Background: Gonadotropin releasing hormone (GnRH)-secretion is not only regulated by neuronal factors but also by astroglia cells via growth factors (transforming growth factor α (TGFα), neuregulin (NRG)), prostaglandin E2 (PGE2) and the erbB receptor family. Mutations of TGFα and erbB1 result in an impaired reproductive capacity. Mice show a characteristically skin phenotype with wavy hair and curly whiskers. The rat strain SPRD-Cu3 (curly) shows a sim...

Objective: Dental plaque removal is an important factor in preventing periodontal diseases and caries. Tooth brushing remains the most reliable method of controlling dental plaque. The purpose of this study was to compare the effectiveness of plaque control performed with a battery powered and manual toothbrushes in over-weight adolescents.Materials and methods: The twenty two adolesents with over-weight were attended in this study. These patients were d...

Background: Congenital hypogonadotropic hypogonadism (HH) is a rare but clinically and genetically heterogeneous disease characterized by an absent or incomplete puberty and infertility. The association of HH with hyposmia or anosmia is defined as Kallmann syndrome. Molecular genetic testing of HH is valuable, as it can prompt the treatment in adolescence.Objective and hypotheses: To identify causative variants in genes associated with HH in a cohort of ...

Puberty is under the precise control of sophisticated regulatory networks, which integrate a large number of endogenous and environmental signals, including metabolic and nutritional cues. Thus, puberty onset is tightly bound to the state of body energy reserves, and deregulation of energy/metabolic homeostasis is often associated with alterations in the timing of puberty. However, despite recent progress in the field, our knowledge of the specific signals and central molecula...

Puberty, as the developmental continuum between infancy and adulthood, is a complex maturational transition, affecting different body systems, which is under the control of sophisticated regulatory networks. Concerning the pubertal awakening of the reproductive axis, much has been learnt in the last decades on the central mechanisms whereby puberty onset is driven. However, most of the information so far available is limited to the roles of specific neurotransmitters and their...

Introduction: The MODY diabetes (Maturity Onset Diabetes of the Young) belongs to monogenic alterations group, the mutation of the gene HNF-1α is the most common and present an autosomal dominant inheritance that causes dysfunction of the Beta pancreatic cell and alteration in the reabsorption of glucose to renal level, with age of variable presentations, it often leads to a misdiagnosis as type 1 diabetes mellitus.Description of the clinical case: ...

The pathological low stature is considered to be one that does not conform to normality (<2 SDS), that with a pathological growth rate. An obvious element is the conditioning that can generate in their professional outings, both in public and private activity. This seems to be evident in the female sex than in the male sex. The health system considers the treatment (with Ghrh) in pathological size without considering sexual dimorphism.Goals: To study...

Background: As well as acting on longitudinal growth, growth hormone (GH) also has a number of metabolic effects, and is involved in the regulation, functioning and development of the immune system.Aims: To evaluate the immune profile in GH-deficient children after 6 months’ GH treatment.Method: A total of 44 children were examined before and after a six-month course of treatment with rhGH (0.03 mg/Kg per day). Levels of IGF1 ...

Background: Skeletal maturation is the most reliable indicator of biological age in children and adolescents. The evaluation of hand and wrist X-Ray according to Tanner-Whitehouse (TW3) or Greulich-Pyle (GP) are the most commonly used methods for biological age assessment. Automated bone age assessment has recently become increasingly popular, however a large independent study comparing automated and manual evaluation of bone age is still missing. The aim of this study was to ...

Introduction: Premature adrenarche (PA) is usually define as the appearance of clinical signs of androgen action before the age of 8 years in girls and 9 years in boys, associated the serum DHEAS above 40µg/dl.Aims: 1) To characterize a population of prepubertal children with PA regarding birth weight, anthropometry, growth velocity, height difference, bone age, IGF1 and DHEAS. 2) To compare IgF1, bone age, growth v...
