare, aggressive form of Marjolin’s ulcer. A review of the available literature on the issue of Marjolin ulcers was conducted using the key words; Marjolin ulcers, pressure sore, chronic wound. Malignant degeneration in chronic wounds is a very rare aggressive form of Marjolin ulcer. Increased oncological alertness should be displayed by nursing and medical personnel taking care of patients with chronic wounds.

Full Text Available Chronic wounds like venous calf and diabetic foot ulcers are frequently contaminated and colonized by bacteria and it remains unclear whether there is sufficient expression of defensins and recruitment of epidermal Langerhans cells in the margin of ulcer compared to normal skin. The aim of this study was to examine immunohistochemically the expression of β-defensin-2 (hBD2, GM-CSF, VEGF growth factors and accumulation of CD1a+ Langerhans cells (LC in epidermis from chronic skin ulcers and to compare it to normal skin from the corresponding areas. Studies were carried out in 10 patients with diabetic foot, 10 patients with varicous ulcers of the calf and 10 patients undergoing orthopedic surgery (normal skin for control. Biopsy specimens were immunostained using specific primary antibodies, LSAB+ kit based on biotin-avidinperoxidase complex technique and DAB chromogen. Results were expressed as a mean staining intensity. Statistical analysis of staining showed significantly higher staining of hBD2 in both normal and ulcerated epidermis from foot sole skin compared to calf skin (normal and ulcerated, p<0.05. Chronic ulcers showed the same expression of hBD2 as normal skin. There was significantly lower accumulation of CD1a+ LC in normal epidermis from foot sole skin compared to normal calf skin (p<0.05. Accumulation of CD1a+ LC and GM-CSF upregulation at the border area of diabetic foot ulcer and reduction of LC concentration at the margin of venous calf ulcer compared to normal skin were observed. It seems that normal calf and sole epidermis is, unlike in the mechanisms of innate immunity, influenced by the different keratinocyte turnover and bacterial flora colonizing these regions. Insufficient upregulation of hBD2 in both diabetic foot and venous calf ulcers may suggest the pathological role of this protein in the chronicity of ulcers.

To evaluate self-esteem and body image in patients with venous leg ulcers (VLUs). A multicenter, prospective, descriptive, analytical, clinical study. A nursing care and education center of a university hospital, a health center, and an outpatient wound care clinic in Brazil. Fifty-nine consecutive adult patients with VLUs and Doppler ankle-brachial index ranging from 0.8 to 1.0 were recruited for the study. Exclusion criteria were mixed ulcers, arterial ulcers, and diabetic foot ulcers. A questionnaire assessing sociodemographic and clinical characteristics of patients, the Brazilian version of the Body Investment Scale, and the Rosenberg Self-esteem (RSE)/UNIFESP-EPM (São Paulo da Universidade Federal de São Paulo-Escola Paulista de Medicina) scale were administered to all patients. Most participants were women, aged between 60 and 70 years, and smokers; 33 (56%) were divorced, widowed, or single, and 26 (44%) were married. The patients had the ulcer for a mean of 5.42 years. Exudate and foul odor were present in most cases. Twenty-one ulcers (36%) measured 29 cm or less in surface area, and 17 (29%) ulcers measured between 30 and 49 cm (mean, 3.39 cm). The mean RSE score was 22.66, indicating low self-esteem. The mean Body Investment Scale total score was 27.49, and the scores on the body image and body touch subscales were also low, indicating negative feelings about the body. Patients with VLUs had low self-esteem and negative feelings about their bodies.

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.

Objectives: We conducted an analysis of correlation between histological grading of chronic gastritis and the presence of H. pylori infection to investigate if H. pylori influences histological severity of chronic gastritis in Korean patients with peptic ulcers. Methods: Gastroscopic antral biopsy specimens and peripheral venous blood were taken from 80 patients with gastric or duodenal ulcers. H. pylori was identified microscopically in sections with Giemsa staining and quantitative grading of cultured H. pylori was reported on a scale 0 to 3. The histopathological features of biopsy specimens were reported according to the Sydney classification of chronic gastritis. Serum gastritis and pepsinogen concentrations were measured by radioimmunoassay. Results: H. pylori was identified in 62.5% (20 of 32 GU, 30 of 48 DU) of the study group. Gastric clonization rate of H. pylori did not increased with age. Forty of 50 biopsy specimens with H. pylori and also 23 of 30 biopsy specimens without H. pylori showed active chronic gastritis. There was no significant correlation overall between the presence of H. pylori and histological grading of chronic gastritis, including activity, and also no association was found between the quantitative grading of H. pylori and the histological grading of chronic gastritis. With and without H. pylori, a mean of serum gastritis concentration (79.4±43.0 pg/ml and 80.2±31.9 pg/ml) showed no significant difference, but a mean of serum pepsinogen concentration (87.7±41.6 ng/ml and 119±34.4 ng/ml) showed significant difference between the populations with and without H. pylori (p=0.001) Conclusions: The influence of H. pylori on histological grading of chronic gastritis in Korean is less than that in prior studies of Western countries, and further investigation of pathogenesis of H. pylori in chronic gastritis and peptic ulceration is necessary.

Objective: To investigate the levels of telomerase activity in chronic radiation ulcers of human skin and the possible relationship between the enzyme and cancer transformation. Method: Using nonisotopic telomere repeat amplification protocol (TRAP), detections were performed in 20 cases of chronic radiation ulcers of human skin, 5 cases of normal skin tissues and 5 cases of carcinoma. Results: The positive rates for telomerase activity were 30.0%(6/20), 0(0/5) and 100%(5/5) in chronic radiation ulcers of human skin, normal skin and carcinoma, respectively. The telomerase activity in radiation ulcer was weaker than in carcinoma. Conclusion: The telomerase activity assay might be used as a marker for predicting the prognosis and the effect of treatment in chronic radiation ulcer of human skin

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.

AA amyloidosis, secondary to inflammatory chronic diseases like rheumatoid arthritis, is often complicated by renal failure. Chronic inflammatory dermatoses constitute rare causes of AA amyloidosis. We describe two cases of AA amyloidosis discovered after renal failure in patients presenting leg ulcers for several years. AL amyloidosis was suspected in both cases because of a history of monoclonal gammopathy in one patient and of plasmocytoma in the other. The diagnosis of AA amyloidosis was confirmed on renal histology through the detection of AA antibodies in amyloid deposits. No extrarenal amyloidosis was seen in either patient and there were no inflammatory diseases other than chronic leg ulcers. AA amyloidosis is caused by serum amyloid protein A (SAA), a reactive inflammatory protein. AA amyloidosis is thus caused by chronic inflammatory diseases, but only rarely by cutaneous inflammatory diseases. To our knowledge, the literature contains only seven other published cases of AA amyloidosis secondary to chronic leg ulcers. A review of the literature does not indicate whether cure of ulcers has any effect on the accompanying renal failure. We imagine that AA amyloidosis secondary to leg ulcer is in fact under-diagnosed. However, since the first specific treatment for AA amyloidosis is currently being evaluated by the Food and Drug Administration, it is essential that this serious complication of chronic leg ulcers be widely recognised.

Changes in gastroduodenal blood flow have been implicated in the pathogenesis of duodenal ulcer. The authors have studied duodenal blood flow during the development of an acute to chronic duodenal ulcer by using the abscopal model, in which ulcers are generated as an indirect effect of lower mediastinal irradiation. Female CFLP mice were randomly allocated to one of three groups. Irradiated ``controls`` received 18 Gy 250 kV X-rays to the upper mediastinum. The lower mediastinum group received the same dose of irradiation, which has been shown to induce typical chronic duodenal ulcers in 45% of animals so treated. Animals were studied by means of radiolabelled microspheres 3 or 7 days later. Proximal duodenal blood flow specifically was reduced by 32% in the lower mediastinum group compared with irradiated controls at 7 days. There was no significant difference in blood flow to the stomach and to the distal duodenum. The decrease in proximal duodenal blood flow in the lower mediastinum group did not differ in the five animals that developed ulcer compared with the seven that did not. Although, there is an overall decrease in duodenal blood flow associated with chronic duodenal ulcer, reduced blood flow may not explain individual susceptibility to ulceration. 21 refs., 1 fig., 2 tabs.

Chronic venous stasis is an extremely complex clinical syndrome of pain and changes in the skin that can involve the superficial, deep, and perforating veins. This syndrome is commonly referred to as the postphlebitic syndrome, implying that thrombophlebitis is its sole etiology. To test this hypothesis, the authors performed ascending venography on 51 limbs of patients with the chromic venous stasis syndrome and demonstrated that 32 had no radiological evidence of recent or old thrombophlebitis. Instead, they had normal-appearing veins, suggesting primary incompetence of the deep and/or perforating venous valves rather than thrombophlebitis as the etiology. Since various operations have recently been proposed to correct or bypass malfunctioning valves, precise demonstration of pathological change is required to choose the appropriate procedure and to evaluate results. Descending venograms were combined with the ascending studies in 42 limbs for this purpose. In addition to outlining the abnormalities responsible for chronic venous stasis syndrome in individual cases, interesting conclusions regarding the syndrome itself were reached

Full Text Available La úlcera de etiología venosa es la más prevalente de las úlceras de extremidad inferior. Entre el 75 y el 80% de las úlceras de la extremidad inferior son de esta etiología. De acuerdo con las evidencias disponibles, el tratamiento de las úlceras de etiología venosa tiene como base dos grandes pilares: el manejo de la úlcera como una herida crónica y el control de la hipertensión venosa crónica (HTV, su causa primordial, mediante sistemas de alta compresión decreciente y mantenida. 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.

Objective  To determine the effect of low dose aspirin on ulcer healing in patients with venous leg ulcers. Design  Pragmatic, community based, parallel group, double blind, randomised controlled trial. Setting  Five community nursing centres in New Zealand. Participants  251 adults with venous leg ulcers who could safely be treated with aspirin or placebo: 125 were randomised to aspirin and 126 to placebo. Interventions  150 mg oral aspirin daily or matching placebo for up to 24 weeks treatment, with compression therapy as standard background treatment. Main outcome measures  The primary outcome was time to complete healing of the reference ulcer (largest ulcer if more than one ulcer was present). Secondary outcomes included proportion of participants healed, change in ulcer area, change in health related quality of life, and adverse events. Analysis was by intention to treat. Results  The median number of days to healing of the reference ulcer was 77 in the aspirin group and 69 in the placebo group (hazard ratio 0.85, 95% confidence interval 0.64 to 1.13, P=0.25). The number of participants healed at the endpoint was 88 (70%) in the aspirin group and 101 (80%) in the placebo group (risk difference -9.8%, 95% confidence interval -20.4% to 0.9%, P=0.07). Estimated change in ulcer area was 4.1 cm 2 in the aspirin group and 4.8 cm 2 in the placebo group (mean difference -0.7 cm 2 , 95% confidence interval -1.9 to 0.5 cm 2 , P=0.25). 40 adverse events occurred among 29 participants in the aspirin group and 37 adverse events among 27 participants in the placebo group (incidence rate ratio 1.1, 95% confidence interval 0.7 to 1.7, P=0.71). Conclusion  Our findings do not support the use of low dose aspirin as adjuvant treatment for venous leg ulcers. Trial registration  ClinicalTrials.gov NCT02158806.

Is total abolishment of great saphenous reflux in the invasive treatment of superficial chronic venous insufficiency always necessary?

Science.gov (United States)

Navarro, T P; Nunes, T A; Ribeiro, A L; Castro-Silva, M

2009-02-01

Chronic venous insufficiency ranges from mild telangiectasias to skin ulceration with poor prognosis regarding healing and quality of life. Varicose veins are the most frequent clinical presentation, affecting 75% of such patients and 71% are due to primary reflux of great saphenous vein, which is the most compromised vein in chronic venous insufficiency. However, about 75% of these veins are not dilated. The standard treatment has been stripping of the saphenous vein, because it has 85% of good results at long term. However, saphenous vein is the main arterial substitute and should be spared whenever possible. The development of non-invasive diagnostic methods showed that hemodynamic worsening correlates with clinical severity and that the majority of patients did not have a dilated saphenous vein. Thus, several selective operations proposed to spare the saphenous vein have reported good results. Minimally invasive techniques (eco-guided foam, radiofrequency and laser) have also emerged aiming to obliterate the vein and abolishing reflux and have also reported good results, but they do not spare the vessel. Measurement of saphenous diameter has been shown to correlate with clinical and hemodynamic worsening, thus allowing planning the invasive treatment of chronic venous insufficiency. Dilated diameters (>7.2 mm) correlate with severe disease and poor prognosis, being an indication for total abolishment of saphenous vein reflux. All other presentations must be individualized, sparing saphenous vein whenever possible and and a standardized approach is not indicated for all patients.

Except for compression therapy, physical therapy has scarcely been evaluated in the treatment of chronic venous disorders (CVD). Spa treatment is a popular way to administer physical therapy for CVD in France, but its efficacy has not been evaluated yet. This study aimed to assess the efficacy of balneotherapy associated with patient education, as performed in the spa resort of La Léchère, in patients with advanced chronic venous insufficiency (CEAP clinical classes C4/C5). The study was a randomized controlled trial, spa therapy being administered on top of the usual medical care. Evaluation was by a blinded independent investigator. Subjects were patients with primary or post-thrombotic CVD with skin changes but no active ulcer (C4a, C4b, or C5), living in Grenoble area, and willing to undergo a spa treatment course in La Léchère. The treated group had the three week spa treatment course in La Léchère, soon after randomization; the control group also had a spa treatment, but starting at day 365. The treatment consisted of four balneology sessions per day, six days a week during three weeks, and three educational workshops. An independent follow-up was performed in Grenoble hospital every three months for 15 months. The main outcome criterion was the severity of the skin changes, as evaluated by means of malleolar chromametry. Quality of life, as measured by the Chronic Venous Insufficiency Questionnaire 2 scale, a visual analog scale (VAS) for leg symptoms, and the occurrence of leg ulcers were used as secondary criteria. The year after spa treatment in the treated group was compared with the year before spa treatment in the control group. Fifty-nine subjects were enrolled (29 in the treatment group and 30 in the control group). No statistically significant difference between groups was found at study onset regarding age, sex, etiology, CEAP "C" class, and the outcome variables. After treatment, chromametry showed significantly decreased pigmentation and

To determine the increase in healing rate of venous ulcer in patients receiving a micronised purified flavonoid fraction (MPFF) as supplementation to standard local care. A randomised, open, controlled, multicentre study. Departments of Dermatology and University Outpatients Clinics. One hundred and forty patients with chronic venous insufficiency and venous ulcers. PATIENTS received standard compressive therapy plus external treatment alone or 2 tablets of MPFF daily in addition to the above treatment for 24 weeks. Healing of ulcers and their reduction in size after 24 weeks of treatment. The percentage of patients whose ulcers healed completely was found to be markedly higher in those receiving MPFF in addition to standard external and compressive treatment than in those treated with conventional therapy alone (46.5% vs 27.5%; p<0.05. OR=2.3, 95% CI 1.1-4.6). Ulcers with diameters <3 cm were cured in 71% of patients in the MPFF group and in 50% of patients in the control group, whereas ulcers between 3 and 6 cm in diameter were cured in 60% and 32% of patients (p<0.05), respectively. The mean reduction in ulcer size was also found to be greater in patients treated with MPFF (80%) than in the control group (65%) (p<0.05). The cost-effectiveness ratio (cost per healed ulcer) in the MPFF group was 1026.2 compared with 1871.8 in the control group. These results indicate that MPFF significantly improves the cure rate in patients with chronic venous insufficiency.

The selection of topical and systemic therapies for the treatment of venous ulcers with signs of infection is challenging and should be accompanied by specific precautionary measures to protect against cross-contamination in the presence of multidrug-resistant microorganisms. However, there are still no clinical indicators for this situation, and confirmation of resistant strains occurs through culture and sensitivity, which can take up to 14 days. During this period, protective measures may no longer be taken, contributing to the spread of these pathogens. This study aimed to analyze the relationship between clinical signs and symptoms of infection in venous ulcers and the presence of antimicrobial-resistant Staphylococcus aureus and/or Pseudomonas spp. A cross-sectional study was developed including 69 patients with 98 venous ulcers. Clinical observation protocol was applied to detect infection indicators established by the European Wound Management Association and microbiological analysis of samples of the lesions. Fisher's exact test and χ 2 were used for analyses (P 70%): discoloration of the opaque type and/or dark brick red and increased exudate volume; 31 (31.6%) ulcer samples showed positive culture for the bacteria studied. There was no relationship between signs and symptoms of infection and the presence of multidrug-resistant microorganisms. Taking into account the percentage of lesions with resistant strains, for safe care, contact precautionary measures should be implemented in the treatment rooms, in addition to standard precautions.

The recent use of graduated compression therapy for treatment of chronic venous disorders such as leg ulcers and oedema has led to considerable research interest in flexible and low-cost force sensors. Properly applied low pressure during compression therapy can substantially improve the treatment of chronic venous disorders. However, achievement of the recommended low pressure levels and its accurate determination in real-life conditions is still a challenge. Several thin and flexible force sensors, which can also function as pressure sensors, are commercially available, but their real-life sensing performance has not been evaluated. Moreover, no researchers have reported information on sensor performance during static and dynamic loading within the realistic test conditions required for compression therapy. This research investigated the sensing performance of five low-cost commercial pressure sensors on a human-leg-like test apparatus and presents quantitative results on the accuracy and drift behaviour of these sensors in both static and dynamic conditions required for compression therapy. Extensive experimental work on this new human-leg-like test setup demonstrated its utility for evaluating the sensors. Results showed variation in static and dynamic sensing performance, including accuracy and drift characteristics. Only one commercially available pressure sensor was found to reliably deliver accuracy of 95% and above for all three test pressure points of 30, 50 and 70 mmHg.

To systematically review the published academic literature on the cost of chronic ulcers. A literature search was conducted in MEDLINE, EMBASE, HealthSTAR, Econlit and CINAHL up to 12 May 2016 to identify potential studies for review. Cost search terms were based on validated algorithms. Clinical search terms were based on recent Cochrane reviews of interventions for chronic ulcers. Titles and abstracts were screened by two reviewers to determine eligibility for full text review. Study characteristics were summarised. The quality of reporting was evaluated using a modified cost-of-illness checklist. Mean costs were adjusted and inflated to 2015 $US and presented for different durations and perspectives. Of 2267 studies identified, 36 were eligible and included in the systematic review. Most studies presented results from the health-care public payer or hospital perspective. Many studies included hospital costs in the analysis and only reported total costs without presenting condition-specific attributable costs. The mean cost of chronic ulcers ranged from $1000 per year for patient out of pocket costs to $30,000 per episode from the health-care public payer perspective. Mean one year cost from a health-care public payer perspective was $44,200 for diabetic foot ulcer (DFU), $15,400 for pressure ulcer (PU) and $11,000 for leg ulcer (LU). There was large variability in study methods, perspectives, cost components and jurisdictions, making interpretation of costs difficult. Nevertheless, it appears that the cost for the treatment of chronic ulcers is substantial and greater attention needs to be made for preventive measures.

Thermometric measurements were performed of 408 teeth of the upper and lower jaw with clinically confirmed initial and advanced stage of chronic ulcerous pulpitis in 398 subjects, aged from 18 to 30. Temperature elevation within the range from 1.4 to 3.2 degrees C was established in the initial form of chronic pulpitis and from 1 to 2.5 degrees C in advanced form of chronic pulpitis as compared with the norm. Significant difference in the temperature deviations exists in both forms of chronic pulpitis between the teeth of the upper and lower jaw.

'Chronic cerebrospinal venous insufficiency' in multiple sclerosis. Is multiple sclerosis a disease of the cerebrospinal venous outflow system?

International Nuclear Information System (INIS)

2011-01-01

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.

2018-05-01

To review the effect of dipeptidyl peptidase 4 (DPP-4) inhibitors on the wound healing and its mechanisms in chronic diabetic foot ulcers. The latest literature concerning DPP-4 inhibitors for chronic diabetic foot ulcers was extensively reviewed, as well as the potential benefit and mechanism of DPP-4 inhibitors on wound healing of diabetic foot ulcers was analyzed thoroughly. DPP-4 inhibitors can accelerated the ulcer healing. The mechanisms probably include inhibiting the expression of the matrix metalloproteinase (MMP) and restoring the balance of the wound MMP and the tissue inhibitors of MMP; promoting recruitment of endothelial progenitor cells and augmenting angiogenesis; optimizing extracellular matrix construction and the immune response to persistent hypoxia in chronic diabetes wounds, and so on. At present, clinical researches show that DPP-4 inhibitors may be considered as an adjuvant treatment for chronic diabetic foot ulcers. DPP-4 inhibitors show promise in the local wound healing of chronic diabetic foot ulcers. However, more strictly designed, adequately powered, long-term follow-up, and high-quality randomized control trials are needed to further verify their efficacy and safety for chronic diabetic foot ulcers.

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. 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. 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. 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 treatment of chronic, therapy-refractory ulcers. © 2017 The Author

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

Diabetes mellitus type 2 is one of the most common diseases with a prevalence increasing with age. If blood sugar is not controlled, complications arise and diabetic foot ulcer occurs. Depending on the blood vessels involved, we distinguish venous and arterial ulcers. Venous ulcers respond very well to modern methods of treatment such as compression therapy and hydrocolloid dressings, but for arterial ulcer prevention is most significant, e.g. weight loss, dietary modification, etc. The aim of this study was to show that despite all the available therapeutic options, we cannot cure ulcers completely because the patient's readiness to change his lifestyle plays a decisive role. Therefore, we present a patient having suffered from venous ulcers for several years and arterial ulcer that healed only after the patient had lost about 20 pounds.

Objective The aim of this study was to observe the change of the ankle joint range of motion, the muscle strength values measured with an isokinetic dynamometer, pain scores, quality of life scale, and venous return time in chronic venous insufficiency diagnosed patients by prospective follow-up after 12-week exercise program including isokinetic exercises. Methods The patient group of this study comprised 27 patients (23 female, 4 male) who were diagnosed with chronic venous insufficiency. An exercise program including isokinetic exercise for the calf muscle was given to patients three days per week for 12 weeks. At the end of 12 weeks, five of the patients left the study due to inadequate compliance with the exercise program. As a result, control data of 22 patients were included. Ankle joint range of active motion, isokinetic muscle strength, pain, quality of life, and photoplethysmography measurements were assessed before starting and after the exercise program. Results Evaluating changes of the starting and control data depending on time showed that all isokinetic muscle strength measurement parameters, range of motion, and overall quality of life values of patients improved. Venous return time values have also increased significantly ( p < 0.05). Conclusion In conclusion, increase in muscle strength has been provided with exercise therapy in patients with chronic venous insufficiency. It has been determined that the increase in muscle strength affected the venous pump and this ensured improvement in venous function and range of motion of the ankle. In addition, it has been detected that pain reduced and quality of life improved after the exercise program.

Full Text Available Recent reports have emerged suggesting that multiple sclerosis (MS may be due to abnormal venous outflow from the central nervous system, termed Chronic Cerebrospinal Venous Insufficiency (CCSVI. These reports have generated strong interest and controversy over the prospect of a treatable cause of this chronic debilitating disease. This review aims to describe the proposed association between CCSVI and MS, summarize the current data, and discuss the role of endovascular therapy and the need for rigorous randomized clinical trials to evaluate this association and treatment.

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.

Leg ulcers are a common condition. There have been very few studies of combined therapy involving VAC (vacuum-assisted closure) and skin graft. We performed a randomized controlled trial of VAC therapy vs. hydrocolloid dressings over 5 days following autologous grafting on chronic leg ulcers. The primary objective was to assess the difference in success (defined as a reduction in wound area of at least 50% at 1 month) between the two dressing methods. Forty-six patients with ulcers present for over one month were included. Following a 7-day hospitalization period, follow-up was performed for 3 months on an outpatient basis. Our study does not demonstrate a statistically significant difference, with a 45.8% success rate in the VAC group vs. 40.9% in the conventional dressing group (P=0.73). In the venous ulcer group, the success rate was 57.9% for VAC vs. 40% for conventional dressings (P=0.3). The difference in favor of VAC in this group was not statistically significant, most likely due to an insufficient number of patients studied. Our study does not demonstrate superiority of VAC associated with skin graft over conventional dressings. We observed more complications with VAC (40%) than with conventional dressings (23%) (P=0.06). Copyright © 2015 Elsevier Masson SAS. All rights reserved.

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

It is known that at least 90% of duodenal ulcers are caused by infection with the bacterium Helicobacter pylori. Eradicating this organism usually results in complete resolution of the disease (Rosengren, Br J Gen Pract 46(409):491-492, 1996). To study the different changes if any in stomach wall at sites other than the ulcer in chronic duodenal ulcer patients by upper Gastro-Intenstinal Endoscopy followed by histopathological examination of different parts of stomach. This study was a retrospective study conducted in the Department of General surgery, V.S.S. Medical College, Burla, Sambalpur, odisha during the period of June 2007 to May 2009. Subjects were patients with chronic duodenal ulcer who underwent endoscopic examination, gastric biopsy and rapid urease test. Chronic gastritis of antrum, followed by erythematous pangastritis was the prominent feature both in endoscopy and histopathological examination. The Inflammatory change affected the mucosa and submucosa of the stomach wall. The prevalence rate of Helicobacter pylori was 84%, the antrum being the most common affected part (84%) followed by gastric fundus (41%). Chronic superficial atrophic gastritis of antrum, followed by pangastritis is the most common pathological abnormality in stomach wall in CDU cases. Gastric antrum is the most common site for H. pylori colonization followed by fundus. Presence of H. pylori in stomach wall is associated with active on chronic gastritis.

