Concussion after a force to the head is called mild traumatic brain injury (mTBI). Approximately 1 in 5 patients with mTBI will develop chronic pain (headache and widespread pain, possibly of central origin) and/or sleep problems (insomnia, disordered breathing, periodic limb movements). However, the predisposing mechanisms for chronic pain in patients with mTBI are unknown. ⋯ Customized approaches are indicated for mTBI, pain, and sleep complaints. Further studies in pediatric, sport, and transportation populations are needed to prevent TBI chronification. Improvements are emerging in biomarker sensitivity and specificity and management strategies for TBI, pain, and sleep comorbidities.

Diagnosis of acute mesenteric ischemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischemia may be treated with urgent intestinal revascularization. ⋯ Intestinal revascularization in patients with arterial occlusive mesenteric ischemia reduces bowel morbidity and mortality. Observational studies report that both endovascular and open vascular therapy options are effective, but endovascular technique may be preferred in these often elderly and fragile patients.

This review presents a general model for the understanding of pain, placebo, and chronification of pain in the framework of cognitive neuroscience. The concept of a computational cost-function underlying the functional imaging responses to placebo manipulations is put forward and demonstrated to be compatible with the placebo literature including data that demonstrate that placebo responses as seen on the behavioural level may be elicited on all levels of the neuroaxis. In the same vein, chronification of pain is discussed as a consequence of brain mechanisms for learning and expectation. ⋯ Women are greatly overrepresented in patients with chronic pain. Hence, both from a general standpoint and from reasons of health equity, it is of essence to advance research and care efforts. Success in these efforts will only be granted with better theoretical concepts of chronic pain mechanisms that maps into the framework of cognitive neuroscience.

ReviewInhaled Antibiotics in Cystic Fibrosis (CF) and Non-CF Bronchiectasis.
Bronchiectasis is a pathological diagnosis describing dilatation of the airways and is characterized by chronic lung sepsis. Bronchiectasis has multiple etiologies, but is usually considered in terms of whether it is due to the genetic disorder cystic fibrosis (CF) or secondary to other causes (non-CF bronchiectasis, NCFB). Inhaled antibiotics are used in bronchiectasis to suppress bacterial pathogens and reduce long-term lung function decline. ⋯ In this article, the use of inhaled antibiotics in CF and NCFB is considered in the light of improved understanding of the lung microbiome and why more tailored therapy may be needed based on molecular identification of the microbial pathogens present. The evidence for the use of currently available inhaled antibiotics and advances in inhaled drug packaging and delivery devices are discussed. Finally, the urgent need for prospective randomized clinical trials in CF and NCFB is highlighted and areas for future research identified.

Development and application of psychophysical test paradigms to assess endogenous pain modulation in healthy controls and in patients yielded large body of data over the last 2 decades. These tests can assist in predicting pain acquisition, in characterizing pain syndromes and related dysfunctions of pain modulation, and in predicting response to treatment. This chapter reviews the development of thought on pain modulation in the clinical setup, focusing on conditioned pain modulation, and update on accumulated data regarding the mechanism, protocols of administration, and applications in the clinic.
