- PURPOSE: To study pain perception in 10-15-year-olds, during and after uncomplicated extractions of bilateral maxillary premolars. The study investigated pain's natural course and made comparisons between the first and second extractions. METHODS: 31 Swedish children in need of orthodontic treatment were identified and consecutively enrolled. Tooth extractions followed a standardised protocol and the two teeth were extracted with at least 10 days between. The participants rated pain intensity using visual analogue scale (VAS) at 14 different time points from treatment and 7 days forward. RESULTS: The pain intensity profile followed the same pattern for all patients. Pain intensity peaked 2 h after extractions (mean VASPI 27.3, SD 20.8; median 23.0) when moderate pain intensity (VASPI >/= 40) was registered for 16 (28%) of 57 cases. After that, there was a rapid decrease in pain intensity notable already at 4 h after extractions. There were no statistically significant differences in any VASPI measurements between the first and second extractions, sexes, or different age groups. CONCLUSIONS: The majority of the participants who undergo uncomplicated bilateral extraction of maxillary premolars experience mild to moderate levels of postoperative pain during a short period of time, with no differences between the first and second extractions. Bilateral tooth extractions is a suitable model for further studies on pain management.

- Background: Data are conflicting regarding the role of endogenous sex hormones in colorectal carcinogenesis. In this large population-based study, we pooled data from birth and cancer registries in four Nordic countries, to evaluate the risk of colorectal adenocarcinoma in relation to women's reproductive history. Methods: We conducted a population-based case-control study among women registered in Nordic birth registries. The study included colorectal adenocarcinoma cases diagnosed in Denmark, Finland, Norway, and Sweden during 1967-2013 and up to 10 matched controls per case, in total 22 185 cases and 220 246 controls. Odds ratios (ORs) with 95% confidence intervals (95% CIs) were derived from conditional logistic regression models. We had limited information available on possible confounders. Results: We found no evidence for associations between colorectal adenocarcinoma and parity, age at first and last birth, and time since first and last birth. The risk estimates were also close to unity for specific cancer subsites (proximal and distal colon and rectum). As well, when the analyses were stratified on menopausal status, parity, and mother's year of birth, no indication of associations was found. Conclusions: In this large, Nordic population-based study, no evidence for associations was found between women's reproductive history and colorectal adenocarcinoma in parous women.

- Background: It remains unknown whether incident chronic diseases are more often fatal among breast cancer survivors than among women free of breast cancer. Methods: We conducted a nationwide matched cohort study of all Danish breast cancer patients diagnosed between 1994 and 2007, who survived for five years. We compared their long-term mortality with five times as many women from the general population without breast cancer, matched on age. We used time-varying methods to compute mortality rate ratios (MRRs) for incident diseases included in the Charlson Comorbidity Index (CCI). Results: One third of five-year breast cancer survivors developed incident diseases during 14 years of follow-up, with about the same incidence as women without breast cancer. Mortality associated with any incident disease was similar among breast cancer survivors (MRR = 7.1, 95% confidence interval (CI): 6.7, 7.4) and comparison women (MRR = 7.5, 95% CI: 7.3, 7.7). Among breast cancer patients, relative mortality associated with incident diseases was higher among patients treated with chemotherapy (MRR = 10, 95% CI: 8.7, 12) and radiotherapy (MRR = 9.8, 95% CI: 8.8, 11) than among patients who received surgery (MRR = 7.0, 95% CI: 6.7, 7.4) or hormonal therapy (MRR = 6.3, 95% CI: 5.8, 6.9). Conclusion: There were no marked differences in mortality of diseases among breast cancer survivors and women from the general population. Among breast cancer patients, new diseases were more often fatal in patients treated with chemotherapy and radiotherapy. Five-year breast cancer survivors have similar risk of dying from new chronic medical conditions as women from the general population without breast cancer.

