Small-fibre involvement in diabetic patients with neuropathic foot pain.

Aims: To assess small-fibre involvement in diabetic patients with neuropathic pain.

Methods: Peripheral nerve function was assessed in 30 patients with Type 2 diabetes mellitus (T2DM, n = 24) or impaired glucose tolerance (IGT, n = 6), and clinical symptoms of neuropathic pain in the feet, using nerve conduction studies, autonomic tests, thermal quantitative sensory testing (T-QST) and quantification of intra- and subepidermal nerve fibre densities in skin punch biopsies.

Results: Clinical signs of isolated small-fibre sensory involvement were present in 13 patients [pure small-fibre neuropathy (pSFN)], seven patients had isolated positive sensory symptoms without neurological deficits (pSFN-).

Presymptomatic spondylotic cervical myelopathy: an updated predictive model.

Spondylotic cervical cord compression detected by imaging methods is a prerequisite for the clinical diagnosis of spondylotic cervical myelopathy (SCM). Little is known about the spontaneous course and prognosis of clinically "silent" presymptomatic spondylotic cervical cord compression (P-SCCC). The aim of the present study was to update a previously published model predictive for the development of clinically symptomatic SCM, and to assess the early and late risks of this event in a larger cohort of P-SCCC subjects.
