do Ouvidor 166 (endereços que provavelmente não existem mais) o livro do autor Ramiz Galvão denominado Vocabulário Etymologico, Orthographico e Prosodico das Palavras Portuguezas derivadas da língua grega (grafia da época). Na página 574 (respeitando a grafia original) encontramos: THYREÓIDE, s.f.(anat.) cartilagem situada na parte antero-superior da laringe, semelhante a escudo. Nos livros e lexicos antigos davam thyroide; mas já Littré advertiu com acêrto que isso se deva corrigir. Deriv.: thyreóideo (adj), thyreoidite (s.f.), thyreoidismo (s.m.), thyreoidina (s.f.) Obs.: possuo uma cópia do livro gentilmente cedido pelo Prof. Dr. Roberto Alvarenga, eminente médico patologista ao qual agradeço. Atenciosamente, do colega endocrinologista de Belo Horizonte,
Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare hyperthyroidism complication much more frequent in Asians and Caucasians. We present 3 cases of THPP occurring in Brazilian male patients with 28 years old (y) (Case 1), 29 y (Case 2) and 60 y (Case 3), respectively. They were admitted following an episode of flacid paralysis of extremities. Whereas case 1 reported recurring episodes of paralysis crises, cases 2 and 3 reported only one episode. Signs and symptoms of thyrotoxicosis, such as weigh loss, diaphoresis, extremities tremor, palpitation and mild diffuse goiter were present in the first case; while the second case only presented ophthalmopathy and the third patient referred that 2 years before his admission he presented an episode of cardiac arrhythmia but did not have thyroid function evaluation at that time. Their laboratory findings were hypokalemia, low TSH and raised free T4. They were treated with intravenous potassium, oral propranolol and tiamazol with remission of the symptoms. We report these cases to emphasize the importance of recognizing hyperthyroid periodic paralyses to avoid missing a treatable and curable condition.
