CHLD score, a new score based on traditional risk factor evaluation and long-term cardiovascular outcomes in patients with systemic sclerosis.

The aim of the study was to assess the predictors of major adverse cardiovascular events (MACE) in patients with systemic sclerosis (SSc) without pulmonary arterial hypertension. The study comprised 68 patients with SSc who were followed up for the median time of 99 (96; 107) months. The main exclusion criteria involved tricuspid regurgitation maximal velocity > 2.8 m/s and structural heart disease. At baseline the patients underwent clinical assessment of cardiovascular risk factors, 6-min walk test, transthoracic echocardiography and biomarker testing, including growth differentiation factor 15 (GDF-15). The primary composite endpoint was onset of MACE defined as death, myocardial infarction, myocardial revascularization and hospitalization for heart failure. The follow-up consisted of outpatient visits at 1 year intervals and telephone interview every 6 months. The baseline analysis revealed that chronic kidney disease (HR 28.13, 95%CI 4.84-163.38), lung fibrosis on high resolution computed tomography (HR 4.36, 95%CI 1.04-18.26) and GDF-15 concentration (unit HR 1.0006, 95%CI 1.0002-1.0010) were independent predictors of MACE occurrence. CHLD (Chronic kidney disease, Hypertension, hyperLipidaemia, Diabetes mellitus) score was formulated which assigned 1 point for the presence of arterial hypertension, hyperlipidaemia, diabetes mellitus and chronic kidney disease. After inclusion of CHLD score in Cox proportional model, it remained the only independent predictor of MACE onset (unit HR per 1 point 3.46; 95%CI 2.06-5.82, p < 0.0001). Joint assessment of traditional risk factors in the form of CHLD score may serve as a reliable predictor of long-term outcome in patients with SSc without pulmonary arterial hypertension.

Assessment of the anxiety and depression among patients with idiopathic pruritus ani.

INTRODUCTION: Pruritus ani is an unpleasant sensation that leads to scratching of the skin around the anus. It is a common symptom due to many systemic, dermatological, and proctological conditions. In the absence of evident organic origin of a disease, pruritus may be related to mental disorders as well as personality disorders. AIM: To assess the influence of pruritus on anxiety and depression in these patients. MATERIAL AND METHODS: The study involved 60 patients complaining of persistent pruritus ani. The study included people in which pruritus for organic reasons was ruled out. Tests were carried out to assess the level of depression and anxiety disorders. In addition, patients were asked to fill in the Questionnaire for the Descriptive Assessment of Pruritus and the 4-Item Itch Questionnaire by prof. Jacek Szepietowski. RESULTS: The cause of pruritus ani in the study groups has been shown to have a significant influence on the level of depressive symptoms. There was no such relationship for anxiety disorders. In the study group, there was no correlation of depressive-anxiety symptoms with the level of pruritus intensity and the frequency of pruritus. CONCLUSIONS: The presented data reveal the negative effect of pruritus ani on the psychological functioning of patients. Pruritus ani is characterized by moderate intensity of pruritus, but has a significant influence on the aggravation of depressive symptoms. It is important to look for the causes of this symptom, which can help to eliminate its intensity, improve the patients' mood, and thus improve their quality of life.

Extensive Cutaneous Ulceration of the Scalp - Unknown Disease Entity or Dermatitis Artefacta?

Psychological disturbances and emotional stress events may elicit a wide spectrum of skin disturbances which are classified as dermatitis artefacta. This diagnosis should be taken into consideration when symptoms coexist in a bizarre pattern or indicate at least several distinct skin pathologies while laboratory tests remain inconclusive. We present a case of dermatitis artefacta which produced very extensive loss of the scalp. Our intention was to show difficulties in diagnostic management of this recurrent and complex psychiatric disorder which may inconvenience clinicians. Neither laboratory tests (including bacteriology) nor X-ray of the skull identified any significant pathology. Although histopathology excluded skin malignancy, it showed an unspecific pattern not attributable to the most probable skin conditions like pyoderma gangrenosum or infection. Psychiatric consultation was inconclusive. Despite undetermined diagnosis, the patient was eligible for reconstructive surgery, which restored his scalp coverage. Different skin conditions may share very similar spectra of clinical symptoms, and even deep medical investigation does not always enable us to define the observed condition. However, both laboratory and imaging tests are necessary to exclude infections or potential malignancies before the diagnosis of dermatitis artefacta is established, whereas psychiatric consultation may or may not identify mental issues.

