Posterior Lumbar Facet Replacement and Arthroplasty.

Neurosurg Clin N Am 2021 Oct 29;32(4):521-526. Epub 2021 Jul 29.

Department of Neurosurgery, Perelman School of Medicine, University of Pennsylvania, 3rd Floor, Silverstein Pavilion, 3400 Spruce Street, Philadelphia, PA 19104, USA.

There is an ongoing desire for the development of motion-preserving facet replacement devices as an alternative to rigid fixation in hopes of better preserving the natural kinematics of the lumbar spine. Theoretically, such a construct would simultaneously address pain associated with spinal instability and prevent abnormal load distribution and adjacent segment degeneration. Several such devices have been developed including the Anatomic Facet Replacement System, the Total Facet Arthroplasty System, and the Total Posterior Arthroplasty System. Read More

Calcaneal Fractures-Which Approach for Which Fracture?

Orthop Clin North Am 2021 Oct 29;52(4):433-450. Epub 2021 Jul 29.

Michigan Orthopedic Center, Sparrow Hospital, 2815 S. Pennsylvania Avenue, Suite 204 Lansing, MI 48910, USA.

Treatment of calcaneal fractures has to be tailored to the individual pathoanatomy. If operative treatment is chosen, anatomic reconstruction of the calcaneal shape and joint surfaces is mandatory. For most of the displaced, intraarticular fractures, this can be achieved by less invasive reduction and fixation via a sinus tarsi approach, which may be extended along the "lateral utility" line for calcaneocuboid joint involvement or calcaneal fracture-dislocations.

Electronic address:

Ankle fractures are common injuries to the lower extremity with approximately 20% sustaining a concomitant injury to the syndesmosis. Although the deltoid ligament is not formally included in the syndesmotic complex, it plays an important role in the mortise stability. Therefore, its integrity should be always evaluated when syndesmotic injury is suspected. Read More

Cancer Control 2021 Jan-Dec;28:10732748211033544

Department G.F. Ingrassia, Section of Anatomic Pathology, 60279University of Catania, Catania, Italy.

Background: A possible oncogenic role of human papillomavirus (HPV) in head and neck cancers (mainly oropharynx tumors) has been suggested. This significant association has been considered true for oropharynx tumors; however, the association between HPV infection and laryngeal carcinomas is yet to be established. The aim of this study was to evaluate the relationship between p16 expression and long-term overall, disease-free, and disease-specific survival (OS, DF, and DSS, respectively) in patients surgically treated for laryngeal carcinoma.

Epstein-Barr virus associated gastric dysplasia: a new rare entity?

Virchows Arch 2021 Sep 19. Epub 2021 Sep 19.

Department of Medicine (DIMED), Surgical Pathology & Cytopathology Unit, University of Padua, via Gabelli 61, 35121, Padua, Italy.

Epstein-Barr virus (EBV) infection characterizes a portion of gastric adenocarcinomas. However, since there is lack of evidence of EBV presence in pre-neoplastic lesions of gastric mucosa, the etiologic role of EBV in gastric carcinogenesis is still debated. We report an unusual case of an EBV-associated foveolar gastric dysplasia associated with a focus of EBV-positive low-grade tubular adenocarcinoma, arisen in the context of a lymphocytic-like (EBV-positive) gastritis.

Advancements in Positron Emission Tomography/Magnetic Resonance Imaging and Applications to Diagnostic Challenges in Neuroradiology.

Semin Ultrasound CT MR 2021 Oct 1;42(5):434-451. Epub 2021 Aug 1.

Department of Radiology, Northwestern University, Feinberg School of Medicine, Chicago, IL. Electronic address:

Since the clinical adoption of magnetic resonance (MR) in medical imaging, MR has proven to be a workhorse in diagnostic neuroradiology, with the ability to provide superb anatomic detail as well as additional functional and physiologic data, depending on the techniques utilized. Positron emission tomography/computed tomography has also shown irreplaceable diagnostic value in certain disease processes of the central nervous system by providing molecular and metabolic information through the development of numerous disease-specific PET tracers, many of which can be utilized as a diagnostic technique in and of themselves or can provide a valuable adjunct to information derived from MR. Despite these advances, many challenges still remain in neuroradiology, particularly in malignancy, neurodegenerative disease, epilepsy, and cerebrovascular disease. Read More

Department of Family Medicine and Public Health, University of California, San Diego The Library, University of California, San Diego FHI 360, Jakarta, Indonesia Division of Infectious Diseases and Global Public Health, Department of Medicine, University of California, San Diego.

Background: Pooled testing for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) may be a cost-saving solution to increase screening by simplifying testing procedures and reducing resource burdens. We conducted a systematic review and meta-analysis to examine the performance of pooled three-anatomical site testing (pharyngeal, rectal, and urogenital sites) for CT and NG in comparison to single-anatomical site testing.

Methods: We conducted a systematic literature search in PubMed, Embase, and Web of Science to identify original evaluation studies of the performance of pooled testing for CT and NG infections and identified 14 studies for inclusion. Read More
