RESUMO
BACKGROUND AND AIMS: Diabetic sensorimotor polyneuropathy (DSP) is a common complication of diabetes. The Toronto Clinical Neuropathy Score (TCNS) is a useful tool for detecting DSP. However, it is not available in Spanish. The study aimed to translate and culturally adapt the TCNS and modified (mTCNS) scales into Spanish and evaluate their measurement properties. METHODS: A multistep forward-backward method was used for translation and cultural adaptation. A panel of physicians subjected the final Spanish versions of TCNS and mTCNS (TCÑS, mTCÑS) to cognitive debriefing. Consecutive patients with diabetes mellitus and DSP were recruited from an outpatient clinic, and the TCÑS and mTCÑS were tested for construct validity, along with other measures. RESULTS: The internal consistency of both TCÑS and mTCÑS was excellent, as evidenced by Cronbach's Alpha coefficients of 0.83 and 0.85, respectively. Furthermore, there was a robust positive correlation between TCÑS and mTCÑS. In addition, TCÑS was found to exhibit a strong negative correlation with sural sensory nerve action potential amplitude (r = -0.9206) and peroneal compound motor action potential amplitude (r = -0.729), while demonstrating a positive and strong correlation with the Michigan Neuropathy Screening Instrument (r = 0.713). INTERPRETATION: The TCÑS and mTCÑS are reliable and valid translations of the original TCNS. The TCÑS and mTCÑS can be used to diagnose and measure the severity of neuropathy in Spanish-speaking patients with diabetes.

Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of acquired immune-mediated diseases, which typically involve the striated muscle with a variable involvement of the skin and other organs. Clinically, they are characterized by proximal muscle weakness, elevation of muscle enzymes, myopathic changes on electromyography and an abnormal muscle biopsy. The different IIM have been classified according to their distinctive histopathologic features in dermatomyositis (DM), polymyositis (PM), inclusion body myositis (IBM) and immune-mediated necrotizing myopathy (IMNM). Several myositis-specific antibodies are associated with the different phenotypes, as well as with different risk of neoplastic disease and systemic complications. The basis for the treatment of DM, PM, and IMNM is immunosuppression. For IBM there are only symptomatic treatments. Steroids, associated or not with other immunosuppressant drugs, are the first line of treatment. Biologic drugs will allow future individualized therapies. The 10-year survival of DM, PM and IMNM is 62 to 90%. The leading causes of death are neoplastic, lung and cardiac complications. IBM does not impair survival, although it affects the quality of life.

Background: Carpal tunnel syndrome (CTS) represents 90% of entrapment neuropathies. Severity may be greater in older patients. Aim: To describe the electrophysiological findings in adult patients with CTS and determine if severity is related to age. Material and Methods: Descriptive and retrospective study of electrophysiological findings in patients over 18 years of age with clinical suspicion of CTS, studied between January 2011 and December 2015. Neurophysiological severity was classified in 3 grades, comparing them by age, gender and laterality. Results: Of 1156 patients subjected to electrophysiological studies due to a clinical suspicion of CTS, 690 (60%) had electrophysiological features of the disease. In 274 patients (24%) the compromise was mild, in 162 (14%) it was moderate and in 254 (22%) it was severe. There was a positive association between age and CTS severity (p < 0.01). Severity was significantly greater in males than females (p < 0.01). Bilateral CTS was present in 471 patients (68%), which was associated with increased age and severity (p < 0.01). Conclusions: Electrophysiological severity in CTS increases with age. Other factors associated with higher severity are male gender and bilateral disease.
