Peripheral Precocious Puberty in girls affected by McCune-Albright Syndrome: safety and efficacy retrospective study on letrozole treatment

Tessaris Daniele , Gazzin Andrea , Bonino Elisa , Tuli Gerdi , Matarazzo Patrizia , de Sanctis Luisa ,

Introduction: Precocious Peripheral Puberty (PPP) due to autonomous ovarian activation is the most frequent endocrinopathy in girls with McCune-Albright Syndrome (MAS). Main goals of treatment for PPP are to reduce signs of estrogen exposure, also improving final height, and mitigate secondary psychological influence of sexual hormones exposure. This retrospective study analyzes the long-term safety and efficacy of letrozole treatment in a cohort of girls with...

Co-occurrence of Turner (46,X-ring/45,X0 mosaicism) and Mayer-Rokitansky-Kuster-Hauser Syndromes: a case report

Ocello Laura , Ramponi Giulia , Maitz Silvia , Marco Santo Di , Adavastro Marta , Biondi Andrea , Cattoni Alessandro ,

Introduction: The co-occurrence of Turner Syndrome (TS) and Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKHS) has been rarely described in literature. The resulting clinical picture includes congenital aplasia of the uterus and of the upper two-thirds of the vagina and ovarian dysgenesis.Case Report: We hereby report the case of a 14-year-old girl referred to our endocrine outpatient clinic for pubertal delay. Her previous medical history ...

Gonadotropin Flare with Different Depot GnRH Agonists: Comparative Analysis.

Freire Analia , Arcari Andrea , Gabriela Ballerini Maria , Ignacio Bergada , Gabriela Ropelato Maria , Gryngarten Mirta ,

Central precocious puberty (CPP) is effectively treated by inhibition of GnRH signaling through GnRH receptor desensitization with depot GnRH agonists (dGnRHa), but the first injection is associated with a surge in LH and FSH (flare) that proportionally increases estradiol levels. When estradiol levels drop, usually within a fortnight, vaginal bleeding may be seen in a small number of girls. Although dGnRHa that use higher, longer-acting doses are increasingly being used in gi...

Clinical and laboratory characteristics in children with growth hormone deficiency (GHD) and short stature unresponsive to stimulation tests (SUS)

Dalla Bona Eva , Andrea Lanzetta Maria , Tamaro Gianluca , Faleschini Elena , Tornese Gianuca

Background: It has been previously proposed that not all children with short stature displaying an inadequate response to tests for growth hormone (GH) secretion truly suffer from GH deficiency (GHD). Instead, amongst these, solely children with an identifiable monogenic cause of GHD or an identifiable functional or anatomical anomaly in the hypothalamic-pituitary axis should be considered GHD. The remaining patients should be defined as affected by “sho...

Long-Term Effect of Gonadotropin-Releasing Hormone Analogue Therapy on Adult Height in Girls with Central Precocious Puberty Diagnosed before 4 Years of Age

Freire Analía , Gryngarten Mirta , Gabriela Ballerini María , Vieites Ana , Gabriela Ropelato María , Arcari Andrea

Background: Central precocious puberty (CPP) is uncommon before the age of 4 and treatment with GnRH analogues have shown unequivocal benefits. CPP during or near mini puberty entails differential clinical and biochemical features in the diagnosis and leads to longer treatment and follow-up. There are very limited studies with long-term outcomes about CPP girls exclusively < 4 years of age regarding growth, menarche, and adult height after GnRHa withdrawal....

Hypophosphatasia: a pediatric patient treated with asfotase alfa

Orlandini Eleonora , Schiavariello Concetta , Tamburrino Federica , Perri Annamaria , Mazzanti Laura , Pession Andrea , Scarano Emanuela

We describe a 5 years-old patient referred to our centre for dysmorphic features and delayed psychomotor development. Negative family history, second child, full-term birth, eutocic delivery, regular growth parameters at birth and neonatal adaptation. Autonomous walking at 20 months with clumsiness; first words at 2 years with dysarthria and dysphagia. Brain MRI and array-CGH were normal. At the neurological examination: perioral hypotonia, sialorrhea, praxic difficulties. At ...

Schaaf-Yang syndrome: Report of two cases

Rampi Gabriela , Berger Malena , Cecchi Griselda , Schneider Claudia , Juarez Peñalva Sofia , Forrester Andrea

Schaaf-Yang syndrome (SYS) is a genetic disorder caused by truncating pathogenic variants in the paternal allele of the maternally imprinted, paternally expressed gene MAGEL2, located in the Prader-Willi critical region 15q11-15q13. SYS is a neurodevelopmental disorder that has clinical overlap with Prader-Willi Syndrome in the initial stages of life, being the intellectual disability, developmental delay, autism spectrum disorder, neonatal hypotonia, infantile feeding problem...

Congenital Generalized Lipodystrophy in Down Syndrome patient

Soledad Reinoso Andrea , Ricci Jaime , Pietropaolo Guadalupe , Balbi Viviana , Morin Analia

Introduction: Lipodystrophy syndromes are rare heterogeneous disorders characterized by deficiency of adipose tissue, usually a decrease in leptin levels and, frequently, severe metabolic abnormalities including diabetes and dyslipidemia. Congenital Generalized Lipodystrophy is a rare autosomal recessive genetic desease that presents early, at birth or just after. The estimated prevalence ranges from 1 in a millon to 1 in 10 millon individual...

The Loeys-Dietz-Syndrome is a connective tissue disease, which belongs to the group of Marfanoid syndromes. LDS is classified into 6 different subtypes according to the underlying mutation. All mutations are autosomal dominant inherited. Patients with Loeys-Dietz-Syndromes are characterized from cardiovascular and skeletal malformations, like aneurysms of aorta and other arteries, pectus excavatum, pectus carinatum, chicken- or funnel breast, arachnodactyly clubfoot, scoliosis...

Three cases of rare bone dysplasias

Tvrda Petra , Lacik Michal , Porubova Petra , Plevova Pavlina , Hladikova Andrea , Grecmalova Dagmar

Introduction: Bone dysplasias are a group of disorders affecting the development and growth of bones and cartilage. These conditions can lead to various skeletal abnormalities, including short stature, deformities and problems with joint function. Skeletal dysplasias are generally caused by genetic mutations. There are over 400 different types of bone dysplasias, each with its specific set of symptoms and genetic causes. This study introduces three patient cas...
