    Full Text Available Abstract Background Neurotoxicity is a recognized complication of cyclosporine A (CSA treatment. The incidence of severe CSA-related neurological complications following hematopoietic stem cell transplantation (HSCT is 4-11%. Methods We describe 6 cases of CSA related neurotoxicity out of 67 matched related HSCT performed in paediatric Middle East patients affected by haemoglobinopaties (5 beta thalassemia major, 1 sickle cell disease-SCD. Conditioning regimen consisted of iv busulphan, cyclophosphamide and graft-versus-host-disease (GvHD prophylaxis with CSA, methylprednisolone, methotrexate and ATG. Results All 6 patients presented prodromes such as arterial hypertension, headache, visual disturbances and vomiting, one to two days before overt CSA neurotoxicity. CSA neurotoxicity consisted of generalized seizures, signs of endocranial hypertension and visual disturbances at a median day of onset of 11 days after HSCT (range +1 to +40. Brain magnetic resonance imaging (MRI performed in all subjects showed reversible leukoencephalopathy predominantly in the posterior regions of the brain (PRES in 5/6 patients. EEG performed in 5/6 patients was always abnormal. Neurotoxicity was not explainable by high CSA blood levels, as all patients had CSA in the therapeutic range with a median of 178 ng/ml (range 69-250. CSA was promptly stopped and switched to tacrolimus with disappearance of clinical and radiological findings. All patients are symptoms-free at a median follow up of 882 days (range 60-1065. Conclusions Our experience suggests that paediatric patients with haemoglobinopaties have a high incidence of CSA related neurological events with no correlation between serum CSA levels and neurotoxicity. Prognosis is good following CSA removal. Specific prodromes such as arterial hypertension, headache or visual disturbances occurring in the early post-transplant period should be carefully evaluated with electrophysiological and MRI-based imaging in

    We examined the influences of acute lung injury and hypoxia on neurological outcome. Functional performance was assessed using a neurocognitive test and a neurologic deficit score (NDS) five days before. On experimental day, mechanically ventilated pigs were randomized to hypoxia only (HO group, n=5) or to acute lung injury (ALI group, n=5). Hemodynamics, respiratory mechanics, systemic cytokines and further physiologic variables were obtained at baseline, at the time of ALI, 2, 4 and 8h thereafter. Subsequently, injured lungs were recruited and animals weaned from the ventilator. Neurocognitive testing was re-examined for five days. Then, brains were harvested for neurohistopathology. After the experiment, neurocognitive performance was significantly worsened and the NDS increased in the ALI group. Histopathology revealed no significant differences. Oxygenation was comparable between groups although significantly higher inspiratory pressures occured after ALI. Cytokines showed a trend towards higher levels after ALI. Neurocognitive compromise after ALI seems due to a more pronounced inflammatory response and complex mechanical ventilation.

    Full Text Available Background: The neurologic examination is a challenging component of the physical examination for medical students. In response, primarily based on expert consensus, medical schools have supplemented their curricula with standardized patient (SP sessions that are focused on the neurologic examination. Hypothesis-driven quantitative data are needed to justify the further use of this resource-intensive educational modality, specifically regarding whether using SPs to teach the neurological examination effects a long-term benefit on the application of neurological examination skills. Methods: This study is a cross-sectional analysis of prospectively collected data from medical students at Weill Cornell Medical College. The control group (n=129 received the standard curriculum. The intervention group (n=58 received the standard curriculum and an additional SP session focused on the neurologic examination during the second year of medical school. Student performance on the neurologic examination was assessed in the control and intervention groups via an OSCE administered during the fourth year of medical school. A Neurologic Physical Exam (NPE score of 0.0 to 6.0 was calculated for each student based on a neurologic examination checklist completed by the SPs during the OSCE. Composite NPE scores in the control and intervention groups were compared with the unpaired t-test. Results: In the fourth year OSCE, composite NPE scores in the intervention group (3.5±1.1 were statistically significantly greater than those in the control group (2.2±1.1 (p<0.0001. Conclusions: SP sessions are an effective tool for teaching the neurologic examination. We determined that a single, structured SP session conducted as an adjunct to our traditional lectures and small groups is associated with a statistically significant improvement in student performance measured 2 years after the session.

    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.

  7. Association between neurological assessment and developmental outcome in preterm toddlers

    Jana Kodrič


    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.

  8. Neurologic long term outcome after drowning in children

    Directory of Open Access Journals (Sweden)

    Suominen Pertti K


    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.

  9. Peritoneal dialysis and neurological outcome in infants and small children


    Laakkonen, Hanne


    Although improved outcomes for children on peritoneal dialysis (PD) have been seen in recent years, the youngest patients continue to demonstrate inferior growth, more frequent infections, more neurological sequelae, and higher mortality compared to older children. Also, maintain-ing normal intravascular volume status, especially in anuric patients, has proven difficult. This study was designed to treat and monitor these youngest PD patients, which are relatively many due to the high pre...

    Objective To evaluate the efficacy and safety of repeated low‐dose human recombinant erythropoietin (rhEPO) in the improvement of neurological outcomes in very preterm infants. Methods A total of 800 infants of ≤32‐week gestational age who had been in an intensive care unit within 72 hours after birth were included in the trial between January 2009 and June 2013. Preterm infants were randomly assigned to receive rhEPO (500IU/kg; n = 366) or placebo (n = 377) intravenously within 72 hours after birth and then once every other day for 2 weeks. The primary outcome was death or moderate to severe neurological disability assessed at 18 months of corrected age. Results Death and moderate/severe neurological disability occurred in 91 of 338 very preterm infants (26.9%) in the placebo group and in 43 of 330 very preterm infants (13.0%) in the rhEPO treatment group (relative risk [RR] = 0.40, 95% confidence interval [CI] = 0.27–0.59, p < 0.001) at 18 months of corrected age. The rate of moderate/severe neurological disability in the rhEPO group (22 of 309, 7.1%) was significantly lower compared to the placebo group (57 of 304, 18.8%; RR = 0.32, 95% CI = 0.19–0.55, p < 0.001), and no excess adverse events were observed. Interpretation Repeated low‐dose rhEPO treatment reduced the risk of long‐term neurological disability in very preterm infants with no obvious adverse effects. Ann Neurol 2016;80:24–34 PMID:27130143

    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.)

    Mussa, Firas F; Aaronson, Nicole; Lamparello, Patrick J; Maldonado, Thomas S; Cayne, Neal S; Adelman, Mark A; Riles, Thomas S; Rockman, Caron B


    We reviewed our experience with urgent carotid intervention in the setting of acute neurological deficits. Between June 1992 and August 2008, a total of 3145 carotid endarterectomies (CEA) were performed. Twenty-seven patients (<1.0%) were categorized as urgent. The mean age was 74.1 years (range 56-93 years) with 16 (60%) men, and 11 (40%) women, Symptoms included extremity weakness or paralysis (n=13), amaurosis fugax (n=6), speech difficulty (n=2), and syncope, (n=3). Three patients exhibited a combination of these symptoms. Three open thrombectomy were performed. Regional anesthesia was used in 13 patients (52%). Seventeen patients (67%), required shunt placement. At 30-days, 2 patient (7%) suffered a stroke, and 1 (4%) died. Urgent CEA can be performed safely. A stroke rate of 7% is acceptable in those who may otherwise suffer a dismal outcome without intervention.

    The disabling pathophysiologic effects of lipid and neuroprotective effects of statins have recently been demonstrated for acute spinal cord injuries in animal models. This large scale population-based study aimed to investigate the effect hyperlipidemia and the use of statins in patients with lumbar spine injury. The National Health Insurance Research Database of Taiwan was used to identify patients with lumbar spine injury. A total of 2844 patients were grouped into three: no hyperlipidemia, hyperlipidemia using low-dose of statins (≤90 of the defined daily dosage (DDD)), and severe hyperlipidemia using high-dose of statins (>90 DDD). A Cox multiple regression model was used to compare the incidence rates of disability among the three groups. The results showed that patients with hyperlipidemia appeared a higher risk of permanent disability (adjusted HR = 1.38, p = 0.28). In subgroup analysis, patients with severe hyperlipidemia had a higher risk of disability (adjusted HR = 3.1, p hyperlipidemia using low-dose statins had a similar risk of permanently disability (adjusted HR = 0.83, p = 0.661). Hyperlipidemia adversely affected the neurological outcomes of lumbar spinal injury. Statins may have the potential to reverse this higher risk of disability. However, this beneficiary effect of statins only existed in patients using a lower dose (≤90 DDD).

  16. Association between Body Temperature Patterns and Neurological Outcomes after Extracorporeal Cardiopulmonary Resuscitation (United States)

    Ryu, Jeong-Am; Park, Taek Kyu; Chung, Chi Ryang; Cho, Yang Hyun; Sung, Kiick; Suh, Gee Young; Lee, Tae Rim; Sim, Min Seob; Yang, Jeong Hoon


    We evaluated the association of body temperature patterns with neurological outcomes after extracorporeal cardiopulmonary resuscitation (ECPR). Between December 2013 and December 2015, we enrolled 48 patients with cardiac arrest who survived for at least 24 hours after ECPR. Based on their body temperature patterns and the intention to control fever, we divided the patients into those in whom fever was actively controlled (N = 25), those with normothermia (N = 17), and those with unintended hypothermia (N = 6). The primary outcome was the Cerebral Performance Categories (CPC) scale at discharge. Of the 48 ECPR patients, 23 patients (47.9%) had good neurological outcomes (CPC 1 and 2) and 27 patients (56.3%) survived to discharge. The normothermia group showed a pattern of higher temperatures compared with the other groups during 48 hours after ECPR. Not only poor neurological outcomes but also intensive care unit (ICU) mortality occurred more often in the unintended hypothermia group than in the other two groups, regardless of the fever control strategy (p = 0.023 and p = 0.002, respectively). There were no differences in neurological outcomes and ICU mortality between the actively controlled fever group and the normothermia group (p = 0.845 and p = 0.616, respectively). Unintentionally sustained hypothermia may be associated with poor neurological outcomes after ECPR. These findings suggest that patients who are unable to generate a fever following ECPR may incur severe hypoxic brain injury. PMID:28114337

  17. The Neurological Outcome Scale for Traumatic Brain Injury (NOS-TBI): I. Construct validity. (United States)

    Wilde, Elisabeth A; McCauley, Stephen R; Kelly, Tara M; Weyand, Annie M; Pedroza, Claudia; Levin, Harvey S; Clifton, Guy L; Schnelle, Kathleen P; Shah, Monika V; Moretti, Paolo


    The Neurological Outcome Scale for Traumatic Brain Injury (NOS-TBI) is a measure adapted from the National Institutes of Health Stroke Scale (NIHSS), and is intended to capture essential neurological deficits impacting individuals with traumatic brain injury (TBI) (see Wilde et al., 2010 ). In the present study we evaluate the measure's construct validity via comparison with a quantified neurological examination performed by a neurologist. Spearman rank-order correlation between the NOS-TBI and the neurological examination was rho = 0.76, p TBI compared favorably to the neurological examination items, with correlations ranging from 0.60 to 0.99 (all p TBI, and on the NOS-TBI neurological impairment was evident in all but one participant. This study documents the presence of measurable neurological sequelae in a sample of patients with TBI in a post-acute rehabilitation setting, underscoring the need for formal measurement of the frequency and severity of neurological deficits in this population. The results suggest that the NOS-TBI is a valid measure of neurological functioning in patients with TBI.

    Patrick Mulligan


    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.

  1. Neurologic Outcomes in Very Preterm Infants Undergoing Surgery.

    LENUS (Irish Health Repository)


    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.

    Mauro Dobran


    Full Text Available Background: Traumatic thoracolumbar spinal fractures represent approximately 65% of all traumatic spinal fractures and are frequently associated to permanent disability with significant social and economic impact. These injuries create severe physical limitations depending on neurological status, level of fracture, severity of injury, patient age and comorbidities. Predicting neurological improvement in patients with traumatic spinal cord injuries (SCIs is very difficult because it is related to different preoperative prognostic factors. We evaluated the neurological improvement related to the preoperative neurological conditions and the anatomic level of spinal cord injury. Methods: From January 2004 to June 2010, we operated 207 patients for unstable thoracolumbar spinal fractures. We carried out a retrospective analysis of 69 patients with traumatic SCIs operated on by a posterior fixation performed within 24 hours from the trauma. The preoperative neurological conditions (ASIA grade, the type of the fracture, the anatomic level of spinal cord injury and the postoperative neurological improvement were evaluated for each patient. Results: The ASIA grade at admission (P = 0,0005, the fracture type according to the AO spine classification (P = 0,0002, and the anatomic location of the injury (P = 0,0213 represented predictive factors of neurological improvement at univariate analysis. The preoperative neurological status (P = 0,0491 and the fracture type (P = 0,049 confirmed a positive predictive value also in the multivariate analysis. Conclusions : Our study confirms that the preoperative neurological status, the fracture type and the anatomic location of the fracture are predictive factors of the neurological outcome in patients with spinal cord injury.

    Bosson, Nichole E; Kaji, Amy H; Koenig, William J; Niemann, James T


    Old age is considered a negative prognostic factor after out-of-hospital cardiac arrest (OHCA). The purpose of this study was to assess the benefit of therapeutic hypothermia (TH) on survival and neurologic outcome in the elderly. This is a retrospective study of patients treated for OHCA from April 2011 to August 2013 in a regional cardiac system. Patients with return of spontaneous circulation (ROSC) are directed to designated cardiac receiving centers with established TH protocols. The decision to initiate TH is determined by the treating physician. All patients 65 years or older were identified. Patients were excluded if awake and responsive in the emergency department, died before hospital admission, or had preexisting coma. The adjusted odds ratio for survival with good neurologic outcome (defined as cerebral performance category [CPC] 1 or 2) was calculated for patients who received TH compared to a reference group without TH. There were 1612 patients, of whom 552 (34%) received TH. Median age was 78 (inter-quartile range [IQR] 71-85); 56% was male. 493 (31%) patients survived to hospital discharge, 266 (17%) with CPC of 1 or 2. Of 1292 patients considered for TH, 192 (25%) of 552 patients who received TH survived to hospital discharge and 97 (18%) with good neurologic outcome compared to 150 (20%) and 57 (8%), respectively, without TH. The adjusted odds ratio for survival with good neurologic outcome for TH was 2.0 (95% CI 1.3-3.3). TH is associated with improved neurologic outcome in the elderly population.

    A number of observational studies have evaluated the association between arterial oxygen tensions and outcome after cardiac arrest with variable results. The objective of this study is to determine the association between arterial oxygen tension and neurological outcome after cardiac arrest. A retrospective cohort analysis was performed using the Penn Alliance for Therapeutic Hypothermia registry. Adult patients who experienced return of spontaneous circulation after in-hospital or out-of-hospital cardiac arrest (OHCA) and had a partial pressure of arterial oxygen (PaO2) recorded within 48 hours were included. Our primary exposure of interest was PaO2. Hyperoxemia was defined as PaO2 > 300 mmHg, hypoxemia as PaO2 arterial oxygen tension measured within the first 48 hours after cardiac arrest and neurological outcome.

    Malheiros Suzana M. F.


    Full Text Available Coronary artery bypass surgery (CABG without cardiopulmonary bypass (CPB may potentially reduce the number of microembolic signals (MES associated with aortic manipulation or generated by the pump circuit, resulting in a better neurologic outcome after surgery. Our aim was to compare the frequency of MES and neurologic complications in CABG with and without CPB. Twenty patients eligible to routine CABG without CPB were randomized to surgery with CPB and without CPB and continuously monitored by transcranial Doppler. Neurologic examination was performed in all patients before and after surgery. The two groups were similar with respect to demographics, risk factors, grade of aortic atheromatous disease and number of grafts. The frequency of MES in the nonCPB group was considerably lower than in CPB patients, however, we did not observe any change in the neurologic examination during the early postoperative period. Neurologic complications after CABG may be related to the size and composition of MES rather than to their absolute numbers. A large prospective multicentric randomized trial may help to elucidate this complex issue.

    Full Text Available BACKGROUND: Neonates with bacteremia are at risk of neurologic complications. Relevant information warrants further elucidation. STUDY DESIGN: This was a retrospective cohort study of neonates with bacteremia-related neurologic complications (BNCs in a tertiary-level neonatal intensive care unit (NICU. A systemic chart review was performed conducted to identify clinical characteristics and outcomes. A cohort of related conditions was constructed as the control group. Logistic regression analysis was used to identify independent risk factors for BNC. RESULTS: Of 1037 bacteremia episodes, 36 (3.5% had BNCs. Twenty-four cases of BNCs were related to meningitis, five were presumed meningitis, and seven occurred after septic shock. The most common causative pathogens were Group B streptococcus (41.7% and E. coli (16.7%. The major BNCs consisted of seizures (28, hydrocephalus (20, encephalomalacia (11, cerebral infarction (7, subdural empyema (6, ventriculitis (8, and abscess (4. Eight (22.8% neonates died and six (16.7% were discharged in critical condition when the family withdrew life-sustaining treatment. Among the 22 survivors, eight had neurologic sequelae upon discharge. After multivariate logistic regression analysis, neonates with meningitis caused by Group B streptococcus (adjusted odds ratio [OR]: 8.90, 95% confidence interval [CI]: 2.20-36.08; p = 0.002 and combined meningitis and septic shock (OR, 5.94; 95% CI: 1.53-23.15; p = 0.010 were independently associated with BNCs. CONCLUSIONS: Neonates with bacteremia-related neurologic complications are associated with adverse outcomes or sequelae. Better strategies aimed at early detection and reducing the emergence of neurologic complications and aggressive treatment of Group B streptococcus sepsis are needed in neonates with meningitis and septic shock.

    Objective. Previously, we demonstrated that remote ischemic postconditioning (RIpostC) improved postresuscitation myocardial and cerebral functions in rat. Here, we investigated the effects of RIpostC alone and combined with therapeutic hypothermia (TH) on cardiac and neurological outcomes after CPR in swine. Methods. Twenty-one pigs were subjected to 10 mins of VF and then 5 mins of CPR. The animals were randomized to receive RIpostC alone, or its combination with TH, or sham control. RIpostC was induced by 4 cycles of limb ischemia followed by reperfusion. TH was implemented by surface cooling to reach a temperature of 32-34°C. Results. During 72 hrs after resuscitation, lower level of cardiac troponin I and greater stroke volume and global ejection fraction were observed in animals that received RIpostC when compared to the control. RIpostC also decreased serum levels of neuron-specific enolase and S100B and increased neurologic alertness score after resuscitation. The combination of RIpostC and TH resulted in greater improvement in cardiac and neurological outcomes than RIpostC alone. Conclusion. RIpostC was conducive to improving postresuscitation myocardial and cerebral functions and reducing their organ injuries. Its combination with TH further enhanced its protective effects.

    A standardized measure of neurological dysfunction specifically designed for TBI currently does not exist and the lack of assessment of this domain represents a substantial gap. To address this, the Neurological Outcome Scale for Traumatic Brain Injury (NOS-TBI) was developed for TBI outcomes research through the addition to and modification of items specifically relevant to patients with TBI, based on the National Institutes of Health Stroke Scale. In a sample of 50 participants (mean age = 33.3 years, SD = 12.9) TBI, internal consistency of the NOS-TBI was high (Cronbach's alpha = 0.942). Test-retest reliability also was high (rho = 0.97, p TBI total score was excellent (W = 0.995). Convergent validity was demonstrated through significant Spearman rank-order correlations between the NOS-TBI and the concurrently administered Disability Rating Scale (rho = 0.75, p TBI is a reliable and valid measure of neurological functioning in patients with moderate to severe TBI.

    Full Text Available Context: The use of biomarkers to predict stroke prognosis is gaining particular attention nowadays. Neuron specific enolase (NSE, which is a dimeric isoenzyme of the glycolytic enzyme enolase and is found mainly in the neurons is one such biomarker. Aims: This study was carried out on patients of acute ischemic stroke with the aims to determine the correlation between NSE levels on the day of admission with infarct volume, stroke severity, and functional neurological outcome on day 30. Materials and Methods: Seventy five patients of acute ischemic stroke admitted in the Department of Medicine were included in the study. Levels of NSE were determined on day 1 using the human NSE ELISA kit (Alpha Diagnostic International Texas 78244, USA. Volume of infarct was measured by computed tomography (CT scan using the preinstalled software Syngo (version A40A of Siemen′s medical solutions (Forchheim, Germany. Stroke severity at admission was assessed using Glasgow coma scale (GCS and functional neurological outcome was assessed using modified Rankin scale (mRS on day 30. Statistical Analysis Used: Statistical analysis was performed using the SPSS software for windows version 15.0 (SPSS. Results: A positive correlation was found between concentration of NSE on day 1 and infarct volume determined by CT scan (r = 0.955, P < 0.001. A strong negative correlation was found between GCS at presentation and concentration of NSE on day 1 (r = −0.806, P < 0.001. There was a positive correlation between NSE levels at day 1 and functional neurological outcome assessed by mRS at day 30 (r = 0.744, P < 0.001. Conclusions: Serum levels of NSE in first few days of ischemic stroke can serve as a useful marker to predict stroke severity and early functional outcome. However, larger studies with serial estimation of NSE are needed to establish these observations more firmly.

    Full Text Available OBJECTIVES: Our aim was to evaluate the relationship between serum C-reactive protein (CRP levels and the neurological prognosis and development of vasospasm in patients with aneurysmal subarachnoid hemorrhage (aSAH. METHODS: Eighty-two adult patients with aSAH diagnoses were prospectively evaluated. Glasgow Coma Scale (GCS score, Hunt and Hess grade, Fisher grade, cranial CT scans, digital subtraction angiography studies and daily neurological examinations were recorded. Serial serum CRP measurements were obtained daily between admission and the tenth day. Glasgow Outcome Scale (GOS and the modified Rankin Scale (mRS were used to assess the prognosis. RESULTS: Serum CRP levels were related to severity of aSAH. Patients with lower GCS scores and higher Hunt and Hess and Fisher grades presented statistically significant higher serum CRP levels. Patients with higher serum CRP levels had a less favorable prognosis. CONCLUSIONS: Increased serum CRP levels were strongly associated with worse clinical prognosis in this study.

    Gupta, Anupam; Kumar, Sushruth Nagesh; Taly, Arun B.


    Objective: The objective of this study was to observe urodynamic profile of acute transverse myelitis (ATM) patients and its correlation with neurological outcome. Patients and Methods: This prospective study was conducted in the neurorehabilitation unit of a tertiary university research hospital from July 2012 to June 2014. Forty-three patients (19 men) with ATM with bladder dysfunction, admitted in the rehabilitation unit, were included in this study. Urodynamic study (UDS) was performed in all the patients. Their neurological status was assessed using ASIA impairment scale and functional status was assessed using spinal cord independence measure. Bladder management was based on UDS findings. Results: In total, 17 patients had tetraplegia and 26 had paraplegia. Thirty-six patients (83.7%) had complaints of increased frequency and urgency of urine with 26 patients reported at least one episode of urge incontinence. Seven patients reported obstructive urinary complaints in the form of straining to void with 13 patients reported both urgency and straining to void and 3 also had stress incontinence. Thirty-seven (86.1%) patients had neurogenic overactive detrusor with or without sphincter dyssynergia and five patients had acontractile detrusor on UDS. No definitive pattern was observed between neurological status and bladder characteristics. All patients showed significant neurological and functional recovery with inpatient rehabilitation (P < 0.05 and P < 0.001, respectively). Conclusions: The problem of neurogenic bladder dysfunction is integral to ATM. Bladder management in these patients should be based on UDS findings. Bladder characteristics have no definitive pattern consistent with the neurological status. PMID:28149080

    Ismail, Ahmed A; Bonner, Matthew R; Hendy, Olfat; Abdel Rasoul, Gaafar; Wang, Kai; Olson, James R; Rohlman, Diane S


    Pesticide-exposed adolescents may have a higher risk of neurotoxic effects because of their developing brains and bodies. However, only a limited number of studies have addressed this risk among adolescents. The aim of this study was to compare neurological outcomes from two cohorts of Egyptian adolescents working as pesticide applicators. In 2005 and 2009, two cohorts of male adolescents working as pesticide applicators for the cotton crop were recruited from Menoufia Governorate, Egypt. The same application schedule and pesticides were used at both times, including both organophosphorus, and pyrethroid compounds. Participants in both cohorts completed three neurobehavioral tests, health and exposure questionnaires, and medical and neurological screening examinations. In addition, blood samples were collected to measure butyryl cholinesterase (BChE) activity. Pesticide applicators in both cohorts reported more neurological symptoms and signs than non-applicators, particularly among participants in the 2005 cohort (OR ranged from 1.18 to 15.3). Except for one test (Trail Making B), there were no significant differences between either applicators or non-applicators of both cohorts on the neurobehavioral outcome measures (p > 0.05). The 2005 cohort showed greater inhibition of serum BChE activity than the 2009 cohort (p < 0.05). In addition, participants with depressed BChE activity showed more symptoms and signs than others without BChE depression (p < 0.05). Our study is the first to examine the consistency of health outcomes associated with pesticide exposure across two cohorts tested at different times from the same geographical region in rural Egypt. This similar pattern of findings across the two cohorts provides strong evidence of the health impact of exposure of adolescents to pesticides.

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.

  19. The placenta and neurologic and psychiatric outcomes in the child: study design matters. (United States)

    Nelson, K B; Blair, E


    Much information exists about functions of the human placenta and about potential mechanisms by which the placenta may influence human health or disease, including developmental disorders of brain. Recent studies indicate a high frequency of placental pathology in infants with developmental brain disorders, or with risk factors for such disorders. However, most clinical studies of the association of placental features with adverse neurologic or psychiatric outcome have substantial methodologic limitations. We discuss issues of study design as they relate to studies of the placenta and human brain disorders. In addition to the need for further consensus on procedures and terminology for placental evaluation, there are a number of special features that make clinical studies of the association of placental features with neurologic and psychiatric disorders especially difficult: most such disorders are not diagnosed until months or years after the majority of placentas have been discarded; these disorders are individually uncommon, so that prospective studies - needed to provide denominator data to enable estimation of risks - will require very large sample sizes; the administrative structures required to relate features of the placenta with clinical outcome will be complicated and costly. We offer some suggestions concerning study design in the face of these practical difficulties. Systematic and methodologically rigorous exploration of the role of the placenta in human developmental brain disorders has scarcely begun. A new generation of studies, difficult but potentially enormously rewarding, will be needed for clinical investigations of the placenta and fetal brain development.

    Toxic oil syndrome (TOS) resulted from consumption of rapeseed oil denatured with 2% aniline and affected more than 20,000 persons. Eighteen years after the epidemic, many patients continue to report neurologic symptoms that are difficult to evaluate using conventional techniques. We conducted an epidemiologic study to determine whether an exposure to toxic oil 18 years ago was associated with current adverse neurobehavioral effects. We studied a case group of 80 adults exposed to toxic oil 18 years ago and a referent group of 79 adult age- and sex-frequency-matched unexposed subjects. We interviewed subjects for demographics, health status, exposures to neurotoxicants, and responses to the Kaufman Brief Intelligence Test (K-BIT), Programa Integrado de Exploracion Neuropsicologica (PIEN), and Goldberg depression questionnaires and administered quantitative neurobehavioral and neurophysiologic tests by computer or trained nurses. The groups did not differ with respect to educational background or other critical variables. We examined associations between case and referent groups and the neurobehavioral and neurophysiologic outcomes of interest. Decreased distal strength of the dominant and nondominant hands and increased vibrotactile thresholds of the fingers and toes were significantly associated with exposure to toxic oil. Finger tapping, simple reaction time latency, sequence B latency, symbol digit latency, and auditory digit span were also significantly associated with exposure. Case subjects also had statistically significantly more neuropsychologic symptoms compared with referents. Using quantitative neurologic tests, we found significant adverse central and peripheral neurologic effects in a group of TOS patients 18 years after exposure to toxic oil when compared with a nonexposed referent group. These effects were not documented by standard clinical examination and were found more frequently in women.

  1. Predictive value of sequential electroencephalogram (EEG) in neonates with seizures and its relation to neurological outcome. (United States)

    Khan, Richard Lester; Nunes, Magda Lahorgue; Garcias da Silva, Luis Fernando; da Costa, Jaderson Costa


    The aim of this study was to evaluate the relationship of sequential neonatal electroencephalography (EEG) and neurological outcome in neonates with seizures to identify polysomnographic features predictive of outcome. Sequential EEGs recordings of 58 neonates that belonged to 2 historical cohorts of newborns with seizures from the same neonatal intensive care unit and who had follow-up at the Neurodevelopment Clinic of the Hospital São Lucas, Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS) in Porto Alegre, Brazil, were analyzed and classified into 4 groups: normal-normal, abnormal-normal, abnormal-abnormal, normal-abnormal. In patients with more than 2 recordings, during the neonatal period, the first EEG was compared with the following more abnormal. A total of 58 pairs of 2 sequential EEGs were analyzed. Considering the first EEG, a statistically significant difference was observed between the relationship of the result of this exam, if it was abnormal, with developmental delay (P = .030) and postnatal death (P = .030). Abnormal background activity was also related to neurodevelopment delay (P = .041). EEG sequences abnormal-abnormal and normal-abnormal significantly correlated to the outcome epilepsy ( P = .015). Abnormal sequential background activity was associated with neurodevelopment delay (P = .006) and epilepsy (P = .041). The burst suppression pattern when present in any EEG correlated with epilepsy (P = .013) and postnatal death (P = .034). Sequential abnormal background patterns in the first and second EEG increased the risk for epilepsy (relative risk [RR] = 1.8; 95% confidence interval [CI] = 1.03-3.0) and neurodevelopment delay (RR = 2.20; 95% CI = 1.3-3.0). Abnormal background activity only in the second electroencephalogram increased the risk for neurodevelopment delay (RR = 2.20; 95% CI = 1.3-3.0). All the neonates (n = 33) with seizures related to probable hypoxic ischemic encephalopathy had abnormalities in the first EEG (P

  2. Image-guided Spine Stabilization for Traumatic or Osteoporotic Spine Injury: Radiological Accuracy and Neurological Outcome (United States)

    SHIMOKAWA, Nobuyuki; ABE, Junya; SATOH, Hidetoshi; ARIMA, Hironori; TAKAMI, Toshihiro


    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.

    This investigation describes the relationship between TBI patient demographics, quality of life outcome, and functional status outcome among clinic attendees and non-attendees. Of adult TBI survivors with intracranial hemorrhage, 63 attended our TBI clinic and 167 did not attend. All were telephone surveyed using the Extended-Glasgow Outcome Scale (GOSE), the Quality of Life after Brain Injury (QOLIBRI) scale, and a post-discharge therapy questionnaire. To determine risk factors for GOSE and QOLIBRI outcomes, we created multivariable regression models employing covariates of age, injury characteristics, clinic attendance, insurance status, post-discharge rehabilitation, and time from injury. Compared with those with severe TBI, higher GOSE scores were identified in individuals with both mild (odds ratio [OR]=2.0; 95% confidence interval [CI]: 1.1-3.6) and moderate (OR=4.7; 95% CI: 1.6-14.1) TBIs. In addition, survivors with private insurance had higher GOSE scores, compared with those with public insurance (OR=2.0; 95% CI: 1.1-3.6), workers' compensation (OR=8.4; 95% CI: 2.6-26.9), and no insurance (OR=3.1; 95% CI: 1.6-6.2). Compared with those with severe TBI, QOLIBRI scores were 11.7 points (95% CI: 3.7-19.7) higher in survivors with mild TBI and 17.3 points (95% CI: 3.2-31.5) higher in survivors with moderate TBI. In addition, survivors who received post-discharge rehabilitation had higher QOLIBRI scores by 11.4 points (95% CI: 3.7-19.1) than those who did not. Survivors with private insurance had QOLIBRI scores that were 25.5 points higher (95% CI: 11.3-39.7) than those with workers' compensation and 16.8 points higher (95% CI: 7.4-26.2) than those without insurance. Because neurologic injury severity, insurance status, and receipt of rehabilitation or therapy are independent risk factors for functional and quality of life outcomes, future directions will include improving earlier access to post-TBI rehabilitation, social work services, affordable insurance

  5. Intracerebral adenosine infusion improves neurological outcome after transient focal ischemia in rats. (United States)

    Kitagawa, Hisashi; Mori, Atsushi; Shimada, Jun; Mitsumoto, Yasuhide; Kikuchi, Tetsuro


    Second Institute of New Drug Research, Otsuka Pharmaceutical Co., Ltd., Tokushima, Japan In order to elucidate the role of adenosine in brain ischemia, the possible protective effects of adenosine on ischemic brain injury were investigated in a rat model of brain ischemia both in vitro and in vivo. Exogenous adenosine dose-dependently rescued cortical neuronal cells from injury after glucose deprivation in vitro. Adenosine (1 mM) also significantly reduced hypoglycemia/hypoxia-induced glutamate release from the hippocampal slice. In a rat model of transient middle cerebral artery occlusion (MCAO), extracellular adenosine concentration was increased immediately after occlusion, and then returned to the baseline by 30 min after reperfusion. Adenosine infusion through a microdialysis probe into the ipsilateral striatum (1 mM adenosine, 2 microl min(-1), total 4.5 h from the occlusion to 3 h after reperfusion) showed a significant improvement in the neurological outcome, and about 25% reduction of infarct volume, although the effect did not reach statistical significance, compared with the vehicle-treated group at 20 h after 90 min of MCAO. These results demonstrated the neuroprotective effect of adenosine against ischemic brain injury both in vitro and in vivo, suggesting the possible therapeutic application of adenosine regulating agents, which inhibit adenosine uptake or metabolism to enhance or maintain extracellular endogenous adenosine levels, for stroke treatment.

    Full Text Available ABSTRACT Hematopoietic stem cell transplantation (HSCT is the only available treatment for the neurological involvement of disorders such as late-onset metachromatic leukodystrophy (MLD, mucopolysaccharidosis type I-Hurler (MPS-IH, and X-linked cerebral adrenoleukodystrophy (CALD. Objective To describe survival and neurological outcomes after HSCT for these disorders. Methods Seven CALD, 2 MLD and 2 MPS-IH patients underwent HSCT between 2007 and 2014. Neurological examinations, magnetic resonance imaging, molecular and biochemical studies were obtained at baseline and repeated when appropriated. Results Favorable outcomes were obtained with 4/5 related and 3/6 unrelated donors. Two patients died from procedure-related complications. Nine transplanted patients were alive after a median of 3.7 years: neurological stabilization was obtained in 5/6 CALD, 1/2 MLD, and one MPS-IH patient. Brain lesions of the MPS-IH patient were reduced four years after HSCT. Conclusion Good outcomes were obtained when HSCT was performed before adulthood, early in the clinical course, and/or from a related donor.

  10. A fusion protein composed of IL-2 and caspase-3 ameliorates the outcome of experimental inflammatory colitis. (United States)

    Sagiv, Yuval; Kaminitz, Ayelet; Lorberboum-Galski, Haya; Askenasy, Nadir; Yarkoni, Shai


    Targeted depletion of immune cells expressing the interleukin-2 (IL-2) receptor can exacerbate inflammatory bowel disease (IBD) through elimination of regulatory T (Treg) cells, or ameliorate its course by depletion of cytotoxic cells. To answer this question we used a fusion protein composed of IL-2 and caspase-3 (IL2-cas) in an experimental model of DSS-induced toxic colitis. In a preventive setting, co-administration of DSS with a daily therapeutic dose of IL2-cas for seven days improved all disease parameters. Although CD4(+)CD25(+) T cells were depleted in the mesenteric lymph nodes, a fractional increase in CD4(+)FoxP3(+) T cells was observed in the spleen. Likewise, IL2-cas therapy improved the outcome of established disease in a chronic model of colitis. These data demonstrate that therapies that use IL-2 as a targeting moiety exert a protective effect over the colon under conditions of inflammation. The efficacy of IL-2-targeted therapy is attributed to reduced activity of reactive T cells, which ameliorates the secondary inflammatory infiltration. IL2-cas evolves as a potential therapeutic tool in IBD.

  11. Neurological and circulatory outcomes of cardiopulmonary resuscitation in progress: influence of pre-arrest and arrest factors. (United States)

    Jørgensen, E O


    Possible correlations between the circulatory and neurological responses to cardiopulmonary resuscitation (CPR) and the influence of pre-arrest factors (demographic data, medical history and aetiology of circulatory arrest) and arrest factors (location of arrest, ECG configurations, and duration of resuscitation) on the course of circulatory and neurological recovery were investigated in 111 victims of circulatory arrest. At the start of resuscitation 57 patients (Group I) had some brain function and 54 (Group II) had no brain function. Sixty nine patients (62%) had circulation restored but 54 (78%) were left with heart failure. Forty one patients (39%) survived the first day, 26 (63%) with heart failure; only 34 (31%) were alive after 48 h, 17 (50%) with heart failure. Half of the patients surviving 24 or 48 h had awakened. Consciousness returned in 32 patients (29%) during the first 48 h, more frequently in Group I than in Group II. Patients in Group I had a higher incidence of in-hospital arrest and had their circulation restored more often than those in Group II. Survival and post-resuscitation heart failure was alike in the groups. The pre-arrest factors explored did not modify the circulatory or neurological outcome whereas initial ventricular fibrillation was significantly related to recovery of consciousness. The revivability of spontaneous circulation and of neurological functions was found thus mainly to be determined by global ischaemia sustained prior to and during CPR.

    We performed a cohort study of children who survived bacterial meningitis after the neonatal period at a single pediatric center in France over a 10-year period (1995-2004) to identify predictors of death and long-term neurological deficits in children with bacterial meningitis. We performed multivariate regression to determine independent predictors of death and neurologic deficits. We identified 101 children with bacterial meningitis of which 19 died during initial hospitalization. Need for mechanical ventilation [hazard ratio (HR) 11.5, 95 % confidence interval (CI) 2.4-55.5)] and thrombocytopenia defined as a platelet count highest risk.

    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.

  19. 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.

  1. Can the Assessment of Spontaneous Oscillations by Near Infrared Spectrophotometry Predict Neurological Outcome of Preterm Infants? (United States)

    Stammwitz, André; von Siebenthal, Kurt; Bucher, Hans U; Wolf, Martin


    The aim was to assess the correlation between cerebral autoregulation and outcome. Included were 31 preterm infants, gestational age 26 1/7 to 32 2/7 and infrared spectrophotometry (NIRS) and systemic heart rate (HR) or arterial blood pressure (MAP) was calculated as a measure of autoregulation. In contrast to previous studies, low coherences in the first 24 h were significantly associated with intraventricular haemorrhage, death or abnormal neurodevelopmental outcome at 18 months or later. We suggest that our results can be explained by the concept of a multi-oscillatory-functions-order.

    Full Text Available Abstract Background Human cytomegalovirus (HCMV infection of the central nervous system (CNS is a rare but life threatening condition which may follow hematopoietic stem cell transplantation. Diagnosis, monitoring and treatment approaches rely on anecdotal reports. Case presentations The different outcomes of HCMV CNS disease in an adult and a pediatric T-cell depleted hematopoietic stem cell transplant (HSCT recipient are reported. In the first case, HCMV encephalitis emerged in the context of simultaneous impairment of the T- and B-cell immunity. Antiviral treatment only reduced viral load in peripheral blood and the patient died. In the second case, an HCMV radiculopathy was observed and antiviral treatment was adjusted on the basis of intrathecal drug level. In addition, donor HCMV-specific cytotoxic T lymphocytes (CTLs were infused. Viral load in the CNS decreased and the patient recovered from the acute event. In neither case were drug-resistant HCMV variants observed in blood or CNS samples. Conclusions T-cell depleted HSCT appears a predisposing condition for CNS HCMV infection since never observed in other HSCT recipients at our center in the last 15 years. Intensive diagnostic approaches and timely aggressive combination treatments might improve clinical outcome in these patients.

    Full Text Available Introduction. Clinical picture of severe glyphosatesurfactant poisoning is manifested by gastroenteritis, respiratory disturbances, altered mental status, hypotension refractory to the treatment, renal failure, shock. Single case report indicated possible neurotoxic sequels of glyphosatesurfactant exposure with white matter lesions and development of Parkinsonism. We described a patient with massive white matter damage which led to vigil coma and lethal outcome. Case report. A 56-year old woman ingested about 500 mL of herbicide containing glyphosate isopropylamine salt. The most prominent manifestation of poisoning included hypotension, coma, hyperkaliemia, respiratory and renal failure. The patient was treated in intensive care unit by symptomatic and supportive therapy including mechanical ventilation and hemodialysis. The patient survived the acute phase of poisoning, but she developed vigil coma. Nuclear magnetic imagining revealed extensive bilateral lesions of the brain stem white matter and pons. Conclusion. The outcome of reported poisoning may be the consequence of glyphosate-surfactant neurotoxic effect or/and ischemia, especially in the episodes of marked hypotension during hemodialysis. Considering recommendation of early hemodialysis as the treatment of choice, even before renal failure development, we point out the importance of careful planning of dialysis modality in hemodynamically instable patient and recommend continuous dialysis methods.

