Tips and tricks of cement removal in the case of revision surgery
No full textZusammenfassung Hintergrund Aktuelle Re-Revisionsraten nach endoprothetischem Gelenkersatz liegen in Deutschland bei 28–37 %. Insbesondere verbliebende Zementreste sind für erneute Revisionseingriffen nach Sanierungsoperationen bei periprothetischen Infektionen ursächlich, weswegen die vollständige Zemententfernung von großer Bedeutung ist. Die Entfernung letzter Zementreste stellt den Operateur jedoch häufig vor technische Herausforderungen. Eine komplikationslose und vollständige Zemententfernung bedarf einer umfangreichen präoperativen Vorbereitung, um die bestmögliche Operationsstrategie zu entwickeln. Therapie Von verschiedenen Herstellern werden Spezialinstrumente angeboten, die die Zemententfernung im Revisionsfall erleichtern. Neben endoluminalen Zugängen existieren Zugangserweiterungen wie zusätzliche Osteotomien, welche die vollständige Zemententfernung erleichtern. Nicht zuletzt sollte der Operateur in der Lage sein, nach einem definierten Zeitintervall die Indikation zum intraoperativen Vorgehenswechsel zu stellen.Abstract Background In Germany, current revision rates after arthroplasty range between 28–37%. In particular, remaining cement residues are causative for additional revision surgery after periprosthetic joint infection, which is why complete cement removal is of high importance. However, the removal of remaining cement residues often confronts the surgeon with technical challenges. Complication-free and complete cement removal requires extensive preoperative preparation in order to develop the best possible surgical strategy. Treatment Special instrument sets to facilitate cement removal in revision cases are available from various manufacturers. In addition to endoluminal approaches, access enhancements such as extended osteotomies exist to facilitate complete cement removal. Finally, the surgeon should be able to give the indication for an intraoperative procedural change after a defined time interval

Correction: Interleukin-6 as a critical inflammatory marker for early diagnosis of surgical site infection after spine surgery

No full textAbstract Purpose Early diagnosis of surgical site infections (SSIs) could prevent surgical revision. Inflammatory markers (IMs), such as procalcitonin (PCT), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α), seem more accurate in diagnosing SSI than C-reactive protein (CRP) and white blood cell (WBC) count. The aim was to compare the predictive values of CRP, WBC count, PCT, IL-6, and TNF-α in SSI detection. Methods A total of 130 patients undergoing dorsal spondylodesis from 2019 to 2024 were enrolled in a prospective diagnostic study at a maximum care spine center. IMs were measured preoperatively and on the postoperative days (PODs) 1, 2, 3, 5, and 7. Patients with high suspicion of SSI underwent revision surgery. SSI was diagnosed when the microbiological evidence was positive. Patients were divided a posteriori into the non-infection and infection groups. Results IMs of 118 patients (66.9 ± 13.0 years, 61.0% females) were measured. Fifteen of the 118 patients (12.7%) developed an SSI. The groups differed with respect to existing hypertension, number of instrumented segments, region of surgery, CRP POD1,7 , PCT POD7 , and IL-6 POD3,5,7 . Binary logistic regression for SSI detection including these parameters showed an area under the curve (AUC) of 0.88 (95% CI 0.79–0.98; P < 0.001). The main effect for SSI detection was maintained by IL-6 POD7 (odds ratio = 1.13; 95% CI 1.05–1.23; P = 0 . 001), which itself showed an AUC of 0.86 (95% CI 0.75–0.97). Conclusion Compared to CRP, WBC count, PCT, and TNF-α, IL-6 seems to be the critical IM for the early detection of an SSI.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
