BACKGROUND: Anti-Müllerian hormone (AMH) is produced by granulosa cells surrounding follicles that have undergone recruitment from the primordial follicle pool but have not been selected for dominance (preantral and early antral follicles). In healthy girls, serum levels of AMH vary considerably between individuals. We aimed to evaluate the AMH level in girls with premature thelarche (PT) and central precocious puberty (CPP). METHODS: Girls with CPP (n=21), PT (n=24) and a control prepubertal group (n=22) were included in the study...

STUDY OBJECTIVE: To investigate the potential of serum anti-Müllerian hormone (AMH) and inhibin B (INHB) levels as markers for pubertal progression rate in girls with central precocious puberty (CPP). DESIGN, SETTING, AND PARTICIPANTS, INTERWENTIONS, AND MAIN OUTCOME MEASURES: A total of 148 girls were enrolled, including 65 girls with premature thelarche (PT) and 83 girls with CPP, grouped based on the results of Gonadotropin-releasing hormone (GnRH) stimulation tests. Girls with CPP underwent a six-month follow-up, and were further divided into two subgroups: progressive CPP (P-CPP) group (n=55) and slowly progressive CPP (SP-CPP) group (n=28)...

OBJECTIVE: The aim of the study is to investigate the diagnostic role of kisspeptin and neurokinin B in idiopathic central precocious puberty (ICPP) and premature thelarche (PT). METHODS: The girls who presented with early breast development before the age of 8 years were evaluated. Basal and stimulated FSH, LH levels and basal neurokinin B and kisspeptin levels were measured. Patients who had peak LH > 5mIU/mL, and a bone age (BA) /chronological age (CA) ratio >1...

Clinical and laboratory diagnosis and treatment of central precocious puberty (CPP) remain challenging due to lack of standardization. The aim of this revision was to address the diagnostic and therapeutic features of CPP in Brazil based on relevant international literature and availability of the existing therapies in the country. The diagnosis of CPP is based mainly on clinical and biochemical parameters, and a period of follow-up is desirable to define the "progressive" form of sexual precocity. This occurs due to the broad spectrum of pubertal development, including isolated premature thelarche, constitutional growth and puberty acceleration, progressive and nonprogressive CPP, and early puberty...

BACKGROUND/AIMS: Polybrominated diphenyl ethers (PBDEs) are widely used as flame retardants and have shown endocrine disruption properties in experimental studies. The aim of this study was to investigate the association between the exposure to PBDEs and alterations of puberty in girls referred for idiopathic central precocious puberty (ICPP) and premature thelarche (PT). METHODS: A case-control study was conducted in 124 girls: 37 girls with ICPP (mean age 7.4 ± 0...

BACKGROUND: Premature thelarche (PT) seems to be increasing and it is difficult to differentiate its early stages from precocious puberty (PP). Clinical and biochemical parameters are warranted to differentiate the two diagnoses. METHODS: One hundred ninety-one girls aged 0.5-7 years were included. Diagnoses were validated and the girls were categorized to the groups PP (n = 27) and PT (n = 164). Anthropometry, Tanner stages, ethnicity, bone age, and biochemistry, were recorded...

OBJECTIVE: Kisspeptin levels have been reported in children with premature thelarche, precocious puberty and adolescent gynecomastia, but there are no reports on kisspeptin levels in the neonatal period. This study aimed to investigate plasma kisspeptin hormone levels in newborns with and without breast enlargement. METHODS: Plasma kisspeptin levels and other related biochemical variables were investigated in this prospective study conducted on 40 (20 girls and 20 boys) newborn infants with breast enlargement and on 40 healthy control infants (20 girls and 20 boys)...

PURPOSE: It is difficult to differentiate between central precocious puberty (CPP) and premature thelarche (PT) in girls. The aim of this study was to investigate the diagnostic usefulness of pelvic ultrasonography to distinguish between CPP and PT in girls with early breast development. METHODS: This study included girls with early breast development who visited the clinic between January 2012 and December 2013. Clinical, laboratory, and pelvic ultrasonographic data were evaluated...

