Pain after stroke: A review.

Pain after stroke (PAS) is a common clinical problem that is both underdiagnosed and undertreated. Yet, it induces depression and cognitive troubles, and impairs quality of life. To provide tools for practitioners, this report describes the most common PAS syndromes, including central post-stroke pain, spasticity and contractures, shoulder pain and complex regional pain syndromes, as well as headache and chondrocalcinosis, along with their risk factors, their prevention and their specific treatments.

[Influence of platelet rich fibrin (PRF) on proliferation of human preadipocytes and tympanic keratinocytes: A new opportunity in facial lipostructure (Coleman's technique) and tympanoplasty?].

Aim: To analyze the effects of PRF (a platelet and immune autologous concentrate) on in vitro proliferation of human keratinocytes and preadipocytes, and to determine if these results may offer an opening on new clinical investigations, particularly in the improvement of tympanoplasties and facial lipostructures (Coleman's technique).

Materials And Methods: Human tympanic keratinocytes and preadipocytes are collected and cultured using the explant technique. 4 series of each type of cells are cultivated either in normal condition (control group) or with PRF (test group).

Fear-avoidance beliefs about back pain in patients with subacute low back pain.

The fear-avoidance beliefs of patients with subacute low back pain (LBP) considered at risk for chronic disabling LBP are not well known. The objectives of this cross-sectional descriptive survey, conducted in secondary care practice, were to assess fear-avoidance beliefs about back pain in patients with subacute LBP and to seek an association between physician or patient characteristics and level of fear-avoidance beliefs. A total of 286 rheumatologists completed a self-administered questionnaire assessing physicians' demographic, professional data, personal history of back pain, and back pain fear-avoidance beliefs (on the Fear-Avoidance Belief Questionnaire [FABQ]) and 443 patients with sLBP completed one on pain, perceived handicap and disability (Quebec Back Pain Disability Scale), anxiety and depression (Hospital Anxiety Depression questionnaire), and back pain beliefs (FABQ).

[Role of paracetamol in the acute pain management].

Paracetamol (acetaminophen) has been shown to be an effective analgesic for the treatment of moderate pain where it is chiefly indicated, as shown in placebo-controlled studies in the perioperative setting and other acute pain states. In addition, an opioid-sparing effect has been demonstrated. No clinically relevant adverse effects are usually apparent with recommended doses.

[Headaches caused by abuse of symptomatic anti-migraine and analgesic treatment].

These daily or near-daily headaches result from the chronic overuse of all immediate relief antimigraine drugs: ergotamine, analgesics, and/or more recently triptans. Like for much chronic daily headaches, the International Headache Society diagnostic criteria for drug abuse headaches are difficult to apply. Generally, patients confuse primary headaches (usually migraines) with interparoxysmal tension-type headaches called "rebound headaches".

[Multidisciplinary treatment of neurologic pain and indications for antalgic surgery].

We present our multidisciplinary approach systematically adopted for patients with resistant pain. All the anatomic, pathophysiological, clinical, radiographical, electrophysiological and psychological aspects of pain should be considered before deciding on treatment indication. These principles are illustrated by a description of different available medical and surgical techniques for the treatment of paraplegic pain.

[The use of opioids by the regional route in the treatment of pain].

The decision to administer regional opioids either by an epidural or a subarachnoid route (intrathecal or intraventricular) necessitates a prior multiparametric analysis. When opiate therapy is definitively indicated regional opiate administration usually relays an insufficient or poorly tolerated oral route. The epidural route seems to be the best way for transient indications; the choice of the opioid drug then depends on the local or disseminated character of pain.

Labor pain assessment: validity of a behavioral index.

There is a need for adequate and convenient measures for assessing obstetric pain. The present investigation was designed to develop a non-verbal objective measurement of labor pain based on the continuous observation of behavior. Validity and sensitivity of the instrument designed to assess pain throughout labor using standardized observational ratings were tested on a sample of 100 primiparae who were asked periodically to rate pain on a 5-point numerical scale.
