Sixty-six cerclages were performed by one surgeon in 46 patients with documented cervical incompetence. The mean operative blood loss was 25 ml, and the mean operating time was 18 minutes with no postoperative morbidity. Fifty-five of the pregnancies were carried for at least 37 weeks, eight were delivered before 37 weeks, and three are continuing. Six of the eight preterm deliveries were a result of factors unrelated to cervical incompetence. The two remaining preterm births were probably also unrelated because one occurred 8 days after emergent cerclage placement and the other occurred 12 weeks after the procedure, both as a result of premature rupture of membranes. There were no cesarean deliveries related to the Shirodkar suture. The efficacy of the procedure was demonstrated by a corrected perinatal survival rate of 100% and term delivery of 88%. (Since this article was written all three of the undelivered patients were delivered of infants after 37 weeks' gestation for a term delivery rate of 88% with 100% neonatal survival

Ballantyne syndrome is a condition of multiple causes and is characterized by maternal, placental, and fetal edema. We describe the first case of Ballantyne syndrome in a patient whose fetus had ultrasonographic demonstration of an aneurysm of Galen's vein

Chorioamnionitis during pregnancy is a common diagnostic dilemma for the obstetrician. Fast and accurate diagnosis poses the most significant problem. Since leukocytes are known to be released in response to infections, examination of amniotic fluid for their presence is an important part of the evaluation for chorioamnionitis. These neutrophils contain several esterases that are not present in serum, urine, or vaginal secretions. The esterases are not influenced by bacteria or by commonly used drugs. We have previously described the reliability of leukocyte esterase (LE) activity for the detection of chorioamnionitis in term pregnancies uncomplicated by other diseases. A prospective study was performed to assess the presence or absence of LE activity to establish normal values in amniotic fluid at various gestational ages prior to term before its use as a possible predictor for chorioamnionitis. Sterile amniotic fluid specimens were obtained from 13 patients undergoing second trimester genetic amniocentesis (with gestational ages varying from 15 to 19 weeks) and from 11 patients with a wide variety of medical problems, undergoing amniocentesis for Rh sensitization or lung maturation studies (with gestational ages ranging from 25 to 27 weeks). All patients with ruptured membranes or preterm labor were excluded. Each amniotic fluid sample was divided into two parts, one of which was transported to the laboratory for aerobic and anaerobic cultures and the other used for LE activity detection as measured by dipstick. The LE results were retrospectively compared with the results of the cultures. LE activity was always found to be negative when the culture results were negative. negative.(ABSTRACT TRUNCATED AT 250 WORDS)

Isolated herpes simplex virus encephalitis in pregnancy is a rare illness with an elusive diagnosis. We describe the second patient to survive this disease and the first to have no sequelae, because of prompt diagnosis and treatment with acyclovir

Accurate and rapid diagnosis of chorioamnionitis poses a major diagnostic dilemma. We previously reported that leukocyte esterase activity in amniotic fluid, as measured by dipstick assay, could be used as an aid in the diagnosis of chorioamnionitis. This study examines the effectiveness of an in vitro spectrophotometric assay of esterase activity in amniotic fluid. We define baseline levels of esterase activity in uninfected amniotic fluid and demonstrate a quantitative increase when infection is present. Fifty-seven amniotic fluid samples obtained at second- and third-trimester amniocenteses were divided into three parts, one for culture and two for a comparison of esterase activities by the dipstick and spectrophotometric methods. In this study, the spectrophotometric assay, because of its higher specificity and sensitivity in the determination of elevated esterase activity, was shown to be more reliable for predicting chorioamnionitis than either the dipstick or culture method

Congenital hereditary fructose intolerance is associated with the inability to tolerate fructose and carbohydrates, which are converted into fructose. We describe management of a pregnancy complicated by this disease in the mother and its implications for the neonate
