[source] Allergic contact dermatitis from modified colophonium in wound dressingsCONTACT DERMATITIS, Issue 1 2007Teresa M. Pereira This study concerns a 69-year-old female patient with a longstanding history of venous ulcerations on both lower legs and multiple sensitivities, who developed eczematous lesions with the hydrocolloid dressing Combiderm® (Convatec Ltd., a Bristol-Myers Squibb division, Ickenham, Middlesex, UK). Epicutaneous tests were positive to this dressing and to a modified colophonium derivative, i.e. glyceryl rosinate, however not to the unmodified colophonium from the standard series. A review of the literature showed several case reports about sensitization to similar hydrocolloids being distributed under various brand names in different countries and which contain the pentaerythritol ester of the hydrogenated rosin as the tackifying agent. Some of the patients described did, while others did not, react to colophonium but only to a modified derivative. In our patient, the reaction to glyceryl rosinate most probably represent cross-sensitivity with the modified colophonium derivative used in Combiderm®, the presence (but not the exact nature) of which was showed by the company. In patients where allergic contact dermatitis from hydrocolloid dressings is strongly suspected and colophonium tests negatively, patch testing to modified colophonium derivatives should therefore be performed. As the complete composition of wound dressings is most often unknown, we urgently advocate legal requirements for labelling of those and in fact all medically used devices. [source] Use of Honey as an Adjunct in the Healing of Split-Thickness Skin Graft Donor SiteDERMATOLOGIC SURGERY, Issue 2 2003Aykut Misirlioglu MD BACKGROUND Different techniques are being used in treatment of split-thickness skin graft donor sites; however, there is not a widely accepted method established for these partial-thickness wounds. It is well known that honey has been very effective in the treatment of various types of wounds, but there is not any information about the usage of honey as split-thickness skin graft donor site dressing in the literature. OBJECTIVE To evaluate and compare the effectiveness of honey-impregnated gauzes, hydrocolloid dressings, and as a conventional dressing, saline-soaked gauzes for skin graft donor sites. METHODS This is a nonrandomized, prospective, open-label (noncontrolled), side-by-side comparison trial of various options that are available for second-intention healing of donor site for split-thickness skin grafts. Eighty-eight patients who underwent skin grafting were observed using two different groups. In the first group, the donor site was divided into two equal halves, with each half being treated with honey-soaked gauzes and the other half with paraffin gauzes (group 1A), hydrocolloid dressings (group 1B), and saline-soaked gauzes (group 1C) alternatively. In the second group, two separate donor sites were formed, with one of them being treated with honey-impregnated gauzes (groups 2A,C) and the other one treated with either paraffin gauzes (group 2A), hydrocolloid dressings (group 2B), or saline-soaked gauzes (group 2C). The healing time, rate of infection, and sense of pain were evaluated. RESULTS In the treatment of split-thickness skin graft donor sites, honey-impregnated gauzes showed faster epithelization time and a low sense of pain than paraffin gauzes and saline-soaked gauzes. There was no significant difference between honey-impregnated gauzes and hydrocolloid dressings with regard to epithelization time and sense of pain. CONCLUSION The use of honey-impregnated gauzes is effective, safe, and practical. Honey can be an alternative material for the split-thickness skin graft donor site treatment. [source] Leg ulcers and hydroxyurea: report of three cases with essential thrombocythemiaINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2002Zeynep Demirçay MD Case 1,A 65-year-old woman with essential thrombocythemia (ET) had been taking oral hydroxyurea (HU), 1000 mg daily, for 7 years. Six months ago, she developed an ulcer on the outer part of her left ankle, which healed spontaneously within 2 months. She presented with a new, tender, shallow ulcer, 2 cm × 2 cm in size, at the same site. Doppler examination revealed thrombosis of the left common femoral vein and a calcified atheroma plaque of the left common femoral artery. The dosage of HU was decreased to 500 mg daily when the platelet counts were found to be within normal levels. The ulcer completely healed within 2 months with occlusive wound dressings, and has not recurred within the follow-up period of 1 year. Case 2,A 56-year-old women presented with multiple, painful, leg ulcers of 1 year duration. She had been diagnosed as having ET and had been on HU therapy, 1500 mg/day, for the past 5 years. Interferon-,-2b was started 3 months ago, in addition to HU, which was tapered to 1000 mg daily. She had suffered from hypertension for 20 years treated with nifedipine and enalapril, and had recently been diagnosed with diabetes mellitus which was controlled by diet. Examination revealed three ulcers located on the lateral aspects of both ankles and right distal toe. Arterial and venous Doppler examinations were within normal limits. Histopathology of the ulcer revealed nonspecific changes with a mixed inflammatory cell infiltrate around dermal vessels. The ulcers completely healed within 10 weeks with topical hydrocolloid dressings. After healing, she was lost to follow-up. A year later, it was learned that she had developed a new ulcer at her right heel, 3 months after her last visit (by phone call). This ulcer persisted for 8 months until HU was withdrawn. Case 3,A 64-year-old woman with ET presented with a painful leg ulcer of 6 months' duration. She had been taking oral HU for 5 years. She had a 20-year history of hypertension treated with lisinopril. Examination revealed a punched-out ulcer of 2 cm × 2 cm over the right lateral malleolus (Fig. 1). Doppler examination of the veins revealed insufficiency of the right greater saphenous and femoral veins. Angiography showed multiple stenoses of the right popliteal and femoral arteries. As her platelet count remained high, HU was continued. During the follow-up period of 13 months, the ulcer showed only partial improvement with local wound care. Figure 1.

The patient was treated by occlusion with hydrocolloid dressings. Considerable subjective and objective improvement was observed with respect to the pruritus and cosmetic appearance. We suggest this convenient and efficacious treatment as first line therapy. [source] | ||||||||||
