Despite the negative impact of cigarette smoking on oral health and teeth appearance, there is no data available on dental shade changes in smokers who quit smoking. Dental discoloration caused by smoking may be permanent, with minimal restoration after stopping smoking. If this is valid, former smokers can show dental shade values equivalent to those of current smokers.The aim of this study is to compare the dental shade assessment by digital spectrophotometry (VITA Easyshade V) in current, former and never smokers and to verify the short (7 days) and long-term (30 days) repeatability of these measurements.Confirmation of good reproducibility of VITA Easyshade V with clear objective discrimination of dental shade measurements among current, former, and never smokers will improve the power of this measurement giving more confidence in clinical research findings of dental shades in these populations.It is also anticipated that results from the study will expand the application of this measurements to include medical and regulatory research applied to combustion-free tobacco products (e.g. e-cigarettes, heated tobacco products, oral tobacco/nicotine products, etc.), smoking cessation medications, and to consumer care product for oral hygiene and dental aesthetics.

Although the detrimental health effects of smoking on human health are well described, the impact of smoking on dental plaque build-up lacks consistent records. This is because dental research on periodontal health has primarily relied on subjective indices with poor discriminatory power. Novel digital imaging techniques for the objective quantitation of dental plaque are now available. Quantitative Light-Induced Fluorescence (QLF) technology has been used in several studies for digital quantification and monitoring of dental plaque.The objective of the study is to quantitate and compare short- and long-term repeatability of dental plaque among current, former, and never smokers by using a high resolution, auto-focus, hand-held QLF scanner (QRayCam™ Pro; Inspektor Research Systems BV, Amsterdam, NL).Demonstration of good reproducibility of QLF technology with clear discrimination for dental plaque quantitation among current, former, and never smokers will pave the way to future application of this test for both medical and regulatory research applied not only to combustion-free tobacco products (e.g. e-cigarettes, heated tobacco products, oral tobacco/nicotine products, etc.) and smoking cessation medications, but also to consume care product for oral hygiene.

Tourette syndrome (TS) and obsessive–compulsive disorder (OCD) are two neurodevelopmental disorders characterized by repetitive behaviors. Our recent study in drug-naive children with TS and OCD provided evidence of cerebellar involvement in both disorders. In addition, cerebellar functional connectivity (FC) was similar in TS patients without comorbidities (TSpure) and TS patients with OCD comorbidity (TS + OCD), but differed in pure OCD patients. To investigate in detail the cerebellar involvement in the pathophysiology of TS and OCD, we explored cerebellar structural and functional abnormalities in drug-naive children with TSpure, TS + OCD, and OCD and assessed possible correlations with severity scores. We examined 53 drug-naive children, classified as TSpure (n = 16), TS + OCD (n = 14), OCD (n = 11), or controls (n = 12). All subjects underwent a multimodal 3T magnetic resonance imaging examination. Cerebellar lobular volumes and quantitative diffusion tensor imaging parameters of cerebellar peduncles were used as measures of structural integrity. The dentate nucleus was selected as a region of interest to examine cerebello-cerebral functional connectivity alterations. Structural analysis revealed that both TSpure and TS + OCD patients had higher fractional anisotropy in cerebellar peduncles than controls. Conversely, OCD patients were characterized by lower fractional anisotropy than both controls and TSpure and TS + OCD patients. Lastly, cerebellar functional connectivity analysis revealed significant alterations in the cerebello-thalamo-cortical circuit in TSpure, TS + OCD, and OCD patients. Early cerebellar structural and functional changes in drug-naive pediatric TSpure, TS + OCD, and OCD patients support a primary role of the cerebellum in the pathophysiology of these disorders.

