Abstract
Distal diabetic sensorimotor polyneuropathy (DDSP) is the most prevalent form of diabetic neuropathy, and some of the patients develop gradual pain. Specialized sensory structures present in the skin encode different modalities of somatosensitivity such as temperature, touch, and pain. The cutaneous sensory structures responsible for the qualities of mechanosensitivity (fine touch, vibration) are collectively known as cutaneous mechanoreceptors (Meissner corpuscles, Pacinian corpuscles, and Merkel cell-axonal complexes), which results are altered during diabetes. Here, we used immunohistochemistry to analyze the density, localization within the dermis, arrangement of corpuscular components (axons and Schwann-like cells), and expression of putative mechanoproteins (PIEZO2, ASIC2, and TRPV4) in cutaneous mechanoreceptors of subjects suffering clinically diagnosed non-painful and painful distal diabetic sensorimotor polyneuropathy. The number of Meissner corpuscles, Pacinian corpuscles, and Merkel cells was found to be severely decreased in the non-painful presentation of the disease, and almost disappeared in the painful presentation. Furthermore, there was a marked reduction in the expression of axonal and Schwann-like cell markers (with are characteristics of corpuscular denervation) as well as of all investigated mechanoproteins in the non-painful distal diabetic sensorimotor polyneuropathy, and these were absent in the painful form. Taken together, these alterations might explain, at least partly, the impairment of mechanosensitivity system associated with distal diabetic sensorimotor polyneuropathy. Furthermore, our results support that an increasing severity of DDSP may increase the risk of developing painful neuropathic symptoms. However, why the absence of cutaneous mechanoreceptors is associated with pain remains to be elucidated.

Abstract
Polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes (POEMS) syndrome is a rare systemic disorder linked to plasma cell dyscrasia and is related to elevation of vascular endothelial growth factor (VEGF). Diagnosis is still challenging and pathophysiology unclear. Because VEGF drives neovascularization, we investigated skin and nerve vascularization in 6 patients with POEMS syndrome compared with 5 control groups of polyneuropathies and healthy subjects (n = 104) from the University Hospital of Limoges between 2009 and 2018. We evaluated loss of small and large fibers in these patients. Skin and nerve vascularization were quantified manually on immunofluorescence using vessel staining (anti-α-SMA antibody). Dermal vascularization was significantly higher in POEMS syndrome than in other groups, but unrelated to loss of small fibers and VEGF. Perineurial vascularization was higher in POEMS syndrome than in healthy controls, and was related to loss of large fibers and VEGF level. Our study highlights the existence of neovascularization in skin of patients with this rare disorder. These data suggest that skin neovascularization could be an additional biomarker to help in the diagnosis and understanding of POEMS syndrome. Moreover, nerve neovascularization, driven by VEGF overexpression, may play a role in the pathophysiology of large fiber loss in this condition.

Abstract
OBJECTIVE Small-fiber sensory and autonomic symptoms are early presentations of familial amyloid polyneuropathy (FAP) with transthyretin (TTR) mutations. This study aimed to explore the potential of skin nerve pathologies as early and disease-progression biomarkers and their relationship with skin amyloid deposits. METHODS Skin biopsies were performed in patients and carriers to measure intraepidermal nerve fiber (IENF) density, sweat gland innervation index of structural protein gene product 9.5 (SGII[PGP9.5]) and peptidergic vasoactive intestinal peptide (SGII[VIP]), and cutaneous amyloid index. These skin pathologies were analyzed with clinical disability assessed by FAP stage score (stage 0-4) and compared to neurophysiological and psychophysical tests. RESULTS There were 70 TTR-mutant subjects (22 carriers and 48 patients), and 66 cases were TTR-A97S. Skin nerve pathologies were distinct according to stage. In carriers, both skin denervation and peptidergic sudomotor denervation were evident: (1) IENF density was gradually reduced from stage 0 through 4, and (2) SGII(VIP) was markedly reduced from stage 1 to 2. In contrast, SGII(PGP9.5) was similar between carriers and controls, but it declined in patients from stage 2. Skin amyloids were absent in carriers and became detectable from stage 1. Cutaneous amyloid index was correlated with SGII(PGP9.5) and stage in a multivariate mixed-effect model. When all tests were compared, only IENF density, SGII(PGP9.5), and cutaneous amyloid index were correlated with stage, and IENF density had the highest abnormal rate in carriers. INTERPRETATION Biomarkers of sensory and sudomotor innervation exhibited a stage-dependent progression pattern, with sensory nerve degeneration as the early skin nerve pathology. Ann Neurol 2019;85:560-573.

Abstract
OBJECTIVE Thermal block of action potential conduction using infrared lasers is a new modality for manipulating neural activity. It could be used for analysis of the nervous system and for therapeutic applications. We sought to understand the mechanisms of thermal block. APPROACH To analyze the mechanisms of thermal block, we studied both the original Hodgkin/Huxley model, and a version modified to more accurately match experimental data on thermal responses in the squid giant axon. MAIN RESULTS Both the original and modified models suggested that thermal block, especially at higher temperatures, is primarily due to a depolarization-activated hyperpolarization as increased temperature leads to faster activation of voltage-gated potassium ion channels. The minimum length needed to block an axon scaled with the square root of the axon's diameter. SIGNIFICANCE The results suggest that voltage-dependent potassium ion channels play a major role in thermal block, and that relatively short lengths of axon could be thermally manipulated to selectively block fine, unmyelinated axons, such as C fibers, that carry pain and other sensory information.

Abstract
OBJECTIVE To examine intraepidermal nerve fibre densities (IENFDs) in patients with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin change (POEMS) syndrome. METHODS The IENFDs of 11 patients with POEMS syndrome were estimated. We determined whether IENFD was associated with patient clinical features or the estimated number of nerve fibres on complete cross-sections of biopsied sural nerves. RESULTS IENFD was significantly reduced (9.7±4.4fibres/mm) compared with normal controls (p<0.05), although the individual values varied from 1.4 to 14.4fibres/mm. The presence of glucose intolerance was significantly associated with a reduction of IENFD (p<0.05). The number of unmyelinated fibres was preserved at the sural nerve level and was not correlated with IENFD. In contrast, the number of myelinated fibres was correlated with IENFD (p<0.05). CONCLUSIONS Some of the patients presented with a severe IENFD reduction. Because the number of unmyelinated fibres was well preserved at the level of the sural nerve biopsy, this severe reduction may indicate involvement at the most distal nerve terminals of unmyelinated fibres. Although the reduction of IENFD becomes evident as polyneuropathy becomes severe, the effects of glucose intolerance should also be considered in patients with moderate to severe reductions.
