    General Discussion
    Rapid-onset obesity, hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) is a rare disorder first described in 1965. Since that time fewer than 50 children have been described in the literature with this disorder. These patients have a somewhat variable presentation, but they typically show the following constellation of symptoms: increased hunger (hyperphagia), obesity, impaired control of breathing (hypoventilation), poor temperature control, water imbalance, decreased pain perception, behavioral disorders, strabismus, abnormal pupil responses, elevated prolactin levels, altered onset of puberty, and tumors of neural crest origin.

    Though these children can often be supported with mask ventilation at night only, a subset will require 24 hr/day ventilation via an opening in the throat (tracheostomy) into which a small tube (cannula) is inserted, through which mechanical ventilation can be delivered.
