    Conclusion: Motor deficits, sensory deficits, and cauda equina dysfunction were significantly improved immediately after urgent surgery. After 6 weeks, motor and sensory deficits were also significantly improved compared to the neurological status at discharge. Thus, we advocate immediate surgery of disc herniation in patients with acute onset of motor deficits, perineal numbness, or bladder or bowel dysfunction indicative of cauda equina syndrome.

    Full Text Available There has been an increase in prevalence of low severity dysfunctions such as minor neurological dysfunction and cognitive deficits which consequently lead to school and behavior problems. The study presents the outcomes of a small group of preterm children with different medical complications at birth on follow-up at toddler age. In the neonatal period and at three months corrected age the neurological examination by the Amiel-Tison neurological assessment and the assessment of general movements was done. Both measures were compared with the criterion measure Bayley Scales of Infant Development - II. Results of the preterm group were compared with results of the normative group. According to results for both methods of neurological examination, children were classified into different categories meaning optimal or different degrees of non-optimal neurological results. The results of the children from different categories of neurological functioning were compared with the criterion measure. Children from the preterm group attained lower results on the developmental test compared to normative data. Children from groups with the lowest birth weight and gestational age attained the lowest results. These findings suggest that children from less optimal or non-optimal categories according to both methods of neurological examination attained lower developmental scores. The difference between groups was higher on the mental scale than on the motor scale of the developmental test.

    Full Text Available Abstract Drowning is a major source of mortality and morbidity in children worldwide. Neurocognitive outcome of children after drowning incidents cannot be accurately predicted in the early course of treatment. Therefore, aggressive out-of-hospital and in-hospital treatment is emphasized. There are "miracle" cases after long submersion times that have been reported in the medical literature, which mostly concern small children. However, many of the survivors will remain severely neurologically compromised after remarkably shorter submersion times and will consequently be a great burden to their family and society for the rest of their lives. The duration of submersion, the need of advanced life support at the site of the accident, the duration of cardiopulmonary resuscitation, whether spontaneous breathing and circulation are present on arrival at the emergency room are important factors related to survival with mild neurological deficits or intact function in drowned children. Data on long-term outcome are scarce. The used outcome measurement methods and the duration of follow-up have not been optimal in most of the existing studies. Proper neurological and neurophysiological examinations for drowned children are superior to outcome scales based chart reviews. There is evidence that gross neurological examination at the time of discharge from the hospital in young children does not reveal all the possible sequelae related to hypoxic brain injury and thus long-term follow-up of drowned resuscitated children is strongly recommended.

    Urea cycle disorders encompass several enzyme deficiencies that can result in cerebral damage, with a wide clinical spectrum from asymptomatic to severe. The goal of this study was to correlate brain MRI abnormalities in urea cycle disorders with clinical neurological sequelae to evaluate whether MRI abnormalities can assist in guiding difficult treatment decisions. We performed a retrospective chart review of patients with urea cycle disorders and symptomatic hyperammonemia. Brain MRI images were reviewed for abnormalities that correlated with severity of clinical neurological sequelae. Our case series comprises six urea cycle disorder patients, five with ornithine transcarbamylase deficiency and one with citrullinemia type 1. The observed trend in distribution of brain MRI abnormalities as the severity of neurological sequelae increased was the peri-insular region first, extending into the frontal, parietal, temporal and, finally, the occipital lobes. There was thalamic restricted diffusion in three children with prolonged hyperammonemia. Prior to death, this site is typically reported to be spared in urea cycle disorders. The pattern and extent of brain MRI abnormalities correlate with clinical neurological outcome in our case series. This suggests that brain MRI abnormalities may assist in determining prognosis and helping clinicians with subsequent treatment decisions. (orig.)

    Full Text Available Background: Subdural hematoma (SDH is a common disease entity treated by neurosurgical intervention. Although the incidence increases in the elderly population, there is a paucity of studies examining their surgical outcomes. Objectives: To determine the neurological and functional outcomes of patients over 70 years of age undergoing surgical decompression for subdural hematoma. Materials and Methods: We retrospectively reviewed data on 45 patients above 70 years who underwent craniotomy or burr holes for acute, chronic or mixed subdural hematomas. We analyzed both neurological and functional status before and after surgery. Results: Forty-five patients 70 years of age or older were treated in our department during the study period. There was a significant improvement in the neurological status of patients from admission to follow up as assessed using the Markwalder grading scale (1.98 vs. 1.39; P =0.005, yet no improvement in functional outcome was observed as assessed by Glasgow Outcome Score. Forty-one patients were admitted from home, however only 20 patients (44% were discharged home, 16 (36% discharged to nursing home or rehab, 6 (13% to hospice and 3 (7% died in the postoperative period. Neurological function improved in patients who were older, had a worse pre-operative neurological status, were on anticoagulation and had chronic or mixed acute and chronic hematoma. However, no improvement in functional status was observed. Conclusion: Surgical management of SDH in patients over 70 years of age provides significant improvement in neurological status, but does not change functional status.

  10. Neurologic Outcomes in Very Preterm Infants Undergoing Surgery.

    LENUS (Irish Health Repository)

    2012-01-31

    OBJECTIVE: To investigate the relationship between surgery in very preterm infants and brain structure at term equivalent and 2-year neurodevelopmental outcome. STUDY DESIGN: A total of 227 infants born at <30 weeks gestation or at a birth weight of <1250 g were prospectively enrolled into a longitudinal observational cohort for magnetic resonance imaging and developmental follow-up. The infants were categorized retrospectively into either a nonsurgical group (n=178) or a surgical group (n=30). Nineteen infants were excluded because of incomplete or unsuitable data. The surgical and nonsurgical groups were compared in terms of clinical demographic data, white matter injury, and brain volume at term. Neurodevelopmental outcome was assessed at age 2 years. RESULTS: Compared with the nonsurgical group, the infants in the surgical group were smaller and more growth-restricted at birth, received more respiratory support and oxygen therapy, and had longer hospital stays. They also had smaller brain volumes, particularly smaller deep nuclear gray matter volumes. Infants who underwent bowel surgery had greater white matter injury. Mental Developmental Index scores were lower in the surgical group, whereas Psychomotor Developmental Index scores did not differ between the groups. The Mental Developmental Index difference became nonsignificant after adjustment for confounding variables. CONCLUSION: Preterm infants exposed to surgery and anesthesia had greater white matter injury and smaller total brain volumes, particularly smaller deep nuclear gray matter volumes. Surgical exposure in the preterm infant should alert the clinician to an increased risk for adverse cognitive outcome.

  11. Heat strokes: aetiopathogenesis, neurological characteristics, treatment and outcome.

    Heat stroke is a thermal insult to the cerebral thermoregulatory system controlling heat production and heat dissipation. The thermal insult may be environmental as in 'classic heat stroke' or endogenous as in 'exertional heat stroke' in joggers or runners. The insult will lead to a steady rise in body core temperature to 40 degrees C or more, exhaustion of sweating with hot dry skin and central nervous system disturbances ranging from confusion to deep coma. Multisystem insult will follow leading to a fatal outcome, if not diagnosed and treated promptly. Rapid evaporative cooling and support of vital organs are the essential factors in the management of this condition. If treated early, no sequelae results, however, pancerebellar syndrome and spastic or flaccid paraparesis have been described in a few cases. Limited sun exposure, proper use of sunscreens, adequate fluid and electrolyte replacement and acclimatization are the key factors for prevention. Despite appropriate prevention and prompt treatment, heat stroke is unlikely to be totally prevented, but the mortality has improved dramatically to less than 10%. PMID:9588849

    Full Text Available Background: Non neurological outcome postsurgical stabilization in C-spine injury has not been reported. Non neurological outcome i.e. the risk of lung infection (pneumonia, systemic inflammation response syndrome (SIRS, length of postoperative care (LOPOC which can compromise the recovery process and treatment period. This study aims to investigate non neurological outcome comparison after early surgical stabilization (ESS and delayed surgical stabilization (DSS in patients with C-spine fractures. Methods: The author retrospectively reviews 59 of 108 consecutive patients who met the inclusion criteria with C-spine fractures who underwent surgical stabilization at the Sanglah General Hospital, between 2007 and 2010. Consisting of 25 patients underwent ESS and 34 patients were treated by DSS. The last follow up period range was 3-36 months. Non neurological outcome were evaluated and compared; the risk of pneumonia, SIRS and LOPOC. Results: Significant statistically between ESS and DSS in; the risk of pneumonia (ESS: DSS= 1:9 by Chi-square-test (p=0.023; the risk of SIRS (ESS: DSS= 1:11 by Chi-square-test (p=0.008; and the LOPOC (ESS: DSS= 6.84:9.97 by independent t-test (p=0.000. Application of ESS for C-spine fractures could provide early mobilization, prompt treatment and facilitate early rehabilitation thus significantly reduces complications due to prolong immobilization and reduces LOPOC. Conclussion: It can be concluded that the ESS strategy is effective and efficient thus may propose an option of surgical timing in C-spine fractures.

    Studies about long-term outcome following abusive head trauma (AHT) are scarce. The aims of this study were to report long-term neurological, cognitive, behavioral and academic outcomes, ongoing treatments and/or rehabilitation, several years after AHT diagnosis, and factors associated with outcome. In this retrospective study, all patients admitted to a single rehabilitation unit following AHT between 1996 and 2005, with subsequent follow-up exceeding 3 years, were included. Medical files were reviewed and a medical interview was performed with parents on the phone when possible. The primary outcome measure was the Glasgow Outcome Scale (GOS). Forty-seven children (out of 66) met the inclusion criteria (mean age at injury 5.7 months; SD=3.2). After a median length of follow-up of 8 years (range 3.7-12), only seven children (15%) had "good outcome" (normal life - GOS I) and 19 children (40%) presented with severe neurological impairment (GOS III and IV). Children sustained epilepsy (38%), motor deficits (45%), visual deficit (45%), sleep disorders (17%), language abnormalities (49%), attention deficits (79%) and behavioral disorders (53%). Most children (83%) had ongoing rehabilitation. Only 30% followed a normal curriculum, whereas 30% required special education services. Children with better overall outcome (GOS I and II) had significantly higher educated mothers than those with worse outcomes (GOS III and IV): graduation from high school 59% and 21% respectively (p=0.006). This study highlights the high rate of severe sequelae and health care needs several years post-AHT, and emphasizes the need for extended follow-up of medical, cognitive and academic outcomes.

  15. Neurological outcome after emergency radiotherapy in MSCC of patients with non-small cell lung cancer - a prospective trial

    International Nuclear Information System (INIS)

    The aim of this trial was to investigate neurological outcome after emergency RT in MSCC of NSCLC patients with acute neurological deficit. This pilot trial was prospective, non-randomized, and monocentre, ten patients were treated from July 2012 until June 2013. After onset of neurological symptoms RT was started within 12 hours. The neurological outcome was assessed at baseline, and six weeks after RT using the ASIA Impairment Scale (AIS). The results showed an improved neurological outcome in one patient (10%), one patient (10%) had a decreased, and five patients (50%) a constant outcome after six weeks. Three patients (30%) died within the first six weeks following RT, additional 4 patients (40%) died within 4 month due to tumor progression. In this group of NSCLC patients we were able to show that emergency RT in MSCC with acute neurological deficit had no considerable benefit in neurological outcome. Therefore, short-course regime or best supportive care due to poor survival should be considered for these patients with additional distant metastases. Patients with favorable prognosis may be candidates for long-course RT

    Background Cerebrolysin, a brain-derived neuropeptide, has been shown to improve the neurological outcomes of stroke, but no study has demonstrated its effect on cerebral blood flow. This study aimed to determine the cerebrolysin impact on the neurological outcomes and cerebral blood flow. Methods In a randomized, double-blinded, placebo-controlled trial, 46 patients who had acute focal ischemic stroke were randomly assigned into two groups to receive intravenously either 30 mL of cerebrolysin diluted in normal saline daily for 10 days (n=23) or normal saline alone (n=23) adjunct to 100 mg of aspirin daily. All patients were examined using the National Institutes of Health Stroke Scale and transcranial Doppler to measure the mean flow velocity and pulsatility index (PI) of their cerebral arteries at baseline as well as on days 30, 60, and 90. Results The patients’ mean age was 60±9.7 years, and 51.2% of patients were male. The National Institutes of Health Stroke Scale was significantly lower in the cerebrolysin group compared with the placebo group on day 60 (median 10, interquartile range 9–11, P=0.008) and day 90 (median 11, interquartile range 10–13.5, P=0.001). The median of PI in the right middle cerebral artery was significantly lower in the cerebrolysin group compared with the placebo group on days 30, 60, and 90 (P<0.05). One patient in the cerebrolysin group and two patients in the placebo group died before day 30 (4.3% versus 8.7%). Conclusion Cerebrolysin can be useful to improve the neurological outcomes and the PI of middle cerebral artery in patients with acute focal ischemic stroke. PMID:25516711

    Background Neurologic deterioration (ND) after acute ischemic stroke (AIS) has been shown to result in poor outcomes. ND is thought to arise from penumbral excitotoxic cell death caused in part by leukocytic infiltration. Elevated admission peripheral leukocyte levels are associated with poor outcomes in stroke patients who suffer ND, but little is known about the dynamic changes that occur in leukocyte counts around the time of ND. We sought to determine if peripheral leukocyte levels in the days surrounding ND are correlated with poor outcomes. Methods Patients with AIS who presented to our center within 48 hours of symptom onset between July 2008 and June 2010 were retrospectively identified by chart review and screened for ND (defined as an increase in National Institutes of Health Stroke Scale score ≥2 within a 24-hour period). Patients were excluded for steroid use during hospitalization or in the month before admission and infection within the 48 hours before or after ND. Demographics, daily leukocyte counts, and poor functional outcome (modified Rankin Scale score 3–6) were investigated. Results Ninety-six of the 292 (33%) patients screened had ND. The mean age was 69.5 years; 62.5% were male and 65.6% were black. Patients with a poor functional outcome had significantly higher leukocyte and neutrophil levels 1 day before ND (P =.048 and P =.026, respectively), and on the day of ND (P =.013 and P =.007, respectively), compared to patients with good functional outcome. Conclusions Leukocytosis at the time of ND correlates with poor functional outcomes and may represent a marker of greater cerebral damage through increased parenchymal inflammation. PMID:23031742

    Full Text Available Abstract Introduction The choice of optimal treatment in traumatic brain injured (TBI patients is a challenge. The aim of this study was to verify the neurological outcome of severe TBI patients treated with decompressive craniectomy (early  24 h, compared to conservative treatment, in hospital and after 6-months. Methods A total of 186 TBI patients admitted to the ICU of the Emergency Department of a tertiary referral center (Careggi Teaching Hospital, Florence, Italy from 2005 through 2009 were retrospectively studied. Patients treated with decompressive craniectomy were divided into 2 groups: “early craniectomy group” (patients who underwent to craniectomy within the first 24 hours; and “late craniectomy group” (patients who underwent to craniectomy later than the first 24 hours. As a control group, patients whose intracranial hypertension was successfully controlled by medical treatment were included in the “no craniectomy group”. Results Groups included 41 patients who required early decompressive craniectomy, 21 patients treated with late craniectomy (7.7 days after trauma, on average, and 124 patients for whom intracranial hypertension was successfully controlled through conservative treatment. Groups were comparable in age and trauma/critical illness scores, except for a significantly higher Marshall score in early craniectomized patients. The Glasgow Outcome Scale was comparable between groups at ICU, at the time of hospital discharge and at 6 months. Conclusions In our sample, a late craniectomy in patients with refractory intracranial hypertension produced a comparable 6-months neurological outcome if compared to patients responder to standard treatment. This data must be reproduced and confirmed before considering as goal-treatment in refractory intracranial hypertension.

    Methylmercury (MeHg) is a major environmental neurotoxicant that causes damage to the central nervous system. In Japan, industrial emission of MeHg has resulted in MeHg intoxication in Minamata and Niigata, the so-called Minamata disease. Humans are exposed to MeHg derived from natural sources, primarily fish and fish predators. Therefore, MeHg continues to be an environmental risk to human health, particularly in susceptible populations that frequently consume substantial amounts of fish or fish predators such as whale. This study aimed to investigate the health effects of MeHg exposure in adults. The subjects were 194 residents (117 males, 77 females; age 20-85 years) who resided in the coastal town of Taiji, the birthplace of traditional whaling in Japan. We analyzed hair for mercury content and performed detailed neurological examinations and dietary surveys. Audiometry, magnetic resonance imaging, and electromyography were performed to diagnose neurological defects. Whole blood mercury and selenium (Se) levels were measured in 23 subjects. The geometric mean of the hair mercury levels was 14.9 μg/g. Twelve subjects revealed hair mercury levels >50 μg/g (NOAEL) set by WHO. Hair mercury levels significantly correlated with daily whale meat intake. These results suggested that residents in Taiji were highly exposed to MeHg by ingesting MeHg-contaminated whale meat. Multivariate regression analysis demonstrated no significant correlations between hair mercury levels and neurological outcomes, whereas some of the findings significantly correlated with age. A significantly positive correlation between whole blood mercury and Se levels was observed and the whole blood mercury/Se molar ratios of all subjects were effects of MeHg exposure in this study.

    Significant progress has been made in image-guided surgery (IGS) over the last few decades. IGS can be effectively applied to spinal instrumentation surgery. In the present study, we focused our attention on the feasibility and safety of image-guided spine stabilization for traumatic or osteoporotic spine injury. The IGS spine fixation with or without minimally invasive surgery (MIS) techniques such as percutaneous screw placement, balloon kyphoplasty (BKP), or vertebroplasty (VP) were accomplished in 80 patients with traumatic or osteoprotic spine injury between 2007 and 2015. The injured vertebral levels included the following: cervical spine, 41; thoracic spine, 22; and lumbar spine, 17. Neurological condition before and after surgery was assessed using the American Spinal Injury Association Impairment Scale (AIS). A total of 419 pedicle, lateral mass, or laminar screws were placed, and 399 screws (95.2%) were found to be placed correctly based on postoperative computed tomography scan. Although 20 screws (4.8%) were found to be unexpectedly placed incorrectly, no neural or vascular complications closely associated with screw placement were encountered. Neurological outcomes appeared to be acceptable or successful based on AIS. The IGS is a promising technique that can improve the accuracy of screw placement and reduce potential injury to critical neurovascular structures. The integration of MIS and IGS has proved feasible and safe in the treatment of traumatic or osteoporotic spine injury, although a thorough knowledge of surgical anatomy, spine biomechanics, and basic technique remain the most essential aspects for a successful surgery.

    To analyse the sequential sonographic findings of cystic PVL and to evaluate relationship between sonographic grading of PVL and patterns of neurologic outcomes. Authors have retrospectively analysed the sequential sonographic findings of 36 cases of PVL in the preterm neonates. Initial sonographic features done within 3 days of life were divided into 3 patients such as normal, localized, and diffuse hyperechogenic flare. Grading of PVL confirmed by follow-up studies was classified as involvement of one lobe (grade 1), two lobes (grade 2) and more than extent of grade 2 (grade 3). The relationship between sonographic grading of leukomalacia and later neurologic outcomes were also analysed. Initial sonographic patterns according to grading of PVL were normal pattern in seven of nine (77.8%) of grade 1, diffuse hyperechogenic flares in five of eight cases of grade 2 and in 13 of 16 cases of grade 3. There was a significant difference between the grades and frequency of pattern of diffuse hyperechoic flare (p=0.021). Average detection timing of cystic PVL was 38.4{+-}18.9 days in grade 1, 29.8{+-}14 days in grade 2, and 19.1{+-}5.6 days in grade 3 with a significant statistical difference between the detection time and grades (p=0.037). Cerebral palsy has occurred in 62.5% of grade 1 and 100% of grade 2 and grade 3 (p=0.043). Frequency of spastic quadriplegia was higher in grade 3 (76.5%) than in grade 1 (25%) and grade 2 (12.5%) (p=0.001). Most of grade 1 cystic PVL revealed normal pattern of white matter echogenicity in initial ultrasonography and needed follow up examination over one month period. Spastic quadriplegia occured mainly in patients with grade 3 cystic PVL.

    Full Text Available Abstract: The Zika virus epidemic that started in Brazil in 2014 has spread to >30 countries and territories in Latin America, leading to a rapid rise in the incidence of microcephalic newborns and adults with neurological complications. At the beginning of the outbreak, little was known about Zika virus morphology, genome structure, modes of transmission, and its potential to cause neurological malformations and disorders. With the advancement of basic science, discoveries of the mechanisms of strain variability, viral transfer to the fetus, and neurovirulence were published. These will certainly lead to the development of strategies to block vertical viral transmission, neuronal invasion, and pathogenesis in the near future. This paper reviews the current literature on Zika virus infections, with the aim of gaining a holistic insight into their etiology and pathogenesis. We discuss Zika virus history and epidemiology in Brazil, viral structure and taxonomy, old and newly identified transmission modes, and neurological consequences of infection.

    Fifty-one patients were included in a blind randomized study to evaluate whether the Ca-blocker nimodipine could influence cerebral blood flow (CBF) or cerebrospinal fluid pressure (CSFP) during the cerebral hypoperfusion period that follows resuscitation from cardiac arrest and to determine whether changes in CBF correlate with neurologic outcome. CBF measured 1 to 4 hours after arrest with the use of 133Xe intravenous was significantly greater with nimodipine than with placebo (27 +/- 3 versus 13 +/- 1 ml.100 g-1.min-1 at 3 hours), but with no significant difference at 24 hours. There was no clinical evidence of seriously increased CSFP in any patient in either group the first 48 hours. Mean arterial pressure was significantly lower (86 +/- 4 versus 101 +/- 4 mm Hg at 3 hours), and antiarrhythmic drugs were used significantly less frequently in the nimodipine group than in the placebo group. Twelve patients in each group eventually regained consciousness. There was no significant difference in neurologic status between the two groups at any point, and no positive correlation between CBF in the hypoperfusion period and neurologic outcome. PMID:2929976

    Birth asphyxia is a cause of neonatal death or adverse neurological sequelae. Biomarkers can be useful to clinicians in order to optimize intensive care management and communication of prognosis to parents. During perinatal adverse events, increased cortisol secretion is due to hypothalamo-pituitary-adrenal axis activation. We aimed to investigate if cortisol variations during therapeutic hypothermia are associated with neurodevelopmental outcome. We compared 18 cases (neonates with birth asphyxia) with 18 controls (healthy term newborns) and confirmed increased serum cortisol concentrations following the peri-partum adverse event. Among cases, we stratified patients according to neurological outcome at 18 months (group A - good; group B - adverse) and found that after 24 h of therapeutic hypothermia serum cortisol concentration was significantly lower in group A vs group B (28.7 ng/mL vs 344 ng/mL, *p = 0.01). In group B serum, cortisol concentration decreased more gradually during therapeutic hypothermia. We conclude that monitoring serum cortisol concentration during neonatal therapeutic hypothermia can add information to clinical evaluation of neonates with birth asphyxia; cortisol values after the first 24 h of hypothermia can be a biomarker associated with neurodevelopmental outcome at 18 months of age.

    Nathalie K S de Vries

    Full Text Available BACKGROUND: Use of selective serotonin reuptake inhibitors (SSRI during pregnancy is common while the effect on the infant's neurological outcome is unknown. Our objective was to determine the effects of prenatal SSRI-exposure on the infants' neurological functioning, adjusted for maternal mental health. METHODS: A prospective observational study from May 2007 to April 2010. The study groups comprised 63 SSRI-exposed infants (SSRI group and 44 non-exposed infants (non-SSRI group. Maternal depression and anxiety were measured using questionnaires. The main outcome measures during the first week after birth and at three to four months were the quality of the infants' general movements (GMs according to Prechtl and a detailed motor optimality score. We calculated odds ratios (ORs and 95% confidence intervals (CIs for abnormal GM quality in the SSRI and non-SSRI groups, and adjusted for maternal depression, anxiety, and other confounders. The study was registered under 53506435 in the ISRCTN. FINDINGS: All infants were born around term. During the first week, abnormal GMs occurred more frequently in the SSRI group than in the non-SSRI group (59% versus 33% and the median MOS was lower (13 versus 18. The OR for abnormal GMs in the SSRI versus the non-SSRI group was 3.0 (95% CI, 1.3 to 6.9 and increased after adjustment for confounders. At three to four months, more SSRI-exposed infants had monotonous movements (48% versus 20% with lower median MOSs (26 versus 28. The OR for monotonous movements was 3.5 (95% CI, 1.5 to 8.6 and increased after adjusting for confounders. INTERPRETATION: Prenatal exposure to SSRI had an adverse effect on early neurological functioning as reflected by GM quality, irrespective of maternal depression and anxiety, and other confounders. Physicians should take this into account in consultation with parents.

  14. Long time to diagnosis of medulloblastoma in children is not associated with decreased survival or with worse neurological outcome.

    Directory of Open Access Journals (Sweden)

    Jean-Francois Brasme

    Full Text Available BACKGROUND: The long time to diagnosis of medulloblastoma, one of the most frequent brain tumors in children, is the source of painful remorse and sometimes lawsuits. We analyzed its consequences for tumor stage, survival, and sequelae. PATIENTS AND METHODS: This retrospective population-based cohort study included all cases of pediatric medulloblastoma from a region of France between 1990 and 2005. We collected the demographic, clinical, and tumor data and analyzed the relations between the interval from symptom onset until diagnosis, initial disease stage, survival, and neuropsychological and neurological outcome. RESULTS: The median interval from symptom onset until diagnosis for the 166 cases was 65 days (interquartile range 31-121, range 3-457. A long interval (defined as longer than the median was associated with a lower frequency of metastasis in the univariate and multivariate analyses and with a larger tumor volume, desmoplastic histology, and longer survival in the univariate analysis, but not after adjustment for confounding factors. The time to diagnosis was significantly associated with IQ score among survivors. No significant relation was found between the time to diagnosis and neurological disability. In the 62 patients with metastases, a long prediagnosis interval was associated with a higher T stage, infiltration of the fourth ventricle floor, and incomplete surgical resection; it nonetheless did not influence survival significantly in this subgroup. CONCLUSIONS: We found complex and often inverse relations between time to diagnosis of medulloblastoma in children and initial severity factors, survival, and neuropsychological and neurological outcome. This interval appears due more to the nature of the tumor and its progression than to parental or medical factors. These conclusions should be taken into account in the information provided to parents and in expert assessments produced for malpractice claims.

    The aim of this paper is to provide a concise summary of findings from outcome studies in early-treated phenylketonuria (PKU). The paper should not be considered as an extensive review of the many different outcome measures that have been used in PKU-research, but as an attempt to integrate such findings so that they will be of additional value for day to day monitoring of PKU-patients and may direct future research to fill the present gaps of knowledge. Neurological, neuropsychological, neurophysiological, neuroimaging, quality of life, and psychosocial findings will be discussed in the context of their potential contributions to lifelong follow-up and treatment of PKU-patients being summarized in statements.

    The main complications of open tibiotalocalcaneal arthrodesis are wound healing disorders and nonunion. Our hypothesis was that arthroscopy and interlocking intramedullary nailing decrease these complications. We retrospectively reviewed six patients (mean age: 58 years; mean preoperative Kitaoka score: 51/100) having undergone arthroscopic tibiotalocalcaneal arthrodesis with retrograde intramedullary nailing between January and November 2011 for equinus deformity of the hindfoot and subtalar instability of neurological origin. Postoperative pain disappeared completely in four cases, one patient presented some pain associated with projection of the proximal locking screw head under the skin and the remaining patient presented fibular tendinitis that resolved after infiltration of anti-inflammatory drugs. The mean postoperative Kitaoka score was 64/100. None of the patients presented any wound healing complications or nonunion. The observed incidence of wound complications and bone consolidation disorders after tibiotalocalcaneal arthrodesis was lower than the ones reported for open tibiotalocalcaneal arthrodesis.

    Objective Long-term, high-level exposure to manganese (Mn) is associated with impaired central nervous system (CNS) function. We quantitatively explored relations between low-level Mn exposure and selected neurological outcomes in a longitudinal inception cohort of asymptomatic welder trainees. Methods Welders with no previous occupational Mn exposure were observed approximately every three months over the course of the five-quarter traineeship. Fifty-six welders were assessed for motor function using the Unified Parkinson Disease Rating Scale motor subsection part 3 (UPDRS3) and Grooved Pegboard tests. A subset of 17 also had MRI scans to assess T1-weighted indices. Personal exposure to Mn in welding fume was quantitatively assessed during the study period using a mixed model to obtain estimates of subject-specific exposure level by welding type. These estimates were summed to estimate cumulative exposure at the time of each neurological outcome test. Results When adjusting for possible learning effects, there were no associations between cumulative exposure and UPDRS3 score or Grooved Pegboard time. T1-weighted indices of the basal ganglia (caudate, anterior putamen, posterior putamen, and combined basal ganglia, but not the pallidal index) exhibited statistically significant increases in signal intensity in relation to increased cumulative Mn exposure. Conclusions This study demonstrates that T1-weighted changes can be detected in the brain even at very low levels of exposure among humans before any clinically evident deficits. This suggests that with continued follow-up we could identify a T1 threshold of toxicity at which clinical symptoms begin to manifest. PMID:25380186

    The fields of neurodegenerative disease and dementia research have grown considerably in the last several decades. Due to tremendous efforts of basic and clinical research scientists, we know a great deal about dementia risk factors and have multiple treatment options. Clinician recognition of cognitive impairment has increased considerably, national policies which support screening for and documenting cognitive dysfunction now exist, and public awareness of neurodegenerative disease has never been greater. These conditions promote (and demand) the growth of translational epidemiology and health services research, which focuses on examining outcomes in groups of individuals as a function of health care experiences. This review discusses the use of administrative data to answer health care outcomes and disparities questions in dementia. Of particular interest are publically available datasets that contain varying amounts of diagnostic, clinical, pharmacy, and patient information. Methodological challenges that are frequently encountered and must be understood to minimize biased inference are also discussed. PMID:26423637

    Full Text Available The pursuit of targeting multiple pathways in the ischemic cascade of cerebral stroke is a promising treatment option. We examined the regenerative potential of conditioned medium derived from rat and human apoptotic mononuclear cells (MNC, rMNCapo sec and hMNCapo sec, in experimental stroke. We performed middle cerebral artery occlusion on Wistar rats and administered apoptotic MNC-secretomes intraperitoneally in two experimental settings. Ischemic lesion volumes were determined 48 hours after cerebral ischemia. Neurological evaluations were performed after 6, 24 and 48 hours. Immunoblots were conducted to analyze neuroprotective signal-transduction in human primary glia cells and neurons. Neuronal sprouting assays were performed and neurotrophic factors in both hMNCapo sec and rat plasma were quantified using ELISA. Administration of rat as well as human apoptotic MNC-secretomes significantly reduced ischemic lesion volumes by 36% and 37%, respectively. Neurological examinations revealed improvement after stroke in both treatment groups. Co-incubation of human astrocytes, Schwann cells and neurons with hMNCapo sec resulted in activation of several signaling cascades associated with the regulation of cytoprotective gene products and enhanced neuronal sprouting in vitro. Analysis of neurotrophic factors in hMNCapo sec and rat plasma revealed high levels of brain derived neurotrophic factor (BDNF. Our data indicate that apoptotic MNC-secretomes elicit neuroprotective effects on rats that have undergone ischemic stroke.

    Full Text Available The skeletal muscle develops various degrees of atrophy and metabolic dysfunction following nerve injury. Neurotrophic factors are essential for muscle regeneration. Human amniotic fluid derived stem cells (AFS have the potential to secrete various neurotrophic factors necessary for nerve regeneration. In the present study, we assess the outcome of neurological function by intramuscular injection of AFS in a muscle denervation and nerve anastomosis model.Seventy two Sprague-Dawley rats weighing 200-250 gm were enrolled in this study. Muscle denervation model was conducted by transverse resection of a sciatic nerve with the proximal end sutured into the gluteal muscle. The nerve anastomosis model was performed by transverse resection of the sciatic nerve followed by four stitches reconnection. These animals were allocated to three groups: control, electrical muscle stimulation, and AFS groups.NT-3 (Neurotrophin 3, BDNF (Brain derived neurotrophic factor, CNTF (Ciliary neurotrophic factor, and GDNF (Glia cell line derived neurotrophic factor were highly expressed in AFS cells and supernatant of culture medium. Intra-muscular injection of AFS exerted significant expression of several neurotrophic factors over the distal end of nerve and denervated muscle. AFS caused high expression of Bcl-2 in denervated muscle with a reciprocal decrease of Bad and Bax. AFS preserved the muscle morphology with high expression of desmin and acetylcholine receptors. Up to two months, AFS produced significant improvement in electrophysiological study and neurological functions such as SFI (sciatic nerve function index and Catwalk gait analysis. There was also significant preservation of the number of anterior horn cells and increased nerve myelination as well as muscle morphology.Intramuscular injection of AFS can protect muscle apoptosis and likely does so through the secretion of various neurotrophic factors. This protection furthermore improves the nerve

    To evaluate antiretroviral (ARV) drug exposure and other factors during pregnancy that may increase the risk of neurologic conditions (NCs) in HIV-exposed/uninfected (HEU) infants. A prospective cohort study was conducted at 24 clinical sites in Latin America and the Caribbean. Data on maternal demographics, health, HIV disease status, and ARV use during pregnancy were collected. Infant data included measurement of head circumference after birth and reported medical diagnoses at birth, 6-12 weeks, and 6 months. Only infants with maternal exposure to combination ARV therapy (cART) (≥3 drugs from ≥2 drug classes) during pregnancy were included. Microcephaly, defined as head circumference for age z-score less than -2, and NC were evaluated for their association with covariates, including individual ARVs, using bivariable and logistic regression analyses. From 2002 to 2009, 1,400 HEU infants met study inclusion criteria. At least one NC was reported in 134 (9.6%; 95% confidence interval [CI]: 8.1-11.2), microcephaly in 105 (7.5%; 95% CI: 6.2-9.0), and specific neurologic diagnoses in 33 (2.4%; 95% CI: 1.6-3.3) HEU infants. Microcephaly and NC were not significantly associated with any specific ARV analyzed (p > 0.05). Covariates associated with increased odds of NC included male sex (odds ratio [OR] = 1.9; 95% CI: 1.3-2.8), birth weight <2.5 kg (OR = 3.1; 95% CI: 2.1-4.8), 1-min Apgar score <7 (OR = 2.5; 95% CI: 1.4-4.4), and infant infections (OR = 2.5; 95% CI: 1.5-4.1). No ARV investigated was associated with adverse neurologic outcomes. Continued investigation of such associations may be warranted as new ARVs are used during pregnancy and cART exposure during the first trimester becomes increasingly common. PMID:26879281

    BACKGROUND: Midazolam and propofol are sedative agents commonly administered to patients with brain injury. We compared plasma concentrations of glial cell S100beta protein and nitric oxide (NO) between patients who received midazolam and those who received propofol sedation after severe brain injury, and investigated the association between S100beta and NO concentrations and neurological outcome. DESIGN: 28 patients with severe head injury (Glasgow Coma Score <9) who required sedation and ventilation were randomly assigned to receive midazolam (n =15) or propofol (n = 13) based sedation. Blood samples were drawn daily for 5 days for estimation of S100beta and NO concentrations. Neurological outcome was assessed 3 months later as good (Glasgow Outcome Score [GOS], 4-5) or poor (GOS, 1-3). RESULTS: A good neurological outcome was observed in 8\\/15 patients (53%) in the midazolam group and 7\\/13 patients (54%) in the propofol group. Patients with a poor outcome had higher serum S100beta concentrations on ICU admission and on Days 1-4 in the ICU than those with a good outcome (mean [SD] on Day 1, 0.99 [0.81] v 0.41 [0.4] microg\\/L; Day 2, 0.80 [0.81] v 0.41 [0.24] microg\\/L; Day 3, 0.52 [0.55] v 0.24 [0.25] microg\\/L; and Day 4, 0.54 [0.43] v 0.24 [0.35] microg\\/L; P<0.05). There was no significant difference on Day 5. Plasma NO concentrations were not associated with outcome. In subgroup analysis, there was no difference in S100beta and NO concentrations between patients with a good outcome versus those with a poor outcome in either the midazolam or propofol group. CONCLUSIONS: Plasma concentrations of markers of neurological injury in patients with severe head injury were similar in those who received midazolam sedation and those who received propofol. Patients who had a poor neurological outcome at 3 months had consistently higher serum S100beta concentrations during the initial 4 days after injury than patients who had a good outcome.

