background and objective: failure in diagnosis and treatment of sleep apnea in children lead to physical and mental growth retardation, cardiopulmonary, and/or behavioral disorders. this study was aimed to evaluate polysomnographic (psg) and clinical findings of sleep apnea in children referred to a sleep clinic in qazvin, iran. materials and methods: this cross-sectional study was conducted am...

BACKGROUND Heart rate turbulence (HRT) assessment is used as noninvasive method based on physiological sinus node response to the premature ventricular beat. Blunted HRT may indicate the autonomic nervous system impairment and can be helpful in identifying high-risk patients. Obstructive sleep apnea syndrome (OSAS) leads to cardiovascular complications. Autonomic nervous system and baroreflex d...

Last week we publiihed an essay on snoring, its causes, varying degrees of severity, and the types of remedies people have sought. I observed that there is very little literature in scientific and medical journals on snoring and that, untif recently, it was not treated as a medlcsf problem at all. 1 However, this picture is beginning to change due to the recent interest in a breathing disorder ...

Background Systemic carnitine deficiency may present with apnea, hypotonia, and poor growth. Premature infants often manifest these symptoms and are at risk of developing carnitine deficiency because of immaturity of the biosynthetic pathway, lack of sufficient predelivery transplacental transport, and lack of sufficient exogenous supplementation. Objective This study was undertaken to examine ...

background and objective: obstructive sleep apnea (osa) is a disease with serious consequences. many portable devices have been developed to overwhelm some of limitations in the accessibility of the gold standard test for osa, polysomnography (psg). this study aimed to determine diagnostic accuracy of a portable sleep apnea screener against psg in patients of a sleep clinic. materials and metho...
