An advanced Mendelian Cannabis breeding program has been developed utilizing chemical markers to maximize the yield of phytocannabinoids and terpenoids with the aim to improve therapeutic efficacy and safety. Cannabis is often divided into several categories based on cannabinoid content. Type I, Δ(9)-tetrahydrocannabinol-predominant, is the prevalent offering in both medical and recreational marketplaces. In recent years, the therapeutic benefits of cannabidiol have been better recognized, leading to the promotion of additional chemovars: Type II, Cannabis that contains both Δ(9)-tetrahydrocannabinol and cannabidiol, and cannabidiol-predominant Type III Cannabis...

BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block has been demonstrated as a useful analgesia technique in lower-abdomen surgeries. We hypothesized that it could be the principal anesthesia technique for end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) catheter (PDC) implantation using the open dissection method. METHODS: This was a single-center, prospective, randomized, and double-blinded study. All eligible patients were randomized into 2 groups: the TAP block group (n = 20) and the local anesthetic infiltration (LAI) group (n = 20)...

Development targets in anaesthetic pharmacology have evolved from minimizing harm caused by unwanted effects through an era in which rapid onset and offset of drug effect were prioritised. Today's anaesthetists have access to a library of effective drugs whose characteristics offer controllable hypnosis, analgesia and paralysis with manageable off-target effects. The availability of these agents at generic prices inhibits commercial interest and this is reflected in the limited number of current anaesthetic drug development projects...

REVIEW
J Lötsch, I Weyer-Menkhoff, I Tegeder
Cannabinoids have a long record of recreational and medical use and become increasingly approved for pain therapy. This development is based on preclinical and human experimental research summarized in this review. Cannabinoid CB1 receptors are widely expressed throughout the nociceptive system. Their activation by endogenous or exogenous cannabinoids modulates the release of neurotransmitters. This is reflected in antinociceptive effects of cannabinoids in preclinical models of inflammatory, cancer and neuropathic pain, and by nociceptive hypersensitivity of cannabinoid receptor-deficient mice...

BACKGROUND: Anesthetic block of the peripheral nerves in the foot and ankle is generally used as anesthesia. The increased use of anesthetic blocks has made this technique an increasingly safe method, and its use has been expanded to postoperative analgesia in foot and ankle surgeries. The objective of this study was to evaluate the analgesia time and pain intensity, using objective scores, after peripheral nerve block in foot and ankle surgeries. METHODS: Patients who underwent surgery by the foot and ankle group of our institution from March 2016 to January 2017 were invited to participate in this prospective, randomized, and blinded study after signing an informed consent form...

Background: In patients with serious illness or trauma, reduction of severe pain is a key therapeutic goal of emergency medical service (EMS) teams. In Germany, only physicians are allowed to use opioid analgesics. In the rural EMS area studied, the mean arrival time for paramedics is 8 minutes, 23 seconds, and for the rescue physician between 10 minutes, 30 seconds and 16 minutes, 59 seconds, depending on EMS site. In cases of parallel callouts, rescue-physician arrival times may be considerably longer...

Calcineurin/NFAT1 signaling pathway plays critical roles in maintaining the homeostasis of articular chondrocytes and in regulating the pathogenesis of osteoarthritis (OA). A few studies demonstrate therapeutic values of ropivacaine (Rop) in OA, but the underlying mechanisms have not been defined. Here, we determined whether Calcineurin/NFAT1 signaling pathway mediates the benefits of Rop to OA. OA rat models were established by a single intra-articular injection of monosodium iodoacetate. The pathophysiology of OA was evaluated by measuring hyperalgesia behavior and the expression of NFAT1, calcineurin, catabolic enzymes in chondrocytes, and chondrogenic markers in affected articular cartilage and primary chondrocyte cultures treated with IL-1β...

OBJECTIVES: The use of etomidate and rocuronium for rapid sequence intubation (RSI) results in a duration of paralysis that exceeds the duration of sedation. The primary objective of this study was to compare the number of analgosedative (AGS) interventions early versus late post-RSI, with this drug combination. The secondary objective was to descriptively assess time to first AGS intervention. METHODS: This was a retrospective cohort study conducted in an academic ED in the United States between January 2015 and June 2016...

BACKGROUND: Hypnotic analgesia is one of the most effective nonpharmacological methods for pain control. Hypnosis and distraction of attention from pain might share similar mechanisms by which brain responses to painful stimulation could be similarly reduced in both states. There is ample evidence for the efficacy of clinical hypnosis as a psychological intervention in the treatment of acute or chronic pain. Results are conflicting, however, with some studies showing an increase, others a reduction, and others still no change in the amplitude of event-related brain potentials during hypnosis as compared to control conditions...

Background/aim: Sex-related differences in response to pain have become a topic of increasing interest. However, sex-related differences in the efficacy of dexamethasone for postoperative analgesia have not been previously addressed. Materials and methods: The study included 196 men and 196 women, aged between 18 and 45 years, who were scheduled for laparoscopic cholecystectomy. The patients were randomly allocated into dexamethasone (M/F: 98/98) and control (normal saline; M/F: 98/98) groups. Patients in the study group received intravenous dexamethasone at 0...

PURPOSE: Studies conducted since 1969 have shown that the release of serotonin (5-HT) in the dorsal horn of the spinal cord contributes to opioid analgesia. In the present study, the participation of the opioidergic system in antinociceptive effect serotonin at the peripheral level was examined. METHODS: The paw pressure test was used with mice (Swiss, males from 35 g) which had increased pain sensitivity by intraplantar injection of PGE2 (2 μg). Serotonin (250 ng), administered locally to the right paw of animals, produces antinociception in this model...

CONTEXT: Sub-Saharan Africa faces an increasing incidence and prevalence of life-limiting and life-threatening conditions. These conditions are associated with a significant burden of pain linked to high morbidity and disability that is poorly assessed and undertreated. Barriers to effective pain management partly relate to lack of access to opioid analgesia and challenges in their administration. OBJECTIVES: To identify country-specific and broader regional barriers to access, as well as the administration of opioids, and generate recommendations for advancing pain management in Southern Africa...

BACKGROUND: Fractures of the proximal femur in elderly patients are a challenge for orthopedics, anesthe-sio-logy and geriatrics. Early mobilization reduces postoperative mortality among these patients. Effective anal-gesia is necessary to achieve this goal. MATERIAL AND METHODS: A retrospective analysis of perioperative medical records of 78. patients undergoing surgical treatment of proximal femur fractures was performed. Group 1 (n=35)consisted of patients who were treated with pharmacologic analgesia only (systemic analgesics) and Group 2 (n=43) involved patients who re-ceived a preoperative fascia iliaca compartment block (FICB) and pharmacologic analgesia...
