MD, Hôpital Pitié Salpêtrière - Assistance Publique Hôpitaux de Paris, Rheumatology department, Pain unit ; 47-83 boulevard de l'hôpital, 75013 Paris, France. Electronic address:

Fibromyalgia and small fibre neuropathy are two diseases leading to chronic widespread pain, and it is difficult to differentiate them in order to provide appropriate care. In this review, we will describe the pathophysiological and clinical differences between fibromyalgia and small fibre neuropathy. In fibromyalgia, pain is increased by dysregulation of central pain processing while small fibre neuropathy pain is related to loss or dysfunction of intraepidermal small nerve fibres. Read More

Department of Neurology, Virginia Commonwealth University, 1101 East Marshall Street, PO Box 980599, Richmond, VA 23298, USA. Electronic address:

This article discusses the chronic immune-mediated polyneuropathies, a broad category of acquired polyneuropathies that encompasses chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), the most common immune-mediated neuropathy, the CIDP variants, and the vasculitic neuropathies. Polyneuropathies associated with rheumatological diseases and systemic inflammatory diseases, such as sarcoidosis, will also be briefly covered. These patients' history, examination, serum studies, and electrodiagnostic studies, as well as histopathological findings in the case of vasculitis, confirm the diagnosis and differentiate them from the more common length-dependent polyneuropathies.

Authors:
Michiaki Koga

Brain Nerve 2020 Aug;72(8):855-862

Department of Neurology and Clinical Neuroscience, Yamaguchi University Graduate School of Medicine.

Sarcoid neuropathy has a broader spectrum of clinical features than previously expected. It is typically characterized by multiple mononeuropathy but often shows a polyneuropathy pattern, making it difficult to be differentiated from other neuropathies. In the diagnostic process, several clinical features, including laterality and proximal-predominance of symptoms at extremities, sensory deficits in the territory of the branch of the peripheral nerve trunk, and positive neuropathic sensory symptoms typically accompanied by pain, could be the cues to evaluate the probability of sarcoid neuropathy.

Ogugua Ndili Obi

Semin Respir Crit Care Med 2020 Oct 24;41(5):716-732. Epub 2020 Jun 24.

Division of Pulmonary, Critical Care and Sleep Medicine, Brody School of Medicine, East Carolina University, Greenville, North Carolina.

Health-related quality of life (HRQoL) describes an individual's perception of the impact of health, disease, and treatment on their quality of life (QoL). It is a reflection of how the manifestation of an illness and its treatment is personally experienced. Assessing HRQoL is particularly important in sarcoidosis because the attributable disease mortality is relatively low, and one of the major reasons for initiating treatment is to improve quality of life.

An Atypical and Multifactorial Acute Immune Polyradiculopathy: A Case Report.

Neurohospitalist 2020 Apr 24;10(2):118-120. Epub 2019 Jul 24.

Department of Neurology, School of Medicine, Washington University in St Louis, St Louis, MO, USA.

Clinical diagnosis often focuses on identifying the single cause of a patient's symptoms but it is becoming increasingly recognized that a subset of patients exist where 2 pathological entities coexist. These patients present a particular diagnostic challenge because the first "positive" diagnostic test is not the definitive stopping point in their evaluation. Here, we present the case of a 47-year-old woman with multiple cranial neuropathies and a polyradiculopathy. Read More