Highlights • Feature Binding/integration in the motor domain in Tourette Syndrome (TS) is examined. • Motor binding processes and interleaved action are intact in TS. • Binding processes are differentially modulated in the motor domain and sensori-motor processes., Because tics are the defining clinical feature of Tourette syndrome, it is conceptualized predominantly as a motor disorder. There is some evidence though suggesting that the neural basis of Tourette syndrome is related to perception–action processing and binding between perception and action. However, binding processes have not been examined in the motor domain in these patients. If it is particularly perception–action binding but not binding processes within the motor system, this would further corroborate that Tourette syndrome it is not predominantly, or solely, a motor disorder. Here, we studied N = 22 Tourette patients and N = 24 healthy controls using an established action coding paradigm derived from the Theory of Event Coding framework and concomitant EEG-recording addressing binding between a planned but postponed, and an interleaved immediate reaction with different levels of overlap of action elements. Behavioral performance during interleaved action coding was normal in Tourette syndrome. Response locked lateralized readiness potentials reflecting processes related to motor execution were larger in Tourette syndrome, but only in simple conditions. However, pre-motor processes including response preparation and configuration reflected by stimulus-locked lateralized readiness potentials were normal. This was supported by a Bayesian data analysis providing evidence for the null hypothesis. The finding that processes integrating different action-related elements prior to motor execution are normal in Tourette syndrome suggests that Tourette it is not solely a motor disorder. Considering other recent evidence, the data show that changes in “binding” in Tourette syndrome are specific for perception–action integration but not for action coding.

Although the well-known detrimental effects of conventional cigarette smoking on oral health, there are still lack of evidences about the impact of less harmful alternatives (such as electronic cigarettes or heat not burn products), especially in young smokers with clinical absence of signs of periodontitis.SMILE will be a prospective, multicenter, interventional, open label, randomized, controlled, three parallel-arms study assessing oral health parameters and teeth appearance of 18 months duration.This study aims to compare short- and long-term impact on oral health between smokers continuing with conventional cigarette smoking, those switching to combustion-free nicotine delivery systems (C-F NDS), and never-smokers by objectively evaluating changes in gingival response, as a proxy for periodontal/gingival.The total number of participants in the study planned of the trial is 606 (505 regular smokers and 101 never-smokers).Regular smokers not intending to quit will be randomized in the ratio 1:4 either in continuing to smoke commercially manufactured conventional cigarettes (n = 101; Study Arm A) or switching to C-F NDS (n = 404; Study Arm B), never-smokers will be assigned in Arm C (n= 101).The primary outcome will be to assess and compare the percentage mean change in Modified Gingival Index (MGI) score between Baseline and 18 months follow-up between the Study Arms A and B.Secondary outcomes include the assessment of within- and between-group (Arm A, Arm B and Arm C) variations from baseline to 18 months follow-up of several endpoints, such as MGI, Tooth Stains Assessment, Dental Discolorations, Plaque Score Imaging, Oral Health Quality of Life (OHQOL) assessment and EuroQoL Visual Analog Scale (EQ VAS – QoL) assessment.Patient recruitment will start in January 2021 and enrolment is expected to be completed by June 2021.This will be the first study determining overall oral health impact of using CF-NDS in smokers without sign of periodontitis. Data from this study will provide valuable insights into the overall potential of C-F NDS to reduce the risk of periodontal diseases.

During the early stages of the coronavirus disease 2019 (COVID-19) pandemic in Italy, an online survey was launched via a local patient advocacy website to investigate mental health issues in children and adolescents with Tourette syndrome (TS). Respondents were parents, who were asked to report on their child's general health, tics, comorbidities/problems, pharmacological treatment/psychotherapy, symptom variations, and daily routine, as well as on their family's health and work experiences during the pandemic. Two hundred thirty-eight people participated in the survey, 203 females and 35 males. Our findings indicate that, in the time window of 4–6 weeks after the beginning of the COVID-19-related lockdown, 67% of individuals with TS developed a relevant worsening of the overall clinical condition as rated by their parents. An improvement or no variation of the clinical picture was reported in 20.5 and 6.7% of cases, respectively. Most worsened symptoms included tics, hyperactivity, rage attacks, obsessions/compulsions, and anxiety. Of the subjects experiencing a clinical worsening, the majority (51.76%) showed variations across two to five symptom domains. No association was found between symptom variation and family demographics or health and economic issues specifically related to the lockdown. The current COVID-19 pandemic is exerting a considerable impact on the mental health of young individuals with TS by worsening both tics and emotional and behavioral symptoms.