    Sex differences are well known in cerebral ischemia and may impact the effect of stroke treatments. In male rats, the MEK1/2 inhibitor U0126 reduces ischemia-induced endothelin type B (ETB) receptor upregulation, infarct size and improves acute neurologic function after experimental stroke. However...... occlusion (tMCAO, 120 minutes) was induced in female Wistar rats, with U0126 (30 mg/kg intraperitoneally) or vehicle administered at 0 and 24 hours of reperfusion, or with no treatment. Infarct volumes were determined and neurologic function was assessed by 6-point and 28-point neuroscores. ETB receptor......-mediated contraction was studied with myograph and protein expression with immunohistochemistry. In vitro organ culture and tMCAO resulted in vascular ETB receptor upregulation and activation of ERK1/2 that was prevented by U0126. Although no effect on infarct size, U0126 improved the long-term neurologic function...

    Full Text Available Aims and objectives: To evaluate the role of magnetic resonance imaging (MRI as a non-invasive diagnostic tool in patients with acute and chronic spinal trauma and to compare and correlate the MRI findings with those of patients′ clinical profile and neurological outcome according to ASIA impairment scale to assess prognostic and clinical value of MRI. Materials and Methods: Sixty two patients of spinal trauma formed the study group in a prospective fashion. The patients undergoing MR imaging and magnetic resonance images were analyzed and correlated with findings on neurological examination according to American Spinal Injury Association (ASIA impairment scale (AIS at the time of MRI examination and subsequently at sub-acute interval to assess neurological outcome. Statistical Analysis : Sample profile was described in terms of 95% confidence limit and proportion. To describe strength of association between extent of spinal cord injury and outcome, odd′s ratio, bivariate and multi variant analysis, was used. Pearson′s chi square (χ 2 statistics was applied to test the association between two categorical variables. Data were analyzed using statistical software package, STATA 9.2 and the difference was considered to be significant if ′P′ value was <0.05. Observation and Results: The cord edema without hemorrhage was the most common MR finding (41.5%. The others were sizable focus of hemorrhage within the cord (33%, epidural hematoma (5.0%, and normal cord (26%. Majority of MR findings correlated well with clinical profile of the patient according to ASIA impairment scale. This study demonstrated that patients with presence of sizable focus of haemorrhage had larger cord edema and more severe grade of initial ASIA impairment scale( AIS with poor recovery at follow up (P=0.032.Improvement in upper extremity was more than lower extremity. Severe cord compression was also associated with poor neurological outcome; however it was not

    The management of refractory cardiac arrest during invasive coronary procedures has substantial logistical challenges and is typically associated with disappointing outcomes. We describe the case of a young woman with recalcitrant ventricular fibrillation due to acute anterior ST-elevation myocardial infarction caused by occlusion of her proximal left anterior descending artery. Survival without neurological deficit or organ failure was achieved following primary percutaneous reperfusion and a total of 52 min of intra-procedural chest compression support, made possible by the use of an automated chest compression device.

  12. Periventricular leukomalacia with late-onset circulatory dysfunction of premature infants. Correlation with severity of magnetic resonance imaging findings and neurological outcomes

    International Nuclear Information System (INIS)

    The incidence of late-onset circulatory dysfunction (LCD) of premature infants, which is characterized by sudden hypotension and oliguria, has recently increased in Japan. This condition suddenly occurs after several days of age without obvious causes in preterm infants with stable respiration and circulation. Intravenous steroids frequently improve the hypotension. The main problem with LCD is the subsequent and frequent onset of periventricular leukomalacia (PVL), and neurological development appears to be worse in PVL patients with LCD than those without LCD. The aim of this study was to determine whether the severity of magnetic resonance imaging (MRI) findings and neurological outcomes differ between infants who developed PVL after LCD and those who developed PVL without LCD. We retrospectively studied preterm infants who were delivered at less than 33 weeks of gestation between the years 2000 and 2003. During the study period, 10 and 26 infants developed PVL with and without LCD, respectively. The incidence of severe or moderate MRI findings was significantly higher in PVL patients with LCD (100%) than those without LCD (50%; p<0.05). The incidence of severe cerebral palsy was 88% in PVL infants with LCD and 43% in PVL infants without LCD (p<0.05). Moreover, the incidence of visual disorders was significantly higher in PVL infants with LCD (63%) than those without LCD (9%; p<0.01). In conclusion, neurological outcomes are worse in preterm infants who develop PVL with LCD than those without LCD, which is well correlated to the severity judged by MRI findings. (author)

    Full Text Available Although fever and infection have been implicated in the causation of delayed neurological deficits (DND and poor outcome after aneurysmal subarachnoid hemorrhage (SAH, the relationship between these two often related events has not been extensively studied. We reviewed these events through of our retrospective database of patients with SAH. Multivariate logistic regression was used to determine independent predictors of DND and poor outcome. A total of 186 patients were analyzed. DND was noted in 76 patients (45%. Fever was recorded in 102 patients (55%; infection was noted in 87 patients (47%. A patient with one infection was more likely to experience DND compared to a patient with no infections (adjusted OR 3.73, 95% CI 1.62, 8.59. For those with more than two infections the likelihood of DND was even greater (adjusted OR 4.24, 95% CI 1.55, 11.56. Patients with 1-2 days of fever were less likely to have a favorable outcome when compared to their counterparts with no fever (adjusted OR 0.19, 95% CI 0.06, 0.62. This trend worsened as the number of days febrile increased. These data suggest that the presence of infection is associated with DND, but that fever may have a stronger independent association with overall outcome.

    Full Text Available Objective To explore the correlation between thyroid hormone levels in patients with acute ischemic stroke and the severity of disease and short-term prognosis. Methods According to the level of serum total triiodothyronine (TT3, 98 patients who presented first acute ischemic stroke and without history of thyroid abnormality were divided into low TT3 group and normal TT3 group. Thyroid hormone levels and neurological function defect of those patients were tested, and their neural functional recovery after 3 months was evaluated.  Results Low TT3 group had more severe neural function defect compared to normal TT3 group (χ2 = 58.134, P = 0.000. There were no significant differences on total thyroxine (TT4; t = 1.636, P = 0.105 and thyroid stimulating hormone (TSH; t = 1.059, P = 0.292 between 2 groups. There was a significantly negative correlation between TT3 levels and National Insititute of Health Stroke Scale (NIHSS score on admission (r = -0.672, P = 0.000.

    Directory of Open Access Journals (Sweden)

    Pericles Calias

    Full Text Available A major challenge for the treatment of many central nervous system (CNS disorders is the lack of convenient and effective methods for delivering biological agents to the brain. Mucopolysaccharidosis II (Hunter syndrome is a rare inherited lysosomal storage disorder resulting from a deficiency of iduronate-2-sulfatase (I2S. I2S is a large, highly glycosylated enzyme. Intravenous administration is not likely to be an effective therapy for disease-related neurological outcomes that require enzyme access to the brain cells, in particular neurons and oligodendrocytes. We demonstrate that intracerebroventricular and lumbar intrathecal administration of recombinant I2S in dogs and nonhuman primates resulted in widespread enzyme distribution in the brain parenchyma, including remarkable deposition in the lysosomes of both neurons and oligodendrocytes. Lumbar intrathecal administration also resulted in enzyme delivery to the spinal cord, whereas little enzyme was detected there after intraventricular administration. Mucopolysaccharidosis II model is available in mice. Lumbar administration of recombinant I2S to enzyme deficient animals reduced the storage of glycosaminoglycans in both superficial and deep brain tissues, with concurrent morphological improvements. The observed patterns of enzyme transport from cerebrospinal fluid to the CNS tissues and the resultant biological activity (a warrant further investigation of intrathecal delivery of I2S via lumbar catheter as an experimental treatment for the neurological symptoms of Hunter syndrome and (b may have broader implications for CNS treatment with biopharmaceuticals.

  17. Outcome of low birth weight infants who were afflicted with abnormal neurological findings during thier first year of age, 3

    International Nuclear Information System (INIS)

    The relationship between long-term prognoses and growth patterns of brain volume were studied in 138 low birth weight infants who were afflicted with abnormal CNS symptoms within 1 year after birth. The brain volume was estimated by head circumferance and CT measurement. In the preterm infants, whose final diagnoses were normal or mildly handicapped, the brain volume growth pattern was similar to that in the normal standard group and reached to the lower limit of standard values within 1 year. On the contrary, in the infants with moderate or severe handicaps, the growth of brain volume was so limited that significant deviation from the normal standard was noted at 1 year of age. These findings suggest that the growth pattern of the brain during the first year of life would be very important to expect neurological prognoses. In the infants with intrauterine growth retardation, their growth of head circumference after birth was retarded. Especially children with microcephalia at birth revealed significant retardation. It is speculated that the brain growth after birth was strongly influenced by the growth in utero. (author)

  18. Normal neurologic and developmental outcome after an accidental intravenous infusion of expressed breast milk in a neonate.

    Here we describe a premature male infant who was accidentally given 10 mL of expressed breast milk intravenously over a 3.5-hour period. Having survived this event with supportive care, this boy was attending regular school with no obvious neurologic or learning difficulties at 6 years of age. In 1998, after a query on an e-mail discussion group for health care providers in neonatology (NICU-net), we were informed of 8 similar events that proved fatal in 3 infants. A root-cause analysis revealed that accidental intravenous administration of breast milk or formula can be avoided by the use of color-coded enteral-administration sets with Luer connections that are not compatible with intravenous cannulas. The addition of methylene blue to feeds, or bolus enteral feeds (instead of continuous gastric feedings), may also help prevent such errors. These cases show the value of gathering information about rare but important events through a neonatal network. In addition, they confirm that prevention of medical error should focus on faulty systems rather than faulty people.

    Background The risk of clinical deterioration still exists in the acute phase despite the fact that patients with minor stroke may display less severe symptoms.The impact of this clinical deterioration on long-term outcomes is unknown.We characterized the clinical features of neurological deterioration (ND) in the acute phase of minor ischemic stroke (MIS) and investigated its impact on mid-and long-term outcomes.Methods This was a multi-centered,prospective clinical study involving patients with MIS (the National Institutes of Health Stroke Scale,NIHSS <3) recruited from the China National Stroke Registry.Patients were included who had been hospitalized within 24 hours of stroke onset.Baseline characteristics,complication rates during hospitalization,etiology of stroke,as well as 3-,6-,and 12-month post-stroke outcomes were compared between patients with and without ND during the acute phase.Results A number of 368 (15.2%) out of 2424 patients included in the study exhibited ND in the acute phase.Compared to patients without ND,patients with ND had longer hospital stay,increased rate of baseline diabetes,and multiple complications.Multivariate Logistic regression indicated that ND in acute phase was an independent factor predictive of increased dependence (adjusted odds ratio =5.20,95% Cl,3.51-7.70,P <0.001) at 12-month post-stroke.Conclusions The risk of ND in the acute phase is high in patients with MIS.ND in the acute phase is an independent predictor for poor outcomes at 12 months post-stroke onset.

    Neurological system assessment is an important skill for the orthopaedic nurse because the nervous system has such an overlap with the musculoskeletal system. Nurses whose scope of practice includes such advanced evaluation, e.g. nurse practitioners, may conduct the examination described here but the information will also be useful for nurses caring for patients who have abnormal neurological assessment findings. Within the context of orthopaedic physical assessment, possible neurological findings are evaluated as they complement the patient's history and the examiner's findings. Specific neurological assessment is integral to diagnosis of some orthopaedic conditions such as carpal tunnel syndrome. In other situations such as crushing injury to the extremities, there is high risk of associated neurological or neurovascular injury. These patients need anticipatory examination and monitoring to prevent complications. This article describes a basic neurological assessment; emphasis is on sensory and motor findings that may overlap with an orthopaedic presentation. The orthopaedic nurse may incorporate all the testing covered here or choose those parts that further elucidate specific diagnostic questions suggested by the patient's history, general evaluation and focused musculoskeletal examination. Abnormal findings help to suggest further testing, consultation with colleagues or referral to a specialist. PMID:27118633

    Traumatic brain injury (TBI) is an international health concern often resulting in chronic neurological abnormalities, including cognitive deficits, emotional disturbances, and motor impairments. An anti-CD11d monoclonal antibody that blocks the CD11d/CD18 integrin and vascular cell adhesion molecule (VCAM)-1 interaction following experimental spinal cord injury improves functional recovery, while reducing the intraspinal number of neutrophils and macrophages, oxidative activity, and tissue damage. Since the mechanisms of secondary injury in the brain and spinal cord are similar, we designed a study to evaluate fully the effects of anti-CD11d treatment after a moderate lateral fluid percussion TBI in the rat. Rats were treated at 2 h after TBI with either the anti-CD11d antibody or an isotype-matched control antibody 1B7, and both short (24- to 72-h) and long (4-week) recovery periods were examined. The anti-CD11d integrin treatment reduced neutrophil and macrophage levels in the injured brain, with concomitant reductions in lipid peroxidation, astrocyte activation, amyloid precursor protein accumulation, and neuronal loss. The reduced neuroinflammation seen in anti-CD11d-treated rats correlated with improved performance on a number of behavioral tests. At 24 h, the anti-CD11d group performed significantly better than the 1B7 controls on several water maze measures of spatial cognition. At 4 weeks post-injury the anti-CD11d-treated rats had better sensorimotor function as assessed by the beam task, and reduced anxiety-like behaviors, as evidenced by elevated-plus maze testing, compared to 1B7 controls. These findings suggest that neuroinflammation is associated with behavioral deficits after TBI, and that anti-CD11d antibody treatment is a viable strategy to improve neurological outcomes after TBI.

    6 000-ms intervals. Current dosage was 20–40 mA. The electrical stimulation was given 6 minutes/session, once a day, and 20 days were regarded as one treatment cycle. ② A TMA-A double-frequent mild-hot therapeutic instrument was used on patients in the decimeter wave group after neurolysis. The therapeutic program was adapted to the early and middle-late phase. In the early phase, the decimeter wave was 10–15 W, 10 minutes/session, once a day; in the middle-late phase, the decimeter wave was 10–30 W, 20 minutes/session, once a day. Twenty days were regarded as one treatment cycle. ③ Patients in the compound physical factor group following neurolysis were treated the same as the decimeter wave group and electrical stimulation group, respectively. The treatment was performed once a day, and 20 days were regarded as one course. ④ Patients in the control group were not administered any physical treatment. MAIN OUTCOME MEASURES: Therapeutic efficacy was comprehensively evaluated based on motor and sensory evaluation criteria (set by Subassociation of Hand Surgery, Chinese Medical Association) at 1, 2, and 3 months after surgery, as well as changes in the electromyogram before and after operation. RESULTS: All 124 patients with peripheral nerve entrapment syndrome were included in the final analysis. One month after surgery, fineness rates in the electrical stimulation group, decimeter wave group, and compound physical factor group were not significantly different from those in the control group (P > 0.05). There was also no significant difference between the electrical stimulation group, decimeter wave group, and compound physical factor group (P > 0.05). Two months after surgery, fineness rates in the electrical stimulation group and decimeter wave group were not significantly different from the control group (P > 0.05). However, fineness rates were higher in the compound physical factor group compared to the other three groups (P 0.05). Three months after

    Full Text Available Background: Ventilator-associated pneumonia (VAP is a common complication with endotracheal intubation. The occurrence of VAP results in significant mortality and morbidity. Earlier studies have shown reduction in the incidence of VAP with subglottic secretion drainage. The incidence of VAP in neurologically injured patients is higher and can impact the neurological outcome. This study aimed to compare the incidence of VAP with standard endotracheal tube (SETT and suction above cuff endotracheal tube (SACETT in neurologically ill patients and its impact on clinical outcome. Methods: Fifty-four patients with neurological illnesses aged ≥18 years and requiring intubation and/or ventilation and anticipated to remain on ETT for ≥48 h were randomized to receive either SETT or SACETT. All the VAP preventive measures were similar between two groups except for the difference in type of tube. Results: The data of 50 patients were analyzed. The incidence of clinical VAP was 20% in SETT group and 12% in SACETT group; (P = 0.70. The incidence of microbiological VAP was higher in the SETT group (52% as compared to SACETT group (44% but not statistically significant; (P = 0.78. There was no difference between the two groups for measured outcomes such as duration of intubation, mechanical ventilation, and Intensive Care Unit stay. Conclusions: In this pilot study in neurological population, a there was no significant difference in incidence of clinical and microbiological VAP was seen between SETT and SACETT, when other strategies for VAP prevention were similar. Other outcomes were similar with use of either tube for intubation.

  7. Cranial ultrasonography and transfontanellar Doppler in premature neonates (24–32 weeks of gestation): Dynamic evolution and association with a severe adverse neurological outcome at hospital discharge in the Aquitaine cohort, 2003–2005

    International Nuclear Information System (INIS)

    Objective: To correlate the short-term neurological outcome of early cerebral abnormalities using cranial ultrasonography (US) in premature newborns at their hospital discharge. Methods: Each newborn born < 33 weeks of gestational age (GA) included in a prospective cohort benefited of 3 US: two early in the first week of life (D3 and D8) and one later (Months 1–2) standardized US pulsed Doppler. A US abnormality was ≥one morphologic abnormality (moderate: intra-ventricular hemorrhage (IVH) grades 1–2; severe: IVH 3–4, periventricular leukomalacia, persistent flares). Correlates of having a severe adverse neurological outcome were analyzed using a stepwise backward logistic regression adjusted model with gestational age, early cerebral abnormality at Days 3–8, velocity and with variables with correlation probabilities with p < 0.25 in the univariate analysis among occurring co-morbidity events previously defined. Two adjusted logistic regression analyses were conducted including or not velocity data because of missing information. Results: Among 452 premature included, 11.3% did not have an early US, 74.8% had a normal early US, 13.9% ≥one early morphological US abnormality (10.0% moderate, 3.9% severe). At hospital discharge, 40% were still alive with a normal late US, 33% alive with ≥one late morphological US abnormality (10% moderate, 23% severe), and 10% died. Adjusted correlates of a late US severe abnormality or a neurological related death at hospital discharge were: early US abnormality (aOR: 8.7, 95% CI: 2.3–33.6), GA < 29 weeks (aOR: 2.8 95% CI: 1.4–5.4). Conclusion: This study shows that early US morphological abnormalities increase significantly when the GA decreases and is highly predictive of the occurrence of a further late US severe abnormality or neurological related death at hospital discharge

    Objective: To correlate the short-term neurological outcome of early cerebral abnormalities using cranial ultrasonography (US) in premature newborns at their hospital discharge. Methods: Each newborn born < 33 weeks of gestational age (GA) included in a prospective cohort benefited of 3 US: two early in the first week of life (D3 and D8) and one later (Months 1–2) standardized US pulsed Doppler. A US abnormality was ≥one morphologic abnormality (moderate: intra-ventricular hemorrhage (IVH) grades 1–2; severe: IVH 3–4, periventricular leukomalacia, persistent flares). Correlates of having a severe adverse neurological outcome were analyzed using a stepwise backward logistic regression adjusted model with gestational age, early cerebral abnormality at Days 3–8, velocity and with variables with correlation probabilities with p < 0.25 in the univariate analysis among occurring co-morbidity events previously defined. Two adjusted logistic regression analyses were conducted including or not velocity data because of missing information. Results: Among 452 premature included, 11.3% did not have an early US, 74.8% had a normal early US, 13.9% ≥one early morphological US abnormality (10.0% moderate, 3.9% severe). At hospital discharge, 40% were still alive with a normal late US, 33% alive with ≥one late morphological US abnormality (10% moderate, 23% severe), and 10% died. Adjusted correlates of a late US severe abnormality or a neurological related death at hospital discharge were: early US abnormality (aOR: 8.7, 95% CI: 2.3–33.6), GA < 29 weeks (aOR: 2.8 95% CI: 1.4–5.4). Conclusion: This study shows that early US morphological abnormalities increase significantly when the GA decreases and is highly predictive of the occurrence of a further late US severe abnormality or neurological related death at hospital discharge.

  9. Suppression of acute proinflammatory cytokine and chemokine upregulation by post-injury administration of a novel small molecule improves long-term neurologic outcome in a mouse model of traumatic brain injury

    Full Text Available Abstract Background Traumatic brain injury (TBI with its associated morbidity is a major area of unmet medical need that lacks effective therapies. TBI initiates a neuroinflammatory cascade characterized by activation of astrocytes and microglia, and increased production of immune mediators including proinflammatory cytokines and chemokines. This inflammatory response contributes both to the acute pathologic processes following TBI including cerebral edema, in addition to longer-term neuronal damage and cognitive impairment. However, activated glia also play a neuroprotective and reparative role in recovery from injury. Thus, potential therapeutic strategies targeting the neuroinflammatory cascade must use careful dosing considerations, such as amount of drug and timing of administration post injury, in order not to interfere with the reparative contribution of activated glia. Methods We tested the hypothesis that attenuation of the acute increase in proinflammatory cytokines and chemokines following TBI would decrease neurologic injury and improve functional neurologic outcome. We used the small molecule experimental therapeutic, Minozac (Mzc, to suppress TBI-induced up-regulation of glial activation and proinflammatory cytokines back towards basal levels. Mzc was administered in a clinically relevant time window post-injury in a murine closed-skull, cortical impact model of TBI. Mzc effects on the acute increase in brain cytokine and chemokine levels were measured as well as the effect on neuronal injury and neurobehavioral function. Results Administration of Mzc (5 mg/kg at 3 h and 9 h post-TBI attenuates the acute increase in proinflammatory cytokine and chemokine levels, reduces astrocyte activation, and the longer term neurologic injury, and neurobehavioral deficits measured by Y maze performance over a 28-day recovery period. Mzc-treated animals also have no significant increase in brain water content (edema, a major cause of the

    Complications involving the central and peripheral nervous system are frequently encountered in critically ill patients. All components of the neuraxis can be involved including the brain, spinal cord, peripheral nerves, neuromuscular junction, and muscles. Neurologic complications adversely impact outcome and length of stay. These complications can be related to underlying critical illness, pre-existing comorbid conditions, and commonly used and life-saving procedures and medications. Familiarity with the myriad neurologic complications that occur in the intensive care unit can facilitate their timely recognition and treatment. Additionally, awareness of treatment-related neurologic complications may inform decision-making, mitigate risk, and improve outcomes. PMID:27098953

    Full Text Available Acute organophosphate (OP poisoning is one of the most common poisonings in emergency medicine and toxicological practice in some of the less-developed nations in South Asia. Traditionally, OP poisoning comes under the domain of emergency physicians, internists, intensivists, and toxicologists. However, some of the complications following OP poisoning are neurological and involve neurologists. The pathophysiological basis for the clinical manifestations of OP poisoning is inactivation of the enzyme, acetylcholinesterase at the peripheral nicotinic and muscarinic and central nervous system (CNS nerve terminals and junctions. Nicotinic manifestations occur in severe cases and late in the course; these comprise of fasciculations and neuromuscular paralysis. There is a good correlation between the electrophysiological abnormalities and the severity of the clinical manifestations. Neurophysiological abnormalities characteristic of nicotinic junctions (mainly neuromuscular junction dysfunction include: (1 single, supramaximal electrical-stimulus-induced repetitive response/s, (2 decrement-increment response to high frequency (30 Hz repetitive nerve stimulation (RNS, and (3 decremental response to high frequency (30 Hz RNS. Atropine ameliorates muscarinic manifestations. Therapeutic agents that can ameliorate nicotinic manifestations, mainly neuromuscular, are oximes. However, the evidence for this effect is inconclusive. This may be due to the fact that there are several factors that determine the therapeutic effect of oximes. These factors include: The OP compound responsible for poisoning, duration of poisoning, severity of poisoning, and route of exposure. There is also a need to study the effect of oximes on the neurophysiological abnormalities.

    2012-01-01

    Mechanical Embolus Removal in Cerebral Ischemia (MERCI) has been supported by medical trials as an improved method of treating ischemic stroke past the safe window of time for administering clot-busting drugs, and was released for medical use in 2004. The importance of analyzing real-world data collected from MERCI clinical trials is key to providing insights on the effectiveness of MERCI. Most of the existing data analysis on MERCI results has thus far employed conventional statistical analysis techniques. To the best of our knowledge, advanced data analytics and data mining techniques have not yet been systematically applied. To address the issue in this thesis, we conduct a comprehensive study on employing state of the art machine learning algorithms to generate prediction criteria for the outcome of MERCI patients. Specifically, we investigate the issue of how to choose the most significant attributes of a data set with limited instance examples. We propose a few search algorithms to identify the significant attributes, followed by a thorough performance analysis for each algorithm. Finally, we apply our proposed approach to the real-world, de-identified patient data provided by Erlanger Southeast Regional Stroke Center, Chattanooga, TN. Our experimental results have demonstrated that our proposed approach performs well. PMID:23366978

    Provinciali, Leandro; Tarquini, Daniela; De Falco, Fabrizio A; Carlini, Giulia; Zappia, Mario; Toni, Danilo

    2015-07-01

    Palliative care in neurology is characterized by the need of taking into account some distinguishing features which supplement and often differ from the general palliative approach to cancer or to severe organ failures. Such position is emphasized by a new concept of palliative assistance which is not limited to the "end of life" stage, as it was the traditional one, but is applied along the entire course of progressive, life-limiting, and disabling conditions. There are various reasons accounting for a differentiation of palliative care in neurology and for the development of specific expertise; the long duration of the advanced stages of many neurological diseases and the distinguishing features of some clinical problems (cognitive disorders, psychic disorders, etc.), in addition to the deterioration of some general aspects (nutrition, etc.), make the general criteria adopted for cancer, severe respiratory, hepatic or renal failures and heart failure inadequate. The neurological diseases which could benefit from the development of a specific palliative approach are dementia, cerebrovascular diseases, movement disorders, neuromuscular diseases, severe traumatic brain injury, brain cancers and multiple sclerosis, as well as less frequent conditions. The growing literature on palliative care in neurology provides evidence of the neurological community's increasing interest in taking care of the advanced and terminal stages of nervous system diseases, thus encouraging research, training and updating in such direction. This document aims to underline the specific neurological requirements concerning the palliative assistance. PMID:26228722

    Our aim was to evaluate Wikipedia page visits in relation to the most common neurological disorders by determining which factors are related to peaks in Wikipedia searches for these conditions. Millions of people worldwide use the internet daily as a source of health information. Wikipedia is a popular free online encyclopedia used by patients and physicians to search for health-related information. The following Wikipedia articles were considered: Alzheimer's disease; Amyotrophic lateral sclerosis; Dementia; Epilepsy; Epileptic seizure; Migraine; Multiple sclerosis; Parkinson's disease; Stroke; Traumatic brain injury. We analyzed information regarding the total article views for 90 days and the rank of these articles among all those available in Wikipedia. We determined the highest search volume peaks to identify possible relation with online news headlines. No relation between incidence or prevalence of neurological disorders and the search volume for the related articles was found. Seven out of 10 neurological conditions showed relations in search volume peaks and news headlines. Six out of these seven peaks were related to news about famous people suffering from neurological disorders, especially those from showbusiness. Identification of discrepancies between disease burden and health seeking behavior on Wikipedia is useful in the planning of public health campaigns. Celebrities who publicly announce their neurological diagnosis might effectively promote awareness programs, increase public knowledge and reduce stigma related to diagnoses of neurological disorders.

    Acute multifocal placoid pigment epitheliopathy (AMPPE) is an autoimmune chorioretinal disease that can be complicated by neurological involvement. There is limited information on this potentially treatable condition in the neurological literature. The objective of this patient series is to describe the neurological complications of AMPPE. We retrospectively identified patients with neurological complications of AMPPE seen at Auckland Hospital between 2008 and 2013 and summarised cases in the literature between 1976 and 2013. We identified five patients with neurological complications of AMPPE at Auckland Hospital and 47 reported patients. These patients demonstrated a spectrum of neurological involvement including isolated headache, stroke or transient ischaemic attack, seizures, venous sinus thrombosis, optic neuritis, sensorineural hearing loss and peripheral vestibular disorder. We propose criteria to define AMPPE with neurological complications. A cerebrospinal fluid (CSF) lymphocytosis in a patient with isolated headache may predict the development of cerebrovascular complications of AMPPE. Patients with cerebrovascular complications of AMPPE have a poor prognosis with high rates of death and neurological disability among survivors. Predictors of poor outcome in those who develop neurological complications of AMPPE are a relapsing course, generalised seizures and multifocal infarction on MRI. All patients with neurological complications of AMPPE, including headache alone, should be investigated with an MRI brain and CSF examination. Patients with focal neurological symptoms should receive intravenous (IV) methylprednisolone followed by a tapering course of oral steroids for at least 3months. Patients with AMPPE and an isolated headache with a CSF pleocytosis should be treated with oral steroids. PMID:27183958

    Full Text Available Abstract Background Apathy is frequently observed in numerous neurological disorders, including Alzheimer's and Parkinson's, as well as neuropsychiatric disorders including schizophrenia. Apathy is defined as a lack of motivation characterized by diminished goal-oriented behavior and self-initiated activity. This study evaluated a chronic restraint stress (CRS protocol in modeling apathetic behavior, and determined whether administration of an anticholinesterase had utility in attenuating CRS-induced phenotypes. Methods We assessed behavior as well as regional neuronal activity patterns using FosB immunohistochemistry after exposure to CRS for 6 h/d for a minimum of 21 d. Based on our FosB findings and recent clinical trials, we administered an anticholinesterase to evaluate attenuation of CRS-induced phenotypes. Results CRS resulted in behaviors that reflect motivational loss and diminished emotional responsiveness. CRS-exposed mice showed differences in FosB accumulation, including changes in the cholinergic basal forebrain system. Facilitating cholinergic signaling ameliorated CRS-induced deficits in initiation and motivational drive and rescued immediate early gene activation in the medial septum and nucleus accumbens. Conclusions Some CRS protocols may be useful for studying deficits in motivation and apathetic behavior. Amelioration of CRS-induced behaviors with an anticholinesterase supports a role for the cholinergic system in remediation of deficits in motivational drive.

    Neurological disorders comprise a variety of complex diseases in the central nervous system, which can be roughly classified as neurodegenerative diseases and psychiatric disorders. The basic and translational research of neurological disorders has been hindered by the difficulty in accessing the pathological center (i.e., the brain) in live patients. The rapid advancement of sequencing and array technologies has made it possible to investigate the disease mechanism and biomarkers from a systems perspective. In this review, recent progresses in the discovery of novel risk genes, treatment targets and peripheral biomarkers employing genomic technologies will be dis-cussed. Our major focus will be on two of the most heavily investigated neurological disorders, namely Alzheimer’s disease and autism spectrum disorder.

    Although humans have long valued creativity, the generation of such innovation is still incompletely understood. Looking at the healthy brain, researchers have localized certain parts for a basic understanding of these mechanisms. By researching the brain affected by neurological disease, scientists have observed unique manifestations of creativity, such as in frontotemporal lobar degeneration, Alzheimer's disease, Parkinson's disease and parkinsonian spectrum disorders, and stroke, which help clarify these creative underpinnings. Incorporating both healthy and disease models of cerebral functioning, neurological and neuroscientific research from recent years has built on established theories and expanded current knowledge.

    Lim, Ming; Gorman, Mark

    2016-01-01

    Autoimmune neurologic diseases are of major clinical importance in children. Antibody-mediated diseases of the central nervous system are now increasingly recognized in childhood, where the antibodies bind to cell surface epitopes on neuronal or glial proteins, and the patients demonstrate either focal or more generalized clinical signs depending on the extent of brain regions targeted by the antibodies. The antibodies are directed towards ion channels, receptors, and membrane proteins; and the diseases include limbic encephalitis and N-methyl-d-aspartate receptor-antibody encephalitis, among many others. Additionally there are conditions where the wider immune system is implicated. Neurologic features like seizures, movement disorders, autonomic dysfunction, and sleep disorders, with neuroimaging and electrophysiologic features, may indicate a specific antibody-mediated or immune disorder. Often, phenotypic overlap is observed between these conditions, and phenotypic variation seen in children with the same condition. Nevertheless, many patients benefit from immunotherapy with substantial improvement, although huge efforts are still required to optimize the outcome for many patients. In many patients no antibodies have yet been identified, even though they respond to immunotherapies. Here we describe the known antibodies and associated diseases, discuss conditions that are thought to be immune-mediated but have no known immunologic biomarker, and provide guidelines for the investigation and classification of these disorders.

    2016-11-01

    A variety of evidence from laboratory and animal studies suggests that lithium has neurotrophic and cytoprotective properties, and may ameliorate or prevent some disease states. We investigated whether such a protective effect can be observed in human psychiatric patients receiving lithium therapy. We carried out a retrospective chart review of 1028 adult psychiatric male and female outpatients attending four lithium clinics in metropolitan New York City. Patients were divided into two groups based on lithium usage, and the prevalence of neurological and cardiovascular disorders was compared. The main outcome measures were the occurrence in the two patient groups of a variety of neurological disorders and myocardial infarction. Odds ratios were calculated to assess the risk of having a disorder for patients receiving lithium compared to patients not receiving lithium: for seizures, the odds ratio was 0.097; for amyotrophic lateral sclerosis, the odds ratio was 0.112; for dementia not otherwise specified, the odds ratio was 0.112; and for myocardial infarction, the odds ratio was 0.30. Logistical regression analysis showed that lithium treatment is a significant negative predictive factor in the prevalence of each of these disease states, when age, duration of clinic attendance, and use of anti-psychotic medications are taken into account. Our results show that patients receiving regular lithium treatment have a reduced prevalence of some neurological disorders and myocardial infarctions. One possible explanation of these results is that a protective effect of lithium observed in laboratory and animal studies may also be present in human patients receiving regular lithium therapy.

    When searching for clues to reach a diagnosis, neurologists often empathise with the detective who is trying to solve a case. The premise of this article is that detective stories have been part of the fabric of neurology ever since the time that it evolved into a discrete medical speciality. We will examine how this form of narrative has found expression in detective mystery fiction and popular science publications created by 20th century neurologist physician-writers. We will also investigate the power of the neurologist's alter ego, Sherlock Holmes: his relationship to founders of clinical neuroscience such as Jean-Martin Charcot, William Gowers and Sigmund Freud, and his influences on neurological practice and its literary traditions.

    Full Text Available Although proverb tests are commonly used in the mental status examination surprisingly little is known about either normal comprehension or the interpretation of proverbial expressions. Current proverbs tests have conceptual and linguistic shortcomings, and few studies have been done to investigate the specific effects of neurological and psychiatric disorders on the interpretation of proverbs. Although frontal lobes have traditionally been impugned in patients who are “concrete”, recent studies targeting deficient comprehension of non literal language (e.g. proverbs, idioms, speech formulas, and indirect requests point to an important role of the right hemisphere (RH. Research describing responses of psychiatrically and neurologically classified groups to tests of proverb and idiom usage is needed to clarify details of aberrant processing of nonliteral meanings. Meanwhile, the proverb test, drawing on diverse cognitive skills, is a nonspecific but sensitive probe of mental status.

    Full Text Available Neurological disorders with a prolonged course, either remediable or otherwise are being seen increasingly in clinical practice and many such patients are young and are part of some organization or other wherein their services are needed if they were healthy and fit. The neurologists who are on the panel of these organizations are asked to certify whether these subjects are fit to work or how long they should be given leave. These certificates may be produced in the court of law and may be subjected to verification by another neurologist or a medical board. At present there are no standard guidelines in our country to effect such certification unlike in orthopedic specialty or in ophthalmology. The following is a beginning, based on which the neurologist can certify the neurological disability of such subjects and convey the same meaning to all neurologists across the country.

