Journal ArticleDOI
European federation of neurological societies/peripheral nerve society guideline on the use of skin biopsy in the diagnosis of small fiber neuropathy. report of a joint task force of the european fe-deration of neurological societies and the peripheral nerve society
Giuseppe Lauria,Sung-Tsieh Hsieh,Olle Johansson,William R. Kennedy,Jean-Marc Léger,Svein Ivar Mellgren,Maria Nolano,Ingemar S. J. Merkies,Michael Polydefkis,A. G. Smith,Cornelia Sommer,J. Valls-Solé +11 more
TL;DR: Revision of the guidelines on the use of skin biopsy in the diagnosis of peripheral neuropathy, published in 2005, has become appropriate owing to publication of more relevant articles and most of the new studies focused on small fiber neuropathy (SFN).
Journal ArticleDOI
EFNS guidelines on the use of skin biopsy in the diagnosis of peripheral neuropathy
Giuseppe Lauria,David R. Cornblath,Olle Johansson,Justin C. McArthur,Svein Ivar Mellgren,Maria Nolano,N. Rosenberg,Claudia Sommer +7 more
TL;DR: Punch skin biopsy is a safe and reliable technique andConfocal microscopy may be particularly useful to investigate myelinated nerve fibres, dermal receptors and dermal annex innervation and to assess the potential usefulness of skin biopsies as an outcome measure in peripheral neuropathy trials.

European Federation of Neurological Societies/Peripheral Nerve Society guideline on the use of skin biopsy in the diagnosis of small fiber neuropathy. Report of a joint task force of the European Federation of Neurological Societies and the Peripheral Nerve Society
Guseppe Lauria,Sung-Tsang Hsieh,Olle Johansson,William R. Kennedy,Jean Marc Léger,Svein Ivar Mellgren,Maria Nolano,Ingenar S.J. Merkies,Michael Polydefkis,A. Gordon Smith,Claludia Sommer,J. Valls-Solé +11 more
TL;DR: This revision focuses on the use of skin biopsy with quantification of the linear density of intraepidermal nerve fibers (IENF) to assess small fiber neuropathy (SFN), a subtype of neuropathy for which the diagnosis was first developed through skinBiopsy examination.
Journal ArticleDOI
Intraepidermal nerve fiber density at the distal leg: a worldwide normative reference study
Giuseppe Lauria,Mayienne Bakkers,Christoph Schmitz,Raffaella Lombardi,Paola Penza,Grazia Devigili,A. Gordon Smith,Sung Tsieh Hsieh,Svein Ivar Mellgren,Thirugnanam Umapathi,Dan Ziegler,Catharina G. Faber,Ingemar S. J. Merkies +12 more
TL;DR: A multicenter study to assess the normative values of intraepidermal nerve fiber (IENF) density at distal leg stratified by age deciles found a significant age‐dependent decrease of IENF density in both genders.
Journal ArticleDOI
Outdoor activities and diet in childhood and adolescence relate to MS risk above the Arctic Circle.
Margitta T. Kampman,Margitta T. Kampman,Tom Wilsgaard,Svein Ivar Mellgren,Svein Ivar Mellgren +4 more
TL;DR: Summer outdoor activities in childhood and adolescence are associated with a reduced risk of MS even north of the Arctic Circle, and supplemental cod-liver oil may be protective when sun exposure is less, suggesting that both climate and diet may interact to influence MS risk at a population level.
