Giant cell tumor of the cervical spine: A case report.

Introduction: A Giant Cell Tumor (GCT) of the bone is a locally osteolytic tumor made up of mononuclear ovoid stromal cells and multinucleated giant cells. It commonly affects long bones like the distal femur and proximal tibia, but can also develop in the cervical spine during the third and fourth decades of life.

Evaluation of different tightening protocols on angled screw channel abutments after cyclic loading: An in vitro study.

Statement Of Problem: Screw loosening remains one of the most common complications associated with implant-supported restorations. The available literature is scarce regarding the most efficient method of tightening definitive abutment screws for angled screw channel (ASC) abutments.

Purpose: The purpose of this in vitro study was to identify the optimal screw tightening protocol for ASC abutments by evaluating the influence of different protocols on reverse tightening values (RTVs).

A case report of simultaneous tears of the medial and lateral posterior meniscal roots with an intact ACL graft.

Introduction And Importance: Meniscal root tears are defined as soft-tissue and/or osseous injuries that rip or avulse within one centimeter of the meniscal insertion to the tibial plateau. These injuries impact around 100,000 patients a year and make up 10 % to 21 % of all meniscal tears. Meniscal extrusion frequently happens when there are root rips, and the transmission of circumferential hoop loads is hampered.

Maxillary and mandibular implant rehabilitation using a completely digital workflow: A technique.

Complete arch implant scanning is a technique-sensitive procedure involving challenges acquiring the data, using an intraoral scanner, and aligning the obtained scans. A novel technique using a fixed custom scan body with a specific geometry is presented to allow virtual alignment and articulation at the optimal occlusal vertical dimension and centric relation position. The technique is accomplished by relating the geometric position of scan bodies, the interim prosthesis, and the custom scan body with a completely digital workflow.

Sternoclavicular Septic Arthritis and Surgical Intervention: A Case Report.

Management of septic arthritis is an area of controversy, especially in rare locations like the sternoclavicular joints. In this case report, we present a case of septic sternoclavicular joint, which was resistant to medical treatment and deteriorated during the treatment course. Although medical treatment has proven effective based on previous literature, some cases will still not benefit from it.

Antioxidant, carbonic anhydrase inhibition and diuretic activity of Forssk. Decne.

Background: Forssk. Decne is a member of family Apocynaceae and locally known as 'Khipp'. It is found in dry, sandy habitat of Pakistan and in several other regions around the world including Asia, Tropical Africa, Western Gulf and Mediterranean countries.

Assessment of heavy metal distribution, risk, and sourcing in mangrove sediments from three Saudi Arabian Red Sea locations.

This work measured the concentration of heavy metal cations (V, Cr, Ni, Cu, Zn, Cd, and Pb) and associated anionic ligands (SOM, carbonate, and silicate) in mangrove sediment samples from the Red Sea of Saudi Arabia to set a biogeochemical baseline within these as yet poorly constrained sensitive ecosystems. Sediments were collected from three regions along the Saudi Arabian coast: Yanbu, Jeddah, and the Farasan Islands. Risk indices and statistical analyses were applied to assess contamination levels and potential sourcing.

Effect of implant abutment screw materials and tightening protocols on reverse tightening values: An in vitro study.

Unlabelled: STATEMENT OF PROBLEM: Implant abutment screw loosening is the most common prosthetic complication of implant-supported single crowns. However, few studies have objectively evaluated the effectiveness of different tightening protocols on reverse tightening values (RTVs).

Purpose: The purpose of this in vitro study was to determine the optimal tightening protocol for implant abutment screws with different screw materials.
