A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency. Clinical symptoms include severe MENTAL RETARDATION, impaired skeletal development, short stature, and MYXEDEMA.
A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA.
Defective development of the THYROID GLAND. This concept includes thyroid agenesis (aplasia), hypoplasia, or an ectopic gland. Clinical signs usually are those of CONGENITAL HYPOTHYROIDISM.
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.
A glycoprotein hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Thyrotropin stimulates THYROID GLAND by increasing the iodide transport, synthesis and release of thyroid hormones (THYROXINE and TRIIODOTHYRONINE). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; LUTEINIZING HORMONE and FSH), but the beta subunit is unique and confers its biological specificity.
Blood tests used to evaluate the functioning of the thyroid gland.
A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.
Natural hormones secreted by the THYROID GLAND, such as THYROXINE, and their synthetic analogs.
An infant during the first month after birth.
Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC).
A T3 thyroid hormone normally synthesized and secreted by the thyroid gland in much smaller quantities than thyroxine (T4). Most T3 is derived from peripheral monodeiodination of T4 at the 5' position of the outer ring of the iodothyronine nucleus. The hormone finally delivered and used by the tissues is mainly T3.
A dehydrated extract of thyroid glands from domesticated animals. After the removal of fat and connective tissue, the extract is dried or lyophilized to yield a yellowish to buff-colored amorphous powder containing 0.17-0.23% of iodine.
A hemeprotein that catalyzes the oxidation of the iodide radical to iodine with the subsequent iodination of many organic compounds, particularly proteins. EC 1.11.1.8.
A nonmetallic element of the halogen group that is represented by the atomic symbol I, atomic number 53, and atomic weight of 126.90. It is a nutritionally essential element, especially important in thyroid hormone synthesis. In solution, it has anti-infective properties and is used topically.

Cell surface proteins that bind pituitary THYROTROPIN (also named thyroid stimulating hormone or TSH) and trigger intracellular changes of the target cells. TSH receptors are present in the nervous system and on target cells in the thyroid gland. Autoantibodies to TSH receptors are implicated in thyroid diseases such as GRAVES DISEASE and Hashimoto disease (THYROIDITIS, AUTOIMMUNE).
Any of six membrane-covered openings between the CRANIAL SUTURES in the incompletely ossified skull of the fetus or newborn infant. The fontanelles normally close sometime after birth.
A group of autosomal recessive disorders marked by a deficiency of the hepatic enzyme PHENYLALANINE HYDROXYLASE or less frequently by reduced activity of DIHYDROPTERIDINE REDUCTASE (i.e., atypical phenylketonuria). Classical phenylketonuria is caused by a severe deficiency of phenylalanine hydroxylase and presents in infancy with developmental delay; SEIZURES; skin HYPOPIGMENTATION; ECZEMA; and demyelination in the central nervous system. (From Adams et al., Principles of Neurology, 6th ed, p952).
Blood proteins that bind to THYROID HORMONES such as THYROXINE and transport them throughout the circulatory system.
A thioureylene antithyroid agent that inhibits the formation of thyroid hormones by interfering with the incorporation of iodine into tyrosyl residues of thyroglobulin. This is done by interfering with the oxidation of iodide ion and iodotyrosyl groups through inhibition of the peroxidase enzyme.
Inorganic binary compounds of iodine or the I- ion.
Predeciduous teeth present at birth. They may be well formed and normal or may represent hornified epithelial structures without roots. They are found on the gingivae over the crest of the ridge and arise from accessory buds of the dental lamina ahead of the deciduous buds or from buds of the accessory dental lamina. (From Jablonski, Dictionary of Dentistry, 1992)
The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)

Pertechnetate scintigraphy in primary congenital hypothyroidism. (1/303)

