ABSTRACT
OBJECTIVE: Interleukin-6 (IL-6) is an inflammatory cytokine that has been shown to be elevated in the amniotic fluid of patients with preterm labor. On the other hand, interleukin-10 (IL-10) is an anti-inflammatory cytokine that has been shown to inhibit the synthesis of other cytokines. We hypothesized that amniotic fluid IL-10 in the early second trimester is low in patients who subsequently develop preterm labor, and because of its deficiency, excessive inflammatory responses associated with IL-6 elevation lead to preterm labor and delivery. STUDY DESIGN: Amniotic fluid IL-6 and IL-10 levels were measured in 96 women who underwent genetic amniocentesis between 15 and 23 weeks' gestation. Levels of IL-6 and IL-10 were measured by immunoassay and correlated with demographic and pregnancy outcome information. RESULTS: Fifteen patients delivered at or before 36 weeks and 81 patients delivered after 36 weeks. There was an inverse correlation between amniotic fluid IL-10 concentration and gestational age at delivery. Similarly, an inverse correlation also existed between amniotic fluid IL-6 concentration and gestational age at delivery. CONCLUSIONS: Both IL-10 and IL-6 levels in second-trimester amniotic fluid obtained at the time of genetic amniocentesis appeared to be higher in patients who subsequently developed preterm delivery. Therefore, low amniotic fluid IL-10 production during the second trimester does not seem to be an etiology for preterm labor.

OBJECTIVE: To determine the incidence of positive blood cultures and if the results affect the clinical management or the duration of hospital stay in patients with acute pelvic inflammatory disease (PID). STUDY DESIGN: Retrospective study of all patients hospitalized with a diagnosis of acute PID from January 1, 1996, to December 31, 1997. RESULTS: Of 93 patients in the study, 3 had significant bacterial growth from blood culture specimens. The results of blood culture specimens did not affect clinical management. CONCLUSION: Routine specimens for blood culture may not be needed from patients hospitalized with acute PID.

OBJECTIVE: The object of the study was to determine the necessity of routine fetal karyotyping in patients undergoing amniocentesis for elevated maternal serum alpha-fetoprotein (AFP). METHODS: Data were collected retrospectively on patients under age 35 who underwent amniocentesis for elevated maternal serum AFP at the University of Medicine and Dentistry of New Jersey, New Jersey Medical School, Newark, New Jersey, between 1 January 1986 and 31 March 1995. A total of 537 patients with maternal serum AFP values greater than 2.5 multiples of the median were included in the study. RESULTS: Of 509 patients in the group with normal amniotic fluid AFP, 505 had a normal karyotype (specificity 94.9%, negative predictive value 99.2%). One of 28 patients in the group with an elevated amniotic fluid AFP demonstrated an abnormal karyotype (sensitivity 20%, positive predictive value 3.6%). CONCLUSIONS: Routine fetal chromosomal analysis of amniotic fluid amniocytes may not be necessary in patients with a normal level of amniotic fluid AFP. A fetal karyotype is recommended in those patients with an elevated amniotic fluid AFP.

Autoimmune polyglandular syndrome may complicate pregnancy and be confused with hyperemesis gravidarum as a cause of hypoglycemia and electrolyte imbalance in the first trimester of pregnancy. Autoimmune polyglandular syndromes are uncommon disorders characterized by the development and presentation of multiple endocrine and organ dysfunction. To our knowledge, we present the first case of an autoimmune polyglandular syndrome complicating pregnancy. A 26-year-old woman, gravida 5 para 3 at 12 weeks gestation, presented with hyperemesis and signs and symptoms consistent with adrenal insufficiency and hypothyroidism. Evaluation revealed autoimmune polyglandular syndrome type II. Autoimmune polyglandular syndromes are a myriad group of diseases characterized by polyglandular dysfunction. These syndromes should be kept in mind when dealing with pregnant patients presenting with hyperemesis and an electrolyte imbalance who do not improve with the usual treatment for hyperemesis. An endocrine dysfunction such as polyglandular syndrome may exist.

