A case of fatal myxedema coma with electrocardiogram Osborne J-wave in a patient initially diagnosed with hypothyroidism.

Endocr J 2022 Apr 9. Epub 2022 Apr 9.

Department of Internal Medicine, Uwajima City Hospital, Ehime 798-8510, Japan.

Myxedema coma is a life-threatening endocrine emergency with a high mortality rate resulting from severe insufficiency of thyroid hormones. Intravenous levothyroxine replacement is considered the standard therapy for myxedema coma in many countries. In Japan, however, although there are diagnostic criteria highly suggestive or diagnostic for myxedema coma, no management strategy has been established, despite the availability of levothyroxine.

A Rare Case of Hypoparathyroidism and Myxedema Coma in a Patient With Diamond-Blackfan Anemia.

Cureus 2021 Nov 27;13(11):e19941. Epub 2021 Nov 27.

Internal Medicine, Northwell Health, New York, USA.

Diamond-Blackfan anemia (DBA) is a rare genetic condition that presents due to bone marrow failure caused by a dysfunction in ribosomal biogenesis and function. The patients would often require chronic transfusions as treatment, which puts them at high risk for the development of secondary hemochromatosis. This secondary hemochromatosis results in endocrinopathies due to iron deposition into the endocrine glands. Read More

The Abnormal Sinus Rhythm: Myxedema Coma Complicated by Subacute Cardiac Tamponade.

Cureus 2021 Nov 13;13(11):e19535. Epub 2021 Nov 13.

Cardiology, Veterans Affairs New York Harbor Healthcare System, Brooklyn Campus, Brooklyn, USA.

Subacute cardiac tamponade (SCT) is a potentially life-threatening condition that requires immediate medical attention. Combining careful history taking, focused physical exam, and the use of point of care ultrasound (POCUS) for early diagnosis with aggressive management can minimize potential complications. In patients with severe hypothyroidism and myxedema coma, clinical signs of cardiac tamponade may be masked and lead to delayed diagnosis. Read More

Myxedema Coma: Case Report and Literature Review.

Cureus 2021 May 27;13(5):e15277. Epub 2021 May 27.

Internal Medicine, Rutgers-New Jersey Medical School/Trinitas Regional Medical Center, Elizabeth, USA.

Myxedema coma is a life-threatening manifestation of hypothyroidism associated with altered mental status, hypothermia, and symptoms related to the slowing of other organ systems. It can occur as a culmination of severe, longstanding hypothyroidism or be precipitated by acute stressors such as infection, myocardial infarction, cold exposure, and surgery in patients with poorly controlled hypothyroidism. Given the high mortality rate and acuity with which the disease presents, treatment with thyroid hormone replacement should be initiated upon suspicion of the disease even prior to obtaining laboratory confirmation.

Hypothyroidism: Diagnosis and Treatment.

Am Fam Physician 2021 05;103(10):605-613

University of Pittsburgh Medical Center St. Margaret Family Medicine Residency Program, Pittsburgh, PA, USA.

Clinical hypothyroidism affects one in 300 people in the United States, with a higher prevalence among female and older patients. Symptoms range from minimal to life-threatening (myxedema coma); more common symptoms include cold intolerance, fatigue, weight gain, dry skin, constipation, and voice changes. The signs and symptoms that suggest thyroid dysfunction are nonspecific and nondiagnostic, especially early in disease presentation; therefore, a diagnosis is based on blood levels of thyroid-stimulating hormone and free thyroxine.