Full Text Available Aim: The aim of the paper was to describe chosen aspects of quality of life in patients with venous leg ulcers treated at home in the Turiec region, and to find differences in assessing quality of life in relation to degree of adherence to external compression therapy. Design: A quantitative cross-sectional study. Methods: There were 61 patients with venous leg ulcers at 68.59 ± 9.49 years of age, with an average length of wound treatment of 6.34 ± 5.51 years. The adapted self-assessment questionnaire, the Freiburg Life Quality Assessment wound module (FLQA-w, was used to gain empirical data. Results: The findings revealed that the worst score was achieved in the category of everyday life (3.61 ± 0.93. Statistically significant differences were found between the group of respondents who apply bandages on a daily basis and those who did not use them at all. Regular bandage application is closely connected with positive assessment of wound therapy (p = 0.043, psychosocial life (p = 0.023, verbalisation of well-being in various categories (p = 0.001, assessment of state of the wound (p = 0.032, assessment of health condition (p = 0.019, and overall quality of life (p = 0.014. Length of wound treatment is related to assessments of quality of life. Conclusion: Non-healing wounds, the associated therapy and financial means required to treat them, and the pain resulting from them, are connected with physical difficulty, experience of negative emotions, and, thus, the worsening of patientsʼ quality of life. The results of the study could form the basis for further studies on similar issues.

To examine the internal and external responsiveness of the Pressure Ulcer Scale for Healing (PUSH) tool for assessing the healing progress in acute and chronic wounds. It is important to establish the responsiveness of instruments used in conducting wound care assessments to ensure that they are able to capture changes in wound healing accurately over time. Prospective longitudinal observational study. The key study instrument was the PUSH tool. Internal responsiveness was assessed using paired t-testing and effect size statistics. External responsiveness was assessed using multiple linear regression. All new patients with at least one eligible acute or chronic wound, enrolled in the Nurse and Allied Health Clinic-Wound Care programme between 1 December 2012 - 31 March 2013 were included for analysis (N = 541). Overall, the PUSH tool was able to detect statistically significant changes in wound healing between baseline and discharge. The effect size statistics were large. The internal responsiveness of the PUSH tool was confirmed in patients with a variety of different wound types including venous ulcers, pressure ulcers, neuropathic ulcers, burns and scalds, skin tears, surgical wounds and traumatic wounds. After controlling for age, gender and wound type, subjects in the 'wound improved but not healed' group had a smaller change in PUSH scores than those in the 'wound healed' group. Subjects in the 'wound static or worsened' group had the smallest change in PUSH scores. The external responsiveness was confirmed. The internal and external responsiveness of the PUSH tool confirmed that it can be used to track the healing progress of both acute and chronic wounds. © 2016 The Authors.

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.

Chronic venous disorders (CVDs) have been estimated to affect up to 20 million Americans. Despite this huge prevalence, the signs, symptoms, and treatment outcomes in patients 65 years of age and older are not well defined. Our goal was to determine the presentation and treatment outcomes in elderly patients compared with a cohort of patients younger than 65 years. From January 2015 to December 2016, we retrospectively reviewed prospectively collected data from 38,750 patients with CVD from the Center for Vein Restoration's electronic medical record (NextGen Healthcare Information Systems, Irvine, Calif). We divided patients into two groups; group A patients were younger than 65 years, and group B patients were 65 years of age or older. Medical and surgical history, presenting symptoms, treatment modalities, and revised Venous Clinical Severity Score before and after intervention were evaluated. A multivariate logistic regression analysis was performed to determine the predictive value of presenting and associated symptoms. Groups A and B were subdivided by Clinical, Etiology, Anatomy, and Pathophysiology class for subgroup analysis. Data were analyzed with GraphPad Prism (GraphPad Software Inc, La Jolla, Calif) or SAS version 9.4 statistical software package (SAS Institute, Cary, NC). There were 27,536 patients in group A and 11,214 in group B. Women constituted 78% of all patients. Group B demonstrated a higher incidence of chronic diseases compared with group A (P ≤ .003). As initial presenting symptoms, pain, heaviness, fatigue, and aching were more common in group A than in group B (61% vs 55%, 30% vs 27%, 27% vs 24%, and 17% vs 12%, respectively; P ≤ .001). Swelling, skin discoloration, and venous ulceration were more common in group B than in group A (29% vs 23%, 12% vs 6%, and 5% vs 2%; P ≤ .001). Ablations were more commonly performed in group B patients with C4 to C6 disease (P ≤ .004). The revised Venous Clinical Severity Scores before and 1

Skin ulcers due to venous stasis or diabetes are common among the elderly and are difficult to treat. Repeated applications of cell-based products have been reported to result in cure or improvement of leg ulcers of small size in a fraction of patients. To examine the effects of frozen human allogeneic epidermal cultures for the treatment of acute and chronic ulcers. We treated a series of 10 consecutive patients with leg ulcers of different etiology and duration with frozen human allogeneic epidermal cultures stored frozen and thawed for 5-10 minutes at room temperature before application. Three patients had ulcers with exposed Achilles or extensor tendon. The ulcers treated were as large as 160 cm2 in area and of up to 20-years' duration. After preliminary preparation of the wounds by debridement to remove necrotic tissue and application of silver sulfadiazine to control infection, thawed cultures were applied biweekly from 2 to 15 times depending on the size and complexity of the ulcer. All ulcers healed, including those with tendon exposure. After the first few applications, granulation tissue formed in the ulcer bed and on exposed tendons, and epidermal healing took place through proliferation and migration of cells from the margins of the wound. The time required for complete healing ranged from 1 to 31 weeks after the first application. The use of frozen human allogeneic epidermal cultures is a safe and effective treatment for venous or diabetic ulcers, even those with tendon exposure. It seems possible that any leg ulcer will be amenable to successful treatment by this method.

To assess feelings of powerlessness and hope for cure in patients with chronic venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). A clinical, analytical, descriptive study was conducted from April to September 2012 in a wound-care clinic in Brazil, on consecutive patients presenting withVLUs and DFUs. The Powerlessness AssessmentTool for Adult Patients (PAT) and the Herth Hope Index (HHI) were used.Total PAT scores range 12-60 and the higher the score, the stronger the feelings of powerlessness. The HHI ranges 12-48, with higher scores indicating higher levels of hope In total, 80 consecutive patients were recruited (40 VLU and 40 DFU). Mean PAT score was 53.3 +/- 9.6 (range 21-60) for DFU patients and 34.3 +/- 7.7 (range 21-60; p = 0.001) forVLU patients, suggesting these individuals had strong feelings of powerlessness. The mean HHI was 16.5 +/- 16.5 (range 12-40) for DFU patients and 27.5 +/- 27.5 (range 12-40; p = 0.001) for patients with VLUs, indicating low levels of hope. The results suggest that patients with DFUs had stronger feelings of powerlessness regarding their condition and less hope of recovery compared with patients with VLUs.

A Novel Stretch Sensor to Measure Venous Hemodynamics

Full Text Available Chronic venous insufficiency is a debilitating condition causing varicose veins and venous ulcers. The pathophysiology includes reflux and venous obstruction. The diagnosis is often made by clinical examination and confirmed by Venous Doppler studies. Plethysmography helps to quantitatively examine the reflux and diagnose the burden of deep venous pathology to better understand venous hemodynamics, which is not elicited by venous duplex examination alone. However, most of these tests are qualitative, expensive, and not easily available. In this paper, we demonstrate the potential use of a novel stretch sensor in the assessment of venous hemodynamics during different maneuvers by measuring the change in calf circumference. We designed the stretch sensor by using semiconductor strain gauges pasted onto a small metal bar to form a load cell. The elastic and Velcro material attached to the load cell form a belt. It converts the change in limb circumference to a proportional tension (force of distension when placed around the calf muscle. We recorded the change in limb circumference from arrays of stretch sensors by using an in-house data acquisition system. We calculated the venous volume (VV, venous filling index (VFI, ejection fraction (EF and residual venous volume (RVV on two normal subjects and on two patients to assess venous hemodynamics. The values (VV > 60 ml, VFI 60%, RVV 2ml/s, EF 35% in patients were comparable to those reported in the literature.

Full Text Available Background : Chronic wounds, especially non-healing types, are one of the most common surgical conditions a surgeon comes across. The peculiarity of a chronic wound is that, whatever management you give, they refuse to heal, especially the pressure ulcers or bed sores. Many therapeutic methods are available to effect wound healing such as topical application of insulin, growth factors, negative pressure-assisted wound closure, oxidized regenerated cellulose/collagen, hyaluronic acid conjugated with glycidyl methacrylate or gelatin dressings. A less clinically and economically complicated approach to healing chronic wounds seems necessary. Objectives: To study the efficacy of topical use of insulin in wound healing in following terms:-(1 rate of wound healing; (2 safety evaluation; (3 hospital stay. Materials and Methods: This was a prospective study carried out in a tertiary health centre from July 2010 to September 2012 in 50 patients after taking an informed and written consent of the patients having chronic ulcer. All the patients who were satisfying inclusion/exclusion criteria patient were randomized into two groups, Group A and Group B. Each group was again sub-divided into 1 and 2 i.e. sub-group A1, A2 and sub-group B1, B2. Patients with diabetes were grouped as A1 and B1 and non-diabetic patients were grouped as A2 and B2. Group A patients were treated with insulin dressings and Group B patient′s ulcers were treated with normal saline dressings. Ulcer size and healing was recorded on weekly basis. Strict glycemic control was maintained in all diabetic patients. Results were compared at complete healing or at the end of 12 weeks which ever was earlier. Results: Our study included both diabetic and non-diabetic patients. There was no significant change in BSL(R values after use of insulin on wounds. The number of days required for wound healing in Group A patients in both subgroups (A1 and A2 was significantly less as compared to Group B

The authors present their experiences with endoscopic dissection of perforating veins in patients with severe forms of chronic venous insufficiency with special reference to the peculiarities of blood supply of the extremity superficial tissue. The generalized morphological description of the perforating arteriovenous structures of the leg is presented as a vascular formation including the arteries and veins put in the general connective-tissue vagina and beginning from the profound or/and muscular veins and arteries. Operations were made on 56 patients aged 25-76 years, 40 of them had postthrombotic disease, 16 - varicose disease. The endoscopic subfascial dissection of the perforating veins was conducted using the standard set of tools for laparoscopic surgery of K. Storz Company. During the surgical procedure the perforating vascular bunch in the subfascial space was isolated, the veins were intersected electrosurgically, the other parts of the vascular bunch were preserved. On the average, the patients were in the hospital for 7+/-2 days. Trophic ulcers healed up during 7-30 days. Long-term results were good in 30%, satisfactory in 64%, unsatisfactory - in 6%. So, the selective endoscopical dissection of perforating veins is thought to be a radical, minimally invasive, anatomically and functionally reasonable method of elimination of the horizontal venous blood regurgitation. This technique resulted in a considerably decreased number of postoperative complications and less time of hospital treatment.

Objective: To investigate the expression of the catalytic subunit of telomerase, telomerase reverse transcriptase (TRT) and the possible relationship between the TRT and cancer transformation or poor healing in radiation-induced chronic ulcer of human skin. Methods: Rabbit antibody against human TRT and SP immunohistochemical method were used to detect TRT expression in 24 cases of formalin-fixed, paraffin-embed human skin chronic ulcer tissues induced by radiation, 5 cases of normal skin, 2 of burned skin, and 8 of carcinoma. Results: The positive rate for TRT was 58.3%(14/24) in chronic radiation ulcers, of which the strongly positive rate was 41.7%(10/24) and the weakly positive 16.7%(4/24), 0% in normal (0/5) and burned skin (0/2), and 100% in carcinoma (8/8). The strongly positive expression of TRT was observed almost always in the cytoplasm and nucleus of squamous epithelial cells of proliferative epidermis but the negative and partly weakly positive expression in the smooth muscles, endothelia of small blood vessels and capillaries, and fibroblasts. Chronic inflammtory cells, plasmacytes and lymphocytes also showed weakly positive for TRT. Conclusion: TRT expression could be involved in the malignant transformation of chronic radiation ulcer into squamous carcinoma, and in the poor healing caused by sclerosis of small blood vessels and lack of granulation tissue consisting of capillaries and fibroblasts

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.

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

Deep venous thrombosis (DVT) is a well-known complication of an acute spinal cord injury (SCI). However, the prevalence of DVT in patients with chronic SCI has only been reported in a limited number of studies. The aim of our study was to examine the prevalence of DVT in patients with SCI beyond three months after injury. Cross-sectional study. Rehabilitation Department at the Bydgoszcz University Hospital in Poland. Sixty-three patients with SCI that were more than 3 months post injury. The patients, ranging in age from 13 to 65 years, consisted of 15 women and 48 men; the mean age of the patients was 32.1 years. The time from injury varied from 4 to 124 months. Clinical assessment, D-dimer and venous duplex scan. The venous duplex scan revealed DVT in 5 of the 63 patients. The post-injury time in four of the patients varied between 4 and 5 months; one patient was 42 months post-injury. DVT occurred in patients with chronic SCI, mainly by the 6th post injury month.

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.

The objective of the study was to evaluate the association of sociodemographic factors with hope for cure and levels of religiosity and spirituality in patients with venous leg ulcers (VLUs). This was a primary, prospective, descriptive, analytical, clinical, nonrandomized study. The study was performed at a nursing care and education center of a university hospital in interior Minas Gerais, Brazil. A convenience sample of 50 adult patients with VLUs and Doppler ankle-brachial index ranging from 0.8 to 1.0 participated in the study. Patients with mixed ulcers, arterial ulcers, and diabetic foot ulcers were excluded from the study. A questionnaire assessing sociodemographic and clinical characteristics of patients, the Spirituality Self-rating Scale (SSRS), and the Herth Hope Index (HHI) were administered to all patients. The mean SSRS score was 10.20, and the mean HHI was 25.5, corresponding to low levels of spirituality and moderate hope for cure, respectively. Patients aged between 50 and 59 years, men, nonsmokers, and those who were unemployed had the lowest mean SSRS scores. The lowest mean HHI values were reported by patients whose ulcers had exudate and odor, those aged 20 to 39 years, retired, and living with the wound for 1 year or less. Patients who had no religion or were not practicing a religion and those who considered living with an ulcer as a punishment reported low SSRS scores. The results showed that most patients with VLUs had low levels of spirituality, did not perceive divine intervention in their daily life or practice religious activities such as prayer, and had moderate hope for cure.

To clarify the frequency and severity of diabetic retinopathy in a group of people with Type 2 diabetes and chronic diabetic foot ulcers, and to compare visual acuity, levels of retinopathy and clinical significant macular oedema with a matched control group of people with Type 2 diabetes without a history of chronic diabetic foot ulcers. Visual acuity and fundus imaging were evaluated in 90 white people with at least 3 months' duration of full-thickness diabetic foot ulcers below the ankle and the results compared with those in 180 white people with Type 2 diabetes without a history of chronic diabetic foot ulcers (control group). Controls were matched for age, sex and duration of diabetes. Despite similar age and diabetes duration, severe non-proliferative or proliferative diabetic retinopathy was present in 41% of the people in the diabetic foot ulcer group as compared to 15% in the control group (Pdiabetic foot ulcer group was without any diabetic retinopathy as compared to 34% among controls. Proliferative diabetic retinopathy was more common in the diabetic foot ulcer group (31% vs 8%; Pdiabetic retinopathy did not differ between groups. Clinically significant macular oedema was more frequently present, and the diabetic foot ulcer group exhibited significantly worse results in best and worst eye visual acuity testing. In this northern European setting almost all people with Type 2 diabetes and chronic diabetic foot ulcers had diabetic retinopathy. Almost one-third had proliferative diabetic retinopathy as compared to diabetic retinopathy was linked to worse visual acuity. This article is protected by copyright. All rights reserved.

Bleeding is a serious and frequent complication of peptic ulcer disease. Hepatic dysfunction can cause coagulopathy and increases the risk of peptic ulcer bleeding. However, whether chronic liver disease increases mortality after peptic ulcer bleeding remains unclear. To examine the prognostic impact of chronic liver disease on mortality after peptic ulcer bleeding. We used population-based medical registries to conduct a cohort study of all Danish residents hospitalised with incident peptic ulcer bleeding from 2004 through 2011. We identified patients diagnosed with liver cirrhosis or non-cirrhotic chronic liver disease before their admission for peptic ulcer bleeding. We then computed 90-day mortality after peptic ulcer bleeding based on the Kaplan-Meier method (1 - survival function) and used a Cox regression model to estimate mortality rate ratios (MRRs), controlling for potential confounders. We identified 21,359 patients hospitalised with peptic ulcer bleeding. Among these, 653 (3.1%) had a previous diagnosis of liver cirrhosis and 474 (2.2%) had a history of non-cirrhotic chronic liver disease. Patients with liver cirrhosis and non-cirrhotic chronic liver disease had a cumulative 90-day mortality of 25.3% and 20.7%, respectively, compared to 18.3% among patients without chronic liver disease. Liver cirrhosis was associated with an adjusted 90-day MRR of 2.38 (95% CI: 2.02-2.80), compared to 1.49 (95% CI: 1.22-1.83) among patients with non-cirrhotic chronic liver disease. Patients with chronic liver disease, particularly liver cirrhosis, are at increased risk of death within 90 days after hospitalisation for peptic ulcer bleeding compared to patients without chronic liver disease. © 2015 John Wiley & Sons Ltd.

Venous thromboembolic events result in significant morbidity, mortality, and costly therapeutic interventions. As medical resource allocation strategies are becoming more pervasive, appropriate risk stratification and prophylactic regimens are essential. Previous studies have shown a decreased incidence of perioperative venous thromboembolism in the chronic spinal cord injury population. The question remains of whether chronic spinal cord injury is protective against venous thromboembolism. A retrospective review of all cases involving chronic spinal cord injury patients who underwent plastic and reconstructive surgery operations (n = 424) and general surgery patients (n = 777) with a primary outcome of deep venous thrombosis or pulmonary embolism within 90 days of surgery was performed. The incidence of postoperative deep venous thrombosis in the control and spinal cord injury groups was 1.7 percent and 0.2 percent, respectively (p = 0.027). However, such significance was not observed with regard to postoperative pulmonary embolism incidence (p = 0.070). Collectively, the incidence of postoperative venous thromboembolism-specifically, deep venous thrombosis or pulmonary embolism-was significantly greater in the general surgery population (p = 0.014). A nearly 10-fold increased risk of venous thromboembolism was seen among the control group (1.9 percent versus 0.2 percent) despite administration of optimal prophylaxis. This study demonstrates a profoundly low incidence of venous thromboembolism among chronic spinal cord injury patients compared with general surgery patients. Future efforts to elucidate how chronic spinal cord injury confers a protective mechanism may potentially influence the evolution of venous thromboembolism prevention guidelines, and spark the development of alternative prophylactic agents or customized application of prevention efforts.

The study aimed to evaluate the ratio of venous contamination in diabetic cases without foot lesion, with foot lesion and with Charcot neuroarthropathy (CN). Bolus-chase three-dimensional magnetic resonance (MR) of 396 extremities of patients with diabetes mellitus was analyzed, retrospectively. Extremities were divided into three groups as follows: diabetic patients without foot ulcer or Charcot arthropathy (Group A), patients with diabetic foot ulcers (Group B) and patients with CN accompanying diabetic foot ulcers (Group C). Furthermore, amount of venous contamination classified as no venous contamination, mild venous contamination, and severe venous contamination. The relationship between venous contamination and extremity groups was investigated. Severe venous contamination was seen in Group A, Group B, and Group C, 5.6%, 15.2%, and 34.1%, respectively. Statistically significant difference was seen between groups with regard to venous contamination. Venous contamination following bolus chase MR was higher in patients with CN.

Full Text Available Only 30 percent of chronic diabetic foot ulcers heal after 20 weeks of standard treatment. Pirfenidone is a drug with biological, anti-inflammatory, and antifibrotic effects. The aim of this study was to evaluate the effect of topical pirfenidone added to conventional treatment in noninfected chronic diabetic foot ulcers. This was a randomized crossover study. Group 1 received topical pirfenidone plus conventional treatment for 8 weeks; after this period, they were switched to receive conventional treatment only for 8 more weeks. In group 2, the order of the treatments was the opposite. The end points were complete ulcer healing and size reduction. Final data were obtained from 35 ulcers in 24 patients. Fifty-two percent of ulcers treated with pirfenidone healed before 8 weeks versus 14.3% treated with conventional treatment only (P=0.025. Between 8 and 16 weeks, 30.8% ulcers that received pirfenidone healed versus 0% with conventional treatment (P=0.081. By week 8, the reduction in ulcer size was 100% [73–100] with pirfenidone versus 57.5% with conventional treatment [28.9–74] (P=0.011. By week 16, the reduction was 93% [42.7–100] with pirfenidone and 21.8% [8–77.5] with conventional treatment (P=0.050. The addition of topical pirfenidone to conventional treatment significantly improves the healing of chronic diabetic noninfected foot ulcers.

Endovascular Treatment Options in the Management of Lower Limb Deep Venous Thrombosis

International Nuclear Information System (INIS)

Nazir, Sarfraz Ahmed; Ganeshan, Arul; Nazir, Sheraz; Uberoi, Raman

2009-01-01

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.

This study aimed to systematically evaluate maggot debridement therapy (MDT) in the treatment of chronically infected wounds and ulcers. We performed a meta-analysis referring to the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). We searched for published articles in the following databases: PubMed, Web of Science, Embase, Wanfang (Chinese), and the China National Knowledge Infrastructure (CNKI). The latest search was updated on March 14, 2014. For dichotomous outcomes, the effects of MDT were expressed as the relative risk (RR) and 95% confidence interval (CI). For continuous outcomes with different measurement scales, we calculated the standardized mean difference (SMD). The pooled effects were estimated using a fixed effect model or random effect model based on the heterogeneity test. Subgroup analyses were performed according to the types of wounds or ulcers. MDT had a significantly increased positive effect on wound healing compared with conventional therapies, with a pooled RR of 1.80 (95% CI 1.24-2.60). The subgroup analysis revealed that the combined RRs were 1.79 (95% CI 0.95-3.38) for patients with diabetic foot ulcers (DFU) and 1.70 (95% CI 1.28-2.27) for patients with other types of ulcers. The time to healing of the ulcers was significantly shorter among patients treated with MDT, with a pooled SMD of -0.95 (95% CI -1.24, -0.65). For patients with DFU, the SMD was -0.79 (95% CI -1.18, -0.41), and for patients with other types of ulcers, the SMD was -1.16 (95% CI -1.63, -0.69). MDT not only shortened the healing time but also improved the healing rate of chronic ulcers. Therefore, MDT may be a feasible alternative in the treatment of chronic ulcers.

Adjuvant Biological Therapies in Chronic Leg Ulcers

Directory of Open Access Journals (Sweden)

Natalia Burgos-Alonso

2017-11-01

Full Text Available Current biological treatments for non-healing wounds aim to address the common deviations in healing mechanisms, mainly inflammation, inadequate angiogenesis and reduced synthesis of extracellular matrix. In this context, regenerative medicine strategies, i.e., platelet rich plasmas and mesenchymal stromal cell products, may form part of adjuvant interventions in an integral patient management. We synthesized the clinical experience on ulcer management using these two categories of biological adjuvants. The results of ten controlled trials that are included in this systematic review favor the use of mesenchymal stromal cell based-adjuvants for impaired wound healing, but the number and quality of studies is moderate-low and are complicated by the diversity of biological products. Regarding platelet-derived products, 18 controlled studies investigated their efficacy in chronic wounds in the lower limb, but the heterogeneity of products and protocols hinders clinically meaningful quantitative synthesis. Most patients were diabetic, emphasizing an unmet medical need in this condition. Overall, there is not sufficient evidence to inform routine care, and further clinical research is necessary to realize the full potential of adjuvant regenerative medicine strategies in the management of chronic leg ulcers.

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.

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 ulceration associated with gout tophi is very difficult to treat because of impaired and halted local inflammatory response resulting from the gout treatment regimen. We report chronic nonhealing tophaceous gout with bursitis in an 80-year-old male, not responding to conventional treatment modality for months together. This nonhealing ulcer was treated successfully with local application of 3% citric acid ointment for 22 days.

Bidirectional crosstalk between stress-induced gastric ulcer and depression under chronic stress.

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.