Primary congenital hypothyroidism (PCH) is currently detected effectively by heel-stick screening. When elevated thyrotropin (TSH) and/or decreased T4 are found in the blood of neonates, they are recalled, values are confirmed in venous blood and thyroxine replacement therapy (TRT) is immediately instituted, thus cretinism or severe retardation is prevented. However, in a significant percentage of neonates with abnormal blood levels of T4 or TSH, the disorder is transient. To help determine the exact cause of PCH and the possibility of transient PCH, pinhole thyroid imaging is performed 30 min after an intravenous injection of 18.5 MBq (500 microCi) 99mTc-pertechnetate (TcPT). Patients with a nonvisualized gland or patients with images suggesting dyshormonogenesis are reevaluated at age 3-4 y to exclude transient PCH. METHODS: To define the role of TcPT imaging in determining the exact etiology of PCH and the possibility of its being transient, we reviewed data from 103 neonates with PCH who had scintigraphy in our laboratory between 1970 and 1996 and we correlated the results with clinical outcome. RESULTS: Four patterns of thyroid scintigrams were recognized and these determined patient classification: (a) normal in 7 patients with false-positive heel-stick screening but normal venous blood hormone levels; (b) hypoplasia-ectopia in 32 patients requiring lifelong TRT; (c) nonvisualization in 35 patients-32 with agenesis requiring lifelong TRT and 3 with fetal thyroid suppression by maternal antibodies whose TRT was discontinued at a later age; and (d) dyshormonogenesis (markedly increased TcPT concentration) in 29 patients-25 with permanent PCH requiring lifelong TRT and 4 with transient PCH in whom TRT was discontinued. Of the 25 patients with dyshormonogenesis, 12 belonged to five families with two or three siblings having the same disorder. CONCLUSION: TcPT thyroid scintigraphy in the neonate with PCH provides a more specific diagnosis, is useful for selecting patients for re-evaluation to uncover transient PCH and discontinue TRT and defines dyshormonogenesis, which is familial and requires genetic counseling. It is also cost-effective.  (+info)

Structural defects of a Pax8 mutant that give rise to congenital hypothyroidism. (2/303)

Pax proteins are transcriptional regulators that play important roles during embryogenesis. These proteins recognize specific DNA sequences via a conserved element: the paired domain (Prd domain). The low level of organized secondary structure, in the free state, is a general feature of Prd domains; however, these proteins undergo a dramatic gain in alpha-helical content upon interaction with DNA ('induced fit'). Pax8 is expressed in the developing thyroid, kidney and several areas of the central nervous system. In humans, mutations of the Pax8 gene, which are mapped to the coding region of the Prd domain, give rise to congenital hypothyroidism. Here, we have investigated the molecular defects caused by a mutation in which leucine at position 62 is substituted for an arginine. Leu62 is conserved among Prd domains, and contributes towards the packing together of helices 1 and 3. The binding affinity of the Leu62Arg mutant for a specific DNA sequence (the C sequence of thyroglobulin promoter) is decreased 60-fold with respect to the wild-type Pax8 Prd domain. However, the affinities with which the wild-type and the mutant proteins bind to a non-specific DNA sequence are very similar. CD spectra demonstrate that, in the absence of DNA, both wild-type Pax8 and the Leu62Arg mutant possess a low alpha-helical content; however, in the Leu62Arg mutant, the gain in alpha-helical content upon interaction with DNA is greatly reduced with respect to the wild-type protein. Thus the molecular defect of the Leu62Arg mutant causes a reduced capability for induced fit upon DNA interaction.  (+info)

Early cellular abnormalities induced by RET/PTC1 oncogene in thyroid-targeted transgenic mice. (3/303)

The RET/PTC1 oncogene, a rearranged form of the RET proto-oncogene, has been reported to be associated with human papillary thyroid carcinomas. We have shown that targeted expression of RET/PTC1 in the thyroid gland leads to the development of thyroid carcinomas in transgenic mice with histologic and cytologic similarities to human papillary thyroid carcinoma. To further investigate how RET/PTC1 expression contributes to the pathogenesis of papillary thyroid tumor, the time of tumor onset and the early phenotypic consequences of RET/PTC1 expression in thyrocytes were determined. All high copy transgenic mice developed bilateral thyroid tumors as early as 4 days of age. At embryological days 16-18, increased proliferation rate, distorted thyroid follicle formation and reduced radioiodide concentrating activity were identified in transgenic embryos. The reduced radioiodide concentrating activity was attributed to decreased expression of the sodium-iodide symporter. Our study showed that RET/PTC1 not only increased proliferation of thyrocytes, it also altered morphogenesis and differentiation. These findings provide a model for the role of RET/PTC1 in the formation of abnormal follicles with reduced iodide uptake ability observed in human papillary thyroid carcinoma.  (+info)

Intellectual outcome at 12 years of age in congenital hypothyroidism. (4/303)

