Attention deficit and learning disabilities (ADHD/LD) among high school pupils in Holon (Israel).

Five hundred forty-three students participated in the study. The prevalence of ADHD according to criteria of DSM-4 among them was 15.2%, including three subgroups: ADHD (inattentive)- 9.7%, combined- 4.5%, and ADHD-hyperactivity-impulsivity (HI)- 1%. The prevalence of learning disability (LD) was 17.6%. The gender ratio in both groups (ADHD and LD) was equal. These pupils had lower academic achievements with lower marks. The prevalence of ADHD/LD found in the present study in Israel is in a higher range of those reported in the literature. We should remember that ADHD/LD is a neuro-behavioral disability and these children and adolescents need an early educational correcting program at home and at school.

Attention deficit and hyperactivity disorder (ADHD) and learning disabilities (LD): adolescents perspective.

Three hundred and eight pupils in the age group 12-18 years were interviewed and examined. They had been diagnosed as having attention deficit and hyperactivity disorder (ADHD) and learning disabilities (LD), and were attending a high school devoted to special education. Their classification into subgroups was as follows: ADHD - inattentive (I) = 22.1%, ADHD - hyperactivity/impulsivity (HI) = 12.3% and combined = 42.2%. Only 25% of them were treated by methylphenidate (Ritalin). Ninety-four percent of them were diagnosed with comorbidity of 'learning disabilities'. Thirty-four percent of them reported being severely stressed when going to school and sitting in class. Their complaints were: tiredness and excessive needs to sleep, frequent quarrelling with close friends, feeling different from other classmates and having low self-esteem (SE). They complaint that their parents don't understand them. Things that irritated them the most were being lied to and coercion by others. The authors suggest to consider ADHD/LD as neurobehavioral disability. It is mandatory to prepare them for adult life with proper social skills and a suitable occupation.

Auditory hallucinations in acute stroke.

Auditory hallucinations are uncommon phenomena which can be directly caused by acute stroke, mostly described after lesions of the brain stem, very rarely reported after cortical strokes. The purpose of this study is to determine the frequency of this phenomenon. In a cross sectional study, 641 stroke patients were followed in the period between 1996-2000. Each patient underwent comprehensive investigation and follow-up. Four patients were found to have post cortical stroke auditory hallucinations. All of them occurred after an ischemic lesion of the right temporal lobe. After no more than four months, all patients were symptom-free and without therapy. The fact the auditory hallucinations may be of cortical origin must be taken into consideration in the treatment of stroke patients. The phenomenon may be completely reversible after a couple of months.

Is age of onset of Crohn's disease governed by mutations in NOD2/caspase recruitment domains 15 and Toll-like receptor 4? Evaluation of a pediatric cohort.

Crohn's disease (CD) is caused by a combination of environmental and genetic factors. It is not clear at present whether age of onset (AOO) is a random event or dictated by genotype or environmental factors. Mutations in the NOD2/caspase recruitment domains 15 (CARD15) and in the Toll-like receptor 4 (TLR4) gene have been associated with increased susceptibility for CD. We sought to determine whether single or multiple mutations in these genes are linked to earlier susceptibility for CD. A cohort of 189 patients with CD (82 pediatric onset, 107 adult onset) were genotyped for three disease-associated single-nucleotide polymorphisms (SNPs), one haplotype association (JW1-SNP5), and one background polymorphism (P268S) of the NOD2/CARD15 gene and for two SNPs of TLR4. Analysis of heterozygosity, homozygosity, alleles, and haplotypes of cohort on age or pediatric onset was performed. AOO ranged from 8 mo to 68 y. The presence of the three NOD2/CARD15 and two TLR4 mutations, the NOD2/CARD15 JW haplotype, compound heterozygosity, and homozygosity were not associated with AOO. Presence of P268S in the absence of known NOD2/CARD15 mutations was correlated with increasing age and adult onset of CD, whereas pediatric-onset disease was associated with male gender and the wild-type NOD2/CARD15 haplotype. Mutations in NOD2/CARD15 and TLR4 are not significantly associated with AOO in our population. Mutations that are not in linkage disequilibrium with the background mutation P268S of the NOD2/CARD15 gene probably play a more significant role in pediatric-onset disease.

Remifentanil: a novel systemic analgesic for labor pain.