Venous leg ulcers (VLU) have a huge social and economic impact. An estimated 1.5% of European adults will suffer a venous ulcer at some point in their lives. Despite the widespread use of bandaging with high pressure in the treatment of this condition, recurrence rates range between 25% to 70%. Numerous studies have suggested that the compression system should provide sub-bandage pressure values in the range from 35 mm Hg to 45 mm Hg in order to achieve the best possible healing results. An open, randomized, prospective, single-center study was performed in order to determine the healing rates of VLU when treated with different compression systems and different sub-bandage pressure values. One hundred thirty-one patients (72 women, 59 men; mean age, 59-years-old) with VLU (ulcer surface >3 cm(2); duration >3 months) were randomized into three groups: group A - 42 patients who were treated using an open-toed, elastic, class III compression device knitted in tubular form (Tubulcus, Laboratoires Innothera, Arcueil, France); group B - 46 patients treated with the multi-component bandaging system comprised of Tubulcus and one elastic bandage (15 cm wide and 5 cm long with 200% stretch, Niva, Novi Sad, Serbia); and group C - forty-three patients treated with the multi-component bandaging system comprised of Tubulcus and two elastic bandages. Pressure measurements were taken with the Kikuhime device (TT MediTrade, Soro, Denmark) at the B1 measuring point in the supine, sitting, and standing positions under the three different compression systems. The median resting values in the supine and standing positions in examined study groups were as follows: group A - 36.2 mm Hg and 43.9 mm Hg; group B - 53.9 mm Hg and 68.2 mm Hg; group C - 74.0 mm Hg and 87.4 mm Hg. The healing rate during the 26-week treatment period was 25% (13/42) in group A, 67.4% (31/46) in group B, and 74.4% (32/43) in group C. The success of compression treatment in group A was strongly associated with the

Glomerulonephritis is a rare complication in patients with inflammatory bowel disease. We report a case of membranous nephropathy (MN) in a 12.6-year-old girl with chronic ulcerative colitis. The girl was referred to the hospital with bloody diarrhea and arthralgia. Routine urinalysis showed 1 g/m(2) protein excretion in 24 h. Serum ANCA titers were positive. The diagnoses were confirmed by coloscopy and kidney biopsy. The patient's mother had also suffered from ulcerative colitis in adolescence. Proteinuria normalized under treatment with prednisone (60 mg/m(2)/day) and azathioprine, which was initiated to treat the colitis. Chronic ulcerative colitis can be associated with glomerulonephritis.

Massive (≥100 cm(2)) venous leg ulcers (VLUs) demonstrate very low closure rates with standard compression therapy and are costly to manage. Negative-pressure wound therapy (NPWT), followed by a split-thickness skin graft (STSG), can be a cost-effective alternative to this standard care. We performed a cost analysis of these two treatments. A retrospective review was performed of 10 ulcers treated with surgical debridement, 7 days of inpatient NPWT with topical antiseptic instillation (NPWTi), and STSG, with 4 additional days of inpatient NPWT bolster over the graft. Independent medical cost estimators were used to compare the cost of this treatment protocol with standard outpatient compression therapy. The average length of time ulcers were present before patients entered the study was 38 months (range, 3-120 months). Eight of 10 patients had complete VLU closure by 6 months after NPWTi with STSG. The 6-month costs of the proposed treatment protocol and standard twice-weekly compression therapy were estimated to be $27,000 and $28,000, respectively. NPWTi with STSG treatment is more effective for closure of massive VLUs at 6 months than that reported for standard compression therapy. Further, the cost of the proposed treatment protocol is comparable with standard compression therapy. Copyright © 2015 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

Three patients with chronic radiation ulcer treated with free musculocutaneous flap transfer are described. The first patient was a 66-year-old woman who developed sacral ulcer 7 years after radiation combined with surgery for uterine cancer. After debridement of this ulcer, interpositional vein grafts 30 cm in length was used to reconstruct an 'extended' latissimus dorsi musculocutaneous flap. The second patient was a 62-year-old woman. She developed ulcer on her chest 15 years after postoperative irradiation for breast cancer. Radiation damage extended to the myocardium and pulmonary parenchyma. After careful debridement, reconstruction was performed by using the free rectus abdominis musculocutaneous flap. The last patient was a 72-year-old woman. Ulcer of the right axilla developed 19 years after postoperative irradiation for breast cancer. Reconstruction was performed by using a free rectus abdominis musculocutaneous flap. In these patients in whom radiation-damaged tissue was not completely excised, favorable results could be attained by using the transfer of the free musculocutaneous flaps. (N.K.)

Venous leg ulcers produce significant clinical and economic burdens on society and often require advanced wound therapy. The purpose of this multicenter, randomized, controlled study is to evaluate the safety and efficacy of one or two applications of dehydrated human amnion/chorion membrane allograft and multilayer compression therapy vs. multilayer compression therapy alone in the treatment of venous leg ulcers. The primary study outcome was the proportion of patients achieving 40% wound closure at 4 weeks. Of the 84 participants enrolled, 53 were randomized to receive allograft and 31 were randomized to the control group of multilayer compression therapy alone. At 4 weeks, 62% in the allograft group and 32% in the control group showed a greater than 40% wound closure (p = 0.005), thus showing a significant difference between the allograft-treated groups and the multilayer compression therapy alone group at the 4-week surrogate endpoint. After 4 weeks, wounds treated with allograft had reduced in size a mean of 48.1% compared with 19.0% for controls. Venous leg ulcers treated with allograft had a significant improvement in healing at 4 weeks compared with multilayer compression therapy alone. © 2014 by the Wound Healing Society.

Chronic occlusions of the inferior vena cava (IVC) and iliofemoral veins are long-term sequelae of deep venous thrombosis (DVT) that can lead to postthrombotic syndrome (PTS). Patients may present with a wide spectrum of signs and symptoms, ranging from mild discomfort and swelling to severe venous hypertension and ulcerations. We report a 68-year-old man who had a history of left lower extremity DVT after a laminectomy and who developed PTS with nonhealing ulcers. The patient underwent a cross-pubic femorofemoral venous bypass that failed to improve his clinical status. After unsuccessful endovascular attempts for recanalization of the iliofemoral segment, a profunda femoris to IVC bypass was performed. The symptoms recurred 2 years later. Venography revealed restenosis at the caval anastomosis that did not resolve by endovascular means. A surgical revision was performed, and given the quality of the IVC, a jump bypass was created to the left renal vein. The swelling improved and the ulcers healed completely. Twenty-eight months after the complex reconstructions, he remains ulcer-free with mild edema controlled with stockings. Venous reconstructions remain a viable option for patients with symptomatic and recalcitrant nonmalignant obstruction of the large veins. Copyright © 2013 Annals of Vascular Surgery Inc.

Chronic ulcerative colitis is being encountered with increasing frequency in developing countries. In Amman, Jordan, the records of 372 patients with chronic ulcerative colitis diagnosed between 1994 and 2001 were reviewed. Bloody diarrhoea and crampy abdominal pain were the most common presenting symptoms (84% of patients). The mean age at onset was 31.8 years. In two thirds of patients the diagnosis was made more than 1 year after the onset of symptoms. The pattern of the disease differed from that in industrialized countries in the mild course of the disease, the absence of skin manifestations, and the rarity of colorectal cancer in our patients. The mortality rate was 6%.

Identifying characteristic cutaneous findings is important in determining the appropriate management of certain venous diseases. The health care provider should be familiar with the classic description of patterns and distributions of skin manifestations, such as varicose veins, stasis dermatitis, palpable cord, petechiae, and telangiectasias. In addition to the gross appearance of the skin, a skin biopsy may help elucidate a diagnosis. General treatment and prevention of the underlying venous pathology is essential. Furthermore, specific management of skin findings should include therapy to ameliorate progression of disease and symptomatology when warranted.

A wound is damage of a tissue usually caused by laceration of a membrane, generally the skin. Wound healing is accomplished in three stages in healthy individuals, including inflammatory, proliferative, and remodeling stages. Healing of wounds normally starts from the inflammatory phase and ends up in the remodeling phase, but chronic wounds remain in an inflammatory stage and do not show progression due to some specific reasons. Chronic wounds are classified in different categories, such as diabetic foot ulcer (DFU), venous leg ulcers (VLU) and pressure ulcer (PU), surgical site infection (SSI), abscess, or trauma ulcers. Globally, the incidence rate of DFU is 1-4 % and prevalence rate is 5.3-10.5 %. However, colonization of pathogenic bacteria at the wound site is associated with wound chronicity. Most chronic wounds contain more than one bacterial species and produce a synergetic effect that results in previously non-virulent bacterial species becoming virulent and causing damage to the host. While investigating bacterial diversity in chronic wounds, Staphylococcus, Pseudomonas, Peptoniphilus, Enterobacter, Stenotrophomonas, Finegoldia, and Serratia were found most frequently in chronic wounds. Recently, it has been observed that bacteria in chronic wounds develop biofilms that contribute to a delay in healing. In a mature biofilm, bacteria grow slowly due to deficiency of nutrients that results in the resistance of bacteria to antibiotics. The present review reflects the reasons why acute wounds become chronic. Interesting findings include the bacterial load, which forms biofilms and shows high-level resistance toward antibiotics, which is a threat to human health in general and particularly to some patients who have acute wounds.

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.

The Salisbury Pressure Ulcer Outreach Service successfully treats patients with chronic pressure ulcers that have not healed during routine community treatment. These patients have grade 4 pressure ulcers, involving extensive destruction, or damage to muscle and bone. A combination of scientific, seating and tissue viability expertise with a holistic approach results in non-surgical healing for 70% of patients. For those who still require surgery, outcomes are more successful with this approach, resulting in low recurrence rates. Prior to creation of the outreach service, patients were referred directly for surgical closure, resulting in high recurrence levels and long waiting lists. The authors compared costs of the Pressure Ulcer Outreach Service with the previous system of surgical closure. The model base case found that the Pressure Ulcer Outreach Service saved £8588 per patient, and that cost savings could be even greater if the outreach service was extended into preventative work.

The brown pigmentation of the skin associated with venous ulceration is caused by increased local iron deposition. Diagnostic x-ray spectrometry, a method based on x-ray fluorescence analysis, was used for the noninvasive determination of iron levels in the skin of patients with venous ulceration. The mean (+/- SEM) iron concentration in the skin around the venous ulcer was elevated, compared with control values of nonulcerated skin (250 +/- 54 vs 128 +/- 39 micrograms) and compared with normal skin from the forearm (250 +/- 54 vs 14 +/- 2.5 micrograms). These data suggest that dermal iron deposition may not be an incidental by-product of increased venous pressure, but may actively perpetuate tissue damage in venous ulcerations

The controversy on chronic cerebrospinal venous insufficiency

Paolo Zamboni

2013-08-01

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

According to the National Institutes of Health classification of chronic graft-versus-host disease (cGVHD), skin ulcers after allogeneic haematopoietic stem-cell transplantation (HSCT) are recorded as having the maximal severity score but published data are scarce. To describe skin ulcers related to cGVHD with an emphasis on clinical findings, associated morbidity, management and evolution. A multicentre retrospective analysis was carried out of patients with a diagnosis of cGVHD skin ulcers. All 25 patients included in the study had sclerotic skin cGVHD and 21 had lichenoid skin lesions associated with the sclerotic skin lesions. Thirteen patients had severe cGVHD without considering the skin, because of the involvement of an extracutaneous organ by cGVHD. The median time from HSCT to the onset of ulcers was 44 months. In addition to scleroderma, initial skin lesions at the site of ulcers were bullous erosive lichen in 21 patients and bullous erosive morphoea in four patients. Fifteen patients had an inaugural oedema. Ulcers were mostly bilateral with a predilection for the lower limbs. They were frequently colonized but few infections occurred. Four patients died during a median follow-up period of 55 months. Chronic graft-versus-host disease skin ulcers occur in patients with sclerodermatous skin cGVHD, are associated with severe cGVHD, often start with bullous lichenoid lesions or bullous morphoea and seem to cause more morbidity than mortality, given the low rate of mortality observed in our series of patients. © 2014 British Association of Dermatologists.

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

Directory of Open Access Journals (Sweden)

Jae-Heung Park

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.

Cancer complicating chronic ulcerative and scarifying mucocutaneous disorders

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

However, controversies remain if all individuals benefit equally from education. A retrospective analysis. The study included medical records of patients with venous ulcers (n = 351) treated between 2001 and 2011 at the Clinic for Chronic Wounds at Bydgoszcz Clinical Hospital. We compared two groups of patients, (1) with at least one episode of recurrent ulcer during the five-year observation period, and (2) without recurrences throughout the analysed period in terms of their theoretical skills and knowledge on compression therapy recorded at baseline and after one month. Very good self-assessment of a patient's compression therapy skills and weak assessment of these skills by a nurse proved significant risk factors for recurrence of the ulcers on univariate analysis. The significance of these variables as independent risk factors for recurrent ulcers has been also confirmed on multivariate analysis, which also took into account other clinical parameters. Building up proper compression therapy skills among the patients should be the key element of a properly construed nurse-based prophylactic program, as it is the most significant modifiable risk factor for recurrent ulcers. Although the development of compression skills is undeniably important, also other factors should be considered, e.g. surgical correction of superficial reflux. Instruction on compression therapy should be conducted by properly trained nursing personnel - the nurses should have received both content and psychological training. The compression therapy training should contain practical instruction with guided exercises and in-depth objective

The aim of this study was to investigate a possible relationship between obesity and decreased mobility of the talocrural joint and in turn chronic venous disease. One hundred obese patients recruited at Hospital Santa Casa de Maringa, Parana were enrolled by order of arrival at the hospital in a randomized quantitative cross-sectional study. Inclusion criteria were patients with a body mass index above 30 kg/m(2) and the exclusion criteria were infectious conditions that would interfere with the assessment. Patients were graded according to the clinical, etiological, anatomical and pathophysiological classification. Talocrural goniometry was performed to assess the degree of mobility of the legs. The Kolmogorov-Smirnov normality test, Kruskal-Wallis test, Dunn's Multiple comparison test and analysis of variance were used for statistical analysis tests with an alpha error of 5% being considered acceptable. The increase in body mass index is correlated to the reduction in joint mobility (Kruskal-Wallis test: p-value Kruskal-Wallis test: p-value <0.0001). Obesity is associated with deterioration in joint mobility and worsening of chronic venous disease. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The present study was designed to reveal the usefulness of acupuncture for chronic pelvic pain syndrome with intrapelvic venous congestion as evaluated by symptom scores, transrectal ultrasonography (TRUS) and magnetic resonance (MR) venography. Ten male patients suffering from non-inflammatory chronic pelvic pain syndrome (National Institutes of Health (NIH) category IIIB) with intrapelvic venous congestion were treated using acupuncture. Eight patients had previously received pharmacotherapy, which was unsuccessful. Acupuncture was performed using disposable stainless steel needles, which were inserted into the bilateral BL-33 points and rotated manually for 10 min. The treatment was repeated every week for 5 weeks without other therapeutic maneuvers. Results from TRUS and MR venography, as well as clinical symptoms based on the NIH chronic prostatitis symptom index (NIH-CPSI) and the international prostate symptom score (IPSS), were compared before and after the treatment. No side-effects were recognized throughout the treatment period. The average pain and quality of life (QOL) scores of the NIH-CPSI 1 week after the 5th acupuncture treatment decreased significantly (P<0.05 and P<0.01, respectively) compared with the baseline. The maximum width of the sonolucent zone 1 week after the 5th treatment also decreased significantly (P<0.01, compared with the baseline). Intrapelvic venous congestion demonstrated by MR venography was significantly improved in four patients. This study provided novel information concerning the therapeutic effects of acupuncture on non-inflammatory chronic pelvic pain syndrome. (author)

The purpose of this study was to determine the wound healing effects of Acapsil, a white, odorless powder based on micropore particle technology (MPPT) (Willingsford Ltd, Southampton, UK) by comparing it to Gentaxane (Gentaksan, Borshchagovsky CCP, Kyiv, Ukraine) (polydimethylsiloxane powder with gentamicin antibiotic) and Ioddicerin (Farmak, Kyiv, Ukraine) (iodine with dimethyl sulfoxide [DMSO]). The study included 266 patients with primarily trophic ulcers caused by pancreatic diabetes and venous insufficiency of the lower extremities, carbuncles, phlegmons, infected third- or fourth-degree heat burns, and infiltrations of postoperative wounds. The products were applied once daily to the wound until it was clean (ie, free from necrosis, pus, and fibrinogenous thickenings). The number of days (mean ± standard deviation) to a clean wound was 3.0 ± 0.9 for MPPT (n = 88) compared with 7.0 ± 1.2 and 8.0 ± 1.1 for Gentaxane (n = 90) and iodine/DMSO (n = 88), respectively. Thus, MPPT reduced the time to reach a clean wound by 57% and 62%, respectively. Products were used once daily until a clean wound was reached, which also reflects the number of applications. Days to onset of granulation for MPPT, Gentaxane, and iodine/DMSO were 4.5 ± 0.8, 9.2 ± 1.4, and 10.3 ± 1.5 days, respectively; and days to onset of epithelialization were 7.8 ± 1.1, 14.1 ± 1.9, and 16.4 ± 2.7 days, respectively. Subgroup analysis of patients with diabetic foot and venous leg ulcers found that each of these demonstrated the same pattern of healing as the overall study. The number of hospitalization days was 14.6 ± 5.6 for MPPT, 21.0 ± 10.7 for Gentaxane, and 24.0 ± 7.9 for iodine/DMSO. Compared with Gentaxane, patients receiving MPPT had a 31% reduction in hospitalization duration and a 39% reduction compared with iodine/DMSO. These findings demonstrate that MPPT represents a valuable new approach to wound care.

The healing process of chronic wounds is complex, and the complete pathogenesis is not known. Diagnosis is currently based on visual inspection, biopsies and collection of samples from the wound surface. This is often time consuming, expensive and to some extent subjective procedures. Hyperspectral imaging has been shown to be a promising modality for optical diagnostics. The main objective of this study was to identify a suitable technique for reproducible classification of hyperspectral data from a wound and the surrounding tissue. Two statistical classification methods have been tested and compared to the performance of a dermatologist. Hyperspectral images (400-1000 nm) were collected from patients with venous leg ulcers using a pushbroom-scanning camera (VNIR 1600, Norsk Elektro Optikk AS).Wounds were examined regularly over 4 - 6 weeks. The patients were evaluated by a dermatologist at every appointment. One patient has been selected for presentation in this paper (female, age 53 years). The oxygen saturation of the wound area was determined by wavelength ratio metrics. Spectral angle mapping (SAM) and k-means clustering were used for classification. Automatic extraction of endmember spectra was employed to minimize human interaction. A comparison of the methods shows that k-means clustering is the most stable method over time, and shows the best overlap with the dermatologist's assessment of the wound border. The results are assumed to be affected by the data preprocessing and chosen endmember extraction algorithm. Results indicate that it is possible to develop an automated method for reliable classification of wounds based on hyperspectral data.

Dipeptidyl Peptidase 4 Inhibition May Facilitate Healing of Chronic Foot Ulcers in Patients with Type 2 Diabetes

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.

Chronic wounds represent a significant burden to patients, health care professionals and the entire health care system. Regarding the healing process, wounds can be classified as acute or chronic wounds. A wound is considered chronic if healing does not occur within the expected period according to the wound etiology and localization. Chronic wounds can be classified as typical and atypical. The majority of wounds (95 percent) are typical ones, which include ischemic, neurotrophic and hypostatic ulcers and two separate entities: diabetic foot and decubital ulcers. Eighty percent of chronic wounds localized on lower leg are the result of chronic venous insufficiency, in 5-10 percent the cause is of arterial etiology, whereas the rest are mostly neuropathic ulcers. Chronic wounds significantly decrease the quality of life of patients by requiring continuous topical treatment, causing immobility and pain in a high percentage of patients. Chronic wounds affect elderly population. Chronic leg ulcers affect 0.6-3 percent of those aged over 60, increasing to over 5 percent of those aged over 80. Emergence of chronic wounds is a substantial socioeconomic problem as 1-2 percent of western population will suffer from it. This estimate is expected to rise due to the increasing proportion of elderly population along with the diabetic and obesity epidemic. It has been proved that chronic wounds account for the large proportion of costs in the health care system, even in rich societies. Socioeconomically, the management of chronic wounds reaches a total of 2-4 percent of the health budget in western countries. Treatment costs for some other diseases are not irrelevant, nor are the method and materials used for treating these wounds. Considering etiologic factors, a chronic wound demands a multidisciplinary approach with great efforts of health care professionals to treat it more efficiently, more simply and more painlessly for the patient, as well as more inexpensively for

Epidemiology and diagnostics of venous disease in Poland

Full Text Available Cardiovascular diseases are the leading cause of death in Poland. The percentage of people who die from cardiovascular disease is decreasing year by year, but adequate patient education and access to specialist physicians are still required. Chronic venous disease is one of the disorders of this system, whose probability of occurrence increases with age. Other risk factors include gender, type of occupation, obesity, eating habits and constipation, pregnancy, and genetic factor. The symptoms of the disease include: pain, lower limb edema, fatigue / leg pain, tingling, enlargement of the small blood vessels, enlargement and constriction of the subcutaneous veins, skin lesions, skin discolouration, itching of the skin of the legs, congestive dermatitis, ulcers. The degree of disease is determined using the CEAP scale. Prophylactic and early detection of disease results in shorter treatment times and reduced costs. Unfortunately, a large number of primary care physicians are skipping the physical examination of the lower limb, thus prolonging the diagnosis process and the patient being treated for a more advanced disease. Studies show that there is a difference in the incidence of chronic venous disease and the severity of the disease, depending on the province that has been affected. This may indicate the need to standardize nationwide training methods for doctors. The most common method of treatment is the combination of pharmacotherapy and compression therapy.

Objectives We aimed at determining peptic ulcer disease (PUD) incidence among chronic kidney disease (CKD) patients during 1998–2008, compared to patients without CKD, and at examining associations between CKD and PUD. Methods Data for 1998–2008 were extracted from the National Health Insurance Research Database in Taiwan. The annual PUD incidence (cases per thousand persons per year) was calculated separately for patients with and without CKD. Characteristics of patients with newly diagnosed PUD (n = 16322) were compared to those of a control group without PUD (n = 32644). The 2 groups were matched for age, sex, and index year. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Results Over the 10-year period, the PUD incidence was ∼10–12 times higher in CKD patients than in those without CKD. Its incidence in elderly CKD patients increased rapidly over time. For CKD patients, most PUD events (>95%) were managed during hospitalization. Peptic ulcer risk, adjusted for all potential confounders, was much higher in CKD patients undergoing hemodialysis (adjusted OR, 9.74; 95% CI, 7.11–13.31). Maintenance hemodialysis patients were 2 times more likely to have gastric ulcers than duodenal ulcers, while CKD patients not on dialysis had similar risks for both. There were no significant interactions between medications and CKD status on the peptic ulcer risk. Unlike CKD patients on nonsteroidal anti-inflammatory drugs and clopidogrel, those on aspirin did not have a higher peptic ulcer risk (adjusted OR, 0.88; 95% CI, 0.44–1.77). Conclusions CKD patients have a substantially increased PUD risk, and the majority of CKD patients with PUD require hospital management. Further, peptic ulcer risk is affected by hemodialysis therapy, patient status (inpatient vs. outpatient), and ulcerogenic medications. PMID:24498412

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.

Science.gov (United States)

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. Copyright © 2015 Elsevier Masson SAS.

Despite the fact that the frequency of hypolactasia and lactose intolerance is similar in both chronic idiopathic ulcerative colitis patients and the general population, the elimination of dairy products from the patient's diet is a habitual recommendation. Hypolactasia is common in Mexico, but its relation to chronic idiopathic ulcerative colitis has not been established. To evaluate lactose digestion and lactose intolerance in persons with chronic idiopathic ulcerative colitis. Thirty-nine patients with confirmed chronic idiopathic ulcerative colitis diagnosis were included in the study (mean: 31 years, range: 15 to 38). Twenty-two patients presented with rectosigmoid involvement and the remaining patients with pancolitis. No patient showed inflammatory activity according to the Truelove-Witts criteria and all consumed dairy products before diagnosis. A prospective, controlled, double-blind, cross-over study was designed. Patients randomly received 12.5 g of lactose or maltose in 250 cc water- each test 72 hours apart - and ydrogen was measured in exhaled air before disaccharide ingestion and then every 30 minutes for 3 hours. Digestion was considered deficient when there was an increase in hydrogen of at least 20 ppm. Symptom intensities were evaluated by Visual Analog Scales before, during, and after the hydrogen test. Differences between the groups were contrasted with the Mann-Whitney U and the Wilcoxon tests. Eighteen patients (46%) presented with deficient lactose digestion. No significant differences were found in the symptoms, extension, or progression of chronic idiopathic ulcerative colitis between patients that could digest and those that could not digest lactose. No patient had symptom exacerbation with the disaccharides used. Lactose digestion deficiency frequency is similar in subjects with chronic idiopathic ulcerative colitis and in healthy individuals in Mexico. We do not know whether higher doses could have some effect, but symptoms in patients

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

Directory of Open Access Journals (Sweden)

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

Non-healing ulcers are a major health problem worldwide and have great impact at personal, professional and social levels, with high cost in terms of human and material resources. Recalcitrant non-healing ulcers are inevitable and detrimental to the lower limb and are a major cause of non-traumatic lower limb amputations. Application of autologous Platelet Rich Plasma (PRP) has been a major breakthrough for the treatment of non-healing and diabetic foot ulcers, as it is an easy and cost-effective method, and provides the necessary growth factors that enhance tissue healing. PRP is a conglomeration of thrombocytes, cytokines and various growth factors which are secreted by α-granules of platelets that augment the rate of natural healing process with decrease in time. The purpose of this case series was to evaluate the safety and efficacy of autologous platelet rich plasma for the treatment of chronic non-healing ulcers on the lower extremity. Autologous PRP was prepared from whole blood utilizing a rapid, intraoperative point-of-care system that works on the principle of density gradient centrifugation. Twenty Four (24) patients with non-healing ulcers of different etiologies, who met the inclusion criteria, were treated with single dose of subcutaneous PRP injections along with topical application of PRP gel under compassionate use. The mean age of the treated patients was 62.5 ± 13.53 years and they were followed-up for a period of 24 weeks. All the patients showed signs of wound healing with reduction in wound size, and the mean time duration to ulcer healing was 8.2 weeks. Also, an average five fold increase in the platelet concentrate was observed in the final PRP product obtained using the rapid point-of-care device, and the average platelet dose administered to the patients was 70.10 × 10 8 . This case series has demonstrated the potential safety and efficacy of autologous platelet rich plasma for the treatment of chronic non-healing ulcers. NCT

Steps Toward Creating A Therapeutic Community for Inpatients Suffering from Chronic Ulcers: Lessons from Allada Buruli Ulcer Treatment Hospital in Benin.

