Risk factors for preoperative neurological impairment in patients with spinal meningioma: A retrospective multicenter study.

BACKGROUND: Patients with spinal meningioma may present preoperatively with paralysis and sensory deficits. However, there is a paucity of detailed evaluations and a lack of consensus regarding imaging findings that are predictive of neurological symptoms in patients with spinal meningioma. METHODS: Herein, a total of 55 patients who underwent surgical resection of spinal meningiomas in eight hospitals between 2011 and 2021 were enrolled. Patient characteristics, degree of muscle weakness, sensory disturbances, and the presence of bowel/bladder dysfunction (BBD) before surgical treatment were evaluated using medical records. Patients with American Spinal Injury Impairment Scale grades A-C and the presence of BBD were classified into the paralysis (+) group. Patients with sensory disturbances were assigned to the sensory disturbance (+) group. Based on magnetic resonance (MR) and computed tomography images, the tumor location was classified according to the spinal level and its attachment to the dura mater. To evaluate tumor size, the tumor occupation ratio (OR) was calculated using the area and distance measurement method in horizontal MR images, and the maximum length and area of the tumor in the sagittal plane were measured. RESULTS: Of all patients, 85 % were women. The mean age of patients at surgery was 69.7 years. Twenty-eight (51 %) and 41 (75 %) patients were classified into the paralysis (+) and sensory disturbance (+) groups, respectively. The average tumor length and area in the sagittal plane were 19.6 mm and 203 mm2, respectively; OR-area and diameters were 70.3 % and 72.3 %, respectively. In univariate analyses, tumor length and area in the sagittal plane were significant risk factors for paralysis. OR-diameter, symptom duration, and a low MIB-1 index correlated with sensory disturbances. Multivariate logistic regression analysis demonstrated that the area and length of the tumor in the sagittal plane were significantly correlated with paralysis, whereas the OR-diameter and symptom duration significantly correlated with sensory disturbances. The cut-off values for the area and length of the tumor in the sagittal plane to predict paralysis were 243 mm2 and 20.1 mm, respectively. CONCLUSIONS: Preoperative paralysis in patients with spinal meningiomas was significantly associated with sagittal tumor size than with high tumor occupancy in the horizontal plane. Sensory disturbances were associated with high occupancy in the horizontal plane. Patients with spinal meningiomas > 20 mm in length or 243 mm2 in area in the sagittal plane are at risk of developing paralysis and could be considered for surgery even in the absence of paralysis.

[Emergency management of a young patient with ponytail syndrome]. / Prise en charge en urgence d'un patient jeune victime du syndrome de la queue-de-cheval.

A 31-year-old man was brought to the emergency department because, for the past two days, he had been experiencing paresthesia-like sensory disturbances in his lower limbs, with dorsal pain that was not relieved by analgesics, as well as the appearance of sphincter disturbances and increasing difficulty in mobilization due to balance disturbances and pain. Presentation of this clinical case.

The superficial branch of the radial nerve and sensory disturbance in the radial forearm flap donor-site.

Introduction: Sensory disturbance due to injury of the superficial branch of the radial nerve (SBRN) is a donor-site morbidity of the radial forearm (RF) flap. The relationship between the SBRN preservation method and the post-operative sensation at the flap donor-site was retrospectively investigated. Methods: We included 39 patients who underwent head and neck reconstruction with a free RF flap at Hyogo Cancer Center between April 2014 and March 2018. The patients were classified into the following three groups according to the SBRN preservation method: group 1, zero preservation, excision of the entire SBRN; group 2, main trunk preservation, excision of all branches except the main trunk of the SBRN; and group 3, complete preservation, preservation of the entire SBRN. Objective sensations and subjective symptoms at the flap donor-site were analyzed. Results: The mean objective sensory scores were 3.18, 2.97, and 1.78 in groups 1, 2, and 3, respectively. Differences between groups 1 and 3 and between groups 2 and 3 were significant (p = 0.0035 and p = 0.037, respectively). The mean subjective symptom scores were 2.40, 1.33, and 1.40 in groups 1, 2, and 3, respectively. Differences between groups 1 and 2, and between groups 1 and 3 were significant (p = 0.032 and p = 0.019, respectively). Conclusions: Zero preservation method had a higher risk of subjective symptoms and objective hypoesthesia development at the flap donor-site than the complete preservation method. Despite inevitable objective hypoesthesia, the main trunk preservation prevented the development of subjective symptoms. Complete preservation is optimal for RF flap harvest; however, in case of perforator crossing, main trunk preservation is another option.

