Fluids and electrolytes are basic components of the human body and essential for the survival of most species. Any imbalance can potentially lead to serious conditions and death. The replacement of fluids and electrolytes has been used since the ancient age. Modern medicine still requires certain degree of expertise in these areas, which ranges from simple replacement in patients with mild illness to a more complex management in critically ill or hospitalized patients. Training and education in the evaluation and management of patients with fluids and electrolyte abnormalities are fundamental for patient’s outcomes. Severe sodium abnormalities are associated with increased morbidity and mortality, and they are markers of poor outcomes. This review presents a concise discussion of frequently asked questions in the evaluation and management of patients with fluids and sodium abnormalities.

Manifestations of Legionella infections range from benign, mild disease to a more severe form with increased morbidity and mortality, especially in untreated patients. Despite diagnostic advances, clinical diagnosis remains elusive. Macrolides and respiratory fluoroquinolones remain the antibiotics of choice for treatment of Legionella; however, several new antibiotics are currently under development or in clinical trials. The recommended duration of antibiotics is 5–7 days; although, some critically ill or immunosuppressed patients may require longer treatment. In vivo resistance to these antibiotics is rare, and there is no evidence that combination therapy is more beneficial than monotherapy. Early suspicion, diagnosis, and treatment are paramount for improving outcomes.
