Neuropathic pain affects millions of people causing disability and impairing quality of life. Commonly used analgesics are generally characterized by limited therapeutic outcomes. The serotonin 5-HT1A receptor and the α2 adrenergic receptors are involved in central nociceptive mechanisms with a pivotal role in the inhibitory descending pain pathway. Since their stimulation may modulate the nervous signaling altered by neuropathies, the purpose of the present research is the study of the combined activation of 5-HT1A and α2 receptors by rationally designed imidazoline ligands ((S)-1 and 2-5) in a rat model of neuropathic pain (chronic constriction injury - CCI)...

BACKGROUND: Pain intensity ratings and opioid consumption (OC) are ubiquitous indicators of pain in postoperative trials of the efficacy of interventional procedures. Unfortunately, consensus on the appropriate statistical handling of these outcomes has not been reached. The aim of this article was, therefore, to reexamine original data obtained from a postoperative analgesic drug trial, applying a collection of standard statistical methods in analgesic outcome assessments. Furthermore, a modified integrated assessment method of these outcomes was evaluated...

AIMS: Extensive evidence supports a role for voltage-gated calcium channels (VGCC) and TRPV1 receptors in pain transmission and modulation. We investigated the profile of analgesic interaction between Phα1β toxin (a VGCC blocker) and SB366791 (selective TRPV1 antagonist) in a model of acute pain induced by capsaicin. Changes in body temperature induced by combination regimens were also evaluated. MAIN METHODS: Isobolographic approach with a fixed dose-ratio of combined drugs was used to determine whether antinociceptive interaction of Phα1β and SB366791 are subadditive, additive or synergic...

The goal of the experimental design was to assess the cutaneous analgesic effect of mexiletine by co-injection with clonidine. The effect of nociceptive block was evaluated according to the inhibition of the cutaneous trunci muscle reflex (CTMR) in response to skin pinpricks in rats. The dose-related analgesic effect of mexiletine alone or mexiletine co-administrated with clonidine was constructed after subcutaneous injection. Subcutaneous injections of mexiletine elicited dose-related cutaneous analgesia. Compared with mexiletine (1...

This paper outlines a treatment protocol to run alongside of standard current treatment of glioblastoma- resection, temozolomide and radiation. The epithelial to mesenchymal transition (EMT) inhibiting sextet, EIS Regimen, uses the ancillary attributes of six older medicines to impede EMT during glioblastoma. EMT is an actively motile, therapy-resisting, low proliferation, transient state that is an integral feature of cancers' lethality generally and of glioblastoma specifically. It is believed to be during the EMT state that glioblastoma's centrifugal migration occurs...

Acupuncture is an alternative treatment for wide spectrum chronic pain. However, its validity remains controversial due to the disputed efficacy assessed in various clinical studies. Moreover, variability amongst individuals complicates the predictability of outcome, which impedes the integration of acupuncture into mainstream pain management programs. In light of our previous finding that the analgesic effect of acupuncture is mediated by adenosine A1 receptor activation at the acupuncture point, we here report that in acute and chronic animal pain models, oral intake of caffeine, a potent adenosine receptor antagonist, interferes with acupuncture analgesia, even at a low dose...

BACKGROUND: Shoulder pain and pain in the upper abdomen are common complaints after laparoscopy, sometimes surpassing the pain at incision sites. The incidence of shoulder pain ranges from 35 to 80%. Post-laparoscopic pain is caused by retention of carbon dioxide in the abdomen, which irritates the phrenic nerve and diaphragm, causing referred pain in the shoulder and in the upper abdomen. A promising strategy to reduce this post-laparoscopic pain is the pulmonary recruitment maneuver, which indirectly increases intraperitoneal pressure and thereby facilitates removal of residual carbon dioxide...

Resveratrol has been widely studied in terms of it's potential to slow the progression of many diseases. But little is known about the mechanism of action in neuropathic pain. Neuropathic pain is the main type of chronic pain associated with tissue injury. Calcium channels and calcium/caffeine-sensitive pools are associated with analgesic pathway involving neuropathic pain. Our previous study suggested that the antinociceptive effect of resveratrol was involved in Ca(2+)/calmodulin-dependent signaling in the spinal cord of mice...

Evidence to support the argument that general anesthesia (GA) with paravertebral block (PVB) provides better pain relief for mastectomy patients than GA alone is contradictory. The aim of this study was to explore pain and analgesia after mastectomy with or without PVB during acute inpatient recovery. A retrospective study was conducted in a single hospital providing specialist cancer services in metropolitan Melbourne, Australia. We explored pain and concomitant analgesic administration in 80 consecutive women recovering from mastectomy who underwent GA with (n = 40) or without (n = 40) PVB...

INTRODUCTION: Transumbilical laparoscopic-assisted appendectomy (TULAA) is the technique of choice for all types of appendicitis in our Department. It combines the advantages of laparoscopy (global vision and minimally invasion) and open surgery (lower cost). The objective was to assess the results of our TULAA series and compare them to the results of standard laparoscopic appendectomies (SLA) performed during the same period. METHODS: Retrospective review of total appendectomies performed since TULAA introduction (September 2003 to December 2015) with statistic analysis of the results...

BACKGROUND: Neuropathic pain (NP) (including painful diabetic neuropathy, postherpetic neuralgia, etc) affects approximately 7% to 8% of the population and is associated with a devastating symptom burden as well as a profound economic impact for patients, their families, and the health care system. Current therapies have limited efficacy and dose-limiting adverse effects (AEs). Rational combination therapy with carefully selected NP drugs has shown potential for measurable improvements in pain relief, quality of life, and health care use...
