    This is a personal assessment of true major causalgia and the other reflex dystrophies, related but distinctly separate entities. The clinical picture of causalgia differs only in minor respects from that described by Mitchell over 120 years ago. Its management has, however, been clarified, largely through the extensive experiences of World War II. It is readily recognized and can be treated effectively by sympathetic blocks or sympathectomy together with active exercise. The other reflex dystrophies are far less understood. They appear to have a similar pattern in their early phase and to respond well to a program of exercise and control of edema--a regimen which, because of pain and paresis, cannot be carried out without sympathetic blocks or occasionally sympathectomy. When not recognized early and treated properly, the sympatomatology usually changes dramatically and treatment differs. Often control of edema and active use of the affected part are all that is necessary. Sometimes, in addition to these measures, sympathetic blocks or sympathectomy is required. Guidelines found useful in management are outlined. Puzzling features are discussed. PMID:3977427

    The symptomatology of reflex sympathetic dystrophy (RSD), a diagnostic term which today includes causalgia and M. Sudeck, is characterized clinically by a triad of autonomic (sympathetic), motor and sensory disturbances. They develop following a noxious event--though independent of its nature and location--in a generalized distribution pattern at the distal site of the affected extremity. Pathophysiologically, a complex disturbance of the sympathetic vasoconstrictor system is involved, which mediates the dominant symptoms of RSD, namely the spontaneous pain and the swelling. This disturbance is thought to be initiated by nociceptive impulses, occurring in conjunction with the preceding noxious event, and to be maintained reflexly, in a form of a vicious circle, by means of the typical pain sensation accompanying the RSD-syndrome. From these ideas, an important part of the RSD therapy is deduced; i.e. the early interruption of the neuronal sympathetic activity by means of a sympathetic blockade. Such a blockade can interrupt the pain and at the same time also the vicious circle of RSD. Altogether, for the RSD syndrome there are relevant neurological aspects with respect to its clinical symptomatology, its pathophysiology and its therapy. PMID:1713305

Pretende o autor explicar seus casos de dor (um de causalgia no membro superior e três de angina de peito em portadores de esclerose coronária. Ora a anestesia terapêutica no gânglio estrelado, ora na cadeia ganglionar torácica simpática, ora a radioterapia, ora a psicoterapia removeram a dor "facilitada" a tal ponto que se tornara "dominante", isto é, mesmo estímulos inadequados a provocavam. Os doentes eram inválidos e recuperaram-se. A neurofisiologia moderna autoriza a interpretação dessa terapêutica: suprimiu-se - com a anestesia, com a radioterapia e com a psicoterapia - o circuito neural auto-alimentado reverberante, hiperfuncionante em todo ou em parte de seu trajeto, quer aferente ao córtex quer aferente às coronárias. O autor discute o valor clínico dos acessos anginosos apontando fatos que documentam que o acesso "ilegítimo" (psicógeno deve ter como causa a estimulação das aferências vegetativas ao córtex em qualquer ponto (ganglionar, medular ou cortical. Os acessos "legítimos", produzindo lesões transitórias ou definitivas e até morte,, devem ser explicados pela atividade das eferências vagais que executam os efetôres espásticos das coronárias. A dor é apresentada como fenômeno de "gravação neural", aprendido, memorizado e automatizado, ativado em feed-back ora nas aferências vegetativas ao córtex, ora nas eferências, mais perigosas e mortais.

    Full Text Available Background: Post injection sciatic nerve injury is a common cause of sciatic nerve mononeuropathy in the developing world largely due to inadequate health care facilites in the rural regions. Objective: The study was conducted to analyse the pattern of this nerve lesion in clinical and electrophysiological parameters and also to study the outcome in a conservatively treated cohort. Materials and Methods: One hundred and six patients who underwent evaluation at our laboratory from 2000 to 2006 for post injection sciatic neuropathy formed the study population. Twenty two of these were followed up (mean 6.6 months for the outcome. Results: In the cases with full data, common peroneal division of the sciatic nerve was affected alone or predominantly. On follow up, 72% cases showed little or partial recovery. Thirty two percent patients had residual trophic changes and causalgia at their last visit. Conclusion: The majority of cases of postinjection sciatic nerve injury have poor prognosis on conservative treatment.

