Intracranial haemorrhage associated with cerebral infections: A review
No full textWe present a review of the different viral, bacterial, parasitic and fungal infections that are associated with intracranial haemorrhages. We summarize the clinical presentation of the infection and its cerebral complication. We elucidate the pathology and pathophysiology of the haemorrhage as being spontaneous or secondary to vasculitis, thrombosis, embolization or aneurysmal formation. © 2011 Informa Healthcare.AKE JA, 2006, CLIN INFECT DIS, V43, P46; ARGYRIOU A, 2006, SCAND J INFECT DIS, V1, P63; Boudewijns M, 2003, CLIN MICROBIOL INFEC, V9, P222, DOI 10.1046-j.1469-0691.2003.00503.x; BURKE JM, 1985, NEUROLOGY, V35, P1368; Chan KH, 2005, CEREBROVASC DIS, V19, P391, DOI 10.1159-000085568; Chehrenama M, 1997, NEUROLOGY, V48, P520; Chukwudelunzu FE, 2002, EUR J NEUROL, V9, P423, DOI 10.1046-j.1468-1331.2002.00432.x; Cole JW, 2004, STROKE, V35, P51, DOI 10.1161-01.STR.0000105393.57853.11; Connor MD, 2000, STROKE, V31, P2117; DASTUR DK, 1995, RADIOL CLIN N AM, V33, P733; Dubrovsky T, 1998, NEUROLOGY, V51, P560; ELKIND M, 2010, ARCH NEUROL-CHICAGO, V67, pE1; Endo T, 2002, NEUROSURGERY, V50, P1147, DOI 10.1097-00006123-200205000-00039; Erly WK, 1999, AM J NEURORADIOL, V20, P1605; Flint AC, 2005, NEUROLOGY, V64, P391; Gall C, 1999, NEW ENGL J MED, V341, P611, DOI 10.1056-NEJM199908193410814; Gautschi O, 2003, RESPIRATION, V70, P419, DOI 10.1159-000072908; Gkrania-Klotsas Effrossyni, 2008, J Med Case Rep, V2, P387, DOI 10.1186-1752-1947-2-387; Grau AJ, 2005, STROKE, V36, P1501, DOI 10.1161-01.STR.0000170674.45136.80; Heiro M, 2000, ARCH INTERN MED, V160, P2781, DOI 10.1001-archinte.160.18.2781; Hofer M, 2005, ACTA NEUROPATHOL, V109, P226, DOI 10.1007-s00401-004-0930-3; Jacobi C, 2006, EUR J NEUROL, V13, P536, DOI 10.1111-j.1468-1331.2006.01335.x; Jain R, 2003, AM J NEURORADIOL, V24, P971; Kannoth S, 2009, NEUROCRIT CARE, V11, P120, DOI 10.1007-s12028-009-9208-x; KAYA S, 2008, NEUROSURG REV, V1, P337; KIKUTA H, 1993, BLOOD, V82, P3259; KURE K, 1989, Pediatric Pathology, V9, P655; Lim KK, 2009, J CLIN NEUROSCI, V16, P140, DOI 10.1016-j.jocn.2008.02.017; Maniker AH, 1996, SURG NEUROL, V46, P49, DOI 10.1016-0090-3019(96)00030-4; MCGUIRE D, 1999, AIDS KNOWLEDGE BASE, P445; Miyamoto S, 2006, NEUROL MED-CHIR, V46, P348, DOI 10.2176-nmc.46.348; Mochan A, 2003, STROKE, V34, P10, DOI 10.1161-01.STR.0000043821.35051.FA; Modi G, 2008, J NEUROL NEUROSUR PS, V79, P44, DOI 10.1136-jnnp.2006.108878; MUHPATRA AK, 1988, J ASSOC PHYSICIAN I, V36, P237; MURUGAVEL K, 1989, POSTGRAD MED J, V65, P236; Nigro G, 2002, PRENATAL DIAG, V22, P558, DOI 10.1002-pd.366; Ortiz JU, 2004, ULTRASOUND OBST GYN, V23, P402, DOI 10.1002-uog.1021; Pinto AN, 1996, STROKE, V27, P538; Piovesan EJ, 1997, ARQ NEURO-PSIQUIAT, V55, P126; Rich AR, 1933, B JOHNS HOPKINS HOSP, V52, P5; Scheid R, 2003, EUR J NEUROL, V10, P99, DOI 10.1046-j.1468-1331.2003.00541.x; SCULLY RE, 1996, NEW ENGL J MED, V335, P1587; SNIDER WD, 1983, ANN NEUROL, V14, P403, DOI 10.1002-ana.410140404; Sundaram C, 2007, J CLIN NEUROSCI, V14, P882, DOI 10.1016-j.jocn.2006.05.014; Takeda H, 2002, NEUROL MED-CHIR, V42, P361, DOI 10.2176-nmc.42.361; Uesugi T, 2006, INTERNAL MED, V45, P1193, DOI 10.2169-internalmedicine.45.6116; Vejjajiva A, 1978, Clin Exp Neurol, V15, P92; WIJDICKS EFM, 1991, ANN NEUROL, V29, P683, DOI 10.1002-ana.410290620; Yanagihara C, 2003, INTERNAL MED, V42, P1244, DOI 10.2169-internalmedicine.42.1244; Yeh STY, 2003, J EMERG MED, V25, P265, DOI 10.1016-S0736-4679(03)00200-2; Yoneda H, 2005, CEREBROVASC DIS, V19, P209, DOI 10.1159-00008388422
