Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age, and is characterised by chronic inflammation and in most cases by insulin resistance besides ovulatory dysfunction and hyperandrogenism. HMGB1 is a small protein with cytokine activity that can activate nuclear factor kappa light chain enhancer of activated B cells (Nf-kB), and signals through the Receptor for advanced glycation end products (RAGEs) and through the T...

Psychological changes in youth with diabetes: comparison between preadolescents and adolescents

Longaretti Roberta , Pozzi Clara , Trezzi Cecilia , Achutegui Irune , Docente Chiara , Langone Marta , Favalli Valeria , Frontino Giulio , Rigamonti Andrea , Di Tonno Raffaella , Bonfanti Riccardo ,

Background: The course of type one diabetic disease (T1DM) varies according to the period of life and in response to various external or internal factors. Adolescence is an evolutionary phase that involves important developmental changes and identity construction. Diabetes disease and its management, especially in this life period, can lead to psychological distress and impact on Self-redefinition.Method: We conducted a ...

Background: Central precocious puberty (CPP) results from premature activation of hypothalamic-pituitary-gonadal axis, which leads to an increased release of gonadotropin-releasing hormone (GnRH). GnRH stimulates the development of secondary sexual features, rapid bone maturation and growth. GnRH agonists (GnRHa) represent the gold-standard therapy in CPP children and their use is responsible for pituitary GnRH receptors down-regulation, luteinizing hormone (L...

Mosaic variegated aneuploidy (MVA) syndrome represents a rare autosomal recessive disease characterized by aneuploidies with gain and loss of multiple chromosomes. We describe case of two Moroccan brothers with MVA2, due to CEP57 mutations. Patients are 17 and 13-year-old male siblings of a Moroccan healthy consanguineous couple. Oldest brother was delivered at 35 gestational weeks after IGR diagnosis, small for gestational age (SGA, 1300 grams, -3 SDS). Younger patient’...

During the COVID-19 pandemic, a significant increase in Central Precocious Puberty(CPP) has been observed worldwide. The reasons for this phenomenon are yet unclear. In order to evaluate if fear, stress and coping strategies used by children and parents when dealing with negative emotional situations and health issues might have acted as triggers for this phenomenon, we administered specific questionnaires to girls who had a diagnosis of CPP before and after the COVID-19 relat...

Six-year-old female, diagnosed with GH deficiency at another Center (H: -3.13SDS; H peak with clonidine 5.7ng/mL, with insulin 1.2ng/mL). Brain MRI at diagnosis: small pituitary gland, ectopic neurohypophysis, normal stalk, right internal carotid artery aplasia. At 10 years onset of polyuria-polydipsia syndrome (PPS) (4L/day–154ml/kg/die); mood disorders and ADHD diagnosis were also reported. A fluid deprivation test was performed, lasting 22 hours (pre: S-Osm 275mOsm/L,...

Background: Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder among women of reproductive age and is characterised by chronic low-grade inflammation, ovulatory dysfunction and hyperandrogenism, and often by insulin resistance. The IGF system is involved in glucose metabolism regulation and is altered in chronic inflammation where both IGF-I and –II can be reduced. We previously described increased HMGB1 content in follicular fluid (FF) in P...

Comparison of clinical features, therapy, and disease evolution in a population of children and adolescents with Graves' disease and Type 1 Diabetes compared to Graves' disease alone.

Introduction: About 25% of children and adolescents with Type 1 Diabetes (T1D) have one or more associated autoimmune conditions. Although Graves' disease (GD) rarely occurs, considering the potential severity of manifestations, an early diagnosis and appropriate treatment are essential. The first line treatment is methimazole, whose use is not free from side effects; therefore, it is important to start with the most appropriate dosage.<p class="abste...

Although craniopharyngiomas are low-grade tumours, long-term survivors frequently suffer from severe morbidity due to hypothalamic lesions, such as hypothalamic obesity, that is largely resistant to lifestyle modification and pharmacotherapy. We investigated the efficacy of bariatric surgery in two patients with craniopharyngioma-related hypothalamic obesity during 18 months of follow-up. Patient n1, diagnosed with craniopharyngioma and treated with complete surgical excision ...

A 5-years-old boy was admitted because of polydipsia and polyuria. His family history was unremarkable. After water deprivation test (10h), laboratory test showed high levels of serum sodium (150.1 mmol/L), low urine osmolarity (88 mOsm/kg) and high serum osmolarity (301 mOsm/kg) consistent with the diagnosis of central diabetes insipidus (CDI). He started therapy with oral desmopressin with clinical improvement. Brain MRI revealed pituitary stalk thickening (3 mm), no hyperin...
