We read with deep interest the report by Tepasse and colleagues 1 , concerning two cases of persisting viremia in Covid‐19 with fatal outcome. Whilst SARS‐CoV‐2 infection in the early stages of infection has been well described, less is known about the development of antibodies to SARS‐CoV‐2, clearance of RNA shedding and clinical outcome of COVID‐19.

Confirmation has been obtained that reducing the content of natural free alcohols in lanolin to below 3%, particularly in the absence of detergent residues, reduces the incidence of positive patch test reactions amongst selected lanolin-sensitive skin patients by 99.3%. Only one reaction out of 149 subjects was recorded.

Background: Anaphylaxis is a recognized public health issue. There is no doubt that food-induced anaphylaxis (FIA) has tremendous impact on the quality of life of patients and their families and increases direct and indirect costs. FIA is associated with increasing rates of emergency department admissions and hospitalizations and implies the risk of death. Morbidity epidemiological data are a key to tailor public | 1731 TANNO eT Al.

K E Y W O R D S : airborne, allergic contact dermatitis, artichoke, case report, plant, sesquiterpene lactones CASE REPORTS Case 1. A 71-year-old nonatopic woman was referred for evaluation of erythematous and edematous lesions on her face and left forearm with scaling during the following days (Figure 1). She reported a similar episode the year before, during the same season, around March. Both episodes occurred shortly after she handled artichokes and cardoons (artichoke thistle; Cynara cardunculus) in her garden. Patch tests were performed on the upper back using IQ Ultra chambers (Chemotechnique Diagnostics, Vellinge, Sweden) occluded for 2 days with Opertape (Iberhospitex, Innovative Health Technologies, Barcelona, Spain). The European baseline series was tested along with additional series from the réseau de vigilance en dermato-allergologie group, a plant series (except for Taraxacum officinale and Tanacetum vulgare extracts), the leaf and stalk of common artichokes "as is," and were read on day (D) 2 and D4 according to the ESCD recommendations. 1 Positive reactions with sesquiterpene lactone (STL) mix 0.1% pet. (+ on D2, ++ on D4), Compositae mix (CM) II 5% pet. (++ on D2 and D4), Chrysanthemum cinerariaefolium extract 1.0% pet. (+ on D2, ++ on D4), parthenolide 0.1% pet. (+ on D4), and to artichoke leaf (+ on D2, ++ on D4) were observed (Figure 2(A)).Cardoon was not tested.Case 2. A 41-year-old man with a history of seasonal rhinoconjunctivitis was referred for severe eczematous lesions on his face, neck, and forearms (Figure 3). Cutaneous lesions relapsed whenever he worked as a seasonal employee in a farming cooperative (where he had been working for 4 years), mainly handling artichokes.The same patch tests series as in the previous patient were tested, and positive test reactions to methyldibromo glutaronitrile 0.5% pet.(+ on D3), STL mix 0.1% pet. (++ on D3), CM II 5% pet. (?+ on D3), artichoke stalk (+ on D2 and D3), and to dried artichoke stalk and leaf (+ on D2 and ++ on D3) (Figure 2(B)) were observed. No skin relapse was observed after he stopped handling artichokes, although he continued to work in the same place.
