Wolf-Hirschhorn syndrome: severe short stature and growth hormone deficiency

Ould Mohand Ouamer , Mekki Azzedine

Introduction: Wolf-Hirschhorn syndrome (WHS) is a rare congenital disorder occurring in approximately 1/50.000 births, with a 2:1 femaleto-male predominance. It results from the hemizygous deletion encompassing the 4p16.3 region. The typical craniofacial phenotype is described as a « Greek warrior helmet appearance ».Case Report: A 5-year-old boy is brought to the pediatric endocrinology consultation for shor...

Morbid obesity revealing a rare genetic disease

Ould Mohand Ouamer , Mekki Azzedine

Introduction: Prader-Willi syndrome (PWS) is a rare genetic disease characterized by hypothalamic-pituitary dysfunction associated with major hypotonia during the neonatal period. In childhood, the main problems are the appearance of hyperphagia with the risk of morbid obesity, learning difficulties and behavioral disorders. It concerns one case in 25.000 births.Observation: A 15-year-old boy from a non-consanguineous ma...

Silver-Russell Syndrome: knowing how to think about it

Ould Mohand Ouamer , Drali Ouardia , Mekki Azzedine

Introduction: Silver-Russell Syndrome (SRS) is a rare genetic disease with an estimated prevalence of 1/100,000. It is characterized by the association of severe intrauterine growth retardation, postnatal failure to thrive, particular facial dysmorphism and asymmetry of the limbs. SRS is a pathology of parental imprinting. It is dependent on several imprinted genes, acting through different molecular mechanisms.Case Report:</stro...

McCune-Albright Syndrome : knowing how to think about it

Ould Mohand Ouamer , SAdaoui Brahim , Khelfat Farah , Mekki Azzedine

Introduction: McCune-Albright syndrome (MAS) is characterized by fibrous dysplasia (FD), cafe-au-lait skin spots and precocious puberty (PP). SAM is a rare disease and its prevalence is estimated between 1/100,000 and 1/1,000,000. Somatic activating mutations of the GNAS gene located on chromosome 20q13 encoding the α subunit of the regulatory protein Gsα are responsible for the entity.Case report: This is a ...

Congenital Hypopituitarism : a pathology not to be ignored

Ould Mohand Ouamer , Sadaoui Brahim , Khelfat Farah , Mekki Azzedine

Introduction: Pituitary deficiency, or hypopituitarism, is defined by insufficient synthesis of one or more anterior pituitary hormones (growth hormone, TSH, ACTH, LHFSH, prolactin) associated or not with diabetes insipidus (ADH deficiency). In children it is more frequently congenital, due to abnormal pituitary development; it is then a rare disease with an estimated prevalence of between 1/16.000 and 1/150.000.Case report:</str...

Turner Syndrome with Neonatal Revelation: Knowing How to Think About It

Ould Mohand Ouamer , Fernane Leila , Sebar Khadidja , Lebane Djamil

Introduction: urner's syndrome (TS) is a rare genetic disorder related to the total or partial absence of an X chromosome, affecting 1/2 500 newborns of female sex. It associates almost steadily a delay in stature and ovarian failure with infertility.The other anomalies are inconstant: morphological features of variable intensity, associated malformations and an increased risk of subsequent acquired diseases.The diagnosis of certainty is established after ...

The Pituitary Stem Interruption Syndrome: A Neonatal Pathology not to be Ignored

Ould Mohand Ouamer , Fernane Leila , Sebar Khadidja , Lebane Djamil

Introduction: Pituitary stem interruption syndrome (PSIS) is a congenital abnormality of the pituitary gland responsible for pituitary insufficiency. Its prevalence is unknown but about 1000 cases have been reported to date. It is characterized by a triad associating a very fine or interrupted pituitary stalk, an ectopic posthypophysis (PH) or absent and a hypoplasia of the anterior pituitary, visible on the MRI. The etiology of PSIS remains unknown.<p cla...
