Introduction: Pseudohypoaldosteronism type II (PHA II) is an extremely rare disorder characterized by low plasma renin and aldosterone when a normal renal function with hypertension, hyperkalemia, and hyperchloremic metabolic acidosis. PHA II is also known as familial hyperkalemic hypertension or Gordon’s syndrome and is an inherited autosomal dominant. PHA II could be caused by pathogenic variants of WNK1, WNK4, KLHL3, and <em...

Background and Aim: Gonadotropin-releasing hormone analogs (GnRHa’s) are the standard medical treatment for precocious puberty. Studies on their side effects in adults have shown that these drugs can cause changes in electrocardiography (ECG) along with some cardiovascular effects; however, the number of studies on children is limited. This study aims to investigate the effect of these drugs on ECG parameters in children diagnosed with central precocious puber...

Introduction: Panhypopituitarism is a deficiency of two or more pituitary hormones. Etiological causes of panhypopituitarism include pituitary developmental disorders, traumatic damage, inflammatory and neoplastic diseases affecting the pituitary, and vascular disorders. In this very rare condition, symptoms and signs related to anterior and posterior pituitary hormone deficiency can also be seen, as well as symptoms and findings related to etiological factors...

Introduction: The aldosterone synthesis is dependent on aldosterone synthase (AS), an enzyme encoded by the CYP11B2gene, one of the cytochrome P450 enzymes (P450c11Aldo). It catalysis the final steps of adosterone biosynthesis.Case: A 10 days old boy is presented with poor feeding, jaundice and weight lost. He was born from a 35 years old mother, as 4 th children, from consanguineous parents. One sister and one brother o...

Introduction: Craniopharyngioma is a low malignant potential tumor of embryological origin of the sellar/suprasellar region. It occurs with various symptoms and signs such as headache, vomiting, vision loss and endocrinological disorders. It was aimed to evaluate the presentation findings and endocrinological disorders in the follow-up in childhood craniopharyngioma cases.Methods: The patients followed up with the diagno...

Introduction: The most common congenital malformations of the scrotum are bifid scrotum, penoscrotal transposition, and ectopic scrotum. Scrotal agenesis is a very rare congenital anomaly characterized by the absence of scrotal rugae in the perineal tissue between the penis and anus. To date, 9 cases with complete scrotal agenesis have been described in the literature. Here, a case with complete scrotal agenesis with MAB21L1 homozygous mutation is presented to...

17 alpha hydroxylase, 17–20 lyase deficiency is an autosomal recessive inherited congenital adrenal hyperplasia type which is due to mutation in CYP17A1 gene and characterized with adrenal and gonadal sex steroid deficiency, delayed puberty in girls, XY sex development disorder in boys and hypergonadotrophic hypogonadism in both gender.Case: 15 year old girl referred to our clinic with vomiting, fatigue and muscle spasms. In her physical examination...

Background: P450 oxidoreductase (POR) deficiency is the newest form of congenital adrenal hyperplasia first described in 2004. POR is a protein that transfers electrons from NADPH to all 50 microsomal forms of cytochrome P450. Mutations that cause POR deficiency result in partial deficiency of the enzymes 21-hydroxylase and 17α-hydroxylase. Remarkable clinical features of the POR deficiency are genital ambiguity in both sexes, glucocorticoid deficiency and Antley-Bixler s...

Background: Stevens-Johnson syndrome (SJS) is an acute life-threatening dermatosis characterised by conjunctivitis, oral ulcerations, fever, and erythematous macules. The most important etiological factors are infections and drugs including anticonvulsants and nonsteroidal anti- inflammatories.Objective and hypotheses: Cases with both SJS and type 1 diabetes mellitus have been reported rarely in the literature. Herein, we report a diabetic case of recurr...

Introduction: The SLC34A1 gene encodes the NaPi-IIa cotransporter, which plays an important role in phosphate reabsorption in the kidney proximal tubule. Inactivating mutations of this gene cause nephrolithiasis and osteoporosis, together with clinical pictures such as hypophosphatemic rickets type 1, Fanconi renotubular syndrome type 2, and infantile hypercalcemia type 2.Case: A 40-day-old male patient presented with me...
