Nephrologist and Addiction Practitioner Dr. Robert Waldman testified about dermatologist Arnold Klein's medical records in Michael Jackson's treatment.  Waldman read and commented on an exhaustive day by day accounting of Klein's near daily administrations of doses of Botox, midazolam, Demerol, and Restylane.  Defense attorney, Ed Chernoff, displayed Klein's records of "Omar Arnold," one of Jackson's many aliases, spanning from March 2009 to June 2009.  During that time, it seems Klein frequently had Jackson in his office for what he labeled treatments for excessive perspiration. (Restylane is a wrinkle filler, midazolam is a benzodiazepine often used to treat anxiety, and Demerol is a powerful and addictive painkiller.)  In March 2009, Klein often started with 100-200mg of Demerol for Jackson's visits, but by May 2009, he was routinely administering 300mg of Demerol in addition to midazolam and Botox.  The Botox was injected into Jackson's groin and armpits.  Waldman said the treatments Jackson received were not painful procedures and he did not think Demerol, especially in those amounts, was a necessary accompanyment. Indeed, the Demerol was not the standard of care and the treatments themselves were unnecessary.  Click to see a screenshot of the medical record and to read more about Waldman's heated testimony.
