Vascular loops mimicking herniated lumbar discs: fair warning.

The authors report their experience with twenty-one consecutive patients who presented with symptoms and imaging characteristics of a herniated lumbar disc; of whom, at the time of surgery had a vascular loop instead. The procedure was performed on 14 women and seven men with a mean age of 39 years. Clinical complaints included lumbar aching with one limb overt radiculopathy in all patients; with additional sphincter dysfunction in two cases. Symptoms had developed within a mean period of three months. In all patients, the disc was exposed through an L5-S1 (n = 10); L4-L5 (n = 5) and L3-L4 (n = 6) open minimal laminotomy. In 16 patients, rather than a herniated disc they had a lumbar epidural varix, while an arterio-venous fistula was found in the remaining five cases. In all cases, the vascular disorder was resected and its subjacent disc was left intact. One patient had a postoperative blood transfusion. While the radiculopathy dysfunction improved in all patients, four patients reported lasting lumbar pain following surgery. The postoperative imaging confirmed the resolution of the vascular anomaly and an intact disc. The mean length of the follow-up period was 47 months. Either epidural varix or arterio-venous fistula in the lumbar area may mimic a herniated disc on imaging studies. With the usual technique they can be operated safely. Resection of the anomaly can be sufficient for alleviating radiculopathy symptoms.

The diagnostic accuracy of infrared thermography in lumbosacral radicular pain: a prospective study.

BACKGROUND: To identify the sensitivity, specificity, and overall diagnostic accuracy of infrared thermography in diagnosing lumbosacral radicular pain. METHODS: Patients sequentially presenting with lower extremity pain were enrolled. A clinical certainty score ranging from 0 to 10 was used to assess the likelihood of lumbosacral radicular pain, with higher scores indicating higher likelihood. Infrared Thermography scans were performed and the temperature difference (ΔT) was calculated as ΔT = T1 - T2, where T2 represents the skin temperature of the most painful area on the affected limb and T1 represents the skin temperature of the same area on the unaffected limb. Upon discharge from the hospital, two independent doctors diagnosed lumbosacral radicular pain based on intraoperative findings, surgical effectiveness, and medical records. RESULTS: A total of 162 patients were included in the study, with the adjudicated golden standard diagnosis revealing that 101 (62%) patients had lumbosacral radicular pain, while the lower extremity pain in 61 patients was attributed to other diseases. The optimal diagnostic value for ΔT was identified to fall between 0.8℃ and 2.2℃, with a corresponding diagnostic accuracy, sensitivity, and specificity of 80%, 89%, and 66% respectively. The diagnostic accuracy, sensitivity, and specificity for the clinical certainty score were reported as 69%, 62%, and 79% respectively. Combining the clinical certainty score with ΔT yielded a diagnostic accuracy, sensitivity, and specificity of 84%, 77%, and 88% respectively. CONCLUSION: Infrared thermography proves to be a highly sensitive tool for diagnosing lumbosacral radicular pain. It offers additional diagnostic value in cases where general clinical evaluation may not provide conclusive results. TRIAL REGISTRATION: ChiCTR2300078786, 19/22/2023.

Neurophysiological Assessment of H-Reflex Alterations in Compressive Radiculopathy.

This study aimed to investigate changes in the H-reflex recruitment curve in compressive radiculopathy, specifically assessing differences between symptomatic and asymptomatic limbs in patients with unilateral S1 radiculopathy through derived parameters. A total of 24 volunteers (15 male and 9 female, aged between 22 and 60 years) with confirmed nerve root compression in the L5/S1 segment participated. Nerve root compression was verified through clinical MRI examination and attributed to disc protrusion, spinal canal stenosis, or isthmic spondylolisthesis of L5/S1. Analysis revealed no difference in M-wave threshold intensity between symptomatic and non-symptomatic limbs. However, the H-reflex exhibited a trend toward increased threshold intensity in the symptomatic limb. Notably, a significant decrease in the slope of the H-reflex was observed on the symptomatic side, and the maximal H-reflex amplitude proved to be markedly different between the two limbs. The Hmax/Mmax ratio demonstrated a significant decrease in the symptomatic limb, indicating reduced effectiveness of signal translation. In conclusion, our findings emphasize the importance of H-reflex parameters in evaluating altered recruitment curves, offering valuable insights for neurological examinations. The observed differences in maximal values of M-wave, H-reflex, and their ratio in affected and unaffected limbs can enhance the diagnostic process for lumbosacral unilateral radiculopathy and contribute to a standardized approach in clinical assessments.

Neurologic Approach to Radiculopathy, Back Pain, and Neck Pain.