Full Text Available 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.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.Interviews with patients revealed that most patients had very little information about the identity of their illness and the duration of their treatment.

This evaluation involves an innovative muscle pump-activating device (geko™) as an adjunctive therapy with best practices for non-healing venous leg ulcers (VLUs). Stimulating the common peroneal nerve (at the fibular head), the geko™ device creates a response that acts as foot and calf muscle pumps, increasing venous, arterial and microcirculatory flow. The aim was to evaluate and determine if the geko™ is effective in this population and if it should be added to the medical supply formulary. In all, 12 patients with 18 recalcitrant VLUs (defined as less than 30% reduction in wound size in 30 days with best practices) in two community settings in Ontario consented to the evaluation and were treated with the geko™ for up to 20 weeks. A total of 44% of wounds healed, and 39% decreased in size. One patient non-adherent with the geko™ and best practices had deterioration in his or her wounds. With the patients as their own control, the mean weekly healing rate with the geko™ was 9·35% (±SD 0·10) compared to 0·06% (±SD 0·10) prior to baseline, which was statistically significant (P devices in 7 of 12 (58%) patients. One patient stopped the device due to rash, while another had to take breaks from using the device. Subsequently, the manufacturer (FirstKind Ltd) has developed a new device and protocol specific to the requirements of wound therapy to minimise this response. This small case series demonstrated the highly significant effectiveness of the geko™ device in these hard-to-heal VLUs. Further evaluations to determine dose and patient selection criteria are underway. © 2017 The Authors. International Wound Journal published by Medicalhelplines.com Inc and John Wiley & Sons Ltd.

The aim of the present study was to evaluate the clinical therapeutic effect of the combined application of alginate and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on the healing of refractory chronic skin ulcers. A single center, three arm, randomized study was performed at Jinan Central Hospital (Jinan, Shandong, China). A total of 60 patients with refractory chronic skin ulcers, which persisted for >1 month, were enrolled and randomly assigned into one of the following three groups: alginate dressing/rhGM-CSF group (group A), rhGM-CSF only group (group B) and conventional (vaseline dressing) group (group C). The wound area rate was measured, granulation and color were observed and pain was evaluated. The data were summarized and statistical analysis was performed. The results demonstrated that group A exhibited a significantly faster wound healing rate and lower pain score compared with the other groups (PCSF for the treatment of refractory chronic skin ulcers demonstrated significant advantages. It promoted the growth of granulation tissue, accelerated re-epithelialization and also effectively reduced wound pain, and thus improved the quality of life for the patient. This suggests that the combined application of alginate and rhGM-CSF may be an effective therapeutic strategy for the clinical treatment of refractory chronic skin ulcers.

A transversal descriptive quantitative study, conducted with 50 people with Venous Ulcer (VU) at an University Hospital, that aimed to ascertain the level of psychosocial adaptation of the Roy Model of people with VU. The study was approved by the Ethics Committee. The data were collected with a structured form. After organizing the data, composed of changes in the lives of people with VU, we classified it according to Roy's psychosocial aspects. We found that in the self-concept mode, 36% felt dissatisfied with physical appearance, and 18% had negative feelings; in the role-function mode: change in the working role (52.0%), housework (34.0%), marital (6.0%), leisure, pain, social, educational and transportation restrictions (82.0%); interdependence mode: support in treatment (82.0%), discrimination (58.0%). The identification of the psychosocial aspects directs nursing actions to consider the whole of the person receiving care in its relations with the environment, thus promoting a better level of adaptation.

Full Text Available Lymphoedema is a progressive condition that can have a marked physical and psychological impact on affected patients and significantly reduce the quality of life. The ulcers on chronic lymphoedema patient, which often also makes it impossible for them to work. If left untreated, tends to progress or worsen. Ulcers in lymphoedema patients, therefore, represent not only a medical but also a psychological problem. The treatment is often regarded as being worse than it actually is. In our study of more than 25 years shows around 10% cases are due to chronic lymphodema. Ulcers of chronic lymphoedema are classified into four stages according to their presentation. Their management depends upon their stage of presentation. Patients with chronic lymphoedema and ulceration require a different approach to treatment. The specific issues associated with managing the patient with lymphoedematous ulceration include, limb shape distortion i.e., elephantiasis, care of the skin creases and folds, and swelling of the toes and fore foot. Stage I ulcers will heal with conservative treatment without any surgical intervention. Stage II ulcers needs debridement of the wound and split-thickness skin grafting. The most difficult to treat are the stage III and IV ulcers, due to associated skin changes and reduced vascularity. These cases need debulking along with excision of the ulcer. In order to prevent recurrence of the ulcer in all the four stages needs prolonged follow-up and limb care.

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.

Partsch, B; Partsch, H

2008-01-01

The aim of this study was to measure the interface pressure of a newly designed two-layer compression stocking (Mediven ulcer kit Medi QMBH, Bayreuth, Germany) in different body positions and to compare the values with those obtained with another two-layer product. Interface pressure was measured on the distal medial leg in 16 legs of volunteers, with the basic layer alone and with the whole stocking kit in the supine, sitting and standing position for both stocking systems. The literature concerning ulcer-healing rates is reviewed. Mediven ulcerkit produced statistically significant higher pressure values than the ulcer stocking with a median resting value of 35.5 mmHg in the supine and 42.5 mmHg in the standing position. The pressure while standing comes close to values exerted by bandages. The basic layer alone applies a pressure of 20.5 mmHg. Especially designed compression stockings exerting sufficient interface pressure may be indicated in patients with small ulcers of short duration.

1986-01-01

The effect of oral administration of synthetic human epidermal growth factor/urogastrone (EGF/URO) on healing of chronic duodenal ulcers induced by cysteamine in rats was investigated and compared with that of cimetidine, a H2-receptor antagonist. After 25 and 50 days of treatment, synthetic human...... EGF/URO significantly increased healing of chronic duodenal ulcers to the same extent as cimetidine. Combined treatment with synthetic human EGF/URO and cimetidine for 25 days was more effective than synthetic human EGF/URO given alone, whereas combined treatment for 50 days was significantly more...... human EGF/URO is a potent inhibitor of gastric acid secretion when administered intravenously, but had no effect on acid secretion when given intraduodenally, which suggests that the effect of synthetic human EGF/URO is a direct action on the duodenal mucosa. In conclusion, this study showed that oral...

Chronic Stress Facilitates the Development of Deep Venous Thrombosis

Directory of Open Access Journals (Sweden)

Tao Dong

2015-01-01

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.

To establish the prevalence of leg ulceration in the Irish Health Service Executive (HSE) mid-western region and to determine the level of assessment and treatment patients have been receiving in the local community. Before the introduction of a Doppler training programme, all public health and community health nurses working in the Irish HSE mid-western area were requested to complete an audit form on each patient being treated for leg ulceration during a predefined one-week period. This form recorded details on patient demographics, ulcer aetiology, assessment and treatment. Out of 97 nurses, 96 responded to this audit, giving a response rate of 98.9%. A total of 429 patients with 449 leg ulcers were identified. Mean age was 75.5 years (standard deviation 10.7). Overall prevalence was 0.12%, which increased to 1.2% in those aged 70 years and over. Women were almost twice as likely as men to be affected (ratio of 1.8:1). The main causes of ulceration were reported as venous incompetence accounting for 63.3% (284/449) and arterial insufficiency accounting for 8% (36/449) of all ulcers. Only 59.9% (269/449) of all ulcerated limbs had ABPI measurements performed. Of those reported as venous in origin, 71.8% (204/284) had ABPI measurements recorded. Evidence-based care was generally apparent in this group, with 47.5% (97/204) receiving high compression and 18.1% (37/204) receiving reduced compression. However, in venous leg ulcers where ABPIs were not recorded (n=80) care appeared haphazard and inappropriate. Our study has identified the benefit of ABPI Doppler assessment.This assessment could be done in local health centres by trained nurses who could provide more appropriate and timely care to patients, thereby improving outcomes and relieving pressure on acute hospital clinics.

In search of an optimal compression therapy for venous leg ulcers, a systematic review and meta-analysis was performed of randomized controlled trials (RCT) comparing compression systems based on stockings (MCS) with divers bandages. RCT were retrieved from six sources and reviewed independently. The primary endpoint, completion of healing within a defined time frame, and the secondary endpoints, time to healing, and pain were entered into a meta-analysis using the tools of the Cochrane Collaboration. Additional subjective endpoints were summarized. Eight RCT (published 1985-2008) fulfilled the predefined criteria. Data presentation was adequate and showed moderate heterogeneity. The studies included 692 patients (21-178/study, mean age 61 years, 56% women). Analyzed were 688 ulcerated legs, present for 1 week to 9 years, sizing 1 to 210 cm(2). The observation period ranged from 12 to 78 weeks. Patient and ulcer characteristics were evenly distributed in three studies, favored the stocking groups in four, and the bandage group in one. Data on the pressure exerted by stockings and bandages were reported in seven and two studies, amounting to 31-56 and 27-49 mm Hg, respectively. The proportion of ulcers healed was greater with stockings than with bandages (62.7% vs 46.6%; P bandages better than MCS. Pain was assessed in three studies (219 patients) revealing an important advantage of stockings (P bandages, has a positive impact on pain, and is easier to use.

Deep venous thrombosis and postthrombotic syndrome: invasive management.

Science.gov (United States)

Comerota, A J

2015-03-01

Invasive management of postthrombotic syndrome encompasses the two ends of the deep vein thrombosis spectrum, patients with acute iliofemoral deep vein thrombosis and those with chronic postthrombotic iliofemoral venous obstruction. Of all patients with acute deep vein thrombosis, those with involvement of the iliofemoral segments have the most severe chronic postthrombotic morbidity. Catheter-based techniques now permit percutaneous treatment to eliminate thrombus, restore patency, potentially maintain valvular function, and improve quality of life. Randomized trial data support an initial treatment strategy of thrombus removal. Failure to eliminate acute thrombus from the iliofemoral system leads to chronic postthrombotic obstruction of venous outflow. Debilitating chronic postthrombotic symptoms of the long-standing obstruction of venous outflow can be reduced by restoring unobstructed venous drainage from the profunda femoris vein to the vena cava. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

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.

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. 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. 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 ulcers plays a facilitating role in healing due to the mechanism of laser-activated endogenous heat shock protection in cells in wound surfaces.

This is the fi rst prospective study done locally to determine the effectiveness of vacuum-assisted closure (VAC) therapy in the healing of chronic diabetic foot ulcers. An electronic vacuum pump was used to apply controlled negative pressure evenly across the wound surface. Changes in wound dimension, presence of wound granulation and infection status of diabetic foot ulcers in 11 consecutive patients with diabetes were followed over the course of VAC therapy. Healing was achieved in all wounds. Nine wounds were closed by split-skin grafting and 2 by secondary closure. The average length of treatment with VAC therapy was 23.3 days. Ten wounds showed reduction in wound size. All wounds were satisfactorily granulated and cleared of bacterial infection at the end of VAC therapy. VAC therapy was useful in the treatment of diabetic foot infection and ulcers, which after debridement, may present with exposed tendon, fascia and/or bone. These included ray amputation wounds, wounds post-debridement for necrotising fasciitis, wounds post-drainage for abscess, a heel ulcer and a sole ulcer. It was able to prepare ulcers well for closure via split-skin grafting or secondary closure in good time. This reduced cost of VAC therapy, as therapy was not prolonged to attain greater reduction in wound area. VAC therapy also provides a sterile, more controlled resting environment to large, exudating wound surfaces. Large diabetic foot ulcers were thus made more manageable.

Chronic cheek ulcer caused by odontogenic cutaneous sinus tract

Directory of Open Access Journals (Sweden)

Tomoya Sato

2015-06-01

Odontogenic cutaneous sinus tracts are often misdiagnosed, and they lead to facial wounds and scarring. Therefore, we must be aware of the possibility of this condition. A dental origin must be considered for chronic ulcers involving the cheek, chin and submental areas. The clinical course of this patient suggests two important clinical issues for prompt diagnosis. First, physical examination, including palpation and probing, are helpful for exploration of sinus tracts. Second, computed tomography is useful to detect the sinus tract and affected teeth. Computed tomography provides radiographic evidence of the relationship between the tooth and cutaneous region, and it may be superior to radiography.

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

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.

To determine if a human fibroblast-derived dermal substitute could promote the healing of diabetic foot ulcers. A randomized, controlled, multicenter study was undertaken at 35 centers throughout the U.S. and enrolled 314 patients to evaluate complete wound closure by 12 weeks. Patients were randomized to either the Dermagraft treatment group or control (conventional therapy). Except for the application of Dermagraft, treatment of study ulcers was identical for patients in both groups. All patients received pressure-reducing footwear and were allowed to be ambulatory during the study. The results demonstrated that patients with chronic diabetic foot ulcers of >6 weeks duration experienced a significant clinical benefit when treated with Dermagraft versus patients treated with conventional therapy alone. With regard to complete wound closure by week 12, 30.0% (39 of 130) of Dermagraft patients healed compared with 18.3% (21 of 115) of control patients (P = 0.023). The overall incidence of adverse events was similar for both the Dermagraft and control groups, but the Dermagraft group experienced significantly fewer ulcer-related adverse events. The data from this study show that Dermagraft is a safe and effective treatment for chronic diabetic foot ulcers.

The current state of knowledge is reviewed with respect to the realization of lower limbs venous mapping. Venous mapping is obtained by the use of color and spectral Doppler ultrasound. Doppler ultrasound has provided a precise graphical representation of the superficial and deep venous systems. The performance of the venous mapping is considered essential for the correct handling of venous diseases. The anatomical and pathophysiological basic concepts are defined to realize the sonographic assessment of the veins of the lower limbs. The required technical aspects are revised for the realization of sonographic exploration of the patient with venous insufficiency. Sonographic findings are characterized to support the diagnostic of venous insufficiency of the lower limbs. The CEAP (clinical-etiologic-anatomic-pathophysiologic) classification is utilized to differentiate forms and degrees of severity of the disorder, and has allowed an interinstitutional comparison in clinical studies, the evaluation of treatment and monitoring of patients. A proposal is designed to perform reports that have served of guide surgical to vascular surgeons [es

2012-01-01

This article provides an executive summary of the lower extremity venous disease (LEVD) evidence-based guideline produced by the WOCN Wound Guidelines Task Force. The target audience for this guideline is health care professionals who specialize in, direct, or provide wound care for patients at risk for or with lower-extremity venous disease. The full guideline opens with an overview of definitions of LEVD, its prevalence, clinical relevance, etiology, related physiology and pathophysiology, and overall management goals for patients at risk for developing venous leg ulcers. A detailed assessment section describes how to conduct a full clinical history and physical examination. Two approaches to interventions are provided: one addresses prevention strategies to reduce the risk of developing LEVD with ulcers. Methods to prevent ulcer recurrence are summarized including compression therapy, adjunctive therapies, medications, and patient education. A second approach presents treatment interventions including wound cleansing, debridement, infection control, antibiotic use, along with management of the periwound skin, nutrition, pain, and edema. This section also discusses limb elevation, surgical options, adjunctive therapies, patient education, and health care provider follow-up. A comprehensive reference list, glossary of terms, and appendices on cellulitis and venous eczema, types of edema, and compression therapy are available at the end of the guideline. This article provides an executive summary of the essential features of the guideline.

Limited accuracy in the clinic diagnosis of deep vein thrombosis (VT) makes such diagnostic tests such as duplex sonography or venography necessary. Exact information on the age and extent of the thrombus are necessary for the clinician to optimize the therapeutric management. The correct diagnosis of calf vein thrombosis and of recurrent VT in patients with postphlebitis changes also has implications for treatment. After exclusion of thrombosis, the radiologist should evaluate the leg for other possible causes of symptoms besides VT. Investigation of the venous sytem also has a role in the diagnosis in patients with suspected pulmonary embolism. In patients with chronic venous insuffficiency the deep venous system should assessed for patency and venous valve function. The superficial veins should be differentiated in segments with sufficient or insufficient venous valves, and it is also necessary to look for insufficiency of the perforrating veins. In patients with superficial phlebitis there is risk of propagation into the deep venous system. (orig.) [de

Compression therapy is standard treatment for venous leg ulcers. The authors prefer multi-layer, multi-component, stiff, high-pressure bandages to treat venous leg ulcers. The Unna boot (UB) is an example of this type of bandage. The aim of this study was to compare the effectiveness and tolerability of UB to a new, two-component bandage. One hundred (100) patients with venous ulcers were randomized into two groups: group A (n = 50) received UB and group B (n = 50) 3M™ Coban™ 2 Layer Compression System (C2L). All patients were followed weekly for 3 months and then monthly until complete healing was achieved. The primary outcomes were: ulcer healing or surface reduction; pain; and exudate control. The secondary outcomes were: ease of application and removal of the bandage, pressure exerted in the supine and standing position after application and before removal, and bandage comfort. C2L was associated with 100% ulcer healing; 47 out of 50 cases healed within the first 3 months after application of the bandage. Compared with the UB, there was no statistically significant difference. In both groups the effect of compression on pain and overall well being was excellent; pain decreased by 50% within 1-2 weeks and remained low throughout the duration of treatment and overall well being improved significantly. There was no significant difference between the two systems concerning level of comfort. C2L proved to be effective in treating venous ulcers due to its stiffness and pressure. Its effectiveness was similar to UB, which is often considered the gold-standard compression device for venous ulcers. This fact, in combination with high tolerability and ease of application and removal, make this new bandage particularly suitable for the treatment of venous leg ulcers. .

Hot topics in venous ulcer treatment: an international survey

Full Text Available Compression is the most effective treatment to promote skin ulcer healing, although there are as many different methods of performing a leg compression as the number of phlebologists, each one having personal tricks, solutions, habits. Conversely, though dressings may be done in different ways, none is considered the standard solution. We asked few (18 questions to physicians involved in this field, in Italy and abroad, looking for some common feature. The analysis of 100 replies indicated the average treatment: compression made by multilayer bandage when edema is present, knee long stocking when edema is removed, mostly based on patient’s agreement. Escharectomy should be done when ulcer bed is covered by necrotic tissue. Advanced wound care is used, with dressing changed several times a week. For highly exuding ulcers, a specific dressing is used or frequent changing is performed. The treatment in early stage of disease is done by the physician while subsequently the dressings may be performed by the patient himself, nurses or doctors. Usually no medical treatments are associated. The cost of a single dressing is often lower than 10 Euro, without any reimbursement. The compression devices aren’t reimbursed as well. The expected compression pressure is 30/40 mm Hg. Daytime compression is not reduced at night-time. The patient is always invited to walk. The same compression is used if the ABPI is <1. However the survey shows that several variations in the cookbook may occur, sometimes even contradictory.

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...

Risk factors for chronic cerebrospinal venous insufficiency (CCSVI in a large cohort of volunteers.

Directory of Open Access Journals (Sweden)

Kresimir Dolic

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

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

Deregulation of epidermal stem cell niche contributes to pathogenesis of non-healing venous ulcers

The epidermis is maintained by epidermal stem cells (ESC) that reside in distinct niches and contribute to homeostasis and wound closure. Keratinocytes at the non-healing edges of venous ulcers (VUs) are healing-incompetent, hyper-proliferative and non-migratory suggesting deregulation of ESCs. To date genes which regulate ESC niches have been studied in mice only. Utilizing microarray analysis of VU non-healing edges, we identified changes in expression of genes harboring regulation of ESCs and their fate. In a prospective clinical study of ten VUs, we confirmed suppression of the bone morphogenetic protein receptor and GATA binding protein3 as well as inhibitors of DNA-binding proteins 2 and 4. We also found decreased levels of phosphorylated glycogen synthase kinase 3, nuclear presence of ß-catenin and overexpression of its transcriptional target, c-myc indicating activation of the Wnt pathway. Additionally, we found down-regulation of leucine-rich repeats and immunoglobulin-like domains protein 1, a gene important for maintaining ESCs in a quiescent state, and absence of keratin 15, a marker of the basal stem cell compartment suggesting local depletion of ESCs. Our study shows that loss of genes important for regulation of ESCs and their fate along with activation of ß-catenin and c-myc in the VU may contribute to ESC deprivation and a hyper-proliferative, non-migratory, healing incapable wound edge.

Full Text Available Objective. The analysis of the literature has shown that in patients with chronic non-ulcerative colitis, there were isolated E.coli that cause dysentery-like, cholera-like diseases and escherichioses. Thus, the aim of our study was to establish the level of persistence of enteropathogenic Escherichia in the colon of patients with chronic non-ulcerative colitis and their importance in the ecological system «macroorganism — microbiota». Material and methods. During 2000–2015, there has been conducted a bacteriological examination of the colon content in patients with chronic non-ulcerative colitis aged 27–41 years (average age 37.74 ± 3.62 years. The resulting cultures were examined in the indicative agglutination tests with OKA polyvalent serum. Positive cultures were tested with polyvalent serum of narrow spectrum ОКВ, ОКС, ОКD and ОКЕ. Results. In patients, in colon cavity of which E.coli O18ac:K77; O26:K60; O55:K59; O128ab:K67 were detected, the disease occurs by nosology of colienteritis. In those patients, in whom O25:K11; O144:K; O124:K72 serotypes have been identified, disease occurred as bacterial dysentery, and O25:K11 and O128:K67 — in chole­ra-like form. Discussion. In 94.50 % of patients, common E.coli were detected, but in 55 (35.03 % of them enteropathogenic Escherichia persist, in 41 (26.11 % — E.coli Hly+, in 37 (23.57 % — E.coli Lac–, in 18 (11.46 % — enterotoxigenic E.coli, in 14 (8.42 % — enteroinvasive, and in 11 (7.01 % — enterohemorragic Escherichia. Conclusions. It was determined that the main serotypes of opportunistic Escherichia, which colonize and persist in the colon cavity of patients with chronic non-ulcerative colitis, were O114:K90; O25:K11; O124:K72; O128:K67; O18ac:K77, the persistence of which affects clinical manifestation from colitis to dysentery-like or cholera-like disease.

Wound care matrices for chronic leg ulcers: role in therapy

Directory of Open Access Journals (Sweden)

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

Over recent decades, both the incidence and prevalence of chronic inflammatory bowel disease have continued to rise in industrialized countries; the disease is frequently associated with extracutaneous involvement and comorbidity. The purpose of this work was to investigate the frequency and specificity of mucocutaneous manifestations in Crohn's disease (CD) and ulcerative colitis (UC). An extensive search in peer-reviewed journals via PubMed was performed; presented is a summary and analysis of various studies and data, including data of patients treated at our department. CD and UC are frequently associated with mucocutaneous symptoms; however, primary/specific disease-associations are exclusively seen in CD patients. These include peri-anal and -stomal fistulas and ulcerations, "metastatic" Crohn's disease as well as oral granulomatous disease. Moreover, in both CD and UC, there occur several other inflammatory skin conditions such as erythema nodosum, pyoderma gangrenosum, hidradenitis suppurativa, chronic oral aphthous disease, Sweet syndrome, pyostomatitis vegetans, and bowel-associated dermatosis-arthritis syndrome. Malnutrition syndromes (zinc and vitamin deficiencies) are only rarely observed. On skin and oral/genital mucous membranes various different inflammatory manifestations may be observed during the course of CD or UC. However, most data about a direct pathogenic relationship of the gastrointestinal and dermatologic disorders are quite heterogeneous or even contradictory. Nevertheless, knowledge of these conditions and their possible association with CD and UC could be crucial for early diagnosis and initiation of an appropriate therapy and thus be essential to prevent secondary tissue damage.

