Abstract

Background: To assess Guillain-Barré syndrome (GBS) incidence we relied on the Italian Network for the study of GBS (ITANG) established in 2010 in 7 Italian regions to analyse the association between influenza vaccination and GBS. Methods: All individuals aged ≥18 years, presenting with clinical manifestations that suggested GBS according to the universally accepted Asbury's diagnostic criteria (1990) were prospectively notified to a centralised database by ITANG neurologists over the period October 1, 2010-September 30, 2011. Through a telephone survey, 9 trained interviewers followed up the cases to diagnosis and then for 1 year since hospital discharge. Validation of case reporting was performed with the support of administrative data in 5 regions. Results: We found 365 cases fulfilling the definition for GBS or one of its variants over 19,846,068 population ≥18 years of age, yielding an annual incidence rate of 1.84 per 100,000 (95% CI 1.65-2.03), 2.30 (95% CI 1.99-2.60) in men and 1.41 (95% CI 1.18-1.64) in women. A highly significant peak of incidence was observed in February 2011 as compared to reference month (September 2011, rate ratio 3.3:1, p < 0.01). Conclusions: In Italy, GBS incidence was among the highest reported in Europe and higher than previously observed in Italian studies.

Abstract

l volume raccoglie i contributi della Giornata di studio tenutasi a Padova il 20 marzo 2014 dal titolo "La pittura frammentaria di età romana. Metodi di catalogazione e studio dei reperti", organizzata con l'obiettivo prioritario di presentare ad un pubblico di specialisti le prime fasi del progetto TECT, il cui nome deriva dall'abbreviazione del termine latino tectorium (intonaco), sviluppato al fine di creare una banca dati delle pitture parietali di età romana rinvenute in Italia settentrionale. La "filosofia" del database TECT viene esplicitata nel volume, non solo tramite la presentazione della scheda, ideata nell'ambito del progetto con lo scopo di sistematizzare le evidenze archeologiche (A. Didonè, G. Salvo), ma anche attraverso la proposta di un glossario - pensato per uniformare la descrizione delle testimonianze pittoriche e per facilitarne la ricerca - le cui fasi di elaborazione vengono illustrate in questi atti (R. Helg, A. Malgieri).

Abstract

To evaluate whether botulinum toxin type A at standard doses spreads to antagonist leg muscles in dynamic equinus foot, we studied 18 ambulatory children with hemiplegic cerebral palsy. The gastrocnemius muscle on the affected side was injected with botulinum toxin type A (Dysport) (mean ± standard deviation, 14.3 ± 0.9 U/kg). Compound muscle action potential areas were assessed in the lateral gastrocnemius and tibialis anterior muscles on the treated and untreated sides before botulinum toxin type A injections and on days 10 and 30 after injections. In all patients, compound muscle action potential areas recorded from both the muscles on the treated side decreased from preinjection values at day 10 (P < .05) and 30 (P < .002). After injection, ankle spasticity had diminished (P < .05), equinus foot excursion increased (P < .05), and functional gait improved (P < .05). This study shows that botulinum toxin type A spreads from foot flexors to antagonist extensors and suggests that spread may be partly responsible for improving gait in children with cerebral palsy.

Abstract

Objective: To investigate possible altered CNS excitability in vaginismus., Methods: In 10 patients with primary idiopathic lifelong vaginismus, 10 with vulvar vestibulitis syndrome accompanied by vaginismus and healthy controls we recorded EMG activity from the levator ani (LA) and external anal sphincter (EAS) muscles and tested bulbocavernosus reflex (BCR). Pudendal-nerve somatosensory evoked potentials (SEPs) were tested after a single stimulus. Pudendal-nerve SEP recovery functions were assessed using a paired conditioning-test paradigm at interstimulus intervals (ISIs) of 5, 20 and 40ms., Results: EMG in patients showed muscular hyperactivity at rest and reduced inhibition during straining. The BCR polysynaptic R2 had larger amplitude (p<0.01) and longer duration (p<0.01) in patients from both groups than in controls. In controls, paired-pulse SEPs were suppressed at the 5ms ISI for N35-P40 (p<0.05) and P40-N50 ms (p<0.001) and facilitated at the 20ms ISI for N35-P40 (p<0.05) and P40-N50 (p<0.05). No significant differences were found in the paired-pulse N35-P40 in patients and controls but the cortical P40-N50 at 20 ISI was facilitated in patients (p<0.05)., Conclusions: EMG activity is enhanced and the cortical SEP recovery cycle and BCR are hyperexcitable in vaginismus., Significance: The neurophysiological abnormalities in patients with vaginismus indicate concomitant CNS changes in this disorder.

