Fistole rinoliquorali spontanee: verso un moderno algoritmo diagnostico-terapeutico.

Introduzione: Le fistole rinoliquorali spontanee sono un eterogeneo gruppo di fistole a cui afferiscono tutti i casi di fistola rinoliquorale per le quali non \ue8 stata possibile identificare un meccanismo eziopatogenetico. Permane tuttavia il dubbio da parte di molti autori che in tale gruppo confluiscano fistole rinoliquorali causate da patologie non correttamente diagnosticate. Sebbene siano state effettuate numerose ricerche per meglio identificare l\u2019eziologia e la patogenesi delle fistole rinoliquorali spontanee non si \ue8 ancora giunti a formulare un algoritmo diagnostico-terapeutico condiviso. Tale tipologia di fistole, dai dati ricavati dalla analisi della letteratura, \ue8 gravata da un maggiore tasso di recidiva rispetto alle fistole a eziologia nota probabilmente proprio poiche' il fattore eziopatogenetico rimane spesso misconosciuto e conseguentemente non trattato. Materiali e Metodi: Il presente studio, attraverso una valutazione retrospettiva della casistica (2002-2013) delle Cliniche Otorinolaringoiatrica e Neurochirurgica dell\u2019Ospedale del Circolo e Fondazione Macchi-Universit\ue0 degli Studi dell\u2019Insubria di Varese, analizza una popolazione di 103 pazienti sottoposti a intervento chirurgico di riparazione di fistola rinoliquorale spontanea.

Epidemiology-based evaluation of trends in treatment for ruptured intracranial aneurysms in Italy

Background: In recent years there have been significant advances in the diagnosis, management and treatment of intracranial aneurysms (IAs) in Italy. Changes in prevalence of several epigenetic risk factors in the population as well as in environmental factors may have influenced the epidemiological burden of this disease. No long-term, population-based study about the incidence of treated ruptured IAs (rIAs) in Italy has yet been reported in literature. Methods: A long-term (January 2015 - December 2020), nationwide epidemiology study was performed by using discharge data collected by the Italian National Agency for Regional Healthcare Services with a particular focus on the treatment incidence of rIAs. A sub-analysis per macro-areas (north, center, and south and islands) was also performed, including the data about regional healthcare systems organization. The prevalence of common epigenetic and environmental risk factors has been also assessed. Results: Over 6 years, the mean incidence of rIAs treatment was 2.7 x 100.000 per year (ds ± 0.1; range: 2.6-2.9). In 2020, there was a significant north-south decreasing gradient in incidence (north vs center vs south and islands: 3.4 vs 2.4 vs 1.8 x 100.000/year; all p<0.001). There were no meaningful differences between macro-areas in terms of access to emergency care and number of neurosurgical wards per population. The rate of unruptured IAs (uIAs) treatment did not show a correlation to that of ruptured ones. Minor regional differences were retrieved for high-risk hypertension as well as for alcohol abuse prevalence. Air pollutants and temperature charts showed a north-south gradient similar to that of the incidence in the treated rIAs. Conclusions: The mean incidence of treated rIAs was stable over the 2015-2020 period in Italy. A north-south decreasing gradient in rIAs treatment incidence was reported. Neither the Regional healthcare organizations nor the rate of uIAs treatment were significant factors explaining the regional differences in the incidence of rIAs treatment. Minor differences in epigenetic and environmental risk factors may be synergistically involved

ACTH-dependent Cushing's Syndrome: Diagnostic Pitfalls in Concomitant Non-secreting Pituitary Adenomas

Objectives: To describe the possible pitfalls in correctly interpreting clinical, radiological and biochemical findings in ACTH-dependent Cushing's syndrome. Methods: We describe a case of a pituitary adenoma visualized at MRI not correlated with an ACTH-dependent Cushing’s syndrome. Results: Radiological imaging and hormonal testing can be misleading in suspected pituitary ACTH-related Cushing’s syndrome. Conclusion: Correct interpretation of the initial clinical presentation can help in the proper diagnosis and treatment of ACTH-dependent Cushing’s syndrome

