Adverse Event: Warfarin‐related nephropathy. Drug Implicated: Warfarin. The Patient: A 31‐year‐old female, managed with warfarin for rheumatic heart disease with atrial fibrillation. Evidence that Links the Drug to the Event: There were no alternative causes of nephropathy that could have caused the adverse event in this patient. Management: Shifting the drug from warfarin to acenocoumarol. Mechanism: Difference in renal elimination between warfarin and acenocoumarol. Implication for Therapy: Clinicians should be aware of this rare adverse effect of warfarin, and acenocoumarol can be considered as an alternative therapy for this condition. Hypotheses to be Tested: Further prospectively designed studies are needed to consider acenocoumarol as an alternative therapy in warfarin‐related nephropathy. [ABSTRACT FROM AUTHOR]

Background: Mucormycosis is an invasive fungal infection. It is rare and commonly associated with fatal outcomes., Methods: We report two cases of thoracic mucormycosis in immunocompetent patients. First, is an immunocompetent child with mediastinal mass and extension into the pericardium and left atrium. The second is a young woman with a left pulmonary artery pseudoaneurysm., Results: The first patient could not be salvaged while the second patient was successfully managed with surgical intervention and systemic antifungal treatment., Conclusion: Mucormycosis should be considered as a differential diagnosis in the management of immunocompetent patients in patients with pyrexia of unknown origin and a mediastinal mass. Early and aggressive surgical management along with systemic antifungal treatment improves the survival in this subset of patients., (© 2021 Wiley Periodicals LLC.)
