Abdominopelvic CT in COVID-19 patients with abdominal complaints including both waves and controls: reader agreement and overcalls after consensus review.

Background: Since many COVID-19 publications lack consensus reviews or controls, interpretive accuracy is unclear; abdominal processes unique or infrequent during the pandemic remain unknown. The incidence and nature of CT findings accounting for abdominal complaints in COVID patients, reader agreement and overcalling will be determined.

Methods: A retrospective study was performed on COVID patients with abdominal complaints from 3/15/2020-5/31/2020 and 11/1/2020-4/15/2021 including matched controls.

Cardiovascular Involvement of a CD138-Negative Anaplastic Myeloma: A Diagnostic Dilemma.

Anaplastic myeloma (AM) is an extremely rare and aggressive histological variant of myeloma. It is characterized by extramedullary presentation in the young and has a poor prognosis. It can be a diagnostic challenge when myeloma is not suspected and even more when the immunophenotype is unexpected.

Re-Identification Risk in HIPAA De-Identified Datasets: The MVA Attack.

We present a re-identification attack that uses indirect (non-HIPAA) identifiers to target a vulnerable subset of records de-identified to the HIPAA Safe Harbor standard, those involving motor vehicle accidents (MVAs). Documentation of an MVA in a patient note creates a significant risk to patient privacy through the MVA re-identification attack, with a relative risk of 537 compared to the general population. Patients in a significant MVA resulting in either permanent injury, hospitalization or death (for any victim) should have the accident location information omitted due to the significant risk of re-identification of HIPAA de-identified data.
