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: Early tooth loss could be the consequence of the local or systemic diseases. We present an odontohypophosphatasia case with otosomal dominant mutation in ALPL gene.Objective and hypotheses: We report a case with odontohypophosphatasia and his family investigation.Method: Three-years-old boy admitted to our pediatric endocrinology clinic with toothloss without any other dental or gingival disease. His serum levels calciu...

Background: Fanconi-Bickel syndrome (FBS) is a glycogen storage disease caused by the homozygous mutations of SLC2A2 gene which codes GLUT2 protein. It is characterized by growth retardation, hepatomegaly and hypophosphataemic rickets. While most of the cases with FBS have fasting hypoglycaemia and postprandial hyperglycaemia, only few cases had been shown to have neonatal diabetes (ND).Case presentation: A 14 days old girl was admitted to hospital with ...

Background: Androgen insensitivity syndrome (AIS) is the most common cause of 46,XY sexual differentiation disorders. Clinical presentation is variable among cases with a range from a complete female to male external genitalia. There is a weak correlation between genotype and phenotype.Aım: Our aim is to report clinical and molecular characteristics of siblings with AIS.Patients and methods: Two siblings newborns with ambiguou...

Background: Idiopathic hypogonadotropic hypogonadism may be normosmic (nIHH) or it may be associated with anosmia, which is known as Kallmann syndrome (KS). First mutation GNRH1 was described in 2009 in patients with nIHH. Mutations of the human GNRH1 gene are a very rare cause of nIHH, with only six mutations so far described.Case: The proband is a 11.3-year-old boy who first presented at age 1 with micropenis and cryptorchidism. His p...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is characterised by failure of initiation or maintenance of puberty due to insufficient gonadotropin release, which is not associated with anosmia/hyposmia.Objective and hypotheses: The objective of this study was to determine the distribution of causative mutations in an hereditary form of IHH.Method: In this prospective collaborative study, families with more than one aff...

Background: Hyperthyroidism is a condition rarely found in children. In the majority of cases, it is a Grave's disease whose clinical expression is very similar to that observed in adults.Objective: describe the clinical, evolutionary and therapeutic epidemiological features in children with hyperthyroidism and especially Grave's disease.Materials and Methods: This is a ret...

Cushing’s disease (CD) is defined as hypercortisolism secondary to an adrenocorticotropin (ACTH) secreting pituitary adenoma. It is rare in the pediatric age and early diagnosis and treatment are important to prevent long-term complications. In the diagnostic workup, bilateral inferior petrosal sinus sampling (BIPSS) of ACTH after corticotropin-releasing hormone (CRH) stimulation is the gold standard in the differential diagnosis of ACTH-dependent hypercortisolism. We re...

Polycystic ovary syndrome is the most common endocrinological disease in women of reproductive age. Although it is thought that pathologies such as insulin resistance, chronic low-level inflammation and hyperandrogenism are central theme of the disease, the exact pathophysiology of the disease has not been fully understood. This study’s aim is to reveal the relationship between routine endocrinological and immunological markers related to chronic inflammation, and to inv...