Correlation between the infrared thermogram and microvascular abnormalities of the nailfold in patients with systemic sclerosis.

INTRODUCTION: Systemic sclerosis (SSc) is a multisystemic disease with an extensive microvasculopathy. The gold standard for its investigation is nailfold videocapillaroscopy (NVC). AIM: To assess the value of thermography (IRT) for the assessment of microvasculopathy in patients with SSc. MATERIAL AND METHODS: Nineteen patients with limited cutaneous SSc were enrolled in the study. They underwent IRT imaging and NVC. An average temperature (Tavg) at the nailfold and a gradient of temperatures (ΔTavg) between the central metacarpus of the hand and the nailfold was determined for all fingers. NVC pictures were classified to capillaroscopic patterns according to Cutolo et al. system and they were analysed quantitatively to measure the density of capillaries and to calculate capillaroscopic skin ulcers risk index (CSURI) for each finger separately. RESULTS: There was only a moderate correlation (0.4 < r < 0.6) between thermographic parameters and density of capillaries in fingers II-V (r = 0.5; p < 0.001 for Tavg and r = -0.45; p < 0.001 for ΔTavg), but none in thumbs (r = 0.29; p = 0.089 for Tavg and r = -0.19; p = 0.275 for ΔTavg). Early pattern was associated with a significantly greater surface temperature (Tavg) of nailfolds and essentially milder ΔTavg in fingers II-V when compared to all other capillaroscopic patterns in fingers II-V. Surface temperature (Tavg) was significantly lower and ΔTavg was markedly more pronounced in fingers II-V with a greater risk of development of digital ulcers (DU) calculated by CSURI. CONCLUSIONS: Although IRT measurements correlate only moderately with density of capillaries, this technique seems to be substantial to determine the capillaroscopic pattern and to identify patients at greater risk of DU development.

The efficacy of antimalarial drugs in the therapy of selected forms of cicatricial alopecia.

INTRODUCTION: Frontal fibrosing alopecia (FFA) is primary lymphocytic cicatricial alopecia with a clinically characteristic progressive recession of the frontotemporal hairline, perifollicular erythema, as well as symptoms of itching and burning. It occurs mainly in postmenopausal women. FFA is considered as a subtype of lichen planopilaris (LPP). The treatment of those diseases is presently empirical. AIM: To define the efficacy of treating FFA and LPP with hydroxychloroquine. MATERIAL AND METHODS: We performed a retrospective analysis of 95 women, including 35 with FFA and 60 with LPP. We collected the relevant demographic and clinical data. The response to treatment with hydroxychloroquine was assessed using LPPAI. Also, adverse events were monitored. RESULTS: Treatment with hydroxychloroquine has a statistically significant effect on decreasing the disease activity after 6 and 12 months of therapy. The results of statistical tests do not confirm the existence of a relationship between age range and treatment efficacy. However, there is a correlation between the duration and efficacy of treatment (p < 0.05). CONCLUSIONS: Administration of hydroxychloroquine can be considered as one of the treatment methods for FFA and LPP in everyday clinical practice. The presented study is the first attempt at using hydroxychloroquine to treat such large patient groups for FFA and LPP. Hydroxychloroquine efficaciously alleviates the symptoms in LPP patients and gives maximum benefits in long-term therapy (12 months). The preliminary results obtained in the presented retrospective analysis should be confirmed in a randomized prospective clinical trial, which remains a future challenge for researchers.

Frontal fibrosing alopecia: a disease that remains enigmatic.

Frontal fibrosing alopecia (FFA) is recognized to represent a generalized process of inflammatory scarring alopecia. Apart from the classic form affecting the frontal hairline, there are a range of disease manifestations involving loss of eyebrows and of eyelashes, loss of peripheral body hair, fibrosing alopecia in a pattern distribution, facial and extrafacial skin, mucous membrane, and nail involvement. Classic linear, diffuse "zigzag", pseudo "fringe sign", androgenetic alopecia-like, cockade-like, ophiasis-like and incomplete patterns are distinguished. The aetiology of FFA remains obscure, but a number of pathogenetic hypotheses and treatments to halt disease progression have been proposed.

Factors affecting the concentration of soluble tumour necrosis factor-α receptor type I in the blood serum of patients with localized scleroderma.

