EpiDex® Swiss field trial 2004-2008

Approximately 20% of leg ulcers remain unresponsive to the best conservative standard of care. So far, these patients could either receive conventional skin grafts or had to accept their intractable wound. Skin substitutes from cell culture may represent a promising alternative to heal a major part of these patients on a non-surgical, potentially more cost-effective basis.

[Local treatment of chronic skin wounds in a Swiss out-patient wound centre 2010]

In Switzerland around 30,000 patients suffer from chronic skin wounds. Appropriate topical wound care along with treatment of the causes of the wounds enables to heal a lot of these patients and to avoid secondary disease such as infections. Thereby, the final goal of wound care is stable reepithelisation. Based on experience with chronic leg ulcers mainly in our out-patient wound centre, we give a survey of the wound dressings we actually use and discuss their wound-phase adapted application. Furthermore, we address the two tissue engineering products reimbursed in Switzerland, Apligraf and EpiDex, as well as the biological matrix product Oasis. The crucial question, which treatment options will be offered in future to the wound patients by our health regulatory and insurance systems, is open to debate.

Wegener's granulomatosis presenting as pyoderma gangrenosum

Half of the patients with Wegener's granulomatosis develop skin lesions due to the systemic vasculitis. Wegener's granulomatosis should be included in the differential diagnostic considerations for necrotic ulcers, including leg ulcers. We present a case which demonstrates the importance of histological evaluation of a skin biopsy from the margin of the ulcer for establishing the diagnosis. Antineutrophil cytoplasmic antibodies with antigen specificity for proteinase 3 (PR3-ANCA) were detected supporting the diagnosis of Wegener granulomatosis. Further evaluation showed involvement of the eyes and kidneys. The ulcer rapidly healed under treatment with cyclophosphamide and corticosteroids.

Patienters erfarenheter vid behandling av svårläkta bensår : En litteraturstudie

Introduktion: I Sverige är svårläkta bensår ett utbrett problem som ofta kräver långvarig behandling. För att behandla bensår krävs att sjuksköterskan och patient samarbetar. Syfte: Syftet med litteraturstudien var att belysa erfarenheter hos patienter som lever med behandling av svårläkta sår. Metod: Metoden som använts är en litteraturstudie vilken baseras på en sammanställning av befintlig forskning. Sökningar efter vetenskapliga artiklar gjordes i databaserna Cinahl och PubMed och resulterade i 11 artiklar vilka granskats utifrån Polit och Becks kvalitetsgranskningsmallar. Alla artiklars resultat lästes igenom flera gånger och viktiga delar ströks under och klipptes ut. De urklippta delarna skapade tre kategorier med vardera två underkategorier. Resultat: I litteraturstudien framkom att patienter ofta fokuserade mycket på hur relationen till sjuksköterskan såg ut.  Det framkom att smärta var det patienterna oftast tog upp angående sitt fysiska mående och att de upplevde att de sällan fick tillräckligt gehör från sjuksköterskan angående sin smärta. Slutsats:  De flesta patienterna uttryckte negativa erfarenheter av hur själva sårbehandlingen kändes men att en god relation till sjuksköterskan var det som kändes mest värdefullt.

Viver com úlcera crónica nos membros inferiores: análise qualitativa de narrações significativas de pessoas idosas

