    Leg ulcer is a leading cause of morbidity among older subjects, especially women in the Western world. About 400 years BC, Hippocrates wrote, "In case of an ulcer, it is not expedient to stand, especially if the ulcer be situated on the leg". Hippocrates himself had a leg ulcer. The best treatment of any leg ulcer depends upon the accurate diagnosis and the underlying aetiology. The majority of leg ulcers are due to venous disease and/or arterial disease, but the treatment of the underlying cause is far more important than the choice of dressing. The aetiology, pathogenesis, treatment, and the future trends in the management of the leg ulcers are discussed in this review.

    The most frequent causes of leg ulcers include venous incompetency (superficial and deep), arterial insufficiency, trauma, vasculitis, and neoplasm. Leg ulcers from injury by stingrays are quite rare. In this case report, we describe a leg ulcer caused by a stingray sting complicated by infection, which healed completely without surgery. In addition, since there few cases in the literature describing such traumas, we performed a comprehensive review of the literature. Important is the fact that the wound healing was complete without resorting to surgery, but only with a correct targeted antibiotic therapy and the use of a collagenase, which has the particularity of having hyaluronic acid as a component.

    Major hemoglobinopathies, including sickle cell anemia, are becoming a global health issue. Leg ulcers are the most common cutaneous manifestation of sickle cell disease and an important contributor to morbidity burden in this population. Leg ulcers following sickling disorders are extremely painful, and hard to heal. The clinical evidence for the optimal management of these ulcers is limited. Treating the cause and the strategies to prevent sickling are the mainstay of treatment. The basic principles of wound bed preparation and compression therapy is beneficial in these patients.

    Lower leg ulcers is the most common form of ulceration of the lower extremities. The prevalence of leg ulcer varies among studies from 0.1% to 0.6%. In the majority of studies, 1% of the population develop leg ulcer at least once in lifetime. The prevalence is higher in elderly people. There are several hypotheses used to explain the pathophysiological steps leading from the popliteal venous hypertension in value. Currently, the treatment of leg ulcer relies on due knowledge of ulcer pathophysiology and making an accurate diagnosis. Venous disease has a significant impact on quality of life and work productivity. In addition, costs associated with the prevention and treatment of lower leg ulcers are significant.

  6. Venous leg ulcers

    2011-01-01

    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 advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 101 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. 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

    2013-01-01

    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. PMID:24198978

    Ischemic ulcers of the leg having characteristics different from those of ordinary leg ulcers have been observed in a small number of hypertensive patients, mostly women, during the past few years. Such ulcers are usually located above the ankle. They begin with a small area of purplish discoloration at the site of slight trauma, and progress to acutely tender ulceration. In studies of tissue removed from the margin and the base of an ulcer of this kind, obliterative arteriolar sclerotic changes, ischemic-appearing connective tissue and inflammatory changes were noted. Two additional cases are reported. ImagesFigure 1.Figure 2.Figure 3.Figure 4. PMID:15398887

    2015-01-01

    Venous leg ulcers, the most common form of leg ulcers, are relevant to the pathogenicity of pericapillary fibrin cuff. Sarcoidosis, a multiorgan granulomatous disease, causes fibrin deposition in tissues. We report a case of a 50-year-old man with venous leg ulcers coexisting with sarcoidosis. On the basis of the histologic findings, we propose the hypothesis that sarcoidosis patients are prone to the development of venous leg ulcers. PMID:26719645

    We report a case of spondylodiscitis due to Streptococcus dysgalactiae subsp. equisimilis spreading from infected leg ulcers. The route of infection could be unequivocally demonstrated by culturing identical isolates from leg wounds, blood culture and intra-surgery specimens from the spine. The present case illustrates the pathogenic potential of group G streptococci also for non-diabetic adults.

    Compression therapy is well-tried treatment with only few side effects for most patients with leg ulcers and/or edema. Despite the very long tradition in German-speaking countries and good evidence for compression therapy in different indications, recent scientific findings indicate that the current situation in Germany is unsatisfactory. Today, compression therapy can be performed with very different materials and systems. In addition to the traditional bandaging with Unna Boot, short-stretch, long-stretch, or multicomponent bandage systems, medical compression ulcer stockings are available. Other very effective but far less common alternatives are velcro wrap systems. When planning compression therapy, it is also important to consider donning devices with the patient. In addition to compression therapy, intermittent pneumatic compression therapy can be used. Through these various treatment options, it is now possible to develop an individually accepted, geared to the needs of the patients, and functional therapy strategy for nearly all patients with leg ulcers.

  14. Pharmacologic treatment of venous leg ulcers.

    PubMed

    Dormandy, J A

    1995-01-01

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

  15. Ulcerated necrobiosis lipoidica as a rare cause for chronic leg ulcers: case report series of ten patients.

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

    Hydroxyurea is a cytostatic agent that has recently become the drug of choice in the treatment of various myeloproliferative diseases. The cutaneous side effects of hydroxyurea include xerosis, hyperpigmentation, nail discoloration, and scaling. Leg ulcers have only rarely been reported in association with hydroxyurea treatment. A 75-year-old woman presented with leg ulcers, nail discoloration, and xerosis. The leg ulcers were refractory to conventional treatment. She had been taking oral hydroxyurea since being diagnosed with essential thrombocytosis in 2002. Hence, we suspected hydroxyurea-induced leg ulcers and discontinued her hydroxyurea treatment; the ulcers gradually healed thereafter. We present a rare case of hydroxyurea-induced leg ulcers in Korea. PMID:20548853

    The prevalence of leg ulcers, which are most commonly caused by venous insufficiency, is high in Europe. Current treatments are fairly unsatisfactory, with long healing times in many cases, as well as a high risk of relapse. Over the last 15 years, improved understanding of the cellular and molecular mechanisms at work in delayed wound healing has contributed to the development of cellular therapy in this field. The use of keratinocytes or cultured fibroblasts, whether autogenic or allogenic, has been of little value in terms of either healing times or rates of complete healing. For the moment, there are very few allogenic skin substitutes available; they are expensive and have been insufficiently studied in the indication of leg ulcers. Pluripotent mesenchymal adult stem cells have proved capable of accelerating wound healing in animal models and their study in chronic wounds in humans is currently awaited.

  18. Optimal management of chronic leg ulcers in the elderly.

    1997-05-01

    Chronic leg ulceration is a very common clinical problem in the elderly. Good management depends entirely on making an accurate diagnosis, and planning treatment after considering all aspects of patient well-being. All elderly patients with leg ulcers benefit from an assessment of their vascular status, since the effects of gravity influence treatment and healing irrespective of the diagnosis. The most common causes of ulceration are venous and arterial disease. Diabetes mellitus, pressure, vasculitis, metabolic abnormalities and skin cancer are all unusual causes of leg ulceration, but must be considered in the differential diagnosis. Almost all patients with ulcerated legs benefit from the use of compression bandaging at a level appropriate to their vascular status. In patients with venous ulcers, this can be achieved with a number of bandaging techniques; however, multilayer bandaging appears to be the most cost-effective means available, particularly when combined with community-based leg ulcer clinics. The effects of oral drug therapy for venous and arterial disease have been disappointing. Local dressings are important in ulcers that are not suitable for compression therapy. The choice of dressing depends on the nature of the ulcer and the tolerability of the dressing for the patient.

    The ulcers, located below the knees and remaining for 6 weeks and more, are called trophic leg ulcers. The leg ulcers of different etiology disable 0.8-1% of total Earth population. It was found that blood vessel problems in legs account for more than 80% of ulcers; even 65% from these are caused by venous diseases. In Lithuania about 8000 patients suffer from venous trophic ulcers. Regardless of modern methods the treatment of leg ulcers remains an extremely expensive process. The treatment cost of trophic ulcers is the highest of all surgical wounds and also requires a lot of personal investments. In order to assess the efficiency of autodermoplastics in the treatment of large venous ulcers in legs a prospective study was carried out of 111 patients who were treated in the Department of Plastic Surgery and Burns of Kaunas University of Medicine Hospital from January 2001 to January 2004. The data was analyzed exceptionally of the operated 54 patients with venous origin ulcers open for more 6 months or exceeding 50 cm2. The above-mentioned patients were prepared for surgery by dressing the wounds with hydrocolloid Granuflex bandages and were operated by transplanting a 0.2-0.3 mm thick skin graft. The results were estimated by the surgeon during the dressings after the operation. The graft was taken in 35 (64.81%) cases; in 19 (35.19%) cases the graft was partially not taken and there were no cases when it was not taken at all. We came to the conclusions that skin graft transplantation is efficient in treatment of trophic venous leg ulcers larger than 50 cm2 and cures the trophic leg ulcers of vein origin completely in 2-3 weeks for 64.81% patients.

    We present a man with refractory leg ulcers, bilateral varicosis of the lower extremities, and Buerger disease. Autoimmune work-up was negative. However, chromosome analysis showed Klinefelter syndrome (48 XXY). Ulcerative lesions of the lower extremities are a complication of Klinefelter syndrome. To date, the pathogenesis of ulcers in Klinefelter syndrome has not been clarified, but several factors, such as abnormalities of fibrinolysis and prothrombotic states, might be involved. Our present case emphasizes the importance of considering Klinefelter syndrome in the differential diagnosis of a male patient with nonhealing ulcers of the lower extremities.

    Pyoderma vegetans is a rare disorder that more commonly affects middle-aged persons, with a male predilection. It is characterized by vegetating lesions that coalescence into a plaque with eroded surface, covered by purulent discharge and crusts. The etiology of this disease is not known with certainty, but it is often associated with bacterial infections in immunocompromised patients. We report the case of a 73-year-old men who presented to the Iasi Dermatology Clinic with a large, irregular, relatively well-defined dermohypodermic ulcer, with infiltrated sclerosing borders, accompanied by pain, with the floor covered in the Northern part by a proliferative, vegetative bleeding area, and the rest by a yellowish secretion and cellular debris, located on the left leg. Bacteriological examination of ulcer secretion identified Pseudomonas aeruginosa. Anatomopathological examination confirmed the development of Pyoderma vegetans on chronic leg ulcer. Under specific treatment for chronic leg ulcer and eradication of infectious focus the outcome was favorable both in terms of trophic ulcer scar- ring and Pyoderma vegetans healing.

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

    In Brazil, leprosy is a widespread infectious and contagious disease. Clinicians and specialists view leprosy broadly as a systemic infection, since, in its manifestations, it mimics many conditions, such as rheumatic, vascular, ENT, neurological and dermatological diseases. There are few studies that characterize the factors associated with ulcers in leprosy. These injuries should be prevented and treated promptly to avoid serious problems like secondary infections, sepsis, carcinomatous degeneration and amputations. We describe a patient with ulcers on his legs, involving late diagnosis of lepromatous leprosy. PMID:27828650

    1999-11-01

    Venous ulcers are still today one of the main socioeconomic problems of medical interest in terms of prevalence, morbidity, and costs to the health service. In the past, various studies have been carried out to identify a systemic pharmacologic treatment able to accelerate venous ulcer healing times, but frequently the results have not been satisfactory. The aim of this study was to evaluate the efficacy of sulodexide, a drug with profibrinolytic and antithrombotic activity, in accelerating venous ulcer's healing time. Ninety-four patients (32 men and 62 women), aged 72 years old on average, were randomly distributed between two groups. In the first group ("control group") a standard treatment was applied, which consisted of cleansing by washing with physiological solution and the application of elastic compression with short-extensibility, removable bandages. The second group ("sulodexide group") received the standard treatment plus sulodexide (600 lipoprotein lipase releasing units [LRU] by im route per day for 30 consecutive days, followed by 500 LRU by oral route per day for a further 30 days). After 2 months the venous ulcers were found healed in 15 patients (36%) in the control group and in 30 patients (58%) in the sulodexide group (p = 0.03). The life table showed that the healing times were shorter in the sulodexide group in the first 2 months of treatment. Total healing times amounted to 110 days in the control group and 72 days in the sulodexide group (p = 0.08) and the results were in proportion to the initial severity of the lesion. A significant correlation was noted between ulcer healing times and severity of the initial ulcerous lesion, the duration of the ulcer, and the group the patient belonged to. No correlation was found between age, gender of the patient and the etiology of the ulcer. In conclusion sulodexide was shown effective in the treatment of venous leg ulcers, yielding healing more quickly than the standard treatment.

    PubMed

    Maillard, H

    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.

    A 58-year-old black man with leg ulcers of 43 years duration responded to pentoxifylline 400 mg tid in 8 months. The ability of pentoxifylline to increase erythrocyte flexibility and decrease blood viscosity was the basis for our use of this agent. Oral pentoxifylline may be a useful adjunct in healing sickle cell leg ulcers and preventing their recurrence.

    Leg ulcers are common and costly to treat, and the quality of care provided to patients with this condition varies widely across the UK. The introduction of specialized community-based leg ulcer clinics in Gloucestershire has been associated with increased ulcer healing rates and decreased rates of ulcer recurrence, but this model of care has not been widely replicated. One way of ending this 'postcode lottery' is to produce a National Service Framework for leg ulcers, with the aim of delivering high-quality evidence-based care via such clinics under the supervision of local consultant vascular surgeons. Existing National Service Frameworks cover a range of common conditions that are, like leg ulceration, associated with significant morbidity, disability and resource use. These documents aim to raise quality and decrease regional variations in health care across the National Health Service, and leg ulceration fulfils all the necessary criteria for inclusion in a National Service Framework. Centrally defined standards of care for patients with leg ulceration, and the reorganization and restructuring of local services to allow the accurate assessment and treatment of such patients are required. Without a National Service Framework to drive up the quality of care across the country, the treatment of patients with leg ulcers will remain suboptimal for the majority of those who suffer from this common and debilitating condition.

    The management of yaws has changed in recent years. Mass treatment with oral azithromycin has replaced intramuscular benzathine benzylpenicillin. Treponemal and non-treponemal serology (equivalent to TPHA and RPR) point-of-care blood testing is now available. In addition, recent studies in yaws endemic regions have shown that a significant number of leg ulcers in children which are clinically suggestive of yaws are caused by Haemophilus ducreyi. It is noteworthy that the World Health Organization has also set the ambitious goal to eliminate yaws by 2020.

    Summary Background Large leg ulcers (LLU) may complicate autoimmune diseases. They pose a therapeutic challenge and are often resistant to treatment. To report three cases of autoimmune diseases complicated with LLU. Case Report Case 1. A 55-year old woman presented with long-standing painful LLU due to mixed connective tissue disease (MCTD). Biopsy from the ulcer edge showed small vessel vasculitis. IV methylprednisolone (MethP) 1 G/day, prednisolone (PR) 1mg/kg, monthly IV cyclophosphamide (CYC), cyclosporine (CyA) 100mg/day, IVIG 125G, ciprofloxacin+IV Iloprost+enoxaparin+aspirin (AAVAA), hyperbaric oxygen therapy (HO), maggot debridement and autologous skin transplantation were performed and the LLU healed. Case 2. A 45-year old women with MCTD developed multiple LLU’s with non-specific inflammation by biopsy. MethP, PR, hydroxychloroquine (HCQ), azathioprine (AZA), CYC, IVIG, AAVAA failed. Treatment for underlying the LLU tibial osteomyelitis and addition of CyA was followed by the LLU healing. Case 3. A 20-year-old man with history of polyarteritis nodosa (PAN) developed painful LLU’s due to small vessel vasculitis (biopsy). MethP, PR 1 mg/kg, CYC, CyA 100 mg/d, AAVAA failed. MRSA sepsis and relapse of systemic PAN developed. IV vancomycin, followed by ciprofloxacin, monthly IVIG (150 g/for 5 days) and infliximab (5 mg/kg) were instituted and the LLU’s healed. Conclusions LLU are extremely resistant to therapy. Combined use of multiple medications and services are needed for healing of LLU due to autoimmune diseases. PMID:21169912

    The present status of clinical leg ulcer healing research was reviewed by 25 experts over 2 days on September 28 and 29, 2015. Multiple clinical effectiveness reviews were presented suggesting that published clinical wound healing research often does not meet present (2015) evidence based standards. Specific areas requiring remediation were highlighted and approaches to overcoming existing challenges were proposed. Participants using anonymous voting technology developed an action plan to resolve perceived deficiencies. Statements were accepted if 75% of participants agreed. Older patients with a high frequency of comorbid conditions posed particular difficulties in designing clinical research protocols and better diagnostic categorization is necessary A standardized model template for collecting information about diagnosis and evaluation of the effect of interventions on healing of all types of leg ulcers was considered a high priority. Such a model template could be modified depending on the specific etiology of the leg ulcers. Generally agreed on quantifiable standards to establish degree of morbidity was considered a high priority. There was universal agreement that sources of funding and conflicts of interest needed to be disclosed in presentations and all publications. All clinical research studies should be registered with appropriate authorities. There was substantial enthusiasm for a clinical research network with quality standards for membership and an advisory research core available to investigators. Such a network should be funded and actively managed to insure long-term viability. The governance of such an entity needs to be established by the wound care community. The present trend to integrate patients into the clinical research process was endorsed and there was enthusiasm to develop patient advocacy for wound healing research.

    Chronic vascular wounds are often painful. Pain can develop whatever the cause of the ulceration. It is well known during wound care but can occur at any time. The pain is often a complex phenomenon involving nociceptive pain, neuropathic pain, anxiety and emotional suffering, all directly related to the chronic disease. Care for the patient suffering from pain must take into consideration all of these aspects of the disease. The therapeutic strategy should rely on the use of different pharmacological agents, well-adapted local care using the different available analgesic tools and include psycho-affective care.

  14. Ulcer pain in patients with venous leg ulcers related to antibiotic treatment and compression therapy.

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

    PubMed

    2010-03-01

    Leg ulcers are a frequent and serious complication of polycythemia vera (PV). They are caused by a synergic action of vascular, neurological and infectious physiopathologic mechanisms. Furthermore, cytostatic therapies commonly employed to control the myeloproliferative disease negatively interfere on the development of granulation tissue, slowing down the recovery of the ulcer. We describe the case of a 70 years old woman with PV, who had calcaneous and perimalleolar ulcers. They were so painful that they made it almost impossible for her to sleep and walk normally. These ulcers were particularly resistant to common topical therapy. Further and accurate investigations showed that these ulcers were a complication of hydroxycarbamide therapy employed and they were not a complication of the ematologic disease. Leg ulcers during hydroxycarbamide therapy are a relatively frequent but underestimated condition. Pathogenesis is bound to numerous factors, i.o. cellular damage and tissutal hypoxia, consequent of drug induced macroerythrosis. In our patient drug substitution and prosecution of topic therapies allowed the recovery of the leg ulcers, particularly serious for both, extensiveness and symptoms.

  17. Pentoxifylline in the treatment of venous leg ulcers.

    A double-blind, placebo-controlled study was carried out in 12 patients suffering from chronic venous insufficiency and persistent leg ulcers to assess the efficacy of pentoxifylline treatment as an adjunct to compression bandaging in the conservative management of venous leg ulcers. Six patients were allocated at random to receive twice-daily infusions of 200 mg pentoxifylline intravenously and 400 mg pentoxifylline orally 3-times daily for 7 days then 400 mg oral doses 3-times daily for a further 60 days. The control group received matching placebo in an identical regimen. Treatment outcome was assessed by changes between the start and end of the study in venous ulcer surface area, and continuous wave Doppler ultrasound was used to monitor ankle/arm systolic pressure ratio, venous pressure at the ankle, valvular competence and possible venous reflux at intervals throughout the study period. The results showed that in the patients treated with pentoxifylline complete ulcer healing took place in 4 out of 6 and there was a significant reduction in mean ulcer surface area. In the control group, complete ulcer healing was recorded in 1 out of 6 patient only and the ulcer area was only moderately reduced in the others. There was no statistically significant differences between the two groups in the variables monitored by Doppler ultrasound but the difference between treatment outcome was significant. Treatment was well-tolerated.

    Venous leg ulcer pain experienced during compression bandaging is poorly understood. A prospective, pilot cohort study was initiated to determine the feasibility of conducting a large-scale, repeated measures cohort study of venous leg ulcer pain and to document and describe the venous leg ulcer pain experience during the first 5 weeks of treatment with compression bandages. Eligible individuals admitted to a nurse-led community leg ulcer service in one Canadian community were recruited for the 5-week study. Pain assessment tools (ie, numerical rating scale and short form McGill Pain Questionnaire) were evaluated by 20 venous ulcer patients (mean age = 73.7 years) and their nurses for ease of use during one baseline and five weekly follow-up visits. Health-related quality of life (HRQL) information was obtained. Nurses reported on ease of integrating pain data collection into regular clinical care. Each pain assessment tool was audited for completion. Most participants found the pain assessment tools easy to use, but nurses reported lengthened visit times with some participants as a result of tool administration difficulties, particularly the visual analogue scale (VAS). Overall completeness of pain assessment tools ranged from 85.0% (visual analogue scale) to 96.3% (present pain intensity and word descriptor list). The vast majority of patients (18) reported ulcer pain at baseline. Total mean scores for all pain assessment tools used decreased over time, but most patients reported pain throughout the study. The most common pain descriptors used were "aching," "stabbing," "sharp," "tender," and "tiring." Health-related quality of life was low and did not change during the 5-week study. The results of this study suggest that the vast majority of venous ulcer patients experience pain and that it is feasible to examine this pain in individuals receiving care in the community over time.

    Increasing demand for services and rising costs in the NHS have resulted in reduced consultation times and resources for clinicians when treating patients with compression therapy. This article emphasises the importance of considering alternative treatment approaches, while encouraging patient choice, independence and self-care. One alternative treatment is the use of compression hosiery kits for the management of venous leg ulceration and oedema.

    Compression therapy, together with modern moist wound treatment, is the basis for a successful conservative treatment of patients with chronic leg ulcers. In clinical practice, it is often the patients themselves who apply compression therapies. Many of the mostly elderly patients, however, are not able to reach their legs and feet due to movement restrictions, such as arthritis, arthrosis and even obesity. An adequate compression therapy also requires extensive experience and regular training. In practice only the minority of patients can perform bandaging well and therefore this should not be recommended. Self-management with do-it-yourself medical devices will become more and more important in the future. In addition to the psychological factors, cost aspects and demographic change, an expected lack of qualified nursing staff due to the number of elderly patients who are potentially in need of care means that self-management is becoming increasingly more important. For the essentially important compression therapy of patients with chronic leg ulcers, there already exist various therapy options. The needs, preferences and abilities of the patients concerned can be considered when selecting the appropriate system. Particularly for the self-management of compression therapy, adaptive compression bandages are suitable for patients with leg ulcers during the initial decompression phase and ulcer stocking systems in the subsequent maintenance phase.

    2013-01-01

    An investigation of effectiveness of topical treatment of nonhealing chronic venous leg ulcers with propolis ointment was conducted. 56 patients were included in the study and randomized into two groups. In group 1, there were 28 patients (ulceration area: 6.9–9.78 cm2) treated by means of topical propolis ointment application and short stretch bandage compression. In group 2, there were 29 patients (ulceration area: 7.2–9.4 cm2) treated by means of Unna boot leg compression without topical propolis treatment. In the study, the efficacy of both treatment methods in patients with resistive venous leg ulcers was compared. The ulceration of patients from group 1 healed completely after 6 weeks of therapy in all cases. In all patients from group 2, the process of healing was longer but successfully completed after 16 weeks of the therapy. We found that an adjunctive propolis ointment treatment increases the efficacy of the short stretch bandage compression stocking, and this combined treatment is more effective than Unna's boot compression alone.

    2017-03-01

    The authors report a case of pretibial myxedema (PTM) masquerading as a venous leg ulcer to alert wound care clinicians to this diagnostic possibility. Pretibial myxedema is a localized form of mucin cutaneous deposition characterized by indurated plaques most commonly on anterior legs. It is more likely to present in patients with Graves' disease, but it can be found in euthyroid patients as well. The physiopathology of PTM is complex, and there is an accumulation of highly hydrophilic glycosaminoglycans in the dermis. Minimal morbidity is associated with PTM, but the pruritus related to mucin deposition can be intense. The skin around venous leg ulcers and the skin changes related to PTM can have a similar clinical presentation, which may be a reason PTM is under-recognized.

  4. Pentoxifylline as adjunctive therapy in leg ulcer management.

    PubMed

    Brenman, S A

    1991-07-01

    Refractory or recurring leg ulcers typically signify the presence of impaired venous or arterial microcirculation (or both). A current hypothesis suggests that local oxygen and nutrient deficits occur because capillary lumens narrow and become permeable to fibrinogen and proteins by activated white blood cells and inadequate fibrinolysis. As a result, the deposition of a relatively impermeable perivascular fibrin sheath occurs, preventing adequate delivery of oxygen and nutrients. Therapy should therefore aim at reversing these deficits and improving wound healing. Pentoxifylline (Trental), used in combination with local wound care and appropriate antibiotic therapy, has been successful in significantly improving the healing of refractory leg ulcers. Pentoxifylline can reverse the abnormal function of white and red blood cells and platelets, as well as reduce blood viscosity and vascular permeability. The mechanisms of action of pentoxifylline are described in light of current hypotheses pertaining to leg ulcer development. Also discussed are nine cases in which pentoxifylline, when added to previously unsuccessful local wound care, either improved or healed the refractory ulcers.

    Low energy laser therapy (LELT) was used to treat chronic leg ulcers. Seven patients, aged 59 to 96 years, with 11 leg ulcers were referred for laser therapy by plastic surgeons. They had a history of ulceration of 3 - 50 years and five of the patients had breakdown of previous skin grafts. Laser treatments were administered with a microprocessor-controlled device. A 22 red ((lambda) equals 660 nm) laser head was utilized to provide a dose of (4 - 6) J/cm2 and 7 infrared ((lambda) equals 880 nm) head to provide a dose of (4 - 8) J/cm2. The patients were treated three to five times per week, 25 - 30 treatments per course. Three patients underwent two courses of laser therapy with three weeks interval between them. All patients, after 5 - 10 laser treatments, have gotten relief of pain and decreased the amount of analgesics used. All ulcers in six patients were completely healed and two ulcers in the seventh patient decreased in size by 75%. One may conclude the developed laser methodology might be used as a preventative measure to avoid plastic surgery or improve its success.

  6. Chronic leg ulceration in the community: changing the focus.

    PubMed

    Brown, Annemarie

    2010-09-01

    Compression therapy is considered the gold standard for healing chronic venous leg ulceration, and impressive healing rates are achievable for many patients. Unfortunately, this condition is chronic, characterized by frequent recurrences and, for some patients, ulcer healing may never occur. Within community services, commissioners of nursing services tend to focus on complete ulcer healing within a defined timescale as quality indicators. The challenge, therefore, will be for community nurses to demonstrate alternative but equally effective patient-centred outcome measures for nursing interventions when healing is delayed or does not occur. The current government health policy encourages active patient involvement in treatment, with an emphasis on self-care/management for patients with chronic conditions. Self-management interventions, such as the Expert Patient Programme (Department of Health, 2001) for chronic conditions, have been positively evaluated and have demonstrated considerable benefits for patients in terms of pain reduction and improved psychosocial wellbeing. This article briefly discusses the outcomes of such interventions and suggests that nurse-led self-care programmes could be adapted for leg ulcer patients in order to provide alternative outcome measures for nursing interventions when ulcer healing may not be achievable. This article also gives an overview of current innovations developed to encourage patient involvement and self-care in this client group.

    Background A systematic review was conducted to analyse journal articles that describe or measure the impact of leg ulceration on patients' quality of life (QoL) in order to improve the content of an educational programme that aims to enhance self-care agency in leg ulcer patients. Method Original articles published in English and German between 1990 and 2006 were included if the findings were analysed at the level of patients. Articles were excluded if (1) they investigated the impact of specific treatments or settings on QoL or (2) focused mainly on arterial ulcers or diabetic foot ulcers. Results Twenty-four original research articles met the inclusion criteria; 11 studies used a quantitative, 11 studies a qualitative, and 2 used a mixed method approach. The findings were collapsed into 5 core domains. Quantitative studies commonly investigated the parameters of pain, sleep, social isolation, and physical mobility. Patients had significantly more pain, more restrictions regarding social functioning, less vitality, and limitations with respect to emotional roles compared to the respective controls. Other problem areas identified were restrictions in work capacity, recreation, social interaction, psychological well-being, as well as problems caused by treatment regimes. Inconclusive results were obtained regarding pain intensity, physical restrictions, and gender effects. Limitations Numerous original studies neither undertook a differentiation of participants by ulcer aetiology nor did they analyse the results according to gender differences. Conclusion As leg ulceration has an impact on QoL, national guidelines on the treatment of leg ulceration need to more specifically address these far-ranging effects identified in this review.

    2016-02-01

    Venous leg ulcers are the most common cause of chronic leg wounds, accounting for up to 70 % of all chronic leg ulcers and carrying with them a significant morbidity, especially for elderly patients. Among people aged 65 years and older, the annual prevalence is 1.7 %. Billions of dollars per year are spent caring for patients with these often difficult-to-heal and sometimes recurrent chronic wounds. Chronic non-healing wounds of the lower extremities are susceptible to microbial invasion and can lead to serious complications, such as delayed healing, cellulitis, enlargement of wound size, debilitating pain, and deeper wound infections causing systemic illness. Recognition and treatment of the infected venous leg ulcer is an essential skill set for any physician caring for geriatric patients. Most physicians rely on subjective clinical signs and patient-reported symptoms in the evaluation of infected chronic wounds. The conventional bacterial culture is a widely available tool for the diagnosis of bacterial infection but can have limitations. Systemic antibiotics, as well as topical antiseptics and antibiotics, can be employed to treat and control infection and critical colonization. Better understanding of microbial biofilms in the wound environment have caused them to emerge as an important reason for non-healing and infection due to their increased resistance to antimicrobial, immunological, and chemical attack. A sound understanding of the microbial-host environment and its complexities, as well as the pathophysiology of venous hypertension, must be appreciated to understand the need for a multimodality approach to treating an infected venous leg ulcer. Other treatment measures are often required, in addition to systemic and topical antibiotics, such as the application of wound bandages, compression therapy, and wound debridement, which can hasten clearance of the infection and help to promote healing.

    Compression therapy is the basis for successful treatment in most patients with venous leg ulcers. Concerning compression therapy, the initial phase of decongestion and the following phase of maintenance should be differentiated. While in the maintenance phase (ulcer) stocking systems are now frequently recommended, in the decongestion phase compression bandages are mostly still used, which however are often inappropriately applied. In German-speaking countries, compression therapy with short-stretch bandages has a long tradition. However, their correct application requires good training and monitoring, which is often lacking in daily practice. Less error-prone treatment alternatives are multicomponent systems, some of which have an optical marker for the control of the correct subbandage pressure. In another new type of compression system, which is called adaptive or wrap bandages, the compression pressure can be adjusted using a Velcro fastener. Accompanying intermittent pneumatic compression therapy can also be used in the decongestion phase. Thus, there are now several different treatment options that can be used for the decongestion phase in patients with venous leg ulcers. Often bandages with short-stretch materials are very prone to errors and should in most cases be replaced by other compression systems today. The patient's preference, need, and capability should be considered when selecting the appropriate system for the individual patient.

    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.

    Hard-to-heal leg ulcers are a major cause of morbidity in the elderly population. Despite improvements in wound care, some wounds will not heal and they present a significant challenge for patients and health care providers. A multi-centre cohort study was conducted to evaluate the effectiveness and safety of a synthetic, extracellular matrix protein as an adjunct to standard care in the treatment of hard-to-heal venous or mixed leg ulcers. Primary effectiveness criteria were (i) reduction in wound size evaluated by percentage change in wound area and (ii) healing assessed by number of patients healed by end of the 12 week study. Pain reduction was assessed as a secondary effectiveness criteria using VAS. A total of 45 patients completed the study and no difference was observed between cohorts for treatment frequency. Healing was achieved in 35·6% and wound size decreased in 93·3% of patients. Median wound area percentage reduction was 70·8%. Over 50% of patients reported pain on first visit and 87·0% of these reported no pain at the end of the study. Median time to first reporting of no pain was 14 days after treatment initiation. The authors consider the extracellular synthetic matrix protein an effective and safe adjunct to standard care in the treatment of hard-to-heal leg ulcers.

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

  18. Calf muscle pump impairment and delayed healing of venous leg ulcers: air plethysmographic findings.

    2007-08-01

    There is a need for a diagnostic tool to predict clinical outcome of venous leg ulcer patients, as the prognosis of healing based on clinical data alone has not appeared to be satisfactory. Air plethysmographic assessment of calf muscle pump was performed in the supine and upright position in 129 patients with active ulcers on their legs. All patients were managed in a specialized leg ulcer clinic. Results of air plethysmography were compared to clinical data and time of healing of ulcers. Muscle pump failure was found in 42.6% of extremities (supine position, 33.3%; upright, 22.5%; both, 12.4%). Patients with insufficient pump were older, and their ulcers were larger. Failure of pump was found more often in patients who began the treatment after long, unsuccessful, non-specialized care. Healing time of ulcers was prolonged in cases with insufficient pump. Regarding the subgroups with good clinical prognosis (patients with small ulcers or with a short history of ulceration), it was found that insufficiency of muscle pump correlated with delayed healing. It could be summarized that venous leg ulcers associated with calf muscle failure were larger, long-standing, and that their healing even after specialized treatment was delayed. Impaired muscle pump function revealed in plethysmographic examination can be a prognostic factor of delayed healing of leg ulcer. Ulcers with poor prognosis according to plethysmographic findings, and no quick recovery after standard management, should be considered for advanced therapies.

    A descriptive correlational design was used to identify the physiologic, therapeutic, and psychosocial determinants of leg ulcer healing in community-residing older people with venous and venous-arterial disease (N = 156). A regression model with healing rate as the dependent variable explained 49% of the variance. Increased pain when mobilizing, increased hours with limbs horizontal to the torso, and moderate and severe liposclerosis (hardening and induration of the skin) were associated with poorer healing rates. Higher wound status scores were associated with more rapid healing rates. Self-efficacy beliefs and social support were not significant factors. The findings suggest the need for early detection and management of limb pain that interferes with normal mobility. Limb position and edema assessment prior to the application of compression bandages is recommended, with bandages that provide clients with high compression when ambulant and low compression when resting being potentially beneficial.

    This study aims to demonstrate the analgesic efficacy of electrostimulation (ES), a recognised treatment for leg ulcers. Patients treated by ES for leg ulcers between 2011 and 2013 were included in the study. The pain score obtained with the numerical rating scale (NRS) was reported before the start of the ES (D0), after 3 days (D3) and 1 week following treatment initialisation. The analgesic treatments (AT) were reported at each assessment. Seventy-three patients were included (mean age 75·19 years): 31 venous leg ulcers, 21 mixed venous leg ulcers, 2 arterial ulcers, 17 hypertensive ischaemic ulcers, 1 Hydrea(®)-induced ulcer and an amputation stump ulcer. The NRS at D0 was on average 5·3 (median = 6) while it was 2·2 at D7 (median = 2), that is P < 0·001. The results were also significant between D0 and D3 (P < 0·001). A decrease in the number of AT used was observed between D0 (2·0 AT per patient on average) and D7 (1·7 AT on average) (P < 0·001). We also observed a decrease in the consumption of grade 3 analgesics on D0 and D7 (P = 0·03). This study demonstrates the rapid analgesic efficacy of ES in leg ulcers, with a clear impact on the NRS score and especially on the decrease in analgesic consumption.

    Chronic venous stasis determines red blood cell extravasation and either dermal hemosiderin deposits or iron-laden phagocytes. Several authors have suspected that iron could play a role in the pathogenesis of venous leg ulcers. They hypothesized that local iron overload could generate free radicals or activate a proteolytic hyperactivity on the part of metalloproteinases (MMPs) or else down-regulate tissue inhibitors of MMPs. However, they were unable to explain why iron deposits, visible in the legs of patients with chronic venous disease (CVD), cause lesions in only some individuals, whereas in others they do not. We hypothesized that such individual differences could be genetically determined and investigated the role of the C282Y and H63D mutations of the HFE gene. C282Y mutation significantly increases the risk of ulcer in primary CVD more than six times (OR = 6.69; 1.45-30.8; p = 0.01). Patients carrying the H63D variant have an earlier age of ulcer onset, by almost 10 years (p > 0.004). The increased risk of skin lesion and the early age of onset of the disease in HFE carriers confirm in a clinical setting that intracellular iron deposits of mutated macrophages have less stability than those of the wild type. We hypothesize that the physiologic iron protective mechanisms are affected by the HFE mutations and should be investigated in all diseases characterized by the combination of iron overload and inflammation.

    Sulodexide, a highly purified glycosaminoglycan, was investigated for treatment of venous leg ulcers. Patients (n = 235) undergoing local treatment including wound care and compression bandaging, were randomised to receive either sulodexide or matching placebo for three months. Primary study endpoint was complete ulcer healing after 2 months; secondary endpoints were ulcer healing at 3 months and the time-course changes of ulcer areas. The proportion of patients with complete ulcer healing was higher with sulodexide at 2 months (p = 0.018) and 3 months. The "number needed to treat" to obtain one additional patient healed with sulodexide was 7 at 2 months and 5 at 3 months. The changes in ulcer surface area with time were significant for sulodexide only (p = 0.004). Fibrinogen significantly decreased in sulodexide patients (p = 0.006). In conclusion, sulodexide associated with local treatment proved to be effective and well tolerated in the management of venous leg ulcers.

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

    Introduction Leg length discrepancy (LLD) causes pelvic obliquity in the frontal plane and lumbar scoliosis with convexity towards the shorter extremity. Leg length discrepancy is observed in 3-15% of the population. Unequalized lower limb length discrepancy leads to posture deformation, gait asymmetry, low back pain and discopathy. Material and methods In the years 1998-2006, 369 children, aged 5 to 17 years (209 girls, 160 boys) with LLD-related functional scoliosis were treated. An external or internal shoe lift was applied. Results Among 369 children the discrepancy of 0.5 cm was observed in 27, 1 cm in 329, 1.5 cm in 9 and 2 cm in 4 children. During the first follow-up examination, within 2 weeks, the adjustment of the spine to new static conditions was noted and correction of the curve in 316 examined children (83.7%). In 53 children (14.7%) the correction was observed later and was accompanied by slight low back pain. The time needed for real equalization of limbs was 3 to 24 months. The time needed for real equalization of the discrepancy was 11.3 months. Conclusions Leg length discrepancy equalization results in elimination of scoliosis. Leg length discrepancy < 2 cm is a static disorder; that is why measurements should be performed in a standing position using blocks of adequate thickness and the position of the posterior superior iliac spine should be estimated.

    Ischemic ulcers remain difficult to treat. We describe a patient with bilateral ischemic leg ulcers treated preoperatively with pentoxifylline. She had a successful skin graft with no rejection of the graft. The theoretical advantage of treatment with pentoxifylline is discussed, with emphasis not only on its hemorheological properties, but also on its actions on the prostaglandin pathway, platelet aggregation, and thrombosis. We suggest that preoperative pentoxifylline treatment may be a useful adjunct in the closure of ischemic ulcers.

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

    Cultured keratinocyte grafting (KG) of chronic leg ulcers produces an impressive stimulation of host epithelization by an effect on the edge of the ulcer, which starts to grow in rapidly ("edge effect"). In 5 patients with chronic leg ulcers treated by KG, we have studied the proliferation index of the epidermis of the edge and of the graft area and that of secondary culture keratinocytes. The aim of the study was to correlate this parameter with the clinical evolution of the treated lesions. We found a significant correlation between the proliferation index of the edge epidermis and the clinical evidence of "edge effect".

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

    Chronic venous diseases are the most common causes of leg ulcers. Compression treatment (CT) is a central component of venous leg ulcer (VLU) therapy along with prevention based on guidelines and clinical evidence. However, large-scale data on the use of CT are rare. In particular, there have not yet been published nationwide data for Germany. We analysed data from a large German statutory health insurance (SHI) on incident VLU between 2010 and 2012. VLUs were identified by ICD-10 diagnoses. The status of active disease was defined by wound-specific treatments. Compression stockings and bandages were identified by SHI medical device codes. The overall estimated incident rate of active VLU of all insured persons was 0·34% from 2010 to 2012. Adapted to the overall German population, n = 229 369 persons nationwide had an incident VLU in 2010-2012. Among all VLU patients, only 40·6% received CT within 1 year, including 83·3% stockings, 31·8% bandages and 3·1% multi-component compression systems. Compression rates showed significant differences by gender and age. Large regional variations were observed. Validity of data is suggested by high concordance with a primary cohort study. Although recommended by guidelines, there is still a marked under-provision of care, with CT in incident VLUs in Germany requiring active measures.

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

    Patients living with chronic leg ulceration may frequently experience moderate to severe wound-related pain, which may not be alleviated by oral analgesics alone. Poorly controlled leg ulcer pain can prevent timely and effective wound management strategies being implemented, and increase wound healing times. Furthermore, patients with poorly controlled leg ulcer pain can experience continuous pain, which significantly affects quality of life. This case report introduces an innovative way of using the eutectic mixture of local anaesthetics (EMLA) 5% cream to reduce wound-related pain, reduce oral analgesic intake, and improve health-related quality of life for a patient with a painful, chronic lower leg ulcer.

    Gastrointestinal complications are a frequent cause of morbidity after transplantation and may affect up to 40% of kidney transplant recipients. Here we report a rare case of idiopathic giant esophageal ulcer in a kidney transplant recipient. A 37-year-old female presented with a one-week history of odynophagia and weight loss. Upon admission, the patient presented cold sores, and a quantitative cytomegalovirus polymerase chain reaction was positive (10(5) copies/mL). An upper endoscopy demonstrated the presence of a giant ulcer. Serological test and tissue biopsies were unable to demonstrate an infectious origin of the ulcer. Immunosuppression was reduced and everolimus was introduced. An empirical i.v. therapy with acyclovir was started, resulting in a dramatic improvement in symptoms and complete healing of the ulcer. Only two cases of idiopathic giant esophageal ulcer in kidney transplant recipients have been reported in the literature; in both cases, steroid therapy was successful without recurrence of symptoms or endoscopic findings. However, this report suggests that correction of immune imbalance is mandatory to treat such a rare complication.

