RESUMEN

An experimental teat dip containing 0.5% hydrogen peroxide as the active ingredient was compared with a teat disinfectant also containing 0.5% hydrogen peroxide that is commercially available throughout North America. The study was conducted under conditions of experimental challenge with a positive control following the guidelines recommended by the National Mastitis Council. The efficacy of the test product and the positive control product were compared in 45 cows, with 89 total teats receiving each product after milking during a 10-wk study period. There was no significant difference between the experimental hydrogen peroxide product and the positive control in new intramammary infections caused by Staphylococcus aureus (27.0 and 18.0% in the treatment groups, respectively). Additionally, there was no significant difference between the experimental product (6.7%) and the positive control groups (4.5%) in new intramammary infections caused by Streptococcus agalactiae. Traditional analysis of teat skin condition changes supported improved teat skin condition with the test disinfectant. After accounting for the correlation of teats within cow, significant differences were also observed between the treatment groups for teat skin condition. The experimental hydrogen peroxide-based teat disinfectant provided efficacy similar to that of the positive control teat disinfectant, with significant improvement in teat skin condition and no adverse effects on teat end condition.

RESUMEN

During the period of 4 years between 1985 and 1988, 190 patients suffering from hyperemesis gravidarum (HG) were hospitalized at the Soroka Medical Center. From the 190 patients, 164 were followed up throughout their pregnancies and delivered at our Medical Center. The epidemiology of HG as well as the incidence of maternal complications and pregnancy outcome were analyzed and compared with 209 controls. The incidence of HG in our patient population was 6.3/1000 live births. The patients in the study group had fewer pregnancies and deliveries and more spontaneous abortions in the past than in the control population. Premature contractions and vaginal bleeding during the first trimester were more common among women with HG. Other complications of pregnancy were no more common than among controls. Women with HG in their current pregnancy had a lower incidence of spontaneous abortions (3.1%) as compared with previously reported rates in the general population (15%). Perinatal outcome was no different in women with HG than in the controls. Women with severe HG did not have statistically significant differences in the incidence of pregnancy complications and their pregnancy outcome was the same as in those without severe HG.

RESUMEN

Anemia, the decrease of the hemoglobin concentration with a consequent decrease in the hematocrit level, is a common disorder complicating pregnancies and is mostly due to iron deficiency. The increase of iron requirements, plasma volume, and the poor intake of iron constitute the principal causes of this deficiency. The present review summarizes the current literature regarding anemia during pregnancy and the parenteral iron therapy options.

RESUMEN

OBJECTIVE: To describe the maternal characteristics of pregnancy and perinatal outcome of primiparous women with preeclampsia, to determine the recurrence rate and to define the maternal risk factors for preeclampsia in subsequent pregnancies. METHODS: A retrospective cohort study. Two groups of patients were defined: the study group consisted of 380 primiparous women with preeclampsia, and in a control group of 385 primiparous women without preeclampsia. The patients were followed during their consecutive deliveries. Multiple logistic regression analysis was used to determine the independent risk factors for the recurrence of preeclampsia in the second pregnancy. RESULTS: In the study and the control group there were a total of 1207 and 1293 deliveries, respectively. Of the 380 primiparous women in study group, 305 (80%) were identified as suffering from mild preeclampsia, 64 (17%) from severe preeclampsia, 10 (2.6%) from super imposed preeclampsia and only one (0.3%) had eclampsia. Primiparous with severe preeclampsia had a significantly higher rate of preterm delivery then those with mild preeclampsia (34 versus 11% respectively, P<0.0001). In addition, the study group had significantly higher rate of perinatal mortality (3.4 versus 0.3%, P=0.013) and perinatal complications. The recurrence rate of preeclampsia was significantly higher in the study group (25% versus 1.9%, P<0.0001). When adjusted for confounding variables, gestational diabetes was strongly associated with the recurrence of preeclampsia in the second pregnancy (OR 3.72 95% CI 1.45-9.53). CONCLUSION: Primiparous women with preeclampsia are at an increased risk for recurrence in subsequent pregnancies. Gestational diabetes in primiparous women with preeclampsia is an independent risk factor for developing preeclampsia in the second pregnancy.

