A 13-year-old ballet dancer who had been dancing en pointe (on the tips of the toes) since 10 years presented to the clinic with a shortened right second toe. She had no previous history of pain or trauma.

Modern (or contemporary) dance has become increasingly popular, yet little has been reported with respect to modern dance injuries and their consequences. The purpose of this study is to define the incidence, risk factors, and management of musculoskeletal injuries in professiona lmodern dancers.

Modern dancers are a unique group of artists, performing a diverse repertoire in dance companies of various sizes. In this study, 184 professional modern dancers in the United States (males N=49, females N=135), including members of large and small companies as well as freelance dancers, were surveyed regarding their demographics and training characteristics

Talar stress injury was diagnosed in a 16-year-old ballerina who frequently danced en pointe, a position in which the subtalar joint is locked with the heel and forefoot in varus position.

Concussions are frequent injuries in athletes participating in contact sports. Many different tests are used to evaluate players suspected of sustaining a concussion, and to help determine when they are safe to return to play. The SAC test is the most frequently used on-field assessment. A new computerized neuropsychological test battery, ImPACT, has been adopted by the NFL and many collegiate football teams. Validity and reliability studies have been performed for injured vs baseline scores. The purpose of our study was to determine if there is a difference in SAC and ImPACT scores when uninjured football players, who were involved in repetitive contact activity, are tested pre-season, mid-season, and post-season.

Although the antidiarrheal loperamide is a potent opiate, it does not produce opioid central nervous system effects at usual doses in patients. On the basis of in vitro studies demonstrating that loperamide is a substrate for the adenosine triphosphate-dependent efflux membrane transporter P-glycoprotein, we postulated that inhibition of P-glycoprotein with quinidine would increase entry of loperamide into the central nervous system with resultant respiratory depression.

Intraoperative rhabdomyolysis with resultant acute renal failure is a rare complication seen, most commonly, with urologic surgical procedures. Since the early 1990s, the refinement of laparoscopic techniques has permitted their application more broadly. Among the procedures to benefit from these less invasive surgical methods has been radical nephrectomy. In general, this has resulted in less postoperative pain and shorter convalescence.
