Radiographic evaluation of bone density in dentulous and edentulous patients in Riyadh, KSA

Conclusion: Evaluation of bone density is an important step in treatment planning and this study was aimed to provide insight into bone density patterns of population in Riyadh, Saudi Arabia. Further similar studies in different populations can help in planning for more efficient treatment outcomes.

By STEPHEN BORSTELMANN, MD Occasionally, you get handed a question you know little about, but it’s clear you need to know more.  Like most of us these days, I was chatting with my colleagues about the novel coronavirus. It goes by several names: SARS-CoV-2, 2019-nCoV or COVID-19 but I’ll just call it COVID.  Declared a pandemic on March 12, 2020 by the World Health Organization (WHO), COVID is diagnosed by laboratory test – PCR.  The early PCR test used in Wuhan was apparently low sensitivity (30-60%), lengthy to run (days), and in short supply.  As CT scanning was relatively availa...

Conclusion: We recommend radiography or cone-beam computed tomography (CBCT) scanning for individual patients judged to require a cross-sectional image after reading of a panoramic X-ray image and a conventional intraoral radiological image. Various steps should be taken to raise awareness of these recommendations among clinicians and the public, and K-CIG should be regularly reviewed and revised. PMID: 32206620 [PubMed]

AbstractPurpose of ReviewThis review discusses imaging modalities for fracture repair assessment, with an emphasis on pragmatic clinical and translational use, best practices for implementation, and challenges and opportunities for continuing research.Recent FindingsSemiquantitative radiographic union scoring remains the clinical gold standard, but has questionable reliability as a surrogate indicator of structural bone healing, particularly in early-stage, complex, or compromised healing scenarios. Alternatively, computed tomography (CT) scanning enables quantitative assessment of callus morphometry and mechanics through ...

CONCLUSION: The current literature suggests that CT has several advantages over radiographs for preoperative planning of THA including more accurate planning of implant size, component alignment, and postoperative leg length. It is also superior to x-ray in identifying extraarticular hip deformities using the minimum effective dose for CT and the minimum scan length required by templating software. The radiation can be reduced to values similar to radiography. PMID: 32196566 [PubMed - as supplied by publisher]

The American College of Radiology (ACR) is urging radiologists to steer clear of CT scans and chest radiographs (CXR) as their first line of diagnostic defense of COVID-19 diagnosis and treatment, according to a recently issued statement. With the unpredictability of available testing kits and early reports of test sensitivity from China, health care providers are turning to imaging devices to detect infection symptoms. However, the ACR encourages healthcare providers to stick to viral testing, and explains why CT and CXR should be used at a minimum. Here are some takeaways from the official recommendation:The results from...

A  paperrecently published in theAmerican Journal of Roentgenologyhas found that scans of patients with COVID-19 share many similarities with imaging studies of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). According to the World Health Organization (WHO), the  pandemichas so far (as of the date of this article) resulted in over 191,000 cases and more than 7,800 deaths. Although most of those infected only have cold-like symptoms, about 16 percent are serious cases where patients suffer from pneumonia and breathing difficulties. Coronavirusesare responsible for bo...

We read with great interest the article by Young-Hoo Kim et al.(1) titled “Eighteen-Year Follow-Up Study of 2 Alternative Bearing Surfaces Used in Total Hip Arthroplasty in the Same Young Patients”, March 2020 issue, regarding comparison of functional, radiographic, and computed tomography scan outcomes and implant survivorship at a mean follow-up of 17 years of ceram ic-on-ceramic total hip arthroplasty (C-O-C THA) and ceramic-on-highly cross-linked polyethylene total hip arthroplasty (C-O-HXLPE THA) in the same patients.

J Neurol Surg B DOI: 10.1055/s-0040-1701692C1 fractures with an intact transverse ligament are usually treated conservatively. Patients who present with a progressive diastasis of bone fragments and a progressive articular subluxation mainly attributed to progressive lengthening of the transverse ligament (TAL) fibers can be treated with a C1 “C-clamp” fusion.A 75-year-old male who sustained a motor vehicle accident was neurologically intact. A computed tomography (CT) imaging demonstrated a Jefferson's type-C1 fracture with a slight lateral displacement of the C1 left lateral mass (LM) and a rotatory subluxati...

Abstract Historically, extra-articular scapular body fractures were treated nonsurgically, but displaced fractures of the glenoid neck can lead to dysfunction. Controversy exists regarding which extra-articular scapular fractures should be treated surgically; however, nonsurgical management of severely displaced scapular body fractures can result in satisfactory outcomes. Inclusion criteria for this study were medial or lateral displacement greater than 2 cm, angular deformity between fracture fragments greater than 45°, or glenopolar angle less than 22°. Functional outcomes included Disabilities of the Ar...