Desulfovibrio bacterial species are increased in ulcerative colitis.

Rowan, Fiachra

2012-02-01

BACKGROUND: Debate persists regarding the role of Desulfovibrio subspecies in ulcerative colitis. Combined microscopic and molecular techniques enable this issue to be investigated by allowing precise enumeration of specific bacterial species within the colonic mucous gel. The aim of this study was to combine laser capture microdissection and quantitative polymerase chain reaction to determine Desulfovibrio copy number in crypt-associated mucous gel in health and in acute and chronic ulcerative colitis. METHODS: Colonic mucosal biopsies were harvested from healthy controls (n = 19) and patients with acute (n = 10) or chronic (n = 10) ulcerative colitis. Crypt-associated mucous gel was obtained by laser capture microdissection throughout the colon. Pan-bacterial 16S rRNA and Desulfovibrio copy number\\/mm were obtained by polymerase chain reaction at each locus. Bacterial copy numbers were interrogated for correlation with location and disease activity. Data were evaluated using a combination of ordinary linear methods and linear mixed-effects models to cater for multiple interactions. RESULTS: Desulfovibrio positivity was significantly increased in acute and chronic ulcerative colitis at multiple levels within the colon, and after normalization with total bacterial signal, the relative Desulfovibrio load was increased in acute colitis compared with controls. Desulfovibrio counts did not significantly correlate with age, disease duration, or disease activity but interlevel correlations were found in adjacent colonic segments in the healthy control and chronic ulcerative colitis groups. CONCLUSION: The presence of Desulfovibrio subspecies is increased in ulcerative colitis and the data presented suggest that these bacteria represent an increased percentage of the colonic microbiome in acute ulcerative colitis.

Full Text Available Steve Gist, Iris Tio-Matos, Sharon Falzgraf, Shirley Cameron, Michael BeebeGeriatrics and Extended Care, Programs, VA Puget Sound Health Care Systems, American Lake Division, Tacoma, WA, USAAbstract: With our aging population, chronic diseases that compromise skin integrity such as diabetes, peripheral vascular disease (venous hypertension, arterial insufficiency are becoming increasingly common. Skin breakdown with ulcer and chronic wound formation is a frequent consequence of these diseases. Types of ulcers include pressure ulcers, vascular ulcers (arterial and venous hypertension, and neuropathic ulcers. Treatment of these ulcers involves recognizing the four stages of healing: coagulation, inflammation, proliferation, and maturation. Chronic wounds are frequently stalled in the inflammatory stage. Moving past the inflammation stage requires considering the bacterial burden, necrotic tissue, and moisture balance of the wound being treated. Bacterial overgrowth or infection needs to be treated with topical or systemic agents. In most cases, necrotic tissue needs to be debrided and moisture balance needs to be addressed by wetting dry tissue and drying wet tissue. Special dressings have been developed to accomplish these tasks. They include films, hydrocolloids, hydrogel dressings, foams, hydro-fibers, composite and alginate dressings.Keywords: wound care, pressure ulcers, vascular ulcers, diabetic ulcers, debridement, elderly

[Compression therapy: Choosing the right option for leg ulcers in 2016].

Senet, P; Monfort, J-B; Debure, C

2016-09-01

Compression therapy is a mandatory treatment of leg ulcers whether the goal is cure (stage C6 in the international classification for chronic venous disease) or prevention of recurrence (stage C5). Different indications for compression therapy were proposed by the French Superior Health Authority (HAS) in 2010, but new studies have modified attitudes since that time. Considering the very large number of options available, the many co-morbid conditions observed in these patients, as well as patient age and available assistance, it is important to adapt to the variable clinical and social situations encountered. One must keep in mind that a well-controlled treatment should improve trophic disorders and patient comfort. A poorly-adapted treatment with little or even deleterious effect will be abandoned by the patient. Copyright © 2016. Published by Elsevier Masson SAS.

Current concepts in repair of extremity venous injury.

Science.gov (United States)

Williams, Timothy K; Clouse, W Darrin

2016-04-01

Extremity venous injury management remains controversial. The purpose of this communication is to offer perspective as well as experiential and technical insight into extremity venous injury repair. Available literature is reviewed and discussed. Historical context is provided. Indication, the decision process for repair, including technical conduct, is delineated. In particular, the authors' experiences in both civilian and wartime injury are used for perspective. Extremity venous injury repair was championed within data from the Vietnam Vascular Registry. However, patterns of extremity venous injury differ between combat and civilian settings. Since Vietnam, civilian descriptive series opine the benefits and potential complications associated with both venous injury repair and ligation. These surround extremity edema, chronic venous insufficiency, thromboembolism, and limb loss. Whereas no clear superiority in either approach has been identified to date, there appears to be no increased risk of pulmonary embolism or chronic venous changes with repair. Newer data from the wars in Iraq and Afghanistan and meta-analysis have reinforced this and also have suggested limb salvage benefit for extremity venous repair in combined arterial and venous injuries in modern settings. The patient's physiologic state and associated injury drive five triage categories suggesting vein injury management. Vein repair thrombosis occurs in a significant proportion, yet many recanalize and possibly have a positive impact on limb venous return. Further, early decompression favors reduced blood loss, acute edema, and inflammation, supporting collateral development. Large soft tissue injury minimizing collateral capacity increases the importance of repair. Constructs of repair are varied with modest differences in patency. Venous shunting is feasible, but specific roles remain nebulous. An aggressive posture toward extremity venous injury repair seems justified today because of the likely

Thirty-Day Hospital Readmission After Restorative Proctocolectomy and Ileal Pouch Anal Anastomosis for Chronic Ulcerative Colitis at a High-Volume Center.

Ileal pouch anal anastomosis (IPAA) is associated with a high 30-day hospital readmission rate. Risk factors and etiology of readmission remain poorly defined. We sought to determine the 30-day hospital readmission rate following IPAA at a high-volume center and identify any modifiable perioperative factors. A retrospective review of all patients undergoing two- or three-stage IPAA for chronic ulcerative colitis at our institution between 2002 and 2013 was performed. Analysis was performed on rate of readmission, readmission diagnosis, intervention performed upon readmission, and risk factors for readmission. Thirty-day primary and secondary readmission rates after IPAA were 20.3% (n = 185) and 2.1% (n = 19), respectively. The leading etiologies for readmission included partial small bowel obstruction/ileus (n = 52, 21.9%), pelvic sepsis (n = 43, 18.1%), dehydration (n = 42, 17.7%), and venous thromboembolism (n = 31, 13.1%). While the majority of readmissions were managed medically (n = 119, 65.4%), 19.2% (n = 35) required radiologic intervention and 15.3% (n = 28) required a return to the operating room. On univariate analysis, younger age (p = 0.03) and female sex (p = 0.04) had a significantly increased risk of readmission. On multivariable analysis, BMI ≥ 30 (OR 0.51; 95% CI, 0.25-0.97, p = 0.04) was protective of readmission. Thirty-day hospital readmission following IPAA remains a common problem. Preventable etiologies of readmission include dehydration and venous thromboembolism (VTE). Future quality improvement efforts should focus on education regarding stoma output and extended VTE prophylaxis to decrease hospital readmission rates following IPAA.

Compression Stockings and Pressure Ulcers: Case Series of a Neglected Issue.

Rathore, Farooq A; Ahmad, Faria; Khan, Omer J

2017-10-10

Pressure ulcers develop in patients who endure long periods of immobilization, often caused by conditions such as musculoskeletal and neurological diseases. Pressure ulcers adversely affect the patient and increase caregiver burden and healthcare costs. Typical sites for these ulcers include the sacrum, trochanters, and heels; they also occur on the nape of the neck, penis, nostrils, helix of the ear, and upper back. Compression stockings are commonly used to prevent and stop the progression of venous disorders, including deep vein thrombosis, but their role in the development of pressure ulcers is not well known. We describe three case reports of pressure ulcer development due to prolonged application of compression stockings. In each case, the nursing staff who were primarily responsible for the prevention of pressure ulcers applied the stockings continuously without any intermittent relief. Moreover, the stockings did not include manufacturer instructions, such as recommended exposure times and applications. We recommend that nursing staff be trained in pressure relief and prevention of pressure ulcers, including rare occurrences, and that manufacturers give detailed guidance regarding the safe use of compression stockings.

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

Recent research suggests that statins might be useful in the process of wound healing, playing a positive immune-modulatory role, improving microvascular function and reducing oxidative stress. The aim of this pilot study was to evaluate the efficacy of topic application of Simvastatin-based cream in the treatment of chronic vascular cutaneous ulcers, comparing this type of treatment to a collagen-based dressing, proven to be effective for ulcer treatment. A total of 20 ulcers were studied in 2 Groups of randomly-chosen patients for a period of one month. In the first Group a 0.5% Simvastatin-based cream was topically administered, while the second Group (control) was treated with an absorbable type I bovine collagen-based medication. Each week, wound healing progress was observed in both Groups, and the ulcers photographed. Wound healing rate was calculated by considering the absolute change in area and by the formula "healing ratio (%) = [(Area 0 - Area t4 )/Area 0 ] × 100," both sets of data being related to the days comprised in the study in order to calculate healing rate per day. Statistical analysis was performed by Student t test. Study endpoint equaling the time-course changes of ulcer areas. At the end of the study, when considering absolute change in area, the experimental Group appeared to heal better and faster than the control Group although differences between the Groups were not statistically significant. Conversely, rates of wound healing in the experimental and control Groups were 46.88% and 64% respectively, revealing statistically significant differences. ( P topic application of a simvastatin-based cream proved to be well- tolerated but not effective in the management of vascular leg ulcers in a 4 week-period.

Electrical stimulation (ES) has been tested for decades to improve chronic wound healing. However, uncertainty remains on the magnitude of the efficacy and on the best applicable protocol. We conducted an effect size meta-analysis to assess the overall efficacy of ES on wound healing, to compare the efficacy of the different modalities of electrical stimulation, and to determine whether efficacy differs depending on the wound etiology, size, and age of the chronic wound. Twenty-nine randomized clinical trials with 1,510 patients and 1,753 ulcers were selected. Overall efficacy of ES on would healing was a 0.72 SMD (95% CI: 0.48, 1) corresponding to a moderate to large effect size. We found that unidirectional high voltage pulsed current (HVPC) with the active electrode over the wound was the best evidence-based protocol to improve wound healing with a 0.8 SMD (95% CI: 0.38, 1.21), while evaluation of the efficacy of direct current was limited by the small number of studies. ES was more effective on pressure ulcers compared to venous and diabetic ulcers, and efficacy trended to be inversely associated with the wound size and duration. This study confirms the overall efficacy of ES to enhance healing of chronic wounds and highlights the superiority of HVPC over other type of currents, which is more effective on pressure ulcers, and inversely associated with the wound size and duration. This will enable to standardize future ES practices. © 2017 by the Wound Healing Society.

Full Text Available Abstract Background Chronic wound pathogenic biofilms are host-pathogen environments that colonize and exist as a cohabitation of many bacterial species. These bacterial populations cooperate to promote their own survival and the chronic nature of the infection. Few studies have performed extensive surveys of the bacterial populations that occur within different types of chronic wound biofilms. The use of 3 separate16S-based molecular amplifications followed by pyrosequencing, shotgun Sanger sequencing, and denaturing gradient gel electrophoresis were utilized to survey the major populations of bacteria that occur in the pathogenic biofilms of three types of chronic wound types: diabetic foot ulcers (D, venous leg ulcers (V, and pressure ulcers (P. Results There are specific major populations of bacteria that were evident in the biofilms of all chronic wound types, including Staphylococcus, Pseudomonas, Peptoniphilus, Enterobacter, Stenotrophomonas, Finegoldia, and Serratia spp. Each of the wound types reveals marked differences in bacterial populations, such as pressure ulcers in which 62% of the populations were identified as obligate anaerobes. There were also populations of bacteria that were identified but not recognized as wound pathogens, such as Abiotrophia para-adiacens and Rhodopseudomonas spp. Results of molecular analyses were also compared to those obtained using traditional culture-based diagnostics. Only in one wound type did culture methods correctly identify the primary bacterial population indicating the need for improved diagnostic methods. Conclusion If clinicians can gain a better understanding of the wound's microbiota, it will give them a greater understanding of the wound's ecology and will allow them to better manage healing of the wound improving the prognosis of patients. This research highlights the necessity to begin evaluating, studying, and treating chronic wound pathogenic biofilms as multi-species entities in

Iliofemoral and iliocaval interventions in deep venous thrombosis

International Nuclear Information System (INIS)

Haage, P.; Guenther, R.W.

2005-01-01

Significant spontaneous thrombus disintegration in deep venous thrombosis (DVT) occurs very infrequently. On the contrary, these thrombi are prone to appositional growth and migration into the pulmonary arteries. The development of chronic venous insufficiency due to post-thrombotic syndrome is a frequent consequence of DVT. Therapeutic options in DVT include anticoagulation and recanalising procedures such as thrombolysis and thrombectomy. After appropriate indication assessment, the interventional radiologist can offer an efficacy-proven minimally-invasive vessel restitution approach by performing locoregional thrombolysis, pharmacomechanical therapy or, particularly in iliocaval thrombosis, mechanical thrombectomy. These methods not only serve to restitute of vessel patency, but also allow preserving venous valve function. In DVT with recurrent pulmonary embolism, retrievable filters with extended implantation duration can be deployed. In chronic proximal venous flow obstruction or in case of significant residual stenosis after thrombolysis, balloon angioplasty with stent implantation is the treatment modality of choice. Consequently, the radiologist can adopt an important role in the treatment of extensive venous disease. In this article, the treatment modalities concerning iliofemoral and iliocaval thrombosis are demonstrated and illustrated. (orig.)

Leg ulcers of different etiology disable up to 1% of total population, and up to 15% individuals over 70 years old. It is an old disease, which troubles the patients and medical personnel and is hard to cure. It might take several years to cure the ulcer fully. Most of the patients with leg ulcers are being treated at home, not in the outpatient departments or hospitals; therefore there is not much information on how the ulcer affects the patient's everyday life and its quality. The researchers often analyze only the financial part of this disorder forgetting its human part: pain, social isolation, and decreased mobility. There are many questionnaires and methods to analyze the quality of life of the patients with leg ulceration. It is often unclear if we should treat the ulcer conservatively for a long time or if part of resources should be used for operation (skin grafting) and the time of treatment should be shortened. To see the advantage of both methods and the influence of the ulcer treatment to the quality of life we decided to estimate the functionality of surgical and conservative treatment. We have analyzed the case histories and the data of special questionnaires of 44 patients, which were treated in Department of Plastic Surgery and Burns of Kaunas University of Medicine Hospital in the period of 2001 January-2004 February and had large trophic leg ulcers (m=254 cm2) for 6 months or more. Ten patients were treated conservatively and 34 patients were treated by skin grafting. All of them were interviewed after 3-6 months. We found that the pain in the place of the ulcers has decreased for the patients, who were treated surgically. By making the differences of the pain more exact we found out, that the patients have been feeling pain before the operation and when interviewing them the second time they told that they felt discomfort, not pain. The intensity of pain remained the same for the patients treated conservatively. The regression of pain also

Background Leg ulcers are a common cause of morbidity and disability and result in significant health and social care expenditure. The UK National Institute for Health and Care Excellence (NICE) Clinical Guideline (CG)168, published in July 2013, sought to improve care of patients with leg ulcers, recommending that patients with a break in the skin below the knee that had not healed within two weeks be referred to a specialist vascular service for diagnosis and management. Aim Determine the impact of CG168 on referrals to a leg ulcer service. Methods Patients referred with leg ulceration during an 18-month period prior to CG168 (January 2012-June 2013) and an 18-month period commencing six months after (January 2014-June 2015) publication of CG168 were compared. Results There was a two-fold increase in referrals (181 patients, 220 legs vs. 385 patients, 453 legs) but no change in mean age, gender or median-duration of ulcer at referral (16.6 vs. 16.2 weeks). Mean-time from referral to specialist appointment increased (4.8 vs. 6 weeks, p = 0.0001), as did legs with superficial venous insufficiency (SVI) (36% vs. 44%, p = 0.05). There was a trend towards more SVI endovenous interventions (32% vs. 39%, p = 0.271) with an increase in endothermal (2 vs. 32 legs, p = 0.001) but no change in sclerotherapy (24 vs. 51 legs) treatments. In both groups, 62% legs had compression. There was a reduction in legs treated conservatively with simple dressings (26% vs. 15%, p = 0.0006). Conclusions Since CG168, there has been a considerable increase in leg ulcer referrals. However, patients are still not referred until ulceration has been present for many months. Although many ulcers are multi-factorial and the mainstay of treatment remains compression, there has been an increase in SVI endovenous intervention. Further efforts are required to persuade community practitioners to refer patients earlier, to educate patients and encourage further investment in

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.

Aim: To study the association of Helicobacter pylori infection with chronic antral gastritis in peptic ulcer disease patients and healthy population of Kashmir. Methods: 50 peptic ulcer patients (duodenal ulcer = 46, gastric ulcer = 2 and combined duodenal and gastric ulcer = 2) and 30 asymptomatic healthy volunteers were included in this study. Peptic ulcer was diagnosed on endoscopic examination. 4–6 punch biopsies were taken from gastric antrum in all the individuals and in case of gastric ulcer an additional biopsy was taken from the edge of the ulcer to exclude its malignant nature. Helicobacter pylori (H. pylori) organism was diagnosed using three different test methods, viz. Histology (using Giemsa Stain), Microbiology (Gram Stain) and Biochemistry (using one minute Endoscopy Room Test). Histological diagnosis of H. pylori was taken as the “gold standard” for the presence of H. pylori organism. Histological diagnosis of gastritis was made using Hematoxylin and Eosin Stain and the gastritis was classified as active chronic gastritis and superficial chronic gastritis. Results: Out of 30 peptic ulcer disease patients with associated antral gastritis, 27 (90%) were positive for H. pylori on histological examination (13 superficial chronic gastritis and 14 active chronic gastritis) whereas out of 8 healthy volunteers with histological evidence of chronic antral gastritis, H. pylori was observed in 7 individuals (87.50%) (4 active chronic gastritis and 3 superficial chronic gastritis). Conclusion: A highly significant association between H. pylori infection with chronic antral gastritis both in peptic ulcer disease patients and healthy volunteers of Kashmir was found in this study. Association between H. pylori infection and chronic gastritis was 90% in peptic ulcer group and 87.50% in healthy population (P<0.005). PMID:18493464

Patients and methods: Secondary analysis was performed, using existing data obtained from April to November 2010, for patients with VLU. Thermographic images of wounds and their surrounding area were classified according to the periwound temperature pattern as "normal temperature" or "high temperature". These results were compared with the self-reported pain intensity assessed by the short-form McGill Pain Questionnaire. Cohen's kappa coefficients were used to evaluate the interrater reliability for temperature assessment, and Wilcoxon rank sum test was used to compare pain intensities between the two groups. Results: Among 39 thermographic examinations in eight patients, 22 were classified into the high-temperature group and 17 into the normal-temperature group. Kappa coefficients for the temperature classification were 0.90 between the wound, ostomy, and continence nurse and a wound care specialist, and 0.90 between the wound, ostomy, and continence nurse and a graduate student. The pain rating index (Z=−2.981, P=0.003, sensory pain (Z=−3.083, P=0.002, affective pain (Z=−2.764, P=0.006, and present pain intensity (Z=−2.639, P=0.006 ratings were significantly higher in the high-temperature group than in the normal-temperature group, but the visual analog scale (Z=−0.632, P=0.527 was not significantly different between the two groups. Conclusion: Thermographic pattern may reflect VLU

Procalcitonin (PCT) has been recently accepted as a marker for diagnosing infection. The aim of the present study was to determine whether PCT levels are associated with infection severity of diabetic foot ulcers and whether PCT levels would be helpful to differentiate infected diabetic foot ulcer (IDFU) from IDFU associated with other infectious diseases (IDFU+O). We prospectively included 123 diabetic patients hospitalized for IDFU. Infection severity of diabetic foot ulcers was graded according to the Infectious Diseases Society of America-International Working Group on the Diabetic Foot clinical classification of diabetic foot infection. Chest radiograph, urinalysis, urine microscopy, urine culture, and blood cultures (if fever was present) were performed for all patients to diagnose other infectious diseases. Laboratory parameters were measured from blood venous samples. PCT (Spearman's ρ=0.338, Pdiabetic foot ulcers. However, only PCT levels could differentiate patients with associated infectious diseases from patients with no concomitant infection (area under the receiver-operator characteristic curve 0.869, Pdiabetic foot ulcers and PCT levels>0.59ng/mL in patients with IDFU may be associated with other systemic bacterial infection.

Peptic ulcer is a common disease affecting millions of people every year. Despite improved understanding and treatment of the disease, the number of patients admitted with duodenal peptic ulcer perforation has not decreased. Deaths from peptic ulcer disease overcome other common emergency situations. Laparoscopic repair of the perforated peptic ulcer (PPU) is the gold standard approach for simple perforation. However, in patients with large perforated chronic ulcers laparotomy with pyloroplasty is the standard treatment. It is generally accepted to perform open surgery in PPU emergencies because of the greater knowledge and experience gathered over the past decades and less potential harm for the patient or surgical complications. We present a case of successful laparoscopic pyloroplasty of a perforated duodenal ulcer with stenosis.

2012-01-01

Full Text Available Introduction. 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. Objective. 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. Methods. 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. Results. 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 (p<0.001. Conclusion. When we cannot provide arterial 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,O2 and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

Since the original report of Crohn and Rosenberg (1928) the association between long-standing ulcerative colitis and later development of colonic malignancy has been well known. There are many risk factors for the development of malignancy such as duration, extent, severity and age of the onset of ulcerative colitis, drugs and diagnostic radiation. The dysplasia of the colonic mucosa as a precancerous change are seen not only in the area of malignant focus but also in distant locations in long-standing ulcerative colitis. We present a case of malignant change occurred in a patient with long-standing ulcerative colitis in the rectosigmoid junction. This is probably the first documentation of malignant transformation of ulcerative colitis in the Korean literature.

The application of autologous lipotransfer (fat grafting, lipofilling) in reconstructive surgery is steadily becoming more popular as evidence of the regenerative and reparative effects of fat becomes better known. The authors investigated the use of autologous lipotransfer for treatment of chronic diabetic and other foot and lower limb ulcers. Twenty-six patients with nonhealing wounds were treated with surgical débridement and autologous lipotransfer (using the débridement and autologous lipotransfer method). The mean age of the wounds before intervention was 16.7 months. Wound size after débridement averaged 5.1 ± 2.6 cm2. On average, 7.1 ± 3.3 cc of lipoaspirate was transferred into the wound area. Twenty-two of 25 wounds (88 percent) healed completely within a mean of 68.0 ± 33.0 days. A reduction of wound size by 50 percent was achieved after an average of 4 weeks. In one patient with an ulcer within particularly scarred tissues on the lower limb, a repeated session of lipotransfer led to complete wound healing after another 4 weeks. The authors describe a simple and useful technique to improve wound healing in diabetic feet and chronic lower limb ulcers with a background of peripheral vascular disease, where other interventional options to achieve wound healing have failed.

