Acute respiratory distress syndrome caused by : a case report and literature review.

Background: Psittacosis is a zoonotic disease with a low incidence rate and a lack of specificity in clinical manifestations, making it prone to be missed, misdiagnosed, and even cause delayed treatment for patients. Metagenomic next-generation sequencing (mNGS) was successfully performed for the diagnosis of a young patient with psittacosis progressing to acute respiratory distress syndrome (ARDS), and precisely targeted antibiotic treatment was promptly administered. Additionally, a comprehensive review was conducted on 68 cases of psittacosis complicated with ARDS, with the goal of improving the clinical awareness of this disease.

Clinical characteristics and aetiological analysis of 133 patients for pulmonary embolism combined with haemoptysis.

Background: In the patients with pulmonary embolism (PE), PE itself can cause haemoptysis and other reasons can also cause haemoptysis. Therefore, the clinical characteristics and the causes of haemoptysis are lacking.

Methods: A retrospective analysis was performed that involved screening 583 PE patients and determining that haemoptysis occurred in 141 cases.