Cervical cord compression with lower limb sensory disturbance: three case reports and a literature review.

Lower limb sensory disturbance can be a false localizing sign of cervical spondylotic myelopathy. It may lead to delayed or missed diagnosis, resulting in an inappropriate management plan, especially in the presence of concurrent lumbar lesions. Three Asian patients with lower limb sensory disturbance were ineffectively treated in the lumbar region. Magnetic resonance imaging showed cervical disc herniation and cervical spinal cord compression. The patients underwent anterior cervical discectomy and interbody fusion using a stand-alone cervical interbody fusion cage. Postoperative imaging showed that the spinal cord compression was relieved. On the first postoperative day, the lower limb sensory disturbance was also relieved. The patients showed good recovery at the 3-month postoperative follow-up. These three cases of cervical cord compression with lower limb sensory disturbance were easily misdiagnosed as lumbar spondylosis. Anterior cervical discectomy and fusion had a good therapeutic effect. Therefore, the presence of lower limb sensory disturbance in a non-radicular classic pattern should always raise suspicion of a possible cord compression at a higher level.

N-of-1 Trial of Electrical Sensory Stimulation Therapy on the Tibial Innervated Area during Gait in a Case of Post-stroke Sensory Disturbance.

Background: Transcutaneous electrical sensory nerve stimulation (TESS) is used to enhance the recovery of sensorimotor function in post-stroke hemiparesis. However, TESS efficacy for post-stroke gait disturbance remains unknown. We hypothesized that TESS on the area innervated by the tibial nerve, targeting the superficial plantar sensation, combined with gait training would improve gait function in patients with gait disturbance caused by severe superficial sensory disturbance after stroke. Case: A 42-year-old man was referred to the convalescent rehabilitation hospital 4 months after a left pontine hemorrhage. He showed severe superficial sensory disturbance without motor paresis in the right lower leg and planta pedis. Gait training with TESS on the tibial nerve innervated area was performed, targeting plantar sensation according to an N-of-1 study design of a single-case ABCAB that included two 10-min sessions of gait training without TESS (phase A), two gait training sessions with TESS targeting the right plantar sensation (phase B), and one session with TESS targeting the upper leg sensation as control (phase C). The patient showed increased gait distance and stride length, improved superficial sensation on the right planta pedis, and improved balance after phase B, but not after phases A and C. Discussion: Gait training with TESS on the tibial nerve innervated area improved gait ability, superficial plantar sensation on the targeted side, and balance function in a post-stroke patient with sensory disturbance. Gait training with TESS may be effective for gait dysfunction caused by sensory disturbance in patients with central nervous system disorders.

Bone remodelling after minimally invasive surgical management of a recurrent florid cemento-osseous dysplasia in a Caucasian woman - 18 years follow-up of a unique case - A case report.

INTRODUCTION AND IMPORTANCE: Florid cemento-osseous dysplasia (FCOD) is a multifocal fibro-osseous tumour originating from the periodontal ligament that presents as being rare, benign and slow-growing. The lesion is characterised by the replacement of regular bone-structure with fibrous tissue and dysplastic bone. Depending on localisation, the initial characteristics of FCOD resemble those of periapical lesions of inflammatory origin. CASE PRESENTATION: We report on the current findings relating to the case of a 39-year-old Caucasian woman, who initially had persistent paresthesia of the right alveolaris inferior nerve (NAI) for longer than 2 weeks. The orthopantomogram showed multiple bilateral periapical radiolucency and a biopsy was indicated to rule out malignancy. Four years later, the radiolucency occurred once again in region 37, suggesting a recurrence of the lesion. Therefore, another minimally invasive surgery had to be performed, which revealed a bone cavity. Two years later, the bone of the affected region almost completely regenerated. CLINICAL DISCUSSION: We were aware that an invasive treatment could lead to infection of the hypovascular lesion. Because of the paresthesia, a biopsy was essential. Unexpectedly, the second minimally invasive surgical treatment was a significant success, as the bone lesion regenerated almost completely. CONCLUSION: The follow-up of this case was documented over more than 18 years. To date, this is the longest documented case of a FCOD. Minimally invasive surgical treatment of such lesions may lead to better bone regeneration and even a better quality of life for the patient.