    Full Text Available Complex Regional Pain Syndrome is a symptom complex including severe pain which is disproportioned by the initiating event. Formerly, it was known as reflex sympathetic dystropy, Sudeck’s atrophy and algoneurodystrophy. There are two types of complex regional pain syndrome (CPRS. CRPS type 1 (Reflex sympathetic dystropy occurs after a minor trauma of the extremities, CRPS type 2 (Causalgia occurs following peripheral nevre injury. Diagnosis is made according to the history, symptoms and physical findings of the patients. Patient education, physical therapy and medical treatment are the most common treatment approaches of complex regional pain syndrome. The aim of this review is to revise the treatment options ofcomplex regional pain syndrome, as well as to overview the new treatment approaches and options for the refractory complex regional pain syndrome cases.

    The history of algodystrophy discerning, its recognition as a separate clinical entity and evolution of ideas about its nature is presented on the basis of historical and scientific literature. First cases resembling algodystrophy were described as early as in XVI and XVIII century. A more detailed description of limb dystrophy that followed gunshot injuries was reported by American surgeon Weir Mitchell in 1864, who coined this condition as "causalgia". In the year 1900 Paul Sudeck of Germany described radiological changes secondary, as he believed, to inflammatory process within the limb as patchy osteoporosis. His name is still attached to this syndrome in German and Polish literature. French neurosurgeon Rene Leriche believed, that the syndrome was caused by increased activity of the sympathetic nervous system and introduced a surgical periarterial sympathectomy. Oscar Steinbrocker of the United States separated particular form of algodystrophy known as shoulder-hand syndrome; later, he introduced the treatment of this condition with steroids. PMID:9377976

    This paper reviews the contribution of Sudeck to the understanding of the condition commonly referred to as 'Sudeck's atrophy' and which is commonly used as a synonym for a condition variously called reflex sympathetic dystrophy, causalgia, algodystrophy and others. Sudeck came to show in his later papers that the so-called atrophy was, in the majority of cases, a normal inflammatory process of bone change in the course of healing after an inflammatory/infective or traumatic insult. Contrary to the views of much current literature, the vast majority of such cases had a good prognosis. In those cases which became pathological and had a correspondingly poorer prognosis, the characteristic clinical picture becomes associated with radiological and pathological changes, which, uniquely, are described by Sudeck. A knowledge of such radiological and pathological substrate for clinical symptomatology is important in the analysis of pain following trauma. PMID:17274178

    Full Text Available Abstract Introduction We report on a very rare case of a cervical ligamentum flavum cyst, which presented with progressive myelopathy and radiculopathy. The cyst was radically extirpated and our patient showed significant recovery. A review of the relevant literature yielded seven cases. Case presentation An 82-year-old Greek woman presented with progressive bilateral weakness of her upper extremities and causalgia, cervical pain, episodes of upper extremity numbness and significant walking difficulties. Her neurological examination showed diffusely decreased motor strength in both her upper and lower extremities. Magnetic resonance imaging of her cervical spine demonstrated a large, well-demarcated cystic lesion on the dorsal aspect of her spinal cord at the C3 to C4 level, significantly compressing the spinal cord at this level, in close proximity to the yellow ligament and the C3 left lamina. The largest diameter of this lesion was 1.4 cm, and there was no lesion enhancement after the intravenous administration of a paramagnetic contrast. The lesion was surgically removed after a bilateral C3 laminectomy. The thick cystic wall was yellow and fibro-elastic in consistency, while its content was gelatinous and yellow-brownish. A postoperative cervical-spine magnetic resonance image was obtained before her discharge, demonstrating decompression of her spinal cord and dural expansion. Her six-month follow-up evaluation revealed complete resolution of her walking difficulties, improvement in the muscle strength of her arms (4+/5 in all the affected muscle groups, no causalgia and a significant decrease in her preoperative upper extremity numbness. Conclusion Cervical ligamentum flavum cysts are rare benign lesions, which should be included in the list of differential diagnosis of spinal cystic lesions. They can be differentiated from other intracanalicular lesions by their hypointense appearance on T1-weighted and hyperintense appearance on T2

