Risk factors for ectopic pregnancy: a case-control study.

AIM: To identify the risk factors for ectopic pregnancy. METHODS: We conducted a prospective case-control study for the role of several risk factors in the occurrence of ectopic pregnancy in Turkey. A total of 225 cases and 375 controls were compared for sociodemographic characteristics, cigarette smoking, obstetric, gynaecological, surgical histories, the presence or absence of assisted conception and contraceptive usage. RESULTS: The main risk factors for ectopic pregnancy were prior ectopic pregnancy (adjusted odds ratio (AOR): 13.1) and a history of infectious reproductive system (AOR for pelvic inflammatory disease: 6.8). Other risk factors found to be associated with an increased risk for ectopic pregnancy were multisexual partner (AOR: 3.5), history of infertility (AOR: 2.5), induced conception cycle (AOR: 3.4), current intrauterine device usage (AOR: 3.2), prior Caesarean section (AOR: 2.1) and cigarette smoking at the time of conception (AOR=1.7). On the contrary, barrier methods were protective from ectopic pregnancy (AOR: 0.4). CONCLUSIONS: The increased awareness and knowledge of risk factors have enabled an early and accurate diagnosis of ectopic pregnancy. This study has found prior pelvic infection to be a major aetiological factor for ectopic pregnancy. Furthermore, other factors found to be associated with ectopic pregnancy, such as prior ectopic pregnancy, infertility history and induced conception cycle, may be the result of a previous pelvic infection that may cause tubal sequelae. These factors are potential targets for intervention and modification.

Severe perineal lacerations in nulliparous women and episiotomy type.

OBJECTIVE: To determine the patient-related factors associated with severe perineal lacerations in nulliparous women and to evaluate the effect of episiotomy type on the risk of severe perineal tears. STUDY DESIGN: In all, 400 nulliparous women admitted in labor between June and December 2001 were prospectively enrolled. Maternal height, perineal length, fetal birth weight, fetal head circumference, and severe perineal lacerations (third and fourth degrees) were recorded. RESULTS: The rate of severe perineal lacerations was 2% (8/400); 3% with midline, 1% with mediolateral groups. In patients with severe lacerations, perineal length was significantly (p < 0.001) shorter and the head circumference of their babies in the midline significantly (p < 0.05) greater than normal, and birth weights were also significantly (p < 0.05) greater in the mediolateral group. A cut-off value for perineal length of 3.05 cm was found for severe lacerations in the midline group. CONCLUSION: If episiotomy is to be performed, it must be borne in mind that patients with a perineal length of < or = 3 cm have an elevated risk of severe perineal lacerations, and if clinical or ultrasound examination suggests that the fetal head is large, mediolateral episiotomy may be preferred. Otherwise, midline episiotomy must be considered.
