RESUMO

Despite treatment with levothyroxine, hypothyroidism and autoimmune thyroiditis (AIT) may be associated with reduced quality of life (QoL), an enigmatic condition referred to as "syndrome T". Peripheral neuropathy, described in untreated thyroid disease, could be a contributing mechanism. We analysed autonomic and somatosensory function in 29 patients with AIT and treated hypothyroidism and 27 healthy volunteers. They underwent heart rate variability (HRV) analysis and quantitative sensory testing (n = 28), comprising 13 parameters of small and large nerve fibre function and pain thresholds. Autonomic cardiovascular function was assessed in rest, deep respiration and orthostasis. Additionally, biomarkers for autoimmunity and thyroid function were measured. Anxiety, depression and QoL were assessed using validated questionnaires. 36% of the patients showed at least one sign of somatosensory small or large fibre dysfunction. 57% presented with mild hyperalgesia to at least one stimulus. Several markers of autonomic function and some detection thresholds were related to the antibody titres. Anxiety, depression scores and QoL correlated to antibody titres and HRV measures. Autonomic and somatosensory dysfunction indicate that in treated hypothyroidism and AIT a subgroup of patients suffers from neuropathic symptoms leading to impaired QoL. Additionally, mild hyperalgesia as a possible sensitisation phenomenon should be considered a target for symptomatic treatment.

RESUMO

Abstract Evidence has been reported that shows that somatosensory perception can be altered by a trigeminal injury resulting from maxillofacial surgical procedures. However, the surgical procedures that most frequently cause trigeminal lesions and the risk factors are unknown. In the same way, there is little information on what has been determined in preclinical models of trigeminal injury. This article integrates relevant information on trigeminal injury from both clinical findings and primary basic science studies. This review shows that the age and complexity of surgical procedures are essential to induce orofacial sensory alterations.


Resumen Se han reportado evidencias que demuestran que la percepción somatosensorial puede ser alterada por la lesión trigeminal producto de procedimientos quirúrgicos maxilofaciales. Sin embargo, se desconoce cuáles son los procedimientos quirúrgicos que más frecuentemente producen lesiones trigeminales, y los factores de riesgo. De la misma forma hay poca información sobre lo que se ha determinado en modelos preclínicos de lesión trigeminal. El objetivo de este artículo es integrar información relevante sobre la lesión trigeminal desde los hallazgos clínicos como los principales estudios de ciencia básica. Esta revisión demuestra que la edad y el tipo de procedimiento son fundamentales para inducir alteraciones sensoriales orofaciales, así como los procesos neurobiológicos que subyacen a estos padecimientos.

RESUMO

Introducción: la enfermedad por coronavirus del 2019 (COVID-19), causada por el nuevo coronavirus SARSCoV-2, se ha asociado con el desarrollo de enfermedades neurológicas como el síndrome de Guillain-Barré (SGB) y sus variantes. En el presente trabajo se reportan dos casos de síndromes desmielizantes asociados con la COVID-19. Casos clínicos: hombre de 53 años con SGB y mujer de 29 años con la variante del síndrome de Miller-Fisher (SMF), respectivamente. Ambos presentaron los signos y síntomas neurológicos clásicos de polineuropatía desmielinizante que caracterizan a estos síndromes. De las pruebas bioquímicas paraclínicas, el aumento de proteínas en líquido cefalorraquídeo fue distintiva. La positividad de la RT-qPCR para el SARS-CoV-2 indicó la asociación de los SGB y SMF con la COVID-19. Ambos pacientes se trataron con inmunoglobulina intravenosa y mostraron mejoría. La electromiografía realizada en semanas posteriores aún mostrabaafectación desmielinizante crónica. Conclusión: los casos de los SGB y SMF, junto con otros casos similares reportados en todo el mundo, proporcionan más evidencia para el SARS-CoV-2 como nueva posible etiología de estas raras enfermedades neurológicas.