    International guidelines on leg ulcers recommend measuring the ankle arm index (AAI) to diagnose and assess peripheral arterial occlusive disease (PAOD) of the lower limbs. These guidelines do not, however, describe the method which should be used to make the measurement: which artery should be measured -in the event of an open leg ulcer, what are the practical difficulties for positioning the cuff- how well do patients tolerate the procedure? We conducted a prospective study focusing on ease of use, tolerance and performance of AAI measurements in patients with leg ulcers. In compliance with recent French guidelines, we measured the AAI for both distal leg arteries and retained the lowest value for analysis. Within a six-month study period, 100 consecutive inpatients with leg ulcers of various etiologies were studied. Mean age was 75, female predominance 60%, body mass index 27. Etiologies of leg ulcers were pure venous (29%), mixed venous predominant (17%), pure arterial (9%), mixed arterial predominant (8%), mixed (6%), hypertensive ulcers (11%), rare cause (8%), multifactorial (12%). Pain was present in 92%, with a VAS above 3 for 73%. Measurement of AAI was possible in 98% of patients. It was too painful and thus considered unethical for two patients with hypertensive ulcers. For the 98 patients measured, the ulcer had to be protected during the measurement in 76%. The measurement procedure only took five minutes for one leg, and was judged easy to perform by 93% of the operators. For the majority (76%) of patients, the measurement was not painful. We determined the diagnostic performance of AAI by comparing the results with those of arterial ultrasound in 90 patients who had a complete arterial ultrasound exploration of the legs. Compared with arterial ultrasound, the sensitivity of AAI<0.9 for detecting the presence of PAOD was 84.7%, with 97% specificity. PAOD was not diagnosed in any patient who had two palpable distal pulses and a normal AAI. Measurement

    Recurrent chronic leg ulcers are among the most severe vasculopathic complications of sickle cell disease (SCD). Their treatment remains a challenge. Stem cell therapy with bone marrow mononuclear cells (BMMC) is a promising new therapeutic option for other forms of chronic ulcers. This prospective pilot study was performed to evaluate safety and feasibility of BMMC implantation in patients with SCD and chronic leg ulcers (SCLU). Ulcer closure, recurrence and local pain were evaluated. BMMC were successfully administered to 23 SCLU patients and no serious adverse events occurred. During the 6-month follow-up period, 91·3% of patients had improved ulcer pain compared with baseline and 29·2% of the treated ulcers achieved total healing. The frequency of progenitor stem cells (CD34CD45(low) and fibroblast colony-forming units) in BMMC was found to be significantly reduced in SCLU patients and compared to SCD patients without ulcers (P < 0·004 and P < 0·01, respectively). No relationship was observed between treatment outcome and the number of implanted BM progenitor stem cells. In conclusion, BMMC implantation is a feasible and safe procedure, showing favourable outcomes for the treatment of SCLU, and encouraging further controlled clinical trials.

    Objective: To identify and describe the qualitative variations in how physical activity is perceived and understood by individuals with current or previous venous leg ulcer. Design: A qualitative study using semi-structured interviews. Method: Twenty-two individuals aged 60–85 years were interviewed. The interviews were recorded, transcribed verbatim and analysed by three researchers using a phenomenographic research approach. A set of categories of descriptions and their internal relationships were constructed based on the essential features of the variation in patients’ perceptions of physical activity. Results: Four categories of descriptions were identified: (i) ‘self-management’, (ii) ‘instructions and support’, (iii) ‘fear of injury’ and (iv) ‘a wish to stay normal’. The categories could be interpreted by a two-dimensional construct: (1) perception of venous leg ulcer as a chronic or acute condition and (2) engagement or avoidance behaviour toward physical activity. Chronicity and behaviour combined together formed a 2 × 2 square housing the four qualitatively different categories. Irrespective of category, the participants reported that information given by caregivers regarding leg ulcer and physical activity was insufficient or contradictory. Written information or exercise programmes were not obtained regularly and not at all in primary care. Conclusion: A dichotomous view emerged from participants’ experiences of physical activity based on (1) perception of venous leg ulcer as a chronic or acute condition and (2) engagement or avoidance behaviour toward physical activity.

The aim of this study is to evaluate the quality of life, anxiety and depression, self-esteem and loneliness in patients suffering from leg ulcers. A total of 102 patients were enrolled in the study. The quality of life, anxiety and depression, self-esteem and loneliness of the patient were assessed using the Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), Rosenberg's Self-esteem Scale (RSES) and the UCLA Loneliness Scale (UCLA-Version 3), respectively. The mean DLQI score was 13·38 ± 2·59, suggesting a serious effect on the quality of life of patients. Those with leg ulcers had statistically significant higher scores according to the HADS-total scale (P = 0·031) and HADS-anxiety subscale (P = 0·015) compared with healthy volunteers. Moreover, a statistically significant difference was found between the two groups concerning the UCLA-scale (P = 0·029). Female patients presented with a higher score of anxiety (P = 0·027) and social isolation (P = 0·048), and worse quality of life (P = 0·018) than male patients. A severe quality of life impairment was documented, reflecting a significant psychosocial impact on patients with leg ulcers.

    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. PMID:27936243

  8. Health service pathways for patients with chronic leg ulcers: identifying effective pathways for facilitation of evidence based wound care

    2013-01-01

    Background Chronic leg ulcers cause long term ill-health for older adults and the condition places a significant burden on health service resources. Although evidence on effective management of the condition is available, a significant evidence-practice gap is known to exist, with many suggested reasons e.g. multiple care providers, costs of care and treatments. This study aimed to identify effective health service pathways of care which facilitated evidence-based management of chronic leg ulcers. Methods A sample of 70 patients presenting with a lower limb leg or foot ulcer at specialist wound clinics in Queensland, Australia were recruited for an observational study and survey. Retrospective data were collected on demographics, health, medical history, treatments, costs and health service pathways in the previous 12 months. Prospective data were collected on health service pathways, pain, functional ability, quality of life, treatments, wound healing and recurrence outcomes for 24 weeks from admission. Results Retrospective data indicated that evidence based guidelines were poorly implemented prior to admission to the study, e.g. only 31% of participants with a lower limb ulcer had an ABPI or duplex assessment in the previous 12 months. On average, participants accessed care 2–3 times/week for 17 weeks from multiple health service providers in the twelve months before admission to the study clinics. Following admission to specialist wound clinics, participants accessed care on average once per week for 12 weeks from a smaller range of providers. The median ulcer duration on admission to the study was 22 weeks (range 2–728 weeks). Following admission to wound clinics, implementation of key indicators of evidence based care increased (p < 0.001) and Kaplan-Meier survival analysis found the median time to healing was 12 weeks (95% CI 9.3–14.7). Implementation of evidence based care was significantly related to improved healing outcomes (p < 0

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

  10. Prevalence of skin problems and leg ulceration in a sample of young injecting drug users

    PubMed Central

    2014-01-01

    Background Drug users suffer harm from the injecting process, and clinical services are reporting increasing numbers presenting with skin-related problems such as abscesses and leg ulcers. Skin breakdown can lead to long-term health problems and increased service costs and is often the first indication of serious systemic ill health. The extent of skin problems in injecting drug users has not previously been quantified empirically, and there is a dearth of robust topical literature. Where skin problems have been reported, this is often without clear definition and generic terms such as ‘soft tissue infection’ are used which lack specificity. The aim of this study was to identify the range and extent of skin problems including leg ulceration in a sample of injecting drug users. Definitions of skin problems were developed and applied to descriptions from drug users to improve rigour. Methods Data were collected in needle exchanges and methadone clinics across Glasgow, Scotland, from both current and former drug injectors using face-to-face interviews. Results Two hundred participants were recruited, of which 74% (n = 148) were males and 26% (n = 52) were females. The age range was 21–44 years (mean 35 years). Just under two thirds (64%, n = 127) were currently injecting or had injected within the last 6 months, and 36% (n = 73) had previously injected and had not injected for more than 6 months. Sixty per cent (n = 120) of the sample had experienced a skin problem, and the majority reported more than one problem. Most common were abscesses, lumps, track marks and leg ulcers. Fifteen per cent (n = 30) of all participants reported having had a leg ulcer. Conclusions This is an original empirical study which demonstrated unique findings of a high prevalence of skin disease (60%) and surprisingly high rates of leg ulceration (15%). Skin disease in injecting drug users is clearly widespread. Leg ulceration in particular is a chronic recurring

    This study was performed to measure if the introduced interventions in leg ulcer care in a selected Swedish county yield a detectable reduction in leg ulcer prevalence in the population. A validated postal questionnaire sent to 10,000 (9,868) randomly selected 30-89 year olds in the Skaraborg county (255,042 inhabitants). All positive responders were telephone interviewed and verified ulcer patients were clinically examined including assessment of arterial/venous circulation with hand-held Doppler and, where indicated, duplex ultrasound scanning. All results were compared with numbers from 1990 (initial study). The response rate was 82% (8,070/9,868), 200 active ulcers and 290 previous ulcers. The calculated prevalence was 0.75% for 30-89 years and 1.05% for 50-89 years (2.1% in 1990). The leg ulcer prevalence was reduced by 32% (0.52% compared to 0.77% in 1990), and the relative risk was reduced by 50% (95%, CI 0.36-0.69). The study shows a true reduction in leg ulcer prevalence detectable in the population supporting a successful care of leg ulcer patients.

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

    Securing greater patient and public involvement is a central theme of health policy in many countries ( Coulter, 2011 ) and is a growing health-care phenomenon ( Staniszewska et al, 2011 ; World Health Organization, 2011 ). The challenge is how to ensure these voices are heard among the plethora of 'professional' voices representing different stakeholders of provider organisations, higher education, health-care industries and governments. Historically, in the management of leg ulcers, the professional 'user' voice has had a stronger input than that of the patient. This article outlines an approach that addresses this by moving beyond the concept of 'involving' the patient to putting the patient voice first, so that it sets the direction and leads the process in identifying innovation priorities in the management and treatment of chronic leg ulcers.

    The purpose of this paper was to examine the validity and reliability of using photographs of wounds to accurately assess wound status. The results of assessing wound appearance using wound photographs was compared to results obtained from a bedside assessment using the Pressure Sore Status Tool (PSST). The photographic wound assessment tool (PWAT) used in this comparison represents a modified version of the PSST and includes the six domains that can be determined from wound photographs. The PWAT was used on photographs of both chronic pressure ulcers (n = 56) and leg ulcers due to vascular insufficiency (n = 81). The photographic tool has excellent intrarater (ICC = 0.96) and interrater (ICC = 0.73) reliability and good concurrent validity (r = 0.70) compared with a full bedside assessment PSST. The PWAT has also shown to be sensitive to change in wound appearance of healing ulcers, but not nonhealing ulcers. These results would suggest that in the event that a full bedside assessment is not possible, wound photographs may be used to accurately assess wound appearance of both chronic pressure ulcers located on the trunk and vascular ulcers of the lower extremity. Establishing a valid and reliable assessment of wound healing using photographic images is of great relevance to the advancing fields of computer image analysis and telemedicine.

    Chronic venous insufficiency is a prevalent disease that frequently leads to development of venous leg ulcers. While a number of evidence-based clinical practice guidelines have been developed that provide guidance for clinicians when caring for patients with chronic venous insufficiency, they lack adequate detail concerning selection and application of compression for prevention and management of venous leg ulcers. In order to address this need, the WOCN Society appointed a task force to develop an algorithm for compression for primary prevention, treatment, and prevention of recurrent venous leg ulcers in persons with chronic venous insufficiency. The task force used findings from a scoping literature review to identify current best evidence needed to support decision points and pathways within the algorithm. In addition, the task force convened a panel of 20 clinicians and researchers with expertise in lower extremity venous disorders in order to establish consensus around pathways and decision points within the algorithm lacking robust evidence. Following initial construction of the algorithm, a second interdisciplinary group of expert clinicians established content validity and provided additional qualitative feedback used to complete final revisions of the algorithm. This article reviews the process used to create this landmark algorithm, including generation of the evidence- and consensus-based statements used in its construction, the various pathways, and rich supplemental materials embedded within the algorithm, and the process used to establish content validity.

    BACKGROUND Chronic leg ulcer may have an impact on patients' quality of life. OBJECTIVES This study aimed to identify the impact of leg ulcers on patient's quality of life using the Dermatology Life Quality Index and to define the main factors correlated with this perception. METHOD Cross-sectional, non-probabilistic sampling study. We included patients with chronic leg ulcers being treated for at least 3 months. A sociodemographic and clinical survey was conducted to assess the profile of the ulcers. We administered a screening for depressive symptoms and the Dermatology Life Quality Index. We performed a descriptive statistical analysis, chi-square test and Mann-Whitney test for categorical data, Pearson for numeric variables, and multiple regression for categorical data. RESULTS Forty-one patients were assessed. Their mean age was 61.78 years. Venous ulcers (48.8%) were the most prevalent. Seventy-three percent of the sample perceived no impact/low impact on quality of life in the past week, and 26.8% perceived moderate/high impact. A multiple regression analysis identified the causes of lesion, pain related to the ulcers, time of onset, and severity of the depressive symptoms as the variables that had an influence on quality of life. CONCLUSIONS The majority of the sample perceived low or no impact of the condition on the quality of the life. The variables etiology of the lesion (p<0.001), pain related to the ulcers (p=0.001), time of onset (p=0.006), and severity of the depressive symptoms (p<0.001) had an influence on the quality of life, suggesting the need for further studies with more robust designs to confirm the causal relationship between these characteristics and quality of life.

      A clinical pathway (CP) was developed and implemented to improve treatment outcomes for patients with venous leg ulcers. The CP and products (Rosidal® sys, Suprasorb® A, Suprasorb® P, and Suprasorb® C, Lohmann & Rauscher GmbH, Rengsdorf, Germany) were tested by case evaluation. Patients from the center were examined to determine his or her general condition, associated factors, wound type and stage, wound evolution, quality of life (QOL), treatment efficacy, and costs. Patients with venous leg ulceration (N = 20) were recruited to the clinical evaluation. Examination was performed upon presentation, and then at 2-week intervals for 12 weeks. The patients were then followed until ulcer closure. The outcome of the study group (SG) was compared to the results of a randomly selected patient control group (CG) at the center before implementing the clinical pathway. Statistic evaluation was performed using StatXact 5.0, double sided (α = 0.05) for paired and Wilcoxon test, and unpaired with Mann-Whitney (N = 20, [10/10]). After implementation, a statistically significant (P < 0.005) shorter period for ulcer closure was demonstrated for the SG when compared to previous treatment given to the CG. In the SG, 5/10 ulcers closed within 12 weeks versus 3/10 in the CG. An improvement in QOL was noted for the SG (P < 0.05 for the combined parameters, and P < 0.005 for pain), as well as cost savings (P < 0.05). The CP applied throughout the complete care chain improved quality of treatment outcomes and made effective use of resources and materials.

    Debridement plays an essential role in the wound-bed preparation of necrotic and sloughy ulcers, being a mandatory step to achieve a well-debrided bed, proceeding towards healing. This study reports our experience with Versajet [Versajet Hydrosurgery System (Smith & Nephew, Hull, UK)], a new device for the debridement of exudating ulcers, based on Fluidjet technology, which excises and aspirates the unwanted tissue by using the Venturi effect. In a 10-month time period, a total of 68 patients, out of a setting of 167 patients, hospitalised as affected by chronic, hard-to-heal leg ulcers, stuck in the inflammatory phase, were treated with Versajet. Based on ulcer characteristics and clinical conditions, the remaining 99 patients underwent traditional debridement with moist dressings (controls). In the majority of Versajet-treated cases (46), an adequately debrided wound bed was achieved with one operative procedure; two and three procedures were required in 17 and 5 patients, respectively. Almost all the procedures were performed in the ward at the patient's bedside. This procedure is quick (mean time per treatment is about 5 minutes); when compared with a traditional treatment with moist dressings, Versajet considerably shortens the in-hospital stay and promotes a quicker healing process. When used by an experienced surgeon, Versajet allows a selective debridement, as it makes it possible to remove only the tissue centred in the working end and spare the healthy tissue. Debriding with Versajet is highly effective in reducing the bacterial load of the ulcer bed. The pain caused by Versajet is well tolerated, especially when set for gentle debridement. If multiple treatments are required, the combined use with moist dressings is synergistic, as the dressings soften the necrotic tissue, thus facilitating the following Versajet debridement. The results indicate that Versajet offers more precision than standard mechanical debridement and, at high settings, offers an

    Cutaneous polyarteritis nodosa, a special form of polyarteritis nodosa (PAN) without systemic involvement, is classified as one of the ANCA-negative vasculitides of small and medium-sized vessels. It is a very rare disease with unknown etiology and occurs more commonly in women over the age of 40. Typical skin lesions are subcutaneous nodules, livedo racemosa, and ulcerations. We report the case of a 46-year-old woman presenting to our outpatient department who reported having very painful ulcerations of the lower legs with unknown origin for 6 months.

    Clinical features and potential risk factors for chronic leg ulceration (duration >6 months) in homozygous sickle cell (SS) disease were examined in 225 subjects in the Jamaican Cohort Study. Potential risk factors included the number of HBA genes, steady state haematology, serum lactate dehydrogenase (LDH), venous incompetence, and socio-economic status. Chronic ulcers occurred in 53 subjects with the highest risk of ulcer development at 18 years. The prevalence was 29.5% and cumulative incidence 16.7%. Gender or alpha-thalassaemia trait did not affect the incidence of leg ulcer. Ulceration was associated with lower haemoglobin, red cell count, fetal haemoglobin, and socio-economic status and higher reticulocyte count, platelet count, serum LDH and venous incompetence in univariate analyses. Venous incompetence [Hazard Ratio (HR) 3.0-4.0] and socio-economic status (HR 0.8) were most consistently associated with leg ulceration on multivariate analysis. Regression models incorporating serum LDH suggested this to be a stronger predictor than haematological indices. The prevalence of ulcers at 30% is less than previous estimates in Jamaica, probably reflecting the lack of ascertainment bias in the Cohort Study, and also a real secular decline. In Jamaica, venous incompetence, low socio-economic status, and high serum LDH were the strongest predictors of chronic ulceration.

  1. Evaluation and treatment of leg ulcers associated with chronic venous insufficiency.

    PubMed

    Marston, William

    2007-10-01

    The successful management of patients who have leg ulcers related to chronic venous disease requires optimal management of the wound bed, elimination of edema with compression, and correction of venous hypertension whenever possible. Healing of the wound itself requires compression, debridement, bacterial control, and stimulation of the wound bed. Prevention of ulcer recurrence is most effective if the patient is amenable to correction of the venous insufficiency. This is most successful when the superficial or perforator veins are the primary source. Quality diagnostic studies are critical in determining the anatomy and hemodynamic importance of various venous abnormalities and can guide appropriate interventional treatment. Venous corrective procedures usually can be performed using minimally invasive endovenous methods, which are associated with fewer complications and more rapid recovery than are major surgical techniques.

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

    Aim of the study was to evaluate the efficacy, tolerance and safety of treatment of leg ulcer with pentoxiphylline administered orally in daily dose of 1200 mg divided for 3 doses for six months. The study was carried out in 19 centres in Poland. The results of clinical and laboratory (HGB, WBC, PTL) examinations made before, during and after treatment were documented in individual case-records. Pentoxiphylline was administered to 184 patients (124 F and 60 M) aged 22-86 (mean-61.6) yrs. One hundred and thirty-five patients had non-arterial ulcers, 37-partly arterial and 12-arterial. The duration of the disease was 1 to 1620 (mean 158) weeks. Resting pain was reported by 131 patients. In 9 persons the treatment was stopped after 1-2 months; in 6 (3%) of them due to side effects. In 175 patients pentoxiphylline was administered as follows: 1200 mg daily for 6 months in 92 cases, 1200 mg daily for 2-5 months--in 58, 1200 mg daily for 3-5 months and 800 mg daily for next 1-3 months--in 12 cases, and 800 mg daily for 1-6 months--in 13 cases. In 161 (92%) cases a beneficial effect was achieved including complete healing of the ulcers in 79 (45%) or improvement in 82 (47%); in 14 (8%) there was no improvement. The resting pain was significantly reduced in 114 (87%) patients within 1-24 weeks and completely disappeared in 69 (53%) patients within 2-20 weeks of treatment. No significant abnormalities in the results of laboratory tests were found. Transient side effects of the therapy appeared in 11 patients but they did not require administration of the drug to be discontinued. The study showed that pentoxiphylline is a effective, well tolerated and safe drug in the treatment of leg ulcers.

    Transcutaneous oxygen tension (TcPO2) and the effect of intermittent pneumatic compression on tissue oxygenation were studied in 10 patients with post-thrombotic leg ulcers. Oxygen tension was measured near the edge of the leg ulcer before and after 60 min of intermittent compression at 50 mmHg. The control group consisted of nine subjects with no evidence of peripheral vascular disease. The mean TcPO2 for the controls was 59.7 (SEM2.9) mmHg and for the study group 26.2 (SEM7.0) mmHg before treatment and 42.7 (SEM6.4) mmHg after treatment (p less than 0.005). Oxygen tension increased in nine patients in the study group. The change in TcPO2 correlated highly significantly (r = 0.912, p less than 0.002) with the reduction of oedema and the inverse change of skin temperature. The results suggest that intermittent pneumatic compression decreases interstitial fluid volume and venous stasis, both of which may lead to increased tissue oxygenation.

    Several recent advances in wound care may offer promise for the treatment of hard-to-heal venous leg ulcers. One such treatment is Apligraf (Graftskin), a bilayered, living human skin construct. To assess the economic impact of Graftskin, a model was constructed to compare the annual medical costs and cost-effectiveness of treating hard-to-heal venous leg ulcers with Graftskin vs. compression therapy using Unna's boot. A semi-Markov model was used to describe the pattern of ulcer treatment, healing, and recurrence among patients with venous leg ulcers. Patients received 1 of 2 treatment regimens, Graftskin or Unna's boot, and were followed in the model for a 12-month period. The analysis was done from the perspective of a commercial health plan; therefore, only direct medical costs were included. Health care resource use included the primary therapeutic intervention, additional compression dressings, physician office visits, home health visits, laboratory tests and procedures, management of adverse events, and hospitalizations. The model estimated the annual medical cost of managing patients with hard-to-heal venous leg ulcers to be $20,041 for those treated with Graftskin and $27,493 for those treated with Unna's boot. In addition, treatment with Graftskin led to approximately 3 more months in the healed state per person per year than did treatment with Unna's boot. Because patients treated with Graftskin experienced improved healing compared with those treated with compression therapy using Unna's boot, they required fewer months of treatment for unhealed ulcers. As a result, the use of Graftskin for treating hard-to-heal venous leg ulcers resulted in lower overall treatment costs.

Regarding the reduction of the symptoms: ulcer extension, coldness of the leg, paraesthesia, resting pain and improvement of walking distance, 215 patients were classified as considerably improved, 195 distinctly improved, 53 slightly improved and 44 unchanged. Four cases worsened, two cases could not be classified. The possibility of combining oral therapy with local treatment and surgical measures (skin-flaps) is shown in three case reports. Gastro-intestinal tolerance of Trental 400 was good, interactions with concomitantly administered drugs were not reported.

    Peptic ulcer disease is a significant cause of morbidity and in certain cases mortality among affected individuals. Proper identification and treatment of peptic ulcer disease is imperative to decreasing its associated sequellae. The most common causes of peptic ulcer disease are the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and infection with Helicobacter pylori. Initial assessment of the patient with dyspepsia is paramount, as the presence of symptoms will dictate further management. With currently available treatment regimens and the ability to reduce gastrointestinal bleeding it is important for all clinicians to have knowledge of this disease, its diagnosis, and pharmacotherapy.

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

    Piriformis syndrome (PS) is an uncommon neuromuscular disorder caused by the piriformis muscle (PM) compressing the sciatic nerve (SN). The main symptom of PS is sciatica, which worsens with certain triggering conditions. Because the pathophysiology is poorly understood, there are no definite diagnostic and therapeutic choices for PS. This case report presents a young woman who mainly complained of bilateral leg weakness. Electromyography revealed bilateral sciatic neuropathy and magnetic resonance imaging confirmed structural lesions causing entrapment of the bilateral SNs. After a laborious diagnosis of bilateral PS, she underwent PM releasing surgery. Few PS cases present with bilateral symptoms and leg weakness. Therefore, in such cases, a high level of suspicion is necessary for accurate and prompt diagnosis and treatment. PMID:26798622

    We present the case of a 63-year-old white male with bilateral chronic leg ulcers due to polycythemia vera and hydroxyurea therapy who demonstrated dramatic healing of his wounds in response to ruxolitinib (Jakafi®, Novartis), a novel Janus kinase-1 and -2 inhibitor. This patient’s wound had previously been refractory to multiple surgical interventions and immunosuppression. After the initiation of ruxolitinib, the patient underwent successful split-thickness skin grafting, with resultant healing of his wounds. He was stable without prednisone and other immunosuppressant therapy and had healed at 6 months. Ruxolitinib therapy could represent a novel option for patients who develop persistent inflammatory wounds in the setting of polycythemia vera and hydroxyurea therapy. PMID:23953278

    This article presents the findings of an audit on venous leg ulceration prevalence in a community area as a framework for discussing the concept and importance of audit as a tool to inform practice and as a means to benchmark care against national or international standards. It is hoped that the discussed audit will practically demonstrate how such procedures can be implemented in practice for those who have not yet undertaken it, as well as highlighting the unexpected extra benefits of this type of qualitative data collection that can often unexpectedly inform practice and influence change. Audit can be used to measure, monitor and disseminate evidence-based practice across community localities, facilitating the identification of learning needs and the instigation of clinical change, thereby prioritising patient needs by ensuring safety through the benchmarking of clinical practice.

    BACKGROUND Compression is an effective and recommended treatment for venous leg ulcers. Although the four-layer bandage (4LB) is regarded as the gold standard compression system, it is recognised that the amount of compression delivered might be compromised by poor application technique. Also the bulky nature of the bandages might reduce ankle or leg mobility and make the wearing of shoes difficult. Two-layer compression hosiery systems are now available for the treatment of venous leg ulcers. Two-layer hosiery (HH) may be advantageous, as it has reduced bulk, which might enhance ankle or leg mobility and patient adherence. Some patients can also remove and reapply two-layer hosiery, which may encourage self-management and could reduce costs. However, little robust evidence exists about the effectiveness of two-layer hosiery for ulcer healing and no previous trials have compared two-layer hosiery delivering 'high' compression with the 4LB. OBJECTIVES Part I To compare the clinical effectiveness and cost-effectiveness of HH and 4LB in terms of time to complete healing of venous leg ulcers. Part II To synthesise the relative effectiveness evidence (for ulcer healing) of high-compression treatments for venous leg ulcers using a mixed-treatment comparison (MTC). Part III To construct a decision-analytic model to assess the cost-effectiveness of high-compression treatments for venous leg ulcers. DESIGN Part I A multicentred, pragmatic, two-arm, parallel, open randomised controlled trial (RCT) with an economic evaluation. Part II MTC using all relevant RCT data - including Venous leg Ulcer Study IV (VenUS IV). Part III A decision-analytic Markov model. SETTINGS Part I Community nurse teams or services, general practitioner practices, leg ulcer clinics, tissue viability clinics or services and wound clinics within England and Northern Ireland.

    The aim of the study was to determine the prevalence rate for inherited thrombophilia (IT) in patients with chronic (CVU) and recurrent venous leg ulceration. We also investigated and evaluated the severity of the clinical pattern of CVU in patients with and without IT. We examined 110 patients with CVU (the study group) and 110 healthy subjects (the control group). We prepared a questionnaire to be completed by each study participant. Ultrasound Doppler color imaging or/and duplex ultrasonography was performed to evaluate the efficiency of the venous system. The ankle-brachial index was calculated to determine the efficiency of the arterial system. We examined both groups for the presence of IT. IT was diagnosed in 30% of study group and in 1.8% of control group. Our diagnoses of deep vein thrombosis (DVT) were based on medical interviews, physical examinations, and an ultrasonography of the venous system and concerned 64 study group patients (58.2%), 35 of whom (31.8%) experienced recurrent DVT. Proximal and/or distal DVT was determined in an interview and/or by an ultrasonography performed for all patients with CVU and IT. In 94% of these patients, DVT was recurrent, and in 88% of patients with CVU and IT, we observed recurrent DVT and CVU. It recurred more often and persisted longer when compared to patients with CVU and no IT, despite similar management. No differences were observed in ulcer size, localization, or pain level related to ulceration between patients with CVU and IT and those with CVU and no IT.

    Chronic wounds such as diabetic foot ulcers (DFU) and venous leg ulcers (VLU) may take a long time to heal and increase the risk of complications. Previous studies have suggested human skin allograft may facilitate healing of these chronic wounds. A retrospective, descriptive study was conducted among outpatients with nonhealing DFU, VLU, surgical, or traumatic wounds managed with a meshed, partial-thickness, cryopreserved human skin allograft. Charts of all patients who received an allograft from 2011 to 2013 were abstracted if the wound was >1 cm2, had a duration>30 days, was adequately debrided, and was free of infection before the first allograft application. Primary outcome was percentage of wounds healed (ie, 100% epithelialized) at 12 and 20 weeks. Secondary outcome was the number of recorded adverse events. Wound measurements (area--calculated as width x length in cm2), wound type and duration, number of allograft applications, number of adverse events, and race, smoking status, and body mass index were abstracted. Of the 49 patients (average age 64.3 [SD 15.0]; 64% male) who met the inclusion criteria, 13 did not have medical follow-up through the primary outcomes at 12 and 20 weeks, leaving 36 patients (average age 65.1 [SD 15.4]; 67% male) available for analysis. The most common diagnoses were VLU (18 patients, 50%) and traumatic wounds (9 patients, 25%). Average wound size was 19.4 cm2 (SD 29.3, range 1.2-156, median 9.5), and average wound duration at initial treatment was 17.2 (SD 17.0, range 4-72, excluding outlier) weeks. Seventeen (17) wounds (47%) healed by 12 weeks, and 21 (58%) were healed by week 20 with an average of 3.3 (SD 2.0) allograft applications. No serious adverse events occurred. The results of this study are encouraging and add to the currently available literature on the use of allograft skin for chronic wounds, but the study design and sample size limit the ability to interpret the observations.

    Venous leg ulcers affect millions of patients worldwide and are a tremendous financial burden on our healthcare system. The hallmark of venous disease of the lower extremities is venous hypertension, and compression is the current mainstay of treatment. However, many patients are noncompliant, in part because of the complexity of the dressings and the difficulties with application and removal. The aim of our study was to determine an effective compression dressing regimen for patients with venous leg ulcers who require changing the ulcer primary dressing twice daily. We used two layers of a latex free tubular elastic bandage for compression. The primary endpoint of our study was increased wound healing rate and our secondary endpoint was complete wound closure. All active study subjects had positive healing rates at week 4 and week 8. Two subjects achieved complete wound closure by week 8. We conclude that compression with a latex-free tubular elastic bandage can be safely used in patients with venous leg ulcers requiring frequent dressing changes. This type of compression allows for daily inspection of wounds, dressing changes at home, flexibility in the context of clinical trials, and is a compromise for patients that are intolerant to compression dressings.

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

    Chloroquine-proguanil association is recommended for prophylaxis against falciparum malaria in countries with a low prevalence of chloroquine resistance. It is usually well tolerated with mild side effects consisting mainly of transient digestive discomfort and buccal manifestations (mouth sores or ulcers). The purpose of this report is to describe a case of duodenal ulcers presenting as epigastric pain with 10-kg weight-loss in a 32-year-old man taking chloroquine-proguanil for malaria prophylaxis during a stay in Haiti. No other causes of duodenal ulcers or weight-loss were found. Chloroquine-proguanil prophylaxis was discontinued and replaced by omeprazole for four weeks. Symptoms improved quickly and full recovery was observed within one month. To our knowledge, the occurrence of duodenal ulcers under chloroquine-proguanil association is quite rare, but possibly severe. Upper digestive endoscopy should be performed if a patient under chloroquine-proguanil develops abdominal pain especially in association with weight-loss. If endoscopy reveals duodenal ulcers, chloroquine-proguanil should be discontinued and replaced by another prophylactic regimen.

    2015-08-01

    A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed was: In patients with chronic venous leg ulcers (CVLU), does the use of medical grade honey as compared to standard wound therapy improve clinical outcomes? A total of 299 papers were identified using the search protocol described, of which five represented the best evidence available to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Two randomised controlled trials arrived at contradictory conclusions: one showing better outcomes for CVLU healing with use of honey over standard wound therapy and the other showing equivalent outcomes but more adverse effects. A third randomised controlled trial showed a non-significant reduction in bacterial colonisation of CVLU with honey compared to standard therapy. Two further studies--a prospective cohort study and a case series--supported the use of honey, but these were of lower grade evidence and had numerous methodological faults. Therefore, the clinical bottom line is that there is no conclusive evidence that honey improves outcome in patients with CVLU, and until more robust trials are conducted, its benefit should be considered unproven.

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

    Leg ulcer is a disabling complication in patients with sickle cell anemia (SCA) but the exact pathophysiological mechanisms are unknown. The aim of this study was to identify the hematological and hemorheological alterations associated with recurrent leg ulcers. Sixty-two SCA patients who never experienced leg ulcers (ULC-) and 13 SCA patients with a positive history of recurrent leg ulcers (ULC+)--with no leg ulcers at the time of the study--were recruited. All patients were in steady state condition. Blood was sampled to perform hematological, biochemical (hemolytic markers) and hemorheological analyses (blood viscosity, red blood cell deformability and aggregation properties). The hematocrit-to-viscosity ratio (HVR), which reflects the red blood cell oxygen transport efficiency, was calculated for each subject. Patients from the ULC+ group were older than patients from the ULC- group. Anemia (red blood cell count, hematocrit and hemoglobin levels) was more pronounced in the ULC+ group. Lactate dehydrogenase level was higher in the ULC+ group than in the ULC- group. Neither blood viscosity, nor RBC aggregation properties differed between the two groups. HVR was lower and RBC deformability tended to be reduced in the ULC+ group. Our study confirmed increased hemolytic rate and anemia in SCA patients with leg ulcers recurrence. Furthermore, our data suggest that although systemic blood viscosity is not a major factor involved in the pathophysiology of this complication, decreased red blood cell oxygen transport efficiency (i.e., low hematocrit/viscosity ratio) may play a role.

    This was an open-label, prospective, multicentre, randomised controlled study to evaluate the efficacy and safety of human fibroblast-derived dermal substitute (HFDS) plus four-layer compression therapy compared with compression therapy alone in the treatment of venous leg ulcers. The primary outcome variable was the proportion of patients with completely healed study ulcers by 12 weeks. The number healed was further summarised by ulcer duration and baseline ulcer size. Sixty-four (34%) of 186 patients in the HFDS group experienced healing by week 12 compared with 56 (31%) of 180 patients in the control group (P = 0·235). For ulcers ≤ 12 months duration, 49 (52%) of 94 patients in the HFDS group versus 36 (37%) of 97 patients in the control group healed at 12 weeks (P = 0·029). For ulcers ≤ 10 cm(2), complete healing at week 12 was observed in 55 (47%) of 117 patients in the HFDS group compared with 47 (39%) of 120 patients in the control group (P = 0·223). The most common adverse events (AEs) were wound infection, cellulitis and skin ulcer. The frequency of AEs did not markedly differ between the treatment and control groups.

  5. Clinical implications of gene polymorphisms in venous leg ulcer: a model in tissue injury and reparative process.

    2007-07-01

    Wound healing is a multi-step process involving complex pathways at cell and molecular level. Lack of understanding of the molecular mechanisms and pathogenesis of impaired healing in chronic leg ulcers limits clinical assessment and management. In addition, individual genetic background certainly affects the response to treatment and specifically modulates the unfavourable lesion environment. Although the number of actors involved in the aetiology of chronic wounds is extremely high, the ability to find out groups of candidate genes on the basis of clinical and physio-pathological findings is a crucial step. The present review demonstrates how recognition of functional gene variants, mostly single nucleotide polymorphisms (SNPs), significantly involved in wound healing and venous ulcer establishment, extraordinarily helps prognosis, diagnosis and treatment of chronic wounds. We deal with on how one can manage SNPs in coagulation factor XIII (FXIII) and hemochromatosis (HFE) genes as molecular markers or prognostic tools. In this fashion, we could pave the way for strategies aimed to single out in advance categories of patients at increased risk to develop severe complications of chronic venous disorders, or to predict the healing time after surgical intervention. Because of its relevant epidemiology and its easily visualized lesions, venous leg ulcer is an ideal model for investigating, the mechanisms of tissue injury and reparative process, as well as the influence of different genetic backgrounds.

    IntroductionA root cause analysis was performed on the occurrence of gastroduodenal ulceration after hepatic radioembolization (RE). We aimed to identify the risk factors in the treated population and to determine the specific mechanism of nontarget RE in individual cases. Methods: The records of 247 consecutive patients treated with yttrium-90 RE for primary (n = 90) or metastatic (n = 157) liver cancer using either resin (n = 181) or glass (n = 66) microspheres were reviewed. All patients who developed a biopsy-proven microsphere-induced gastroduodenal ulcer were identified. Univariate and multivariate analyses were performed on baseline parameters and procedural data to determine possible risk factors in the total population. Individual cases were analyzed to ascertain the specific cause, including identification of the culprit vessel(s) leading to extrahepatic deposition of the microspheres. Results: Eight patients (3.2 %) developed a gastroduodenal ulcer. Stasis during injection was the strongest independent risk factor (p = 0.004), followed by distal origin of the gastroduodenal artery (p = 0.004), young age (p = 0.040), and proximal injection of the microspheres (p = 0.043). Prolonged administrations, pain during administration, whole liver treatment, and use of resin microspheres also showed interrelated trends in multivariate analysis. Retrospective review of intraprocedural and postprocedural imaging showed a probable or possible culprit vessel, each a tiny complex collateral vessel, in seven patients. Conclusion: Proximal administrations and those resulting in stasis of flow presented increased risk for gastroduodenal ulceration. Patients who had undergone bevacizumab therapy were at high risk for developing stasis.

    Biatain and Biatain-Ag are two identical wound dressings except the fact that Biatain-Ag releases silver. In the present multinational double-blinded randomised controlled trial the effect of the two dressings were compared for treatment of venous leg ulcers. A total of 181 patients were treated for 6 weeks with either Biatain or Biatain-Ag followed by 4 weeks treatment with Biatain. Biatain-Ag showed superior performance in relative wound area reduction after 6 weeks treatment and the estimated treatment difference increased after 10 weeks indicating that the effect of silver continues at least for 4 weeks after treatment. A subgroup of the patients differed significantly from the others with respect to parameters associated with a poor healing prognosis; patients were older, had significant history of venous thrombosis, larger ulcers with longer duration and more often recurrent. For this subgroup of patients Biatain-Ag showed significant (P < 0·05) better performance in terms of relative ulcer area reduction and healing rate. In conclusion, this study suggests the superior performance of Biatain-Ag compared with the non silver-releasing dressing Biatain in particular for patients having ulcers associated with a poor healing prognosis.

    BACKGROUND Venous ulcers have a significant impact on patient quality of life, and constitute a worldwide public health problem. Treatment is complex, with high failure rates. OBJECTIVES To identify clinical and therapeutic factors that influence healing of venous ulcers. METHODS Retrospective cohort study of patients with venous ulcers. Ulcer area was measured at the first visit (T0) and after 6 months (T6) and 1 year (T12). A reduction in ulcer area of 50% or more at T6 and T12 was the outcome of interest, weighted by clinical, demographic and treatment aspects. RESULTS Ninety-four patients were included (137 ulcers). A reduction in ulcer area of 50% or more was seen in 40.1% of patients (95%CI 31.9 to 48.4%) at T6 and 49.6% (95%CI 41.2 to 58.1%) at T12. Complete healing occurred in 16.8% (95%CI 10.5 to 23.1%) at T6 and 27% (95%CI 19.5 to 39.5%) at T12. The lowest ulcer area reductions at T6 were associated with longstanding ulcer (RR=0.95; 95%CI 0.91 to 0.98), poor adherence to compression therapy (RR=4.04; 95%CI 1.31 to 12.41), and infection episodes (RR= 0.42; 95%CI 0.23 to 0.76). At T12, lower reductions were associated with longstanding ulcer (RR=0.95; 95%CI 0.92 to 0.98), longer topical antibiotic use (RR=0.93; 95%CI 0.87 to 0.99), and systemic antibiotic use (RR=0.63; 95%CI 0.40 to 0.99). CONCLUSIONS Longstanding ulcer, infection, poor adherence to compression therapy, and longer topical and systemic antibiotic use were independently correlated with worse healing rates. PMID:24937814

    Patients with sickle cell disease are known to have recurrent lower extremity ulcers that have a high pain score and are resistant to conventional means of wound therapy. This study reports the successful use of synthetic heparan sulphate (Cacipliq20(®) , OTR3, Paris, France) in the treatment of a sickle cell ulcer that had failed to respond to several other means of treatment. Therapeutic success was assessed by complete wound coverage and vast improvement in pain score. This is the first study to report use of heparan sulphate in sickle cell ulcers.

    Previous reports differ as to whether a decreased elongation index (EI), a proxy for red blood cell (RBC) deformability, is associated with leg ulcers (LU) in people with homozygous sickle cell disease (SCD). We sought to determine whether erythrocyte deformability (ED) and haematological indices were associated with the presence of LU in patients with SCD. The study design was cross-sectional. Twenty-seven patients with LU and 23 with no history of ulceration were recruited into the study. A laser assisted rotational red cell analyzer was used in the determination of the EI. Haematological indices were determined using a CELL-DYN Ruby haematology analyzer. Data were normally distributed and presented as means±SD. Two-sample t-test was used to test for associations between haemorheological variables in SCD patients with and without LU. Statistical significance was taken as p < 0.05. The EI was significantly lower in the group with ulcers (0.30±0.07 vs. 0.35±0.07, p = 0.02). Haematological indices were comparable in patients with and without LU. Erythrocyte deformability, but not haematological indices, was associated with LU in patients with SCD.

    Chronic venous ulcer can often be associated with asymptomatic peripheral arterial disease (PAD), which usually remains undiagnosed adding significantly to the morbidity of these patients. The Ankle-Brachial Pressure Index (ABPI) is suggested for PAD evaluation. Many PAD studies were conducted in western countries, but there is a scarcity of data on the prevalence of PAD in clinical venous ulcer patient in developing countries. We conducted a study in a tertiary care hospital of eastern part of India to find out the prevalence of PAD in venous ulcer patients, and also to find the sensitivity of ABPI as a diagnostic tool in these patients. We evaluated clinically diagnosed patients with venous ulcer using ABPI and Colour Doppler study for the presence of PAD. Possible associations such as age, sex, body mass index (BMI), smoking, hypertension and atherosclerosis were studied. All results were analysed using the software Statistica version 6. PAD was present in 23 (27·71%) patients. Older age, longer duration, smoking, high BMI and hypertension were found to be significantly associated with PAD. A very strong level of agreement was found between venous Doppler and ABPI. Assessment for the presence of PAD is important in all clinically diagnosed venous ulcer patients. ABPI being a simple, non-invasive outpatient department (OPD)-based procedure, can be routinely used in cases of venous ulcer to find out the hidden cases of PAD even in developing countries.

  14. Testing the effectiveness of a self-efficacy based exercise intervention for adults with venous leg ulcers: protocol of a randomised controlled trial

    2014-01-01

    Background Exercise and adequate self-management capacity may be important strategies in the management of venous leg ulcers. However, it remains unclear if exercise improves the healing rates of venous leg ulcers and if a self-management exercise program based on self-efficacy theory is well adhered to. Method/design This is a randomised controlled in adults with venous leg ulcers to determine the effectiveness of a self-efficacy based exercise intervention. Participants with venous leg ulcers are recruited from 3 clinical sites in Australia. After collection of baseline data, participants are randomised to either an intervention group or control group. The control group receive usual care, as recommended by evidence based guidelines. The intervention group receive an individualised program of calf muscle exercises and walking. The twelve week exercise program integrates multiple elements, including up to six telephone delivered behavioural coaching and goal setting sessions, supported by written materials, a pedometer and two follow-up booster calls if required. Participants are encouraged to seek social support among their friends, self-monitor their weekly steps and lower limb exercises. The control group are supported by a generic information sheet that the intervention group also receive encouraging lower limb exercises, a pedometer for self-management and phone calls at the same time points as the intervention group. The primary outcome is the healing rates of venous leg ulcers which are assessed at fortnightly clinic appointments. Secondary outcomes, assessed at baseline and 12 weeks: functional ability (range of ankle motion and Tinetti gait and balance score), quality of life and self-management scores. Discussion This study seeks to address a significant gap in current wound management practice by providing evidence for the effectiveness of a home-based exercise program for adults with venous leg ulcers.

    Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

    This study reports the case of a 47-year old female with low back pain radiating to groin and anterior regions of the left thigh and leg. At symptoms onset, electromyography showed left L3-L4 radiculopathy, and nuclear magnetic resonance revealed disc protrusion at the same level with impingement of the spinal nerve root. The clinical symptoms were ascribed to lumbar disco-radicular conflict. The patient underwent steroidal anti-inflammatory treatment with epidural steroid injections, chiropractic spinal manipulations and rehabilitation program, with no relief. Thirteen months after the onset of pain, a computed tomography of sacroiliac joints showed osteolytic lesion in the iliac bone of left joint, and a bone scintigraphy highlighted foci of intense uptake at left iliac bone and left proximal extremity of the femur. The bone biopsy and pathological examinations showed findings consistent with large B-cell non-Hodgkin lymphoma. This case report highlights the fact that in making differential diagnosis of low back pain radiating to the leg we have to consider the rare possibility that pain can be due to non-Hodgkin lymphoma that involves simultaneously the iliac bone and proximal extremity of the femur.

    Venous leg ulcers (VLUs) affect millions of patients worldwide and are a tremendous financial burden on our health care system. The hallmark of venous disease of the lower extremities is venous hypertension, and compression is the current mainstay of treatment. However, many patients are non-compliant, partly because of the complexity of the dressings and the difficulties with application and removal. The aim of our study was to test an effective compression dressing regimen for patients with VLUs who require changing the ulcer primary dressing twice daily. We used two layers of a latex-free tubular elastic bandage for compression. The primary endpoint of our study was increased wound-healing rate and our secondary endpoint was complete wound closure. All active study subjects had positive healing rates at week 4 and week 8. Two subjects achieved complete wound closure by week 8. We conclude that compression with a latex-free tubular elastic bandage can be safely used in patients with VLUs requiring frequent dressing changes. This type of compression allows for daily inspection of wounds, dressing changes at home, flexibility in the context of clinical trials, and is a compromise for patients who are intolerant to compression dressings.

    Three hundred thirty-nine of 400 chronic cutaneous ulcers in 264 patients (including some with multiple or bilateral ulcers of both) were healed with silver-zinc-allantoinate creamed (AZAC 1%). Some of the patients treated had failed to respond to medicated wrappings, saline dressings, and various other therapeutic agents, including antibiotics. In one week of treatment with AZAC 1%, bacterial counts were reduced on the average from approximately 2 X 10(7) to 2 X 10(5) (99%). Silver-zinc-allantoinate cream also demonstrated a wide spectrum of antimicrobial activity. It did not give rise to resistance by the infecting organisms, was nonallergenic, debrided necrotic tissue, and stimulated healthy granulation. Treatment was well tolerated, side effects being limited to a burning sensation in three patients. Most patients cared for themselves at home with minimal interference in their usual daily activities.

    Chronic venous insufficiency is a prevalent disease that frequently leads to development of venous leg ulcers. While a number of evidence-based clinical practice guidelines have been developed that provide guidance for clinicians when caring for patients with chronic venous insufficiency, they lack adequate detail concerning selection and application of compression for prevention and management of venous leg ulcers. In order to address this need, the WOCN Society appointed a task force to develop an algorithm for compression for primary prevention, treatment, and prevention of recurrent venous leg ulcers in persons with chronic venous insufficiency. The task force used findings from a scoping literature review to identify current best evidence needed to support decision points and pathways within the algorithm. In addition, the task force convened a panel of 20 clinicians and researchers with expertise in lower extremity venous disorders in order to establish consensus around pathways and decision points within the algorithm lacking robust evidence. Following initial construction of the algorithm, a second interdisciplinary group of expert clinicians established content validity and provided additional qualitative feedback used to complete final revisions of the algorithm. This article reviews the process used to create this landmark algorithm, including generation of the evidence- and consensus-based statements used in its construction, the various pathways, and rich supplemental materials embedded within the algorithm, and the process used to establish content validity.

    Summary Background Well-tolerated and effective treatments are needed for chronic leg ulcers in sickle cell anaemia. Topical sodium nitrite, a known nitric oxide donor, enhances blood flow in ulcers and has known bacteriostatic effects. We aimed to assess the safety, tolerability, and pharmacokinetics of topical sodium nitrite in patients with sickle cell disease and chronic leg ulcers. Methods We enrolled adult patients from an ambulatory clinic at the National Institutes of Health (Bethesda, MD, USA) with sickle cell anaemia with leg ulcers (with a surface area of 2.5–100 cm2) persisting for at least 4 weeks into a safety and tolerability phase 1 dose-escalation trial of topical sodium nitrite. Increasing concentrations of sodium nitrite cream were applied twice weekly for 4 weeks to one ulcer per patient at five dose levels (0.5%, 1%, 1.5%, 1.8%, and 2%). The primary endpoints were safety and tolerability, with secondary endpoints of pharmacokinetics, blood flow, and wound healing. Pain relief was analysed post hoc. Endpoints were analysed over time for the whole study population and according to dose level. This study is registered with ClinicalTrials.gov, number NCT01316796. Findings Between April 4, 2011, and March 19, 2013, we enrolled 18 adult patients with sickle cell anaemia and leg ulcers into our trial. We assigned three patients into each cohort, and each cohort was treated with a different concentration of sodium nitrite cream (cohort 1: 0.5%, cohort 2: 1.0%, cohort 3: 1.5%, and cohort 4: 2.0%). Patients were not enrolled into the next cohort dose until we were able to establish that no dose-limiting toxicities were observed. An additional six patients were enrolled to cohort 3a: 1.8%, after two patients in cohort 4 had asymptomatic drops in diastolic blood pressure. No grade 3–4 adverse events were observed, and there were no serious adverse events or dose-limiting side-effects. Pharmacokinetic analysis showed that systemic absorption of sodium

    A study has been conducted on the commercially available compression bandages as regards their performance with time. Pressure mapping of these bandages has been done using a fabricated pressure-measuring device on a mannequin leg to see the effect on pressure due to creep, fabric friction and angle of bandaging. The results show that the creep behavior, frictional behavior and the angle of bandaging have a significant effect on the pressure profile generated by the bandages during application. The regression analysis shows that the surface friction restricts the slippage in a multilayer system. Also the diameters of the limb and the amount of stretch given to the bandage during application have definite impact on the bandage pressure. In case of compression garments, washing improves the pressure generated but not to the extent of the pressure of a virgin garment. Comparing the two compression materials i.e. bandage and garment, it is found that the presence of higher percentage of elastomeric material and a highly close construction in case of garment provides better holding power and a more homogeneous pressure distribution.

    Although gastroduodenal ulcers are common in solid organ transplant patients, there are few reports on multiple giant ulcers in the distal ileum and ileocecal valve caused by immunosuppressants Herein, we report on a liver transplant recipient and a renal transplant recipient with multiple large ulcers in the distal ileum and ileocecal valve who rapidly achieved ulcer healing upon withdrawal of sirolimus or tacrolimus and administration of thalidomide. In case 1, a 56-year-old man with primary hepatocellular carcinoma had received a liver transplantation. Tacrolimus combined with sirolimus and prednisolone was used as the anti-rejection regimen. Colonoscopy was performed because of severe abdominal pain and diarrhea at post-operative month 10. Multiple giant ulcers were found at the ileocecal valve and distal ileum. The ulcers healed rapidly with withdrawal of sirolimus and treatment with thalidomide. There was no recurrence during 2 years of follow-up. In case 2, a 34-year-old man with end-stage kidney disease received kidney transplantation and was put on tacrolimus combined with mycophenolate mofetil and prednisolone as the anti-rejection regimen. Twelve weeks after the operation, the patient presented with hematochezia and severe anemia. Colonoscopy revealed multiple large ulcers in the ileocecal valve and distal ileum, with massive accumulation of fresh blood. The bleeding ceased after treatment with intravenous somatostatin and oral thalidomide. Tacrolimus was withdrawn at the same time. Colonoscopy at week 4 of follow-up revealed remarkable healing of the ulcers, and there was no recurrence of bleeding during 1 year of follow-up. No lymphoma, tuberculosis, or infection of cytomegalovirus, Epstein-Barr virus, or fungus was found in either patient. In post-transplantation cases with ulcers in the distal ileum and ileocecal valve, sirolimus or tacrolimus should be considered a possible risk factor, and withdrawing them or switching to another immunosuppressant

    This study investigated the performance of a new gelling fibre dressing containing silver (DURAFIBER™ Ag; Smith & Nephew, Hull, UK) in moderate to highly exuding venous leg ulcers with one or more clinical signs of infection. Fourteen patients with venous leg ulceration of median ulcer duration 12·5 weeks, recruited from three centres in South Africa, received treatment with the new dressing for a maximum of 8 weeks. Multilayer compression bandaging was used for all patients, at the majority of assessments. The objectives of this study were to assess the clinical acceptability of the dressing in terms of the following characteristics: antimicrobial properties, the progress of the wound towards healing, wear time, exudate management, conformability, patient comfort, pain on application, pain on removal and dressing integrity. The new dressing was rated as clinically acceptable for all characteristics, for all 14 patients (100%). It was easy to apply and remove; in 96·8% of removals, the dressing stayed intact on removal and could be removed in one piece. Fifty per cent of the wounds healed within the 8-week study duration; between baseline and final assessment, the median percentage reduction in wound area was 98·2% and the median percentage reduction in devitalised tissue was 78%. Exudate levels and wound pain were significantly improved at final assessment compared to baseline assessment, and an increase in the number of patients with healthy peri-wound skin between baseline and final assessment was observed. A reduction in bioburden and signs of clinical infection and an improvement in quality of life were observed over the 8-week period. The average wear time was 6·4 days. This study supports the use of new dressing in the management of moderately to highly exuding venous leg ulcers with clinical signs of infection. PMID:24602074

    Rats were subjected to tail-cast suspension hypokinesia for 6 days with one leg immobilized in dorsal flexion by casting. Control animals were also tail-casted. The soleus, gastrocnemius and plantaris muscles of uncasted hypokinetic legs were smaller than control muscles. Dorsal flexion prevented atrophy of these muscles and caused the soleus to hypertrophy. The anterior muscles were unaffected by hypokinesia. The smaller size of the soleus of the uncasted leg relative to the dorsal flexed and weight bearing limbs correlated with slower protein synthesis and faster proteolysis. The capacity of this muscle to synthesize glutamine (gln), which carries nitrogenous waste from muscle was also measured. Although tissue homogenates showed higher activities of gln synthetase, the rate of de novo synthesis was not altered in intact muscle but the tissue ratio of gln/glutamate was decreased. Glutamate and ATP were not limiting for gln synthesis, but availability of ammonia may be a limiting factor for this process in hypokinesia.

    The objective of this study was to analyze the application and usefulness of a range of Allevyn trademark hydro-cellular dressings during cicatrisation and in the control of exudation and other various characteristics of chronic lesions in real clinical conditions where patients were treated by primary health care professionals. In this study, 441 patients having chronic wounds, either bed sores or leg ulcers, were studied, health care professionals applied a planned program of measures repeated during 20 dressing changes or until cicatrisation was completed if this happened during this interval. The sample population was comprised of elderly patients, the majority of whom were women whose general health could be classified from medium to poor. These patients suffered from these types of wounds: 63% had bed sores, 27.2% had varicose ulcers and 9.8% had leg ulcers caused by another etiology such as mixed ulcers, arterial ulcers or diabetic foot. On average, these lesions were characterized by an evolutionary period of 6.1 months and had a 30.43 square centimetre surface area at the start of the study. 126 lesions, or 28.8%, cicatrized on average of 47.3 days. Among the 315 lesions which had not cicatrized by the end of 20 dressing changes, 90.5% showed evidence of improvement. During the study these lesions showed a significant reduction in their surface area, as well as a significant improvement at the edges of these lesions and the peri-ulceral skin. The health personnel which carried out the treatment using these dressings gave a very favorable evaluation for their use. At the end of this study, in comparison with other dressings previous used, this study showed that in 43.43% of the cases an Allevyn dressing was deemed better in terms of ease in application, in 51.79% of the cases an Allevyn dressing was better in terms of absorption and in 43.23% of the cases an Allevyn dressing was better during removal.

    2013-01-01

    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

    2010-04-15

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

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

    2008-01-01

    Background: Water-filtered infrared-A (wIRA) is a special form of heat radiation with a high tissue-penetration and with a low thermal burden to the surface of the skin. wIRA is able to improve essential and energetically meaningful factors of wound healing by thermal and non-thermal effects. Aim of the study: prospective study (primarily planned randomised, controlled, blinded, de facto with one exception only one cohort possible) using wIRA in the treatment of patients with recalcitrant chronic venous stasis ulcers of the lower legs with thermographic follow-up. Methods: 10 patients (5 males, 5 females, median age 62 years) with 11 recalcitrant chronic venous stasis ulcers of the lower legs were treated with water-filtered infrared-A and visible light irradiation (wIRA(+VIS), Hydrosun® radiator type 501, 10 mm water cuvette, water-filtered spectrum 550–1400 nm) or visible light irradiation (VIS; only possible in one patient). The uncovered wounds of the patients were irradiated two to five times per week for 30 minutes at a standard distance of 25 cm (approximately 140 mW/cm2 wIRA and approximately 45 mW/cm2 VIS). Treatment continued for a period of up to 2 months (typically until closure or nearly closure of the ulcer). The main variable of interest was “percent change of ulcer size over time” including complete wound closure. Additional variables of interest were thermographic image analysis, patient’s feeling of pain in the wound, amount of pain medication, assessment of the effect of the irradiation (by patient and by clinical investigator), assessment of feeling of the wound area (by patient), assessment of wound healing (by clinical investigator) and assessment of the cosmetic state (by patient and by clinical investigator). For these assessments visual analogue scales (VAS) were used. Results: The study showed a complete or nearly complete healing of lower leg ulcers in 7 patients and a clear reduction of ulcer size in another 2 of 10 patients, a

    We describe a case of proximal small bowel obstruction caused by an occlusive thrombus as a result of bleeding from a duodenal ulcer, which is likely to be stress induced. Initial presentation was confused as a bleeding duodenal ulcer and resultant ileus. Such reports are incredibly rare in the literature and never has one been reported as a result of a stress ulcer. Obstructive symptoms in the acute postoperative patient may be confused for an ileus but mechanical causes must be excluded. The presence of upper gastrointestinal bleeding must not detract from that possibility. Future identification of an occlusive clot on endoscopy that is impossible to circumnavigate may benefit from intraluminal injection of thrombolytic agents to prevent obstruction but this must be weighed with the risk of exacerbating any bleeding. Clearly a risk versus benefit analysis will be necessary on an individual basis. PMID:24960721

Inoculation of thiosulphate citrate bile sucrose (TCBS) agar with tissue material from Porites cylindrica infected with white spot produced colonies of approximately 3 mm diameter consisting of Gram-negative, motile, non-sucrose-fermenting, slightly curved rods with a minimum NaCl requirement of 0.3%. Three of these putative Vibrio sp. isolates were used for infection trials that included different stages of cell growth. Four modes of inoculation and 3 stages of bacterial cell growth were considered for testing Koch's postulates. Stationary phase cells proved more consistently infectious than did exponentially growing or starved cells using a 1-step immersion technique at cell concentrations of 10(4) cells ml(-1). A 1-step immersion technique proved more reliable in producing signs of white spot than did other techniques, such as injection, smearing and 2-step immersion of the inoculum. At inoculum densities >10(4) cells ml(-1) further signs of disease, such as tissue degradation and bleaching, also became evident. At elevated temperatures (>29 degrees C) bleaching remained absent for at least 2 mo from non-inoculated corals serving as controls, but was observed in artificially infected coral fragments. Of the 9 seawater aquaria containing healthy specimens of P. cylindrica, 6 showed signs of white spot 15 d after infection with an isolate tentatively identified as Vibrio sp. Based on 99% similarity of its 16S rRNA gene sequence and selected phenotypical features, this isolate revealed a close relationship to V. natriegens and V. parahaemolyticus.

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

    We report a case of circumferential venous leg ulcer in a rheumatoid arthritis patient. Mesh skin grafting was performed in another hospital, but the graft failed and the patient was referred to our hospital. This ulcer was treated by the combination therapy of a fenestrated-type artificial dermis with negative pressure wound therapy (NPWT) and secondary mesh grafting using our 'grip tape technique'. NPWT was started at -100 mmHg and continued until the formation of dermis-like tissue. A section stained using haematoxylin and eosin and an anti-αSMA (α smooth muscle actin) immunohistological section of the biopsy from dermis-like tissue showed an abundant infiltration of fibroblasts and capillary formation beneath the fenestration of the silicone sheet. Threefold mesh skin grafting was subsequently performed and it was taken up completely. The fenestrated-type artificial dermis in combination with NPWT produced good results without infection in the treatment of complex wounds. In addition, our 'grip tape technique' was useful to apply polyurethane foam to the entire surface of the lower leg.

    Using data from a national wound-specific electronic medical record (WoundExpert, Net Health, Pittsburgh, PA), we compared the effectiveness of a bilayered living cellular construct (BLCC) and an acellular porcine small intestine submucosa collagen dressing (SIS) for the treatment of venous leg ulcer. Data from 1,489 patients with 1,801 refractory venous leg ulcers (as defined by failure to have >40% reduction in size in the 4 weeks prior to treatment) with surface areas between 1 and 150 cm(2) in size, treated between July 2009 and July 2012 at 158 wound care facilities across the US were analyzed. Patient baseline demographics and wound characteristics were comparable between groups. Kaplan-Meier-derived estimates of wound closure for BLCC (1,451 wounds) was significantly greater (p = 0.01, log-rank test) by weeks 12 (31% vs. 26%), 24 (50% vs. 41%), and 36 (61% vs. 46%), respectively, compared with SIS (350 wounds). BLCC treatment reduced the median time to wound closure by 44%, achieving healing 19 weeks sooner (24 vs. 43 weeks, p = 0.01, log-rank test). Treatment with BLCC increased the probability of healing by 29% compared with porcine SIS dressing (hazard ratio = 1.29 [95% confidence interval 1.06, 1.56], p = 0.01).

    Prostaglandins appear to reduce biofilm formation and chronicization of infections, and stimulate a rapid and effective clearance of infecting micro-organisms. We report a case of recovery from methicillin-susceptible Staphylococcus aureus (MSSA) osteomyelitis after multidisciplinary management with antibiotics, anti-thrombotics and prostaglandin E1 (PGE1) vasodilator, in a patient with tibial plateau fracture repaired with internal fixation devices. A 47-year-old HIV-negative male with chronic ulcer on the proximal third of the left leg was admitted to the Orthopaedic Unit of the Orestano Clinic in Palermo, Italy, for suspected osteomyelitis. A biopsy of the skin ulcer and blood cultures were performed and resulted positive for MSSA. Labelled leukocyte scintigraphy confirmed osteomyelitis. No clinical improvement was observed after combined antibiotic treatment with rifampicin plus trimethoprim-sulfamethoxazole. The patient underwent a 4-day therapeutic cycle: PGE1 (alprostadil 60 mg/day IV) combined with nadroparin calcium plus gentamicin, followed by treatment with aminaftone plus sulodexide plus levofloxacin. At discharge, the patient's painful symptoms had completely resolved and the ulcer had cicatrized; recovery from osteomyelitis was confirmed by scintigraphy. This treatment protocol including PGE1 may result in a significant improvement in quality of life and functional status of patients with a reduction in direct and indirect costs and economic benefit for the National Health Service.

    One of the main techniques for recognizing individuals in avian field research is marking birds with plastic and metal leg rings. However, in some species individuals may react negatively to rings, causing leg injuries and, in extreme cases, the loss of a foot or limb. Here, we report problems that arise from ringing and illustrate solutions based on field data from Brown Thornbills (Acanthiza pusilla) (2 populations), Siberian Jays (Perisoreus infaustus) and Purple-crowned Fairy-wrens (Malurus coronatus). We encountered three problems caused by plastic rings: inflammations triggered by material accumulating under the ring (Purple-crowned Fairy-wrens), contact inflammations as a consequence of plastic rings touching the foot or tibio-tarsal joint (Brown Thornbills), and toes or the foot getting trapped in partly unwrapped flat-band colour rings (Siberian Jays). Metal rings caused two problems: the edges of aluminium rings bent inwards if mounted on top of each other (Brown Thornbills), and too small a ring size led to inflammation (Purple-crowned Fairy-wrens). We overcame these problems by changing the ringing technique (using different ring types or larger rings), or using different adhesive. Additionally, we developed and tested a novel, simple technique of gluing plastic rings onto metal rings in Brown Thornbills. A review of studies reporting ring injuries (N = 23) showed that small birds (<55 g body weight) are more prone to leg infections while larger birds (>35 g) tend to get rings stuck over their feet. We give methodological advice on how these problems can be avoided, and suggest a ringing hazard index to compare the impact of ringing in terms of injury on different bird species. Finally, to facilitate improvements in ringing techniques, we encourage online deposition of information regarding ringing injuries of birds at a website hosted by the European Union for Bird Ringing (EURING).

    Infectious keratitis represents a significant cause of ocular morbidity in the United States. The work-up and treatment of presumed infectious keratitis (PIK) has changed in the past two decades. The development of newer topical antibiotics has enabled broad-spectrum antibiotic coverage with good tissue penetration. The majority of PIK cases respond well to this strategy. The small numbers of cases that do not respond to the treatment are the cases that offer a diagnostic and therapeutic challenge. This review will describe different algorithms that can be followed for the successful management of patients with difficult or progressive PIK. These algorithms are based on scientific work and on our empirical clinical experience. The review will also present three different clinical cases of PIK that were managed according to the algorithms presented in this review.

    Venous leg ulcers (VLU) generally have slow healing rates (HR) and frequent recurrence rates (RR). The underlying etiology is venous hypertension. The present observational cohort study was to determine healing and RR in VLU treated with ultrasound-guided foam sclerotherapy (UGFS). One hundred and eighty VLU were treated with polidocanol microfoam monthly under ultrasound control. Median follow-up was 30 months (range: 17-40). One hundred seventy-two (95.6%) ulcers healed during the study. The overall twenty-four week HR was 79.4% and was significantly higher (95.1%) in patients with isolated great saphenous vein incompetence than in those with great saphenous vein plus perforator (91.7%) or exclusive perforator incompetence (78.9%) (p < 0.01). Patients without deep vein incompetence had a significantly higher 6-month HR (89.8%) than those with (67.4%) (p < 0.01). Multivariate analysis identified the following independent risk factors: chronicity > 12 months (OR 7.69), area > 6 cm(2) (OR 4.24), lipodermatoesclerosis (OR 12.22), history of > 3 previous ulcers (OR 5.57) and history of deep vein thrombosis (OR 6.18). One, two and three year ulcer RR were 8.1%, 14.9%, and 20.8%, respectively. Isolated perforator incompetence and previous history of venous surgery were significantly (p = 0.03) associated with a higher RR. VLU treated with microfoam sclerotherapy are associated with high HR and low mid-term RR.

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

    Serratia marcescens is an unusual cause of severe skin infection initially described in immunocompromised patients. We report a case of necrotizing cellulitis of the leg caused by S marcescens in a 68-year-old woman with diabetes mellitus and a history of chronic lymphoedema of the leg. We reviewed the literature and found 49 cases of severe skin infections from S marcescens that included 20 cases of necrotizing fasciitis (NF) as well as 29 cases of severe skin infections without NF (non-NF cases). Patients were immunocompromised in 59% to 70% of cases. The mortality rate was high in NF cases (60%) versus non-NF cases (3%). Surgery was required in 95% of NF cases and in 24% of non-NF cases. The other clinical manifestations of S marcescens skin infection reported in the literature included disseminated papular eruptions in patients infected with human immunodeficiency virus with folliculitis on the trunk. Serratia marcescens is naturally resistant to amoxicillin alone and amoxicillin associated with clavulanic acid. Broad-spectrum antibiotics are indicated to treat S marcescens skin infections, and surgery should be promptly considered in cases of severe skin infections if appropriate antibiotic therapy does not lead to rapid improvement.

    Gastrointestinal (GI) haemorrhage is a common surgical emergency accounting for approximately 1% of acute hospital admissions. Lower GI bleed is less common and less severe than upper GI bleed and is usually caused by diverticulosis, neoplasms, angiodysplasia and inflammatory bowel disease. A 51-year-old man presented with massive lower GI bleed. He had no history of tuberculosis. He underwent colonoscopy and an isolated caecal ulcer was noted. Segmental ileocaecal resection was performed and no specific cause was identifiable on histopathology. PCR was performed on this specimen and it was positive for Mycobacterium tuberculosis. This case reports the unusual presentation of tuberculosis as solitary caecal ulcer with massive lower GI bleed and highlights the role of PCR as an adjuvant diagnostic tool for its diagnosis when characteristic histopathological findings are absent.

    Retrograde venous perfusions (RVP) of antibiotics were proven to be therapeutically more effective than systemic venous infusions (SVI) in patients with infected diabetic neuropathic plantar ulcers (DNPU: no additional macronagiopathy of leg arteries). In order to study some pharmakokinetic features of RVP application paratibial tissue levels of Netilmycin (NL; from suction blister fluid) and cubital venous NL were compared under each SVI and RVP therapy in 8 patients with DNPU. Tissue (11.6 +/- 6.4 micrograms/l) were significantly higher (p < 0.001) an within the therapeutic range after RVP (SVI: 4.31 +/- 1.68). In ulcer transsudate (RVP only; n = 4) NL mounted to 36.4 +/- 11.6 microgram/ml. Peak and base NL in cubital blood were within the normal range for both SVI and RVP (no significant difference). The date indicate that RVP is superior to SVI application of Netilmycin (and probably other antibiotics) as surmounting the damaged microcirculation in DNPU to achieve effective drug levels in the target tissue.

  9. Management of gastroduodenal ulcers caused by non-steroidal anti-inflammatory drugs.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are a major cause of morbidity and mortality, probably resulting in the death of 1200 patients per annum in the UK. The main mechanism of toxicity involves an inhibition of prostaglandin synthesis that results in mucosal erosion as a result of the abrogation of defence mechanisms. However, acid peptic attack can deepen this initial injury. Thus, logical treatments include prostaglandin analogues as 'replacement therapy', acid suppression, enteric coating to avoid topical effects and the use of safer NSAIDs, including those that have little or no effect on gastric mucosal prostaglandin synthesis. There is less logic to the strategy of Helicobacter pylori (H. pylori) eradication, and the status of this approach is controversial. Overall, proton pump inhibitors have the best profile of efficacy and side-effects for the healing and prevention of NSAID-associated ulcers. Misoprostol is also effective and appears to be superior to proton pump inhibitors for superficial erosive injury. Early indications are that selective inhibitors of the inducible cyclooxygenase-2 enzyme have little or no effect in causing ulcers. Growing experience with these agents will probably revolutionize the management of patients with arthritic conditions. However, the increasing use of low-dose aspirin for cardiovascular prophylaxis means that gastroenterologists will have to continue to grapple with the problems of NSAID-associated ulcers for some time to come.

    Although lipomas are among the most frequent tumors in the human body, their presentation in the oral cavity is not common. Oral cavity lipomas usually show a slow painless and assymptomatic growing. When these tumors reach big sizes, they can cause compressive symptons and deformities. In this paper we present the case of a patient in whom oral lipoma was the final finding in the differential diagnosis of a chronic mucosal ulcer. CT scan and MRI images and microscopical examination after fine-needle aspiration were the clue for the final diagnosis. The surgical excision of the tumor was the basis for the healing of the ulcer. We also review the most relevant and recent literature about clinic, diagnosis and treatment for these tumors.

    Chronic venous ulceration (CVU) is the major cause of chronic wounds of lower extremities, and is a part of the complex of chronic venous disease. Previous studies have hypothesised that several thrombophilic factors, such as hyperhomocysteinaemia (HHcy), may be associated with chronic venous ulcers. In this study, we evaluated the prevalence of HHcy in patients with venous leg ulcers and the effect of folic acid therapy on wound healing. Eighty-seven patients with venous leg ulcers were enrolled in this study to calculate the prevalence of HHcy in this population. All patients underwent basic treatment for venous ulcer (compression therapy ± surgical procedures). Patients with HHcy (group A) received basic treatment and administered folic acid (1·2 mg/day for 12 months) and patients without HHcy (group B) received only basic treatment. Healing was assessed by means of computerised planimetry analysis. The prevalence of HHcy among patients with chronic venous ulcer enrolled in this study was 62·06%. Healing rate was significantly higher (P < 0·05) in group A patients (78·75%) compared with group B patients (63·33%). This study suggests a close association, statistically significant, between HHcy and CVU. Homocysteine-lowering therapy with folic acid seems to expedite wound healing. Despite these aspects, the exact molecular mechanisms between homocysteine and CVU have not been clearly defined and further studies are needed.

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

    The risk of colorectal cancer for any patient with ulcerative colitis is known to be elevated, and is estimated to be 2% after 10 years, 8% after 20 years and 18% after 30 years of disease. Risk factors for cancer include extent and duration of ulcerative colitis, primary sclerosing cholangitis, a family history of sporadic colorectal cancer, severity of histologic bowel inflammation, and in some studies, young age at onset of colitis. In this review, the authors discuss recent epidemiological trends and causes for the observed changes. Population-based studies published within the past 5 years suggest that this risk has decreased over time, despite the low frequency of colectomies. The crude annual incidence rate of colorectal cancer in ulcerative colitis ranges from approximately 0.06% to 0.16% with a relative risk of 1.0-2.75. The exact mechanism for this change is unknown; it may partly be explained by the more widespread use of maintenance therapy and surveillance colonoscopy.

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

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

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

    Clinical diagnosis of infection in chronic wounds is currently limited to subjective clinical signs and culture-based methods that underestimate the complexity of wound microbial bioburden as revealed by DNA-based microbial identification methods. Here, we use 16S rRNA next generation sequencing and quantitative polymerase chain reaction to characterize weekly changes in bacterial load, community structure, and diversity associated with a chronic venous leg ulcer over the 15-week course of treatment and healing. Our DNA-based methods and detailed sampling scheme reveal that the bacterial bioburden of the wound is unexpectedly dynamic, including changes in the bacterial load and community structure that correlate with wound expansion, antibiotic therapy, and healing. We demonstrate that these multidimensional changes in bacterial bioburden can be summarized using swabs taken prior to debridement, and therefore, can be more easily collected serially than debridement or biopsy samples. Overall, this case illustrates the importance of detailed clinical indicators and longitudinal sampling to determine the pathogenic significance of chronic wound microbial dynamics and guide best use of antimicrobials for improvement of healing outcomes.

    Background MUC2 mucin produced by intestinal goblet cells is the major component of the intestinal mucus barrier. The inflammatory bowel disease ulcerative colitis is characterized by depleted goblet cells and a reduced mucus layer, but the aetiology remains obscure. In this study we used random mutagenesis to produce two murine models of inflammatory bowel disease, characterised the basis and nature of the inflammation in these mice, and compared the pathology with human ulcerative colitis. Methods and Findings By murine N-ethyl-N-nitrosourea mutagenesis we identified two distinct noncomplementing missense mutations in Muc2 causing an ulcerative colitis-like phenotype. 100% of mice of both strains developed mild spontaneous distal intestinal inflammation by 6 wk (histological colitis scores versus wild-type mice, p < 0.01) and chronic diarrhoea. Monitoring over 300 mice of each strain demonstrated that 25% and 40% of each strain, respectively, developed severe clinical signs of colitis by age 1 y. Mutant mice showed aberrant Muc2 biosynthesis, less stored mucin in goblet cells, a diminished mucus barrier, and increased susceptibility to colitis induced by a luminal toxin. Enhanced local production of IL-1β, TNF-α, and IFN-γ was seen in the distal colon, and intestinal permeability increased 2-fold. The number of leukocytes within mesenteric lymph nodes increased 5-fold and leukocytes cultured in vitro produced more Th1 and Th2 cytokines (IFN-γ, TNF-α, and IL-13). This pathology was accompanied by accumulation of the Muc2 precursor and ultrastructural and biochemical evidence of endoplasmic reticulum (ER) stress in goblet cells, activation of the unfolded protein response, and altered intestinal expression of genes involved in ER stress, inflammation, apoptosis, and wound repair. Expression of mutated Muc2 oligomerisation domains in vitro demonstrated that aberrant Muc2 oligomerisation underlies the ER stress. In human ulcerative colitis we demonstrate similar

    Chronic skin ulcers in the lower legs, feet, toes, and digits are sometimes idiopathic and intractable, and occasionally cause limb gangrene. Although there are many conditions that can cause chronic limb ulcers, including primary or secondary vascular diseases, the reasons why specific patients develop chronic skin ulcers have still remained unclear.(1) Antiphospholipid syndrome (APS) is an acquired coagulation disorder occurring as vascular thrombosis or pregnancy complications.

    Structure-activity relationships were qualitatively and quantitatively examined for 56 chemicals (e.g., derivatives of propionitrile, acrylonitrile and cysteamine) which caused duodenal ulcer and/or adrenocortical necrosis in rats. For the first time the duodenal ulcerogenic property of numerous chemicals has been studied in a rational and predictive manner. Ulcerogenic activity was most intense in the carbonitriles attached to two or three carbon backbones and diminished by shortening, lengthening, branching, unsaturating, halogenating or hydroxylating the carbon chains. Different modes of action are implied. Adrenocorticolytic potency was associated with unsaturation of the carbon chain and substitution of the nitrile by thiol or amine radicals. An action of these chemicals on the central nervous system has been suggested.

    A biologically active human skin allograft, currently distributed under the brand name TheraSkin(®), was examined for safety and efficacy in the treatment of venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). The objective was to determine if TheraSkin could serve as a safe and effective alternative to bioengineered skin substitutes such as Apligraf(®) and Dermagraft(®). The authors conducted a retrospective study of 214 consecutive patients seen at the Inova Wound Center (Mt Vernon, Virginia), with either a DFU or a VLU. After excluding patients who did not meet the study criteria, the final eligible cohort consisted of 188 subjects, with 134 VLUs and 54 DFUs. Multivariate logistic regression was used to evaluate the relationship between baseline wound size and the proportion of healed wounds after 12 and 20 weeks from initial allograft application. The authors found that by the 12th week, DFUs closed 60.38% of the time and VLUs closed 60.77% of the time. After 20 weeks, the number of closed DFUs increased to 74.1% and the number of VLUs increased to 74.6%. The mean wound size in the DFU group was 6.2 cm(2) (±11.8) and 11.8 cm(2) (±22.5) in the VLU group. The mean number of TheraSkin allografts required ranged from 1 to 8, with an average of 2.03 (±1.47) at the 12-week point and an average of 3.23 (±2.77) at the 20-week point. Multivariate logistic regression was used to calculate the odds of wound healing by week 12 and week 20 in each group. The authors also analyzed adverse events and found TheraSkin to be noncontributory to any adverse events, verifying the safety of TheraSkin in this study population. In this study, TheraSkin has been shown to be highly effective for the treatment of both VLUs and DFUs with an acceptable safety profile.

  5. Inflammation in chronic venous ulcers.

    Chronic venous ulcers (CVUs) occur in approximately 1% of the general population. Risk factors for chronic venous disease (CVD) include heredity, age, female sex and obesity. Although not restricted to the elderly, the prevalence of CVD, especially leg ulcers, increases with age. CVD has a considerable impact on health-care resources. It has been estimated that venous ulcers cause the loss of approximately two million working days and incur treatment costs of approximately $3 billion per year in the USA. Overall, CVD has been estimated to account for 1-3% of the total health-care budgets in countries with developed health-care systems. The pathophysiology of dermal abnormalities in CVU is reflective of a complex interplay that involves sustained venous hypertension, inflammation, changes in microcirculation, cytokine and matrix metalloproteinase (MMP) activation, resulting in altered cellular function and delayed wound healing.

    D-penicillamine has long been used in the management of rheumatic diseases due to the effects on inhibition of collagen synthesis. Herein, we report a severe case of esophageal ulcer causing a tight stricture extending through the distal esophagus despite the long-term D-penicillamine treatment in a patient with Wilson's disease. D-penicillamine would theoretically be expected to contribute to the healing of an esophageal ulcer. However, the drug failed to have a favorable outcome, which is notable and worth reporting.

    We have reviewed all endoscopies performed in our hospital between 1977 and 1986. During that period, 1337 endoscopies were performed to identify bleeding from peptic ulcers. Excluded were cases in which a predisposing factor was found, such as the use of ulcerogenic drugs. Also excluded were chronic or critically ill patients. The remaining 540 cases were reviewed. In 447 of those cases, the bleeding lesion was a duodenal ulcer, whereas, in 93 cases, a gastric ulcer was found (a ratio of 5:1). The seasonal variation in the incidence of bleeding from peptic ulcers was evaluated. We found a significant difference in bleeding in the cold and hot seasons, the incidence being significantly greater during the cold season (November until February). A similar pattern was found for bleeding from both duodenal and gastric ulcers.

    Perioperative treatment of several rats in our facility with ketoprofen (5 mg/kg SC) resulted in blood loss, peritonitis, and death within a day to a little more than a week after surgery that was not related to the gastrointestinal tract. Published reports have established the 5-mg/kg dose as safe and effective for rats. Because ketoprofen is a nonselective nonsteroidal antiinflammatory drug that can damage the gastrointestinal tract, the putative diagnosis for these morbidities and mortalities was gastrointestinal toxicity caused by ketoprofen (5 mg/kg). We conducted a prospective study evaluating the effect of this therapeutic dose of ketoprofen on the rat gastrointestinal tract within 24 h. Ketoprofen (5 mg/kg SC) was administered to one group of rats that then received gas anesthesia for 30 min and to another group without subsequent anesthesia. A third group was injected with saline followed by 30 min of gas anesthesia. Our primary hypothesis was that noteworthy gastrointestinal bleeding and lesions would occur in both groups treated with ketoprofen but not in rats that received saline and anesthesia. Our results showed marked gastrointestinal bleeding, erosions, and small intestinal ulcers in the ketoprofen-treated rats and minimal damages in the saline-treated group. The combination of ketoprofen and anesthesia resulted in worse clinical signs than did ketoprofen alone. We conclude that a single 5-mg/kg dose of ketoprofen causes acute mucosal damage to the rat small intestine.

    Patient: Female, 51 Final Diagnosis: Cameron’s ulcer Symptoms: — Medication: — Clinical Procedure: Endoscopy Specialty: Gastroenterology and Hepatology Objective: Rare co-existance of disease or pathology Background: Cameron lesions are linear gastric erosions on the mucosal folds at the diaphragmatic impressions found in patients with large hiatal hernias. While usually asymptomatic, hiatal hernias can result in serious sequelae, as this case report will clearly illustrate. Cameron lesions are clinically significant because of their ability to cause significant acute, chronic, or obscure gastrointestinal bleeding, often requiring blood transfusions. Case Report: In this report, we present the case of a 51-year-old white woman who originally presented to the Emergency Department with complaints of a runny nose, dry cough, generalized weakness, and muscle cramping ascribed to a viral infection. However, closer examination revealed substantial pallor with pale conjunctiva prompting further workup that revealed substantial anaemia. Upon further inquiry of her past medical history, she revealed the need for previous blood transfusions, and meticulous review of her medical record indicated a previous diagnosis of hiatal hernia with the presence of Cameron lesions based on esophagogastroduodenoscopy 2 years prior. Conclusions: This case emphasizes the need for a high index of suspicion for Cameron lesions as a causative agent of substantial blood loss in patients with hiatal hernias after other common causes of gastrointestinal bleeding have been ruled out.

    A 66-year-old Japanese male with a history of a rectal ulcer and rectovesical fistula following brachytherapy and radiotherapy for prostate cancer, who had undergone colostomy and vesicotomy presented with a painful peristomal ulcer of approximately 5 x 2.5cm adjacent to the direction of 6 o'clock of the stoma in his left lower abdomen. Although he was admitted to be treated with intravenous antibiotics and topical debridement, the ulcer was rapidly increasing. In the laboratory findings, WBC was 12,400/μL, CRP was 16.9 mg/dL, ESR was 105mm in the first hour. Contrast enhanced CT images showed a wide high density area of skin and subcutaneous tissue around the stoma and dillitation of the transverse and descending colon. Colonoscopy showed furred profound ulcers in the rectum. A biopsy from the ulcer floor submitted to histopathology showed necrotic tissue with a mixed inflammatory infiltrates mainly composed of neutrophils and lymphocytes in the dermis. We suspected pyoderma gangrenosum with an inflammatory bowel disease in the beginning. Although he was started on oral prednisolone 60 mg daily, the ulcer did not respond to treatment. Additional methylprednisolone pulse therapy, intravenous cyclosporine and granulocytapheresis were also ineffective. A biopsy specimen from the skin ulcer margin showed erythrophagocytosis by trophozoites of amebae which were identified on PAS stained slides. The PCR method and stool examination showed positive for Entamoeba histolytica (E. histolytica), but serum antibodies were negative. Within two weeks of treatment with oral metronidazole 2,250 mg/day and topical metronidazole ointment, resolution of the ulcer was observed, then the prednisolone dosage was tapered. A split-thickness skin graft was used to cover the ulcer with a successful result. Even though we originally misdiagnosed this case, we finally reached a diagnosis of amebiasis. It is important to take account of amebiasis in the differential diagnosis of intractable

    Diffusional kurtosis MRI (DKI) quantifies the deviation of water diffusion from a Gaussian distribution. We investigated the influence of passive elongation and shortening of the lower leg muscles on the DKI parameters D (diffusion coefficient) and K (kurtosis). After approval by the local ethics committee, eight healthy volunteers (age, 29.1 ± 2.9 years) underwent MRI of the lower leg at 3 T. Diffusion-weighted images were acquired with 10 different b values at three ankle positions (passive dorsiflexion 10°, neutral position 0°, passive plantar flexion 40°). Parametrical maps of D and K were obtained by voxel-wise fitting of the signal intensities using a non-linear Levenberg-Marquardt algorithm. D and K were measured in the tibialis anterior, medial and lateral gastrocnemius, and soleus muscles. In the neutral position, D and K values were in the range between 1.66-1.79 × 10(-3) mm(2) /s and 0.21-0.39, respectively. D and K increased with passive shortening, and decreased with passive elongation, which could also be illustrated on the parametrical maps. In dorsiflexion, D (p < 0.01) and K (p = 0.036) were higher in the tibialis anterior than in the medial gastrocnemius. In plantar flexion, the opposite was found for K (p = 0.035). DKI parameters in the lower leg muscles are significantly influenced by the ankle joint position, indicating that the diffusion of water molecules in skeletal muscle deviates from a Gaussian distribution depending on muscle tonus.

