Surgery for degenerative spinal pathologies in Parkinson's patients: low surgical benefits for high risks.

Purpose: Lumbar disc herniation, canal stenosis and cervicarthrosis are degenerative spinal pathologies frequently observed in the aging population of patients with Parkinson Disease (PD). Spinal surgery in PD patients remains risky with uncertain functional results. The main issue is to determine whether a surgical procedure should be performed on PD patients with common degenerative spinal pathologies (CDSP).

F-Naf PET/CT in pseudarthrosis after anterior cervical discectomy and fusion.

Background Context: Pseudarthrosis is a well-known cause of persistent or recurrent pain after anterior cervical discectomy and fusion (ACDF). Numerous radiographic criteria to determine the fusion status has been described in the literature, but their accuracies in clinical practice vary considerably and no 1 single method has proved superior. Fluorine-18 sodium fluoride (F-NaF) positron emission tomography/computed tomography (PET/CT), depicting osteoblastic activity, might be useful to identify pseudarthrosis after ACDF.

Risk of Infective Endocarditis in Patients with Spinal Surgical Site Infection and Bacteremia.

Surgical site infection (SSI) is responsible for significant morbidity, prolonged hospital stays, and increased costs. Infectious endocarditis (IE) is a rare but serious complication of bacteremia, particularly that resulting from SSI. The VIRSTA score predicts the risk of IE and determines the priority of transthoracic echocardiography (TTE) in patients with bacteremia.

Multicenter external validation of prediction models for clinical outcomes after spinal fusion for lumbar degenerative disease.

Background: Clinical prediction models (CPM), such as the SCOAP-CERTAIN tool, can be utilized to enhance decision-making for lumbar spinal fusion surgery by providing quantitative estimates of outcomes, aiding surgeons in assessing potential benefits and risks for each individual patient. External validation is crucial in CPM to assess generalizability beyond the initial dataset. This ensures performance in diverse populations, reliability and real-world applicability of the results.

A Staged Approach for Surgical Management of Basilar Invagination.

Background And Objectives: Patients with basilar invagination (BI) can be treated with several surgical options, ranging from simple posterior decompression to circumferential decompression and fusion. Here, we aimed at examining the indications and outcomes associated with these surgical strategies to devise a staged algorithm for managing BI.

Methods: We conducted a retrospective cohort study in 2 neurosurgical centers and included patients with a BI, as defined by a position of the dens tip at least 5 mm above the Chamberlain line.

Three-dimensional reconstruction of King Henri IV's paranasal sinuses and mastoid cells.

Purpose: The preserved head of King Henri IV of France (life 1553-1610, reign 1589-1610) has survived to the present day thanks to high-quality embalming and favorable conservation conditions. The aim of this study was to examine Henry IV's upper resonant cavities and mastoids using an original and innovative forensic three-dimensional segmentation method.

Methods: The paranasal sinuses and mastoid cells of King Henri IV of France were studied by cross-referencing available biographical information with clinical and flexible endoscopic examination and computed tomography (CT-scan) imaging.