Background: coronavirus disease 2019 (COVID-19), caused by the new coronavirus SARS CoV-2, has been associated with the development of neurological diseases such as Guillain-Barré syndrome (GBS) and its variants. In the present work, two cases of demyelinating syndromes associated with COVID-19 are reported. Clinical cases: 53-year-old male with GBS and and 29-yearold female with Miller-Fisher syndrome (MFS) variant, respectively. Both patients presented the classic neurological signs and symptoms of demyelinating polyneuropathy that characterizes the syndromes. From the paraclinical biochemical tests, the increase of proteins in cerebrospinal fluid was distinctive. The positivity of the RT-qPCR for SARSCoV-2 suggested the association of GBS and MFS with COVID-19. Both patients were treated with intravenous immunoglobulin showing improvement. Electromyography performed weeks ahead still showed chronic demyelinating involvement. Conclusion: The cases of GBS and MFS, along with other similar cases reported around the world, provide further evidence for SARS-CoV-2 as a new possible etiology of these rare neurological diseases.

RESUMO

Aim: Verify the accuracy of objective assessments compared to subjective tests in detecting changes in somatosensory perception in individuals affected by maxillofacial trauma. Methods: The review (PROSPERO n ° CRD42019125546) used the databases: MEDLINE, Cochrane, EMBASE, LILACS and other bibliographic resources. Prospective and retrospective studies that used objective and subjective methods of assessing facial sensitivity in maxillofacial fractures were included. There was no restriction on language or publication date. Risk of bias was assessed using the QUADAS-2. Data extraction and analysis were performed using a form developed for the study. Results: 21 studies were included. The clinical objective examination mainly includes assessments of: tactile sensitivity (95.24%) and nociceptive sensitivity (57.14%). The subjective assessment was based on the patient's report, spontaneously (61.90%), guided by structured questionnaires (33.33%) and/or using scales (9.52%) to measure the degree of impairment. In risk of bias assessment, were observed no adequate interpretation and classification of changes in subjective sensitivity, subject to inappropriate analysis of the data. In addition, the studies bring several instruments without standardization for assessing sensory modalities. Conclusion: The objective assessment is a complement to the subjective assessment, using the touch assessment as the main parameter in the profile of the facial peripheral integrity, associated or not with nociceptive assessment. Lack of consensus on the indication of specific instruments for testing is a limiting factor. Thus, based on the studies, is proposed a minimum battery of sensitivity assessment to obtain an overview of the patient's peripheral nervous situation

RESUMO

ATP-dependent P2X3 receptors play a crucial role in the sensitization of nerve fibers and pathological pain pathways. They are also involved in pathways triggering cough and may contribute to the pathophysiology of endometriosis and overactive bladder. However, despite the strong therapeutic rationale for targeting P2X3 receptors, preliminary antagonists have been hampered by off-target effects, including severe taste disturbances associated with blocking the P2X2/3 receptor heterotrimer. Here we present a P2X3 receptor antagonist, eliapixant (BAY 1817080), which is both highly potent and selective for P2X3 over other P2X subtypes in vitro, including P2X2/3. We show that eliapixant reduces inflammatory pain in relevant animal models. We also provide the first in vivo experimental evidence that P2X3 antagonism reduces neurogenic inflammation, a phenomenon hypothesised to contribute to several diseases, including endometriosis. To test whether eliapixant could help treat endometriosis, we confirmed P2X3 expression on nerve fibers innervating human endometriotic lesions. We then demonstrate that eliapixant reduces vaginal hyperalgesia in an animal model of endometriosis-associated dyspareunia, even beyond treatment cessation. Our findings indicate that P2X3 antagonism could alleviate pain, including non-menstrual pelvic pain, and modify the underlying disease pathophysiology in women with endometriosis. Eliapixant is currently under clinical development for the treatment of disorders associated with hypersensitive nerve fibers.

RESUMO

Nociplastic pain is the semantic term suggested by the international community of pain researchers to describe a third category of pain that is mechanistically distinct from nociceptive pain, which is caused by ongoing inflammation and damage of tissues, and neuropathic pain, which is caused by nerve damage. The mechanisms that underlie this type of pain are not entirely understood, but it is thought that augmented CNS pain and sensory processing and altered pain modulation play prominent roles. The symptoms observed in nociplastic pain include multifocal pain that is more widespread or intense, or both, than would be expected given the amount of identifiable tissue or nerve damage, as well as other CNS-derived symptoms, such as fatigue, sleep, memory, and mood problems. This type of pain can occur in isolation, as often occurs in conditions such as fibromyalgia or tension-type headache, or as part of a mixed-pain state in combination with ongoing nociceptive or neuropathic pain, as might occur in chronic low back pain. It is important to recognise this type of pain, since it will respond to different therapies than nociceptive pain, with a decreased responsiveness to peripherally directed therapies such as anti-inflammatory drugs and opioids, surgery, or injections.