AIM: The aim of the study was to assess of sTNFαR1 concentration in the serum of patients with localized scleroderma (in comparison with a control group). MATERIAL AND METHODS: This was a prospective study. The patients with localized scleroderma were divided into two groups: 21 persons treated with PUVA therapy and 20 persons treated with procaine penicillin. In the case of the patients treated with intramuscularly administered procaine penicillin (dose: 2,400,000 IU/day), achievement of a total dose of at least 30 million IU/day was considered as the end of the therapy. In the group of patients treated with photochemotherapy, the single initial dose during a PUVA session was 0.5 J/cm2 and it was increased by 0.5 J/cm2 every other day to reach the maximum value of 10 J/cm2, depending on the clinical condition. The study involved three sessions a week. RESULTS: sTNFαR1 concentration in the serum of patients with localized scleroderma was significantly higher in comparison with the control group and correlated with the skin damage index. The difference in the determined particle level was higher in the group of patients undergoing photochemotherapy (median: 106.25 ng/ml) than in the group taking penicillin (median: 81.50 ng/ml). Patients treated with PUVA sessions demonstrated a greater decrease in sTNFαR1 concentration and an improvement of the clinical condition after therapy completion. CONCLUSIONS: The obtained results suggest a potential role of sTNFαR1 in the pathogenesis of localized scleroderma.

Features of dermatofibroma in reflectance confocal microscopy.

BACKGROUND: Dermatofibroma (DF) is a common benign skin lesion in a majority of cases located on the legs or upper limbs. The etiology of DF is still unclear. OBJECTIVES: Reflectance confocal microscopy features of DF were described. METHODS: Forty patients with DF diagnosis confirmed by dermoscopy were examined using reflectance confocal microscopy VivaScope 1500 from March 2018 to April 2019. RESULTS: DF was more common in females (80%) than males (20%). Thirty-six lesions (90%) were located on the limbs while four (10%) were on the trunk. Dermoscopically, 18 lesions (45%) revealed typical features: central white area with a brown network in the periphery. Twenty-two DFs (55%) were found with a central white patch and globular-like structures, surrounded by a thin brown network. In reflectance confocal microscopy, all revealed a typical honeycombed pattern, although in some cases (30%), streaming was observed. In two lesions (5%) in epidermis, few dendritic cells were observed, and one DF revealed roundish pagetoid cells (2.5%). The dermoepidermal junction (DEJ) in all lesions was abounded in dilated vessels. The most common observable feature of DF was bright "rings" composed of monomorphic, regular cells surrounding dark dermal papillae. In five lesions (12.5%), rings were "double" because of exceptionally pigmented DF. CONCLUSION: Reflectance confocal microscopy enables us to describe microscopic features of DF. There are four confocal microscopic features observable in each DF: in the epidermis, normal honeycombed pattern, sometimes with local streaming, in DEJ, edged papillae, bright rings, and dilated vessels.

Does adiponectin play a role in the pathogenesis of chronic spontaneous urticaria?

INTRODUCTION: Chronic spontaneous urticaria constitutes an interdisciplinary problem and its pathogenesis is still a subject of debate. Overweight and hyperlipidemia are supposed to be related to chronic spontaneous urticaria. Fatty tissue can be the source of adipokines. AIM OF THE STUDY: To assess the potential role of adiponectin in chronic spontaneous urticaria pathogenesis. MATERIAL AND METHODS: The study included 52 chronic spontaneous urticaria patients and 43 healthy controls. The patients were divided into two subgroups: patients with wheals only, and patients with urticaria and an accompanying angioedema. The adiponectin concentration was measured in all studied subjects. RESULTS: No statistically significant difference in adiponectin level was determined between the studied groups and subgroups. CONCLUSIONS: We are among the first to present the results of study to determine a possible role of adipokines in chronic spontaneous urticaria pathogenesis. We did not observe any difference in adiponectin level. In our opinion, it is necessary to conduct further analyses in this field.

Health-related quality of life and its influencing factors in adult patients with localized scleroderma - a cross-sectional study.

