Pembrolizumab-induced Myasthenia Gravis and Myocarditis.

As the use of immune checkpoint inhibitors (ICPi) such as pembrolizumab is rapidly expanding in the field of immuno-oncology, it is crucial for healthcare providers to be aware of their immune-related adverse events (irAE) which are thought to be driven by augmented immune response of T-cells. While neurologic irAE are underrepresented in literature, their consequences could lead to fatal outcomes. In this report, we describe the case of a patient with excellent performance status prior to pembrolizumab therapy who subsequently suffered myasthenic crisis eventually requiring tracheostomy and long-term mechanical ventilation.

Gemcitabine induced pneumonitis: a case report and review of literature.

We are reporting a case of pneumonitis in an 81 year old-aged woman due to gemcitabine who was successfully managed with steroids. We also reviewed the literature and found previous case reports of gemcitabine induced pneumonitis.We reported this case to alert physicians to be aware of this infrequent and sometimes fatal complication from gemcitabine.
