Low back pain is a common reason for visiting the emergency department (ED), yet little is known about patient motivations for seeking emergency care. The purpose of this study was to explore patient perspectives on visiting the ED for low back pain to inform a more patient-centered approach to emergency care. ⋯ These patient perspectives and resulting themes may be used to inform a more patient-centered emergency care experience and contextualize quantitative research findings on ED care for low back pain.

Pharmacodynamic effect of gabapentin on central nervous system in patients with chronic low back pain: a [99mTc]Tc-ECD SPECT study.
Gabapentin is an effective therapeutic alternative for chronic low back pain, indicated in several guidelines for treating neuropathic pain as first-line medication. This study aimed to describe the pharmacodynamics of gabapentin in the central nervous system of patients with chronic low back pain (CLBP) by using single-photon emission CT (SPECT) with [99mTc]Tc-ECD. ⋯ A lack of improvement in some patients with gabapentin may be associated with an activated affective circuit of pain, evidenced by the increase of rCBF of the anterior cingulate cortex. A maladaptive brain state in chronic pain can explain the decrease of rCBF in the default mode network structures. Gabapentin acts directly or indirectly on neurons of periaqueductal gray substance by increasing the pain threshold and decreasing the rCBF of this structure.

Chronic back pain (CBP) is common among patients in primary care and is associated with significant personal and socioeconomic burden. Research has shown that physical activity (PA) is one of the most effective therapies to reduce pain; however, for GPs it remains challenging to advise and encourage individuals with CBP to exercise regularly. ⋯ To the best of the authors' knowledge, this is the first qualitative study exploring opinion and experience of PA in individuals with CBP and GPs in parallel. This study reveals a complex doctor- patient relationship and provides an important insight to motivation for, and adherence to, PA in individuals with CBP.

Adverse childhood experiences (ACEs) are associated with altered ongoing and evoked pain experiences, which have scarcely been studied for the peripartum period. We aimed to investigate how ACEs affect pain experience in pregnancy and labor. For this noninterventional trial with a short-term follow-up, pregnant women were divided into a trauma group (TG) with ACEs (n = 84) and a control group (CG) without ACEs (n = 107) according to the Childhood Trauma Questionnaire. ⋯ While PPTs increased through delivery in the CG (clinical CPM), and this PPT change was positively correlated with the experimental CPM ( r = 0.55), this was not the case in the TG. The association of ACEs with increased peripartal pain affect and heightened risk for preexisting back pain suggest that such women deserve special care. The dissociation of impaired clinical CPM in women with ACEs and normal prepartum experimental CPM implies at least partly different mechanisms of these 2 manifestations of endogenous pain controls.
