[Value of the cutaneous-plantar reflex in the diagnosis of idiopathic carpal tunnel syndrome].

Introduction: Carpal tunnel syndrome (CTS) is the most common of all focal neuropathies. Its diagnosis is based on a neurophysiological study of the thick motor and sensory fibres in patients with a characteristic clinical picture, although sometimes, in mild cases, this study does not detect the abnormalities. The decision was made to evaluate the small-calibre sympathetic fibres by means of cutaneous-plantar reflex (CPR) in patients with different degrees of idiopathic CTS.

[Predictive capacity of 3 methods for estimating the maintenance dose of digoxin in elderly patients].

Purpose: To evaluate three methods for digoxin dose adjustment in aged patients.

Methods: We determined the plasma digoxin levels that would be attained in 47 consecutive old patients with doses adjusted to the creatinin clearance (Clc) by means of three mathematical functions.

Results: Age: 79.

[The most significative parameters for the diagnosis of focal neuropathy of the cubital nerve in the elbow].

Objective: Determine the diagnostic validity of the most usual neurophysiological procedures in the examination of compressive neuropathies and/or ulnar nerve entrapment at the elbow.

Patients And Methods: A prospective observational study was carried out over a period of one year which included 19 patients with clinical features compatible with entrapment/compression of the ulnar nerve at the elbow, their neurophysiological diagnosis and surgical confirmation. We also studied 49 patients who were attended in our clinic for other reasons not related to disorders of the ulnar nerve.
