“…Methadone has been used in children for various pain entities, including acute procedure-related pain for burn care (Williams, Sarginson & Ratcliffe, 1998), other types of non-cancer pain in hospitalized children (Shir, Shenkman, Shavelson, Davidson, & Rosen, 1998), and for severe cancer-related pain (Sabatowski, Kasper, & Radbruch, 2002), chronic cancer-related pain (Martinson et al, 1982; Rowbotham et al, 2003), and cancer-related end of life care (Sirkia, Hovi, Pouttu, & Saarinen-Pihkala, 1998). In adults, methadone is also used for neuropathic pain entities: phantom limb pain (Bergmans, Snijdelaar, Katz, & Crul, 2002), diabetic neuropathy (Hays, Reid, Doran, & Geary, 2005), intractable neuropathic non-cancer pain (Altier, Dion, Boulanger, & Choiniere, 2005; Moulin, Palma, Watling, & Schulz, 2005), neuropathic pain related to burns (Altier, Dion, Boulanger, & Choiniere, 2001), and cancer-related neuropathic pain (Makin & Ellershaw, 1998). …”