Cytokines play important roles in the wound healing process through various signalling pathways. The JAK-STAT pathway is utilised by most cytokines for signal transduction and is regulated by a variety of molecules, including suppressor of cytokine signalling (SOCS) proteins. SOCS are associated with inflammatory diseases and have an impact on cytokines, growth factors and key cell types involved in the wound-healing process. SOCS, a negative regulator of cytokine signalling, may hold the potential to regulate cytokine-induced signalling in the chronic wound-healing process. Wound edge tissues were collected from chronic venous leg ulcer patients and classified as non-healing and healing wounds. The expression pattern of seven SOCSs members, at the transcript and protein level, were examined in these tissues using qPCR and immunohistochemistry. Significantly higher levels of SOCS3 (P=0.0284) and SOCS4 (P=0.0376) in non-healing chronic wounds compared to the healing/healed chronic wounds were observed at the transcript level. Relocalisation of SOCS3 protein in the non-healing wound environment was evident in the investigated chronic biopsies. Thus, the results show that the expression of SOCS transcript indicated that SOCS members may act as a prognostic biomarker of chronic wounds. PMID:27635428

Background: Imaging coronary venous systems to guide transcatheter cardiac interventions are becoming increasingly important, particularly in heart failure patients who are selected for cardiac resynchronization therapy (CRT). Failure of left ventricular (LV) lead placement during the procedure has been attributed to the inability to insert catheters into the coronary sinus and the lack of suitable side branches. Purpose To comparatively assess the value of a 64-detector MDCT examination in visualizing the cardiac veins and evaluating the morphological characteristics of the coronary venous system in patients with and without chronic systolic heart failure (SHF). Material and Methods A 64-detector MDCT examination of the heart was performed in 26 consecutive patients (five women, 21 men; mean age 57.80 +- 12.05 years; range 27-81 years) with chronic SHF. The morphological characteristics of the coronary venous system, such as the diameter, the distances between the venous tributaries, the angle and the tortuosity, were evaluated. The group was compared with a subgroup of 52 subjects without SHF (LV ejection fraction >40%) matched for age, sex, and the risk factors for coronary artery disease. Results: The coronary sinus (CS), great cardiac vein (GCV), anterior interventricular vein (AIV), and posterior interventricular vein (PIV) were visualized in all 78 individuals. The posterior vein of the left ventricle (PVLV) (63/78), left marginal vein (LMV) (72/78), and the small cardiac vein (SCV) (50/78) were visualized in SHF and control patients (p = NS). The lengths between venous tributaries were higher (p > 0.05) and more dilated (P < 0.001 for CS, GCV, AIV, PVLV, LMV; p = 0.001 for PIV) in the cases with SHF compared with the control population. The angle between the CS-GCV axis and the venous branches was wider (p = 0.02 for LMV and PIV, p = 0.001 for PVLV) and did not have any correlation with the LV diameter in cases with SHF. There was no difference between the

Diabetic foot ulcers (DFU) are a major, debilitating complication of diabetes mellitus. Unfortunately, many DFUs are refractory to existing treatments and frequently lead to amputation. The development of more effective therapies has been hampered by the lack of predictive in vitro methods to investigate the mechanisms underlying impaired healing. To address this need for realistic wound-healing models, we established patient-derived fibroblasts from DFUs and site-matched controls and used them to construct three-dimensional (3D) models of chronic wound healing. Incorporation of DFU-derived fibroblasts into these models accurately recapitulated the following key aspects of chronic ulcers: reduced stimulation of angiogenesis, increased keratinocyte proliferation, decreased re-epithelialization, and impaired extracellular matrix deposition. In addition to reflecting clinical attributes of DFUs, the wound-healing potential of DFU fibroblasts demonstrated in this suite of models correlated with in vivo wound closure in mice. Thus, the reported panel of 3D DFU models provides a more biologically relevant platform for elucidating the cell–cell and cell–matrix-related mechanisms responsible for chronic wound pathogenesis and may improve translation of in vitro findings into efficacious clinical applications.

2017-04-01

The post thrombotic syndrome is one of the most dreaded complications of proximal deep vein thrombosis. This syndrome leads to pain and suffering with leg swelling, recalcitrant ulceration and venous claudication which greatly impairs mobility and quality of life. The prevalence can be high in patients with iliofemoral venous involvement particularly in the setting of a proximal venous stenosis, such as occurs in May Thurner syndrome. Anticoagulation alone does not reduce the likelihood of this outcome. Compression therapy may be effective but garment discomfort limits its implementation. Pharmacomechanical thrombectomy, which combines catheter-directed thrombolysis with mechanical thrombus dissolution, provides an attractive treatment strategy for such patients. The rationale and delivery of pharmacomechanical thrombectomy, including patient selection and adjunctive antithrombotic therapy, will be reviewed in addition to tips and tricks for managing difficult patient scenarios. © 2017 John Wiley & Sons Ltd.

Is there a link between the structural impact of thoracic outlet and the development of central venous stenosis?

Central venous stenosis (CVS) is a serious complication for chronic hemodialysis (HD) patients. Previous reports of CVS have focused on prior central venous catheterization, because of the higher prevalence and potential for prevention of such an event. However, recent studies have demonstrated that CVS may also develop without a history of central venous catheterization. Although information about the etiological backgrounds regarding the development of CVS without previous central venous catheterization have gradually accumulated, the clinical impact of the chronic compression of the central venous system by the surrounding structures, which may likely determine the central venous susceptibility to CVS, remains poorly understood. This study proposes the hypothesis that the combination of chronic venous compression at the level of thoracic outlet characterized by the natural physique and elevated venous flow induced by the creation of vascular access should be evaluated as a potential factor for the development of CVS, since they may accelerate the development of venous stenosis, presumably through the stimulation of intimal hyperplasia, and thereby the subclavian venous susceptibility to CVS should be determined.

The aim of this study was to estimate the patterns of care and annual levels of health care resource use attributable to managing venous leg ulcers (VLUs) in clinical practice by the UK's National Health Service (NHS) and the associated costs of patient management. This was a retrospective cohort analysis of the records of 505 patients in The Health Improvement Network (THIN) Database. Patients' characteristics, wound-related health outcomes and health care resource use were quantified, and the total NHS cost of patient management was estimated at 2015/2016 prices. Overall, 53% of all VLUs healed within 12 months, and the mean time to healing was 3·0 months. 13% of patients were never prescribed any recognised compression system, and 78% of their wounds healed. Of the 87% who were prescribed a recognised compression system, 52% of wounds healed. Patients were predominantly managed in the community by nurses with minimal clinical involvement of specialist clinicians. Up to 30% of all the VLUs may have been clinically infected at the time of presentation, and only 22% of patients had an ankle brachial pressure index documented in their records. The mean NHS cost of wound care over 12 months was an estimated £7600 per VLU. However, the cost of managing an unhealed VLU was 4·5 times more than that of managing a healed VLU (£3000 per healed VLU and £13 500 per unhealed VLU). This study provides important insights into a number of aspects of VLU management in clinical practice that have been difficult to ascertain from other studies and provides the best estimate available of NHS resource use and costs with which to inform policy and budgetary decisions. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Objective was to determine the underlying cause of superficial skin ulcers over a 15-year period. A retrospective histopathological analysis of 670 cases of superficial skin ulcers diagnosed in the Dept. of Pathology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria from January 1991 to December 2005. A total of 670 superficial skin ulcers were analyzed. The mail to female gender ratio was 409:261(1.5:1.0) and a peakage frequency of 44.3 %( 297) in the 5th and 6th decades. Spectrum of lesions encountered was categorized into inflammatory, infections, benign and malignant diseases. The malignant lesions were 309 (46.1%), non-specific inflammation 302 (45.1%), granulation tissue 25 (3.7%) and pseudoepitheliomatous hyperplasia 14 (2.1%). A total of 18(2.7%) specific infections were encountered, which included bacterial, fungal and viral infection. Benign lesions were 2(0.3%), comprising of neurofibroma and Bowen's disease. The most common malignant lesion was squamous cell carcinoma 203 (30.3%) with a male to female ratio of 128:75 (1.7:1.0). Of these 161 were well differentiated tumors. The lower limb was the prevalent site distribution of all the ulcers. Superficial ulcers may be harbinger of malignant diseases. Squamous cell carcinoma remains the most common malignant lesion arising from chronic superficial ulcers from our setting. Adequate tissue biopsy and early diagnosis may reduce the attendant morbidity of these ulcers. (author)

Full Text Available Context Morbid obesity is associated with various co-morbidities, including chronic venous insufficiency. Bariatric surgery is the only effective treatment for morbid obesity, but with potential risks and possible complications, including venous thromboembolism. Objective To determine the prevalence of clinical and ultrasonographic signs of chronic venous insufficiency in morbid obese patients in preparation for bariatric surgery and the incidence of post-operative venous thromboembolic disease. Methods Patients on work-up for bariatric surgery of Centro Terapêutico Especializado em Fígado (CETEFI and Pro-Gastro surgical teams of the Hospital Beneficência Portuguesa de São Paulo were included. The analysed data were pre-operative findings for venous insufficiency (CEAP - clinical, etiological, anatomical, physiopathologic - classification and venous ultrassonographic findings, type of surgery (open or laparoscopic, abdominal circumference, body mass index (BMI and post-operative ultrassonography search for venous insufficiency and deep venous thrombosis. Results Between March 2007 and December 2009, 95 patients candidates for bariatric surgery had clinical and duplex scan evaluation of the lower limbs venous system. Of the 95 patients, 53 were submitted to the surgical procedure. There was a predominance of women (77.9%, the average age was 38.5 years, average preoperative weight 124.6 kg and average BMI of 45.5 kg/m2. Regarding obesity, 16.8% were obese, and 83.1% were morbidly obese. In relation to the venous findings, 86.3% of the patients did fit CEAP classification less than 3 and 13.7% greater than or equal to 3. Among the post-operative complications, there were four cases of wound infection. Three patients developed post-operative distal venous thrombosis (7.5%, but no one had clinically manifested pulmonary embolism. Conclusion No relation between BMI, CEAP classification and venous ultrassonographic findings were found. Although

To propose pharmacotherapy of disbacteriosis of gastroduodenal mucous microflora in gastroduodenal inflammation, erosion and ulcer. The study enrolled 30 healthy volunteers, 130 ulcer patients and 36 patients with chronic gastritis (27% of the latter had chronic duodenitis). In addition to general clinical examination, fibrogastroduodenoscopy, we made histological and microbiological examinations of biopsy specimens of the mucosa from different parts of the stomach and duodenum, determined sensitivity of the microflora to antibacterial drugs. We found that recurrent ulcer, chronic gastritis and duodenitis are accompanied with overgrowth of pathogenic microflora in gastric and duodenal mucosa. We developed an effective method of the treatment of gastroduodenal mucosa microflora disbacteriosis in gastroduodenal inflammation, erosion and ulcer including antibacterial, antifungal drugs and probiotics.

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

Full Text Available HIV-seropositive persons are at increased risk of methicillin-resistant Staphylococcus aureus (MRSA. Genital ulcerative disease and sexually transmitted infection with subsequent MRSA infection in HIV-seropositive persons have been documented only once. We report a case of a 44-year-old man who presented to the Infectious Diseases Institute, Kampala, Uganda, with chronic genital ulcer disease and who subsequently developed MRSA urethritis and bacteraemia. This case also demonstrates that persistent genital ulcer disease in HIV-seropositive persons may be as a result of concurrent MRSA infection.

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.

Chronic venous disease (CVD) is a common venous disease of the lower extremities and patients often develop symptoms of itching and skin roughness. An easy to use and objective skin examination was recently developed that allows measurement of the level of stratum corneum content and transepidermal water loss (TEWL), which can indicate the status of the barrier function of the stratum corneum. Previous studies demonstrated that histamine production from mast cells, and tryptase and matrix metalloprotease-9 levels were associated with skin inflammation. This study aimed to clarify the relationship between dry skin and inflammatory mediators that mediate the skin symptoms of CVD subjects. The study enrolled 27 subjects with CVD and a control group consisting of 9 volunteers. The itching onset frequency was higher in women (70.4%) compared with men (50.0%). To analyze the mechanisms involved in itching we measured blood inflammatory mediators pre- and post-sclerotherapy. There was a significant decrease in Substance P, histamine, IgE, and tryptase levels post-sclerotherapy compared with those at pre-sclerotherapy. These levels were associated with the severity of itching. In addition, compared with the control subjects, there was a significant increase in the stratum corneum water content and a decrease in the TEWL in the 27 patients with CVD. This was associated with a decrease in the itching symptoms. Our findings indicate that sclerotherapy decreased levels of inflammatory mediators, increased stratum corneum water content and decreased TEWL, which coincided with reduced itching in CVD patients, indicating they might be therapeutic targets.

Haemophilus ducreyi: from sexually transmitted infection to skin ulcer pathogen.

Lewis, David A; Mitjà, Oriol

2016-02-01

This article provides an overview of the biology, epidemiology, clinical features, diagnostic tests, and treatment of Haemophilus ducreyi infection, with special reference to the decline of chancroid and the recent emergence of H. ducreyi as a pathogen responsible for chronic limb ulceration clinically similar to yaws. Chancroid has declined in importance as a sexually transmitted infection in most countries where it was previously endemic. Chancroid may be caused by either class I or class II H. ducreyi isolates; these two classes diverged from each other approximately 1.95 million years ago. H. ducreyi has recently emerged as a cause of chronic skin ulceration in the Pacific region and Africa. Based on sequencing of whole genomes and defined genetic loci, it appears that the cutaneous H. ducreyi strains diverged from the class I genital strains relatively recently. H. ducreyi should be considered as a major cause of chronic limb ulceration in both adults and children and appropriate molecular diagnostic assays are required to determine ulcer aetiology. The high prevalence of H. ducreyi-related cutaneous ulceration in yaws-endemic countries has challenged the validity of observational surveys to monitor the effectiveness of the WHO's yaws eradication campaign.

Diabetes Mellitus (DM) is known to have many complications. Diabetes and its complications are rapidly becoming the world’s most significant cause of morbidity and mortality, and one of the most distressing is Diabetic Foot Ulcer (DFU). Chronic wound complications are a growing concern worldwide, and the effect is a warning to public health and the economy. The etiology of a DFU is multifaceted, and several components cause added together create a sufficient impact on ulceration: neuropathy, vasculopathy, immunopathy, mechanical stress, and neuroarthropathy. There are many classifications of the diabetic foot. About 50% of patients with foot ulcers due to DM present clinical signs of infection. It is essential to manage multifactorial etiology of DFU to get a good outcome.

Arterial ulcers are produced due to chronic ischemia in lower limbs. This causes a progressive, slow decrease in blood flow and oxygen supply to lower limbs. The main symptom consists of an intermittent claudication, or muscle pain while walking which ceases upon resting, but, when these symptoms appear; this wound usually is advanced and medical professionals basically use surgical, pharmaceutical and local treatments to cure this ulcer. In this article, the author presents a guide to diagnosis, treatment and prevention of arterial ulcers.

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). 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. 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, who are

Ultra sound colored duplex sonography is the preferred method in diagnosing chronic venous disease. Data in children on incidence, indications, and results are lacking. From the total of 9180 duplex investigations performed in our hospital from 2009 to 2012, data on indication and results of the investigation as well as patient characteristics were evaluated retrospectively for the proportion of pediatric patients. Duplex investigations were performed 49 times in 38 children (6-18 years), with an average of 1.3 times (1-6 times) per child. Forty percent showed abnormalities: 17 times deep venous thrombosis was suspected; deep venous thrombosis was objectified in 18%. In the 21 investigations performed for varicosis-related complaints, varicose veins or venous malformations were objectified in 57%. Edema was never a symptom of chronic venous disease. Duplex investigation is not often performed in children. In children with established deep venous thrombosis, a family history with deep venous thrombosis is common. In general, edema was not seen in children with varicose veins and, therefore, does not seem a reliable clinical sign at young age. © The Author(s) 2014.

Central Venous Occlusion in the Hemodialysis Patient.

Krishna, Vinay Narasimha; Eason, Joseph B; Allon, Michael

2016-11-01

Central venous stenosis (CVS) is encountered frequently among hemodialysis patients. Prior ipsilateral central venous catheterization and cardiac rhythm device insertions are common risk factors, but CVS can also occur in the absence of this history. Chronic CVS can cause thrombosis with partial or complete occlusion of the central vein at the site of stenosis. CVS is frequently asymptomatic and identified as an incidental finding during imaging studies. Symptomatic CVS presents most commonly as an upper- or lower-extremity edema ipsilateral to the CVS. Previously unsuspected CVS may become symptomatic after placement of an ipsilateral vascular access. The likelihood of symptomatic CVS may be affected by the central venous catheter (CVC) location; CVC side; duration of CVC dependence; type, location, and blood flow of the ipsilateral access; and extent of collateral veins. Venous angiography is the gold standard for diagnosis. Percutaneous transluminal angioplasty and stent placement can improve the stenosis and alleviate symptoms, but CVS typically recurs frequently, requiring repeated interventions. Refractory symptomatic CVS may require ligation of the ipsilateral vascular access. Because no available treatment option is curative, the goal should be to prevent CVS by minimizing catheters and central vein instrumentation in patients with chronic kidney disease and dialysis patients.

Full Text Available In the present study, the ethanolic root extract of Desmodium gangeticum (L. DC., Fabaceae, (EDG, have been studied in various acute and chronic ulcer mouse models. Oral administration of root extract, significantly decrease the ulcer index and lesion number in a dose dependent manner against ethanol induced acute gastric ulcer in mice. In gastric ulcerated animal that received high dose of 150 mg/kg EDG, the mucosa showed no ulceration with slight focal congestion and the glands appeared normal. Pylorus ligated mice, pretreated with EDG showed significant decrease in ulcerous activity under chronic condition. The highest dose (150 mg/kg of the extract provoked a marked increase in protein and glutathione levels, when compare to control. Furthermore, gastric juice, free acidity and total acid output were inhibited in a dose-dependent manner at p<0.05 level. Our results indicate that the EDG possess gastroprotective activity and increasing regeneration of damaged gastric mucosa and thus safe for human use.

A series of 9 patients of a mean age of 48 years, operated on for compression of the ilio-femoral venous axis is reported. The cause of obstruction was external compression in 3 cases, a retroperitoneal sarcoma in 1 case, and an infrarenal aortic aneurysm in 2. Two patients presented with a Cockett's syndrome, 3 with a chronic ilio-femoral thrombosis, and one with a post-traumatic segmentary stenosis. Treatment consisted in a resection/Dacron grafting of 2 infrarenal aortic aneurysms, one femoro-caval bypass graft, 2 transpositions of the right common iliac artery in the left hypogastric artery for Cockett's syndrome, 3 Palma's operations for chronic thrombosis, and one internal jugular vein interposition for segmentary stenosis. There were no postoperative deaths and no early thromboses of venous reconstructions performed. All the patients were relieved of symptoms during the follow-up period, whose mean length was 38 months. The cause of venous obstruction and the presence of symptoms which are resistant to medical treatment are the main indications to ilio-femoral venous revascularization. The choice of the optimal treatment in each single case yields satisfactory results.

It is widely assumed that central venous stenosis (CVS) is most commonly associated with previous central venous catheterization among the chronic hemodialysis (HD) patients. We evaluated the validity of this assumption in this retrospective study. The clinical records from 2,856 consecutive HD patients with vascular access failure during a 5-year period were reviewed, and a total of 26 patients with symptomatic CVS were identified. Combined with radiological findings, their clinical characteristics were examined. Only seven patients had a history of internal jugular dialysis catheterization. Diagnostic multidetector row computed tomography angiography showed that 7 of the 19 patients with no history of catheterization had left innominate vein stenosis due to extrinsic compression between the sternum and arch vessels. These patients had a shorter period from the time of creation of the vascular access to the initial referral (9.2 ± 7.6 months) than the rest of the patients (35.5 ± 18.6 months, p = 0.0017). Our findings suggest that cases without a history of central venous catheterization may not be rare among the HD patients with symptomatic CVS. However, those still need to be confirm by larger prospective studies of overall chronic HD patients with symptomatic CVS.

Measurement of the healing ability of ischemic ulcers in the lower limbs in chronic arterial obstructive disease using 201Tl-Cl

International Nuclear Information System (INIS)

Motoyasu, Shuzo

1987-01-01

Evaluation of the healing ability of ischemic ulcers by a method involving measurement of the ulcer index (U. I.) and mean ulcer index of toes (mU. I.) using 201 Tl-Cl before and after the treatment of chronic arterial obstructive disease accompanied by ischemic ulcer was studied. The lesions consisted of 56 ulcers in 41 limbs. Reactive hyperemia following avascularization stress was used for measurement, and U. I. was determined according to the method of Siegel et al. For cases with toe ulcers, the mU. I. was measured from plantar scintigrams, twice under stress and upon redistribution after 3 hours' rest. The following results were obtained. 1) The healing ability of the cases with a U. I. value of more than 1.4 was good, but even among cases with a pretreatment U. I. of 0.9 - 1.4, ulcer healing was also good in cases in which the U. I. was maintained above 1.4 as a result of various treatments. 2) Significant increases in U. I. were observed in the arterial reconstruction group after treatment, compared to the conservative treatment group and the lumbar sympathectomy group. 3) The healing ability was good in cases with an mU. I. of more than 1.2 at stress except for 2 ASO cases complicated by diabetes. 4) Although it was difficult to prognosticate the healing ability of cases with an mU. I. of less than 1.2 before treatment, healing ability could be evaluated after treatment on the basis of the appearance of significant increase in blood flow on stress in the ulcerated toes. 5) A stress index seemed to reflect the ischemic conditions in ulcerated toes in relation to stress. 6) U. I. and mU. I. measured using 201 Tl-Cl were significantly correlated with the degree of inflammatory and reactive hyperemia in the floor of ulcers and in the ulcerated toes. (J.P.N.)

Chronic cerebrospinal venous insufficiency in multiple sclerosis: clinical correlates from a multicentre study

2011-10-01

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.

Venous thromboembolism: epidemiology and magnitude of the problem.

Science.gov (United States)

Goldhaber, Samuel Z

2012-09-01

Pulmonary embolism is the third most common cardiovascular disease after myocardial infarction and stroke. The death rate from pulmonary embolism exceeds the death rate from myocardial infarction, because myocardial infarction is much easier to detect and to treat. Among survivors of pulmonary embolism, chronic thromboembolic pulmonary hypertension occurs in 2-4 of every 100 patients. Post-thrombotic syndrome of the legs, characterized by chronic venous insufficiency, occurs in up to half of patients who suffer deep vein thrombosis or pulmonary embolism. We have effective pharmacological regimens using fixed low dose unfractionated or low molecular weight heparin to prevent venous thromboembolism among hospitalized patients. There remains the problem of low rates of utilization of pharmacological prophylaxis. The biggest change in our understanding of the epidemiology of venous thromboembolism is that we now believe that deep vein thrombosis and pulmonary embolism share similar risk factors and pathophysiology with atherothrombosis and coronary artery disease.

Sara Naramore

2015-09-01

Full Text Available Chronic constipation is a common condition which may result in fecal impaction. A 13-year-old male with chronic constipation and encopresis presented with fecal impaction for three weeks. The impaction caused abdominal pain, distension, encopresis, and decreased oral intake. He was found in severe distress with non-pitting edema of his feet and ankles along with perineal edema. The pedal edema worsened after receiving a fluid bolus, so concern arose for venous compression or a thrombus. A Duplex Ultrasound demonstrated changes in the venous waveforms of the bilateral external iliac and common femoral veins without thrombosis. Manual disimpaction and polyethylene glycol 3350 with electrolytes resolved the pedal and perineal edema. Four months later, he had soft bowel movements without recurrence of the edema. A repeat Duplex Ultrasound was normal. We present a child in whom severe fecal impaction caused pelvic venous compression resulting in bilateral pedal and perineal edema.

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.

Full Text Available Background: Chronic venous insufficiency is an important complication following iliofemoral deep venous thrombosis. Early thrombus removal may preserve venous function and prevent this complication. This study represents the largest reported South African series of pharmacomechanical thrombolysis for iliofemoral deep venous thrombosis to date. Objective: To evaluate the long-term outcome following pharmacomechanical thrombolysis for proximal and extensive deep venous thrombosis in a private, specialist vascular unit. Methods: All patients who underwent pharmacomechanical thrombolysis for iliofemoral deep venous thrombosis between August 2009 and January 2016 were invited to return for clinical assessment and venous ultrasound. Clinical findings were recorded according to the Villalta score and clinical, etiology, anatomic and pathology (CEAP classification. The quality of life (QoL was assessed utilising the VEINES-QoL/Sym questionnaire, providing two scores per patient, one describing the QoL and the other symptom severity (Sym. Results: Thirty two patients (35 legs were evaluated. There were 25 females and 7 males, with a mean age of 33.5 years (±14 years. The mean follow-up period was 31 months (range 3 months – 80 months.

Despite continuous improvement in our knowledge and management of chronic venous disease (CVD), certain areas, such as the role of muscarinic receptors in the pathology and treatment of CVD, remain unexplored. The symposium "The place of Ruscus extract, hesperidin methyl chalcone, and vitamin C in the management of CVD", held at the Annual Meeting of the European Venous Forum on 7-9 July 2016 in London, presented an update on the pathophysiology of CVD and highlighted how the combination of Ruscus extract, hesperidin methyl chalcone, and vitamin C (Ruscus/HMC/VitC; Cyclo 3® Fort), may counteract the deleterious processes underlying CVD. The data presented during this symposium are reported here. The pathophysiology of CVD is driven by a complex process involving numerous factors, with the two key players being venous hypertension and the inflammatory response. The cascade of reactions induced by disturbed venous flow, inflammation, and tissue alterations results in the early appearance of symptoms and progressive development of clinical signs of disease. Previous studies have shown that Ruscus extract acts at three levels: on the veins, capillaries and lymphatics, and has anti-inflammatory properties. A series of recent experiments has shed new light on the mechanism of action of the combination of Ruscus/HMC/VitC. The efficacy of Ruscus/HMC/VitC in CVD is supported by clinical studies, while two meta-analyses have confirmed a significant decrease of several symptoms and ankle circumference in response to treatment with this agent, leading to the conclusion that Ruscus/HMC/VitC deserves a Grade A rating.

