Background: Hyperinsulinemic hypoglycemia (HH) is a consequence of unregulated insulin secretion by pancreatic β-cells. Congenital HH is caused by mutations in genes involved in regulation of insulin secretion (ABCC8, KCNJ11, GLUD1, CGK, HADH, SLC16A1, HNF4A and UCP2). Severe forms of congenital HH are caused by inactivating mutations in ABCC8 and KCNJ11, which encode the two components of th...

Background: Adipose tissue acts as an endocrine organ, secreting biologically active molecules in response to external stimuli or lipid overloading. These adipose tissue-derived signaling molecules include adipokines such as leptin, adiponectin and resistin (4). On the other hand, ghrelin is the hunger hormone and an endogenous growth hormone secretagogue.Objective and hypotheses: This study aimed to investigate the relation between weight gain and serum...

Background: Hyperinsulinemic hypoglycemia (HH) is the most common cause of severe, persistent neonatal hypoglycemia. Treatment of diffuse forms that is unresponsive to diazoxide and octreotide is near total pancreatectomy.Objective: To describe the clinical characterization of a newborn with congenital HH due to a diffuse pancreas lesion and unresponsive to diaxoside.Case report: Preterm term male of 33 weeks born to non-consanguin...

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare and life-threatening primary immunodeficiency characterized by widespread autoimmunity. Mutations in the FOXP3 gene have been identified as the cause for IPEX syndrome.Objective and hypotheses: To describe clinical characteristics and genetic finding in the first Vietnamese patient with mutation of FOXP3 gene.Meth...

Background: Glucocorticoids play an important role in the developing fetus; the most important of which is lung maturation by increasing surfactant production and release. Glucocorticoid receptor (GR) functioning changes throughout the fetal period, especially during the transition to extrauterine life. Given the importance of glucocorticoids in lung development and functioning, studying glucocorticoid sensitivity (GS) in this population would be helpful, especially in the pre...

Background: Persistent Hyperinsulinemic Hypoglycemic of Infancy (PHHI) is a clinically and genetically heterogeneous disorder with familial and sporadic form due to dysregulation of insulin secretion, PHHI is a severe disease that leads to brain damage. In diffuse type near total pancreatectomy has become the mainstay of surgical therapy for patients with PHHI who did not respond to medical therapy.Objective and hypotheses: To early detected cases of PHH...

Background: It is not an uncommon situation that newborns have normal serum Ca, P, Mg, ALP, and PTH levels despite low vitamin D. Serum vitamin D binding protein (VDBG) may play a role for this situation. However, there is no any study investigated the relationship between serum vitamin D and VDBP in postnatal period.Objective and hypotheses: The aim of this study is to examine the relationship between serum vitamin D level and VDBP in neonates who have ...

Background: Intra uterine growth retardation (IUGR) is well recognized to result in infants born small for gestational age (SGA). Early morbidity is followed by increased lifetime risks for health problems, particularly in the 10% of IUGR infants who fail to catch up. Risks include metabolic syndrome with obesity, insulin resistance, abnormal glucose metabolism, hypertension, dyslipidaemia, T2DM. Rapid weight gain in infancy is associated with increased incidence of later obes...

Background: Primary hyperparathyroidism (PHPT) in children and adolescents is rare. Sporadic forms are more frequent and correspond, usually, with an adenoma (73%). Most rare familial forms (7%) are related to hyperplasia. They may be isolated or integrate with multiple endocrine neoplasia (MEN). The PHPT is revealed mostly by chronic bone pain increased by pressure, walking and exercise, arthralgia, growth failure and nonspecific late deformities.Object...

Background: The exact mechanisms on growth are not fully eluciated, but they involve insulin resistance, fetal hyperleptinemia, hypothalamic changes. The adipose tissue-derived signaling molecules include adipokines such as leptin, adiponectin and resistin. On the other hand, ghrelin is the hunger hormone and an endogenous growth hormone secretagogue.Objective and hypotheses: This study aimed to investigate the relation between growth and serum insulin, ...

Background: Monitoring of thyroid function in neonates born from mothers affected by autoinmune thyroid disease is not perfectly established. The influence of etiology of maternal disease, maternal thyroid peroxidase antibodies (TPOAb) and l-thyroxine therapy during pregnancy on neonatal thyroid function were also investigated.Method: 194 term neonates were tested for thyroid function by measurement of free thyroxine (FT4</s...

