BACKGROUND Heart rate variability (HRV) is an accepted and reliable means for assessing autonomic nervous system dysfunction. A 5-minute measurement of HRV is considered methodologically adequate. Several studies have attempted to use shorter recordings of 1-2 minutes or 10 seconds. The aim of this study was to determine the reliability of HRV parameters(More)
We compared the effect of haematopoietic growth factors granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin (IL)-1, IL-3, and IL-5 on the functional activation of human eosinophils and neutrophils from the same donor. All four colony-stimulating factors (CSF) enhanced the phagocytosis of Candida albicans by eosinophils and increased(More)
One hundred and seven chronically wheezing infants, aged 6 months to 3 years, completed a double-blind placebo controlled multicenter study. After a two-week baseline period the patients were randomized into two groups receiving twice daily either ketotifen or placebo for a period of 12 weeks. The ketotifen dosage was 0.5 mg for children younger than one(More)
OBJECTIVE Otitis externa (OE), also known as "swimmer's ear", is an inflammation or infection of the external auditory canal. Many risk factors have been identified, mainly excessive moisture in the canal from swimming. STUDY DESIGN/METHODS To study the leading risk factors of otitis externa. Eighty-seven children aged 3.5-12 years (mean 68+/-6.5 months)(More)
During the years 1987-1988, an outbreak of mumps was reported among the paediatric population in Israel. Mumps immunization in Israel was not universal at that time and most of the population had not been immunized. During that period, 66 children with evidence of recent mumps parotitis with several complications, i.e. meningo-encephalitis, cerebellar(More)
Inhaled budesonide has been demonstrated to be effective and safe when it is used in the prophylaxis of severe asthma in adults and school-age children but has not been studied in younger patients with asthma. Sixteen children, aged 3 1/2 to 7 years, with severe asthma, were treated with budesonide aerosol, 200 micrograms daily, via a spacer for 1 year in(More)
Our objective was to investigate the impact of increased asthma awareness among primary care physicians on the asthma control and satisfaction of their patients. Physicians attended an asthma education session with emphasis on patient-physician partnership followed by 4 month monitored follow-up of patients aged 5-44 years with mild to moderate asthma.(More)
This 6-month, open-label extension study of a previously described base study compared oral montelukast with inhaled beclomethasone in terms of safety, forced expiratory volume in one second (FEV1) measurements, parent and patient satisfaction with treatment, asthma-related medical resource utilization, school absenteeism, and parental work loss in children(More)
Two hundred and fifteen children aged 4 months–6 years with acute otitis media (AOM) were randomized to be treated either by a single i.m. injection of ceftriaxone, 50 mg/kg, with a second dose in the event of unsatisfactory response after 48 h or a history of recurrent AOM (109 patients) or amoxicillin clavulanate 12.5 mg tid (106 patients). The failure(More)