OBJECTIVE: To compare the rates of clinical amnionitis and endometritis in patients with premature rupture of membranes (PROM), using endocervical prostaglandin E2 (PGE2) gel for induction of labor versus immediate oxytocin induction of labor. METHODS: We randomized 118 patients to receive either endocervical 0.5 mg of PGE2 gel (study group) or immediate oxytocin induction of labor (control group). If labor was not established in the group receiving PGE2 gel in 24 hours, intravenous oxytocin was given in incremental doses. The rates of clinical amnionitis and endometritis in the two groups were analyzed. Also compared were hours of labor, duration of rupture of membranes and number of vaginal examinations. Student t test, chi 2, or Wilcoxon rank-sum test were used for statistical analysis, as appropriate. P < .05 was considered significant. RESULTS: The rates of clinical amnionitis were 5.3% in the PGE2 group and 8% in the control group. Endometritis developed in 1.7% of PGE2 patients and 3.2% of controls. These differences in maternal infection rates were not statistically significant. The two groups were comparable with respect to age, parity, and antepartum group B streptococcal colonization. No significant differences in hours of labor, duration of ruptured membranes, or vaginal examinations were observed. Neonatal outcome data (mean birth weight, Apgar scores at 1 and 5 minutes, Apgar score less than 7 at 5 minutes) were not statistically significant. CONCLUSION: Endocervical placement of 0.5 mg of PGE2 gel does not increase the incidence of clinical amnionitis and endometritis in patients with PROM at term when compared with immediate induction of labor with oxytocin.

Tuberculosis (TB) during pregnancy and in the perinatal period was once considered to be an infrequent event in the United States. After a decade of steady decline, however, the disease has begun a resurgence. According to the CDC, a 20% increase in the number of reported cases occurred between 1985 and 1992. The factors associated with this increase are the emergence of human immunodeficiency virus (HIV) infection, the development of drug-resistant organisms, substance abuse, homelessness, and immigration. Environmental factors promoting transmission can be found in overcrowded areas such as correctional facilities, nursing homes, hospitals, and migrant-worker camps. For a large number of medically underserved women, the obstetrician is the only interface with medical care, as most of these patients do not have primary-care providers. It is important, therefore, that health-care providers recognize the clinical symptoms of TB and follow the recognized guidelines for antenatal screening for TB because the omission of these steps can lead to potentially disastrous sequelae in the fetus and neonate.
ABSTRACT
The object of this study was to determine if a correlation exists between the resistance index (RI) of the umbilical artery, the RI of the fetal renal artery, and hourly urine output by fetuses of normal pregnancies. Doppler flow study of the fetal renal artery and the umbilical artery was performed in 110 fetuses between 19 and 40 weeks' gestation. Color and pulse wave Doppler was used to obtain the flow velocity waveforms. The RI of the flow velocity waveforms was calculated. Fetal bladder volume was calculated by transverse, anteroposterior, and longitudinal diameters obtained from coronal and transverse sonographic images of the fetal urinary bladder. The difference in bladder volume at 30-minute intervals was used to determine hourly urine output. Gestational age has a positive linear association with fetal urine output (P < 0.01). The RI of the fetal renal artery has a negative linear association with gestational age (P < 0.05). The RI of the umbilical artery decreased with an increase in gestation age (P < 0.01). There was a significant correlation between the RI of the umbilical artery (P < 0.01) and the fetal renal artery (P < 0.05) and hourly urine output by the fetus. The RI of the fetal renal artery decreased with gestational age. Hourly urine output of the fetus increased with gestational age. The RI of the umbilical artery and the fetal renal artery had a significant correlation with fetal urine output.

