[Endoscopic diagnosis, treatment, and follow-up of polyps of the lower gastrointestinal tract].
The endoscopic management of polyps of the lower gastrointestinal tract (l-GIT) has emerged in recent years as a result of numerous technological innovations. However, proven expertise and experience are essential. ⋯ Adequate characterization and treatment are essential for the appropriate management of l‑GIT polyps.

Review
[Endoscopic diagnosis, treatment, and follow-up of polyps of the upper gastrointestinal tract].
Polyps occur significantly less frequently in the upper gastrointestinal tract compared to the lower gastrointestinal tract. They are usually incidental findings at esophagogastroduodenoscopy. A distinction is made between epithelial lesions and subepithelial tumors. ⋯ For subepithelial tumors, advanced procedures such as endoscopic submucosal dissection (ESD), submucosal tunneling endoscopic resection (STER), or endoscopic full-thickness resection are available. These procedures should primarily be performed at centers with appropriate expertise. Endoscopic follow-up is primarily determined by the tumor entity and the resection status.

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.

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.
