Study Design: Prospective longitudinal study.
Objective: The serum titanium (Ti) concentrations were examined in patients implanted with a PRESTIGE LP Cervical Disc System (Medtronic, Inc., Memphis, TN). The metal-on-metal disc with ball-in-trough articulation is made of titanium alloy/titanium carbide composite (Ti-6Al-4 V/TiC).
Summary Of Background Data: Cervical disc arthroplasty provides a motion-preserving treatment alternative to anterior cervical discectomy and fusion for degenerative cervical disc disease. The articulating surfaces have a tendency to generate in vivo wear in the form of insoluble particulates (debris) and soluble metal ions. Not much information is available on the long-term metal concentrations observed in cervical disc arthroplasty and how these compare with the metal concentrations in Ti-based posterior fixation devices and other joint replacement implants.
Methods: Thirty patients were enrolled after strict exclusion criteria that included no previous permanent metal implants and no professional exposure to metal particles. High-resolution inductively coupled plasma-mass spectrometry was used to assay blood serum titanium concentrations preoperatively and at 3, 6, 12, 24, 36, 60, and 84 months after surgery. The detection limit for Ti was 0.2 ng/mL. The Friedman test was used to make longitudinal statistical comparisons.
Results: The median serum Ti concentrations determined preoperatively, and at 3, 6, 12, 24, 36, 60, and 84 months were 0.10, 1.22, 1.15, 1.27, 1.21, 1.46, 1.34, and 1.42 ng/mL, respectively. The serum Ti concentrations at all postoperative time points were significantly higher than that at the preoperative time point (Friedman P < 0.01).
Conclusion: The long-term postoperative serum Ti concentrations were significantly higher than the preoperative concentrations. The observed serum Ti concentrations in this study are lower than the reported concentrations in patients receiving posterior spinal instrumentation and metal or ceramic-on-polyethylene hip prostheses with Ti-alloy based stems and acetabular components.

Oncological Feasibility of Limited Neck Dissection in cN0 Supraglottic Laryngeal Cancer.
Head Neck
January 2025
Department of Medical and Surgical Sciences, Alma Mater Studiorum, University of Bologna, Bologna, Italy.
Background: Supraglottic squamous cell carcinoma (SCC) is a significant portion of head and neck cancers, with the management of clinically negative necks (cN0) through selective neck dissection (SND) being debated due to potential morbidities and low metastasis rates in levels IIb and IV.
Methods: This study is a retrospective, multicenter examination of the potential feasibility of limited neck dissection (LND), including only levels IIa and III in cN0 supraglottic SCC patients. It analyzed occult metastasis rates and explored relapse occurrences alongside potential predictors of lymph node metastasis.

Unit of Otorhinolaryngology-Head and Neck Department, ASST Sette Laghi, Varese and UPLOAD (Upper and Lower Airways Diseases) Research Centre, University of Insubria, Varese, Italy.
Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory condition characterized by persistent nasal obstruction, discharge, facial pressure, and olfactory dysfunction. CRSwNP significantly impairs quality of life (QoL), with olfactory loss being a particularly distressing symptom that affects food enjoyment, personal safety, and social interactions.
Methods: This study investigated the experiences of Italian patients with CRSwNP.
Prone Transpsoas Lumbar Interbody Fusion for Degenerative Disc Disease.
JBJS Essent Surg Tech
January 2025
Department of Neurosurgery, Center for Neuroscience and Spine, Virginia Mason Medical Center, Seattle, Washington.
Background: Prone transpsoas lumbar interbody fusion (PTP) is a newer technique to treat various spinal disc pathologies. PTP is a variation of lateral lumbar interbody fusion (LLIF) that is performed with the patient prone rather than in the lateral decubitus position. This approach offers similar benefits of lateral spinal surgery, which include less blood loss, shorter hospital stay, and quicker recovery compared with traditional open spine surgery.

Study Design/setting: A retrospective cohort study.
Objective: To compare long-term outcomes and complications of cervical disc replacement (CDR) and anterior cervical discectomy and fusion (ACDF) with cage-plate constructs (CPC) and stand-alone (SA) cages in treating degenerative cervical spondylosis.
Summary Of Background Data: ACDF is commonly used for cervical radiculopathy but may increase adjacent segment degeneration (ASD).

Background: Digestive system perforations after anterior cervical spine surgery (ACSS), if left untreated, are life-threatening. These injuries are often categorized as pharyngoesophageal. Although the pharynx and esophagus are continuations of each other, they are two distinct anatomical structures.
