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: Attention-deficit hyperactivity disorder (ADHD) is one of the most common psychiatric problems of adolescent and childhood. Methylphenidate is a psychostimulant drug in use of attention-deficit hyperactivity treatment as a first choice modality.Objective and hypotheses: The aim of this study is to evaluate the levels of leptin, ghrelin and nesfatin-1 in relation to slowdown in growth and poor appetite.Method: Total of 8...

Background: Premature pubarche (PP) is known to be a risk factor the development of metabolic syndrome (MS) and hyperandrogenism.Aims: To evaluate if glucose and insulin metabolism, cardiovascular risk factors and cardiovascular risk factors in family (FCVRF) create a risk for insulin resistance (IR) and if PP is a risk factor alone for MS and hyperandrogenism in normal weighted prepubertal PP girls.Methods: Prepubertal and non-obe...

Background: Premature adrenarche (PA) is defined as the appearance of pubic and/or axillary hair in girls younger than 8 years old and caused by the rise in adrenal androgen production including dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione (A4). DHEAS≥40 µg/dL is accepted as the biochemical marker of adrenarche. However, adrenals also produce 11-oxygenated C19 androgens such as 11β-hydroxyandrostene...

Background: DEAH-box protein DHX37, encodes an RNA helicase, is involved in ribosome biogenesis. Monoallelic mutations in DHX37 gene have recently been identified in 46,XY differences/disorders of sex development (DSD) patients with nonsyndromic gonadal dysgenesis as well as testicular regression, while biallelic mutations have been associated with microcephaly and structural brain abnormalities. Here, we present a patient with penoscrotal hypospadias and bil...

BMP4, a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily, is involved in the embryonic development of various organ and tissues including the cranio-facial structures, olfactory placode, pituitary, eyes, heart, and kidneys. Mutations in this gene are associated with orofacial cleft and microphthalmia in human patients. BMP4 plays an important role in the embryonic development of the GnRH neurons ...

Background: The variable presence of adrenal insufficiency (AI) due to hypocortisolemia (HC) in patients with thalassemia is well established; however, the prevalence of adrenocortical hypofunction (ACH) in the zona glomerulosa and zona reticularis of the adrenal cortex is unknown.Objective and hypotheses: To establish the prevalence of ACH, we examined the cortisol response to 1 μg- and 250 μg- ACTH tests, plasma aldosterone (A)/plasma renin a...

Background: Low-dose adrenocorticotropic hormone stimulation test (LDST) is widely used to assess patients for adrenal insufficiency. However, the predictive power of basal cortisol for the performance of LDST is not clear.Objective: To determine the appropriate basal serum cortisol cutt-off values that predict a positive or negative LDST.Design: A single-centre retrospective study...

Purpose: MODY is a monogenic diabetes with autosomal dominant inheritance that usually occurs in adolescence or young adulthood. It constitutes 1% of diabetes cases in childhood. The diagnosis of MODY is very difficult due to genetic heterogeneity, rarity, and clinical overlap with other diabetes types. In recent years, the diagnosis of MODY has become easier with genetic developments. On the other hand, misinterpretation of results can cause confusion. In thi...

Background: Deficiency of 11β-hydroxylase is the second most frequent type of congenital adrenal hyperplasia and more common in Turkey than other populations.Objective and hypotheses: The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish population.Method: 17 patients from 13 families are included in this study. Diagnosis was based on virilisation and high levels of 11-deoxycortisol. 15 case...