    2016-02-01

    Neurological disorders caused by pregnancy and puerperium include the posterior reversible encephalopathy syndrome, the amniotic fluid embolism syndrome (AFES), the postpartum angiopathy due to reversible vasoconstriction syndrome, and the Sheehan syndrome. Hypertension and proteinuria are the hallmarks of preeclampsia, seizures define eclampsia. Hemolysis, elevated liver enzymes and low platelets constitute the HELLP syndrome. Vision disturbances including cortical blindness occur in the posterior reversible encephalopathy syndrome (PRES). The Sheehan syndrome presents with panhypopituitarism post partum due to apoplexia of the pituitary gland in severe peripartal blood loss leading to longstanding hypotension. Some neurological disorders occur during pregnancy and puerperium with an increased frequency. These include stroke, sinus thrombosis, the restless legs syndrome and peripheral nerve syndromes, especially the carpal tunnel syndrome. Chronic neurologic diseases need an interdisciplinary approach during pregnancy. Some anticonvulsants double the risk of birth defects. The highest risk exists for valproic acid, the lowest for lamotrigine and levetiracetam. For MS interval treatment, glatiramer acetate and interferones seem to be safe during pregnancy. All other drugs should be avoided. PMID:26953551

    Travel is associated with a number of neurological disorders that can be divided into two categories: (1) Neurological infections including encephalitides, neurotuberculosis, neurobrucellosis, cysticercosis and trichinosis. Some of these disorders can be prevented by vaccinations, such as Japanese B encephalitis and rabies, some by the use of insect repellents and some by avoiding raw milk products and undercooked meat. (2) Non-infective neurological disorders, such as acute mountain sickness and high altitude cerebral oedema, problems occurring during air travel such as syncope, seizures, strokes, nerve compression, barotrauma and vertigo, motion sickness and foodborne neurotoxic disorders such as ciguatera, shellfish poisoning and intoxication by cassava. This group of diseases and disorders could be prevented if the traveller knows about them, applies simple physiological rules, takes some specific medications and knows how to avoid intoxications in certain geographical areas. Meningococcal meningitis, malaria and jet lag syndrome are extensively discussed in other articles of this issue. The discussion in this paper will be limited to the other disorders. PMID:12615385

  10. Forgiveness: a neurological model.

    Science.gov (United States)

    Clark, Alvin J

    2005-01-01

    A definition of "forgiveness" is chosen that emphasizes its biological and neurological components, namely the cessation of emotions connected with memories of a hurtful act. An experience of forgiveness is analyzed into seven steps and each is associated with a neurological source. The cornerstone hypothesis is that, before forgiveness takes place, memories periodically arouse fear stemming from the amygdala. This fear drives a pattern of anger and fight-or-flight readiness. Under appropriate circumstances the frontal cortex interrupts the pattern and quells the fear response in the amygdala. The resultant relaxation of muscular tension signals the cortex that forgiveness has occurred. In addition, the memory pathway from the rhinal cortex and hippocampus to the amygdala is inhibited. Finally, a tangible act confirms that the memories no longer stimulate the amygdala and the pattern of anger and stress do not recur. The relationship of the neurological model with other theoretical models is presented and some avenues for experimental testing of the model are mentioned. PMID:16002228

    Functional disorders are defined as neurological symptoms without causative organic pathology identified. They are a diverse and often neglected group of disorders. The aim of this was to determine the incidence and outcome of functional neurological disorders in an Australian neurology practice. Over a 17month period, all patients presenting to a single outpatient neurology service were evaluated to determine the incidence and outcome of these disorders. A total of 884 patients were assessed and of these, 137 had a final diagnosis of functional neurological illness, equating to an incidence of 15% of all patients seen. Functional disorders were the third most common presentation overall. Patients with functional disorders were younger, more likely to be female and had a higher rate of current psychiatric comorbidity compared to other neurology patients. Sensory symptoms were the most common manifestation (48%) followed by limb weakness (37%) and psychogenic non-epileptic seizures (14%). Outcome information was available for 49% of patients at an average of 3months follow-up. 45% had some improvement in their symptoms, 43% had static symptoms and 12% had worsening of symptoms. This study confirms the high incidence of functional disorders in outpatient neurology practice. Early improvement was seen in a substantial proportion of patients and is influenced by duration of symptoms. PMID:26754851

    Full Text Available Pyroptosis is a new process of programmed cell death, which has been discovered and confirmed in recent years. Its cardinal features include activation of caspase-1 and a massive release of inflammatory cytokines (interleukin (IL-1β, IL-18, etc. The morphological characteristics, occurrence and regulatory mechanisms of the pyroptosis greatly, differ from other cell death mechanisms such as apoptosis and necrosis. It has already been proven that pyroptosis participates and plays an important role in a wide range of neuronal diseases. Here, we review the current understanding of the pyroptosis and its roles in neurological diseases.

    Constituents of the Cannabis plant, cannabinoids, may be of therapeutic value in neurologic diseases. The most abundant cannabinoids are Δ(9)-tetrahydrocannabinol, which possesses psychoactive properties, and cannabidiol, which has no intrinsic psychoactive effects, but exhibits neuroprotective properties in preclinical studies. A small number of high-quality clinical trials support the safety and efficacy of cannabinoids for treatment of spasticity of multiple sclerosis, pain refractory to opioids, glaucoma, nausea and vomiting. Lower level clinical evidence indicates that cannabinoids may be useful for dystonia, tics, tremors, epilepsy, migraine and weight loss. Data are also limited in regards to adverse events and safety. Common nonspecific adverse events are similar to those of other CNS 'depressants' and include weakness, mood changes and dizziness. Cannabinoids can have cardiovascular adverse events and, when smoked chronically, may affect pulmonary function. Fatalities are rare even with recreational use. There is a concern about psychological dependence, but physical dependence is less well documented. Cannabis preparations may presently offer an option for compassionate use in severe neurologic diseases, but at this point, only when standard-of-care therapy is ineffective. As more high-quality clinical data are gathered, the therapeutic application of cannabinoids will likely expand. PMID:25427150

    We report on the unusual behavior of coprophagia (eating one's own feces) in neurologic disorders. The Mayo Clinic Health Sciences-computerized clinical database was queried for all patients evaluated at our institution between 1995 and 2015 in which coprophagia was documented in the medical records. Twenty-six patients were identified of which 17 had coprophagia. Of the 17 patients, five were excluded due to age at onset less than 10 years, leaving 12 adult patients for this study. The median age at onset of coprophagia in the 12 patients was 55 years (range 20-88 years), and half were female. Additional behaviors were common including scatolia (fecal smearing), hypersexuality, aggression, and pica (eating objects of any kind). Coprophagia was associated with neurodegenerative dementia in six patients, developmental delay in two, and one each with seizures, steroid psychosis, frontal lobe tumor, and schizoaffective disorder. Brain imaging in the six patients with dementia showed moderate-to-severe medial temporal lobe atrophy, as well as mild frontal lobe atrophy. Autopsy examination was performed in one patient and revealed frontotemporal lobar degeneration pathology. Many different behavioral and pharmacologic therapies were implemented, yet only haloperidol was associated with discontinuation of the behavior. Coprophagia is associated with different neurologic disorders, particularly neurodegenerative dementias. The behavior may be related to medial temporal lobe atrophy, similar to the Klüver-Bucy syndrome. Haloperidol appears to be effective in treating the behavior, at least in some patients.

    Patients with prolonged or rapidly recurring convulsions lasting more than 5 min are in status epilepticus (SE) and require immediate resuscitation. Although there are relatively few randomized clinical trials, available evidence and experience suggest that early and aggressive treatment of SE improves patient outcomes, for which reason this was chosen as an Emergency Neurological Life Support protocol. The current approach to the emergency treatment of SE emphasizes rapid initiation of adequate doses of first-line therapy, as well as accelerated second-line anticonvulsant drugs and induced coma when these fail, coupled with admission to a unit capable of neurological critical care and electroencephalography monitoring. This protocol will focus on the initial treatment of SE but also review subsequent steps in the protocol once the patient is hospitalized. PMID:26438462

The capacity to diagnose common neurologic conditions and rare disorders is lacking. The burden of neurologic disease on the continent is not known, and this lack of knowledge limits the ability to lobby for better health care provision. Inability to practice in resource-limited settings has led to the migration of skilled professionals away from Africa. Referral systems from primary to tertiary are often unpredictable and chaotic. There is a lack of access to reliable supplies of basic neurology treatments such as antiepileptic drugs. Few countries have nationally accepted guidelines either for the management of epilepsy or status epilepticus. There is a great need to develop better training capacity across Africa in the recognition and management of neurologic conditions in children, from primary health care to the subspecialist level.

    Massey, E Wayne; Moon, Richard E

    2014-01-01

    Diving exposes a person to the combined effects of increased ambient pressure and immersion. The reduction in pressure when surfacing can precipitate decompression sickness (DCS), caused by bubble formation within tissues due to inert gas supersaturation. Arterial gas embolism (AGE) can also occur due to pulmonary barotrauma as a result of breath holding during ascent or gas trapping due to disease, causing lung hyperexpansion, rupture and direct entry of alveolar gas into the blood. Bubble disease due to either DCS or AGE is collectively known as decompression illness. Tissue and intravascular bubbles can induce a cascade of events resulting in CNS injury. Manifestations of decompression illness can vary in severity, from mild (paresthesias, joint pains, fatigue) to severe (vertigo, hearing loss, paraplegia, quadriplegia). Particularly as these conditions are uncommon, early recognition is essential to provide appropriate management, consisting of first aid oxygen, targeted fluid resuscitation and hyperbaric oxygen, which is the definitive treatment. Less common neurologic conditions that do not require hyperbaric oxygen include rupture of a labyrinthine window due to inadequate equalization of middle ear pressure during descent, which can precipitate vertigo and hearing loss. Sinus and middle ear overpressurization during ascent can compress the trigeminal and facial nerves respectively, causing temporary facial hypesthesia and lower motor neuron facial weakness. Some conditions preclude safe diving, such as seizure disorders, since a convulsion underwater is likely to be fatal. Preventive measures to reduce neurologic complications of diving include exclusion of individuals with specific medical conditions and safe diving procedures, particularly related to descent and ascent.

    Cerebral cortical activity is constant throughout the entire human life, but substantially changes during the different phases of the sleep-wake cycle (wakefulness, non-REM sleep and REM sleep), as well as in relation to available information. In particular, perception of the environment is closely linked to the wake-state, while during sleep perception turns to the internal domain or endogenous cerebral activity. External and internal information are mutually exclusive. During wakefulness a neuronal mechanism allows attention to focus on the environment whereas endogenous cortical activity is ignored. The opposite process is provided during sleep. The function external attention-internal attention is coupled with the two modes of brain function during wakefulness and during sleep, providing two possible cortical status: thinking and dreaming. Several neurological processes may influence the declaration of the three states of being or may modify their orderly oscillation through the sleep-wake cycle. In addition, endogenous information and its perception (dreams) may be modified. Disturbances of dreaming may configurate in different general clinical scenarios: lack of dreaming, excess of dreaming (epic dreaming), paroxysmal dreaming (epileptic), nightmares, violent dreaming, daytime-dreaming (hallucinations), and lucid dreaming. Sensorial deprivation, as well as the emergence of internal perception may be the underlying mechanism of hallucinations. The probable isomorphism between hallucinations and dreaming is postulated, analyzed and discussed. PMID:11143502

To the best of our knowledge, there are very few studies published from India till date. Selected and confirmed fourteen cases of neurological mitochondrial cytopathies with different clinical syndromes admitted between 1997 and 2000 are being reported. There were 8 male and 6 female patients. The mean age was 24.42+/-11.18 years (range 4-40 years. Twelve patients could be categorized into well-defined syndromes, while two belonged to undefined group. In the defined syndrome categories, three patients had MELAS (mitochondrial encephalopathy, lactic acidosis and stroke like episodes, three had MERRF (myoclonic epilepsy and ragged red fibre myopathy, three cases had KSS (Kearns-Sayre Syndrome and three were diagnosed to be suffering from mitochondrial myopathy. In the uncategorized group, one case presented with paroxysmal kinesogenic dystonia and the other manifested with generalized chorea alone. Serum lactic acid level was significantly increased in all the patients (fasting 28.96+/-4.59 mg%, post exercise 41.02+/-4.93 mg%. Muscle biopsy was done in all cases. Succinic dehydrogenase staining of muscle tissue showed subsarcolemmal accumulation of mitochondria in 12 cases. Mitochondrial DNA study could be performed in one case only and it did not reveal any mutation at nucleotides 3243 and 8344.

    2015-01-01

    Hypophosphatasia (HPP) is a bone metabolic disorder caused by mutations in the liver/bone/kidney alkaline phosphatase gene (ALPL), which encodes tissue-nonspecific alkaline phosphatase (TNAP). This disease is characterized by disrupted bone and tooth mineralization, and reduced serum AP activity. Along with bone and tooth symptoms, many neurological symptoms, seizure, encephalopathy, intracranial hypertension, mental retardation, deafness, and growth hormone deficiency (GHD), are frequently found in HPP patients. Seizure occurs in severe HPP types soon after birth, and responds to pyridoxine, but is an indicator of lethal prognosis. Encephalopathy rarely presents in severe HPP types, but has severe sequelae. Intracranial hypertension complicated in mild HPP types develops after the age of 1 year and sometimes need neurosurgical intervention. Mental retardation, deafness and GHD are more frequently found in Japanese HPP patients. Mental retardation occurs in all HPP types. Deafness in perinatal lethal type is both conductive and sensorineural. GHD develops in all but perinatal lethal type and the diagnosis tends to delay. The pathogenesis of these neural features of HPP might be due to impairment of both vitamin B6 metabolism and central nervous system development by ALPL mutations. PMID:26219717

    Neurologic itch is defined as pruritus resulting from any dysfunction of the nervous system. Itch arising due to a neuroanatomic pathology is seen to be neuropathic. Causes of neuropathic itch range from localized entrapment of a peripheral nerve to generalized degeneration of small nerve fibers. Antipruritic medications commonly used for other types of itch such as antihistamines and corticosteroids lack efficacy in neuropathic itch. Currently there are no therapeutic options that offer relief in all types of neuropathic pruritus, and treatment strategies vary according to etiology. It is best to decide on the appropriate tests and procedures in collaboration with a neurologist during the initial work-up. Treatment of neuropathic itch includes general antipruritic measures, local or systemic pharmacotherapy, various physical modalities, and surgery. Surgical intervention is the obvious choice of therapy in cases of spinal or cerebral mass, abscess, or hemorrhagic stroke, and may provide decompression in entrapment neuropathies. Symptomatic treatment is needed in the vast majority of patients. General antipruritic measures should be encouraged. Local treatment agents with at least some antipruritic effect include capsaicin, local anesthetics, doxepin, tacrolimus, and botulinum toxin A. Current systemic therapy relies on anticonvulsants such as gabapentin and pregabalin. Phototherapy, transcutaneous electrical nerve stimulation, and physical therapy have also been of value in selected cases. Among the avenues to be explored are transcranial magnetic stimulation of the brain, new topical cannabinoid receptor agonists, various modes of acupuncture, a holistic approach with healing touch, and cell transplantation to the spinal cord.

  17. Neurological manifestations of malaria

    Full Text Available The involvement of the nervous system in malaria is reviewed in this paper. Cerebral malaria, the acute encephalopathy which complicates exclusively the infection by Plasmodium falciparum commonly affects children and adolescents in hyperendemic areas. Plugging of cerebral capillaries and venules by clumped, parasitized red cells causing sludging in the capillary circulation is one hypothesis to explain its pathogenesis. The other is a humoral hypothesis which proposes nonspecific, immune-mediated, inflammatory responses with release of vasoactive substances capable of producing endothelial damage and alterations of permeability. Cerebral malaria has a mortality rate up to 50%, and also a considerable longterm morbidity, particularly in children. Hypoglycemia, largely in patients treated with quinine, may complicate the cerebral symptomatology. Other central nervous manifestations of malaria include intracranial hemorrhage, cerebral arterial occlusion, and transient extrapyramidal and neuropsychiiatric manifestations. A self-limiting, isolated cerebellar ataxia, presumably caused by immunological mechanisms, in patients recovering from falciparum malaria has been recognized in Sri Lanka. Malaria is a common cause of febrile seizures in the tropics, and it also contributes to the development of epilepsy in later life. Several reports of spinal cord and peripheral nerve involvement are also available. A transient muscle paralysis resembling periodic paralysis during febrile episodes of malaria has been described in some patients. The pathogenesis of these neurological manifestations remains unexplored, but offers excellent perspectives for research at a clinical as well as experimental level.

    Full Text Available This clinical review about the neurological examination in small animals describes the basics about the first steps of investigation when dealing with neurological patients. The knowledge of how to perform the neurological examination is important however more important is how to correctly interpret these performed tests. A step-by-step approach is mandatory and examiners should master the order and the style of performing these tests. Neurological conditions can be sometimes very distressing for owners and for pets that might not be the most cooperating. The role of a veterinary surgeon, as a professional, is therefore to collect the most relevant history, to examine a patient in a professional manner and to give to owners an educated opinion about the further treatment and prognosis. However neurological examinations might look challenging for many. But it is only the clinical application of neuroanatomy and neurophysiology to an every-day situation for practicing veterinarians and it does not require any specific in-to-depth knowledge. This clinical review is aimed not only to provide the information on how to perform the neurological examination but it is also aimed to appeal on veterinarians to challenge their daily routine and to start practicing on neurologically normal patients. This is the best and only way to differentiate between the normal and abnormal in a real situation.

    , the targets identified had little or no established link to the diseases considered. In others, molecular targets of CBD were entirely consistent with those already actively exploited in relevant, clinically used, neurological treatments. Finally, CBD was found to act upon a number of targets that are linked to neurological therapeutics but that its actions were not consistent withmodulation of such targets that would derive a therapeutically beneficial outcome. Overall, we find that while >65 discrete molecular targets have been reported in the literature for CBD, a relatively limited number represent plausible targets for the drug's action in neurological disorders when judged by the criteria we set. We conclude that CBD is very unlikely to exert effects in neurological diseases through modulation of the endocannabinoid system. Moreover, a number of other molecular targets of CBD reported in the literature are unlikely to be of relevance owing to effects only being observed at supraphysiological concentrations. Of interest and after excluding unlikely and implausible targets, the remaining molecular targets of CBD with plausible evidence for involvement in therapeutic effects in neurological disorders (e.g., voltage-dependent anion channel 1, G protein-coupled receptor 55, CaV3.x, etc.) are associated with either the regulation of, or responses to changes in, intracellular calcium levels. While no causal proof yet exists for CBD's effects at these targets, they represent the most probable for such investigations and should be prioritized in further studies of CBD's therapeutic mechanism of action.

    The remote effects of malignant tumors in most cases of paraneoplastic neurological syndromes(PNS)are mediated by autoimmune processes against antigens shared by the tumor cells and the nervous tissue(onconeural antigens). Onconeural (or paraneoplastic)antibodies are broadly categorized into two groups according to the location of the corresponding onconeural antigens, inside or on the surface of neurons. Antibodies established as clinically relevant diagnostic markers for PNS are designated as well-characterized onconeural antibodies (or classical antibodies)that target intracellular antigens(Hu, Yo, Ri, CV2/CRMP5,Ma2, and amphiphysin). They also serve as useful markers in detecting primary tumors. Recent identification of new antibodies as markers of subtypes of limbic encephalitis has also expanded the concept of autoimmune limbic encephalitis. These autoantibodies are directed to neuronal cell-surface antigens including neurotransmitter receptors(NMDA, AMPA, and GABAB receptors)and ion channels(VGKC). They are less frequently associated with cancer, so that they cannot be used as specific markers for PNS. Autoimmune limbic encephalitis with anti-neuronal cell surface antobodies and paraneoplastic limbic encephalitis with classical antibodies overlap in some clinical features but are pathophysiologically distinct. Classical antibodies are not simple tumor markers. They seem to be closely related to the disease mechanisms because specific intrathecal synthesis has been shown in PNS patients. However, attempts to produce an animal model of PNS by passive transfer of these antibodies have been unsuccessful, and there is no direct evidence demonstrating the pathogenic role of classical antibodies. Instead, some circumstantial evidence, including pathological studies showing extensive infiltrates of T cells in the CNS of the patients, supports the hypothesis that cytotoxic-T cell mechanisms cause irreversible neuronal damage. On the other hand, humoral immune

    Full Text Available Objective: To chronicle the history of medicine and neurology in India with a focus on its establishment and evolution. Background: The history of neurology in India is divided into two periods: ancient and modern. The ancient period dates back to the mid-second millennium Before Christ (B.C. during the creation of the Ayurvedic Indian system of Medicine, which detailed descriptions of neurological disorders called Vata Vyadhi. The early 20 th century witnessed the birth of modern Indian medicine with the onset of formal physician training at the nation′s first allopathic medical colleges located in Madras (1835, Calcutta (1835 and Mumbai (1848. Prior to India′s independence from Britain in 1947, only 25 medical schools existed in the entire country. Today, there are over 355. In 1951, physicians across the field of neurology and neurosurgery united to create the Neurological Society of India (NSI. Four decades later in 1991, neurologists branched out to establish a separate organization called the Indian Academy of Neurology (IAN. Design/Methods: Information was gathered through literature review using PubMed, MD Consult, OVID, primary texts and research at various academic institutions in India. Results: Neurological disorders were first described in ancient India under Ayurveda. The transition to modern medicine occurred more recently through formal training at medical schools beginning in the 1930′s. Early pioneers and founders of the NSI (1951 include Dr. Jacob Chandy, Dr. B Ramamurthi, Dr. S. T. Narasimhan and Dr. Baldev Singh. Later, Dr. J. S. Chopra, a prominent neurologist and visionary, recognized the need for primary centers of collaboration and subsequently established the IAN (1991. The future of Neurology in India is growing rapidly. Currently, there are 1100 practicing neurologists and more than 150 post-graduate trainees who join the ranks every year. As the number of neurologists rises across India, there is an increase in

    We describe the neurologic findings in a patient with alpha-N-acetylgalactosaminidase deficiency (Kanzaki disease). Clinical and electrophysiologic studies revealed sensory-motor polyneuropathy, and sural nerve pathology showed decreased density of myelinated fibers with axonal degeneration. The patient had mildly impaired intellectual function with abnormal brain MRI and sensory-neuronal hearing impairment with repeated episodes of vertigo attacks. These findings suggest that Kanzaki disease may develop neurologic complications in the CNS and peripheral nervous system. PMID:15136691

    Hippocrates is one of the most influential medical doctors of all times. He started observing and experimenting in times of mysticism and magic. He carried a holistic and humanitarian approach to the patient with examination as the principal approach-inspection, palpation and auscultation are still the most important tools in diagnosing algorithms of today. He had immense experience with the human body most likely due to numerous wound treatments he had performed; some even believe he performed autopsies despite the negative trend at the time. Hippocrates identified the brain as the analyst of the outside world, the interpreter of consciousness and the center of intelligence and willpower. Interestingly, Hippocrates was aware of many valid concepts in neurology; his treatise On the Sacred Disease was the most important for understanding neurology and epilepsy. His other ideas pioneered modern day neurology mentioning neurological diseases like apoplexy, spondylitis, hemiplegia, and paraplegia. Today, 10 % of neurological Pubmed and 7 % of neuroscience Scopus reviews mention Corpus Hippocraticum as one of the sources. Therefore, Hippocrates may be considered as the forefather of neurology.

    Full Text Available BACKGROUND AND AIMS: Snake bite is an important cause of mortality and morbidity in certain parts of Sri Lanka. This study was designed to determine the offending snakes, neurological manifestations, disease course, and outcome in neurotoxic envenomation. METHODS AND MATERIAL: Fifty six consecutive patients admitted with neurological manifestations following snake bite were studied prospectively. Data were obtained regarding the offending snakes, neurological symptoms, time taken for onset of symptoms, neurological signs, and time taken for recovery. RESULTS: The offending snake was Russell′s viper in 27(48.2%, common and Sri Lankan krait in 19(33.9%, cobra in 3(5.4%, and unidentified in 7(12.5%. Ptosis was the commonest neurological manifestation seen in 48(85.7% followed by ophthalmoplegia (75%, limb weakness (26.8%, respiratory failure (17.9%, palatal weakness (10.7%, neck muscle weakness (7.1%, and delayed sensory neuropathy (1.8%. Neurological symptoms were experienced usually within 6 hours after the bite. Following administration of antivenom, the signs of recovery became evident within a few hours to several days. The duration for complete recovery ranged from four hours to two weeks. CONCLUSIONS: Complete recovery of neuromuscular weakness was observed in all patients except for one who died with intracerebral haemorrhage shortly after admission.

    There is a quite good definition of medical care for patients suffering from chronicle neurological diseases. However the neurologist role in taking care of urgent cases is substantially less determined. This paper is analyzing one year efforts of the on duty neurological team in the Out Patient Department and Emergency Division of the Neurology Department in Sarajevo. During this period the on duty neurological team examined the total of 3939 patients, out of which 1022 patients where kept for treatment. The patients where most frequently assigned to the Emergency unit for following reasons: vascular incident of the Central Nervous System(1955 patients or 50%), cerebrovascular accident represented with 1290 or 33%, and TIA of the carotid and vertebrobasilar area 544 or 14% along with hypertensive encephalopathia, 118 or 3%. This is followed by the group of the short-term disturbance of consciousness (472 or 125), out of which the consciousness crises represented 257 or 7%, and epileptic crises 215 or 5%. Following are the lower percentages of the headaches (287 or 7%), radicular painful syndrome of cervical and lumbal area (209 or 5%), vertigo (183 or 5%), neurophatia (167 or 4%), etc. The more extensive number of patients admitted at the Emergency Division where suffering from brain stroke (800 or 78%), TIA was represented by a lower number (172 or 17%). Only 50 patients had other diagnosis. The ischemic stroke represented 674 or 81% with patients suffering from the brain stroke and the hemorrhagic stroke 153 or 19%. Today, the urgent neurological conditions represent a particular area of Neurology, not only neurologists need to know but also other medical doctors, to enable the patients to be forwarded on time to the appropriate care institution.

    The purpose of this article was to provide a literature review of occupational neurological disorders and related research in Korea, focusing on chemical hazards. We reviewed occupational neurological disorders investigated by the Occupational Safety and Health Research Institute of Korean Occupational Safety and Health Agency between 1992 and 2009, categorizing them as neurological disorders of the central nervous system (CNS), of the peripheral nervous system (PNS) or as neurodegenerative disorders. We also examined peer-reviewed journal articles related to neurotoxicology, published from 1984 to 2009. Outbreaks of occupational neurological disorder of the CNS due to inorganic mercury and carbon disulfide poisoning had helped prompt the development of the occupational safety and health system of Korea. Other major neurological disorders of the CNS included methyl bromide intoxication and chronic toxic encephalopathy. Most of the PNS disorders were n-hexane-induced peripheral neuritis, reported from the electronics industry. Reports of manganese-induced Parkinsonism resulted in the introduction of neuroimaging techniques to occupational medicine. Since the late 1990s, the direction of research has been moving toward degenerative disorder and early effect of neurotoxicity. To understand the early effects of neurotoxic chemicals in the preclinical stage, more follow-up studies of a longer duration are necessary. PMID:21258587

    The diver's nervous system is extremely sensitive to high ambient pressure, which is the sum of atmospheric and hydrostatic pressure. Neurological complications associated with diving are a difficult diagnostic and therapeutic challenge. They occur in both commercial and recreational diving and are connected with increasing interest in the sport of diving. Hence it is very important to know the possible complications associated with this kind of sport. Complications of the nervous system may result from decompression sickness, pulmonary barotrauma associated with cerebral arterial air embolism (AGE), otic and sinus barotrauma, high pressure neurological syndrome (HPNS) and undesirable effect of gases used for breathing. The purpose of this review is to discuss the range of neurological symptoms that can occur during diving accidents and also the role of patent foramen ovale (PFO) and internal carotid artery (ICA) dissection in pathogenesis of stroke in divers.

    Full Text Available Endemic skeletal fluorosis is widely prevalent in India and is a major public health problem. The first ever report of endemic skeletal fluorosis and neurological manifestation was from Prakasam district in Andhra Pradesh in the year 1937. Epidemiological and experimental studies in the endemic areas suggest the role of temperate climate, hard physical labor, nutritional status, presence of abnormal concentrations of trace elements like strontium, uranium, silica in water supplies, high fluoride levels in foods and presence of kidney disease in the development of skeletal fluorosis. Neurological complications of endemic skeletal fluorosis, namely radiculopathy, myelopathy or both are mechanical in nature and till date the evidence for direct neurotoxicity of fluoride is lacking. Prevention of the disease should be the aim, knowing the pathogenesis of fluorosis. Surgery has a limited role in alleviating the neurological disability and should be tailored to the individual based on the imaging findings.

    2012-01-01

    Full Text Available Paraneoplastic neurological syndromes (PNS are rare disorders associated with cancer, not caused by direct invasion, metastasis or consequences of treatment. They are usually autoimmune in nature. Often, PNS precedes the manifestations of cancer. Onconeural antibodies are important in the diagnosis and management of these disorders. These antibodies are specific for the malignancy rather than for a particular neurological syndrome. Often, there are different antibodies associated with the same syndrome. Multiple antibodies are also known to coexist in a given patient with malignancy. While investigating a patient for suspected PNS, the entire gamut of onconeural antibodies should be investigated so as not to miss the diagnosis. In 30-40% of the cases, PNS can occur without antibodies. Investigations for identifying the underlying cancer can be directed by the antibody panel. If conventional screening for cancer is negative, a positron emission scanning/computed tomography scan can be useful. Patients need follow-up surveillance for cancer if not detected in the first instance. Cancer detection and treatment, immunotherapy and supportive care are important components of treatment of PNS. Immunotherapy is very effective in PNS associated with cell membrane-associated antibodies like voltage-gated potassium channel complex, NMDA receptor antibodies and voltage-gated calcium channel antibodies. Immunotherapy includes steroids, IVIgG, plasmaphereis, cytotoxic medications and rituximab. Supportive therapy includes symptomatic treatment with antiepileptic and analgesic medications, physiotherapy, speech therapy and occupational therapy. PNS can mimic any neurologic syndrome. A high index of clinical suspicion is important for early diagnosis and prompt management and better outcome.

    Marcel Proust is one of the most important French writers of the 20th century. His relationship with medicine and with neurology is possibly linked to the fact that his asthma was considered to be a psychosomatic disease classified as neurasthenia. Stendhal's syndrome is a rare psychiatric syndrome characterized by anxiety and affective and thought disturbances when a person is exposed to a work of art. Here, the authors describe neurological aspects of Proust's work, particularly the occurrence of Stendhal's syndrome and syncope when he as well as one of the characters of In Search of Lost Time see Vermeer's View of Delft during a visit to a museum.

    Iorio, Justin A; Reid, Patrick; Kim, Han Jo

    2016-09-01

    The number of surgeries performed for adult spinal deformity (ASD) has been increasing due to an aging population, longer life expectancy, and studies supporting an improvement in health-related quality of life scores after operative intervention. However, medical and surgical complication rates remain high, and neurological complications such as spinal cord injury and motor deficits can be especially debilitating to patients. Several independent factors potentially influence the likelihood of neurological complications including surgical approach (anterior, lateral, or posterior), use of osteotomies, thoracic hyperkyphosis, spinal region, patient characteristics, and revision surgery status. The majority of ASD surgeries are performed by a posterior approach to the thoracic and/or lumbar spine, but anterior and lateral approaches are commonly performed and are associated with unique neural complications such as femoral nerve palsy and lumbar plexus injuries. Spinal morphology, such as that of hyperkyphosis, has been reported to be a risk factor for complications in addition to three-column osteotomies, which are often utilized to correct large deformities. Additionally, revision surgeries are common in ASD and these patients are at an increased risk of procedure-related complications and nervous system injury. Patient selection, surgical technique, and use of intraoperative neuromonitoring may reduce the incidence of complications and optimize outcomes. PMID:27250041

    International Nuclear Information System (INIS)

    Objective: To investigate the mechanism of neurologic injury after endovascular graft exclusion of abdominal aortic aneurysms and the methods of prevention and treatment. Materials: Since March 1997 to October 2002, endovascular graft exclusion for abdominal aortic aneurysm have been preformed on 136 patients, with one occurrence of neurologic injury after the operation. The main body-short limb graft was used in this case (Talent) and the operation was successful. The patient complained of bilateral lower extremities pain and disability. Electromusculogram showed bilateral femoral nerve injury. Then the patient was treated with vitamin B12, hyperbaric oxygen and physical therapy for 2 months outcoming with the symptom improvement. Conclusions: Neurologic injury after endovascular graft exclusion for abdominal aortic aneurysms is possible due to the occlusion of the lumbar artery during the operation. Early treatment is important and more effective. Later nerve nutrition and physical treatment can improve some symptoms partly

    We report 3 cases of patients with testicular cancer and stage II seminoma who developed neurological symptoms with bilateral leg weakness about 4 to 9 months after radiation therapy (RT). They all received RT to the para-aortic lymph nodes with a total dose of 40 Gy (36 Gy + 4 Gy as a boost...... the spinal cord. RT is believed to produce plexus injury by both direct toxic effects and secondary microinfarction of the nerves, but the exact pathophysiology of RT-induced injury is unclear. Since reported studies of radiation-induced neurological adverse effects are limited, it is difficult to...... estimate their frequency and outcome. The treatment of neurological symptoms due to RT is symptomatic....

    2012-01-01

    Regarding the impact of visceral dysfunction on quality of life, bowel and bladder management is a very important problem. The management of the patient with neurological bladder is often a source of uncertainty for both patients and healthcare personnel. Since the need of specialized training is growing, two CME e-learning courses have been developed to provide physicians and nurses competencies for the enhancement of the daily life of the patients. The present study aims at evaluating courses attendance and outcomes. Attendance data confirm the interest for both courses. The results document a pretty good objective and subjective effectiveness of the e-learning courses but low attitude to exploit he support of an asynchronous tutor. The analysis of test results gives some hints for eventual quality improvement of the courses themselves. PMID:22874390

    Objectives To review neurological complications after the influenza A (H1N1) pdm09, highlighting the clinical differences between patients with post-vaccine or viral infection. Design A search on Medline, Ovid, EMBASE, and PubMed databases using the keywords “neurological complications of Influenza AH1N1” or “post-vaccine Influenza AH1N1.” Setting Only papers written in English, Spanish, German, French, Portuguese, and Italian published from March 2009 to December 2012 were included. Sample We included 104 articles presenting a total of 1636 patient cases. In addition, two cases of influenza vaccine-related neurological events from our neurological care center, arising during the period of study, were also included. Main outcome measures Demographic data and clinical diagnosis of neurological complications and outcomes: death, neurological sequelae or recovery after influenza A (H1N1) pdm09 vaccine or infection. Results The retrieved cases were divided into two groups: the post-vaccination group, with 287 patients, and the viral infection group, with 1349 patients. Most patients in the first group were adults. The main neurological complications were Guillain-Barre syndrome (GBS) or polyneuropathy (125), and seizures (23). All patients survived. Pediatric patients were predominant in the viral infection group. In this group, 60 patients (4.7%) died and 52 (30.1%) developed permanent sequelae. A wide spectrum of neurological complications was observed. Conclusions Fatal cases and severe, permanent, neurological sequelae were observed in the infection group only. Clinical outcome was more favorable in the post-vaccination group. In this context, the relevance of an accurate neurological evaluation is demonstrated for all suspicious cases, as well as the need of an appropriate long-term clinical and imaging follow-up of infection and post-vaccination events related to influenza A (H1N1) pdm09, to clearly estimate the magnitude of neurological complications

    A preliminary clinical study by our group demonstrated Bushen Yisui Capsule (formerly cal ed Er-huang Formula) in combination with conventional therapy is an effective prescription for the treat-ment of multiple sclerosis. However, its effect on axonal injury during early multiple sclerosis re-mains unclear. In this study, a MOG 35-55-immunized C57BL/6 mouse model of experimental au-toimmune encephalomyelitis was intragastrical y administered Bushen Yisui Capsule. The results showed that Bushen Yisui Capsule effectively improved clinical symptoms and neurological function of experimental autoimmune encephalomyelitis. In addition, amyloid precursor protein expression was down-regulated and microtubule-associated protein 2 was up-regulated. Experimental findings indicate that the disease-preventive mechanism of Bushen Yisui Capsule in experimental autoim-mune encephalomyelitis was mediated by amelioration of axonal damage and promotion of rege-neration. But the effects of the high-dose Bushen Yisui Capsule group was not better than that of the medium-dose and low-dose Bushen Yisui Capsule group in preventing neurological dysfunction.

    2015-12-01

    Iatrogenic neurologic deficits after lumbar spine surgery are rare complications, but important to recognize and manage. Complications such as radiculopathy, spinal cord compression, motor deficits (i.e. foot drop with L5 radiculopathy), and new onset radiculitis, while uncommon do occur. Attempts at mitigating these complications with the use of neuromonitoring have been successful. Guidance in the literature as to the true rate of iatrogenic neurologic deficit is limited to several case studies and retrospective designed studies describing the management, prevention and treatment of these deficits. The authors review the lumbar spinal surgery literature to examine the incidence of iatrogenic neurologic deficit in the lumbar spinal surgery literature. An advanced MEDLINE search conducted on May 14th, 2015 from January 1, 2004 through May 14, 2015, using the following MeSH search terms "postoperative complications," then subterms "lumbar vertebrae," treatment outcome," "spinal fusion," and "radiculopathy" were included together with "postoperative complications" in a single search. Postoperative complications including radiculopathy, weakness, and spinal cord compression were included. The definition of iatrogenic neurologic complication was limited to post-operative radiculopathy, motor weakness or new onset pain/radiculitis. An advanced MEDLINE search conducted on May 14th, 2015 using all of the above terms together yielded 21 results. After careful evaluation, 11 manuscripts were excluded and 10 were carefully reviewed. The most common indications for surgery were degenerative spondylolisthesis, spondylosis, scoliosis, and lumbar stenosis. In 2783 patients in 12 total studies, there were 56 patients who had reported a postoperative neurologic deficit for a rate of 5.7. The rates of deficits ranged from 0.46% to 17% in the studies used. The average rate of reported neurologic complications within these papers was 9% (range 0.46-24%). Thirty patients of a total of

    Science.gov (United States)

    Rittenberger, Jon C; Friess, Stuart; Polderman, Kees H

    2015-12-01

    Cardiac arrest is the most common cause of death in North America. Neurocritical care interventions, including targeted temperature management (TTM), have significantly improved neurological outcomes in patients successfully resuscitated from cardiac arrest. Therefore, resuscitation following cardiac arrest was chosen as an emergency neurological life support protocol. Patients remaining comatose following resuscitation from cardiac arrest should be considered for TTM. This protocol will review induction, maintenance, and re-warming phases of TTM, along with management of TTM side effects. Aggressive shivering suppression is necessary with this treatment to ensure the maintenance of a target temperature. Ancillary testing, including electrocardiography, computed tomography and/or magnetic resonance imaging of the brain, continuous electroencephalography monitoring, and correction of electrolyte, blood gas, and hematocrit changes, are also necessary to optimize outcomes.

