Secondary infection in COVID-19 critically ill patients: a retrospective single-center evaluation.

Background: Patients infected with severe acute respiratory syndrome coronavirus (SARS-CoV-2) can develop severe illness necessitating intensive care admission. Critically ill patients are susceptible for the development of secondary bacterial infections. Due to a combination of virus- and drug-induced immunosuppression, critically ill patients with corona virus disease 2019 (COVID-19) may even have a higher risk of developing a secondary infection.

Ultrasonography and computed tomography of afferent loop obstruction.

The US and CT findings in a case of afferent loop obstruction after total gastrectomy are reported. A U-shaped fluid filled tubular structure crossing the midline between the abdominal aorta and the superior mesenteric artery (SMA) is a characteristic US and CT image of an afferent loop obstruction. CT is helpful to recognize the bowel wall and to demonstrate its relationship with the biliary system.

Value of MRI in the diagnosis and staging of testicular tumors.

Ultrasound is currently the primary imaging modality for the assessment of scrotal disease. In acute pathology, colour Doppler adds further confirmation about blood flow to the testicles and surrounding structures. MR is emerging as a powerful tool to image the scrotum.
