Training methods and analysis of races of a top level Paralympic swimming athlete

Training methods for Paralympic swimmers must take into account different pathologies, competitions classes, athlete\u2019s individual circumstances and peculiar physical adaptation mechanisms, hence general guidelines cannot be found in literature. In this study we present a training program, implemented for the physical preparation of a top level Paralympic swimmer. The athlete under study, affected by infantile cerebral palsy within a clinical picture of a spastic tetraparesis, by the end of 2016 was holder of Italian, European, world and Paralympic titles in the 400-m freestyle competition, S6 class. The training macrocycle was structured in a 3-fold periodization (three mesocycles), in view of the preparation to three international competitions. The 4-month training mesocycles prior to each competition differed substantially in terms of mileage load, intensity and recovery times. The first mesocycle was characterized by a sizeable low-intensity mileage load, the second one was shifted to lower mileage load, carried out at middle-to-high intensity levels, the third one entailed increased effort intensity, counterbalanced by lower mileage load. In all cases, recovery times were balanced to obtain optimized performance through physical adaptation to training stimuli, keeping into account the physiopatological response. Tapering phases were adjusted to maximize performance at competition. As an assessment of the effectiveness of the training method, correspondence between chronometric and technical parameters in the three competitions and the respective mesocycle training programs was found. The results of the present study may support the development of training guidelines for athletes affected by upper motor neuron lesions

The feasibility of three port endonasal, transorbital, and sublabial approach to the petroclival region: neurosurgical audit and multiportal anatomic quantitative investigation

Purpose: The petroclival region represents the "Achille's heel" for the neurosurgeons. Many ventral endoscopic routes to this region, mainly performed as isolated, have been described. The aim of the present study is to verify the feasibility of a modular, combined, multiportal approach to the petroclival region to overcome the limits of a single approach, in terms of exposure and working areas, brain retraction and manipulation of neurovascular structures. Methods: Four cadaver heads (8 sides) underwent endoscopic endonasal transclival, transorbital superior eyelid and contralateral sublabial transmaxillary-Caldwell-Luc approaches, to the petroclival region. CT scans were obtained before and after each approach to rigorously separate the contribution of each osteotomy and subsequentially to build a comprehensive 3D model of the progressively enlarged working area after each step. Results: The addition of the contralateral transmaxillary and transorbital corridors to the extended endoscopic endonasal transclival in a combined multiportal approach provides complementary paramedian trajectories to overcome the natural barrier represented by the parasellar and paraclival segments of the internal carotid artery, resulting in significantly greater area of exposure than a pure endonasal midline route (8,77 cm2 and 11,14 cm2 vs 4,68 cm2 and 5,83cm2, extradural and intradural, respectively). Conclusion: The use of different endoscopic "head-on" trajectories can be combined in a wider multiportal extended approach to improve the ventral route to the most inaccessible petroclival regions. Finally, by combining these approaches and reiterating the importance of multiportal strategy, we quantitatively demonstrate the possibility to reach "far away" paramedian petroclival targets while preserving the neurovascular structures

The “chameleon” sellar lesions: a case report of unexpected sellar lesions

IntroductionThe sellar region and its boundaries represent a challenging area, harboring a variety of tissues of different linings. Therefore, a variety of diseases can arise or involve in this area (i.e., neoplastic or not). A total of three challenging cases of “chameleon” sellar lesions treated via EEA were described, and the lesions mimicked radiological features of common sellar masses such as craniopharyngiomas and/or pituitary adenomas, and we also report a literature review of similar cases.MethodsA retrospective analysis of three primary cases was conducted at the Università degli Studi di Napoli Federico II, Naples, Italy. Clinical information, radiological examinations, and pathology reports were illustrated.ResultsA total of three cases of so-called “chameleon” sellar lesions comprising two men and one woman were reported. Based on the intraoperative finding and pathological examination, we noticed that case 1 had suprasellar glioblastoma, case 2 had a primary neuroendocrine tumor, and case 3 had cavernous malformation.ConclusionNeurosurgeons should consider “unexpected” lesions of the sellar/suprasellar region in the preoperative differential diagnosis. A multidisciplinary approach with the collaboration of neurosurgeons, neuroradiologists, and pathologists plays a fundamental role. The recognition of unusual sellar lesions can help surgeons with better preoperative planning; so an endoscopic endonasal approach may represent a valid surgical technique to obtain decompression of the optic apparatus and vascular structures and finally a pathological diagnosis

