Introduction: Fulminant type 1 diabetes (FT1D) occurs because of a sudden and almost total destruction of pancreatic β-cells, triggered by a viral infection. FT1DM may cause diabetic ketoacidosis (DKA) and even sudden death. Thus prompt diagnosis is vital.Case Report: Antibiotic treatment was started for a 4-year-old female patient because of a fever and cough. On the second day of treatment, she was admitted with r...

Introduction: Pituitary stalk interruption syndrome is a rare congenital abnormality of the pituitary gland manifesting with varying degree of anterior pituitary insufficiency. It is presented with isolated growth hormone deficiency or multiple anterior pituitary hormone deficiencies. It is characterized by the triad of thin or interrupted pituitary stalk, hypoplasia or aplasia of adenohypophysis and ectopic or absent neurohypophysis. It is manifested with hyp...

The genetic causes of 46, XY disorders of sex development (DSD) are mostly unknown, having been identified in only 20-35%. Mitogen-activated protein kinase 1, part of the MAPK signaling pathway, which controls testicular development, is one of the etiological genetic pathways. Here, we present a case of 46, XY DSD with heterozygous MAP3K1 variant. A 6-month-old baby was referred to pediatric endocrinology because of ambiguous genitalia. They were born by C-section at 28 weeks ...

Introduction: Homozygous leptin (LEP) and leptin receptor (LEPR) mutations lead to childhood-onset obesity due to deficient leptin signaling. The specific aims of this work are to explore genotype/phenotype correlations in a national multicenter cohort of 18 subjects with leptin (LEP) and leptin receptor (LEPR) deficiency, report on the long-term clinical follow-up of these rare cases, and systematically review all patients with pathogenic <e...

Introduction: Peripheral precocious puberty is a non-gonadotropin-dependent early pubertal development. Exogenous intake of sex steroids, gonadal or adrenal pathologies, ectopic hCG-secreting lesions play a role in the etiology. Adrenal tumors is a rare cause of heterosexual precocious puberty.Case: An eight-year-old female patient was admitted with the complaints of genital hair growth and breast enlargement. The patien...

Background: Rokineticin receptors (PROKR1 and PROKR2) belong to the family of G protein-coupled receptors. Bi-or mono allelic mutations in PROKR2 gene have been identified in Kallmann syndrome which is characterized by hypogonadotropic hypogonadism and anosmia/hyposmia. Recently, PROKR2 mutations were reported in patients with multiple pituitary hormone (MPHD) and growth hormone deficiencies (GHD), suggesting a potential role for the PROK2 p...

The aim of the study is to assess the effect of juvenile idiopathic arthritis (JIA) and biologic disease-modifying anti-rheumatic drugs (bDMARD) on ovarian reserve in children. A cross-sectional study was performed from March 2021 to March 2022 and included 81 patients with JIA and 49 healthy children. Serum anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol levels were analyzed using electrochemiluminescence methods....

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...