BACKGROUND: Localized Scleroderma (LoS) is an autoimmune connective tissue disease that affects skin and less commonly subcutaneous tissues. The illness occurs in children and adults, and may have a serious impact on health-related quality of life (HRQoL). The goal of this study was to explore what factors might deteriorate scores on HRQoL measures in adult LoS patients. METHODS: Detailed information on the demographic and clinical features of LoS patients was collected. The HRQoL was assessed using Skindex-29 and Short form 36 (SF-36) questionnaires. RESULTS: Thirty three women and seven men with LoS were enrolled. Female gender negatively influenced scores for the emotion subscale of Skindex-29. Multiple-factor linear regression analysis confirmed, as with single-factor analysis, that the causes of low SF-36 physical component score (PCS) were subjective symptoms (pruritus, pain, paresthesia), musculoskeletal manifestations and older age at the time of survey, while rural area of residence negatively affected the SF-36 mental component score. Additionally, single-factor analysis showed that the SF-36 PCS was related to the LoS cutaneous assessment tool (LoSCAT) summary score. CONCLUSIONS: Apart from a clinical presentations, sociodemographic characteristics, including older age, female gender and living conditions, may impair HRQoL of LoS patients. Further studies that will examine the role of these factors for physical and mental functioning of adults with LoS are needed.

Associations between Disease Activity/Severity and Damage and Health-Related Quality of Life in Adult Patients with Localized Scleroderma-A Comparison of LoSCAT and Visual Analogue Scales.

Localized scleroderma (LoS) is a chronic fibrosing disorder of the skin and, less commonly, subcutaneous tissues. As the disease causes subjective symptoms, cosmetic defects, and, at times, functional disability, subjects with LoS experience deterioration of their health-related quality of life (HRQoL). The influence of disease activity/severity and damage status on HRQoL measures in patients with LoS is scarcely known. Physician-reported measures (modified LoS skin severity index, LoS skin damage index, physician global assessments of the disease activity/severity and damage) and patient-derived measures (patient global assessments of the disease activity/severity and damage) were obtained in adult LoS patients. Their HRQoL was measured with Skindex-29 and Short Form-36. The patients' assessments of disease activity/severity and damage in LoS differed from the assessments by the physicians. The patients' predominant concerns centered on LoS-related damage, whereas the physicians' concerns focused on features of disease activity. Visual analogue scales bore some relation to the HRQoL, and they seem to be important in a holistic approach to the patient and should not be omitted in LoS evaluation.

MORPHEA AND LICHEN SCLEROSUS IN A PATIENT WITH HYPORTHYROIDISM.

Thyroid gland is one of the key organs regulating the metabolism of carbohydrates, proteins and fats. Its primary function is connected with increase of the metabolic conversion of the body. Skin lesions are often one of the first symptoms of hypothyroidism. In a 71-year-old patient, skin lesions in the form of thickened areas with severe hyperkeratosis first appeared 12 years before. Eight years before, the patient was diagnosed with hypothyroidism of unknown cause. Upon admission, lesions were observed in the trunk area, left arm and vulva. These lesions had the appearance of brownish spots with hyperkeratosis. Initially, they were localized on the trunk, then involving upper limbs and neck area with time. Significant progression was present in the back area. In the anogenital area, porcelain-white discolorations were observed. Laboratory examinations were normal. During hospital stay, iv. ceftriaxone at a dose of 2.0 g/day for 10 days and intramuscular injection of vitamin B6 were administered, along with 10% urea ointment for hyperkeratosis lesions as topical therapy. The patient had lesions in the form of skin induration and discoloration, with visible, very severe hyperkeratosis, which is not characteristic of changes of the scleroderma and lichen sclerosus type. These lesions caused diagnostic problems due to the atypical clinical appearance.

Evaluation of PSEN1 subunit of the γ-secretase gene in patients with psoriasis vulgaris: a pilot study.

INTRODUCTION: Psoriasis is a chronic autoimmune inflammatory disease, the prevalence of which is 1-3% in the Polish population. Genome testing using single nucleotide polymorphisms revealed more than 50 regions associated with the risk of psoriasis, and most of these genes are associated with the immune system. AIM: To assess the presence of PSEN1 subunits of the γ-secretase gene polymorphisms in patients with psoriasis and comparison of results with a healthy control group. MATERIAL AND METHODS: We used polymerase chain reaction - restriction fragment length polymorphism (PCR RFLP) method to assess polymorphisms. The starting material for analysis was peripheral blood obtained from the patient. RESULTS: PSEN1a-positivity was found in 2/52 (2.78%) of patients with psoriasis and 1/36 (3.85%) of healthy controls. PSEN1b positivity was seen in 3/52 (5.77%) of patients with psoriasis and 1/36 (3.85%) of control individuals. Only 3 patients with psoriasis but none of healthy volunteers had a presence of PSEN1c. Four patients were excluded from further statistical analysis. CONCLUSIONS: We have not shown a relationship between PSEN1 polymorphism and the clinical occurrence of psoriasis but now we start the assessment of other subunits of the γ-secretase gene - PSENEN and NCSTN.

