Background: Paediatric pituitary adenomas comprise rare but challenging pathologies in children and adolescents related to their endocrine and neurological characteristics.Objective and Hypotheses: We aimed to describe a case report of growth hormone (GH)-secreting pituitary adenoma apoplexy.Method: a 11-year-old girl presented with fever, sudden headache with vomiting. She abruptl...

Backround: Craniopharingiomas are rare embryogenic malformations of the sellar and parasellar region with slow growth and high local recurrence rate. Due to their unfavorauble location, presurgical hypothalamic involvement and treatment-related hypothalamic damage is frequent and lead to hypothalamic syndrome.Objective: we compare weigh gain and growth pattern regarding to hypothalamic involvement of pediatric patients a...

Objective: There is no agreement about which index of adiposity and/or body composition is the most accurate in identifying the metabolic syndrome (METS). The aim of our study was to compare the accuracy of the different indexes in order to recognize the most reliable.Study Design: We evaluated 1332 obese children and adolescents (778 females and 554 males), aged 14.4 ± 1.8 yrs., Body Mass Index (BMI) standard devia...

Background: Obesity is usually correlated with a higher prevalence of 25OH vitamin D (25OHD) deficiency. This might be due to either volumetric dilution of vitamin D in the large fat mass or its increased uptake by adipose tissue. To our knowledge, a systematic study on 25OHD levels in Prader-Willi syndrome (PWS), a genetic disorder associated with severe obesity, is not available.Objective and hypotheses: To analyze the 25OHD values in a population of p...

Background: Adult subjects with Prader-Willi Syndrome (PWS) have low Bone Mineral Density (BMD) and are at risk of osteoporosis. Several observations suggest that peak bone mass is usually achieved by late adolescence, in the presence of adequate gonadal hormone concentrations. Consequently, the altered bone characteristics of PWS patients may be related to inadequate sex steroid levels during pubertal development.Aim: To investigate BMD in PWS females d...

Background: Prader Willi syndrome (PWS) results from the loss of paternally imprinted genes on chromosome 15q11–15 and is characterized by neonatal hypotonia, short stature, hypogonadism, aggressive food-seeking behavior, hyperphagia, and obesity with difficult in losing weight only with nutritional approach.Objective and hypotheses: We report our experience on sleeve gastrectomy in PWS and obese subjects during 12 months of follow-...

Background: Mild TSH elevations are frequently observed in obese patients, in the absence of any detectable thyroid disease.Aims and objective: To evaluate possible causes for the raised TSH levels and to verify possible biochemical and clinical consequences of this condition.Methods: We evaluated 779 (325 males/454 females) obese children, chronological age 14.38±2.56 (range 5.25 to 18.50), height SDS 0.27±1.04 (range &#...

Congenital Central Hypothyroidism (CeH) is a rare and heterogenous disease that can be part of a combined pituitary hormone deficit (CPHD) condition. The immunoglobulin superfamily member 1 (IGSF1) is the gene more frequently involved in these inherited forms and responsible for the so called X-linked IGSF1 deficiency syndrome, characterized by an estimated incidence of 1: 100.000. The main features are CeH, delayed/disharmonic pubertal development, macroorchidism, va...

Hypothyroid patients post-thyroidectomy require 1.6-1.8 mg/kg/die of Levothyroxine (L-T4). A persistent TSH level above the upper limit despite a daily dose >1.9 mg/kg/die is defined as “refractory” hypothyroidism in adults. Malabsorption and “pseudo-malabsorption” need to be investigated in case of therapeutic failure. L-T4 absorption test (LT4AT) is useful in distinguishing these two conditions but it has only been described in adult age. We ...

A 17-year-old girl comes to our attention for a second opinion due to reduced bone mineralization. She has a family history of osteogenesis imperfecta: her mother and younger sister have a COL1A1 mutation. The girl never had any fractures, but considering the familiarity it was carried out a DEXA, showing a Z-score of -1.9 SDS at the femoral level and -2 SDS at the lumbar level; no fractures visible in the spine X-ray. The genetic analysis of COL1A1 was carried out, which came...
