PURPOSE To explore the prevalence of normal tension glaucoma (NTG) among patients with obstructive sleep apnea syndrome (OSAS) and to examine OSAS as a risk factor of NTG. PATIENTS AND METHODS Fifty-one consecutive white patients with OSAS were compared with 40 healthy subjects. All the study subjects underwent blood gas analysis, polysomnography,(More)
OBJECTIVE In the dynamic organization of sleep, cyclic alternating pattern (CAP) expresses a condition of instability of the level of vigilance that manifests the brain's fatigue in preserving and regulating the macrostructure of sleep. We evaluated the presence of CAP in patients with fibromyalgia (FM) compared to healthy controls. METHODS Forty-five(More)
STUDY OBJECTIVE Childhood exposure to environmental tobacco smoke (ETS) adversely affects dynamic spirometric indexes as a result of combined early life (including in utero) and current exposure to parental smoking. The aim of our study was to investigate the effect of ETS on lung function and to identify the most sensitive functional parameter for(More)
OBJECTIVE In this study, we would like to show that anterior rhinometry measurement of nasal resistance would be a simple and useful test to identify severe obstructive sleep apnea (OSA) in a population of children affected by adenotonsillar hypertrophy. METHODS Seventy-three consecutive children (44 males; mean age 5.4+/-1.2 years) with adenotonsillar(More)
Chronic pain in fibromyalgia patients, together with its associated symptoms and co-morbidities, is now considered a result of dysregulated mechanisms in the central nervous system (CNS). As fibromyalgia patients often report sleep problems, the physiological processes that normally regulate sleep may be disturbed and overlap with other CNS dysfunctions.(More)
Obesity induces multiple physiologic changes at the respiratory and circulatory systems level. A study was developed to identify symptoms and signs able to discriminate subjects at high risk of obstructive sleep apnea (OSA) and to evaluate the presence of OSA in a population of obese patients referred to the Clinical Nutrition Service of the Luigi Sacco(More)
BACKGROUND Increased energy expenditure (EE) has been reported in patients with obstructive sleep apnea (OSA). It has been postulated that CPAP treatment may induce weight reduction in obese patients, even if it has not been confirmed by recent studies. In the present study we investigated the effect of OSA on EE and the effect of CPAP on body weight and(More)
OBJECTIVES To analyze the influence of a home care (HC) program on outcomes of patients with chronic obstructive pulmonary disease (COPD) receiving long-term oxygen therapy (LTOT) in comparison with outcomes of patients receiving standard care (SC). DESIGN A 10-year follow-up study with 2 parallel cohorts (HC vs SC). SETTING University hospital. (More)
BACKGROUND Nocturnal oxygen desaturations (NOD), especially during REM sleep, have been described in patients with COPD. However, the role of NOD in the evolution of COPD to chronic respiratory failure has not been well studied. OBJECTIVE The aim of our study was to evaluate whether NOD is a risk factor for the development of chronic respiratory failure(More)
We assessed the presence of lung dysfunction in children with type 1 diabetes, evaluated as reduced diffusing capacity of the lung for carbon monoxide (DLCO), and its components: membrane diffusing capacity (DM) and pulmonary capillary blood volume (Vc). A total of 42 children, aged 15.6 ± 3.8 years, with type 1 diabetes for 8.3 ± 5.5 years, and 30 healthy(More)