O envelhecimento populacional é uma realidade mundial que altera a sociedade de forma complexa, implicando a necessidade de criação de estratégias de adaptação a esta realidade. A população idosa portuguesa apresenta também um aumento exponencial, e este fenómeno está frequentemente associado à perda de capacidades e dependência e ao aumento da incidência de patologias crónicas, como por exemplo as úlceras crónicas nos membros inferiores. Esta realidade verifica-se através de uma maior procura de cuidados de saúde e também no aumento dos encargos para a família e segurança social. Assim, a aquisição de conhecimentos sobre as implicações da úlcera crónica nos membros inferiores permite, aos profissionais de saúde, melhorar a prestação de cuidados às pessoas idosas, possibilitando a gestão eficaz de recursos e a melhoria da qualidade de vida dos utentes. Neste contexto, emergiu o nosso estudo que tem como objetivo conhecer as principais implicações da presença de uma úlcera crónica, nos membros inferiores, no quotidiano de pessoas idosas. A metodologia utilizada foi qualitativa, com um tipo de estudo exploratório-descritivo, em que foram realizadas 16 entrevistas a pessoas idosas portadoras de úlcera crónica nos membros inferiores e posteriormente analisadas as narrações de vivências ou experiências significativas dos participantes, utilizando as etapas metodológicas da análise de conteúdo segundo Bardin (2011). Os resultados encontrados foram incluídos em três áreas temáticas: Sentimentos e preocupações vividos com o aparecimento e desenvolvimento da úlcera crónica, Alterações no quotidiano das pessoas idosas com úlcera crónica e a Rede de apoio da pessoa idosa com úlcera crónica. A primeira área temática demostrou que as pessoas idosas apresentam sentimentos negativos de tristeza e dor em relação às suas vivências com a úlcera crónica, e receios futuros relacionados com a incerteza da evolução da úlcera, verificando-se alguma ambivalência entre a esperança e o desespero. As alterações no quotidiano verificaram-se na mobilidade física prejudicada, na interferência em atividades de vida diária e através da necessidade de tratamento. Na mobilidade física prejudicada foi o caminhar o mais mencionado pelos participantes e na interferência em atividades de vida diária foram as atividades domésticas, sociais e de lazer. A terceira área temática incluiu a rede de apoio da pessoa idosa com úlcera crónica identificando a família, a instituição e o convivente significativo como o principal apoio dos participantes. A família apresentou um papel de destaque, através do apoio prestado pelo cônjuge e pelos filhos. A realização deste estudo proporcionou conhecer melhor a realidade das pessoas idosas com úlceras crónicas nos membros inferiores, os seus sentimentos, dificuldades e/ou incapacidades, permitindo aos profissionais de saúde aumentar os conhecimentos e elaborar estratégias para auxiliar no seu dia-a-dia, ambicionando-se uma melhoria na prestação de cuidados às pessoas idosas, famílias e sociedade.

Aspects Related to Venous Ulcer Healing and its Influence on Quality of Life

Nowadays, the varicose ulcers (VUs) are one of the most worrying leg ulcers and are an important problem in global public health, with high costs related to the treatment and its complications. Moreover, the quality of life (QOL) of the patient could be affected by pain, sleep disorders, functional impairment, depression and isolation. The VUs patient care is complex and it is necessary to know the aspects that contribute to the healing process for developing effective strategies. The members of the multidisciplinary health team should identify sociodemographic, clinical and care aspects that interfere in tissue repair and therefore impacting the QOL. Self-efficacy, adherence to treatment and self-esteem are other important aspects also related to healing and QOL, with implications for health care and the multidisciplinary team. To sum up, the use of multidisciplinary protocols allows the systematization of care for people with VUs in order to standardize therapeutic interventions with the aim to decrease the healing process time and, as a consequence, to improve the QOL.

Onychomycosis in Patients with Chronic Leg Ulcer and Toenail Abnormalities

Nails have a limited number of reactive patterns to disease. Accordingly, toenail changes of different etiologies may mimic onychomycosis. OBJECTIVE To determine the prevalence of toenail onychomycosis among patients with leg ulcer and toenail abnormalities attending a dermatology clinic. METHODS A cross-sectional study was conducted through the analysis of clinical records and results of mycological examination. RESULTS A total of 81 patients were included, with a median age of 76.0 years. Most ulcers were of venous etiology, followed by those of mixed and arterial pathogenesis. The mycological evaluation confirmed the diagnosis of onychomycosis in 27.2% of the patients. The etiologic agent was a dermatophyte in 59.1% of isolates in nail samples, while Trichophyton interdigitale was the most frequent fungal species (40.9%). CONCLUSIONS Most toenail abnormalities in patients with chronic leg ulcer were not onychomycosis. This study highlights the importance of systematic mycological examination in these patients, in order to avoid overtreatment with systemic antifungals, unnecessary costs and side effects.

Effectiveness Of 2% And 4% Papain Gels In The Healing Of Venous Ulcers

OBJECTIVE To analyze the effectiveness of 2% and 4% papain gels in tissue repair of venous ulcers. METHOD Quasi-experimental study with consecutive sample of 16 patients with 30 venous ulcers treated at the outpatient clinic of a teaching hospital, from April to November in 2011, using a form for clinical assessment of the patient and its lesion. Variables were analyzed by Wilcoxon and McNemar test (p < 0.05). RESULTS Most participants were female; aged between 51 and 59 years; obese; with hypertension. Regarding ulcers, there was an average decrease of 7.9 cm2 (50% of its original size) in 90 days; 20% of the ulcers completely healed within 56.67 days. There was an increase in epithelialization, significant reduction in the slough and edema, improved depth, in the type and amount of exudate (p < 0.0001). CONCLUSION 2% and 4% papain gels were effective in healing venous ulcers.