What is the Best Way to Treat Patients with Raynaud's Phenomenon and a Tendency towards Hypotension?

Episodes of excessive vasospasm are common in patients with Raynaud's phenomenon (RP). Pharmacological treatment may often result in side-effects such as hypotension, leading to discontinuation of treatment. Review of therapeutic interventions with regard to tendency towards hypotension was done in medical databases including PubMed, Scopus, and Medline to summarize the current state of the knowledge. Despite the episodes of blood pressure drops caused by hypotension, calcium channel blockers (CCB) have been widely used in RP as first-line treatment medication. The use of other CCB apart from nifedipine is controversial due to the variety of results in clinical trials. A clinical study comparing the efficacy and tolerability of losartan with nifedipine revealed a significant reduction in RP severity, frequency of episodes, and reported adverse effects. Application of oral sildenafil 100 mg/d as an add-on therapy increased microvascular blood flow in secondary RP, while being well-tolerated and with no withdrawal from the study. Topical vasodilators may be applied as an adjuvant therapy for patients with RP. Clinical studies approved 10% nifedipine cream and 10% nitroglycerine gel as an efficient RP therapy with side-effects comparable with placebo usage. Non-pharmacological interventions, such as cold avoidance, stress management, and smoking cessation are recommended in reducing episodes of RP. Calcium channel blockers, with a particular emphasis on nifedipine, in combination with non-pharmacological management seem to be the optimal way to treat the patients with a tendency to hypotension.

Are new variants of psoriasis therapy (IL-17 inhibitors) safe?

Psoriasis is a chronic, recurrent, inflammatory, and proliferative skin disease. Its etiology has not yet been fully assessed, but undoubtedly it is a multifaceted disease. The key role in its pathomechanism is played by genetic, immunologic, and environmental factors and stress. If traditional methods of psoriasis treatment (phototherapy, methotrexate, retinoids, cyclosporine A) fail, we reach for the following biopharmaceuticals - infliximab, etanercept, adalimumab, or ustekinumab. However, genetic engineering progress discovers new possibilities - the pending clinical trials involve IL-17, IL-23 antagonists, PDE4 and -3 and -1. Psoriasis etiopathogenesis mainly involves the IL-17A, IL-17F, and IL-17A/F subtypes, which affect the keratinocytes. The biological therapy molecularly oriented with the antagonists of interleukin 17 is based mainly on the influence onto the cytokine in the manner that prevents it from binding with the receptor. Three biopharmaceuticals are currently under third phase studies: two fully humanized antibodies neutralizing IL-17 - ixekizumab and secukinumab, and one human monoclonal antibody, brodalumab. The below work will be devoted to the analysis of possible undesirable symptoms, which were observed during the studies. We will try to review the latest literature concerning the most important clinical trials conducted in many centers.

The safety of isotretinoin treatment in patients with bone fractures.

Isotretinoin is widely applicable in dermatology, although it may develop severe side effects in the skeletal system. An intention of this review was to establish the safety of oral isotretinoin in patients with bone fractures. Both MEDLINE/Pubmed and SCOPUS databases were searched to investigate the influence of isotretinoin on the skeletal system. The drug shows a strong osteoporotic activity in rats whereas this effect is milder in humans. Biochemical markers of bone turnover remain unchanged except for serum calcium in patients receiving a high dose of isotretinoin. An excessive intake of vitamin A may impair functioning of vitamin D especially in people with a vitamin D deficiency, therefore a similar side effect may also occur in patients on isotretinoin treatment. We suggest reducing the use of isotretinoin after bone injury or continuing the treatment at low dosing with a concomitant correction of vitamin D and calcium status.

An extended high-frequency ultrasound protocol for assessing and quantifying of inflammation and fibrosis in localized scleroderma.

