BACKGROUND: Chronic eczema such as atopic dermatitis imposes significant socio-econo-psychologic burdens on the affected individuals. In addition to conventional topical treatments, phototherapy is recommended for patients with extensive lesions. Although immunosuppression is believed to explain its primary effectiveness, the underlying mechanisms of phototherapy remain unsolved. Ultraviolet irradiation generates various tryptophan photoproducts including 6-formylindolo[3,2-b]-carbazole (FICZ)...

Vitamin D3 (VD3 ) analogues-containing ointments are known to occasionally cause hypercalcemia in psoriasis patients, and the frequency of hypercalcemia is suggested to vary based on the VD3 analogue used. In this study, to address the differences in calcemic effects of VD3 -containing ointments, the calcemic effects of marketed VD3 -containing ointments, including calcipotriol (Cal), maxacalcitol (Max), tacalcitol (Tac), calcipotriol/betamethasone dipropionate (Cal/BDP) and maxacalcitol/betamethasone butyrate propionate (Max/BBP) ointments, were evaluated in a rat model of imiquimod-induced dermatitis...

The Lando® dermal scaffold is a newly developed, tissue-engineered dermal scaffold material. This study sought to observe its vascularization in an acute full-thickness skin-defect porcine model. There were eight Tibetan pigs in this research. Six 5 × 5 cm full-thickness skin-defect wounds were prepared on the dorsal area of each pig, which were divided into two groups. The experimental group wounds were covered by Lando® dermal scaffolds, while the other received Vaseline gauzes as blank control. At day 3, 7, 14 and 21 after injury, the general condition of wounds was observed, and wound specimens were obtained for HE staining, Masson staining and the expression of CD31, α-SMA and VEGF, which were examined by immunohistochemistry...

Objective: To evaluate the wound-healing activity of oil of Hypercium perforatum (St. John's wort), in excision wounds of male white rats. Approach: The current methods of wound management involve the use of antibiotic creams. The search for more natural materials for the purpose of healing of wounds has led to the discoveries of potential agents prepared from plant extracts. Hyperforin and Hypericin are important phytochemical constituents found in H. perforatum, which have been highlighted for their antimicrobial, antiviral, and anti-inflammatory properties in recent times...

BACKGROUND: The authors want to evaluate the efficacy of fibrillary tabotamp dressing in skin graft-donor site. A comparison was made with Vaseline gauzes. Tabotamp is an absorbable haemostatic product of Ethicon (Johnson and Johnson) obtained by sterile and oxidized regenerated cellulose (Rayon). It is used for mild to moderate bleeding. MATERIALS AND METHODS: 276 patients were subject to skin graft and divided into two group: Group A and Group B. The donor site of patients in Group A was medicated with fibrillary tabotamp, while the patients of Group B were medicated only with Vaseline gauze...

BACKGROUND: Allicin, the active component of garlic, has been shown to have antimicrobial and anti-inflammatory properties. Garlic has also been used historically by many cultures to heal wounds. Several animal studies have shown that garlic extracts increase the rate of wound healing and decrease the rate of infection. OBJECTIVE: Fibroblasts play a key role in wound healing. Here we hypothesize that fibroblasts are being activated by allicin, leading to more organized and rapid wound repair...

PURPOSE: To investigated the inflammatory, angiogenic and fibrogenic activities of the Schinus terebinthifolius Raddi leaves oil (STRO) on wound healing. METHODS: The excisional wound healing model was used to evaluate the effects of STRO. The mice were divided into two groups: Control, subjected to vehicle solution (ointment lanolin/vaseline base), or STRO- treated group, administered topically once a day for 3, 7 and 14 days post-excision. We evaluated the macroscopic wound closure rate; the inflammation was evaluated by leukocytes accumulation and cytokine levels in the wounds...

Background Psoriasis is a chronic inflammatory skin disorder of unknown etiology. Increasing evidence suggests that psoriasis is probably an angiogenesis-dependent disease. Thalidomide has been reported being able to inhibit the effects of fibroblast growth factor 2 and vascular endothelial growth factor (VEGF), and inhibit tumour necrosis factor-alpha synthesis, and suppress tumour necrosis factor-induced nuclear factor-kappa B activation in Jurkat cells, resulting in suppression of proliferation inflammation, angiogenesis, and the immune system, which are related to the pathogenesis of psoriasis...

This study was designed to assess the efficacy of vacuum sealing drainage (VSD) on skull exposure wounds in rabbits and to investigate the underlying mechanism of the process. Full-thickness excisional circular wounds 2×2 cm with or without periosteum involvement were created in 88 New Zealand white rabbits (mean body weight: 3.0±0.65 kg). Animals were randomly divided into 4 groups: periosteum-intact wounds treated with traditional dressing (p+control), periosteum-intact wounds treated with VSD (p+VSD), periosteum-lacking wounds treated with traditional dressing (p-control) and periosteum-lacking wounds treated with VSD (p-VSD)...

This cross-sectional study was conducted in Antananarivo, Madagascar, from June to September 2012. We aim to evaluate the misuse of TC on the face for cosmetic purpose and the adverse effects due to its application. A questionnaire-based analysis was done among females who use topical corticosteroids on the face for cosmetic purpose. Of the 770 women questioned, 384 (49,8%) used topical corticosteroids for cosmetic purpose whose mean age was 38 years (range 16-73 years). Two hundred and sixty-one females (68%) used TC combined with handcrafted cosmetics, and 123 (32%) used TC alone...

BACKGROUND: Myiasis designates the infestation of live human and vertebrate animals with dipterous (two-winged) larvae (maggots) and is the fourth most common travel-associated skin disease. Furuncle is the most common aspect of cutaneous myiasis. CASE PRESENTATION: A 24-year-old Caucasian female had been back from Cap-Vert. She described pruritus, slight pain, and the sensation of a foreign body moving in the eyelid. Physical examination showed a single furuncle-like nodule with surrounding erythema and a central pore of the upper eyelid through which a serosanguinous fluid was exuding...