Abstract

Spasticity leads to functional and structural changes in nerves and muscles, which alter skeletal muscle function. To evaluate whether short-term electrical nerve stimulation (NS) improves the effect of botulinum toxin in spastic skeletal muscle, we studied changes in the amplitude of the compound muscle action potential (CMAP) recorded from the extensor digitorum brevis (EDB) muscle in response to peroneal nerve stimulation at the ankle after injection of botulinum toxin type A (BTXA) alone or combined with short-term NS. In paraparetic patients, both EDB muscles were injected with BTXA; and NS was applied to one EDB muscle alone. All patients received a 30-minute session of electrical NS once a day for 5 consecutive days after BTXA injection. We used two different stimulation frequencies (low-frequency, 4 Hz; and high-frequency, 25 Hz). EDB-CMAP amplitudes were evaluated before BTXA injection (day 0) and changes in CMAP amplitude, expressed as a percentage (CMAP%), were measured at various time points over a 30-day period after BTXA injection. We compared changes in the CMAP% amplitude on the stimulated and contralateral nonstimulated sides. We also studied the electromyographic activity recorded from EDB muscles over a 30-day period. CMAP% amplitudes measured at all time points after BTXA injections were significantly reduced in both EDB muscles. On days 4, 10, and 15, the CMAP% amplitude reduction was significantly greater for the low-frequency stimulated EDB than for the contralateral nonstimulated EDB. No significant differences in CMAP% were observed for the high-frequency stimulated and nonstimulated EDB. After BTXA injection, spontaneous activity appeared in both EDB muscles; but it appeared earlier and involved larger areas in the stimulated than in the nonstimulated EDB. In conclusion, short-term NS accelerates the effectiveness of intramuscular BTXA injections on the neuromuscular blockade in patients with spastic paraparesis and could induce a rapid and persistent improvement in spasticity. Its action probably arises mainly from low-frequency NS., (Copyright 2005 Movement Disorder Society.)

Abstract

The application of DNA microarray technology for analysis of gene expression creates enormous opportunities to accelerate the pace in understanding living systems and identification of target genes and pathways for drug development and therapeutic intervention. Parallel monitoring of the expression profiles of thousands of genes seems particularly promising for a deeper understanding of cancer biology and the identification of molecular signatures supporting the histological classification schemes of neoplastic specimens. However, the increasing volume of data generated by microarray experiments poses the challenge of developing equally efficient methods and analysis procedures to extract, interpret, and upgrade the information content of these databases. Herein, a computational procedure for pattern identification, feature extraction, and classification of gene expression data through the analysis of an autoassociative neural network model is described. The identified patterns and features contain critical information about gene-phenotype relationships observed during changes in cell physiology. They represent a rational and dimensionally reduced base for understanding the basic biology of the onset of diseases, defining targets of therapeutic intervention, and developing diagnostic tools for the identification and classification of pathological states. The proposed method has been tested on two different microarray datasets-Golub's analysis of acute human leukemia [Golub et al. (1999) Science 286:531-537], and the human colon adenocarcinoma study presented by Alon et al. [1999; Proc Natl Acad Sci USA 97:10101-10106]. The analysis of the neural network internal structure allows the identification of specific phenotype markers and the extraction of peculiar associations among genes and physiological states. At the same time, the neural network outputs provide assignment to multiple classes, such as different pathological conditions or tissue samples, for previously unseen instances., (Copyright 2003 Wiley Periodicals, Inc.
