Small fibre dysfunction, microvascular complications and glycaemic control in type 1 diabetes: a case–control study

2011

Aims/hypothesis The aim of this study was to determine the influence of microvascular disease on C-fibre function in patients with type 1 diabetes of moderate duration. Methods The axon-reflex flare area induced on the dorsum of the foot by local skin heating to 47°C was measured with a laser Doppler imager (LDI) in sex-, age-and heightmatched groups with type 1 diabetes, with and without microvascular disease (MV+ and MV−, respectively) and in healthy controls (HC). Each group consisted of 24 individuals and all were free from clinical neuropathy (neuropathy disability score <3 and Toronto clinical neuropathy score <5

“…The objectivity of the method of measuring sensitivity has been questioned by Freeman et al, who proposed that subjects can deceive the examiner [44]. On the other hand, Chong and Cros concluded that the reliability is highly dependent on accurate use of methodology [23]. In the current study, the first and last measurement of each trial was made at the same frequency (32 Hz) to test the accuracy.…”

“…To evaluate sensibility, quantitative sensory testing (QST) has frequently been used in different clinical, epidemiologic, and research studies [23]. There are various QST methods, such as a simple patient answer of yes or no whether stimuli could be identified [24], choice between one out of two time periods that include stimuli [25], or when the patient is asked to press a button when a vibration stimuli is perceived and to press again when the stimulus disappears (the method of limits) [26].…”

Abstract-This study investigated detection thresholds of vibrometric stimuli in patients with transfemoral amputation supplied with osseointegrated (OI) and socket-suspended prostheses. It included 17 patients tested preoperatively with socket-suspended prostheses and after 2 yr with OI prostheses and a control group (n = 17) using socket-suspended prostheses, evaluated once. Assessments on the prosthetic and intact feet were conducted at six frequencies (8,16,32, 64, 125, and 250 Hz). Furthermore, measurements were conducted to investigate how vibrometric signals are transmitted through a test prosthesis. The results showed that the OI group had improved ability to detect vibrations through the prosthesis at 125 Hz (p = 0.01) at follow-up compared with the preoperative measurement. Compared with the control group, the OI group at follow-up had better ability to detect high frequency vibrations through the prosthesis (125 Hz, p = 0.02; 250 Hz, p = 0.03). The vibrometric signal transmitted through the test prosthesis was reduced at 8, 125, and 250 Hz but was amplified at 16, 32, and 64 Hz. Differences between the OI and the control groups were found in the highest frequencies in which the test prosthesis showed reduction of the vibrometric signal. The study provides insight into the mechanisms of vibration transmission between the exterior and bone-anchored as well as socketsuspended amputation prostheses.

“…In the past few decades, more than 15 different methodological approaches to QST have been developed 207,211,212 , thereby limiting the possibility of a standardized assessment. The International Association for the Study of Pain has provided consensus criteria on use and interpretation of QST findings 213 , emphasizing that a standardized protocol, adequate equipment, trained personnel and use of standard reference values should be developed.…”

New technologies for the assessment of neuropathies

et al. 2017

Peripheral neuropathies are among the most common neurological disorders 1 . In routine clinical practice, diagnosis of peripheral neuropathies is typically based on clinical assessment, nerve conduction studies and needle electromyography, which can determine whether symptoms are caused by primary axonal damage or demyelinating damage. This distinction is often relevant to therapeutic choices and to prognosis, as axonal damage typically reflects an inflammatory (for example, vasculitic) or degenerative (for example, hereditary or idiopathic) process that correlates with disability, whereas demyelinating damage can reflect a hereditary neuro pathy, but more often reflects an acquired immunemediated neuropathy. Besides metabolic, inflammatory or primary degenerative neuropathies, peripheral nerves can also be damaged by compression from adjacent tissue structures, such as tendons, cysts or haematomas. In this case, proper identification of the site, nature and degree of the lesion might be challenging, but is relevant to treatment and prognosis. Moreover, some patients present with symptoms that suggest damage to small nerve fibres, which nerve conduction studies cannot be used to detect.In the past 15 years, several techniques have become available to investigate focal and diffuse peripheral neuropathies, and their reliability has widened the spectrum of diagnostic tools for clinicians and improved assessment of neuropathies. In this Review, we provide an overview of these new and emerging technologies. We first discuss peripheral nerve imaging with MRI and ultrasonography, which can provide information about the precise localization of neuro pathies and the pathological processes involved in large-fibre neuropathies, and can complement clinical and electrophysiological evaluation. We then consider techniques that can provide diagnostic information when the pathological process is restricted to small nerve fibres and is consequently not detectable with nerve conduction studies or neuroimaging. These include skin biopsy, which is established in clinical practice, and the emerging techniques of corneal confocal microscopy, laser-evoked potentials and heat-related and pain-related evoked potentials, and microneurography.Nerve imaging technology Advances in imaging techniques have made it possible to gain great insight into nerve pathology with magnetic resonance and ultrasound. Each approach offers distinct advantages, and can provide different information about damage to large myelinated fibres. Abstract | Technical advances are rapidly changing the clinical and instrumental approach to peripheral nerve diseases. Magnetic resonance neurography, diffusion tensor imaging and nerve ultrasonography are increasingly entering the diagnostic workup of peripheral neuropathies as tools that complement neurophysiology and enable investigation of proximal structures, such as plexuses and roots. Progress in the design of magnetic resonance scanners and sequences, and the development of high-frequency ultrasound probes mean th...