  2. Nuclear medical investigations in neurology

    International Nuclear Information System (INIS)

    The methods of nuclear medicine in neurology aim to establish the extent and location of cranial circulation disturbances, determine specific types of intra-cranial tumors, demonstrate liquor fistulae and establish the existence of cerebrospinal fluid circulation disorders or non-resorptive hydrocephalus. The term 'cerebral scintiscanning' nowadays is used to denote serieal cerebral scintiscanning with technetium-99-labelled radiopharmaceuticals (DTPA, glucoheptonate). This non-invasive procedure is divided in three phases: radionuclide angiography, early-status and late-status gamma-camera imaging. The investigation is little stressing, the technical expenditure is relatively small (to assess the cerebral circulation a mini-computer is required), the radiation exposure for the gonads is 70 mrad/10 mCi (0.7 mGy/440 MBq). Nuclear examination methods in neurology can today only be made use of in connection with other, proven procedures in neurodiagnostics. These are x-ray computerized tomography, Doppler sonography and (invasive) cranialangiography. (orig./MG)

Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

  18. Neurological causes of taste disorders.

    Science.gov (United States)

    Heckmann, J G; Lang, C J G

    2006-01-01

    In caring for patients with taste disorders, the clinical assessment should include complete examination of the cranial nerves and, in particular, gustatory testing. Neurophysiological methods such as blink reflex and masseter reflex allow the testing of trigeminofacial and trigeminotrigeminal pathways. Modern imaging methods (MRI and computed tomography) enable the delineation of the neuroanatomical structures which are involved in taste and their relation to the bony skull base. From a neurological point of view, gustatory disorders can result from damage at any location of the neural gustatory pathway from the taste buds via the peripheral (facial, glossopharyngeal and vagal nerve) and central nervous system (brainstem, thalamus) to its representation within the cerebral cortex. Etiopathogenetically, a large number of causes has to be considered, e.g. drugs and physical agents, cerebrovascular disorders including dissection of the carotid artery and pontine/thalamic lesions, space-occupying processes - in particular tumors compressing the cerebellopontine angle and the jugular foramen of the skull base - head trauma and skull base fractures, isolated cranial mononeuropathy (e.g. Bell's palsy) or polyneuropathy, epilepsy, dementia, multiple sclerosis and major depression. In addition to this, aging can also lead to diminished taste perception. Due to the broad differential diagnostic considerations, it is essential to look for additional, even mild, neurological signs and symptoms. Treatment must relate to the underlying cause. Zinc may be tried in idiopathic dysgeusia. PMID:16733343

    Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

    With few exceptions, neurology was nonexistent in the United States until the Civil War years. From 1861 to 1865, the United States saw a bitter armed conflict between the North (the Union) and the South (the Confederate States or Confederacy), and during those years, neurology was born in the United States. In 1861, Silas Weir Mitchell, together with George Morehouse and William Keen, opened and operated the first neurological hospital in Philadelphia, with the backing of the Surgeon General William Hammond. They treated and studied many peripheral nerve diseases, which led to their making the medical world aware of several conditions, including causalgia (now known as complex regional pain syndrome) and the phantom limb phenomenon. Progress in neurology, both at that time and in subsequent years, owed a great deal to cross-fertilization from Europe. Charles Edouard Brown-Séquard exemplified this. He held multiple medical positions on both sides of the Atlantic, including a position at Harvard in 1864. His teachings, to some extent, contributed to the development of neurology in the United States. In the Confederate states, medical care was less well organized, and neurology only developed later. After the war, in 1874, Mitchell, Hammond, and a few others founded the American Neurological Association. While war influenced the development of medicine, and neurology in particular, medicine also helped to shape the outcome of the war. PMID:27035676

    Genetic loss of collagen VII causes recessive dystrophic epidermolysis bullosa (RDEB)-a severe skin fragility disorder associated with lifelong blistering and disabling progressive soft tissue fibrosis. Causative therapies for this complex disorder face major hurdles, and clinical implementation remains elusive. Here, we report an alternative evidence-based approach to ameliorate fibrosis and relieve symptoms in RDEB. Based on the findings that TGF-β activity is elevated in injured RDEB skin, we targeted TGF-β activity with losartan in a preclinical setting. Long-term treatment of RDEB mice efficiently reduced TGF-β signaling in chronically injured forepaws and halted fibrosis and subsequent fusion of the digits. In addition, proteomics analysis of losartan- vs. vehicle-treated RDEB skin uncovered changes in multiple proteins related to tissue inflammation. In line with this, losartan reduced inflammation and diminished TNF-α and IL-6 expression in injured forepaws. Collectively, the data argue that RDEB fibrosis is a consequence of a cascade encompassing tissue damage, TGF-β-mediated inflammation, and matrix remodeling. Inhibition of TGF-β activity limits these unwanted outcomes and thereby substantially ameliorates long-term symptoms. PMID:26194911

    In Germany dedicated neurological-neurosurgical critical care (NCC) is the fastest growing specialty and one of the five big disciplines integrated within the German critical care society (Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin; DIVI). High-quality investigations based on resilient evidence have underlined the need for technical advances, timely optimization of therapeutic procedures, and multidisciplinary team-work to treat those critically ill patients. This evolution has repeatedly raised questions, whether NCC-units should be run independently or better be incorporated within multidisciplinary critical care units, whether treatment variations exist that impact clinical outcome, and whether nowadays NCC-units can operate cost-efficiently? Stroke is the most frequent disease entity treated on NCC-units, one of the most common causes of death in Germany leading to a great socio-economic burden due to long-term disabled patients. The main aim of NCC employs surveillance of structural and functional integrity of the central nervous system as well as the avoidance of secondary brain damage. However, clinical evaluation of these severely injured commonly sedated and mechanically ventilated patients is challenging and highlights the importance of neuromonitoring to detect secondary damaging mechanisms. This multimodal strategy not only requires medical expertise but also enforces the need for specialized teams consisting of qualified nurses, technical assistants and medical therapists. The present article reviews most recent data and tries to answer the aforementioned questions. PMID:27206707

    Full Text Available Hashimoto%u2019s encephalopathy (HE is a rare disorder associated with autoimmune thyroiditis. Etiology of HE is not completely understood. High levels of serum antithyroid antibodies are seen in HE. Presentation with otoimmune thyroiditis, cognitive impairment, psychiatric and neurologic symptoms and absence of bacterial or viral enfections are characteristics of HE. HE is a steroid responsive encephalopathy. 60 years old male patient admitted to hospital with forget fulness continuing for 9 months and speech loss starting 2 days ago. Strong positivity of antithyroid antibodies increases the odds for HE. Thyroid function tests showed severe hypothyroidism. Electroencephalography and magnetic resonance imaging results were compatible with HE. HE is diagnosed with differantial diagnosis and exclusion of other reasons. This uncommon disorder is not recognised enough. High titres of serum antithyroid antiboides are always needed for diagnosis. Correct diagnosis requires awareness of wide range of cognitive and clinical presentations of HE.

    Traumatic brain injury (TBI) is increasingly appreciated to be highly prevalent and deleterious to neurological function. At present, no effective treatment options are available, and little is known about the complex cellular response to TBI during its acute phase. To gain insights into TBI pathogenesis, we developed a novel murine closed-skull brain injury model that mirrors some pathological features associated with mild TBI in humans and used long-term intravital microscopy to study the dynamics of the injury response from its inception. Here we demonstrate that acute brain injury induces vascular damage, meningeal cell death, and the generation of reactive oxygen species (ROS) that ultimately breach the glial limitans and promote spread of the injury into the parenchyma. In response, the brain elicits a neuroprotective, purinergic-receptor-dependent inflammatory response characterized by meningeal neutrophil swarming and microglial reconstitution of the damaged glial limitans. We also show that the skull bone is permeable to small-molecular-weight compounds, and use this delivery route to modulate inflammation and therapeutically ameliorate brain injury through transcranial administration of the ROS scavenger, glutathione. Our results shed light on the acute cellular response to TBI and provide a means to locally deliver therapeutic compounds to the site of injury.

    Until such time as results of more rigorous studies are available, the morbidity rates for thyroid dysfunction cited here must suffice. The 1955 to 1956 outpatient "incidence" for England and Wales was 1.1 per 1,000 for thyrotoxicosis and 1.7 per 1,000 for myxedema (18). United States in-patient "incidence" for 1971 was 0.16 per 1,000 for thyrotoxicosis and 0.13 per 1,000 for myxedema (25). The 1935 to 1967 average annual incidence of Graves' disease for females in Olmsted County, Minnesota, was 30.5 per 100,000 (10). Well over 50% of hyperthyroid patients have clinical evidence of mild or moderate muscle weakness. Usually this weakness is proximal, and electro-myography and muscle biopsy confirm the existence of myopathic process (Table 11). Severe muscular weakness of acute onset is relatively rare and is encountered in approximately 1% of hyperthyroid patients (11,17,40). Ophthalmoplegia and psychosis are reported 4% and 2% of patients, respectively (17). Myasthenia gravis, although well publicized, is estimated to occur in less than 1% of patients (3,30). TPP is virtually nonexistent in the West; in the Orient it is reported in 2 to 8% of hyperthyroid patients and is 20 to 60 times more frequent in the hyperthyroid male than in the hyperthyroid female (Table 12). The neurologic symptomatology of myxedema is more extensive, and agreement among the various series is poor. The only unselected series addressing itself to neuromuscular manifestations of myxedema that is suitable for citation is that of Scarpalezos et al. (36). This comprehensive study was done without apparent patient selection, and it reported 2% of patients with definite carpal tunnel syndrome, 6% with myopathy, and 18% with polyneuropathy (Table 13). Reported percentages of hypothyroid patients found to have neurologic manifestations of cerebellar dysfunction are extremely diverse: ataxic gait was reported in 5 to 32% (6,7,12,27) of patients and dysdiadochokinesia in 6 to 52% (7,12,27).

    Full Text Available Advances in telecommunication which started with telephone lines, FAX, integrated service digital network (ISDN lines and now internet have provided an unprecedented opportunity for transfer of knowledge and sharing of information. The information can be used for overlapping applications in patient care, teaching and research. In medicine there is increasing utilization of telemedicine; radiology and pathology being regarded as mature specialties and emergency medicine as maturing specialties compared to other evolving specialties which include psychiatry, dermatology, cardiology and ophthalmology. Of the emergencies, status epilepticus and stroke have high potential for improving patient management. Administration of tPA was more frequent when carried out under telemedicine guidance. Telemedicine has great potential for medical education. The principles of education are in congruence with those of telemedicine and can be closely integrated in the existing medical education system. Our experience of telemedicine as a medical education tool is based on video conferencing with SCB Medical College, Cuttack. We had 30 sessions during 2001 to 2004 in which 2-3 cases were discussed in each session. The patients′ details, radiological and neurophysiological findings could be successfully transmitted. These conferences improved the knowledge of participants, provided an opportunity for a second opinion as well as modified the treatment decisions in some cases. The advances in telemedicine should be utilized more extensively in neurology, especially in emergency management, epilepsy and stroke patients as well, as it may have a role in neurophysiology and movement disorders.

    Extracorporeal membrane oxygenation (ECMO) is a life-saving mechanical respiratory and/or circulatory support for potentially reversible severe heart or respiratory injury untreatable with conventional therapies. Thanks to the technical and management improvements the use of ECMO has increased dramatically in the last few years. Data in the literature show a progressive increase in the overall outcome. Considering the improving survival rate of patients on ECMO, and the catastrophic effect of neurological injuries in such patients, the topic of neurological damage during the ICU stay in ECMO is gaining importance. We present a case series of six neurological injuries that occurred in 1 year during the ECMO run or after the ECMO weaning. In each case the neurological complication had a dramatic effect: ranging from brain death to prolonged ICU stay and long term disability. This case series has an informative impact for the multidisciplinary teams treating ECMO patients because of its heterogeneity in pathogenesis and clinical manifestation: cerebral hemorrhage, ischemic stroke due to cerebral fat embolism, acute disseminated encephalomyelitis due to H1N1 Influenza. In our ECMO hub we started strict neurological monitoring involving intensivists, a neurologist and our radiology service, but neurological complications are still an insidious diagnosis and treatment. Considering several possible neurological injuries may help reduce delay in diagnosis and speed rehabilitation. PMID:26895322

    Full Text Available Context: The rehabilitation needs of the patients in neurological Intensive Care Units (ICUs vary from that of a medical ICU patient. Early mobilization is known to improve the various neurological outcomes in patients admitted to neurological ICUs, although little is known about the practice pattern among physiotherapists. The mobilization practice pattern may vary significantly than that of developed countries due to the reasons of differences in training of professionals, availability of equipment, and financial assistance by health insurance. Aim of the Study: To study the current mobilization practices by the physiotherapists in neurological ICUs of India. Subjects and Methods: A cross-sectional survey was conducted with a content validated questionnaire about the mobilization practices. Online questionnaire was distributed to physiotherapists working in neurological ICUs of India. Descriptive statistics were used. Results: Out of 185 e-mails sent, 82 physiotherapists completed the survey (survey response rate = 44%. Eighty participants (97.6% mentioned that the patients received some form of mobilization during the day. The majority of the physiotherapists (58.5%, “always” provided bed mobility exercises to their patients when it was found appropriate for the patients. Many physiotherapists (41.5% used tilt table “sometimes” to introduce orthostatism for their patients. Conclusion: Mobilization in various forms is being practiced in the neurological ICUs of India. However, fewer mobilization sessions are conducted on weekends and night hours in Indian Neurological ICUs.

They all received RT to the para-aortic lymph nodes with a total dose of 40 Gy (36 Gy + 4 Gy as a boost against the tumour bed with a conventional fractionation of2 Gy/day, 5 days per week. RT was applied as hockey-stick portals, also called L-fields. In 2 cases, the symptoms fully resolved. Therapeutic irradiation can cause significant injury to the peripheral nerves of the lumbosacral plexus and/or to the spinal cord. RT is believed to produce plexus injury by both direct toxic effects and secondary microinfarction of the nerves, but the exact pathophysiology of RT-induced injury is unclear. Since reported studies of radiation-induced neurological adverse effects are limited, it is difficult to estimate their frequency and outcome. The treatment of neurological symptoms due to RT is symptomatic.

    2010-04-01

    Music making (playing an instrument or singing) is a multimodal activity that involves the integration of auditory and sensorimotor processes. The ability to sing in humans is evident from infancy, and does not depend on formal vocal training but can be enhanced by training. Given the behavioral similarities between singing and speaking, as well as the shared and distinct neural correlates of both, researchers have begun to examine whether singing can be used to treat some of the speech-motor abnormalities associated with various neurological conditions. This paper reviews recent evidence on the therapeutic effects of singing, and how it can potentially ameliorate some of the speech deficits associated with conditions such as stuttering, Parkinson's disease, acquired brain lesions, and autism. By reviewing the status quo, it is hoped that future research can help to disentangle the relative contribution of factors to why singing works. This may ultimately lead to the development of specialized or "gold-standard" treatments for these disorders, and to an improvement in the quality of life for patients. PMID:21152359

    Full Text Available Objective: The objective of the present study was to assess the impact of neurological consultation and intervention upon patient outcome in intensive care unit (ICU. Settings: A retrospective observational study was conducted in the 24-bedded multispecialty ICU of a 350 bedded tertiary care hospital over 8 months period, from January 2011 to August 2011. Critically, ill-patients with varied neurological symptomatology affecting the course of illness and ICU discharge were included. Neurological consult sought for, investigations ordered by the neurologist, interventions carried out, treatment started and the impact of such treatment on the outcome of patients were noted. The length of ICU stay was also noted. Results: Over a period of 8 months, there were 864 ICU admissions. On neurological consult, 23 patients had a positive finding affecting the outcome: 5 patients were diagnosed to have parkinson′s disease, 4 patients had neuromuscular disease, 9 patients had high creatinine phosphokinase levels, 2 patients had restless legs syndrome and 3 patients were diagnosed to have seizure disorder. Conclusions: On being examined and investigated by neurologist, a variety of co-existing neurological disorders could be diagnosed and if managed early, patients had a faster recovery, rapid weaning and early discharge from the ICU.

    Background Although the burden of neurological disorders is highest among populations in developing countries there is a dearth of data on the clinical spectrum of these disorders. Objective To profile the frequency of neurologic disorders and basic demographic data in an adult neurology out-patient service commissioned in 2011 in Kumasi, Ghana. Methods The study was conducted at the neurology clinic of the Komfo Anokye Teaching Hospital in Kumasi, Ghana. Over a three year period, all medical records of patients enrolled at the out-patient neurology clinic was reviewed by a neurologist and neurological diagnoses classified according to ICD-10. Results 1812 adults enrolled for care in the neurology out-patient service between 2011 and 2013. This comprised of 882 males and 930 females (male: female ratio of 1.0: 1.1) with an overall median age of 54 (IQR, 39–69) years. The commonest primary neurological disorders seen were strokes, epilepsy and seizure disorders, and movement disorders at frequencies of 57.1%, 19.8%, and 8.2% respectively. Conclusions Cerebrovascular diseases, epilepsy and movement disorders were among the commonest neurological disorders and the major contributors to neurologic morbidity among Ghanaians in an urban neurology clinic.

  7. Music therapy in neurological rehabilitation settings

    Full Text Available The neurologic music therapy is a new scope of music therapy. Its techniques deal with dysfunctions resulting from diseases of the human nervous system. Music can be used as an alternative modality to access functions unavailable through non-musical stimulus. Processes in the brain activated by the influence of music can be generalized and transferred to non-musical functions. Therefore, in clinical practice, the translation of non-musical therapeutic exercises into analogous, isomorphic musical exercises is performed. They make use of the executive peculiarity of musical instruments and musical structures to prime, cue and coordinate movements. Among musical components, a repetitive rhythm plays a significant role. It regulates physiologic and behavioural functions through the mechanism of entrainment (synchronization of biological rhythms with musical rhythm based on acoustic resonance. It is especially relevant for patients with a deficient internal timing system in the brain. Additionally, regular rhythmic patterns facilitate memory encoding and decoding of non-musical information hence music is an efficient mnemonic tool. The music as a hierarchical, compound language of time, with its unique ability to access affective/motivational systems in the brain, provides time structures enhancing perception processes, mainly in the range of cognition, language and motor learning. It allows for emotional expression and improvement of the motivation for rehabilitation activities. The new technologies of rhythmic sensory stimulation (i.e. Binaural Beat Stimulation or rhythmic music in combination with rhythmic light therapy appear. This multimodal forms of stimulation are used in the treatment of stroke, brain injury, dementia and other cognitive deficits. Clinical outcome studies provide evidence of the significant superiority of rehabilitation with music over the one without music.

    The neurologic music therapy is a new scope of music therapy. Its techniques deal with dysfunctions resulting from diseases of the human nervous system. Music can be used as an alternative modality to access functions unavailable through non-musical stimulus. Processes in the brain activated by the influence of music can be generalized and transferred to non-musical functions. Therefore, in clinical practice, the translation of non-musical therapeutic exercises into analogous, isomorphic musical exercises is performed. They make use of the executive peculiarity of musical instruments and musical structures to prime, cue and coordinate movements. Among musical components, a repetitive rhythm plays a significant role. It regulates physiologic and behavioural functions through the mechanism of entrainment (synchronization of biological rhythms with musical rhythm based on acoustic resonance). It is especially relevant for patients with a deficient internal timing system in the brain. Additionally, regular rhythmic patterns facilitate memory encoding and decoding of non-musical information hence music is an efficient mnemonic tool. The music as a hierarchical, compound language of time, with its unique ability to access affective/motivational systems in the brain, provides time structures enhancing perception processes, mainly in the range of cognition, language and motor learning.

    Mood disorder and depressive syndromes represent a common comorbid condition in neurological disorders with a prevalence rate that ranges between 20% and 50% of patients with stroke, epilepsy, multiple sclerosis, and Parkinson's disease. Notwithstanding, these conditions are often under-diagnosed and under-treated in the clinical practice and negatively affect the functional recovery, the adherence to treatment, the quality of life, and even the mortality risk. In addition, a bidirectional association between depression and neurological disorders may be possible being that depressive syndromes may be considered as a risk factor for certain neurological diseases. Despite the large amount of evidence regarding the effects of music therapy (MT) and other musical interventions on different aspects of neurological disorders, no updated article reviewing outcomes such as mood, emotions, depression, activity of daily living and so on is actually available; for this reason, little is known about the effectiveness of music and MT on these important outcomes in neurological patients. The aim of this article is to provide a narrative review of the current literature on musical interventions and their effects on mood and depression in patients with neurological disorders. Searching on PubMed and PsycInfo databases, 25 studies corresponding to the inclusion criteria have been selected; 11 of them assess the effects of music or MT in Dementia, 9 explore the efficacy on patients with Stroke, and 5 regard other neurological diseases like Multiple Sclerosis, Amyotrophic Lateral Sclerosis/motor neuron disease, Chronic quadriplegia, Parkinson's Disease, and Acquired Brain dysfunctions. Selected studies are based on relational and rehabilitative music therapy approaches or concern music listening interventions. Most of the studies support the efficacy of MT and other musical interventions on mood, depressive syndromes, and quality of life on neurological patients. PMID:25815256

    Full Text Available Congenital, traumatic, or extrinsic causes can lead people to paraplegia; some of these are potentially; reversible and others are not. Paraplegia can couse hip flexion contracture and, consequently, pressure sores, scoliosis, and hyperlordosis; lumbar and groin pain are strictly correlated. Scientific literature contains many studies about children hip flexion related to neurological diseases, mainly caused by cerebral palsy; only few papers focus on this complication in adults. In this study we report our experience on surgical treatment of adult hip flexion contracture due to neurological diseases; we have tried to outline an algorithm to choose the best treatment avoiding useless or too aggressive therapies. We present 5 cases of adult hips flexion due to neurological conditions treated following our algorithm. At 1-year-follow-up all patients had a good clinical outcome in terms of hip range of motion, pain and recovery of walking if possible. In conclusion we think that this algorithm could be a good guideline to treat these complex cases even if we need to treat more patients to confirm this theory. We believe also that postoperation physiotherapy it is useful in hip motility preservation, improvement of muscular function, and walking ability recovery when possible.

    International Nuclear Information System (INIS)

    Molecular imaging in neurology and neuroscience is a suspenseful and fast developing tool in order to quantitatively image genomics and proteomics by means of direct and indirect markers. Because of its high-sensitive tracer principle, nuclear medicine imaging has the pioneering task for the methodical progression of molecular imaging. The current development of molecular imaging in neurology changes from the use of indirect markers of gene and protein expression to the direct imaging of the molecular mechanisms. It is the aim of this article to give a short review on the status quo of molecular imaging in neurology with emphasis on clinically relevant aspects. (orig.)

    Full Text Available OBJECTIVE: to test the clinical utility of an early amplitude-integrated electroencephalography (aEEG to predict short-term neurological outcome in term newborns at risk of neurology injury. METHODS: this was a prospective, descriptive study. The inclusion criteria were neonatal encephalopathy, neurologic disturbances, and severe respiratory distress syndrome. Sensitivity, specificity, positive and negative predictive values, and likelihood ratio (LR were calculated. Clinical and demographic data were analyzed. Neurological outcome was defined as the sum of clinical, electroimaging, and neuroimaging findings. RESULTS: ten of the 21 monitored infants (48% presented altered short-term neurologic outcome. The aEEG had 90% sensitivity, 82% specificity, 82% positive predictive value, and 90% negative predictive value. The positive LR was 4.95, and the negative LR was 0.12. In three of 12 (25% encephalopathic infants, the aEEG allowed for a better definition of the severity of their condition. Seizures were detected in eight infants (38%, all subclinical at baseline, and none had a normal aEEG background pattern. The status of three infants (43% evolved and required two or more drugs for treatment. CONCLUSIONS: in infants with encephalopathy or other severe illness, aEEG disturbances occur frequently. aEEG provided a better classification of the severity of encephalopathy, detected early subclinical seizures, and allowed for monitoring of the response to treatment. aEEG was a useful tool at the neonatal intensive care unit for predicting poor short-term neurological outcomes for all sick newborn.

    Full Text Available Background : Despite the increasing use of recombinant tissue plasminogen activator (rt-PA in acute ischemic stroke, uncertainty persists about the short- and long-term outcome of the thrombolysed patients. Objective : To identify predictors of major neurological improvement at 24 h after intravenous rt-PA administration in patients of acute ischemic stroke and their relationship with outcome at 12 months. Materials and Methods : We analyzed the data of the patients with acute ischemic stroke treated as per the National Institute of Neurological Disorders and Stroke (NINDS criteria with intravenous rt-PA between January 2000 and June 2009 at a tertiary care center in south India. Major neurological improvement was defined by an 8-point improvement in National Institute of Health Stroke Scale (NIHSS score or an NIHSS score of 0 or 1 at 24 h. Good outcome was defined as a 12-month modified Rankin Scale (mRS of 0 to 1. Results : Of the 72 patients with acute ischemic stroke treated with intravenous rt-PA, 23 (32% patients had major neurological improvement at 24 h. Age <60 years (OR 1.9, 95% CI 1.7 to3.2, admission glucose levels <8 mmol/L (OR 3.87, 95% CI 1.9 to 9.2 and mild to moderate baseline stroke severity (NIHSS median score 10+ 6 were associated with major neurological improvement after adjusting for co variables. Major neurological improvement at 24 h was an independent predictor of good outcome (mRS=1 at 12 months (OR 13.9, 95% CI 6.84 to 40.2. Conclusions : Age <60 years, glucose levels <8 mmol/L and mild to moderate stroke severity (NIHSS median score 10±6 was associated with major neurological improvement after intravenous rt-PA. Major neurological improvement at 24 h after the administration of intravenous thrombolysis independently predicted good outcome at 12 months.

    Full Text Available Lidocaine has been used for more than 50 years for spinal anesthesia and has a remarkable safety record. In 1993, a new adverse effect, transient neurologic toxicity was described in patients recovering from spinal anesthesia with lidocaine. Transient neurological symptoms have been defined as pain in the lower extremities (buttocks, thighs and legs after an uncomplicated spinal anesthesia and after an initial full recovery during the immediate postoperative period (less than 24 h. The incidence of transient neurological symptoms reported in prospective, randomized trials varies from 4% to 37%. The etiology of transient neurological symptoms remains unkonwn. Despite the transient nature of this syndrome, it has proven to be difficult to treat effectively. Drug or some interventional therapy may be necessary.

    Full Text Available Francisco Javier Carod-Artal1,21Neurology Department, Raigmore hospital, Inverness, UK; 2Universitat Internacional de Catalunya (UIC, Barcelona, Spain Abstract: Dengue is the most common mosquito-borne viral infection worldwide. There is increased evidence for dengue virus neurotropism, and neurological manifestations could make part of the clinical picture of dengue virus infection in at least 0.5%–7.4% of symptomatic cases. Neurological complications have been classified into dengue virus encephalopathy, dengue virus encephalitis, immune-mediated syndromes (acute disseminated encephalomyelitis, myelitis, Guillain–Barré syndrome, neuritis brachialis, acute cerebellitis, and others, neuromuscular complications (hypokalemic paralysis, transient benign muscle dysfunction and myositis, and dengue-associated stroke. Common neuro-ophthalmic complications are maculopathy and retinal vasculopathy. Pathogenic mechanisms include systemic complications and metabolic disturbances resulting in encephalopathy, direct effect of the virus provoking encephalitis, and postinfectious immune mechanisms causing immune-mediated syndromes. Dengue viruses should be considered as a cause of neurological disorders in endemic regions. Standardized case definitions for specific neurological complications are still needed.

    Full Text Available Abstract Background Team-based learning (TBL, a new active learning method, has not been reported for neurology education. We aimed to determine if TBL was more effective than passive learning (PL in improving knowledge outcomes in two key neurology topics - neurological localization and neurological emergencies. Methods We conducted a modified crossover study during a nine-week internal medicine posting involving 49 third-year medical undergraduates, using TBL as the active intervention, compared against self-reading as a PL control, for teaching the two topics. Primary outcome was the mean percentage change in test scores immediately after (post-test 1 and 48 hours after TBL (post-test 2, compared to a baseline pre-test. Student engagement was the secondary outcome. Results Mean percentage change in scores was greater in the TBL versus the PL group in post-test 1 (8.8% vs 4.3%, p = 0.023 and post-test 2 (11.4% vs 3.4%, p = 0.001. After adjustment for gender and second year examination grades, mean percentage change in scores remained greater in the TBL versus the PL group for post-test 1 (10.3% vs 5.8%, mean difference 4.5%,95% CI 0.7 - 8.3%, p = 0.021 and post-test 2 (13.0% vs 4.9%, mean difference 8.1%,95% CI 3.7 - 12.5%, p = 0.001, indicating further score improvement 48 hours post-TBL. Academically weaker students, identified by poorer examination grades, showed a greater increase in scores with TBL versus strong students (p Conclusions Compared to PL, TBL showed greater improvement in knowledge scores, with continued improvement up to 48 hours later. This effect is larger in academically weaker students. TBL is an effective method for improving knowledge in neurological localization and neurological emergencies in undergraduates.

    Full Text Available The European Federation of Neurological Societies (EFNS Scientific Panel on Neurorehabilitation established a Task Force on standards in neurological rehabilitation in June 1996. The remit for the Task Force was to: (1 produce a report on the state of neurological rehabilitation across Europe; and (2 recommend standards for the provision of neurological services for disabled people. The main conclusions of the Task Force were as follows: (1 A questionnaire circulated to each European member country has indicated a significant lack of adequate neurological rehabilitation facilities across Europe. Very few countries have any established network of neurological rehabilitation centres. Few countries have adequately trained neurological rehabilitation physicians, therapists or nurses. Such poor facilities should be seen in the context of the large numbers and increasing prevalence of people with neurological disabilities. (2 The Task Force has summarized the significant benefits that can follow from the establishment of a dedicated and cost effective neurological rehabilitation service including functional improvement, reduction of unnecessary complications, better coordination and use of limited resources, improved opportunities for education, training and research and a clear point of contact for the disabled person. (3 The Task Force recommends minimum standards for the prevention of neurological disability including access to health education, genetic counselling and emergency resources. The Task Force also encourages governments to invest in improved legislation for accident prevention. (4 The Task Force has outlined some minimum standards for the staffing of a neurological rehabilitation service including improved training both for neurologists and rehabilitation physicians. Such training could include a cross-national training programme both for physicians and other health care staff. (5 The Task Force supports a two-tier system of

    2012-02-03

    The objective of the present study was to assess the activity of the Liaison Psychiatry service of Cork University Hospital in relation to all in-patient neurology referrals over a 12-month period. Of 1685 neurology admissions, 106 (6%) were referred to liaison psychiatry for assessment. 91 referrals (86%) met criteria for a psychiatric disorder according to DSM-IV, the commonest being major depression (24%) and somatoform disorder (23%). Patients with multiple sclerosis or epilepsy comprised nearly half of all referrals (48 cases; 45%). Approximately 20% of M.S. in-patients (21 cases) were referred for psychiatric assessment, with the corresponding figure in epilepsy being 25% (18 cases). Although only 106 (6%) neurology in-patients were referred to liaison psychiatry, psychiatric diagnoses were documented in 327 (20%) discharge forms, presumably reflecting previous diagnosis. The above findings indicate that psychiatric illness is common among neurology inpatients screened by liaison psychiatry yet referral rates are relatively low in terms of the overall number of neurology in-patients. Psychiatric disorders were diagnosed in 86% of referrals indicating high concordance between neurologists and liaison psychiatry regarding the presence of a psychiatric disorder.

    2012-11-01

    Full Text Available Dengue infection is a leading cause of illness and death in tropical and subtropical regions of the world. Forty percent of the world’s population currently lives in these areas. The clinical picture resulting from dengue infection can range from relatively minor to catastrophic hemorrhagic fever. Recently, reports have increased of neurological manifestations. Neuropathogenesis seems to be related to direct nervous system viral invasion, autoimmune reaction, metabolic and hemorrhagic disturbance. Neurological manifestations include encephalitis, encephalopathy, meningitis, Guillain-Barré syndrome, myelitis, acute disseminated encephalomyelitis, polyneuropathy, mononeuropathy, and cerebromeningeal hemorrhage. The development of neurological symptoms in patients with positive Immunoglobulin M (IgM dengue serology suggests a means of diagnosing the neurological complications associated with dengue. Viral antigens, specific IgM antibodies, and the intrathecal synthesis of dengue antibodies have been successfully detected in cerebrospinal fluid. However, despite diagnostic advancements, the treatment of neurological dengue is problematic. The launch of a dengue vaccine is expected to be beneficial.

    We reviewed neurologic complications after renal transplantation in children over a 20-year period. Neurologic complications were classified as early (within 3 months) and delayed (beyond 3 months). Of 115 children, 10 (8.7%) had complications. Early complications were found in 4.35% of patients: seizures in 4 (posterior reversible leukoencephalopathy syndrome due to immunosuppressant toxicity, sepsis/presumed meningitis, and indeterminate) and headaches in 1. One patient with seizures received levetiracetam for 6 months and 1 with headaches received amitriptyline prophylaxis. Late complications were noted in 4.35% of patients: seizures in 3 (posterior reversible leukoencephalopathy syndrome due to hypertension, hypertensive encephalopathy), headaches in 2, and tremors in 1. Two patients with seizures were treated with anti-epilepsy medications; 1 with migraine received cyproheptadine prophylaxis. Neurologic complications develop in children after renal transplantation. Seizures due to posterior reversible leukoencephalopathy syndrome were the commonest complication. Early detection and appropriate management of these complications is important. PMID:23752071

    We discuss two different ways of measuring outcome in a sample of 20 patients who had intracranial aneurysm surgery. Patients were evaluated at discharge using the Karnofsky Scale and the Glasgow Outcome Scale. Six months after discharge we conducted a neuropsychiatric evaluation including cognitive, behavioral, and mood status assessment. Although 13 of our patients had a "good recovery', 18 had some neuropsychiatric impairment. We did not find statistical relationships between the discharge evaluation and the neuropsychiatric assessment at follow-up. We discuss the need for developing new outcome measures to pick-up neuropsychiatric deficits, beyond the traditional neurologic semiology. PMID:8837062

    Effective combination antiretroviral therapy has transformed HIV infection into a chronic disease, with HIV-infected individuals living longer and reaching older age. Neurological disease remains common in treated HIV, however, due in part to ongoing inflammation and immune activation that persist in chronic infection. In this review, we highlight recent developments in our understanding of several clinically relevant neurologic complications that can occur in HIV infection despite treatment, including HIV-associated neurocognitive disorders, symptomatic CSF escape, cerebrovascular disease, and peripheral neuropathy.

    Neurology case reports have a long history of transmitting important medical information across many generations for the improvement of patient care. Case reports contribute much to the physician's knowledge base from which treatment hypotheses and ideas form. Elements of a modern case report, as presented in the CARE (CAse REport) guidelines, include the abstract, introduction, case presentation, discussion, conclusion, patient's perspective, and consent statement. The sections are described here, as well as the application of CARE guidelines to a published neuromuscular case report. Writing case reports offer an ideal opportunity for neurologists to publish interesting case findings and carry on the tradition of neurologic case reporting. PMID:27048575

    Myocarditis is a clinically severe disease; however, no effective treatment has been established. The aim of this study was to determine whether cacao bean (Theobroma cacao) polyphenols ameliorate autoimmune myocarditis. We used an experimental autoimmune myocarditis (EAM) model in Balb/c mice. Mice with induced EAM were treated with a cacao polyphenol extract (CPE, n=12) or vehicle (n=12). On day 21, hearts were harvested and analyzed. Elevated heart weight to body weight and fibrotic area ratios as well as high cardiac cell infiltration were observed in the vehicle-treated EAM mice. However, these increases were significantly suppressed in the CPE-treated mice. Reverse transcriptase-PCR revealed that mRNA expressions of interleukin (Il)-1β, Il-6, E-selectin, vascular cell adhesion molecule-1 and collagen type 1 were lower in the CPE group compared with the vehicle group. The mRNA expressions of nicotinamide adenine dinucleotide phosphate-oxidase (Nox)2 and Nox4 were increased in the vehicle-treated EAM hearts, although CPE treatment did not significantly suppress the transcription levels. However, compared with vehicle treatment of EAM hearts, CPE treatment significantly suppressed hydrogen peroxide concentrations. Cardiac myeloperoxidase activity, the intensity of dihydroethidium staining and the phosphorylation of nuclear factor-κB p65 were also lower in the CPE group compared with the vehicle group. Our data suggest that CPE ameliorates EAM in mice. CPE is a promising dietary supplement to suppress cardiovascular inflammation and oxidative stress. PMID:26657007

    1999-11-09

    A fuse and filter arrangement is described for limiting and ameliorating electrode shorting in capacitive deionization water purification systems utilizing carbon aerogel, for example. This arrangement limits and ameliorates the effects of conducting particles or debonded carbon aerogel in shorting the electrodes of a system such as a capacitive deionization water purification system. This is important because of the small interelectrode spacing and the finite possibility of debonding or fragmentation of carbon aerogel in a large system. The fuse and filter arrangement electrically protect the entire system from shutting down if a single pair of electrodes is shorted and mechanically prevents a conducting particle from migrating through the electrode stack, shorting a series of electrode pairs in sequence. It also limits the amount of energy released in a shorting event. The arrangement consists of a set of circuit breakers or fuses with one fuse or breaker in the power line connected to one electrode of each electrode pair and a set of screens of filters in the water flow channels between each set of electrode pairs.

