Does vaginal bacterial colonization contribute to preterm birth in women with asymptomatic shortened cervix?

PURPOSE: The aim of this study is to describe the typical microbial spectrum and the influence of distinct vaginal infections on preterm birth in pregnancies affected by cervical incompetence. METHODS: 327 patients were admitted because of asymptomatic shortening of the cervix in the second and third trimester of pregnancy. Clinical data such as age, cervical length, gestational age at admission and at delivery and vaginal microbiologic findings were collected and analyzed. RESULTS: The spectrum of germs in the vagina revealed seven different distinct species; the most common bacteria were Ureaplasma spp. and E. coli. In 327 included patients, 217 revealed a bacterial colonization, 110 did not. Most common bacteria in women with preterm birth before 34 weeks were Ureaplasma spp., while E. coli was most common in women undergoing preterm birth after 34 weeks. Nevertheless, the rates of occurrence of these bacterial taxa were not significantly different between who underwent preterm birth to those who did not. CONCLUSIONS: This study gives an overview over the vaginal bacterial colonization in pregnant women with cervical incompetence. The clinical relevance of vaginal bacterial colonization remains unclear.

Quality of life in menopausal women in the workplace - a systematic review.

Menopausal women are a large and economically relevant group in the workforce. Yet their quality of life (QoL) and needs in the workplace have been neglected. Thus, the aim of this systematic review was to provide an overview of QoL of menopausal women in the workplace. Systematic literature searches were executed, yielding 1211 references. After abstract screening, 156 articles remained for full-text screening. Finally, 12 articles fulfilled the inclusion criteria and were included in this review. Age, educational level, type of work, working environment (e.g. crowding, confined spaces, noise, workstation design), permanent place of residency, mental factors (e.g. stress level, workload, work pattern), comorbidities, menopausal symptoms, time since menopause and physical activity have repeatedly been shown to affect QoL in the workplace in menopausal women. Low-threshold access to medical and psychological support as well as individual adaptation of the workplace environment are, among others, retrieved recommendations for employers from these findings. Further raising of awareness of special needs of menopausal working women as well as further systematic research programs are needed.

Post-traumatic stress disorder following childbirth: prevalence and associated factors-a prospective cohort study.

OBJECTIVE: Traumatic experiences during or after childbirth are subject of intense discussions in mainstream and social media as well as in scientific literature. Aim of this evaluation is to estimate the prevalence of post-traumatic stress disorder (PTSD) following childbirth in postpartum women and to evaluate the influence of maternal, obstetrical and neonatal characteristics on the degree of PTSD symptoms measured by the Impact of Events Scale questionnaire (IES-R). METHODS: In total, 589 women who gave birth in the University Medical Center Mainz, Germany in 2016, participated in a survey within the first days after birth. Of these, 278 also participated 6 months later. All participants received the validated Impact of Events Scale questionnaire (IES-R). The influence of maternal, obstetric and fetal parameters on PTSD score was evaluated. RESULTS: PTSD overall prevalence was 2.9%. Patients with PTSD had significantly less often personal support during labor (p < 0.001). Maternal age (p < 0.001), parity (p < 0.001), migration background (p < 0.001), mode of delivery (p < 0.001) and assistance during labor (p < 0.001) were parameters significantly influential on the PTSD symptom level measured by the IES-R. CONCLUSIONS: Maternal PTSD prevalence after childbirth seems to be quite rare with 2.9%. Nevertheless, recent findings assume that this prevalence may only represent the "tip of the iceberg". PTSD after childbirth should not be underestimated. As PTSD depends on personal vulnerability and existing risk factors, patients at risk have to be detected before childbirth, which appears to be challenging especially for obstetric and family care professionals.

Genetic findings in miscarriages and their relation to the number of previous miscarriages.