  5. Memory outcomes following cognitive interventions in children with neurological deficits: A review with a focus on under-studied populations. (United States)

    Schaffer, Yael; Geva, Ronny


    Given the primary role of memory in children's learning and well-being, the aim of this review was to examine the outcomes of memory remediation interventions in children with neurological deficits as a function of the affected memory system and intervention method. Fifty-seven studies that evaluated the outcome of memory interventions in children were identified. Thirty-four studies met the inclusion criteria, and were included in a systematic review. Diverse rehabilitation methods for improving explicit and implicit memory in children were reviewed. The analysis indicates that teaching restoration strategies may improve, and result in the generalisation of, semantic memory and working memory performance in children older than 7 years with mild to moderate memory deficits. Factors such as longer protocols, emotional support, and personal feedback contribute to intervention efficacy. In addition, the use of compensation aids seems to be highly effective in prospective memory tasks. Finally, the review unveiled a lack of studies with young children and the absence of group interventions. These findings point to the importance of future evidence-based intervention protocols in these areas.

    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.

    The effects of hyperoxia on the neurological outcomes of patients with severe traumatic brain injury (TBI) are still controversial. We examined whether the partial pressure of arterial oxygen (PaO2) and hyperoxia were associated with neurological outcomes and survival by conducting post-hoc analyses of the Brain Hypothermia (B-HYPO) study, a multi-center randomized controlled trial of mild therapeutic hypothermia for severe TBI. The differences in PaO2 and PaO2/fraction of inspiratory oxygen (P/F) ratio on the 1st day of admission were compared between patients with favorable (n = 64) and unfavorable (n = 65) neurological outcomes and between survivors (n = 90) and deceased patients (n = 39). PaO2 and the P/F ratio were significantly greater in patients with favorable outcomes than in patients with unfavorable neurological outcomes (PaO2: 252 ± 122 vs. 202 ± 87 mm Hg, respectively, p = 0.008; P/F ratio: 455 ± 171 vs. 389 ± 155, respectively, p = 0.022) and in survivors than in deceased patients (PaO2: 242 ± 117 vs. 193 ± 75 mm Hg, respectively, p = 0.005; P/F ratio: 445 ± 171 vs. 370 ± 141, respectively, p = 0.018). Similar tendencies were observed in subgroup analyses in patients with fever control and therapeutic hypothermia, and in patients with an evacuated mass or other lesions (unevacuated lesions). PaO2 was independently associated with survival (odds ratio 1.008, p = 0.037). These results suggested that early-stage hyperoxia might be associated with favorable neurological outcomes and survival following severe TBI.

    Na(+)/Ca2+ exchanger (NCX) is a plasma membrane transporter that, by regulating Ca2+ and Na(+) homeostasis, contributes to brain stroke damage. The objectives of this study were to investigate whether there might be miRNAs in the brain able to regulate NCX1 expression and, thereafter, to set up a valid therapeutic strategy able to reduce stroke-induced brain damage by regulating NCX1 expression. Thus, we tested whether miR-103-1, a microRNA belonging to the miR-103/107 family that on the basis of sequence analysis might be a potential NCX1 regulator, could control NCX1 expression. The role of miR-103-1 was assessed in a rat model of transient cerebral ischemia by evaluating the effect of the correspondent antimiRNA on both brain infarct volume and neurological deficits. NCX1 expression was dramatically reduced when cortical neurons were exposed to miR-103-1. This alleged tight regulation of NCX1 by miR-103-1 was further corroborated by luciferase assay. Notably, antimiR-103-1 prevented NCX1 protein downregulation induced by the increase in miR-103-1 after brain ischemia, thereby reducing brain damage and neurological deficits. Overall, the identification of a microRNA able to selectively regulate NCX1 in the brain clarifies a new important molecular mechanism of NCX1 regulation in the brain and offers the opportunity to develop a new therapeutic strategy for stroke.

  10. Prognose des neurologischen Outcomes nach Herz-Kreislaufstillstand: Macht Temperaturmanagement einen Unterschied? // Prognostication of Neurological Outcome after Cardiac Arrest: Does Hypothermia makes a Difference?

    Directory of Open Access Journals (Sweden)

    Storm C


    Full Text Available Today, most survivors after cardiac arrest will receive a targeted temperature management in the post-resuscitation phase. Early the important question of the neurological prognosis occurs. In addition to the neurological examination (motor response to painful stimuli, brain stem reflexes technical diagnostics are widely used (SEP, EEG, CCT, CMRI. Furthermore, the serum concentration of biomarkers, such as neuron-specific Enolase (NSE in clinical routine and others mainly in the context of research (S-100B, CRP, PCT, micro-RNA are determined. After introduction of targeted temperature management, several studies from different centres have re-evaluated prognostic parameters. Hypothermia likely alters the level of neuron-specific enolase, markedly higher cut-offs apply for patients treated with hypothermia. The prognostic value of median nerve SEP remains largely unchanged. The sedation used during hypothermia renders neurological examination unreliable, even a few days after rewarming the lack of a motor response to painful stimuli does not safely exclude good neurological outcome. In addition, the absence of corneal reflexes is a less reliable parameter than the absence of pupillary light response. Recent studies indicate that evaluation of several prognostic parameters and interpretation in synopsis is advisable. In addition, clinical follow-up over a few days and re-evaluation of prognostic parameters may increase safety of a poor outcome prediction. p bKurzfassung: /bAktuell wird die Mehrzahl der Patienten nach erfolgreicher Reanimation mit einem „Targeted Temperature Management“ in der Post-Reanimationsphase behandelt.

    Ghori, Kamran A


    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.

  12. Predictive Value of Brain Arrest Neurological Outcome Scale (BrANOS) on Mortality and Morbidity After Cardiac Arrest (United States)

    Şahutoğlu, Cengiz; Uyar, Mehmet; Demirağ, Kubilay; İsayev, Hasan; Moral, Ali Reşat


    Objective There are several prediction scales and parameters for prognosis after a cardiac arrest. One of these scales is the brain arrest neurological outcome scale (BrANOS), which consists of duration of cardiac arrest, Glasgow Coma Scale score and Hounsfield unit measured on cranial computed tomography (CT) scan. The objective of this study is to investigate the effectiveness of BrANOS on predicting the mortality and disability after a cardiac arrest. Methods We retrospectively investigated cardiac arrest patients who were hospitalized in our intensive care unit (ICU) within a 3-year period. Inclusion criteria were age over 18 years old, survival of more than 24 hours after cardiac arrest and availability of cranial CT. We recorded the age, sex, diagnosis, duration of cardiac arrest and hospital stay, mortality, Glasgow Outcome Score (GOS) and BrANOS score. The primary endpoint of the study was to establish the relationship between mortality and BrANOS score in patients who survived for more than 24 hours after a cardiac arrest. The secondary endpoint of the study was to determine the 2-year life expectancy and GOS after cardiac arrest. Results The mean age of the patients was 57±17 years (33 females, 67 males). ICU mortality rate was 57%. The BrANOS mean score was 10.3±3.2. There was a significant difference between survivors and non-survivors in terms of the BrANOS score (8.8±3.2 vs. 11.6±2.7; p14 predicted death with 100% accuracy. All the patients without disability had a BrANOS score of <10. The BrANOS score also correlated well with GOS (p<0.001). The 2-year life expectancy rate was 31% in patients who survived more than 24 hours after a cardiac arrest. Conclusion In this study, we demonstrated that BrANOS provided reliable data for prognostic evaluation after a cardiac arrest. PMID:28058140

    Full Text Available To compare the Conventional, Specified, Expanded and Combined Apgar scoring systems in predicting birth asphyxia and the adverse early neurologic outcomes.This prospective cohort study was conducted on 464 admitted neonates. In the delivery room, after delivery the umbilical cord was double clamped and a blood samples was obtained from the umbilical artery for blood gas analysis, meanwhile on the 1- , 5- and 10- minutes Conventional, Specified, Expanded, and Combined Apgar scores were recorded. Then the neonates were followed and intracranial ultrasound imaging was performed, and the following information were recorded: the occurrence of birth asphyxia, hypoxic Ischemic Encephalopathy (HIE, intraventricular hemorrhage (IVH, and neonatal seizure.The Combined-Apgar score had the highest sensitivity (97% and specificity (99% in predicting birth asphyxia, followed by the Specified-Apgar score that was also highly sensitive (95% and specific (97%. The Expanded-Apgar score was highly specific (95% but not sensitive (67% and the Conventional-Apgar score had the lowest sensitivity (81% and low specificity (81% in predicting birth asphyxia. When adjusted for gestational age, only the low 5-minute Combined-Apgar score was independently associated with the occurrence of HIE (B = 1.61, P = 0.02 and IVH (B = 2.8, P = 0.01.The newly proposed Combined-Apgar score is highly sensitive and specific in predicting birth asphyxia and also is a good predictor of the occurrence of HIE and IVH in asphyxiated neonates.

  14. Correspondence between neurological symptoms and outcome of quantitative sensory testing in the hand-arm vibration syndrome.


    Ekenvall, L; Gemne, G; Tegner, R


    To evaluate neurological symptoms in the vibration syndrome, 55 patients with vascular and neurological symptoms in the hand who had been exposed to vibration were examined. Their exposure to vibration was estimated and neurological vascular symptoms were evaluated according to symptom scales. Temperature thresholds were measured on the right thenar eminence and on the distal volar aspect of the second and third fingers held together on both sides. Vibration thresholds were measured dorsally ...

    The main therapeutic strategy against human T lymphotropic virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) characterized by lower extremity motor dysfunction is immunomodulatory treatment, with drugs such as corticosteroid hormone and interferon-α, at present. However, there are many issues in long-term treatment with these drugs, such as insufficient effects and various side effects. We now urgently need to develop other therapeutic strategies. The heparinoid, pentosan polysulfate sodium (PPS), has been safely used in Europe for the past 50 years as a thrombosis prophylaxis and for the treatment of phlebitis. We conducted a clinical trial to test the effect of subcutaneous administration of PPS in 12 patients with HAM/TSP in an open-labeled design. There was a marked improvement in lower extremity motor function, based on reduced spasticity, such as a reduced time required for walking 10 m and descending a flight of stairs. There were no significant changes in HTLV-I proviral copy numbers in peripheral blood contrary to the inhibitory effect of PPS in vitro for intercellular spread of HTLV-I. However, serum soluble vascular cell adhesion molecule (sVCAM)-1 was significantly increased without significant changes of serum level of chemokines (CXCL10 and CCL2). There was a positive correlation between increased sVCAM-1and reduced time required for walking 10 m. PPS might induce neurological improvement by inhibition of chronic inflammation in the spinal cord, through blocking the adhesion cascade by increasing serum sVCAM-1, in addition to rheological improvement of the microcirculation. PPS has the potential to be a new therapeutic tool for HAM/TSP.

    Full Text Available Lysozyme amyloidosis is a hereditary disease in which mutations in the gene coding for lysozyme leads to misfolding and consequently accumulation of amyloid material. To improve understanding of the processes involved we expressed human wild type (WT lysozyme and the disease-associated variant F57I in the central nervous system (CNS of a Drosophila melanogaster model of lysozyme amyloidosis, with and without co-expression of serum amyloid p component (SAP. SAP is known to be a universal constituent of amyloid deposits and to associate with lysozyme fibrils. There are clear indications that SAP may play an important role in lysozyme amyloidosis, which requires further elucidation. We found that flies expressing the amyloidogenic variant F57I in the CNS have a shorter lifespan than flies expressing WT lysozyme. We also identified apoptotic cells in the brains of F57I flies demonstrating that the flies' neurological functions are impaired when F57I is expressed in the nerve cells. However, co-expression of SAP in the CNS prevented cell death and restored the F57I flies' lifespan. Thus, SAP has the apparent ability to protect nerve cells from damage caused by F57I. Furthermore, it was found that co-expression of SAP prevented accumulation of insoluble forms of lysozyme in both WT- and F57I-expressing flies. Our findings suggest that the F57I mutation affects the aggregation process of lysozyme resulting in the formation of cytotoxic species and that SAP is able to prevent cell death in the F57I flies by preventing accumulation of toxic F57I structures.

  18. Impact of presenting rhythm on short- and long-term neurological outcome in comatose survivors of cardiac arrest treated with therapeutic hypothermia (United States)

    Terman, Samuel W; Hume, Benjamin; Meurer, William J; Silbergleit, Robert


    Objective To compare short- and long-term neurological outcomes in comatose survivors of out-of-hospital cardiac arrest (OHCA) treated with mild therapeutic hypothermia (MTH) presenting with non-shockable (nSR) versus shockable (SR) initial rhythms. Design Retrospective cohort study. Setting ED and ICU of an academic hospital. Patients One hundred twenty-three consecutive post-OHCA adults (57 nSR, 67 SR) treated with therapeutic hypothermia between 2006 and 2012. Measurements and Main Results Data were collected from electronic health records. Neurological outcomes were dichotomized by Cerebral Performance Category at discharge and 6-12 month follow-up and analyzed via multivariable logistic regressions. Groups were similar, except nSR patients were more likely to have a history of diabetes mellitus (p = 0.01), be dialysis-dependent (p = 0.01), and not have bystander CPR (p = 0.05). At discharge, 3/57 (5%) patients with nSR versus 28/66 (42%) with SR had a favorable outcome (unadjusted OR 0.08, 95% CI 0.02-0.3; adjusted OR 0.1, 95% CI 0.03-0. 4). At follow-up, 4/55 (7%) versus 29/60 (48%) of patients with nSR and SR respectively had a favorable CPC (OR 0.08, 95% CI 0.03-0.3; adjusted OR 0.09, 95% CI 0.09-0.3). Among those surviving hospitalization, neurological outcome was more likely at long-term follow-up than at hospital discharge for both groups (OR 2.5, 95% CI 1.3-4.7; adjusted 2.9, 1.4-6.2). No significant interaction between changes in neurological status over time and presenting rhythm was seen (p=0.93). Conclusions These data indicate an association between initial nSR and significantly worse short- and long-term outcomes in patients treated with MTH. Among survivors, neurological status significantly improved over time for all patients and SR patients, and tended to improve over time for the small number of nSR patients who survived beyond hospitalization. No significant interaction between changes in neurological status over time and presenting rhythm

    The neurological outcome scale for traumatic brain injury (NOS-TBI) is a measure assessing neurological functioning in patients with TBI. We hypothesized that the NOS-TBI would exhibit adequate concurrent and predictive validity and demonstrate more sensitivity to change, compared with other well-established outcome measures. We analyzed data from the National Acute Brain Injury Study: Hypothermia-II clinical trial. Participants were 16-45 years of age with severe TBI assessed at 1, 3, 6, and 12 months postinjury. For analysis of criterion-related validity (concurrent and predictive), Spearman's rank-order correlations were calculated between the NOS-TBI and the glasgow outcome scale (GOS), GOS-extended (GOS-E), disability rating scale (DRS), and neurobehavioral rating scale-revised (NRS-R). Concurrent validity was demonstrated through significant correlations between the NOS-TBI and GOS, GOS-E, DRS, and NRS-R measured contemporaneously at 3, 6, and 12 months postinjury (all prate was outcome in the GOS, GOS-E, and DRS at 3 and 6 months postinjury (all poutcomes at 6 and 12 months postinjury (all poutcome measures. The NOS-TBI may enhance prediction of outcome in clinical practice and measurement of outcome in TBI research.

    WONG Kenneth KY; LIU Xue-lai


    Background Persistent gastro-esophageal reflux (GER) due to various pathological factors often results in overt clinical symptoms and signs,which is termed as gastro-esophageal reflux disease (GERD).Affected children usually present with failure to thrive,recurrent pneumonia or apnea.Many neurologically impaired children have symptoms related to GERD.Although laparoscopic fundoplication has been established to be an effective treatment modality for children with GERD,data on its role and long-term efficacy for neurologically impaired patients remain sparse.The aim of this study was to review the results of such patients who underwent laparoscopic fundoplication.Methods A retrospective review was performed from 1998 to 2009.All children with neurological impairment who had laparoscopic fundoplication were included.Results Fifty-nine GERD patients (male=32,female=27; mean age 6 years) were identified.All subjects showed symptoms of frequent emesis; 32 of them had history of hematemesis (54.2%); 54 had feeding difficulty; 35 (59.3%) had associated respiratory symptoms,including recurrent pneumonia.Gastrostomy was performed concurrently in 39 cases.There was no conversion to open procedure nor was there intra-operative complications and operative mortality.Emesis or hematemesis was controlled adequately in all.However,respiratory symptoms were not controlled in 10 patients (16.9%),and five of them required further respiratory assistance including nasal airway tube and tracheostomy.Clinical recurrence of GERD was not observed in any subject.Twelve patients died during follow-up (range from 3 months to 9 years) due to severe respiratory complications,cardiac arrest,and brain tumor.Conclusions Laparoscopic fundoplication is an excellent procedure for controlling clinically significant symptoms in neurological impaired patients with GERD.Further studies are required to assess the improvement of the quality of life in such patients.

  1. Compound heterozygosity of two functional null mutations in the ALPL gene associated with deleterious neurological outcome in an infant with hypophosphatasia. (United States)

    Hofmann, C; Liese, J; Schwarz, T; Kunzmann, S; Wirbelauer, J; Nowak, J; Hamann, J; Girschick, H; Graser, S; Dietz, K; Zeck, S; Jakob, F; Mentrup, B


    Hypophosphatasia (HPP) is a heterogeneous rare, inherited disorder of bone and mineral metabolism caused by different mutations in the ALPL gene encoding the isoenzyme, tissue-nonspecific alkaline phosphatase (TNAP). Prognosis is very poor in severe perinatal forms with most patients dying from pulmonary complications of their skeletal disease. TNAP deficiency, however, may also result in neurological symptoms such as neonatal seizures. The exact biological role of TNAP in the human brain is still not known and the pathophysiology of neurological symptoms due to TNAP deficiency in HPP is not understood in detail. In this report, we describe the clinical features and functional studies of a patient with severe perinatal HPP which presented with rapidly progressive encephalopathy caused by new compound heterozygous mutations in the ALPL gene which result in a functional ALPL "knock out", demonstrated in vitro. In contrast, an in vitro simulation of the genetic status of his currently asymptomatic parents who are both heterozygous for one mutation, showed a residual in vitro AP activity of above 50%. Interestingly, in our patient, the fatal outcome was due to progressive encephalopathy which was refractory to antiepileptic therapy including pyridoxine, rather than hypomineralization and respiratory insufficiency often seen in HPP patients. The patient's cranial MRI showed progressive cystic degradation of the cortex and peripheral white matter with nearly complete destruction of the cerebrum. To our knowledge, this is the first MRI-based report of a deleterious neurological clinical outcome due to a progressive encephalopathy in an infant harboring a functional human ALPL "knock out". This clinical course of disease suggests that TNAP is involved in development and may be responsible for multiple functions of the human brain. According to our data, a certain amount of residual TNAP activity might be mandatory for normal CNS function in newborns and early childhood.

    Full Text Available Background & Objectives: Classically associated with Plasmodium falciparum, neurological complications in severe malaria is associated with increased morbidity and mortality. However, reports implicate the long considered benign Plasmodium vivax for causing severe malaria as well. We aimed to analyze the cerebral complications in malaria, and study if there is a specie-related difference in the presentation and outcomes. Methods: We retrospectively compared patients of malaria hospitalised from 2009-15, with (n=105 and without (n=1155 neurological involvement in terms of outcomes, complications, demographic attributes, clinical features, and laboratory parameters. Subsequently, the same parameters were studied in those with cerebral malaria due to mono-infections of vivax or falciparum and their co-infection. Results: Cerebral malaria was observed in 8.3% (58/696, 7.4% (38/513 and 17.6% (6/51 of vivax, falciparum and combined plasmodial infections respectively. Those with cerebral malaria had significantly (p0.05. P. vivax emerged as the predominant cause of cerebral malaria and its virulence was comparable to P. falciparum.

  3. Influence of Fever and Hospital-Acquired Infection on the Incidence of Delayed Neurological Deficit and Poor Outcome after Aneurysmal Subarachnoid Hemorrhage

    G. Logan Douds


    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.

  4. Development of a patient reported outcome measure for fatigue in motor neurone disease: the Neurological Fatigue Index (NFI-MND

    Gibbons Chris J


    Full Text Available Abstract Background The objective of this research was to develop a disease-specific measure for fatigue in patients with motor neurone disease (MND by generating data that would fit the Rasch measurement model. Fatigue was defined as reversible motor weakness and whole-body tiredness that was predominantly brought on by muscular exertion and was partially relieved by rest. Methods Qualitative interviews were undertaken to confirm the suitability of a previously identified set of 52 neurological fatigue items as relevant to patients with MND. Patients were recruited from five U.K. MND clinics. Questionnaires were administered during clinic or by post. A sub-sample of patients completed the questionnaire again after 2-4 weeks to assess test-retest validity. Exploratory factor analyses and Rasch analysis were conducted on the item set. Results Qualitative interviews with ten MND patients confirmed the suitability of 52 previously identified neurological fatigue items as relevant to patients with MND. 298 patients consented to completing the initial questionnaire including this item set, with an additional 78 patients completing the questionnaire a second time after 4-6 weeks. Exploratory Factor Analysis identified five potential subscales that could be conceptualised as representing: 'Energy', 'Reversible muscular weakness' (shortened to 'Weakness', 'Concentration', 'Effects of heat' and 'Rest'. Of the original five factors, two factors 'Energy' and 'Weakness' met the expectations of the Rasch model. A higher order fatigue summary scale, consisting of items from the 'Energy' and 'Weakness' subscales, was found to fit the Rasch model and have acceptable unidimensionality. The two scales and the higher order summary scale were shown to fulfil model expectations, including assumptions of unidimensionality, local independency and an absence of differential item functioning. Conclusions The Neurological Fatigue Index for MND (NFI-MND is a simple, easy

  5. Amniotic Fluid Infection, Cytokine Levels, and Mortality and Adverse Pulmonary, Intestinal, and Neurologic Outcomes in Infants at 32 Weeks' Gestation or Less (United States)


    To what extent the risks of neonatal morbidities are directly related to premature birth or to biological mechanisms of preterm birth remains uncertain. We aimed to examine the effect of exposure to amniotic fluid (AF) infection and elevated cytokine levels on the mortality and pulmonary, intestinal, and neurologic outcomes of preterm infants, and whether these associations persist after adjustment for gestational age at birth. This retrospective cohort study included 152 premature singleton infants who were born at ≤ 32 weeks. AF obtained by amniocentesis was cultured; and interleukin-6 (IL-6) and IL-8 levels in AF were determined. The primary outcome was adverse perinatal outcome defined as the presence of one or more of the followings: stillbirth, neonatal death, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage, and periventricular leukomalacia. Logistic regression analysis was adjusted for gestational age at birth and other potential confounders. In bivariate analyses, elevated AF IL-6 and IL-8 levels were significantly associated with adverse perinatal outcome. These results were not changed after adjusting for potential confounders, such as low Apgar scores, mechanical ventilation, and surfactant application. However, the independent effect of elevated cytokine levels in AF disappeared when additionally adjusted for low gestational age at birth; consequently, low gestational age remained strongly associated with the risk of adverse perinatal outcome. In conclusion, elevated levels of pro-inflammatory cytokines in AF are associated with increased risk of adverse perinatal outcomes, but this risk is not independent of low gestational age at birth. Culture-proven AF infection is not associated with this risk. PMID:28145652

  6. Iatrogenic neurology. (United States)

    Sposato, Luciano A; Fustinoni, Osvaldo


    Iatrogenic disease is one of the most frequent causes of hospital admissions and constitutes a growing public health problem. The most common type of iatrogenic neurologic disease is pharmacologic, and the central and peripheral nervous systems are particularly vulnerable. Despite this, iatrogenic disease is generally overlooked as a differential diagnosis among neurologic patients. The clinical picture of pharmacologically mediated iatrogenic neurologic disease can range from mild to fatal. Common and uncommon forms of drug toxicity are comprehensively addressed in this chapter. While the majority of neurologic adverse effects are listed and referenced in the tables, the most relevant issues are further discussed in the text.

    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.

    Full Text Available Natalizumab (Tysabri® is a monoclonal antibody that prevents inflammatory cells from binding to brain endothelial cells and passing into the brain parenchyma. Natalizumab is a highly effective treatment for relapsing-remitting multiple sclerosis (MS. Progressive multifocal leukoencephalopathy (PML is an opportunistic brain JC virus infection that has been shown to be associated with natalizumab treatment. We describe PML in a patient with MS after 44 monthly infusions of natalizumab. With the aid of a routine MRI scan, PML was detected before any unambiguous clinical manifestations had emerged. PML was treated with plasma exchange to accelerate removal of natalizumab. Mirtazapine and mefloquine was promptly added and approximately one month after plasma exchange, when an immune-reconstitution-inflammatory-syndrome (IRIS appeared, steroid treatment was initiated. Steroid treatment was then continued until no virus could be detected in the cerebrospinal fluid. The outcome was favourable. We believe that this case clearly illustrates the importance of an early, presymptomatic, detection of PML and an adequate treatment. We also propose that surveillance with MRI scans, every 3 months after 24 months of treatment, should be performed in JC virus antibody positive natalizumab-treated MS patients in order to detect PML in an early phase.

    Acute hyperammonemia has a variety of etiologies and clinical manifestations. If not treated early in neonates, it leads to irreversible brain damage or death. We present a 7-day-old female patient who was brought to the emergency department with drownsiness and vomiting. Metabolic work-up revealed a blood ammonia level of 290 μmol/L (normal carbamylglutamate (NCG) was added resulting in a rapid normalisation of ammonemia. Feedings were progressively reintroduced, the ammonia levels remained low. The results of the metabolic work-up were compatible with carbamyl phosphate synthase 1 (CPS1) or N-acetyl glutamate synthase (NAGS) deficiency. Genetic analysis confirmed the latter diagnosis with a homozygous mutation c. 1450T > C (p.W484R) in exon 6 of the NAGS gene in the patient and a carrier state in both parents. At the age of 9 months, the child is growing well with normal neurological development, under treatment with NCG 100 mg/kg/day and a normal diet. Conclusion: This case highlights the importance of keeping a high index of suspicion and early testing for ammonia levels in neonates/children with unexplained encephalopathy. In neonates with congenital hyperammonemia, NCG should always be started together with the standard management of hyperammonemia until all laboratory investigations are complete or indicate another disease.

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

    LENUS (Irish Health Repository)

    Ryan, C Anthony


    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.

  13. Neurological outcome and risk of recurrence depending on the anterior vs. posterior arterial distribution in children with stroke. (United States)

    Touré, A; Chabrier, S; Plagne, M D; Presles, E; des Portes, V; Rousselle, C


    We report the outcome of 46 previously healthy children with arterial ischemic stroke. After a mean follow-up of 26 months, five (11%) children suffered a recurrence and 28 (61%) were left with sequelae. The prevalence and the severity of the sequelae were similar irrespective of whether the localization of the accident was anterior or posterior. However, a recurrence was significantly more frequent in the posterior than in the anterior group (4/14 vs. 1/32; p=0.025). These observations may lead to the establishment of therapeutic guidelines according to the localization of the infarct.

    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.

    The United States is with 37,451 home births in 2014 the country with the largest absolute number of home births among all developed countries. The purpose of this study was to examine the occurrence and risks of a 5-minute Apgar score of zero and neonatal seizures or serious neurologic dysfunction in women with a history of prior cesarean delivery for planned home vaginal birth after cesarean (VBAC), compared to hospital VBAC and hospital birth cesarean deliveries for term normal weight infants in the United States from 2007-2014. We report in this study outcomes of women who had one or more prior cesarean deliveries and included women who had a successful vaginal birth after a trial of labor after cesarean (TOLAC) at home and in the hospital, and a repeat cesarean delivery in the hospital. We excluded preterm births (Apgar score of 0 of 1 in 890 (11.24/10,000, relative risk 9.04, 95% confidence interval 4-20.39, p<.0001) and an incidence of neonatal seizures or severe neurologic dysfunction of 1 in 814 (Incidence: 12.27/10,000, relative risk 11.19, 95% confidence interval 5.13-24.29, p<.0001). Because of the significantly increased neonatal risks, obstetric providers should therefore not offer or perform planned home TOLACs and for those desiring a VBAC should strongly recommend a planned TOLAC in the appropriate hospital setting. We emphasize that this stance should be accompanied by effective efforts to make TOLAC available in the appropriate hospital setting.

    Background There is no standard palliative care outcome measure for people with progressive long term neurological conditions (LTNC). This study aims to determine the psychometric properties of a new 8-item palliative care outcome scale of symptom burden (IPOS Neuro-S8) in this population. Data and Methods Data were merged from a Phase II palliative care intervention study in multiple sclerosis (MS) and a longitudinal observational study in idiopathic Parkinson’s disease (IPD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). The IPOS Neuro-S8 was assessed for its data quality, score distribution, ceiling and floor effects, reliability, factor structure, convergent and discriminant validity, concurrent validity with generic (Palliative care Outcome Scale) and condition specific measures (Multiple Sclerosis Impact Scale; Non-motor Symptoms Questionnaire; Parkinson’s Disease Questionnaire), responsiveness and minimally clinically important difference. Results Of the 134 participants, MS patients had a mean Extended Disability Status Scale score 7.8 (SD = 1.0), patients with an IPD, MSA or PSP were in Hoehn & Yahr stage 3–5. The IPOS Neuro-S8 had high data quality (2% missing), mean score 8 (SD = 5; range 0–32), no ceiling effects, borderline floor effects, good internal consistency (Cronbach’s α = 0.7) and moderate test-retest reliability (intraclass coefficient = 0.6). The results supported a moderately correlated two-factor structure (Pearson’s r = 0.5). It was moderately correlated with generic and condition specific measures (Pearson’s r: 0.5–0.6). There was some evidence for discriminant validity in IPD, MSA and PSP (p = 0.020), and for good responsiveness and longitudinal construct validity. Conclusions IPOS Neuro-S8 shows acceptable to promising psychometric properties in common forms of progressive LTNCs. Future work needs to confirm these findings with larger samples and its usefulness in wider disease groups. PMID

    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

    Schor, Nina F


    As it is currently configured, completion of child neurology residency requires performance of 12 months of training in adult neurology. Exploration of whether or not this duration of training in adult neurology is appropriate for what child neurology is today must take into account the initial reasons for this requirement and the goals of adult neurology training during child neurology residency.

  20. Efficacy and safety comparison of DL-3-n-butylphthalide and Cerebrolysin: Effects on neurological and behavioral outcomes in acute ischemic stroke. (United States)

    Xue, Li-Xia; Zhang, Ting; Zhao, Yu-Wu; Geng, Zhi; Chen, Jing-Jiong; Chen, Hao


    Cerebrolysin and DL-3-n-butylphthalide (NBP) have each shown neuroprotective efficacy in preclinical models of acute ischemic stroke (AIS) and passed clinical trials as therapeutic drugs for AIS. The present study was a clinical trial to assess and compare the efficacy and safety of NBP and Cerebrolysin in the reduction of neurological and behavioral disability following AIS. A randomized, double-blind trial was conducted with enrolment of 60 patients within 12 h of AIS. In addition to routine treatment, patients were randomly assigned to receive a 10-day intravenous administration of NBP, Cerebrolysin or placebo. National Institutes of Health Stroke Scale (NIHSS) and Barthel Index (BI) scores were used to evaluate the efficacy of the treatment in the patients with AIS at 11 and 21 days after the initiation of therapy. Adverse events were also analyzed among the three groups. After 10 days of treatment with NBP or Cerebrolysin, the NIHSS and BI scores at day 21 showed statistical differences compared with those in the placebo group (PCerebrolysin groups were higher than those in the placebo group at days 11 and 21 (PCerebrolysin. The results indicate that NBP may be more effective than Cerebrolysin in improving short-term outcomes following AIS. This trial is registered at with clinical trial identifier number NCT02149875.

    Sritam Jena


    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.

    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.

  5. Brain-derived neurotrophic factor delivered to the brain using poly (lactide-co-glycolide) nanoparticles improves neurological and cognitive outcome in mice with traumatic brain injury. (United States)

    Khalin, Igor; Alyautdin, Renad; Wong, Tin Wui; Gnanou, Justin; Kocherga, Ganna; Kreuter, Jörg


    Currently, traumatic brain injury (TBI) is the leading cause of death or disabilities in young individuals worldwide. The multi-complexity of its pathogenesis as well as impermeability of the blood-brain barrier (BBB) makes the drug choice and delivery very challenging. The brain-derived neurotrophic factor (BDNF) regulates neuronal plasticity, neuronal cell growth, proliferation, cell survival and long-term memory. However, its short half-life and low BBB permeability are the main hurdles to be an effective therapeutic for TBI. Poly (lactic-co-glycolic acid) (PLGA) nanoparticles coated by surfactant can enable the delivery of a variety of molecules across the BBB by receptor-mediated transcytosis. This study examines the ability of PLGA nanoparticles coated with poloxamer 188 (PX) to deliver BDNF into the brain and neuroprotective effects of BNDF in mice with TBI. C57bl/6 mice were subjected to weight-drop closed head injuries under anesthesia. Using enzyme-linked immunosorbent assay, we demonstrated that the intravenous (IV) injection of nanoparticle-bound BDNF coated by PX (NP-BDNF-PX) significantly increased BDNF levels in the brain of sham-operated mice (p brain in TBI mice compared to controls. This study also showed using the passive avoidance (PA) test, that IV injection of NP-BDNF-PX 3 h post-injury prolonged the latent time in mice with TBI thereby reversing cognitive deficits caused by brain trauma. Finally, neurological severity score test demonstrated that our compound efficiently reduced the scores at day 7 after the injury indicating the improvement of neurological deficit in animals with TBI. This study shows that PLGA nanoparticles coated with PX effectively delivered BDNF into the brain, and improved neurological and cognitive deficits in TBI mice, thereby providing a neuroprotective effect.

    Full Text Available OBJECTIVE: Neurologic complications are known as important cause of morbidity and mortality in orthotopic heart transplantation. Our aim was to identify the frequency and outcome of neurologic complications after heart transplantation in a prospective observational study. METHOD: From September 93 to September 99, as part of our routine heart transplantation protocol all patients with end-stage cardiac failure were evaluated by the same neurologist before and at the time of any neurologic event (symptom or complaint after transplantation. RESULTS: Out of 120 candidates evaluated, 62 were successfully transplanted (53 male; median age 45.5 years, median follow-up 26.8 months. Fifteen patients (24% had ischemic, 22 (35% idiopathic, 24 (39% Chagas' disease and 1 (2% had congenital cardiomyopathy. Neurologic complications occurred in 19 patients (31%: tremor, severe headache, transient encephalopathy and seizures related to drug toxicity or metabolic changes in 13; peripheral neuropathy in 4; and spinal cord compression in two (metastatic prostate cancer and epidural abscess. No symptomatic postoperative stroke was observed. CONCLUSIONS: Although frequent, neurologic complications were seldom related to persistent neurologic disability or death. Most of the complications resulted from immunosuppression, however, CNS infection was rare. The absence of symptomatic stroke in our series may be related to the lower frequency of ischemic cardiomyopathy.

  7. Neurologic Complications in the Intensive Care Unit. (United States)

    Rubinos, Clio; Ruland, Sean


    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.

  8. Quality Metrics in Inpatient Neurology. (United States)

    Dhand, Amar


    Quality of care in the context of inpatient neurology is the standard of performance by neurologists and the hospital system as measured against ideal models of care. There are growing regulatory pressures to define health care value through concrete quantifiable metrics linked to reimbursement. Theoretical models of quality acknowledge its multimodal character with quantitative and qualitative dimensions. For example, the Donabedian model distils quality as a phenomenon of three interconnected domains, structure-process-outcome, with each domain mutually influential. The actual measurement of quality may be implicit, as in peer review in morbidity and mortality rounds, or explicit, in which criteria are prespecified and systemized before assessment. As a practical contribution, in this article a set of candidate quality indicators for inpatient neurology based on an updated review of treatment guidelines is proposed. These quality indicators may serve as an initial blueprint for explicit quality metrics long overdue for inpatient neurology.

    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.

  10. Happiness and neurological diseases. (United States)

    Barak, Yoram; Achiron, Anat


    Happiness is an emotional state reflecting positive feelings and satisfaction with life, which, as an outcome in disease states or as an end point in clinical trials, is a neglected concept in most therapeutic areas. In neurological disease, happiness is important as it can be diminished either as a direct result of damage to neuronal tissue or as a reaction to a poor prognosis. The monitoring and maintenance of happiness and wellbeing have historically been considered to be peripheral to medicine. However, as happiness interacts with the patient's physical health, it is an important parameter to assess alongside all aspects of any given disease. Happiness provides a reliable overview of the patient's general status over and above standard parameters for quality of life, and is more wide-ranging than the narrow measures of disease activity or treatment efficacy that are the focus of most clinical trials. In many studies, happiness has been associated with health and success in most areas of life, including performance at work, sporting achievement and social functioning. For approximately a decade, previously studied aspects of psychology have been grouped under the label of positive psychology (PoP). Principles of this discipline are now being used to guide some treatments in neurological and psychiatric diseases. PoP aims to define patient wellbeing in scientific terms and to increase understanding of happiness, meaning in life, resilience and character strengths, as well as to determine how this knowledge can be applied clinically to promote health. Some evidence has emerged recently suggesting that improvements in patient status can result from interventions to improve the patient's level of happiness in diseases, including epilepsy, Huntington's disease, multiple sclerosis, Parkinson's disease and stroke. Several effective approaches to increase happiness employ activities to engage and stimulate patients who might otherwise be unoccupied and isolated. In

  11. Neurology and neurologic practice in China. (United States)

    Shi, Fu-Dong; Jia, Jian-Ping


    In the wake of dramatic economic success during the past 2 decades, the specialized field of neurology has undergone a significant transformation in China. With an increase in life expectancy, the problems of aging and cognition have grown. Lifestyle alterations have been associated with an epidemiologic transition both in the incidence and etiology of stroke. These changes, together with an array of social issues and institution of health care reform, are creating challenges for practicing neurologists throughout China. Notable problems include overcrowded, decrepit facilities, overloaded physician schedules, deteriorating physician-patient relationships, and an insufficient infrastructure to accommodate patients who need specialized neurologic care. Conversely, with the creation of large and sophisticated neurology centers in many cities across the country, tremendous opportunities exist. Developments in neurologic subspecialties enable delivery of high-quality care. Clinical and translational research based on large patient populations as well as highly sophisticated technologies are emerging in many neurologic centers and pharmaceutical companies. Child neurology and neurorehabilitation will be fast-developing subdisciplines. Given China's extensive population, the growth and progress of its neurology complex, and its ever-improving quality control, it is reasonable to anticipate that Chinese neurologists will contribute notably to unraveling the pathogenic factors causing neurologic diseases and to providing new therapeutic solutions.

  12. Pharmacological complement inhibition at the C3 convertase level promotes neuronal survival, neuroprotective intracerebral gene expression, and neurological outcome after traumatic brain injury. (United States)

    Leinhase, Iris; Schmidt, Oliver I; Thurman, Joshua M; Hossini, Amir M; Rozanski, Michal; Taha, Mohy E; Scheffler, Alice; John, Thilo; Smith, Wade R; Holers, V Michael; Stahel, Philip F


    The complement system represents an important mediator of neuroinflammation in traumatic brain injury. We have previously shown that transgenic mice with central nervous system-targeted overexpression of Crry, a potent murine complement inhibitor at the level of C3 convertases, are protected from complement-mediated neuropathological sequelae in brain-injured mice. This knowledge was expanded in the present study to a pharmacological approach by the use of a recombinant Crry molecule (termed Crry-Ig) which was recently made available in a chimeric form fused to the non-complement fixing mouse IgG1 Fc region. In a standardized model of closed head injury in mice, the systemic injection of 1 mg Crry-Ig at 1 h and 24 h after trauma resulted in a significant neurological improvement for up to 7 days, as compared to vehicle-injected control mice (P complement inhibition represents a promising approach for attenuation of neuroinflammation and secondary neurodegeneration after head injury.

  13. The ketogenic diet as a treatment paradigm for diverse neurological disorders. (United States)

    Stafstrom, Carl E; Rho, Jong M


    Dietary and metabolic therapies have been attempted in a wide variety of neurological diseases, including epilepsy, headache, neurotrauma, Alzheimer disease, Parkinson disease, sleep disorders, brain cancer, autism, pain, and multiple sclerosis. The impetus for using various diets to treat - or at least ameliorate symptoms of - these disorders stems from both a lack of effectiveness of pharmacological therapies, and also the intrinsic appeal of implementing a more "natural" treatment. The enormous spectrum of pathophysiological mechanisms underlying the aforementioned diseases would suggest a degree of complexity that cannot be impacted universally by any single dietary treatment. Yet, it is conceivable that alterations in certain dietary constituents could affect the course and impact the outcome of these brain disorders. Further, it is possible that a final common neurometabolic pathway might be influenced by a variety of dietary interventions. The most notable example of a dietary treatment with proven efficacy against a neurological condition is the high-fat, low-carbohydrate ketogenic diet (KD) used in patients with medically intractable epilepsy. While the mechanisms through which the KD works remain unclear, there is now compelling evidence that its efficacy is likely related to the normalization of aberrant energy metabolism. The concept that many neurological conditions are linked pathophysiologically to energy dysregulation could well provide a common research and experimental therapeutics platform, from which the course of several neurological diseases could be favorably influenced by dietary means. Here we provide an overview of studies using the KD in a wide panoply of neurologic disorders in which neuroprotection is an essential component.

