Wells Score to Predict Pulmonary Embolism in Patients with Coronavirus Disease 2019.

Background: The association between coronavirus disease 2019 (COVID-19) and hypercoagulability has been extensively described, and pulmonary embolism is a recognized complication of COVID-19. Currently, the need for computed tomography pulmonary angiogram (CTPA) relies on the Wells score and serum D-dimer levels. However, because COVID-19 patients have a different thrombotic and inflammatory milieu, the usefulness of the Wells score deserves further exploration for this patient population.

Mycobacterium fortuitum infection of the scalp after a skin graft.

Mycobacterium fortuitum is a non-tuberculous mycobacterium found in the soil and water of most regions of the world, and it can cause disease in immunocompetent and immunocompromised hosts. We present a 52-year-old man who developed a scalp abscess under a free flap for cranium coverage after a motor vehicle accident. Culture of material drained from the abscess grew M.

Association of membranoproliferative glomerulonephritis with mantle cell lymphoma.

Mantle cell lymphoma (MCL) is a rare and aggressive lymphoid neoplasm. It can involve the kidney, either by direct lymphomatous infiltration or by a paraneoplastic glomerulonephritis. We present here the case of a man with rectal bleeding and rapidly progressive renal failure, who had MCL in the gastrointestinal tract and paraneoplastic membranoproliferative glomerulonephritis, and whose renal dysfunction normalised after chemotherapy.
