This study examined the effects of aerobic exercise on lipid levels in premenopausal and postmenopausal women. Fifty healthy middle-aged women (mean age, 50 years) were randomly assigned to 12 weeks of either aerobic exercise (walking and jogging) or nonaerobic strength exercise (circuit Nautilus training). Concentrations of total cholesterol, high density(More)
Examined the influence of ovarian function on psychophysiological stress responses and determined if aerobic exercise reduced stress reactivity. Fifty premenopausal and postmenopausal women initially were subjected to a public speaking task and an ice-on-the-forehead procedure, during which time their blood pressure and heart rate were monitored and(More)
In this study, we examined the relation between serum lipid levels, gender, and cardiovascular and neuroendocrine stress reactivity in patients with mild hypertension. Ninety-nine individuals (62 men, 37 women) with mild hypertension performed four mental stress tasks: mental arithmetic, public speaking, cold stress, and a computer videogame. Cardiovascular(More)
Respiratory tract infection is a major cause of hospitalization in children. Although most such infections are viral in origin, it is difficult to differentiate bacterial and viral infections, as the clinical symptoms are similar. Multiplex polymerase chain reaction (PCR) methods allow testing for multiple pathogens simultaneously and are, therefore,(More)
BACKGROUND Acute gastroenteritis remains a common condition among infants and children throughout the world. In 1996, The American Academy of Pediatrics (AAP) revised its recommendations for the treatment of infants and children with acute gastroenteritis. AIM The purpose of this survey was to determine how closely current treatment among Lebanese(More)
Recent modifications of pre existing Beta 2 drugs and new substances with a prolonged bronchodilator effect may improve asthmatic treatment, in term of duration of benefit and compliance to medication. Evaluation of bronchodilation is still debated. When single dose of drug is administered, nycthemeral rhythm, baseline pulmonary function are to be taken in(More)
Congenital auriculo-ventricular blocks (CAVB) are usually linked to maternal auto-immune diseases and their management remains controversial. We report three cases of CAVB in preterm newborns managed using electro-stimulation with an external, followed by an internal pacemaker. Results and long-term follow-up were satisfactory in all three children.(More)
BACKGROUND Bronchiolitis is a potentially life-threatening respiratory illness commonly affecting children who are less than two years of age. Patients with viral lower respiratory tract infection are at risk for co-bacterial infection. AIM The aim of our study was to evaluate the use of C-reactive protein (CRP) in predicting bacterial co-infection in(More)