    Assessment of level of consciousness is very important in predicting patient's outcome from neurological illness. Glasgow coma scale (GCS) is the most commonly used scale, and Full Outline of UnResponsiveness (FOUR) score is also recently validated as an alternative to GCS in the evaluation of the level of consciousness. We carried out a prospective study in 97 patients aged above 16 years. We measured GCS and FOUR score within 24 h of Intensive Care Unit admission. The mean GCS and the FOUR scores were lower among nonsurvivors than among the survivors and were statistically significant (P < 0.001). Discrimination for GCS and FOUR score was fair with the area under the receiver operating characteristic curve of 0.79 and 0.82, respectively. The cutoff point with best Youden index for GCS and FOUR score was 6.5 each. Below the cutoff point, mortality was higher in both models (P < 0.001). The Hosmer-Lemeshow Chi-square coefficient test showed better calibration with FOUR score than GCS. A positive correlation was seen between the models with Spearman's correlation coefficient of 0.91 (P < 0.001). PMID:27630460

    Piber, D; Hinkelmann, K; Gold, S M; Heesen, C; Spitzer, C; Endres, M; Otte, C


    In many neurological diseases a depressive syndrome is a characteristic sign of the primary disease or is an important comorbidity. Post-stroke depression, for example, is a common and relevant complication following ischemic brain infarction. Approximately 4 out of every 10 stroke patients develop depressive disorders in the course of the disease which have a disadvantageous effect on the course and the prognosis. On the other hand depression is also a risk factor for certain neurological diseases as was recently demonstrated in a meta-analysis of prospective cohort studies which revealed a much higher stroke risk for depressive patients. Furthermore, depression plays an important role in other neurological diseases with respect to the course and quality of life, such as Parkinson's disease, multiple sclerosis and epilepsy. This article gives a review of the most important epidemiological, pathophysiological and therapeutic aspects of depressive disorders as a comorbidity of neurological diseases and as a risk factor for neurological diseases.

  17. [Palliative care in neurology]. (United States)

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


    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.

  18. Neurology and international organizations. (United States)

    Mateen, Farrah J


    A growing number of international stakeholders are engaged with neurologic diseases. This article provides a brief overview of important international stakeholders in the practice of neurology, including global disease-specific programs, United Nations agencies, governmental agencies with international influence, nongovernmental organizations, international professional organizations, large private donors, private-public partnerships, commercial interests, armed forces, and universities and colleges. The continued engagement of neurologists is essential for the growing number of international organizations that can and should incorporate neurologic disease into their global agendas.

  19. Neurologic management following cardiac arrest. (United States)

    Bircher, N G


    Optimal neurologic outcome after cardiac arrest requires careful attention to the details of both intracranial and extracranial homeostasis. A high index of suspicion regarding the potential causes and complications of cardiac arrest facilitates discovery and treatment of problems before they adversely affect neurologic outcome. The future is bright for resuscitation research: Our fundamental understanding of cerebral ischemia and its consequences has dramatically improved, and this knowledge can hopefully be transferred to clinical useful modes of therapy. However, the transition from a promising, therapeutically effective intervention in animals to the demonstration that treatment is effective following cardiac arrest in humans is an important and difficult step. The patient population is heterogeneous before the insult, the duration and severity of the insult are variable, and the effectiveness of cardiopulmonary resuscitation varies among institutions. Therefore, the only means of demonstrating clinical efficacy is the performance of a large clinical trial. The Resuscitation Research Center at the University of Pittsburgh has developed and coordinated a multicenter, multinational team of investigators who have completed one definitive trial of postarrest barbiturate therapy and are currently completing a similar trial using a calcium entry blocker. Despite the formidable obstacles posed by such comprehensive efforts, they provide the mechanism for determining whether the cost of a new treatment modality is justified by the likelihood of improved mortality or morbidity.

    Full Text Available Neurologic side effects related to cancer therapy are a common problem in oncology practice. These complications can negatively affect the management of the patient, because they can inhibit treatment and diminish quality of life. Therefore specific skills are required to recognise symptoms and clinical manifestations. This review focuses on the most common neurologic complications to improve physician’s familiarity in determining the aetiology of these symptoms.

  3. Neurology in Asia. (United States)

    Tan, Chong-Tin


    Asia is important as it accounts for more than half of the world population. The majority of Asian countries fall into the middle income category. As for cultural traditions, Asia is highly varied, with many languages spoken. The pattern of neurologic diseases in Asia is largely similar to the West, with some disease features being specific to Asia. Whereas Asia constitutes 60% of the world's population, it contains only 20% of the world's neurologists. This disparity is particularly evident in South and South East Asia. As for neurologic care, it is highly variable depending on whether it is an urban or rural setting, the level of economic development, and the system of health care financing. To help remedy the shortage of neurologists, most counties with larger populations have established training programs in neurology. These programs are diverse, with many areas of concern. There are regional organizations serving as a vehicle for networking in neurology and various subspecialties, as well as an official journal (Neurology Asia). The Asian Epilepsy Academy, with its emphasis on workshops in various locations, EEG certification examination, and fellowships, may provide a template of effective regional networking for improving neurology care in the region.

  4. Acetylcholinesterase inhibition ameliorates deficits in motivational drive

    Directory of Open Access Journals (Sweden)

    Martinowich Keri


    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.

  5. Genomics in Neurological Disorders

    Guangchun Han; Jiya Sun; Jiajia Wang; Zhouxian Bai; Fuhai Song; Hongxing Lei


    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.

  6. Emergency Neurologic Life Support: Meningitis and Encephalitis. (United States)

    Gaieski, David F; Nathan, Barnett R; O'Brien, Nicole F


    Bacterial meningitis and viral encephalitis, particularly herpes simplex encephalitis, are severe neurological infections that, if not treated promptly and effectively, lead to poor neurological outcome or death. Because treatment is more effective if given early, the topic of meningitis and encephalitis was chosen as an Emergency Neurological Life Support protocol. This protocol provides a practical approach to recognition and urgent treatment of bacterial meningitis and encephalitis. Appropriate imaging, spinal fluid analysis, and early empiric treatment is discussed. Though uncommon in its full form, the typical clinical triad of headache, fever, and neck stiffness should alert the clinical practitioner to the possibility of a central nervous system infection. Early attention to the airway and maintaining normotension is crucial in treatment of these patients, as is rapid treatment with anti-infectives and, in some cases, corticosteroids.

  11. Catatonia in Neurologic and Psychiatric Patients at a Tertiary Neurological Center. (United States)

    Espinola-Nadurille, Mariana; Ramirez-Bermudez, Jesus; Fricchione, Gregory L; Ojeda-Lopez, M Carmen; Perez-González, Andres F; Aguilar-Venegas, Luis C


    This study describes the prevalence, phenomenology, treatment, and outcome of neurological patients and psychiatric patients with catatonia at a tertiary neurological center. Clinical variables included nosological diagnoses and complications. Admission length and days with catatonia were used as outcome measures. Of 2,044 patients who were evaluated prospectively, 68 (3.32%) had catatonia, 42 (61.7%) were neurological patients, 19 (27.9%) were psychiatric patients, and 7 (10.2%) had drug-related diagnoses. Of all patients, the ratio of neurological to psychiatric patients was 3:1. Encephalitis was the most common diagnosis (N=26 [38.2%]), followed by schizophrenia (N=12 [17.6%]). Psychiatric patients exhibited a stuporous type of catatonia (15 [83.3%] versus 14 [33.3%], p>0.001), whereas neurological patients exhibited a mixed form of catatonia (25 [59.5%] versus 1 [5.6], pcatatonia. A total of 56 patients (82.3%) received lorazepam, and 14 patients (20.5%) underwent ECT. Second- and third-line treatments included amantadine, bromocriptine, and levodopa. Catatonia is a prevalent syndrome that can remit with proper and opportune treatment.

  12. Neurological legal disability

    Radhakrishna H


    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.

  13. Vaccination and neurological disorders

    Anastasia Gkampeta


    Full Text Available Active immunization of children has been proven very effective in elimination of life threatening complications of many infectious diseases in developed countries. However, as vaccination-preventable infectious diseases and their complications have become rare, the interest focuses on immunization-related adverse reactions. Unfortunately, fear of vaccination-related adverse effects can led to decreased vaccination coverage and subsequent epidemics of infectious diseases. This review includes reports about possible side effects following vaccinations in children with neurological disorders and also published recommendations about vaccinating children with neurological disorders. From all international published data anyone can conclude that vaccines are safer than ever before, but the challenge remains to convey this message to society.

  14. Neurology and detective writing. (United States)

    Kempster, Peter A; Lees, Andrew J


    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.

  15. Simulation in neurology. (United States)

    Micieli, Giuseppe; Cavallini, Anna; Santalucia, Paola; Gensini, Gianfranco


    Simulation is a frontier for disseminating knowledge in almost all the fields of medicine and it is attracting growing interest because it offers a means of developing new teaching and training models, as well as of verifying what has been learned in a critical setting that simulates clinical practice. The role of simulation in neurology, until now limited by the obvious physical limitations of the dummies used to train students and learners, is now increasing since, today, it allows anamnestic data to be related to the instrumental evidence necessary for diagnosis and therapeutic decision-making, i.e., to the findings of neurophysiological investigations (EEG, carotid and vertebral echography and transcranial Doppler, for example) and neuroradiological investigations (CT, MRI imaging), as well as vital parameter monitoring (ECG, saturimetry, blood pressure, respiratory frequency, etc.). Simulation, by providing learners with opportunities to discuss, with experts, different profiles of biological parameters (both during the simulation itself and in the subsequent debriefing session), is becoming an increasingly important tool for training those involved in evaluation of critical neurological patients (stroke, Guillan Barrè syndrome, myasthenia, status epilepticus, headache, vertigo, confusional status, etc.) and complex cases. In this SIMMED (Italian Society for Simulation in Medicine) position paper, the applications (present and, possibly, future) of simulation in neurology are reported.

  16. [Neurological Disorders and Pregnancy]. (United States)

    Berlit, P


    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.

    BACKGROUND: National Institutes of Health Stroke Scale is the most common scale used in stroke patients. An increase of four points or more within 24 h signifies early neurological deterioration. We aimed to establish how often early neurological deterioration occurs in a cohort selected...... by magnetic resonance imaging and which factors predicted early neurological deterioration. METHODS: In this single-center study, we collected epidemiological, imaging and outcome data on 569 consecutive patients undergoing reperfusion therapy after magnetic resonance imaging selection. RESULTS: Of these, 33...... (5.8%) experienced early neurological deterioration. Seven were due to a symptomatic intracerebral hemorrhage, 23 were caused by extension of ischemia on follow-up imaging and three were due to progression on the basis of small vessel disease. Early neurological deterioration was predicted...

  18. History of Neurology in China

    Wang Xinde


    @@In 1921, the first independent department of neurology was established in Beijing. Before 1949, all over China only 12 professional doctors lectured neurology in medical colleges. Only 30 medically trained personnel were engaged in the neurological departments. The neurological departments contained roughly 200 beds. The thesis on stroke was written by Zhang Shanlei and published in 1922. Author discussed the cerebral stroke on basis of Chinese traditional medicine and European medicine. The first Textbook of Neurology in China was written by Professor Cheng Yu-lin and was published in 1939. In 1952, the Chinese Society of Neurology and Psychiatry of Chinese Medical Association was established. In 1955, the first issue of the Chinese Journal of Neurology and Psychiatry was published.

  19. Neurological complications after liver retransplantation. (United States)

    Lopez, O L; Estol, C; Colina, I; Quiroga, J; Imvertarza, O C; van Thiel, D H


    Postoperative neurological complications in 185 patients who underwent two or more orthotopic liver transplantations were reviewed. The most common neurological complications were alteration of mental status (84%), seizures (33%) and focal motor deficits (15%). The frequency of neurological complications after a second orthotopic liver transplantation was significantly greater than that after a single orthotopic liver transplantation. However, neurological complications were more frequent after a second orthotopic liver transplantation than after a third transplant. Significantly more neurological complications occurred in patients who did not survive a year than in those who did, regardless of the number of transplants they underwent. These findings indicate that the risk of neurological complications among patients with multiple orthotopic liver transplantations is greater in those who require a second transplant; this risk appears to diminish after a third transplant. Importantly, the presence of neurological complications is associated with increased post-orthotopic liver transplantation mortality rate.

    Swick, Todd J


    Neurology, by virtue of its study of the brain, is the primary medical science for the elucidation of the anatomy, physiology, pathology and, ultimately, the function of sleep. There has been nothing short of a revolution in the science of sleep over the past 50 years. From the discovery of REM sleep to the identification of Hypocretin/Orexin the basic science and clinical field of sleep medicine has blossomed. This article will explore the anatomy, physiology, biochemistry and, to a limited extent, pathophysiology of the sleep/wake centers of the brain. The field of chronobiology will also be touched upon.

  2. Thermography in Neurologic Practice (United States)

    One kind of medical images that has been developed in the last decades is thermal images. These images are assessed by infrared cameras and have shown an exponential development in recent years. In this sense, the aim of this study was to describe possibilities of thermography usage in the neurologic practice. It was performed a systematic review in Web of Knowledge (Thompson Reuters), set in all databases which used two combination of keywords as “topic”: “thermography” and “neurology”; and “thermography” and “neurologic”. The chronological period was defined from 2000 to 2014 (the least 15 years). Among the studies included in this review, only seven were with experimental design. It is few to bring thermography as a daily tool in clinical practice. However, these studies have suggested good results. The studies of review and an analyzed patent showed that the authors consider the thermography as a diagnostic tool and they recommend its usage. It can be concluded that thermography is already used as a diagnostic and monitoring tool of patients with neuropathies, particularly in complex regional pain syndrome, and stroke. And yet, this tool has great potential for future research about its application in diagnosis of other diseases of neurological origin. PMID:26191090

  3. Neurology and diving. (United States)

    Massey, E Wayne; Moon, Richard E


    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.

  4. Neurological aspects of grief. (United States)

    Silva, Adriana C; de Oliveira Ribeiro, Natalia P; de Mello Schier, Alexandre R; Arias-Carrión, Oscar; Paes, Flavia; Nardi, Antonio E; Machado, Sergio; Pessoa, Tamires M


    Despite grief being a universal experience and the increased scientific attention paid to grief and bereavement in recent years, studies that seek to better understand the role of the neurological aspects of grief are still scarce. We found 5 studies that discussed the relationship between the neurological aspects of grief due to the death of a loved one. All studies showed an activation of common areas, i.e., the anterior cingulate cortex (ACC), posterior cingulate cortex (PCC), prefrontal cortex (PFC), insula and amygdala. These findings could indicate that there is a group of areas working together and responding to generate the symptomatology of grief. Because grief is a universal experience, it is essential that the necessary and effective support can be provided to those who experience the loss of someone considered important in their lives, and this requires understanding grief's manifestation, its differential diagnosis in reference to other clinical conditions, mainly psychiatric ones, and adequate forms of intervention and treatment when necessary. Proper understanding and support can help prevent the emergence of more serious health problems.

  5. Neurological deficit as a presentation of occult metastatic thyroid carcinoma. (United States)

    Izzard, Mark; McIvor, Nicholas; Chaplin, John; Ianovski, Ilia


    Three cases of occult metastatic thyroid carcinoma presenting with neurological deficits are reviewed. In each case the patient's initial presentation was with symptoms of neurological deficiency secondary to a spinal cord compression. All patients received a combination of surgery, external beam radiotherapy and postoperative thyroxine treatment. Two of the three patients are alive and well, able to mobilize with minor neurological dysfunction. The diagnosis and management of the patients, as well as their outcomes are reviewed, with a discussion on further management issues alongside a review of the current published work.

  6. Educational interventions in neurology: a comprehensive systematic review. (United States)

    McColgan, P; McKeown, P P; Selai, C; Doherty-Allan, R; McCarron, M O


    A fear of neurology and neural sciences (neurophobia) may have clinical consequences. There is therefore a need to formulate an evidence-based approach to neurology education. A comprehensive systematic review of educational interventions in neurology was performed. BEI, Cochrane Library, Dialog Datastar, EBSCO Biomedical, EBSCO Psychology & Behavioral Sciences, EMBASE, ERIC, First Search, MDConsult, Medline, Proquest Medical Library and Web of Knowledge databases were searched for all published studies assessing interventions in neurology education among undergraduate students, junior medical doctors and residents up to and including July 2012. Two independent literature searches were performed for relevant studies, which were then classified for level of evidence using the Centre of Evidence-based Medicine criteria and four levels of Kirkpatrick educational outcomes. One systematic review, 16 randomized controlled trials (RCTs), nine non-randomized cohort/follow-up studies, 33 case series or historically controlled studies and three mechanism-based reasoning studies were identified. Educational interventions showed favourable evaluation or assessment outcomes in 15 of 16 (94%) RCTs. Very few studies measured subsequent clinical behaviour (two studies) and patient outcomes (one study). There is very little high quality evidence of demonstrably effective neurology education. However, RCTs are emerging, albeit without meeting comprehensive educational criteria. An improving evidence base in the quality of neurology education will be important to reduce neurophobia.

  7. Emergency Neurological Life Support: Status Epilepticus. (United States)

    Claassen, Jan; Riviello, James J; Silbergleit, Robert


    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.

  8. Emotional disorders in neurological rehabilitation. (United States)

    House, Allan; Hosker, Christian


    Depression, anxiety, emotionalism, irritability, and apathy are common findings in the neurological rehabilitation setting and are associated with poorer outcomes. This chapter outlines the importance of detecting and attending to these disorders. The authors recommend the systematic use of self-report measures, tailored for those with cognitive or motor difficulties, in combination with interview-based assessments where suspicion of the presence of a disorder is aroused. A stepped care scheme for coordinating rehabilitation services is presented which highlights the importance of training all staff to be aware of the possibility of patients presenting with emotional disorders and the need to equip all staff with the skills to make emotional enquiries and to carry out brief interventions where indicated. Interventions should be based upon a combination of watchful waiting and optimization of clinical care followed by evidence-based brief therapies such as problem solving, motivational interviewing, and behavioral activation. Antidepressant prescribing should be reserved for the more severe cases and protocols should involve a system for reviewing and time-limiting prescriptions. This chapter aims to aid those designing services to produce simple and widely understood programs that meet the needs of this inherently heterogeneous client base.

  9. History of neurologic examination books. (United States)

    Boes, Christopher J


    The objective of this study was to create an annotated list of textbooks dedicated to teaching the neurologic examination. Monographs focused primarily on the complete neurologic examination published prior to 1960 were reviewed. This analysis was limited to books with the word "examination" in the title, with exceptions for the texts of Robert Wartenberg and Gordon Holmes. Ten manuals met the criteria. Works dedicated primarily to the neurologic examination without a major emphasis on disease description or treatment first appeared in the early 1900s. Georg Monrad-Krohn's "Blue Book of Neurology" ("Blue Bible") was the earliest success. These treatises served the important purpose of educating trainees on proper neurologic examination technique. They could make a reputation and be profitable for the author (Monrad-Krohn), highlight how neurology was practiced at individual institutions (McKendree, Denny-Brown, Holmes, DeJong, Mayo Clinic authors), and honor retiring mentors (Mayo Clinic authors).

  10. Consciousness: a neurological perspective. (United States)

    Cavanna, Andrea E; Shah, Sachin; Eddy, Clare M; Williams, Adrian; Rickards, Hugh


    Consciousness is a state so essentially entwined with human experience, yet so difficult to conceptually define and measure. In this article, we explore how a bidimensional model of consciousness involving both level of arousal and subjective awareness of the contents of consciousness can be used to differentiate a range of healthy and altered conscious states. These include the different sleep stages of healthy individuals and the altered states of consciousness associated with neurological conditions such as epilepsy, vegetative state and coma. In particular, we discuss how arousal and awareness are positively correlated in normal physiological states with the exception of REM sleep, while a disturbance in this relationship is characteristic of vegetative state, minimally conscious state, complex partial seizures and sleepwalking.

  13. [Music and neurology]. (United States)

    Arias Gómez, M


    Music perception and output are special functions of the human brain. Investigation in this field is growing with the support of modern neuroimaging techniques (functional magnetic resonance imaging, positron emission tomography). Interest in the music phenomenon and the disorders regarding its processing has been limited. Music is not just an artistic activity but a language to communicate, evoke and reinforce several emotions. Although the subject is still under debate, processing of music is independent of common language and each one uses independent circuits. One may be seriously affected and the other practically unharmed. On the other hand, there may be separate channels within the processing of music for the temporary elements (rhythm), melodic elements (pitch, timbre, and melody), memory and emotional response. The study of subjects with absolute pitch, congenital and acquired amusias, musicogenic epilepsy and musical hallucinations has greatly contributed to the knowledge of how the brain processes music. Music training involves some changes in morphology and physiology of professional musicians' brains. Stress, chronic pain and professional dystonias constitute a special field of musicians' disturbances that concerns neurological practice. Listening to and playing music may have some educational and therapeutic benefits.

  14. The neurology of ambiguity. (United States)

    Zeki, Semir


    One of the primordial functions of the brain is the acquisition of knowledge. The apparatus that it has evolved to do so is flexible enough to allow it to acquire knowledge about unambiguous conditions on the one hand (colour vision being a good example), and about situations that are capable of two or more interpretations, each one of which has equal validity with the others. However, in the latter instance, we can only be conscious of one interpretation at any given moment. The study of ambiguity thus gives us some insights into how activity at different stations of the brain can result in a micro-consciousness for an attribute, and also tell us something about interactions between different cerebral areas that result in several potential micro-conscious correlates, though only one predominates at any given time. Finally, the study of ambiguity also gives us insights into the neurological machinery that artists have tapped to create the ambiguity that is commonly a hallmark of great works of art.

    Full Text Available The mitochondrial cytopathies are genetically and phenotypically heterogeneous group of disorders caused by structural and functional abnormalities in mitochondria. 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. MRI brain showed multiple infarcts in MELAS, hyperintensities in putaminal areas in chorea and bilateral cerebellar atrophy in MERRF.

  16. [Neurological interpretation of dreams] . (United States)

    Pareja, J A; Gil-Nagel, A


    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.

  17. PPARγ-induced upregulation of CD36 enhances hematoma resolution and attenuates long-term neurological deficits after germinal matrix hemorrhage in neonatal rats. (United States)

    Flores, Jerry J; Klebe, Damon; Rolland, William B; Lekic, Tim; Krafft, Paul R; Zhang, John H


    Germinal matrix hemorrhage remains the leading cause of morbidity and mortality in preterm infants in the United States with little progress made in its clinical management. Survivors are often afflicted with long-term neurological sequelae, including cerebral palsy, mental retardation, hydrocephalus, and psychiatric disorders. Blood clots disrupting normal cerebrospinal fluid circulation and absorption after germinal matrix hemorrhage are thought to be important contributors towards post-hemorrhagic hydrocephalus development. We evaluated if upregulating CD36 scavenger receptor expression in microglia and macrophages through PPARγ stimulation, which was effective in experimental adult cerebral hemorrhage models and is being evaluated clinically, will enhance hematoma resolution and ameliorate long-term brain sequelae using a neonatal rat germinal matrix hemorrhage model. PPARγ stimulation (15d-PGJ2) increased short-term PPARγ and CD36 expression levels as well as enhanced hematoma resolution, which was reversed by a PPARγ antagonist (GW9662) and CD36 siRNA. PPARγ stimulation (15d-PGJ2) also reduced long-term white matter loss and post-hemorrhagic ventricular dilation as well as improved neurofunctional outcomes, which were reversed by a PPARγ antagonist (GW9662). PPARγ-induced upregulation of CD36 in macrophages and microglia is, therefore, critical for enhancing hematoma resolution and ameliorating long-term brain sequelae.

  18. Sparring And Neurological Function In Professional Boxers

    John W Stiller


    Full Text Available AbstractDespite increased interest regarding the potentially long-term negative impact of chronic traumatic brain injury (CTBI, limited research had been conducted regarding such injuries and neurological outcomes in real world settings. To increase understanding regarding the relationship between sparring (e.g., number of years actively training for professional boxing and neurological functioning, professional boxers (n = 237 who competed in Maryland between 2003 to 2008 completed measures regarding sparring exposure (Cumulative Sparring Index; CSI and performance on tests of cognition (Symbol Digit Modalities Test; SDMT and balance (Sharpened Romberg Test; SRT. Measures were completed prior to boxing matches. Higher scores on the CSI (increased sparring exposure were associated with poorer performance on both tests of cognition (SDMT and balance (SRT. A threshold effect was noted regarding performance on the SDMT, with those reporting CSI values greater than about 150 experiencing a decline in cognition. A history of frequent and/or intense sparring may pose a significant risk for developing boxing associated neurological sequelae. Implementing administration of clinically meaningful tests before bouts, such as the CSI, SDMT, and/or the SRT, as well as documentation of results into the boxer’s physicals or medical profiles may be an important step for improving boxing safety.

    youssef HNACH


    Full Text Available IntroductionThe purpose of this retrospective study was to report neurological manifestations noted in patients who were monitored for inflammatory bowel disease, in order to document the pathophysiological, clinical, progressive, and therapeutic characteristics of this entity.Material and methodsWe conducted a retrospective study on patients monitored -in the gastroenterology service in Ibn Sina Hospital in Rabat, Morocco- for inflammatory bowel disease from 1992 till 2013 and who developed neurological manifestations during its course. Patients with iatrogenic complications were excluded, as well as patients with cerebrovascular risk factors.ResultsThere were 6 patients, 4 of whom have developed peripheral manifestations. Electromyography enabled the diagnosis to be made and the outcome was favorable with disappearance of clinical manifestations and normalization of the electromyography.The other 2 patients, monitored for Crohn’s disease, developed ischemic stroke. Cerebral computed tomography angiography provided positive and topographic diagnosis. Two patients were admitted to specialized facilities.ConclusionNeurological manifestations in inflammatory bowel disease are rarely reported.  Peripheral neuropathies and stroke remain the most common manifestations. The mechanisms of these manifestations are not clearly defined yet. Currently, we hypothesize the interaction of immune mediators.

  20. Neurological examination in small animals

    Directory of Open Access Journals (Sweden)

    Viktor Paluš


    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.

  1. Cytokine Therapies in Neurological Disease. (United States)

    Azodi, Shila; Jacobson, Steven


    Cytokines are a heterogeneous group of glycoproteins that coordinate physiological functions. Cytokine deregulation is observed in many neurological diseases. This article reviews current research focused on human clinical trials of cytokine and anticytokine therapies in the treatment of several neurological disease including stroke, neuromuscular diseases, neuroinfectious diseases, demyelinating diseases, and neurobehavioral diseases. This research suggests that cytokine therapy applications may play an important role in offering new strategies for disease modulation and treatment. Further, this research provides insights into the causal link between cytokine deregulation and neurological diseases.

  2. Neurological findings of Lyme disease. (United States)

    Pachner, A. R.; Steere, A. C.


    Neurologic involvement of Lyme disease typically consists of meningitis, cranial neuropathy, and radiculoneuritis, alone or in combination, lasting for months. From 1976 to 1983, we studied 38 patients with Lyme meningitis. Headache and mild neck stiffness, which fluctuated in intensity, and lymphocytic pleocytosis were the common findings. Half of the patients also had facial palsies, which were unilateral in 12 and bilateral in seven. In addition, 12 patients had motor and/or sensory radiculoneuropathies; asymmetric weakness of extremities was the most common finding. Although incomplete presentations of neurologic involvement of Lyme disease may be confused with other entities, the typical constellation of neurologic symptoms represents a unique clinical picture.

  3. A century of Dutch neurology. (United States)

    Koehler, P J; Bruyn, G W; Moffie, D


    The Netherlands Society of Neurology evolved from the Society of Psychiatry founded in 1871. The name was changed into Netherlands Society of Psychiatry and Neurology (NSPN) in 1897. In the same year, the word neurology was also added to the name of the journal. The Society steadily blossomed, but in 1909 the first signs of dissatisfaction occurred: the Amsterdam Neurologists Society was founded. A few split-offs would follow. The number of members of the NSPN increased from 205 in 1920 to 585 in 1960. In the early 1960s, the Society was reorganised and would consist of two sections, one for psychiatry and one for neurology. However, this would not last, as a full separation was established in 1974. For several reasons, the name of the journal was changed four times until it assumed its present name in 1974. The 100th volume of CNN was not published, as expected. in 1996, but in 1998, because of two skipped publication years, one during WWII and another in the 1970s. During the last decades of the nineteenth century, teaching of neurology was mostly given within the frame of psychiatry, following the German tradition of 'brainpsychiatry' (organic or biologic psychiatry). The first official chair of psychiatry was founded at Utrecht, 1893 (Winkler). In Amsterdam, private teachers such as Delprat taught 'electro-therapy and nervous diseases' since the 1880s. The first extraordinary chair of neurology and electrotherapy was founded for his successor, Wertheim Salomonson in 1899. The first university clinic for psychiatry and neurology started at the Amsterdam Municipal University, when Winkler became professor of psychiatry and neurology in Amsterdam in 1896. Around the turn of the century, chairs of psychiatry and neurology were also founded in Groningen and Leiden. Separate chairs for neurology and psychiatry appeared in Amsterdam in 1923 and in Utrecht in 1936. Following an initiative of Brouwer, the first neurological university clinic opened its doors in

  4. Neurological Diseases, Disorders and Injuries in Canada: Highlights of a National Study. (United States)

    Bray, Garth M; Huggett, Deanna L


    The National Population Health Study of Neurological Conditions, a partnership between Neurological Health Charities Canada and the Government of Canada, was the largest study of neurological diseases, disorders, and injuries ever conducted in Canada. Undertaken between 2009 and 2013, the expansive program of research addressed the epidemiology, impacts, health services, and risk factors of 18 neurological conditions and estimated the health outcomes and costs of these conditions in Canada through 2031. This review summarizes highlights from the component projects of the study as presented in the synthesis report, Mapping Connections: An Understanding of Neurological Conditions in Canada. The key findings included new prevalence and incidence estimates, documentation of the diverse and often debilitating effects of neurological conditions, and identification of the utilization, economic costs, and current limitations of related health services. The study findings will support health charities, governments, and other stakeholders to reduce the impact of neurological conditions in Canada.

    Full Text Available Introduction: Paroxysmal sympathetic hyperactivity (PSH is a clinical disorder mainly caused by traumatic brain injury, stroke, encephalitis and other types of brain injury. The clinical features are episodes of hypertension, tachycardia, tachypnea, fever and dystonic postures. In this study, we described clinical profile and outcome of six patients of PSH admitted in neurocritical care unit. Materials and Methods: This was a prospective observational study conducted at neurology critical care unit of a tertiary care center. All patients admitted at neurology critical unit during 6-month period from August 2013 to January 2014 were screened for the occurrence of PSH. The clinical details and outcome was documented. Results: PSH was observed in 6 patients. Male to female ratio was 5:1. Mean age ± SD was 36.67 ± 15.19 years. The leading causes were traumatic brain injury (two patients, stroke (two patients and Japanese encephalitis (JE (one patient and tuberculous meningitis (one patient. Conclusion: PSH is an unusual complication in neurocritical care. It prolonged the hospitalization and hampers recovery. The other life-threatening conditions that mimic PSH should be excluded. The association with JE and tuberculous meningitis was not previously described in literature.

    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

  7. Hippocrates: the forefather of neurology. (United States)

    Breitenfeld, T; Jurasic, M J; Breitenfeld, D


    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.

    Gdynia, H J; Ampatzis, G; Diaconescu, A; Nowak, D A; Dabitz, R; Pfefferkorn, T


    Posterior reversible encephalopathy syndrome (PRES) is widely held to be a benign and potentially reversible disease. However, severe cases have been described in the literature. Data on the long-term outcome of these severe cases are scarce. Furthermore, there are no data focusing on potential benefits of neurological early rehabilitation in these patients. Here we present the clinical picture, neuroimaging features, rehabilitative course and long-term outcome of a patient with severe PRES who underwent early neurological rehabilitation.

  13. Paraneoplastic neurologic syndrome: A practical approach

    Directory of Open Access Journals (Sweden)

    Sudheeran Kannoth


    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.

  14. Neurological complications of underwater diving. (United States)

    Rosińska, Justyna; Łukasik, Maria; Kozubski, Wojciech


    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.

  15. [Neurologic complications of cocaine abuse]. (United States)

    Van Viet, H; Chevalier, P; Sereni, C; Bornet, P; Bautier, P; Degos, C F; Rullière, R


    Cocaine is increasingly used by drug addicts. It is considered harmless, but numerous, varied and often serious complications due to its abuse have been published. Among these, neurological complications are in the forefront. They include generalized or partial epileptic seizures, ischaemic or haemorrhagic cerebral vascular accidents, visual loss caused by optic neuropathy or by retinal artery occlusion, headaches and exacerbation of tics. Infections of the central nervous system are possible via endocarditis or septicaemia of venous or nasal origin. Neurological disorders may also occur as a consequence of a major cardiovascular complication induced by cocaine (myocardial infarction and/or dysrhythmia, aortic dissection). These neurological complications are unpredictable, and they weigh heavily on the functional and sometimes vital prognosis in habitual or occasional cocaine abusers.

  16. Neurology of endemic skeletal fluorosis

    Directory of Open Access Journals (Sweden)

    Reddy D


    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.

    Full Text Available Paraneoplastic neurologic disorders are extremely rare in cancer patients and are most commonly associated with certain tumors, such as ovarian cancer, small cell lung cancer, and breast cancer. We report here a paraneoplastic neurological syndrome in a 53-year-old man with colonic adenocarcinoma with a solitary liver metastasis. His paraneoplastic syndrome was successfully treated by methylprednisolone and primary oncologic therapies including neoadjuvant chemotherapy and definitive surgery. This is also the first documented case of simultaneous manifestation of a sensory neuropathy and limbic encephalitis with colon cancer.

  18. Dermatitis herpetiformis and neurological dysfunction. (United States)

    Wills, A J; Turner, B; Lock, R J; Johnston, S L; Unsworth, D J; Fry, L


    Dermatitis herpetiformis and coeliac disease are gluten sensitive diseases, which have common immunopathological and genetic mechanisms. Neuropsychiatric complications have been reported in up to 26% of patients with coeliac disease. This is probably an overestimate, because of the chance associations with some common neurological conditions such as epilepsy. The pathogenesis is speculative but it has been postulated that gluten is neurotoxic possibly via immune mechanisms. The frequency of neurological dysfunction in patients with dermatitis herpetiformis has not been characterised. Patients with dermatitis herpetiformis might be expected to be particularly susceptible to neuronal damage as some continue to consume gluten when their dermatological symptoms are controlled by dapsone. Thirty five patients were recruited with dermatitis herpetiformis from dermatology clinics at St Mary's Hospital, London and Queen's Medical Centre, Nottingham and investigated for evidence of neurological abnormality. All patients underwent a full neurological examination and were asked about their neurological and general medical history by means of a structured questionnaire. Serum samples were taken and screened for the presence of anti-neuronal antibodies (anti-Hu and Yo) as well as anti-gliadin (IgA and G) anti-endomysial (IgA), and anti-tissue transglutaminase (IgA) antibodies. Neurophysiological tests were carried out where appropriate. Only two patients were identified with unexplained neurological abnormalities (one essential tremor, and one chorea). Two other patients had a history of migraine. The patient with chorea also had borderline/equivocally positive anti-Hu antibodies by immunofluorescence assay. All other samples were negative for anti-neuronal antibodies. Fifteen patients were positive for anti-gliadin antibodies (IgA and/or IgG), four for anti-endomysial antibodies (monkey oesophagus or umbilical cord), and six for anti-tissue transglutaminase antibodies.

  19. Neurology in the electronic information age. (United States)

    Busis, N A


    This review discusses the state of neurology and the Internet at the turn of the millennium. First, some basic definitions about the Internet and its component protocols are presented. Next, ways neurologists and patients can use the Internet are enumerated. Internet resources or applications are available or are being created that can aid in the successful fulfillment of a neurologist's core professional activities: clinical care, teaching, research, and practice issues. Currently, the most useful categories of Internet resources for neurologists are electronic communication and access to knowledge bases. They fulfill needs that are not met by traditional, non-electronic media. There are many other types of Internet applications that supplement traditional medical methodologies. Finally, some problems and prospects concerning medical uses of the Internet are discussed: technological infrastructure including usability, security, meaning, validity/quality, value, outcomes, and responsibility. These issues must be successfully addressed if Internet computing is to become truly useful 'just in time' at the point of medical care. Solutions are actively under development today. The prospects are bright for neurology, and medicine in general, on the Internet. The Internet will become an essential medical device in the near future.

    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.

  1. Neurological Adverse Effects after Radiation Therapy for Stage II Seminoma

    Ebbeskov Lauritsen, Liv; Meidahl Petersen, Peter; Daugaard, Gedske


    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....../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....

  2. Allogeneic guinea pig mesenchymal stem cells ameliorate neurological changes in experimental colitis


    Stavely, Rhian; Robinson, Ainsley M.; Miller, Sarah; Boyd, Richard; Sakkal, Samy; Nurgali, Kulmira


    Background The use of mesenchymal stem cells (MSCs) to treat inflammatory bowel disease (IBD) is of great interest because of their immunomodulatory properties. Damage to the enteric nervous system (ENS) is implicated in IBD pathophysiology and disease progression. The most commonly used model to study inflammation-induced changes to the ENS is 2,4,6-trinitrobenzene-sulfonate acid (TNBS)-induced colitis in guinea pigs; however, no studies using guinea pig MSCs in colitis have been performed. ...

  5. [Sleep disorders in neurological diseases]. (United States)

    Kotterba, S


    Sleep disorders can be diagnosed in approximately 15 % of the population and have been shown to increase with age. The relationship between sleep disorders and neurological disorders, however, is still insufficiently considered in the clinical practice. Sleep disorders can be an early symptom of the disease, such as the presence of rapid eye movement (REM) sleep behavior disorder (RBD) as an early indicator of neurodegeneration. Sleep disorders have also been shown to be a main symptom of various neurological syndromes, such as in restless legs syndrome (RLS), periodic limb movement disorder (PLMD) and narcolepsy. The international classification of sleep disorders 2nd edition (ICSD 2) describes the main diagnoses, insomnia, circadian rhythm sleep disorders, sleep-related breathing disorders and hypersomnia but all of these can also appear as symptoms in various neurological diseases. Parasomnias are largely considered a differential diagnosis to nocturnal epilepsy. In this review, the main sleep disorders are described with a particular focus on how they relate to neurological diseases; in particular, how they influence disease-related symptoms and how they affect the course of the disease.

  8. Ion Channels in Neurological Disorders. (United States)

    Kumar, Pravir; Kumar, Dhiraj; Jha, Saurabh Kumar; Jha, Niraj Kumar; Ambasta, Rashmi K


    The convergent endeavors of the neuroscientist to establish a link between clinical neurology, genetics, loss of function of an important protein, and channelopathies behind neurological disorders are quite intriguing. Growing evidence reveals the impact of ion channels dysfunctioning in neurodegenerative disorders (NDDs). Many neurological/neuromuscular disorders, viz, Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, amyotrophic lateral sclerosis, and age-related disorders are caused due to altered function or mutation in ion channels. To maintain cell homeostasis, ion channels are playing a crucial role which is a large transmembrane protein. Further, these channels are important as it determines the membrane potential and playing critically in the secretion of neurotransmitter. Behind NDDs, losses of pathological proteins and defective ion channels have been reported and are found to aggravate the disease symptoms. Moreover, ion channel dysfunctions are eliciting a range of symptoms, including memory loss, movement disabilities, neuromuscular sprains, and strokes. Since the possible mechanistic role played by aberrant ion channels, their receptor and associated factors in neurodegeneration remained elusive; therefore, it is a challenging task for the neuroscientist to implement the therapeutics for targeting NDDs. This chapter reviews the potential role of the ion channels in membrane physiology and brain homeostasis, where ion channels and their associated factors have been characterized with their functional consequences in neurological diseases. Moreover, mechanistic role of perturbed ion channels has been identified in various NDDs, and finally, ion channel modulators have been investigated for their therapeutic intervention in treating common NDDs.

  12. [Neurology of hysteria (conversion disorder)]. (United States)

    Sonoo, Masahiro


    Hysteria has served as an important driving force in the development of both neurology and psychiatry. Jean Martin Charcot's devotion to mesmerism for treating hysterical patients evoked the invention of psychoanalysis by Sigmund Freud. Meanwhile, Joseph Babinski took over the challenge to discriminate between organic and hysterical patients from Charcot and found Babinski's sign, the greatest milestone in modern neurological symptomatology. Nowadays, the usage of the term hysteria is avoided. However, new terms and new classifications are complicated and inconsistent between the two representative taxonomies, the DSM-IV and ICD-10. In the ICD-10, even the alternative term conversion disorder, which was becoming familiar to neurologists, has also disappeared as a group name. The diagnosis of hysteria remains important in clinical neurology. Extensive exclusive diagnoses and over investigation, including various imaging studies, should be avoided because they may prolong the disease course and fix their symptoms. Psychological reasons that seem to explain the conversion are not considered reliable. Positive neurological signs suggesting nonorganic etiologies are the most reliable measures for diagnosing hysteria, as Babinski first argued. Hysterical paresis has several characteristics, such as giving-way weakness or peculiar distributions of weakness. Signs to uncover nonorganic paresis utilizing synergy include Hoover's test and the Sonoo abductor test.

