Kidney stone product marketer defies FDA warning. An FDA warning to the primary marketer of Uriflow appears to have been ignored. In November 2006, the agency warned Bioneutrix Healthcare to stop claiming that their proprietary herbal mixture can prevent, dissolve, and "painlessly flush out" kidney stones and that there have been "over 80,000 successful cases." However, the challenged claims still appear online. The company also appears to be using Better Business Bureau and TRUSTe logos without authorization and may be touting an endorsement from a nonexistent urologist. [Barrett S. Dubious claims for Uriflow. Quackwatch, April 4, 2007]


USANA embroiled in controversy. USANA Health Sciences, Inc. and three of its top officers are facing class-action lawsuits by shareholders who allege:

In March, USANA reported that the U.S. Securities and Exchange Commission had begun an informal inquiry. The investigation appears to have been generated by a lengthy report issued by the Fraud Discovery Institute. USANA responded to that report by suing its author for libel.

Adverse events associated with chiropractic care of children. A systematic review has identified 34 cases in which spinal manipulation in children was associated with adverse events. [Vohra S. Adverse events associated with pediatric spinal manipulation: A systematic review. Pediatrics 119(1) January 2007, pp. e275-e283] Fourteen of the cases involved "direct" events in which the treatment was followed by death, serious injury, symptoms requiring medical attention, or soreness. The rest involved "indirect" events in which appropriate diagnosis was delayed and/or inappropriate manipulation was done for serious medical conditions such as meningitis. The reviewers commented that despite the fact that spinal manipulation is widely used on children, pediatric safety data are virtually nonexistent. This type of review cannot determine how often adverse events occur. That would require a prospective study with active surveillance. The article did not consider harmful aspects of chiropractic care that are far more common than the reported events. These include (a) decreased use of immunization due to misinformation given to parents, (b) psychologic harm related to unnecessary treatment, (c) psychologic harm caused by exposure to false chiropractic beliefs about "subluxations," and (d) financial harm due to unnecessary treatment.
