Acute pericarditis is defined as inflammation of the pericardium and occurs in approximately 4.4% of patients who present to the emergency department for nonischemic chest pain, with a higher prevalence in men. Although there are numerous etiologies of pericarditis, most episodes are idiopathic and the cause is presumed to be viral. Diagnosis of pericarditis requires at least two of the following criteria: new or worsening pericardial effusion, characteristic pleuritic chest pain, pericardial friction rub, or electrocardiographic changes, including new, widespread ST elevations or PR depressions. ⋯ Glucocorticoids should be reserved for patients with contraindications to first-line therapy and those who are pregnant beyond 20 weeks' gestation or have other systemic inflammatory conditions. Colchicine should be used in combination with first- or second-line treatments to reduce the risk of recurrence. Patients with a higher risk of complications should be admitted to the hospital for further workup and treatment.

ReviewEvaluation and Treatment of Nausea and Vomiting in Adults.
Nausea and vomiting are common symptoms that can reduce quality of life and indicate life-threatening illness. Acute nausea and vomiting last up to 7 days. In the absence of alarm symptoms, they are typically treated symptomatically and without an extensive evaluation. ⋯ When a specific etiology is not identified, a serotonin antagonist or dopamine antagonist can be used. However, medications may also target the suspected cause of symptoms and the neurotransmitters involved in central and peripheral pathways of nausea and vomiting. Pharmacologic therapy should be used for the shortest time necessary to control symptoms.

ReviewAtrial Fibrillation: Common Questions and Answers About Diagnosis and Treatment.
Atrial fibrillation is a supraventricular arrhythmia that increases the risk of stroke and all-cause mortality. It is the most common cardiac dysrhythmia in adults in the primary care setting, and its prevalence increases with age. The U. ⋯ Rhythm control, using medications or procedures, should be considered in patients with hemodynamic instability or in some patients based on risk factors and shared decision-making. Electrical cardioversion may be appropriate as first-line rhythm control. Conversion to sinus rhythm with catheter ablation may be considered in patients who are unable or unwilling to take rate or rhythm control medications long-term or if medications have been ineffective.