BACKGROUND: Multiple congenital melanocytic naevi (CMN) is a rare mosaic RASopathy, caused by postzygotic activating mutations in NRAS. Growth and hormonal disturbances are described in germline RASopathies, but growth and hormone status have not previously been investigated in individuals with CMN. OBJECTIVES: To explore premature thelarche, undescended testes, and a clinically abnormal fat distribution with CMN through prospective endocrinological assessment of a cohort of subjects with CMN, and a retrospective review of longitudinal growth of a larger group of patients with CMN from outpatient clinics (which included all subjects in the endocrinological assessment group)...

BACKGROUND: The possible difference of antimüllerian hormone (AMH) levels at central precocious puberty (CPP) and premature thelarche (PT) has not been properly evaluated. OBJECTIVE/HYPOTHESIS: By evaluating AMH levels in girls with diagnosed CPP and PT, we aim to show the change of AMH levels at the pubertal onset. SUBJECTS: Sixty-five girls who have breast development before the age of 8 years and 25 healthy girls were enrolled in the study...

The aim of this study was to explore the significance of plasma kisspeptin levels in diagnosis and therapeutic evaluation through the analysis of the kisspeptin levels of girls diagnosed with idiopathic central precocious puberty (ICPP) prior to treatment and after 6-months of treatment and those with simple premature thelarche (PT). A total of 70 girls including 24 girls diagnosed with ICPP, 21 girls with PT and 25 normal girls were enrolled in the study. ELISA analysis was conducted to detect the plasma levels of kisspeptin...

BACKGROUND: Signs of puberty in very young children are often benign, but the evaluation needed and follow-up are controversial. OBJECTIVES: The study had three objectives: 1) to analyze the frequency of diagnoses in children <3 years referred for early puberty; 2) to examine the usefulness of lab testing; and 3) to identify red flags indicating a more serious diagnosis. METHODS: Charts of all children younger than age 3 referred for early puberty between 7/09 and 6/13 were reviewed...

AIM: We aimed to investigate serum nesfatin-1 level in girls with premature thelarche (PT) and its relationship with anthropometric parameters and leptin, which are involved in the initiation of pubertal process. SUBJECTS-METHODS: Non-obese girls who presented with the complaint of early (2-8 years) and isolated breast development were included in the study. The control group consisted of age-matched healthy prepubertal girls. Auxological measurements were performed in all subjects...

OBJECTIVE: Idiopathic premature adrenarche (PA) refers to presence of androgenic signs before the age of eight years in girls in the absence of thelarche. In children with PA, increased adrenal androgens lead to changes in body composition and transient growth acceleration. Although the association between PA and some components of the metabolic syndrome is well known, body composition has not been extensively studied in these patients. METHODS: We examined 47 girls with PA with a median age of 7...

OBJECTIVE. We analyzed the correlation between breast development and ultrasound-measured breast bud diameter. We also evaluated different breast ultrasound findings in pediatric subjects with precocious puberty and premature thelarche while comparing bone age and hormone levels. MATERIALS AND METHODS. We performed a retrospective study with a sample of 90 girls (mean age, 7.8 years) who underwent breast ultrasound for evaluation of early breast development between March 2011 and February 2013. We evaluated breast ultrasound grade, bud diameter, and clinical characteristics including bone age and hormone levels...

The aim of the present study was to investigate the diagnostic role of serum neurokinin B level and its relationship with kisspeptin and leptin, which are known to be involved in the initiation of pubertal process. Girls who presented with breast development (<8 years) were included in the study. All patients underwent bone age assessment. Basal levels of serum follicle stimulating hormone and luteinizing hormone were measured and gonadotropin releasing hormone stimulation test was performed. Patients with a bone age/chronological age ratio >1 and a peak luteinizing hormone response in gonadotropin releasing hormone stimulation test >5mIU/L were included in the central precocious puberty group, while patients who did not meet these criteria were included in the premature thelarche group...
