Consensus on the diagnosis and management of chronic leg ulcers - Brazilian Society of Dermatology.

BACKGROUND: Chronic leg ulcers affect a large portion of the adult population and cause a significant social and economic impact, related to outpatient and hospital care, absence from work, social security expenses, and reduced quality of life. The correct diagnosis and therapeutic approach are essential for a favorable evolution. OBJECTIVE: To gather the experience of Brazilian dermatologists, reviewing the specialized literature to prepare recommendations for the diagnosis and treatment of the main types of chronic leg ulcers. METHODS: Seven specialists from six university centers with experience in chronic leg ulcers were appointed by the Brazilian Society of Dermatology to reach a consensus on the diagnosis and therapeutic management of these ulcers. Based on the adapted DELPHI methodology, relevant elements were considered in the diagnosis and treatment of chronic leg ulcers of the most common causes; then, the recent literature was analyzed using the best scientific evidence. RESULTS: The following themes were defined as relevant for this consensus - the most prevalent differential etiological diagnoses of chronic leg ulcers (venous, arterial, neuropathic, and hypertensive ulcers), as well as the management of each one. It also included the topic of general principles for local management, common to chronic ulcers, regardless of the etiology. CONCLUSION: This consensus addressed the main etiologies of chronic leg ulcers and their management based on scientific evidence to assist dermatologists and other health professionals and benefit the greatest number of patients with this condition.

Sclerotherapy in the management of varicose veins and its dermatological complications.

BACKGROUND: Varicose veins and its dermatological complications like stasis dermatitis, ulcers, spontaneous bleeding are commonly seen in the dermatology clinics. Surgery has been the most often used treatment for varicose veins. Sclerotherapy refers to introduction of sclerosing solution into the varicose veins, which causes endothelial damage and subsequent fibrosis. Sclerotherapy is being practised extensively by dermatosurgeons in the west. However, there are no Indian studies which specifically evaluate the role of sclerotherapy in the management of varicose veins and its skin complications. Hence, this study aims to evaluate the efficacy of sclerotherapy in managing varicose veins and its complications. AIMS: To study the safety and efficacy of sclerotherapy in the treatment of varicose veins and its dermatological complications. METHODS: This is a prospective study involving 50 patients with varicose veins and its dermatological complications attending the dermatology out-patient department. The study was conducted over a period of 18 months. After thorough clinical, laboratory, and radiological evaluation, the patients were treated with sclerotherapy using Sodium Tetradecyl Sulphate of various concentrations depending on the vessel size. The patients were then followed up to look for disappearance of veins, healing of ulcers and eczema, and any complications. RESULTS: Patients showed a good response to treatment with sclerotherapy. 70-80% of patients showed symptomatic improvement along with disappearance of veins and healing of eczema and ulcers. Most of the complications were minor, which resolved over a period of few weeks. CONCLUSION: Sclerotherapy is a simple, safe and effective procedure for the treatment of varicose veins and its dermatological complications. The procedure is particularly effective for smaller, early varicosities and also for residual veins after surgery. Hence we recommend more and more of our fellow dermatologists to take up this procedure, which can be an efficient tool to manage patients with varicose veins and its related complications.

Contact sensitization in venous eczema: preliminary results of patch testing with Indian standard series and topical medicaments.

BACKGROUND AND AIMS: Elimination of allergens/topical medications causing contact dermatitis in venous eczema, which poses a significant problem in its chronicity and treatment, provides the basis for better therapeutic outcome. Our objective was to determine the pattern of contact sensitization in venous eczema patients in Himachal Pradesh (India). METHODS: Thirty-four patients (M:F, 31:3) and 10 controls (M:F, 6:4) were patch tested with Indian standard series and 10 commonly used topical medicaments. RESULTS: Positive patch test results were seen in 50% (M:F, 16:1) of the patients. Common allergens were Fragrance mix (15%), p-phenylendiamine (15%), nickel (9%), wool alcohol (9%), chinoform (9%), balsum of Peru (5%), cobalt chloride (5%), potassium dichromate (3%), epoxy resin (3%), thiuram mix (3%) and formaldehyde (3%). Only sisomycin and miconazole among the topical medications elicited a positive patch test reaction in 3 and 5% patients, respectively. Neomycin contact sensitivity was not seen in any of the patients. One patient who had exacerbation of venous eczema following accidental application of topical diclofenac showed a positive patch test reaction to it. CONCLUSIONS: Patch test should be used to identify the topical agents that may be responsible for perpetuation or aggravation of eczema, especially in patients who do not improve despite adequate treatment of other underlying cause(s).
