Introduction: Turner syndrome (TS) is a genetic condition with different phenotypic expressions depending on karyotype. Due to genetic prenatal testing, its prevalence is getting lower. The objective was to analyze the presence of different comorbidities associated with TS according to the karyotype and evaluate if there is follow-up in adulthood.Methods: Descriptive retrospective study including all the patients genetic...

Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. T2D is associated with metabolic-associated fatty liver disease (MAFLD). High-density lipoproteins (HDLs) are lipoproteins that are believed to have atheroprotective properties that reduce the risk of cardiovascular disease (CVD). Current evidence suggests that the physicochemical and functional features of HDLs may play a key role in the pathogenesis of atherosclerosis.<...

Background: The bone age (BA) assess the skeletal maturity and determine the children linear growth. Mexican children have a slightly delay in skeletal maturity before 10 years, but they reach in mean a BA 1 year in advance at the end of the puberty. On the other hand, Mexico has a high prevalence of childhood obesity and the adiposity has been associated with the BA advance in other populations. For the above, the overweight and obesity could be impact in the...

Introduction: Studies about pubertal onset and the menarcheal age in girls with the antecedent of idiopathic premature adrenarche (IPA) are limited and with discordant results. For these reasons, we created a cohort of girls with the diagnosis of IPA. The objectives of our study were: a) to know the age of pubertal onset; b) to evaluate menarcheal age; c) to determine the growth rate in the first two years after the IPA diagnosis; d) to collect adult height da...

Background: Emerging data suggest that ambulatory blood pressure (BP) monitoring for 24 h may be efficient in the diagnosis of hypertension in adults, children and adolescents. Additionally, in adults, it may predict the existence of some early BP abnormalities related to cardiovascular risk: (a) elevated BP load (>25%) and (b) non-dipping (BP decrease in night-time <10%).Objective and hypotheses: To evaluate the presence of early BP abnormalitie...

Introduction: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. Moreover it was demonstrated that the ZnT family plays an important role in the synthesis and secretion of many hormones like insulin. We studied the prevalence of ZnT8 Ab in patients with autoimmune thyroid diseases (AITD).Material and methods: The study was performed in the group consisting of 20 Grav...

Background: Mesoderm-specific transcript (MEST) is an epoxide α/β-hydrolase protein with catalytic activity that is determinant for the development of adipocytes. The MEST gene is an imprinted gene transcribed only from the paternal allele. Although the mechanism by which MEST overexpression augments fat accumulation and storage in adipocytes has not been fully elucidated, frequent subcellular contacts between MEST-positive endoplasmic reticulum, mi...

Background: Growth hormone plays a primary role in stimulating postnatal growth by way of insulin-like growth factor 1 (IGF1) which is produced in the liver in response to GH. A deficiency of GH arrests maturation during childhood, and the stature of such subjects is generally much shorter than the average stature. However, some cases of GH deficiency attain normal stature as adults.Case presentation: A 20 years old man was referred for a further evaluat...

Introduction: Steroidogenic factor-1 (SF1), encoded by the NR5A1 gene, regulates several genes involved in male sexual determination, such as SOX9 and AMH, cholesterol mobilization and synthesis of a number of steroidogenic enzymes, like 3βHSD, and androgen biosynthesis, like INSL3. Mutations in NR5A1 have been associated to a broad phenotypic spectrum in 46, XY subjects, including pure gonadal dysgenesis, infertility, anorchia...

Background: RARβ cooperates with Nur77 to in-vitro regulate HSD3B2 transcription. NUR77 expression parallels HSD3B2 expression with a much lower level in androgen-producing adrenocortical tissues (childhood virilizing adrenocortical tumours (VAT), fetal zone (FeZ) and zona reticularis, ZR). RARβ is down-regulated in starved, hyperandrogenic H295R cells. However, the mechanisms regulating this expression pattern and the relevance of RARβ to huma...
