Our purpose here is to announce results in harmonic analysis related to a large class of hypoelliptic operators on arbitrary simply-connected nilpotent Lie groups. We find the asymptotic development of their fundamental solutions, both locally and at infinity, and study corresponding Riesz transforms and analogues of the Hardy-Littlewood-Sobolev theorem for fractional integration. Details will ...

The Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), Verbal Rating Scale (VRS), and the Faces Pain Scale-Revised (FPS-R) are among the most commonly used measures of pain intensity in clinical and research settings. Although evidence supports their validity as measures of pain intensity, few studies have compared them with respect to the critical validity criteria of responsivity, and...

BACKGROUND AND AIMS Considering the paucity of regional data, this study was designed to investigate the prevalence of post-operative pain and determine if there exists any correlation between the intensity of post-operative pain and patient's level of satisfaction with their pain management after inpatient abdominal surgery at an academic tertiary care government centre. METHODS Pain intensi...

PURPOSE Pain severely impairs health-related quality of life and is a feared symptom among cancer patients. Unfortunately, patients often do not receive optimal care. We wanted to evaluate the quality of cancer pain treatment in Norwegian hospitals. PATIENTS AND METHODS A one-day prevalence study targeting hospitalised cancer patients above 18 years of age was performed. A questionnaire based...

The following case series describes the treatment of neuropathic pain in post-surgical scars, using adipocytes and adipose-derived stem/progenitor cells (ASCs). Two cases are described in which patients underwent lipofilling to treat painful scars after cosmetic surgery. The primary indication for lipofilling was pain reduction and not improved cosmesis. Numeric rating scale (NRS) values were r...

UNLABELLED This study evaluates the construct validity (including sensitivity to change) of the numerical rating scale (NRS) for pain intensity (I) and unpleasantness (U) and participant pain scale preferences in children/adolescents with acute postoperative pain. Eighty-three children aged 8 to 18 years (mean = 13.8, SD = 2.4) completed 3 pain scales including NRS, Verbal Rating Scale (VRS), a...

BACKGROUND Many women consider mammography painful. Existing studies on pain-preventing strategies only mention pain scores reported before and after breast compression. Studying the pain dynamics during the entire compression cycle may provide new insights for effective pain-preventing strategies. METHODS This observational study included 117 women who consented to use a custom turning knob ...

To compare the analgesic efficacy and safety of the sole local anesthetic ropivacaine with the combination of both local anesthetic ropivacaine and opioidergic analgesic sufentanil given epidurally on the labor pain control.After institutional review board approval and patient consent, a total of 500 nulliparas requesting epidural labor analgesia were enrolled and 481 eventually were randomized...
