An emerging epidemic of allergic contact dermatitis due to phytonadione epoxide (oxidised vitamin K1).

Background: Reports of allergic contact dermatitis (ACD) to phytonadione epoxide (PE) in cosmetics suggest that PE is as powerful a sensitiser as its parent compound phytonadione.

Objective: To evaluate a case series of ACD to PE in Spain.

Methods: We reviewed the records of 20 patients with ACD to cosmetics containing PE diagnosed across Spain between January 2019 and June 2023.

Multidisciplinary management of type 2 inflammation diseases using a screening tool.

Dysregulation of type 2 (T2) immune response leads to an aberrant inflammatory reaction that constitutes the pathophysiological basis of diseases involving various organs. For this reason, several disorders can coexist in a single patient; however, as different specialists often treat these pathologies, T2 dysregulation, particularly when mild, is not always the first diagnostic suspicion. A breakdown in interdisciplinary communication or the lack of adequate tools to detect these entities can delay diagnosis, and this, together with a lack of coordination, can lead to suboptimal care.

A Qualitative Tool to Guide in the Interpretation of the Numerical Rating Scale for Pruritus Intensity in Patients with Atopic Dermatitis.

Atopic dermatitis is a cutaneous inflammatory disease characterized by intense pruritus, which is often underestimated despite its direct impact on patients' health-related quality of life and the high burden it poses. The authors' goal was to design a qualitative tool to guide patients and healthcare professionals in their assessment and interpretation of pruritus intensity using a numerical rating scale. The draft of this tool, henceforth "guideline", was developed based on a systematic literature review and focus groups comprising patients and a scientific committee.

2-Hydroxyethyl methacrylate (2-HEMA) sensitization, a global epidemic at its peak in Spain?

Background: A global epidemic of allergic contact dermatitis to (meth)acrylates has been described in relation to the widespread use of manicure products.

Objectives: To evaluate the frequency of sensitization to 2-hydroxyethyl methacrylate (2-HEMA) among consecutively patch tested patients with eczema in Spain; the percentage of current relevance; the MOAHLFA index; and, the potential sources of exposure to (meth)acrylates.

Methods: From January 2019 to December 2022, 2-HEMA 2% pet.

Pruritus and Pain Constitute the Main Negative Impact of Atopic Dermatitis® From the Patient's Perspective: A Systematic Review.

Atopic Dermatitis® (AD) is an inflammatory skin disease characterized by intense itching and highly visible signs, representing a great burden to the patient. Despite its straightforward diagnosis, AD severity and burden can be underestimated in routine clinical practice. This review aims to determine the impact of AD on patients' lives, establish which domains of life are most affected, and identify symptom drivers of AD burden.

Candidate Allergens for Inclusion in the Spanish Standard Series Based on Data from the Spanish Contact Dermatitis Registry.

Background: Standard patch test series must be updated using objective data on allergen sensitization. The Spanish standard series was last updated in 2016 and the European series in 2019, and the inclusion of several emerging allergens needs to be evaluated.

Material And Methods: We conducted a prospective, observational, multicenter study of consecutive patients from the registry of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) who were patch tested in 2019 and 2020 with linalool hydroperoxide, limonene hydroperoxide, 2-hydroxyethyl-methacrylate, benzisothiazolinone, octylisothiazolinone, textile dye mix (TDM), sodium metabisulfite, propolis, bronopol, Compositae mix II, diazolidinyl urea, imidazolidinyl urea, decyl glucoside, and lauryl glucoside.

Pain and analgesic drugs in chronic venous ulcers with topical sevoflurane use.

Objective: Pain in chronic venous ulcers (CVUs) notably increases with the usual cleaning of the wound. Chronic pain is usually poorly controlled even with the multiple analgesic treatments available. Analgesics can have different serious adverse effects and medical interactions in old patients with several comorbidities.

Healing of chronic venous ulcer with topical sevoflurane.

The present study assesses the efficacy and safety of topical sevoflurane in chronic venous ulcers and its impact on analgesia and healing. This retrospective study included 30 patients older than 65 years with painful refractory chronic venous ulcers. Patients were treated with topical sevoflurane prior to the usual ulcer cleaning every 2 days for a period of 1 month.

Topical sevoflurane for chronic venous ulcers infected by multi-drug-resistant organisms.

Several anaesthetic drugs have demonstrated antibacterial properties in vitro. Anaesthetics can primarily affect the cell wall of both susceptible and multi-resistant bacteria. They may also have a synergistic effect with conventional antibiotics through an unknown mechanism.

Alpha-1-antitrypsin deficiency panniculitis.

Alpha-1-antitrypsin deficiency is a congenital error of metabolism linked to pulmonary (emphysema) and liver (cirrhosis) disease. Since 1972, panniculitis has been associated with this deficiency, initially related to Weber-Christian syndrome and finally as a differentiated entity. Clinical manifestations typically consist of wide nodular lesions on the trunk and proximal extremities that evolve to ulceration and drainage.