Nocturnal Leg Cramps and Lumbar Spinal Stenosis: A Cross-Sectional Study in the Community.

Purpose: Nocturnal leg cramps are considered to be a symptom of lumbar spinal stenosis (LSS). However, the relationship between LSS and nocturnal leg cramps in the general population remains unclear. The purpose of this study was to investigate the prevalence and characteristics of nocturnal leg cramps in LSS in the community. Patients and Methods: 328 voluntary participants were enrolled in this study. The presence of LSS was assessed by a validated and self-administered diagnostic support tool. The presence of nocturnal leg cramps and neurological findings were evaluated by one experienced spine surgeon. To investigate the relationship between leg cramps and anatomical factors, the participants underwent an MRI scan, and the dural sac cross-sectional area (DCSA) at each lumbar intervertebral disc level was measured. Results: A total of 214 participants (65.2%) had nocturnal leg cramps, and 94 of 328 participants (28.7%) showed typical LSS symptoms. In the typical LSS symptom group, 31 participants (33.0%) had nocturnal leg cramps. In the atypical LSS symptom group, 83 participants (35.5%) had nocturnal leg cramps. There was no statistically significant difference in the prevalence of nocturnal leg cramps between the two groups. The narrowest DCSA (<25 mm2 and 25-49.4mm2) was statistically related to the presence of nocturnal leg cramp. Statistically significant differences in sensory disturbance and motor weakness were not observed between the subjects with and those without nocturnal leg cramps. Moreover, impaired PTR was statistically related to the presence of nocturnal leg cramp. Conclusion: The prevalence of nocturnal leg cramps did not differ with or without typical LSS symptoms in the community. The degree of dural tube compression that is determined by DCSA had a direct effect on the presence of nocturnal leg cramps. Neurological impairment, such as PTR abnormalities, was associated with the presence of nocturnal leg cramps.

Trigeminal neuralgia and other cranial pain syndromes.

Spontaneous Trigeminal Neuralgia is a painful condition of the face which may require interventional treatment if medicines fail to control the pain. These include microvascular decompression (MVD) and GKNS. The former is moderately more effective but GKNS has become accepted both as an alternative to MVD or as an adjunct. Like all treatments of the condition, it is successful in a majority of patients but by no means all. Repeat treatments are possible. When Trigeminal Neuralgia is secondary to other conditions the response to GKNS is different. With AVMs, Dural Arteriovenous Fistulae and Epidermoids, the dose to treat the visible lesion usually cures the neuralgia. With meningiomas it is necessary to treat the neuralgia as a separate entity with a neuralgia dose focused on the nerve. GKNS does not improve the rare neuralgia associated with Vestibular Schwannomas. It works with Multiple Sclerosis but not as well as with the spontaneous illness. There is some evidence that GKNS can be useful with the rare Glossopharyngeal and Sphenopalatine Neuralgias.

Neuropsychological and neurophysiological features of WAGR syndrome: Detailed comprehensive evaluation of a patient with severe intellectual disability and autism spectrum disorder.

