The state is characterized by a paradoxical response least in the short term.3–14 whereby a patient receiving opioids for the treatment of pain Perhaps because of this new evidence, opioid may actually become more sensitive to certain painful stimuli. medications have been increasingly prescribed by primary The type of pain experienced may or may not be different from care physicians and other patient care providers for the original underlying painful condition.

Download the Herniated Disc Brochure
AN INTRODUCTION TO HERNIATED DISCS This booklet provides general information on herniated discs. It is not meant to replace any personal conversations that you might wish to have with your physician or other member of your healthcare team. Not all the information here will apply to your individual treatment or its outcome. About the Spine CERVICAL The human spine is comprised 24 bones or vertebrae in the cervical (neck) spine, the thoracic (chest) spine, and the lumbar (lower back) THORACIC spine, plus the sacral bones. Vertebrae are connected by several joints, which allow you to bend, twist, and carry loads. The main joint LUMBAR between two vertebrae is called an intervertebral disc. The disc is comprised of two parts, a tough and fibrous outer layer (annulus fibrosis) SACRUM and a soft, gelatinous center (nucleus pulposus). These two parts work in conjunction to allow the spine to move, and also provide shock absorption. INTERVERTEBRAL ANNULUS DISC FIBROSIS SPINAL NERVES NUCLEUS PULPOSUS Each vertebrae has an opening (vertebral foramen) through which a tubular bundle of spinal nerves and VERTEBRAL spinal nerve roots travel. FORAMEN From the cervical spine to the mid-lumbar spine this bundle of nerves is called the spinal cord. The bundle is then referred to as the cauda equina through the bottom of the spine. At each level of the spine, spinal nerves exit the spinal cord and cauda equina to both the left and right sides. This enables movement and feeling throughout the body. What is a Herniated Disc? When the gelatinous center of the intervertebral disc pushes out through a tear in the fibrous wall, the disc herniates. -

Clinical Data Mining Reveals Analgesic Effects of Lapatinib in Cancer Patients
www.nature.com/scientificreports OPEN Clinical data mining reveals analgesic efects of lapatinib in cancer patients Shuo Zhou1,2, Fang Zheng1,2* & Chang‑Guo Zhan1,2* Microsomal prostaglandin E2 synthase 1 (mPGES‑1) is recognized as a promising target for a next generation of anti‑infammatory drugs that are not expected to have the side efects of currently available anti‑infammatory drugs. Lapatinib, an FDA‑approved drug for cancer treatment, has recently been identifed as an mPGES‑1 inhibitor. But the efcacy of lapatinib as an analgesic remains to be evaluated. In the present clinical data mining (CDM) study, we have collected and analyzed all lapatinib‑related clinical data retrieved from clinicaltrials.gov. Our CDM utilized a meta‑analysis protocol, but the clinical data analyzed were not limited to the primary and secondary outcomes of clinical trials, unlike conventional meta‑analyses. All the pain‑related data were used to determine the numbers and odd ratios (ORs) of various forms of pain in cancer patients with lapatinib treatment. The ORs, 95% confdence intervals, and P values for the diferences in pain were calculated and the heterogeneous data across the trials were evaluated. For all forms of pain analyzed, the patients received lapatinib treatment have a reduced occurrence (OR 0.79; CI 0.70–0.89; P = 0.0002 for the overall efect). According to our CDM results, available clinical data for 12,765 patients enrolled in 20 randomized clinical trials indicate that lapatinib therapy is associated with a signifcant reduction in various forms of pain, including musculoskeletal pain, bone pain, headache, arthralgia, and pain in extremity, in cancer patients. -

