BACKGROUND: Breech presentation is a leading cause of cesarean delivery. The use of neuraxial anesthesia increases the success rate of external cephalic version procedures for breech presentation and reduces cesarean delivery rates for fetal malpresentation. Meta-analysis suggests that higher-dose neuraxial techniques increase external cephalic version success to a greater extent than lower-dose techniques, but no randomized study has evaluated the dose-response effect. We hypothesized that increasing the intrathecal bupivacaine dose would be associated with increased external cephalic version success...

The essential role of ultrasound examinations in diagnosis and treatment of developmental dysplasia of the hip (DDH) is widely accepted while the weighting and correlation of protective factors and perinatal risk for DDH still give rise to debate. Our aim was to investigate the impact of single and twofold combined risk and protective factors on the newborns' hip maturity, assessed with the Graf ultrasound method. Therefore, data sets of 11,820 universally screened newborns were analyzed. Univariate and logistic regression analyses were performed to correlate risk and protective factors with mature or immature but appropriate for age and pathologic hip types...

INTRODUCTION: Recent research has demonstrated that the media presentation of childbirth is highly medicalized, often portraying birth as risky and dramatic. Media representation of breech presentation and birth is unexplored in this context. This study aimed to explore the content and tone of news media reports relating to breech presentation and breech birth. METHODS: Google alerts were created using the terms breech and breech birth in online English-language news sites over a 3-year period from January 1, 2013, to December 31, 2015...

INTRODUCTION: Although caesarean section rates have been increasing over the years in both public and private sectors in Hong Kong, there has been a paucity of formal surveys on local trends in such rates. This study aimed to examine the trends in caesarean section rates over a 20-year period at a public regional obstetric unit in Hong Kong using the Robson's Ten-group Classification System. METHODS: All deliveries in a single obstetric unit during a 20-year period (1995-2014) were classified into 10 subgroups according to the Robson's classification...

In the last decades the exponential increase in frequency of Caesarean sections is being observed. At the same time, there is growing amount of epidemiologic data showing higher lifetime risk of incidence of several diseases in offspring who do not experience natural labour. These findings lead to investigation of mechanisms which are responsible for maladaptation of several organ systems. Authors of this article describe these mechanisms, focusing especially on epigenetic programming, production of microbiome and positive effect of peripartal stress on successful beginning of extrauterine life...

INTRODUCTION: The most common fractures during vaginal delivery occur in the clavicle, humerus, and femur. Cesarean section reduces the chances of a child having a birth injury. However, in some difficult extractions, long bone fractures may occur. Cesarean section further reduces the incidence of birth injuries, especially in a breech delivery. Maneuvers employed during cesarean section, energetic traction, improper uterine incisions, and contracted uterus may cause these injuries. In the medical literature, there are few articles highlighting the occurrence of long bone fractures during cesarean section...

We report the case of a 36-year old man who underwent elective posterior lumbar spinal fusion after presenting with bilateral leg pain with associated back pain. He had undergone a L5/S1 discectomy in 2001, which provided good symptomatic relief. On this admission, he underwent elective L4-S1 posterolateral fusion and bilateral L4/5 and L5/S1 decompression. Intra-operatively a pedicle screw had to be re-inserted after fluoroscopy confirmed a lateral breech. The patient had no major postoperative complications until the sixth day when the patient re-presented with acute leg pain and weakness...

OBJECTIVE: To analyze the benefits of external cephalic version (ECV) with epidural analgesia at term and labor induction just after the procedure. MATERIALS AND METHODS: This is a retrospective observational study with patients who did not want trying a breech vaginal delivery and decided trying an ECV with epidural analgesia at term and wanted labor induction or cesarean section after the procedure. We present the results of 40 ECV with epidural analgesia at term and labor induction or cesarean section just after the ECV...

Many studies have been performed in recent years in the field of firearm examination with the goal of providing an objective method for comparisons of fired cartridge cases. No published research to support the number of test fires needed to represent the variability present within the impressions left on a cartridge case could be found. When a suspect firearm is submitted to a firearm examiner, typically two to four test fires are performed. The recovered cartridge cases are compared to each other to determine which characteristics from the firearm are reproducing, and then compared to any cartridge cases collected at a crime scene...

BACKGROUND: Breech presentation affects 3-4% of pregnancies at term and malpresentation is the primary indication for 10-15% of cesarean deliveries. External cephalic version is an effective intervention that can decrease the need for cesarean delivery; however, timely identification of breech presentation is required. We hypothesized that women with a fetus in a breech presentation that is diagnosed after 38 weeks' estimated gestational age have a decreased likelihood of external cephalic version attempted and an increased likelihood of cesarean delivery...

INTRODUCTION: Developmental dysplasia of the hip (DDH) refers to the spectrum of abnormalities of maturation and development of the hip. Breech presentation is associated with DDH. This risk factor can be modified by external cephalic version (ECV). The aim of this study is to evaluate the incidence of DDH in patients who successfully underwent ECV, as well as to evaluate need for these children (breech for a period during gestation) to be included in the DDH screening protocol. MATERIAL AND METHODS: A prospective cohort study was conducted in the Hospital Universitario de Vigo from January 1, 2015 to December 31, 2015...

BACKGROUND: Growing evidence suggests that cesarean scar pregnancy (CSP) and morbidly adherent placenta (MAP) may represent a continuum of the same disease. OBJECTIVES: To investigate and compare the prior risk factors in women with either CSP or MAP. METHODS: The study included 33 women diagnosed with CSP in our department between 2006 and 2014. For each CSP case, two pregnant patients with MAP were matched for hospitalization date from delivery ward records, constituting the control group...

INTRODUCTION: Among women with a fetus with a non-cephalic presentation, external cephalic version (ECV) has been shown to reduce the rate of breech presentation at birth and cesarean birth. Compared with ECV at term, beginning ECV prior to 37 weeks' gestation decreases the number of infants in a non-cephalic presentation at birth. The purpose of this secondary analysis was to investigate factors associated with a successful ECV procedure and to present this in a clinically useful format...

BACKGROUND: The clinical significance and management of preterm premature rupture of membranes (PPROM) remains a topic of a controversy. Although PROM is associated with a low rate of complications, PPROM may lead to significant neonatal and maternal morbidity. METHODS: We performed a retrospective study of 714 women who presented to Jiangsu Province Hospital with third trimester PPROM or PROM between January and December 2015. The data were analyzed by SPSS; the significance of maternal characteristics, and maternal and neonatal outcomes were tested using Student's t test and the χ(2) test...

INTRODUCTION: While evidence suggests that beginning an external cephalic version (ECV) before term (34(0/7) to 36(6/7) weeks) compared with after term may be associated with an increase in late preterm birth (34(0/7) to 36(6/7) weeks), it remains unknown what might account for this risk. The objective of the present study is to further investigate the association between ECV before term and late preterm birth. MATERIAL AND METHODS: Secondary analysis of data collected from the international, multicenter Early ECV trials...