Tobacco smoking impairs mucociliary clearance (MCC) efficiency as shown by prolonged saccharin test transit time (STTT). Avoiding exposure to tobacco smoke from combustible cigarettes may restore MCC function and former smokers have been shown to exhibit similar STTT as never smokers. The impact of switching from smoking to combustion-free tobacco products such as e-cigarettes (ECs) and heated tobacco products (HTPs) on STTT is not known. We report STTT of exclusive EC and HTP users. Test results were compared to those obtained in current, former, and never smokers.STTT were obtained from 39 current, 40 former, 40 never smokers and from 20 EC and 20 HTP users. Comparison of STTT values showed significant difference among the five study groups (p< 0.00001) with current smokers having a median (IQR) STTT of 13.15 min, which was significantly longer compared to that of all other study groups. In particular, compared to former (7.26 min) and never smokers (7.24 min), exclusive EC users and exclusive HTP users had similar STTT at 7.00 and 8.00 min respectively.Ex-smokers who have switched to exclusive regular use of combustion-free nicotine delivery systems (i.e. ECs and HTPs) exhibit similar saccharin transit time as never and former smokers. This suggests that combustion-free nicotine delivery technologies are unlikely to have detrimental effects on MCC function.

Highlights • Intracranial hemorrhage occurs in COVID-19 patients with prolonged hospitalization. • SARS-CoV-2 binds to the endothelial lining of the cerebral vasculature via ACE-II. • Direct endothelial injury, pro-thrombotic states and DIC lead to hemorrhagic events. • We advocate heightened vigilance for intracerebral hemorrhage in COVID-19 patients., In this study, we report three cases of spontaneous intracranial hemorrhage in patients who were initially hospitalized at our tertiary care center in Washington, DC with symptoms of COVID-19. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was diagnosed in all three patients, who were critically ill, requiring intubation and ventilatory support. During their protracted hospitalizations, subsequent imaging disclosed intracranial hemorrhages, including intracerebral and subarachnoid hemorrhages, in the context of anticoagulation and coagulopathy. We believe this is related to the tropism of SARS-CoV-2 to the endothelial lining of the cerebral vasculature via their angiotensin-converting enzyme (ACE) II receptors. Given our findings, we advocate heightened vigilance for intracerebral hemorrhage events, and scanning when practicable, in COVID-19 patients which have prolonged ventilatory support and depressed neurologic examinations.

Previous studies in cohorts of Tourette syndrome (TS) or obsessive-compulsive disorder (OCD) patients have not clarified whether these two disorders represent two clinical conditions or they are distinct clinical phenotypes of a common disease spectrum. The study aimed to compare functional connectivity (FC) patterns in a pediatric drug-naive cohort of 16 TS patients without any comorbidity (TS), 14 TS patients with OCD (TS + OCD), and 10 pure OCD patients as well as 11 matched controls that underwent resting state fMRI. Via independent component analysis, we examined FC in the basal ganglia (BGN), sensorimotor (SMN), cerebellum (CBN), frontoparietal (FPN), default-mode (DMN), orbitofrontal (OBFN), and salience (SAN) networks among the above cohorts and their association with clinical measures. Compared to controls, TS and TS + OCD patients showed higher FC in the BGN, SMN, CBN and DMN and lower FC in the FPN and SAN. The TS and TS + OCD groups showed comparable FC in all networks. In contrast to controls, OCD patients exhibited increased FC in the BGN, SMN, CBN, DMN, FPN, and SAN. OCD patients also showed higher FC in CBN and FPN when compared with TS and TS + OCD patients both separately and as one group. Tic severity negatively correlated with FC in CBN and FPN in the TS group, while the compulsiveness scores positively correlated with the same two networks in OCD patients. Our findings suggest common FC changes in TS and TS + OCD patients. In contrast, OCD is characterized by a distinctive pattern of FC changes prominently involving the CBN and FPN.

When the standard arterial reconstruction is not feasible during liver transplantation (LT), aorto-hepatic arterial reconstruction (AHAR) can be the only solution to save the graft. AHAR can be performed on the infrarenal (IR) or supraceliac (SC) tract of the aorta, but the possible effect on outcome of selecting SC versus IR reconstruction is still unclear. One hundred and twenty consecutive patients who underwent liver transplantation with AHAR in six European centres between January 2003 and December 2018 were retrospectively analysed to ascertain whether the incidence of hepatic artery thrombosis (HAT) was influenced by the type of AHAR (IR-AHAR vs. SC-AHAR). In 56/120 (46.6%) cases, an IR anastomosis was performed, always using an interposition arterial conduit. In the other 64/120 (53.4%) cases, an SC anastomosis was performed; an arterial conduit was used in 45/64 (70.3%) cases. Incidence of early (

