Twin reversed arterial perfusion sequence (TRAP), refers to a rare, unique complication of mono-chorionic twin pregnancy in which a twin with an absent or a nonfunctioning heart (acardiac twin) is perfused by its co-twin (pump twin) via placental arterial anastomoses. The acardiac twin usually has a poorly developed heart, upper body and head. The pump twin is at risk of heart failure and probl...

Background: The Lori-Bakhtiari sheep breed is one of the most common native breed in the south-western parts of Iran. The peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. OBJECTIVES: This study was carried out to compare the serum concentrations of glucose, non-esterified f...

cystic fibrosis is an inheritant autosomal recessive disease. it is associated with mutations in cystic fibrosis trans regulator gene (cftr) and has different presentations.we report two 2 month old female patients, products of a twin delivery presented with anemia, edema, hypoalbuminemia and pneumonia.after some work ups, diagnosis of cystic fibrosis was confirmed. this is an uncommon and inte...

The purpose of this study was to determine the effect of twin-to-twin delivery interval on umbilical artery acid-base status of the second twin at birth. This was a retrospective cohort study of all live-born twins with measured acid-base status in umbilical arterial blood who were delivered after 34 weeks' gestation from June 2003 to February 2006. Twins with any maternal or fetal complication...

OBJECTIVE The objective of the study was to determine the incidence, origin, and character of cerebral lesions in monochorionic twins with twin-to-twin transfusion syndrome treated with fetoscopic laser surgery. STUDY DESIGN This was a prospective study of monochorionic twins with twin-to-twin transfusion syndrome treated with fetoscopic laser surgery and monochorionic twins without twin-to-t...

Fetus in fetu is an extremely rare condition embryologically arising in monozygotic diamniotic twins with an incidence of 1:500,000 births. To the best of our knowledge, number of reported cases should not be more than 100 with majority of cases presenting in post natal life with only 5 cases detected prenatally. We are presenting a case diagnosed at 24 weeks of gestation on ultrasound with pre...

We conducted an AX-discrimination task to test for differences in perceived auditory similarity in monozygotic (MZ) and dizygotic (DZ) twin pairs and unrelated speakers. In addition, we performed acoustic analyses to find acoustic correlates that explain the differences in perceived similarity. Results indicate that unrelated speakers are significantly easier to distinguish than twins, but zygo...

BACKGROUND The objective was to examine the effect of twin-to-twin delivery intervals on neonatal outcome for second twins. METHODS This was a retrospective, hospital-based study, performed at a university teaching hospital in Western Sweden. Twin deliveries between 2008 and 2014 at ≥32 + 0 weeks of gestation, where the first twin was delivered vaginally, were included. Primary outcome was a ...

Background: Twin pregnancy consist a healthy fetus, and hydatidium molar pregnancy is unusual and very rare. Its incidence is in about 1,22,000 to 1,100,000 of all pregnancies. This type of pregnancy is commonly associated with several obstetric complications requiring early termination of pregnancy. Managing a twin mole pregnancy with normal and live fetuses is controversial, although this unu...
