Abstract
BACKGROUND GENetics of mOyaMoyA (GEN-O-MA) project is a multicenter observational study implemented in Italy aimed at creating a network of centers involved in moyamoya angiopathy (MA) care and research and at collecting a large series and bio-repository of MA patients, finally aimed at describing the disease phenotype and clinical course as well as at identifying biological or cellular markers for disease progression. The present paper resumes the most important study methodological issues and preliminary results. METHODS Nineteen centers are participating to the study. Patients with both bilateral and unilateral radiologically defined MA are included in the study. For each patient, detailed demographic and clinical as well as neuroimaging data are being collected. When available, biological samples (blood, DNA, CSF, middle cerebral artery samples) are being also collected for biological and cellular studies. RESULTS Ninety-eight patients (age of onset mean ± SD 35.5 ± 19.6 years; 68.4% females) have been collected so far. 65.3% of patients presented ischemic (50%) and haemorrhagic (15.3%) stroke. A higher female predominance concomitantly with a similar age of onset and clinical features to what was reported in previous studies on Western patients has been confirmed. CONCLUSION An accurate and detailed clinical and neuroimaging classification represents the best strategy to provide the characterization of the disease phenotype and clinical course. The collection of a large number of biological samples will permit the identification of biological markers and genetic factors associated with the disease susceptibility in Italy.

Abstract
Moyamoya angiopathy (MA) is a cerebrovascular disease determining a progressive stenosis of the terminal part of the internal carotid arteries (ICAs) and their proximal branches and the compensatory development of abnormal “moyamoya” vessels. MA occurs as an isolated cerebral angiopathy (so-called moyamoya disease) or in association with various conditions (moyamoya syndromes) including several heritable conditions such as Down syndrome, neurofibromatosis type 1 and other genomic defects. Although the mechanism that links MA to these genetic syndromes is still unclear, it is believed that the involved genes may contribute to the disease susceptibility. Herein, we describe the case of a 43 years old woman with bilateral MA and peculiar facial characteristics, having a 484-kb microduplication of the chromosomal region 15q13.3 and a previously unreported 786 kb microdeletion in 18q21.32. This patient may have a newly-recognized genetic syndrome associated with MA. Although the relationship between these genetic variants and MA is unclear, our report would contribute to widening the genetic scenario of MA, in which not only genic mutation, but also genome unbalances are possible candidate susceptibility factors.

Abstract
BackgroundSacral dural arteriovenous fistulas (DAVFs) are rare vascular abnormalities of the spine characterised by slowly progressive symptoms that can mimic different myelopathy disorders.ObjectTo report our single Institution experience with sacral DAVFs.MethodsWe retrospectively reviewed the clinical records of patients admitted from 1 January 2006 to 31 December 2016 with a diagnosis of sacral DAVFs, treated by endovascular embolisation or surgical clipping. Clinical presentation, imaging characteristics, treatment results and follow-up were analysed.ResultsWe identify 13 patients with sacral DAVFs supplied by lateral sacral arteries. Clinical presentation was characterised by different degrees of motor weakness and sphincter disturbances. In all patients, spinal MRI showed spinal cord hyperintensities with enhancement and prominent perimedullary vessels. Selective internal iliac angiography was mandatory to identify the exact location of the fistula. A complete embolisation was achieved in eight patients performing a single endovascular embolisation and in three patients performing a single surgical disconnection: two patients required combined procedures. Follow-up imaging showed a complete resolution of the spinal cord hyperintensities in 81% of patients and a reduction of the intramedullary enhancement in 91%. Gait improvement was observed in 73% of patients, while remaining stable in 27%. Sphincter disturbances improved in 36% of patients and remained stable in 64%.ConclusionAwareness of sacral location of DAVFs is critical because standard spinal angiography will not identify sacral supplies, unless internal iliac arteries are properly examined. In our experience, the endovascular treatment show results comparable to surgery when the fistula point is correctly disconnected.

Abstract
OBJECTIVEThe objective of this study was to analyze the incidence of the primary complications related to positioning or surgery and their impact on neurological outcome in a consecutive series of patients undergoing elective surgery in the semisitting position.METHODSThe authors prospectively collected and retrospectively analyzed data from adult patients undergoing elective surgery in the semisitting position for a cranial disease. Patients were managed perioperatively according to a standard institutional protocol, a standardized stepwise positioning, and surgical maneuvers to decrease the risk of venous air embolism (VAE) and other complications. Intraoperative and postoperative complications were recorded. Neurointensive care unit (NICU) length of stay (LOS) and hospital LOS were the intermediate endpoints. Neurological outcome was the primary endpoint as determined by the modified Rankin scale (mRS) score at 6 months after surgery.RESULTSFour hundred twenty-five patients were included in the analysis. VAE occurred in 90 cases (21%) and it made no significant statistical difference in NICU LOS, hospital LOS, and neurological outcome. No complication was directly related to the semisitting position, although 46 patients (11%) experienced at least 1 surgery-related complication and NICU LOS and hospital LOS were significantly prolonged in this group. Neurological outcome was significantly worse for patients with complications (p < 0.0001).CONCLUSIONSEven in the presence of intraoperative VAE, the semisitting position was not related to an increased risk of postoperative deficits and can represent a safe additional option for the benefit of specific surgical and patient needs.