Extended endonasal approaches for pituitary adenomas

Pituitary adenomas presenting with significant extension beyond the sellar boundary, large size, asymmetrical shape and subarachnoid space invasion, although rare, represent a therapeutic challenge. The invasiveness of the tumor itself often limits the potential for complete tumor resection and increases the likelihood of intraoperative or postoperative complications, regardless of the approach. The extended endoscopic endonasal approach has been proposed as a valid alternative to the transcranial route for the treatment of certain pituitary adenomas not suitable to the standard transsphenoidal approach. Thanks to the wide and close up view provided by the endoscope via the appropriate expanded bone removal at the skull base, this technique offers, in an adequate working space, a safe exposure of the tumor and surrounding anatomical structures, at the supra-, para-, and retro-sellar areas. It stands clear that the primary goal of this approach remains the maximum allowed resection with preservation of neurological and endocrine functions. Herein, we debate the extended endoscopic endonasal technique for the treatment of pituitary adenomas, with the aim of underlying its indications, pitfalls, advantages, and limitations

The Effect of Kinesio Taping on Spasticity: A Randomized, Controlled, Double-Blind Pilot Study in Para-Swimmers

none7noCONTEXT: Kinesio Taping (KT) produces several clinical effects, including pain relief, edema absorption, and improved muscle performance. When applied in the insertion to origin mode, it is claimed to inhibit excessive muscle contractions.OBJECTIVE: Investigate whether KT applied in the insertion to origin mode could reduce the exaggerated reflex contraction of spastic muscles.DESIGN: Randomized crossover trial, with a restricted block randomization.SETTING: Clinical laboratory and swimming pool.PATIENTS: Seven para-swimmers.INTERVENTION: KT, applied in inhibitory mode, to investigate its effect on knee extensor spasticity.MAIN OUTCOME MEASURES: Primary outcome is stretch reflex, as compared with clinical assessment of spasticity by Modified Ashworth Scale and self-perceived spasticity by numeric rating scale. Secondary outcomes were Medical Research Council for strength of knee extensor muscles and chronometric swimming performance in 100-m freestyle.RESULTS: KT significantly decreased the amplitude of stretch reflex (P < .001), whereas the placebo treatment produced no significant effects. Scores of Medical Research Council for strength and Modified Ashworth Scale did not change after KT, whereas numeric rating scale scores for spasticity significantly decreased (P = .001). The swimming performance was significantly improved after KT treatment as compared with baseline (P < .01).CONCLUSIONS: This exploratory study performed on para-athletes suggests that KT could reduce spasticity. This outcome has 3-fold implications for clinical, rehabilitation, and sport methods.openPuce, Luca; Pallecchi, Ilaria; Marinelli, Lucio; May, Maria; Mori, Laura; Ruggeri, Piero; Bove, MarcoPuce, Luca; Pallecchi, Ilaria; Marinelli, Lucio; May, Maria; Mori, Laura; Ruggeri, Piero; Bove, Marc

Opioids prescriptions in pain therapy and risk of addiction: a one-year survey in Italy. Analysis of national opioids database

Objectives. Previous epidemiological studies reported a significantly higher risk of Amyotrophic Lateral Sclerosis (ALS) in Italian male soccer players. As a consequence, sports newspapers and news agencies focused on this issue and spread the news of 51 male soccer players with a reported diagnosis of ALS. Design. We searched news on male Italian national soccer players with a reported diagnosis of ALS quoted from January 1, 1950 to July 31, 2016 in at least two Internet web sites or in books by journalists. Results. A total of 39 male soccer players with a reported diagnosis of ALS were identified. Subjects were born from 1905 to 1973, 32 were currently deceased, 6 were still living, while the status of 1 player was unknown. All gathered information was available for 29 soccer players. The group had a mean age at diagnosis of 45.3 ± 12.2 years, a mean age at onset of symptoms of 46.4 ± 12.1 years, and a mean age at death of 50.9 ± 12.3 years. A significant inverse correlation between year of birth and age at onset of symptoms was observed, with a younger age at onset of symptoms in soccer players born in more recent years (r = -0.65, p < 0.01). Conclusions. Italian male soccer players with a reported diagnosis of ALS have a significantlyyounger age at diagnosis when compared to other European patients with ALS.Results support a possible relationship between soccer and the risk of ALS. We believethat further research is urgently needed in this field.