RESUMEN

OBJECTIVE: To evaluate maternal characteristics and neonatal and maternal birth outcome in cases of prelabor rupture of membranes (PPROM) in a non-selected parturient population. STUDY DESIGN: The study population consisted of 5660 singleton preterm births (24-36 weeks gestation) occurring between 1988 and 1997 at the Soroka University Medical Center in Israel. Parturients with no prenatal care were excluded from the study. A cross-sectional study was designed between two groups. The study group consisted of patients with PPROM (n=968) and the comparison group consisted of patients without PPROM (n=4692). The data were analyzed by SPSS package. Information was obtained using a computerized database based on detailed obstetrical records. Logistic regression was used to assess the contribution of different risk factors to PPROM. RESULTS: PPROM was associated with a significantly lower gestational age (24-32 weeks) and birth weight (<2500 g) than those with intact membranes. The rates of chorioamnionitis and urinary infection were found significantly higher in the PPROM group compared with women without PPROM (16.5 vs. 2.7%; 5.1 vs. 3.3%, respectively) (P<0.001). The rate of endometritis and bacteremia in the postpartum period were significantly higher in women with PPROM compared with controls 2.8 vs. 1.4%, (P=0.003) and 9.4 vs. 5%, (P=0.001), respectively. Total perinatal mortality rates were significantly higher in the group without PPROM 10.5 vs. 7.2% (P=0.01), however, rates of postpartum death were higher in the PPROM group 5.5 vs. 4% (P<0.01). When adjusted for recognized risk factors using logistic regression analysis, infection of amniotic fluid (OR=6.6) and genito-urinary tract infection (OR=1.64) remained the independent risk factors associated with PPROM. CONCLUSIONS: Infectious morbidity in patients with preterm prelabor rupture of membranes and preterm delivery remained an important risk factor for obstetrical and neonatal complications.

RESUMEN

OBJECTIVE: To determine whether congenital anomalies are associated with a high rate of neonatal morbidity in preterm birth. STUDY DESIGN: 312 singletons (22-36 wk) with congenital anomalies that were delivered preterm were compared with a random sample of 936 preterm singleton without congenital anomalies. Data was obtained using the computerized birth discharge records. Statistical analysis included univariate and multivariate logistic regression analyses. RESULTS: Three thousand five hundred and seventy-eight (3578) women with preterm births met the inclusion criteria (singleton with prenatal care). The prevalence of congenital anomalies in the study population was 8.7% (312/3578). Gestational age at delivery was significantly lower in the congenital anomaly group compared with the control (32.0+/-3.7 SD vs. 34.4+/-2.7 SD; p<0.001). The following pregnancy complications were higher in the group with congenital anomalies than in those without anomalies: severe pregnancy induced hypertension (PIH), hydramnions, oligohydramnion, intrauterine growth restriction (IUGR), fetal distress, cesarean section, malpresentation and mal position, abruption placenta, meconium stained amniotic fluid, 1 min Apgar score (<2), 5 min Apgar score (<7). Perinatal mortality rates in 28-32 wk and 33-36 wk were significantly higher in the group with congenital anomalies than in the control group. Neonatal morbidity data (necrotizing enterocolitis, respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, and sepsis) was available for 909 neonates (239 with congenital anomalies and 670 without congenital anomalies). After adjusting for gestational age, the presence of congenital anomalies remained strongly associated with neonatal morbidity (having one or more of the above mentioned conditions) (adjusted OR: 5.3, 95% CI 3.4-9.2). When adjusting for other confounding variables, congenital anomalies were strongly associated with neonatal morbidity (OR: 6.44, 95% CI 3.94-10.51), and perinatal mortality (OR: 3.08, 95% CI 2.04-4.65). In terms of attributable fraction in our population of preterm births, the proportion of neonatal morbidity and the proportion of perinatal mortality attributable to congenital malformation is 32% and 15%, respectively. CONCLUSION: Congenital anomalies in preterm birth are associated with a higher rate of pregnancy complications and are an independent risk factor for neonatal morbidity and perinatal mortality.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate whether maternal serum CA 125 determination in women with uterine bleeding has a prognostic value in the detection of women at risk for delivering a small-for-gestational-age neonate. STUDY DESIGN: The patients population consisted of women with uterine bleeding at a gestational age greater than 20 weeks. Patients with abruptio placentae, placenta previa, fetal distress and history of coagulopathy were excluded. Maternal serum CA 125 was measured at admission. Receiver operating characteristics curve analysis and logistic regression were used for statistical purposes. RESULTS: Fifty-nine women were enrolled into the study. Six of these had a small-for-gestational-age neonate, 8 had premature rupture of membranes and 33 delivered preterm. No relationship was found between maternal serum CA 125 concentrations and preterm delivery or PROM. Women who delivered a small-for-gestational-age infant (10.1%) had lower maternal serum CA 125 levels than those who delivered an appropriate-for-gestational-age infant (P < 0.02). Patients with uterine bleeding and serum CA 125 < or = 10 U/ml had a twofold risk to deliver a small-for-gestational-age neonate. Sensitivity, specificity, positive and negative predictive values were 66.6%, 79.2%, 26.6% and 95.4%, respectively. CONCLUSION: Our results show that a decreased maternal serum CA 125 concentration in women with uterine bleeding during the second half of pregnancy is of prognostic value in identifying those who will deliver a small-for-gestational-age infant.

