             (ADHD), with the exception of hormone replacement therapies (thyroxine,
             hydrocortisone, desmopressin (DDAVP))

         13. Children requiring glucocorticoid therapy (e.g. asthma) who are taking a dose of
             greater than 400 µg/d of inhaled budesonide or equivalents for longer than 1 month
             during a calendar year.

         14. Major medical conditions and/or presence of contraindication to r-hGH treatment.

         15. Known or suspected HIV-positive patient, or patient with advanced diseases such as
             AIDS or tuberculosis.