    In 2015, cerebral stimulation becomes increasingly established in the treatment of pharmacoresistant epilepsy. Efficacy of endovascular treatment has been demonstrated for acute ischemic stroke. Deep brain stimulation at low frequency improves dysphagia and freezing of gait in Parkinson patients. Bimagrumab seems to increase muscular volume and force in patients with inclusion body myositis. In cluster-type headache, a transcutaneous vagal nerve stimulator is efficient in stopping acute attacks and also reducing their frequency. Initial steps have been undertaken towards modulating memory by stimulation of the proximal fornix. Teriflunomide is the first oral immunomodulatory drug for which efficacy has been shown in preventing conversion from clinical isolated syndrome to multiple sclerosis.

  14. Neurological manifestations in Fabry disease

    Institute of Scientific and Technical Information of China (English)

    Joseph Bruno Bidin Brooks; Yara Dadalti Fragoso


    Fabry disease (FD) is a rare, progressive, multisystem and highly debilitating disease. FD is an X-linked lysosome storage disorder that results in α-galactosidase A deifciency. The subsequent accumulation of glycosphingolipids is more evident in vascular endothelium and smooth-muscle cells. The resulting effect of the deposition is generalized inlfammation and vasculopathy, which can also affect the central and peripheral nervous system. FD progresses with kidney dysfunction, angiokeratoma of the skin, cardiomyopathy, cerebrovascular events and neurological disorders. In the present review, the neurological manifestations of FD are summarized with emphasis on cerebral vasculopathy, cochlear nerve dysfunction, psychiatric and cognitive symptoms, autonomic dysfunction and peripheral neuropathy. Enzyme replacement therapy is also discussed in the light of its more prominent effects when administered early in life, which make it essential to diagnose FD as soon as possible.

    Casella, Giovanni; Bordo, Bianca M; Schalling, Renzo; Villanacci, Vincenzo; Salemme, Marianna; Di Bella, Camillo; Baldini, Vittorio; Bassotti, Gabrio


    Celiac disease (CD) determines neurologic manifestations in 10% of all CD patients. We describe the most common clinical manifestations as cerebellar ataxia, gluten encephalopathy, multiple sclerosis, peripheral neuropathies, sensorineural hearing loss, epilepsy, headache, depression, cognitive deficiencies and other less described clinical conditions. Our aim is to perform, as more as possible, a review about the most recent update on the topics in international literature. It is important to consider clinical neurological manifestations in celiac patients and to research these conditions also in the follow-up because they may start also one year after the start of gluten free diet (GFD) as peripheral neuropathy. The association with autism is analysed and possible new association with non-celiac gluten sensitivity (NCGS) are considered.

    The clinical and neuropathologic findings of 55 adults and 30 children who received liver transplants were reviewed. Encephalopathy was the most common clinical neurologic syndrome and was usually caused by metabolic or anoxic causes. (Alzheimer type astrocytes were present in 73 per cent of patients, and evidence of diffuse hypoxic damage was present in 40 per cent of children and 25 per cent of adults.) Cerebrovascular lesions were a common finding with infarcts or hemorrhages present in 30 per cent of patients. CNS infections were documented in 34 per cent of patients. Seizures were present in a third of patients. Central pontine myelinolysis was present in 12 per cent of patients and was more common in adults than in children. Antemortem diagnosis of neurologic complications was more often based on clinical presentation rather than specific radiologic or laboratory tests.

    Semra Paydas


    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. 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

    BACKGROUND:The main aim of rehabilitation is to ameliorate motor function and use the damaged limbs in the activities of daily living.Several factors are needed in the self-recovery of the patients,and the most important one is to reduce spasm.Some mechanical repetitive movements can affect and change the excitability of motor neurons.OBJECTIVE:To observe the effect of repetitive training on ameliorating spasm of upper limbs of hemiplegic patients.DESIGN:A self-controlled observation before and after training.SETTING:Department of Rehabilitation,Xuanwu Hospital of Capital Medical University.PARTICI PANTS: Seven hemiplegic patients induced by brain injury were selected from the Department of Rehabilitation,Xuanwu Hospital,Capital Medical University from March to June in 2005.Inclusive criteria:①Agreed and able to participate in the 30-minute training of hand function; ②Without disturbance of understanding.The patients with aphasia or apraxia,manifestation of shoulder pain,and severe neurological or mental defects.For the 7 patients,the Rivermead motor assessment(RMA)scores ranged 0-10 points,the Rivermead mobility index(RMI)ranged 1-3,and modified Ashworth scale(MAS)was grade 2-4.Their horizontal extension of shoulder joint was 0°-30°,anteflextion was 0°-50°,internal rotation was 50°-90°,external rotation was 0°-10°:and the elbow joint could extend for 15°-135°.METHODS:The viva 2 serial MOTOmed exerciser(Reck Company,Germany)was used.There were three phases of A-B-A.①The phase A lasted for 1 week.The patient sat on a chair facting to the MOTOmed screen.and did the circumduction of upper limbs forwardly,30 minutes a day and 5 days a week.②The phase B lasted for 3 weeks.The training consisted of forward circumduction of upper limbs for 15 minutes.followed by backward ones for 15 minutes and 5-minute rest.③The training in the phase A was performed again for 2 weeks.The extensions of upper limbs were recorded at phase A,the extension and flexion of




  3. Cervical spinal canal narrowing and cervical neurologi-cal injuries

    Directory of Open Access Journals (Sweden)

    ZHANG Ling


    Full Text Available 【Abstract】Cervical spinal canal narrowing can lead to injury of the spinal cord and neurological symptoms in-cluding neck pain, headache, weakness and parasthesisas. According to previous and recent clinical researches, we investigated the geometric parameters of normal cervical spinal canal including the sagittal and transverse diameters as well as Torg ratio. The mean sagittal diameter of cervical spinal canal at C 1 to C 7 ranges from 15.33 mm to 20.46 mm, the mean transverse diameter at the same levels ranges from 24.45 mm to 27.00 mm and the mean value of Torg ratio is 0.96. With respect to narrow cervical spinal canal, the following charaterstics are found: firstly, extension of the cervical spine results in statistically significant stenosis as compared with the flexed or neutral positions; secondly, females sustain cervical spinal canal narrowing more easily than males; finally, the consistent narrowest cervical canal level is at C 4 for all ethnicity, but there is a slight variation in the sagittal diameter of cervical spinal stenosis (≤14 mm in Whites, ≤ 12 mm in Japanese, ≤13.7 mm in Chinese. Narrow sagittal cervical canal diameter brings about an increased risk of neurological injuries in traumatic, degenerative and inflam-matory conditions and is related with extension of cervical spine, gender, as well as ethnicity. It is hoped that this re-view will be helpful in diagnosing spinal cord and neuro-logical injuries with the geometric parameters of cervical spine in the future.

Materials and Methods: Sixty-two consecutive patients (26 women and 36 men; mean age 61 years, range 2-76 years with isolated head trauma seen within the first three hours of the trauma were included in the study. The Glasgow Coma score (GCS, platelet counts (Plt, prothrombin time (PT, partial thromboplastin time (PTT, fibrinogen, fibrin degradation products (FDP and D-dimer levels were measured. Head computerized tomography (CT findings were categorized as brain edema, linear fracture, depressed fracture, contusion and bleeding. Plt counts, PT, PTT, fibrinogen, FDP, D-dimer levels and CT findings were compared with both GCS and mortality in the first week. Statistical significance was accepted at P£0.05. Results: A marked negative relationship was found between GCS and PT, PTT, FDP and D-dimer levels ( P < 0.001. Plt levels did not correlate with GCS. Mortality was most strongly related to GCS, PT, FDP and D-dimer levels ( P < 0.001, P < 0.001, P < 0.001 and P < 0.001, respectively. We found no relationship between mortality and CT findings, nor was there any significant relationship between Plt, PTT and fibrinogen levels. Conclusion: GCS and fibrinolytic markers measured within the first three hours were useful in determining the prognosis of patients with isolated head trauma.

  6. Fucoidan Extracts Ameliorate Acute Colitis. (United States)

    Lean, Qi Ying; Eri, Rajaraman D; Fitton, J Helen; Patel, Rahul P; Gueven, Nuri


    Inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, are an important cause of morbidity and impact significantly on quality of life. Overall, current treatments do not sustain a long-term clinical remission and are associated with adverse effects, which highlight the need for new treatment options. Fucoidans are complex sulphated, fucose-rich polysaccharides, found in edible brown algae and are described as having multiple bioactivities including potent anti-inflammatory effects. Therefore, the therapeutic potential of two different fucoidan preparations, fucoidan-polyphenol complex (Maritech Synergy) and depyrogenated fucoidan (DPF) was evaluated in the dextran sulphate sodium (DSS) mouse model of acute colitis. Mice were treated once daily over 7 days with fucoidans via oral (Synergy or DPF) or intraperitoneal administration (DPF). Signs and severity of colitis were monitored daily before colons and spleens were collected for macroscopic evaluation, cytokine measurements and histology. Orally administered Synergy and DPF, but not intraperitoneal DPF treatment, significantly ameliorated symptoms of colitis based on retention of body weight, as well as reduced diarrhoea and faecal blood loss, compared to the untreated colitis group. Colon and spleen weight in mice treated with oral fucoidan was also significantly lower, indicating reduced inflammation and oedema. Histological examination of untreated colitis mice confirmed a massive loss of crypt architecture and goblet cells, infiltration of immune cells and oedema, while all aspects of this pathology were alleviated by oral fucoidan. Importantly, in this model, the macroscopic changes induced by oral fucoidan correlated significantly with substantially decreased production of at least 15 pro-inflammatory cytokines by the colon tissue. Overall, oral fucoidan preparations significantly reduce the inflammatory pathology associated with DSS-induced colitis and could therefore represent

    Møller, Anette Torvin; Jensen, Troels Staehelin


    Fabry's disease is an X-linked lysosomal storage disorder caused by a defect in the gene that encodes the lysosomal enzyme alpha-galactosidase A. Symptoms arise because of accumulation of globotriaosylceramide in multiple organs, resulting in severely reduced quality of life and premature death....... Neurological symptoms, such as burning sensations (occasionally accompanied by acroparesthesia) and stroke, are among the first to appear, and occur in both male and female patients.

    Cigarette smoke is a major health risk factor which significantly increases the incidence of diseases including lung cancer and respiratory infections. However, there is increasing evidence that smokers have a lower incidence of some inflamma- tory and neurodegenerative diseases. Nicotine is the main immunosuppressive constituent of cigarette smoke, which inhib-its both the innate and adaptive immune responses. Unlike cigarette smoke, nicotine is not yet considered to be a carcino-gen and may, in fact, have therapeutic potential as a neuroprotective and anti-inflammatory agent. This review provides a synopsis summarizing the effects of nicotine on the immune system and its (nicotine) influences on various neurological diseases.

  12. Neurology and psychiatry in Babylon. (United States)

    Reynolds, Edward H; Wilson, James V Kinnier


    We here review Babylonian descriptions of neurological and psychiatric disorders, including epilepsy, stroke, psychoses, obsessive compulsive disorder, phobias, psychopathic behaviour, depression and anxiety. Most of these accounts date from the first Babylonian dynasty of the first half of the second millennium BC, within a millennium and a half of the origin of writing. The Babylonians were remarkably acute and objective observers of medical disorders and human behaviour. Their detailed descriptions are surprisingly similar to modern 19th and 20th century AD textbook accounts, with the exception of subjective thoughts and feelings which are more modern fields of enquiry. They had no knowledge of brain or psychological function. Some neuropsychiatric disorders, e.g. stroke or facial palsy, had a physical basis requiring the attention of a physician or asû, using a plant and mineral based pharmacology; some disorders such as epilepsy, psychoses, depression and anxiety were regarded as supernatural due to evil demons or spirits, or the anger of personal gods, and thus required the intervention of the priest or ašipu; other disorders such as obsessive compulsive disorder and psychopathic behaviour were regarded as a mystery. The Babylonians were the first to describe the clinical foundations of neurology and psychiatry. We discuss these accounts in relation to subsequent and more modern clinical descriptions.

  13. White matter and behavioral neurology. (United States)

    Filley, Christopher M


    Although the study of higher brain function has traditionally focused on the cortical gray matter, recent years have witnessed the recognition that white matter also makes an important contribution to cognition and emotion. White matter comprises nearly half the brain volume and plays a key role in development, aging, and many neurologic and psychiatric disorders across the life span. More than 100 disorders exist in which white matter neuropathology is the primary or a prominent feature. A variety of neurobehavioral syndromes may result from these disorders; the concept of white matter dementia has been introduced as characteristic of many patients with white matter involvement, and a wide range of focal neurobehavioral syndromes and psychiatric disorders can also be related to dysfunction of myelinated tracts. Understanding the neurobehavioral aspects of white matter disorders is important for clinical diagnosis, treatment, prognosis, and research on brain-behavior relationships. Central to these investigations is the use of modern neuroimaging techniques, which have already provided substantial information on the characterization of white matter and its disorders, and which promise to advance our knowledge further with continued innovation. Diffusion tensor imaging is an exciting method that will assist with the identification of critical white matter tracts in the brain, and the localization of specific lesions that can be correlated with neurobehavioral syndromes. A behavioral neurology of white matter is thus emerging in which clinical observation combined with sophisticated neuroimaging will enable elucidation of the role of white matter connectivity in the distributed neural networks subserving higher brain function.

  14. Neurological disorders in hypertensive patients

    Directory of Open Access Journals (Sweden)

    N. V. Vakhnina


    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.

    Zara, Gabriella; Codemo, Valentina; Palmieri, Arianna; Schiff, Sami; Cagnin, Annachiara; Citton, Valentina; Manara, Renzo


    Hyperemesis gravidarum can impair correct absorption of an adequate amount of thiamine and can cause electrolyte imbalance. This study investigated the neurological complications in a pregnant woman with hyperemesis gravidarum. A 29-year-old pregnant woman was admitted for hyperemesis gravidarum. Besides undernutrition, a neurological examination disclosed weakness with hyporeflexia, ophthalmoparesis, multidirectional nystagmus and optic disks swelling; the patient became rapidly comatose. Brain MRI showed symmetric signal hyperintensity and swelling of periaqueductal area, hypothalamus and mammillary bodies, medial and posterior portions of the thalamus and columns of fornix, consistent with Wernicke encephalopathy (WE). Neurophysiological studies revealed an axonal sensory-motor polyneuropathy, likely due to thiamine deficiency or critical illness polyneuropathy. Sodium and potassium supplementation and parenteral thiamine were administered with improvement of consciousness state in a few days. WE evolved in Korsakoff syndrome. A repeat MRI showed a marked improvement of WE-related alterations and a new hyperintense lesion in the pons, suggestive of central pontine myelinolysis. No sign or symptom due to involvement of the pons was present.

  16. Neurological syndromes following organophosphate poisoning.

    Singh S


    Full Text Available Organophosphorous compounds, the anticholinesterases, produce significant morbidity and mortality in India. Although exact estimates are not available, hospital based statistics suggest that nearly half of the admissions to emergency with acute poisoning are due to organophosphates. Following accidental or suicidal exposure, these anticholinesterases lead to three well defined neurological syndromes i.e. initial life threatening acute cholinergic crisis which often requires management in intensive care unit, intermediate syndrome in which cranial nerve palsies, proximal muscle weakness and respiratory muscle weakness are common and patients often require respiratory support and delayed organophosphate induced polyneuropathy. In addition to these three classical neurological syndromes following acute exposure and in some following low dose chronic exposure, several neurobehavioural changes have been observed and these have been termed together as ′chronic organophosphate induced neuropsychiatric disorders′ (COPIND. Organo-phosphate compounds produce significant pesticide related illness in developing countries. There is, thus, a need to determine exact extent of the problem and to develop appropriate strategies to manage these cases with available resources in these countries.

  17. Losartan ameliorates dystrophic epidermolysis bullosa and uncovers new disease mechanisms. (United States)

    Nyström, Alexander; Thriene, Kerstin; Mittapalli, Venugopal; Kern, Johannes S; Kiritsi, Dimitra; Dengjel, Jörn; Bruckner-Tuderman, Leena


    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.

    Full Text Available Background: Neurological complications are common after orthotopic liver transplantation (OLT. We aimed to characterize the risk factors associated with neurological complications and mortality among patients who underwent OLT in the post-model for end-stage liver disease (MELD era.Methods: In a retrospective review, we evaluated 227 consecutive patients at the Keck Hospital of the University of Southern California before and after OLT to define the type and frequency of and risk factors for neurological complications and mortality.Results: Neurological complications were common (n=98, with encephalopathy being most frequent (56.8%, followed by tremor (26.5%, hallucinations (11.2%, and seizure (8.2%. Factors associated with neurological complications after OLT included preoperative dialysis, hepatorenal syndrome, renal insufficiency, intra-operative dialysis, preoperative encephalopathy, preoperative mechanical ventilation, and infection. Preoperative infection was an independent predictor of neurological complications (OR 2.83, 1.47 – 5.44. One-month mortality was 8.8% and was independently associated with urgent re-transplant, preoperative intubation, intraoperative arrhythmia, and intraoperative use of multiple pressors.Conclusion: Neurological complications are common in patients undergoing OLT in the post-MELD era, with encephalopathy being most frequent. An improved understanding of the risk factors related to both neurological complications and one-month mortality post-transplantation can better guide perioperative care and help improve outcomes among OLT patients.

  19. Omega-3 polyunsaturated fatty acids ameliorate neuroinflammation and mitigate ischemic stroke damage through interactions with astrocytes and microglia. (United States)

    Zendedel, Adib; Habib, Pardes; Dang, Jon; Lammerding, Leoni; Hoffmann, Stefanie; Beyer, Cordian; Slowik, Alexander


    Omega-3 polyunsaturated fatty acids (PUFA n3) provide neuroprotection due to their anti-inflammatory and anti-apoptotic properties as well as their regulatory function on growth factors and neuronal plasticity. These qualities enable PUFA n3 to ameliorate stroke outcome and limit neuronal damage. Young adult male rats received transient middle cerebral artery occlusion (tMCAO). PUFA n3 were intravenously administered into the jugular vein immediately after stroke and 12h later. We analyzed stroke volume and behavioral performance as well as the regulation of functionally-relevant genes in the penumbra. The extent of ischemic damage was reduced and behavioral performance improved subject to applied PUFA n3. Expression of Tau and growth-associated protein-43 genes were likewise restored. Ischemia-induced increase of cytokine mRNA levels was abated by PUFA n3. Using an in vitro approach, we demonstrate that cultured astroglial and microglia directly respond to PUFA n3 administration by preventing ischemia-induced increase of cyclooxygenase 2, hypoxia-inducible factor 1alpha, inducible nitric oxide synthase, and interleukin 1beta. Cultured cortical neurons also appeared as direct targets, since PUFA n3 shifted the Bcl-2-like protein 4 (Bax)/B-cell lymphoma 2 (Bcl 2) ratio towards an anti-apoptotic constellation. Thus, PUFA n3 reveal a high neuroprotective and anti-inflammatory potential in an acute ischemic stroke model by targeting astroglial and microglial function as well as improving neuronal survival strategies. Our findings signify the potential clinical feasibility of PUFA n3 therapeutic treatment in stroke and other acute neurological diseases.

  20. Neurological complications post-liver transplantation: impact of nutritional status. (United States)

    Bemeur, Chantal


    Nutritional status is significantly altered in patients with end-stage liver disease (cirrhosis). Malnutrition is a common complication of cirrhosis and is known to be associated with a greater risk of post-operative complications and mortality, especially following liver transplantation. Neurological complications occur frequently after transplant and the nature and extent of these complications may relate to nutritional deficits such as protein-calorie malnutrition as well as vitamin and micronutrient deficiencies. A consensus document from the International Society on Hepatic Encephalopathy and Nitrogen metabolism (ISHEN) has been established in order to address these concerns. Careful assessment of nutritional status followed by prompt treatment of nutritional deficits has the potential to impact on transplant outcome and, in particular, on post-transplant neurological disorders in patients with cirrhosis.

  1. Endocrine disorders and the neurologic manifestations. (United States)

    Yu, Jeesuk


    The nervous system and the endocrine system are closely interrelated and both involved intimately in maintaining homeostasis. Endocrine dysfunctions may lead to various neurologic manifestations such as headache, myopathy, and acute encephalopathy including coma. It is important to recognize the neurologic signs and symptoms caused by the endocrine disorders while managing endocrine disorders. This article provides an overview of the neurologic manifestations found in various endocrine disorders that affect pediatric patients. It is valuable to think about 'endocrine disorder' as a cause of the neurologic manifestations. Early diagnosis and treatment of hormonal imbalance can rapidly relieve the neurologic symptoms. Better understanding of the interaction between the endocrine system and the nervous system, combined with the knowledge about the pathophysiology of the neurologic manifestations presented in the endocrine disorders might allow earlier diagnosis and better treatment of the endocrine disorders.

  2. Transcranial amelioration of inflammation and cell death after brain injury (United States)

    Roth, Theodore L.; Nayak, Debasis; Atanasijevic, Tatjana; Koretsky, Alan P.; Latour, Lawrence L.; McGavern, Dorian B.


    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.

  3. Aphasia, Just a Neurological Disorder?

    Mehmet Ozdemir


    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.

  4. Neurological problems of jazz legends. (United States)

    Pearl, Phillip L


    A variety of neurological problems have affected the lives of giants in the jazz genre. Cole Porter courageously remained prolific after severe leg injuries secondary to an equestrian accident, until he succumbed to osteomyelitis, amputations, depression, and phantom limb pain. George Gershwin resisted explanations for uncinate seizures and personality change and herniated from a right temporal lobe brain tumor, which was a benign cystic glioma. Thelonious Monk had erratic moods, reflected in his pianism, and was ultimately mute and withdrawn, succumbing to cerebrovascular events. Charlie Parker dealt with mood lability and drug dependence, the latter emanating from analgesics following an accident, and ultimately lived as hard as he played his famous bebop saxophone lines and arpeggios. Charles Mingus hummed his last compositions into a tape recorder as he died with motor neuron disease. Bud Powell had severe posttraumatic headaches after being struck by a police stick defending Thelonious Monk during a Harlem club raid.

    Guiraud-Chaumeil, Bernard; Pariente, Jérémie; Albucher, Jean-François; Loubinoux, Isabelle; Chollet, François


    Stroke is one of the most common affliction of patients with neurological symptoms. Rehabilitation of stroke patients is a difficult task. Our knowledge on rehabilitation has recently improved with the emergence of data from new neuroimaging techniques. A prospective, double blind, cross over, placebo, controlled study on 8 patients with pure motor hemiparesia, is conducted to determine the influence of a single dose of fluoxetine on motor performance and cerebral activation of patients recovering from stroke. Each patient undergoes two functional magnetic resonance imaging (fMRI) examinations, one under fluoxetine and one under placebo. A single dose of fluoxetine is enough to modulate cerebral sensori-motor activation and significantly improves motor skills of the affected side. Further studies are required to investigate the effect of chronic administration of fluoxetine on motor function.

    Full Text Available Background: The transition from fetal to neonatal life during birth is difficult for all babies. We aim to analyze the demography, clinical presentation, causes, and outcome of neurologically distressed newborns. Materials and Methods: We reviewed a total of 615 newborns files admitted with life threatening condition. Amongst them, 453 had presented neurological distress syndrome. Only cases with severe neurological impairment (Apgar Score System [ASS] ≤6 with no other associated injury were included in the study group. The study covered a period from January to December 2011 and located in pediatric intensive care unit. The information regarding clinical presentation, condition of birth, causes of distress, and outcome were analyzed. Neonate examination had been conducted by neonatologist and pediatric neurologist. Results: The sample included 272/453 (60.04% males and 181/453 (39.96% females. Newborns were aged from 1 to 14 days. The incidence of neurological distress amongst all admissions was 453/615 (73.65%. Clinical signs were weakness of primary reflexes (86.70%, non reactivity (78.19%, flaccid muscle tone (59.49% and impaired consciousness (32.29%. On Apgar score, 73 (20.68% had a score from 0 to 3; 234 (66.29% had a score 4-6 in the first minute of life. A total of 307 (86.97% newborns had been resuscitated at birth during the first five minutes. Death rate was 35.69%. Asphyxia (51.27% and neonatal infection (43.34% were the most common causes of death. Conclusion: These results show that much effort remains to be done in obstetric care, resuscitation management and improvement in neonatal infection care.

    Sanjay Pandey


    Full Text Available The burden of neurological illness is much higher in developing countries. Neurological disorders in these countries are mainly due to poverty and malnutrition. Spectrums of diseases are also different in comparison with developed countries. Lack of resources, ignorance, and overpopulation make it very difficult and challenging to tackle this problem. Majority of the patients are seen by general practitioners who have little knowledge about neurological illnesses. Most of the countries have very few or no neurologist. There is a greater need of taking neurological care at primary care level where majority of the patients struggle with epilepsy, stroke and neuroinfections.

    Full Text Available Hyponatremia is the commonest electrolyte disturbance encountered in the neurological and neurosurgical intensive care units. It can present with signs and symptoms mimicking a neurological disease and can worsen the existing neurological deficits. Hyponatremia in neurological disorders is usually of the hypo-osmolar type caused either due to the Syndrome of Inappropriate Secretion of Anti Diuretic Hormone (SIADH or Cerebral Salt Wasting Syndrome (CSWS. It is important to distinguish between these two disorders, as the treatment of the two differ to a large extent. In SIADH, the fluid intake is restricted, whereas in CSWS the treatment involves fluid and salt replacement.

  16. Telemedicine in neurology: underutilized potential. (United States)

    Misra, U K; Kalita, J; Mishra, S K; Yadav, R K


    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.

    Twenty-two patients with brucella spondylitis and neurobrucellosis were studied during a 2-year period. The diagnosis was based on history of exposure, compatible signs and symptoms, high antibody titre and/or positive culture of a clinical specimen(s). Spondylitis was confirmed by plain radiographs, bone scan, CT and in some cases by histology. Neurobrucellosis was confirmed by CSF examination and culture, myelography, NCV, EMG and CT head. The spondylitis was early in 4 cases, chronic active in 12, smouldering "partially healed" in 3 and healed in 3 cases. Of these, 15 patients (68%) had neurological complications of various types. Plain radiographs were not a good index of activity of spondylitis. Tc99 bone scan was not specific and it remained positive long after the completion of therapy. CT was superior in revealing details of bone destruction, soft tissue swelling and entrapment of nerve roots and cord. The 3 modalities were complementary. Spondylitis is commonly associated with neurobrucellosis and symptoms of one may over shadow those of the other and in some cases neurobrucellosis may be subclinical. In all cases of spondylitis, a thorough search for neurobrucellosis should be made and vice versa. Prolonged treatment with a combination of 3 anti-brucella drugs is recommended and prolonged follow-up is necessary.

  19. Addressing neurological disorders with neuromodulation. (United States)

    Oluigbo, Chima O; Rezai, Ali R


    Neurological disorders are becoming increasingly common in developed countries as a result of the aging population. In spite of medications, these disorders can result in progressive loss of function as well as chronic physical, cognitive, and emotional disability that ultimately places enormous emotional and economic on the patient, caretakers, and the society in general. Neuromodulation is emerging as a therapeutic option in these patients. Neuromodulation is a field, which involves implantable devices that allow for the reversible adjustable application of electrical, chemical, or biological agents to the central or peripheral nervous system with the objective of altering its functioning with the objective of achieving a therapeutic or clinically beneficial effect. It is a rapidly evolving field that brings together many different specialties in the fields of medicine, materials science, computer science and technology, biomedical, and neural engineering as well as the surgical or interventional specialties. It has multiple current and emerging indications, and an enormous potential for growth. The main challenges before it are in the need for effective collaboration between engineers, basic scientists, and clinicians to develop innovations that address specific problems resulting in new devices and clinical applications.

    Full Text Available The authors report on six cases of gluten-sensitivity, also defined non-celiac gluten sensitivity, characterized by abdominal features (diarrhea, bloating, pain, genetic positivity for predisposition to celiac disease (DQB1* 02 in all cases; DQA1*05 in three; DQA1*02 in two, DQB1*03 in two, negative anti-t-Transglutaminase antibodies, normal mucosa on biopsy in four cases, type 1 of Marsh in one case. The subjects presented frequent central nervous system (CNS symptoms: headache in three patients, somnolence in one, electroencephalogram aspecific alterations in three (in two of them with previous seizures, leptomeningeal cyst in one, intracranial calcification in one, cerebral gliosis in two. After a gluten-free diet, all intestinal and clinical CNS features remitted, but re-appeared after gluten reintroduction. On the basis of the neurological signs, the authors stress the relevance of immune innate system in the pathogenesis of these cases with possible subsequent evolution on immune adaptive system involvement.

    Li, Xinning; Curry, Emily J; Blais, Micah; Ma, Richard; Sungarian, Arno S


    The annual incidence of traumatic spinal cord injury worldwide is estimated to be 35 patients per million. Nonmissile penetrating spinal injuries most commonly occur in the thoracic region, and the majority has neurologic deficits on admission. The management of patients who lack neurologic deficits is controversial due to the risk of neurologic status alteration intraoperatively. However, failure to intervene increases the risk of infection, delayed onset of neurologic deficits, and worsening functional outcome.A 17-year-old boy presented with an intradural T7-T8 knife penetration injury to the spinal cord with no neurologic deficit. Rapid surgical intervention was critical because the knife was lodged between the 2 hemispheres of the spinal cord. The patient was intubated in the lateral position, transferred to the prone position on a Jackson table, and underwent surgical decompression with laminectomy 1 level above and below the injury site, removal of the knife blade in the original path of trajectory, and repair of the dural tear with a collagen matrix. The patient sustained no neurologic sequelae from the penetrating knife injury. He was able to ambulate at discharge and had no complications. To our knowledge, this is the only report of a patient with intradural spinal cord penetration by a foreign object (knife blade) presenting with a normal neurologic preoperative examination that persisted throughout the course of postoperative care.

    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.

  3. Neurological injuries and extracorporeal membrane oxygenation: the challenge of the new ECMO era. (United States)

    Martucci, Gennaro; Lo Re, Vincenzina; Arcadipane, Antonio


    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.

  4. Clinical Outcome Measures in Chiari I Malformation. (United States)

    Yarbrough, Chester K; Greenberg, Jacob K; Park, Tae Sung


    Chiari malformation type 1 (CM-I) is a common and often debilitating neurologic disease. Reliable evaluation of treatments has been hampered by inconsistent use of clinical outcome measures. A variety of outcome measurement tools are available, although few have been validated in CM-I. The recent development of the Chicago Chiari Outcome Scale and the Chiari Symptom Profile provides CM-I-specific instruments to measure outcomes in adults and children, although validation and refinement may be necessary.

  6. Ultrasound treatment of neurological diseases--current and emerging applications. (United States)

    Leinenga, Gerhard; Langton, Christian; Nisbet, Rebecca; Götz, Jürgen


    Like cardiovascular disease and cancer, neurological disorders present an increasing challenge for an ageing population. Whereas nonpharmacological procedures are routine for eliminating cancer tissue or opening a blocked artery, the focus in neurological disease remains on pharmacological interventions. Setbacks in clinical trials and the obstacle of access to the brain for drug delivery and surgery have highlighted the potential for therapeutic use of ultrasound in neurological diseases, and the technology has proved useful for inducing focused lesions, clearing protein aggregates, facilitating drug uptake, and modulating neuronal function. In this Review, we discuss milestones in the development of therapeutic ultrasound, from the first steps in the 1950s to recent improvements in technology. We provide an overview of the principles of diagnostic and therapeutic ultrasound, for surgery and transient opening of the blood-brain barrier, and its application in clinical trials of stroke, Parkinson disease and chronic pain. We discuss the promising outcomes of safety and feasibility studies in preclinical models, including rodents, pigs and macaques, and efficacy studies in models of Alzheimer disease. We also consider the challenges faced on the road to clinical translation.

  7. Neurological AdverseEffects after Radiation Therapyfor Stage II Seminoma

    Directory of Open Access Journals (Sweden)

    Liv Ebbeskov Lauritsen


    Full Text Available 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 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.

BI data were collected and analyzed.Results: The BI score was found to have increased in follow-up assessments (P = 0.048. No correlation was found between the degree of spasticity and the BI score.Conclusion: The specific injection of Botox in patients with neurologic lesions was not strongly correlated with a significant functional outcome according to the BI. The results of this study suggest that clinicians need to look at other measurement scales for the assessment of significant outcomes of Botox in the rehabilitation process after neurologic lesions.Keywords: botulinum toxin type A, spasticity, stroke, multiple sclerosis

  9. The global perspective on neurology training: the World Federation of Neurology survey. (United States)

    Steck, Andreas; Struhal, Walter; Sergay, Stephen M; Grisold, Wolfgang


    This World Federation of Neurology (WFN) study aimed to characterize the status quo of post-graduate neurology training throughout the world and enable a better orientation on global training in neurology. Basic data on training curricula and working conditions of neurology residents and neurologists in 39 countries worldwide were evaluated. Our data show considerable differences in manpower and training, but a continuous improvement within the last 10 years of observation. Worldwide a spread of interim evaluations and final examinations of different types are used. Online resources will undoubtedly profoundly change skill and knowledge acquisition and training practices in Neurology in the coming years.

  10. Music therapy in neurological rehabilitation settings

    Directory of Open Access Journals (Sweden)

    Elżbieta Galińska


    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.

  12. Effects of music and music therapy on mood in neurological patients. (United States)

    Raglio, Alfredo; Attardo, Lapo; Gontero, Giulia; Rollino, Silvia; Groppo, Elisabetta; Granieri, Enrico


    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.

  13. [Neurological disease and facial recognition]. (United States)

    Kawamura, Mitsuru; Sugimoto, Azusa; Kobayakawa, Mutsutaka; Tsuruya, Natsuko


    To discuss the neurological basis of facial recognition, we present our case reports of impaired recognition and a review of previous literature. First, we present a case of infarction and discuss prosopagnosia, which has had a large impact on face recognition research. From a study of patient symptoms, we assume that prosopagnosia may be caused by unilateral right occipitotemporal lesion and right cerebral dominance of facial recognition. Further, circumscribed lesion and degenerative disease may also cause progressive prosopagnosia. Apperceptive prosopagnosia is observed in patients with posterior cortical atrophy (PCA), pathologically considered as Alzheimer's disease, and associative prosopagnosia in frontotemporal lobar degeneration (FTLD). Second, we discuss face recognition as part of communication. Patients with Parkinson disease show social cognitive impairments, such as difficulty in facial expression recognition and deficits in theory of mind as detected by the reading the mind in the eyes test. Pathological and functional imaging studies indicate that social cognitive impairment in Parkinson disease is possibly related to damages in the amygdalae and surrounding limbic system. The social cognitive deficits can be observed in the early stages of Parkinson disease, and even in the prodromal stage, for example, patients with rapid eye movement (REM) sleep behavior disorder (RBD) show impairment in facial expression recognition. Further, patients with myotonic dystrophy type 1 (DM 1), which is a multisystem disease that mainly affects the muscles, show social cognitive impairment similar to that of Parkinson disease. Our previous study showed that facial expression recognition impairment of DM 1 patients is associated with lesion in the amygdalae and insulae. Our study results indicate that behaviors and personality traits in DM 1 patients, which are revealed by social cognitive impairment, are attributable to dysfunction of the limbic system.

  14. [Neurological diseases in the aged]. (United States)

    Kameyama, M


    In this paper, I described clinical and basic problems on neurology of the aged patients. These studies have been done in various institutions with many co-workers. 1) A PET study revealed some age differences on CBF, CMRO2, or CMRgl. But these results are not so rigid in which much of individual variations should be considered in interpretation. Calendar age is not always compatible to biological age. 2) Saccular aneurysms in the brain artery were found in 7.3% of 1200 routine autopsy series of the aged subjects. Aneurysms with external diameter exceeding 6 mm had been fatally ruptured in 14 (78%) of 18 subjects. 3) Variations of the pyramidal crossing are found responsible for bizarre clinical manifestations. Non-crossing component was more prominent in the right pyramidal tract; consequently, right pyramidal tracts including ventral and lateral one seemed to have more extensive representation in the spinal cord level. 4) I123-IMP SPECT study showed a reduced uptake in the area 4 or area 4-6 of the ALS patients. 5) I introduced a new simplified Wartenberg's maneuver, which is useful for detection of subtle pyramidal dysfunctions. 6) Cases with central pontine myelinolysis and those of paraneoplastic syndrome were presented with an emphasis on their patho-chemical mechanisms. 7) Lewis-Sumner syndrome showing multifocal persistent conduction block is not rare in the aged, in which we have already had some useful therapeutic methods. 8) Dementia complicated with neurodegenerative disease was discussed on its clinical and chemical features of mental disturbances. In ALS-dementia, CSF-homovanilic acid reduced significantly than in the control and L-dopa was effective in some patients. 9) Vascular and Alzheimer-type dementias were presented and discussed on their pathogenetic mechanism according to our recent studies with review of literature.

  15. Adult Hip Flexion Contracture due to Neurological Disease: A New Treatment Protocol—Surgical Treatment of Neurological Hip Flexion Contracture

    Directory of Open Access Journals (Sweden)

    Alberto Nicodemo


    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.

  16. Chapter 44: history of neurology in Italy. (United States)

    Bentivoglio, Marina; Mazzarello, Paolo


    The chapter starts from the Renaissance (although the origins of Italian neurology can be traced back to the Middle Ages), when treatises of nervous system physiopathology still followed Hippocratic and Galenic "humoral" theories. In Italy, as elsewhere in Europe, the concepts of humoral pathology were abandoned in the 18th century, when neurology was influenced by novel trends. Neurology acquired the status of clinical discipline (as "clinic of mental diseases") after national reunification (declared in 1861 but completed much later). At the end of the 19th and first decades of the 20th century, eminent Italian "neuropsychiatrists" (including, among many others, Ugo Cerletti, who introduced electroconvulsive shock therapy in 1938) stimulated novel knowledge and approaches, "centers of excellence" flourished, and "Neurological Institutes" were founded. In the first half of the 20th century, the history of Italian neurology was dominated by World Wars I and II (which stimulated studies on the wounded) and the fascist regime in-between the Wars (when the flow of information was instead very limited). Italy became a republic in 1946, and modern neurology and its distinction from psychiatry were finally promoted. The chapter also provides detailed accounts of scientific societies and journals dedicated to the neurological sciences in Italy.

    Tapia, Jorge


    C. Miller Fisher MD, one of the great neurologists in the 20th century, died in April 2012. Born in Canada, he studied medicine at the University of Toronto. As a Canadian Navy medical doctor he participated in World War II and was a war prisoner from 1941 to 1944. He did a residency in neurology at the Montreal Neurological Institute between 1946 and 1948, and later on was a Fellow in Neurology and Neuropathology at the Boston City Hospital. In 1954 he entered the Massachusetts General Hospital as a neurologist and neuropathologist, where he remained until his retirement, in 2005. His academic career ended as Professor Emeritus at Harvard University. His area of special interest in neurology was cerebrovascular disease (CVD). In 1954 he created the first Vascular Neurology service in the world and trained many leading neurologists on this field. His scientific contributions are present in more than 250 publications, as journal articles and book chapters. Many of his articles, certainly not restricted to CVD, were seminal in neurology. Several concepts and terms that he coined are currently used in daily clinical practice. The chapters on CVD, in seven consecutive editions of Harrison's Internal Medicine textbook, are among his highlights. His death was deeply felt by the neurological community.

  18. Ionotropic GABA and Glutamate Receptor Mutations and Human Neurologic Diseases. (United States)

    Yuan, Hongjie; Low, Chian-Ming; Moody, Olivia A; Jenkins, Andrew; Traynelis, Stephen F


    The advent of whole exome/genome sequencing and the technology-driven reduction in the cost of next-generation sequencing as well as the introduction of diagnostic-targeted sequencing chips have resulted in an unprecedented volume of data directly linking patient genomic variability to disorders of the brain. This information has the potential to transform our understanding of neurologic disorders by improving diagnoses, illuminating the molecular heterogeneity underlying diseases, and identifying new targets for therapeutic treatment. There is a strong history of mutations in GABA receptor genes being involved in neurologic diseases, particularly the epilepsies. In addition, a substantial number of variants and mutations have been found in GABA receptor genes in patients with autism, schizophrenia, and addiction, suggesting potential links between the GABA receptors and these conditions. A new and unexpected outcome from sequencing efforts has been the surprising number of mutations found in glutamate receptor subunits, with the GRIN2A gene encoding the GluN2A N-methyl-d-aspartate receptor subunit being most often affected. These mutations are associated with multiple neurologic conditions, for which seizure disorders comprise the largest group. The GluN2A subunit appears to be a locus for epilepsy, which holds important therapeutic implications. Virtually all α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor mutations, most of which occur within GRIA3, are from patients with intellectual disabilities, suggesting a link to this condition. Similarly, the most common phenotype for kainate receptor variants is intellectual disability. Herein, we summarize the current understanding of disease-associated mutations in ionotropic GABA and glutamate receptor families, and discuss implications regarding the identification of human mutations and treatment of neurologic diseases.

    Treatment of infectious diarrheas remains a challenge, particularly in immunocompromised patients in whom infections usually persist and resultant diarrhea is often severe and protracted. Children with infectious diarrhea who become dehydrated are normally treated with oral or intravenous rehydration therapy. Although rehydration therapy can replace the loss of fluid, it does not ameliorate diarrhea. Thus, over the past decades, there has been continuous effort to search for ways to safely st...

