Cytosine arabinoside (Ara-C) is one of the key drugs for treating acute myeloid leukemia (AML). High intravenous doses may produce a number of central nervous system (CNS) toxicities and contribute to modifications in brain functional connectivity. sLORETA is a software used for localizing brain electrical activity and functional connectivity. The aim of this study was to apply sLORETA in the evaluation of possible effects of Ara-C on brain connectivity in patients with AML without CNS involvement. We studied eight patients with AML; four were administered standard doses of Ara-C while the other four received high doses. sLORETA was computed from computerized EEG data before treatment and after six months of treatment. Three regions of interest, corresponding to specific combinations of Brodmann areas, were defined. In the patients receiving high-dose Ara-C, a statistically significant reduction in functional connectivity was observed in the fronto-parietal network, which literature data suggest is involved in attentional processes. Our data highlight the possibility of using novel techniques to study potential CNS toxicity of cancer therapy.

The term frontotemporal lobar degeneration (FTLD) describes a spectrum of neurodegenerative disorders associated with deposition of misfolded proteins in the frontal and temporal lobes. Up to 40% of FTLD patients reports a family history of neurodegeneration, and approximately 1/3 of familial cases shows an autosomal dominant pattern of inheritance of the phenotype. Over the past two decades, several causative and susceptibility genes for FTLD have been discovered, supporting the notion that genetic factors are important contributors to the disease processes. Genetic variants in three genes, MAPT, GRN and C9orf72, account for about half of familial FTLD cases. In addition, rare defects in the CHMP2B, VCP, TARDBP, SQSTM1, FUS, UBQLN, OPTN, TREM2, CHCHD10 and TBK1 genes have been described. Additional genes are expected to be found in near future. The purpose of this review is to describe recent advances in the molecular genetics of the FTLD spectrum and to discuss implications for genetic counseling.

To date, medical education lacks Europe-wide standards on neurorehabilitation. To address this, the European Federation of NeuroRehabilitation Societies (EFNR) here proposes a postgraduate neurorehabilitation training scheme. In particular, the European medical core curriculum in neurorehabilitation should include a two-year residency in a neurorehabilitation setting where trainees can gain practical experience. Furthermore, it should comprise six modules of classroom training organized as weekend seminars or summer/winter schools. In conclusion, after defining the European medical core curriculum in neurorehabilitation, the next activities of the EFNR will be to try and reach the largest possible consensus on its content among all national societies across Europe in order to further validate it and try to extend it to the other, non-medical, professionals on the neurorehabilitation team in line with their core curricula defined by each professional association.

This study aimed to characterize the coefficient of friction (COF) curves of patients with Parkinson's disease (PD) during barefoot gait and to evaluate the relationships between this variable and functional scales. Twenty-two subjects with PD (ON phase of levodopa) and 22 healthy subjects participated in this study. The participants walked barefoot along a pathway that went over two force plates embedded in the floor of the data collection room. The instantaneous COF was calculated as the ratio between the horizontal and vertical components of the ground reaction forces. Two-sample t-tests applied to every 1% of the support phase of the COF curve were used to compare the groups and to identify the phases in which the two groups were different. Specifically, three COF areas were computed: Area 1 (for the loading response phase), Area 2 (for the midstance phase) and Area 3 (for the terminal stance phase). Pearson's tests were applied to assess the associations between the COF curve areas and the clinical scales. The subjects with PD exhibited lower COF values during the loading response and terminal stance phases and higher COF values during the mid-stance phase compared with the control group. A strong positive correlation was observed between Area 1 and the Timed Up and Go Test (90.3%). In conclusion, the patients' COFs exhibited patterns that were different from those of the control group. Moreover, during the loading response phase, these differences were well-correlated with the Timed Up and Go Test scale data; Timed Up and Go Test data can be used to identify the risk of falls among PD patients.