BACKGROUND: The intellectual outcome in children with congenital hypothyroidism detected by neonatal screening is generally good; however, subtle neurological dysfunctions, subnormal IQ, or both, have been reported. OBJECTIVE: To evaluate the intellectual outcome in 12-year-old patients with congenital hypothyroidism, detected by neonatal screening, in an attempt to identify factors that may affect intellectual development. METHODS: The intelligence quotient (IQ) of 40 children with congenital hypothyroidism was evaluated at 12 years of age, using the Wechsler Intelligence Scale for Children -- Revised, and compared with the IQ of 40 healthy siblings (control group). RESULTS: The mean IQ score (88.4+/-13.1) was not significantly different from that of the control group (93.4+/-10.7). Thirteen patients showed subnormal IQ score (72.4+/-4.9) compared with their siblings (86.7+/-9.6; P<0.0001) and with the other patients (96.1+/-9.6; P<0.0001). The low IQ score was associated with lower serum concentrations of thyroxine at diagnosis, poor treatment compliance during follow-up and lower familial IQ. Interviews with parents of children with congenital hypothyroidism revealed that a refusal to acknowledge the disease was linked to poor attention to the child's emotional life and to poor treatment compliance in some cases (11%). CONCLUSION: Even though the mean IQ score in patients with congenital hypothyroidism falls within normal for the control population, low IQ scores may be present in patients with severe hypothyroidism, inadequate compliance to replacement therapy during follow-up and poor parental pedagogic attitude.  (+info)

Iodine and neuropsychological development. (5/303)

The establishment of the essential link among iodine deficiency, thyroid function and brain development has emerged from a fascinating combination of clinical, epidemiologic and experimental studies. The central human phenomenon that focuses this relationship is the condition of endemic cretinism, described from the Middle Ages and characterized in its fully developed form by severe brain damage, deaf mutism and a spastic state of the hands and feet. The demonstration of the prevention of cretinism in a double-blind controlled trial with injections of iodized oil in Papua New Guinea (1966-1970) established the causal role of iodine deficiency in cretinism by an effect on the developing fetal brain. Cretinism could not be prevented unless the iodized oil was given before pregnancy. Iodine deficiency is now regarded by the WHO as the most common preventable cause of brain damage in the world today, with at least 30 million suffering from this preventable condition. Since 1986 the international NGO, the International Council for Control of Iodine Deficiency Disorders, has worked closely as an expert group with WHO and UNICEF in assisting countries with a program of universal salt iodization for the elimination of iodine deficiency as a cause of brain damage by the year 2000. In 1996, WHO reported that 56% of the population of 83 developing countries now had adequate access to iodized salt. This represents an increase of 750 million since 1990 with protection of 12 million children.  (+info)

Thyroid stimulating hormone levels in cord blood are not influenced by non-thyroidal mothers' diseases. (6/303)

CONTEXT: Screening programs not only offer the opportunity to trace and treat almost all cases of congenital hypothyroidism but also mean large savings to the health system. However, carefully planned strategies are necessary to extend their benefits and reduce costs. OBJECTIVE: To determine the possible influence of maternal diseases that affect maternal-fetal placenta dynamics on primary thyroid stimulating hormone (TSH) screening for congenital hypothyroidism. DESIGN: Prospective non-randomized clinical trial with at least 3 months of follow-up. SETTING: A public university referral center [CAISM/Hospital das Clinicas, Faculty of Medicine, University of Campinas, Campinas, SP]. PARTICIPANTS: 415 neonates divided into 5 groups: eighty-three infants born from cardiac mothers; 98 from mothers that had toxemia; 54 of the mothers had diabetes mellitus; 40 were HIV positive and 140 had no diseases. INTERVENTION: All newborns had cord blood samples collected on filter paper at birth. MAIN MEASUREMENTS: TSH was measured from dried blood spots using a homemade immunofluorescence assay (sensitivity in dried blood spots = 0.1 mU/L). RESULTS: There was no significant difference in the mean TSH levels among the 5 groups. Moreover, TSH levels were around 5 mU/L in 48% of the newborns, indicating that our region is severely deficient in iodine. CONCLUSIONS: Our results indicate that primary TSH screening programs using cord blood are not affected by maternal diseases. We suggest that, besides its technical advantages over heel punctures with T4 primary approaches, neonatal screening using primary cord blood TSH may also be used as a monitoring tool for evaluation and control of iodine deficiency disorders (IDD).  (+info)

