    Full Text Available Background. Causalgia is continuing pain, allodynia, or hyperalgesia after nerve injury with edema, changes in skin blood flow, or abnormal sudomotor activity. Here we report a case of lower extremity causalgia following elective transsphenoidal resection of a pituitary tumor in a young man. Clinical Presentation. A 33-year-old man with acromegaly underwent elective sublabial transsphenoidal resection of his pituitary tumor. During the three-hour surgery, the lower limbs were kept in a supine, neutral position with a pillow under the knees. The right thigh was slightly internally rotated with a tape to expose fascia lata, which was harvested to repair the sella. Postoperatively, he developed causalgia in a distal sciatic and common peroneal nerve distribution. Pain was refractory to several interventions. Finally, phenoxybenzamine improved his pain significantly. Conclusions. Malpositioning in the operating room resulted in causalgia in this young man. Phenoxybenzamine improved, and ultimately resolved, his symptoms. Improvement in his pain symptoms correlated with resolution of imaging changes in the distal sciatic and peroneal nerves on the side of injury.

    Ten patients are described in whom various involuntary movement disorders developed after trauma that was predominantly or entirely peripheral. The interval between injury and onset of movement disorder ranged from 48 hours to 3 years; the injured and painful part was the area initially affected by involuntary movements, although more widespread involvement subsequently occurred. These clinical features resemble the phenomena experienced by some patients with causalgia and suggest the possibility of common mechanisms.

  3. Facilitação e dominância dos sintomas sôbre a dor da angina de peito e causalgia

    Full Text Available O autor traz à consideração clínica a "facilitação" que Sherrington apreciou nos experimentos de neurofisiologia, e que explica aspectos clínicos importantíssimos em psicologia e em neurologia visceral. 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. Debate-se a superestimada psicogenia da angina de peito.

    1992-06-01

    In 1864, W. Mitchell and colleagues first described the clinical syndrome which came to be known as 'causalgia'. Since that time, the concept of sympathetically related pain has evolved. There is general agreement that profound emotional and behavioural changes can follow these types of pain. Opinions have varied widely on the issue of a psychological etiology. It has often been suggested that certain personality traits predispose one to develop sympathetically related pain syndromes. A review of the literature reveals no valid evidence to substantiate this claim.

    Full Text Available O objetivo do presente trabalho é avaliar os resultados iniciais obtidos com a simpatectomia cervicotorácica videotoracoscópica. De outubro de 1995 a outubro de 1997 foram realizados 24 procedimentos em 14 pacientes: dez homens e quatro mulheres, com idades que variaram de 16 a 56 anos, média de 30 anos. Indicações para a operação foram: hiperidrose palmar em dez pacientes, isquemia de mão em três e causalgia em um. Nos casos de hiperidrose, a ressecção da cadeia simpática incluiu T2 e T3. Nos portadores de isquemia e causalgia também o gânglio estrelado foi ressecado. Vinte e três das 24 extremidades mostraram excelente resposta imediata à simpatectomia. Somente uma extremidade de paciente com hiperidrose permaneceu inalterada devido a procedimento incompleto, tendo sido desnervada pela mesma técnica em reoperação posterior, com bom resultado. Pneumotórax residual pós-operatório ocorreu em uma paciente com resolução espontânea. Treze pacientes tiveram seguimento que variou de dois a 18 meses, com média de 11 meses. Não houve mortalidade nessa série, e a principal complicação tardia observada nos pacientes operados por hiperidrose foi a hiperidrose compensatória, que ocorreu, em grau variado, nos nove pacientes com seguimento, sendo que em 30% deles esta manifestação foi significativa.

    2009-01-01

    We present the case of a 33-year-old woman with benign sporadic monomelic amyotrophy of the distal part of the arm, called Hirayama disease. Clinical features included forearm amyotrophy sparing the brachioradialis muscle, cold paresis and causalgia. Neck magnetic resonance imaging was normal in neutral and flexion position. Electromyography showed denervated patterns in the extensor digitorum communis, and conduction studies ruled out multifocal motor neuropathy. Motor evoked potentials were normal. Serum IgG anti-GM1 antibodies were moderately raised but were negative 8 months later. Outcome was favourable within 15 months, with partial motor recovery. Pathogenesis remains controversial: neck flexion induced myelopathy via chronic anterior horn ischaemia due to forward displacement of the posterior wall of the dura mater, or benign variant of lower motor neuron disease? Whatever the pathomechanism is, the clinical features and outcome are the same.

  11. Publications on Peripheral Nerve Injuries during World War I: A Dramatic Increase in Knowledge.

    2016-01-01

    Publications from French (Jules Tinel and Chiriachitza Athanassio-Bénisty), English (James Purves-Stewart, Arthur Henry Evans and Hartley Sidney Carter), German (Otfrid Foerster and Hermann Oppenheim) and American (Charles Harrison Frazier and Byron Stookey) physicians from both sides of the front during World War I (WWI) contributed to a dramatic increase in knowledge about peripheral nerve injuries. Silas Weir Mitchell's original experience with respect to these injuries, and particularly causalgia, during the American Civil War was further expanded in Europe during WWI. Following the translation of one of his books, he was referred to mainly by French physicians. During WWI, several French books were in turn translated into English, which influenced American physicians, as was observed in the case of Byron Stookey. The establishment of neurological centres played an important role in the concentration of experience and knowledge. Several eponyms originated during this period (including the Hoffmann-Tinel sign and the Froment sign). Electrodiagnostic tools were increasingly used.

