  • Klinefelter's syndrome and taurodontism. [Journal Article]
  • AIArch Ital Urol Androl 2019 Jul 02; 91(2)
  • Giambersio E, Barile V, Giambersio AM
  • CONCLUSIONS: Our results confirm the higher prevalence of taurodontism in Klinefelter's patients compared to the normal population (12.5% vs. 2.0%). Due to the wide discrepancy of incidence of taurodontism reported in literature (0.04%-48.0% in normal population; 12.5%-88.0% in Klinefelter's patients), we conclude that it is not possible to state which is the prevalence of taurodontism in a normal population nor among Klinefelter's patients.
  • Why pediatricians need to know the disorders of sex development: experience of 709 cases in a specialized service. [Journal Article]
  • JPJ Pediatr (Rio J) 2019 Jun 27
  • Beck MSE, Germano CW, … Guerra-Júnior G
  • CONCLUSIONS: This study presents the largest series in the literature of patients with DSD treated in a single center. The time of referral of the majority of patients with ambiguous genitalia fell short of the ideal, and milder cases of ambiguous genitalia and many with pubertal manifestations were referred even later. The results reinforce the importance of continuing education for professionals who will have the first contact with these patients, mainly pediatricians and neonatologists.
  • Autism and social anxiety in children with sex chromosome trisomies: an observational study. [Journal Article]
  • WOWellcome Open Res 2019; 4:32
  • Wilson AC, King J, Bishop DVM
  • CONCLUSIONS: An increased risk of autism was found in girls with 47,XXX karyotype, as well as in boys with 47,XXY or 47,XYY. Symptoms of social anxiety were increased in all three karyotypes. There was wide variation in psychiatric status of children with the same karyotype, suggesting that an extra sex chromosome affects developmental stability in a non-specific way, with a diverse range of possible phenotypes.
  • Effects of the Timing of Sex-Steroid Exposure in Adolescence on Adult Health Outcomes. [Journal Article]
  • JCJ Clin Endocrinol Metab 2019 Jun 13
  • Chan YM, Feld A, Lewis EJ
  • CONCLUSIONS: Despite having some limitations, Mendelian randomization studies suggest that pubertal timing causally influences many adult conditions and disease risks. Studies in Turner syndrome and Klinefelter syndrome suggest that earlier sex-steroid exposure may have short- and long-term benefits. The mechanisms underlying these findings and the effects of trends and treatments affecting pubertal timing remain to be determined.