In a double-blind, randomized, controlled clinical trial, we compared the analgesic effect of remifentanil in patient-controlled IV analgesia (PCIA) during labor and delivery with the effect of an IV infusion of meperidine. Eighty-eight healthy term parturients who requested IV analgesia for labor pain were enrolled in the study and were randomly assigned to receive either increasing doses (0.27-0.93 microg/kg per bolus) of PCIA remifentanil (n=43) or an IV infusion of meperidine 150 mg (range, 75-200 mg) per patient (n=45). Remifentanil by the PCIA device was more effective and reliable analgesia for labor and delivery than IV infusion of meperidine. The visual analog score was lower (35.8 +/- 10.2 versus 58.8 +/- 12.8; P <0.001) and the patient satisfaction score higher (3.9 +/- 0.6 versus 1.9 +/- 0.4; P <0.001), with less of a sedative effect (1.2 +/- 0.1 versus 2.9 +/- 0.1; P <0.001) and less hemoglobin desaturation (97.5% +/- 1.0 versus 94.2% +/- 1.5; P <0.007). The percentage of analgesia failure (the rate of crossover from opiate to epidural analgesia) was less for remifentanil compared with meperidine (10.8% versus 38.8%; P <0.007). There were no significant differences between groups in the mode of delivery or neonatal outcome. There were fewer nonreassuring abnormal fetal heart rate patterns, i.e., higher variability and reactivity with fewer decelerations, under remifentanil therapy as compared with meperidine (P <0.001). In conclusion, an intermittent incremental regimen with repeated small-dose PCIA boluses of remifentanil provided effective and reliable analgesia during labor and delivery.

p27kip1 expression is inversely related to the grade of gastric MALT lymphoma.

BACKGROUND: Decreased or lost expression of the cyclin-dependent kinase inhibitor p27kip1 protein has been found to be a poor prognostic factor in many cancers, including gastric cancer. AIM: To evaluate p27kip1 expression in gastric mucosa-associated lymphoid tissue (MALT) and gastric B-cell lymphoma. METHODS: Fifty-two cases of gastric lymphoma, mean age 68.7 yr (range 23-90 yr), 11 of chronic Helicobacter pylori-associated gastritis, and 5 of normal gastric mucosa were studied. Patients were classified into two groups. Stage IE gastric lymphomas were defined as local gastric lymphoma of MALT and more advanced stages as advanced gastric lymphoma. Twenty-three patients diagnosed as stage IE, 13 of these were low-grade and 10 diffuse large B-cell lymphoma (DLBL). Twenty-nine patients were at stage IIE or above, 18 with low-grade and 11 with DLBL. Serial sections were evaluated by immunohistochemistry after staining with antibodies against p27/Kip1 and Ki-67. RESULTS: The proliferative index was higher in gastric DLBL than in low-grade MALT lymphomas, 57.1+/-31.2 vs 17.3+/-20.6 (p=0.0001). The mean p27kip1 expression score for high-grade patients was significantly lower compared with that of low-grade patients, 0.5+/-0.4 and 1.6+/-0.8, respectively (p=0.001). Comparative evaluation of p27kip1 expression in malignant lymphoid cells revealed that B cells of the localized gastric DLBL patients expressed the least p27kip1, 0.36+/-0.32. This value was lower than that of malignant lymphoid cells of patients with advanced DLBL, 0.64+/-0.53, advanced low-grade MALT lymphoma, 1.59+/-0.79, and localized low-grade MALT lymphoma, 1.59+/-0.84. In the multivariate model in which all p27kip1 variables were entered, the expression of p27kip1 in malignant lymphoid cells was inversely correlated with the grade of the lymphoma irrespective of the stage of the disease (p=0.0001), and significantly predicted grade: OR:0.07, 95% CI 0.07-0.31, p=0.0001. CONCLUSION: p27kip1 may be a putative distinct molecular marker to differentiate between low-grade and high-grade gastric lymphoma.

Antihypertensive effect of low calcium dialysis.

