MSNBC's Rita Cosby reports that Anna Nicole may have had recent breast surgery to repair one of her implants.
Cosby also reports the former Playmate had also been prescribed over 10 different types of pain medication, and may have been taking excessive amounts because she developed a tolerance to the effects.
In addition, Cosby's sources tell her that Anna Nicole was found by a member of her staff -- unresponsive and nude in her bed, with a sheet pulled over her face.
Death from cosmetic plastic surgeries occurs in one out of 57,000 cases, per the American Society of Plastic Surgeons. Two million plastic surgeries were performed in the United States in 2005.
Adverse reactions to surgery could become serious; there are numerous documented cases of seizures, heart attacks and high fevers leading to death. Recent published research shows that inflammation caused by common respiratory and urinary tract infections like bronchitis, pneumonia and cystitis, may contribute to in increased risk of heart attack and stroke, and the greatest risk is in the earliest stages of infection.
If Anna did have a recent cosmetic procedure, and she exhibited "flu like symptoms" over the last few days, it's quite possible that the star died of a massive infection, perhaps complicated by an accidental overdose of prescription drugs.
