    Screen media overuse is associated with negative physical and mental health effects in children. The American Academy of Pediatrics recommends limiting screen media use at home; however, there are no similar guidelines for children's hospitals. This study was conducted to explore caregiver (parent or other guardian) perceptions about screen media use, compare at-home with in-hospital screen media use, and measure screen use among hospitalized children. We obtained data from a convenience cohort of hospitalized children at a single, comprehensive tertiary care children's hospital over 3 periods of 2 weeks each from 2013 to 2014. Home and hospital screen media use was measured through survey and study personnel directly observed hospital screen use. Descriptive statistics are reported and generalized estimating equation was used to identify characteristics associated with screen media use. Observation (n = 1490 observations) revealed screen media on 80.3% of the time the hospitalized child was in the room and awake, and 47.8% of observations with direct attention to a screen. Surveyed caregivers reported their child engaging in significantly more screen media use in the hospital setting as compared with home, and 42% of caregivers reported the amount of screen time used by their child in the hospital was more than they would have liked. Hospitalized children have access to a variety of screen media, and this media is used at rates far higher than recommended by the American Academy of Pediatrics. Children's hospitals should consider developing guidelines for screen media use. Copyright © 2016 by the American Academy of Pediatrics

    Background Patients increasingly use social media to communicate. Their stories could support quality improvements in participatory health care and could support patient-centered care. Active use of social media by health care institutions could also speed up communication and information provision to patients and their families, thus increasing quality even more. Hospitals seem to be becoming aware of the benefits social media could offer. Data from the United States show that hospitals increasingly use social media, but it is unknown whether and how Western European hospitals use social media. Objective To identify to what extent Western European hospitals use social media. Methods In this longitudinal study, we explored the use of social media by hospitals in 12 Western European countries through an Internet search. We collected data for each country during the following three time periods: April to August 2009, August to December 2010, and April to July 2011. Results We included 873 hospitals from 12 Western European countries, of which 732 were general hospitals and 141 were university hospitals. The number of included hospitals per country ranged from 6 in Luxembourg to 347 in Germany. We found hospitals using social media in all countries. The use of social media increased significantly over time, especially for YouTube (n = 19, 2% to n = 172, 19.7%), LinkedIn (n =179, 20.5% to n = 278, 31.8%), and Facebook (n = 85, 10% to n = 585, 67.0%). Differences in social media usage between the included countries were significant. Conclusions Social media awareness in Western European hospitals is growing, as well as its use. Social media usage differs significantly between countries. Except for the Netherlands and the United Kingdom, the group of hospitals that is using social media remains small. Usage of LinkedIn for recruitment shows the awareness of the potential of social media. Future research is needed to investigate how social media lead to improved health

    Objective We aimed to investigate the views of allied health and nursing staff on supporting the communication of children with cerebral palsy (CP) and complex communication needs (CCN) in hospital. Method We conducted 12 focus groups with 49 community- and hospital-based allied health professionals and hospital nurses. Results Participants reported having active roles in supporting children’s seating, mobility, equipment, mealtime management and psychosocial needs, but not in supporting the children’s communication in hospital. Participants described several environmental barriers to supporting children’s augmentative and alternative communication (AAC) in hospital, and suggested a range of strategies to ease communication difficulties at the bedside. Conclusion Results indicate a potential new role for community- and hospital-based health professionals in supporting nurses to implement AAC strategies at the bedside. Supporting nursing staff to remove environmental barriers and use communication technologies might create a more communicatively accessible hospital ward for children with CP and CCN. PMID:24102353

    Background Cost containment is the cornerstone of the Affordable Care Act. Although studies have compared the cost of cerebral aneurysm clipping (CAC) and coiling, they haven’t focused on the identification of drivers of cost after CAC, or the prediction of its magnitude. The objective of the present study was to develop and validate a predictive model of hospitalization cost after CAC. Methods We performed a retrospective study involving CAC patients who were registered in the Nationwide Inpatient Sample (NIS) database from 2005–2010. The two cohorts of ruptured and unruptured aneurysms underwent 1:1 randomization to create derivation and validation subsamples. Regression techniques were used for the creation of a parsimonious predictive model. Results Of the 7,798 patients undergoing CAC, 4,505 (58%) presented with unruptured, and 3,293 (42%) with ruptured aneurysms. The median hospitalization cost was $24,398 (Interquartile Range (IQR), $17,079 – $38,249), and $73,694 (IQR, $46,270 – $115,128) for the two cohorts, respectively. Common drivers of cost identified in the multivariate analyses included: length of stay, number of admission diagnoses and procedures, hospital size and region, and patient income. The models were validated in independent cohorts and demonstrated final R2 very similar to the initial models. The predicted and observed values in the validation cohort demonstrated good correlation. Conclusions This national study identified significant drivers of hospitalization cost after CAC. The presented model can be utilized as an adjunct in the cost containment debate and the creation of data-driven policies. PMID:25583532

    To discover if there have been changes in the treatment time for SAH in our hospital environment. Comparative analysis of 571 patients treated at Hospital Universitari la Fe during 2 different time periods. The SAH-OLD group consisted of 462 patients attended consecutively between April 1997 and March 2005, while SAH-NEW comprised 109 patients attended consecutively between March 2007 and April 2010. We analysed demographic factors, risk factors, severity at time of admission, time to arteriography, diagnosis of aneurysm, use of surgical or endovascular treatment and time to treatment, frequency of neurological complications, in-hospital deaths, and modified Rankin Scale (mRS) at discharge. Mean time to arteriography was 2.18 ± 2.5 days for the SAH-OLD group and 2.37 ± 2.23 days, for the SAH-NEW group (P=.49). Mortality rates for SAH-OLD patients were calculated at 30%, compared to 18.3% in SAH-NEW patients (P=.01). Among patients surviving the hospital stay in the SAH-OLD group, 13.3% had an mRS > 3, compared to 21.3% of survivors in the SAH-NEW group (P=.06). Two hundred forty-five patients in the SAH-OLD group had cerebral aneurysms and 208 were treated (45% of the patient total). Sixty-five of the SAH-NEW patients received treatment (60% of the patient total, P=.007). In the SAH-OLD group, 62.9% of the patients underwent embolisation vs 74.6% in the SAH-NEW group (P=.08). Time to embolisation was 4.7 ± 8.2 days for SAH-OLD patients and 2.12 ± 2.2 days for SAH-NEW patients (P=.01). Twenty-two percent of SAH-OLD patients underwent surgery, compared to 25.4% in the SAH-NEW group (P=.62). Care for SAH patients has improved in this hospital: results include fewer mortalities, a higher number of treatments with a smaller proportion of endovascular treatments, and shorter times to treatment. Elapsed time to arteriography remains stable. Copyright © 2016 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children.

    The objective of this article is to illustrate user characteristics of a hospital's social media structure using analytics and user surveys. A 1-year retrospective analysis was conducted along with an Internet survey of users of the hospital's Facebook, Twitter, and blog. Of the survey respondents (n = 163), 95.7% are female and 4.3% are male; most are ages 50-59 years (31.5%) and 40-49 years (27.8%); and 93.2% are Caucasian. However, the hospital system database revealed 55% female and 37% minority population, respectively. Of the survey respondents, 61.4% reported having a bachelor's degree or higher, whereas only 11.7% reported having a high school degree/equivalent or lower. However, within the hospital patient databases, 93% of patients have a high school degree/equivalent or lower and only 3% have a bachelor's degree or higher in our women's services population. Social media were used to seek personal health information 68.7% (n = 112), to learn about hospital programming 27.6% (n = 45), and to seek family health information 25.2% (n = 41). Respondents younger than 49 years of age were more likely to seek personal health information using social media compared to those 50 years of age and older (p = .02). Respondents with a bachelor's degree or higher education were statistically less likely to search for physician information compared to those less educated individuals (p = .04). We conclude that social media may play an important role in personal health information, especially for young female respondents; however, the survey provides strong evidence that further research is needed to ensure that social network sites provided by hospitals are reaching the full spectrum of health system patients.

    Swollen middle cerebral artery infarction is a life-threatening disease and decompressive craniectomy is improving survival significantly. Despite decompressive surgery, however, many patients are not discharged from the hospital alive. We therefore wanted to search for predictors of early in-hospital death after craniectomy in swollen middle cerebral artery infarction. All patients operated with decompressive craniectomy due to swollen middle cerebral artery infarction at the Department of Neurosurgery, Oslo University Hospital Rikshospitalet, Oslo, Norway, between May 1998 and October 2010, were included. Binary logistic regression analyses were performed and candidate variables were age, sex, time from stroke onset to decompressive craniectomy, NIHSS on admission, infarction territory, pineal gland displacement, reduction of pineal gland displacement after surgery, and craniectomy size. Fourteen out of 45 patients (31%) died during the primary hospitalization (range, 3-44 days). In the multivariate logistic regression model, middle cerebral artery infarction with additional anterior and/or posterior cerebral artery territory involvement was found as the only significant predictor of early in-hospital death (OR, 12.7; 95% CI, 0.01-0.77; p = 0.029). The present study identified additional territory infarction as a significant predictor of early in-hospital death. The relatively small sample size precludes firm conclusions.

    Use of social media has become widespread across the United States. Although businesses have invested in social media to engage consumers and promote products, less is known about the extent to which hospitals are using social media to interact with patients and promote health. The aim was to investigate the relationship between hospital social media extent of adoption and utilization relative to hospital characteristics. We conducted a cross-sectional review of hospital-related activity on 4 social media platforms: Facebook, Twitter, Yelp, and Foursquare. All US hospitals were included that reported complete data for the Centers for Medicare and Medicaid Services Hospital Consumer Assessment of Healthcare Providers and Systems survey and the American Hospital Association Annual Survey. We reviewed hospital social media webpages to determine the extent of adoption relative to hospital characteristics, including geographic region, urban designation, bed size, ownership type, and teaching status. Social media utilization was estimated from user activity specific to each social media platform, including number of Facebook likes, Twitter followers, Foursquare check-ins, and Yelp reviews. Adoption of social media varied across hospitals with 94.41% (3351/3371) having a Facebook page and 50.82% (1713/3371) having a Twitter account. A majority of hospitals had a Yelp page (99.14%, 3342/3371) and almost all hospitals had check-ins on Foursquare (99.41%, 3351/3371). Large, urban, private nonprofit, and teaching hospitals were more likely to have higher utilization of these accounts. Although most hospitals adopted at least one social media platform, utilization of social media varied according to several hospital characteristics.

    News reporting has the potential to modify a community's knowledge of emerging infectious diseases and affect peoples' attitudes and behavior. Here we developed a quantitative approach to evaluate the effects of media on such behavior. Statistically significant correlations between the number of new hospital notifications, during the 2009 A/H1N1 influenza epidemic in the Shaanxi province of China, and the number of daily news items added to eight major websites were found from Pearson correlation and cross-correlation analyses. We also proposed a novel model to examine the implication for transmission dynamics of these correlations. The model incorporated the media impact function into the intensity of infection, and enhanced the traditional epidemic SEIR model with the addition of media dynamics. We used a nonlinear least squares estimation to identify the best-fit parameter values in the model from the observed data. We also carried out the uncertainty and sensitivity analyses to determine key parameters during early phase of the disease outbreak for the final outcome of the outbreak with media impact. The findings confirm the importance of responses by individuals to the media reports, with behavior changes having important consequence for the emerging infectious disease control. Therefore, for mitigating emerging infectious diseases, media reports should be focused on how to guide people's behavioral changes, which are critical for limiting the spread of disease.

    When used effectively, social media benefits hospitals through increased revenue, employee recruitment, and increased customer satisfaction. Although 72% of adults who use the Internet engage in social media, little is known about its prevalence among hospitals and the ways in which hospitals use it. We examined hospital characteristics associated with social media use and how U.S. hospitals use Facebook. Through analysis of websites and Facebook pages, we found that seven in 10 hospitals use social media and that 9% of hospitals with a Facebook page do not provide a link to it from their web page. The odds of social media use were greater in large, urban, nonprofit hospitals; at hospitals affiliated with universities or health systems; and at hospitals that emphasize quality metrics or educational information. Hospitals use Facebook as a dissemination strategy to educate consumers, acknowledge staff, and share news of the hospital's awards. However, the majority of hospitals do not actively engage consumers on Facebook pages. We conclude that this lack of engagement is a lost opportunity to enhance customer service, improve quality of care, and build loyalty. For hospital executives, we illustrate that Facebook is underutilized and that considerable opportunity exists for consumer engagement at a low cost. For policymakers, there is a greater use of social media by nonprofit hospitals, compared to for-profit facilities. As Facebook is most commonly used as an educational tool, it is another example of nonprofit hospitals' heightened focus on health promotion and disease prevention.

    To describe the current epidemiologic, clinical, diagnostic, and prognostic characteristics of cerebral toxoplasmosis in a hospital setting in Dakar. This descriptive and analytic study examined the records of all HIV-positive patients with cerebral toxoplasmosis hospitalized at the infectious disease department at Fann (teaching) Hospital from January 2007 through December 2010. The diagnosis was based on clinical and computed tomography criteria completed by a therapeutic test with Cotrimoxazole. There were 26 cases of cerebral toxoplasmosis during the study period. The sex ratio (F/M) was 1.4. The mean age was 41.5 ± 11.2 years. The clinical signs were predominantly fever (88.5%), headache (77.5%), focal signs (64.5%), and disorders of consciousness (61.5%). Brain lesions were most often multiple (64.3%), with mass effects (54.1%) and peripheral edema (77.8%). Seven of the 26 patients died (lethality rate: 29.1%). Impaired consciousness (p = 0.023), high CD8 T-cell counts (p = 0.009), and anemia (p = 0.003) were significantly associated with a higher mortality rate. Cerebral toxoplasmosis remains a complication of AIDS in Dakar. Anemia, impaired consciousness, and high CD8(+) T cell counts were factors indicative of poor prognosis.

    To evaluate the efficacy of stroke rehabilitation unit in municipal hospitals during the acute phase of cerebral infarction. 77 acute cerebral infarction patients were randomly assigned to stroke rehabilitation unit group and 73 to ordinary group. The NIH stroke scale (NIHSS), activities of daily living (ADL) Barthel index and average hospitalized time were compared in two groups before and after the treatment. The average NIHSS in two groups before treatment were 9.26 and 9.12 respectively (P > 0.05) but became 2.62 and 7.64 after treatment (P < 0.01). The average ADL Barthel index in two groups before the treatment were 52.04 and 53.16 (P > 0.05) but 87.26 and 64.20 after the treatment (P < 0.01). The average hospitalized time in the two groups were 22.25 and 26.67 days (P < 0.05). When stroke rehabilitation unit being applied in the acute phase of cerebral infarction, it showed positive results in the following aspects as: improving the neurological function, capabilities of managing daily life, and also shortening the days of hospitalization.

    Despite recent advancements in post-cardiac arrest resuscitation, the optimal measurement of postarrest outcome remains unclear. We hypothesized that Cerebral Performance Category score can predict the long-term outcome of postarrest survivors who received targeted temperature management during their postarrest hospital care. Retrospective chart review. Two academic medical centers from May 2005 to December 2012. The medical records of 2,417 out-of-hospital and in-hospital patients post cardiac arrest were reviewed to identify 140 of 582 survivors who received targeted temperature management. None. The Cerebral Performance Category scores at hospital discharge were determined by three independent abstractors. The 1-month, 6-month, and 12-month survival of these patients was determined by reviewing hospital records and querying the Social Security Death Index and by follow-up telephone calls. The association of unadjusted long-term survival and adjusted survival with Cerebral Performance Category was calculated. Of the 2,417 patients who were identified to have undergone cardiac arrest, 24.1% (582/2,417) were successfully resuscitated, of whom 24.1% (140/582) received postarrest targeted temperature management. Overall, 42.9% of patients (60/140) were discharged with Cerebral Performance Category 1, 27.1% (38/140) with Cerebral Performance Category 2, 18.6% (26/140) with Cerebral Performance Category 3, and 11.4% (16/140) with Cerebral Performance Category 4. Cerebral Performance Category 1 survivors had the highest long-term survival followed by Cerebral Performance Categories 2 and 3, with Cerebral Performance Category 4 having the lowest long-term survival (p < 0.001, log-rank test). We found that Cerebral Performance Category 3 (hazard ratio = 3.62, p < 0.05) and Cerebral Performance Category 4 (hazard ratio = 12.73, p < 0.001) remained associated with worse survival after adjusting for age, gender, race, shockable rhythm, time to targeted temperature management

Information was gathered related to (a) advantages of social media, (b) disadvantages of social media, (c) barriers to successful use, (d) supports to successful use, and (e) recommendations for other individuals using AAC, support personnel, policy makers, and technology developers. Participants primarily chose to focus on social media as a beneficial tool and viewed it as an important form of communication. The participants did describe barriers to social media use (e.g., technology). Despite barriers, all the participants in this study took an active role in learning to use social media. The results are discussed as they relate to themes and with reference to published literature.

    The aim of this study was to understand the communication needs and experiences of parents and children with cerebral palsy (CP) and complex communication needs (CCN) in hospital. Focus groups with 10 parents and interviews with seven children with CP and CCN were analysed for content themes. Results demonstrated that children often want to communicate directly with hospital staff to: gain attention, answer yes/no, convey basic physical needs, give and receive information, control their environment and participate in preferred activities. Barriers to communication included lack of access to augmentative and alternative communication (AAC), staff preferring to communicate with parents and lack of time to communicate. Results highlight strategies for successful communication, the role of the parents in supporting communication and provision of AAC systems for children in hospital. Policy and practice implications in the preparation of children with CP and CCN for communication in hospital are discussed.

    The Methodist Hospital System has maintained a social media presence on Facebook, Twitter, and YouTube since 2009. After initial unofficial excursions into the world of social media, we discovered that social media can be a useful tool to extend a conversation with our patients and the community at large and share our hospital's culture with a larger base of like-minded people. But with this new power comes a heightened responsibility--platforms that can potentially reach millions of viewers and readers also provide a potential for misuse that can jeopardize patient privacy and place hospitals at risk. Because of their unique restrictions, even hospitals that use the tools regularly have much left to learn about social media. With constant monitoring and stewardship and a commitment to educating staff, hospitals can effectively use social media tools for marketing and education.

    As part of the FEATHERS (Functional Engagement in Assisted Therapy Through Exercise Robotics) project, two motion tracking and one social networking applications were developed for upper limb rehabilitation of stroke survivors and teenagers with cerebral palsy. The project aims to improve the engagement of clients during therapy by using video games and a social media platform. The applications allow users to control a cursor on a personal computer through bimanual motions, and to interact with their peers and therapists through the social media. The tracking applications use either a Microsoft Kinect or a PlayStation Eye camera, and the social media application was developed on Facebook. This paper presents a usability testing of these applications that was conducted with therapists from two rehabilitation clinics. The "Cognitive Walkthrough" and "Think Aloud" methods were used. The objectives of the study were to investigate the ease of use and potential issues or improvements of the applications, as well as the factors that facilitate and impede the adoption of technology in current rehabilitation programs.

    To evaluate the clinical picture and microbiological findings of children hospitalized due to acute otitis media and to analyze how it differs from acute mastoiditis. A retrospective review of the medical records of all children (0-16 years) hospitalized due to acute otitis media in the Department of Otorhinolaryngology at the Helsinki University Hospital, between 2003 and 2012. Comparison with previously published data of children with acute mastoiditis (n=56) from the same institute and period of time. The most common pathogens in the children hospitalized due to acute otitis media (n=44) were Streptococcus pneumoniae (18%), Pseudomonas aeruginosa (16%), Streptococcus pyogenes (14%), and Staphylococcus aureus (14%). One of the most common pathogens of out-patient acute otitis media, Haemophilus influenzae, was absent. Otorrhea was common in infections caused by S. pyogenes and otorrhea via tympanostomy tube in infections caused by P. aeruginosa. In children under 2 years-of-age, the most common pathogens were S. pneumoniae (43%), Moraxella catarrhalis (14%), and S. aureus (7%). S. pyogenes and P. aeruginosa were only found in children over 2 years-of-age. Previous health problems, bilateral infections, and facial nerve paresis were more common in children hospitalized due to acute otitis media, compared with acute mastoiditis, but they also demonstrated lower CRP values and shorter duration of hospital stay. The number of performed tympanostomies and mastoidectomies was also comparatively smaller in the children hospitalized due to acute otitis media. S. aureus was more common and S. pneumoniae, especially its resistant strains, was less common in the children hospitalized due to acute otitis media than acute mastoiditis. Acute otitis media requiring hospitalization and acute mastoiditis compose a continuum of complicated acute otitis media that differs from common out-patient acute otitis media.

    Social media provide new channels for hospitals to engage with communities, a goal of increasing importance as non-profit hospitals face stricter definitions of community benefit under the Affordable Care Act. We describe the variability in social media presence among US children's hospitals and the distribution of their Facebook content curation. Social media data from freestanding children's hospitals were extracted from September-November 2013. Social media adoption was reviewed for each hospital-generated Facebook, Twitter, YouTube, Google+ and Pinterest platform. Facebook page (number of Likes) and Twitter account (number of followers) engagement were examined by hospital characteristics. Facebook posts from each hospital over a 6-week period were thematically characterized. We reviewed 5 social media platforms attributed to 45 children's hospitals and 2004 associated Facebook posts. All hospitals maintained Facebook and Twitter accounts and most used YouTube (82%), Google+ (53%) and Pinterest (69%). Larger hospitals were more often high performers for Facebook (67% versus 10%, p<0.01) and Twitter (75% versus 17%, p<0.05) engagement than small hospitals. The most common Facebook post-themes were hospital promotion 35% (706), education and information 35% (694), community partnership or benefit 24% (474), fundraising 21% (426), and narratives 12% (241). Of health education posts, 73% (509) provided pediatric health supervision and anticipatory guidance. Social media adoption by US children's hospitals was widespread. Beyond its traditional marketing role, social media can serve as a conduit for health education, engagement with communities, including community benefit. Copyright © 2015 Elsevier Inc.

    Cerebral infarction (CI) is still a leading cause of death in Japan. Thus, the management of risk factors for CI as primary prevention is one of the most important tasks in multiphasic health testing and services. To determine whether carotid intima-media thickness (IMT) is a risk for CI, ultrasonographically assessed carotid IMT was compared between normal subjects (N) and subjects with asymptomatic CI (ACI) in 243 subjects who underwent human brain dry dock. ACI was found in 68 people (28.0%). Age, body mass index, and mean blood pressure were higher in ACI than in N. Also, atherogenic index was higher in ACI than in N. Carotid IMT was significantly thicker in ACI than in N. Furthermore, incidence of atherogenic plaque in ACI was significantly higher than that in N. In conclusion, not only aging, obesity, blood pressure, and plasma lipids, but also carotid IMT may be a risk for ACI.

    Data on implementation of stroke guidelines are scarce in Spain. We assessed the quality of diagnosis and prevention measures at discharge in patients admitted to hospital for acute cerebral infarction (ACI) in Spain. Independent audit of clinical records on 1,448 consecutive patients admitted to Spanish hospitals for an ACI, performed in a stratified-random sample of 30 public Spanish hospitals. The number of records evaluated per hospital was adjusted by hospital size. Information collected included demographic variables, cerebrovascular risk factors (CRF), family and personal history of cerebrovascular disease, prior cognitive impairment, subtype of infarction, use of functional and cognitive scales, supplementary investigations performed during hospital stay, recommendations, and treatments prescribed at discharge. No information about the ACI etiology was found in 46% of the clinical records. Information on prior vascular diseases was recorded in 69%. Information about pre-existing cognitive impairment was found only in 27%. The use of neurological scales was reported in only 21.1% of the cases. CRF information was observed in 99.2% of the cases. Antihypertensives and antidiabetic treatment were prescribed in 73.2% and 70% of hypertensives and diabetic patients, respectively. Lipid lowering drugs were prescribed in 57.3% of dislipemic patients. Antithrombotic treatment was prescribed in 82% of patients (antiplatelets 77.5%, oral anticoagulants 18.4%, combined therapy 4.1%). Information regarding CRF therapeutic goal attainments was scarcely registered. There is an inadequate adherence to guideline recommendations for the diagnosis and prevention of ACI in Spain. Particularly, the information included in the history regarding cerebrovascular disease, cognitive evaluation, characterization of cerebral infarction, and treatment and control of CRF should be improved.

    Traumatic brain injury (TBI) is a significant cause of death and severe disability from trauma. Pre-hospital care of patients with TBI may be aided by non-invasive monitoring of cerebral tissue oxygenation. This pilot observational study was designed to assess if cerebral tissue oximetry using near-infrared spectroscopy (NIRS) is feasible in the pre-hospital and transport environment. After ethics committee review, we undertook a feasibility trial in healthy volunteers, transported by road ambulance or helicopter, to assess if monitoring signals could be obtained in the outside environment and during patient transport. A total of 33 road ambulance transports and 32 helicopter transports were undertaken. For monitoring commenced outdoors, 33 of 66 probes applied (50%) provided adequate monitoring signal. For road transports, 33 out of 33 transports (100%) resulted in successful bilateral monitoring for more than 70% of the sampling period. For helicopter transports, four transports were cut short by battery failure during the mission and 24 of 28 transports (85.7%) resulted in successful bilateral monitoring for more than 70% of the sampling period. While patient and transport platform movement did not impact on monitoring signals, exposure to ambient light provided a challenge in obtaining monitoring signals that is nevertheless manageable with increased probe shielding. NIRS monitoring is feasible in the pre-hospital environment, opening up the possibility for further research of the role of this modality in this setting. © 2012 The Authors Acta Anaesthesiologica Scandinavica © 2012 The Acta Anaesthesiologica Scandinavica Foundation.

    Objective: To determine and analyse the characteristics of contrast media adverse reactions (CM-ARs) reported in a hospital. Methods: A retrospective review of CM-ARs from the electronic spontaneous adverse drug reaction (ADR) report system between January 2011 and August 2012 was conducted. CM-ARs were evaluated in terms of causality, severity, preventability and affected organs. Also, agreement and correlation among the tools used to evaluate CM-ARs were analysed. Results: The overall reaction rate was 1.5% (n = 286). In total, 269 CM-ARs were identified. For ADR causality, 96.7% (n = 260) and 98.5% (n = 265) were evaluated as “probable” ADR using the Naranjo probability scale and the World Health Organization–Uppsala Monitoring Centre causality categories, whereas 98.1% (n = 264) were evaluated as “certain” with Korean algorithm v. II. Of these, 91.4% (n = 246) were mild in severity and 96.7% (n = 260) were unpreventable. Most patients (n = 233, 86.7%) could be managed with observation and/or simple treatment. The most frequent reaction (n = 383, 79.5%) was dermatological. Spearman's correlation coefficient was 0.667 (p < 0.01), and the agreement was 98.1% between the Naranjo scale and the World Health Organization–Uppsala Monitoring Centre categories. No relationship was seen between CM-AR severity and gender or between in- and outpatients. Conclusion: In our study, most CM-ARs were mild and managed with simple treatment. However, as the number of patients undergoing CT procedures continues to increase, it is essential to identify and observe patients at risk for CM-ARs to prevent severe ADRs. Advances in knowledge: Continuous careful review of reporting and treatment protocols of CM-ARs is needed to prevent morbidity and mortality. PMID:24191123

    For the treatment of cerebral vasospasm, current therapies have focused on increasing blood flow through blood pressure augmentation, hypervolemia, the use of intra-arterial vasodilators, and angioplasty of proximal cerebral vessels. Through a large case series, we present our experience of treating cerebral vasospasm with a protocol based on maintenance of homeostasis (correction of electrolyte and glucose disturbances, prevention and treatment of hyperthermia, replacement of fluid losses), and the use of intravenous milrinone to improve microcirculation (the Montreal Neurological Hospital protocol). Our objective is to describe the use milrinone in our practice and the neurological outcomes associated with this approach. Large case series based on the review of all patients diagnosed with delayed ischemic neurologic deficits after aneurysmal subarachnoid hemorrhage between April 1999 and April 2006. 88 patients were followed for a mean time of 44.6 months. An intravenous milrinone infusion was used for a mean of 9.8 days without any significant side effects. No medical complications associated with this protocol were observed. There were five deaths; of the surviving patients, 48.9 % were able to go back to their previous baseline and 75 % had a good functional outcome (modified Rankin scale ≤ 2). A protocol using intravenous milrinone, and the maintenance of homeostasis is simple to use and requires less intensive monitoring and resources than the standard triple H therapy. Despite the obvious limitations of this study's design, we believe that it would be now appropriate to proceed with formal prospective studies of this protocol.

    Social media is an important communication channel that can help hospitals and consumers obtain feedback about quality of care. However, despite the potential value of insight from consumers who post comments about hospital care on social media, there has been little empirical research on the relationship between patients' anecdotal feedback and formal measures of patient experience. The aim of the study was to test the association between informal feedback posted in the Reviews section of hospitals' Facebook pages and scores on two global items from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, Overall Hospital Rating and Willingness to Recommend the Hospital. We retrieved star ratings and anecdotal comments posted in Reviews sections of 131 hospitals' Facebook pages. Using a machine learning algorithm, we analyzed 57,985 comments to measure consumers' sentiment about the hospitals. We used regression analysis to determine whether consumers' quantitative and qualitative postings would predict global measures from the HCAHPS survey. Both number of stars and the number of positive comments posted on hospitals' Facebook Reviews sections were associated with higher overall ratings and willingness to recommend the hospital. The findings suggest that patients' informal comments help predict a hospital's formal measures of patient experience. Consistent with crowd wisdom, ordinary consumers may have valid insights that can help others to assess patient experience at a hospital. Given that some people will judge hospital quality based on opinions voiced in social media, further research should continue to explore associations between anecdotal commentary and a variety of quality indicators. Administrators can tap into the wealth of commentary on social media as the forum continues to expand its influence in health care. Comments on social media may also serve as an early snapshot of patient-reported experiences, alerting

    This pilot study aimed to expand the current understanding of how adolescents and young adults with cerebral palsy (CP) and complex communication needs use social media. An online focus group was used to investigate the social media experiences of seven individuals with CP who used Augmentative and Alternative Communication (AAC). Questions posed to the group related to social media: (a) advantages; (b) disadvantages; (c) barriers; (d) supports; and (e) recommendations. Adolescents with CP who use AAC used a range of communication media to participate in daily interactions, including social media. An analysis of the focus group interaction revealed that the participants used social media to: bypass the constraints of face-to-face interactions; communicate for a number of reasons (e.g. maintain relationships, share experiences); and support independent leisure (e.g. playing games, looking at pictures/videos). Despite the advantages, the participants discussed barriers including limitations related to AAC technologies, social media sites and literacy skills. The results suggest that service providers should implement interventions to support social media use, including enhancement of linguistic, operational and strategic competence. Technology manufacturers should focus on improving the designs of AAC apps and social media sites to facilitate access by individuals who require AAC.

    To identify the sources for the exceeding of the upper limit of the AOX (adsorbable organic halogen, X = Cl, Br, I) in hospital waste-water and to estimate the contribution of hospital waste-water to the AOX of municipal waste-water. For several hospitals with different medical directions, the expected AOX-concentration, as far as it is caused by iodine contrast media, was ascertained by the contrast media consumption and the water consumption. The results were compared with the measured AOX concentrations. The AOX-concentration of hospital waste-water varies between 0.41 mg/l and 0.94 mg/l. As a source of AOX iodine contrast media have been identified and may contribute considerably to the AOX. Hospitals with a radiological department may exceed the upper limit of the AOX which has to be observed in German municipal waste-water.

    An increasing number of hospitals and health systems utilize social media to allow users to provide feedback and ratings. The correlation between ratings on social media and more conventional hospital quality metrics remains largely unclear, raising concern that healthcare consumers may make decisions on inaccurate or inappropriate information regarding quality. The purpose of this study was to examine the extent to which hospitals utilize social media and whether user-generated metrics on Facebook(®) correlate with a Hospital Compare(®) metric, specifically 30-day all cause unplanned hospital readmission rates. This was a retrospective cross-sectional study conducted among all U.S. hospitals performing outside the confidence interval for the national average on 30-day hospital readmission rates as reported on Hospital Compare. Participants were 315 hospitals performing better than U.S. national rate on 30-day readmissions and 364 hospitals performing worse than the U.S. national rate. The study analyzed ratings of hospitals on Facebook's five-star rating scale, 30-day readmission rates, and hospital characteristics including beds, teaching status, urban vs. rural location, and ownership type. Hospitals performing better than the national average on 30-day readmissions were more likely to use Facebook than lower-performing hospitals (93.3 % vs. 83.5 %; p < 0.01). The average rating for hospitals with low readmission rates (4.15 ± 0.31) was higher than that for hospitals with higher readmission rates (4.05 ± 0.41, p < 0.01). Major teaching hospitals were 14.3 times more likely to be in the high readmission rate group. A one-star increase in Facebook rating was associated with increased odds of the hospital belonging to the low readmission rate group by a factor of 5.0 (CI: 2.6-10.3, p <  0.01), when controlling for hospital characteristics and Facebook-related variables. Hospitals with lower rates of 30-day hospital-wide unplanned readmissions have

    Primary angioplasty has been introduced for the treatment of symptomatic cerebral vasospasm in patients with subarachnoid hemorrhage (SAH). The data regarding the therapeutic benefit of angioplasty in improving patient outcomes are limited, hence its utilization at hospitals remains controversial and currently is not reimbursed by Medicare or major insurance companies. We analyzed the data from Nationwide Inpatient Sample (NIS), a nationally representative dataset of all admissions in the United States from 2005 to 2007. We analyzed the prevalence of angioplasty procedure for cerebral vasospasm at the national level. In-hospital mortality, discharge status, length of stay, and cost of hospitalization were compared between hospitals performing angioplasty with those not performing angioplasty in multivariable model, adjusted for patient's age, utilization of endovascular aneurysm obliteration, and disease severity. Of the 74,356 estimated patients with nontraumatic SAH, 47% (n = 35,172) were admitted to hospitals that perform angioplasty for cerebral vasospasm and only 1307 patients (3.8%) were treated with angioplasty for vasospasm. In multivariable analysis, after adjustment for patient and hospital characteristics, we found that patients admitted to hospitals performing angioplasty had higher rates of discharge to home without supervision (OR 1.3, 95% CI: 1.1-1.6). There was no difference in in-hospital mortality, length of stay, or cost of hospitalization. Our analysis suggests that the odds of a patient being discharged to home are better at hospitals performing angioplasty for cerebral vasospasm. Provision of angioplasty may be used as a surrogate marker of model of care in management of patients with SAH.

    Background To compare the characteristics and prognostic features of ischemic stroke in patients with diabetes and without diabetes, and to determine the independent predictors of in-hospital mortality in people with diabetes and ischemic stroke. Methods Diabetes was diagnosed in 393 (21.3%) of 1,840 consecutive patients with cerebral infarction included in a prospective stroke registry over a 12-year period. Demographic characteristics, cardiovascular risk factors, clinical events, stroke subtypes, neuroimaging data, and outcome in ischemic stroke patients with and without diabetes were compared. Predictors of in-hospital mortality in diabetic patients with ischemic stroke were assessed by multivariate analysis. Results People with diabetes compared to people without diabetes presented more frequently atherothrombotic stroke (41.2% vs 27%) and lacunar infarction (35.1% vs 23.9%) (P < 0.01). The in-hospital mortality in ischemic stroke patients with diabetes was 12.5% and 14.6% in those without (P = NS). Ischemic heart disease, hyperlipidemia, subacute onset, 85 years old or more, atherothrombotic and lacunar infarcts, and thalamic topography were independently associated with ischemic stroke in patients with diabetes, whereas predictors of in-hospital mortality included the patient's age, decreased consciousness, chronic nephropathy, congestive heart failure and atrial fibrillation Conclusion Ischemic stroke in people with diabetes showed a different clinical pattern from those without diabetes, with atherothrombotic stroke and lacunar infarcts being more frequent. Clinical factors indicative of the severity of ischemic stroke available at onset have a predominant influence upon in-hospital mortality and may help clinicians to assess prognosis more accurately.

    Cerebral toxoplasmosis is common opportunistic infections of central nervous system in AIDS. It occurs most often in case of severe immunosuppression. The aim of this study is to investigate the general characteristics of cerebral toxoplasmosis during HIV infection and AIDS in hospital area in Bamako. It is a retrospective study of 5 years (form January 2001 to December 2005), conducted in the infectious diseases department of Point G Teaching Hospital of Bamako. It concerned all patients infected with HIV, hospitalized for cerebral toxoplasmosis. The diagnosis of cerebral toxoplasmosis was based on clinical, C T and therapeutic arguments. A total of 745 patients investigated, 26 met cerebral toxoplasmosis diagnostic criteria (14 men and 12 women). The rate of cerebral toxoplasmosis in the study population was 3.5%. The average age was 38.1 years (18-58 years). Focused neurological deficit (73.07%), intracranial hypertension signs (69.20%), meningeal syndrome (15.40%), seizures (57.69%) and consciousness disorders (30.80%) were the clinical characteristics. Hypodensity with or without peripheral enhancement images (93.75%) were found on CT. The average rate of CD4 T cells was 98.7cells/mm3 (5-473 cells/mm3). Oropharyngeal candidiasis in 61.53% of cases, intestinal cryptosporidiosis (11.53%), herpes zoster (3.84%) and Pott's disease (3.84%) were the opportunistic infections associated. Cotrimoxazole was used in 88.46% of patients and 3 patients (11.54%) received the standard treatment (Sulfadiazine-Pyrimethamine). Antitoxoplasmic treatment led to a clinical improvement in 84.61% and 4 deaths (15.39%). were recorded. The technical platform for etiological diagnosis of toxoplasmosis is not available at the Point-G Teaching Hospital, so in case of encephalitis signs in a HIV positive patient, CT should be urgently perform and a treatment trial must begin without delay.

