PURPOSE To determine the prevalence and risk factors for sleep apnea in a keratoconus population. METHODS Ninety-two keratoconus patients and 92 controls were classified as high risk or low risk for sleep apnea, using the Berlin Questionnaire (BQ) or individual history of sleep apnea. Logistic regression was used to investigate the risk factors associated with high risk of sleep apnea in kera...

Objective: To test a prediction model for sleep apnea based on clinical and sociodemographic variables in a population suspected of having sleep disorders and submitted to polysomnography. Methods: We included 323 consecutive patients submitted to polysomnography because of the clinical suspicion of having sleep disorders. We used a questionnaire with sociodemographic questions and the Epworth ...

BACKGROUND Undetected apnea can lead to severe hypoxia, bradycardia, and cardiac arrest. Tracheal sounds entropy has been proved to be a robust method for estimating respiratory flow, thus maybe a more reliable way to detect obstructive and central apnea during sedation. METHODS A secondary analysis of a previous pharmacodynamics study was conducted. Twenty volunteers received propofol and re...

INTRODUCTION Sleep movement disorders includes mainly periodic limb movement and others. The more frequent breathing disorders are: obstructive sleep apnea-hypopnea syndrome and primary snoring. OBJECTIVE To compare sleep architecture in periodic limb movements and breathing disorders of different severity, and weight their interactions. METHODS We compared sleep architecture in 160 patient...

Twenty-six patients with sleep apnea had neuropsychologic testing prior to nocturnal sleep study in a sleep disorders clinic. The cognitive functioning of patients who had sleep apnea with associated hypoxemia was compared to nonhypoxemic patients with sleep apnea. The patients who had sleep apnea with hypoxemia had more severe cognitive impairment than those with sleep apnea without hypoxemia....

OBJECTIVE The aim of this study is to compare patients treated with pharyngoplasty and those treated with palatoplasty for velopharyngeal insufficiency to establish what surgical procedure poses the highest risk for developing sleep apnea. The hypothesis tested in this study is that the incidence of obstructive sleep apnea syndrome associated with pharyngoplasty is greater than that associated ...

OBJECTIVE To determine the prevalence, distribution and determinants of newborn apnea in a resource-constrained setting. DESIGN Retrospective study. MATERIALS AND METHODS Newborn babies who had apnea during hospitalization between January and December 2008 were studied. The sex, age and body weight, clinical conditions, etiologies of apnea and outcome were recorded. Babies with and without ...

we aimed to determine the clinical manifestations of tramadol intoxication in children and to find its potential poor prognostic factors. in a retrospective study, from 1363 cases of admitted pediatric poisoning, all tramadol-exposed hospitalized patients younger than 12 years were included in the study. they were hospitalized between march 2010 and april 2012 to the only referral hospital for ...