Back pain and neck pain are common in clinical practice, but significant challenges and pitfalls exist in their diagnosis, treatment, and management. From the neurologic standpoint, cervical radiculopathy and lumbosacral radiculopathy are characterized by neck pain or back pain accompanied by sensory and motor symptoms in an arm or leg. The basic neurologic examination is vital, but testing like electromyography and MRI is often needed especially in cases that fail conservative management. Oral medications, injection-based therapies, physical therapy, and surgical evaluation all have a place in the comprehensive neurologic management of back and neck pain and associated radiculopathy.

A novel simultaneous three-dimensional volumetric morphological imaging and T2-mapping method, multi-interleaved X-prepared turbo-spin echo with intuitive relaxometry provides more accurate quantification of cervical spinal nerves.

PURPOSE: MIXTURE is a simultaneous morphological and quantitative imaging sequence developed by Philips that provides high-resolution T2 maps from the imaged series. We aimed to compare the T2 maps of MIXTURE and SHINKEI-Quant (S-Q) in the cervical spine and to examine their usefulness in the functional diagnosis of cervical radiculopathy. METHODS: Seven healthy male volunteers (mean age: 31 ± 8.0 years) and one patient with cervical disc herniation (44 years old, male) underwent cervical spine magnetic resonance imaging (MRI), and T2-mapping of each was performed simultaneously using MIXTURE and S-Q in consecutive sequences in one imaging session. The standard deviation (SD) of the T2 relaxation times and T2 relaxation times of the bilateral C6 and C7 dorsal root ganglia (DRG) and C5/6 level cervical cord on the same slice in the 3D T2-map of the cervical spine coronal section were measured and compared between MIXTURE and S-Q. RESULTS: T2 relaxation times were significantly shorter in MIXTURE than in S-Q for all C6, C7 DRG, and C5/6 spinal cord measurements. The SD values of the T2 relaxation times were significantly lower for MIXTURE in the C5/6 spinal cord and C7 DRG. In cervical disc herniation, MRI showed multiple intervertebral compression lesions with spinal canal stenosis at C5/6 and disc herniation at C6/7. CONCLUSION: MIXTURE is useful for preoperative functional diagnosis. T2-mapping using MIXTURE can quantify cervical nerve roots more accurately than the S-Q method and is expected to be clinically applicable to cervical radiculopathy.

Vitamin B12 deficiency presenting as neck pain and cervical radiculopathy.

Vitamin B12 is required for the formation of haematopoietic cells and the synthesis of myelin. Deficiency typically presents with fatigue and megaloblastic anaemia. Prolonged deficiency can cause neurological symptoms such as paresthesia, which can progress to subacute combined degeneration of the spinal cord. We describe an unusual presentation of B12 deficiency in a young man who was initially diagnosed and treated for cervical radiculopathy. This case highlights the challenges of diagnosing B12 deficiency in patients with neurologic but without haematologic, abnormalities. While the current incidence of B12 deficiency in developed countries is low, cases are likely to rise with the increased adoption of veganism. Clinicians should be aware of the variable presentations of B12 deficiency because delayed diagnosis and treatment increases morbidity and can cause irreversible neurological deficits.

The Diagnostic Role of Adding the Hoffman Reflex for L5 Radiculopathy in the Electrodiagnostic Laboratory: A Cross-sectional Study.

OBJECTIVES: To investigate changes in the H-reflex in patients with monoradiculopathies involving L5 or S1 levels by stimulating the sciatic nerve and recording simultaneously from the tibialis anterior (TA), peroneus longus (PL), and soleus (S) muscles. METHODS: Patients with unilateral radicular back pain with L5 or S1 root compression on MRI, participated in this cross-sectional study. The H-reflex over the TA, PL, and S muscles was simultaneously recorded by sciatic nerve stimulation. The H-reflex latency was compared with that of the contralateral extremity. RESULTS: Fifty-eight patients (29 patients L5; 29 patients S1 radiculopathy) were included in the study. There were significant delays in the latency of the H-reflex over TA (30.95±2.31-29.21±1.4) and PL (31.05±2.85-29.02±1.99) muscles on the affected side in patients with L5 radiculopathy. However, the latency of the S H-reflex was similar on both sides. In contrast, in patients with S1 radiculopathy, there was a significant delay in the latency of soleus H reflex (32.76±3.45-29.9±3.19), while the significant delay was not detected in the TA and PL muscles. However, the cutoff values for the H-reflex latency of all muscles were not found to have clinical significance. CONCLUSIONS: The study presents that the H-reflex study, recorded from the TA, PL, and S muscles by sciatic nerve stimulation, is of interest but has minimal contribution to radiculopathy diagnosis in conventional electrodiagnostic tests.