BACKGROUND: During maintenance hemodialysis acute elevation in serum calcium is common. Low calcium dialysis is advocated as a therapy for prevention of dialysis-induced hypercalcemia. Approximately 16% of our chronic hemodialysis patients experience elevated arterial blood pressure during the hemodialysis session, becoming hypertensive by the end of the treatment. All these patients exhibited post-dialysis hypercalcemia. OBJECTIVES: To investigate the effect of low calcium dialysis on post-dialysis hypertension in view of an evident link between serum calcium and blood pressure in both normal renal function and chronic renal failure patients. METHODS: We evaluated 19 chronic hemodialysis patients in whom both post-dialysis hypertension and PDHCa were observed. We investigated changes in serum total calcium, ionized calcium, intact parathormone levels and arterial blood pressure in response to 4 weeks low calcium dialysis as a treatment for PDHCa. RESULTS: When PDHT patients were treated with low calcium dialysis, post-dialysis blood pressure was significantly decreased compared to pre-dialysis values (155.3 +/- 9.7/82.2 +/- 7.9 mmHg pre-dialysis vs. 134.1 +/- 20.8/80 +/- 8.6 mmHg post-dialysis, P = 0.001). Additionally, post-dialysis blood pressure was significantly lower than post-dialysis blood pressure prior to the low calcium dialysis treatment (176.1 +/- 15/86 +/- 10.8 mmHg post-standard dialysis, 134.1 +/- 20.8/80 +/- 8.6 mmHg after low calcium dialysis, P = 0.001). A decline in post-dialysis serum calcium (2.34 +/- 0.2 vs. 2.86 +/- 0.12 mmol/L, P= 0.04) and ionized calcium (1.17 +/- 0.12 vs. 1.3 +/- 0.06 mmol/L, P = 0.03) compared to pre-dialysis levels was also achieved by this treatment, with no significant changes in iPTH levels. CONCLUSIONS: These data suggest a role for low calcium dialysis in treating acute serum calcium elevation and post-dialysis hypertension in patients receiving maintenance hemodialysis.

Using anovaginal distance at the beginning of labor to predict the likelihood of instrumental delivery.

OBJECTIVE: To investigate whether anovaginal distance in parturients has an impact on the instrumental delivery rate. STUDY DESIGN: In this study with prospective data collection and a convenience sample, 400 parturients planning for vaginal delivery at term with a singleton fetus in vertex presentation were enrolled. Anovaginal distance was measured in the lithotomy position during the latent phase of labor or early first stage. This distance is thought to reflect the angle of inclination of the birth canal axis. RESULTS: At the cutoff point of 25 mm for anovaginal distance, the odds ratio for instrumental delivery was 2.5 (95% CI 1.48-6.6, p<0.05). A final model of instrumental delivery, controlling for various confounding variables, correctly predicted 91.38% of the instrumental deliveries (p<0.0001). The variables anovaginal distance >25 mm (OR 2.9, 95% CI 1.2-6.7, p=0.01), parity (OR 0.54, 95% CI 0.29-0.99, p=0.046) and duration of second stage of labor (OR 1.01, 95% CI 1.004-1.01, p=0.001) significantly contributed to the prediction of instrumental delivery after controlling for the other parameters. CONCLUSION: Women with an anovaginal distance of >25 mm at the beginning of labor was 2.5 more likely to undergo instrumental delivery than were women with an anovaginal distance of <25 mm.

Patient-controlled epidural analgesia for labor pain: effect on labor, delivery and neonatal outcome of 0.125% bupivacaine vs 0.2% ropivacaine.

The objective was to evaluate the influence of patient-controlled epidural analgesia (PCEA) using low doses of bupivacaine vs. ropivacaine, on labor pain, motor blockade, progression of labor, delivery and neonatal outcome. This randomized double blind study included 565 parturients. All received a 5-mL/h infusion and PCEA (5-mL boluses with a 20-min lockout, maximum volume 20 mL/h) of either 0.125% bupivacaine (n = 313: 165 nulliparous, 148 parous) or 0.2% ropivacaine (n = 252: 113 nulliparous, 139 parous). Pain score, lower limb motor block, sensory levels, local analgesic doses required, hemodynamic parameters, side effects and complications were assessed. Obstetric variables included cervical dilation at epidural insertion, incidence of ruptured membranes and their duration, use of oxytocin, fetal heart rate changes, duration of labor, mode and outcome of delivery, and use of invasive and non-invasive fetal monitoring. Neonatal characteristics included birth weight, Apgar scores, umbilical artery pH, serum bilirubin, hypoglycemia, need for assisted ventilation, sepsis or sepsis study, feeding difficulties and respiratory distress syndrome. Ropivacaine 0.2% was equianalgesic with 0.125% bupivacaine, but produced less motor block (P < 0.0001). There were no significant differences, however, in duration of labor, delivery type or neonatal outcome.

