Ricciotti, Calayag P, Abbott, Ludmir. Obstetric outcome after failed termination of pregnancy--a report of two cases.. Am J Obstet Gynecol. 1995;173(5):1619-20.
Unsuccessful therapeutic abortion resulting in continued viability of the fetus is rare. No case of a live birth after unsuccessful vacuum curettage has been published. We report two cases with persistent pregnancies after failed termination, with outcomes complicated by premature rupture of membranes and preterm delivery.
Ricciotti, Burke, Kobelin, Slomovic, Ludmir. Ultrasound evaluation of cervical shortening after loop excision of the transformation zone (LETZ).. Int J Gynaecol Obstet. 1995;50(2):175-8.
OBJECTIVES: To assess cervical shortening after loop excision of the transformation zone (LETZ), and confirm the validity of ultrasound measurement of cervical length. METHODS: Subjects (n = 29) were patients at the colposcopy clinic of Beth Israel Hospital who underwent vaginal ultrasound measurement of cervical length before and after LETZ. The pathologic specimen was measured by ruler. Mean cervical length (+/- S.D.), mean percentage (+/- S.D.) of cervical length removed, and correlation (r) between ultrasound and pathology specimen measurement were determined. RESULTS: Mean (+/- S.D.) cervical length measurements prior to LETZ were 3.2 +/- 0.9 cm and after LETZ were 2.6 +/- 0.9 cm, with a difference of 0.7 +/- 0.4 cm. The pathologic specimen (mean +/- S.D.) was 0.6 +/- 0.3 cm. The correlation between ultrasound and pathology measurement was r = 0.9 (p = 0.0001). Mean (+/- S.D.) cervical length was shortened by 22 +/- 12%. CONCLUSIONS: There is excellent correlation between ultrasound and ruler measurement of the cervix. There is significant cervical length shortening after LETZ, but further study is needed to see whether this persists or leads to pregnancy complications.
Ricciotti, Chen, Sachs B. The role of obstetrical medical technology in preventing low birth weight.. Future Child. 1995;5(1):71-86.
Technology plays an important role in the practice of medicine, and it is essential that controlled clinical trials be conducted before new technologies are widely disseminated. In this article, information from the medical literature is summarized and critiqued for several common obstetric technologies which are aimed at reducing the incidence or sequelae of low birth weight and preterm birth. These technologies include home uterine activity monitoring, tocolytic drugs to suppress uterine contractions, corticosteriods to accelerate fetal lung maturity, bed rest to prevent preterm delivery, delivery methods, multifetal pregnancy reduction, and cervical cerclage. A major challenge to the practice of medicine is to find effective ways to modify physician behavior to encourage the use of proven, effective technologies, and discourage the use of unproven, ineffective technologies. Despite widespread use, most obstetrical technologies appear to have had little impact on reducing the incidence of low birth weight or preterm births, as rates of low birth weight and preterm birth have not decreased appreciably in the past 25 years. Uncovering the basic mechanisms responsible for the onset of preterm labor will undoubtedly facilitate the discovery of new technologies to prevent low birth weight and preterm births.