RESUMEN

OBJECTIVE: To compare perinatal and maternal outcome between induced and spontaneous small-for-gestational-age (SGA) neonates at term and preterm deliveries. STUDY DESIGN: A cross-sectional study was designed and two groups were identified at each gestational age: study group - SGA neonates born after induction of labor, comparison group - SGA neonates born after spontaneous onset of labor. SGA was decoded as birth weight below 10th percentile. The population consisted of 367 consecutive SGA singleton preterm neonates (24-36 weeks' gestation) and 3921 term SGA neonates (37-42 weeks' gestation) delivered between 1990 and 1997. Patients with antepartum death and congenital anomalies were excluded from this study. RESULTS: The prevalence of SGA neonates among preterm deliveries was significantly higher than among term deliveries (9.3 versus 6.1%, P<0.001). The rate of induction of labor among preterm SGA deliveries was significantly higher than term SGA deliveries (17.7 versus 13.4%, P=0.002). The rates hypertensive disorders, suspected IUGR, placental abruption, cesarean section, chorioamnionitis and endometritis were significantly higher among preterm SGA than in term SGA. A multiple logistic regression analysis demonstrated that suspected IUGR, severe PIH (but not mild PIH), chronic hypertension and placental abruption were independent risk factors for induction of labor among preterm SGA neonates. In addition to these factors, oligohydramnios was considered to be an independent risk factor only among term SGA. No significant differences were found in the mean birthweight and post-partum death rates between the induced and spontaneous preterm and term SGA. The incidence of Apgar score < 7 at 5 min was significantly lower only among induced term SGA. CONCLUSIONS: Induction of labor in preterm SGA neonates is performed mainly due to maternal severe hypertension disorders. The indications for induction of labor among term SGA include maternal hypertensive disorders (mild or severe) as well as neonatal status, represented mainly by oligohydramnios. In addition, induction of labor in preterm or term SGA neonates does not change neonatal outcome. Moreover, since no evidence of improved neonatal outcome was demonstrated in either indicated group, preterm or term, the question of timing and indications for induction of labor should be discussed.

