A prospective study of posttraumatic epilepsy
Clinical, EEG and neuroimaging data obtained from 4 serial assessments from the acute phase to one year later in 104 head injured adult patients were used for a prospective study of risk factors for post-traumatic epilepsy. Severe or moderate head injuries (HI) were prevalent among the entire group (68.3%) in which early seizures (ES) occurred in 9.4% and late seizures (LS) in 17.3%. Crises were considered LS when they occurred after 4 weeks from HI. Coma duration, ES: temporal lobe lesions shown by CT in the acute traumatic phase and focal gliosis with or without haemosiderin shown by MRI one year later were significantly prevalent in patients with LS who also developed an early slow wave or epileptiform EEG focus in significantly higher percentages than patients without LS. Moreover, the EEG focus preceded the first late seizure with a mean time interval of one month
Serum free carnitine levels in epileptic children on valproic acid
3rd European Congress of Epileptology -- MAY 24-28, 1998 -- WARSAW, POLANDWOS: 000077228300006This study was carried out in a multipupose-based design to evaluate serum-free carnitine (SFC) levels in epileptic children. In a three-stage model, we sought to determine (a) SFC levels in epileptic patients receiving Valproic acid (WA) or other antiepileptic drugs for at least sir months, (b) on a longitudinal basis, WA-induced alterations in SFC levels in new cases given VPA therapy, and (c) whether decreased SFC levels were associated with detoriation in myocardial and respiratory functions and whether and to what extent use of L-carnitine supplementation would be justified to counter the presumable myocardial dysfunction. For determining SFC levels, all the samples were studied using enzymatic-calorimetric method Mean SFC level in each study group (monotherapy with VPA, polytherapy with VPA, and other antiepileptic group) showed significant depressed level from that of the control group (p 0.05), except for significantly increased posttreatment vital capacity (VC) (p< 0.05). Bat pretreatment VC levels were not lower than normal. In conclusion, patients presenting with decreased SFC levels following prolonged administration of WA or other antiepileptic drugs are not likely to experience some significant clinical problems as to merit L-carnitine supplementation.Int League Against Epileps
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
In this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
Carnitine insufficiency in sodium valproate monotherapy
3rd European Congress of Epileptology -- MAY 24-28, 1998 -- WARSAW, POLANDWOS: 000077228300031It is well known that in patients having NaV therapy, hyperammonemia with carnitine deficiency is frequently observed. In this study, 25 cases (IO male, 15 female; mean age:23) receiving NaV monotherapy for an average of three years; has been given 15 mg/kg carnitine for one month period. At the beginning and at the end of the first month of the therapy the levels of plasma carnitine. ammonium and serum transaminases has been measured. Also patients echocardiogram (ECHO), and electrocardiograms (ECG) were carried out. The results;were compared with the results of 23 normal cases within the same age group. Before the treatment, serum level of NaV was found to be 57.11 mu gr/ml. At the same time carnitine serum level was 5.35 mg/L. NH3's was 41.92 mu mol/ml. At the end of the first month of the therapy; serum level of NaV: 63.67 mu gr/ml, level of carnitine: 9.46 mg/L and NH3 level was found to be 15.95 mu mol/ml, respectively, After treatment a non significant increase in NaV serum level was observed (p:0.207). On the other hand, the increase in plasma level of carnitine (p:0.000), and the reduction in NH3 level (p:0.01) were statistically significant. There were no difference between ECHO and ECG findings before and after treatment which were all within normal limits. The serum level of NaV, the dosage and the period of drug usage did not affect the serum levels of NaV and carnitine. When compared with normal control group, epileptic patients in NaV treatment were determined to have lower serum carnitine levels, and significantly higher serum NH3 levels. Our clinical trial have shown that in epileptic patients treated with NaV; serum carnitine levels decrease, NH, levels increase; and these changes in the body could be repaired by adding carnitine to treatment.Int League Against Epileps