    2016-01-01

    We present the case of a 24 yr old male who was diagnosed with gluteal compartment syndrome and was subsequently found to have developed lumbosacral radiculoplexopathy and complex regional pain syndrome. The patient's gluteal compartment syndrome was diagnosed within 24 h of presentation to the emergency room, and he underwent emergent compartment release. While recovering postoperatively, persistent weakness was noted in the right lower limb. Results of electrodiagnostic testing were consistent with a lumbosacral radiculoplexopathy. After admission to inpatient rehabilitation, the patient complained of pain, burning sensation, and numbness in the distal right lower limb. Based on clinical findings, he was diagnosed with complex regional pain syndrome type II, or causalgia, and was referred for a lumbar sympathetic block under fluoroscopic guidance. Sympathetic block resulted in relief of the patient's symptoms. He was discharged home with good pain control on oral medications.

    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.

  14. Amputations and prosthetics.

    Pinzur, M S

    1999-01-01

    The author presents in a condensed way an overview of the principles of limb amputations and further treatment of patients who underwent such a procedure. The metabolic cost of walking, load transfer, and wound healing are reviewed in a concise manner. Particular attention is given to blood supply to the wound and methods to determine adequate perfusion with a clear analysis of the pro and cons of the Doppler method. Pediatric amputations, because of their specificity, are considered apart. Disarticulation of limbs is the method of choice in children, because of it retains growth potential of the bone and prevents bony overgrowth of the stump. The article discusses the main indications for limb amputations: trauma, peripheral vascular disease, musculoskeletal tumors and gas gangrene. In every case the specificity of the amputation is considered by the author. Postoperative care is also presented, with a short description of possible complications. Pain is the most common and treatment strategies should be similar to those used in treating patients with major reflex sympathetic causalgia. Edema, joint contracture, wound failure and dermatologic problems are all shortly reviewed. The last part of the article treats with the principles of prosthetics in both the upper and lower limb. These principles are presented basing on the level of amputation: for the upper limb hand, transradial, transhumeral amputations and shoulder disarticulation. For the lower limb foot and ankle, transtibial and transfemoral amputations are considered.

    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.

  16. Silas Weir Mitchell and "The Strange Case of George Dedlow".

    It has been said of Silas Weir Mitchell (1829-1914) that as a young man he was first among the physiologists of his day, in middle age first among physicians, and as an older man, one of the most noted novelists of his country. Mitchell's novels were written in his later life as a means to avoid boredom during lengthy summer vacations that were the norm for that time among the affluent members of Philadelphia society. These novels were criticized by some because of poor plots, which in some instances failed to move along, or for text that offered a stereotyped depiction of genteel society and the effects that war or personal disaster had on the characters' behavior The criticism came despite the fact that all critics agreed that Mitchell's portrayals of psychopathology in his fictional characters was unique and accurate. However, in his 30s, Mitchell had written and by chance had published a fictional short story that not only transcended such criticisms but became immensely popular. "The Strange Case of George Dedlow" portrays a union officer who was not a physician but who had some medical background and who sustained a series of war wounds leading to severe nerve pain, the author's first description of causalgia, multiple amputations, and the psychological as well as physical symptoms of phantom limb syndrome. The protagonist tells of his torments in the first person in a very engaging fashion. Thus, long before he began writing his, at that time, acclaimed novels in the 1880s, Mitchell wrote a piece of fiction that combines accurate and very important medical observations with fiction of great historical interest. The following rendering of this now classic short story includes selected quotes and some interpretation and is perhaps appropriate for this year, 2 years after the centenary year of his death in 1914.

Para poder identificarlo es necesario conocerlo; produce un dolor espontáneo que cursa con hiperalgesia y alodinia como fenómenos distorsionados sensoriales, variaciones de flujo sanguíneo, sudoración y cambios tróficos por un estado inflamatorio localizado seguido por una etapa de desórdenes crónicos neuropáticos. Su presencia está relacionada más frecuentemente a un trauma inespecífico o un daño directo sobre una estructura nerviosa en las extremidades. Clásicamente es dividido en dos formas: Tipo I, anteriormente denominado Distrofia simpática refleja y el Tipo II, más conocido por el término de Causalgia. No ha sido posible establecer su fisiopatología, sin embargo se reconoce que se involucra todo el sistema nervioso para su instauración. Dentro de la práctica diaria del médico forense costarricense, se presenta la valoración de daño corporal en el ámbito laboral, penal y contencioso administrativo, por lo que es trascendental aprender a identificarlo, pues hay casos con factores en los cuales este síndrome puede ser planteado como secuela directa.

  18. Neuralgias of the Head: Occipital Neuralgia.

    Choi, Il; Jeon, Sang Ryong

    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.