Chronic wounds, including diabetic foot ulcers (DFU), pressure ulcers (PU), and venous ulcers (VU) result from multiple physiologic impairments. Operative debridement is a mainstay of treatment to remove nonviable tissue and to stimulate wound healing. Unlike tumor resection, however, operative wound specimens are not routinely sent for pathology. The objective of this study was to describe the pathology present in chronic wounds. Pathology reports of the skin edge and wound base from 397 initial debridements in 336 consecutive patients with chronic wounds were retrospectively reviewed. All data were entered and stored in a Wound Electronic Medical Record. Pathology data were extracted from the Wound Electronic Medical Record, coded, and quantified. Up to 15 distinct histopathologic findings across 7 tissue types were observed after review of pathology reports from chronic wounds. Specifically, the pathology of epidermis revealed hyperkeratosis: 66% in DFUs, 31% in PUs, and 29% in VUs. Dermal pathology revealed fibrosis in 49% of DFUs, 30% of PUs, and 15% of VUs. Wound bed pathology revealed necrosis in the subcutaneous tissue in 67% of DFUs, 55% of PUs, and 19% of VUs. Fibrosis was reported in between 19% and 52% of all wound types. Acute osteomyelitis was present in 39% of DFUs, 33% of PUs, and 29% of VUs. This observational study of the histopathology of initial surgical debridement of chronic wounds revealed a wide range of findings across multiple tissue levels. Although certain findings such as osteomyelitis and gangrene have been shown to directly relate to impaired wound healing and amputation, other findings require additional investigation. To rigorously define a margin of debridement, a prospective study relating histopathology and clinical outcomes such as healing rates and amputation is needed.

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

Chronic wounds (VLU: venous leg ulcer, DFU: diabetic foot ulcer, PU: pressure ulcer, or complex wounds) affect a significant proportion of the population. Despite appropriate standard wound care, such ulcers unfortunately may remain open for months or even years. The use of leukocyte- and platelet-rich fibrin (L-PRF) to cure skin ulcers is a simple and inexpensive method, widely used in some countries but unknown or neglected in most others. This auto-controlled prospective cohort study explored and quantified accurately for the first time the adjunctive benefits of topical applications of L-PRF in the management of such refractory ulcers in a diverse group of patients. Forty-four consecutive patients with VLUs (n = 28, 32 wounds: 17 ≤ 10 cm 2 and 15 > 10 cm 2 ), DPUs (n = 9, 10 wounds), PUs (n = 5), or complex wounds (n = 2), all refractory to standard treatment for ≥3 months, received a weekly application of L-PRF membranes. L-PRF was prepared following the original L-PRF method developed more than 15 years ago (400g, 12 minutes) using the Intra-Spin L-PRF centrifuge/system and the XPression box kit (Intra-Lock, Boca Raton, FL, USA; the only CE/FDA cleared system for the preparation of L-PRF). Changes in wound area were recorded longitudinally via digital planimetry. Adverse events and pain levels were also registered. All wounds showed significant improvements after the L-PRF therapy. All VLUs ≤ 10 cm 2 , all DFUs, as well as the two complex wounds showed full closure within a 3-month period. All wounds of patients with VLUs > 10 cm 2 who continued therapy (10 wounds) could be closed, whereas in the five patients who discontinued therapy improvement of wound size was observed. Two out of the five PUs were closed, with improvement in the remaining three patients who again interrupted therapy (surface evolution from 7.35 ± 4.31 cm 2 to 5.78 ± 3.81 cm 2 ). No adverse events were observed. A topical application of L-PRF on

Full Text Available Last January The Lancet published the article by Traboulsee et al. Prevalence of extracranial venous narrowing on catheter venography in people with multiple sclerosis, their sibilings, and unrelated healthy controls: a blinded, case control study. These Authors confirmed the presence of chronic cerebrospinal venous insufficiency with a high prevalence of about 70% in the Canadian population, but without significant differences between patients and healthy controls, yet. However, they used a criterion never published to assess stenosis, in alternative to the classic measurement of the diameter in the segment immediately preceding the narrowest point. Traboulsee et al. measure the stenosis along the entire length of the internal jugular vein, by comparing the maximum diameter with the narrowest point. It has been demonstrated, from normal anatomy findings, how the jugular bulb diameter normally exceeds 50% of the minimum diameter of the internal jugular vein, clearly showing the reason why Traboulsee et al. did not find significant differences between people with multiple sclerosis, their sibilings, and unrelated healthy controls. Furthermore, as the outcome measure of Traboulsee et al., wall stenosis is a neglected part of primary venous obstruction, because in the majority of cases obstruction is the consequence of intraluminal obstacles, as a considerable part of truncular venous malformations, and/or compression; rarely of external hypoplasia. Finally, several recently published methods can be adopted for objective assessment of restricted jugular flow in course of chronic cerebrospinal venous insufficiency, by the means of non invasive magnetic resonance imaging, ultrasound and plethysmography. This may help us in improving the assessment of cerebral venous return in the near future.

This single case report (ABA design) was undertaken as a preliminary investigation into the clinical effects of low intensity laser upon venous ulceration, applied to wound margins only, and the potential relevance of wound debridement and wound measurement techniques to any effects observed. Ethical approval was granted by the University of Ulster's Research Ethical Committee and the patient recruited was required to attend 3 times per week for a total of 8 weeks. Treatments were carried out using single source irradiation (830 nm; 9 J/cm2, CB Medico, Copenhagen, Denmark) in conjunction with dry dressings during each visit. Assessment of wound surface area, wound appearance, and current pain were completed by an independent investigator. Planimetry and digitizing were completed for wound tracings and for photographs to quantify surface areas. Video image analysis was also performed on photographs of wounds. The primary findings were changes in wound appearance, and a decrease in wound surface area (range 33.3-46.3%), dependent on the choice of measurement method. Video image analysis was used, but rejected as an accurate method of wound measurement. Treatment intervention produced a statistically significant reduction in wound area using the C statistic on digitizing data for photographs (at Phase one only; Z = 2.412; p debridement emerged as an important procedure to be carried out prior to measuring wounds. Despite fluctuating pain levels recorded throughout the duration of the study, VAS scores showed a decrease of 15% at the end of the study. This hypoalgesic effect was, however, statistically significant (using the C statistic) at Phase one only (Z = 2.554; p types of ulceration.

To investigate the relationship between pressure ulcers of the heel and peripheral arterial disease (PAD) and determine the feasibility of conducting a statistically powered matched case control study. Evidence indicates a relationship between chronic leg ulcers and vascular disease. The relationship between pressure ulcers of the heel and vascular disease is less well established. A matched case control study. Data were collected between March 2014 and January 2015. 15 patients identified as having a grade 2, 3 or 4 pressure ulcer of the heel were compared with 15 matched controls without pressure ulcers of the heel. The primary clinical outcome measure was the ankle brachial pressure index (ABPI), where an ABPI 1.3 was considered clinically indicative of PAD. The primary feasibility outcome measure was the rate of recruitment. Eighty seven patients were reported as having foot and heel ulcers; 36 of whom were identified as having pressure ulcers of the heel, 15 (42%) of whom were recruited to the study. Patients presenting with pressure ulcers of the heel were significantly more likely to simultaneously have previously undiagnosed PAD compared with age, gender and ethnicity matched controls without pressure ulcers of the heel (odds ratio: 11, 95% confidence interval 1.99-60.57). The formation of pressure ulcers of the heel could, in some patients, be related to the presence of PAD rather than a consequence of poor quality care. Healthcare professionals should assess the patient to exclude or confirm PAD. Copyright © 2016 Tissue Viability Society. Published by Elsevier Ltd. All rights reserved.

A case of skin aspergillosis in the region of radiation ulcer which was caused by Aspergillus fumigatus was reported. The patient was a 51 year-old man. This fungal infection was probably induced by a local factor, that is, chronic radiation ulcer. Histological findings suggested that Aspergillus fumigatus which increased saprophytically at the beginning possessed parasitic nature gradually, invaded into connective tissues in the deep layer of true skin, and made radiation ulcer more intractable.

Full Text Available BACKGROUND This was an open label study. Although, honey has been used for centuries in wound care, now only it is being integrated into modern medical practice. The resurgence of interest in honey as a medicine for modern wound dressing offers opportunities for both patients and clinicians. The aim of this study is to show the advantage of honey dressing over conventional saline dressing in the management of chronic non-healing ulcer. This property of honey is mentioned in papyruses traced to 3500 years ago among ancient Egyptians and the Hebrews 3000 years ago. Honey naturally contains small amounts of enzymes. The predominant enzymes in honey are diastase (amylase, invertase (alpha-glucosidase and glucose oxidase. Honey has been proven to have significant antibacterial properties and is a useful constituent in wound and burn care. The stimulation of cell growth seen with honey is probably also responsible for ‘kick-starting’ the healing process in chronic wounds that have remained non-healing for long periods. Honey has a broad spectrum of activity against bacteria and fungi. Many randomised and non-randomised study has shown the efficacy of honey as a healing agent and excellent dressing material. MATERIALS AND METHODS Study was conducted in medical college, Trivandrum, which is a tertiary care centre. Patients are selected from orthopaedic and general surgical wards. The study period was one year extending from July 2014 to June 2015. Saline dressing was given for the patients admitted in the first 6 months of study. Honey dressing was given for the next 6 months of study. Outcome was assessed on duration of hospital stay, difference of outcome in different distribution of grades of ulcer, difference of outcome in patients with vascular compromise, which is found out by Doppler ultrasound and difference of outcome in patients with diabetes mellitus. RESULTS Most significant observations made were in regard to duration of hospital stay

Ehlers-Danlos Syndrome Type VIII: A Rare Cause of Leg Ulcers in Young Patients

Full Text Available Ehlers-Danlos syndrome type VIII (EDS-VIII is a very rare autosomal dominant disease characterized by early-onset periodontitis associated with features of Ehlers-Danlos syndrome. We report a 32-year-old man whose chronic leg ulcer led to the diagnosis of EDS-VIII. He had severe periodontitis with complete loss of permanent teeth and skin fragility with thin skin, atrophic scars, and brownish atrophic pretibial plaques. Leg ulcer is not a prominent feature of EDS-VIII. We suggest adding EDS-VIII to the list of rare diseases accounting for chronic leg ulcers, if this case report prompts others to report leg ulcers associated with EDS-VIII.

[Ulcerating Herpes simplex infections in intensive care patients].

Fischer, M; Wohlrab, J; Radke, J; Marsch, W C; Soukup, J

2002-11-01

Herpes simplex infections are potentially a life-threatening situation for immunocompromised as well as critically ill patients. The correct diagnosis is made more difficult in comatose patients by the fact that the characteristic symptom of extreme pain cannot be registered. The clinical dermatological findings (polycyclic configuration, easily bleeding ulcers) are thus especially important in patients under intensive care conditions. As examples, the cases of 3 critically ill patients (subarachnoid bleeding or head injury) developing therapy-resistant, flat sacral or perioral skin ulcers with peripheral blisters are presented. Herpes simplex virus was confirmed immunohistologically and in the smear test. All patients subsequently died. These cases emphasize that patients in the intensive care unit are in danger of developing a chronic persistent Herpes simplex infection due to latent immunosuppression. Chronic persistent Herpes infections may be underrated in intensive therapy, and must always be ruled out in case of therapy-resistant erosions or ulcerations.

Full Text Available BACKGROUND Type 2 diabetes mellitus is a chronic disease caused by a combination of lifestyle and genetic factors affecting all organs in the body. Foot ulcers are one of the common and serious long-term complications of diabetes leads to recurrent and chronic infections, which results in limb loss when treatment is delayed. The aim of this study is to find out the clinical outcome and microbiological profile in patients admitted with diabetic foot ulcers. MATERIALS AND METHODS The study conducted between November 2008 to November 2009 over 50 patients with history of foot ulceration and diabetes. 50 patients were admitted with diabetic foot ulcer over a period of one year between November 2008-2009. They were studied after getting written consent. A predesigned pro forma was used to get the parameters comprising age, gender, duration, type of diabetes mellitus, presence of neuropathy, nephropathy (serum creatinine, urine albumin, retinopathy (screening funduscopy by ophthalmologist. RESULTS Among 50 patients admitted and treated for diabetic foot ulcers with mean stay of 18 days, 29 (58% had complete healing on conservative management, 18 (36% underwent minor amputation (toes, 3 (6% had major amputation (below knee/above knee. No mortality among the study groups encountered. Gram-negative aerobes E. coli (36%, Pseudomonas (52%, Klebsiella (28%, Proteus vulgaris (20% and Acinetobacter (16% were most frequently isolated followed by gram-positive aerobes MRSA (14%, Enterococcus (6%, Strep pyogenes (4% and no anaerobic growth. CONCLUSION Diabetic foot infections are frequently polymicrobial and predominantly gram-negative aerobic bacteria at presentation. Multidrug resistance pseudomonas aeruginosa and MRSA in diabetic foot ulcer is at its emergence and life threatening. Initial aggressive multimodal approach with surgical intervention, culture specific and sensitive targeted combined broad-spectrum antibiotics decreases the morbidity and mortality

Chronic ulcer models produced by serosa-searing method are very similar histologically to the ulcer healing process occurring in humans. In an effort to produce a serosa-searing chronic ulcer model in rats, we devised a new balance-type apparatus. This searing apparatus is capable of changing adequately both temperature and duration of time. Furthermore, the pressure which serves to bring the searing iron tip into contact with the stomach serosa surface can also be precisely changed. Optimal conditions for reproducing the serosa-searing ulcer model were at 65 degrees C and in 5 sec. Moreover, in order to evaluate the effects of pressure, various pressure levels (A: 5 g, 17.68 g/cm2; B: 10 g, 35.37 g/cm2; C: 15 g, 53.05 g/cm2; D: 20 g, 70.74 g/cm2; E: 25 g, 88.42 g/cm2; F: 30 g, 106.10 g/cm2; G: 35 g, 123.79 g/cm2 (+/- 1 g, 0.149 g/cm2)) of 5-sec duration at 65 +/- 0.1 degrees C were used. Macroscopically, gastric mucosal lesions were most clearly observed in a pressure-related manner 7 days after the procedure. Histologically, definite deep ulcerations (UI-III or UI-IV) were observed at pressure level C (15 g, 53.05 g/cm2) or more. The highest incidence (87%) of histological gastric ulcers (UI-IV) was observed in pressure level E (25 g, 88.42 g/cm2). The healing process was observed at 40 to 60 days postoperatively. At 100 days after the procedure, recurrences were observed both macroscopically and histologically. In conclusion, this new apparatus is very useful for reproducing a chronic ulcer model for observing the healing and recurrence process.

Full Text Available Chronic gastritis and gastric ulcers are prevalent throughout the world and are considered to be a global health problem. Modified Xiaochaihutang (MXCHT prescription is broadly used in traditional medicine hospital for the treatment of gastritis. In order to assess the anti-Helicobacter pylori (H. pylori effect of MXCHT, agar diffusion method in vitro and fluid dilution method for the minimal inhibitory concentration (MIC were established. The anti-inflammatory effects were then evaluated using mouse ear edema model and rat paw edema model. The ethanol-induced gastric ulcer method was employed to verify the gastroprotective effect of active extracts in MXCHT. HPLC-TOF-MS/MS was used for analyzing the possible active constituents after oral administration of effective extracts in ethanol-induced gastric ulcer models. MXCHT and 4 different extracts of the bacterial inhibition diameter and MIC were dramatically decreased compared with control group, showing anti-Helicobacter pylori effects. High dose groups of MXCHT, water extract, EtOAc extract, and n-BuOH extract displayed significant anti-inflammatory effects in xylene-induced mouse ear edema model and carrageenan-induced rat paw edema model test. MXCHT and all active extracts exhibited gastroprotective activity and prevented gastric lesions induced by ethanol in rats. 4 prototype components and 4 metabolites were identified after oral administration of EtOAc extract. In addition, 6 prototype components and 6 metabolites were identified in n-BuOH extract. MXCHT, EtOAc extract, and n-BuOH extract demonstrate gastroprotective effects through anti-Helicobacter pylori and anti-inflammatory activities. Thus, this prescription may be a suitable natural source for the prevention and treatment of chronic gastritis and gastric ulcers.

Full Text Available Venous ulcer patients can experience this situation for several years without achieving healing if treatment is inadequate. Evidence-based professional practice generates effective results for patients and services. This research aimed to carry out a systematic review to assess the most effective method to improve venous return and the best topic treatment for these ulcers. Studies were collected in eight databases, using the following descriptors: leg ulcer, venous ulcer and similar terms. The sample consisted of 33 primary studies and two Meta-analyses. A wide range of treatments was identified, grouped in compression therapy (54.3% and topical treatment (45.7%. It was evidenced that compression therapy increases ulcer healing rates and should be used in patients with intact arteries. There is no consensus about the best topical treatment, although different options should be associated with compression therapy.Pacientes con úlcera venosa pueden convivir con esta situación durante varios años, sin obtener la cicatrización de la herida caso el tratamiento no sea adecuado.

A method producing persistent gastric ulcers in the rhesus monkey by combined mucosal injury and γ-irradiation was modified and evaluated in the rabbit. γ-Irradiation (800-1000 cGy) immediately after removal of 2-mm-diameter sections of antral mucosa resulted in ulcer craters 5-7 days later. Ulcer sites were characterized by loss of the mucosa, muscularis mucosa, and much of the submucosa. The exposed submucosa was coated with fibrin and necrotic debris infiltrated with heterophils, the rabbit equivalent of neutrophils. These ulcers strongly resemble human chronic gastric ulcers. Binding of Carafate (sucralfate; Marion Laboratories, Inc., Kansas City, MO) and Maalox (magnesia-alumina oral suspension; Wm. H. Rorer, Inc., Ft. Washington, PA) to ulcer and nearby nonulcer sites in the antrum was assessed 1 hour after drug dosing. Drug binding was determined by aluminum quantitation of stomach wall punch biopsies at necropsy. Both drugs significantly increased aluminum bound to the stomach wall compared with vehicle treatment. Significantly more antiulcer drug was bound to ulcer sites than to nearby nonulcer sites only after sucralfate administration. This model of persistent gastric ulcer should be useful to further study gastric ulcer pathogenesis and treatment

During 2005-2007 128 patients at the age from 21 to 80 years with extensive trophic ulcers of legs were treated in the contaminated surgery department of A.V. Vishnevsky Surgery Institute and Korolenko Hospital. In 87 patients (69.9%) varicosity was the cause of venous insufficiency, in 41 patients--post-thrombotic disease. 23 patients (17.97%) had double-sided throphic ulcers. In 50 patients (39.1%) ulcer area exceeded 40 cm2. In microscopical analysis fungi were discovered in 87 patients (89.06%). In the remaining 15 patients diagnosis was verified culturally. System etiotropic antimycotic antibacterial treatment including hyposensitizative, anti-inflammatory, antihistamine drugs was carried out. 34 patients (26.57%) received broad spectrum antibiotic from terbinafine group (Terbizil) in dosage 250 mg once a day during 3 moths with concurrent use of topical antimycotics. 34 patients (26.56%) recieved pulse therapy with broad spectrum antibiotic Rumicoz 400 mg a day during 7 days in combination with topical antimycotics. Nizoral 400 mg a day during 30 days was prescribed to 26 patients (20.3%). 34 patients (26.56%) were treated only with topical antimycotics. After preoperative preparation and reduction of inflammatory process 64 patients had underwent excision of trophic ulcers whereupon the therapy was continued. In these patients regress of varicose eczema manifestation was achieved on the 10th day. In patients who hadn't received surgical cure regress of varicose eczema was signed on the 23-25th day after onset of treatment. Question of plastic closing of throphic ulcers and wounds after their excision was solved particularly. 14 patients needed recurring surgical management becose inflammatory process was continued. Comprehensive approach to therapy taking into account mycotic semination appears to be appropriate and effective. Proactive surgical tactics (excision of throphic ulcer) allows to quicken preoperative preparation for correction of venous blood

Background: venous malformations are congenital lesions that can cause pain, decreased range of movement, compression on adjacent structures, bleeding, consumptive coagulopathy and cosmetic deformity. Sclerotherapy alone or combined with surgical excision is the accepted treatment in symptomatic malformations after failed treatment attempts with tailored compression garments. Objectives: to report our experience with percutaneous sclerotherapy of peripheral venous malformations with ethanol 96%. Patients and methods: 41 sclerotherapy sessions were performed on 21 patients, aged 4-46 years, 15 females and 6 males. Fourteen patients were treated for painful extremity lesions, while five others with face and neck lesions and two with giant chest malformations had treatment for esthetic reasons. All patients had a pre-procedure magnetic resonance imaging (MRI) study. In all patients, 96% ethanol was used as the sclerosant by direct injection using general anesthesia. A minimum of 1-year clinical follow-up was performed. Follow-up imaging studies were performed if clinically indicated. Results: 17 patients showed complete or partial symptomatic improvement after one to nine therapeutic sessions. Four patients with lower extremity lesions continue to suffer from pain and they are considered as a treatment failure. Complications were encountered in five patients, including acute pulmonary hypertension with cardiovascular collapse, pulmonary embolus, skin ulcers (two) and skin blisters. All patients fully recovered. Conclusion: sclerotherapy with 96% ethanol for venous malformations was found to be effective for symptomatic improvement, but serious complications can occur.

2010-07-01

Recent data report that the incidence of peptic ulcer is decreasing in the general population; conversely, the rates of gastric and duodenal ulcer hospitalization and mortality remain very high in older patients. Two major factors that might explain this epidemiological feature in the elderly population are the high prevalence of Helicobacter pylori infection and the increasing prescriptions of gastroduodenal damaging drugs, including NSAIDs and/or aspirin (acetylsalicylic acid). The main goals for treating peptic ulcer disease in old age are to reduce recurrence of the disease and to prevent complications, especially bleeding and perforation. The available treatments for peptic ulcer are essentially based on gastric acid suppression with antisecretory drugs and the eradication of H. pylori infection. The aim of this article is to report the available data on clinical efficacy and tolerability of peptic ulcer treatments in elderly patients and provide recommendations for their optimal use in this special population. Proton pump inhibitor (PPI)-based triple therapies for 7 days are highly effective for the cure of H. pylori-positive peptic ulcers as well as for reducing ulcer recurrence. Antisecretory drugs are also the treatment of choice for NSAID- or aspirin-related peptic ulcers and are useful as preventive therapy in chronic users of NSAIDs and low-dose aspirin as antiplatelet therapy. Antisecretory PPI therapy has a favourable tolerability profile in geriatric patients; however, monitoring is suggested in older patients with frequent pulmonary infections, gastrointestinal malabsorption, unexplained chronic diarrhoea, osteoporosis or those taking concomitant cytochrome P450 2C19-metabolized medications. The overall approach to the geriatric patient should include a comprehensive geriatric assessment that ensures multidimensional evaluation of the patient in order to better define the clinical risk of adverse outcomes in the older patient with peptic ulcer and

To evaluate the efficacy of manual lymphatic drainage (MLD) in improving health-related quality of life (HRQOL), symptomatology, and physical status in patients with chronic venous insufficiency (CVI). Single-blind randomized controlled trial. Health community attendant service. Subjects with CVI (N=41) were randomly assigned to an experimental group (n=20; mean age, 54.6±11.3y) or control group (n=21; mean age, 46.8±11.1y). The experimental group completed 10 lower extremity MLD sessions over 4 weeks and 1 educational session. The control group only attended the educational session. Outcome measures were taken at baseline (t0), at the end of 4 weeks (t1), and after 2 months for follow-up (t2). HRQOL was assessed with the Chronic Venous Insufficiency Quality of Life Questionnaire-20, symptoms (fatigue, heaviness) were assessed with a visual analog scale, severity of the disease was assessed with the Venous Clinical Severity Score (VCSS) (total score, score for each item), leg volumetry was assessed with perimeters, and plantar/dorsiflexion strength and ankle range of motion (ROM) were assessed with dynamometry. A significant interaction group×time effect was found for pain on HRQOL (F2,78=3.507; P=.035; partial η2=.087), clinical severity (F2,78=5.231; P=.007; partial η2=.118), especially for venous edema (assessed with the VCSS), fatigue (F1.67,65.21=4.690; P=.012; partial η2=.107), and heaviness (F1.57,61.32=9.702; P=.001; partial η2=.199), with the experimental group improving from t0 to t1 and t0 to t2 in all of these outcomes. No effect of MLD treatment could be found for ankle muscle strength, ankle ROM, and leg volume. Short-term MLD treatment ameliorates CVI severity and related edema, symptoms, and pain HRQOL in patients with CVI. Copyright © 2015 American Congress of Rehabilitation Medicine.

Arterial blood gases (ABGs) are often sampled incorrectly, leading to a 'mixed' or venous sample. Delays in analysis and air contamination are common. We measured the effects of these errors in patients with chronic obstructive pulmonary disease (COPD) exacerbations and controls. 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. Mean venous pH was 7.371 and arterial pH was 7.407 (p Air contamination was associated with a clinically significant increase in PO₂ in all samples, including those that were immediately analyzed. 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 PO₂, indicating that air-contaminated ABGs should be discarded. Copyright © 2010 S.