BACKGROUND: Clinical characteristics of the lesions are used to identify activity and damage in localized scleroderma (LoS). For high-frequency ultrasound (HF-US), the features of active lesions were described. MATERIALS AND METHODS: Clinical signs of activity and damage in LoS lesions were assessed with the use of Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) and HF-US by two examiners independently. All US images were obtained using a 20 MHz HF-US (DermaLab System, Cortex Technology, Hadsund, Denmark). The dermal thickness (DT) and echogenicity (intensity score, IS) of the LoS lesional dermis were measured in the area of each lesion with the highest score for erythema (ER), skin thickness (ST), and dermal atrophy (DAT). Measurements were compared to the site-matched unaffected skin. The relative difference of DT and IS values was calculated between each lesion and its normal control for comparison among different clinical scores for ER, ST, and DAT. RESULTS: A total of 92 lesions in 40 adult patients were examined with HF-US. Thirty one lesions were erythematous, 26 were in sclerosis, and 35 were in atrophy. A correlation between the clinical evaluation of the LoS lesions and US measurements was found. The sensitivity and specificity of HF-US were 97% and 90%, respectively. The positive predictive value was 83%, negative predictive value-98%. Interrater reliability was excellent for LoSCAT and HF-US findings. CONCLUSION: High-frequency ultrasound allows an accurate assessment of the inflammatory and fibrotic skin lesions in LoS.

Clinical and molecular evaluation of therapy with the use of cyclosporine A in patients with psoriasis vulgaris.

BACKGROUND: Psoriasis course involves increased secretion of pro-inflammatory cytokines, among others, a beta transforming growth factor (TGFßs) and its receptors. Cyclosporine A (CsA), an immunosuppressive medicine with the molecular mechanism of operation connected with the properties of cell cycle suppression, is often used in the treatment of severe forms of psoriasis. The efficacy of therapy is assessed based on the disease clinical progression indexes - Psoriasis Area and Severity Index (PASI), body surface area (BSA), and Dermatology Life Quality Index (DLQI). The aim of the study was the evaluation of the efficacy of the CsA treatment of patients with psoriasis vulgaris, based on the clinical parameters and an assessment of the expression profiles of TGFßs and TGFßRs, depending on the concurrent diabetes and metabolic syndrome. METHODS: The group under study composed of 32 patients (15 with the metabolic syndrome, seven with diabetes) treated with CsA for 84 days. The molecular analysis included extraction of RNA, assessment of TGßF1-3, TGFßRI-III gene expression with the use of the RTqPCR method. The clinical assessment of the effects of this pharmacotherapy involved evaluation of the parameters: PASI, BSA, DLQI before therapy commencement, on the 42nd and 84th days of therapy. RESULTS: A statistically significant change in the transcription activity of TGFß1 in patients with and without diabetes (P = 0.018) and patients with and without metabolic syndrome (P = 0.023) was shown that on the 84th day of therapy. CONCLUSIONS: TGFb1 may be claimed as the supplementary molecular marker to evaluate the efficacy of CsA therapy. It seems that systemic diseases have an effect on the efficacy of the applied pharmacotherapy and the course of psoriasis.

Comparison of ultrasound therapy and radial shock wave therapy in the treatment of venous leg ulcers - clinical, pilot study.

INTRODUCTION: Venous insufficiency and venous leg ulcers each year affect more and more people, especially in developed countries. The challenge of our time is to find an effective method of treating venous leg ulcers, which will further shorten treatment time and reduce the cost of treatment. AIM: To compare the effects of treating venous leg ulcers using ultrasound therapy, radial shock wave therapy and standard care. MATERIAL AND METHODS: Group A consisted of 17 patients. Patients were treated with ultrasound therapy US power density 0.5 W/cm2, pulsed wave with a duty cycle of 1/5, and 1 MHz frequency. Group B consisted of 17 patients. Patients were treated with the radial shock wave R-ESWT using surface energy density 0.17 mJ/mm2, 100 impulses/cm2, frequency of 5 Hz and a pressure of 0.2 MPa. Group C (control group) consisted of 17 patients. Patients in this group received standard care: gauze dressing saturated in 0.9% sodium chloride and elastic bandages changed daily for 4 weeks. RESULTS: Ultrasound therapy with 1 MHz and energy power density 0.5 W/cm2 for 4 weeks resulted in an average reduction of 68% of the area of ulceration. We used for venous leg ulcers 4-week treatment with radial shock wave therapy resulting in a 38% mean percentage reduction of the ulceration area. Standard care reduces the area of ulceration by only 16%. CONCLUSIONS: The use of ultrasound therapy for the treatment of venous leg ulcers is more effective than the use of radial shock wave therapy or standard care alone.
