Diagnosis of perioperative anaphylaxis is difficult because of its non-specific and variable signs and symptoms. Therapeutic agents used to treat anaphylaxis and anaesthesiologist responses also vary depending on the case, which might affect outcomes; however, only a few studies have focused on these factors. ⋯ UMIN000035350.

Diagnosis of perioperative anaphylaxis is often challenging. This study describes the utility of a newly developed tool for identifying patients with a high possibility of anaphylaxis, and aimed to investigate the frequency of anaphylaxis with each drug during the perioperative period in Japan. ⋯ UMIN000035350.

We provide a commentary on aspects of a prospective study of the epidemiology of perioperative anaphylaxis in Japan (Japanese Epidemiologic Study for Perioperative Anaphylaxis [JESPA]). Accurate diagnosis of perioperative anaphylaxis is important for research but essential for clinical safety. We evaluate the diagnostic approach used in the JESPA study and caution against over-reliance on diagnostic tests that lack sensitivity and specificity when clinical data suggest an immediate perioperative hypersensitivity reaction is likely.

'Where there's smoke': longitudinal cognitive disintegration after postoperative delirium?
Postoperative delirium is an important complication of surgery and is associated with poor long-term cognitive outcomes, although the neural basis underlying this relationship is poorly understood. Neuroimaging studies and network-based approaches play an important role in our understanding of the mechanism by which delirium relates to longitudinal cognitive decline. A recent resting state functional MRI study is reviewed, which shows reduced global connectivity up to 3 months after delirium, supporting recent models of delirium and opening the door for applying this approach to understanding the complex inter-relationship between delirium and dementia.