    Factors influencing early hospital admission have been described for several stroke types but not for cerebral vein and dural sinus thrombosis (CVT). CVT is more difficult to diagnose than arterial stroke; delay in hospital admission may postpone CVT treatment. The purposes of this study were: (1) to describe the delay between the onset of symptoms and hospital admission of patients with CVT, and (2) to identify the variables that influence that delay. We registered the interval (days) between the onset of symptoms and hospital admission in 91 consecutive patients admitted to 20 Portuguese hospitals between June 1995 and June 1998. We also studied the impact of admission delay on treatments (prescription of anticoagulants and the number of days elapsed between the onset of symptoms and start of anticoagulation and admission). Median admission delay was 4 days. Twenty-two (25%) patients were admitted within 24 h. Two thirds of the patients were admitted within 7 days and 75% within 13 days. In multiple logistic regression analysis, admission within 24 h was positively associated with mental status disorder (delirium or abulia; OR = 4.59; 95% CI = 1.41-14.89) and negatively associated with headache (OR = 0.03; 95% CI = 0.00-0.32). Presentation as isolated intracranial hypertension was associated with admission delay of more than 4 days (OR = 2.63; 95% CI = 0.97-7.14). Papilloedema was associated with an admission delay of more than 13 days (OR = 4.69; 95% CI = 1.61-13.61). There was no association between admission delay and the proportion of anticoagulated patients. The interval between onset of symptoms and start of anticoagulation was shorter in patients admitted earlier (p = 0.0001, for either admission within 24 h, 4 or 13 days). There is a considerable delay until the clinical picture associated with CVT is recognised as justifying hospital admission, especially when patients present with symptoms identical to isolated intracranial hypertension syndrome

A quantitative model using parameters obtained at admission may be a predictor of in-hospital mortality from LHI.This prospective study enrolled all patients with LHI involving >50% of the middle cerebral artery (MCA) admitted to our neurological intensive care unit within 48 hours of symptom onset. Early clinical and radiographic parameters and the baseline CHADS2 score (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke [double weight]) were analyzed regarding their ability to predict patient outcomes.Seventy-seven patients with LHIs were identified, 33 (42.9%) with complete MCA infarction (CMCA), and 44 (57.1%) with incomplete MCA infarction (IMCA). The predictors of CMCA score included: >1/3 early hypodensity in computed tomography findings, hyperdense MCA sign, brain edema, initial National Institutes of Health Stroke Scale (NIHSS) score ≥17, and stroke in progression during the 1st 5 days of admission. The cutoff CMCA score was 2, with a sensitivity of 81.8% and specificity of 70.5%. Mortality score 1, used for predicting in-hospital mortality from LHI, included CMCA and CHADS2 scores ≥4 (sensitivity 100.0%, specificity 57.4%), and mortality score 2 included CMCA and CHADS2 scores ≥4, and NIHSS score ≥26, during the 1st 5 days (sensitivity 100.0%, specificity 91.7%).Patients qualifying for a mortality score of 2 were at high-risk of in-hospital mortality from LHI. These findings may aid in identifying patients who may benefit from invasive therapeutic strategies, and in better describing the characteristics of those at risk of mortality.

    Social media is changing the way in which citizens and health professionals communicate. Previous studies have assessed the use of Health 2.0 by hospitals, showing clear evidence of growth in recent years. In order to understand if this happens in Spain, it is necessary to assess the performance of health care institutions on the Internet social media using quantitative indicators. The study aimed to analyze how hospitals in Spain perform on the Internet and social media networks by determining quantitative indicators in 3 different dimensions: presence, use, and impact and assess these indicators on the 3 most commonly used social media - Facebook, Twitter, YouTube. Further, we aimed to find out if there was a difference between private and public hospitals in their use of the aforementioned social networks. The evolution of presence, use, and impact metrics is studied over the period 2011- 2015. The population studied accounts for all the hospitals listed in the National Hospitals Catalog (NHC). The percentage of hospitals having Facebook, Twitter, and YouTube profiles has been used to show the presence and evolution of hospitals on social media during this time. Usage was assessed by analyzing the content published on each social network. Impact evaluation was measured by analyzing the trend of subscribers for each social network. Statistical analysis was performed using a lognormal transformation and also using a nonparametric distribution, with the aim of comparing t student and Wilcoxon independence tests for the observed variables. From the 787 hospitals identified, 69.9% (550/787) had an institutional webpage and 34.2% (269/787) had at least one profile in one of the social networks (Facebook, Twitter, and YouTube) in December 2015. Hospitals' Internet presence has increased by more than 450.0% (787/172) and social media presence has increased ten times since 2011.

    The purpose of this observational study of social media in sports medicine was to investigate and analyze the presence and shared content of anterior cruciate ligament (ACL) patients, sports surgeons, and top orthopaedic hospitals on popular social media streams. A search of 2 public domains (Instagram and Twitter) was performed over a 6-month period. ACL surgery ("#aclsurgery") was selected for the Instagram-based patient analysis after exclusion of veterinary ACL operations. A binary scoring system was used for media format, time (preoperatively or postoperatively), perioperative period (within 1 week of surgery), tone (positive or negative), return-to-work reference, return-to-play reference, rehabilitation reference, surgical-site reference, satisfaction reference, and dissatisfaction reference; perspective of the media was noted as well. A sample of 97 National Football League team surgeons was used for analysis of physician use in social media outlets and quantified by the number of posts. Hospital analysis categorized a sample of the top 50 orthopaedic hospitals by average number of posts and monthly posting rates with regard to orthopaedics, research, education, and personnel focus. In the patient analysis, 3,145 public posts of human subjects were shared on Instagram. Of these, 92% were personal recovery stories, with an emphasis on postoperative photographs (93%) with a positive tone (88%) more than 1 week after surgery (73%). Posts focused on surgical site (25%), return to play (30%), and postoperative rehabilitation (37%). Of the physicians, 16% had Twitter accounts, with an average of 94 posts per surgeon; none had Instagram accounts. Of the hospitals, 96% had Twitter accounts and 32% had Instagram accounts. Most of the hospital-based Instagram content in the sample was centered on patients or celebrities. Orthopaedic surgery has a large social media presence. Patients emphasize wound appearance, the rehabilitation process, and return to play

    Current application of work system simulation in participatory ergonomics (PE) design includes a variety of different simulation media. However, the actual influence of the media attributes on the simulation outcome has received less attention. This study investigates two simulation media: full-scale mock-ups and table-top models. The aim is to compare, how the media attributes of fidelity and affordance influence the ergonomics identification and evaluation in PE design of hospital work systems. The results illustrate, how the full-scale mock-ups' high fidelity of room layout and affordance of tool operation support ergonomics identification and evaluation related to the work system entities space and technologies & tools. The table-top models' high fidelity of function relations and affordance of a helicopter view support ergonomics identification and evaluation related to the entity organization. Furthermore, the study addresses the form of the identified and evaluated conditions, being either identified challenges or tangible design criteria.

    Within the daily workload at a ward there is a considerable amount of information processing. It is the task of a systematic management of hospital information systems to provide health professionals with the right information in the right place at the right time. This paper deals with the consequences for the management of hospital information systems if health professional workstations are introduced as a means for this information logistic and with the experiences gained in the Heidelberg University Hospital. Health professional workstations are formally defined in the context of a three level graph-based model of hospital information systems. It is found that health professional workstations have communication needs not only on the physical level of computer systems in the hospital information system but also on the logical tool level, which is the level of application systems. On this level communication servers or brokers are of considerable importance. In Heidelberg there are about 200 health professional workstations (MEDIAS) in routine use.

    With greater survival rates, patient-reported outcome measures (PROMs) among survivors of ruptured cerebral aneurysm should be an increasing concern among neurointerventionalists. Prior studies were limited in scale and generalizability. Our study aims were to (1) evaluate the validity of cerebral aneurysm PROMs obtained from social media; (2) determine the persistence of PROMs over time; and (3) determine what PROMs still exist in those with no physical impairments. By engaging national brain aneurysm support groups and using an online questionnaire modeled after the generic EQ-5D instrument, we asked respondents to classify their health in five dimensions including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using a 3-point Likert scale. In 2 months we received 604 responses from 46 states in the USA. Our cohort of ruptured aneurysm respondents reported PROMs similar to previously published series. Over time, headache and anxiety improved while depression, level of exercise, and return to work remained unchanged. We found that memory worsened after 2 years. Among those without any physical impairment, rates of 20.6%, 14.9%, 12.6%, and 23% were seen for significant headaches, significant memory loss, significant depression, and sense of life being negatively affected, respectively. Despite this novel study design, we obtained results comparable to prior studies. These results suggest that many patients with ruptured cerebral aneurysms, regardless of whether they are >2 years after the event and/or free of physical impairment, struggle with a poor quality of life. The latency, scale, and low cost of this study design may accelerate future cerebral aneurysm PROM research. Published by the BMJ Publishing Group Limited.

    Abstract This exploratory study has two aims: (1) to find out if and how social media (SM) applications are used by hospitals in Spain and (2) to assess hospital managers' perception of these applications in terms of their evaluation of them, reasons for use, success factors, and difficulties encountered during their implementation. A cross-sectional survey has been carried out using Spanish hospitals as the unit of analysis. Geographical differences in the use of SM were found. Social networks are used most often by larger hospitals (30% by medium-size, 28% by large-size). They are also more frequently used by public hospitals (19%, p<0.01) than by private ones. Respondents with a negative perception of SM felt that there is a chance they may be abused by healthcare professionals, whereas those with a positive perception believed that they can be used to improve communication both within and outside the hospital. Reasons for the use of SM include the idea of maximizing exposure of the hospital. The results show that Spanish hospitals are only just beginning to use SM applications and that hospital type can influence their use. The perceptions, reasons for use, success factors, and difficulties encountered during the implementation of SM mean that it is very important for healthcare professionals to use SM correctly and adequately.

To understand how much consumers search for such information online on one Internet search engine, whether they mention such information in social media and how positively they view this information. A leading Internet search engine (Google) was the main focus of the study. Google Trends and Google Adwords keyword analyses were performed for national and Californian searches between 1 August 2012 and 31 July 2013 for keywords related to 'top hospital', best hospital', and 'hospital quality', as well as for six specific hospital quality reports. Separately, a proprietary social media monitoring tool was used to investigate blog, forum, social media and traditional media mentions of, and sentiment towards, major public reports of hospital quality in California in 2012. (1) Counts of searches for keywords performed on Google; (2) counts of and (3) sentiment of mentions of public reports on social media. National Google search volume for 75 hospital quality-related terms averaged 610 700 searches per month with strong variation by keyword and by state. A commercial report (Healthgrades) was more commonly searched for nationally on Google than the federal government's Hospital Compare, which otherwise dominated quality-related search terms. Social media references in California to quality reports were generally few, and commercially produced hospital quality reports were more widely mentioned than state (Office of Statewide Healthcare Planning and Development (OSHPD)), or non-profit (CalHospitalCompare) reports. Consumers are somewhat aware of hospital quality based on Internet search activity and social media disclosures. Public stakeholders may be able to broaden their quality dissemination initiatives by advertising on Google or Twitter and using social media interactively with consumers looking

    Intracranial aneurysms constitute a significant part of the caseload for any neurosurgical service. Despite the occurrence of intracranial aneurysms and the availability of advanced diagnostic tools and management options, there is a paucity of published data concerning aneurysm patterns in Kenya. This was a combined retrospective and prospective quantitative descriptive study. Following ethical approval, all patients with cerebral aneurysms seen on computed tomography angiography who presented at Nairobi Hospital between May 2010 and June 2014 were included. A standardized questionnaire was used to collect data on patient characteristics, indications for imaging, and radiologic findings. Analysis was carried out SPSS for Windows version 15.0. The study included 121 patients with a female (71.9%) predominance; most (30.58%) of the patients were aged 50-59 years. There were 151 aneurysms observed, with 85.95% of patients having solitary aneurysms and 14.05% having multiple aneurysms; 82.1% of the aneurysms were located in the anterior circulation. Mean aneurysm size was 6.92 mm, mean neck diameter was 2.79 mm, and the range of diameter/neck ratio was 1-11.88 (mean 1.16). The rate of subarachnoid bleeding displayed an exponential increase with aneurysms 3 mm in size and appeared to plateau thereafter despite increasing aneurysm size. Most (78.8%) of the observed anterior communicating artery aneurysms were ruptured. Most patients were postmenopausal women, who had a higher rate of aneurysms with an elevated risk of rupture for small aneurysms; this suggests that clinicians need to be more vigilant and have a higher index of suspicion in such patients with subtle clinical signs. This study revealed a pattern of aneurysms in accord with previous reports and is expected to serve as a basis for further research on aneurysm management, outcome, and prognostic indicators in the Kenyan population.

    Stem cell research has generated considerable attention for its potential to remediate many disorders of the central nervous system including neurodevelopmental disorders such as autism spectrum disorder (ASD) and cerebral palsy (CP) that place a high burden on individual children, families and society. Here we characterized messaging about the use of stem cells for ASD and CP in news media articles and concurrent dissemination of discoveries through conventional science discourse. We searched LexisNexis and Canadian Newsstand for news articles from the US, UK, Canada and Australia in the period between 2000 and 2014, and PubMed for peer reviewed articles for the same 10 years. Using in-depth content analysis methods, we found less cautionary messaging about stem cells for ASD and CP in the resulting sample of 73 media articles than in the sample of 87 science papers, and a privileging of benefits over risk. News media also present stem cells as ready for clinical application to treat these neurodevelopmental disorders, even while the science literature calls for further research. Investigative news reports that explicitly quote researchers, however, provide the most accurate information to actual science news. The hope, hype, and promise of stem cell interventions for neurodevelopmental disorders, combined with the extreme vulnerability of these children and their families, creates a perfect storm in which journalists and stem cell scientists must commit to a continued, if not even more robust, partnership to promote balanced and accurate messaging.

    Discharge support, although provided for a limited time, is of vital importance in the acute phase care period. Such support is necessary to ensure continuity of care and treatment even after being discharged from the hospital. I acquired both the viewpoints of the family and the nurse of a patient who was about to be discharged from the hospital after cerebral hemorrhage. However, the patient's family and I were not able to decide on a home care plan or hospital-to-home transfer ahead of time because of the unstable condition of the patient, limited care power of the family, and varying discharge plans among the family members. I intended to help in the decision-making process, taking into consideration the patient's best interest. I evaluated the viewpoint of the family and was able to understand situations in which a family member, who assumes the role of a primary care giver, would need guidance in providing home care to the patient.

    To assess whether high cerebral microbleeds (CMBs) are associated with carotid intima-media thickness (CIMT), a marker of systemic atherosclerosis, we cross-sectionally evaluated participants from a community-based study, the I-Lan Longitudinal Aging Study. The participants' demographics and cardiovascular risk factors were determined by questionnaire and/or laboratory measurements. CIMT was measured by ultrasonography. CMBs were assessed by susceptibility-weighted-imaging on 3 T MRI. Of the 962 subjects [62.5(8.6) years, 44.2% men] included, CMBs were found in 134(14.0%) subjects. Among the subjects with identified CMB's, 85(63.4%) had deep or infratentorial (DI) and 49(36.6%) had strictly lobar(SL) CMBs. After the results were adjusted for age and sex, the analysis revealed that hypertension, hyperlipidemia, obesity, and higher triglyceride levels correlated with DI but not SL CMBs. The subjects with DI CMBs also had a higher mean CIMT and higher prevalence of top quartile CIMT. The multivariate analysis demonstrated that high CIMT (top quartile) significantly predicted the presence of DI CMBs (odds ratio = 2.1; 95% confidence interval = 1.3-3.4; P = 0.004), independent of age, sex, cardiovascular risk factors, and other cerebral small vessel diseases, lacune, and white matter hyperintensity. There was no association between CIMT and SL CMBs. Our results support that there are distinct pathogenesis in DI and SL CMBs.

    Many hospitals wish to improve their patients’ experience of care. In order to learn whether social media could be used as a tool to engage patients and to identify opportunities for hospital quality improvement (QI), we solicited patients’ narrative feedback on the Baystate Medical Center (BMC) Facebook page during a three-week period in 2014. Two investigators used directed qualitative content analysis to code comments and descriptive statistics to assess the frequency of selected codes and themes. We identified common themes, including: 1.) comments about staff (17/37 respondents, 45.9%); 2.) comments about specific departments (22/37, 59.5%); 3.) comments on technical aspects of care, including perceived errors and inattention to pain control (9/37, 24.3%); and 4.) comments describing the hospital physical plant, parking, and amenities (9/37, 24.3%). A small number (n=3) of patients repeatedly responded, accounting for 30% (45/148) of narratives. While patient feedback on social media could help to drive hospital QI efforts, any potential benefits must be weighed against the reputational risks, the lack of representativeness among respondents, and the volume of responses needed to identify areas of improvement.

    Little is known about the significance of hospitals as point sources for emission of organic micropollutants into the aquatic environment. A mass flow analysis of pharmaceuticals and diagnostics used in hospitals was performed on the site of a representative Swiss cantonal hospital. Specifically, we analyzed the consumption of iodinated X-ray contrast media (ICM) and cytostatics in their corresponding medical applications of radiology and oncology, respectively, and their discharge into hospital wastewater and eventually into the wastewater of the municipal wastewater treatment plant. Emission levels within one day and over several days were found to correlate with the pharmacokinetic excretion pattern and the consumed amounts in the hospital during these days. ICM total emissions vary substantially from day to day from 255 to 1259 g/d, with a maximum on the day when the highest radiology treatment occurred. Parent cytostatic compounds reach maximal emissions of 8-10 mg/d. A total of 1.1%, 1.4%, and 3.7% of the excreted amounts of the cytostatics 5-fluorouracil, gemcitabine, and 2',2'-difluorodeoxyuridine (main metabolite of gemcitabine), respectively, were found in the hospital wastewater, whereas 49% of the total ICM was detected, showing a high variability among the compounds. These recoveries can essentially be explained by the high amount administered to out-patients (70% for cytostatics and 50% for ICM); therefore, only part of this dose is expected to be excreted on-site. In addition, this study emphasizes critical issues to consider when sampling in hospital sewer systems. Flow proportional sampling over a longer period is crucial to compute robust hospital mass flows.

    Manifested as a reflection of the Internet technology progress, web 2.0 has transformed communication among people to different dimensions while increasing the social use of Internet. Thus, the concept of social media has entered our lives. Blogs, forums, Facebook, Twitter and YouTube applications are but few of the social media platforms with active users exceeding millions. As in many other subjects, these and others are also environments where people share information and their positive or negative experiential views with respect to healthcare issues and services. Hence, the social media communication and exchange of information are deemed influential on the process of receiving health services. In the present study that aims to determine social media use of individuals in their choice of physicians, dentists and hospitals, a survey, as a data collection instrument, has been carried out to 947 residents of the province of Izmir. Individuals participating in the study have stated that they have used social media in choosing a physician (41.9% of the participants), dentist (34.1% of the participants) and hospitals (41.7% of the participants). The study has revealed that individuals are affected by social media in their healthcare choices. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

    Smaller cerebral volumes at hospital discharge in very preterm (VPT) infants are associated with poor neurobehavioral outcomes. Brain growth from the newborn period to middle childhood has not been explored because longitudinal data have been lacking. To examine the pattern of growth of cerebral tissue volumes from hospital discharge to childhood in VPT infants and to determine perinatal risk factors for impaired brain growth and associations with neurobehavioral outcomes at 7 years. Prospective cohort study of VPT infants (<30 weeks' gestation or <1250 g) born between April 11, 2001, and April 26, 2004, and followed up at 7 years' corrected age. The setting was The Royal Women's Hospital and The Royal Children's Hospital, Melbourne, Australia. Of 224 VPT infants and 46 full-term (FT) infants, usable magnetic resonance imaging data at either infancy or 7 years were collected for 214 VPT children (95.5%) and 46 FT children (100%), while 126 VPT children (56.3%) and 31 FT children (67.4%) had usable magnetic resonance imaging data at both time points.

Absolute tissue growth, defined as change in absolute tissue volume, between infancy and 7 years was calculated for cortical gray matter volume (GMV), white matter volume (WMV), and subcortical GMV. IQ, language, and motor function were measured at 7 years. The study cohort comprised 260 participants. Their mean (SD) age was 7.5 (0.2) years, and 49.2% (128 of 260) were female. Early GMV deficits in VPT infants were magnified by 7 years, with less growth than FT controls. Growth differences were 31.4 (95% CI, 14.8-48.1) cm3 for cortical GMV and 1.7 (95% CI, 0.5-2.8) cm3 for subcortical GMV. Within the VPT group, greater growth was observed in boys for cortical GMV (31.9; 95% CI, 16.8-46.9 cm3), WMV (31.7; 95% CI, 19.7-43.7 cm3), and subcortical GMV (1.8; 95% CI, 0.8-2.8 cm3).

    This was to determine the prevalence of acute otitis media in children with pyrexia in an area with malaria endemicity and also the relevance of socio-economic factors on AOM. This prospective study was conducted between January 2004 and June 2005 at the emergency paediatric unit of the hospital among children aged 0-15 years presenting with pyrexia. All the children had full ENT examinations in addition to the evaluation by the emergency paediatricians. Diagnosis of AOM was based on history, examinations and otoscopic findings. Two-hundred children with pyrexia were seen and the age range was 3 months to 15 years (mean 4.73). The male/female ratio was 1.7:1.03 years; 32 had features of AOM. Two third of the children were from the low socio-economic class. AOM with late presentation in the suppurative stage of the disease is a common cause of pyrexia in children with a male preponderance and two third of the children were from the low socio-economic status. There is the need for otoscopic examinations of all pyretic children as the resultant hearing loss is related to difficulties in language acquisition in children below 2 years of age with effects on literacy and school achievement.

    In 2010 the Italian Ministry of Health set out recommendations for the use of social technology and Web 2.0, inviting organisations within the Italian national health service (Servizio Sanitario Nazionale, SSN) to equip themselves with instruments. 1. to ascertain how many local health authorities (Aziende Sanitarie Locali, ASL) and public hospitals have a presence on the most widely used social media websites in Italy: Facebook, Twitter and YouTube; 2. to find out how well the Facebook, Twitter and YouTube pages of ASLs and public hospitals are known among the general population; 3. to find out how ASLs and public hospitals engage with the general public on social media sites. The websites of all ASLs and public hospitals across the country were visited to look for the icons of the social media sites under examination. The data considered were publicly available upon access. A total of 245 websites were analysed. 7.34% ASLs and hospitals had social media accounts. 8 organisations had an account on all three of the social media sites considered in the study. The results show a low presence of ASLs and hospitals on social media. Other studies are needed in this field.

    Cerebral toxoplasmosis is the most common cause of space occupying brain lesion in patients with HIV/AIDS in Brazil. In the post-HAART era, it is responsible for high rates of morbidity and mortality worldwide. This study consists of a case series of 56 patients diagnosed with cerebral toxoplasmosis whose clinical features, brain imaging and cerebrospinal fluid aspects were analyzed. Cerebral toxoplasmosis led to the diagnosis of infection by the human immunodeficiency virus (HIV) in 27 (48.2%) of the patients, while 29 (51.2%) others already knew to be HIV seropositive. However, at the time of diagnosis of cerebral toxoplasmosis, only 9 (16.6%) reported being under antiretroviral therapy and 5 (8.9%) were receiving primary prophylaxis for toxoplasmosis. Headache, strength deficit and fever were the most frequent signs and symptoms throughout the study. Fifty-three patients showed changes consistent with toxoplasmosis in CT or MRI. Thirty-four (60.7%) CSF samples were positive in the indirect haemagglutination test and for the reaction of Toxoplasma gondii IgG ELISA, while 31 (55.4%) were positive in the direct haemagglutination test. Fifty (89.3%) patients underwent first-line treatment for toxoplasmosis. Cerebral toxoplasmosis is still a very relevant neurological disease in individuals with AIDS admitted to neurology emergency departments. Early diagnosis and initiation of empiric treatment and antiretroviral therapy are important for good prognosis. Copyright © 2016 Elsevier B.V. All rights reserved.

    Chronic suppurative otitis media (CSOM) is still a significant health problem in developing countries. Therefore, it was pertinent to determine the local Malawian microbiology in order to guide adequate treatment, avoid complications, and provide records for future reference. The study sought to determine the CSOM-causing microorganisms at Queen Elizabeth Central Hospital in Blantyre, Malawi, and establish their relationship signs and symptoms, and with the demographic pattern of the study. This was a hospital-based cross-sectional descriptive study carried out at the ENT outpatient clinic and the Microbiology Department of Queen Elizabeth Central Hospital.The sample comprised 104 patients with unilateral or bilateral active CSOM, who met the inclusion criteria. All patients were evaluated through a detailed history and clinical examination. Pus samples from draining ears were collected by aspiration with a sterile pipette. The specimens were immediately sent for microbiological analysis. Data were analyzed using SPSS.version 20. The study found that Proteus mirabilis, Pseudomonas aeruginosa, and Staphylococcus aureus were the most prevalent aerobic bacteria, while Bacteroides spp. and Peptostreptococcus spp. were the commonest anaerobic bacteria causing CSOM. These CSOM-causing microorganisms were predominant among males aged 18 years and below. Some CSOM-causing microorganisms were-significantly more so than the others-characteristically associated with each of the following clinical features: quantity of pus drainage, mode of onset, otalgia, hearing loss, location of tympanic membrane perforation, and mucosal appearance.

    Public health officials and policy makers in the United States expend significant resources at the national, state, county, and city levels to measure the rate of influenza infection. These individuals rely on influenza infection rate information to make important decisions during the course of an influenza season driving vaccination campaigns, clinical guidelines, and medical staffing. Web and social media data sources have emerged as attractive alternatives to supplement existing practices. While traditional surveillance methods take 1-2 weeks, and significant labor, to produce an infection estimate in each locale, web and social media data are available in near real-time for a broad range of locations. The objective of this study was to analyze the efficacy of flu surveillance from combining data from the websites Google Flu Trends and HealthTweets at the local level. We considered both emergency department influenza-like illness cases and laboratory-confirmed influenza cases for a single hospital in the City of Baltimore. This was a retrospective observational study comparing estimates of influenza activity of Google Flu Trends and Twitter to actual counts of individuals with laboratory-confirmed influenza, and counts of individuals presenting to the emergency department with influenza-like illness cases. Data were collected from November 20, 2011 through March 16, 2014. Each parameter was evaluated on the municipal, regional, and national scale. We examined the utility of social media data for tracking actual influenza infection at the municipal, state, and national levels. Specifically, we compared the efficacy of Twitter and Google Flu Trends data. We found that municipal-level Twitter data was more effective than regional and national data when tracking actual influenza infection rates in a Baltimore inner-city hospital. When combined, national-level Twitter and Google Flu Trends data outperformed each data source individually. In addition, influenza

    Quantitative evaluation of fungal exposure is often conducted by analysis of the composition of microbes in air samples and calculation of the concentrations afterward. The collecting medium that favors the growth for most saprophytic fungi is considered to be the ideal choice in most circumstances. Currently, the culture medium most frequently adopted in environmental sampling for airborne fungi is MEA (malt extract agar) recommended by the ACGIH for its suitability for most fungal growth. DG18 (dichloran glycerol-18), developed in 1980, is suggested for growth at lower water activity (a(w)=0.95) specifically and is not as commonly used in general studies. This investigation collected airborne viable fungi using a single stage/N6 Andersen impactor with MEA and DG18 agar plates attached simultaneously to the same set of samplers. The sampling locations were at 17 sites within a central air-conditioned hospital. After incubation and morphological identification, concentrations of airborne fungi and bacteria were expressed as CFU/m(3) (colony forming units/m(3)). There are 405 DG18 plates and 378 plates available for statistical analysis. Results show that the airborne fungal concentrations, shown by geometric mean (GM), are higher from the DG18 plates than from the MEA plates. The total fungal concentrations is 68.6 vs 12.94 CFU/m(3), and for Aspergillus spp., the concentration is 1.58 vs 0.72 CFU/m(3); for Penicillium spp., 3.37 vs 0.71; and for yeast, 5.09 vs 0.49 CFU/m(3). In addition, the number of different genera present is greater on the DG18 plates than on the MEA plates, on average, 2.85 types vs 1.72. This study suggests that in a hospital environment with 24-h, central air conditioning, DG18 plates appear to be more effective in collecting more fungal colonies in terms of both quantity and types of genera. Such a finding is presumed to be attributed to the characteristic of DG18 in slowing colony growth so that the dominating genus will not over occupy

    Cerebral palsy (CP) is the leading cause of childhood disability affecting cognitive function and developments in approximately 1.5 to 3 cases per 1000 live births. Based on Ayurvedic therapeutic principles, CP patients were subjected to Abhyanga (massage) with Moorchita Tila Taila (processed sesame oil) and Svedana (fomentation) with Shastikashali Pinda Sveda (fomentation with bolus of drugs prepared with boiled rice). Study group received Mustadi Rajayapana Basti (enema with herbal decoction) and Baladi Yoga (a poly-herbo-mineral formulation), while the placebo group received Godhuma Vati (tablet prepared with wheat powder) and saline water as enema. Treatment with Mustadi Rajayapana Basti and Baladi Yoga improved the activities of daily life by 8.79%, gross motor functions by 19.76%, and fine motor functions 15.05%, and mental functions like memory retention got improved by 15.43%. The placebo group showed an improvement of 0.21% in daily life activities, 2.8% in gross motor, and 2.4% in fine motor functions. Mustadi Rajayapana Basti and Baladi Yoga proved to be more supportive in improving the motor activities and gross behavioral pattern. Further clinical trials are required to evaluate and validate the maximum effect of the combination therapy in a large sample with repetition of the courses for longer duration.

    Cardiac complications in infectious endocarditis (IE) are seen in nearly 50% of cases, and systemic complications may occur. The aim of the present study was to determine the characteristics of inpatients with IE who suffered acute neurologic complications and the factors associated with early mortality. From January 2004 to May 2010, we reviewed clinical and imaging charts of all of the patients diagnosed with IE who presented a deficit suggesting a neurologic complication evaluated with Computed Tomography or Magnetic Resonance within the first week. This was a descriptive and retrolective study. Among 325 cases with IE, we included 35 patients (10.7%) [19 males (54%), mean age 44-years-old]. The most common underlying cardiac disease was rheumatic valvulopathy (n=8, 22.8%). Twenty patients survived (57.2%, group A) and 15 patients died (42.8%, group B) during hospitalization. The main cause of death was septic shock (n=7, 20%). There was no statistical difference among groups concerning clinical presentation, vegetation size, infectious agent and vascular territory. The overall number of lesions was significantly higher in group B (3.1 vs. 1.6, p=0.005) and moderate to severe cerebral edema were more frequent (p=0.09). Sixteen patients (45.7%) (12 in group A and 4 in group B, p=0.05) were treated by cardiac surgery. Only two patients had a favorable outcome with conservative treatment (5.7%). In patients with IE complicated with stroke, the number of lesions observed in neuroimaging examinations and conservative treatment were associated with higher in-hospital mortality.

    Intracranial aneurysms may rupture and are typically associated with high morbidity and mortality, commonly due to vasospasm after rupture. Once the aneurysm ruptures, the patient's cerebral blood flow may be disturbed during the acute phase, affecting cerebral circulation and thus cerebral perfusion prior to the onset of vasospasm. Fisher and Navarro scores are used to predict vasospasm, while World Federation of Neurosurgical Societies (WFNS) scores are used to predict patient outcomes. Several score modifications are available to obtain higher sensitivity and specificity for the prediction of vasospasm development, but these scores are still unsuccessful. Alternatively, cerebral CT perfusion scan (CTP) is a non-invasive method for measuring cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) in regions of interests (ROI) to obtain the cerebral perfusion status as well as detecting vasospasm. A total of 30 patients' data with clipped anterior circulation intracranial aneurysms admitted to the hospital between 1 January 2013 and 30 June 2014, were collected from the hospital's electronic database. The data collected included patients' admissions demographic profiles, Fisher, Navarro and WFNS scores; and their immediate pre- and post-operative CTP parameters. This study found a significant increase in post-operative MTT (pre- and post-operative MTT) were 9.75 (SD = 1.31) and 10.44 (SD = 1.56) respectively, (P < 0.001)) as well as a significant reduction in post-operative CBF (pre- and post-operative mean CBF were 195.29 (SD = 24.92) and 179.49 (SD = 31.17) respectively (P < 0.001)). There were no significant differences in CBV. There were no significant correlations between the pre- and post-operative CTP parameters and Fisher, Navarro or WFNS scores. Despite the interest in using Fisher, Navarro and WFNS scores to predict vasospasm and patient outcomes for ruptured intracranial aneurysms, this study found no significant correlations

    Iodinated x-ray contrast media are unmetabolized and almost completely with the urine in 24 hours emitted in the wastewater after their application by human being. These very polar, hydrophilic and hardly biodegradable substances have already been detected in the water cycle. The objective of this R&D project is the collection of the x-ray contrast media already at the source in the hospital and so the avoidance of an emission in the water cycle. Three concepts have been developed in the scope of this R&D project: a centralized collection concept with a no-mix toilet in the radiology unit, a decentralized collection concept featuring a no-mix toilet for every of the ward and another decentralized collection concept with mobile urine containers for the wards. The evaluation of the collection concepts has taken systematically into consideration costs, acceptance and a value benefit analysis. The feasibility study has shown that a separated collection of iodinated x-ray contrast media in hospitals is possible through the implementation of a decentralized urine collection concept using mobile urine containers. This decentralised collection concept was tested in each case on one main focus ward of two representative German hospitals for 20 weeks. In both wards of the hospitals around 60% of patients with an examination of x-ray contrast media took part in the voluntary urine collection. The AOX arose from the iodinated x-ray contrast media in the collected urine. The averaged measured AOI concentration in the patient's urine was 18 g/l. The total costs, formed by the costs for staff, material and disposal, were estimated at 10 euro per patient, 7 euro per litre urine and approximate 380 euro per kilogramme iodine for the separated urine collection in hospitals. The main part of the total costs is formed by the costs for staff with around 80%. This R&D project has shown that the separated collection of the patients' urine with a simple and decentralised collection

    Cerebral malaria is the most severe pathology caused by the malaria parasite, Plasmodium falciparum. The pathogenic mechanisms leading to cerebral malaria are still poorly defined as studies have been hampered by limited accessibility to human tissues. Nevertheless, histopathology of post-mortem human tissues and mouse models of cerebral malaria have indicated involvement of the blood-brain barrier in cerebral malaria. In contrast to viruses and bacteria, malaria parasites do not infiltrate and infect the brain parenchyma. Instead, rupture of the blood-brain barrier occurs and may lead to hemorrhages resulting in neurological alterations. Here, we review the most recent findings from human studies and mouse models on the interactions of malaria parasites and the blood-brain barrier, shedding light on the pathogenesis of cerebral malaria, which may provide directions for possible interventions.

    Endothelial dysfunction is not only an early stage of atherosclerosis, but also involved in the pathogenesis of cerebral small-vessel diseases. Patients with cerebral microbleeds (CMBs) may have arteriolosclerosis as well as systemic atherosclerosis. However, little is known about the associations among CMBs, atherosclerosis of cerebral large arteries, and endothelial function. Our study aimed to investigate the relationships among them. This was a cross-sectional study. Ninety patients hospitalized in Peking University First Hospital with acute ischemic stroke were enrolled consecutively between November 1, 2007 and January 31, 2008. All subjects underwent transcranial Doppler and carotid color duplex ultrasonography to record the intima-media thickness (IMT) of common carotid artery, carotid plaque, and cerebral artery stenosis. Brain magnetic resonance imaging (MRI) routine sequences and gradient recall-echo T2(*)-weighted imaging were performed to count CMBs with clinical data blindness. Endothelial function was evaluated using flow-mediated dilation (FMD) and nitroglycerin-mediated dilation (NMD) of the brachial artery. FMD and NMD were examined by an experienced vascular sonographer using a high-resolution ultrasound. Thirty cases (33.3%) had CMBs with counts ranging from 1 to 30. Both FMD ((9.9 ± 4.8)% vs. (15. 2 ± 7.4)%, P = 0.001) and NMD ((13.7 ± 6.1)% vs. (19.0 ± 7.4)%, P = 0.001) were significantly decreased in CMB-positive patients than in CMB-negative patients. No significant relationships were demonstrated between CMBs and intracranial and/or extracranial artery stenosis. The frequencies of CMBs in patients with IMT≥1.0 mm, carotid plaque, and extracranial artery stenosis were 37.5%, 39.4%, and 47.6% respectively, with no significant difference, but much higher than in patients with IMT <1.0 mm (5%, P < 0.05). In Logistic regression analysis, impaired FMD (OR = 5.783, 95% CI 1.652-6.718, P = 0.007) and high pulse pressure (OR = 6.228, 95% CI 1

    The first case of cerebral paragonimiasis was reported by Otani in Japan in 1887. This was nine years after Kerbert's discovery of the fluke in the lungs of Bengal tigers and seven years after a human pulmonary infection by the fluke was demonstrated by Baelz and Manson. The first case was a 26-year-old man who had been suffering from cough and hemosputum for one year. The patient developed convulsive seizures with subsequent coma and died. The postmortem examination showed cystic lesions in the right frontal and occipital lobes. An adult fluke was found in the occipital lesion and another was seen in a gross specimen of normal brain tissue around the affected occipital lobe. Two years after Otani's discovery, at autopsy a 29-year-old man with a history of Jacksonian seizure was reported as having cerebral paragonimiasis. Some time later, however, it was confirmed that the case was actually cerebral schistosomiasis japonica. Subsequently, cases of cerebral paragonimiasis were reported. However, the majority of these cases were not confirmed histologically. It was pointed out that some of these early cases were probably not Paragonimus infection. After World War II, reviews as well as case reports were published. Recently, investigations have been reported from Korea, with a clinicla study on 62 cases of cerebral paragonimiasis seen at the Neurology Department of the National Medical Center, Seoul, between 1958 and 1964. In 1971 Higashi described a statistical study on 105 cases of cerebral paragonimiasis that had been treated surgically in Japan.

    The release of hospital wastewater into the urban sewer networks contributes to the general contamination of aquatic media by pharmaceutical residues. These residues include bio-accumulative pharmaceuticals that lead to increased risk for ecosystems because they can concentrate in organisms and food chains, and therefore reach toxic levels. In order to assess the ecotoxicological risks linked to this particular category of residues, we have developed a specific method, by combining a theoretical calculation of pollutant concentrations in organisms to estimate Body Residue (BR), and ecotoxicity biomarkers in fish cell lines, enabling the calculation of a Critical Body Residue (CBR). This method finally results in the calculation of a specific risk quotient (Qb=BR/CBR), characterizing the risk linked to this type of pollutant. This method was applied to mitotane, a bio-accumulative pharmaceutical typically found in hospital wastewater, in the framework of an exposure scenario corresponding to the discharge of all the hospital wastewaters into the Rhone River which flows through the city of Lyon, France. This approach leads to risk quotients (Qb and Qbg) much higher than those found with the classical approach, i.e. Q=PEC/PNEC (Predictive Environmental Concentration/Predictive Non Effect Concentration)=0.0006. This difference in the appreciation of risk is important when using cytotoxicity as the criterion for measuring the toxicity of mitotane (Qb=0.056) and it is even greater when the criterion used is genotoxicity (Qbg=6.8). This study must be now consolidated by taking the biomagnification of the pharmaceuticals into consideration.

