Breakthrough Cancer Pain: Preliminary Data of The Italian Oncologic Pain Multisetting Multicentric Survey (IOPS-MS).

Introduction: An ongoing national multicenter survey [Italian Oncologic Pain multiSetting Multicentric Survey (IOPS-MS)] is evaluating the characteristics of breakthrough cancer pain (BTP) in different clinical settings. Preliminary data from the first 1500 cancer patients with BTP enrolled in this study are presented here.

Methods: Thirty-two clinical centers are involved in the survey.

Safety and efficacy of citrate anti-coagulation continuous renal replacement therapies in post-cardiac surgery patients with liver dysfunction.

The study's aim was to examine safety and efficiency of citrate anticoagulated continuous renal replacement therapies (CRRT) in cardiac surgery patients with acute kidney injury and associated liver dysfunction. The study was conducted on critical ICU patients, hospitalized after cardiac surgery, who developed renal and liver acute failures due to low-flow syndrome. CRRT in continuous veno-venous hemodiafiltration with regional citrate anticoagulation (RCA) was prescribed to address renal failure and avoid bleeding-risk.

Italian Oncological Pain Survey (IOPS): a multicentre Italian study of breakthrough pain performed in different settings.

Objective: A survey of breakthrough pain (BTP) was performed in five palliative care units (PCU), seven oncology departments (ONC), and nine pain clinics (OPC).

Methods: A standard algorithm was used to confirm the diagnosis of BTP of patients refereed to different settings.

Results: 1,412 evaluable cancer patients were enrolled.

One-year follow-up of patients with long-lasting post-herpetic neuralgia.

Background: Recent information on epidemiology and management of post-herpetic neuralgia (PHN), a painful complication of zoster, is scarce.

Methods: This study was conducted at the Pain Clinic of the Policlinico Tor Vergata, Rome, Italy, on eighty-five immunocompetent patients with a clinical diagnosis of PHN. At enrollment (time 0, T0), the patients were interviewed by physicians to obtain demographic data and information about their zoster clinical history and underwent a blood test for VZV-DNA research.

Feasibility of frequency-modulated wireless transmission for a multi-purpose MEMS-based accelerometer.

Recent advances in the Micro Electro-Mechanical System (MEMS) technology have made wireless MEMS accelerometers an attractive tool for Structural Health Monitoring (SHM) of civil engineering structures. To date, sensors' low sensitivity and accuracy--especially at very low frequencies--have imposed serious limitations for their application in monitoring large-sized structures. Conventionally, the MEMS sensor's analog signals are converted to digital signals before radio-frequency (RF) wireless transmission.

Breakthrough pain in patients with controlled or uncontrolled basal pain: an observational study.

Background: Breakthrough pain (BTP) is traditionally defined as a pain exacerbation in patients with chronic controlled pain. However, this definition has recently been challenged.

Objectives: To evaluate the prevalence of unsatisfactory control in patients with chronic cancer pain, and investigate the frequency and intensity of BTP episodes.

Long-term efficacy of OROS® hydromorphone combined with pregabalin for chronic non-cancer neuropathic pain.

Background And Objectives: Treatment for chronic non-cancer neuropathic pain can be complicated by side effects and drug interactions. Combining opioid analgesics and calcium channel modulators may overcome these and improve efficacy. The objective of the present study was to evaluate the efficacy and safety of OROS® hydromorphone combined with pregabalin in patients with chronic non-cancer neuropathic pain.

Beyond the traditional definition of breakthrough pain: an observational study.

Introduction: Breakthrough pain (BTP) is traditionally defined as a transitory pain flare in opioid-treated patients with chronic background pain. This definition has, however, been challenged in recent years. This study aimed to analyze BTP prevalence in different pain conditions.

Prolonged-release oxycodone/naloxone in nonmalignant pain: single-center study in patients with constipation.

