Inappropriate tick removal techniques are known to trigger tick anaphylaxis. This study aimed to ascertain the evidence for the effectiveness of tick removal methods and their relationship to the outcomes of tick-induced allergies and tick-borne illnesses. The design involved is a systematic literature review. Scopus, Embase, and Medline were searched (September 20, 2023) for studies of tick removal techniques and for outcomes of tick-induced allergic reactions and tick-borne illnesses. Two reviewers reviewed abstracts and full texts. Included studies were appraised (Joanna Briggs Institute critical appraisal tools), and data were extracted, tabulated, and evaluated. Six studies investigated a relevant outcome, all of low or moderate quality. Tick-killing in situ before removal resulted in allergic reactions in only 3/61 patients and no anaphylaxis. 23/28 who presented to the Emergency Department following removal with tweezers had allergic reactions (one anaphylaxis). When those with known tick anaphylaxis killed ticks in situ before removal there was no subsequent anaphylactic reaction. A significant decrease in disease transmission and/or seropositivity (<i>B. burgdorferi</i> and/or <i>R. conorii</i>) was shown with crushing ticks or gentle pressure before removal with fine-tipped forceps, forceps alone, and surgical tweezers. Manipulation before removal with tweezers made no difference to <i>B. burgdorferi</i> seropositivity. Few studies worldwide have examined outcomes of tick removal techniques. Tick-killing in situ reduces recurrent tick anaphylaxis in Australians. Early removal with forceps may be effective where tick-borne disease is of greater concern. Further studies of tick-killing in situ focusing upon disease transmission should be prioritized.</p>","PeriodicalId":8488,"journal":{"name":"Asia Pacific Allergy","volume":"15 4","pages":"329-335"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12672175/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145666457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe cases, characterized by high milk-specific IgE levels and a history of anaphylaxis, rarely develop natural tolerance. Oral immunotherapy (OIT) is generally avoided in such high-risk patients due to the risk of serious allergic reactions, leaving strict avoidance as the standard treatment. However, prolonged avoidance may delay tolerance acquisition and increase psychosocial burden. We report a female patient with severe CMA and multiple food allergies who underwent a carefully tailored, ultra-low-dose OIT over 10 years. At treatment initiation, her milk-specific IgE was >100 kUA/L, and an oral challenge with 1.1 mL of milk induced anaphylaxis. The OIT protocol started with a dose well below her reaction threshold and increased gradually, resulting in no serious adverse events. Over time, she achieved tolerance to 200 mL of pure milk and resumed unrestricted consumption of milk and other previously avoided foods such as egg and wheat. This is the first report of successful long-term ultra-low-dose OIT in a highly sensitized child with severe CMA, showing that slow, cautious escalation can safely induce unrestricted intake even in patients previously deemed unsuitable for OIT. Given the limitations of biologics and emergency care availability worldwide, this low-risk, home-based protocol using locally available foods offers a feasible and affordable approach for managing severe food allergies globally. Such individualized, sustained OIT may improve long-term outcomes and quality of life for children with severe food allergies.</p>","PeriodicalId":8488,"journal":{"name":"Asia Pacific Allergy","volume":"15 4","pages":"336-339"},"PeriodicalIF":2.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12672171/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145666827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also plays a decisive role in diagnosing overlapping rhinitis, a frequent cause of treatment failure. In CRSwNP, NC has contributed to defining the eosinophil-mast cell endotype and to developing the Clinical-Cytological Grading (CCG) and the Prognostic Index of Relapse (PIR), both correlating with disease severity and recurrence risk, while also aiding in the selection of candidates for biologic therapies.