The present national survey seeking to identify unmet needs in the management of spasticity with botulinum toxin type A focused on the use of OnabotulinumoxinA, since this is the brand with the widest range of licensed indications in Italy. Physicians from twenty-four Italian neurorehabilitation units compiled a questionnaire about "real-life" post-stroke spasticity management. OnabotulinumtoxinA was reported to be used in the following average doses: upper limb 316.7 ± 79.1 units; lower limb 327.8 ± 152.3; upper and lower limb 543.7 ± 123.7 units. Of the physicians surveyed, 37.5% felt that increasing the frequency of OnabotulinumtoxinA injection would improve its efficacy; 70.8% use electrical stimulation/electromyography guidance (one fourth of injections with no instrumental guidance). Instrumental evaluation was used by 41.7% of the physicians. The participants expressed the view that early identification of post-stroke spasticity would be facilitated by the availability of a post-stroke checklist, and that this should be used by physiotherapists (91.7%), physiatrists (58.3%), family doctors (50%), stroke unit physicians (25%), patients and caregivers (79.2%). According to our findings, the management of poststroke spasticity has several unmet needs that, were they addressed, might improve these patients' clinical outcomes and quality of life. These needs concern patient follow-up, where a clearly defined pathway is lacking; furthermore, there is a need to use maximum doses per treatment and to ensure early intervention on post-stroke spasticity.

Takotsubo cardiomyopathy (TTS) is a peculiar clinical condition often affecting postmenopausal women after a stressful trigger. The underlying mechanisms have not been completely elucidated but several hypotheses have been advanced, with catecholamine cardiotoxicity, microvascular dysfunction and coronary artery spasm each suggested to play a role. The incidence of stroke after TTS appears to range from 0% to 7.7%, and interestingly TTS has been described as both a cause and a complication of stroke. We sought to assess the incidence and predictors of stroke during the index event (peri-index event stroke) in a heterogeneous TTS population. We conducted a retrospective descriptive study reviewing patients who were discharged with a diagnosis of TTS from the Einstein Medical Center, Philadelphia, PA and Danbury Hospital, Danbury, CT in the period between 2003 and 2014. A total of Incidence and predictors of stroke during the index event in an ethnically diverse Takotsubo cardiomyopathy population 206 patients met the modified Mayo Clinic criteria and were included in the study. The patients' overall mean age was 67.8 years; 87% (n=179) were females and 25% (n=53) were African Americans. The following incidence rates were found: stroke 7%, in-hospital heart failure 26.7%, and in-hospital death 7%. On multivariate analysis independent predictors (expressed as odds ratios with 95% confidence intervals) of periindex event stroke were: i) African American race (OR 3.2, 95% CI 1.2-10.2, p=0.048); ii) hypertension (OR 10.5, 95% CI 1.3-88, p=0.03). ACE inhibitor use was a protective factor for developing peri-index event stroke (OR 0.15, 95% CI 0.04-0.5, p=0.001). There was a trend towards dual antiplatelet therapy (DAPT) being protective for stroke (OR 0.3, 95% CI 0.05-1.1, p=0.08). The incidence of peri-index event stroke was 7%. African American race and hypertension were found to be independent predictors of peri-index event stroke. Prospective clinical trials are needed to confirm these findings and to better determine the impact of hypertension as a risk factor for stroke and to assess the role of DAPT in preventing it.

The authors set out to examine qualitatively the use of antiepileptic drugs (AEDs) in a population of older adults in a nursing home setting, evaluating aspects such as specialist prescriptions and changes in dosage. This retrospective prevalence study was carried out in a state-funded nursing home that provides care and rehabilitation for elderly people. The first objective of the study was to determine the prevalence of AED use in this population. The second objective was to monitor AED dosage modifications during the fifteen-month study period, focusing on the safety and the tolerability of AEDs. In the period of time considered, 129 of 402 monitored patients received at least one anti-epileptic therapy. The prevalence of AED use was therefore 32%. Gabapentin was found to be the most commonly prescribed drug, with a frequency of 29%, and it was used mainly for anxiety disorders, psychosis, neuropathic pain and mood disorders.
