RESUMO
Amiodarone is an antiarrhythmic agent that is used commonly in clinical practice. It is associated with many side effects, the most common being pulmonary manifestations. Interstitial pneumonitis is one of the most common complications, however rarely amiodarone can cause diffuse alveolar haemorrhage (DAH) too. We describe the case of a 73-year-old woman who presented with shortness of breath and haemoptysis 4 days after starting amiodarone. She was diagnosed with amiodarone-induced DAH based on imaging and bronchoalveolar lavage. She was treated with intravenous and then oral steroids, and amiodarone was discontinued. The patient made a significant clinical and radiological recovery. She was discharged 10 days after her presentation. This case highlights a rare but potentially life-threatening complication of a commonly used medication.

Human cytomegalovirus (CMV) is a double-stranded DNA virus that can cause widespread severe infection in immunocompromised individuals but is more typically a subclinical infection in immunocompetent individuals. Rarely, it can cause a serious infection in immunocompetent individuals. Here, we describe a 36-year-old otherwise healthy male who presented with fever, cough and malaise who was diagnosed with CMV pneumonia. He made a rapid recovery after initiation of ganciclovir and has been doing well on follow-up visits. We performed a comprehensive review of CMV pneumonia in immunocompetent individuals and have summarised the prior 16 reported cases of CMV pneumonia in immunocompetent patients. This article highlights the importance of considering CMV as a cause of pneumonia even in immunocompetent individuals, especially when the more common causes have been excluded. Early diagnosis allows prompt treatment and potentially complete recovery.

Felty syndrome, a rare extra-articular manifestation of rheumatoid arthritis (RA), usually affects patients with long-standing disease. Patients with this syndrome typically present with neutropenia, splenomegaly, in addition to erosive RA. The development of unexplained neutropenia in healthy patients should prompt the work up for Felty syndrome, especially in patients with suggestive demographics, signs, and symptoms. Differentiation between large granular lymphocyte (LGL) leukemia and Felty syndrome is necessary as both can present with neutropenia, and are associated with RA. Immunosuppressive therapy has improved the prognosis of patients with Felty syndrome given the decreasing rates of splenectomies done in those patients over the last decades.