  7. Plasticity in neurological disorders and challenges for noninvasive brain stimulation (NBS

    Mastaglia Frank L

    2009-02-01

    Full Text Available Abstract There has been considerable interest in trialing NBS in a range of neurological conditions, and in parallel the range of NBS techniques available continues to expand. Underpinning this is the idea that NBS modulates neuroplasticity and that plasticity is an important contributor to functional recovery after brain injury and to the pathophysiology of neurological disorders. However while the evidence for neuroplasticity and its varied mechanisms is strong, the relationship to functional outcome is less clear and the clinical indications remain to be determined. To be maximally effective, the application of NBS techniques will need to be refined to take into account the diversity of neurological symptoms, the fundamental differences between acute, longstanding and chronic progressive disease processes, and the differential part played by functional and dysfunctional plasticity in diseases of the brain and spinal cord.

    2002-07-01

    Animal models of neurological deficits are essential for the assessment of new therapeutic options. It has been suggested that rats are not as appropriate as primates for the symptomatic modelling of disease, but a large body of data argues against this view. Comparative analyses of movements in rats and primates show homology of many motor patterns across species. Advances have been made in identifying rat equivalents of akinesia, tremor, postural deficits and dyskinesia, which are relevant to Parkinson's disease. Rat models of hemiplegia, neglect and tactile extinction are useful in assessing the outcome of ischaemic or traumatic brain injury, and in monitoring the effects of therapeutic interventions. Studies in rodents that emphasize careful behavioural analysis should continue to be developed as effective and inexpensive models that complement studies in primates. PMID:12094213

    Life-threatening and benign drug reactions occur frequently in the skin, affecting 8 % of the general population and 2-3 % of all hospitalized patients, emphasizing the need for physicians to effectively recognize and manage patients with drug-induced eruptions. Neurologic medications represent a vast array of drug classes with cutaneous side effects. Approximately 7 % of the United States (US) adult population is affected by adult-onset neurological disorders, reflecting a large number of patients on neurologic drug therapies. This review elucidates the cutaneous reactions associated with medications approved by the US Food and Drug Administration (FDA) to treat the following neurologic pathologies: Alzheimer disease, amyotrophic lateral sclerosis, epilepsy, Huntington disease, migraine, multiple sclerosis, Parkinson disease, and pseudobulbar affect. A search of the literature was performed using the specific FDA-approved drug or drug classes in combination with the terms 'dermatologic,' 'cutaneous,' 'skin,' or 'rash.' Both PubMed and the Cochrane Database of Systematic Reviews were utilized, with side effects ranging from those cited in randomized controlled trials to case reports. It behooves neurologists, dermatologists, and primary care physicians to be aware of the recorded cutaneous adverse reactions and their severity for proper management and potential need to withdraw the offending medication.

    Full Text Available In coffee plantation, solid waste of coffee pulp is usually collected as heap nearby processing facilities for several months prior being used as compost. The practice is leading to the formation of odor and liquid which contaminate the environment. Experiments to evaluate the effect of natural soil ameliorant derived from coffee pulp and minerals were conducted at The Indonesian Coffee and Cocoa Research Institute in Jember, East Java. The experiments were intended to optimize the use of coffee pulp to support farming sustainability and minimize negative impacts of solid waste disposal originated from coffee cherry processing. Prior to applications, coffee pulp was hulled to organic paste. The paste was then mixed with 10% minerals (b/b. Composition of the minerals was 50% zeolite and 50% rock phosphate powder. The ameliorant was characterized for their physical and chemical properties. Agronomic tests were conducted on coffee and cocoa seedling. The experiments were arranged according to Randomized Completely Design with 2 factors, consisted of natural ameliorant and inorganic fertilizer respectively. Natural ameliorant derived from coffee pulp was applied at 6 levels: 0, 30, 60, 90, 120 and 150 g dry ameliorant/seedling of 3 kg soil, equivalent to 0, 1, 2, 3, 4 and 5% (b/b of ameliorant respectively. Inorganic fertilizer was applied at 2 levels: 0 and 2 g fertilizer/application of N-P-K compound fertilizer of 15-15-15 respectively. The inorganic fertilizer was applied 4 times during nursery of coffee and cocoa. The result of the experiment indicated that coffee pulp may be used as natural soil ameliorant. Composition of ameliorant of 90% coffee pulp and 10% of minerals has good physical and chemical characteristics for soil amelioration. The composition has high water holding capacity; cations exchange capacity, organic carbon and phosphorus contents which are favorable to increase soil capacity to support plant growth.

    Full Text Available Introduction: Dermatology is a specialty, which not only deals with dermatological problems with outpatient but also inpatients referrals. The importances of Dermatologist in hospital setting are rising due to changing condition of medical care. Since no peer-reviewed articles are available for dermatological problems in a neurological set up, we conducted this study to know about pattern of skin disorders in neurological patients. Material and Methods: The present study was a prospective study in a neurological setup, which included data from hospital dermatology consultation request forms over a period of one year. The data included demographic profile of the patient investigation where needed, neurological diagnosis and final dermatological diagnosis. The data was analyzed using SPSS. Results: A total of 285 patients who were requested for consultation were included in the study. Face was the commonest site of involvement (19.6%. Laboratory examination of referred patients revealed abnormal blood counts in 2% cases, renal function tests in 0.7% and urine in 0.4% cases. CT scan showed abnormal findings in 65.6% patients. The most common drug used in these patients was phenytoin (29.1%. The most common dermatological diagnosis was Infection and Infestation (34.7% followed by eczema (46.6%. Drug rash was seen in 3.9% cases. Out of which one had phenytoin induced Steven Johnson syndrome. Skin biopsy was done in 5 patients. Topicals was advised in 80%. Upon discharge 10% of inpatients didn’t require any follow-up. The patients who were followed up after 4 weeks, about 48% had their symptoms resolved with topicals and oral treatment as required. About 38% required more than two follow ups due to chronic course of the diseases. Conclusions: This present study discussed about various manifestations of skin disorders in a neurological set up and emphasizes the role of dermatologist in treating skin problems both in outpatient as well as inpatient

  19. Evaluation of neurological complications using who warning signs for dengue disease severity

    International Nuclear Information System (INIS)

    In 2009 a new classification of dengue was proposed by WHO Tropical Disease Research, which classifies dengue into dengue (D), dengue with warning signs (DW) and severe dengue (SD). This classification highlights the warning signs of dengue disease severity. Neurological complications are one of the most serious complications of dengue disease. This study was carried out to see association of neurological complications of dengue patients with WHO warning signs for dengue disease severity, and their outcome. Methods: It was a cross-sectional analytical study and included 180 diagnosed and registered cases of dengue hemorrhagic fever. The participants were subjected to a detailed clinical evaluation, laboratory assessment including blood counts, hematocrit, serology for dengue fever and sonography at 24 hours and 48 hours of their admission. Results: Twenty-six percent patients were suffering from neurological complications due to dengue. The warning signs for dengue disease severity like altered sensorium (85.5%, p=0.001), raised hematocrit (n=47, p=0.029), gall bladder wall thickening, pleural effusion and ascites on sonographic report (n=47, p=0.024), were strongly associated with the neurological complications. Conclusion: Our study reveals significant association of WHO warning signs for dengue disease severity with neurological complications of dengue disease. (author)

    Neurological complications after cardiac arrest (CA) can be fatal. Although hypothermia has been shown to be beneficial, understanding the mechanism and establishing neurological outcomes remains challenging because effects of CA and hypothermia are not well characterized. This paper aims to analyze EEG (and the alpha-rhythms) using multiscale entropy (MSE) to demonstrate the ability of MSE in tracking changes due to hypothermia and compare MSE during early recovery with long-term neurological examinations. Ten Wistar rats, upon post-CA resuscitation, were randomly subjected to hypothermia (32 degrees C-34 degrees C, N = 5) or normothermia (36.5 degrees C-37.5 degrees C, N = 5). EEG was recorded and analyzed using MSE during seven recovery phases for each experiment: baseline, CA, and five early recovery phases (R1-R5). Postresuscitation neurological examination was performed at 6, 24, 48, and 72 h to obtain neurological deficit scores (NDSs). Results showed MSE to be a sensitive marker of changes in alpha-rhythms. Significant difference (p < 0.05) was found between the MSE for two groups during recovery, suggesting that MSE can successfully reflect temperature modulation. A comparison of short-term MSE and long-term NDS suggested that MSE could be used for predicting favorability of long-term outcome. These experiments point to the role of cortical rhythms in reporting early neurological response to ischemia and therapeutic hypothermia. PMID:19174339

    2016-01-01

    The majority of neonatal seizures are of acute symptomatic origin, and their occurrence is associated with higher mortality and morbidity compared with the general population, even if there is conflicting evidence of a detrimental effect per se. Etiology is considered the main determinant of outcome, but other factors, including gestational age, brain damage severity, neonatal neurological examination, and electroencephalographically (EEG) interictal and ictal characteristics are also related to neurodevelopmental outcome or death. Therefore, accuracy in early prognostication since the neonatal period can be improved by conveniently integrating different clinical and instrumental findings.The aim of this review is first to review the outcome of newborns with seizures (mortality, epilepsy, cerebral palsy, and intellectual disability), second to review the risk factors for adverse outcome after seizures in the newborn period, considering clinical, EEG/amplitude-integrated EEG, and neuroimaging findings associated with adverse outcome and lack of response to treatment, and finally to review published scoring systems for predicting neurologic outcome after neonatal seizures.

    The central nervous system regulates food intake, homoeostasis of glucose and electrolytes, and starts the sensations of hunger and satiety. Different nutritional factors are involved in the pathogenesis of several neurological diseases. Patients with acute neurological diseases (traumatic brain injury, cerebral vascular accident hemorrhagic or ischemic, spinal cord injuries, and cancer) and chronic neurological diseases (Alzheimer's Disease and other dementias, amyotrophic lateral sclerosis, Parkinson's Disease) increase the risk of malnutrition by multiple factors related to nutrient ingestion, abnormalities in the energy expenditure, changes in eating behavior, gastrointestinal changes, and by side effects of drugs administered. Patients with acute neurological diseases have in common the presence of hyper metabolism and hyper catabolism both associated to a period of prolonged fasting mainly for the frequent gastrointestinal complications, many times as a side effect of drugs administered. During the acute phase, spinal cord injuries presented a reduction in the energy expenditure but an increase in the nitrogen elimination. In order to correct the negative nitrogen balance increase intakes is performed with the result of a hyper alimentation that should be avoided due to the complications resulting. In patients with chronic neurological diseases and in the acute phase of cerebrovascular accident, dysphagia could be present which also affects intakes. Several chronic neurological diseases have also dementia, which lead to alterations in the eating behavior. The presence of malnutrition complicates the clinical evolution, increases muscular atrophy with higher incidence of respiratory failure and less capacity to disphagia recuperation, alters the immune response with higher rate of infections, increases the likelihood of fractures and of pressure ulcers, increases the incapacity degree and is an independent factor to increase mortality.

    Full Text Available Background: In the context of inadequacy of neurology workforce in India, it is important to understand factors that post-graduate medical students consider for and against choosing neurology as their career option. Understanding these factors will help in planning strategies to encourage students to pursue a career in neurology. At present, there is a paucity of studies addressing this issue in India. Aims and Objectives: (1 To analyze factors, which post-graduate students consider for and against choosing neurology as a career specialty. (2 To access the level and quality of neurology exposure in the current MBBS and MD curricula. Materials and Methods: Statewide questionnaire based study was conducted in the state of Maharashtra for students eligible to take DM neurology entrance examination (MD Medicine and MD Pediatrics. Results: In this survey, 243 students were enrolled. Factors bringing students to neurology were - intellectual challenge and logical reasoning (72%, inspired by role model teachers (63%, better quality-of-life (51% and scope for independent practice without expensive infrastructure (48%. Factors preventing students from taking neurology were - perception that most neurological diseases are degenerative (78%, neurology is mainly an academic specialty (40%, neurophobia (43% and lack of procedures (57%. Inadequate exposure and resultant lack of self-confidence were common (31%, 70-80%. 84% of the students felt the need for a short term certification course in neurology after MD. Conclusions: To attract more students to neurology, "role model" teachers of neurology could interact and teach students extensively. Neurologists′ efforts to shed their diagnostician′s image and to shift their focus to therapeutics will help change the image of neurology. Out-patient neurology clinics should be incorporated early in the student′s career. Procedures attract students; hence, they should be made conversant with procedures and

    Full Text Available Abstract The outcome of pediatric hydrocephalus, including surgical complications, neurological sequelae and academic achievement, has been the matter of many studies. However, much uncertainty remains, regarding the very long-term and social outcome, and the determinants of complications and clinical outcome. In this paper, we review the different facets of outcome, including surgical outcome (shunt failure, infection and independence, and complications of endoscopy, clinical outcome (neurological, sensory, cognitive sequels, epilepsy, schooling and social integration. We then provide a brief review of the English-language literature and highlighting selected studies that provide information on the outcome and sequelae of pediatric hydrocephalus, and the impact of predictive variables on outcome. Mortality caused by hydrocephalus and its treatments is between 0 and 3%, depending on the duration of follow-up. Shunt event-free survival (EFS is about 70% at one year and 40% at ten years. The EFS after endoscopic third ventriculostomy (ETV appears better but likely benefits from selection bias and long-term figures are not available. Shunt infection affects between 5 and 8% of surgeries, and 15 to 30% of patients according to the duration of follow-up. Shunt independence can be achieved in 3 to 9% of patients, but the definition of this varies. Broad variations in the prevalence of cognitive sequelae, affecting 12 to 50% of children, and difficulties at school, affecting between 20 and 60%, attest of disparities among studies in their clinical evaluation. Epilepsy, affecting 6 to 30% of patients, has a serious impact on outcome. In adulthood, social integration is poor in a substantial number of patients but data are sparse. Few controlled prospective studies exist regarding hydrocephalus outcomes; in their absence, largely retrospective studies must be used to evaluate the long-term consequences of hydrocephalus and its treatments.

    The promise of stem cell regeneration has been the hope of many neurologic patients with permanent damage to the central nervous system. There are hundreds of stem cell trials worldwide intending to test the regenerative capacity of stem cells in various neurological conditions from Parkinson׳s disease to multiple sclerosis. Although no stem cell therapy is clinically approved for use in any human disease indication, patients are seeking out trials and asking clinicians for guidance. This review summarizes the current state of regenerative stem cell transplantation divided into seven conditions for which trials are currently active: demyelinating diseases/spinal cord injury, amyotrophic lateral sclerosis, stroke, Parkinson׳s disease, Huntington׳s disease, macular degeneration and peripheral nerve diseases.

    Technological development has paved the way for accelerated genomic discovery and is bringing precision medicine into view. The goal of precision medicine is to deliver optimally targeted and timed interventions tailored to an individual's molecular drivers of disease. Neurological diseases are promisingly suited models for precision medicine because of the rapidly expanding genetic knowledge base, phenotypic classification, the development of biomarkers and the potential modifying treatments. Moving forward, it is crucial that through these integrated research platforms to provide analysis both for accurate personal genome analysis and gene and drug discovery. Here we describe our vision of how precision medicine can bring greater clarity to the clinical and biological complexity of neurological diseases. PMID:27127757

Neuroimaging (CT and/or MRI revealed symmetrical occipital lesions in all. One patient had a large pontine lesion. Seizure control was achieved in all with intravenous phenytoin. All patients recovered fully without any residual neurological deficit and their radiological brain lesions resolved completely, in all except one case. The neurological manifestations and neuroimaging features in cases of eclampsia have been reviewed. A brief note on the pathogenesis of the cerebral lesions is included and the controversial aspect of seizure control in eclampsia highlighted.

    As neurologists and neuroscientists, we are trained to evaluate disorders of the nervous system by thinking systematically. Clinically, we think in terms of cognition, behavior, motor function, sensation, balance and co-ordination, and autonomic system function. But when we assess symptoms of neurological disorders for the purpose of drug development, we tend to create disease-specific outcome measures, often using a variety of methods to assess the same types of dysfunction in overlapping, r...

    Toxigenic mold activities produce metabolites that are either broad-spectrum antibiotics or mycotoxins that are cytotoxic. Indoor environmental exposure to these toxigenic molds leads to adverse health conditions with the main outcome measure of frequent neuroimmunologic and behavioral consequences. One of the immune system disorders found in patients presenting with toxigenic mold exposure is an abnormal natural killer cell activity.

    Prediction of prognosis in comatose patients surviving a cardiac arrest is still one of the intractable problems in critical care neurology because of lack of fool-proof ways to assess the outcome. Of all these measures, somatosensory-evoked potential (SSEP) has been perhaps the most evaluated and heavily relied-upon tool over the past several decades for assessing coma. Recent studies have given rise to concerns regarding the “absoluteness” of SSEP signals for the prognostic evaluation of co...

  15. Chapter 40: history of neurology in France.

    Science.gov (United States)

    Clarac, François; Boller, François

    2010-01-01

    The history of neurology in France is characterized by the very high degree of centralization in that country where "everything seems to happen in Paris," and yet the considerable degree of autonomous diversity in the evolution of some other medical schools such as Montpellier and Strasbourg. It could be argued that France saw the birth of clinical neurology as a separate discipline since Jean Martin Charcot at the Salpêtrière Hospital obtained a chair of diseases of the nervous system in 1892, a first in the history of the academic world. The chapter shows, however, that the work of Charcot was preceded by a long evolution in medical thinking, which culminated with the introduction of experimental medicine developed by Claude Bernard and François Magendie, and by the study of aphasia by Paul Broca and its localization of language in a specific area of the brain. Many of the great neurologists of France like Duchenne de Boulogne, Gilles de la Tourette, Joseph Babinski and Pierre Marie gravitated around Charcot while others like Charles-Edward Brown-Sequard and Jules Dejerine developed their talents independently. The history of Sainte-Anne Hospital further illustrates this independence. It also shows the relation between neurology and psychiatry with Henri Ey, Jean Delay and Pierre Deniker, who collaborated with Henri Laborit in the clinical development of chlorpromazine. Sainte Anne also saw the birth of modern neuropsychology with Henry Hécaen. Jean Talairach and his group developed human stereotaxic neurosurgery and a 3-dimensional brain atlas that is used around the world. The chapter also mentions institutions (the CNRS and INSERM) that have contributed to developments partially independently from medical schools. It concludes with a presentation of schools located outside of Paris that have played a significant role in the development of neurology. Six of the most important ones are described: Montpellier, Toulouse, Bordeaux, Strasbourg, Lyon, and

  17. Epigenetic mechanisms in neurological and neurodegenerative diseases.

    2015-02-01

    Full Text Available The role of epigenetic mechanisms in the function and homeostasis of the central nervous system (CNS and its regulation in diseases is one of the most interesting processes of contemporary neuroscience. In the last decade, a growing body of literature suggests that long-term changes in gene transcription associated with CNS´s regulation and neurological disorders are mediated via modulation of chromatin structure.Epigenetics, introduced for the first time by Waddington in the early 1940s, has been traditionally referred to a variety of mechanisms that allow heritable changes in gene expression even in the absence of DNA mutation. However, new definitions acknowledge that many of these mechanisms used to perpetuate epigenetic traits in dividing cells are used by neurons to control a variety of functions dependent on gene expression. Indeed, in the recent years these mechanisms have shown their importance in the maintenance of a healthy CNS. Moreover, environmental inputs that have shown effects in CNS diseases, such as nutrition, that can modulate the concentration of a variety of metabolites such as acetyl-coenzyme A (acetyl-coA, nicotinamide adenine dinucleotide (NAD+ and beta hydroxybutyrate (β-HB, regulates some of these epigenetic modifications, linking in a precise way environment with gene expression.This manuscript will portray what is currently understood about the role of epigenetic mechanisms in the function and homeostasis of the CNS and their participation in a variety of neurological disorders. We will discuss how the machinery that controls these modifications plays an important role in processes involved in neurological disorders such as neurogenesis and cell growth. Moreover, we will discuss how environmental inputs modulate these modifications producing metabolic and physiological alterations that could exert beneficial effects on neurological diseases. Finally, we will highlight possible future directions in the field of

    Nanotechnology involves probing and manipulating matter at the molecular level. Nanotechnology based molecular diagnostics have the potential to alleviate the suffering caused by many diseases, including neurological disorders, due to the unique properties of nanomaterials. Most neurological illnesses are multifactorial conditions and many of these are also classified as neurobehavioral disorders. Alzheimer's disease, Parkinson's disease, Huntington disease, cerebral ischemia, epilepsy, schizophrenia and autism spectrum disorders like Rett syndrome are some examples of neurological disorders that could be better treated, diagnosed, prevented and possibly cured using nanotechnology. In order to improve the quality of life for disease afflicted people, a wide range of nanomaterials that include gold and silica nanoparticles, quantum dots and DNA along with countless other forms of nanotechnology have been investigated regarding their usefulness in advancing molecular diagnostics. Other small scaled materials like viruses and proteins also have potential for use as molecular diagnostic tools. Information obtained from nanotechnology based diagnostics can be stored and manipulated using bioinformatics software. More advanced nanotechnology based diagnostic procedures for the acquisition of even greater proteomic and genomic knowledge can then be developed along with better ways to fight various diseases. Nanotechnology also has numerous applications besides those related to biotechnology and medicine. In this article, we will discuss and analyze many novel nanotechnology based diagnostic techniques at our disposal today. (author)

    Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by epistaxis, telangiectases, and multi-organ vascular dysplasia. Head and neck localizations of HHT are recurrent, frequent associated with serious complications. The aim of this study was to describe the clinical and imaging patterns of neurological involvement in HHT and to discuss the role of interventional radiology in the management of HHT patients. Based on a multidisciplinary experience of twenty years at our center, we report here the different aspects of neurological involvement of HHT. Depending on the genetic type of the disease, vascular abnormalities may affect different organs. The knowledge of neurological involvement according to specific localization of HHT makes detection easier. As cerebral or spinal arteriovenous fistula may be present in patients with epistaxis or pulmonary arteriovenous malformations (PAVMs), radiologists should be able to detect high-risk lesions and prevent related complications. Finally, we review indications and techniques of embolization for hemorrhagic lesions and emphasize that endovascular therapies are very effective and safe in experienced hands. Head and neck imaging is commonly used for the diagnosis of HHT. Imaging plays also a key role for patient evaluation before treatment as pluridisciplinary management is needed. PMID:27059009

    The import of the cavum variation and its prevalence rate in healthy individuals is still not clear, likewise in neurologically diseased patients. To evaluate the frequency and pattern of caval variations in neurologically diseased patients. The presence or absence of the cavum septum pellucidum (CSP), cavum vergae (CV), or cavum velum interpositum (CVI) was reviewed from successive cranial computerized tomography (CT) images of patients who were aged 6 months and above. Two hundred and seventeen cranial CT images were reviewed. At least a cavum variation was noted in 130 (59.9%) of the CT scan images reviewed. The CV, CVI, and CSP were noted in 86 (39.6%), 53 (24.4%), and 50 images (23%), respectively. Caval multiplicity was noted in 102 patients (47%). There was no significant difference in the rate of occurrence of cavum variations in patients with congenital brain diseases and acquired brain conditions (P = 0.484), neither was there a significant difference in the frequency of cavum variation in children aged older than 6 months compared to adults (P = 0.101). Cava variations are relatively common in neurological brain diseases. Patients with congenital brain diseases did not have a higher frequency of cava variation when compared with those that had acquired lesions. The most common type of cavum variation noted in this study was the vergae variety, while the CSP is the rarest

    We report a patient driven home care system that successfully assisted 24/7 with the management of a 68-year-old woman after a stroke-a global illness. The patient's caregiver and physician used computer devices, smartphones and internet access for information exchange. Patient, caregiver, family and physician satisfaction, coupled with outcome and cost were indictors of quality of care. The novelty of this basic model of teleneurology is characterised by implementing a patient/caregiver driven system designed to improve access to cost-efficient neurological care, which has potential for use in primary, secondary and tertiary levels of healthcare in rural and underserved regions of the world. We suggest involvement of healthcare stakeholders in teleneurology to address this global problem of limited access to neurological care. This model can facilitate the management of neurological diseases, impact on outcome, reduce frequency of consultations and hospitalisations, facilitate teaching of healthcare workers and promote research.

    A number of health and lifestyle factors are thought to contribute to cognitive decline associated with age but cannot be easily modified by the individual patient. We identified 12 individually modifiable interventions that can be implemented during midlife or later with the potential to ameliorate cognitive aging. For ten of these, we used PubMed databases for a systematic review of long-duration (at least 6 months), randomized, controlled trials in midlife and older adults without dementia or mild cognitive impairment with objective measures of neuropsychological performance. Using network meta-analysis, we performed a quantitative synthesis for global cognition (primary outcome) and episodic memory (secondary outcome). Of 1038 publications identified by our search strategy, 24 eligible trials were included in the network meta-analysis. Results suggested that the Mediterranean diet supplemented by olive oil and tai chi exercise may improve global cognition, and the Mediterranean diet plus olive oil and soy isoflavone supplements may improve memory. Effect sizes were no more than small (standardized mean differences 0.11-0.22). Cognitive training may have cognitive benefit as well. Most individually modifiable risk factors have not yet been adequately studied. We conclude that some interventions that can be self-initiated by healthy midlife and older adults may ameliorate cognitive aging. PMID:26361790

    Full Text Available Accidents are a major public health concern, resulting in an estimated 1.2 million deaths and 50 million injuries worldwide each year specifically, the relationships between drivers' characteristics and road accidents are not fully understood. Many factors are involved in the accident occurrence at construction site. Some important elements that create a significant portion of accidents include: safety management error, poor training programs, human element, act of god, outdated procedure and no clear monitoring policy. Although some of these items are inevitable, but the occurrence of the largest part can be prevented. Therefore, for ameliorating the safety in a project each of these items should be analyzed and a practical approach introduced. In general, near miss, incident and accident are three dependent levels that mainly lead to injury. Risk and hazard are allocated in first level which means near miss, therefore, no on-time identification of hazard and risk causes to create incident and preventing accident in incident stage is unavoidable.

  4. Riboflavin ameliorates cisplatin induced toxicities under photoillumination.

    Directory of Open Access Journals (Sweden)

    Iftekhar Hassan

    Full Text Available BACKGROUND: Cisplatin is an effective anticancer drug that elicits many side effects mainly due to induction of oxidative and nitrosative stresses during prolonged chemotherapy. The severity of these side effects consequently restricts its clinical use under long term treatment. Riboflavin is an essential vitamin used in various metabolic redox reactions in the form of flavin adenine dinucleotide and flavin mononucleotide. Besides, it has excellent photosensitizing property that can be used to ameliorate these toxicities in mice under photodynamic therapy. METHODS AND FINDINGS: Riboflavin, cisplatin and their combinations were given to the separate groups of mice under photoilluminated condition under specific treatment regime. Their kidney and liver were excised for comet assay and histopathological studies. Furthermore, Fourier Transform Infrared Spectroscopy of riboflavin-cisplatin combination in vitro was also conducted to investigate any possible interaction between the two compounds. Their comet assay and histopathological examination revealed that riboflavin in combination with cisplatin was able to protect the tissues from cisplatin induced toxicities and damages. Moreover, Fourier Transform Infrared Spectroscopy analysis of the combination indicated a strong molecular interaction among their constituent groups that may be assigned for the protective effect of the combination in the treated animals. CONCLUSION: Inclusion of riboflavin diminishes cisplatin induced toxicities which may possibly make the cisplatin-riboflavin combination, an effective treatment strategy under chemoradiotherapy in pronouncing its antineoplastic activity and sensitivity towards the cancer cells as compared to cisplatin alone.

  5. [Development of neurology in Germany after 1960].

    Science.gov (United States)

    2013-12-01

    The still continuing accelerated development of neurology in Germany is described in this article by a contemporary witness who was active in this field from 1965 to 2005. The personal experiences of the author are obviously only reflected over these 40 years so that the glorious antecedents in the period up to 1933, the era in which our predecessors were the world leaders in neurology, is not sufficiently covered. This dominance was lost by the anti-Semitism during the era of National Socialism and the sequelae of World War II. As a result of the war, German neurologists became effectively isolated and their participation in international congresses was forbidden so that a gradual reestablishment of alignment only became possible after 1960. In this brief description no attempt at completeness has been made and only subjectivity and brevity have been considered. An attempt is made to retrospectively convey what essentially happened. An exact dating of advances over the period was sometimes difficult. The readership will have the opportunity to share the surprise of the author on how meagre the neurological knowledge and diagnostic methods were 50 years ago, how rapidly the subsequent development happened, how rapidly things became obvious which 20 years ago nobody was aware of and despite the progress how pleased we were to find ourselves at the most recent state of error and probably still find ourselves nowadays. In particular, how powerless and untested the therapeutic efforts were at that time. The progress can only be measured by a comparison between then, 50 years ago and the present. A projection of the future based on these experiences is not attempted but it seems to be certain that many conceptions, diagnostic advances and therapy options are still undiscovered and that further exciting times can be expected.

    Duke, Lynsay; Gibbison, Lucy; McMahon, Victoria

    Caring for hands tightened by spasticity after stroke, brain injury or other neurological conditions can be challenging for care staff. Opening and cleaning the hand, managing pressure areas, cutting nails and reducing pain becomes more complex if muscles are tight and short. Hand hygiene is key for staff but literature on patients' hand and nail care is lacking, so specialist education and care planning may be needed to help staff ensure these activities are done well. This article outlines the importance of maintaining patients' hand hygiene, explores the barriers to providing effective care and discusses how they might be overcome. PMID:26665632

    Full Text Available Analgesia and sedation has been widely used in intensive care units where iatrogenic discomfort often complicates patient management. In neurological patients maximal comfort without diminishing patient responsiveness is desirable. In these patients successful management of sedation and analgesia incorporates a patient based approach that includes detection and management of predisposing and causative factors, including delirium, monitoring using sedation scales, proper medication selection, emphasis on analgesia based drugs and incorporation of protocols or algorithms. So, to optimize care clinician should be familiar with the pharmacokinetic and pharmacodynamic variables that can affect the safety and efficacy of analgesics and sedatives.

    Globally, there is a crucial need to prioritize research directed at reducing neurological, mental health and substance-use disorders in adolescence, which is a pivotal age for the development of self-control and regulation. In adolescence, behaviour optimally advances towards adaptive long-term goals and suppresses conflicting maladaptive short-lived urges to balance impulsivity, exploration and defiance, while establishing effective societal participation. When self-control fails to develop, violence, injury and neurological, mental health and substance-use disorders can result, further challenging the development of self-regulation and impeding the transition to a productive adulthood. Adolescent outcomes, positive and negative, arise from both a life-course perspective and within a socioecological framework. Little is known about the emergence of self-control and regulation in adolescents in low- and middle-income countries where enormous environmental threats are more common (for example, poverty, war, local conflicts, sex trafficking and slavery, early marriage and/or pregnancy, and the absence of adequate access to education) than in high-income countries and can threaten optimal neurodevelopment. Research must develop or adapt appropriate assessments of adolescent ability and disability, social inclusion and exclusion, normative development, and neurological, mental health and substance-use disorders. Socioecological challenges in low- and middle-income countries require innovative strategies to prevent mental health, neurological and substance-use disorders and develop effective interventions for adolescents at risk, especially those already living with these disorders and the consequent disability.

    Background Team-based learning (TBL), a new active learning method, has not been reported for neurology education. We aimed to determine if TBL was more effective than passive learning (PL) in improving knowledge outcomes in two key neurology topics - neurological localization and neurological emergencies. Methods We conducted a modified crossover study during a nine-week internal medicine posting involving 49 third-year medical undergraduates, using TBL as the active intervention, compared against self-reading as a PL control, for teaching the two topics. Primary outcome was the mean percentage change in test scores immediately after (post-test 1) and 48 hours after TBL (post-test 2), compared to a baseline pre-test. Student engagement was the secondary outcome. Results Mean percentage change in scores was greater in the TBL versus the PL group in post-test 1 (8.8% vs 4.3%, p = 0.023) and post-test 2 (11.4% vs 3.4%, p = 0.001). After adjustment for gender and second year examination grades, mean percentage change in scores remained greater in the TBL versus the PL group for post-test 1 (10.3% vs 5.8%, mean difference 4.5%,95% CI 0.7 - 8.3%, p = 0.021) and post-test 2 (13.0% vs 4.9%, mean difference 8.1%,95% CI 3.7 - 12.5%, p = 0.001), indicating further score improvement 48 hours post-TBL. Academically weaker students, identified by poorer examination grades, showed a greater increase in scores with TBL versus strong students (p < 0.02). Measures of engagement were high in the TBL group, suggesting that continued improvements in scores 48 hours post-TBL may result from self-directed learning. Conclusions Compared to PL, TBL showed greater improvement in knowledge scores, with continued improvement up to 48 hours later. This effect is larger in academically weaker students. TBL is an effective method for improving knowledge in neurological localization and neurological emergencies in undergraduates. PMID:22035246

    Hyponatremia is the most common clinical electrolyte disorder. Once thought to be asymptomatic in response to adaptation by the brain, recent evidence suggests that chronic hyponatremia may be linked to attention deficits, gait disturbances, risk of falls, and cognitive impairments. Such neurologic defects are associated with a reduction in quality of life and may be a significant cause of mortality. However, because underlying diseases such as adrenal insufficiency, heart failure, liver cirrhosis, and cancer may also affect brain function, the contribution of hyponatremia alone to neurologic manifestations and the underlying mechanisms remain unclear. Using a syndrome of inappropriate secretion of antidiuretic hormone rat model, we show here that sustained reduction of serum sodium ion concentration induced gait disturbances; facilitated the extinction of a contextual fear memory; caused cognitive impairment in a novel object recognition test; and impaired long-term potentiation at hippocampal CA3-CA1 synapses. In vivo microdialysis revealed an elevated extracellular glutamate concentration in the hippocampus of chronically hyponatremic rats. A sustained low extracellular sodium ion concentration also decreased glutamate uptake by primary astrocyte cultures, suggesting an underlying mechanism of impaired long-term potentiation. Furthermore, gait and memory performances of corrected hyponatremic rats were equivalent to those of control rats. Thus, these results suggest chronic hyponatremia in humans may cause gait disturbance and cognitive impairment, but these abnormalities are reversible and careful correction of this condition may improve quality of life and reduce mortality.

    Full Text Available Neurological disorders have become more common and prevalent. Cellular pathology and behavioural symptoms in neurodegenerative diseases although connected are still a mystery to solve with no complete cure available yet. Central pathways in neurodegeneration involves impaired ubiquitin-proteasome machinery, autophagy and mitochondrial oxidative stress. In the case of neurodevlopmental disorders, environmental toxins and genetic factors are main causative agents. We aim to create a toxicity induced zebrafish model of neurological disease focussing on cognition, movement and hyperactivity disorders. Zebra fish embryos at 48 hr post fertilization were treated with different doses of lead, cholesterol and acetyl choline and by 7 days post fertilization pectoral fin movement, swimming behaviour and touch response were compromised in parallel with apoptosis identified in the brain by acridine orange fluorescent staining. A marked window is observed, therefore promising for a drug screening platform. Further characterization of pathology associated protein expression and specific behavioural studies could render this as a simple promising toxic model for preclinical drug screening.

