title: Myasthenia gravis with acute respiratory failure in the emergency department.
abstract: Acute respiratory failure (ARF) is defined as a sudden malfunction in the ability of respiratory system to maintain adequate gas exchange. Acute hypercapnic respiratory failure develops as a result of ventilation deficiency and it is defined as an increase of PaCO2above 45 mmHg. Myasthenia Gravis (MG) is a sporadically developing auto-immune deficiency where the neuro-muscular transmission is affected and it is one of the important reasons for neurologically-induced respiratory distress. Here, we report a case of a 75-year-old male patient previously undiagnosed MG, who presented with ARF. MG is not a common entity that we encounter daily. Patients on occasions may present to the emergency department because of acute exacerbation. Though most of them were known cases, we should be aware of some unrecognized cases and should consider MG as a differential diagnosis for patients with acute respiratory failure.
