Down syndrome (DS) is characterized by a higher incidence of congenital hypothyroidism (CH) and a high prevalence of subclinical hypothyroidism (SH) early in life. Children and adults with DS have an increased risk of developing autoimmune thyroid disease, however CH and early SH cannot be explained by thyroid autoimmunity. The etiology of CH and early SH in DS remains to be elucidated. Considering the recently discovered genome-wide transcriptional and epigenetic alterations ...

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 ...

Background: Newborn (NB) screening programs show a wide variation in congenital hypothyroidism (CH) incidence along the years.Objective and hypotheses: To describe CH incidence, etiology, associated malformations and Down Syndrome (DS) in children detected by our NB Screening Program. To search differences between permanent CH (PCH) and transient forms (TCH).Method: We analyzed NB with positive screening results referred between A...

Background: Over the years special screening procedures for preterm and twin babies (re-screening at 2–4 weeks of life) have been adopted by many screening laboratories worldwide. However, no extensive studies have been performed to verify how many co-twins with negative test at first screening (3–5 days) become positive at re-screening, and the utility of a long-term follow-up also in co-twin with negative test at screening and re-screening.Ob...

Background: The intelligence prognosis of congenital hypothyroidism (CH) is remarkably improved by early detection and optimal levothyroxine (LT4) treatment. Some groups have reported that initial LT4 overtreatment results in a subsequent decrease of cognitive function. In universal guidelines, an initial dose of 10–15 μg/kg per day of LT4 is recommended. However, there are cases of LT4 overdosing.Obj...

Background: Congenital hypothyroidism (CH) is a common condition that occurs in ~1:3000–4000 live births and is one of the most common preventable cause of mental retardation with an early diagnosis and prompt pharmacological treatment. Neonatal screening has abolished this disease but 10% of children originally diagnosed with CH will have a transient form of the disorder and this percentage is increased during the last years due to a lowering of cut-off.<p class="abs...

Background and Aim: Congenital hypothyroidism (CH) is a well-known condition. Nevertheless, recent questions in clinical practice, especially in neonatal intensive care setting, prompted us to review the natural history of CH in our cohort.Methods: This is a retrospective, observational study collecting anamnestic, anthropometric (height SDS, BMI SDS), diagnostic (TSH, fT4, thyroid ultrasound) and therapeutic data (dose ...

Introduction: Consensus guidelines (2021) state that a second dry blood spot (DBS) should be considered for newborn screening (NBS) in preterms (delayed TSH rise).Objective: To evaluate the diagnostic yield of an NBS strategy including a second DBS at 14 days in preterms.Material and Methods: Retrospective study of 2 cohorts. Cohort 1: live births <37 weeks of gestational age (G...

Background: Congenital hypothyroidism (CH) is a treatable thyroid hormone deficiency that causes intellectual disabilities and growth deficiency if not detected and treated early.Material and Methods: We retrospectively analyzed the medical records of 22 patients, 13 (59%) females and 9 (41%) males, with positive CH screening at birth and confirmed by TSH & FT4 serum concentrations measurements, thyroid ultrasound an...

Osteogenesis imperfecta, also known as "brittle or glassy bone disease", is a connective tissue disease that occurs as a result of quantitative and qualitative changes in type 1 collagen. The disease is transmitted in an autosomal dominant way and the incidence is 1:20,000.The aim: of the study was to evaluate the clinical characteristics and treatment of children diagnosed with osteogenesis imperfecta in children.<p class=...
