Abstract
OBJECTIVE To compare neonatal outcomes (including breastfeeding (BF) initiation) of 170 macrosomic IDM with that of 739 macrosomic nIDM. DESIGN/METHODS Retrospective cohort investigation of all macrosomic infants born consecutively over a four-year period (2008-2011). Macrosomic (birth weight ≥4000 g) IDM included 100 infants whose mothers had gestational diabetes and 70 whose mothers had pregestational diabetes. RESULTS IDM were more likely to be delivered by cesarean to obese women while nIDM were more likely to be delivered vaginally to younger women with a higher level of education. Ethnic distribution (60% white, 20% black, 10% Hispanic and 10% Asian or African) was similar in each group. Forty-nine percent of IDM and 7% of nIDM required NICU admission. Respiratory disorders (mainly TTNB) affected 21% of IDM and 3% of nIDM while hypoglycemia was observed in 36% of IDM and 15% of nIDM. Of the 35 IDM delivered vaginally, 10 were complicated by shoulder dystocia without injury. Conversely, 70 of the 458 nIDM delivered vaginally experienced shoulder dystocia that resulted in 6 limb fractures and 3 brachial plexus injuries. On arrival to labor and delivery, 75% of all women intended to BF; however, at the time of discharge, 65% of women with diabetes and 92% of those without diabetes who intended to BF had initiated BF. CONCLUSIONS Both macrosomic IDM and macrosomic nIDM are at risk for significant morbidities. Macrosomic IDM carry a higher risk for NICU admissions, leading to maternal-infant separation, and lower BF initiation rates.

Abstract
OBJECTIVES Construct an ethnic-specific chart and compare the prediction of adverse outcomes using this chart with the clinically recommended UK-WHO and customised birth weight charts using cut-offs for small-for-gestational age (SGA: birth weight <10th centile) and large-for-gestational age (LGA: birth weight >90th centile). DESIGN Prospective cohort study. SETTING Born in Bradford (BiB) study, UK. PARTICIPANTS 3980 White British and 4448 Pakistani infants with complete data for gestational age, birth weight, ethnicity, maternal height, weight and parity. MAIN OUTCOME MEASURES Prevalence of SGA and LGA, using the three charts and indicators of diagnostic utility (sensitivity, specificity and area under the receiver operating characteristic (AUROC)) of these chart-specific cut-offs to predict delivery and neonatal outcomes and a composite outcome. RESULTS In White British and Pakistani infants, the prevalence of SGA and LGA differed depending on the chart used. Increased risk of SGA was observed when using the UK-WHO and customised charts as opposed to the ethnic-specific chart, while the opposite was apparent when classifying LGA infants. However, the predictive utility of all three charts to identify adverse clinical outcomes was poor, with only the prediction of shoulder dystocia achieving an AUROC>0.62 on all three charts. CONCLUSIONS Despite being recommended in national clinical guidelines, the UK-WHO and customised birth weight charts perform poorly at identifying infants at risk of adverse neonatal outcomes. Being small or large may increase the risk of an adverse outcome; however, size alone is not sensitive or specific enough with current detection to be useful. However, a significant amount of missing data for some of the outcomes may have limited the power needed to determine true associations.

Abstract
INTRODUCTION AND HYPOTHESIS Pelvic organ prolapse (POP) in pregnancy is a rare condition with decreasing incidence and improved management and outcome world-wide recently. Systematic review of the literature for cases of POP in pregnancy published since 1990 was carried out to identify common factors in presentation, management and outcomes. One case from our own practice was added to the analysis. METHODS An extensive search of the Pubmed/Medline, Scopus and Google Scholar databases was performed to identify all cases of POP in pregnancy since 1990. Published case reports of POP in pregnancy were reviewed and summarized in tables to find similarities in history, course, management and outcome of the pregnancies. RESULTS Of the 43 cases and one case series, 41 case studies were eligible for analysis. Two types of POP in pregnancy were identified: preexisting is less common (14 vs 27 cases), often resolves during pregnancy (5 out of 14) and always recurs after delivery (14 out of 14); acute onset of POP in pregnancy rarely resolves in pregnancy (2 out of 27), but often resolves after delivery (18 out of 27). Most patients were managed with bed rest (20 out of 41), pessary (15 out of 41), manual reduction (6 out of 41) and local treatment (6 out of 41). The most common complications reported include preterm labour (14 out of 41), cervical ulcerations (9 out of 41), infection (3 out of 41) and obstructed labour (4 out of 41). About a half of the women delivered vaginally (22 out of 41), caesarean section due to prolapse was required in 15 cases. CONCLUSIONS Two distinct entities were identified based on similarities regarding onset, course and outcome of POP in pregnancy. Concise recommendations for practice were derived from the analysis of case studies published since 1990.

