Systematic review of the efficacy and purpose of student surgical interest groups.

BACKGROUND: There is concern around projected unmet need in the surgical workforce internationally. Current barriers to medical students pursuing surgical careers include lack of early exposure, low confidence in surgical skills, and perceived lifestyle barriers. This review aimed to examine both the purpose of student surgical interest groups (SIGs) globally, and their effect on metrics representing student surgical career interest. barriers. METHODS: MEDLINE, EMBASE, PubMed, and Google Scholar were searched for papers analysing surgical interest group purpose and efficacy. Risk of bias was assessed for survey-based papers using a 20-point checklist. Descriptive analysis was performed based on qualitative data. RESULTS: Twenty-eight papers were included in the analysis including 13 surveys. These were of moderate quality. The analysed SIGs had 100-1000 student members and a diverse range of funding sources. Purpose of SIGs was described by 26 of 28 papers with common themes including promotion of surgical career choice and developing theoretical/practical surgical skills. Common initiatives of SIGs included surgical lectures/teaching and practical skills workshops. Data from 15 papers analysing efficacy of SIGs suggested they positively influenced self-reported student interest in surgical careers (78.6%) and confidence in surgical knowledge (80%), as well as confidence in practical skills, knowledge about surgical careers/lifestyle, mentorship opportunity, and research involvement. CONCLUSION: Student SIGs make a unique contribution to early medical student experience through positive effect on promoting surgical careers. They target relevant metrics such as surgical knowledge and confidence that are known to influence surgical career choice in the modern surgical landscape.

Patch testing to plants: sensitisation associated with exposure to plants, essential oils and botanicals in cosmetics.

BACKGROUND: Contact allergy to plants, particularly Compositae, presents with dermatitis and is diagnosed with skin patch testing. Sesquiterpene lactone mix is a common screening allergen for plant allergy. The rate of plant allergen sensitisation in New Zealand, which is affected by local horticultural factors, has not previously been documented. AIMS: To investigate the rate of plant allergen sensitisation in New Zealand's regional population, characterise common allergens and reassess appropriate allergens for patch testing. METHODS: Retrospective analysis of patient demographics and patch-test results over an eight-year period (2012 to 2020) was performed at a tertiary patch-test clinic in Auckland, New Zealand. RESULTS: 820 patients completed patch testing. There was a 12.9% sensitivity rate (a positive reaction on patch testing) to at least one plant allergen and a 6.2% plant allergy rate (positive reaction of current relevance). The most frequent positive reactions were Myroxylon pereirae (n=38), colophonium (n=35) and sesquiterpene lactone mix (n=14). Of patients with a plant allergy (n=51), the allergy source was a botanical in a cosmetic product in 27 cases (52.9%), a plant in ten (19.6%) and an essential oil in two (3.9%). CONCLUSIONS: Reactions to plant allergens were related to botanicals in cosmetics and creams, plants and essential oils. Rates of plant sensitisation in our cohort are comparable with international data.

Topical corticosteroid allergy: Results of sequential testing to a corticosteroid series in New Zealand.

BACKGROUND: Our institution tests the European Baseline Series (EBS) and a steroid series sequentially in all patients presenting for patch testing. The rate of steroid sensitization in New Zealand has not previously been documented. OBJECTIVES: To investigate the rate of corticosteroid sensitization and assess additional benefit of testing the full steroid series over the steroid allergy markers in the EBS. METHODS/PATIENTS: Retrospective analysis of all patient demographics and patch test results over a 5-year period (2014 to 2019) was performed at a tertiary patch test clinic in Auckland, New Zealand. RESULTS: A total of 319 patients completed patch testing, and 4.4% were sensitized to one or more corticosteroids. As much as 79% of positive reactions were of current relevance; 11/14 reactions were to tixocortol pivalate or budesonide. The "number needed to test" to detect one additional case of corticosteroid sensitization by using the full corticosteroid series over the EBS alone was 107. CONCLUSIONS: Although corticosteroid sensitization was not uncommon in our population, the results suggest that sequential testing with the corticosteroid markers (budesonide and tixocortol) in the standard series alone is adequate. The additional corticosteroid series should be added if the markers are positive or where there is a clinical suspicion of corticosteroid allergy.
