The Perfect Storm: A Case of Rapid-Onset Obesity With Hypoventilation, Hypothalamic, Autonomic Dysregulation, Neuroendocrine Tumor (ROHHADNET) With Heart Failure, Narcolepsy, and a Rare Location of a Pelvic Neuroendocrine Tumor.

Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) syndrome is a rare disease of concurrent respiratory dysfunction and autonomic dysregulation with endocrine abnormalities. ROHHADNET includes ROHHAD plus coexisting neuroendocrine tumors (NETs). We describe an eight-year-old boy, who originally presented at four years of age with rapid weight gain and hyperhidrosis and who developed mild obstructive sleep apnea (OSA). His clinical course was eventually complicated by hypoxic respiratory failure requiring admission to the pediatric intensive care unit (PICU). Echocardiogram at that time demonstrated dilated cardiomyopathy left ventricular ejection fraction (LVEF) of 28% at time of admission. His respiratory failure persisted despite average volume-assured pressure support (AVAPS) around the clock leading to tracheostomy placement for cardiopulmonary support. He also demonstrated autonomic instability with multiple pituitary hormone deficiencies. Computed tomography (CT) imaging of the abdomen and pelvis demonstrated a presacral soft tissue mass consistent with a tumor of neural crest origin. Daytime somnolence and confusion progressed and a low cerebrospinal fluid hypocretin level revealed a diagnosis of narcolepsy type 1.

Internal thoracic artery grafts for the entire heart at a mean of 12 years.

BACKGROUND: There is consensus today that the long-term results of bypassing the left anterior descending artery with an internal thoracic artery (ITA) graft are superior to those of a saphenous vein graft. Our hypothesis for this study was that three-vessel revascularization with only ITA grafts would also give excellent results. METHODS: Using our previously described techniques to enhance the length of ITA grafts by skeletonization and high mediastinal mobilization, we were able to perform tension-free, three-vessel revascularization using only ITA grafts in 125 (83%) of a consecutive series of 150 patients with three-vessel occlusive coronary disease. We followed 100% of these 125 exclusive ITA graft patients (average of 3.9 anastomoses per patient) to their time of death (59; 47.2%) or current living status (66; 52.8%). RESULTS: Combined intraoperative graft flows averaged 225 mL/min. Of the 125 patients in this study (average age, 63.5 years), 121 (96.8%) lived beyond 40 days. Of these 121 patients, 55 (45%) died at a mean of 7 years postoperatively and 66 (55%) are still living at a mean of 12.1 years. Of these 121 patients, 112 (93%) had angina at baseline. Of these 112, 92 (85%) were angina free at a mean of 9.1 years postoperatively. Freedom from infarction was 100% at 5 years and 97% at 10 years. Freedom from reintervention was 90% at a mean of 9.8 years. CONCLUSIONS: Use of ITA grafts for three-vessel coronary revascularization provides excellent results and is both practical and appropriate for many patients.