Abstract
OBJECTIVE To investigate the risk factors, clinical prediction and intrapartum management of shoulder dystocia in non-macrosomia. METHODS Totally 7 811 cases of vaginal delivery were retrospectively reviewed from Juanary 2009 to December 2013 in Shengjing Hospital. Shoulder dystocia was found in 11 cases (0.14% , 11/7 811), including 1 case of macrosomia and 10 cases of non-macrosomia (shoulder dystocia group). Each non-macrosomia shoulder dystocia case was matched with 10 cases of normal delivery in the same week, which were selected randomly as the control group. The tendency and risk factors of shoulder dystocia in macrosomia and non-macrosomia were analyzed, and the following data between the two groups were compared, including the height of uterus fundus, abdominal circumference of the pregnant woman, the increasing of body mass index (BMI), fetal biparietal diameter (BPD), fetal femur length (FL), duration of every stage of labor, birth weight of the newborn, head circumference and chest circumference of the newborn, Apgar score. RESULTS (1) There were 213 macrosomias among the 7 811 vaginal deliveries, with the incidence of 2.73% (213/7 811). Only 1 shoulder dystocia was macrosomia (0.46%, 1/213); while the other 10 cases were non-macrosomia ( 0.13%, 10/7 598). (2) From 2009 to 2013, the macrosomia happened by 24 cases (2.32%, 24/1 034), 42 cases (3.61%, 42/1 164), 46 cases (2.60%, 46/1 772), 62 cases (3.01%, 62/2 060), 39 cases (2.19%, 39/1781), respectively. The incidence of macrosomia had no significant difference among these 5 years (P > 0.05). The shoulder dystosia occurrence without macrosia in these 5 years were 1 case ( 0.10% , 1/1 034), 3 cases (0.26%, 3/1 164), 2 cases ( 0.11%, 2/1 172), 2 cases (0.10%, 2/2 060), 2 cases ( 0.11%, 1/1 781), respectively. The incidence of shoulder dystocia without macrosomia had no significant difference among these 5 years (P > 0.05). (3) In the should dystocia group, 5 cases were complicated with premature rupture of membrane (5/10), 4 cases were mother≥ 35 years old (4/10), 3 cases were multipara(3/10), 3 cases had gestational diabetes mellitus(3/10), 3 cases were occiput posterior during the first stage of labor (3/10), 3 cases had prolonged second stage of labor (3/10) and 6 cases had routine lateral incision (6/10). In the control group, 3 cases were complicated with premature rupture of membrane(3/10); 1 case was mother≥35 years old (1/10); 2 cases were multipara(2/10), 3 cases had gestational diabetes mellitus (3/10), 1 case had prolonged second stage (1/10) and 7 cases had routine lateral incision (7/10). (4) There were no significant difference in the height of uterus fundus, BMI, BPD, FL, and duration of the first stage of labor between the shoulder dystocia group and the control group (P > 0.05). Compared with the control group, the increasing of BMI [(6.8±3.1) vs (4.8±1.4) kg/m(2)], the time of the second stage of labor[(86±65) vs (38±28) minutes ] and abdominal circumference[(108±8) vs (101±7) cm] were significantly higher in the shoulder dystosia group (P < 0.05). (5) There were significant difference in the chest circumference of the newborn [(34.0±1.6) vs (32.2±1.9) cm ] and the ratio of chest circumference to head circumference of the newborn [(0.99±0.03) vs (0.97±0.03) ] between the two groups (P < 0.05). The 1-minute Apgar score of the newborn (7.4±2.8) was significantly lower than the control group (10.0±0.0) (P < 0.01). Clavicular fracture occurred in 3 newborns and brachial plexus injury occurred in 4 newborns in the shoulder dystosia group. CONCLUSION It is difficult to predict shoulder dystocia in non-macrosomia. Shoulder dystocia of non-macrosomia could be predicted by measurement of the head circumference, chest circumference, the ratio of chest circumference to head circumference by using prenatal ultrasound. The risk factors may complicated with premature rupture of membrane, abnormal occiput position during the first stage of labor and prolonged second stage of labor.