RESUMO

Studies from our lab demonstrated that 1 × 105 intra-arterial mesenchymal stem cells (IA MSCs) at 6 h following ischemic stroke are efficacious owing to its maximum homing due to elevated stromal derived factor 1 (SDF1) in the tissue. Further, IA MSCs could abate the infarct progression, improve functional outcome, and decrease expression of calcineurin by modifying neuronal Ca2+ channels following ischemic stroke. Since stroke pathology also encompasses acidosis that worsens the condition; hence, the role of acid sensing ion channels (ASICs) in this context could not be overlooked. ASIC1a being the major contributor towards acidosis triggers Ca2+ ions overload which progressively contributes towards exacerbation of neuronal injury following ischemic insult. Inflammasome involvement in ischemic stroke is well reported as activated ASIC1a increases the expression of inflammasome in a pH-dependent manner to trigger inflammatory cascade. Hence, the current study aimed to identify if IA MSCs can decrease the production of inflammasome by attenuating ASIC1a expression to render neuroprotection. Ovariectomized Sprague Dawley (SD) rats exposed to middle cerebral artery occlusion (MCAo) for 90 min were treated with phosphate-buffered saline (PBS) or 1 × 105 MSCs IA at 6 h to check for the expression of ASIC1a and inflammasome in different groups. Inhibition studies were carried out to explore the underlying mechanism. Our results demonstrate that IA MSCs improves functional outcome and oxidative stress parameters, and decreases the expression of ASIC1a and inflammasomes in the cortical brain region after ischemic stroke. This study offers a preliminary evidence of the role of IA MSCs in regulating inflammasome by modulating ASIC1a.

RESUMO

The Cheiro-Oral (COS) Syndrome is a rare neurologic condition characterized by sensory disturbances involving the peri-oral area and the upper extremity, typically isolated to the hand or fingers. The thalamus contralateral to the symptomatic side is the brain region most commonly involved. Most cases are caused by ischemic or hemorrhagic strokes, although other structural lesions have been implicated. These include tumors, subdural hematomas, aneurysms, and infections. The unusual and seemingly unrelated nature of the symptoms may contribute to misdiagnosis and incomplete workup for potentially serious conditions. We are unable to identify a report of this condition in the emergency medicine literature despite the emergency department being the likely point of presentation for patients with COS. In this report, we describe two patients with COS who presented to our emergency department and review the features of COS as described in published case reports.

RESUMO

ABSTRACT Purpose: to evaluate the occurrence of loss of sensitivity of the inferior alveolar nerve, and to monitor the remission of this change in patients with mandibular fractures subjected to surgical treatment. Methods: patients with mandibular fractures, surgically treated within one year, were prospectively evaluated. Data regarding etiology, fracture location, type and displacement, and surgical access, were obtained. The tactile and thermal tests were applied at eighteen points in the mental region, within a period of six months. Statistical tests were applied to compare the categories of variables and the period of observation (p ≤ 0.050). Results: during the study, 37 patients were included. There were 24 bilateral and 13 unilateral fractures. Sensory changes occurred in 56.8% of the patients in the preoperative period, in 83.8% of the patients, in the postoperative period, and 35.1% of the patients presented complete remission during the final period of the study. Conclusion: sensory changes occurred in about half of the patients, due to the fracture, increasing greatly in the postoperative period, with complete remission in about one third of the cases. The fracture type, degree of displacement and surgical access type influenced the occurrence of sensory alterations.

