Rare Immune-Related Adverse Events (irAEs): Approach to Diagnosis and Management.

Immune checkpoint inhibitors (ICIs) have revolutionised the treatment landscape across many solid organ malignancies and form part of routine clinical practice in many tumours. As indications for monotherapy, doublet therapy and combination approaches with chemotherapy and targeted agents expand, clinicians must be aware of the wide range of possible immune-related adverse events (irAEs). Common toxicities, including rash, colitis, hepatitis and pneumonitis are well described in the literature, and have established diagnostic and management algorithms.

Sunitinib-Induced Adrenal Crisis in a Patient with Pre-Existing Immunotherapy-Related Hypopituitarism.

Sunitinib is a tyrosine kinase inhibitor that is frequently used in the treatment of metastatic renal cell carcinoma (mRCC). As a multikinase inhibitor, numerous off-target side effects of this medication are widely recognized. More recently, endocrine side effects, including hypoadrenalism, are becoming more apparent.

Changes in skin blood flow, respiration and blood pressure in participants reporting motion sickness during sinusoidal galvanic vestibular stimulation.

New Findings: What is the central question of the study? We have previously shown that sinusoidal galvanic vestibular stimulation induces greater modulation of skin sympathetic nerve activity, but not muscle sympathetic nerve activity, in participants who report nausea during simulated motion, but the effects on skin blood flow and blood pressure are unknown. What is the main finding and its importance? During vestibular stimulation, nausea was associated with a greater increase in skin blood flow and a progressive reduction in skin sympathetic nerve activity, but no changes in muscle sympathetic nerve activity. This emphasizes the differential changes in sympathetic outflow to different tissues during nausea.