Abstract
BACKGROUND Little is known about the optimal cut-off point of fasting plasma glucose for the diagnosis of gestational diabetes mellitus for pregnant Chinese women. This study investigates the relationship between gestational fasting plasma glucose and several variables: neonatal birth weight, prenatal blood pressure and dystocia rate of pregnant women. In this study, we hoped to provide a useful tool to screen gestational diabetes mellitus in pregnant Chinese women. METHODS For 1058 pregnant women enrolled in our hospital at pregnancy weeks 22-30, fasting plasma glucose, neonatal birth weight and prenatal blood pressure, as well as dystocia conditions, were examined. We analysed the correlations between the following: gestational fasting plasma glucose and neonatal birth weight; prenatal blood pressure and gestational fasting plasma glucose as well as dystocia rate and gestational fasting plasma glucose group. RESULTS A modest correlation was observed between gestational fasting plasma glucose and neonatal birth weight (r = 0.093, p = 0.003). The macrosomia rate was smallest when the gestational fasting plasma glucose was in the range 3.51-5.5 mmol/L. Prenatal blood pressure increased linearly with increasing gestational fasting plasma glucose (p = 0.000). There was a significant difference between the dystocia rates in different fasting plasma glucose groups (chi-squared = 13.015, p = 0.043). The results showed that the dystocia rate significantly increased when gestational fasting plasma glucose was >4.9 mmol/L; p = 0.03, OR = 2.156 (95% CI, 1.077-4.318). CONCLUSION We suggest that the optimal range of gestational fasting plasma glucose for pregnant Chinese women is in the range 3.5-4.9 mmol/L.

Abstract
OBJECTIVE The objective of the study was to determine the threshold for defining abnormal labor that is associated with adverse maternal and neonatal outcomes. STUDY DESIGN This study consisted of a retrospective cohort of all consecutive women admitted at a gestation of 37.0 weeks or longer from 2004 to 2008 who reached the second stage of labor. The 90th, 95th, and 97th percentiles for progress in the first stage of labor were determined specific for parity and labor onset. Women with a first stage above and below each centile were compared. Maternal outcomes were cesarean delivery in the second stage, operative delivery, prolonged second stage, postpartum hemorrhage, and maternal fever. Neonatal outcomes were a composite of the following: admission to level 2 or 3 nursery, 5 minute Apgar less than 3, shoulder dystocia, arterial cord pH of less than 7.0, and a cord base excess of -12 or less. RESULTS Of the 5030 women, 4534 experienced first stage of less than the 90th percentile, 251 between the 90th and 94th percentiles, 102 between the 95th and 96th percentiles, and 143 at the 97th percentile or greater. Longer labors were associated with an increased risk of a prolonged second stage, maternal fever, the composite neonatal outcome, shoulder dystocia, and admission to a level 2 or 3 nursery (P < .01). Depending on the cutoff used, 29-30 cesarean deliveries would need to be performed to prevent 1 shoulder dystocia. CONCLUSION Although women who experience labor dystocia may ultimately deliver vaginally, a longer first stage of labor is associated with adverse maternal and neonatal outcomes, in particular shoulder dystocia. This risk must be balanced against the risks of cesarean delivery for labor arrest.

