Affirming Pediatric Care for Transgender and Gender Expansive Youth.

Transgender and gender diverse children and youth experience significant health disparities and adverse health outcomes. Pediatricians have an opportunity to improve those outcomes by practicing gender-affirming care. This includes creating a welcoming environment through changes in office settings, intake forms, communication skills, language used, and support for families. Clinicians should be comfortable discussing social transition, puberty blockers, and gender-affirming hormone therapy with patients as needed. For clinicians caring for teenagers, adaptations in sexual health counseling and fertility counseling are necessary. Clinicians should also be aware of the trauma that has been historically inflicted by the medical and mental health system against people who identify as transgender/nonbinary, and that significant disparities exist even within this group along racial and gender lines. These aspects of caring for gender diverse youth are part of primary care pediatrics, and further education in these areas will improve access to care and health outcomes for these youth.

Identification of a prenatal profile of Cornelia de Lange syndrome (CdLS): a review of 53 CdLS pregnancies.

Cornelia de Lange Syndrome (CdLS) is a multisystem developmental disorder characterized by growth retardation, cognitive impairment, external and internal structural malformations, and characteristic facial features. Currently, there are no definitive prenatal screening measures that lead to the diagnosis of CdLS. In this study, documented prenatal findings in CdLS syndrome were analyzed towards the development of a prenatal profile predictive of CdLS. We reviewed 53 cases of CdLS (29 previously reported and 24 unreported) in which prenatal observations/findings were available. The review of these cases revealed a pattern of sonographic findings, including obvious associated structural defects, growth restriction, as well as a more subtle, but strikingly characteristic, facial profile, and suggestive of a recognizable prenatal ultrasonographic profile for CdLS. In addition, the maternal serum marker, PAPP-A, may be reduced and fetal nuchal translucency (NT) may be increased in some pregnancies when measured at an appropriate gestational age. In conclusion, CdLS can be prenatally diagnosed or readily ruled out in a family with a known mutation in a CdLS gene. The characteristic ultrasonographic profile may allow for prenatal diagnosis of CdLS in (1) subsequent pregnancies to a couple with a prior child with CdLS in whom a mutation has not been identified or (2) when there are unexplained pregnancy signs of fetal abnormality, such as oligo- or polyhydramnios, a low maternal serum PAPP-A level and/or increased NT, fetal growth retardation, or structural anomalies consistent with CdLS.

Causes of death and autopsy findings in a large study cohort of individuals with Cornelia de Lange syndrome and review of the literature.

To identify causes of death (COD) in propositi with Cornelia de Lange syndrome (CdLS) at various ages, and to develop guidelines to improve management and avoid morbidity and mortality, we retrospectively reviewed a total of 426 propositi with confirmed clinical diagnoses of CdLS in our database who died in a 41-year period between 1966 and 2007. Of these, 295 had an identifiable COD reported to us. Clinical, laboratory, and complete autopsy data were completed on 41, of which 38 were obtainable, an additional 19 had autopsies that only documented the COD, and 45 propositi had surgical, imaging, or terminal event clinical documentation of their COD. Proband ages ranged from fetuses (21-40 weeks gestation) to 61 years. A literature review was undertaken to identify all reported causes of death in CdLS individuals. In our cohort of 295 propositi with a known COD, respiratory causes including aspiration/reflux and pneumonias were the most common primary causes (31%), followed by gastrointestinal disease, including obstruction/volvulus (19%). Congenital anomalies accounted for 15% of deaths and included congenital diaphragmatic hernia and congenital heart defects. Acquired cardiac disease accounted for 3% of deaths. Neurological causes and accidents each accounted for 8%, sepsis for 4%, cancer for 2%, renal disease for 1.7%, and other causes, 9% of deaths. We also present 21 representative clinical cases for illustration. This comprehensive review has identified important etiologies contributing to the morbidity and mortality in this population that will provide for an improved understanding of clinical complications, and management for children and adults with CdLS.
