Does the presence of macroscopic intralesional fat exclude malignancy? An analysis of 613 histologically proven malignant bone lesions.

Objective: To determine if macroscopic intralesional fat detected in bone lesions on CT by Hounsfield unit (HU) measurement and on MRI by macroscopic assessment excludes malignancy.

Materials And Methods: All consecutive CT-guided core needle biopsies (CNB) of non-spinal bone lesions performed at a tertiary center between December 2005 and September 2021 were reviewed. Demographic and histopathology data were recorded.

MRI of patellar stabilizers: Anatomic visibility, inter-reader reliability, and intra-reader reproducibility of primary and secondary ligament anatomy.

Objective: To compare MRI features of medial and lateral patellar stabilizers in patients with and without patellar instability.

Methods: Retrospective study of 196 patients (mean age, 33.1 ± 18.

Virtual Residency Interviews- A Survival Guide and Lessons Learnt.

With the outbreak of Coronavirus Disease 2019 (COVID-19) pandemic, the residency programs were required to conduct virtual/online interviews for recruitment of candidates for their residency programs. While both programs and the candidates had challenges, with the abrupt transition of interviews to online platform, there were some perceived benefits by the applicants. This paper will further review the pros and cons, the challenges and the changes brought about by the online transformation of residency interviews and conclude with tips to the residency applicants and lessons learnt from this transition.

What is the Value of Radiology Input During a Multidisciplinary Orthopaedic Oncology Conference?

Background: Multidisciplinary orthopaedic oncology conferences are important in developing the treatment plan for patients with suspected orthopaedic bone and soft tissue tumors, involving physicians from several services. Past studies have shown the clinical value of these conferences; however, the impact of radiology input on the management plan and time cost for radiology to staff these conferences has not been fully studied.

Questions/purposes: (1) Does radiology input at multidisciplinary conference help guide clinical management and improve clinician confidence? (2) What is the time cost of radiology input for a multidisciplinary conference?

Methods: This prospective study was conducted from October 2020 to March 2022 at a tertiary academic center with a sarcoma center.

Troubleshooting Challenging Musculoskeletal Tumor Biopsies: Tricks of the Trade.

Image-guided core needle biopsy of musculoskeletal lesions can be challenging due to a variety of technical, patient-related, and lesion-related factors. Poor preprocedural planning can result in low diagnostic yield, misdiagnosis, delay in care, and the need for additional procedures. Furthermore, suboptimal procedural technique may place the patient at an increased risk of iatrogenic complications.

Distant migration of gluteal augmentation fat presenting as a soft tissue knee mass.

Gluteal augmentation with autologous fat grafting is an increasingly popular procedure. While complication rates are low, the clinical and imaging evaluation of the various complications can be challenging. We report a case of distal migration of a failed gluteal fat graft in a young female patient presenting as a soft tissue mass in the knee, mimicking a soft tissue sarcoma.

Association of aspirin and other non-steroidal anti-inflammatory drugs with bleeding complications in image-guided musculoskeletal biopsies.

Objective: To evaluate the safety of continuing aspirin and other non-steroidal anti-inflammatory drugs (NSAID) in patients undergoing image-guided musculoskeletal biopsies.

Material And Methods: Prior to October 2017, patients undergoing image-guided musculoskeletal biopsy had aspirin and NSAIDs withheld for the preceding 5-7 days. The policy changed in October 2017 based on new guidelines from the Society of Interventional Radiology such that aspirin and other NSAIDs were not withheld.

VDAC oligomers form mitochondrial pores to release mtDNA fragments and promote lupus-like disease.

Mitochondrial stress releases mitochondrial DNA (mtDNA) into the cytosol, thereby triggering the type Ι interferon (IFN) response. Mitochondrial outer membrane permeabilization, which is required for mtDNA release, has been extensively studied in apoptotic cells, but little is known about its role in live cells. We found that oxidatively stressed mitochondria release short mtDNA fragments via pores formed by the voltage-dependent anion channel (VDAC) oligomers in the mitochondrial outer membrane.

Estimating Sex Using Metric Analysis of the Scapula by Postmortem Computed Tomography.

Postmortem computed tomography (CT) has been extensively used in the last decade for identification purposes and in various anthropologic studies. Postmortem CT measurements of scapulae, analyzed using logistic discriminant function developed in this study, showed 94.5% accuracy in estimating sex.

Undersized Rigid Nonplanar Annuloplasty: The Key to Effective and Durable Repair of Functional Tricuspid Regurgitation.

Background: Previous clinical experiences have demonstrated high early and late recurrence rates after repair of functional tricuspid regurgitation (TR). We investigated the results of functional TR repair with undersized rigid nonplanar annuloplasty rings.

Methods: From January 2007 to December 2013, 216 consecutive patients with moderate or greater functional TR were treated with undersized (size 26 mm or 28 mm) rigid nonplanar annuloplasty rings.

Assessment of Injuries During Brazilian Jiu-Jitsu Competition.

Background: Brazilian jiu-jitsu (BJJ) is a unique style of martial arts with rapid growth in the United States and internationally. Although studies have examined injuries in other martial arts and combat sports, to date, no published medical study has examined injuries in BJJ competitions.

Purpose: (1) To estimate the incidence of injuries in BJJ competitions and (2) to identify and describe the types and mechanisms of injuries associated with competitive BJJ.
