Plasmapheresis in a child affected by acute disseminated encephalomyelitis
No full textWe describe an eight year old girl with acute relapsing disseminated encephalomyelitis (ADEM) who began to improve concomitantly with plasmapheresis therapy. The patient had previously undergone high-dose intravenous methylprednisolone, intravenous immunoglobulins and Interferon beta-lb treatment which did not control the clinical course of the disease. The long term follow-up suggests that plasmapheresis is effective in this disorder and may give better results than steroids or IVIG. (C) 2000 Elsevier Science B.V. All rights reserved

No full textBody mass index and serum lipid changes during treatment with valproic acid in children with epilepsy
No full textBACKGROUND: Valproic acid is the drug of choice for a wide variety of epileptic seizures and syndromes because of its broad spectrum of activity and because, in most patients, it is well tolerated. Although weight gain is a well-known adverse effect of valproic acid therapy, only a few studies have addressed weight gain associated with it in children aged 2-8 years.
OBJECTIVE: To evaluate valproic acid-associated changes in the body mass index (BMI) z-scores and to assess changes in serum triglyceride, cholesterol, and fasting glucose levels in young children receiving valproic acid treatment.
METHODS: Eighty-seven patients (39 females, 48 males) receiving valproic acid therapy for at least 3 months were included in the retrospective longitudinal study. Mean +/- SD age at initiation of therapy was 4.8 +/- 0.8 years. Changes in BMI z-scores as well as serum triglyceride, total cholesterol, and fasting glucose levels were evaluated as continuous variables and analyzed by longitudinal methods for all patients.
RESULTS: The average change from baseline in BMI z-scores was 0.80 (p 0.001) at 3.1 years of follow-up. No significant change in triglyceride, cholesterol, and serum fasting glucose levels was observed over the same period. The percentage of overweight children at baseline was 6.9% and rose to 16% by the final visit (p = 0.081).
CONCLUSIONS: Valproic acid-associated weight gain may occur in young children. However, only 16% of patients were categorized as overweight at the end of the study; this percentage overlaps the percentage of overweight healthy young Italian children. The BMI z-scores significantly increased during the first 16 months of therapy, then appeared to level off. These observations may influence clinical practice and decision-making regarding suspending the drug due to weight gain in children in whom seizure control has been achieved
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