Abstract
Les jumeaux conjoints sont considérés comme étant une complication rare et grave des grossesses monozygotes. Le diagnostic anténatal permet de définir avec précision les structures communes, de rechercher une anomalie congénitale associée, d'organiser l´accouchement et la prise en charge néonatale. Nous présentons un cas rare de jumeaux conjoints dont la fusion se situait au niveau d'une omphalocèle commune associée à une extrophie cloacale, ambiguïté sexuelle et pieds bots. Le diagnostic a été méconnu pendant la grossesse, ce qui a engendré une dystocie lors de l'accouchement. L'issue a été fatale malgré une tentative de séparation et des mesures de réanimation. Ce cas illustre la difficulté liée d'une part à la méconnaissance du diagnostic, d'autre part au caractère urgent de la césarienne et de la séparation chirurgicale.

Abstract
OBJECTIVE To evaluate the quality of anthropometric measures to improve the prediction of shoulder dystocia by combining different sonographic biometric parameters. METHODS This was a retrospective cohort study of 12,794 vaginal deliveries with complete sonographic biometry data obtained within 7 days before delivery. Receiver-operating characteristics (ROC) curves of various combinations of the biometric parameters, namely, biparietal diameter (BPD), occipitofrontal diameter (OFD), head circumference, abdominal diameter (AD), abdominal circumference (AC) and femur length were analyzed. The influences of independent risk factors were calculated and their combination used in a predictive model. RESULTS The incidence of shoulder dystocia was 1.14%. Different combinations of sonographic parameters showed comparable ROC curves without advantage for a particular combination. The difference between AD and BPD (AD - BPD) (area under the curve (AUC) = 0.704) revealed a significant increase in risk (odds ratio (OR) 7.6 (95% CI 4.2-13.9), sensitivity 8.2%, specificity 98.8%) at a suggested cut-off ≥ 2.6 cm. However, the positive predictive value (PPV) was low (7.5%). The AC as a single parameter (AUC = 0.732) with a cut-off ≥ 35 cm performed worse (OR 4.6 (95% CI 3.3-6.5), PPV 2.6%). BPD/OFD (a surrogate for fetal cranial shape) was not significantly different between those with and those without shoulder dystocia. The combination of estimated fetal weight, maternal diabetes, gender and AD - BPD provided a reasonable estimate of the individual risk. CONCLUSION Sonographic fetal anthropometric measures appear not to be a useful tool to screen for the risk of shoulder dystocia due to a low PPV. However, AD - BPD appears to be a relevant risk factor. While risk stratification including different known risk factors may aid in counseling, shoulder dystocia cannot effectively be predicted.

Abstract
Birth injuries are frequently seen in newborn infants. Clavicular fractures are the most commonly encountered bony injuries seen in clinical practice. The incidence of clavicle fracture ranges from 0.35 per cent to 2.9 per cent of births and remains undetected at the time of discharge from hospital in up to 40 per cent of cases. Clinical suspicion of fractured clavicle may be raised from history (shoulder dystocia) or clinical examination (spongy feeling or crepitus on palpation). This should be confirmed with imaging studies. Parents should have the diagnosis explained and be reassured that healing without residual deformity will occur without any medical intervention. Careful documentation of any confirmed clavicle fracture is important from medico-legal aspects. We present the case of a newborn clavicular fracture associated with shoulder dystocia, following a vaginal birth,.

Abstract
Fetal macrosomia and maternal diabetes are independent risk factors for shoulder dystocia, an obstetrical emergency that may cause permanent neonatal injury. Randomized trials of glycemic control in pregnancies complicated by gestational diabetes reveal decreased rates of macrosomia and shoulder dystocia among those treated. However, definitions of gestational diabetes vary and a specific glycemic threshold for clinically significant risk reduction remains to be delineated. This review discusses risks associated with gestational diabetes including macrosomia (birth weight above 4000-4500 g) and delivery-related morbidity, specifically, shoulder dystocia. Subsequently, we will review recent randomized trials assessing the impact of glycemic control on these delivery-related morbidities. Finally, we will examine a large observational study that found associations with delivery-related morbidity and hyperglycemia below current diabetic thresholds, observations which may suggest reexamination of current diagnosis guidelines for gestational diabetes.