RESUMEN

OBJECTIVE: (1) To compare the preterm delivery rates in the Bedouin versus the Jewish population. (2) To compare risk factors for preterm delivery in the two populations. (3) To compare outcomes of preterm delivery between the two groups. STUDY DESIGN: 41669 Jewish singletons births of whom 2816 delivered preterm (23-36 weeks) and 26495 Bedouin singletons in whom 2064 preterm deliveries occurred, were compared. All births took place in Soroka University Medical Center. Data were obtained from the computerized database of birth discharge records. RESULTS: The incidence of preterm delivery in Bedouin women was significantly higher than the rate in Jewish women (7.8 vs. 6.8%, P<0.01). The grand multiparity rate was higher among Bedouin women (P<0.001), as was the rate of teenage (<19 years) mothers (P<0.001). Gestational diabetes, PIH, and PROM rates were higher in the Jewish population (P<0.001, P=0.017, P<0.001, respectively). A bad obstetric history and previous perinatal mortality is more common in the Bedouin population (P<0.001 for both). In a logistic regression model including all these factors, the ethnic difference in the incidence of preterm delivery remained significant. The neonatal mortality rate was higher in the Bedouin population (P<0.001), as was the rate of congenital malformations (P<0.001). The perinatal mortality of Bedouins was nearly twice that of Jewish neonates with congenital malformations. However, no difference was found when neonates without congenital malformations were compared. Congenital malformations were found to be the strongest predictor of mortality. Ethnicity per se was no longer a predictor of mortality once congenital malformations were included in a logistic regression model, but the interaction of Bedouin ethnicity and congenital malformation was a significant predictor of mortality. CONCLUSION: The incidence of preterm delivery was significantly higher in Bedouin women than in Jewish women. A full explanation for this difference was not found. However, there were significantly higher rates of congenital malformations in the Bedouin preterm delivered infants. There was a much higher rate of neonatal mortality in the Bedouin population and this ethnic difference was fully explained by the presence of congenital anomalies.

RESUMEN

OBJECTIVES: To determine the prevalence of malpresentation among preterm births and to evaluate the clinical significance of malpresentation as a predictor of neonatal complications in preterm delivery. STUDY DESIGN: A cross-sectional study was conducted comparing 692 nonvertex preterm deliveries of singleton births (24-36 weeks) to 4685 vertex preterm deliveries. Women with gestational age less than 24 weeks and birthweight <500 g were excluded from the study. RESULTS: The study population included 5377 women who met the inclusion criteria. The prevalence of malpresentation was 12.8% (692/5377); 73% in the breech presentation, 22% in the transverse lie, and 5% in other positions. The mean gestational age at birth was significantly lower in the nonvertex group (32.4+/- 3.5 vs. 34.2+/-2.6; P<0.0001). Higher rates of perinatal mortality (23.1% vs. 10.1%; P<0.0001) were observed in the nonvertex group when compared with vertex births, as well as other complications such as oligohydroamnion (9.2% vs. 3.2%; P<0.0001); small-for-gestational-age; (10.5% vs. 5.9%; P<0.001); congenital anomalies (11% vs. 5.9%; P<0.001); placental abruption (8.7% vs. 4. 1%; P<0.0001); placenta previa (6.8% vs. 2.5%; P<0.0001); premature rupture of membranes (25.4% vs. 16.6%; P<0.0001); chorioamnionitis (7.9% vs. 2.9%; P<0.001); prolapse of cord (2.3% vs. 0.6%; P<0.0001) and cesarean section rate (63.9% vs. 19.1%; P<0.0001). Neonatal mortality was found to be higher for breech presentation, odds ratio (OR)=4 (confidence interval [CI]=2.76-4; P<0.0001), transverse lie, OR=2.1 (1.1-4.12; P<0.02) and for other malpositions, OR=7.3 (2. 72-20; P<0.0001). After multivariate adjustment for birthweight, cesarean section, placental pathology and chorioamnionitis, a strong association remained between the presence of breech presentation and neonatal mortality, with an adjusted OR of 2.2 (CI=1.36-3.63; P<0.01). The adjusted OR for the two other groups of malpresentation was not statistically significant. CONCLUSION: Breech presentation in preterm delivery is an independent risk factor for neonatal mortality after simultaneous adjustment for birthweight, chorioamnionitis and placental pathology. Cesarean section was found to have a protective effect on neonatal mortality rates.