RESUMO

Arterial gas embolism is a well-described and frequently seen injury encountered in both civilian and military diving operations. It is becoming increasingly reported and potentially increasingly more common in the hospital environment as a complication of more frequent gastroenterology procedures. We present a case of a 49-year-old, active-duty female who developed significant left-sided neurological deficits manifesting as diffuse left-sided weakness, subjective confusion, and severe headache following esophagogastroduodenoscopy. With increased clinical suspicion for arterial gas embolism, the patient was evaluated by the hyperbaric medicine team at our facility and subsequently treated to near-resolution of symptoms by multiple hyperbaric oxygen treatments. This case highlights the importance of considering this rare complication during or following common invasive procedures. Furthermore, the unique training and experience of physicians with expertise in diving medicine and their ability to recognize these types of injury in the hospital setting highlights the importance of continued training in these fields within Military Medicine in addition to civilian Undersea and Hyperbaric Medicine fellowships.

RESUMO

PURPOSE OF REVIEW: Neuroanatomic localization and pattern recognition can be used to diagnose both focal lesions and generalized disorders of the peripheral nervous system. This article describes the nature and pattern of sensory and motor deficits associated with lesions of specific spinal nerve roots, plexus, or peripheral nerves. It also describes the patterns of sensory and motor deficits that suggest multifocal or generalized disorders of the motor neurons, sensory neurons, and peripheral nerves. RECENT FINDINGS: The pattern of sensory and motor deficits may be used to distinguish lesions of the peripheral nervous system from those of the central nervous system. The spinal roots, nerve plexus, and peripheral nerves supply specific muscles and receive sensory input from distinctive cutaneous regions. Focal lesions of these structures therefore produce characteristic patterns of sensory and motor deficits. Multifocal or generalized disorders of the peripheral nervous system may be distinguished by categorizing their sensory and motor involvement, proximal and distal predominance, and degree of symmetry. Serum tests, CSF analysis, electrodiagnostic studies, MRI, ultrasound, nerve biopsy, and skin biopsy have unique roles in the diagnosis of suspected neuromuscular disorders. SUMMARY: A structured approach to the diagnosis of nerve and motor neuron disorders can lead to hypothesis-driven diagnostic testing. Ancillary tests should be reserved for cases in which confirming or refuting a diagnosis will change patient management.

RESUMO

BACKGROUND: Traditionally, S1 transforaminal epidural steroid injection (TFESI) has been performed using an anteroposterior (AP) fluoroscopic view. In 2007, the oblique "Scotty dog" (OS) approach was introduced as an alternative technique. We compared passage time of the needle into S1 foramen (Tf) between the anteroposterior (AP) and oblique "Scotty dog" (OS) approach during S1 TFESI. METHODS: In this prospective randomized controlled trial, seventy patients scheduled S1 TFESI were randomly allocated into AP or OS groups. In the AP group, a slight cephalad-caudad tilt was used. In the OS group, the C-arm was rotated ipsilateral oblique degrees to view the S1 Scotty dog. Both groups received injection of steroid mixed with local anesthetics. We measured the passage time of the needle into S1 foramen (Tf), primary outcome, and total procedure time (Tt) between the groups. We also recorded presence of intravascular injection, patients-assessed pain relief for one month and complications. RESULTS: The Tf and Tt were shorter in the OS than in the AP group (24.4 ±â€Š24.0 s vs 47. 8 ±â€Š53.2seconds; 93.3 ±â€Š35.0 seconds vs 160.0 ±â€Š98.7 seconds, P < .001, both). Incidence of intravascular injection (AP, 8 [22.8%]; OS, 4 [11.4%], P = .205), pain score, and complication rates were not statistically different between the two groups. In logistic regression analysis, the body mass index (BMI) was a risk factor for longer Tt (odds ratio [OR] = 1.27, 95% CI: 1.02-1.58, P = .030). CONCLUSION: The passage time of the needle into S1 foramen was shorter in OS approach and the OS approach reduced the procedure time compared with the AP approach during S1 TFESI. The practitioners should note that procedure time can be prolonged in obese patients.