PURPOSE: Early pregnancy loss leads to a devastating situation for many couples. Genetic disorders found in the pregnancy tissue are a frequent cause of miscarriages. It is unclear whether maternal age or previous miscarriages are associated with a higher chromosomal anomaly rate. This study aimed to determine the cytogenetical distribution of chromosomal disorders in couples after one or more previous miscarriages as well as the influence of maternal age. METHODS: 406 fetal tissue samples obtained after spontaneous abortion between 2010 and 2014 were successfully karyotyped. This included 132 couples with at least two losses and 274 couples with sporadic miscarriage. Normal and abnormal karyotype rate was determined for age, parity, gravidity, gestational week and number of previous miscarriages by logistic regression analysis. RESULTS: 145 (35.71%) fetal tissue samples had a normal karyotype, and 261 (64.8%) did not. After adjusting for age, older patients have a statistically significantly higher probability of genetic disorders in the pregnancy tissue (p < 0.001, OR 1.064, 95% CI 1.03-1.11). With each additional year, the probability of finding chromosomal abnormalities in a miscarriage increased by 6.4%. Patients younger than 35 years have a lower probability of having chromosomal disorders in the aborted material after two or more miscarriages than after sporadic miscarriages (50.7 vs. 58.9%) (p = 0.014, OR 0.67, 95% CI 0.48-0.914). Nevertheless, the risk of embryonic chromosomal disorders in patients aged 35 and above increased from 75.5% in sporadic miscarriages to 82.4% after more than one pregnancy losses (p = 0.59, OR 1.14, 95% CI - 0.72 to 1.92). CONCLUSION: Chromosomal disorders found after one or more previous miscarriages are related to patients' age. Couples suffering two or more miscarriages should be further researched, especially in younger patients.

How common is ballooning? Hiatal area on 3D transperineal ultrasound in urogynecological patients and its association with lower urinary tract symptoms.

INTRODUCTION: Pelvic floor ultrasound plays a major role in urogynecologic diagnostics. Using 3D ultrasound we can identify integrity of levator ani and measure hiatal area in the axial plane. The main goal of our study was to measure hiatal area on Valsalva in a cohort of urogynecological patients. Furthermore, we aimed to correlate hiatal area with urogynecological symptoms, levator integrity and evaluate cut-off values for pelvic organ prolapse. MATERIALS AND METHODS: In a retrospective analysis, we included 246 patients seen for urogynecological problems in our tertiary urogynecological unit. After a standardized interview and physical examination, a 3D pelvic floor ultrasound was performed. According to the cardinal urogynecological symptoms and signs, patients were categorized into three groups: pelvic organ prolapse, stress urinary incontinence and overactive bladder symptoms. RESULTS: Median age of our study population was 66 (range 29-94) years, median parity was 2.1 (range 0-9) with 17 (6.9 %) nulliparous women. Symptoms of overactive bladder in 71.1 % were most common, followed by 54.5 % symptoms of stress incontinence and 32.1 % symptoms of prolapse. On examination 49.2 % showed signs of prolapse. Levator avulsions on 3D ultrasound were detected in 20.7 %. Hiatal area was normally distributed with a median of 28.7 cm2 (range 10.4-50.0 cm2). Patients with levator avulsion had a significantly larger hiatal area (p < 0.001). Also patients with signs of prolapse had a significantly larger hiatal area (p < 0.001). There was no correlation between hiatal area and symptoms of overactive bladder (p = 0.374). Although not reaching statistical significance there was evidence of a smaller hiatal area for patients with stress incontinence (p = 0.016). In our cohort there were 33.7 % (83) women without ballooning, 27.2 % (67) showed mild, 18.3 % (45) moderate, 12.3 % (30) marked and 8.5 % (21) severe ballooning. The ROC curve analysis for hiatal area on patients with prolapse yielded an AUC of 0.755 [95 % CI (0.696-0.814)]. Using the Youden-Index we obtained 27.53 cm2 as a cut-off with a sensitivity of 0.70 and a specificity of 0.69. DISCUSSION: Hiatal area is a new repeatable diagnostic parameter. Its clinical application could improve our understanding of the pathophysiology of pelvic organ prolapse as a form of hiatal hernia.

