Blood cytology in children with down syndrome.

Introduction: Down syndrome is associated with various congenital anomalies and metabolic alterations such as hematological alterations. Values for the major hematological indicators vary with age and sex, but these values have not been described for Mexican children with Down syndrome.

Growth charts for Mexican children with Down syndrome.

We present the results of a prospective, observational, descriptive, cross-sectional study performed on a Mexican population of 1867 children, aged 0-18 years, with Down syndrome (DS), observed between 2013 and 2019. A total of 9968 measurements of height, weight, and head circumference, as well as calculation of body mass index (BMI) were used to create growth charts and tables of percentiles. Growth curves were elaborated using Cole's LMS method.

Lipid profile of Mexican children with Down syndrome.

Introduction: Down syndrome (DS) is associated with various congenital anomalies and metabolic alterations, such as dyslipidemias, that can lead to cardiovascular disease in adulthood. This study was designed to describe the lipid concentrations and the frequency of dyslipidemias in children with DS.

Materials And Methods: The sample included 386 patients, 52.