RESUMO

BACKGROUND AND PURPOSE: Research suggests that women and men may present with different transient ischemic attack (TIA) and stroke symptoms. We aimed to explore symptoms and features associated with a definite TIA/stroke diagnosis and whether those associations differed by sex. METHODS: We completed a retrospective cohort study of patients referred to The Ottawa Hospital Stroke Prevention Clinic in 2015. Exploratory multinomial logistic regression was used to evaluate candidate variables associated with diagnosis and patient sex. Backwards elimination of the interaction terms with a significance level for staying in the model of 0.25 was used to arrive at a more parsimonious model. RESULTS: Based on 1770 complete patient records, sex-specific differences were noted in TIA/stroke diagnosis based on features such as duration of event, suddenness of symptom onset, unilateral sensory loss, and pain. CONCLUSIONS: This preliminary work identified sex-specific differences in the final diagnosis of TIA/stroke based on common presenting symptoms/features. More research is needed to understand if there are biases or sex-based differences in TIA/stroke manifestations and diagnosis.

RESUMO

Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 and chemosensory impairments, such as anosmia. However, these reports have downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, and generally lacked quantitative measurements. Here, we report the development, implementation, and initial results of a multilingual, international questionnaire to assess self-reported quantity and quality of perception in 3 distinct chemosensory modalities (smell, taste, and chemesthesis) before and during COVID-19. In the first 11 days after questionnaire launch, 4039 participants (2913 women, 1118 men, and 8 others, aged 19-79) reported a COVID-19 diagnosis either via laboratory tests or clinical assessment. Importantly, smell, taste, and chemesthetic function were each significantly reduced compared to their status before the disease. Difference scores (maximum possible change ±100) revealed a mean reduction of smell (-79.7 ± 28.7, mean ± standard deviation), taste (-69.0 ± 32.6), and chemesthetic (-37.3 ± 36.2) function during COVID-19. Qualitative changes in olfactory ability (parosmia and phantosmia) were relatively rare and correlated with smell loss. Importantly, perceived nasal obstruction did not account for smell loss. Furthermore, chemosensory impairments were similar between participants in the laboratory test and clinical assessment groups. These results show that COVID-19-associated chemosensory impairment is not limited to smell but also affects taste and chemesthesis. The multimodal impact of COVID-19 and the lack of perceived nasal obstruction suggest that severe acute respiratory syndrome coronavirus strain 2 (SARS-CoV-2) infection may disrupt sensory-neural mechanisms.

RESUMO

OBJECTIVE: Spinal involvement in neurocysticercosis is rare and can lead to debilitating injury if not diagnosed and treated early. We aim to provide the reader with a thorough analysis of the best available evidence regarding patient characteristics, optimal treatment modality, and outcomes in cases of spinal neurocysticercosis. METHODS: A systematic review of the literature using PubMed, Google Scholar, and Web of Science electronic databases was made according to the PRISMA guidelines. An illustrative case of intramedullary-cervical spinal disease is also presented for illustrative purposes. RESULTS: A total of 46 reports of 103 patients fitting the screening criteria were identified. Isolated spinal involvement was seen in 46.15% of patients. Most infections (76.92%) had an intradural extramedullary localization, with 43.27% of cases involving >1 spinal cord level. The most common presenting symptoms were motor deficits (77.88%), pain syndromes (64.42%), and sensory deficits (53.85%). Combined surgical resection and pharmacologic therapy was the most frequently used treatment modality (49.04%) and had the highest proportion of patients reporting symptomatic improvement at follow-up (78.43%). Combination therapy had a significantly higher rate of neurologic recovery compared with surgery alone (P = 0.004) or medical treatment (P = 0.035). CONCLUSIONS: Spinal involvement in neurocysticercosis should be considered in patients from or who traveled to endemic areas presenting with ring-enhancing lesions. Combined treatment with surgery followed by cysticidal and steroid medication seems to be superior to surgery or medical treatment in isolation and seems to provide the highest chances of recovery.