  12. Neurological manifestations of Batch s disease

    International Nuclear Information System (INIS)

    To determine the prevalence, clinical manifestations, and laboratory features of Neuro-Behcets disease. This prospective study was carried out in the Behcets Research Clinic in Shiraz (south-west Iran) and included the patients referred from 1990-1999. The patients' clinical records, images, CSF analyses, and electrodiagnostic studies were reviewed. Eighteen (15 males and 3 females) out of 690 Behcet s patients (2.6%, 95% CI = 1.4-3.8%) were found to have neurological involvement. The mean +/- standard deviation age of these patients was 34.7 +/- 8.6 years. All fulfilled the criteria of the International Study Group of Behcet s Disease. Central nervous system involvement was more common than peripheral nervous system manifestations. Headache, weakness, tingling, and numbness were the most common symptoms. Hyperreflexia, upward plantar reflex, and somatosensory findings were the most frequent signs. Hemispheral and brainstem stroke-like syndromes and cerebral venous thrombosis were the major neurologic presentations. There were also cases of myelitic, pure meningoencephalitic, amyotrophic lateral sclerosis-like, multiple sclerosis-like, and Guillain Barre syndromes. Neuro-Behcets disease must be considered in the differential diagnosis of stroke in young adults, chronic meningitis, intracranial hypertension, multiple sclerosis, myelopathies, and peripheral neuropathies.

    Intravenous immunoglobulin (IVIg) is used increasingly in the management of patients with neurological conditions. The efficacy and safety of IVIg treatment in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and Guillain-Barré syndrome (GBS) have been established clearly in randomized controlled trials and summarized in Cochrane systematic reviews. However, questions remain regarding the dose, timing and duration of IVIg treatment in both disorders. Reports about successful IVIg treatment in other neurological conditions exist, but its use remains investigational. IVIg has been shown to be efficacious as second-line therapy in patients with dermatomyositis and suggested to be of benefit in some patients with polymyositis. In patients with inclusion body myositis, IVIg was not shown to be effective. IVIg is also a treatment option in exacerbations of myasthenia gravis. Studies with IVIg in patients with Alzheimer's disease have reported increased plasma anti-Abeta antibody titres associated with decreased Abeta peptide levels in the cerebrospinal fluid following IVIg treatment. These changes at the molecular level were accompanied by improved cognitive function, and large-scale randomized trials are under way. PMID:19883422

    Many aspects of fertility rely on intact neurologic function and thus neurologic diseases can result in infertility. While research into general female fertility and alterations in male semen quality is limited, we have an abundance of knowledge regarding ejaculatory dysfunction following nerve injury. Normal ejaculation is the result of coordinated reflex activity involving both the sympathetic and somatic nervous systems. Nerve injury can result in retrograde ejaculation, and anejaculation. With retrograde ejaculation, the ejaculate is propelled into the bladder instead of out through the urethra. In mild cases this condition can be reversed by sympathomimetic medications and, in more severe cases, sperm cells can be extracted from the bladder following ejaculation. With anejaculation, the ejaculatory reflex is not activated by normal sexual stimulation. In such cases, the first choice of treatment is assisted ejaculation, preferably by penile vibratory stimulation. If vibratory stimulation is unsuccessful, then ejaculation can almost always be induced by electroejaculation. In cases where assisted ejaculation fails, sperm can be retrieved surgically from either the epididymis or from the testis. Once viable sperm cells have been obtained, these are used in assisted reproductive techniques, including intravaginal insemination, intrauterine insemination, and in vitro fertilization/intracytoplasmic sperm injection.

    Chronic hepatitis C virus (HCV) infection exhibits a wide range of extrahepatic complications, affecting various organs in the human body. Numerous HCV patients suffer neurological manifestations, ranging from cognitive impairment to peripheral neuropathy. Overexpression of the host immune response leads to the production of immune complexes, cryoglobulins, as well as autoantibodies, which is a major pathogenic mechanism responsible for nervous system dysfunction. Alternatively circulating inflammatory cytokines and chemokines and HCV replication in neurons is another factor that severely affects the nervous system. Furthermore, HCV infection causes both sensory and motor peripheral neuropathy in the mixed cryoglobulinemia as well as known as an important risk aspect for stroke. These extrahepatic manifestations are the reason behind underlying hepatic encephalopathy and chronic liver disease. The brain is an apt location for HCV replication, where the HCV virus may directly wield neurotoxicity. Other mechanisms that takes place by chronic HCV infection due the pathogenesis of neuropsychiatric disorders includes derangement of metabolic pathways of infected cells, autoimmune disorders, systemic or cerebral inflammation and alterations in neurotransmitter circuits. HCV and its pathogenic role is suggested by enhancement of psychiatric and neurological symptoms in patients attaining a sustained virologic response followed by treatment with interferon; however, further studies are required to fully assess the impact of HCV infection and its specific antiviral targets associated with neuropsychiatric disorders.

    Aminopyridines are members of a family of monoamino and diamino derivatives of pyridine, and their principal mechanism of action is dose-dependent blockade of voltage-gated potassium channels, in particular, fast voltage-gated potassium channels. To date, only 2 main broad-spectrum potassium channel blockers, 4-aminopyridine (4-AP) and 3,4-diaminopyridine (3,4-DAP), have been used as investigational new drugs in various neurological diseases. More recently, licensed versions of these compounds including dalfampridine extended release (Fampyra, Biogen Idec) for the improvement of walking in adult patients with multiple sclerosis, and amifampridine (Firdapse, Biomarin Europe Ltd) for the treatment of Lambert-Eaton myasthenic syndrome have been released, and the costs associated with using these new products highlights the importance of evaluating the clinically meaningful treatment effects of these drugs.The current review summarizes the evidence of aminopyridine use in neurological conditions and in particular presents a systematic review of all randomized trials of 3,4-DAP in Lambert-Eaton myasthenic syndrome to determine the efficacy of this treatment using meta-analysis of clinical and electrophysiological end points.

    Person-oriented medicine is characterized by a holistic approach in patient ma- nagement that embraces physical, psychological, social and spiritual aspects of health and dise- ase. It responds to the needs of patients and health care workers to form an effective therapeutic relationship based on trust, empathy, compassion and responsiveness to the individual needs of a patient. Person-oriented perspectives in neurology include active collaborative partnership between a physician and a patient, and intuitive perception, which has a neurobiological correlate in the hu- man mirror neuron system, thus expressing a considerable impact on the quality of the physician's diagnostic and therapeutic activities. On the other hand, personalized approach in medicine implies integration of clinical information and personal genotyping. Personalized neurology provides gene- based preclinical prediction of disease with improved risk assessment, early detection of disease and targeted intervention. The combination of personalized approach and clinical information accelera- tes the translation of genetic discoveries into clinical practice, which ultimately results in improved health care system. Person-oriented perspectives contribute significantly to the growing pluralism of medical science and provide a greater humanization of medicine, individualized treatment and autonomy during therapeutic processes.

    Early neurology in German-speaking countries evolved aside from mainstream medicine. Animists like Stahl in the 18th century saw the soul as the cause of health and disease, and the later Vitalists insisted on life-force as the specific property of living beings, contrary to skeptics like Albrecht von Haller, whose neurophysiology they left behind. Following Willis, they studied brain tracts and speculated about reflex action. They experimented with electrotherapy, and later devised early theories of electric nerve action. The controversial medical theories of animal magnetism and phrenology also advanced brain research and clinical neurology together with their sectarian programs, which seem absurd today. The impact on natural science and medicine of the last great Vitalist, Johannes Müller, and his mechanistic students such as Remak, Schwann, Schleiden, Helmholtz, Ludwig, Brücke, Virchow, Koelliker, and Wundt was unparalleled. They provided the anatomical and physiological infrastructure for the growth of neurology. From 1845 far into the 20th century, psychiatry and neurology evolved together. Neuropsychiatrists cared for their mental patients during the day, and studied their brain tissue slides at night, as in the case of Alzheimer and Nissl. Major advances in brain research were achieved by the hypnotists Forel and Vogt, and modern psychiatry was launched by the typical neuropsychiatrists Kraepelin, Moebius, Bleuler, and Adolf Meyer.

    Chronic exposure to low-levels of organophosphate (OP) compounds, such as chlorpyrifos (CPF), induces oxidative stress and could be related to neurological disorders. Hydrogen has been identified as a novel antioxidant which could selectively scavenge hydroxyl radicals. We explore whether intake of hydrogen-rich water (HRW) can protect Wistar rats from CPF-induced neurotoxicity. Rats were gavaged daily with 6.75 mg/kg body weight (1/20 LD{sub 50}) of CPF and given HRW by oral intake. Nissl staining and electron microscopy results indicated that HRW intake had protective effects on the CPF-induced damage of hippocampal neurons and neuronal mitochondria. Immunostaining results showed that the increased glial fibrillary acidic protein (GFAP) expression in astrocytes induced by CPF exposure can be ameliorated by HRW intake. Moreover, HRW intake also attenuated CPF-induced oxidative stress as evidenced by enhanced level of MDA, accompanied by an increase in GSH level and SOD and CAT activity. Acetylcholinesterase (AChE) activity tests showed significant decrease in brain AChE activity after CPF exposure, and this effect can be ameliorated by HRW intake. An in vitro study demonstrated that AChE activity was more intense in HRW than in normal water with or without chlorpyrifos-oxon (CPO), the metabolically-activated form of CPF. These observations suggest that HRW intake can protect rats from CPF-induced neurotoxicity, and the protective effects of hydrogen may be mediated by regulating the oxidant and antioxidant status of rats. Furthermore, this work defines a novel mechanism of biological activity of hydrogen by directly increasing the AChE activity. - Highlights: • Hydrogen molecules protect rats from CPF-induced damage of hippocampal neurons. • The increased GFAP expression induced by CPF can also be ameliorated by hydrogen. • Hydrogen molecules attenuated the increase in CPF-induced oxidative stress. • Hydrogen molecules attenuated AChE inhibition in vivo

    Full Text Available Endoscopic radial artery harvesting (ERAH is a feasible and attractive minimally invasive approach for conduit procurement, however there have been concerns about a potential neurological damage occurring at the harvest limb site secondary to injury of the radial nerve during endoscopic harvesting. We present a case of ERAH in which we evaluated intraoperatively the characteristics of radial nerve conduction by means of electroneuromyography (ENM during harvesting. No pathological changes of nerve conduction were detected at the harvest limb site during surgery and postoperatively, thereby supporting the benefits of the endoscopic approach in terms of neurological outcomes following radial artery procurements with a less invasive approach.

  4. The early struggles of the fledgling American Academy of Neurology: resistance from the old guard of American neurology.

    The American Neurological Association, established in 1874, was a small exclusive society comprising senior neurologists at a select number of north-eastern academic institutions. In 1948, an attempt was made to establish a second neurological society in the USA. The American Academy of Neurology was formed around a group of young neurologists who represented the country's Midwest and other regions. The American Academy of Neurology is now the larger of the two organizations, even though the American Academy of Neurology began as a small and politically vulnerable organization, arising in the shadow of the powerful and established American Neurological Association. How did the 75-year-old association react when a second, seemingly redundant, neurological association attempted to organize? This question has not been the focus of historical work, and the purpose of this study was to address this. To do so, the author studied the primary source materials in the American Academy of Neurology Historical Collection and the papers of Dr Henry Alsop Riley, an American neurologist, who was influential in both the American Neurological Association and American Academy of Neurology. On its formation, the American Academy of Neurology did not enter a vacuum. Indeed, the long-existing American Neurological Association actively resisted the new organization. There was reluctance to accept the new idea on a conceptual level, a formal attempt to hijack the new organization and discussions about punitive actions against its founder, while at the same time an attempt to bring him into the American Neurological Association leadership. Although the American Neurological Association attempted to frame itself as the patrician 'upper chamber' of American neurology, the American Academy of Neurology leadership was ultimately savvier at political manoeuvring and use of government agencies and funding organizations.

    AIM: To determine risk factors for early neurologic complications (NCs) after liver transplantation from perspective of recipient, donor, and surgeon. METHODS: In all, 295 adult recipients were enrolled consecutively between August 2001 and February 2014 from a single medical center in Taiwan. Any NC in the first 30 d post-liver transplantation, and perioperative variables from multiple perspectives were collected and analyzed. The main outcome was a 30-d NC. Generalized additive models were used to detect the non-linear effect of continuous variables on outcome, and to determine cut-off values for categorizing risk. Risk factors were identified using multiple logistic regression analysis. RESULTS: In all, 288 recipients were included, of whom 142 (49.3%) experienced at least one NC, with encephalopathy being the most common 106 (73%). NCs prolonged hospital stay (35.15 ± 43.80 d vs 20.88 ± 13.58 d, P 27.6 kg/m2, Child-Pugh class C, history of preoperative hepatoencephalopathy or mental disorders, day 7 tacrolimus level > 8.9 ng/mL, and postoperative intra-abdominal infection were more likely associated with NCs. Novel risk factors for NCs were donor age < 22 or ≥ 40 years, male-to-male gender matching, graft-recipient weight ratio 0.9%-1.9%, and sequence of transplantation between 31 and 174. CONCLUSION: NCs post- liver transplantation occurs because of factors related to recipient, donor, and surgeon. Our results provide a basis of risk stratification for surgeon to minimize neurotoxic factors during transplantation. PMID:27350733

  6. Perspectives for computational modeling of cell replacement for neurological disorders

    James B Aimone

    2013-11-01

    Full Text Available Mathematical modeling of anatomically-constrained neural networks has provided significant insights regarding the response of networks to neurological disorders or injury. A logical extension of these models is to incorporate treatment regimens to investigate network responses to intervention. The addition of nascent neurons from stem cell precursors into damaged or diseased tissue has been used as a successful therapeutic tool in recent decades. Interestingly, models have been developed to examine the incorporation of new neurons into intact adult structures, particularly the dentate granule neurons of the hippocampus. These studies suggest that the unique properties of maturing neurons can impact circuit behavior in unanticipated ways. In this perspective, we review the current status of models used to examine damaged CNS structures with particular focus on cortical damage due to stroke. Secondly, we suggest that computational modeling of cell replacement therapies can be made feasible by implementing approaches taken by current models of adult neurogenesis. The development of these models is critical for generating hypotheses regarding transplant therapies and improving outcomes by tailoring transplants to desired effects.

    Autoantibodies to glutamic acid decarboxylase (Gad-Abs) are implicated in various neurological syndromes. The present study aims to identify intrathecal-specific GAD-Abs and to determine clinical manifestations and treatment outcomes. Nineteen patients had GAD-Abs in cerebrospinal fluid but not in paired serum samples. Neurological syndromes included limbic encephalitis, temporal lobe epilepsy, cerebellar ataxia, autonomic dysfunction, and stiff-person syndrome. Immunotherapy had beneficial effects in 57.1% of patients, and the patients with limbic encephalitis responded especially well to immunotherapy. Intrathecal-specific antibodies to GAD at low titers may appear as nonspecific markers of immune activation within the central nervous system rather than pathogenic antibodies causing neuronal dysfunction.

    Full Text Available The U.S. national out-of-hospital and in-hospital cardiac arrest survival rates, although improving recently, have remained suboptimal despite the collective efforts of individuals, communities, and professional societies. Only until very recently, and still with inconsistency, has focus been placed specifically on survival with pre-arrest neurologic function. The reality of current approaches to sudden cardiac arrest is that they are often lacking an integrative, multi-disciplinary approach, and without deserved funding and outcome analysis. In this manuscript, a multidisciplinary group of authors propose practice, process, technology, and policy initiatives to improve cardiac arrest survival with a focus on neurologic function.

    2010-01-01

    Full Text Available Curcumin, the principal curcuminoid found in spice turmeric, has recently been studied for its active role in the treatment of various central nervous system disorders. Curcumin demonstrates neuroprotective action in Alzheimer′s disease, tardive dyskinesia, major depression, epilepsy, and other related neurodegenerative and neuropsychiatric disorders. The mechanism of its neuroprotective action is not completely understood. However, it has been hypothesized to act majorly through its anti-inflammatory and antioxidant properties. Also, it is a potent inhibitor of reactive astrocyte expression and thus prevents cell death. Curcumin also modulates various neurotransmitter levels in the brain. The present review attempts to discuss some of the potential protective role of curcumin in animal models of major depression, tardive dyskinesia and diabetic neuropathy. These studies call for well planned clinical studies on curcumin for its potential use in neurological disorders.

Severe hypernatremia is usually associated with central nervous system manifestations and carries a high mortality rate. We report a case of a female patient who presented to the emergency department of the King Khalid University Hospital, Riyadh, Saudi Arabia with severe hypernatremia and without any associated co-morbid conditions or neurological manifestations. We did not find any etiological background despite extensive eva-luation other than under hydration due to decreased fluid intake, which was secondary to beha-vioural causes.

    2015-07-01

    Full Text Available Ginseng (Order: Apiales, Family: Araliaceae, Genus: Panax has been used as a traditional herbal medicine for over 2000 years, and is recorded to have antianxiety, antidepressant and cognition enhancing properties. The protective effect of ginseng on neurological disorders is discussed in this review. Ginseng species and ginsenosides, and their intestinal metabolism and bioavailability are briefly introduced. This is followed by molecular mechanisms of effects of ginseng on the brain, including glutamatergic transmission, monoamine transmission, estrogen signaling, nitric oxide production, the Keap1/Nrf2 adaptive cellular stress pathway, neuronal survival, apoptosis, neural stem cells and neuroregeneration, microglia, astrocytes, oligodendrocytes and cerebral microvessels. The molecular mechanisms of the neuroprotective effects of ginseng in Alzheimer’s disease including Aβ formation, tau hyperphosphorylation and oxidative stress, major depression, stroke, Parkinson’s disease and multiple sclerosis / experimental allergic encephalitis are then presented. It is hoped that this discussion will stimulate more studies on the use of ginseng in these disorders.

    Exposure to microgravity and space travel produce several neurologic changes, including SAS, ataxia, postural disturbances, perceptual illusions, neuromuscular weakness, and fatigue. Inflight SAS, perceptual illusions, and ocular changes are of more importance. After landing, however, ataxia, perceptual illusions, neuromuscular weakness, and fatigue play greater roles in astronaut health and readaptation to a terrestrial environment. Cardiovascular adjustments to microgravity, bone demineralization, and possible decompression sickness and excessive radiation exposure contribute further to medical problems of astronauts in space. A better understanding of the mechanisms by which microgravity adversely affects the nervous system and more effective treatments will provide healthier, happier, and longer stays in space on the space station Freedom and during the mission to Mars.

  13. Zinc Deficiency in Humans and its Amelioration

    Full Text Available Zinc (Zn deficiency in humans has recently received considerable attention. Global mortality in children under 5 years of age in 2004 due to Zn deficiency was estimated at 4,53,207 as against 6,66,771 for vitamin A deficiency; 20,854 for iron deficiency and 3,619 for iodine deficiency. In humans 2800-3000 proteins contain Zn prosthetic group and Zn is an integral component of zinc finger prints that regulate DNA transcription. Zinc is a Type-2 nutrient, which means that its concentration in blood does not decrease in proportion of the Zn deficiency. Adverse effects of Zn deficiency vary with age: low weight gain, diarrhoea, aneroxia and neurobehavioral disturbances are observed in infants, while skin changes and dwarfism are frequent in toddlers and adolescents. Common manifestations of Zn deficiency among elderly include hypogeusia, chronic non-healing ulcers and recurrent infections.Ameliorative measures of Zn deficiency in humans can be classified in two groups, namely, nutraceutical and biofortification of food grains. Nutraceutical interventions include pharmaceutical supplements, dietary supplements and dietary diversification, while biofortification of food grains can be achieved by genetic modification (GM of crops or by agronomic techniques that include soil or/and foliar fertilization of crops.The major disadvantage of nutraceutical approaches is that the major beneficiaries are urban people and the poor rural masses that need adequate Zn nutrition most are left out. Genetic biofortification of food grains requires large amounts of funds and a fairly long-period of time. Further, a large number of countries have not yet accepted genetically modified (GM foods. On the other hand agronomic biofortification of food grains yields immediate effects and rural and urban people are equally benefitted. Our studies have shown that Zn concentration in cereals (rice, wheat etc and pulses can be considerably increased by soil or/and foliar

    2015-01-01

    Diseases of the brain are generally classified as either neurological or psychiatric. However, these two groups of illnesses cannot be readily separated on the basis of pathophysiology or symptomatology. It is difficult to rationally explain to someone with no prior frame of reference why we have the split between neurological and psychiatric illness. This demonstrates that the division is untenable, which has implications for training in both psychiatry and neurology.

    We report the repeated improvement in neurological function following naloxone administration in a patient who developed acute hemiplegia after an intracranial neurological procedure. The mechanisms responsible for the neurological deficit and for its reversal by naloxone are discussed. A review of the literature suggests that the beneficial effect of naloxone can result from an improvement in haemodynamic status or from metabolic effects that could be favorable during cerebral ischaemia.

    Remote limb preconditioning (RPC) ameliorates ischemia-induced cerebral infarction and promotes neurological function recovery; however, the mechanism of RPC hasn't been fully understood, which limits its clinical application. The present study aimed at exploring the underlying mechanism of RPC through testing its effects on neuronal oxidative DNA damage and parthanatos in a rat focal cerebral ischemia model. Infarct volume was investigated by 2, 3, 5-triphenyltetrazolium chloride (TTC) staining, and neuronal survival was evaluated by Nissl staining. Oxidative DNA damage was investigated via analyzing the expression of 8-hydroxy-2'-deoxyguanosine (8-OHdG). Besides, terminal deoxynucleotidyl transferase-mediated biotinylated-dUTP nick-end labeling (TUNEL) and DNA laddering were utilized to evaluate neuronal DNA fragmentation. Moreover, we tested whether RPC regulated poly(ADP-ribose) polymer (PAR) and apoptosis inducing factor (AIF) pathway; thus, PAR expression, AIF translocation and AIF/histone H2AX (H2AX) interaction were investigated. The results showed that RPC exerted neuroprotective effects by ameliorating oxidative DNA damage and neuronal parthanatos; additionally, RPC suppressed PAR/AIF pathway through reducing AIF translocation and AIF/H2AX interaction. The present study further exposed neuroprotective mechanism of RPC, and provided new evidence for the research on RPC and ICS. PMID:27288768

  1. Helicobacter pylori and neurological diseases: Married by the laws of inflammation

    Lourdes; álvarez-Arellano; Carmen; Maldonado-Bernal

    2014-01-01

    The purpose of this paper is to review current infor-mation about the role of inflammation caused by He-licobacter pylori(H. pylori) infection in neurological diseases such as Parkinson’s disease, Alzheimer’s dis-ease, Guillain-Barré syndrome, multiple sclerosis, and other inflammatory diseases including ischemic stroke. Infection with H. pylori usually persists throughout life, resulting in a chronic inflammatory response with local secretion of numerous inflammatory mediators includ-ing chemokines [interleukin(IL)-8, macrophage che-motactic protein, growth-regulated oncogene(GRO)-α, chemokine(C-X-C motif) ligand 1] and cytokines [IL-1β, tumor necrosis factor-α, IL-6, IL-12, interferon-g], which can pass into the circulation and have a systemic effect. The persistence of detectable systemic and lo-cal concentrations of inflammatory mediators is likely to alter the outcome of neurological diseases. These proinflammatory factors can induce brain inflammation and the death of neurons and could eventually be asso-ciated to Parkinson’s disease and also may be involved in the development of Alzheimer’s disease. However,most neurological diseases are the result of a combina-tion of multiple factors, but the systemic inflammatory response is a common component and determinant in the onset, evolution, and outcome of diseases. How-ever, more studies are needed to allow understanding of the effects and mechanisms by which the inflamma-tory response generated by H. pylori infection affects neurological diseases.

    2011-01-01

    OBJECTIVE: To summarize Cochrane reviews of acupuncture for neurological disorders, and characteristics of included reviews and studies.DATA SOURCES: A computer-based online search of the Cochrane Library (Issue 7 of 12, July 2010) was performed with the key word "acupuncture" and systematic evaluations for acupuncture for neurological disorders were screened.STUDY SELECTION: Systematic reviews on acupuncture in the treatment of neurological disorders were included, and the characteristics of these reviews were analyzed based on methods recommended by the Cochrane collaboration.MAIN OUTCOME MEASURES: Basic characteristics, methodological quality, main reasons for excluding trials, results and conclusions of Cochrane reviews were assessed.RESULTS: A total of 18 Cochrane systematic reviews were included, including 13 completed reviews and five research protocols. The 13 completed reviews involved 111 randomized controlled trials, including 43 trials (38.7%) conducted in China, 47 trials (42.3%) using sham-acupuncture or placebo as control, 15 trials (13.5%) with relatively high quality, 91 trials (81.9%) reporting data on follow-up. Primary outcomes used in the Cochrane reviews were reported by 65 trials (58.6%), and adverse events were reported in 11 trials (9.9%). Two hundred and eighty three trials were excluded. Two reviews on headache suggested that acupuncture is a valuable non-drug treatment for patients with chronic or recurrent headache, and has better curative effects on migraine compared with preventative drug treatment. CONCLUSION: Of the Cochrane reviews on acupuncture in the treatment of neurological disorders, two reviews evaluating the efficacy of acupuncture in treating headaches drew positive conculsions, while other reviews did not obtain positive conclusions due to a small sample size or low methodological quality. The methodological quality of acupuncture trials needs further improvement.

  3. Urgencias neurológicas y guardias de Neurología The problem of neurological emergencies and the need for specific neurology shifts

    2008-01-01

    Full Text Available En los últimos años distintos estudios han puesto de manifiesto un progresivo incremento en la demanda de atención neurológica en los servicios de urgencia. Para analizar la conveniencia de las guardias específicas de neurología o del papel que debe desempeñar el neurólogo en los servicios de urgencia, es preciso plantearse cuestiones como: ¿cuál es la demanda de atención neurológica urgente?, ¿cuáles son las urgencias neurológicas más frecuentes?, ¿quién debe atender las urgencias neurológicas y por qué?, ¿son necesarias las guardias específicas de neurología? Las urgencias neurológicas se sitúan entre el 2,6% y el 14% de las urgencias médicas. Los ictus representan la tercera parte de todas las urgencias neurológicas, mientras que los diagnósticos de enfermedad cerebrovascular aguda, epilepsia y cefalea constituyen el 50% de toda la atención neurológica en los servicios de urgencias. En base a criterios de calidad asistencial y de competencia profesional, la mejor atención del paciente con una urgencia neurológica la proporciona el especialista en neurología. La implantación de guardias específicas de neurología de presencia física durante 24 horas se asocia a una mayor calidad asistencial, mejora la orientación diagnóstica y terapéutica desde que el paciente llega a urgencias, reduce ingresos innecesarios, disminuye el coste de la asistencia neurológica, y potencia el servicio de Neurología.In recent years different studies have highlighted a progressive increase in the demand for neurological care in emergency departments. To analyze the convenience of specific neurology shifts or the role that the neurologist should play in the emergency department, it is necessary to answer questions such as: What is the demand for emergency neurological care? What are the most frequent neurological emergencies? Who should attend to neurological emergencies and why? Are specific neurology shifts necessary

    2016-08-01

    Sleep disorders are common in neurology practice, but are often undiagnosed and untreated. Specific patient cohorts, such as older adults, patients residing in nursing homes, and patients with underlying chronic neurologic and psychiatric disorders, are at particular risk. If these sleep problems are not properly evaluated and managed the patient may experience exacerbation of the underlying neurologic disorder. This article highlights some of the key sleep disorders relevant to practicing neurologists, emphasizing hypersomnolence, insomnia, and sleep-related movement disorders in the setting of neurologic disorders to enhance the tools available for evaluation, and discusses management strategies.

    Full Text Available A 2-month-old infant presented to our emergency department with fever, altered consciousness, and focal seizures of acute onset. He had vesicular skin lesions over the right preauricular region. CT brain showed a large hypodense lesion involving the left temporo-parietal region, left basal ganglia and left thalamus. MRI brain revealed bilateral multifocal corticomedullary lesions suggestive of encephalitis. CSF-PCR was positive for herpes simplex virus (HSV type I. He was treated with standard dose intravenous acyclovir for 15 days along with a trial of pulse methylprednisolone, but was readmitted within a week with features of an early relapse. The infant survived but developed significant neurological sequelae. Although treatment of HSV is available, the neurological outcome is guarded even with adequate antiviral therapy. Adjunct corticosteroid therapy did not appear to attenuate the neurological sequelae.

    2012-10-01

    Our aim was to investigate the correlations between head circumference (HC) growth and neurological impairment in microcephalic patients.HC charts of 3,269 patients from a tertiary pediatric neurology section were reviewed and 136 microcephalic participants were selected. Standardized HC Minimum, HC Drop, and HC Catch-up variables were defined. Children with evidence of significant learning disability and/or significant cerebral palsy were classified within the neurologically impaired group and the rest of participants within the normal group.Using discriminant analysis, we found that HC Minimum and HC Drop were relevant markers of neurological impairment. A positive HC Catch-up was significantly linked to a better outcome although this variable did not add significant information to HC Minimum and HC Drop. A Fisher linear discrimination cutoff function (C-function) was obtained as C = HC Minimum + HC Drop with a cutoff level of C = -4.28 standard deviations (SD).In our cohort, the addition of the lowest HC z-score to the preceding HC z-score drop was below -4.28 SD in 6 out of 10 neurologically impaired patients , whereas in the normal group, the result was over -4.28 SD in 9 out of 10 participants.

    Long-term exercise prior to brain ischemia enhances the activities of antioxidant enzymes and leads to a significant reduction in brain damage and neurological deficits in rats subjected to transient middle cerebral artery occlusion. However, it has not been established whether relatively short-term exercise generates similar results following middle cerebral artery occlusion. We aimed to determine whether short-term exercise could reduce oxidative damage and prevent sensori-motor dysfunction. Male Wistar rats were subjected to perform daily exercise on a treadmill for 30 min at a speed of 15 m/min for 3 weeks, followed by a 90-min middle cerebral artery occlusion. Animals were assessed after middle cerebral artery occlusion for neurological deficits and sensori-motor function. Brain tissues were processed to evaluate infarct volume and oxidative damage. Oxidative stress was assessed using immunohistochemistry for 4-hydroxy-2-nonenal-modified proteins and 8-hydroxy-2'-deoxyguanosine. Antioxidant enzymes were evaluated using immunohistochemistry for thioredoxin and activity assay for superoxide dismutase. Exercise for 3 weeks decreased the severity of paralysis and impairment in forelimb motor coordination. Furthermore, exercise had effect on superoxide dismutase and reduced the infarct volume and the number of cells immunopositive for 4-hydroxy-2-nonenal-modified proteins and 8-hydroxy-2'-deoxyguanosine. Our results suggest that pre-conditioning treadmill exercise for 3 weeks is useful for ameliorating ischemia-induced brain injury. PMID:23874064

    Statins could have physiologic properties that may beneift patients that have been diagnosed with various acute neurological diseases. This review aims tosummarize the literature pertaining to stain use in acute neurological disease such as subarachnoid hemorrhage, intracerebral hemorrhage (ICH), cerebral ischemia (CI), traumatic brain injury, status epilepticus and meningitis. The authors reviewed published abstracts and manuscripts pertaining to experimental and clinical trials relevant to statins in acute neurological disease. Although acute statin therapy in the setting of subarachnoid hemorrhage might reduce delayed cerebral ischemia and mortality, it should not be considered standard care at this time. Acute statins therapy has not demonstrated anybeneift yet folowing an ICH or CI. Acute statin withdrawal may worsen outcome in acute CI. Observational and case-control studies suggest that pretreatment with statin at time of onset may be associated with better outcomes. Even though preclinical studies have shown statins to have beneifcial effects, there has been no clinical evidence. In conclusion, current published studies have not shown that acute statin therapy has any beneifcal effects in acute neurologic diseases and therefore further large randomized clinical trials are needed.

  18. Ketogenic diets, mitochondria, and neurological diseases.

    Gano, Lindsey B; Patel, Manisha; Rho, Jong M

    2014-11-01

    The ketogenic diet (KD) is a broad-spectrum therapy for medically intractable epilepsy and is receiving growing attention as a potential treatment for neurological disorders arising in part from bioenergetic dysregulation. The high-fat/low-carbohydrate "classic KD", as well as dietary variations such as the medium-chain triglyceride diet, the modified Atkins diet, the low-glycemic index treatment, and caloric restriction, enhance cellular metabolic and mitochondrial function. Hence, the broad neuroprotective properties of such therapies may stem from improved cellular metabolism. Data from clinical and preclinical studies indicate that these diets restrict glycolysis and increase fatty acid oxidation, actions which result in ketosis, replenishment of the TCA cycle (i.e., anaplerosis), restoration of neurotransmitter and ion channel function, and enhanced mitochondrial respiration. Further, there is mounting evidence that the KD and its variants can impact key signaling pathways that evolved to sense the energetic state of the cell, and that help maintain cellular homeostasis. These pathways, which include PPARs, AMP-activated kinase, mammalian target of rapamycin, and the sirtuins, have all been recently implicated in the neuroprotective effects of the KD. Further research in this area may lead to future therapeutic strategies aimed at mimicking the pleiotropic neuroprotective effects of the KD. PMID:24847102

    Children with neurological impairment (NI) frequently require feeding gastrostomy, and this often aggravates or produces gastroesophageal reflux (GER). From 1976 to 1994, 141 children with severe NI underwent Thal fundoplication and gastrostomy (GT). GER was evident in 80%; in the rest, fundoplication was an adjunct to GT. Ph results were positive in 38 cases, and 57 children had reflux according to the barium studies. There were no major intraoperative complications. Disruption of the repair and/or recurrent GER was noted in 14 cases (10%); 8 were redone as Thals, and 6 were converted to Nissen procedures. Pyloroplasty was done later in 9 children (6%). Bowel obstruction was seen in 4 patients (3%). Clinical follow-up (mean, 54 months) showed improvement in 96%; only 5 of the 141 (3.2%) have residual symptoms. Of the patients with an intact Thal, 67% could burp or vomit. The ability to vomit may protect the Thal fundoplication and avoid disruption of the repair. PMID:8783112

    Full Text Available Congenital hip luxation is a disorder which evolves in time. Teratological hip dislocation is a distinct form of hip luxation, which usually appears with other disorders. These hips are dislocated before birth. In this thesis we will try to elaborate a recovery program, through physical exercises, which will help us realize our treatment objectives: diminishing articular stiffness, increasing articular mobility, increasing muscle strength, recalibration of agonist and antagonist balances and reeducating gait. The specific objectives of the study consist of the particularization of the recovery programs based on age, illness stage (dysplasia or luxation and either surgical or non-surgical intervention. To show the importance of physiotherapy in gait rehabilitation of a child with hip dislocation we started from the hypothesis: using an adequate rehabilitation program after an individualized methodology, optimizes the functional recovery and ensures the gains of hip stability and the formation of an engram of gait as close as it could be to the normal one. We present a case of neurological congenital hip dislocation where the treatment initiated early is showing good results. Results obtained are significantly different and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient has better biomechanical results for the hip.

    This mini-review focus on our studies on alterations in glutamatergic neurotransmission and their role in neurological alterations in rat models of chronic hyperammonemia and hepatic encephalopathy (HE). Hyperammonemia impairs the glutamate-nitric oxide (NO)-cGMP pathway in cerebellum, which is responsible for reduced learning ability. We studied the underlying mechanisms and designed treatments to restore the pathway and learning. This was achieved by treatment with: phosphodiesterase 5 inhibitors, cGMP, anti-inflammatories (ibuprofen), p38 inhibitors or GABAA receptor antagonists (bicuculline). Hyperammonemia alters signal transduction associated to metabotropic glutamate receptors (mGluRs). Hypokinesia in hyperammonemia and HE is due to increased extracellular glutamate and mGluR1 activation in substantia nigra; blocking this receptor restores motor activity. The motor responses to mGluRs activation in nucleus accumbens (NAcc) are altered in hyperammonemia and HE, with reduced dopamine and increased glutamate release. This leads to activation of different neuronal circuits and enhanced motor responses. These studies show that altered responses to activation of NMDA receptors and mGluRs play essential roles in cognitive and motor alterations in hyperammonemia and HE and provide new treatments restoring cognitive and motor function.

    Full Text Available The data on the current vaccination process and specific antibody in 212 children with pathology of nervous systems in age from 1 year to 6 years old, vaccinated against measles. The comparison group consisted of 36 children without neurological disease. 86 children (40,6% were vaccinated measles – mumps vaccine, and 126 children (59,4% only measles vaccine. Post-vaccination period in 77,8% immunized against measles, was uneventful, layering intercurrent infections was noted in 22,2% of vaccine’s, and demonstrated the development of viral respiratory infections, bronchitis, otitis media and exacerbation of underlying disease. It is shown that the level of specific antibody to measles in children with pathology of nervous systems at 30 days after vaccination was 5,04±0,16 log 2, which did not differ from the comparison group (5,88±0,31 log 2. No significant differences in the level of antibody in a smooth and complicated course of vaccination period were found. Immunization of children with disorders of the nervous system of live vaccines is quite effective and leads to the formation of protective antibody titers in all vaccinated.

