Background: McCune-albright syndrome is clasiically defined by the clinical triad of fibroud dysplasia of bone (FD), café-au-lait spots and precocious puberty. It is a rare disease with variable presentation caused by somatic (non-germline) gain of function mutation in GNAS gene. It can affects both endocrine and non-endocrine tissue. In addition to precocious puberty, other hyperfunctioning endocrinopathies may be involved including hyperthyroidism, growth excess, cushin...

Background: Neonatal thyroid screening is considered one of the best cost-effective tool to prevent mental retardation in population. Different strategies are suggested for thyroid hormone estimation in the sample obtained at birth using cord blood or later in neonatal period. In King Abdulaziz Medical City, cord TSH is the screening tool to detect congenital hypothyroidism cases with a cut off value of 30 MIU/l considered positive result. In 2011, newborn screening programme ...

Background: X-linked hypophosphatemia (XLH) is a rare, often debilitating genetic disorder caused by mutations in the phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX) that is characterized by excess fibroblast growth factor 23 (FGF23), hypophosphatemia, skeletal deformities, and growth impairment.1,2 Conventional therapy with the combination of phosphate and active vitamin D is associated with poor treatment adh...

Background: Sitosterolemia, a rare autosomal recessive defect in lipid metabolism, is caused by mutations in the transporter genes ABCG5 and ABCG8 coding receptors on the luminal surface of enterocytes. Thus, hyperabsorption of non-digestible plant sterol in tissue and blood resulting in cardiovascular (CVD) sequalae. Here we report a case of Sitosterolaemia incidentally diagnosed on whole exome sequencing (WES) for bony lesions in a young Saudi girl with asym...

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 ...

Introduction: Childhood cancer survivors (CCSs) has increased risk of endocrine complications, of which, abnormal growth and hypothyroidism are the commonest. The risk of developing endocrinopathy will vary according to different host factors including type of tumour and factors related to treatment modalities including chemotherapy, radiotherapy, surgery and bone marrow transplantation. we aim to assess the prevalence and associated risk factors of early deve...

Background: Complication rates following hypospadias surgery are variable and given that hypospadias may be associated with a genetic or an endocrine condition, hypospadias outcome may depend on several clinical factors that require exploration.Aim: To perform a systematic review of cases of hypospadias operated at one tertiary centre to identify clinical determinants of optimal outcome.Methods: Retrospective review of clinical rec...

Background and Aims: A congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders in which enzymes in the cortisol biosynthesis pathways are interrupted by gene mutations. More than 90% of CAH, is caused by 21-hydroxylase (21OHD) deficiency. The 17α-hydroxylase (17OHD) deficiency one of the less common forms of CAH, can result in significant morbidity and mortality if left untreated, thus making early diagnosis essential. In Saudi A...

X-linked hypophosphataemia (XLH) is the most common form of inherited hypophosphataemic rickets, caused by loss-of-function mutations in the gene encoding phosphate-regulating endopeptidase homologue X-linked (PHEX), resulting in excess circulating fibroblast growth factor 23 (FGF-23).1,2 In children, clinical features include delayed walking, waddling gait, leg bowing, pain, spontaneous dental abscesses and growth failure. Current therapies do not treat the underly...

Background: Bisphenol A (BPA), a plastic byproduct, is a known endocrine disruptor and is types of cancers, such as prostate and ovaries, and some other health conditions, for instance diabetes and obesity. It has direct effect on reproductive system through its strong oestrogen agonist activity.Objective and hypotheses: BPA has a strong oestrogen agonist activity. And oestrogen antagonize cellular activity of growth hormone (GH), however, the effect of ...
