BACKGROUND--Ultrasound allows observation of the thickness diaphragm in zone apposition vivo during relaxation and maximum inspiratory efforts. METHODS--Changes were studied by B mode (two dimensional) ultrasound 13 healthy men aged 29-54 years seated position. A high resolution 7.5 MHz transducer was held perpendicular to chest wall line a right intercostal space between anteroaxillary mid-axillary lines observe 0.5-2 cm below costophrenic angle. The changes observed while breath holding at...

To investigate the presence of restless legs syndrome (RLS) and quality sleep in a population type 2 diabetic patients.The study was composed 100 consecutive patients regularly attending diabetes clinic at University Hospital Federal Ceará. The subjects' assessed by Pittsburgh Sleep Quality Index, excessive daytime sleepiness (EDS) measured Epworth Sleepiness Scale. RLS diagnosed using four minimum criteria defined International Restless Legs Syndrome Study Group. Other relevant clinical...

There is little information on the morphometric characteristics of diaphragm in patients with Duchenne muscular dystrophy.The thickness was measured at zone apposition using B mode ultrasonography 10 boys dystrophy mean (SD) age 10.3 (1.3) years and 12 normal controls 11.3 (2.0) during relaxation (DiTrelax) maximum effort inspiratory manoeuvres (DiTPimax) functional residual capacity.DiTrelax greater (1.74 (0.21) mm) than (1.48 (0.20) mm), difference (95% CI) 0.26 (0.08 to 0.44), despite...

We have tested the hypothesis that restless leg syndrome (RLS) is related to quality of sleep, fatigue and clinical disability in multiple sclerosis (MS). The diagnosis RLS used four minimum criteria defined by International Restless Legs Syndrome Study Group. Fatigue was assessed Severity Scale (FSS >27), sleep Pittsburgh Sleep Quality Index (PSQI >6), excessive daytime sleepiness Epworth Sleepiness (ESS >10) Expanded Disability Status (EDSS). Forty-four patients (32 women) aged 14 64 years...

Truck drivers are more likely to suffer severe injury and death due certain truck driving characteristics. Identifying preventing factors associated with accidents in this population is important minimize damage improve road safety. Excessive daytime sleepiness a major public health problem, leading impaired cognitive function, reduced alertness, increased risk of motor vehicle crashes. The aim cross-sectional study was determine the prevalence predictors hypersomnolence (defined as an...

Chronic obstructive pulmonary disease (COPD), a major cause of death and disability, is attributed to an abnormal inflammatory response by the lungs noxious substances, primarily from cigarette smoke. Although oxidative stress regarded as central pathogenesis COPD, very few studies have examined effects antioxidants in this condition. This was randomized, double-blind, placebo-controlled study on melatonin COPD. Thirty-six consecutive patients with clinically stable moderate severe COPD (30...

Medical students are at higher risk for depression, affecting not only their lives but also patient care. This article studied a population of medical engaged in lecture-based learning regarding the presence depressive symptoms and its relation to morningness-eveningness. Depressive were assessed by Beck Inventory scale (BDI>10), diurnal preference was Horne & Ostberg Morningness/Eveningness Questionnaire (MEQ). Family history depression involvement regular physical activity investigated. A...

There have been few studies of respiratory and limb muscle size function in middle-aged patients with asthma persistent airways obstruction. We compared the forces generated by thigh muscles their dimensions assessed ultrasound nine chronic (mean age 56 (SD 8) yrs; functional residual capacity/total lung capacity ratio (FRC/TLC) 60 (10)%), normal subjects (aged 53 (7) FRC/TLC 55 (5)%). Diaphragm thickness was measured at zone apposition B-mode during relaxation (DiTrelax) a maximum-effort...

To investigate how treatment can affect airway dynamics and respiratory muscle strength in Parkinson's disease (PD), we assessed maximum effort inspiratory expiratory mouth pressures (MIP MEP), oscillatory impedance, flow-volume curves (MEFV MIFV) 10 patients (8 male 2 female; mean age 51 ± 5.3 yr, SD) after temporary interruption of antiparkinsonian therapy (off) during continuous subcutaneous infusion a direct stimulant dopamine receptors, apomorphine (on). Treatment improved neurologic...

OBJECTIVES: Subjective sleep complaints have been reported in up to 80% of patients with end stage renal disease (ESRD). In these patients, disturbances manifesting as insomnia, apnea syndrome, restless leg syndrome (RLS), periodic limb movement disorder and excessive daytime sleepiness (EDS) frequently reported. Moreover, studies about the role dialysis shift on abnormalities, morbidity mortality are still scarce. The aim this study was investigate influence quality abnormalities ESRD....

Disturbed sleep is common in chronic obstructive pulmonary disease (COPD). Conventional hypnotics worsen nocturnal hypoxemia and, severe cases, can lead to respiratory failure. Exogenous melatonin has somnogenic properties normal subjects and improve several clinical conditions. This randomized, double-blind, placebo-controlled study was carried out determine the effects of on COPD. Thirty consecutive patients with moderate very COPD were initially recruited for study. None participants had...
