Patients with recurrent respiratory papillomatosis (RRP) in Norway treated between 1987 and 2009 were recruited to this cohort study. They were followed from disease onset and data recorded until January 2012. Here, we describe the distribution of human papillomavirus (HPV) genotypes, the prevalence of multiple HPV infections, and the risk of high-grade(More)
In this cohort study we examined whether gender, age at onset, observation time or human papillomavirus (HPV) genotype are risk factors for an aggressive clinical course in Recurrent Respiratory Papillomatosis (RRP). Clinical data from patient records comprised gender, age at onset, date of first endolaryngeal procedure with biopsy, date of last follow-up,(More)
The aim of the present study was to evaluate the effect of laser-assisted uvulopalatoplasty (LUPP) performed under local anesthesia in an outpatient setting. No procedure included tonsillectomy. Obstruction related mainly to the velopharyngeal segment of the airway was defined in 16 consecutive patients by clinical examination, nocturnal polysomnography and(More)
OBJECTIVES To assess the clinical value of pulseoximetry in the diagnosis of sleep apnea when satisfactory agreement with polysomnography is obtained. METHODS This was a prospective clinical study, set in the Department of Otorhinolaryngology, Ullevaal University Hospital, Oslo, Norway. One hundred consecutive patients were investigated for sleep related(More)
Mouth breathing may contribute to increased collapsibility of the upper airways because of decreased contractile efficiency of the upper airway muscles as a result of mouth opening. Nasal airflow is also hypothesized to have a stimulating effect on the respiratory drive via receptors in the nose. Accordingly, patients with sleep-related breathing disorders(More)
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)
Objective is to investigate the relationship between migraine and obstructive sleep apnea in the general population. 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 by the National Population Register. A postal(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)
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)
The aim of the present study was to investigate the prevalence of obstructive sleep apnea syndrome (OSAS) among the Norwegian population with Treacher Collins syndrome (TCS). A secondary aim was to establish whether TCS phenotype severity is associated with OSAS severity. A prospective case study design was used. Individuals who were 5 years old and above(More)
