The influence of inflammatory pain and/or weaning stress at different terms of neonatal development on functional activity of the nociceptive system during adulthood was studied in rats. Repeated stress in 1-2-day-old rat pups (a premature baby model) enhanced pain sensitivity to peripheral inflammation in both males and females. Repeated inflammatory pain experienced by male pups aged 1-2 or 7-8 days (models of preterm and full-term baby), even in presence of mother, enhanced pain behavior under conditions of repeated inflammatory pain in adulthood. Pain sensitivity in adult animals before (hot plate test) and after formation of the inflammatory focus (formalin test) depended on the age when the animals were subjected to the injury, type of exposure, and on animal sex. The priority data obtained by us will help to understand the mechanisms of long-term effects of early injuries and are important for pediatricians and neonatologists.

A child with Chronic Nonbacterial Osteomyelitis and celiac disease: accidental association or two different aspects of the same condition?

Background: Chronic Nonbacterial Osteomyelitis (CNO) is a rare auto-inflammatory disease that mainly affects children, and manifests with single or multiple painful bone lesions. Due to the lack of specific laboratory markers, CNO diagnosis is a matter of exclusion from different conditions, first and foremost bacterial osteomyelitis and malignancies. Whole Body Magnetic Resonance (WBMR) and bone biopsy are the gold standard for the diagnosis.

CT-guided C1-C2 facet joint injections are a valuable tool for managing cervicogenic headaches caused by degenerative and inflammatory conditions of the atlantoaxial joint. This video article presents the procedural technique for a CT-guided C1-C2 facet joint injection in a patient with left-sided cervicogenic headache. Despite concerns regarding potential complications such as vascular injury to the vertebral artery and nerve injury to the C2 dorsal root ganglion, careful anatomic planning and imaging guidance allows safe and effective treatment.

Loss of GABAergic inhibition in the spinal dorsal horn (SDH) is implicated in central sensitization and chronic pain. Both agonists and positive allosteric modulators (PAMs) of GABAA receptor are found to be effective in the management of chronic pain. In addition to benzodiazepines, neuroactive steroids (NASs) also act as PAMs through binding to unique sites of GABAA receptors.

Electronic address:
Chronic pain and depression exhibit a high comorbidity, are challenging to manage, and their pathophysiology mechanisms are intricated and closely related to the up-regulation of pro-inflammatory response and oxidative stress. Chronic pain and depression often coexist and present significant management challenges. Their underlying pathophysiological mechanisms are complex and closely linked to the up-regulation of pro-inflammatory responses and oxidative stress.

The central amygdaloid nucleus (CeA) and the lateral habenular nucleus (LHb) are essential nuclei playing modulatory roles in encoding noxious stimuli. Their interaction has recently been demonstrated in chronic pain-induced depression. However, little is known about the CeA-LHb pathway in a formalin-induced pain model.