Métodos:o questionário foi traduzido por um tradutor profissional e por dois dermatologistas especialistas na área de úlceras venosas (UV), sendo reformulado em reunião com os três tradutores. O constructo (VLU-QoL-Br) foi submetido a pré-entrevista com 10 portadores de UV para a adaptação da linguagem. Posteriormente, foi aplicado em pacientes do HC-Unesp, e como teste-reteste para verificação de sua reprodutibilidade. Resultados:foram avaliados 82 pacientes, sendo 56 (68%) do sexo feminino. A idade média foi de 67,3 anos. O questionário foi traduzido, adaptado e aplicado aos pacientes. O constructo apresentou alta consistência interna (alfa= 0,94) e adequada correlação item-total. Quando avaliados os 32 retestes, observou-se correlação intraclasse para concordância de 0,78 (p < 0,01), indicando boa reprodutibilidade do constructo. A análise fatorial confirmatória corroborou as dimensões do questionário original: atividades, psicológico e sintomas. Escores do VLU-QoL-Br se associaram, independentemente, à área total das úlceras e a menor escolaridade dos sujeitos (p < 0,01). Conclusão:a tradução, a adaptação e a validação do questionário VLU-Qol-Br demonstrou boa performance psicométrica, permitindo seu uso clínico no Brasil. É importante avaliar seu desempenho em outras regiões e em diferentes amostras de indivíduos.

The vegetal biomembrane in the healing of chronic venous ulcers

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

Ease of Application of Medical Compression-stocking Systems for the Treatment of Venous Ulcers

OBJECTIVE: To evaluate the ease of application of two-piece, graduated, compression systems for the treatment of venous ulcers. METHODS: Four kits used to provide limb compression in the management of venous ulcers were evaluated. These have been proven to be non-inferior to various types of bandages in clinical trials. The interface pressure exerted above the ankle by the under-stocking and the complete compression system and the force required to pull the over-stocking off were assessed in vitro. Ease of application of the four kits was evaluated in four sessions by five nurses who put stockings on their own legs in a blinded manner. They expressed their assessment of the stockings using a series of visual analogue scales (VASs). RESULTS: The Sigvaris Ulcer X((R)) kit provided a mean interface pressure of 46 mmHg and required a force in the range of 60-90 N to remove it. The Mediven((R)) ulcer kit exerted the same pressure but required force in the range of 150-190 N to remove it. Two kits (SurePress((R)) Comfort and VenoTrain((R)) Ulcertec) exerted a mean pressure of only 25 mmHg and needed a force in the range of 100-160 N to remove them. Nurses judged the Ulcer X and SurePress kits easiest to apply. Application of the VenoTrain kit was found slightly more difficult. The Mediven kit was judged to be difficult to use. CONCLUSIONS: Comparison of ease of application of compression-stocking kits in normal legs revealed marked differences between them. Only one system exerted a high pressure and was easy to apply. Direct comparison of these compression kits in leg-ulcer patients is required to assess whether our laboratory findings correlate with patient compliance and ulcer healing.

Subjective Aspects of People with Chronic Ulcers: a Qualitative Study in Brazil and Portugal

Introduction: The experience built in the process of living with chronic ulcer is marked by changes such as the inability to work, to relate socially and causes the need to adapt to a routine care. Understanding this network of meanings is important to develop techniques of individual or collective care. Objective: To understand impregnated subjectivities in the everyday experiences of Brazilian and Portuguese patients with chronic ulcers, in the light of the Oral History of life. Method: Comparative study with a qualitative approach, using Oral History as method and technique. The network of collaborators, formed by males and females, aged 39-82 years, was structured into two groups, one consisting of 06 people in Natal/RN, Brazil and another composed of 10 people in Évora/Portugal. In both groups, the narratives were collected through open questions, which were recorded, transcribed and analyzed by the technique of thematic content analysis. Results: Through the analysis, three themes were revealed: Social repercussion in Brazil and in Portugal; Trajectory of theinjured person; and Coping mechanisms. Conclusion: Changes were observed in social life, leading contributors to isolation, in addition to confronting the stigma experienced. There were also identified points as the reinterpretation of chronic wound carrier about their disease and coping strategies of their chroniccondition.

