Endocrine and metabolic disorders in adolescent and adult patients born small for gestational age.

Children born small for gestational age (SGA), defined by a birth weight and/or length standard deviation score (SDS) of < -2 based on an appropriate reference population, represent a diverse group due to multiple underlying causes of reduced growth. This classification results in a heterogeneous patient cohort. SGA children are prone to endocrinological and metabolic issues not only in childhood but also extending into adolescence and adulthood.

The The use of oral glucose-lowering agents (GLAs) in β-thalassemia patients with diabetes: Preliminary data from a retrospective study of ICET-A Network.

Objective: The management of prediabetes and hyperglycemia is an increasingly important aspect of care in patients with thalassemia. In light of the limited evidence about the management of GD (glucose dysregulation) with glucose-lowering agents (GLAs), we have conducted a retrospective survey in TDT and NTDT patients with diabetes mellitus to collect more detailed information on GLA use in order to make preliminary recommendations.

Study Design And Method: A questionnaire was prepared and distributed to the tertiary thalassemia care Centers of ICET-A Network.

The role of pelvic ultrasound for the diagnosis and management of central precocious puberty: An update.

Sexual precocity refers to the appearance of physical and hormonal signs of pubertal development at an earlier age. It may be considered as the expression of secondary sexual characteristics prior to the pubertal age In central precocious puberty (CPP), which is gonadotropin-dependent, early maturation of the entire hypothalamic-pituitary-gonadal (HPG) axis occurs, with the full spectrum of physical and hormonal changes of puberty. True precocious puberty in girls must also be distinguished from premature thelarche (PT), usually with breast development before the age of 3 years, and premature pubarche (PA), with the isolated development of pubic hair.

Biallelic variants in LIG3 cause a novel mitochondrial neurogastrointestinal encephalomyopathy.

Abnormal gut motility is a feature of several mitochondrial encephalomyopathies, and mutations in genes such as TYMP and POLG, have been linked to these rare diseases. The human genome encodes three DNA ligases, of which only one, ligase III (LIG3), has a mitochondrial splice variant and is crucial for mitochondrial health. We investigated the effect of reduced LIG3 activity and resulting mitochondrial dysfunction in seven patients from three independent families, who showed the common occurrence of gut dysmotility and neurological manifestations reminiscent of mitochondrial neurogastrointestinal encephalomyopathy.

Hashimoto encephalopathy: a case report and a short revision of current literature.

Hashimoto encephalopathy (HE) is a rare but controversial entity encompassing a variety of neuropsychological presentations in the setting of autoimmune thyroid disease. HE, mostly described in adults, with a female‑to‑male ratio of 4:1, is a relatively rare entity in the pediatric population and probably under recognized as a cause of acute encephalopathy in children and adolescents. A number of pathogenetic mechanisms have been suggested.

Screening of COVID-19 in children admitted to the hospital for acute problems: preliminary data.

Background: The new Coronavirus identified in Whuan at the end of 2019 (SARS-CoV-2) belongs to the Beta Coronavirus genus and is responsible for the new Coronavirus 2019 pandemia (COVID-19). Infected children may be asymptomatic or present fever, dry cough, fatigue or gastrointestinal symptoms. The CDC recommends that clinicians should decide to test patients based on the presence of signs and symptoms compatible with COVID-19.

Case Report: Acute hemorrhagic edema of infancy (Seidlmayer purpura) - a dramatic presentation for a benign disease.

We present a case of an 11-month-old girl who was referred to our unit for an erythematous rash that appeared on the face and extremities. Personal and family history was not relevant. Laboratory tests were normal.

A Concise Review on the Frequency, Major Risk Factors and Surveillance of Hepatocellular Carcinoma (HCC) in β-Thalassemias: Past, Present and Future Perspectives and the ICET-A Experience.

Due to the recent alarming increase in the incidence of hepatocellular carcinoma (HCC) in thalassemias, the present report reviews briefly the frequency, the major risk factors, and the surveillance of HCC in β-thalassemias. Over the past 33 years, 153 cases of HCC were reported in patients with thalassemia, mainly in Italy and Greece. Among HCV-infected patients, additional factors promoting the development of HCC included: advanced age, male sex, chronic hepatitis B (CHB) co-infection, and iron overload.

Acute abdominal pain in an adolescent girl with an ovarian yolk sac tumor.

