Adaptations in somatosensory function characterize several chronic pain conditions, including nonspecific neck pain (NNP). Early signs of central sensitization (CS) contribute to pain chronification and poor treatment responses after conditions such as whiplash injury and low back pain. Despite this well-established association, the prevalence of CS in patients with acute NNP, and accordingly, the potential impact of this association, is still unclear. Therefore, this study aimed to investigate whether changes in somatosensory function occur during the acute phase of NNP. ⋯ Changes in somatosensory function occur already in acute NNP. Local mechanical hyperalgesia demonstrated peripheral sensitization, while enhanced pain facilitation, impaired conditioned pain modulation, and self-reported symptoms of CS suggest adaptations in pain processing already early in the stage of NNP.

ReviewRegional anesthesia in the emergency department outside the operating theatre.
Moderate to severe pain is common and remains a significant problem in the emergency department and regional anesthesia provides optimal and safe pain relief. This review aims to discuss the benefits, indications of the most common ultrasound-guided regional anesthesia techniques that can be provided by clinicians in the emergency department as part of multimodal analgesia. We will also comment on the education and training for effective and safe ultrasound-guided regional anesthesia in the emergency department. ⋯ Emergency physicians are perfectly placed to utilize the advantages of ultrasound-guided regional anesthesia. Various techniques can now be employed to cover most of the painful injuries presenting to the emergency department, thus modifying the morbidity and outcomes of emergency patients. Some of the new techniques require minimal training, provide safe and effective pain relief with low risk of complications. Ultrasound-guided regional anesthetic techniques should form an integral part of the curriculum of emergency department physicians.

In the past 20 years of the Global War on Terror, the US has seen substantial improvements in its system of medical delivery in combat. However, throughout that conflict, enemy forces did not have parity with the weaponry, capability, or personnel of the US and allied forces. War against countries like China and Russia, who are considered near-peer adversaries in terms of capabilities, will challenge battlefield medical care in many different ways. ⋯ The team has extensive experience in medicine, surgery, austere environments, conflict zones, and building partner nation capacities. This article compares and contrasts the healthcare systems of this war against the systems used during the Global War on Terror. The lessons learned here could help the US anticipate challenges and successfully plan for the provision of medical care in a future conflict against an adversary with capabilities close to its own.

To better understand the established associations between hypocalcaemia and clinical outcomes, we synopsize the mechanisms involved in hypocalcaemia in the critically ill. We also provide an overview of the current evidence on managing hypocalcaemia in critical illness. ⋯ Hypocalcaemia is common in critically ill patients. Direct evidence that calcium supplementation improves their outcomes is lacking, and there is even some indication that it may be detrimental. Prospective studies are required to elucidate the risks and benefits, and the pathophysiological mechanisms involved.

Drug resistance is estimated to affect about a third of individuals with epilepsy, but its prevalence differs in relation to the epilepsy syndrome, the cause of epilepsy, and other factors such as age of seizure onset and presence of associated neurological deficits. Although drug-resistant epilepsy is not synonymous with unresponsiveness to any drug treatment, the probability of achieving seizure freedom on a newly tried medication decreases with increasing number of previously failed treatments. ⋯ Substantial evidence indicates that a delay in identifying an effective treatment can adversely affect ultimate outcome and carry an increased risk of cognitive disability, other comorbidities, and premature mortality. Research on mechanisms of drug resistance and novel therapeutics is progressing rapidly, and potentially improved treatments, including those targeting disease modification, are on the horizon.