Abstract
BACKGROUND Tentorial dural arteriovenous fistulas (DAVFs) are uncommon, complex fistulas located between the leaves of the tentorium cerebelli with a specific anatomic and clinical presentation characterized by high hemorrhagic risk. We present a rare case of a medial tentorial DAVF successfully managed via transarterial embolization using SQUID liquid polymer. CASE DESCRIPTION A 60-year-old woman presented with a history of left progressive hearing loss and tinnitus for >1 year. Cerebral angiography demonstrated the presence of a medial tentorial DAVF with multiple arterial feeders, including the artery of Davidoff and Schechter; reverse venous outflow was observed in the inferior sagittal sinus and in multiple cortical veins. The patient underwent transarterial embolization with SQUID liquid polymer, an embolic agent that provides 2 different viscous formulations to cast the DAVF. The procedure went well without any complication, and the patient regained her preoperative status. In the postprocedural period, the patient experienced complete resolution of tinnitus. At 6 months, she remained asymptomatic, and cerebral angiography confirmed complete, stable occlusion of the fistula and normalization of cerebral deep venous outflow. CONCLUSIONS Medial tentorial DAVFs are considered the most complex DAVFs because of their location and extensive vascular supply. Our literature review focused on endovascular treatment of tentorial DAVFs to highlight the usefulness of new embolic agents in management of these diseases. To our knowledge, we report the first successful use of SQUID liquid polymer in management of a tentorial DAVF.

Abstract
The common m.3243A > G mutation of the mitochondrial DNA tRNALeu (UUR) gene is a maternally inherited mutation causing a wide spectrum of neurological and multisystemic disorders, including MELAS, characterized by recurrent cerebral infarction from young age. Vascular pathology in mitochondrial diseases has been described for small vessels, while large vessels involvement in mitochondrial diseases is considered rare. Here we report two female patients harboring the m.3243A > G mutation, in whom the diagnosis of mitochondrial disease was made after acute dissection of the internal carotid arteries. Our cases expand the clinical spectrum of this mutation, and support the idea of large vessels vasculopathy due to impaired mitochondrial function in the vessel wall that may lead to arterial wall weakness. Thus, stroke in mitochondrial diseases could also be related to large vessels disease, but further studies are strongly needed. Moreover, mitochondrial aetiology should be kept in mind in patients with large vessel dissection, especially in those with additional mitochondrial red flags.

Abstract
PURPOSE To compare the feasibility and safety of proximal cerebral protection to a distal filter during carotid artery stenting (CAS) via a transbrachial (TB) or transradial (TR) approach. METHODS Among 856 patients who underwent CAS between January 2007 and July 2015, 214 (25%) patients (mean age 72±8 years; 154 men) had the procedure via a TR (n=154) or TB (n=60) approach with either Mo.MA proximal protection (n=61) or distal filter protection (n=153). The Mo.MA group (mean age 73±7 years; 54 men) had significantly more men and more severe stenosis than the filter group (mean age 71±8 years; 100 men). Stent type and CAS technique were left to operator discretion. Heparin and a dedicated closure device or bivalirudin and manual compression were used in TR and TB accesses, respectively. Technical and procedure success, crossover to femoral artery, 30-day major adverse cardiovascular/cerebrovascular events (MACCE; death, all strokes, and myocardial infarction), vascular complications, and radiation exposure were compared between groups. RESULTS Crossover to a femoral approach was required in 1/61 (1.6%) Mo.MA patient vs 11/153 (7.1%) filter patients mainly due to technical difficulty in engaging the target vessel. Five Mo.MA patients developed acute intolerance to proximal occlusion; 4 were successfully shifted to filter protection. A TR patient was shifted to filter because the Mo.MA system was too short. CAS was technically successful in the remaining 55 (90%) Mo.MA patients and 142 (93%) filter patients. The MACCE rate was 0% in the Mo.MA patients and 2.8% in the filter group (p=0.18). Radiation exposure was similar between groups. Major vascular complications occurred in 1/61 (1.6%) and in 3/153 (1.96%) patients in the Mo.MA and filter groups (p=0.18), respectively, and were confined to the TB approach in the early part of the learning curve. Chronic radial artery occlusion was detected by Doppler ultrasound in 2/30 (6.6%) Mo.MA patients and in 4/124 (3.2%) filter patients by clinical assessment (p=0.25) at 8.1±7.5-month follow-up. CONCLUSION CAS with proximal protection via a TR or TB approach is a feasible, safe, and effective technique with a low rate of vascular complications.