The influence of AMH on IVF success.

PURPOSE: Anti-Müllerian hormone has a regulative function in the activation of folliculogenesis and an influence on atresia rate. It is considered a marker for the ovarian reserve. We know that a relationship exists between AMH levels and oocyte retrieval numbers, antral follicle count, pregnancy rates and birth rates. The role of AMH as an efficient prognostic factor in determining the probability of pregnancy has been largely discussed in the literature. The aim of this study is to determine the role age and AMH levels play in success rates of IVF/ICSI therapies. To date, the sample group we examined was one of the biggest ever included in a single study of the subject. METHODS: All patients who underwent an IVF/ICSI treatment with FSH stimulation in the Wiesbaden Kinderwunschzentrum between 2003 and 2010, were no older than 44 years old, and had an evaluation of serum AMH levels before treatment were included in this study. In total, 1287 patients were analysed retrospectively. Statistical analysis was performed with SPSS. RESULTS: Females' mean age was 34.89, ranging from 21 to 44 years. The patients underwent between 1 and 11 IVF cycles. Younger women had significantly higher AMH levels (p = 0.001). Patients with higher AMH levels had significantly lower break-off rates (p < 0.0005) and a significantly higher number of oocytes retrieved (p < 0.0005). Higher levels of AMH corresponded to higher pregnancy rates (p = 0.017). AMH levels do not influence pregnancy rates in younger patients (<36 years). CONCLUSIONS: AMH is a useful parameter that should be measured before performing an IVF/ICSI treatment. In younger patients, AMH levels do not predict pregnancy outcomes. In patients older than 36 years, AMH can be used as a prognostic factor. Even when a woman's AMH levels are too low to be detected, she still an acceptable chance of becoming pregnant.

Detection of Subpubic Tumor Causing Bladder Outlet Obstruction by 3D Perineal Ultrasound.

This case report shows that 3D perineal ultrasound can be superior to clinical examination and routine 2D perineal ultrasound in the detection of an unusual subpubic tumor. A 73-year-old female patient was referred to our urogynecological outpatient unit complaining of over-active bladder symptoms and voiding dysfunction for 3 years. Gynecological examination found no signs of pelvic organ prolapse or abnormality in the vaginal cavity. Routine 2D perineal ultrasound showed substantial residual urine (ca. 300 ml on catheter) and limited bladder neck mobility, but no signs of pelvic organ prolapse. Use of standardized 3D perineal ultrasound revealed a 24 × 26 × 32 mm spherical, hypoechoic tumor below the pubic symphysis between the distal urethra and the pubic bones. This structure was mistaken for the pubic symphysis in the midline on 2D ultrasound performed earlier. At surgery, the tumor was completely excised through a vaginal incision between the urethra and the pubic symphysis. After an uneventful postoperative recovery the patient developed de-novo stress urinary incontinence, which was corrected successfully by the insertion of a retropubic tension-free suburethral sling after an interval of 8 weeks. After a further follow-up of 8 weeks the patient reported well-being, urinary continence and no voiding dysfunction; no abnormalities were found on examination. In conclusion, 3D perineal ultrasound is a useful additional tool for the diagnostic workup of bladder outlet obstruction.

Prevalence of Levator Ani Defects in Urogynecological Patients.