    Subcutaneous atrophy is a known complication of steroid injections. Excellent results with fat grafting for the treatment of steroid atrophy have been documented. However, the benefit of treating steroid-induced subcutaneous atrophy in an extremity diagnosed with complex regional pain syndrome (CRPS) has not been described. CRPS, known formerly as reflex sympathetic dystrophy or RSD, causalgia, or reflex neurovascular dystrophy, is a severe, progressive musculoskeletal pain syndrome characterized by pain which is disproportionate to the severity of the inciting event, edema, or skin changes. Common treatment modalities include pharmacotherapy, physical therapy, and nerve blocks-each therapy producing varying results. We present a literature review of CRPS and the case of a 15-year-old female who developed CRPS of the left lower leg after arthroscopic debridement with retrograde drilling of an osteochondral lesion. Steroid atrophy of the involved area following a saphenous nerve block complicated the patient's treatment course. The area of atrophy was treated with autologous fat grafting. Following the adipose injection procedure, the patient experienced almost complete resolution of her CPRS-associated pain symptoms, along with improved cosmetic appearance of the area. PMID:26735938

    Full Text Available Abstract The hypothesis is explored that CRPS I (the "new" RSD persists due to undiagnosed injured joint afferents, and/or cutaneous neuromas, and/or nerve compressions, and is, therefore, a misdiagnosed form of CRPS II (the "new" causalgia. An IRB-approved, retrospective chart review on a series of 100 consecutive patients with "RSD" identified 40 upper and 30 lower extremity patients for surgery based upon their history, physical examination, neurosensory testing, and nerve blocks. Based upon decreased pain medication usage and recovery of function, outcome in the upper extremity, at a mean of 27.9 months follow-up (range of 9 to 81 months, gave results that were excellent in 40% (16 of 40 patients, good in 40% (16 of 40 patients and failure 20% (8 of 40 patients. In the lower extremity, at a mean of 23.0 months follow-up (range of 9 to 69 months the results were excellent in 47% (14 of 30 patients, good in 33% (10 of 30 patients and failure 20% (6 of 30 patients. It is concluded that most patients referred with a diagnosis of CRPS I have continuing pain input from injured joint or cutaneous afferents, and/or nerve compressions, and, therefore, similar to a patient with CRPS II, they can be treated successfully with an appropriate peripheral nerve surgical strategy.

    With few exceptions, neurology was nonexistent in the United States until the Civil War years. From 1861 to 1865, the United States saw a bitter armed conflict between the North (the Union) and the South (the Confederate States or Confederacy), and during those years, neurology was born in the United States. In 1861, Silas Weir Mitchell, together with George Morehouse and William Keen, opened and operated the first neurological hospital in Philadelphia, with the backing of the Surgeon General William Hammond. They treated and studied many peripheral nerve diseases, which led to their making the medical world aware of several conditions, including causalgia (now known as complex regional pain syndrome) and the phantom limb phenomenon. Progress in neurology, both at that time and in subsequent years, owed a great deal to cross-fertilization from Europe. Charles Edouard Brown-Séquard exemplified this. He held multiple medical positions on both sides of the Atlantic, including a position at Harvard in 1864. His teachings, to some extent, contributed to the development of neurology in the United States. In the Confederate states, medical care was less well organized, and neurology only developed later. After the war, in 1874, Mitchell, Hammond, and a few others founded the American Neurological Association. While war influenced the development of medicine, and neurology in particular, medicine also helped to shape the outcome of the war. PMID:27035676

    The history of algodystrophy is controversial and its denomination has changed significantly over time. Silas Weir Mitchell described several cases of causalgia due to gunshot wounds that occurred during the American Civil War, increasing knowledge about this clinical condition. A later key milestone in the history of CRPS is tied to the name of Paul Sudeck that, using X-ray examinations, described findings of bone atrophy following a traumatic event or infection of the upper limb. The most widely accepted pathogenic hypothesis, proposed by Rene Leriche, supported a key role of the sympathetic nervous system in the onset of the typical clinical picture of the disease, which was thus defined as "reflex sympathetic dystrophy". In the 50s John J. Bonica proposed a staging of CRPS. In a consensus conference held in Budapest in 2003, it was proposed a new classification system that included the presence of at least two clinical signs included in the four categories and at least three symptoms in its four categories. There have been other classification systems proposed for the diagnosis of CRPS, such as Veldman diagnostic criteria based on the presence of at least 4 signs and symptoms of the disease associated with a worsening of the same following the use of the limb and their location in the same area distal to the one that suffered the injury. On the other hand, the Atkins diagnostic criteria are much more objective than those proposed by IASP and are specifically applicable to an orthopaedic context. However, current classification systems and related criteria proposed to make a diagnosis of CRPS, do not include instrumental evaluations and imaging, but rely solely on clinical findings. This approach does not allow an optimal disease staging especially in orthopaedics. PMID:27134625

