Background: It’s well known that GnRH analogue (GnRHa) could not improve the final height of mid/late pubertal girls with central precocious puberty (CPP) or early and fast puberty (EFP) for their low growth potential.Objectives: To evaluate the effect of combined treatment with GnRHa and GH on the linear growth in mid/late pubertal girls with CPP/EFP at great bone ages. To investigate the relation between C-type natriuretic peptide (CNP) and GH&#14...

Introduction: Fanconi anemia (FA) is a genomic instability syndrome associated with congenital abnormalities. Structural anomalies of the central nervous system (CNS), particularly a small pituitary gland, have been published in a few case series. This has been thought to be the cause of the short stature (SS) observed in FA.Methods: A cross-sectional exploratory study was carried out in pediatric patients at the FA Span...

Background: Initiation and progression of puberty requires concerted action of activating and inhibiting factors. Recently, cases of central precocious puberty have been linked to loss-of-function mutations of makorin RING-finger protein 3 (MKRN3) indicating a pivotal inhibitory role of MKRN3 on GnRH secretion.Objective and hypotheses: To investigate peripubertal circulating MKRN3 levels in healthy boys.Method: Healthy boys (n<...

Objectives: To evaluate the effect of combined treatment with GnRH analogue (GnRHa) and recombinant human GH (rhGH) on the linear growth in mid/late pubertal girls at great bone ages with central precocious puberty (CPP) or early and fast puberty (EFP). To investigate the relation between C-type natriuretic peptide (CNP) signaling pathway and GH’s effect on linear growth in these girls. Methods 22 girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 ye...

A broad spectrum of human diseases, including abnormalities in steroidogenesis, are caused by mutations in the NADPH cytochrome P450 oxidoreductase (POR) (1-4). Human POR is a diflavin reductase that transfers electrons from NADPH to small molecules, non-P450 redox partners and cytochrome P450 proteins in the endoplasmic reticulum. Cytochrome P450 proteins perform a very wide range of reactions, including metabolism of steroids, drugs and other xenobiotics. Therefore, genetic ...

Pubertal delay in females is defined as the lack of development of Tanner breast stage 2 by 13 years of age. Recent cohort studies have recapitulated the findings of classic studies over the last few decades, that constitutional delay (also known as self-limited delayed puberty) is less common in girls than in boys. This diagnosis is found in 30% of girls presenting with delayed puberty, with a further 30% classified as functional hypogonadotropic hypogonadism due to chronic i...

Introduction: Bilateral adrenal hemorrhage is a rare pathology, contrary to what happens with unilateral ones. It is more common in newborns and associated with situations of perinatal hypoxia, sepsis, traumatic births, or coagulation abnormalities. The classic triad includes jaundice, anemia, and a flank mass, which can lead to severe shock. Extensive bilateral hemorrhage is required to produce a situation of adrenal insufficiency. The diagnosis is made by im...

Introduction: Magnesium is the second most abundant intracellular cation, and its low level causes several side effects related to hypoparathyroidism, hypocalcaemia, and vitamin D deficiency. Furthermore, some of the cases of hypomagnesemia are linked to platinum-based chemotherapy, resulting in neurotoxicity and nephrotoxicity. Dorsal root ganglion is the main target of platinum drugs, whereby its signs and symptoms can be detected months after chemotherapy. ...

Pseudohypoparathyroidism (PHP) is a disorder caused by PTH resistance due to a genetic defect in imprinted GNAS cluster. It is characterized by high phosphorus, low to normal calcium and elevated PTH. It is classified into types 1a, 1b, 1c, pseudopseudohypoparathyroidism and type 2. Type 1a is often associated with Albright Hereditary Osteodystrophy (AHO) which is characterized by short stature, round facies, obesity, brachydactyly, ectopic calcifications and developmental del...

Introduction: Patients with Turner syndrome (TS) diagnosed beyond the age of 12 years present a real challenge for therapeutic management. Indeed, compromises must be made between the progressive induction of puberty and an efficient treatment with growth hormone to have the best possible results.Patients and methods: Our study concerns 18 cases of patients followed for ST in endocrinology consultation (CHU Constantine-A...