Tourette syndrome (TS) and chronic motor/vocal tic disorder (CTD) are neurodevelopmental conditions defined by the occurrence of multiple tics. Besides the well-known association with attention deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), rage attacks (RA) represent common and detrimental symptoms for patients. Inorder to explore prevalence of RA in tic disorders, relation to tic severity/comorbidities and available treatments, we performed a systematic literature review based on PRISMA Guidelines. 32 studies published between January 2008 – December 2019 were deemed suitable for the analysis and provided a prevalence of 20–67 %. Most findings showed a direct correlation with tic severity and a significant impact on psychosocial functioning. Although apparently related to comorbid ADHD, RA also frequently occur as independent manifestations. Association with other comorbidities, such as OCD, impulse control and mood disorders has also been reported, not yet fully established. Behavioral interventions appear to be effective, whereas there is limited evidence concerning the efficacy of medication. In TS/CTD, RA may be regarded as a major comorbidity that requires clinical investigation in order to develop personalized treatments.

To compare the percentage of voids in matched-taper single-cone fillings with GuttaFlow Bioseal or BioRoot RCS root canal sealers, using micro-computed tomography.Forty-eight single-rooted mandibular premolars were prepared using rotary files and randomly allocated into 2 groups (n = 24), wherein the canals were filled with a matched-taper single gutta-percha cone and one of the two sealers: Group 1, GuttaFlow Bioseal and Group 2, BioRoot RCS. The specimens were scanned with micro-CT before and after root canal filling. A specialized software was used to calculate the voids volume percentage (V%) in the filling for the whole root canal, root canal thirds, and the last millimeter from the apex. Data were statistically analyzed by ANOVA and Tukey tests (p 0.05).Root canals filled with GuttaFlow Bioseal had significantly less V% than those filled with BioRoot RCS in all the root-thirds (p 0.05) except at the apical 1 mm (p 0.05). Comparing the root-thirds, GuttaFlow Bioseal showed similar V% in all regions (p 0.05), while BioRoot RCS group had significantly greater V% in the coronal third compared with the other thirds (p 0.05).Root canals filled with a matched-taper single cone and GuttaFlow Bioseal had significant less voids than those with BioRoot RCS, except at the apical 1 mm.Voids in root fillings have been reported to have a negative impact on root canal treatment. This study highlights the percentage of voids in root fillings composed of a single cone of gutta-percha with two types of calcium silicate-based bioceramic sealers.

BACKGROUND: Sex-related differences in determinants of self-care in adults with type 1 diabetes mellitus (T1DM) were not investigated before. Knowing this could allow clinicians to better identify risk factors for inadequate self-care in male and female T1DM patients. The aim of this study was to assess sex-related differences in self-care behaviors and their determinants in adults with T1DM. METHODS: Secondary analysis from a multicenter cross-sectional study on a sample of 181 adults with T1DM. Clinical and socio-demographic data were collected by medical records. The Self-Care of Diabetes Inventory was used to measure self-care maintenance, self-care monitoring, self-care management and self-care confidence. Self-care confidence was scored also for its internal dimensions: task-specific self-care confidence and persistence self-care confidence. A standardized 0-100 score was used for each scale where a score

Introduction Stenotrophomonas maltophilia is a bacteria whose role in patients with cystic fibrosis (CF) bronchiectasis has been previously studied; little is known about its role in non-CF bronchiectasis. Materials and methods Aim of our study is to investigate the risk factors for S. maltophilia acquisition and its clinical impact on bronchiectasis patients. A retrospective observational cohort study enrolling patients attending the Bronchiectasis Clinic at the Royal Infirmary of Edinburgh, Scotland, UK. A total of 167 bronchiectasis patients undergoing intravenous (IV) antibiotic therapy were selected and divided according to single or chronic S. maltophilia isolation in sputum. The risk factors and prognostic impact were studied. Results Single isolation was independently associated with lower baseline % predicted forced expiratory volume in 1 s [odds ratio (OR) 0.98; 95% confidence interval (CI) 0.970–1.044; P = 0.025] and with less radiological involvement (OR 0.379; 95% CI 0.175–0.819; P = 0.01). Chronic isolation was associated with the number of IV antibiotic courses in the year before and after the first isolation (OR 1.2; 95% CI 1.053–1.398; P = 0.007) and with the absence of Pseudomonas aeruginosa colonization (OR 0.207; 95% CI 0.056–0.764; P = 0.02). In the chronic isolation group, there were more exacerbations and more need of IV antibiotics in the year after the first isolation. Conclusions Poor lung function is the main independent risk factor for single isolation of S. maltophilia. For chronic colonization, the main independent risk factor is the number of IV antibiotic courses and the absence of P. aeruginosa chronic colonization. Only when chronically present, S. maltophilia had a clinical impact with more exacerbations.

