The pathophysiological basis of obstructive sleep apnea (OSA) is not completely understood and likely varies among patients. In this regard, some patients with OSA do not exhibit hypoxemia. We aimed to analyze the clinical, sleep, and autonomic features of a group of patients with severe OSA without hypoxia (OSA-h) and compare to OSA patients with hypoxia (OSA+h) and controls. ⋯ OSA is a heterogeneous entity. These differences must be taken into account in future studies when analyzing therapeutic approaches for sleep apnea patients.

The aim of this study was to identify neurophysiologic markers generated by primary motor and premotor cortex for laryngeal muscles, recorded from laryngeal muscle. ⋯ Described methodology can be used in preoperative mapping, and it is expected to facilitate surgical planning and intraoperative mapping, preserving these areas from injuries.

Review Meta Analysis
Does anodal transcranial direct current stimulation modulate sensory perception and pain? A meta-analysis study.
The primary aim of this systematic review was to evaluate the effects of anodal transcranial direct current stimulation (a-tDCS) on sensory (STh) and pain thresholds (PTh) in healthy individuals and pain levels (PL) in patients with chronic pain. ⋯ Site of stimulation should have a differential effect over pain relief.

Focal nerve enlargement is a characteristic finding in chronic inflammatory demyelinating polyneuropathy (CIDP). We performed this study to assess the distribution of nerve enlargement through ultrasonographic examination of peripheral nerves and to correlate the ultrasonographic findings with clinical features. ⋯ Pattern analysis of nerve enlargement using ultrasonography is a supportive tool in the diagnosis of CIDP.

To investigate whether intraepidermal electrical stimulation (IES) can evaluate nociceptive Aδ- and C-fiber dysfunctions of an experimental model of small-fiber neuropathy (SFN) with transdermal lidocaine. ⋯ IES has advantages in terms of cost, convenience, and invasiveness. It may have potential for a clinical tool to elucidate the pathophysiology of patients with SFN, including the differences between Aδ and C fibers.