    Objectives To evaluate survival curves (Kaplan-Meier) as a means of identifying areas in the clinical pathway amenable to quality improvement. Design Observational before–after study. Setting In Norway, annual public reporting of nationwide 30-day in-and-out-of-hospital mortality (30D) for three medical conditions started in 2011: first time acute myocardial infarction (AMI), stroke and hip fracture; reported for 2009. 12 of 61 hospitals had statistically significant lower/higher mortality compared with the hospital mean. Participants Three hospitals with significantly higher mortality requested detailed analyses for quality improvement purposes: Telemark Hospital Trust Skien (AMI and stroke), Østfold Hospital Trust Fredrikstad (stroke), Innlandet Hospital Trust Gjøvik (hip fracture). Outcome measures Survival curves, crude and risk-adjusted 30D before (2008–2009) and after (2012–2013). Interventions Unadjusted survival curves for the outlier hospitals were compared to curves based on pooled data from the other hospitals for the 30-day period 2008–2009. For patients admitted with AMI (Skien), stroke (Fredrikstad) and hip fracture (Gjøvik), the curves suggested increased mortality from the initial part of the clinical pathway. For stroke (Skien), increased mortality appeared after about 8 days. The curve profiles were thought to reflect suboptimal care in various phases in the clinical pathway. This informed improvement efforts. Results For 2008–2009, hospital-specific curves differed from other hospitals: borderline significant for AMI (p=0.064), highly significant (p≤0.005) for the remainder. After intervention, no difference was found (p>0.188). Before–after comparison of the curves within each hospital revealed a significant change for Fredrikstad (p=0.006). For the three hospitals, crude 30D declined and they were non-outliers for risk-adjusted 30D for 2013. Conclusions Survival curves as a supplement to 30D may be useful for identifying

    Data regarding cerebral venous thrombosis in North Africa are scarce. This study aims to identify the clinical features, risk factors, outcome, and prognosis of cerebral venous thrombosis in Tunisia. Data of 160 patients with radiologically confirmed cerebral venous thrombosis, hospitalized in Mongi Ben Hmida National Institute of Neurology (Tunis, Tunisia), were retrospectively collected and analyzed. The mean age was 37.3 years with a female predominance (83.1%). The mode of onset was subacute in most cases (56.2%). Headache was the most common symptom (71.3%), and focal neurologic symptoms were the main clinical presentation (41.8%). The most common sites of thrombosis were the superior sagittal sinus (65%) and the lateral sinus (60.6%). More than 1 sinus was involved in 114 (71.2%) patients. Parenchymal lesions observed in 85 (53.1%) patients did not correlate with cerebral venous thrombosis extent. Major risk factors were obstetric causes (pregnancy and puerperium) found in 46 (38.6% of women aged <50 years) patients, followed by anemia (28.1%) and congenital or acquired thrombophilia (16.2%). Mortality rate was of 6.6%. Good outcome at 6 months (modified Rankin Scale ≤2) was observed in 105 (87.5%)of 120 patients available for follow-up. Predictors of poor outcome were altered consciousness and elevated plasma C-reactive protein levels. Clinical and radiologic presentation of cerebral venous thrombosis in Tunisia was quite similar to other parts of the world with, however, a particularly high frequency of obstetric causes. Plasma C-reactive protein level should be considered as a prognostic factor in CVT.

    The syndrome of cerebral palsy encompasses a large group of childhood movement and posture disorders. Severity, patterns of motor involvement, and associated impairments such as those of communication, intellectual ability, and epilepsy vary widely. Overall prevalence has remained stable in the past 40 years at 2-3·5 cases per 1000 livebirths, despite changes in antenatal and perinatal care. The few studies available from developing countries suggest prevalence of comparable magnitude. Cerebral palsy is a lifelong disorder; approaches to intervention, whether at an individual or environmental level, should recognise that quality of life and social participation throughout life are what individuals with cerebral palsy seek, not improved physical function for its own sake. In the past few years, the cerebral palsy community has learned that the evidence of benefit for the numerous drugs, surgery, and therapies used over previous decades is weak. Improved understanding of the role of multiple gestation in pathogenesis, of gene environment interaction, and how to influence brain plasticity could yield significant advances in treatment of the disorder. Reduction in the prevalence of post-neonatal cerebral palsy, especially in developing countries, should be possible through improved nutrition, infection control, and accident prevention.

    This work analyses the presence of twenty-five pharmaceutical compounds belonging to seven different therapeutic groups and one iodinated contrast media (ICM) in a Spanish medium-size hospital located in the Valencia Region. Analysis of the target compounds in the hospital wastewater was performed by means of solid phase extraction (SPE) followed by liquid chromatography-tandem mass spectrometry analysis (HPLC-MS/MS). A screening level risk assessment combining the measured environmental concentrations (MECs) with dose-response data based on Predicted No Effect Concentration (PNEC) was also applied to estimate Hazard Quotients (HQs) for the compounds investigated. Additionally, the environmental hazard associated to the various compounds measured was assessed through the calculation of the Persistence, Bioaccumulation and Toxicity (PBT) Index, which categorizes compounds according to their environmentally damaging characteristics. The results of the study showed the presence of twenty-four out of the twenty-six compounds analysed at individual concentrations ranging from 5 ng L(-1) to 2 mg L(-1). The highest concentrations corresponded to the ICM iomeprol, found at levels between 424 and 2093 μg L(-1), the analgesic acetaminophen (15-44 μg L(-1)), the diuretic (DIU) furosemide (6-15 μg L(-1)), and the antibiotics (ABIs) ofloxacin and trimethoprim (2-5 μg L(-1)). The lowest levels corresponded to the anti-inflammatory propyphenazone, found at concentrations between 5 and 44 ng L(-1). Differences in terms of concentrations of the analysed compounds have been observed in all the therapeutic groups when comparing the results obtained in this and other recent studies carried out in hospitals with different characteristics from different geographical areas and in different seasons. The screening level risk assessment performed in raw water from the hospital effluent showed that the analgesics and anti-inflammatories (AAFs) acetaminophen, diclofenac, ibuprofen and

    Carotid intima-media thickness (CIMT) and apolipoproteins have been found as a risk factor for ischemic stroke The objective was to study the carotid intima-media thickness, apolipoproteins, and their relation in patients of ischemic stroke in central rural India. A cross-sectional study was performed in a rural hospital in central India. In all patients of ischemic stroke proven by computerized tomography (CT), CIMT, apolipoprotein A-I (ApoA-I), and apolipoprotein B(ApoB) were measured. We used Student's t-test to compare means, a chi-square test to compare proportions, and a Mann-Whitney test to compare medians. A P value <0.05 was considered significant. The mean age of our study population (N=106) was 61 years. The mean CIMT was 0.83 mm ranging from a minimum of 0.45 mm to a maximum of 1.096 mm. Mean CIMT was significantly higher than expected 0.67 values, which was calculated according to the age of the study population. The association of decreased ApoA-I < 100 mg/dl and increased ApoB > 90 mg/dl with CIMT > 0.7 mm was statistically significant with P<0.001. The CIMT in computerized tomography-proven ischemic stroke was significantly higher than expected for the age of the study population. The relation of decreased ApoA-I and increased ApoB with CIMT > 0.7 mm was also statistically significant.

  15. Cerebral Malaria.

    Marsden, P D; Bruce-Chwatt, L J

    1975-01-01

    Cerebral malaria is an acute diffuse encephalopathy associated only with Plasmodium falciparum. It is probably a consequence of the rapid proliferation of the parasites in the body of man in relation to red cell invasion, and results in stagnation of blood flow in cerebralcapillaries with thromobotic occlusion of large numbers of cerebral capillaries. The subsequent cerebral pathology is cerebral infarction with haemorrhage and cerebral oedema. The wide prevalence of P. falciparum in highly endemic areas results in daily challenges to patients from several infected mosquitoes. It is thus important to understand the characteristics of P. falciparum, since this is one of the most important protozoan parasites of man and severe infection from it constitutes one of the few real clinical emergencies in tropical medicine. One of the more important aspects of the practice of medicine in the tropics is to establish a good understanding of the pattern of medical practice in that area. This applies to malaria as well as to other diseases. The neophyte might be somewhat surprised to learn, for example that an experienced colleague who lives in a holoendemic malarious area such as West Africa, sees no cerebral malaria. But the explanation is simple when the doctor concerned has a practice which involves treating adults only. Cerebral malaria is rare in adults, because in highly endemic areas, by the age of 1 year most of the infants in a group under study have already experienced their first falciparum infection. By the time they reach adult life, they have a solid immunity against severe falciparum infections. In fact, "clinical malaria" could occur in such a group under only two circumstances: 1) in pregnancy, a patent infection with P. falciparum might develop, probably due to an IgG drain across the placenta to the foetus;2) in an individual who has constantly taken antimalarials and who may have an immunity at such a low level that when antimalarial therapy is interrupted

    Cerebral malaria may be the most common non-traumatic encephalopathy in the world. The pathogenesis is heterogenous and the neurological complications are often part of a multisystem dysfunction. The clinical presentation and pathophysiology differs between adults and children. Recent studies have elucidated the molecular mechanisms of pathogenesis and raised possible interventions. Antimalarial drugs, however, remain the only intervention that unequivocally affects outcome, although increasing resistance to the established antimalarial drugs is of grave concern. Artemisinin derivatives have made an impact on treatment, but other drugs may be required. With appropriate antimalarial drugs, the prognosis of cerebral malaria often depends on the management of other complications—for example, renal failure and acidosis. Neurological sequelae are increasingly recognised, but further research on the pathogenesis of coma and neurological damage is required to develop other ancillary treatments.

    Case 1. A seven-year-old boy was admitted to our hospital shortly after developing right hemiplegia and motor aphasia during rope-jumping play. Neither cervical trauma nor signs of cervical and pharyngeal inflammation were present. The physical examination was negative. The carotid angiogram on the day of admission gave poor visualization of the middle cerebral artery group, although the computerized tomographic finding was not remarkable. His neurological status gradually got better, while the routine laboratory studies gave only a slight increase of ESR (26 mm/hour) and positive CRP(I+). There were no particular findings of CSF from lumbar tap or of serological studies. The second computerized tomographic scan 42 hours after clinical onset showed a wide low dense area with obscure margin in the left parieto-temporal region, which was enhanced variously with intravenous contrast media. In about ten days his clinical state was remarkably improved. The second carotid angiogram one month after admission showed a poor filling of the middle cerebral artery territory and beaded appearance of the artery. The patient was discharged on the 46th day with a minimum right hemiparesis. Case 2. A ten-year-old boy was admitted with complaint of right hemiparesis and motor aphasia developing at night. The physical examination was negative. The laboratory studies were also negative. The computerized tomographic scan five days after onset showed a low dense area in size of 2 x 1.5 x 2 cm in the region of the left Nucleus lentiformis. No enhancement effect was seen. The left carotid angiogram on the same day revealed stenotic lesions at the M1 and the posterior temporal artery.(ABSTRACT TRUNCATED AT 250 WORDS)

    The term cerebral palsy (CP), is used for a great number of clinical neurological syndromes. The syndromes are characterized by having a common cause, motor defects. It is important, because they can cause a brain damage by presenting motor defects and some associated deficiencies, such as mental deficiency, epilepsy, language and visual defects and pseudobulbar paralysis, with the non-evolving fact. Some authors prefer using terms such as "non-evolving encephalopathies". In the treatment the utility of prevention programs of early stimulation and special rehabilitation methods, and treatment of associated deficiencies such as epilepsy, mental deficiency, language, audition and visual problems, and the attention deficit improve the prognosis in an important way. The prognosis depends on the severity of the disease and the associated manifestations.

    We report a case of cerebral hemorrhagic infarction after radiation for pituitary adenoma. A 55-year-old woman was hospitalized to check for aldosteronism, post-operative pituitary function, and recurrence of thyroid cancer. She had short-term memory disturbance beginning two months prior to admission. Brain MRI showed a T1 and T2 high intensity lesion of her left anterolateral thalamus. Brain MRA revealed a narrowing in her left middle cerebral artery. The abnormal brain lesion was diagnosed as cerebral hemorrhagic infarction. She had received radiation therapy for pituitary adenoma 20 years earlier. It was considered that her cerebral hemorrhagic infarction was caused by radiation therapy.

    INTRODUCTION Chorioamnionitis is a risk factor for cerebral palsy. The relationship between extra-amniotic infections and cerebral palsy is less well studied. We examined maternal intra- and extra-amniotic infections and risk of cerebral palsy in the child. METHODS Among a retrospective cohort of six million Californian births, 1991–2001, we analyzed administrative maternal and newborn hospital discharge abstracts linked to records of all children receiving services for cerebral palsy at the California Department of Developmental Services. We identified maternal hospital diagnoses of intra-amniotic (chorioamnionitis) and extra-amniotic (other genitourinary and respiratory) infections occurring up to twelve months before delivery. Using multivariable logistic regression, we determined the independent association between maternal infections and cerebral palsy, adjusting for infant sex, maternal age, race, education, socioeconomic status, and obesity. RESULTS 5.5% of mothers had a hospital discharge diagnosis of at least one of the following: chorioamnionitis (2.0%), other genitourinary (3.1%), and respiratory infection (0.6%). An infection diagnosis was more common in mothers of the 8,473 infants with cerebral palsy than in mothers of unaffected children (13.7% vs. 5.5%, P<0.001). All three types of maternal infections (chorioamnionitis, OR 3.1, 95% CI 2.9–3.4; other genitourinary infection, OR 1.4, 95% CI 1.3–1.6; and respiratory infection, OR 1.9, 95% CI 1.5–2.2) were associated with cerebral palsy in multivariable analyses. Maternal extra-amniotic infections, whether diagnosed during prenatal or birth hospitalizations, conferred an increased risk of cerebral palsy. CONCLUSIONS Maternal extra-amniotic infections diagnosed in the hospital during pregnancy are associated with a modestly increased risk of cerebral palsy in the child. PMID:26857522

    Background. Nontraumatic cerebral air embolism cases are rare. We report a case of an air embolism resulting in cerebral infarction related to angioinvasive cavitary aspergillosis. To our knowledge, there have been no previous reports associating these two conditions together. Case Presentation. A 32-year-old female was admitted for treatment of acute lymphoblastic leukemia (ALL). Her hospital course was complicated by pulmonary aspergillosis. On hospital day 55, she acutely developed severe global aphasia with right hemiplegia. A CT and CT-angiogram of her head and neck were obtained demonstrating intravascular air emboli within the left middle cerebral artery (MCA) branches. She was emergently taken for hyperbaric oxygen therapy (HBOT). Evaluation for origin of the air embolus revealed an air focus along the left lower pulmonary vein. Over the course of 48 hours, her symptoms significantly improved. Conclusion. This unique case details an immunocompromised patient with pulmonary aspergillosis cavitary lesions that invaded into a pulmonary vein and caused a cerebral air embolism. With cerebral air embolisms, the acute treatment option differs from the typical ischemic stroke pathway and the provider should consider emergent HBOT. This case highlights the importance of considering atypical causes of acute ischemic stroke.

    2016-01-01

    Cerebral vasospasm associated with hyperthyroidism has not been reported to cause cerebral infarction. The case reported here is therefore the first of cerebral infarction co-existing with severe vasospasm and hyperthyroidism. A 30-year-old woman was transferred to our hospital in a stuporous state with right hemiparesis. At first, she complained of headache and dizziness. However, she had no neurological deficits or radiological abnormalities. She was diagnosed with hyperthyroidism 2 months ago, but she had discontinued the antithyroid medication herself three days ago. Magnetic resonance imaging and angiography showed cerebral infarction with severe vasospasm. Thus, chemical angioplasty using verapamil was performed two times, and antithyroid medication was administered. Follow-up angiography performed at 6 weeks demonstrated complete recovery of the vasospasm. At the 2-year clinical follow-up, she was alert with mild weakness and cortical blindness. Hyperthyroidism may influence cerebral vascular hemodynamics. Therefore, a sudden increase in the thyroid hormone levels in the clinical setting should be avoided to prevent cerebrovascular accidents. When neurological deterioration is noticed without primary cerebral parenchyma lesions, evaluation of thyroid function may be required before the symptoms occur. PMID:28184350

    Studies have shown maintaining good cerebral perfusion during Cardiac Surgeries is very important in terms of patient outcomes and reducing the hospital stay, which may have its financial and clinical implications. The aim of this review study was to determine the effectiveness of Cerebral Oximetry (Transcranial Near-Infrared Spectroscopy-NIRS to monitor cerebral oxygenation) for Cardiac Surgery and to propose a possible concluding remark about its potential applications, overall clinical value and whether to keep using it or not. Medical database and archives including Pubmed, Embase, index medicus, index copernicus and Medline were searched. Different papers were looked upon and each had an argument, scientific evidence and background. Fifteen research papers were selected and brought under review after carefully consideration. The papers were carefully reviewed and findings were given in favour of not using NIRS technique for Cerebral Oximetry in Cardiac Surgery. This can rightly be concluded from this study that NIRS Cerebral Oximetry does not carry the clinical significance and relevance which was previously thought. The subject under observation needs further studies and research to evaluate the effectiveness of the Cerebral Oximetry Use for Cardiac Surgery.

    2004-05-01

    We have investigated establishment of collateral circulation in patients with cerebral circulation disorder. Thirty angiograms of patients treated at Neurological Department of Hospital Centre in Sarajevo suffering from arteriae cerebri mediae occlusion were used for this study. Cerebral anastomoses that included connections between arteriae cerebri anterior and arteriae cerebri mediae over leptomeningeal anastomoses occurred in some patients suffering from occlusion of this arteriae. It was concluded that the majority of anastomoses existed between big leptomeningeal branches of postcommunicant segment of a. cerebri anterior and branches of cerebri mediae. These collaterals are of great significance as their functional ability is sometimes of a high degree in cases of occlusion of one or the other artery. It can be concluded that anastomosing of the blood vessels increases their volume in the whole and therefore more blood can be provided, although physiological factors should not be neglected, as functional effectiveness of collateral circulation in postocclusive states depends also on the state of the whole cerebrovascular system, then on the speed of creation of occlusion (thrombosis or embolism), systemic arterial pressure, volume and viscosity of the blood.

    acute otitis media is a frequent disease in the pediatric age. About 2 % of all cases develop intracranial complications such as meningitis. The cerebral infarction originates meningitis and usually occurs in the venous system. The presence of a cerebral artery infarction secondary to acute otitis media is a rare cause described in the literature. a girl of 12 months who presented a febrile syndrome due to acute otitis media and mental confusion. On physical examination, she appeared sleepy with anisocoria, mydriasis in the right eye and left hemiparesis. The computed tomography examination showed extensive cerebral artery infarction. The patient's parents refused the proposed surgical treatment and the girl died 48 hours later. regardless of the current technological advances, the clinical prognosis of cerebral infarction associated with acute otitis media is bad. The focused neurological signs and progressive clinical deterioration should raise suspicion that antimicrobial therapy is not effective.

    Drinking coffee causes caffeine-induced physiological alterations such as increases in arterial blood pressure, sympathetic nerve activity, cerebral vasoconstriction, etc., and these physiological alterations may be associated with a reduced risk of cerebral vascular disease. However, the effect of coffee drinking on dynamic cerebral blood flow (CBF) regulation remains unclear. The aim of this study was to test our hypothesis that coffee drinking enhances dynamic cerebral autoregulation. Twelve healthy young subjects participated in the present study. After a 5 min baseline measurement in a semi-recumbent position on the hospital bed, each subject drank water (CON) as a placebo condition or coffee beverage (Coffee INT). Arterial blood pressure and middle cerebral artery blood velocity (MCAv) were measured continuously throughout the experiment. At 30 min after the intake of either water or coffee, dynamic cerebral autoregulation was examined using a thigh cuffs occlusion and release technique. Each condition was randomly performed on a different day. Under Coffee INT condition, mean arterial blood pressure was increased (P = 0.01) and mean MCAv was decreased (P = 0.01) from the baseline. The rate of regulation (RoR), as an index of dynamic cerebral autoregulation, during coffee condition was significantly higher than that during CON (P = 0.0009). The findings of the present study suggest that coffee drinking augments dynamic CBF regulation with cerebral vasoconstriction. This phenomenon may be associated with a reduction in the risk of cerebral vascular disease.

    Cerebral actinomycosis is rare and difficult to diagnose. We report a case of a 45-year-old man hospitalized for seizures associated with fever and left hemiparesis. The white cell count and C-reactive protein were elevated. HIV serology was negative. Blood cultures remained sterile. The CT scan revealed hyperdense nodular lesions in the occipital area, with annular contrast uptake and peripheral edema causing a mass effect, suggestive of brain metastasis. The pathology examination of a surgical specimen disclosed cerebral actinomycosis. A dental origin of the infection was suspected. Hemiparesis remained after a 12-month antibiotic regimen associated with dental care and short-term corticosteroid therapy. Actinomycosis should be discussed as a possible diagnosis for all cerebral lesions, particularly in patients with a potential dental infection. Histology is required for positive diagnosis. Antibiotic therapy alone is generally sufficient; surgery is often performed for diagnostic purposes. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

    Reversible cerebral vasoconstriction syndrome (RCVS) is increasingly recognized. The condition is characterized by multifocal vasoconstriction lesions in cerebral arteries. Headache is the central symptom, with an acute onset and paroxysmal occurrence. Some of the patients develop intracranial hemorrhage, ischemic disturbance of the cerebral circulation, hypertensive encephalopathy (PRES) or epileptic seizures as complications. The disease is most common in middle-aged women. Most patients have an underlying predisposing factor, most commonly vasoactive medications, drugs or puerperium. There is no evidence-based practice.

    2012-01-01

    HMG-CoA reductase inhibitors (statins) are associated with improved stroke outcome. This observation has been attributed in part to the palliative effect of statins on cerebral hemodynamics and cerebral autoregulation (CA), which are mediated mainly through the upregulation of endothelium nitric oxide synthase (eNOS). Several animal studies indicate that statin pretreatment enhances cerebral blood flow after ischemic stroke, although this finding is not further supported in clinical settings. Cerebral vasomotor reactivity, however, is significantly improved after long-term statin administration in most patients with severe small vessel disease, aneurysmal subarachnoid hemorrhage, or impaired baseline CA.

    We encountered a case of nontraumatic arterial dissection of the anterior cerebral artery (ACA) which exhibited cerebral infarction and subarachnoid hemorrhage (SAH) simultaneously, and whose symptoms were improved by conservative treatment. A 55-year-old female presenting with headache and weakness in her left leg was admitted to our hospital. CT scans on admission revealed SAH in the interhemispheric fissure and surface of the right frontal lobe, but CT scans at 3 days after onset demonstrated cerebral infarction in the medial part of the right frontal lobe. Cerebral angiography on day 6 disclosed an aneurysmal dilatation and narrowing at the right A2-A3 segment. We continued conservative therapy including blood pressure control, since there was no symptomatic deterioration. The aneurysmal dilatation disappeared and the weakness of the left leg also improved. This case indicates that conservative treatment could be an option for the management of nontraumatic arterial dissection of the ACA with simultaneous cerebral infarction and SAH.

The patients particularly at risk were those who were overtly unconscious and those with any combination of impaired consciousness, dense hemiplegia, and failure of conjugate ocular gaze towards the side of the limb weakness. Necropsy evidence suggested that these signs usually indicate infarction of the whole of one middle cerebral artery territory which is often secondary to internal carotid artery occlusion and commonly produces fatal cerebral oedema.

    Cerebral vasculopathy have been described in Fabry disease, in which altered cerebral blood flow, vascular remodelling or impairment of endothelial function could be involved. Our study aims to evaluate these three possibilities in a group of Fabry patients, and compare it to healthy controls. Cerebral hemodynamics, vascular remodelling and systemic endothelial function were investigated in 10 Fabry patients and compared to data from 17 healthy controls. Transcranial Doppler was used to study blood flow velocity of intracranial arteries and cerebral vasomotor reactivity. For the study of vascular remodelling and endothelial function, intima-media thickness of common carotid arteries, flow-mediated dilation in brachial artery and serum levels of soluble VCAM-1, TNF-α, high-sensitive CRP and IL-6 were measured. Differences between groups were evaluated using appropriate tests. No relevant differences were observed in cerebral hemodynamic parameters, intima-media thickness or flow-mediated dilation. There was a trend for low serum levels of IL-6 and high serum levels of TNF-α and high-sensitive CRP in Fabry patients; plasma concentrations of soluble VCAM-1 were significantly higher in Fabry disease patients than in healthy volunteers (p = 0.02). In our sample, we did not find relevant alterations of cerebral hemodynamics in Fabry disease patients. Increased levels of plasmatic endothelial biomarkers seem to be the most important feature indicative of possible vascular dysfunction in Fabry disease patients.

    Social media use has increased both in the general public and in the surgical profession. A variety of social media platforms have been used, with Twitter being one of the most common and interactive platforms. Common uses by surgeons and scientists for social media include dissemination of information, information exchange, education, research recruitment, community consultation for clinical trials, and hospital or surgeon ratings. As social media use increases, a new language as well as metrics has been developed to track impact and reach of research incorporating social media platforms. All surgeons should be encouraged to familiarize themselves with social media, regardless of whether or not they choose to actively engage in it.

    Cerebral salt-wasting syndrome is a condition featuring hyponatremia and dehydration caused by head injury, operation on the brain, subarachnoid hemorrhage, brain tumor and so on. However, there are a few reports of cerebral salt-wasting syndrome caused by cerebral infarction. We describe a patient with cerebral infarction who developed cerebral salt-wasting syndrome in the course of hemorrhagic transformation. A 79-year-old Japanese woman with hypertension and arrhythmia was admitted to our hospital for mild consciousness disturbance, conjugate deviation to right, left unilateral spatial neglect and left hemiparesis. Magnetic resonance imaging revealed a broad ischemic change in right middle cerebral arterial territory. She was diagnosed as cardiogenic cerebral embolism because atrial fibrillation was detected on electrocardiogram on admission. She showed hyponatremia accompanied by polyuria complicated at the same time with the development of hemorrhagic transformation on day 14 after admission. Based on her hypovolemic hyponatremia, she was evaluated as not having syndrome of inappropriate secretion of antidiuretic hormone but cerebral salt-wasting syndrome. She fortunately recovered with proper fluid replacement and electrolyte management. This is a rare case of cerebral infarction and cerebral salt-wasting syndrome in the course of hemorrhagic transformation. It may be difficult to distinguish cerebral salt-wasting syndrome from syndrome of inappropriate antidiuretic hormone, however, an accurate assessment is needed to reveal the diagnosis of cerebral salt-wasting syndrome because the recommended fluid management is opposite in the two conditions.

    Patients infected with the human immunodeficiency virus (HIV) appear to have a high risk of ischaemic cerebral events. We observed two cases of cerebral infarction in patients with acquired immune deficiency syndrome (AIDS). In the first case, a 38-year-old homosexual with no cardiovascular risk other than smoking presented with rapidly progressive hemiparesia. Brain CT-scan visualized two infarcts in the territory of the right sylvian artery and the arteriography an occlusion of the internal carotid artery. In the second, a 37-year-old homosexual, hospitalization was required for a left-sided pure sensitive epilepsy seizure. There was no cardiovascular risk other than smoking. Magnetic resonance imaging showed parietal ischaemia and thrombus in the left atrium without atrial hypertrophy was seen at transoesophageal echocardiography. In both cases, there was no evidence of endocarditis, dissection of the neck vessels or disseminated intravascular coagulation nor of associated viral or bacterial infectious complication of AIDS. Angiographic findings eliminated cerebral vascularitis. Among the perturbed haemostasis factors previously reported in HIV+ patients, we observed free proteins S deficiency (68 and 43%) and heparin cofactor II deficiency (54 and 40%). Serum albumin was 33 and 32 g/l respectively. Outcome was favourable in both cases with anticoagulant therapy. These coagulation anomalies would not appear sufficient to explain cerebral infarction. Other mechanisms including immune complexed deposition, direct HIV toxicity for endothelial cells or the effect of cytokines on smooth muscles fibres and fibroblasts are probably more important causal factors.

    Cerebral palsy is a chronic childhood disorder that can have diverse etiologies. Injury to the developing brain that occurs either in utero or soon after birth can result in the motor, sensory, and cognitive deficits seen in cerebral palsy. Although the etiologies for cerebral palsy are variable, neuroinflammation plays a key role in the pathophysiology of the brain injury irrespective of the etiology. Currently, there is no effective cure for cerebral palsy. Nanomedicine offers a new frontier in the development of therapies for prevention and treatment of brain injury resulting in cerebral palsy. Nanomaterials such as dendrimers provide opportunities for the targeted delivery of multiple drugs that can mitigate several pathways involved in injury and can be delivered specifically to the cells that are responsible for neuroinflammation and injury. These materials also offer the opportunity to deliver agents that would promote repair and regeneration in the brain, resulting not only in attenuation of injury, but also enabling normal growth. In this review, the current advances in nanotechnology for treatment of brain injury are discussed with specific relevance to cerebral palsy. Future directions that would facilitate clinical translation in neonates and children are also addressed. PMID:24204146

  6. Cerebral monitoring during carotid endarterectomy by transcranial Doppler ultrasonography

    PubMed Central

    2017-01-01

    Purpose To evaluate the efficacy and safety of cerebral monitoring by transcranial Doppler ultrasonography (TCD) for the detection of cerebral ischemia during carotid endarterectomy (CEA). Methods From August 2004 to December 2013, 159 CEAs were performed in a tertiary hospital. All procedures were performed under general anesthesia. Intraoperative TCD was routinely used to detect cerebral ischemia. Of the 159 patients, 102 patients were included in this study, excluding 27 patients who had a poor transtemporal isonation window and 30 patients who used additional cerebral monitoring systems such as electroencephalography or somatosensory evoked potentials. When mean flow velocity in the ipsilateral middle cerebral artery decreased by >50% versus baseline during carotid clamping carotid shunting was selectively performed. The carotid shunt rate and incidence of perioperative (<30 days) stroke or death were investigated by reviewing medical records. Results Carotid shunting was performed in 31 of the 102 patients (30%). Perioperative stroke occurred in 2 patients (2%); a minor ischemic stroke caused by embolism in one and an intracerebral hemorrhage in the other. Perioperative death developed in the latter patient. Conclusion TCD is a safe cerebral monitoring tool to detect cerebral ischemia during CEA. It can reduce use of carotid shunt. PMID:28203558

    This study aimed to evaluate cerebral magnetic resonance imaging (MRI) scans of children with prenatal drug exposure in a clinical context. A hospital-based cohort of 10- to 14-year-old children, prenatally exposed to alcohol, opioids, and polysubstances, and a group of sex- and age-matched controls were examined with cerebral MRI. Scans obtained from 34 exposed children and 40 controls were scored based on the presence and degree of pathology by an experienced pediatric neuroradiologist blinded to the participants' background. Overall visual detectable MRI pathology was found in 35% of the exposed children and 33% of the controls (odds ratio = 1.08; 95% confidence interval = 0.36-3.25). No specific imaging pattern following prenatal drug exposure was seen by the means of simple visual analysis of cerebral MRI scans. Although cerebral MRI is feasible, it is probably of limited value in the clinical assessment of children with prenatal drug exposure.

    2012-04-01

    Both news media and entertainment fiction may lead to short-term and enduring fright reactions. Even TV programs, movies and news made for children may trigger fear. Preoperational children (3 to 7 years of age) are most afraid of fantasy characters, transformations and interpersonal violence. Operational children (8 to 11 years) are more afraid of abstract ideas and imagined implications regarding their own risk. Pediatricians must include media in their history taking and beware of ensuing fear, phobias, sleep and behavior problems. Parents can play a vital role in preventing exposure to or mediating the effects of frightening media. Hospitals must have a pediatric media exposure policy. Media use can have immediate and enduring fear effects that affect many children and that are far from trivial.

    Some pregnant women avoid labor epidural analgesia because of their concerns about risk of cerebral palsy in children. Although it is believed that labor epidural does not contribute to cerebral palsy, to our knowledge no study has been published to specifically address this concern. We carried out a retrospective case-control study to investigate whether labor epidural analgesia is associated with cerebral palsy in children. This study used data that were collected and entered into the Geisinger electronic health records between January 2004 and January 2013. During this period, 20,929 children were born at Geisinger hospitals. Among them, 50 children were diagnosed with cerebral palsy, and 20 of those were born vaginally. Each of these 20 cerebral palsy children was matched with up to 5 non-cerebral palsy children born at the same hospitals in the same timeframe using propensity scoring methods. Analgesia was classified as epidural (including epidural or combined spinal and epidural) or non-epidural. Conditional logistic regression was used to compare the percentages of deliveries with each analgesia type between the cerebral palsy and non-cerebral palsy groups. In the non-cerebral palsy group, the percentage of patients receiving labor epidural analgesia was 72 %, and in the cerebral palsy group the percentage was 45 %. There was no significant difference between non-cerebral palsy and cerebral palsy groups (odds ratio, 0.57; 95 % confidence interval, 0.14-2.24; p = 0.42). We found no association between the use of labor epidural analgesia and the occurrence of cerebral palsy in children.

    For the technological advances in diagnostic and therapeutic procedures, the use of intravenous contrast media in the hospital is more and more frequent. It can produce acute renal failure secondary to its nephrotoxicity known as contrast media nephropathy. This review describes the pathophysiologic mechanisms of contrast media injury, including cytotoxicity caused by hyperosmoloarity of contrast media, the hemodynamic factors and the role of the renin-angiotensin system, prostaglandins, oxygen free radicals, endothelin-1, adenosine, nitric oxide and others. The understanding of this information is of vital importance for the development of prophylactic strategies for contrast media nephropathy.

    Research on the effects of media violence is not well understood by the general public. Despite this fact, there is an overwhelming consensus in the scientific literature about the unhealthy effects of media violence. Meta-analyses show that media-violence viewing consistently is associated with higher levels of antisocial behavior, ranging from the trivial (imitative violence directed against toys) to the serious (criminal violence), with many consequential outcomes in between (acceptance of violence as a solution to problems, increased feelings of hostility, and the apparent delivery of painful stimulation to another person). Desensitization is another well-documented effect of viewing violence, which is observable in reduced arousal and emotional disturbance while witnessing violence, the reduced tendency to intervene in a fight, and less sympathy for the victims of violence. Although there is evidence that youth who are already violent are more likely to seek out violent entertainment, there is strong evidence that the relationship between violence viewing and antisocial behavior is bidirectional. There is growing evidence that media violence also engenders intense fear in children which often lasts days, months, and even years. The media's potential role in solutions to these problems is only beginning to be explored, in investigations examining the uses and effects of movie ratings, television ratings, and the V-chip, and the effects of media literacy programs and public education efforts. Future research should explore important individual differences in responses to media violence and effective ways to intervene in the negative effects.

    American media are the most violent in the world, and American society is now paying a high price in terms of real life violence. Research has confirmed that mass media violence contributes to aggressive behavior, fear, and desensitization of violence. Television, movies, music videos, computer/video games are pervasive media and represent important influences on children and adolescents. Portraying rewards and punishments and showing the consequences of violence are probably the two most essential contextual factors for viewers as they interpret the meaning of what they are viewing on television. Public health efforts have emphasized public education, media literacy campaign for children and parents, and an increased use of technology to prevent access to certain harmful medial materials.

  1. [Cerebral ischemia and histamine].

    PubMed

    Adachi, Naoto

    2002-10-01

    Cerebral ischemia induces excess release of glutamate and an increase in the intracellular Ca2+ concentration, which provoke catastrophic enzymatic processes leading to irreversible neuronal injury. Histamine plays the role of neurotransmitter in the central nervous system, and histaminergic fibers are widely distributed in the brain. In cerebral ischemia, release of histamine from nerve endings has been shown to be enhanced by facilitation of its activity. An inhibition of the histaminergic activity in ischemia aggravates the histologic outcome. In contrast, intracerebroventricular administration of histamine improves the aggravation, whereas blockade of histamine H2 receptors aggravates ischemic injury. Furthermore, H2 blockade enhances ischemic release of glutamate and dopamine. These findings suggest that central histamine provides beneficial effects against ischemic neuronal damage by suppressing release of excitatory neurotransmitters. However, histaminergic H2 action facilitates the permeability of the blood-brain barrier and shows deleterious effects on cerebral edema.

    1962-01-01

    Six patients are described in whom cerebral damage was associated with raised plasma sodium and chloride concentrations and with extremely low urinary outputs of sodium and chloride. The patients were not clinically dehydrated and direct determinations showed that the blood and plasma volumes, the endogenous creatinine clearance, and the urinary output of antidiuretic hormone were normal. For these and other reasons it is concluded that the metabolic picture results not from diminished circulatory volume, water deficiency, sodium deficiency, undetected diabetes insipidus or osmotic diuresis, but from the cerebral damage itself. In these and other cited cases, the cerebral damage was localized chiefly in the frontal lobes, hypothalamus or lower brain-stem, thus suggesting a descending pathway, the relationship of which to the pineal area controlling aldosterone secretion requires clarification.

    Duplicated middle cerebral artery (DMCA) is an anomalous vessel arising from the internal carotid artery. The incidence DMCA is relatively law, and an association between this anomaly and cerebral aneurysms has been documented. There is a controversy whether DMCA may have perforating arteries. This is an important fact to consider in aneurysm surgery. We report the case of a 34-year-old black woman who suffered a subarachnoid hemorrhage and the angiography a left DMCA, and an aneurysm in an inferior branch of the main MCA. The DMCA and the MCA had perforating arteries. The aneurysm was clipped without complications. The observation of perforating arteries in our patient confirms that the DMCA may have perforating arteries. This is very important to be considered in cerebral aneurysms surgery. Moreover, the DMCA may potentially serve as a collateral blood supply to the MCA territory in cases of MCA occlusion.

    Cerebral venous sinus thrombosis (CVST) rarely induces cerebral hemorrhage, and CVST with cerebral hemorrhage during early pregnancy is extremely rare. Upon literature review, we are able to find only one case of CVST with cerebral hemorrhage in early pregnancy. In this paper, we report another case of a 27-year-old patient who developed CVST with cerebral hemorrhage in her fifth week of pregnancy. Although the optimal treatment for this infrequent condition remains controversial, we adopted anticoagulation as the first choice of treatment and obtained favorable results. PMID:25630781

    A computer database system has been built which records all the necessary information on each item of equipment. This includes the name of the Department, the location (building and room number), a description of the asset (manufacturer, model number, serial number). The purchase date and source of funding (e.g., state or charity) are then recorded. The details of the maintenance program (e.g., company contracted, service date, service cost) follow next. Last and of equal importance, there follows one or more pictures of the item of equipment. Any special features can then be identified. These pictures form an integral part of each record in the database. The system runs on a desk-top PC under a networked system.

