Objective: The development of specific growth charts for Turner Syndrome (TS) promotes adequate assessment of growth and weight gain, and earlier diagnosis of comorbidities, and may help to analyze the effectiveness of treatments to promote growth and puberty. The aim of this study was to construct a growth chart with the largest possible series of patients with a cytogenetic diagnosis of TS from a Brazilian reference center.
Methods: This is a longitudinal study, with 259 cases of TS born between 1957 and 2014 and followed between 1975 and 2019, without the use of GH or oxandrolone.

Objective: Considering the rarity and clinical and molecular diversity of Wolfram syndrome (WS), the objective of this study was to identify patients with a clinical presentation suggestive of WS following up at a single Brazilian diabetes service and analyze their clinical and molecular characteristics.
Subjects And Methods: The study included all patients with a clinical presentation of WS following up between 1991 and 2022 with early-onset diabetes mellitus and other WS signs and symptoms. A retrospective analysis was conducted, including patients' age, sex, consanguinity, age at symptom onset, diagnosis of diabetes mellitus, optic atrophy, diabetes insipidus, neurological and psychiatric disorders, hearing loss, urinary disorders, hypogonadism, and molecular analysis.

Adrenal hypoplasia congenita, attributed to NR0B1 pathogenic variants, accounts for more than 50% of the incidence of primary adrenal insufficiency in children. Although more than 250 different deleterious variations have been described, no genotype-phenotype correlation has been defined to date. We report a case of an adopted boy who reported the onset of an adrenal crisis at 2 weeks of age, requiring replacement therapy with mineralocorticoids and glucocorticoids for 4 months.

Objective: Herein, we compared ambulatory blood pressure (ABP) between young adults with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase enzyme (21OHase) deficiency and a control group. Additionally, we analyzed correlations between the glucocorticoid dose and androgen levels and ABP parameters.
Subjects And Methods: This case-control study included 18 patients (6 males and 12 females) and 19 controls (8 males and 11 females) matched by age (18-31 years).
Unlabelled: It is of great importance to investigate any potential detrimental effect on bone health in young adults with 21-hydroxylase enzyme deficiency undergoing glucocorticoid replacement therapy. This study demonstrated normal bone health in well-controlled patients. Additionally, glucocorticoid dose may play an important role in the mineral density of femoral neck region.

We aimed to evaluate myocardial function, vascular structures and epicardial fat thickness in young adults with CAH as a result of 21OHase deficiency. Correlations between the duration and dose of glucocorticoid therapy and cardiovascular parameters were analysed.

Insulin resistance and hyperinsulinemia have been described in CAH patients, whereas the prevalence of overt type 2 diabetes is not higher in CAH than in normal population.

We also verified independent associations of treatment duration and daily hydrocortisone dose equivalent (HDE) with lipid profile within patients. This case-control study included 23 patients (7 male and 16 female) matched by an age range of young adults (18-31 years) with 20 control subjects (8 male and 12 female).

This case-control study comprised 29 post-pubertal 21-OH CAH patients regularly followed at the University of Campinas. Elevated serum 17-hydroxyprogesterone and gene molecular analysis confirmed the diagnosis.

The objective of the present study was to compare HRQoL in the TS and control group, using components and domains of the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). Observational, descriptive, and cross-sectional study with 44 women with TS aged between 18 and 30 years (TS group) and 44 healthy women of the same age which were sisters, relatives, or friends of the TS group (control group).

Methods: An electronic bibliographic search was conducted through the PubMed, Embase, Bireme, Scopus, and Web of Science databases. The main terms were "Quality of Life" and "Turner syndrome.
Background: Ultrasensitive assays to measure pre-pubertal gonadotropins levels could help identify patients with Turner syndrome (TS) in mid-childhood, but studies in this field are scarce. The aim of this study was to analyze gonadotropins levels in girls with TS throughout childhood.
Methods: Retrospective longitudinal study conducted with 15 girls with TS diagnosed with < 5 years whose FSH and LH measures were available since then.

Background: Permanent neonatal diabetes mellitus (PNDM) is a rare disorder, characterized by uncontrolled hyperglycemia diagnosed during the first 6 months of life. In general, PNDM has a genetic origin and most frequently it results from heterozygous mutations in KCNJ11, INS and ABCC8 genes. Homozygous or compound heterozygous inactivating mutations in GCK gene as cause of PNDM are rare.

To date, it is unknown what factors are involved in this metabolic process, even though it is recognized that TS patients are frequently born small-for-gestational age. The aim of this study was to evaluate the correlation between lipid and glucose profiles with being overweight and birth weight and length in TS patients.

The aim of this study was to evaluate the physical measurements and body composition of female patients with the classic form of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. Twenty-eight girls with CAH were classified according to both hormonal control (well or not well controlled) and the clinical form of the disease (simple virilizing or salt-wasting). In the control group, 112 healthy individuals were included, divided into two subgroups (male and female).

The apparent mineralocorticoid excess syndrome (AME) is a rare autosomal recessive disorder due to the deficiency of 11beta-hydroxysteroid dehydrogenase type 2 enzyme (11beta-HSD2). The 11beta-HSD2 enzyme, encoded by HSD11B2 gene, metabolizes active cortisol in cortisone. Mutations on HSD11B2 gene affect the enzyme activity by leading to an excess of cortisol, which causes its inappropriate access to mineralocorticoid receptor.

Short stature is the main factor of emotional impact in girls and women with Turner's syndrome (TS). Growth hormone, alone or associated with sex steroids, allows better adult height. The results of spontaneous final height (FH) in TS can help to evaluate the real cost-benefit of any treatment to improve FH in patients from the same population.
