Review Randomized Controlled Trial Comparative Study Clinical TrialOral contraceptive use among female elite athletes and age-matched controls and its relation to low back pain.
Exogenous and endogenous female sex steroids may influence the risk of low back pain. The fact that back pain is a very common symptom during pregnancy supports this theory. Back pain is also more common among female than male athletes. Oral contraceptives have been suggested to increase the risk of low back pain. ⋯ This study does not support the theory that low back pain is affected by the use of oral contraceptives. Instead, constitutional factors and mechanical stress during intense physical activity is probably more important.

To determine the effect of transfusion on hematologic recovery and mortality among severely anemic children during and after hospitalization in rural Kenya. ⋯ The use of transfusion can be improved by targeting use of blood to severely anemic children with cardiorespiratory compromise, improving immediate availability of blood, and treating severely anemic children with effective antimalarial therapy.

To determine the prevalence and risk factors associated with cervicitis caused by Chlamydia trachomatis and Neisseria gonorrhoeae in human immunodeficiency virus (HIV) type 1-seropositive and HIV-seronegative pregnant women in Bangkok, and the relation to perinatal HIV transmission. ⋯ Among pregnant women in Bangkok, C. trachomatis infection was considerably more common than N. gonorrhoeae infection and was associated with HIV infection, young age and first pregnancy (HIV-seropositive women), and multiple partners (HIV-seronegative women). Our data do not suggest an association between perinatal HIV transmission and maternal C. trachomatis or N. gonorrhoeae infection identified and treated during pregnancy. The high prevalence of C. trachomatis found using a test not readily available in Thailand emphasizes the need for improved, inexpensive ways to screen for and diagnose these sexually transmitted infections in developing countries.
