The diagnosis of polyneuropathy (PNP) is based on the anamnesis and description of complaints of the patient and clinical findings. The type of distribution as well as known diseases and drug toxic factors can provide indications. Electromyography and electroneurography can be used to differentiate between axonal and demyelinating PNP. ⋯ Depending on the neuropathy and context, the diagnostic approach is structured differently. The special diagnostics for small fiber neuropathy and amyloid neuropathy as well as for diabetes and alcohol abuse are dealt with in detail in this article. Numerous cases of polyneuropathy remain unexplained and regularly have a favourable prognosis.

Chronic lymphocytic leukemia (CLL) is one of the most common hematological neoplasms and is the most common leukemia in western industrial nations. According to the World Health Organization classification, CLL is an indolent B‑cell non-Hodgkin's lymphoma (NHL). Diagnosis requires an increase of B‑lymphocytes to more than 5.0 G/l as well as detection of CD5- and CD19-positive B‑lymphocytes. ⋯ The prognosis strongly depends on the individual molecular and cytogenetic risk factors. For a long time, the first-line treatment was characterized by chemotherapy in combination with CD20 antibodies. In recent years, the approval of new targeted drugs has changed the treatment landscape significantly and has led to a shift towards chemotherapy-free regimens.
