Legionnaires' disease (LD) is a serious sometimes fatal pneumonia caused by Legionella pneumophila. The clinical manifestations of LD may be similar to those by caused by Streptococcus pneumoniae. As both conditions can be serious illnesses but requiring different antimicrobial therapies, factors that can help differentiate these types of pneumonias can be helpful in the clinical management of hospitalized patients with bacterial pneumonia. This study aimed to compare clinical features and indicators of disease progression in hospitalized patients with community-acquired pneumonia caused by L. pneumophila and bacteremic S. pneumoniae. ⋯ Our data suggests that variables that may distinguish LD from S. pneumoniae include male gender, diarrhea, hyponatremia, higher temperature on admission, higher BMI and fewer comorbidities. Bacteremic S. pneumoniae was associated with poorer outcomes than LD including higher rates of septic shock, mechanical ventilation, ICU admission, and death.

Review Case Reports
An Unusual Case of Explosive Pleuritis without Mediastinal Shift.
Explosive pleuritis (EP) is an under-reported condition. Although there is no agreed-upon definition, generally, the term EP denotes a dramatic clinical and radiologic progression of pleural space inflammation in the setting of pneumonia. The pleural space inflammation leads to the formation of loculated complex pleural effusion or empyema, and pleural adhesion within a matter of hours, typically in less than 24 hours. ⋯ Streptococcal pneumonia is the most common cause of EP. Here we present a case and discuss the clinical, microbiologic, radiologic, and treatment aspects of EP. We also scrutinize the medical literature to compare the previously reported cases.

Coronavirus disease 2019 (COVID-19) can progress to cardiovascular complications which are linked to higher in-hospital mortality rates. Infective endocarditis (IE) can develop in patients with recent COVID-19 infections, however, characterization of IE following COVID-19 infection has been lacking. To better characterize this disease, we performed a systematic review with descriptive analysis of the clinical features and outcomes of these patients. ⋯ Our systematic review provides a profile of clinical features and outcomes of patients with a prior COVID-19 infection diagnosis who subsequently developed IE. Due to the ongoing COVID-19 pandemic, it is essential that clinicians appreciate the possibility of IE as a unique complication of COVID-19 infection.