RESUMO

OBJECTIVE: To investigate the clinicopathologic features of eosinophilic granulomatosis with polyangiitis (EGPA)-associated neuropathy with a focus on the presence or absence of anti-neutrophil cytoplasmic antibodies (ANCAs). METHODS: We examined the clinical features and pathologic findings of sural nerve biopsy specimens from 82 patients with EGPA-associated neuropathy. Of these patients, 32.9% were myeloperoxidase (MPO)-ANCA positive, and 67.1% were MPO-ANCA negative. PR3-ANCA was negative in all of 78 examined patients. RESULTS: Upper limb symptoms were more frequently reported as initial neuropathic manifestations in the MPO-ANCA-positive group than in the MPO-ANCA-negative group (44.4% vs 14.6%, p < 0.01). The serum levels of C-reactive protein were significantly higher in the MPO-ANCA-positive group than in the MPO-ANCA-negative group (p < 0.05). Sural nerve biopsy specimens showed findings suggestive of vasculitis (i.e., destruction of vascular structures) in epineurial vessels; these results were seen more frequently in the MPO-ANCA-positive group than in the MPO-ANCA-negative group (p < 0.0001). Conversely, the numbers of eosinophils in the lumen of the epineurial vessels (p < 0.01) and epineurial vessels occluded by intraluminal eosinophils (p < 0.05) were higher in the MPO-ANCA-negative group than in the MPO-ANCA-positive group. Furthermore, the incidence of eosinophil infiltration in the endoneurium was higher in the MPO-ANCA-negative group than in the MPO-ANCA-positive group (p < 0.01). CONCLUSIONS: This study suggests that the pathogenesis of EGPA comprises at least 2 distinct mechanisms: ANCA-associated vasculitis resulting in ischemic effects and inflammation, which is prominent in MPO-ANCA-positive patients, and eosinophil-associated vascular occlusion leading to ischemia and eosinophil-associated tissue damage, which is conspicuous in MPO-ANCA-negative patients.

RESUMO

OBJECTIVE: In the healthy spine, the spinal cord moves unimpeded with spinal fluid pulsation in the rostral and caudal directions. When a portion of the spinal cord becomes attached to lesions within the spinal column, excess strain can cause signs and symptoms such as pain, motor deficits, sensory deficits, bladder dysfunction, and bowel dysfunction. This condition is termed tethered cord syndrome. There are no clear guidelines for offering surgical intervention, although there is a general consensus that worsening signs and symptoms increase the likelihood that patients will need surgery. METHODS: In this article, we conduct a systematic review and meta-analysis for all available literature within the Ovid (MEDLINE), PubMed, and Google Scholar databases to evaluate common symptoms among patients with tethered cord and to examine how surgery affects symptoms. RESULTS: Within the cohort of 730 patients, 708 (97%) were treated surgically by a detethering procedure. The most common preoperative sign or symptom was pain (81%), followed by motor deficits (63%), sensory deficits (61%), bladder dysfunction (56%), and bowel dysfunction (15%). One percent of patients had no deficit or symptom. Pain was the symptom that was most responsive to surgery, with 81% of patients reporting that their pain improved after detethering. CONCLUSIONS: Tethered cord syndrome should be included in the differential diagnosis in patients presenting with back or leg pain, somatosensory symptoms of the lower extremities, muscular weakness, urodynamic dysfunction, or bowel dysfunction. After a definitive diagnosis is made, patients should be counseled about surgical detethering as an option.

RESUMO

ABSTRACT Although it is known that anxiety and depressive disorders frequently accompany migraine and TTH, the role of somatic amplification (SSA) and health anxiety in these diseases is not adequately known. Objective: The aim of this study is to compare SSA and health anxiety in patients with migraine or TTH, and healthy controls and to investigate the relationships between SSA, health anxiety, headache characteristics, anxiety and depressive symptoms. Methods: Fifty-four migraine, 50 TTH patients from the outpatient unit of the neurology department and 53 healthy volunteers were recruited for the study. The somatosensory amplification scale (SSAS), health anxiety inventory, Beck depression (BDI) and anxiety inventory (BAI) were administered to all participants. Results: The SSAS scores were significantly higher in migraineurs compared with the healthy controls. The health anxiety scores were significantly higher in both migraine and TTH groups. The BDI and BAI scores were also significantly higher in migraine and TTH groups compared with the controls. A significant positive correlation was found between headache frequency and BAI scores, the visual analogue scale scores and SSAS and BDI scores in migraineurs. The SSAS scores were also significantly correlated with the BDI and BAI scores in both of the headache groups. A similar correlation was determined with the health anxiety scores. Conclusions: While patients with migraine and TTH evalute, taking into account the SSA and health anxiety may contribute to the prognosis and treatment of these diseases.


