    [Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

    Großes fronto-ethmoidales Osteom mit intraorbitaler und intrakranieller Ausbreitung

    Osteome sind die häufigsten gutartigen Tumore der Nasennebenhöhlen. In aller Regel sind sie asymptomatisch. Je nach Ausmaß und insbesondere bei intraorbitaler bzw. intrakranieller Ausdehnung können sie jedoch zu erheblichen Beschwerden führen.Es wird über einen 31 jährigen Patienten berichtet, bei dem seit elf Jahren ein ausgedehntes fronto-ethmoidales Osteom bekannt ist.Zum Zeitpunkt der Vorstellung beklagte der Patient einen progredienten Exophthalmus und gelegentlich auftretende frontale Cephalgien. Weitere Beschwerden bestanden nicht, insbesondere eine Sehminderung oder Doppelbilder wurden verneint.In der CT der Nasennebenhöhlen zeigte sich ein rechts betontes Osteom, das die Sinus frontales beidseits subtotal und große Teile beider vorderen Sinus ethmoidales ausfüllte. Der Tumor dehnte sich rechts nach intrakraniell und beidseits nach intraorbital aus. Rechtsseitig führt dies zu einer Verlagerung des Bulbus nach latero-kaudal mit direktem Kontakt zum N. Opticus.Nach interdisziplinärer Falldiskussion erfolgte aufgrund der zu erwartenden Begleitmorbitäten anstelle einer kompletten Exzision, die deutlich atraumatischere partielle Resektion mit Abtragung des symptomatisch gewordenen, intraorbitalen Anteils rechts über einen transfazialen Zugang nach Kilian.In der histologischen Aufarbeitung bestätigte sich die Diagnose eines Osteoms.Eine intraorbitale Ausdehnung von fronto-ethmoidalen Osteomen ist sehr selten. Durch Verlagerung des Bulbus und Opticuskompression können diese symptomatisch werden und sollten dann einer chirurgischen Therapie zugeführt werden.Der Erstautor gibt keinen Interessenkonflikt an