OBJECTIVE: The purpose of this retrospective study was to compare the clinical outcome and characteristics of pelvic inflammatory disease (PID) complicated by tubo-ovarian abscess (TOA) with PID without TOA. METHODS: Chart reviews were performed for all PID admissions to the University of Medicine and Dentistry of New Jersey-University Hospital, Newark, NJ, from January 1, 1992, to December 31, 1993. RESULTS: The incidence in this study of TOA based on sonographic evidence of a complex adnexal mass was 18%. The major differences between the patients with and without TOAs were 1) history of hospitalization for PID: 68% (13/19) vs. 29% (25/85); 2) increased erythrocyte sedimentation rate: 82 vs. 41 mm/h; 3) increased WBC count on admission: 16,200 vs. 14,700/ml; 4) failure to respond to initial antibiotic therapy; and 5) longer hospital stay: 7.8 vs. 4.4 days, respectively. Surgical intervention was required in 3 patients: 2 patients who had TOAs and 1 patient who did not have a TOA by clinical examination or by ultrasound. CONCLUSIONS: Despite longer hospital stays and blood tests suggesting more severe disease processes, PID complicated by TOA is usually responsive to intravenous (IV) antibiotic therapy without the need for surgical intervention.
ABSTRACT
BACKGROUND: Although cytomegalovirus (CMV) is an uncommon cause of viral hepatitis during pregnancy, a definitive diagnosis is important because of the potential for congenital CMV. In the case reported here, a diagnosis of hepatitis caused by CMV was made after the more common viral pathogens had been ruled out. CASE: A 17-year-old, 12-week pregnant patient was evaluated for fever and right upper quadrant tenderness. A serologic evaluation revealed elevated liver function levels and a positive maternal serology for CMV IgM. A diagnosis of hepatitis caused by CMV was made after the more common viral pathogens and drug-induced hepatitis had been ruled out. She was counseled about the potential effects of CMV on her fetus. CONCLUSION: A step-wise approach to the diagnosis of viral hepatitis during pregnancy is needed to determine the etiology because a potential teratogenic virus may be involved.
ABSTRACT
OBJECTIVE: Our purpose was to study the short-term effect of maternal cocaine abuse on blood flow of the fetal kidney and the fetal hourly urine output. STUDY DESIGN: Thirty-three pregnant patients of various gestational ages with a history of cocaine abuse were studied. Patients were included if the urine specimen was positive for cocaine on the day of study. Patients were excluded if the urine specimen was positive for any other vasoactive substances or medications. Color and pulsed wave Doppler studies were used to obtain the flow velocity waveform of the fetal renal artery. The resistance index was calculated from systolic and diastolic values of flow velocity waveforms, Longitudinal, transverse, and anteroposterior diameters of the fetal urinary bladder were measured from transverse and coronal images at their maximum diameters, and the bladder volume was calculated. The hourly urine output of the fetus was measured from the difference in the bladder volume at half-hour intervals. As controls, 110 normal pregnancies between 19 and 40 weeks were similarly studied for normal values. The resistance index of the fetal renal artery and the hourly fetal urine output of the two groups were compared. RESULTS: The resistance index of the fetal renal artery of normal pregnancies had a negative association with gestational age (p < 0.05). Cocaine-exposed fetuses had a significantly higher resistance index of the renal artery (p < 0.01) than did normal fetuses of corresponding gestational ages. A decrease in the hourly urine output of cocaine-exposed fetuses was observed, compared with normal controls of corresponding gestational ages (p < 0.001). CONCLUSION: The resistance index values of fetal renal artery and fetal urine output were affected by maternal cocaine abuse.

A comparison of relevant statistics from National Maternity Hospital, Dublin, Ireland and University Hospital, Newark, New Jersey, USA, for the years 1983-1989, revealed that after removal of major confounding factors, such as a fourfold difference in < 2500 gram births and an about tenfold discrepancy in the frequency of lethal congenital defects, the perinatal survival rates in all weight categories were significantly higher in the American center. The findings suggest that optimum perinatal results could not be achieved in an American high risk center with the approximately 6% abdominal delivery rate favored in Dublin. The same data also suggest, however, that the 17.5% rate of abdominal deliveries in Newark was unnecessarily high. The favorable impact of the relatively liberal use of cesarean section might have been derived in this study from a marked reduction of in utero losses, in the absence of an identifiable effect upon the rate of neonatal mortality.