Novel mutations of the thyroid peroxidase gene in patients with permanent congenital hypothyroidism. (7/303)

OBJECTIVE: It is suggested that iodide organification defects account for 10% of all cases with congenital hypothyroidism (CH). One candidate gene for these defects is the thyroid peroxidase (TPO) gene. DESIGN: Exons 2, 8-10 and 14 of the TPO gene were examined in 30 patients with permanent CH without a family history of CH. This group was characterized by the presence of an orthotopic thyroid gland and elevated TSH levels. METHODS: The mutational screening was performed by single-strand conformational polymorphism followed by sequence analysis of fragments with abnormal migration patterns and by restriction enzyme analysis. RESULTS: In four patients we were able to identify mutations on both alleles which have not been described so far. One patient was a carrier of a new homozygous point mutation in exon 9 resulting in an exchange from Leu to Pro at codon 458. Another patient was found to be compound heterozygous for two mutations, a 20 bp duplication in exon 2 and a new mutation in exon 9 (Arg491His). Two brothers of consanguineous parents showed a homozygous T deletion in exon 14 at position 2512. CONCLUSIONS: Our findings confirm the genetic heterogeneity of TPO defects and support the suggested prevalence of organification defects.  (+info)

Longitudinal growth, sexual maturation and final height in patients with congenital hypothyroidism detected by neonatal screening. (8/303)

OBJECTIVE: To evaluate longitudinal growth, pubertal development and final height in patients with congenital hypothyroidism (CH) detected by a neonatal screening programme, and to identify factors potentially affecting growth outcome. PATIENTS: Fifty-five patients (41 females) detected by neonatal screening and followed longitudinally from the time of diagnosis and treatment (25+/-5 days) up to the age of 17+/-0.5 years were evaluated retrospectively. RESULTS: Pubertal development began and progressed normally in both males and females. In boys, a testicular volume of 4 ml was reached at 11.3+/-1.0 years. In girls breast enlargement (B2) occurred at a mean age of 10.3+/-1.2 years and the mean age of menarche was 12.5+/-1.2 years. The onset and the progression of puberty were independent of the aetiology, the severity of CH and the timing of the beginning of treatment. Girls treated with an initial amount of L-thyroxine (L-T4) greater than 8 microg/kg per day showed an earlier onset of puberty (B2 9.4+/-0.9 years; menarche 11.5+/-0.8 years) compared with girls treated with a lower initial dose of L-T4 (B2 10.5+/-1.2 years; menarche 12.6+/-1.2 years; P<0.02). However, both groups attained a similar final height (-0.1+/-1.0 SDS and 0.4+/-1.0 SDS, respectively), which in both cases was above the target height (P=0.03). All the patients in the study attained a mean final height (0.1+/-1.1 SDS) within the normal range for the reference population and above the target height (-0.9+/-0.9 SDS, P<0.0001). No significant relationship was found between final height and severity of CH at diagnosis, initial L-T4 dosage or aetiology of the defect. Patients with ectopic gland, thyroid aplasia or in situ gland attained a similar mean final height (0.1+/-1.1 SDS, 0.5+/-1.0 SDS and -0.5+/-1.0 SDS, respectively), which was in all cases greater than target height (-1.0+/-0.9, -0.6+/-0.8, -0.9+/-0.8 respectively; P<0.05). CONCLUSIONS: Our results suggest that conventional management of children with CH detected by neonatal screening leads to normal sexual development and normal adult height, and that the major factor determining height in these children is familial genetic growth potential.  (+info)

Newborn screening for primary congenital hypothyroidism is part of the U.S. Recommended Uniform Screening Panel (1,2). Untreated congenital hypothyroidism can result in cognitive impairment and growth complications (decreased height/length). Initial newborn screening for congenital hypothyroidism is typically performed 24-48 hours after birth. Fourteen states, including Utah, perform a routine second screen at approximately 2 weeks of age.* During 2010-2016, a total of 359,432 infants in Utah were screened for congenital hypothyroidism, and 130 cases were diagnosed; among these, 98 had an abnormal first screen, and 25 had an abnormal second screen (seven infants were excluded because of missing data). A retrospective examination of Utahs screening data indicated that 20% of congenital hypothyroidism cases could not have been efficiently identified by a single screen alone. This study highlights the utility of a two-screen process and demonstrates that differential cutoff values for the first ...

