Effect of Neural Tissue Mobilization on Sensory-Motor Impairments in Breast Cancer Survivors with Lymphedema: An Experimental Study.

BACKGROUND: Breast surgery, Axillary Lymph Node Dissection (ALND), radiation and chemotherapy may develop several complications such as axillary web syndrome, frozen shoulder, numbness, shoulder pain and range of motion restriction, lymphostasis, and lymphedema. Up to 77% report sensory disturbance in the breast or arm after breast surgery. These short- and long-term consequences have dramatic impact on physical function and quality of life in this population. AIMS: The aim of the study was to determine the effect of neural tissue mobilization on sensory-motor impairments in breast cancer survivors with lymphedema. SUBJECTS AND METHODS: This study was carried out by analyzing total 100 breast cancer survivor women, with lymphedema aged between 30-65 years of age who had undergone breast surgery mostly lumpectomy along with chemotherapy or radiation therapy. Participants were divided into two groups by random allocation. One group underwent neurodynamic mobilization and the other group conventional physiotherapy.The treatment protocol was given for 6 weeks. Parameters such ROM, pain, lymphedema and sensory-motor impairments were assessed at the baseline before the treatment and 6 weeks after the treatment. RESULT: The result from this study shows that there is significant improvement (p<0.0001, t-value 4.69) in mTNS of patients undergoing neural tissue mobilization,whereas there was no significant improvement (p=0.05, t-value 1.951) seen in patients undergoing conventional physiotherapy. CONCLUSION: This study concludes that effect of neural tissue mobilization has significant impact on sensory motor impairments as compared to conventional treatment protocol in breast cancer survivors with lymphedema.Pain and ROM showed similar difference with both the treatment protocols. It was also observed that patients with mild and moderate lymphedema showed significant improvement as compared to patients with severe lymphedema.

Subjective experience, cognitive functioning and trauma level of patients undergoing awake craniotomy due to brain tumor - Preliminary study.

BACKUP AND OBJECTIVE: Awake craniotomy (AC) for brain tumors, when the patient is conscious during the operation, allows to reduce the risk of motor disability and aphasia, however, it may be a source of extreme stress. The aim of our study was to examine the patients' subjective experience of the surgery including the level of psychological trauma and cognitive functioning. METHOD: Eighteen patients operated due to brain tumor were enrolled in this study. The Essener Trauma-Inventory Questionnaire and the Addenbrooke's Cognitive Examination (ACE III) were administrated. The patients' experience with awake craniotomy was evaluated with a qualitative descriptive survey. RESULTS: All patients remembered the intraoperative neuropsychological examination and several sensations like: drilling, cold, head clamp fixation or having eyes covered. In most of the patients the postoperative psychological trauma experience did not reach the clinical level. The ACE III postoperative scores revealed partial cognitive deficits with the lowest scores in memory and word fluency domains. Slight amnestic aphasia was observed postoperatively only in two patients. CONCLUSIONS: Awake craniotomy for resection of brain tumors is well-tolerated by patients and does not cause significant psychological trauma. Nonetheless, anxiety about the procedure warrants further study and individualized neuropsychological care is needed for the emotional preparation of the patient.

Epilepsy surgery reduced seizure frequency for patients with severe motor and intellectual disorders.

INTRODUCTION: Little is known about epilepsy surgery for patients with severe motor and intellectual disorders (SMIDs). We hypothesized that epilepsy surgery could reduce epileptic seizure frequency in these patients. The purpose of this study was to compare pre- and postoperative seizure frequency in patients with SMIDs. METHODS: A total of 288 surgeries were performed for pediatric patients, including those with SMIDs, from 2009 to 2018. Inclusion criteria were as follows: Oshima classification 1 (intelligence quotient <20 and bedridden), ≥2 years old, proven ictal events evaluated by long-term video electroencephalography, and ≥1-year follow-up. Seizure frequency and the number of antiseizure medications (ASMs) were compared between pre- and postepilepsy surgery. Patients' respiratory and feeding conditions were also examined to determine comorbidities. RESULTS: Nineteen patients (5 girls, 14 boys; age: 2 to 12 years) fulfilled the inclusion criteria. One patient underwent focus resection, 2 patients underwent total corpus callosotomy, and 16 patients underwent vagus nerve stimulation therapies. Of 19 patients, 16 (84.2%) had daily seizures, and 3 (15.8%) had weekly seizures before surgery. Epilepsy surgery significantly reduced seizure frequency (p = 0.029). Five patients (26.3%) had status epilepticus (SE) before surgery, which disappeared in all but one after surgery (p = 0.046). The number of ASMs did not change between before and after surgery (p = 0.728). CONCLUSION: Epilepsy surgery reduced the frequency of epileptic seizures and improved SE even among patients with compromised respiratory function and compromised food intake.