Introduction: Defects of the levator ani muscle complex could represent a pathophysiological link between vaginal birth trauma and urogynecological symptoms many years later. The aim of our study was to determine the prevalence of levator ani muscle defects using 3D or 4D ultrasound and palpation in urogynecological patients. Material and Methods: Urogynecological patients were retrospectively investigated using 3D or 4D ultrasound. Clinical examination consisted of palpation and 3D or 4D imaging of the levator ani muscle. Results: A total of 319 women were included in the analysis. Mean age was 64.9 years, average parity was 2.1. Stress incontinence was present in 50.8 %, overactive bladder symptoms in 69.3 % and pelvic organ prolapse in 42.3 % of patients. A levator ani defect was found on ultrasound in 76 patients (23.8 %) and on palpation in 64 women (20.0 %). In the group of patients with pelvic organ prolapse, levator ani defects were found in 32.6 % of patients using ultrasound and in 26.7 % of patients using palpation. The odds ratio (OR) for levator ani defects in women with pelvic organ prolapse was 2.3 (95 % CI [CI: confidence interval]: 1.36-3.88], p = 0.002). Conclusion: In a cohort of urogynecological patients seen at a tertiary urogynecological unit, the prevalence of levator ani defects was significantly higher in women with pelvic organ prolapse compared to women with stress incontinence or urge symptoms.

[Importance of sonography in the diagnostics of functional disorders of the female pelvic floor]. / Stellenwert der Sonographie bei der Diagnostik von Funktionsstörungen des weiblichen Beckenbodens.

Ultrasound now plays an indispensible role in urogynecological diagnostics. Sonographic imaging of the female pelvic floor allows depiction of the urethra, bladder neck, bladder, anorectum and the levator ani muscle and is currently an important clinical component for the diagnostics of functional disorders in the region of the female pelvic floor. Essential aspects in sonography of the female pelvic floor are the dynamic depiction and direct imaging of alloplastic implants. For these reasons sonographic imaging is of great clinical importance especially for the diagnostics of recurrent or postoperative complications. A further important factor which supports the success of ultrasound in the diagnostics of functional disorders of the female pelvic floor is the wide availability of ultrasound devices in patient care. Furthermore, the method is noninvasive, comparatively inexpensive and does not involve radiation.

Success Rate of Inseminations Dependent on Maternal Age? An Analysis of 4246 Insemination Cycles.

Intrauterine insemination (IUI) has latterly become less important in reproductive medicine. The aim of this retrospective analysis was to identify and evaluate the success rates of repeated insemination cycles in women of different ages. All women who underwent intrauterine insemination in the Wiesbaden Fertility Clinic between 1998 and 2010 were included in the analysis. Additional inclusion criteria were: not more than 45 years old, previous FSH stimulation and slight to moderate subfertility of the male partner. A total of 4246 insemination cycles in 1612 patients were included in the analysis. The average number of IUI cycles per patient was 2.24 (1-14). Patient age ranged from 19 to 45 years (mean: 33.9 years). Logistic regression analysis showed a drop in pregnancy rates with increasing age (p = 0.000). However, for the first three cycles the pregnancy rates for women aged 40 and 41 did not differ from those of women aged between 35 and 39 years. Overall pregnancy rates were stable in women up to the age of 40, even after several insemination cycles (7.5 and 10 %). Insemination is therefore still an effective procedure in selected patients. Stable pregnancy rates were recorded even after more than 3 cycles. After 3 cycles, the success rates for women aged 40 and 41 did not differ from those of women below the age of 40.

[Measurement of the infrapubic angle using 3D perineal ultrasound and its relationship to obstetrical parameters]. / Die Messung des infrapubischen Winkels in der 3-D-Perineal-Sonografie und seine Beziehung zu geburtshilflichen Parametern.

PURPOSE: Ultrasound has achieved an indispensable role in urogynecology. The introduction of 3 D technology has enabled sonographers to visualize structures in the axial plane. The angle of the infrapubic arc may enable us to presume the shape of the pelvis. Our aim was to describe a method for measuring the infrapubic angle and the interpubic space with 3 D perineal ultrasound through 3 D rotation, correlating them with the length of the 2nd stage of labor and the rate of levator defects. MATERIALS AND METHODS: Women after vaginal delivery were recruited and underwent a 3 D perineal ultrasound on 2nd - 3 rd day postpartum. Volume datasets were analyzed to measure the infrapubic angle and the interpubic space independently by 2 urogynecologists. The interobserver reliability and the correlation between infrapubic arc angle and the length of the 2nd stage of labor and the occurrence of levator defects were calculated. RESULTS: 110 women were enrolled. With a correlation coefficient of 0.76, the relationship between the infrapubic angle measurements of the two observers was very good. A moderate to good correlation was found for the assessment of the interpubic gap, with r = 0.69. Between the infrapubic angle and length of the 2nd stage of labor, no statistical correlation for both observer measurements (p = 0.31; p = 0.78, respectively) was found. Also the correlation between the infrapubic arc angle and the occurrence of levator avulsions was not significant (p = 0.59; p = 0.39, respectively). CONCLUSION: 3 D ultrasound technology enables us to identify and evaluate the interpubic gap and the infrapubic arc with a high inter-observer reproducibility. However, from our data, the infrapubic angle does not seem to influence the length of the 2nd stage of labor and the occurrence of levator defects.