Abstract
Birth injuries are devastating to parents and carers alike. They carry the possibility of residual loss of function to the infant and thus the potential for litigation. The aim of this study was to determine the incidence of Erb-Duchenne's palsy and the identification of any contributing factors. A retrospective review over a five-year period, 2005-2009, was performed and an incidence of 0.94 per 1000 live births was noted. An association between both macrosomia and shoulder dystocia and the development of Erb-Duchenne palsy in the newborn was noted. The authors recommended the use of partograms and improved note documentation in the management of labour.

Abstract
Vaginal leiomyomas are rare benign solid tumours of the vagina. They can cause mechanical dystocia, which is a common problem in obstetrics leading to serious maternal and perinatal complications. Here we describe a patient with a vaginal leiomyoma diagnosed during the mid-trimester that could have caused dystocia. This 22-year-old woman presented with a vaginal mass and leaking vaginal fluid during pregnancy. On examination, a prolapsed, pedunculated mass, measuring 5 × 3 × 4 cm was detected in the anterior vaginal wall. Via a midline incision, the mass was easily enucleated and removed. Transvaginal surgical enucleation of the vaginal leiomyoma is usually curative and recommended as the initial treatment of choice to prevent for dystocia. Such treatment is indicated when the tumour is a potential obstacle to normal labour.

Abstract
AIMS To evaluate the effectiveness of gestational diabetes (GDM) treatment compared to usual antenatal care, in the prevention of adverse pregnancy outcomes. Additionally, to assess the quality of the evidence to support GDM treatment according to GRADE guidelines. METHODS Fourteen electronic databases and reference lists of relevant literature were searched for articles published from inception to February, 2012. Controlled clinical trials comparing GDM treatment to usual antenatal care were included. Independent extraction of articles was done by two authors using predefined data fields. RESULTS Seven trials involving 3157 women were included. We found high quality evidence that treatment of GDM reduces macrosomia (RR=0.47; 95% CI, 0.34-0.65; NNT=11.4) and large for gestational age birth (RR=0.57; 95% CI, 0.47-0.71; NNT=12.2); moderate quality evidence that treatment reduces preeclampsia (RR=0.61; 95% CI, 0.46-0.81; NNT=21.0) and hypertensive disorders in pregnancy (RR=0.64; 95% CI, 0.51-0.81; NNT=18.1); and low quality evidence that treatment reduces shoulder dystocia (RR=0.41; 95% CI, 0.22-0.76; NNT=48.8). No statistically significant reduction was seen for caesarean section. No increase in small for gestational age or preterm birth was found. CONCLUSIONS Treatment of GDM is effective in reducing macrosomia (high quality evidence), preeclampsia and shoulder dystocia.

Abstract
OBJECTIVE To evaluate whether fetal cranial shape is related to shoulder dystocia. METHODS We compared shoulder dystocia cases (n = 18) with controls (normal vaginal deliveries, n = 18) in a retrospective matched-pairs observational study. Subjects were matched for known maternal and fetal risk factors and then evaluated for fetal biometric differences, which were measured by ultrasound near delivery. We tested multivariable risk models to predict shoulder dystocia by logistic regression. RESULTS Cases had a smaller estimated occipitofrontal diameter (OFD) (P = 0.02) and a larger biparietal diameter/estimated OFD ratio (P = 0.003). A multivariable model including estimated fetal weight, estimated OFD, maternal weight and diabetes mellitus had sensitivity and specificity of 86% and 95%, respectively, and positive and negative likelihood ratios of 18.9 and 0.15, respectively. Estimated OFD significantly increased the predictive value of the model. CONCLUSION A small estimated OFD is a risk factor for shoulder dystocia in the presence of other significant risk factors. A multivariable model including estimated OFD can predict shoulder dystocia in a clinically useful range.

