Hypothalamic hamartomas (HH) are rare congenital malformations located in the region of the tuber cinereum and third ventricle. Their usual clinical presentation is characterized by gelastic/dacrystic seizures which often become pharmaco-resistant and progress to secondary focal/generalized intractable epilepsy causing mostly in children cognitive and behavioral problems (particularly in cases of progressive epileptic encephalopathy) and precocious puberty. Whereas gelastic seizures can be surgically controlled either by resection of the lesion or disconnection (tissue-destructive) procedures, aimed at functionally prevent the spreading of the epileptic burst; generalized seizures tend to respond better to HH excision rather than isolated neocortical resections, which generally fail to control them...

Central precocious puberty (CPP) is caused by premature activation of the hypothalamic-gonadal axis, and must be treated adequately. In particular, CPP that occurs at a relatively young age or in boys is likely to be caused by an organic lesion. Hypothalamic hamartoma (HH) is the most common organic cause of CPP. The present case report describes an 11-month-old female infant who presented with vaginal bleeding and rapidly progressive secondary sex characteristics from the age of 6 months. She was diagnosed with CPP following the detection of HH via magnetic resonance imaging...

PURPOSE: The effects of gonadotropin-releasing hormone agonist (GnRHa) treatment on the energy metabolism in girls with central precocious puberty (CPP) are controversial. We focused the changes and related factors of serum levels of leptin and adiponectin in girls with CPP before and during GnRHa treatment. METHODS: Thirty girls with idiopathic CPP were enrolled in the study. Their auxological data and fasting blood were collected at the baseline and after six months of GnRHa treatment...

BACKGROUND AND OBJECTIVES: Patients with central precocious puberty (CPP) may have increased serum leptin levels; however, it is not well known whether this increase differs between patients with and without obesity. Our objectives were to describe the changes in serum leptin in girls with CPP in the first 12 months after diagnosis based on BMI and to explore whether serum leptin level at CPP diagnosis is related to BMI z-score (BMIz) after a one-year follow-up. DESIGN: A prospective cohort study was performed...

Few studies have investigated the long-term effects of gonadotropin-releasing hormone (GnRH) agonist treatment on the reproductive function of central precocious puberty (CPP) girls. In this cross-sectional study, we assessed the ovarian function by analyzing the serum anti-Müllerian hormone (AMH) levels of CPP girls. Our study included 505 CPP girls subdivided into 5 groups according to the GnRH agonist treatment stage: group A (before treatment, n = 98), group B (3 months after initiation, n = 103), group C (12 months after initiation, n = 101), group D (24 months after initiation, n = 101), and group E (6 months after discontinuation, n = 102)...

With an estimated prevalence of 1 in 100 000 births, 11β-hydroxylase deficiency is the second most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in CYP11B1 Clinical features include virilization, early gonadotropin-independent precocious puberty, hypertension, and reduced stature. The current mainstay of management is with glucocorticoids to replace deficient steroids and to minimize adrenal sex hormone overproduction, thus preventing virilization and optimizing growth. We report a patient with CAH who had been suboptimally treated and presented to us at 6 years of age with precocious puberty, hypertension, tall stature, advanced bone age, and a predicted final height of 150 cm...

We present a female child with Peutz-Jeghers syndrome (PJS) with a recurrent ovarian Sertoli-Leydig cell tumor (SLCT). SLCTs are relatively rare sex cord neoplasms that can occur in PJS. The patient was an African-American female who first presented at the age of 3 years with precocious puberty, and then at the age of 17 years with abdominal pain and irregular menses. In each case, she had resection of the mass, which included oophorectomy. To our knowledge, this is the first reported case in a child with PJS to have a recurrent ovarian SLCT...

BACKGROUND: Ovarian tumors are uncommon in childhood and constitute around 1% of childhood malignancies. Two thirds of pediatric ovarian tumors are germ cell tumors. Epithelial ovarian tumors and stromal tumors are less frequent. We share our experience in childhood ovarian cancers, analyzing a series of cases with respect to the clinical profile, treatment and survival. METHODS: All newly diagnosed ovarian tumors in children up to 14 years of age, registered in our Pediatric Oncology Division between January 2000 and December 2009 were retrospectively reviewed...

Van Wyk-Grumbach syndrome (VWGS) is a rare complication of prolonged untreated juvenile hypothyroidism characterized by precocious puberty and enlarged multicystic ovaries. A 13-year-old girl visited our outpatient clinic due to menstrual irregularities. She had precocious puberty, pituitary hyperplasia and multiple cystic ovaries in addition to clinical signs of severe congenital hypothyroidism. After the initiation of L-thyroxine therapy, the symptoms were alleviated in a short time. This rare syndrome is easy to be misdiagnosed as pituitary and ovarian tumor...

Dental maturity is associated with skeletal maturity, which is advanced in girls with central precocious puberty (CPP). We investigated the performance of dental maturity as a screening method for CPP using mandibular second premolar and molar calcification stages, assessed the associated anthropometric and laboratory factors, and evaluated pubertal response predictors using the gonadotropin-releasing hormone stimulation test (GnRHST) in prepubertal and pubertal girls. A prospective case-control study was conducted in girls, aged 7...

Purpose To evaluate the prevalence of, and risk factors for, early endocrine disorders in childhood brain tumor survivors (CBTS). Patients and Methods This nationwide study cohort consisted of 718 CBTS who were diagnosed between 2002 and 2012, and who survived ≥ 2 years after diagnosis. Patients with craniopharyngeoma or a pituitary gland tumor were excluded. Results of all endocrine investigations, which were performed at diagnosis and during follow-up, were collected from patient charts. Multivariable logistic regression was used to study associations between demographic and tumor- and treatment-related variables and the prevalence of early endocrine disorders...

Chronic gonadotropin-releasing hormone agonist (GnRHa) administration is used where suppression of hypothalamic-pituitary-gonadal axis activity is beneficial, such as steroid-dependent cancers, early onset gender dysphoria, central precocious puberty and as a reversible contraceptive in veterinary medicine. GnRH receptors, however, are expressed outside the reproductive axis, e.g. brain areas such as the hippocampus which is crucial for learning and memory processes. Previous work, using an ovine model, has demonstrated that long-term spatial memory is reduced in adult rams (45 weeks of age), following peripubertal blockade of GnRH signaling (GnRHa: goserelin acetate), and this was independent of the associated loss of gonadal steroid signaling...