Esophageal pH study and symptomatology of gastroesophageal reflux in newborn infants.

A retrospective study was undertaken to assess the association between esophageal pH monitoring variables and signs such as regurgitation, vomiting, apnea, bradycardia, and cyanotic episodes attributable to gastroesophageal reflux (GER) in neonates. One hundred thirty-four infants with one or more of the above-described signs underwent 24-hour distal esophageal pH monitoring in the neonatal intensive care unit, and were divided into 2 groups by gestational age. Group 1 (preterm infant group) consisted of infants aged 25 to 36 weeks of gestation ( n = 45) and group 2 (term infant group) consisted of infants aged 37 to 42 weeks gestation ( n = 89). Esophageal pH monitoring variables were compared by gestational age group and within preterm infants by theophylline treatment and, separately, by nasogastric tube using the Mann-Whitney U test. Comparisons of nominal data were made using the chi square test. Logistic regression analysis was used to assess the net effect of each independent variable on the risk of developing GER. The prevalence of GER was not influenced by gestational age. The prevalence of gastrointestinal signs did not differ between groups. Cardiorespiratory signs attributed to GER were more frequent in preterm infants than in term infants. The number of episodes with pH < 4 in 24 hours was greater in the term compared with the preterm infant groups. Logistic regression analysis failed to detect an association between acid GER and gestational age, apnea, bradycardia, cyanotic episodes, vomiting, or regurgitation. Theophylline treatment and the presence of a nasogastric tube did not significantly affect the esophageal pH monitoring variables in preterm infants. Preterm infants have a smaller number of reflux episodes compared with term infants. In addition, treatment with theophylline for apnea of prematurity and the presence of a nasogastric tube in preterm infants did not significantly affect pH-monitoring variables in preterm infants.

Application of Maastricht 2-2000 guidelines for the management of Helicobacter pylori among specialists and primary care physicians in israel: are we missing the malignant potential of Helicobacter pylori?

BACKGROUND: The Maastricht 2-2000 guidelines on the current management of Helicobacter pylori infection were recently adopted by the Israeli Gastroenterological Association. GOAL: To determine the impact of these clinical guidelines on the current knowledge, attitudes, and management of H. pylori among primary care physicians, hospital internists, and gastroenterologists in Israel. STUDY: Self-administered, voluntary, anonymous questionnaires were given personally to 229 physicians, 73 primary care physicians, 71 internists, and 85 gastroenterologists. The questions evaluated 4 main issues in the management of H. pylori: (1). the optimal diagnostic test, (2). indications for eradication, (3). combination and duration of triple therapy, and (4). the need for confirmation following eradication. RESULTS: There were significant variations in the adherence of those recommendations among gastroenterologists, internists, and primary care physicians. Specifically, 94.1% of gastroenterologists and 88.9% of internists consider the urea breath test the test of choice for H. pylori diagnosis compared with 60.0% of the primary care physicians. Significant differences in the eradication indications for mucosa-associated lymphoid tissue (MALT) lymphoma, first-degree relatives of gastric cancer patients, atrophic gastritis, functional dyspepsia, and concomitant use of nonsteroidal antiinflammatory drugs were demonstrated among gastroenterologists and the other groups. CONCLUSIONS: Primary care physicians may not be aware of important indications for diagnosis and eradication of H. pylori related to the risk of gastric malignancy or concomitant use of nonsteroidal antiinflammatory drugs. Public health agencies may need to increase penetration of the Maastricht 2000 recommendations to primary care physicians.

Improved immunogenicity of a novel third-generation recombinant hepatitis B vaccine in patients with end-stage renal disease.

