Cocaine related hallunications

var pageTracker = _gat._getTracker("UA-3639768-12"); pageTracker._initData(); pageTracker._trackPageview(); Classically is the sensation of animal, bugs or insects moving under the skin (cocaine bugs or parasitosis). Other purely visual hallucinations that can occur include "snow lights" or the sensation of sunlight reflecting off snow crystals. Vibrating and pulsating geometric shapes, polyopia, and dysmorphia occur and resemble visual aura. Olfactory, tactile and gustatory hallucinations may occur. Photophobia, halos around lights, and gtrouble focusing may be due instead to pupillary mydriasis due to increased sympathetic tone.

This study used a comprehensive battery of laboratory tasks to assess peripheral fiber function (cool/warm detection thresholds), pain sensitivity (eg, thresholds/tolerances), central sensitization (eg, temporal summation), and pain inhibition (conditioned pain modulation) in healthy, pain-free adults (N = 155 NAs, N = 150 non-Hispanic Whites [NHWs]). Multiple pain stimulus modalities were used (eg, cold, heat, pressure, ischemic, and electric), and subjective (eg, pain ratings and pain tolerance) and physiological (eg, nociceptive flexion reflex) outcomes were measured. There were no group differences on any measure, exce...

This study aims to test the hypothesis that induced spinal sensitization could be more pronounced in patients affected by high-frequency migraine (HF-MIG) with respect to low-frequency migraine (LF-MIG). We enrolled 28 patients with LF-MIG (1-5 migraine days/month), 19 patients with HF-MIG (6-14 migraine days/month), and 21 healthy controls (HCs). Spinal sensitization was evaluated with the neurophysiological recording of the temporal summation threshold (TST) of the nociceptive withdrawal reflex at the lower limb. Temporal summation threshold was recorded at baseline and 30, 60, and 120 minutes after NTG administration (0...

Low levels of catechol-O-methyltransferase (COMT), an enzyme that metabolizes catecholamines, and stress, which potentiates catecholamine release from sympathetic nerves, are fundamental to chronic functional pain syndromes and comorbid depression, which predominantly affect females. Here, we sought to examine the independent and joint contributions of low COMT and stress to chronic functional pain and depression at the behavioral and molecular level. Male and female C57BL/6 mice received sustained systemic delivery of the COMT inhibitor OR486 over 14 days and underwent a swim stress paradigm on days 8 to 10. Pain and depr...

(CNN) — Marie Antoinette’s hair suddenly turned white before the ill-fated French queen was taken to the guillotine to have her head chopped off, according to some historical accounts. More modern reports refer to hair turning prematurely white in survivors of bomb attacks during World War II, while an Australian airline pilot saw his hair go gray in the months after landing a plane following a failure of all four engines in the early 1980s. While there’s been plenty of anecdotal evidence suggesting premature graying can be caused by extreme stress — whether this is true and how this happens isn&rsq...

When Ya-Chieh Hsu, professor of stem cell and regenerative biology at Harvard University and the Harvard Stem Cell Institute, wanted to figure out exactly what makes hair turn grey, she started with an obvious, albeit anecdotal, culprit: stress. There are well-known historical examples of the connection between stress and hair greying—Marie Antoinette’s coif reportedly blanched after she was captured during the French Revolution—and studies have even linked stress in animals to greying hair. But for the first time, Hsu and her colleagues figured out the biological reason why stress saps the pigment out of...

This study was conducted among healthy adolescents to assess the effects of a yoga breathing practice (Bhramari pranayama, Bhr.P) towards cardiac autonomic function using heart rate variability (HRV) parameters.MethodsOf the 730 eligible subjects screened, 520 healthy adolescents who met the inclusion and exclusion criteria were randomly assigned to either yoga breathing group (n = 260) or control group (n = 260). The yoga breathing group practiced Bhr.P. five days a week for a duration of six months while the control group continued with their daily routine without any intervention. Outcome mea...

Laryngopharyngeal reflux and atypical manifestations of gastroesophageal reflux disease have a high economic and social burden in the United States. There is increasing research supporting the reflex theory and hypersensitivity syndrome underlying this disease pathophysiology. Novel diagnostic biomarkers have gained more traction in the search for a more reliable diagnostic tool, but further research is needed. Current standard-of-care treatment relies on proton pump inhibitor therapy. Antireflux surgery is usually not recommended. Neuromodulators and treatments targeting specific neuronal receptors are discussed. A diagno...

The human and dog have sinus arrhythmia; however, the beat-to-beat interval changes were hypothesized to be different. Geometric analyses (R–R interval tachograms, dynamic Poincaré plots) to examine rate changes on a beat-to-beat basis were analyzed along with time and frequency domain heart rate variability from 40 human and 130 canine 24-h electrocardiographic recordings. Humans had bell-shaped beat-interval distributions, narrow interval bands across time with continuous interval change and linear changes in rate. In contrast, dogs had skewed non-singular beat distributions, wide interval bands {despite fas...

Scapulothoracic arthrodesis (STA) has been proposed for the treatment of painful scapular winging in patients with facioscapulohumeral muscular dystrophy (FSHD). However, the rate of osseous fusion is variable, and there is a theoretical risk of reduced respiratory function after bilateral STA.
