The main objective of this study is to investigate the relationship between tension-type headache and obstructive sleep apnea in the general population. The method involves a cross-sectional population-based study. A random age and gender stratified sample of 40,000 persons aged 20-80 years residing in Akershus, Hedmark or Oppland County, Norway were drawn(More)

A random age and gender stratified sample of 40,000 persons aged 20-80 years residing in Akershus, Hedmark or Oppland County, Norway, were drawn by the National Population Register. A postal(More)
PURPOSE To explore the associations between sleep hypoventilation (SH) and daytime arterial pressures of carbon dioxide (PaCO2), sleep stages, and sleep apneas/hypopneas (AHI) in subjects with chronic obstructive pulmonary disease (COPD). SH has previously been found in COPD-subjects with chronic hypercapnic respiratory failure (CHRF) using supplementary(More)
This study examines the prevalence of hearing loss in children with Down syndrome at the age of 8. All children were examined in the ENT-departments of public hospitals in Norway and the study population consisted of children born in Norway in 2002 with Down syndrome. Hearing loss was defined as pure-tone air-conduction reduction by on average more than 25(More)
Studies of the Treacher-Collins syndrome have emphasized hearing and surgical considerations. Although craniofacial anomalies have been associated with respiratory disorders in infancy, the presence of such problems in older children has not been emphasized. An eight-year-old with Treacher-Collins syndrome presented a history of recent behavioral problems(More)
Although the relationship between Quality of Life (QoL) and obstructive sleep apnea (OSA) has been reported in several studies, little is known about this relationship among individuals affected with Treacher Collins syndrome (TCS). The aim of this study was to examine the associations between obstructive sleep and QoL in TCS patients. Thirty-six(More)
The aim of this study was to explore and compare the effect of noise from railway and road traffic on sleep in subjects habitually exposed to nocturnal noise. Forty young and middle aged healthy subjects were studied with polysomnography (PSG) during two consecutive nights in their own bedroom. Noise measurements and recordings were conducted concurrently(More)
BACKGROUND The objective was to investigate the prevalence and clinical characteristics of sleep apnoea headache. METHODS A postal questionnaire was received by 40,000 Norwegians from the general population. A total of 376 and 157 persons with high and low risk of sleep apnoea according to the Berlin Questionnaire had a polysomnography, and a clinical(More)
BACKGROUND Sleep-disordered breathing (SDB) is common in patients with reduced ejection fraction (EF). However, little is known about the prevalence of SDB in a general heart failure population including patients with preserved EF (HFPEF). METHODS We prospectively enrolled stable heart failure outpatients from our heart failure clinic to assess the(More)
BACKGROUND In individuals with simple hypodontia, congenital absence of teeth commonly affects just one tooth of a pair, not both. However, patterns of hypodontia have not been fully explored in children with Down syndrome (DS). OBJECTIVE We describe the frequency and left-right symmetry of hypodontia in the permanent dentition of 8- to 9-year-old(More)