Abstract
UNLABELLED Aim of the present study was to summarize the available literature about the incidence, frequency, clinical symptoms and ideas as to the pathogenesis of uterine torsion in the cow. MATERIALS AND METHODS Analysis of the literature using electronic libraries (Pub Med, Medline), German veterinary medicine journals and obstetrical textbooks. RESULTS Uterine torsion is a very important maternal reason for dystocia as most cases occur during parturition. The post-cervical torsion (combined uterine and vaginal torsion, Torsio uteri and vaginae) is more commonly diagnosed than an intra-cervical or pre-cervical torsion. Torsions to the left occur more frequently than to the right. Clinical symptoms clearly vary depending on the degree of torsion. The frequency in relation to all parturitions is described as between 0.5 and 1%, whereas the percentage of uterine torsions presented to the veterinarian as a reason for dystocia varies between 2.7 and 65%. The pathogenesis of uterine torsion remains unclear; however, general agreement exists that the cow is predisposed to uterine torsion due to its anatomy. It appears that the Brown Swiss is more often affected than other cattle breeds.

Abstract
BACKGROUND Severe shoulder dystocia is disproportionately associated with large-for-gestational-age infants. CASE A nulliparous patient at 38 weeks' gestation had an uncomplicated antenatal course. Clinical pelvimetry revealed an acute-angle pubic arch but otherwise normal diameters, conjugate and sacral concavity. Pre-pregnancy BMI was 20.8 and she had had a 14-pound (6.4 kg) weight gain. She presented in labor and, with oxytocin augmentation, progressed to full dilation over 6 hours, followed by an 18-minute second stage. Severe shoulder dystocia was encountered, necessitating multiple maneuvers, and was resolved after 2 minutes with delivery of the posterior arm. The healthy infant weighed 2,289 g (< 5th percentile) and exhibited only transient shoulder weakness, which resolved completely within 1 hour of life. With informed consent, CT pelvimetry was performed within 24 hours postpartum for investigative purposes, revealing small pelvic inlet and at-threshold interischial diameter. CONCLUSION Geometric analysis reveals that borderline adequate pelvimetry likely played a significant role in severe shoulder dystocia etiology, even with a small-for-gestational-age infant. We alert obstetric providers to the possibility of severe shoulder dystocia in patients with borderline adequate pelves on clinical examination, even when estimated fetal weight makes cephalopelvic disproportion unlikely.

Abstract
The primary indication for cesarean section in nulliparous women continues to be clinical diagnoses that fall under the rubric of dystocia. These diagnoses account for approximately two-thirds of all cesareans experienced by otherwise healthy nulliparous women. Contemporary research evidence suggests that this clinical phenomenon is complex and multifactorial. This review explores factors associated with the phenomenon of dystocia in the context of a conceptual model that considers women's physical and psychological characteristics, fetal factors, intrapartum care and interventions, assessments and clinical decision-making of health care providers, the sociopolitical environment, and the social and physical environment of childbirth. Clinical recommendations include emphasis on the maintenance of normal weight and weight gain during pregnancy, delaying the admission of nulliparous women to the hospital until active labor is established, avoiding elective induction for nulliparous women, keeping women well-hydrated and well-fed during labor, providing high-quality supportive care during labor, staying the course with effective treatment when dystocia is encountered, and a renewed emphasis on the psychobehavioral preparation of nulliparous women for the realities of labor.

Abstract
OBJECTIVE To develop a scoring system for the detection of a macrosomic fetus (birth weight (BW) >or= 4000 g) and predict shoulder dystocia among large for gestational age fetuses. STUDY DESIGN We retrospectively identified all singletons with accurate gestational age (GA) that were large for GA (abdominal circumference (AC) or estimated fetal weight (EFW) >or= 90% for GA) at >or=37 weeks with delivery within three weeks. The scoring system was: 2 points for biparietal diameter, head circumference, AC, or femur length >or=90% for GA, or if the amniotic fluid index (AFI) was >or=24 cm; for biometric parameters <90% or with AFI <24 cm, 0 points. The predictive values for detection of shoulder dystocia were calculated. RESULTS Of the 225 cohorts that met the inclusion criteria the rate of macrosomia was 39% and among vaginal deliveries (n = 120) shoulder dystocia occurred in 12% (15/120; 95% confidence interval (CI) 7-20%). The sensitivity of EFW >or=4500 g to identify a newborn with shoulder dystocia was 0% (95% CI 0-21%), positive predictive values 0% (95% CI 0-46%), and likelihood ratio of 0. For a macrosomia score >6, the corresponding values were 20% (4-48%), 25% (5-57%) and 2.3. CONCLUSION Though the scoring system can identify macrosomia, it offers no advantage over EFW. The scoring system and EFW are poor predictors of shoulder dystocia.