Hepatitis B (HBV) infection remains a significant epidemiological problem in the end-stage renal disease (ESRD) population. Vaccination programs using second-generation vaccines lead to effective seroprotection in only 50-60% of these patients. The purpose of this case series was to describe our experience with a novel third-generation vaccine, Bio-Hep-B, in ESRD patients who had not developed protective anti-HBs titers following a second-generation HBV vaccination protocol. Twenty-nine ESRD patients who had not responded in the past to a standard second-generation HBV vaccination protocol were included in this series. Each patient received 10 microg of Bio-Hep-B) intramuscularly at 0, 1 and 6 months. A month after completion of the vaccination protocol, anti-HBs antibody levels were measured. Following immunization, 25 of 29 patients (86%) developed seroprotective anti-HBs levels > or =10 mIU/ml. There was a significant difference in the titers of anti-HBs antibodies prior to and following vaccination (p < 0.0001). Statistical analysis of the variables age, gender, diagnosis, dialysis mode, weight, hemoglobin, albumin, and KT/V failed to detect predictors of antibody response. A retrospective analysis of the results of a second-generation vaccination program for the years 1999-2001 in our department showed that 19 of 36 (56.4%) ESRD patients developed seroprotection. In conclusion, the results of this study show that the third-generation HBV vaccine Bio-Hep-B is highly immunogenic in the population of ESRD patients who did not respond in the past to a second-generation vaccine. This enhanced seroprotection offers hope that the new vaccine will reduce the rate of non-responders and help to eliminate HBV infection from dialysis centers.

Identification of the epidural space: loss of resistance with air, lidocaine, or the combination of air and lidocaine.

The ideal technique for identifying the epidural space remains unclear. Five-hundred-forty-seven women in labor who requested epidural analgesia were randomly allocated to three groups according to the technique by which the epidural space was identified: 1) loss-of-resistance with air (air; n = 180), 2) loss-of-resistance with lidocaine (lidocaine; n = 185), and 3) loss-of-resistance with both air and lidocaine (air-plus-lidocaine; n = 182). We assessed ease of epidural catheter insertion, characteristics of the blockade, quality of analgesia, and complications. The inability to thread the epidural catheter occurred in 16% of the air, 4% of the lidocaine, and 3% of the air-plus-lidocaine patients (P < 0.001). More patients from the air group had unblocked segments (6.6% versus 3.2% and 2.2%, respectively; P < 0.02). The incidence of accidental dural puncture was greater in the air group (1.7% versus 0% in the other two groups; P < 0.02). Pain scores, time to onset of analgesia, upper sensory level, motor blockade, and the incidence of hypotension, transient neurological deficits, postpartum urinary retention, and postdural puncture headache were comparable. Identification of the epidural space with air was more difficult and caused more dural punctures than with lidocaine or air plus lidocaine. Additionally, sequential use of air and lidocaine had no advantage over lidocaine alone.

Influence of Helicobacter pylori eradication on gastroesophageal reflux symptoms and epigastric pain in children and adolescents.

OBJECTIVE: Conflicting reports have noted a possible association linking eradication of Helicobacter pylori with aggravation of gastroesophageal reflux (GER) disease. We prospectively evaluated the effect of eradication of H pylori on GER symptoms and epigastric pain and the association among these 3 parameters in a pediatric cohort. METHODS: Patients who were referred for gastroscopy were evaluated for frequency, severity, and nocturnal presence of symptoms related to GER as well as epigastric pain. Patients who were positive for H pylori received triple antibiotic therapy. The patients were followed for at least 6 months after therapy. Patients with successful eradication had symptoms compared with their pre-eradication state and were compared with a cohort of patients without H pylori or those with persistent H pylori. RESULTS: Of 119 children and adolescents who were recruited, 95 patients completed the study, with a mean follow-up of 11.2 months. The distribution of outcomes for each GER symptom (better, worse, unchanged) was similar before and after eradication and did not depend on prior H pylori status. Among patients with GER and epigastric pain, improvement in epigastric pain was significantly correlated with the improvement in GER symptoms but not with eradication of H pylori. CONCLUSIONS: Eradication of H pylori is not associated with increased symptoms of GER in children and adolescents. Improvement in epigastric pain in children is significantly correlated with the improvement in GER symptoms but not with eradication of H pylori.

Pediatric Crohn's disease and growth retardation: the role of genotype, phenotype, and disease severity.