    One of the main techniques for recognizing individuals in avian field research is marking birds with plastic and metal leg rings. However, in some species individuals may react negatively to rings, causing leg injuries and, in extreme cases, the loss of a foot or limb. Here, we report problems that arise from ringing and illustrate solutions based on field data from Brown Thornbills (Acanthiza pusilla) (2 populations), Siberian Jays (Perisoreus infaustus) and Purple-crowned Fairy-wrens (Malurus coronatus). We encountered three problems caused by plastic rings: inflammations triggered by material accumulating under the ring (Purple-crowned Fairy-wrens), contact inflammations as a consequence of plastic rings touching the foot or tibio-tarsal joint (Brown Thornbills), and toes or the foot getting trapped in partly unwrapped flat-band colour rings (Siberian Jays). Metal rings caused two problems: the edges of aluminium rings bent inwards if mounted on top of each other (Brown Thornbills), and too small a ring size led to inflammation (Purple-crowned Fairy-wrens). We overcame these problems by changing the ringing technique (using different ring types or larger rings), or using different adhesive. Additionally, we developed and tested a novel, simple technique of gluing plastic rings onto metal rings in Brown Thornbills. A review of studies reporting ring injuries (N = 23) showed that small birds (<55 g body weight) are more prone to leg infections while larger birds (>35 g) tend to get rings stuck over their feet. We give methodological advice on how these problems can be avoided, and suggest a ringing hazard index to compare the impact of ringing in terms of injury on different bird species. Finally, to facilitate improvements in ringing techniques, we encourage online deposition of information regarding ringing injuries of birds at a website hosted by the European Union for Bird Ringing (EURING).

    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 beta-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-avidin-peroxidase 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.

    2014-01-01

    Painful legs and moving toes syndrome is rare. It is predominantly diagnosed in middle-aged adults following a history of spinal cord surgery or trauma. The syndrome consists of abnormal repetitive movements, most commonly in the lower extremities, accompanied by pain in the affected limb. Pain usually precedes the movements. We report a case in a young patient that we believe was induced by the intake of a low-potency neuroleptic, which was prescribed to him for anxiety. The patient was treated with carbamazepine with mild relief of pain and later on with botulinum injection, which significantly reduced the movements and mildly improved the pain. After stopping the treatment, the beneficial effect lasted for about 3 months after which his condition gradually returned to its initial state. PMID:25535220

    2007-01-01

    Skin breakdown lesions (SBLs) of the legs are common in spinal cord injury (SCI). It is assumed that the cause is deficient sensitivity and immobility of the limbs, which result in areas subjected to prolonged pressures. However, poor circulation may also be a significant factor. Indeed, strong reasons suggest that small vessel circulation is decreased in SCI because these patients have increased arteriosclerotic risk factors. Patients in the SCI population have advanced age, are sedentary, often have abnormal carbohydrate and lipid metabolism, and many use tobacco products. Total blood flow (TBF) to the legs and skin blood flows (SBFs) to 4 areas of the feet were measured simultaneously by duplex Doppler sonography and laser Doppler flowmetry in 10 healthy control and 10 chronic subjects with SCI when supine and during 30 minutes in a wheelchair. The average supine control TBF was 540 mL/minute, but greatly reduced between 24-76 mL/minute in 4 of the subjects. During sitting, the average TBF fell by 41% in the controls and increased by 6% in SCI. Nonetheless, in all control and SCI subjects the average sitting SBFs were severely decreased in all areas between 53-75%, similar to results found by others elsewhere in the foreleg. Ischemia of the skin and underlying muscles is important as a cause for the poor healing of SBLs in persons with SCI who daily spend many hours in a wheelchair.

    One of the major symptoms when women are wearing high heels for a long time is leg swelling. The purpose of this study was to compare the effect of manual lymph drainage with ultrasound therapy. The forty-five healthy women of twenties were participated in this study and divided randomly into three groups; manual lymph drainage group (n=15), ultrasound therapy group (n=15) and control group (n=15). Swelling was measured before wearing the high heels (10 cm-height), after one-hour of wearing the high heels, wearing the high heels of one-hour after the intervention of 15 minutes. Also swelling was calculated by using a tape measure, volumeter and body composition analyzer. Statistical analysis of the comparison between the three groups was performed by one-way ANOVA. Also comparison to the mean value in swelling according to the time was performed by repeated measure ANOVA. As the result of this study, a significant changes have emerged within each of manual lymph drainage, ultrasound therapy and control group (p< 0.05). However, there were no significant differences between each group (p> 0.05). But the mean value of manual lymph drainage group showed the tendency of fast recovering before causing swelling. Therefore, we consider that the clinical treatment of manual lymph drainage and ongoing studies will be made since manual lymph drainage is very effective in releasing the leg swelling caused by wearing high heels and standing for a long time at work.

    Chronic foot and leg ulcers are a common health problem worldwide. A mainstay of chronic ulcer therapy is sharp mechanical wound debridement requiring potent analgesia. In this prospective, controlled, single-centre, crossover design study, patients were assigned to either the administration of topical analgesia with 5% lidocaine/prilocaine cream or the inhalation of an analgesic 50% N2 O/O2 gas premix. Primary outcome parameter was level of pain at maximum wound depth during debridement as measured by a visual analogue scale. Secondary outcomes included level of pain after debridement, overall duration of treatment session, duration and completeness of debridement, and the patient's subjective perception of analgesic quality during debridement. Pain level increased from 0·60/0·94 (first/second debridement; baseline) to 1·76/2·50 (debridement) with 5% lidocaine/prilocaine and from 1·00/1·35 (baseline) to 3·95/3·29 (debridement) with 50% N2 O/O2 gas premix. Patient satisfaction was 90·48%/94·44% (first/second debridement) with topical 5% lidocaine/prilocaine analgesia and 90·48%/76·47% with the inhalation of 50% N2 O/O2 gas premix. Debridement was completed in a significantly higher percentage of 85·71%/88·89% (first/second debridement) with 5% lidocaine/prilocaine than with 50% N2 O/O2 gas premix (42·86%/58·82%) (odds ratio 6·7; P = 0·001). This study provides sound evidence that analgesia with topically administered 5% lidocaine/prilocaine cream is superior to the use of inhaled 50% N2 O/O2 gas premix in chronic leg ulcer debridement.

    We present a patient with unilateral, spontaneous, late leg swelling that developed 4 years after total hip arthroplasty. The etiology was the compression of the internal iliac vein by a voluminous iliopsoas bursitis caused by polyethylene debris. The expansive lesion was detected by ultrasound, arthrography, and magnetic resonance imaging. An ultrasound-guided aspiration provided transient relief of the patient's symptoms. The patient later required surgical excision through an abdominal approach. A second recurrence was detected and treated with revision surgery. We present the diagnosis and the treatment of this rare cause of late, unilateral leg swelling after total hip arthroplasty together with a review of the literature.

    The authors present the management of a young female patient who presented with longstanding bilateral calf muscle hypertrophy, with no known cause. Taking into account the patient's wishes and the fact that the hypertrophy was mainly located in the posteromedial compartment, we chose to carry out a subtotal bilateral resection of medial gastrocnemius muscles. This procedure was performed with an harmonic scalpel, permitting a excellent cosmetic result while avoiding complications or functional impairment. After a reviewing of the commonly used techniques, the authors discuss the chosen surgical approach taking into account its clinical particularity.

    Epizootic ulcerative syndrome (EUS) caused by the oomycete Aphanomyces invadans is an invasive, opportunistic disease of both freshwater and estuarine fishes. Originally documented as the cause of mycotic granulomatosis of ornamental fishes in Japan and as the cause of EUS of fishes in southeast Asia and Australia, this pathogen is also present in estuaries and freshwater bodies of the Atlantic and gulf coasts of the USA. We describe a mass mortality event of 343 captive juvenile bullseye snakehead Channa marulius collected from freshwater canals in Miami-Dade County, Florida. Clinical signs appeared within the first 2 d of captivity and included petechiae, ulceration, erratic swimming, and inappetence. Histological examination revealed hyphae invading from the skin lesions deep into the musculature and internal organs. Species identification was confirmed using a species-specific PCR assay. Despite therapeutic attempts, 100% mortality occurred. This represents the first documented case of EUS in bullseye snakehead fish collected from waters in the USA. Future investigation of the distribution and prevalence of A. invadans within the bullseye snakehead range in south Florida may give insight into this pathogen-host system.

    This study was carried out to assess the efficacy and tolerability of the topical application of an aqueous extract of Triticum vulgare (TV) in different vehicles (cream, impregnated gauzes, foam, hydrogel, and dressing gel) for the treatment of venous lower leg ulcers. 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.

    Corynosoma is a parasite that can normally be found in the intestinal tract of fish-eating mammals, particularly in seals and birds. The present case proposed that Corynosoma could attain full maturity in the human intestine. A 70-year-old female complained of abdominal pain. A computed tomography (CT) scan revealed a swelling of the intraperitoneal lymph nodes with no responsible lesion. Video capsule endoscopy and double-balloon endoscopy detected several ulcerations and one parasite in the ileum, which was tightly attached at the bottom of the ulcerations. The parasite was cylindrical and measured approximately 10 mm (long) x 3 mm (wide). Pathologically, the worm had a four-layered body wall and contained embryonated eggs. The sequences of the parasite-derived nuclear ribosomal DNA fragment and mitochondrial DNA fragment of cox1 were almost identical to those of Corynosoma validum. The patient's abdominal pain immediately improved after the administration of pyrantel pamoate (1,500 mg). Corynosoma was possibly the responsible disease in a patient who complained of abdominal pain and in whom no responsible lesion was detected by CT, gastroduodenoscopy or colonoscopy. Examinations of the small intestines should be aggressively performed in such cases.

    Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis often misdiagnosed. It is uncommon in infants and children accounting for 4% of cases. A one-year-old male in paediatric ICU ventilated for bronchopneumonia was referred with ulcerated areas on his neck and axilla corresponding to sites of recent removal of central and arterial lines. Examination revealed areas of deep ulceration with violaceous undermined borders in keeping with PG. This was supported by a skin biopsy showing a neutrophilic infiltrate in the deeper dermis. Topical clobetasol propionate was commenced and a dramatic improvement within 24 hours noted. Blood results showed a leucocytosis of 29.7; a differential WCC showed toxic granulation in neutrophils with myeloid left shift; immunoglobulins showed elevated IgG 23 and IgA 4.86. The elevated WCC made us consider a leukaemic trigger; however, they settled with treatment of the underlying infection. PG in children is more likely to have an atypical distribution involving the head and neck (26.6%) or buttocks (15%). An interesting feature in this case is the presence of pathergy, a term used to describe the induction or exacerbation of PG at sites of iatrogenic or incidental trauma. It is seen in 31% of patients with PG. PMID:27738542

  10. Transient Willis-Ekbom's disease (restless legs syndrome) during pregnancy may be caused by estradiol-mediated dopamine overmodulation.

    Willis-Ekbom's disease (WED), formerly called restless legs syndrome, is more common in pregnant than in non-pregnant women, implying that the physiological and biochemical changes during pregnancy influence its development. During pregnancy, many hormone levels undergo significant changes, and some hormones significantly increase in activity and can interfere with other hormones. For example, the steroid hormone estradiol interferes with the neuroendocrine hormone dopamine. During pregnancy, the activity of the thyroid axis is enhanced to meet the increased demand for thyroid hormones during this state. Dopamine is a neuroendocrine hormone that diminishes the levels of thyrotropin and consequently of thyroxine, and one of the roles of the dopaminergic system is to counteract the activity of thyroid hormones. When the activity of dopamine is not sufficient to modulate thyroid hormones, WED may occur. Robust evidence in the medical literature suggests that an imbalance between thyroid hormones and the dopaminergic system underpins WED pathophysiology. In this article, we present evidence that this imbalance may also mediate transient WED during pregnancy. It is possible that the main hormonal alteration responsible for transient WED of pregnancy is the excessive modulation of dopamine release in the pituitary stalk by estradiol. The reduced quantities of dopamine then cause decreased modulation of thyrotropin, leading to enhanced thyroid axis activity and subsequent WED symptoms. Iron deficiency may also be a predisposing factor for WED during pregnancy, as it can both diminish dopamine and increase thyroid hormone.

    A 36-year-old man with a 5-year history of untreated human immunodeficiency virus (HIV) infection had odynophagia for 14 days. Fifteen days earlier, he had begun taking trimethoprim-sulphamethoxazole and combination antiretroviral therapy that included lamivudine, zidovudine, and nelfinavir. He had no history of opportunistic infection. The CD4 lymphocyte count was 67/microL and HIV-RNA level was 359,396 copies/mL. Esophagogastroduodenoscopy revealed a large, well-circumscribed esophageal ulceration 31 cm from the incisors. Histopathologic examination of esophageal biopsy specimens showed cytopathic changes diagnostic of cytomegalovirus (CMV). In situ DNA hybridization was positive for CMV. While combination antiretroviral therapy was continued, the esophageal symptoms resolved within 4 days of endoscopy without specific therapy for CMV. Follow-up endoscopy 4 weeks later revealed a normal-appearing esophagus, and the patient has remained symptom-free for 10 months.

    Lupus vulgaris (LV), is a chronic and progressive form of secondary cutaneous tuberculosis. In India, it is commonly seen over buttocks, thighs, and legs whereas involvement of nose is quite rare. Ulcerative variant particularly over nose causes destruction of cartilage, leading to irreversible deformities and contracture. High-index of suspicion is required for early diagnosis and prevention of cosmetic deformity. A case of LV over nose in a young male with ulceration is reported who responded well to anti-tubercular therapy, but left with scarring of nose, which could have been prevented if adequate awareness regarding extra-pulmonary cases would have been practiced.

    Acute genital ulcers, also known as acute vulvar ulcers, ulcus vulvae acutum or Lipschütz ulcers, refer to an ulceration of the vulva or lower vagina of non-venereal origin that usually presents in young women, predominantly virgins. Although its incidence is unknown, it seems a rare entity, with few cases reported in the literature. Their aetiology and pathogenesis are still unknown. The disease is characterised by an acute onset of flu-like symptoms with single or multiple painful ulcers on the vulva. Diagnosis is mainly clinical, after exclusion of other causes of vulvar ulcers. The treatment is mainly symptomatic, with spontaneous resolution in 2 weeks and without recurrences in most cases. We present a case report of a 13-year-old girl with two episodes of acute ulcers that fit the clinical criteria for Lipschütz ulcers. PMID:24473429

    Pain management is extremely important in day surgery, and it is one of the limiting factors for this type of procedures. Locoregional anesthesia is strongly recommended for day surgery; nevertheless, it could be very difficult to localize nerve position especially in obese patients. Furthermore, a complete nerve blockade could result in a delayed discharge. We present a case of analgesic ultrasound-guided block of tibial and common peroneal nerves in the popliteal fossa without any motor function involvement in an obese patient undergoing debridement of an infected lower limb ulcer; all previous attempts of surgical debridement in day surgery with topical anesthetics had failed because of discomfort due to pain. Our aim was to ensure an optimal degree of analgesia and, at the same time, to save motor function in order to make early discharge possible. We used 15 mL ropivacaine 0.375% to obtain a differential block, taking advantage of sensitive fibers selectivity of ropivacaine. Surgical debridement was performed successfully. Our peripheral blockade was able to provide significantly prolonged analgesia without motor block that guaranteed a safe and early discharge according to the Post Anesthetic Discharge Scoring System. The satisfaction expressed by the patient and her comfort during the procedure support the choice of this approach for intractable painful ulcers of lower limb.

    The present study describes a case of leg lymphedema due to iliopectineal bursitis associated with rheumatoid arthritis (RA), which was satisfactorily controlled by surgery and combination therapy with methotrexate (MTX) and tacrolimus. A 68-year-old male, who had a six-year history of RA, developed an iliopectineal bursa associated with destruction of the hip joint. The mass gradually increased in size, and there was swelling in his right lower extremity. The patient was subsequently hospitalized with increasing right hip pain and leg edema. A colorless transparent lymph fluid leaked from his leg, and leg lymphedema was thus diagnosed. The patient also had a 20-year history of myelodysplastic syndrome. Therefore, the extensive or total resection of the bursa was considered to be too invasive, so a partial bursal excision was performed via an anterior approach. Following the partial bursal excision, total hip arthroplasty (THA) was performed using the Hardinge approach. The leg lymphedema disappeared following the surgery, and the iliopectineal bursa was no longer enlarged. MTX and tacrolimus were postoperatively administered to strictly control the RA. The RA was subsequently well controlled, without any increases in the levels of inflammatory markers, such as C-reactive protein and matrix metalloproteinase-3. This case demonstrated that iliopectineal bursitis was resolved following THA, without complete excision of the intrapelvic bursa, and that strict RA control led to a good clinical course without recurrent inflammation of the bursa. Similar procedures may be beneficial in other patients contraindicated for resection of the entire bursa.

    Patients who participated in a Phase 2 trial of HP802-247 for venous leg ulcers were invited to participate in this 24-week follow-up study to assess the durability of healing, document additional ulcer closures, and evaluate posttreatment safety. Consent was given by 90% (206/228), with 80% (183/228) completing all visits. Blinding was retained from the previous trial in which subjects had been randomized to vehicle or one of four cell therapy regimens. Visits were every 8 weeks. Among the 183 subjects, 43% (21/49) previously treated with cells and entering follow-up with an open wound achieved closure, compared with 35% (7/20) previously treated with vehicle, while 10% (11/106) and 17% (3/18), respectively, experienced reopening of a previously closed wound. Subjects previously treated with cells closed more open wounds than those previously treated with vehicle (OR 1.39, 95% CI 0.47-4.10; p = 0.739), and less subjects with a previously closed wound reopened (OR 0.65, CI 0.16-2.60; p = 0.821); however, these findings were not statistically significant. At the final visit, the difference in proportion of subjects with wounds closed continued to favor the best dose from the prior trial (83% closed vs. 58%, delta 25%). Follow-up beyond 12 weeks is necessary to evaluate the full benefit of this therapy, as treatment with cells may provide stimulus toward healing that persists for up to several weeks following the last application. The results show that the greater proportional benefit achieved by HP802-247 relative to standard care after 12 weeks of treatment persists over a meaningful timeframe.

    Previous structure-activity and pharmacologic studies with duodenal ulcerogens cysteamine and propionitrile implicating catecholamines in the pathogenesis of duodenal ulceration have now been followed up by dose- and time-response biochemical investigations to assess the importance of monoamines in the development of duodenal ulcers. The concentrations of norepinephrine (noradrenaline), dopamine, serotonin and their metabolites were measured in total brain, brain regions, stomach, duodenum, pancreas and adrenals in the rat. Turnover of catecholamines was determined in rats pretreated with the inhibitor of tyrosine hydroxylase alpha-methyl-p-tyrosine. The duodenal ulcerogens caused a dose- and time-dependent depletion of norepinephrine in virtually all the tissues examined. The effect was maximal 4 or 7 hr after cysteamine or propionitrile, and norepinephrine levels returned to normal in 24 hr. Dopamine changes were selective and often biphasic, e.g., elevation in adrenals, biphasic in brain cortex, hippocampus and midbrain, but uniformly decreasing in glandular stomach and duodenum. In the median eminence dopamine levels decreased by 181 and 324% at 15 and 30 min, respectively, after cysteamine, but neither dopamine nor 3,4-dihydroxyphenylacetic acid was modified in the periventricular nucleus. Serotonin levels were relatively stable, revealing slight elevations or no changes in most of the tissues. The turnover of norepinephrine was accelerated by both chemicals in virtually all brain regions, but dopamine turnover was affected only in a few areas, e.g., in the corpus striatum and medulla oblongata cysteamine decreased dopamine turnover, whereas propionitrile first (at 1 hr) accelerated then (at 8 hr) significantly suppressed it.(ABSTRACT TRUNCATED AT 250 WORDS)

    One-legged cycling has served as a valuable research tool and as a training and rehabilitation modality. Biomechanics of one-legged cycling are unnatural because the individual must actively lift the leg during flexion, which can be difficult to coordinate and cause premature fatigue. We compared ankle, knee, and hip biomechanics between two-legged, one-legged, and counterweighted (11.64 kg) one-legged cycling. Ten cyclists performed two-legged (240 W), one-legged (120 W), and counterweighted one-legged (120 W) cycling (80 rpm). Pedal forces and limb kinematics were recorded to determine work during extension and flexion. During counterweighted one-legged cycling relative ankle dorsiflexion, knee flexion, and hip flexion work were less than one-legged but greater than two-legged cycling (all P < .05). Relative ankle plantar flexion and hip extension work for counterweighted one-legged cycling were greater than one-legged but less than two-legged cycling (all P < .05). Relative knee extension work did not differ across conditions. Counterweighted one-legged cycling reduced but did not eliminate differences in joint flexion and extension actions between one- and two-legged cycling. Even with these differences, counterweighted one-legged cycling seemed to have advantages over one-legged cycling. These results, along with previous work highlighting physiological characteristics and training adaptations to counterweighted one-legged cycling, demonstrate that this exercise is a viable alternative to one-legged cycling.

    We studied a patient with edema secondary to protein losing enteropathy, and recurrent bouts of bloating and abdominal pain secondary to intestinal subocclusion episodes. After the clinical study, the patient was diagnosed of cryptogenic multifocal ulcerous stenosing enteritis (CMUSE), that is a rare disease, probably caused by mutations in the gene PLA2G4A, and characterized by multiple short stenosis of the small bowel with superficial ulcers, which do not exceed the submucosa layer. Inflammatory bowel disease (Chron's disease), intestinal tuberculosis and intestinal ulcers secondary to non-steroidal anti-inflammatory drugs are the main differential diagnosis. To sum up, physicians should included CMUSE in the differential diagnosis of recurrent abdominal pain, iron deficiency anaemia, occult intestinal bleeding, edema and protein losing enteropathy.

    Myiasis is usually caused by flies of the Calliphoridae family, and Cochliomyia hominivorax is the etiological agent most frequently found in myiasis. The first case of myiasis in a diabetic foot of a 54-year-old male patient in Argentina is reported. The patient attended the hospital of the capital city of Tucumán Province for a consultation concerning an ulcer in his right foot, where the larval specimens were found. The identification of the immature larvae was based on their morphological characters, such as the cylindrical, segmented, white yellow-coloured body and tracheas with strong pigmentation. The larvae were removed, and the patient was treated with antibiotics. The larvae were reared until the adults were obtained. The adults were identified by the setose basal vein in the upper surface of the wing, denuded lower surface of the wing, short and reduced palps, and parafrontalia with black hairs outside the front row of setae. The main factor that favoured the development of myiasis is due to diabetes, which caused a loss of sensibility in the limb that resulted in late consultation. Moreover, the poor personal hygiene attracted the flies, and the foul-smelling discharge from the wound favoured the female's oviposition. There is a need to implement a program for prevention of myiasis, in which the population is made aware not only of the importance of good personal hygiene and home sanitation but also of the degree of implication of flies in the occurrence and development of this disease.

    Trophic leg ulcer is a major health problem affecting approximately 1-2% of the population, the incidence being higher in the elderly (70-80 years). It is a multifactorial condition, but the most common cause is chronic venous insufficiency. This can be attributed to reflux in the saphenous system and calf perforator vein incompetence. These were first described by Linton, the first intervention designed to correct perforator vein incompetence bearing his name. Today Linton's operation has been abandoned due to the large unaesthetic incision and great postoperative pain. Also, ulcer healing time is long (2 months) and recurrence rate is high. Currently a series of minimally invasive procedures are used to close these perforator veins, such as ultrasound-guided sclerotherapy. The advantages of these techniques are less discomfort to the patients, low rate of complications, short hospital stay.

    2005-06-01

    This review discusses the epidemiology, pathogenesis, diagnosis and current therapeutic options for venous ulcer. Venous ulcer is a severe clinical manifestation of chronic venous insufficiency (CVI). It is responsible for about 70% of chronic ulcers of the lower limbs. The high prevalence of venous ulcer has a significant socioeconomic impact in terms of medical care, days off work and reduced quality of life. Long-term therapeutics are needed to heal venous ulcers and recurrence is quite common, ranging from 54 to 78%. Thrombophlebitis and trauma with long-term immobilization predisposing to deep venous thrombosis are important risk factors for CVI and venous ulcer. The most recent theories about pathogenesis of venous ulcer have associated it with microcirculatory abnormalities and generation of an inflammatory response. Management of venous leg ulcers is based on understanding the pathogenesis. In recent years novel therapeutic approaches for venous ulcers have offered valuable tools for the management of patients with this disorder.

We took samples of plantar ulcers secretion from 107 patients at Marchoux Institute. 92.5% of those ulcers were infected. These samples revealed 145 strains of micro-organisms among those, Staphylococcus aureus (70 strains) and genus Pseudomonas (41 strains) were the most frequent. These bacteria were resistant to several antibiotics currently used at Marchoux Institute (tetracycline, penicillin, cotrimoxazol and erythromicin). Antibiotics, efficient at 80% on tested strains, were expensive for patients. They cannot be recommended for the treatment of local infections. These results outline that the main treatment in plantar ulcers is based upon antiseptic solutions and keeping feet at rest. Antibiotherapy in case of extension of local infection would be based on the results of a previous study of sensitivity.

    Vincent's angina (Plaut-Vincent) is the most prominent disease caused by coinciding infections from fusibacteria and spirochaeta both belonging to obligate anaerobic bacteria. A possible symbiotic infection of both anaerobics may become manifest on the mucous membranes of the oral cavity and the oropharynx beside the tonsillas. The clinical outcome may be different and pose difficulties in the differential diagnosis. We report the case of a 29 year old female patient with necrotizing ulcera of the soft palate suspicious for stomatitis ulceromembranacea. In case necrotizing inflammations of the oral cavity area were to be found infections due to anaerobic bacteria should be considered mostly occurring as mixed infections. The correct identification by cultivation turns out to be difficult in that it requires special conditions. Furthermore, reliable detection of these bacteria necessitates careful collection and transport of patients specimens. In case of Fusospirochaetosis (Fusotreponematose) a specimen should be prepared for microscopic examination beside setting up a special culture. This is because the staining is the most suitable procedure for bacteril identification to support the clinical diagnosis of stomatitis ulceromembranacea.

    Ulcers commonly occur in the oral cavity, their main symptom being pain. There are different ways to classify oral ulcers. The most widely accepted form divides them into acute ulcers--sudden onset and short lasting--and chronic ulcers--insidious onset and long lasting. Commonest acute oral ulcers include traumatic ulcer, recurrent aphthous stomatitis, viral and bacterial infections and necrotizing sialometaplasia. On the other hand, oral lichen planus, oral cancer, benign mucous membrane pemphigoid, pemphigus and drug-induced ulcers belong to the group of chronic oral ulcers. It is very important to make a proper differential diagnosis in order to establish the appropriate treatment for each pathology.

    Leg ulceration can be defined as any chronic ulcer of the lower leg excluding those on the forefoot or toes (Lees & Lambert, 1992). Venous or stasis ulcers account for 80%-85% of all leg ulcers with an overall prevalence of approximately 1% in the United States (Collins & Seraj, 2010; O'Meara, Al-Kurdi, & Ovington, 2008). Venous ulcers are more common in women and the older population (Abbade & Lastoria, 2005; Bergqvist, Lindholm, & Nelzen, 1999). Venous ulcers are often recurrent and chronic and can persist from weeks to even years. Severe complications include cellulitis, osteomyelitis, and malignant changes (Collins & Seraj, 2010). This column discusses the pathophysiology of venous insufficiency and ulcerations, presentation, diagnosis, and current treatment.

    Abomasal ulcers lead to several problems. They cause pain resulting in a decrease in productivity and even the possible loss of the animal. Because they are frequently difficult to diagnose, information on their prevalence is variable. Additionally, therapeutic options are limited. Abomasal ulcers are graded as type 1 through 4, type 1 being a superficial defect and type 2 an ulcer where a large blood vessel has been eroded, leading to substantial blood loss. Types 3 and 4 are perforated abomasal ulcers leading to local and diffuse peritonitis, respectively. Causes of abomasal ulcers are multifactorial, for example, mistakes in feeding that lead to gastrointestinal disturbances or other diseases that induce stress. Ulcers can also result from side effects of nonsteroidal anti-inflammatory drugs. In principal, the pathophysiological cause is the disturbance of the balance between protective and aggressive mechanisms at the abomasal mucosa due to stress. Clinical symptoms vary and are mostly non-specific. Fecal occult blood tests, hematology and blood chemistry as well as ultrasonographic examination and abdominocentesis can help to establish the diagnosis. Ulcers can be treated symptomatically, surgically and medically. To prevent abomasal ulcers, animals should be kept healthy by providing adequate nutrition and housing as well as early and effective medical care. Stressful management practices, including transport and commingling, should be avoided.

    The pus samples from diabetic foot ulcer patients and urine samples from urinary tract infected patients were collected and inoculated in nutrient agar plates. The colonies showing different morphologies were streaked on selective agar plates. The antibacterial assay of selected commercial antibiotics was tested against the foot ulcer and urinary tract isolates. The result revealed that most of the organisms were found to be resistant against the antibiotics. Screening of antibacterial activity of selected plants, methanol extracts of plants were prepared and tested against foot ulcer pathogens. Among the plants used, the methanolic extract Tragia involucrata was very effective against the foot ulcer pathogens and to separate the compounds present in the methanolic extract of T. involucrata, when it was subjected to column chromatography. The fractions obtained were further checked for their antibacterial property and fraction 1 which inhibited the pathogens, were subjected to thin layer chromatography and the structure of the particular phytochemical compound was elucidated by NMR study. The spices were tested for their antibacterial property against the urinary tract pathogens. Among the spices tested; Allium sativum inhibited the growth of the pathogens isolated from urinary tract infection. It can be concluded that the plants extract can be used to discover natural products that may serve as lead for the development of new pharmaceuticals addressing the major therapeutic needs.

    Fusarium species may cause localised skin infections in immunocompetent individuals. At least half of these infections are preceded by skin breakdown. The lesions are characterised by slow progression and good response to therapy. Here we present a 60-year-old non-diabetic man with stasis ulcers showing Fusarium oxysporum growth in culture of both pus swabs and skin biopsy specimens. The patient was confined to wheelchair because of recurrent sacral chordoma of 15 years duration, which was not under treatment for the last 3 years. Leg ulcers were resistant to antifungal therapy, and healed rapidly after improving of stasis with local and systemic measures.

    Release of corticosterone in hungry kittiwake chicks facilitates begging and allows them to restore depleted energy reserves by increasing parental food provisioning. However, in order to avoid detrimental effects of chronic elevation of corticosterone, chicks might suppress adrenocortical activity in response to prolonged food shortages. In this study we examined temporal dynamics of corticosterone release in red-legged kittiwake (Rissa brevirostris) chicks exposed to prolonged restrictions in energy content and/or nutritional quality (low versus high lipid content) of their food. Starting at the age of 15 days, chicks were fed either high- or low-lipid fish at 40%, 65%, and 100% of ad libitum energy intake. Body mass measurements and baseline plasma samples were taken on a weekly basis after beginning of the treatment. After 3 weeks of treatment, chicks were exposed to a standardized acute handling and restraint stress protocol, where in addition to a baseline sample, three plasma samples were taken at intervals up to 50 min. We found that food-restricted chicks had lower body mass, chronically (during 2-3 weeks) elevated baseline and higher acute stress-induced levels of corticosterone compared to chicks fed ad libitum. Low lipid content of food further exacerbated these effects. An increase in baseline levels of corticosterone was observed within a week after energy requirements of food-restricted chicks exceeded their daily energy intake. A tendency for suppression of adrenocortical activity was observed in treatments fed low-lipid diets only at the end of the experiment. We suggest that nest-bound chicks, if food-stressed, might suffer deleterious effects of chronic elevation of corticosterone.

    Exercise that targets ankle joint mobility may lead to improvement in calf muscle pump function and subsequent healing. The objectives of this research were to assess the impact of an exercise intervention in addition to routine evidence-based care on the healing rates, functional ability and health-related quality of life for adults with venous leg ulcers (VLUs). This study included 63 patients with VLUs. Patients were randomised to receive either a 12-week exercise intervention with a telephone coaching component or usual care plus telephone calls at the same timepoints. The primary outcome evaluated the effectiveness of the intervention in relation to wound healing. The secondary outcomes evaluated physical activity, functional ability and health-related quality of life measures between groups at the end of the 12 weeks. A per protocol analysis complemented the effectiveness (intention-to-treat) analysis to highlight the importance of adherence to an exercise intervention. Intention-to-treat analyses for the primary outcome showed 77% of those in the intervention group healed by 12 weeks compared to 53% of those in the usual care group. Although this difference was not statistically significant due to a smaller than expected sample size, a 24% difference in healing rates could be considered clinically significant. The per protocol analysis for wound healing, however, showed that those in the intervention group who adhered to the exercise protocol 75% or more of the time were significantly more likely to heal and showed higher rates for wound healing than the control group (P = 0·01), that is, 95% of those who adhered in the intervention group healed in 12 weeks. The secondary outcomes of physical activity, functional ability and health-related quality of life were not significantly altered by the intervention. Among the secondary outcomes (physical activity, functional ability and health-related quality of life), intention-to-treat analyses did not support the

    Although simple characterization of discomfort as cramps, heaviness, shooting pains, and so forth can be misleading, history and examination are key to accurate diagnosis. Absence of both dorsalis pedis and posterior tibial pulses strongly suggests peripheral arterial disease (PAD), and the presence of either pulse makes PAD less likely. Hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) are a common cause of lower extremity myalgias. Restless legs syndrome causes nocturnal discomfort but must be distinguished from confounding“mimics." Neurologic causes of leg symptoms include lumbar spinal stenosis, radiculopathy, distal symmetric polyneuropathy, and entrapment neuropathy. Many common causes of leg discomfort can be managed conservatively.

    OBJECTIVE: To present a current review about pathogenesis, pathophysiology, diagnosis, and treatment of peptic ulcer disease in children, based on the reviewed publications and the author personal experience. METHODS: We revised the most relevant articles about peptic ulcer in children, published from the last 20 years. RESULTS: The gastroduodenal peptic ulcer is very common in adults, mostly in the developing countries. Although it is less frequent in children, the optical fibroendoscopy has improved the number of diagnosed cases. The peptic ulcer is classified as its etiology in primary and secondary. The secondary peptic ulcer is related to a subjacent disease or use of drugs, while the primary ulcer happens in the absence of underlying systemic diseases The primary duodenal ulcer is the most common presentation, and there are strong evidences of the H. pylori association in the etiology. Clinical presentation changes with age and ulcer type. Secondary ulcers are mostly acute and sometimes dramatic, while the primary ones have a chronic evolution mostly similar to patients with functional recurrent abdominal pain, but the presence of epigastric pain, feeding-related pain, vomiting, bleeding, familiar history for peptic ulcer, nocturnal pain, and male gender are strongly related to peptic ulcer. The acid antisecretory agents have great efficacy on relieving symptoms and solving ulcerate lesion, although the H. pylori eradication itself prevents primary duodenal ulcer recurrence. CONCLUSIONS: The primary peptic ulcer involve many factors in Its etiopathogenesis, being H. pylori the most important of them Although there isn t yet a ideal therapeutic course. The antibiotics play an important role in peptic ulcer and the H. pylori research must be done for na accurate diagnosis and treatment.

    Peptic ulcer disease had a tremendous effect on morbidity and mortality until the last decades of the 20th century, when epidemiological trends started to point to an impressive fall in its incidence. Two important developments are associated with the decrease in rates of peptic ulcer disease: the discovery of effective and potent acid suppressants, and of Helicobacter pylori. With the discovery of H pylori infection, the causes, pathogenesis, and treatment of peptic ulcer disease have been rewritten. We focus on this revolution of understanding and management of peptic ulcer disease over the past 25 years. Despite substantial advances, this disease remains an important clinical problem, largely because of the increasingly widespread use of non-steroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin. We discuss the role of these agents in the causes of ulcer disease and therapeutic and preventive strategies for drug-induced ulcers. The rare but increasingly problematic H pylori-negative NSAID-negative ulcer is also examined.

    Background Pyoderma gangrenosum–like ulcers and cellulitis of the lower extremities associated with recurrent fevers in patients with X-linked (Bruton) agammaglobulinemia have been reported to be caused by Helicobacter bilis (formerly classified as Flexispira rappini and then Helicobacter strain flexispira taxon 8). Consistent themes in these reports are the difficulty in recovering this organism in blood and wound cultures and in maintaining isolates in vitro. We confirmed the presence of this organism in a patient’s culture by using a novel application of gene amplification polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry. Observation An adolescent boy with X-linked agammaglobulinemia presented with indurated plaques and a chronic leg ulcer whose origin was strongly suspected to be an H bilis organism. Histologic analysis demonstrated positive Warthin-Starry staining of curvilinear rods, which grew in culture but failed to grow when sub-cultured. They could not be identified by conventional techniques. A combination of gene amplification by polymerase chain reaction and electrospray ionization time-of-flight mass spectrometry confirmed the identity of this organism. Conclusions This novel technology was useful in the identification of a difficult-to-grow Helicobacter organism, the cause of pyoderma gangrenosum–like leg ulcers in patients with X-linked agammaglobulinemia. Correct identification of this organism as the cause of pyoderma gangrenosum–like ulcers in patients with X-linked agammaglobulinemia is of great importance for the early initiation of appropriate and curative antibiotic therapy.

    The frequency and nature of exertion pains of the leg in athletes were studied in 2,750 cases of overuse injuries treated at the Sports Clinic of the Deaconess Institute of Oulu, Finland, during the years 1972-1977. 465 cases of exertion pain (18%) were located in the shin. The medial tibial syndrome was the most common overuse injury among these athletes, comprising 9.5% of all exertion injuries and 60% of the leg exertion pains. Together with stress fracture of the tibia, the second most common exertion pain of the leg, it accounted for 75% of the total leg pains. There are certain difficulties in differentiating between the medial tibial syndrome and stress fracture of the tibia. They both occur at the same site with similar symptoms. Radiological examination and isotope scanning are needed. The medial tibial syndrome is an overuse injury at the medial tibial border caused by running exercises. The pain is elicited by exertional ischaemia. The pathogenesis is explained by increased pressure in the fascial compartment of the deep flexor muscles due to prolonged exercise. Similar chronic ischaemic pains from exercise are also found in other fascial compartments of the leg, especially in the anterior compartment. The only treatment needed for stress fractures is rest from training. Fascial compartment pains also usually subside. If chronic fascial syndromes prevent training, fasciotomy is recommended as a reliable method to restore the athlete to normal training without pains. PMID:486888

    Connective tissue disorders (CTD), which are often also termed collagen vascular diseases, include a number of related inflammatory conditions. Some of these diseases include rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis (scleroderma), localized scleroderma (morphea variants localized to the skin), Sjogren’s syndrome, dermatomyositis, polymyositis, and mixed connective tissue disease. In addition to the systemic manifestations of these diseases, there are a number of cutaneous features that make these conditions recognizable on physical exam. Lower extremity ulcers and digital ulcers are an infrequent but disabling complication of long-standing connective tissue disease. The exact frequency with which these ulcers occur is not known, and the cause of the ulcerations is often multifactorial. Moreover, a challenging component of CTD ulcerations is that there are still no established guidelines for their diagnosis and treatment. The morbidity associated with these ulcerations and their underlying conditions is very substantial. Indeed, these less common but intractable ulcers represent a major medical and economic problem for patients, physicians and nurses, and even well organized multidisciplinary wound healing centers.

    The discovery that Helicobacter pylori infection is the major cause of peptic ulcer disease revolutionised our views on the etiology and treatment of the disease. This discovery has tempted many experts to conclude that psychological factors and, specifically, stress are unimportant. However, Helicobacter pylori infection alone does not explain fully the incidence and prevalence of peptic ulcer disease. It has been demonstrated that stress can cause peptic ulcer disease even in the absence of Helicobacter pylori infection, supporting a multicausal model of peptic ulcer etiology. Psychological stress among other risk factors can function as a cofactor with Helicobacter pylori infection.

    A case of spontaneous bacterial peritonitis (SBP) developed in an old man whose ascitic fluid was related neither to portal hypertension nor nephrotic syndrome, but with severe hypoalbuminemia emerged after a massive bleeding from a gastric ulcer in a malnutrition state. Ascitic fluid, increasing day by day, yielded Enterobacter cloacae and Bacteroides fragilis. Though autopsy was not carried out because of refusal of his family, neither liver necropsy, nor abdominal CT scan nor repeated abdominal ultrasonography showed findings suggesting existence of liver cirrhosis. In the presence of his ascites, the extent of a chemiluminescence (CL) response of polymorphonuclear cells from volunteers was significantly lower than that of his serum. This report shows that SBP can develop in a patient with ascites unrelated to portal hypertension when ascitic fluid induces little CL response.

    Primary gastrointestinal (GI) lymphoma is a heterogeneous disease with varied clinical presentations. The stomach is the most common GI site and accounts for 70% to 75% of GI lymphomas. We present a patient with gastric diffuse large B cell lymphoma (DLBCL) who presented with significant weight loss, early satiety, and multifocal ulcerated gastric lesions. Esophagoduodenoscopy should be performed in patients presenting with warning symptoms as in our case. Diagnosis is usually made by endoscopic biopsies. Multiple treatment modalities including surgery, radiotherapy, and chemotherapy have been used. Advancements in endoscopic and pathologic technology decrease turnaround time for diagnosis and treatment initiation, thus reducing the need for surgery. Health care providers should maintain a high level of suspicion and consider gastric DLBCL as part of the differential diagnosis, especially in those with warning symptoms such as weight loss and early satiety with abnormal endoscopic findings.

    2015-01-01

    Background: Brain tumors, traumatic head injury, and other intracranial processes including infections, can cause increased intracranial pressure and lead to overstimulation of the vagus nerve. As a result, increased secretion of gastric acid may occur which leads to gastro-duodenal ulcer formation known as Cushing's ulcer. Methods: A review of original records of Dr. Harvey Cushing's patients suffering from gastro-duodenal ulcers was performed followed by a discussion of the available literature. We also reviewed the clinical records of the patients never reported by Cushing to gain his perspective in describing this phenomenon. Dr. Cushing was intrigued to investigate gastro-duodenal ulcers as he lost patients to acute gastrointestinal perforations following successful brain tumor operations. It is indeed ironic that Harvey Cushing developed a gastro-duodenal ulcer in his later years with failing health. Results: Clinically shown by Cushing's Yale Registry, a tumor or lesion can disrupt this circuitry, leading to gastroduodenal ulceration. Cushing said that it was “reasonable to believe that the perforations following posterior fossa cerebellar operations were produced in like fashion by an irritative disturbance either of fiber tracts or vagal centers in the brain stem.” Conclusion: Harvey Cushing's pioneering work depicted in his Yale registry serves as a milestone for continuing research that can further discern this pathway.

    The effect of long and short-term venous hypertension upon lymph fibrinogen concentrations was studied in an attempt to explain the peri-capillary deposition of fibrin reported in patients with post-phlebitic syndromes. The clearance of radioactive fibrinogen/thrombin clots from the subcutaneous tissues of rats and human volunteers was also studied. Both long- and short-term venous hypertension were found to increase fibrinogen transport across the interstitial space by more than 600%. Not only was there evidence of fibrinolytic activity in the lymph but after long-term venous hypertension alpha 2 antiplasmin activity was also detectable. Skin biopsies from the venous hypertensive ankles showed deposition of interstitial fibrin. The clearance of radioactive fibrinogen/thrombin clots from the subcutaneous tissues of the rat was found to be delayed if the rats were given epsilon amino caproic acid but it could not be increased with stanozolol. In human subjects it was found that patients with lipodermatosclerosis had delayed clot clearance and retarded blood fibrinolytic activity when compared with normal volunteers and patients with uncomplicated varicose veins. The principle cause why tall men are more subject to ulcers than short men, Dr Young conceived to be then length of the column of blood in their veins; which by its pressure, renders the legs less able to recover when hurt by any violence.