Abstract
OBJECTIVE To delineate factors that differentiate shoulder dystocia with and without brachial plexus injury (BPI). STUDY DESIGN A case-control study culled from an established shoulder dystocia database. Cases of shoulder dystocia-related BPI were identified and matched (1:1) with a control group of shoulder dystocia in which BPI did not result. Odds ratios (OR) and 95% confidence intervals (CI) were calculated. RESULTS From 1980 to 2002, there were 89 978 deliveries with 46 cases of dystocia and BPI. The rate of dystocia with BPI was 0.5 per 1000 births and of permanent BPI, 0.9/10 000 deliveries. The two groups were similar for maternal demographics, diabetes, gestational age, induction, use of epidural, the duration of labor, operative vaginal delivery, rate of macrosomia, and maneuvers used to relieve the dystocia. Fracture of the clavicle occurred significantly less often among those without (2%) vs. with BPI (17%; OR 0.10, 95% CI 0.01, 0.88). CONCLUSIONS Neither antepartum nor intrapartum factors can differentiate the patient who will have shoulder dystocia with vs. without BPI.

Abstract
One thousand and thirteen (1013) symphysiotomies were performed and 27,477 deliveries were conducted during the period. The symphysiotomy rate in the study period was 3.7%. Fifty-six percent (56%) of the patients who had symphysiotomy were aged 39 years and below, and the mean age was 27.94 +/- 7.16 years. Mothers with maternal age greater than 40 years were at a higher risk for symphysiotomy. Thirty-eight percent (38%) of those who had symphysiotomy were nulliparae, 35% were multiparae, while grandmultiparae accounted for 27%. Cephalopelvic disproportion was the leading indication for symphysiotomy (88%), while arrest of the after-coming head of the breech and previous caesarean section with mild cephalopelvic disproportion were other indications for symphysiotomy. Transient post-operative pelvic and leg pain was the leading maternal complication in the study, while stress incontinence, para urethra/vagina lacerations and vesico-vagina fistula were the other complications highlighted. In the study, 69% of the symphysiotomies performed were for babies with birth weight between 3.0 and 3.9 kg. The record of one maternal death was available and was from massive pulmonary embolism on the third day postpartum. There were 104 perinatal deaths with a perinatal mortality rate of 108.7 per 1000 total births.

Abstract
We carried out a descriptive analysis on the pregnancy outcome in 313 pregnant women abused, 160 non-abused). Abuse was statistically significantly correlated with mean weight gain during pregnancy, mean frequency of the prenatal care, prolonged labour (dystocia), premature rupture of membrane, low mean birth weight and mean gestational age at birth. Given the high likelihood that a woman will access health care services during her pregnancy, physicians providing prenatal care are in a strategic position to screen for partner abuse.

Abstract
Reviewing the areas of controversy related to the obstetric management of women with GDM, we are unfortunately unable to provide significant refinement of the recommendations agreed upon after the Fourth International Workshop-Conference due to the lack of properly controlled and powered clinical studies in this area since 1997. In the area of the need for antenatal fetal surveillance in women with milder degrees of GDM, we may be able to draw indirect conclusions from ongoing cohort studies that will include large numbers of women. In the area of optimal timing and mode of delivery to avoid fetal injury, large well-controlled prospective studies do not currently exist and are urgently needed. In addition, refinement of fetal and pelvic imaging techniques to more accurately identify the maternal-fetal pairs most likely to benefit from avoiding vaginal delivery, and the more widespread availability of these technologies, may also prove to be of benefit in the obstetric management of women with GDM.