A clinical audit of the Emergency Department: Doctors' opinions on the diagnosis and management of cervical spine radiculopathy.

OBJECTIVE: A clinical audit was carried out on the opinions of doctors working in the Emergency Department (ED) of a large urban hospital regarding the diagnosis and management of cervical spine radiculopathy (CSR). Using international guidelines and current research, it aimed to determine if patients attending this ED were diagnosed and managed in line with best practice, and to identify any discrepancies or areas for improvement in relation to this. METHOD: Doctors working in this ED were sent an online questionnaire and descriptive analysis was performed on the results to ascertain how they diagnose and manage patients who present with symptoms of CSR. It covered; presentation and definitions of CSR, identification of red flags, clinical tests used, diagnostic test criteria, appropriate management, education and advice given, and the criteria for further management. Additionally, it looked at their opinion on the services' needs. RESULTS: Most agreed that CSR will improve within 4 weeks with non-operative management; however, there was a lack of consensus regarding the most affected nerve root, differential diagnosis and appropriate diagnostic tests. Opinions aligned regarding the identification of red flags and early management, especially with widespread neurological deficits. However, the management of ongoing pain or new neurological signs, differed between clinicians. Most participants strongly agreed that access to MRIs affected referrals within an ED episode. CONCLUSION: Overall, the opinions matched recommended guidelines; however, some gaps in knowledge and differing management approaches were identified, indicating the need for ongoing education and standardisation of management.

The immediate effect of cervical rotation-traction manipulation on cervical paravertebral soft tissue: a study using soft tissue tension cloud chart technology.

BACKGROUND: To evaluate the reliability of the Soft Tissue Tension Cloud Chart (STTCC) technology, an original method combining multi-point Cervical Paravertebral Soft Tissue Test (CPSTT) with MATLAB software, we conducted a preliminary analysis on the immediate effects of Orthopaedic Manual Therapy (OMT) on cervical paravertebral soft tissue. METHODS: 30 patients with Cervical Spondylotic Radiculopathy (CSR) were included in this study. We analyzed the differences in CPSTT before and after treatment with Cervical Rotation-Traction Manipulation (CRTM), a representative OMT technique in Traditional Chinese Medicine, using the STTCC technology. RESULTS: The STTCC results demonstrated that post-treatment CPSTT levels in CSR patients were significantly lower than pre-treatment levels after application of CRTM, with a statistically significant difference (P < 0.001). Additionally, pre-treatment CPSTT levels on the symptomatic side (with radicular pain or numbness) were higher across the C5 to C7 vertebrae compared to the asymptomatic side (without symptoms) (P < 0.001). However, this difference disappeared after CRTM treatment (P = 0.231). CONCLUSIONS: The STTCC technology represents a reliable method for analyzing the immediate effects of OMT. CSR patients display uneven distribution of CPSTT characterized by higher tension on the symptomatic side. CRTM not only reduces overall cervical soft tissue tension in CSR patients, but can also balance the asymmetrical tension between the symptomatic and asymptomatic sides. TRIAL REGISTRATION: This study was approved by the Chinese Clinical Trials Registry (Website: . https://www.chictr.org.cn .) on 20/04/2021 and the Registration Number is ChiCTR2100045648.

Age and flexors as risk factors for cervical radiculopathy: A new machine learning method.

This study aimed to investigate the risk factors for cervical radiculopathy (CR) along with identifying the relationships between age, cervical flexors, and CR. This was a retrospective cohort study, including 60 patients with CR enrolled between December 2018 and June 2020. In this study, we measured C2 to C7 Cobb angle, disc degeneration, endplate degeneration, and morphology of paraspinal muscles and evaluated the value of predictive methods using receiver operating characteristic curves. Next, we established a diagnostic model for CR using Fisher discriminant model and compared different models by calculating the kappa value. Age and cervical flexor factors were used to construct clinical predictive models, which were further evaluated by C-index, receiver operating characteristic curve, calibration curve, and decision curve analysis. Multivariate analysis showed that age and cervical flexors were potential risk factors for CR, while the diagnostic model indicated that both exerted the best diagnostic effect. The obtained diagnostic equation was as follows: y1 = 0.33 × 1 + 10.302 × 2-24.139; y2 = 0.259 × 1 + 13.605 × 2-32.579. Both the C-index and AUC in the training set reached 0.939. Moreover, the C-index and AUC values in the external validation set reached 0.961. We developed 2 models for predicting CR and also confirmed their validity. Age and cervical flexors were considered potential risk factors for CR. Our noninvasive inspection method could provide clinicians with a more potential diagnostic value to detect CR accurately.

