Objective: Central precocious puberty (CPP) is a common condition in pediatric endocrinology practice. Gonadotropin-releasing hormone agonists (GnRHa) treatment is safe, but the real effect on final height and the ideal timing for treatment remains controversial. The purpose of the authors was to evaluate a nationwide representative group of CPP Portuguese girls treated with GnRHa, assess the effectiveness of treatment and the growth outcome before and after 8...

Introduction: Hereditary causes of rickets often take longer to be diagnosed because they are not very frequent. 1α-hydroxylase alteration is the most frequent vitamin D-dependent rickets. A delay in the treatment associated to a late diagnosis generates an abrupt parathormone deficiency. When initiating treatment, these patients have a risk of hungry bone syndrome.Case: 2-year-8-month-old male patient, with a history of psychomotor...

Summary Answer: Most primordial/primary oocytes were found to have a 46,XX karyotype. Chromosome patterns of the ovarian cells were different from that observed in other tissues.Background: TS is a chromosomal condition associated with partial or complete absence of one of the two X-chromosomes. Females with TS have a limited reproductive lifespan due to an accelerated loss of germ cells. It has been hypothesized that vi...

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Background: Congenital adrenal hyperplasia (CAH), due to 21-hydroxylase deficiency is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000, and even more common in some populations. Do carriers have a survival advantage?Objective and hypotheses: The HPA axis has been reported to be more active in CYP21A2 carriers, and possibly enable a more rapid return to homeostasis. A compensatory increase in CRH s...

Background: Previous studies evaluating bone quality and microarchitecture in X-linked hypophosphatemic rickets (XLH) have produced conflicting data.Objective and hypotheses: To evaluate the bone mineral density (BMD) and microarchitecture in 36 XLH patients (13 children and 23 adults) with confirmed PHEX mutations compared to healthy controls.Method: The areal BMD (aBMD) at lumbar spine (L1-L4), femoral neck, total hip an...

Background: Loss-of-function of immunoglobulin superfamily, member 1 (IGSF1) causes an x-linked syndrome of central hypothyroidism, macroorchidism, delayed pubertal testosterone rise, variable prolactin deficiency, and variable partial growth hormone deficiency in childhood. The clinical features and gene expression pattern suggest a pivotal role for IGSF1 in the pituitary, but detailed knowledge on pituitary hormone secretion in this syndrome is lacking.<p class=...

Introduction: X-linked hypophosphatemic rickets (XLH) is characterized by a mineralization disorder in the growth plate and cortical and trabecular bones, resulting in bone deformities with anthropometric changes and potential alterations in body composition.Objective: To evaluate the body composition of 12 children and adolescents with XLH compared to healthy controls by anthropometric and densitometry data.<p class...

Background: Neonatal TSH screening program for congenital hypothyroidism (CH) in Central Serbia was introduced in 1983. Over the past three decades, increasing overall incidence rate of children with both permanent and transient forms of CH has been observed.Objective and hypotheses: The aim of the study was to compare incidence of CH in the first 16 years of screening (period 1) with the last 15 years of screening (period 2). We also investigated the im...

Background: There are a lot of reasons for missing the diagnosis in neonatal screening for congenital hypothyroidism (CH), but errors in processing samples and reporting results are the most frequent! In Central Serbia screening for CH was instituted in 1983 by determination of the TSH level in dried filter-paper blood spots. All samples are analyzed at one central laboratory. The average number of specimens that are annually screened is 50 000. The screening process was divid...