BACKGROUND: Wilms' tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome is a contiguous gene deletion syndrome caused by a de novo deletion including the 11p13 region. Although autism spectrum disorder (ASD) is frequently observed in patients with WAGR syndrome, few reports have comprehensively described its characteristics. We herein present the detailed neuropsychological and neurophysiological findings of a patient with WAGR syndrome complicated with severe psychomotor developmental delay and ASD. CASE PRESENTATION: The patient is presently a 6-year-old boy. Microarray analysis revealed a 7.1 Mb loss at 11p14.3-p13 and a 9.3 Mb loss at 11p13-p12, which encompassed the PAX6, WT1, and PRRG4 genes. His behavioral features were characteristic even among the ASD population: severe hypoesthesia to touch, pain, and temperature in addition to remarkable sensory seeking posing a high risk of serious accident. Sensory Profile analysis objectively identified a strong preference for sensory stimulation. Furthermore, his somatosensory evoked potential (SSEP) showed a mild delay in central conduction time, suggesting partial brain stem dysfunction-induced hypoalgesia. DISCUSSION: This first attempt to characterize sensory dysfunction using Sensory Profile and SSEP in WAGR syndrome may contribute to understanding its neuropsychological features and improve the quality of rehabilitation and socioeducational support in affected children.

Lateral Medullary Infarction with Contralateral Segmental Dysesthesia and Ipsilateral Headache: A Case Report.

INTRODUCTION: The medulla oblongata is the lowest segment of the brain stem, located adjacent to the spinal cord, with a complex anatomical structure. Thus, a small injury to the medulla oblongata can show complex clinical manifestations. CASE PRESENTATION: A patient experienced dysesthesia, which manifested as numbness in her right lower limb and decreased temperature sense, and dizziness 20 days before admission. The numbness worsened 1 week before admission, reaching the right Thoracic (T) 12 dermatomes. Her thermoception below the T12 dermatomes decreased, and the degree of dizziness increased, accompanied by nausea and vomiting. Magnetic Resonance Imaging (MRI) of the neck, chest, and abdomen performed at a local hospital showed no abnormalities. MRI of the brain was performed after admission. One week after admission, she experienced a severe headache in the upper left periorbital area. The numbness extended to T4, and thermoception decreased below T4. DIAGNOSIS: Lateral medullary infarction. INTERVENTIONS: Anti-platelet aggregation and mitochondrial nutritional therapies were performed along with treatments for improving circulation and establishing collateral circulation. OUTCOMES: The intensity of limb numbness decreased, and the symptoms of headache and dizziness resolved. CONCLUSION: Lesions leading to segmental sensory disorders can occur in the medulla oblongata. Ipsilateral headaches with contralateral segmental paresthesia can be a specific sign of lateral medullary infarction.

Pain, numbness, or both? Distinguishing the longitudinal course and predictors of positive, painful neuropathic features vs numbness after breast cancer surgery.

INTRODUCTION: Both positive (burning, stabbing, and allodynia) and negative (numbness) neuropathic symptoms may arise after surgery but likely contribute differently to patients' postoperative pain experience. Numbness has been identified as divergent from positive neuropathic symptoms and therefore excluded from some neuropathic assessment tools (Neuropathic Pain Scale for PostSurgical patients [NeuPPS]). OBJECTIVES: In this prospective longitudinal study of patients undergoing breast surgery, we aimed to delineate the time course of numbness and its coincidence with NeuPPS and to contrast the association of surgical, psychosocial, and psychophysical predictors with the development of negative vs positive neuropathic symptoms. METHODS: Patients reported surgical area sensory disturbances at 2 weeks and 3, 6, and 12 months postoperatively. Association of baseline demographic, surgical, psychosocial, and psychophysical factors with NeuPPS and numbness across time was investigated using generalized estimating equation linear and logistic regression. RESULTS: Numbness was consistently reported by 65% of patients; positive neuropathic symptoms were less common, often decreasing over time. Neuropathic Pain scale for PostSurgical patients and numbness co-occurred in half of patients and were both associated with greater clinical pain severity and impact, younger age, axillary surgery, and psychosocial factors. More extensive surgery and chemotherapy were only associated with numbness. Conversely, other chronic pain, lower physical activity, perioperative opioid use, negative affect, and lower baseline pressure pain threshold and tolerance were only associated with NeuPPS. Patients reporting numbness alone did not endorse substantial clinical pain. CONCLUSIONS: Differentiation of predictors, prevalence, and time course of numbness vs NeuPPS in breast surgical patients revealed important distinctions, suggesting that their independent assessment is worthwhile in future studies of postsurgical pain.