Introduction: Opioid treatment for chronic malignant and nonmalignant pain of moderateto-severe intensity is associated with bowel dysfunction leading to constipation; this often requires opioid dose reduction or interruption. Combination opioid agonist/antagonist therapy can restore normal bowel function. A prolonged-released (PR) fixed-dose combination of oxycodone and naloxone has been developed and efficacy has been demonstrated in phase 3 clinical trials.

Palmitoylethanolamide in the treatment of chronic pain caused by different etiopathogenesis.

Objective: To assess the efficacy and safety of palmitoylethanolamide (PEA), an endogenous fatty acid amide belonging to the N-acylethanolamines family, in reducing pain severity in patients with pain associated to different pathological conditions.

Methods: This was an observational study conducted on 610 patients who were unable to effectively control chronic pain with standard therapies. PEA (600 mg) was administered twice daily for 3 weeks followed by single daily dosing for 4 weeks, in addition to standard analgesic therapies or as single therapy.

Role of mesotherapy in musculoskeletal pain: opinions from the italian society of mesotherapy.

Mesotherapy is the injection of active substances into the surface layer of the skin. This method allows a slower spread, higher levels, and longer lasting effects of drugs in the tissues underlying the site of injection (skin, muscle, and joint) compared with those following intramuscular injection. This technique is useful when a local pharmacological effect is required and relatively high doses of drug in the systemic circulation are not.

Breakthrough pain in patients referred to pain clinics: the Italian pain network retrospective study.

Introduction: Despite breakthrough pain (BTP) being one of the most severe forms of pain, there are no definitive data on its prevalence.

Methods: The authors performed a retrospective survey of the prevalence of BTP in consecutive patients in four Italian pain clinics, subsequent to application of an Italian law mandating detailed clinical records on pain characteristics, treatment, and results. Mean pain intensity was assessed with a numerical rating scale from 0 to 10.

Management of opioid-induced constipation in cancer patients: focus on methylnaltrexone.

Opioids are one of the most widely used therapies for the palliative treatment of cancer pain; however, despite their proven analgesic efficacy, they are associated with several adverse effects. Associated with psychological distress and multiple concomitant clinical concerns, constipation is the most commonly occurring adverse effect of chronic opioid therapy in cancer patients. Whilst prophylaxis remains the first-line management option, methylnaltrexone is a recommended treatment option for opioid-related constipation if administration of laxatives is ineffective.

Intra- and inter-beat modeling of cardiovascular dynamics and control: assessing haemodynamic stability and responsiveness.

In critical care patient management, extensive and invasive patient monitoring is routinely performed in order to quantify patient status in view of therapeutic interventions. Little quantitative integration is performed when collecting information from multiple monitors, and processing algorithms are often based on little physiological understanding. Mechanistic modeling can offer insight into the mechanisms underlying patient stability and sensitivity to alterations in physiological variables.

Arterial blood pressure regulation following aorta clamping and declamping during surgery.

In this paper, we propose the use of black box models for the system identification of the cardiopulmonary baroreflex control of arterial resistance and of ventricular contractility and of arterial baroreflex control of heart rate (HR) from invasive, continuous measurements of arterial blood pressure (ABP) and central venous pressure (CVP), and non invasive, continuous recordings of ECG and respiration. Two crucial phases of the abdominal aortic aneurism (AAA) repair were investigated: the clamping and declamping of aorta. The objective of the present work is to evaluate and to test the ability to monitor baroreflex responses to clamping and declamping maneuvers preceding and following aneurism removal.

Estimation of baroreflex sensitivity during anesthesia induction with propofol.

This paper presents the analysis of the autonomic nervous system (ANS) control and cardiac baroreflex sensitivity in patients undergoing general anesthesia for major surgery, with the goal of evaluating the effects of anesthesia bolus induction with propofol on autonomic control of heart rate (HR) and arterial blood pressure (ABP). The increase in baroreflex gain in the LF band observed through two different methods hints at the fact that the baroreflex may increase heart period (HP) following a transient ABP decrease, but its response displays a larger amplitude, to compensate for the blunting of the sympathetic action on heart rate and vascular resistance.