  6. Social Media in Pediatric Orthopaedics.

    Lander, Sarah T; Sanders, James O; Cook, Peter C; O'Malley, Natasha T

    Internet searches and social media utilization in health care has exploded over the past 5 years, and patients utilize it to gain information on their health conditions and physicians. Social media has the potential to serve as a means for education, communication, and marketing in all health care specialties. Physicians are sometimes reluctant to engage because of concerns of privacy, litigation, and lack of experience with this modality. Many surgical subspecialties have capitalized on social media but no study to date has examined the specific footprint of pediatric orthopaedic surgeons in this realm. We aim to quantify the utilization of individual social media platforms by pediatric orthopaedic surgeons, and identify any differences between private and hospital-based physicians, but also regional differences. Using the Pediatric Orthopaedic Society of North America Member Directory, each active member's social media presence was reviewed through an Internet search. Members were stratified on the basis of practice model and geographic location. Individual Internet searches, social media sites, and number of publications were reviewed for social media presence. Of 987 Pediatric Orthopaedic Society of North America members, 95% had a professional webpage, 14.8% a professional Facebook page, 2.2% a professional Twitter page, 36.8% a LinkedIn profile, 25.8% a ResearchGate profile, 33% at least 1 YouTube. Hospital-based physicians had a lower mean level of utilization of social media compared with their private practice peers, and a higher incidence of Pubmed publications. Private practice physicians had double the social media utilization. Regional differences reveal that practicing Pediatric Orthopaedists in the Northeast had increased utilization of ResearchGate and LinkedIn and the West had the lowest mean social media utilization levels. The rapid expansion of social media usage by patients and their family members is an undeniable force affecting the health

    Forty cases of cerebral abscesses were studied prospectively to establish the microbial agents implicated in these cases. Chronic otitis media (14 patients, 35%), congenital heart disease (five patients, 12.5%),a and meningitis (five patients, 12.5%) were among the important predisposing factors. Streptococcus (14 patients, 35%) was the most common causative pre-isolated, the predominant species being Streptococcus milleri (11 patients, 27.5%). Other organisms isolated included Proteus mirabilis in six patients (15%) and Staphylococcus aureus in five patients (12.5%). Anaerobes (12 patients, 30%), predominantly Bacteroides sp. (eight patients, 20%), played an important role in these cases, the majority of which were isolated in mixed cultures. Gas-liquid chromatographic analysis of pus detected the presence of anaerobes in another 11 cases of cerebral abscess, in which cultures of anaerobes were negative. Therefore, gas-liquid chromotography is useful as an adjunct to conventional bacteriological methods in providing a rapid and sensitive means of detecting anaerobes in pus obtained especially from patients who had received antibiotic therapy prior to hospitalization.

    1989-04-01

    The authors report a case of brain abscess following cerebral infarction. A 73-year-old man was admitted to our clinic with symptoms of right hemiparesis and total aphasia. CT scan revealed abnormal low density area in the left fronto-temporo-parietal region. Cerebral angiography demonstrated occlusion of the left middle cerebral artery at the M1 portion. On the 16th hospital day, an episode of generalized seizure with high fever appeared, and intermittent high fever persisted thereafter. Two months after admission, CT scan revealed several cystic lesions with marked ring enhancement at the site of cerebral infarction, suggesting multiple abscesses. Aspirations of left frontal and parietal abscesses were accomplished and the cultures of the pus disclosed Proteus vulgaris. Due to progressive hydrocephalus, a ventriculoperitoneal shunt was constructed one month later. Repeated CT scans showed a gradual diminution of the abscesses. It is considered that the blood-brain barrier is broken and the local immunological system against bacteria may be weakened when the brain is damaged by ischemia. Brain abscess seems to be developed in such circumstances even under the influence of transient bacteremia which originates in other parts of the body. Therefore the possibility of cerebral abscess should be suspected if patients with cerebral infarction suffer from the symptoms such as fever, neck stiffness or disturbance of consciousness.

    Cerebral complications are well-identified causes of morbidity and mortality in patients with infective endocarditis (IE). Few studies have analysed the impact of brain magnetic resonance imaging (MRI) in IE patients with neurological manifestations. The aims of this study were to assess the MRI contribution to the management of patients with IE neurological manifestations and to compare cerebral CT and MRI findings. Patients with definite or probable IE and neurological manifestations were prospectively enrolled from 2005 to 2008, in a university hospital (Bichat Claude Bernard Hospital, Paris). Clinical and radiological characteristics and echocardiographic findings were systematically recorded. Brain MRI with angiography was performed and compared to available CT scans. The contribution of MRI results to cerebral involvement staging and to therapeutic plans was evaluated. Thirty patients, 37-89 years old, were included. Nineteen suffered from pre-existing heart disease. Blood cultures were positive in 29 cases and the main micro-organisms were streptococci (n = 14) and staphylococci (n = 13). The IE was mainly located on mitral (n = 15) and aortic valves (n = 13). Neurological events were strokes (n = 12), meningitis (n = 5), seizures (n = 1), impaired consciousness (n = 11) and severe headache (n = 1). MRI findings included ischaemic lesions (n = 25), haemorrhagic lesions (n = 2), subarachnoid haemorrhage (n = 5), brain abscess (n = 6), mycotic aneurysm (n = 7), vascular occlusion (n = 3) and cerebral microbleeds (n = 17). In 19/30 cases, neurological manifestations were observed before the diagnosis of IE. MRI was more sensitive than CT scan in detecting both clinically symptomatic cerebral lesions (100 and 81%, respectively) and additional asymptomatic lesions (50 and 23%, respectively). Therapeutic plans were modified according to MRI results in 27% of patients: antibiotherapy regimen modifications in 7% (switch for molecules with high cerebral diffusion

    A clinicopathological analysis of myocardial infarction with an onset of stroke-like symptoms was carried out on 30 autopsy cases at the Tokyo Metropolitan Geriatric Hospital. The cases were classified into four groups according to the types of brain lesions, I: embolism (n = 17), II: thrombosis (n = 9), III: bleeding (n = 2), and IV: no remarkable focal lesion (n = 2). Classification was made based on clinical findings, and pathological features. The characteristic clinical findings were conciousness disturbance, no elevation of blood pressure at the onset of stroke, hemiplegia and shock. However, the typical anginal chest pain was found in only 17% of cases. The underlying diseases and complications were hypertension, atrial fibrillation (Af), disseminated intravascular coagulation (DIC), renal failure, malignant neoplasma, and diabetes mellitus. The incidences of Af, DIC, mural thrombus, non-bacterial thrombotic endocarditis (NBTE) were significantly higher in the group with cerebral embolism than in the group with cerebral thrombosis. The coronary stenotic index was also smaller in the group with cerebral embolism. Therefore, the major etiology of cardio-cerebral apoplexy was a simultaneous embolism to the brain and heart due to Af, NBTE or, DIC.

    The numbers of contrast media (CM)-enhanced examinations are increasing. The annual sale of iodine for CM now represents 60 million CM doses a year world-wide. In spite of improvements in chemical structure, CM are still the third leading cause of hospital-acquired acute renal failure. The definition of contrast nephropathy (CN) is discussed, as well as the mechanisms involved in the pathogenesis. Low osmolar contrast media (LOCM) are less nephrotoxic than high osomolar contrast media (HOCM) and cause fewer osmotoxic side-effects such as pain and heat sensations. The non-ionic dimeric contrast media which are iso-osmolar to plasma (IOCM) cause even fewer haemodynamic side-effects and result in better opacification of the urinary tract than LOCM. The nephrotoxicity of IOCM is low. The risk factors for CN and methods for prevention of CN are discussed.

    Recurrent thunderclap headaches, seizures, strokes, and non-aneurysmal subarachnoid haemorrhage can all reveal reversible cerebral vasoconstriction syndrome. This increasingly recognised syndrome is characterised by severe headaches, with or without other symptoms, and segmental constriction of cerebral arteries that resolves within 3 months. Reversible cerebral vasoconstriction syndrome is supposedly due to a transient disturbance in the control of cerebrovascular tone. More than half the cases occur post partum or after exposure to adrenergic or serotonergic drugs. Manifestations have a uniphasic course, and vary from pure cephalalgic forms to rare catastrophic forms associated with several haemorrhagic and ischaemic strokes, brain oedema, and death. Diagnosis can be hampered by the dynamic nature of clinicoradiological features. Stroke can occur a few days after initial normal imaging, and cerebral vasoconstriction is at a maximum on angiograms 2-3 weeks after clinical onset. The calcium channel blocker nimodipine seems to reduce thunderclap headaches within 48 h of administration, but has no proven effect on haemorrhagic and ischaemic complications.

    Reversible cerebral vasoconstriction syndrome is characterized by severe headaches with or without focal neurologic deficits and/or seizures, and segmental constriction of cerebral arteries that resolves within 3 months. This increasingly recognized syndrome is supposedly due to a transient disturbance in the control of cerebral vascular tone with sympathetic overactivity. It can cause stroke in the young. It affects mainly middle-aged women. More than half the cases occur after exposure to vasoactive substances or during postpartum. The manifestations have a monophasic course, without new clinical symptom after 4 weeks, and range from pure cephalalgic forms with recurrent thunderclap headaches over 1-2 weeks to rare catastrophic forms with multiple hemorrhagic and ischemic strokes, brain edema and death. Diagnosis may be hampered by the dynamic nature of clinicoradiological features. Convexity subarachnoid hemorrhage or stroke may occur a few days after initial normal imaging, and cerebral vasoconstriction is maximal on angiography 2-3 weeks after clinical onset. Symptomatic treatment includes rest and removal of vasoactive substances. Nimodipine has been proposed to reduce thunderclap headaches within 48 hours, but has no proven effect on the hemorrhagic and ischemic complications. © 2014 Elsevier B.V. All rights reserved.

    The cardinal driver of cerebral palsy litigation is electronic fetal monitoring, which has continued unabated for 40 years. Electronic fetal monitoring, however, is based on 19th-century childbirth myths, a virtually nonexistent scientific foundation, and has a false positive rate exceeding 99%. It has not affected the incidence of cerebral palsy. Electronic fetal monitoring has, however, increased the cesarian section rate, with the expected increase in mortality and morbidity risks to mothers and babies alike. This article explains why electronic fetal monitoring remains endorsed as efficacious in the worlds’ labor rooms and courtrooms despite being such a feeble medical modality. It also reviews the reasons professional organizations have failed to condemn the use of electronic fetal monitoring in courtrooms. The failures of tort reform, special cerebral palsy courts, and damage limits to stem the escalating litigation are discussed. Finally, the authors propose using a currently available evidence rule—the Daubert doctrine that excludes “junk science” from the courtroom—as the beginning of the end to cerebral palsy litigation and electronic fetal monitoring’s 40-year masquerade as science.

    Hematological disorders per se represent unusual causes of cerebral ischemia, explaining in young people 4% of strokes. Hematological disorders that induce a thrombotic tendency contribute to overall ischemic stroke risk and may directly cause cerebral ischemia in patients without other risk factors. The frequency of cerebral infarctions caused by prothrombotic states is not known. This review will focus on disorders such as prothrombotic coagulopaties, including resistance to activated protein C and antiphospholipid syndrome as cause of cerebral infarction. Cerebral venous thrombosis and cerebral infarction from arterial origin are the most common form of neurological involvement. Pathophysiological mechanism of stroke in these patients are multiple and can include as in antiphospholipid syndrome embolism from valves abnormalities related to hematological disturbance, as well as thrombosis of extracranial or intracranial vessels. Is clear, however, that prothrombotic states could explains a high percentage of cases of those so called cryptogenic cerebral infarction in young people.

    Lesions of the cerebral white matter (WM) result in focal neurobehavioral syndromes, neuropsychiatric phenomena, and dementia. The cerebral WM contains fiber pathways that convey axons linking cerebral cortical areas with each other and with subcortical structures, facilitating the distributed neural circuits that subserve sensorimotor function, intellect, and emotion. Recent neuroanatomical investigations reveal that these neural circuits are topographically linked by five groupings of fiber tracts emanating from every neocortical area: (1) cortico-cortical association fibers; (2) corticostriatal fibers; (3) commissural fibers; and cortico-subcortical pathways to (4) thalamus and (5) pontocerebellar system, brain stem, and/or spinal cord. Lesions of association fibers prevent communication between cortical areas engaged in different domains of behavior. Lesions of subcortical structures or projection/striatal fibers disrupt the contribution of subcortical nodes to behavior. Disconnection syndromes thus result from lesions of the cerebral cortex, subcortical structures, and WM tracts that link the nodes that make up the distributed circuits. The nature and the severity of the clinical manifestations of WM lesions are determined, in large part, by the location of the pathology: discrete neurological and neuropsychiatric symptoms result from focal WM lesions, whereas cognitive impairment across multiple domains—WM dementia—occurs in the setting of diffuse WM disease. We present a detailed review of the conditions affecting WM that produce these neurobehavioral syndromes, and consider the pathophysiology, clinical effects, and broad significance of the effects of aging and vascular compromise on cerebral WM, in an attempt to help further the understanding, diagnosis, and treatment of these disorders.

    Hospitalized cases of community-acquired pneumonia (CAP) of the elderly with a history of neurologic diseases have not been examined in detail in the past. We extracted 15 cases with a history of neurologic disease (neurological history group, NH, all cases were over 70 years old), and 22 age-matched cases without a history of neurological diseases (non neurologic history group, non-NH) among 47 CAP patients who admitted to our hospital from home during the past year, and compared the two groups in terms of: (1) the score of severity of pneumonia by A-DROP system, (2) outcome (3) the duration of hospitalization, (4) the duration from end of treatment of antibiotic treatment to discharge, compared between the survival discharge cases out of two groups (11 vs 22 cases), (5) the bacteria that were detected. (1) In the NH group, the score was significantly higher than that in the non-NH group. (2) In the NH group, 4 cases died while none did in the non-NH group. (3) In the NH group, it was 30.8 +/- 22.8 (average +/- standard deviation) days, significantly higher than the 17.6 +/- 5.9 days in the non-NH group, (4) In the NH group, it was 16.6 +/- 14.1 days, which was significantly higher than the 6.7 +/- 4.8 days in the non-NH group. (5) In the NH group, there was a high rate of detection of Klebsiella pneumoniae, Escherichia coli and Serratia marcesscense. An original comprehensive plan of treatment and care support is necessary for NH because the NH is different from other CAP conditions.

    Cerebral infarction (CI) is one of severe diseases of central nervous system in neonates, and some infants with CI could have poor prognosis in the long term. This study aimed to analyze the clinical data and prognosis of all neonatal cases with cerebral infarction in recent years and to help future clinical work. Totally 58 neonatal cases with CI admitted to NICU of the hospital from January 1999 to December 2010 were included in this study. We analyzed all clinical data and prognosis by retrospective analysis. Fifty-two term babies and six preterm babies were included. There were altogether 51 cases with asphyxia and 7 with hemorrhagic cerebral infarction. Perinatal hypoxia-ischemia was the most common high-risk factor and it accounted for 46.6%. Seizure was the most frequent initial symptom and the most common clinical manifestation (accounted for 77.6%), and it was followed by intermittent cyanosis, apnea and lethargy. Cerebral CT scan and magnetic resonance imaging were major methods to help to make the diagnosis and they also had close relation with prognosis. Diffusion weighted imaging was very helpful to diagnose infarction in early stage. Left middle cerebral artery was the most common artery to be involved. Supportive therapy and symptomatic treatment were the main methods in the acute stage of neonatal cerebral infarction. Those babies with poor prognosis mostly had large infarction involving cerebral hemisphere, thalamus and basal ganglia. Neonatal cerebral infarction was a severe brain injury affecting long tern nervous system prognosis. Perinatal hypoxia was the most common high-risk factor and seizure was the most frequent initial symptom. Diffusion weighted imaging was valuable to diagnose infarction in early stage. Most of infants with poor prognosis had large infarction involving hemisphere, thalamus and basal ganglia. Early diagnosis with brain imaging would be helpful for rehabilitation therapy and improving prognosis.

    Early stimulation is known to be useful, necessary treatment aimed at developing as much as possible the social psychophysical potential of any child at high environmental and/or biological risk. This group includes children with cerebral palsy, a disorder of the nervous system which may cause retardation in the processes of maturation of the central nervous system and be expressed from the earliest months of the child's life as retardation of psychomotor development. To show the efficiency of early stimulation in children diagnosed as having cerebral palsy and retardation of psychomotor development. A retrospective study was made of 20 children aged between 9 and 41 months with this diagnosis, in the hospital of CIREN (Cuba). They were treated for a period of 1 to 3 months by a multi-disciplinary team and participated in the programme for Early Stimulation. Assessment was made by the Neuropsychology Department at the start and end of the treatment period, using the first part of the Brunet-Lezine scale for the measurement of psychomotor development in early childhood. In all patients there was a favorable course and new abilities were acquired. There was better performance than before the treatment was started and accelerated rate of development during the period of treatment. Patients with cerebral palsy and psychomotor retardation benefit from application of a programme of Early Stimulation.

  4. Antithrombotic therapy in patients with cerebral microbleeds.

    2017-02-01

    Cerebral microbleeds (CMBs) are a radiological marker of cerebral small vessel disease corresponding to small haemosiderin foci identified by blood-sensitive MRI. CMBs are common in older community populations, and in individuals with ischaemic stroke or transient ischaemic attack (TIA), and intracerebral haemorrhage (ICH). We summarize how CMBs might contribute to assessing the future risk of ischaemic stroke and ICH to inform antithrombotic (antiplatelet or anticoagulant) decisions. CMBs are a risk factor for future ischaemic stroke and ICH in all community and hospital populations studied. Following ischaemic stroke/TIA treated with antithrombotics, increasing CMB burden increases the risk of ICH more steeply than that of ischaemic stroke. In ICH populations the risk of recurrent ICH increases with CMB burden, and is highest in those with strictly lobar CMBs or other haemorrhagic findings (e.g. cortical superficial siderosis) suggesting cerebral amyloid angiopathy (CAA). In ischaemic stroke or patients with TIA less than five CMBs should not affect antithrombotic decisions, although with more than five CMBs the risks of future ICH and ischaemic stroke are finely balanced, and antithrombotics might cause net harm. In lobar ICH populations, a high burden of strictly lobar CMBs is associated with CAA and high ICH risk; antithrombotics should be avoided unless there is a compelling indication.

    Using the Near-Infrared Spectroscopy (NIRS), the noninvasive measurement of cerebral oxygen concentration can be achieved in vivo based on the Lambert-Beer Law. In this paper, we discuss the possibility of studying higher brain functions through combining cerebral oxygen saturation and cerebral function measurement. Event-related experiments are introduced to measure the cerebral phronetal function. Time domain curves show sight differences among these experiment results. However, with the aid of DFT, experiment data of all five human volunteers show the frequency near 20 Hz or 40 Hz is evoked depending on the difficulty of the mental tasks. The results demonstrate the feasibility of cerebral functions study by means of cerebral oxygen saturation measurement analyzed in the frequency domain.

    The sulfonylurea receptor 1 (Sur1)-transient receptor potential 4 (Trpm4) channel is an important molecular element in focal cerebral ischemia. The channel is upregulated in all cells of the neurovascular unit following ischemia, and is linked to microvascular dysfunction that manifests as edema formation and secondary hemorrhage, which cause brain swelling. Activation of the channel is a major molecular mechanism of cytotoxic edema and "accidental necrotic cell death." Blockade of Sur1 using glibenclamide has been studied in different types of rat models of stroke: (i) in conventional non-lethal models (thromboembolic, 1-2 h temporary, or permanent middle cerebral artery occlusion), glibenclamide reduces brain swelling and infarct volume and improves neurological function; (ii) in lethal models of malignant cerebral edema, glibenclamide reduces edema, brain swelling, and mortality; (iii) in models with rtPA, glibenclamide reduces swelling, hemorrhagic transformation, and death. Retrospective studies of diabetic patients who present with stroke have shown that those whose diabetes is managed with a sulfonylurea drug and who are maintained on the sulfonylurea drug during hospitalization for stroke have better outcomes at discharge and are less likely to suffer hemorrhagic transformation. Here, we provide a comprehensive review of the basic science, preclinical experiments, and retrospective clinical studies on glibenclamide in focal cerebral ischemia and stroke. We also compare the preclinical work in stroke models to the updated recommendations of the Stroke Therapy Academic Industry Roundtable (STAIR). The findings reviewed here provide a strong foundation for a translational research program to study glibenclamide in patients with ischemic stroke.

    2011-01-01

    Opinion statement Managing patients with malignant cerebral infarction remains one of the foremost challenges in medicine. These patients are at high risk for progressive neurologic deterioration and death due to malignant cerebral edema, and they are best cared for in the intensive care unit of a comprehensive stroke center. Careful initial assessment of neurologic function and of findings on MRI, coupled with frequent reassessment of clinical and radiologic findings using CT or MRI are mandatory to promote the prompt initiation of treatments that will ensure the best outcome in these patients. Significant deterioration in either neurologic function or radiologic findings or both demand timely treatment using the best medical management, which may include osmotherapy (mannitol or hypertonic saline), endotracheal intubation, and mechanical ventilation. Under appropriate circumstances, decompressive craniectomy may be warranted to improve outcome or to prevent death. PMID:21190097

    Protein energy malnutrition is associated with cerebral atrophy which may be detrimental to intellectual development. The aim of this study was to document the anatomical abnormalities which lead to the appearance of cerebral atrophy using magnetic resonance imaging (MRI) in the acute stage of kwashiorkor and to monitor changes during nutritional rehabilitation. Twelve children aged 6 to 37 months requiring admission to hospital for the treatment of kwashiorkor were studied. The children were evaluated clinically, biochemically, and by MRI of their brains on admission and 30 and 90 days later. Brain shrinkage was present in every child on admission. White and grey matter appeared equally affected and the myelination was normal for age. At 90 days, the cerebral changes had resolved in nine and improved substantially in the remainder, by which time serum proteins and weight for age were within the normal range. The findings of this study suggest that brain shrinkage associated with kwashiorkor reverses rapidly with nutritional rehabilitation.

    Spasticity in children cerebral palsy has its own peculiarities due to the presence of pathological tonic reflexes, pathological sinkinetic activity during arbitrary movements, disturbance of coordinative interactions of muscle synergists and antagonists, increase of total reflex excitability. Physiotherapeutic methods, massage, therapeutic exercises, kinesitherapy, biological feedback training (BFT), methods of orthopedic correction, neurosurgery are widely used in the treatment of spasticity. The use of botulinum toxin type A is a new effective approach to the treatment of spasticity that improves motor functions and quality of life of children with children cerebral palsy. It is being used in the treatment of children and adolescence in a polyclinic unit of the Moscow psychoneurological hospital since 2001. The experience of treatment with botulinum and wide implementation of this method indicated that botulinum toxin injections in the complex treatment of spasticity allow to optimize approaches to treatment of children and adolescence with children cerebral palsy and to increase significantly the quality of medical-social rehabilitation of patients.

    There are 2 different kinds of chronic otitis media: Otitis media chronica mesotympanalis and otitis media chronica epitympanalis (cholesteatoma). The incidence of chronic otitis media as reported in literature differs in a wide range. The incidence rates vary between 0.45 and 46%. Both, otitis media chronica mesotympanalis and cholesteatoma, lead to eardrum perforation due to lengthy and recurring inflammations. Furthermore, chronic otitis media is characterized by frequently recurring otorrhea and conductive hearing loss.

    Mohr, J P; Kase, C S

    1983-01-01

    This review enumerates the many proposed mechanisms of vasospasm, including cellular elements, agents derived from the blood and injured cerebral tissues, alteration of calcium: magnesium ratios, free radical reactions, hypothalamic injury, clogging of the subarachnoid space, obstructions of the vasa vasorum and necrosis of the media with subintimal proliferation and intraluminal acidosis. At present, no single agent has been demonstrated as the only source of vasospasm, and whether the disorder is spasm or a chronic arteriopathy remains the subject of argument. The factors influencing the frequency, timing, severity and distribution of angiographically documented vasospasm are discussed, including data from our own population-based study over a 3 year period showing an incidence of vasospasm of 73%. Special emphasis is given to the observation that differences in patient populations play a major role in the incidence and severity of reported vasospasm: those from non-selective populations show a higher incidence of vasospasm and a greater severity of the syndromes attributed to spasm. Hypotheses are offered to account for the low frequency of vasospasm in hemorrhages from arteriovenous malformations and mycotic aneurysms. Clinical syndromes of vasospasm are reviewed, with special emphasis on our own material. The mode of onset and subsequent course of syndromes include those of sudden onset consistent with embolism, and those of gradual onset suggesting a low flow state. Their relationship to the severity of the subarachnoid hemorrhage and the vasospasm is presented. The paucity of syndromes of isolated deep infarcts of the lacunar type is noted. An account is given of the many failed therapies and the future hopes for early surgery. Innovations in medical therapy, including the use of some platelet inhibitors available only in some countries, and rationales for the use of aspirin and even heparin is discussed.

    Abstract Primary intracranial melanomas are uncommon and constitute approximately 1% of all melanoma cases and 0.07% of all brain tumors. In nature, these primary melanomas are very aggressive and can spread to other organs. We report an uncommon case of primary cerebral malignant melanoma—a challenging diagnosis guided by clinical presentations, radiological features, and surgical biopsy results, aiming to emphasize the importance of considering primary melanoma when making differential diagnoses of intracranial lesions. We present a rare case of a primary cerebral melanoma in the left temporal lobe. The mass appeared iso-hypodense on brain computed tomography (CT), short signal on T1-weighted magnetic resonance images (T1WI) and long signal on T2WI. It was not easy to make an accurate diagnosis before surgery. We showed the patient's disease course and reviewed related literatures, for readers’ reference. Written informed consent was obtained from the patient for publication of this case report and any accompanying images. Because of this, there is no need to conduct special ethic review and the ethical approval is not necessary. After surgery, the pathological examination confirmed the diagnosis of melanoma. The patient was discharged without any complications and went on to receive adjuvant radiochemotherapy. It is difficult to diagnose primary cerebral melanoma in the absence of any cutaneous melanosis. A high index of clinical suspicion along with good pathology reporting is the key in diagnosing these extremely rare tumors. PMID:28121927

  5. Cerebral oxygenation and hyperthermia

    PubMed Central

    Bain, Anthony R.; Morrison, Shawnda A.; Ainslie, Philip N.

    2014-01-01

    Hyperthermia is associated with marked reductions in cerebral blood flow (CBF). Increased distribution of cardiac output to the periphery, increases in alveolar ventilation and resultant hypocapnia each contribute to the fall in CBF during passive hyperthermia; however, their relative contribution remains a point of contention, and probably depends on the experimental condition (e.g., posture and degree of hyperthermia). The hyperthermia-induced hyperventilatory response reduces arterial CO2 pressure (PaCO2) causing cerebral vasoconstriction and subsequent reductions in flow. During supine passive hyperthermia, the majority of recent data indicate that reductions in PaCO2 may be the primary, if not sole, culprit for reduced CBF. On the other hand, during more dynamic conditions (e.g., hemorrhage or orthostatic challenges), an inability to appropriately decrease peripheral vascular conductance presents a condition whereby adequate cerebral perfusion pressure may be compromised secondary to reductions in systemic blood pressure. Although studies have reported maintenance of pre-frontal cortex oxygenation (assessed by near-infrared spectroscopy) during exercise and severe heat stress, the influence of cutaneous blood flow is known to contaminate this measure. This review discusses the governing mechanisms associated with changes in CBF and oxygenation during moderate to severe (i.e., 1.0°C to 2.0°C increase in body core temperature) levels of hyperthermia. Future research directions are provided. PMID:24624095

    Reversible cerebral vasoconstriction syndrome is characterized by thunderclap headache associated with multifocal vasoconstriction of cerebral arteries in patients without aneurysmal subarachnoid hemorrhage (SAH). The vasoconstriction reverts within three months. We report a 44-year-old man who had a thunderclap headache during sexual intercourse. A similar episode occurred at rest 36 hours later. The patient had already experienced a thunderclap headache 10 years earlier, during coitus. There were no abnormalities on examination. His brain computed tomography scan was normal and cerebrospinal fluid analysis showed no xanthochromia, 15 WBC/mm³ and 10 RBC/mm³. Lumbar puncture was repeated two days later (WBC = 3/mm³ and RBC = 43/mm³). An initial digital cerebral angiography showed a diffuse segmental intracerebral vasospasm. A new angiography after 15 days was normal. He remains headache-free after twenty six months. In conclusion, patients who have thunderclap headache with normal brain CT and cerebrospinal fluid without xantochromia should be investigated for this syndrome.

    Advancements in molecular biology have led to a greater understanding of the individual proteins responsible for generating cerebral edema. In large part, the study of cerebral edema is the study of maladaptive ion transport. Following acute CNS injury, cells of the neurovascular unit, particularly brain endothelial cells and astrocytes, undergo a program of pre- and post-transcriptional changes in the activity of ion channels and transporters. These changes can result in maladaptive ion transport and the generation of abnormal osmotic forces that, ultimately, manifest as cerebral edema. This review discusses past models and current knowledge regarding the molecular and cellular pathophysiology of cerebral edema. PMID:26661240

    The impact of the mass media on woman's status was addressed at two 1995 conferences: the Fourth World Conference on Women, held in Beijing, China, and the Congress of the World Association for Christian Communication, held in Puebla, Mexico. The globalization process facilitated by the mass media has served to increase the power of patriarchy, with no advantages to the cause of women's rights. Coverage of popular movements has been suppressed out of deference to male-controlled governments. Coverage of the Beijing Conference highlighted celebrities and personal stories, to the exclusion of the economic and political issues under debate. Television has commodified women, reinforcing their oppression. On the other hand, the alternative media, which tend to be decentralized, democratic, low-cost, and low in technology, are presenting women as subjects rather than objects and deconstructing gender stereotypes. Of concern, however, is the tendency of computer technology to widen the gap between social classes and developed and developing countries. Women must use information networks to disseminate information on women's rights and strengthen the links between women throughout the world.

    The unique property of a porous medium, the one that distinguishes it from other solid bodies on the one hand and from simple conduits on the other, is its complicated pore structure. Fluid flow, diffusion, and electrical conduction in porous media take place within extremely complicated microscopic boundaries that in the past made a rigorous solution of the equations of change in the capillary network practically impossible. The past state of affairs is one of the reasons why some of the brilliant and successful practitioners in the field of flow through porous media have tried, as much as possible, to stick with the continuum approach in which no attention is paid to pores or pore structure. Another reason is that the continuum approach is often adequate for the phenomenological description of macroscopic transport processes in porous media. This book has been written with the primary purpose of presenting in an organized manner the most pertinent information available on the role of pore structure and then putting it to use in the interpretation of experimental data and the results of model calculations.

    Pineal calcification and low melatonin have been shown to be risk factors for stroke in animal studies; however, there are limited clinical data on the association of pineal calcification and stroke in humans. All computed tomographic (CT) scans of the brains of patients >15 years of age during the year 2011 at a university teaching hospital were retrospectively reviewed. Patient medical charts were used to obtain the risk factors for stroke, including diabetes, hypertension, dyslipidemia, age, and sex. Cerebral infarction was identified by having clinical syndromes of stroke and a positive CT scan. Patients with embolic or hemorrhagic stroke were excluded. Pineal calcification was evidenced by the CT scans. The association of various stroke risk factors and cerebral infarction were calculated using logistic regression analysis. A total of 1614 patients were included, and symptomatic cerebral infarction was identified in 620 patients (38.4%). Regarding stroke risk factors in symptomatic cerebral infarction patients, the majority of patients were male (356 [57.4%]), >50 years of age (525 [84.7%]), and had hypertension (361 [58.2%]); some had diabetes (199 [32.1%]) and dyslipidemia (174 [28.1%]). Pineal calcification was found in 1081 patients (67.0%), with a male:female ratio of 1.5:1. Significant factors related to cerebral infarction by univariate logistic regression were age >50 years, hypertension, diabetes, dyslipidemia, and pineal calcification. Pineal calcification as a risk factor for cerebral infarction had an adjusted odds ratio of 1.35 (95% confidence interval 1.05-1.72). Pineal calcification may be a potential new contributor to cerebral infarction. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Background: Paraplegia is mainly caused by spinal cord disease and rarely occurs due to head trauma. In this report, we describe a case of paraplegia caused by cerebral contusions in the bilateral precentral gyri. Case Description: A 72-year-old man was admitted to our hospital with mildly impaired consciousness and severe pure motor paralysis in both legs. He was healthy until the morning of the day, but his wife found him injured in front of his house upon returning home. He had a subcutaneous hematoma in his occipital region, and seemed to have slipped by accident. Computed tomography of the brain and magnetic resonance imaging (MRI) of his spinal cord revealed no apparent cause of the paraplegia, although an MRI of his brain clearly revealed cerebral contusions in the bilateral precentral gyri. The cerebral contusion was diagnosed as the cause of pure motor paralysis of lower extremities. He received rehabilitation, and manual muscle testing of his legs revealed improvements. In the subacute phase, the precentral gyrus lesion disappeared on MRI. Conclusion: We must emphasize that cerebral contusion can be a differential diagnosis for paraplegia. In the acute phase, fluid-attenuated inversion recovery (FLAIR) MRI coronal and sagittal images are useful for identifying precentral gyri contusions. Paraplegia caused by a cerebral contusion may be misdiagnosed as a spinal concussion due to the disappearance of the precentral gyrus lesion on FLAIR MRI in the subacute phase. PMID:27904755

    The aim of this study was to prospectively investigate whether the structure of cerebral small-resistance arteries is related to cerebral perfusion parameters as measured with dynamic susceptibility-weighted contrast magnetic resonance imaging (DSC-MRI) in a selected cohort of hypertensive and normotensive patients. Ten hypertensive and 10 normotensive patients were included in the study. All patients underwent neurosurgical intervention for an intracranial tumor and were investigated with DSC-MRI at 1.5 T. Cerebral small-resistance arteries were dissected from a small portion of morphologically normal cerebral tissue and mounted on an isometric myograph for the measurement of the media-to-lumen (M/L) ratio. A quantitative assessment of cerebral blood flow (CBF) and volume (CBV) was performed with a region-of-interest approach. Correlation coefficients were calculated for normally distributed variables. The institutional review board approved the study, and informed consent was obtained from all patients. Compared with normotensive subjects, hypertensive patients had significantly lower regional CBF (mL/100 g/min) in the cortical grey matter (55.63 ± 1.90 vs 58.37 ± 2.19, p < 0.05), basal ganglia (53.34 ± 4.39 vs 58.22. ± 4.33, p < 0.05), thalami (50.65 ± 3.23 vs 57.56 ± 4.45, p < 0.01), subcortical white matter (19.32 ± 2.54 vs 22.24 ± 1.9, p < 0.05), greater M/L ratio (0.099 ± 0.013 vs 0.085 ± 0.012, p < 0.05), and lower microvessel density (1.66 ± 0.67 vs 2.52 ± 1.28, p < 0.05). A statistically significant negative correlation was observed between M/L ratio of cerebral arteries and CBF in the cortical grey matter (r = -0.516, p < 0.05), basal ganglia (r = -0.521, p < 0.05), thalami (r = -0.527 p < 0.05), and subcortical white matter (r = -0.612, p < 0.01). Our results indicate that microvascular structure might play a role in controlling CBF, with possible clinical consequences.

    Structural alterations in the microcirculation may be considered an important mechanism of organ damage. An increased media-to-lumen ratio of subcutaneous small resistance arteries has been demonstrated to predict the development of cardiocerebrovascular events in hypertensive patients. Alterations in the structure of small cerebral arteries have been demonstrated in animal models of experimental or genetic hypertension. However, no evaluation with reliable techniques has ever been performed in humans. Twenty-eight participants were included in the present study: they were 13 hypertensive patients and 15 normotensive individuals. All participants underwent a neurosurgical intervention for benign or malign tumors. A small portion of morphologically normal cerebral tissue was excised from surgical samples and examined. Cerebral small resistance arteries (relaxed diameter around 200 mum) were dissected and mounted on an isometric and isobaric myograph, and the tunica media to internal lumen ratio was measured. In addition, cerebral cortical microvessel density (MVD) was also evaluated. The tissue was sectioned and stained for CD31, and MVD was measured with an automated image analyzer (percentage of area stained). Blood pressure values were evaluated, before surgical intervention, by standard sphygmomanometry. M/L was significantly greater and MVD significantly lower in hypertensive patients than that in normotensive individuals. No difference between groups in collagen content or mechanical properties of cerebral small arteries was observed. Our results indicate that structural alterations of small cerebral vessels are present in hypertensive patients compared with normotensive individuals, similar to those previously observed in subcutaneous small arteries.

    Beach chair position is considered a potential risk factor for central neurological events particularly if combined with low blood pressure. The aim of this study was to assess the impact of regional anesthesia on cerebral blood flow and neurobehavioral outcome. This is a prospective, assessor-blinded observational study evaluating patients in the beach chair position undergoing shoulder surgery under regional anesthesia. University hospital operating room. Forty patients with American Society of Anesthesiologists classes I-II physical status scheduled for elective shoulder surgery. Cerebral saturation and blood flow of the middle cerebral artery were measured prior to anesthesia and continued after beach chair positioning until discharge to the postanesthesia care unit. The anesthesiologist was blinded for these values. Controlled hypotension with systolic blood pressure≤100mm Hg was maintained during surgery. Neurobehavioral tests and values of regional cerebral saturation, bispectral index, the mean maximal blood flow of the middle cerebral artery, and invasive blood pressure were measured prior to regional anesthesia, and measurements were repeated after placement of the patient on the beach chair position and every 20 minutes thereafter until discharge to postanesthesia care unit. The neurobehavioral tests were repeated the day after surgery. The incidence of cerebral desaturation events was 5%. All patients had a significant blood pressure drop 5 minutes after beach chair positioning, measured at the heart as well as the acoustic meatus levels, when compared with baseline values (P<.05). There was no decrease in either the regional cerebral saturation (P=.136) or the maximal blood flow of the middle cerebral artery (P=.212) at the same time points. Some neurocognitive tests showed an impairment 24 hours after surgery (P<.001 for 2 of 3 tests). Beach chair position in patients undergoing regional anesthesia for shoulder surgery had no major impact on

    Abstract Calcification of the middle cerebral artery (MCA) is uncommon in the healthy elderly. Whether calcification of the MCA is associated with cerebral ischemic stroke remains undetermined. We intended to investigate the association using Agatston calcium scoring of the MCA. This study retrospectively included 354 subjects with ischemic stroke in the MCA territory and 1518 control subjects who underwent computed tomography (CT) of the brain. We recorded major known risk factors for ischemic stroke, including age, gender, hypertension, diabetes mellitus, smoking, hyperlipidemia, and obesity, along with the MCA calcium burden, measured with the Agatston calcium scoring method. Univariate and modified logistic regression analyses were performed to examine the association between the MCA calcification and ischemic stroke. The univariate analyses showed significant associations of ischemic stroke with age, hypertension, diabetes mellitus, smoking, total MCA Agatston score, and the presence of calcification on both or either side of the MCA. Subjects with the presence of MCA calcification on both or either side of the MCA were 8.46 times (95% confidence interval, 4.93–14.53; P < 0.001) more likely to have a cerebral infarct than subjects without MCA calcification after adjustment for the major known risk factors, including age, hypertension, diabetes mellitus, and smoking. However, a higher degree of MCA calcification reflected by the Agatston score was not associated with higher risk of MCA ischemic stroke after adjustment for the confounding factors and presence of MCA calcification. These results suggest that MCA calcification is associated with ischemic stroke in the MCA territory. Further prospective studies are required to verify the clinical implications of the MCA calcification. PMID:26683969

    The reversible cerebral vasoconstriction syndrome (RCVS) is an under-estimated transient acute cerebrovascular disorder. It has long been mistaken as central nervous system vasculitis whereas it is now believed to result from an acute but prolonged vasospasm of cerebral arteries. This disorder can be precipitated by postpartum or vasoactive drug. However, it occurs spontaneously in a significant number of cases. The characteristic clinico-radiological presentation and disease course of the RCVS has been delineated only recently. Mean age at onset is 40-45 years, with a female predominance. A provocative factor can be identified in 12-60% out of the patients. Clinical presentation is predominantly marked by recurrent thunderclap headaches, but can be complicated with focal neurological deficit or seizures. Brain imaging is normal in most cases, but can reveal hemorrhagic or ischemic complications. Cortical subarachnoid hemorrhage is a suggestive finding. A posterior reversible encephalopathy syndrome (PRES) can be seen occasionally. Cerebral angiography reveals multifocal arterial narrowing with string and bead appearance. Cerebrospinal fluid reveals no or mild abnormalities. The disease resumes spontaneously within several days to weeks, whereas vasoconstriction reverses within 1 to 3 months. This clinico-radiological presentation should be promptly recognized in order to avoid unnecessary investigations and aggressive treatment, and lead to search for a triggering factor. Further studies are required in order to clarify the precipitating role of several drugs, and clinical trials are needed to reduce the occurrence of strokes.