RESUMO Embora se saiba que os distúrbios de ansiedade e depressão frequentemente acompanhem a enxaqueca e a TTH, o papel da amplificação somatossensorial (somatosensory amplification, SSA) e da hipocondria nessas doenças ainda não é bem conhecido. Objetivo: O presente estudo faz uma comparação entre pacientes que sofrem de enxaqueca e TTH com um grupo de controle saudável em termos de SSA e hipocondria e investiga a relação entre os achados e as características da cefaleia, a ansiedade e os sintomas depressivos. Métodos: O estudo incluiu 54 pacientes com enxaqueca, 50 pacientes com TTH e 53 voluntários saudáveis que se cadastraram na clínica de neurologia. A escala de amplificação somatossensorial (somatosensory amplification scale, SSAS), o inventário de hipocondria, o Inventário de Depressão de Beck (Beck Depression Inventory, BDI) e o Inventário de Ansiedade de Beck (Beck Anxiety Inventory, BAI) foram aplicados aos participantes. Resultados: Quando comparados com os controles saudáveis, as pontuações da SSAS dos pacientes com enxaqueca foram significativamente maiores, enquanto as pontuações de hipocondria foram significativamente maiores em ambos os grupos de enxaqueca e TTH. As pontuações do BAI e do BDI foram significativamente maiores em ambos os grupos de pacientes que no grupo de controle. No grupo da enxaqueca, foi identificada uma correlação positiva entre frequência de cefaleia e ansiedade, bem como entre a Escala Analógica Visual (EVA), a SSAS e a depressão. Em ambos os grupos de pacientes, a SSA foi correlacionada positivamente com a depressão e a ansiedade, e uma correlação semelhante foi encontrada entre a SSA e a hipocondria. Conclusão: Em avaliações dessas doenças, a hipocondria e a SSA devem ser levadas em consideração, pois se acredita que essa abordagem possa contribuir positivamente para o prognóstico e tratamento da doença.

RESUMO

FUNDAMENTO: A estesiometria é um teste quantitativo para avaliar o desempenho tátil sensorial, verificar o grau de sensibilidade cutânea por meio dos monofilamentos de nylon ao toque leve e à pressão. OBJETIVO: Verificar a utilização dos monofilamentos como instrumento de avaliação da sensibilidade de pacientes com sequela de AVE na literatura. MÉTODO: Estudo de revisão sistemática, realizado com artigos indexados na base de dados PubMed, Lilacs e Scielo, sem limitação por data de publicação, sendo a busca realizada no mês de outubro de 2018. RESULTADOS: Foram elencados dezessete estudos, após análise destes, nove foram excluídos por não preencherem os critérios de inclusão, e oito foram lidos na íntegra. Após leitura dos artigos, foram obtidos os dados referentes a: número da amostra, instrumentos de avaliação, se houve ou não intervenção, e a conclusão do estudo. CONCLUSÃO: Por mais promissor que seja o uso dos monofilamentos para avaliação sensorial, esta revisão mostrou que existem poucos estudos avaliando os pacientes com sequela de AVE com este método de avaliação, principalmente estudos clínicos.


BACKGROUND:The esthesiometry is a quantitative test to evaluate the tactile sensory performance, to verify the degree of cutaneous sensitivity through nylon monofilaments to light touch and pressure. OBJECTIVE: To verify the use of monofilaments as a tool to assess the sensitivity of patients with a sequel to stroke in the literature. METHOD: A systematic review study was carried out with articles indexed in the PubMed, Lilacs and Scielo database, without limitation by date of publication. The search was carried out in October 2018. RESULTS: Seventeen studies were analyzed, after analyzing nine were excluded because they did not meet the inclusion criteria, and eight were read in full. After reading the articles, data were obtained regarding: sample number, evaluation instruments, whether or not there was intervention, and the conclusion of the study. CONCLUSION: As promising as it may be the use of monofilaments for sensory evaluation, this review showed that there are few studies evaluating patients with sequelae of stroke with this method of evaluation, mainly clinical studies.
