The trimester-specific effects of bisphenols on repeated measures of fetal growth remain unknown. Our objective was to assess the associations of maternal bisphenol urine concentrations with fetal growth measures and birth outcomes and identify potential critical exposure periods. In a population-based prospective cohort study among 1379 pregnant women, we measured maternal bisphenol A, S and F urine concentrations in the first, second and third trimester. Fetal head circumference, length and weight were measured in the second and third trimester by ultrasound and at birth. An interquartile range increase in maternal pregnancy-averaged bisphenol S concentrations was associated with larger fetal head circumference (difference 0.18 (95% confidence interval (CI) 0.01 to 0.34) standard deviation scores (SDS), p-value< 0.05) across pregnancy. When focusing on specific critical exposure periods, any detection of first trimester bisphenol S washt and a lower risk of being small size for gestational age at birth. Turner's syndrome, discoid meniscus, and Blount's disease have all been studied in isolation, but, to the best of our knowledge, there have been no studies reporting a patient with all three. Thus, the first case of Turner's syndrome with discoid meniscus and Blount's disease is presented. A 5-year-old Japanese girl with a history of Turner's syndrome and Blount's disease complained of pain in her left knee. Magnetic resonance imaging showed a discoid lateral meniscus tear, and arthroscopic partial meniscectomy was performed, providing a good outcome. In this report, some possible explanations regarding the concomitant presence of these three diseases are discussed. A possible explanation in this case is that the patient with Turner's syndrome had a discoid lateral meniscus that might have been induced by some genetic factors a
