Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, the interferon induced helicase domain 1 (IFIH1) gene, the TSH receptor (TSH-R) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association...

Introduction: Variants in the N-terminal of the Indian-hedgehog gene (IHH) have been associated with Brachydactyly type-A1 (AD) and Acrocapitofemoral dysplasia (AR), only three of which have been functionally studied. However, heterozygous IHH variants, majority classified as variants of unknown significance (VUS) are being increasingly identified, not only in the N-terminal but also in the uncharacterized C-terminal, by NGS, in individuals with short...

We report on a 17-year-old female patient with cramps in hands and legs since 6 months. She showed hypokalemia with high need of potassium substitution (128mmol K= 1.3 mmol/kg/d), arterial hypertension (mean 154.5/92 mmHg), polydipsia and polyuria without nocturia or salt craving. Her PMH revealed neuroblastoma stage III with high-dose chemotherapy, stem cell transplantation and obesity (36.8 kg/m2). Further investigation showed aldosterone 77.5 ng/dl (norm values: 2-10ng/dl),...

Background: Hyperthyroidism is a condition rarely found in children. In the majority of cases, it is a Grave's disease whose clinical expression is very similar to that observed in adults.Objective: describe the clinical, evolutionary and therapeutic epidemiological features in children with hyperthyroidism and especially Grave's disease.Materials and Methods: This is a ret...

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Cushing’s disease (CD) is defined as hypercortisolism secondary to an adrenocorticotropin (ACTH) secreting pituitary adenoma. It is rare in the pediatric age and early diagnosis and treatment are important to prevent long-term complications. In the diagnostic workup, bilateral inferior petrosal sinus sampling (BIPSS) of ACTH after corticotropin-releasing hormone (CRH) stimulation is the gold standard in the differential diagnosis of ACTH-dependent hypercortisolism. We re...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare pediatric disorder. The classic form occurs in 1:15,000 births worldwide. Osteogenesis imperfecta is a rare bone disease occurring in 1 in 15,000 to 20,000 births. Cow’s milk allergy (CMA) is of the commonest food allergies in early life. Our case presents the co existence of the abovementioned entities in a patient.Case report:</str...

Background: The hallmark of congenital hyperinsulinism (CHI) is the demonstration of detectable plasma insulin during hypoglycaemia. Insulin can be undetectable in a significant proportion of patients with CHI. Plasma samples for insulin requires rapid and careful handling for reliable results. There is little published data on the value of C-peptide in the diagnosis of CHI.Objective and hypotheses: To assess the usefulness of C-peptide in the diagnosis ...

Background and Aims: Children with Down's syndrome (DS) are at increased risk of autoimmune conditions including type 1 diabetes (T1D), coeliac and thyroid disease. We previously examined the clinical and immunogenetic characteristics of these conditions in children with DS. An earlier age-of-onset of diabetes was observed compared with children with T1D from the general population despite having decreased frequencies of the established genetic susceptibil...

Background: Mauriac's syndrome (MS) may occur in patients with poor controlled type 1 diabetes mellitus (DM1), with often ketoacidosis, episodes of hyperglycemia and hypoglycemia, under the dose insulin. MS characterized growth retardation and puberty delay, Cushingoid obesity, moon facies, protuberant abdomen, hepatomegaly with transaminase elevation, dyslipidemia. Now it is a rare syndrome, firstly described by Mauriac in 1930.<str...
