Abstract
The indications for operative treatment of lateral tibial plateau fractures are still controversial. The objective of this study was to determine whether residual articular surface depression and valgus malalignment of plated lateral tibial plateau fractures at medium-term follow-up affect the clinical and radiographic outcomes.
A chart review of patients with operatively treated (AO type B3.1) tibial plateau fractures that were admitted to our level I trauma center between 2002 and 2008 was performed. Out of 123 patients, 73 were available to participate in a clinical and radiographic follow-up examination. The mean follow-up time was 54 months. Patients were clinically assessed and completed the Lysholm knee score and Western Ontario and McMaster Universities Osteoarthritis Index. Maximal articular surface depression, radiological mechanical axis, and degree of posttraumatic osteoarthritis were evaluated from standing radiographs.
Patients with valgus malalignment of 5° or greater at follow-up developed more advanced osteoarthritis (Kellgren-Lawrence grade 3-4) than patients with a normal mechanical axis (p = 0.006). Similarly, patients with articular depression greater than 2 mm at follow-up also developed more advanced osteoarthritis compared to patients with a depression of 2 mm or less (p = 0.001). The degree of valgus malalignment or articular depression had no effect on the Western Ontario and McMaster Universities Osteoarthritis Index or Lysholm scores.
The postoperative articular congruity and normal mechanical axis of the lower leg after plate fixation in lateral tibial plateau fractures seem to have a role in prevention of posttraumatic osteoarthritis but does not appear to predict clinical outcome at medium-term follow-up. The role of initial dislocation and associated cartilage damage in the development of osteoarthritis following these fractures is still unknown.

Abstract
This study evaluated the long-term effects of a school- and community-based smoking prevention program in Finland.
Four intervention schools from North Karelia and two control schools from another province were chosen for the evaluation. Students who received the intervention were taught to resist social pressures to smoke. The program began in 1978 with seventh-grade students and ran through 1980, with a 15-year follow-up. In North Karelia, a community-based smoking cessation program for adults was also carried out.
Mean lifetime cigarette consumption was 22% lower among program subjects than among control subjects. Smoking and prevalence were lower up to the age of 21.
Long-term smoking prevention effects can be achieved if a school-based program using a social influence model is combined with community and mass media interventions.

Abstract
Retinal detachments have a tendency to occur more commonly in spring and summer than in winter. Two new series are presented here, the first collected in Northern Finland at latitudes 64 degrees-70 degrees and the second from Novosibirsk, at a much lower latitude, 55 degrees N, but with an equally long winter. A statistically significant seasonal variation is found in both. The highest incidence peak is seen in June in Oulu and in July in Novosibirsk, the difference between the prevalence curves was, however, not statistically significant. The Oulu series shows a statistically highly significant seasonal variation in low refractive errors but no seasonal difference in high myopia and aphakia.

Abstract
Shoulder capsular surgery is nowadays usually performed arthroscopically, and the proportion of arthroscopic method has rapidly increased during the last two decades. We assessed the incidence of shoulder capsular surgery procedures in Finland between 1999 and 2008.
We gathered the shoulder capsular surgery procedures for all kinds of shoulder instability in Finland between 1999 and 2008 from National Hospital Discharge Register and limited the patient material to include only certain diagnosis (International Classification of Diseases, 10th Edition) and Nordic Medico-Statistical Committee procedure code combinations. We analyzed the data in the whole country, between different age groups, and in university hospital districts.
The total incidence of shoulder capsular surgery procedures in Finland increased from 17 to 33 per 100,000 person-years. The incidence of arthroscopic procedures increased from 11 to 30 per 100,000 person-years and the proportion of arthroscopic procedures increased from 63% to 92% between years 1999 and 2007. The incidence of shoulder capsular surgery procedures increased on average around 90% in almost all age groups and particularly in the older age groups. We observed no significant geographical variation between university hospital districts.
The incidence of shoulder capsular surgery procedures increased on average round 90% in almost all age groups. It seems to be difficult to support the rapidly increased rates of shoulder capsular surgery procedures or the arthroscopic method based on scientific evidence. While also older patients are treated with shoulder capsular surgery, well-defined indications for surgical intervention are needed so that the operations are conducted for the symptomatic patients benefitting most regardless of patients' age.

Abstract
Most smokers begin smoking in adolescence. It is less well known how young people quit smoking and the factors that are associated with this process. A 15-year follow-up study on the North Karelia Youth Project has made it possible to assess these factors using a longitudinal study design. The project began in 1978 with students in Grade 7 of junior high school (age 13 years) and concluded in 1980 when the students reached Grade 9 (age 15 years). The follow-up study included four additional surveys. The present analyses are based on the data collected at ages 15, 21 and 28. The original sample comprised 903 students and the response rate of the last survey was 71%. A quarter (26%) of daily smokers and about half (46%) of occasional smokers at age of 15 had quit by the age of 28. The cessation rate was higher among females than males (P = 0.006). The cessation rate was higher among married (P = 0.015), employed (P = 0.01) and white-collar workers (P = 0.006). Cessation was less prevalent among those who had friends (P

Abstract
The main purpose of this study was to explore how the number of home, sports, and other leisure time injuries among young people aged 15 - 25 years has developed in Finland in 1988 - 2003. In 1988, 2559 people aged 15 - 25 years were interviewed by Statistics Finland. In 1993, 1997 and 2003 those amounts were 751, 1638 and 1382. The subjects were asked in a telephone interview to report the injuries in which they had been involved during the previous 12 months. The crude injury incidence in 2003 was 364 per 1000 person years in men and 246 in women. The total number of injuries increased 49 % between the years 1988 and 2003. The number of sports injuries increased the most. The increase was greater among men than women, and the injury rate was higher among both men and women aged 15 - 19 years than those aged 20 - 25 years. More research is needed on whether and how exercise and time at home have changed and become riskier among young people. It is also essential to find out which prevention methods are the most effective among young people and implement these measures in a well-planned and targeted manner.
