Ureaplasma urealyticum and large colony mycoplasma colonization in female children and its relationship to sexual contact, age, and race.

In order to determine if Ureaplasma urealyticum (Uu) or large colony mycoplasma (LCM) colonization was related to a history of sexual abuse, the type of sexual contact, an enlarged vaginal introitus transverse diameter (greater than 4 mm), age or race, 452 female children, ages 1-12 years, were evaluated by the Child Sexual Abuse Team at Wake Medical Center in Raleigh, NC. Thirty-six girls were deleted because of inadequate cultures. When controlled for race and age, Uu throat (T), vaginal (V), and rectal (R) colonization and LCM vaginal and rectal colonization were not related to any of the other variables listed above. The enlarged vaginal introital diameter was related to a history of sexual abuse (p less than .001). Uu and LCM vaginal colonization rates were increased in black girls as compared to white girls (p less than .05). Uu V, Uu R, LCM V, and LCM R colonization increased with age. In our study population, Uu and LCM colonization was not a useful marker of sexual contact.     

Empowering parents of pre-school children

This paper describes a project undertaken with parents from an inner city primary school in Hartlepool, England. The main objectives of the project were to increase the self esteem of the parents, to give them an understanding of the pre-school curriculum and to enable them to develop their skills, knowledge and confidence to become involved in school life and to take ownership of their own children's education. The project focused around the production of a video to show nursery life in the school and this production was used as a vehicle to encourage the fulfilment of the objectives described above. The paper concludes by describing the successful outcomes of the project. Some of the outcomes were planned for, but we were equally delighted with the unexpected ones.     

The Health Risks of Doping during the Cold War: A Comparative Analysis of the Two Sides of the Iron Curtain

This article compares East Germany's Cold War-era approach to doping to that of the USA's in terms of their respective impacts on medical risk. Although deserving of criticism on many levels, the GDR doping programme featured a number of safeguards designed to minimise medical dangers. Unlike their East German counterparts, American governmental units were not directly involved in the administration of performance-enhancing substances. The US approach to doping was not ideal in terms of medical risk, however. As a result of the country's regulatory approach to doping, the country's athletes frequently turned to black market sources for doping agents. It was also relatively common for American athletes to use performance-enhancing drugs without the benefit of medical supervision. The US approach to doping was in these ways inferior to that of East Germany's on the subject of medical risk.
