AI Article Synopsis
- The study aimed to assess how a nanotextured dental implant treated with sodium sulfate affects early bone response in a rabbit model.
- Twelve rabbits were divided into two groups: one with standard machined implants (Control) and the other with the nanotextured implants (Test), with histological analysis done three weeks post-surgery.
- Results showed that the nanotextured group had significantly greater bone contact (27%) compared to the control group, indicating that sodium sulfate anodization enhances osseointegration.
Article Abstract
Purpose: To evaluate the early bone response to a nanotextured dental implant treated with sodium sulfate (Na2SO4), using a rabbit model.
Methods: Twelve animals were randomly divided into group 1 (Control) - machined implants and group 2 (Test) - nanotextured implants. Extra-oral incision was performed to provide access to intended surgical site where the dental implant was inserted immediately after the extraction of the mandibular first premolar. Implant surface characterization was performed by scanning electron microscopy attached to energy dispersive spectroscopy and interferometry. Three weeks after surgery, the animals were induced to death and undecalcified sections of the samples were prepared for histological and histomorphometrical analysis.
Results: Surface characterization of the implant demonstrated enhanced surface area of anodized group compared to Control group with 19.2% ± 6.2 versus 1.6 ± 0.7, respectively. Histological evaluation demonstrated new bone formation starting from the buccal and lingual cortical walls on both groups. After three weeks, significant higher bone contact of 27% (p<0.05) was observed to nanotextured compared to machined implants (Control group).
Conclusion: The anodization with sodium sulfate nanostructures to the implant surface that resulted in faster osseointegration.

Utility values of responders and nonresponders are essential inputs in cost-effectiveness studies of radiation therapy for painful bone metastases but, to our knowledge, they have not been reported separately. We sought to determine the utility values of responders and nonresponders using data from a prospective observational study on bone metastases. The original prospective observational study was conducted at 26 centers in Japan.

This post-marketing surveillance (PMS) assessed the safety and effectiveness of isatuximab plus pomalidomide and dexamethasone (Isa-Pd) for relapsed or refractory multiple myeloma (RRMM) in frail individuals during real-world use in Japan. Data from all individuals with RRMM treated with Isa-Pd in Japan between October 2020 and October 2021 were collected, with follow-up continued up to 12 months after starting Isa-Pd or until discontinuation. In the overall PMS population, 40 participants were classified as frail (33.

Background And Aim: Osteoid osteoma (Oo) and osteoblastoma (Ob) are rare primary bone tumors with a higher prevalence in the second decade of life. Treatment can be conservative, but in cases of spinal location, resective surgery is of great importance but may be challenging.
Material And Methods: We report four pediatric cases of Oo and Ob managed in our unit, with different locations at the level of the cervical spine.

Purpose: [F]NaF PET has become an increasingly important tool in clinical practice toward understanding and evaluating diseases and conditions in which bone metabolism is disrupted. Full kinetic analysis using nonlinear regression (NLR) with a two-tissue compartment model to determine the net rate of influx (K) of [F]NaF is considered the gold standard for quantification of [F]NaF uptake. However, dynamic scanning often is impractical in a clinical setting, leading to the development of simplified semi-quantitative parameters.

: The primary objective of this study was to investigate clinical manifestations, time to diagnosis, and number of biopsies in patients with extranodal natural killer T-cell lymphoma (ENKTL). The secondary objectives were to determine response rates, survival outcomes, prognostic factor for overall survival (OS), and validation of the Prognostic Index of Natural Killer Lymphoma (PINK), Ann Arbor staging system (AASS), and the CA system. : This retrospective study included data pertaining to patients with newly diagnosed ENKTL in Chiang-Mai University Hospital from 2004 to 2020.
