    Childhood neuroblastic tumors are characterized by heterogeneous clinical courses, ranging from benign ganglioneuroma (GN) to highly lethal neuroblastoma (NB). Although a refined prognostic evaluation and risk stratification of each tumor patient is becoming increasingly essential to personalize treatment options, currently only few biomolecular markers (essentially MYCN amplification, chromosome 11q status and DNA ploidy) are validated for this purpose in neuroblastic tumors. Here we report that Galectin-3 (Gal-3), a β-galactoside-binding lectin involved in multiple biological functions that has already acquired diagnostic relevance in specific clinical settings, is variably expressed in most differentiated and less aggressive neuroblastic tumors, such as GN and ganglioneuroblastoma, as well as in a subset of NB cases. Gal-3 expression is associated with the INPC histopathological categorization (P<0.001) and Shimada favorable phenotype (P=0.001), but not with other prognostically relevant features. Importantly, Gal-3 expression was associated with a better 5-year overall survival (P=0.003), and with improved cumulative survival in patient subsets at worse prognosis, such as older age at diagnosis, advanced stages or NB histopathological classification. In vitro, Gal-3 expression and nuclear accumulation accompanied retinoic acid-induced cell differentiation in NB cell lines. Forced Gal-3 overexpression increased phenotypic differentiation and substrate adherence, while inhibiting proliferation. Altogether, these findings suggest that Gal-3 is a biologically relevant player for neuroblastic tumors, whose determination by conventional immunohistochemistry might be used for outcome assessment and patient's risk stratification in the clinical setting. © 2014 Macmillan Publishers Limited All rights reserved

    Wearing-off detection in clinical practice: The wearing off real practice key (WORK-PD) study in Parkinson's disease

    Objective: Verifying the validity and feasibility of the WOQ-19 as a useful tool in routine clinical practice and in management of patients. Methods: 532 consecutive Parkinson's disease (PD) patients were recruited from 6 different neurological outpatient units, specialized in movement disorders, of central Italy. Inclusion criteria were diagnosis of PD and any current pharmacological treatment of PD while exclusion criteria were evident cognitive or depressive impairment, infusion with dopamine agonists or Duodopa, or Deep Brain Stimulation therapy. Patients were asked to complete the Italian version of WOQ-19 before the neurological visit. A medical form for the collection of demographic and clinical data of patients and for the evaluation of comprehensibility and usability the WOQ-19 was filled by the neurologist during the visit. Results: Our data confirmed that WOQ-19 was able to identify WO in 69% of patients, a percentage similar to the recently reported in the Italian WOQ-19 validation study. Motor symptoms were more frequent than non-motor symptoms (80% vs. 20%). Patients who experienced WO had a higher age of PD onset, more severe disease, longer disease duration and were more likely to be female. Conclusions: The WOQ-19 was understandable for the patient, easily administered and suitable for routine outpatient use. It could be also particularly useful in clinical practice in the early identification of non-motor symptoms, often under reported by patients and revealed only with clinical support

    21noBackground and aim: In the scientific literature, there is unanimous consensus that hospitalization in stroke unit (SU) is the most important treatment for stroke patients. In this regard, the Act number 70/2015 by the Italian government identified specific skills that contribute to a classification of SU and outlined a “hub and spoke” stroke network. The aim of our study was to check the coverage of requirements of first and second level SU in the national territory and to shed light on any deficit or misdistribution of resources. Material and methods: In 2019, a survey on the current situation related to stroke care in Italy was carried out by the Italian Society of Neurology (SIN), The Italian Stroke Organization (ISO), and the Association for the Fight against Stroke (A.L.I.Ce). Results: First level SU was found to be 58 against a requirement, according to the Act 70/2015, of 240. Second level SU was found to be 52 compared with an expected requirement of 60. Neurointerventionists were 280 nationally, with a requirement of 240. A misdistribution of resources within individual regions was often seen. Conclusions: The survey demonstrated a severe shortage of beds dedicated to cerebrovascular diseases, mainly because of lack of first level SU, especially in central and southern Italy. It also suggests that the current hub and spoke system is not yet fully implemented across the country and that resources should be better distributed in order to ensure uniform and fair care for all stroke patients on the whole territory.openopenBandettini di Poggio M.; Toni D.; Gandolfo C.; Paolicelli D.; Zini A.; Agostoni E.; Bandini F.; Ragno M.; Altavista M.C.; Bertolotto A.; Siciliano G.; Vecchio M.; Tambasco N.; Gambardella A.; Manganotti P.; Melis M.; Onofrj M.; De Michele G.; Reale N.; Tedeschi G.; Mancardi G.L.Bandettini di Poggio, M.; Toni, D.; Gandolfo, C.; Paolicelli, D.; Zini, A.; Agostoni, E.; Bandini, F.; Ragno, M.; Altavista, M.

    Extended release levodopa at bedtime as a treatment for nocturiain Parkinson's disease: an open label study

    No full text
    Bladder dysfunction may cause disabling symptoms in Parkinson's disease (PD) patients. The majority patients' experience symptoms as urinary urgency and nocturia suggest overactive bladder. This seems to be due to an altered brain-bladder relationship because of alteration in fronto-basal ganglia D1-dopaminergic circuit that normally suppresses micturition-reflex. Previous studies demonstrated beneficial effect of D1/D2 dopamine-receptors chronic-stimulation on detrusor overactivity of PD-patients.The present study was aimed to evaluate possible effect of extended-release (ER) Levodopa administered at bed-time on both nocturia and nocturia-related quality-of-life (NQoL) in PD-patients

    We report the case of a man who developed unilateral alternating chorea four years before presenting a typical clinical form of Steele-Richardson-Olszewski syndrome. It is known that choreic dyskinesias may occur during the course of this syndrome but this is the first account of choreas presenting sign of the syndrome

    Sudden Onset, Fixed Dystonia and Acute Peripheral Trauma as Diagnostic Clues for Functional Dystonia

    No full text
    Background: The differentiation of functional dystonia from idiopathic dystonia may be clinically challenging. Objective: To identify clinical features suggestive of functional dystonia to guide physicians to distinguish functional dystonia from idiopathic dystonia. Methods: Patient data were extracted from the Italian Registry of Functional Motor Disorders and the Italian Registry of Adult Dystonia. Patients with functional and idiopathic dystonia were followed up at the same clinical sites, and they were similar in age and sex. Results: We identified 113 patients with functional dystonia and 125 with idiopathic dystonia. Sudden onset of dystonia, evidence of fixed dystonia, and acute peripheral trauma before dystonia onset were more frequent in the functional dystonia group. No study variable alone achieved satisfactory sensitivity and specificity, whereas a combination of variables yielded 85% sensitivity and 98% specificity. A diagnostic algorithm was developed to reduce the risk of misclassifying functional dystonia. Conclusion: Our findings extend the current diagnostic approach to functional dystonia by showing that clinical information about symptom onset, fixed dystonia, and history of peripheral trauma may provide key clues in the diagnosis of functional dystonia
