Posterior reversible encephalopathy syndrome in an 87-year-old woman with Escherichia coli bloodstream infection
No full textWe present the case of an 87-year-old woman with history of hypertension,
hypercholesterolemia, ischemic heart diseases, urinary tract infections,
and cerebrovascular disease who experienced a transient clinical picture
characterized by confusion, lethargy, and acute renal dysfunction in the
course of urinary tract infection with Escherichia coli bacteremia.
Escherichia coli bloodstream infection was associated with brain computed
tomography (CT) and magnetic resonance imaging (MRI) patterns in which the
lesion distribution was consistent with posterior reversible encephalopathy
syndrome (PRES). Diagnosis of PRES was confirmed by demonstration of
vasogenic edema on apparent diffusion coefficient (ADC) maps and
near-complete resolution of clinical manifestations at discharge.

Angiomi cavernosi sovratentoriali ed epilessia: Quale terapia?
No full textMost of Authors emphatized the CAs surgical approach. We report twelve cases (7m and 5f) entered into the study upon MRI documentation of supratentorial CAs, neurological examination and EEG. Four have undergone ablative surgery and only 2 have been seizure free. 7 patients under pharmacological treatment alone have undergone a reduction in the frequency and/or severity of epileptic episodes. The present study suggests that CAs surgery is not always reccomended

Supratentorial cavernous angiomas and epilepsy: Which treatment?
No full textCavernous angiomas (CAs) are cerebrovascular malformations most commonly found in investigations of new onset epilepsy. While previously felt to be rare, widespread use of magnetic resonance imaging (MRI) studies reveals a surprisingly high incidence of these lesions, suggesting that CAs may be a frequent cause of epilepsy in the past considered to be of cryptogenic origin. The natural history of CAs is presently poorly understood. The pathogenic potential of these anomalies is still controversial as well as optimal therapeutic strategies for their management. Twelve cases (7 males and 5 females, aged 26-65 years) entered the study upon MRI documentation of supratentorial CAs, neurological examination and EECI. Four have undergone ablative surgery consisting of lesion removal ("lesionectomy") or a larger corticectomy. Of H patients under pharmacological treatment alone, 4 have been seizure-free (for a period ranging from 6 months to 3 years). In contrast, of the 4 surgical patients 2 have been seizure-free, and 2 have undergone a reduction in the frequency and/or severity of epileptic episodes. Therefore, in line with other reports indicating a low incidence of spontaneous bleeding of CAs, the present study suggests that surgery is not always recommended unless there has been a significant clinical hemorrhage and epilepsy can often be successfully managed with anti-epileptic pharmacological treatment. Moreover, the likelihood of relapse of epilepsy in patients who undergo surgical ablation seems to depend mostly upon the frequency, duration of preoperative seizure history and severity of seizures prior to surgery. Thus, surgery for CAs should probably be used only after intensive early evaluation for drug responsiveness in patients who appear unlikely to be adequately managed medically

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
