ABSTRACT
OBJECTIVES: This study asked the following questions: 1) Does HIV testing in pregnancy identify women who previously were not known to be HIV positive? 2) When in pregnancy are women identified as HIV infected? 3) Does HIV seroconversion occur during the prenatal care period? METHODS: Medical records of 97 women from two primarily indigent care hospitals in Houston, TX who were found to be HIV positive at delivery were reviewed to determine if they had tested positive during the prenatal care period. Demographics and time of gestation of the prenatal testing also were recorded. The outcome measures were: 1) number of women found positive during prenatal care; 2) week of gestation at discovery of HIV positivity; and 3) number of women seroconverting between the initiation of prenatal care and delivery. RESULTS: Thirty women were known to be HIV positive prior to pregnancy. Fifty-six women were found to be positive during prenatal care and the seropositivity of 44 was discovered before the 34th week of pregnancy. Ten women were found to be positive at their first prenatal visit, which occurred after the 34th week. Date of testing was unknown for two women. Eleven women who received no prenatal care were found to be HIV positive at delivery. There were no seroconversions while women were under prenatal care. CONCLUSIONS: HIV testing at delivery did not find any HIV-positive women who had tested negative during prenatal care. Testing is very important for women who do not receive prenatal care. Making certain that high-risk women get into prenatal care also is very important.

Episiotomy continues to be a frequently used procedure in obstetrics despite little scientific support for its routine use. Although episiotomy does decrease the occurrence of anterior lacerations, it fails to accomplish the majority of goals stated as reasons for its use. Episiotomy does not decrease damage to the perineum but rather increases it. The midline episiotomy increases the risk for third-degree and fourth-degree lacerations. Episiotomy fails to prevent the development of pelvic relaxation and its attendant complications. Rather than decreasing maternal morbidity, episiotomy increases blood loss and is related to greater initial postpartum pain and dyspareunia. It has been associated with a more difficult and lengthy repair as measured by the need for suture material and operating room time. The claims of a protective effect on the fetus in shortening the second stage of labor, improving Apgar scores, and preventing perinatal asphyxia have not been borne out. The value of episiotomy use on a routine basis bears scientific examination in prospective, randomized, controlled trials. These types of trials are certainly achievable, ethically correct, and much needed. Until these trials are completed and published, obstetricians should not routinely perform the procedure but rather determine the need for episiotomy on a case-by-case basis.

This article examines the legal implications of studies showing that the probability of maternal-to-infant human immunodeficiency virus transmission can be reduced by physician interventions. These interventions require knowledge of a pregnant woman's human immunodeficiency status. Hence the offering of human immunodeficiency virus testing has become a standard of care in pregnancy. This standard of care is examined with respect to the following: (1) the physician's legal duty to the infant, (2) negligence for failing to test, (3) liability when testing only reduces the probability of transmission, (4) damages, (5) informing women about the results of their testing, (6) protecting against liability, and (7) dealing with human immunodeficiency virus-infected pregnant women. It is concluded that the physicians are likely to have legal difficulties if a human immunodeficiency virus-infected baby is born to a woman who was not offered testing or if testing is done without documenting consent. Suggestions are made for reducing liability when testing is done, when patients refuse testing, and when one is caring for human immunodeficiency virus-infected women.

OBJECTIVES: To assess the knowledge of universal precautions for the delivery and operating rooms by residents and students and to evaluate their use of universal precautions. STUDY DESIGN: Obstetrics and gynecology (ob/gyn) residents (n = 30) and students (n = 31) from an inner-city, teaching hospital were polled by anonymous questionnaire to assess their knowledge of the appropriate barrier equipment for certain ob/gyn procedures. To determine actual compliance with universal precautions, 459 ob/gyn procedures were observed. We noted the use of appropriate barrier equipment for each procedure: gloves for pelvic exam and face shields, gowns, gloves, and booties for vaginal delivery, cesarean delivery, and dilation and curettage. The True Epistat statistical software program was used to perform simple regression analysis. RESULTS: Thirty residents (100%) knew the appropriate barrier equipment required for each type of procedure performed. One student (< 1%) did not know that booties were appropriate for the surgical procedures. Rationale for lack of compliance with universal precautions elicited by the questionnaire included time constraints (64%), inconvenience (52%), and presumption that patient was not infected (34%). The observed rate of compliance with universal precautions by participants indicates that individual compliance was inversely related to the years of experience (overall compliance rate of students was 96%; for first-year residents, 92%, second-year residents, 89%, third-year residents, 84%, fourth-year residents, 78%; r = -0.9918, P = 0.0009). CONCLUSIONS: Knowledge regarding universal precautions was nearly 100%, while overall observed compliance was only 89%. Compliance with universal precautions was better among students (96%) than among residents (88%). Compliance with universal precautions was inversely related to years of experience.

OBJECTIVE: To determine the prevalence of cutaneous anergy in pregnant and nonpregnant women who are seropositive for human immunodeficiency virus. METHODS AND MATERIALS: The medical records of 159 women seropositive for human immunodeficiency virus were reviewed. Demographic characteristics and tuberculin skin test results were abstracted from the chart. Tuberculin skin testing was performed by the Mantoux method (5 tuberculin units of purified protein derivative injected intradermally). Anergy testing was performed using any two of the three following antigens; tetanus toxoid, mumps, or Candida skin test antigen. A positive tuberculin test was defined as induration of 5 mm or more, and a positive test for the other antigens was defined as any amount of induration over the skin test area. Anergy was defined as any amount of induration to the other antigens. A CD4+T lymphocyte count was obtained at the time of skin testing. Continuous variables were analyzed using the Mann Whitney-U test. Categorical data were analyzed with the chi-square or Fisher's exact test as appropriate. A two-tailed P value < 0.05 was considered significant. RESULTS: There were 102 nonpregnant and 57 pregnant women who returned to have their skin test results read. There was no significant difference in the prevalence of positive, negative or anergic skin test results between groups. The CD4+T lymphocyte count (mean +/- standard deviation) in patients with anergic results was similar between pregnant (375 +/- 256/mm3) and nonpregnant (358 +/- 305/mm3) women (P = 0.64). CONCLUSION: The prevalence of cutaneous anergy is similar among pregnant and nonpregnant women seropositive for human immunodeficiency virus.

BACKGROUND: The rare entity of vasa previa occurs when fetal vessels lying between the amniotic and chorionic membranes cross the cervical os. This report presents a case that was associated with vessel compression and concomitant adverse effects on fetal hemodynamics. CASE: A 23-year-old nulliparous woman at 36 weeks' gestation developed persistent, progressive severe variable decelerations several hours after spontaneous rupture of the membranes, resulting in a decision to perform a cesarean. At delivery, fetal vessels were noted in the membranes near the cervical os, leading into a marginally inserted cord. The decelerations were attributed to compression of the unprotected umbilical arteries by the fetal head. CONCLUSION: Vasa previa often results in fetal death and may be associated with fetal hemorrhage, but lack of bleeding does not exclude the existence of vasa previa. Altered fetal hemodynamics from varying degrees of vessel compression by the presenting part during labor may result in hypoxia and acidosis. A high index of suspicion is necessary to make the diagnosis and institute proper, timely management.