In today’s medical landscape, surgeons must be adept in the indications and techniques for revision surgery in the previously reconstructed cervical spine to achieve successful outcomes for their patients

A spine surgeon must contemplate multiple factors, including a patient’s overall health and functional status, pathology, surgical goals, levels involved, and one’s own comfort level before undertaking a thoracic corpectomy. A variety of approaches have been developed over the last several decades to maximize access to and minimize manipulation of the thoracic spinal cord.

A NaX nanozeolite-geopolymer monolith, with hierarchical porosity, has been produced by a one-pot hydrothermal synthesis using metakaolin as alluminosilicate source and a sodium silicate solution as activator. Its final composition, reported in terms of oxides, is 1.3-Na₂O-3.0SiO₂-1Al₂O₃-12H₂O. Its microstructural and chemical features and CO₂ adsorption performance have been investigated. The microstructure of the composite is characterized by NaX zeolite nanocrystals glued by the geopolymeric binder to form a complex three-dimensional network of pores. Overall porosity resulted ~23.5%, whereas compressive strength is 16±0.7 MPa. Monolith showed BET surface area of 350 m²/g, a micropore surface area of 280 m²/g and a mesopore volume, due to the geopolymeric binder, of 0.09 cm³/g. Its CO₂ adsorption capacity has been measured at the temperatures of 7, 25 and 42 °C up to 15 bar using an optimized Sievert-type (volumetric) apparatus. All the adsorption data were evaluated by Toth/Langmuir isotherm model and commercial pure NaX zeolite was used as reference. CO₂ adsorption isotherms show a maximum uptake value around 21 wt% at (~7 °C) that decrease to 18 wt% at high temperature (~42 °C) passing through 19 wt% at room temperature (~25 °C). The homogeneity grade of the surface, as obtained using Toth analysis performed on the adsorption isotherm, is close to

Micro-Raman spectroscopy has been used to monitor structural defects and stress state developing in diamond due to formation of 3D graphitic electrodes for the achievement of optimized carrier collection in ionizing radiation and particle diamond detectors. Buried graphitic pillars were fabricated in a single-crystal CVD-diamond sample by means of a 400 fs pulsed laser operating at λ = 1030 nm. The same conditions were also used for the realization of two series of graphitic strips on the surface allowing buried pillars connections. Micro-Raman spectra of untreated regions exhibit the typical diamond peak at 1332 cm−1 which largely changes within the laser modified regions, where a G band in the range 1580–1600 cm−1 is also detected. Strength decrease, shifting and broadening of the diamond Raman peak are observed by crossing graphitic electrodes and along buried pillars, pointing out that phase transition from diamond to graphitic carbon is accompanied both by stress development and structural disorder in the residual diamond tissue. In these regions, Raman spectra also exhibit a broad photoluminescence background signal, whose intensity appears related to graphitization process. In particular, a splitting of the diamond Raman peak is detected around pillars on the top surfaces suggesting the occurrence of a laser-induced biaxial stress. From these results it is then tentatively suggested that conduction in the realized electrodes occurs through both conductive graphitic phases and disordered diamond paths, whereas detector performance is mainly related to charge transport within virgin diamond.

