Relationship between blood ammonia and plasma free amino acids concentration in adult-onset citrullinemia type 2: A case report
1.1. Aim: Elevated plasma citrulline (Cit) concentration is a char acteristic finding in adult-onset type II citrullinemia (CTLN2). However, the plasma free amino acids (PFAA) profile associated with ammonia detoxification has not been fully analyzed.
Spontaneous pneumothorax associated with COVID-19 is rare. We reported four cases and reviewed the literature. Among the reports, 29% and 42% were a-/oligosymptomatic or symptomatic but improving, respectively. Clinicians must be aware of this com plication because it can happen when the patient with COVID-19 was a-/oligosymptomatic or had improving symptoms.
