Evidence Based Interventional Pain Practice: According to Clinical Diagnoses Evidence based interventional pain practice: according to clinical diagnoses Introduction In 2012, the Nederlandse Vereniging voor Anesthesiologie Sectie Pijn- en Palliatieve geneeskunde (NVA) and the Vlaamse Anesthesiologische Vereniging voor Pijnbestrijding (VAVP) published a guideline on Interventional Pain Medicine. 1 As part of the original publication the authors highlighted that this guideline on interventional pain management can be considered an ongoing project. The searches that informed the original guidelines were at the start of this project in 2015 between 5.5 and 7.5 years out of date and so it is important that updates to this guidance include recently published literature. The methodology for literature retrieval; and selection of the publications to be withheld, as well as the method for evidence scoring, should evolve with each update”. The guideline committee decided to use the GRADE methodology, the current golden standard for the preparation of clinical guidelines. Background Clinical guidelines are systematically developed statements to assist practitioners and patients to make decisions about appropriate health care for specific clinical circumstances. NICE defines clinical guidelines as “recommendations based on the best available evidence, for the care of people by healthcare and other professionals.”2 A more detailed definition was provided by the Institute of Medicine (IOM) study entitled “Practice Guidelines That We Can Trust”: “Clinical practice guidelines are statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options.”3 As reflected in this definition, in order for guidelines to reflect the best available evidence it is important that they are based on a comprehensive systematic review of all available evidence. Systematic reviews provide an explicit approach to reviewing and summarizing evidence from studies. They follow a defined structure to identify, evaluate and summarize all available evidence addressing a particular research question. Key steps in a systematic review include specification of explicit inclusion criteria, an extensive literature search to identify all relevant studies, extraction of key data, assessment of the validity of included studies, and a structured statistical and/or qualitative synthesis of results.4 GRADE presents a systematic and transparent framework for clarifying questions, determining the outcomes of interest, summarizing the evidence that addresses a question, and moving from the evidence to a recommendation or decision. 5-8GRADE is currently the most widely accepted and used framework for developing guidelines. More than 50 organizations worldwide, many highly influential, have endorsed the framework (http://www.gradeworkinggroup.org/). It rates the quality of a complete body of evidence for a specific outcome in a specific population. Aim guideline The aim of the guideline is to update the evidence on efficacy of interventional pain management procedures. Content of the guideline In the original 2012 guideline we described for each diagnosis the definition of the diagnosis, the epidemiology, if known the etiology and pathophysiology, the signs and symptoms, if applicable the additional lab tests including X ray examination etc., the differential diagnosis, the evidence of conservative and interventional treatments, the technical aspects of the application of the invasive 2 pain management procedure and the place of the invasive procedures in the treatment algorithm. On this moment the updated guideline just limits to the quality of evidence, the considerations about risk and benefits, the cost effectiveness if available etc. and the recommendations. This updated guideline does not guide in the place of the interventional pain management procedure in the treatment algorithm. In general, interventional procedure will be offered to the patient if more conventional procedures have failed. Although in individual cases or procedures a deviation is imaginable. A next step in the process of making this guideline is creating more clarity about the place of these procedures in the treatment algorithm. This is especially important for referral doctors. Target audience The guideline is primarily intended for the anesthesiologist pain specialists applying these interventional pain managements procedures in their clinical practice. Other stakeholders are referring doctors, other workers in healthcare involved in these procedures and reimbursement policy makers. Patient perspective The patient associations were involved in the sticking point analysis before the start of the guideline development and will be involved in the authorization phase. In the implementation phase, individual hospitals will translate the content of the guideline in patient information leaflets and websites. Authorisation The guideline is authorized by the Nederlandse Vereniging voor Anesthesiologie, the Nederlandse Vereniging voor Neurologie and the Nederlandse Vereniging van Revalidatieartsen. Funding Project Guideline ‘Evidence based interventional pain practice’ development was funded by the Quality Fund for Medical Specialists (SKMS).