Patient goals after incontinence procedures: does the single-incision sling satisfy them?

OBJECTIVE: This study was undertaken to describe short-term postoperative achievement of subjective preoperative goals for single-incision MiniArc slings, in comparison with tension-free vaginal tape (TVT). METHOD: Patients submitted to mid-urethral sling (TVT and MiniArc) procedures for stress urinary incontinence (SUI) in two centers were included in this prospective study. Before surgery, the patients completed a preoperative open-ended questionnaire, in which they described their personal outcomes goals for SUI surgery and the degree of severity of their symptoms. At the first postoperative check, they were asked to assess the degree to which their goals had been met and the degree of postoperative incontinence symptoms; their grade of satisfaction was evaluated with IIQ-7, UDI-6 and a 0-10 visual analog scale. RESULTS: One hundred and eight patients (TVT n=51, MiniArc n=57) were included in this study. Incontinence symptom relief and improvement of quality of life were the most commonly described preoperative goals. Six to eight weeks after surgery, 47 patients (92.1%) after TVT and 53 (92.9%) women after single-incision slings were objectively cured (P=1). After surgery, more than 90% of the patients in both groups achieved their preoperative goals. Symptom scores improved significantly and were comparable in both groups. CONCLUSION: Our results show that self-reported achievement of preoperative goals of patients submitted to single-incision slings are comparable at the first follow-up with patients who have undergone the classic mid-urethral sling.

Impact of mode of delivery on levator morphology: a prospective observational study with three-dimensional ultrasound early in the postpartum period.

OBJECTIVE: To evaluate morphology and integrity of the levator ani muscle (LAM) with three-dimensional ultrasound early in the postpartum period. DESIGN: Prospective cross-sectional observational study. SETTING: University hospital in Germany. POPULATION: Women after vaginal delivery and caesarean section with no previous vaginal delivery. METHODS: Three-dimensional perineal ultrasound was performed between 48 and 72 hours postpartum. The axial plane at the level of minimal hiatal dimension and tomographic ultrasound imaging were used to determine LAM biometry and defect. MAIN OUTCOME MEASURES: Primary outcome was to compare hiatal dimensions and levator defect following vaginal delivery or caesarean section. For secondary outcomes, we evaluated the role of caesarean section in protecting levator integrity, and the possible involvement of the first stage of labour in LAM changes. RESULTS: In all, 157 women participated: 81 (51.6%) following vaginal delivery (70 spontaneous and 11 operative deliveries) and 76 (48.4%) following caesarean section (55 elective and 21 emergency caesarean sections). All biometric indices of the levator were higher after vaginal delivery (P<0.001), except for LAM thickness. LAM defects were found to be significantly associated with vaginal delivery, with relative risk 7.5 (P<0.001). Following vaginal delivery, 32 (39.5%) levator defects were found: 27 (38.5%) after spontaneous delivery and five (45.4%) after operative delivery. Four (5.2%) women had a levator defect following emergency caesarean section. CONCLUSION: Vaginal delivery modifies and damages the LAM: the risk of levator defect after vaginal delivery is more than seven times higher than after caesarean section. Despite this, emergency caesarean section seems to have no complete preventive effect on LAM trauma.