RESUMEN

OBJECTIVE: To determine the prevalence and clinical significance of meconium stained amniotic fluid (MSAF) in women with preterm delivery. STUDY DESIGN: The study population consisted of consecutive patients who arrived with intact membranes and delivered preterm, singleton neonates at the Soroka Medical Center between 1 January 1985 and 31 December 1995. Only vertex presentation was included. Antepartum death was excluded from the study. Patients were classified according to the color of amniotic fluid into two groups: MSAF and clear amniotic fluid. Maternal puerperal complications were defined in our study as the presence of at least one of the next variables: clinical chorioamnionitis; major puerperal infection including endometritis, cesarean section or postpartum hemorrhage. Perinatal complications were defined in our study as: (1) intrapartum death (IPD) or postpartum death (PPD); (2) one or more of the following: 1-min Apgar score <3, 5-min Apgar score <7 or small for gestational age. Rates of perinatal complications were assessed at: (1) 24-27 weeks; (2) 28-31 weeks; (3) 32-36 weeks. Logistic regression was used to investigate the relationship of MSAF to perinatal complications and maternal morbidity in a multivariate model. RESULTS: During the study period, a total of 96 566 deliveries occurred in our institution and 4872 (5.0%) deliveries were preterm. Among the women delivering preterm meeting eligibility criteria, 276 (5.7%) women had intrapartum MSAF. A higher rate of IPD and PPD was observed only between 32 and 36 weeks' gestation in patients with MSAF in comparison with patients with clear amniotic fluid [6.1% (14/230) vs. 2.1% (85/4045), respectively, P=0.0001]. A statistically significant higher rate of perinatal complications was found between 28 and 31 weeks' gestation, and even a higher rate was noted between 32 and 36 weeks' gestation in the MSAF group in comparison with patients with clear amniotic fluid [51% (18/35) vs. 27.2% (93/341), respectively, P=0.003; 20% (46/230) vs. 9.8% (396/4045), respectively, P=0.0004]. CONCLUSIONS: (1) MSAF is an independent risk factor for perinatal complications in preterm deliveries (OR=1.73, CI: 1.057-2.43, P=0.001; OR=2.35, CI:1.34-4.12, P=0.002, respectively). (2) MSAF was not found to be an independent risk factor for maternal morbidity.

RESUMEN

OBJECTIVE: To study the effect of indomethacin on the vasculature of isolated perfused human placental cotyledon in normal and meconium pretreated placentae. STUDY DESIGN: Isolated placental cotyledons were dually perfused and fetal perfusion pressure was used as an index of vascular resistance. Meconium-stained amniotic fluid (MSAF) was collected from patients after artificial rupture of membranes, diluted 1:2, 1:4, 1:16 and 1:32 and a spectrophotometric determination of meconium concentration in amniotic fluid was performed. Only MSAF with an optical density of 20.0 units per gram was used in this study. In five placentae, the effect of indomethacin (100 microg/ml continuous perfusion from the fetal site) on basal pressure of the fetal-placental vasculature was established. In five more placentae, the effect of indomethacin on MSAF-induced vasoconstriction was established when a bolus injections of 1 ml MSAF was made into the fetal circulation. The statistical significance of response to MSAF injection was determined by paired t-test and ANOVA repeated measurements. RESULTS: A significant vasoconstrictor response to MSAF was achieved in normal placentae. Bolus injections of MSAF into the fetal circulation resulted in a significant increase in perfusion pressure (P=0.0026). Indomethacin was capable of significantly reducing the basal perfusion pressure (P=0.03). Significant attenuation of vasoconstrictor response to MSAF occurred in the presence of indomethacin (P=0.0016). CONCLUSION: Indomethacin causes a significant reduction in basal pressure of fetal placental vasculature in the human placental circulation in vitro and is capable of attenuating the vasoconstrictory activity of MSAF. The mechanism of such activity may be explained partially by the inhibitory effect of indomethacin on the PG-mediated pathways.

RESUMEN

OBJECTIVE: To determine risk factors for maternal rehospitalization after term vaginal delivery. STUDY DESIGN: The study group consisted of all women who were rehospitalized following singleton vaginal deliveries during 1996-1998 (n = 194). The control group consisted of 427 women who were not rehospitalized during the same period. RESULTS: The incidence of rehospitalization was 0.75% (194/25885). Maternal chronic diseases, preterm contractions and pre-eclampsia rates were significantly higher among the study group as compared to the controls (25.3% vs. 8.4%, p < 0.001; 6.7% vs. 2.8%, p = 0.022; 9.3% vs. 4.9%, p = 0.037, respectively). Duration of labor was significantly longer in the study group as opposed to the controls (379 +/- 406 min vs. 259 +/- 276 min, p < 0.001). The rates of postpartum hemorrhage, blood transfusion and antibiotic treatment during delivery hospitalization were significantly higher among the study group (1.5% vs. 0.2%, p = 0.021; 4.6% vs. 0.7%, p < 0.001; 26.8% vs. 14.1%, p < 0.001, respectively). Using a forward logistic regression analysis, prolonged labor and blood transfusion during labor were found as independent risk factors associated with rehospitalization (OR 1.001, 95% CI 1.001-1.002, p = 0.001; OR 4.751, 95% CI 1.698-13.292, p = 0.003). In contrast, vertex presentation had a protective effect against rehospitalization (p = 0.027, OR 0.084, 95% CI 0.009-0.758). CONCLUSIONS: Blood transfusion and prolonged labor are independent risk factors for rehospitalization after term vaginal delivery. Special attention should be given during the early postpartum period to patients receiving blood transfusions and those with prolonged deliveries, in order to reduce rehospitalization rates.

