Introduction: Premature adrenarche refers to appearance of pubic hair and sometimes axillary hair before eight and nine years in girls and boys respectively. The most constant sign is the appearance of pubic/axillary hair. Furthermore, other signs of androgen effect (adult type body odor, acne, greasy hair, accelerated statural growth) are valuable to complete the diagnosis. However, it is important to be mentioned that no virilization signs are associated wit...

Introduction: The prevalence of childhood obesity is increasing worldwide, and the management remains a challenge. The mainstay of management is lifestyle modification but if this is not successful, pharmacological agents are considered although the options in children and young people are quite limited. Metformin has been used as an adjunct therapy alongside lifestyle modification in children and young people with obesity. Some studies have shown it to be eff...

Background: Leptin receptor deficiency leads to severe early-onset obesity and pituitary dysfunction. Here we present the first case of monogenic obesity due to a novel mutation in LEPR gene in Russia.Case report: 16-year-old female patient was admitted to our hospital with morbid obesity and primary amenorrhea. She was born at term with a birth weight of 3360 g to non-consanguineous parents. She had a mild deve...

The pituitary gland is a pea-sized organ located at the base of the brain. It synthesizes, and secretes, many hormones that control growth and development, and the functioning of the other endocrine glands. Panhypopituitarism is a condition of inadequate or absent production of all these hormones. LHX3 (LIM Homeobox 3) is a Protein-Coding gene involved in pituitary development. Mutations in this gene may result in a deficiency of multiple pituitary hormones. Here, we present a...

Objective: To report the clinical and gene mutation characteristics of a patient with lysine urinary protein intolerance (LPI) characterized by lupus nephritis, lupus encephalitis and extreme short stature, so as to improve understanding of the clinical characteristics of LPI caused by SLC7A7 gene mutation.Methods: The clinical manifestation, laboratory examination and gene test results of a child with LPI diagnosed and ...

Introduction: Thyroid nodules occur in 1.8% children which is not so often in comparison to adults (19–68%), but in children they appear to be at higher risk of malignancy (22–26% vs.5–10% respectively). It has been shown that the probability of thyroid nodules malignancy correlates with the presence of characteristic ultrasonographic features. Elastography - the noninvasive ultrasound imaging technique based on estimation of the tissue flexi...

Acrodysostosis (ACRDYS) (MIM 101800) is a rare autosomal dominant condition affecting skeletal growth and resulting in primary skeletal dysplasia. Two types of ACRDYS have been described and characterized by distinct references on OMIM database. ACRDYS is similar and often confused with PHP1A, but caused by mutations downstream of the genes involved in PHP1A. Most of the patients have de novo variants. Both types of ACRDYS present with similar skeletal abnormalities (dispropor...

Managing Graves' disease (GD) should be simple. Stop the immune system from targeting the TSH receptor and the disease is cured. Unfortunately this is not yet feasible in most young people and GD is not a trivial condition for those affected. There are significant advantages and disadvantages of all current treatments with no easy way forwards for many and the family's decisions will reflect their perceptions of medical, radiation and surgical risk. The fact that two o...

Background: Obesity results from interactions between environmental and genetic factors. Despite a relatively high heritability of common, non-syndromic obesity (40–70%), the search for genetic variants contributing to susceptibility has been a challenging task. To date, more than 40 genetic variants have been associated with obesity and fat distribution. However, since these variants do not fully explain the heritability of obesity, other forms of va...

Background: MAS is a rare disorder, this syndrome is classically characterized by a triad of physical signs: cafe-au-lait skin pigmentation(SP), fibrous bone dysplasia(FD), peripheral precocious puberty(PPP). In children, the most frequent initial presentation of MAS is PPP. MAS is caused by postzygotic activating mutations at the R201 codon of the GNAS gene, leading to a state of somatic mosaicium. In MAS patients, the frequency of mutations is expected to be...