Detailed Analysis of Neurological Symptoms and Sensory Disturbances Due to Chronic Arsenic Exposure in Toroku, Japan.

As a result of population growth and the development of tube wells, humans' exposure to arsenic has increased over the past few decades. The natural course of organ damage secondary to arsenic exposure is not yet well understood. In Toroku, Japan, an arsenic mine was intermittently operated from 1920 to 1962, and residents were exposed to high concentrations of arsenic. In this paper, we analyzed 190 consecutive residents for whom detailed records of neurological symptoms and findings were obtained from 1974 to 2005. All participants were interviewed regarding the presence of general, skin, hearing, respiratory, and neurological symptoms. Neurological symptoms were classified into extremity numbness or pain, constipation, dyshidrosis, sensory loss, and muscle atrophy. Superficial and vibratory sensation was also evaluated. More than 80% of participants experienced extremity numbness, and numbness was the most common neurological symptom. Numbness was associated with superficial sensory disturbance, and was correlated with the subsequent development of other neurological symptoms, including autonomic and motor symptoms. No previous studies have investigated the natural course of chronic arsenic intoxication; thus, these data serve as a guide for detecting early symptoms due to arsenic exposure.

Low Risk of Persistent Pain, Sensory Disturbances, and Complications Following Mastectomy After Gender-Affirming Surgery.

Purpose: In recent years, there has been a significant increase in referrals for gender-affirming surgery to departments of plastic surgery in Denmark. There is currently no literature on postsurgical pain in trans men after mastectomy. We aimed at investigating the prevalence and severity of postsurgical persistent pain, sensory disturbances, and complications in trans men after mastectomy. Methods: The 90 trans men who underwent bilateral mastectomy between September 1, 2013 and August 31, 2018 were included. Patients' files were evaluated for complications, and 84 (response rate 93.3%) patients answered a questionnaire (validated for women undergoing oncologic mastectomy) regarding persistent pain and sensory disturbances. Results: Twenty-three patients (27.4%) reported either unilateral or bilateral persistent pain after mastectomy. Of these, 14 (60.9%) patients categorized the pain as mild. However, 77 (95.2%) of the patients did not use analgesics and nonopioid pain medication was sufficient for the remainder. Sensory disturbances were found in 44 (47.5%) of the patients, and 4 (4.8%) patients reported clear signs of neuropathic pain. Seven (7.8%) patients developed hematomas, and areola necrosis was seen in four (4.4%) patients. Due to infection, seven (7.8%) patients received antibiotics. Conclusion: Mastectomy as a part of gender-affirming surgery is a safe procedure with a few, nonsevere, complications. Although a quarter of the patients experienced persistent pain, the majority of that pain is mild, intermittent and can be treated with nonopioid pain medication.

Factors Associated with Medical Device Related Pressure Ulcer Caused by Ankle Foot Orthosis / The Japanese Journal of Rehabilitation Medicine

Purpose：We investigated the factors associated with medical device-related pressure ulcer (MDRPU) due to lower extremity orthosis in patients undergoing convalescent rehabilitation for stroke.Methods：This retrospective study included patients with stroke who wore ankle foot orthosis in the convalescent rehabilitation ward. We measured the following items at admission：Brunnstrom recovery stage, presence of sensory disturbance, exhibition of unilateral spatial neglect, functional independence measures at admission and discharge, and presence of MDRPU. In the statistical analysis, logistic regression analysis was performed to identify the significant factors associated with MDRPU.Results：Ninety-five participants were enrolled in this study (mean age：54.9 ± 11.6 years, Male：78.9%). In logistic regression analysis, Age (odds ratio＝1.05, 95% confidence interval＝1.01-1.10, p＜0.05) and the presence of sensory disturbance (odds ratio＝5.17, 95% confidence interval＝1.39-19.28, p＜0.05) at admission was extracted as the cause of MDRPU.Conclusion：Sensory disturbance at admission is associated with MDRPU in patients undergoing convalescent rehabilitation for stroke who wear ankle foot orthosis.

