Surgical Treatment Compared to Conservative Treatment in Remission of Pain and Hyposthesia in Tarsal Tunnel Syndrome ­ Systematic Review / Tratamento cirúrgico comparado ao tratamento conservador na remissão da dor e hipoestesia na síndrome do túnel do tarso ­ Revisão sistemática

Introduction Tarsal tunnel syndrome (TTS) is caused by compression of the posterior tibial nerve. Objective To evaluate the effectiveness of surgical treatments compared to conser vative treatments in reducing the symptoms of the syndrome. Methods The PubMed, Lilacs, Cochrane Library, and PEDro databases were used for this review. Results Only 11 articles were selected. Conclusion The most common causes of TTS identified were presence of ganglia, bone prominence causing a talocalcaneal collision, trauma, varicose and idiopathic veins. The main symptom was pain in the medial plantar region and paresthesia that can radiate to the fingers or to the calf. Most patients have a positive Tinel sign upon physical examination. Electrodiagnostic test usually shows the presence of latency in sensory nerve conduction. There is no consensus suggesting that a longer time between diagnosis and surgical treatment leads to worse prognosis. In the group of operated patients, the ones who benefited most from the procedure were those who had a structure such as ganglion, cysts, or varicosities causing compression. The most cited surgical complications were postsurgical wound infection, wound dehiscence, and calcaneus hypoesthesia. Regarding surgical techniques, the release of the posterior tibial nerve via endoscopy had a favorable outcome in relation to the symptoms of pain and hypoesthesia, with no reports of infection of the operative site in the articles identified in this review. We observed a rate of good or excellent pain control of 68% (n » 204) for open surgery (n » 299), 100% (n » 8) for endoscopic surgery (n » 8), and 7% (n » 2) for conservative treatment (n » 28).

Introdução A síndrome do túnel do tarso (STT) é causada pela compressão do nervo tibial posterior. Objetivo Avaliar a eficácia dos tratamentos cirúrgicos em comparação aos conservadores na redução dos sintomas da síndrome. Métodos Foram utilizados as bases de dados PubMed, Lilacs, Cochrane Library e PEDro. Resultados Apenas 11 artigos foram selecionados. Conclusão As causas mais comuns de STT identificadas foram presença de gânglios, proeminência óssea causando colisão talocalcânea, trauma, varizes e veias. O principal sintoma foi dor na região plantar medial e parestesia, que pode irradiar para os dedos ou panturrilha. A grande maioria dos pacientes apresenta um sinal de Tinel positivo no exame físico. O teste eletrodiagnóstico geralmente mostra a presença de latência na condução nervosa sensorial. Não há consenso de que o maior tempo entre o diagnóstico e o tratamento cirúrgico leva a um pior prognóstico. No grupo de pacientes operados, os que mais se beneficiaram com o procedimento foram aqueles que apresentavam estrutura como gânglio, cistos ou varicosidades causando compressão. As complicações cirúrgicas mais citadas foram infecção da ferida operatória, deiscência da ferida e hipoestesia do calcâneo. A cirurgia endoscópica teve evolução favorável em relação aos sintomas de dor e hipoestesia, não havendo relato de infecção do sítio operatório. Observou-se que a taxa de bom ou excelente controle da dor foi de 68% (n » 204) para cirurgia aberta (n » 299), 100% (n » 8) para cirurgia endoscópica (n » 8), e 7% (n » 2) para o tratamento conservador (n » 28).

Epidemiology and Estimated Cost of Surgery for Cubital Tunnel Syndrome Conducted by the Unified Health System in Brazil (2005­2015)

Introduction Cubital tunnel syndrome (CTS) is responsible for one of the types of ulnar nerve neuropathy and is the second cause of compressive neuropathy of the upper limb, only surpassed by carpal tunnel syndrome. Objective To describe the epidemiological data of the ulnar nerve transposition surgical code in the treatment of CTS by the United Health System (SUS) from 2005 to 2015. Methodology This is a descriptive epidemiological study, in which data were obtained through consultation of the DATASUS database. Results/Discussion During this period, 774 procedures were performed and, despite the addition of 20.3 million people to the Brazilian population, the incidence was 0.33/ 1,000,000. National and international epidemiology point to a slightly higher prevalence of the procedure between men, in the fourth and fifth decades of life. Low permanence rate, as well as the absence of hospital deaths related to the procedure, infer that the procedure is safe, with low morbidity and mortality rates. Conclusion The annual incidence of the cubital syndrome submitted to surgical treatment at SUS in the Brazilian population was 1/7,670,833 in 2005 and½,174,468 in 2015. The cost of each surgical procedure during the same period ranged from R$ 318.88 to R$ 539.74. The mean hospitalization time for CTS surgery was 1.85 days.

