ESID Juniors
“Expect the Unexpected” Junior’s Session
14 October 2026
Dear ESID members,
Due to the huge success and great feedback we have received throughout the last few years, we are now working on the seventh edition of the Juniors Session: “Expect the Unexpected”, which will take place on Wednesday, 14 October 2026 (see the latest version of the programme here).
In recent years, we have not only had very interesting cases, great presentations, outstanding moderators, terrific expert panels, but also exciting discussions that were generated around them. Thus, we decided to include it in a plenary session during the Educational Day and allow the whole audience of the meeting to attend.
If you are an ESID Junior member (*), we invite you to send us an interesting case on inborn error of immunity (**) and have the opportunity to get an oral presentation in a plenary session at the ESID 2026 meeting in Maastricht. Selected presenters will discuss their cases with a top experts’ panel during our interactive workshop!
Presenters of the selected cases will benefit from a FREE REGISTRATION (or reimbursement) to the ESID Meeting 2026.
Submission Instructions
This year, submissions for the ESID 2026 Junior Session “Expect the Unexpected” will be done through an online application form.
Please make sure to fill out and upload all the files requested in the mandatory fields (*), including the following:
- PowerPoint presentation of a maximum of 5 slides summarizing the clinical case.
- 2-minute video briefly presenting your case
- List of your oral presentations at national and international meetings
- Involvement in ESID activities in the past
- Curriculum Vitae
Optional: You can also upload a written abstract (max. 300 words) to include extra information that can be helpful in evaluating the case.
You will have only 13 minutes to present and discuss your case.
Deadline: Thursday, 28 May, 2026
Selection criteria
All the presentations will be evaluated by independent reviewers. Higher scores will be given to those cases where the final diagnosis and/or outcome are UNEXPECTED, considering the initial manifestations. Those cases rising a big discussion around laboratory results will also be highly scored (explaining pitfalls in the laboratory results that can be useful for the audience in their daily practice). The better the case is presented (more precise and clearly illustrated data, confirmed pathogenicity of genetic variants, etc) the higher it will be scored.
We are very much looking forward to receiving your applications!
