The congenital long-QT syndrome (LQTS) is characterized by recurrent syncope, prolonged QT intervals, QT interval lability, polymorphic ventricular tachycardia, and sudden death. We report a case of congenital long QT syndrome in a 28-day-old male infant who presented with syncope, bradycardia with 2: 1 pseudo-atrioventricular block and a markedly prolonged QT inteval. One episode occured after crying and degenerated into ventricular fibrillation and terminated after cardioversion. A VVI type cardiac pacemaker was implanted. Subsequently, the infant's heart rate was over 110/min and 2: 1 AV block and any other arrhythmia were absent. The infant recovered from the accompanied pneumonia and sepsis and was discharged 47 days after adrnission. However, 13 days after discharge, the infant returned to our hospital ER with syncope. Ventricular fibrillation ceased after cardioversion. Despite medication with propranolol, ventricular tachycardia persisted. The infant expired the day after he was discharged against medical advice.

Adult intussusception represents 1% of patients with bowel obstruction and 5% of all intussusception. It presents with a variety of acute, intermittent and chronic symptoms, thus making its preoperative diagnosis is difficult. Overall, colonic intussusception in adults is most often related to a primary carcinoma and benign smooth muscle tumors of the gastrointestinal tract are uncommon. We experienced a case of adult intussusception of the colon caused by leiomyoma. The 18-year old man was suffered from intermittent, colicky left lower quadrant pain and bloody diarrhea. Physical examination revealed a mass in the left lower abdomen. An abdominal CT scan revealed a "target mass" in the distal colon. The patient was treated with segmental resection of the descending colon and anastomosis. Pathology revealed a benign leiomyoma of the distal colon as the leading point of the colo-colic intussusception. His postoperative course was uneventful and did well.
