Presentation
The second infant presented with thyroid storm and the third infant present with neonatal hyperthyroidism, and both required treatment with antithyroid drugs. [ncbi.nlm.nih.gov]
In our three cases, we report various clinical presentations, from fetal death to neonatal hyperthyroidism with different grade of severity. [jmedicalcasereports.biomedcentral.com]
Entire Body System
- Fever
Diagnosis is based on a combination of signs and symptoms: fever, tachycardia out of proportion to the fever, altered mental status (nervousness, restlessness, confusion, seizures), vomiting, diarrhea, and cardiac arrhythmia. [aafp.org]
In subacute thyroiditis these manifestations are present but less severe and may have been preceded by a viral illness; fever may last for several weeks. [merckmanuals.com]
Thyroid storm is characterized by exaggerated symptoms of hyperthyroidism, such as a very fast heart rate, high fever, diarrhea, agitation, delirium, and/or decreased consciousness. [verywell.com]
Thyroid storm, a serious form of hyperthyroidism, may show up as sudden and acute symptoms, some of which mimic typical hyperthyroidism, as well as the addition of fever, substantial weakness, extreme restlessness, confusion, emotional swings or psychosis [healthofchildren.com]
Patients must be warned to seek urgent medical review and have blood tests, should they develop fever, mouth ulcers and sore throat. Carbimazole may be stopped when remission is achieved (usually after 18–24 months of starting treatment). [dermnetnz.org]
Gastrointestinal
- Failure to Thrive
Clinical features of neonatal hypothyroidism Age Clinical signs/features Birth Post term, large for dates, transient temperature instability, large posterior fontanelle, goitre Early signs Hypotonia, poor feeding, failure to thrive, prolonged jaundice [www2.health.vic.gov.au]
They can include: Low birth weight Small or abnormally shaped head Poor weight gain (failure to thrive) Enlarged liver and spleen Swelling of the front of the neck due to large thyroid (goiter) Fast heartbeat, which can lead to heart failure Warm, moist [childrensnational.org]
Other early findings are failure to thrive, vomiting, and diarrhea. Affected infants almost always recover within 6 mo; the course is rarely longer. [merckmanuals.com]
Cardiovascular
- Hypertension
Beta-blockers, such as atenolol or propranolol, may be used to control hypertension and tachycardia. [merckmanuals.com]
The pregnancy was complicated by pregnancy-induced hypertension and vaginal bleeding. The infant required nasal-CPAP for 3 days, was transitioned to room air, and discharged on day 10 of life. [acgcasereports.gi.org]
It is an important condition to treat adequately as if uncontrolled it is associated with important health risks both for the mother (a five-fold increase in pregnancy-induced hypertension, and very rarely the occurrence of a thyroid storm or heart failure [icid.salisbury.nhs.uk]

The many signs and symptoms of hyperthyroidism include tremors, nervousness, insomnia, excessive sweating, heat intolerance, tachycardia, hypertension, and goiter. Graves' disease is responsible for 95 percent of hyperthyroidism cases in pregnancy. [aafp.org]
Face, Head & Neck
- Neck Mass
Abstract On the rare occasion when neonatal goiter is the cause of airway compromise, it typically presents with a palpable neck mass. [ncbi.nlm.nih.gov]
Neurologic
- Agitated Delirium
Thyroid storm is characterized by exaggerated symptoms of hyperthyroidism, such as a very fast heart rate, high fever, diarrhea, agitation, delirium, and/or decreased consciousness. [verywell.com]
Urogenital
- Vaginal Bleeding
Case Report A 2.126-kg male infant born via vaginal delivery at 35.5 weeks gestational age to a G1P1 mother developed jaundice. The pregnancy was complicated by pregnancy-induced hypertension and vaginal bleeding. [acgcasereports.gi.org]
Workup
Laboratory workup showed a thyroid-stimulating hormone (TSH) of 0.009 uIU/mL and free T4 (FT4) of 1.4 ng/dL. TSAbs were negative. The infant was progressing as expected until DOL 7 when she developed tachycardia with a heart rate in 220 s. [jcnonweb.com]
(See Workup, Treatment, and Medications.) Although Perry was first to report hyperthyroidism in English, the classic description, in 1835, by Graves became most widely accepted. Europeans often prefer to recognize the description by Basedow. [emedicine.medscape.com]

Serum T4 also decreased after ipodate administration to 69% and 41% of the pretreatment value after 72 h and 7 days of treatment, respectively; values thereafter during treatment ranged from 19-22 micrograms/dl. [ncbi.nlm.nih.gov]
Prognosis
Early diagnosis and treatment are key objectives for an optimal prognosis and the well-being of the child. This review focuses on the management of these patients during the fetal and neonatal periods. [ncbi.nlm.nih.gov]
Immediate treatment is essential for a good prognosis, prenatal treatment improves foetal and neonatal development. [endocrine-abstracts.org]
Prognosis Hyperthyroidism is generally treatable and carries a good prognosis. Most patients lead normal lives with proper treatment. Thyroid storm, however, can be life-threatening and can lead to heart, liver, or kidney failure. [healthofchildren.com]
Therefore, the prognosis of the disorder greatly depends on the form of therapy chosen. [emedicine.medscape.com]
Etiology
Introduction Neonatal cholestasis can be due to a variety of etiologies, including anatomic abnormalities, infections, and metabolic diseases. [acgcasereports.gi.org]

Epidemiology and aetiology In Europe, thyrotoxicosis affects around 1 in 2,000 people annually. [ 1 ] Graves' disease is the most common cause of thyrotoxicosis, accounting for around 75% of cases. [patient.info]
Epidemiology Occurrence in the United States The prevalence of Graves disease in childhood in the United States has not been quantitated. An incidence of 0.2-0.4% has been speculated but is probably an overestimation. [emedicine.medscape.com]
