BACKGROUND: Craniopagus parasiticus is rare with an incidence of approximately four to six cases in 10,000,000 births. In our case, the head of the parasitic twin protruded from the temporal area of the normal twin's cranium. The parasitic twin had two deformed lower limbs, of which one was rudimentary, and long bones of the bilateral lower limbs and some pelvic bone. Dissection of the mass of the parasitic twin's body revealed the intestine but no chest organs or abdominal organs. There was a rudimentary labium but no vaginal opening...

INTRODUCTION: Cesarean delivery (CD) rates are rising due to multiple factors, including less use of operative vaginal delivery (OVD) and vaginal birth after cesarean delivery (VBAC), which often reflect local obstetric practices. Objectives of the study were to analyze the relations between CD, these practices and perinatal outcomes. MATERIAL AND METHODS: We included all deliveries in the 72 hospitals of Lombardia, a Region in Northern Italy, during the year 2013...

INTRODUCTION: Most women who give birth for the first time experience some form of perineal trauma. Second-degree tears contribute to long-term consequences for women and are a risk factor for occult anal sphincter injuries. The objective of this study was to evaluate a multifaceted midwifery intervention designed to reduce second-degree tears among primiparous women. METHODS: An experimental cohort study where a multifaceted intervention consisting of 1) spontaneous pushing, 2) all birth positions with flexibility in the sacro-iliac joints, and 3) a two-step head-to-body delivery was compared with standard care...

BACKGROUND: Low concentrations of local anesthetics (LCLAs) are increasingly popular for epidural labor analgesia. The effects of epidural analgesia with low concentrations of anesthetics on the duration of the second stage of labor and the instrumental birth rate, however, remain controversial. A systematic review was conducted to compare the effects of epidural analgesia with LCLAs with those of nonepidural analgesia on obstetric outcomes. METHODS: The databases of PubMed, Embase, and the Cochrane controlled trials register were independently searched by 2 researchers, and randomized controlled trials that compared epidural labor analgesia utilizing LCLAs with nonepidural analgesia were retrieved...