  20. [Neurological complications of inflammatory bowel diseases]. (United States)

    Cieplik, N; Stangel, M; Bachmann, O


    Inflammatory bowel diseases, such as Crohn's disease, ulcerative colitis, autoantibody driven celiac disease and infectious Whipple's disease can all be associated with neurological symptoms. The neurological manifestation may occur even before the gastrointestinal symptoms or the enteropathic symptoms can even be absent as in celiac disease. These diseases can be caused by malresorption and lack of vitamins due to enteral inflammation as well as (auto-)immunological mechanisms and drug-associated side effects. Thus, inflammatory bowel diseases have to be considered in the differential diagnosis. In this review the most common neurological manifestations of these diseases will be described as well as the diagnostic approach.

  2. Brain microvascular endothelial cell transplantation ameliorates ischemic white matter damage. (United States)

    Puentes, Sandra; Kurachi, Masashi; Shibasaki, Koji; Naruse, Masae; Yoshimoto, Yuhei; Mikuni, Masahiko; Imai, Hideaki; Ishizaki, Yasuki


    Ischemic insults affecting the internal capsule result in sensory-motor disabilities which adversely affect the patient's life. Cerebral endothelial cells have been reported to exert a protective effect against brain damage, so the transplantation of healthy endothelial cells might have a beneficial effect on the outcome of ischemic brain damage. In this study, endothelin-1 (ET-1) was injected into the rat internal capsule to induce lacunar infarction. Seven days after ET-1 injection, microvascular endothelial cells (MVECs) were transplanted into the internal capsule. Meningeal cells or 0.2% bovine serum albumin-Hank's balanced salt solution were injected as controls. Two weeks later, the footprint test and histochemical analysis were performed. We found that MVEC transplantation improved the behavioral outcome based on recovery of hind-limb rotation angle (P<0.01) and induced remyelination (P<0.01) compared with the control groups. Also the inflammatory response was repressed by MVEC transplantation, judging from fewer ED-1-positive activated microglial cells in the MVEC-transplanted group than in the other groups. Elucidation of the mechanisms by which MVECs ameliorate ischemic damage of the white matter may provide important information for the development of effective therapies for white matter ischemia.

  3. Clinical utility of early amplitude integrated EEG in monitoring term newborns at risk of neurological injury

    Paulina A. Toso


    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 Inborn errors of organic acid metabolism are relatively recently recognized diseases with a wide spectrum of clinical signs and symptoms: ranging from asymptomatic, normal appearing children to death during first few days of life.In my presentation I will try to explain some of the most common clinical presentation of these disorder with stress on neurologic findings. Organic acidemia usually have three clinical manifestations Severe neonatal form, Intermittent late-onset form and chronic progressive form. Recurrent coma, The main feature of these disorders is due to accumulation of toxic metabolites in Central Nervous system with direct effect on the function, while chronic accumulation of these materials may interfere with CNS development or cerebral metabolism leading to developmental delay.Severe neonatal formsFollowing a symptom free interval of a few days from birth, poor sucking and difficult feeding appears in the newborn, followed by unexplained and progressive coma. Seizures may appear during the course of the disease and EEG may show a burst-suppression pattern. During this stage most infants have axial hypotonia with peripheral dystonia, choreoathetosis, episodic opisthotonus and some repetitive bicycling and boxing movements.Associated biochemical abnormalities including metabolic acidosis, ketonuria and hyperammonemia also is usually present. The overall short-term prognosis with recent advances in medical care is improving. But later in life acute intercurrent episodes triggered by a stress often occur, which can be occasionally fatal.bulging fontanelle and cerebral edema may mimic CNS infection in these babies.Intermittent late-onset formsRecurrent attacks of coma or lethargy with ataxia can occur in childhood or even in adolescence or adulthood. These episodes may be frequent, though in between these the child is entirely normal. These attacks are precipitated by conditions that enhance protein catabolism (trauma, infection etc

    Zehra Hatipoglu


    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.

  10. Sporadic hemiplegic migraine with permanent neurological deficits. (United States)

    Schwedt, Todd J; Zhou, Jiying; Dodick, David W


    By definition, the neurologic impairments of hemiplegic migraine are reversible. However, a few cases of permanent neurologic deficits associated with hemiplegic migraine have been reported. Herein, we present the case of a patient with permanent impairments because of hemiplegic migraine despite normalization of associated brain magnetic resonance imaging abnormalities. Cases like these suggest the need to consider aggressive prophylactic therapy for patients with recurrent hemiplegic migraine attacks.

  12. EEG in Sarcoidosis Patients Without Neurological Findings. (United States)

    Bilgin Topçuoğlu, Özgür; Kavas, Murat; Öztaş, Selahattin; Arınç, Sibel; Afşar, Gülgün; Saraç, Sema; Midi, İpek


    Sarcoidosis is a multisystem granulomatous disease affecting nervous system in 5% to 10% of patients. Magnetic resonance imaging (MRI) is accepted as the most sensitive method for detecting neurosarcoidosis. However, the most common findings in MRI are the nonspecific white matter lesions, which may be unrelated to sarcoidosis and can occur because of hypertension, diabetes mellitus, smoking, and other inflammatory or infectious disorders, as well. Autopsy studies report more frequent neurological involvement than the ante mortem studies. The aim of this study is to assess electroencephalography (EEG) in sarcoidosis patients without neurological findings in order to display asymptomatic neurological dysfunction. We performed EEG on 30 sarcoidosis patients without diagnosis of neurosarcoidosis or prior neurological comorbidities. Fourteen patients (46.7%) showed intermittant focal and/or generalized slowings while awake and not mentally activated. Seven (50%) of these 14 patients with EEG slowings had nonspecific white matter changes while the other half showed EEG slowings in the absence of MRI changes. We conclude that EEG slowings, when normal variants (psychomotor variant, temporal theta of elderly, frontal theta waves) are eliminated, may be an indicator of dysfunction in brain activity even in the absence of MRI findings. Hence, EEG may contribute toward detecting asymptomatic neurological dysfunction or probable future neurological involvement in sarcoidosis patients.

  13. Neurological Disorders in Adult Celiac Disease

    Directory of Open Access Journals (Sweden)

    Hugh J Freeman


    Full Text Available Celiac disease may initially present as a neurological disorder. Alternatively, celiac disease may be complicated by neurological changes. With impaired nutrient absorption, different deficiency syndromes may occur and these may be manifested clinically with neurological changes. However, in patients with deficiency syndromes, extensive involvement of the small intestine with celiac disease is often evident. There are a number of reports of celiac disease associated with neuropathy, ataxia, dementia and seizure disorder. In these reports, there is no clear relationship with nutrient deficiency and a precise mechanism for the neurological changes has not been defined. A small number of patients have been reported to have responded to vitamin E administration, but most do not. In some, gluten antibodies have also been described, especially in those with ataxia, but a consistent response to a gluten-free diet has not been defined. Screening for celiac disease should be considered in patients with unexplained neurological disorders, including ataxia and dementia. Further studies are needed, however, to determine if a gluten-free diet will lead to improvement in the associated neurological disorder.

  14. Perimenopause as a neurological transition state. (United States)

    Brinton, Roberta D; Yao, Jia; Yin, Fei; Mack, Wendy J; Cadenas, Enrique


    Perimenopause is a midlife transition state experienced by women that occurs in the context of a fully functioning neurological system and results in reproductive senescence. Although primarily viewed as a reproductive transition, the symptoms of perimenopause are largely neurological in nature. Neurological symptoms that emerge during perimenopause are indicative of disruption in multiple estrogen-regulated systems (including thermoregulation, sleep, circadian rhythms and sensory processing) and affect multiple domains of cognitive function. Estrogen is a master regulator that functions through a network of estrogen receptors to ensure that the brain effectively responds at rapid, intermediate and long timescales to regulate energy metabolism in the brain via coordinated signalling and transcriptional pathways. The estrogen receptor network becomes uncoupled from the bioenergetic system during the perimenopausal transition and, as a corollary, a hypometabolic state associated with neurological dysfunction can develop. For some women, this hypometabolic state might increase the risk of developing neurodegenerative diseases later in life. The perimenopausal transition might also represent a window of opportunity to prevent age-related neurological diseases. This Review considers the importance of neurological symptoms in perimenopause in the context of their relationship to the network of estrogen receptors that control metabolism in the brain.

    Babany, F; Hamdoun, S; Denys, P; Amarenco, G


    Sexual disorders are common after neurological diseases. The reconstruction of sexuality is a major issue after neurologic disability. Why is this topic not covered in rehabilitation medicine except specialized service? The aim of this pilot study was to assess the perception of the healthcare professionals (HCPs) and to understand why this topic was not addressed. We conducted a pilot, observational, monocentric study from February to March 2016 in HCPs from a neurologic rehabilitation hospital unit.

  16. Acupuncture Improved Neurological Recovery after Traumatic Brain Injury by Activating BDNF/TrkB Pathway (United States)

    Li, Xiaohong; Chen, Chong; Yang, Xiping; Wang, Jingjing; Zhao, Ming-liang; Sun, Hongtao


    How to promote neural repair following traumatic brain injury (TBI) has long been an intractable problem. Although acupuncture has been demonstrated to facilitate the neurological recovery, the underlying mechanism is elusive. Brain-derived neurotrophic factor (BDNF) exerts substantial protective effects for neurological disorders. In this study, we found that the level of BDNF and tropomyosin receptor kinase B (TrkB) was elevated spontaneously after TBI and reached up to the peak at 12 h. Nevertheless, this enhancement is quickly declined to the normal at 48 h. After combined stimulation at the acupoints of Baihui, Renzhong, Hegu, and Zusanli, we found that BDNF and TrkB were still significantly elevated at 168 h. We also observed that the downstream molecular p-Akt and p-Erk1/2 were significantly increased, suggesting that acupuncture could persistently activate the BDNF/TrkB pathway. To further verify that acupuncture improved recovery through activating BDNF/TrkB pathway, K252a (specific inhibitor of TrkB) was treated by injection stereotaxically into lateral ventricle. We observed that K252a could significantly prevent the acupuncture-induced amelioration of motor, sensation, cognition, and synaptic plasticity. These data indicated that acupuncture promoted the recovery of neurological impairment after TBI by activating BDNF/TrkB signaling pathway, providing new molecular mechanism for understanding traditional therapy of acupuncture.

  17. Neurology in a globalizing world: World Congress of Neurology, Vienna, 2013. (United States)

    Hachinski, Vladimir


    The World Congress of Neurology (figure 1) theme "Neurology in a Globalizing World" acknowledges that science and increasingly medicine and neurology are becoming globalized. The best way to manage change is to shape it. It is becoming increasingly clear that brain diseases, particularly stroke and dementia, are projected to rise at a rate that could overwhelm our clinics and hospitals. Hence a new emphasis on prevention and the need to work across disciplines beyond our traditional roles. Neurologists are the guardians of the brain and need to take the lead role in advancing new approaches in stemming the tide of neurologic diseases.

  18. Household food insecurity and symptoms of neurologic disorder in Ethiopia: An observational analysis

    Directory of Open Access Journals (Sweden)

    Tessema Fasil


    Full Text Available Abstract Background Food insecurity (FI has been shown to be associated with poor health both in developing and developed countries. Little is known about the relation between FI and neurological disorder. We assessed the relation between FI and risk for neurologic symptoms in southwest Ethiopia. Methods Data about food security, gender, age, household assets, and self-reported neurologic symptoms were collected from a representative, community-based sample of adults (N = 900 in Jimma Zone, Ethiopia. We calculated univariate statistics and used bivariate chi-square tests and multivariate logistic regression models to assess the relation between FI and risk of neurologic symptoms including seizures, extremity weakness, extremity numbness, tremors/ataxia, aphasia, carpal tunnel syndrome, vision dysfunction, and spinal pain. Results In separate multivariate models by outcome and gender, adjusting for age and household socioeconomic status, severe FI was associated with higher odds of seizures, movement abnormalities, carpal tunnel, vision dysfunction, spinal pain, and comorbid disorders among women. Severe FI was associated with higher odds of seizures, extremity numbness, movement abnormalities, difficulty speaking, carpal tunnel, vision dysfunction, and comorbid disorders among men. Conclusion We found that FI was associated with symptoms of neurologic disorder. Given the cross-sectional nature of our study, the directionality of these associations is unclear. Future research should assess causal mechanisms relating FI to neurologic symptoms in sub-Saharan Africa.

  19. Amelioration of experimental autoimmune encephalomyelitis through transplantation of placental derived mesenchymal stem cells (United States)

    Jiang, Hong; Zhang, Yuanyuan; Tian, Kewei; Wang, Beibei; Han, Shu


    Placental derived mesenchymal stem cells (PMSCs) have been suggested as a possible source of cells to treat multiple sclerosis (MS) due to their immunomodulatory functions, lack of ethical concerns, and potential to differentiate into neurons and oligodendrocytes. To investigate whether PMSCs share similar characteristics with embryonic mesenchymal stem cells (EMSCs), and if transplanted PMSCs have the ability to integrate and replace degenerated neural cells, we transplanted rat PMSCs and EMSCs into the central nervous system (CNS) of Lewis rats with experimental autoimmune encephalomyelitis (EAE), an animal model of MS. Our findings demonstrated that transplanted PMSCs, similar to EMSCs, were effective in decreasing infiltrating inflammatory cells, preserving axons, and ameliorating demyelination, thereby improving the neurological functions of animals. Moreover, both PMSCs and EMSCs had the ability to migrate into inflamed tissues and express neural–glial lineage markers. These findings suggest that PMSCs may replace EMSCs as a source of cells in MS stem cell therapy. PMID:28186117

  20. Pattern of neurological admissions in the tropics: Experience at Kano, Northwestern Nigeria

    Directory of Open Access Journals (Sweden)

    Owolabi L


    Full Text Available Background: Kano is the most populated state in Nigeria with a population totaling 9,383,682. The pattern of neurologic diseases in this area is not known. Objective: To determine the of pattern of neurologic diseases warranting admission in a tertiary hospital in Kano and compare it with those elsewhere in the country with the view to using the data generated as a baseline for planning purposes and for future studies. Materials and Methods: The medical records of all cases admitted with neurologic diseases in the Aminu Kano Teaching Hospital, Kano between January 2005 and September 2008, were retrospectively reviewed and the frequency of neurologic diseases, sex, age, and outcome of these diseases analyzed. Result: Stroke, predominantly ischemic, accounted for 77.6% of the neurological cases for the period of study. Central nervous system infections, comprising mainly of meningitis and tetanus, accounted for 6.6% (64 and 3% (29 of cases, respectively. The myelopathies were the cause of neurologic admissions in 5.4% (53 with paraplegia and quadriplegia resulting from myelopathies accounting for 5% (49 and 0.4% (4 of the cases. Hypertensive encephalopathy and status epilepticus as the causes of admissions accounted for 1.6% each. Gullain Barre syndrome, Parkinson′s disease, and cerebral malaria were relatively rare causes of neurologic admissions in this study. The average duration of hospitalization was 25 days, and regarding outcome, 219 (22.4% of these cases died. Conclusions: Stroke appeared to be the most common neurologic admission and the most common cause of neurologic and medical death in Kano as observed in other regions of the country and a little over one-fifths of stroke patients die. Central nervous system infections mainly meningitis and tetanus are the next common cause of admission. In view of these findings, the provision of a regional stroke unit, the improvement of the sanitary conditions of the home and environment; the

  1. The healthy cell bias of estrogen action: mitochondrial bioenergetics and neurological implications. (United States)

    Brinton, Roberta Diaz


    The 'healthy cell bias of estrogen action' hypothesis examines the role that regulating mitochondrial function and bioenergetics play in promoting neural health and the mechanistic crossroads that lead to divergent outcomes following estrogen exposure. Estrogen-induced signaling pathways in hippocampal and cortical neurons converge upon the mitochondria to enhance aerobic glycolysis coupled to the citric acid cycle, mitochondrial respiration and ATP generation. Convergence of estrogen-induced signaling onto mitochondria is also a point of vulnerability when activated in diseased neurons which exacerbates degeneration through increased load on dysregulated calcium homeostasis. As the continuum of neurological health progresses from healthy to unhealthy so too do the benefits of estrogen or hormone therapy. The healthy cell bias of estrogen action hypothesis provides a lens through which to assess disparities in outcomes across basic and clinical science and on which to predict outcomes of estrogen interventions for sustaining neurological health and preventing age-associated neurodegenerative diseases such as Alzheimer's.

  2. Smart homes for people with neurological disability: state of the art. (United States)

    Gentry, Tony


    Smart home technology can include environmental adaptations that allow remote control of home appliances, electronic communication, safety monitoring and automated task cueing, any of which may prove useful for people with neurological disability. This article outlines currently available smart home technologies, examines the burgeoning research in this area, discusses clinical and consumer resources and reviews ethical, funding and professional training considerations for smart home applications. I conclude that more outcomes-based research and collaboration among stakeholders is essential in order to establish guidance for designing, selecting and implementing individualized smart home solutions for those with neurological disability.

  3. Experimental evidence for growth factor treatment and function in certain neurological disorders. (United States)

    Springer, J E


    This issue focuses on the potential utilization or involvement of growth factors in Alzheimer's disease, amyotrophic lateral sclerosis, Parkinson's disease, and epilepsy. Certainly, the role of growth factors in other neurological disorders associated with stroke, trauma, and neurodegeneration needs to be considered. While there is no direct evidence to indicate that a neurological disorder is associated with the compromised function of a specific growth factor, the use of these molecules as therapeutic agents is justifiable. Undoubtedly, the outcome of current clinical trials will certainly influence future decisions on the use of growth factor therapies.

  4. Measles, mumps, rubella, and human parvovirus B19 infections and neurologic disease. (United States)

    Bale, James F


    While the systemic disorders associated with measles, mumps, and rubella viruses and human parvovirus B19 tend to be mild, each virus can produce potentially life-threatening neurologic disease in human hosts, especially when these viruses infect young children. Two of the viruses, rubella and parvovirus B19, can be vertically transmitted to fetuses during maternal infection and cause congenital infection. Neurologic complications are common after intrauterine infection with the rubella virus, a condition known as the congenital rubella syndrome. Two, measles and rubella viruses, can induce "slow viral" infections, serious, disorders that can occur several years after the initial exposure to the virus and typically have fatal outcomes.

  5. Standards in Neurological Rehabilitation, June 1997

    Directory of Open Access Journals (Sweden)

    Michael P. Barnes


    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

  6. Dengue: a new challenge for neurology

    Directory of Open Access Journals (Sweden)

    Marzia Puccioni-Sohler


    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.

  7. Neurological complications in chronic kidney disease

    Directory of Open Access Journals (Sweden)

    Ria Arnold


    Full Text Available Patients with chronic kidney disease (CKD are frequently afflicted with neurological complications. These complications can potentially affect both the central and peripheral nervous systems. Common neurological complications in CKD include stroke, cognitive dysfunction, encephalopathy, peripheral and autonomic neuropathies. These conditions have significant impact not only on patient morbidity but also on mortality risk through a variety of mechanisms. Understanding the pathophysiological mechanisms of these conditions can provide insights into effective management strategies for neurological complications. This review describes clinical management of neurological complications in CKD with reference to the contributing physiological and pathological derangements. Stroke, cognitive dysfunction and dementia share several pathological mechanisms that may contribute to vascular impairment and neurodegeneration. Cognitive dysfunction and dementia may be differentiated from encephalopathy which has similar contributing factors but presents in an acute and rapidly progressive manner and may be accompanied by tremor and asterixis. Recent evidence suggests that dietary potassium restriction may be a useful preventative measure for peripheral neuropathy. Management of painful neuropathic symptoms can be achieved by pharmacological means with careful dosing and side effect considerations for reduced renal function. Patients with autonomic neuropathy may respond to sildenafil for impotence. Neurological complications often become clinically apparent at end-stage disease, however early detection and management of these conditions in mild CKD may reduce their impact at later stages.

  8. Neurology referrals to a liaison psychiatry service.

    LENUS (Irish Health Repository)

    Fitzgerald, P


    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.

  9. Bacopa monniera leaf extract ameliorates hypobaric hypoxia induced spatial memory impairment. (United States)

    Hota, Sunil Kumar; Barhwal, Kalpana; Baitharu, Iswar; Prasad, Dipti; Singh, Shashi Bala; Ilavazhagan, Govindasamy


    Hypobaric hypoxia induced memory impairment has been attributed to several factors including increased oxidative stress, depleted mitochondrial bioenergetics, altered neurotransmission and apoptosis. This multifactorial response of the brain to hypobaric hypoxia limits the use of therapeutic agents that target individual pathways for ameliorating hypobaric hypoxia induced memory impairment. The present study aimed at exploring the therapeutic potential of a bacoside rich leaf extract of Bacopa monniera in improving the memory functions in hypobaric conditions. The learning ability was evaluated in male Sprague Dawley rats along with memory retrieval following exposure to hypobaric conditions simulating an altitude of 25,000 ft for different durations. The effect of bacoside administration on apoptosis, cytochrome c oxidase activity, ATP levels, and oxidative stress markers and on plasma corticosterone levels was investigated. Expression of NR1 subunit of N-methyl-d-aspartate receptors, neuronal cell adhesion molecules and was also studied along with CREB phosphorylation to elucidate the molecular mechanisms of bacoside action. Bacoside administration was seen to enhance learning ability in rats along with augmentation in memory retrieval and prevention of dendritic atrophy following hypoxic exposure. In addition, it decreased oxidative stress, plasma corticosterone levels and neuronal degeneration. Bacoside administration also increased cytochrome c oxidase activity along with a concomitant increase in ATP levels. Hence, administration of bacosides could be a useful therapeutic strategy in ameliorating hypobaric hypoxia induced cognitive dysfunctions and other related neurological disorders.

    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.

  13. Contemporary approach to neurologic prognostication of coma after cardiac arrest. (United States)

    Ben-Hamouda, Nawfel; Taccone, Fabio S; Rossetti, Andrea O; Oddo, Mauro


    Coma after cardiac arrest (CA) is an important cause of admission to the ICU. Prognosis of post-CA coma has significantly improved over the past decade, particularly because of aggressive postresuscitation care and the use of therapeutic targeted temperature management (TTM). TTM and sedatives used to maintain controlled cooling might delay neurologic reflexes and reduce the accuracy of clinical examination. In the early ICU phase, patients' good recovery may often be indistinguishable (based on neurologic examination alone) from patients who eventually will have a poor prognosis. Prognostication of post-CA coma, therefore, has evolved toward a multimodal approach that combines neurologic examination with EEG and evoked potentials. Blood biomarkers (eg, neuron-specific enolase [NSE] and soluble 100-β protein) are useful complements for coma prognostication; however, results vary among commercial laboratory assays, and applying one single cutoff level (eg, > 33 μg/L for NSE) for poor prognostication is not recommended. Neuroimaging, mainly diffusion MRI, is emerging as a promising tool for prognostication, but its precise role needs further study before it can be widely used. This multimodal approach might reduce false-positive rates of poor prognosis, thereby providing optimal prognostication of comatose CA survivors. The aim of this review is to summarize studies and the principal tools presently available for outcome prediction and to describe a practical approach to the multimodal prognostication of coma after CA, with a particular focus on neuromonitoring tools. We also propose an algorithm for the optimal use of such multimodal tools during the early ICU phase of post-CA coma.

    Suman Pradhan


    Full Text Available Seizures and neurologic involvement have been reported in patients infected with Shiga toxin (Stx producing E. coli, and hemolytic uremic syndrome (HUS with neurologic involvement is associated with more severe outcome. We investigated the extent of renal and neurologic damage in mice following injection of the highly potent form of Stx, Stx2a, and less potent Stx1. As observed in previous studies, Stx2a brought about moderate to acute tubular necrosis of proximal and distal tubules in the kidneys. Brain sections stained with hematoxylin and eosin (H&E appeared normal, although some red blood cell congestion was observed. Microglial cell responses to neural injury include up-regulation of surface-marker expression (e.g. Iba1 and stereotypical morphological changes. Mice injected with Stx2a showed increased Iba1 staining, mild morphological changes associated with microglial activation (thickening of processes, and increased microglial staining per unit area. Microglial changes were observed in the cortex, hippocampus, and amygdala regions, but not the nucleus. Magnetic resonance imaging (MRI of Stx2a-treated mice revealed no hyper-intensities in the brain, although magnetic resonance spectroscopy (MRS revealed significantly decreased levels of phosphocreatine in the thalamus. Less dramatic changes were observed following Stx1 challenge. Neither immortalized microvascular endothelial cells from the cerebral cortex of mice (bEnd.3 nor primary human brain microvascular endothelial cells were found to be susceptible to Stx1 or Stx2a. The lack of susceptibility to Stx for both cell types correlated with an absence of receptor expression. These studies indicate Stx causes subtle, but identifiable changes in the mouse brain.

  15. Shiga Toxin Mediated Neurologic Changes in Murine Model of Disease (United States)

    Pradhan, Suman; Pellino, Christine; MacMaster, Kayleigh; Coyle, Dennis; Weiss, Alison A.


    Seizures and neurologic involvement have been reported in patients infected with Shiga toxin (Stx) producing E. coli, and hemolytic uremic syndrome (HUS) with neurologic involvement is associated with more severe outcome. We investigated the extent of renal and neurologic damage in mice following injection of the highly potent form of Stx, Stx2a, and less potent Stx1. As observed in previous studies, Stx2a brought about moderate to acute tubular necrosis of proximal and distal tubules in the kidneys. Brain sections stained with hematoxylin and eosin (H&E) appeared normal, although some red blood cell congestion was observed. Microglial cell responses to neural injury include up-regulation of surface-marker expression (e.g., Iba1) and stereotypical morphological changes. Mice injected with Stx2a showed increased Iba1 staining, mild morphological changes associated with microglial activation (thickening of processes), and increased microglial staining per unit area. Microglial changes were observed in the cortex, hippocampus, and amygdala regions, but not the nucleus. Magnetic resonance imaging (MRI) of Stx2a-treated mice revealed no hyper-intensities in the brain, although magnetic resonance spectroscopy (MRS) revealed significantly decreased levels of phosphocreatine in the thalamus. Less dramatic changes were observed following Stx1 challenge. Neither immortalized microvascular endothelial cells from the cerebral cortex of mice (bEnd.3) nor primary human brain microvascular endothelial cells were found to be susceptible to Stx1 or Stx2a. The lack of susceptibility to Stx for both cell types correlated with an absence of receptor expression. These studies indicate Stx causes subtle, but identifiable changes in the mouse brain.

  16. Glutamine Synthetase: Role in Neurological Disorders. (United States)

    Jayakumar, Arumugam R; Norenberg, Michael D


    Glutamine synthetase (GS) is an ATP-dependent enzyme found in most species that synthesizes glutamine from glutamate and ammonia. In brain, GS is exclusively located in astrocytes where it serves to maintain the glutamate-glutamine cycle, as well as nitrogen metabolism. Changes in the activity of GS, as well as its gene expression, along with excitotoxicity, have been identified in a number of neurological conditions. The literature describing alterations in the activation and gene expression of GS, as well as its involvement in different neurological disorders, however, is incomplete. This review summarizes changes in GS gene expression/activity and its potential contribution to the pathogenesis of several neurological disorders, including hepatic encephalopathy, ischemia, epilepsy, Alzheimer's disease, amyotrophic lateral sclerosis, traumatic brain injury, Parkinson's disease, and astroglial neoplasms. This review also explores the possibility of targeting GS in the therapy of these conditions.

  17. Nonlocal neurology: beyond localization to holonomy. (United States)

    Globus, G G; O'Carroll, C P


    The concept of local pathology has long served neurology admirably. Relevant models include self-organizing nonlinear brain dynamics, global workspace and dynamic core theories. However such models are inconsistent with certain clinical phenomena found in Charles Bonnet syndrome, disjunctive agnosia and schizophrenia, where there is disunity of content within the unity of consciousness. This is contrasted with the split-brain case where there is disunity of content and disunity of consciousnesses. The development of quantum brain theory with it nonlocal mechanisms under the law of the whole ("holonomy") offers new possibilities for explaining disintegration within unity. Dissipative quantum brain dynamics and its approach to the binding problem, memory and consciousness are presented. A nonlocal neurology armed with a holonomic understanding might see more deeply into what clinical neurology has always aspired to: the patient as a whole.

  18. Folate deficiency and neurological disorders in adults. (United States)

    Botez, M I


    The restless legs syndrome could represent a folate responsive disorder in both patients with acquired-folate deficiency and those with familial symptomatology. Patients with acquired folate-deficiency could be divided into two subgroups. (i) those with minor neurological signs (restless legs syndrome, vibration sense impairment and tactile hypoesthesia in both legs with diminished ankle jerks and a prolonged or assymetrical Achilles-reflex time) and (ii) those with major neurological signs (subacute combined degeneration with or without neuropathies). In some of these patients the classical triad of the malabsorption syndrome is replaced by another triad, constipation, abnormal jejunal biopsy and abnormal d-xylose absorption. A low folic serum acid level could induce minor neuropsychiatric symptoms while an additional low CSF folate could induce major neurological symptoms in spite of the presence of a normal erythrocyte folate level and in the absence of frank anemia. Possible further studies are described.

  19. What is the essential neurological examination?

    Directory of Open Access Journals (Sweden)

    Marco A. Lima


    Full Text Available In order to determine which aspects would be essential to the neurological examination (NE in a given specific situation (a patient referred with a potential neurological complaint, but the history suggests that a neurological problem is unlikely, we presented the same questionnaire used by Moore and Chalk in Canada to 19 neurologists in Rio de Janeiro, Brazil. We considered significant aspects of NE, whose average responses were greater than or equal to 3.5: visual fields, fundoscopy, pursuit eye movements, facial muscle power testing, gait, pronator drift or rapid arm movement in upper limbs, finger-nose, tone in arms and legs, five tendon reflexes, and plantar responses. We concluded that, despite geographical and economical differences between Brazil and Canada, neurologists from both countries agree about the essential NE in the proposed scenario.

  20. Neurological disorders and inflammatory bowel diseases. (United States)

    Casella, Giovanni; Tontini, Gian Eugenio; Bassotti, Gabrio; Pastorelli, Luca; Villanacci, Vincenzo; Spina, Luisa; Baldini, Vittorio; Vecchi, Maurizio


    Extraintestinal manifestations occur in about one-third of patients living with inflammatory bowel disease (IBD) and may precede the onset of gastrointestinal symptoms by many years. Neurologic disorders associated with IBD are not frequent, being reported in 3% of patients, but they often represent an important cause of morbidity and a relevant diagnostic issue. In addition, the increasing use of immunosuppressant and biological therapies for IBD may also play a pivotal role in the development of neurological disorders of different type and pathogenesis. Hence, we provide a complete and profound review of the main features of neurological complications associated with IBD, with particular reference to those related to drugs and with a specific focus on their clinical presentation and possible pathophysiological mechanisms.

  1. Targeting sonic hedgehog signaling in neurological disorders. (United States)

    Patel, Sita Sharan; Tomar, Sunil; Sharma, Diksha; Mahindroo, Neeraj; Udayabanu, Malairaman


    Sonic hedgehog (Shh) signaling influences neurogenesis and neural patterning during the development of central nervous system. Dysregulation of Shh signaling in brain leads to neurological disorders like autism spectrum disorder, depression, dementia, stroke, Parkinson's diseases, Huntington's disease, locomotor deficit, epilepsy, demyelinating disease, neuropathies as well as brain tumors. The synthesis, processing and transport of Shh ligand as well as the localization of its receptors and signal transduction in the central nervous system has been carefully reviewed. Further, we summarize the regulation of small molecule modulators of Shh pathway with potential in neurological disorders. In conclusion, further studies are warranted to demonstrate the potential of positive and negative regulators of the Shh pathway in neurological disorders.

  2. The History of Reimbursements in Neurology

    Directory of Open Access Journals (Sweden)

    Shaheen E Lakhan


    Full Text Available The Patient Protection and Affordable Care Act (PPACA addresses consumer protection, employer-provided insurance coverage, as well as the government's role in providing health care access to the most vulnerable populations. Within the practice of neurology, the PPACA has the challenging goal of reconciling the needs of the growing elderly population with the financial barriers to costly yet available health care services. To bridge that gap, all health care professionals working in the field of neurology must reflect on the effect previous Medicare reimbursement policies have had on the current practice of neurology, and utilize lessons learned in recent years. The test of time will tell whether the PPACA will achieve the goal of decreasing in health care spending while ensuring quality universal healthcare services.

  3. A national neurological excellence centers network. (United States)

    Pazzi, S; Cristiani, P; Cavallini, A


    The most relevant problems related to the management of neurological disorders are (i) the frequent hospitalization in nonspecialist departments, with the need for neurological consultation, and (ii) the frequent requests of GPs for highly specialized investigations that are very expensive and of little value in arriving at a correct diagnosis. In 1996, the Consorzio di Bioingegneria e Informatica Medica in Italy realized the CISNet project (in collaboration with the Consorzio Istituti Scientifici Neuroscienze e Tecnologie Biomediche and funded by the Centro Studi of the National Public Health Council) for the implementation of a national neurological excellence centers network (CISNet). In the CISNet project, neurologists will be able to give on-line interactive consultation and off-line consulting services identifying correct diagnostic/therapeutic procedures, evaluating the need for both examination in specialist centers and admission to specialized centers, and identifying the most appropriate ones.

  4. NLRP3 deficiency ameliorates neurovascular damage in experimental ischemic stroke. (United States)

    Yang, Fan; Wang, Ziying; Wei, Xinbing; Han, Huirong; Meng, Xianfang; Zhang, Yan; Shi, Weichen; Li, Fengli; Xin, Tao; Pang, Qi; Yi, Fan


    Although the innate immune response to induce postischemic inflammation is considered as an essential step in the progression of cerebral ischemia injury, the role of innate immunity mediator NLRP3 in the pathogenesis of ischemic stroke is unknown. In this study, focal ischemia was induced by middle cerebral artery occlusion in NLRP3(-/-), NOX2(-/-), or wild-type (WT) mice. By magnetic resonance imaging (MRI), Evans blue permeability, and electron microscopic analyses, we found that NLRP3 deficiency ameliorated cerebral injury in mice after ischemic stroke by reducing infarcts and blood-brain barrier (BBB) damage. We further showed that the contribution of NLRP3 to neurovascular damage was associated with an autocrine/paracrine pattern of NLRP3-mediated interleukin-1β (IL-1β) release as evidenced by increased brain microvessel endothelial cell permeability and microglia-mediated neurotoxicity. Finally, we found that NOX2 deficiency improved outcomes after ischemic stroke by mediating NLRP3 signaling. This study for the first time shows the contribution of NLRP3 to neurovascular damage and provides direct evidence that NLRP3 as an important target molecule links NOX2-mediated oxidative stress to neurovascular damage in ischemic stroke. Pharmacological targeting of NLRP3-mediated inflammatory response at multiple levels may help design a new approach to develop therapeutic strategies for prevention of deterioration of cerebral function and for the treatment of stroke.

  5. Mechanical ventilation in neurological and neurosurgical patients. (United States)

    Swain, Amlan; Bhagat, Hemant; Sahni, Neeru; Salunke, Pravin


    Approximately 20% of all patients requiring mechanical ventilation suffer from neurological dysfunction. It is imperative in the ventilatory management of such patients to have a thorough understanding of the disease pathology that may require institution of mechanical ventilation as well as in realizing its effects on the injured brain. These patients have unique challenges pertaining to the assessment and securing of the airway, maintenance of mechanical ventilation, as well as weaning and extubation readiness. This manuscript aims to present the current evidence in ventilatory management of the important subset of patients with neuronal injury. The indications for ventilatory management include both neurological and neurosurgical causes.

  6. Stem-cell therapy for neurologic diseases

    Directory of Open Access Journals (Sweden)

    Shilpa Sharma


    Full Text Available With the advent of research on stem cell therapy for various diseases, an important need was felt in the field of neurological diseases. While congenital lesion may not be amenable to stem cell therapy completely, there is a scope of partial improvement in the lesions and halt in further progression. Neuro degenerative lesions like Parkinson′s disease, multiple sclerosis and amyotrophic lateral sclerosis have shown improvement with stem cell therapy. This article reviews the available literature and summarizes the current evidence in the various neurologic diseases amenable to stem cell therapy, the plausible mechanism of action, ethical concerns with insights into the future of stem cell therapy.

  7. Paraneoplastic Neurological Disorder in Nasopharyngeal Carcinoma (United States)

    Ng, Sze Yin; Kongg, Min Han; Yunus, Mohd Razif Mohamad


    Paraneoplastic neurological disorder (PND) is a condition due to immune cross-reactivity between the tumour cells and the normal tissue, whereby the “onconeural” antibodies attack the normal host nervous system. It can present within weeks to months before or after the diagnosis of malignancies. Nasopharyngeal carcinoma is associated with paraneoplastic syndrome, for example, dermatomyositis, and rarely with a neurological disorder. We report on a case of nasopharyngeal carcinoma with probable PND. Otolaryngologists, oncologists and neurologists need to be aware of this condition in order to make an accurate diagnosis and to provide prompt treatment. PMID:28381934

  8. Cell therapy for neurological disorders: The elusive goal

    Directory of Open Access Journals (Sweden)

    Prakash N Tandon


    Full Text Available The positive outcomes of the transplantation of fetal neural tissue in adult rat models of a variety of neurological disorders, particularly Parkinson's disease, in the 1970s, and its translation to humans in the 1980s, raised great hopes for patients suffering from these incurable disorders. This resulted in a frantic research globally to find more suitable, reliable, and ethically acceptable alternatives. The discovery of adult stem cells, embryonic stem cells, and more recently, the induced pluripotent cells further raised our expectations. The useful functional recovery in animal models using these cell transplantation techniques coupled with the desperate needs of such patients prompted many surgeons to “jump from the rat-to-man” without scientifically establishing a proof of their utility. Each new development claimed to overcome the limitations, shortcomings, safety, and other technical problems associated with the earlier technique, yet newer difficulties prevented evidence-based acceptance of their clinical use. However, thousands of patients across the globe have received these therapies without a scientifically acceptable proof of their reliability. The present review is an attempt to summarize the current status of cell therapy for neurological disorders.

  9. The interplay between microRNAs and histone deacetylases in neurological diseases. (United States)

    Bourassa, Megan W; Ratan, Rajiv R


    Neurological conditions, such as Alzheimer's disease and stroke, represent a prevalent group of devastating illnesses with few treatments. Each of these diseases or conditions is in part characterized by the dysregulation of many genes, including those that code for microRNAs (miRNAs) and histone deacetylases (HDACs). Recently, a complex relationship has been uncovered linking miRNAs and HDACs and their ability to regulate one another. This provides a new avenue for potential therapeutics as the ability to reinstate a careful balance between miRNA and HDACs has lead to improved outcomes in a number of in vitro and in vivo models of neurological conditions. In this review, we will discuss recent findings on the interplay between miRNAs and HDACs and its implications for pathogenesis and treatment of neurological conditions, including amyotrophic lateral sclerosis, Alzheimer's disease, Huntington's disease and stroke.

  10. Self-management for people with long-term neurological conditions. (United States)

    Chaplin, Hema; Hazan, Jill; Wilson, Patricia


    Although English government policy has encouraged the implementation of self-management programmes in services for people with long-term conditions, the evidence for their efficacy has been limited. People with long-term neurological conditions use community-based health services including community nursing, and have particular needs in regards to self-management. This article provides an overview of the evidence for the effectiveness of self-management interventions for people with long-term neurological conditions, in particular those with stroke, Parkinson's disease and multiple sclerosis. The current need for better interventions is highlighted, particularly the importance of providing condition-specific information and deliverance of interventions in a group setting to improve self-management outcomes. In response to weaknesses of previous self-management interventions for this population, an innovative Hertfordshire Neurological Service self-management programme is discussed, and the implications for future research are described.

  11. Development of the Neurological Institute: a strategic, improvement, and systems approach. (United States)

    Tinsley, Nancy; McCartney, Leigh Ann; Hdeib, Alia; Selman, Warren R


    The Neurological Institute at University Hospitals Case Medical Center is designed to be responsive to the ever-changing healthcare environment, aligning clinical services and goals in response to internal and external pressures for change. These goals are many, including the further development of system integration across disciplines and geographic locations, creation of a regional strategy, and research as well as education strategies that are aligned with clinical services, patient outcomes that demonstrate improved health status management, and improved financial strength. There are many details to the development of a strategic business unit such as the Neurological Institute, but this article focuses on the high-level strategies of developing the Neurological Institute and takes a closer look at the growth of one of its 16 centers of excellence.

  12. Use of Coffee Pulp and Minerals for Natural Soil Ameliorant

    Directory of Open Access Journals (Sweden)

    Pujiyanto Pujiyanto


    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.

  13. Neurologic and Cardiovascular Complications in Pediatric Life Threatening Imipramine Poisoning. (United States)

    Hon, Kam L; Fung, Ching K; Lee, Vivian W; Cheung, Kam L; Wong, William; Leung, Alexander K C


    We present an 18-month boy with imipramine poisoning to illustrate the neuro-cardiac toxic effects of this potentially deadly poison in children. The toddler ingested an unknown amount of imipramine from a non-childproof bottle which clearly labelled that the drug must be kept out of reach from children. He developed neurologic and cardiac symptoms. Electrocardiography (ECG) showed tachycardia and widened QRS. He was immediately treated with bicarbonate infusion and made an uneventful recovery. This is the youngest and only reported case of symptomatic imipramine ingestion in our locality. Imipramine has been surpassed by newer antidepressants for the treatment of depression in the past decade. Literature is searched to review the mortality rate in young children. Intensive care neuro-cardiac support contributes to the favorable outcome. Despite clear labelling of the bottle, carelessness on the part of the adult and the use of non-childproof bottle are definite preventable factor to such potentially fatal ingestion.