Efficacy of per-oral endoscopic myotomy for the treatment of non-achalasia esophageal motor disorders.

INTRODUCTION: Per-oral endoscopic myotomy (POEM) is effective in achalasia. The objective of this study was to evaluate the short-term clinical efficacy of POEM in non-achalasia esophageal motility disorders (NAEMD). PATIENTS AND METHODS: Patients with NAEMD diagnosed by high-resolution manometry were included in a retrospective multicentric study. For each individual case, two controls paired on gender and age were matched: one with type I/II achalasia and one with type III achalasia. The clinical response, defined by an Eckardt score ≤ 3, was assessed at 3 and 6 months. RESULTS: Ninety patients (mean age 66 years, 57 men) were included, 30 patients with NAEMD (13 jackhammer esophagus, 6 spastic esophageal disorders, 4 nutcracker esophagus, and 7 esophagogastric junction obstruction), 30 patients with type I-II achalasia, and 30 patients with type III achalasia. The 3-month response rates were 80% (24/30), 90% (27/30), and 100% (30/30) in NAEMD, type I-II achalasia and type III achalasia, respectively (p < 0.01). Eckardt scores improved from preoperative baseline in all groups (median scores 2.0 after POEM vs. 6.5 before POEM, 1.3 vs. 7.2, and 0.5 vs. 6.1 in NAEMD, type I//I and Type III, respectively). No predictive factor of response was identified. In NAEMD patients, there was a significant improvement of dysphagia, regurgitation, and chest pain scores. The 6-month response rates were 63.2% (12/19), 95.5% (21/22), and 87.0% (20/23) in NAEMD, type I-II achalasia and type III achalasia, respectively (p = 0.03). CONCLUSION: Although less effective than in achalasia, POEM is an effective treatment for NAEMD. Long-term follow-up data are needed to further confirm that POEM may be a valid treatment of NAEMD.

Anti-CNTN1 IgG3 induces acute conduction block and motor deficits in a passive transfer rat model.

BACKGROUND: Autoantibodies against the paranodal protein contactin-1 have recently been described in patients with severe acute-onset autoimmune neuropathies and mainly belong to the IgG4 subclass that does not activate complement. IgG3 anti-contactin-1 autoantibodies are rare, but have been detected during the acute onset of disease in some cases. There is evidence that anti-contactin-1 prevents adhesive interaction, and chronic exposure to anti-contactin-1 IgG4 leads to structural changes at the nodes accompanied by neuropathic symptoms. However, the pathomechanism of acute onset of disease and the pathogenic role of IgG3 anti-contactin-1 is largely unknown. METHODS: In the present study, we aimed to model acute autoantibody exposure by intraneural injection of IgG of patients with anti-contacin-1 autoantibodies to Lewis rats. Patient IgG obtained during acute onset of disease (IgG3 predominant) and IgG from the chronic phase of disease (IgG4 predominant) were studied in comparison. RESULTS: Conduction blocks were measured in rats injected with the "acute" IgG more often than after injection of "chronic" IgG (83.3% versus 35%) and proved to be reversible within a week after injection. Impaired nerve conduction was accompanied by motor deficits in rats after injection of the "acute" IgG but only minor structural changes of the nodes. Paranodal complement deposition was detected after injection of the "acute IgG". We did not detect any inflammatory infiltrates, arguing against an inflammatory cascade as cause of damage to the nerve. We also did not observe dispersion of paranodal proteins or sodium channels to the juxtaparanodes as seen in patients after chronic exposure to anti-contactin-1. CONCLUSIONS: Our data suggest that anti-contactin-1 IgG3 induces an acute conduction block that is most probably mediated by autoantibody binding and subsequent complement deposition and may account for acute onset of disease in these patients. This supports the notion of anti-contactin-1-associated neuropathy as a paranodopathy with the nodes of Ranvier as the site of pathogenesis.

Spontaneous regression of herniated nucleus pulposus: The clinical findings of 76 patients.

Lumbar disc hernia is common disease, affecting about 5% of the population. Many studies to date reported regression of disc herniation without surgical intervention.Medical records of the patients who applied to the spine clinic in an outpatient setting were retrospectively reviewed. Age, sex, radiological findings, neurological examinations, and medical treatments of the patients were evaluated.Male patients constituted 52.6% of the cases (n = 40) and 47.4% (n = 36) were female. The ages of the patients ranged from 25 to 82 years, with a mean of 48.5 ±â€Š12.1 years. Visual analog scale (VAS) measurements ranged from 0 to 8 and the mean was determined as 2.65 ±â€Š1.98. The VAS score of pain severity of 12 (15.78%) cases was 0, VAS score of 39 (51.31%) cases was 1 to 3, VAS score of 20 (26.31%) cases was 4 to 6, VAS score of 5 (6.57%) cases was 7 to 10. Eighteen (23.68%) of the cases underwent neuropathic pain treatment for more than 6 months. Fifteen (19.7%) patients also developed permanent motor deficits.Findings of our study show that there was no direct association between radiological improvement and clinical improvement. Indication for surgery still existed in a high number of patients, substantial of which developed permanent motor deficits. Current results suggest that we need to advise our patients in favor of early surgery as soon as indication for surgery is established upon neurological and radiological examination.

