[Multimodal anesthesia in a patient with Graves' disease and thyrotoxicosis: A case report]. / Anestesia multimodal en paciente con enfermedad de Graves y tirotoxicosis: reporte de caso.

Background: Hyperthyroidism is the increase in the synthesis and secretion of thyroid hormones. It is rare but serious in children and constitutes approximately 5% of all cases; 15% manifests before 10 years of age. The peak of presentation and the majority of cases (80%) are diagnosed around 10-15 years of age. Adolescence is usually the stage with the highest incidence and it is more frequent in women (5:1). Acute thyrotoxic crisis or thyroid storm is rare and only occurs in a poorly controlled hyperthyroid patient or in a hyperthyroid patient undergoing emergency surgery. It is manifested by fever, extreme tachycardia, tachyarrhythmia with atrial fibrillation, vomiting, diarrhea, agitation and mental confusion. Clinical case: 17-year-old adolescent with Graves' disease with uncontrolled clinical manifestations that did not respond to medical treatment and was scheduled for radical thyroidectomy. 35 points were obtained on the Burch and Wartofsky Scale. It was managed with general anesthesia, reducing stimuli for airway and regional control to reduce surgical stimuli. Adjuvant medications such as magnesium sulfate for intraoperative stability were used. Conclusion: Multimodal anesthesia managed to avoid thyroid storm, postoperative pain, as well as other complications.

Introducción: el hipertiroidismo es el incremento en la síntesis y secreción de hormonas tiroideas. Es raro pero grave en la edad pediátrica y constituye aproximadamente el 5% de todos los casos; el 15% se presenta antes de los 10 años. El pico de presentación y la mayoría de los casos (80%) se diagnostican hacia los 10-15 años. La adolescencia es la etapa de mayor incidencia y más frecuente en mujeres (5:1). La crisis tirotóxica aguda o tormenta tiroidea es rara y solo se presenta en un hipertiroideo mal controlado o en un paciente hipertiroideo intervenido de urgencia. Se manifiesta con fiebre, taquicardia extrema, taquiarritmia con fibrilación auricular, vómito, diarrea, agitación y confusión mental. Caso clínico: adolescente de 17 años con enfermedad de Graves con manifestaciones clínicas descontroladas, la cual no respondió a tratamiento médico y se programó para tiroidectomia radical. Se obtuvieron 35 puntos en la Escala de Burch y Wartofsky. Se manejó con anestesia general y fueron disminuyendo los estímulos para control de vía aérea y regional a fin de disminuir los estímulos quirúrgicos. Se usaron medicamentos adyuvantes como sulfato de magnesio para la estabilidad transoperatoria. Conclusión: la anestesia multimodal logró evitar la tormenta tiroidea, el dolor postoperatorio, así como otras complicaciones.

Low-dose oral propranolol for treatment of thyrotoxic periodic paralysis with hypokalaemia in the emergency department: A case report.

WHAT IS KNOWN AND OBJECTIVE: Thyrotoxic periodic paralysis (TPP) with hypokalaemia is a rare acute phenomenon. Reports of the use of high-dose non-selective ß-blockers describe symptom resolution, but often administration does not occur promptly enough in the treatment course and patients may experience overcorrection and hyperkalaemia. CASE DESCRIPTION: A 37-year-old Hispanic male developed TPP. Patient was successfully treated with low-dose oral propranolol and potassium supplementation with no overcorrection. WHAT IS NEW AND CONCLUSION: Delay in the administration of non-selective ß-blockers may lead to overcorrection of potassium with exogenous supplementation. Low-dose propranolol administered in the Emergency Department was successful in preventing overcorrection of potassium.

Thyroid storm caused by a chinese herb contaminated with thyroid hormones.

BACKGROUND: We report a case of thyroid storm caused by consuming a Chinese herb contaminated with thyroid hormones. CASE REPORT: A 70-year-old man presented to an emergency department after 2 days of nausea, vomiting, and weakness. Three days previously, he had started taking Cordyceps powder and "Flower Man Sang Hung" as recommended by his Chinese physician. Following admission, the patient deteriorated and was eventually diagnosed with thyroid storm complicated by rapid atrial fibrillation requiring cardioversion, intubation, and intensive care admission. The analysis of the Chinese herb "Flower Man Sang Hung" was positive for levothyroxine. The patient was extubated 11 days after admission and discharged to a rehabilitation centre after 17 days of hospitalization. The Chinese medicine physician was informed of the events. CONCLUSIONS: Herbal products can be the source of illness, medication interactions, and contamination. Awareness should be raised among Chinese medicine physicians, allopathic physicians, and their patients. Clinicians should also have a low threshold of suspicion to seek laboratory analysis of suspect substances when the cause of the clinical presentation is unclear.

Thyroid storm--a dramatic exacerbation of existing hyperthyroidism of sudden onset associated with hyperthermia, tachycardia and CNS symptomatology--remains a life-threatening disease. On account of an overlapping of the symptoms of precipitating conditions, and complications, e.g. thromboembolism, the clinical diagnosis is not easy, and is often established "too late'. Since an additional role is often played by exposure to iodine, treatment is also rendered more difficult, for antithyroid drugs inhibit only de novo synthesis, but not the secretion of stored thyroxin. Treatment requires the use of thyroid-specific and numerous adjuvant measures, and the patient must be admitted to an intensive care unit with relevant experience.

[Thyrotoxic crisis after exposure to iodine. A case with fatal outcome]. / Thyreotoxische Krise nach Jodexposition. Ein Fall mit letalem Ausgang.

A 78-year-old woman is presented with a multinodular toxic goiter and euthyroidism under continuous low-dose treatment with antithyroid drugs. A period of hyperthyroidism had been documented 3 years previously. In the preoperative management, prior to resection of a benign ovarian tumour, an intravenous urogram was performed. Perchlorate was given for thyroid protection. One day after surgery the clinical signs of thyroid storm were observed. Immediately, high-dose antithyroid drug therapy was started. Nevertheless, the patient died of acute cardiovascular failure 3 days later. This case report focuses on the risk of thyroid storm following iodine excess in the presence of relevant functional thyroid autonomy without adequate thyroid protection.

Acute thyrotoxicosis following the ingestion of massive doses of thyroid hormone may pose diagnostic problems when the intoxication is clandestine, and may endanger life. The authors report here the case of a previously euthyroid young woman. The outcome was favourable, though assisted ventilation was required for a number of days. The particular features of this case (relatively low blood thyroxinelevels, anaemia and thrombocytopaenia following regression of the thyrotoxicosis, presence of parotid swelling) are discussed in the context of data from the literature.