The gender impact in the era of COVID-19: an Italian neurosurgical perspective

Background: The aim of this study was to understand the impact of SARS-COVID-19 disease on neurosurgeons and our profession; specifically, to trace the role of women, in particular young neurosurgeons, in addressing this health emergency. Methods: This cross-sectional study evaluated the impact of SARS-COVID-19 disease on Italian neurosurgeons stratified by gender [44 (49.9%) males and 49 (52,1%) females] enrolled through a questionnaire-based online survey. Results: Ninety-three Italian neurosurgeons were included in this study. The percentage of female participants was 52,1%(49) and 53%(50) were younger than 40 years. Men were significantly more affected than women by complications (14 versus 3), while there was no gender difference in the Covid infection rate. Furthermore the social impact of the Pandemia was the same between men and women. Conclusions: Our analysis did not show significant differences between the two genders in the susceptibility, and mortality from COVID-19. The possible and immediate implementation of anti-COVID-19 measures and devices, associated with a lower risk of transmission in the treatment of neurosurgical pathologies, has likely, moderated and disregarded the socio-psychological "gender gap" of the Covid-19 pandemic

Surface Electromyography Spectral Parameters for the Study of Muscle Fatigue in Swimming

The purpose of this study was to assess validity, stability and sensitivity, of 4 spectral parameters\u2013median frequency (Fmed), mean frequency (Fmean), Dimitrov index (DI), and mean instant frequency (Fmi)\u2013in measuring localized muscle fatigue in swimming and to investigate their correlation with the variations of kinematic data and mechanical fatigue. Electrophysiological measures of muscle fatigue were obtained in real-time during a 100 m front crawl test at maximum speed in 15 experienced swimmers, using surface electromyography in six muscles employed in front crawl, while kinematic data of swimming was measured from video analysis. Mechanical fatigue was measured as the difference between muscle strength prior to and immediately after the 100 m front crawl in a dry-land multi-stage isometric contraction test. Statistically significant fatigue (p &lt; 0.0001) was found for all spectral parameters in all muscles. Fmed and Fmean varied between 10 and 25%, DI between 50 and 150%, and Fmi between 5 and 10%. Strong correlation (Pearson r 65 0.5) with mechanical fatigue was found for all spectral parameters except for Fmi and it was strongest for Fmed and Fmean. From our study, it turns out that Fmed and Fmean are more valid and stable parameters to measure fatigue in swimming, while DI is more sensitive

Management and treatment of brain tumors during pregnancy: an Italian survey

Purpose: The management of brain tumors during pregnancy is challenging. The clinical rarity and prognostic heterogeneity of such condition makes it difficult to develop standardized guidelines of treatment. The aim of this study was to assess the treatment options used in pregnant women with brain tumors that are currently used in Italy, considering the management of these patients reported in current literature in this field. Methods: A survey addressing the treatments options and management of brain tumors during pregnancy was designed on behalf of an ad-hoc task-force Neuro-Oncology committee of the Società Italiana di Neurochirurgia (SINch) to analyze the management of pregnant patients with brain tumors. We conducted a search of the literature published between January 2011 and September 2021, using MEDLINE (PubMed) in accordance to PRISMA guidelines. Data were discussed to obtain recommendations after evaluation of the selected articles and discussion among the experts. Results: A total of 18 Neurosurgical centers participated in the survey. A total of 31 pregnant women were included in this retrospective study. Meningiomas and gliomas were the two most common types of brain tumors diagnosed during pregnancy. An emergency surgical procedure was required in 12.9% of cases. Conclusion: A multidisciplinary and tailored approach is fundamental. In women showing clinical stability, neurosurgical options should preferably be delayed if possible, and considered during the second trimester or after delivery. In patients with acute neurological symptoms or tumor progression, medical abortion in the first trimester or a C-section in the second and third trimester need to be considered