Congenital Hypothyroidism usually results when a baby is born without a thyroid gland, but there are many other causes of this disorder. Congenital Hypothyroidism is treated the same as hypothyroidism, with thyroid replacement hormone, Levothyroxine. It is crucial for these babies to be diagnosed within a few days of birth by a newborn screening (heel prick) test as any delay can lead to loss of IQ. As babies grow, monitoring is necessary to adjust Levothyroxine dosage and to monitor growth and development. Ensuring Pathology tests are performed in the correct manner at essential..

BackgroundCongenital hypothyroidism (CH) is one of the most common preventable causes of mental retardation. One important challenge in understanding the epidemiology of CH is that some newborns will have transient CH, a temporary depression of thyroid hormone concentrations that can last from several days to several months. Studies from other countries have reported that 10 to 15% of children treated for CH ultimately prove not to need treatment past 3 years of age to maintain normal hormone concentrations, and thus have transient hypothyroidism. The purpose of this study was to determine the prevalence of permanent and transient congenital hypothyroidism in Fayoum, Egypt. MethodsCases detected by Fayoum neonatal screening program (NSP) between January 2003 and December 2011, and followed up at health insurance center were included. Permanent or transient CH was determined using results of thyroid function tests. ResultsOf the 248 patients diagnosed primarily with CH by NSP; 204 (82.3%) patients
Context: Mutations in the DUOX2 gene have been associated with transient or permanent congenital hypothyroidism due to a dyshormonogenic defect. Objective: This study aimed to verify the prevalence of DUOX2 mutationsandthe associated clinical features in children selected by criteria supporting a partial iodide organification defect (PIOD). Patients and Methods: Thirty children with PIOD-like criteria were enrolled and genotyped. A detailed clinical characterization was undertaken together with the functional analysis of the DUOX2 variations and the revision of the clinical and molecular data of the literature. Results: In this large selected series, the prevalence of the DUOX2 mutations was high (37%). We identified 12 missense variants, one splice site, and three frameshift DUOX2 mutations. Functional analyses showed significant impairment of H2O2 generation with five missense variants. Stopcodon mutants were shown to totally abolish DUOX2 activity by nonsense-mediated RNA decay, exon ...
The purpose of this study was to estimate the incidence of cases with transient and permanent CH in Hamadan, Iran. In our study, the incidence of CH is found to be 1/1250 of live birth. Of the 164 patients 105 cases (64 %) were proven to have permanent CH and 59 cases (36%) had transient hypothyroidism. The frequency of CH as well as transient hypothyroidism was relatively high in our study. Our data confirm the findings of previous studies regarding the high prevalence of hypothyroidism in Iran (15-18). For example, a meta-analysis study by Veisani et al. (18) revealed that the overall incidence of CH in Iran is 2/1000 of live births. Since the most common etiology of CH was dyshormonogenesis as indicated in the studies conducted by Hashemipour et al. (9) and Karamizadeh et al. (19) in Iran, a relatively high rate of parental consanguinity (25%) among infant with congenital hypothyroidism could account for the increased incidence of CH in our region. In support of the previous data, we also ...
Anaesthetic management of the premature infant is a challenge. This is owing to the immaturity of his or her organ systems and the possible presence of sequelae of premature birth, such as broncho pulmonary dysplasia, apnoea, patent ductus arteriosus and intra ventricular haemorrhage. The premature infant is at risk of developing postoperative apnoea, hypothermia and hypoglycaemia until his or her post gestational age is more than 60 weeks. Conditions such as congenital bilateral cataract and congenital hypothyroidism may be associated with other birth defects and syndromes. Recommendations for early cataract surgery may necessitate an aesthetising premature infants with post conceptional ages less than 60 weeks, or those who have had recently diagnosed medical conditions, such as hypothyroidism. We describe the anaesthetic considerations in a, so far, unreported scenario of a premature infant with bilateral congenital cataract and congenital hypothyroidism who presented for cataract surgery.
Introduction Congenital hypothyroidism (CH) is common, affecting between 1:3,000 and 4,000 newborn infants. Unrecognized or inadequately treated, CH leads to mental retardation. Newborn screening has made it possible to identify affected infants at a very early age, allowing thyroid therapy to be initiated usually within two weeks of birth. As a result of early diagnosis and appropriate treatment, many children with CH have normal cognitive development. The American Academy of Pediatrics (AAP) and the European Society for Pediatric Endocrinology (ESPE) have published guidelines to assist physicians in the appropriate evaluation and treatment of children with CH. Although early detection, correct diagnosis and timely treatment are critical to facilitate the best outcomes, little is known about provider practices when confronted with infants with congenital hypothyroidism. We, therefore, conducted a survey of pediatric endocrine providers to categorize beliefs and clinical practices. Methods An on-line
With regard to blood draws, I have been quoted as saying it gets easier…. Its true. It gets easier. That doesnt mean they arent still hard.. Yesterday, both of my boys needed to go in for their routine blood draw to check their thyroid levels, as do all children with congenital hypothyroidism. Now that they are older, they only go every 6 months (unless there is an issue, then more frequently). Just enough time to forget they have to ever go again. I picked up my oldest from school. My youngest was already in the car. With my youngest, the less time he has to ponder the thought of having his blood drawn, the better. At the last draw, they both did well. No tears. This is a victory. For any other parent who has a child with a chronic illness (like congenital hypothyroidism), you know what I mean. You too have endured kicking, screaming, biting, fighting and everything else your child has thrown at you and the other people in the lab. You too have watched your child meltdown at the mere ...

