The question of hormonal dysregulation in patients with CRPS I in whole was investigated very scantily. There are only a few studies concerning catecholamines, oestrogens and endorphins independently. Other hormones were studied in patients with different other chronic pain conditions. Considering the accumulation of sufficient knowledge about the role of disadaptation processes in CRPS I pathogenesis and the role of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-ovarian systems in the process of adaptation it was logical and consistent to define the role of hormonal dysregulation of these systems in patients with CRPS I. ⋯ This study determined the role of hypothalamic-pituitary-adrenal and hypothalamic-pituitary-ovarian systems in pathogenesis of CRPS I.

Sepsis Pathophysiology, Chronic Critical Illness, and Persistent Inflammation-Immunosuppression and Catabolism Syndrome.
To provide an appraisal of the evolving paradigms in the pathophysiology of sepsis and propose the evolution of a new phenotype of critically ill patients, its potential underlying mechanism, and its implications for the future of sepsis management and research. ⋯ Although newer therapeutic interventions are targeting the inflammatory, the immunosuppressive, and the protein catabolic responses individually, successful treatment of the septic patient with chronic critical illness and persistent inflammation-immunosuppression and catabolism syndrome may require a more complementary approach.

Functional and structural assessment of patients with and without persistent pain after thoracotomy.
Persistent pain is frequent after thoracotomy, with a reported prevalence of up to 60%. It remains unclear why some patients develop pain, whereas others do not. We therefore examined patients with and without pain after thoracotomy to identify pathophysiological contributors to persistent pain. ⋯ Evoked pain is more frequent in patients with pain. Assessment of intradermal nerve density, capsaicin-induced flare response and contact and laser heat-evoked potentials revealed no differences between pain patients and pain-free patients.

Previous work suggests that impairments of cerebrovascular flow or reactivity might be early markers of cerebral amyloid angiopathy (CAA). Hereditary cerebral haemorrhage with amyloidosis-Dutch type (HCHWA-D) is a genetic form of CAA that can be diagnosed before the onset of clinical symptoms by DNA testing. We aimed to investigate whether haemodynamic measures are decreased in presymptomatic and symptomatic HCHWA-D mutation carriers compared with healthy controls. ⋯ USA National Institutes of Health.
