A 51-year old female, treated for hyperthyroidism with methimazole, developed agranulocytosis in the third month of therapy. After discontinuing the drug, a broad spectrum antibiotic regimen plus recombinant human granulocyte colony-stimulating factor (G-CSF) were started. Her granulocyte count returned to normal with the 4(°) dose of G-CSF. We think that in patients with methimazole-induced agranulocytosis, G-CSF may reduce the risk and severity of infection and in some cases should be accepted as a part of the standard therapy.

Introduction: Methimazole is an antithyroid drug known to cause hematological toxicity, including agranulocytosis and, very rarely, pancytopenia. We herein present a case of a patient with Graves' Disease (GD) who developed methimazole-induced pancytopenia.
Case Report: A 53-year-old Peruvian woman with GD, initially treated with methimazole 20 mg BID, experienced odynophagia, fever, and malaise after 37 days of treatment.

Amiodarone is a class III anti-arrhythmic drug found to be effective in treating multiple life-threatening arrhythmias, including paroxysmal atrial fibrillation. Despite its effectiveness, amiodarone has been found to result in thyroid dysfunction. Amiodarone-induced thyrotoxicosis (AIT) is classified as type 1, which often develops in those with autoimmune hyperthyroid conditions, or type 2, which occurs because of destructive thyroiditis in an apparently normal thyroid.

Introduction: Thyroid storm is a rare but potentially life-threatening metabolic disorder that presents unique management challenges in the emergency department. Thionamides are commonly used as monotherapy for first-line treatment of hyperthyroidism.
Case Report: In this case, a 26-year-old male presented to the emergency department with sore throat, fever, and diarrhea.
Introduction: Agranulocytosis is a rare, but serious complication of methimazole (MMI) use for Graves' disease (GD). Treatment requires discontinuation of MMI, and the use of propylthiouracil (PTU) is also contraindicated. Few reports exist about the optimal alternative treatment regimens for the management of thyrotoxicosis in these medically complex patients in the pediatric population.

is closely related to carbimazole/methimazole-induced agranulocytosis. This study aimed to develop and validate a rapid and economical method for genotyping. A single-tube multiplex real-time PCR detection system comprising amplification refractory mutation system primers and TaqMan probes was established for genotyping.
