This review article explores the need for specialized pain care for children and adolescents and provides some historical context for our current knowledge base and clinical practice. ⋯ Awareness of children's pain has increased dramatically over the past three decades, and Canadians have performed a leadership role in much of the research. Specific multidisciplinary teams are a more recent phenomenon, but they are shown to be more effective and probably more cost effective than traditional treatment models. Important gaps in availability of resources to manage these patients remain.

This is a selective narrative review of the latest information about the epidemiology, impact, and prevention of chronic post-surgical pain (CPSP), intended primarily for those without a special interest in pain medicine. ⋯ Reduction of CPSP is a worthy long-term outcome for anesthesia providers to consider as they plan the perioperative care of their patients. More evidence is needed about the effect of currently used analgesics and other perioperative techniques on CPSP.

Jordanian cancer patients' information needs and information-seeking behaviour: a descriptive study.
Cancer diagnosis can leave patients with uncertainty and anxiety that can be reduced by providing timely information and effective communication. Despite information provision being highly important in improving the quality of provided care, no study had been conducted to assess the information needs of Jordanian cancer patients. ⋯ Many factors may cause variations in patients' information-seeking behaviour. Therefore, a notational policy for information provision is needed to satisfy different patients' information needs. Healthcare providers should be aware that cancer patients' will continue to need information at all stages.

The transition from acute to chronic pain: understanding how different biological systems interact.
Although pain is an adaptive sensory experience necessary to prevent further bodily harm, the transition from acute to chronic pain is not adaptive and results in the development of a chronic clinical condition. How this transition occurs has been the focus of intense study for some time. The focus of the current review is on changes in neuronal plasticity as well as the role of immune cells and glia in the development of chronic pain from acute tissue injury and pain. ⋯ A better understanding of how chronic pain develops at a mechanistic level can aid clinicians in treating their patients by showing how the underlying biology of chronic pain contributes to the clinical manifestations of pain. A thorough understanding of how chronic pain develops may also help identify new targets for future analgesic drugs.

Regulation of Hypoxia-Induced Pulmonary Hypertension by Vascular Smooth Muscle HIF-1alpha.
Chronic hypoxia induces pulmonary vascular remodeling, pulmonary hypertension, and right ventricular hypertrophy. At present, little is known about mechanisms driving these responses. Hypoxia-inducible factor-1α (HIF-1α) is a master regulator of transcription in hypoxic cells, up-regulating genes involved in energy metabolism, proliferation, and extracellular matrix reorganization. Systemic loss of a single HIF-1α allele has been shown to attenuate hypoxic pulmonary hypertension, but the cells contributing to this response have not been identified. ⋯ These results indicate that HIF-1α in smooth muscle contributes to pulmonary vascular remodeling and pulmonary hypertension in chronic hypoxia. However, loss of HIF-1 function in smooth muscle does not affect hypoxic cardiac remodeling, suggesting that the cardiac hypertrophy response is not directly coupled to the increase in pulmonary artery pressure.
