Transient TSH Elevation in Infants Referred on Newborn Screening – Features, Prevalence and Trends

Ouarezki Yasmine , Jones Jeremy , Fitch Moira , Shaikh Guftar , Donaldson Malcolm

Background: Up to 20% of infants referred on newborn congenital hypothyroidism (CH) screening are subsequently shown to have transient TSH elevation rather than permanent CH. Correct identification of such cases is important to avoid prolonged treatment with thyroxine and unnecessary clinic attendance.Objective: To determine the prevalence, trends and profile of infants with transient TSH elevation referred between August 1979 and December 2015 by the Sc...

Age at Diagnosis and Mental Development in Children with Congenital Hypothyroidism in the Absence of Newborn Screening Programme

Ouarezki Yasmine , Ladjouze Asmahane , Kherra Sakina , Djermane Adel , Laraba Abdennour

Background: The outcome of congenital hypothyroidism (CH) has dramatically changed since the start of neonatal screening. However the benefit of this program is not felt in Algeria and other countries where the pathology is still causing irreparable brain damage.Objective and hypotheses: To evaluate age at diagnosis of CH and its impact on the mental development in the absence of new-born screening.Method: Case notes of all patient...

The Influence of Pituitary MRI Findings on Clinical Presentation and Growth in GH-Treated Children with Congenital Hypopituitarism

Adel Djermane , Asmahane Ladjouze , Yasmine Ouarezki , Kahina Mohamedi , Hassina Benlarbi , Samira Aggoune , Zahir Bouzrar , Hachemi Maouche

Introduction: MRI imaging is the technique of choice in the diagnosis of children with hypopituitarism. Marked differences in MRI pituitary gland morphology suggest different etiologies of GHD, different clinical and endocrine outcome and different prognoses.Objective: To investigate the auxological, clinical and hypothalamic pituitary-MRI features in children with non-acquired growth hormone deficiency (GHD); and determ...

Diazoxide Unresponsive Congenital Hyperinsulinism due to a Novel ABCC8 Missense Mutation

Ouarezki Yasmine , Ladjouze Asmahane , Djermane Adel , Houghton Jayne , Maouche Hachemi , Bouzerar Zohir , Tayebi Youcef

Background: Congenital hyperinsulinism is a frequent cause of persistent hypoglycaemia in neonates. Mutations of the KATP channel subunit are the most common molecular defects. We report here a novel ABCC8 gene mutation causing a severe form of CHI in a newborn.Case report: A 10-day-old boy born to consanguineous parents was referred for persistent hypoglycaemia. He was born by normal vaginal delivery at 38 weeks gestation, birth weight was 4....

The Prevalence of Congenital Malformations in Infants with TSH Elevation on Newborn Screening: the Importance of Distinguishing Between True and Transient Congenital Hypothyroidism

Ouarezki Yasmine , Mansour Chourouk , Jones Jeremy , alghanay Abubaker , Smith Sarah , Stone David , Donaldson Malcolm

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...

Trends in Median Age at Guthrie Sampling, Laboratory Receipt, Notification, and Start of Treatment for Infants with TSH Elevation on Newborn Screening

Mansour Chourouk , Ouarezki Yasmine , Jones Jeremy , Smith Sarah , Donaldson Malcolm , Mason Avril

Background: Screening for congenital hypothyroidism (CH) has virtually eradicated the severe mental handicap associated with late or absent treatment. We have previously reported two audits of newborn screening for CH between 1979 and 2003 showing significant improvement from the first to more recent period.Objective and hypotheses: We aimed to audit the period 2004–2013 and report trends in timing of sampling, laboratory processing, delay between f...

Sensitivity of Measured Parental Height and Target Range in the Diagnosis of Turner Syndrome

Ouarezki Yasmine , Cizmecioglu Filiz , Mansour Chourouk , Jones Jeremy , Gault Emma Jane , Mason Avril , Donaldson Malcolm

Background: Girls with Turner syndrome (TS) are inappropriately short for their parentsÂ’ heights; measured parental height is therefore useful in diagnosis.Objective and hypotheses: To examine the sensitivity of measured parental height in the diagnosis of TS; and to audit the frequency of parental height measurement in our clinic.Method: Case note review of all girls with TS attending our dedicated Turner clinic between 1989&...

Objective vs Subjective Measurement of Thyroid Volume by Ultrasound in Infants Referred with TSH Elevation on Newborn Screening

Mansour Chourouk , Ouarezki Yasmine , Jones Jeremy , Attaie Morag , Stenhouse Emily , Pohlenz Joachim , Donaldson Malcolm

Background: Establishing thyroid size as large, normal or small in newborn infants with TSH elevation and in situ thyroid is important for diagnosis and informing molecular genetic studies.Objective and hypotheses: To compare intra-observer variation in the objective (Ox) measurement of thyroid volume (vol) by ultrasound (US); and the correlation between subjective (Sx) and Ox assessment.Method: Joint blinded retrospective...

Outcome of Congenital Hypothyroidism in Algeria: The Urgent Need to Implement a National Newborn Screening Program

Adel Djermane , Asmahane Ladjouze , Yasmine Ouarezki , Ourida Taleb Nessma , Kafia Zichi , Samira Aggoune , Bouzerar Zahir , Hachemi Maouche

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 ...

A New Mutation of MAMLD1 (CXorf6) Associated with NR5A1 (SF1) Variant in a Patient with 46,XY DSD

Background: The investigation of patients with 46,XY DSD is often difficult, with no definitive diagnosis in more than 50% of cases investigated. We describe a new mutation of MAMLD1 in a patient with 46,XY DSD who also showed an alteration in the NR5A1 gene.Case report: A 5-year-old boy was referred to our clinic for DSD. He was born to non-consanguineous parents and was diagnosed with ambiguous genitalia at birth but had not been previously investigate...