  14. Mentoring in neurology: filling the residency gap in academic mentoring. (United States)

    Lee, Paul R; Marsh, Elisabeth B


    Effective academic mentoring significantly affects a physician's choice of career, academic productivity, and professional trajectory. The mentoring relationship is necessary for the continued success of medical training. It is critical to cultivate a climate in which mentoring can thrive. In order to improve the quality and outcomes of mentoring, we must adopt a comprehensive plan. There are interventions at every level of training that will ensure that the current cohort of neurologists receives the requisite expertise needed to flourish and inspire future trainees. Professional organizations must articulate a comprehensive vision of mentoring. Institutions must create an infrastructure to support mentors. Mentors should work in active partnerships with their mentees to forge sustained, productive relationships. Mentees must actively contribute to their own mentoring. Proper mentorship will ensure a bright future for academic neurology.

  15. Multimodality evoked responses in the neurological assessment of the newborn. (United States)

    Mercuri, E; von Siebenthal, K; Daniëls, H; Guzzetta, F; Casaer, P


    In recent years increased attention has been devoted to evoked potentials (EP) in newborns. This paper reviews the literature and data from our research group in an attempt to assess the diagnostic and prognostic value of evoked responses in the first weeks of life and their use in different age-specific clinical conditions. The results show that EP are a very sensitive measure of the integrity of the sensory pathways. They make it possible to follow normal physiological maturation and the abnormalities of development resulting from neurological lesions. Repeated measurements of visual evoked potentials and somatosensorial evoked potential are prognostically useful in term infants, but seem much more limited in preterm newborns in predicting neurodevelopmental outcome.

    We studied contrast sensitivity function in normal subjects and in three illustrative cases with various neurological disorders. This was done by measuring contrast sensitivity over a range of spatial frequencies for vertical sinewave grating stimuli. It is demonstrated that contrast sensitivity function can give information about visual function not obtainable by conventional test procedures.

  19. Hodgkin's Lymphoma: A Review of Neurologic Complications

    Directory of Open Access Journals (Sweden)

    Sean Grimm


    Full Text Available Hodgkin's lymphoma is a hematolymphoid neoplasm, primarily of B cell lineage, that has unique histologic, immunophenotypic, and clinical features. Neurologic complications of Hodgkin's Lymphoma can be separated into those that result directly from the disease, indirectly from the disease, or from its treatment. Direct neurologic dysfunction from Hodgkin's Lymphoma results from metastatic intracranial spinal disease, epidural metastases causing spinal cord/cauda equina compression, leptomeningeal metastases, or intradural intramedullary spinal cord metastases. Indirect neurologic dysfunction may be caused by paraneoplastic disorders (such as paraneoplastic cerebellar degeneration or limbic encephalitis and primary angiitis of the central nervous system. Hodgkin's lymphoma treatment typically includes chemotherapy or radiotherapy with potential treatment-related complications affecting the nervous system. Neurologic complications resulting from mantle-field radiotherapy include the “dropped head syndrome,” acute brachial plexopathy, and transient ischemic attacks/cerebral infarcts. Chemotherapy for Hodgkin's lymphoma may cause cerebral infarction (due to emboli from anthracycline-induced cardiomyopathy and peripheral neuropathy.

  20. Need for palliative care for neurological diseases. (United States)

    Provinciali, Leandro; Carlini, Giulia; Tarquini, Daniela; Defanti, Carlo Alberto; Veronese, Simone; Pucci, Eugenio


    The new concept of palliative care supports the idea of palliation as an early approach to patients affected by disabling and life-limiting disease which focuses on the patient's quality of life along the entire course of disease. This model moves beyond the traditional concept of palliation as an approach restricted to the final stage of disease and widens the fields of intervention. There is a growing awareness of the importance of palliative care not only in oncological diseases but also in many other branches of medicine, and it appears particularly evident in the approach to many of the most frequent neurological diseases that are chronic, incurable and autonomy-impairing illnesses. The definition and implementation of palliative goals and procedures in neurology must take into account the specific features of these conditions in terms of the complexity and variability of symptoms, clinical course, disability and prognosis. The realization of an effective palliative approach to neurological diseases requires specific skills and expertise to adapt the concept of palliation to the peculiarities of these diseases; this approach should be realized through the cooperation of different services and the action of a multidisciplinary team in which the neurologist should play a central role to identify and face the patient's needs. In this view, it is paramount for the neurologist to be trained in these issues to promote the integration of palliative care in the care of neurological patients.

  6. [Education and training in neurology: update]. (United States)

    Yanagisawa, Nobuo


    Progress in basic neurosciences and advances in technology in the last decades have contributed to clarification of neural mechanisms in behavior or cognition in health and disease. They have elaborated diagnosis and treatment of nervous diseases remarkably. Needs in neurologists in both primary and specific medical services are rapidly increasing, with aging society and progresses in medical care in Japan. Attraction of neurology for students and junior residents is a great concern of Japanese Society of Neurology. In the undergraduate education, recent achievement in basic neurosciences including neurogenetics, molecular cytology, physio-pathology and imaging technique should be taught comprehensively. In the early postgraduate course for two years, neurology is either elective or obligatory depending on the curriculum of training institutions. Work at the stroke care unit is strongly recommended in the course of emergency service, which is mandatory. Experiences in acute infectious diseases, in various stages of neurodegenerative diseases, in collaboration with other specialist doctors for systemic diseases including metabolic or collagen diseases, in collaboration with other medical personnel in care of dementia are all included in advanced stages of postgraduate education before board examination. In summary, studies for practical services as well as clinical researches, teaching of symptoms and signs based on neural functions, and socio-economical issues for chronic nervous diseases in aged society are important in the education in neurology.

  7. Pediatric hydrocephalus outcomes: a review

    Directory of Open Access Journals (Sweden)

    Vinchon Matthieu


    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.

  8. Ameliorated GA approach for base station planning (United States)

    Wang, Andong; Sun, Hongyue; Wu, Xiaomin


    In this paper, we aim at locating base station (BS) rationally to satisfy the most customs by using the least BSs. An ameliorated GA is proposed to search for the optimum solution. In the algorithm, we mesh the area to be planned according to least overlap length derived from coverage radius, bring into isometric grid encoding method to represent BS distribution as well as its number and develop select, crossover and mutation operators to serve our unique necessity. We also construct our comprehensive object function after synthesizing coverage ratio, overlap ratio, population and geographical conditions. Finally, after importing an electronic map of the area to be planned, a recommended strategy draft would be exported correspondingly. We eventually import HongKong, China to simulate and yield a satisfactory solution.

  9. Dermatology referrals in a neurological set up

    Directory of Open Access Journals (Sweden)

    Deeptara Pathak Thapa


    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

  10. Telemedicine in emergency neurological service provision in Singapore: using technology to overcome limitations. (United States)

    Singh, Rajinder; Ng, Wai Hoe; Lee, Kim En; Wang, Ernest; Ng, Ivan; Lee, Wei Ling


    Medical emergencies form a significant proportion of neurological and neurosurgical practice. The highly specialized nature of neurology and neurosurgery limits expertise to a small number of highly specialized centers; hence, many neurological emergencies will be managed in regional hospitals without comprehensive support. The common theme in neurological emergencies lies with prompt diagnosis, rapid access to scans, accurate scan interpretation, and quick institution of appropriate treatment. Failure in any one of these can result in devastating and permanent neurological deficits or death. The judicious use of information and communication technology can overcome some of the limitations imposed by scarce resources. Multimedia messaging service can be used to transmit important scan images to experienced staff to faciliate accurate and prompt diagnosis and commence optimal treatment. Telestroke based on the remote evaluation of acute ishemic stroke model can also be utilized so that selected stroke patients can be given intravenous tissue plasminogen activator in the emergency department of a regional hospital with the supervision of a stroke neurologist. We describe our experience with these technological initiatives to improve clinical care and outcome in our patients.

  11. Child neurology: Past, present, and future: part 1: history. (United States)

    Millichap, John J; Millichap, J Gordon


    The founding period of child neurology occurred in 3 phases: 1) early individual contributory phase, 2) organized training phase, and 3) expansion phase. In the late 19th and early 20th centuries, individuals in pediatrics, neurology, and psychiatry established clinics and made important contributions to the literature on childhood epilepsy, cerebral palsy, and pediatric neurology. The latter half of the 20th century saw the organization of training programs in pediatric neurology, with fellowships supported by the NIH. This development was followed by a rapid expansion in the number of trainees certified in child neurology and their appointment to divisions of neurology in children's hospitals. In recent years, referrals of children with neurologic disorders have increased, and disorders previously managed by pediatricians are often seen in neurology clinics. The era of subspecialization is embraced by the practicing physician. The present day status of pediatric neurology and suggestions for the future development of the specialty are subjects for further discussion.

  12. Helicobacter pylori and neurological diseases: Married by the laws of inflammation. (United States)

    Alvarez-Arellano, Lourdes; Maldonado-Bernal, Carmen


    The purpose of this paper is to review current information about the role of inflammation caused by Helicobacter pylori (H. pylori) infection in neurological diseases such as Parkinson's disease, Alzheimer's disease, 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 including chemokines [interleukin (IL)-8, macrophage chemotactic protein (MCP)-1, growth-regulated oncogene (GRO)-α] and cytokines [IL-1β, tumor necrosis factor (TNF)-α, IL-6, IL-12, interferon (IFN)-γ], which can pass into the circulation and have a systemic effect. The persistence of detectable systemic and local 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 associated 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 combination of multiple factors, but the systemic inflammatory response is a common component and determinant in the onset, evolution, and outcome of diseases. However, more studies are needed to allow understanding of the effects and mechanisms by which the inflammatory response generated by H. pylori infection affects neurological diseases.

  13. Contemporary Teaching of Neurology. Teaching Neurological Behavior to General Practitioners: A Fresh Approach (United States)

    Derouesne, C.; Salamon, R.


    Ways in which teaching neurology can be simplified for the nonspecialist practitioner are addressed in this assessment of the state-of-the-art in France. The hypothesis implies simplifying both the diagnoses and symptomatology. (LBH)

  14. [Nutritional and metabolic aspects of neurological diseases]. (United States)

    Planas Vilà, Mercè


    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. The periodic nutritional

  15. Neurology as career option among postgraduate medical students

    Directory of Open Access Journals (Sweden)

    Namit B Gupta


    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

  16. Risk factors for early post-operative neurological deterioration in dogs undergoing a cervical dorsal laminectomy or hemilaminectomy: 100 cases (2002-2014). (United States)

    Taylor-Brown, F E; Cardy, T J A; Liebel, F X; Garosi, L; Kenny, P J; Volk, H A; De Decker, S


    Early post-operative neurological deterioration is a well-known complication following dorsal cervical laminectomies and hemilaminectomies in dogs. This study aimed to evaluate potential risk factors for early post-operative neurological deterioration following these surgical procedures. Medical records of 100 dogs that had undergone a cervical dorsal laminectomy or hemilaminectomy between 2002 and 2014 were assessed retrospectively. Assessed variables included signalment, bodyweight, duration of clinical signs, neurological status before surgery, diagnosis, surgical site, type and extent of surgery and duration of procedure. Outcome measures were neurological status immediately following surgery and duration of hospitalisation. Univariate statistical analysis was performed to identify variables to be included in a multivariate model. Diagnoses included osseous associated cervical spondylomyelopathy (OACSM; n = 41), acute intervertebral disk extrusion (IVDE; 31), meningioma (11), spinal arachnoid diverticulum (10) and vertebral arch anomalies (7). Overall 54% (95% CI 45.25-64.75) of dogs were neurologically worse 48 h post-operatively. Multivariate statistical analysis identified four factors significantly related to early post-operative neurological outcome. Diagnoses of OACSM or meningioma were considered the strongest variables to predict early post-operative neurological deterioration, followed by higher (more severely affected) neurological grade before surgery and longer surgery time. This information can aid in the management of expectations of clinical staff and owners with dogs undergoing these surgical procedures.

  17. Psychiatry and neurology: from dualism to integration. (United States)

    Sobański, Jerzy A; Dudek, Dominika


    The two objectives of the following paper are: to make few remarks on the topic absorbing neurologists, psychiatrists, and neuropsychiatrists - integration and division of their specialties; and to describe the situation in Poland, reflected in the latest literature. The authors describe the former and present processes of approaches and divisions in psychiatry and neurology. They indicate dissemination of mutual methods of structural and action brain neuroimaging, neurophysiology, neurogenetics, and advanced neurophysiology diagnostics. As it seems, even the effectiveness of psychotherapy, has recently been associated with changes in brain in functional and even structural markers. The authors indicate the value of the strive to join the still divided specialties, reflected worldwide in attempts of common education and clinical cooperation of physicians. It can be expected that subsequent years will bring further triumphs of neuropsychiatry - a field that combines psychiatry and neurology.

  18. Positive clinical neuroscience: explorations in positive neurology. (United States)

    Kapur, Narinder; Cole, Jonathan; Manly, Tom; Viskontas, Indre; Ninteman, Aafke; Hasher, Lynn; Pascual-Leone, Alvaro


    Disorders of the brain and its sensory organs have traditionally been associated with deficits in movement, perception, cognition, emotion, and behavior. It is increasingly evident, however, that positive phenomena may also occur in such conditions, with implications for the individual, science, medicine, and for society. This article provides a selective review of such positive phenomena--enhanced function after brain lesions, better-than-normal performance in people with sensory loss, creativity associated with neurological disease, and enhanced performance associated with aging. We propose that, akin to the well-established field of positive psychology and the emerging field of positive clinical psychology, the nascent fields of positive neurology and positive neuropsychology offer new avenues to understand brain-behavior relationships, with both theoretical and therapeutic implications.

  19. Neurological manifestations of Chikungunya and Zika infections

    Directory of Open Access Journals (Sweden)

    Talys J. Pinheiro

    Full Text Available ABSTRACT The epidemics of Chikungunya virus (CHIKV and Zika virus (ZIKV infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others. The diagnosis is based on clinical, epidemiological, and laboratory criteria. The most common symptoms of ZIKV infection are skin rash (mostly maculopapular, fever, arthralgia, myalgia, headache, and conjunctivitis. Some epidemics that have recently occurred in French Polynesia and Brazil, reported the most severe conditions, with involvement of the nervous system (Guillain-Barré syndrome, transverse myelitis, microcephaly and meningitis. The treatment for ZIKV and CHIKV infections are symptomatic and the management for neurological complications depends on the type of affliction. Intravenous immunoglobulin, plasmapheresis, and corticosteroid pulse therapy are options.

  20. Neurological abnormalities associated with CDMA exposure. (United States)

    Hocking, B; Westerman, R


    Dysaesthesiae of the scalp and neurological abnormality after mobile phone use have been reported previously, but the roles of the phone per se or the radiations in causing these findings have been questioned. We report finding a neurological abnormality in a patient after accidental exposure of the left side of the face to mobile phone radiation [code division multiple access (CDMA)] from a down-powered mobile phone base station antenna. He had headaches, unilateral left blurred vision and pupil constriction, unilateral altered sensation on the forehead, and abnormalities of current perception thresholds on testing the left trigeminal ophthalmic nerve. His nerve function recovered during 6 months follow-up. His exposure was 0.015-0.06 mW/cm(2) over 1-2 h. The implications regarding health effects of radiofrequency radiation are discussed.

  1. The neurology of aretaeus: radix pedis neurologia. (United States)

    Pearce, J M S


    Aretaeus (Aretaios) was a physician born in Cappadocia in about the 2nd century AD, a student of medicine and physician in Alexandria. His works are found in eight books which espoused the physiological and pathological views of the Hippocratic principles derived from the pneumatists and the eclectic schools. Though he has been called the forgotten physician, it has been said that: 'after Hippocrates no single Greek author has equalled Aretaios'. In order to give an indication of his neurological legacy, this paper offers a summary of and quotations from his principal neurological contributions: migraine, vertigo, tetanus, epilepsy, melancholia, strokes and paralysis. One of his most important discoveries was the notion that the pyramidal tract decussates.

  2. Complex I deficiencies in neurological disorders. (United States)

    Papa, Sergio; De Rasmo, Domenico


    Complex I is the point of entry in the mitochondrial electron transport chain for NADH reducing equivalents, and it behaves as a regulatable pacemaker of respiratory ATP production in human cells. Defects in complex I are associated with several human neurological disorders, including primary mitochondrial diseases, Parkinson disease (PD), and Down syndrome, and understanding the activity and regulation of complex I may reveal aspects of the underlying pathogenic mechanisms. Complex I is regulated by cyclic AMP (cAMP) and the protein kinase A (PKA) signal transduction pathway, and elucidating the role of the cAMP/PKA system in regulating complex I and oxygen free radical production provides new perspectives for devising therapeutic strategies for neurological diseases.

  3. Neuroelectrophysiological studies on neurological autoimmune diseases

    Directory of Open Access Journals (Sweden)

    Yin-hong LIU


    Full Text Available The neuroelectrophysiological manifestations of four clinical typical neurological autoimmune diseases including multiple sclerosis (MS, Guillain-Barré syndrome (GBS, myasthenia gravis (MG, and polymyositis and dermatomyositis were reviewed in this paper. The diagnostic value of evoked potentials for multiple sclerosis, nerve conduction studies (NCS for Guillain-Barré syndrome, repetitive nerve stimulation (RNS and single-fiber electromyography (SFEMG for myasthenia gravis, and needle electromyography for polymyositis and dermatomyositis were respectively discussed. This review will help to have comprehensive understanding on electrophysiological examinations and their clinical significance in the diagnosis of neurological autoimmune diseases. doi: 10.3969/j.issn.1672-6731.2014.09.004

  4. [Neurological complications of inflammatory bowel disease]. (United States)

    Bermejo, Pedro Emilio; Burgos, Aurora


    Although ulcerative colitis and Crohn's disease have traditionally been considered to be inflammatory diseases limited to the gastrointestinal tract, it has been shown that both pathologies are frequently accompanied by various extraintestinal disorders. There is an increasing evidence that they may also manifest in the nervous system, including the peripheral and the central parts. Although some of these neurological complications have been known for a long time, such as cerebrovascular disease, vasculitis and autoinmune processes including neuropathies and cerebral demyelination, others have been recently described. With the exception of some of this complications such as the thromboembolism, evidence for a casual relationship relies merely on single case reports or case series. In this article, we try to review the existing evidence on neurological manifestations of both variants of inflammatory bowel disease.

  5. Epigenetic mechanisms in neurological and neurodegenerative diseases.

    Directory of Open Access Journals (Sweden)

    Jorge eLandgrave-Gómez


    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

  6. Chapter 40: history of neurology in France. (United States)

    Clarac, François; Boller, François


    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

    Ivana I Berisavac; Pavlović, Aleksandra M.; Jasna J. Zidverc Trajković; Čovičković Šternić, Nadežda M; Ljiljana G. Beslać Bumbaširević


    Vertigo is a common symptom in everyday clinical practice. The treatment depends on the specific etiology. Vertigo may be secondary to inner ear pathology, or any existing brainstem or cerebellar lesion but may also be psychogenic. Central vertigo is a consequence of a central nervous system lesion. It is often associated with a focal neurological deficit. Peripheral vertigo is secondary to dysfunction of the peripheral vestibular system and is usually characterized by an acute vertigo with l...

  8. Microvesicles: novel biomarkers for neurological disorders

    Directory of Open Access Journals (Sweden)

    Bruno eBorgiani


    Full Text Available Microvesicles (MVs are released by most cell types in physiological conditions, but their number is often increased upon cellular activation or neoplastic transformation. This suggests that their detection may be helpful in pathological conditions to have information on activated cell types and, possibly, on the nature of the activation. This could be of importance in districts and tissues that are not accessible to direct examination, such as the central nervous system (CNS. Increased release of MVs has been described to be associated to the acute or active phase of several neurological disorders. While the subcellular origin of MVs (exosome or ectosomes is never addressed in these studies because of technical limitations, the cell of origin is always identified. Endothelium- or platelet-derived MVs, detected in plasma or serum, are linked to neurological pathologies with a vascular or ischemic pathogenic component, and may represent a very useful marker to support therapeutic choices in stroke. In neuroinflammatory disorders, such as multiple sclerosis (MS, MVs of oligodendroglial or microglial origin have been described in the CSF and may carry, in perspective, additional information on the biological alterations in their cell of origin. Little specific evidence is available in neurodegenerative disorders and, specifically, MVs of neural origin have never been investigated in these pathologies. Few data have been reported for neuroinfection and brain trauma. In brain tumors, despite the limited number of studies performed, results are very promising and potentially close to clinical translation. We here review all currently available data on the detection of MVs in neurological diseases, limiting our search to exclusively human studies. Current literature and our own data indicate that MVs detection may represent a very promising strategy to gain pathogenic information, identify therapeutic targets, and select specific biomarkers for

    The motor relearning program can significantly improve various functional disturbance induced by ischemic cerebrovascular diseases. However, its mechanism of action remains poorly understood. In injured brain tissues, glial fibrillary acidic protein and neurofilament protein changes can reflect the condition of injured neurons and astrocytes, while vascular endothelial growth factor and basic fibroblast growth factor changes can indicate angiogenesis. In the present study, we induced ischemic brain injury in the rhesus macaque by electrocoagulation of the M1 segment of the right middle cerebral artery. The motor relearning program was conducted for 60 days from the third day after model establishment. Immunohistochemistry and single-photon emission CT showed that the numbers of glial fibrillary acidic protein-, neurofilament protein-, vascular endothelial growth factorand basic fibroblast growth factor-positive cells were significantly increased in the infarcted side compared with the contralateral hemisphere following the motor relearning program. Moreover, cerebral blood flow in the infarcted side was significantly improved. The clinical rating scale for stroke was used to assess neurological function changes in the rhesus macaque following the motor relearning program. Results showed that motor function was improved, and problems with consciousness, self-care ability and balance function were significantly ameliorated. These findings indicate that the motor relearning program significantly promoted neuronal regeneration, repair and angiogenesis in the surroundings of the infarcted hemisphere, and improve neurological function in the rhesus macaque following brain ischemia.

  11. Remote care of a patient with stroke in rural Trinidad: use of telemedicine to optimise global neurological care. (United States)

    Reyes, Antonio Jose; Ramcharan, Kanterpersad


    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.

  14. Nanotechnology based diagnostics for neurological disorders

    Energy Technology Data Exchange (ETDEWEB)

    Kurek, Nicholas S.; Chandra, Sathees B., E-mail: [Department of Biological, Chemical and Physical Sciences, Roosevelt University, Chicago, IL (United States)


    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)

  15. NIRS in clinical neurology - a 'promising' tool? (United States)

    Obrig, Hellmuth


    Near-infrared spectroscopy (NIRS) has become a relevant research tool in neuroscience. In special populations such as infants and for special tasks such as walking, NIRS has asserted itself as a low resolution functional imaging technique which profits from its ease of application, portability and the option to co-register other neurophysiological and behavioral data in a 'near natural' environment. For clinical use in neurology this translates into the option to provide a bed-side oximeter for the brain, broadly available at comparatively low costs. However, while some potential for routine brain monitoring during cardiac and vascular surgery and in neonatology has been established, NIRS is largely unknown to clinical neurologists. The article discusses some of the reasons for this lack of use in clinical neurology. Research using NIRS in three major neurologic diseases (cerebrovascular disease, epilepsy and headache) is reviewed. Additionally the potential to exploit the established position of NIRS as a functional imaging tool with regard to clinical questions such as preoperative functional assessment and neurorehabilitation is discussed.

  16. Gene Editing for Treatment of Neurological Infections. (United States)

    White, Martyn K; Kaminski, Rafal; Wollebo, Hassen; Hu, Wenhui; Malcolm, Thomas; Khalili, Kamel


    The study of neurological infections by viruses defines the field of neurovirology, which has emerged in the last 30 years and was founded upon the discovery of a number of viruses capable of infecting the human nervous system. Studies have focused on the molecular and biological basis of viral neurological diseases with the aim of revealing new therapeutic options. The first studies of neurovirological infections can be traced back to the discovery that some viruses have an affinity for the nervous system with research into rabies by Louis Pasteur and others in the 1880s. Today, the immense public health impact of neurovirological infections is illustrated by diseases such as neuroAIDS, progressive multifocal leukoencephalopathy, and viral encephalitis. Recent research has seen the development of powerful new techniques for gene editing that promise revolutionary opportunities for the development of novel therapeutic options. In particular, clustered regulatory interspaced short palindromic repeat-associated 9 system provides an effective, highly specific and versatile tool for targeting DNA viruses that are beginning to allow the development of such new approaches. In this short review, we discuss these recent developments, how they pertain to neurological infections, and future prospects.

    León-Sarmiento, Fidias E; Prada, Diddier G; Bayona-Prieto, Jaime; Valderrama, Vladimir; García, Ingrid; León, Marta E; Sunnemark, Dan


    Trypanosoma cruzi, causative agent of Chagas disease, affects not only cardiac and intestinal structures but also neurological structures. A high prevalence of T. cruzi infection occurs in Colombia, prompting the present study. First, a qualitative metaanalysis was undertaken using the PubMed database, the electronic internet engine Altavista, Colombian journals indexed by Colciencias, and three relevant textbooks. The following key words were used: Trypanosoma, Chagas disease, nervous system, spinal cord, central nervous system, peripheral nervous system, neuromuscular junction, autonomic nervous system, muscle, muscle disorders, neuromuscular disease, neuromuscular disorders, synapticopathies and dysautonomia. The documents analyzed numbered 116 and included original papers, reviews, case reports, editorials, brief communications, conferences and book chapters. At minimum, each document included data involving ELISA testing, indirect immunofluorescense, or parasitemia levels in the clinical, serological or histopathological studies. Polymerase chain reaction (PCR) studies were not included because of the recent introduction of PCR as a confirmatory technique for Chagas disease in Colombia. Chagas disease affects the central, the peripheral and the autonomic nervous system in humans, although its effects on the antonomic system is most commonly investigated in Colombia. Neurological lesions must be evaluated carefully, because patients may be misdiagnosed and treated as carriers of 'idiopathic' diseases. Neurological pathologies poses a serious threat in Colombia due to the prevalence of Chagas disease.

    Pekny, Milos; Pekna, Marcela; Messing, Albee; Steinhäuser, Christian; Lee, Jin-Moo; Parpura, Vladimir; Hol, Elly M; Sofroniew, Michael V; Verkhratsky, Alexei


    The neurone-centred view of the past disregarded or downplayed the role of astroglia as a primary component in the pathogenesis of neurological diseases. As this concept is changing, so is also the perceived role of astrocytes in the healthy and diseased brain and spinal cord. We have started to unravel the different signalling mechanisms that trigger specific molecular, morphological and functional changes in reactive astrocytes that are critical for repairing tissue and maintaining function in CNS pathologies, such as neurotrauma, stroke, or neurodegenerative diseases. An increasing body of evidence shows that the effects of astrogliosis on the neural tissue and its functions are not uniform or stereotypic, but vary in a context-specific manner from astrogliosis being an adaptive beneficial response under some circumstances to a maladaptive and deleterious process in another context. There is a growing support for the concept of astrocytopathies in which the disruption of normal astrocyte functions, astrodegeneration or dysfunctional/maladaptive astrogliosis are the primary cause or the main factor in neurological dysfunction and disease. This review describes the multiple roles of astrocytes in the healthy CNS, discusses the diversity of astroglial responses in neurological disorders and argues that targeting astrocytes may represent an effective therapeutic strategy for Alexander disease, neurotrauma, stroke, epilepsy and Alzheimer's disease as well as other neurodegenerative diseases.

  19. Clinical neurological examination of infants and children. (United States)

    Haslam, Robert H A


    A thorough but focused history and neurological examination remain the most important initial elements of neurological diagnosis at all ages. Advances over the past two decades in clinical neurophysiology, neuroimaging, genetics, and neuropathological examination of tissue have at times appeared to predominate over traditional history and physical exam, but no laboratory studies can provide the focus and clues to diagnosis that clinical findings offer. History taking and the techniques of neurological examination are skills to be learned by the student, refined by the resident, and practiced and perfected throughout the career of a pediatric neurologist. Examination must be specifically modified to correspond to age and with the expectation of developmental skills achieved at various ages, in addition to the localizing value of particular signs that may apply at all ages. Hypotonia, extensor plantar responses, and lack of visual fixation may be normal in a preterm infant but abnormal at several months of age. "Primitive" reflexes disappear at a certain age, but really are only suppressed or inhibited and may become re-expressed with disinhibition many decades later. Finally, the pediatric neurologist needs to have a firm foundation in normal development, neuroembryology, and changes in the expression of diseases at various stages of maturation of the nervous system.

  20. Neurologic complications of valvular heart disease. (United States)

    Cruz-Flores, Salvador


    Valvular heart disease (VHD) is frequently associated with neurologic complications; cerebral embolism is the most common of these since thrombus formation results from the abnormalities in the valvular surfaces or from the anatomic and physiologic changes associated with valve dysfunction, such as atrial or ventricular enlargement, intracardiac thrombi, and cardiac dysrhythmias. Prosthetic heart valves, particularly mechanical valves, are very thrombogenic, which explains the high risk of thromboembolism and the need for anticoagulation for the prevention of embolism. Infective endocarditis is a disease process with protean manifestations that include not only cerebral embolism but also intracranial hemorrhage, mycotic aneurysms, and systemic manifestations such as fever and encephalopathy. Other neurologic complications include nonbacterial thrombotic endocarditis, a process associated with systemic diseases such as cancer and systemic lupus erythematosus. For many of these conditions, anticoagulation is the mainstay of treatment to prevent cerebral embolism, therefore it is the potential complications of anticoagulation that can explain other neurologic complications in patients with VHD. The prevention and management of these complications requires an understanding of their natural history in order to balance the risks posed by valvular disease itself against the risks and benefits associated with treatment.

  1. Human neurologic function and the aging process. (United States)

    Potvin, A R; Syndulko, K; Tourtellotte, W W; Lemmon, J A; Potvin, J H


    Sixty-one normal men whose ages ranged from 20 to 80 years were evaluated on two occasions by means of a comprehensive series of 128 instrumented tests of neurologic function. The tests measured cognition, vision, strength, steadiness, reactions, speed, coordination, fatigue, gait, station, sensations, and tasks of daily living. The reliability of each test measured was determined, and any measure found unreliable (r less than or equal to 0.41) was not further analyzed. Significant age-related linear decreases were found for almost all neurologic functions. The declines over the age span varied from less than 10 percent to more than 90 percent for different functions. For the upper extremities, the largest declines (greater than 50 percent) were in hand-force steadiness, speed of hand-arm movements, and vibration sense; for the lower extremities, the largest declines were in one-legged balance with eyes closed and in vibration sense. For 13 of 14 tests in which significant dominant body-side effects were found, larger re-testing 7-10 days later, the subjects improved their scores by more than 5 percent on only 17 tests, 9 of which concerned the activities of daily living. No significant differential learning effects were found across age groups. The results point to the importance of developing a data bank on age-based neurologic function so that therapeutic effects can be evaluated in terms of age- and sex-matched normal functioning.

  2. Neurology in the United Kingdom. I: Historical development.


    Langton Hewer, R; Wood, V A


    International comparisons suggest that British neurological services are underdeveloped. Historical factors which have contributed to the current state of neurological services in the United Kingdom are described. Key issues include the dominance of London and the concept of specialised hospitals in the early history of neurology; the subsequent recognition of the needs of other parts of the United Kingdom, of district general hospitals, and of patients with chronic neurological disabilities ...

    Neurologic complications have long been associated with influenza. A novel strain of influenza A (H1N1) first described in humans to have outbreak potential in 2009 in Mexico went on to become the first influenza pandemic of this century. We evaluated the neurologic complications of the novel influenza A (H1N1) 2009 in children and adults admitted to all public hospitals in Singapore during the influenza A (H1N1) 2009 pandemic between May 2009 and March 2010. All patients were positive for novel H1N1 infection and presented with neurologic symptoms prior to oseltamivir treatment. Ninety-eight patients (median age 6.6 years, range 0.4-62.6) were identified; 90 % were younger than 18 years; 32 % suffered from preexisting neurological, respiratory, or cardiac disease; and 66 % presented with seizures. Of those presenting with seizures, new onset seizures were the most common manifestation (n = 40, 61.5 %), followed by breakthrough seizures (n = 18, 27.7 %) and status epilepticus (n = 7, 10.8 %). Influenza-associated encephalopathy occurred in 20 %. The majority of children (n = 88) presented with seizures (n = 63, 71.6 %), encephalopathy (n = 19, 21.6 %), and syncope (n = 4, 4.5 %). Among adults, a wider range of neurological conditions were seen, with half of them presenting with an exacerbation of their underlying neurological disease. The neurological symptoms developed at a median of 2 days after the onset of systemic symptoms. The median length of hospital stay was 3 days, and 79 % were monitored in general wards. Neurologic complications associated with the novel influenza A (H1N1) 2009 strain were generally mild and had a good outcome. They occurred more frequently in patients with underlying neurological disorders. Seizures and encephalopathy were the most common manifestations, similar to other influenza virus strains.

  6. Aedes aegypti salivary gland extract ameliorates experimental inflammatory bowel disease. (United States)

    Sales-Campos, Helioswilton; de Souza, Patricia Reis; Basso, Paulo José; Ramos, Anderson Daniel; Nardini, Viviani; Chica, Javier Emílio Lazo; Capurro, Margareth Lara; Sá-Nunes, Anderson; de Barros Cardoso, Cristina Ribeiro


    Current therapies for inflammatory bowel disease (IBD) are not totally effective, resulting in persistent and recurrent disease for many patients. Mosquito saliva contains immunomodulatory molecules and therein could represent a novel therapy for IBD. Here, we demonstrated the therapeutic activity of salivary gland extract (SGE) of Aedes aegypti on dextran sulfate sodium (DSS)-induced colitis. For this purpose, C57BL/6 male mice were exposed to 3% DSS in drinking water and treated with SGE at early (days 3-5) or late (days 5-8) time points, followed by euthanasia on days 6 and 9, respectively, for sample collection. The results showed an improvement in clinical disease outcome and postmortem scores after SGE treatment, accompanied by the systemic reduction in peripheral blood lymphocytes, with no impact on bone marrow and mesenteric lymph nodes cellularity or macrophages toxicity. Moreover, a local diminishment of IFN-γ, TNF-α, IL-1β and IL-5 cytokines together with a reduction in the inflammatory area were observed in the colon of SGE-treated mice. Strikingly, early treatment with SGE led to mice protection from a late DSS re-challenging, as observed by decreased clinical and postmortem scores, besides reduced circulating lymphocytes, indicating that the mosquito saliva may present components able to prevent disease relapse. Indeed, high performance liquid chromatography (HPLC) experiments pointed to a major SGE pool fraction (F3) able to ameliorate disease signs. In conclusion, SGE and its components might represent a source of important immunomodulatory molecules with promising therapeutic activity for IBD.

    Sanjeev Rastogi


    Full Text Available Spinal cord injury (SCI is associated with worst outcomes and requires a prolonged rehabilitation. Ayurvedic indigenous methods of rehabilitation are often utilized to treat such conditions. A case of SCI was followed up for 3 months upon an Ayurvedic composite intervention and subsequently reported. The composite treatment plan involved Ayurvedic oral medications as well as a few selected external and internal pancha karma procedures. A substantial clinical and patient centered outcome improvement in existing neurological deficits and quality of life was observed after 3 months of the Ayurvedic treatment given to this case.

  9. Neuromarketing and consumer neuroscience: contributions to neurology (United States)


    Background ‘Neuromarketing’ is a term that has often been used in the media in recent years. These public discussions have generally centered around potential ethical aspects and the public fear of negative consequences for society in general, and consumers in particular. However, positive contributions to the scientific discourse from developing a biological model that tries to explain context-situated human behavior such as consumption have often been neglected. We argue for a differentiated terminology, naming commercial applications of neuroscientific methods ‘neuromarketing’ and scientific ones ‘consumer neuroscience’. While marketing scholars have eagerly integrated neuroscientific evidence into their theoretical framework, neurology has only recently started to draw its attention to the results of consumer neuroscience. Discussion In this paper we address key research topics of consumer neuroscience that we think are of interest for neurologists; namely the reward system, trust and ethical issues. We argue that there are overlapping research topics in neurology and consumer neuroscience where both sides can profit from collaboration. Further, neurologists joining the public discussion of ethical issues surrounding neuromarketing and consumer neuroscience could contribute standards and experience gained in clinical research. Summary We identify the following areas where consumer neuroscience could contribute to the field of neurology: First, studies using game paradigms could help to gain further insights into the underlying pathophysiology of pathological gambling in Parkinson’s disease, frontotemporal dementia, epilepsy, and Huntington’s disease. Second, we identify compulsive buying as a common interest in neurology and consumer neuroscience. Paradigms commonly used in consumer neuroscience could be applied to patients suffering from Parkinson’s disease and frontotemporal dementia to advance knowledge of this important behavioral symptom

  10. Wnt7a treatment ameliorates muscular dystrophy. (United States)

    von Maltzahn, Julia; Renaud, Jean-Marc; Parise, Gianni; Rudnicki, Michael A


    Duchenne muscular dystrophy (DMD) is a devastating genetic muscular disorder of childhood marked by progressive debilitating muscle weakness and wasting, and ultimately death in the second or third decade of life. Wnt7a signaling through its receptor Fzd7 accelerates and augments regeneration by stimulating satellite stem cell expansion through the planar cell polarity pathway, as well as myofiber hypertrophy through the AKT/mammalian target of rapamycin (mTOR) anabolic pathway. We investigated the therapeutic potential of the secreted factor Wnt7a for focal treatment of dystrophic DMD muscles using the mdx mouse model, and found that Wnt7a treatment efficiently induced satellite cell expansion and myofiber hypertrophy in treated mucles in mdx mice. Importantly, Wnt7a treatment resulted in a significant increase in muscle strength, as determined by generation of specific force. Furthermore, Wnt7a reduced the level of contractile damage, likely by inducing a shift in fiber type toward slow-twitch. Finally, we found that Wnt7a similarly induced myotube hypertrophy and a shift in fiber type toward slow-twitch in human primary myotubes. Taken together, our findings suggest that Wnt7a is a promising candidate for development as an ameliorative treatment for DMD.

  11. Amelioration of safety management in infrastructure projects

    Directory of Open Access Journals (Sweden)

    Mr. Gopinath S.Mohite


    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.

  12. Resveratrol Pretreatment Ameliorates TNBS Colitis in Rats. (United States)

    Yildiz, Gulserap; Yildiz, Yuksel; Ulutas, Pinar A; Yaylali, Asl; Ural, Muruvvet


    Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory disease in humans constituting a major health concern today whose prevalence has been increasing over the world. Production of reactive oxygen species (ROS) and disturbed capacity of antioxidant defense in IBD subjects have been reported. Antioxidants may play a significant role in IBD treatment. This study aimed at evaluating ameliorative effects of intraperitoneal resveratrol pretreatment on trinitrobenzene sulphonic acid (TNBS)-induced colitis in rats. Thirty five Wistar-Albino female rats were divided equally into five groups. Inflammation was induced by the intrarectal administration of TNBS under anesthesia. Intraperitoneal administration of resveratrol (RSV) at a concentration of 10mg/kg/day for 5 days before the induction of colitis significantly reduced microscopy score and malondialdehyde (MDA) levels and increased glutathione peroxidase (GSH Px) activity compared to TNBS and vehicle groups. Also an insignificant increase in catalase (CAT) activity was observed in the RSV treated group compared to TNBS and vehicle groups. In this paper, the most recent patent on the identification and treatment of IBD was indicated. In conclusion, antioxidant RSV proved to have a beneficial effect on TNBS colitis in rats. In light of these advantageous results, the RSV can be considered as adjuvant agent in IBD treatments.

    Finnie, J W; Windsor, P A; Kessell, A E


    Disease surveillance is an integral part of most veterinary practices in Australia. The aim of this series of invited reviews is to facilitate the differential and ultimately definitive diagnosis of some of the previously known, as well as the novel and emerging, neurological disorders of ruminant livestock, which is of particular importance in the surveillance for transmissible spongiform encephalopathies. General principles of a systematic neurological examination, necropsy procedures and the neurological manifestations of systemic disease, trauma and neoplasia are described here.

  16. Bridging neuroanatomy, neuroradiology and neurology: three-dimensional interactive atlas of neurological disorders. (United States)

    Nowinski, W L; Chua, B C


    Understanding brain pathology along with the underlying neuroanatomy and the resulting neurological deficits is of vital importance in medical education and clinical practice. To facilitate and expedite this understanding, we created a three-dimensional (3D) interactive atlas of neurological disorders providing the correspondence between a brain lesion and the resulting disorder(s). The atlas contains a 3D highly parcellated atlas of normal neuroanatomy along with a brain pathology database. Normal neuroanatomy is divided into about 2,300 components, including the cerebrum, cerebellum, brainstem, spinal cord, arteries, veins, dural sinuses, tracts, cranial nerves (CN), white matter, deep gray nuclei, ventricles, visual system, muscles, glands and cervical vertebrae (C1-C5). The brain pathology database contains 144 focal and distributed synthesized lesions (70 vascular, 36 CN-related, and 38 regional anatomy-related), each lesion labeled with the resulting disorder and associated signs, symptoms, and/or syndromes compiled from materials reported in the literature. The initial view of each lesion was preset in terms of its location and size, surrounding surface and sectional (magnetic resonance) neuroanatomy, and labeling of lesion and neuroanatomy. In addition, a glossary of neurological disorders was compiled and for each disorder materials from textbooks were included to provide neurological description. This atlas of neurological disorders is potentially useful to a wide variety of users ranging from medical students, residents and nurses to general practitioners, neuroanatomists, neuroradiologists and neurologists, as it contains both normal (surface and sectional) brain anatomy and pathology correlated with neurological disorders presented in a visual and interactive way.

