Metabolic Activity Assessment by 18F-Fluorodeoxyglucose Positron Emission Tomography in Patients after COVID-19 Vaccination.

In the following report, we describe 11 patients with various diagnoses and different treatment statuses (newly diagnosed, receiving treatment, or follow-up) of oncological diseases (breast, lymphoma, melanoma, and head and neck cancers). The patients underwent PET-CT for disease staging or follow-up and it was noted that all patients had areas of hypermetabolic uptake in the axillary lymph-nodes of the ipsilateral upper extremity where the Pfizer-BioNTech coronavirus (COVID-19) vaccine was administered. Following further investigations, including an ultrasound (US), biopsies and an examination of medical records, it was concluded that these findings were the result of the vaccination and not a progression of pre-existing disease.

Bisphosphonate treatment and the risk of atypical femoral fracture among patients participating in a Fracture Liaison Service of a tertiary medical center.

Unlabelled: Bisphosphonates are common treatment for osteoporosis. Among patients admitted with hip fracture, atypical femoral fractures (AFF) were more prevalent in those who were treated with Bisphosphonates for five or more years. Five years of Bisphosphonates treatment may signify an increased risk for AFF, though the absolute risk remains very low.

Jejunal obstruction caused by migrated gastric band.

We describe the rare complication of an eroded gastric band in the gastric cavity that passed through the pylorus and obstructed the proximal jejunum at the point allowed by the length of the connecting tube. At surgery, in addition to the expected finding, multiple necrotic pressure ulcerations in the jejunal wall were found in step ladder locations. Anyone who has adopted laparoscopic gastric banding as the modality for surgical treatment of morbid obesity should be familiar with this rare but potentially dangerous complication.

Primary aortoduodenal fistula: Pitfalls and success in the endoscopic diagnosis.

Primary aortoenteric fistula is a rare but catastrophic cause of gastrointestinal bleeding. The diagnosis of primary aortoenteric fistula is difficult to make and is usually accompanied by a very high level of clinical suspicion. It should be considered in any elderly patient presenting with upper gastrointestinal bleeding in the context of a known abdominal aortic aneurysm.

Accuracy of sonographically guided 14-gauge core-needle biopsy: results of 715 consecutive breast biopsies with at least two-year follow-up of benign lesions.

Purpose: The objective of this study was to examine the diagnostic accuracy of sonographically guided 14-gauge core-needle biopsy (CNB).

Methods: Sonographically guided 14-gauge CNBs of 715 breast lesions were performed in 652 patients. Histopathologic results were correlated with imaging findings, and repeat biopsy was recommended in the cases of discordance between the radiologic and pathologic results.