    Bridging patient/"customer" issues and business aspects can be aided through developing a specific nursing basis for hospitality. The ancient practice of hospitality has evolved into three distinct levels: public, personal and therapeutic. Understanding these levels is helpful in integrating various dimensions of guest relations programs in hospitals into a more comprehensive vision. Hospitality issues must become a greater part of today's nursing management.

    Orthostatic dizziness without orthostatic hypotension is common but underlying pathophysiology is poorly understood. This study describes orthostatic cerebral hypoperfusion syndrome (OCHOs). OCHOs is defined by (1) abnormal orthostatic drop of cerebral blood flow velocity (CBFv) during the tilt test and (2) absence of orthostatic hypotension, arrhythmia, vascular abnormalities, or other causes of abnormal orthostatic CBFv. This retrospective study included patients referred for evaluation of unexplained orthostatic dizziness. Patients underwent standardized autonomic testing, including 10 min of tilt test. The following signals were monitored: heart rate, end tidal CO2, blood pressure, and CBFv from the middle cerebral artery using transcranial Doppler. Patients were screened for OCHOs. Patients who fulfilled the OCHOs criteria were compared to age- and gender-matched controls. From 1279 screened patients, 102 patients (60/42 women/men, age 51.1 ± 14.9, range 19-84 years) fulfilled criteria of OCHOs. There was no difference in baseline supine hemodynamic variables between OCHOs and the control group. During the tilt, mean CBFv decreased 24.1 ± 8.2% in OCHOs versus 4.2 ± 5.6% in controls (p < 0.0001) without orthostatic hypotension in both groups. Supine mean blood pressure (OCHOs/controls, 90.5 ± 10.6/91.1 ± 9.4 mmHg, p = 0.62) remained unchanged during the tilt (90.4 ± 9.7/92.1 ± 9.6 mmHg, p = 0.2). End tidal CO2 and heart rate responses to the tilt were normal and equal in both groups. OCHOs is a novel syndrome of low orthostatic CBFv. Two main pathophysiological mechanisms are proposed, including active cerebral vasoconstriction and passive increase of peripheral venous compliance. OCHOs may be a common cause of orthostatic dizziness.

    Neurologic diseases of the cerebrum are relatively common in cattle. In calves, the primary cerebral disorders are polioencephalomalacia, meningitis, and sodium toxicity. Because diagnostic testing is not always readily available, the practitioner must often decide on a course of treatment based on knowledge of the likely disease, as well as his or her own clinical experience. This is particularly true with neurologic diseases in which the prognosis is often poor and euthanasia may be the most humane outcome. This article reviews the most common diseases affecting the cerebrum of calves with a focus on pathophysiology, diagnosis, and treatment.

    Objective: HIV enters the brain soon after infection causing neuronal damage and microglial/astrocyte dysfunction leading to neuropsychological impairment. We examined the impact of HIV on resting cerebral blood flow (rCBF) within the lenticular nuclei (LN) and visual cortex (VC). Methods: This cross-sectional study used arterial spin labeling MRI (ASL-MRI) to measure rCBF within 33 HIV+ and 26 HIV− subjects. Nonparametric Wilcoxon rank sum test assessed rCBF differences due to HIV serostatus. Classification and regression tree (CART) analysis determined optimal rCBF cutoffs for differentiating HIV serostatus. The effects of neuropsychological impairment and infection duration on rCBF were evaluated. Results: rCBF within the LN and VC were significantly reduced for HIV+ compared to HIV− subjects. A 2-tiered CART approach using either LN rCBF ≤50.09 mL/100 mL/min or LN rCBF >50.09 mL/100 mL/min but VC rCBF ≤37.05 mL/100 mL/min yielded an 88% (29/33) sensitivity and an 88% (23/26) specificity for differentiating by HIV serostatus. HIV+ subjects, including neuropsychologically unimpaired, had reduced rCBF within the LN (p = 0.02) and VC (p = 0.001) compared to HIV− controls. A temporal progression of brain involvement occurred with LN rCBF significantly reduced for both acute/early (<1 year of seroconversion) and chronic HIV-infected subjects, whereas rCBF in the VC was diminished for only chronic HIV-infected subjects. Conclusion: Resting cerebral blood flow (rCBF) using arterial spin labeling MRI has the potential to be a noninvasive neuroimaging biomarker for assessing HIV in the brain. rCBF reductions that occur soon after seroconversion possibly reflect neuronal or vascular injury among HIV+ individuals not yet expressing neuropsychological impairment.

    Neural stem cells in the subventricular zone (SVZ) of the lateral ventricle of adult rodent brain generate oligodendrocyte progenitor cells (OPCs) that disperse throughout the corpus callosum and striatum where some of OPCs differentiate into mature oligodendrocytes. Studies in animal models of stroke demonstrate that cerebral ischemia induces oligodendrogenesis during brain repair processes. This article will review evidence of stroke-induced proliferation and differentiation of OPCs that are either resident in white matter or are derived from SVZ neural progenitor cells and of therapies that amplify endogenous oligodendrogenesis in ischemic brain.

    Although most patients with takotsubo cardiomyopathy have a favorable outcome, complications are not uncommon. Recent studies have reported an increase in incidence of cardioembolic complications; however, the association between takotsubo cardiomyopathy and stroke, in particular thromboembolic cerebral infarction, remains unclear. We reported a 44-year-old woman who had a cerebral infarction resulting from takotsubo cardiomyopathy. She had felt chest discomfort a few days prior to infarction, and later developed left hemiparesis. Head magnetic resonance imaging (MRI) revealed acute infarction in the right insular cortex and occlusion of the right middle cerebral artery at the M2 segment. Echocardiogram revealed a takotsubo-like shape in the motion of the left ventricular wall, and coronary angiography showed neither coronary stenosis nor occlusion. Cerebral infarction resulting from takotsubo cardiomyopathy was diagnosed and treatment with anticoagulant was started. MRI on the eighth day after hospitalization showed recanalization of the right middle cerebral artery and no new ischemic lesions. The findings of the 19 previously published cases who had cerebral infarction resulting from takotsubo cardiomyopathy were also reviewed and showed the median interval between takotsubo cardiomyopathy and cerebral infarction was approximately 1 week and cardiac thrombus was detected in 9 of 19 patients. We revealed that thromboembolic events occurred later than other complications of takotsubo cardiomyopathy and longer observation might be required due to possible cardiogenic cerebral infarction. Anticoagulant therapy is recommended for patients with takotsubo cardiomyopathy with cardiac thrombus or a large area of akinetic left ventricle.

    Thrombolytic treatment in the early stage of ischemic cerebral attacks requires rapid confirmation of the diagnosis and topographic localization. Unusual clinical features can lead to misdiagnosis with the risk of delaying optimal therapeutic management. We report the cases of two patients who experienced acute tetraparesis without any associated encephalic sign, consistent with the diagnosis of spinal cord injury. Cervical magnetic resonance imaging (MRI) was normal. Conversely, cerebral MRI displayed in both cases bilateral hemispheric infarction. Two ischemic lesions were revealed in the territory of both anterior cerebral arteries in the first patient, while the second patient had a bilateral infarction in the posterior arms of both internal capsules. In case of tetraparesis, emergency spinal cord MRI should be performed to rule out neurosurgical etiologies and ischemia. If negative, cerebral MRI should be performed at the same time to look for early cerebral infarction in both hemispheres and determine the indication for thrombolysis.

    Cerebral microbleeds (CMBs) are small and round perivascular hemosiderin depositions detectable by gradient echo sequences or susceptibility-weighted imaging. Cerebral microbleeds are common among patients with hypertension, cerebral ischemia, or cerebral amyloid angiopathy. In this article, we describe uncommon causes of CMBs. We searched Pubmed with the keyword CMBs for relevant studies and looked for different uncommon causes of CMBs. CMBs have several uncommon etiologies including posterior reversible encephalopathy syndrome, infective endocarditis, brain radiation therapy, cocaine abuse, thrombotic thrombocytopenic purpura, traumatic brain injury, intravascular lymphomatosis or proliferating angio-endotheliomatosis, moyamoya disease, sickle cell anemia/β-thalassemia, cerebral autosomal dominant arteriopathy subcortical infarcts, and leukoencephalopathy (CADASIL), genetic syndromes, or obstructive sleep apnea. Understanding the uncommon causes of CMBs is not only helpful in diagnosis and prognosis of some of these rare diseases, but can also help in better understanding different pathophysiology involved in the development of CMBs.

    The central functions of norepinephrine (NE) are a recent discovery: regulation of alertness and of the wakefulness-sleep cycle, maintenance of attention, memory and learning, cerebral plasticity and neuro-protection. The anatomical, histological, biochemical and physiological properties of the central noradrenergic system: extreme capacity for ramification and arborization; slow conduction, non-myelinized axons with extrasynaptic varicosities producing and releasing NE; frequency of co-transmission phenomena, and; neuromodulation with fiber effect responsible for improvement in the signal over background noise ratio and selection of significant stimuli form a true interface between the outside world and the central nervous system, notably for the neocortex in the context of the cognitive treatment of information. This central noradrenergic system is involved in the neurophysiology and the clinical features of cerebral aging (ideation-motor and cognitive function slowing down, loss of behavioral adjustment), neuro-degenerative disorders (SDAT, Parkinson's disease), certain aspects of depression and less obvious conditions (head injuries, sequelae of cerebrovascular accidents, sub-cortical dementia). The recent development of medications improving alertness (adrafinil, modafinil) with a pure central action and specifically noradrenergic, may contribute to an improvement in these multifactorial disorders.

    Cerebral cartography and connectomics pursue similar goals in attempting to create maps that can inform our understanding of the structural and functional organization of the cortex. Connectome maps explicitly aim at representing the brain as a complex network, a collection of nodes and their interconnecting edges. This article reflects on some of the challenges that currently arise in the intersection of cerebral cartography and connectomics. Principal challenges concern the temporal dynamics of functional brain connectivity, the definition of areal parcellations and their hierarchical organization into large-scale networks, the extension of whole-brain connectivity to cellular-scale networks, and the mapping of structure/function relations in empirical recordings and computational models. Successfully addressing these challenges will require extensions of methods and tools from network science to the mapping and analysis of human brain connectivity data. The emerging view that the brain is more than a collection of areas, but is fundamentally operating as a complex networked system, will continue to drive the creation of ever more detailed and multi-modal network maps as tools for on-going exploration and discovery in human connectomics.

  16. Monitoring of cerebral autoregulation.

    PubMed

    Czosnyka, Marek; Miller, Chad

    2014-12-01

    Pressure autoregulation is an important hemodynamic mechanism that protects the brain against inappropriate fluctuations in cerebral blood flow in the face of changing cerebral perfusion pressure (CPP). Static autoregulation represents how far cerebrovascular resistance changes when CPP varies, and dynamic autoregulation represents how fast these changes happen. Both have been monitored in the setting of neurocritical care to aid prognostication and contribute to individualizing CPP targets in patients. Failure of autoregulation is associated with a worse outcome in various acute neurological diseases. Several studies have used transcranial Doppler ultrasound, intracranial pressure (ICP with vascular reactivity as surrogate measure of autoregulation), and near-infrared spectroscopy to continuously monitor the impact of spontaneous fluctuations in CPP on cerebrovascular physiology and to calculate derived variables of autoregulatory efficiency. Many patients who undergo such monitoring demonstrate a range of CPP in which autoregulatory efficiency is optimal. Management of patients at or near this optimal level of CPP is associated with better outcomes in traumatic brain injury. Many of these studies have utilized the concept of the pressure reactivity index, a correlation coefficient between ICP and mean arterial pressure. While further studies are needed, these data suggest that monitoring of autoregulation could aid prognostication and may help identify optimal CPP levels in individual patients.

    The clinical features and long-term outcome of seven patients with delayed cerebral radiation necrosis (DCRN) are described. Radiotherapy had been given for pituitary tumour (1), astrocytoma (2), pinealoma (2), craniopharyngioma (1) and parotid carcinoma (1). The mean latency to onset of the first neurological symptoms was 22 months (range 6-40 months), and mean duration of follow-up was 86 months (range 60-126). Three patients died at a mean of 84 months after radiotherapy (range 62-98). A fourth patient probably died from metastatic disease. Three patients remain alive, albeit severely disabled, after 5-10 years. The illness typically ran a stepwise course, with fits and stroke-like episodes occurring against a background of progressive dementia and somnolence. CT and MRI scans showed progressive ventricular dilatation associated with cerebral atrophy and diffuse or focal changes in the white matter. Four patients had had two or more neurosurgical procedures after the radiotherapy. In only one of the seven patients was the diagnosis made at presentation. DCRN produces a distinctive clinical picture, yet remains a poorly recognized complication of cranial irradiation.

    To register the prevalence of cerebral palsy (CP) and determine etiological factors for the condition. Population based study with registration of CP-cases in children born during the 30-year period 1970-99. Cases with postneonatal etiology were excluded. 166 CP-cases were registered among 70 824 children, a prevalence of 2.3 per 1000 live born infants. The prevalence did not change significantly during the period. 66 (40%) were low birthweight infants (LBWIs; <2500 g), and 100 (60%) normal birthweight infants (NBWIs; > or = 2500 g). The origin was classified as prenatal in 37 (22%), perinatal/neonatal in 78 (47%) and unclassifiable in 51 (31 %). In LBWIs 39/66 (59%) had a perinatal/neonatal etiology, most frequently intra- or periventricular hemorrhages (IVH/PVH) and/or periventricular leukomalacia (PVL) or cerebral infarctions (CI) (17; 44%). In NBWIs 39/100 (39%) had a perinatal etiology, most frequently hypoxic-ischemic encephalopathy (HIE) (31; 79%). In a substantial percentage of CP-cases perinatal/neonatal brain injury was classified as the cause. Among these IVH/PVH/PVL/CI dominated in LBWIs, while HIE dominated in NBWIs. Our data may point to preventability of a larger part of CP than earlier suggested.

    Cerebral sinus venous thrombosis (CSVT) is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT) and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment. PMID:24347950

    Cerebral hyperperfusion syndrome (CHS) after carotid endarterectomy is characterised by ipsilateral headache, hypertension, seizures, and focal neurological deficits. If not treated properly it can result in severe brain oedema, intracerebral or subarachnoid haemorrhage, and death. Knowledge of CHS among physicians is limited. Most studies report incidences of CHS of 0-3% after carotid endarterectomy. CHS is most common in patients with increases of more than 100% in perfusion compared with baseline after carotid endarterectomy and is rare in patients with increases in perfusion less than 100% compared with baseline. The most important risk factors in CHS are diminished cerebrovascular reserve, postoperative hypertension, and hyperperfusion lasting more than several hours after carotid endarterectomy. Impaired autoregulation as a result of endothelial dysfunction mediated by generation of free oxygen radicals is implicated in the pathogenesis of CHS. Treatment strategies are directed towards regulation of blood pressure and limitation of rises in cerebral perfusion. Complete recovery happens in mild cases, but disability and death can occur in more severe cases. More information about CHS and early institution of adequate treatment are of paramount importance in order to prevent these potentially severe complications.

    Cerebral amyloid angiopathy (CAA) is a disorder characterized by the accumulation of amyloid proteins in the small and medium-sized blood vessels of the leptomeninges and central nervous system. Amyloid β protein (Aβ), immunoglobulin light chains, cystatin C, prion protein (PrP), ABri/ADan, transthyretin, and gelsoline, are all associated with CAA. While most CAA patients demonstrated sporadic Aβ-type amyloid deposition, a small number of patients present with familial forms, e.g. Dutch-type hereditary cerebral hemorrhage with amyloidosis (HCHWA-D), Icelandic-type HCHWA (HCHWA-I), familial British dementia (FBD), familial Danish dementia (FDD), and PrP-CAA. Deposited amyloid proteins damage smooth muscle cells in blood vessel walls leading to pathological appearances calling 'double-barreled' changes, fibrinoid necrosis, and microaneurysms. These structural abnormalities result in microinfarcts and hemorrhages in the central nervous system. Recurrent hemorrhage is a common clinical manifestation in patients with CAA; however, small multiple infarctions, progressive dementia, transient neurological symptoms, and CAA-related inflammation can also occur. The pathomechanisms of CAA remain unknown. Although improvements in imaging techniques have allowed us to identify patients with CAA more readily, pathological examination is still essential for a definite diagnosis. There have been no curative treatments for CAA so far.

    Reversible cerebral vasoconstriction syndrome (RCVS) is a clinical-radiological syndrome characterised by severe thunderclap headaches with or without other neurological symptoms and multifocal constriction of cerebral arteries that usually resolves spontaneously within 3 months. Most patients recover completely, but up to 10% have a permanent neurological disability and some even die. Previously RCVS has been described in many clinical contexts and under different names with the term RCVS first being suggested in 2007 to unify the group. The condition may be spontaneous, but in up to 60% of cases it is secondary to another cause, including vasoactive substances (medications and illicit drugs), blood products and the post-partum state. It is believed to have a similar pathophysiological mechanism to the posterior reversible encephalopathy syndrome (PRES), and both can occur in similar clinical contexts and are frequently associated. Treatment options include calcium channel antagonists. RCVS occurs in a broad range of clinical situations making it an increasingly recognised condition about which doctors in various specialties need to be aware. © 2014 Royal Australasian College of Physicians.

    The gluconeogenesis pathway, which has been known to normally present in the liver, kidney, intestine, or muscle, has four irreversible steps catalyzed by the enzymes: pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase. Studies have also demonstrated evidence that gluconeogenesis exists in brain astrocytes but no convincing data have yet been found in neurons. Astrocytes exhibit significant 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 activity, a key mechanism for regulating glycolysis and gluconeogenesis. Astrocytes are unique in that they use glycolysis to produce lactate, which is then shuttled into neurons and used as gluconeogenic precursors for reduction. This gluconeogenesis pathway found in astrocytes is becoming more recognized as an important alternative glucose source for neurons, specifically in ischemic stroke and brain tumor. Further studies are needed to discover how the gluconeogenesis pathway is controlled in the brain, which may lead to the development of therapeutic targets to control energy levels and cellular survival in ischemic stroke patients, or inhibit gluconeogenesis in brain tumors to promote malignant cell death and tumor regression. While there are extensive studies on the mechanisms of cerebral glycolysis in ischemic stroke and brain tumors, studies on cerebral gluconeogenesis are limited. Here, we review studies done to date regarding gluconeogenesis to evaluate whether this metabolic pathway is beneficial or detrimental to the brain under these pathological conditions. PMID:28101056

    now, from the massive clinical practices, most of Chinese clinical specialists propose the combination therapy of albendazole and praziquantel for cerebral cysticercosis with simultaneous administration of steroids, especially in the first course. In addition, administration of praziquantel at a high dose can become a diagnostic treatment for suspected cerebral cysticercosis and serve as a supplement of the currently available diagnostic methods, such as diagnoses based on the clinical features, immunology, CT and MRI imaging, etc., in some atypical cerebral cysticercosis patients. Praziquantel and albendazole treatments have some adverse reactions, and to control these adverse effects, all the cerebral cysticercosis patients should be treated in hospital. According to the type of cerebral cysticercosis, especially for intracranial hypertension type and meningocephalitis type, the dosages of anti-cysticercus drugs need to follow a gradually increasing pattern. During the period of anti-cysticercosis treatments, steroids and/or dehydrating agents need be administered which can alleviate the intracranial hypertension and so on. Traditional Chinese medicines have been also used in the treatment of cerebral cysticercosis and achieve satisfactory outcomes. However, the compound prescription of traditional Chinese medicines is very complex, and the effective components are not fully clear. Some cerebral cysticercosis patients with very high intracranial tension could not receive antiparasitic treatment immediately, and surgical treatment is required. Chinese surgeons also achieve some successful experiences, but not all the cysticercus can be removed completely during the surgery. Therefore, antiparasitic drugs are still needed after the operation. The rehabilitative treatment is supplementary in the therapy of cerebral cysticercosis. In China, the rehabilitative treatment of cerebral cysticercosis is still at the initial stage. These lessons and experiences in China can be

    Summary Background: A true aneurysym is a dilation of arterial lumen as a consequence of congenital or acquired abnormalities leading to a reduction of mechanical resistance of vascular wall, most commonly caused by its defected structure in the form of absence or weakening of the muscular and/or elastic layer. From the pathophysiological point of view, cerebral aneurysms can be classified as ‘saccular’ – most commonly occurring, and ‘other types’, including fusiform/dolichoectatic, dissecting, serpentine, posttraumatic, mycotic and giant aneurysms with or without intra-aneurysmal thrombosis. Case Report: We present a rare case of a patient with multiple fusiform dilations of cerebral vessels and giant fusiform aneurysm in supraclinoid segment of the internal carotid artery. The patient presented to hospital because of sudden, severe vertigo with nausea, impaired balance and disturbed vision. Vascular anomalies were detected on CT scanning without contrast. The diagnostic work-up was complemented by CT angiography, MRI and cerebral angiography. Conclusions: Aneurysm located within the intracranial arteries is one of the most common vascular defects of the brain. The number, size and location of aneurysms are highly variable. Aneurysms can have either supra- or infratentorial location, affecting a single or multiple arteries within one or both brain hemispheres. There is often a correlation between the location of the aneurysm and its etiology, as in case of so-called mirror-image aneurysms. Symmetrically located aneurysms may indicate a defect in vascular structure. Asymmetric location, as in the patient described above, is more likely due to acquired causes, mainly atherosclerosis, but also septic emboli or blood disorders. PMID:22802866

    Malignant middle cerebral artery infarction is a devastating type of ischemic stroke whose clinical predictors remain scarcely known. The present study aims to improve the knowledge about the prognosis factors through an analysis of a malignant middle cerebral artery infarction sample of patients from our stroke registry. From a total of 1,396 patients with ischemic stroke in the middle cerebral artery included in the "Sagrat Cor Hospital of Barcelona Stroke Registry", we identified 32 patients with malignant middle cerebral artery infarction (2.3%). Demographic, anamnestic, clinical, and outcome variables in this subgroup of patients were compared with those of the middle cerebral artery. The independent predictive value of each variable on the development of malignant middle cerebral artery infarction was assessed with a logistic regression analysis. The mean age was 74.7 (SD, 11.4) years and 50% were males. In-hospital death was observed in eight patients (25%) and early bad prognosis (in-hospital death or severe residual focality at discharge) was present in 16 patients (50%). Decreased consciousness (OR: 4.17; 95% CI: 2.02-8.61), presence of nausea or vomiting (OR: 3.65; 95% CI: 1.40-8.49), and heavy smoking (> 20 cigarettes/day; OR: 2.62; 95% CI: 1.03-6.64) appeared to be independent prognostic factors for malignant middle cerebral artery infarction in the multivariate analysis. Malignant middle cerebral artery infarction is an infrequent clinical condition associated with poor prognosis and high mortality rate. In our sample, decreased consciousness, nausea or vomiting, and heavy smoking are the main clinical factors associated.

  14. Influence of medial collagen organization and axial in situ stretch on saccular cerebral aneurysm growth.

    Eriksson, Thomas; Kroon, Martin; Holzapfel, Gerhard A

    2009-10-01

    A model for saccular cerebral aneurysm growth, proposed by Kroon and Holzapfel (2007, "A Model for Saccular Cerebral Aneurysm Growth in a Human Middle Cerebral Artery," J. Theor. Biol., 247, pp. 775-787; 2008, "Modeling of Saccular Aneurysm Growth in a Human Middle Cerebral Artery," ASME J. Biomech. Eng., 130, p. 051012), is further investigated. A human middle cerebral artery is modeled as a two-layer cylinder where the layers correspond to the media and the adventitia. The immediate loss of media in the location of the aneurysm is taken to be responsible for the initiation of the aneurysm growth. The aneurysm is regarded as a development of the adventitia, which is composed of several distinct layers of collagen fibers perfectly aligned in specified directions. The collagen fibers are the only load-bearing constituent in the aneurysm wall; their production and degradation depend on the stretch of the wall and are responsible for the aneurysm growth. The anisotropy of the surrounding media was modeled using the strain-energy function proposed by Holzapfel et al. (2000, "A New Constitutive Framework for Arterial Wall Mechanics and a Comparative Study of Material Models," J. Elast., 61, pp. 1-48), which is valid for an elastic material with two families of fibers. It was shown that the inclusion of fibers in the media reduced the maximum principal Cauchy stress and the maximum shear stress in the aneurysm wall. The thickness increase in the aneurysm wall due to material growth was also decreased. Varying the fiber angle in the media from a circumferential direction to a deviation of 10 deg from the circumferential direction did, however, only show a little effect. Altering the axial in situ stretch of the artery had a much larger effect in terms of the steady-state shape of the aneurysm and the resulting stresses in the aneurysm wall. The peak values of the maximum principal stress and the thickness increase both became significantly higher for larger axial

  15. Feasibility of absolute cerebral tissue oxygen saturation during cardiopulmonary resuscitation

    PubMed Central

    2013-01-01

    Introduction Current monitoring during cardiopulmonary resuscitation (CPR) is limited to clinical observation of consciousness, breathing pattern and presence of a pulse. At the same time, the adequacy of cerebral oxygenation during CPR is critical for neurological outcome and thus survival. Cerebral oximetry, based on near-infrared spectroscopy (NIRS), provides a measure of brain oxygen saturation. Therefore, we examined the feasibility of using NIRS during CPR. Methods Recent technologies (FORE-SIGHT™ and EQUANOX™) enable the monitoring of absolute cerebral tissue oxygen saturation (SctO2) values without the need for pre-calibration. We tested both FORE-SIGHT™ (five patients) and EQUANOX Advance™ (nine patients) technologies in the in-hospital as well as the out-of-hospital CPR setting. In this observational study, values were not utilized in any treatment protocol or therapeutic decision. An independent t-test was used for statistical analysis. Results Our data demonstrate the feasibility of both technologies to measure cerebral oxygen saturation during CPR. With the continuous, pulseless near-infrared wave analysis of both FORE-SIGHT™ and EQUANOX™ technology, we obtained SctO2 values in the absence of spontaneous circulation. Both technologies were able to assess the efficacy of CPR efforts: improved resuscitation efforts (improved quality of chest compressions with switch of caregivers) resulted in higher SctO2 values. Until now, the ability of CPR to provide adequate tissue oxygenation was difficult to quantify or to assess clinically due to a lack of specific technology. With both technologies, any change in hemodynamics (for example, ventricular fibrillation) results in a reciprocal change in SctO2. In some patients, a sudden drop in SctO2 was the first warning sign of reoccurring ventricular fibrillation. Conclusions Both the FORE-SIGHT™ and EQUANOX™ technology allow non-invasive monitoring of the cerebral oxygen saturation during CPR

    Photodynamic therapy (PDT) was performed on 11 cases of recurrent cerebral glioma, including 3 cases of recurrent glioblastoma, 7 of recurrent anaplastic astrocytoma, and 1 recurrent ependymoma. Hematoporphyrin derivative (HPD) was administered intravenously at a dose of 4 - 7 mg/kg 5 - 24 hours before the operation. All patients underwent a craniotomy with a nearly radical excision of the tumor following which the tumor bed was irradiated with 630 nm laser light emitting either an argon pumped dye laser or frequency double YAG pumped dye laser for 30 to 80 minutes with a total dose of 50 J/cm2 (n equals 1), 100 J/cm2 (n equals 2), 200 J/cm2 (n equals 7), and 300 J/cm2 (n equals 1). The temperature was kept below 37 degree(s)C by irrigation. Two patients underwent postoperative radiotherapy. There was no evidence of increased cerebral edema, and no other toxicity by the therapy. All patients were discharged from the hospital within 15 days after surgery. We conclude that PDT using 4 - 7 mg/kg of HPD and 630 nm light with a dose of up to 300 J/cm2 can be used as an adjuvant therapy with no additional complications. Adjuvant PDT in the treatment of recurrent glioma is better than simple surgery.

    Summary Arterial fenestrations are an anatomic variant with indeterminate significance. Given the controversy surrounding fenestrations we sought their prevalence within our practice along with their association with other cerebrovascular anomalies. We retrospectively reviewed 10,927 patients undergoing digital subtraction angiography between 1992 and 2011. Dictated reports were searched for the terms “fenestration” or “fenestrated” with images reviewed for relevance, yielding 228 unique cases. A Medline database search from February 1964 to January 2013 generated 304 citations, 127 cases of which were selected for analysis. Cerebral arterial fenestrations were identified in 228 patients (2.1%). At least one aneurysm was noted in 60.5% of patients, with an aneurysm arising from the fenestration in 19.6% of patients. Aneurysmal subarachnoid hemorrhage or non-aneurysmal subarachnoid hemorrhage were present in 60.1% and 15.8%, respectively. For the subset of patients with an aneurysm arising directly from a fenestration relative to those patients with an aneurysm not immediately associated with a fenestration, the prevalence of aneurysmal subarachnoid hemorrhage was 66.7% vs. 58.6% (p = 0.58). Fenestrations were more often within the posterior circulation (73.2%) than the anterior circulation (24.6%), though there was no difference in the prevalence of aneurysms within these groups (61.1% vs. 60.7%, p = 1.0). Cerebral arterial fenestrations are an anatomic variant more often manifesting at the anterior communicating arterial complex and basilar artery and with no definite pathological relationship with aneurysms.

    Hospital diversification and its impact on the operating ratio are studied for 168 hospitals during the period from 1999 to 2004. Diversification and the operating ratio are modeled in a two-stage least squares (TSLS) framework as being jointly dependent. Institutional diversification is found to yield a better financial position, and the better operating ratio allows the institution the wherewithal to diversify. The impact of external government planning and hospital competition are also measured. An institution lifecycle hypothesis is advanced to explain hospital behavior: boom and bust, diversification and divestiture, occasionally leading to closure or merger. Management's attitude concerning risk and reward is considered.

    Abstract The aim of the study is to identify the potential risk factors of cerebral infarction associated with thoracic endovascular aneurysm repair (TEVAR). TEVAR was developed as a less invasive surgical alternative to conventional open repair for thoracic aortic aneurysm treatment. However, outcomes following TEVAR of aortic and distal arch aneurysms remain suboptimal. Cerebral infarction is a major concern during the perioperative period. We included 439 patients who underwent TEVAR of aortic aneurysms at a high-volume teaching hospital between July 2006 and June 2013. Univariate and multivariate logistic regression analyses were performed to identify perioperative cerebral infarction risk factors. Four patients (0.9%) died within 30 days of TEVAR; 17 (3.9%) developed cerebral infarction. In univariate analysis, history of ischemic heart disease and cerebral infarction and concomitant cerebrovascular disease were significantly associated with cerebral infarction. “Shaggy aorta” presence, left subclavian artery coverage, carotid artery debranching, and pull-through wire use were identified as independent risk factors of cerebral infarction. In multivariate analysis, history of ischemic heart disease (odds ratio [OR] 6.49, P = 0.046) and cerebral infarction (OR 43.74, P = 0.031), “shaggy aorta” (OR 30.32, P < 0.001), pull-through wire use during surgery (OR 7.196, P = 0.014), and intraoperative blood loss ≥800 mL (OR 24.31, P = 0.017) were found to be independent risk factors of cerebral infarction. This study identified patient- and procedure-related risk factors of cerebral infarction following TEVAR. These results indicate that patient outcomes could be improved through the identification and management of procedure-related risk factors. PMID:27082585

    Tacrolimus and mycophenolate mofetil are immunosuppressants frequently used in human organ transplantation. Tacrolimus is also reported to inhibit Plasmodium falciparum growth in vitro. Here, we report that tacrolimus prevented the death from cerebral malaria of Plasmodium berghei ANKA-infected C57BL/6J mice, but not their death from malaria due to the high parasitaemia and severe anaemia. The mycophenolate mofetil-treated mice showed higher mortality from cerebral malaria and succumbed to malaria earlier than tacrolimus-treated littermates. Tacrolimus attenuated the infiltration of mononuclear cells including pathogenic CD8(+) T cells into the brain. It appears to prevent murine cerebral malaria through the inhibition of cerebral infiltration of CD8(+) T cells. © 2016 John Wiley & Sons Ltd.

    A diagnosis of paradoxical cerebral embolus (PCE) was made in five patients aged 31 to 62 years who sustained eight cerebral ischemic events. No patient had evidence of primary carotid system or left heart disease. A probe-patent foramen ovale was the presumed mechanism in four patients, and an unsuspected congenital atrial septal defect was found in the fifth patient. Clinically apparent pulmonary emboli or venous thrombosis preceded the cerebral event in only one instance. Review of the literature reveals a high mortality with PCE. However, careful clinical search for this lesion may be rewarding: four of our five patients survived. One should consider PCE in any patient with cerebral embolus in whom there is no demonstrable left-sided circulatory source. This principle applies particularly if there is concomitant venous thrombosis, pulmonary embolism, or enhanced potential for venous thrombosis due to, for example, morbid obesity, use of hormonal birth control pills, prolonged bed rest (especially postoperatively), or systemic carcinoma.

    We have presented recommendations for diagnosis and management of otitis media in children based on a comprehensive review of the pertinent medical literature. For an entity that is so common, there still remain amazingly large numbers of areas of controversy. We have also attempted to stress the importance of appropriate therapy and adequate followup as being very important in the management of otitis media. Newer concepts, particularly the use of the impedance bridge tympanogram, have been mentioned. With all the above background information in mind and with considerations for what is practical for the patient and the medical community, we would recommend the following as the acceptable minimal care for patients with otitis media. When the diagnosis of the acute otitis media is made on the basis of physical findings of myringitis, and/or middle ear fluid, and/or rupture of the tympanic membrane, the following treatment course is advisable: Neonates Culture of middle ear fluid if possible. Ampicillin 200 mg/kg/day intramuscularly. Gentamicin 3/5mg/kg/day intramuscularly. Hospitalize and treat until well and for minimum of seven days. Observe closely for meningitis and other infections and drug toxicity. These should be handled only by physicians experienced in dealing with patients in this age range. Appropriate work-up for septicemia should precede treatment. Switch to specific antibiotic when cultures and sensitivity available. Children. From 2 months to 6 years of age: Ampicillin 50mg/kg/day. Decongestant (if desired). Administer for ten days. Every patient with otorrhea, severe otitis and those not clinically well should be seen for followup ten to 14 days later. They should have a minimum of otologic evaluation including drum mobility. In persistent cases, audiometry and otologic referral are necessary. If patient is allergic to penicillin, erythromycin at 20mg/lb/day may be used. Trimethoprim sulfa may hold promise in the future. Tetracycline is never

    Reversible cerebral vasoconstriction syndrome is characterized by thunderclap headache and diffuse segmental vasoconstriction that resolves spontaneously within 3 months. Previous reports have proposed that vasoconstriction first involves small distal arteries and then progresses toward major vessels at the time of thunderclap headache remission. The purpose of this study was to confirm centripetal propagation of vasoconstriction on MRA at the time of thunderclap headache remission compared with MRA at the time of reversible cerebral vasoconstriction syndrome onset. Of the 39 patients diagnosed with reversible cerebral vasoconstriction syndrome at our hospital during the study period, participants comprised the 16 patients who underwent MR imaging, including MRA, within 72 hours of reversible cerebral vasoconstriction syndrome onset (initial MRA) and within 48 hours of thunderclap headache remission. In 14 of the 16 patients (87.5%), centripetal propagation of vasoconstriction occurred from the initial MRA to remission of thunderclap headache, with typical segmental vasoconstriction of major vessels. These mainly involved the M1 portion of the MCA (10 cases), P1 portion of the posterior cerebral artery (10 cases), and A1 portion of the anterior cerebral artery (5 cases). This study found evidence of centripetal propagation of vasoconstriction on MRA obtained at the time of thunderclap headache remission, compared with MRA obtained at the time of reversible cerebral vasoconstriction syndrome onset. If clinicians remain unsure of the diagnosis during early-stage reversible cerebral vasoconstriction syndrome, this time point represents the best opportunity to diagnose reversible cerebral vasoconstriction syndrome with confidence. © 2016 by American Journal of Neuroradiology.

  10. Catatonia After Cerebral Hypoxia: Do the Usual Treatments Apply?

    2014-01-01

    Introduction Neurologic deterioration occurring days to weeks after a cerebral hypoxic event accompanied by diffuse white matter demyelination is called delayed post-hypoxic leukoencephalopathy (DPHL). Manifestations of DPHL are diverse, and include dementia, gait disturbance, incontinence, pyramidal tract signs, parkinsonism, chorea, mood and thought disorders, akinetic mutism, and rarely catatonia. Methods The authors report a case of malignant catatonia in a patient diagnosed with DPHL that was refractory to electroconvulsive therapy (ECT), and review the literature on catatonia in DHPL. Results The patient was a 56 year-old female with schizoaffective disorder who was admitted with catatonia two weeks after hospitalization for drug overdose and respiratory failure. Her catatonic symptoms did not respond to lorazepam, amantadine, methylphenidate, or ten sessions of bilateral ECT at maximum energy. Repeat magnetic resonance imaging revealed extensive periventricular white matter lesions not present on admission scans, and she was diagnosed with DPHL. Discussion No treatment for DPHL has been proven to be widely effective. Hyperbaric oxygen treatments may reduce the rate of development, and symptom improvement has been reported with stimulants and other psychotropic agents. Review of the literature reveals rare success with GABAergic agents for catatonia after cerebral hypoxia, and no cases successfully treated with ECT. There are seven case reports of neurologic decompensation during ECT treatment after a cerebral hypoxic event. Conclusion Caution is advised when considering ECT for catatonia when delayed sequelae of cerebral hypoxia are on the differential diagnosis, as there is a dearth of evidence to support this treatment approach.