Sarcoidosis associated with neuromyelitis optica
No full textNeuromyelitis optica (NMO) is an autoimmune disorder diagnosed by an elongated spinal cord lesion associated with unilateral or bilateral optic neuritis and anti-aquaporin 4 (AQP4) antibodies in the serum. It is triggered by or associated with several autoimmune diseases, but not with sarcoidosis. It responds to immunomodulators better than to steroid treatment. Sarcoidosis is an autoimmune disorder which manifests as non-caseating granulomas, usually in the lung parenchyma, but also in other tissues, including the brain. The involvement of the central nervous system in neurosarcoidosis differs considerably from that in neuromyelitis optica and the association of these two diseases concurrently in the same patient is unusual. © 2013 Elsevier Ltd.

Song listening does not affect pattern reversal visual evoked potentials
No full textBACKGROUND AND OBJECTIVE: The pattern reversal visual evoked response has been defined as a reproducible cortical response upon stimulation of the eyes. This response depends on the intensity of the light stimulus and its distance from the eyes and is not affected by simultaneous tactile or auditory stimulation. However, in some patients we observe different P100 latencies, at different intervals of testing, without lesions of the optic tracts. The purpose of this study was to evaluate whether a loud meaningful acoustic noise, simulated by song listening, during the testing of the visual evoked response, could alter the latency or amplitude of the cortical potentials. DESIGN AND SETTING: The study was performed in the Clinical Neurophysiology Laboratory of the Medical Center by one technician trained to perform visual evoked potential analysis. SUBJECTS AND METHODS: We performed pattern reversal visual evoked potentials on 40 eyes of normal individuals at rest and during auditory stimulation with loud meaningful acoustic noise in the form of songs familiar to the subject. We compared the latencies and amplitudes of the P100 wave during these two test conditions. RESULTS: The latencies and amplitudes of the P100 waves evoked upon stimulation of the eyes of the subjects did not differ statistically during the test at rest and upon stimulation with songs simulating loud acoustic noise. Conclusions: We conclude that loud song listening has no effect on the pattern reversal visual evoked potential latency or amplitude. Thus, it seems likely that the results are independent of environmental acoustic noise.Amezcua C, 2005, INT J NEUROSCI, V115, P193, DOI 10.1080-0020745090519094; Avitabile T, 2007, CURR EYE RES, V32, P999, DOI 10.1080-02713680701679006; Chiappa KH, 1989, EVOKED POTENTIALS CL, P37; Coppola G, 2007, EUR J OPHTHALMOL, V17, P828; De Marinis M, 2007, HEADACHE, V47, P895, DOI 10.1111-j.1.526-4610.2007.00774.x; Durukan AH, 2006, DOC OPHTHALMOL, V112, P23, DOI 10.1007-s10633-006-0001-2; Heinrich SP, 2007, J VISION, V7, DOI 10.1167-7.6.6; Kimura M, 2005, NEUROREPORT, V16, P2061, DOI 10.1097-00001756-200512190-00019; Koivisto M, 2007, NEUROREPORT, V18, P753, DOI 10.1097-WNR.0b013e3280c143c8; Ozmerdivenli R, 2005, INT J NEUROSCI, V115, P1043, DOI 10.1080-002074505909084841; Patston LLM, 2007, NEUROPSYCHOLOGIA, V45, P2059, DOI 10.1016-j.neuropsychologia.2007.02.001; Spreafico C, 2004, NEUROL SCI, V25, pS288, DOI 10.1007-s10072-004-0313-5; Talsma D, 2007, CEREB CORTEX, V17, P679, DOI 10.1093-cercor-bhk0160
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
