Creatine and other supplements.

Ergogenic dietary supplement use is highly prevalent among adolescent and collegiate athletes, and use is increasing. To make appropriate recommendations for or against use by individual athletes, physicians who work with adolescent athletes should be knowledgeable about the most commonly used supplements and be able to access high-quality information about others. This article first discusses the legal and regulatory environment of dietary supplements. Several of the most commonly used supplements are then discussed in detail, including creatine, beta-hydroxy-beta-methylbutyrate, protein, amino acids, stimulants, alkalotic agents, glycerol, vitamins, and minerals. Finally, the "Gateway Theory" as it may relate to adolescent supplement and other drug use is discussed.

MDMA ('ecstasy') and other 'club drugs'. The new epidemic.

Unfortunately, perceptions that the club drugs can be safe endure. Some groups, such as the Multidisciplinary Association for Psychedelic Study, continue to lobby for the legalization of MDMA for research purposes [76]. DanceSafe is an organization that seeks to educate the "nonaddicted" user to decrease the risks [82]. The DanceSafe Web site offers tips on the safe use of MDMA, such as attention to hydration status and ambient temperature. It also offers free testing of tablets submitted by mail and sells home testing kits to determine the content of pills sold as "ecstasy." Although much remains unknown about the long-term consequences of MDMA and the club drugs, there are clearly enough short-term dangers to prompt more aggressive education and surveillance for its use. Scare tactics and exaggerations often are ignored [53], while Web sites full of anecdotal or incomplete information may lead the unaware user to increased use [113]. Organizations such as DanceSafe imply that proper education decreases addiction and that only uneducated users or addicts suffer the life-altering consequences of drug use. The fallacy in the mission of educating "nonaddicted" users is evident. Peer-based education, with a focus on both he short-term dangers and long-term consequences, may be a more effective approach [9]. Both new and established drugs of abuse continue to plague teens and young adults. Pediatric, family practice, and Med-Peds physicians, and pediatric pharmacologists need to remain vigilant about patterns and trends of drug abuse. MDMA and the other "club drugs" are not benign. Their effects target the brain, alter neurochemistry, and possibly cause irreversible structural damage. What may seem like a harmless drug in a weekend dance club has the potential for major public health problems in years to come [109]. Effective education and timely intervention may prevent these addictive drugs from becoming a way of life, a lifestyle that may have a literal "dead end."

Phantom limb pain--a complication of lower extremity wound management.

Amputation is one treatment option for patients with critical limb ischemia, diabetic foot wounds, and occasionally, even venous leg ulcers. Amputation of the whole limb or part of it or the digits can cause complications including pain. Post-amputation pain, and especially phantom limb pain (PLP), is a poorly understood phenomenon. Effective management of established pain is a major challenge. This review is for wound workers who are a multiprofessional group. Any amputated limb, appendage, or viscera can be affected by PLP,though the focus of this article will be the treatment of PLP following limb loss. The pathophysiology is still not fully understood. The size of the problem of PLP, possible underlying physiological mechanisms, and potential preventative measures are presented in this article.

The nonmedical use of prescription drugs by adolescents.

The abuse of prescription drugs such as opioids, stimulants, tranquilizers, and sleeping pills is the fastest-growing class of drugs being abused by adolescents. Among this class of drugs, prescription opioids are being abused the most, although the abuse of prescription stimulants has been studied the most. There is a paucity of information on the nonmedical use of tranquilizers and sleeping pills. In this article we will discuss the specific prescription drugs that are most commonly abused by adolescents and how physicians need to be cautious when prescribing these drugs. The issue of screening for the abuse of these drugs will be addressed, as will the importance of parents' monitoring the use of these drugs by their own children.
