Unplanned pregnancy is a major public health problem in the United States. Emergency contraception has the potential to significantly decrease the incidence. The Yuzpe regimen is highly effective but woefully underutilized. Mechanisms of action of hormonal emergency contraception will be discussed as well as appropriate indications for use, patient counseling issues, and future methods.

Chlamydia trachomatis is a major human genital pathogen implicated as a leading cause of involuntary infertility in women. To assess the prevalence of results positive for C trachomatis by a direct immunofluorescent test in a family planning population, mass screening of all patients attending five urban family planning clinics was conducted for a two-month period. The objectives of this study were to assess the prevalence of positive C trachomatis test results in this population and to evaluate the commonly accepted demographic/behavioral risk factors reported in previous studies. A total of 2,761 subjects were tested using the MicroTrak collection kit. The subjects ranged in age from 12 to 69 years. The overall rate of positive test results was 10.5%. Significant associations between C trachomatis test results and the following variables were observed: race/ethnicity, age, marital status, existence of multiple partners and positive gonorrhea tests. Chlamydial infection was not significantly associated with income, pregnancy, current contraceptive method or age at first intercourse. While the results of the study indicated both agreement and disagreement with other clinical investigations, the fact that 10.5% of a largely asymptomatic population exhibited chlamydial infection has major implications for the management of women's reproductive health care.

Endoscopically placed inlying ureteral stents have proved useful in the conservative management of patients with ureteral obstruction, urinary fistula, and malignancy and have obviated the need for operative intervention. In high-risk symptomatic patients with widespread malignancy, internal urinary diversion offers the opportunity for an improved quality of life without the surgical risk or potential morbidity of supravesical diversion. Potential candidates for this simple, safe, and effective technique include: those with postsurgical obstruction and/or fistula, retroperitoneal fibrosis, metastatic carcinoma, congenital ureteropelvic junction obstruction, as well as those with reversible obstruction from lymphoma and carcinoma of the prostate who are undergoing radiotherapy and/or chemotherapy. The focus of this report is on the technique we have found successful in providing us with stents that fit our individual patients. Readily available fabricated graduated ureteral catheter can be cut and shaped to particular measurements unlike prefabricated catheters. Minimal preparation time is demanded, and there is no need for extensive stocking of various catheter sizes.
