A case report of surgical treatment of amiodarone-induced thyrotoxicosis in a patient with multiple organ failure

Amiodarone is a drug used in the treatment of life-threatening arrhythmias, which can lead to the development of amiodarone-induced thyrotoxicosis. In most cases this pathology can be treated by conservative methods; surgical treatment is resorted to in cases of thyrotoxicosis refractory to medical treatment. This case report describes surgical treatment of a patient with amiodarone-induced thyrotoxicosis, progressive heart failure, neurological pathology, bilateral pneumonia, functioning tracheostomy, systemic infectious process, multiple organ dysfunction syndrome, who was treated in the intensive care unit. Due to the lack of response to therapy with antithyroid drugs (thiamazole, lithium preparations and pulse therapy with prednisolone) and a progressive deterioration of the condition in a short period of time, according to vital indicators, the patient underwent thyroidectomy. In the postoperative period, there was a decrease in the occurrence of chronic heart failure symptoms. Medical control of cardiac arrhythmias was achieved. Surgical stage proceeded without complications in the period of 30-days. The patient was discharged for outpatient rehabilitation treatment

Stable Delay of Microstrip Line with Side Grounded Conductors

Characteristics of transmission lines are addressed. Wave impedance and per-unit-length delay of the microstrip structure with grounded side conductors on three layers are calculated under different parameters of the structure. A line which provides the desired value of wave impedance and constant per-unit-length delay, at the expense of correction of the gaps on different layers, is proposed
