BACKGROUND: Van Wyk-Grumbach syndrome (VWGS) is a rare presentation of juvenile hypothyroidism which manifests in females as chronic autoimmune hypothyroidism, isosexual pseudoprecocious puberty, and multicystic ovaries. It uniquely presents with short stature and delayed bone age unlike other causes of precocious puberty. Kocher-Debré-Sémélaigne (KDSS) is a rare presentation of juvenile hypothyroidism manifesting as calf muscle pseudohypertrophy, delayed contraction and relaxation of reflexes, and percussion myxedema...

PURPOSE OF REVIEW: This article provides an overview of endocrine emergencies with potentially devastating neurologic manifestations that may be fatal if left untreated. Pituitary apoplexy, adrenal crisis, myxedema coma, thyroid storm, acute hypercalcemia and hypocalcemia, hyperglycemic emergencies (diabetic ketoacidosis and hyperglycemic hyperosmolar state), and acute hypoglycemia are discussed, with an emphasis on identifying the signs and symptoms as well as diagnosing and managing these clinical entities...

Myxedema crisis is a life-threatening extreme form of hypothyroidism with a high mortality rate if left untreated. Myxedema crisis is commonly seen in older patients, especially in women, and is associated with signs of hypothyroidism, hypothermia, hyponatraemia, hypercarbia, and hypoxemia. Patients might present with different organ specific symptoms. Seizures are a recognized but rare manifestation of myxedema with a very high mortality rate. Prompt diagnosis and appropriate management may improve the prognosis...

RAIONALE: Myxedema coma (MC) is extremely rare but lethal in pediatric patients with hypothyroidism leading to altered mental status and hypothermia. But there is no clinical guideline for such cases. PATIENT CONCERNS: A 6-year-old Chinese girl presented with coma and hypothermia preceded by pneumonia. Her lab results were: free thyroxin (T4) 4.18 pmol/L and thyroid-stimulating hormone (TSH) > 150 μIU/mL with extremely elevated anti-thyroid peroxidase (TPO-Ab) and anti-thyroglobulin...

Myxedema coma, caused by severe lack of thyroid hormone, is characterized by deterioration of mental status, hypothermia, hypotension, hyponatremia, and hypoventilation. We describe an 84-year-old woman who presented with renal failure and new onset severe hypothyroidism leading to challenges in the recognition of myxedema coma.

The authors report a case of pretibial myxedema (PTM) masquerading as a venous leg ulcer to alert wound care clinicians to this diagnostic possibility. Pretibial myxedema is a localized form of mucin cutaneous deposition characterized by indurated plaques most commonly on anterior legs. It is more likely to present in patients with Graves' disease, but it can be found in euthyroid patients as well. The physiopathology of PTM is complex, and there is an accumulation of highly hydrophilic glycosaminoglycans in the dermis...

The endocrinological emergency of a fully blown myxedema crisis can present as a multicolored clinical picture. This can obscure the underlying pathology and easily lead to mistakes in clinical diagnosis, work-up, and treatment. We present a case of an unconscious 39-year-old patient with a medical history of weakness, lethargy, and findings of hyponatremia, intracerebral bleeding, and massive pericardial effusion. Finally, myxedema crisis was diagnosed as underlying cause. Replacement therapy of thyroid hormone and conservative management of the intracerebral bleeding resulted in patient's survival without significant neurological impairment...

BACKGROUND: Nivolumab is an anti-programmed cell death (anti-PD-1) monoclonal antibody that is approved by Food and Drug Administration for treatment of metastatic non-small cell lung cancer, metastatic melanoma, relapsed Hodgkin lymphoma and advanced renal cell cancer. We report a rare case of myxedema crisis induced by nivolumab in a patient with metastatic squamous cell carcinoma of lung. CASE PRESENTATION: Fifty three-year old woman with metastatic squamous cell carcinoma currently on treatment with nivolumab presented with diffuse facial and tongue swelling, slurred speech, depressed mentation, fatigue and weakness...

BACKGROUND: Myxedema coma is a life-threatening and emergency presentation of hypothyroidism. However, the clinical features and outcomes of this condition have been poorly defined because of its rarity. METHODS: We conducted a retrospective observational study of patients diagnosed with myxedema coma from July 2010 through March 2013 using a national inpatient database in Japan. We investigated characteristics, comorbidities, treatments, and in-hospital mortality of patients with myxedema coma...

Myxedema psychosis is uncommon in patients with primary hypothyroidism. Most often, this disease state can be found in patients with Hashimoto thyroiditis or after total thyroidectomy. Chronic hypothyroidism can lead to an insidious onset of psychiatric symptoms in patients, such as dementia, delirium, psychosis, hallucinations, and coma. A 31-year-old man with an unremarkable medical history was brought to the psychiatric emergency department for new-onset aggression, paranoid behavior, and hallucinations for 4 days...

Hypothyroidism is a prevalent condition in the general population that is treatable with appropriately dosed thyroid hormone replacement medication. Infrequently, patients will present with myxedema coma, characterized by hypothermia, hypotension, bradycardia, and altered mental status in the setting of severe hypothyroidism. Myxedema coma has also been known to manifest in a number of unusual and dangerous forms. Here, we present the case of a woman we diagnosed with an uncharacteristic expression of myxedema coma and nonconvulsive seizure complicated by a right middle cerebral artery infarct...

Background. Pretibial myxedema (PTM) is a rare dermopathy. The morphologic features and mechanism of its evolving process are not reported in large case series. Methods. 216 cases with PTM were retrospectively reviewed to analyze demographics, history, lesional morphology and its evolving process, histopathology and immunohistochemistry, serum TRAb levels, treatment, and outcome. Results. First appearing lesions evolved into 6 variants that were correlated with serum TRAb levels. Subvariants were caused by different kinds and frequencies of local trauma...

BACKGROUND: Myxedema coma (MC), a medical emergency defined as severe hypothyroidism leading to altered mental status, is more common in older women with hypothyroidism. METHODS/RESULTS: A 7-year-old Caucasian male with chromosome 1q deletion presented with altered mental status preceded by milestone regression. His presenting labs results were: thyroid-stimulating hormone (TSH) 0.501 μIU/ml and free thyroxine (T4) <0.5 ng/dl. His morning cortisol level was 8...

Myxedema coma and thyroid storm are thyroid emergencies associated with increased mortality. Prompt recognition of these states-which represent the severe, life-threatening conditions of extremely reduced or elevated circulating thyroid hormone concentrations, respectively-is necessary to initiate treatment. Management of myxedema coma and thyroid storm requires both medical and supportive therapies and should be treated in an intensive care unit setting.

BACKGROUND: Hyaluronidases are essential for the breakdown of hyaluronate (HA) in tissues and may be used to prevent the adverse effects of HA fillers. OBJECTIVES: We explored the effect of hyaluronidase on exogenous and endogenous HA in vitro and in vivo. MATERIALS AND METHODS: HA fillers were incubated with different concentrations of hyaluronidase and visualized by electrophoresis. HA fillers were injected in the skin of hairless mice, and 4 h later hyaluronidase was injected in the papules of exogenous HA...
