Recertification offers a method of evaluating a diplomate's cognitive knowledge of allergy and immunology. In 1983 candidates for the American Board of Allergy and Immunology recertification examination were offered the entire certifying examination but were informed that they would, for recertification purposes, be held responsible only for a subset of questions judged to be particularly clinically relevant. All 40 candidates elected to take the entire certifying examination. Differences between the performance of certifying and recertifying candidates on the recertifying questions were small. Except for the five-choice questions, the differences in performance between the two groups on the remaining questions were also small in an absolute sense. Recertification performance was not related to the time of original certification. Ninety-eight percent of the candidates completed a questionnaire after the examination. Ninety percent stated that they would encourage their colleagues to participate in the recertification process.

Rigor and reproducibility are vital to scientific advancement. It is unclear whether a protocol optimized for tissue dissociation in one institution performs well universally. Here, we share our brand-new lab's experience with inter-institutional variability that led to the discovery that a protocol optimized for murine lung dissociation at Boston University (BU) fails to reproduce similar CD4 T cell, CD8 T cell, and B cell outcomes at the University of Michigan at Ann Arbor (U-M).

Class I major histocompatibility complex (MHC-I) proteins play a pivotal role in adaptive immunity by displaying epitopic peptides to CD8+ T cells. The chaperones tapasin and TAPBPR promote the selection of immunogenic antigens from a large pool of intracellular peptides. Interactions of chaperoned MHC-I molecules with incoming peptides are transient in nature, and as a result, the precise antigen proofreading mechanism remains elusive.

Background: Food protein-induced allergic proctocolitis is a nonimmunoglobulin E-mediated, self-limited food allergy of the rectum and the colon. Cow's milk protein is the most common allergen responsible for the disease.
Objective: This study aimed to investigate the roles of different types of formulas in building early tolerance to food protein-induced allergic proctocolitis in infants.

Drug-induced enterocolitis syndrome (DIES), little known due to its recent description, is analogous to food protein-induced enterocolitis syndrome (FPIES). Both processes are more frequent in pediatric age and share diagnostic criteria, the main one being the appearance of persistent vomiting 1-4 hours after ingestion of the drug or food, in the absence of IgE-mediated allergy symptoms.

Background: Hymenoptera venom allergy is a potentially severe allergic reaction in the general population. The only preventative approach in these cases is venom immunotherapy (VIT), which follows different protocols. The recommended initial dose is 0.
