Introduction: It is well known that thyroid disease (TD) is more prevalent in patients with Down Syndrome (DS). Among the dysfunctions are congenital hypothyroidism (CH), subclinical hypothyroidism (SC-H), Hashimoto’s thyroiditis (HT) and Graves’ disease (GD).The evaluation of the occurrence of these diseases in patients with DS according to age is still poorly reported.Objective: Verify the prevalence of TD in children and adolescents with DS ...

Aim: To determine Sertoli cell function at diagnosis and after 3 months of chemotherapy.Methods: A prospective cohort study was performed including children with acute lymphoblastic leukaemia, acute myeloid leukaemia, or non-Hodgkin lymphoma. Serum levels of AMH were evaluated at diagnosis and after 3 months during chemotherapy. Results were analysed as standard deviation scores according to pubertal stage and expressed ...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Introduction: Obesity is the main public health problem in Mexico. Several factors have been described as explanations, mainly: increased sedentarism and caloric intake. Such environment has been described as “obesogenic”. The aim of this study was to describe the relationship between the components of such obesogenic environment and the adiposity of Mexican children and adolescents.Methods: We carried a population-based cross-sectional study o...

Background: Most reports on gonadotoxicity associated with chemotherapy of acute lymphoblastic leukemia (ALL) comes from studies in adults, and they are mainly focused on the sensitivity of testicular germ cells. Little attention has been placed on Sertoli cells in prepubertal patients, even though Sertoli cell function is essential for adult spermatogenesis.Objective: To evaluate Sertoli cell function in prepubertal boys who receive chemotherapy for ALL...

Background: Gliomas are the most common subgroup of CNS tumours in children. Histologic grading is a means of predicting the biological behavior of these tumours and survival is strongly correlated with tumour gradation. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, nuclear translocation of the type 1 IGF1R has been demonstrated in tumour tissues. Although the IGF1R expression has been described in C...

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED, OMIM240300) is a rare monogenic disease due to biallelic mutations in the Autoimmune Regulator (AIRE) gene. This encodes for a thymus-enriched transcription factor responsible for central immune tolerance. Classic diagnostic criteria are the presence of two of main symptoms of chronic mucocutaneous candidiasis (CMC), hypoparathyroidism (HP) and Addison’s disease (AD). Non-endocrine autoimmun...

Objectives: To investigate prognostic markers (age, initial hearing level, karyotype, chronic hormonal therapies, and presence/absence of a mid-frequency dip influence) for hearing loss (HL) in Turner syndrome (TS).Design: Longitudinal cross-sectional and retrospective study.Study Population: 61 TS females (age range 4 - 45 yrs), diagnosed by cytogenetic analysis (49,2% monosom...

Background: Autoimmune diseases have a higher incidence and prevalence among the individuals with Down syndrome (DS) compared to chromosomally normal people (increased risk for thyroid, gut and islet autoimmunity, juvenile idiopathic arthritis) These findings provide insights into a very aggressive phenotypic expression of autoimmunity in DS children.Objective and hypotheses: To investigate for the 1st time whether the association with DS might per se mo...
