"Healthcare providers who care for adolescents must screen for and treat sexually transmitted diseases like Chlamydia in order to decrease the risk of tubal damage and ectopic pregnancy. Smoking is a risk factor for ectopic pregnancy and teens should be encouraged to never start smoking or to quit if they already do smoke. Though ectopic pregnancy is more likely to occur in adults, teens are at risk as well, and early diagnosis allows for the possibility of conservative management. Recent findings Any teen who presents with amenorrhea, pain, or vaginal bleeding should be evaluated for a possible ectopic pregnancy. Adolescents are more likely to present with pain than adults. Transvaginal ultrasound should be performed and if an intrauterine pregnancy or ectopic pregnancy is not clearly seen, correlation with serum beta-human chorionic gonadotropin levels is done. If the beta-human chorionic gonadotropin level is above the 'discriminatory zone' of 1500 mIU and the transvaginal ultrasound does not show an intrauterine pregnancy, ectopic pregnancy should be suspected. Unruptured ectopic pregnancy may be treated with expectant management, surgical management, or medical management (methotrexate). Healthy ...