    The gastric duodenal mucosa normally is protected from the damaging effects of gastric acid and pepsin by ill-defined mechanisms. Ulcers may arise when there is an imbalance between the aggressive and defensive factors that renders the mucosa susceptible to damage. A variety of factors have been identified that may favor the development of peptic ulcers, but no single pathophysiologic defect applies in all ulcer patients. In duodenal ulcers, gastric acid hypersecretion is observed in as many as one third of patients; however, most patients with duodenal ulcers secrete normal amounts of gastric acid. Decreased mucosal bicarbonate secretion may be important in at least some duodenal ulcer patients. Use of NSAIDs may cause either gastric or duodenal ulcers, probably through the inhibition of mucosal prostaglandin synthesis and disruption of mucosal defenses. Finally, a recently identified bacterium, H. pylori, causes a chronic gastritis that is found in the overwhelming majority of patients with duodenal ulcers and non-NSAID-associated gastric ulcers. This bacterium may play a pivotal role in ulcer pathogenesis and, especially, in ulcer recurrences. A number of drugs of proved efficacy are available for the treatment of acute duodenal and gastric ulcers. The H2 receptor antagonists administered once daily remain the mainstay of ulcer therapy because of their efficacy, ease of use, and excellent safety profile. More thorough and long-lasting acid inhibition is afforded by the H+/K(+)-ATPase inhibitor omeprazole. This agent also promotes more rapid ulcer healing, but in most patients, this minor advantage may not justify the higher cost. It is not known whether more rapid healing will translate into lower ulcer complication rates. Until further data are available, this drug may be preferable in patients with large or complicated ulcers. In patients with refractory ulcers, omeprazole is clearly superior to other available agents. Agents that promote mucosal defense

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

    In this report, we describe the case of an adult male who developed an acute compartment syndrome localized to the anterior compartment of the leg following an ankle sprain. Compartment syndrome in association with ankle sprain is unusual, and has been previously described in association with avulsion of the perforating peroneal artery. Because of the potential for severe morbidity, we feel that it is important to make foot and ankle surgeons aware of this unusual injury.

    Neglected tropical diseases (NTDs) have received increasing attention in recent years by the global heath community, as they cumulatively constitute substantial burdens of disease as well as barriers for economic development. A number of common tropical diseases such as malaria, hookworm or schistosomiasis have well-documented economic impacts. However, much less is known about the population-level impacts of diseases that are rare but associated with high disability burden, which represent a great number of tropical diseases. Using an individual-based model of Buruli ulcer (BU), we demonstrate that, through feedbacks between health and economic status, such NTDs can have a significant impact on the economic structure of human populations even at low incidence levels. While average wealth is only marginally affected by BU, the economic conditions of certain subpopulations are impacted sufficiently to create changes in measurable population-level inequality. A reduction of the disability burden caused by BU can thus maximize the economic growth of the poorest subpopulations and reduce significantly the economic inequalities introduced by the disease in endemic regions.

Endoscopic treatment is fundamental for the management of peptic ulcer bleeding. Despite recent advances in endoscopic treatment, mortality from peptic ulcer bleeding has still remained high. This is because the disease often occurs in elderly patients with frequent comorbidities and are taking ulcerogenic medications. Therefore, the management of peptic ulcer bleeding is still a challenge for clinicians.

    Probiotic lactic acid bacteria are being proposed to cure peptic ulcers by reducing colonization of Helicobacter pylori within the stomach mucosa and by eradicating already established infection. In lieu of that, in vitro inhibitory activity of pediocin-producing probiotic Pediococcus acidilactici BA28 was evaluated against H. pylori by growth inhibition assays. Further, chronic gastritis was first induced in two groups of C57BL/6 mice by orogastric inoculation with H. pylori with polyethylene catheter, and probiotic P. acidilactici BA28 was orally administered to study the eradication and cure of peptic ulcer disease. H. pylori and P. acidilactici BA28 were detected in gastric biopsy and fecal samples of mice, respectively. A probiotic treatment with P. acidilactici BA28, which is able to eliminate H. pylori infection and could reverse peptic ulcer disease, is being suggested as a co-adjustment with conventional antibiotic treatment. The study provided an evidence of controlling peptic ulcer disease, by diet mod

Pressure ulcer prevention: an evidence based analysis The cost-effectiveness of prevention strategies for pressure ulcers in long-term care homes in Ontario: projections of the Ontario Pressure Ulcer Model (field evaluation) Management of chronic pressure ulcers: an evidence-based analysis (anticipated pubicstion date - mid-2009) Purpose A pressure ulcer, also known as a pressure sore, decubitus ulcer, or bedsore, is defined as a localized injury to the skin/and or underlying tissue occurring most often over a bony prominence and caused by pressure, shear, or friction, alone or in combination. (1) Those at risk for developing pressure ulcers include the elderly and critically ill as well as persons with neurological impairments and those who suffer conditions associated with immobility. Pressure ulcers are graded or staged with a 4-point classification system denoting severity. Stage I represents the beginnings of a pressure ulcer and stage IV, the severest grade, consists of full thickness tissue loss with exposed bone, tendon, and or muscle. (1) In a 2004 survey of Canadian health care settings, Woodbury and Houghton (2) estimated that the prevalence of pressure ulcers at a stage 1 or greater in Ontario ranged between 13.1% and 53% with nonacute health care settings having the highest prevalence rate (Table 1).

    An observational study of 2 years was promoted by the Italian Association for Cutaneous Ulcers (AIUC) in order to monitor the epidemiology of leg ulcers, the trend of healing and the more frequent therapeutic approaches in lower limb ulcers. Fifty-nine sites in 14 different Italian regions involved in the study, with 1333 enrolled patients (1163 patients fully evaluated and followed up for 9 months). A prevalence of females (62%) was observed with a mean age of 70 years and a high rate of hypertension (62%), diabetes (38%) and obesity (29%). Venous ulcer was most frequent (55%), followed by mixed (25%) and diabetic (8·3%) ulcers. Basically, all patients received a local therapy (LT) (compression and advanced local therapies), while 63% of patients have an associated systemic pharmaceutical treatment. Ulcer healing rates progressively increased throughout the study and despite the type of observational study does not allow conclusions on the treatment, it was observed that the patients receiving additional systemic drugs were associated with a more rapid acceleration of healing rates of ulcers compared to LT alone (3 months: 39·7% versus 29·2%; 6 months: 62·0% versus 47·0%; 9 months: 74·7% versus 63·8%). In particular, the Studio Ulcere Vascolari (SUV) study showed that a combination treatment with sulodexide and compression therapy allows for a greater increase in the healing rates in venous ulcers.

  8. Does social support impact on venous ulcer healing or recurrence?

    PubMed

    Brown, Annemarie

    2008-03-01

    Much of the leg ulcer literature focuses on clinical assessment and management of chronic venous leg ulceration in order to achieve healing. Chronic venous leg ulceration, however, should be classed as a chronic or long-term condition, defined as a condition,'that is currently not curable and therefore can only be managed', although it is not generally acknowledged as such. There is an extensive body of literature which focuses on the psychosocial issues that impact negatively on the quality of life of patients with long-term conditions, such as diabetes or arthritis. These include the emotional impact of pain, social support, coping mechanisms and response to stress and treatment adherence. Health care professionals are becoming increasingly aware of the impact psychosocial issues may have on wound healing in general, but particularly, in chronic venous leg ulceration and prevention of recurrence. This article reviews the current literature on the role of social support and its impact on venous ulcer healing/recurrence and concludes that health professionals caring for patients with chronic venous ulceration need to consider alternative outcome intervention measures for patients for whom healing may not be a realistic option.

    Ulcerative colitis (UC) is a chronic inflammatory bowel disease affecting the rectum which progressively extents. Its etiology remains unknown and the number of treatments available is limited. Studies of UC patients have identified an unbalanced endoplasmic reticulum (ER) stress in the non-inflamed colonic mucosa. Animal models with impaired ER stress are sensitive to intestinal inflammation, suggesting that an unbalanced ER stress could cause inflammation. However, there are no ER stress-regulating strategies proposed in the management of UC partly because of the lack of relevant preclinical model mimicking the disease. Here we generated the IL10/Nox1dKO mouse model which combines immune dysfunction (IL-10 deficiency) and abnormal epithelium (NADPH oxidase 1 (Nox1) deficiency) and spontaneously develops a UC-like phenotype with similar complications (colorectal cancer) than UC. Our data identified an unanticipated combined role of IL10 and Nox1 in the fine-tuning of ER stress responses in goblet cells. As in humans, the ER stress was unbalanced in mice with decreased eIF2α phosphorylation preceding inflammation. In IL10/Nox1dKO mice, salubrinal preserved eIF2α phosphorylation through inhibition of the regulatory subunit of the protein phosphatase 1 PP1R15A/GADD34 and prevented colitis. Thus, this new experimental model highlighted the central role of epithelial ER stress abnormalities in the development of colitis and defined the defective eIF2α pathway as a key pathophysiological target for UC. Therefore, specific regulators able to restore the defective eIF2α pathway could lead to the molecular remission needed to treat UC. PMID:25014110

    Treatment of peptic ulcer disease has undergone a radical change due to the discovery of its main cause, the Helicobacter pylori infection. The management of the chronic infection is now the primary aim. Treatment of peptic ulcer essentially consists of eradicating H. pylori. A current problem is the resistance developed by H. pylori to the antibiotics used in eradication regimen. Ulcers that are induced by nonsteroidal antirheumatic (NSAR) agents and acetylsalicylic acid are gaining in importance. Optimized inhibition of acid secretion with proton pump inhibitors has made it possible to both prevent and cure ulcers in the stomach and duodenum caused by NSAR agents.

  13. Refractory duodenal ulcer.

    A refractory duodenal ulcer was arbitrarily defined as one that had failed to heal completely after treatment with cimetidine 1 g daily for three months. Of 66 patients with refractory duodenal ulcer, healing eventually occurred in 37 patients, after treatment for an average of 7.4 months. But 28 patients did not heal despite treatment for an average of 9.4 months; and one patient defaulted. In 41 patients the daily dose of cimetidine was increased to 2 g: the ulcers in 31 patients healed. In eight patients the daily dose was increased to 3 g and healing occurred in four patients. Eighteen patients required admission on 22 occasions because of severe symptoms despite treatment. Nine patients underwent surgery but in five the results were poor. Differences in clinical and endoscopic features between refractory and non-refractory ulcer patients were small. Acid and pepsin secretion were similar and gastrin concentrations normal. Blood levels of the drug and suppression of acid secretion were both satisfactory. Identification of refractory ulcer patients at the start of treatment was therefore not possible. Refractoriness could occur at any time during the course of the disease, previous treatment with cimetidine often having resulted in rapid healing, but subsequent relapses were also usually refractory. The cause of refractoriness remains unknown and the rather poor results of surgery in this series suggests that optimal management of these patients remains to be determined. Refractoriness probably indicates a changed natural history of the disease and in some patients a more poor prognosis. PMID:6428982

    1985-05-01

    We report a prospective study of the causes and treatment of 26 long-standing neuropathic ulcers of the foot in 21 patients. The most important causal factor, well illustrated by pressure studies, was the presence of a dynamic or static deformity leading to local areas of peak pressure on insensitive skin. All but one of the 26 ulcers had healed after an average of 10 weeks of treatment in a light, skin-tight plaster cast, with the prohibition of weight-bearing. Recurrent ulceration was prevented in all but one foot by early operation to correct the causative deformity; this was performed after the ulcer had healed and before allowing weight-bearing on the limb. Pressure studies after operation confirmed that pressure points had been relieved.

  15. Effectiveness of olive oil for the prevention of pressure ulcers caused in immobilized patients within the scope of primary health care: study protocol for a randomized controlled trial

    PubMed Central

    2013-01-01

    Background Pressure ulcers are considered an important issue, mainly affecting immobilized older patients. These pressure ulcers increase the care burden for the professional health service staff as well as pharmaceutical expenditure. There are a number of studies on the effectiveness of different products used for the prevention of pressure ulcers; however, most of these studies were carried out at a hospital level, basically using hyperoxygenated fatty acids (HOFA). There are no studies focused specifically on the use of olive-oil-based products and therefore this research is intended to find the most cost-effective treatment and achieve an alternative treatment. Methods/design The main objective is to assess the effectiveness of olive oil, comparing it with HOFA, to treat immobilized patients at home who are at risk of pressure ulcers. As a secondary objective, the cost-effectiveness balance of this new application with regard to the HOFA will be assessed. The study is designed as a noninferiority, triple-blinded, parallel, multi-center, randomized clinical trial. The scope of the study is the population attending primary health centers in Andalucía (Spain) in the regional areas of Malaga, Granada, Seville, and Cadiz. Immobilized patients at risk of pressure ulcers will be targeted. The target group will be treated by application of an olive-oil-based formula whereas the control group will be treated by application of HOFA to the control group. The follow-up period will be 16 weeks. The main variable will be the presence of pressure ulcers in the patient. Secondary variables include sociodemographic and clinical information, caregiver information, and whether technical support exists. Statistical analysis will include the Kolmogorov-Smirnov test, symmetry and kurtosis analysis, bivariate analysis using the Student’s t and chi-squared tests as well as the Wilcoxon and the Man-Whitney U tests, ANOVA and multivariate logistic regression analysis.

On physical examination, hypertension was noted without any cushingoid appearance. Laboratory testing revealed normochromic-normocytic anaemia with positive results of occult blood in the stool, hyperglycaemia and hypokalemia. Upper endoscopy revealed active gastric ulcer with Helicobacter pylori infection, likely causing gastrointestinal bleeding. Endocrine examinations showed that both serum adrenocorticotropic hormone and cortisol were elevated with loss of diurnal variation. A diagnosis of Cushing's disease secondary to pituitary adenoma was made as results of brain MRI and blood sampling from inferior petrosal sinus. In a patient with peptic ulcer disease, physician should be alert to the possible endocrine background.

  18. Drug-induced restless legs syndrome.

    PubMed

    2010-08-01

    Restless legs syndrome can be very troublesome but it has no serious physical complications. The underlying causes are unknown, but it can be triggered or aggravated by a drug. In early 2010, about 60 cases of drug-induced restless legs syndrome had been published in detail. The drugs implicated were mainly psychotropics, especially antidepressants and neuroleptics. Some drugs used to treat restless legs syndrome, especially dopaminergic drugs, can in fact aggravate symptoms. Drug-induced restless legs syndrome generally resolves when the dose is reduced or the drug is withdrawn. Dysfunction of the dopaminergic system has been implicated in some cases. In practice, when a patient presents with restless legs syndrome, the role of a drug, especially a psychotropic, should be considered. Drug withdrawal or a dose reduction may be beneficial.

    Pressure ulcers are painful and cause discomfort, have a negative effect on quality of life, and are costly to treat. The incidence and severity of preventable pressure ulcers is an important indicator of quality of care; it is essential that healthcare providers monitor prevalence and incidence rates to ensure that care strategies implemented are effective. Frail older people are at increased risk of developing pressure ulcers. This article discusses the complexities of preventing pressure ulcers in frail older people and emphasises the importance of structured educational programmes that incorporate effective clinical leadership and multidisciplinary teamwork.

In spite of the thorough clinical and laboratory investigation, in addition to constant changes of the therapeutic approach, the diagnosis of S1 radiculopathy could not be confirmed, resulting in a chronic clinical course; the latter was characterized by relapses and remissions not attributed or linked in any way to the treatment (various types of). In fact, it was due to a routine workup in a sleep clinic, where the patient was referred because of a coincident chronic insomnia (Restless Legs Syndrome is a known and important cause of insomnia/chronic insomnia), which resulted in a proper diagnosis and treatment of this case. With the use of Restless Legs Syndrome appropriate treatment (Pramipexole 0.18 mg taken at bedtime, a dopaminergic agent and Level A recommended drug for Restless Legs Syndrome) an excellent response and immediate elimination of symptoms was achieved. Restless Legs Syndrome may present with a variety of symptoms (with the most prominent shortly being reported with the acronym URGE: Urge to move the legs usually associated with unpleasant leg sensations, Rest induces symptoms, Getting active brings relief, Evening and night deteriorate symptoms); given the fact that Restless Legs Syndrome presents with a great variety and heterogeneity of symptoms (mostly pain, dysesthesia and paresthesia), which may occur in several other diseases (the so called "RLS mimics"), proper diagnosis of Restless Legs Syndrome usually fails. Restless Legs Syndrome misinterpreted as S1 radiculopathy, to the best of our knowledge, has not been reported yet in the literature.

    A technique for individual identification of Amazona was developed using plastic leg bands. Bands were made from 5- and 7-mm-wide strips of laminated PVC coiled 2.5 times with an inside diameter 4-5 mm gt the maximum diameter of the parrot's leg. Seventeen parrots were captured in Puerto Rico, marked with individual plastic leg bands, and observed for 204-658 d with only one lost or damaged plastic band. Plastic leg bands did not cause injury to or calluses on parrots' legs. The plastic material used for making leg bands was available in 18 colors in 1994, which would allow unique marking of 306 individuals using one plastic leg band on each leg.

  2. Cushing's ulcer: the eponym and his own.

    PubMed

    Wijdicks, Eelco F M

    2011-06-01

    One of the least remembered eponyms associated with Harvey Cushing is "Cushing's ulcer." The basis of this credit is a paper published in 1932 in which Cushing describes patients who postoperatively and unexpectedly died of perforated peptic ulcers. It is one of the first descriptions of a stress ulcer and a treatise on the brain-stomach connection. Harvey Cushing was puzzled by the pathogenesis of these peptic ulcerations and perforations and advanced several theories. The least plausible included the bile-vomiting theory suggesting that hemorrhagic ulceration could be produced by a combination of bile and acid in a patient recovering from the anesthetic. Other theories were stimulation of a parasympathetic center in the diencephalon or a disturbance of vagal centers in the brainstem. Quite surprisingly to Cushing, the Boston Herald implicitly insinuated that Cushing found the cause of ulcers and this claim upset him greatly. It is ironic that Harvey Cushing, in his later years with failing health, developed an ulcer himself. Cushing noted in his correspondence that he felt the agitation over this newspaper clipping caused his later ulcer. The first description of a neurogenic ulcer remains an important medical observation and is a testament to Cushing's broad accomplishments.

    The shift of center of pressure (CP) of body and CP of each leg was studied during Achilles tendon vibration of one or both legs while subject was standing with symmetrical load on the legs or with the load transferred on one leg. The CP shift of standing subject during unilateral Achilles tendon vibration depended both on the side of the tendon vibration and on the leg load. When standing with a load transferred on one leg the shift of common CP was larger than when the vibration was applied to the loaded leg. The CP shift of one leg was greater if the vibration, and the load was applied to it. Vibration of unloaded leg caused a CP shift in the contralateral loaded leg. In this case, the vibration of left unloaded leg caused no noticeable CP shift of left leg, while the vibration of the unloaded right leg caused CP shift of right foot. In the same conditions of load and vibration the CP displacement of right leg was larger than the CP shift of left foot. It can be assumed that the change in the load on the leg and unilateral vibration of leg muscles change of the internal representation of the vertical body axis, which affects the CP position of one leg during the muscles vibration.

Patients with venous ulceration (278 patients) were compared with 1401 patients in other categories of clinical classification of venous disease (clinical, etiologic, anatomic, and pathophysiological [CEAP]). Demographic, anthropometric, and clinical data were collected. Univariate and multivariate logistic regression analyses were used. According to multivariate analyses, risk factors for venous ulceration were age, male sex, personal history of superficial and deep venous thrombosis, diabetes, high blood pressure, skeletal or joint disease in the legs and emphysema or chronic obstructive pulmonary disease, higher body mass index and physical inactivity, parental history of ankle ulcer as well as reflux in deep and perforator veins, deep obstruction, and combination of reflux and obstruction. It seems reasonable to pay special attention to patients in whom the postulated risk factors for venous ulceration are present.

    Liver penetration is a rare but serious complication of peptic ulcer disease. Usually the diagnosis is made by operation or autopsy. Clinical and laboratory data were no specific. A 64-year-old man was admitted with upper gastrointestinal bleeding. Hepatic penetration was diagnosed as the cause of bleeding. Endoscopy showed a large gastric ulcer with a pseudotumoral mass protruding from the ulcer bed. Definitive diagnosis was established by endoscopic biopsies of the ulcer base. PMID:15188520

    H. pylori infection is the main cause of peptic ulcer in children. Japan pediatric H. pylori research meeting made the guideline for diagnosis and eradication therapy for H. pylori. This guideline showed the methods for diagnose and the eradication therapy for children with H. pylori infection. Many pediatric patients have been free from some abdominal symptoms after eradication therapy for H. pylori. However we need endoscopy for diagnose in spite of children. And recently new non-invasive diagnostic devices are developed and some species acquired tolerance for clarithromycin. Therefore we hope that a new guideline for children will be written soon.

    Medical and surgical disorders in pregnancy can be can be quite challenging for the obstetrician gynaecologist even in resource rich countries. Reaching an accurate diagnosis and admininstering appropriate management can be difficult in the presence of an on-going pregnancy. The importance of involving specialist from other disciplines (multidisciplinary care) cannot be overemphasized. We present an interesting case of perforated duodenal ulcer in a pregnant patient, review the literature ,discuss the differential diagnosis and evaluate the management principles for this rare condition.

    A case of severe chronic venous insufficiency caused by pulsatile varicose veins in a 46-year-old man with tricuspid regurgitation is presented. Active venous leg ulcer complicated with recurrent venous bleeding and inefficacy of conservative management serve as indications for surgical treatment. This case demonstrates the possibility of radical surgical correction of pathological venous reflux by means of saphenofemoral ligation, foam sclerotherapy and subfascial endoscopic perforator surgery.

    The purpose of this project was to compare the effectiveness of hot particles with different energy betas in producing ulcers on skin. The sources were man-made hot particles similar in size and activity to those found in the commercial nuclear power industry. Four different particle types were used. These were thulium (Tm-170) with a 0.97 MeV maximum energy beta, ytterbium (Yb-175) with a maximum beta energy of 0.47 MeV, scandium (Sc-46) with a 0.36 MeV beta, which was used as a surrogate for cobalt-60 (0.31 MeV beta) and uranium (in the carbide form) with an average maximum beta energy of about 2.5 MeV. Since higher energy beta particles penetrate further in skin, they will affect a higher number and different populations of target cells. The experiments were designed as threshold studies such that the dose needed to produce ulcers ten percent of the time (ED 10%) for each particle type could be compared against each other.

  13. Sitting can cause ischaemia in the subcutaneous tissue of the buttocks, which implicates multilayer tissue damage in the development of pressure ulcers.

    A better understanding of how pressure ulcers develop in the buttocks will improve prophylactic measures. Our aim was to investigate signs of reduced perfusion and ischaemia in the subcutaneous fat in the buttocks during sitting. A microelectrode was used to quantify oxygen (pO(2)). Metabolites that indicate aerobic or anaerobic metabolism (glucose, lactate, pyruvate, and glycerol) were quantified using microdialysis. Sixteen healthy people were studied while they sat on a wheel chair cushion, and a hard surface. Sitting pressures were mapped, and the thickness of the subcutaneous fatty layer was measured. The results showed that pO(2) and glucose were significantly reduced during sitting, and for pO(2) the effect is significantly more profound during sitting on a hard surface. After loading, both glucose and pO(2) increased significantly. We conclude that the subcutaneous adipose tissue covering the ischial tuberosities becomes ischaemic during sitting. This finding supports the theory that not only is the skin involved in early development of pressure ulcers, but also the deeper tissues.

    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.

    Being of the most frequent causes of insomnia, which in the end leads to chronic fatigue, inadequate performance of daily activities, and serious disruption of quality of living, restless legs syndrome (RLS) is nowadays not only a serious medical problem but a socio-economical one as well. Prevalence of the disorder in general population is estimated at 5 to 15%. Family history is positive in over 50% of idiopathic RLS patients which points to genetic basis of the disorder. The characteristics of the secondary or acquired form of RLS are symptoms that start later in life as well as a rapid progression of the disease. On the other hand, idiopathic RLS more often starts at a younger age and the prognoses are better. Over twenty disorders and conditions are brought in connection with secondary RLS. Although the cause of primary RLS is still unknown, there is a strong connection between central metabolism of iron as well as dopamine levels and RLS manifestation. A differential diagnosis of RLS includes a wide specter of motor and sensory disorders. Diagnosis is based on clinical features and the history of disease. To correctly diagnose idiopathic RLS one must first eliminate secondary causes of RLS and then also exclude any disorders with clinical features that mimic those of RLS. It has been estimated that some 20 to 25% of patients need pharmacological therapy. Best initial therapy is the application of nonergot dopamine agonists. Anticonvulsants, benzodiazepines and opioides can be given to patients who are refractory to dopaminergic therapy, those suffering from RLS with emphasized painful sensory component and those with RLS connected with insomnia.

    We undertook a prospective cohort study to assess risk factors associated with hallux ulceration, and to determine the incidence of healing or amputation, in consecutive patients with diabetes mellitus who were treated over the observation period extending from September 2004 to March 2005, at the Jabir Abu Eliz Diabetic Centre, Khartoum City, Sudan. There were 122 diabetic patients in the cohort (92 males and 30 females) with an overall mean age of 58 +/- 9 years. Fifty-three percent of patients had complete healing within 8 weeks and 43% healed within 20 weeks. The overall mean time to healing was 16 +/- 8 weeks. In 32 (26.2%) patients, osteomyelitic bone was removed, leaving a healed and boneless hallux. The hallux was amputated in 17 (13.9%) patients; in 2 (1.6%) patients it was followed by forefoot amputation and in 7 (5.7%) patients by below-the-knee amputation. In 90 (73.8%) patients the initial lesion was a blister. In conclusion, hallux ulceration is common in patients with diabetes mellitus and is usually preceded by a blister. Neuropathy, foot deformity, and wearing new shoes are common causative factors; and ischemia, osteomyelitis, any form of wound infection, and the size of the ulcer are main outcome determinants. Complete healing occurred in 103 (85%) of diabetic patients with a hallux ulcer. Vascular intervention is important relative to limb salvage when ischemia is the main cause of the ulcer.

  17. Pradaxa-induced esophageal ulcer.

    Pradaxa (dabigatran) is a direct thrombin inhibitor approved for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. We describe a case of esophageal ulceration associated with Pradaxa administration in a 75-year-old man. The patient reported difficulty swallowing and a burning sensation after taking his first dose of Pradaxa. An esophagogastroduodenoscopy (EGD) revealed linear ulcerations in the mid-esophagus. Pradaxa was held beginning the day before the EGD. The patient reported that his pain and difficulty swallowing resolved on stopping Pradaxa. Pradaxa is formulated with a tartaric acid excipient to reduce variability in absorption. We hypothesise that the capsule lodged in the patient's esophagus and the tartaric acid may have caused local damage resulting in an esophageal ulcer. It is important to educate patients on proper administration of Pradaxa, to decrease the risk of this rare, but potentially serious adverse event.

    as much as 400%, to increase the frequency and duration of hospitalization, and to decrease the quality of life of affected patients. The cost of treating pressure ulcers has been estimated at approximately $9,000 (Cdn) per patient per month in the community setting. Considering the high prevalence of pressure ulcers in the Ontario health care system, the total cost of treating pressure ulcers is substantial. Technology Wounds normally heal in 3 phases (inflammatory phase, a proliferative phase of new tissue and matrix formation, and a remodelling phase). However, pressure ulcers often fail to progress past the inflammatory stage. Current practice for treating pressure ulcers includes treating the underlying causes, debridement to remove necrotic tissues and contaminated tissues, dressings to provide a moist wound environment and to manage exudates, devices and frequent turning of patients to provide pressure relief, topical applications of biologic agents, and nutritional support to correct nutritional deficiencies. A variety of adjunctive physical therapies are also in use. Method Health technology assessment databases and medical databases were searched from 1996 (Medline), 1980 (EMBASE), and 1982 (CINAHL) systematically up to March 2008 to identify randomized controlled trials (RCTs) on the following treatments of pressure ulcers: cleansing, debridement, dressings, biological therapies, pressure-relieving devices, physical therapies, nutritional therapies, and multidisciplinary wound care teams. Full literature search strategies are reported in appendix 1. English-language studies in previous systematic reviews and studies published since the last systematic review were included if they had more than 10 subjects, were randomized, and provided objective outcome measures on the healing of pressure ulcers. In the absence of RCTs, studies of the highest level of evidence available were included. Studies on wounds other than pressure ulcers and on surgical treatment

  20. Increasing trunk flexion transforms human leg function into that of birds despite different leg morphology.

    PubMed

    2017-02-01

    Pronograde trunk orientation in small birds causes prominent intra-limb asymmetries in the leg function. As yet, it is not clear whether these asymmetries induced by the trunk reflect general constraints on the leg function regardless of the specific leg architecture or size of the species. To address this, we instructed 12 human volunteers to walk at a self-selected velocity with four postures: regular erect, or with 30 deg, 50 deg and maximal trunk flexion. In addition, we simulated the axial leg force (along the line connecting hip and centre of pressure) using two simple models: spring and damper in series, and parallel spring and damper. As trunk flexion increases, lower limb joints become more flexed during stance. Similar to birds, the associated posterior shift of the hip relative to the centre of mass leads to a shorter leg at toe-off than at touchdown, and to a flatter angle of attack and a steeper leg angle at toe-off. Furthermore, walking with maximal trunk flexion induces right-skewed vertical and horizontal ground reaction force profiles comparable to those in birds. Interestingly, the spring and damper in series model provides a superior prediction of the axial leg force across trunk-flexed gaits compared with the parallel spring and damper model; in regular erect gait, the damper does not substantially improve the reproduction of the human axial leg force. In conclusion, mimicking the pronograde locomotion of birds by bending the trunk forward in humans causes a leg function similar to that of birds despite the different morphology of the segmented legs.

    2003-05-01

    To plan for a new community leg ulcer service in one Ontario region, venous ulcer population characteristics and current community care practices were obtained from a home care cohort of people with venous ulcers. A secondary analysis was conducted on the venous ulcer cohort using data collected during a Regional Prevalence and Profile Study. Patients were identified based on the clinical syndrome for venous disease criteria described in the Royal College of Nurses clinical practice guidelines and by the presence of an ankle-brachial pressure index 0.8. The Regional Prevalence and Profile Study identified 263 people with leg ulcers for a rate of 2.0 per 1,000 people >25 years of age. One hundred, seven ulcers (41%) were the result of venous disease; of these, 83 (78% of cases) were associated with a single nursing agency and formed the study cohort. Most patients (51, 61%) were female and 65 years old. Thirty-eight (46%) had 4 comorbid conditions, 63 spoke English, 29 lived alone, 38 did not require physical aids or assistance for mobility, and 81 (98%) were able to travel outside of their home. The current ulcer had been present for an average of 15 months (median 6 months), 51 participants had a previous leg ulcer, and 22 had episodes of ulceration for > 5 years. Of the 121 ulcers in the study, 48 (41%) were located at the ankle, and the majority (85%) were > 1 cm2. General practitioners were the main medical care providers for 48 participants, and 52 (62%) had seen a specialist physician for their current ulcer. These findings are similar to large studies conducted in other industrialized countries and confirm that venous ulcers are a chronic problem in a population with complex health needs.

    Pressure ulcer in an otherwise sick patient is a matter of concern for the care givers as well as the medical personnel. A lot has been done to understand the disease process. So much so that USA and European countries have established advisory panels in their respective continents. Since the establishment of these organizations, the understanding of the pressure ulcer has improved significantly. The authors feel that the well documented and well publicized definition of pressure ulcer is somewhat lacking in the correct description of the disease process. Hence, a modified definition has been presented. This disease is here to stay. In the process of managing these ulcers the basic pathology needs to be understood well. Pressure ischemia is the main reason behind the occurrence of ulceration. Different extrinsic and intrinsic factors have been described in detail with review of literature. There are a large number of risk factors causing ulceration. The risk assessment scales have eluded the surgical literature and mostly remained in nursing books and websites. These scales have been reproduced for completion of the basics on decubitus ulcer. The classification of the pressure sores has been given in a comparative form to elucidate that most of the classifications are the same except for minor variations. The management of these ulcers is ever evolving but the age old saying of “prevention is better than cure” suits this condition the most. PMID:23162223

    2000-01-01

    Despite the increasing popularity of intrathecal infusions to treat patients with long-term non-cancer-related pain, this therapy is not without serious side-effects. Five out of 23 patients who had intrathecal infusions of opiates for longer than 24 months developed leg and feet edema. As predisposing factors, cardiovascular disease, deep venous thrombosis, peripheral vascular disease, and venous stasis of the lower extremities were considered. Every patient who developed pedal and leg edema after the implantation of an infusion pump was also found to have leg edema and venous stasis prior to the time when the pump was inserted. This complication was severe enough to limit their physical activity, and to produce lymphedema, ulcerations and hyperpigmentation of the skin. Reduction of the edema occurred when the dose of the opiate was decreased, and in two cases in which the infusion was discontinued, there was almost complete resolution of the syndrome. It appears that the pre-existence of pedal edema and of venous stasis is a relative contraindication to the long-term intrathecal infusion of opiates in patients with chronic non-cancer pain.

    Treatment of refractory ulcerative colitis (UC) is a common clinical challenge. In either acute or chronic refractory UC, the disease may continue to remain active, even though the patient is on appropriate therapy. It is important to reassess and characterize the patient's disease before adding new medications to the current medical regimen. After determining the current extent and severity of the UC—ruling out other causes of bloody diarrhea and determining what complications are present—new treatment approaches can then be started. It is critical to first optimize oral 5-aminosalicylic acid (5-ASA) therapy combined with rectal 5-ASA or corticosteroid suppositories, plus corticosteroid or 5-ASA enemas or foam preparations. Oral or intravenous corticosteroids are appropriate to use if needed, but alternative approaches must be used for long-term maintenance. 6-Mercaptopurine (6-MP) or azathioprine can be very helpful for severe chronic refractory UC. In those patients who do not respond to 5-ASA medications, corticosteroids, and 6-MP or azathioprine, infliximab offers an important approach for induction and maintenance of remission for refractory chronic ulcerative colitis as well as for select cases of refractory acute UC. Cyclosporine use is an alternative medical approach for the refractory acute UC patient. Colectomy with ileal pouch-anal anastomosis remains a valuable option for the refractory chronic or acute UC patient, because it can provide both a “cure” for the disease, as well as eliminate ineffective medications with their associated side effects.

    Corneal Ulcer is a very common disease in agricultural countries and it is responsible for 10% of the blindness causes. One of the main aspects to be observed in these cases is the increasing or decreasing of the affected area. We have been developing an automatic optical system in order to evaluate the affected area (the ulcer) to be implemented in a public hospital (400 patients per week are analyzed). The optical system is implemented in a Slit Lamp and connected to a CCD detector. The image is displayed in a PC monitor by a commercial frame grabber and a dedicated software for determining the area of the ulcer has been developed.

    Objective To determine whether recurrence of leg ulcers may be prevented by surgical correction of superficial venous reflux in addition to compression. Design Randomised controlled trial. Setting Specialist nurse led leg ulcer clinics in three UK vascular centres. Participants 500 patients (500 legs) with open or recently healed leg ulcers and superficial venous reflux. Interventions Compression alone or compression plus saphenous surgery. Main outcome measures Primary outcomes were ulcer healing and ulcer recurrence. The secondary outcome was ulcer free time. Results Ulcer healing rates at three years were 89% for the compression group and 93% for the compression plus surgery group (P=0.73, log rank test). Rates of ulcer recurrence at four years were 56% for the compression group and 31% for the compression plus surgery group (P<0.01). For patients with isolated superficial reflux, recurrence rates at four years were 51% for the compression group and 27% for the compress plus surgery group (P<0.01). For patients who had superficial with segmental deep reflux, recurrence rates at three years were 52% for the compression group and 24% for the compression plus surgery group (P=0.04). For patients with superficial and total deep reflux, recurrence rates at three years were 46% for the compression group and 32% for the compression plus surgery group (P=0.33). Patients in the compression plus surgery group experienced a greater proportion of ulcer free time after three years compared with patients in the compression group (78% v 71%; P=0.007, Mann-Whitney U test). Conclusion Surgical correction of superficial venous reflux in addition to compression bandaging does not improve ulcer healing but reduces the recurrence of ulcers at four years and results in a greater proportion of ulcer free time.

    This paper reviews the history of the transition from the belief that gastrointestinal ulcers are caused primarily by psychological factors to the current state of belief that they are caused primarily by infection and argues that neither is fully accurate. We argue that psychological factors play a significant role as predisposing to vulnerability, modulating of precipitation, and sustaining of gastric ulceration. We review data that challenge the assumption of a simple infectious disease model and adduce recent preclinical data that confirm the predisposing, modulatory, and sustaining roles for psychological factors. We note that others, too, are now challenging the adequacy of the contemporary simple bacterial infection model. We hope to replace the competition between psychology and medicine with cooperation in understanding and treating patients suffering gastric ulceration and ulcer. PMID:23457084

    Pyoderma gangrenosum is an unusual necrotizing noninfective and ulcerative skin disease whose cause is unknown. Ophthalmic involvement in pyoderma gangrenosum is an unusual event. Only a few cases have been reported, from which we can highlight scleral, corneal, and orbital cases. Peripheral ulcerative keratitis is a process which destroys the peripheral cornea. Its cause is still unknown although it is often associated with autoimmune conditions. Pyoderma gangrenosum should be included in the differential diagnosis of peripheral ulcerative keratitis. Early recognition of these manifestations can vary the prognosis by applying the appropriate treatment. We introduce a 70-year-old woman who suffered pyoderma gangrenosum associated with peripheral ulcerative keratitis in her left eye. The patient's skin lesions and peripheral keratitis responded successfully to systemic steroids and cyclosporine A. PMID:26527531

    2005-11-01

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

    of restless legs syndrome brains. This study reveals that there are alterations in the iron management protein profile in restless legs syndrome compared with controls at the site of blood-brain interface suggesting fundamental differences in brain iron acquisition in individuals with restless legs syndrome. Furthermore, the decrease in transferrin receptor expression in the microvasculature in the presence of relative brain iron deficiency reported in restless legs syndrome brains may underlie the problems associated with brain iron acquisition in restless legs syndrome. The consistent finding of loss of iron regulatory protein activity in restless legs syndrome brain tissue further implicates this protein as a factor in the underlying cause of the iron deficiency in the restless legs syndrome brain. The data herein provide evidence for regulation of iron uptake and storage within brain microvessels that challenge the existing paradigm that the blood-brain barrier is merely a transport system.

    OBJECTIVE: To review underlying causes of diabetic foot ulceration, provide a practical assessment of patients at risk, and outline an evidence-based approach to therapy for diabetic patients with foot ulcers. QUALITY OF EVIDENCE: A MEDLINE search was conducted for the period from 1979 to 1999 for articles relating to diabetic foot ulcers. Most studies found were case series or small controlled trials. MAIN MESSAGE: Foot ulcers in diabetic patients are common and frequently lead to lower limb amputation unless a prompt, rational, multidisciplinary approach to therapy is taken. Factors that affect development and healing of diabetic patients' foot ulcers include the degree of metabolic control, the presence of ischemia or infection, and continuing trauma to feet from excessive plantar pressure or poorly fitting shoes. Appropriate wound care for diabetic patients addresses these issues and provides optimal local ulcer therapy with débridement of necrotic tissue and provision of a moist wound-healing environment. Therapies that have no known therapeutic value, such as foot soaking and topical antiseptics, can actually be harmful and should be avoided. CONCLUSION: Family physicians are often primary medical contacts for patients with diabetes. Patients should be screened regularly for diabetic foot complications, and preventive measures should be initiated for those at risk of ulceration. PMID:11398715

    Nongenital HSV 1 presents outside the mucus membrane. Our patient had unusual presentation that caused diagnostic dilemma. 30-year-old native Nigerian female coming with fiancée to the United States presented to our service one day after arrival through ER with a lesion on her right ankle. She was diagnosed with cellulitis, started on antibiotics, and admitted to hospital. She had fever of 39.1°C. Head and neck exam showed multiple sized lesions over tongue and palate and inner aspect of lower lip. Abdomen and genital exam was normal. Skin exam showed lesions over the face and lesions over the lateral aspect of the right leg. There was ulcerated lesion over the right lateral malleolus with surrounding erythema and edema. Her tests showed elevated ESR of 98; HIV test was negative; CT scan of the ankle showed no abscess or osteomyelitis. TB quantiferon was indeterminate; AFB stain and culture were negative; HSV IgM was elevated at 1 : 16; RPR was negative; ANA was negative; malaria screen was negative, and blood cultures were negative for bacteria, fungus, and virus. Debrided wound had no growth of bacteria or fungus or virus. This case illustrates the unusual presentation of the HSV1 outside the mucus membrane and how it can be confused with other conditions that required extensive tests. Therapeutic trail with antiviral medications resolved lesions over the leg and face.

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

    2015-09-01

    Various medications and behavioral treatments for sleep-related leg cramps have been tried, but the quality of the evidence is low. Quinine seems to be effective, but dangerous. β-Agonists may be one of the more common causes of secondary leg cramps. Statins may not be implicated in leg cramps as much as has been believed. Potassium-sparing diuretics may have a higher incidence of sleep-related leg cramps than potassium-depleting diuretics. Plantar flexion of the feet may elicit most sleep-related leg cramps. More research into behavioral treatments is needed. A standardized sleep-related leg cramp questionnaire would be useful to expand research.

    A very common disease in agricultural countries is the corneal ulcer. Particularly in the public hospitals, several patients come every week presenting this kind of pathology. One of the most important features to diagnose the regression of the disease is the determination of the vanishing of the affected area. An automatic system (optical system and software), attached to a Slit Lamp, has been developed to determine automatically the area of the ulcer and to follow up its regression. The clinical procedure to isolate the ulcer is still done, but the measuring time is fast enough to not cause discomfort to the patient as the traditional evaluation does. The system has been used in the last 6 months in a hospital that has about 80 patients per week presenting corneal ulcer. The patients follow up (which is an indispensable criteria for the cure of the disease) has been improved by the system and has guaranteed the treatment success.

    When British attention was drawn to the issue of leprosy in the Empire, humanitarian organisations rose to take on responsibility for the ‘fight against leprosy’. In an effort to fundraise for a distant cause at a time when hundreds of charities competed for the financial support of British citizens, fundraisers developed propaganda to set leprosy apart from all other humanitarian causes. They drew on leprosy’s relationship with Christianity, its debilitating symptoms, and the supposed vulnerability of leprosy sufferers in order to mobilise Britain’s sense of humanitarian, Christian, and patriotic duty. This article traces the emergence of leprosy as a popular imperial humanitarian cause in modern Britain and analyses the narratives of religion, suffering, and disease that they created and employed in order to fuel their growth and sell leprosy as a British humanitarian cause.

  7. Effective leg stiffness in running.

    2009-10-16

    Leg stiffness is a common parameter used to characterize leg function during bouncing gaits, like running and hopping. In the literature, different methods to approximate leg stiffness based on kinetic and kinematic parameters are described. A challenging point in estimating leg stiffness is the definition of leg compression during contact. In this paper four methods (methods A-D) based on ground reaction forces (GRF) and one method (method E) relying on temporal parameters are described. Leg stiffness calculated by these five methods is compared with running patterns, predicted by the spring mass model. The best and simplest approximation of leg stiffness is method E. It requires only easily accessible parameters (contact time, flight time, resting leg length, body mass and the leg's touch down angle). Method D is of similar quality but additionally requires the time-dependent progression of the GRF. The other three methods show clear differences from the model predictions by over- or underestimating leg stiffness, especially at slow speeds. Leg stiffness is derived from a conceptual model of legged locomotion and does not exist without this model. Therefore, it is important to prove which experimental method is suited best for approximating the stiffness in a specific task. This will help to interpret the predictions of the conceptual model in comparison with experimental data.

