Influence of Maternal Diabetes on the Risk of Neurodevelopmental Disorders in Offspring in the Prenatal and Postnatal Periods.

BACKGROUND: This study aimed to evaluate the influence of maternal diabetes in the risk of neurodevelopmental disorders in offspring in the prenatal and postnatal periods. METHODS: This cohort study included singleton gestational diabetes mellitus (GDM) pregnancies >22 weeks' gestation with live newborns between 1991 and 2008. The control group was randomly selected and matched (1:2) for maternal age, weeks of gestation and birth year. Cox regression models estimated the effect of GDM on the risk of attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and maternal type 2 diabetes mellitus (T2DM). Moreover, interaction between maternal T2DM and GDM-ADHD relationship was evaluated. RESULTS: Children (n=3,123) were included (1,073 GDM; 2,050 control group). The median follow-up was 18.2 years (interquartile range, 14.2 to 22.3) (n=323 with ADHD, n=36 with ASD, and n=275 from women who developed T2DM). GDM exposure was associated with ADHD (hazard ratio [HR]crude, 1.67; 95% confidence interval [CI], 1.33 to 2.07) (HRadjusted, 1.64; 95% CI, 1.31 to 2.05). This association remained significant regardless of the treatment (diet or insulin) and diagnosis after 26 weeks of gestation. Children of mothers who developed T2DM presented higher rates of ADHD (14.2 vs. 10%, P=0.029). However, no interaction was found when T2DM was included in the GDM and ADHD models (P>0.05). GDM was not associated with an increased risk of ASD (HRadjusted, 1.46; 95% CI, 0.74 to 2.84). CONCLUSION: Prenatal exposure to GDM increases the risk of ADHD in offspring, regardless of GDM treatment complexity. However, postnatal exposure to maternal T2DM was not related to the development of ADHD.

Adenoma de células de Sertoli bilateral en paciente con síndrome de insensibilidad a los andrógenos / Bilateral Sertoli cell adenoma in a patient with androgen insensitivity syndrome

El síndrome de insensibilidad a los andrógenos se caracteriza por la presencia de fenotipo femenino, gónadas masculinas y cariotipo 46,XY. Es la causa más común de seudohermafroditismo masculino y la tercera causa más frecuente de amenorrea primaria, después de la disgenesia gonadal y la ausencia congénita de vagina. Es una entidad cuya importancia radica en su diagnóstico precoz en la pubertad por el riesgo de desarrollo de tumoraciones testiculares. En este artículo se presenta un caso de diagnóstico tardío de síndrome de insensibilidad a los andrógenos asociado a adenoma de células de Sertoli (AU)

Androgen insensitivity syndrome is characterized by the presence of a female phenotype, masculine gonads, and 46,XY karyotype. This syndrome is the most common cause of masculine pseudohermaphroditism and is the third most frequent cause of primary amenorrhea after gonadal dysgenesis and congenital absence of the vagina. The importance of this entity lies in its early diagnosis in puberty because of the risk of testicular tumors. In this article, we present a case of late diagnosis of androgen insensitivity syndrome related to Sertoli cell adenoma (AU)
