Abstract
BACKGROUND Centrally collected Finnish national health register data on adverse pregnancy outcomes are available for research, but the validity of the data is largely unknown. Our aim was to compare the diagnoses of preeclampsia (PE), gestational diabetes (GDM), and preterm delivery from hospital records with the registry based diagnoses from the Finnish Care Register for Health Care (FCR). Data on gestational age at delivery from the Medical Birth Registry (MBR) was also studied. METHODS The Finnish Genetics of Pre-eclampsia Consortium (FINNPEC) Study cohort was used as a data source. Each diagnosis was ascertained from electronic hospital records. The validity of diagnoses obtained by record linkage of FCR and MBR was assessed against the classification previously confirmed independently by a research nurse and a study physician. RESULTS Sensitivity of PE diagnoses in FCR was 80.3 % (95 % CI 78.3 % to 82.2 %) andspecificity 95.3 % (95 % CI 93.9 % to 96.4 %). Sensitivity for GDM was 64.1 % (95 % CI: 58.7 % - 69.3 %) and specificity 98.5 % (95 % CI: 97.9 % - 98.9 %), whereas sensitivity and specificity for preterm delivery were 32.4 % (95 % CI: 29.0 % - 36.0 %) and 99.7 % (95 % CI: 99.3 % - 99.9 %). Sensitivity of preterm delivery in the MBR was 99.1 % and specificity 99.9 %. CONCLUSIONS FCR registry diagnoses for PE have satisfactory sensitivity and high specificity. Diagnoses for GDM and preterm delivery have lower sensitivity limiting their use in studies, and data from MBR should be preferred when studying preterm deliveries.

Abstract
BACKGROUND Many surgical procedures have been described for hallux valgus. Evidence provided by the current literature on the different procedures is, however, poor. The purpose of this study was to assess the incidence of HV surgery in Finland between 1997 and 2014 and to find out whether changes in operation techniques of HV have occurred during the study period. METHODS The study included all adult patients (≥18 years) who underwent primary HV operation. Patients were included into study if they had been operated with a diagnosis of HV (ICD-10 code M20.1). The data were collected by the Finnish National Hospital Discharge Register (NHDR). RESULTS The total incidence of primary HV operations was 66.7 per 100,000 person-years in 1997 and 41.4 per 100,000 person-years in 2014. The incidence of arthroplasty operations of the MTP-1 joint decreased while at the same time the incidence of the MTP-1 joint arthrodesis and TMT-1 arthrodesis increased. The gender difference (13% men, 87% women) is consistent with previous studies. CONCLUSION This study shows a significant decreasing trend of HV operations in Finland between 1997 and 2014. During the study period, the incidence of MTP I joint arthroplasty decreased, and since 2005 the incidence of MT-1-osteotomies has almost halved. At the same time, the incidence of MTP-1 joint arthrodesis increased by over 1000% and TMT-1 joint arthrodesis by nearly 2000%.

Abstract
OBJECTIVE Varicella vaccine was recommended in the Community of Madrid (CM) at 15months of age between November 2006 and December 2013. The objective was to describe the impact of vaccination on the incidence of varicella in the CM during the period 2001-2015. DESIGN A descriptive study of cases of varicella reported to the Sentinel Physician Network of the CM and the cases recorded in the Minimum Basic Data Set at hospital discharge was carried out. Total incidence of cases and of hospital admissions were calculated, as well as specific incidence by age and sex. RESULTS The incidence was 94.0% lower between 2012 and 2013 than between 2001 and 2003. Between 2014 and 2015 the incidence was 61.8% higher than between 2012 and 2013. The highest incidence was observed in children aged 0 to 4years except for 2010-2014, which was exceeded by the incidence in children aged 5 to 9. The trend in hospital admissions was also decreasing, with the highest incidence in children aged 0 to 1year, followed by 1-4years. CONCLUSIONS There has been a significant decrease in the incidence of cases and of hospital admissions by varicella in all age groups after the recommendation to vaccinate at 15months of age, which is compatible with the effectiveness of a dose and its ability to produce immunity group. The withdrawal of this recommendation between 2014 and 2015 has led to an increase in the incidence.

Abstract
BACKGROUND Clavicle fractures are among the most common upper extremity injuries. Traditionally most clavicle fractures have been treated non-surgically, but during recent decades the surgical treatment of clavicle fractures has increased. The purpose of this study was to assess the numbers and trends of surgically treated clavicle fractures in Finland between 1987 and 2010. METHODS The study covered the entire adult (>18 years) population of Finland over the study period. Data on surgically treated clavicle fractures was collected from the Finnish National Hospital Discharge Register. We assessed the number and incidence of surgically treated clavicle fractures annually. RESULTS A total of 7073 surgically treated clavicle fractures were identified in the register over the study period. Three-fourths of the surgically treated patients were men and one-fourth was women. The incidence of surgical treatment increased nearly ninefold from 1.3 per 100,000 person years in 1987 to 10.8 per 100,000 person years in 2010. The increase in the rate of surgical treatment was especially notable in men. CONCLUSIONS A striking increase in incidence of surgically treated clavicle fractures was seen from 1987 to 2010. Although the actual incidence of clavicle fractures is not known, we assume that the proportion of patients receiving surgical treatment has increased markedly without high-quality evidence. Since recent reports have suggested similar functional results between operative and conservative treatment critical evaluation of the treatment policy of clavicle fractures is warranted.