    Knee braces generally have been rigid in both the knee bending direction and in the knee straightening direction unless a manually operated release is incorporated in them to allow the knee to bend. Desirably a braced knee joint should effectively duplicate the compound, complex, actions of a normal knee. The key to knee braces is the knee joint housing. The housing herein carries a number of cam action pawls. with teeth adapted to engage the internal teeth of a ratchet ring mounted in the housing. Cam action return springs and the shape of the cam action pawl teeth allow rotation of the ratchet ring in a leg straightening direction while still supporting a load. The leg can then be extended during walking while at the same time being prevented by the cam action pawls from buckling in the knee bending direction.

  9. Etiopathogenetic principles and peptic ulcer disease classification.

    PubMed

    Ulceration corresponds to tissue loss, breaching the muscularis mucosae. When ulcers develop in the acid-peptic environment of the gastroduodenum, they are traditionally called peptic ulcer (PUD). Ulcers never develop spontaneously in a healthy gastroduodenal mucosa. Ulceration is the ultimate consequence of a disequilibrium between aggressive injurious factors and defensive mucosa-protective factors. The dominant aggressors are strong acid and high proteolytic (pepsin) activity in gastric secretions. The dominant defensors are the phospholipid surfactant layer, covering the mucus bicarbonate gel, the mucus bicarbonate layer covering the epithelium, the tight junctional structures between the epithelial cells, restricting proton permeability, and the epithelial trefoil peptides, contributing to healing after injury. Initially, acid-peptic aggression was considered the overwhelming cause of PUD, supported by the pioneering work of Schwartz, launching the dictum 'no acid, no ulcer'. This led to the universal therapy directed against intragastric acidity, also interfering with peptic activity when the pH was >4. The therapeutic sequence went from large doses of antacids to H(2)-receptor antagonists and finally to proton pump inhibitors (PPIs). The longer the intragastric pH was >3, the quicker ulcer healing was seen. Unfortunately, ulcers often recurred after stopping therapy, demanding maintenance therapy to keep the ulcers healed and to prevent the need for surgery (vagotomy, partial gastric resection). Later on, the emphasis gradually shifted to weakening/failing of the defensive factors, raising the vulnerability of the gastroduodenal mucosa to luminal secretions. Leading injurious mechanisms jeopardizing the mucosal integrity are numerous: infections, especially Helicobacter pylori, drug-induced injury, particularly acetylsalicylic acid (ASA) and non-steroidal anti-inflammatory drugs (NSAIDs), physicochemical and caustic injury, vascular disorders, interfering

    The lower extremity vascular ulcers currently represent a major public health problem, particularly because of different situations: the chronic nature of the injury, a poor response to treatment, recurrence rates, high absenteeism, poor training in some cases of the health staff that treats, etc. Lower extremity ulcers mean a serious personal, family, health and social problem, with a significant expenditure of human and material resources. Since the prevalence and incidence of lower extremity vascular ulcers is high worldwide, it is necessary to go into detail about the knowledge of the epidemiology and to favour, in different countries, the creation of interdisciplinary research groups that addresses issues related to risk factors, pathogenesis, treatment, health care costs, quality of life and, above all, specialized training aimed at health professionals.

    2012-09-01

    An 86-year-old man with history of travel to Guatemala presented with a 4-month history of an enlarging ulcerative lesion on his right ear. After several weeks of empiric treatment for otitis externa, histopathology, culture, and PCR analysis of a biopsy specimen confirmed the diagnosis of localized cutaneous leishmaniasis secondary to Leishmania mexicana. Known as "Chiclero's ulcer" in southeast Mexico and Latin America, this unique presentation of cutaneous leishmaniasis is caused mainly by the L. mexicana complex. Infection results in a single ulcerative lesion, most commonly involving the ear pinna, without a tendency for cutaneous metastasis, lymphatic or mucosal involvement. The majority of cases of "Chiclero's ulcer" spontaneously re-epithelialize without treatment within 3-9 months. This patient's lesion completely resolved without therapy after 11 months. "Chiclero's ulcer" should be considered in the differential diagnosis of a patient presenting with a chronic ulcerative lesion and history of travel to an endemic area.

    2012-01-01

    Context: Chronic lower leg pain in athletes can be a frustrating problem for patients and a difficult diagnosis for clinicians. Myriad approaches have been suggested to evaluate these conditions. With the continued evolution of diagnostic studies, evidence-based guidance for a standard approach is unfortunately sparse. Evidence Acquisition: PubMed was searched from January 1980 to May 2011 to identify publications regarding chronic lower leg pain in athletes (excluding conditions related to the foot), including differential diagnosis, clinical presentation, physical examination, history, diagnostic workup, and treatment. Results: Leg pain in athletes can be caused by many conditions, with the most frequent being medial tibial stress syndrome; chronic exertional compartment syndrome, stress fracture, nerve entrapment, and popliteal artery entrapment syndrome are also considerations. Conservative management is the mainstay of care for the majority of causes of chronic lower leg pain; however, surgical intervention may be necessary. Conclusion: Chronic lower extremity pain in athletes includes a wide differential and can pose diagnostic dilemmas for clinicians. PMID:23016078

  16. Peptic ulcer disease today.

    2006-02-01

    Over the past few decades, since the introduction of histamine H(2)-receptor antagonists, proton-pump inhibitors, cyclo-oxygenase-2-selective anti-inflammatory drugs (coxibs), and eradication of Helicobacter pylori infection, the incidence of peptic ulcer disease and ulcer complications has decreased. There has, however, been an increase in ulcer bleeding, especially in elderly patients. At present, there are several management issues that need to be solved: how to manage H. pylori infection when eradication failure rates are high; how best to prevent ulcers developing and recurring in nonsteroidal anti-inflammatory drug (NSAID) and aspirin users; and how to treat non-NSAID, non-H. pylori-associated peptic ulcers. Looking for H. pylori infection, the overt or surreptitious use of NSAIDs and/or aspirin, and the possibility of an acid hypersecretory state are important diagnostic considerations that determine the therapeutic approach. Combined treatment with antisecretory therapy and antibiotics for 1-2 weeks is the first-line choice for H. pylori eradication therapy. For patients at risk of developing an ulcer or ulcer complications, it is important to choose carefully which anti-inflammatory drugs, nonselective NSAIDs or coxibs to use, based on a risk assessment of the patient, especially if the high-risk patient also requires aspirin. Testing for and eradicating H. pylori infection in patients is recommended before starting NSAID therapy, and for those currently taking NSAIDs, when there is a history of ulcers or ulcer complications. Understanding the pathophysiology and best treatment strategies for non-NSAID, non-H. pylori-associated peptic ulcers presents a challenge.

  17. Treatment and prognosis in peptic ulcer bleeding.

    Peptic ulcer bleeding is a frequent cause of admission. Despite several advances in treatment the 30-day mortality seems unchanged at a level around 11%. Use of risk scoring systems is shown to be advantageous in the primary assessment of patients presenting with symptoms of peptic ulcer bleeding. Studies performed outside Denmark have demonstrated that use of risk scoring systems facilitates identification of low-risk patients suitable for outpatient management. Nevertheless, these systems have not been implemented for routine use in Denmark. This is mainly explained by concerns about the external validity due to considerable inter-country variation in patients' characteristics. In recent years, transcatheter arterial embolization (TAE) has become increasingly used for achievement of haemostasis in patients with peptic ulcer bleeding not responding to endoscopic therapy. As rebleeding is associated with poor outcome TAE could, in theory, also be beneficial as a supplementary treatment in patients with ulcer bleeding responding to endoscopic therapy. This has not been examined previously. Several studies have concluded that peptic ulcer bleeding is associated with excess long-term mortality. These findings are, however, questioned as the studies were based on life-table analysis, unmatched control groups, or did not perform adequate adjustment for comorbidity. Treatment with blood transfusion is, among patients undergoing cardiac bypass surgery, shown to increase the long-term mortality. Despite frequent use of blood transfusion in treatment of peptic ulcer bleeding a possible adverse effect of on long-term survival has not been examined in these patients.

    1988-01-01

    The relationship between the leg compliance and factors related to the size of leg muscle and to physical fitness was investigated in ten healthy subjects. Vascular compliance of the leg, as determined by a mercury strain gauge, was found to be not significantly correlated with any variables associated with physical fitness per se (e.g., peak O2 uptake, calf strength, age, body weight, or body composition. On the other hand, leg compliance correlated with the calf cross-sectional area (CSA) and the calculated calf volume, with the CSA of calf muscle being the most dominant contributing factor (while fat and bone were poor predicators). It is suggested that leg compliance can be lowered by increasing calf muscle mass, thus providing structural support to limit the expansion of leg veins.

    Peptic ulcer disease (PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer (PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirty-day mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer. PMID:28138363

    2007-01-01

    Differential enlargement of hind (T3) legs represents one of the hallmarks of insect evolution. However, the actual mechanism(s) responsible are yet to be determined. To address this issue, we have now studied the molecular basis of T3 leg enlargement in Oncopeltus fasciatus (milkweed bug) and Acheta domesticus (house cricket). In Oncopeltus, the T3 tibia displays a moderate increase in size, whereas in Acheta, the T3 femur, tibia, and tarsus are all greatly enlarged. Here, we show that the hox gene Ultrabithorax (Ubx) is expressed in the enlarged segments of hind legs. Furthermore, we demonstrate that depletion of Ubx during embryogenesis has a primary effect in T3 legs and causes shortening of leg segments that are enlarged in a wild type. This result shows that Ubx is regulating the differential growth and enlargement of T3 legs in both Oncopeltus and Acheta. The emerging view suggests that Ubx was co-opted for a novel role in regulating leg growth and that the transcriptional modification of its expression may be a universal mechanism for the evolutionary diversification of insect hind legs.

  2. A systematic approach for the diagnosis and treatment of idiopathic peptic ulcers.

    PubMed

    Chung, Chen-Shuan; Chiang, Tsung-Hsien; Lee, Yi-Chia

    2015-09-01

    An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

    2013-01-01

    Corneal ulceration is commonly diagnosed by equine veterinarians. A complete ophthalmic examination as well as fluorescein staining, corneal cytology, and corneal bacterial (aerobic) and fungal culture and sensitivity testing are necessary for all infected corneal ulcers. Appropriate topical antibiotics, topical atropine, and systemic NSAIDs are indicated for all corneal ulcers. If keratomalacia (melting) is observed, anticollagenase/antiprotease therapy, such as autologous serum, is indicated. If fungal infection is suspected, antifungal therapy is a necessity. Subpalpebral lavage systems allow convenient, frequent, and potentially long-term therapy. Referral corneal surgeries provide additional therapeutic options when the globe's integrity is threatened or when improvement has not been detected after appropriate therapy.

    One of the most severe detrimental environmental factors acting during pregnancy is foetal smoke exposure. The aim of this study was to assess the effect of maternal, paternal and parental smoking during pregnancy on relative leg length in 7- to 10-year-old children. The research conducted in the years 2001-2002 included 978 term-born children, 348 boys and 630 girls, at the age of 7-10 years. Information concerning the birth weight of a child was obtained from the health records of the women. Information about the mother's and the father's smoking habits during pregnancy and about the mothers' education level was obtained from a questionnaire. The influence of parental smoking on relative leg length, controlled for age, sex, birth weight and the mother's education, as a proxy measure of socioeconomic status, and controlled for an interaction between sex and birth weight, was assessed by an analysis of covariance, where relative leg length was the dependent variable, smoking and sex were the independent variables, and birth weight as well as the mother's education were the covariates. Three separate analyses were run for the three models of smoking habits during pregnancy: the mother's smoking, the father's smoking and both parents' smoking. Only both parents' smoking showed a significant effect on relative leg length of offspring. It is probable that foetal hypoxia caused by carbon monoxide contained in smoke decelerated the growth of the long bones of foetuses.

  5. Hemodynamic studies of the legs under weightlessness

    NASA Technical Reports Server (NTRS)

    Thornton, W. E.; Hoffler, G. W.

    1974-01-01

    Following exposure to weightlessness, alterations in the return of blood from the legs play a crucial role in orthostatic tolerance and may be an important factor in work tolerance. To investigate some of the hemodynamic mechansism involved, an experiment was performed on the Skylab 3 and Skylab 4 missions to study arterial blood flow, venous compliance, and muscle pumping of blood. Skylab 4 results indicated that the most likely cause of increased blood flow was an increase in cardiac output secondary to increased central venous pressure caused by blood redistribution. Changes in venous compliance are thought to be primarily changes in somatic musculature which is postulated to primarily determine venous compliance of the legs. This was also thought to be demonstrated by the changes in muscle pumping. It is thought that these compliance changes, when taken with the decreased blood volume; provide a basis for the changes seen in orthostatic tolerance, work capacity and lower body negative pressure response.

    Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases. Thus causes and presenting patterns of peptic ulcer have changed. In this review, I describe new diagnostic and therapeutic strategies for peptic ulcer disease and explore future perspectives.

    Patients who undergo intestinal transplantation encounter several complications in the posttransplant period, one of them being ulcer formation in the alimentary tract. During postoperative endoscopic monitoring of 112 pediatric intestinal transplantation patients at our institution, we identified chronic ulcer formation in 11 patients. There were no common or defining demographic or clinical variables that were found in the patients with ulcers. The ulcers could be located within the allograft or in native tissue. Biopsies were obtained from the ulcer edge and the intervening mucosa as well as an evaluation of possible infectious agents. The most common changes in the ulcers were compatible with Epstein-Barr virus-associated posttransplant lymphoproliferative disorder (PTLD; seven cases), acute rejection (six cases), and less commonly, infectious causes (one case). These changes could occur concomitantly and retrospective analysis after therapy showed that the ulcers could have multiple etiologies. Directed biopsies of ulcer edges often displayed morphological changes compatible with acute rejection of the graft, although some biopsies of the intervening mucosa did not show similar changes. Some patients treated based on the changes within the intervening mucosa responded well and led to resolution of the ulcers. Our findings demonstrate that PTLD and acute rejection are the most common causes of chronic ulcer formation and that biopsy samples should be collected simultaneously from both the ulcer edge and intervening mucosa since pathological changes can vary depending on the underlying cause(s). Infectious agents were rarely present but could be seen superimposed with the underlying cause.

    Objectives: The treatment of diabetic ulceration of the lower extremities is a complicated task due to the nature of the ulcer and potential underlying comorbidities. This report describes the case of a 61-year-old male patient with Type 2 Diabetes who presented with an ulcerative leg wound. The objective of this study was to evaluate the outcome of a topical compounded treatment. Methods: The patient applied a compounded medicine containing 2% mupirocin in a topical anhydrous silicone base containing fatty acids from pracaxi oil directly to the ulcer for 63 days, 3 times daily. This regimen was supplemented with exercise and an additional compounded medicine applied to the wound margins in order to increase circulation. Results: By the end of the application period, the patient’s ulcer was fully closed. Conclusion: A topical anhydrous silicone compounding base containing fatty acids from pracaxi oil may be useful in the treatment of patients with diabetic ulcers. PMID:27489690

    Red legs (RL) is a chronic inflammatory condition often misdiagnosed as cellulitis. Antibiotic therapy is not required and does not resolve the symptoms. The main causes of RL are chronic dermatological and venous disease, including chronic oedema. Raising awareness of this condition among health professionals could prevent misdiagnosis and unnecessary costly and potentially harmful antibiotic therapy. The aim of this paper is to highlight the differential diagnoses and management of red legs, and the author also includes an example through a case history.

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

    2012-01-01

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

    The rising prevalence of diabetes estimated at 3.6 million people in the UK represents a major public health and socioeconomic burden to our National Health Service. Diabetes and its associated complications are of a growing concern. Diabetes-related foot complications have been identified as the single most common cause of morbidity among diabetic patients. The complicating factor of underlying peripheral vascular disease renders the majority of diabetic foot ulcers asymptomatic until latter evidence of non-healing ulcers become evident. Therefore, preventative strategies including annual diabetic foot screening and diabetic foot care interventions facilitated through a multidisciplinary team have been implemented to enable early identification of diabetic patients at high risk of diabetic foot complications. The National Diabetes Foot Care Audit reported significant variability and deficiencies of care throughout England and Wales, with emphasis on change in the structure of healthcare provision and commissioning, improvement of patient education and availability of healthcare access, and emphasis on preventative strategies to reduce morbidities and mortality of this debilitating disease. This review article aims to summarise major risk factors contributing to the development of diabetic foot ulcers. It also considers the key evidence-based strategies towards preventing diabetic foot ulcer. We discuss tools used in risk stratification and classifications of foot ulcer.

    Thyroid storm is a rare and life-threatening complication of thyrotoxicosis that requires prompt treatment. Thyroid storm is also known to be associated with precipitating events. The simultaneous treatment of thyroid storm and its precipitant, when they are recognized, in a patient is recommended; otherwise such disorders, including thyroid storm, can exacerbate each other. Here we report the case of a thyroid storm patient (a 55-year-old Japanese male) complicated with a perforated duodenal ulcer. The patient was successfully treated with intensive treatment for thyroid storm and a prompt operation. Although it is believed that peptic ulcer rarely coexists with hyperthyroidism, among patients with thyroid storm, perforation of a peptic ulcer has been reported as one of the causes of fatal outcome. We determined that surgical intervention was required in this patient, reported despite ongoing severe thyrotoxicosis, and reported herein a successful outcome.

    Buruliulcer is an extensive ulceration usually on the extremities. The ulcer can spread to subcutaneous fat, muscle and even bone causing osteomyelitis and death. It is the the third most common mycobacterial disease in humans after tuberculosis and leprosy. The bacterium grows in still standing water and infects children through small ulcerations in their skin. Mycobacterium ulcerans may also be transmitted by the bite of aquatic bugs (Naucordiae), which harbor the bacterium in their salivary glands. The disease affects poor people in rural, tropical areas where deforestation has led to flooding rivers, stagnant bodies of water and marsh. Benin, Cote d'Ivoire and Ghana in West Africa are seriously hit. Skin transplantation is the treatment of choice. Treatment with antibiotics has been disappointing.

    Цель исследования — изучить характер изменений в микроциркуляторном русле в первые 48 ч после поступления больных, сравнить их с клиническими проявлениями кровотечения и выяснить зависимость рецидивов кровотечения от проводимой терапии. Материал и методы. В исследование были включены 108 больных с кровотечениями из язвы желудка и двенадцатиперстной кишки, получавших лечение в ГКБ №71 с 2012 по 2014 г. Среди больных было 80 (74,1%) мужчин и 28 (25,9%) женщин. Возраст больных от 20 до 87 лет (в среднем 54,4±16,8 года). Чаще всего встречались больные моложе 45 лет, их было 33,4%. Для характеристики источника кровотечения использовали классификацию J. Forrest (1974 г.). Прогностическую шкалу оценки желудочно-кишечного кровотечения по Роккал применяли по отношению ко всем больным при поступлении для оценки риска возможных рецидивов. Больные были разделены на две группы: 1-я группа — 53 (49,1%) человека без рецидива язвенного кровотечения, 2-я группа — 55 (50,1%) больных, у которых в ходе проводимого лечения в течение первых 2 сут возник рецидив кровотечения. Результаты. Исследование микроциркуляции свидетельствовало о включении вегетативного компонента в виде централизации кровообращения, замедления кровотока, перераспределения форменных элементов крови, обеспечивающих достаточную оксигенацию крови. К концу первых суток на фоне проводимого лечения отмечены выраженная гемодилюция, уменьшение оксигенации крови, реструктуризация кровотока за счет его ускорения, превышающего 1 мл/с, и нарушение оксигенации тканей, появляются признаки гиперволемии. Эти изменения достоверно отличаются у больных 2-й группы, приводя к «децентрализации» кровообращения, которая может вовлечь в процесс микроциркуляторное русло легочной ткани и вызвать интерстициальный отек, дополнительно способствующий нарушению оксигенации тканей. На этом фоне повышается тромболитическая активность крови и тромбы, образовавшиеся на месте источника кровотечения и еще не организовавшиеся, могут лизироваться. Предполагаем, что рецидив кровотечения, наблюдавшийся у больных 2-й группы, связан с инфузионной терапией в больших объемах, чем это необходимо в такой клинической ситуации. Вывод. При дебюте гастродуоденального язвенного кровотечения следует значительно сократить объем инфузионной терапии. При условии мониторинга для сокращения влияния центральной нервной системы целесообразно включать в лечение седативные препараты.

    Objective To understand the experiences and expectations of nurses in the treatment of women with chronic venous ulcers. Method Phenomenological research was based on Alfred Schütz, whose statements were obtained in January, 2012, through semi-structured interviews with seven nurses. Results The nurse reveals the difficulties presented by the woman in performing self-care, the perceived limitations in the treatment anchored in motivation, and the values and beliefs of women. It showed professional frustration because venous leg ulcer recurrence, lack of inputs, interdisciplinary work and training of nursing staff. There was an expected adherence to the treatment of women, and it emphasized the need for ongoing care, supported self-care and standard practices in treatment. Conclusion That treatment of chronic venous leg ulcers constitutes a challenge that requires collective investment, involving women, professionals, managers and health institutions.

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

    Concern has arisen in recent years that selection for extreme facial morphology in the domestic dog may be leading to an increased frequency of eye disorders. Corneal ulcers are a common and painful eye problem in domestic dogs that can lead to scarring and/or perforation of the cornea, potentially causing blindness. Exaggerated juvenile-like craniofacial conformations and wide eyes have been suspected as risk factors for corneal ulceration. This study aimed to quantify the relationship between corneal ulceration risk and conformational factors including relative eyelid aperture width, brachycephalic (short-muzzled) skull shape, the presence of a nasal fold (wrinkle), and exposed eye-white. A 14 month cross-sectional study of dogs entering a large UK based small animal referral hospital for both corneal ulcers and unrelated disorders was carried out. Dogs were classed as affected if they were diagnosed with a corneal ulcer using fluorescein dye while at the hospital (whether referred for this disorder or not), or if a previous diagnosis of corneal ulcer(s) was documented in the dogs' histories. Of 700 dogs recruited, measured and clinically examined, 31 were affected by corneal ulcers. Most cases were male (71%), small breed dogs (mean± SE weight: 11.4±1.1 kg), with the most commonly diagnosed breed being the Pug. Dogs with nasal folds were nearly five times more likely to be affected by corneal ulcers than those without, and brachycephalic dogs (craniofacial ratio <0.5) were twenty times more likely to be affected than non-brachycephalic dogs. A 10% increase in relative eyelid aperture width more than tripled the ulcer risk. Exposed eye-white was associated with a nearly three times increased risk. The results demonstrate that artificially selecting for these facial characteristics greatly heightens the risk of corneal ulcers, and such selection should thus be discouraged to improve canine welfare.

    We report a case of a patient with acquired immunodeficiency syndrome (AIDS) and ileocecal ulcer. A 31-year-old man was admitted with chief complaints of decreased body weight and abdominal pain. Colonoscopy revealed a round punched-out ulcer on the ileocecal valve. Initially, we suspected entero-Behçet's disease and simple ulcer as the cause of the ileocecal ulcer. However, after histologic examination of tissue biopsies obtained during colonoscopy, we diagnosed the patient as having cytomegalovirus (CMV) enteritis. Based on the patient's white blood cell depletion and CMV enteritis, we performed a human immunodeficiency virus (HIV) antibody test. The test was positive, and the diagnosis of AIDS was established. The number of patients with AIDS has been increasing in Japan; thus, we should consider the possibility of CMV enteritis and AIDS in young adult patients affected by ileocecal ulcer with no notable history.

    Diabetic foot ulcer (DFU) patients have a greater than twofold increase in mortality compared with nonulcerated diabetic patients. We investigated (a) cause of death in DFU patients, (b) age at death, and (c) relationship between cause of death and ulcer type. This was an eleven-year retrospective study on DFU patients who attended King's College Hospital Foot Clinic and subsequently died. A control group of nonulcerated diabetic patients was matched for age and type of diabetes mellitus. The cause of death was identified from death certificates (DC) and postmortem (PM) examinations. There were 243 DFU patient deaths during this period. Ischaemic heart disease (IHD) was the major cause of death in 62.5% on PM compared to 45.7% on DC. Mean age at death from IHD on PM was 5 years lower in DFU patients compared to controls (68.2 ± 8.7 years versus 73.1 ± 8.0 years, P = 0.015). IHD as a cause of death at PM was significantly linked to neuropathic foot ulcers (OR 3.064, 95% CI 1.003–9.366, and P = 0.049). Conclusions. IHD is the major cause of premature mortality in DFU patients with the neuropathic foot ulcer patients being at a greater risk. PMID:27213157

    During the summer of 1933, lesions of a disease were noted among some fingerling brook, rainbow, blackspotted, and lake trout at the Cortland (New York) trout hatchery. Although these lesions bore a marked superficial resemblance to those of furunculosis, they were sufficiently atypical to warrant further investigation. A more detailed examination of the lesions proved them to be of a distinct disease, which for lack of a better name is herein called "ulcer disease," for the lesions closely resemble those described by Calkins (1899) under this name. Because of the marked resemblance to furunculosis, ulcer disease has not been generally recognized by trout culturists, and any ulcer appearing on fish has been ascribed by them to furunculosis without further question.

    2014-01-01

    Ulcerative keratitis is frequently associated with collagen vascular diseases and presents a predilection for peripheral corneal localization, due to the distinct morphologic and immunologic features of the limbal conjunctiva, which provides access for the circulating immune complexes to the peripheral cornea via the capillary network. Deposition of immune complexes in the terminal ends of limbal vessels initiates an immune-mediated vasculitis process, with inflammatory cells and mediators involvement by alteration of the vascular permeability. Peripheral ulcerative keratitis generally correlates with exacerbations of the background autoimmune systemic disease. Associated sceritis, specially the necrotizing form, is usually observed in severe cases, which may evolve in corneal perforation and loss of vision. Although the first-line of treatment in acute phases is represented by systemic administration of corticosteroids, immunosuppressive and cytotoxic agents are necessary for the treatment of peripheral ulcerative keratitis associated with systemic diseases.

    Sea travel mandates changes in the control of the body. The process by which we adapt bodily control to life at sea is known as getting one's sea legs. We conducted the first experimental study of bodily control as maritime novices adapted to motion of a ship at sea. We evaluated postural activity (stance width, stance angle, and the kinematics of body sway) before and during a sea voyage. In addition, we evaluated the role of the visible horizon in the control of body sway. Finally, we related data on postural activity to two subjective experiences that are associated with sea travel; seasickness, and mal de debarquement. Our results revealed rapid changes in postural activity among novices at sea. Before the beginning of the voyage, the temporal dynamics of body sway differed among participants as a function of their (subsequent) severity of seasickness. Body sway measured at sea differed among participants as a function of their (subsequent) experience of mal de debarquement. We discuss implications of these results for general theories of the perception and control of bodily orientation, for the etiology of motion sickness, and for general phenomena of perceptual-motor adaptation and learning.

    This work shows the result obtained in the medical clinic of the `Dr. I. Cantacuzino Hospital' on a lot of 43 diabetic patients using the `LASSIS' devices composed of a He-Ne laser and 4 semiconductor lasers. The 43 patients showed various clinic pictures of a diabetic leg (diabetic arteriopathy and neuropathy) 16 of the lot showed an arteriopathy with claudication and a decrease of pulses oscillometrically measurements, 15 had ulceration and a beginning of gangrene and the other 12 showed a plantary boring ill. There has been achieved an amelioration of the oscillometric index of the claudication while walking the amelioration of local circulation, together with the limitation of the necrosis. For the boring ill, there has been achieved the acceleration of the granulating and epithelization process avoiding surgeries, suppuration and cutaneous plasties. The response to the laser treatment was compared to the response to the classic treatment (vasodilatation surgery unstrapping, antibiotherapy) on a proving lot. We appreciated that the cicatrization and local vasodilatation with athermal laser treatment should be a hope for the treatment of patients suffering of diabetic arteriopathy and neuropathy.

    2002-08-01

    Rheumatic diseases often have gastrointestinal(GI) manifestations, and may present as GI bleeding and perforation due to peptic ulcer associated with high mortality. Major causes of peptic ulcer related to rheumatic diseases are drugs such as nonsteroidal anti-inflammatory drug(NSAID) and corticosteroid, and vasculitis. The analgesic effects of NSAID often mask abdominal pain until they cause GI bleeding and perforation. Therefore, it is important to make early diagnosis of peptic ulcer with upper gastrointestinal endoscope. Fundamental treatment of NSAID induced peptic ulcer is to quit it, however it is difficult because of activity of rheumatic diseases. Also, most NSAID induced peptic ulcers heal by administration of proton pump inhibitor or misoprostol. Corticosteroid pulse therapy or administration of immunosuppressant agents is effective for vasculitis induced peptic ulcer, however it is difficult to make diagnosis of it. Development of NSAID with less side effects such as cyclooxygenase-2 selective inhibitors and establishment of diagnosis and treatment of peptic ulcer related to rheumatic diseases are expected.

    2015-01-01

    Sleep disturbances are important nonmotor symptoms in Parkinson's disease (PD) that are associated with a negative impact on quality of life. Restless legs syndrome (RLS), which is characterized by an urge to move the legs accompanied by abnormal leg sensations, can coexist with PD, although the pathophysiology of these disorders appears to be different. RLS and PD both respond favorably to dopaminergic treatment, and several investigators have reported a significant relationship between RLS and PD. Sensory symptoms, pain, motor restlessness, akathisia, and the wearing-off phenomenon observed in PD should be differentiated from RLS. RLS in PD may be confounded by chronic dopaminergic treatment; thus, more studies are needed to investigate RLS in drug-naïve patients with PD. Recently, leg motor restlessness (LMR), which is characterized by an urge to move the legs that does not fulfill the diagnostic criteria for RLS, has been reported to be observed more frequently in de novo patients with PD than in age-matched healthy controls, suggesting that LMR may be a part of sensorimotor symptoms intrinsic to PD. In this paper, we provide an overview of RLS, LMR, and PD and of the relationships among these disorders. PMID:26504610

  16. Cytoprotection with misoprostol: use in the treatment and prevention of ulcers.

    PubMed

    Ballinger, A

    1994-01-01

    Prostaglandins protect the gastric mucosa by decreasing gastric acid secretion, increasing mucus and bicarbonate production and maintaining mucosal blood flow. Non-steroidal anti-inflammatory drugs (NSAIDs) cause gastroduodenal damage and this is due, at least in part, to inhibition of mucosal prostaglandin production. Misoprostol is a synthetic analogue of prostaglandin E1 which has been used in the healing of ulcers and prevention of peptic ulcers in patients taking NSAIDs. Misoprostol is of equal efficacy to H2 antagonists in the healing of ordinary peptic ulcers (not associated with NSAIDs). Misoprostol is superior to placebo in healing NSAID ulcers during continued NSAID treatment but there have been no comparative trials with other ulcer-healing drugs. Misoprostol, H2 antagonists and sucralfate are of similar efficacy in prevention of NSAID-associated duodenal ulcers but misoprostol is more effective in prevention of gastric ulcers. Misoprostol has not been compared to omeprazole in this situation.

    Buruli Ulcer is a devastating skin disease caused by the pathogen Mycobacterium ulcerans. Emergence and distribution of Buruli ulcer cases is clearly linked to aquatic ecosystems, but the specific route of transmission of M. ulcerans to humans remains unclear. Relying on the most detailed field data in space and time on M. ulcerans and Buruli ulcer available today, we assess the relative contribution of two potential transmission routes -environmental and water bug transmission- to the dynamics of Buruli ulcer in two endemic regions of Cameroon. The temporal dynamics of Buruli ulcer incidence are explained by estimating rates of different routes of transmission in mathematical models. Independently, we also estimate statistical models of the different transmission pathways on the spatial distribution of Buruli ulcer. The results of these two independent approaches are corroborative and suggest that environmental transmission pathways explain the temporal and spatial patterns of Buruli ulcer in our endemic areas better than the water bug transmission.

    Treatment of chronic wounds can present a challenge, with many patients remaining refractory to available advanced therapies. As such, there is a strong need for the development of new products. Unfortunately, despite this demand, few new wound-related drugs have been approved over the past decade. This is in part due to unsuccessful clinical trials and subsequent lack of Food and Drug Administration (FDA) approval. In this article, we discuss the FDA approval process, how it relates to chronic wound trials, common issues that arise, and how best to manage them. Additionally, problems encountered specific to diabetic foot ulcers (DFU) and venous leg ulcers (VLU) are addressed. Careful construction of a clinical trial is necessary in order to achieve the best possible efficacy outcomes and thereby, gain FDA approval. How to design an optimal trial is outlined.

    Buruli ulcer, caused by the pathogen Mycobacterium ulcerans, is a major mycobacteriosis that affects people in scattered foci in the third world. It is amongst the most neglected of diseases in terms of primary healthcare strategies. However, this is changing as the World Health Organization launches a number of major global initiatives. Recent progress includes the unraveling of the genetic structure of the pathogen, examination of the mechanisms of virulence and the role of chemotherapy in disease treatment and prevention of recurrence, together with strategies aimed at reducing the economic burdens placed upon healthcare budgets of poorer nations. This review focuses upon the recent developments and the understanding of the disease, with particular focus on potential chemotherapy.

  20. Pipe crawler with extendable legs

    DOEpatents

    Zollinger, W.T.

    1992-06-16

    A pipe crawler for moving through a pipe in inchworm fashion having front and rear leg assemblies separated by air cylinders to increase and decrease the spacing between assemblies. Each leg of the four legs of an assembly is moved between a wall-engaging, extended position and a retracted position by a separate air cylinder. The air cylinders of the leg assemblies are preferably arranged in pairs of oppositely directed cylinders with no pair lying in the same axial plane as another pair. Therefore, the cylinders can be as long as a leg assembly is wide and the crawler can crawl through sections of pipes where the diameter is twice that of other sections. The crawler carries a valving system, a manifold to distribute air supplied by a single umbilical air hose to the various air cylinders in a sequence controlled electrically by a controller. The crawler also utilizes a rolling mechanism, casters in this case, to reduce friction between the crawler and pipe wall thereby further extending the range of the pipe crawler. 8 figs.

    Background: The purpose of this article is to describe the indications, operative technique, outcomes, and systematic review of the literature on the reconstruction of patients with end-stage pressure ulcers using a fillet flap technique. In this technique, the femur, tibia, and fibula are removed from the thigh and leg, and the soft tissue is used as a pedicled, or free, myocutaneous flap for reconstruction. Long-term outcomes, salient surgical technique of flap elevation, and design are detailed for patients who had a fillet of leg flap for reconstruction of extensive pressure ulcers. Methods: The indications, surgical technique, and postoperative outcomes of 5 patients who had pedicled fillet flaps are reviewed including patient age, sex, underlying comorbidities, duration of paraplegia, operative technique, and complications. A systematic review of the literature was performed searching PubMed, Cochrane Database, and Medline with the following MeSH terms: pressure ulcer, pressure sore, decubitus ulcer, fillet flap, and fillet flap. Inclusion criteria were use of a fillet technique, article data on the number of reconstructions before fillet flap, complications, and English language. Results: Most of our patients were male 75% (n = 3) with an average age of 47.5 years, had been paralyzed for an average of 16 years, and had few medical comorbidities. Two patients (3 flaps) required hip disarticulation, 1 patient had a bilateral fillet flaps, and 3 patients had resection of tibia/fibula. After following patients for an average of 1.4 years (4 mo to 2 yr), complications were limited to 1 patient who had partial-thickness flap loss at the distal skin flap that healed by secondary intention and 1 patient who had ulcer recurrence because of noncompliance. Four articles met inclusion criteria for systematic review and 3 were excluded. Conclusions: The fillet of leg flap remains a useful and reliable method of reconstructing end-stage pressure ulcers.

    The Naval Reactors Prime Contractor Team (NRPCT) recommended the development of a gas cooled reactor directly coupled to a Brayton energy conversion system as the Space Nuclear Power Plant (SNPP) for NASA's Project Prometheus. The section of piping between the reactor outlet and turbine inlet, designated as the hot leg piping, required unique design features to allow the use of a nickel superalloy rather than a refractory metal as the pressure boundary. The NRPCT evaluated a variety of hot leg piping concepts for performance relative to SNPP system parameters, manufacturability, material considerations, and comparison to past high temperature gas reactor (HTGR) practice. Manufacturability challenges and the impact of pressure drop and turbine entrance temperature reduction on cycle efficiency were discriminators between the piping concepts. This paper summarizes the NRPCT hot leg piping evaluation, presents the concept recommended, and summarizes developmental issues for the recommended concept.

    Leg compression devices have been used extensively by patients to combat chronic venous insufficiency and by astronauts to counteract orthostatic intolerance following spaceflight. However, the effects of elastic and inelastic leggings on the calf muscle pump have not been compared. The purpose of this study was to compare in normal subjects the effects of elastic and inelastic compression on leg intramuscular pressure (IMP), an objective index of calf muscle pump function. IMP in soleus and tibialis anterior muscles was measured with transducer-tipped catheters. Surface compression between each legging and the skin was recorded with an air bladder. Subjects were studied under three conditions: (1) control (no legging), (2) elastic legging, and (3) inelastic legging. Pressure data were recorded for each condition during recumbency, sitting, standing, walking, and running. Elastic leggings applied significantly greater surface compression during recumbency (20 +/- 1 mm Hg, mean +/- SE) than inelastic leggings (13 +/- 2 mm Hg). During recumbency, elastic leggings produced significantly higher soleus IMP of 25 +/- 1 mm Hg and tibialis anterior IMP of 28 +/- 1 mm Hg compared to 17 +/- 1 mm Hg and 20 +/- 2 mm Hg, respectively, generated by inelastic leggings and 8 +/- 1 mm Hg and 11 +/- 1 mm Hg, respectively, without leggings. During sitting, walking, and running, however, peak IMPs generated in the muscular compartments by elastic and inelastic leggings were similar. Our results suggest that elastic leg compression applied over a long period in the recumbent posture may impede microcirculation and jeopardize tissue viability.(ABSTRACT TRUNCATED AT 250 WORDS).

    Restless legs syndrome (RLS) is a neurological disorder related to abnormal and unpleasant sensations and movements in the legs. It usually occurs at nighttime and thus has a detrimental impact on the ability to sleep, leading to poor patient quality of life. UCB has been developing rotigotine transdermal patch system (Neupro; SPM-962) as a treatment for RLS. This system is designed to replace levels of dopamine in the body via once-daily application of the patch, in a bid to restore proper motor functioning. The rotigotine patch has been authorized for the treatment of RLS since August 2008.

    2004-01-01

    Four patients with nicorandil induced ulceration are described, and the literature on the subject is reviewed. Nicorandil induced ulcers are very painful and distressing for patients. Clinically they appear as large, deep, persistent ulcers that have punched out edges. They are poorly responsive to topical steroids and usually require alteration of nicorandil treatment. The ulceration tends to occur at high doses of nicorandil and all four cases reported here were on doses of 40 mg per day or greater. In these situations reduction of nicorandil dose may be sufficient to promote ulcer healing and prevent further recurrence. However, nicorandil induced ulcers have been reported at doses as low as 10 mg daily and complete cessation of nicorandil may be required. PMID:15201264

    The recognition of Helicobacter pylori infection as a cause of peptic ulcer disease, medical regimens to eradicate the organism, and the widespread use of proton pump inhibition to suppress gastric acid secretion have revolutionized the management of peptic ulcer disease. As a result, successful medical management of peptic ulcer disease has largely supplanted the need for gastric surgery by general surgeons. Surgery is reserved for complications of the disease, refractory disease, or rare causes of ulcer disease such as gastrinoma and Zollinger-Ellison syndrome. In this report, we describe a case of intractable peptic ulcer disease that progressed to gastric outlet obstruction despite maximal medical therapy. We review the diagnostic studies utilized to evaluate the potential etiologies of peptic ulcer disease and the difficulty in diagnosing gastrinoma and Zollinger-Ellison in the setting of potent medical acid suppression therapy.

    The objective of this study was to identify claw lesions causing clinical lameness in lactating Holstein Frisian (HF) crossbred cows in dairy cattle. Seventy dairy farmers were interviewed at the monthly meetings of Progressive Dairy Farmers Association of Ludhiana, Punjab, India. Ten dairy farms were randomly selected as per probability proportional to size and a total of 450 lactating HF crossbred cows were taken into the study. All the lactating cows were scored for locomotion and rear leg view index. Trimming was done in all the clinically lame animals (animals with locomotion scores 2 and 3) and equal number of animals selected randomly from those with locomotion scores 0 and 1. Various claw lesions were evaluated in both the groups. There was a significant relationship between locomotion score and rear leg view index to identify lameness. Sole ulcers and white line fissures were the lesions responsible for clinical lameness. Other lesions did not cause clinical lameness but increased the asymmetry in lactating HF crossbred cows. Both locomotion score and rear leg view index could be reliably used to identify clinical lameness in lactating cattle. PMID:25133012

    Pressure ulcers are a definite problem in our health care system and are growing in numbers. Unfortunately, it is usually the most weak and vulnerable of our culture that faces these complications, causing the patient and their families discomfort, anguish, and economic hardship due to their expensive treatment. Data collected by the tissue viability department showed high incidence of hospital acquire pressure ulcers in the intensive care unit in March 2013. An action plan was initiated and implemented by the tissue viability team, senior nursing management, pressure ulcer prevention (PUP) team and respiratory therapists (RT's) within the ICU. Our objective was to reduce hospital acquired pressure ulcers in the intensive care unit using the plan, do, check, act quality improvement process. PMID:26734370

    Over the past century, since the introduction of non steroidal anti-inflammatory drugs (NSAID), antacid, histamine H2-receptor antagonists (H2RA), proton pump inhibitors (PPI), and discovery of Helicobacter pylori infection, the paradigm of peptic ulcer disease has changed with marked decrease in morbidity and mortality. However, peptic ulcer disease still occupies a position as a major health problem with increase of aged population and NSAIDs usage. In daily general practice, the management of peptic ulcer disease is directed according to the presence of bleeding or not. For non-bleeding peptic ulcer disease, proper acid suppression and the correction of underlying causes such as Helicobacter pylori infection and NSAID use is the main stay of treatment. Though a complete understanding of pathophysiology and a perfect treatment strategy are still a challenge, this guideline aims to provide practical recommendations based on evidences or consensus of experts through in-depth literature review and expert meeting.

