Farmers from Paraiba state, Northeast Brazil, claim that Malachra fasciata causes cutaneous lesions in sheep. To test its toxicity the plant was harvested daily and fed ad libitum for 21 days to 3 sheep as the sole food source (# 1-3). An additional sheep (# 4) was maintained as a control. Cutaneous lesions of photosensitization initiated after 7 days and increased continuously over the next 21 days. The dose ingested varied between 129 g/kg to 175 g/kg. Alopecia, hyperemia and crusting were observed in the animals...

Skin is an organ that is susceptible to damage by external injury, chronic inflammation, and autoimmunity. Tissue damage causes alterations in both the configuration and type of cells in lesional skin. This phenomenon, called tissue remodeling, is a universal biological response elicited by programmed cell death, inflammation, immune disorders, and tumorigenic, tumor proliferative, and cytoreductive activity. In this process, changes in the components of the extracellular matrix are required to provide an environment that facilitates tissue remodeling...

Atopic dermatitis (AD) and psoriasis are one of the common skin diseases. Animal models are a powerful tool to analyze these diseases, which are complicated by multiple cytokine pathways. However, many discrepancies between the human diseases and murine models have been noticed. Therefore, investigators should be aware of the differences between the murine AD models and human AD when translating murine data to human skin diseases. This review highlights the differences between the inflammatory profiles between murine models and human diseases focusing on AD and psoriasis...

BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing, inflammatory skin disorder. One of the most disturbing symptoms of AD is pruritus. The first line treatment for AD is topical corticosteroids, topical immunomodulators, topical barrier creams, oral antihistamines, and systemic treatments. Desoximetasone 0.25% spray is a superpotent topical corticosteroid delivered in a novel way and it may be a suitable option for the treatment of pruritus in adult atopic dermatitis patients...

BACKGROUND: Azathioprine is frequently used in severe eczema. It is converted in the liver into active metabolites, including 6-thioguanine nucleotide (6-TGN) and methylated 6-methylmercaptopurine (6-MMP). In the past, the therapeutic potential of azathioprine may have not been fully utilized. Recent investigations on inflammatory bowel disease have led to a better understanding of azathioprine metabolism and optimizing treatment. OBJECTIVE: To investigate whether measuring thiopurine metabolites in circulation can improve the effectiveness and safety of azathioprine treatment in patients with atopic dermatitis and/or chronic hand/foot eczema...

BACKGROUND: Malassezia yeast overgrowth on the skin is a common and often recurrent cause of dermatitis in dogs; it can be an exacerbating factor of atopic dermatitis. Anti-fungal drugs have been a standard treatment, but there is some concern that resistance may be evolving in a spectrum of Malassezia species. Safe, efficient and easy-to-use alternatives are needed. OBJECTIVES: To assess if a commercially available topical non-azole solution applied to paws affected by Malassezia-associated dermatitis (MAD), could ameliorate Malassezia numbers and associated signs over a short term (14 day) trial...

Estrogens and progestins are known to have profound effects on the immune system and may modulate the susceptibility to autoimmune diseases. A comprehensive literature search was carried out using PubMed for any of 153 autoimmune disease terms and the terms contraception, contraceptive, or their chemical components with limits of Humans + Title or Abstract. Over 1,800 titles were returned and scanned, 352 papers retrieved and reviewed in depth and an additional 70 papers retrieved from the bibliographies. Based on this review, substantial evidence exists linking the use of combined oral contraceptives to a lower incidence of hyperthyroidism, an increase in multiple sclerosis, ulcerative colitis, Crohn's disease, Systemic Lupus Erythematosus, and interstitial cystitis...

Hookworm-related cutaneous larva migrans (HRCLM) is caused by the penetration and migration in the epidermis of larvae of Ancylostoma braziliense and Ancylostoma caninum. It is characterized by slightly raised and erythematous tracks, located especially on the feet. These tracks may be single or multiple, serpiginous or linear, ramified and intertwined, accompanied by pruritus. Atypical clinical presentations of HRCLM are currently more frequent than in the past. We present six patients with bullous HRCLM and discuss the possible pathogenetic factors...
