Clinical evaluation criteria for the assessment of impaired pain sensitivity by thulium-laser evoked potentials
2000
Abstract Objectives : Cortical potentials evoked by carbon dioxide laser pulses have been applied in clinical practice to study nociceptive pathways for several years. In this study, we evaluate the properties of an infrared laser (thulium-YAG) with a penetration depth in the skin that matches the intracutaneous depth of nociceptors. Methods : Temperature measurements and modelling showed that the thulium laser generates painful intracutaneous temperatures with less surface heating than the carbon dioxide laser and with no side effects (up to 600 mJ pulse energy). To develop clinical evaluation criteria, laser-evoked potentials (LEPs) were recorded from 3 midline positions (Fz, Cz, Pz) vers…
Genetics of the Charcot-Marie-Tooth disease in the Spanish Gypsy population: the hereditary motor and sensory neuropathy-Russe in depth
2012
Four private mutations responsible for three forms demyelinating of Charcot-Marie-Tooth (CMT) or hereditary motor and sensory neuropathy (HMSN) have been associated with the Gypsy population: the NDRG1 p.R148X in CMT type 4D (CMT4D/HMSN-Lom); p.C737_P738delinsX and p.R1109X mutations in the SH3TC2 gene (CMT4C); and a G>C change in a novel alternative untranslated exon in the HK1 gene causative of CMT4G (CMT4G/HMSN-Russe). Here we address the findings of a genetic study of 29 Gypsy Spanish families with autosomal recessive demyelinating CMT. The most frequent form is CMT4C (57.14%), followed by HMSN-Russe (25%) and HMSN-Lom (17.86%). The relevant frequency of HMSN-Russe has allowed us to inv…
Dual sensory loss and social participation in older Europeans
2013
The purpose of the study was to describe the prevalence of hearing difficulties, vision difficulties and dual sensory difficulties in 11 European countries, and to study whether sensory difficulties are associated with social inactivity in older Europeans. This cross-sectional study is based on the 2004 data collection of the Survey of Health, Ageing and Retirement in Europe comprising 27,536 men and women aged 50 years and older. Hearing and vision difficulties, as well as participation in seven different social activities were assessed using a structured computer-assisted personal interview. Logistic regression models were used for analyses. Altogether, 5.9 % of the participants reported …
Nasal tactile sensitivity in elderly
2010
Conclusion: Although older people varied widely in tactile sensitivity, our results show that tactile thresholds increased with age. Objectives: The aim of this study was to evaluate the effects of aging on nasal tactile sensitivity. Methods: A total of 160 healthy patients aged between 50 and 90 years were included. According to their age, patients were divided into groups (A, B, C, D, E, F, G, and H). From the age of 50, each group included subjects with an age range of 5 years (i.e. group A, 50-55 years; group B, 56-60 years, etc.). Each patient's outcome was assessed through the nasal monofilament test: a set of 20 Semmes-Weinstein monofilaments was used to detect nasal sensitivity for …