  13. Neuropathic Ulcers Among Children With Neural Tube Defects: A Review of Literature.

    2015-12-01

    A trophic ulcer is a pressure ulcer caused by external trauma to a part of the body that is compromised due to disease, vascular insufficiency, or loss of afferent nerve fibers. Spinal dysraphism (ie, neural tube defects [NTD]) such as meningomyelocele is a risk factor for developing these ulcers in adults and pediatric patients. Information regarding the occurrence of trophic ulcers in pediatric patients with NTD is lacking. A review of the English-language literature on skin/neuropathic ulcers in patients with NTDs, irrespective of study design, published between 1975 and 2014, was undertaken using the PubMed database. Search terms included trophic ulcer, neuropathic ulcer, NTDs, and meningomyelocele. From among the more than 200 papers related to skin care in neonates and pediatric patients, 11 addressed skin ulcers in patients of NTD - 1 in French (a review article), 1 in German (a case report), and 9 in English (7 cohort studies and 2 reviewing surgical techniques). Typically, ulcers in patients with NTD are neuropathic (ie, related to nerve pathology). The most common type is meningomyelocele. Patients with NTD present with a spectrum of functional and sensory deficits that impair mobility; other causative factors that may contribute to the occurrence of ulcers include stress to the tissue, the length of time the stress occurs, muscle spasticity, infection, moisture, and nutritional status of the patient. Awareness of ulcer risk and preventive measures, such as maintaining foot flexibility or careful handling bony prominences such as kyphosis, is important. Once an ulcer occurs, management is challenging and involves collaboration of multiple medical, surgical, nutrition, and other specialists. If an ulcer develops and NTD has not been previously treated surgically or the MRI shows evidence of retethering, surgical treatment is needed. More research is needed to help guide ulcer prevention and treatment strategies in pediatric patients with NTD.

    Infected neuropathic ulcerations are the leading cause of diabetes-related partial foot amputations at the Phoenix Indian Medical Center. Ten hallucal ulcerations in seven American Indian patients with hallux limitus were resolved by local wound care and partial first metatarsophalangeal joint resection. The average length of postsurgical follow-up care was 28.8 months. There have been no recurrences of the plantar hallux ulcerations in any of the patients.

  15. Diagnostic and Treatment Approaches for Refractory Peptic Ulcers

    PubMed Central

    2015-01-01

    Refractory peptic ulcers are defined as ulcers that do not heal completely after 8 to 12 weeks of standard anti-secretory drug treatment. The most common causes of refractory ulcers are persistent Helicobacter pylori infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs). Simultaneous use of two or more H. pylori diagnostic methods are recommended for increased sensitivity. Serologic tests may be useful for patients currently taking proton pump inhibitors (PPIs) or for suspected false negative results, as they are not affected by PPI use. NSAID use should be discontinued when possible. Platelet cyclooxygenase activity tests can confirm surreptitious use of NSAIDs or aspirin. Cigarette smoking can delay ulcer healing. Therefore, patients who smoke should be encouraged to quit. Zollinger-Ellison syndrome (ZES) is a rare but important cause of refractory gastroduodenal ulcers. Fasting plasma gastrin levels should be checked if ZES is suspected. If an ulcer is refractory despite a full course of standard PPI treatment, the dose should be doubled and administration of another type of PPI considered. PMID:26240800

    A peptic ulcer, stomach ulcer, or gastric ulcer, also known as peptic ulcer disease (PUD), is a very common chronic disorder of the stomach which is mainly caused by damage or impairment of the stomach lining. Various factors such as pepsin, gastric acid, H. pylori, NSAIDs, prostaglandins, mucus, bicarbonate, and blood flow to mucosa play an important role in causing peptic ulcers. In this review article, our main focus is on some important gastroretentive drug delivery systems (GRDDS) (floating, bioadhesive, high density, swellable, raft forming, superporous hydrogel, and magnetic systems) which will be helpful in gastroretention of different dosage forms for treatment of peptic ulcer. GRDDS provides a mean for controlled release of compounds that are absorbed by active transport in the upper intestine. It also enables controlled delivery for paracellularly absorbed drugs without a decrease in bioavailability. The above approaches are specific for targeting and leading to a marked improvement in the quality of life for a large number of patients. In the future, it is expected that they will become of growing significance, finally leading to improved efficiencies of various types of pharmacotherapies.

    STUDY OBJECTIVE--Comparison of four layer bandage system with traditional adhesive plaster bandaging in terms of (a) compression achieved and (b) healing of venous ulcers. DESIGN--Part of larger randomised trial of five different dressings. SETTING--Outpatient venous ulcer clinic in university hospital. PATIENTS--(a) Pressure exerted by both bandage systems was measured in the same 20 patients. (b) Healing with the four layer bandage was assessed in 148 legs in 126 consecutive patients (mean age 71 (SE 2); range 30-96) with chronic venous ulcers that had resisted treatment with traditional bandaging for a mean of 27.2 (SE 8) months. INTERVENTIONS--(a) Four layer bandage system or traditional adhesive plaster bandaging for pressure studies; (b) four layer bandaging applied weekly for studies of healing. END POINTS--(a) Comparison of pressures achieved at the ankle for up to one week; (b) complete healing within 12 weeks. MEASUREMENTS AND MAIN RESULTS--(a) Four layer bandage produced higher initial pressures at the ankle of 42.5 (SE 1) mm Hg compared with 29.8 (1.8) for the adhesive plaster (p less than 0.001; 95% confidence interval 18.5 to 6.9). Pressure was maintained for one week with the four layer bandage but fell to 10.4 (3.5) mm Hg at 24 hours with adhesive plaster bandaging. (b) After weekly bandaging with the four layer bandage 110 of 48 venous ulcers had healed completely within 12 (mean 6.3 (0.4)) weeks. CONCLUSION--Sustained compression of over 40 mm Hg achieved with a multilayer bandage results in rapid healing of chronic venous ulcers that have failed to heal in many months of compression at lower pressures with more conventional bandages.

    Objectives The purpose of this study was to compare the joint space width between one-leg and both-legs standing radiographs in order to diagnose a primary osteoarthritis of the knee. Methods Digital radiographs of 100 medial osteoarthritic knees in 50 patients were performed. The patients had undergone one-leg standing anteroposterior (AP) views by standing on the affected leg while a both-legs standing AP view was undertaken while standing on both legs. The severity of the osteoarthritis was evaluated using the joint space width and Kellgren-Lawrence (KL) radiographic classification. The t-test was used for statistical analysis. Results The mean medial joint space width found in the one-leg and in the both-legs standing view were measured at 1.8 mm and 2.4 mm, respectively (p < 0.001, 95% CI 0.5 to 0.7). 33%, 47.4% and 23.1% of the knees diagnosed with a KL grade of I, II and III in the both-legs standing views were changed to KL grade II, III and IV in the one-leg standing views, respectively. No changes for KL IV osteoarthritis diagnoses have been found between both- and one-leg standing views. Conclusions One-leg standing radiographs better represent joint space width than both-legs standing radiographs. 32% of both-legs standing radiographs have changed the KL grading to a more severe grade than that in the one-leg standing radiographs.

    The number of channels used for polysomnographic recording frequently causes difficulties for patients because of the many cables connected. Also, it increases the risk of having troubles during recording process and increases the storage volume. In this study, it is intended to detect periodic leg movement (PLM) in sleep with the use of the channels except leg electromyography (EMG) by analysing polysomnography (PSG) data with digital signal processing (DSP) and machine learning methods. PSG records of 153 patients of different ages and genders with PLM disorder diagnosis were examined retrospectively. A novel software was developed for the analysis of PSG records. The software utilizes the machine learning algorithms, statistical methods, and DSP methods. In order to classify PLM, popular machine learning methods (multilayer perceptron, K-nearest neighbour, and random forests) and logistic regression were used. Comparison of classified results showed that while K-nearest neighbour classification algorithm had higher average classification rate (91.87%) and lower average classification error value (RMSE = 0.2850), multilayer perceptron algorithm had the lowest average classification rate (83.29%) and the highest average classification error value (RMSE = 0.3705). Results showed that PLM can be classified with high accuracy (91.87%) without leg EMG record being present. PMID:27213008

    Refractory PUD is a diagnostic and therapeutic challenge. Optimal management of severe or refractory PUD requires a multidisciplinary team approach, using primary care providers, gastroenterologists, and general surgeons. Medical management has become the cornerstone of therapy. Identification and eradication of H pylori infection combined with acid reduction regimens can heal ulceration and also prevent recurrence. Severe, intractable or recurrent PUD and associated complications mandates a careful and methodical evaluation and management strategy to determine the potential etiologies and necessary treatment (medical or surgical) required.

    The manner in which tri-potassium di-citrato bismuthate (TDB) promotes duodenal ulcer healing is not known. Endoscopic biopsy specimens were taken from the edges of duodenal ulcers from 5 patients before and after treatment with TDB. Using the bismuth contained within this drug as an electron-dense marker, the mode of action of TDB was determined by transmission electron microscopy. TDB was found to promote ulcer healing by adhering to the ulcerative mucosa, thereby providing an effective barrier to the substances which cause and maintain ulceration.

    AIMS—(1) To validate a leg to leg bioimpedance analysis (BIA) device in the measurement of body composition in children by assessment of its agreement with dual energy x ray absorptiometry (DXA) and its repeatability. (2) To establish a reference range of percentage body fat in Hong Kong Chinese children.
METHODS—Sequential BIA and DXA methods were used to determine body composition in 49 children aged 7-18 years; agreement between the two methods was calculated. Repeatability for the BIA method was established from duplicate measurements. Body composition was then determined by BIA in 1139 girls and 1243 boys aged 7-16 years, who were randomly sampled in eight local primary and secondary schools to establish reference ranges.
RESULTS—The 95% limits of agreement between BIA and DXA methods were considered acceptable (−3.3 kg to −0.5 kg fat mass and −3.9 to 0.6% body fat). The percentage body fat increased with increasing age. Compared to the 1993 Hong Kong growth survey, these children had higher body mass index. Mean (SD) percentage body fat at 7years of age was 17.2% (4.4%) and 14.0% (3.4%) respectively for boys and girls, which increased to 19.3% (4.8%) and 27.8% (6.3%) at age 16.
CONCLUSION—Leg to leg BIA is a valid alternative method to DXA for the measurement of body fat. Provisional reference ranges for percentage body fat for Hong Kong Chinese children aged 7-16 years are provided.

    Gastritis and gastric ulcers are an important cause of morbidity and mortality in canine athletes. Although the majority of scientific work on this condition has been performed in ultraendurance racing sled dogs, this condition has been identified in other canine athletes, including sled dogs competing in shorter events and dogs performing off-leash explosive detection duties. The cause of the syndrome is unknown, but current hypotheses propose a link between exercise-induced hyperthermia and loss of gastric mucosal barrier function as an early event in the pathogenesis. Treatment is focused on prevention of clinical disease using acid secretion inhibitors, such as omeprazole, which has excellent efficacy in controlled clinical studies.

    A peptic ulcer in a child looks the same as it does in an adult, and many of the aetiologies of peptic ulcer disease in children are similar to those in adults. However, there are many differences between children and adults, especially in the areas of clinical presentation, the prevalences of different types of ulcer disease, and the prevalence of complications of ulcer disease. Therefore the approach to diagnosis and management in children is often at variance with that in adults. One important example is the approach to suspected Helicobacter pylori (H. pylori) disease in children, in which consensus groups have advised a considerably different approach in children. While the chapter deals with the full range of peptic ulcer disease in children, the focus is on those aspects in which there are differences between adults and children.

    We studied the common kinematic features of the coxa and trochanter in cursorial and raptorial legs, which are the short size of the podomers, predominantly monoaxial joints, and the approximate orthogonality of adjacent joint axes. The chain coxa-trochanter with its short elements and serial orthogonality of joint axes resembles the gimbals which combine versatility and tolerance to external perturbations. The geometry of legs was studied in 23 insect species of 12 orders. Insects with monoaxial joints were selected. The joint between the trochanter and the femur (TFJ) is defined either by two vestigial condyles or by a straight anterior hinge. Direction of the joint axes in the two basal podomers was assessed by 3D measurements or by goniometry in two planes. Length of the coxa is <15% (mostly <8%) of the total length of the cursorial leg, that of the trochanter <10%. Angles between the proximal and distal joint axes in the middle coxa range from 124 to 84 degrees (mean 97+/-14 degrees ), in the trochanter (in all legs studied) from 125 to 72 degrees (mean 90+/-13 degrees ). Vectors of the distal axis in the coxa are concentrated about the normal to the plane defined by the proximal axis and the midpoint between the distal condyles. These vectors in the trochanter lie at various angles to the normal; angles are correlated with the direction of the TFJ relative to the femur. Range of reduction about the TFJ is over 60 degrees in the foreleg of Ranatra linearis, Mantispa lobata and the hind leg in Carabus coriaceus (confirming observations of previous authors), 40-60 degrees in the foreleg of Vespa crabro and in the middle one in Ammophila campestris, 10-30 degrees in other studied specimens. The special role of the trochanter in autotomy and in active propulsion in some insect groups is discussed. The majority of insects possess small trochanters and slightly movable TFJs with the joint axis laying in the femur-tibia plane. We pose the hypothesis that the TFJ

    Since perforated peptic ulcer is uncommon in children proton pump inhibitor prophylaxis is not routinely recommended when children are treated with high dose steroids. We describe a case of perforated ulcer in a six-year-old patient with nephrotic syndrome treated with high dose prednisolone. Initially, ulcer was not suspected due to uncharacteristic symptoms. The child developed peritoneal signs and surgery revealed a perforated peptic ulcer in the stomach. We recommend treatment with proton pump inhibitors if children, who are treated with high dose steroids develop abdominal symptoms, which can be caused by an ulcus.

    The randomised controlled trial (RCT) is often considered the gold standard for judging the benefits of treatments. The application of randomised controlled clinical trials to treatments of venous ulcer healing has lagged behind that of other areas of medicine. To interpret the results of an RCT, readers must understand a variety of aspects of their design, analysis and interpretation. Venous ulcer disease has a high prevalence and has a significant socioeconomic impact in most parts of the world. The management of venous ulcers causes a considerable strain on the health system and is likely to worsen in future. The multi-layer high compression system is described as the current gold standard for treating venous ulcers. A recent meta-analysis of bandaging systems found that multi-layer compression bandages appeared to be superior to single-layer bandages in promoting venous ulcer healing. However, it was noted that many of the studies had small sample sizes and the quality of research in the area was poor. The consolidating standards of reporting trials (CONSORT) statement can help clinicians to discern high-quality studies from ones of poorer quality. This paper discusses how CONSORT can help clinicians and researchers to design and report quality studies to contribute to evidence-based venous ulcer healing.

    Buruli disease (BU) is a progressive necrotic and ulcerative disease of the skin and subcutaneous tissue caused by Mycobacterium ulcerans. BU is considered the third most common mycobacterial disease after tuberculosis and leprosy. Three clinical stages of the cutaneous lesions have been described in BU: pre-ulcerative, ulcerative and healed lesions. In this study we used immunohistochemistry and automated morphometry to determine the percentage of macrophages and of CD4/CD8 lymphocytes and their expression of interferon (IFN)-γ, interleukin (IL)-10, tumour necrosis factor (TNF)-α and transforming growth factor (TGF)-β. Expression of these cytokines was correlated with the inflammatory response evaluated by histopathology. All the studied BU ulcerative cases showed extensive necrosis and chronic inflammation. The most important feature was the presence or absence of granulomas co-existing with a mixed pro-inflammatory/anti-inflammatory cytokine balance. When granulomas were present significantly higher expression of IFN-γ was seen, whereas in ulcerative lesions without granulomas there was increased expression of IL-10 and significantly higher bacillary counts. These features correlated with the chronicity of the lesions; longer-lasting lesions showed granulomas. Thus, granulomas were absent from relatively early ulcerative lesions, which contained more bacilli and little IFN-γ, suggesting that at this stage of the disease strong suppression of the protective cellular immune response facilitates proliferation of bacilli.

    The concept of skin wounds caused primarily as a result of external physical forces has been the focus of many healthcare professionals for decades. Unfortunately, some of the choices made regarding the definition, description, and topical management of pressure ulcers hampers the appreciation of the complexity of issues that generally accompany the occurrence of these wounds. As the healthcare industry increasingly focuses on quality and accountability, industry watchdogs continue to develop metrics to evaluate quality of care while legal professionals demand more accountability for healthcare interventions. The management of pressure ulcers is often scrutinized and many healthcare providers are often unfairly accused of neglect. The occurrence of pressure ulcers, when viewed as a failure of the healthcare system, prevents the comprehensive and constructive attention this topic deserves. Therefore, as wound care providers, we must change the image of pressure ulcers and provide a more balanced portrayal of the influences, treatments, and likely outcomes of these wounds. We must separate fact from fiction and reality from the psychological reaction that pressure ulcers evoke. It is now time to recreate a dialogue for pressure ulcers that is productive, realistic, and likely to result in the advancement of care.

    The aim of this study was to evaluate the effects of LED therapy associated with compression therapy on chronic venous leg ulcers (CVUs). The study included CVU patients (n = 17, eight men) who were eligible for Unna's boot treatment. Ulcers were treated on a weekly basis with either LED therapy (625 nm, 4 J/cm(2)) and an Unna's boot (LED ulcers, n = 14) or a placebo treatment and an Unna's boot (control ulcers, n = 14). The total surface area of the ulcers, the relative ulcer area, and the healing rate were recorded over a period of 30 weeks. Ulcer exudates were collected for determination of local tumor necrosis factor alpha (TNF-α) levels. The total area was not significantly different between the LED and control ulcers (P > 0.05, Mann-Whitney U test) throughout the study. However, the relative area indicated that non-healing treatment resistant ulcers (n = 6) persisted in the control group after 19 weeks (P < 0.05, Mann-Whitney U Test). No differences in median healing rate were observed (hazard ratio 0.89, CI 95%: 0.40-1.98) between LED (15 weeks) and control ulcers (19.5 weeks). No differences in TNF-α levels were detected (P > 0.05, Mann-Whitney U test). The results suggest that LED therapy improved the effectiveness of the Unna's boot since no refractory ulcer was observed in the LED group after 19 weeks. However, LED therapy did not alter the local secretion of TNF-α nor accelerate wound healing.

  12. Prevention and treatment of ulcers induced by nonsteroidal anti-inflammatory drugs: an update.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are most frequently used for the treatment of rheumatic disease due to their anti-inflammatory and analgesic properties. All NSAIDs have the potential to cause damage to the gastrointestinal (GI) tract and have been associated with the induction of peptic ulcers and massive life-threatening bleeding. The therapeutic approaches for the treatment and prevention of NSAID-induced ulcers is critically reviewed using data derived from carefully controlled, world-wide clinical studies with anti-ulcer drugs. Histamine (H2) antagonists, omeprazole, sucralfate and E-prostaglandin (PGE) analogs are effective for the treatment of NSAID-induced gastric and duodenal ulcers, if NSAIDs are discontinued. However, if NSAIDs are continued while GI damage is present, the PGE analogs misoprostol, arbaprostil and enprostil have shown efficacy in healing NSAID-induced ulcers. Furthermore, one limited clinical study demonstrated that omeprazole has efficacy in healing NSAID-associated ulcers. Neither H2 antagonists, sucralfate and sulglycotide (a cytoprotective drug) have shown efficacy in preventing NSAID-induced gastric ulcers. However H2 antagonists have shown efficacy in preventing NSAID-induced duodenal ulcers. In contrast, only misoprostol prevents the development of NSAID-induced gastric and duodenal ulcers. Such pharmacological observations suggest that the pathophysiologic mechanisms for the induction of NSAID-induced gastric ulcer are distinctly different from those of NSAID-induced duodenal ulcers. Mild diarrhea and GI intolerance were the predominant adverse reactions experienced by patients receiving synthetic PGEs, particularly enprostil and arbaprostil. From the published data, we conclude that misoprostol is the only anti-ulcer drug proven to be well tolerated and effective for the treatment and prevention of NSAID-induced gastric and duodenal ulcers in patients receiving chronic NSAIDs therapy.

  13. Pressure ulcer prevention knowledge among Jordanian nurses: a cross- sectional study

    2014-01-01

    Background Pressure ulcer remains a significant problem in the healthcare system. In addition to the suffering it causes patients, it bears a growing financial burden. Although pressure ulcer prevention and care have improved in recent years, pressure ulcer still exists and occurs in both hospital and community settings. In Jordan, there are a handful of studies on pressure ulcer. This study aims to explore levels of knowledge and knowledge sources about pressure ulcer prevention, as well as barriers to implementing pressure ulcer prevention guidelines among Jordanian nurses. Methods Using a cross-sectional study design and a self-administered questionnaire, data was collected from 194 baccalaureate and master’s level staff nurses working in eight Jordanian hospitals. From September to October of 2011, their knowledge levels about pressure ulcer prevention and the sources of this knowledge were assessed, along with the barriers which reduce successful pressure ulcer care and prevention. ANOVA and t-test analysis were used to test the differences in nurses’ knowledge according to participants’ characteristics. Means, standard deviation, and frequencies were used to describe nurses’ knowledge levels, knowledge sources, and barriers to pressure ulcer prevention. Results The majority (73%, n = 141) of nurses had inadequate knowledge about pressure ulcer prevention. The mean scores of the test for all participants was 10.84 out of 26 (SD = 2.3, range = 5–17), with the lowest score in themes related to PU etiology, preventive measures to reduce amount of pressure/shear, and risk assessment. In-service training was the second source of education on pressure ulcer, coming after university training. Shortage of staff and lack of time were the most frequently cited barriers to carrying out pressure ulcer risk assessment, documentation, and prevention. Conclusions This study highlights concerns about Jordanian nurses’ knowledge of pressure ulcer prevention. The

    Summary Background Cellulitis (erysipelas) of the leg is a common, painful infection of the skin and underlying tissue. Repeat episodes are frequent, cause significant morbidity and result in high health service costs. Objectives To assess whether prophylactic antibiotics prescribed after an episode of cellulitis of the leg can prevent further episodes. Methods Double-blind, randomized controlled trial including patients recently treated for an episode of leg cellulitis. Recruitment took place in 20 hospitals. Randomization was by computer-generated code, and treatments allocated by post from a central pharmacy. Participants were enrolled for a maximum of 3 years and received their randomized treatment for the first 6 months of this period. Results Participants (n = 123) were randomized (31% of target due to slow recruitment). The majority (79%) had suffered one episode of cellulitis on entry into the study. The primary outcome of time to recurrence of cellulitis included all randomized participants and was blinded to treatment allocation. The hazard ratio (HR) showed that treatment with penicillin reduced the risk of recurrence by 47% [HR 0·53, 95% confidence interval (CI) 0·26–1·07, P = 0·08]. In the penicillin V group 12/60 (20%) had a repeat episode compared with 21/63 (33%) in the placebo group. This equates to a number needed to treat (NNT) of eight participants in order to prevent one repeat episode of cellulitis [95% CI NNT(harm) 48 to ∞ to NNT(benefit) 3]. We found no difference between the two groups in the number of participants with oedema, ulceration or related adverse events. Conclusions Although this trial was limited by slow recruitment, and the result failed to achieve statistical significance, it provides the best evidence available to date for the prevention of recurrence of this debilitating condition.

    Chronic oedema is a common problem in the UK and, given the country's ageing population, the numbers are predicted to rise. In an epidemiological study carried out in Derby, England, researchers found the prevalence of chronic oedema to be 3.99 in every 1000 people, with the prevalence increasing to 10.31 in those aged 65-74 years. Often, patients with untreated chronic oedema will develop an ulceration that can lead to further costs and hospital admissions. The cost of treating chronic wounds has been estimated at £2.3 billion-£3.1 billion a year. It is therefore surprising that given the number of patients living with these problems, there is still a lack of knowledge and skill among nurses when assessing patients with chronic oedema and associated ulceration. This article offers advice for nurses when assessing leg ulcers in patients with chronic oedema, detailing the visual skin changes most frequently seen in these patients. The article also discusses some of the treatment options available, briefly covering the advantages and disadvantages of each option.

    The chronic venous leg ulcer is the major therapeutic problem of lower limb injuries, which can trigger changes in the daily life of the person affected by it. This study aimed to understand the daily life of men who lives with chronic venous ulcers. A phenomenological study was conducted with eight men, who were interviewed during June and July of 2001. The study asked questions related to: "Restrictions in social life" and "Recovering the skin integrity and restart the activities affected by the wound". The answers revealed that men with these ulcers have social implications in the areas of productivity and sexuality. This leads to restrictions in everyday life with loss in performance of socially established roles for men, leading to anxiety for his return at full performance of his social role. The findings suggest significant experiential aspects that may guide professionals in the planning and implementation of health actions aimed to treat these patients.

    The quality of life (QoL) in patients with advanced venous insufficiency (including venous stasis ulcers, skin discoloration, stasis eczema, and lipodermatosclerosis) assessed using the Clinical Etiological Anatomical Pathophysiological (CEAP) and Venous Clinical Severity Score (VCSS) classifications is presented. Also, disease features such as: intensity of pain, edema and inflammatory response that exerted the most profound effect on different domains of QoL are reported. The global QoL in patients with lower leg venous ulcerations was relatively similar to that observed in other patients with chronic venous insufficiency. The presence of venous ulcerations was associated with lower QoL in a Physical domain. Significant correlations were found between pain intensity and the values of Physical, Physiological, Level of Independence and Environmental domains, between edema intensity and Social domain as well as between the intensity of inflammatory response and Physical and Spiritual domains.

  19. Corneal cross-linking in 9 horses with ulcerative keratitis

    PubMed Central

    2013-01-01

    Background Corneal ulcers are one of the most common eye problems in the horse and can cause varying degrees of visual impairment. Secondary infection and protease activity causing melting of the corneal stroma are always concerns in patients with corneal ulcers. Corneal collagen cross-linking (CXL), induced by illumination of the corneal stroma with ultraviolet light (UVA) after instillation of riboflavin (vitamin B2) eye drops, introduces crosslinks which stabilize melting corneas, and has been used to successfully treat infectious ulcerative keratitis in human patients. Therefore we decided to study if CXL can be performed in sedated, standing horses with ulcerative keratitis with or without stromal melting. Results Nine horses, aged 1 month to 16 years (median 5 years) were treated with a combination of CXL and medical therapy. Two horses were diagnosed with mycotic, 5 with bacterial and 2 with aseptic ulcerative keratitis. A modified Dresden-protocol for CXL could readily be performed in all 9 horses after sedation. Stromal melting, diagnosed in 4 horses, stopped within 24 h. Eight of nine eyes became fluorescein negative in 13.5 days (median time; range 4–26 days) days after CXL. One horse developed a bacterial conjunctivitis the day after CXL, which was successfully treated with topical antibiotics. One horse with fungal ulcerative keratitis and severe uveitis was enucleated 4 days after treatment due to panophthalmitis. Conclusions CXL can be performed in standing, sedated horses. We did not observe any deleterious effects attributed to riboflavin or UVA irradiation per se during the follow-up, neither in horses with infectious nor aseptic ulcerative keratitis. These data support that CXL can be performed in the standing horse, but further studies are required to compare CXL to conventional medical treatment in equine keratitis and to optimize the CXL protocol in this species.

    Last year was not a banner year for developments in medical therapy for ulcerative colitis. In contrast to the expansion of therapies for Crohn disease, treatment for ulcerative colitis was evolutionary, at best, leading many patients to seek alternative medical approaches. Nevertheless, there have been advances in the application of aminosalicylates and immune modifiers for ulcerative colitis. Additional, nonconventional approaches include nicotine, probiotics, dietary therapies, and heparins. Several novel approaches have arisen from animal models, including additional means of inhibiting nuclear factor-kappaB and targeting of tumor necrosis factor-alpha.

Cigarette smoking, intake of alcohol, coffee, mate, aspirin and NSAID were recorded, but there were no significant differences between the two groups. Personality traits were determined by the Rorschach Test, considering psychological profile (introversive, extroversive, self-restrained), impulse and emotion control (do not allow their expression, impulsive, adequately conveyed) and level of social adaptation (low, normal, high). U and NU subjects experienced a similar number of potentially stressful life events. However, U patients perceived their events more negatively. Although no one type of "ulcer personality" was found consistently, ulcer patients tended to be more introversive and they had a better social adaptation than NU.

    Non-Helicobacter pylori, non-NSAID peptic ulcer disease (PUD), termed idiopathic PUD, is increasing in Korea. Diagnosis is based on exclusion of common causes such as H. pylori infection, infection with other pathogens, surreptitious ulcerogenic drugs, malignancy, and uncommon systemic diseases with upper gastrointestinal manifestations. The clinical course of idiopathic PUD is delayed ulcer healing, higher recurrence, higher re-bleeding after initial ulcer healing, and higher mortality than the other types of PUD. Genetic predisposition, older age, chronic mesenteric ischemia, cigarette smoking, concomitant systemic diseases, and psychological stress are considered risk factors for idiopathic PUD. Diagnosis of idiopathic PUD should systematically explore all possible causes. Management of this disease is to treat underlying disease followed by regular endoscopic surveillance to confirm ulcer healing. Continuous proton pump inhibitor therapy is an option for patients who respond poorly to the standard ulcer regimen.

    The aim of this study was to determine the prevalence, severity, location, aetiology, treatment and healing of medical device-related pressure ulcers (PUs) in intensive care patients for up to 7 days. A prospective repeated measures study design was used. Patients in six intensive care units of two major medical centres, one each in Australia and the USA, were screened 1 day per month for 6 months. Those with device-related ulcers were followed daily for up to 7 days. The outcome measures were device-related ulcer prevalence, pain, infection, treatment and healing. Fifteen of 483 patients had device-related ulcers and 9 of 15 with 11 ulcers were followed beyond screening. Their mean age was 60·5 years, and most were men, overweight and at increased risk of PU. Endotracheal (ET) and nasogastric (NG) tubes were the cause of most device-related ulcers. Repositioning was the most frequent treatment. Four of 11 ulcers healed within the 7-day observation period. In conclusion, device-related ulcer prevalence was 3·1%, similar to that reported in the limited literature available, indicating an ongoing problem. Systematic assessment and repositioning of devices are the mainstays of care. We recommend continued prevalence determination and that nurses remain vigilant to prevent device-related ulcers, especially in patients with NG and ET tubes.

    Although gastric ulcers have been identified relatively frequently in racing Thoroughbreds, there have been no large scale studies to determine their effect on health and performance. Two hundred and two Thoroughbred horses in active race training were selected by the attending veterinarians for gastro-endoscopic examination. Images of the stomach mucosa were stored in a digitised format for subsequent evaluation. The number of ulcers and a score of severity were determined. Gastric ulceration of the squamous mucosa was identified in 82% of horses. Seventy-three (39%) horses displayed clinical signs consistent with gastric ulceration. Increasing Furr and Murray Score was associated with poor hair coat (P = 0.03), colic (P = 0.03), and increasing serum creatinine concentration (P = 0.029). There were no associations between haematology and serum biochemistry values (other than serum alkaline phosphatase concentration and serum creatinine concentration) and gastric ulceration. Our study confirmed the relatively high incidence of gastric ulceration in Thoroughbred horses involved in active race training. Gastric ulceration is a potential, but rare, cause of overt colic, but may produce more subtle detrimental effects on a horse's condition. It is concluded that the diagnosis of gastric ulceration should be based on an endoscopic examination of the stomach, although future studies are required to elucidate further the aetiology and clinical significance of gastric ulceration.

    The restless legs syndrome (RLS) is a clinical diagnosis based on the four essential criteria defined by the International Restless Legs Syndrome Study Group (IRLSSG). An idiopathic form can be separated from a symptomatic form. Neurophysiological studies have investigated the pathophysiology of the idiopathic RLS or have been used to exclude a symptomatic cause, in particular polyneuropathy. So far cortical excitability changes, corticomotor, somatosensory and auditory pathways, spinal cord excitability, B-wave rhythm and cycling alternating pattern, as well as reflex mechanisms have been investigated by electroencephalography, evoked potentials, Bereitschaftspotentials, nerve conduction and thermal threshold measurements, electromyography, transcranial Doppler sonography, measurements of the spinal flexor reflex as well as neuroimaging techniques. The etiology of the RLS cannot be revealed by these methods, neurophysiological studies in RLS are, however, useful for a better understanding of the pathophysiology and for exclusion of a polyneuropathy or other symptomatic causes. In addition to neurophysiological investigations, small fiber neuropathy, which seems to be a more common finding in RLS patients than expected to date, may need biopsy for confirmation. This review will focus on investigations of the different systems involved with diverse neurophysiological methods.

    The aim of this study was to determine the rate of venous ulcer recurrence and the level of compliance in patients wearing European class 1 or class 2 compression stockings. A total of 100 patients with healed venous leg ulcers were recruited, and were randomised to either class 1 (n = 50) or class 2 (n = 50) compression stockings. Follow-up was at 1 week, 3, 6, 9 and 12 months to monitor ulcer recurrence and compliance. Patients had a duplex scan to identify the source of venous incompetence. The rate of ulcer recurrence after 12 months was 16·1%, and the difference in recurrence rate between classes was not statistically significant (P = 0·287) although greater numbers in class 1 developed a recurrence. Participants (88·9%) were compliant; non-compliant patients were at a significantly greater risk of recurrence (P≤ 0·0001). Thirteen patients had both superficial and deep incompetence; those randomised to class 1 stockings (n = 4) developed ulcer recurrence. Patients with a history of multiple episodes of ulceration were more likely to develop a recurrence (P = 0·001). The lowest venous ulcer recurrence rates were seen in patients who were compliant with hosiery regardless of the compression level. Patients with both superficial and deep incompetence had a lower rate of recurrence with class 2 compression.

    The definition of a pressure ulcer remains very academic. It results from tissue necrosis following ischemia through prolonged arteriolar constriction between two hard surfaces progressing in stages. The nursing care and the use of dressings are therefore adapted to each stage. Today, the treatment of pressure ulcers is complex due to the large number of categories of dressings available. Moreover, the choice of the dressing must take into account the specificities of elderly patients. However, certain basic principles remain essential.

    Different side effects of drugs have been described in the oral cavity, including oral ulcerations. Direct contact between drugs and oral mucosa may induce chemical burn or local hypersensitivity. Less frequently, these drug-induced oral ulcerations are part of a complex reaction with cutaneous or systemic manifestations. Sometimes, one or more oral ulcerations appear as the main side-effect of a drug, or exceptionally as solitary lesions. Solitary oral ulcerations usually appear after few weeks of treatment. In most of cases, these lesions resist to conventional treatments, with a rapid healing following the suppression of the responsible drug. This diagnosis is usually difficult, particularly with patients receiving multiple drug therapy. Besides, special attention must be paid to new drugs. Oral ulcerations following symptoms of burning mouth, metallic taste, dysgueusia or agueusia are strongly suggestive of a pharmacological origin. Most of the molecules able to induce solitary oral ulcerations are commonly prescribed in a) rheumatology: NSAI (diclofenac, flurbiprofen, indomethacin, naproxen), long-term rheumatoid arthritis therapy (azathioprine, methotrexate, penicillamine, gold compounds, tiopronin); b) cardiology: angiotensin-converting-enzyme inhibitors (captopril, enalapril), angiotensin 2-receptor antagonist (losartan), anti-angorous (nicorandil), c) psychiatry: antidepressants (fluoxetine, lithium), d) AIDS therapy (foscarnet, zalcitabine).

    PubMed

    Love, Jack W

    2008-01-01

    Evidence is reviewed that Helicobacter pylori infection may cause a deficiency of the hormone secretin that allows peptic ulcer disease to develop by impairing the body's defenses to gastric acid. Secretin is released into the circulation from the S-cells of the duodenal crypts in response to gastric acid entering the duodenum. Once in the circulation, secretin has five well-documented effects that protect the upper intestine from gastric acid: it stimulates secretion of bicarbonate rich exocrine pancreatic juice; it stimulates secretion of alkaline bile; it stimulates secretion of alkaline mucus from the duodenal submucosal glands of Brunner; it inhibits the humoral phase of gastric secretion; and it inhibits gastric motility, thereby delaying gastric emptying. Impaired secretin release and reduced duodenal S-cells have been documented in peptic ulcer patients compared with control patients. Clinical evidence that patients with H. pylori infection and peptic ulceration have increased gastric secretion and motility and decreased duodenal bicarbonate response to gastric acid, all of which normalize after eradication of the infection, could be explained by reversible impairment of the secretin mechanism. Gastric metaplasia in the duodenum with H. pylori infection is known to reduce the S-cell population. The fact that not all patients with H. pylori infection develop peptic ulceration suggests that degree of secretin deficiency determined by extent of the infection must reach a critical level for peptic ulceration to occur. Peptic ulceration may be a hormonal deficiency disease, a result of secretin deficiency caused by H. pylori infection. It may be the first example of a specific hormonal deficiency disease caused by a specific bacterial infection.

    Peptic ulcer is one of the most prevalent diseases in gastrointestinal field. Recently, evolution was made for pathophysiology of peptic ulcer from "no acid, no ulcer" to Helicobacter pylori and non-steroidal anti-inflammatory drugs. The prevalence of peptic ulcer disease is estimated about 10% in Korea, and has declined due to Helicobacter pylori eradication therapy. Peptic ulcer has the cycle of exacerbation and improvement in the clinical course, and has not occasionally any clinical symptom. Helicobacter pylori eradication has made the marked reduction of relapse of peptic ulcer disease. Although nationwide endoscopic screening has enabled accurate diagnosis of peptic ulcer disease, general guideline for diagnosis of peptic ulcer has not made in Korea. Herein, we propose a guideline for the diagnosis of peptic ulcer according to domestic, international clinical studies, and experts opinions with level of evidence and grade of recommendation.

    Authors in this article present etiology, clinical manifestations, diagnostic procedures and treatment of peptic ulcer disease in children and adults. Increased gastric acid output, Helicobacter pylori, NSAIDs and stress are the basic risk factors in peptic ulcer disease. H. pylori infection is a widely known risk factor in peptic ulcer disease and influences diagnostic and treatment procedures. Primary ulcer disease concerns mainly duodenum and is accompanied by H. pylori infection. Gastroscopy and Helicobacter tests are the only reliable procedures to diagnose peptic ulcer disease. Nowadays the most important aim in peptic ulcer treatment is the H. pylori eradication. Therapy with two antibiotics and a protein pomp inhibitor eradicates the bacteria, treats the ulceration and lowers the number of ulcer recurrence. In non-infected H. pylori ulcers or in a long-term treatment protein pomp inhibitors and H2-inhibitors are effective as well in gastroprotective therapy.

    Pain radiated from the chest to one or both legs (17 cases), or from the legs to the chest (two cases) in 19 patients with angina or acute myocardial infarction. The leg pain was assumed to be related to the angina pectoris when both were of a similar character and occurred together, when the leg pain occurred at rest, and when there were normal peripheral pulses in the leg. Pain was felt in the left leg by 10 patients, the right leg by two patients, and in both legs by seven. Three patients experienced pain in the thigh(s), six in the shin(s), and 10 had pain in both. In six patients the pain extended down to the inner two to four toes. The pain was always felt in front of the legs. This distribution accords with the suggestion that some sensory cardiac nerve fibres occur in the lumbar sympathetic ganglia and that pain is projected into the corresponding dermatomes.

    The mechanisms that govern fluid uptake by the initial lymphatics and adjustment of lymph flow rates remain to a large degree uncertain. The aim of this study was to examine how passive tissue movement contributes to lymph flow rates. Lymph fluid was collected via a cannula inserted into one of the popliteal prenodal lymphatics in the rabbit hind leg. Lymph flow rates were measured during periodic whole leg rotation and controlled oscillatory massage of the dorsal skin of the foot. Without whole leg rotation, lymph flow remained at low values (< 0.01 ml/h). Introduction of whole leg passive rotation caused a frequency-dependent increase in lymph flow rates, which were increased linearly with the log of frequency between 0.03 and 1.0 Hz. Local skin massage in the region of the initial lymphatics also led to a similar increase of lymph flow rates dependent on frequency as well as amplitude of skin displacement. Lymph flow rates during local skin massage reached a comparable order of magnitude regardless of whether the animal was alive or the heart had been arrested, suggesting that local lymph flow rates can be adjusted by periodic tissue motion independently of capillary fluid filtration pressures. The results indicate that periodic expansion and compression of initial lymphatics provide a mechanism for lymph pumping.

  15. Space Elevator Base Leg Architecture

    Swan, C.; Swan, P. A.

    While the Space Elevator stretches for 104,000 kilometers, the region of most concern, from the survival perspective, is 2,500 kms and below. The threats inside this dangerous arena include debris, spacecraft, meteorites, lightening, winds, rogue waves, aircraft, and intentional human acts. Two major questions will be addressed that will influence the overall systems architecture of a Space Elevator. While the deployment phase of the development of the Space Elevator will only have a single ribbon from the surface of the Earth to well beyond the Geosynchronous altitude, a mature Space Elevator must never allow a complete sever of the system. Design approaches, materials selections, international policy development and assembly must ensure that the integrity of the Space Elevator be maintained. The trade space analysis will address the probability of an individual ribbon being severed, the length of time to repair, and the potential for a catastrophic Space Elevator cut. The architecture proposed for the base leg portion will address two questions: Shall there be multiple base legs to 2,500 kms altitude? And Should the anchor be based on land or at sea?

    Recent studies indicate that human locomotion is quadrupedal in nature. An automatic rhythm-generating system is thought to play a crucial role in controlling arm and leg movements. In the present study, we attempted to elucidate differences between intrinsic arm and leg automaticity by investigating cadence variability during simultaneous arm and leg (AL) cycling. Participants performed AL cycling with visual feedback of arm or leg cadence. Participants were asked to focus their attention to match the predetermined cadence; this affects the automaticity of the rhythm-generating system. Leg cadence variability was only mildly affected when the participants intended to precisely adjust either their arm or leg cycling cadence to a predetermined value. In contrast, arm cadence variability significantly increased when the participants adjusted their leg cycling cadence to a predetermined value. These findings suggest that different neural mechanisms underlie the automaticities of arm and leg cycling and that the latter is stronger than the former during AL cycling.

    Lipschütz ulcer is an uncommon entity that is clinically characterised by a flu-like syndrome accompanied by an acute painful necrotic vulvar ulcer. It typically occurs in young women with no sexual contact history, and it is very rare among children. The aetiology is unknown, although recently several reports have related Epstein-Barr virus primary infection with this entity. We report a 17-month-old girl with fever and an acute genital ulcer. All the complementary tests for the most frequent causes of vulvar ulcers yielded negative results, whereas viral serology and polymerase chain reaction technique confirmed the presence of an acute Epstein-Barr virus infection. When main causes of genital ulcer have been excluded, and there is no history of sexual contact, Lipschütz ulcer should be included in the differential diagnosis. Detection of Epstein-Barr virus genome by polymerase chain reaction can lead to an earlier diagnosis.

    Introduction Helicobacter pylori (H. pylori) occurs throughout the world and causes gastroduodenal diseases. There is data indicating a change in the prevalence of H. pylori infection worldwide. The prevalence of H. pylori is 80% in Turkey, while it is higher in many developing countries, and the rate of infection varies throughout the world. In many developing countries, the prevalence of infection exceeds 90% by adulthood. Aim To determine the change in the rate of H. pylori infection in gastric ulcers and duodenal ulcers for a 10-year period in a single centre. Material and methods The study population included 550 patients (342 in 2004, 208 in 1994) with gastric and duodenal ulcers. Results In 2004 there were 125 (36.5%) patients with gastric ulcer and 217 patients with duodenal ulcer (64.5%). CLO test positivity was 39.2% in patients with gastric ulcers and 60% in patients with duodenal ulcers. In 1994 there were 208 patients (159 duodenal ulcers, 49 gastric ulcers). Urease test was positive in 74.2% of patients with duodenal ulcer and in 65.2% of patients with gastric ulcer. The decrease in the rate of urease positivity in patients with gastric ulcer was statistically significant (p = 0.01) during this 10-year period. Conclusions In the present study we found that the urease positivity decreased significantly in patients with gastric ulcer between 1994 and 2004. PMID:26516382

    Two women with advanced human immunodeficiency virus infection are described who were seen with painful aphthous vaginal ulceration and CD4+ lymphocyte counts < 50 cells/mm3. A chronic rectovaginal fistula developed in one patient. In spite of extensive investigation no underlying cause of the ulceration was discovered. Clinical therapeutic response suggests that corticosteroid therapy may be of value in healing or stabilizing the destructive process. Clinicians should be aware of this complication in human immunodeficiency virus-infected women with severe vaginal pain and unexplained discharge.