Abstract
Taz is a signal-responsive transcriptional coregulator implicated in several biological functions, from chondrogenesis to regulation of organ size. Less well studied, however, is its role in thyroid formation. Here, we explored the in vivo effects on thyroid development of morpholino (MO)-mediated knockdown of wwtr1, the gene encoding zebrafish Taz. The wwtr1 gene is expressed in the thyroid primordium and pharyngeal tissue of developing zebrafish. Compared to mammalian cells, in which Taz promotes expression of thyroid transcription factors and thyroid differentiation genes, wwtr1 MO injection in zebrafish had little or no effect on the expression of thyroid transcription factors, and differentially altered the expression of thyroid differentiation genes. Analysis of wwtr1 morphants at later stages of development revealed that the number and the lumen of thyroid follicles, and the number of thyroid follicle cells, were significantly smaller. In addition, Taz-depleted larvae displayed patterning defects in ventral cranial vessels that correlate with lateral displacement of thyroid follicles. These findings indicate that the zebrafish Taz protein is needed for the normal differentiation of the thyroid and are the first to suggest that Taz confers growth advantage to the endocrine gland.

Abstract
The Fusaro Lagoon is a shallow lagoon, located in SW Italy, largely influenced in the last decades by several anthropic impacts. The study examined the pollution status of the lagoon, during year 2011-2012 at nine sampling stations with the aim to find out proper measurements of water lagoon restoration. Concentrations of heavy metals (HMs) (aluminium [Al], barium [Ba], cadmium [Cd], copper [Cu], iron [Fe], manganese [Mn], vanadium [V] and zinc [Zn]) were examined in water, sediments and specimens of the ascidian Ciona intestinalis sp. A. Low levels of dissolved oxygen concentration were detected at many stations, with mean values of 5.2-6.4 mg L(-1). The redox potential of surface waters was also low, -2.7 to 50.7 mV. Sediments possessed high organic matter content, 17.7-29.4%. In sediments, the mean Zn level, 251.4 mg kg(-1), was about sixfold higher than that recorded in year 2000 (38.5 mg kg(-1)) and considerably higher than that recorded in 2007 (191 mg kg(-1)). The mean levels of Cd were outstandingly high, with a mean value of 70.5 mg kg(-1), about 30- and 50-fold higher than those determined in 2000 and 2007, respectively. Cadmium (Cd), Cu and nickel (Ni) appeared in excess with respect to most current guidelines, reaching significant pollution levels. C. intestinalis sp. A was detected only at few stations, with metals accumulated preferentially in the body in respect to the tunic, from 1.2 times for Zn (178 mg kg(-1)) to 4.0 times for V (304 mg kg(-1)). Data suggests the necessity of an immediate action of eco-compatible interventions for environmental restoration.

Abstract
Assessment of cerebrovascular reactivity (CVR) is essential in cerebrovascular diseases, as exhausted CVR may enhance the risk of cerebral ischemic events. Transcranial Doppler (TCD) with a vasodilatory stimulus is currently used for CVR evaluation. Scanty data are available for Quantitative Magnetic Resonance Angiography (QMRA), which supplies higher spatial resolution and quantitative cerebral blood flow values. Aims of our pilot study were: (a) to assess safety and feasibility of CO2 administration during QMRA, (b) evaluation of CVR under QMRA compared to TCD, and (c) quantitative evaluation of blood flow from the major intracranial arterial vessels both at rest and after CO2. CVR during 5% CO2 air breathing was measured with TCD as a reference method and compared with QMRA. Fifteen healthy subjects (age 60.47 ± 2.24; male 11/15) were evaluated at rest and during CO2 challenge. Feasibility and safety of QMRA under CO2 were ensured in all subjects. CVR from middle cerebral artery territory was not statistically different between TCD and MRI (p>0.05). Mean arterial pressure (MAP) and heart rate (HR) increased during QMRA and TCD (MAP p=0.007 and p=0.001; HR p=0.043 and p=0.068, respectively). Blood flow values from all intracranial vessels increased after CO2 inhalation (p<0.001). CO2 administration during QMRA sessions is safe and feasible. Good correlation in terms of CVR was obtained comparing TCD and QMRA. Blood flow values significantly increased from all intracranial arterial vessels after CO2. Studies regarding CVR in physiopathological conditions might consider the utilization of QMRA both in routine clinical settings and in research projects.