Hypothyroidism from iodide transport deficiency is a rare disease, especially when found in two affected siblings. Treatment with high doses of iodide has been recommended, but no long term results have been reported. Two siblings with congenital hypothyroidism due to total failure to transport iodide have been followed up during twelve and a half years of treatment with oral potassium iodide. Iodine doses varied between 10.3 and 22 mg/day, and serum total iodine concentrations between 100 and 210 micrograms/dl. Total triiodothyronine (T3), thyroxine (T4) and free T4 were in the normal range during the time of study. Basal thyroid stimulating hormones (TSH) and maximum TSH response to thyrotrophin releasing hormone (TRH) were also in the range of normal values. These data along with clinical findings confirmed the potential usefulness of iodine in hypothyroidism due to complete iodide transport defect.. ...
Subjects who are heterozygous for thyroid stimulating hormone receptor (TSHR) gene mutations present various phenotypes that range from euthyroid to hyperthyrotropinemia. Similarly, heterozygous dual oxidase 2 (DUOX2) gene mutations result in variable phenotypes, such as transient congenital hypothyroidism, subclinical hyperthyrotropinemia, and euthyroid in children. Here, we describe an 8-year-old boy who had normal newborn screening results, but who developed nonautoimmune hypothyroidism at the age of 1 year and 8 months of age. He was heterozygous for previously reported R450H-TSHR mutation and heterozygous for a novel double mutant allele A1323T-DUOX2 and L1343F-DUOX2. He needed levothyroxine (l-T4) replacement therapy to keep serum TSH levels within normal limits; l-T4 dose of 2.01-2.65 μg/kg/day corresponded to the dose taken by children homozygous for R450H-TSHR and by children with permanent congenital hypothyroidism. Therefore, the coexistence of a heterozygous TSHR mutation and a ...
We aim to determine long-term intellectual outcome of adolescents with early high-dose treated congenital hypothyroidism (CH). Sixty-three prospectively followed children with CH were assessed at age of 14 y with the Wechsler Intelligence Scale for Children-Revised and compared with 175 healthy controls. Median age at onset of treatment was 9 d (range 5-18 d) and median starting dose of levothyroxine (L-T4) was 14.7 microg/kg/d (range 9.9-23.6 microg/kg/d). Full-scale intelligence quotient (IQ) was significantly lower than in controls after adjustment for socioeconomic status (SES) and gender (101.7 versus 111.4; p , 0.0001). Children with athyreosis had a lower performance IQ than those with dysgenesis (adjusted difference 7.6 IQ scores, p , 0.05). Lower initial thyroxine (T4) levels correlated with poorer IQ (r = 0.27, p = 0.04). Lower SES was associated with poorer IQ, in particular in children with CH (interaction, p = 0.03). Treatment during childhood was not related to IQ at age 14 y. ...
When the thyroid gland does not make enough thyroid hormone it is called hypothyroidism. Congenital hypothyroidism is when the disorder is present in a baby at birth. If not treated, it can lead to serious health problems. The thyroid is a gland. Its located in the neck, just below the voice box. The thyroid gland makes thyroid hormone. This hormone helps control the metabolism. This is the rate at which every part of the body functions. Thyroid hormone keeps the metabolism at a healthy pace. This helps the brain, heart, muscles, and other organs work well. A normal metabolism also helps ensure a healthy temperature, heart rate, energy level, and growth rate. If a baby does not make enough thyroid hormone, it can cause serious problems such as mental disability, growth delays, or loss of hearing. ...