Quality of life in people with leg ulcer, integrative review

Objective: To identify the main changes in the daily life of people with leg ulcer and how that affects the person’s life’s quality. Methodology: We used the methodology PI [C] OD and were selected four research articles, taken from EBSCO, PubMed, and EWMA. Results: The main changes identified in the people’s daily live with leg’s ulcers are physical (pain, decreased mobility, presence of exudate, bad smell from the wound and change in the style of clothing), psychological (sleep disorders, depression, anxiety, feelings of rejection and low self-esteem), social (isolation, restriction in leisure activities, inability to perform household chores). Conclusions: The literature about person’s life’s quality with leg ulcer reported a significant impact in the daily life of that person. The care provided by nurses should be centred on the person itself, integrating all the kind of needs and the leg ulcer mustn’t be the sole focus of care.

Phototherapy Improves Healing of Chronic Venous Ulcers

Objective: We tested the hypothesis that LED phototherapy with combined 660-nm and 890-nm light will promote healing of venous ulcers that failed to respond to other forms of treatment. Background Data: A variety of dressings, growth factors, and adjunct therapies are used to treat venous ulcers, but none seems to yield satisfactory results. Materials and Methods: We used a randomized placebo-controlled double-blind study to compare a total of 20 patients divided with 32 chronic ulcers into three groups. In group 1 the ulcers were cleaned, dressed with 1% silver sulfadiazine (SDZ) cream, and treated with placebo phototherapy (<.03 J/cm(-3)) using a Dynatron Solaris 705 phototherapy research device. In group 2 the ulcers were treated similarly but received real phototherapy (3 J/cm(-2)) instead of placebo. In group 3 (controls), the ulcers were simply cleaned and dressed with SDZ without phototherapy. The ulcers were evaluated with digital photography and computer image analysis over 90 d or until full healing was attained. Results: Ulcers treated with phototherapy healed significantly faster than controls when compared at day 30 (p < 0.01), day 60 (p < 0.05), and day 90 (p < 0.001), and similarly healed faster than the placebo-treated ulcers at days 30 and 90 (p < 0.01), but not at day 60. The beneficial effect of phototherapy was more pronounced when the confounding effect of small-sized ulcers was removed from the analysis. Medium- and large-sized ulcers healed significantly faster with treatment (>= 40% rate of healing per month) than placebo or control ulcers (p < 0.05). Conclusion: Phototherapy promotes healing of chronic venous ulcers, particularly large recalcitrant ulcers that do not respond to conventional treatment.

Incidence of Pressure Ulcers in the Institutionalized Elderly

PURPOSE: The aim of this study was to analyze the incidence of pressure ulcers (PUs) in elderly people living in long-term care facilities (LTCFs). DESIGN: We completed a prospective, comparison cohort study. SUBJECTS AND SETTING: Ninety-four persons, 60 years or older, participated in the study. Participants resided in 4 not-for-profit LTCFs in 3 cities in the southern region of the Brazilian state of Minas Gerais. METHODS: Participants underwent complete skin examination and Braden Scale rating every 2 days for 3 months. When a PU was detected, a careful examination was done to assess its stage, location, and size. From this moment on, the patient was included in the incidence rate and was excluded from the study. RESULTS: The incidence rate of PUs was 39.4%; 37 (77.1%) developed a single ulcer. The most common locations were the malleolus (27.1%) and the ischium (25.0%). Stage I PU were most frequent (66.7%). Females (62.8%) and whites (68.19%) prevailed, with an average age of 79.06 +/- 9.6 years. Body mass index was 20.93 +/- 4.9, with a predominance of urinary diseases (58.5%) and use of neuroleptics/psychotropics (52.1%); 28.7% had had a previous ulcer. Gender and the occurrence of a previous ulcer were found to predict the development of PU, based on logistic regression analysis (r(2) = 0.311). CONCLUSIONS: The overall incidence of PU was significant, but the incidence of stage II and higher PUs was less than 12% and no elders had stage III or IV ulcers. Factors associated with PU development include female gender, regular use of neuroleptic or psychotropic medications, and a history of pressure ulceration.