Single-Incision Slings (SIS) - a New Option for the Surgical Treatment of Female Stress Urinary Incontinence.

The new development of single-incision slings (SIS) for the treatment of female stress urinary incontinence offers comparable results with only minimal side effects and will find wide acceptance in modern incontinence surgery. This mini-sling is inserted over a single vaginal incision and fixed on both sides to the pelvic wall tissue with special anchors, without passing through the groin and avoiding a blind tape passage. Compared with the established sub-urethral tapes, there are comparable success rates with fewer complications. Randomised prospective studies are needed to evaluate whether, in the long run, the benefits of the single incision technique can be correlated with satisfying continence results.

[Clinical and economic challenges of moderate preterm babies born between 32+0 and 36+6 weeks of gestation]. / Klinische und ökonomische Herausforderung der moderaten Frühgeburt zwischen 32+0 und 36+6 SSW.

BACKGROUND: Preterm births show a worldwide increasing incidence. The majority of preterm births occur between 32+0 and 36+6 weeks of gestation and are associated with an increased rate of maternal and neonatal morbidity. The focus of our research is the clinical and economical analysis of all preterm births between 32+0 and 36+6 weeks of gestation in a German level 1 perinatal centre over a period of 3 years. MATERIALS AND METHODS: A retrospective analysis of all preterm births between 32+0 and 36+6 weeks of gestation in the University Hospital Mainz from 2007 to 2009 was undertaken. Data were collected using our electronic documentation system. Gestational age at delivery, mode of birth, indication for delivery, duration of the peripartum treatment, treatment of the newborn in the children's hospital, birth weight and therapy costs were evaluated. RESULTS: We recorded 407 moderate preterm births in total; this amounts to a rate of of 10% of all births. Major causes of prematurity were PPROM, preterm labour and preeclampsia/HELLP. Maternal and fetal systemic diseases were more uncommon. Rates of Caesarean sections (62%) and of neonatal inpatient treatment needs (58.5%) were high. Maternal treatment costs were 332 Euro/day. The mean duration of maternal inpatient treatment was 13.15 days. DISCUSSION: Moderate preterm birth is associated with maternal morbidity frequently due to a high rate of Caesarean sections. Neonatal morbidity is also increased. In comparison with previous research, we saw an increased rate of pregnancy complications. This could be typical for a level 1 perinatal centre. Moderate preterm birth is seen as the cause of considerable treatment costs.

The IUGA/ICS classification of complications of prosthesis and graft insertion: a comparative experience in incontinence and prolapse surgery.

INTRODUCTION AND HYPOTHESIS: This is a presentation of case series after the use of alloplasic material in urogynaecology. METHODS: From 2004 to 2010, a total 179 patients with complications have been referred directly after the use of alloplastic material in incontinence and prolapse surgery. Of this total, 125 patients had a previous vaginal sling plasty because of urinary stress incontinence, while 54 patients underwent a prolapse surgery with mesh use. Symptoms and findings are expressed by the recently introduced International Urogynecological Association/International Continence Society (IUGA/ICS) terminology. RESULTS: The most frequent findings after vaginal sling plasty were bladder outlet obstruction, pain and tape exposure. The most frequent findings after prolapse surgery were pain and mesh erosion. The IUGA/ICS classification does not give the possibility to express functional disorders. Most revisions were done more than 2 months after surgery. After incontinence surgery, mostly the vaginal area of suture line was affected; after prolapse surgery, the vagina and the trocar passage were affected. CONCLUSIONS: Mesh complication and affected site after prolapse surgery do differ from those after incontinence surgery. The IUGA/ICS classification of mesh complication facilitates the comparison of mesh complication.

["War of the slings": when do I do what and which concept will endure?]. / Krieg der Bänder : Wann mache ich was und welches Konzept hat Bestand?