OBJECTIVE: The purpose of this study was to determine the epidemiology of sexually transmitted diseases (STDs) among pregnant adolescents. METHODS: Charts of all patients (n = 735) who attended the Maternal and Infant Care Clinic at University Hospital, Newark, NJ, between July 1, 1991, and June 30, 1992, were reviewed for STDs which included gonorrhea, chlamydia, syphilis, and human immunodeficiency virus (HIV). At the first prenatal visit, each registrant had endocervical specimens obtained to detect gonorrhea and chlamydia. A serum sample was obtained for syphilis screening. HIV testing was made available to all patients and testing was done on a voluntary basis. The same STD screening that was done at the initial visit was repeated at 28 and 36 weeks. RESULTS: Twenty-five percent of patients tested positive for one or more STDs. The mean patient age was 17.3 years. The mean gestational age at first visit was 19.5 weeks. The mean number of visits was 7.3. The following STDs were identified: 4.8% of patients tested positive for gonorrhea, 20.9% tested positive for chlamydia, and 1.7% tested positive for syphilis. Twenty-one percent of patients had a positive STD diagnosed at the initial visit. Another 4.8% of patients had an STD diagnosed at some time after the initial visit when the initial screen was negative for STDs. An additional 1% of patients who initially tested positive for an STD had subsequent screening which revealed another STD (different organism). Seven patients tested HIV positive. Sixty-one percent of patients with STDs agreed to HIV testing. One patient had HIV coexistent with another STD. CONCLUSIONS: Pregnant adolescents are at risk for multiple STDs. HIV testing should be offered. STD screening should be repeated in the third trimester in adolescent patients.
ABSTRACT
Based on their yearly clinical statistics for 1983-1989, the cesarean section and stillbirth rates at National Maternity Hospital (Dublin), where the patients are generally white, and University Hospital (Newark), where the patients are predominantly black, were compared. After adjusting for confounding factors, such as unregistered mothers admitted subsequent to fetal demise, differing rates of < 2500 g births and lethal congenital defects, the overall rates of intrauterine fetal demise were identical. When analyzed according to birth weights, in all weight groups, the stillbirth rates were significantly lower in Newark than in Dublin. However, for every 1000 births, more < or = 2500 g fetuses died in utero in Newark than in Dublin. This trend was reversed in the > 2500 g group, where the respective rate at National Maternity Hospital exceeded that of University Hospital more than twice. The latter result largely derived from an almost 7-fold higher rate of intrapartum deaths in the > 2500 g weight group at National Maternity Hospital as compared to University Hospital. When projected against prevailing American statistics, which reflect a stillbirth rate about twice as high among blacks than among whites, the results suggest that the management patterns favored in Newark, including a relatively liberal cesarean section rate (17.5% versus 5.8%), affected the rate of in utero losses favorably.

OBJECTIVE: To compare the epidemiology and hospital course of patients with acute salpingitis with and without coincident human immunodeficiency virus (HIV) seropositivity. METHODS: Patients admitted to the UMDNJ-University Hospital in Newark, New Jersey from January 1, 1991, to December 31, 1991, with acute salpingitis were studied. RESULTS: Eight percent of all hospitalized patients with acute salpingitis were HIV-positive. The mean age of the HIV-negative group was 25.4 compared with 29.6 years in the HIV-positive group. Gonorrhea and chlamydia were present in 49% and 22%, respectively, in HIV-negatives and in 40% and 20% of HIV-positives. Two of 5 (40%) HIV-positive patients had tuboovarian abscesses compared with 12 of 59 (20%) HIV-negative patients. Three of 5 (60%) HIV-positive patients had admission WBC counts fewer than 10,000/mm(3) compared to 6 of 59 (12%) of HIV-negatives (P = 0.024). The hospital stay was 5.4 days for HIV-positives and 5.8 days for HIV-negatives. CONCLUSIONS: Eight percent of hospitalized patients with acute salpingitis were HIV-seropositive. Neisseria gonorrhoeae and chlamydia were commonly found organisms in both groups. The initial WBC count was lower for HIV-positive patients. The hospital course of both groups was similar.
ABSTRACT
A comparison of the yearly statistics of National Maternity Hospital (Dublin) and University Hospital (Newark) was undertaken for the years 1983-1989. The findings appear to indicate that after the elimination of major confounding factors, the substantially higher rates of Caesarean section in Newark (17.5% versus 5.8%) did not bring about a measurable reduction in the rate of neonatal losses. The impact of paediatric care upon the respective neonatal outcomes could not be assessed on the ground of the reviewed data.

Chorioamnionitis substantially increases fetal and neonatal morbidity. Infants born to women with chorioamnionitis have a fourfold increase in neonatal morbidity. If this condition could be predicted before the clinical manifestation and thereby treated earlier, an improved perinatal outcome might reasonably be expected. Based on the in vitro model of bacteria-induced vasoconstriction and pulmonary hypertension noted in sheep and lambs after exposure to the spent medium of a bacterial culture, we theorized that infected amniotic fluid may produce vasospasm of umbilical and placental vessels, reduce fetal perfusion, and increase perinatal asphyxia, morbidity, and mortality. Umbilical vessel vasospasm may be detected by measuring the systolic-diastolic ratio (S/D) of the umbilical artery. Continuous Doppler flow studies of the umbilical artery S/D were performed prospectively on 51 patients with premature rupture of membranes who were not in labor. The most recent test, done within 1 day of delivery, was compared with pregnancy outcome. Ten subjects developed clinical chorioamnionitis, of whom none had an abnormal S/D. Six of 41 women without clinical chorioamnionitis had abnormal S/Ds. These data do not support the use of Doppler measurement of the S/D as a predictor of clinical chorioamnionitis.
