Vasculitic neuropathies result from inflammation of the vasa nervorum followed by ischemia and destruction of the peripheral nerve. The inflammation can be systemic or localized, i.e. non-systemic. Systemic vasculitis can be divided into primary and secondary forms. ⋯ The group of non-systemic neuropathies has grown in recent years with the addition of diabetic and non-diabetic lumbosacral radiculoplexus neuropathies, among others. Within the group of connective tissue diseases, other non-vasculitic neuropathies can occur as nerve-entrapment syndromes and sensory ataxic neuropathy. The aim of this article is to present a condensed overview of neuropathies associated with vasculitis and connective tissue diseases and to communicate characteristic clinical symptoms supporting rapid diagnostic and therapeutic procedures.

The treatment of polyneuropathy includes symptomatic therapy of sensory, motor and autonomic dysfunctions. ⋯ In general, treatment for polyneuropathy should follow a multimodal concept and include the treatment of other symptoms. When choosing pain medication, comorbidities, patient's age and adverse events need to be taken into consideration. Phenotype-based stratification may support specialized pain therapy and achieve the best medical treatment.

Migraine has a very high lifetime prevalence with a severe illness-related burden. As a result, extensive long-term and regular treatment is required, which cannot be covered solely by neurologists. This is particularly the case for the long-term monitoring of migraine, which often takes place over several decades. ⋯ If this therapy is unsuccessful, prophylactic substances must be used that require more specialized knowledge, which is also reflected in the formal prescription requirements. Neurologists and pain therapists should then be involved in the treatment. This is particularly true for the use of Onabotulinumtoxin A and monoclonal CGRP-(receptor)-antibodies.

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.