    From a pair of parietal electrodes, an original apparatus--the monitor of cerebral function--gives a non-stop recording of the brain electric activity for frequencies ranging from 2 to 15 Hertz. It is at the moment less expensive than an ordinary EEG apparatus, easy to carry, to use and to read. The artefacts, interferences or technical defects are either totally eliminated or immediately detected thanks to a parallel graph. It is the first apparatus that has been conceived and used as a routine instrument for cerebral monitoring. It can be used in the Intensive Care Unit as well as in the Operating Theatre:--preventively, whenever there is a risk of an alteration in the cerebral circulation (CEC - extracorporal circulation - for instance - as a diagnosis, a prognosis or a therapy when there is a cerebral lesion (whatever the origin of it can be). The use of this apparatus (that has now become part of the daily routine at the London Hospital) has quickly proved indispensable and the common EEG is no longer being resorted to except upon very few occasions.

    The purpose of this investigation was to describe the causes, clinical pattern, and treatment of cerebral salt wasting syndrome in children with acute central nervous system injury. This retrospective study focused on patientscerebral salt wasting syndrome, over a period of 7 years, in the pediatric intensive care unit of a tertiary care hospital. Selection criteria included evidence of hyponatremia (serum sodium<130 mEq/L), polyuria, elevated urine sodium (>120 mEq/L), and volume depletion. Fourteen patients were identified with cerebral salt wasting syndrome, 12 after a neurosurgical procedure (8 brain tumor, 4 hydrocephalus) and 2 after severe brain trauma. In 11 patients the cerebral salt wasting syndrome was diagnosed during the first 48 hours of admission. Prevalence of cerebral salt wasting syndrome in neurosurgical children was 11.3/1000 surgical procedures. The minimum sodium was 122+/-7 mEq/L, the maximum urine osmolarity 644+/-59 mOsm/kgH2O. The maximum sodium supply was 1 mEq/kg/h (range, 0.1-2.4). The mean duration of cerebral salt wasting syndrome was 6+/-5 days (range 1-9). In conclusion, cerebral salt wasting syndrome can complicate the postoperative course of children with brain injury; it is frequently present after surgery for brain tumors and hydrocephalus and in patients with severe head trauma. Close monitoring of salt and fluid balance is essential to prevent severe neurologic and hemodynamic complications.

    A case of accessory middle cerebral artery associated with internal carotid artery aneurysm was reported. A 50-year-old female was admitted to our hospital with complaints of headache, nausea, vomiting and conciousness disturbance. Lumbar puncture showed bloody CSF. Right carotid angiogram revealed saccular aneurysm of the internal carotid-posterior communicating artery and accessory middle cerebral artery originating from the horizontal portion of the right anterior cerebral artery. No other vascular lesion was observed on other angiograms. Operation was performed 2 days after admission. The neck of the aneurysm was clipped. Postoperative aseptic meningitis was cured by frequent lumbar punctures, and her course was uneventful. The etiological hypothesis of these cerebral vascular anomalies was briefly discussed.

  17. Therapeutic implications of melatonin in cerebral edema.

    Cerebral edema/brain edema refers to the accumulation of fluid in the brain and is one of the fatal conditions that require immediate medical attention. Cerebral edema develops as a consequence of cerebral trauma, cerebral infarction, hemorrhages, abscess, tumor, hypoxia, and other toxic or metabolic factors. Based on the causative factors cerebral edema is differentiated into cytotoxic cerebral edema, vasogenic cerebral edema, osmotic and interstitial cerebral edema. Treatment of cerebral edema depends on timely diagnosis and medical assistance. Pragmatic treatment strategies such as antihypertensive medications, nonsteroidal anti-inflammatory drugs, barbiturates, steroids, glutamate and N-methyl-D-aspartate receptor antagonists and trometamol are used in clinical practice. Although the above mentioned treatment approaches are being used, owing to the complexity of the mechanisms involved in cerebral edema, a single therapeutic strategy which could ameliorate cerebral edema is yet to be identified. However, recent experimental studies have suggested that melatonin, a neurohormone produced by the pineal gland, could be an effective alternative for treating cerebral edema. In animal models of stroke, melatonin was not only shown to reduce cerebral edema but also preserved the blood brain barrier. Melatonin's beneficial effects were attributed to its properties, such as being a potent anti-oxidant, and its ability to cross the blood brain barrier within minutes after its administration. This review summarizes the beneficial effects of melatonin when used for treating cerebral edema.

    Cerebral oxygenation is not always reflected by systemic arterial oxygenation. Therefore, regional cerebral oxygen saturation (rScO2) monitoring with near-infrared spectroscopy (NIRS) is of added value in neonatal intensive care. rScO2 represents oxygen supply to the brain, while cerebral fractional tissue oxygen extraction, which is the ratio between rScO2 and systemic arterial oxygen saturation, reflects cerebral oxygen utilization. The balance between oxygen supply and utilization provides insight in neonatal cerebral (patho-)physiology. This review highlights the potential and limitations of cerebral oxygenation monitoring with NIRS in the neonatal intensive care unit. PMID:28352624

    Under the current system, orthopaedic trauma surgeons must work in some form of hospital setting as our primary service involves treatment of the trauma patient. We must not forget that just as a trauma center cannot exist without our services, we cannot function without their support. As a result, a clear understanding of the balance between physicians and hospitals is paramount. Historical perspective enables physicians and hospital personnel alike to understand the evolution of hospital-physician relationship. This process should be understood upon completion of this chapter. The relationship between physicians and hospitals is becoming increasingly complex and multiple forms of integration exist such as joint ventures, gain sharing, and co-management agreements. For the surgeon to negotiate well, an understanding of hospital governance and the role of the orthopaedic traumatologist is vital to success. An understanding of the value provided by the traumatologist includes all aspects of care including efficiency, availability, cost effectiveness, and research activities. To create effective and sustainable healthcare institutions, physicians and hospitals must be aligned over a sustained period of time. Unfortunately, external forces have eroded the historical basis for the working relationship between physicians and hospitals. Increased competition and reimbursement cuts, coupled with the increasing demands for quality, efficiency, and coordination and the payment changes outlined in healthcare reform, have left many organizations wondering how to best rebuild the relationship. The principal goal for the physician when partnering with a hospital or healthcare entity is to establish a sustainable model of service line management that protects or advances the physician's ability to make impactful improvements in quality of patient care, decreases in healthcare costs, and improvements in process efficiency through evidence-based practices and protocols.

  10. Encephaloduroarteriosynangiosis for cerebral proliferative angiopathy with cerebral ischemia.

    PubMed

    Kono, Kenichi; Terada, Tomoaki

    2014-12-01

    Cerebral proliferative angiopathy (CPA) is a rare clinical entity. This disorder is characterized by diffuse vascular abnormalities with intermingled normal brain parenchyma, and is differentiated from classic arteriovenous malformations. The management of CPA in patients presenting with nonhemorrhagic neurological deficits due to cerebral ischemia is challenging and controversial. The authors report a case of adult CPA with cerebral ischemia in which neurological deficits were improved after encephaloduroarteriosynangiosis (EDAS). A 28-year-old man presented with epilepsy. Magnetic resonance imaging and angiography showed a diffuse vascular network (CPA) in the right hemisphere. Antiepileptic medications were administered. Four years after the initial onset of epilepsy, the patient's left-hand grip strength gradually decreased over the course of 1 year. The MRI studies showed no infarcts, but technetium-99m-labeled ethyl cysteinate dimer ((99m)Tc-ECD) SPECT studies obtained with acetazolamide challenge demonstrated hypoperfusion and severely impaired cerebrovascular reactivity over the affected hemisphere. This suggested that the patient's neurological deficits were associated with cerebral ischemia. The authors performed EDAS for cerebral ischemia, and the patient's hand grip strength gradually improved after the operation. Follow-up angiography studies obtained 7 months after the operation showed profound neovascularization through the superficial temporal artery and the middle meningeal artery. A SPECT study showed slight improvement of hypoperfusion at the focal region around the right motor area, indicating clinical improvement from the operation. The authors conclude that EDAS may be a treatment option for CPA-related hypoperfusion.

  11. Cerebral palsy update.

    2009-08-01

    A common language on CP has been developed for the European registers by the SCPE (Surveillance of Cerebral Palsy in Europe) working group and the common database allows prevalence analyses on a larger basis. CP prevalence increases with lower birthweight and higher immaturity. Increase of survival after preterm birth has first also increased CP rates. But already in the 80s this trend was reversed for LBW infants, and in the 90 s also for VLBW or very immature infants. The outcome with respect to CP in the group of extremely LBW or immature infants remains a matter of specific concern, as prevalence seems to be rather stable on a high level. CP is caused in more than 80% by brain lesions or maldevelopments which can be attributed to different timing periods of the developing brain. Extent and topography determine the clinical subtype of CP and are related also to the presence and severity of associated disabilities. CP, thus, offers a model to study plasticity of the developing brain. Reorganisation following unilateral lesions is mainly interhemispheric and homotopic. In the motor system, it involves the recruitment of ipsilateral tracts; functionality seems to be limited and decreases already towards the end of gestation. There is no clear evidence for substantial reorganisation in the sensory system. The best compensatory potential is described concerning language function following left hemispheric lesions. Language function reorganized to the right hemisphere eventually seems not to be impaired, this occurs, however, on the expense of primary right hemispheric functions.

  12. Cerebral amyloid angiopathy.

    PubMed

    Yamada, Masahito; Naiki, Hironobu

    2012-01-01

    Cerebral amyloid angiopathy (CAA) is cerebrovascular amyloid deposition. It is classified into several types according to the cerebrovascular amyloid proteins involved [amyloid β-protein (Aβ), cystatin C (ACys), prion protein (APrP), transthyretin (ATTR), gelsolin (AGel), ABri/ADan, and AL]. Sporadic Aβ-type CAA is commonly found in elderly individuals and patients with Alzheimer's disease (AD). CAA-related disorders include hemorrhagic and ischemic brain lesions and dementia. It has been proposed that cerebrovascular Aβ originates mainly from the brain and is transported to the vascular wall through a perivascular drainage pathway, where it polymerizes into fibrils on vascular basement membrane through interactions with extracellular components. CAA would be promoted by overproduction of Aβ40 (a major molecular species of cerebrovascular Aβ), a decrease of Aβ degradation, or reduction of Aβ clearance due to impairment of perivascular drainage pathway. Further understanding of the molecular pathogenesis of CAA would lead to development of disease-modifying therapies for CAA and CAA-related disorders. Copyright © 2012 Elsevier Inc.

  13. [Plasma osmolarity and cerebral volume].

    PubMed

    Boulard, G

    2001-02-01

    Under normal physiological conditions, the osmolarity of extracellular fluids (ECFs) and natremia are controlled by two regulatory mechanisms modulating the water balance and sodium outflow from information collected by the osmoreceptors and baroreceptors, respectively. As well, under normal physiological conditions, water and electrolytes of brain ECFs are secreted by the endothelial cells of brain capillaries. Furthermore, isotonicity is present on both sides of the blood-brain barrier. In the event of systemic osmolarity disorders, water transport subject to osmosis laws occurs at the level of the blood-brain barrier. In the case of plasmatic hyperosmolarity cerebral dehydration is observed, while cerebral edema occurs in the contrary case. However, plasmatic osmolarity disorders have less effect on the cerebral volume when their introduction is slow. Experimentation in acute conditions shows that measured variations of the cerebral water content are lower than calculated variations, thus suggesting the existence of an adaptive mechanism, that is, the cerebral osmoregulation which limits the variation of the volume of brain cells by modulating their osmoactive molecule content. These osmoactive molecules are, on the one hand, the electrolytes, which are early and rapidly mobilized, and, on the other hand, the organic osmoles (amino acids, etc.), whose secretion is slower and delayed. This phenomenon should be taken into account in the treatment of osmolarity disorders. Thus, the related-risk of treatment for natremia disorders is therapeutic reversal of the osmotic gradient at the level of the blood-brain barrier. This reversal, which corresponds to a second osmotic stress, requires the implementation of a new procedure of cerebral osmoregulation in the opposite direction of the preceding one. As successive osmotic stresses decrease the effectiveness of brain osmoregulation, the risk for cerebral dehydration and pontine myelinolysis increases when the treatment

    This paper deals with cerebral paragonimiasis and cerebral hemispherectomy conducted as a treatment of cerebral paragonimiasis by Bo Sung Sim in Korea in 1950s-1960s. He demonstrated that cerebral hemispherectomy could be used for unilateral diffuse cerebral paragonimiasis. Sim learned cerebral hemispherectomy from Dr. L. A. French. at the University of Minnesota from 1955 to 1957 in America. The authors argues that Bo Sung Sim's introduction of cerebral hemispherectomy to Korea was not a simple application of an advanced medical technology, but a complicated and active process in that Sim used the technique to intervene intractable complications from cerebral paragonimiasis such as generalized convulsions, spastic hemiplegia and mental deterioration. Bo Sung Sim, one of the neurosurgeons of the first generation in Korea, was trained in neurology, neuropathology, neuroradiology and animal experiments as well as in neurosurgery at the University of Minnesota. After returning to Korea, Sim faced parasitic diseases, one of the most serious public health problems at that time, which were far different from what he learned in America. As a neurosurgeon, Sim tackled with parasitic diseases of the central nervous system with various diagnostics and therapeutics. In 1950s, more than one million populations suffered from pulmonary paragonimiasis acquired by eating raw crabs or by feeding juice of crushed crayfish for the treatment of measles in Korea. About 26.6 percent of people with paragonimiasis had cerebral paragonimiasis. Before bithionol therapy was introduced in 1962, neurosurgery was the only available treatment to control increased intracranial pressures, intractable epilepsy, paralysis and mental deterioration. Between 1958 to 1962, Bo Sung Sim operated on 24 patients of cerebral paragonimiasis. In two of them, he performed cerebral hemispherectomy to control intractable convulsions when he found diffuse cerebral paragonimiasis and cerebral atrophy at the

    A 27-year-old woman was admitted to other hospital for acute pleuritis in May 1977. She suddenly had a focal epileptic seizure in the face with loss of consciousness on July 10, 1977. The same episodes of seizure occurred on Aug. 8, on Oct. 26, on Nov. 22, 1977. She was admitted to our hospital on Dec. 12, 1977. Neurological examinations showed no abnormality. Chest X-ray film showed bilateral severe thickening of the pleura. Plain skull films showed normal findings. Enhanced CT scanning showed a homogenous irregular contour of high density area surrounded by low density area in the right frontal region. The lateral ventricle was slightly shifted to the left side. 99mTc brain scan also detected a spherical abnormal uptake in this area. Right carotid angiography showed no abnormal vessels and increased vascularities. On Nov. 22, 1977, a craniotomy was made over the right fronto-temporal bone, and a walnut sized tumor in the frontal subcortex was totally removed successfully. Histologically, the tumor was diagnosed as brain tuberculoma. The antituberculous therapy (AB-PC, INAH, Rifampicin), high doses of gammabenin, and steroid were given. About four months later, she was in good health without neurologic deficits and returned to her work. The literature was reviewed, and the value of CT scan and RI scan in the diagnosis of cerebral tuberculoma was emphasized.

    Objective: To identify global research trends in neuroimaging diagnosis for cerebral infarction using a bibliometric analysis of the Web of Science. Data Retrieval: We performed a bibliometric analysis of data retrieval for neuroimaging diagnosis for cerebral infarction containing the key words “CT, magnetic resonance imaging, MRI, transcranial Doppler, transvaginal color Doppler, digital subtraction angiography, and cerebral infarction” using the Web of Science. Selection Criteria: Inclusion criteria were: (a) peer-reviewed articles on neuroimaging diagnosis for cerebral infarction which were published and indexed in the Web of Science; (b) original research articles and reviews; and (c) publication between 2004–2011. Exclusion criteria were: (a) articles that required manual searching or telephone access; and (b) corrected papers or book chapters. Main Outcome Measures: (1) Annual publication output; (2) distribution according to country; (3) distribution according to institution; (4) top cited publications; (5) distribution according to journals; and (6) comparison of study results on neuroimaging diagnosis for cerebral infarction. Results: Imaging has become the predominant method used in diagnosing cerebral infarction. The most frequently used clinical imaging methods were digital subtraction angiography, CT, MRI, and transcranial color Doppler examination. Digital subtraction angiography is used as the gold standard. However, it is a costly and time-consuming invasive diagnosis that requires some radiation exposure, and is poorly accepted by patients. As such, it is mostly adopted in interventional therapy in the clinic. CT is now accepted as a rapid, simple, and reliable non-invasive method for use in diagnosis of cerebrovascular disease and preoperative appraisal. Ultrasonic Doppler can be used to reflect the hardness of the vascular wall and the nature of the plaque more clearly than CT and MRI. Conclusion: At present, there is no unified standard of

    In recent years, patient selection for intravenous tissue plasminogen activator (t-PA) therapy based on clinical-diffusion mismatch (CDM) has been closely examined. We investigated the relationship between prognosis and CDM in patients with hyperacute cerebral infarction within 3 hours of onset and compared CDM with diffusion-perfusion mismatch (DPM). Of 122 patients with hyperacute cerebral infarction who visited the hospital within 3 hours of onset between April 2007 and November 2008, 85 patients with cerebral infarction in the anterior circulation who underwent head magnetic resonance imaging diffusion-weighted imaging (DWI)/magnetic resonance angiography (MRA) (51 men and 34 women; average age, 74 ± 10 years) were enrolled. Seventeen of these patients underwent CT perfusion imaging. CDM-positive cases were those with a National Institute of Health Stroke Scale (NIHSS) score ≥ 8 and a DWI-Alberta Stroke Program Early CT Score (DWI-ASPECTS) ≥ 8; CDM-negative cases were those with an NIHSS score ≥ 8 and an ASPECTS-DWI < 8. The other patients were classified as belonging to the NIHSS score < 8 group. Of the 32 CDM-positive cases, 10 received t-PA infusion. These patients had markedly higher modified Rankin Scale scores 90 days after onset compared with the 22 patients who did not receive t-PA infusion. The 8 CDM-positive cases included 4 DPM-positive cases and 4 DPM-negative cases, and a discrepancy was confirmed between CDM and DPM. In all DPM-positive cases, MRA confirmed lesions in major intracranial arteries. CDM may enable more accurate prediction of outcomes in patients with hyperacute cerebral infarction. In addition, the combination of CDM findings and MRA findings (stenosis or occlusion in major intracranial arteries) may be an alternative to DPM for determining the indications for IV t-PA therapy in patients with hyperacute cerebral infarction.

    To report on the effects of cardiopulmonary resuscitation (CPR) instituted immediately after a cardiac arrest on cerebral perfusion pressure (CPP) and cerebral tissue oxygen tension (PbrO(2)). Case report. ICU of a university hospital. A head-injured 17-year-old man submitted to multimodal neurological monitoring underwent sudden cardiac arrest and successful CPR. External chest compression, 100% oxygen ventilation, volume expansion and standard ACLS protocols. Heart rate, ECG, mean arterial blood pressure (MABP), ETCO(2), PaO(2), intracranial pressure (ICP), CPP and PbrO(2) were continuously monitored during CPR and data recorded at 15-s intervals by a dedicated personal computer. At the onset of the cardiac arrest, PbrO(2) decreased to zero. The institution of CPR resulted in a progressive increase of MABP, CPP and PbrO(2). Assuming, on the basis of previous experimental and clinical reports, 8 mmHg PbrO(2) as a possible ischaemic/hypoxic threshold value, during the first 6.5 min of CPR, PbrO(2) values were below this threshold (range 0-7 mmHg) and CPP values were <25 mmHg for 81.5% of the time. In the following 5.5 min, more efficient CPR generated CPP values >25 mmHg for 77.3% of the time. These values were associated with a PbrO(2) >8 mmHg (range 8-28 mmHg) at all times. In the clinical setting of a witnessed cardiac arrest, immediate institution of CPR can be effective in generating PbrO(2) values above a supposed ischaemic/hypoxic threshold when CPP is >25 mmHg. PbrO(2) monitoring by the Licox system is sensitive and reliable, even at low values, and can be suitable for evaluating cerebral oxygenation during experimental CPR.

  14. Reversible Cerebral Vasoconstriction Syndrome.

    PubMed

    Bernard, Kenneth R L; Rivera, Morris

    2015-07-01

    Reversible cerebral vasoconstriction syndrome (RCVS) is an underappreciated and poorly understood cause of thunderclap headache (TCH). Although self-limited in the majority of patients, incidence is increasing, with presentations overlapping considerably with life-threatening conditions, such as aneurysmal subarachnoid hemorrhage and stroke. In addition, radiographic findings seen in RCVS are also present in primary angiitis of the central nervous system (PACNS). Misdiagnosis of RCVS might subject patients to unnecessary invasive testing and immunosuppressive therapy. Furthermore, the recommended treatment of glucocorticoids used in PACNS can be harmful in RCVS. RCVS is not a benign condition, as patients can have ischemic or hemorrhagic complications leading to persistent neurologic deficits and even death. Current treatments, guided only by expert consensus, have no proven effect on these complications, which argues the need for accurate identification of patients with RCVS and prospective studies to validate treatment and inform prognoses. We describe a previously healthy male who presented to the emergency department after 2 episodes of TCH and angiography consistent with RCVS. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: RCVS is a common but underappreciated cause of TCH. The likelihood of misdiagnosing RCVS following the accepted diagnostic algorithm of acute headache in the emergency department is high due to a lack of clinical awareness and common features shared with other headache syndromes. Emergency department physicians must broaden the differential in patients presenting to the emergency department with TCH to include RCVS and be familiar with the accepted treatments and appropriate follow-up.

    Antegrade cerebral perfusion and hypothermic circulatory arrest, with or without retrograde cerebral perfusion, are 2 major types of brain protection that are used during aortic arch surgery. We conducted a comparative study of these methods in patients undergoing total arch replacement to evaluate the clinical outcomes in Japan, based on the Japan Adult Cardiovascular Surgery Database. A total of 16,218 patients underwent total arch replacement between 2009 and 2012. Patients with acute aortic dissection or ruptured aneurysm, or who underwent emergency surgery were excluded, leaving 8169 patients for analysis. For the brain protection method, 7038 patients had antegrade cerebral perfusion and 1141 patients had hypothermic circulatory arrest/retrograde cerebral perfusion. A nonmatched comparison was made between the 2 groups, and propensity score analysis was performed among 1141 patients. The matched paired analysis showed that the minimum rectal temperature was lower in the hypothermic circulatory arrest/retrograde cerebral perfusion group (21.2°C ± 3.7°C vs 24.2°C ± 3.2°C) and that the duration of cardiopulmonary bypass and cardiac ischemia was longer in the antegrade cerebral perfusion group. There were no significant differences between the antegrade cerebral perfusion and hypothermic circulatory arrest/retrograde cerebral perfusion groups with regard to 30-day mortality (3.2% vs 4.0%), hospital mortality (6.0% vs 7.1%), incidence of stroke (6.7% vs 8.6%), or transient neurologic disorder (4.1% vs 4.4%). There was no difference in a composite outcome of hospital death, bleeding, prolonged ventilation, need for dialysis, stroke, and infection (antegrade cerebral perfusion 28.4% vs hypothermic circulatory arrest 30.1%). However, hypothermic circulatory arrest/retrograde cerebral perfusion resulted in a significantly higher rate of prolonged stay in the intensive care unit (>8 days: 24.2% vs 15.6%).

    Social media use is expanding rapidly, so too is its use within hospitals and amongst healthcare professionals. This study describes the use of social media by Australian and New Zealand nursing and midwifery graduates of the Graduate e-Cohort study; there were 112 (93%) respondents from a 2014 sample of 121 nurses and midwives. Findings suggest that the professional peak body goal of using social media as a vehicle for professional education requires consideration of the social media platforms that are actually being used by new graduates. We recommend that work by the respective professions at both an undergraduate and graduate level needs to focus on the implications of social media use or policy and practice to ensure that everyone is aware of when and how to engage in social media platforms and what to do and how to behave when using social media.

    Reversible cerebral constriction syndrome and cerebral venous thrombosis are two rare conditions. Reversible cerebral constriction syndrome affects the cerebral arteries and the pathology is still largely unknown. To date, no physiological link with cerebral venous thrombosis has been reported. We report here the case of a 24-year-old woman who presented a reversible cerebral constriction syndrome in the setting of a cerebral venous thrombosis. Cerebral venous thrombosis had developed in her left lateral venous sinus, within the stent placed one year before, in order to treat an idiopathic intracranial hypertension. The co-occurrence of cerebral venous thrombosis and reversible cerebral constriction syndrome in the same patient raises the issue of a potential link between them. We discuss the potential common trigger factors in this case: recent hormonal therapy; intracranial hypotension iatrogenically induced by lumbar puncture. © International Headache Society 2015.

    DRESS (drug rash with eosinophilia and systemic symptoms) syndrome is a severe reaction triggered by drugs that manifests as pyrexia and eosinophilia with involvement of the skin and internal organs. We herein describe the case of a patient who developed hyperuricemia after receiving treatment for tuberculosis, then took allpurinol and developed DRESS syndrome with a contextual coma and right hemisyndrome. This report describes for the first time the presence of vasculitic cerebral involvement in a patient with DRESS syndrome. The cerebral vasculitis responded to treatment, showing clinical and instrumental remission. In cases such as this, allergic cerebral vasculitis should be considered in the differential diagnosis because it can be treated if recognized early, thus leading to remission without the development of any sequelae.

    Assisted reproductive technologies have been widely used over the past 30 years, and 1% to 4% of births worldwide are products of these technologies. However, adverse health outcomes related to assisted reproductive technologies, including cerebral palsy, have been reported. We extracted and reviewed all relevant studies cited by Medline from 1996 to 2010 evaluating the role of assisted reproductive technologies as a causative factor for cerebral palsy and poor long-term neurologic outcome. The research suggests that multiple pregnancy, preterm delivery, and babies small for gestational age are factors in the development of cerebral palsy. The vanishing embryo syndrome may also play a role. We review the evidence for these potentially causative factors, as well as their implications for embryo transfer policies.

    Cerebral abscess is a rare but serious and life-threatening infection. Dental infections have occasionally been reported as the source of bacteria for such an abcess. A 54-year-old man was admitted with a right hemiparesis and epileptic fits. After clinical, laboratory and imaging examination, the diagnosis of a cerebral abscess of the left parietal lobe was made. The intraoral clinical examination as well as a panoramic radiograph confirmed the presence of generalized periodontal disease, multiple dental caries, and periapical pathology. The treatment included: (i) Immediate administration of high-dose intravenous antibiotics and (ii) surgical procedures consisting of craniotomy and resection of the abscess cavity first, and secondly removal of the periodontal, decayed and periapically involved teeth of the patient, in an effort to eradicate all the possible septic foci, presuming the cerebral abscess to be of odontogenic infection. The patient made an uneventful recovery, and 29 months postoperatively he had completely recovered from the hemiparesis.

  1. Changes in cerebral oxygen saturation during transcatheter aortic valve replacement.

    2016-10-01

    Cerebral oxygen saturation (rSO2) is a non-invasive monitor used to monitor cerebral oxygen balance and perfusion. Decreases in rSO2 >20 % from baseline have been associated with cerebral ischemia and increased perioperative morbidity. During transcatheter aortic valve replacement (TAVR), hemodynamic manipulation with ventricular pacing up to 180 beats per minute is necessary for valve deployment. The magnitude and duration of rSO2 change during this manipulation is unclear. In this small case series, changes in rSO2 in patients undergoing TAVR are investigated. Ten ASA IV patients undergoing TAVR with general anesthesia at a university hospital were prospectively observed. Cerebral oximetry values were analyzed at four points: pre-procedure (baseline), after tracheal intubation, during valve deployment, and at procedure end. Baseline rSO2 values were 54.5 ± 6.9 %. After induction of general anesthesia, rSO2 increased to a mean of 66.0 ± 6.7 %. During valve deployment, the mean rSO2 decreased <20 % below baseline to 48.5 ± 13.4 %. In two patients, rSO2 decreased >20 % of baseline. Cerebral oxygenation returned to post-induction values in all patients 13 ± 10 min after valve deployment. At procedure end, the mean rSO2 was 67.6 ± 8.1 %. As expected, rapid ventricular pacing resulting in the desired decrease in cardiac output during valve deployment was associated with a significant decrease in rSO2 compared to post-induction values. However, despite increased post-induction values in all patients, whether related to increased inspired oxygen fraction or reduced cerebral oxygen consumption under anesthesia, two patients experienced a significant decrease in rSO2 compared to baseline. Recovery to baseline was not immediate, and took up to 20 min in three patients. Furthermore, baseline rSO2 in this population was at the lower limit of the published normal range. Significant cerebral desaturation during valve deployment may potentially be limited

    Diabetic ketoacidosis (DKA) may cause brain injuries in children. The mechanisms responsible are difficult to elucidate because DKA involves multiple metabolic derangements. We aimed to determine the independent effects of hyperglycemia and ketosis on cerebral metabolism, blood flow, and water distribution. We used magnetic resonance spectroscopy to measure ratios of cerebral metabolites (ATP to inorganic phosphate [Pi], phosphocreatine [PCr] to Pi, N-acetyl aspartate [NAA] to creatine [Cr], and lactate to Cr) and diffusion-weighted imaging and perfusion-weighted imaging to assess cerebral water distribution (apparent diffusion coefficient [ADC] values) and cerebral blood flow (CBF) in three groups of juvenile rats (hyperglycemic, ketotic, and normal control). ATP-to-Pi ratio was reduced in both hyperglycemic and ketotic rats in comparison with controls. PCr-to-Pi ratio was reduced in the ketotic group, and there was a trend toward reduction in the hyperglycemic group. No significant differences were observed in NAA-to-Cr or lactate-to-Cr ratio. Cortical ADC was reduced in both groups (indicating brain cell swelling). Cortical CBF was also reduced in both groups. We conclude that both hyperglycemia and ketosis independently cause reductions in cerebral high-energy phosphates, CBF, and cortical ADC values. These effects may play a role in the pathophysiology of DKA-related brain injury. PMID:22498698

    2008-11-01

    Pituitary apoplexy is a potentially fatal condition that can have serious consequences even after successful treatment. One of the potential complications of this syndrome is occlusion of the internal carotid arteries, which causes cerebral ischaemia. This can occur through one of two mechanisms--direct compression of the artery or vasospasm caused by factors released from haemorrhagic or necrotic material. We illustrate two examples of cerebral ischaemia with pituitary apoplexy, one with compression and one with vasospasm, both ending in a successful resolution. In both, magnetic resonance imaging, angiography, and hormonal studies allow diagnosis, and urgent surgical decompression should be the treatment of choice. We review the literature and discuss the mechanisms.

    Neurotoxoplasmosis (NT) sometimes manifests unusual characteristics. We analyzed 85 patients with NT and AIDS according to clinical, cerebrospinal fluid, cranial magnetic resonance, and polymerase chain reaction (PCR) characteristics. In 8.5%, focal neurological deficits were absent and 16.4% had single cerebral lesions. Increased sensitivity of PCR for Toxoplasma gondii DNA in the central nervous system was associated with pleocytosis and presence of >4 encephalic lesions. Patients with NT may present without focal neurological deficit and NT may occur with presence of a single cerebral lesion. Greater numbers of lesions and greater cellularity in cerebrospinal fluid improve the sensitivity of PCR to T gondii.

    Single cerebral toxoplasmic lesions are rarely explored. Through magnetic resonance imaging, 10 lesions were analyzed regarding location, signal intensity, contrast enhancement, eccentric target, and meningeal uptake. Five lesions were corticosubcortical and in the deep three (60%) had infratentorial locations. Iso- or hypointense signal predominated in T1 sequence, but in T2, there was variability. Perilesional edema and ring contrast enhancement occurred in 100% of lesions, but eccentric targets and meningeal uptake were less frequent. Even in the presence of single lesions, iso- or hypointense signal in T1, perilesional edema, and ring enhancement are suggestive of cerebral toxoplasmosis. Crown Copyright © 2012.

    ABSTRACT Special and medically compromised patients present a unique population that challenges the dentist’s skill and knowledge. Providing oral care to people with cerebral palsy (CP) requires adaptation of the skills we use everyday. In fact, most people with mild or moderate forms of CP can be treated successfully in the general practice setting. This article is to review various dental considerations and management of a CP patient. How to cite this article: Sehrawat N, Marwaha M, Bansal K, Chopra R. Cerebral Palsy: A Dental Update.

    Social media has increasingly changed the landscape of medicine and surgery and is rapidly expanding its influence in most peoples' lives. The average person spends nearly 2 hours per day using social media, consuming information about everything from family updates to entertainment news to presidential elections. The concentration of consumers on social media platforms has resulted in direct medicine and medical products marketing to consumers. Similarly, social media is increasingly becoming a platform for interaction between physicians and potential patients. Some physicians have taken this opportunity to better educate patients, while allowing patients to learn more about their surgeons online. These tools can increase internet traffic online to bonafide internet sites, as well as bolster marketing for many hospitals, hospital systems, and individual doctors. It can also serve to increase knowledge about procedures and conditions through direct outreach to patients. Social media is a powerful tool which needs to be utilized wisely to avoid pitfalls.

    Cerebral microbleeds (CMBs) are collections of blood breakdown products that are a common incidental finding in magnetic resonance imaging of elderly individuals. Cerebral microbleeds are associated with cognitive deficits, but the mechanism is unclear. Studies show that individuals with CMBs related to symptomatic cerebral amyloid angiopathy have abnormal vascular reactivity and cerebral blood flow (CBF), but, to our knowledge, abnormalities in cerebral blood flow have not been reported for healthy individuals with incidental CMBs. To evaluate the association of incidental CMBs with resting-state CBF, cerebral metabolism, cerebrovascular disease, β-amyloid (Aβ), and cognition. A cross-sectional study of 55 cognitively normal individuals with a mean (SD) age of 86.8 (2.7) years was conducted from May 1, 2010, to May 1, 2013, in an academic medical center in Pittsburgh; data analysis was performed between June 10, 2013, and April 9, 2015. 3-Tesla magnetic resonance imaging was performed with susceptibility-weighted imaging or gradient-recalled echo to assess CMBs, arterial spin labeling for CBF, and T1- and T2-weighted imaging for atrophy, white matter hyperintensities, and infarcts. Positron emission tomography was conducted with fluorodeoxyglucose to measure cerebral metabolism and Pittsburgh compound B for fibrillar Aβ. Neuropsychological evaluation, including the Clinical Dementia Rating scale, was performed. Magnetic resonance images were rated for the presence and location of CMBs. Lobar CMBs were subclassified as cortical or subcortical. Measurements of CBF, metabolism, and Aβ were compared with the presence and number of CMBs with voxelwise and region-of-interest analyses. The presence of cortical CMBs was associated with significantly reduced CBF in multiple regions on voxelwise and region-of-interest analyses (percentage difference in global CBF, -25.3%; P = .0003), with the largest reductions in the parietal cortex (-37.6%; P < .0001) and

    The aim of this study was to investigate the effect of the timing of valve surgery on the clinical outcomes of patients with active infective endocarditis (IE) accompanied by cerebral complications. We retrospectively analysed a cohort of 568 patients, comprising 118 with non-haemorrhagic cerebral infarction (CI), 54 with intracranial haemorrhage (ICH) and 396 without cerebral events (C; control), who underwent surgery for left-sided active IE in 15 Japanese institutes from 2000 to 2011. The mean age was 58.4 ± 16.9 years in the CI group; 54.5 ± 17.4 years in the ICH group and 56.9 ± 16.0 years in the C group. Clinical outcomes were analysed according to the timing of surgery after the diagnosis of CI or ICH was made. In the CI group, there were 9 (7.6%) hospital deaths, 13 (11%) new cerebral events and 1 (0.8%) redo valve surgery. In the ICH group, there were 3 (5.6%) hospital deaths, 8 (14.8%) new cerebral events and 2 (3.7%) redo valve surgeries. In the C group, there were 36 (9.1%) hospital deaths, 23 (5.8%) new cerebral events and 9 (2.3%) redo valve surgeries. Risk factors for hospital death were prosthetic valve endocarditis (P = 0.045), high C-reactive protein (CRP; P < 0.001) and the elderly (P < 0.001) in the CI group. Delayed surgery (2 weeks after CI) seemed result in a higher incidence of hospital death in the CI group. Patients who had surgery between 15 and 28 days or after 29 days from the onset of CI had higher incidences of hospital death [odds ratio 5.90 (P = 0.107) and 4.92 (P = 0.137), respectively] compared with those who had surgery within 7 days. In the ICH group, risk factors for hospital death were high CRP (P = 0.002) and elderly (P < 0.001). Contrary to CI patients, patients who had surgery between 8 and 21 days or after 22 days after the onset of ICH had lower incidences of hospital death [odds ratio 0.79 (P = 0.843) and 0.12 (P = 0.200), respectively] compared with those who had surgery within 7 days.