Adherence and long-term effect of oxycodone/paracetamol in chronic noncancer pain: a retrospective study.

Introduction: Long-term administration of opiates in patients with chronic noncancer pain (CNCP) is subject to debate due to insufficient clinical evidence to support efficacy and tolerability.

Methods: This retrospective analysis used hospital records to investigate the effects of low doses of the combination of oxycodone/paracetamol on CNCP in an outpatient clinic setting to verify adherence to therapy and long-term efficacy. All patients receiving therapy for CNCP were examined between May and September 2010 and information was collected on medication, duration of therapy, and static and dynamic pain measured using numeric rating scales (NRS) from relevant charts.

Effects of opioid rotation in chronic pain patients: ORTIBARN study.

Background: Opioid rotation is currently the subject of considerable debate for two reasons: firstly as a strategy for pain treatment, and secondly because of the difficulty in determining equianalgesic doses. Switching from one slow-release (SR) opioid analgesic to another raises a number of critical issues, and there are no widespread studies that support a standard protocol. Initiation of opioid therapy must consider gradual dose titration of the drug until the minimum effective and maximum tolerated dosage for each patient is found.

Transdermal buprenorphine in non-oncological moderate-to-severe chronic pain.

Background: Musculoskeletal pathologies are among the most frequent causes of long-term non-oncological severe pain and consequent physical impairment. Aims of pharmacological and physical therapy are to reduce pain, promote functional recovery and improve overall quality of life. Pharmacological therapy may include the use of opioids.

Idiopathic breakthrough pain: a new hypothesis.

Breakthrough pain (BTP) in treated patients with chronic pain states is neither well defined nor well understood. BTP is generally defined as a transient exacerbation of pain experienced by a patient with relatively stable and adequately controlled baseline pain. It is usually categorized as spontaneous, with no known cause, or incident, when initiated by voluntary or involuntary movements, or therapeutic procedures.

Oxycodone/paracetamol: a low-dose synergic combination useful in different types of pain.

The combination of two analgesic agents offers several advantages in the treatment of chronic pain. Paracetamol (acetaminophen) has central analgesic activity without a nonsteroidal anti-inflammatory drug (NSAID)-like or opioid-like effect. Oxycodone is a semisynthetic opioid agonist.

Adequacy assessment of oxycodone/paracetamol (acetaminophen) in multimodal chronic pain : a prospective observational study.

Background: Multimodal pain is comprised of nociceptive/inflammatory and neuropathic components. Pharmacological pain therapies from different classes provide pain relief using different mechanistic actions; often a combination of such therapies provides more effective pain relief than monotherapy. To assess whether pain management is adequate requires a comprehensive pain scoring system.

Continuous femoral nerve block provides superior analgesia compared with continuous intra-articular and wound infusion after anterior cruciate ligament reconstruction.

Background And Objectives: This prospective, randomized, clinical trial compared pain intensity and analgesic drug consumption after anterior cruciate ligament (ACL) reconstruction with patellar tendon under femoral-sciatic nerve block anesthesia in patients who received either a continuous femoral nerve block (CFNB) or continuous local anesthetic wound and intra-articular infusions.

Methods: Fifty patients were randomized to CFNB (n = 25) or an ON-Q device (I-Flow Corp, Lake Forest, Calif) (n = 25). All patients received sciatic nerve block (25 mL of ropivacaine 7.

Controlled-release oxycodone and pregabalin in the treatment of neuropathic pain: results of a multicenter Italian study.

Aims: The aim of our study was to compare the efficacy, safety, and quality of life of combination therapy with controlled-release (CR) oxycodone plus pregabalin versus monotherapy with either CR oxycodone or pregabalin in patients with neuropathic pain.

Materials And Methods: Patients with moderate to severe neuropathic pain, despite the use of various pharmacologic treatments prior to study entry, were enrolled (n = 409) and treated with CR oxycodone plus pregabalin (n = 169), CR oxycodone (n = 106), and pregabalin (n = 134). Pain intensity was rated on an 11-point numerical rating scale (NRS).
