Introduction: Proximal humeral fracture is a common cause of morbidity in the elderly and poses a challenge for the orthopedic surgeon. Open reduction and internal fixation (ORIF) with a locking plate is associated with high rate of secondary implant-related complications (IRC). Early implant removal could potentially reduce the risk of IRC and further improve the outcome in relatively asymptomatic patients. The purpose of this study was to evaluate the clinical and radiologic outcomes following implant removal.
Methods: A total of 56 patients with an average age of 63 ± 13 years and a mean follow-up of 29 months were evaluated retrospectively following removal of a locking plate in the proximal humerus. Postoperative functional outcomes were evaluated with the Constant-Score, Subjective shoulder value and DASH score.
Results: Early implant removal resulted in high functional outcomes with 96% of the patients reporting an improvement of their shoulder function following implant removal. No intraoperative complications were reported. Avascular necrosis (AVN) of the humeral head occurred in 12.5% of the patients, but no secondary screw cut-out was reported.
Conclusion: Early implant removal might be a safe option to avoid secondary IRC with significant subjective functional improvement also in asymptomatic patients. Although early implant removal cannot reverse the process of AVN, it could potentially prevent secondary IRC and subsequent glenohumeral cartilage destruction.

Low-profile double plating versus conventional single plating in midshaft clavicle fractures: A retrospective study and initial experience with this novel technique.
PLoS One
January 2025
Department of Orthopedic and Trauma Surgery, Lucerne Cantonal Hospital, Lucerne, Switzerland.
Background: Low-profile double plating seems a viable alternative to conventional single plating for fixation of midshaft clavicle fractures. This study aims to compare the two techniques regarding healing, complications, and removal rate.
Methods: This retrospective cohort study included all patients >16 years that underwent plate fixation for midshaft clavicle fractures between 2020 and 2022 at one trauma-center.

Department of Oral Health, Faculty of Oral Health Science, Kristianstad University, 291 88, Kristianstad, Sweden.
Purpose: The study assessed the clinical outcomes following treatment of peri-implant mucositis using Er:YAG laser or an ultrasonic device over six months. Patients' experience of pain, aesthetics, and Quality of life were further assessed.
Methods: One dental implant, per included patient, diagnosed with peri-implant mucositis underwent treatment with an Er:YAG laser (test) or an ultrasonic scaler (control) randomly.
Long-term clinical outcomes of isolated orbital floor fracture reconstruction using nonresorbable implants.
Indian J Ophthalmol
February 2025
Department of Ophthalmology, Faculty of Medicine, Fayoum University, Al Fayoum, Egypt.
Purpose: There are no universally established guidelines for material selection in orbital wall fracture reconstruction. With an increasing preference for permanent implants, this study aimed to compare the long-term clinical outcomes of three different non-resorbable materials in reconstructing isolated orbital floor fractures.
Design: A retrospective, interventional comparative study.
Reactions of Hydrogen-Passivated Silicon Vacancies in -Quartz with Electron Holes and Hydrogen.

We used density functional theory with a hybrid functional to investigate the structure and properties of [4H] (hydrogarnet) defects in -quartz as well as the reactions of these defects with electron holes and extra hydrogen atoms and ions. The results demonstrate the depassivation mechanisms of hydrogen-passivated silicon vacancies in -quartz, providing a detailed understanding of their stability, electronic properties, and behaviour in different charge states. While fully hydrogen passivated silicon vacancies are electrically inert, the partial removal of hydrogen atoms activates these defects as hole traps, altering the defect states and influencing the electronic properties of the material.

Since the biological activities and toxicities of 'foreign' and/or excess levels of metal ions are predominantly determined by their precise molecular nature, here we have employed high-resolution H NMR analysis to explore the 'speciation' of paramagnetic Ni(II) ions in human saliva, a potentially rich source of biomolecular Ni(II)-complexants/chelators. These studies are of relevance to the corrosion of nickel-containing metal alloy dental prostheses (NiC-MADPs) in addition to the dietary or adverse toxicological intake of Ni(II) ions by humans. Unstimulated whole-mouth human saliva samples were obtained from n = 12 pre-fasted (≥8 h) healthy participants, and clear whole-mouth salivary supernatants (WMSSs) were obtained from these via centrifugation.