Underwater divers face several potential neurological hazards when breathing compressed gas mixtures including nitrogen narcosis which can impact diver's safety. Various human studies have clearly demonstrated brain impairment due to nitrogen narcosis in divers at 4 ATA using critical flicker fusion frequency (CFFF) as a cortical performance indicator. However, recently some authors have proposed a probable adaptive phenomenon during repetitive exposure to high nitrogen pressure in rats, where they found a reversal effect on dopamine release., info:eu-repo/semantics/published

To investigate the retreatability of two calcium silicate-based materials (BioRoot RCS, Septodont, Saint-Maur-des-Fossés, France and GuttaFlow Bioseal, Colténe/Whaledent AG, Langenau, Germany) using rotary instrumentation combined with supplementary irrigant agitation techniques using extracted teeth in a laboratory setting.The root canals of extracted single-rooted mandibular premolars were prepared to size 40, .04 taper and randomly divided into two experimental groups (n = 36) depending on the root filling material. Root canals were filled with gutta-percha and GuttaFlow Bioseal (GB, group 1) or BioRoot RCS (BR, group 2), scanned using a micro-CT scanner and stored in phosphate-buffered saline for 4 months. Removal of root filling was performed with rotary instruments, and specimens were randomly allocated to one of the subgroups for supplementary irrigant agitation (n = 12): subgroup A, syringe irrigation (control); subgroup B, Tornado Brush (M.I.B, Suresnes, France) and subgroup C, ultrasonically activated irrigation. Specimens were re-scanned with micro-CT to calculate the volume of remnant root filling material. Data were analysed statistically by two-way ANOVA and post hoc Tukey's tests (P = 0.05).Specimens filled with GuttaFlow Bioseal were associated with a significantly smaller volume of root filling remnants compared with BioRoot RCS (P 0.05). There was no significant difference between the supplementary irrigant agitation subgroups in the removal of GB (P 0.05). In group 2 (BioRoot RCS), subgroups B (Tornado Brush) and C (ultrasonically activated irrigation) were associated with a significantly smaller volume of root filling remnants compared with subgroup A (syringe irrigation) (P 0.05). There was no significant difference between subgroups B and C (P 0.05).Significantly smaller volumes of root filling remnants of GuttaFlow Bioseal, than BioRoot RCS, were present after their removal with rotary instruments and irrigation. Supplementary irrigant agitation techniques were associated with smaller volumes of remnants during the removal of BioRoot RCS but not that of GuttaFlow Bioseal.

Background Spondylolysis is a defect in the pars interarticularis that typically presents with axial back pain. Recently, minimally invasive spine techniques have increased in popularity and have been applied to the Buck technique of direct pars repair. Case Description In our series, 2 patients underwent minimally invasive direct pars repair by the percutaneous insertion of a cannulated lag screw across the pars defect with compression against the lamina. The defect was then decorticated and packed with bone grafting material through a tubular retractor. The clinical records, including preoperative imaging characteristics and intraoperative variables, were collected. The first patient was a 22-year-old woman with bilateral pars defects, and the second was a 21-year-old woman with a left-sided pars defect. They underwent minimally invasive direct pars repair without complications and were discharged home within 24–48 hours. In the first patient, the fusion was successful; however, the second experienced screw back out and required subsequent revision. The follow-up period was 25 months for patient 1 and 21 months for patient 2. The fracture morphology differed. The successfully repaired fractures were linear with smooth cortical edges and oriented perpendicular to the screw trajectory. The failed repair involved a unilateral, curved defect with comminuted cortical edges. Conclusion Minimally invasive direct pars repair can be performed safely and effectively with shortened hospital stays and reduced morbidity. Fracture morphology and orientation could be important predictors of the success of surgery.

Objective Misophonia is a condition characterized by the dislike or hatred (miso) of specific sounds (phonia) that results in an extreme emotional response. There has been growing interest in misophonia, with emerging evidence from neurodevelopmental populations and ongoing debate regarding the psychiatric classification and the mechanisms underlying this phenomenon. This is the first article to report on misophonic experiences and associated clinical characteristics in young people with tic disorders. Method In this article, we present the cases of 12 children and young people with tic disorders who have attended clinics in the United Kingdom and Italy who report misophonia. Misophonia was classified as a selective aversive response in accordance with the criteria proposed by Schroder. Results These cases support the view that a range of auditory stimuli may lead to negative/aversive emotional responses of varying degrees, with misophonia seeming to contribute to behavioral reactions. Among these, the most frequent was anger outbursts, followed by an increase in tics, trigger avoidance, repetition of the sound, and self-injurious behavior. No single treatment approach was effective, with some patients responding to cognitive behavioral therapies and others to pharmacological support. Conclusion We postulate that misophonia could be an underestimated causative phenomenon for abrupt emotional dysregulation in individuals with tic disorders and should be considered as part of a comprehensive clinical assessment. This article presents findings of relevance to general discussions regarding the classification of misophonia, as well as the potential relationship between sensory abnormalities and the broader phenotype of tic disorders during development.

