title: [Untreated hyperthyroidism with severe cardiac complication in adolescence--a case study].
abstract: A 16-years old boy with poor family circumstances was admitted to hospital due to severe cardiac failure (stagnation in the pulmonary and systemic circulations, ejection fraction: 29%, pericardial fluid, atrial flatter) needing intensive care. Diagnostic tests revealed extreme hyper-function of the thyroid as the underlying cause. After stabilising the cardiac and hormonal states of the patient with medication, subtotal resection of the thyroid was carried out since the poor family circumstances did not make the provision of long-term thyreostatic pharmacotherapy feasible. Cardioversion solved the arrhythmia. The patient was discharged from hospital with stable circulation and normal thyroid functions after 2 months. The authors report the very uncommon complications of an endocrine syndrome with autoimmune origin rarely observed in childhood. They highlight the importance of early diagnosis and the immediate start of adequate therapy for good long-term outcome.