The number of incontinence surgeries has drastically increased for female stress urinary incontinence requiring treatment. On the one hand, public perception of the problem has become widespread, increasingly removing the stigma of the condition, and on the other hand, newer surgical techniques and materials have been continually developed in the last 15 years. The use of tension-free vaginal slings for the treatment of stress incontinence is associated with high continence rates and minimal side effects and has meanwhile become the gold standard in the management of incontinence.

A new algorithm for improving fetal weight estimation from ultrasound data at term.

OBJECTIVE: The purpose of this retrospective study was to find a method of improving the accuracy of fetal birth weight estimation on the basis of traditional ultrasonographic measurements of the head, thorax, and femur at term. In this context, we analyzed a novel regression method comparing to existing algorithms. METHODS: The delivery records of two hospitals were searched for women who delivered macrosomic infants, and the patients' medical records were retrospectively reviewed in order to derive clinical and ultrasonographic data at term. A total of 223 patients with macrosomic infants (birth weight > 4,000 g) were identified. These patients were complemented by data for 212 women who had ultrasound fetal assessments of less than 4,000 g. We used the method of isotonic regression to construct a birth weight prediction function that increases monotonically with each of the input variables and which minimizes the empirical quadratic loss. RESULTS: A suspicion of macrosomia was based on a history of macrosomia, fundal height, and sonographic weight estimation >4,000 g. The mean period between ultrasound weight estimation and delivery was 7.2 days. The ability of the biometric algorithms developed to predict fetal weight at term ranged between a mean absolute error of 312 and 344 g, given a confidence interval of 95%. We demonstrate that predictions of birth weight on the basis of ultrasound data can be improved significantly, if an isotonic regression model is used instead of a linear regression model. CONCLUSIONS: This study demonstrates that ultrasound detection of macrosomia can be improved using the isotonic regression method.

Pregnancy outcome in maternal Crigler-Najjar syndrome type II: a case report and systematic review of the literature.

OBJECTIVE: To report a case of maternal Crigler-Najjar syndrome (CNS) type II in pregnancy, systematically review the literature for similar case reports, and to evaluate whether pregnancy is safe in patients with the disease. Data sources included the PubMed and up to date databases. RESULTS: A 37-year-old mother with CNS type II was treated with phenobarbital during her pregnancy and her bilirubin levels were monitored. Her newborn had mild direct hyperbilirubinemia, did not require any treatment and his postnatal follow-up showed normal growth and development as well as normal hearing. CONCLUSION: CNS type II is rare, and only a few pregnancies with this condition have been reported. Maternal treatment with phenobarbital lowers the unconjugated bilirubin and avoids fetal and newborn sequelae.

The influence of macrosomia on the duration of labor, the mode of delivery and intrapartum complications.

OBJECTIVE: This study assessed the perinatal outcome in a series of macrosomic fetuses with mothers from a general obstetric population in whom vaginal delivery was planned. METHODS: In all, 215 women with macrosomic infants were included from a total of 2,622 deliveries. The pattern of maternal weight gain in pregnancy, the influence of fetal macrosomia on the duration of labor and the delivery outcome were investigated in this group. The main issues studied were the impact of fetal weight on the mode of delivery, the duration of the two stages of delivery and the incidence of intrapartum complications in fetuses larger than 4,000 g in comparison with normal-weight fetuses. RESULTS: Complete data were obtained for 594 patients, including 215 macrosomic infants and 379 randomly assessed normal-weight infants. With regard to the mode of delivery, a direct correlation was observed between maternal weight gain and the incidence of secondary cesarean section (P<0.014) when vaginal delivery was initially planned. There was also a direct correlation between increasing birth weight and a higher incidence of secondary cesarean section and assisted vaginal delivery (P<0.002). In the first stage of labor, there was a statistically significant difference for obstructed labor between the two groups (P<0.03). The rate of perineal injuries and the incidence of postpartum hemorrhage were similar in the two groups. CONCLUSIONS: As some of the risk factors identified are known prior to delivery, every woman in whom there is a suspicion that the fetus may weigh up to 4,500 g should receive individual guidance regarding special intrapartum and perinatal conditions.
