As regards the central one, Beltramo et al., [40] demonstrated that AM1241 reduces capsaicin-induced CGRP release in dorsal root ganglia (DRG), confirming that CB2 activation may elicit cause analgesia by acting not only at non-neuronal peripheral sites but also at the neural level.
Despite a number of eliciting causes all patients had significant overlap in symptoms and orthostatic headache as their core symptom.
Two patients reported physical trauma as the eliciting cause.

Nine patients presented with symptoms of spontaneous intracranial hypotension (SIH), hereof two patients with a history of tension type headache and medication overuse headache, and another two patients reported Valsalva maneuver (sneeze, labor) as eliciting cause.
To the best of our knowledge, this is the first published case of HLH to occur after cardiac surgery but without a known eliciting cause.
In addition, while the effects on cognitive processing elicited caused by the use of images, as compared to text, within item response formats has been previously reported, the authors are unaware of any studies using similar methodology to examine the effects of integrating images into the stimulus format, which could potentially be more influential [ 44].

A recent survey of British women aged 16 97 used an open question to elicit the causes of cervical cancer; only 2.5% mentioned HPV and 7% mentioned an unspecified sexually transmitted virus/infection [ 28].
Future studies using qualitative research methods such as focus group discussion should be conducted to elicit the causes for the poor sensitivity to difference of the Chinese version of the EQ-VAS.
