Diuretics are key elements of the pharmacotherapy of diseases in internal medicine. Currently, they are particularly used in the treatment of edema and hypertension. For the treatment with diuretics some rules exist that help to improve the effectiveness and success. The article explains these rules, especially regarding combination treatment and meaningful dose escalation. Additionally, the side effects of treatment are critically discussed. ⋯ There is little evidence for the influence of diuretics in the treatment of edema on prognostic factors, such as mortality and comorbidities. For an improvement of the prognosis other substances are more important, e.g. angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers; however, diuretics in the treatment of hypertension show clear positive effects on the endpoints. In recent years a problem of side effects was demonstrated (skin cancer). Comparing the benefits regarding prognosis in the treatment of hypertension with the side effects, the administration but with appropriate protective measures seems to be warranted.

Hepatitis viruses A-E cause acute and chronic liver inflammation and thus lead to significant morbidity and mortality worldwide. They differ significantly in their biology, course of disease and therapy options. While hepatitis A virus only causes acute infection, hepatitis B can become chronic, even reactivate or occur as coinfection with hepatitis D virus. ⋯ However, new direct antiviral agents reliably lead to cure of chronic hepatitis C. Hepatitis E virus frequently causes acute or-in case of immunosuppression-even chronic hepatitis. Continual screening of patients with elevated liver enzymes or risk groups using simple serological markers can enable virus-specific therapy of mostly asymptomatic chronic virus hepatitis, preventing the development of liver cirrhosis and hepatocellular carcinoma.

Case Reports
[Right upper abdominal pain, vomiting, weight loss and icterus in a 20-year-old male refugee].
Tuberculosis (TB) is one of the most common infectious diseases worldwide. The case of a 20-year old male refugee from Somalia, who initially presented with right-sided upper abdominal pain, vomiting, weight loss and jaundice with suspected cholecystitis is reported. In the course of further diagnostics, pyloric stenosis surprisingly appeared, which, like the cholestasis, was caused by compressing peripancreatic lymph nodes. Lymph node cytology finally showed evidence of caseating necrosis with evidence of TB pathogens.

Abdominal pain is a frequent cause of consultation to doctors' offices and emergency rooms. The most common differential diagnoses can be confirmed with readily available, cost-effective, and low-risk diagnostic tools such as laboratory tests, ultrasound, or gastroscopy. Additional diagnostic tests are required to exclude rare causes such as small, solid, or hematological malignancies, metabolic disorders, or polyneuropathies of varying origin. In the following, we present the case of a patient with severe epigastric pain due to neuroborreliosis, and recapitulate the diagnostic steps for clarifying abdominal pain using this example.
