Background: The pseudohypoparathyroidism (PHP) encompasses a heterogeneous group of clinical entities caused by a defect in the peripheral action of parathyroid hormone (PTH). Biochemically it manifests itself with hypocalcemia, hyperphosphatemia and elevated PTH. PHP-Ia is the most frequent and multiple hormone resistance, associated signs of Albright hereditary osteodisfrofia (OHA) and mutations in the gene encoding GNAS Gsa protein.Case presentation: ...

Background: Endocrine disruptors (ED) are chemicals that can mimic hormones and interfere with their receptors, causing endocrinological abnormalities.Clinical report: We present the case of a previously healthy, melanodermic, two-year-old female, who had a three-month evolution of clitoromegaly and generalized hypertrichosis. Endocrine blood work showed suppressed serum androgens suggesting steroid exogenous contact. Karyotype, bone age...

Background: Paediatric nephrotic syndrome has an estimated incidence of 2 per 100,000 children per year and type 1 diabetes had a reported incidence of 9.5 per 100,000 habitants in Portugal (2018 data). To the best of our knowledge, the simultaneous occurrence of nephrotic syndrome and type 1 diabetes is rare – we found 13 published cases in paediatric age worldwide. Clinical case: A 5-year-old boy with personal history of nephrotic syndrome was admitted ...

Background: Multiple Endocrine Neoplasia type 1 (MEN-1) is a rare and underdiagnosed syndrome caused by inactivating mutations of the tumor suppressor gene MEN-1 that predisposes to multiple tumors classically situated in the anterior Pituitary, Parathyroid, and Pancreas. The mutation is transmitted in an autosomal dominant way, and for this reason, the screening of all first-degree relatives is mandatory afte...

Background: In the past, the majority of the pacients with Type 1 Diabetes (DM1) had late puberty due to hipogonadotropic hipogonadism as a result of insulin deficiency. However, the use of intensive insulin therapy nowadays, results in higher BMI what can lead to an earlier puberty. Insulin administered subcutaneously is not processed by the liver, which implies increased exposure to this hormone in the ovary leading to greater activation of theca and granulo...

Introduction: X-linked hypophosphatemia (XLH), due to PHEX mutation, is the most common genetic form of rickets in children. This rare disease is characterized by decreased tubular reabsorption and increased renal loss of phosphorus due to increased FGF-23 levels. In children, XLH is often manifested by short stature, rickets and bowel limbs deformity. Conventional treatment with oral phosphorus salts and calcitriol is not always well tolerated which has a pro...

Aim: to assess and follow-up anthropometric and biochemical parameters in patients with abdominal obesity after a lifestyle intervention.Patients, Material and Methods: 122 children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a control randomized intervention study (NCT031472). Abdominal obesity was diagnosed using the waist circumference. The intervention included an intensive phase duri...

Precocious Puberty is defined by the onset of pubertal development at an age 2-2,5 standard deviations earlier than the normal population. Central Precocious Puberty (CPP) is diagnosed when the hypothalamic-pituitary axis is activated. Gonadotropin-releasing hormone analogues (Gn-RH analogues) are the main treatment option, but sometimes controversial. Whether this treatment influences children's body mass index (BMI) and a different BMI progression is still unclear.<p...

Introduction: Nelson’s syndrome is a potentially severe complication of bilateral adrenalectomy, a radical procedure performed in the treatment of hypercortisolism in Cushing’s disease (CD). We report a case of CD in pediatric age submitted to bilateral adrenalectomy with subsequent Nelson’s syndrome.Case report: Male, 5-year-old, referred to a Pediatric outpatient clinic because of growth failure, rapid weight gain and high blood pressure...

Introduction: Type 1 diabetes mellitus (1DM) has well known long term vascular and neuropathic complications. It has also been described a positive effect of good glycemic control on physical growth and pubertal development, achieved with improvement of insulin-therapy.Aim: To evaluate the effect of functional insulin-therapy on final height in children with type 1 diabetes mellitus.Methods: Retrospective analysis of a cohort of po...