    Whether posttraumatic stress disorder (PTSD) following radiation emergency has psychopathological, neurocognitive, and neurophysiological peculiarities is at issue. The goal was to explore the features and cerebral basis of "radiation" PTSD in the survivors of the Chernobyl accident. Subjects and Methods The cross-sectional study included 241 people, 219 of whom have been diagnosed with PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) criteria, among them 115 clean-up workers of the Chernobyl accident (34 with acute radiation sickness), 76 evacuees from the Chernobyl exclusion zone, 28 veterans of the war in Afghanistan, and 22 healthy unexposed individuals. Psychometric examinations, neurocognitive assessments, computerized electroencephalography, and cerebral vascular Doppler were used. "Radiation" PTSD includes "flashforward" phenomena and anticipating stress (projection of fear and danger to the future); somatoform disorders (depression, trait and state anxiety); and neurocognitive deficit (impaired memory and attention, auditory-verbal memory and learning, proactive and retroactive interference, cerebellar and stem symptoms, intellectual changes). The intima-media component, thickness of common carotid arteries, and common and left internal carotid arteries stenosis rates are increased in the liquidators. Changes of bioelectrical brain activity as a decrease of beta- and theta-power, together with an increase of alpha-power, were found in the Chernobyl accident survivors with PTSD. PTSD following radiation emergency is characterized by comorbidity of psychopathology, neurocognitive deficit, and cerebrovascular pathology with increased risk of cerebral atherosclerosis and stroke. The cerebral basis of this PTSD is proposed to be an abnormal communication between the pyramidal cells of the neocortex and the hippocampus, and deep brain structures. It is recommended that a system of emergency and long-term psychological

    Background: To compare the clinical characteristics, and short-term outcome of spinal cord infarction and cerebral infarction. Methods: Risk factors, concomitant diseases, neurological deficits on admission, and short-term outcome were registered among 28 patients with spinal cord infarction and 1075 patients with cerebral infarction admitted to the Department of Neurology, Haukeland University Hospital, Bergen, Norway. Multivariate analyses were performed with location of stroke (cord or brain), neurological deficits on admission, and short-term outcome (both Barthel Index [BI] 1 week after symptom onset and discharge home or to other institution) as dependent variables. Results: Multivariate analysis showed that patients with spinal cord infarction were younger, more often female, and less afflicted by hypertension and cardiac disease than patients with cerebral infarction. Functional score (BI) was lower among patients with spinal cord infarctions 1 week after onset of symptoms (P < 0.001). Odds ratio for being discharged home was 5.5 for patients with spinal cord infarction compared to cerebral infarction after adjusting for BI scored 1 week after onset (P = 0.019). Conclusion: Patients with spinal cord infarction have a risk factor profile that differs significantly from that of patients with cerebral infarction, although there are some parallels to cerebral infarction caused by atherosclerosis. Patients with spinal cord infarction were more likely to be discharged home when adjusting for early functional level on multivariate analysis. PMID:21915166

    Rathke's cleft cyst (RCC) apoplexy is a rare clinical entity. We report a case of apoplexy of an RCC followed by cerebral infarction. A 67-year-old woman was found lying on the street unconscious. She had fallen from her motorbike. On referral to our hospital she gradually regained consciousness and presented with no neurological deficits. CT showed a round and slightly hyperdense area in the suprasellar region. However, the attending physician did not find this abnormal finding on CT and the patient was discharged the same day. Thirteen days after the first emergency visit she developed left hemiparesis and dysarthria. CT showed a round hypodense area in the suprasellar region. The change of the density in the suprasellar region on CT suggested the pituitary apoplexy. CT also showed a low density area in the territory of the right middle cerebral artery, which indicated the cerebral infarction. MR angiography revealed poor visibility and stenotic changes of right middle cerebral arteries. Transsphenoidal surgery was performed. Histopathological findings confirmed a hemorrhagic RCC. Postoperative MR angiography showed that the visibility and stenosis of right middle cerebral arteries were recovered. This is the rare case of apoplexy of an RCC followed by cerebral infarction.

  3. The pitfalls of bedside regional cerebral oxygen saturation in the early stage of post cardiac arrest.

    It remains uncertain whether neuromonitoring reliably predicts outcome in adult post-cardiac arrest patients in the early stage treated with therapeutic hypothermia. Recent reports demonstrated a regional cerebral oxygen saturation of cardiac arrest patients on hospital arrival could predict their neurological outcome. There has been little discussion about the significance of regional cerebral oxygen saturation in patients with post-cardiac arrest syndrome. Amplitude-integrated electroencephalography monitoring may also provide early prognostic information for post-cardiac arrest syndrome. However, even when the initial electroencephalography is flat after the return of spontaneous circulation, good neurological outcome may still be obtainable if the electroencephalography shifts to a continuous pattern. The electroencephalography varied from flat to various patterns, such as flat, epileptic, or continuous during the first 24 h, while regional cerebral oxygen saturation levels varied even when the electroencephalography was flat. It is therefore difficult to estimate whether regional cerebral oxygen saturation accurately indicates the coupling of cerebral blood flow and metabolism in the early stage after cardiac arrest. Careful assessment of prognosis is necessary when relying solely on regional cerebral oxygen saturation as a single monitoring modality.

    A case of successful treatment by local fibrinolysis of a middle cerebral artery embolism caused by a thrombus from a left atrial myxoma is reported. A 62-year-old woman using a pacemaker and suffering from sick sinus syndrome was admitted on December 29th 1996, complaining of transient restlessness. CT and cerebral angiography revealed no abnormal vascular lesions. Eighteen months after the initial episode, she suffered a sudden onset of left hemiparesis and loss of consciousness. CT scan performed during the second episode revealed no lesions and, in particular, no early CT infarction sign, but emergent cerebral angiography revealed a right middle cerebral artery embolic occlusion. Local fibrinolysis using a tissue plasminogen activator was performed within 3 hours after the beginning of the episode, and partial recanalization was obtained within one hour after initiation of the fibrinolytic therapy. On the first hospital day, though CT revealed a small low-density area in the right basal ganglia, motor deficits gradually improved. Considering the possibility of a cardiac source of the embolism, trans-esophageal echocardiography was performed and revealed a left atrial tumor suspected to be a myxoma. It was removed by surgery on the 34th hospital day. Histological examination proved it to be a myxoma. Nine months after local fibrinolytic therapy, the patient returned to work. The diagnosis of cerebral embolism caused by cardiac myxoma is difficult to make at the time when the patient is first examined after admission. It is also hard to discover during emergent cerebral angiography with fibrinolytic therapy. Therefore, in the case of patients with cerebral embolism for which local fibrinolysis is ineffective, it should be presumed that cardiac myxoma is the source of the embolus. Direct PTA alone may be effective for such tumoral embolism.

    Hydatid disease is an accidental parasitosis, with brain location being rare. The case is reported of a 33year-old male, with no history of note, who was admitted to hospital with intracranial hypertension syndrome and right hemiparesis. Computed tomography showed a cystic lesion in the left frontal-parietal lobule. Surgery was performed by complete excision of the lesion, with a good outcome. Hydatid disease is a rare condition in the brain. Clinical suspicion is important for an early diagnosis. A review is presented on the pathogenesis, diagnosis and treatment of cerebral hydatid disease.

    While the caffeine induced cerebral vasoconstriction is well documented, the effects of oral ingestion of the drug in a dose range comparable to the quantities in which it is usually consumed and the intensity and duration of the associated reduction in cerebral circulation are unknown. Cerebral blood flow was measured via the TTXenon inhalation technique before and thirty and ninety minutes after the oral administration of 250 mg of caffeine or a placebo, under double-blind conditions. Caffeine ingestion was found to be associated with significant reductions in cerebral perfusion thirty and ninety minutes later. The placebo group showed no differences between the three sets of cerebral blood flow values.

    American youth are awash in media. They have television sets in their bedrooms, personal computers in their family rooms, and digital music players and cell phones in their backpacks. They spend more time with media than any single activity other than sleeping, with the average American eight- to eighteen-year-old reporting more than six hours of daily media use. The growing phenomenon of "media multitasking"--using several media concurrently--multiplies that figure to eight and a half hours of media exposure daily. Donald Roberts and Ulla Foehr examine how both media use and media exposure vary with demographic factors such as age, race and ethnicity, and household socioeconomic status, and with psychosocial variables such as academic performance and personal adjustment. They note that media exposure begins early, increases until children begin school, drops off briefly, then climbs again to peak at almost eight hours daily among eleven- and twelve-year-olds. Television and video exposure is particularly high among African American youth. Media exposure is negatively related to indicators of socioeconomic status, but that relationship may be diminishing. Media exposure is positively related to risk-taking behaviors and is negatively related to personal adjustment and school performance. Roberts and Foehr also review evidence pointing to the existence of a digital divide--variations in access to personal computers and allied technologies by socioeconomic status and by race and ethnicity. The authors also examine how the recent emergence of digital media such as personal computers, video game consoles, and portable music players, as well as the media multitasking phenomenon they facilitate, has increased young people's exposure to media messages while leaving media use time largely unchanged. Newer media, they point out, are not displacing older media but are being used in concert with them. The authors note which young people are more or less likely to use several

    Cerebral oedema can be classified as the tangible swelling produced by expansion of the interstitial fluid volume. Hydrocephalus can be succinctly described as the abnormal accumulation of cerebrospinal fluid (CSF) within the brain which ultimately leads to oedema within specific sites of parenchymal tissue. Using hydrocephalus as a test bed, one is able to account for the necessary mechanisms involved in the interaction between oedema formation and cerebral fluid production, transport and drainage. The current state of knowledge about integrative cerebral dynamics and transport phenomena indicates that poroelastic theory may provide a suitable framework to better understand various diseases. In this work, Multiple-Network Poroelastic Theory (MPET) is used to develop a novel spatio-temporal model of fluid regulation and tissue displacement within the various scales of the cerebral environment. The model is applied through two formats, a one-dimensional finite difference - Computational Fluid Dynamics (CFD) coupling framework, as well as a two-dimensional Finite Element Method (FEM) formulation. These are used to investigate the role of endoscopic fourth ventriculostomy in alleviating oedema formation due to fourth ventricle outlet obstruction (1D coupled model) in addition to observing the capability of the FEM template in capturing important characteristics allied to oedema formation, like for instance in the periventricular region (2D model).

    Cerebral ischemia is among the leading causes of death worldwide. It is characterized by a lack of blood flow to the brain that results in cell death and damage, ultimately causing motor, sensory, and cognitive impairments. Today, clinical treatment of cerebral ischemia, mostly stroke and cardiac arrest, is limited and new neuroprotective therapies are desperately needed. The Sirtuin family of oxidized nicotinamide adenine dinucleotide (NAD+)-dependent deacylases has been shown to govern several processes within the central nervous system as well as to possess neuroprotective properties in a variety of pathological conditions such as Alzheimer’s Disease, Parkinson’s Disease, and Huntington’s Disease, among others. Recently, Sirt1 in particular has been identified as a mediator of cerebral ischemia, with potential as a possible therapeutic target. To gather studies relevant to this topic, we used PubMed and previous reviews to locate, select, and resynthesize the lines of evidence presented here. In this review, we will first describe some functions of Sirt1 in the brain, mainly neurodevelopment, learning and memory, and metabolic regulation. Second, we will discuss the experimental evidence that has implicated Sirt1 as a key protein in the regulation of cerebral ischemia as well as a potential target for the induction of ischemic tolerance.

    Objective Harm avoidance, a trait indicative of behavioral inhibition, is associated with disability and dementia in old age, but the basis of these associations is uncertain. We test the hypothesis that higher level of harm avoidance is associated with increased likelihood of cerebral infarction. Methods Older persons without dementia completed a standard measure of harm avoidance. During a mean of 3.5 years of follow-up, 257 (of 1,082) individuals died of whom 206 (80%) underwent brain autopsy. Number of chronic cerebral infarcts (microscopic plus gross; expressed as 0,1, or >1) was assessed on neuropathologic examination, completed in 192 individuals at the time of analyses. Results On postmortem examination, chronic cerebral infarcts were found in 89 (42 with 1, 47 with >1). Higher harm avoidance was associated with higher likelihood of infarcts (odds ratio = 1.083, 95% confidence interval 1.040–1.128). A moderately high level of the trait (score=17, 75th percentile) was associated with a 2.4-fold increase in the likelihood of infarction compared to a moderately low level of the trait (score = 6, 25th percentile). These associations persisted in models that controlled for other cardiovascular risk factors. Conclusion Higher level of the harm avoidance trait may be a risk factor for cerebral infarction.

    To discuss the correlation of tongue manifestation with the site of cerebral infarction in patients with acute cerebral infarction. From March 2008 to February 2009, 200 cases of hospitalized patients with first unilateral cerebral infarction were chosen in the Department of Neurology, Xuanwu Hospital. The correlation of different tongue color, fur texture, fur color with the site of cerebral infarction was analyzed. The site of cerebral infarction in patients were compared between different tongue color by Chisquare test (P=0.314), and further correspondence analysis demonstrated that there was correlation between red tongue and cortical-subcortical infarction group. The site of cerebral infarction in patients were compared between thick fur group and thin fur group, cortical-subcortical infarction occurred more frequently in the former (P=0.0008). The site of cerebral infarction in patients were compared between dry fur group, moist fur group and smooth fur group, correspondence analysis demonstrated there was correlation between dry fur and cortical-subcortical group. The site of cerebral infarction in the patients were compared between white fur group, white-yellow fur group and yellow fur group (P=0.010), and correspondence analysis demonstrated there was correlation between white fur and brainstem infarction; white-yellow fur has relationship with cortical infarction; subcortical infarction was weakly related with white-yellow fur; there was closer relationship between yellow fur and cortical-subcortical infarction. The change of tongue manifestation was associated with the site of cerebral infarction in patients, providing a new combining site for diagnosing cerebrovascular diseases by integrative medicine.

    The neurovascular unit is an emerging concept that emphasizes homeostatic interactions between endothelium and cerebral parenchyma. Here, we show that cerebral endothelium are not just inert tubes for delivering blood, but they also secrete trophic factors that can be directly neuroprotective. Conditioned media from cerebral endothelial cells broadly protects neurons against oxygen-glucose deprivation, oxidative damage, endoplasmic reticulum stress, hypoxia, and amyloid neurotoxicity. This phenomenon is largely mediated by endothelial-produced brain-derived neurotrophic factor (BDNF) because filtering endothelial-conditioned media with TrkB-Fc eliminates the neuroprotective effect. Endothelial production of BDNF is sustained by beta-1 integrin and integrin-linked kinase (ILK) signaling. Noncytotoxic levels of oxidative stress disrupts ILK signaling and reduces endothelial levels of neuroprotective BDNF. These data suggest that cerebral endothelium provides a critical source of homeostatic support for neurons. Targeting these signals of matrix and trophic coupling between endothelium and neurons may provide new therapeutic opportunities for stroke and other CNS disorders.

    Preventative treatments for unruptured cerebral aneurysms include craniotomy, endovascular treatment, and follow up. Since there is no agreement as to the best procedure, it is important to provide adequate information so that the patient and physician can share in the decision-making process. A multi-media DVD was created to inform patients of the facts. This study examined how effectively this DVD changes patients' recognition including knowledge of unruptured cerebral aneurysms. Forty-seven patients with unruptured cerebral aneurysms who sought neurosurgery consultation between December 2005 and February 2006 completed a questionnaire before and after watching the DVD, as well as at 3 months follow up. Before watching the DVD, the average knowledge score was 8.72 out of 15 total points. The average score increased to 12.4 after watching the DVD (p < 0.001). At 3 months follow up, the average score was 10.34, which was still higher than before watching the DVD (p < 0.01). Participants' knowledge about treatment methods also increased after watching the DVD (p < 0.001). Compared to 63.2% who were satisfied with their treatment decision before watching the DVD, 69.6% were satisfied with their decision after watching the DVD. All participants responded that the use of multi-media images was helpful in better understanding treatment options and in making informed decisions. The DVD was favorably accepted as a decision support tool by patients with unruptured cerebral aneurysm and effectively increased patients' knowledge.

    Intrigue progression of hypertensive encephalopathy (HE) in older patients is that the development of cognitive impairment and high blood pressure underestimated, aslo exist without clinical manifestations. In recent decades convincing proved that the basis for the development of various diseases is cerebral dysfunction systems regulating brain blood flow, including--autoregulation system, which largely affects the blood supply to the brain. This explains the fact that patients with chronic brain ischemia cerebral hemodynamic status largely depends on the condition and stability of the regulatory mechanisms of systemic and cerebral hemodynamics, particularly of systemic blood pressure, regional cerebral blood supply, normalization which, in the early stages of development disorders, prevents of serious complications. In this paper the theoretical generalization and new solution of scientific and practical problems of hypertension influence on the formation of chronic cerebral ischemia in elderly patients on a background of hypertension--specified risk factors and especially the formation of a comprehensive study on the basis of clinical and neurological data, tool sand methods for neuroimaging research developed and improved methods of diagnosis. Found that in elderly patients with HE and HBP observed significant (P < 0.05) increase in the thickness of the intima-media complex was significantly higher (dextra--1.12 ± 0.03 and sinistra--1.11 ± 0.03), than middle-aged patients with hypertension at HE, which constitutes a violation of the elastic properties of the vascular wall. Established correlation data radionuclide study ultrasonic duplex scanning of vessels of the head and neck.

  13. Regulation of cerebral autoregulation by carbon dioxide.

    PubMed

    2015-01-01

    Cerebral autoregulation describes a mechanism that maintains cerebral blood flow stable despite fluctuating perfusion pressure. Multiple nonperfusion pressure processes also regulate cerebral perfusion. These mechanisms are integrated. The effect of the interplay between carbon dioxide and perfusion pressure on cerebral circulation has not been specifically reviewed. On the basis of the published data and speculation on the aspects that are without supportive data, the authors offer a conceptualization delineating the regulation of cerebral autoregulation by carbon dioxide. The authors conclude that hypercapnia causes the plateau to progressively ascend, a rightward shift of the lower limit, and a leftward shift of the upper limit. Conversely, hypocapnia results in the plateau shifting to lower cerebral blood flows, unremarkable change of the lower limit, and unclear change of the upper limit. It is emphasized that a sound understanding of both the limitations and the dynamic and integrated nature of cerebral autoregulation fosters a safer clinical practice.

    Cerebral palsy is a group of syndromes caused by non-progressive brain injury in the fetus or infant and can cause disabilities in childhood. Etiology of cerebral palsy has always been a hot topic for clinical scientists. More and more studies have shown that genetic factors are closely associated with the development of cerebral palsy. With the development and application of various molecular and biological techniques such as chromosome microarray analysis, genome-wide association study, and whole exome sequencing, new achievements have been made in the genetic research of cerebral palsy. Chromosome abnormalities, copy number variations, susceptibility genes, and single gene mutation associated with the development of cerebral palsy have been identified, which provides new opportunities for the research on the pathogenesis of cerebral palsy. This article reviews the advances in the genetic research on cerebral palsy in recent years.

    To test whether hospital advertising expenditures predict HCAHPS global ratings. We examined media advertising expenditures by 2,142 acute care hospitals in 209 markets in the United States. Data on hospital characteristics, location, and revenue came from CMS reports; system ownership was obtained from the American Hospital Association. Advertising data came from Kantar Media. HCAHPS data were obtained from HospitalCompare. Regression models examined whether hospitals' advertising spending predicts HCAHPS global measures and whether market concentration moderated this association. Hospital advertising spending was calculated by adding each individual hospital's expenditures to the amount spent by its parent health system, proportionally allocated by hospital revenue. Health system market share was used to estimate market concentration. These data were compared to hospitals' HCAHPS measures. In competitive markets (HHI below 1,000), hospital advertising predicted HCAHPS global measures. A 1-percent increase in advertising was associated with a 1.173-percent increase in patients rating the hospital a "9" or "10" on the HCAHPS survey and a 1.540-percent increase in patients who "definitely" would recommend the hospital. In concentrated markets, this association was not significant. In competitive markets, hospitals that spend more on advertising earn higher HCAHPS ratings on global measures. © Health Research and Educational Trust.

    Cardiac tumor is a rare, but clinically important source of cerebral embolism. We report a case of metastatic chondrosarcoma in the left atrium with multiple cerebral emboli. A computed tomography scan of the chest revealed a large mass in the left atrium and pulmonary vein. The patient underwent heart surgery to remove the metastatic chondrosarcoma in the left atrium, to prevent the formation of further systemic emboli and possible sudden death. The cardiac tumor resection was successful, and the patient was discharged from the hospital without any handicap. This is a rare case of metastatic cardiac tumor that was a source of emboli into the brain and was eradicated.

    Background Children with sickle cell disease (SCD) and moyamoya may benefit from indirect cerebral revascularization surgery in addition to chronic blood transfusion therapy for infarct prevention. We sought to compare overt and silent infarct recurrence rates in children with SCD undergoing revascularization. Methods This was a retrospective cohort study of all children with SCD and moyamoya treated at two children’s hospitals. Clinical events and imaging studies were reviewed. Results Twenty-seven children with SCD and confirmed moyamoya receiving chronic transfusion therapy were identified, of whom 12 underwent indirect cerebral revascularization. Two subjects had post-operative transient ischemic attacks and another had a subarachnoid blood collection, none of which caused permanent consequences. Two subjects had surgical wound infections. Among these 12 children, the rate of overt and silent infarct recurrence decreased from 13.4 infarcts/100 patient-years before revascularization to 0 infarcts/100 patient-years after revascularization (p=0.0057); the post-revascularization infarct recurrence rate was also significantly lower than the overall infarct recurrence of 8.87 infarcts/100 patient-years in 15 children without cerebral revascularization (p=0.025). Conclusion The rate of overt and silent infarct recurrence was significantly lower following indirect cerebral revascularization. A prospective study of cerebral revascularization in children with SCD is needed. PMID:27106860

    We describe a case of Duchenne muscular dystrophy (DMD) with multiple strokes related to dilated cardiomyopathy. A 13 year old boy, with advanced stage DMD was admitted to the hospital because of acute motor and sensory impairment in his right bodyside. Imaging study revealed lesions in basal ganglia and prerolandic cortex in the left hemisphere that were compatible with infarcts in the territory of the medial cerebral artery. Cardiologic evaluation revealed dilation of the left ventriculi and systolic dysfunction with ejection fraction of 35 40%. The symptoms evolved to a residual right hemiparesia. Five months later, the patient developed a transient episode of aphasia and the study performed in this case revealed lesions compatible with infarcts in basal ganglia and insular cortex of the right cerebral hemisphere. Cerebral infarction related to cardiomyopathy can worsen the clinical condition of patients with DMD. Early treatment of dilated cardiomyopathy with systolic dysfunction, including use of antithrombotic agents to prevent cerebrovascular complications, could help to improve the course of the disease.

The research was performed out of 33 children with Cerebral Palsy (aged 1-18 years) who attend Zespół Szkół Specjalnych number 103, Accident-Orthopaedic Department in Hospital nr 4 in Poznan and Rehabilitation Center "Bartek" in Poznań. The questionnaire was used in order to check whether there is any failure curvature in cervical, thoracic and lumbar spine in plantar and frontal plane. The study was performed by visual analysis of the spine in November and December in 2007. (1) The visual analysis of the vertebral column showed that the cervical spine is asymmetric among two children with hemiplegia bilateralis, three with hemiplegia spastica and one with atetosis. (2) Among group of patients with lumbar hyperlordosis there are eight who are diagnosed with hemiplegia bilateralis. (3) These are seven patients who have the proper position of pelvis in frontal plane and can stand by oneself (referring to Levene's Test for Equality of Variances p = 0.039820). (1) The failure posture is common among children with cerebral palsy. (2) Vertebral column is asymmetrical in frontal plane among many patients with cerebralpalsy, especially with hemiplegia spastica. (3) The position of pelvis in frontal plane influence on the ability of standing by oneself.

The aim of the study was to analyze neuroimaging findings in children with unilateral spastic cerebral palsy. The study was hospital based, which has included 106 patients with US CP (boys 72/girls 34, term 82/preterm 24). Neuroimaging findings were classified into 5 groups: Brain maldevelopment, predominant white matter injury, predominant gray matter injury, non specific findings and normal neuroimaging findings. Predominant white matter lesions where the most frequent (48/106,45.28%; term 35/preterm 13), without statistically significant difference between term and preterm born children (x2=0.4357; p=0.490517). Predominant gray matter lesions had 32/106 children, 30.19%; (term 25/preterm 7, without statistically significant difference between term and preterm born children (x2=0.902; p=0.9862). Brain malformations had 10/106 children, 9.43%, and all of them were term born. Other finding had 2/106 children, 1.89%, both of them were term born. Normal neuroimaging findings were present in14/106 patients (13.21%). Neuroimaging may help to understand morphological background of motor impairment in children with US CP. Periventricular white matter lesions were the most frequent, then gray matter lesions.

    Otitis media with effusion (OME) is the most common cause of paediatric hearing loss. No single treatment has proved its effectiveness. There is a lack of evidence-based medicine studies in the area of homeopathy. A prospective randomized, double blinded interventional placebo control study was conducted. Patients, from 2 months to 12 years, with OME diagnosed by pneumatic otoscopy (PNO) and tympanometry, were randomized into two groups. Both groups received aerosol therapy (mucolytics and corticosteroids). In addition, the experimental group (EG) received homeopathy (Agraphis nutans 5CH, Thuya Occidentalis 5CH, Kalium muriaticum 9CH and Arsenicum iodatum), and the placebo group (PG) placebo, both of them for 3 months. Patients were evaluated by PNO examination and tympanometry at baseline, at 45 and 90 days. 97 patients were enrolled. In the EG, 61.9% of individuals were cured (PNO went from negative in the 1st visit to positive in the 3rd visit) compared with 56.8% of patients treated with placebo. 4.8% of patients in the EG suffered a recurrence (positive PNO in the 2nd visit changed to negative in the 3rd visit) while 11.4% did in the PG. No significant difference was found. Adverse events were distributed similarly, except in the case of upper respiratory tract infections, which were less frequent in EG (3 vs. 13, p: 0.009). The homeopathic scheme used as adjuvant treatment cannot be claimed to be an effective treatment in children with OME. EUDRACT number: 2011-006086-17, PROTOCOL code: 55005646.

    1998-01-01

    Most writers assessing AIDS have been critical of the media's coverage of this epidemic. To ascertain the views of key elites on media coverage of AIDS, the authors surveyed chief state public health officers, chairs of legislative health committees, and directors of hospital associations. In general, these groups tended to reject criticisms that media handling of AIDS is unbalanced. Conversely, however, they also generally rate the media as not doing a good job of educating the public about AIDS. The media's success in accurately communicating professional perspectives regarding AIDS might have accounted for their relative lack of independent influence in AIDS policymaking. The media exhibited a "guard dog" role-protecting the health professionals' positions-instead of an agenda-setting role-dictating to the decision-makers what issues they should be addressing.

    It is becoming evident that type 2 diabetes mellitus is affecting brain energy metabolism. The importance of alternative substrates for the brain in type 2 diabetes mellitus is poorly understood. The aim of this study was to investigate whether ketone bodies are relevant candidates to compensate for cerebral glucose hypometabolism and unravel the functionality of cerebral mitochondria in type 2 diabetes mellitus. Acutely isolated cerebral cortical and hippocampal slices of db/db mice were incubated in media containing [U-(13)C]glucose, [1,2-(13)C]acetate or [U-(13)C]β-hydroxybutyrate and tissue extracts were analysed by mass spectrometry. Oxygen consumption and ATP synthesis of brain mitochondria of db/db mice were assessed by Seahorse XFe96 and luciferin-luciferase assay, respectively. Glucose hypometabolism was observed for both cerebral cortical and hippocampal slices of db/db mice. Significant increased metabolism of [1,2-(13)C]acetate and [U-(13)C]β-hydroxybutyrate was observed for hippocampal slices of db/db mice. Furthermore, brain mitochondria of db/db mice exhibited elevated oxygen consumption and ATP synthesis rate. This study provides evidence of several changes in brain energy metabolism in type 2 diabetes mellitus. The increased hippocampal ketone body utilization and improved mitochondrial function in db/db mice, may act as adaptive mechanisms in order to maintain cerebral energetics during hampered glucose metabolism.

    The transplantation of artificial blood vessels with < 6 mm inner diameter as substitutes for human arterioles or veins has not achieved satisfactory results. Umbilical vein has been substituted for ar-tery in vascular transplantation, but it remains unclear whether the stress relaxation and creep tween these vessels are consistent. In this study, we used the fetal umbilical vein and middle cere-bral artery from adult male cadavers to make specimens 15 mm in length, 0.196–0.268 mm in nica media thickness, and 2.82–2.96 mm in outer diameter. The results demonstrated that the stress decrease at 7 200 seconds was similar between the middle cerebral artery and fetal umbilical vein specimens, regardless of initial stress of 18.7 kPa or 22.5 kPa. However, the strain increase at 7 200 seconds of fetal umbilical veins was larger than that of middle cerebral arteries. Moreover, the stress relaxation experiment showed that the stress decrease at 7 200 seconds of the fetal umbilical vein and middle cerebral artery specimens under 22.5 kPa initial stress was less than the decrease in these specimens under 18.7 kPa initial stress. These results indicate that the fetal umbilical vein has appropriate stress relaxation and creep properties for transplantation. These properties are advantageous for vascular reconstruction, indicating that the fetal umbilical vein can be transplanted to repair middle cerebral artery injury. PMID:25206626

    Selective antegrade cerebral perfusion (SACP) for aortic arch surgery has evolved considerably since it was first reported. Various pressure rates have been investigated through animal models, as has the effect of warmer perfusate temperatures and hematocrit. Clinical research into pH management, the role of unilateral and bilateral perfusion, and core temperatures have further refined the procedure. We recommend the following protocol for SACP: perfusion pressure between 40-60 mmHg, flow rates between 6-10 mL/kg/min, and perfusate temperature of 20-28 °C; core cooling to 18-30 °C contingent on duration of arrest; alpha-stat pH management; hematocrit between 25-30%; near infrared spectroscopy to monitor cerebral perfusion; and bilateral perfusion when prolonged durations of SACP is anticipated.

    The purpose of this study was to examine if local thermo-applications affect central nervous reactions. In a crossover study, six normal, healthy volunteers at first received cold packs (Cryogel, 8-12 degrees C; Pino GmbH, Hamburg, Germany) and afterwards hot packs (Parafango, 50-60 degrees C; Pino GmbH), and another six volunteers started with the hot packs and had the cold packs later; both groups administered the hot and cold packs to their thighs. Before, during, and after treatment, cerebral blood flow velocity (CBFV) in the middle cerebri-artery (MCA) was measured continuously by transcranial Doppler sonography, whereas cerebral respiratory chain enzyme cytochrome aa3 (cCytaa3) and cerebral oxygen saturation (cHbO2) were measured by transcranial near infrared spectroscopy in frontal brain tissue. Furthermore, CO2 end-tidal and arterial blood pressure (noninvasive) were also measured. Six other volunteers received only one treatment; therefore, 15 measurements with cold and 15 measurements with hot packs were performed. During application of cold packs, a decrease of cHbO2 of 10.5% (P < 0.001) and cCytaa3 of 6.7% (P < 0.001) was found, whereas the CBFV(MCA) increased significantly (3.9%; P < 0.001) between preliminary and post-stimulus periods. When cold packs were removed, a significant increase of the cHbO2 (16.9%; P < 0.001) and cCytaa3 (9.7%; P < 0.001) was measured. With these values, cHbO2 and cCytaa3 showed an overshooting counterreaction beyond the initial level. When applying the hot packs, a contrary course of the parameters was found. cCytaa3 showed a significant increase of 9.3% (P < 0.001) at the end of the stimulus phase and a decrease of 1.9% (P = 0.02) during the post-stimulus period. The correlating increase of cHbO2 was significant at 13.7% (P < 0.005). At the end of the post-stimulus phase, a significant decrease of cHbO2 at 1.9% (P = 0.004) was recorded. With Parafango applications, a significant decrease of CBFV(MCA) at 6.9% (P < 0

  3. Enhanced Cholinergic Activity Improves Cerebral Blood Flow during Orthostatic Stress

    Cerebral blood flow (CBF) and consequently orthostatic tolerance when upright depends on dilation of the cerebral vasculature in the face of reduced perfusion pressure associated with the hydrostatic gradient. However, it is still unclear if cholinergic activation plays a role in this dilation. To determine if enhancing central cholinergic activity with the centrally acting acetylcholinesterase inhibitor, physostigmine would increase CBF when upright compared to the peripherally acting acetylcholinesterase inhibitor, neostigmine, or saline. We performed a randomized double-blind dose-ranging study that took place over 3 days in a hospital-based research lab. Eight healthy controls (six women and two men, mean age, 26 years; range 21–33) were given infusions of physostigmine, neostigmine, or saline on three different days. Five-minute tilts were repeated at baseline (no infusion), Dose 1 (0.2 μg/kg/min physostigmine; 0.1 μg/kg/min neostigmine) and Dose 2 (0.6 μg/kg/min physostigmine or 0.3 μg/kg/min neostigmine), and placebo (0.9% NaCl). Cerebral blood velocity, beat-to-beat blood pressure, and end-tidal CO2 were continuously measured during tilts. Physostigmine (0.6 μg/kg/min) resulted in higher cerebral blood velocity during tilt (90.5 ± 1.5%) than the equivalent neostigmine (85.5 ± 2.6%) or saline (84.8 ± 1.7%) trials (P < 0.05). This increase occurred despite a greater postural hypocapnia, suggesting physostigmine had a direct vasodilatory effect on the cerebral vasculature. Cerebral hypoperfusion induced by repeated tilts was eliminated by infusion of physostigmine not neostigmine. In conclusion, this study provides the first evidence that enhancement of central, not peripheral, cholinergic activity attenuates the physiological decrease in CBF seen during upright tilt. These data support the need for further research to determine if enhancing central cholinergic activity may improve symptoms in patients with symptomatic

    A 34-year-old man presented with a case of subdural empyema and cerebral abscess that developed 12 years after initial neurosurgical intervention for a traffic accident in 1998. Under a diagnosis of acute subdural hematoma and cerebral contusion, several neurosurgical procedures were performed at another hospital, including hematoma removal by craniotomy, external decompression, duraplasty, and cranioplasty. The patient experienced an epileptic seizure, and was referred to our hospital in March 2010. Magnetic resonance imaging revealed a cerebral abscess extending to the subdural space just under the previous surgical field. Surgical intervention was refused and antimicrobial treatment was initiated, but proved ineffective. Surgical removal of artificial dura and cranium with subdural empyema, and resection of a cerebral abscess were performed on May 12, 2010. No organism was recovered from the surgical samples. Meropenem and vancomycin were selected as perioperative antimicrobial agents. No recurrence of infection has been observed. Postneurosurgical subdural empyema and cerebral abscess are recently emerging problems. Infections of neurosurgical sites containing implanted materials occur in 6% of cases, usually within several months of the surgery. Subdural empyema and cerebral abscess developing 12 years after neurosurgical interventions are extremely rare. The long-term clinical course suggests less pathogenic organisms as a cause of infection, and further investigations to develop appropriate antimicrobial selection and adequate duration of antimicrobial administration for these cases are needed.

    Cerebral malaria is among the major causes of malaria-associated mortality and effective adjunctive therapeutic strategies are currently lacking. Central pathophysiological processes involved in the development of cerebral malaria include an imbalance of pro- and anti-inflammatory responses to Plasmodium infection, endothelial cell activation, and loss of blood-brain barrier integrity. However, the sequence of events, which initiates these pathophysiological processes as well as the contribution of their complex interplay to the development of cerebral malaria remain incompletely understood. Several cytokines and chemokines have repeatedly been associated with cerebral malaria severity. Increased levels of these inflammatory mediators could account for the sequestration of leukocytes in the cerebral microvasculature present during cerebral malaria, thereby contributing to an amplification of local inflammation and promoting cerebral malaria pathogenesis. Herein, we highlight the current knowledge on the contribution of cytokines and chemokines to the pathogenesis of cerebral malaria with particular emphasis on their roles in endothelial activation and leukocyte recruitment, as well as their implication in the progression to blood-brain barrier permeability and neuroinflammation, in both human cerebral malaria and in the murine experimental cerebral malaria model. A better molecular understanding of these processes could provide the basis for evidence-based development of adjunct therapies and the definition of diagnostic markers of disease progression.

    We have performed high dose photoradiation therapy in patients with cerebral tumors. Twenty-seven patients had gliomas, two had metastatic cancer of the brain, one had malignant meningioma. Hematoporphyrin derivative was administered intravenously. All patients underwent a craniotomy with a radical or partial excision of the tumor. There was no evidence of increased cerebral edema and other toxicity from the therapy, and all patients were discharged from the hospital within 15 days after surgery. On the basis of animal experiments our institute started using photodynamic therapy (PDT) as an adjuvant measure to the operative therapy in 30 cases of cerebral tumors. Ten of these patients were excluded from this group because of the short postoperative following time. Here, the details of our experiences are presented as follows: 106 of C6 type glioma cell strain were implanted into the frontal lobe of a Chinese hamster. Fourteen days later intracranial gliomas developed, which were larger than 4 mm in diameter, HpD in a dosage of 4 mg/kg was injected into the tail vein of the animals. The fluorescence was seen 5 minutes later. The diagnostic laser used was He-Ca (Hc-type 15A, made at Shanghai Laser Institute) with a wavelength of 441.6 nm, power of 30 mw. The fluorescence reached its peak point 24 hours later, and the normal tissue can be identified by the lack of fluorescence. Then, the tumor tissue was further radiated with an Ar laser (made in Nanjing Electronic Factory, type 360), pumped dye-laser (made in Changchun Optic Machinery Institute, type 901) with a wavelength of 630 nm, and an energy density of more than 200 Joules/cm2, which might get the tumor cells destroyed selectively. The effect of photoradiation may reach as deep as 4 - 7 mm into the brain tissue without cerebral edema or necrosis.

    Cerebral small vessel disease (SVD) is an important cause of stroke and cognitive impairment among the elderly and is a more frequent cause of stroke in Asia than in the US or Europe. Although traditional risk factors such as hypertension or diabetes mellitus are important in the development of cerebral SVD, the exact pathogenesis is still uncertain. Both, twin and family history studies suggest heritability of sporadic cerebral SVD, while the candidate gene study and the genome-wide association study (GWAS) are mainly used in genetic research. Robust associations between the candidate genes and occurrence of various features of sporadic cerebral SVD, such as lacunar infarction, intracerebral hemorrhage, or white matter hyperintensities, have not yet been elucidated. GWAS, a relatively new technique, overcomes several shortcomings of previous genetic techniques, enabling the detection of several important genetic loci associated with cerebral SVD. In addition to the more common, sporadic cerebral SVD, several single-gene disorders causing cerebral SVD have been identified. The number of reported cases is increasing as the clinical features become clear and diagnostic examinations are more readily available. These include cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy, COL4A1-related cerebral SVD, autosomal dominant retinal vasculopathy with cerebral leukodystrophy, and Fabry disease. These rare single-gene disorders are expected to play a crucial role in our understanding of cerebral SVD pathogenesis by providing animal models for the identification of cellular, molecular, and biochemical changes underlying cerebral small vessel damage.

