ABSTRACT The aim of this study was to compare maternal and neonatal outcome of twin births according to mode of delivery and to isolate the factors predicting a successful vaginal delivery and those predicting a failed trial of labor (TOL) leading to an emergent cesarean section. We reviewed all twin deliveries during the years 1995 to 2004. Parameters studied include maternal age, parity, gestational age, maternal antepartum complications and postpartum complications, fetal presentations, birthweight, mode of delivery of each twin, Apgar scores and cord pH. During the study period there were 40,710 deliveries of which 804 (1.9%) were twin deliveries. Of the 804 twins, 398 (49.5%) had planned cesarean sections (PCS) and 406 (50.5%) entered a TOL. Maternal age and parity were similar among the groups. Neonatal outcomes and postpartum complications did not differ between the groups. Of 406 women who had a TOL, 84.9% eventually delivered both twins vaginally. A significantly higher percentage of antepartum complications were noted among those who failed the TOL compared to those with successful TOL (8.2% vs. 1.7%, p = .01). The number of neonates with pH of less than 7.0 did not differ between the groups although more neonates (2.5% vs. 0.4%, p = .05) among the failed TOL had an Apgar score of less than 7.0 at 5 minutes compared to successful TOL. Vaginal delivery of both twins after TOL occurred in 91% of vertex/vertex compared with 71.8% of vertex/nonvertex presenting twins (p < .01). Neonatal outcomes did not differ between both groups. Our results indicate that both vaginal and PCS are comparable options for vertex presenting first twin regardless of second twin presentation.

    ABSTRACT: Abstract Objective: We aimed to characterize risk factors for combined twin delivery and assess neonatal outcome. Methods: This was a retrospective cohort study of all women admitted for trial of labor (TOL) with twin gestation, in a single, tertiary, university-affiliated medical center. Eligibility was limited to gestations with twin A delivered vaginally. Results: During the study period, 44,263 women delivered in our center, of whom 1,307 (2.9%) delivered twins. Overall, 221 out of 247 women (89.5%) undergoing TOL delivered twin A vaginally. Parturients who delivered twin B by cesarean delivery (n=23) were compared with those delivered twin B vaginally (n=198). Multivariate analysis demonstrated that risk factors combined delivery were included non-cephalic twin B at admission (aOR 11.5, 95% CI 3.8-34.9, p<0.001) or after delivery of twin A (aOR 17.7, 95% CI 6.6-47.2, p<0.001), and dichorionic-diamniotic twins (aOR 8.9, 95% CI 1.8-44.0, p=0.008). Spontaneous version of a cephalic twin B was not found to increase the risk (above the baseline risk of non-cephalic twin B) for combined delivery. Combined delivery was associated with slightly higher risk for hemorrhagic-ischemic encephalopathy of twin B (4.3% vs. 0%, p=0.003). Conclusion: Non-cephalic twin B at admission or following delivery of twin A poses higher risk for combined delivery. Neonatal outcome of twin B following combined delivery are comparable with those of vaginal delivery.

    ABSTRACT: Abstract Objective: To evaluate the perinatal outcomes and clinical factors of unsuccessful trials of labor (TOLs) in late preterm and term twin pregnancies. Methods: We enrolled 896 consecutive twin pregnancies delivered between 1999 and 2012 in a single center, which met the following inclusion criteria: a vertex first twin, live twins, and attempted TOLs after 34 weeks. Obstetric characteristics and perinatal outcomes were compared between vaginal delivery and cesarean delivery groups. Results: Successful TOLs were carried out in 81% (726/896). Failed TOLs occurred in 15% (37/247) of late preterm twins and 20% (133/649) of term twins. Comparisons of neonatal outcomes between the groups showed no significant differences in NICU admission, ventilator use, and composite morbidity. On univariable analysis, nulliparity, preeclampsia, induced labor, excessive weight gain, and intertwin weight discordance of >30% showed significant associations with failed TOLs. Multivariable analyses revealed nulliparity (adjusted odds ratio 9.89, 95% confidence interval 4.64-21.1) and preeclampsia (adjusted odds ratio 2.17, 95% confidence interval 1.30-3.63) as significantly associated with failed TOLs. Conclusion: In late preterm and term twins, trials of labor can be performed successfully without a significant increase in adverse neonatal outcomes. Nulliparity and preeclampsia are clinical factors associated with failed TOLs in twin pregnancies.

    ABSTRACT: Plexiformneurofibromas (PNFs) are benign nerve tumours resulting from aberrant growth of cells of nerve sheath. PNFs are generally painless, slow growing neoplasms. Although most neoplasms are asymptomatic, they can be particularly debilitating due to their potential to grow to very large sizes. They have potential for transformation into highly malignant peripheral nerve sheath tumours which occur in approximately 5% of patients. They can affect most parts of the body. When they occur in the chest wall, they are amenable to excision. Following excision, a surgeon is faced with a large skeletal and soft tissue defects which pose functional and cosmetic challenges. We present a 24-year-old farmer that presented with a giant anterior chest wall plexiformneurofibroma that was noticed since childhood. He had excision of the mass and skeletal reconstruction with methylmethacrylate sandwiched in prolene mesh and softtissue coverage with vertical rectus abdominismusculocutaneous flap. We conclude that the use of methylmethacrylate and myocutaneous flaps give both good functional and cosmetic outcome following excision of large chest wall tumours.
