Background: Dual-specificity tyrosine phosphorylation-regulated kinase 1B (DYRK1B) is a nutrient-sensing protein that suppresses the RAS–RAF–MEK pathway and is known to have a role in glucose uptake and glycolysis. The expression of DYRK1B increases during adipogenic differentiation suggesting an important role in adipogenesis. Mutations in DYRK1B have been described in three Iranian families and five Caucasian patients w...

Background: The leptin-melanocortin pathway is pivotal in appetite and energy homeostasis. Pathogenic variants in genes involved in this pathway lead to severe early-onset monogenic obesity (MO). The MC4R gene plays a central role in the leptin-melanocortin, and variants predominantly heterozygous in this gene, are the most common cause of MO. We identified a novel heterozygous variant c.802T>C p.Tyr268His in the MC4R gene in two unrelated patients with mor...

Introduction: Graves’ disease (GD) is a leading cause of hyperthyroidism in all age groups. Clinical presentation, methods and overall goals of therapy can be variable in different age groups. We aimed to study the prevalence of GD, the attitude of treating physicians towards management preferences as well as patient response pattern amongst children and adolescents with GD in Saudi Arabia.Methods: A cross sectiona...

Introduction: Kenny-Caffey syndrome is a rare syndrome which is a primary bone dysplasia syndrome consisting of growth retardation with proportionately short stature, cortical thickening and medullary stenosis of the long bones, hypocalcemia from congenital hypoparathyroidism, and facial dysmorphism such as a prominent forehead, microphthalmia, and micrognathia. We report 13 years old with Kenny caffe syndrome who found to have a family history of the same pre...

Background: PHA is a rare, but life threatening condition, that usually presents with impressive hyperkalemia. It can be initially missed as congenital adrenal hyperplasia (CAH). We present a series of these patients to increase the awareness of treating physicians about misdiagnosis and pitfalls in management.Case Report: We admitted 4 cases in our institution between 2017-2021. Case one, three and four were all 7 days ...

Aim: Hypophosphatemic rickets (HR) is a rare renal phosphate wasting disorder commonly related to X-linked form, caused by PHEX mutations and it treatment and follow-up is challenging due to imperfect treatment options. Here we presented nationwide data on HR with initial and follow-up data on the patients presented to the pediatric endocrinology clinics before the age of 18 years.Results: From 24 centers, 158 patients (93 male/65 female) were i...

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...

We evaluated the effect of GFD on the growth of children with the classical form of CD on long-term GFD (> 2 years).Methods: We studied growth parameters (weight gain/day, BMI and BMISDS, HtSDS) and lab data for 30 prepubertal children aged 8.5 years +/−3 years with CD, who were on GFD since the age of 3.4 years +/−2.6 years (> 2 years on GFD) for duration of 1 year. The anthropometric data of 30 randomly sele...

Introduction: Because of the associations and links between abnormal placental weight and both fetal and maternal disorders, it is important to have the national normal standard for placental weight as a normality reference.Aims: To find out the national placental weight standards for babies born between 37th and 43rd weeks of gestation in all groups of males and females babies born AGA, SGA, and LGA.<p class="abstex...

Introduction: Many potential factors can affect or be influenced by placental size. These include gestational age, maternal age, race, socioeconomic status, and gender of the baby.Aim: We investigated the possible association/s between placental weight on the one hand and birth weight, gestational age, maternal age, and gender of the baby in a large cohort of newborns (n = 80722)Me...
