The study aim was to describe migraine incidence over the ten-year periods, 2000-2009 and 2010-2019, in individuals aged 10-79 years in primary healthcare centre (PHCC) Sólvangur and Fjörður, Hafnarfirði. Another aim was to estimate migraine prevalence in primary care clinics in the capital area of Iceland over the period 2010-2019 and describe prescriptions for migraine specific drugs and other drugs used for migraine.

Back pain is a common health complaint that contributes globally to medical burden and costs, particularly in elderly populations. Nuclear medicine techniques using PET tracers offer diagnostic information about various spine disorders, including malignant, degenerative, inflammatory, and infectious diseases. Herein, the authors briefly review applications of PET in the evaluation of spine disorders in elderly patients.

Advancing age significantly affects the structural and functional characteristics of organs and tissues, including the peripheral nervous system (PNS) and musculoskeletal system. PET molecular imaging systems offer the ability to assess the metabolic and quantitative effects due to nerve and muscle injuries, which has the potential to impact clinical management of aged subjects. Here, we aim to describe some features of molecular imaging PET systems using different tracers and methods of imaging in musculoskeletal disorders and peripheral neuropathies commonly seen in elderly patients.

Chronic pain is undertreated in people with Alzheimer's disease (AD) and better understanding of the underlying mechanisms of chronic pain in this neurodegenerative disease is essential. Neuropathic pain and AD share a significant involvement of the peripheral immune system. Therefore, we examined the development of nerve injury-induced allodynia in TASTPM (APPsweXPS1.M146V) mice and assessed monocytes/macrophages at injury site. TASTPM developed partial allodynia compared to WT at days 7, 14 and 21 days after injury, and showed complete allodynia only after treatment with naloxone methiodide, a peripheralized opioid receptor antagonist. Since macrophages are one of the sources of endogenous opioids in the periphery, we examined macrophage infiltration at injury site and observed that CD206/MHCII cells were more numerous in TASTPM than WT. Accordingly, circulating TASTPM Ly6C (classical) monocytes, which are pro-inflammatory and infiltrate at the site of injury, were less abundant than in WT. In experiments, TASTPM bone marrow-derived macrophages showed efficient phagocytosis of myelin extracts containing amyloid precursor protein, acquired CD206/MHCII phenotype, upregulated mRNA expression of proenkephalin () and accumulated enkephalins in culture media. These data suggest that in TASTPM nerve-injured mice, infiltrating macrophages which derive from circulating monocytes and may contain amyloid fragments, acquire M2-like phenotype after myelin engulfment, and release enkephalins which are likely to inhibit nociceptive neuron activity via activation of opioid receptors.

Obstructive sleep apnea (OSA) is characterized by repetitive episodes of complete or partial upper airway obstruction during sleep, with a worldwide estimate of 936 million sufferers. Treatments of OSA include continuous positive airway pressure (CPAP), weight loss, positional therapy, oral appliances, positive upper airway pressure, oro-maxillofacial surgery, hypoglossal nerve stimulation, and bariatric surgery, and others, with CPAP being the most commonly prescribed treatment. In this review, the neurologic conditions of stroke, cognitive decline, epilepsy, and migraines will be discussed as they relate to OSA. Additionally, the literature regarding improvement in these conditions following treatment with CPAP will be explored.

Obesity is a worldwide epidemic and is associated with an increased risk of hypertension, diabetes, and obstructive sleep apnea. Pregnant patients with obesity experience a higher risk of maternal and fetal complications. Anesthesia also poses higher risks for obese parturients and may be more technically challenging due to body habitus. Safe anesthesia practice for these patients must take into consideration the unique challenges associated with the combination of pregnancy and obesity.

Appropriate perioperative pain control is essential to aid in patients' recovery after surgery; however, acute postsurgical pain remains poorly treated and there continues to be an overreliance on opiates. Perioperative pain control starts in the operating room, and opiate-free anesthesia (OFA), where no opiates are used intraoperatively, has been proposed as a feasible strategy to further minimize opiates in the perioperative period. In this article, we address the potential benefits and shortcomings of OFA, while exploring tools available to accomplish multimodal anesthesia and ideally OFA, and the evidence behind the techniques proposed.

Although clinical improvement after stenting for symptomatic iliofemoral venous obstruction has been demonstrated in multiple large studies, a small proportion of patients will experience persistent quality of life-impairing symptoms. Swelling in such a setting represents the concomitant presence of lymphedema and will respond to treatment directed at the lymphedema. In contrast, persistent pain likely arises from venous hypertension in the lower leg, leading to the development of chronic compartment syndrome. Evaluation of intracompartmental pressures in such patients can help confirm the diagnosis, and fasciectomy combined with fasciotomy will treat the issue. In the present series, we evaluated six patients (six limbs) who had undergone fasciectomy combined with fasciotomy and their outcomes.