Age- and method-dependent plasma TSH reference intervals are essential for the diagnosis and management of congenital hypothyroidism. However, accurate reference intervals for plasma TSH have not been adequately defined due to the difficulties in obtaining samples from a healthy paediatric population. To overcome the difficulties in generating such intervals we estimated method-dependent plasma TSH upper-reference intervals by determining the blood spot TSH upper-reference interval from newborn blood spot TSH screening data (N = 10,697) and then derived method-dependent conversion factors for blood spot TSH to plasma TSH concentration from paired-blood spot and plasma TSH measurements. The upper reference interval for blood spot TSH of 3.04 mU/L was obtained from the 97.5th centile of the selected data. Using experimentally-derived conversion factors, estimates of plasma TSH upper reference intervals of 7.6, 6.3, 7.3, 8.3 and 6.5 mU/L were obtained for the Siemens Centaur, Abbott Architect, ...
Objectives: -To determine children diagnosed with central congenital hypothyroidism (CCH) by a screening program using TSH and total T4 between May 2016 and January 2019.. -To analyze the characteristics of the disease in these children.. Material and Methods: During the time of the study, 14.743 newborns have been screened. Cut-off points are used for TSH ≥10MU/ml and T4 6 and 20 mg/dl as lower and upper limits.. When the result was positive, a second sample was performed on filter paper and if the second sample was also positive, the patient was sent to the Pediatric Endocrinology Unit to confirm the results. Diagnosed of CCH was made with the combination of low FT4 and inappropriate low TSH. If the patient was diagnosed with CCH, hormonal studies, skull MRI and genetic analyses were performed.. Results: For total T4 values, first simple screening was positive in 112 patients (076% of total). Of these cases, the second sample continued to be positive in 17 cases (011% of the total), in ...
Congenital hypothyroidism is inadequate thyroid hormone production in newborn infants. This can occur because of an anatomic defect in the gland, an inborn error of thyroid metabolism, or iodine deficiency.
OBJECTIVE: To evaluate the vocal characteristics of a group of children with congenital hypothyroidism (CH) and the association of these characteristics with the childrens clinical, laboratory, and therapeutic profiles. MATHERIAL AND METHODS: Observational, analytical, cross-sectional study including 200 prepubertal children, of whom 100 had CH (study group [SG]) and 100 had no CH (control group [CG]). The following parameters were evaluated: 1) history (identification, complaints, and interfering variables), 2) auditory-perceptual and acoustic evaluation (samples analyzed by a group of specialists, and objectively by a computer program), 3) self-assessment scores in the Pediatric Voice-Related Quality-of-Life (PVRQoL) survey, 4) laryngological evaluation (presence or absence of laryngeal lesions and data regarding glottal closure), and 5) medical records (CH etiology, age at treatment initiation, disease severity at diagnosis, treatment quality, and thyroid function tests on the day of the ...
The zebrafish has recently emerged as a new, genetically tractable model for investigating the molecular mechanisms underpinning thyroid organogenesis and function (Alt et al., 2006; Elsalini and Rohr, 2003; Guillot et al., 2016; McMenamin et al., 2014; Trubiroha et al., 2018; Wendl et al., 2002). Although a recent report described the larval phenotype associated with CRISPR generated bi-allelic loss-of-function duox mutations in F0 zebrafish (Trubiroha et al., 2018), there have been no prior reports describing the phenotypic consequences of fully characterised duox alleles in adult zebrafish. This is despite the fact that mutations in DUOX2 and DUOX1 have been shown to be associated with congenital hypothyroidism in humans for more than a decade (Aycan et al., 2017; Donkó et al., 2014; Jin et al., 2014; Johnson et al., 2007; Kizys et al., 2017; Tonacchera et al., 2009; Vigone et al., 2005). Here, we describe a comprehensive assessment of the adult phenotypes associated with homozygosity of two ...
I do not connect stunted thumbs and congenital hypothyroidism, but maybe another reader can help. Regarding the blood hormone levels, certainly it seems that the patient has been under excessive thyroid hormone dosage, and needs to be reduced gradually to a level that keeps the TSH preferrably around 1-1.5, and the freeT4 in the high normal range. It probably will take many months for the pituitary to return to normal as you lower the dose. Regarding the future, I guess you wait and see. If the patient was untreated for 18 months after birth, that suggests a major developmental problem unless there was in fact significant endogenous thyroid hormone production at that time..