[Spinal dural arteriovenous fistulas. A series of clinical cases and an analysis of the literature data]. / Dural'nye spinal'nye arteriovenoznye fistuly. Seriia sobstvennykh klinicheskikh nabliudenii i analiz dannykh literatury.

Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular malformation of the spinal cord, causing segmental lesions of the spinal cord due to venous ischemia. Functional outcomes of treatment in SDAVF patients are favorable, but the rate of improvement varies from 25 to 100%, which complicates prediction of the treatment outcome. AIM: the study aim was to identify a relationship between fistula localization and clinical manifestations and evaluate the effect of disease duration and severity of neurological impairments on immediate and long-term treatment outcomes, based on analysis of the literature and own data. MATERIAL AND METHODS: In September 2016, we performed a PubMed search for publications using keywords 'spinal arteriovenous fistula', 'treatment', and 'outcome'. We selected publications containing information on the patient's age, fistula location, disease duration, and evaluation of symptom severity (Aminoff-Logue scale) preoperatively, postoperatively, and at least 3 months after surgery. The analysis also included data on patients operated on at the clinic. A total of 187 patients were included in the analysis. RESULTS: The fistula was most often located at the T6, T7, and T9 level, with motor disorders being more severe for fistulas located at or below the T9 vertebra. Surgical isolation of the fistula improved the functional state of patients, with patients under the age of 60 years having a better prognosis for recovery of impaired functions. Motor disorders significantly regressed in the early postoperative period in all patients, but in the long-term period, there was worsening of motor disorders in patients with a better baseline functional state.

[Surgical treatment of eloquent brain area tumors using neurophysiological mapping of the speech and motor areas and conduction tracts]. / Khirurgicheskoe lechenie opukholei funktsional'no znachimykh zon golovnogo mozga s primeneniem metoda neirofiziologicheskogo kartirovaniya rechevykh, motornykh zon i provodyashchikh putei.

AIM: To evaluate the efficacy of intraoperative neurophysiological mapping in removing eloquent brain area tumors (EBATs). MATERIAL AND METHODS: Sixty five EBAT patients underwent surgical treatment using intraoperative neurophysiological mapping at the Pirogov National Medical and Surgical Center in the period from 2014 to 2015. On primary neurological examination, 46 (71%) patients were detected with motor deficits of varying severity. Speech disorders were diagnosed in 17 (26%) patients. Sixteen patients with concomitant or isolated lesions of the speech centers underwent awake surgery using the asleep-awake-asleep protocol. Standard neurophysiological monitoring included transcranial stimulation as well as motor and, if necessary, speech mapping. The motor and speech areas were mapped with allowance for the preoperative planning data (obtained with a navigation station) synchronized with functional MRI. In this case, a broader representation of the motor and speech centers was revealed in 12 (19%) patients. During speech mapping, no speech disorders were detected in 7 patients; in 9 patients, stimulation of the cerebral cortex in the intended surgical area induced motor (3 patients), sensory (4), and amnesic (2) aphasia. In the total group, we identified 11 patients in whom the tumor was located near the internal capsule. Upon mapping of the conduction tracts in the internal capsule area, the stimulus strength during tumor resection was gradually decreased from 10 mA to 5 mA. Tumor resection was stopped when responses retained at a stimulus strength of 5 mA, which, when compared to the navigation data, corresponded to a distance of about 5 mm to the internal capsule. Completeness of tumor resection was evaluated (contrast-enhanced MRI) in all patients on the first postoperative day. RESULTS: According to the control MRI data, the tumor was resected totally in 60% of patients, subtotally in 24% of patients, and partially in 16% of patients. In the early postoperative period, the development or aggravation of a motor neurological deficit was detected in 18 patients: worsening of paresis was observed in 11 patients, and worsening of speech disorders occurred in 7 patients. After 4 months, motor and speech disorders regressed in 10 patients. Therefore, a persistent neurological deficit developed after surgery in 8 (12%) patients (motor deficit in 5 cases; speech deficit in 3 cases). CONCLUSION: Resection of eloquent brain area tumors using intraoperative neurophysiological monitoring enables complete resection of the tumor at a low risk of persistent neurological deficits, which ultimately improves the patient's life prognosis.
