Shoulder Pain – Complexity to Simplicity
Shoulder Pain – Complexity to Simplicity A Regional Approach to Shoulder Pain The best way to approach a problem of shoulder pain is to look at the pain from a regional point of view. This allows for easy identification of specific pathological problems that occur at each region. In this talk, we look at the patterns of pain that occur with the different regions around the shoulder. From this, we will focus on the pathological problems that can be expected in each region and then look at specific physical examination findings that can be used to confirm a diagnosis or help further clarify the problem. Although this talk is focused on the diagnosis of causes of shoulder pain, we also take a look at some updates and salient features of treatment. In general, pain in the region of the shoulder can be grouped into 4 main types. These relate to specific patterns of pain that allow history taking to help us focus on the likely cause(s) before moving on to examination. A fairly clear-cut diagnosis is almost always achievable without the need to resort to special tests to help make the diagnosis. Of course, this does not include all possible causes of pain. The uncommon problem will still need a thorough and complete approach to determining cause, often with the requirement for special investigations. Remember that this is a good guide. Don't neglect other causes of referred pain that may cause pain in and around the shoulder. Included here is cardiac pain, diaphragmatic pain, apical lung disease and malignant bone pain. -

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). -
Studies on Brain and Spinal Cord Tumors
Studies on Brain and Spinal Cord Tumors Chapter 1 Osteochondroma of the Spine Iraj Lotfinia Professor of Neurosurgery, Tabriz Universsity of medical science, Tabriz, Iran. Fax: 00984113340830; Email: [email protected] Abstract Osteochondroma (OC) is the most common benign tumor of the bones, and it remains the most common precursor for secondary chondrosarcoma, which often occurs in the long bones’ metaphyseal areas. Rarely, it is also found in the spine. This tumor comprises a cartilage capped bone projection and is observed in both solitary and multiple forms. In many cases, the lesion can be definitively diagnosed according to radiological characteristics, but the rarity of these lesions in the spine, gradual onset of symptoms, and the frequent lack of observation of lesions in plain radiography may delay the diagnosis or cause misdiagnosis. These lesions are be- nign and do not risk the patient’s life; however, they rarely may be found to be a malignant degeneration that transformed into chondrosarcoma. When the lesion has led to clinical symptoms or has faced the patient with cosmetic challenges, or when definitive diagnosis is unknown, treatment is required. The primary treatment is the surgical removal of the lesion. Timely diagnosis and complete resection of the le- sion using surgery lead to complete recovery and prevent recurrence. 1. Introduction According to the World Health Organization’s (WHO’s) definition in 2002, osteocar- tilaginous exostosis are benign bone neoplasms covered by a cartilaginous cap created at the outer surface of the bone by endochondral ossification [1]. Osteochondroma (OC) is the most common benign primary tumor of the bone. -
Anesthetic Or Corticosteroid Injections for Low Back Pain
Anesthetic or Corticosteroid Injections for Low Back Pain Examples Trigger point injections. Sometimes, putting pressure on a certain spot in the back (called a trigger point) can cause pain at that spot or extending to another area of the body, such as the hip or leg. To try to relieve pain, a local anesthetic, either alone or combined with a corticosteroid, is injected into the area of the back that triggers pain (trigger point injection). Facet joint injections. A local anesthetic or corticosteroid is injected into a facet joint, which is one of the points where one vertebra connects to another. Epidural injections. A corticosteroid is injected into the spinal canal where it bathes the sheath that surrounds the spinal cord and nerve roots. These injections can be done by an orthopedist, an anesthesiologist, a neurologist, a physiatrist, a pain management specialist, or a rheumatologist. How It Works Local anesthesia is believed to break the cycle of pain that can cause you to become less physically active. Muscles that are not being exercised are more easily injured. Then the irritated and injured muscles can cause more pain and spasm and can disrupt sleep. This pain, spasm, and fatigue, in turn, can lead to less and less activity. Steroids reduce inflammation. So a corticosteroid injected into the spinal canal can help relieve pressure on nerves and nerve roots. Why It Is Used Injections may be tried if you have symptoms of nerve root compression or facet inflammation and you do not respond to nonsurgical therapy after 6 weeks. How Well It Works Research has not shown that local injections are effective in controlling low back pain that does not spread down the leg.footnote1 Side Effects All medicines have side effects. -

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.