CONTEXT: Patients with thyroidal congenital hypothyroidism (CH-T) born in The Netherlands in 1981-1982 showed persistent intellectual and motor deficits during childhood and adulthood, despite initiation of T(4) supplementation at a median age of 28 d after birth. OBJECTIVE: The present study examined whether advancement of treatment initiation to 20 d had resulted in improved cognitive and motor outcome. DESIGN/SETTING/PATIENTS: In 82 Dutch CH-T patients, born in 1992 to 1993 and treated at a median age of 20 d (mean, 22 d; range, 2-73 d), cognitive and motor outcome was assessed (mean age, 10.5 yr; range, 9.6-11.4 yr). Severity of CH-T was classified according to pretreatment free T(4) concentration. MAIN OUTCOME MEASURE: Cognitive and motor outcome of the 1992-1993 cohort in comparison to the 1981 to 1982 cohort was the main outcome measure. RESULTS: Patients with severe CH-T had lower full-scale (93.7), verbal (94.9), and performance (93.9) IQ scores than the normative population (P , 0.05), ...

Iodine is an absolute requirement for maternal, fetal, and postnatal thyroid hormone synthesis. Newborns affected with iodine deficiency have low T4 and high TSH concentrations. With radioisotope imaging, there is avid uptake of 123I by a normally located gland. Treatment involves iodine replacement until normal iodine balance is achieved.. On a global basis, iodine deficiency is the most common cause of transient hypothyroidism, particularly in preterm newborns.15,-,17 Preterm newborns are at higher risk because they have been prematurely deprived of the maternal supply of thyroid hormone, as well as iodine, which leads to inadequate accumulation of iodine in the thyroid gland compared with that of term newborns. Hypothyroidism represents a form of the broader category of iodine-deficiency disorders, which include endemic goiter, hypothyroidism, cretinism, decreased fertility rate, increased infant mortality, and intellectual disability.18 There is extreme variation in iodine deficiency among ...

To the best of the authors knowledge, this is the first Indian study on congenital hypothyroidism in preterm babies. We have described the experience of our unit in screening and evaluating preterm babies with congenital hypothyroidism. In the present study, we have observed a prevalence of 1 in 77 among the 1147 preterm babies screened. Five (33%) out of these cases were missed on initial screening, reiterating the need for repeat testing, and 5 of the screen-positive cases did not have the disease, reiterating the need to follow the standard protocols in preterm babies In our study, we have 15 cases of confirmed congenital hypothyroidism out of 1147 screened preterms, resulting in a prevalence of 1 in 77. This prevalence is much higher than term babies. Our results are comparable to reports by Silva et al. [20], Tylek et al. [11], Bijamia et al. [12], and Korada et al. [13], who reported a prevalence of 1 in 242, 1 in 202, 1 in 128, and 1 in 560, respectively. However, Srinivasan et al. [9] ...

In this study, we have demonstrated that the incidence of CHT has increased significantly in the Republic of Ireland over a 37-year period, without changes in screening thresholds or treatment protocols. The incidence of severe CHT has remained stable, as has the incidence of thyroid ectopy, athyreosis, and hypoplasia. The increase is predominantly seen in milder cases of CHT, which have a normal or hyperplastic gland. Although the increase is seen in milder cases of CHT, the largest increase was seen in infants with serum TSH concentrations between 21 and 100 mU/L at diagnosis, a range in which the need for treatment is not controversial.9 We have also shown in this study that an infant born with trisomy 21 is 26 times more likely than an infant without trisomy 21 to have CHT.. The incidence of CHT that was observed in our study (0.45 cases per 1000 births) is similar to rates that were recently reported in Western Australia (0.35 cases per 1000 live births),2 Quebec (0.40 cases per 1000 live ...
