Introduction: Hyperinsulinemic hypoglycemia (HH) is characterized by inappropriate insulin secretion from pancreatic β-cells despite low blood glucose levels. The most common mutations causing HH affect the KATP channel genes [ABCC8 (36.8%) and KCNJ11 (5.9%)]. This report shares the experience of transitioning from daily subcutaneous octreotide to long-acting octreotide-LAR in a patient with HH due to a KATP channel mutation.<p class...

Introduction: Lysineuric protein intolerance (LPI) is a rare autosomal recessive disorder caused by mutations in the SLC7A7 gene, which impairs the intestinal, renal and hepatic absorption of basic amino acids (lysine, arginine, ornithine). Children with LPI may present with protein avoidance, growth retardation, hepatosplenomegaly and osteoporosis. Here, we present two cases diagnosed with LPI due to short stature, with one case involving growth horm...

Introduction: The SHOX (short stature homeobox) gene, located in the pseudoautosomal region of the X and Y chromosomes, implicated in Leri-Weill dyschondrosteosis, Langer mesomelic dysplasia, idiopathic short stature. Growth hormone (GH) therapy has proven effective in promoting height gain in patients with SHOX deficiency. We will present a case who was treated for borderline precocious puberty and diagnosed with Leri-Weill dyschondrosteosis upon adm...

Background: Osteonecrosis (ON) is bone death caused by inadequate blood supply resulting in demineralization and trabecular thinning and, subsequently, mechanical failure. Although the pathophysiology of ON is not fully understood, the use of high-dose glucocorticoid (GC) is one of the triggers. Furthermore, its optimal management remains uncertain. The use of bisphosphonates (BP) for the treatment of ON has been reported, however, data on outcomes are limited...

Background: Thyroid cancers are rare in childhood. ATA guideline (Pediatric section) has been applied in daily practice since 2015. It is very significant to accurately predict the risk in the management of differentiated thyroid cancer(DTC). For this purpose, we shared our single center-20-year-experience about the follow-up features and management of childhood and adolescent thyroid cancer. We aimed to evaluate the dynamic risk stratification (DRS) and the o...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

It is known that treatment reminder digital applications improve treatment compliance & response & healthcare expenses. Groconnect (mobile reminder) application is used by patients receiving growth hormone treatment (GHt), with its injection alarm/reminder/informative videos. Here, our three month preliminary data from our one-year follow-up study (aims to determine the effects of GroConnect use on treatment compliance & treatment response) is presented.<p clas...

Background: Deficiency of one or more pituitary hormones, often with growth hormone (GH) deficiency, is defined as multiple pituitary hormone deficiencies (MPHD) or congenital hypopituitarism (CH). CH cases are mostly sporadic and have a prevalence of 1/3000-4000 live births. There are many known and yet unknown molecular pathways explaining the complex structure and functions of the pituitary gland. Many different gross and small sequence variants in the gene...

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood. Type 1 diabetes (T1DM) is the most common metabolic disease in children. The treatment of T1DM requires high executive functions and requires very intensive treatment that could be an obstacle for patients with ADHD. Dual diagnosis of T1DM and ADHD might affect treatment, control and complications of T1DM. In order to prevent long-term complica...
