A carotid body tumor is a rare neoplasm, generally benign, that predominantly affects people between their fourth and fifth decades of life. It manifests as a pulsatile and generally painless cervical mass with firm consistency, located below the angle of the jaw. It can progress to the extent that it causes localized pain, dysphagia, hiccups, hoarseness and hypersensitive carotid body syndrome.

Assessment of interobserver concordance in polysomnography scoring of sleep bruxism.

Introduction: Objective evaluation of sleep bruxism (SB) using whole-night polysomnography (PSG) is relevant for diagnostic confirmation. Nevertheless, the PSG electromyogram (EMG) scoring may give rise to controversy, particularly when audiovisual monitoring is not performed. Therefore, the present study assessed the concordance between two independent scorers to visual SB on a PSG performed without audiovisual monitoring.

Orofacial-cervical alterations in individuals with upper airway resistance syndrome.

Introduction: Studies that assess the upper airways in sleep-related breathing disorders have been performed only in patients with obstructive sleep apnea syndrome who seek medical attention. Therefore, in addition to the need for population studies, there are no data on the orofacial-cervical physical examination in subjects with upper airway resistance syndrome.

Objectives: To compare the orofacial-cervical examination between volunteers with upper airway resistance syndrome and without sleep-related breathing disorders.

Temporal sleep patterns in adults using actigraph.

The aim of the present study was to characterize the temporal patterns of sleep and wakefulness in a sample of the adult subjects from São Paulo city. All subjects filled the Morningness/Eveningness Questionnaire (MEQ) and wore an actigraph for at least three consecutive days. A total of 359 subjects were considered for the analyses.

Effects of aging on sleep structure throughout adulthood: a population-based study.

Objective: Although many studies have shown the evolution of sleep parameters across the lifespan, not many have included a representative sample of the general population. The objective of this study was to describe age-related changes in sleep structure, sleep respiratory parameters and periodic limb movements of the adult population of São Paulo.

Methods: We selected a representative sample of the city of São Paulo, Brazil that included both genders and an age range of 20-80 years.

Depressive symptoms and sleep: a population-based polysomnographic study.

The goals of the present study were to determine the prevalence of depression in the adult population of Sao Paulo, Brazil and to explore the relationship among sociodemographic, physical and psychological factors, sleep-related symptoms and polysomnography parameters. Participants of a cross-sectional study (N = 1101) were administered questionnaires and submitted to polysomnography. A score > 20 in the Beck Depression Inventory was used to describe depression.

Consequences of obstructive sleep apnea on metabolic profile: a Population-Based Survey.

Objective: Epidemiologic studies that control for potential confounders are needed to assess the independent associations of obstructive sleep apnea (OSA) with metabolic abnormalities. The aim of our study was to evaluate the associations of OSA with metabolic abnormalities among the adult population of Sao Paulo, Brazil.

Design And Methods: Questionnaires were applied face-to-face, full night polysomnography (PSG) was performed, and blood samples were collected in a population-based survey in Sao Paulo, Brazil, adopting a probabilistic three-stage cluster sample method.

Effect of speech therapy as adjunct treatment to continuous positive airway pressure on the quality of life of patients with obstructive sleep apnea.

Background: Patients with obstructive sleep apnea (OSA) exhibit reduced quality of life (QoL) due to their daytime symptoms that restricted their social activities. The available data for QoL after treatment with continuous positive airway pressure (CPAP) are inconclusive, and few studies have assessed QoL after treatment with speech therapy or other methods that increase the tonus of the upper airway muscles or with a combination of these therapies. The aim of our study was to assess the effect of speech therapy alone or combined with CPAP on QoL in patients with OSA using three different questionnaires.

Methods: In a prospective study carried out among premenopausal women between July and December 2007, a 3-stage cluster sampling was used to ensure accurate representation of the general population of São Paulo, Brazil. Questionnaires were administered, hormonal assays were performed, and full-night polysomnography was recorded.

Adenosine deaminase polymorphism affects sleep EEG spectral power in a large epidemiological sample.

Slow wave oscillations in the electroencephalogram (EEG) during sleep may reflect both sleep need and intensity, which are implied in homeostatic regulation. Adenosine is strongly implicated in sleep homeostasis, and a single nucleotide polymorphism in the adenosine deaminase gene (ADA G22A) has been associated with deeper and more efficient sleep. The present study verified the association between the ADA G22A polymorphism and changes in sleep EEG spectral power (from C3-A2, C4-A1, O1-A2, and O2-A1 derivations) in the Epidemiologic Sleep Study (EPISONO) sample from São Paulo, Brazil.

The association between the Framingham risk score and sleep: a São Paulo epidemiological sleep study.

Background: Sleep is an important factor in the maintenance of cardiovascular integrity. It seems that cardiovascular injury and sleep impairment is another chicken or egg puzzle and we hypothesized that the higher the cardiovascular risk factors the higher the sleep impairment. Therefore, the goal of this study is to analyze the sleep profile of a general population based on cardiovascular risk stratification.
