Show moreBackground The diagnostic accuracy of clinical probability assessment and D-dimer testing for clinically suspected recurrent deep vein thrombosis (DVT) is largely unknown. Aim To evaluate the safety of ruling out acute recurrent DVT based on an unlikely Wells score for DVT and a normal D-dimer test. Methods This was a predefined endpoint of the Theia study in which the diagnostic accuracy of magnetic resonance direct thrombus imaging in acute recurrent ipsilateral DVT was validated. The Wells rule and D-dimer test, performed as part of the study protocol, were not used for management decisions. The primary outcome of this analysis was the incidence of recurrent DVT at baseline or during 3-month follow-up for patients with an unlikely Wells score and a normal D-dimer test. Results Results of both Wells score and D-dimer tests were available in 231 patients without anticoagulant treatment. The recurrent DVT prevalence was 45% (103/231). Forty-nine patients had an unlikely Wells score and normal D-dimer test, of whom 3 (6.1%, 95% confidence interval [CI] 1.3%-18%) had recurrent DVT at baseline/follow-up, yielding a sensitivity of 97% (95% CI 92%-99%) and specificity of 36% (95% CI 28%-45%). Thus, if clinical probability scoring and D-dimer testing would have been applied, radiological imaging could have been omitted in 21% of patients with a diagnostic failure rate of 6.1%. Conclusion By applying clinical probability scoring and D-dimer testing, radiological imaging could be spared in one fifth of patients with suspected recurrent ipsilateral DVT. However, the high failure rate does not support implementation of this strategy in daily practice. Show less

Show moreBackground: Among chordoma patients, recurrent cases are by far more complex to be managed, and cranio-cervical junction (CCJ) localizations represent a particular challenge due to the complexity of the anatomical egion which makes it difficult to obtain a radical resection.Methodology: We report our personal experience in treating four patients with recurrent CCJ chordoma with "personalized" multiportal and eventually multistage approaches.Conclusions: Endoscopic endonasal approaches have gained widespread acceptance and are considered the workhorse in most cases of craniocervical junction chordomas. Nonetheless, in some cases of recurrence, or in presence of very lateralized lesions/ anatomical variations midline approaches are either contraindicated or very difficult to perform. In all these cases it seems reasonable to consider a versatile strategy including different approaches, modulating the surgical needs with different answers and solutions offered by the different routes. In other words to personalize as much as possible the approach, being creative and not dogmatic. Show less
