A total of 30 adult patients with AD, with a mean age of 36.07±10.81 years, were enrolled in the study. Firstly, SPT was performed using a standard pineapple allergen extract manufactured by Astromed® (Astromed Inc., West Warwick, Rhode Island, USA). Subsequently, a second SPT was carried out with the pineapple allergen extract produced by Teaching Industry Allergen Dr. Soetomo General Academic Hospital, Universitas Airlangga (Surabaya, Indonesia). Data were analyzed for diagnostic test accuracy and agreement. The local pineapple SPT had a sensitivity of 33.33% and a specificity of 100%. The test exhibited a positive predictive value (PPV) of 100%, whereas the negative predictive value (NPV) was 93.10%. The agreement between the standard SPT and the local SPT was statistically significant, exhibiting moderate concordance (p=0.002). The Indonesian pineapple allergen extract for SPT can serve as an alternative diagnostic tool to assess pineapple allergy and sensitization in AD patients.</p>","PeriodicalId":11049,"journal":{"name":"Dermatology Reports","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145257593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hippocrates of Cos in the 5th century B.C. and later Galen in the 1st century A.D. were the first to refer to skin lesions characterized by scales and itching. In the 19th century, dermatology progressed, gaining scientific autonomy and leading to improvements both in the clinical study of psoriasis and in the search for new treatment methodologies. The dermatological schools established in this century, located in London, Paris, and Vienna, dedicated themselves to studying skin diseases, adopting unique methodological approaches and creating dermatological nomenclature. The English school focused on the objective description of lesions, while the French school was the first to approach the study of evolutionary processes, formulating theories not always based on experimental methods. Finally, the Austrian school based its research entirely on the study of diseases through the use of instruments and laboratory tests. Representatives of all three schools played a crucial role in the scientific progress of dermatology, leading to the subsequent evolution and improvement of therapies, which gradually replaced the use of ancient remedies and archaic administration methods. The treatments promoted by the different 19th-century European dermatologists reflected both their scientific thinking and the medical beliefs of the time.
