ABSTRACT
OBJECTIVE: To review and compare the treatments for ectopic pregnancy in a university setting serving an indigent population. STUDY DESIGN: Charts assigned an ICD-9 code for ectopic pregnancy from January 1, 1993, through December 31, 1998, were reviewed for presenting symptoms, hCG levels, ultrasound findings, treatment modality and need for subsequent treatment. RESULTS: Of 401 patients treated for ectopic pregnancy, 7 were managed expectantly. One hundred nineteen (30%) patients received methotrexate. Seventy percent (83/119) of these ectopic pregnancies resolved with a single dose and an additional 11 after a second dose, for a 79% overall success rate. Twenty-five patients (21%) failed methotrexate therapy and required surgical treatment, and 11 (9%) pregnancies were ruptured. Primary treatment was surgical in 275 (69%) patients: 172 (63%) underwent laparoscopy and 103 (37%) laparotomy. Primary laparoscopic treatment was successful in 90%. Success rates were significantly lower for medical therapy as compared to laparoscopic treatment (79% vs. 90%, odds ratio 2.2, 95% confidence interval 1.1, 4.3; P = .02). No discriminating predictors of successful treatment with methotrexate were identified. CONCLUSION: The success rate of methotrexate therapy for ectopic pregnancy was lower than that of surgical management in a university setting serving an indigent population.

Amniotic fluid from 135 pregnancies was assayed for human chorionic gonadotropin (hCG) and its free alpha (ahCG) and free beta (bhCG) subunits. Forty-six chromosomally abnormal pregnancies between 14 and 20 weeks' gestation were matched with 89 chromosomally normal samples. Compared with controls, trisomy 21 pregnancies exhibited significantly elevated levels of all three peptides, whereas trisomy 18 gestations gave rise only to significant elevation of ahCG. Female fetuses in both the trisomy 21 and trisomy 18 pregnancies provided significantly elevated levels of hCG and bhCG compared to their male counterparts. On converting the values to multiples of the median, it was determined that 6 of 7 trisomy 18 samples had abnormally elevated alpha/beta ratios, as did 6 of 21 Down's syndrome pregnancies. Further, 11 of 21 trisomy 21 gestations had abnormal amniotic fluid hCG levels. Using only ahCG, bhCG and their ratio, a 61 per cent sensitivity was found for these trisomies, with a 96 per cent specificity.

OBJECTIVE: To characterize the extent and sources of imprecision in histologic dating of the endometrial biopsy. DESIGN: Duplicate endometrial biopsies from 25 women were dated by five evaluators on two separate occasions to evaluate the overall precision of the measure. Using variance component analysis, estimates of intrauterine, intraevaluator, and interevaluator variability were determined. SETTING: Samples were obtained during outpatient fertility testing. Evaluators were colleagues at the same institution. PATIENTS, PARTICIPANTS: Women presenting with infertility undergoing routine evaluation. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Variability in histologic dating of the endometrium. RESULTS: Inconsistencies between evaluators accounted for 65% of the observed variability, whereas 27% was because of inconsistencies in duplicate readings by the same evaluator. Regional differences in the uterus accounted for only 8% of the total variability. CONCLUSIONS: The overall error from these sources have the potential to result in a substantial false-positive rate for diagnosis of luteal phase defect.

Current knowledge supports the view that nonviral organisms may be responsible for repeated pregnancy wastage through chronic or recurrent occupancy in the maternal reproductive tract. However, two forms of evidence that would establish more clearly such a role lack for all of the organisms presented: recovery of the same organism from the products of conception in successive pregnancy losses, and demonstration of improved pregnancy outcome following specific treatment in a randomized prospective controlled trial. While acquisition of such data is scientifically justified, the necessary study designs may be viewed as unethical if the body of information derived from circumstantial cases and therapeutic trials using historical controls only continues to shape clinical opinion. Further confirmation of a specific role in pregnancy wastage for any of these organisms eventually will have to address the mysterious discrepancy between the prevalence of colonization and the incidence of sporadic and recurrent abortion purportedly due to the organism.