    The idea of a conflict between demonology and psychiatry has been a foundational myth in the history of medicine. Nineteenth-century alienists such as J.-M. Charcot and Henry Maudsley developed critiques of supernatural phenomena in an attempt to pathologize religious experience. Modern historians have reanalyzed these critiques, representing them as strategies in medical professionalization. These accounts all maintain an oddly bifurcated approach to the perceived conflict, treating demonology, as a passive and unchanging set of practices, while medicine is depicted as an active and aggressive agent. An examination of early twentieth-century demonological literature reveals a very different story. Fundamentalists and Pentecostalists engaged with the problems of conversion and possession, developing sophisticated models of the normal and the pathological in spiritual experience. Their writings drew upon medical and psychiatric sources ranging widely from Pastorian germ theory to Jacksonian neurology. This article explores the points of contact between the medical and demonological communities in order to demonstrate the contested nature of biomedical innovation. PMID:15161086

    Cerebral desaturation can occur during surgery manipulation, whereas other parameters vary insignificantly. Prolonged intervals of cerebral anoxia can cause serious damage to the nervous system. Commonly used method for measurement of cerebral blood flow uses invasive catheters. Other techniques include single photon emission computed tomography (SPECT), positron emission tomography (PET), magnetic resonance imaging (MRI). Tomographic methods frequently use isotope administration, that may result in anaphylactic reactions to contrast media and associated nerve diseases. Moreover, the high cost and the need for continuous monitoring make it difficult to apply these techniques in clinical practice. Cerebral oximetry is a method for measuring oxygen saturation using infrared spectrometry. Moreover reflection pulse oximetry can detect sudden changes in sympathetic tone. For this purpose the reflectance pulse oximeter for use in neurology is developed. Reflectance oximeter has a definite advantage as it can be used to measure oxygen saturation in any part of the body. Preliminary results indicate that the device has a good resolution and high reliability. Modern applied schematics have improved device characteristics compared with existing ones.

    Speech correlates of alcohol/drug impairment and its neurological basis is presented with suggestion for further research in impairment from poly drug/medicine/inhalent/chew use/abuse, and prediagnosis of many neuro- and endocrin-related disorders. Nerve cells all over the body detect chemical entry by smoking, injection, drinking, chewing, or skin absorption, and transmit neurosignals to their corresponding cerebral subsystems, which in turn affect speech centers-Broca's and Wernick's area, and motor cortex. For instance, gustatory cells in the mouth, cranial and spinal nerve cells in the skin, and cilia/olfactory neurons in the nose are the intake sensing nerve cells. Alcohol depression, and brain cell damage were detected from telephone speech using IMPAIRLYZER-TM, and the results of these studies were presented at 1996 ASA meeting in Indianapolis, and 2001 German Acoustical Society-DEGA conference in Hamburg, Germany respectively. Speech based chemical Impairment measure results were presented at the 2001 meeting of ASA in Chicago. New data on neurotolerance based chemical impairment for alcohol, drugs, and medicine shall be presented, and shown not to fully support NIDA-SAMSHA drug and alcohol threshold used in drug testing domain.

  15. Practical considerations on the use of rituximab in autoimmune neurological disorders

    Science.gov (United States)

    Kosmidis, Mixalis L.; Dalakas, Marinos C.

    2010-01-01

    Rituximab (Mabthera, Rituxan) is a chimeric human/murine monoclonal antibody against CD-20 surface antigen expressed on B-cells. Rituximab, by causing B-cell depletion, appears to be effective in several autoimmune disorders; it has been approved for rheumatoid arthritis and is a promising new agent in the treatment of several autoimmune neurological disorders. A controlled study in patients with relapsing remitting multiple sclerosis has shown that rituximab significantly reduces the number of new MRI lesions and improves clinical outcome; it also showed some promise in a subset of patients with primary progressive MS. The drug is also effective in a number of patients with Devic’s disease, myasthenia gravis, autoimmune neuropathies, and inflammatory myopathies. The apparent effectiveness of rituximab has moved B-cells into the center stage of clinical and laboratory investigation of autoimmune neurological disorders. We review the evidence-based effectiveness of rituximab in neurological disorders based on controlled trials and anecdotal reports, including our own experience, and address the immunobiology of B-cells in autoimmune central nervous system (CNS) and peripheral nervous system (PNS) disorders. In addition, we provide practical guidelines on how best to use this drug in clinical practice and highlight its potential toxicity. PMID:21179602

    In spite of the increasing number of studies on insight in psychiatry and also in neurology and psychology, its nature is still elusive. It encompasses at least three fundamental characteristics: the awareness of suffering from an illness, an understanding of the cause and source of this suffering, and an acknowledgment of the need for treatment. As such, insight is fundamental for patients' management, prognosis, and treatment. Not surprisingly, the majority of available data, which have been gathered on schizophrenia, show a relationship between low insight and poorer outcomes. For mood disorders, however, insight is associated with less positive results. For other psychiatric disorders, insight has rarely been investigated. In neurology, the impaired ability to recognize the presence of sensory, perceptual, motor, affective, or cognitive functioning-referred to as anosognosia-has been related to damage of specific brain regions. This article provides a comprehensive review of insight in different psychiatric and neurological disorders, with a special focus on brain areas and neurotransmitters that serve as the substrate for this complex phenomenon.

    Full Text Available OBJECTIVES: This study was undertaken to characterize the neuroinfection profile in a tertiary neurological ward. INTRODUCTION: Neuroinfection is a worldwide concern and bacterial meningitis, tetanus and cerebral malaria have been reported as the commonest causes in developing countries. METHODS: From 1999 to 2007, all patients admitted to the Neurology Ward of Hospital das Clínicas, São Paulo University School of Medicine because of neuroinfection had their medical records reviewed. Age, gender, immunological status, neurological syndrome at presentation, infectious agent and clinical outcome were recorded. RESULTS: Three hundred and seventy four cases of neuroinfectious diseases accounted for 4.2% of ward admissions and the identification of infectious agent was successful in 81% of cases. Mean age was 40.5 + 13.4 years, 63.8% were male, 19.7% were immunocompromised patients and meningoencephalitis was the most common clinical presentation despite infectious agent. Viruses and bacteria were equally responsible for 29.4% of neuroinfectious diseases; parasitic, fungal and prion infections accounted for 28%, 9.6% and 3.5% respectively. Human immunodeficiency virus (HIV, herpes simplex virus 1 (HSV1, Mycobacterium tuberculosis, Treponema pallidum, Taenia solium, Schistosoma mansoni, Cryptococcus neoformans and Histoplasma capsulatum were the more common infectious pathogens in the patients. Infection mortality rate was 14.2%, of which 62.3% occurred in immunocompetent patients. CONCLUSION: Our institution appeared to share some results with developed and developing countries. Comparison with literature may be considered as quality control to health assistance.

    Full Text Available French medicine was of the utmost importance for the birth of modern medicine and neurology in the 19 th century. Innovative approaches, such as examination at the bedside, the use of the stethoscope, techniques of auscultation, palpation, and close patient examination, besides emphasis on anatomical-clinical correlation and observation of the outcome of the disease, were put into practice. French medicine offered professional training and incentives for the beginnings of Brazilian neurology and psychiatry. Returning from France, many Brazilian physicians implemented what they had learned, mainly in Paris. The most important pupils of the French neurology schools in Brazil during the 19 th century and first half of the 20 th century include names like Antonio Austregesilo, Aloysio de Castro, Enjolras Vampré, and Deolindo Couto, founders of the leading Brazilian neurological schools, directly influenced by Dejerine, Pierre Marie, Guillain and Babinski.

    In the past century, noncommunicable diseases have surpassed infectious diseases as the principal cause of sickness and death, worldwide. Trillions of commensal microbes live in and on our body, and constitute the human microbiome. The vast majority of these microorganisms are maternally derived and live in the gut, where they perform functions essential to our health and survival, including: digesting food, activating certain drugs, producing short-chain fatty acids (which help to modulate gene expression by inhibiting the deacetylation of histone proteins), generating anti-inflammatory substances, and playing a fundamental role in the induction, training, and function of our immune system. Among the many roles the microbiome ultimately plays, it mitigates against untoward effects from our exposure to the environment by forming a biotic shield between us and the outside world. The importance of physical activity coupled with a balanced and healthy diet in the maintenance of our well-being has been recognized since antiquity. However, it is only recently that characterization of the host-microbiome intermetabolic and crosstalk pathways has come to the forefront in studying therapeutic design. As reviewed in this report, synthetic biology shows potential in developing microorganisms for correcting pathogenic dysbiosis (gut microbiota-host maladaptation), although this has yet to be proven. However, the development and use of small molecule drugs have a long and successful history in the clinic, with small molecule histone deacetylase inhibitors representing one relevant example already approved to treat cancer and other disorders. Moreover, preclinical research suggests that epigenetic treatment of neurological conditions holds significant promise. With the mouth being an extension of the digestive tract, it presents a readily accessible diagnostic site for the early detection of potential unhealthy pathogens resident in the gut. Taken together, the data outlined

    Neurologic complications after roller coaster rides are uncommon but potentially catastrophic. Physicians should have a high index of suspicion and prompt appropriate investigation. A 22-year-old healthy African American man presented with a 2-day history of constant occipital headache associated with vertigo, nausea, vomiting, and ambulatory dysfunction. Physical examination showed gait ataxia, slight dysmetria, and vertical nystagmus. Magnetic resonance imaging (MRI) of the brain showed early subacute ischemic infarct in the right cerebellum in the distribution of the right posterior inferior cerebellar artery. Magnetic resonance angiography of the neck showed focal dissection of the right vertebral artery at C1 through C2 level. On subsequent questioning, the patient recollected riding a roller coaster 2 weeks before the onset of symptoms. Anticoagulation with heparin was started, and the patient was bridged to oral warfarin. After a 5-day uneventful hospital course, symptoms improved and patient was discharged on oral anticoagulation. Cervicocephalic arterial dissections after roller coaster rides are rarely described in literature. The acceleration and abrupt changes of direction might lead to indirect trauma that is applied to mobile portions of the cervicocephalic arteries leading to intimal tears. Magnetic resonance angiography combined with axial T1-weighted cervical MRI is preferred because it is a high-sensitive, noninvasive test. The rationale for the use of anticoagulants or antiplatelets in patients with cervicocephalic arterial dissection is to prevent early recurrence and infarction. However, a meta-analysis failed to show significant difference in the rates of disability or death between both groups. Therefore, the decision for medical treatment should be made in a case-by-case basis. PMID:20980120

    Full Text Available The coexistence of neuronal degeneration, psychiatric manifestation, immune activation and malignant transformation has been documented in literature, suggesting a central dysfunction in the pathophysiology of these disorders. The isoprenoid pathway may be candidate in this respect, in view of the changes in the concentration of some products of this pathway in many of these disorders, however, no detailed study has been carried out in this respect. In view of this, a study was undertaken on the isoprenoid pathway in some of these disorders - primary generalized epilepsy, Parkinson’s disease (PD, schizophrenia, manic depressive psychosis (MDP, CNS glioma, multiple sclerosis, subacute sclerosing panencephalitis (SSPEand a familial group with familial coexistence of schizophrenia, PD, primary generalized epilepsy, malignant neoplasia, rheumatoid arthritis and syndrome-X over three generations. The following parameters were studied in the patients of these disorders as compared to age and sex matched control subjects - ubiquinone dolichol, digoxin, activity of HMG CoA reductase in the plasma and erthyorcyte membrane Na -K--ATpase. Increase in the activity of HMG CoA reductase and in the concentration of plasma digoxin and dolichol was observed in most of these cases. On the other hand, there was decrease in the concentration of plasma ubiquinone. Decrease in the activity of erythrocyte membrane Na-K- ATpase activity for which digoxin is an inhibitor was also observed in all the cases studied. These results indicate an upregulation of the isoprenoid pathway in the neurological and psychiatric disorders studied. The implications of this change is discussed in details.

    Full Text Available Abstract Background Malaria is a leading cause of ill health and neuro-disability in children in sub-Saharan Africa. Impaired cognition is a common outcome of malaria with neurological involvement. There is also a possibility that academic achievement may be affected by malaria with neurological involvement given the association between cognitive ability and academic achievement. This study investigated the effect of malaria with neurological involvement on cognitive ability, behaviour and academic achievement. Methods This prospective case-control study was carried out in Kampala City, Uganda between February 2008 and October 2010. Sixty-two children with a history of malaria with neurological involvement were followed up and given assessments for cognitive ability (working memory, reasoning, learning, visual spatial skills and attention, behaviour (internalizing and externalizing problems and academic achievement (arithmetic, spelling and reading three months after the illness. Sixty-one community controls recruited from the homes or neighbouring families of the cases were also given the same assessments. Tests scores of the two groups were compared using analysis of covariance with age, sex, level of education, nutritional status and quality of the home environment as covariates. This study was approved by the relevant ethical bodies and informed consent sought from the caregivers. Results Children in the malaria group had more behavioural problems than the community controls for internalizing problems (estimated mean difference = -3.71, 95% confidence interval (CI, = -6.34 to -1.08, p = 0.007. There was marginal evidence of lower attention scores (0.40, CI = -0.05 to 0.86, p = 0.09. However, excluding one child from the analyses who was unable to perform the tests affected the attention scores to borderline significance (0.32, CI, = 0.01 to 0.62, p = 0.05. No significant differences were observed in other cognitive abilities or in academic

    Objective To perform a systematic review of studies using remote physical activity monitoring in neurological diseases, highlighting advances and determining gaps. Methods Studies were systematically identified in PubMed/MEDLINE, CINAHL and SCOPUS from January 2004 to December 2014 that monitored physical activity for ≥24 hours in adults with neurological diseases. Studies that measured only involuntary motor activity (tremor, seizures), energy expenditure or sleep were excluded. Feasibility, findings, and protocols were examined. Results 137 studies met inclusion criteria in multiple sclerosis (MS) (61 studies); stroke (41); Parkinson's Disease (PD) (20); dementia (11); traumatic brain injury (2) and ataxia (1). Physical activity levels measured by remote monitoring are consistently low in people with MS, stroke and dementia, and patterns of physical activity are altered in PD. In MS, decreased ambulatory activity assessed via remote monitoring is associated with greater disability and lower quality of life. In stroke, remote measures of upper limb function and ambulation are associated with functional recovery following rehabilitation and goal-directed interventions. In PD, remote monitoring may help to predict falls. In dementia, remote physical activity measures correlate with disease severity and can detect wandering. Conclusions These studies show that remote physical activity monitoring is feasible in neurological diseases, including in people with moderate to severe neurological disability. Remote monitoring can be a psychometrically sound and responsive way to assess physical activity in neurological disease. Further research is needed to ensure these tools provide meaningful information in the context of specific neurological disorders and patterns of neurological disability. PMID:27124611

    Background Paraneoplastic neurologic syndromes (PNS) pose quite an uncommon neurological complication, affecting less than 1% of patients with breast cancer. Nearly one third of these patients lack detectable onconeural antibodies (ONAs), and improvement in neurologic deficits with concomitant cancer treatments is achieved in less than 30% of cases. Case Presentation A 42-year-old, premenopausal woman presented with facial paralysis on the central left side accompanied by a left tongue deviation, an upward vertical nystagmus, moderate spastic paraparesis, dystonic posturing of the left foot, lower limb hyperreflexia and bilateral extensor plantar reflex. After ruling out all other potential neurologic causes, PNS was suspected but no ONAs were found. A PET-CT scan detected increased metabolism in the right breast, as well as an ipsilateral thoracic interpectoral adenopathy. Core biopsy confirmed the presence of an infiltrating duct carcinoma. After breast surgery, the neurologic symptoms disappeared. One week later, the patient was readmitted to the hospital with a bilateral fatigable eyelid ptosis, and two weeks later, there was a noticeable improvement in eyelid ptosis, accompanied by a rapid and progressive development of lower spastic paraparesis. She started adjuvant treatment with chemotherapy with marked clinical and neurological improvement, and by the end of radiotherapy, there were no signs of neurologic impairment. Conclusion This case study highlights the importance of a high level of vigilance for the detection of PNS, even when ONAs are not detected, as the rapid identification and treatment of the underlying tumor offers the best chance for a full recovery.

    2014-07-01

    Full Text Available Allopregnanolone (Allo, a neurosteroid, has emerged as a promising promoter of endogenous regeneration in brain. In a mouse model of Alzheimer’s disease, Allo induced neurogenesis, oligodendrogenesis, white matter generation and cholesterol homeostasis while simultaneously reducing β-amyloid and neuroinflammatory burden. Allo activates signaling pathways and gene expression required for regeneration of neural stem cells and their differentiation into neurons. In parallel, Allo activates systems to sustain cholesterol homeostasis and reduce β-amyloid generation. To advance Allo into studies for chronic human neurological conditions, we examined translational and clinical parameters: dose, regimen, route, formulation, outcome measures, and safety regulations. A treatment regimen of once per week at sub-sedative doses of Allo was optimal for regeneration and reduction in Alzheimer’s pathology. This regimen had a high safety profile following chronic exposure in aged normal and Alzheimer’s mice. Formulation of Allo for multiple routes of administration has been developed for both preclinical and clinical testing. Preclinical evidence for therapeutic efficacy of Allo spans multiple neurological diseases including Alzheimer’s, Parkinson’s, multiple sclerosis, Niemann-Pick, diabetic neuropathy, status epilepticus, and traumatic brain injury. To successfully translate Allo as a therapeutic for multiple neurological disorders, it will be necessary to tailor dose and regimen to the targeted therapeutic mechanisms and disease etiology. Treatment paradigms conducted in accelerated disease models in young animals have a low probability of successful translation to chronic diseases in adult and aged humans. Gender, genetic risks, stage and burden of disease are critical determinants of efficacy. This review focuses on recent advances in development of Allo for Alzheimer’s disease that have the potential to accelerate therapeutic translation for

    Full Text Available Abstract Background Apgar score is used for rapid assessment of newborns. Low five-minute Apgar score has been associated with increased risk of severe neurologic outcome, but data on milder outcomes, particularly in the long term, are limited. We aimed to examine the association of five-minute Apgar score with prevalence of neurologic disability and with cognitive function in early adulthood. Methods We conducted a prevalence study among draft-liable men born in Denmark in 1978–1983 and presenting for the mandatory army evaluation in a northern Danish conscription district. We linked records of this evaluation, which includes medical exam and intelligence testing, with the conscripts' records in the Medical Birth Registry, containing perinatal data. We examined prevalence of neurologic disability and of low cognitive function according to five-minute Apgar score. Results Less than 1% (136/19,559 of the conscripts had 5-minute Apgar scores Conclusion A five-minute Apgar score

  8. Diagnostic imaging of acute neurologic symptoms in children

    International Nuclear Information System (INIS)

    The diagnostic imaging of children with acute, non-traumatic, neurologic symptoms enables a fast and non-invasive localization and diagnosis. A spectrum of typical disorders will be described dependent on the location of neurologic symptoms (central, spinal, or peripheral nervous system). Different non-invasive imaging modalities e.g. US with colour-coded doppler, CT, MRI are utilized dependent on age of the patient and neurologic symptoms. The purpose of this article is to describe the spectrum of diagnostic imaging for each of these common disorders. (orig.)

    Eclampsia is one of the most common acute neurological events occurring during pregnancy. However, there are many other conditions that can present during pregnancy and the puerperium and that may either mimic eclampsia or produce other acute neurological manifestations. Frequently the symptoms and signs are non-specific, and it can be difficult to differentiate between these conditions on clinical grounds alone. Neuroradiological studies can provide valuable diagnostic information, and interventional radiological procedures may play a part in the subsequent management of these conditions. This review focuses on the imaging of acute neurological conditions which may be associated with, or present during, pregnancy and the puerperium.

    Full Text Available OBJECTIVE : To study the neurological recovery pattern and clinical recovery after surgical intervention in patients of degenerative cervical myelopathy and radiculopathy to know the surgical outcome, at L okmanya T ilak M unicipal M edical C ollege , Mumbai, Maharashtra . METHOD : We ca rried out prospective and retrospective observational study of 30 patients with functional disability secondary to cervical degenerative myelopathy and radiculopathy who underwent surgery for decompression of the cervical spinal cord with or without spinal stabilization. March 2012 to March 2013 were studied and followed for more than 1year. All patients were operated by a single surgeon and reviewed independently. All the patients had received appropriate conservative management before undergoing surgical intervention . Data was analysed by using appropriate software. RESULTS : The study group comprised of 27 males and 3 females aged between 36 and 75 years with a mean age of 56 years that presented with functional disability secondary to cervical myelopathy and radiculopathy. Pain and neurological examination were used as criteria at sequential follow – ups. Functional outcome was assessed using Japanese Orthopaedic Association score, Oswestry Disability Index and Visual Analogue Scale. It was found that neuro logical recovery for myelopathy by mJOA score at intervals between 15 days to 3 months was significant after which recovery was occurring but was not significant. Anterior cervical discectomy with fusion for 1 - 2 levels has given good results than posterior laminectomy for 3 or more levels. Cervical radiculopathy alone has good recovery results after decompression surgery than myelopathy or myelopathy with radiculopathy. CONCLUSION: Based on this study, we found that the results of surgery for cervical spon dylotic myelopathy and radiculopathy are excellent. The best neurological and functional recovery is seen in patients with mild to moderate

    Contact sport holds inherent risk of traumatic injury to participant athletes. Neurologic injury, from trauma, portends significant potential for morbidity and mortality. The in-game sideline presents a challenging setting for injury evaluation. Athletic trainers and team physicians should understand general principles of the neurologic evaluation and apply a systematic approach that allows an organized evaluation of and differential diagnosis of neurologic injury. Athlete welfare demands an immediate, accurate diagnosis followed by targeted management. Management provides appropriate referral, timely treatment, and appropriate return-to-play decision. Management begins with recognition. PMID:27215629

    Neurological soft signs (NSS) were studied in some axis-I disorders like schizophrenia, obsessive compulsive disorder, bipolar disorder, alcohol and substance abuse disorder. Aim of this study is detection of neurological soft signs in antisocial personality disorder and relation of these signs with psychopathy. The study was included 41 antisocial men and 41 healthy control subjects. Sociodemographic form, neurological evaluation scale and Hare psychopathy checklist was applied to the antisocial subjects, whereas sociodemographic form and neurological evaluation scale were applied to the controls. Antisocial men exhibited significiantly more NSS in total score and subgroups scales (pantisocial group significantly more than controls in our study. Significant relationship between psychopathy and NSS may also hint the role of genetic mechanisms in personality development, though new extended studies with larger sample size are needed for clarification of this relationship.

    2014-02-01

    Stroke is the second leading cause of death in industrialized countries and the most frequent cause of permanent disability in adults worldwide. The final outcome of stroke is determined not only by the volume of the ischemic core, but also by the extent of secondary brain damage inflicted to penumbral tissues by brain swelling, impaired microcirculation, and inflammation. The only drug approved for the treatment ischemic stroke is recombinant tissue plasminogen activator (rt-PA). The current study was designed to investigate the protective effects of candesartan (0.15 mg/kg, orally) and glycyrrhizin (30 mg/kg, orally) experimentally-induced ischemic brain damage in C57BL/6 mice (middle cerebral artery occlusion, MCAO) in comparison to the effects of a standard neuroprotective drug (cerebrolysin, 7.5 mg/kg, IP). All drugs were administered 30 min before and 24h after MCAO. Both candesartan and glycyrrhizin ameliorated the deleterious effects of MCAO as indicated by the improvement in the performance of the animals in behaviour tests, reduction in brain infarction, neuronal degeneration, and leukocyte infiltration. In addition, MCAO induced a significant upregulation in the different elements of the TLR pathway including TLR-2 and TLR-4, Myd88, TRIF and IRF-3 and the downstream effectors TNF-α, IL-1β, IL-6 and NF-kB. All these changes were significantly ameliorated by treatment with candesartan and glycyrrhizin. The results of the current study represent a new indication for both candesartan and glycyrrhizin in the management of ischemic stroke with effects comparable to those of the standard neuroprotective drug cerebrolysin.

However, the high poverty level (54% relative and 35% extreme poverty makes it difficult for disadvantaged parents to pay the high fees charged by the centres. This study describes an attempt to economically empower mothers through the organisation of free early life education in a peri-urban community in Lagos.Objectives: The aim of the study was to examine early life education for under-fives as a means of economic empowerment of mothers and sustainable poverty amelioration. Method: The methodology included a non-randomised selection of 34 disadvantaged mothers by criteria, a prospective intervention utilising community resources to organise early childhood education, an in-depth interview of mothers, and observation of the outcomes over a 5-year period.Results: The result of the study showed that no mother preferred keeping a child older than three years at home. Access to early childhood education gave mothers opportunity to undergo vocational training (1, 2.8% and take up new/additional jobs (12, 35.3%. All mothers and 32 (80% of the participating families more than doubled their income, earning up to twenty thousand Naira (approximately $182 per month from the first year of participation. Finally, selection criteria and periodic assessment of immunisation/growth monitoring records of participants’ children improved compliance with primary health care service utilisation.Conclusion: Organisation of early childhood education had the potential for sustainable poverty amelioration through economic empowerment of mothers.

    There is accumulating evidence that peripheral motor axons deteriorate following spinal cord injury (SCI). Secondary axonal dysfunction can exacerbate muscle atrophy, contribute to peripheral neuropathies and neuropathic pain, and lead to further functional impairment. In an attempt to ameliorate the adverse downstream effects that developed following SCI, we investigated the effects of a short-term peripheral nerve stimulation (PNS) program on motor axonal excitability in 22 SCI patients. Axonal excitability studies were undertaken in the median and common peroneal nerves (CPN) bilaterally before and after a 6-wk unilateral PNS program. PNS was delivered percutaneously over the median nerve at the wrist and CPN around the fibular head, and the compound muscle action potential (CMAP) from the abductor pollicis brevis and tibialis anterior was recorded. Stimulus intensity was above motor threshold, and pulses (450 μs) were delivered at 100 Hz with a 2-s on/off cycle for 30 min 5 days/wk. SCI patients had consistently high thresholds with a reduced CMAP consistent with axonal loss; in some patients the peripheral nerves were completely inexcitable. Nerve excitability studies revealed profound changes in membrane potential, with a "fanned-in" appearance in threshold electrotonus, consistent with membrane depolarization, and significantly reduced superexcitability during the recovery cycle. These membrane dysfunctions were ameliorated after 6 wk of PNS, which produced a significant hyperpolarizing effect. The contralateral, nonstimulated nerves remained depolarized. Short-term PNS reversed axonal dysfunction following SCI, may provide an opportunity to prevent chronic changes in axonal and muscular function, and may improve rehabilitation outcomes.

    Neurofibromatosis type 1 (NF1) is a genetic disease with a wide range of neurological manifestations. To examine these, and to evaluate neurological morbidity in adulthood of patients with NF1, we studied a hospital-based series of 158 patients that included 138 adult patients aged >18 years and 20 children. NF1 evaluation included a multidisciplinary clinical and a clinically oriented radiological investigation. Neurological events occurring during childhood (in both children and adults of the series) and adulthood were recorded. One or several neurological manifestations have been observed in 55% of patients (adults and children) (n = 87). These included: headache (28 patients); hydrocephalus (7); epilepsy (5); lacunar stroke (1); white matter disease (1); intraspinal neurofibroma (3); facial palsy (1); radiculopathy (5); and polyneuropathy (2). Tumours included: optic pathway tumours (20); meningioma (2); cerebral glioma (3); and malignant peripheral nerve sheath tumours (6). Life-threatening complications were observed in five adults and included four malignant peripheral nerve sheath tumours and one meningioma. Pain was the leading symptom in 11 adults and was related to malignant peripheral nerve sheath tumours, complications of intraspinal neurofibromas, subcutaneous neurofibromas and peripheral nerve neurofibromas. NF1 in adults was not associated with other disabling or life-threatening neurological complications. Symptomatic optic pathway tumours, cerebral gliomas, symptomatic aqueductal stenosis and spinal compression due to intraspinal NF were observed exclusively during childhood. In this series, the predominant neurological features of adults with NF1 were chronic pain and malignant peripheral nerve sheath tumours. PMID:10094256

    Full Text Available Abstract Background The aims of the present study were to assess symptoms associated with an autism spectrum disorder (ASD in children with neurological disorders as reported by parents and teachers on the Autism Spectrum Screening Questionnaire (ASSQ, as well as the level of agreement between informants for each child. Methods The ASSQ was completed by parents and teachers of the 5781 children (11–13 years who participated in the second wave of the Bergen Child Study (BCS, an on-going longitudinal population-based study. Out of these children, 496 were reported to have a chronic illness, including 99 whom had a neurological disorder. The neurological disorder group included children both with and without intellectual disabilities. Results Children with neurological disorders obtained significantly higher parent and teacher reported ASSQ scores than did non-chronically ill children and those with other chronic illnesses (p Conclusions The ASSQ identifies a high rate of ASD symptoms in children with neurological disorders, and a large number of children screened in the positive range for ASD. Although a firm conclusion awaits further clinical studies, the present results suggest that health care professionals should be aware of potential ASD related problems in children with neurological disorders, and should consider inclusion of the ASSQ or similar screening instruments as part of their routine assessment of this group of children.

  2. Optogenetic cell control in experimental models of neurological disorders.

    Science.gov (United States)

    Tønnesen, Jan

    2013-10-15

    The complexity of the brain, in which different neuronal cell types are interspersed and complexly interconnected, has posed a major obstacle in identifying pathophysiological mechanisms underlying prevalent neurological disorders. This is largely based in the inability of classical experimental approaches to target defined neural populations at sufficient temporal and spatial resolution. As a consequence, effective clinical therapies for prevalent neurological disorders are largely lacking. Recently developed optogenetic probes are genetically expressed photosensitive ion channels and pumps that in principal overcome these limitations. Optogenetic probes allow millisecond resolution functional control over selected optogenetically transduced neuronal populations targeted based on promoter activity. This optical cell control scheme has already been applied to answer fundamental questions pertaining to neurological disorders by allowing researchers to experimentally intercept, or induce, pathophysiological neuronal signaling activity in a highly controlled manner. Offering high temporal resolution control over neural activity at high cellular specificity, optogenetic tools constitute a game changer in research aiming at understanding pathophysiological signaling mechanisms in neurological disorders and in developing therapeutic strategies to correct these. In this regard, recent experimental work has provided new insights in underlying mechanisms, as well as preliminary proof-of-principle for optogenetic therapies, of several neurological disorders, including Parkinson's disease, epilepsy and progressive blindness. This review synthesizes experimental work where optogenetic tools have been applied to explore pathologic neural network activity in models of neurological disorders. PMID:23871610

  3. Neurologic complications of cerebral angiography in childhood moyamoya syndrome

    International Nuclear Information System (INIS)

    Purpose. To determine the incidence of neurologic complications of cerebral angiography in children with moyamoya syndrome (MMS) as compared to children without MMS. Materials and methods. One-hundred-ninety consecutive cerebral angiograms obtained in 152 children were evaluated. Sixty of these angiograms were obtained in 40 children with MMS. Patients underwent neurologic evaluation prior to and after the procedure. For this study, a neurologic complication was defined as any new focal neurologic deficit or alteration in mental status occurring during the procedure or within the ensuing 24 hours. Results. There were 2 neurologic complications within 24 hours of angiography, one in the MMS group and one in the non-MMS group. One patient with MMS became mute following angiography. The symptom resolved within 12 hours. One patient without MMS being examined postoperatively for residual arteriovenous malformation developed intracranial hemorrhage requiring reexploration 12 hours after the angiogram. Using a two-tail Fisher's exact test, there was no significant statistical difference in the ischemic (P = 0.3) or hemorrhagic (P = 1.0) complication rates between the group of patients with MMS and the non-MMS groups. Conclusion. The risk of a neurologic complication from cerebral angiography in children with MMS is low and not statistically different from the risk in children with other cerebrovascular disorders.

    Complications occurring at any level of foetal oxygen supply will result in hypoxaemia, and this may ultimately lead to hypoxia/acidosis and neurological damage. Hypoxic-ischaemic encephalopathy (HIE) is the short-term neurological dysfunction caused by intrapartum hypoxia/acidosis, and this diagnosis requires the presence of a number of findings, including the confirmation of newborn metabolic acidosis, low Apgar scores, early imaging evidence of cerebral oedema and the appearance of clinical signs of neurological dysfunction in the first 48 h of life. Cerebral palsy (CP) consists of a heterogeneous group of nonprogressive movement and posture disorders, frequently accompanied by cognitive and sensory impairments, epilepsy, nutritional deficiencies and secondary musculoskeletal lesions. Although CP is the most common long-term neurological complication associated with intrapartum hypoxia/acidosis, >80% of cases are caused by other phenomena. Data on minor long-term neurological deficits are scarce, but they suggest that less serious intellectual and motor impairments may result from intrapartum hypoxia/acidosis. This chapter focuses on the existing evidence of neurological damage associated with poor foetal oxygenation during labour. PMID:26148854

    Seaweed cultivation is a high growth industry that is primarily targeted at human food and hydrocolloid markets. However, seaweed biomass also offers a feedstock for the production of nutrient-rich biochar for soil amelioration. We provide the first data of biochar yield and characteristics from intensively cultivated seaweeds (Saccharina, Undaria and Sargassum - brown seaweeds, and Gracilaria, Kappaphycus and Eucheuma - red seaweeds). While there is some variability in biochar properties as a function of the origin of seaweed, there are several defining and consistent characteristics of seaweed biochar, in particular a relatively low C content and surface area but high yield, essential trace elements (N, P and K) and exchangeable cations (particularly K). The pH of seaweed biochar ranges from neutral (7) to alkaline (11), allowing for broad-spectrum applications in diverse soil types. We find that seaweed biochar is a unique material for soil amelioration that is consistently different to biochar derived from ligno-cellulosic feedstock. Blending of seaweed and ligno-cellulosic biochar could provide a soil ameliorant that combines a high fixed C content with a mineral-rich substrate to enhance crop productivity.

  11. Minocycline ameliorates cognitive impairment induced by whole-brain irradiation: an animal study

    International Nuclear Information System (INIS)

    It has been long recognized that cranial irradiation used for the treatment of primary and metastatic brain tumor often causes neurological side-effects such as intellectual impairment, memory loss and dementia, especially in children patients. Our previous study has demonstrated that whole-brain irradiation (WBI) can cause cognitive decline in rats. Minocycline is an antibiotic that has shown neuroprotective properties in a variety of experimental models of neurological diseases. However, whether minocycline can ameliorate cognitive impairment induced by ionizing radiation (IR) has not been tested. Thus this study aimed to demonstrate the potential implication of minocycline in the treatment of WBI-induced cognitive deficits by using a rat model. Sprague Dawley rats were cranial irradiated with electron beams delivered by a linear accelerator with a single dose of 20 Gy. Minocycline was administered via oral gavages directly into the stomach before and after irradiation. The open field test was used to assess the anxiety level of rats. The Morris water maze (MWM) was used to assess the spatial learning and memory of rats. The level of apoptosis in hippocampal neurons was measured using immunohistochemistry for caspase-3 and relative markers for mature neurons (NeuN) or for newborn neurons (Doublecortin (DCX)). Neurogenesis was determined by BrdU incorporation method. Neither WBI nor minocycline affected the locomotor activity and anxiety level of rats. However, compared with the sham-irradiated controls, WBI caused a significant loss of learning and memory manifest as longer latency to reach the hidden platform in the MWM task. Minocycline intervention significantly improved the memory retention of irradiated rats. Although minocycline did not rescue neurogenesis deficit caused by WBI 2 months post-IR, it did significantly decreased WBI-induced apoptosis in the DCX positive neurons, thereby resulting in less newborn neuron depletion 12 h after irradiation

    Creating curriculums that develop physical therapy (PT) students into evidenced-based, critically reflective, entry-level practitioners is one of the primary goals for PT programs. Academic faculty partnering with neurologic residency programs to design learning environments that capitalize upon the strengths of both can create insightful educational experiences for students during their didactic training. These partnerships support the development of critical thinking skills and provide mentorship for residents transitioning from their role as a clinician to that of an educator. Using the SOLO (structure of observed learning outcomes) taxonomy as a framework for developing learning experiences, Seton Hall University neurologic academic faculty and program directors from the Kessler Institute for Rehabilitation Residency in Neurologic Physical Therapy have built a partnership that seeks to develop critical reflection skills in both the neurologic resident and entry-level PT students. While integration of residents into entry-level PT curriculum may not be novel, we believe that utilizing the SOLO model within this partnership is unique. This paper describes the partnership and learning experiences rooted in the SOLO taxonomy theoretical framework and discusses perceived benefits of this learning experience across professional health science programs.