Abstract
OBJECTIVES The goal of this study was to compare the rate of cerebral microembolization during carotid artery stenting (CAS) with proximal versus distal cerebral protection in patients with high-risk, lipid-rich plaque. BACKGROUND Cerebral protection with filters partially reduces the cerebral embolization rate during CAS. Proximal protection has been introduced to further decrease embolization risk. METHODS Fifty-three consecutive patients with carotid artery stenosis and lipid-rich plaque were randomized to undergo CAS with proximal protection (MO.MA system, n = 26) or distal protection with a filter (FilterWire EZ, n = 27). Microembolic signals (MES) were assessed by using transcranial Doppler during: 1) lesion wiring; 2) pre-dilation; 3) stent crossing; 4) stent deployment; 5) stent dilation; and 6) device retrieval/deflation. Diffusion-weighted magnetic resonance imaging was conducted before CAS, after 48 h, and after 30 days. RESULTS Patients in the MO.MA group had higher percentage diameter stenosis (89 ± 6% vs. 86 ± 5%, p = 0.027) and rate of ulcerated plaque (35% vs. 7.4%; p = 0.019). Compared with use of the FilterWire EZ, MO.MA significantly reduced mean MES counts (p < 0.0001) during lesion crossing (mean 18 [interquartile range (IQR): 11 to 30] vs. 2 [IQR: 0 to 4]), stent crossing (23 [IQR: 11 to 34] vs. 0 [IQR: 0 to 1]), stent deployment (30 [IQR: 9 to 35] vs. 0 [IQR: 0 to 1]), stent dilation (16 [IQR: 8 to 30] vs. 0 [IQR: 0 to 1]), and total MES (93 [IQR: 59 to 136] vs. 16 [IQR: 7 to 36]). The number of patients with MES was higher with the FilterWire EZ versus MO.MA in phases 3 to 5 (100% vs. 27%; p < 0.0001). By multivariate analysis, the type of brain protection was the only independent predictor of total MES number. No significant difference was found in the number of patients with new post-CAS embolic lesion in the MO.MA group (2 of 14, 14%) as compared with the FilterWire EZ group (9 of 21, 42.8%). CONCLUSIONS In patients with high-risk, lipid-rich plaque undergoing CAS, MO.MA led to significantly lower microembolization as assessed by using MES counts.

Abstract
Rotundone is an oxygenated sesquiterpene belonging to the family of guaianes, giving the 'peppery' aroma to white and black pepper and to red wines. Here we describe a novel, convenient protocol for the synthesis of rotundone, starting from a commercially available compound and requiring only two reaction steps, and an improved, faster method of GC separation (30 min) with selective quantisation of rotundone using tandem mass spectrometry in multiple reaction monitoring (MRM) mode with d(5)-rotundone as internal standard. With limits of detection (LODs) of 1.5 ng/L in white wine and 2.0 ng/L in red wine, intraday repeatability CV values of 6% and 5% at 50 ng/L and 500 ng/L and interday repeatability CV values of 13% and 6% at 50 ng/L and 500 ng/L, respectively, the improved protocol provides the desired sensitivity and selectivity for routine analysis of rotundone in both white and red wines. Initial application of this method highlighted the presence of unexpectedly high concentrations of rotundone, thus explaining the origin of the distinctive peppery aroma in Schioppettino and Vespolina red wines and in Gruener Veltliner white wines.

Abstract
OBJECTIVES To investigate the role of transcatheter closure of patent foramen ovale on the occurrence of migraine. BACKGROUND In recent years, a potential relationship between, migraine, stroke, and patent foramen ovale (PFO) has emerged. METHODS BioMedCentral, Google Scholar, and PubMed from January 2000 to December 2008 were systematically searched for pertinent clinical studies. Secondary sources were also used. Secondary prevention studies of transcatheter closure for patent foramen ovale were required to include at least more than 10 patients followed for more than 6 months. The primary end-point was the rate of cured or significantly improved migraine after percutaneous PFO closure. RESULTS After excluding 637 citations, we finally included a total of 11 studies for a total of 1,306 patients. Forty percent of the subjects included suffered from migraine, while most had a previous history of transient ischemic attack/stroke and were investigated retrospectively. Quantitative synthesis showed that complete cure of migraine in 46% (95% C.I.25-67%), while resolution or significant improvement of migraine occurred in 83% (95% C.I. 78-88%) of cases. CONCLUSIONS Notwithstanding the limitations inherent in the primary studies, this systematic review suggests that a significant group of subjects with migraine, in particular if treated after a neurological event, may benefit from percutaneous closure of their patent foramen ovale. However, many questions remain unsolved.