Full Text Available Background. Diabetic foot ulcers are one disabling complication of diabetes mellitus. Pirfenidone (PFD is a potent modulator of extracellular matrix. Modified diallyl disulfide oxide (M-DDO is an antimicrobial and antiseptic agent. Aim. To evaluate efficacy of topical PFD + M-DDO in a randomized, double-blind trial versus ketanserin in the treatment of noninfected chronic DFU. Methods. Patients received PFD + M-DDO or ketanserin for 6 months. Relative ulcer volume (RUV was measured every month; biopsies were taken at baseline and months 1 and 2 for histopathology and gene expression analysis for COL-1α, COL-4, KGF, VEGF, ACTA2 (α-SMA, elastin, fibronectin, TGF-β1, TGF-β3, HIF-1α, and HIF-1β. Results. Reduction of median RUV in the PFD + M-DDO group was 62%, 89.8%, and 99.7% at months 1–3 and 100% from months 4 to 6. Ketanserin reduced RUV in 38.4%, 56%, 60.8%, 94%, 94.8%, and 100% from the first to the sixth month, respectively. Healing score improved 4.5 points with PFD + M-DDO and 1.5 points with ketanserin compared to basal value. Histology analysis revealed few inflammatory cells and organized/ordered collagen fiber bundles in PFD + M-DDO. Expression of most genes was increased with PFD + M-DDO; 43.8% of ulcers were resolved using PFD + M-DDO and 23.5% with ketanserin. Conclusion. PFD + M-DDO was more effective than ketanserin in RUV reduction.

Systemic Sclerosis (Ssc) is a complex disease of the connective tissue, characterized by progressive thickening and fibrosis of the skin and the internal organs and by diffused damage of the microvascular system. The fibrosis ones of the skin associated to the characteristic vascular alterations lead to the genesis of ulcers, more or less extended, often multiple, peripheral localization, chronic course, painful, able to influence patient's quality of life. Indeed, immunity reactivity, the thinning and the loss of elasticity of the skin, the peripheral neurological damage and the eventual drug assumption that can reduce regenerative/reparative abilities, can easily make an ulcer chronic and become infected complicating still more the patient disease, rendering more difficult the cure often, ulcer evolves to gangrene, and in some cases, in amputation too. For all these reasons, we have begun to study ulcers therapy (local and systemic), considering this activity it leave integrating of the charitable distance of the sclerodermic patient, putting to point on strategy both diagnostic and therapeutic, but above all with the primary scope, if possible, is to prevent ulcers, in contrary case, to alleviate the pain and to render the quality of the life of the patient better.

Chronic venous disease (CVD) is an important clinical condition with substantial epidemiological implications and socio-economic repercussions. In the Western world the consequences of its high prevalence, the costs of diagnosis and therapy, the significant loss of working hours and the repercussions on patients'quality of life are well known. Pharmacotherapy for CVD has greatly developed over the last 40 years and largely used in the symptomatic treatment of CVD together with compression therapy and to make patients more comfortable. The clinical efficacy on the symptoms (feeling of heaviness, pain, paresthesia, heat and burning sensations, night cramps, etc.) has long been confirmed by Level III, IV and V evidence, but there are now Level I and II trials on specific drugs. For the bioflavonoids double-blind, randomised trials have used micronized purified flavonoid fraction; rutosides; escin; anthocyanosides; and synthetic calcium dobesilate. It was therefore surprising some recent difficulties in the use of this important treatment in health national system in Italy. In this up-date we use the method on evidence-based medicine from the medical literature. We have started a governance and economic analysis of the problem in Italy. Particular consideration was given to the evidence set out in review, meta-analysis, guidelines and Consensus Statements in this field. The evidence for pharmacological agents in the treatment of CVD suggests today a wide use in all CEAP classes.

Full Text Available ABSTRACT Objective: to evaluate pain in individuals with venous ulcers treated with elastic bandage and decongestant physical therapy. Methods: we studied 90 patients, divided into three groups with 30 patients each: a group treated with elastic bandage and decongestant physical therapy; a group treated with elastic bandage; and a group treated only with primary dressing according to tissue type and presence of exudate. We used the Pain Numerical Scale to quantify pain intensity and the McGill Pain Questionnaire for pain qualitative assessment. Results: in the first evaluation, all patients who participated in the study reported intense pain. In the fifth evaluation, the majority of patients treated with elastic bandaging and decongestant physical therapy did not report pain; the majority of patients in the elastic bandage group reported mild pain; and most patients treated only with primary dressing reported mild to moderate pain. During all five assessments using the McGill questionnaire, most patients in the elastic bandaging and primary dressing groups used descriptors of the sensory, affective, evaluative and miscellaneous groups to describe their pain. However, in the fourth and fifth evaluations, most patients who received decongestant physical therapy combined with elastic bandaging treatment did not use any of the descriptors. Conclusion: patients treated with decongestant physical therapy and elastic bandage presented pain improvement from the third evaluation performed on.

Marjolin's ulcers: theories, prognostic factors and their peculiarities in spina bifida patients

Full Text Available Abstract Background Due to improved care, more and more children born with spina bifida in rural Kenya are surviving into adulthood. This improved survival has led to significant challenges in their lifestyles, especially the need to ensure pressure ulcer prevention and treatment. Malignant degeneration of pressure ulcers in spina bifida patients is very rare. The author describes the clinical presentation of two pressure ulcer carcinomas that are at variance from classical descriptions. Materials and methods An internet/Medline/PubMed search of English literature for theories on Marjolin's ulcer evolution and prognostic features of Marjolin's ulcers was performed. A chart review of two young adults with spina bifida who had presented to the author's hospital between 2004 and August 2010 with chronic pressure ulcers found to be Marjolin's ulcers on histo-pathological examination was performed, and the clinical features are reported. Results The two ulcers appeared clinically benign: one was a deep ulcer, while the other was shallow; both had normal, benign-appearing edges, and a foul smelling discharge. The two ulcers were surrounded by induration and multiple communicating sinuses, with no evidence of chronic osteomyelitis. The internet search revealed a total of nine theories on Marjolin's ulcer development, as well as seven clinical and four histological prognostic features. Discussion The multifactorial theory, a coalescence of a number of proposed theories, best explains the evolution of Marjolin's ulcers. Poor prognostic features include pressure ulcer carcinomas, lesions and location in the lower limbs/trunks, all present in the two patients making their prognosis dim: this is despite the surgical margins being clear of tumor. Benign appearance, induration and presence of multiple communicating sinuses are features that have not been previously described as presenting features of pressure ulcers carcinomas. Conclusion There is need for

Ulcerative colitis is a chronic inflammatory disease, characterized by diffuse mucosal inflammation in the colon. Adalimumab, as a TNF-α blocker, offers a safe and efficacious treatment option for patients with moderate to severe ulcerative colitis and refractory or intolerant to conventional medications; however, its cost-effectiveness profile has not yet been well established. Future economic evaluations should choose appropriate comparators in the context of target-reimbursement decision making and focus on cost-effectiveness over a long time horizon.

Decubitus ulcers, also known as bedsores or pressure ulcers, affect millions of hospitalized patients each year. The microflora of chronic wounds such as ulcers most commonly exist in the biofilm phenotype and have been known to significantly impair normal healing trajectories. Bacterial tag-encoded FLX amplicon pyrosequencing (bTEFAP), a universal bacterial identification method, was used to identify bacterial populations in 49 decubitus ulcers. Diversity estimators were utilized and wound community compositions analyzed in relation to metadata such as Age, race, gender, and comorbidities. Decubitus ulcers are shown to be polymicrobial in nature with no single bacterium exclusively colonizing the wounds. The microbial community among such ulcers is highly variable. While there are between 3 and 10 primary populations in each wound there can be hundreds of different species present many of which are in trace amounts. There is no clearly significant differences in the microbial ecology of decubitus ulcer in relation to metadata except when considering diabetes. The microbial populations and composition in the decubitus ulcers of diabetics may be significantly different from the communities in non-diabetics. Based upon the continued elucidation of chronic wound bioburdens as polymicrobial infections, it is recommended that, in addition to traditional biofilm-based wound care strategies, an antimicrobial/antibiofilm treatment program can be tailored to each patient's respective wound microflora.

Full Text Available Patients with Werner’s syndrome frequently develop chronic leg ulcers that heal poorly. We present a patient who suffered from this rare syndrome and developed typical heel ulcers. Treatment of the ulcer is challenging, as flap options are limited over the lower third of the leg and skin grafting is not easy as there is a lack of healthy granulations. We successfully treated the ulcer with osteomyelitis by drilling the bone and applying an ultrathin split thickness skin graft with the thigh skin as the donor site.

Wound-related pain is often associated with skin ulcers and negatively impacts both the patient’s quality of life and, indirectly, wound healing. Pain management is an ongoing issue in the elderly, and remains underestimated and undertreated in this fragile population. Recent guidelines suggest the use of opioids as the frontline treatment of moderate and severe pain in nononcological pain in the elderly. However, due to the concerns of adverse reactions, drug interactions, and addiction, clinicians frequently hesitate to prescribe opioids. This case report describes an elderly diabetic patient with multiple ulcers of the lower limbs suffering wound-related pain. In our report, oxycodone/naloxone has proved to be an effective and safe drug, providing pain relief as well as increased compliance when redressing wounds and faster healing compared to that in similar patients. Our case provides anecdotal evidence, supported by other studies, to justify future, larger studies on chronic pain using this therapy.

Piper umbellatum L. (Piperaceae) is a shrub found in the Amazon, Savannah and Atlantic Forest region of Brazil. It is widely used in folk medicine in many countries primarily for the treatment of gastric disorders. The aim of this study was to evaluate the gastroprotective and anti-ulcer effects of hydroethanolic extract of P. umbellatum (HEPu) leaves in experimental rodents. In addition, the anti-Helicobacter pylori activity of the extract was assessed. The leaves of P. umbellatum were macerated in 75% (1:3w/v) hydroethanolic solution to obtain HEPu. The gastroprotective and ulcer healing activities of HEPu were evaluated using acidified ethanol (acute) and acetic acid (chronic) gastric ulcer models in rodents. The anti-H. pylori activity was evaluated by in vitro broth microdilution assay using H. pylori cagA + and vacA + strain. The probable mechanism of action of HEPu was evaluated by determining gastric secretory parameters, antioxidant enzyme (catalase), non-protein sulfhydryl (glutathione) and malondialdehyde levels in gastric tissue, including pro-inflammatory (IL-1β, TNF-a, IL -17, RANTES, IFN-γ and MIP-2) and anti-inflammatory (IL-10) cytokines. HEPu demonstrated potent gastroprotection against acute ulcer induced by acidified ethanol and excellent healing effect of the chronic ulcer induced by acetic acid. The gastroprotective activity in acidified ethanol is partly attributed to the antioxidant mechanisms, while anti-secretory, anti-inflammatory and regeneration of the gastric mucosa are evoked as part of its antiulcer mechanism of action. The gastric ulcer healing of HEPu also involves restoration of the altered cytokines levels to near normal. However, it has no in vitro anti-H. pylori activity. The results of this study showed that HEPu possesses preventive and curative effects in experimental models of gastric ulcers in animals. These effects are partially dependent on antioxidant, antisecretory, anti-inflammatory and mucosa regeneration. It is

Malignant degeneration in any chronic wound is termed a Marjolin's ulcer (MU). The overall metastatic rate of MU is approximately 27.5%. However, the prognosis of MU specific to pressure sores is poor, with a reported metastatic rate of 61%. This is due to insidious, asymptomatic malignant degeneration, a lack of healthcare provider awareness, and, ultimately, delayed management. An 85-year-old white male was noted by his wound-care nurse to have a rapidly developing growth on his lower back over a period of 4 months. There was history of a non-healing, progressive pressure ulcer of the lower back for the past 10 years. On examination, there was a 4 × 4 cm pressure ulcer of the lower back, with a superimposed 1.5 × 2 cm growth in the superior region. There was an absence of palpable regional lymphadenopathy. Punch biopsy revealed squamous cell carcinoma consistent with Marjolin's ulcer. The ulcer underwent excision with wide margins, and a skin graft was placed. Due to the prompt recognition of an abnormality by the patient's wound-care nurse, metastasis was not evident on imaging. There are no signs of recurrence at 1-year follow-up. Marjolin's ulcer has a rapid progression from local disease to widespread metastasis. Therefore, it is essential that wound-care providers are aware of the clinical signs and symptoms of malignant degeneration in chronic wounds.

Peptic ulcer disease is a significant cause of morbidity and mortality worldwide, with a significant burden in low- and middle-income countries. However, there is limited information regarding management of peptic ulcer disease in these countries. This study describes surgical interventions for peptic ulcer disease in sub-Saharan Africa. A systematic review was performed using PubMed, EMBASE, and African Index Medicus for studies describing surgical management of peptic ulcer disease in sub-Saharan Africa. From 55 published reports, 6594 patients underwent surgery for peptic ulcer disease. Most ulcers (86%) were duodenal with the remainder gastric (14%). Thirty-five percent of operations were performed for perforation, 7% for bleeding, 30% for obstruction, and 28% for chronic disease. Common operations included vagotomy (60%) and primary repair (31%). The overall case fatality rate for peptic ulcer disease was 5.7% and varied with indication for operation: 13.6% for perforation, 11.5% for bleeding, 0.5% for obstruction, and 0.3% for chronic disease. Peptic ulcer disease remains a significant indication for surgery in sub-Saharan Africa. Recognizing the continued role of surgery for peptic ulcer disease in sub-Saharan Africa is important for strengthening surgical training programs and optimizing allocation of resources.

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.

The paper is based on the analysis of clinical, X-ray, and morphological studies in 74 patients with massive gastrointestinal hemorrhage. The paper presents the specific features of X-ray studies of patients with bleeding gastroduodenal ulcers. X-ray studies shout be twice performed in these patients. The first study is conducted if gastroscopic findings are unclear, the repeated one is carried out while assessing changes in disease regression. X-ray diagnosis of bleeding ulcers is determined by their sites and the nature of an ulcerous process. The X-ray diagnosis of chronic callous gastric ulcers accompanied by hemorrhage was based on the detection of two direct symptoms of a niche on the gastric outlines and configuration and an inflammatory mound on the gastric outline and configuration. That of chronic bleeding ulcers of the duodenal bulb is based not only on searches niche, but other signs of the disease - the deformed organ, and the magnitude of a periprocess. 10 refs., 5 figs

Venous thrombo-embolic disease (VTE) is a potentially life threatening clinical event. Ankylosing spondylitis (AS) is a chronic inflammatory disease with a significantly increased risk of developing VTE. Management of acute proximal deep venous thrombosis (DVT) depends on the clinical status of the affected limb, extent of the thrombus and comorbidities of the patient. Semba and Dake introduced Catheter directed thrombolysis (CDT) to treat 21 patients of DVT in 1994. CDT is a life or limb sav...

Full Text Available Background/Aims: It is well established that obesity is a strongly associated risk factor for post-operative deep vein thrombosis (DVT. Physical effects and pro-thrombotic, pro-inflammatory and hypofibrinolytic effects of severe obesity may predispose to idiopathic DVT (pre-operatively because of which bariatric patients are routinely screened before surgery. The aim of this study was to audit the use of routine screening venous duplex ultrasound in morbidly obese patients before undergoing bariatric surgery. Methods: We retrospectively reviewed 180 patients who underwent bariatric surgery from August 2013 to August 2014 who had undergone pre-operative screening bilateral lower-extremity venous duplex ultrasound for DVT. Data were collected on patient's demographics, history of venous thromboembolism, prior surgeries and duplex ultrasound details of the status of the deep veins and superficial veins of the lower limbs. Results: No patients had symptoms or signs of DVT pre-operatively. No patient gave history of DVT. No patient was found to have iliac, femoral or popliteal vein thrombosis. Superficial venous disease was found in 17 (8%. One patient had a right lower limb venous ulcer. Conclusion: Thromboembolic problems in the morbidly obese before bariatric surgery are infrequent, and screening venous duplex ultrasound can be done in high-risk patients only.

A chronic ulcer with an infection such as methicillin-resistant Staphylococcus aureus is hard to heal. Plastic and reconstructive surgeons often encounter such chronic ulcers that are resistant to surgical or various conservative treatments. We applied conservative treatment using an electrolyzed strong acid aqueous solution and obtained satisfactory results. The lesion was washed with the solution or soaked in a bowl of the solution for approximately 20 min twice a day. Fresh electrolyzed strong acid aqueous solution is unstable and should be stored in a cool, dark site in a sealed bottle. It should be used within a week after it has been produced. Here we report on 15 cases of infectious ulcers that were treated by electrolyzed strong acid aqueous solution. Of these cases, 7 patients were healed, 3 were granulated, and in 5, infection subsided. In most cases the lesion became less reddish and less edematous. Discharge or foul odor from the lesion was decreased. Electrolyzed strong acid aqueous solution was especially effective for treating a chronic refractory ulcer combined with diabetes melitus or peripheral circulatory insufficiency. This clinically applied therapy of electrolyzed strong acid aqueous solution was found to be effective so that this new therapeutic technique for ulcer treatment can now be conveniently utilized.

Ninety-eight patients with esophageal cancer were treated by high dose rate intraluminal radiation therapy at the Department of Radiology of the Hyogo Medical Center for Adults between January 1982 and December 1993. Twenty patients with complete response after intraluminal radiation therapy, who were followed up with esophageal fiberscopy in our institute, were reviewed. The one-year cumulative rate of occurrence of esophageal ulcers was 81%, and in 69% of the cases the ulcers occurred from 4 to 8 months after completion of intraluminal radiation therapy. We graded esophageal ulcer by fiberscopic findings. Grade 0 was defined as no ulcer, grade 1 as superficial ulcer, grade 2 as deep ulcer, grade 3 as circumferencial ulcer, and severe stenosis. Factors related to grade were studied, and shorter distances from the source to the surface of the mucosa and lower surface doses of intraluminal radiation therapy appear to reduce the severity as graded on the above scale, of the esophageal ulcer. Four of the five 2-year recurrence-free patients suffered esophageal ulcers, which were cured from 15 to 22 months after intraluminal radiation therapy. However ulcers recurred in two patients, ong term care was thought to be necessary. (author)

Chronic venous disorders range from telangiactasia or spider veins to varicose veins, venous swellings, skin changes and venous ulcerations. The aim of this study is to assess outcome of varicose vein surgery in the ethnically diverse population of Penang, Malaysia. This study is a retrospective analysis of patients seen from 1999 to 2004. All patients who presented to the outpatient clinic of our surgical department with saphenofemoral junction (SFJ) and/or saphenopopliteal junction (SPJ) reflux associated with incompetence of the great saphenous vein (GSV) or small saphenous vein (SSV) respectively underwent classical varicose varicose vein surgery. A single surgeon at a single institution performed the surgeries. Data from pre-operative, post-operative and follow-up procedures were recorded in case report forms. A total of 202 cases were treated. Of these, 200 were qualified by the inclusion criteria and follow-ups, with 23 who were treated bilaterally. Of those treated, Chinese comprised 47.5%, Indians 27.0%, Malays 12.5% and foreigners 13.0% (largely Indonesian Chinese, British and Americans). The average age was 52.1 years. Indians had the highest average BMI of 29.2, compared to the Chinese who had the lowest of 24.6. Based on occupation, housewives (43.0%), blue collar workers (19.0%), salespersons (12.0%) and factory workers (9.5%) were among those afflicted with varicose veins. While local Chinese predominated in the business groups (salespersons and food-related workers), the Indians and Malays in this study were mainly factory workers and/or blue collar workers. Symptomatology in descending order of severity included pain in 80.0% of cases, swelling in 65.5%, heaviness in 53.5%, cramps in 53.0%, lipodermatosclerosis in 39.0%, superficial thrombophlebitis in 33.5%, venous ulceration in 32.0%, eczema 22.0% and cellulitis in 12.5% of patients. Post surgery pains dropped to 9.9%, cramps 6.4%, heaviness 5.5% and swelling 5.3% (p<0.0001 in all groups

To describe the strategies and costs associated with recruiting African American and white adults into a randomized controlled pilot trial. "Cryotherapy for Venous Disorders: A Pilot Study" is a randomized controlled trial designed to determine the effects of a cool gel wrap and leg elevation intervention versus a leg elevation alone intervention on skin temperature, skin microcirculation, quality of life, and pain in adults with stages 4 and 5 chronic venous disorders. We sought to recruit 60 participants (21 African Americans, 37 whites, and 2 Hispanic or Latino) to complete the study. These enrollment targets reflect the demographic distribution of the community in which the study was conducted (33% African American, 66% white, and 2% Latino). Proactive and reactive recruitment strategies were implemented to recruit subjects. Seventy-three individuals (9 African American men, 29 African American women, 11 white men, 22 white women, 1 Asian woman, and 1 Hispanic woman) were screened, and of those, 67 were randomized (9 African American men, 25 African American women, 9 white men, 22 white women, 1 Asian woman, and 1 Hispanic women). Fifty-eight completed the study, yielding an overall 11% attrition rate. An additional 8 subjects canceled or did not show up for a first appointment. Reactive recruitment strategies were most successful for recruiting men, women, African American, and white participants. The 3 most successful reactive strategies were referrals from providers/clinics (34%), flyers posted in the hospital elevators (22%), and targeted mailings from a business (16%). Of the healthcare provider referrals (19), wound care nurses referred 12 completed participants. The amount budgeted for advertisement was $5,000 (2% of the total grant award). The amount spent on recruitment including labor was $5,978, which averaged $103 per participant who completed the study (N = 58). Reactive strategies per participant completer proved more cost-efficient than proactive

Full Text Available Background. Chronic ulceration of the lower legs is a relatively common condition amongst adults: one that causes pain and social distress and results in considerable healthcare and personal costs. The technique of punch grafting offers an alternative approach to the treatment of ulcers of the lower limbs. Objective. Combining platelet-rich plasma and skin graft enhances the efficacy of treating chronic diabetic wounds by enhancing healing rate and decreasing recurrence rate. Platelet-rich plasma could, by stimulating dermal regeneration, increase the take rate after skin grafting or speed up reepithelialization. Methods and Materials. The ulcer was prepared by removing fibrin with a curette and the edges of the ulcer were freshened. The platelet-rich plasma has been infiltrated on the bottom and edges of the ulcer. The punch grafts were placed in 5 mm holes arranged. The ulcer was medicated with hydrogel and a pressure dressing was removed after 8 days. Results. After a few days the patient did not report more pain. Granulation tissue appeared quickly between implants. Most of the grafts were viable in 2-3 weeks. The grafts gradually came together to close the ulcer and were completed in four months.

For compensation for chronic ischemia of the pyelonephritically contracted kidney the X-ray endovascular venous revascularization was used for the first time. The surgical intervention was to stenosis the subsegmental veins of the diseased kidney resulting in recanalization of the arterial system. Outcomes of X-ray treatment were analyzed in 38 patients with chronic degree I-II renal failure and nephrogenic hypertension. In 35 (92.1 %) patients of them, there was improvement in the clinical picture of the underlying disease and in the filtrating and reabsorbing function of the kidney operated on, an increase in its sizes, and decrease in systemic blood pressure [ru

Ulcerative colitis is a chronic disease that could be triggered by acute stressful events, such as gastrointestinal infections or emotional stress. We reported the case of the onset of an ulcerative colitis after a thyrotoxicosis crisis and reviewed the literature about the relationships between thyroid dysfunctions and ulcerative colitis. A 38-year-old woman was diagnosed with ulcerative colitis after her third thyrotoxicosis crisis, two years after the diagnosis of Graves' disease. In this case, thyrotoxicosis acted as a trigger for ulcerative colitis onset. Hyperthyroidism could be a trigger able to elicit ulcerative colitis in susceptible patients.

To investigate the clinical manifestations and risk factors related to ulcer in patients with ischemic colitis (IC). Clinical data of sixty-three IC patients with definite diagnosis from June 2002 to June 2012 in the PLA General Hospital were retrospectively analyzed. All patients were classified into ulcer group (23 cases) and non-ulcer group (40 cases) according to the presence of ulcer or not. Clinical manifestations and risk factors related to ulcer lesions were compared in the two groups. Logistic regression model was used for statistical analysis. There were 50 men and 13 women enrolled, with an average age of 70 years old. The main clinical manifestations included abdominal pain [85.7% (54/63) ], diarrhea [54.0% (34/63)], hematochezia [41.3% (26/63)]. In comparison with non-ulcer group, the ulcer group showed higher incidences of chronic constipation [34.8% (8/23) vs 12.5% (5/40) , P = 0.03], enteric-coated aspirin intake [52.2% (12/23) vs 25.0% (10/40), P = 0.03] and abdomen tenderness [82.6% (19/23) vs 52.5% (21/40), P = 0.02]. Chronic constipation and enteric-coated aspirin intake were independent risk factors related to ulcer lesions (OR = 3.38, P = 0.04; OR = 5.91, P = 0.03). Patients with abdomen tenderness had higher incidence of ulcer lesion (OR = 3.12, P = 0.04). The most common location of IC was left colon [69.8% (44/63)]. No difference of site distribution was found in ulcer and non-ulcer group (P = 0.066). Splanchnic atherosclerosis in the ulcer group was more common than in non-ulcer group [88.2% (15/17) vs 58.3% (14/24), P = 0.038]. The duration of hospitalization was significantly longer in ulcer group [ (14.3 ± 7.1) d vs (6.2 ± 4.1) d, P constipation, enteric-coated aspirin intake and splanchnic atherosclerosis are risk factors related to ulcer in IC patients. Abdomen tenderness, high WBC and low Hb strongly indicate possible IC with ulcer.
