Introduction: Genetic factors play an important role in determining individual susceptibility to weight gain and obesity. In the last few years, several genetic variants have been identified as monogenic forms of obesity. Among them, Leptin (LEP) and its receptor on hypothalamic neurons (LEPR) are key players in the regulation of body weight, food intake and energy homeostasis. Pathogenic variants in the LEPR gene cause severe childhood-onset obesity with an a...

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,...

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...

A 8 years and 7 months old male presented with short stature related to his target height. No history of bones fractures. The patient was 120.7 cm (- 1.77 SDS). Physical exam demonstrated peculiar facies, relative macrocephaly, delayed tooth eruption and pectus carinatum. He referred during the clinical evaluation diffuse bone pain and weakness, mostly exacerbated by sport activity. A first diagnostic investigation had already been made showing low serum alkaline phosphatase a...

The epidemic spread of obesity in children has triggered the commitment of scientific research, which has allowed us to understand its genetic basis; the different forms of genetic obesity share common clinical aspects, making it difficult to achieve a molecular diagnosis based only on our clinical suspicion. We report a female patient presented with neonatal hypotonia, hyperphagia and early onset excessive weight gain, strabismus and high hypermetropia. Regarding her neurodev...

Obesity, with its complications, emerges as a major contributor to the global health burden becoming pandemic. It's an extremely complex disorder resulting of interaction of biological, social and behavioural factors that cause increase in food intake and reduction in energy expenditure. Although few monogenic forms and indeed several susceptibility loci have been described, the molecular basis underlying early onset obesity remain largely unknown. GWAS revealed consistent...

We report a pediatric patient with an undiagnosed and complex medical manifestation who was shown to have paternal isodisomy at chromosome 7. Our case is a female patient presented for increasing overweight, parotid hemangioma and gastroesophageal reflux with laryngomalacia. She was born at 35+4 weeks of gestation and her birth weight, length and occipitofrontal circumference (OFC) were 2500 g, 49 cm and 33 cm, respectively. At the time of our visit she was 16 months old, ...

Introduction: Salt wasting is a potentially life-threatening condition in the newborn period. Other than 21 OH-CAH other rarer adrenal causes should be considered in the differential diagnosisObjective: To report the laboratory, clinical features, management and genotype of a series of consecutive patients who showed up at our Center for a salt wasting syndrome in the last 32 years, excluding patients with 21 OH CAH....

Proposal of a diagnostic flow-chart for the diagnosis of central precocious puberty (CPP) in females

Baronio Federico , Ortolano Rita , Candela Egidio , Bernardini Luca , Cassio Alessandra

Introduction: in females with precocious thelarche (PT) (< 8 years), elevation of morning luteinizing hormone levels (mLH) may be indicative of pubertal activation of the pituitary gonadal axis. However, this approach could not be satisfactory in real life management of PT due to the risk of reduced specificity and sensitivity of the mLH thresholds. We propose a diagnostic flow-chart based on basal and stimulated gonadotrophins integrated with bone age and ...
