IASO applies a series of screening tests on newborns as a package which includes Metabolic Diseases, Otoacoustic Emissions, Ophthalmological Examination, Hip Ultrasound Screening, Cardiology exam & echocardiogram and Pediatric endocrinology assessment
and developmental test for small – for – gestational age (SGA) newborns. Hip ultrasound is performed one (1) month after childbirth at IASO CHILDREN’S HOSPITAL, by making an appointment at +30 210 638 3070 and +30 210 638 3072.
Screenings for metabolic diseases include: Cystic Fibrosis (IRT), Congenital Adrenal Hyperplasia (17-OH-Progesterone) Deficiency Biotinidase (partial and total), organic aciduria, Amino Acid Absorption Deficiency, Deficiency Fatty Acid Absorption. The
overall incidence is 1:1500 children.
What is neonatal screening?
The neonatal screening takes place on the second to fourth day after birth. The purpose of the neonatal screening is to detect infants who are 'suspect' for the presence of serious diseases, where early diagnosis allows clinical improvement and/or avoidance
of severe clinical symptoms such as neurological, digestive, respiratory and other disorders. The Institute of Child Health provides control for only four diseases: phenylketonuria, deficiency of glucose-6-phosphate dehydrogenase (G6PD), congenital
hypothyroidism and galactosemia.
What is the expanded neonatal screening?
The extended neonatal screening enables the detection of more serious diseases, some of which occur at a relatively high frequency in the Greek population, and some of which are rarer.
Specifically, high frequency diseases include cystic
fibrosis, Biotinidase deficiency and congenital adrenal hyperplasia. Every year, 50-60 children are born suffering from Cystic Fibrosis -a disease affecting the function of many organic systems but the main clinical manifestations are detected in
the respiratory and digestive system. Early diagnosis of this disease promotes the adoption of appropriate measures and the optimization of clinical symptoms in order to ensure the patient’s better quality of life.
As for the rarer diseases,
it regards to 40 metabolic disorders (deficiency of amino acids, fatty acids and/or organic acids), the early diagnosis of which can prevent the onset of serious health problems such as mental retardation, hearing loss, visual disturbances, and seizures.
Only in case of pathologic findings are you informed by IASO and sent the results to the address specified upon admission.
It is a simple, fast, painless screening test conducted in all modern maternity clinics abroad. During the examination, continuous rhythmic sounds are emitted to the neonate and the ear’s acoustic response is recorded via a special device connected to
a computer. The ideal time for the performance of this testing is during the first days after birth, when neonates are asleep for the biggest part of the day. The examination can also be carried out during sleep, so the baby is not aware of it. To a significant
extent, the presence of otoacoustic emissions is indicative of normal hearing.
Neonatal hypoacusia (hearing loss) frequency accounts for 3-4‰ of all newborns whereas severe hypoacusia (deafness) is present in 1‰. It is worth mentioning that
the aforementioned rates also include congenital hypoacusia family history-free children. Early detected and timely managed hypoacusia during the first weeks of a neonate’s life is of great importance to a child’s speech development and cognitive and
mental progress.
For this reason, the OAEs screening test, performed in all neonates in the USA and the countries of West Europe, is similarly applied to all neonates born in IASO Clinic, for the past twenty years.
It is worth noting that IASO is the first Maternity Clinic in Greece to apply this examination universally. IASO Hospital’s program is one of the largest internationally.
All the above are according to WHO recommendations. The recording of the screening test remains in the hospitalization file and its results are written down on the personal child health record (p. 15).

The ophthalmological examination performed at IASO Maternity Hospital investigates the possible presence of congenital abnormalities of the eyes and eyelids of the newborn. It also examines the possible presence of congenital diseases such as congenital cataract, glaucoma, congenital optic nerve and retina anomalies or the existence of an inflammation in the ocular fundus (eye ground) (e.g., toxoplasmosis) or conjunctiva (e.g. conjunctivitis). Early diagnosis and treatment of some of these diseases can be life-saving for the baby's eyesight. The recording of the examination remains in the medical file and its results are recorded in the child’s Health Book (p. 15).

The developmental dysplasia of the hip, formerly widely known as congenital hip dislocation is a common condition, present at 0.1% of births. It is a multifactorial condition; the treatment is simple, if detected early (before 6 months). At a significant proportion, it is diagnosed with clinical preventive control of the hips by a pediatrician or an orthopedic specialist, yet, a large proportion remains undiagnosed for several months.
Via the ultrasound, the morphology of the hip joint is depicted and the so-called “silent dysplasia” can be early diagnosed, leading to an early treatment. In the European countries that have implemented the universal screening of hip sonography in neonates, the rate of late diagnosed cases of dysplasia has almost disappeared and, by extension, complicated surgeries, too.

Heart conditions (congenital and inherited) are not rare in neonates, since 10 to 12 in 1000 neonates are born with some type of heart defect. Most of these conditions (65%) will need to be treated (usually surgically) during the first year of their lives. Early diagnosis and treatment can improve dramatically the final outcome.
In the context of screening tests for neonates, IASO introduces the Cardiology Exam & Echocardiogram, performed by experienced and qualified Pediatric Cardiologists.
It is a simple exam that is carried out at the neonatal ward of the Hospital. It complements the prenatal cardiology exam, and offers parents and the treating pediatrician the chance to rule out neonatal heart problems.
If a heart problem is detected, the parents are fully briefed and are given suitable treatment and monitoring instructions.

According to international literature, low birth weight newborns have a statistically higher chance of manifesting developmental abnormalities and metabolic disorders later on in life, including:
For this reason, they require regular monitoring and early treatment.
For this reason, they require regular monitoring and early treatment. Monitoring is performed by a Pediatric Endocrinology Specialist and an experienced Pediatrician.