  17. Trends in Mitochondrial Therapeutics for Neurological Disease. (United States)

    Leitão-Rocha, Ana; Guedes-Dias, Pedro; Pinho, Brígida R; Oliveira, Jorge M A


    Neuronal homeostasis is critically dependent on healthy mitochondria. Mutations in mitochondrial DNA (mtDNA), in nuclear-encoded mitochondrial components, and age-dependent mitochondrial damage, have all been connected with neurological disorders. These include not only typical mitochondrial syndromes with neurological features such as encephalomyopathy, myoclonic epilepsy, neuropathy and ataxia; but also secondary mitochondrial involvement in neurodegenerative disorders such as Alzheimer's, Parkinson's and Huntington's disease. Unravelling the molecular aetiology of mitochondrial dysfunction opens new therapeutic prospects for diseases thus far lacking effective treatments. In this review we address recent advances on preventive strategies, such as pronuclear, spindle-chromosome complex, or polar body genome transfer to replace mtDNA and avoid disease transmission to newborns; we also address experimental mitochondrial therapeutics aiming to benefit symptomatic patients and prevent disease manifestation in those at risk. Specifically, we focus on: (1) gene therapy to reduce mutant mtDNA, such as anti-replicative therapies and mitochondriatargeted nucleases allowing favourable heteroplasmic shifts; (2) allotopic expression of recoded wild-type mitochondrial genes, including targeted tRNAs and xenotopic expression of cognate genes to compensate for pathogenic mutations; (3) mitochondria targeted-peptides and lipophilic cations for in vivo delivery of antioxidants or other putative therapeutics; and (4) modulation of mitochondrial dynamics at the level of biogenesis, fission, fusion, movement and mitophagy. Further advances in therapeutic development are hindered by scarce in vivo models for mitochondrial disease, with the bulk of available data coming from cellular models. Nevertheless, wherever available, we also address data from in vivo experiments and clinical trials, focusing on neurological disease models.

  18. Pomegranate: a fruit that ameliorates metabolic syndrome. (United States)

    Medjakovic, Svjetlana; Jungbauer, Alois


    Pomegranate is an ancient fruit that is still part of the diet in the Mediterranean area, the Middle East, and India. Health-promoting effects have long been attributed to this fruit. Modern research corroborates the use of pomegranate as a folk remedy for diabetes and metabolic syndrome, and is responsible for a new evaluation of nutritional and pharmaceutical aspects of pomegranate in the general public. In the last decade, industry and agricultural production have been adapted to meet higher market demands for pomegranate. In vivo and in vitro studies have demonstrated that pomegranate exerts hypoglycaemic effects, including increased insulin sensitivity, inhibition of α-glucosidase, and impact on glucose transporter type 4 function, but is also responsible for a reduction of total cholesterol, and the improvement of blood lipid profiles, as well as anti-inflammatory effects through the modulation of peroxisome proliferator-activated receptor pathways. These effects may also explain how pomegranate-derived compounds function in the amelioration of adverse health effects caused by metabolic syndrome. Pomegranate contains polyphenols such as ellagitannins and anthocyanins, as well as phenolic acids, fatty acids and a variety of volatile compounds. Ellagitannins are some of the most prevalent compounds present in pomegranate, and may be responsible for certain benevolent characteristics associated with pomegranate. A brief overview of rising health problems due to obesity will be provided, followed by characterisation of the biological activity, bioavailability, and safety of pomegranate and pomegranate-derived compounds. Although the fruit is consumed in many countries, epidemiological and clinical studies are unavailable. Additional research is necessary to corroborate the promise of current in vivo and in vitro findings.

  19. [Intermediate neurological development of 60 neonates weighing 1500 grams or less at birth. Predictive value of initial findings (clinical aspects, electroencephalograms and brain imaging)]. (United States)

    Jeannot, E; Fessard, C; Parain, D; Ensel, P; Le Dosseur, P; Brossard, V; Pierre, G; Devaux, A M; Thiebot, J


    60 low birthweight (less than or equal to 1,500 g) are distributed according to existence or not, and intensity of brain disturbances, during the neonatal period; appreciated by neurological examinations, early EEG and brain imaging during the second month of life. At 18 months, at least, neurological outcome is normal for 46 children (but 6 had transient neuromotor anomalies), 14 have sequelae (7 mild, 7 major). All children with clinical neurological examination carried out during the neonatal period are normal at follow up. It is true also for the children without EEG anomaly and normal brain imaging. The early prediction of neurological outcome can be made easily with consideration of these three data. Standardised test are proposed, during the neonatal period, for these low birth weight infants.

    Full Text Available BACKGROUND Alcoholism is characterised by alcohol tolerance, signs and symptoms of withdrawal and continued use in spite of insidious physical or psychological consequences. Chronic alcohol abuse causes several distinct diseases affecting many organs; however, the alcohol affecting the brain is the most significant factor for maintaining this alcohol abuse. The neurological complications of alcoholism include both the peripheral and the central nervous system like the alcohol withdrawal syndrome which includes alcohol withdrawal seizures, delirium tremens, alcohol hallucinosis. The other neurological complications are the alcoholic peripheral neuropathy, alcoholic myopathy, Wernicke encephalopathy, combination of Wernicke encephalopathy with Korsakoff ’s psychosis. Not all alcoholics are alike. The degree of impairment differs from individual to individual and the aetiology of a particular disease has different origins for different people. In the current scenario, it is still a subject of active research as to what characteristic features makes certain group of alcoholics more vulnerable to brain damage. MATERIALS AND METHODS The present study was undertaken under the Department of General Medicine, Govt. Stanley Hospital, Chennai. The study consists of 150 patients with history of alcohol intake satisfying the inclusion and exclusion criteria, presenting in medical OPD/wards/ICU, after proper consent were subjected to questionnaires, complete physical examination and relevant laboratory investigations as per proforma. A prospective observational study design was chosen and descriptive statistics was done for all data and suitable statistical tests of comparison for a period of 6 months. RESULTS It was found that alcohol withdrawal seizures and acute hallucinosis were the most common neurological sequelae seen. Acute hallucinosis was more prevalent in younger age group, whereas complications like alcohol polyneuropathy, Wernicke

  1. Psychologic theories in functional neurologic disorders. (United States)

    Carson, A; Ludwig, L; Welch, K


    In this chapter we review key psychologic theories that have been mooted as possible explanations for the etiology of functional neurologic symptoms, conversion disorder, and hysteria. We cover Freudian psychoanalysis and later object relations and attachment theories, social theories, illness behavior, classic and operant conditioning, social learning theory, self-regulation theory, cognitive-behavioral theories, and mindfulness. Dissociation and modern cognitive neuroscience theories are covered in other chapters in this series and, although of central importance, are omitted from this chapter. Our aim is an overview with the emphasis on breadth of coverage rather than depth.

  2. Improving hand hygiene after neurological injury. (United States)

    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.

  3. Hypnosis as therapy for functional neurologic disorders. (United States)

    Deeley, Q


    Suggestion in hypnosis has been applied to the treatment of functional neurologic symptoms since the earliest descriptions of hypnosis in the 19th century. Suggestion in this sense refers to an intentional communication of beliefs or ideas, whether verbally or nonverbally, to produce subjectively convincing changes in experience and behavior. The recognition of suggestion as a psychologic process with therapeutic applications was closely linked to the derivation of hypnosis from earlier healing practices. Animal magnetism, the immediate precursor of hypnosis, arrived at a psychologic concept of suggestion along with other ideas and practices which were then incorporated into hypnosis. Before then, other forms of magnetism and ritual healing practices such as exorcism involved unintentionally suggestive verbal and nonverbal stimuli. We consider the derivation of hypnosis from these practices not only to illustrate the range of suggestive processes, but also the consistency with which suggestion has been applied to the production and removal of dissociative and functional neurologic symptoms over many centuries. Nineteenth-century practitioners treated functional symptoms with induction of hypnosis per se; imperative suggestions, or commands for specific effects; "medical clairvoyance" in hypnotic trance, in which patients diagnosed their own condition and predicted the time and manner of their recovery; and suggestion without prior hypnosis, known as "fascination" or "psychotherapeutics." Modern treatments largely involve different types of imperative suggestion with or without hypnosis. However, the therapeutic application of suggestion in hypnosis to functional and other symptoms waned in the first half of the 20th century under the separate pressures of behaviorism and psychoanalysis. In recent decades suggestion in hypnosis has been more widely applied to treating functional neurologic symptoms. Suggestion is typically applied within the context of other

    Despite major advances in the understanding and in the genetics of several diseases of the developing brain, early prediction of the neurological prognosis of brain abnormality discovered in utero or of white matter damage discovered in a preterm neonate remains particularly difficult. Advances in prenatal diagnosis and the increased rate of survival of extremely preterm infants who are at higher risk of developing white matter damage underline the critical and urgent need for reliable predictive techniques. New imaging techniques such as diffusion-weighted imaging, magnetic resonance spectroscopy or functional MRI applied to the fetus represent promising tools in this perspective. (orig.)

    Budrys, Valmantas


    World-famous Mexican painter Frida Kahlo is an impressive example of a professional artist whose artistic subject matter was extremely influenced by her chronic, severe illness. Many of her best-known works depict her physical and mental suffering. She was one of those very uncommon artists who dared to show their nude, sick body. This chapter describes and explains the biographical events and works of Frida Kahlo that are closely related to neurology: congenital anomaly (spina bifida), poliomyelitis, spine injury, and neuropathic pain.

  6. [Joseph Babinski's contribution to neurological symptomatology]. (United States)

    Furukawa, Tetsuo


    Joseph Babinski (1857-1932) was an excellent clinician. André Breton, a French poet, described Babinski's way of clinical examination in his Manifeste du surréalisme (1924), which vividly revealed Babinski's meticulous character. Babinski is well known by his eponymous Babinski reflex. Although some predecessors had described this phenomenon briefly, its meaning was interpreted by Babinski. His contribution to neurological symptomatology was not restricted to his plantar skin reflex, but also to other wide area. In this article, symptoms described by Babinski, i.e. plantar skin reflex, cerebellar symptoms including cerebellar asynergy, adiadochokinesis, dysmetria, cerebellar catalepsy, and rising sign, platysma sign, anosognosia are explained and are critically discussed.

  7. Sedation in neurological intensive care unit

    Directory of Open Access Journals (Sweden)

    Birinder S Paul


    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.

  9. A focus on adolescence to reduce neurological, mental health and substance-use disability. (United States)

    Davidson, Leslie L; Grigorenko, Elena L; Boivin, Michael J; Rapa, Elizabeth; Stein, Alan


    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.

  10. Respiratory muscle strength and training in stroke and neurology: a systematic review. (United States)

    Pollock, Ross D; Rafferty, Ged F; Moxham, John; Kalra, Lalit


    We undertook two systematic reviews to determine the levels of respiratory muscle weakness and effects of respiratory muscle training in stroke patients. Two systematic reviews were conducted in June 2011 using a number of electronic databases. Review 1 compared respiratory muscle strength in stroke and healthy controls. Review 2 was expanded to include randomized controlled trials assessing the effects of respiratory muscle training on stroke and other neurological conditions. The primary outcomes of interest were maximum inspiratory and expiratory mouth pressure (maximum inspiratory pressure and maximum expiratory pressure, respectively). Meta-analysis of four studies revealed that the maximum inspiratory pressure and maximum expiratory pressure were significantly lower (P muscle training on maximum inspiratory pressure in neurological patients compared with control subjects (weighted mean difference 6·94 cmH(2) O) while no effect on maximum expiratory pressure. Respiratory muscle strength appears to be impaired after stroke, possibly contributing to increased incidence of chest infection. Respiratory muscle training can improve inspiratory but not expiratory muscle strength in neurological conditions, although the paucity of studies in the area and considerable variability between them is a limiting factor. Respiratory muscle training may improve respiratory muscle function in neurological conditions, but its clinical benefit remains unknown.

    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 Anti-phospholipids syndrome (APS is considered a non inflammatory auto-immune disease with a significant thrombophilic risk with varied clinical manifestations. The purpose of the current study was to investigate the frequency of thrombotic and non-thrombotic events in patients with APS.In this retrospective study, 102 definite APS subjects were recruited (2007-2011 at Alzahra Hospital, Isfahan, Iran. The patients were referred to Multiple Sclerosis Clinic with the diagnosis of definite APS according to 2006 Sydney's criteria. Disorders associated with APS such as pregnancy complication, vascular thrombosis and livedo reticularis (LR were assessed. Neurological signs and symptoms such as cognitive dysfunction were recorded. Data analyses were performed using SPSS software and P < 0.05 were considered to be statistically significant.Our findings showed that majority of female gender, higher rate of ischemic thrombotic stroke and high miscarriage lied in a large number of APS patients.Overall recurrent miscarriage is a common complication among (antiphospholidpid antibody aPL patients. Furthermore, ischemic stroke is the second common neurological manifestations of APS patients.

  13. Wilson's disease and other neurological copper disorders. (United States)

    Bandmann, Oliver; Weiss, Karl Heinz; Kaler, Stephen G


    The copper metabolism disorder Wilson's disease was first defined in 1912. Wilson's disease can present with hepatic and neurological deficits, including dystonia and parkinsonism. Early-onset presentations in infancy and late-onset manifestations in adults older than 70 years of age are now well recognised. Direct genetic testing for ATP7B mutations are increasingly available to confirm the clinical diagnosis of Wilson's disease, and results from biochemical and genetic prevalence studies suggest that Wilson's disease might be much more common than previously estimated. Early diagnosis of Wilson's disease is crucial to ensure that patients can be started on adequate treatment, but uncertainty remains about the best possible choice of medication. Furthermore, Wilson's disease needs to be differentiated from other conditions that also present clinically with hepatolenticular degeneration or share biochemical abnormalities with Wilson's disease, such as reduced serum ceruloplasmin concentrations. Disordered copper metabolism is also associated with other neurological conditions, including a subtype of axonal neuropathy due to ATP7A mutations and the late-onset neurodegenerative disorders Alzheimer's disease and Parkinson's disease.

  14. Heat-shock proteins in clinical neurology. (United States)

    Romi, Fredrik; Helgeland, Geir; Gilhus, Nils Erik


    Heat-shock proteins (HSPs) are antigen-presenting protein-aggregation-preventing chaperones, induced by cellular stress in eukaryotic cells. In this review, we focus on recent HSP advances in neurological disorders. In myasthenia gravis, patients responding to immunosuppressive therapy have reduced serum HSP-71 antibodies. Generalized and ocular myasthenia gravis patients have elevated serum HSP-70 antibodies, indicating common pathogenic mechanisms. In Guillain-Barré syndrome, HSP-70 antibodies are elevated in serum and cerebrospinal fluid, and serum levels are higher than in myasthenia gravis and multiple sclerosis. In multiple sclerosis, serum HSP-27 antibodies are elevated during relapses providing disease activation marker, while α,β-crystallin expression in brain lesions indicates remission phase initiation. In acute stroke, serum HSP-27 antibodies are elevated irrespective of stroke type and duration. In epilepsy, HSP-27 is induced in patients' astrocytes and cerebral blood vessel walls, and α,β-crystallin is expressed in epileptic foci. In neurodegenerative disorders such as Alzheimer dementia and Parkinson's disease, HSPs are upregulated in brain tissue, and α,β-crystallin modulates superoxide dismutase-1 (SOD-1) tissue accumulation in familial amyotrophic lateral sclerosis. HSPs play an important role in antigen-presentation and tolerance development. Antibody-mediated interference with their function alters immune responses causing neuropathology. The role of HSPs in clinical neurology should be the subject of future investigation.

  15. Efficacy of Intravenous Immunoglobulin in Neurological Diseases. (United States)

    Lünemann, Jan D; Quast, Isaak; Dalakas, Marinos C


    Owing to its anti-inflammatory efficacy in various autoimmune disease conditions, intravenous immunoglobulin (IVIG)-pooled IgG obtained from the plasma of several thousands individuals-has been used for nearly three decades and is proving to be efficient in a growing number of neurological diseases. IVIG therapy has been firmly established for the treatment of Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, and multifocal motor neuropathy, either as first-line therapy or adjunctive treatment. IVIG is also recommended as rescue therapy in patients with worsening myasthenia gravis and is beneficial as a second-line therapy for dermatomyositis and stiff-person syndrome. Subcutaneous rather than intravenous administration of IgG is gaining momentum because of its effectiveness in patients with primary immunodeficiency and the ease with which it can be administered independently from hospital-based infusions. The demand for IVIG therapy is growing, resulting in rising costs and supply shortages. Strategies to replace IVIG with recombinant products have been developed based on proposed mechanisms that confer the anti-inflammatory activity of IVIG, but their efficacy has not been tested in clinical trials. This review covers new developments in the immunobiology and clinical applications of IVIG in neurological diseases.

  16. Clinical applications of intravenous immunoglobulins in neurology (United States)

    Hughes, R A C; Dalakas, M C; Cornblath, D R; Latov, N; Weksler, M E; Relkin, N


    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-Aβ antibody titres associated with decreased Aβ 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

  17. Drug treatment of vertigo in neurological disorders

    Full Text Available Vertigo is a common symptom in everyday clinical practice. The treatment depends on the specific etiology. Vertigo may be secondary to inner ear pathology, or any existing brainstem or cerebellar lesion but may also be psychogenic. Central vertigo is a consequence of a central nervous system lesion. It is often associated with a focal neurological deficit. Peripheral vertigo is secondary to dysfunction of the peripheral vestibular system and is usually characterized by an acute vertigo with loss of balance, sensation of spinning in the space or around self, and is exaggerated with changes of the head and body position; no other neurological deficit is present. Some medications may also cause vertigo. Depending on the cause of the vertigo, drugs with different mechanisms of action, physical therapy, psychotherapy, as well as surgery may be used to combat this disabling malady. Symptomatic treatment has a particularly important role, regardless of the etiology of vertigo. We reviewed the current medications recommended for patients with vertigo, their mechanisms of action and their most frequent side effects.

  19. Modelling toxicity induced Neurological disorders in Zebrafish

    Directory of Open Access Journals (Sweden)

    Benin Joseph


    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.

  20. Neurologic conditions causing lameness in companion animals. (United States)

    McDonnell, J J; Platt, S R; Clayton, L A


    Animals presented with non-weight-bearing lameness are a diagnostic challenge for the veterinarian. It is extremely important to distinguish between orthopedic and neurologic causes of lameness, because the diagnostic and therapeutic plans can be quite different. Myopathies can be confused with orthopedic disease because of gait abnormalities and associated muscle pain. Common myopathies seen in companion animal medicine include polymyositis, muscular dystrophy, endocrine and infectious myopathies, and myasthenia gravis. Lameness caused by disease of the nerve root or nerve is confused with orthopedic disease because of the disturbances of a nerve's sensory distribution (nerve-root signature) or disruption of the motor innervation. The diseases of the nerve root or nerve discussed are lateralized intervertebral disk disease, spinal cord neoplasia, malignant peripheral nerve sheath tumors, and traumatic neuropathies. The diagnosis of these diseases requires careful attention to the signalment, a complete history, and a thorough physical examination focusing on the neurologic and orthopedic components. Ancillary testing should be selected based on these results and a minimum database. Electrodiagnostic testing, radiography, and advanced imaging may help to localize the lesion more precisely and sometimes to confirm the diagnosis. Surgical exploration and histopathology often provide the definitive diagnosis. These cases of non-weight-bearing lameness are a diagnostic challenge, but when successful resolution can be reached, it is gratifying to the clinician, client, and patient.

    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.

  2. Chapter 42: neurology and the neurological sciences in the German-speaking countries. (United States)

    Isler, Hansruedi


    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.

    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.

  7. Zinc Deficiency in Humans and its Amelioration

    Directory of Open Access Journals (Sweden)

    Yashbir Singh Shivay


    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

  8. Green tea epigallo-catechin-galleate ameliorates the development of obliterative airway disease. (United States)

    Liang, Olin D; Kleibrink, Bjoern E; Schuette-Nuetgen, Katharina; Khatwa, Umakanth U; Mfarrej, Bechara; Subramaniam, Meera


    Lung transplantation has the worst outcome compared to all solid organ transplants due to chronic rejection known as obliterative bronchiolitis (OB). Pathogenesis of OB is a complex interplay of alloimmune-dependent and -independent factors, which leads to the development of inflammation, fibrosis, and airway obliteration that have been resistant to therapy. The alloimmune-independent inflammatory pathway has been the recent focus in the pathogenesis of rejection, suggesting that targeting this may offer therapeutic benefits. As a potent anti-inflammatory agent, epigallo-catechin-galleate (EGCG), a green tea catechin, has been very effective in ameliorating inflammation in a variety of diseases, providing the rationale for its use in this study in a murine heterotopic tracheal allograft model of OB. Mice treated with EGCG had reduced inflammation, with significantly less neutrophil and macrophage infiltration and significantly reduced fibrosis. On further investigation into the mechanisms, inflammatory cytokines keratinocyte (KC), interleukin-17 (IL-17), and tumor necrosis factor-α (TNF-α), involved in neutrophil recruitment, were reduced in the EGCG-treated mice. In addition, monocyte chemokine monocyte chemoattractant protein-1 (MCP-1) was significantly reduced by EGCG treatment. Antifibrotic cytokine interferon-γ-inducible protein-10 (IP-10) was increased and profibrotic cytokine transforming growth factor-β (TGF-β) was reduced, further characterizing the antifibrotic effects of EGCG. These findings suggest that EGCG has great potential in ameliorating the development of obliterative airway disease.

  9. Vitamin B6 in clinical neurology. (United States)

    Bernstein, A L


    Many conditions in clinical neurology may be responsive to pyridoxine as a therapeutic agent. The current difficulty is in trying to isolate the conditions that are most likely to respond. Treating seizures is a major part of a neurologic practice. Our current therapeutic agents are only partially successful and limited by multiple side effects. One problem is that patients often have to take these agents for an entire lifetime, further raising the risk of toxicity. If pyridoxine supplementation can improve the efficacy of currently used medications, it will be gladly accepted into our therapeutic arsenal. Headache, chronic pain, and depression all appear to run together in many of our patients. The observations that serotonin deficiency is a common thread between them and that pyridoxine can raise serotonin levels open a wide range of therapeutic options. Small studies have been carried out with mixed success. Comparison with amitriptyline in the treatment of headache appears to show about equal efficacy, although side effects would be expected to be more of a problem with the amitriptyline. Behavioral disorders are relatively common and continue to be a major problem, disrupting the lives of the patients and their families. Current treatments are not acceptable to most people because of the risk of side effects with long-term usage. If, as Dr. Feingold suggests, many of these problems are caused by "toxic" exposures to chemicals that are pyridoxine antagonists, supplementation at early ages may reduce the incidence of hyperactivity and aggressive behavior. This raises the question of safety. Is pyridoxine safe for long-term use in large segments of the population, including children? The studies on children with Down's syndrome and autism, utilizing much higher doses than are used for other therapeutic purposes, seem to indicate relative safety if carefully monitored. Studies involving large population groups with carpal tunnel syndrome, all adults, using 100

  10. Sir Charles Ballance: pioneer British neurological surgeon. (United States)

    Stone, J L


    Sir Charles A. Ballance (1856-1936) began his medical career at St. Thomas's Hospital the University College, London, England, in 1875, receiving honors in every subject and a gold medal in surgery. Victor Horsley (1857-1916) and Ballance were classmates at the University and in the later 1880s began work together at the Brown Institute and the National Hospital, Queen Square. In addition to important studies on vascular surgery, Ballance was involved in primate work on cerebral localization with lifelong friends Charles Beevor, Charles Sherrington, David Ferrier, and others. In June of 1887, Ballance assisted Horsley at Queen Square in the successful removal of an extramedullary spinal cord tumor. Horsley was about to abandon the operation, but his friend urged the removal of one lamina higher and the tumor was discovered. Ballance, a demonstrator in anatomy, realized the spinal cord segments lay higher in relation to the vertebral bodies than was generally appreciated. Ballance popularized the operation of radical mastoidectomy for advanced middle ear infection (1890), standardized an approach to drain or excise temporal brain abscesses, and was the first to clearly understand the neurological signs of cerebellar abscess (1894). Ballance also devised cranial base approaches to attack infectious thrombophlebitis of the lateral, petrosal, and cavernous sinuses. He was the first to completely remove an acoustic tumor (1894); 18 years later, the patient remained well. Ballance also drained a posterior fossa subdural hematoma (1906) and successfully sectioned the auditory nerve for Meniere's syndrome (1908). Ballance's operative experience with both supra- and infratentorial brain lesions included approximately 400 cases, which are detailed in his 1907 book, Some Points in the Surgery of the Brain and Its Membranes. His two-volume set, Essays on the Surgery of the Temporal Bone (1919), remains a brilliantly written and illustrated classic. Ballance was an expert on

  13. Thymosin β4 as a restorative/regenerative therapy for neurological injury and neurodegenerative diseases. (United States)

    Chopp, Michael; Zhang, Zheng Gang


    Thymosin β4 (Tβ4) promotes CNS and peripheral nervous system (PNS) plasticity and neurovascular remodeling leading to neurological recovery in a range of neurological diseases. Treatment of neural injury and neurodegenerative disease 24 h or more post-injury and disease onset with Tβ4 enhances angiogenesis, neurogenesis, neurite and axonal outgrowth, and oligodendrogenesis, and thereby, significantly improves functional and behavioral outcomes. We propose that oligodendrogenesis is a common link by which Tβ4 promotes recovery after neural injury and neurodegenerative disease. The ability to target many diverse restorative processes via multiple molecular pathways that drive oligodendrogenesis and neurovascular remodeling may be mediated by the ability of Tβ4 to alter cellular expression of microRNAs (miRNAs). However, further investigations on the essential role of miRNAs in regulating protein expression and the remarkable exosomal intercellular communication network via exosomes will likely provide insight into mechanisms of action and means to amplify the therapeutic effects of Tβ4.

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

    Directory of Open Access Journals (Sweden)

    James B Aimone


    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.

  15. [Reliability of neurological assessment scales in patients with stroke]. (United States)

    de Caneda, Marco Aurélio Gralha; Fernandes, Jefferson Gomes; de Almeida, Andrea Garcia; Mugnol, Fabiana Eloisa


    Scales for the assessment of neurological impairment are employed in clinical trials, outcome evaluation and in therapeutic decisions. We evaluated the reliability of the Portuguese version of the Rankin Scale (RS), Barthel Index (BI) and the NIHSS (National Institute of Health Stroke Scale) in 51 stroke patients, estimating the agreement of the results for examiners. The interrater reliability was measured using the Kappa Coefficient and Intraclass Correlation Coefficient. The RS showed moderate, substantial and excellent coefficients of agreement. The BI showed from substantial to excellent coefficients of agreement as a whole and also for its constituents. This scale was stratified in prognostic and functional groups, both presenting coefficients of agreement from substantial to excellent. The NIHSS presented excellent agreement on its total and substantial agreements on its individual items. The NIHSS was also stratified in groups of points, which presented moderate or excellent coefficient, and in groups of congruous items, wich showed a moderate to excellent agreement. These results suggest that the Portuguese version of the RS, BI and the NIHSS present adequate reliability.

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

    Aimone, James B.; Weick, Jason P.


    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.

  18. Atlantic conjunctures in Anglo-American neurology: Lewis H. Weed and Johns Hopkins neurology, 1917-1942. (United States)

    Casper, Stephen T


    The emergence of neurology at Johns Hopkins presents a case study for reconsidering the international and institutional contexts of neurology generally. Using a variety of sources, Hopkins's interwar plans for neurology are presented and contextualized in the international environment of neurology, medical research, and philanthropy. During this period, neurology across the world, especially in Britain, was undergoing vast institutional changes. In order for Hopkins to remain at the forefront of excellence in both medicine and medical education, a program in neurology was deemed essential, and this would seem now to have been an unproblematic advance. Spearheading the project for the establishment of neurology at Hopkins was the dean of the medical school, Lewis H. Weed. Weed attempted from 1919 until 1942 to establish a department of neurology but had only limited success. The fact that finding support proved challenging for Weed and Johns Hopkins casts a provocative light on the broader historiography of neurology and illustrates the important role of the international context in defining neurology professionally.

  19. Amelioration of painful crises in sickle cell disease by venesections. (United States)

    Rombos, Yannis; Tzanetea, Revekka; Kalotychou, Vassiliki; Konstantopoulos, Kostas; Simitzis, Spyros; Tassiopoulos, Thomas; Aessopos, Athanasios; Fessas, Phaedon


    Sickle cell disease patients who acquire iron deficiency may experience a degree of amelioration from painful crises in terms of frequency, severity, and duration. This observation prompted us to identify the potential utility of iron load reduction in the management of this disease. Thirteen sickle cell patients not ameliorated by conventional treatment entered a weekly venesection protocol. Hematological values and painful crises of all degrees of severity were recorded and compared to those of the last 12 months before venesection for each case separately ("historical controls"). A decrease was noted in the frequency and intensity of several types of painful crises. Reduction of iron load by venesection seems to be a simple, safe, side-effect-free, and efficient way of preventing and ameliorating to a large extent painful crises in sickle cell disease. The biological effects of venesection on other parameters of sickle cell disease remain to be determined.

  20. The beginnings of the Southern Child/Pediatric Neurology Society. (United States)

    Dyken, Paul Richard; Bodensteiner, John B


    The founding and early development of the Southern Pediatric Neurology Society was in many ways parallel to that of the Child Neurology Society. The organization started out as the Southern Child Neurology Society but the name was changed at the time of incorporation so as to avoid confusion of identity and purpose with the larger Child Neurology Society. Although there are archives of early days and the later development of the Southern Pediatric Neurology Society, the details have never been set down in a narrative explaining the events that led to the development of the organization. In this paper, we try to produce a written record of the history of the founding and early development of the Southern Pediatric Neurology Society.

  1. Neurology of microgravity and space travel (United States)

    Fujii, M. D.; Patten, B. M.


    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.

  2. Utility of functional MRI in pediatric neurology. (United States)

    Freilich, Emily R; Gaillard, William D


    Functional MRI (fMRI), a tool increasingly used to study cognitive function, is also an important tool for understanding not only normal development in healthy children, but also abnormal development, as seen in children with epilepsy, attention-deficit/hyperactivity disorder, and autism. Since its inception almost 15 years ago, fMRI has seen an explosion in its use and applications in the adult literature. However, only recently has it found a home in pediatric neurology. New adaptations in study design and technologic advances, especially the study of resting state functional connectivity as well as the use of passive task design in sedated children, have increased the utility of functional imaging in pediatrics to help us gain understanding into the developing brain at work. This article reviews the background of fMRI in pediatrics and highlights the most recent literature and clinical applications.

  3. Accommodation of workers with chronic neurologic disorders. (United States)

    Bleecker, Margit L; Barnes, Sheryl K


    The ability to work is important to those with chronic neurologic disorders (CND) and to the aging workforce. Many signs and symptoms are similar in those with CND and normal aging, but may interfere with the ability to work if not appropriately accommodated. This requires the healthcare provider to recognize the specific features of the CND that interferes with work and how it can be accommodated. Review of the American with Disabilities Act and the subsequent amendment informs the healthcare provider as to what is covered under the law and how the disability can be accommodated. Overall employers want to retain qualified employees and therefore accommodating workers is beneficial to both the employee with CND and the employer.

    @@ Lymphomatoid granulomatosis (LG) is a rare EpsteinBarr virus (EBV)-associated systemic granulomatous disease that is characterized by an angiocentric and occasionally angiodestructive polymorphic cellular infiltrate. It most frequently affects the lungs, kidneys,and brain.1,2 Usually the lesions are multi-systemic and multifocal. Central nervous system (CNS) involvement occurs in approximately 30% of affected patients, and patients may present with nonspecific neurological symptoms.3 Although CNS lesions usually appear as a secondary metastasis of pulmonary lesions, in rare conditions, it may be the initial or only manifestation of the disease. In this report, we describe two cases presenting with unifocal mass in the brain, histologically confirmed to be LG,

  5. Protective Effects of Ginseng on Neurological Disorders

    Directory of Open Access Journals (Sweden)

    Wei-Yi eOng


    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.

  6. Neurologic complication after anterior sciatic nerve block. (United States)

    Shah, Shruti; Hadzic, Admir; Vloka, Jerry D; Cafferty, Maureen S; Moucha, Calin S; Santos, Alan C


    The lack of reported complications related to lower extremity peripheral nerve blocks (PNBs) may be related to the relatively infrequent application of these techniques and to the fact that most such events go unpublished. Our current understanding of the factors that lead to neurologic complications after PNBs is limited. This is partly the result of our inability to conduct meaningful retrospective studies because of a lack of standard and objective monitoring and documentation procedures for PNBs. We report a case of permanent injury to the sciatic nerve after sciatic nerve block through the anterior approach and discuss mechanisms that may have led to the injury. Intraneural injection and nerve injury can occur in the absence of pain on injection and it may be heralded by high injection pressure (resistance).

    Full Text Available Central nervous system (CNS restoration is an important clinical challenge and stem cell transplantation has been considered a promising therapeutic option for many neurological diseases. Objective : The present review aims to briefly describe stem cell biology, as well as to outline the clinical application of stem cells in the treatment of diseases of the CNS. Method : Literature review of animal and human clinical experimental trials, using the following key words: “stem cell”, “neurogenesis”, “Parkinson”, “Huntington”, “amyotrophic lateral sclerosis”, “traumatic brain injury”, “spinal cord injury”, “ischemic stroke”, and “demyelinating diseases”. Conclusion : Major recent advances in stem cell research have brought us several steps closer to their effective clinical application, which aims to develop efficient ways of regenerating the damaged CNS.

  8. Dysfunctional HCN ion channels in neurological diseases. (United States)

    DiFrancesco, Jacopo C; DiFrancesco, Dario


    Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed as four different isoforms (HCN1-4) in the heart and in the central and peripheral nervous systems. HCN channels are activated by membrane hyperpolarization at voltages close to resting membrane potentials and carry the hyperpolarization-activated current, dubbed If (funny current) in heart and Ih in neurons. HCN channels contribute in several ways to neuronal activity and are responsible for many important cellular functions, including cellular excitability, generation, and modulation of rhythmic activity, dendritic integration, transmission of synaptic potentials, and plasticity phenomena. Because of their role, defective HCN channels are natural candidates in the search for potential causes of neurological disorders in humans. Several data, including growing evidence that some forms of epilepsy are associated with HCN mutations, support the notion of an involvement of dysfunctional HCN channels in different experimental models of the disease. Additionally, some anti-epileptic drugs are known to modify the activity of the Ih current. HCN channels are widely expressed in the peripheral nervous system and recent evidence has highlighted the importance of the HCN2 isoform in the transmission of pain. HCN channels are also present in the midbrain system, where they finely regulate the activity of dopaminergic neurons, and a potential role of these channels in the pathogenesis of Parkinson's disease has recently emerged. The function of HCN channels is regulated by specific accessory proteins, which control the correct expression and modulation of the neuronal Ih current. Alteration of these proteins can severely interfere with the physiological channel function, potentially predisposing to pathological conditions. In this review we address the present knowledge of the association between HCN dysfunctions and neurological diseases, including clinical, genetic, and physiopathological

  10. Neurologic deficits and arachnoiditis following neuroaxial anesthesia. (United States)

    Aldrete, J A


    Of late, regional anesthesia has enjoyed unprecedented popularity; this increase in cases has brought a higher frequency of instances of neurological deficit and arachnoiditis that may appear as transient nerve root irritation, cauda equina, and conus medullaris syndromes, and later as radiculitis, clumped nerve roots, fibrosis, scarring dural sac deformities, pachymeningitis, pseudomeningocele, and syringomyelia, etc., all associated with arachnoiditis. Arachnoiditis may be caused by infections, myelograms (mostly from oil-based dyes), blood in the intrathecal space, neuroirritant, neurotoxic and/or neurolytic substances, surgical interventions in the spine, intrathecal corticosteroids, and trauma. Regarding regional anesthesia in the neuroaxis, arachnoiditis has resulted from epidural abscesses, traumatic punctures (blood), local anesthetics, detergents, antiseptics or other substances unintentionally injected into the spinal canal. Direct trauma to nerve roots or the spinal cord may be manifested as paraesthesia that has not been considered an injurious event; however, it usually implies dural penetration, as there are no nerve roots in the epidural space posteriorly. Sudden severe headache while or shortly after an epidural block using the loss of resistance to air approach usually suggests pneumocephalus from an intradural injection of air. Burning severe pain in the lower back and lower extremities, dysesthesia and numbness not following the usual dermatome distribution, along with bladder, bowel and/or sexual dysfunction, are the most common symptoms of direct trauma to the spinal cord. Such patients should be subjected to a neurological examination followed by an MRI of the effected area. Further spinal procedures are best avoided and the prompt administration of IV corticosteroids and NSAIDs need to be considered in the hope of preventing the inflammatory response from evolving into the proliferative phase of arachnoiditis.

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

    Institute of Scientific and Technical Information of China (English)

    Lourdes; álvarez-Arellano; Carmen; Maldonado-Bernal


    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.

  12. Acupuncture for neurological disorders in the Cochrane reviews:Characteristics of included reviews and studies

    Deren Wang; Weimin Yang; Ming Liu


    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.

  13. Neurology and rehabilitation in the United Kingdom: a view.


    Greenwood, R


    The relationship between neurology and rehabilitation medicine is discussed. The question "Does rehabilitation work?" is not useful. Rather, it should be asked when and how specific rehabilitation techniques should be applied? A satisfactory solution to these questions will not be found without informed neurological involvement. It is argued that the management of most neurological diseases would be improved if neurologists were more familiar with the principles of rehabilitation medicine. Tw...

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

    Directory of Open Access Journals (Sweden)

    A. Gómez Ibáñez


    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

  15. [Neurological diseases and nutrition -- what can we do?]. (United States)

    Tamási, Péter


    Neurological diseases and nutrition are in complex relationship. In the first part of this review the nutritional consequences of acute neurological diseases is presented, with special emphasis on traumatic injuries of the nervous system and stroke. Nutritional therapy of these patients is described in detail. In addition, chronic, degenerative neurological pathological conditions are also discussed, including nutritional consequences and possibilities of therapy. Some ethical and legal issues are also considered. The second part of this review article describes neurological consequences of nutritional problems, both deficits of macro- and micronutrients and toxic effects.

    Aim: To investigate the effects of caffeic acid on early and delayed injuries after focal cerebral ischemia in rats, and the possible relation to 5-lipoxygenase inhibition. Methods: Transient focal cerebral ischemia was induced by middle cerebral artery occlusion in Sprague-Dawley rats. Caffeic acid (10 and 50 mg/kg) was ip injected for 5 d after ischemia. The brain injuries were observed, and the levels of cysteinyl leukotrienes and leukotriene B4 in the brain tissue were measured. Results: Caffeic acid (50 mg/kg) ameliorated neurological dysfunction and neuron loss, and decreased infarct volume 24 h after ischemia; it attenuated brain atrophy, infarct volume, and particularly astrocyte proliferation 14 d after ischemia. In addition, it reduced the production of leukotrienes (5-lipoxygenase metabolites) in the ischemic hemispheres 3 h and 7 d after ischemia. Conclusion: Caffeic acid has protective effect on both early and delayed injuries after focal cerebral ischemia in rats; and this effect may partly relate to 5-lipoxygenase inhibition.

  17. Transcranial low-level infrared laser irradiation ameliorates depression induced by reserpine in rats. (United States)

    Mohammed, Haitham S


    Transcranial low-level infrared laser is a modality of therapy based on the principle of photons delivered in a non-invasive manner through the skull for the treatment of some neurological conditions such as psychological disorders, traumatic brain injuries, and neurodegenerative diseases among others. In the present study, effects of low-level infrared laser irradiation with different radiation powers (80, 200, and 400 mW, continuous wave) were investigated on normal animals subjected to forced swimming test (FST). Results indicated that there are changes in FST parameters in animals irradiated with laser; the lowest dose provoked a significant increase in animal activity (swimming and climbing) and a significant decrease in animal's immobility, while the highest laser dose resulted in a complete inverse action by significantly increasing animal immobility and significantly decreasing animal activity with respect to control animals. The lowest dose (80 mW) of transcranial laser irradiation has then utilized on animals injected with a chronic dose of reserpine (0.2 mg/kg i.p. for 14 days) served as an animal model of depression. Laser irradiation has successfully ameliorated depression induced by reserpine as indicated by FST parameters and electrocorticography (ECoG) spectral analysis in irradiated animals. The findings of the present study emphasized the beneficial effects of low-level infrared laser irradiation on normal and healthy animals. Additionally, it indicated the potential antidepressant activity of the low dose of infrared laser irradiation.

