Objectives: To evaluate the effect of combined treatment with GnRH analogue (GnRHa) and recombinant human GH (rhGH) on the linear growth in mid/late pubertal girls at great bone ages with central precocious puberty (CPP) or early and fast puberty (EFP). To investigate the relation between C-type natriuretic peptide (CNP) signaling pathway and GH’s effect on linear growth in these girls. Methods 22 girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 ye...

Introduction: Vitamin D resistant rickets type II (VDDR-II) is a disease with a difficult treatment developed as a result of mutations in VDR gene. Despite high dose active vitamin D and oral calcium treatments, sufficient recovery cannot be achieved mostly. Successful results with intravenous calcium infusion that is an alternative treatment have been reported; however, serious restrictions and complications such as hospitalization, catheter infection, thrombosis, skin necros...

Background: Hypoglycaemia is one of the most common presenting complaints at paediatric emergency department. There are many distinct causes of hypoglycaemia, ranging from nutritional insufficiency, infectious origins, to metabolic disorders. A thorough investigation can help differentiate the cause of hypoglycaemia, with subsequent tailored management. All patients with hypoglycaemia should have a full clinical assessment and together with a hypoglycaemia scr...

Background: Glucocorticoids are one of the most widely used drugs in clinical practice. Inappropriate use can result in secondary adrenal insufficiency. Adrenal insufficiency can be an occult cause of hypercalcaemia.Case presentation: A 3-months-old boy admitted for puffiness of the face, increase in weight. It was revealed that the patient was admitted to a hospital 2 months ago and was diagnosed to have congenital cataract and operated. The patient was...

Background: CYP27B1 converts 25-hydroxyvitamin D3 to active 1,25-dihydroxyvitamin D3, playing a vital role in calcium homeostasis and bone growth. Vitamin D-dependent rickets type 1 (VDDR-1) is a rare autosomal recessive disorder caused by mutations in CYP27B1.Objective and hypotheses: Enzymatic and structural analysis of mutations in a patient with calcipenic rickets.Method: Two siblings presented with calcip...

Background: N-methyl-D-aspartate receptors (NMDARs) are ionotropic glutamate receptors that are widely expressed in the CNS where they play an important role in neurotransmission and cell viability and serve as drug targets for the treatment of neurodegenerative disorders.Objective and hypotheses: Much less is known about the role of pancreatic NMDARs. Since neurons and pancreatic islets have many features in common, we hypothesiz...

Background: Turner Syndrome (TS) is associated with short stature and skeletal disproportion. The impact of treatment with recombinant human growth hormone (rhGH) and oestrogen therapy on body proportions is unclear.Objectives: To evaluate sitting height (SH) and leg length (LL) in TS before growth promoting therapies and at adult height.Method: Retrospective study of height (Ht), SH and LL standard deviation score (SDS) in TS. Bod...

Context: Nutritional vitamin D deficiency is rare in the high income countries; its manifestations are usually associated with the combination of accompanying risk factors, as malnutrition, chronic illness, dark skin or restricted exposure to sunlight due to cultural practices.Objective: The aim of this case report is to increase the awareness to severe vitamin D deficiency as a result of extreme indoor isolation due to ...

Introduction: Few studies have been published comparing the liquid and tablet formulations of L-T4 in pediatric patients, with a short follow-up period. Both formulations seemed to produce a rapid normalization of thyroid fuction with a tendency of a greater TSH inhibition in children taking the L-T4 liquid drops. The aim of our study is to compare the long-term effectiveness and saftey of both liquid and tablet L-T4 therapy in CH patients up to 3 years old via a multicenter s...

Background: Decreased serum 25-hydroxyvitamin D (25-OHD) level has frequently been reported in obesity, a condition which is associated with insulin resistance. Insulin resistance was negatively associated with serum 25-OHD. Puberty is the period with altered insulin sensitivity. Previous studies showed conflicting results of the variation of serum 25-OHD levels across pubertal stages. However, data on serum 25-OHD levels across pubertal stages in obese childr...