Self-reported Measures of Function Compared to Lower Limb Motor Performance in People With and Without Imaging Evidence of Unilateral Lumbar Nerve Root Compression: A Cross-sectional Study.

OBJECTIVE: The primary objective of the present study was to determine if imaging findings of unilateral lumbar nerve root compression (ULNRC) impact performance on a coordinated motor performance task and to determine if there were correlations between motor performance and self-reported clinical measures. METHODS: People with back pain (N = 45) were stratified into 3 groups based on combinations of: lumbar imaging; and clinical presentation for ULNRC. Group 1 included people with imaging of lumbar nerve root compression, who presented with neurological deficit. Group 2 people demonstrated imaging evidence of nerve compression, without motor, sensory or reflex change. Group 3 participants possessed only degenerative changes on lumbar imaging films, and were neurologically intact. Performance measures included behavioral and kinematic variables from an established lower limb Fitts' Task requiring movements to targets of different difficulties. Self-reported measures of disability, function and pain were collected. Analysis of variance for between and within group variables were conducted, and Pearson correlation compared performance with self-reported measures. RESULTS: All groups yielded main effects for movement time with increasing task difficulty as predicted by Fitts' Law. A main effect revealed Group 1 participants performed less accurately than Group 3 participants. Positive correlations were predominantly found between self-report measures and motor performance for Group 2 and Group 3. CONCLUSION: Imaging, and self-reported measures alone did not predict function, however, Fitts' task performance accuracy effectively differentiated groups.

Schistosomal myeloradiculopathy - A case report

Abstract The most common neurological impairments related to schistosomiasis involve the lower portions of the medulla and the cauda equina. A 22-year-old woman, with no history, signs, or symptoms of hepatointestinal schistosomiasis, presented with lumbar pain associated with acute paresthesia and paresis of the right lower limb. Spinal schistosomiasis was suspected based on the disease progression and radiological findings, and the diagnosis was confirmed after cerebrospinal fluid analysis. The authors emphasize this pathology as important as a differential diagnosis in similar clinical scenarios, especially in endemic areas, because both early diagnosis and treatment are essential to avoid permanent sequelae.

MATERIAL AND METHODS: In total, 165 rheumatologists answered an anonymous survey (sent via the internet) concerning the two exams, with respect to the following characteristics: reliability, diagnostic accuracy, the importance and necessity of these tests for diagnostic RESULTS: The study revealed that most of the rheumatologists recognised that these exams are operator-dependent, that clinicians do not rely entirely on the results, that these exams are not mandatory for the diagnoses listed, and that professionals who perform these exams should be better trained to provide reliable results. CONCLUSIONS: The Brazilian rheumatologists believe the following: the results of these exams should be interpreted with caution and are not definitive for diagnosis; musculoskeletal US and EMG should be performed by trained professionals; and there must be better preparation of the professionals who perform these exams.

Acute meningoencephalomyelitis due to varicella-zoster virus in an AIDS patient: report of a case and review of the literature / Meningoencefalomielite aguda pelo vírus varicela-zoster em um paciente com AIDS: relato de um caso e revisão da literatura

Varicella-zoster virus (VZV) meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR) technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.

A meningoencefalomielite pelo vírus varicela-zoster (VVZ) é uma complicação neurológica rara mas grave da reativação do VVZ em pacientes imunocomprometidos. Nós relatamos o caso de um indivíduo infectado por HIV que desenvolveu uma meningoencefalomielite aguda e grave acompanhada por uma erupção cutânea por causa do VVZ. A presença do DNA do VVZ no líquor foi confirmada pela técnica de reação em cadeia da polimerase (PCR). O paciente iniciou uma terapia intravenosa com aciclovir com uma leve recuperação das manifestações neurológicas. O vírus varicela-zoster deve ser incluído como uma causa de meningoencefalomielite nos pacientes com AIDS. O diagnóstico precoce seguido por terapia específica pode modificar o curso rápido e fulminante deste tipo de pacientes.

