Sitosterolemia is an autosomal recessive disorder affecting lipid metabolism which is characterized by decreased biliary excretion and increased absorption of plant sterols and cholesterol, leading to significantlyelevated serum levels of plant sterols. Approximately 80 homozygous or compound heterozygous variants in adenosine triphosphate-binding cassette subfamily G genes (ABCG5/ABCG8) genes have been described in patients with genetically confirmed sitosterolemia. Clinicall...

Aim: Case report of an 18-month-old child with a background of vitamin D dependent rickets type 1(VDDR1)], due to a mutation of CYP27B1 (c.1319_1325dup and c.335C>T: compound heterozygote).Methods: Presentation of the case and the management of hypocalcemia as well as the complications of follow-up.Results: The patient presented at the A&Es of the 2nd Department of Pediatric...

Micropenis is defined as a penile length less than 2.5 SD below the mean value for a given age (eg, <2.5 cm at term). Nowadays, it should be also diagnosed in utero by sonography. The incidence of micropenis has been reported as 1.5/10.000 male infants in Usa, 5/1.442 in France and 18/2710 in Brazil, suggesting geographical differences or different assessment. Micropenis represents a clinical sign, that may be part of various clinical conditions, such as hypogonad...

Introduction: The association between type 1 diabetes (T1D) and celiac disease (CD) has been described by many authors in both children and adults. The link between these two pathologies was identified more than 30 years ago, especially by pediatricians. The aim of this work was to study the clinical, biological, and evolutionary features of CD in diabetic children compared to a control group of non-celiac diabetic children.Patie...

Background: Congenital Proopiomelanocortin deficiency (POMC) is a rare autosomal recessive disorder characterized by the association of adrenal insufficiency, early onset obesity, hyperphagia and altered skin & hair pigmentation. POMC is a complex propeptide encoding a range of melanocortin peptides that are released by tissue-specific proteolytic processing. These peptides have important roles in a range of functions such as skin pigmentation and the cont...

Effective management of Type 1 diabetes can be challenging. We would like to discuss the management of a 7 year old boy with Type 1 Diabetes, Lissencephaly and global severe developmental delay with medically refractory epilepsy who was introduced to and managed on a Ketogenic diet to try and improve his seizure control. He is non mobile and non-verbal and purely gastrostomy fed. He has diagnoses including. Lissencephaly and band heterotopia, absent corpus callosum, microcepha...

Background: Jansen’s Metaphyseal Chondrodysplasia is a rare autosomal dominant condition caused by activating mutations in the parathyroid hormone/parathyroid hormone related peptide receptor (PTH1R). It is associated with persistent PTH-independent hypercalcemia and hypercalciuria from an early age. Our patient, a 2 year old boy with genetically proven Jansen’s Metaphyseal Chondrodysplasia, developed bilateral medullary nephrocalcinosis secondary to persistent hyper...

Background: Severe hypertriglyceridemia (HTG) is a very rare complication of childhood diabetic ketoacidosis (DKA). The exact mecanism is unclear but transient insulin deficiency may cause a decrease in the activity of lipoprotein lipase. We report a case of girl with DKA and HTG.Case report: A 14-year-old girl, previously healthy and nonobese, presented with DKA following two months malaise, two weeks of polyuria and polydipsia. She was found to have DK...

Introduction: Graves' disease is the most common paediatric cause of hyperthyroidism. Although hyperthyroidism has been reported to cause a decrease in bone mineral density (BMD), its association with recurrent bone fractures is extremely rare.Case: A 10-year-old male patient, who had a pre-existing 7-year diagnosis of autism spectrum disorder, presented to emergency with right leg pain that started after collision with an armchair. On initial exami...

Introduction: Post-operative management of fluid and electrolyte imbalance after surgery for pituitary or suprasellar tumors could be challenging. Post-operative course could include diabetes insipidus (DI) (transient or permanent) or a classical triphasic response (initial phase of DI followed by a second phase of transient SIADH and third and final phase of permanent DI). Mainstay of management of SIADH in these patients involves fluid restriction. At times,...
