For decades, clinicians and researchers have observed bidirectional relationships between child development and the pain experience in childhood. Pain in childhood is an inherently developmental phenomenon, embedded in an iterative, time-dependent process that reflects individual biological, behavioral, social, psychological, and environmental characteristics that unfold across the early life span. Childhood pain can have wide ranging effects on brain development in ways that contribute-for better and worse-to social, emotional, and cognitive well-being in childhood and on into adulthood. ⋯ In this paper, pain will be considered as a determinant of development, and conversely development will be considered as a key determinant of a child's pain experience. We will discuss how intersectional identities (eg, gender, race, socioeconomic status) and associated social, structural, systemic, and physical environments influence the relationship between development and pain. Finally, we will identify what might be needed to think "developmentally" in ways that extend from the "bench side" in the lab to the "curb side" in the community, integrating a developmental perspective into research and clinical practice to achieve health accessibility and equity in pain care for all children across the developmental spectrum.

Review
Orofacial pain and dysfunction in patients with special needs, with a focus on interdisciplinarity.
People with special needs, like those with Down syndrome, Parkinson disease, or dementia, frequently suffer from orofacial pain conditions and dysfunction of the masticatory system. However, the accurate assessment of orofacial pain and dysfunction in such individuals is challenging. ⋯ To accomplish all this, interdisciplinary collaboration between medical doctors and dentists should be promoted in research, education, prevention, and care provision. Therefore, this review focuses specifically on this important topic.

While our understanding of pain is rapidly growing, some areas of pain research are lagging behind. This article discusses two current and inter-related gaps in knowledge that are in need of addressing: first, the connections between "brain" and "body" components of pain; and second, the process of endogenous pain resolution. ⋯ These include comprehensive mapping of the mechanosensory and nociceptive innervation of deep tissues; developing objective, non-invasive measurements to quantify the metabolic, structural and mechanical components of the peripheral tissue environment; integrating our understanding of pain pathophysiology, across whole organs and whole body, as well as across bio-psycho-social domains; and understanding the interplay of nervous system and peripheral tissue mechanisms that promote the endogenous resolution of pain and prevent its acute-to-chronic transition. Current NIH-led efforts in these areas are outlined, including several studies within the NIH HEAL (or Help End Addition Long Term) initiative and the National Center for Complementary and Integrative Health's strategic priorities in whole person research.

"Somehow scientists still pursue the same questions, if now on higher levels of theoretical abstraction rooted in deeper layers of empirical evidence… To paraphrase an old philosophy joke, science is more like it is today than it has ever been. In other words, science remains as challenging as ever to human inquiry. ⋯ In this paper, we will describe how transgenics, transcriptomics, optogenetics, calcium imaging, fMRI, neuroimmunology and in silico drug development have transformed the way we examine the complexity of pain processing. But does it all, as our founders hoped, help people with pain? Are voltage-gated Na channels the new holy grail for analgesic development, is there a pain biomarker, can we completely replace opioids, will proteomic analyses identify novel targets, is there a "pain matrix," and can it be targeted? Do the answers lie in our tangible discoveries, or in the seemingly intangible? Our founders could barely imagine what we know now, yet their questions remain.

Chronic pain is a major global health problem. Untreated pain causes particular suffering in marginalized communities. Most studies investigating chronic pain in sub-Saharan Africa stem from South Africa and Nigeria. ⋯ The body sites most commonly affected among those with chronic pain were knees (37.2%), followed by lower back (33.7%) and head (23.3%). The data for the first time provide insights into the burden of chronic pain among Somali pastoralists and reveal associated risk factors. The results support the planning of locally adapted health interventions for pastoralist-specific pain management considering the effects of chronic pain on pastoralists' daily lives.