New Method for the Quantitative Assessment of Sensory Disturbances in Cervical Myelopathy: Application for Neurological Level Diagnosis.

INTRODUCTION: Cervical myelopathy frequently manifests as sensory disturbances, including numbness, and their distribution pattern aids in neurological level diagnosis. However, the objective assessment of sensory disturbances is challenging. In this study, we attempted to quantitatively evaluate sensory symptoms in patients with cervical myelopathy according to lesion level using PainVisionⓇ. METHODS: Dermal sensations were evaluated in patients (n = 158) and healthy volunteers (n = 100) using PainVisionⓇ PS-2100, which measured the current perception threshold (CPT). The results were analyzed for their correlation with magnetic resonance imaging (MRI) data, visual analog scale (VAS) scores, and patient functional status assessed by the Japanese Orthopaedic Association (JOA) and JOA Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) scores. RESULTS: Forearm and palm CPT values were significantly higher in patients with cervical myelopathy (both sites, P < 0.001) and were negatively correlated with the JOA score (forearm, r = -0.33; palm, r = -0.35; P < 0.001) and the JOACMEQ scores for upper extremity function (forearm, r = -0.37; palm, r = -0.39; P < 0.001), lower extremity function (forearm, r = -0.39; palm, r = -0.40; P < 0.001), and quality of life (forearm r = -0.27, P = 0.0025); however, no correlation was observed with the VAS score. Stratification of patients according to their lesion levels determined by MRI revealed that the C3/C4 subgroup had significantly higher forearm CPT values than the C4/C5 (P = 0.024) and C5/C6 (P = 0.0013) subgroups and higher palm CPT values than the C5/C6 subgroup (P = 0.009). CONCLUSIONS: Quantitative measurements of sensory disturbances using the PainVisionⓇ device correspond to the degree of patient functional disability and the lesion level. This indicates that both the distribution and intensity of sensory abnormalities are important for neurological level diagnosis in patients with cervical myelopathy.

Strategy for the treatment of lateral epicondylitis of the elbow using denervation surgery.

BACKGROUND: A number of treatments for lateral epicondylitis of the elbow have been described. We have developed a strategy for the treatment of this condition. METHODS: We diagnosed lateral epicondylitis of the elbow in 86 patients. Conservative treatment resulted in resolution in 71 patients. Surgery was required in the remaining 15 patients. If the posterior branch of the posterior cutaneous nerve of the forearm showed a positive response to local anesthesia (block test), we performed denervation surgery on the posterior branch of the posterior cutaneous nerve of the forearm. Patients were asked to rate the degree of pain and sensory disturbance using a visual analog scale; the 11-item version of the Disabilities of the Arm, Shoulder and Hand measure; and the Patient-Rated Elbow Evaluation. RESULTS: A positive response to the block test was seen in 10 elbows (67%). After denervation surgery, pain relief was seen in 9 of 10 elbows (90%). The mean follow-up period was 30.4 months. At final follow-up, the average scores on the visual analog scale, 11-item version of the Disabilities of the Arm, Shoulder and Hand, and Patient-Rated Elbow Evaluation were 4.3 mm, 10.45 points, and 5.9 points, respectively. In the early period after denervation surgery, sensory disturbance was observed in 9 cases (90%). CONCLUSION: Our strategy of denervation surgery for lateral epicondylitis of the elbow was effective for pain relief among patients showing a positive response to the block test.

An atypical pontine infarction presenting with segmental sensory disturbance and uncrossed sensory symptomatology: case report.

We reported a patient who presented with analgesia and thermanaesthesia from the face to T4 dermatome on the contralateral side to the lesion due to infarction of the dorsal tegmentum of the caudal pons, which was inconsistent with classical dorsolateral pontine infarction. We speculated that the lesion affected the trigeminothalamic tract deriving from the second-order neurons on the contralateral side and partial lateral spinothalamic tracts carrying pain and temperature sensation above T4 dermatome, while the spinal trigeminal tract and its nucleus on the ipsilateral side and other parts of lateral spinothalamic tracts were spared. This case showed the atypical presentations of dorsolateral pontine infarction and may provide clinicians with new diagnostic ideas.
