Jaundice is an indication of hyperbilirubinemia and is caused by derangements in bilirubin metabolism. It is typically apparent when serum bilirubin levels exceed 3 mg/dL and can indicate serious underlying disease of the liver or biliary tract. A comprehensive medical history, review of systems, and physical examination are essential for differentiating potential causes such as alcoholic liver disease, biliary strictures, choledocholithiasis, drug-induced liver injury, hemolysis, or hepatitis. ⋯ Measuring fractionated bilirubin allows for determination of whether the hyperbilirubinemia is conjugated or unconjugated. Ultrasonography of the abdomen, computed tomography with intravenous contrast media, and magnetic resonance cholangiopancreatography are first-line options for patients presenting with jaundice, depending on the suspected underlying etiology. If the etiology of jaundice is unclear despite laboratory testing and imaging, liver biopsy may be required to establish the diagnosis, prognosis, and management of the disease.

ReviewDysuria: Evaluation and Differential Diagnosis in Adults.
Dysuria, a feeling of pain or discomfort during urination, is often caused by urinary tract infection but can also be due to sexually transmitted infection, bladder irritants, skin lesions, and some chronic pain conditions. History is most often useful for finding signs of sexually transmitted infection, complicated infections, lower urinary symptoms in males, and noninfectious causes. Most patients presenting with dysuria should have a urinalysis performed. ⋯ Clinical decision rules may increase the accuracy of diagnosis with and without laboratory analysis. Evaluation and treatment of dysuria through a virtual encounter without laboratory testing may increase recurrent symptoms and antibiotic courses. Persistent symptoms after initial evaluation and treatment require further workup for infectious and noninfectious causes.
