Neuropathic pain still present a major diagnostic and therapeutic challenge despite considerable progress in understanding of its mechanisms and publication of number of studies which assessed the efficacy and safety of drugs used in the symptomatic treatment. In practice, it is diagnosed less frequently than recognised in the epidemiological studies, and(More)
Chronic pain affects approximately 1 in 5 people in Europe, and around half of sufferers receive inadequate pain management. The most common location is the lower back. Pharmacological treatment of this condition is challenging because of the range of causative mechanisms and the difficulty of balancing analgesic efficacy and tolerability. An international(More)
Radiofrequency neurolysis of lumbar medial branch is currently the only proven way to treat patients with chronic lumbar zygapophysial joint pain, however, in some patients it can cause transient postoperative pain due to an inflammation caused by trauma of the electrode insertion and the thermal lesion around the target nerves. The aim of this study was to(More)
The aim of this study was to assess the influence of iv tramadol on opioid requirement in the early postoperative period. The subjects were 90 patients scheduled for colon surgery (hemicolectomy) who received general anesthesia using the (N2O/O2) isoflurane technique. Thirty patients (group I) were administered 100 mg of tramadol iv before induction of(More)
This was a multicenter, non-interventional, post-marketing study that aimed to evaluate the analgesic activity, safety of use, safety profile and adverse drug reactions of transdermal buprenorphine (Transtec 35, 52.5 and 70 μg/h) during the treatment of moderate to severe chronic cancer and non-cancer pain. The study was performed in Poland by 339 doctors.(More)
BACKGROUND Angiogenesis is a basic process that enables neoplasms to thrive. Microvessel density (MVD) evaluation is an accepted parameter for assessing the angiogenesis process within a tumor. The aim of the present study has been to assess the number of microcapillaries in both invasive ductal breast cancer with the presence of metastases in regional(More)
Neuropathic pain may be caused by a variety of lesions or diseases of both the peripheral and central nervous system. The most common and best known syndromes of peripheral neuropathic pain are painful diabetic neuropathy, trigeminal and post-herpetic neuralgia, persistent post-operative and post-traumatic pain, complex regional pain syndrome,(More)
OBJECTIVE To analyze the effect of coadministration of morphine and amantadine on postoperative pain reduction and morphine consumption in patients after elective spine surgery. METHODS In double-blinded study, 60 patients (ASA physical status I-II) were randomized into two groups. Group A was given oral amantadine 50 or 100 mg 1 hour before surgery and(More)
Postoperative pain, arising due to surgical tissue injury, is most frequent type of pain found in clinical practice. In postoperative analgesia opioids still constitute the fundamental form of pain treatment, but the development of neurophysiology and neuropharmacology has allowed for the optimization of postoperative analgesia. Therefore, in order to(More)
Visceral pain is an important therapeutic problem. A number of studies have established that abdominal vagal afferents modulate somatic pain behavior. Although it is not clear if vagal afferents transmit nociceptive information, a change in their activity can increase or decrease nociceptive transmission in visceral pain. Aims of the present study were to(More)