Bloqueo radicular lumbar selectivo guiado por TAC Alternativa para diagnòstico y tratamiento de radiculopatìas originadas por hernias discales y/o artrosis facetarias / Selective lumbar radicular lock replacement for CT-guided diagnosis and treatment of radiculopathy caused by herniated discs and / or facet arthrosis

El presente estudio muestra experiencia en la realización de bloqueos facetarios periarticulares y radiculares lumbares guiados Por Toomografía Axial Computada (TAC), en pacientes con dolor lumbar, o lumbociático provocado por estenosis foraminales de diversas causas, especialmente las secundarias a hernias discales foraminales sin manifestaciones de déficit motor y artrosis facetarias, en estos casos, la causa del dolor se supone se debe ala isquemia que afecta directamente las raíces nerviosas y produce sìntomas. Se realizó la evaluaciòn de 55 pacientes a los que se les efectuó este procedimiento entre los años 2007-2010 con diagnóstico de radiculopatía lumbar provocados por estenosis foraminales secundarias a hernias discales foraminales sin manifestaciones de deficít motor y artrosis facetarias y que no mejorarón con tratamiento médico - kinésico en 4 a 6 semana. 40 Hombres y 15 mujeres con edades entre 35 y 84 años. se realizaron 45 bloqueos de raíces nerviosas, a 10 pacientes se le realizó en dos espacios simultáneo en forma homolateral, y 10 facetarios periarticulares, 8 en forma bilateral. el 90% de los pacientes y refirió mejoría inmediata después del procedimiento, con resultados variables a largo plazo. la duración de la mejoría del dolor fue variable y osciló en un rango de 15 días hasta en forma permanente en el 80% de los casos. Los procedimientos en su mayoría se realizaron con internación de 24 horas. No se presentaron complicaciones técnicas ni posteriores a la inyección. En nuestra experiencia los mejores resultados se encuentran en el dolor radicular con el diagnóstico de hernia discal foraminal. Se concluye con los bloqueos facetarios y radiculares constituyen un método diagnóstico y terapéutico que puede realizarse con mucha precisión y seguridad utilizando la ayuda de imágenes diagnósticas, especialmente la TAC siendo útiles para la localización del origen del dolor y para decidir un eventual tratamiento definitivo...

SUMMARY: The following study shows our experience doing TAC-guided lumbar facet periarticular and radicular blockades in patients with lumbar or lumbociatic pain caused by foraminal stenosis due to different causes, specially those secondary to foraminal disc herniantions without motor impairment and facetary arthrosis (in these cases, the cause of the pain is supposed to be due to ischemia affecting the nerve roots which causes the symptoms). We evaluated patients to whom the procedure was performed between 2007 and 2010, with diagnosis of lumbar radiculopathy caused by foraminal stenosis secondary to foraminal disc herniations without evidence of motor impairment and facetary arthrosis, whichdidn' t improve with kinesic medical treatment in 4 to 6 weeks. 55 patients were incluided, 40 men and 15 women, between 35 and 84 years. 45 nerve root blockades, in 10 patients it was done homolaterally in two space simultaneously, and 10 periarticular facetary blockades were performed, 8 bilateral, 90% of the patients refered immediate improvement of the symptoms after the procedure, with variable long-term results. The duration of the pain relief was variable and ranged from 15 days to permanent in 80% of the cases. In most of the cases the procedure was done with 24-hour hospital stay. There were no complications, neither technical nor following the injections. In our experience the best results are achieved in the treatment of radicular pain with the diagnosis of foraminal disc herniation. In conclusion, facetary and radicular blockades represent highly precise and safe, both therapeutic and diagnostic methods, that could be used with the aid of diagnostic images, specially TAC, to localize the origin of the pain as well as to decide an eventual definitive treatment.

Eletroneuromiografia na avaliação das radiculopatias cervicais e lombossacrais / Electromyography in the evaluation of cervical and lumbosacral radiculopathy

A eletroneuromiografia (ENMG) é empregada como método de diagnóstico complementar no diagnóstico de radiculopatia desde 1950, contribuindo com importantes informações para o esclarecimento diagnóstico, planejamento do tratamento e acompanhamento evolutivo dos pacientes. A presente revisão baseada em evidências buscou referências com ênfase na indicação, sensibilidade, especificidade, reprodutibilidade e limitações do uso desse exame na avaliação das radiculopatias cervicais e lombossacrais. As referências apontam a ENMG como um exame bastante útil tanto na triagem quanto no diagnóstico diferencial na suspeita de radiculopatia cervical ou lombossacra, bem como na avaliação do grau e extensão da lesão, quando respeitadas as limitações da técnica.

Electromyography (EMG) has been employed as a complementary method in the diagnosis of radiculopathy since 1950, contributing important information for diagnostic clarification, treatment planning and patient follow-up. This evidence based review sought references with emphasis on the recommendation, sensibility, specificity, reproducibility and limitations of the use of this test in the evaluation of cervical and lumbosacral radiculopathy. The references point to EMG as being an extremely useful test both in the screening and in the differential diagnosis in the suspicion of cervical or lumbosacral radiculopathy, as well as in the evaluation of the degree and extent of the injury, when the limitations of the technique are considered.
