Introduction: Short stature is frequently caused by SHOX variants causing functional deficiency. SHOX resides in the pseudoautosomal region (PAR1) of the sex chromosomes and SHOX/enhancer alterations result in a broad phenotypic range: from Langer mesomelic dysplasia, Léri-Weill dyschondrosteosis to idiopathic short stature (ISS). Growth hormone (GH) therapy is indicated for those individuals with short stature due to SHOXdeficiency. A frequent limitati...

Background: Good adherence to recombinant human growth hormone (r-hGH) is crucial to achieve optimal growth outcomes in children with GH deficiency (GHD). Controlling factors that negatively impact adherence is difficult in clinical practice. In order to obtain a better understanding of caregiver behaviour, an Argentinian patient support programme (PSP) implemented TuiTek®, a personalised programme comprising behavioural change training, call guides...

Introduction: Since 1960, enlarged polycystic ovaries associated with hypothyroidism, delayed bone age and precocious puberty are recognized as Van Wyk and Grumbach syndrome. Although it is rare entity, it should be considered in differential diagnosis of the enlarged polycystic ovaries.Case: An eleven-year-old girl was presented with sudden onset of abdominal pain and vomiting. A large mass with multiple cysts was seen ...

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases caused by a deficiency of enzymes responsible for the steroidogenesis. The most common cause is 21-hydroxylase deficiency. There are three forms of CAH due to 21-hydroxylase deficiency: the classic form with salt loss, the classic virilizing and the non-classical form. In pediatric age, CAH is most often manifested by masculinization of the genitals of female newborns, adrenal crisis or premature p...

Introduction: Bone fragility or predisposition to fractures with low-impact energy is a rare but potentially limiting condition. Variations in PLS3 gene are a cause of monogenic osteoporosis due to the alteration of osteoclast and osteocyte function and bone mineralization. It is characterized by early-onset osteoporosis, peripheral fractures, vertebral compression fractures and thoracic kyphosis. Due to its X-linked inheritance, the phenotype is more severe i...

Introduction: Signs of hyperandrogenemia are common through adolescent and young females, hirsutism affecting 5% of reproductive -aged women. The most common cause of hyperandrogenemia and insulin resistance (IR) is polycystic ovary syndrome (PCOS) (1). The differential diagnosis includes congenital adrenal hyperplasia (CAH) (2), androgen secreting tumors, but also very rare genetic syndromes of IR.Case report: A 13 year...

Introduction: Short stature is a frequent reason for consultation in the paediatric age group. After appropriate clinical, radiological and laboratory evaluation, up to 60-80% of children are classified as idiopathic short stature (ISS) because no underlying cause can be found. Nowadays, the spreading of molecular is revealing that many of the patients initially classified as TBI, have variants in genes involved in the growth plate development. IHH gene is inv...

Introduction: Overgrowth syndromes comprise an heterogeneous group of rare disorders characterized by generalized or segmental excessive growth commonly associated with additional features, such as developmental delay, visceromegaly and macrocephaly. They may present with inherent health concerns and, in some instances, an increased risk of tumor development requiring prompt diagnosis and appropriate referral.Objective: ...

Introduction: Nephroblastoma or Wilms tumor is the most common pediatric abdominal malignancy. Typically, it is found in children younger than 5 years old, girls being more likely to have Wilms tumor than boys. The etiology of the disease is genetic, due to alteration in the development of the genitourinary tract.[1] Treatment is represented by surgery (unilateral nephrectomy), chemo- and radio-therapy. Paraneoplastic endocrine disorders may occur, but there a...

Background: Congenital hypopituitarism (CH) is a group of disorders characterized by deficiencies in one or more hypophyseal hormones and a marked variability in genotype-phenotype correlations. Central diabetes insipidus (DI) is caused by a decreased release of ADH and results in a variable degree of polyuria. Their association is normally found in congenital cerebral midline abnormalities, such as septo-optic dysplasia.Objectiv...