Resting Tremor after Mild Head Injury: Case Report

Over the past few decades, it has been recognized that traumatic brain injury (TBI) may result in various movement disorders. However, moderate or mild TBI only rarely causes persistent post-traumatic movement disorders. In the present report, we describe a case of secondary tremor due to amild head injury with a transitory loss of consciousness. A 26- year-old man developed an isolated rest tremor of the hands and legs without other neurologic signs. The interval between the head trauma and the onset of the symptomswas 4 months. Neuroimaging studies reveled gliosis in the lentiform nucleus. Haloperidol administration resulted in tremor reduction. A rest tremor, similar to essential tremor, can be a rare complication of head trauma. Haloperidolmay be an effective and safe treatment modality for post-traumatic tremor. Further studies are needed to clarify the optimal drug for the treatment of post-traumatic tremor.

Síndrome compressiva de múltiplos nervos na dermatopolimiosite: relato de caso / Multiple Nerve Compression Syndrome in Dermatopolymyositis: Case Report

A dermatopolimiosite émiopatia inflamatória de etiologia provavelmente autoimune e comportamento heterogêneo, afetando principalmente pele e músculos e ocasionando manifestações exantemáticas características, como o eritema heliótropo e a pápula de Gottron, e fraqueza muscular proximal simétrica. A associação dessa patologia a neuropatias periféricas é pouco conhecida, podendo raramente ocorrer neuropatia múltipla. O objetivo deste artigo é relatar um caso de síndrome compressiva de múltiplos nervos em portador de dermatopolimiosite. O paciente apresentava fraqueza muscular proximal e exantema característico e foi submetido à revisão laboratorial, ressonância magnética de abdome e eletroneuromiografia, que mostraram alterações. Foi então tratado através da neurólise do nervo mediano ao nível do túnel do carpo e do nervo ulnar ao nível do túnel cubital. Trata-se de importante possibilidade terapêutica em casos como o descrito,mas estudos de maior porte sobre a descompressão simultânea dos túneis carpal e ulnar são necessários.

Dermatopolymyositis is an inflammatory myopathy ­ whose etiology is probably autoimmune ­ that has heterogeneous manifestations that occur mainly in skin and muscles and cause characteristic rash, such as heliotrope rash, Gottron's sign and symmetric proximal weakness. The association between this pathology and peripheral neuropathies is little known and multiple neuropathies rarely occur. The purpose of this article is to report a case of multiple nerve compression syndrome in a patient with dermatopolymyositis. The patient had proximal weakness and characteristic rash and underwent a laboratorial review, abdominal MRI and electromyography, which showed changes. So he was treated by neurolysis of median and ulnar nerves at carpal and cubital tunnels levels, respectively. It is an important therapeutic possibility in cases like this, but larger studies on simultaneous decompression of carpal and cubital tunnels are necessary.

Neuralgia occipital: relato de caso e revisão / Occipital Neuralgia: Case Report and Review

Neuralgia occipital (NO) é uma causa incomum de cefaleia caracterizada por dor paroxística, do tipo pontada, que se irradia para a região occipital. O objetivo deste artigo é relatar o caso de uma paciente com NO e descrever a técnica cirúrgica utilizada. O estudo compreende um levantamento bibliográfico para o conhecimento e melhor abordagem sobre o assunto. Com base na literatura, observa-se que a etiologia pode variar desde traumas, infecções, cirurgias de base de crânio, compressões de nervos ou vértebras até alterações degenerativas e anomalias congênitas. Porém, em sua maioria, os casos são idiopáticos. Apesar de o diagnóstico ser essencialmente clínico, é fundamental que sejam excluídos outros tipos de cefaleias primárias. De acordo com a gravidade e o tempo de evolução do caso, o tratamento da NO pode basear-se em bloqueios nervosos, medicamentos ­ como anti-inflamatórios não-esteroides e relaxantes musculares ­ ou cirurgias. Entre os procedimentos cirúrgicos disponíveis, encontram-se a descompressão do nervo occipital maior, ablação por radiofrequência e implantação de neuroestimulador.

Occipital Neuralgia (ON) is an uncommon cause of headache, characterized by paroxysmal pain, stabbing that radiates to occipital region. This article aims at reviewing the literature to the approach to the subject and performs the case report of patient who present with ON and underwent a surgical treatment. Based on the literature and analysis showed the etiologymay vary from trauma, infections, skull base surgery, compression of nerves or vertebrae to degenerative changes and congenital anomalies. However, most cases are idiopathic. Although the diagnosis is essentially clinical, it is essential that other types of primary headaches are excluded. According to severity and the time course of the case, the treatment of ON may be based on nerve blocks, medications like non-steroidal anti-inflammatory drugs and muscle relaxants. Surgical treatment for ON are nerve decompression, pulsed radiofrequency ablation and stimulator implantation.
