  • Goiter may be present. T4 is low and TSH is elevated.[slideshare.net]
  • Adrenal ectopic thyroid could present with hypertension, 25 while that in the gallbladder may present with right upper quadrant abdominal pain. 20 Presentation with features of hypothyroidism occurs mainly in children.[hormones.gr]
  • It is also frequently present in newborns with Down syndrome.[elsevier.es]
  • Congenital hypothyroidism (CH) can be defined as a lack of thyroid hormones present from birth. If it is not detected and treated early it is associated with irreversible neurological problems and poor growth.[patient.info]
  • The first was held in La Malbaie in Quebec in the fall of 1979. That meeting was well organized and highly productive. Its proceedings constitute a bible in the field.[books.google.de]
  • Soy falls into a category of foods known as goitrogens —foods and supplements that prevent proper thyroid hormone production and cause the thyroid gland to enlarge.[verywell.com]

  • […] lateral radiograph of the knee may be obtained to look for the distal femoral epiphysis; this ossification center appears at about 36 weeks' gestation, and its absence in a term or postterm infant indicates prenatal effects of hypothyroidism. [16] See Workup[emedicine.medscape.com]


  • Preliminary IQ and neurological data have indicated that screening and early treatment do, in fact, prevent mental retardation.[books.google.de]
  • Treatment Levothyroxine (LT4) is the treatment of choice for CH. The objective is to attain a neurological development and growth corresponding to the genetic potential of the child.[elsevier.es]
  • If this disorder is untreated, studies show a loss of IQ proportionate to the age at which treatment is started: if treatment is started at 0 to 3 months of age, mean IQ is 89 (range: 64–107); if treatment is started at 3 to 6 months of age, mean IQ is[wvdhhr.org]


  • Prognosis The prognosis is excellent if timely treated. Most of the children achieve normal physical and mental growth. Regular follow-ups and blood thyroid hormone measurements are needed for optimum management.[lecturio.com]
  • Absence of the distal femoral ossification nucleus (“empty knee” sign) or a diameter The usefulness of the etiological diagnosis lies in the prognosis.[elsevier.es]
  • Prognosis If CH is detected early in infants and treatment begun, normal development of mental function can occur. [ 11 ] If treatment is delayed, spasticity, gait problems and dysarthria and profound mental disability may result.[patient.info]

  • Prognosis [ edit ] Most children born with congenital hypothyroidism and correctly treated with thyroxine grow and develop normally in all respects.[en.wikipedia.org]


  • Absence of the distal femoral ossification nucleus (“empty knee” sign) or a diameter The usefulness of the etiological diagnosis lies in the prognosis.[elsevier.es]
  • The association between cardiac malformations and mean T4 and TSH concentrations, etiology of CH according to radiologic findings and permanent and transient CH were studied in CH patients.[ingentaconnect.com]
  • The etiology of TD, which is the most common cause of CH, is largely unknown.[dovepress.com]
  • Hypothyroidism, usually of autoimmune etiology and only occasionally of nonautoimmune etiology, has been reported to be associated with dRTA.[thetrp.net]
  • Results: Although we could not entirely ignore the possible role of environmental and autoimmune factors in the development and function of thyroid gland, our findings strongly suggest the role of genetic factors as dominant etiologic factor in CH.[advbiores.net]

  • Epidemiology In the UK, 1 in 4,000 live births have CH. The incidence is twice as common in girls. [ 1 ] Areas with iodine deficiency associated with endemic CH are Bangladesh, China, Peru and Zaire.[patient.info]

  • However, studies have reported a change in the epidemiology, with a doubling in incidence to around 1 in 1500 live newborns. [1, 2] This is thought to be due in part to an increase in congenital hypothyroidism with thyroid gland-in-situ (GIS). [3] Lower[emedicine.medscape.com]

  • Almost all babies in New Zealand are screened, and early detection can prevent severe disability and death. Approximately 45 babies a year are identified through screening with one of the conditions.[nsu.govt.nz]
  • If tests are positive, they can take measures to prevent the disease from progressing.[medicalnewstoday.com]
