STUDY OBJECTIVES It has been suggested that sleep-disordered breathing (SDB) is a risk factor for ischemic heart disease, and may be associated with increased morbidity and mortality due to cardiovascular disease. The aim of this study was to examine the relation between nocturnal oxygen desaturation (NOD) due to SDB and the Gensini score, which is given to define the severity of coronary ather...

Pulse oximetry is useful for screening sleep apnoea syndrome in dialysis patients Sir, Sleep apnoea syndrome (SAS) is characterized by repetitive nocturnal hypoxia, while it is also known to be a risk factor for cardiovascular disease [1]. The prevalence of SAS in dialysis patients has been shown to range from 20 to 50% in comparison to a range of 2–4% in the general population [2,3]. Although ...

BACKGROUND CONTEXT The nerve root sedimentation sign in transverse magnetic resonance imaging has been shown to discriminate well between selected patients with and without lumbar spinal stenosis (LSS), but the performance of this new test, when used in a broader patient population, is not yet known. PURPOSE To evaluate the clinical performance of the nerve root sedimentation sign in detectin...

Introduction When obstructive sleep apnoea (OSA) does not occur throughout sleep, there must be factors influencing its presence or absence. These are most likely to be sleep stage, posture and presleep alcohol, among others. We hypothesised that as OSA severity increases, the likelihood of postural OSA (POSA) would also decrease. Methods Laboratory sleep studies of 39 patients with OSA were ...

The authors identified patients with an increase in their Oswestry Disability Index (ODI) score after lumbar spine fusion to evaluate whether this is a plausible definition of deterioration and to determine whether any common patient characteristics exist.A total of 1054 patients who underwent lumbar spinal fusion and had 2-year follow-up data, including the Short Form 36, the ODI, and numeric ...

STUDY DESIGN Translation, revision, back-translation, and 3-way validity were performed. OBJECTIVE The objective of this study was to translate a version of the Oswestry Disability Index (ODI) into Brazilian Portuguese and evaluate its reliability. SUMMARY OF BACKGROUND DATA Reports in the literature have identified a need for internationally standardized and reliable measurements to analyz...

Diffusion tensor imaging (DTI) has been widely used to visualize peripheral nerves, but the microstructure of compressed nerve roots can be assessed using DTI. However, there are no data regarding the association among microstructural changes evaluated using DTI, the symptoms assessed using the Oswestry Disability Index (ODI) and the duration of symptoms after surgery in patients with lumbar di...

Study Design Retrospective reliability and validity study. Objective To validate a recently translated Russian language version of the Oswestry Disability Index (R-ODI) using standardized methods detailed from previous validations in other languages. Methods We included all subjects who were seen in our spine surgery clinic, over the age of 18, and fluent in the Russian language. R-ODI was tran...

PURPOSE We describe the influence of vagus nerve stimulation (VNS) with standard mode and rapid cycling mode on sleep related breathing in two patients with epilepsy. METHODS Two VNS treated patients underwent digital video-polysomnography for three nights (night 1: rapid cycling mode; night 2: standard mode; night 3: off mode). RESULTS In patient 1, on off mode, apnea-hypopnea index (AHI) ...