    Abstract Transient global amnesia is now considered a very rare complication of cerebral angiography. Various etiological mechanisms have been suggested to account for this complication, but no consensus has been reached yet. This case report documents one of the few reported cases of cerebral angiography-related transient global amnesia associated with magnetic resonance imaging (MRI) evidence of unilateral hippocampal ischemia, most probably as a consequence of a transient reduction in regional hippocampal blood flow. However, the possibility of a direct neurotoxic effect of the nonionic contrast media Iomeprol on the Cornu ammonis – field 1 neurons cannot be firmly ruled out. We describe the case of a 54-year-old woman admitted to our department for left upper limb weakness with acute onset 8 days before. The brain computed tomography (CT) scan performed at admission revealed subacute ischemic lesions in the right watershed superficial territories and a right thalamic lacunar infarct. Diagnostic digital subtraction cerebral angiography was performed 4 days after admission with the nonionic contrast media Iomeprol. A few minutes after completion of the procedure, the patient developed symptoms suggestive for transient global amnesia. The brain MRI performed 22 hours after the onset of symptoms demonstrated increased signal within the lateral part of the right hippocampus on the diffusion-weighted imaging (DWI) sequences, associated with a corresponding reduction in the apparent diffusion coefficient (ADC) and increased signal on the fluid-attenuated inversion recovery (FLAIR) sequences, consistent with acute hippocampal ischemia and several T2/FLAIR hyperintensities in the right watershed superficial territories and in the right thalamus, corresponding to the lesions already identified on the CT scan performed at admission. A follow-up MRI, performed 2 months later, demonstrated the disappearance of the increased signal within the right hippocampus on the DWI

    A hospital study was carried out to compare parenting stress among 87 Malaysian mothers of children with cerebral palsy and a control group (comprising 87 mothers of children without disability who attended the walk-in paediatric clinic), using the Parenting Stress Index (PSI) questionnaire. Multiple regression analysis was used to determine socio-demographic and medical factors associated with child-domain stress (CDS) and parent-domain stress (PDS). Mothers of children with cerebral palsy scored significantly higher than control subjects on all sub-scales of CDS and PDS (p < 0.01), except for the sub-scale of 'role restriction'. The presence of cerebral palsy (p < 0.001) and activities of daily living (ADL) scores (p < 0.001) were significantly associated with CDS. Factors predictive of PDS were ADL scores (p < 0.001), number of hospitalizations over the past year (p = 0.024), level of maternal education (p = 0.018) and Chinese mothers (p < 0.001). Although this study demonstrated that Malaysian mothers of children with cerebral palsy experienced higher levels of stress than controls, the impact of cerebral palsy per se on parenting stress was modified by other factors such as increased care-giving demands, low maternal education and ethnic background. Habilitation should be directed at easing the burden of daily care, minimizing hospital re-admissions and targeting appropriate psychosocial support at specific subgroups to change parental perception and expectations.

    Cerebral ischemia remains one of the most frequent causes of death and disability worldwide. Animal models are necessary to understand complex molecular mechanisms of brain damage as well as for the development of new therapies for stroke. This review considers a certain range of animal models of cerebral ischemia, including several types of focal and global ischemia. Since animal models vary in specificity for the human disease which they reproduce, the complexity of surgery, infarct size, reliability of reproduction for statistical analysis, and adequate models need to be chosen according to the aim of a study. The reproduction of a particular animal model needs to be evaluated using appropriate tools, including the behavioral assessment of injury and non-invasive and post-mortem control of brain damage. These problems also have been summarized in the review.

    In order to evaluate the clinical and prognostic significance of early hyperfibrinogenemia in patients with transient ischemic attack (TIA) and ischemic cerebral infarction (ICI), we analyzed the relationships between plasma fibrinogen, brain damage severity, clinical status on admission and intra-hospital mortality. Vascular damage severity was estimated by measuring the necrotic area by computed axial tomography (CT) and indirectly by means of changes in some plasma enzymes (CK, LDH, GPT/ALT, and GOT/AST). Plasma fibrinogen levels were statistically higher in ICI than in TIA and control subjects (p < 0.0005; analysis of variance). Moreover, plasma fibrinogen was directly related to the extension of the necrotic area at CT scan (p < 0.05) and in ICI patients was positively correlated with CK (r = 0.50, p < 0.01), LDH (r = 0.41, p < 0.05) and GOT/AST (r = 0.42, p < 0.05) serum levels, but not with GPT/ALT. A higher plasma fibrinogen value was observed in patients with stupor or coma compared with those with alert consciousness (p < 0.05). In patients who died during hospitalization, fibrinogen levels were higher than those of subjects who were discharged (p < 0.005). The results indicate that in the early phase of cerebral ischemia, plasma fibrinogen levels are related to the severity of the clinical status and to the extension of the brain vascular damage, thus representing a negative clinical and prognostic factor of the disease.

    Cerebral fractional oxygen extraction (FOE) was monitored in 30 children, using near infrared spectroscopy during cardiopulmonary bypass, to investigate the effect of hypothermia and circulatory arrest. One group of children (n = 15) underwent profound hypothermia with total circulatory arrest (n = 8) or continuous flow (n =7). Another group (n = 15), of whom only one had circulatory arrest, underwent mild (n = 6) or moderate (n = 9) hypothermia.
 The mean FOE (SD) before bypass was 0.35 (0.12) and this correlated negatively with the preoperative arterial oxygen content (r=−0.58). Between the stage of cooling on bypass and cold bypass there was a reduction in FOE in all groups. Between cold bypass and rewarming there was an increase in FOE only in the groups with continuous flow. In the circulatory arrest group, the FOE remained low during rewarming and was significantly lower than that of the continuous flow group. No patients died and none had neurological abnormalities postoperatively.
 Apparent changes in oxidised cytochrome oxidase concentration were also monitored using near infrared spectroscopy. There was a fall in cytochrome aa3 on starting cardiopulmonary bypass, but there were no significant differences in the changes in cytochrome aa3 between any stage in any of the patient groups.
 Using this non-invasive technique, cooling was shown to reduce cerebral FOE. During rewarming on bypass there was an increase in cerebral FOE only in patients who had had continuous flow bypass. In contrast, the cerebral FOE in those with circulatory arrest remained constant after arrest and during the duration of the study. This may have implications for the timing of hypoxic brain injury.

  15. Cerebral circulation during acceleration stress

    NASA Astrophysics Data System (ADS)

    Cirovic, Srdjan

    A mathematical model of the cerebrovascular system has been developed to examine the influence of acceleration on cerebral circulation. The objective is to distinguish the main factors that limit cerebral blood flow in pilots subjected to accelerations which exceed the gravitational acceleration of the earth (Gz > 1). The cerebrovascular system was approximated by an open-loop network of elastic tubes and the flow in blood vessels was modeled according to a one-dimensional theory of flow in collapsible tubes. Since linear analysis showed that the speed of pulse propagation in the intracranial vessels should not be modified by the skull constraint, the same governing equations were used for the intracranial vessels as for the rest of the network. The steady and pulsatile components of the cerebrospinal fluid pressure were determined from the condition that the cranial volume must be conserved. After the qualitative aspects of the model results were verified experimentally, the open-loop geometry was incorporated into a global mathematical model of the cardiovascular system. Both the mathematical models and the experiment show that cerebral blood flow diminishes for Gz > 1 due to an increase in the resistance of the large veins in the neck, which collapse as soon as the venous pressure becomes negative. In contrast, the conservation of the cranial volume requires that the cerebrospinal and venous pressure always be approximately the same, and the vessels contained in the cranial cavity do not collapse. Positive pressure breathing provides protection by elevating blood arterial and venous pressures at the heart, thus preventing the venous collapse and maintaining the normal cerebral vascular resistance.

    1. By means of a critical review we tried to establish whether there is evidence from controlled trials in humans on the efficacy of Ginkgo biloba extracts in cerebral insufficiency. 2. The methodological quality of 40 trials on Ginkgo and cerebral insufficiency was assessed using a list of predefined criteria of good methodology, and the outcome of the trials was interpreted in relation to their quality. A comparison of the quality was made with trials of co-dergocrine, which is registered for the same indication. 3. There were eight well performed trials out of a total of 40. Shortcomings were limited numbers of patients included, and incomplete description of randomization procedures, patient characteristics, effect measurement and data presentation. In no trial was double-blindness checked. Virtually all trials reported positive results, in most trials the dosage was 120 mg Ginkgo extract a day, given for at least 4-6 weeks. For the best trials, there were no marked differences in the quality of the evidence of the efficacy of Ginkgo in cerebral insufficiency compared with co-dergocrine. The results of the review may be complicated by a combination of publication bias and other biases, because there were no negative results reported in many trials of low methodological quality. 4. Positive results have been reported for Ginkgo biloba extracts in the treatment of cerebral insufficiency. The clinical evidence is similar to that of a registered product which is prescribed for the same indication. However, further studies should be conducted for a more detailed assessment of the efficacy. PMID:1457269

    IMPORTANCE Cerebral microbleeds (CMBs) are collections of blood breakdown products that are a common incidental finding in magnetic resonance imaging of elderly individuals. Cerebral microbleeds are associated with cognitive deficits, but the mechanism is unclear. Studies show that individuals with CMBs related to symptomatic cerebral amyloid angiopathy have abnormal vascular reactivity and cerebral blood flow (CBF), but, to our knowledge, abnormalities in cerebral blood flow have not been reported for healthy individuals with incidental CMBs. OBJECTIVE To evaluate the association of incidental CMBs with resting-state CBF, cerebral metabolism, cerebrovascular disease, β-amyloid (Aβ), and cognition. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional study of 55 cognitively normal individuals with a mean (SD) age of 86.8 (2.7) years was conducted from May 1, 2010, to May 1, 2013, in an academic medical center in Pittsburgh; data analysis was performed between June 10, 2013, and April 9, 2015. INTERVENTIONS 3-Tesla magnetic resonance imaging was performed with susceptibility-weighted imaging or gradient-recalled echo to assess CMBs, arterial spin labeling for CBF, and T1- and T2-weighted imaging for atrophy, white matter hyperintensities, and infarcts. Positron emission tomography was conducted with fluorodeoxyglucose to measure cerebral metabolism and Pittsburgh compound B for fibrillar Aβ. Neuropsychological evaluation, including the Clinical Dementia Rating scale, was performed. MAIN OUTCOMES AND MEASURES Magnetic resonance images were rated for the presence and location of CMBs. Lobar CMBs were subclassified as cortical or subcortical. Measurements of CBF, metabolism, and Aβ were compared with the presence and number of CMBs with voxelwise and region-of-interest analyses. RESULTS The presence of cortical CMBs was associated with significantly reduced CBF in multiple regions on voxelwise and region-of-interest analyses (percentage difference in global CBF,

    Changes in cerebral blood flow during incremental increases of intracranial pressure produced by infusion of fluid into the cisterna magna were studied in anaesthetized baboons. Cerebral blood flow remained constant at intracranial pressure levels up to approximately 50 mm Hg. At intracranial pressure levels between 50-96 mm Hg a marked increase in cerebral blood flow occurred, associated with the development of systemic hypertension and changes in cerebrovascular resistance. Further increases of intracranial pressure led to a progressive fall in cerebral blood flow. Prior section of the cervical cord prevented both the increase in cerebral blood flow and the systemic hypertension. Alteration of cerebral perfusion pressure by bleeding during the hyperaemia in a further group of animals suggested that autoregulation was at least partially preserved during this phase. After maximum hyperaemia had occurred, however, autoregulation appeared to be lost. The clinical implications of these findings are discussed. PMID:4624687

    Objective To compare the chronological age and bone age among cerebral palsy patients in the outpatient clinic and its correlation with the type of neurological involvement, gender and functional status. Methods 401 patients with spastic cerebral palsy, and ages ranging from three months to 20 years old, submitted to radiological examination for bone age and analyzed by two independent observers according Greulich & Pyle. Results In the topographic distribution, there was a significant delay (p<0.005) in tetraparetic (17.7 months), hemiparetic (10.1 months), and diparetic patients (7.9 months). In the hemiparetic group, the mean bone age in the affected side was 96.88 months and the uncompromised side was 101.13 months (p<0.005). Regarding functional status, the ambulatory group showed a delay of 18.73 months in bone age (p<0.005). Comparing bone age between genders, it was observed a greater delay in males (13.59 months) than in females (9.63 months), but not statistically significant (p = 0.54). Conclusion There is a delay in bone age compared to chronological age influenced by the topography of spasticity, functional level and gender in patients with cerebral palsy.

    Cerebral hytatid cysts (HC) are extremely rare, forming 2% of all intra cranial space occupying lesions even in counties where the disease is endemic. HC diagnosis is usually based on a pathognomonic computed tomography (CT) pattern. In order to assess the value of MR we reviewed the CT (n=25) and magnetic resonance (MR, n=4 including diffusion and proton magnetic resonance spectroscopy in 1) imaging of 25 patients with pathologically confirmed cerebral hydatid disease. 19 HC were seen in children under 16 years. All were supra tentorial with 22 in the middle cerebral artery territory. HC was solitary in 18 cases, unilocular in 23 and multi-vesicular in 2 with heavily calcified pericyst in 1. 2 cysts were intra ventricular and 1 intra aqueducal. The most typical features were well defined, smooth thin walled spherical or oval cystic lesions of CSF density and/or signal with considerable mass effect (20/25). Surrounding oedema with complete or incomplete rim enhancement was seen in 3 cases which were labelled as complicated and/or infected cysts. Although CT is diagnostic of hydatid disease in almost all cases (22/25), MRI including diffusion and spectroscopy precisely demonstrate location, number, cyst capsule, type of signal and enhancement and allows diagnosis of atypical or complicated HC and appears more helpful in surgical planning.

    After a brief clinical and pathophysiological approach, the papers presented in this book are devoted to CT and angiography. Concerning CT, a particular study has been made of cerebral arterial territories on cuts parallel to the orbito-meatal line: these are very important in making the differential diagnosis from some tumors. Also concerning CT, a paper has been devoted to cerebral ''lacunae.'' The term ''lacuna'' as far as CT imaging is concerned, should be reserved only for those hypodense areas corresponding to small cavities containing fluid, which are sequelae of infarcts in the territory of penetrating arteries. Before this sequellar state come all the evolutive states of a small deep infarct. The angiographic study specifies the indications of angiography in the study of cerebral ischemia, and the techniques to be used. It shows the main etiologic aspects. Because of the important place of vascular surgery today, it seemed necessary to show also the main post operative angiographic aspects. After CT and angiography, some pages are reserved to more modern techniques. Finally, some pages are devoted to certain particular associations and etiologies: childhood, cardiopathies, migraine, oral contraception and end with venous infarction.

    Takotsubo cardiomyopathy can induce cerebral embolic stroke because of intracardiac thrombosis, but the timing of cardiogenic embolism relating to takotsubo cardiomyopathy has not been well described. We evaluated a 71-year-old woman with takotsubo cardiomyopathy, who developed cardiogenic cerebral embolism after recovery of cardiac wall motion. Nevertheless, we treated her with anticoagulation therapy. The present clinical observation suggests that attention should be paid to the timing when takotsubo cardiomyopathy resolves against risk of cardiogenic cerebral embolism.

    Parental age and birth order were studied in 251 patients with cerebral palsy. No parental age or birth order effects were observed in spastic quadriplegia or diplegia, but a paternal age effect was detected in those with athetoid/dystonic cerebral palsy and congenital hemiplegia. These observations indicate that some cases of athetoid/dystonic or hemiplegic cerebral palsy might arise by fresh dominant genetic mutation. PMID:8423607

    Severe anemia, defined as a hemoglobin level of less than 5.0 g/dL, affects millions of children worldwide. The brain has a high basal demand for oxygen and is especially vulnerable to hypoxemia. Previous studies have documented neurocognitive impairment in children with severe anemia. Data on cerebral tissue oxygenation in children with severe anemia and their response to blood transfusion are limited. To measure hemoglobin saturation in cerebral tissue (cerebral tissue oxygen saturation [tSo2]) before, during, and after blood transfusion in a cohort of children presenting to hospital with severe anemia. This was a prospective, observational cohort study conducted from February 2013 through May 2015 and analyzed in July 2015 at a university hospital pediatric acute care facility in Kampala, Uganda, of 128 children, ages 6 to 60 months who were enrolled in a larger clinical trial, with a presenting hemoglobin level of less than 5.0 g/dL and a blood lactate level greater than 5mM. Most children had either malaria or sickle cell disease. Red blood cell (RBC) transfusion given as 10 mL/kg over 120 minutes. Clinical and laboratory characteristics of children with pretransfusion cerebral tSo2 levels less than 65%, 65% to 75%, and greater than 75%. Change in cerebral tSo2 as a result of transfusion. Of 128 children included in the study, oximetry results in 8 cases were excluded owing to motion artifacts; thus, 120 were included in this analysis. Cerebral tSo2 values prior to transfusion ranged from 34% to 87% (median, 72%; interquartile range [IQR], 65%-76%). Eighty-one children (67%) demonstrated an initial cerebral tSo2 level (≤75%) corresponding to an oxygen extraction ratio greater than 0.36. Patients with sickle cell disease (n = 17) and malaria (n = 15) contributed in nearly equal numbers to the subgroup with an initial cerebral tSo2 (<65%). The level of consciousness, hemoglobin concentration, blood lactate level, and thigh muscle tSo2 level were poor

    In this review, we focus our discussion on studies examining effects on children and young adults. We believe that the current epidemic of youth violence in the United States justifies a focus on this vulnerable segment of society. We consider media effects on individual children's behaviors, such as imitating aggressive acts. In addition, we examine how the media influence young people's perceptions of norms regarding interpersonal relationships. Next, we assess mass media effects on societal beliefs, or what children and adolescents think the "real world" is like. We suggest these media influences are cumulative and mutually reinforcing, and discuss the implications of repeated exposure to prominent and prevalent violent media messages. Finally, we catalog multiple intervention possibilities ranging from education to regulation. From a public health perspective, therefore, we evaluate the effects that pervasive media messages depicting violence have on young people and present multiple strategies to promote more healthful outcomes.

    Changes in cerebral blood flow with increasing intracranial pressure were studied in anaesthetized baboons during expansion of a subdural balloon in one of two different sites. With an infratentorial balloon, cerebral blood flow bore no clear relation to intracranial pressure, but was linearly related to cerebral perfusion pressure. Apart from an initial change in some animals, cerebrovascular resistance remained constant with increasing intracranial pressure, and autoregulation appeared to be lost from the outset. With a supratentorial balloon, cerebral blood flow remained constant as intracranial pressure was increased to levels around 60 mm Hg, corresponding to a cerebral perfusion pressure range of approximately 100 to 40 mmHg. Cerebrovascular resistance fell progressively, and autoregulation appeared to be effective during this phase. At higher intracranial pressure levels (lower cerebral perfusion pressure levels), autoregulation was lost and cerebral blood flow became directly dependent on cerebral perfusion pressure. The importance of the cause of the increase in intracranial pressure on the response of the cerebral circulation and the relevance of these findings to the clinical situation are discussed.

    The bilateral cervical sympathectomy in anesthetized cats with initial arterial pressure (AP) 80--115 mm Hg increased the total blood flow while decreasing the local cerebral blood flow. In initial AP 116--135 mm Hg no effect on the total cerebral blood flow occurred while the local cerebral blood flow diminished insignificantly. If the AP was 136--180 mm Hg, the sympathectomy effect was only revealed after preliminary activation of the sympathetic nervous system. The effect of the sympathectomy depends on initial cerebral vascular tone, the perfusion pressure being one of the major factors.

    Cerebral radionuclide angiography can demonstrate decreased or normal radioactivity in the affected region during the arterial phase in patients who have sustained a cerebral vascular accident and thus enhances the diagnostic specificity of the static brain image. In an occasional patient, however, a seemingly paradoxical pattern of regional hyperperfusion with a return to normal or subnormal perfusion following the acute phase has been observed. This phenomenon, called "luxury perfusion," has been defined using intra-arterial 133Xe for semiquantitative cerebral blood flow measurements and should be kept in mind as a potentially misleading cerebral imaging pattern.

    Objectives: To determine the dietary practices of Saudi cerebral palsy (CP) children. Methods: A self-administered questionnaire was used to collect the following information from parents of CP children: demographics, main source of dietary information, frequency of main meals, foods/drinks used for main meals and in-between-meals. Results: Parents of 157 CP children participated. Parents were divided into three, while children were divided into two age groups. The main sources of dietary information included popular media (46.5%) and dentist (36.3%). Most of the children had three meals (71.3%) or two meals (24.8%) daily. Choices for main meals included meats (68.8%), vegetables (65.6%), fruits (28.4%) and puddings (38.9%). The main three drinks choices with main meals included packed juices (59.9%), bottled water (58.8%) and fresh fruit juices (33.1%). The choices for in-between meals snacks included biscuits (61.1%), potato chips (51.6%), fruits (43.9%) and chocolates (41.4%). The choice of drinks with snacks was similar to that used with main meals. In cross-tabulation, older parents used meat (p=.03) and soft drinks (p=.04) more often for their children’s main meals. Older children were given meat (p=.004) and soft drinks (p=.04) more often with main meals. Older children were given potato chips as snacks more often than younger children (p=.02), and there was a trend towards use of chocolates as snacks in older children (p=.08). Conclusion: Parents of CP children need to be educated about dietary practices of their children especially in areas such as the use of packed juices, dairy products, soft drinks and chocolates.

    Pediatricians care for children's growth and development from the time they are born until they become adults. In addition, pediatricians must be vigilant for external influences. Technology influences children of all ages. Seventy-five percent of teenagers own cell phones, with 25% using them for social media. Technology can lead to an increase in skills and social benefits but there is also the potential for harm such as sexting, cyberbullying, privacy issues, and Internet addiction, all of which can affect health. Pediatricians must become well versed in the new media to provide media-oriented anticipatory guidance and advice on media-related issues. Copyright © 2012 Elsevier Inc. All rights reserved.

    Media use has been on the rise in adolescents overall, and in particular, the amount of media multitasking-multiple media consumed simultaneously, such as having a text message conversation while watching TV-has been increasing. In adults, heavy media multitasking has been linked with poorer performance on a number of laboratory measures of cognition, but no relationship has yet been established between media-multitasking behavior and real-world outcomes. Examining individual differences across a group of adolescents, we found that more frequent media multitasking in daily life was associated with poorer performance on statewide standardized achievement tests of math and English in the classroom, poorer performance on behavioral measures of executive function (working memory capacity) in the laboratory, and traits of greater impulsivity and lesser growth mindset. Greater media multitasking had a relatively circumscribed set of associations, and was not related to behavioral measures of cognitive processing speed, implicit learning, or manual dexterity, or to traits of grit and conscientiousness. Thus, individual differences in adolescent media multitasking were related to specific differences in executive function and in performance on real-world academic achievement measures: More media multitasking was associated with poorer executive function ability, worse academic achievement, and a reduced growth mindset.

    Children with cerebral palsy in low-resource settings are at high risk of malnutrition, which further increases their risk of poor health outcomes. However, there are few available data on specific risk factors for malnutrition among children with cerebral palsy in the developing world. We performed a case-control study among children with cerebral palsy receiving care at a tertiary care hospital in Gaborone, Botswana. Children with cerebral palsy and malnutrition were identified according to World Health Organization growth curves and compared with subjects with cerebral palsy without malnutrition. Risk factors for malnutrition were identified using multivariable logistic regression models. These risk factors were then used to generate a Malnutrition Risk Score, and Receiver Operating Characteristic curves were used to identify optimal cutoffs to identify subjects at high risk of malnutrition. We identified 61 children with cerebral palsy, 26 of whom (43%) met criteria for malnutrition. Nonambulatory status (odds ratio 13.8, 95% confidence interval [CI] 3.8-50.1, P < 0.001) and a composite measure of socioeconomic status (odds ratio 1.6, 95% CI 1.0-2.5, P = 0.03) were the strongest risk factors for malnutrition. A Malnutrition Risk Score was constructed based on these risk factors, and receiver operating characteristic curve analysis demonstrated excellent performance characteristics of this score (area under the curve 0.92, 95% CI 0.89-0.94). Malnutrition is common among children with cerebral palsy in Botswana, and a simple risk score may help identify children with the highest risk. Further studies are needed to validate this screening tool and to determine optimal nutritional interventions in this population. Copyright © 2017 Elsevier Inc. All rights reserved.

    Objectives: Aneurysmal subarachnoid hemorrhage often leads to death and poor clinical outcome. Injury occurring during the first 72 hours is termed “early brain injury,” with disruption of the nitric oxide pathway playing an important pathophysiologic role in its development. Quantitative electroencephalographic variables, such as α/δ frequency ratio, are surrogate markers of cerebral ischemia. This study assessed the quantitative electroencephalographic response to a cerebral nitric oxide donor (intravenous sodium nitrite) to explore whether this correlates with the eventual development of delayed cerebral ischemia. Design: Unblinded pilot study testing response to drug intervention. Setting: Neuroscience ICU, John Radcliffe Hospital, Oxford, United Kingdom. Patients: Fourteen World Federation of Neurosurgeons grades 3, 4, and 5 patients (mean age, 52.8 yr [range, 41–69 yr]; 11 women). Interventions: IV sodium nitrite (10 μg/kg/min) for 1 hour. Measurements and Main Results: Continuous electroencephalographic recording for 2 hours. The alpha/delta frequency ratio was measured before and during IV sodium nitrite infusion. Seven of 14 patients developed delayed cerebral ischemia. There was a +30% to +118% (range) increase in the alpha/delta frequency ratio in patients who did not develop delayed cerebral ischemia (p < 0.0001) but an overall decrease in the alpha/delta frequency ratio in those patients who did develop delayed cerebral ischemia (range, +11% to –31%) (p = 0.006, multivariate analysis accounting for major confounds). Conclusions: Administration of sodium nitrite after severe subarachnoid hemorrhage differentially influences quantitative electroencephalographic variables depending on the patient’s susceptibility to development of delayed cerebral ischemia. With further validation in a larger sample size, this response may be developed as a tool for risk stratification after aneurysmal subarachnoid hemorrhage. PMID:27441898

    OBJECTIVE: To identify neonatal risk factors for cerebral palsy among very preterm babies and in particular the associations independent of the coexistence of antenatal and intrapartum factors. DESIGN: Case-control study. SETTING: Oxford health region. SUBJECTS: Singleton babies born between 1984 and 1990 at less than 32 weeks' gestation who survived to discharge from hospital: 59 with cerebral palsy and 234 randomly selected controls without cerebral palsy. MAIN OUTCOME MEASURES: Adverse neonatal factors expressed as odds ratios and 95% confidence intervals. RESULTS: Factors associated with an increased risk of cerebral palsy after adjustment for gestational age and the presence of previously identified antenatal and intrapartum risk factors were patent ductus arteriosus (odds ratio 2.3; 95% confidence interval 1.2 to 4.5), hypotension (2.3; 1.3 to 4.7), blood transfusion (4.8; 2.5 to 9.3), prolonged ventilation (4.8; 2.5 to 9.0), pneumothorax (3.5; 1.6 to 7.6), sepsis (3.6; 1.8 to 7.4), hyponatraemia (7.9; 2.1 to 29.6) and total parenteral nutrition (5.5; 2.8 to 10.5). Seizures were associated with an increased risk of cerebral palsy (10.0; 4.1 to 24.7), as were parenchymal damage (32; 12.4 to 84.4) and appreciable ventricular dilatation (5.4; 3.0 to 9.8) detected by cerebral ultrasound. CONCLUSION: A reduction in the rate of cerebral palsy in very preterm babies requires an integrated approach to management throughout the antenatal, intrapartum, and neonatal periods. PMID:9040385

    Background Altered cerebrovascular tone is implicated in reversible cerebral vasoconstriction syndrome (RCVS). We evaluated vasomotor reactivity using bedside transcranial Doppler in RCVS patients. Methods In this retrospective case-control study, middle cerebral artery (MCA) blood flow velocities were compared at rest and in response to breath-hold in RCVS ( n = 8), Migraineurs ( n = 10), and non-headache Controls ( n = 10). Hyperventilation response was measured in RCVS. Results In RCVS, Breath Holding Index (BHI) was severely reduced in seven of eight patients and 14/16 MCAs; seven of 16 MCAs showed exhausted (BHI < 0.1) or inverted (BHI < 0) vasomotor reactivity. Mean BHI in RCVS (0.23 ± 0.5) was significantly lower than Migraine (1.52 ± 0.57) and Controls (1.51 ± 0.32), p < 0.001. Triphasic velocity responses were seen in all groups. The maximum Vmean decline during the middle negative phase was -15.5 ± 9.2% in RCVS, -15.4 ± 7% in Migraine, and -10.3 ± 5% in Controls ( p = 0.04). In the late positive phase, average Vmean increase was 6.2 ± 14% in RCVS, which was significantly lower ( p < 0.001) than Migraine (30.5 ± 11%) and Controls (30.2 ± 6%). With hyperventilation, RCVS patients showed 23% decrease in Vmean. Conclusion Cerebral arterial tone is abnormal in RCVS, with proximal vasoconstriction and abnormally reduced capacity for vasodilation. Further studies are needed to determine the utility of BHI to diagnose RCVS before angiographic reversibility is established, and to estimate prognosis.

    1998-01-01

    Total (T-Ca), albumin corrected (A-Ca) and ionized (Ca++) serum calcium levels were measured in patients affected by transient ischemic attack (TIA) and ischemic cerebral infarction (ICI), in order to evaluate the clinical and prognostic significance of calcemic status during the acute phase of these events. These results demonstrate that the calcium level is decreased in cerebral ischemia and that more substantial changes are observed in ICI than in TIA and controls (p < 0.0001, p < 0.02 and p < 0.0001 respectively for T-Ca, A-Ca and Ca++; analysis of variance). The mean T-Ca was significantly reduced in patients who died during hospitalization compared with values observed in survivors (p < 0.005), whereas A-Ca and Ca++ were not different. The calcium changes observed in the early phase of TIA and ICI suggest that the severity of cerebral ischemia may condition the amount of its acute decrease. The cause of hypocalcemia is unclear (primary effect or secondary epiphenomenon of cerebral ischemia?), but when A-Ca and Ca++ are considered, its in-hospital unfavorable prognostic role may be excluded.

    Large cerebral aneurysms present a danger of rupture or brain compression. In some cases, clinicians may attempt to change the pathological hemodynamics in order to inhibit disease progression. This can be achieved by changing the vascular geometry with an open surgery or by deploying a stent-like flow diverter device. Patient-specific CFD models can help evaluate treatment options by predicting flow regions that are likely to become occupied by thrombus (clot) following the procedure. In this study, alternative flow scenarios were modeled for several patients who underwent surgical treatment. Patient-specific geometries and flow boundary conditions were obtained from magnetic resonance angiography and velocimetry data. The Navier-Stokes equations were solved with a finite volume solver Fluent. A porous media approach was used to model flow-diverter devices. The advection-diffusion equation was solved in order to simulate contrast agent transport and the results were used to evaluate flow residence time changes. Thrombus layering was predicted in regions characterized by reduced velocities and shear stresses as well as increased flow residence time. The simulations indicated surgical options that could result in occlusion of vital arteries with thrombus. Numerical results were compared to experimental and clinical MRI data. The results demonstrate that image-based CFD models may help improve the outcome of surgeries in cerebral aneurysms. acknowledge R01HL115267.

    As the organ shortage continues to grow, the creation of social media communities by transplant hospitals and the public is rapidly expanding to increase the number of living donors. Social media communities are arranged in myriad ways and without standardization, raising concerns about transplant candidates' and potential donors' autonomy and quality of care. Social media communities magnify and modify extant ethical issues in deceased and living donation related to privacy, confidentiality, professionalism, and informed consent, and increase the potential for undue influence and coercion for potential donors and transplant candidates. Currently, no national ethical guidelines have been developed in the United States regarding the use of social media to foster organ transplantation. We provide an ethical framework to guide transplant stakeholders in using social media for public and patient communication about transplantation and living donation, and offer recommendations for transplant clinical practice and future research. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  1. Noninvasive absolute cerebral oximetry with frequency-domain near-infrared spectroscopy

    NASA Astrophysics Data System (ADS)

    Hallacoglu, Bertan

    Near-infrared spectroscopy (NIRS) measurements of absolute concentrations of oxy-hemoglobin and deoxy-hemoglobin in the human brain can provide critical information about cerebral physiology in terms of cerebral blood volume, blood flow, oxygen delivery, and metabolic rate of oxygen. We developed several frequency domain NIRS data acquisition and analysis methods aimed at absolute measurements of hemoglobin concentration and saturation in cerebral tissue of adult human subjects. Extensive experimental investigations were carried out in various homogenous and two-layered tissue-mimicking phantoms, and biological tissues. The advantages and limitations of commonly used homogenous models and inversion strategies were thoroughly investigated. Prior to human subjects, extensive studies were carried out in in vivo animal models. In rabbits, absolute hemoglobin oxygen desaturation was shown to depend strongly on surgically induced testicular torsion. Methods developed in this study were then adapted for measurements in the rat brain. Absolute values were demonstrated to discern cerebrovascular impairment in a rat model of diet-induced vascular cognitive impairment. These results facilitated the development of clinically useful optical measures of cerebrovascular health. In a large group of human subjects, employing a homogeneous model for absolute measurements was shown to be reliable and robust. However, it was also shown to be limited due to the relatively thick extracerebral tissue. The procedure we develop in this work and the thesis thereof performs a nonlinear inversion procedure with six unknown parameters with no other prior knowledge for the retrieval of the optical coefficients and top layer thickness with high accuracy on two-layered media. Our absolute measurements of cerebral hemoglobin concentration and saturation are based on the discrimination of extracerebral and cerebral tissue layers, and they can enhance the impact of NIRS for cerebral hemodynamics and

  15. Hemodynamic Intervention of Cerebral Aneurysms

    NASA Astrophysics Data System (ADS)

    Meng, Hui

    2005-11-01

    Cerebral aneurysm is a pathological vascular response to hemodynamic stimuli. Endovascular treatment of cerebral aneurysms essentially alters the blood flow to stop them from continued growth and eventual rupture. Compared to surgical clipping, endovascular methods are minimally invasive and hence rapidly gaining popularity. However, they are not always effective with risks of aneurysm regrowth and various complications. We aim at developing a Virtual Intervention (VI) platform that allows: patient-specific flow calculation and risk prediction as well as recommendation of tailored intervention based on quantitative analysis. This is a lofty goal requiring advancement in three areas of research: (1). Advancement of image-based CFD; (2) Understanding the biological/pathological responses of tissue to hemodynamic factors in the context of cerebral aneurysms; and (3) Capability of designing and testing patient-specific endovascular devices. We have established CFD methodologies based on anatomical geometry obtained from 3D angiographic or CT images. To study the effect of hemodynamics on aneurysm development, we have created a canine model of a vascular bifurcation anastomosis to provide the hemodynamic environment similar to those in CA. Vascular remodeling was studied using histology and compared against the flow fields obtained from CFD. It was found that an intimal pad, similar to those frequently seen clinically, developed at the flow impingement site, bordering with an area of `groove' characteristic of an early stage of aneurysm, where the micro environment exhibits an elevated wall shear stresses. To further address the molecular mechanisms of the flow-mediated aneurysm pathology, we are also developing in vitro cell culture systems to complement the in vivo study. Our current effort in endovascular device development focuses on novel stents that alters the aneurysmal flow to promote thrombotic occlusion as well as favorable remodeling. Realization of an

    Children with cerebral palsy (CP) have complex health-care needs. This study examines levels of parental satisfaction with inpatient care for children with CP at a tertiary care hospital to identify areas for improvement. Parents/guardians of children with CP and parents/guardians of children without a disability admitted to hospital completed a custom-designed questionnaire assessing six areas of the hospital admission: (i) the admission process; (ii) the child's personal care; (iii) the child's medical care; (iv) overall care of the child; (v) the parent's experience in hospital; and (vi) keeping up to date in hospital. Differences between the two groups were analysed using Student's t-tests. Parents of children with CP were significantly less satisfied with the inpatient care as compared with parents of children without a disability in four of the six categories: 'my child's personal care' (P = 0.0033), 'my child's medical care' (P = 0.0350), 'overall care' (P = 0.0081) and 'my experience in the hospital' (P = 0.0209). When the overall questionnaire was compared between the two groups, parents of children with CP were less satisfied with care than parents of children without a disability (P = 0.0036). Parents of children with CP are less satisfied with the inpatient care of their child compared with parents of children without a disability. This information should be instrumental in informing change to ensure that parent satisfaction levels improve to a level consistent with other children admitted to a tertiary care setting. © 2015 The Authors.

    2012-01-01

    Cerebral asymmetry is used to describe the differences in electroencephalographic activity between regions of the brain. The objective of this study was to document frontal, central, and parietal asymmetry in psychophysiological (Psy-I) and paradoxical (Para-I) insomnia sufferers as well as good sleeper (GS) controls, and to compare their patterns of asymmetry to others already found in anxiety and depression. Additionally, asymmetry variations between nights were assessed. Participants were 17 Psy-I, 14 Para-I, and 19 GS (mean age = 40 years, SD = 9.4). They completed three nights of polysomnography (PSG) recordings following a clinical evaluation in a sleep laboratory. All sleep cycles of Nights 2 and 3 were retained for power spectral analysis. The absolute activity in frequency bands (0.00-125.00 Hz) was computed at multiple frontal, central, and parietal sites in rapid eye movement and non-rapid eye movement sleep to provide cerebral asymmetry measures. Mixed model ANOVAs were computed to assess differences between groups and nights. Correlations were performed with asymmetry and symptoms of depression and anxiety from self-reported questionnaires. Over the course of the two nights, Para-I tended to present hypoactivation of their left frontal region but hyperactivation of their right one compared with GS. As for Psy-I, they presented increased activation of their right parietal region compared with Para-I. Asymmetry at frontal, central, and parietal region differed between nights. On a more disrupted night of sleep, Psy-I had increased activity in their right parietal region while Para-I presented a decrease in cerebral activity in the right central region on their less disrupted night of sleep. Anxious and depressive symptoms did not correlate with asymmetry at any region. Therefore, Psy-I and Para-I present unique patterns of cerebral asymmetry that do not relate to depression or anxiety, and asymmetry varies between nights, maybe as a

    Hyponatremia is the most frequent electrolyte disorder in critically neurological patients. Cerebral salt wasting syndrome (CSW) is defined as a renal loss of sodium during intracranial disease leading to hyponatremia and a decrease in extracellular fluid volume. The pathogenesis of this disorder is still not completely understood. Sympathetic responses as well as some natriuretic factors play a role in this syndrome. Distinction between SIADH and CSW might be difficult. The essential point is the volemic state. It is necessary to rule out other intermediate causes. Treatment requires volume replacement and maintenance of a positive salt balance. Mineral corticoids may be useful in complicated cases.

    A nine year old domestic shorthair cat was presented to the Small Animal Clinic, Ontario Veterinary College, with anorexia, depression and blindness. The animal died despite treatment. At necropsy, a space occupying mass was located in the left cerebral hemisphere. Histopathologically, the mass consisted of large numbers of fungal yeast-phase cells with an associated pyogranulomatous inflammatory response. The organisms were identified as Blastomyces dermatitidis on the basis of morphology and staining characteristics. The purpose of this article is to describe the lesions of blastomycosis in the brain of a cat. ImagesFigure 1.Figure 2.Figure 3. PMID:17422472

    A 38-year-old woman with a history of a granulomatous lesion of the nose, developed blurred vision, ataxic gait, and spastic tetraparesis. The presence of demyelination on the brain MRI led to the diagnosis of cerebral demyelination associated with Wegener's granulomatosis. Pulse cyclophosphamide administration resulted in some clinical of improvement of her condition. Demyelinating lesions seen in Wegener's have been ascribed to multiple sclerosis, but in this case, they are much more reminiscent of disseminated encephalomyelitis (DEM). The immunological challenge of the underlying disease, may, in the genetically susceptible person, presumably trigger the appearance of MS lesions. Wegener's granulomatosis must be considered in the differential diagnosis of MS.
