The stigma of low opioid prescription in the hospitalized multimorbid elderly in Italy.

2015

The primary aim of this study was to evaluate the prevalence of opioid prescriptions in hospitalized geriatric patients. Other aims were to evaluate factors associated with opioid prescription, and whether or not there was consistency between the presence of pain and prescription. Opioid prescriptions were gathered from the REgistro POliterapie Societa` Italiana di Medicina Interna (REPOSI) data for the years 2008, 2010 and 2012. 1,380 in-patients, 65+ years old, were enrolled in the first registry run, 1,332 in the second and 1,340 in the third. The prevalence of opioid prescription was calculated at hospital admission and discharge. In the third run of the registry, the degree of pain was…

Serotoninergic innervation of nonprincipal cells in the cerebral cortex of the lizard Podarcis hispanica.

2004

The mechanism of serotoninergic transmission in the neo- and archicortex of mammals kis complex, including both synaptic and nonsynaptic components, direct actions on principal cells, and indirect effects mediated by GABAergic interneurons. Here we studied the termination pattern and synaptic organization of the serotoninergic afferents in the cerebral cortex of the lizard, Podarcis hispanica, which is considered to correspond in part to the mammalian hippocampal formation, with the aim of unraveling basic, phylogenetically preserved rules in the connectivity of this pathway. We demonstrate that serotoninergic afferents, visualized by immunostaining for serotonin itself, establish multiple …

Human umbilical cord expresses several vasoactive peptides involved in the local regulation of vascular tone: protein and gene expression of Orphanin…

2011

Full-term human umbilical cord contains three blood vessels: two arteries coiled around a vein and surrounded by Wharton’s jelly, a mucous tissue with few mesenchymal stromal cells and abundant extracellular matrix. Umbilical vessels lack innervations, thus endothelial cells must play a role in the control of blood flow. The aim of this study was to investigate in human umbilical cord the expression of five peptides that could be involved in the regulation of vascular tone: Orphanin FQ, Oxytocin, Atrial Natriuretic Peptide (ANP), endothelial Nitric Oxide Synthase (eNOS) and inducible Nitric Oxide Synthase (iNOS). The expression of these molecules in full-term human umbilical cord …

Immunohistochemical and Biomolecular Identification of Orphanin FQ, eNOS, Atrial natriuretic Factor and Oxytocin in Rat Seminal Vesicles

2009

In previous studies performed on rodents, we detected the presence of adreno-cholinergic and peptidergic innervation in seminal vesicles and other organs of the male genital system, such as prostate and ductus deferens, in which we also investigated the expression of NOS and NADPH-diaphorase. During the present project we focused our attention on the expression of some peptides involved in local control of smooth muscle relaxation, contractility, vasodilatation and control of blood flow in rat seminal vesicles. We investigated, through immunohistochemistry and RT-PCR, the presence of four peptides: orphanin, eNOS, ANF and oxytocin. Immunohistochemistry was used to detect the presence of the…

Fentanyl and sufentanyl in fast track anaesthesia for major intra-abdominal surgery

2012

Background and aim: Major intra-abdominal surgery is estimated to have high costs annually in Italy. In an attempt to decrease surgery costs and improve outcome for patients, fast-track programs have become popular. This is especially due both to the improvement of surgery and to the new anesthetic agents (regarding pharmacokinetic and pharmacodynamic) resulting in better care for patients. The aim of this study was to evaluate two different anesthetic protocols in patients undergoing scheduled anesthesia including the combination of two different opioids (fentanyl or sufentanil) with the same hypnotic and muscle relaxant. Material and Methods: 40 patients, with an American Society of Anest…

Pain killer without a high

2005

THC acts as a pain reliever in part by engaging a receptor in peripheral tissues, CB2. But exactly where CB2 is and how it operates has been unclear. A new study shows that cannabinoids, acting through CB2 on skin cells, stimulate the local release of endogenous opioids.

Effects of preemptive analgesia with intravenous acetaminophen on postoperative pain relief in patients undergoing third molar surgery: a prospective…

2020

Background The efficacy of preemptive analgesia in managing postoperative pain remains controversial. The aim of this study was to compare the efficacy of intravenous (IV) acetaminophen administered before or immediately after the surgical extraction of an impacted mandibular third molar. Material and Methods This prospective randomized clinical trial included 120 patients. The patients were assigned to one of three groups: the preoperative-treatment group (pre-group), which received 1000 mg of IV acetaminophen 20 min before surgery; the postoperative-treatment group (post-group), which received 1000 mg of IV acetaminophen after surgery; the no-treatment group (control-group), which did not…

Analgesic Effect of Intravenous Ketamine in Cancer Patients on Morphine Therapy

2000

Pain not responsive to morphine is often problematic. Animal and clinical studies have suggested that N-methyl-D-aspartate (NMDA) antagonists, such as ketamine, may be effective in improving opioid analgesia in difficult pain syndromes, such as neuropathic pain. A slow bolus of subhypnotic doses of ketamine (0.25 mg/kg or 0.50 mg/kg) was given to 10 cancer patients whose pain was unrelieved by morphine in a randomized, double-blind, crossover, double-dose study. Pain intensity on a 0 to 10 numerical scale; nausea and vomiting, drowsiness, confusion, and dry mouth, using a scale from 0 to 3 (not at all, slight, a lot, awful); Mini-Mental State Examination (MMSE) (0-30); and arterial pressure…

Rapid onset opioids for breakthrough pain: Titrating or not titrating, this is the question!

2011

Abstract Breakthrough cancer pain (BTcP) has been defined as a transitory increase in pain intensity that occurs either spontaneously, or in relation to a specific predictable or unpredictable trigger, despite relatively stable and adequately controlled background pain. Traditional dosing recommendations for BTcP have suggested that the effective dose of oral opioids should be a percentage of a patient’s total daily opioid dose. In the last years a number of new formulations that deliver fentanyl directly through mucous membranes have been developed in an effort to provide a more rapid onset of effect (rapid onset opioids, ROOs). Recent recommendations suggest that the dose of ROOs for BTcP…