Yolk sac tumor (YST) is a rare tumor that usually occurs in the first two decades of life. It is considered the second most common malignant germ cell tumor of the ovary, characterized by a rapid growth and a bad prognosis due to the frequent metastasis. We report the case of a 12-year-old girl who came to our observation for an acute abdominal pain.

A case of Kallmann syndrome associated to a novel missense mutation of the FGFR1 gene.

Background: Loss-of-function mutations of fibroblast growth factor receptor 1 gene (FGFR1) have been reported so far. These mutations have been described in the extracellular domain, consisting of three Ig-like domains in the single transmembrane helix and in the intracellular region, containing a tyrosine kinase domain and cause about 10% of all cases of Kallmann syndrome. FRGR1 mutations could be associated with non reproductive phenotype such as cleft palate and dental agenesis and a wide spectrum of reproductive phenotype.

Marital status and paternity in patients with Transfusion- Dependent Thalassemia (TDT) and Non Transfusion-Dependent Thalassemia (NTDT): an ICET - A survey in different countries.

Background: More than five decades ago, thalassemia major (TDT) was fatal in the first decade of life. Survival and quality of life have improved progressively thanks to the implementation of a significant advance in diagnostic and therapeutic methods, consisting mainly of a frequent transfusion program combined with intensive chelation therapy. Improvement also includes imaging methods used to measure liver and cardiac iron overload.

Thyroid Disorders in Homozygous β-Thalassemia: Current Knowledge, Emerging Issues and Open Problems.

Changes in thyroid function and thyroid function tests occur in patients with β-thalassemia major (TM). The frequency of hypothyroidism in TM patients ranges from 4% to 29 % in different reports. The wide variation has been attributed to several factors such as patients' genotype, age, ethnic heterogeneity, treatment protocols of transfusions and chelation, and varying compliance to treatment.

An ICET-A survey on occult and emerging endocrine complications in patients with β-thalassemia major: Conclusions and recommendations.

In adult thalassemia major (TM) patients, a number of occult and emerging endocrine complications, such as: central hypothyroidism (CH), thyroid cancer, latent hypocortisolism, and growth hormone deficiency (GHD) have emerged and been reported. As the early detection of these complications is essential for appropriate treatment and follow-up, the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A) promoted a survey on these complications in adult TM patients, among physicians (pediatricians, hematologists and endocrinologists) caring for TM patients in different countries. The data reported by 15 countries are presented.

T-cell defects in patients with germline mutations account for combined immunodeficiency.

ARPC1B is a key factor for the assembly and maintenance of the ARP2/3 complex that is involved in actin branching from an existing filament. Germline biallelic mutations in have been recently described in 6 patients with clinical features of combined immunodeficiency (CID), whose neutrophils and platelets but not T lymphocytes were studied. We hypothesized that ARPC1B deficiency may also lead to cytoskeleton and functional defects in T cells.

An ICET- A survey on Hypoparathyroidism in Patients with Thalassaemia Major and Intermedia: A preliminary report.

Hypoparathyroidism (HPT) is a rare disease with leading symptoms of hypocalcemia, associated with high serum phosphorus levels and absent or inappropriately low levels of parathyroid hormone (PTH). In patients with thalassemias it is mainly attributed to transfusional iron overload, and suboptimal iron chelation therapy. The main objectives of this survey were to provide data on the prevalence, demographic and clinical features of HPT in thalassemia major (TM) and intermedia (TI) patients living in different countries, and to assess its impact in clinical medical practice.

Vitamin D and Risk for Vitamin A Intoxication in an 18-Month-Old Boy.

Hand X-ray in pediatric endocrinology: Skeletal age assessment and beyond.

Skeletal age assessment (SAA) is a clinical procedure which is used in determining the SA of children and adolescents. Bone development is influenced by a number of factors, including nutrition, hormonal secretions, and genetics. There are several factors to be borne in mind when using methods of assessing skeletal maturity.

Insulin-like Growth Factor-1 (IGF-1): Demographic, Clinical and Laboratory Data in 120 Consecutive Adult Patients with Thalassaemia Major.

Introduction: IGF-1 deficiency in TM patients in children and adolescents has been attributed to chronic anemia and hypoxia, chronic liver disease, iron overload and other associated endocrinopathies, e.g. growth hormone deficiency (GHD).

Towards an optimization of the management of endocrine complications of thalassemia.

Children with thalassemia are living longer due to better care. Physicians dealing with this group of patients now have to contend with new challenges resulting from iron overload. Endocrine complications represent the most common morbidities encountered.