  20. Electroacupuncture ameliorates learning and memory in rats with cerebral ischemia-reperfusion injury by inhibiting oxidative stress and promoting p-CREB expression in the hippocampus. (United States)

    Lin, Ruhui; Lin, Yukun; Tao, Jing; Chen, Bin; Yu, Kunqiang; Chen, Jixiang; Li, Xiaojie; Chen, Li-Dian


    The present study aimed to investigate the mechanisms by which electroacupuncture (EA) ameliorates learning and memory in rats with cerebral ischemic‑reperfusion (I/R) injury. Focal cerebral ischemia was induced in adult male Sprague‑Dawley (SD) rats by transient middle cerebral artery occlusion (MCAO). Following MCAO surgery, the rats received EA at the Shenting (DU24) and Baihui (DU20) acupoints. The results of the present study demonstrated that treatment with EA significantly ameliorated neurological deficits and reduced cerebral infarct volume (Plearning and memory ability of the rats, and markedly activated the cyclic adenosine monophosphate (cAMP) response element‑binding protein (CREB) signaling pathway, resulting in the inhibition of cerebral cell apoptosis in the ischemic penumbra. Furthermore, EA increased the activity of superoxide dismutase and glutathione peroxidase, the protein expression levels of phosphorylated‑CREB and B‑cell lymphoma 2 (Bcl‑2), and the mRNA expression levels of Bcl‑2. Conversely, EA decreased the levels of malondialdehyde and inhibited the expression levels of Bcl2‑associated X protein. The results of the present study suggest that treatment with EA may result in the amelioration of learning and memory ability in rats with cerebral I/R injury.

  1. Reliability of the Cerebral Performance Category to classify neurological status among survivors of ventricular fibrillation arrest: a cohort study

    Directory of Open Access Journals (Sweden)

    Phelps Randi


    Full Text Available Abstract Background The Cerebral Performance Category (CPC score is widely used in research and quality assurance to assess neurologic outcome following cardiac arrest. However, little is known about the inter- and intra-reviewer reliability of the CPC. Methods We undertook an investigation to assess the inter-reviewer and source document reliability of the CPC among a cohort of survivors from out-of-hospital ventricular fibrillation cardiac arrest (n = 131 in a large metropolitan area between November 1, 2003 and December 31, 2005. Subjects with a CPC of 1 or 2 were classified as favorable outcome and those with CPC 3 or greater were classified as unfavorable outcome. One abstractor first used the discharge summary alone to determine the CPC. All 3 abstractors independently reviewed the entire hospital record. Reliability was assessed by determining the proportion of determinations that agreed between abstractors and the respective kappa statistics. We also evaluated the implications for determining survival with favorable neurological outcome when survival to hospital discharge was 20% and 30%. Results When the entire hospital record was used to determine CPC, favorable neurologic outcome (CPC 1 or 2 was recorded in 92% by abstractor 1, 89% by abstractor 2, and 74% by abstractor 3. Agreement was 96% (kappa = 0.78 between abstractors 1 and 2, 84% (kappa = 0.49 between abstractors 2 and 3, 82% (kappa = 0.38 between abstractors 1 and 3. The 3-way kappa was 0.50. Agreement was 90% (kappa = 0.71 between the discharge summary alone and the entire hospital record. If the results from review of the entire record are applied to a circumstance where survival to discharge is 20%, favorable neurologic status would occur in 18.4% for abstractor 1, 17.8% for abstractor 2, and 14.8% for abstractor 3. For survival to hospital discharge of 30%, favorable neurologic status would occur in 27.6% for abstractor 1, 26.7% for abstractor 2, and 22.2% for abstractor 3

    Odenheimer, Germaine; Borson, Soo; Sanders, Amy E; Swain-Eng, Rebecca J; Kyomen, Helen H; Tierney, Samantha; Gitlin, Laura; Forciea, Mary Ann; Absher, John; Shega, Joseph; Johnson, Jerry


    Professional and advocacy organizations have long urged that dementia should be recognized and properly diagnosed. With the passage of the National Alzheimer's Project Act in 2011, an Advisory Council for Alzheimer's Research, Care, and Services was convened to advise the Department of Health and Human Services. In May 2012, the Council produced the first National Plan to address Alzheimer's disease, and prominent in its recommendations is a call for quality measures suitable for evaluating and tracking dementia care in clinical settings. Although other efforts have been made to set dementia care quality standards, such as those pioneered by RAND in its series Assessing Care of Vulnerable Elders (ACOVE), practitioners, healthcare systems, and insurers have not widely embraced implementation. This executive summary (full manuscript available at reports on a new measurement set for dementia management developed by an interdisciplinary Dementia Measures Work Group (DWG) representing the major national organizations and advocacy organizations concerned with the care of individuals with dementia. The American Academy of Neurology (AAN), the American Geriatrics Society, the American Medical Directors Association, the American Psychiatric Association, and the American Medical Association-convened Physician Consortium for Performance Improvement led this effort. The ACOVE measures and the measurement set described here apply to individuals whose dementia has already been identified and properly diagnosed. Although similar in concept to ACOVE, the DWG measurement set differs in several important ways; it includes all stages of dementia in a single measure set, calls for the use of functional staging in planning care, prompts the use of validated instruments in patient and caregiver assessment and intervention, highlights the relevance of using palliative care concepts to guide care before the advanced stages of illness, and provides evidence-based support

    BACKGROUND This study aimed to treat patients with subaxial cervical facet dislocations with incomplete or without neurological deficit by a prospectively designed surgical protocol and observe the short-term clinical outcomes. MATERIAL AND METHODS Fifty-two consecutive subaxial cervical dislocation patients with incomplete or without neurological deficit were enrolled. The surgical strategy was determined based on whether or not the initial anterior closed reduction was successful and whether or not the patients were simultaneously combined with traumatic disc herniation (TDH). Postoperative radiographs were used to assess the reduction and fusion, and kyphosis and lordosis of cervical spines were calculated. The neck pain was assessed by visual analog scale. Body function and neurologic status was evaluated according to the Neck Disability Index and classification of American Spinal Injury Association. Clinical and radiologic outcomes were compared before and after the surgery and during the follow-up. The average follow-up period was 23 months. RESULTS Five patients with TDH and 17 with non-TDH were successfully treated by a single anterior approach, 22 non-TDH patients by a posterior-anterior approach, and another eight TDH patients by an anterior-posterior-anterior approach. No neurologic deterioration or other severe adverse events occurred postoperatively. The kyphosis angle of the dislocated levels was well restored after surgery, and the neck pain was significantly relieved as well. The neurologic status was obviously improved, and bony fusion was obtained in all patients within one-year follow-up. CONCLUSIONS Our prospectively designed surgical strategy is effective for the treatment of patients with subaxial cervical dislocation with incomplete or without neurological deficit.

    The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (palcohol abuse (pdiabetes, S. aureus (pdiabetes mellitus (palcoholism (palcohol abuse (p<0.05), craniocerbral trauma (p<0.05) and less common in meningitis with pneumococcal etiology (p<0.05).

    To analyze the outcome of urgent carotid endarterectomy (CEA) performed within less than six hours in patients with crescendo transient ischemic attack (TIA) and stroke in progression. From January 1998 to December 2008, 58 urgent CEAs were done for acute neurological ischemic events--46 patients with crescendo TIA and 12 patients with stroke in progression. Brain computed tomography (CT) was done prior and after the surgery. Disability level was assessed prior to and after urgent CEA using modified Rankin scale. Median follow-up was 42.1 ± 16.6 months. In the early postoperative period stroke rate was 0% for the patients in crescendo TIA group while in patients with stroke in progression group 3 patients (25%) had positive postoperative brain CT, yet neurological status significantly improved. Mid-term stroke rate was 2.2% in crescendo TIA group and 8.3% in stroke in progression group. In the early postoperative period there were no lethal outcomes, mid-term mortality was 8.3% in stroke in progression while in crescendo TIA group lethal outcomes were not observed. In conclusion, based on our results urgent CEA is a safe and effective treatment option for patients with crescendo TIA and stroke in progression with acceptable rate of postoperative complications.

  6. Clinical problems in neurodevelopmental diagnosis: a 7-year neurological and psychological follow-up study of low risk preterm infants. (United States)

    Fedrizzi, E; Zuccarino, M L; Vizziello, P


    24 selected urban middle class low risk preterm infants and 10 full term infants have been followed up to the age of 7 years in a prospective neurodevelopmental study. The aim was to find out whether the neurological and behavioral peculiarities of the preterm infant fall within the range of variability of sign and function development or whether they are the clinical features of minor neurological dysfunction. The infants were assessed neurologically according to Amiel-Tison at 3, 6, 9 and 12 months of corrected age and by Touwen's examination for minor neurological dysfunction at 3, 5 and 7 years. They were assessed psychologically at 6, 9, 12 and 36 months on Griffiths' Developmental Scale and at 7 years on the Wechsler Bellevue Scale. 33% of the sample was lost to follow-up. The outcome of neurological assessment was as follows: no major sequelae such as cerebral palsy or mental deficiency; 50% had transient neurological anomalies (TNA) during the first year of life, lasting more than 6 months in 16.7%; no minor neurological dysfunctions were detected at 5 and 7 years but the non optimal signs scores were higher in infants of low gestational age. The scores on the Griffiths scale were poorer in the preterm infants between 6 months and 5 years of corrected age, especially in the performance and hearing-speech areas. Performance failures seemed to be related to the duration and type of TNA in the first year of life. General, verbal and performance quotients on the WISC at 7 years were normal and there were no learning or behavior problems. The mild TNA found in low risk preterm infants in the first year of life appear to be of no predictive value for school age problems.

  8. Social buffering ameliorates conditioned fear responses in female rats. (United States)

    Ishii, Akiko; Kiyokawa, Yasushi; Takeuchi, Yukari; Mori, Yuji


    The stress experienced by an animal is ameliorated when the animal is exposed to distressing stimuli along with a conspecific animal(s). This is known as social buffering. Previously, we found that the presence of an unfamiliar male rat induced social buffering and ameliorated conditioned fear responses of a male rat subjected to an auditory conditioned stimulus (CS). However, because our knowledge of social buffering is highly biased towards findings in male subjects, analyses using female subjects are crucial for comprehensively understanding the social buffering phenomenon. In the present studies, we assessed social buffering of conditioned fear responses in female rats. We found that the estrus cycle did not affect the intensity of the rats' fear responses to the CS or their degree of vigilance due to the presence of a conspecific animal. Based on these findings, we then assessed whether social buffering ameliorated conditioned fear responses in female rats without taking into account their estrus cycles. When fear conditioned female rats were exposed to the CS without the presence of a conspecific, they exhibited behavioral responses, including freezing, and elevated corticosterone levels. By contrast, the presence of an unfamiliar female rat suppressed these responses. Based on these findings, we conclude that social buffering can ameliorate conditioned fear responses in female rats.

  11. Spinal fractures in patients with ankylosing spinal disorders: a systematic review of the literature on treatment, neurological status and complications. (United States)

    Westerveld, L A; Verlaan, J J; Oner, F C


    The ankylosed spine is prone to fracture after minor trauma due to its changed biomechanical properties. Although many case reports and small series have been published on patients with ankylosing spondylitis (AS) suffering spine fractures, solid data on clinical outcome are rare. In advanced diffuse idiopathic skeletal hyperostosis (DISH), ossification of spinal ligaments also leads to ankylosis. The prevalence of AS is stable, but since DISH may become more widespread due to its association with age, obesity and type 2 diabetes mellitus, a systematic review of the literature was conducted to increase the current knowledge on treatment, neurological status and complications of patients with preexisting ankylosed spines sustaining spinal trauma. A literature search was performed to obtain all relevant articles concerning the outcome of patients with AS or DISH admitted with spinal fractures. Predefined parameters were extracted from the papers and pooled to study the effect of treatment on neurological status and complications. Ninety-three articles were included, representing 345 AS patients and 55 DISH patients. Most fractures were localized in the cervical spine and resulted from low energy impact. Delayed diagnosis often occurred due to patient and doctor related factors. On admission 67.2% of the AS patients and 40.0% of the DISH patients demonstrated neurologic deficits, while secondary neurological deterioration occurred frequently. Surgical or nonoperative treatment did not alter the neurological prospective for most patients. The complication rate was 51.1% in AS patients and 32.7% in DISH patients. The overall mortality within 3 months after injury was 17.7% in AS and 20.0% in DISH. This review suggests that the clinical outcome of patients with fractures in previously ankylosed spines, due to AS or DISH, is considerably worse compared to the general trauma population. Considering the potential increase in prevalence of DISH cases, this condition may

    Bong-Su Kang; Gene Sung; May Kim-Tenser; Nerses Sanossian


    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. Art, passion, and neurosurgery: the role of the Society of Neurological Surgeons in academic neurosurgery. (United States)

    Dempsey, Robert J


    Neurosurgery is at a crossroads in a time of economic uncertainty. It is also a time of remarkable potential for innovation resulting in dramatic improvement in the way neurosurgeons care for patients and the quality of outcomes. Analysis of this key time point of neurosurgical history is drawn from reflections for a presidential address to the Society of Neurological Surgeons. It is the author's opinion that the best of academic neurosurgery must and will accept this challenge by developing not only the research but also the creativity and art of what neurosurgeons do for maximal patient benefit in research, educational, and clinical missions.

  19. Enterovirus 71 infection-associated acute flaccid paralysis: a case series of long-term neurologic follow-up. (United States)

    Lee, Hsiu-Fen; Chi, Ching-Shiang


    The authors undertook long-term neurologic outcomes of 27 patients aged 0 to 15 years with enterovirus 71-related acute flaccid paralysis from June 1998 to July 2012. Motor function outcome was graded from class I (complete recovery) to class V (permanent paralytic limbs). Twelve of 20 patients (60%) who received intravenous immunoglobulin for treatment of acute flaccid paralysis had motor function outcomes in classes III to V. The median duration of follow-up was 6 months, during which time 7 of 13 patients (54%) with central nervous system infection, 3 of 6 patients (50%) with autonomic nervous system dysregulation, and 3 of 8 patients (37%) with heart failure showed motor function outcomes in classes III to V. These findings suggested that the usage of intravenous immunoglobulin and the severity of disease staging at disease onset might not be able to predict long-term motor function outcomes.

  20. Neurological manifestations of calcific aortic stenosis

    Directory of Open Access Journals (Sweden)

    I. V. Egorov


    Full Text Available Despite being thoroughly studied, senile aortic stenosis (AS remains a disease that is frequently underestimated by Russian clinicians. Meanwhile, its manifestations can not only deteriorate quality of life in patients, but can also be poor prognostic signs. The most common sequels of this disease include heart failure and severe arrhythmias. However, there may be also rare, but no less dangerous complications: enteric bleeding associated with common dysembriogenetic backgrounds, infarctions of various organs, the basis for which is spontaneous calcium embolism, and consciousness loss episodes. The latter are manifestations of cardiocerebral syndrome. Apart from syncope, embolic stroke may develop within this syndrome. There is evidence that after syncope occurs, life expectancy averages 3 years. Global practice is elaborating approaches to the intracardiac calcification prevention based on the rapid development of new pathogenetic ideas on this disease. In particular, it is clear that valvular calcification is extraskeletal leaflet ossification rather than commonplace impregnation with calcium salts, i.e. the case in point is the reverse of osteoporosis. This is the basis for a new concept of drug prevention of both calcification and the latter-induced heart disease. But the view of senile AS remains more than conservative in Russia. The paper describes a clinical case of a rare complication as cerebral calcium embolism and discusses the nature of neurological symptoms of the disease, such as vertigo and syncope.

  1. Determination of mental competency, a neurological perspective. (United States)

    Kirshner, Howard S


    This article discusses the evaluation of the capacity of a person to make informed decisions about financial matters, independent living, and informed consent for medical treatment and research. Determination of capacity is a function for which most physicians have little training. The determination of competency for a general medical patient may be assessed by a combination of a bedside mental status examination such as the MMSE and a questionnaire such as the Aid To Capacity Evaluation (ACE 1999). For patients with focal neurological deficits such as aphasia, further evaluation of specific cognitive and language functions is needed; Alexander (Arch Neurol 45:23-6, 1988) suggested 7 specific functions to be assessed. Finally, in dementing illnesses, evaluation by the MMSE and a questionnaire such as the CCTI, or Capacity to Consent to Treatment Instrument (Marson et al. Arch Neurol 52:949-54, 1995) is needed. Dementia includes several separate syndromes of neurodegenerative disease, and in many of these conditions, focal deficits such as aphasia may necessitate a more thorough neuropsychological evaluation.

  2. [Facial and eye pain - Neurological differential diagnosis]. (United States)

    Kastrup, O; Diener, H-C; Gaul, C


    Head and facial pain are common in neurological practice and the pain often arises in the orbit or is referred into the eye. This is due to the autonomic innervation of the eye and orbit. There are acute and chronic pain syndromes. This review gives an overview of the differential diagnosis and treatment. Idiopathic headache syndromes, such as migraine and cluster headache are the most frequent and are often debilitating conditions. Trigemino-autonomic cephalalgias (SUNCT and SUNA) have to be taken into account, as well as trigeminal neuralgia. Trigemino-autonomic headache after eye operations can be puzzling and often responds well to triptans. Every new facial pain not fitting these categories must be considered symptomatic and a thorough investigation is mandatory including magnetic resonance imaging. Infiltrative and neoplastic conditions frequently lead to orbital pain. As a differential diagnosis Tolosa-Hunt syndrome and Raeder syndrome are inflammatory conditions sometimes mimicking neoplasms. Infections, such as herpes zoster ophthalmicus are extremely painful and require rapid therapy. It is important to consider carotid artery dissection as a cause for acute eye and neck pain in conjunction with Horner's syndrome and bear in mind that vascular oculomotor palsy is often painful. All of the above named conditions should be diagnosed by a neurologist with special experience in pain syndromes and many require an interdisciplinary approach.

  3. Speech and neurology-chemical impairment correlates (United States)

    Hayre, Harb S.


    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.

    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.

  5. Coenzyme Q10 and Neurological Diseases

    Directory of Open Access Journals (Sweden)

    Gabriele Siciliano


    Full Text Available Coenzyme Q10 (CoQ10, or ubiquinone is a small electron carrier of the mitochondrial respiratory chain with antioxidant properties. CoQ10 supplementation has been widely used for mitochondrial disorders. The rationale for using CoQ10 is very powerful when this compound is primary decreased because of defective synthesis. Primary CoQ10 deficiency is a treatable condition, so heightened “clinical awareness” about this diagnosis is essential. CoQ10 and its analogue, idebenone, have also been widely used in the treatment of other neurodegenerative disorders. These compounds could potentially play a therapeutic role in Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, Friedreich’s ataxia, and other conditions which have been linked to mitochondrial dysfunction. This article reviews the physiological roles of CoQ10, as well as the rationale and the role in clinical practice of CoQ10 supplementation in different neurological diseases, from primary CoQ10 deficiency to neurodegenerative disorders.

    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.

  7. Development of an oximeter for neurology (United States)

    Aleinik, A.; Serikbekova, Z.; Zhukova, N.; Zhukova, I.; Nikitina, M.


    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.

  8. Multiple roles of metalloproteinases in neurological disorders. (United States)

    Yang, Yi; Hill, Jeff W; Rosenberg, Gary A


    Once thought to mainly act in brain to remodel the extracellular matrix, the family of metalloproteinases is important in many normal and pathological processes in the nervous system. Matrix metalloproteinases (MMPs) and A disintegrin and metalloproteinases (ADAMs) are the two major families of metalloproteinases in the brain. MMPs are comprised of several related enzymes that act on extracellular molecules. Normally, they are important in angiogenesis and neurogenesis in development. In neuroinflammatory illnesses, they disrupt the basal lamina and tight junction proteins to open the blood-brain barrier (BBB). ADAMs are important in neuroinflammation through activation of tumor necrosis factor-α (TNF-α) and their action as secretases that modulate the action of receptors on the cell surface. Four tissue inhibitors of metalloproteinases (TIMPs) are the main inhibitors of the MMPs and ADAMs. Recently, MMPs were found to affect DNA repair processes by an unexpected intranuclear action. MMPs and ADAMs have been implicated in the pathophysiology of neurodegenerative diseases such as Alzheimer's disease and vascular cognitive impairment. Growing literature on the functions of MMPs and ADAMs in the central nervous system is opening up new and exciting areas of research that may lead to novel approaches to treatment of neurological diseases.

  9. Control of Abnormal Synchronization in Neurological Disorders

    Directory of Open Access Journals (Sweden)

    Oleksandr V. Popovych


    Full Text Available In the nervous system synchronization processes play an important role, e.g., in the context of information processing and motor control. However, pathological, excessive synchronization may strongly impair brain function and is a hallmark of several neurological disorders. This focused review addresses the question of how an abnormal neuronal synchronization can specifically be counteracted by invasive and non-invasive brain stimulation as, for instance, by deep brain stimulation for the treatment of Parkinson's disease, or by acoustic stimulation for the treatment of tinnitus. On the example of coordinated reset (CR neuromodulation we illustrate how insights into the dynamics of complex systems contribute to successful model-based approaches, which use methods from synergetics, nonlinear dynamics, and statistical physics, for the development of novel therapies for normalization of brain function and synaptic connectivity. Based on the intrinsic multistability of the neuronal populations induced by spike timing-dependent plasticity (STDP,CR neuromodulation utilizes the mutual interdependence between synaptic connectivity and dynamics of the neuronal networks in order to restore more physiological patterns of connectivity via desynchronization of neuronal activity. The very goal is to shift the neuronal population by stimulation from anabnormally coupled and synchronized state to a desynchronized regime with normalized synaptic connectivity, which significantly outlasts the stimulation cessation, so that long-lasting therapeutic effects can be achieved.

    Grell, Kathrine; Meersohn, Andrea; Schüz, Joachim


    Several studies suggest a link between electric injuries and neurological diseases, where electric shocks may explain elevated risks for neuronal degeneration and, subsequently, neurological diseases. We conducted a retrospective cohort study on the risk of neurological diseases among people...... in Denmark who had survived an electric accident in 1968-2008. The cohort included 3,133 people and occurrences of neurological diseases were determined by linkage to the nationwide population-based Danish National Register of Patients. The numbers of cases observed at first hospital contact in the cohort...... were compared with the respective rates of first hospital contacts for neurological diseases in the general population. We observed significantly increased risks for peripheral nerve diseases (standardized hospitalization ratio (SHR), 1.66; 95% confidence interval (CI), 1.22-2.22), for migraine (SHR, 1...

    Tamanna Roshan Lal


    Full Text Available Gaucher disease, the most common lysosomal storage disorder, is due to a deficiency in the enzyme glucocerebrosidase. This leads to the accumulation of its normal substrate, glucocerebroside, in tissue macrophages, affecting the hematological, visceral, bone and neurologic systems. Gaucher disease is classified into three broad phenotypes based upon the presence or absence of neurological involvement: type 1 (non-neuronopathic, type 2 (acute neuronopathic, and type 3 (subacute neuronopathic. Phenotypically, there is a wide spectrum of visceral and neurological manifestations. Enzyme replacement is effective in managing the visceral disease; however, treating the neurological manifestations has proved to be more challenging. This review discusses the various neurological manifestations encountered in Gaucher disease, and provides a brief overview regarding the treatment and ongoing research challenges.

  13. Neurological Complications Resulting from Non-Oral Occupational Methanol Poisoning (United States)

    Lee, Seung Keun; Gil, Young-Eun; Kim, Hyunjoo; Choi, Jun Young


    Methanol poisoning results in neurological complications including visual disturbances, bilateral putaminal hemorrhagic necrosis, parkinsonism, cerebral edema, coma, or seizures. Almost all reported cases of methanol poisoning are caused by oral ingestion of methanol. However, recently there was an outbreak of methanol poisoning via non-oral exposure that resulted in severe neurological complications to a few workers at industrial sites in Korea. We present 3 patients who had severe neurological complications resulting from non-oral occupational methanol poisoning. Even though initial metabolic acidosis and mental changes were improved with hemodialysis, all of the 3 patients presented optic atrophy and ataxia or parkinsonism as neurological complications resulting from methanol poisoning. In order to manage it adequately, as well as to prevent it, physicians should recognize that methanol poisoning by non-oral exposure can cause neurologic complications. PMID:28049252

  14. Orthosis for thoracolumbar burst fractures without neurologic deficit: A systematic review of prospective randomized controlled trials

    Gabriel Alcala-Cerra


    Full Text Available Background: Traditionally, conservative treatment of thoracolumbar (TL burst fractures without neurologic deficit has encompassed the application of an extension brace. However, their effectiveness on maintaining the alignment, preventing posttraumatic deformities, and improving back pain, disability and quality of life is doubtful. Objective: The objective was to identify and summarize the evidence from randomized controlled trials (RCTs to determine whether bracing patients who suffer TL fractures adds benefices to the conservative manage without bracing. Materials and Methods: Seven databases were searched for relevant RCTs that compared the clinical and radiological outcomes of orthosis versus no-orthosis for TL burst fractures managed conservatively. Primary outcomes were: (1 Loss of kyphotic angle; (2 failure of conservative management requiring subsequent surgery; and (3 disability and pain outcomes. Secondary outcomes were defined by health-related quality of life and in-hospital stay. Results: Based on predefined inclusion criteria, only two eligible high-quality RCTs with a total of 119 patients were included. No significant difference was identified between the two groups regarding loss of kyphotic angle, pain outcome, or in-hospital stay. The pooled data showed higher scores in physical and mental domains of the Short-Form Health Survey 36 in the group treated without orthosis. Conclusion and Recommendation: The current evidence suggests that orthosis could not be necessary when TL burst fractures without neurologic deficit are treated conservatively. However, due to limitations related with number and size of the included studies, more RCTs with high quality are desirable for making recommendations with more certainty.

    In this paper, we report our experience from a prospective study in 40 ischemic stroke patients admitted during the last two years at University Department of Neurology Stroke Unit, Banja Luka Clinical Center, in order to assess the safety and efficacy of thrombolytic therapy, the impact of age, sex and risk factors, and functional outcome at 6 months of intravenous tissue plasminogen activator treatment. According to the National Institutes of Health Stroke Scale, there were 5 mild, 22 moderate and 13 severe stroke cases in the study group. The outcome measures at 6 months of thrombolytic treatment were taken in 38 (100%) patients, yielding a Functional Independent Measure score > or=90 (good clinical outcome) in 21 (52.50%) and modified Rankin Score < or =2 (good clinical outcome) in 22 (55%) patients. The rate of symptomatic intracerebral hemorrhage in tissue plasminogen activator treated patients was 5%, with a mortality rate of 17.50%. The outcomes were comparable with those found in the NINDS t-PA trial. Current guidelines recommend a 'door-to-needle' time of less than 60 minutes and emphasize that 'time is brain'.

  17. French school of neurology in the 19 th and first half of the 20th century, and its influence in Brazil

    Directory of Open Access Journals (Sweden)

    Marleide da Mota Gomes


    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.

  18. tDCS-enhanced motor and cognitive function in neurological diseases. (United States)

    Flöel, Agnes


    Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation tool that is now being widely used in neuroscientific and clinical research in humans. While initial studies focused on modulation of cortical excitability, the technique quickly progressed to studies on motor and cognitive functions in healthy humans and in patients with neurological diseases. In the present review we will first provide the reader with a brief background on the basic principles of tDCS. In the main part, we will outline recent studies with tDCS that aimed at enhancing behavioral outcome or disease-specific symptoms in patients suffering from mild cognitive impairment, Alzheimer's disease, movement disorders, and epilepsy, or persistent deficits after stroke. The review will close with a summary statement on the present use of tDCS in the treatment of neurological disorders, and an outlook to further developments in this realm. tDCS may be an ideal tool to be administered in parallel to intensive cognitive or motor training in neurological disease, but efficacy for the areas of activities and participation still needs to be established in controlled randomized trials. Its use in reducing disease-specific symptoms like dystonia or epileptic seizures is still unclear.

  19. Practical considerations on the use of rituximab in autoimmune neurological disorders (United States)

    Kosmidis, Mixalis L.; Dalakas, Marinos C.


    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

  1. Nissen fundoplication in children with profound neurologic disability. High risks and unmet goals. (United States)

    Smith, C D; Othersen, H B; Gogan, N J; Walker, J D


    Anti-reflux procedures have been advocated in children with profound neurologic disability referred for feeding gastrostomy when gastroesophageal reflux is present. Facilitation of care, reduction in pneumonia and vomiting, and improvement in the general health and survival of these children have been major goals of fundoplication and gastrostomy. In large pediatric series, these procedures have been reported to have low risk and negligible mortality rates. Recent reports, however, document an increased incidence of sequelae of fundoplication in children with profound neurologic disability. This paper retrospectively reviews a series of 35 nonverbal, nonambulatory pediatric patients undergoing a total of 39 fundoplications (37 Nissen, 1 Thal, and 1 Belsey) over an 11-year period. Neurologic impairment of 17 (49%) patients was acquired, 13 (37%) congenital, and 5 (14%) due to a syndrome. Perioperative complications occurred in six (17%). Three additional complications led to early postoperative death. A fourth early death was unexplained. Fourteen (40%) had recurrent pneumonia, 11 (31%) recurrent vomiting, 8 (23%) choking-gagging-retching complex, and 3 (9%) bowel obstruction requiring laparotomy. Recurrent gastroesophageal reflux was documented in seven (20%) patients. A second ARP was performed in six (17%). There were 14 (40%) late deaths. Although the major goals of anti-reflux procedure are clearly achieved in many severely impaired children with gastroesophageal reflux, the use of Nissen fundoplication to resolve the complications of swallowing disorders and improve outcome with an acceptably low risk in this complex set of patients does not appear to be established.

    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, S�o 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. PMID:21808869

  3. Insight in Psychiatry and Neurology: State of the Art, and Hypotheses. (United States)

    Landi, Paola; Marazziti, Donatella; Rutigliano, Grazia; Dell'Osso, Liliana


    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 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

  7. Functional magnetic resonance imaging in neurology. (United States)

    Auer, Tibor; Schwarcz, Attila; Horváth, Réka A; Barsi, Péter; Janszky, József


    The present contribution discusses the clinical use of functional MRI (fMRI) and its role in the most common neurological diseases. FMRI was found a reliable and reproducible examination tool resulting in a wide distribution of fMRI methods in presurgical evaluation of epilepsy in determining the relationship of eloquent areas and the epileptic focus. Preliminary data suggest that fMRI using memory paradigms can predict the postoperative memory decline in epilepsy surgery by determining whether a reorganization of memory functions took place. Speech-activated fMRI became the most used tool in determining hemispheric dominance. Visual and sensory-motor cortex can also be routinely investigated by fMRI which helps in decision on epilepsy surgery. FMRI combined with EEG is a new diagnostic tool in epilepsy and sleep disorders. FMRI can identify the penumbra after stroke and can provide an additional information on metabolic state of the threatened brain tissue. FMRI has a predictive role in post-stroke recovery. In relapsing-remitting MS an adaptive reorganization can be demonstrated by fMRI affecting the visual, motor, and memory systems, despite preserved functional performance. Much more extensive reorganization can be demonstrated in secondary progressive MS. These findings suggest that the different stages of MS are related to different stages of the reorganization and MS becomes progressive when there is no more reserve capacity in the brain for reorganization. FMRI offers the capability of detecting early functional hemodynamic alterations in Alzheimer's disease before morphological changes. FMRI can be a valuable tool to test and monitor treatment efficacy in AD. FMRI can also provide information about the mechanisms of different therapeutic approaches in Parkinson disorder including drug treatment and deep brain stimulation.

  8. Origins of the sensory examination in neurology. (United States)

    Freeman, Cassiopeia; Okun, Michael S


    Formal testing of sensation as part of the neurological examination followed the improvements in examination techniques as well as advances in neuroscience. By the 1890s, the observation that temperature sense was frequently impaired at the same time that pain was appreciated led to the supposition that the two paths traveled closely. Through the works of Brown-Séquard and Edinger the existence of a crossed afferent tract was verified. The distinction between two sensory pathways was clear by 1898, when van Gehuchten reported a case of syringomyelia and suggested that the pain and temperature fibers were carried anterolaterally and the position sense fibers carried posteriorly in the spinal cord. Many authors describing patients with tabes dorsalis suspected the posterior columns of the spinal cord played a key role in position sense. It is difficult to determine in the 19th century who first employed the use of movements of joints as a test for proprioceptive function; however, Bell in 1826 recognized what he termed a sixth sense, which later was characterized as proprioceptive function. Goldscheider went on to report the degrees of movement that were considered normal for each joint. Although vibratory sense had been described by Cardano and Ingrassia in the 16th century and tests had been developed by Rinne and Rumpf by the 19th century, it was not until 1903 that Rydel and Seiffer found that vibratory sense and proprioceptive sense were closely related and that both senses were carried in the posterior columns of the spinal cord. By 1955, the sensory examination included tests for light-touch, superficial pain, temperature, position sense, vibration, muscle (deep pain), and two-point discrimination. Tests for these sensibilities still remain in use. We will review the origins of the understanding of sensation, which ultimately led to the development of the sensory examination. We will highlight individuals who made important discoveries and observations, as

    Ravikumar A


    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.

  10. Neurologic complication after a roller coaster ride. (United States)

    Sa Leitao, Davi; Mendonca, Dercio; Iyer, Harish; Kao, Cheng-Kai


    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.

  11. Magnetic resonance imaging in neurologic diseases

    Magnetic resonance (MR) imaging with 0.15 Tesla resistive magnet developed by Korea Advanced Institute of Science were performed in 27 patients with various neurologic diseases and compared with x-ray computed tomography (CT). The purpose of the paper is to evaluate the image quality, the diagnostic value and limitation, and the optimal pulse sequence of MR imagings with a resistive magnet. The MR images were obtained by using a variety of pulse sequence with spin echo technique including saturation recovery. T2-weighted spin echo, and/or inversion recovery with various pulse repetition (TR) and echo delay (TE) times. The MR imaging demonstrated the capability of detecting the lesions shown on CT in al cases and also detected an additional finding in one case (multiple sclerosis) which was not seen on CT. The MR imaging appeared to be more useful than CT in the evaluation of syringomyelia of spinal cord and white matter disease, while it failed to demonstrated small calcific lesion or inflammatory nodule (less than 1 cm) shown on CT and has shown somewhat poor contrast resolution in the case of meingloma. The spatial resolution of saturation recovery images was similar or superior to CT, whereas the contrast resolution of saturation recovery was inferior to CT. While the saturation recovery images have shown false negative findings in 5 patients (19%), the inversion recovery and T2-weighted spin echo have shown consistently positive findings. The inversive recovery and T2-weighted spin echo images demonstrated better contrast discrimination between normal and pathologic conditions than the saturation recovery images, but somewhat poorer spatial resolution. Authors suggest that the MR images of both the saturation recovery with 300/30 and T2-weighted spin echo with 1000/90 be used as a routine procedure and additional inversion recovery of 1300/300/30 sequence as a option if white matter disease is suspected.

  12. Frontal lobe neurology and the creative mind

    Directory of Open Access Journals (Sweden)

    Leonardo Cruz De Souza


    Full Text Available Concepts from cognitive neuroscience strongly suggest that the prefrontal cortex (PFC plays a crucial role in the cognitive functions necessary for creative thinking. Functional imaging studies have repeatedly demonstrated the involvement of PFC in creativity tasks. Patient studies have demonstrated that frontal damage due to focal lesions or neurodegenerative diseases are associated with impairments in various creativity tasks.However, against all odds, a series of clinical observations has reported the facilitation of artistic production in patients with neurodegenerative diseases affecting PFC, such as frontotemporal dementia (FTD. An exacerbation of creativity in frontal diseases would challenge neuroimaging findings in controls and patients, as well as the theoretical role of prefrontal functions in creativity processes. To explore this paradox, we reported the history of a FTD patient who exhibited the emergence of visual artistic productions during the course of the disease. The patient produced a large amount of drawings, which have been evaluated by a group of professional artists who were blind to the diagnosis. We also reviewed the published clinical cases reporting a change in the artistic abilities in patients with neurological diseases.We attempted to reconcile these clinical observations to previous experimental findings by addressing several questions raised by our review. For instance, to what extent can the cognitive, conative and affective changes following frontal damage explain changes in artistic abilities? Does artistic exacerbation truly reflect increased creative capacities? These considerations could help to clarify the place of creativity - as it has been defined and explored by cognitive neuroscience - in artistic creation and may provide leads for future lesion studies.

    Moos, Walter H; Faller, Douglas V; Harpp, David N; Kanara, Iphigenia; Pernokas, Julie; Powers, Whitney R; Steliou, Kosta


    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

    Chagas disease is an important public health problem in Latin America, and its treatment by chemotherapy with benznidazole (BZ) or nifurtimox remains unsatisfactory. In order to design new alternative strategies to improve the current etiological treatments, in the present work, we comprehensively evaluated the in vitro and in vivo anti-Trypanosoma cruzi effects of clomipramine (CMP) (a parasite-trypanothione reductase-specific inhibitor) combined with BZ. In vitro studies, carried out using a checkerboard technique on trypomastigotes (T. cruzi strain Tulahuen), revealed a combination index (CI) of 0.375, indicative of a synergistic effect of the drug combination. This result was correlated with the data obtained in infected BALB/c mice. We observed that during the acute phase (15 days postinfection [dpi]), BZ at 25 mg/kg of body weight/day alone decreased the levels of parasitemia compared with those of the control group, but when BZ was administered with CMP, the drug combination completely suppressed the parasitemia due to the observed synergistic effect. Furthermore, in the chronic phase (90 dpi), mice treated with both drugs showed less heart damage as assessed by the histopathological analysis, index of myocardial inflammation, and levels of heart injury biochemical markers than mice treated with BZ alone at the reference dose (100 mg/kg/day). Collectively, these data support the notion that CMP combined with low doses of BZ diminishes cardiac damage and inflammation during the chronic phase of cardiomyopathy. The synergistic activity of BZ-CMP clearly suggests a potential drug combination for Chagas disease treatment, which would allow a reduction of the effective dose of BZ and an increase in therapeutic safety.

    Full Text Available To perform a systematic review of studies using remote physical activity monitoring in neurological diseases, highlighting advances and determining gaps.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.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.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.

  16. Immunotherapies for Neurological Manifestations in the Context of Systemic Autoimmunity. (United States)

    Kampylafka, Eleni I; Alexopoulos, Harry; Dalakas, Marinos C; Tzioufas, Athanasios G


    Neurological involvement is relatively common in the majority of systemic autoimmune diseases and may lead to severe morbidity and mortality, if not promptly treated. Treatment options vary greatly, depending on the underlying systemic pathophysiology and the associated neurological symptoms. Selecting the appropriate therapeutic scheme is further complicated by the lack of definite therapeutic guidelines, the necessity to differentiate primary neurological syndromes from those related to the underlying systemic disease, and to sort out adverse neurological manifestations caused by immunosuppressants or the biological agents used to treat the primary disease. Immunotherapy is a sine qua non for treating most, if not all, neurological conditions presenting in the context of systemic autoimmunity. Specific agents include classical immune modulators such as corticosteroids, cyclophosphamide, intravenous immunoglobulin, and plasma exchange, as well as numerous biological therapies, for example anti-tumor necrosis factor agents and monoclonal antibodies that target various immune pathways such as B cells, cytokines, and co-stimulatory molecules. However, experience regarding the use of these agents in neurological complications of systemic diseases is mainly empirical or based on small uncontrolled studies and case series. The aim of this review is to present the state-of-the-art therapies applied in various neurological manifestations encountered in the context of systemic autoimmune diseases; evaluate all treatment options on the basis of existing guidelines; and compliment these data with our personal experience derived from a large number of patients.

    Full Text Available 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.

  18. Frontiers in therapeutic development of allopregnanolone for Alzheimer's disease and other neurological disorders

    Ronald W. Irwin


    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

  19. Chapter 39: an historical overview of British neurology. (United States)

    Rose, F Clifford


    In the UK, neurology stemmed from general (internal) medicine rather than psychiatry. In 1886 the Neurological Society of London was founded, with Hughlings Jackson as its first President. After World War I, Kinnier Wilson was made Physician in Charge of the first independent department of neurology, which was at Westminster Hospital in London. Although before the 17th century there were British doctors who took an interest in diseases of the nervous system, e.g. Gilbertus Anglicus (c. 1230), who distinguished epilepsy from apoplexy, and Bartholomeus Anglicus, whose encyclopedia (c. 1260) provided the first picture of a dissection printed in English, John of Gaddesden (1280-1361) was the first in Britain to produce a manuscript on neurological disorders. Thomas Willis (1621-1675) was the founder of Neurology, being the first to use the term, and was also the leader of the first multidisciplinary team in neurological science, helping to shift attention from the chambers of the brain to the brain substance itself. He wrote seven books, all but the last in Latin, and his second one, Cerebri anatome (1664) was the first on the nervous system to include the brain, spinal cord and peripheral nerves, introducing such new terms as lentiform body, corpus striatum, optic thalamus, inferior olives and peduncles. Most of his neurology was in his fifth book, De anima brutorum (1672). Before Willis the brain was a mystery, but his work laid the foundations for neurological advances. After the 17th century of William Harvey and Thomas Sydenham and the 18th century of William Heberden and Robert Whytt there followed the 19th century of James Parkinson (1755-1824), John Cooke (1756-1838), Sir Charles Bell (1774-1842), Marshall Hall (1790-1856) and Bentley Todd (1809-1860). Besides its "Father," Hughlings Jackson, the giants who established the unique superiority of British neurology were Sir William Gowers, Sir David Ferrier, Kinnier Wilson, Sir Gordon Holmes and Sir Charles

    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.