AAFP Chronic Pain Toolkit
AAFP Chronic Pain Toolkit PAIN ASSESSMENT | Section 1 OVERVIEW Assessment of chronic pain should be multidimensional. Consideration should be given to several domains, including the physiological features of pain and its contributing factors, with physicians and other clinicians assessing patients for function, quality of life, mental health, and emotional health. In addition to a complete medical and medication history typically obtained at an office visit, documentation should be obtained about pain intensity, location, duration, and factors that aggravate or alleviate pain. A physical exam should include musculoskeletal and neurological components, as appropriate. Diagnostic testing and imaging may also be considered for some types of chronic pain. Many organizations, including the AAFP, recommend against imaging for low back pain within the first six weeks of treatment unless there are reasons for the imaging. These reasons may include concerns of underlying conditions, such as severe or progressive neurological deficits, or if osteomyelitis is suspected.1 Periodic reassessments of chronic pain and treatment should focus on evaluating improvements in physical health; mental and emotional health; progress towards functional treatment goals; and effectiveness and tolerability of medications for chronic pain treatment. Currently, there are no universally adopted guidelines or recommendations for assessment of chronic pain. The use of appropriate assessment tools can assist in diagnostic assessment, management, reassessment, and monitoring of treatment effects. Multiple tools are available, with many embedded in electronic health record (EHR) systems. Pain Assessment Tools The table on the next page includes selected tools for pain assessment included in this toolkit, along with links and reference to additional tools. Assessments about other relevant domains are covered in Functional and Other Assessments (Section 2). -

Pain Management in People Who Have OUD; Acute vs. Chronic Pain Developer: Stephen A. Wyatt, DO Medical Director, Addiction Medicine Carolinas HealthCare System Reviewer/Editor: Miriam Komaromy, MD, The ECHO Institute™ This project is supported by the Health Resources and Services Administration (HRSA) of the U.S. Department of Health and Human Services (HHS) under contract number HHSH250201600015C. This information or content and conclusions are those of the author and should not be construed as the official position or policy of, nor should any endorsements be inferred by HRSA, HHS or the U.S. Government. Disclosures Stephen Wyatt has nothing to disclose Objectives • Understand the complexities of treating acute and chronic pain in patients with opioid use disorder (OUD). • Understand the various approaches to treating the OUD patient on an agonist medication for acute or chronic pain. • Understand how acute and chronic pain can be treated when the OUD patient is on an antagonist medication. Speaker Notes: The general Outline of the module is to first address the difficulties surrounding treating pain in the opioid dependent patient. Then to address the ways that patients with pain can be approached on either an agonist of antagonist opioid use disorder treatment. Pain and Substance Use Disorder • Potential for mutual mistrust: – Provider • drug seeking • dependency/intolerance • fear – Patient • lack of empathy • avoidance • fear Speaker Notes: It is the provider that needs to be well educated and skillful in working with this population. Through a better understanding of opioid use disorders as a disease, the prejudice surrounding the encounter with the patient may be reduced. -
Pain Management Assessment and Reassessment
North Shore-LIJ Health System is now Northwell Health System Patient Care Services POLICY TITLE: CLINICAL POLICY AND PROCEDURE Pain Management: Assessment and MANUAL Reassessment POLICY #: PCS.1603 CATEGORY SECTION: System Approval Date: 10/20/16 Effective Date: NEW Site Implementation Date: 12/2/16 Last Reviewed/Revised: NEW Prepared by: Notations: System Nursing Policy and Procedure This policy was created by incorporating the Committee Northwell Health’s Geriatric Guidelines for Pain Management into the Northwell Health’s Pain Management : Assessment and Reassessment Policy dated 11/10 that can be found on the Intranet. GENERAL STATEMENT of PURPOSE To establish a standard for routine assessment, reassessment and documentation of pain as appropriate to the patient’s condition and treatment regimen. POLICY 1. Patients are screened and assessed for pain based upon clinical presentation, services sought, and in accordance with the care, treatment, and services provided. Facility personnel use methods to assess pain that are consistent with the patient’s age, condition, and ability to understand. 2. If the patient reports pain to a health care worker other than a licensed health care provider, the health care worker will escalate the report of pain to a licensed health care provider for assessment. 3. Pain assessment performed by health care providers will address individual, cultural, spiritual, and language differences. Pain measurement scales are available in various languages and, if necessary, access to a medical interpreter will be provided to assist in the evaluation of the patient’s pain. 4. The patient’s self-report of pain is considered the “gold standard.” For those patients who are unable to communicate the health care provider will assess pain by using the appropriate pain Measurement Scale. -
