Improving the performance of peripheral arterial tonometry-based testing for the diagnosis of obstructive sleep apnea.

Outside sleep laboratory settings, peripheral arterial tonometry (PAT, eg, WatchPat) represents a validated modality for diagnosing obstructive sleep apnea (OSA). We have shown before that the accuracy of home sleep apnea testing by WatchPat 200 devices in diagnosing OSA is suboptimal (50%-70%). In order to improve its diagnostic performance, we built several models that predict the main functional parameter of polysomnography (PSG), Apnea Hypopnea Index (AHI).

Performance of peripheral arterial tonometry-based testing for the diagnosis of obstructive sleep apnea in a large sleep clinic cohort.

Study Objectives: Peripheral arterial tonometry (PAT)-based technology represents a validated portable monitoring modality for the diagnosis of OSA. We assessed the diagnostic accuracy of PAT-based technology in a large point-of-care cohort of patients studied with concurrent polysomnography (PSG).

Methods: During study enrollment, all participants suspected to have OSA and tested by in-laboratory PSG underwent concurrent PAT device recordings.

Sleep telemedicine training in fellowship programs: a survey of program directors.

Study Objectives: Telemedicine is a novel modality of health care delivery that can improve patients' access to sleep medicine services, but little is known about telemedicine training during sleep medicine fellowship. We studied telemedicine training prevalence, use, and attitudes of program directors (PDs) and other faculty members, PDs' receptiveness to a standardized telemedicine curriculum, and whether PDs have reviewed existing American Academy of Sleep Medicine (AASM) sleep telemedicine reference materials.

Methods: This was an anonymous online survey of all 86 PDs of accredited sleep medicine fellowships in the United States.

Opinion survey of health care providers towards psychogenic non epileptic seizures.

Objectives: Psychogenic non epileptic seizures (PNES) are challenging conditions to diagnose and manage. Previous workers have investigated the opinion of health care providers towards PNES; still several lacunae remain to be stressed. Amongst health care professionals, opinion of nurses has not been adequately explored.

Psychogenic non-epileptic seizures: a challenging entity.

Psychogenic non-epileptic seizures (PNES) are commonly encountered in neurologic practice. They are often misdiagnosed as epileptic seizures and treated as such for several years before a correct diagnosis is established. Such a misdiagnosis has the potential to expose patients to undue risk through several anti-epileptic drugs (AEDs).
