Acute abdominal pain, defined as nontraumatic abdominal pain lasting fewer than seven days, is a common presenting concern with a broad differential diagnosis. The most common causes are gastroenteritis and nonspecific abdominal pain, followed by cholelithiasis, urolithiasis, diverticulitis, and appendicitis. Extra-abdominal causes such as respiratory infections and abdominal wall pain should be considered. ⋯ Point-of-care ultrasonography can aid in the prompt diagnosis of several etiologies of acute abdominal pain, including cholelithiasis, urolithiasis, and appendicitis. In patients who have female reproductive organs, diagnoses such as ectopic pregnancy, pelvic inflammatory disease, and adnexal torsion should be considered. If ultrasonography results are inconclusive in pregnant patients, magnetic resonance imaging is preferred over computed tomography when available.

Chronic Obstructive Pulmonary Disease: Diagnosis and Management.
Chronic obstructive pulmonary disease (COPD) affects nearly 6% of Americans. Routine screening for COPD in asymptomatic adults is not recommended. Patients with suspected COPD should have the diagnosis confirmed with spirometry. ⋯ Mucolytics, antitussives, and methylxanthines do not improve symptoms or outcomes. Long-term oxygen therapy improves mortality in patients with severe resting hypoxemia or with moderate resting hypoxemia and signs of tissue hypoxia. Lung volume reduction surgery reduces symptoms and improves survival in patients with severe COPD, whereas a lung transplant improves quality of life but does not improve long-term survival.