Unequal impact of COVID-19 on private and academic neurosurgical workforce: results of an international survey

Background: Since the COVID-19 outbreak several manuscripts regarding neurosurgical practice during this pandemic have been published. Qualitative studies on how the pandemic affected neurosurgeons, with additional focus on their practice, are still scarce. This study's objective was to investigate the impact of COVID-19 on various aspects of the professional and private life of a homogeneous group of international neurosurgeons affiliated to the European Association of Neurosurgical Societies (EANS).Methods: Neurosurgeons from Europe and abroad were invited to participate in an online survey endorsed by the Individual Membership Committee of the EANS. The survey captured a subjective snapshot of the impact of the first wave of the COVID-19 pandemic on EANS members and was advertised through its Institutional website. In addition to departmental data, personal feeling of safety, financial security, local precautions, number of surgeries performed, changes in daily routine, and other practice-related information were inquired. Differences among practice types were closely reviewed.Results: The survey was distributed between April and May 2020: 204 neurosurgeons participated. Participants were typically active EANS members (73%), consultants (57.9%), from university hospitals (64.5%). Elective surgical practice was still ongoing only for 15% of responders, whereas 18.7% of them had already transitioned to COVID-19 and emergency medical services. While 65.7% of participants thought their institutions were adequately prepared, lack of testing for SARS-CoV-2, and scarcity of personal protective equipment were still a matter of concern for most of them. Overall surgical activity dropped by 68% (cranial by 54%, spine by 71%), and even emergencies decreased by 35%. COVID-19 prompted changes in communication in 74% of departments, 44% increased telemedicine by >50%. While most neurosurgeons had concerns about personal and families' health, financial outlook appeared to be gloomy only for private practitioners.Conclusion: The lockdown imposed in many countries by the COVID-19 outbreak called for immediate modification of working routine and resulted in a dramatic decrease of elective surgical procedures. Neurosurgeons share common concerns but were not equally exposed to the personal health and financial dangers of the ongoing pandemic.Scientific Assessment and Innovation in Neurosurgical Treatment Strategie

Identifying developmental coordination disorder: MOQ-T validity as a fast screening instrument based on teachers' ratings and its relationship with praxic and visuospatial working memory deficits.

The present study was devoted to test the validity of the Italian adaptation of the Motor Observation Questionnaire for Teachers (MOQ-T, Schoemaker, Flapper, Reinders-Messelink, & De Kloet, 2008) as a fast screening instrument, based on teachers' ratings, for detecting developmental coordination disorders symptoms and to study its relationship with praxic and visuospatial working memory deficits. In a first study on a large sample of children, we assessed the reliability and structure of the Italian adaptation of the MOQ-T. Results showed a good reliability of the questionnaire and a hierarchical structure with two first-order factors (reflecting motor and handwriting skills), which are influenced by a second-order factor (general motor function) at the top. In a second study, we looked at the external validity of the MOQ-T and found that children with symptoms of Developmental Coordination Disorder (children with high scores on the MOQ-T) also had difficulty reproducing gestures, either imitating others or in response to verbal prompts. Our results also showed that children with high MOQ-T scores had visuospatial WM impairments. The theoretical and clinical implications of these findings are discussed

How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p &lt; 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p &lt; 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p &lt; 0.0001) or urgent (20.4% vs. 38.5%; p &lt; 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p &lt; 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

Outcome of elderly patients undergoing intracranial meningioma resection: a single center experience

Higher life expectancy and higher mean age in general population created growing interest in medical and surgical management of meningiomas in elderly. It is well known that, due to possible complications, pre-operative status and comorbidities, expecially in aged people, should be carefully considerated in the decision-making process. We described our experience with this kind of patients and analized the influence of complications on the outcome
