Characteristics and prognosis of primary treatment-naïve oral cavity squamous cell carcinoma in Norway, a descriptive retrospective study.

Objectives: Incidence of oral cavity squamous cell carcinomas is rising worldwide, and population characterization is important to follow for future trends. The aim of this retrospective study was to present a large cohort of primary oral cavity squamous cell carcinoma from all four health regions of Norway, with descriptive clinicopathological characteristics and five-year survival outcomes.

Materials And Methods: Patients diagnosed with primary treatment-naïve oral cavity squamous cell carcinomas at all four university hospitals in Norway between 2005-2009 were retrospectively included in this study.

Birth characteristics and acute otitis media in early life.

Objective: To assess whether preterm birth and low birth weight were associated with single and recurrent episodes of acute otitis media (AOM) the first 18 months of life.

Methods: The study population consisted of 33,192 children in the Norwegian Mother and Child Cohort, conducted at the Norwegian Institute of Public Health. The majority of all pregnant women in Norway were invited to participate and the response rate was 44%.

Surgery for otitis media and infectious susceptibility in 10-year old school children.

Objectives: Assess infectious susceptibility in children previously operated for otitis media and evaluate reliability of parental reported otitis media surgery in the same group of children.

Methods: Population based, cross-sectional survey of 10-year olds in the city of Oslo, Norway studying otitis media and surgical intervention in n=3406 with reliability assessments in a subset of n=2027.

Results: Ten percent of children had otitis media surgery.

Trends in otitis media surgery: a decrease in adenoidectomy.

Objective: Large variability in adenoidectomies and tympanostomy tube insertions between Norway and Finland has been suggested, but not yet confirmed. Objective is to compare trends in paediatric adenoidectomies and tympanostomy tube insertions for Norway and Finland from 1999 to 2005.

Methods: National Finnish and Norwegian databases (STAKES and NPR) provided information on children between 0 and 7 years operated in the years 1999-2005.

Acute mastoiditis in Norway: no evidence for an increase.

Objective: In a large Norwegian newspaper in November 2005, an otolaryngologist at Rikshospitalet claimed that the increasing number of children hospitalized for acute mastoiditis was worrying and questioned the restrictive use of antibiotics in Norway. Based on latter he recommended that all children below age 2 with symptoms of uncomplicated acute otitis media should receive antibiotics. Our purpose was to incidence variation and characteristics of acute mastoiditis in children.

Early acute otitis media: predictor for AOM and respiratory infections in schoolchildren?

Objective: It has been reported that acute otitis media (AOM) and respiratory infectious morbidity still are common in schoolchildren. However, the significance of early initiation of AOM on later respiratory infections is not known. The aim of the study was to assess whether early initiation of AOM is a predictor for AOM and other respiratory infections in schoolchildren, and if environmental exposures and host factors in early life predict later AOM.

Otitis media surgery: large variability between Finland and Norway.

Objective: Bi-national comparison of surgical treatment for paediatric otitis media.

Methods: Registry based cross-sectional study with complete data on surgery for otitis media in 2002; 21,811 Finnish and Norwegian children aged 0-16 years.

Results: Total rates for otitis media surgery were 82.

Acute otitis media in schoolchildren: allergic diseases and skin prick test positivity.

Conclusions: Single and repeated episodes of acute otitis media (AOM) in 10-year-old children were associated with reported allergic disease. Further, skin prick test (SPT)-negative children with reported asthma and allergic rhinoconjunctivitis had increased risk of AOM. We suggest that optimal treatment of allergic symptoms may have an effect on AOM in school children.

Paediatric otitis media surgery in Norway.

Conclusions: In Norway there are large, regional differences in the incidence of surgery and combinations of surgery for otitis media.

Objectives: A descriptive study of complete national administrative data on frequency of surgery for otitis media in 2002.

Materials And Methods: This study analysed anonymous patient data from the Norwegian patient registry for 2002 and measured rates of tympanostomy tube insertions, myringotomy and the combinations of adenoidectomies and tympanostomy tubes and myringotomy, respectively.

Finnish adenoidectomy and tympanostomy rates in children; national variation.

Objectives: To assess upper respiratory surgery rates in Finnish children and compare the rates of adenoidectomy and tympanostomy tubes in 2002 with the 1987 cohort.

Methods: Descriptive study of national upper respiratory surgery in Finland in 1987 and 2002; adenoidectomies, tympanostomy tubes and combination of these two. Surgical rates were viewed in the light of child density and number of primary care physicians and otorhinolaryngologists.
