Background/aim: Limited studies have delved into the association between thyroid hormones and neurocognition in attention-deficit/hyperactivity disorder (ADHD). We aimed to evaluate the relationship between thyroid hormone levels and neurocognitive functions in patients with ADHD.Method: A total of 146 patients with early-onset ADHD were included in the study. The inclusion criteria for patients with early-onset ADHD wer...

In accordance with the present data on children with nutritional rickets, there are three stages for biochemical findings. We aim to update the stages of nutritional rickets. Biochemical manifestations of nutritional rickets were first described in 2005 as three stages of vitamin D deficiency. Table 1 shows the biochemical findings according to the rickets stage. Accordingly, the first stage is characterized by osteopenia and subclinical hypocalcemia. The second stage begins w...

Congenital rubella infection is a transplacental infection that can cause intrauterine growth retardation, cataract, patent ductus arteriosus, hearing loss, microcephaly, thrombocytopenia and severe fetal injury. It has been shown that type 1 diabetes mellitus develops in 12–20% of patients with congenital rubella infection and disorder in oral glucose tolerance test is observed in 40%. A 13-year-old male patient presented with complaints of new-onset polydipsia, urinatio...

Background: CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature) syndrome is a recently described autoinflammatory disease that manifests in early infancy with recurrent fever, violaceous swelling of the eyelids, purpuric skin lesions, hypochromic anemia and elevated acute phase reactants. It is autosomal recessively inherited and associated with partial lipodystrophy, growth retardation and hepatomegaly. PSMB8 (proteasome subu...

Background: 17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) deficiency is a rare cause of 46,XY sex reversal due to a defect in conversion of androstenedione to testosterone. It is autosomal recessively inherited and caused by mutations in 17HSD3.Objective and hypotheses: To define clinical and laboratory characteristics of 17β-HSD3 deficiency during neonatal period.Method: An 8-day-old newborn with female externa...

Aim: Osteopetrosis is caused by autosomal mutations occurring in nine genes (TNFRSF11A, TNFSF11, TCIRG1, CLCN7, OSTM1, SNX10, PLEKHM1, CA2, and LRP5). Detecting the aetiology and providing genetic counselling via individual mutation analysis of all these genes is expensive and time consuming. Whole exome sequencing is currently increasingly used given that the cost and the time needed are similar to that of single gene sequencing analysis. Here, two newborns,...

Background: Type 1 diabetes mellitus is characterized by presence of several organ specific autoantibodies. Anti-cyclic citrullinated peptide (anti-CCP) antibody is a promising marker of rheumatoid arthritis (RA) which is known to coincide with autoimmune diabetes. Presence of these antibodies was not investigated in children with type 1 diabetes.Objective and hypotheses: To evaluate presence of anti-CCP antibodies in children with type 1 diabetes compar...

Aim: Acrodysostosis is a rare genetic syndrome characterized by small hands and feet with short, stubby fingers and toes, cone shaped epiphyses, broad nasal root, various abnormalities of mandible, skull, and vertebra, short stature, and mental retardation. Because of the hormone resistance that would accompany, acrodysostosis can be confused with pseudohypoparathyroidism. Mutations of PRKAR1A and PDE4D are reported to be responsible for the disease in less t...

Background: MODY is an autosomal dominant inherited type of diabetes with significant genetic heterogeneity. To date, there are mutations in more than ten different genes that result in the MODY phenotype and new mutations causing MODY are still being found.Objective and hypotheses: In this study, we aimed to perform a molecular analysis of pediatric MODY patients by next-generation sequencing which enables the simultaneous analysis of multiple genes in ...

Introduction: Short stature is a common manifestation of Noonan syndrome (NS). GH deficiency, GH insensitivity, and neurosecretory dysfunction have been reported in the literature. The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...