    Myxoma induces the onset of paraneoplastic syndromes by excreting various humoral mediators and is therefore known to present with diverse symptoms. A 40-year-old woman was admitted to our hospital for the treatment of an esophageal ulcer, the cause of which could not be identified on various examinations. Notably, a left atrial tumor was incidentally found on chest enhanced computed tomography. The esophageal ulcer, which was intractable to conventional therapy, improved with the administration of 5-aminosalicylate, a drug known to inhibit IL-1β. This inhibitory action effectively suppressed the development of myxoma-induced paraneoplastic syndrome.

    2015-01-01

    An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

    Background: Several synthetic drugs are useful in the treatment of peptic ulcer, but almost of these drugs are used in prolonging time, it may cause several adverse reactions. However, the herbal medicines are more potent to the treatment and minimize the side effects. Objective: To evaluate the methanol extract of Jatropha gossypiifolia Linn. (MEJG) for gastro protective activity against Wistar rats. Materials and Methods: Anti-ulcer potency of MEJG (100 and 200 mg/kg, b.w.) was assessed using aspirin (200 mg/kg, p.o.) plus pylorus ligation ulcer model and the parameters studied were ulcer index (UI), gastric juice volume, pH, total acidity, and total acid output. Same extract was studied by ethanol-induced (80%, 5 mL/kg, intragastrically) ulcer model, and the UI and biochemical parameters were studied. Results: The oral administration of MEJG (100 and 200 mg/kg) significantly (P < 0.001) attenuated the ulcer score and anti-secretary parameters (such as the volume of gastric content, free acidity, total acidity, and total acid output) in the aspirin plus pylorus ligation rats. The extract also significantly attenuated (P < 0.001) ulcer score in ethanol-induced ulcer model and lipid peroxidation level and significantly increased the level of glutathione peroxides, catalase, and superoxide dismutase activity. The MEJG may possess active constituents such as alkaloids, glycosides, flavonoids, and terpenes, which may play a major role in gastroprotective effect in Wistar rats. Conclusion: The present study provides scientific support for the anti-ulcer activities of extracts of JG and also claimed that antioxidant potential of the extracts. However, substantiates the traditional claims for the usage of this drug in the treatment of gastric ulcer. SUMMARY The methanolic extract of jatropha gossypiifolia Linn. for gastro protective activity against aspirin plus pyloric ligation and ethanol induced ulcer models was studied in Wistar rats.

    There is a high mortality in patients with diabetes and severe pressure ulcers. For example, chronic pressure sores of the heels often lead to limb loss in diabetic patients. A major factor underlying this is reduced neovascularization caused by impaired activity of the transcription factor hypoxia inducible factor-1 alpha (HIF-1α). In diabetes, HIF-1α function is compromised by a high glucose-induced and reactive oxygen species-mediated modification of its coactivator p300, leading to impaired HIF-1α transactivation. We examined whether local enhancement of HIF-1α activity would improve diabetic wound healing and minimize the severity of diabetic ulcers. To improve HIF-1α activity we designed a transdermal drug delivery system (TDDS) containing the FDA-approved small molecule deferoxamine (DFO), an iron chelator that increases HIF-1α transactivation in diabetes by preventing iron-catalyzed reactive oxygen stress. Applying this TDDS to a pressure-induced ulcer model in diabetic mice, we found that transdermal delivery of DFO significantly improved wound healing. Unexpectedly, prophylactic application of this transdermal delivery system also prevented diabetic ulcer formation. DFO-treated wounds demonstrated increased collagen density, improved neovascularization, and reduction of free radical formation, leading to decreased cell death. These findings suggest that transdermal delivery of DFO provides a targeted means to both prevent ulcer formation and accelerate diabetic wound healing with the potential for rapid clinical translation.

    This article reviews the mechanism, symptoms, causes, severity, diagnosis, prevention and present recommendations for surgical as well as non-surgical management of pressure ulcers. Particular focus has been placed on the current understandings and the newer modalities for the treatment of pressure ulcers. The paper also covers the role of nutrition and pressure-release devices such as cushions and mattresses as a part of the treatment algorithm for preventing and quick healing process of these wounds. Pressure ulcers develop primarily from pressure and shear; are progressive in nature and most frequently found in bedridden, chair bound or immobile people. They often develop in people who have been hospitalised for a long time generally for a different problem and increase the overall time as well as cost of hospitalisation that have detrimental effects on patient's quality of life. Loss of sensation compounds the problem manifold, and failure of reactive hyperaemia cycle of the pressure prone area remains the most important aetiopathology. Pressure ulcers are largely preventable in nature, and their management depends on their severity. The available literature about severity of pressure ulcers, their classification and medical care protocols have been described in this paper. The present treatment options include various approaches of cleaning the wound, debridement, optimised dressings, role of antibiotics and reconstructive surgery. The newer treatment options such as negative pressure wound therapy, hyperbaric oxygen therapy, cell therapy have been discussed, and the advantages and disadvantages of current and newer methods have also been described.

    Haemophilus ducreyi causes the sexually transmitted genital ulcer disease chancroid. In human inoculation experiments, bacteria colocalize with neutrophils and macrophages but remain extracellular. The organism also colocalizes with collagen and fibrin but not with keratinocytes, fibroblasts, laminin, or fibronectin. These relationships are established by 48 h postinoculation and persist through the pustular stage of disease. To extend these observations to the ulcerative stage of disease, and to compare results in the human model with those of natural disease, we obtained biopsies from patients with naturally acquired chancroid. All ulcers were culture positive for H. ducreyi and histologically very similar to pustules from the human model. Staining with H. ducreyi-specific monoclonal antibodies demonstrated H. ducreyi within 5 biopsies. The organism was chiefly found within the granulocytic infiltrate of the ulcer. Dual staining for H. ducreyi and eukaryotic tissue components showed that H. ducreyi colocalized with neutrophils and fibrin at the ulcerative stage of disease. No bacteria were associated with keratinocytes, fibroblasts, or collagen. Overall, these findings are consistent with results from the human model. This is the first reported study to localize bacteria specifically identified as H. ducreyi within naturally acquired chancroid.

  9. The limitations of current therapy in peptic ulcer disease.

    PubMed

    Salena, B J; Hunt, R H

    1987-05-01

    The current therapeutic approach to peptic ulcer disease includes agents that reduce gastric acidity and hence peptic activity, inactivate or adsorb pepsin, create a physical barrier against the effects of acid and pepsin, or enhance mucosal defence. Profound gastric acid reduction may predispose to infection, and it has been suggested that carcinogenesis is possible, although a cause-effect relationship has never been established. The side-effects of therapy are well-described, and may limit the therapeutic approach. Healing rates correlate closely with acid suppression in duodenal ulcer, but not entirely in gastric ulcer. Maintenance therapy lowers the relapse rate, but does not alter the ulcer diathesis. The optimal strategy for long-term management remains unclear, but in the future one should consider outcome measures which include a decrease in pain, improvement in the quality of life, reduction work loss, and a reduction of complications, in addition to ulcer healing. The ideal therapy should be efficacious, safe, and convenient--with no side-effects--and cost-effective. New agents should suppress acid and peptic activity, while enhancing the gastric mucosal defence mechanisms (such as mucosal blood flow, mucus, and bicarbonate secretion) and stimulating gastric cellular regeneration and restitution.

    Isobutyl cyanoacrylate tissue adhesive (BCTA) was used in the treatment of refractory superficial corneal ulcers in 17 dogs, one cat, and one rabbit, present 2 weeks to 7 months (mean 6.8 weeks +/- 6.1) prior to referral. Little to no sedation was required in the majority of cases, with only topical anesthetic applied prior to debridement and BCTA application. The presence of the tissue adhesive caused mild discomfort for several days after application, as reported by the owners. The ulcers healed, and the tissue adhesive sloughed in approximately 3 weeks (+/- 1 week). Mild neovascularization of the cornea resolved with topical corticosteroids. The use of BCTA offers a simple, safe and noninvasive treatment for refractory corneal ulcers.

    Diabetic foot ulcers remain a major cause of morbidity. Significant progress has been accomplished in ulcer healing by improved management of both ischemia and neuropathy in the diabetic foot. Nevertheless, there is a vital need for further improvement. Becaplermin gel represents an important therapeutic advance for diabetic neuropathic foot ulcers with adequate blood supply. Randomized controlled trials have shown that it is effective in increasing healing rates. However, this efficacy has not translated to positive clinical experience, and the drug is not widely used. Moreover, becaplermin is an expensive medication. Even though it has repeatedly been estimated as cost-effective, its high cost may be prohibitive for some clinicians, especially in developing countries. Clearly, further work is needed to clarify whether use of becaplermin is justified in everyday clinical practice. Future research also needs to assess the potential room for improvement with becaplermin, for instance by combination with other growth factors or by exploring alternative modes of drug delivery.

A pressure ulcer is a lesion located in skin I underlying tissue usually over a bone prominence, as a result of the pressure, or pressure in combination with the shears. A number of contributing factors or confounding factors are also associated with ulcers by pressure; the importance of these factors still not been elucidated. The heels are next to the sacred area, parts of the body that most frequently presents ulcers by pressure, The importance of the predisposing factors for ulcers in the sacral area as humidity has been studied in recent years, but in heels, remains one of the most important locations in the extremities, which entails adverse outcomes such as amputation in persons with comorbid diseases like Diabetes Mellitus (DM). The incidence of ulcers on heels in patients with DM and without it, is approximately 19-32%. Everything and be a problem associated with elderly people and chronic pathologies, in acute patients are a problem that this underrated, but not devoid of controversy. In hospitals of treble in 2006, the NPUAP encrypted the incidence of UPPin heels in a 43%; in one systematic review conducted by Reddy et al. (2006) puts revealed that 60% of pressure ulcers is produced. The problem of the UPP in heels is present in all the areas of intervention and particularly in paediatric units intensive care, where the first localization it is the occipital area followed by the heels.

    Painless legs and moving toes is an unusual syndrome, which has not previously been reported as an initial presentation of ischemic stroke. We encountered a 78-year-old woman who developed dysarthria and involuntary movement of her left toes that was clinically regarded as painless legs and moving toes. These symptoms appeared abruptly and simultaneously as the initial symptoms of stroke, and improved gradually with conservative management by intravenous hydration for a month. We suggest that, in our case, a cortical brain lesion caused by ischemic stroke might be associated with the development of painless legs and moving toes.

    Context Long-distance running (greater than 3000 m) is often recommended to maintain a healthy lifestyle. Running injury rates increase significantly when weekly mileage extends beyond 40 miles cumulatively. With the development of running analysis and other diagnostic tests, injuries to the leg secondary to bone, musculotendinous, and vascular causes can be diagnosed and successfully managed. Evidence Acquisition Searches used the terms running, injuries, lower extremity, leg, medial tibial stress syndrome, compartment syndrome, stress fractures, popliteal artery entrapment, gastrocnemius soleus tears, and Achilles tendinopathy. Sources included Medline, Google Scholar, and Ovid from 1970 through January 2012. Results Tibial stress fractures and medial tibial stress syndrome can sometimes be prevented and/or treated by correcting biomechanical abnormalities. Exertional compartment syndrome and popliteal artery entrapment syndrome are caused by anatomic abnormalities and are difficult to treat without surgical correction. Conclusion Leg pain due to bone, musculotendinous, and vascular causes is common among long-distance runners. Knowledge of the underlying biomechanical and/or anatomic abnormality is necessary to successfully treat these conditions. PMID:24179587

This condition can be idiopathic or secondary to infection, thromboembolic states, neoplasm, or connective tissue disease. The characteristic lesions of cryofibrinogenemia include purpura and ulcerations. Histologically, the lesions of cryofibrinogenemia demonstrate fibrin thrombi within vessels, with no evidence of vasculitis. Treatment of cryofibrinogenemia should be directed at the underlying disease process, if one can be found. Other treatments have included the anabolic steroid stanozolol, which is presently unavailable, anticoagulants, immunosuppressive agents, plasmapheresis, and the combination of streptokinase and streptodornase. We report a case of a 61-year-old male smoker with a 10-year history of intermittent ulcerations of both legs and feet. Two separate biopsies showed epidermal ulceration and thrombi within superficial dermal vessels without evidence of vasculitis. These findings, together with the presence of elevated plasma cryofibrinogen, led to the diagnosis of cryofibrinogenemia. The patient continued to have ulcerations despite efforts to control his high blood pressure, cold avoidance, local wound care, and treatment with pentoxifylline 800 mg three times daily. However, when colchicine 0.6 mg twice daily was added to the patient's care, this led to rapid healing of his ulcerations. He has remained ulcer free for 2 years taking the combination of colchicine and high-dose pentoxifylline. Efforts to reduce the dose of these agents have repeatedly led to recurrences, and remission has promptly followed re-establishment of the combination. To our knowledge, this is the first report documenting use of the combination of colchicine and high-dose pentoxifylline to successfully treat ulcers due to cryofibrinogenemia.

    To observe the efficacy of intra-arterial chemotherapy with subcutaneously implanted pump for soft tissue sarcoma in extremities and cancerous ulcer. 31 patients with ulcerative skin squamous cell carcinoma or sarcoma in extremities who received treatment during the period from July 2003 to November 2011 at our hospital were recruited, including 15 male and 16 female patients, aging between 14 and 83 with average age of 49 years old. 10 patients had tumor in upper extremities and 21 patients in lower extremities. The pathological types of studied cases include 9 cases with skin squamous cell carcinoma, 6 cases with synovial sarcoma, 5 cases with malignant fibrous histiocytoma, 3 cases with liposarcoma, 3 cases with osteosarcoma, 2 cases with malignant melanoma, 2 cases with epidermoid sarcoma, and 1 case with protuberans. The main symptoms of cancerous ulcer were pain, infection and hemorrhage; All the studied patients were administrated with cisplatin and doxorubicin by intra-arterial chemotherapy pump, and the patients with squamous cell carcinoma were additionally applied with bleomycin and patients with malignant melanoma were additionally applied with dacarbazine. The chemotherapy efficiency was observed after at 3 cycles of intra-arterial chemotherapy. The total remission rate of pain (RR) was 87 %, and total remission rate of ulcer cicatrization (RR) was 71 %, with ulcer cicatrizing spontaneously in 9 cases and obvious homeostasis in 5 cases with bleeding ulcers. 19 patients underwent surgery after chemotherapy, in which 16 cases had limb-salvage surgery and 3 cases underwent lower leg amputation after chemotherapy, and 3 patients out of 16 cases had local recurrence (19 %). The subcutaneous intra-arterial targeting chemotherapy could be applied to treat refractory sarcoma and cancerous ulcer in extremities to significantly increase the chemotherapeutic concentration at tumor area so as to effectively constrain the tumor rupture induced main symptoms

    (1) The restless legs syndrome consists of unpleasant sensory and motor symptoms of varying intensity in the lower limbs. Symptoms occur at rest, seated or lying down, are more intense in the evening and at night, and are relieved by moving the limb. This syndrome does not cause serious physical complications. When sleep disturbances occur, non drug methods should be tried first. (2) Ropinirole is a dopaminergic agonist initially marketed for the treatment of Parkinson's disease. It is the first drug to be approved for restless legs syndrome in France. (3) Three double-blind randomised placebo-controlled trials with similar designs showed minimal differences on a composite rating scale. After 12 weeks of treatment, ropinirole led to an improvement of about 3 points on a 40-point scale compared with placebo. (4) A 12-week double-blind randomised controlled trial and including patients who had "responded" to ropinirole showed a lower relapse rate in the group that continued to use ropinirole (32.6%) instead of switching to placebo (57.8%). However, we do not know if this was because of continued drug efficacy or a rebound effect in the placebo group. (5) The adverse effects of ropinirole in patients with restless legs syndrome had already been observed in the treatment of Parkinson's disease, and included nausea, vomiting, drowsiness, a sudden urge to sleep, syncope, hypotension, and hallucinations. (6) An increase in the severity of restless legs symptoms, typically seen with levodopa, was not evaluated in clinical trials of ropinirole. Some cases have nevertheless been reported. They describe the appearance of symptoms increasingly early in the evening, then in the afternoon, or as a rebound effect in the morning or the latter part of the night. Their intensity increases and can affect other parts of the body. (7) In practice, ropinirole has a negative risk-benefit balance in restless legs syndrome, which is a minor health disorder.

    2016-04-01

    Preventing pressure ulcers is one of the most challenging goals existing for today's health care provider. Currently used tools which assess risk of pressure ulcer development rarely evaluate the accuracy of predictability, especially in older adults. The current study aimed at providing a systemic review and meta-analysis of 29 studies using three pressure ulcer risk assessment tools: Braden, Norton, and Waterlow Scales. Overall predictive validities of pressure ulcer risks in the pooled sensitivity and specificity indicated a similar range with a moderate accuracy level in all three scales, while heterogeneity showed more than 80% variability among studies. The studies applying the Braden Scale used five different cut-off points representing the primary cause of heterogeneity. Results indicate that commonly used screening tools for pressure ulcer risk have limitations regarding validity and accuracy for use with older adults due to heterogeneity among studies.

    A 65-year-old lady presented with recurrent crusting of lips and ulceration on face since the last three weeks. History revealed recurrent herpes labialis during the previous three years. Examination showed hemorrhagic crusting of lips and a solitary crusted ulcer on the right cheek. The patient showed partial improvement with antiviral therapy. On withdrawal of initial therapy, the patient developed classical lesions of herpes labialis and erythema multiforme. Investigations confirmed herpes simplex infection and erythema multiforme. All the lesions including the ulcer on the face responded to maintenance therapy with antivirals. Though herpes infection has been found to cause ulcers especially in the peri-anal region in immunosuppressed individuals, it is the first time in literature that a facial ulcer has been ascribed to herpes simplex virus that too in an immunocompetent individual.

    Bleeding per rectum is an uncommon presentation in pediatric patients. Heterotopic gastric mucosa in the rectum is a rare cause of rectal bleeding. Here, we report a 3-year-old child with a bleeding rectal ulcer that was initially diagnosed and managed as a solitary rectal ulcer syndrome. After 1 month, the patient persisted to have intermittent rectal bleed and severe anal pain. Repeat colonoscopy showed the worsening of the rectal ulcer in size. Pediatric surgeon excised the ulcer, and histopathological examination revealed a gastric fundic-type mucosa consistent with the diagnosis of gastric heterotopia of the rectum. Over the following 18 months, our patient had experienced no rectal bleeding and remained entirely asymptomatic. In conclusion, heterotopic gastric mucosa of the rectum should be considered in the differential diagnosis of a bleeding rectal ulcer.

  3. Why do flamingos stand on one leg?

    PubMed

    Anderson, Matthew J; Williams, Sarah A

    2010-01-01

    A series of observational studies of captive Caribbean flamingos Phoenicopterus ruber were conducted to determine why flamingos rest on one leg. While frequently asked by the general public, this basic question has remained unanswered by the scientific community. Here we suggest that the latency of flamingos to initiate forward locomotion following resting on one leg is significantly longer than following resting on two, discounting the possibility that unipedal resting reduces muscle fatigue or enhances predatory escape. Additionally, we demonstrate that flamingos do not display lateral preferences at the individual or group levels when resting on one leg, with each bird dividing its resting time across both legs. We show that while flamingos prefer resting on one leg to two regardless of location, the percentage of birds resting on one leg is significantly higher among birds standing in the water than among those on land. Finally, we demonstrate a negative relationship between temperature and the percentage of observed birds resting on one leg, such that resting on one leg decreases as temperature rises. Results strongly suggest that unipedal resting aids flamingos in thermoregulation.

    VOMERO, Nathália Dalcin; COLPO, Elisângela

    2014-01-01

    Introduction Peptic ulcer is a lesion of the mucosal lining of the upper gastrointestinal tract characterized by an imbalance between aggressive and protective factors of the mucosa, having H. pylori as the main etiologic factor. Dietotherapy is important in the prevention and treatment of this disease. Aim To update nutritional therapy in adults' peptic ulcer. Methods Exploratory review without restrictions with primary sources indexed in Scielo, PubMed, Medline, ISI, and Scopus databases. Results Dietotherapy, as well as caloric distribution, should be adjusted to the patient's needs aiming to normalize the nutritional status and promote healing. Recommended nutrients can be different in the acute phase and in the recovery phase, and there is a greater need of protein and some micronutrients, such as vitamin A, zinc, selenium, and vitamin C in the recovery phase. In addition, some studies have shown that vitamin C has a beneficial effect in eradication of H. pylori. Fibers and probiotics also play a important role in the treatment of peptic ulcer, because they reduce the side effects of antibiotics and help reduce treatment time. Conclusion A balanced diet is vital in the treatment of peptic ulcer, once food can prevent, treat or even alleviate the symptoms involving this pathology. However, there are few papers that innovate dietotherapy; so additional studies addressing more specifically the dietotherapy for treatment of peptic ulcer are necessary. PMID:25626944

  6. Potassium Channelopathies and Gastrointestinal Ulceration

    PubMed Central

    Han, Jaeyong; Lee, Seung Hun; Giebisch, Gerhard; Wang, Tong

    2016-01-01

    Potassium channels and transporters maintain potassium homeostasis and play significant roles in several different biological actions via potassium ion regulation. In previous decades, the key revelations that potassium channels and transporters are involved in the production of gastric acid and the regulation of secretion in the stomach have been recognized. Drugs used to treat peptic ulceration are often potassium transporter inhibitors. It has also been reported that potassium channels are involved in ulcerative colitis. Direct toxicity to the intestines from nonsteroidal anti-inflammatory drugs has been associated with altered potassium channel activities. Several reports have indicated that the long-term use of the antianginal drug Nicorandil, an adenosine triphosphate-sensitive potassium channel opener, increases the chances of ulceration and perforation from the oral to anal regions throughout the gastrointestinal (GI) tract. Several of these drug features provide further insights into the role of potassium channels in the occurrence of ulceration in the GI tract. The purpose of this review is to investigate whether potassium channelopathies are involved in the mechanisms responsible for ulceration that occurs throughout the GI tract. PMID:27784845

    On this study, patients with vascular ulceration on the lower legs treated with amniocordal membrane grafts, are analyzed. The graft implantation procedure is also described. This surgical procedure could be made ambulatorily. The results from this study confirm the short time of healing needed by this technique and the immediate release of the symptoms. The results also confirm the simplicity and economy of the technique, which could be carried out at any health level. Patients were distributed into two groups of treatment with similar variables. On the first group, an amniocorial membrane was used. On the second one, the treatment was carried out by the classic way. The resulting chi 2 was highly significant.

    The medical and endoscopic treatment of duodenal ulcer are decreasing the frequency of surgical treatment in this disease. The authors study the operations performed for duodenal ulcer within the period 1989-1999 in the County Hospital Baia Mare. The decrease of the rate of surgical interventions is the pure effect of the medical treatment, as long as the endoscopic treatment is not yet available in our service. The rate of ulcer--induced perforations remained, however, unmodified (48% of total operatory indications), as well as the postoperative morbidity and--mortality (18% respectively 9%). The last category seems not to be influenced by the type of chosen surgical procedure, but by the patient's age, duration of the disease, and associated pathology.

    2004-12-01

    Peptic ulcer disease (PUD) has been reported to occur in children worldwide, but no information is available for our community. The aim of the study was to report our experience on the pattern of this condition in Saudi Arabian children. The records of all children below 18 years of age who were diagnosed by endoscopy to have PUD over a period of 10 years were analysed. From 1993 to 2002, 24 children out of 521(5 per cent) who presented with upper gastrointestinal tract (GIT) symptoms were diagnosed by endoscopy to have PUD. All but one (96 per cent) were Saudi nationals, the average age was 15 years (range 5-18 years), and the male to female ratio was 7:1. The commonest presentation was chronic abdominal pain in 15/24 (63 per cent) of the children, followed by vomiting associated with abdominal pain in four (17 per cent). Hematemesis and melena occurred in three (13 per cent), and two children (8 per cent), respectively. There were 20 duodenal (92 per cent) and four gastric ulcers. The primary type was the most common, occurring in 19 (79 per cent) of the children. Histopathology results of antral biopsies were available for 15 children; all of them had antral gastritis. Helicobacter pylori organisms were present in 13/15 (87 per cent) of the antral biopsy specimens. In Saudi children, peptic ulcer disease occurs more commonly in boys. It is a rare cause of upper GIT symptoms, but highly associated with H. pylori antral gastritis. This study documents a pattern similar to descriptions from other countries.

    This review article examines the available evidence on both the primary and secondary prevention of venous ulceration, exploring both the individual, social and financial implications of system failures that allow patients to remain at increased risk of recurrent ulceration. The role of both venous disease assessment and corrective superficial venous surgery are discussed in the light of recently published randomised controlled studies on the role of superficial venous surgery as both an adjunct to ulcer healing and ulcer prevention.

    Raynaud, digital ulcers and calcinosis are frequent manifestations of patients with systemic sclerosis. Digital ulcers are seen in more than half of the patients with scleroderma. Hospitalizations, ischemic complications and impairment of hand function are frequently observed in patients with digital ulcers, especially if treatment is delayed. Rapid and intensive treatment escalation in patients with scleroderma and refractory Raynaud's phenomenon is one of the most effective preventive action available in order to avoid the development of digital ulcers and tissue loss.

  13. Misoprostol in peptic ulcer disease.

    PubMed

    Watkinson, G; Akbar, F A

    1987-01-01

    Misoprostol, a synthetic prostaglandin E1 (PGE1) methyl ester analog has potent antisecretory and cytoprotective effects on the gastric and duodenal mucosa which should make it an effective drug in the treatment of gastric and duodenal ulcer. In two multicenter, randomised, double-blind, controlled studies involving over 900 patients with endoscopically proven benign gastric ulcer and in six similar studies involving over 2000 patients with active duodenal ulcers, differing doses of misoprostol have been compared with either placebo therapy or with conventional doses of cimetidine. In these studies misoprostol 800 mcg daily given as two or four divided doses has been shown to produce rates of complete ulcer healing and pain relief which were significantly superior to placebo therapy and comparable to those achieved with cimetidine. Drug related adverse effects were infrequent. A dose related diarrhea occurred in a small proportion of patients which seldom necessitated suspension of therapy. Because of the known uterotropic effect of prostaglandins the drug should not be used in pregnant women or women of child bearing age unless they are using adequate contraceptive measures. No clinically significant adverse, hematological or biochemical effects have been reported. Two studies suggested that misoprostol reduced the adverse effect of smoking on the healing of duodenal ulcer. In addition, misoprostol has been shown to protect the gastro-duodenal mucosa from the damaging effects of alcohol and non-steroidal anti-inflammatory drugs. This action may prove of value in the treatment of ulcer patients who are inveterate smokers, alcohol users or who are compelled to consume non-steroidal anti-inflammatory drugs for pain relief from rheumatic and allied diseases.

    Younse, Paulo; Aghazarian, Hrand

    2010-01-01

    The figure depicts selected aspects of a six-legged robot that moves by hopping and that can be steered in the sense that it can be launched into a hop in a controllable direction. This is a prototype of hopping robots being developed for use in scientific exploration of rough terrain on remote planets that have surface gravitation less than that of Earth. Hopping robots could also be used on Earth, albeit at diminished hopping distances associated with the greater Earth gravitation. The upper end of each leg is connected through two universal joints to an upper and a lower hexagonal frame, such that the tilt of the leg depends on the relative position of the two frames. Two non-back-driveable worm-gear motor drives are used to control the relative position of the two frames along two axes 120 apart, thereby controlling the common tilt of all six legs and thereby, further, controlling the direction of hopping. Each leg includes an upper and a lower aluminum frame segment with a joint between them. A fiberglass spring, connected via hinges to both segments, is used to store hopping energy prior to launch into a hop and to cushion the landing at the end of the hop. A cable for loading the spring is run into each leg through the center of the universal joints and then down along the center lines of the segments to the lower end of the leg. A central spool actuated by a motor with a harmonic drive and an electromagnetic clutch winds in all six cables to compress all six springs (thereby also flexing all six legs) simultaneously. To ensure that all the legs push off and land in the same direction, timing- belt pulley drives are attached to the leg segments, restricting the flexing and extension of all six legs to a common linear motion. In preparation for a hop, the spool can be driven to load the spring legs by an amount corresponding to a desired hop distance within range. The amount of compression can be computed from the reading of a shaft-angle encoder that

    2016-01-01

    Gastritis and gastric ulcers are an important cause of morbidity and mortality in canine athletes. Although the majority of scientific work on this condition has been performed in ultraendurance racing sled dogs, this condition has been identified in other canine athletes, including sled dogs competing in shorter events and dogs performing off-leash explosive detection duties. The cause of the syndrome is unknown, but current hypotheses propose a link between exercise-induced hyperthermia and loss of gastric mucosal barrier function as an early event in the pathogenesis. Treatment is focused on prevention of clinical disease using acid secretion inhibitors, such as omeprazole, which has excellent efficacy in controlled clinical studies. PMID:27092307

  3. Recurrent and other new foot ulcers after healed plantar forefoot diabetic ulcer.

    PubMed

    Örneholm, Hedvig; Apelqvist, Jan; Larsson, Jan; Eneroth, Magnus

    2017-04-01

    Diabetic foot ulcer is a serious complication in patients with diabetes. In most outcome studies of this condition, there is a combination of various types of ulcer and ulcer locations. Plantar ulcers are usually localized to the forefoot, and constitute a quarter of all diabetic foot ulcers. There are a limited number of studies regarding development of new ulcers following healing of a plantar forefoot ulcer, and there are no uniform definitions of recurrent and other new ulcers. The aim of this study was to evaluate the outcome of a large cohort of consecutively treated patients with diabetes mellitus and a healed planter forefoot ulcer (n=617) with regard to development, characteristics, and outcome of recurrent and other new ulcers. Patients were followed consecutively and prospectively with a two-year follow-up, according to a pre-set protocol. Out of 617 patients, 250 (41%) did not develop any new ulcer, 262 (42%) developed a new ulcer, 87 (14%) died and 18 (3%) were lost at two years following healing of a plantar forefoot ulcer. Thirty-four per cent developed other new ulcers (112 on the same foot and 99 on the contralateral foot), whereas 51 patients (8%) developed a recurrent ulcer (at the same site and foot). Of the patients who died within two years, 30 patients had developed other new ulcers. The risk of a recurrent ulcer in patients with diabetes and a healed plantar forefoot ulcer was only eight per cent within two years, whereas other new ulcers, on the same foot or on the contralateral foot, was seen in 4 out of 10 patients indicating the need for further preventive measures and surveillance in these patients. We suggest a concise definition for new ulcer to be used in future research. This article is protected by copyright. All rights reserved.

  4. Tri-potassium di-citrato bismuthate: a report of its pharmacological properties and therapeutic efficacy in peptic ulcer.

    1976-12-01

    Tri-potassium di-citrato bismuthate is a complex bismuth salt stable in colloidal form advocated for the treatment of peptic ulcer. Preliminary placebo-controlled trials in small numbers of ambulant patients with endoscopically proven peptic ulcer, strongly suggest that the compound accelerates the rate of healing of gastric and duodenal ulcer within 4 weeks of treatment. However, trials involving larger numbers of patients followed-up for longer periods are required before a clear verdict on the efficacy of tripotassium di-citrato bismuthate in gastric and duodenal ulcer can be given. There are no reliable data on the effect of the drug on ulcer recurrence rate. Side-effects are negligible and the drug could become an important therapeutic agent in peptic ulcer therapy if results of further study are conclusive. The drug causes dark discolouration of the stools and this should be borne in mind when considering the possibility of the presence of intestinal bleeding.

    The objective of this article was to study characteristics of pressure ulcer patients and their ulcers, pressure ulcer preventive and treatment measures in four Indonesian general hospitals. A multicentre cross-sectional design was applied to assess pressure ulcers and pressure ulcer care in adult patients in medical, surgical, specialised and intensive care units. Ninety-one of the 1132 patients had a total of 142 ulcers. Half (44·0%) already had pressure ulcers before admission. The overall prevalence of category I-IV pressure ulcers was 8·0% (95% CI 6·4-9·6), and the overall nosocomial pressure ulcer prevalence was 4·5% (95% CI 3·3-5·7). Most pressure ulcer patients had friction and shear problems, were bedfast, had diabetes and had more bedridden days. Most ulcers (42·3%) were category III and IV. One third of the patients had both pressure ulcers and moisture lesions (36·3%) and suffered from pain (45·1%). The most frequently used prevention measures were repositioning (61·5%), skin moisturising (47·3%), patient education (36·3%) and massage (35·2%). Most pressure ulcer dressings involved saline-impregnated or antimicrobial gauzes. This study shows the complexities of pressure ulcers in Indonesian general hospitals and reveals that the quality of pressure ulcer care (prevention and treatment) could be improved by implementing the recent evidence-based international guideline.

    Landing and squat tasks have been utilized to assess lower extremity biomechanics associated with anterior cruciate ligament loading and injury risks. The purpose of this study was to identify the differences and correlations in knee and hip mechanics during a single-leg landing, a single-leg squat, a double-leg landing, and a double-leg squat. Seventeen male and 17 female recreational athletes performed landings and squats when kinematic and kinetic data were collected. ANOVAs showed significant differences (p < 0.00001) for maximum knee flexion angles, maximum hip flexion angles, maximum knee abduction angles, maximum hip adduction angles, and maximum external knee abduction moments among squats and landings. For maximum knee and hip flexion angles, significant correlations (r ≥ 0.5, p ≤ 0.003) were observed between the two landings and between the two squats. For maximum knee abduction and hip adduction angles and maximum external knee abduction moments, significant correlations were mostly found between the two landings, and between the single-leg squat and landings (r ≥ 0.54, p ≤ 0.001). Individuals are likely to demonstrate different profiles of injury risks when screened using different tasks. While a double-leg landing should be considered as a priority in screening, a single-leg squat may be used as a surrogate to assess frontal plane motion and loading.

    In a proposed alternative to previous approaches to making hot-shoe contacts to the legs of thermoelectric devices, one relies on differential thermal expansion to increase contact pressures for the purpose of reducing the electrical resistances of contacts as temperatures increase. The proposed approach is particularly applicable to thermoelectric devices containing p-type (positive-charge-carrier) legs made of a Zintl compound (specifically, Yb14MnSb11) and n-type (negative charge-carrier) legs made of SiGe. This combination of thermoelectric materials has been selected for further development, primarily on the basis of projected thermoelectric performance. However, it is problematic to integrate, into a practical thermoelectric device, legs made of these materials along with a metal or semiconductor hot shoe that is required to be in thermal and electrical contact with the legs. This is partly because of the thermal-expansion mismatch of these materials: The coefficient of thermal expansion (CTE) of SiGe is 4.5 x 10(exp -6) C (exp -1), while the CTE of Yb14MnSb11 is 20 x 10(exp -6) C(exp -1). Simply joining a Yb14MnSb11 and a SiGe leg to a common hot shoe could be expected to result in significant thermal stresses in either or both legs during operation. Heretofore, such thermal stresses have been regarded as disadvantageous. In the proposed approach, stresses resulting from the CTE mismatch would be turned to advantage.

    A great deal of emphasis, clinical and financial, is placed on limb salvage efforts in diabetic patients suffering from lower extremity ulceration. This is because of the impression that amputation in such patients may be a proximal cause of death. While amputation is certainly a negative clinical outcome, it is not entirely clear that it causes death. In this systematic review, we examine the available literature to attempt to understand the role that the ulceration itself may play in mortality. In brief, we searched for human studies in OVID, CINAHL and the COCHRANE CENTRAL DATABASE from 1980 to 2013, looking for articles related to ulcer or wound of the foot, in patients with diabetes or peripheral vascular disease, and death. We looked for articles with 5 years of follow-up, or Kaplan-Meier estimates of 5-year mortality, and excluded reviews and letters. Articles were assessed for quality and potential bias using the Newcastle-Ottawa scale. We find that while the patient populations studied varied widely in terms of demographics and comorbidities, limiting generalisability, 5-year mortality rates after ulceration were around 40%. Risk factors for death commonly identified were increased age, male gender, peripheral vascular disease and renal disease.

    This article reports on the introduction of an innovative computer-based system developed to record and report pressure ulcer risk and incidence at an acute NHS trust. The system was introduced to ensure that all patients have an early pressure ulcer risk assessment, which prompts staff to initiate appropriate management if a pressure ulcer is detected, thereby preventing further patient harm. Initial findings suggest that this electronic process has helped to improve the timeliness and accuracy of data on pressure ulcer risk and incidence. In addition, it has resulted in a reduced number of reported hospital-acquired pressure ulcers.

  11. Hot Leg Piping Materials Issues

    With Naval Reactors (NR) approval of the Naval Reactors Prime Contractor Team (NRPCT) recommendation to develop a gas cooled reactor directly coupled to a Brayton power conversion system as the space nuclear power plant (SNPP) for Project Prometheus (References a and b) the reactor outlet piping was recognized to require a design that utilizes internal insulation (Reference c). The initial pipe design suggested ceramic fiber blanket as the insulation material based on requirements associated with service temperature capability within the expected range, very low thermal conductivity, and low density. Nevertheless, it was not considered to be well suited for internal insulation use because its very high surface area and proclivity for holding adsorbed gases, especially water, would make outgassing a source of contaminant gases in the He-Xe working fluid. Additionally, ceramic fiber blanket insulating materials become very friable after relatively short service periods at working temperatures and small pieces of fiber could be dislodged and contaminate the system. Consequently, alternative insulation materials were sought that would have comparable thermal properties and density but superior structural integrity and greatly reduced outgassing. This letter provides technical information regarding insulation and materials issues for the Hot Leg Piping preconceptual design developed for the Project Prometheus space nuclear power plant (SNPP).

    Restless legs syndrome (RLS) is a common sensorimotor neurological disorder that is diagnosed according to the revised criteria of the International RLS Study Group (IRLSSG). The pathophysiology of RLS is still unknown and its prevalence is influenced by ethnicity, age, and gender. RLS is divided into two types by etiology: primary or idiopathic and secondary. Primary RLS is strongly influenced by a genetic component while secondary RLS is caused by other associated conditions such as end-stage renal disease or peripheral neuropathy. Another common condition associated with RLS is pregnancy. The prevalence of RLS during pregnancy is two to three times higher than in the normal population and is influenced by the trimester and the number of parity. The main mechanisms that may contribute to the pathophysiology of RLS during pregnancy are hormonal changes and iron and folate status. Standard medications for treating RLS during pregnancy are not established. Most medications have been used according to the evidence from non-pregnant patients. Therefore, consideration of the medical treatment for treating RLS during pregnancy should be balanced between the benefit of relieving the symptoms and maternal and fetal risk. In general, the prognosis of RLS during pregnancy is good and symptoms are usually relieved after delivery. PMID:24768121

    The mechanism of development of experimental gastric ulcers, induced in rats by combined immobilization and electric shock, was analyzed pharmacologically with peripheral neurotropic agents. It is concluded that: (1) The most marked preventive effect in the development of the experimentally induced gastric ulcers was displayed by agents capable of blocking the ascending activation system of the reticular formation. (2) Sympathetic fibers, which disrupt the trophism of the gastric wall, form the efferent portion of the reflex arc. (3) Gastric secretion does not appear to be the primary cause of ulceration.

    Herpes simplex virus (HSV) ocular infection causes significant visual burden worldwide. Despite the fact that dendritic or geographic corneal ulcers are typical findings in HSV epithelial keratitis, conjunctival ulcer as a sign of HSV infection has rarely been reported. Although easily overlooked, this important sign could be enhanced by fluorescein staining. We report two cases of conjunctival geographic ulcers proven to be HSV infection by viral isolation and polymerase chain reaction (PCR). One patient had bilateral disease and blepharitis, and the other had unilateral involvement without skin lesions. With timely diagnosis and proper management, excellent visual outcome can be expected.

    The authors tried to verify the efficacy of Low Power Laser (LPL) in scalp alopecia and crural ulcers of different causes. Laser used was (red diode, continuous emission, 8 mW power, wave length 670 nm spot size about 5 mm diameter on some points 1 - 2 minutes per point. We also use as control classical therapy. Before, during and after treatment, histological samples were done for alopecia. For laser groups (alopecia and ulcers) the results were rather superior and in a three or twice time shorter than control group. We conclude that LPL therapy is a very useful complementary method for the treatment of scalp alopecia and crural ulcers.

    Restless legs syndrome (RLS) is an extremely distressing problem experienced by patients on dialysis; the prevalence appears to be greater than in the general population, with a wide variation from 6.6% to 80%. The diagnosis of RLS is a clinical one, and its definition has been clarified and standardized by internationally recognized diagnostic criteria, published in 1995 by the International Restless Legs Syndrome Study Group (IRLSSG). This study was designed to find out the prevalence of RLS in Saudi patients with end-stage renal disease (ESRD) on maintenance dialysis. This is a cross sectional study carried out between May and Sept 2007 at two centers, King Abdulaziz Medical City-King Fahad National Guard Hospital (KAMC-KFNGH), Riyadh and King Faisal Specialist Hospital and Research Centre (KFHRC), Jeddah, Saudi Arabia. Data were gathered on 227 Saudi patients on chronic maintenance hemodialysis or chronic peritoneal dialysis. The prevalence of RLS was measured using IRLSSG's RLS Questionnaire (RLSQ). Potential risk factors for RLS including other sleep disorders, underlying cause of chronic renal failure, duration on dialysis, dialysis shift, biochemical tests and demographic data were also evaluated. The overall prevalence of RLS was 50.22% including 53.7% males and 46.3% females. Their mean age was 55.7 +/- 17.2 years and mean duration on dialysis 40.4 +/- 37.8 months. Significant predictors of RLS were history of diabetes mellitus (DM), coffee intake, afternoon dialysis, gender and type of dialysis (P= 0.03, 0.01, < 0.001, 0.05 and 0.009 respectively). Patients with RLS were found to be at increased risk of having insomnia and excessive daytime sleepiness (EDS) (P= < 0.001 and 0.001, respectively). Our study suggests that RLS is a very common problem in dialysis population and was significantly associated with other sleep disorders, particularly insomnia, and EDS. Optimal care of dialysis patient should include particular attention to the diagnosis and

    Leg ulcers are a major complication of sickle cell disease that occur in 2.5-40% of patients. Leg ulcers are responsible for frequent complications because they are often long-lasting and are highly resistant to therapy. Although their occurrence is associated with hyperhemolysis, the mechanisms underlying sickle cell ulcers remain poorly understood. In this study, we show that skin wound healing is severely altered in old SAD sickle cell mice but is normal in young animals, consistent with reports in humans. Alterations of wound healing were associated with impaired blood and lymphatic angiogenesis in the wound beds and poor endothelial progenitor cell mobilization from the bone marrow. CXCL12 secretion by keratinocytes and inflammatory cells was low in the wounds of SAD mice. Local therapy with endothelial progenitor cells or recombinant CXCL12 injections restored wound angiogenesis and rescued the healing defect together with mobilization of circulating endothelial progenitor cells. To our knowledge, this is a previously unreported study of the cellular and molecular mechanisms of sickle cell ulcers in a murine model that provides promising therapeutic perspectives for clinical trials.
