title: [Vomiting as main symptom: unusual presentation of a hyperthyroidism in a 12-year-old boy].
abstract: A twelve year old boy presented with a sudden onset of recurrent nausea and vomiting. During the past six weeks he had a weight loss of 13 kg. While he was in the hospital, persistent tachycardia and a slightly elevated blood pressure were noted. The gastroenterologic, cardiologic and neuropediatric examinations were normal. To exclude the differential diagnosis of hyperthyroidism, thyroid hormones were checked. They showed clearly elevated levels of tri-iodothyronine and thyroxine, while thyrotropin was suppressed. The boy did not have a goiter. Under thyrostatic therapy his clinical condition improved quickly. Among our 20 patients with hyperthyroidism he was the only one whose main symptom was severe vomiting.