Kleijnen, MUMC Maastricht/York 4 Methods Research question What is the effectiveness of interventional pain management techniques that can be administered by anesthesiologists for the following conditions: 1 Trigeminal neuralgia 2 Cluster headache 3 Persistent idiopathic facial pain 4 Cervical radicular pain 5 Cervical facet joint pain 6 Cervicogenic headache 7 Whiplash Associated Disorders 8 Occipital neuralgia 9 Thoracic radicular pain 10 Thoracic facet joint pain 11 Lumbosacral radicular pain 11a Failed Back Surgery Syndrome 12 Lumbar facet joint pain 13 Spinal canal stenosis 14 Sacroiliac joint pain 15 Discogenic pain 16 Complex regional pain syndrome 17 Herpes zoster and postherpetic neuralgia 18 Painful diabetic polyneuropathy 19 Meralgia paresthetica 20 Carpal tunnel syndrome 21 Phantom pain 23 Traumatic plexus lesion 25 Chronic refractory angina pectoris 26a Raynaud’s syndrome 26 Chronic ischemic pain of the extremities 27 Chronic pancreatitis 28 Pain in patients with cancer Sticking point analysis After determining the research question, we did a sticking point analysis. We performed an inventory of sticking points in health care and possible impeding factors for the introduction of the future directive. We questioned the following stakeholders: Nederlandse Vereniging voor Neurochirurgie, Nederlandse Vereniging voor Orthopedie, Nederlandse Vereniging voor Neurologie, Koninklijk Genootschap van Fysiotherapeuten, Nederlands Huisartsen Genootschap Vereniging van Revalidatieartsen. 5 V&VN pijnverpleegkundigen/verpleegkundig specialisten pijn, Nederlands Instituut van Psychologen Pijnpatienten naar één stem Nederlandse Vereniging voor Rugpatiënten We received answers from Pijnpatienten naar één stem and the NHG. Pijnpatienten naar één stem asked attention for 2 topics, namely: 1. Communication (treatment, not being taken seriously, not listening well, joint decision making, talking about sexuality, little consultation between practitioners, unclear head treatment, adherence) and 2. Satisfaction (obtained advice and the result of the treatment are disappointing, waiting list). The NHG asked for a connection of the updated guideline to NHG Standards (NHG-Standard Pain) Review of the literature An independent epidemiologist, Prof.dr. J. Kleijnen, MUMC, Maastricht/York, was asked to review the literature. This review aimed to identify and summarize relevant evidence using GRADE methodology to inform guidelines on interventional pain management produced by the NVA and VAVP. This objective was achieved by: conducting a review of existing systematic reviews, randomized controlled trials (RCTs) and, where appropriate, observational studies of pain management for Trigeminal Neuralgia; Cluster Headache; Persistent Idiopathic Facial Pain; Cervical Radicular Pain; Cervical Facet Pain; Cervicogenic Headache; Whiplash-Associated Disorders; Occipital Neuralgia; Thoracic Pain; Lumbosacral Radicular Pain; Failed back surgery syndrome; Pain due to Spinal Canal Stenosis; Pain Originating from the Lumbar Facet Joints; Sacroiliac Joint Pain; Discogenic Low Back Pain; Complex Regional Pain Syndrome; Herpes Zoster and Post-Herpetic Neuralgia; Painful Diabetic Polyneuropathy; Carpal Tunnel Syndrome; Meralgia Parasthetica; Phantom Pain; Traumatic Plexus Lesion; Pain in Patients with Cancer; Chronic Refractory Angina Pectoris; Ischemic Pain in the Extremities and Raynaud’s Phenomenon and Pain in Chronic Pancreatitis.

  • Third Molar (Wisdom) Teeth
    Third molar (wisdom) teeth This information leaflet is for patients who may need to have their third molar (wisdom) teeth removed. It explains why they may need to be removed, what is involved and any risks or complications that there may be. Please take the opportunity to read this leaflet before seeing the surgeon for consultation. The surgeon will explain what treatment is required for you and how these issues may affect you. They will also answer any of your questions. What are wisdom teeth? Third molar (wisdom) teeth are the last teeth to erupt into the mouth. People will normally develop four wisdom teeth: two on each side of the mouth, one on the bottom jaw and one on the top jaw. These would normally erupt between the ages of 18-24 years. Some people can develop less than four wisdom teeth and, occasionally, others can develop more than four. A wisdom tooth can fail to erupt properly into the mouth and can become stuck, either under the gum, or as it pushes through the gum – this is referred to as an impacted wisdom tooth. Sometimes the wisdom tooth will not become impacted and will erupt and function normally. Both impacted and non-impacted wisdom teeth can cause problems for people. Some of these problems can cause symptoms such as pain & swelling, however other wisdom teeth may have no symptoms at all but will still cause problems in the mouth. People often develop problems soon after their wisdom teeth erupt but others may not cause problems until later on in life.

  • Would You Go to Your PCP for a Toothache? He Or She Is Trained in All Aspects of the Human Body and Has a Good Understanding of the Teeth and Gums
    WOULD YOU GO TO YOUR PCP FOR A TOOTHACHE? I pose the question, "Would you go to your PCP for a toothache? He or she is trained in all aspects of the human body and has a good understanding of the teeth and gums. He or she knows that healthy teeth play an important part in overall health, so certainly one would think that going to him or her might be a good option. But you don't. Why not? Well, because we all know that a dentist has more specific training, knowledge and experience with teeth and related matters. In fact, even if you did go to your PCP, I bet 99.99% or more would send you to your dentist, and you would thank them and do so without hesitation. This Photo by Unknown Author is licensed under CC BY-NC-ND So, who should you see if you are having musculoskeletal problems? To this day about 86% of people would select their primary physician or equivalent medical practice for these issues. Is that any smarter than seeing him or her for your teeth? Studies in 2004, 2006 and 2007 found that not only were the areas of spinal dysfunction and mechanical back pain not understood by the medical doctors, but most had little if any training in the area and almost no experience treating it. The typical response to treating low back pain is still to provide pain medication, muscle relaxants, order an x-ray and possibly refer to physical therapy. This is the routine in spite of the 1994 U.S.