BACKGROUND: Delayed growth is a well-established feature of pediatric Crohn's disease. Several factors have been shown to affect growth, including disease location, severity, and treatment. The recently discovered NOD2 gene has been correlated to ileal location of Crohn's disease and subsequently could affect growth through the resulting phenotype or as an independent risk factor. The aim of our study was to determine if growth retardation is affected by genotype independently of disease location or severity. METHODS: Genotyping for 3 NOD2 single-nucleotide polymorphisms was performed in 93 patients with detailed growth records. Parameters including disease location, disease severity, and NOD 2 genotype and their effect on z scores for height and weight at disease onset and during follow-up were analyzed. RESULTS: NOD2 mutations were correlated with ileal location but not with disease severity or growth retardation. Ileal involvement was significantly associated with height retardation at disease onset and the lowest z score during follow-up. Use of steroids affected weight but not height. Regression models for growth variables revealed that the strongest association with impaired growth is with disease severity (weight- and height-failure odds ratios: 6.17 and 4.52, respectively). CONCLUSIONS: Severity of disease is correlated with growth failure for both height and weight. Location of disease is a weaker predictor of disordered growth and is correlated with growth retardation but not growth failure. The NOD2 genotype was not correlated with growth retardation or growth failure.

Vacuum application through a nonfully dilated cervix: a viable option.

The aim of this cross-sectional study was to assess the feasibility of vacuum delivery through a nonfully dilated cervix. The study group consisted of 39 women with vacuum deliveries through a nonfully dilated cervix larger than 9 cm and station of the head at S or more +2 cm. These were compared to a control group of 215 vacuum deliveries at a fully dilated cervix and 46 women who underwent cesarean section at a nonfully dilated cervix larger than 9 cm. The main indication for vacuum extraction in the study group was fetal distress and in the control groups prolonged 2nd stage, dysfunctional labor and fetal distress. Maternal and neonatal morbidity was low and not different between the groups. Neonatal well being, evaluated by cord pH and 5-min Apgar score, was not different. Based on predefined criteria, vacuum extraction through a nonfully dilated cervix is a viable alternative to emergency cesarean section and is apparently not associated with higher maternal or infant morbidity.

Positive serology for Helicobacter pylori and vomiting in the pregnancy.

INTRODUCTION: Recently, several investigators have suggested that H. pylori may be a contributory factor in hyperemesis gravidarum. The purpose of this study was to evaluate whether seropositivity for IgG antibodies to H. pylori may also be related to nausea, vomiting, heartburn and epigastric pain in pregnancy. MATERIALS AND METHODS: One hundred and eighty-five women, at term pregnancy, were included in the study. All women completed a questionnaire regarding information on the number of pregnancies and deliveries, weight gain, smoking and gastrointestinal complaints before and during pregnancy. The presence of H. pylori infection was determined by serology. RESULTS: The overall prevalence rate of H. pylori seropositivity was 45.9%. Women positive for H. pylori IgG were older (28.7+/-4.5 vs. 27.0+/-4.5, p=0.02), had more prior pregnancies (3.2+/-2.1 vs. 2.6+/-1.6, p=0.02) and deliveries (2.6+/-1.6 vs. 2.0+/-1.1, p=0.006) and reported vomiting in the first trimester more frequently than H. pylori negative patients (81.2% vs. 65%, p=0.004). On the other hand vomiting in the second trimester was reported more frequently among smokers during pregnancy compared to non-smokers. CONCLUSIONS: H. pylori seropositivity is significantly associated with emesis gravidarum but not with gastro-intestinal symptoms later in pregnancy. First trimester vomiting more than doubles the likelihood that the gravida is H. pylori IgG positive.

What to do after a failed attempt of vacuum delivery?

OBJECTIVES: To determine whether there is a difference in maternal and neonatal outcomes if a sequential operative vaginal or cesarean delivery follows failed vacuum delivery. STUDY DESIGN: A cross sectional study. We have analyzed maternal and neonatal outcomes of 215 vacuum extractions (group 1), 106 forceps assisted deliveries (group 2), 28 deliveries in which failed vacuum extraction were followed by forceps delivery (group 3) and 22 deliveries in which failed vacuum extraction were followed by cesarean delivery (group 4). RESULTS: Compared to other groups, patients in group 4 had significantly more post partum anemia, meconium stained amniotic fluid and hospital stay (both maternal and neonatal) as well as lower pH. Apgar scores were similar in groups 3 and 4. Incidence of respiratory distress syndrome, cephalhematoma and jaundice were similar in neonates of all groups. CONCLUSIONS: If an attempted vacuum delivery has failed, the risk of adverse neonatal outcome is increased with either subsequent forceps or cesarean delivery. It should remain in the judgment of the attending obstetrician to choose the method most suitable under the given circumstances.