    In German neurorehabilitation, the ambiguous term "early rehabilitation" reflects the multidisciplinary, rehabilitative treatment of severely impaired patients in continuing need of acute and intensive care (including weaning from the respirator in selected cases). The actual definition of this treatment is discussed, which hitherto corresponded to Phase B according to recommendations of the German Federal Study Group for Rehabilitation (BAR) and now has started to be integrated into the diagnosis-related group system. The tasks and aims of early rehabilitation are to support and enhance neuroplastic remission of nervous system functional loss and continued medical care, improve vigilance, establish cooperativity, and evaluate the rehabilitation potential including compensatory and adaptive strategies organizing posthospital care, reducing the need of nursing support, and improving quality of life. Some special aspects of early rehabilitative care are presented here in more detail. To fulfill these tasks, a multidisciplinary team is required including various therapists qualified for neurorehabilition, physicians (including a neurologist), nurses, and social workers. Outcome data were assessed using our 5-year prospective early rehabilitation registry. Fifty-five percent of patients improved to reach the next step of neurorehabilitation (Phase C), with significant gain in function even in the subgroup of aged and most severely disabled patients. The trend to transfer patients very early in the postacute Phase to early rehabilitation facilities, with open medical problems and increased risk of complications, makes close cooperation and interaction with acute medical centers necessary.

    Full Text Available Objective(s: Multiple sclerosis (MS is a serious neurological autoimmune disease, it commonly affects young adults. Vitamin E (Vit E is an important component of human diet with antioxidant activity, which protects the body’s biological systems. In order to assess the effect of Vit E treatment on this autoimmune disease, we established experimental autoimmune encephalomyelitis (EAE, the animal model of MS, and treated EAE with α-tocopherol (AT which is the main content of Vit E. Materials and Methods:Twenty C57BL/6 adult female mice were used and divided into two groups randomly. EAE was induced with myelin oligodendrocyte glycoprotein (MOG, and one group was treated with AT, at a dose of 100 mg/kg on the 3th day post-immunization with MOG, the other group was treated with 1% alcohol. Mice were euthanized on day 14, post-immunization, spleens were removed for assessing splenocytes proliferation and cytokine profile, and spinal cords were dissected to assess the infiltration of inflammatory cells in spinal cord. Results:AT was able to attenuate the severity of EAE and delay the disease progression. H&E staining and fast blue staining indicated that AT reduced the inflammation and the demyelination reaction in the spinal cord. Treatment with AT significantly decreased the proliferation of splenocytes. AT also inhibited the production of IFN-γ (Th1 cytokine, though the other cytokines were only affected slightly. Conclusion:According to the results, AT ameliorated EAE, through suppressing the proliferation of T cells and the Th1 response. AT may be used as a potential treatment for MS.

    Enterovirus 71 frequently involves the central nervous system and may present with a variety of neurologic manifestations. Here, we aimed to describe the clinical features, magnetic resonance imaging (MRI) findings, and cerebrospinal fluid (CSF) profiles of patients presenting with neurologic complications of enterovirus 71 infection. We retrospectively reviewed the records of 31 pediatric patients hospitalized with acute neurologic manifestations accompanied by confirmed enterovirus 71 infection at Ulsan University Hospital between 2010 and 2014. The patients' mean age was 2.9 ± 5.5 years (range, 18 days to 12 years), and 80.6% of patients were less than 4 years old. Based on their clinical features, the patients were classified into 4 clinical groups: brainstem encephalitis (n = 21), meningitis (n = 7), encephalitis (n = 2), and acute flaccid paralysis (n = 1). The common neurologic symptoms included myoclonus (58.1%), lethargy (54.8%), irritability (54.8%), vomiting (48.4%), ataxia (38.7%), and tremor (35.5%). Twenty-five patients underwent an MRI scan; of these, 14 (56.0%) revealed the characteristic increased T2 signal intensity in the posterior region of the brainstem and bilateral cerebellar dentate nuclei. Twenty-six of 30 patients (86.7%) showed CSF pleocytosis. Thirty patients (96.8%) recovered completely without any neurologic deficits; one patient (3.2%) died due to pulmonary hemorrhage and shock. In the present study, brainstem encephalitis was the most common neurologic manifestation of enterovirus 71 infection. The characteristic clinical symptoms such as myoclonus, ataxia, and tremor in conjunction with CSF pleocytosis and brainstem lesions on MR images are pathognomonic for diagnosis of neurologic involvement by enterovirus 71 infection.

    Cognitive symptoms such as poor memory and concentration represent a common cause of morbidity among patients presenting to general practitioners and may result in referral for a neurological opinion. In many cases, these symptoms do not relate to an underlying neurological disease or dementia. In this article we present a personal perspective on the differential diagnosis of cognitive symptoms in the neurology clinic, especially as this applies to patients who seek advice about memory problems but have no neurological disease process. These overlapping categories include the following 'functional' categories: 1) cognitive symptoms as part of anxiety or depression; 2) "normal" cognitive symptoms that become the focus of attention; 3) isolated functional cognitive disorder in which symptoms are outwith 'normal' but not explained by anxiety; 4) health anxiety about dementia; 5) cognitive symptoms as part of another functional disorder; and 6) retrograde dissociative (psychogenic) amnesia. Other 'non-dementia' diagnoses to consider in addition are 1) cognitive symptoms secondary to prescribed medication or substance misuse; 2) diseases other than dementia causing cognitive disorders; 3) patients who appear to have functional cognitive symptoms but then go on to develop dementia/another neurological disease; and finally 4) exaggeration/malingering. We discuss previous attempts to classify the problem of functional cognitive symptoms, the importance of making a positive diagnosis for the patient, and the need for large cohort studies to better define and manage this large group of patients.

    This chapter explores iconography in neurology from the birth of photography up to the early medical applications of cinematography before 1914. The important visual part of neurological diagnosis explains why these techniques were adopted very early by neurologists. Duchenne published the first medical book illustrated with photographs of patients. The first and most famous photographic laboratory was created in Charcot's department, at the Salpêtrière in Paris, under the direction of Albert Londe. Londe published the first book dedicated to medical photography. The physiologist Marey and the photographer Muybridge, in association with neurologists, played key roles in the development of chronophotography and cinematography. Germany was the first country to welcome cinematography in a neurology department. Independently, neurologists began to film patients in other countries in Europe and in America. In 1905, Arthur Van Gehuchten (1861-1914), Belgian anatomist and neurologist, began systematically to film neurologic patients, with the intention of building up a complete neurological iconographic collection. This collection has survived and has been restored in the laboratory of the Royal Belgian Film Archive where the films are now safely stored in their vaults. PMID:19892123

    International Nuclear Information System (INIS)

    To determine the outcome of treatment of microsurgical clipping in elderly (60 - 70 years) patients with aneurysmal subarachnoid hemorrhage and determine the predictors of poor outcome. Study Design: Longitudinal analytical study. Place and Duration of Study: Nishtar Hospital, Multan, Mayo Hospital, Lahore, Department of Neurosurgery, Lahore General Hospital, Lahore, from January 2000 to January 2010. Methodology: Elderly patients (60 - 70 years) with ruptured cerebral aneurysm were enrolled and graded on the basis of World Federation of Neurosurgeons Scale (WFNS). Aneurysm sac obliteration was done in all the patients with microsurgical clipping. Postoperatively, the patients were assessed upto 3 months for outcome parameters i.e., neurological deterioration (based on WFNS grade and modified Rankin scale as favourable (mRS score 2). The factors associated with unfavourable outcome were also noted which included age > 65 years, poor initial WFNS grade, and the occurrence of ischaemia. Results: The mean age of the 48 patients was 65 + 5.45 years. There were 31 (64.6%) male and 17 (35.4%) female patients. Postprocedural neurological deterioration occurred in 23 patients (47.9%) related to ischaemia in 14 (29.16%), rebleeding in 1 (2%), and hydrocephalus in 8 (16.66%). At 03 months, the outcome was favourable in 25 patients (52.08%) and unfavourable in 23 (47.91%). Conclusion: In old patients, careful pre-operative assessment, interdisciplinary approach and meticulous tissue handling during aneurysm clipping may decrease the unfavourable outcome. (author)

    Full Text Available Background: This paper is concerned with the development of ameliorating inventory models. The ameliorating inventory is the inventory of goods whose utility increases over the time by ameliorating activation. Material and Methods: This study is performed according to two areas: one is an economic order quantity (EOQ model for the items whose utility is ameliorating in accordance with Weibull distribution, and the other is a partial selling quantity (PSQ model developed for selling the surplus inventory accumulated by ameliorating activation with linear demand. The aim of this paper was to develop a mathematical model for inventory type concerned in the paper. Numerical examples were presented show the effect of ameliorating rate on inventory polices.  Results and Conclusions:  The inventory model for items with Weibull ameliorating is developed. For the case of small ameliorating rate (less than linear demand rate, EOQ model is developed, and for the case where ameliorating rate is greater than linear demand rate, PSQ model is developed.  .  

  5. The relationship between cerebral oxygen saturation changes and post operative neurologic complications in patients undergoing cardiac surgery

    International Nuclear Information System (INIS)

    To study the relationship between cerebral oxygen saturation changes and postoperative neurologic complications. Seventy two adult patients with ASA class II, III who were scheduled for elective cardiac surgery, were randomized into three groups: Group I: with CPB (on -pump) Group II: without CPB (off- pump) Group III: valve surgery. Neuropsychological outcome was assessed by the Mini-Mental State Examination (MMSE). Cerebral oxygen saturation was also measured. There was no statistical difference in desaturation of more than 20% among three groups (P=0.113) but it was significant between group I and II (P=0.042). Changes of rSo/sub 2/ in different hours of surgery was significant in group I and group II (P=0.0001 in both) but it was not significant in group III ( P=0.075) . Although cerebral oximetry is a noninvasive and useful method of monitoring during cardiac surgery, it has low accuracy to determine postoperative neurologic complications. (author)

    Full Text Available Obsessive–compulsive disorder (OCD is an increasingly recognized disorder with a prevalence of 2–3% (Robins et al., 1984. Once thought to be psychodynamic in origin, OCD is now generally recognized as having a neurobiological cause. Although the exact pathophysiology of OCD in its pure form remains unknown, there are numerous reports of obsessive–compulsive symptoms arising in the setting of known neurological disease. In this paper, we review the reported cases of obsessive–compulsive symptoms associated with neurologic diseases and outline the known facts about the underlying neurobiology of OCD. Finally, we synthesize these findings into a proposed theory of the pathophysiology of OCD, in both its pure form and when it accompanies other neurological illness.

  7. PET molecular imaging in stem cell therapy for neurological diseases

    International Nuclear Information System (INIS)

    Human neurological diseases such as Alzheimer's disease, Parkinson's disease, Huntington's disease, spinal cord injury and multiple sclerosis are caused by loss of different types of neurons and glial cells in the brain and spinal cord. At present, there are no effective therapies against these disorders. Discovery of the therapeutic potential of stem cells offers new strategies for the treatment of neurological diseases. Direct assessment of stem cells' survival, interaction with the host and impact on neuronal functions after transplantation requires advanced in vivo imaging techniques. Positron emission tomography (PET) is a potential molecular imaging modality to evaluate the viability and function of transplanted tissue or stem cells in the nervous system. This review focuses on PET molecular imaging in stem cell therapy for neurological diseases. (orig.)

    Full Text Available Neurological diseases, which consist of acute injuries and chronic neurodegeneration, are the leading causes of human death and disability. However, the pathophysiology of these diseases have not been fully elucidated, and effective treatments are still lacking. Astaxanthin, a member of the xanthophyll group, is a red-orange carotenoid with unique cell membrane actions and diverse biological activities. More importantly, there is evidence demonstrating that astaxanthin confers neuroprotective effects in experimental models of acute injuries, chronic neurodegenerative disorders, and neurological diseases. The beneficial effects of astaxanthin are linked to its oxidative, anti-inflammatory, and anti-apoptotic characteristics. In this review, we will focus on the neuroprotective properties of astaxanthin and explore the underlying mechanisms in the setting of neurological diseases.

    This paper presents the Collaborative Tele-Neurology (TeNeCi) project which allows practitioners to use telecommunication technologies to provide medical information and services for neurological diseases. Specificities of remote neurology are described and the Cooperative Application Framework (CAliF) multimedia platform on which TeNeCi relies is presented. The technical requirements of such a project in terms of communication and consistency management, audio and video transmissions, and network support, as well as implementation of TeNeCi was evaluated. The software used in this application is composed of several services, such as a Digital Imaging and Communications in Medicine (DICOM) explorer, a DICOM viewer, and a security service. Tests performed on this first TeNeCi release showed good results, and allowed us to explore a larger collaborative experimentation between hospitals in France and Switzerland. PMID:16430389

    Human neurological diseases such as Alzheimer's disease, Parkinson's disease, Huntington's disease, spinal cord injury and multiple sclerosis are caused by loss of different types of neurons and glial cells in the brain and spinal cord. At present, there are no effective therapies against these disorders. Discovery of the therapeutic potential of stem cells offers new strategies for the treatment of neurological diseases. Direct assessment of stem cells' survival, interaction with the host and impact on neuronal functions after transplantation requires advanced in vivo imaging techniques. Positron emission tomography (PET) is a potential molecular imaging modality to evaluate the viability and function of transplanted tissue or stem cells in the nervous system. This review focuses on PET molecular imaging in stem cell therapy for neurological diseases. (orig.)

    Full Text Available Neurologic complications of human immunodeficiency virus (HIV infection and acquired immune deficiency syndrome (AIDS frequently lead to disability or death in affected patients. The aim of this study was to determine whether survival patterns differ between men and women with HIV/AIDS-related neurologic disease (neuro-AIDS.Retrospective cohort data from a statewide surveillance database for HIV/AIDS were used to characterize survival following an HIV/AIDS-related neurologic diagnosis for men and women with one or more of the following conditions: cryptococcosis, toxoplasmosis, primary central nervous system lymphoma, progressive multifocal leukoencephalopathy, and HIV-associated dementia. A second, non-independent cohort was formed using university-based cases to confirm and extend the findings from the statewide data. Kaplan-Meier analysis was used to compare the survival experiences for men and women in the cohorts. Cox regression was employed to characterize survival while controlling for potential confounders in the study population.Women (n=27 had significantly poorer outcomes than men (n=198 in the statewide cohort (adjusted hazard ratio=2.31, 95% CI: 1.22 to 4.35, and a similar, non-significant trend was observed among university-based cases (n=17 women, 154 men. Secondary analyses suggested that this difference persisted over the course of the AIDS epidemic and was not attributable to differential antiretroviral therapy responses among men and women.The survival disadvantage of women compared to men should be confirmed and the mechanisms underlying this disparity elucidated. If this relationship is confirmed, targeted clinical and public health efforts might be directed towards screening, treatment, and support for women affected by neuro-AIDS.

Materials and Methods: Prospective cross-sectional study conducted in the neurological rehabilitation unit of tertiary research hospital in 30 consecutive hospitalized patients (21 men, age 16-55 years (34.63±11.87. Outcome Measure: WHOQoL-BREF was used to assess QoL. The prevalence of PP was recorded using Hospital Anxiety Depression Scale (HADS and General Health Questionnaire (GHQ-12. QoL and HADS scores were correlated with functional abilities using mean Barthel Index (BI Score. Results: The duration of illness was three to 30 months (10.63±7.83 and their primary diagnoses were stroke 12, traumatic spinal cord injury seven and non-traumatic spinal cord lesion 11. Twenty-two patients qualified for GHQ-12 caseness, with 15 patients having distress (score ≥15 and seven having severe problem and psychological distress (score≥20. Twenty five patients had abnormal anxiety and 17 had abnormal depression on HADS (abnormal = 8-21, with moderate to severe anxiety and depression (scores≥11 in nine and three patients respectively. The mean WHOQoL-BREF transformed scores (on WHOQoL 0-100 scale were (38.83±8.02, (50.76±9.79, (48.53±18.46 and (49.13±10.63 in physical, psychological, social, and environmental domains respectively. The social domain of QoL had significant correlation ( P < .05 with functional abilities. Conclusion: Patients with neurological disorders requiring inpatient rehabilitation have impaired QoL that affects all domains of life. There is high prevalence of psychological problems, including anxiety and depression. The social domain of QoL adversely affected functional abilities, but the correlation between PP and functional abilities was insignificant.

    Carnuba wax (as binder) forms hard tablets even at low compression load attributable to its high plasticity. The aim of the present study is to investigate its potential in ameliorating brittle fracture (i.e., lamination and capping) a problem often encountered during tableting. Granules of paracetamol (test drug) were made by triturating the drug powder with the melted wax or starch mucilage (20%w/v). Resulting granules were separated into different size fractions which were separately compressed into tablets with and without a centre hole (as in- built defect) using different compression loads. The tablets were evaluated for tensile strength and the data used to calculate the brittle fracture index (BFI), using the expression: BFI = 0.5(T/T(0)-1) where T0 and T are the tensile strength of tablets with and without a centre hole respectively. The BFI values were significantly lower (pload further ameliorated the brittle fracture tendency of the tablets. Using granules with the larger particle size (850microm) and applying the lowest unit of load (6 arbitrary unit on the load scale of the tableting machine) the BFI values were 0.03 (carnuba wax tablets) and 0.11 (maize starch tablets). When the conditions were reversed (i.e., a highest load, 8 units and the smallest particle size, 212microm) the BFI values now became 0.17 (carnuba wax tablets) and 0.26 (maize starch tablets). The indication is that the use of large granules and low compression loads to form tablets can further enhance the potential of carnuba wax in ameliorating brittle fracture tendency of tablets during their manufacture.

    Background: Neurologic complications may be the first symptoms of atrial myxomas. Understanding the imaging features of neurologic complications of atrial myxomas can be helpful for the prompt diagnosis. Objective: To identify neuroimaging features for patients with neurologic complications attributed to atrial myxoma. Methods: We retrospectively reviewed the medical records of 103 patients with pathologically confirmed atrial myxoma at Xiangya Hospital from January 2009 to January 2014. The neuroimaging data for patients with neurologic complications were analyzed. Results: Eight patients with atrial myxomas (7.77%) presented with neurologic manifestations, which constituted the initial symptoms for seven patients (87.5%). Neuroimaging showed five cases of cerebral infarctions and three cases of aneurysms. The main patterns of the infarctions were multiplicity (100.0%) and involvement of the middle cerebral artery territory (80.0%). The aneurysms were fusiform in shape, multiple in number (100.0%) and located in the distal middle cerebral artery (100.0%). More specifically, high-density in the vicinity of the aneurysms was observed on CT for two patients (66.7%), and homogenous enhancement surrounding the aneurysms was detected in the enhanced imaging for two patients (66.7%). Conclusion: Neurologic complications secondary to atrial myxoma consist of cerebral infarctions and aneurysms, which show certain characteristic features in neuroimaging. Echocardiography should be performed in patients with multiple cerebral infarctions, and multiple aneurysms, especially when aneurysms are distal in location. More importantly, greater attention should be paid to the imaging changes surrounding the aneurysms when myxomatous aneurysms are suspected and these are going to be the relevant features in our article.

    The article discusses the consequences for neurology as a discipline which resulted from neurologists' participation in the crimes committed under National Socialism (NS). Chronologically, the current literature distinguishes mainly four overlapping stages: (1) a first phase was characterized by legal persecution and "denazification", which was also the time of the Nuremberg doctors' trial in which no neurologists were on trial. A detailed documentation of the trial for the German medical profession was published by Alexander Mitscherlich. (2) In the subsequent practice of wide amnestying and reintegration of former Nazi followers during the 1950s, neurologists were no exception as its elite continued in their positions. The year 1953 was the year of the Lisbon scandal, when chiefly Dutch representatives protested against the participation of Julius Hallervorden in the International Congress of Neurology. The newly founded societies, the German Society for Neurology (Deutsche Gesellschaft für Neurologie, DGN) and the German Society for Psychiatry and Neurology (Deutsche Gesellschaft für Psychiatrie und Neurologie, DGPN), unanimously supported their member. (3) The next period was characterized by a nascent criticism of the prevailing attitude of covering up the crimes committed by physicians during the Nazi period. The discovery of incriminating brain sections at various Max Planck Institutes brought neurology to the focus of the debate. (4) Since the 1980s and 1990s historians (of medicine) have been systematically examining medicine's Nazi past in a professional way, which resulted in a noticeable increase of knowledge. Additionally, a new generation of scholars provoked a change of mind insofar as they recognized medicine's responsibility for the crimes committed between 1933 and 1945. We expect that future historical research will further elucidate the history of neurology during the NS regime and have consequences for our current understanding of research

    This study examined the benefits of incorporating screening for distress as a routine part of care for patients with head and neck and neurologic cancers in a tertiary cancer center. Using a comparative 2-cohort pre-post implementation sequential design, consecutive outpatients with head and neck and neurologic cancers were recruited into 2 separate cohorts. Cohort 1 included patients attending clinics during April 2010, before the implementation of the screening program. The program was then implemented and patients completed the Screening for Distress Minimum Dataset (the Edmonton Symptom Assessment System [ESAS] and the Canadian Problem Checklist [CPC]) at each clinic visit. Cohort 2 included patients attending clinics during March 2011. Consenting patients completed screening and outcome measures (ESAS, CPC, and either the Functional Assessment of Cancer Therapy-Brain or the Functional Assessment of Cancer Therapy-Head and Neck). A total of 146 patients (78 head and neck and 68 neurologic) provided data for Cohort 1, and 143 (81 head and neck and 62 neurologic) provided data for Cohort 2. Compared with Cohort 1, patients with neurologic cancers in Cohort 2 reported significantly higher scores on the Functional Assessment of Cancer Therapy: General total and emotional quality of life subscale; fewer high scores (≥ 4) on the ESAS breathlessness item; and fewer problems with fears/worries, frustration/anger, finding meaning in life, and worry about friends/family. Head and neck patients in Cohort 2 reported significantly higher emotional quality of life and fewer problems with eating and weight than those in Cohort 1. Although no definitive causal attributions can be made, patients exposed to routine screening for distress reported better well-being and fewer emotional, physical, and practical problems than historical controls.

    Neutrophils have been recognized as critical response cells during the pathogenesis of endotoxin‑induced uveitis (EIU). Apoptosis of neutrophils induced by roscovitine has previously been demonstrated to ameliorate inflammation in several in vivo models. The present study aimed to assess whether roscovitine ameliorates EIU. EIU was induced in female C57BL/6 mice by a single intravitreal injection of lipopolysaccharide (LPS; 250 ng). The mice were divided into three groups as follows: LPS alone, LPS plus vehicle, LPS plus roscovitine (50 mg/kg). The mice were euthanized 12, 24, 48 and 72 h after LPS‑induced uveitis. Accumulation of inflammatory cells in the vitreous body was confirmed by immunohistochemistry, and quantified following hematoxylin and eosin staining. Terminal deoxynucleotidyl transferase dUTP nick‑end labeling was performed to detect of apoptotic cells. The mRNA levels of inflammatory cytokines were analyzed by reverse transcription‑quantitative polymerase chain reaction and the changes in protein levels were analyzed by western blotting. Inflammatory cells accumulated in the vitreous near the optic nerve head and the quantity peaked at 24 h after LPS injection. Immunohistochemistry revealed that the majority of the inflammatory cells were neutrophils. The number of infiltrating cells was similar in the LPS and LPS plus vehicle groups, while there were significantly less in the roscovitine group at 24 h. Apoptosis of neutrophils was observed between 12 and 48 h after roscovitine injection, while no apoptosis was observed in the other groups. The mRNA expression levels of GMCSF, CINC‑1 and ICAM‑1 peaked at 12 h after LPS injection, and decreased to normal levels at 72 h. This trend in mRNA expression was similar in the LPS and LPS plus vehicle groups; however, the expression levels decreased more quickly in the roscovitine group at 24 and 48 h. Following roscovitine administration, upregulated cleaved caspase 3 expression levels

    A total of 198 neurological patients on physiotherapeutic rehabilitation participated in a questionnaire survey on their quality of life. The patients had diabetic polyneuropathy (n = 86), disorders in spinal blood circulation (n = 65), 47 patients were operated for discal hernia of the lumbar spine. It was found that all the responders suffer from physical, psychological, emotional and social sequelae of their diseases which deteriorate their quality of life. The severity of this deterioration depends on the form and stage of the disease, motor and sensitive disturbances. Rehabilitation improved subjective response, social, psychological and emotional parameters. Thus, the proposed questionnaires proved valid for assessment of physiotherapy efficacy in neurological patients. PMID:16752737

We describe how individuals courageously and intelligently dealt with the horrors of war, from the Egyptians to the Greeks and onward to the Romans, up until the physicians of modern times. In doing so, they responded to the call of duty by inventing solutions that benefitted not only soldiers but also civilian medicine. PMID:27035675

    International Nuclear Information System (INIS)

    Cerebral perfusion deficits detected by injection of 99Tcm-hexamethylpropyleneamine oxime (HMPAO) and single photon emission tomography is said to correlate well with clinical findings in divers with neurological decompression illness. We studied 12 divers. Six had residual cerebral signs (group 1) and six had no residual cerebral symptoms or signs (group 2). Perfusion deficits were as common in group 2 as in group 1. The site of the deficit did not correlate well with either the neurological findings at presentation or the residual clinical signs after treatment. The data suggest that claims that HMPAO scanning correlates with clinical findings and can be used for patient management were incorrect. (author)

    B7-H3, a recently discovered B7 family member, is documented as a regulator in the inflammatory response as well as T cell-mediated immune responses. In this paper, we find that patients with acute pancreatitis revealed overwhelming levels of serum soluble B7-H3 (sB7-H3) associated with the clinical outcomes. Furthermore, B7-H3 protein was marked increased in l-arginine-induced acute experimental pancreatitis. Anti-B7-H3 monoclonal antibody treatment attenuated the proinflammatory cytokine production, downregulated the activation of the NF-κB signaling pathway, and ameliorated the pancreas disruption in l-arginine-induced pancreatitis. In addition, although l-arginine alone failed to induce the production of proinflammatory cytokine and anti-B7-H3 mAb had no effect on the proinflammatory cytokine production of acinar cells, administration of anti-B7-H3 mAb in the coculture model of acinar cells and macrophages stimulated by l-arginine displayed the similar effects. On the whole, B7-H3 participates in the development of acute pancreatitis, and anti-B7-H3 monoclonal antibody ameliorates severity of acute experimental pancreatitis via attenuation of the inflammatory response.

    The activated nuclear factor-KappaB signaling pathway plays a critical role in inducing inflammatory injury. It has been reported that electroacupuncture could be an effective anti-inflammatory treatment. We aimed to explore the complex mechanism by which EA inhibits the activation of the NF- κ B signal pathway and ameliorate inflammatory injury in the short term; the effects of NEMO Binding Domain peptide for this purpose were compared. Focal cerebral I/R was induced by middle cerebral artery occlusion for 2 hrs. Total 380 male Sprague-Dawley rats are in the study. The neurobehavioral scores, infarction volumes, and the levels of IL-1 β and IL-13 were detected. NF- κ B p65, I κ B α , IKK α , and IKK β were analyzed and the ability of NF- κ B binding DNA was investigated. The EA treatment and the NBD peptide treatment both reduced infarct size, improved neurological scores, and regulated the levels of IL-1 β and IL-13. The treatment reduced the expression of IKK α and IKK β and altered the expression of NF- κ B p65 and I κ B α in the cytoplasm and nucleus; the activity of NF- κ B was effectively reduced. We conclude that EA treatment might interfere with the process of NF- κ B nuclear translocation. And it also could suppress the activity of NF- κ B signaling pathway to ameliorate the inflammatory injury after focal cerebral ischemia/reperfusion. PMID:23970940

Neurological complications were monitored by measuring serum concentrations of neuropeptide proenkephalin A (PENK-A and protachykinin A (PTA before and in the first 5 days after surgery, comparing the neurological outcome with MRI examinations. Results Both the erythropoietin-treated group and control group were comparable with a non-significant difference shown for the postoperative concentrations of PENK-A and PTA. A comparison of serum concentrations of the biomarkers of 16 patients without brain ischemia and 4 patients with acute ischemia also displayed no significant differences, regardless of erythropoietin therapy. Conclusion In our pilot study the analysis of PENK-A and PTA serum concentrations might not be the strategy to enable the monitoring and evaluation of neuroprotective stroke treatment, but further studies are required to investigate its role in acute ischemic brain injury.

    Full text: Introduction: Several studies have shown the value of PET in diagnosing occult tumours in patients with paraneoplastic neurological syndromes (PNS). Objective: To audit our experience with PET in the diagnosis of occult tumours in PNS. Methods: A retrospective analysis of all PET and PET/CT scans done for PNS in South Australia from the time the PET/CT was installed (2002) till September 2008. Results of antibody tests, imaging, final diagnosis and outcome were obtained with a mean follow up of 8I9 days. Results: 24 patients (15 women), mean age 62 (range 36-80) were included. The mean interval between symptom onset and PET was 19 days (range 3-29). There were a variety of PNS including subacute sensory neuropathy, cerebellar syndrome. encephalitis, Lambert Eaton myasthenic syndrome, myopathy, transverese myelitis and subacute global neurological deterioration. Abnormal FDG uptake was seen in eight but malignancy was only confirmed in 2 patients. One patient died shortly after PET/CT likely because of lung malignancy. There were 5 false positives. At follow up 14 had no formal diagnosis, 4 had autoimmune illness and in 3 the diagnosis of PNS was revised. The sensitivity was 100%, specificity 76%, positive predictive value 37.5% and negative predictive value 100%. Conclusion: PET was positive in only 12.5% of these patients. When the 3 patients without PNS are excluded the diagnostic yield of PET is 43%. PET is a useful tool in PNS but patient selection is important.

  12. Findings at brain MRI in children with dengue fever and neurological symptoms

    International Nuclear Information System (INIS)

    Dengue is a flavivirus of the genus arbovirus with four serotypes, from DEN 1 to DEN 4. There has been an increase in incidence of dengue infection in children in the tropics and subtropics. Dengue has a variable clinical presentation, with many patients being asymptomatic. Its clinical manifestations in children vary from fever and arthralgia to life-threatening dengue hemorrhagic fever and dengue shock syndrome. We describe MRI findings in children with neurological involvement including dengue encephalopathy, acute hypoxic injury and dengue encephalitis. Dengue encephalopathy is usually secondary to multisystem derangement such as shock, hepatitis, coagulopathy and concurrent bacterial infection and is relatively common. Dengue encephalitis from direct neuronal invasion is rare. Nonspecific changes are seen on brain MRI in dengue infection. Clinical and laboratory findings as well as outcome do not necessarily correspond with brain MRI findings. (orig.)

    Full Text Available Abstract Background Prognosis assessment of patients with infectious and neoplastic disorders of the central nervous system (CNS may still pose a challenge. In this retrospective cross-sectional study the prognostic value of basic cerebrospinal fluid (CSF parameters in patients with bacterial meningitis, viral meningoencephalitis and leptomeningeal metastases were evaluated. Methods White blood cell count, CSF/serum glucose ratio, protein, CSF/serum albumin quotient and Immunoglobulin indices for IgG, IgA and IgM were analyzed in 90 patients with bacterial meningitis, 117 patients with viral meningoencephalitis and 36 patients with leptomeningeal metastases in a total of 480 CSF samples. Results In the initial spinal tap, the IgG-index was the only independent predictor for unfavorable outcome (GOS Conclusion The present study suggests that in infectious CNS diseases an elevated IgG-Index might be an additional marker for the early identification of patients at risk for neurological morbidity.

    Material and Methods: Thirty-eight late-diagnosed classic phenylketonuria patients were enrolled in the study. Plasma phenylalanine levels were measured by spectrofluorometric method. MRI was evaluated by a pediatric neuroradiologist. Ankara developmental screening inventory (ADSI and Wechsler intelligence scale for Turkish children (WISC-R test were performed to detect IQ scores. Porteus Mazo test adapted for Turkish children intelligence test were performed to all children. The EEG of all patients were recorded. VEP was used to measure the electrical activity in the brain to visual stimulus. Results: The high plasma phenylalanine levels and late-diagnosis were associated with low IQ scores, pathological EEG, and pathological VEP patterns. High PA levels were also associated with more serious white matter signal abnormalities. Conclusion: Our results demonstrated the impact of early diagnosis and low levels of phenylalanine at diagnosis on the intellectual, neurological development and visual outcomes.

    Full Text Available The present study was aimed at investigating the ameliorative effect of Tinospora cordifolia in sciatic nerve root Ligation -induced sciatica pain in rats. Adult male albino rats weighing 130-150gm were used for the study, and were divided into seven groups and ligation was performed on left sciatic nerve in group II to group VII. Tail cold-hyperalgesia, motor co-ordination tests, foot deformity, and total calcium levels were estimated to assess the extent of sciatica. Superoxide dismutase (SOD, catalase (CAT, and lipid peroxide (LPO levels were estimated to evaluate the extent of oxidative stress. The alcoholic and aqueous extract of Tinospora cordifolia was administered at a dose of 100 and 200 mg/kg/p.o for 15 days. Tinospora cordifolia attenuated sciatic nerve root Ligation-induced motor in-coordination, foot deformity, tail cold hyperalgesia, reversed ligation-induced alterations in lipid peroxides, total calcium, superoxide dismutase, catalase levels in a dose-dependent manner. Ameliorative effects of Tinospora cordifolia in ligation-induced sciatica may be due to its foot deformity, antioxidant, and calcium attenuating actions.

    Full Text Available Gentamicin nephrotoxicity is one of the most common causes of acute renal failure. Simvastatin is one of the antioxidative drugs, which has anti-inflammatory and anabolic effects and modulates the immune system. The present study was conducted to assess the effect of simvastatin on ameliorating the gentamicin-induced renal injury in 87 Sprague-Dawley rats, which were allocated randomly to 11 study groups: (A and (B groups with only gentamicin in 2 dosages; (C, (D, and (E gentamicin 50 mg/kg/day and simvastatin with different dosage; (F, (G, and (H gentamicin 80 mg/kg/day and simvastatin with different dosage; (I only simvastatin; (J Injected normal saline; (K control (no gentamicin and no simvastatin group. Our study intervention period for injection of drugs was 12 days. Serum creatinine level and clearance were measured in all groups. At the end of the study, the rats were killed and both kidneys were removed and processed for histopathologic examination using the standard methods. The 50 mg/kg/day dose was utilized because it induces a mild form of renal toxicity, whereas the 80 mg/kg/day dose cause a more severe degree of renal injury. Morphologic examination of specimens from all rats was qualitatively assessed with blindness to treatment groups and proximal tubular profiles that were presented in each file were counted. The results demonstrated amelioration of gentamicin-induced renal toxicity in rats by simvastatin due to its antioxidant drug dose-related effect.

    Hypobaric hypoxia (HH) observed at high altitude causes mild cognitive impairment specifically affecting attention and working memory. Adrenergic dysregulation and neuronal damage in prefrontal cortex (PFC) has been implicated in hypoxia induced memory deficits. Optimal stimulation of alpha 2A adrenergic receptor in PFC facilitates the spatial working memory (SWM) under the conditions of adrenergic dysregulation. Therefore the present study was designed to test the efficacy of alpha 2A adrenergic agonist, Guanfacine (GFC), to restore HH induced SWM deficits and PFC neuronal damage. The rats were exposed to chronic HH equivalent to 25,000ft for 7days in an animal decompression chamber and received daily treatment of GFC at a dose of 1mg/kg body weight via the intramuscular route during the period of exposure. The cognitive performance was assessed by Delayed Alternation Task (DAT) using T-Maze and PFC neuronal damage was studied by apoptotic and neurodegenerative markers. Percentage of correct choice decreased significantly while perseverative errors showed a significant increase after 7days HH exposure, GFC significantly ameliorated the SWM deficits and perseveration. There was a marked and significant increase in chromatin condensation, DNA fragmentation, neuronal pyknosis and fluoro Jade positive cells in layer II of the medial PFC in hypoxia exposed group, administration of GFC significantly reduced the magnitude of these changes. Modulation of adrenergic mechanisms by GFC may serve as an effective countermeasure in amelioration of prefrontal deficits and neurodegenerative changes during HH. PMID:24184415

    Full Text Available Oxidative stress has been implicated to play a role, at least in part, in pathogenesis of many disease conditions and toxicities in animals. Overproduction of reactive oxygen species and free radicals beyond the cells intrinsic capacity to neutralize following xenobiotics exposure leads to a state of oxidative stress and resultant damages of lipids, protein, and DNA. Lead and cadmium are the common environmental heavy metal pollutants and have widespread distribution. Both natural and anthropogenic sources including mining, smelting, and other industrial processes are responsible for human and animal exposure. These pollutants, many a times, are copollutants leading to concurrent exposure to living beings and resultant synergistic deleterious health effects. Several mechanisms have been explained for the damaging effects on the body system. Of late, oxidative stress has been implicated in the pathogenesis of the lead- and cadmium-induced pathotoxicity. Several ameliorative measures to counteract the oxidative damage to the body system aftermath or during exposure to these toxicants have been assessed with the use of antioxidants. The present review focuses on mechanism of lead- and cadmium-induced oxidate damages and the ameliorative measures to counteract the oxidative damage and pathotoxicity with the use of supplemented antioxidants for their beneficial effects.