    AĞRI 2009;21(4):133-140 REVIEW - DERLEME Neurolytic blocks: When, How, Why Nörolitik bloklar: Ne zaman, Nasıl, Niçin Serdar ERDİNE1 Summary Interventional techniques are divided into two categories: neuroablative and neuromodulatory procedures. Neuroablation is the physical interruption of pain pathways either surgically, chemically or thermally. Neuromodulation is the dynamic and functional inhibition of pain pathways either by administration of opioids and other drugs intraspinally or intraventricularly or by stimulation. Neuroablative techniques for cancer pain treatment have been used for more than a century. With the de- velopment of imaging facilities such as fl uoroscopy, neuroablative techniques can be performed more precisely and effi ciently. Key words: Neuroablative techniques; neurolytic blocks; radiofrequency thermocoagulation. Özet Girişimsel teknikler nöroablatif ve nöromodülatör işlemler olarak iki gruba ayrılırlar. Nöroablasyon, cerrahi, kimyasal veya ısı uy- gulamalarıyla ağrı yolaklarında fi ziksel iletinin kesilmesidir. Nöromodülasyon, stimülasyon uygulamasıyla veya intraventriküler ya da intraspinal uygulanan opioidler ve diğer ajanlarla ağrı yolaklarının dinamik ve fonksiyonel inhibisyonudur. Nöroablatif teknik- ler kanser tedavisinde yüzyıldan fazla zamandır kullanılmaktadır. Fluroskopi gibi görüntüleme araçlarındaki gelişmelerle nöroabla- tif uygulamalar daha doğru ve etkili bir şekilde gerçekleştirilmektedir.

  • Clinical Diagnosis of Herpes Zoster Presenting As Odontogenic Pain
    대한치과보존학회지: Vol. 33, No. 5, 2008 Clinical Diagnosis of Herpes Zoster Presenting as Odontogenic Pain Seong-Hak Yang, Dong-Ho Jung, Hae-Doo Lee, Yoon Lee, Hoon-Sang Chang, Kyung-San Min* Department of Conservative Dentistry, College of Dentistry, Wonkwang University ABSTRACT Herpes zoster, an acute viral infection produced by the varicella zoster virus, may affect any of the trigeminal branches. This case report presents a patient with symptoms mimicking odontogenic pain. No obvious cause of the symptoms could be found based on clinical and radiographic examinations. After a dermatologist made a diagnosis of herpes zoster involving the third trigeminal branch, the patient was given antiviral therapy. Two months later, the facial lesions and pain had almost disap- peared, and residual pigmented scars were present. During the diagnostic process, clinicians should keep in mind the possibility that orofacial pain might be related to herpes zoster.

    ADVICE SHEET WHAT TO DO IF YOU HAVE TOOTHACHE PAIN SYMPTOMS: ✅ Comes on when eating or drinking ✅ Lasts seconds or minutes ✅ Not disturbing sleep ✅ Can be relieved by painkillers ✅ Difficult to localise to one specific tooth [email protected] 0141 779 9274 8 Station Road, Muirhead www.hannigandentalcare.co.uk Glasgow, G69 9EE Page 1 of 6 ADVICE: WHAT TO DO IF YOU HAVE TOOTHACHE Sensitivity/Reversible Toothache PAIN SYMPTOMS: ✅ Comes on when eating or drinking ✅ Lasts seconds or minutes ✅ Not disturbing sleep ✅ Can be relieved by painkillers ✅ Difficult to localise to one specific tooth If this sounds like the type of pain you are experiencing then it is likely you are suffering from sensitivity. This is usually relieved with the use of a desensitising toothpaste, e.g. Sensodyne Rapid Relief. You should use a desensitising toothpaste every morning and night; place it on to a dry toothbrush and brush round – do not rinse out with water or mouthwash afterwards and do not have anything to drink for 30 minutes afterwards. Each time you use these toothpastes they form a microscopic layer on the teeth; with each use this barrier layer gets thicker and thus more effective at insulating the tooth from the hot/cold, so it takes about 2 weeks before it’s working at its optimum. If you are going to have e.g. a cold drink you can rub some directly on to the sensitive tooth with your finger for a minute beforehand and this should help to desensitise it. If you stop using these toothpastes the protective layer will eventually get washed away and your sensitivity will return.
