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: Hypoparathyroidism is typically managed with calcitriol/alfacalcidol. Close monitoring of serum calcium is required as under-treatment causes symptomatic hypocalcaemia while over-treatment will cause nephrocalcinosis. We report three cases who demonstrated resistance to treatment during an intercurrent illness, necessitating increase in medication doses and monitoring.Objective/hypotheses/method/results: Case series Case 1: Two-month...

Testicular adrenal rest tumors (TARTs) may develop in some patients with congenital adrenal hyperplasia (CAH), probably from overstimulation of adrenocorticotrophic hormone (ACTH) to remnants of intra-testicular adrenal tissue. TARTs can lead to structural testicular damage and infertility. Although rare, they may occur when CAH patients are non-compliant with glucocorticoid therapy. Due to their deep-sited location, usually only TARTs of more than 2 cm are palpable, hence, th...

Background: The primary cause of calciopenic rickets is often vitamin D deficiency (VDD) or restricted calcium intake. It can also be caused by inactivation or resistance to vitamin D due to genetic mutations. Vitamin D genetic causes can present as early as 6 months of age in previous reports. We present here a 2-month-old baby with biochemical and radiological features highly suggestive of a metabolic bone disease likely genetic rickets. However, the baby al...

Background: Autoimmune polyglandular syndrome type 3 (APS3) comprises a wide spectrum of autoimmune endocrine disorders other than adrenal insufficiency. It includes the association of autoimmune thyroid disease (ATD) with type 1 diabetes (T1D) which is known as APS3 variant (APSA3v). Genes linked to possible joint susceptibility for APS3v have been reported in few cases. We report a 10-year-old girl with Graves’ disease (GD) who developed T1D after 6 years of the diagnos...

Background: The commonest cause of 46, XX disorders of sex development (DSD) is congenital adrenal hyperplasia (CAH). We report two female virilised siblings with uncontrolled CAH who were reared as boys since birth. Different team members were involved in management. We discuss here gender reassignment and the psychosocial implications from Islamic perspectives.Case reports: An eight and 11 years old severely virilised CAH Yemeni girls were raised as bo...

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: Marfan syndrome is an autosomal dominant disorder due to a mutation of the FBN1 gene of chromosome 15 that produces fibrillin, a connective tissue protein. Tall stature can be of a major concern especially in a girl patient. Here we discuss a case of a 13-year-old girl with MFS with tall stature and multiple associated comorbidities that pose challenges in her management for the whole family.Case Report: A ...

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...
