Ketoprofen allergic reactions
No full textTopical ketoprofen (KP) is widely used because of its anti-inflammatory effect. Parallel with its popular usage, the number of reported cases of ketoprofen-induced photoallergic contact dermatitis has increased. A review of the literature was made to evaluate the spectrum of cross sensitization in patients with ketoprofen-induced photoallergic contact dermatitis using ketoprofen and other structurally similar chemicals and sunscreens, fragrance components, as well as the presence of prolonged photosensitivity related to it. Furthermore, the distinction between true cross-reactivity and concomitant sensitization may be difficult. Therefore, further investigations are needed to gain a more complete understanding of this important topic. This article also reviews some patents related to alternative treatment of musculoskeletal diseases and/or treatment of allergic reactions due to NSAIDs use
Programmed cell death-1 rs2227981 polymorphism in patients with autoimmune skin blistering disorders: A pilot study
No full textSystemic Contact Dermatitis (SCD) due to dietary nickel
No full textSystemic contact dermatitis (SCD) can be caused by nickel in sensitized subjects. Nickel allergy is commonly characterized by localized reactions ensuring cutaneous exposure to this element. Systemic reactions can occur after dietary nickel ingestion. We report a case of a woman with Systemic Contact Dermatitis due to nickel
Allergic diseases and climate changes: our experience and an update.
No full textRecent research has shown that there are many effects of climate change on aeroallergens and thus allergic diseases in humans. It is not easy to evaluate the impact of climate change and air pollution on the prevalence of allergic diseases. The present study is devoted to decipher the possible relationships between climatic changes and allergic diseases, and in particular with atopic dermatitis (AD). To evaluate the aeroallergens effects on AD, we submitted to an allergological study protocol 59 children patients with AD to study the interaction between aeroallergens-atopy patch test (APT) and skin prick test (SPT). The same tests were performed on to the same patients after 24 months to assess the time trend. We found a high prevalence of house dust mites and grasses pollen APT positivity in AD's and in respiratory patients and we also found an increase in positive results in the same patients after 24 months. However, we observed a variation in the control group, in which in earlier tests all patients had negative results but after 24 months we found some positivity. We found a correlation between APT and SPT in AD and we observed a concordance between APT results and the atopy score index, underlying the triggering role of these aereoallergens in the atopic patient's skin reactivity
A case of sensitization to Alitretinoin
No full textAlitretinoin is a unique retinoid authorised for the treatment of adults with severe chronic hand eczema (CHE) refractory to potent topical steroids. The most common adverse events (AEs) were typical class effects of oral retinoids including headache, flushing and skin disorders. To our knowledge, there are no cases of sensitization to alitretinoin reported in literature. We present a case of sensitization to alitretinoin
Actinic Keratosis Pathogenesis Update and New Patents
No full textBackground Actinic keratosis is a common premalignant skin lesion. Because of increasing incidence of actinic keratosis, several efforts have been done to detect earlier this premalignant lesion and to improve knowledge on photocarcinogenic pathways of keratinocytes. As a consequence, new discoveries have been done in this field recently. Objective Starting from our previous review on actinic keratosis, we reviewed the literature abo this premalignant lesion, focusing on pathogenesis and new patents for its early diagnosis, in order to highlight the most recent progresses in diagnosis and therapeutic approach of actinic keratosis. Conclusion Although several efforts have been done in the field of actinic keratosis, new upgrades in diagnosis and therapy are needed to detect superficial actinic keratosis earlier, to improve the disease free survival of patient and to threat better the field cancerization
LATEX sensitization in elderly: allergological study and diagnostic protocol.
Full text linkBackground: The prevalence of latex allergy varies according to the population studied from 3% to 64%. No data exist in the present literature about elderly people because they were not considered among populations at risk. We report a retrospective observational study of 88 elderly patients of our centre of Dermatology and Allergology at Policlinico Umberto I, University of Rome, Sapienza.Results: First and second level diagnostic tests showed latex positivity in 11,4% of patients studied for latex allergy in the elderly population.Conclusions: Our study demonstrates a prevalence of elderly-latex sensitization of 11,4%, showing that allergy to latex is a growing disease that can occur at any age. So, we propose these patients as an additional risk category for latex allergy. © 2014 Grieco et al.; licensee BioMed Central Ltd
