These findings suggest that the transmission of some periodontal pathogens from the oral cavity of the mother may cause adverse pregnancy outcomes. The results contribute to an understanding of the association between periodontal disease and PTLBW, but further studies are required to better clarify the possible relationship.

Background Food allergy is associated with stress, anxiety, and impairment in quality of life in both children and families. This study aimed to assess the anxiety of mothers in the case of suspected food allergy in their children and the influence of Internet usage on their levels of anxiety and food elimination. Methods Ninety‐two patients aged 0‐2 years presented at a pediatric allergy department following either a physicians' presumptive diagnosis or family's suspicion of food allergy (Group 1) and 99 healthy controls (Group 2) were evaluated. The clinical diagnosis of food allergy was confirmed or excluded by oral food challenge (OFC). The validated Turkish version of Spielberger State‐Trait Anxiety Inventory (STAI) was applied to the mothers of both groups on admission and to Group 1 3 months after OFC. Results The state and trait anxiety (STAI‐S and STAI‐T) scores were significantly higher in Group 1 than Group 2 (P < 0.001, z = 5.410, and P = 0.021, z = 2.304, respectively). Seventy‐nine mothers (85.9%) had been eliminating foods on admission. Thirty‐seven (40.2%) mothers had eliminated foods on their own. The performance of food allergy–related Web searches was significantly higher among mothers who eliminated foods by themselves than those who did not (P = 0.004, χ2 = 8.391, df = 1). The second STAI‐S score was significantly lower among mothers whose children's food allergy diagnosis was excluded than confirmed (effect size = 1.06 (95% CI: 0.56‐1.57), P = 0.001, z = 3.442). Conclusion It is important to make a correct food allergy diagnosis with a detailed allergy work‐up, including OFC, to avoid anxiety and not cause unnecessary food elimination.

Background: Environmental and dietary factors during pregnancy may affect development of infantile atopic dermatitis (AD). This study analyzed whether maternal consumption of selected Turkish fermented foods (FF) and other factors during pregnancy affect the development of AD during the first 2 years of life.Methods: Eighty-four children with physician-diagnosed AD (aged between 2 and 24 months) and mothers, and 56 similarly aged, healthy children and mothers were studied. Physician-administered questionnaires retrospectively surveyed maternal consumption of FF during pregnancy. The intake frequency of 8 selected Turkish FF was classified as either (1) daily or (2) less than daily. Other possible demographic and environmental risk factors were also analyzed.Results: Daily maternal consumption of yogurt, fermented olive, and cheese in the control group was significantly higher than the AD group (P < 0.001, P = 0.017, and P = 0.011, respectively). Exposure to environmental tobacco smoking (ETS) was more common in the AD group than the control group (P = 0.025). In multivariate logistic regression analysis, maternal ETS exposure during pregnancy was associated with increased risk of infantile AD, and daily consumption of yogurt was associated with a reduced risk (odds ratio [OR]: 2.60, 95% confidence interval [CI]: 1.11-6.

A hospital-based case-control study was carried out among 504 women with breast cancer and 610 controls to analyse the risk factors for breast cancer in Turkey. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for each risk factor were obtained from logistic regression analysis. Risk factors for breast cancer were found to be long-term lactation (> or = 5 years versus never OR 0.31, 95% CI 0.12-0.79), young age at menarche (< 15 years versus > or = 15 OR 1.72, 95% CI 1.30-2.28), late age at first full-term pregnancy (> or = 30 versus < 20 OR 2.86, 95% CI 1.32-6.21), oral contraceptive use (ever versus never OR 1.51, 95% CI 1.10-2.08), positive family history (positive versus negative OR 2.81, 95% CI 1.35-5.82), and menstrual irregularity (yes versus no OR 1.61, 95% CI 1.05-2.49). The results of the present study will lead to a better understanding of the risk factors for breast cancer in a developing country.
