Subcutaneous Immunotherapy Safety: Incidence per Surveys and Risk Factors.

Subcutaneous immunotherapy (SCIT) is effective for allergic rhinitis and conjunctivitis, asthma, and insect venom hypersensitivity. The risk of severe allergic reactions induced by SCIT remains low, and mild systemic reactions have recently shown a tendency to decline. However, near-fatal and fatal anaphylactic reactions may occur.

Thyroid cancers express CD-40 and CD-40 ligand: cancers that express CD-40 ligand may have a greater risk of recurrence in young patients.

The immune response might suppress thyroid cancer recurrence. Although the factors that control this are unknown, CD-40 and CD-40 ligand might be important. To test this, we stained 36 papillary (PTC) and four follicular (FTC) thyroid carcinomas for CD-40 (n = 37) and CD-40 ligand (n = 36) and graded staining from absent (grade 0) to intense (grade 3).