- Epithelial ovarian cancer is a fatal disease of largely unknown etiology. Higher parity is associated with reduced risk of ovarian cancer. However, among parous women, the impact of pregnancy-related factors on risk is not well understood. This population-based case-control study included all parous women with epithelial ovarian cancer in Denmark, Finland, Norway and Sweden during 1967-2013 (n = 10,957) and up to 10 matched controls (n = 107,864). We used conditional logistic regression to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for pregnancy-related factors and ovarian cancer risk by histological subtype. Preterm delivery was associated with an increased risk [pregnancy length (last pregnancy) 30 vs. 39-41 weeks, OR 1.33 (95% CI 1.06-1.67), adjusted for number of births]; the OR increased as pregnancy length decreased (p for trend < 0.001). Older age at first and last birth was associated with a decreased risk [first birth: 30-39 vs. <25 years: adjusted OR 0.76 (95% CI 0.70-0.83); last birth 30-39 vs. <25 years: adjusted OR 0.76 (95% CI 0.71-0.82)]. Increasing number of births was protective [>= 4 births vs. 1; OR 0.63 (95% CI 0.59-0.68)] for all subtypes, most pronounced for clear-cell tumors [OR 0.30, (95% CI 0.21-0.44), p(heterogeneity)<0.001]. No associations were observed for multiple pregnancies, preeclampsia or offspring size. In conclusion, in addition to high parity, full-term pregnancies and pregnancies at older ages were associated with decreased risk of ovarian cancer. Our findings favor the cell clearance hypothesis, i.e. a recent pregnancy provides protection by clearing of precancerous cells from the epithelium of the ovary/fallopian tubes, mediated by placental or ovarian hormones.

- OBJECTIVES: Cure rates improve when adolescents and young adults with acute lymphoblastic leukemia (ALL) are treated according to pediatric protocols. Assumed risks of toxicities and associated delays in treatment have played a role in setting upper age limits. The aim of this study was to examine the toxicity profile and treatment delays in NOPHO ALL2008 comparing children and adults.METHODS: We collected information on 19 treatment-related toxicities, systematically captured at 3-month intervals throughout therapy, and time intervals between 12 consecutive treatment phases for 1076 patients aged 1-45 yrs treated according to the Nordic/Baltic ALL2008 protocol.RESULTS: No adults died during induction. The duration of induction therapy and postinduction treatment phases did not differ between children and adults, except for patients 18-45 yrs being significantly delayed during two of nine high-risk blocks (median number of days for patients 1-9, 10-17, and 18-45 yrs; the glucocorticosteroid/antimetabolite-based block B1: 24, 26, and 29 d, respectively, P = 0.001, and Block 5 (in most cases also a B block): 29, 29, and 37 d, respectively, P = 0.02). A higher incidence of thrombosis with increasing age was found; highest odds ratio 5.4 (95% CI: (2.6;11.0)) for patients 15-17 yrs compared with children 1-9 yrs (P < 0.0001). Risk of avascular osteonecrosis was related to age with the highest OR for patients 10-14 yrs (OR = 10.4 (95% CI: (4.4;24.9)), P < 0.0001).CONCLUSION: Adults followed and tolerated the NOPHO ALL2008 protocol virtually as well as children, although thrombosis and avascular osteonecrosis was most common among adolescents.

- Certain features of pregnancy are important risk factors for breast cancer, such as protection afforded by young age at first birth. Preeclampsia, a pregnancy complication, is associated with reduced maternal breast cancer risk. However, questions remain regarding causality, biological mechanisms and the relation of other hypertensive conditions to risk. We conducted a population-based case-control study of breast cancer cases (n = 116,196) in parous women identified through linkage of birth and cancer registries in Denmark, Finland, Norway and Sweden (1967-2013), including up to 10 matched controls per case (n = 1,147,192) sampled from the birth registries (complete data were not available on all variables). Odds ratios (ORs) with 95% confidence intervals (CIs) were derived from unconditional logistic regression models including matching factors (country, maternal birth year) and parity. Hypertension diagnosed before pregnancy (OR 0.87; 95% CI 0.78-0.97), gestational hypertension (OR 0.90; 95% CI 0.86-0.93) and preeclampsia (OR 0.91; 95% CI 0.88-0.95) were associated with reduced breast cancer risk. Results remained similar after adjustment for smoking and maternal body mass index before first pregnancy, and were generally similar stratified by parity, age at breast cancer diagnosis, time since first and last birth, sex of the offspring and calendar time. Except for retained placenta (OR 1.14; 95% CI 0.98-1.32), no other pregnancy complication appeared associated with breast cancer risk. The mechanisms mediating the modest risk reductions for history of preeclampsia or hypertension preceding or arising during pregnancy, and possible increased risk with history of retained placenta are unknown and warrant further laboratory, clinical and epidemiological investigation.