A detailed characterization under 90Sr β-particles and 4.5 MeV protons micro-beam of a single-crystal CVD diamond-based three-dimensional detector with surface and buried graphite electrodes is presented. Pillar contacts, 300 µm long and 30 µm diameter, were fabricated by using a femtosecond laser operating at 1030 nm wavelength and 400 fs pulse duration. Charge collected under 90Sr β-particles was measured in front and back irradiation conditions, pointing out that the pillars contribute to the charge collection. Charge collection efficiency (CCE) was measured to be up to 94% under proton beam irradiation. Results of a comprehensive study, including crossed-polarizers imaging, numerical simulation of the electric field distribution, and proton mapping, show that CCE is not affected from the stress induced by the pillar fabrication, and that the electric field strength is high enough to partially compensate for carrier recombination in the defected regions surrounding the pillars.

In the last decades there has been an increase in the rate of high-energy traumas. They lead to multiple traumatic injuries, affecting different organs and body systems. The approach to these multi-trauma patients is complex and requires the cooperation of a multi-disciplinary team of experts working together. Orthopaedic treatment is generally considered after vital parameters have been stabilized, but should not be excessively postponed to avoid complications at the time of surgery. Upper limb injuries are frequent but often misdiagnosed and not adequately treated. The authors describe the current treatment of the most frequent injuries of shoulder, elbow, wrist and hand in polytrauma patients.

Resumen Introduccion y objetivos Se sabe poco sobre los riesgos y los resultados del embarazo en mujeres con sindrome de Brugada. Por lo tanto, se evalua la influencia del embarazo en pacientes con sindrome de Brugada. Metodos Se realizo un analisis retrospectivo de todas las embarazadas con sindrome de Brugada. Se incluyo a 104 mujeres con un total de 219 partos. Resultados Hubo 15 abortos espontaneos; 1 nino fallecio subitamente durante la noche 3 meses despues del nacimiento; 6 embarazadas refirieron haber sufrido al menos un sincope durante el embarazo; en ninguna de las 3 mujeres a las que se implanto un desfibrilador automatico implantable antes del embarazo se registraron episodios arritmicos; 4 pacientes con antecedente de muerte subita cardiaca recuperada no sufrieron evento alguno durante el embarazo. De las 24 pacientes que habian sufrido sincopes cuando no estaban embarazadas, 18 se mantuvieron asintomaticas y 6 sufrieron sincope durante el embarazo. Durante el seguimiento (media, 298,9 dias; intervalo de confianza del 95%, 289,6-308,2) 2 mujeres recibieron descargas apropiadas. Conclusiones En este estudio unicentrico y retrospectivo, los eventos graves no fueron mas frecuentes durante el embarazo y el periodo periparto en las mujeres con sindrome de Brugada. La aparicion de sincopes durante el embarazo no se asocio a una peor evolucion en los periodos periparto y posparto ni durante el seguimiento. La tasa descrita de abortos espontaneos y muerte subita infantil debera investigarse en nuevos estudios para confirmar o descartar su asociacion con el sindrome de Brugada.

We introduce the electrical characterization of 2.5 mm-long graphite pillars buried in single crystal CVD diamond. A mode-locked Ti:Sapphire laser generating 5 ps pulses at the wavelength of 800 nm with a repetition rate of 1 kHz has been used to directly produce graphite columns with a diameter of about 10 m and an aspect ratio greater than 240. A pair of 12 pillars was realized within the diamond bulk starting from opposite lateral faces resulting in an interdigitated-like structure buried within the diamond volume. Tests with 2.28 MeV electrons emitted by 90Sr,Y collimated radioactive source demonstrate that the charge collected by the active volume saturates at 1.00±0.02 fC at an electric field strength evaluated as ±1.3 V/m with electrons impinging parallel to the rows. The collected charge, much lower than that expected by theoretical estimation, has been tentatively attributed to a loss of biasing due to the probable non-continuity of the graphite pillars within the sample.