RESUMEN

The objective of this study was to describe the frequency of occurrence of clinical mastitis in dairy herds in Ontario. The study group consisted of 65 dairy farms involved in a 2-year observational study, which included recording all clinical mastitis cases and milk sampling of quarters with clinical mastitis. Lactational incidence risks of 9.8% for abnormal milk only, 8.2% for abnormal milk with a hard or swollen udder, and 4.4% for abnormal milk plus systemic signs of illness related to mastitis were calculated for 2840 cows and heifers. Overall, 19.8% of cows experienced one or more cases of clinical mastitis during location. Teat injuries occurred in 2.1% of lactations. Standard bacteriology was performed on pretreatment milk samples from 834 cows with clinical mastitis. The bacteria isolated were Staphylococcus aureus (6.7%), Streptococcus agalactiae (0.7%), other Streptococcus spp. (14.1%), coliforms (17.2%), gram-positive bacilli (5.5%), Corynebacterium bovis (1.7%), and other Staphylococcus spp. (28.7%). There was no growth in 17.7% of samples, and 8.3% of samples were contaminated. Clinical mastitis is a common disease in dairy cows in Ontario; approximately 1 in 5 cow lactations have at lease one episode of clinical mastitis. There is, however, considerable variation in the incidence of clinical mastitis among farms. The majority of 1st cases of clinical mastitis occur early in lactation, and the risk of clinical mastitis increases with increasing parity. Environmental, contagious, and minor pathogens were all associated with cases of clinical mastitis.

RESUMEN

Brucellosis is rare in pregnancy. Recently, an increase in the incidence of this disease has been observed in our area. We present 7 cases of brucellosis in pregnancy and review the literature on the effects of brucellosis on the outcome of pregnancy. Brucellosis is rare in the Middle East and Africa and the most common source of infection is unpasteurized milk products. Brucella is a coccobacillus, gram-negative bacterium, whose hosts are mostly animals. There is controversy about the relationship between brucellosis and the outcome of pregnancy. There is some evidence that there is a higher rate of complications such as abortion, premature rupture of membranes and preterm delivery in infected animals. Reasons for this difference in the impact of brucella in animals and man include the absence of the carbohydrate erythritol in the human placenta, which appears to be a preferential medium and growth factor for brucella in the placentas of animals. There is uncertainty regarding effects of brucella in early pregnancy and no evidence of its transplacental passage in later pregnancy, causing adverse obstetrical outcome, although recently there has been a single report of Brucella abortus (biotype 2). We present 7 cases of brucellosis in pregnant women found between 1977-1988. Its incidence among the women who delivered here is 0.007% (7/92, 768 deliveries). Our first case was complicated by preterm premature rupture of membranes and preterm delivery in the 20th week of gestation. In 2 other cases there was preterm delivery with 1 developing clinical chorioamnionitis. The 4 remaining women delivered at term, although 1 had preterm premature rupture of membranes and intra-uterine growth retardation, and 2 had postpartum endometritis.

RESUMEN

Pseudotumor cerebri (PTC) is a syndrome characterized by intracranial hypertension and associated with headaches, visual disturbances and papilledema, but without any identifiable intracranial pathology. PTC during pregnancy is uncommon; we report 2 such cases. Neither patient had specific complications associated with PTC. In 1 case, US of the optic nerve was used in the management. Both delivered vaginally and each had a normal puerperium. We conclude that PTC during pregnancy has no adverse effect on outcome.
