Does a large infant head or a short perineal body increase the risk of obstetrical perineal trauma?

Background: Perineal trauma after vaginal delivery can have significant long-term consequences. It is unknown if a larger infant head circumference or smaller maternal perineal anatomy are risk factors for perineal trauma after vaginal delivery.

Methods: We conducted a prospective cohort study of low-risk nulliparous women.

Contribution of the second stage of labour to pelvic floor dysfunction: a prospective cohort comparison of nulliparous women.

Objective: Maternal expulsive efforts are thought to damage the pelvic floor. We aimed to compare pelvic floor function and anatomy between women who delivered vaginally (VB) versus those with caesarean delivery (CD) prior to the second stage of labour.

Design: Prospective cohort.

Promotion rates for assistant and associate professors in obstetrics and gynecology.

Objective: To estimate promotion rates of physician faculty members in obstetrics and gynecology during the past 30 years

Methods: Data were collected annually by the Association of American Medical Colleges from every school between 1980 and 2009 for first-time assistant and associate professors to determine whether and when they were promoted. Data for full-time physician faculty were aggregated by decade (1980-1989, 1990-1999, 2000-2009). Faculty were included if they remained in academia for 10 years after beginning in rank.

Retention of entry-level faculty members in obstetrics and gynecology.

Objective: The purpose of this study was to examine retention rates of entry-level physician faculty members in obstetrics and gynecology.

Study Design: Ongoing data were collected by the Association of American Medical Colleges between 1981 and 2009 for full-time, entry-level assistant professors to determine whether they remained at their original departments, switched to another school, or left academia. Retention curves and 5- and 10-year retention rates at their original department and for academia were determined.

Trends in salaries of obstetrics-gynecology faculty, 2000-01 to 2008-09.

Objective: We sought to determine whether downward trends in inflation-adjusted salaries (1989-99) continued for obstetrics and gynecology faculty.

Study Design: Data were gathered from the Faculty Salary Survey from the Association of American Medical Colleges for academic years 2001 through 2009. We compared median physician salaries adjusted for inflation according to rank and specialty.