Background: Neonatal diabetes, diabetes diagnosed before six months of age, is rare, with incidence of approximately 1:90 000–160 000 live births. In approximately half of cases, neonatal diabetes istransient and usually resolves between 6 and 18 months of life. In the remainder of cases, the diabetes is permanent. Mutations in the GLI-similar 3 (Glis3) gene encoding the transcription factor GLIS3 are a rare cause of permanent neonatal diabetes and conge...

Background: Birth chest circumference (BC) may be related to Insulin-like-Growth-Factor-I blood serum levels (IG1) in the human newborn (NWB).Objective and hypotheses: We evaluated the relevance of birth body weight (BW) to birth crown-heel length (BL) ratio (BW through BL, BW/BL) in BC relations to IG1 after control for BW for birth gestational age (GA)<=10th centile (SGA), respiratory oxygen supplementation (O2S) and assisted ventilation of any kin...

Background: Pseudohypoaldosteronism (PHA) is a rare entity inducing, in case of late or missed diagnosis, life-threatening clinical and biochemical complications.Objective and hypotheses: To report a case of 4-week-old boy with failure to thrive, dehydration, hyponatremia, hyperkalemia, metabolic acidosis. The first diagnosis was congenital adrenal hyperplasia, but in the evolution, the right diagnosis of PHA was retained.Method: T...

Background: 16 year old female neonate presented with neonatal diabetes, congenital hypothyroidism and sepsis.Objective and hypotheses: To evaluate the neonate for a common cause of neonatal diabetes, congenital hypothyroidism and sepsis and to explore for the best modality of management, including a possible role for sulphonylureas.Method: The neonate born of 3rd degree consanguinity was admitted and started on insulin infusion an...

Maternal new-diagnosed Graves’ disease is quite rare thyroid dysfunction with an estimated incidence of 0.4–1% of all pregnancies, but only 1–5% of newborns delivered to mothers with Graves’ disease develop overt clinical signs and symptoms of hyperthyroidism. Neonatal hyperthyroidism almost always is transient and results from the transplacental passage of maternal thyrotropin (TSH) receptor stimulating antibodies. Neonates born to mothers with Graves&#146...

Background: It is often difficult to establish whether hyperthyrotropinemia in preterm newborn is a simple physiologic energy sparing phenomenon or a true hypothyroidism requiring replacement treatment.Objective and hypotheses: This study aimed to find in what extent thyroid function in the preterm newborn can be influenced by clinical characteristics and complications.Method: We studied 35 preterm newborn, gestational age (GA) 32....

Background: Permanent neonatal diabetes mellitus (PNDM) is a rare form of monogenic diabetes with onset less than 6 months of age. Together, activating mutations in KCNJ11 and ABCC8 genes, that encode the Kir6.2 andsulfonylurea receptor 1 (SUR1) subunits, respectively, account for nearly 50% of PNDM cases.Case report: We present a case reported a child diagnosed with PNDM resulting from a new mutation in the insulin (INS) gene, leading to severe hypergly...

Background: Hyperinsulinism/hyperammonaemia (HI/HA) syndrome is associated with postprandial hypoglycaemia and mild hyperammonemia. There is increased insulin release following protein ingestion, which is amenable to diaxozide therapy. While developmental delay and normoglycaemic seizures can also occur, hepatomegaly has not been reported. We report a child with HI/HA and hepatomegaly, mild learning difficulty and obesity, who was initially mistaken to have glycogen storage di...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare syndrome characterized by unresponsiveness or resistance to the action of aldosterone. It manifests with persistent salt loss, resulting in hyponatremia, hyperkalemia and metabolic acidosis. High levels of aldosterone and renin activity, confirms the diagnosis. When the inheritance pattern is autosomal recessive it expresses as a severe systemic disease. Often occurs in the neonatal period and presents with recurrent ...

Background: Birth chest circumference (BC) may be related to Insulin-like Growth Factor (IGF)-Binding-Protein-3 blood serum levels (IB3) in the human newborn (NWB).Objective and hypotheses: We evaluated the relevance of birth body weight (BW) to birth crown-heel length (BL) ratio (BW through BL, BW/BL) in BC relations to IB3 after control for BW for birth gestational age (GA)<=10th centile (SGA), respiratory O2 supplementation (O2S), assisted ventila...

Pseudohypoaldosteronism is one of the least explored questions in clinical endocrinology. That leads to complexity in diagnosis and differential diagnostics of disease. A boy, aged 13 days was admitted to the hospital with complains: vomiting, low weight gain, constipation. Biochemical blood assay (BBA) and acid-base balance of blood: level of sodium – 127 mmol/l (N 132–145 mmol/l), potassium – 6.6 mmol/l (N 3.1–5.1 mmol/l), chlorine &#15...
