Background: Congenital hypothyroidism (CH) is the most important cause of preventable mental retardation. Therefore, screening programme has been using for early detection of hypothyroidism in our country since 2007.Objective: To compare clinical features of newborns with and without CH who were detected in screening programme between 2009 and 2014.Method: This study enrolled 710 (344 Girls) newborn referred from CH-screening progr...

Introduction: Subcutaneous fat necrosis (SFN) of the newborn is an inflammatory disorder of the adipose tissue that rarely disease which may be complicated with potentially life-threatening hypercalcemia. The etiology of hypercalcemia was related to persistently elevated 1,25-dihydroxyvitamin D3 levels.Case: The case 47 days (length 0.3 SDS; weight −1.48 SDS) who presented sucking difficulty and debility duo to hypercalcemia with an init...

Background: Bilateral adrenal haemorrhage is rare in the neonates and more rarely does it manifest itself as acute adrenal insufficiency (AI). Cytomegalovirus (CMV)-associated AI is a well-known in adults with acquired immunodeficiency syndrome. AI is not a common finding in children with congenital CMV infection. We describe herein the case of a newborn infant presenting with adrenal hematomas (AH), AI and congenital CMV infection.Case report: A 20 day-...

Background: There is increasing interest in vitamin D nutrition during pregnancy because of widespread reports of a high prevalence of low vitamin D status in pregnant women in high-latitude areas. It has been related to adverse events in mother and child. Neonates present a greater risk of hypocalcaemia, rickets and a higher incidence of infections during the 1st year of life.Objective and hypotheses: Real situation of pregnant women and newborn in rela...

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in childhood. Over the past decades, survival rates increased, but relapse is still associated with a poor prognosis, especially if the bone marrow (BM) is affected. Marrow adipose tissue (MAT) constitutes a major part of the BM niche, but its impact on normal hematopoiesis versus leukemia initiation, progression and relapse has only recently gained attention. MAT is very sensitive to changes in the patient’s...

Background: Congenital hypothyroidism (CH) is the commonest congenital endocrine disorder and the primary cause of treatable mental retardation. In low-income countries lacking newborn screening programs, CH remains a serious public health problem.Objective: To investigate the characteristics at diagnosis and clinical outcome of patients with CH in Algeria; and determine factors related to psychomotor development.<p ...

The CYP21A2 and the TNXB genes are highly homologous with their corresponding pseudogenes (CYP21A1P and TNXA), leading to frequent homologous recombination. The TNXB includes 43 exons, the mRNA encodes tenascin-X (TNX), an extracellular matrix glycoprotein, highly expressed in connective tissue.CAH patients with a "contiguous gene syndrome" comprising a deletion of both genes- CYP21A2 and TNXB have been described. Chimeric genes generated by larg...

Hyperinsulinism is a common cause of severe and persistent hypoglycaemia during the neonatal period. Eleven genes have been identified that lead to unregulated insulin secretion and hyperinsulinemic hypoglycaemia (HH). Inactivating mutations in UCP2 gene have been described in a very small number of patients with HH. UCP2 protein is an inner mitochondrial carrier protein and its loss of function causes enhanced glucose oxidation and increased intracellular ATP synthes...

Background: Testosterone levels in newborns are changing over the first weeks of life. This dynamic change is making the assessment of infants with ambiguous genitalia complicated. The Clinical laboratory at Karolinska offer two different methods for measurement of serum testosterone, ECLIA (electrochemiluminescense immunoassay) and Liquid chromatography–tandem mass spectrometry (LC–MS/MS). It is important to evaluate these two metho...

Backgrounds: The prevalence of congenital malformations (CM) is higher in infants referred with capillary (c) TSH elevation on newborn screening. However, establishing the prevalence of CM ± dysmorphic syndromes in true congenital hypothyroidism (CH) requires careful distinction between true and transient CH.Objective: To determine the prevalence of CM ± dysmorphic syndromes in all infants referred with TSH elevation on newborn screening in Sco...