    One of the biggest challenges for discovering more efficacious drugs for the control of neuropathic pain has been the diversity of chronic pain states in humans. It is now acceptable that different mechanisms contribute to normal physiologic pain, pain arising from tissue damage and pain arising from injury to the nervous system. To study pain transmission, spot novel pain targets and characterize the potential analgesic profile of new chemical entities, numerous experimental animal pain models have been developed that attempt to simulate the many human pain conditions. Among the neuropathic pain models, surgical models have paramount importance in the induction of pain states. Many surgical animal models exist, like the chronic constriction injury (CCI) to the sciatic nerve, partial sciatic nerve ligation (pSNL), spinal nerve ligation (SNL), spared nerve injury (SNI), brachial plexus avulsion (BPA), sciatic nerve transaction (SNT) and sciatic nerve trisection. Most of these models induce responses similar to those found in causalgia, a syndrome of sustained burning pain often seen in the distal extremity after partial peripheral nerve injury in humans. Researchers most commonly use these surgical models in both rats and mice during drug discovery to screen new chemical entities for efficacy in the area of neuropathic pain. However, there is scant literature that provides a comparative discussion of all these surgical models. Each surgical model has its own benefits and limitations. It is very difficult for a researcher to choose a suitable surgical animal model to suit their experimental set-up. Therefore, particular attention has been given in this review to comparatively provide the pros and cons of each model of surgically induced neuropathic pain. PMID:24831263

    2016-04-01

    Occipital neuralgia is defined by the International Headache Society as paroxysmal shooting or stabbing pain in the dermatomes of the greater or lesser occipital nerve. Various treatment methods exist, from medical treatment to open surgical procedures. Local injection with corticosteroid can improve symptoms, though generally only temporarily. More invasive procedures can be considered for cases that do not respond adequately to medical therapies or repeated injections. Radiofrequency lesioning of the greater occipital nerve can relieve symptoms, but there is a tendency for the pain to recur during follow-up. There also remains a substantial group of intractable patients that do not benefit from local injections and conventional procedures. Moreover, treatment of occipital neuralgia is sometimes challenging. More invasive procedures, such as C2 gangliotomy, C2 ganglionectomy, C2 to C3 rhizotomy, C2 to C3 root decompression, neurectomy, and neurolysis with or without sectioning of the inferior oblique muscle, are now rarely performed for medically refractory patients. Recently, a few reports have described positive results following peripheral nerve stimulation of the greater or lesser occipital nerve. Although this procedure is less invasive, the significance of the results is hampered by the small sample size and the lack of long-term data. Clinicians should always remember that destructive procedures carry grave risks: once an anatomic structure is destroyed, it cannot be easily recovered, if at all, and with any destructive procedure there is always the risk of the development of painful neuroma or causalgia, conditions that may be even harder to control than the original complaint.

    Full Text Available Scattered accounts of the treatment of pain by aboriginal Canadians are found in the journals of the early explorers and missionaries. French and English settlers brought with them the remedies of their home countries. The growth of medicine through the 18th and 19th centuries, particularly in Europe, was mirrored in the practice and treatment methods of Canadians and Americans. In the 19th century, while Americans learned about causalgia and the pain of wounds, Canadian insurrections were much less devastating than the United States Civil War. By the end of that century, a Canadian professor working in the United States, Sir William Osler, was responsible for a standard textbook of medicine with a variety of treatments for painful illnesses. Yet pain did not figure in the index of that book. The modern period in pain research and management can probably be dated to the 20 years before the founding of the International Association for the Study of Pain. Pride of place belongs to The management of pain by John Bonica, published in Philadelphia in 1953 and based upon his work in Tacoma and Seattle. Ideas about pain were evolving in Canada in the 1950s with Donald Hebb, Professor of Psychology at McGill University in Montreal, corresponding with the leading American neurophysiologist, George H Bishop. Hebb's pupil Ronald Melzack engaged in studies of early experiences in relation to pain and, joining with Patrick Wall at Massachusetts Institute of Technology, published the 1965 paper in Science that revolutionized thinking. Partly because of this early start with prominent figures and partly because of its social system in the organization of medicine, Canada became a centre for a number of aspects of pain research and management, ranging from pain clinics in Halifax, Kingston and Saskatoon - which were among the earliest to advance treatment of pain - to studying the effects of implanted electrodes for neurosurgery.
